Silver is widely used for catalytic decomposition of hydrogen peroxide, but start-up at room temperature is difficult and cannot withstand at high temperature. In this paper, to overcome these short-comings, a dual catalytic bed which consists of a vaporizer catalyst and a high temperature catalyst was studied. Platinum was selected as the vaporizer catalyst and perovskite type catalyst was selected for the high temperature catalyst. Preliminary test demonstrated start-up capability with non-preheating at room temperature and good thermal stability at high temperature.

The purpose of this study is to analyze the planning concept and spatial characteristics of the multi-housing units in prize-wining works of design competition since 2007. Literature review and content analysis were used for this study and 199units over $59m^2$ were analyzed to review the planning concept, spatial composition and layout. The results of this study were as follows; 1)The planning concept of these units were divided into three aspects; that is, eco-friendly, rational and sustainable unit plan by means of functional, environmental-friendly and future-oriented aspects. 2)Most unit plans had 3LDK+2bath and 4Bay types including family room as a public space. This results shows that family-room and bathroom has recently become more important than number of rooms in multi-housing units planning. 2)In terms of the spatial composition of LDK and Master Bed room, LDK area become large, open type and master-zone were showed 'bed room+dress and powder room+bath' type. 3)The entrance has a intermediated space as a balcony or a former space and the privacy of LDK space was protected from the entrance. This study has a significant moaning on grasping current trend in Korean multi-housing and to provide Information for future direction on housing-unit design.

A ward is a place where the patients are living and staying for 80% of the all those days in the hospital. So the Ward's conditions are very important to them. We group a ward's conditions in two classes, one in the physical condition ; area, noise, temperature etc. and the others is the physical condition ; privacy, field. According to the analysis, the patients had beed under a mental stress and they did negative action, by the ward's environmental conditions. This study find influence of the ward's environmental conditions with violate each patients privacy using multi-bedroom's restroom. So we suggest that the ideal multi-bedroom's restroom, solve the they got the problems.

As changed population structure variously, population decrease is one of the important problem in present urbanization. It resulted decline of the medium-large size housings that increasing of 1-2 person household need the variety of small housing with housing type. This study was researched the Gold-Generation on theme by Gold Miss, Gold Mr. who preferring urban small housings that it analyzed survey of Gold generation who be wanted urban small housing by interior coordination elements. Data to be analyzed that first, Gold Mr. and Miss are preferred two bedroom applied by spatial structure coordination. Especially it is based on the separation between livingroom and bedroom with duplex type which is bathroom formed single unit type(shower/toilet/basin). In interior coordination of spatial elements, Gold Mr. considered the form of kitchen with huge ㄷ type instead of Gold Miss are preferred alpha room or alpha space to use powder room or dress room. Second, In Preference of interior coordination elements, Gold Mr. and Miss are preferred bed-clothes and curtains by fabrics, lighting are hanging and spot lighting, accessories are carpet with rug and porcelains.
