1989년 영구임대주택으로 시작된 공공임대주택 정책은 매 정부마다 새로운 공급유형을 도입하며 입주대상과 재고량을 확대하고 있다. 하지만 공공임대주택 사업주체는 공공임대주택의 적자누적으로 공급확대에 어려움을 겪고 있다. 본 연구에서는 장기공공 임대주택 재건축사업을 기존 장기공공임대주택사업의 누적적자 보전방안으로 제시하였다. 재건축사업으로 공급되는 분양주택 수익으로 누적적자를 보전할 수 있는 재건축사업의 용적률을 최소용적률로 정의하고, 장기공공임대주택 재건축사업의 특성을 고려한 수리적 접근으로 장기공공임대주택 재건축사업 최소용적률 수리모델을 제시하였다. 최소용적률 수리모델의 결정요인은 기존 장기공공임대주택 누적적자, 재건축사업 분양주택 토지면적, 단위면적당 분양가격, 단위면적당 사업비로 구성된다. 최소용적률 수리모델은 노후 장기공공임대주택 재건축사업의 건축규모에 대한 경제적 측면의 의사결정 지원과 도심지 내 주택공급 확대와 관련된 의사결정을 지원하는 이정표가 될 것으로 사료된다.

The purpose of this study is to investigate the change of wind environment for different building arrangement. In this study, we analyze outdoor wind environment on different building arrangement that take same floor area ratio using the CFD (Computational Fluid Dynamics) method. We do not consider the effect of temperature. Building arrangements of low density, different hight and a lot of green area will change the effect of wind environment. The eight different arrangements of buildings are studied in this paper. In these calculations, we know the different arrangement of buildings change outdoor wind environments. Especially, reducing the number of building and crossing the different height of buildings have a good kind of wind environment at the same floor ratio. We know that these arrangement of buildings to reduce the heat island phenomena on city plan.

This study aims to evaluate factors of floor structure influencing to the floor impact sound. For this reasons, we measured the vibration of floor and the floor impact sound in moment flame structure. The main results from this study are that slab area and thickness are critical factors of the floor impact sound and aspect ratio slab is not verified in flor impact sound.

This study aims to investigate the change in building density and residential environment after the reconstruction of decrepit public rental housing complexes formed in accordance with the Land Readjustment Project during the 1970s-80s. The results of this study can be summarized as follows: First, in terms of change in residential environment after the reconstruction, floor plans that were limited to two to four types and to small apartments measuring $42.9m^2$(13py)-$56.1m^2$ (17py) became varied, presenting 5-6 types of floor plans and various sizes of apartments. In particular, the reconstructed apartments were mainly built in a size smaller than 85($m^2$) and in the 3LDK floor plan and staircase-style unit architectural structure in order to reflect the lifestyle of residents. Second, in terms of change in building density after the reconstruction, the building coverage ratio did not change a lot, but the floor area ratio showed great change depending on the complex, ranging from a minimum of 2.9 times (Singdong Complex) to a maximum of 5.4 times (Eoyangdong Complex). Such change is attributable to the reconstruction policy that aims to improve the residential environment for original residents, secure economic feasibility and efficiency, and reflect the lifestyle of residents while incorporating dividends assigned to the existing housing project members as well as the maximum floor area ratio allowed by the regulation. Additionally, in terms of change in the number of floors and building density after the reconstruction, the former 5-story apartments were changed to apartments with 16-28 stories. Accordingly, the number of households in each complex has also increased by 20%. Third, according to the characteristics of parking facilities in terms of the size and density of parking spaces, former apartment complexes had only aboveground parking lots, not underground parking area. The newly constructed apartment complexes have underground parking space, and the parking-housing ratio is 1.1-1.3 cars.

본 연구에서는 최근 도시계획, 수자원 및 방재 분야에서 높은 관심을 가지고 연구중인 항공레이저측량기법을 활용하여 시가지의 건축밀도를 평가하였다. 먼저, 레이저스캐너인 LiDAR(light detection and ranging)로 취득한 표고자료로부터 DEM(digital elevation model)과 DSM(digital surface model)을 구축하였으며, 건물의 높이를 계산하기 위해 DEM에는 ZONALMEAN 필터, DSM에는 ZONALMAJORITY 필터를 적용하였다. 필터링 과정으로부터 계산한 층수와 현지조사의 층수를 비교한 결과 표준오차 ${\pm}0.199$층을 확보할 수 있었다. 또한 건물 연면적 레이어와 구획 레이어를 중첩하여 통계분석함으로서 도시 구획별 용적률을 제시할 수 있었다. 항공레이저측량 자료를 이용하여 계산한 용적률과 현지조사로부터 계산한 용적률의 비교 결과, 용적률의 표준오차를 ${\pm}2.68%$로 확보할 수 있었다. 따라서, 항공레이저측량 자료는 향후 토지이용계획을 수립하는 의사결정자에게 매우 유용한 자료를 제공해 줄 것으로 기대한다.

In the past thirty years, apartment house has been greatly developed and the housing supply has improved some degree. However, the fact is that interior space planning of apartment house still has a lot of problems. The purpose of this study is to research the change of interior room. The 160 examples of unit floor plan(40-85m2 i.e. 12.1py-25.7py) were selected and classified according to master bedroom type and living room area when was constructed by the city of Seoul and KNHC from 1970 to 1990. And then, the change of each area, size and ratio were analyzed and researched. The result of this research can be summarized as follows: 1. Size of unit floor plan was on the increase from 16.02py to 17.86py. 2. 2 bedroom type, master bedroom showed a rise of size and occupancy ratio. Living room grew larger than 1982-1991 for size and occupancy ratio. 3. 3 bedroom type, master bedroom was increased in size and occupancy ratio was reduced to 19.99%. Size of living room became broader than master bedroom and occupancy ratio(1972-1981) increased over 1982-1991. Through this analysis and research, this study is to provide the basic data for actural design process and to suggest future trend of apartment house.

The new apartments has been rapidly built through the outskirts of Cheong-ju city since the latter half of 1980's. So, the population decreased in Seong-an dong and Jung-ang dong which are located in traditional urban area of Cheong-ju. Also, residential areas became obsolete and residential buildings happened to be vacant and empty. For urban rehabilitation, the city authorities will construct the high-rise complex housings with stores in the traditional urban area. We have doubts about whether the rapid change of new housing construction is right or not. Therefore, It is necessary to give a correct diagnosis of the present state from urban atrophy, keeping this area sustainable with traditionality and locality. This study is to examine and analysis in detail distribution patterns and habitable floor area by house types in Seong-an dong and Jung-ang dong which are located in traditional urban area of Cheong-ju. The result are as follows; the residential buildings as the 2,680 houses(including detached and apartment houses) and the 804 shop houses are distributed with 3,484(67%) of the whole 5,183 buildings and form 28percent of the whole floor areas. A distribution and area ratio of houses to shop houses is irrespectively about 76 : 24percent. The average floor area is represented with $66m^2$/household and $28.5m^2$/person. It shows that a hollowing out of urban area has caused the surplus of residential buildings and floor areas.
