This study was carried out in order to understand the plan, design, constructing and actual condition of management of modernized horticultural facilities in Kyungpook Province which had been constructed from 1992 to 1995 funded by Government support. The aim of this study is to provide reference data for success of the forth project. It was performed by making up a question about driving of project and management condition of equipment after constructing. The results obtained from this study are as follows: 1. 73.5% of facilities horticulture farmhouse recognized that the prospect of greenhouse is bright, but 92.5% of the farmhouse also recognised that they need technical consultation on protected horticulture farming. Therefore, technical educations would must be enhanced about foundation of greenhouse and cultivation technique. 2. The holding times of explanatory meetings, cause of understanding to farmhouse, were one or two times in greenhouse construction, and 62.5% of the farmhouse expressed the insufficiency at the explanation and educational data. For this reason, it was judged that the construction contract had been delayed more than 5 months in 49.3% of the farmhouse after the decision of project budget. 3. In constructing after a contract, the rates of construction delay is 53.4% and defect occurrence is 41.1%. The biggest reasons of construction delay was insufficiency of worker and materials supply. Each percentage is 29.1%. And the reason of defect occurrence is badness of machinery equipment(62.9% ). 4. In management of greenhouse, a pipe-constructed plastic film greenhouse changes plastic film every one and three years because of sticking dust on plastic film. It was needed to about in cleaning technique of coverings. Because that used 3-5 years only half of the expected life span. 5. The order of broken rating in the subsidiary equipment is like this lollop ventilator (42.8%), a general control system(33.3%) especially, in the case of a general control system, the rate of all family can control is 52.7%. so, it is time to develop easy control equipment which every one could use as soon as possible. 6. When choose heat generator as decide capacity, the most priority is the mount of heat generator the percent is 45.5% heat generator and as decide model, the private purchase's percent is 77.3%. It is higher than a public bidding heat generator the percent is 22.7% heat generator when it compare with a public bidding. In the case of $CO_2$ generator, using rate is only 19.0%. The using rate is very low, so it needs education how to use depends on the way of the subsidiary equipment. 7. In the case of seedlings, it is asked to use factory-processed seedling effectively. because it's difficult to get security of labors(58.8%), hoped crops (55.9%) access same crops(29.4%) much more and changing of crops depends on market situation. that is the main reason the lack of knowhow.

The purpose of this study is to develop the playground environment model for child care center by analyzing user needs of playground environment. To systemize the playground environment design factors and guidelines, we reviewed the previous research, actual measurement and observation were used as the research methodology. And to recognize the needs of users, the survey and picture survey was conducted to the staffs and children. The scope of survey included child care centers in Seoul and Daejeon, ultimately selecting 12 places in Seoul and 13 places in Daejeon. In terms of the survey period, actual measurement was conducted from June of 2006 to February of 2007, survey and picture survey was conducted from August to September of 2006. For analysis, we used SPSS 10.0 to check the frequency and percentage, as well as to perform cluster analysis. The findings of research can be summarized as below: 1. In playground environment, we observed the area of play ground and ground cover, the independence of play area, play equipment, and the composition of play area. The result of observation showed that while playground area varied widely, ground cover, play equipment, and the composition of play area turned out to be identical, regardless of the playground's area. Therefore, in order to classify various playground environments, we categorized them into 5 types, using the number of children and the area of play ground as a category. Type A had large facilities and small playground area. Type B had small sized facilities and large playground area. Type C had medium sized facilities and small playground area. Type D had medium sized facilities but large playground area. Type E had large sized facilities and large playground area. 2. On the other hand, staffs wanted a tunnel, playhouse, comprehensive play equipment, and a maze to be installed as play facilities, and there were requests for adventure play area and carpenter play area. The picture survey to children showed that they wanted equipments that can provide more thrill, adventure and challenge to them than the ones they see now. Therefore, existing child care center play environments must change from the monotonous and identical environments to the ones that can provide diversities, challenges, and adventures. In the contexts of 5 playground types suggested by this research, type B and D, E where the area of playground were larger than the legally required, should include various play areas and install appropriate play equipments and facilities. Type A and C where the area were small, should provide multipurpose play area to attract the various play behaviors of children.

Recently, many performing arts facilities are under construction to accommodate people's various interest in cultural experiences. However, due to Korea's lack of know-how in such constructions and an absence of proper regulations on design planning, each designer designs and constructs the facilities differently, so several problems are occurring in the process of construction, such as high production cost for stage sets, high labor cost, low efficiency of stage work, and complicated work process. This resulted in low quality production of performance. This study is conducted to address the need for a systematic study on stage floor, and to propose an efficient way of regulating stage work in existing performing arts facilitiesand new facilities to be built. By a comparative analysis of performing arts facilities in Korea, and by analyzing stage floors of the facilities, this research suggests minimum modules as well as an appropriate unit of modules based on the minimum modules; and provides basic data on stage floors, which can be used for remodeling existing facilities orfor planning new cultural facilities. Also, this study suggests various ways of utilizing performing arts facilities in Korea.

Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of dimensional and detailed standards have hardly made. Therefore we intends to examine the status of bathroom planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into five representative elderly housing facilities in Korea. We visited each two units out of the outstanding 5 facilities and surveyed the total ten bathrooms. Then we analyzed the space planning of them and the state of bathroom commodities, and measured the bathroom equipment. In addition, we collected questionnaires about satisfaction, preference, and problems from the residents. As a result, most of the bathrooms had powder rooms and were furnished with bathtubs(4) and shower stalls(6). One or more grab bar and emergency calling system were provided but the heights of the handles were different from each bathroom. The floor material of bathroom should be installed with no-slippery material.

Recently, the small-scale local governments of japan are enlarging and enriching the service of health, medical and welfare facilities for the elderly . Intensive arrangement of the three types of facilities is one of the effective ways especially for the small-scale local governments. The service network between facilities benefits by the intensive arrangement. Benefits include the network of the medical service, the share of care information, the share of space and equipment. It can be a notable feature in the intensive arrangement that the elderly were taken from welfare facilities (especially dayscare center) to hospital of high movement frequency quickly. Instead of EV path as possible, It is desirable to stand close between facilities of high movement frequency. For large area, the heavy snow made low daycare ratio. Therefore, it is desirable to construct a branch office at a long distance.
