Keynote Speaker Introductions

Keynote Speaker I

Prof. PAUL B. BROWN

Department of Forestry and Natural Resources, Purdue University, USA

Prof. PAUL B. BROWN’s research program focuses on aquaculture and aquatic animal nutrition. They

explore aquacultural opportunities for Indiana and other parts of the world and have worked with American

lobsters, spiny lobsters, hybrid striped bass, yellow perch, bluegill, largemouth bass, walleye and tilapia.

Their nutrition work focuses on new diets for established aquaculture industries and development of diets

for emerging industries. They have been working on modified diets for rainbow trout and Atlantic salmon,

as well as tilapia. New diets for yellow perch, hybrid striped bass and largemouth bass have been developed.

Much of our work has been focused on replacing fish meal in diets. The global supply of fish meal has been

at maximum sustainable yield for approximately 8 years, but demand continues increasing. They have been

successful replacing fish meal with soybean meal in diets for yellow perch, and hybrid striped bass and are

currently exploring use in largemouth bass. There is a need within aquaculture specifically and animal

nutrition in general to develop diets rapidly. They are currently exploring use of two new scientific

disciplines to understand nutrient needs and use of ingredients from diets. Combining metabolomics and

proteomics provides us with a more complete view of metabolism. They are also using the combination of

metabolomics and proteomics to understand flows of nutrients through food webs and applying this

approach to both aquaculture and natural settings.

Topic: ―Sustainable Aquaculture: a Long Way to Go and a Short Time to Get There‖

Prof. Paul B. Brown

Purdue University, Indiana, USA

Abstract—Sustainability is a commonly used term applied to fisheries. Maximum sustainable yield (MSY)

has been one of the driving forces in harvest regulations for the past century or so. Sustainability has also

been used in reference to aquaculture, particularly as aquacultural production increased over the past 25+

years. Sustainable aquaculture development was considered as early as 1987-1989 as fisheries harvest

reached MSY. However, the newer definition, or vision, for sustainable development has not been fully

embraced in aquaculture production. At a minimum, sustainability encompasses three spheres,

environmental, economic and sociological, with sustainability occurring at the juncture of all three spheres.

New metrics have been developed that attempt to quantify disparate systems, such as food production

systems, and can be applied to various aquaculture production systems. Initial data developed indicate

feed inputs as one of the least sustainable components of food production systems, including aquaculture.

Dietary ingredients can be characterized by the amount of carbon dioxide (CO2) produced during

production, harvest, processing, storage and distribution. The Global Warming Potential (GWP, kg CO2/mt

product) differs significantly across commonly used dietary ingredients, decreasing significantly as we

move from fish meal (3500), to plant-based ingredients (437), and animal by-product ingredients (68).

Additional quantitative measures of sustainability include abiotic depletion (fossil fuel use, Sb equivalents),

acidification potential (PO4 equivalents), eutrophication potential (PO4 equivalents), human toxicity

potential (1,4-dichlorobenzene equivalents), marine toxicity potential (1,4-dichlorobenzene equivalents)

and cumulative energy potential (MJ). The water footprint, or water demand for food production, is another

quantitative measure that can be incorporated into developing models of sustainability. Preliminary data

indicates that water-based food production systems such as aquaculture demand significantly less water per

unit food production than terrestrial-based food production systems. The global aquaculture community

could benefit from an expanded definition of the term sustainability and application of the developing

quantitative measure of sustainability might identify seafood production systems as desirable for global

economic development goals.

Topic: ―Phthalates Exposure Ans Health Outcomes of Pregnant Woman, Newborn,

Precocious Girl and Adult Men‖



Abstract— Phthalates are added to plastics to make them soft and flexible, to cosmetics as a vehicle for

fragrance, and to many other daily products, such as building materials, children's toys, and medical

devices. Phthalates are not chemically bound to these products and are released continuously into

foodstuffs and the environment. Because phthalates are ubiquitous in daily life, the potential consequences

of human exposure to phthalates have raised concerns in the general population. Phthalates, are

reproductive and developmental toxicants in animal models, and the ability of phthalates to penetrate the

placenta have been reported. Phthalates are considered anti-androgenic endocrine disruptors because of

their possible effect on animal gonads and reproduction. In addition, some studies have reported possible

antagonistic effects of phthalates on the thyroid gland in vivo and thyroid tissue in vitro. However, little is

known about those issues in humans.

In our first study, we found a significant positive correlation only between creatinine adjusted urinary MBP

and amniotic fluid MBP (R2 = 0.156, P < 0.05) in all infants and, only in female infants, a significantly

negative correlation between amniotic fluid MBP, AGD (R = .0.31, P < 0.06), and the anogenital index

adjusted by birth weight (AGI-W) ( R = .0.32, P < 0.05). Although the influence of prenatal di-n-butyl

phthalate (DBP) exposure on the endocrinology and physiology of the fetus is still a puzzle, our data

clearly show that in utero exposure to phthalates in general has anti-androgenic effects on the fetus.

In second study, we found all seven urinary phthalate metabolites in the CPP group were significantly (P <

0.05) higher than in prepubescent controls. Serum kisspeptin-54 levels were higher (P < 0.022) in the CPP

group than controls and were still significantly higher after adjusting for age (P < 0.03). There is a

significant increasing trend (Ptrend < 0.005) between levels of kisspeptin and the stages of puberty, and a

significant positive correlation between kisspeptin-54 and urinary mono-n-butyl phthalate (ng/ml: R2 =

0.251, P < 0.001; mg/g-creatinine: R2 = 0.109, P < 0.024). We found kisspeptin may promote the onset of

puberty in girls who are exposed to a high level of phthalates, especially di-n-butyl phthalate. And then,

The intervention strategies that we set up in this study were effective for reducing exposure to phthalates in

children. Handwashing and drinking fewer beverages from plastic cups were the most effective strategies

for reducing phthalate metabolites in urine, especially MBP and di(2-ethylhexyl) phthalate (DEHP)

metabolites.

In third study, we found an inverse association between urinary levels of MMP, MiBP, MEHP, MEHP%

and serum TT. The inverse associations were also found between urinary levels of MiBP, MBzP, MEHP,

MEHP% and serum fT. Urinary MBzP and MEHP% were negatively associated with a decrease in serum

INSL3. We also observed a strong inverse relationship between MEHP% quartiles and serum TT, fT, the

TT : LH ratio and INSL3. Ssignificantly monotonic trends in semen volume, sperm concentration and

motility were associated with increasing quartiles of INSL3 were found. In adjusted regression models,

increases in urinary phthalate metabolites levels were adversely associated with sperm concentration

(MBzP, MEHP and MEHP%), motility (MBzP and MEHP) and INSL3 (MBzP, MEHP and MEHP%). Our

data suggest that INSL3 secretion, reproductive hormone balance, and sperm production and quality might

be simultaneously adversely affected.

Prof. Hans-Uwe Dahms

Kaohsiung Medical University, Taiwan

Porf. Hans-Uwe Dahms was born in Wilhelmshaven, Germany. He received his PhD and DSc

degrees in Biology from University Oldenburg, Germany. He is currently a Professor at the

Department of Biomedical Science and Environmental Biology in Kaohsiung Medical

University (KMU - Taiwan). His current research is equally concerned about Environmental

and Public health. This includes green technologies to monitor, remediate and sustainably

manage environmental and medical issues in aquatic systems.


