This study tries to quantify the regional NIMBY costs to nuclear power plants. NIMBY costs are estimated as willingness to pays for avoiding nuclear power plants near residential areas through the contingent valuation method(CVM). In the study, it was assumed that the nuclear power plants were newly constructed around the residences. The result of 600 respondents living within a radius of 30 km of nuclear power plants compared to the result of 600 respondents living in the metropolitan area, which revealed that there were significant NIMBY costs to the construction of nuclear power plants in all residences. By region, the willingness to pay in the metropolitan area was greater than that in the nuclear power areas. This study focuses on NIMBY to nuclear power plants from a regional point of view, which can provide important information in establishing prudent and sound nuclear power policies.

The Global Expansion Roadmap published by the International Space Exploration Coordination Group, which is organized by space agencies around the world, presents future lunar exploration guidance and stresses a lunar habitat program to utilize lunar resources. The Moon attracts attention as an outpost for deep space exploration. Simulating lunar surface environments is required to evaluate the performances of various equipment for future lunar surface missions. In this paper, an experimental study was conducted to simulate high vacuum pressure and cryogenic temperature of the permanent shadow regions in the lunar south pole, which is a promising candidate for landing and outpost construction. The establishment of an efficient dirty thermal vacuum chamber (DTVC) operation process has never been presented. One-dimensional ground cooling tests were conducted with various vacuum pressures with the Korean Lunar Simulant type-1 (KLS-1) in DTVC. The most advantageous vacuum pressure was found to be 30-80 mbar, considering the cooling efficiency and equipment stability. However, peripheral cooling is also required to simulate a cryogenic for not sublimating ice in a high vacuum pressure. In this study, an efficient peripheral cooling operation process was proposed by applying the frost ratio concept.

As foreign immigrants are rapidly increasing, how they without previous knowledge and experience adjust themselves to local circumstances where they come to live becomes a major social issue. In order to analyze their adjustment process, this paper suggests a model which consists of relationships with local environment and people on the one hand, and of geographical knowledge and imagination on the other. The analysis of questionnaire survey based on the conceptual model suggests some findings. As there are considerable differences in the extent of their local adjustment and felt difficulties among immigration types, nationalities, and dwelling regions, foreign immigrants‘ policies should be devised proper for their type and characters.

We are using COS to purpose blocking the excess current and to protect the transformer. But the fuse of COS is melt due to the overload if the excess current flows and it destroy an air severing relations to clear as strong arc happens. Such phenomenon induces an impact ambient noise and it gives the circumstance area resident or pedestrian the fear. Thus, We are the actual circumstances which an ambient noise countermeasure establishment have desired urgently. In this study, we grasp the characteristic of an impact ambient noise which a COS fuse happens the melting and study the method to reduce an impact ambient noise.

The remains of the Bronze Age in Chuncheon region are mostly distributed on the floodplain. The floodplain in this region is made up mainly of natural levee that is high in height and is not flooded with water. The natural levee has very advantageous conditions in agriculture compared with other places. There is a high possibility that people in Chuncheon region during the Bronze Age inhabited on the floodplain and engaged in agriculture. Considering the geomorphic features and soil of natural levee, it is believed that the agriculture centered on dry-field farming was done in this region at that time.

The appreciation of cultural properties related with what the aspects of society was is mandatory to understand our culture correctly. To make over all cultural properties to our descendants without breakage or damage is our natural duty and national obligation. On the contrary, inhabitants in the preserved area should be restricted and controlled by the cultural property law. The conflict between the inhabitants in the preserved area and the government raises economical problems and damages all the time. Especially it is time to discuss to mediate between them and solve the problems. This feasible study is a proposal to settle them up through renovating abolished school in the preserve area to the museum and a case to preserve the cultual properties as well as habitant's assets in that area.

Recently, Korea is facing a trend of a fast-paced change towards a multi-cultural society, accompanied by the consequential increase in population and many changes in the peripheral environment. Particularly, the influx of multi-cultural families in Ansan City is increasing every year, but their housing environment remains in poor conditions. Actually, the research on housing policy for multi-cultural families and their housing satisfaction is restrictive. It is therefore necessary to research on how to overcome this problem, and what realistic policy alternatives are required. The purpose of this study is to present some policy alternatives to improve the housing satisfaction of the Korean-Chinese residing in Ansan City. To this end, this study conducted empirical analysis with a focus on Korea-Chinese multi-cultural families living in Ansan City through a questionnaire. As the analysis method, this study conducted frequency analysis, descriptive statistical analysis, cross analysis, and regression analysis, and used the statistical package-SPSS 20.0 as an analysis tool. As a result of the research, first, it was found that their awareness of the government housing policy is insufficient; second, they had a lot more hardships in housing due to the problem of the rising house prices caused by urban development & regeneration; third, in terms of housing tenure type, there was a higher proportion of a lease on a deposit basis and monthly rent than owner-occupied housing. Hence, this study drew the conclusion that the Korean-Chinese multi-cultural family's housing environment needs to be improved and policy support is required for Korean-Chinese. In addition, this study gives great significance in providing these research results as basic materials which make it possible to inquire into mutually reciprocal practice plan and strategic alternatives for a multi-cultural families from now on.

최근 집중호우 및 돌발홍수로 인한 물관련 피해가 늘어감에 따라 도시화된 유역의 물관리 연구에 많은 초점이 모아지고 있다. 도시 유역의 물순환에 대한 하나의 해결방법으로 각광받고 있는 LID(Low Impact Development)에 관한 많은 연구가 이루어지고 있다. 본 연구에서는 법정행정구역도를 따라 온천천 유역을 각 동별로 나누어 LID를 설치하였을 때 적용 효과가 가시적으로 나타나는 소유역을 확인하기 위하여 SWMM 모형을 통해 시뮬레이션을 실시하였다. LID 요소기술로는 토지피복에 따라 주택지에는 옥상녹화, 도로에는 투수성포장을 설치하여 각 동별로 LID 적용 전 후에 대한 유출량, 침투량, 첨두유량, 유출계수 등을 비교 및 분석하는 연구를 수행하였다. 온천천 유역 14개 동에 대한 분석을 실시한 결과, 유출량 감소율의 경우 수민동(85.24%), 거제동(83.23%), 명장동(82.81%), 침투량 증가율은 수민동(162.8%), 안락동(105.1%), 복산동(71.03%) 순으로 하천 주변의 거주지가 밀집된 지역에 가시적인 효과가 나타났으며, 첨두유량 감소율은 청룡동(81.82%), 장전동(80.37%) 부곡동(79.39%) 순으로 소유역의 경사가 급한 지형에 효과가 좋은 것으로 나타났다. 유출계수 감소율은 유출량 감소율의 경우와 마찬가지로 나타났다. 도시 유역에 보다 나은 물순환을 위하여 LID 요소기술을 설치할 때 저감시키거나 증가시키려는 매개변수를 확실히 선정하는 것이 LID 효과를 극대화 할 수 있다는 점을 확인하였다.
