Due to the transformation to the intelligent information society, the rapid change of our life and environment is expected. The Ministry of Science and ICT (MSIT) and the National Research Council of Science and Technology (NST) introduced a five-year government supported research institution's planning and evaluation based on the mid-to long-term perspective. This study collects international benchmarking information including industry, academia, and research fields by collecting mid- and long-term strategy reports from public research institutes, surveys by experts from abroad universities and research institutes, and analyzing overseas market information reports. The British Geological Survey (BGS), the U.S. Geological Survey (USGS) and the japanese geological survey related institutes (AIST-GSJ) plans for three-dimensional national geological information, predictions of geological environmental disasters, and development of important metals and material in the low carbon economic transformation and in the era of the Fourth Industrial Revolution. The mid- and long-term program emphasizes basic and public research on geological information through abroad experts survey such as the IPGP-CNRS etc. The market analysis of the mining automation and digital map sectors has been able to derive the fields in which the role of public research institutes by the market is expected such as data collection on land and in the air, mobile or three-dimensional information production, smooth/fast/real-time maps, custom map design, mapping support to various platforms, geological environmental risk assessment and disaster management information and maps.

통상적으로 국외도입부품의 가격은 그 모체장비의 수명이 경과하여 도태시기로 갈수록 가격이 급격히 상승하며, 심지어는 우리가 아무리 많은 비용을 지불하더라도 조달이 곤란한 경우가 많이 발생한다. 따라서 유사시 원활한 군수지원을 위해서는 국내에 안정적인 조달원을 유지하여야 하며, 이것이 적기 군수지원과 경제적인 조달을 위한 최선의 방안이라는 점이다. 이 글에서는 군용물자의 부품 군산화와 관련된 전반적인 정책과 지원제도에 관한 문제점을 도출하고 부품국산화를 활성화 시킬 수 있는 개선방안을 제시하고자 한다.

석탄을 가장 효율적으로 깨끗하게 이용할 수 있는 석탄가스복합발전(IGCC)의 향후 실용화 시기를 전망해 보면 국외에서는 1995년 이후에 상용발전소가 운용될 것으로 예상되며 국내에서도 환경규제가 강화되는 1996년 이후 2005년경에는 석탄가스화복합 발전소를 건설할 수 있을 것으로 판단된다. 석탄가스화 복합발전소의 국내 도입은 전력수요증가 투자재원 및 실용화시기 등을 감안하여 신규에 석탄가스화로를 추가 설치하는 설비개조 방안이 있으며, 가스터빈발전기 설치후 증기터빈발전기와 석탄가스화로등을 적절한 시기에 단계적으로 건설하는 단계적 건설등으로 추진할 수 있다.

This study analyzed the difference between the two situations to verify the effectiveness of the book selection by the subject professionals in a academic library. In this, some circulation statistics before and after introduction to subject specialists were compared. Moreover, by using Minitab and t-test, ANOVA among other statistical techniques, 186,435 books selected 3 years before September 2005 and after 3 years and 622,213 circulation statistics about those books in 'S' University Library were compared and analysed. The results were as follows: (1) After introduction to the subject librarian, the proportion of books selected by librarians were increased. (2) After introduction to subject reference librarian, the foreign books selected by the faculty and the librarians were statistically significantly increased. (3) By academic field, the academic fields of the books selected by the faculty were significantly increased, but the academic fields of the books selected by the students were significantly decreased.

오늘날 수소는 화석연료와 다르게 친환경 측면, 신사업 창출 및 국내 에너지 안보 확대 측면에서 미래에너지원으로 각광받고 있다. 이에 따라 세계 유수의 자동차 기업들이 궁극의 차량이라는 수소전기차 기술 개발 및 상용화에 주력하고 있으며 각국은 자국의 수소인프라의 핵심인 수소충전소 구축 전략을 강화하고 있다. 또한 수소전기차 초기 보급을 활성화하기 위해 국가 지원하에 수소충전소 공급을 적극 추진하고 있다. 전 세계적으로 500개 이상의 수소충전소가 건설, 운영 및 계획되고 있다. 국내에서도 수소전기차, 수소버스 및 수소트럭 등 보급 계획과 더불어 이에 필요한 수소충전소 공급 로드맵을 연도별로 발표하는 등 수송분야에 수소 에너지 도입이 강력하게 진행되고 있다. 그러나 우리나라 수소충전소 구축에 필요한 설비 등은 아직 자체 조달이 거의 이루어지지 않아 많은 설비 및 부품들이 국외 도입에 따른 여러 문제점들로 인해 어렵게 구축된 많은 수소충전소 운영이 원활하지 않은 상황이다. 따라서 국내외 수소충전소 구축 현황 및 계획에 대해 정리 및 분석하여 국내의 수소충전소 구축 및 운영에 대한 이슈들을 알아보고 해결해야 할 과제는 어떤 것이 있는지 알아보고자 한다.