- 13 -

Topic: ―Antibiotics and Antibiotic Resistant Microbes in Aquaculture – Sources, Sinks

and Pathways‖



Abstract—More than 5 million cases of hepatitis and more than 250 million cases of gastroenteritis and

respiratory diseases are reported annually worldwide. This indicates that infectious diseases are on the rise.

Reasons for this are an ever increasing world population and the ease of travelling that enhances the risk of

disease spread. An unprecedented rise of antibiotic resistance of most pathogenic microbes and viruses

provides another serious health risk. We show that the aquatic environment and aquaculture within

freshwater, brackish and seawater components provide a serious source of antibiotic resistant pathogens.

Here, some pathogens even get more virulent than in their human host. This way environmental health as a

branch of public health gets unexpected importance with several facets of the natural and man-made

environment that affects human health. Three basic disciplines generally contribute to the area of

environmental health: environmental epidemiology, toxicology, and exposure science. Information from

these three disciplines can be combined to conduct a risk assessment for specific physical, chemical, or

biological hazards. Such risk factors, separate or in combination, determine whether an exposure poses

significant risk to human health. This can in turn be used to develop and implement environmental health

policies that regulate chemical emissions, or impose standards for proper sanitation. This way

environmental health management can become a tool of preventive medicine. Preventive medicine as a

branch of public health attempts to prevent diseases such as infectious diseases, as opposed to disease

treatment. Just as public health focuses on a variety of physical and mental states, so do disease and

disability, which are affected by genetic predisposition, disease agents, life style, and environmental factors.

We will provide examples here from antibiotics and antibiotic resistance of human pathogenic bacteria that

were collected from aquaculture facilities in freshwaters, brackish and coastal waters. These are posing

threats to respective ecosystems and the food and drinking water safety of coastal populations. Possible

solutions to the antibiotics crisis are outlined here and discussed.

Plenary Speaker Introduction

Plenary Speaker I

Assoc. Prof. Win Chaeychomsri

Faculty of Science, Kasetsart University, Thailand

Assoc. Prof. Win Chaeychomsri received a Bachelor‘s Degree in Biology, Master‘s Degree in

Tropical Medicine, and Doctoral Degree in Animal Biotechnology. He has been a lecturer in

Department of Zoology, Faculty of Science, Kasetsart University since 1994. He is an

outstanding lecturer in research and innovation. His current research interests are in the fields

of parasitology, immunology and animal biotechnology. He has authored books, published

more than 100 technical papers in various journals and conference proceedings. He gets 3

petty patents and 2 patents. These petty patents and patents involve the production technology

of freeze-dried crocodile blood that will be used as dietary supplement for health

improvement.

Topic: ―Successful Innovation of Freeze-dried Crocodile Blood and Related Products as

Dietary Supplement‖



Abstract—Among the earliest recorded use of crocodiles in Traditional Chinese Medicine (TCM) was the

application of blood for health care benefits. It has been reported that crocodile blood contains potent

antibacterial and antiviral properties. The Siamese crocodile (Crocodylus siamensis) is one of the medicinal

animal. This species is a freshwater crocodile native to Southeast Asia. The practice of consuming

crocodile blood for improving human health is found in many Asian cultures and traditions. Crocodile

blood capsule, a dietary supplement, is the world and Thailand‘s first crocodile blood product based on

research studies conducted by the Crocodile Research Unit, Department of Zoology, Faculty of Science,

Kasetsart University (KU), Thailand. This product is derived wholly from captive Siamese crocodiles blood,

containing 100% natural ingredients and no artificial preservatives added. Crocodile blood capsule contains

high levels of protein, iron, many minerals and vitamins. The large volume-collecting and freeze-drying

processes of Siamese crocodile blood were designed and developed. These freeze-dried blood products

were packed in capsule, testing for bacterial and heavy metal contamination. The results showed that

freeze-dried crocodile blood products have no bacterial and heavy metal contamination. In collaboration

with private sector, KU has made an effort to enhance clean and safe production processes at the acute,

sub-chronic, and chronic levels, and to study the efficiency of freeze-dried crocodile blood product, which

has subsequently approved by the Thai Food and Drug Administration (Thai FDA), Ministry of Public

Health, as a dietary supplement since 2008. The safety evaluation of freeze-dried crocodile blood was

performed in both sexes of Sprague Dawley rats. Freeze-dried crocodile blood was orally administered for

24 weeks. The blood ingestion had no effect on rat behavior and survival. The hematological values did not

reveal differences between the treated and the control groups. The biochemical values including alkaline

phosphatase (ALP), aspartate transaminase (AST), alanine transaminase (ALT), blood glucose, blood urea

nitrogen (BUN) and albumin were not significantly different among experimental groups throughout the

study time. The results observed in iron-deficient rats demonstrated the efficiency of freeze-dried crocodile

blood in increasing values of hemoglobin and hematocrit within the first 4 weeks of treatment and no

histological changes in intestine, kidney and liver after a 24-week treatment. These data suggest that the

freeze-dried crocodile blood has safety and efficiency in promoting hemoglobin and hematocrit values.

Thus, the freeze-dried crocodile blood can be used as food supplements in anemia patient.

Then, KU has permitted for using intellectual properties and transferred crocodile blood capsule production

technology to private sector under the brand ―Wynn‖ that has received certificate from Thai FDA as No.

13-1-03060-1-0001. The freeze-dried crocodile blood products are available in the market and many

consumers who suffer with anemia, cancer, AIDS and diabetes have told the research team that their health

conditions and problems are improved. Since insulin-like growth factor I (IGF-I) has been found in

Siamese crocodile serum and the ability of IGF-I to reduce fasting blood glucose levels is well recognized.

Recently, the crocodile serum has been developed for the patient with diabetes under the brand name


- 16 -

―Jakhae Thai‖. In addition, the guidelines for collection of large volumes of blood from crocodile have

been developed with the goal to ensure the product quality, and also safety of the animals. Therefore, these

data demonstrate a good case in value-added crocodile blood product development. Most importantly, a

focus on quality management system would add value and help expand both local and export markets.

Venkatakrishnan, S Sudhakar and P Suriyanarayanan

Tata Sons Group Technology and Innovation Office, India

Abstract—Despite having one of the largest arable and irrigated land India ranks poorly in

farm productivity due to factors including lack of market- appropriate technologies, use of

non-standard practices, and growing shortage and cost of farm labor. This paper discusses

research and development of UAV-based low-volume spraying techniques, which have been

successfully validated on multiple crops, and presents key results including efficacy,

phytotoxicity, efficiency, and crop-specific optimizations required to achieve industry

benchmarks. Currently, commercial field pilots are underway to validate market-appropriate

business model(s) to offer UAV aerial spraying agri-services.

Economics of Big Data in U.S. Agriculture

Mitchell Morehart

Authoritative Analytics, USA

Abstract—Are the economic benefits to producers and the agricultural sector from Big Data, illusionary

or real? The phenomenon of Big Data in U.S. agriculture encompasses diverse and massive volumes of

data that can be captured, analyzed and used for decision-making by a variety of stakeholders. The

landscape of stakeholders exhibits an interesting intersection between powerful technology companies,

venture capitalists, and often small start-ups and new entrants. The agriculture sector is well placed to

leverage big-data technology and many companies are contributing to its success. Every aspect of crop and

animal production will soon have data capture capabilities. This talk will highlight the historical

development of Big Data in agriculture. It will examine two primary vessels for economic gain;

improvements in supply chain linkages and improvements in on-farm production practices. Supply chain

traceability can reduce exposure to hazardous foods and reduce quality deterioration. Moreover, a more

systematic alignment along the supply chain from input supplier and manufacturing to food retailer has the

potential to increase efficiency through better product flow scheduling and inventory management.

