Topic: “Contamination of Agricultural Soils and its Conservation with Phytoremediation
technology”
Abstract- Extensive contamination of agricultural soils with various heavy metals has been a
great health concern worldwide, because of their potential reactivity, toxicity, mobility and
long-lasting effects on the ecosystems. There is a great need to develop effective technologies
for treatment of these contaminated soils as recoverable soil resources. There are some
conventional soil treatment technologies including physicochemical and thermal processes,
anyway, they are usually extremely expensive, and destroy the soil bio-productivity, possibly
leading to the loss of soil resources.
Recently, phytoremediation as a cost effective and environmentally friendly soil treatment
technology has been developed, in which green plants are used to remediate the contaminated
soils without destroying the soil properties. The traditional phytoremediation are mainly used
special plants known as hyperaccumulators.
In the current report, the characteristics and development of phytoremediation were
introduced, and a profitable phytoremediation strategy was suggested. The profitable
phytoremediation used resourceful plants, instead of the special hyperaccumulator plants, for
both utilization and remediation of the contaminated soil. In this strategy, the owners of
contaminated sites possibly cost nothing, but can obtain economic income through selling the
resources crops to factories for production of biofuel or to the market as ornamental flowers.
Through this way, the practical application of phytoremediation can be effectively promoted,
and then the agricultural soil resources can be conserved.
To test the feasibility of the suggested strategy, experiments from pot culture to field
demonstration were carried out. The results showed that phytoremediation using resourceful
plants work effectively for remediation of contaminated soils as well as for generation
economic benefits to the owners of contaminated sites. Therefore, we suggest the profitable
phytoremediation system as a reasonable choice for remediation of contaminated sites. (This
work was supported by JSPS KAKENHI No.16H05633).

Topic: “Quality, Quality Shifting, and Positioning of Night Interruption Light Affect
Flowering, Morphogenesis, and Photoperiodic Gene Expressions in Chrysanthemum”
Abstract-The quality, quality shifting, positioning and supplementary night interruption light
(NIL) on morphogenesis, flowering, and photoperiodic gene expressions was investigated in
Dendranthema grandiflorum ‘Gaya Yellow’ (qualitative short day plant, SDP). The plants
grown in a closed-type plant factory under a light intensity of 100 μmol m-2
s-1
PPFD provided
by light emitting diode (LEDs) under four different treatments with different sub-treatments
(methodology section). Our results propose that morphogenesis, flowering, and transcriptional
factors of chrysanthemum were highly affected by quality and position of the NIL. The
morphological and physiological results showed that NI-B light was essential for growth and
development. The photoreceptor gene expression analysis (phyA, phyB and cry1) perceived
NI-R and NI-Fr in all four treatments by increasing their expression levels for early flower
initiation, visually also seen in our morphological results. Further, our results also indicated
that the NI-B onto the OL has a potential applicability to use in production of potted SDPs
due to subsequent height inhibition. Additionally, our results represented a useful practical
technique for flowering control as an alternative method of using the blackout curtains during
the LD seasons.

Topic: “Trapping of Particulate Matters Transported by Westerly Downslope Wind Storm in
Thermal Internal Boundary Layer due to Easterly Onshore Wind in the Korean Coast for a
Dust Storm Period”
Abstract- Hourly variations of particulate matters (PM10, PM2.5, PM1) measured by
GRIMM-1107 Aerosol Sampler were analyzed from May 5 to May 13, 2007. Before a dust
storm period, until May 7, 2007, PM10, PM2.5 and PM1 concentrations near the ground were
very low with no influence of dust transportation from China to an eastern coastal city
(Gangneung), Korea. Their maximum values of each PM concentrations were 62.28μg/m3
,
43.07μg/m3
, 30.75μg/m3
, while their minima were 26.46μg m-3
, 22.28μg m-3
, 14.02 μg m3
,
respectively. For a dust storm period on May 7 ~ 8, when a great amount of dust transported
from China to the city in the Korean eastern coast under a westerly wind, PM10, PM2.5 and
PM1 concentrations reached maximum values of 357.48μg/m3
, 83.04μg/m3
, 65.76μg/m3
,
respectively. Otherwise, their minima were 52.04μg/m3
, 28.34μg/m3
, 21.83μg/m3
, which were
still bigger than ones before the dust period. In the period of dust storm period, coarse
particulate matter (> 2.5 μm) rather than fine particulate matter (2. 5 μm and 1 μm ) mad a
great contribution to the formation of high PM concentrations at this city. As cold front
passed by the city on May 8, the original northwesterly wind shifted into southwesterly wind,
which blew down from Mt. Taegulyang (895m height) in the east of Gangneung city toward a
downwind side (Gangneng city) and became a strong downslope wind storm of 21.5m/s.
This westerly wind storm confronted easterly onshore wind consisting of both easterly
cyclonic wind and sea breeze) from the East Sea toward the city, resulting in a calm cavity
covering the whole city. Streamline calculated by WRF-3.6 numerical meteorological model,
air trajectory by Hysplit model and TOMS Aerosol Index showed that huge amounts of dust
particles transported from both Gobi Desert and Nei-mongo in the northern China toward
Gangneung city of Korea and the transported dust particles might combine with local
particulate matters or gases emitted from vehicles on the road of the city and should be
trapped and merged within a calm zone of shallower thermal internal boundary layer in the
coastal city, resulting in maximum PM concentrations at 1700LST, May 8. Just before sunset.

Topics “Challenge for Development of the Surgical Robot”
Abstract- Recently, robotic surgery using the surgical robot such as da Vinci surgical system
has been performed clinically in the field of laparoscopic surgery. On the other hand, most
recently, the type of operation called single-port surgery (SPS) has been performed in the field
of laparoscopic surgery by surgeon. Unlike the conventional laparoscopic surgery, in SPS,
multiple surgical instruments are inserted through only one incision hole on the umbilicus.
SPS can further reduce the stress on the patient during laparoscopic surgery. However, SPS
requires surgeons to have an advanced technique and experience because the surgical
operation is performed in a limited space.
In this talk, the haptic surgical robot for single-port surgery developed in our laboratory,
termed "HASROSS", is presented. HASROSS consists of two robotic arms with forceps
manipulator and one robotic laparoscope. The robotic arms with forceps manipulator are
manipulated by haptic input device Omega 7 made by Force Dimension Inc. In addition, a
grasping force of the forceps and a force added to the forceps shaft are fed back to the surgeon
through the Omega 7. While, the robotic laparoscope is controlled by using a motion sensor,
"Kinect for Windows", so that the surgeon can operate the laparoscope with his/her head
motions. Some experimental results are shown and discussed.

Evaluating the effectiveness of the combined effect of ultrasound and copper sulphate,
potassium permanganate and hydrogen peroxide on Microcystis aeruginosa
Xiaoge Wu and Junli Liu
Yangzhou University, China
Abstract- Harmful cyanobacterial blooms are increasing environmental issues and required
novel removal technology since the required doses of algaecides may cause further
environmental pollution or treatment facility damage. This study suggests the ultrasound
mediated transfer of algaecides as a promising high efficiency and low energy cost strategy
for harmful algal control. We evaluated the effectiveness of copper sulphate, potassium
permanganate and hydrogen peroxide combined with 40 kHz (0.14 W/cm3) and 800 kHz
(0.03 W/cm3) ultrasound. Copper sulphate combined with 800 kHz (0.03 W/cm3) ultrasound
leads to 30% of cell lysis. Potassium permanganate combined 800 kHz (0.03 W/cm3) within
30 seconds sonication showed an oxidation effects of most of the cyanobacterial cells. Low
doses of hydrogen peroxide combined with ultrasound slightly reduced M. aeruginosa
population. 800 kHz (0.03 W/cm3) is recommend since it could promote intracellular
algaecides delivery without high energy cost which may due to the mechanical resonance
impelled by the ultrasound forming stable cavitational oscillation. This is the first report that
illustrates the usage of high frequency ultrasound at low intensity to promote algaecides into
cyanobacterial cells.

Public’s willingness to pay for expanding the solid refuse fuel facilities in Korea: A contingent
valuation study
Hyo-jin Kim and Seung-Hoon Yoo
Seoul National University of Science & Technology, Republic of Korea
Abstract-Solid refuse fuel (SRF) is a solid fuel which is produced from non-hazardous
combustible waste. When we use SRF as an energy source rather than fossil fuel, SRF can
mitigate greenhouse gas emissions compared with the fossil fuels. For this reason, the
expansion of the SRF manufacturing and utilizing facilities is widely demanded in Korea so
as to reduce waste disposal, decrease the crude oil imports, and respond to climate change.
Thus, the Korean government is considering the enhancement the ratio of combustible waste
into SRF from 16% in 2014 to 100% in 2020. In order to expand the utilization of the SRF,
the number of SRF utilizing facility multiplies fourfold in 2020. This study attempts to assess
the public’s willingness to pay (WTP) for the expansion of the SRF facilities in Korea. To this
end, a contingent valuation (CV) survey of randomly selected 1,000 households was
conducted in Korea by using person-to-person interviews. We used one-and-one-half-bound
dichotomous choice question in the CV survey and applied the spike model to deal with the
zero WTP responses. The results show that the yearly mean WTP for the expansion of the
SRF facilities is estimated to be KRW 2,479 (USD 2.17) per household, which is statistically
significant at the 1% level. The aggregate national value amounts to KRW 46.4 billion (USD
40.5 million) per year. This information will be useful in evaluating and planning SRF
policies and projects.

Measuring Perform-Achieve-Trade: Analysis of Indian Cement and Pulp & Paper Industries
Hena Oak
Jawaharlal Nehru University, INDIA
Abstract- India launched the Perform-Achieve-Trade (PAT) scheme for firms in the eight most
energy intensive industries in 2007. The purpose was to induce efficient use of energy through
trade in Energy Saving Certificates. The scheme identified the most polluting firms from each
of these industries and set individual energy intensity reduction targets. The first PAT cycle
runs from 2012-2015 and targets have to be met within this period. This is the first time India
has adopted tradable permit scheme for dealing with an environmental problem. The objective
of this paper is to quantify the PAT effect for two out of the eight identified industries viz.
Cement and Pulp & Paper industries. The paper uses difference-in-differences to estimate the
energy intensity of firms in the implementation years. The technique of difference-in-
difference-in-differences is used to get even more robust results. Finally an OLS model is
estimated to include other factors that influence the energy intensity of firms from these two
industries. The paper finds PAT did not have a significant impact on the average energy
intensity, but the coefficient of triple interaction term is significantly negative. All other
explanatory variable shave the expected signs.

