  • The beneficial effects of hypoxic preconditioning are abolished in the diabetes. The present study was designed to investigate the protective effects and mechanisms of repeated episodes of whole body hypoxic preconditioning (WBHP) in db/db mice. The protective effects of preconditioning were explored on diabetes-induced vascular dysfunction, cognitive impairment and ischemia-reperfusion (IR)-induced increase in myocardial injury. Sixteen-week old db/db (diabetic) and C57BL/6 (non-diabetic) mice were employed. There was a significant impairment in cognitive function (Morris Water Maze test), endothelial function (acetylcholine-induced relaxation in aortic rings) and a significant increase in IR-induced heart injury (Langendorff apparatus) in db/db mice. WBHP stimulus was given by exposing mice to four alternate cycles of low (8%) and normal air O2 for 10 min each. A single episode of WBHP failed to produce protection; however, two and three episodes of WBHP significantly produced beneficial effects on the heart, brain and blood vessels. There was a significant increase in the levels of brain-derived neurotrophic factor (BDNF) and nitric oxide (NO) in response to 3 episodes of WBHP. Moreover, pretreatment with the BDNF receptor, TrkB antagonist (ANA-12) and NO synthase inhibitor (L-NAME) attenuated the protective effects imparted by three episodes of WBHP. These pharmacological agents abolished WBHP-induced restoration of p-GSK-3β/GSK-3β ratio and Nrf2 levels in IR-subjected hearts. It is concluded that repeated episodes of WHBP attenuate cognitive impairment, vascular dysfunction and enhancement in IR-induced myocardial injury in diabetic mice be due to increase in NO and BDNF levels that may eventually activate GSK-3β and Nrf2 signaling pathway to confer protection.

  • The Hanja used in Korean are traditional Chinese characters, but what Chinese people use now is simplified characters. So, there are differences in pronunciation and meaning between the characters used by Korean and Chinese. More than 70% of the Korean language vocabulary derived from or were influenced by hanja. For the inheritance and development of traditional culture,and for the communication among countries of the Chinese characters cultural circle in Northeast Asia, should we build up an authentic Chinese education system. But the government hasn't pay much attention to this work, and the government's policy can't implement the efficient education. Consequently, in these days, there are more and more Korean people who are functionally illiterate in Chinese. Recently, proficiency tests of Chinese characters are expected to promote the development of Chinese education. But, most Koreans' motives for Chinese study are usually to pass the college entrance exam or to compete for jobs. However, after passing the test, the motive for studying gradually fade away. It is the basic problem faced by Korean Chinese character education. Since the 1950s, various character education methods have been studied in China, the research results were appliedin their textbooks and other materials. Therefore, a well-organized and efficient learning-by-step education system was built up. At present, China's literacy education in the textbooks utilizes a range of methods including revisional centralized and distributed. Unfortunately, there is still one shortcoming worthy of concerns: how to solve the problems due to the simplification of traditional Chinese characters? Is it possible to revive traditional Chinese characters? Before adopting the results of research on China's literacy education and applying them to our character education, we should consider our specific situation carefully. Adopting the research results with cautious review and objective criticism should have a positive impact on Korean Chinese character education.

  • Over thousands of years oriental traditional medicine has developed a theoretical and practical approach to treat and prevent diseases and to promote people's health in China and Korea. In China, the integration of traditional Chinese medicine into the national healthcare system began in the late 1950s. This was in response to national planning needs to provide comprehensive healthcare services. On contrary to China, South Korea established the parallel operation of two independent medical systems in 1952. Hence there has been a political conflict between oriental and modern medicine over issues of fee, the ability to sell and prescribe herbal medicines, and the licensing of practitioners in traditional medicines. Given this background. This study is to compare peoples' attitudes and opinions for oriental traditional medicine by ethnicity (Chinese, Korean-Chinese and Korean). Chinese and Korean-Chinese were more used and satisfied with traditional medicine treatment and traditional practitioners compared with Koreans. The proportion of Koreans who reported the cost of traditional treatments was expensive was higher than those of Chinese and Korean Chinese. Most of Chinese, Korean-Chinese, and Koreans reported that they would use traditional medicine: 1) when they would have some disease to be treated best through traditional medicine; and 2) when traditional practitioner had a reputation and lots of experiences for those diseases. Most Korean people reported that oriental and western practitioners should cooperate each other to improve the quality of care. Therefore, policy framework including integration of traditional and western medicine, regulation, etc. is needed. In addition, research is needed to determine which diseases is treated best through traditional medicine.

  • The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.