Inefficiencies in planting, harvesting, water use, transportation, as well as uncertainty about the weather,

pests, consumer demand and other intangibles can be greatly reduced by these emerging technologies. The

role of software and how Big Data is being used to provide predictive insights in farming operations, drive

real-time operational decisions, and redesign agricultural production processes will be discussed. Data

privacy and ownership have been topics of discussion in precision agriculture since the first global

positioning system (GPS) began recording data geospatially more than 25 years ago. The line between

what data and information farmers are willing to share and a company is allowed to use will keep shifting.

At the same time, there are several public institutions that publish open data, under the condition that the

privacy of persons must be guaranteed. Clearly, there are no easy solutions. Growers need to be

circumspect in the management and protection of their data and information and be knowledgeable about

the purposes and practices of other individuals and companies with whom they are sharing data and

information.

Fish Allergenicity Modulation towards the Production of a Low Allergen Farmed Fish; a

Proteomics Approach

Pedro M L Rodrigues, Denise Schrama and Cláudia Raposo

University of Algarve, Portugal

Abstract—Food allergies are a significant public health concern throughout the world. Fish is

a food product increasingly consumed worldwide due to its high nutritional value and healthy

meat. Unfortunately, like many food sources, fish can cause adverse immune-mediate

reactions in some individuals. This allergic reaction to food, affects 1-3% of the population

and about 4-6% of children. The main fish allergen is β-parvalbumin; a small and highly

stable muscle protein. Fish parvalbumins are highly conserved proteins, which are binding

bivalent ions, calcium or magnesium. In fish-allergic patients, specific IgE cross-react mostly

with parvalbumins from different fish, especially when recognizing highly identical protein

regions involved in the ion binding. Other fish allergens have been identified as well - such

as enolases, aldolases or fish gelatin - but their importance has been only shown for a limited

number of fish species. Currently, there is no cure available for fish allergies with the clinical

management of fish allergy solely relying on a strict avoidance diet. Modulation of fish

allergenicity towards the production of a low allergen farmed fish was firstly attempted by

our group. This has been done with specifically designed fish diets, enriched in components

and small changes introduced in the fish farming process that target the expression or

inactivation of the main fish allergen; parvalbumin. Proteomics is the chosen technique to

access fish allergens characterization and expression in muscle while IgE assays to confirm

the lower allergenic potential of this fish are conducted in patients with history of fish

allergies.

Review of Environmental Sustainability Assessments of Aquaculture Systems: Main Findings

and Outlook

Florence Alexia Bohnes, Michael Zwicky Hauschild, Jørgen Schlundt and Alexis Laurent

Technical University of Denmark, Denmark

Abstract—Aquaculture has been growing quickly during the last decades and, albeit often

regarded as sustainable by nature, this sector remains associated with several environmental

impacts (e.g. aquatic eutrophication, ecotoxicity impacts in local ecosystems). To assess

environmental sustainability of food production systems, one of the most commonly used

tools is life cycle assessment (LCA), which quantifies the impacts of a system along its

whole life cycle. Over the past decades, LCA has been applied to aquaculture systems, but

what are the lessons we learn from them? To address this question, we performed an

unprecedentedly comprehensive critical review encompassing 65 LCA studies of aquaculture

systems published in peer-reviewed journals. We conducted a statistical meta-analysis of the

results, and performed comparative analyses of the fish farms and practices, accounting for

differences in intensity, technology, feed conversion ratio (FCR), and types of farmed

species. Overall, we found that FCR, the species and the technology have a significant

influence on the environmental impacts per produced output. The intensification of the

aquaculture systems is usually associated with environmental burden-shifting from local to

global impacts. Polyculture is a promising candidate for more sustainable aquaculture

systems, especially integrated agriculture-aquaculture and aquaponics. Therefore, in the quest

for more environmental-friendly aquaculture systems, we recommend to (1) focus on

reducing the FCR and choose environmental-friendly diets (e.g. replacing fish meal and fish

oil ingredients by crop ingredients); and (2) implement systems such as closed-systems or

polyculture, that allow efficient management of nutrients without creating burden-shifting

with energy demand.

College of Economics and Management, Shanghai Ocean University, Shanghai, China

Abstract—Based on the survey data from Shandong and Liaoning Province, this paper

investigates the factors that influencing the formal loan demand and availability of

aquaculture farmers in China. The results show that: (1) Culture area and technical level have

the positive impacts on the formal loan demand. (2)Technical level and the number of bank

visit for loans can have the positive impact on the formal loan availability. But the scale of

loans and the distance to financial institutions have a negative impact on the formal loan

availability. In addition, Liaoning Province loan availability is significantly higher than that

in Shandong Province. (3) Culture area and technical level have positive influence on both

applied and approved loan amounts. (4) The applied and approved loan amounts for factory

culture are both significantly higher than those of pond culture.

Abstract—Indonesia is a country rich in various local fruits that are not too familiar among

the people, one of them is Ciplukan. Ciplukan or better known as a Cape Goose Berry, is

―super fruit‖ because it contain of many beneficial compunds such as flavonoids, alkaloids,

terpen, ascorbic acid and karetonoid. Carotene and lycopene are compounds that are easily

affected by temperature. The objective this study is to determine the effect of Ciplukan

storage treatment on the content of beta carotene and lycopene. The treatments were two

storage temperature (4°C and 10°C [room temperature]) and packaging (package and

un-package). The fruit with room temperature and packaging in plastic storage, showed

significantly higher beta carotene and lycopene content than fruit that storage in 4°C and

without packaging.

Asian Institute of Technology, Thailand

Abstract—In the present study, the green technological approach – ultrasonic assisted

extraction (UAE) was employed for the extraction of anthocyanins, total phenolic compounds

(TPC) and their antioxidant activities from black glutinous rice. The effects of ethanol

concentration, amplitude and time were investigated using Box – Behnken design and

extraction conditions were optimized by using response surface methodology (RSM). The

optimal ethanol concentration, extraction time and amplitude were 65%, 15 min and 100%

respectively. The maximum anthocyanin content, TPC and antioxidant activity were found as

47.45 mg cyn-3-glucosidase/gram fresh weight ml, 83.07mg GAE/ g, 99.59 % for DPPH and

0.19 mg AAE/g. Statistically, only concentration of ethanol indicated significant effect on the

extraction. The ethanol concentration of 65% gave high yield of anthocyanins, TPC and

antioxidant activities. In the case of amplitude and time, there was no significant difference

compared to ethanol concentration. This study to a certain extent revealed important bioactive

properties of black glutinous rice. i.e, the high antioxidant activity, presence of anthocyanins

and TPC.

