This study aims to examine how the usage of K-POP and Korean TV dramas influence Chinese attitude toward Korea and Hallyu as K-POP has gained its popularity all over the world. The result indicated that 'gender', 'duration of watching Korean TV drama, 'the evaluation of Korean TV dramas', 'duration of listening K-POP and 'evaluation of K-POP' are strong predictors influencing attitude toward Korea among Chinese people. On the other hand, in relation to Hallyu, demographic factors are not appeared as the predictors, however, duration of watching Korean TV dramas, 'the evaluation of Korea TV dramas' and 'evaluation of K-POP' have been shown to influence the attitude toward Hallyu in a positive way. As the practical implication this result suggests that content, either Drama or K-POP, has more importance to appeal global audience rather than famous star has. Furthermore, when variables such as watching Korea TV dramas and evaluation of Korea TV drama have been controlled, 'evaluation of K-POP' appeared as a strong predictor to influence attitude of Korea and Hallyu in a positive way. This result indicates that the main content of Hallyu in China has shifted from Korean Dram to K-POP as the New Hallyu has been coming.

The purpose of this study was to provide the data for discussion related to oral health promotion policies for the elderly by examining and analyzing the prosthesis conditions and necessity for the fixed and removable dentures among the Korean elderly. The data, obtained from 4,557 elderly aged at 65 or higher who were targeted for the 5th National Health Nutrition Survey, were analyzed through the complex sample frequency analysis, complex sample cross analysis, and complex sample logistic regression analysis. The results of analysis showed significant relevance of whole denture implant and the necessity thereof in older subjects, rural community, and subjects with lower education background, regarding the state of upper jaw/lower jaw prosthesis and the necessity for upper jaw/lower jaw fixed partial denture/whole denture. In addition, the necessity for prosthesis implant was found to have correlation with the income and subjective health condition, while the necessity for artificial teeth(denture) was found to have correlation with the gender, age, education, and subjective oral health condition. Therefore, it is considered necessary to map out the prevention and treatment policies designed to help maintain and promote oral health based on oral health education, along with the policies that aim to recover the neutralized oral health functions, in relation to the oral health of the elderly.

This paper is an introductory research to theorize women migrants' positionality in the era of globalization and the feminization of migration. It particularly examines three recent theoretical approaches within feminist studies and their application to the feminist migration study. Migration means a process of continuous negotiations of one's social and material positions within ever changing relations and situations through crossing various borders including national boundaries. Women migrants face multifaceted oppressions due to gendered relation and greater challenges to transform their identities. They embody politics of location through migration. The paper revolves around theories that explore a potential of feminist subjectivation of marginalized women such as female migrants through their identity negotiation and transformation. The theories in questions are Borderlands and the New Mestiza introduced by Gloria $Anzald{\acute{u}}a$, Intersectionality of oppressions, and Transpositions and the Nomadic Subjects by Rosi Braidotti who borrowed the theories of Deleuze and Guattari through feminist critiques. These theories all represent power relations and subject transformations through spatial metaphors. rough spatialized understandings, the paper proposes interlocking relations among space, gender and migration, and explores conceptual tools as well as epistemological insights for Korean migration study.

Purpose: p53 and bcl-2 are important markers of apoptosis. The expression of p53 and bcl-2 in gastric adenocarcinoma was examined in relation to prognosis and survival rate. Materials and Methods: The clinicopathologic data from 238 patients who underwent gastrectomies for gastric adenocarcinoma between December 1999 and July 2007 were reviewed. Immunohistochemical staining of gastric adenocarcinoma tissues embedded in paraffin blocks was performed using an Envision kit (DAKO, Glostrup, Denmark). Statistical comparisons were made between age, gender, tumor invasion, lymph node metastasis, TNM stage, Lauren's classification, cell differentiation, and the relationship with p53 and bcl-2. Results: The expression of p53 was related to cell differentiation (P=0.028) and UICC TNM stage (P<0.001). The expression of bcl-2 was related to UICC TNM stage (P=0.005). The co-expression of p53 and bcl-2 was related to UICC TNM stage (P=0.002). The co-expression group exhibited a greater reduction in the survival rate (P=0.001). Conclusion: The expression of p53 and bcl-2 nuclear proteins has significant relationships with other conventional prognostic factors and the survival rate. bcl-2 will be characterized through analysis of a greater number of patients and comparison with survival data over a longer period of time.

