본 연구에서는 기존 16층 이하 공동주택의 화재취약성 및 피난시설에 대한 문제점을 평가하기 위하여 공동주택에서 화재발생 빈도가 가장 높은 주방화재를 가정하여 CFD 모델링을 이용하여 화재위험성을 분석하였다. 그 결과 주방에서 발생한 화재는 거실로 연소 확대되면서 빠르게 다른 침실로 연기가 확대되었으며, 화재발생 세대 출입구에서 90초에 열에 의한 영향 온도인 $60^{\circ}C$를 넘는 것으로 분석되어 초기에 화재발생을 인지하고 피난이 이루어지지 않을 경우 피난출구가 막혀 큰 피해를 줄 수 있을 것으로 판단된다. 그리고 기존 피난시설에 대한 문제점을 극복하기 위해 본 연구에서 제안된 피난대피시설의 경우 발코니에 설치되어 있다가 외부로 돌출되는 형태로 온도 및 복사열유속에 의한 안전성 평가 결과 세대 내의 다른 지점에 비해 안전성이 확보되는 것으로 분석되었다.

The purpose of the study is to investigate the characteristics of the elderly housing preference and spatial usage to plan floor space of the elderly housing by the respondents of the ages 50 to 79. Based on the result of the study, it is suggested that the elderly housing should be located in regards to social environmental factors rather than natural environmental ones. There are differences in preference for the space planning of housing units such as the number of rooms and bathrooms, and floor space depending on income level, so the housing should be differently planned to accept the difference of preference. On the other hand, there is not notable difference in furniture preference for each space. In the characteristics of spatial usage according to behaviors, high-income respondents demonstrate the characteristics of spatial usage in accordance with a western lifestyle. Thus, behaviors such as sleeping, watching TV, resting, reading, conversation, and receiving guests, occur using such things as beds, sofas, and dinning tables. On the other hand low-income respondents show a mixed western and traditional lifestyle. Thus many behaviors are done on the floor of bedroom and livingroom in addition to using furniture such as a sofa and chairs. Therefore, the way of spatial usage has to be reflected in the floor space planning. At least floor space of the provided rooms should be planned to accommodate the behavior of the elderly even though all of the rooms preferred can not be provided.

As the increase in quantity of apartments has been stable, consumers' needs in housing quality become more diverse. According to the changes in the tendency of residents, construction companies has developed brands of apartment buildings with the concepts of LOHAS, well-being, ergonomics, ubiquitous. However, these trends has been focusing on the Capital area, and becoming fixed and typical in the way of delux quality, large-sized houses and a healthful residence. For that reason, this research is about survey on the needs of the local apartment residents, especially in Daegu. This analysis of their preferences will furnish basic data and offer possible interior plans to building companies making inroads into the Daegu apartment market. This research is based on the questionnaire forms which had been collected for two months(in Aug.-Oct.) of 2005 in Daegu and the amount of the samples is 135. All of them are the residents of the apartments where they moved in after 2000. The contents of this research include the evaluation of plane composition and practicality, interior finishing and design, and spaces for items. The results of this research show that the interior design and finishing materials of apartments in Daegu should be improved and the drainage and uncleanness of bathroom also need to be considered, much like the results of Seoul area. However, regarding the higher age range and life stage, the bedroom 2 needs to be planned for a study and the design of livingroom is prefered to be widely open. Besides, comparing with those in Seoul, the residents in Daegu demand that spaces for things (especially those in secondary kitchen and dress room) be more organized and convenient.

Since collective houses are started to be supplied, the housing market has been transformed from supplier to demander oriented, and various type with same area of unit households have been deigned and started to be distributed. It can be expected that such transfer phenomenon would be continuously sped-up, and unit household will be more subdivided and varied. Thus, we analysed and studied the planes with subject of unit households in national housing scale ($85m^2$) that is treated as supply standard and has biggest volume in construction by Korean housing corporation. The analysing method is investigating the area of each room within unit household, calculating their minimum, maximum, and average values, studying the efficiency of unit household plane according to the structure of each room by comparative analysis these values, and analysing changing matter by investigating any change of each room area. The analysing results of which are followings. At first, number of BAY on face is increasing. Second, allocation of each room has been vary. Third, area ratio among bedroom1, livingroom, diningroom/kitchen become similar. Fourth, the area of diningroom/kitchen become somewhat bigger. Fifth, the space for passage way is efficiently allocated. Sixth, service area is reduced, Seventh, stereotyped phenomenon Is appeared. Based on many studies so far, any improvements of unit householder in national housing scale are followings. First, in terms of forming style, unit householder in national housing scale is unfolded in various way though, the form of each room is not more than typical style. Second, it shows stereotyped phenomenon. Especially, bathroom 1, 2 show stereotyped feature in terms of their type and area across entire research years, also LDK allocation method is stereotyped, as well as stereotyped trend in bedroom 2, 3, allocation for 4 BAY type.
