In addition to anthropogenic origins, fluorine (F) is naturally enriched in rocks due to geological events, such as magma dissemination, hydrothermal alteration, mineralization, and fault activities. Generally, it has been well known that F is chiefly enriched in the region of igneous and metamorphic rocks, and biotite granite was mostly distributed in the study area. The F enrichment mechanism was not sufficiently elucidated in the previous studies, and the study on a fault zone was conducted to reveal it more precisely. The mineral composition of the fault zone was identical to that of the Eulwangsan biotite granite (EBG), but they were quantitatively different between the two areas. Compared with the EBG, the fault zone showed relatively higher contents of quartz and F-bearing minerals (fluorite, sericite) but lower contents of plagioclase and alkali feldspar. This difference was likely due to hydrothermal mineral alterations. The results of microscopic observations supported this, and the generation of F-bearing minerals by hydrothermal alterations was recognized in most samples. Accordingly, it might be interpreted that the mineralogical and petrological differences observed in the same-age biotite granite widely distributed in the Yongyudo was caused by the hydrothermal alterations due to small-scale geological events.

자율운항선박의 효과적인 운영을 위해서는 자선 주변 해상 환경의 장애물 및 자선, 타선에 대한 통합적인 상황인식 정보가 요구된다. 상황인식은 현재의 시점에서 관측되는 정보를 바탕으로 운항 해역에 대한 종합적인 인식과 함께 가까운 미래에서 발생할 수 있는 위험 상황 및 비정상 상황에 대한 추론까지를 포함한다. 본 연구에서는 이러한 자율운항선박의 원격 상황인식을 위한 기초연구로써, 선박자동식별시스템 AIS의 항적 정보 분석에 대한 내용을 수행한다. AIS에서 얻어지는 항적 정보를 이용한 해상 상황인식을 수행하기 위한 전처리 과정으로써, 손실 데이터에 대한 보간 방법에 대한 연구를 수행한다. 구체적인 방법론은, 추적필터를 이용한 보간 방법과 항적 정보 학습 기반의 보간 방법을 적용하였으며, AIS에서 얻어지는 실제 항적 데이터를 이용하여 초기 결과를 검증하였다.

The aim of this study is to propose the effective management plan for (New) Library at International Science Business Belt in Korea. For this purpose, this study analyzed cases of domestic and overseas libraries which have been providing the special Science Business Service. Also user questionnaire surveys were conducted for the user demand in (New) Library. Based on case studies and user surveys, the management plan for ISBL was suggested as follow with its division into five realms; that is, information resources and special programs, manpower, space facilities, internal cooperation and international network. The research could be used as basic resources for the International Science Business Library in Korea.

The essential role of the Division of Earth Sciences(EAR) in the Directorate of Geoscience(GEO) of National Science Foundation of America(NSF) is to support basic research aimed at acquiring fundamental knowledge of the Earth system that can be directly applied to the United States' strategic needs. The 2011 Committee on New Research Opportunities in the Earth Sciences(NROES) of the National Academy of Sciences(NAS) identified specific areas of the basic earth science research scope of the EAR that were poised for rapid progress during the next decade. Quantified by interdisciplinary approaches, the Committee highlighted the following topics relating to the EAR Deep Earth Processes and Surface Earth Processes sections: (1) the early Earth; (2) thermochemical internal dynamics and volatile distribution; (3) faulting and deformation processes; (4) interactions among climate, the Earth surface processes, tectonics, and deep Earth processes; (5) co-evolution of life, environment, and climate; (6) coupled hydrogeomorphic-ecosystem response to natural and anthropogenic change; and (7) interactions of biogeochemical and water cycles in terrestrial environments. We also promote future research challenges such as the critical zone studies. In order to promote more active such a huge future research challenges, additional research support policies are needed.

The purpose of this study is to propose a strategy model for engineering education for citizen through the connection between colleges of science and engineering and science museums as a way to achieve citizen science. For this model, the role of universities was redefined as social contributions through engineering education from the perspective of knowledge triangle and university entrepreneurship. In addition, the science museum was re-examined as an engineering education platform and selected as an institution that supports the contribution of colleges to society. For practical model development, the connection types of these two institutions were analyzed as case studies and interview to collect opinions from experts in the science museum. In this process, convergence education content development, reinforcement of college-science museum linkage, infrastructure construction, development of college resource utilization plans, and maintenance and expansion of educational programs diversification were derived as components for model development. Based on this, engineering education model for citizen was presented that matches educational programs according to the type of participation of colleges including key factors and considerations.