Administration and Regulation: A study of Taiwan’s Interior Design and Construction
Regulatory System
Chih-Yuan Chang
Architecture and Building Research Institute, Ministry of the Interior, Taiwan
Abstract- The establishment of the interior design and construction regulatory system was
triggered by the 1995 Wei-Er-Kang Restaurant fire incident which caused a high death toll.
Pressed by public opinion and the will of the people, the government finally revised the
building administration law and regulations substantially and tailored interior design and
construction law and regulations according to the environment and system of Taiwan.
Taiwan's interior design and construction administration system was built for the
administration of two targets: people, the action subject, and buildings, the object. The system
was modified in three stages. The study found that the system is characterized by a graduation
transition from the initial public safety protection orientation to putting emphasis on
simplifying the interior design and construction system, modifying the interior construction
permit application, and implementing the certificate renewal and retraining systems for
interior design and construction companies and professional technical personnel to improve
professional quality.

Spatial Justice: Creating a Unisex Restrooms in Taiwan
Chih-Yuan Chang
Architecture and Building Research Institute, Ministry of the Interior, Taiwan
Abstract- This study recommended that Taiwan’s unisex restroom designs, on the basis of
building usage types and public usage characteristics, be divided into single and complex
types in order to adapt to local conditions. In addition, in furthering the use of unisex
restrooms, governments should not only consider the standpoint of the user (such as male,
female, transgender) in design and planning, but also take into account general users’
experience. Based on the concepts of the United Nations’ “Convention on the Elimination of
all Forms of Discrimination Against Women" for the elimination of discrimination against
women (such as elderly or handicapped women), equality of acquiring resources and
gender-equal rights, the unisex restroom indeed needs to be set and the State should take
appropriate measures to protect the rights of women.

Classification of Urban Climate Zones (UCZs) to Understand Urban Heat Island Phenomena
Dongwoo Lee and Kyushik Oh
Research professor in the Research Institute of Spatial Planning & Policy, Hanyang University,
Seoul, Korea.
Abstract- In order to achieve effective urban heat island mitigation, it is necessary to
understand and apply urban climatic information in urban planning. In this regard, the urban
climate zone (UCZ) concept is useful in urban thermal environment planning because it offers
integrated information on climate characteristics and related spatial elements. Therefore,
in-depth investigation should be conducted on the relationship between urban climate
phenomena and urban spatial elements through systematic and scientific analysis.
This study consists of four parts. First, weather observation data were obtained from 280
AWSs (Automatic Weather Stations), which were observed on cloudless days with
moderate-low wind speed. Using these data, air temperature maps of the study area were
prepared by natural neighborhood interpolation method. Next, potential independent variables
were prepared as a GIS DB, including topography, land use, land cover, urban form, human
activities, and locational characteristics to predict air temperature. Third, influential urban
spatial elements were identified to classify UCZs by step-wise regression analysis. Finally,
UCZs boundaries in the study area were delineated by K-means clustering analysis. In
addition, the spatial characteristics of each UCZ were identified.
As a study result, impervious surface area ratio, building surface fraction, albedo, spacing
from green spaces, and spacing from subway stations, and NDVI were determined as
significant variables. In addition, UCZs in study areas classified into mountainous areas,
urban forests, urban parks, high-rise built up areas with green spaces, low-rise built up areas
with similar building height, mid-rise built up areas with roads, mid-rise built up areas with
many buildings, high-rise built up areas, high-rise built up areas with roads, and mid-rise built
up areas without green spaces.
Through a series of statistical analyses, this study was able to identify more detailed and
clearer UCZ boundaries (100m×100m) and explain statistically significant urban spatial
characteristics for better understanding of urban climate phenomena. The methods presented
in this study can be effectively applied to other cities that have similar weather conditions and
urban development patterns.

Improving the Thermal Environment in Socially Vulnerable Areas in Seoul through Green
and Grey Infrastructure
Heeju Kim, Kyushik Oh, Dongwoo Lee
Department of Urban Planning and Engineering at Hanyang University in Seoul, Korea
Abstract- Seoul is a representative city of Korea for its excessive urban developments and
lack of sufficient green space due to its high-density land use. As a result of the increasingly
built-up areas (of land cover) and impervious surface ratio by urbanization, average urban
temperatures have been rising, which has led to higher instances of the urban heat island
phenomenon. The urban heat island effect in turn, can alter or directly control urban air
circulation patterns that can eventually and significantly negatively impact the lives of the
public. In worst case scenarios, fatalities occur and thus, it is urgent that preparations be
rendered in the form of practical policies aimed at reducing air temperatures and urban heat
island areas.
There have been various efforts underway to employ green and grey infrastructure in the form
of green roofs, street trees planting, cool roofs and cool pavements on the road. Recently, the
thermal environment in Seoul has become a growing concern and is particularly problematic
to vulnerable social groups including the elderly, children, and members of low-income
households. Therefore, the role of green infrastructure as a means to reduce urban
temperatures in heat vulnerable areas needs to be more emphasized.
The purpose of this study is to identify and introduce a new urban green infrastructure to
improve the thermal environment, and specifically targets urban heat vulnerable areas. First,
to determine heat vulnerable areas in Seoul, mapping of air temperatures was conducted with
Automated Weather Station (AWS) data to pinpoint urban heat island areas. Second, after
examining the social characteristics of the population and economic indicators for the elderly
population (>65 years), the population of the very young (<5 years), and low-income
members, the location of all these groups was ascertained within urban heat island areas. Then,
overlapping urban heat island areas and the spatial distribution of the socially vulnerable
groups was conducted to identify urban heat vulnerable areas. Third, ENVI-met simulations
were implemented to analyze the effects of air temperature reduction by introducing green
and grey infrastructure in the heat vulnerable areas.
The study results determined urban heat vulnerable areas to identify areas for the new urban

green infrastructure and estimated the urban temperature reduction effects through senario
analyses of various new green infrastructure for socially vulnerable groups in Seoul. Such
results can be used as a basis for urban green infrastructure planning for improvement of
environmental welfare for socially vulnerable members within heat vulnerable areas.

Analysis of the Changes in Urban Thermal Environments Considering Development Densities
(FAR and BCR)
B. Park, K. Oh, and S. Hong
Hanyang University, Korea
Abstract- Due to recent global climate changes and higher concentrations of populations
around the world, cities have been more frequently experiencing phenomena such as heat
waves and tropical nights during the summer. This can be said to be the result of the
relationship between air temperature increase and thermal comfort degradation. Research on
this subject is significance for their impact on the quality of life for urban dwellers as well as
for their recommendations on sustainability for future generations. This study selected three
analysis areas of the urban thermal environment that have been exacerbated in Seoul. Changes
in the present conditions of urban thermal environment and in urban development form and
density were analyzed in relation to temperature and thermal comfort. As a result, the
temperature of the summer was found to have decreased by an average of 1°C while PET also
decreased by an average of 0.5 °C when building coverage ratio(BCR) was reduced by 10%,
even though the floor area ratio(FAR) increased due to the changes in urban development
form and density. In other words, the building coverage ratio had a greater influence on the
urban thermal environment than the floor area ratio, and the reduction of the building
coverage ratio improved the urban thermal environment. This was judged to be due to the
influence of wind path and building shade caused by changes in form, size, and layout of
buildings because of the decrease of building coverage ratio. To improve the urban thermal
environment in the future, it is necessary to consider wind path and building shadow when
establishing medium- and long-term urban planning. The results of the present study can be
used as basic data for spatial decision-making of urban planning when considering
improvement of the urban thermal environment.

Replication and Occlusion Body Formation of Spodoptera exigua Multicapsid
Nucleopolyhedrovirus in a Homologous Cell Line
Sudawan Chaeychomsri, Win Chaeychomsri, Jindawan Siruntawineti, Motoko Ikeda and
Michihiro Kobayashi
Kasetsart University, Thailand
Abstract- A continuous cell line, designated SENL1, has been established from Spodoptera
exigua. The susceptibility of this cell line to its homologous virus, S. exigua multicapsid
nucleopolyhedrovirus (SeMNPV), was evaluated on the basis of cytopathic effects, virus
replication and morphogenesis in the infected cells. This cell line was highly susceptible to
SeMNPV. By 3 days postinfection (pi), 99% of the cells contained occlusion bodies (OBs).
Electron microscopy indicated that the OBs of SeMNPV produced in infected SENL1 cells
were on average significantly larger than those produced in the infected larvae. Aberrant
morphogenic characteristics such as abnormal OB formation and virion occlusion were
observed in the SeMNPV-infected cells. A significant reduction in virions and nucleocapsids
per OB was noted in the SeMNPV OBs produced in the infected cells when compared with
the OBs produced in infected larvae. However, SeMNPV OBs obtained from infected SENL1
cells were infectious for S. exigua larvae, demonstrating that virus replication in vitro yielded
viable progeny. The results from the present study suggest that the morphology and biological
activity of SeMNPV OBs are influenced by some factors both in host cells and virus
interactions. Thus, SENL1 cells may provide an in vitro system for studying possible cell
effects on SeMNPV OB morphogenesis and ODV occlusion.

