Current seismic design guidelines in Japan are diverse in the seismic ground strain estimates, because the concepts on a horizontally propagating wave model are not consistent in various seismic design guidelines including gas, water and other underground structures. The purpose of this study is (a) to derive the analytical methods to estimate the ground strains for incident seismic waves, (b) to develop a statistical estimation technique of the ground strains, and finally (c) to compare the theoretical estimation with the observed data which was measured at 441 sites in the 1999 Chi-Chi Earthquake in Taiwan.

The study was intended to suggest the design alternatives and guidelines of village community center as a common living space for the elderly in rural area. First, two design alternatives were derived from the previous research which examined the conditions and old persons' needs of village community center. Then, the design guidelines were proposed on the basis of the previous research and the elderly's evaluation for those two alternatives. The subjects were 85 old residents who were more than 60 years old and lived in rural area in Gyungnam. The interview was carried out using a questionnaire, models, and isometrics of two alternatives. The subjects evaluated positively both of two alternatives. The design guidelines of village community center were derived as follows: Both of two alternatives can be used as a model of village community center. The dining and living space in the center should be opened and large. Both of indoor and outdoor toilet should be arranged in village community center. Also, each toilet for man and woman should be separated.

This study has been conducted focusing on the analysis of the turn-key proposal for Gimpo-Han River New City. The study expected that it would come up with design trends and introduction properties of each plan for the eco-friendly development of an apartment house. The concept of environment-friendly design was thought in four parts: 'Land use and transportation,' 'Ecological environment', 'Energy resource and environmental impact' and analysis factors of each part were chosen by specific items from the prospective researches and guidelines that already given on the projects. In conclusion, a proper development of the environmental-friendly apartment house will not be achieved unless the designers try to overcome their prejudice against eco-friendly planning elements applications. Along with the designers' attempt, it is also necessary to review the evaluation articles of the certification system for the existing environmental-friendly structures as well as to compensate and establish detailed evaluation standards. As the problems are being worked on, an integrated, effective evaluation standard for the eco-friendly planning elements will be determined. This way, an environmental-friendly residential development with a better quality will be eventually realized.

Objective: The aim of this study is to introduce an operator console design review system suitable for designing and evaluating consoles based on human factor guidelines for a digitalized main control room in an advanced nuclear power plant which has a requirement for anthropometric data usage. Background: The system interface of the main control room in a nuclear power plant has been getting digitalized and consists of various consoles with many information displays. Console operators often face human-computer interactive problems due to inappropriate console design stemming from the perceptual constraints of anthropometric data usage. Method: Computational models with a process of visual perception and variables of anthropometric data are used for designing and evaluating operator consoles suitable for human system interface guidelines, which are used in an advanced nuclear power plant. Results: From the computational model and simulation application, console dimensions and a designing test module, which would be used for designing suitable consoles with safety concerns in a nuclear power plant, have been introduced. Conclusion: This case study may influence employing a suitable design concept with various anthropometric data in many areas with safety concerns and may show a feasible solution to designing and evaluating the safety console dimensions. Application: The results of this study may be used for designing a control room with the human factors requiring a safe working environment.

This study is a preliminary study to develop design guidelines on shared spaces of apartment for healthy housing. It was tried to set the basic direction of the guideline development by comparing and analyzing related literatures based on the previously identified evaluation indicators of healthy housing of apartment. The major findings were as followings: 1) based on the research conducted before, the characters of shared spaces for healthy housing were classified as physical, mental and social dimensions. 2) According to the comparison and analysis of relevant standards and guidelines, focuses were mostly on the physical dimension, particularly on the human traffic lines of the convenience attributes. Other focuses were on the attractiveness of the apartment complex of the vitality attribute under the mental dimension, and community facilities of the residential stability attributes under the social dimension. Therefore, it was identified that it is required to take complementary measure regarding mental and social dimensions, and design concrete steps to include different attributes of each dimension, in order to develop comprehensive guidelines for shared space.

Since the scaffold is composed of modular members, the total height of multi-story scaffolds does not often meet with the headroom of construction buildings. At this time, other supporting members need to be set up on the top of scaffolds. However, the mechanical behaviors of the combined system of scaffolds and other supporting members have seldom been discussed. This study explores the stability of the combined system of scaffolds and shores. The loading tests conducted in the laboratory show that the critical load of the combined system of two-story scaffolds and wooden shores is about half that of the three-story scaffold system with the same height. In the failure of both the "scaffold system" and the "combined system of scaffolds and shores' after loading, the deformation mainly occurs in the in-plane direction of the scaffold. The outdoor loading test shows that no failure occurs on any members when the combined system fails. Instead, the whole system buckles and then collapses. In addition, the top formwork of the combined system can achieve the effect of lateral support reinforcement with small lateral support forces in the outdoor loading test. This study proposes the preliminary design guidelines for the scaffolding structural design.

The demographic profile of the households will shift towards the 'older elderly'. There are need upgrading existing housing and new housing in aspect of floor plan, accessories, facilities and so on. The government should prepare the policy and standards of housing design for the aged and disabled in order to improving the residents' housing conditions. The purpose of this study is to compare Korean to foreign guidelines related to residential design for the elderly and disabled and find out the characteristics of our standards. It was accomplished by literature research. The results were as follows. There is disagreements between domestic standards over the clear door opening, the clear hallways and handrails at entrance. And the foreign standards are based on their wheelchair size, ours are founded on it's size which specified only maximum overall dimensions. So ours are seem to be lack of accuracy. Our standard of stairs is in details in comparison with other space components. But ours don't go into details than foreign ones over length of hand-rails, riser etc. And for recommendations denoting minimum and maximum height of various component, it should be preceded the specific survey on limits of reaching ability for the elderly and disabled.

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.
