Along with the increasing number of disabled people, number of handicapped people who spends most of their time indoors increase. Their disabilities constrain them in social activities and bind them to indoors. But living environment built for normal people are many cases inevitably inconvenient for disabled people. People realizes that housing renovation is necessary, however problems such as financial difficulties must be solved in advance. House renovations, to create comfortable and independent living conditions for disabled people, various thesis and documents were analyzed, along with survey through questionnaire. Results are as following. (1) House renovation is necessary, due to the increasing number of disabled people and inconvenience of former house form. (2) Integrated or specialized house renovation manual is required to satisfy the different need derived from extent and type of disabilities. (3) Central and local government's policy for continued support is necessary. (4) House renovation plan for homeless disabled people is necessary. (5) Separate research on the size of space, type of space, efficiency is necessary. (6) Separate house renovation plan considering the people who lives with disabled people is required. (7) Disabilities are not personal but societal problem. This paper is to uncover all the problems in the house renovation for disabled people. It will be used to develop house renovation manual in the future. Therefore, this paper does not deal with the actual house renovation plans.

N/A In this study, electron microscopy, Fractography and Jic test have been used to investigate the fracture behaviour in the scope of aging temperature which 7075 Al-alloy can have high strength. Conclusions obtained on this study are as followed. 1) When the 7075 Al-alloy was aged for 24hrs at 120℃, it`s mechanical properties was excellent but fracture toughness decrement resulted from intergranular fracture was emerged. 2) The state of aged for 24hrs at 100℃, had the highest fracture toughess. 3) We could infer that intergranular fracture occurred because preferrential precpitated precipitates in the grain boundary growed in the form of colinear along the grain boundary.
