The purpose of my study is to provide some information on clothing for the handicapped with special needs. So I have designed clothes for the handicapped to provide some solutions for their clothing problems. These clothing designs for crutch and wheelchair users were based on solutions proposed by many researchers. The number of handicapped has been increasing gradually for years, especially the physically handicapped. Although they make use of many instruments for ease of movements and other physical conditions, most of the handicapped generally use crutches and wheelchairs. So I designed clothing for the crutch and wheelchair users. In order to ease problems in dressing and undressing, when using the crutch and wheelchair, various physical attributes of clothing should be considered: (1) Selection of fabric, (2) construction and location of the opening, (3) type and location of fastenings, and (4) design of garments for comfort and ease of movement. Clothing should also be able to satisfy psychological needs related to attractive appearance. My designs have proposed seven items of clothing. These include a cape-coat, over-blouse, one-piece dress and an pants for the crutch users. Also, a shirts, pants, and wheelchair wrap for wheelchair users will be displayed.

The Fuel cell Rubber tired Train (FRT), which is now getting the attention as the next generation vehicle with its environment-friendliness, is the transportation for smooth connections of city traffic. It is the revival of the surface-car system with its revaluation of the function and technological development. Accordingly, fixed time operation and high speed driving became possible. FRT is operated together with other vehicles on the regular drive way. While this vehicle can solve the problem of traffic congestion in the urban area, it also can be cost-effective when it is compared to the cost of subway construction. It is also designed to minimize the underground or elevated traffic lane, to introduce the new construction technology, to reduce a term of works, and to cut down the operation cost by unmanned automatic driving system. Furthermore, it is considered as the alternative measure of other transportation due to its potential for the ecological way of speed improvement and the accessability to the disabled, elderly and children by developing the vehicle with folding steps or by building the high boarding platforms. In this research, I concentrated on the user oriented interior design of the FRT to make it passenger-friendly and safe in order to maximize the utilization of the vehicle so that all users including wheelchaired, user with baby carriage, elderly and children can conveniently use this vehicle.

Existing user research methods are subject to a variety of research conditions such as the amount and variety of data collected and the expertise of the facilitator of a group research session. In this study, we propose a new user research methodology using an 'Issue-Network' system, which is developed based on the theory and methods of social network analysis. The Issue-Network is designed to define problem spaces from the issues raised by users in a group research session in a form of an interactive network graph. The system helps to break out of ordinary perspectives of looking into problem spaces by enabling an alternative and more creative way to connect issues in the network. In this study, we took a case study of generating the Issue-Network on behalf of the problems raised by users in various driving-related situations. We were able to draw three navigation usage scenarios that cover relatively important problem spaces: safety and being ready for the unexpected, smart navigation and notifications, making use of the spare time. In the future, the Issue-Network system is expected to be used as a tool to identify problems and derive solutions in group research sessions involving a large number of users.
