BACKGROUD/OBJECTIVES: Allomyrina dichotoma larva (ADL), one of the many edible insects recognized as future food resources, has a range of pharmacological activities. In a previous study, an ADL extract (ADLE) reduced the hepatic insulin resistance of high-fat diet (HFD)-induced diabetic mice. On the other hand, the associated molecular mechanisms underlying pancreatic beta-cell dysfunction remain unclear. This study examined the effects of ADLE on palmitate-induced lipotoxicity in a beta cell line of a rat origin, INS-1 cells. MATERIALS/METHODS: ADLE was administered to high-fat diet treated mice. The expression of apoptosis-related molecules was measured by Western blotting, and reactive oxidative stress generation and nitric oxide production were measured by DCH-DA fluorescence and a Griess assay, respectively. RESULTS: The administration of ADLE to HFD-induced diabetic mice reduced the hyperplasia, 4-hydroxynonenal levels, and the number of apoptotic cells while improving the insulin levels compared to the HFD group. Treatment of INS-1 cells with palmitate reduced insulin secretion, which was attenuated by the ADLE treatment. Furthermore, the ADLE treatment prevented palmitate-induced cell death in INS-1 cells and isolated islets by reducing the apoptotic signaling molecules, including cleaved caspase-3 and PARP, and the Bax/Bcl2 ratio. ADLE also reduced the levels of reactive oxygen species generation, lipid accumulation, and nitrite production in palmitate-treated INS-1 cells while increasing the ATP levels. This effect corresponded to the decreased expression of inducible nitric oxide synthase (iNOS) mRNA and protein. CONCLUSIONS: ADLE helps prevent lipotoxic beta-cell death in INS-1 cells and HFD-diabetic mice, suggesting that ADLE can be used to prevent or treat beta-cell damage in glucose intolerance during the development of diabetes.

This is a basic study to establish marine activity criteria based on the seakeeping performance of less than 10-tons fishing vessels. These vessels account for approximately 95% of Korea's currently registered fishing vessels, and accidents and loss of life are also occurring during marine activities such as navigation, and fishing. Accordingly, the Ministry of Oceans and Fisheries has set a regulation of vessel traf ic control to restrict the operation of fishing vessels when the high seas watch takes effect, but it is applied equally without criteria according to the ship ton level and wave height; therefore, many differences may exist in ship fluctuations. Because the fluctuation of the ship owing to the wave height can be a factor in marine accidents by reducing the sense of boarding and performance of equipment, the seakeeping performance must be reviewed during waves to secure safe marine activities such as navigation and fishing. However, the review for the fishing vessel of established marine activity criteria based on the seakeeping performance is insufficient. Accordingly, the seakeeping performance was evaluated for a 10-ton class (G/T 9.77 tons) fishing vessel in Korea, and the level of marine activity according to the significant wave height and ship speed was interpreted by applying the operation and survival of the established seakeeping performance criteria. The analysis results indicated that the roll of the ship exceeded the operation criteria from 0.4m and the survival criteria from 2.2m. The pitch of the ship exceeded the operation criteria from 1.7m and did not exceed the survival criteria until 3.0m. However, the rolling exceeding the survival criteria from 2.2m may not be safe. Therefore, fishing vessels with less than 10-tons can leave before the high seas watch takes effect. However, they did not satisfy the criteria for evaluating the performance of the sea in relation to marine activities. Although this study was limitedly evaluated for 10-ton fishing vessels, it is expected to be of great help in preparing marine activity criteria.

I researched the acceptance attitude to the multiculturalism of Korean people and the relationship between language and society through two Korean films, and . And I researched the language form in the multicultural families in the way conducting the survey targeting international marriage immigrant women. The content and conclusion in shortly are as in the following. (1) The acceptance attitude to the multiculturalism of Korean people is somewhat positive in such a case having no interests among themselves. (2) It depends upon the society and the culture for the foreigners to come into contact and learn the language easily. It means well-adapted to the certain society for the foreign workers to use status-language such as slang and jargon in the society. And this is the good example to show us the relationship between the language and certain society. (3) The language form of the multicultural families in Korea is mainly Korean, but two languages are used in order to communicate well with monolingual. This is called 'bilingualism', and according to the result of my research I think it is 'listening comprehension type bilingualism'. From this time forward it is urgently needed to develop the contents in relation to multiculturalism and the 'bilingualism' education program for multicultural families instead of the education of Korean being limited to communication itself in order to improve adaptiveness to multiculturalism in Korean society.

