The purpose of this study is to find the characteristics of space utilization and the problems that follows after converting in a new developmental residential area. This study used the content-analysis method and analysis was made on the floor plans for 95 different conversion cases. Above all, 190 unit plans (the unit plans for conversion before and after) were analyzed. The results of this study were as follows; 1) There were 8 types of conversion according to such usages as residential, commercial and residential-commercial buildings. 2) In the case of conversions, from residential to commercial, there was a tendency each floor was integrated to exclusive use for commercial or commercial with small portions of residential usage. And in the case of conversions from commercial to residential, there was a tendency that all space of each floor were changed to exclusive usages for residential purposes. 3) In case of usage conversion from commercial to residential, there were constraints for balcony installation, because of its original lot-structure and building equipments. Also, when the basement was converted for residential purpose, there was no possibility for an extra lighting or ways to ventilate the area.

In general, the decay of the residential district has been considered a phenomenon of old towns. But now it has become a problem of new development areas too, which have been a cause of the decay of old town. This study aims to investigate the decay of the residential district in the new development area. The survey site was Dunsan, a town-intown of Daejeon metropolitan city. The findings were as follows (:) 1) even in the new development area, a high level of vacancy ratio was evident. ; 2) among the buildings above ground, 1st floor showed the highest vacancy ratio, which means the 1st floor was allotted to too many commercial facilities relative to the buying power size in this district. ; 3) there were many conversions in response to the decay of the district, from residential to commercial, and commercial to residential. ; and 4) the allocation of each type of conversion showed a spatial pattern.

The The purpose of this study was to compare of the characteristics of floor plan and housing satisfaction with two types of housing units, 2-bay and 3-bay. Two bay housing unit is one that two rooms, a bedroom and a living room, are in the front side of housing unit, and 3-bay is one that three rooms such as two bedrooms and a living room are in the front side. 15floor 85m$^2$-sized plans of housing unit were analyzed. There were differences in the arrangement of entrance, balcony, and bathrooms between two types of housing units. The subjects were 200 housewife who lived in 2-bay housing unit and 200 ones in 3-bay one. The residents who lived in 3-bay were younger, higher education and income level, and more home ownerships than ones in 2-bay. The residents in 3-bay were more satisfied with their housing unit than in 2-bay.

Cheongju has been a continuously expanding city due to housing development and new town construction since the 1980s. With time, many urban problems have arisen, such as commercial decline, and degradation of the residential environment in inner city. To revitalize the inner city, this study proposed some planning strategies through the linkage of separated urban regeneration projects maximizing its effectiveness. Therefore, firstly, this study selected the target area in the inner city and identified the cause of the declination and deterioration pattern. Secondly, the main issues were derived by reviewing the locational characteristics and the potential of the target area. Finally, four strategies and detailed projects were suggested for the target area for revitalization of the inner city. Although the effectiveness cannot yet be verified due to its under realization, the results derived from the citizen's participation are having a very important impact and they can be a useful reference for similar planning.

This paper offers a brief overview of the historical implications of residential segregation in Busan, Korea. It first reviews the history of residence from the early 1900s to the present and the transition of residential boundary of the City of Busan. It then considers the characteristics of residential segregation and the important factors in it. The social class of pre-industrial society led the inequality of residential areas around the Eubchee. The existed Korean residential areas were separated by newly built-up residential areas in the Japanese colonial era. After the liberation from Japanese Rule and Korean War, rapid population growth made considerable slums across the City of Busan. These slums were an important factor to segregate residential areas from prosperous areas ever afterward. The socio-economic status has related to residential segregation through the formation of differential housing classes since 1990s. The historial analysis of these periods will offer an insight into how the dominant factors lead residential segregation in a specific period by promoting a more socio-economically integrated society.