A number of BTL projects for educational facilities have been augmented because of the increase of newtown development and deflationary policy of class size for learning efficiency. As the operation and maintenance costs rapidly increase, the budget for operation and maintenance is expected to be short. Therefore the asset management maximizing asset value is required to clarify the budget plan and distribution and provide a qualitatively high service. The main objective of this research is to establish asset valuation process in educational facilities delivered by BTL project. In order to meet the research objective, the asset valuation process is established by literature reviews, expert advice, and lessons learned from the developed countries. The developed process includes depreciation by internal accounting law, the core element of valuation, and asset valuation process. The results of the research will be help to offer the qualitatively high service and explain the standard of budget plan. It will assist commencing the asset management system.

In the early construction phase of the Korea Train Express (KTX), the Movable Scaffolding System (MSS) for the top structure of the bridge was the predominant construction method. But the method had to be changed due to arising problems and an alternative method had to be found. Company H that participated in Korea Train Express construction project achieved excellent results of performance through the introduction of the Precast Span Method (PSM), which has been previously successfully employed in foreign express train projects. This study intends to verify the superior performance of PSM over MSS in the KTX construction process by conducting a comparative analysis on PMS and MSS based on the field experience of company H. This study will not only help to understand PSM, which is expected to expand its future scope of application, but also contribute to solve the problems of PSM that occurred during the construction phase.

The purpose of this study is to explore alternative ways of teaching derivatives in a way that emphasizes intuition. For this purpose, the contents related to derivatives in Korean curriculum and textbooks were analyzed by comparing with contents in Singapore Curriculum and textbooks. Singapore, where the curriculum deals with derivatives relatively earlier than Korea, introduces the concept of derivatives and differentiation as the slope of tangent instead of the rate of instantaneous change in textbook. Also, Singapore use technology and inductive extrapolation to emphasize intuition rather than form and logic. Further, from the results of the exploration of other foreign cases, we confirm that the UK and Australia also emphasized intuition in teaching derivatives and differentiation. Based on the results, we discuss the meaning and implication of introducing derivatives and teaching differentiation in a way that emphasizes intuition. Finally, we propose the implications for the alternative way of teaching differentiation.

The fish community and introduced fish were surveyed at eight stations of Lake Soyang from March to October, 2013. A total of 41 species of twelve families were collected from the survey stations and among them, two species: Hemibarbus mylodon and Siniperca scherzeri (albino type) were identified as natural monument. There were fifteen Korean endemic species (36.6 %) including Acheilognathus yamatsutae. When compared with previous data (2003), A. yamatsutae, Pseudorasbora parva, Sarcocheilichthys nigripinnis morii, Sarcocheilichthys variegatus wakiyae, Orthrias nudus, Leiocassisuss ussuriensis, Oncorhynchus mykiss, and Micropterus salmoides appeared new in the lake. Dominant species were Hypomesus olidus (St. 1, 3, 6, 7, 8), Lepomis macrochirus (St. 2, 4) and Zacco platypus (St. 5). Of the 12 introduced species fishes in Lake Soyang, Anguilla japonica, Hemiculter eigenmanni, H. nipponensis, Rhinogobius giurinus and Tridentiger brevispinis were introduced and released from other native river water zones in Korea but Cyprinus carpio (Israeli type), Carassius cuvieri, O. mykiss, Ictalurus puntatus, L. macrochirus, and M. salmoides originated from foreign countries.