The impact of urbanization on local meteorology (e.g., surface temperature, PBL height, wind speed, etc.) in the Greater Seoul Area (GSA) was quantitatively evaluated based on a numerical modeling approach during a 1-month period of 2001 (9 Sep. through 8 Oct. 2001). The analysis was carried out by two sets of simulation scenarios: (1) with the global land use and topographic data from the U.S. Geological Survey (USGS) in 1990s (i.e., LU-USGS case) and (2) with the land use data from the Environmental Geographic Information System (EGIS) along with the 3 sec elevation data from the Shuttle Radar Topography Mission (SRTM) in 2000s (i.e., LU-EGIS case). The extension of urban areas in the GSA (especially, the southern parts of Seoul) accounted for 1.8% in the LU-USGS case and 6.2% in the LU-EGIS case. For the simulations, the surface temperature and PBL height due to urbanization in the LU-EGIS case was higher (the differences of up to $0.1^{\circ}C$ and 36 m, respectively) than those in the LU-USGS case, whereas the wind speed (up to 0.3 $ms^{-1}$) in the former was lower than that in the latter at 1500 LST. The increase in surface temperature due to urbanization in the GSA (especially, the southern parts of Seoul) was led to the strong convergence of air masses, causing the early sea breeze and its rapid propagation to inland locations. In addition, the vertical mixing motion in the extended urban areas for the LU-EGIS case was predicted to be stronger than that for the LU-USGS case and vice versa for the original urban areas.

The purpose of this study is to conduct a meta-analysis of 18 papers that can be verified among the papers on the subject of TPM. Five hypotheses were set for the analysis and meta - analysis was carried out with CMA as presented in each research paper. As a result of analysis, I-square value is more than 75% in four hypotheses. Therefore, the null hypothesis that the size of the population effect is the same for all studies was rejected. The reason for the heterogeneity is that the research characteristics such as the distribution of the respondents, the study conditions, the study period, and the study area are different. In this case, a summary statistic of the individual studies that can be classified according to the characteristics of the research is needed to analyze the effect size difference. However, individual studies do not provide a summary statistic that can classify the effect differences, so it is not possible to analyze the causes of heterogeneity.

The medical tourism industry, a convergence of medical services and tourism, has been getting more and more popularity as a new value-added industry in the 21st century. Accordingly, the number of professional workers within this industry has been increasing, and the role of educational institutions to cultivate well-equipped human resources has also become critical. However, compared to practically activated medical tourism-related education programs, studies investigating the effectiveness of these education programs are relatively rare. Therefore, this study attempts to examine the effect of five dimensions of medical tourism education service quality (i.e., tangibles, reliability, responsiveness, assurance, and empathy) on learners' education satisfaction and transfer of education training. In addition, the moderating roles of national relations as well as organizational characteristics (i.e., transfer climate and support of supervisors and colleagues) in the relationship between education satisfaction and transfer of education training are further verified. The results of the structural equation model (SEM) using 151 samples from respondents with experience in completing medical tourism education programs reveal that tangibles, reliability, and assurance are found to have a significant impact on education satisfaction, which in turn leads to a high level of transfer of education training. Moreover, it is found that national relations and support of supervisors and colleagues play a moderating role. This study would provide guidelines for improving the efficiency of educational institutions, creating outcomes for learners' affiliated firms (e.g., hospitals), and promoting medical tourism at the national level from the perspective of medical tourism education.

This is a user experience study of factors that should be considered in designing home appliances experience service. Untact services are emerging, but the development of home appliances sector is in early stage. Based on the six factors of Stephen P. Anderson's Creating Pleasurable Interface Model, this study conducted surveys, 1:1 in-depth interviews, and participation observations to measure and analyze user experience. In this study, I compared 4060s and 2030s's user experience in that the untact services raise the digital alienation among middle-senior-aged. As a result, there were significant differences between the two, including the opposite satisfaction in terms of reliable, usable and pleasurable factors. I hope that this study will be of strategic help in designing future home appliance experience services.

This paper dealt with the application of a numerical method developed by the authors using the matching method proposed in the previous paper on "The Nonlinear motions of cylinders(I)[16]", and Cauchy's theorem to the problems associated with hydrodynamic forces acting on a heaving cylinders translating in a calm water and also motions of cylinders in waves. In spectral method. body boundary condition in submerged case is satisfied exactly but one in floating case is not satisfied exactly. In the numerical code developed here, the boundary condition at the free-surface and body surface is satisfied exactly at its instaneous position. It is of interest to note that the present scheme could be applied to a free-surface-piercing body without experiencing a difficulty in the numerical convergence. The computed results are compared with other results([6], [12]).
