A survey was performed to investigate the infection status of zoonotic trematode (ZT) metacercariae in fish from a local market in Yangon City, Myanmar. A total of 264 fish (12 species) were collected through 4 times from December 2013 to June 2015. All collected fish were transferred to our laboratory on ice and examined by the artificial digestion method. More than 7 species of ZT metacercariae, i.e., Haplorchis taichui, H. pumilio, H. yokogawai, Centrocestus spp., Stellantchasmus falcatus, Pygidiopsis cambodiensis, and Procerovum sp. were detected. Metacercariae of H. taichui were collected in 58 (42.3%) out of 137 fish (5 species), and their average density was 42.9 per fish infected. Metacercariae of H. pumilio were detected in 96 (49.0%) out of 196 fish (9 species), and their average density was 23.6 per fish infected. H. yokogawai metacercariae were found in 40 (50.0%) out of 80 fish (5 species), and Centrocestus spp. metacercariae in 91 (50.8%) out of 179 fish (8 species), and their densities were 306 and 25.8 per fish infected, respectively. Metacercariae of S. falcatus and P. cambodiensis were detected only in mullets, Chelon macrolepis. A total of 280 Procerovum sp. metacercariae were found in 6 out of 12 climbing perch, Anabas testudineus. Morphological characteristics of adult flukes recovered from experimental animals were described. It has been first confirmed that fish from Yangon, Myanmar are commonly infected with various species of ZT metacercariae.

Currently, the alternative energy is one of the critical issues because of exhaustion of petroleum resources and its high cost. The solar cell is considered as the one of the promising alternative energy. And the solar cell can be classified to inorganic solar cell and organic solar cell. Although the efficiency of organic solar cell is very lower than the that of inorganic solar cell, organic solar cells have many advantages including low process cost, high transmittance, color variation, and flexibility. For these reasons, organic solar cells have the potential in low cost solar cell market that is challenging for inorganic solar cells. Recent researches of organic solar cell is concentrating on enhancement of efficiency, lifetime, and stability to order to commercially use. Working principles and the development issues of organic solar cells are discussed in this paper.

Excessive public loan with low interest and other tax benefits have been provided for fishermen, but much of them turned out to be little performed. There were the moral hazards of Suhyup in the process of executing the public loans. As the government gave the reimbursement on the financial loss of Suhyup resulting from the public loans, Suhyup had no responsibility of the bad debt loss. Therefore, Suhyup gave little efforts to reduce the non-performing. The government perceived this problem and tried to reduce the under-performing loans. Thus, the government decided to take limited responsibilities. Suhyup made the progress to reduce the under-performing public loans. Suhyup dealt with these situation and made the credit evaluation model of the fisherman's public loan. This paper is for the credit evaluation model in the fisherman's public loan, which explains the model development methodology and the model characteristics in detail. This evaluation model is composed of two sub-component model. the one is the quantitative model and the other is the qualitative model. The quantitative sub-model is for the identification of fishermen financial status and is based on the financial transaction information. Its development methodology is the CSS modeling for the consumer market. The qualitative sub-model is for the evaluation the business prospect and is based on the business information such as fisherman's management skills, technology, equipment. Its development methodology is the AHP. It provides the detailed information in the model development methodology, which is the ideal example such as the public loan. In addition it gives the information to the interest parties such as policy makers, suhyup and fishermen.

Once information security solution is implemented, it requires many services other than just general user management, such as malicious code analysis and security updated for consistent security against external threats or attacks, analysis of threat and attack, effectivity management of obtained security assurance, and advisory activities of security technical professionals. However, even if information security solutions provide those extra services, they are not properly treated in real market. Thus, for the security sustainable services, this study analyzes the service status of domestic information security, and suggest policy measure of price which could reflected the characteristics of information security solutions.

The purpose of this study is to understand the experiences and perspectives of the self-reliance program participants through a longitudinal qualitative study from 2006 to 2012. Based on Grounded theory approach, it examines how participants managed their lives up to now status. Through open-coding process, 181 meanings were identified. Paradigm model shows that the goal of the self-reliance program can be viewed as causal condition. However, contextual factors such as poverty experiences and child-support affected the self-reliance program participants to adapt and stay in the program rather than actively participate in the market. The finding shows that the meaning of self-reliance are differently understood by policy makers and self-reliance program participants.

