본 연구는 서울시내의 구시가지에 해당하는 도심부근 중구에 입지한 학교 학생들의 공간적 통학환경과 신시가지인 강남구에 입지한 학교 학생들의 그것을 비교 연구한 것이다. 연구를 위하여 중구의 초등학교와 중학교, 강남구의 초등학교와 중학교를 선정하여 학교주변의 유해환경을 조사하여 지도화하였고, 학생들의 통학거리, 방과 후의 사교육활동을 위한 이동거리를 설문으로 조사하여 분석하였다. 연구결과 도심부의 학교 주변에는 많은 비교육적 기능체들이 입지되어 있어서 학교주변의 정화가 필요했고, 학생들의 통학을 위한 이동거리는 긴 편이었다. 그러나 가장 중요한 것은 방과 후 사교육활동을 위한 이동거리의 차가 컸다. 강남지역 학교학생들은 도심지역 학교학생들보다 방과 후 사교육활동을 위한 이동거리가 거의 2배 이상이 되어서 빈부의 격차를 나타냈다. 이는 데일리 프리즘의 개념에서 장래의 격차를 고착화할 수 있다고 판단되었다.

The present study investigated the causes and intensity of the urban heat island phenomenon by the seasons according to the pattern of land use in Chungju City. Highest temperature and lowest moisture areas of the urban were very similar to the distribution of commercial districts, on the other hand, lowest temperature and highest moisture areas were distributed in manufacturing districts, green zones and the Hoam Lake. If appear at intensity of the distance from the outer circumference of commercial districts, wind direction and the rise of temperature, we could observe the remarkable expansion of high temperature from commercial districts toward residential districts around of downwind in all seasons. In case the effect of the wind was not significant as well, high temperature in commercial districts appeared tendency that a little spread to 1, 2 residential districts around. But checked up the intimate relations between the amount of moving heat and wind, when out of consideration that size of area was not much compared than residential areas of downwind affected by the wind. These phenomenon was relatively obvious in summer, the other side, in spring and autumn appeared a similar tendency.

This study aims at providing basic policy materials to build a basis for supplying and creating urban parks balanced across Gyeonggi province and improving the quality of life of residents through, an extensive analysis of all city parks in cities/counties in Gyeonggi province. The study result showed that first, the number of parks is only 40% of the adequate number and, thus, accessibility of Gyeonggi province residents to parks in neighborhoods is significantly low. Second, a proportion of park types in children's park, neighborhood park, urban nature park is 67% : 24% : 2%, which is adequate in Gyeonggi province as a whole. Third, as for the area of parks per resident, the area of designated park is 17.7m2/person, which is over three times of legal requirement in urban planning area (6m2/person). However, created park area is only 5.6m2/person, which fails to meet the legal requirement. Fourth, when park area of each city was compared, the areas varied significantly across cities. The Gyeonggi provincial government needs to secure funds aggressively and accelerate setting up and expanding facilities at designated parks located within the current urban areas. The findings from this study should be used as important materials when developing supply & demand policies for urban parks in Gyeonggi province. The study implicates that independent park policies and management by each city/county as well as the establishment and management of a comprehensive park policy at a provincial level is significantly important.