Microcrustacean Moina macrocopa: An Important Feed for Aquaculture and a Potential

Bioindicator for Heavy Metals Contamination in Aquatic Environments

Chanya Phromchaloem, Amonrujee Nakphlaiphan and Thanit Pewnim

Department of Chemistry, Faculty of Science, Silpakorn University, Thailand

Abstract—Water flea Moina macrocopa is a microcrustacean found in abundant in tropical

countries such as Thailand. The micro crustacean has been used extensively in rearing fish

fingerlings, both ornamental fishes and edible fishes. While the aquaculture industry of

Siamese fighting fish (Betta splendens) relies heavily on the cultivation and use of Moina

macrocopa, practically as the only feed for the fish, the raising of fresh water fish such as

catfish and tilapia use Moina macrocopa to feed the fish fingerlings until they reach a size

that can feed on pellets. This paper surveys the production of the microcrustacean and its

successful use in aquaculture in Thailand, while at the same time investigating the potential

use of this microcrustacean as a bioindicator for heavy metals contamination. Laboratory

investigation found that treating Moina macrocopa with cadmium at a concentration of 160

µg L-1

for 48 h resulted in cell nuclei damages as judged by single cell gel electrophoresis or

the Comet Assay. It was also found through gel filtration experiment and the SDS-PAGE

analysis that cadmium induced the synthesis of a cadmium binding protein having a

molecular mass around 50-55 kDa. A comparative study on cadmium toxicity was also

carried out with Drosophila melanogaster larvae. It was found that the heavy metal induced

the synthesis of cysteine-rich proteins in the larvae of the insect. It can be concluded that

while Moina macrocopa is useful as a live feed in aquaculture, the microcrustacean has a

potential for use as a bioindicator for heavy metals contamination in aquatic environments.

Trehalose Association for Drought Tolerance in Wheat (Triticum aestivum L.) Germplasm

through SSR Markers

Muhammad J. Iqbal, Naureen Shams and Amer Jamil

COMSATS Institute of Information Technology, Defence Road, Lahore, Pakistan.

Abstract—Drought, one of the abiotic stresses, substantially hampers the crop productivities

worldwide. For mitigating the stress, in plant cell various biochemical mechanisms including

the synthesis of trehalose which is a known intrinsic response of drought tolerant plant

species. Cultivated hexaploid wheat (Triticum aestivum L.) is one of the most important

staple food crops in many countries including India and Pakistan. It often experiences

drought stress, and would be much more devastating under the upcoming new challenge of

climate change. In the present study, a total of 66 diverse wheat genotypes including cultivars

were grown under well watered and limited water conditions. DNA fingerprinting of wheat

germplasm of the selected genotypes was done on the basis of polymorphism using 45 SSR

primer pairs and tested for polymorphism among different genotypes viz Local Genotype,

Mapping Population, Synthetic and NIBGE. The dendrogram results have shown the

genotype association with the levels of trehalose during induced drought stress. The

relationship between pattern of drought responsive biochemical attributes and DNA markers

in the selected wheat genotypes was established with a recommendation to select drought

tolerant genotypes for sowing in drought affected areas.

Cultivars

Wisnu Eko Murdiono, Koesriharti and Palupi Wulandari

Brawijaya University, Indonesia

Abstract—Red Lettuce (Lactuca sativa) cultivars, such as Red Rapid and Lollo Rossa, play

an important factor in order to increase Indonesia's vegetable production to meet the domestic

demand. The use of biological fertilizers, such as Plant Growth Promoting Rhizobacteria

(PGPR) are another important factor to increase production in sustained agricultural systems.

The purpose of this experiment was to study the effect of PGPR applied on the growth and

yield of two red lettuce cultivars. This experiment was conducted in Dadaprejo Village,

Junrejo District, Batu in July - August 2017. This was a factorial experiment arranged in

Completely Randomized Block Design which consisted of 2 factors. The first factor was two

red lettuce cultivars consisted of Red Rapid (V1) and Lollo Rossa (V2). The second factor

was a PGPR dosage consisted of 6 levels : without PGPR (P0), 100 ml PGPR (P1), 150 ml

PGPR (P2), 200 ml PGPR (P3), 250 ml PGPR (P4) and 300 ml PGPR (P5 ). The observed

growth parameters were plant height and number of leaves at 10, 20, 30 and 40 days after

transplanting. Observations made during harvest were root length and weight, total fresh

weight and also consumable weight. The result showed that there were interactions between

PGPR application and red lettuce cultivars on all harvest parameters. On both red lettuce

cultivars observed, application of 200 ml PGPR affected on higher root length and weight,

while applying 300 ml of PGPR produced higher consumable weight and highest total fresh

weight than any other dosage. Each PGPR dosage combined with Red Rapid produced higher

root and total fresh weight than Lollo Rossa.

Telemetric Lactic Acid Monitoring System for Real-time Assessment of Exercise Intensity

Keigo Enomoto, Takahiro Kurose and Hiroyuki Kudo

Meiji University Graduate School, Japan

Abstract—A telemetric lactic acid(LA) monitoring system was developed and telemetry of

sweat LA of jogging subject was conducted for the first time. Non-invasive assessment of

blood LA is strongly requested in a wide variety offields such as conditioning and training in

sports, care in medical facilities and triage at disaster site. Previously, we reported a

microfluidic bio-sensing system for continuous LA monitoring. Although the performance

was satisfactory, it was still difficult to utilize the system to the subject freely moves around

because of large equipment (syringe pumps, electrochemical analyzer and sensing element) as

well as presence of tubes for liquid supply and electric wiring. In this study, (1)a micro

fabricated biosensor with lactate oxidase-modified platinum electrode, (2) piezoelectric micro

pumps (25mm x 25mm x 4.8mm)and (3)miniaturized potentiostat which is capable of

Bluetooth interface were newly employed for the purpose of constructing a portable LA

monitoring system. Our system measures sweat LA by attaching a flexible sampling device

with a micro flow channel(1 mm x 30 mm x 0.2 mm) on the surface of the skin and

transporting whole secretions to the biosensor using a continuous career flow of phosphate

buffer saline. The biosensor measures LA as production of hydrogen peroxide produced in

enzymatic conversion of LA to pyruvic acid. Sufficient sensitivity (LA :53.14 nA・mM-1)

and response time(t95:8.3s)was obtained. In order to keep sufficient suction pressure even if

the position or angle of the system changed due to exercise, two piezoelectric micro

pumps(25mm x 25mm x 4.8mm)were connected in series. This enabled sweat lactate

monitoring under the conditions involving free movement.

Under the approval of ethical committee of Meiji University, the LA monitoring system was

utilized in wireless sweat LA monitoring under the different sweating conditions (sweating by

rising ambient temperature and sweating by jogging).As a result, secretion of lactic acid from

the subject moving around was successfully measured continuously and increased by 3.6

folds after 20 minutes jogging workout. Temporal changes of sweat LA correlated with the

kinetics of blood LA rather than sweat rate in both cases. Further characteristics of the

wireless LA monitoring system, results of sweat LA monitoring and possible applications will

be presented in detail at the conference.

Taiwan

Abstract—Direct-write printing of cells within bioinks presents an opportunity for in vitro

modeling and regenerative medicine. The structure and function of the human nervous system

are altered in 3D when compared with 2D. To investigate directly the influence of 3D

conditions which may be beneficial for cultivation and proliferation of human neural

SH-SY-5Y cell line, the 3D Bioprinter developed at the CELLINK INKREDIBLE was used.

3D Bioprinter allows the creation of a unique environment of low shear force, high-mass

transfer and enables 3) cell culture of dissimilar cell types. The results show that 3D

conditions using an 3D Bioprinter would induce the expression of intracellular mitochondrial

genes, including PGC1(PPAR coactivator 1), nuclear respiratory factors 1 and 2 (NRF1 and

NRF2) and mitochondrial transcription factor A (Tfam) were all significantly increased at 5

day after the onset of 3D. Accordingly and importantly, the ATP level and amount of

mitochondrial mass were also increased. These results suggest that exposure to 3D conditions

using an 3D Bioprinter would increase mitochondrial function. In addition, the 3D Bioprinter

would support cells growth, which may have the potential for cell replacement therapy in

neurological disorders. The 3D conditions will promote investigation of human neuronal

development, function, and disease, and may be adjustable for engineering 3D brain.