Grouping Method Using Graph Theory for Agricultural Workers Engaging in Manual Tasks
Shinji KAWAKURA, Ryosuke Shibasaki
National Institute of Advanced Industrial Science and Technology (AIST), Japan
Abstract- Agricultural directors and managers might employ several grouping methodologies
of physical working members to enhance the quality of work and collaborations. In this
prospective study, the authors aim to execute and demonstrate the results of a grouping
analysis based on the spanning tree method in the field of graph theory. The participants—six
experienced agricultural manual workers and six novices—were asked to crop middle-sized
root vegetables by hand in a sitting position. The authors handled the data and executed the
analyses in VBA. The authors also used Scilab libraries and packages to execute timeline
wavelet analyses with accumulated acceleration data obtained from the outdoor agricultural
workers’ dominant lower arms and the left side of their waists. The authors present qualitative
data of the workers’ groupings using standard deviations (SD) of the vertical acceleration data.
The main index values were SD values of the acceleration data in the dominant frequency
zone. After performing the dotting process, the authors successively connected pairs of dots to
separate them into two groups. The authors developed several charts and compared them with
those from the common and validated analysis of principal components method. These
methods could be used to improve the grouping and categorizing for agri-business and related
research.

Abstract- The simultaneous use of UV-C radiation at 640 or 900 µWcm-2
and ultrasonic
energy of 13.78 W/L at 40 kHz was applied on tomatoes to study its ability to disinfect
tomatoes from microbes. Total aerobic bacteria and yeast and mold population decreased with
increase of UV-C dosage application from 0.72-10.76 kJ/m2 at constant ultrasonic energy
supply. At simultaneous treatment dosage of 6.46 kJ/m2, total aerobic bacteria reduced 2 log
reductions significantly (p<0.001). Yeast and mold survivors were undetected at higher
dosage treatment from 4.31 to 10.76 kJ/m2. Lower dosage treatment from 0.72 to 2.15 kJ/m

Evaluation of biochemical factors from mixed animal wastes feedstock in biogas production
Nanh Lovanh, Graciela M.L. Ruiz-Aguilar, John Loughrin
USDA-ARS, USA
Abstract- Animal wastes can serve as the feedstock for biogas production that could be used
as alternative energy source. The green energy derived from animal wastes is considered to be
carbon neutral and offsetting those generated from fossil fuels. In this study, an evaluation of
methane production from animal wastes with different nitrogen and carbon sources was
carried out. Anaerobic batch reactors containing different mixtures of animal wastes and
potential inhibition sources were set up to evaluate methane potential. The results showed that
methane productions increased as the solid concentrations, temperature and total carbon
increased. However, biogas production decreased substantially when ammonia concentrations
in the feedstock were high. The addition of carbon to the feedstock provided a better substrate
for methane production during anaerobic digestion of animal wastes. Methane productions
were more than several times greater from reactors with feedstock amended with additional
source of carbon than the ones with just animal wastes (e.g., swine, poultry or just dairy) or
acclimated microbes. Thus, it appears that additional carbon source is necessary to increase
methane production from animal waste anaerobic digester. Inhibitor such as ammonia appears
to hinder the biomethanation in the anaerobic digestion of animal wastes for optimum
methane production.

Determinants of indigenous fruits consumption frequency among rural households: Evidence
from Mutale local municipality, South Africa
Rudzani Nengovhela, Amon Taruvinga and Abyssinia Mushunje
University of Fort Hare, South Africa
Abstract- Rural households across South Africa experience food and nutritional insecurity.
Given the claimed nutritional benefits of indigenous fruits (IFs), their availability and
accessibility in rural areas, several researchers believe they can significantly contribute to
rural household food and nutritional security. However, literature highlights that their
consumption in recent years has generally remained low and in some incidences reported to
be declining. This paper investigated factors that influence indigenous fruits consumption
frequency among rural households using 200 randomly selected households from 10 villages
in Mutale local municipality, South Africa. Results indicate that a majority of the respondents
(78%) consumed indigenous fruits on weekly to monthly basis, mostly in summer when they
are abundantly available. Several socio-economic and perception based factors are estimated
to condition rural households’ indigenous fruits consumption frequency worth targeting. We
therefore argue that, caution should be exercised when indigenous fruits are targeted as food
and nutrition security supplements for rural households bearing in mind the periods of the
year they are available and drivers of their consumption frequency.

Honey value addition initiatives selection choices among smallholder beekeepers: Case of the
Eastern Cape Province, South Africa
Tina Hans, Amon Taruvinga and Abyssinia Mushunje
University of Fort Hare, South Africa
Abstract- The aim of this study was to determine factors that influence honey value addition
selection choices among smallholder beekeepers. This was against a background where honey
value addition is reported to be very low, yet very beneficial in terms of formal market access
and increased revenues. A census of all active smallholder beekeepers in the Eastern Cape
Province during the period of study was considered for this study. Using descriptive statistics
to profile most common value addition initiatives pursued by beekeepers, the study found that
liquid honey processing, bottling and beeswax processing were the major value addition
pursued by the farmers. Regression estimates revealed that honey value addition selection
choices among smallholder beekeepers were mainly conditioned by; gender, household size,
group membership, training, quantity of honey harvested, number of colonized hives, access
to market information and extension services. Several policy insights were generated mainly
focused on institutional and technical support.

The Use of Transferable Breeding Container For Population Enrichment Of Pollinator,
Forcipomyia spp. In The Cocoa Ecosystem
Saripah Bakar, Alias Awang
MALAYSIAN COCOA BOARD, Malaysia
Abstract- The study aims to investigate the potential use of breeding substrates (cocoa pod
husk, banana stump, and combination of cocoa pod husk and Cocoa pod borer infested pods)
for an enhancement population of pollinators, Forcipomyia spp. (Diptera: Ceratopogonidae).
The numbers of pollinators was monitored at intervals of two weeks at four distances (2, 5, 8
and 12 m) from the breeding sites. This observation was carried out for the period of 94 days.
Field study demonstrated that the emergence of pollinators was higher at Day 52 (2.875a),
and significantly different with Day 66 (1.563bc), Day 80 (1.250bc), Day 12 (1.042bc), Day
94 (0.792c) and Day 1 (0.792c). The numbers of male (1.063a) and female (1.813a)
pollinators were recorded highest at Day 52. Cocoa pod husk recorded the highest number of
male (1.115a) and female pollinators (0.792a), followed by banana stump, control and
combination of cocoa pod husks and CPB’s infested pods. Higher number of pollinators were
recorded at a distance of 2 m (1.7600a) from the breeding sites, followed by 12 m (1.740a), 8
m (1.480a) and 5 m (1.323a). The overall observation suggested that cocoa pod husk can be a
good breeding substrates for cocoa pollinators.

An assessment of community’s perceptions of IK based handicrafts in Amathole District
Municipality, South Africa.
Raphael Mudemba, Amon Taruvinga and L. Zhou
University of Fort Hare, South Africa
Abstract- The use of Indigenous Knowledge (IK) based skills and technologies in the rural
livelihood activities have been practiced for ages. However, there are fears that rapid
modernization is driving deprecation of such retro technologies in society. Thus, studying
communities’ perceptions of IK based technologies in off-farm livelihoods activities could be
conducive to further development and poverty alleviation in rural communities. The use of
Indigenous Knowledge-based technologies and skills in crafts activities is a major livelihood
contributor to rural households in South Africa. The present study employed a cross-sectional
survey of 300 households in Amathole District Municipality of South Africa to assess
communities’ perceptions of the use of IK based technologies in handicrafts making. Results
indicate a strong regard for Indigenous Knowledge-based technologies and skills in off-farm
livelihood strategies and environmental management. We, therefore, urge for a policy
framework that recognizes and promote the use of such tacit knowledge in alleviating poverty
and food insecurities in rural areas.

(Nihon Millipore Ltd., Yonezawa, Japan)]. All cultures were maintained in a culture room
with 70% relative humidity (RH), and 300 μmol·m-2·s-1 photosynthetic photon flux density
(PPFD) and a 16 h (day)/8 h (night) photoperiod provided by white light emitting diodes
(LED). After six weeks of culture the growth traits, photosynthetic capacity, and biochemical
markers such as activities of antioxidant enzymes and contents of nutrients were measured.
The results showed that growth and development of carnation plantlets were strongly affected
by the presence of 3% sucrose in the medium as higher percent recoveries were observed in
the sucrose-containing treatments. Further increase up to 80.3% in recovery was observed in
the treatment of 3% sucrose plus 100 mg∙L-1 Si supplementation. However, these plantlets
had shoots shorter in length and had lower chlorophyll contents than those in the other
treatments. On the other hand, growth traits such as fresh weight, dry weight, shoot length,
and root length were improved in the lower, 50 mg∙L-1 Si treatments. In conclusions, sucrose
and Si had a synergy effect for enhanced recovery, and also for growth and development of
micropropagated carnation ‘Green Beauty’. These findings may be utilized for solving the
problems of hyperhydricity in other carnation cultivars also.

Abstract- Codonopsis lanceolata is a vine plant native in South Korea and belongs to
Campanulaceae family. This plant is cultivated in a number of places in Korea, and its root is
used in traditional medicines as antitussive, expectorant and antidote. In the transplant
production stage, compactness and uniformity are important to achieve high-quality
cultivation afterward. However, this aspect has seldom been investigated to produce compact
and uniform seedlings of C. lanceolata. In this study, seedlings of C. lanceolata were grown
with different LEDs for four weeks in a glasshouse with an average daily maximum light
intensity of 490 μmol·m-2·s-1 PPFD coming from the sun (50% shading, the highest instant
light intensity of 580 μmol·m-2·s-1 PPFD) with 16 h/day of supplemental lighting at 200
μmol·m-2·s-1 PPFD from either blue LED (LED-B), red LED (LED-R), white LED
(LED-W), or mixed (white: red: blue =1: 1: 2) LED (LED-M). The environmental condition
was 32/25 ℃ day/night temperatures, 85% relative humidity, and a natural photoperiod of 14
h. The average internode length, epicotyl length, hypocotyl length, and shoot length of
seedlings under the LED-B were significantly shorter than those under LED-R, LED-W or
LED-M. Furthermore, the shoot density, including the ratio of dry shoot weight to shoot
length or fresh shoot weight to shoot length of seedlings, was significantly greater than those
under LED-R, LED-W or LED-M. Overall, the results showed that LED-B treatment
benefited the production of more compact and uniform seedlings of C. lanceolate.