본 연구에서는 2001년 3월부터 2002년 2월까지와 2006년 3월부터 2007년 2월까지 31개 자동기상관측에 의한 지표 근처 기온 자료를 이용하여 서울 지역 도시 열섬의 시ㆍ공간적 구조 분석 및 그 변화의 원인을 분석하였다. 서울의 도시 열섬 구조는 주간 보다는 야간에 더 강하게 나타나고, 특히 여름철에 가장 작게 발달하는 경향을 보였다. 기온 분포의 공간구조 변화 경향은 송파 및 광진구를 중심으로 한 남동 지역에서 크게 확장되었다. 이는 송파 및 광진구 지역 주거 지역 조성의 증가에 기인한 것으로 사료된다. 일 최대 도시 열섬 강도는 주간 보다는 야간에 높게 나타났으며 새벽 시간대에 가장 크게 발달하였다. 그러나 최대 도시 열섬 강도의 빈도는 새벽 시간대보다는 한밤중에 더 빈번하였다. 이는 교외 지역의 기온이 상대적으로 증가한 때문인 것으로 사료된다. 계절에 따른 최대 도시 열섬 강도는 겨울철을 제외하고 감소한 경향을 보였다. 강우량과 강우 일수의 분석을 통해 서울의 도시 열섬 구조는 토지 이용 변화에 따른 인공열 변화의 영향 뿐 아니라 그 해의 기후적 특성에도 많은 영향을 받을 수 있음을 알 수 있었다.

This study aims to show how the urbanization of Korea has progressed for the last three decades, what its characteristics are, and how rural land use has changed by the national and district(cities and counties) level. The land use changes accompanying to the urbanization is analyzed through 3 indicators such as urbanization rate, the rate of cultivated and forest land and the rate of urbanized area. The statistical data are 30 years from 1976 to 2005 for time series analysis by the national level, and are for the two years of 1995 and 2005 by the district level. The relationship between urbanization and land use changes in the national level is analyzed using statistical analysis(Correlation Analysis). In order to analyze the dynamic and spatial urbanization and land use changes effectively in the district level, Z-score, Paired T-test, Correlation Analysis, Analysis of Variance and Chi-squire Test are used. The results show negative correlation between urbanization rate and the rate of cultivated and forest land, and positive correlation between urbanization rate and the rate of urbanized area respectively. In the aspect of the change of urbanization rate, four categories are examined. In addition, four types are characterized on the basis of the rate of cultivated and forest land and the rate of urbanized area between 1995 from 2005.

This study aims to develop rural house maintenance technique by researching and analyzing the demand for rural house by urban retirees or urbanites who are planning to retire. The target for the survey consisted of urban retirees or urbanites who are planning to retire at the ages between 40 and 65, and were divided into group A, the attendants in rural-related education, and group B, the non-attendants in rural-related education. The contents of the survey included the plan and purpose for rural settlement, the utilization form or residential form of rural house and its expected size, necessary in-house facilities, necessary community facilities, improvement and maintenance factors of rural house, political and legal support for the application of rural house maintenance, etc. The results findings of this study are as follows; 1)For both group, the major purpose of rural settlement appeared to be 'for rural life', utilization form of rural house to be 'acquired ownership or use of empty house', residential form to be 'cohabitation', expected size to be 'under 20~30 pung', and expenditure to be 'under 50~100 million'. 2)Most wanted necessary in-house facilities included backyard, multipurpose storage room for group A, and backyard, garden for group B. Necessary community facilities included boardwalk, sewage disposal unit for group A, and boardwalk, shop for group B. 3)Improvement factor for rural house showed 'poor insulation' as first factor for both groups, and for maintenance factor, 'backyard', 'under-floor heating' for group A, and 'environmental-friendly materials', 'backyard' for group B. 4)Most wanted overall political and legal support included 'support on land and real estate supply' for group A, and 'medical and transportation service' for group B. For both group, most wanted support when purchasing a house included 'provision of information on house and realestate purchase', and for legal support, 'legal support for guaranteed house and maintenance' as first factor. The results of this study could be utilized to restructure the rural residence, which would meet the diverse demand of both rural residents and urbanites by providing an opportunity for urbanites to enjoy rural life.