우리나라의 최근에 개발된 신도시나 신시가지를 제외한 대부분이 합류식 하수관망으로 구성되어 있다. 이에 따른 초기강우시 도시 인접하천으로 유입되는 유출수가 수질오염을 가중시키고 있다. 분류식 하수관이 설치된 지역이라도 강우에 의해 도시지역 노면에서 우수관을 통해 하천으로 배출되며 유출수 자체도 오염물질 농도가 높고 유해물질까지 함유하고 있는 경우가 많다. 그러므로 도시하천에 대한 종합적인 수질관리를 위해서는 점오염원뿐만 아니라 초기강우시 도시 유출수의 수질 및 오탁부하량 등 비점오염원에 대한 기초조사 및 해석이 선행되어야 한다고 판단된다. 따라서, 이 연구에서는 도시하천의 초기강우에 의한 유출수의 수질특성을 분석하기 위하여 홍제천, 중랑천, 남가좌배수구역 및 군자배수구역 등 4개 도시유역에서 직접 시료를 채취하여 각 수질항목에 대하여 분석하였다. 수질분석은 환경오염공정시험법이나 표준시험법에 준하였고, 현장에서 실측이 가능한 항목들은 현장에서 측정하였으며, 나머지 항목은 시료를 즉시 실험실로 운반하여 분석하였다. 홍제천은 1996년 8월부터 1997년 9월까지 5개 강우사상의 자료를 분석하였고, 중랑천은 2001년 5월부터 2005년 4월까지 7개 강우사상, 남가좌배수구역은 1995년 7월에서 1997년 9월까지 5개 강우사상, 그리고 군자배수구역은 2005년 4월부터 2007년 9월까지 11개 강우사상에 걸쳐 수질분석을 실시하였다. 분석된 수질자료를 이용하여 도시지역의 초기강우에 의한 초기유출수와 수질의 관계를 분석 비교 하였으며, 또한, 초기유출수에 따른 비점오염원별 상관성을 분석하여 유량 측정을 통하여 보다 손쉽게 총 오염부하량을 산출 할 수 있도록 비유량과 SS, $BOD_5$, COD 등의 수질성분간의 상관계수와 회귀식을 도출하여 이들 상관식으로부터 유량변화에 따른 수질성분의 예측에 활용토록 하였다. 그러나, 외삽구간의 유량에 대한 수질 예측 결과에는 큰 오차가 있을 수 있으므로, 보다 다양한 유량에 대한 수질관측자료로 보완된 상관식의 개발로 극복되어질 수 있을 것으로 판단된다. 이 연구의 성과는 도시유출에서 수질과의 상관성과 도시하천의 유량 수질관리에 유용한 자료로 활용될 수 있을 것으로 판단된다.

A planned access method on constantly-changing-community unit plan changes and develops based on the periodical situation and also plan theory. In this research, it is to present the link between the theory of complex city change and the plan factor of it, and to show how Korean residential complex plan has changed as time passed and how new concept of city plan came up and by applying new methods how can this affect our real world and the past plan. In the phase of analysis, it analyzed the flow of 'community unit plan' and its theory and investigated the factor of compositional space and built a analysis frame. The factors of community unit plan are space structure, size and shape of block, population, distribution of facilities and movement system. It chose the place that can represent the flow of community unit plan trand and that indicates the obvious development leading to Jamsil (1975), Gwa Chun (1980), Mok Dong (1983), Sang Ge (1985), Ilsan (1989), Dong tan (2001) and Eun Jung (2003) total of 7 places. And to compare a similar size of the city, it selected a small community unit. Based on the result of theoretical study and prior research, it can be said that the space composition style has change from a whole complete complex area to a linked-cross over community unit and the access of urban level was on set. Also, a pedestrian walking area was secured and the dense of building structure and pleasant environment wanting need was in balance. For facility plans, the usage of facility and functional change brought change of type, size and disposition. The walking area for pedestrian became a huge matter. Therefore, market, education, public facilities and green system collaborated to co-build a whole community unit and activated the walking environment. Also, public transportation, environment friendly city organization was built.

A newly developed rainwater harvesting (RWH) system reliability model is evaluated for roof area of buildings in Haeundae District of Busan. RWH system is used to supply water for toilet flushing, back garden irrigation, and air cooling. This model is portable because it is based on a non-parametric precipitation generation algorithm using a markov chain. Precipitation occurrence is simulated using transition probabilities derived for each day of the year based on the historical probability of wet and dry day state changes. Precipitation amounts are selected from a matrix of historical values within a moving 30 day window that is centered on the target day. Then, the reliability of RWH system is determined for catchment area and tank volume ranges using synthetic precipitation data. As a result, the synthetic rainfall data well reproduced the characteristics of precipitation in Busan. Also the reliabilities of RWH system for each of demands were computed to high values. Furthermore, for study area using the RWH system, reduction efficiencies for rooftop runoff inputs to the sewer system and potable water demand are evaluated for 23%, 53%, respectively.

Urban land use planning is the most important core-part, and it is the start and synthetical plan of the other part, in the urban planning. For the desirable urban land use planning draw out the spatial locational character and change of urban land use. The propose of tills study is building methodology of Parcel-based Urban Land use Information Svstem(P-bULlS) and it's apphcation methodology that can be used urban planning or land use planning. To this end, each and all of the land parcels of Kangnam area was analyzed. P-bULIS should be able to easily analyze the spatial locational character and change of land use in the region. And It should be able to the qualitative, quantitative and spatial analysis, and spatial multi-variate statistical analysis can be done at relatively low cost by linking the software of statics to P-bULlS.
