The purpose of this study is to develop a business model that efficiently converts diesel power generation systems to renewable energy microgrids (MG) in large-scale islands. Most of the previous studies on the conversion of renewable energy MG in islands had limitations dealing with efficiency from the perspective of suppliers. However, the microgrid has the characteristic of getting benefits through the interaction between the consumer and the supplier. In addition, the efficient MG business model from the perspective of new institutional economics is a structure in which consumers and suppliers jointly participate. Therefore, this study assumed that the MG business model in which the supplier's MG and the consumer's community solar participated would benefit all participants, and verified the assumptions using domestic island data. In terms of supplier investment, the cost of power supply (LCOE) of assumed model was calculated to be 14.0% lower than that of the diesel model and 3.7% lower than that of the supplier-only MG model. From the perspective of consumer investment, electricity bills are expected to be reduced by more than 200,000 won per household per year through self-generation of solar power. Social benefits are expected to reduce external environmental costs. The CO₂ emissions of the assumed model were calculated to be 39.5% lower than the diesel model and 1.5% lower than the supplier-only MG model. Therefore, the MG business model with consumer participation proposed in this study is expected to be an efficient alternative to renewable energy MG conversion in domestic islands, and is meaningful as an energy plan that improves the benefits of local residents.

The purpose of this study is to suggest improvement directions and analysis of assistive technology service linkage on public benefits in local assistive technology center. The service steps and the main program parts of public benefits linkage in local assistive technology center was identified, and the present status of associated repair works and contact suppliers of assistive technology device in local community was investigated. The result showed the most common level of associated status to provide information of assistive technology devices in public benefits. All the centers provided repair service, and it was typically performed to light maintenance. The centers offered with associated professional repair service supplier for high maintenance service. The connection with assistive technology device supplier appeared a lot of regional difference. Henceforth, the centers will be required to distribute more various assistive technology devices, it is necessary upgrading the quality of information and interaction with the public benefits supporting organizations through its expansion, and it is need to ensure based on policy through the analysis of the effectiveness about linkage.

This study was undertaken to provide basic data for revitalizing the school meal support centers and improving school meals, by analyzing the purchase conditions and satisfaction of food according to an adoption of a school meal service support center. Comparing the purchasing efficiency, convenience to purchase, and higher overall satisfaction was achieved when a school meal service support center was adopted by the local government, as compared to non-adopted school meal service support centers. Therefore, it is considered that the adaption of a school meal service support center is urgently required by non-adoption local governments. Moreover, the stability of food material supplies was also higher in the adopted rather than the non-adopted centers. Satisfaction with the quality of food ingredients was also found to be significantly higher in the adopted centers. These results indicate that if the local government adopts and introduces the school meal support center, inconsistencies observed in the return and exchange processes experienced by the non-adopted centers can be resolved, and food quality satisfaction can be improved. We, therefore, propose the necessity to implement a system for determining reasonable pricing by establishing systematic cooperation among schools, manufacturing entities (suppliers), and the School Meal Service Support Center.

The purpose of this study was to investigate school dietitians' satisfaction with and needs for School Meal Service Support Centers. A web-based on-line survey was conducted with 1,102 nutrition teachers or school dietitians using four School Meal Service Support Centers during the summer of 2011. The data from 578 respondents (52.5%), consisting of 165 (44.4%), 334 (53.4%), 41 (67.2%), and 38 (86.4%) dietitians using Seoul, Gyeonggi, Suncheon and Gyeongju centers, respectively, were analyzed. The main reason for using the centers was subsidies from local governments. The dietitians using the metropolitan centers, which were Seoul and Gyeonggi centers, tended to buy agricultural products through the centers only, and those using local centers, which were Suncehon and Gyeongju centers, bought those products from the private suppliers as well as from the centers. The dietitians' overall level of satisfaction with the centers was not high showing 3.3 out of 5 points; it was significantly associated with the operating system and services of the centers such as system efficiency, delivery accuracy, communication, and information provision rather than the agricultural products provided by the centers. The dietitians preferred joint operation of the centers by local governments and producers' groups. They wanted School Meal Service Support Centers to be evaluated every year. It was suggested that efforts should be made to improve the operation system and service of School Meal Service Support Centers for improving dietitians' satisfaction with the centers. In addition, an evaluation system for School Meal Service Support Centers should be implemented soon based on school dietitians' needs.