Climate Change Effects on Plants
Ebru Orhun
Çanakkale Onsekiz Mart University
Abstract- According to the Fifth Synthesis Report on Climate Change Panel (IPCC),
increasingly consumption of fossil fuels of human being with the largest contribution to the
global warming, including CO2, CH4, N2O, water vapor as by factors of greenhouse gas
(GHGs) formed which is caused the temperature to increase progressively of the world. In
this case, it is not possible to get back, gradually in the agricultural sector, one of the industry
that is found to have the highest sensitivity to the global warming, is getting felt more severe.
So that is an integral part of the plants (hence plant production) and because they are still
prone or vulnerable to the effects of global warming is clear. Researches showed that effects
of global warming on plants; plant germination and growth and these were also reflected into
their production. In this study, the effect of global warming on plant and plant growth which
is the subject of our communique was discussed in general terms and explained with relevant
examples.

Himalayan Institute of Pharmacy & Research/Department of Agriculture, Atak Farm,
Rajawala-248007, Dehradun, Uttarakhand, India.
Abstract- Apple powdery mildew epidemics, caused by Podosphaera leucotricha (Ell. and Ev.)
Salm. can be readily described in terms of the disease triangle. The role of different
environmental factors, viz., temperature, relative humidity, leaf wetness, sunshine and rainfall
were studied in relation to disease development. The present experiment was conducted
during the season 2003 to 2005 to determine a simplified assessment procedure by which
apple powdery mildew severity/index could be predicted from incidence data and develop
incidence-severity relationship in apple cultivars under Uttaranchal hilly conditions. The use
of percentage scales and keys of visual disease severity, remote sensing, and some indirect
methods like spore counts and disease incidence are considered valid approaches for disease
assessment. The relationship between increase in incidence of powdery mildew in relation to
severity can be established either by making sequential records in one tree during the progress
of an epidemic or by assessing many trees with different amounts of disease at one point of
time. The combination of several factors like the presence of susceptible host, virulent
pathogen, and congenial environment for disease development during receptive phenological
stage of apple tree was responsible for the incidence of the powdery mildew on apple.

Performance and combustion characteristics of a diesel engine fueled with waste vegetable
oils
Abdullah A Abuhabaya
King Abdulaziz University, KSA
Abstract- The present study aims to investigate the impacts of biodiesel blend ratio on
biodiesel’s performance, combustion and emission characteristics. Experiments were
conducted using JCB 444 TCA 74kW engine for neat biodiesel B100 and its blend fuels with
B5, B10, B15,B20, B30 and B40 of biodiesel at different engine speeds and loads conditions
without exhaust gas recirculation. The indicated engine power and torque using biodiesel
were found to be lower than that of using diesel fuel for all of tested loads. The decreased of
engine power and torque with biodiesel can be attributed to the lower calorific value of
biodiesel. An obvious decrease in carbon monoxide (CO) and total hydrocarbon (THC)
emissions was attained with the addition of biodiesel. Moreover, emissions of nitrogen oxides
(NOx) were simultaneously reduced compared with using standard diesel fuel at low to
middle loads. Finally, the strategy with biodiesel blends showed better combustion, emission
characteristics as well as economy performance among all the fuels. For the efficient use of
biodiesel blend fuels, it is suggested that the blend ratio should be carefully selected based on
the engine operating conditions.

Exploration in Afghanistan
Mohammad Abed Anwarzai, and Ken Nagasaka
Tokyo University of Agriculture and Technology, Japan
Abstract- The future green world, without of greenhouse gases, is possible to produce the
electricity from the renewable energy resources. The geothermal is one of the most potential
clean energy sources to be developed in the next century. The geothermal energy potential
study needs the temperature value and amount of stored heat in the underground rocks. The
purpose of this research is to determine the earth crust temperature at the depth of 3.5 to
10.5km for geothermal energy potential calculation in Afghanistan. The temperature at depth
prediction model is based on the tectonic ages, tectonic activity, geological structures, and hot
spring data. To achieve this goal, in GIS, the earth crust thickness, sediment thickness, surface
heat flow, mantle heat flow, and surface temperature have been mapped. The temperature
calculation formulas, as a function of depth, were applied in GIS model to estimate the
temperature at depth. The analysis contains the sediment and basement contribution along
with surface temperature correction considering the constant thermal conductivity and
radioactive heat generation in the crust. The resulting maps are plotted for each km of depths
from 3.5 to 10.5km. The calculation result is in the range of; minimum 39°C and maximum
347°C average temperature at the depth of 3.5km and 10.5 km respectively. The huge
geothermal energy (power production) is available; First in Helmand, Kandahar, and Herat
provinces, moreover, in northern and eastern deeper sedimentary region of the country at the
depth of 3.5km. Second in the all known geothermal fields of the country until the depth of 5
km.

Hee Joo Han, Young Ho Lee, Gyun Ro Lee, Dae Won Park
Seoul National University of Science & Technology, Republic of Korea
Abstract- In this study, we researched on feasibility of solid fuel process by torrefaction
methods by using sewage sludge. In this study, the experiment was performed by using raw
sludge generated from the first sedimentation area among sewage sludge. For torrefaction
method, the experiment was performed through 3 methods, which are drying method, fry
method, fry after drying method. When conducing drying torrefaction and fry torrefation
experiment, the reaction temperature was 200℃, 215℃ and 230℃ and reaction time was 15
minutes, 30 minutes and 45 minutes.
When conducing experiment by fry torrefaction after drying torrefaction, the reaction
temperature was fixed as 200℃, made products by progressing 15 minutes of fry torrefaction
after 15 minutes of drying torrefaction, 15 minutes of drying torrefaction and 30 minutes of
fry torrefaction, and made products not exceeding 45 minutes of total reaction time by
progressing 15 minutes of fry torrefaction after 30 minutes of drying torrefaction. For the
products generated by drying torrefaction method, we could get the reaction products conform
to solid fuel standard 3,500kcal/kg at the condition of reaction temperature content of the
product decreased to below 10% at the condition of reaction temperature 230℃ and after
reaction time of 30 minutes of reaction time. In case of reaction product generated by fry
torrefaction method, it fulfilled solid fuel standard regardless of reaction temperature and
reaction time and below 10% of moisture content. When combining drying method and fry
method torrefaction, we could remove moisture content of sewage sludge higher and could
observe the caloric value showed higher efficiency than drying torrefaction. Therefore, it was
observed that fry torrefaction method for solid fuel production of sewage sludge through
torrefaction method shows higher efficiency in terms of removing moisture content and
caloric value.

A Japanese Utility Renewable Energy Management
Amin Mohammadirad, Sho Kainose and Ken Nagasaka
Tokyo University of Agriculture and Technology, Japan
Abstract- HOKKAIDO a northern island of Japan has high potentials of Solar and Wind
energies. However, HOKKAIDO Electric Power Company (HEPCO) declares that by
increasing Renewable Energy (RE) power such as Photovoltaic and Wind generation
(hereafter PV and Wind), they cannot interconnect to the grid because of interconnection
limitation and having surplus power in the grid. In this paper, for RE surplus power
management, we suggest two solutions. The first solution is to convert RE surplus power to
another type of energy which divided into two different methods. First, convert RE surplus
power to 100% heat. Second, convert RE surplus power to 50% heat, 40% hydrogen and 10%
electric cars. For this purpose, we use the Advanced Energy System Analysis Computer tool
called “Energy PLAN” to estimate RE surplus power in HOKKAIDO future energy system.
Then, we calculate and compare the conversation economic and environmental performances.
The second solution is to transfer RE surplus power to connected multi-area networks. For
this reason, we design load frequency control (LFC) in smart grid model of IEEE 30 bus test
system in MATLAB/SIMULINK to give such ability to transfer power from one area to
another. Finally, we compare both solutions economical and environment performances.

Performance Analysis by Supporting Electrolytes for Vanadium Bromine Redox Flow Battery
Youngho Lee, Miae Kim, Joonhyeon Jeon
Department of Energy and Advanced Material Engineering, Dongguk University-Seoul,
Republic of Korea.
Abstract- A vanadium bromine redox flow batteries (V/Br RFBs) have been attracting interest
as redox flow batteries that have shared the advantages of the all-vanadium redox flow
batteries (VRFBs) but removed the disadvantages. The V/Br RFBs employ a V (II) / V (III)
couple in the negative half-cell and a Br− / Br3− couple in the positive half-cell. In this paper,
the vanadium bromine unit cell was compared with and without a supporting electrolyte and
its electrochemical characteristics were analyzed. The experimental results showed that the
discharge capacity of the unit cell without the supporting electrolyte increased to double
compared to that of the unit cell with the supporting electrolyte, but the average coulombic
and voltage efficiency decreased by 8.8 % and 3.1 %, respectively, and the average energy
efficiency decreased by about 12.1 %. In addition, as the cycle progressed in a unit cell using
without the supporting electrolyte, a water-transfer phenomenon to the cathode electrolyte
affected the stability of the unit-cell over a long-term cyclic operation. As a result, although
the discharge capacity was increased due to the stabilization of the redox reaction by no
supporting electrolyte, the stability of the unit cell was deteriorated due to the decrease in
efficiency and the problem caused by the water-transfer phenomenon. This result will be
beneficial for the choice of the electrolyte for the V/Br RFBs.

An Effect of Imidazolium as Bromine Complex Agents on Zinc-Bromine Hybrid Flow
Battery

Department of Energy and Advanced Material Engineering, Dongguk University-Seoul,
Republic of Korea.
Abstract- A zinc–bromine hybrid flow batteries are a highly efficient rechargeable battery for
energy storage system, where the electrolyte containing dissolved zinc and bromide ions
flows through an electrochemical cell that reversibly converts chemical energy directly into
electricity. The charging and discharging processes are generally achieved through a reaction
of redox couples such as Zn2+ (aq) / Zn (s) and Br– (aq) / Br2 (l) in a zinc bromide electrolyte.
But generated bromine liquid can easily damage battery material and be evaporated, so
bromine complex agents have to be used in the electrolyte. The bromine complex agents is
based on a quaternary ammonium bromide and commonly used as N-methyl-N-ethyl
pyrrolidinium bromide which can degrade electrolyte conductivity and voltaic efficiency of
the zinc–bromine hybrid flow batteries. To overcome degradation, this paper describes
3-ethyl-1-methyl imidazolium bromide as the bromine complex agent, resulting in a high
performance of cyclic operation. To show the effectiveness of the proposed solution,
electrochemical analyses are carried out using a miniature zinc–bromine unit-cell. The
solution is then compared with the conventional electrolyte solution using N-methyl-N-ethyl
pyrrolidinium bromide. Experimental results show that using 3-ethyl-1-methyl imidazolium
bromide provide 5.18 % (5.80 %) higher voltaic (energy) efficiency at the current density of
20 mA cm-2. Therefore, this paper provides that new direction about effect of the bromine
complex agents for the zinc–bromine hybrid flow batteries.

