  • Rainwater harvesting systems (RWHS), one of measures for on site rainwater management, have been promoted by laws, regulations and guidelines and have been increased. However, more evaluation of economic feasibility on RWHS is still needed due to seasonal imbalance of rainfall and little experiences and analysis on design and operation of RWHS. In this study, we investigated tank capacity of RWHS to secure economic validity considering catchment area and water demand, which is affected by building scale. Moreover, sensitivity analysis was performed to examine the effect of design factors, cost items and increase rate of water service charge on economic feasibility. The BCR (benefit cost ratio) is proportional to the increase in tank capacity. It is increased steeply in small tank capacity due to the effect of cost and, since then, gently in middle and large tank capacity. In case of 0.05 in the rate of tank volume to catchment area and 0.005 in water demand to catchment area, BCR was over one from the tank capacity of 160 $m^{3}$ taking into account of private benefits and from the tank capacity of 100 $m^{3}$ taking into account of private and public benefits. Sensitivity analysis shows that increase of water demand can improve BCR values with little cost so that it is needed to extend application of rainwater use and select a proper range of design factor. Decrease of construction and maintenance cost reduced the tank volume to secure economic validity. Finally, increase rate of water service charge had considerable impact on economic feasibility.

  • According to shift of the political focus from agricultural productivity to social development, it has been increased importance of local leader in rural society. Especially rural women leader's role has been increased not only in agricultural business but also in social activity of locality. Although a lot of leadership study related to rural community development, it has been very scarcely study about leader's action in pattern or doing in style based on psychological scale. Therefore this a kind of pilot study on that. For this data, it was gathered from 24 female farmer leaders of a federation group in 2005. In this study, to define the action in pattern or doing in style of leader, it was adopted to Ozasz Yoshihisa's scale which is consisted of 40 items into 8 types. From analysis of female farmer leader's action in pattern or doing in style, most of them were belong to volunteer type, generalist type, farmer type. This menas most of them were head toward maintenance of the present status, keeping one's balance, adaptation oneself to new environment, or acceptance the logic of events, not trying to innovate. But it was not clear that any variable has a relation in the action in pattern or the doing in style, for definition of variables, it should be more detailed study.

  • Long-life housing means a housing which structural members (Support) such as columns and floor are maintained for a long period of time and the housing can be used for approximately 100 years by replacing components (Infill) such as walls and furniture. The government established "Certification standards of long-life housing construction" on December 24, 2014, requiring the long-life housing certification for construction of apartment houses for over 1,000 households. However, it is necessary to prepare an incentive measure which could be granted to construction related personnel and housing owners due to the effectiveness of such system and recognition that the initial construction cost of long-life housing is high. The purpose of this study is as follows. First, the reasons and necessity of long-life housing cost increase for each construction company, housing owner, infill component manufacturer and designer which are long-life housing related personnel are determined. The direction of incentive grant for supplying long-life housing based on the determined items is established. The result of this study is as follows. First, a special treatment which is higher than the alleviation of construction standards according to the previous ordinance is necessary for construction companies to secure the business feasibility. Also, incentives such as the provision of service space and wide balcony are necessary to improve the preference level of parceling out. Second, financial incentives such as financial support for housing purchase, reduction and exemption of tax (acquisition tax and registration tax), and support of maintenance cost are required for house owners. Third, it is essential to increase opportunities to participate in the market for infill component manufacturers by applying additional points for PQ. Fourth, it is needed to provide compensation for additional human resource and time at the time of designing to designers by preparing the long-life housing design cost standards.