The use of local product foods and fresh-cut products, the dietitian's recognition, the required items and the quality for school foodservice was investigated to increase the consumption of high-quality agricultural products. Data from 578 elementary schools, 228 middle schools and 116 high schools were collected by school foodservice personnels in each regional Education Administration in Gyeong-gi province. The first criteria of buying food materials was reliability/safety for all school foodservice. The second criteria were the origin of the product and freshness/ripeness for elementary and middle schools and high school, respectively. The most important consideration for selecting a supplier was the quality of the material. The appearance/status of the food was the first factor for buying food materials. The origin and the seasonality were very important for buying farm products. Dietitians in Gyeong-gi province recognized the local products, and used them weekly. The advantages of using local products were the quick supply, freshness and safety. On the other hand, the disadvantages were the lack of information and the uncertainty of supply. Sixty eight percent of the subjects had experienced the high-quality agricultural products in school meals, but the frequency was low. The main reasons for not servicing high-quality agricultural products were the high cost and the lack of trust on the quality. Among fresh-cut products, seasonings and root vegetables were purchased most frequently, but leaf vegetables was 5.7% only. The purchase of fresh-cut products was not frequent, but usually satisfied. The advantages of fresh-cut products were the reduced workload and waste, but the reason for not using them were poor hygiene and the high price. The diverse supply system and the promotion of the local product foods would be necessary since the most food materials were purchased through suppliers. In addition, the problems related to the high cost and distrust should be resolved to expand the consumption of the high-quality agricultural products and the fresh-cut vegetables. The institutions for certifying the quality should be needed to increase the confidence of these products.

Attracting advanced foreign enterprises into the less-developed regions has gained increasing importance as a regional development strategy in Korea. This study critically examines the foreign-direct investment-led regional development strategy of Wales, United Kingdom. Despite a high FDI inflow in manufacturing, the Welsh regional economy has suffered from specialization in low-skilled assembly with limited R&D activities, insufficient linkage with local domestic suppliers, and violent fluctuation in local employment in response to changes within the global business environment. This tendency shows that the foreign-invested companies have neither locally embedded themselves enough nor created the external agglomeration economies in the region. At the same time, the Welsh local government's excessive dependence on financial incentives packages to induce multinationals, rather than effort to create regional innovative capacity, has resulted in a sizable fiscal loss, an abused local planning process, and subordination of the local government's major administrative decision-making on foreign investors. The Welsh FDI case suggests that an effective FDI attraction policy should include inter-regional cooperation and coordination in the inward investment attraction procedure, a comprehensive land use planning process, and state-level concrete governance on FDI.

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jeon. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'difficulty of monitoring'. To assess the factor as a obstacle we used Likert's scale; 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-don't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except ‘lack of dietician's understanding about HACCP System(2.86$\pm$0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) ‘Deficiency of hygiene facilities(4.41$\pm$0.76), ‘lack of teachers' cooperation(4.23$\pm$0.77)', ‘inadequacy of the kitchen lay-out(4.19$\pm$0.95)' and ‘lack of training and educating program for employees(3.97$\pm$0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.

This paper studied the present condition of social welfare activities of Living Condition Improving Committee of Kimpo City in order to activate the social welfare services of women agricultural organizations. The main results are as follows; First, the general characteristics of the respondents in this study are forty or fifty years of age with above high school education with main income source of agriculture and middle class women living in agricultural communities more than 10 years. Second, considering the present and future planned activities of the Living Condition Improving Committee of Kimpo City this study finds that there is high expectation of helping poor people and joining voluntary services. Third, the members of the Living Condition Improving Committee of Kimpo City have actively participated in the local welfare service programs however, there is significant difference among people according to the age, living standard and joining period. Fourth, out of social welfare activities managed by the Living Condition Improving Committee of Kimpo City the welfare service activities for old people and local community are most active and the participants in the welfare service activities for women and the youngsters are small. Thus, according to this study the Living Condition Improving Committee of Kimpo City should consider the following three points in order to activate the social welfare service activities; First, as the members are expecting to expand the individual activities and to enhance the private improvement, the social welfare service activities should meet with the demands to improve self satisfaction of the participants. Second, new programs should be developed after reviewing the current programs in order to meet with the need of the members. Third, as the committee has not established a network system with government administrative organizations and relating institutions, and as its activities are concentrated in particular areas the committee should establish a new system to provide more efficient services in line with the cooperation with public organization and welfare resource suppliers.

The number of public libraries in Korea has been increasing. However, the focus was on quantitative growth, while it did not have much interests in whether its growth trend are have deviations by region, and if that is a fact, what factors caused such a disparity. For this reason, this study analyzes spatial distribution of public libraries in Korea and its affecting factors of regional gap. As a result, public libraries are constantly distributing in the metropolitan area and the distribution of public libraries showed deviations by region. The results of analysis regarding the determinants of public libraries distribution, rate of population growth, the number of businesses and financial independence rate are found to have a positive effect but local taxes per capita are not. Especially economic power of region and financial ability of a local government are key factors of regional disparity. It shows empirically that the supply of public libraries has been determined by the convenience of suppliers.