Interfacial control of transition metal -based nanostructures as electrode materials for
electrochemical sensors
Wen Zhang, Li Dong, Hongxiu Du, and Degang Fu
Southeast University, China
Abstract- Surface texture of nanostructured electrodes act as vital role in electrochemical
application. The surface structure and morphology of electrode materials will greatly affect
the activity of electrochemical sensors. Nanostructured transition metal oxides with large
surface area are beneficial to facilitating interfacial electrochemical reactions. Diffusion paths
for both electrons and ions could be shorten and interfacial redox reactions could be enhanced
due to the nanostructure characteristics. This is essential information for preparing metal
oxides products of the expected structure, and provides a strategy for modulating
nanostructure properties through their size and morphology. Accurate detection of glucose and
dopamine plays vital roles in early clinical diagnosis and disease prevention. Electrochemical
methods are drawing increasing attention due to the easy electrochemical oxidation of glucose
and dopamine. In this report, a series of transition metal -based nanostructured materials were
proposed through interfacial control of surface structures and used as electrodes for
biomolecules (glucose and dopamine) detection. The modulated electrodes materials exhibite
wide linear response ranges with high sensitivity, good selectivity and excellent
reproducibility.

Abstract- Supercritical fluid extraction (SFE) with carbon dioxide as a solvent was performed
to obtain oil from red pitaya (Hylocereus polyrhizus) seeds. The extraction process was
optimized by response surface methodology and the effects of extracting variables namely
temperature and pressure were evaluated. Central composite design was employed to develop
the model and to predict the optimum conditions. The highest oil yield was predicted to be
about 6.93 wt%, under optimal conditions of 47 oC and 4750 psi. At optimum conditions,
average experimental oil yield of 6.88 ± 0.06% was recorded and agrees well with the
predicted value. The chemical composition of the SFE and n-hexane extracted oils were
identified by gas chromatography mass spectrometry (GC-MS) analysis. GC-MS analysis
revealed negligible differences in fatty acid composition of oil extracted from both methods
with linoleic acid as the main component. In the studies of oil quality, the important
physicochemical properties of the extracted oil were also analyzed.

Subcritical CO2 Extraction, Chemical Characterization and Biological Potential of Essential
Oil from Stevia rebaudiana Bertoni
Uswatun Hasanah Zaidan, Syahida Ahmad, Azizah Abdul Hamid and Fahmi Yusof
UNIVERSITY OF PUTRA MALAYSIA (UPM), MALAYSIA
Abstract- Many aromatic and medicinal plants are available in Malaysia from which the
essential oil (EO) can be extracted for multipurpose. Stevia rebaudiana essential oil (EO) was
extracted by using subcritical carbon dioxide (SC-CO2) method for the first time and
chemically characterized by means of gas chromatography-mass spectrometry (GC-MS) and
fourier transform infrared (FT-IR) spectroscopy. The highest productivity yield of the
extracted EO was found in the stevia to ethanol ratio of 1:0.5 with 5.6%, followed by the ratio
of 1:1 with 3.6% and 1:1.5 with 2.4%, which representing 89.32%, 92.45% and 81.42% of
identified compound, respectively. The principal components in the EO were lupeol acetate,
α-linoleic acid, hexadacanoic acid, and spathulenol. Interestingly, some new compounds were
identified such as epiputranjivol, globulol, betulinic aldehyde, ionone, and γ-sitosterol which
had not previously been reported in Stevia rebaudiana EO. EO has performed the most
effective antimicrobial activity against gram-positive, B. subtilis. Furthermore, Stevia
rebaudiana EO presented interesting scavenging activity against DPPH with IC50 of 0.91 ±
0.13 µg/ml comparable with standard ascorbic acid (0.51 µg/ml) and trolox (5.83 µg/ml), thus
reflecting essential oil as an excellent antioxidant source. High product quality of SC-CO2
employed for extracting Stevia rebaudiana essential oil could be a good source of natural
antimicrobial and antioxidant as a functional food component with possible applications in
food and pharmaceutical.

High purity and concentration of acetate production via thermophilic syngas (CO/H2)
fermentation with mixed culture in a hollow fiber membrane biofilm reactor
Nan Shen, Raymond J. Zeng
Yangzhou University, China
Abstract- CO and H2 are main components of syngas. Bioconversion was a green way for fuel
production from syngas. Mixed culture fermentation (MCF) is recognized as one promising
approach to realize resources recovery.
Only acetate and little butyrate (less than 1g/L) were detected in the small reactor at 55oC.
The VFAs yield was 229.06 C-mmol/L during day 0-20 and 412.66 C-mmol/L during day
22-38. The VFAs production rate was 12.67 C-mmol/(L∙d) during day 0-20 and 26.03
C-mmol/(L∙d) during day 22-38. The performance of syngas fermentation was also monitored
within 60 days in the big HFMBR with a surface area of 0.24 m2. Both of the VFAs
production yield and rate were higher in big HFMBR than small HFMBR within the initial 20
days (867.87 C-mmol vs 229.06 C-mmol and 43.35 C-mmol vs 12.67 C-mmol). There was
25.60 g/L of acetate was detected within 20 days in big HFMBR while only 19.76 g/L within
60 days in small HFMBR. The acetate production rate increased with the membrane surface
area that should be due to the biofilm surface attached on the hollow-fibre membrane.
Thermoanaerobacterium played the main role during acetate production at 55oC in this study.

Resveratrol Production in Genetically Modified Synechococcus elongates PCC7942 via
Carbon Dioxide Conversion
LIANG-JUNG CHIEN, MENG-PING HUANG, JIAN-AN PAN
Ming Chi University of Technology, Taiwan
Abstract- Polyphenols are secondary metabolites of plants and are generally involved in
defense against ultraviolet radiation or aggression by pathogens. In food, polyphenols may
contribute to the bitterness, astringency, color, flavor, odor and oxidative stability. Plant
polyphenols have been found to be highly active in the human body, with a plethora of
health-promoting activities against a variety of diseases, including heart disease, diabetes, and
cancer, and with even the potential to slow aging.in this study, we genetically modified
cyanobacteria to produce plant polyphenol, resveratrol, via carbon dioxide conversion. We
constructed a tri-expression gene expression plasmid, pSCCA-6, encoding stilbene synthase
ligase (STS) from Vitis vinifera, an 4-coumaroyl: CoA ligase (4CL) from Arabidopsis thaliana,
and carbonic anhydrase (CA) from the cyanobacterium Synechocystis sp. PCC6803, to allow
the simultaneous CO2 conversion to HCO3- and produce plant polyphenol compound,
Resveratrol. In this system, the highest plant polyphenol compound production obtained using
STS, 4CL and CA was 756 mg/L via 10 mM p-coumaric acid as the initial precursor.

Abstract- Three recent sediment cores (P2S2, P1S1, and P3S1) about 38.5 cm – 47.5 cm
length collected from mangrove and coastal area in Cikadal Beach, Sukabumi, West Java,
Indonesia. Cikadal Beach is in the same area of Ciletuh Geopark, commonly be the main
geological object study in Indonesia. The purpose of this study is to determine
paleoenvironment and paleoecology based on recent benthic foraminifers. The methodology
is using cluster analysis; the results are two dendrograms that explain sample association and
species association. Sample association divided into 5 biofacies, which are the depositional
environment of Biofacies A Transitional – Middle Shelf, Biofacies B Transitional – Middle
Shelf, Biofacies C Transitional – Middle Shelf, Biofacies D Transitional – Inner Shelf, and
Biofacies E Transitional – Middle Shelf. Whereas, species association divided into 2

correlation of the three cores. Based on low index diversity of research area, the existence of
ecological changes simultaneously with environmental changes.

Abundance of anammox bacteria in partial nitrification-anammox (PNA) process
Qingkun WANG and Jianzhong HE
National University of Singapore, Singapore
Abstract- Wastewater treatment plants (WWTPs) have historically been operated to remove
nutrients without a clear understanding of the complex microbial interactions that are integral
to optimizing treatment processes. Anammox bacteria (AnAOB) have attracted attention
due to the potentials on saving energy and reducing organic chemical demands. Partial
nitrification-anammox (PNA) process is by far one of the most practical processes in
wastewater treatment using anammox. Sufficient partial nitrification is of importance to
retain ammonium-oxidising bacteria (AOB) but suppress nitrite-oxidising bacteria (NOB),
which is a critical parameter for sustaining the anammox process. Here we report the
recently developed PCR primers (targeting 16s rRNA genes) with higher efficiency and more
reliable to study the presence and abundance of AnAOB, AOB and NOB to assess the
performance of the PNA process. Compared to the published AnAOB primer pair, the newly
designed AnAOB PCR primer can detect more than 70% anammox bacteria strains in NCBI
GenBank database with 100% speicificity. PCR, qPCR and clone library results demonstrate
the specificity further with only one amplicon. With the kinetic tests, the newly designed
Amx primer can higher coverage percentage in three different sludge samples (13.76% vs
49.55%; 10.93% vs 20.99% and 23.43% 57.43%), which also well agreed with the AnAOB
activity measurement. AOB primer was successfully designed to target all five genera under
alpha-proteobacteria instead of single genus detection. The In silico test shows that it can
achieve up to 35% coverage (compared with most commonly used one CTO189f/RT1r with
20.5% coverage) with 94% specificity. On the other hand, NOB primer pairs were designed
to target specific single genus (i.e., Nitrobacter and Nitrospina). Both clone library and
qPCR results demonstrate the specificity of the two sets primer pairs. The In silico tests
show that the coverage can be up to 50% and 81%, respectively. These results, therefore, are
strongly to show that the newly designed primer pairs are powerful tools to study and assess
the performance of PNA process in wastewater treatment.

