The purpose of this study is to investigate the effect of city dwellers' migration to the rural areas on the increase of their life satisfaction and its influencing variables. Using a quota sampling, 500 city dwellers across the country and 180 migrators to the Goesan Gun in the Chungcheongbuk-do were selected. The results showed that (a) most city dwellers want to move to the rural areas for their relaxation and rest for their retirement, but migrants' main goal is to realize their internally oriented values, (b) life satisfaction is more evident for migrants compared to city dwellers, and it is influenced by self-assessed income, self-perceived health and internally oriented value, and (c) migrators contribute to their own successful aging by using strategies of selection, optimization and compensation compared to city dwellers. The contribution of this paper is to identify and confirm that (a) migration to the rural areas is an effective way to increase individual's life satisfaction although goals of dwellers and migrators are different, (b) the specific influencing variable and their weights in increase of life satisfaction are unique in Korea, and (c) income level is a not sufficient condition but necessary condition. Several managerial implications and policy directions were suggested to help both migrators and potential migrators to settle successfully in the rural areas.

In this paper, the wage equations of local labor markets for college graduates in Korea are estimated by Dahl(2002)'s methodology to correct for selection bias. The results suggest that the variations of coefficients in wage equations across the local labor markets are mostly remained after correcting for selection bias. The gender wage gap is hardly affected by selection bias. The variations of return to education and the major premium are reduced about 18% and 11% respectively. Meanwhile, the selection bias is negligible in the national capital region, which suggests that college graduates prefer the national capital region regardless of their gender, level of education, and major.

Since the insertion of self expandable metalic stent[SEMS has became popular method for hollow organ stenosis, many attempts for further apply the stent to airway stenosis as an simple procedure has been made, but intrabronchial migration of stent or occurrence of inflammatory granuloma around stent develop occasionally and sometimes it worsen bronchial stenosis further more. This report describes 2 case of surgically treated bronchial restenosis in whom intrabronchial stent were applied for release of bronchial stenosis. Our surgical option was pneumonectomy and bronchoplasty with sleeve right middle and upper lobectomy respectively. During the operation we found the SEMSs were tightly impacted in restenotic bronchial lumen with overgrowth of granulation tissues. The bronchial obstructions occupied more than 90% of lumens in both cases, and needed much complicated procedure to be relieved. Therefore, even though the insertion of SEMS remains as a prcedure determined by the physician`s preference, it has to be considered prudently that the use of SEMS can cause severe restenosis and the surgeon has more difficulties in performing segmental resection of restenotic bronchus in patient with SEMS previously inserted. Throughout these experiences we can conclude that the insertion of SEMS must be performed only in very selected cases of bronchial stenosis.

History education is of growing significance in relation with minority group's identity issue in an irreversible trend of globalization. Archives and the cultural institution can be a major player in the reforming the history education as conducted in Britain. This paper deals with the Moving Here project led by The National Archives. The vision of the project is to overcome barriers to the direct involvement of minority ethnic groups in recording their own history of migration and to ensure this history is passed on to the next generation through schools. More than 200,000 digitised images and documents in the Moving Here have been selected from the 28 content partners' collections. In addition, TNA and the regional partners worked with minority ethnic groups to record their culture and stories. In doing so, real and lasting relation between the community and the ethnic groups has developed. The outputs of the project such as films and stories were distributed free for regional schools. The School section of the Moving Here provides a range of education resources. One of the most impressive outcome of the project is the minority's desire to have their own archives for identity and self-esteem.

PDRN (Polydeoxyribonucleotide) is a DNA-derived polymer that promotes self-renewal of damaged cells and tissues as a tissue regeneration active material. PDRN is a DNA fragment cut into small sizes by various physical or chemical methods. When administered to the body, PDRN binds and stimulates the adenosine A2A receptor on the surface of tissue cells to promote cell regeneration, accelerate wound healing, and reduce pain. Although PDRN is prepared from testis or semen of fish in most cass, PDRN extraction from various plants species was performed in the present study. Among 7 tested plant species, the highest DNA yield and purity was obtained form mugwort (Chrysanthemum coronarium, C.c), followed by broccoli (Brassica oleracea, B.o). Then, we evaluated the in vitro wound healing capacity of PDRNs prepared from these two selected plants. PDRN from C.c and B.o. significantly stimulated the wound healing process at ㎍/ml range. The present study suggests that PDRN from plant species can be an effective alternative to PDRN from marine organism.

Even though the number of Korean Americans has dramatically increased over the last 20 years, there have been very few studies that have examined the health of this population. This paper investigates the contemporary health status of Korean Americans in comparison to Koreans, employing mortality related health measures: life expectance, age-specific death rates, and leading cause of death. Overall, we find that Korean American adults enjoy longer life expectancy and lower age-specific death rates than do their Korean counterparts, suggesting superior health status of the former as compared to the latter. Comparison of leading causes of death indicates that Korean American adults (age of 25-64) are more likely to die from neoplasms than are their Korean counterparts, while Koreans show a dramatically higher probability of death from liver-related diseases than Korean Americans. When these two cause of death are regressed on various demographic and socioeconomic factors, the difference in prevalence of neoplasms between the two populations disappeared, while that of liver-related diseases remains unaffected. Based on the outcomes from this research, we suggest that Korean Americans are a self-selected group in terms of health and socioeconomic status, and they adopt healthy behaviors after immigration. This has resulted in the relatively superior health of Korean Americans as compared to Koreans.

Securing a stable residential location is one of the most important decisions that must be made in the modern society. On this matter, both individuals and their families must decide on where to live after taking into consideration various analyses. Contributing attributes in the selection of our dwelling place are crucial. In this research, influencing variables were derived from the intention to move by focusing on the characteristics of the household and traffic conditions, while implications were suggested through a comparison of urban characteristics. Suwon was selected as the case study. The result of the analysis showed the city of Suwon has longer communal satisfaction, relies on self-sufficiency, and is conscious of parking regulation. Preferences for rental housing, having infants and elementary school kids, high savings, and commuter convenience in Suwon and Gyeonggi-do ranked higher in the hierarchy of the intention to move. Compared to Gyeonggi-do, Suwon was influenced by commuters in the city and parking regulation-related variables. Meanwhile, Gyeonggi-do was affected by the lack of public transportation facilities and traffic congestion. Suwon, on the other hand, has a high share of passenger car ownership, so it seems that the psychological stability of parking space is significant. This research will contribute in the policy-making of Suwon, especially on the subject of migration prediction of citizens and real estate location selection, through analyses of variables related to the intention to move to a new residence.
