This study conducted a survey on the time serial change in the aging ratio and population structure in new towns and their housing complex of Korea and Japan, and revealed the differences in the factors that affect the aging ratio in new towns of Korea and Japan through a comparison of the housing provision of housing complex with a high aging ratio. Rapid aging is underway around the housing complexes that were developed in the beginning of Tama new town in Japan. Agingtends to increase in proportion to the opening time of the housing complex. Rental housing residents of early migration households showed rapid aging because they had generation separation early due to narrow housing. On the other hand, Bundang new town maintains a lower aging ratio and speed than Seoul and Seoul metropolitan area due to the constant influx of student population. On the other hand, aging is more likely to increase in large houses due to the depression of the real estate market.

The primary purpose of this study is to provide the managerial guidelines for the comprehensive apartment improvement planning. This plan will consider the time-serial apartment management plan. Through a questionnaire survey, residential satisfactions and demands on apartment units, apartment building and site amenities were investigated. Based on the statistical analysis, residents' demands were assessed. The resident groups were categorized into the three groups considering the apartments' life span where they were living. The results from the statistical analysis were finally compared with the long-term apartment management plan demonstrated in the Housing Code of the Ministry of Construction and Transportation. The major findings of this study were as follows. First, residential satisfaction on the equipments in apartment units was higher than that on the unit plans. Residents' satisfaction on the communal facilities in apartment sites was lower than that on the other factors. Thus, apartment unit plans and communal facilities in sites need to be improved. Second, though we had the three residents' groups, for the results of the residential satisfaction, the groups were divided into two groups: 'less than 10 years group'and 'over than 10 years group'. Considering the residents' demands for the apartment improvement according to the life span of apartment complexes, the habitability factor was demanded by 'the less than 10 years group' and the safety factor by 'the over than 10 years group'. Compared the residents' demands for apartment improvements with the long-term apartment management plan demonstrated in the Housing Code, the improvement cycles demanded by residents were shorter than those in the code. Thus, the management plan in the code should be reconsidered.

The purpose of the study was to investigate the characteristics of energy use behaviors and energy saving consciousness of multi-family housing residents. The energy referred to in this study includes electric energy, heating energy and water usage. This study was conducted from a survey carried out in Seoul and Gyeonggi-do. The results of the study are as follows: First, among the survey questions, the only positive energy saving behaviors shown by the occupants was turning off the lights and the television, and in the use of kitchen appliances; it could therefore be concluded that, in general, energy saving attitude and consciousness were not sufficient to reduce energy consumption. Second, the results showed high mean scores for the behaviors which were easy to control, such as turning off lights and televisions, and low mean scores for the behaviors which required extra effort to completely cut off electricity energy such as pulling out the plugs of electronic appliances. Third, it was found that the occupants generally showed the tendency to save heating energy. However, in cases where the occupants were required to continuously and directly experience indoor temperatures, they expressed passive attitudes toward saving energy. Fourth, they showed wasteful attitudes toward water usage by leaving the tap running when taking showers and washing their faces. Fifth, while they showed a strong energy saving consciousness, they also showed a passive attitude about putting this into practice; there was therefore some gap between attitude and behavior. Lastly, among the socio-demographic factors, age and family lifecycle were very important factors affecting energy use and energy saving consciousness.

In increasingly competitive market conditions, domestic construction companies are struggling to secure a competitive edge by increasing consumer satisfaction. In these circumstances, a greater emphasis needs to be put on providing an upgraded level of quality in the area of addressing defects to the satisfaction of customers, which is considered to have a great impact on customer satisfaction. This empirical study of the relationships among service quality, customer satisfaction, and repurchase intention aims to provide basis data for increasing service quality, particularly in dealing with the defect issues facing construction companies. To this end, a literature review was carried out on the concept of service quality along with defect issues, and customer satisfaction and influential factors were identified. Building on these foundations and findings, a survey was administered to residents in housing dwellings such as apartments. The results of this study are expected to heighten awareness of the need for increased service quality, which may have a critical influence on customer satisfaction and repurchase intention, and will thereby contribute to enhancing competitiveness and other aspects of the current construction industry.

In this study, indoor thermal environment, resident behavior of operating cooling device, and thermal comfort vote are investigated at the living room of apartment during summertime in Seoul. Based on the results of the investigation, indoor air temperatures that residents turn air conditioners (especially for cooling load in this research) on and off were found out. The relationships between outdoor weather condition and the number of days using air conditioner, and whether operating patterns of the devices were also found out. The acceptable thermal comfort zone is figured out from these results, and this research is expected to contribute to the development of household air conditioner. The results can be summarized as the followings; Residents turned the air conditioner on at $29.76^{\circ}C$ of indoor air temperature, and $28.89^{\circ}C$ of $SET^\ast$. And turned the air conditioner off at $27.31^{\circ}C$ of indoor air temperature, and $23.70^{\circ}C$ $SET^\ast$. Therefore, acceptable thermal comfort zone could be lied between these temperatures. If comfortable indoor thermal environment can be obtained with various architectural passive cooling techniques based on the results, energy consumption of cooling devices will be reduced.