Community structure and Functional Species in Food / Paper Waste Reactor
Lu Li, Yu Qin, Kengo Kubota, Yu-You Li
Tohoku University, Japan
Abstract- In this study, 16 samples of were taken from anaerobic digestion sludge in two
independent systems (M and T) and a recycled system separated with mesophilic (cM2) and
thermophilic (cT1) conditions. The substrate were changed in 4 stages to elevate the ratio of
food waste (FW) / paper waste (PW) from 100 to 50 percent. Our purpose is to analyze the
variation of community structure with the increase of paper waste in the substrate. The main
bacterial genera in these two systems include Ruminococcus, Lactobacillus, Clostridium,
Coprothermobacter, Defluviitoga, Cloacamonas, Bacteroides, Paludibacter, Anaerobaculum,
Leuconostoc, Thermoanaerobacterium, Syntrophomonas and Acetobacter. Main archaea
genera include Methanothermobacter, Methanosaeta, Methanosarcina, Methanoculleus,
Methanomethylovorans, Methanomassiliicoccus, Methanobacterium and Methanospirillum.
Temperature impacted significantly in independent systems of M and T, but little to the
recycled system (include cT1 and cM2). The main factor that caused the differences of
bacteria community between cT1 and cM2 is pH. Archaea community structures of cT1 and
cM2 were similar. FW/PW ratio only had a great influence on archaea community structure in
recycled system. With the increase of paper waste, the dominant archaea groups changed from
Methanothermobacter to Methanosaeta and at last to Methanosarcina.

The influence of cyanobacterial extracellular polymeric substances on coagulation processes
Feng Sun, Aijuan Qian
Yangzhou University, China
Abstract- The hydrophobic and flocculation properties of cyanobacterial cells are closely
related to their extracellular polymeric substances (EPS). In this work, a serious of surface
characteristics of cyanobacterial cells with different EPS fractions were analyzed to evaluate
their influences on coagulation processes. With the removal of EPS fractions, the coagulation
efficiency of cyanobacterial cells was improved gradually. The microscope images of
cyanobacteria cells combined with microcystin release test showed that the cyanobacterial
cells in each EPS fraction removal phases could keep almost intact with little cell broken. The
surface of cyanobacterial cells presented higher hydrophobicity and lower zeta potential upon
deeper EPS extraction, which improved the ratio of particles in unstable state, and the
improvement level was tightly bound EPS (TB-EPS) > loosely bound EPS (LB-EPS) >
soluble EPS (S-EPS). Besides, the deeper EPS extraction further decreased the particle size of
cyanobacteria and thus increased their specific surface area of adsorption with coagulant. This
study provides scientific basis for the removal of cyanobacteria by enhanced coagulation.

A Study on Methane Production and Microbial Communities Characteristics of Psychrophilic
Anaerobic Digestion Using Food Wastewater Anaerobic Digestion Sludge as a Inoculum
Min Joo. Lee, Seoyun. Hwang, Nari. Lee and Joonhong. Park
Yonsei Universiy, South Korea
Abstract- Anaerobic digestion process which is energy effective has become an alternative to
the treatment of various organic wastewater such as food waste water. However, the heating
energy consumption of the reactor for the mesophilic digestion is a problem. To solve this
problem, research on psychrophilic anaerobic digestion were actively done.
Hydrogenotrophic methanogens which are dominant in anaerobic digestion sludge of
mesophilic food wastewater are known to be advantageous for low temperature anaerobic
digestion than acetoclastic methanogens which are dominant in mesophilic sewage anaerobic
digestion sludge. According to these findings, psycrophilic anaerobic digestion using food
wastewater anaerobic digestion sludge as inoculum can be more advantageous than using
municipal wastewater sludge as inoculation source by the small change in microbial
community due to temperature. When anaerobic digestion is carried out under low
temperature conditions, it can be superior to the mesophilic anaerobic digestion with heating
energy in terms of total energy use. In this study, low temperature anaerobic digestion
efficiencies were measured by using laboratory scale batch reactor, 16S rRNA sequencing was
performed to analyze the microbial community of each condition and economic analysis was
performed using total energy consumption at low temperature. As a result of analysis of
methane production efficiency through batch reactor, it was confirmed that when food
wastewater anaerobic digestion sludge was used as an inoculum, it showed high activity at
low temperature than when municipal wastewater anaerobic digestion sludge was used as an
inoculation source. As a result of the microbial community analysis, the microbial community
structure changed significantly according to the temperature when the municipal wastewater
anaerobic digestion sludge was inoculated. Methane production was not stable due to this. On
the other hand, Methanoculleus, a hydrogenotrophic methanogen, was identified as the same
dominant methanogen regardless of the temperature when the food wastewater sludge was
inoculated. It showed stable methane production even at low temperatures because there was
no significant change in microbial community structure. As a result of economical analysis at
low temperature, psycrophilic anaerobic digestion using the food wastewater sludge as the

inoculum was economically better than the case of the mesophilic anaerobic digestion by
adding the heating energy in the influent condition below 50,000 mg COD/L. This work
supported the feasibility of psychrophilic anaerobic digestion inoculated with food wastewater
anaerobic digestion sludge in terms of energy and cost effectiveness.

Improving transcriptional activity of human cytomegalovirus major immediate-early promoter
by mutating NF-κB binding sites
Danyang Wang, Jinke Wang
Southeast University, China
Abstract- Many mammalian gene expression vectors express the transferred genes under the
control of the cytomegalovirus (CMV) major immediate-early promoter (MIEP). The human
MIEP has been known as the strongest promoter in mammalian cells and utilized widely in
mammalian expression systems. There are four NF-κB binding sites (named as κBs) in the
human MIEP. In this study, we have constructed a multiple mutated MIEPs by changing the
natural κBs in the human MIEP into the high-affinity artificial sequences that were in vitro
selected by using systematic evolution of ligands by exponential enrichment (SELEX) and
predicted by bioinformatics. With various transcriptional activity evaluations, we found three
mutated MIEPs with the transcriptional activity higher than the wild-type MIEP, which should
be useful and widely applicable in many mammalian transgene expression fields such as gene
engineering, gene therapy and gene editing. This study provides a useful approach for
promoter engineering in biotechnology. This study also produced a series of mutated MIEPs
with various transcriptional activities, which may be used for the fine control of gene
expression output in the future synthetic biology.

On-nylon Membrane Detection of Nucleic Acid Molecules by Rolling Circle Amplification
Xinhui Xu, Jinke Wang
Southeast University (SEU) of China
Abstract- Positively-charged nylon membrane (NM) is a general solid-phase support for
nucleic acid detection due to its convenient immobilization of nucleic acid materials by direct
electrostatic adherence and simple UV crosslinking. Rolling circle amplification (RCA) is a
widely used isothermal DNA amplification technique for nucleic acid detection. Near-infrared
fluorescence (NIRF) is a new fluorescence technique with high sensitivity due to low
background. This study developed a simple method for detecting nucleic acid molecules by
combining the advantages of NM, RCA and NIRF, named NIRF-based solid phase RCA on
nylon membrane (NM-NIRF-sRCA). The detection system of this method only need two
kinds of nucleic acid molecules: target-specific probes with a RCA primer (P) at their 3′ end
and a rolling circle (RC). The detection procedure consists of four steps: (1) immobilizing
detected nucleic acids on NM by UV crosslinking; (2) hybridizing NM with specific probes
and RC; (3) amplifying by a RCA reaction containing biotin-dUTP; (4) incubating NM with
NIRF-labeled streptavidin and imaging with a NIRF imager. The method was fully testified
by detecting oligonucleotides, L1 fragments of various HPV subtypes cloned in plasmid, and
E.coli genomic DNA. This study thus provides a new facile method for detecting nucleic acid
molecules.

Effects of Fe (II) on anammox activity and functional genes expression
Ding Jing
Suzhou University of Science and Technology, China
Abstract- Anammox is an energy efficient process in biological nitrogen removal, while its
wide application is limited by the sensitive microbial activity and long cell doubling time of
the anammox bacteria. Iron is known important for the growth of anammox bacteria, but the
detailed enhancement mechanism has not been discovered yet. In this study, Fe (II) was added
into an enriched anammox culture at four different concentrations (0.03, 0.09, 0.12 & 0.75
mM), and the performance of the culture was compared to investigate the stimulation and
inhibition effects of ferrous on anammox bacterial growth and activity. The results show that
0.09 and 0.12 mM Fe (II) enhanced anammox bacterial growth and activity. 0.12 mM Fe (II)
showed superiority to improve the total anammox activity and bacterial abundance, while
0.09 mM Fe (II) led to better performance on relative anammox activity. However, the
functional gene expression level under 0.09 mM and 0.12 mM Fe (II) conditions was not
higher than that under 0.03 mM condition. It is speculated that the elevated Fe (II)
concentration may not stimulate the functional gene expression, but enhance the activity of
the final synthesized proteins. 0.75 mM Fe (II) had an immediate inhibitory effect on
anammox activity, while the inhibition seemed to be reversible. Once inhibited, Candidatus
Kuenenia stuttgartiensis may have a stress response to detoxify the Fe inhibition. This study
provides more information about the effects of ferrous on anammox bacteria, and also
proposes some instructions for future application of anammox in wastewater treatment.

