Purpose: Urban heat island and Heat wave raise urban temperature and create damage of human life. Growing up as quantitative supply to solve shortage of housing, Urban residential area in Korea have a low rate of nature surface and heavily population makes temperature rise. Most houses in the declined residential area are multi-family rental housing and have many factors congesting housing environment such as narrow in-between space, outdoor staircases, walls and semi-basement floor, which make thermal environment getting worse. Most of the residents in this area are small tenants vulnerable to climate change adaptation, This damage is expected to be even greater. This study focus on multiple dwelling in urban residential area prone to temperature rise and draw temperature adaption method that can apply to multiple dwelling.

As a lifeway and social change, the neighborhood build up around elementary school based on Perry's Neighbourhood Unit becomes change. Elementary School does not function as a center of residents' activity or community any longer. Activities occurred near the school move to the community streets that many facilities are distributed to, while utilization of facilities near schools becomes lower. On the bases of the current states, this study aims to draw a practical neighborhood center of residential areas by case study. The research is being mainly about low-rise residential areas in Seoul which includes one elementary school at least. In order to deduct the center of neighborhood, the survey takes two steps. At the preliminary survey, conduct the observation and do an interview to investigate awareness and actual status. Also to analyze practical center, do a main survey about land value, pedestrian volume, distribution of public transit and facility density. The research result shows that there is another activated center street not nearby elementary school in every case. This study assumes that the neighborhood center is not limited around elementary school and could variously build up by circumstances. It has significance that we present a question about the traditional theory and also could be references of the future city maintenance in the long term.

The purpose of this study is for investigating characteristics of changing residential density and relations between housing supply and redistribution of population in Daegu. As a result, the following conclusions could be made. First, land development and housing supply have important effect on distribution of population and changing residential density in Daegu. Second, according to massive site development to meet the housing demand in suburban area, the suburbanization has begun and build-up-area grows faster, so centre of gravity of residential density increasing rate has moved to the suburban. Third, the inner district and the district near urban centre will need remodelling or redevelopment project in the near future.

The purpose of the this study was to provide the basic information about the formation background of urban squatter and their housing state in Korea. This study was progressed on the basis of socio-historical point of view from after the Korean War to the present time. Therefore, this study considered the meaning of housing for urban squatter in the Korean housing history. For this study, the formation background of urban squatter was divided into five periods. The first one was the period of the policy on the mass migration (1955-1960) after the Korean War. The second period was the period of reproduction of deteriorated residential area (1960-1970) for the continuing mass migration policy. The third was the period of disbanding of deteriorated residential area (1970-1980) for redevelopment. The forth period was before the IMF (1980-1997) broke up the deteriorated residential area. The fifth period was after the IMF (1997-) produced the new poverty due to the unemployment and the business failure. Thus, such social change increased the number of urban squatter and created the new type urban poor.

The use of land cover was sharply changed during 1975~2007 in the Kyungan watershed $(561.12 km^2)$. The changes occurred over an area of more than $227.65 km^2$ during the overall period at changing rates of 1.04% per year for water area, 1.79% per year for residential area, 2.99% per year for bare area, 3.03% per year for wetland area, 3.04% per year for grass area, 0.87% per year for forest and 2.32% per year for agriculture area. Water, residential, bare and wetland areas increased, while grass, forest and agriculture areas decreased during the last 32 years. BOD concentrations of representative sites for each sub-watershed continuously increased until the early 2000s as residential area increased with the highest discharged load, but decreased after the mid 2000s except upper Kyungan watershed. Such decline appears to be associated with the planning of Total Maximum Daily Load management for Gwangju city and expansion of waste water treatment plant. It is necessary to control land use/cover changes of the upper watershed and to prepare appropriate watershed management system for improvement in river environment including water quality, stream flow and bio-diversity.

The population is concentrated in the metropolitan areas in Korea, and low-density residential areas are transforming into high density residential areas through redevelopment to meet this demand. However, large-scale redevelopment in a short period of time has a negative impact on the urban climate, such as generating a heat island effect due to the reduction of urban green areas. In this study, the change in surface temperature from 2013 to 2022 in the redevelpment areas of Godeok-dong and Dunchon-dong, Gangdong-gu, Seoul, was analyzed using Landsat 8 satellite images. In the Godeok-dong area, the difference in surface temperature was analyzed for the target redevelopment area, forest area, mixed forest and urban area, and low density residential area. In the Dunchon-dong area, the difference in surface temperature was analyzed for the target redevelopment area, forest area, and low density residential area. The difference in surface temperature was analyzed through multiple regression analysis conducted yearly over the three different stages in redevelopment period. The results from the multiple regression analysis show that in both areas, the land surface temperature of target redevelopment area was higher than that of the forest area and lower than low density residential area. It can be seen that these results occurred because the low-density residential area in Godeok-dong and Dunchon-dong had a lower green area ratio and a higher building-to-land ratio than the target redevelopment area. The results of this study suggest that even if low-density residential areas are transforming into high-density areas, adjusting the management of green areas and building-to-land ratio can contribute to lessen urban heat island effect.

This investigation is to question as to whether and how much urban residential superblocks have changed the uses of facilities, as compared with original zoning plan. The difference between the original plan for 'land use' in 1960's and current 'building uses' has been examined on six superblocks in Seoul, and the reasons for change were analyzed. Investigation results are as follows: As the original urban planning was intended for use-purification by the subdivision of zones in a superblock through zoning, current buildings uses are different from the land-use. Commercial facilities are located in residential zone along community paths because of the necessity, and business buildings are placed on the appropriate-sized lots in the middle of residential blocks, due to the need of small and low-rent offices. Also, different types of residence have been built on convenient locations in commercial zone to meet various housing needs. In conclusion, the current zoning system plays a role of controling the volume of buildings rather than the use of land. Therefore, mixed use of land, not functional separation, becomes a natural phenomenon taken place in the contemporary cities, and it is high time to adopt a mixed-use zoning system.