Abstract—Water environment suitability evaluation is a prominent requirement to determine

the success rate of sustainable aquaculture business in coastal waters. This study aims to

evaluate the site of floating net cages which already exist in Lampung Bay using water

environment site suitability maps and interview data. Physical water parameter suitability

maps for floating net cage cultivation are generated through spatial modeling of depth, sea

surface temperature, water clarity, suspended solids, salinity, chlorophyll-α, and pH

parameters. All data are combined by using weighted overlay in GIS environment. The result

shows that the development of floating net cages around Sariringgung Beach has good

suitability level whereas Lampung Bay do not meet the suitable class criteria of depth, surface

temperature, and clarity parameters. Disparity on land cover conditions and the understanding

of floating net cage cultivation among the farmers on both sites are the factors that make those

different level of suitability classes.

Exploring a New Way to Create Pectin Hydrogels

Havazelet Bianco-Peled, Irit Ventura and Lena Neufeld

Technion Israel Institute of Technology, Israel

Abstract—Pectin is a complex group of food heteropolysaccharides found mainly in primary

cell walls and middle lamella of most plants. Commercially, pectin is mostly produced from

citrus peel or apple pomace, both by-products of juice production. Pectin is widely used in

the food industry as a texturizer or stabilizer. In addition, applications in the area of

pharmaceutical and biomedical engineering have recently emerged.

Many functional attributes of pectin are based on its ability to form gels. Traditionally, high

methylester (HM) pectin gels are fabricated in the presence of sugars and an acidic

environment, whereas low methylester (LM) pectin gels are prepared in the presence of

divalent ions such as calcium.

It has been recently discovered that hot solutions containing pectin and chitosan demonstrate

gelation occurring upon cooling to room temperature. In our study we characterize the

resulting hydrogels in term of swelling, mechanical properties, viscosity and rheology. Further,

we explore the origin of this gelation using small angle X-ray scattering (SAXS). Modeling

SAXS patterns revealed rigid rod conformation in chitosan solutions, whereas pectin formed a

self-avoiding chain. In addition, nanometric aggregates were detected in pectin solutions.

Pectin and chitosan in mixed solutions adopted a similar semiflexible conformation. The only

sample that created a visually stable gel displayed a different pattern, characteristic to

polymers gels. Manipulating the composition by adding urea and salts highlighted the

important role of hydrogen bonding, which governs the gelation mechanism.

Abstract—Iran country has located on arid/semiarid belt of globe, and because of climate change

impacts, drought has been occurred frequently during last two decades in this country particularly at

late growing season on cereal fields. Consequently, wheat cultivars with less water requirement in

spring and high efficiency with acceptable grain yield are cardinal points on wheat breeding programs

in such an arid part of world. Eight recent-released bread-wheat cultivars: (Rijaw, Karim, Parsi,

Sivand, Pishgam, Sirvan, Oroom & Zaree) along with three superior bread wheat lines (Cross of

Sabalan, Cross of Alborz & DN-11) were compared with two local check cultivars (Sardari & Pishtaz).

Data were analyzed as a Combined Analysis experiment at four trial areas, based on Randomized

Complete Block Design (RCBD) with three replicates on two Agricultural Research Stations

(Islamabad and Sararood) at two continues cropping cycles in Kermanshah province of Iran. Trial

areas were run on: rainfed condition; two times complementary irrigation at grain filling stage on

rainfed situation; terminal drought stress as irrigation cut treatment regime done from boot stage and

continues to physiological maturity stage, and finally, full irrigation situation as control. Based on

two years trial combined results, two complementary irrigation applications (average grain yield was

2541 kg/ha) caused a significant increase on grain yield of considered genotypes (+115%) in general,

compared to rainfed condition (average grain yield was 1182 kg/ha); best response among genotypes

to couple complimentary irrigation was belonging to Sivand cv. and Pishgam cv. by three time

increases in grain yield. Terminal drought stress - with 3861 kg/ha as average grain yield - caused to

40% decrease on grain yield in general in comparison to full irrigation treatment (average grain yield

was 6482 kg/ha), although, Sivand, Parsi and Karim lost about 50% of their grain yield under terminal

drought stress. Terminal drought stress condition was better than double complimentary irrigation

because of 52% more production on grain yield. As the summarized results: Sirvan cv. produced the

most grain yield at normal condition; Pishgam cv. produced the most grain yield at terminal drought

stress situation; Sivand cv. produced the most grain yield at complementary irrigation case, and finally,

Zaree cv. produced the most grain yield at rainfed site in comparison with other genotypes.

Abstract—Indonesia is a major location for artisanal and small-scale gold mining (ASGM)

activities in which large amount of mercury is used to extract gold from ore and the mercury

used is then released to environment. In this study, the mercury in the soils, tailings, sediment,

and waste water was investigated, and the potential of sisal (Agave sisalana) as an economic

fiber plant for phytoremediation of the mercury contaminated soil was estimated around the

ASGM area in West Sumbawa, West Nusa Tenggara, Indonesia. The results showed that the

average concentration of total mercury in the yard soil of ASGM was 41.1 mg kg-1 (about 3

times of the environmental threshold limits of Japan), ranged from 0.25 to 226 mg kg-1. Over

60% of the sampling sites exceeded the environmental threshold limit of Japan. Sisal had

average mercury concentrations of 2.1 mg kg-1 in the leaves, and 14.7 mg kg-1 in roots. It

was estimated that sisal could had an annual phytoremediation potential of mercury ranged

from 21,00 to 880,000 mg ha-1. This study suggested sisal could be a suitable economic fiber

crop for soil contamination of mercury.(This work was supported by JSPS KAKENHI No.

Effects of Histidine, Threonine and Tryptophan Supplementation on the Performance of

Gilthead Seabream Using 2D-DIGE.

Denise Schrama, Rita Colen, Sofia Engrola, Tomé Silva, Pedro M.L. Rodrigues

University of Algarve, Portugal

Abstract—Human fish consumption is continuously growing and aquaculture production

costs need to be minimized, while keeping optimal growth and fish health. Plant-based

protein ingredients are an alternative for fish diets but may influence growth and stress due to

imbalanced amino acids profiles. Evaluation of the functional effect of diet supplementation

with three amino acids, like histidine: involved in biochemical changes which occur during

inflammation; threonine: involved in the immune system response, and tryptophan: involved

in stress and inflammatory responses will be performed using differential proteomics.

Juvenile gilthead seabream were fed with three diets, which were formulated based on

estimated requirements. Diet 1 had 0% of the three amino acids (histidine, threonine and

tryptophan), diet 2 had 1.1% (w/w) of supplementation and diet 3 was supplemented with

1.5% (w/w). Fish were fed twice a day, ad libitum and maintained in natural flow-through

seawater and artificial aeration (dissolved oxygen above 5 mg L-1). After 2 weeks fish were

lethally anesthetized with 2-phenoxyethanol, liver was collected and kept at -80ºC for further

analyses. Proteins were extracted using a DIGE buffer and quantified by the Bradford

method. Proteins were separated using 2D-DIGE on 24 cm drystrips with pH 4-7. Gels were

analyzed using SameSpots software and 19 spots showed significant difference after

statistical analysis (ANOVA, p<0.05) between the diets. Differentially expressed proteins

were sequenced using mass spectrometry. Identified proteins were related to protein transport

upregulated in diet 2 (1.1% supplementation with histidine, threonine and tryptophan),

showing that these amino acids might influence the functional state of gilthead seabream.

