The purpose of this study was to test the effectiveness of an eight session self-management support program for improvement of patient activation, joint flexibility and health-related quality of life among medical aid beneficiaries with osteoarthritis. This study was part of a randomized and controlled research of a self-management support intervention. Participants were 60 medical aid beneficiaries who agreed to participate in this study, and were assigned to an experimental group (n=30) or control group (n=30). The 8-session and tailored program led by a trained case manager with the patient-centered approaches and cognitive-emotional-behavioral skills. Analysis included change in scores, ${\chi}^2-test$, Fisher's exact test, t-test and ANCOVA. The results showed significant increase in patient activation, joint flexibility (shoulder and right knee) except health-related quality of life in the experimental group compared to the control group. The self-management support program indicated an effect on patient activation and joint flexibility. Further research is needed to examine the outcome in the long term(9 and 12-month follow up).

This study has taken the Myeongjidong island, which has experienced spatial change due to various reasons ranging from the Japanese colonial era until today, as an instance in order to comprehend macroscopic spatial change of the Nakdonggang Delta and the adaptation process of the locals in a microscopic point of view. Spatial change of the Myeongjidong has been confirmed by collecting maps such as the atlas of late period of Chosun published in 1910, topographic map, regional geography, city records, and by applying coordinates with geographic reference function of GIS program, then checking for time sequential space change of individual regions. Space change driven by the Japanese government-general of Korea, Gimhae Irrigation Association, and by national policy or planning brought about environmental and humanistic changes unlike ever before, and land usage, housing and industry of the region and the locals experienced various adaptation processes. Such processes were compiled through collection and comparison of literature, and supplementation from interview of the locals during field study. As for the research region, it ranged from the construction of Nakdonggang bank and Myeongji seawall of 1935, agricultural rural landscape formed after the area expansion project by Gimhae Irrigation Association in 1940, to landscape that are becoming mercantile and urban due to the developmental plans of national and local governments.

Objective : To evaluate the relationship between serum leptin concentration and obesity indices in a rural population. Methods : Two hundred and nine subjects were randomly sampled from 1036 residents who had participated in the survey. Their obesity indices were measured by bioelectrical impedance analysis and anthropometry. Serum leptin concentrations were measured by immunoradiometric assay. Results : Serum leptin concentrations were positively correlated with body mass index, percent of body fat, fat mass, waist circumference, and hip circumference. Serum leptin concentrations were higher in obese or overweighted subjects than normal or thin subjects(8.5[0.9-31.4] compared with $2.7[0.1-12.0]{\mu}g/L$, p<0.01). Serum leptin concentrations were higher in women than men, even after an adjustment to body mass index$(\beta=4.183,\;p<0.01)$. According to body composition, serum leptin concentrations were more related with waist circumference in men, hip circumference in women. Conclusions : Serum leptin concentrations are positively correlated with obesity indices. Serum leptin concentrations are higher in obese subjects, in women, and more related with peripheral obesity. These findings support the hypothesis that human obesity is associated with leptin-resistance rather than leptin-deficiency.

The purpose of this study is to understand the women's experiences of negative perception, discrimination and 'ethnicized stigma' in South Korea. For this purpose, data were collected through in-depth interviews from 8 women escaped from North Korea and 4 professionals. The findings of this study are as follows: Almost of them experienced negative perception and discrimination caused by language, pronunciation intonation, and differences of ways to express their emotions. And they experienced the disapproval as the native perception and confusion of ethnic identity. Several participants in this study try to build or organize their communities to give emotional and instrumental support for them. However, in these processes, they experience emotional conflicts and crises feelings of disorganization of their communities because of they didn't have experience to involve communities, and didn't have ideas of membership and their roles. And they were learned to criticize with each other in North Korea. They worry about their families' safety in North Korea. For this reason, they can't have trustful personal relationships among Koreans including people escaped from North Korea in South Korea. They want to participate in Korean's community activities, and learn to adjust to everyday lives in South Korea. In conclusion, based upon the outcomes of this study, it is expected that any practical implications or solutions for North Korean defector's welfare would be suggested.

