The purpose of this study is to provide a basic for a desirable bathroom plan of apartments. As a first step in this process, we analyzed the bathroom plans of the apartments(area: 10-69 pyung) constructed in 8 sections in Seoul from 1971 to 1995 where 65,801 households live. In this study, the numbers, location, size, and proportion of the bathroom and dressing room, and the direction of the bathroom door in apartments are examined. The major frindings are as follows; 1) We have found that the numbers of bathrooms to increase in more than 20s pyung apartment since 1990. 2) Except a master bathroom, the another one for the guest is located in enterance in more than 40s pyung apartment. 3) The door of the bathroom faces corridor in more than 40s pyung apartment. So, it is possible for them to lessen discomfortness when they coming in and out of the bathroom. 4) It was found that the size of bathroom were decreased in most cases. 5) They did not plan a dressing room in 10s pyung - 60s pyung and the size of dressing room was decreased in 60s pyung apartment.

In this paper, the all units of residential housing that is not legislated in facility development law are analyzed and foreign design criteria that is related to barrier-free unit housing is comparing to domestic. Through the comparison in front door, living room, bathroom, bedroom, and kitchen, this paper aims to suggest internal barrier-free design criteria. This paper is limited to internal housing which are front door, living room, bedroom, bathroom, and kitchen. Also, the objectives of facility development law are U.S, Japan, German, and in case of U.S, UFAS is established by ADA, in Japan, Heart Building law and detail standard drawing are used, in German, DIN is used. The objective of domestic case study is the latest residential housings that are built over 2003. The flow of study is as follows ; First, the internal items of residential housing are abstracted, and each item is checked in facility development law that is legislated in. Next, through comparison of domestic and foreign facility development law related to housing, common items are abstracted and detail standards are defined. Domestic residential housings are analyzed in those standards. Finally, the problems that is the result of analysis are analyzed and the barrier free design criteria is abstracted in unit housing. Also, more developed items and future study are suggested.

Lastly, the problem of filling occurs in the process of concealed joint of adjacent components and was seen in joints between the structure and an electrical or mechanical device. Therefore, the dry processing which replaces wet joint was seen in joints between the structure and a door, ones between the structure and a finishing materials, ones between a gypsum board and electrical device, and ones between a water pipe and a tile finishing. And a process of separating the area of jointed parts in order to eliminate the problem of overlap was seen in joints between a door and a finishing material and ones between a gypsum board on the ceiling and a light. Lastly, an analysis of a process of exposing concealed parts indicated that the problem of filling could be applied to joints between the structure and an electrical or mechanical device and ones between a finishing material and a mechanical device. This study sought out methods to apply Environment Friendly Multi Housing Remodeling that allow easy remodeling as part of environment- preserving policies. It also contains basic data useful to implement long-life houses in the future by presenting a comprehensive design standard for them

Laboratory equipment will continue to be developed and created as long as experiments continue. Up until now, the designs have been focused on the functional role; successfully process the study purpose. However, nowadays, the requirements of providing emotional satisfaction of the design, has increased. Even so, the users are normally limited by specific groups and investments on these designs have been neglected due to small annual production by the small market. Through this study, we have conducted an emotional evaluation on Temperature and Humidity Chamber's (TH Chamber) exterior shape. First of all, we extracted emotional words and placed them in categories that represent these emotions and conducted an emotional evaluation on four typical TH chamber models. They were selected based on its door lock type and control box type. The result showed that the 'fixed type' of control box and the 'handle type' of door lock were most favorable by the users, satisfying the five representative emotions; 'Attractiveness', 'Classiness', 'Comfortableness', 'Pleasant' and 'Satisfaction in Usability'. Particularly, all 4 emotional words in the 'Satisfaction in Usability' category recorded over 3.65. This indicates that Satisfaction in Usability is relatively an important category when expressing laboratory equipment. The result of this research is expected to be used as a basic data to find a way of right approach in laboratory equipment design.

This paper presents the reliability estimation of door hinge for home appliances, which consists of bushing and shaft. The predominant failure mechanism of bushing made of polyoxymethylene(POM) is brittle fracture due to decrease of strength caused by voids existing, and that of shaft made of acrylonitrile-butadiene-styrene(ABS) is creep due to plastic deformation caused by excessive temperature and lowering of glass transition temperature by absorbed moisture. Since the brittle fracture of bushing is overstress failure mechanism, the load-strength interference model is used to estimate the failure rate of it along with failure analysis. By the way, the creep of shaft is wearout failure mechanism, and an accelerated life test is then planned and implemented to estimate its lifetime. Through the technical review about failure mechanism, temperature and humidity are selected as accelerating variables. Assuming Weibull lifetime distribution and Eyring model, the life-stress relationship and acceleration factor, $B_{10}$ life and its lower bound with $90\%$ confidence at worst case use condition are estimated by analyzing the accelerated life test data.
