본 연구에서는 수질오염 관리 측면에서 유역의 취약성을 평가하고 우선 관리가 필요한 지역을 선정하는 기법을 수립하고자 한다. 수질은 다양한 요인에 의해 영향을 받기 때문에 오염의 취약성을 평가하기 위해 다기준 분석 기법을 적용하였다. 다기준 평가기법은 다양한 평가 항목이 포함되는 의사결정 문제에 유용하다. 연구 절차는 평가 항목 및 가중치 결정, 항목별 평가자료 구축, 수질오염에 대한 취약성 평가 후 수질오염 관리가 필요한 유역 선정의 단계로 구성하였다. 평가 대상은 814개 소유역이다. 평가 프레임워크는 오염원, 확산 과정, 수자원 현황의 3개 그룹으로 구성되며, 각 그룹에 대한 하위 평가 항목을 선정하였다. 오염원 그룹은 중앙 및 지방 정부에서 제공하는 오염원 조사 결과, 농업 분야 자료, 토지 사용 현황 등을 적용하였다. 확산 과정 그룹은 강우, 토지 피복, 토양 등의 데이터를 사용하였으며, 수자원 현황은 하천의 흐름, 수질 및 수생 생태계 현황 등이 반영되었다. 유역 단위로 모든 항목에 대하여 가중치를 반영한 점수를 집계하고 취약지역을 선정하였다.

The purpose of this study is to explore ways for students to connect conceptual and procedural knowledge in mathematical modeling lessons. Accordingly, we selected the greatest common divisor among the learning contents in which elementary school students have difficulties connecting conceptual and procedural knowledge. A mathematical modeling lesson was designed and implemented to solve problems related to the greatest common divisor while connecting conceptual and procedural knowledge. As a result of the analysis, it was found that the mathematical modeling lesson had positive effects on students solving problems by connecting conceptual and procedural knowledge. In addition, through actual class application, a teaching and learning plan was derived to meaningfully connect conceptual and procedural knowledge in mathematical modeling lessons.

Japan enacted the "Designated Radioactive Waste Final Disposal Act" for the geological disposal of high-level radioactive waste in 2000 and began the site selection process. However, no local government wanted to participate in the siting process. Therefore, in 2015, the Japanese government developed a new site selection process during the literature survey step, and on June 28, 2017 they published a "Nationwide Map of Scientific Features for Geological Disposal" created with the aim of promoting public participation from local governments. This map illustrated the requirements and criteria to be considered in the early or conceptual stages of securing a geological repository and was useful for improving public understanding and exchanging opinions with local governments by analyzing the suitability of different geological disposal sites.

Dashboard camera is important system to store the variable data that not only video but also non-visual information that state of vehicle such as accelerometer, speed, direction. Non-visual information include variable data that can't visualization, so it used important evidence to figure out the situation in accident. It could be missed to non-visual information what can be prove the case in the just digital video forensic procedure. In this paper, We proposal the digital forensic analysis procedure for dashboard camera to all data in dashboard camera extract and analysis data for investigating traffic accident case. And I analyze to some products in with this digital forensic analysis procedure.

The reasonable decision making procedure for conducting follow-up management of water-friendly riverfront have been proposed in the national streams when the use of the level of usage for facility becomes degraded. It consists of two part usage: the selection of destination and the follow-up strategy with the alternatives. Considering the water-friendly riverfront grade derived from prior research, Grade IV and V were selected as candidates, and if the economic utility became low, it should be selected as candidates for the follow-up management. In addition, the basic plan for follow-up management was reviewed and alternatives suitable for the strategy could be derived considering the need for the operation of water-friendly riverfront in target site. The prior study on the follow-up decision making process of the water-friendly riverfront has not yet been confirmed, but since the life cycle of such facilities become almost expired, systematic procedures are needed to enable the use of administrative procedures for users' convenience and safety.

원자력발전소의 건설은 막대한 비용과 시간이 소요되는 기한산업이므로 발전소의 수지선정, 설계, 제작, 건설에 이르는 건설단계에서는 철처한 안전대책, 품질관리 및 검사확인을 체계적으로 하는 것이 완전확보의 관건이 되며 운전단계에서는 절차주수와 성능유지가 가장 중요한 요소이다. 본고에서는 이러한 안전대책 현황을 포함하여 현재 진행되고 있는 개선노력을 기술하였다.
