본 연구에서는 원전 내부에 위치한 기기에 대해 지진취약도 평가를 수행하였다. EPRI에서 제시하고 있는 확률론적 지진 응답 해석을 통해 먼저 구조물 응답인 층응답스펙트럼(FRS)을 도출한 후 이를 지진요구값으로 사용하였다. 취약도 곡선 작성 후 기존의 결정론적 지진 응답 해석 방법과 비교 결과, 취약도가 더 높았다. In this study, a seismic fragility assessment was performed for an equipment housed in a nuclear power plant. A set of floor response spectra(FRS) was rendered by probabilistic seismic response analysis, which is suggested by EPRI. The FRS, responses of the structure, were then used as seismic demand for the equipment. A consequent fragility curve exhibited greater fragility when compared to that of a conventional deterministic seismic response analysis.

The remote electronic laboratory proposed and implemented as a solution for the problem of lack of reality in virtual education. The system provides functions with which learners can perform experiments by remote-controlling circuits and equipment related to experiments and practices on the Web and gets data and image information, so through it learners can make realistic experiments at any time and in any place. The remote laboratory for electronic circuit experiments allows learners to control high-priced measuring equipment and get data and images of circuits being tested. A web-based realtime remote laboratory proposed and implemented in this thesis is an alternative that reduces financial burdens for purchasing, maintaining and repairing high-priced measuring equipment and overcomes spatial and temporal limits in moving between laboratories. In addition, it can be utilized as a solution for the problem of lack of reality inherent in virtual experiments.

원전 벽체의 특성을 고려한 벽체 강도 평가 방법을 제시하였다. 개발된 방법의 확률 특성을 바탕으로 지진취약도평가를 수행하고, 벽체의 내진성능을 확률론적으로 평가하였다. A numerical procedure to predict shear strength of a wall in nuclear power plants was proposed. Based on the probabilistic distribution of the proposed model, seimsic fragility analysis was performed and probabilistic seismic capacity was presented.

In this paper, We implement a record of students attendance about a lot of subjects being done by a student and a professor in educational system. The student administration system beased .NET deals effectively with affairs about a control service of students. The system is largely divided into student administration server system, student administration client system, and a record of students attendance system. The student administration sever system is made of database, web server and system control server. The client system is made of a student administration module for a professor and taking a lecture administration module. Finally, the student attendance system is made of an auto-attendance machinery and an attendance check module. The auto-attendance check is proceeding through a bar code perception.
