Finite element method and Taguchi method were used to reduce the floor impact vibration of the reinforced concrete slab in the apartment buildings. At first, experimental results show that sound peak components to influence the rating of floor impact sound insulation were coincident with natural frequencies of the reinforced concrete slab, and there is a high linear relation between floor impact vibration and sound. The tables of orthogonal arrays were used for finite element analysis with 5 factors related to slab shape parameters and its results were analyzed by statistical method. The most effective factor to reduce the floor impact vibration was the length of living/kitchen room and the floor impact vibration was predicted by 30% reduction in the acceleration peak by the optimal design values of the factors.

The purpose of this study is to present the design guidelines of residential unit for the elderly by investigating their needs and preferences. The results of this study will be utilized to develop the alternative elderly housing which is appropriate for the Korean culture. To perform an empirical analysis, the existing data collected in 2000 for the study of silver industry In Ulsan were used. The subjects were 292 elderly aged 65 and over living in Ulsan. Statistics employed for the analysis were frequencies, percentage, and Chi-squared test with cross-tabulations. About 70% of the elderly respondents preferred more than 49.5$m^2$(15-pyung) for the size of residential unit and about 50% of them wanted to have bedroom, bathroom, kitchen, and living room In the unit. Most elderly (72%) did not prefer to select interior finishes for their units by themselves. Surprisingly, the elderly did not want to bring their own furniture when relocating to the elderly housing, which was somewhat different result from previous studies. There were significant differences between preferred unit size and level of education, income, and living with or without spouse. Also, income and health status were the characteristics of elderly which made differences in preferred space composition.

The fast growth of the elderly population and nuclear families have been creating substantial needs for residential facilities of aged people in Korea. In this study, reviews on housing preference and physical constraints have been performed based on previous researches. In this study, the results of the analyses propose developmental strategies for the elderly housing in Korea as follows: 1)Housing preference and other psychological trends of Korean elderly are rooted in changeable condition of the emotion and lack of knowledge. Therefore, the housing preference of the Korean elderly should not be considered a fixed reflection ; rather, it should be regarded as a continuously adjusted trends according to later experience and emotional status after residing in the elderly care facilities. 2)Design of elderly housing should be guided within two principles of easy access and high usability. The principles also require maximazation of social interactions among frail elderly residents on age-segregated structure. 3) The experiment among 201 frail elderly shows that each shower stall should accommodate 5-by-5 feet square for wheelchair u-turn, and 48 inch height for kitchen topsink. Finally, the experiment shows that ramp slope of the ederly housing should be within 1/16 and 1/20.

Most existing residential environment of disabled people has made them exposed to the risk of safety accidents, and therefore hinders their independent living. In this regard, the importance of desirable residential environment has emerged. Some preceding studies have addressed the characteristics of disabled people's residential environment plan; however, the information on what environmental benefits are offered through such characteristics is insufficient. This study aims to analyze the housing design guidelines for disabled people in respect of the benefit of disabled people who are actual users. In this study, essential design guidelines for disabled people verified through expert workshop panel was analyzed based on user benefit theory. According to the study results, the total guidelines have the most characteristics supporting behavioral facilitation, and mainly consist of physiological maintenance characteristics related to disabled people's health and safety. Also, it is founded that environmental affordance essentially required depending on each spatial function was different. The ratio of physiological maintenance item is high in access route, unlike living room, kitchen and bed room where behavioral facilitation is especially emphasized. These findings can be utilized as basic data for customized residential environment plan to realize residential welfare for disabled people.

The purpose of this study was to the characteristics of the interior space composition for luxurious apartments and the trend of interior design. Surveying visits were made to 30 model houses for which individual apartments of 8 million Won or more per pyeong (about 3.30 square meters) were on sale from December 1999 through November 2000 in Seoul and suburb area, pundang. The major finding were summarized as follows; (1) The characteristics of the planes indicated that the living-room separation type accounted for the majority, which was not generally different from common apartments. The master zone divided several room. The main room which conventionally played the roles of the family gathering space and the second room shared by family members, was designed exclusively for husband and wife. Distinctively separated from the other spaces, it was to be used for personalized space, together with bathroom for the couple, dressing room, or study. Attempts were made for the high-class apartments to get away from the common uniformed apartments, such as the yard-type balcony or the second entrance in consideration of the moving path. (2) The characteristics of the interior designs showed that the detailed attention was paid to every composing element for the emphasis of the high quality image. The factors determining the quality were finishing materials, kitchen furniture, hygienic ceramics, electrical appliances water supply equipment, or functional storage closet.

This study was conducted to examine housing preferences among single-person households and to propose guidelines for housing design choices for single people. One hundred and sixty responses to the questionnaire developed by this researcher were analyzed utilizing frequencies, percentages, and t-tests. There were significant differences between single households and non-single households in various aspects of housing preferences. Differences were found in the desired type and size of housing, needed amount of space, and the importance of space itself. Single persons wanted to live in a small apartment, about 83.45$m^2$ (25.29 pyung) size. They consider the bathroom and the master bedroom more important than the living room and kitchen. They prefer to have specifically function-oriented rooms such as shower, home office, computer room, exercise room, or leisure space. Single persons consider information-technological facilities within an apartment very important. They would like to adopt automatic and electronic technology in the house, such as optical communication network, automatic air-cleaning system, and internet TV. Housing preferences differ significantly according to socio-demographic variables such as gender and age. I propose in this study a small-sized, information-, high-tech- and leisure-oriented design that corresponds with the actual housing preferences of the single-person households.

The school food service system has been an important national policy in Korea. To find out the reference data of the school food service system, we surveyed four primary schools, one middle school, and one food service center in Nara, Japan. The results are as follows; 1. The school food service was carried out in 99.4% of primary school children and in 82.5% of middle school students. 2. The central commissary school food service system was utilized at 49.0% of primary schools and 68.5% of middle schools. 3. The expense of the system is supported partially by the student's parents and partially by the government, of which the support rate was noticed by the law of school food service. 4. The dietary content of school food service was laid down by 'The rule of the operation basis of school food service'. The menu was chosen by the 7 kinds of stepwise meetings. 5. The teachers emphasized on the food etiquette, the appreciation to the food and the personal relationship during meal, as well as on the nutritional balance. 6. We found other problems in Japanese food service system, such as the sanitary problems, the problems of the new tableware, and whether the central kitchen had less advantage than the individual school kitchen. We can conclude that the school food service system is becoming the essential part in school education, and hope to design not only economical but also educational system in Korea, with the consideration of Japanese system.

This study was intended to suggest that new small-sized apartment houses should be designed and provided on the base of the concept of universal design. This is based on the diversity of each resident, that is, resident of not as a family, but as an individual. On the background of this, this study evaluated the small-sized apartment house in aspects of universal design. The walk-through and the residents' evaluation were carried out by using 60 items related to the principles of universal design. The 18 pyung apartment complex and housing unit in Jangyou new town area was evaluated. Also, 100 residents living in that apartment housing unit were asked to evaluate these 60 items by using 5 point Likert scale. The walk-through with measuring and taking pictures was carried out by researchers. In general, the apartment house was not met the fundamental elements of universal design. Thus, it was not appropriate for the disabled or the elderly to live in. Specially, the door width of bathroom and kitchen balcony was too narrow to pass through. Also, the floor of entrance and bathroom was not flat, so that the wheelchair user cannot enter by alone. The residents evaluated negatively many items related to design, such as shape, color, and material. Therefore, in order to provide the living environments for diverse residents such as the elderly, or the disabled to live together, the new small-sized apartment houses should be designed on the base of the principles of universal design.