The purpose of this study was to examine the consumers' purchasing behavior of budget-priced cosmetics according to the shopping orientation. Questionnaires used for this study were composed of 57 questions including 21 questions about cosmetic shopping orientation, 32 questions about budget-priced cosmetic purchasing behavior and four questions about demographic variables. Questionnaires were administrated to 20 to 49 aged 317 women who have shopping experience on budget-priced cosmetics. Data were analyzed by using factor analysis, cluster analysis, ANOVA, ${\chi}^2$-test, correlation, crosstabulation analysis, and scheffe test utilizing SPSS/WIN. The results were as follows. First, shopping orientation of cosmetics were classified into 5 factors: 'interest and impulsive purchasing tendency', 'price-oriented purchasing tendency', 'ration-oriented purchasing tendency', 'famous brand-oriented purchasing tendency' and 'brand royalty- oriented purchasing tendency'. According to the shopping orientation of cosmetics, the respondents were classified into 4 groups: 'passive shopping group', 'rational shopping group', 'active shopping group', 'neutral shopping group'. Second, when comparing each group's purchasing behavior of budget-priced cosmetics with shopping orientation of cosmetics, there was not significant difference in one time purchasing cost and the number of shop visits. In case of demographic variables concerning purchasing behavior of budget-priced cosmetics, there was significant differences in one time purchasing cost according to age, level of education and employment status. The number of shop visits had also difference according to age, level of education and monthly family income. Based on these results, marketing strategies for demographic characteristics of target market rather than the shopping orientation are needed.

Sweet persimmon, 'Fuyu', is the major cultivar for MA storage, but browning of blossom end part and fruit surface darkening occur during storage and decrease fruit qualities in fresh fruit market. Calcium (Ca) has a very important role in cell membrane and reduces Ca-related fruit disorder. Therefore, this study was conducted to investigate the effect of soluble Ca fertigation and foliar applications on soil chemical properties, root activity, and leaf nutrient status. Ca concentration in the soil was higher in both Ca fertigation (Ca-FG) and Ca+IBA fertigation (Ca+IBA) treatments than the other treatments, such as control (Cont), Ca foliar application (Ca-FA), and IBA fertigation (IBA). The increase in soil Ca improved soil pH. The Ca+IBA treatment increased root activity. Leaf Ca concentration was significantly increased by the CA-F A application, followed by Ca+IBA, and Ca-FG treatments.

The purpose of this paper is to survey the current status of service utilization in oriental medicine, to identify the determinants of consumers' decision in the service utilization, and then suggest policy implications for promoting the consumers' utilization. A multiple regression model was adopted to analyze the factors that influence consumer's decision in purchasing the oriental medical services. Data used in this research relied on National Survey Data conducted by Korea Institute of Health and Social Affairs, and sampling survey. The results could be summarized as follows.: 1. the number of visits to oriental medical institutions has shown an overall increase during the last decade since the inception of health insurance for oriental medical services. It still, however, revealed a relatively iow figure to western medical services. 2. the main factors, after controlling demographic variables, that determine consumers' selection between oriental medical services and western medical services are considered to be price, belief in effectiveness of services, waiting time for service. Implications for policy recommendation include 1. to reduce a barrier to service utilization by discounting dramatically the price of herb medicine, which is believed to be crucial in expanding market share, 2. to encourage consumer's belief in clinical effectiveness through a specialization in competitive services compared with wertern medicine, 3. to keep the affirmative image among consumers alive through an active participation of oriental medical doctors in community activities, 4 to change the health care system in favor of oriental medicine in the long run.

The current market size of insect industry in Korea is estimated at 300 million dollars and more than 500 local farms are related to many insect industry. One of the strong candidates for insect industry is Korean horn beetle, Allomyrina dichotoma. Early this year, we reported a viral disease extremely fatal to A. dichotoma larvae. While we were proceeding a nationwide investigation of this disease, it was informed that similar disease symptom has been occurred occasionally during past over 10 years. The symptom can be easily confused with early stage of bacterial infection or physiological damage such as low temperature and high humidity. A peroral infection with the purified virus to healthy larvae produced a result that only 21% of larvae survived and became pupae. Although some of the survived adult beetle was deformational, many of them had no abnormal appearance and even succeeded in mating. Later, these beetles were examined if they were carrying the virus, and all except one were confirmed as live virus carrier. This implies that these beetles may fly out and spread the disease to the nature. We found the evidence for this possibility by collecting a few wild A. dichotoma larvae which were virus infected, near two local farms rearing A. dichotoma larvae. So far, transovarial transmission of this virus to the eggs, or horizontal transmission to other commercially reared insects is not known yet.