Abstract- To enhance lipopetide biosurfactant production by Pseudomonas spp., the effects of
medium and culture conditions were investigated. Nutrient broth (NB) supplemented with
glucose and molasses as carbon sources were used to increase biosurfactant yield. Cultivation
temperatures and initial pH were also studied. In this experiment, NB was used as a control to
produce biosurfactant with the yield of 0.58 g/L. The lipopeptide biosurfactant yield was
increased to 2.76 g/L when Pseudomonas spp. was cultured in NB supplemented with 1% w/v
glucose, 500 µM FeSO4, pH 9.0 and cultivation of 20°C for 72 h. Its specific growth rate was

Direct butanol production from food wastes by an Amylolytic Clostridium
Chen Zhang, Jianzhong He
National University of Singapore, Singapore
Abstract- Food waste is one of the most severe environmental problem facing all over the
world, especially in mega-cities such as Singapore. To solve this problem, in this study, a
one-step fermentation process for production of butanol and hydrogen from food wastes by
amylolytic Clostridium sp. strain BOH3 is developed. Due to its advanced property of directly
synthesizing amylases (induced by starchy materials), strain BOH3 is able to naturally
hydrolyze 180 g/L of food wastes and produce 14.1 g/L of butanol and 16.2 mmol of
hydrogen. Enzymatic activity analysis shows that calcium could promote the activities of
amylases up to 33%. Thus, supplementation of external calcium ions to the food wastes
medium further improved butanol production to 16.6 g/L, which is 1.3-fold of that in a similar
study (12.5 g/L) and hydrogen to 18.2 mmol. The promoted amylase activities could shorten
the fermentation duration and enhance the butanol productivity to 0.17 g/L/h, which is
comparable to that (0.20 g/L/h) in glucose based medium. Therefore, this study offers a
promising approach to solve food waste problem and transfer them directly to biochemicals
and bioenergy.

Ali S. Vaghefi and M. Abbaspour
Yadegar-e-Imam Khomeini (RAH) Shahre Rey Branch, Islamic Azad University (IAU), Iran.
Abstract- Quantitative morphological and kinematic parameters of fish movement have been
studied here. BCF mechanism of two carangiform fish was taped by high speed digital video
and undulatory movement of each fish at different velocity was revealed. The amplitude of
this wave increases dramatically near the tail and it is very small near the head. Undulatory
movement of Pangasius sanitwongsei and Trout with different length and speed were recorded
by the digital particle image velocimetry (DPIV) and image processing methods and optimal
coefficients of the movement equations and appropriate location of joints are experimentally
derived. The velocity of fish movement can be adjusted by changing oscillating amplitude,
frequency and the length of caudal fin, respectively. Finally finding in these researches
could be applied to design a fish robot.

Investigation into the destruction potential of Zr-doped TiO2 nanoparticles for the abatement
of H2S gas
Naeem Shahzad
National University of Sciences and Technology (NUST), Pakistan
Abstract- Due to its toxicity, destruction of H2S gas has been an important topic of
researchers. Many studies have been carried for investigating various techniques for the
removal of this gas. One of those techniques is catalytic and photocatalytic destruction of H2S
gas using various catalysts including TiO2 owing to its significant potential for degradation of
various pollutants. This study investigates the destruction potential of Zr doped TiO2 for the
abatement of H2S gas. The catalysts were characterized using different techniques like XRD,
SEM, XRF. The catalytic experiments were performed using fixed bed catalyst system. The
samples were analyzed using GC-MC technique and it was revealed that the Zr doping of
TiO2 did not favour positively towards enhancing the H2S destruction potential as found in
other studies.

Aungsiri Tipayarom and Nadtapon Warigool
Silpakorn University, Thailand
Abstract- The objective of this study is to determine concentrations, emission factors, and
emission rates of PM2.5 originated from smokeless incense burnings in comparison with
common and aromatic incense burnings. PM2.5 were collected and analyzed by Dusttrak II
Aerosol Monitors Model 8530 in enclosed chamber. The ascending concentrations of PM2.5
in burning smoke were from smokeless, aromatic, and common incenses, which were 0.37,
2.06, and 2.76 mg/m3, respectively. The PM mass emission factors for the common,
smokeless, and aromatic incense burnings ranged from 0.14-0.50, 0.04-0.16, and 0.25-0.48
mg/g, respectively. The corresponding order of PM mass emission rates was 0.004-0.011,
0.001-0.002, and 0.005-0.007 mg/min, respectively. Direct variations were found between
concentration and emission factor as well as between concentration and emission rate whereas
incense densities inversely varied in concentrations, emission factors and emission rates.
Furthermore, burning rates displayed no association with other parameters.

A Common Goal: Reducing Worldwide Hazard Air Pollution from Diesel Engine Generators
Stephen Oltjen
Department of Defense, United States
Abstract- Diesel Engine Generators (DEG) are the most commonly used sources of electrical
energy generation worldwide due to diesel’s affordability and efficiency. Unfortunately, the
burning of diesel emits high hazardous air pollution (HAP) concentrations, labeling DEGs as
a major contributor to the ongoing anthropogenic damage of the environment. Enforcing
regulations on DEGs to reduce diesel emissions is necessary for environmental preservation.
In 2006 EPA established a requirement to reduce sulfur content in diesel, allowing advanced
pollution control technology such as the Discharge particulate Filter (DPF) and Selective
Catalytic Reduction (SCR) to be implemented. This equipment greatly minimizes diesel
particulate and NOx discharge. A stack analysis of a 1960s generator compared to that of a
2017 Diesel Rotary Uninterrupted Power Source (DRUPS) unit with a SCR and DPF can
prove the efficiency of the equipment. (Data to be presented during conference.)
Reducing anthropogenic HAP should be a common goal between countries worldwide.
Engineering controls have been proven to reduce diesel HAP, and should be implemented.
Achieving this goal would be a major victory in the worldwide effort on preserving the
natural environment and human health.

Graphene-Induced Surface Vacancy of Zn2SnO4 for the Enhanced Visible-Light-Driven
Photocatalytic Oxidation of NO
Wing kei Ho, Yuhan Li
The Education University of Hong Kong, China
Abstract- As a ternary complex oxide with good physic-chemical stability, Zn2SnO4 is a
promising candidate in the photocatalytic application. However, Zn2SnO4 possesses a wide
band-gap (about 3.4 eV) and it inevitably suffers the intrinsic high recombination rate of
electrons and holes. In this paper, the effect of graphene on the structure and photocatalytic
activity of Zn2SnO4 was systematically studied based on the fact that graphene exhibits a
novel electronic property such as zero bandgap, high transparency, and high electronic
conductivity for storing and transporting electrons. It was found that the presence of graphene
not only induces the formation of SnO2, but also introduces Sn vacancy, resulting in the
visible light photocatalytic activity. The photocatalyst loaded with 3.0 wt.% of graphene
shows the highest photocatalytic activity in oxidation of NO and acetone under visible light
irradiation. Graphene can efficiently transfer the photo-generated electrons from the
conduction band of Zn2SnO4, retarding the recombination of carriers and therefore enhancing
the visible photo-reactivity. A visible-light-responsive photocatalytic reaction model based on
the three-component-photocatalyst SnO2/Zn2SnO4/graphene was put forward.

Startup and kinetic characteristics of a three-stage nitrification moving bed biofilm reactor
(MBBR)
Miao Zhang, Chengda He, Yongzhen Peng, Jun Wu
Yangzhou University, China
Abstract- A two-sludge system consisting of A2/O and MBBR (Anaerobic Anoxic
Oxic-Moving Bed Biofilm Reactor) was developed. Stable and efficient denitrifying
phosphorus removal can be realized by high-efficiency utilization of influent carbon sources
in the A2/O reactor with the electron acceptors of NOx
--N in a three-stage nitrification MBBR
system (consisting of N1, N2, N3). How to successfully realize the MBBR startup was the key
for process optimization. The results showed that the biofilm matured within 18 days without
additional inoculation sludge. The average MLSS of three stages was 902.16, 678.80, 493.68
mg/L while the biofilm thickness was 95.30, 72.15, 50.28 μm, where the real-time control
parameters (pH and DO) and scanning electron microscopy (SEM) images confirmed the
improvement of nitrification performance. Meanwhile, the fluorescence in situ hybridization
(FISH) results revealed obvious differences of microbial community structure among three
stages. Additionally, the specific ammonium oxidation rate (SAOR) and half-saturation
constants of nitrification kinetics fitted by Monod equation also proved the otherness of three
stages, with KN (NH4+-N) of 2.04 - 2.31 mg/L and KO (O2) of 1.94 - 3.30 mg/L. The
incubation performances and kinetic parameters will provide theoretical reference for the
process application.

Fluidized Ceramic Membrane Reactor Combined with Activated Carbon Particles for
Industrial Wastewater Treatment
Michael Lim, Muhammad Aslam, Enyoung Park, Rizwan Ahmad, Deaun Kwon, Soomin
Chang and Jeonghwan Kim
Inha University, Republic of Korea
Abstract- There are upsurge of interests in membrane technologies for water and wastewater
treatment. Polymeric membranes have been widely applied, but they are lack of resistance
against strong chemical agents and high water temperature which is often encountered with
high-strength wastewater such as metal-finishing industrial wastewaters. The use of ceramic
membrane consisting of metal oxide (i.e., Al2O3) is very attractive to treat the industrial
wastewaters due to its excellent chemical and thermal stability over the polymeric membranes.
Nevertheless, the porous ceramic membrane as pretreatment followed by post-treatment for
further treatment itself should not be enough to improve organic removal efficiency. In this
study, new hybrid membrane system was developed by combining fluidized ceramic
membrane reactor with activated carbon particles for the treatment of industrial wastewater.
Ceramic membrane consisting of Al2O3 with 0.1 µm pore size was submerged into a fluidized
membrane reactor. Granular activated carbon (GAC) particles were fluidized by recirculating
bulk solution through the reactor. Raw heavy-metal wastewater was applied to the membrane
reactor after its pH adjustment to neutral value. Transient behavior of membrane fouling was
observed by monitoring suction pressure in permeate line from the membrane. After pH
adjustment, total organic carbon (TOC) in raw heavy metal wastewater was removed by about
50 % due to its chemical precipitation. With hybrid fluidized ceramic membrane reactor, more
than 70 % of TOC in supernatant was further removed. Total suspended solid (TSS)
concentration was near zero in membrane permeate. During 8 hr operation, no increase in
suction pressure was observed under GAC fluidization 50% (v/v) at 25 L/m2.hr of set-point
permeate flux.

