  • 북한은 전력부족난과 전기품질의 저하로 인하여 주요 생산기업에 지장을 주고 있으며, 노후 발전소의 성능저하도 함께 진행되고 있는 것으로 추정된다. 이에 대한 적절한 대책이 없는 한 그 상황은 더욱 악화될 전망이다. 한반도 에너지 개발기구(KEDO)가 추진하고 있는 경수로 원자력 발전기가 6~7년 후에 준공된다고 해도 이처럼 불안정한 전력계통에 병입되어 원활한 운전이 가능할런지 기대하기 곤란하다. 이러한 실정에서 \circled1 전력부족으로 주파수가 저하될 때 우선 순위가 낮은 부하를 제한하는 자동 부하제한 방식을 포함한 자동 주파수 제어 계통개선 \circled2 기존발전소 성능과 이용을 향상을 위한 재가동(Repowering) 등의 리 엔지니어링 \circled3 가스터빈 복합화력과 열병합발전(Co-generation) 등과 같이 건설기간이 짧고 비용이 적게 들며 송전 설비 건설도 불필요한 분산형 전원의 건설 \circled4 수력발전소와 조력발전소의 건설 \circled5 양수발전 등 전력에너지 저장설비의 개발 \circled6 송전전압격상과 배전방식개선 및 종합전력정보시스템 구축 \circled7 남ㆍ북한 전력계통 내지는 동북아시아 전력계통을 연계하는 평화망사업(Peace Network Project)등의 추진이 경수로 사업에 선행되어야 한다. 특히 러시아, 중국, 한국, 일본의 발전 에너지원 분포와 년간 부하곡선을 고려할 때 동북아시아 전력계통의 연계는 관련국 상호간에 에너지 환경과 경제적 측면에서 상당한 이득과 안정성을 강화해 줄 것이며, 기술발전과 평화공존에 크게 기여 할 것이다. 이를 위하여 관련국의 전력계통연계 전문가들이 참여하는 남\ulcorner북한전력 계통연계연합회(Co-Pia ; Co-rea Power Systems Interconnection Association)와 동북아지역전력 계통연합회(Near Pia=North-Eastern Asia Region Power Systems Interconnection Association)의 구성을 제안하는 바이다. 주요용어(Key Words): 자동주파수 제어(AFC), 리엔지니어링(Re-Engineering), 분산형 전원(Dispersed Generation System), 전력저장(Power Storage), 부하조절기(Load Conditioner), 수요관리(DSM) 연계(Interconnection), 인터시스템(Intersystem), 통합자원계획(IRP), 안전성 강화(Security Enhancement), 전력시장개방(Electricity Free Maket), 통일비용(Unification Expense, Unification Cost), 남ㆍ북한전력계통연계연합회(Co-Pia), 동북아지역전력 계통연계연합회(Nea,-Pia).

  • This study aims to propose measures to support students' English literacy development in collaboration with public libraries in the community. The literature review shows that students can improve their English literacy skills by not only reading authentic books, but also participating in English literacy programs at the public library. The analysis of the gathered data reveals that public libraries provide extensive programs customized to students' needs. It is also shown that reading programs at the public libraries play an important role in improving students' literacy skills. With the analysis of the literacy programs at various libraries nationwide or abroad, we can understand the importance of the English literacy programs. Especially English Literacy programs in public libraries can be more effective to improve students' English literacy skills. It is suggested that we need to support children's literacy development in collaboration with public libraries in the community.

  • 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.

  • 연계지역 전력시장 간의 에너지 거래는 전체 전력시장의 사회적 편익을 향상시키기 위해 이루어진다. 기존의 연계지역 전력시장 간시장 최적화 문제를 다루는 중앙처리 접근방식은 경쟁적 전력시장 환경하에서 적합한 모델이 아니다. 본 논문은 연계지역 전력시장 문제를 다루기 위해 보완 라그랑지안 승수 기법(Augmented Lagrangian Relaxation) 기반의 분산처리 최적화 방법을 제시한다. Block Coordinate Descent(BCD) 분산처리 기법이 보완 라그랑지안 승수의 최적화 문제를 분리하기 위해 적용된다. 연계시장 모델을 구현한 사례연구를 통해 제시된 알고리즘의 효용성을 입증한다.

  • This exploratory study analyzed the structure of collaborative network among small libraries. The survey was conducted with the small libraries in Bucheon region. In order to analyze the structural features of the network, this study used social network analysis methods. The results of the study indicate that public small libraries has high density networks with other small libraries and performed a central role in the whole network. Private small libraries were, however, isolated in the whole network indicating their weak collaboration with other small libraries.

Effects of Community-Based SSI Programs on Promoting Middle School Students' Understanding of Issues and Character and Values as Citizens: Focused on Fine Dust Issues (지역사회연계 미세먼지 교육프로그램이 중학생들의 이슈에 대한 이해와 시민으로서의 인성과 가치관 함양에 미치는 효과)

  • The purpose of the study is to investigate the effects of community-based SSI programs (SSI-COMM) regarding "fine dust" on promoting middle school students' understanding of community issues and their character and values as citizens. SSI-COMM on fine dust was implemented in 4 middle schools located in Seoul, and 151 7th graders participated in the program lasting over 8 weeks. Data was collected through two questionnaires (i.e. students' understanding of issues, and character and values as citizens) and individual interviews with selected students. Results indicated that there were statistically significant increases in their understanding of fine dust issue after the program. In addition, the program significantly contributed to enhancing students' character and values, especially in the domains of social and moral compassion and socioscientific accountability. Student interviews revealed that they became more aware of the local community problems caused by fine dusts and started to consider what efforts should be made to solve them. They also felt individual responsibility for the occurrence of fine dust, and the need for participation and practice of community activities for vulnerable groups in affected areas.

  • When evaluating the feasibility of construction projects of large-scaled transportation facilities such as roads or railways based solely on the result of the economic analysis, less development indicators are politically reflected on the investment decision-making because regions whose socio-economic indicators are poor may be disadvantaged or underserved for the projects. Existing less development indicators, however, does not consider the transportation connectivity which indicates how effective the transportation networks are established for the transport of people and goods. In this study, travel time contour maps, travel distance and travel time between regions, and a route curvature were utilized to define new indices which reflect transportation connectivity on the less development indicators. When the new indices are applied, the existing rankings of under-developedness were changed, which means that transportation connectivity could effect on the political decision. In this study, we also suggested the necessity of considering the transportation connectivity when evaluating less development indicators, developed measures of inter-regional linkages, and performed the whole procedures of combining existing and new indices to evaluate the less development indicators.
