This study is to explore floor impact sound and sound insulation of reinforced concrete structure with void-deck slab system which combines polystyrene void foam and T-shaped steel deck plate. A void-deck slab system can effectively reduce the amount of concrete used and hence the mass of a reinforced concrete slab. Also void slab system has dynamically favorable for bending. Three-bay 2-story building was constructed as a mock up test specimen using void-deck slab system and floor impact sound was measured to valuate sound insulation performance. Light weight floor impact and heavy weight floor impact were investigated. Light weight floor impact pressure levels were 32dB, 28dB, and 29db at representative locations which are $1^{st}$ level in the floor impact sound insulation performance grading system. The heavy-weight floor impact pressure levels were 44dB, 45dB, and 43dB at representative locations which are $2^{nd}$ level in the floor impact sound insulation performance grading system. Therefore void-deck slab system can be used in public housing apartment building in terms of not only effectively reduced construction materials but also floor impact sound insulation.

Public rental apartment has suffered social exclusion problem, stemmed from its closed planing for a very specific range of the disadvantaged population. Thereby, it has been recognized as a disliked residential facility. To alleviate this problem, various approaches have been tried such as ownership-tenant mixture, and different unit size mixture. The purpose of this study is to grasp the expected social relation among neighboring residents according to socially integrative planing elements such as ownership, unit size and family life cycle match. Thirty eight graduate students in architecture and housing field responded to the questionnaire which was specifically made to identify relations of 28 neighboring situations based on $2{\times}2{\times}2$ variable composition. Frequency, percentage and MDS(multidimensional scaling) were used to analyze data. As a result, the order of preferred matchy were identified. The match between rental/small/children group and ownership/middle/children group was turned out to be the most desirable while the match between rental/small/children family group and rental/small/elderly group was found the least desirable. Spatial representations of the relationships among 8 household types were delineated. In conclusion, the definite patterns of the favorable and unfavorable match were found. This result is expected to be used as a reference in developing a strategic match to promote the rental apartments social integration in Korea.

The objectives of this study were 1) to analyze the attitudes about Elderly Assisted Living(EAL), 2) to consider the policy implications for elderly communal housing according to socio-economic status(income, occupation and education). The survey was undertaken from August to September, 2000 in Seoul and Kyunggi-Do(Ilsan, Bundang). The data were analyzed by SPSS Window program. The major findings were as follows: Most of the respondents prefered to live in EAL(over 56%), under 10 units and desired to be serviced(housework.leisure medical program.meal service). The upper class respondents preferred high-rise apartment style inner city or suburban and prefered paid services in EAL. They would willingly to pay over 800,000 won for living expenses and more than 200 million won for buying their own EAL. The middle class respondents prefered 5 stories multi-family house style with common facilities as a number. And they prefered to common facilities opening to public if the quality of facilities were better. The low class respondents prefered 5 stories multi-family house style and prefered to live within 30 minutes apart from their families and friends. They would pay under 300,000~600,000won for monthly living expenses and under 100 million won for their own EAL.

건설프로젝트는 많은 불확정 요소로 인해 다양한 리스크를 가지고 있기 때문에 프로젝트 진행 과정에서 반복적인 성과측정은 중요하다. 그러나 현재 건설프로젝트에서 성과측정은 시공사 중심의 성과측정 및 성과관리가 이루어 져서 프로젝트의 진행상황에 따른 발주자의 능동적인 프로젝트 관리가 어렵다. 이에 본 연구에서는 실제 실행된 공공 아파트 건설공사의 공기 비용 데이터를 타입별로 분류하여 회귀분석을 실시하고 타입별 회귀식을 도출, 발주자 중심의 작업분류체계를 설정하고 이를 활용하여 이를 발주자 중심의 성과측정기준선을 제안방안을 제시하고자 한다.

In the study I analyzed the relationship between the characteristics of the user's residential environment and his or her use of openspace. I find out that there are little correlationship between building form and use factors. Also, there are no relationship between persons per room and use factors. Only the physical distance and the location of the building site is correlated with the use factor. In testing the hypotheses, I discovered very little to support the "physical deterministic" notion. I generally was not able to explain the behavior of open space users on the basis of the physical parameters selected to describe the user's residential environment. This, I believe, indicates that there probably are many other variables that play a more important role than those pertaining to the density and form of the residential environment. It is necessary to find out more variables affecting the use of openspace in the neighbourhoods, such as the charecteristics of user group. Also, it is necessary to apply the study to the other sites or the other cities in Korea to compare with the results.

In Korea, multi-housing in one of the most common types of residential space due to its easy management and convenience. In particular, south-facing plate-type(一) multi-housing has attracted a great deal of public interest because it consumes less energy compared with other types of multi-housing, making it advantageous from an energy-saving perspective. Although there have been many studies on the annual energy consumption of multi-housing in relation to building shape and area of window, there have not been sufficient research on the annual energy consumption of multi-housing in relation to individual units of the multi-housing. The purpose of this study is to propose a strategy for reducing energy consumption in plate-type(一) multi-housing, taking the units with the lowest energy consumption as the standard. The result, Standard Models's energy load was as 4000 ~ 5600kWh, and Passive Houses's energy load was less than Stand Models at the 1600kWh.

This study aims to examine and research the characteristics of apartment landscape at the street from a view that apartments are the major element of a cityscape and many apartments form a street today. Then, the subjects of this study were three sections consisting of streets in Namak New Town and the results were as follows. A streetscape is necessary to have identity under the unity(context) of parts which orient to "one as a whole". However, the subject apartments were not united(contextual) in layouts, roofs, and walls, whereas their facades appeared too united(contextual). Accordingly, to make a united(contextual) streetscape, the wall located in a boundary(a buffer zone) with public space which consists of a streetscape, building layout, building height, and roof forms need a design guideline which can have unity as a whole to connect with architectural design. On the other hand, the facade which was found too uniform should have a more active design guideline to elicit identity at unity.
