Nowadays, apartment is become a representative residential pattern. With these tendency, the concern about the apartment community in order to recover the dreary relationship with neighbors which is one of theproblem of the modern society and supplement of insufficien space of the community. However, this kind of community facirlities programs aren't individualized and it's operation is so paltry that it's actuasituation is no more than a simplesupply. Therefore, this study selected two cases of the apartments which are similar in size of number of families and construction year among winners of an excellent apartment award. I would like to focus on actual conditions of operation and use of the community facilities in management sides' view attempted a comparative analysis.

The primary objective of this study is to find out how housing characteristics have been changed through a recent move. Two hundreds and thrity households in Cheongju City who made a move during 1990 are selected for the empherical study. The findings show that almost families moved to the dwelling with similar or better conditions than the previous ones. The patterns of housing characteristics changed through a move play the role as an intervening variable between family characteristics and changes in housing satisfaction. Also, the results in general support the concepts of housing adjustment theory. There is a small number of low income families who moved to dwelling with worse conditions. Presumably constraints might prevent their housing adjustment behavior.

A pilot plant, which is simplified the hot water heating control system of a large scale residential building, is used to investigate the effects of control methods and operating conditions on the system performance and to compare control characteristics. Digital variable structure controller(DVSC) and digital PI controller are implemented to control the speed of the circulating pump for the pilot plant using PC. For the DVSC, a control algorithm is suggested, which using a nonlinear sliding surface and a PID sliding surface outside and inside of output error boundary layer, respectively. Smith predictor algorithm is used for the compensation of long dead time. The suggested DVSC yields improved control performance compared with existing DVSC using linear sliding surface only. the system responses with the suggested DVSC shows good responses without overshoot for various operating conditions and robust under external disturbances compared with digital PI controller.

Three-phase four-wire electrical distribution systems are widely employed in manufacturing plants, commercial and residential buildings Due to the nonlinear loads connected to the distribution system, the neutral conductor carries excessive harmonic currents even under balanced loading since the triplen harmonics in phase currents do not cancel each other This may result in wiring failure of the neutral conductor and overloading of the distribution transformer In response to these concerns, a cost-effective neutral current harmonic suppressor system has been proposed. This paper proposes an improved control method for the harmonic suppressor system under unbalanced load conditions The proposed control method compensates for only the harmonic components in the neutral conductor, and the zero-sequence fundamental component due to unbalanced loading is prevented from flowing through the harmonic suppressor system This remedies overloading and power loss of the system The experimental results on a prototype validate the proposed control approach.

This research is aimed to define how the depression, performing ability of IADL and muscular-skeletal pain of the Aged, according to their residential circumstance, sex and age, can affect the subjective health index and how all these are related and associated with. For the period of June 1 to July 31, 2000, in order to study and define how the depression, performing ability of IADL and muscular-skeletal pain are related to the subjective health index of the Aged, we have conducted an enquete through a direct interview with 693 persons over age sixty-five (65) in Daejon and in other adjacent areas, divided into three different residential types “The Aged living at home”, “The Aged living at welfare facilities” and “The Aged living alone”. We have studied all the data and information obtained through this enquete and have analyzed χ²-test, t-test, ANOVA, analysis of simple correlation, analysis of factor. by SPSS10.0/PC+. The results were as follows: Generally, the four (4) factors depression, IADL performing ability, muscular-skeletal pain and the subjective health index of the Aged, are a lot influenced by and related to their residential circumstance, their sex and their age. With regard to the depression of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 48.3 point which reflects comparatively the higher points and the female-Aged is more depressed. In analyzing depression of the Aged by their age, it appears that the Aged between eighty (80) to eight-four (84) years of age, gains 49.2 point which is the highest points and simultaneously we could realize that depression follows age, - the more the age gets, the more the depression is increased. In analyzing depression of the Aged by their residential type, it shows that “the Aged living alone” gains 50.9 point and is most depressed. With regard to the IADL performance of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 23.8 point, which shows the performance of the female-Aged is less independent. In addition, it was also found that the IADL performing ability is becoming less and less independent following their age increasing. In analyzing IADL performance by their residential type, it appears that “the Aged living at welfare facilities” gains the lowest 21.5 point and is least independent. We conclude that some assistances from others are required for the Aged living at welfare facilities in their performing IADL. With regard to the muscular-skeletal pain of the Aged by their sex, it was analyzed that, on an average, the female-Aged gains 3.0 point and the female-Aged suffers from this pain more severely. In analyzing this pain by their residential type, it was found that, on an average, the 3.0 point goes for “the Aged living alone”, which explains the Aged living alone is having the most serious pain. With regard to the subjective heath index of the all Aged participated in this research, the analysis indicates 8.8 point and this is considered as a general standard (7-10 point). In analyzing this index by their sex, the female-Aged gains 8.6 point only and it explains a lot of female-Aged consider they are not really healthy. In analyzing this index by their residential type, “the Aged living at welfare facilities” and “the Aged living alone” gain the comparatively lower point, -respectively 8.4 point for the Aged living at welfare facilities and 8.8 point for the Aged living alone. The Aged of these two residential types express they are obviously in a bad condition of health, which makes us think a lot. With regard to the factors affecting the subjective health index of the Aged, it was analyzed that this index can significantly be influenced by their depression, their pain, their age and by how much they are satisfied with their current living conditions, and also analyzed that the correlative relation certainly exists between the depression and pain, and the subjective health index, - that is, the more the depression and pain are serious, the lower the subjective health index indicates. As for the IADL, it appears that the IADL's relation with this index is not that significant and even not important.
