Recently, the number of closed rural schools is increasing due to the decrease in school age population. This study aims to comparative analysis of utilization policies for closed schools in Korea and Japan. The results are as follows. First, Both Korea and Japan was expected to increase the number of closed schools since the standard of abolition of small schools has been strengthened. Second, In Korea, it was possible to know the detailed information of closed schools through 'Eduinfo' website, but it was hard to know the detailed information of utilization cases of closed schools. On the other hand, Japan not only provided information about the unused school facilities but also introduced the utilization cases of closed schools and financial support system for utilization of closed school. It was characterized by linking with the information of unused schools and company, NPO, elderly welfare facility, etc. Third, In korea Superintendent established plans to use closed schools to respond flexibly to local circumstances. Japan simplified the procedures for closed schools to promote the utilization of closed schools. Finally, In Japan, there was various financial support system. But in Korea, it supported the cost of subsidy reduction, free loan, maintenance and management and operation.

In order to present the enhancement direction for the military administrative facilities, that can satisfy the user demands and achieve cost-effectiveness the goal of public projects, this research analyzes the features of functional spaces using Analytical Hierarchy Process(AHP). Basically, the scope is selected to four facilities commander office, private office, public office, and meeting room, because they have an effect on military administrative facilities. Since the space is established by a combination of their own functions, this research begins with an analysis of functional spaces of military administrative facilities, which is verified through literature review and interview with expert. Thereafter, an AHP survey is conducted to military personnel to analyze the priority of functional spaces and to re-classify the functional spaces of each Military administrative facilities. Resultingly, the difference of functional spaces preference according to ranks and facility type are identified. Even though the same military facilities, it means that user satisfaction is different. Therefore, user satisfaction should be considered for each facility at the construction plan. It can minimize overlapped and unused spaces, which can help ensure cost-effectiveness. Consequently, this research suggested the methodology and the process that can take user satisfaction and can support the enhancement of military facilities standards.

In order to reduce greenhouse gas emissions in recent agricultural energy and increase the energy self-sufficiency rate of each farmer, it is extremely important to expand the supply of solar energy using unused space of agricultural facilities, roof. This study surveyed and analyzed the environmental and administrative factors such as problems according to the structure, azimuth and latitude of broiler houses and stability of standard broiler houses required to use broiler house roof based on the poultry houses in Sangju-si. The results can be summarized as follows: 55.6% of the solar energy facilities of according to the classification of arable lands of broiler houses were available, and 31.7% of them were available by classifying according to the azimuth. However, 20.6% of them were available in the survey considering all the arable land and azimuth. In the roof inclination of the broiler houses, from 20 to $25^{\circ}$ was the most common, 30 broiler houses. The broiler houses with the roof inclination more than $20^{\circ}$ accounted for 63% of the total. It was considered that the inclination was generally proper. In the structural safety, only 3 broiler houses that were constructed as a standard broiler house were available. In practice, all but one broiler house was inappropriate to expand the solar energy project using roof. The solar thermal facility weighed $63.6kg/m^2$ in total: the frame and solar thermal collector weighed $27.8kg/m^2$ and $35.8kg/m^2$, respectively. The standard broiler house required to be internally reinforced. This study suggested a plan for internal reinforcement and a feasible plan because there were problems with structural safety when installing solar thermal and photovoltaic systems.

With population losses and stagnant or depressed economies, the local governments embrace shrinkage and accept having a significantly smaller population. Both the initial and ongoing causes of shrinkage hold dramatic effects on the city and its remaining residents. In this context, vacant land increases as an overabundance of unused infrastructure is demolished and municipalities become burdened with increasing maintenance costs of this land. The result is that vacant land often experiences minimal management relative to social norms and have chance to provide a setting for ecological processes with urban rightsizing strategy. Therefore, urban ecosystems undergo major shifts in structure and function. We need to better understand the possibilities of where and how much of houses and land will be abandoned to assist land planners and policymakers to mitigate conflict between optimal ecological and sociological outcomes. This article, therefore, aims to identify distributional characteristics of vacant houses and lands with case study of Mokpo. The study found and verified affecting factors of vacant houses and lands by type through the use of a Maxent model and spatial data that explained housing choice and preference theory. We can predict the vacancies with the spatial variables such as land price, the population ratio over 65, and the distance from security facility. Based on the analysis, the ways of managing housing and land vacancy for sustainable development and ecological restoration method are discussed.

