Biotope area rate and ecological environment planning for school campuses are closely related, and we can say that ecological environment of a school that has high biotope area rate is of high ecological value. Taking that into account, in this paper, we are going to have a look at the relationship between the elements of ecological environment plan for environment-friendly schools and the biotope area rate, and we are going to come up with a method how we can increase ecological value of ecological environment and biotope area rate in a school campus through analyzing the actual biotope area rate of certified environmental-friendly schools.

본 연구는 2008년 국가경쟁력강화위원회의 발표를 필두로 현 정부가 추진하고 있는 수도권정책의 변화의 방향과 그 영향을 고찰하기 위하여 수도권정책의 변화에 민감하게 반응하는 기업의 공간수요 변화를 분석하였다. 연구내용은 수도권 정책이 기업의 입지에 미치는 영향을 살펴보고 현 정부의 수도권 규제완화 정책에 따른 기업들의 입지행태 변화 및 공간수요의 변화방향을 분석한다. 연구방법은 실증분석과 설문분석을 활용하였다. 실증분석은 1980년대 이후 통계자료를 활용하여 제조업체의 공간수요 변화추이를 분석하였다. 설문분석은 외생적 충격인 수도권 정책 변화가 기업체의 의사결정에 미치는 영향을 고찰하여 향후 기업들의 제조업용지 수요방향을 도출하였다. 연구결과 기업체들은 그동안 수도권정책으로 인하여 기업입지 결정이나 공장규모결정에 영향을 많이 받았으며 가장 큰 규제정책은 수도권정비계획법상의 권역규제와 공장총량제인 것으로 조사된다. 현 정부의 수도권규제완화로 인하여 제조업용지 수요증가가 예상된다. 특히 수도권과 충청권을 중심으로 제조업용지 수요가 증가될 것이며 강원도는 수요감소가 전망된다. 이는 수도권지역이 우리나라 중에서 가장 교통 물류 조건과 시장조건이 양호한 지역이므로 이 지역에 대한 기업선호도가 높은 까닭이다. 그러나 독자적인 경제권을 형성하고 있는 동남권이나 대경권의 경우 수도권 정책변화로 인한 영향력이 적다. 수도권지역 경우도 전체 지역에서 수요가 증가하는 것이 아니라 성장관리권역에서의 수요증가가 예상된다.

The goal of this study is to assess the spatial distribution of natural slopes and cutting slopes under would-be development. For this goal, a quantitative slope stability analysis method using GIS integrated with a computer program was developed. Through field investigations, the discontinuity parameters were collected such as orientation of discontinuity, persistence, spacing, JRC, JCS, and water depth. The distributions were interpolated from the ordinary kriging method in ARC/INFO GIS after variogram analysis. The layers showing all parameters needed for limit equilibrium analysis were constructed. The final layer using GIS works composed of 162,352 polygons, that is, unit slopes. The rock slope stability analysis program was coded by C++ language. This program can calculate geometrical vectors related to rock block failures using input orientation data and direction and dimension of strength to occur failure. Also, this can calculate shear strength of joints through empirical equations and quantitative factors of safety. This methodology was applied to the study area which is located in Jaecheon city and Danyang-gun of the northeastern Keumsu is about 135$km^2$. As a result, the study area was entirely stable but unstable, that is, factor of safety less than 1.0dominantly at the slopes near Keumsil, Daejangri, Keumsungmyun and Sojugol, Mt. Dongsan, Juksongmyun by the natural slope stability analysis. Assuming the cutting slope showing the same direction immediate, and quantitative analysis of factors of safety for a regional area could be conducted through GIS integrated with a computer program of limit equilibrium.