The North Korea have supported their own political ideological education system to maintain their basic framework of society. The north korean political education contents become from now on it be done harder. That answer is up to the government of the North Korea, and the general public in North Korea would be going after it. However, when we review this closely, both positions of the North Korean government and the general public would be different each other as before. I would figure out whether the political ideological education system in North Korea would be going on with making realistic changes or just maintaining their old system. The political and ideological education might make settled flexibility. On the other hand, we can expect that it could be reinforced by the North Korean government. For this content, this research is going to try to understand the characteristics of North Korea's ideological education policy considering both position of the North Korean government and the general public thoroughly.

Objectives : The present study takes part of the agricultural district cohort study of a certain county located in Gyeonggido and aims to investigate the difference of the heart rate variability(HRV) according to the social support level. Methods : We used data from 1727 participants of a health promotion program who are older than 40 years old. A physical examination, as well as a one-to-one interview to obtain sociodemographic characteristics, was performed with each participant. In addition, the participants completed the Medical Outcomes Study-Social Support Survey(MOS-SSS) for their the social support level to be assessed, and their HRV were measured to evaluate their autonomic function. The entire group was divided in two groups according to its MOS-SSS points to facilitate the research. Those who were evaluated as the high 25%(432 persons) were denominated as high social support (HSS) group and those who were evaluated as the low 25%(425 persons) were denominated as poor social support(PSS) group. Results : The two groups showed significant differences on the sociodemographic factor such as mean age and gender composition(p<0.05). Comparing the indices related to the HRV, the HSS group had the following values higher than the PSS group : SDNN(F=4.938, p=0.027), TP(F=8.088, p=0.005), VLF(F=6.220, p=0.013) LF (F=3.873, p=0.049). Conclusion : According to the research, the PSS group showed dysfunction on their autonomic nervous system comparing to the HSS group. The social support helps an individual overcome difficulties, helps the adaptation during the changes of circumstances and in stressful situations it serves like a buffer. Based on that, it's possible to define that a low social support level gave an impact on the autonomic function. Also, using the fact that the HRV can evaluate the autonomic function in an objective view, it was possible to visualize that it has a potential to be used as an assistant factor to evaluate the social support.

In the second part of the paper, a design strategy for an apartment complex constructed at a railway depot is proposed for vibration reduction purposes. Various design parameters such as the vehicle operating speeds, artificial land behavior, housing support structure, and apartment sub-structures are individually examined to reduce the transmission of vibrations through building structures. Building construction on an artificial land should be subjected to regulations that require the application of a vibration reduction scheme based on the mechanics that govern the vibration transmission phenomena. The implementation of these parameters at an early design stage will provide a quiet living environment for residents who may be exposed to excessive noise and vibration.

The purpose of this study is to improve and modify the evaluation method of load carrying capacity for simply supported PSC I Typed girder bridge. To do this, conventional ASD(Allowable Stress Design) and USD(Ultimate Strength Design) evaluation method were initially investigated and it was evaluated that the conventional USD evaluation method may perform the load carrying capacity as conservative because it do not consider the prestressing upper-force effect of simply supported PSC I Typed girder bridge. To reasonably evaluate the load carrying capacity, the upper-force effect should be considered to the PSC I Typed girder bridge. Thus, in this study, the MUSD method was Suggested and compared to the nonlinear FEM based-load carrying capacity using the live load factor and the efficiency of the evaluation method of load carrying capacity was investigated by experimental and analytical result. In the result of this study, the suggested MUSD evaluation method showed a reasonable evaluating result for the simply supported PSC bridge. For the new technique of load carrying capacity based on the nonlinear FEM analysis, it could effectively simulate the load-deflection relationship and the load carrying capacity of the PSC I Typed girder bridge.