Purpose: This research is performed through the analysis of the dental technology students' life-style factors of their daily lives that have a close relation with health, and the self-reported symptoms which are related to psychosomatic diseases, for the production of basic data for the change of life-styles and the development of educational programmes. Methods: This research has been performed through questionnaires from the beginning of October of 2014 till the end of November through the Dental Technology students of G-do, chosen by random sampling method after informed consent, where out of the 270 papers, 258 results were used for the analysis. Results: Firstly, the results of the research was as follows: Non-smokers accounted for 61.2%, student who did not do regular physical activities accounted for 50.4%, students who had sleeping hours of 6 to 7 hours accounted for 35.7%, students who eat snacks accounted for 63.2%, students who eat breakfast once to twice a week accounted for 30.6%, students who had an average number of drinks of once to twice a week accounted for 39.9%, and students with BMI of '$18.5^{\circ}{{\neq}}22.9$' accounted for 56.2%, being the highest. Secondly, in gender, smoking (p<.001), regular physical activity (p<.001), BMI (p<.001), eat snacks (p<.05), average number of drinks (p<.05), and of the health check-up, eat breakfast (p<.05), of the year level, eat snack (p<.01), BMI (p<.01), hours of sleep (p<.05), of major satisfaction, regular physical activity (p<.01), and BMI (p<.05), and there was a significant statistical difference, but there were no significant statistical difference in religion. Thirdly, of the bodily self-reported symptoms of the correlation analysis within the life-style variables and the self-reported symptoms, multiple subjective symptoms (I), respiratory (A), eye and skin (B), and digestive organs (C) were the highest in the correlation analysis with regular physical activity (p<.01), and of mental health, impulsiveness (H), mental instability (J), and depression (K) showed highest results in correlation analysis with regular physical activity (p<.01, p<.05), lie scale (L) and irregular and life (G) with eat breakfast (p<.01), and aggressiveness (F) with BMI (p<.01), showed highest results in correlation analysis. Fourthly of the Dental technology students' bodily self-reported symptoms, life-style factors which had a statistically significant effect appeared to be regular physical activity (p<.001) and BMI (p<.05), and of the mental self-reported symptoms, causes that did not have statistically significant effect appeared to be regular physical activity (p<.05) and eat breakfast (p<.05). Conclusion: This research concludes that in order to develop correct life-style habits for health promotion and reduce self-reported symptoms related to the Dental Technology students' diseases, education for the recognition of the necessity of self health promotion must be conducted, and a education programme scheme for the Dental technology curriculum for practicing the correct life-style habits in daily life is required.

Background : Many previous studies have shown that elevated homocysteine in the serum is a well known risk factor for cardiovascular disease and this is associated with other risk factors for cardiovascular disease, but any Korean data on this is limited. Objectives : This study aimed to calculate the prevalence of hyperhomocysteinemia and to analyze the relation between elevated homocysteine and the lifestyle factors of Korean adults. Methods : We conducted a cross-sectional survey that included 650 men and 743 women (age range, 20 to 79 years) who were residents of Gwangju City in Gyeonggi-do. These subjects participated in the health interview and examination survey from November to December 2005. The total homocysteine, total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride in the serum were measured. All the participants had their body composition measured such as height and weight, and we obtained health-related behavioral information through the self-entry questionnaire. Results : Very right-handed skewed distributions of homocysteine were shown in men and women. The prevalence of hyperhomocysteinemia was 22.6% in men and 13.7% in women in Gwangju city. On the multiple logistic regression analysis, hyperhomocysteinemia was associated with age (OR=1.02, 95% CI=1.01-1.04), male gender (OR=1.60, 95% CI=1.02-2.52), severe general physical activity (OR=0.32, 95% CI=0.15-0.69) and nutrient consumption (OR=0.49, 95% CI=0.31-0.76). Conclusions : There is a great prevalence of hyperhomocysteinemia in adults of Gwangju City, Korea and it was associated with both genetic factors and lifestyle risk factors. This study can suggest that comprehensive lifestyle modification is needed in order to diminish the prevalence of hyperhomocysteinemia and to prevent CVD.
