This study aims to clarify the architectural characteristics of three houses of Choseon Exhibition. Exposition/exhibitions were thought to be a model for the world. It shows the real status of the development, and thinking with visions at that times; therefore, exhibited house models would be a good source for what to be considered for the ideal houses of that times. Through the study, we could find out as belows. 1. The houses exhibited conserved the sitting-on-floor living style, otherwise the most proposals for house improvement suggested a chair-and-table style because of its hygienic quality and integration of the life at home and at work(school, too). 2. The spacial scheme for-family prior over for-guest was emphasized, but models at the exhibition were structured with Japanese traditional spacial program, such as Jashiki(座敷), Kyakunoma(客の間) or Tsuginoma(次の間), which were all Tatami-floored. 3. Through this exhibition, it is clarified that the architectural society in colonial Korea also tried to improve the modern housings, not only direct reception of the developed proposals. These houses was planned with the acceptance of the locality, such like Ondol, a floor heating facility which the Japanese engineer improve the efficiency. 4. Also these exhibited houses became a start to recognize a house as a product, and spurred on commercialization. As the result, we could find out that these exhibited houses accepted the modern housing proposals selectively, and that even if the exhibitions shows the advance in usual these houses were planned with the very conservative notions.

To find out abnormal electrical conditions, periodic inspections for residential houses are being performed every 3 years. According to data from KESCO, the number of uninspected houses is rising as the number of empty houses during normal working hours is rising by dramatic increase in the number of nuclear families and double income families. As a result, potential hazards are increased by them. In this paper, a model of a national electric safety network is presented. In the model, functions for ubiquitous environments were partially realized.

In the present study, feasibility investigation on the solar assisted hot water supply system for apartment houses was carried out by the review of service facility and heat load pattern. Also analysis and experiment of the small sized system model were performed. This hybrid system are consists of solar collector, heat storage tank, controller, and gas boiler using LPG as a secondary heat source. The analytical results showed a good agreement with experimental data. We found that this hybrid system could reduce the energy cost by 30% for hot water compared to typical boiler system in the apartment houses. Also we showed that this model could be used for the energy and economic analysis of the hybrid system.

A steady-state analysis and a simple dynamic model as simplified methods are developed, and results of energy consumption loads are compared with results obtained using computer to evaluate the analytical solution. Before obtaining simplified model a mathematical model is formulated for the effect of wall mass on the thermal performance of four different houses having various wall construction. This analytical study was motivated by the experimental work of Burch et al. An analytical solution of one-dimensional, linear, partial differential equation for wall temperature profiles and room air temperatures is obtained using the Laplace transform method. Typical Meteorological Year data are processed to yield hourly average monthly values. This study is conducted using weather data from four different locations in the United States: Albuquerque, New mexico; Miami, Florida; Santa Maria, California; and Washington D.C. for both winter and summer conditions. The steady state analysis that does not include the effect of thermal mass can provide an accurate estimate of energy consumption in most cases except for houses #2 and #4 in mild weather areas. This result shows that there is an effect of mass on the thermal performance of heavily constructed house in mild weather conditions. The simple dynamic model is applicable for high cycling rates and accurate values of inside wall temperature and ambient air temperature.

Remodeling of apartment houses has been increasing recently and residents have chosen to extend the balcony along with the legalization of balcony extension in apartment houses. Balcony extension provides residents more space, however, it has been investigated that balcony extension increases construction cost, heating and cooling cost and decreases sound insulation performance. Therefore, this study focuses on developing a decision making index for residents in remodeling required apartment houses. The suggested methodology involves surveying actual residents, survey analysis by AHP and decision model development using logistic regression analysis.

This study was conducted in seven metropolitan cities in south korea containing Seoul and Busan etc and used DevC++ language program in the process to get datas of the distance ratio between apartment houses by the length of time accepting sunshine during the day time. Basically by inputting information such as a certain date, longitude, latitude etc, it was possible to get outputs of the length of shadow. This study obtained the data from the model experiment and computer programs which analysis of the sunshine environment. As mentioned above, by analysing relations between sunshine-ralated laws in each cities and those influential factors, it is possible to suggest the fundamental data of distance ratio between apartment houses when designing a new building with more optimized way.

