This study was carried out to illuminate the flora of vascular plants of islands at Chungnam. This study was conducted from March to November, 2010. Based on the voucher, vascular plants of in investigated islands were 105 families 326 genera 454 species 4 subspecies 45 varieties 9 forms, totally 512 taxa. Korean endemic plants were 6 species such as Aster koraiensis, Salix koriyanagi, Indigofera koreana, Hemerocallis taeanensis, Hepatica insularis, Philadelphus schrenckii, rare and endangered plants of designated by Korea Forest Service were 4 taxa, such as Magnolia kobus (planted), Koelreuteria paniculata, Berchemia racemosa var. magna, Glehnia littoralis respectively. Phytogeographical special plants were totally 69 taxa, which were grade I of 50 taxa, grade II of 1 axon, grade III of 11 taxa, grade IV of 4 taxa, and grade V of 3 taxa. 14 southern plants and 4 northern plant by criterion from climate change study were found in this area. Naturalized plants were 17 families 46 taxa, that was 9.1% of total vascular plants in this area. Even naturalized plants has not influence on the islands vegetation. However, regular passenger ferry between islands and increasing of visiter will be affecting vegetation.

최근 계통연계가 도서산간지역의 전력문제 해결방안으로 마이크로그리드가 해법으로 제시되고 있다. 신재생에너지 및 디젤발전으로 구성되는 마이크로그리드는 신재생자원의 간헐적인 출력 때문에 적정규모를 선정하는데 어려움이 있다. 본 논문에서는 신재생 에너지의 간헐적인 출력을 고려하여 HOMER프로그램을 이용하여 적정 규모를 선정하고 감도 분석을 통하여 최적점을 설계하고 부하를 변경하였을 때 적절한 규모를 산정해본다.

This work investigated the social, cultural, and economical impacts of the services that S Children's Library provides to local community and its residents. In this study I analyzed the user statistics by using Korean Library Automation System III, practiced a comparative analysis with other libraries over circulation efficiency, and reviewed the user's evaluation through user survey. The achievement of this study is to find out the value of S Children's Library by verifying the service status of S Children's Library based on the analyzed data, assessing the role and meaning of the children's library within the community, and measuring the economical contribution through user evaluation.

The purpose of this study is to understand and analyse the community information services in Korean public libraries. Regarding this matter, this study first extensively analysed terms related to community information services and clearly defined the meaning of community information services. Second, this study investigated the current status of community information services in the public library. Finally, this study suggested the directions of community information services. In this study, literature studies and case studies were conducted, and the case to be discussed is online service of regional central libraries in Korea.

A pre-feasibility test is done for renewable energy hybrid power systems at off~grid islands in which the current power supply is provided only by diesel generation. We apply Homer (Hybrid Optimization Model for Electric Renewables) which was developed by the National Renewable Energy Laboratory (NREL) for the analysis to identify the cost-minimizing combination of power generating facilities for the given load profiles. Chuja-Do, Geomun-Do and Youngsan-Do have been selected for our analysis considering the wind resources data of the Korea Institute of Energy Research (KIER). Information on wind speed, solar radiation and temperature is also used for the analysis. System component cost information from overseas market has been used due to the lack of domestic information. Site specific Load profile for electricity demand for those islands are reconstructed based on the partial survey results obtained form other sources. The LCOE of the least cost hybrid power systems for Chuja-Do, Geomun-Do and Youngsan-Do are $0.278/kWh, $0.234/kWh and $0.353/kWh, respectively Considering the fact that diesel generation is being subsidized at the price of $0.300/kWh by the government, first 2 cases are economically feasible for the introduction of renewable energy hybrid systems to those islands. But the third case of Youngsan-Do does not meet the criteria. The basic differences of these pre-feasibility test results are from the differences of the site specific renewable energy conditions, especially wind resources. In summary, promoting hybrid systems in the off-grid remote island should be based on the economic feasibility test results. Not all the off-grid islands are feasible for introducing this renewable energy hybrid system.

The local bookstore direct loan service for users' requests in public libraries, which was launched in Gyeonggi Province, is a creative new service that has led to the revitalization of the local economy through the rise in sales of local bookstores and high user satisfaction. However, it is a service in which positive and negative reactions coexist as negative opinions are presented on the deterioration of the quality of public library books due to overlapping needs for desired books by users. Therefore, several ways of improving for local bookstore loan service in public libraries through a survey of public libraries, local bookstores, and users were suggested in this study. The local bookstore direct loan service for users' requests, which is a creative cooperation plan between public libraries and local bookstores, needs to constantly improve its services by increasing book purchase cost, organizing a steering committee for continuous communication and collecting plans through research on the book purchase cost. Also, it is necessary to improve its services by enacting regulations expanding reading culture services expanding the number of healthy users and fostering various local bookstores.

This study aimed to provide a fundamental basis for the development and promotion of a Korea windchill temperature index model in the field of human biometeorology. For this, a sensitivity model currently being used by KMA (Korea Meteorological Administration) was analyzed. The results of the analysis showed that the Korean peninsula could be divided into the urban area, the coastal/island area, the inland area, and the mountain area. The average temperature was highest in the coastal/island area, while it was lowest in the mountain regions. The lowest temperature in the urban and coastal/island areas was 20 degrees below zero and that in the inland and mountain regions were 30 degrees below zero. As for wind speed, both average and maximum wind speed were highest in the coastal/island area. The distribution of temperature and wind speed in winter was similar to that of the entire period. The results of the JAG/Tl and Missenard model sensitivity showed that temperature tends to have more influence on sensitivity than any other factors. In sub-zero temperature, however, the influence of wind speed tends to increase.