3 M K2S solution to prepare sulfur-immersed materials, and the immersed-materials were
heated at 100 - 700 oC in nitrogen gas to produce the sulfur-impregnated carbonaceous
adsorbent by pyrolysis. The contents of carbon and sulfur in the adsorbent and abilities of
adsorbent to remove heavy metals from aqueous solution were examined. The product
prepared from rice husk immersed in 1 M K2S solution by pyrolysis at 300 oC indicates a
maximum removal for nickel ion. This product has the removal ability of the heavy metals,
Ni2+, Zn2+, Cd2+, Pb2+, Cu2+and Fe3+. With increasing the pH of the solution, removal of
heavy metal increase, and the order of increase for heavy metal removal is Fe3+ > Pb2+ ≒
Cu2+ > Zn2+> Cd2+ > Ni2+. The order of selectivity of the adsorbent in the mixed solution
indicates Fe3+ > Pb2+ > Cu2+ > Cd2+ > Zn2+≒ Ni2+, and the product can remove all metal
ions in the mixed solution above pH 6.

Xizi Long, Xianning Li
Southeast University, China
Abstract- In this study, a novel parallel circuit Bio-photoelectrocatalytic System was
established to enhance azo dye removal. Results showed that this system had synergistic
effects compared with the microbial fuel cell (MFC) alone. In the MFC part, a 56% decrease
in chemical oxygen demand (COD) and 85% decolorization were achieved, and further
reduced by 25% and 12% in the photoelectrochemical cell (PEC) part where titania nanotube
functioned as the photoelectrode. For one thing, the PEC raised the maximum current of the
MFC by 14.2%, which facilitated COD removal and decolorization in the MFC and promoted
adenosine triphosphate (ATP) level of anode microorganisms, for another,, this system
significantly increased the dye removal in the PEC. Besides, cyclic voltammograms
illustrated intermediate products degredation in this system. Hence, the system achieved
marked deep decolorization and rapid toxic intermediate products degradation of high
concentration azo dyes.

Fouling Mechanisms in Microfiltration with Sodium Alginate in High Ionic Strength
Conditions

Inha University, Republic of Korea
Abstract- During algae bloom, the polysaccharide and proteins extracted from algal cell can be
agglomerated and structured as “egg-box” in presence of cationic component such as calcium.
It can affect low-pressure driven membrane process as a pretreatment of seawater reverse
osmosis process and the performance of the whole process. In this study, membrane fouling of
low-pressure driven membranes was investigated with sodium alginate in high ionic strength
conditions simulated for seawater. Dead-end filtration was performed to observe fouling
behavior at constant pressure mode of 0.2 bar at various concentrations (2, 20, 50 mg/L) of
sodium alginate as model compound at fixed ionic strength. Experimental results of permeate
flux decline were also compared with traditional Hermia model to understand dominant
fouling mechanism. Based on the comparison of the experimental permeate flux values and
the numerical values obtained by Hermia models, the model describing the best the
experimental data, corresponds to the fouling mechanism responsible of flux decline. The data
comparison uses the least squares method. For lower SA concentrations (≈ 2ppm) the
permeate flux decline occurs in two phases. The first phase is controlled by pore constriction
mechanism while the second phase is controlled by cake formation model. For higher SA
concentrations (≥ 20 ppm) the flux decline occurs in one phase controlled by cake formation
model. Under conditions of high ionic strength (0.6 M) permeate flux decline registered for
different SA concentrations is lower than the values registered under low ionic strength (0.03
M), which means that high ionic strength leads to lower fouling. Moreover, two fouling
phases have been observed until SA concentration of 20ppm, while a unique fouling phase
controlled by cake formation has been observed for SA concentration of 50ppm.

Metals

Abstract- Soil contamination with heavy metals is of great concern, due to the persistence of
these toxic elements in the ecosystem and their threat to ecological safety and human health.
Phytoremediation, the use of green plants for soil remediation, is a cost-effective and
eco-friendly technology to remediate contaminated soils. In order to promote the further
utilization of spent mushroom substrate (SMS) for enhancement of phytoremediation of
heavy mental contaminated soils, maize(Zea mays) and castor oil plant (Ricinus communis)
were used as energy crops with application of SMS to study their effects on Cu and Cr
(Maize), and Zn and Cd (castor oil plant), respectively. The effect of SMS application on the
plant growth, heavy metal accumulation potential, and morphology of these heavy metals
were investigated. The results showed that SMS application enhanced the above aground
biomass yields of maize ranged from 4.6% to 27%, and castor oil plant ranged from 40% to
190%, respectively. For castor oil plants, SMS enhanced the accumulation of Cd by
140-150% in root and 120-230% in shoot relative to control soil. SMS application also
enhanced the accumulation of Cu and Cr in maize, especially in the root system. Treatments
with SMS showed significant increase in the exchangeable Cu, Cr, Cd, and Zn, indicating that
SMS enhanced the activities of these heavy metals. The total contents in the soil were found
an average decrease rate of 9.4% for Cu and 0.8% for Cr, respectively, with application of
SMS. 5% addition of SMS could improve the nutrient availability and improve the soil quality.
The present study suggests that the maize and castor oil plants treated with SMS may have
potential for enhancing phytoremediation efficiency of heavy metals and for improving soil
quality. (This work was supported by International Cooperation Project of Shanxi No.

Korea

Abstract- ‘Minamata Convention on Mercury’ was adopted in October, 2013 to protect
human health and the environment from anthropogenic releases of mercury. There is a
growing need to assess the source, transport and deposition of atmospheric Hg for evaluating
the effectiveness of the convention. In recent years, Korean researchers have also focused
their attention on the emission characteristics of mercury compounds and their behavior in the
atmosphere.
The objective of this study is to evaluate atmospheric Hg by analysing TGM concentrations
and using PSCF model in 3-4 sites of the national atmospheric Hg monitoring network from
2014 to 2016.
TGM concentrations of Tae-an was 2.10 ± 1.27 ng/㎥, Je-ju 1.56 ± 0.92 ng/㎥, Seoul 2.18
± 1.27 ng/㎥, and Incheon 2.63 ± 1.47 ng/㎥. Seasonal and monthly TGM variation in
Tae-an showed similar pattern with those of China’s background sites.
As a result of computer simulations using PSCF model, the emission contribution of local
pollution sources, such as coal-fired power plants, was high in spring, and there were no
apparent pollution sources in spring and autumn. In winter, eastern China and domestic
emission sources were simulated to have a great effect, and the results of the annual analysis
showed that the effect of long-distance movement was somewhat higher. In general, the
mercury concentrations in winter were significantly higher than those in other seasons. The
computer simulation results suggest that the long-distance movement of pollutants from
large-scale emission sources in China had a great effect. In addition, the increase of coal
consumption in winter in major domestic emission sources, such as coal-fired power plants, is
considered to have a great effect on this phenomenon.

Production of Whitening and Anti-aging materials from Lipid Extracted Microalgae
Jinwoo Kim
Department of Food Science, Sunmoon University
Abstract- Microalgae are a promising feedstock for the production of biodiesel and large
amounts of lipid extracted microalgae (LEA) are produced as a by-product. In this study, acid
and enzymatic digestion were carried out to produce peptides less than 2 kDa from proteins in
LEA. The inhibition effects of peptides on tyrosinase and collagenase activities were
examined to confirm whitening and anti-wrinkle effects. As a result of SDS, peptides from
3.4-6.5 kDa were distributed broadly in distilled water extraction, and all proteins were
hydrolyzed under 2 kDa using hydrochloric acid and commercial enzyme. Tyrosinase
inhibitory activity of extract from LEA was not detected in the distilled water extract,
however 10.5% in the 6 mol HCl hydrosate and 20.7% in the enzyme hydrosate using
protease and Alcalase were detected. Collagenase inhibitory activities were 27.9% in the
distilled water extract, 30.6% in the 6 mol HCl, and 45.0% in the Alcalase extract. Both
results indicating that the tyrosinase and collagenase inhibitory activities increased mostly
when the protein was hydrolyzed into a small molecule peptide by Alcalase. It is concluded
that LEA was possible to produce cosmetic material with increased skin whitening and skin
regeneration effects through peptide production.

One Day Tour
Tokyo, officially Tokyo Metropolis,is the capital city of Japan and one of its 47 prefectures.
The Greater Tokyo Area is the most populous metropolitan area in the world. It is the seat of
the Emperor of Japan and the Japanese government. Tokyo is in the Kantō region on the
southeastern side of the main island Honshu and includes the Izu Islands and Ogasawara
Islands.
The Sensoji Kannon temple is an ancient Buddhist
temple located in Asakusa, Tokyo, Japan. It is Tokyo's
oldest temple, and one of its most significant. Formerly
associated with the Tendai sect of Buddhism, it became
independent after World War II. Adjacent to the temple is
a five-storey pagoda, Shinto shrine, the Asakusa Shrine,
as well as many shops with traditional goods in the
Nakamise-dōri.
Tokyo Tower is a communications and observation tower
in the Shiba-koen district of Minato, Tokyo, Japan. At 332.9
metres (1,092ft), it is the second-tallest structure in Japan.
The structure is an Eiffel Tower-inspired lattice tower that
is painted white and international orange to comply with
air safety regulations.
Built in 1958, the tower's main sources of income are
tourism and antenna leasing. Over 150 million people have
visited the tower. FootTown, a four-story building directly under the tower, houses museums,
restaurants and shops. Departing from there, guests can visit two observation decks. The
two-story Main Observatory is at 150 metres (490 ft), while the smaller Special Observatory
reaches a height of 249.6 metres (819 ft).
The Tokyo Imperial Palace (皇居 Kōkyo, literally
"Imperial Residence") is the primary residence of the
Emperor of Japan. It is a large park-like area located in
the Chiyoda ward of Tokyo and contains buildings
including the main palace (宮殿 Kyūden), the private
residences of the Imperial Family, an archive, museums
and administrative offices.
It is built on the site of the old Edo Castle. The total area including the gardens is 3.41 square
kilometres (1.32 sq mi). During the height of the 1980s Japanese property bubble, the palace
grounds were valued by some to be more than the value of all of the real estate in the state of
California.
The exactly tour line will be adjusted according to the situation on Dec 29, 2017.
