The purpose of this study is to analyze space composition and size of the Master Zone in the apartment unit plan. For this, we analyzed 435 samples by searching web-sites of the 5 main construction companies. The major results of this study are as follows. 1) Master Zone is organized 4 spaces such as main room, bathroom and make-up & dress room. Six types of Master Zone are classified with the composition of 4 spaces. 2) The size of the Master Zone is increased in proportion to the square meter. But the range of the ratio is small range of fluctuation as 20%${\sim}$30%. 3)The size and ratio of the each spaces of the Master Zone are analyzed. The size of bedroom is increased but the ratio is decreased. The size of bathroom is increased but the ratio is regular as 4%${\sim}$5%. The size of make-up and dressing room is generally increased but the range of the size and ratio is the most extensive. Through this analysis and research, this study would be provied the basic data for actual housing planning and to contribute to future trends of apartment houses.

This study focused on evaluating the reliability of code formulas such as those of the current Korean Building Code(KBC 1988). UBC 1997, NBCC 1995. and BSLJ 1994 for estimating the fundamental period of RC apartment buildings with shear-wall dominant systems, representative of typical residential buildings in Korea. For this purpose, full-scale measurements were carried out on fifty RC apartment buildings, and these results were compared to those obtained by code formulas and also by dynamic analysis. Although these code formulas are based on the measured periods of buildings during various earthquakes and building period varies with the amplitude of structural deflection or strain level, ambient surveys should provide an effective tool for experimentally verifying the design period to the completed building. This comparison shows that comparatively large errors are likely to occure when the code formula of KBC 1988 is used, and all the other code formulas are not sufficient to estimate the fundamental period of apartment buildings with shear-wall dominant systems. An improved formula is proposed by regression analysis on the basis of the measured period data. The proposal is for the servicebility stress level, but it can also be applied for seismic code in the regions of low seismicity similar to Korea.

Instead of installing new communication wiring to each house in the apartment house building. the power distribution network. which is already installed in the building. can be use as communication medium. In a safty management, by adoption of power line communication system, at remote we can monitor safty related sensors such as fire, gas leakage, burglar intrusion and emergency call which are located at each house. From this viewpoint, we developed security monitoring system for apartment house building using power lines. Security monitoring system consists of Power Line Communication-Sub Controller (PLC-SC). Power Line Communication-Main Controller (PLC-MC) and Management System (MS). Between a PLC-MC and a PLC-SC, the transmission rate is 1200 bps in power lines and modulation technique is frequency shirt keying (FSK). In between a PLC-MC and a MS, the transmission rate is 1200 bps in communication line (RS-485). As a result of this research. transmission loss is 0.1dB per meter of intrabuilding distribution network. Transmission can be reach in 250 meters. So it is enough to communicate for security monitoring system in apartment house building.

Actually, prediction formula of road traffic noise for EIA(Environmental Impact Assessment) has been used that proposed by National Institute of Environmental Research in 1999. The prediction formula, however, was calculated predicted noise level according to noise level producing on first floor, then needs to correct noise level at each floor in the case of apartment building. The investigation was carried out to calculate the correction coefficient for commonly using in EIA of large scaled apartment development areas. The noised level at each floor were measured from August 2001 to March 2002 at 31 investigation points of large scaled apartment development area in national wide. Measured data were divided and treated with 4 types as 3th floor, 5th floor, 7th floor and 10th floor and then the correction coefficients of each floor were calculated using by correlation formula according to each floor.

During last 4 decades of industrial development, apartment has been rapidly disseminated throughout the nation. Its main progress, however, only appeared in quantity, not in quality. To promote housing industry in more way and to enhance peoples' life quality through the better housing environment, housing plan should be based on living items including furniture, appliances and etc. Not enough research has been done to find out living items for better house plan development and furniture design. Among living items, furniture reflects both directly and indirectly people's lifestyle and way of living. This study attempted to find out the pattern of furniture possession which people own in their bedrooms. An in depth questionnaire survey of 600 households was carried during the year 2000. A variety of patterns were found which indicated diverse living conditions within a very similar uniform multifamily apartment complex. The result of this study will be helpful to understand the living conditions in a more systematic way and to generate new concept for both residential unit plan and furniture design.

This study was intended to suggest the design alternatives of housing units which were developed on the basis of POE. The POE of the New Apartment Complex in Gimhae was carried out and on the basis of the results of this POE, the design alternatives of housing units were developed. The subjects were 372 housewives who live in the apartment houses sized 60m2 to 85m2 in Gimhae. They answered about the living characteristics related to house, the degree of saisfaction with their housing unit plans, and the needs for housing unit plan. The major problems in current housing unit were the lack of storage space and the small size of living room and children's bedrooms. Many residents wanted to live in the housing unit which have three bedrooms and some of them wanted two bedrooms. Also, they wanted to enlarge living room and instead of that, to reduce master bedroom. In addition to these, the residents had diverse housing needs. On the basis of these results, housing alternatives which are flexible and optionable were suggested.