Atypical Furunculosis Caused by Aeromonas salmonicida subsp. masoucida Causes Mortality

in Farmed Korean Rockfish (Sebastes schlegelii)


College of Fisheries Science, Pukyong National University, Republic of Korea

Abstract—Atypical Aeromonas salmonicida (RFAS1, 2, 3) were first isolated from diseased

rockfish in fish farms, Geomundo. This slow growing and non-pigmented pathogen caused

mortalities in rockfish farms from December to May. Typical symptoms of the diseased fish

were ulcer lesions over body surface, hamorrhages in gills, eyes and intestine, and swollen

spleen and kidney. The isolates were used for exmination of phenotypic and genotypic

characteristics, challenge test, and survival ability in rockfish serum. A reference strain, A.

salmonicida subsp. masoucida (KCCM 40239), originally isolated from rainbow trout, was

used for comparison. Biochemical characteristics of the isolates and the reference strain were

very similar with some different profiles, such as fermentation of saccharose and amygdalin.

LD50 values of RFAS1 strain were 1.5ⅹ 105.25 and 1.5 ⅹ 106.4 cfu fish-1, challenged by

i.p. and i.m., respectively. Five house-keeping genes (16S rRNA, gyrB, rpoD, dnaJ and recA)

of RFAS1-3 showed the 3 isolates were most closely related to A. salmonicida, but could not

be identified at a subspecies level. According to analysis of vapA gene, encoding A-layer

protein, RFAS 1-3 strains were most closely related to A. salmonicida subsp. masoucida.

However, only RFAS1-3 showed hemolytic activity against rockfish erythrocytes and were

able to survive in rockfish serum but cells of KCCM 40239 decreased rapidly and killed after

12 hours of incubation in the serum. Therefore, newly isolated atypical A. salmonicida are

pathogenic to rockfish, which is the first case of the species isolation from marine fish in

Korea.

Distribution of CD83+ Cell of Olive Flounder (Paralichthys olivaceus): Gene Expression

after Viral Haemorrhagic Septicaemia Virus (VHSV) induced Infection in Fish


College of Marine Science, Gyeongsang National University, Republic of Korea

Abstract—In 1999, VHSV was first isolated from free-living Japanese flounder. Since then,

which has become one of the most serious diseases among farmed fish species. After viral

infection, dendritic cells (DC) drive the activation and differentiation of T-cell to acquire

effector functions. DCs are sentinel immune cells that play a central role for pathogen

invasion including viral and bacterial infection. Only on DC can show stable surface

expression of CD83 and that gene was describe well as maker of mature DC. We identified

olive flounder CD83 and polyclonal antibody was developed against this gene. Further

investigation, expression analysis after viral infection and DC distribution analysis were

carry out on peripheral blood leukocytes (PBLs) and tissue of olive flounder. OfCD83 gene

up-regulated in liver, spleen, head kidney and intestine after VHSV infection. OfCD83+

signal detected in liver sinusoid, follicular dendritic cells of spleen, kidney, lamina propria of

intestine and second lamellae of gill in healthy olive flounder. Our findings contribute to

understanding the teleost DC mediated immune response.

Numerical Analysis according to Evaporator Type

Dae Yeong Kim, Moon Ki Kim and Hong Sun Yun

Research and Development Institute, Daesung-Maref CO. LTD., Korea

Abstract—An important part of the refrigeration system used in agricultural product stroage is

evaporators. It is an important device to determine the quality of agricultural products

according to evaporator performance.

Through numerical analysis of the evaporator, it is analyzed that the performance varies with

the type of evaporator. Numerical analysis of the evaporator was performed using the EES

program. The verification of the calculation was verified by comparing with the performance

of the product. The numerical analysis of the evaporator capacity was use to calculate the

evaporator capacity by using the heat transfer coefficient of refrigerant, tube wall, and air. It

compared the numerical analysis of the evaporator capacity and the five my company

products, and showed about 10% error rates. The tendency was analysed according to fins

space, mass flow, heat exchange coil length and air flow. The fin space was changed from

1mm to 20mm in increments of 0.5mm. When the fins are narrow, the air flow is reduced to

lower heat exchange efficiency, and vice versa, resulting in decreased air flow compared to

the refrigerant flow rate, thereby reducing the efficiency of the heat exchanger. The length of

the heat exchanger changed from 500mm to 2400mm in increments of 50mm. As the length

of the heat exchanger increases, the piping friction and the refrigerant temperature rise.

Consequently, the difference in temperature between the refrigerant and the air temperature

decreases, thereby reducing the efficiency of the heat exchanger. The air flow of the changed

from 20CMM to 400CMM in increments of 10CMM. When the air flow rate is higher than a

certain level, the air flow velocity is increased and the heat exchanger efficiency tends to be

lowered. The refrigerant mass flow rate was changed from 3g/sec to 174g/sec in increments of

4.5g/sec. As the flow rate of the refrigerant mass increases it tends to increase proportionately.

However, refrigerant mass flow rate above a certain level, the refrigerant mass flow rate is

larger than the air flow rate, thereby lowering the heat exchange efficiency.

In conclusion, the optimum design of the evaporator depends on the size, load, the evaporator

must be designed in consideration of the fin spacing, heat exchanger coil length, air flow, and

refrigerant mass flow rate.

Phytase Production by Grifola Frondosa and Its Application in Inositol-enriched Solid-state

Fermentation brown Rice

Shih-Jeng Huang, Chieh-Han Chen, Zih-You Chen, Zhi-Wei Lin and Shu-Yao Tsai

Department of Food Nutrition and Health Biotechnology, Asia University, Taichung, Taiwan,

ROC

Abstract—Mushrooms can produce a variety of enzymes and therefore have many

biotransformation capacities. Phytic acid is a ubiquitous anti-nutritional factor in many plant

foods, which results in a lack phytase for monogastric animals (humans, pigs, and chickens)

reducing digestion and absorption of metal elements, protein, starch and lipid. Phytase is

used commercially to maximize phytic acid degradation and to increase inositol in animals.

We analyzed the phytase activity based on 24 kinds of mushroom fruiting bodies. The results

showed G. frondosa has higher phytase activity (1.85 µmol/min of tissue). In liquid-state

fermentation, G. frondosa has high phytase activity of 2.46 µmol/min at 12th grown day. The

increase of inositol content in G. frondosa solid-state fermentation brown rice was 176-fold

as compared to that in the un-fermentation controls. The inositol-enriched G.

frondosa-fermented brown rice demonstrated greater antioxidant properties and contained the

highest antioxidant components than un-fermented brown rice.

Effect of Lateral Displacement of the Papillary Muscles on Functional Mitral Regurgitation

Woojae Hong, Soohwan Jeong and Hyunggun Kim

Sungkyunkwan University, Suwon, Republic of Korea

Abstract—BACKGROUND: Functional mitral regurgitation (FMR) develops when regional or global

enlargement of the left ventricle occurs, which is frequently associated with anomalous displacement

of the papillary muscles (PM). Although studies have identified the mechanisms of abnormal mitral

valve (MV) leaflet tenting leading to MR, the relationship between PM displacement following left

ventricular chamber dilatation and the severity of FMR still remains unclear. In this study, we

investigated the pathophysiologic mechanism of FMR from a biomechanical perspective utilizing our

computational MV evaluation protocol.

