  • It has been recognized that a policy for supplying solar house and hot water production systems utilizing solar energy needs to be driven to save civilian comsuming energy or to develop alternative energy. However, the economic feasibility study of solar energy systems must be carried out before their practical use. The purpose of this study is to furnish information for supplying policy and enlightening users with the economic feasibility study of solar house and hot water production systems. Decision support systems are established to carry out economic analysis on solar systems more accurately. Therefore, computer simulation is carried out to analyze the performance of solar systems and also economic feasibility study by trial and error method is carried out. Fuel cost and additional cost for solar systems are estimated employing present worth concept and economic analysis has been conducted using the break-even point analysis method and life-cycle cost analysis method.

  • The bookstart program for infants and toddlers is still in experimental progress. From this qualitative research that contains the both administration and utilization of the bookstart program at the Cheonan public library, some necessities for improvement were found to be the more effective program. The administration staffs of program consist of the supporting team and the instructional team. This program gives the meaningful experience to staffs such as the satisfaction as supporters of caring infants and toddlers, extension of social participation, and developing professionalism. The characteristic (purpose) of bookstart program for infants and toddlers could be categorized as three: offering a place to plays with other infants and toddlers, opportunities to exchange practical information, and chances to have educational support. To be more effective program, the difficulties and administrative problems of the program should be solved.

  • Health promotion has more comprehensive approaches in recent years. Nevertheless we accept the concept of health promotion differently, we are agree on that community is the most important field in health promotion which includes population at the aspect of health policy, individual skill and, environment. And there are a number of different approaches to health promotion. In them, 'population approaches' and 'high -risk group approaches' has the most different characteristics. 'Population approaches' is equally important or more important than 'individual approaches' for maintaining and promoting population health. Almost part of this article contents is the summary of the guideline and population strategy of health promotion in Korea, 1999 - 2005. Community based health promotion program should be reinforced, integrated, comprehensive, collaborative through efficiently utilizing community resources. Recent new orientation of community health program is integrated health program, we can find this orientation at Ottawa charter 1986. Comprehensive approaches with the determinant factors for health are essential task. Physical activity is a key health determinant. The population-health approach suggests that educating people about physical activity is not enough. Individual behavior changes are important too, but need to be balanced with strategies for environmental change. Population strategy with physical activity for health promotion should be developed through improving social and physical supportive environment, linking and integrating community resources between public and private sectors in national, regional and local level. Continuous public education and social marketing should be provided through collaborating with community physical activity organization, facilities, work-places and school for increasing concern of all the people of community about physical activity. Governments, agencies and citizens should held and participate to building movement. And the strategy that various 'active for life' program should be developed, delivered, maintained and reinforced continuously. Basically, adequate and sufficient financing, developing human resources, policies and legislation would be provided and supported fully too. At last, research development and knowledge exchange are required domestically and internationally. In Korea, we had classified the category of strategic priority of physical activity programs by environmental support, life-course approach, high-risk group approach and disease group approach for physical activity program based on community health center. Community based core programs for physical activity that includes infrastructure building and establishment of supporting environment, community campaign, health promotion education and public service announcement, physical activity programs for elderly and obesity, exercise prescription program.

  • The purpose of this study is to verify the applicability of concept mapping in the process of planning social welfare program based on community network. Concept mapping is a kind of decision-making method that structuralized complex ideas and presented visually. Already, concept mapping is widely utilized in counseling, nursing and public health area to plan and evaluation their program and service. For recent, effectiveness of concept mapping has been reported. Concept mapping is a effective decision-making method that they recognize outcome gap between service provider and client, reach the outcome's consensus in counseling and nursing, medical area. In this study, we conceptualized 3rd year outcomes of Community Impact Project that was supported from Busan Chest using concept mapping. This CI project intervenes children and youth who lives in Buk-gu, Busan. Concept mapping has six stages-preparation, collecting ideas, structuring statements, representing statement, interpreting the results of the analysis, applying the results. We followed these steps. The participants were working at social welfare organizations, total 11 persons. We obtained 60 statements and analyzed using multidimensional scaling. we collected 5 clusters, cluster 1 'awareness and attitude change of children and youth', cluster 2 'social system change of children and youth', cluster 3 'friendly community formation', cluster 4 'community people change', cluster 5 'service provider change'. As a result, among total 5 clusters formed, 'awareness and attitude change of children and youth' came to the strongest outcomes. When concept mapping was applied to the program planning, the consensus of the opinion came easily in the decision-making process, and the participants were empowered. In addition, clear conceptualization on each element of the program planning was made.

  • This study aimed to identify the effects of mothers' variables and present children's variables on subsequent childbirth plan and to explore predictors of subsequent childbirth plan for non-employed and employed mothers. The subjects were 1,635 mothers participating in the Panel Study on Korean Children from 2008 to 2010 and having no subsequent children until 2010 after giving birth to children in 2008. The data were analyzed with descriptive statistics, t test, ${\chi}^2$ test, and decision tree analysis. The main results of this study were as follows. Firstly, mothers' child-rearing stresses, child value, marital satisfaction, social support, present children's birth order and sex influenced mothers' subsequent childbirth plans, whereas mothers' average family income per month did not. Secondly, in the case of non-employed mothers, their present children's birth order and sex, and mothers' child value predicted their subsequent childbirth plan. Specifically, mothers whose present children's birth order and sex was first and female had the highest possibilities of subsequent childbirth plan, followed by mothers whose present children's birth order and sex was first and male, and child value was higher. Thirdly, in the case of employed mothers, their present children's birth order and mothers' marital satisfaction predicted their subsequent childbirth plan. Specifically, mothers whose present children' birth order was first and marital satisfaction was higher had the highest possibilities of subsequent childbirth plan. Finally, the study suggested the role of Home Economics Education in raising the rate of subsequent childbirth.
