This study analyzed the budget investment plans for the unit-project items(UPI) of 176 project districts for the rural village comprehensive development projects (RVCDP). This study classified the master plan reports of 176 project districts into 88 unit project items in aspect of project management, in order to analyze characteristics of distribution of budget in each project item. Most of all unit project items have similar types of uniform distribution with plus skewness in frequency pattern analysis except the total budget of the project district. This study analyzed the characteristics of budget distribution per province, year, and geographical types of region. Furthermore this paper also analyzed ratio of budget in unit project items to find out distribution pattern of each budget between project items over time. The hierarchical system for UPI of RVCDP consisted of three steps, which are 4 items of the first step on Strength of Rural-urban Exchange & Regional Capability (RURC), Green-income Infrastructure & Facility (GIF), Culture- health-welfare Facility, and Eco-environment & Landscape facility (ELF), 13 items for the second one, and 52 items for the third project items. From the results of the budget investment analysis for 5 years from 2004 to 2008, the budget investment ratios of RURC and ELF have steady state for every year, while GIF in decreasing and ELF in increasing over time. The ratios of UPI on infrastructure were decreased, whereas those on culture, health, and welfare were increased. Portion of tow project items among 52 items, which are community centers for village residents and rural experimental study facility, has 30% of total budget investment. Futhermore, the budget ratios of seven project items showed 50% of total budget. Average value of project budgets for five years was optimized as a type of exponential function in the case of decent array for ranking order.

This study presents a demand modelling for landfill gas, which is used as alternative energy source for district cooling business. By analyzing the cost minimizing behavior of producer facing with three alternative energy sources such as electricity, cooling heat water, and gas, a demand function for landfill gas is derived from the optimal operating time of gas fired production facility, and estimated using unpublished data, which are associated with Seoul city's development plan for Sang-am area. The estimation results repeals that Seoul City could supply the land-fill gas of 13.76 million cubic meters each year at the price of about 16 won per cubic meters. However, if the investment costs associated with installation of gas collecting facilities are treated as sunk costs, annual amount of gas supplied is expected to increase to 14.22 million cubic meters at a lower unit price of 14.76 won.

The purpose of this study is to investigate the effect of floor area ratio incentive system for Long-life housing certification system by simulation of five recently built apartment complexes. Apartments that are certified as superior in Long-life housing can receive 10% of the floor are incentive in Seoul. However, the difference between base and permitted floor area ratio are in general residential area of class 2 and 3 is not more than 20%. limit of feasible allowance incentive is limited. Even if there is an unrealized permitted floor area ratio, there is no reason to apply the Long-life housing certification system preferentially. Because the items of the floor area ratio incentive provided by the District Unit Plan are various, it shows that the floor space ratio incentive for Long-life housing certification system has little effectiveness. To enhance the feasibility of incentives for the Long-life housing certification system, improvement in the urban planning level, including district unit planning, including the design criteria for apartments in Seoul, is needed.

Electric energy is indispensible of the development of the industrial and living sector. Among the energy sectors, the building area shares 20% of the produced electric power in Korea. As we plan to supply the apartment, we need to forecast the required amount of the electric energy and supply the infrastructure to apartment for the lighting, cooling. Nonetheless, it is not easy to forecast the required amount of the electric energy, considering the management aspect, building physical aspect and social-geographic aspect. In this paper, it studied the estimation model of the electric energy, reflecting the affecting variables such as total area, number of household, geography and so on. The estimation model is proposed in 3-types which explained in central heating, individual heating and district heating, and each type have two estimation model, reflecting the affecting variable and corelation between variables to eliminate the muticolinearity. The unit of electric energy consumption per area and year is similar in three heating type and the results are as follows; the central heating is $34.446kWh/yr{\cdot}m^2$, individual type is $35.756446kWh/yr{\cdot}m^2$ and district heating is $34.285446kWh/yr{\cdot}m^2$.

도시화로 인한 산업비율 증가는 도시의 기온이 주변지역보다 높아지는 도시 열섬(Urban Heat Island)현상을 유발하였으며 기후변화와 함께 그 강도가 점점 증가하고 있다. 열섬현상이 발생하는 여러 도시 중에서도 서울시는 각 구 또는 동별로 시가화 정도, 녹지율, 에너지소비량, 인구밀도가 다 다르기 때문에 열섬현상의 강도역시 다르다. 따라서 본 연구에서는 서울특별시를 대상으로 행정구, 행정동 단위 열섬현상강도(UHI Intensity)를 추출하여 행정구역별 차이를 확인하고 세 가지 범주(기상상태, 인위적 열 발생, 토지이용특성)에 포함되는 변수들과 선형회귀분석을 실시하여 각 행정구역의 열섬현상강도 차이의 원인을 살펴보았다. 분석결과 UHI Intensity는 행정구별, 행정동별 특징 및 주변 환경에 따른 차이가 존재하며 행정동 단위에서 차이가 더 크게 나타났고 구의 UHI Intensity와 구에 속한 동의 UHI Intensity분포 또한 차이가 존재하였다. 선형회귀분석결과 평균 풍속, 개발정도, 토양보정식생지수(SAVI), 정규화시가지지수(NDBI) 값이 행정구역별 열섬현상강도 차이를 발생시키는 유의한 변수로 나타났다. 토양보정식생지수와 정규화시가지지수는 행정동단위 까지 그 값의 차이가 존재하는 것으로 나타났으며, 열섬현상 완화를 위한 바람길 환경 조성은 행정동 차원에서의 시행이 필요한 사항이다. 따라서 토지피복 개선 계획, 바람길 조성 계획, 개발지역에 대한 벽면 녹화계획 등 열섬현상 완화를 위한 사업들은 행정구 단위의 차이만을 고려하기보단 구안에 속한 행정동까지 고려할 필요가 있을 것으로 판단된다. 본 연구의 결과는 도시 도시열섬현상 완화를 위해 행정동 단위에서의 분석의 필요성과 고려해야할 변수를 도출하여 향후 도시 열환경 설계 및 정책 개발 시 접근방향을 제공할 것으로 기대한다.

Since 'Hanok Expanse Support' has been started in Seoul, its target was expanded from renovation to new construction and from 'Hanok District' to all area in Seoul. The newly built hanok with Hanok Expanse Support had to follow the standards about the form of the hanok and adapt to modern lifestyle. However, the newly built hanok were planned with 'kan' since it retained the traditional wooden structure. So their composition of kan were considered to be influenced by the standards of each district and modern lifestyle. Therefore the aim of this study is to understand the architectural characteristics of newly built hanok in Seoul since 2000 focusing on the kan composition. Because of the differences in site conditions and the district unit plan, newly built hanok in Hanok District have more limited changes than Other District. However, kan is composed variously in horizontal and vertical ways to make the most space according to site conditions and most of the newly built hanok have opened courtyard rather than closed courtyard layout. With kan composition in various directions and kan added under the eaves, kan is highlighted in form. On the other hand, the composition of kan as an interior spatial element has changed and weakened because the lifestyle has changed compared to the traditional hanok and the 20th century urban hanok. Also the regular kan composition of Mom-chae and Nalgae-chae has changed. And kan is divided regardless to the wooden structure. Also, with the added kan under the eaves the main kan is dismantled inside. This paper indicates that although there is an undeniable premise that the case is restricted to hanok received Hanok Expanse Support on the condition of following the standards of the form of hanok, it is a part of the transitional changes that hanok is experiencing.