This study was focused on estimating instream flow, and its optimal alternative for securing the required total amount of instream flow was also researched in order to restore ecosystems and riverine aesthetics of the Mugeo Stream, the first tributary of the Taewha River flowing through the center of Ulsan. In this study the hydraulic and hydrologic conditions and water quality were investigated at specific channel reaches and representative stations of the Mugeo Stream to determine a proper estimate of instream flow. And riverine functions, such as the minimum flow, water quality conservation, fish habitat, and recreation, were considered to restore the environmental functions of the stream. As a result, the total amount of 11,500㎥/day was set as the target instream flow for the Mugeo Stream. It was chosen as the optimal alternative for securing the total external supply of 10,000㎥/day which have to be transfered from the riverbed flow diverted through the Taewha Main river at upstream of Samho bridge. The water quality throughout the Mugeo Stream channels will be improved considerably to 3-4 mg/l of BOD standard if the target instream flow is supplied and sewage is intercepted by the sanitary sewage system.

The purpose of this research was to three-criteria landuse-pattern, developing density, NDVI which were related to the heat island and find the distribution characteristic of urban surface temperature and urban heat island effects. The results of this study were as follows. According to the analysis of surface temperatures, the first grade was the outside-city like a mountain and its temperature was less than 12.18℃. The fifth grade was the downtown industrial area and its temperature was more than 23.54℃. It means Daegu-Metropolitan-City has the serious heat-island effect. the results of landuse pattern analysis, in case of fifth and forth grade, city area was occupied over 90% with residential, commercial and industrial areas, but in case of third grade, openspace was occupied over 70%. The results of developing density analysis, the temperature had high correlation with building ratio, road ratio, vegetation ratio and etc. To plan for the decrease of heat island effect needed the extension of green space, decrease of paving, but there was a limit to get the objective method for grade classification because of lacking in the basic data, the research of criteria will be accomplished continuously.

The purpose of this study is to analyze seasonal distribution of insects, birds, fishes, and benthos for Gongji stream in Chuncheon and to explore some strategies towards creating a desirable close-to-nature stream. The number of species occurred in the study stream was 23 for butterflies and 149 for other insects, 23 for birds, 15 for fishes, and 47 for benthos. The study stream was dominated by Artogenia rapae, Polygonia caureum, Cyntia cardui for butterflies, and Passer montanus, Anas crecca, Anas platyrhynchos for birds. The dominant species were Rhynchocypris oxycephalus, Zacco platypus, Carassius auratus for fishes, and Limnodrilus sp. 2, Chironomus sp. 2, Hydropsyche KUb for benthos. Attracting insect species of higher density requires planting of host plant species and stabilization of plant coverage against disturbances. To enhance species diversity and density of birds, it is desirable to provide diverse habitats including preservation of downstream wetland and natural vegetation, creation of sand bars and islands with sand and gravel, and restriction of traffic passing and parking. Restoring fish and benthos habitats needs improvement of water quality, layout of gravels and stones on sand-dominant streambed, and use of close-to-nature revetment techniques.

본 논문은 복잡하고 거대한 도시장면의 빠른 렌더링을 위한 기여도 컬링에 대한 새로운 방법을 제안한다. 시각 절두체 컬링 기술은 복잡한 장면의 빠른 렌더링에 사용된다. LOD를 지원하기 위해 영상 영역을 분할하고 가중치 쿼드트리를 생성한다. 현재 카메라 위치에서 보이는 객체들만 현재 쿼드트리의 요소가 되고 가중치는 쿼드트리의 각 객체에 할당된다. 가중치는 투사된 객체의 영상 영역에 비례하기 때문에 카메라로부터 먼 거리에 있는 큰 구조물들은 가까운 거리에 있는 작은 구조물들보다 컬링될 확률이 적다. 렌더링 시간은 보이는 객체들의 수에 독립적으로 거의 일정하다. 제안된 방법을 현재 개발 중인 새로운 대도시 구역에 적용했다. 제안된 방법은 기존의 방법과 같은 렌더링 질을 보장하며 다각형의 수를 약 9% 감소시킴을 확인하였다. 제안된 렌더링 방법은 복잡하고 거대한 장면의 고품질 실간 렌더링을 위한 응용 시스템에 효과적으로 사용될 수 있음을 확인하였다.