This study purposed to discover whether or not academic libraries reflect these changing roles. We selected K University as the research target and surveyed user satisfaction of materials, staff services, facilities, electronic devices, media, and so on. The research findings are as follows: 1) the frequency of library visits of University K was on the high side, 2) the primary purpose of using the academic library was associated with learning or reading, therefore, the most used library spaces were related to that, 3) the most used library materials were 'general books', the most unused were 'reference books', 4) the most preferred way to obtain needed materials when failing to find wanted materials was 'Contact librarian'. A similar phenomenon occurred in terms of facility use, 5) university K's users were usually satisfied with the loan policy, 6) the rate of users who don't know whether there is user education was very high, the rate of users who have no experience with user education was extremely low. These research findings can be referenced by library management to improve libraries' service quality and take advantage of complex spatial configurations.

이 논문은 그린 딜로 인한 전기 에너지 수요가 급증을 될 수 있기 때문에 이를 제시하고자 한다. 그러나 미래의 전기자동차와 많은 전기 에너지의 조달은 여전히 화석 연료에 의존한다. 이에 IT 산업의 중요성이 부각되고 수소-전기차의 수요와 연관 산업으로 그 수요가 증가하게 된다. 본 연구의 방법은 IT 산업의 전기 에너지 수요보다 미래 차세대 동력으로 전기차의 충전과 연관성을 조사하였다. 이는 실증적 회귀 분석을 통해 경제 성장에 따른 산업용 전기와 가정용 에너지를 성장에 따른 PPP의 상관관계를 도출하였다. 그 결과 전기차와 차세대 전기차를 포함한 변화량은 GDP 대비 구매력 변화 국가의 1/3에서 유의미한 것으로 나타났다. 이는 전기차의 수요가 있는 32개국 중 12개 국가(이탈리아, 캐나다, 스위스, 폴란드, 슬로베니아, 독일, 슬로바키아, 핀란드, 스웨덴, 체코, 에스토니아, 덴마크)가 더 많은 전기 에너지에 더 민감하기에 전체 구매력에 영향을 미치게 된다. IT-전기 에너지원의 미사용 전력 낭비를 방지하고, 수소전기 충전-보존함으로써, 향후 성장을 위한 수급에 국가의 IT 산업 보존 완충 시설대비가 필수불가결하다.

현재 반도체 공정에서 다양한 by-product 및 미사용 가스가 배출되고 있다. 오염물질을 함유한 배기는 일반적으로 유기, 산, 알칼리, 열, 캐비넷 배기 등으로 분류하며, 각각의 배기 특성에 맞는 대기 방지설비에서 처리 후 배출된다. 유기 배기 물질로서 휘발성 유기 화합물(volatile organic compound, VOC)은 산소 함유 탄화수소, 유황 함유 계 탄화수소 및 휘발성 탄화수소를 총칭하는 물질이고, 알칼리 배기의 주요성분은 암모니아(NH₃), 수산화테트라메틸암모늄(Tetramethylammonium hydroxide, TMAH)등이 있다. 본 연구의 목적은 유기와 알칼리 배기가스를 동시에 처리하기 위해 직접 연소 및 로 내 온도를 일정하게 유지하여 연소 특성 파악하고 NO_X 저감률을 분석하고자 진행하였다. VOC는 Acetone, IPA(isopropyl alcohol), PGMEA(propylene glycol methyl ether acetate)을 사용하였으며, 알칼리 배기 대표 물질로는 암모니아를 사용하였다. 실험 변수로는 온도와 당량 비(equivalence ratio, ER)로 배기가스 특성을 살펴보았다. 물질별 단독 및 혼합 연소테스트를 진행하였다. VOC 단독 테스트 결과 당량 비 1.4 조건에서 완전 연소가 일어남을 확인하였다. 암모니아는 당량 비 감소에 따라 산소 및 질소산화물의 농도가 감소하였다. 혼합 연소 운전 결과 배기가스 조성 내 질소산화물의 대부분은 일산화질소였으며 이산화질소는 10 ppm 부근으로 검출되었다. 전체적으로 질소산화물의 농도는 반응온도가 증가하면서 산화반응이 활성화되어 감소하는 경향을 나타나지만 이산화탄소의 농도는 증가하는 경향을 확인하였다. 전기열원을 적용한 무 화염 연소 기술을 적용하였을 때 VOC 및 암모니아 연소가 원활하게 일어남으로써 현재 별도로 운전되는 유기 및 알칼리 배기 시스템보다 경제성 및 공간적인 측면에서 장점이 있다고 판단된다.
