Urban style row-rise houses for rent have been supplied to the center of city from the 1950's first half The amount of stock is about 450,000 houses and occupies about 40％ in the private rented house. As for the structure, the 60％ of them is wooden-structure and the rest is non-wooden. Stocks of 57.5％ of the wooden-structure and 86％ of the non-wooden were built after 1981 years. It was 1981 years that the new earthquake-resistant standard was carried out, the improvement of stocks built before 1981 is necessary because those don't satisfy the present standard. To investigate the renovation possibility of urban style row-rise houses for rent, actual situation of two-story apartment at 2,4, and 5 Chome Taito-Ku in Tokyo was surveyed from July to November 2001. The number of building analyzed is 227 ridges among 234 ridges of the surveyed two-story building. 90％ of building analyzed is wooden structure. 1) The site of 88％ building surveyed is close to a road less than 4m width. It becomes the existing non-conformed building in the building construction act. It is impossible to make a renovation such as rebuilding, extension and remodeling because it requires the set back when renovating this type of non-conformed building, 2) The building built before 1981 is almost wooden-structure, and occupies 37％ of the building surveyed, and doesn't satisfy the present earthquake-resistant standard. An improvement of them is needed because the decrepitude of building proceeds. 3) 50％ of openings and 40％ of windows of the building surveyed doesn't use noncombustible materials. Though it becomes the existing non-conformed building, it can satisfy the present standard by replacing openings with noncombustible materials.

Recently, childhood obesity is increasing in Korea mainly due to westernized dietary pattern. The purpose of this study is to investigate diet pattern(habit and behavior), nutritional knowledge and taste favor in normal and obese children. We carried out anthropometries and self questionaire about life style among the 5th-grader in elementary school(88 boys, 102 girls) in Seoul. The results are as follows : Physical conditions are boys’average hight and weight 142.0cm, 37.5kg ; and girls’143.7cm, 35.6kg. BMI are normal group 38.7% and abnormal group 61.3%(obese 24.2% underweight 16.1% overweight 14.0% very underweight 7.0%) A great part of obese children live in apartment house(79.5% of obese children in southern Seoul; 60.2% in northern Seoul). Obese parents have obese children. Diet behavior, diet pattern, food habit and food preferance of children are similar to their parents, especially their mothers. Preferance in taste of children follows in order of hot, sweet and mild. Especially obese children favor sweet taste more than others. The 61% of them are interested in weight control. Their nutritional knowledges are poor(4.9/10). They like more westernized food(hamberger) than korean food(In-jul-me).

I recognized necessity of the space planning to three-generation dwelling because of preservation of wholesome society sense of values of the younger generation indicated often to the point at issue by the change to nuclear family of present and by way to hand down thought of respect for the aged which is our traditional public morals. I wish to present basic data for storage space planning that resident's request and consciousness are reflected in such background. I investigated records in general concept, which is utilization pattern of storage space to achieve the function of these culture intermediation. The object of research is three-generation dwelling, such as 3L-K and 3L-DK as national residences that appear most generally in chongju city. The method of research was question investigation method to write utilization actual conditions and requirement of storage space directly. So I proposed suitable planning to resident's life style analyzing frequency, percentage and average distribution. When supply apartment house hereafter, it should be reflected wide selection by resident's characteristic and needed systematic storage space planning in consideration of user mainly. Also continuous and diversified researches that can improve quality of residence are required.

The purpose of this study was to analyze the state of Goryoin housing in Uzbekistan and Korea. Using ethnographic methodologies, it was examined that 20 Goryoin households in Korea in relation to their usage of housing space firstly and also tried 20 Goryoin households in Uzbekistan with the same method. The following conclusion were established; 1). The majority of households in both areas preferred separated kitchen and living room areas. 2). Most households in both areas had a washing machine in bathroom and they regarded bathtub and the drain hole of the bathroom as very necessary. They all preferred separate bathroom and toilet areas in order to allow simultaneous use. 3). Their preferred seating style was chairs on sleeping and eating especially but they treated large family and guest without chairs in both areas. 4). All of them were took their shoes off and wore slippers at home usually and also had a preference for designated shoes space at the entrance to the house. 5) All of households in Uzbekistan and half of them in Korea had a carpet or mat in the bedroom or living room, both for keeping warm and aesthetic reasons. 6). The heating system of apartment in Uzbekistan was radiator and most of private houses had a modified Ondol with radiator but their preferred heating system was modified Ondol in both areas. 7).

The purpose of this study is to form a calculation formula of the mean skin temperature on the human body in a heated room by the use of floor heating system. Korean traditional floor heating system is a long way from being defunct. The floor heating systems based on hot water have been coming into wide use mainly in the apartment house. However, it is considered that the design process and evaluation method for the floor heating systems in the standpoint of human being are not established so far. In the floor heating systems, air temperature as well as floor temperature should be considered as physical factors which affect the sensation of human body. Furthermore, extremely few studies have been performed on the sitting with legs crossed posture sedentary which is the typical dwelling life style of residents from the ancient times in Korea, while a large number of studies on the influence of the floor heating systems on the human body in standing and sitting on a chair sedentary have been carried out. Especially, it is essential to elucidate how mean skin temperature on the human body is affected by thermal conduction in the contact area between the sitting with legs crossed posture sedentary human body and floor including thermal radiation due to the combination of air temperature and floor temperature, but the studies dealt with such issues have hardly been performed. Based on the above statements, the influence of the environment condition due to the combination of air temperature and floor temperature is discussed in the present investigation through theoretical of mean skin temperature on the human body in the floor heating systems.

The purpose of this study is to investigate the trends and patterns of various kind of water uses in a household by metering in Korea. Water use components are classified by toilet, washbowl, bathing, laundry, kitchen, miscellaneous. Flow meters are installed in 140 household selected by sampling in all around Korea. The data are gathered by web-based data collection system from the year 2002 to 2006, considering pre-investigated data such as occupation, revenue, family members, housing types, age, floor area, water saving devices, education, miscellaneous. Reliable data are selected by upper fence method for each observed water use component and statistical characteristics are estimated for each residential type to determine liter per capita per day. Estimated domestic per capita day show an indoor water use with the range from 150 lpcd to 169 lpcd for each housing type as the order of high rise apartment, multi-house, and single house. As the order of consuming amount among water use components, it is investigated that toilet (38.5 lpcd) is the first, and the second is laundry water (30.8 lpcd), the third is kitchen (28.4 lpcd), the fourth is bathtub (24.7 lpcd), the next is washbowl (15.4 lpcd). The results are compared with water uses in U.K. and U.S. As life style has been changed into western style, pattern of water use in Korea is tend to be similar with the U.S. water use pattern. Compared with the surveying results by Bradley, on 1985. Thirty liter of total use increased with the advancement of economic level, and a little change of water use pattern can be found. Especially, toilet water take almost half part of total water use and laundry water shows lowest as 11% in surveying at the year of 1985. But, this study shows that 39 liter, 28% of toilet water, has been decreased by the spread of saving devices and campaign. It is supposed that the spread large sized laundry machine make by-hand laundry has been decreased and water use increased. Unit water amount of each end-use in household can be applied to design factor for water and wastewater facilities, and it play a role as information in establishing water demand forecasting and conservation policy.