METHODS: A computational MV model having no pathologic characteristics at end diastole was

created using our previously developed virtual MV modeling protocol. Three different types of PM

displacement to mimic the pathology of FMR were simulated by altering the normal PM locations

based on previous clinical studies on measurement of PM displacement. The first pathologic MV

model was subjected to PM displacement of 8 mm toward the lateral direction. The second pathologic

MV model was designed with apical PM displacement of 1 mm. For the third pathologic MV model,

both lateral and apical PM displacements were incorporated. A physiologic transvalvular pressure

gradient across the complete cardiac cycle was applied to the ventricular side of the mitral leaflets in

each MV model. Computational dynamic simulations of MV function were performed for these MV

models and compared one another.

RESULTS: The normal MV clearly demonstrated full leaflet coaptation at peak systole. The

pathologic MV having lateral PM displacement revealed abnormal radial elongation of the P2 scallop,

reduced leaflet coaptation, and increased leaflet stress distribution in the P2 scallop. There was little

difference in leaflet coaptation and leaflet stress distribution between the normal MV and the MV with

apical PM displacement. When the PM locations were displaced to both lateral and apical directions,

an excessive stretching of the leaflets was associated with markedly reduced leaflet coaptation and

large stress distribution in the P2 scallop.

CONCLUSIONS: In this study, we demonstrated the effect of lateral and apical PM displacement on

the occurrence and severity of FMR. When both lateral and apical PM displacements occurred, a

substantial lack of leaflet coaptation was observed. Simulation-based biomechanical evaluation of

MV pathology related to left ventricular chamber dilatation provides an excellent tool to better

understand the pathophysiologic mechanism of FMR.

Tissue Distribution of Copper in Mice Following Exposure to Arsenic in Drinking Water

Younghee Kim, Jiguk Kim and Kisok Kim

Keimyung University, Republic of Korea

Abstract—Arsenic (As) is a common and conspicuous toxicant. The tissue distribution and

correlation between tissues for copper was assessed in male C57Bl/6 mice exposed to 0, 50,

500, or 5000 ppb arsenic in their drinking water for 3 weeks. The copper concentration in

blood increased linearly with increasing arsenic doses, whereas the copper concentration in

liver or kidney decreased linearly with respect to the dose applied. These results indicate that

there may be tissue difference in the disturbed levels of copper in the mice blood, liver, and

kidney by subchronic exposure to arsenic in drinking water.

How to Predict Gait Speed and Ground Reaction Forces using Foot Pressure Sensors

Chang-Hyun Choi, Sun-Ok Chung and Joung Hwan Mun

Sungkyunkwan University, Korea

Abstract—The aim of this study was to predict ground reaction forces and gait speed

according to the plantar pressure data which obtained by insole type measurement device.

To predict gait speed and ground reaction forces of foot, the artificial neural network was

used in developing the models while in stance phase, swing phase for gait speed and nonlinear

models to obtain 3-axis of ground reaction moment in sagittal (GRFs), frontal (GRFF),

transverse (GRFT) and reaction ground force in medial-lateral (GRFML), anteriorposterior

(GRFAP), and vertical (GRFV) due to the fact that the vertical force can be obtainable from

plantar pressure data. There were three input variables of the prediction model of ground

reaction forces: accumulated plantar pressure which refers to time, the

pattern of center of pressure, and measured data of the opposite foot. These variables had

played significant role in improvement of the prediction performance of the nonlinear models.

To proceed the study, 80 young adult participants were gathered and performed normal

walking motions. All subjects were wearing portable insole-type measurement device which

composed of 99 pressure sensors. The predicted results of gait speed and ground reaction

forces were validated with actual data from a human motion capturing system (VICON 460)

and verified with five-fold cross-validation method. From the results, the correlation

coefficients showed high value for three different gait speeds (0.98, 0.97, and 0.95) and

showed high prediction accuracy for both prediction models in accumulated plantar pressure

and plantar pressure in opposed foot (r = 0.88-0.98) and accumulated plantar pressure and

center of pressure patterns (r = 0.91-0.99). Those findings were proposed that the methods in

this study are expected to be used to help in predicting various kinds of diseases and limited

spatial motions in ground reaction forces measurement process.

Near-infrared Spectroscopy Can be Used in Evaluation of Flesh Texture (Crunchiness) and

Water Content (Juiciness) of Apple Fruit

Jian-Zhi Chen and Sheng-Hao Tseng

National Cheng-Kung University, Taiwan

Abstract—Noninvasive optical methods have been widely applied to noninvasively

characterize the properties of turbid samples through measurements of photon-matter

interaction phenomena such as fluorescence or reflectance. Among various optical methods,

diffuse reflectance spectroscopy (DRS) has been demonstrated to be useful in apple quality

monitoring. For example, Cubeddu et al. employed a femto-second pulse laser source and

measured the diffuse reflectance containing pulse broadening effect caused by apples to

derive the absorption and scattering properties of apples. Durkin et al. illuminated apples

with striped patterns and record the diffuse reflectance images at various spatial frequencies

to determine the absorption and reduced scattering spectra of apples. Although DRS systems

have been used to retrieve the optical spectra of apples, the connection between the spectra

and the physical characteristics such as flesh texture and water content of apples has not been

established. In this study, we show that the near-infrared optical properties of apples

recovered from our frequency domain DRS system at the source-to-detector separation (SDS)

of 1 mm can reflect the properties of juiciness and crunchiness of apples. The system has the

potential for efficient and noninvasive grading the apples and other fruits.

Study on Water Quality in Tributaries of the Han River in Seoul

Sang-Hoon Lee and Hong-Kyu Ahn

Korea Institute of Civil Engineering and Building Technology, Korea

Abstract—The Seoul Metropolitan Government has performed a project that restores physical

shapes and ecological functions in damaged tributaries in Seoul continuously since 2000s. As

a result, ecological restoration in tributaries of the Han River has been conducted and stream

environments have changed variously.

Although water quality in streams has been improved overall, some streams have the

following problems despite of the ecological restoration project of tributaries.

First, the grade of water quality is still low even after ecological restoration. This was because

the project focused only on the restoration of a site of human living around the streams such

as maintenance of low flow revetment and high-water-level land by the river but the

contaminated sediments on the river bottom were not treated well thereby making a

continuous flow of contaminants into the streams and lowering the water quality grade.

Second, an increase in the coliform group was verified. For streams whose water quality has

improved, their mean water quality grade was Grade II (pH:6.5~8.5, BOD:≦3 mg/L, COD:≦

5 mg/L, TOC:≦4 mg/L, SS:≦25 mg/L, DO:≧5 mg/L, TP:≦0.1 mg/L, total Coliforms:≦

5,000MPN/100mL, Fecal coliforms:≦1,000MPN/100mL) except for the coliform group but

the overall water quality grade was Grade IV (pH:6.5~8.5, BOD:≦8 mg/L, COD:≦9 mg/L,

TOC:≦6 mg/L, SS:≦100 mg/L, DO:≧2 mg/L, TP:≦0.3 mg/L) due to the high

concentration of the coliform group. This was because sewage water was not intercepted and

separated by intercepting sewer pipes but directly flowed to the streams thereby increasing the

coliform group in the streams.

To solve this problem, first, improvements on water quality and sediment are needed, and

second, intercepting sewer pipes should be separated considering humans and stream

ecosystem during the ecological restoration of the streams. Thus, it is necessary for stream

restoration to aim for coexistence of human and nature by clarifying the goal of stream

restoration from the pre-plan phase.

