The villages in island were established overcoming natural environment through Shamanism and changed by developing various industrials like transportation. Gapa Island located in southern part of Jejudo is flat topography different from the other islands. The purpose of this study is to clarify characteristics on transformation of community space in Gapa Island. For purpose, community spaces in Gapa Island are researched such as establishment, function, change, and use of community space. Spatial components in Gapa Island are like as spaces in faith, residential area, area for production, commercial zone, community space, education facilities, public offices, port, and roads. The methods of this study are literature research and interview survey for residents in Gapa Island. The results are as followings: First, community space is in charge about social, industrial, and religious function. Second, for traditional spaces separated for male and female, demarcation of space does not exist in industrial side but the demarcation has still been exist in religious side. Finally, by development of tourism new community space has been charge in festival function as well as function of space like agora for meeting with people freely, which is relatively various in function of community space in social side. Role of the dock for ship, main transportation of island, is being increasing as square.

The commercial service of KTX from April 1st 2004 has realized that whole country has shrunk into half-day life zone and it opened the times of speed. However, some technical problems unexpected before service have been raised and, among them, the noise generation at train passing was claimed by the residents living nearby the track and it is often publicized by the broadcastings and newspapers. In case where the residential area is close to the track, the installation of noise barrier at trackside is the general measures for noise reduction on bridge section and earthwork section. In case of KTX project, such measures were actually taken without any exception; however, the noise level is still high. In this study, analysis for the reason of higher noise level in spite of which the noise barriers are being installed was carried out, the sample of insulation material effective for noise barrier was manufactured and the performance of the insulation material was evaluated to verify its effectiveness

Development of transportation and communication technology has affected our daily life and has caused to separate residential places from working places. Particularly in rural areas, the life zones are incorporated into larger towns or urban areas due to their lack of cultural, social and economic infrastructures. Thus, the analysis of the depended region and the life zone is important for the planning of regional revitalization programs and related project. The purpose of this study is to propose a regional dependency model (RDM) using the origin-destination(O-D) matrix of commuters and compare it with the Nystuen & Dacey model for regional correlation. The regional characteristics are analysed and our RDM were tested using the commuting data on Seoul metropolitan area(Seoul, Gyeong-gi, Incheon) and Chungchung area. The regional correlation model can only explain the determination of regional interaction without considering the direction of regional correlation but our model can show the direction of regional dependencies.

The study utilizes remote sensing as the main monitoring means. With different spatial high-resolution, multichannel ASTER remote sensing image as the main information in Beijing city zone; with regional border and statistical data as auxiliary factor a study between the thermal space distribution character and the underground medium is analyzed based on the GIS logical algorithm and synthetic analysis technology. Results show thermal forming mechanism and the rule of distribution is mainly related to the underground medium and the change of the city distribution. Different underground medium has different degree and intensity influence on the thermal space distribution. Furthermore, urban greenbelt and water areas can reduce the thermal effect and large-scale greenbelt creates green island effect. In addition, Road net, residential area, population density, heat resources and so on have some positive effect on the thermal distribution, which increase the local temperature and intensity on the other hand. It is important to study the thermal distribution and its related factors, which contributes to the plan, construction and development of the city.

Radiological impact analyses were carried out for a near-surface radioactive waste repository at Gyeongju in South Korea. The RESRAD-ONSITE code was applied for the estimation of maximum exposure doses by considering various exposure pathways based on a land area of 2,500 ㎡ with a 0.15 m thick contamination zone. Typical influencing input parameters such as shield depth, shield materials' density, and shield erosion rate were examined for a sensitivity analysis. Then both residential farmer and industrial worker scenarios were used for the estimation of maximum exposure doses depending on exposure duration. The radiation dose evaluation results showed that 60Co, 137Cs, and 63Ni were major contributors to the total exposure dose compared with other radionuclides. Furthermore, the total exposure dose from ingestion (plant, meat, and milk) of the contaminated plants was more significant than those assessed for inhalation, with maximum values of 5.5×10-4 mSv·yr-1 for the plant ingestion. Thus the results of this study can be applied for determining near-surface radioactive waste repository conditions and providing quantitative analysis methods using RESRAD-ONSITE code for the safety assessment of disposing radioactive materials including decommissioning wastes to protect human health and the environment.

도시자연은 물리적 환경개선 기능은 물론 사회적, 정서적 측면에서도 중요한 역할을 한다. 특히, 학교에서 생활하는 시간이 많은 우리나라의 경우 학교 옥외공간을 비롯하여 인근에 조성된 녹지공간은 자연체험의 기회가 적은 도시 아이들이 가장 쉽게 자연을 접할 수 있는 일차적인 장소이다. 본 연구에서는 우리나라 대도시의 녹지현황을 학교 주변을 중심으로 살펴보고자 한다. 서울시 185개 초등학교를 선정하고, 학교 옥외공간을 포함한 반경 300m 이내(본 연구에서 '학교존'으로 정의) 주변 녹지 현황을 RapidEye 다중분광 인공위성 영상을 사용하여 분석하였다. 학교존 평균 녹지율은 약 21%이고, 최고 74%에서 최소 0.7%까지 편차가 매우 큰 것으로 나타났다. 그리고 과반수 이상의 학교존 녹지율이 20% 미만이다. 학교존 녹지율이 높은 학교 대부분이 산기슭에 위치하고 있어 산림면적이 학교존 녹지율을 높이는데 기여한 것으로 분석되며, 산림녹지의 경우 식생활력 또한 기타 도심지에 조성된 조경수목식재지보다 상대적으로 높은 것으로 나타났다. 반면, 학교존 녹지율이 낮은 학교들 대부분은 고밀 주택지 인근에 위치하고 있으며, 녹지의 식생활력 또한 상대적으로 낮게 나타났다. 도시산림을 제외한 시가화지역에서 학교존 녹지의 많은 부분을 차지하는 것은 아파트단지내 조경녹지시설이며, 그 밖에 친환경적인 학교 옥외공간이나 가로공원 등 도시오픈스페이스가 차지하는 비중은 미미하다. 이러한 현실을 감안하여, 도시계획적인 맥락에서 학교존 녹지율이 낮은 지역을 우선 대상으로 학교숲 조성사업을 지원하거나 주변지역의 옥상녹화를 장려하고, 학교주변 아파트단지내 녹지공간을 학교옥외공간과 유기적으로 연계하여 쉽게 접근할 수 있는 도시오픈스페이스로 개방하는 등의 체계적인 대책 마련이 필요하다고 하겠다.
