A green area plan is getting attention as a way to solve the recent urban problems such as the rise of environment problems. To correspond to this change, there were dramatic amendments for the green area related laws. These amendments are appraised as the epochal turning point for the green area policies. This study is to introduce the main contents of amended urban green area law and urban park law in Japan, to compare with the Korean green area related laws, and to summarize the special features of both countries' green policies and the comments about the Korean green area policy structures. As a result, this amendment of Japan established the unified green area policy structure supporting the green area policies of municipal governments and is inducing living environment improvement by securing green area in the center of city, support, and the participation of residents. On the other hands, this amendment of Korea is a lack of the systemization of green area policy and the phased establishments of green area plan in spite of the scope of whole city because of absence of the unified high level plan.

Although Korea joined OECD in 1996, there has still seen much unbalance in medical care and welfare standard between urban and rural area. The unbalance of medical demand between urban and rural area deepened low utilization of rural hospitals. So it caused many hospital's failure and conversion in rural area. Many rural hospitals are in difficulty managing business because of low medical demand along with the shortage of medical manpower, medical equipment and facilities. The objectives of this study were to reveal the cause of low utilization of hospitals in rural area, and to increase utilization of those hospitals. In this study the improvement methods of rural hospital's utilization were presented by examining were placed in difficult management condition, in respect of hospital's management conditions, manpower input, patient medical treatment record, financial record, and actual output. The causes of rural hospital's low utilization were as follows; 1) changes in number and structure of population 2) rural people's preference for large hospitals and hospitals which located in urban area 3) rural hospitals lacking in hospital management skill. Consequently rural hospital's operation condition got more and more deteriorated. To raise rural hospital's utilization, method for social policy, method for health policy, and intrinsic method of hospitals were presented in turn. For rural residents to utilize medical service conveniently, it is necessary for rural hospitals operated normally. So government must insist that rural hospitals solve the problems which come out from their internal management problems. And also these rural hospitals should be supported and nurtured by the government until their management is operated normally.

This study examines and analyzes residential environment and consciousness of downtown residents in Naju city and its results are as follows. Naju's population or urban population were decreased by half for 25 years, but area of residential regions was increased twice. It indicates that major parts of increased residence area are occupied by housing site development area. Uses of downtown buildings are for residential building mostly, but commercial building is less than 1/3 and story of buildings is mostly the first floor. So downtown area in Naju has residential function mostly and family composition is over sixties in more than half of population and regional aging is remarkable because household over majority of the population has no family under twenties. Downtown areas showed detached house and their own house in 2/3 of population and residents over majority of population have lived in current house over 20 years and had strong settlement. But housing site area is less than 40 pyeong at 3/2 of population and 2/3 of population have not parking lot. Most of population have dissatisfaction with their residential environment and for solving their dissatisfaction, improvement of poor residential environment, road extension and construction of parking lot are needed most. Most of residents consider that improvement of residential environment or economic level is normal or developed a little compared to five years ago, but when such a dissatisfaction is solved, they continue to live in their area.

The purpose of this study is to propose a framework to analyse the educational effects and outcome of the boarding middle school established following the merger and abolition of small schools in rural area. According to the decrease in birth rate and reduction of population in rural area, primary schools have brought about many problems for decrease of number of student, and environment of education have became deteriorated. Accordingly, primary schools be required improvement, and it should be altered placement of schools because it change number of student, distance and time of attending school, and formation of school zone are changed by alternating of human and physical environment. Merger and abolition of primary school is inevitable for change of placement standard to primary school and qualitative improvement of environment of education in rural area. This study suggests 1)educational effects and outcome, 2)changes and benefits of student's living conditions, 3)social effects to local community, and 4)economical efficiency analysis as a new framework to evaluate the validity of establishing a school. It sets up a hypothesis that the students, parents and community satisfy the boarding school in rural area, a school record be improved and the abolition of schools have little effect on community. Finally, it emphasizes that in order to success the policy of the merger of small schools and the boarding middle school, it be attributed to the social-cultural environment based on local residents and community and required provision of a variety of utilization plans reflecting local specifics and guarantee of local residents' participation and selection.

In this study, we analyzed how the revenue water ratio(RWR) is affected by changes in conditions of the water supply area, such as the ratio of aging pipes, maintenance conditions, and revenue water. As a result of analyzing the impact of pipe aging and maintenance conditions on the RWR, it was confirmed that the RWR could be decreased if the pipe replacement project to improve the aging pipe ratio was not carried out and proper maintenance costs were not secured. It was also confirmed that an increase in the revenue water could be operated to facilitate the achievement of the project's target RWR. In contrast, a decrease in the revenue water due to a population reduction could affect the failure of the target RWR. In addition to analyzing the causes of variation in the RWR, the calculation of estimated project costs was considered by using leakage reduction instead of RWR from recent RWR improvement project cost data. From this analysis, it was reviewed whether the project costs planned to achieve the target RWR of the RWR improvement project in A city were appropriate. In conclusion, the RWR could be affected by variations in the ratio of aging pipes, maintenance conditions, and revenue water, and it was reasonable to consider not only the construction input but also the input related to RWR improvement, such as leakage reduction, when calculating the project cost.

A numerical simulation was performed to investigate the internal flow characteristics in gas turbine nozzle by the variation of flow area of the nozzle. In general the area of turbine nozzle is chosen by the most substantial factor on performance improvement of turbine at the first stage. In the performances test through CFD analysis for three types of nozzle with conventional, enlarged and reduced area, reduced one with effective flow area (EFA) was the most efficient. That is the minimum effective value within EFA limit defined by the manual of technical order had a good performance. It is useful to avoid the low power problem in the test of performance after maintenance and overhaul of turbine engine.