Study on the Application of the Stream Environment Assessment Technique for Stream

Restoration Focusing on 30 Streams in Seoul Korea

Hong Kyu Ahn and Sang-Hoon Lee

Korea Institute of Civil Engineering and Building Technology, Korea

Abstract—The ecological restoration project of streams has been performed by the Ministry

of Environment and the Ministry of Land, Infrastructure, and Transport since 2000s to restore

ecological functions of the damaged streams. However, various problems occurred in the

ecological restoration project of streams because the project was focused only on making the

shape of the streams closer to that of nature without concentrating on true restoration of the

stream ecosystem.

One of the significant causes of this failure is due to no clear assessment and diagnosis on the

current status of the streams. More specifically, since the restoration direction and goals for

streams were not set up clearly from the planning phase, the stream restoration was conducted

focusingon humans rather than ecology-oriented restoration.

Furthermore, although more than 440 million dollar as been invested annually for the

ecological restoration project of streams, no systematic assessment system has been

constructed and utilized as to whether the stream environment was truly improved more than

that prior to the project or if improved, how much the environment was improved.

Thus, an opinion has been raised that a quantitative assessment on the streams was needed to

restore and maintain the ecological streams systematically.

This study evaluated the stream environment quantitatively utilizing the stream environment

assessment system with regard to 30 streams where the ecological restoration project of

streams have already been conducted or will be conducted. The stream environment

assessment has been performed comprehensively in the following five areas: physical

characteristics, water quality characteristics, stream naturalness, aquatic ecosystem health, and

citizen satisfaction.

The study results showed that the stream that had the highest grade in the stream evaluation

was selected as the reference river of the ecological restoration project of streams in Seoul

Metropolitan Government whereas the stream that had the lowest grade was selected as the

priority target river of the project.

The Impact of PDDA in CNT Counter Electrode on the Conversion Efficiency of DSSC



Abstract—Dye-Sensitized Solar Cell (DSSC) is one of the equipment to convert sunlight into

electricity. DSSC consists of anode electrode, titanium oxide ( ) thin film, sensitizer dye,

electrolyte and cathode electrode (CE). In general, platinum (Pt) is usually used for CE. This

paper studied the fabrication of CE using carbon nanotube (CNT) and CNT mixed with Poly

(diallyl dimethylammonium chloride) (PDDA) (CNT/PDDA) as the substitution for Pt

electrode. For the fabrication process, Electrophoresis Deposition (EPD) method was

employed. CNT electrode was dried at room temperature at 25 oC or annealed at 400 oC for 1

hour, and CNT/PDDA CE was dried at room temperature at 25 oC. The thickness of CE we

fabricated was around 15 . We adapted MK2 dye which was an organic dye for DSSC.

Experimental results showed that the conversion efficiency of the DSSC in the case of

CNT/PDDA CE (4.12%) was higher than that of the case of dried CNT electrode (2.78%)

and annealed CNT electrode (3.49%) under the 1 sun illumination (100 ). From this

experiment results, PDDA has improved CE ability. In addition, CNT/PDDA CE do not need

annealing process, so enabling flexible DSSC.

Shallow HVs and Geothermal Energy for Heating Purposes in Aquaculture

Hans-Uwe Dahms


Abstract—The objective of this study is to examine whether heating of aquaculture tank or

net-cages with geothermal heat from shallow hydrothermal vents (HVs) or geothermal heat

pumping (GHP) systems is feasible. Whereas shallow HVs are globally rather sparsely

distributed, geothermal energy is available worldwide, coastal or inland. The success and

economic benefits of aquaculture operations with low-temperature caused the question

whether or not lower temperature resources could be exploited with the aid of geothermal heat

pumps (GHPs). This study seeks to answer that question, and, therefore, the objective is to

determine the feasibility of heating fish tanks with GHP systems. Aquaculture involves the

raising of freshwater or marine organisms in a controlled environment to enhance production

rates. It has been demonstrated that more fish can be produced in a shorter period of time if

geothermal energy is used for aquaculture pond and raceway heating rather than water

depending on the sun for physical heating. When the water temperature falls below optimal

values, the fish lose their ability to feed because their basic body metabolism is affected. A

good supply of geothermal water, by virtue of its constant temperature, can, therefore,

optimize even a naturally mild climate. Optimum temperature is generally more important for

aquatic species than land animals, which suggests that the potential of geothermal energy in

aquaculture may be greater than in animal rearing, such as chicken and pig and chicken

husbandry. The use of low-temperature geothermal resources for space heating is quite

straightforward. If the geothermal fluid is corrosive or even slightly toxic, a plate heat

exchanger can isolate the fluid from the greenhouse heating equipment. Other alternatives

(biofuel, photovoltaic, wind) or fossil fuel peaking can be combined with the geothermal heat

in case of depleted geothermal resources (cold periods, seasonally, or at night). Strategic

importance of energy sources that are locally available for food production, and using a

geothermal resource in combination with alternative heating fossil or renewable systems for

peak heating.

Biomimetic Tactile Information Processing for Surface Roughness Discrimination

Qin Longhui and Zhang Yilei

The School of Mechanical and Aerospace Engineering, Nanyang Technological University,

Singapore

Abstract—Different from texture classification, surface roughness discrimination is more

challenging in the development of tactile sensing because of limited discriminative

information. In recent years, it is receiving more and more attentions from researchers in

various fields, most of which are based on supervised learning. But frequently all we have is

unlabeled dataset with very limited prior information, i.e., labels are not available to train the

discrimination models. Lacking the ‗teaching‘ process, it becomes rather difficult to locate the

boundary of different classes. In this paper, the ability of unsupervised surface roughness

discrimination is explored based on our developed bio-inspired artificial fingertip. At first, the

original signals are analyzed and discriminated with the most widely used unsupervised

algorithm (K-means clustering). Then the technique of discrete wavelet transform and

algorithm of sequential forward selection are utilized to identify the most discriminative

features. The unsupervised discrimination results (K-means clustering) are presented and

compared based on different distances including Squared Euclidean, Cityblock, and Cosine.

The highest test accuracy reaches 72.93%±12.55% when the distance of Squeared Euclidean

is adopted with six discriminative features. Finally, another popular unsupervised algorithm,

self-organizing maps neural network that is different from clustering, is also applied in

discriminating surface roughness with lower accuracy. The results show that unsupervised

learning algorithms with our developed tactile fingertip are capable to discriminate surface

roughness, which have great potentials in robotics and autonomous applications.

Effects of Low Soil Temperature on Antioxidant Enzyme System of Rice under Drip

Irrigation

Jun Zhang, Peng Dong and Changzhou Wei

Agriculture College, Shihezi University, China

Abstract—Rice cultivate by drip irrigation is a newly proposed water-saving rice cultivation

method. Drip irrigation (DI) rice grower found low temperature well water cause rice yield

decrease sharply, but flooding irrigation (FI) was affect not so severe. This study mainly

discusses the main reason that rice in DI was more sensitive to soil temperature than FI. The

study consisted of a two factor design with three soil temperature (18°C, 24°C and 30°C) and

two irrigation methods (flooded and drip irrigation). The results showed that the

photosynthesis intensity of rice in DI was decreased at 30℃ soil temperature，the activity of

SOD and CAT in DI was increased by 5% and 23%, Pro content increased by 27%. All data

showed rice in FI was suffer certain stress. Low soil temperature (18℃, 24℃) increased the

stress of rice in DI. Compared with FI, secondary branches and spikelet differentiation

number of rice in DI decreased significantly, protective enzymes increased more in DI than in

FI, Therefore, low temperature and drought stress may be the main reason for the serious

decline of rice in DI at low temperature.