  • This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

  • Introduction : In Korea, national attention to the workplace health promotion programs (HPP) for employees began in early 1990s. Governmental supports for the HPP and education programs have given to the employees. The purpose of this study is to find the performance degree of employees' health promoting lifestyle(HPL). Subjects and Methods : For this study, 615 employees who attended governmental educations were selected as research samples. The tool for measuring HPL used in this study was developed for Korean by In-Sook Park in 1995. It is composed of 4-point scaled 60 items and divided into 11 subcategories. The data were collected by self reporting questionnaires from June to December in 1997. Those data were analyzed percentile, mean, standard deviation, ANOVA, t-test with SAS program. Major findings are as follows; 1. The total mean score of the employees' HPL performance was 2.66. The average scores of 'harmonious relationships' category were the highest as 3.11, whereas the one of 'professional health maintenance' were the lowest as 2.02. The remains were 'sanitary life'(2.90), 'emotional support(2.85), 'regular diet'(2.84), 'self achievement'(2.78), 'healthy diet'(2.56), 'rest and sleep'(2.56), 'exercise and activity'(2.54), 'diet control'(2.53), 'self-control'(2.52). 2. The factors affecting HLP were category of industries and sex, age, marital status, education level, major, educational experience of health promotion, among personal characteristics. The employees of service industries, female, older age, married, nurse, educated for health promotion, graduated from junior college performed HLP more than the others. 3. The participation rates of employees for HPP were 12.4%, because of limited time and facilities and equipments. Recommendations; 1. The regulation for performing the health promotion programs in the industries is essential for activating industrial health promoting movement. 2. More governmental supports for educations and services for health promotion programs in the industries are needed. 3. For behavioral changes of the employees, the contents of educations have to consist of exercise and activity, rest and sleep, diet and smoking habits. 4. The evaluating studies for ready made health promotion programs in the industries are expected.

  • An IPA model was used to evaluate customer service encounters at a large food court; also the gaps between importance and performance from were also evaluated from both perspectives. The findings of this study will be applied in order to improve service quality at various large food service operations. A total of 298 customers from a large shopping mall food court completed the study questionnaire, asking them to evaluate the important and performance attributes of service. Seven underlying dimensions were identified and labeled by factor analysis: factor 1 was "safety": factor 2 "time": factor 3 "atmosphere": factor 4 "quality of food": factor 5 "menu attributes": factor 6 "comfort": and the last and seventh factor was "comprehension". As a result of IPA analysis the overall mean scores between the importance attributes and performance attributes showed significant differences by independent t-tests(p<0.001). Quadrant I was classified with unnecessary items including interior design, proper lighting, suitable chairs, and proper room temperature. In quadrant II thirteen variables showed high scores for both importance and performance, such as various menu choices, hygienic food, dishes, chairs, food court, kitchen, and employees; proper ventilation, employee kindness, waiting time to order, and received food; automatic system for ordering-serving. Quadrant III included eight variables identified as low priority, including appearance of food, nutrient content of food, proper portions, new menu, proper music, proper location of cashier, services for children and efficiency of movement. In quadrant IV six variables were included as areas to focus management's efforts, such as food taste, proper food temperature, use of safe food materials, maintenance of food quality, existence of preferred foods, and proper food prices. These results suggest that food court customers have interests that are distinct from restaurant customers and may need to be treated differently. It is anticipated that this data will be useful to the foodservice industry in order to segment customer characteristics by different dinning behaviors.

  • In recent years, the recipients of the services of the health centers in Korea have been shifted from individual sick persons to families as a unit. As a result, the home visiting care records which are all filled out manually, will be increased. Since there is virtually no increase in the number of community health nurses, the CHNs are required to work more efficiently. One of the ways to make the CHNs' work more efficient is to reduce recording time by using a computer. However, a computer system that can manage the families as a unit has not yet been developed. In response to this need, we developed a database system that can be utilized in home visiting care service. The family assessment data is collected. diagnosed. and evaluated according to the family diagnosis classification. The system for family diagnosis consists of seven areas. Those areas are family structure. maintenance of the family system, interaction and interchange. support. coping and adaptation, health management. and housing environment. The areas of the family diagnosis consists of 99 items in all. We expect the following from this system. First. the CHNs will be able to identify family problems more easily. Second. the community's health level can be confirmed by the statistics the system produces. Thirdly, the CHNs' nursing services will be cost effective via reduced recording time. Finally, the family problems of the sick individuals which have been neglected under the health system oriented on individual persons can be effectively managed.
