The background of this study is to examine the structure of housing price of which characteristics are not equal but hierarchical in the apartment complexes. So, the purpose of this study is to analyze the influences of apartment complex characteristics on the housing price within the same regional boundary by HLM. The data used as dependent variables were the market prices of 938 units from 29 apartment complexes by stratified sampling. The 2nd level independent variables is the Housing complex characteristics which are composed of the housing complex & locational variables and the 1st level independent variables are the unit characteristics. The results are as follows. First, the first model shows that the 2nd level variables explains 68% of the housing prices. Second, the influential variables of the 1st level unit variable are 'dwelling exclusive area', 'floor of dwelling' and 'direction of dwelling'. Third, the influential variables of the housing complex variables in the 2nd level are 'lot area', 'the building-to-land ratio', 'the number of unit', 'the number of parking lots per unit', 'Green space area' and 'open space area per unit'. The last, the influential variables of the housing locational variables in the 2nd level are 'distance to subway and park' and the number of school and park within a radius of 1km.

This study focused on the possibility of reducing the cooling load through the change of micro climate in the outdoor space during summer season. This study proposes an efficient planning model by comparing the effects of urban heat island mitigation through wind path planning, outdoor space vegetation, and exterior material change by using the basic model of the street-oriented block housing proposed in the previous research by the same author. As a result, the most effective wind path planning strategy in the street-oriented block housing was the change of the air flow through the mass height adjustment. When the tall building masses were staggered and arranged in a balanced manner, the overall wind environment could be improved. The greater the height difference between low and high masses, the better the air flow was shown. It was also important to arrange the building masses so that the inlet of the main wind was open and to allow the external space to connect to the adjacent block to create a continuous flow. The change of outdoor space vegetation and flooring, and the formation of wind paths through the opening of lower part also showed the effect of heat island reduction. In addition, the change of PMV in summer was the biggest influence of shadow by tall building mass. Attention should be paid to the fact that high-albedo exterior materials are adversely affected by multiple reflections in dense street-oriented block housing. The use of albedo of the exterior material showed that it is necessary to pay attention to apply in the high density block housing. This is attributed to the rise of the temperature due to the absorption of energy into the low-albedo flooring, where the high-albedo exterior causes multiple reflections.

도시의 온도상승의 주요 인자 중 하나가 도시부 도로이다. 본 연구의 목적은 도시도로 녹지가 표면온도의 저감에 영향을 미치는 요인을 파악하는 것이다. 이를 위해 서울시 도로 18개 지점을 선정하여 도로횡단구성요소(주변토지이용, 차도, 보도, 식수대, 중앙분리대)별로 열화상 카메라로 표면온도를 조사하고, 도시도로 녹지 면적을 측정하였다. 도시도로 녹지의 도로 표면온도 저감에 미치는 영향을 분석한 결과 도로 주변토지이용이 녹지 및 오픈스페이스일 경우 도로온도에 미치는 영향이 가장 크며, 식생중앙분리대의 면적, 식수대의 면적 순으로 표면온도를 저감시키는 것으로 나타났다. 도로주변 뿐만 아니라 도로설계의 구성요소 내에서 식수대, 중앙분리대 등의 녹지면적 증가는 도로의 표변온도 저감에 영향을 미친다. 도시의 고온화현상을 완화하기 위하여 도시도로 녹지 면적을 증가시키는 것도 한 방편이다.

The purpose of this study is to propose rational methods in order to maintain vegetation condition and soil environment based on the analysis of tree growth in relation to the soil environment, which is one of the most significant environmental factors on vegetation condition in urban parks and open spaces. The result of the study can be described as below;The soil on every study site had strong acidity. In particular, study sites around industrial district and central business district showed extreme soil acidity. Therefore, soil management system is needed in urban parks and green spaces around those areas. Among Cambium Electric Resistance classified by locations of urban parks and open spaces, one in the costal area was the lowest. The Cambium Electric Resistance in the industrial area was the highest. Therefore, soil condition and locational environment in the industrial area are highly related to the Cambium Electric Resistance. Among the factors, which affect Cambium Electric Resistance in different locations, inorganic content was found to be the main factor in all of the study sites. Inorganic content was an important factor to the Cambium Electric Resistance in study sites located in industrial and central business districts. In the study sites located in costal area, Soil acidity was found to be other important factors that affect Cambium Electric Resistance. To improve the soil acidity, soil buffering ability should be improved from activating microorganisms in the soil by using lime and organic material, Since it takes a long time to make a change in the soil structure, well planed maintenance system is required by mid-term or long-term plans.

Since 1960s urban streams in Seoul have been dried and polluted because of urbanization. So, these devastated urban stream environment need to be restored for the better life of residents. Since 1995 stream restoration project which is called Natural-Style Stream Project have begun. However, some projects focused on the restoration of park-style open space rather than restoration of stream environment. As a result there are some stream landscapes to be improved. Therefore, this study aims to investigate the current status of urban stream landscape after Natural Style Stream Project and to propose the alternatives for the urban stream landscape improvement. The study site is Yangjae stream, Seoul.
