  • The purpose of this study is to analyze characteristics of literature on the residential environments of Korean-Chinese people residing in China. The number of such studies on residential environment is a total of 123, of which 86 (69.9%) are Korean studies and 37 (30.1%) are Chinese studies. Research has been conducted in China since the 1980s, but from 1990s onward, research was conducted in Korea following the establishment of diplomatic ties between the two nations. More studies related to history, society, and tradition have been conducted in China than Korea because China is a multiracial nation and Korean-Chinese people comprise an ethnic minority. In terms of residential environment, the majority of studies are related to architecture and space and are typically focused on villages and housing. Studies on traditional housing of the Korean-Chinese focus on general characteristics of traditional housing, targeting China's three northeast provinces and the Yanbian Korean Autonomous Prefecture of China. Studies on modern housing of the Korean-Chinese have mainly been conducted in Yanji City in China. The reason for this is that 41% of Yanji City's population is Korean-Chinese, a distinct difference can be seen between Yanji City and other areas regarding changes of modern housing, and ondol (the traditional Korean floor heating system) is commonly found in modern housing there.

  • Recent changes in the dynamics of national economies, market liberalization, changes in technologies and movement of capital have had a major effect on the Asian Pacific region since the early 1990's, as there has been an increasing role for foreign housing developers in those countries that experienced economic liberalization, high urbanization rates and reforms in the housing sectors. Recently the cosmopolitan cities of Indonesia attracted a global interest due to its rapid economic development and great potential of population and natural resources. New town development emerged as one of the solutions to reduce urbanization problems in Indonesia. This study aims to explore the contemporary planning principles of new town developments in representative new town projects supplied by of major housing development companies in Indonesia. We conducted case study on the new town named Kota Baru Parahyangan, which is located in outskirt of Bandung, the third biggest city in Indonesia and supplied by PT. Belaputra Intiland. As a result of this study, we can identify unique characteristics of new town development in Indonesia.

  • Wolsong Unit 2,3&4 has been performing a containment integrity test during power operation. This test could impact to the safe operation during test. If an accident occurs during pressure dropping phase, reactor trip can be delayed because of the increased pressure difference which causes a time delay to reach the trip set-point. On the contrary, if an accident occurs during pressure increasing phase, reactor trip could be accelerated because the pressure difference to the trip set-point decrease. Point Lepreau nuclear power plant, which installed GCLMS (Gross Containment Leakage Monitoring System) in 1990, has discontinued the test since 1992 due to these adverse effects. Therefore, we evaluated the risk to obviate the GCLMS test based on PWR's ILRT (Integrated Leak Rate Test) extension methodologies. The results demonstrate that risk increase rate is not high in case of performing only ILRT test at every 5 years instead of doing GCLMS test at every 1.5 years. In addition, the result shows that GCLMS test can be removed on a risk-informed perspective since risk increasement is in acceptable area of regulatory acceptance criteria.

  • The epidemiology of plant disease deals with the dynamic processes of host-pathogen interactions, which determine the prevalence and severity of the disease. Epidemic processes for most foliar diseases of plants follow a series of steps: arrival of pathogens on plant surfaces, initial infection, incubation period, latent period, sporulation, dissemination of secondary inoculum, and infectious period. These complex biological processes are influenced by the environment-Man also often interfers with these processes by altering the host and pathogen populations and the environment. Slowing or halting any of the epidemic processes can delay the development of the epidemic, so that serious losses in yield due to disease do not occur. It is generally recognized that the most effective and efficient method of minimizing disease damage is through the use of resistant cultivars, particularly when other methods such as fungicide applications are not economically feasible-Populations of plant pathogens are not genetically uniform nor are they necessarily stable. Cultivars bred for resistance to current populations of a pathogen may not be resistant in the future due to selection pressures placed on the pathogen populations. Understanding population development and genetic variability in the pathogen, and knowledge of the genetics of resistance in the plant should help in developing breeding strategies that wi1l provide effective and stable disease control through genetic resistance. In the United States, soybeans have ranked first in value of crops sold off the farm in recent years. Soybeans have been the leading U. S.

  • Purpose: This study was to identify the relationship between sexual attitude, sexual identity, sexual permissiveness in girls in junior high school, Method: The participants were 587 female students in Chungnam Province. Data were collected by questionnaire surveys using convenience sampling. The instruments were the Sexual Attitude Scale by Kim (1997), the Sexual Identity Scale by Jung (1990), and the Sexual Permissiveness Scale developed by Reiss (1964). Data were analyzed by the SPSS 11.0 program. using descriptive statistics, Pearson correlation coefficients, t-test, ANOVA and Tukey's multiple comparison. Results: The relationship between sexual attitude and sexual permissiveness had a positive correlation (r=.440, p-0.000). Sexual identity was positively correlated (r=.180, p=.036; r=.222, p=.014) with both sexual attitude and sexual permissiveness, but maleness was the only positive correlation (r=.258, p=.014) with sexual permissiveness, no sexual specialization was the only characteristic that had a positive correlation (r=.188, p=.046) with sexual attitude. Conclusion: These results suggest assessment of these factors and treatment fitted to individual needs are important for correct sexual culture. There should be repeated research on various population groups. Moreover, it is considered necessary to carry out factor-related theoretical researches on several variables related to sex through multilateral literature reviews.

  • This study focuses on the genealogical analysis of the urban public spaces by the local history of Seoul which is significantly different from western cities. The analysis targets the discourse of the urban street which defines urban space-structure among the urban public spaces. Based on the analysis, we define the progress levels of urban public design policy in Seoul. Firstly, in 1960's and 1970's, 'urban reconstruction' was intensively carried out for the country modernization, and 'vehicle preferred street expansion' resulted in damages to historical inheritance, in-humanized street, and cultural uniformity. 1980's and 1990's would be defined as 'politic acceptance of plural values to the urban street.' There were the Olympic Games held in Seoul in 1988, which were the celebrations of the 600th capital establishment and the autonomous local government system. In the meanwhile, diverse values on the urban street were discussed in terms of globalization. There also were the self-reflection for the urban skyscrapers and high-population rate, the cultural uniformity of urban street, and the commercialization in downtown with urban reconstruction plans. Then, the sense of landscape and amenity was focused. Various urban projects and regulations were held according to the changes of value recognition. 2000's can be defined as 'introduction to the organic integration and the urban public design governance.' In the 21st century, types of recognition have changed significantly, which include publicness, humanism, sustainability, symbolism, artistry, placeness, and communication. They cause the establishment of ordinances and the installation of integrated organization via urban design administration. The legislation has been revised in order to support the various methods for the maintenance and operation of urban landscape in terms of local characteristics. New regulations were established for residents to participate in the processes of the urban planning with street design policy.