  • This paper looks into the process of the formation of a Chinese ethnic place in Jayang-dong, Gwangjin-gu. In doing so, the paper reviews Chinese immigrants with the approach of cultural adaptation. Specifically, in-depth interviews with both Chinese immigrants and Korean native people in Jayangdong has been conducted to analyze the local residents' reaction to the Chinese immigrants, the conflicts between the natives and the Chinese immigrants, and communications among them. Based on the analyses, the paper recognizes the change of relationship between the natives and the Chinese immigrants in the development of the ethnic place. The relationship between the Korean native people and Chinese immigrants in Jayang-dong turns out to be more positive than that in other Chinese towns. In Jayang-dong, in the early period of the formation of the area, the Korean native people and Chinese immigrants used to have conflicts. However, as time goes by, the conflicts has been resolved and they have embraced each other through interchanges between them based on mutual understanding and consideration. Cultural adaptation in Jayang-dong has occurred in the way that the immigrants have been integrated into the mainstream society based on the connectedness with both the native people and immigrants embracing each other.

  • LRP15 is a novel gene cloned from lymphocytic cells, and its function is still unknown. Bioinformatic data showed that LRP15 might be regulated by DNA methylation and had an important role in DNA repair. In this study, we investigate whether the expression of LRP15 is regulated by DNA methylation, and whether overexpression of LRP15 increases efficiency of DNA repair of UV-induced DNA damage in HeLa cells. The results showed (1) the promoter of LRP15 was hypermethylated in HeLa cells, resulting a silence of its expression. Gene expression was restored by a demethylating agent, 5-aza-2'-deoxycytidine, but not by a histone deacetylase inhibitor, trichostatin A; (2) overexpression of LRP15 inhibited HeLa cell proliferation, and the numbers of cells in the G2/M phase of the cell cycle in cells transfected with LRP15 increased about 10% compared with controls; (3) cyclin B1 level was much lower in cells overexpressing LRP15 than in control cells; and (4) after exposure to UV radiation, the LRP15-positive cells showed shorter comet tails compared with the LRP15-negative cells. From these results we conclude that the expression of LRP15 is controlled by methylation in its promoter in HeLa cells, and LRP15 confers resistance to UV damage and accelerates the DNA repair rate.

  • Based on Nisbett and his colleagues' theoretical model "Holistic" and "Analytic" which show the differences in cognitive style of Eastern Asian and Westerners, the author hypothesized that the differences in cognitive style of people from diverse cultural backgrounds may influence their perception and usage of webpage. An experiment was carried out and the Eye-gaze device was used to assist to explore the relationship. The results revealed the relationship between cognitive style and webpage design. different cognitive style results different viewing pattern on webpage. Chinese people are more likely to have a holistic view of the whole page first and then focus on detail, while French people tend to read the heading information first and then proceeding down the page. Chinese emphasized the background as well as the whole look and feel of the webpage more, while French noticed the independent contents and element designs more on the webpage.

  • The purpose of this paper is to analysis on periodical changes of rural houses of Korean-Chinese people residing in Yanbian area, China focused on periodical changes of floor plans according to Chinese government's policies and regulations influencing on rural houses. Changes of floor plans are classified into four periods; immigrating settled period, 1960-1970s, 1980-1990s, and after 2000. Total number of 67 cases were analyzed that data was collected 48 cases of literature studies and 19 cases of field study in Yanbian, China. The results are as followings. In immigrating settled period, floor plans of the rural houses have tended to be continued the pattern of the Korean traditional rural houses. Nevertheless China was changed socialism system, rarely floor plans were influenced by the system during this period. From 1960s to 1970s, the livestock and rural mechanization are influenced by the "People's Commune" policy. The "Barn" and "Mill" were converted into "warehouse". The residential part consists of one Jeongji (space mixed dinning and kitchen) and one to three of Ondolbang (room). From 1980s to 1990s influenced by the policies of "Cultural Revolution", "Birth Control" and "Chinese Economic Reform", the Korean traditional customs like "elders first" and "distinction between the male and female have been gradually vanished. Meanwhile, spaces of the rural houses have consisted of Jeongji, big Utppang (room), and warehouse. Each space is opened and mutual. Since 2000, influenced by the policy of a "new Socialist Countryside Construction", the bathroom and kitchen are added in interior spaces, the life style in rural houses has been changed as for both the sedentary style and western style.

  • The purpose of this paper is to explore Chinese students' difficulty and understanding of their relationship with Korean students. A total of 20 Chinese undergraduate students at a private university in Seoul were interviewed. Findings show that (1) Chinese students were separated from Korean students in their relationships; (2) Chinese students understood that Korean students were indifferent to Chinese students and pursue purposeful relationships with Chinese students; (3) Chinese students recognized that Korean students and people perceive China and Chinese people negatively, reasons including mass media in both China and Korea, political and economic relations between two countries, and lack of intercultural education in Korean education. This paper emphasizes the separation of Chinese students from Korean students despite the successful increase of international student population in Korean higher education, and concludes that international student recruitment and internationalization efforts in Korean higher education need to be directed toward facilitating relationships between Korean and international students, thereby promoting their quality of educational and sociocultural experience.