In this study, triggering mechanism of ground sinking was analyzed through groundwater flow analysis on the basis of a case of the ground sinking occurred in Yongsan in 2015. The results of geotechnical investigation performed before and after the ground sinking were analyzed for the accurate understanding of geological features in the study area. The numerical groundwater flow analysis was performed to evaluate the influence of the flow behavior from the surrounding area toward the excavated site using software of Visual MODFLOW. As a result, it was found from the geotechnical analysis that the strata of sedimentary layer along the sunken area in the vertical direction was mixed significantly after the ground sinking compared with the status of the soil condition before the ground sinking. Piping was occurred at the toe of cut-off wall in the sandy gravel layer, and this phenomenon was predicted by the numerical flow analysis. Sequential ground displacement scenario of the ground sinking was derived from the geotechnical in situ test and numerical flow analysis performed in this study.

The present study examined the relation between land cover condition and temperature in various types of urban green spaces. The diagram of temperature distribution showed that high-temperature zones are formed around paved areas, and low temperature zone around planted areas and grassy areas. Even in planted areas where low-temperature zones were formed, temperature was different according to hierarchical structure. That is, temperature was relatively low in areas covered with arbor + sub-arbor. With regard to land cover ratio, the increase of planted areas and grassy areas had an effect on the fall of temperature and the effect was higher in order of planted areas and grassy areas. On the contrary, paved areas and bare areas had an effect on the rise of temperature. According to the results of factor analysis, in case of the highest temperature, planted area and grassy area were put together into a factor lowering temperature, paved area and temperature into a factor raising temperature, and bare area alone into a factor of low significance. In case of the lowest temperature, grassy area and bare area were put together into a factor, and the validity of the factor analysis was proved by the analysis of urban heat islands. An increase in the number of trees by height was effective in lowering temperature, and the effect was high in order to arbor and sub-arbor, and the source of coldness in planted area was tall trees.

본 연구에서는 거시적 넓은 지역에 대한 교통 분석과 부분상세지구(sub-area)의 교통 분석을 서로 단계적으로 연계하며 상호 교통 환경 변화에 대한 영향을 동시적으로 함께 반영하여 방법을 제안했다. 이와 같은 거시적-미시적 연계 분석을 위해 거시적 네트워크 분석, sub-area analysis, 가구통행실태의 출발시각 자료, 부분상세지구의 경계지점에서 시간대별 관측 링크 교통량 자료를 융합 분석함으로써 부분지구에 대한 동적 O/D 교통량을 추정하는 실무적 방법을 제안하였다. 이렇게 추정된 동적 O/D 교통량을 입력 자료로 하여 부분상세지구에 대해 미시 교통류 시뮬레이션 분석을 실행함으로써 다양한 국소적 지구의 교통정책 분석을 가능하게 하였다. 이와 같은 미시적 동적 분석은 거시적 네트워크 분석으로는 파악할 수가 없었던 대기행렬, 교차로 지체, 차량 간 상충 등의 분석을 가능하게 한다. 따라서 교통정책의 효과를 미세한 교통현상 변화까지 분석이 가능하도록 하였다. 또한 본 연구에서는 실제 사례연구를 통해 거시적-미시적 연계 분석에 의한 부분상세지구 미시교통류 시뮬레이션 결과의 현실 설명력에 대한 검증 분석도 수행하여 미시적 동적 분석의 정책 활용 가능성에 대한 참고적 자료를 제공하였다.

The purpose of this study is to analysis the change of rural house type in Gyeongbuk province. There are 13 Gun(a kind of administrative district) areas in Gyeongbuk province. According to definition of rural area, the scopes of the research of rural houses limited the 12 places rural area(Gun area, excluded Ulleung-Gun) of Gyeongbuk province. The method of study is to compare and analyze about housing situation, structure of house, housing type and housing area etc. through the statistical data of each Gun area and other various data etc. during these 5 years. As a results of the analysis : 1) The supply ratio of housing is steadily decreasing in rural areas. 2) The houses of rural areas are changing from a detached house to multi-household house and small apartment by development near the rural area. 3) The number and area of commercial buildings are gradually increasing because of urbanization of rural areas. 4) The most houses inside area scopes in the rural area was from $60m^2$ to $85m^2$ area. And the family types of rural house are changing from large family to nuclear family and single households. 5) The structure of rural houses is changing from the brick house type to lightweight steel construction house because of cost-cutting of construction and easy way to construct etc.
