The purpose of this study was to identify the influence of living factors on TVOC(Total Volatile Organic Compounds) concentrations and personal factors to reduce the Sick House Syndrome for newly-built apartments. The field measurements of TVOC concentrations were made totally 30 times(5 times per one subject house) in six apartment units in which residents recently moved. Those apartments authorized its business approval before May 2004, the Act of Indoor Air Quality Management for multi-use facilities. The Questionnaire surveys of residents' subjective responses on the Sick House Syndrome were carried out in 2nd measurement of each house. Respondents consisted of 20 residents living in the measured houses. The findings were as follows: The TVOC concentrations of the measured subject apartments ranged from about 1/10 of the recommended standard for multi-use facilities($400{\mu}g/m^3$) to up to 90 times as high as the standard. Since then, the Recommended Standard of Indoor Air Quality Management for newly-built apartment house was announced in December 2005. In accordance with this standard($2390{\mu}g/m^3$) it ranged from about 1/100 to up to 15 times as high as the standard. The subject house whose TVOC concentrations reduced below the recommendation standard in the shortest period had the largest amount of ventilation (all the windows were open for ventilation in the past three months) among all measured houses. The reason of another house whose TVOC concentrations were much higher than the rest was fronted with new furniture in the room. There turned out to be no apparent relations between the TVOC concentrations and the residents' individual responses of Sick House Syndrome. The responses were serious in those who stayed in their new houses for a long period or had disease like allergy. It's recommended that they should open all the windows for at least three months for ventilation in newly-built houses, and it would be better to avoid remodeling than needs be.

Life-long housing refers to housing units whose performance is certified by the head of a Life-long Housing certification authority with respect to durability, variability and ease of repair. Since life-long housing should be able to meet residents' demands for changes in living space, the space of the housing should be able to be varied by using a dry construction method, instead of a wet construction method. For life-long housing to be approved, the installation of infill systems that life-long housing certification standards is needed. At present, apartment houses are being constructed only in accordance with the general rating, which is the lowest rating in the life-long housing certification system. The reason for this is that, since the infill system was created, it has not yet been actively used due to a rise in construction costs when infill products are utilized. In this regard, this study seeks to propose ways to optimize infill usage and create scenarios that can minimize the costs of life-long housing construction, taking into consideration variations in construction costs based on the characteristics of infill systems applied to housing.

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.

This study was intended to grasp the housing unit plan which the residents preferred. The subjects were 100 housewives who lived in 85$m^2$ sized housing units in the New Apartment Complex, Gimhae. First, four elements of unit plan were selected on the basis of the results of the POE which was carried out for the same subject the size of master bedroom and living room, the openness of dining/kitchen from living room, the openness of living room from entrance, and whether or not a bathtub or a shower booth is in bathroom. Then, eight design alternatives of unit plan made by combination of these four elements according to orthoplan were visualized by computer media. This visualized tool was used for collecting data. The results of the study were as follows: The important determinants of the residents' preferences for unit plan were the size of master bedroom and living room and the openness of living room from entrance. The residents preferred the unit plan which living room was large and the view from living room to dining/kitchen was open. Also, the important elements were different according to the characteristics of the residents. Therefore, the housing alternatives which are flexible and optional would be desirable.

Construction projects, including housing, are carried out over long periods of time. According to changes to the construction period, the cost of input materials and wages also changes. Therefore appropriate management is important in order to minimize cost risks caused by fluctuations in prices. In Korea, housing units are usually sold in lots prior to construction completion. Therefore, careful management of input elements such as materials and equipment that are sensitive to price fluctuations is very important. This study deals with how the price fluctuation of materials, labor, and equipment influences the change of housing cost and seeks a way for cost management through identifying key resources sensitive to price fluctuation. As a result, a change to the housing cost index multiplies depending on cost changes of materials and labor together. Labor costs are a major factor on the housing cost index. In addition, certain types of materials and labor input to housing construction greatly influence price fluctuations. Thus, it is found that managing those main cost factors is the key for effective cost management.

This study empirically investigates the degree of physical exclusiveness of multi-family housing estates and its socioeconomic effects. By combining various physical elements devised to blockade and control the entrance to the estate as well as housing units, it constructs the index to quantify the degree of physical exclusiveness for the multi-family housing estates of more than 300 households in Seoul. The statistics reveal that the degree of physical exclusiveness has increased over time and therefore, as a representative example, two-thirds of the estates are now equipped with barricade at the entrance, which often symbolizes 'gated community'. The estimation result of hedonic price model show that physical exclusiveness has a significant positive effect on housing price. The household survey data for the case study estates also demonstrate that the residents in the estate of higher degree of physical exclusiveness put a higher housing value on socioeconomic 'prestige' as well as 'community', beyond physical 'security', and have closer neighborhood relationship with the residents inside the estate. However, there is no significant difference in neighborhood relationship with the outside residents depending upon the degree of physical exclusiveness.

The purpose of this study is to grasp the spatial characteristic of the unit plan for a Super-High-Rise-Residence. This study is focused on the open air contact sides for a tower type Super-High-Rise-Residence. A tower type Super-High-Rise-Residence which has open air contacts from 1 to 3.5 sides differed in spatial characteristics of the unit plan for other apartment units. The current study analyzed 188 unit plans for the size of 40 pyong or larger in Seoul and the metropolitan areas which have been built since 1990. Open air contact side was classified as under 2 sides, 2 sides, and over 2 sides. The unit plan which belong to each open air contact side was Investigated according to the location of public area, the relationship between livingroom and master bedroom, and a method of entry to the master bedroom. The results of this study are as follow: According to increase open air contact sides is changed the location of public area in unit plan from an typical arrangement to various arrangement. Also the relationship between livingroom and master bedroom becomes loose and in a method of entry to the master bedroom increase an indirect approach through other room.