The vulnerability of roofing components of contemporary houses built in cyclonic regions of Australia is assessed for increasing wind speeds. The wind loads and the component strengths are treated as random variables with their probability distributions derived from available data, testing, structural analysis and experience. Design details including types of structural components of houses are obtained from surveying houses and analyzing engineering drawings. Wind load statistics on different areas of the roof are obtained by wind tunnel model studies and compared with Australian/New Zealand Standard, AS/NZS 1170.2. Reliability methods are used for calculating the vulnerability of roofing components independently over the roof. Cladding and batten fixings near the windward gable edge are found to experience larger negative pressures than prescribed in AS/NZS 1170.2, and are most vulnerable to failure.

최근 미분양 주택의 발생은 글로벌 금융위기와 내수경기 침체로 본격화되었으며, 주택보급률이 100%를 넘는 현 상황에서는 향후에도 언제든지 미분양 주택 적체가 심화될 수 있다. 정부는 이러한 미분양 주택 적체를 해결하기 위하여 여러 대책들을 수립 시행해 왔으며, IMF 외환위기 이후 부동산 금융시장의 발전을 배경으로 미분양 주택 유동화 대책이 시행되게 되었다. 또한, 2008년 이후 급격히 증가한 준공 후 미분양 주택은 단기간에 해결하기가 쉽지 않으며, 이로 인한 건설사의 유동성 위기를 해결하기 위해서는 미분양 주택을 유동화시킴으로써 자본시장으로부터의 자금 유입을 원활하게 하는 것이 중요하다. 따라서 본 연구에서는 정부의 미분양 주택 유동화 대책 중 최근 몇 년간 가장 문제가 되어온 중대형의 준공 후 미분양 주택을 해결할 수 있는 기업구조조정 리츠(CR-REITs)를 활용한 정책의 실효성을 시스템 다이내믹스를 이용하여 분석하고 개선방안을 제시하고자 한다.

The purpose of this paper was developing a development density control model for urban growth management, using system dynamics modeling. The density control model was developed to see how urban growth, transition, and decay occur depending on the interaction among population, houses, industry structure, land and urban infrastructure such as road, water supply, and sewage treatment facilities. Suggesting adequate level of development density control using the model was another purpose of this paper. The model was applied to An'yang city to estimate the maximum number of population, industry structures, houses, and cars that can be adequately sustained with the current An'yang city's infrastructur capacity. The computer simulation results shows that the city is overpopulated by some 90,000 people. To reduce the population to the adequate level that the current urban infrastructure can sustain, the current city regulation on floor area ratio are needed to be strengthened at least 20 to 35%.

Since aging has become one of most hot and serious issues in the whole global world, universal design as a strategic concept to enable the elderly age in place has received much attention and its importance is getting recognized. Japan has undergone the Aging phenomenon much earlier than Korea and other countries. During that time, through much trials and errors, it accumulated the wisdoms and techniques to precede aging friendly environment and products. Therefore current Japan house is a comprehensive setting which embraces lots of universal design features that has a valuable implication for Korean development that faces fast aging future. The purpose of this study was to delineate characteristics of universal design features appeared in Japanese Model houses. One site of housing park in the city where various model houses of representative housing construction companies was selected as a cluster area for data collecting. Data were collected mainly through field survey at the housing park of Tokyo during November, 2006, and additional data were collected through website and company information of relevant company. Universal design features were extracted for 17 houses of the housing park and sorted and analyzed according to the analysis frame. The frame were made using 2 major clusters; space area, and 8 universal design principle. Results showed a range of universal design feature and its detail universal design principle satisfied. The 8 principle currently developed became to house realistic practical examples and theory became proved its impractical power. The academic, educational and industrial implication were documented.
