In freshwater ecosystems, the types of fish parasites are diverse and routes of infection are complicated because they maintain the life cycle in a variety of host animals, The present study investigated the infestation characteristics of parasites occurring in abdominal cavity of Zacco platypus in Seom River from February to October 2007. At the same time, four streams (Gam Stream, Daepo Stream, Yangsan Stream, and Yulha Stream) were also surveyed for the reference of fish infection. Aquatic insects and shellfish predominated benthic macroinvertebrate assemblages by 90.4% and 7.7% of relative abundance, respectively. Aquatic insects were composed mostly of Ephemeroptera (46.8%) and Trichoptera (29.8%), and shellfish was Gastropods. Freshwater fish was most abundant Cyprinid and Z. platypus by 85.7% and 48.8%, respectively. Among waterfowl, Anas poecilorhyncha and Egretta garzetta were dominant in August. Fish parasites observed in the abdominal cavity of Z. platypus was classified as Ligula intestinalis, belonging to Phylum Platyhelminthes Cestoda Pseudophyllidae. L. intestinalis was observed from Z. platypus in October, as the number of one individual in the Seom River and fifteen individuals in the Yangsan Stream. Infection rate of plerocercoid ranged 1.4~15.8%. We discussed the relationship between the life cycle of the parasite and the host, and hope our results to be useful for understanding the ecology of the fish abdominal parasites in Korean river ecosystem.

Keiji Kobo is a unique self-generated design research group in Japan, which was founded in 1928 when Bauhaus movement was in its peak, and which lasted ten years until the end of the Second World War, when any activity of the group became virtually impossible due to the war. With insight to see the future, the group aimed at Modern Design advocating a new spirit in architecture, and played a significant role in prosperity of Japanese Modern Design assimilating Western design trends. Pursuing of craft works for everyday life--practical furniture works--Keiji Kobo actively executed various projects to realize modern philosophy. The range of the works of this group was very large: survey, mock-up, experiment, research, exhibition, lecture, order-based sale, advertising and writing. The works of the group were oriented to serious academicism, not compromising with commercialism. Considering the peculiar political situation such as Japanese Militarism, the spirit of functionalism that the group pursued was surprisingly academical and pure. This group was relatively small and clumsy, which lasted as short as around ten years. However, strong motivation was in their seemingly quiet movements, and the influence of the group cannot be underestimated even with today's criteria. There were a number of pioneers who contributed to today's prosperity of Japan and Keiji Kobo can be estimated to be one of the pioneers in the field of design. It was found that the contemporary intellectuals hoped that the committment and activity of the group would contribute to modernization of the life quality of ordinary people. In a sense, Keiji Kobo can be estimated to be a little Japanese equivalent for Bauhaus that could not fully bloom.

The Korean society is currently at the level of discussing the living environment and the housing welfare as factors for improving the quality of life, in addition to most individuals or households residing in a living environment and housing welfare, according to industrialization and urbanization. However, even though the overall housing welfare of Korea has improved, the number of households with disabilities belonging to the social special class is not as high as that of the non-disabled households. It is a reality that cannot be done. Therefore, this study aims to identify the present condition and demand characteristics of the housing for disabled people whose social importance is currently emphasized among the social special people who can be called the social special class, as well as present the housing welfare policy to them and explain the purpose of the improvement plan. In this study, 4,277 out of 8,004 households with disabilities surveyed by the Ministry of Land, Infrastructure, and Transport in 2015 were analyzed. The result of the analysis showed that the economic characteristics (permanent income indicating the income and the user cost indicating the expenditure) of the housing demand of a household with a handicapped individual are important. This analysis will provide more effective policy formulation and policy direction for the families of the disabled.

Chlorothalonil is continuously introduced into the marine environment and has significant toxic effects on various marine organisms, however, research on its effect on seaweed is limited. Therefore, we analyzed the impact of chlorothalonil on the early life stages of major aquaculture species in Korea, Undaria pinnatifida. U. pinnatifida female gametophytes were exposed to different concentrations of chlorothalonil (0, 0.03, 0.05, 0.10, 0.20, and 0.40 mg L^-1), and their survival rate and relative growth rate were analyzed. The no observed effect concentration (NOEC), lowest observed effect concentration (LOEC), and median lethal concentration (LC50) for female gametophyte survival were determined as 0.05, 0.10, and 0.141(0.121-0.166)mg L^-1. NOEC, LOEC, and median effective concentration (EC50) for relative growth rate were 0.10, 0.20, and 0.124 (0.119-0.131) mg L^-1. Therefore, female gametophytes of U. pinnatifida are expected to experience toxic effects at concentrations above 0.05-0.10 mg L^-1 of chlorothalonil. These research findings are anticipated to serve as crucial reference data for evaluating the effects of chlorothalonil on the health of U. pinnatifida in the early life stages.

Objectives: This study was conducted to identify the awareness and practice of reducing sugar in school meals and the status of nutrition education regarding sugar reduction. Methods: An online survey was conducted on 101 nutrition teachers (dietitians) working at elementary, middle, and high schools in Daegu. Results: School nutrition teachers in Daegu recognized the need for efforts to reduce the sugar intake in the Korean diet, and it was found that elementary nutrition teachers were more aware of the implementation of the sugar reduction policy at the national level than middle and high school nutrition teachers (P = 0.002). Among the policies to reduce sugar intake at the national level, there was a high need for the promotion of self-control and limiting the sales of food with high sugar content in schools and their vicinity. The degree of practice for reducing sugar in school meals was found to be higher in the preparation, purchase, and cooking stage compared to the serving stage (P < 0.05). There was a high need for changing the preferences of the subjects for a sweet taste as a means of reducing the sugar in school meals. Thirty-six percent of nutrition teachers conducted sugar reduction education, and sending out school newsletters was the highest type of nutrition education at 80.6%. Conclusions: To effectively promote reduced sugar intake in school meals, it is necessary to change the preference of the subjects for sweetness and to conduct continuous education that can improve the awareness of people for reducing their sugar intake. For this, it is necessary to set aside time for nutrition education and to prepare an institutional framework for providing this education.
