  • Nuclear power plants(NPPs) are consisted of power production functions and safety functions preventing leakage of radiation. Operators working in NPPs shall maintain these functions during an operation period through various activities such as improvement & modification, corrective maintenance, preventive maintenance and surveillance test. According to the performance of these work activities, there are configuration changes in NPPs systems. Its changes cause the increase of safety risks(CDF) and plant trip risks. Recently, the importance of risk management is increasing gradually in the operation process of NPPs. Therefore, this paper presents the work management methods using the various risk monitoring systems during power operation and overhaul period. Also this paper suggests the optimum application ways of risk systems for work management.

  • 우리나라의 488개 유인도 중 강수량 부족 혹은 지하수의 수질문제 등으로 상습적 식수난을 겪고 있는 도서지역은 237개에 이르고 있다. 이들 도서지역은 생활용수를 우물, 간이상수도, 운반급수 등에 의존하고 있지만 이중 47%의 도서는 간이급수시설이 전무한 실정이다. 2015년에는 인천시 옹진군의 소청도, 대청도에 장기간 지속된 가뭄으로 식수원이 고갈되어 3일에 1시간으로 급수를 제한하였고 이로 인해 식수난 문제 외 관광산업의 소득저하 등의 문제가 발생되어 원활한 물공급문제가 해결되지 않으면 도서지역의 위기는 심각할 것으로 우려된다. 도서지역의 기본권인 먹는 물 문제를 해결하기 위해 정부 및 지자체에서는 소규모 유인도서에 해수담수화시설을 설치하여 유지관리 및 운영을 위한 인력을 배치하고 수동으로 조작하거나 단순 자동운전에 의해 운영 및 관리되고 있는 실정이다. 본 연구에서는 해수담수화시설의 안정적이고 효율적인 운영을 위해 지능적 수운영 알고리즘을 개발하였다. 제어시스템, 감시시스템, 계측시스템 등의 ICT 기술과 연계하여 수요를 정확히 예측하고, 실시간 전력비용과 저류량, 사용량 등을 통합적으로 고려하였으며 적시정량을 생산하여 저장 및 공급하며, 목표수질과 수량을 원활하고 안정적으로 공급할 수 있도록 제어 및 감시를 통한 지능적 수운영을 목적으로 연구하였다. 데이터의 수집과 전송, 분석, 제어, 감시 활동이 유기적으로 결합되어 용수의 생산과 분배, 공급활동을 자동화함으로 운영상의 리스크를 줄여주며, 필요시 통합운영센터에서의 의사결정을 지원할 수 있도록 개발하였다. 향후, 해수담수화시설뿐이 아닌 일반 상수도 수운영에 있어서의 취수, 도수, 정수, 배수지관리, 송수, 관망관리까지 자동화된 시스템을 개발하여 지능적 운영관리가 가능하도록 알고리즘 모델 및 프로그램을 제시하고자 한다.

  • The total asset management system is used for banks or financial institutions for the management of trusteed assets or own assets and it is divided into three systems: the front-office system, the middle-office system and the back-office system by its business areas and functionalities. This kind of asset management system is a huge and complex system handling large data and various financial products, and requires professional knowledges like accounting, financial product specific knowledge, compliance and regulations, etc. It also performs high level computation for NAV calculation and risk measurement on every day Therefore, it needs absolute stability, extendability and efficiency and should handle the frequent change of regulation and products and connectivity with outdoor institutions. In this paper, we report our successful development of such a system and discuss issues regarding its efficient system design and system construction.

  • Microfinance has been an important tool for the economic growth and poverty alleviation. But the success factors and risk factors have not been synthesized in academic literature. This article has paid attention to success factors and potential risk of the Grameen Bank. Grameen Bank methodology is almost the reverse of the conventional banking methodology. Conventional banking is based on the principle that the more you have, the more you can get. Founder of Grameen Bank, Professor Yunus pointed out that, "The least you have the highest you have the priority to receive a loan". On the basis of theoretical literature, there have been different kinds of success factors of microfinance observed in this paper. Key success factors of Grameen Bank are like these: innovation, strict administrative structure, adaptation and learning practice, incentive system. Complementary services such as business consulting and brokerage will contribute to borrowers' economic performance development.

  • Physical security has always been an extremely important facet within the security arena. A comprehensive security plan consists of three components of physical security, personal security and information security. These elements are interrelated and may exist in varying degrees defending on the type of enterprise or facility being protected. The physical security component of a comprehensive security program is usually composed of policies and procedures, personal, barriers, equipment and records. Human beings kept restless struggle to preserve their and tribal lives. However, humans in prehistoric ages did not learn how to build strong house and how to fortify their residence, so they relied on their protection to the nature and use caves as protection and refuge in cold days. Through the history of man, human has been establishing various protection methods to protect himself and his tribe's life and assets. Physical security methods are set in the base of these security methods. Those caves that primitive men resided was rounded with rock wall except entrance, so safety was guaranteed especially by protection for tribes in all directions. The Great Wall of China that is considered as the longest building in the history was built over one hundred years from about B.C. 400 to prevent the invasion of northern tribes, but this wall enhanced its protection function to small invasions only, and Mongolian army captured the most part of China across this wall by about 1200 A.D. European lords in the Middle Ages built a moat by digging around of castle or reinforced around of the castle by making bascule bridge, and provided these protections to the resident and received agricultural products cultivated. Edwin Holmes of USA in 20 centuries started to provide innovative electric alarm service to the development of the security industry in USA. This is the first of today's electrical security system, and with developments, the security system that combined various electrical security system to the relevant facilities takes charging most parts of today's security market. Like above, humankind established various protection methods to keep life in the beginning and its development continues. Today, modern people installed CCTV to the most facilities all over the country to cope with various social pathological phenomenon and to protect life and assets, so daily life of people are protected and observed. Most of these physical security systems are installed to guarantee our safety but we pay all expenses for these also. Therefore, establishing effective physical security system is very important and urgent problem. On this study, it is suggested methods of establishing effective physical security system by using system integration on the principle of security design about effective security system's effective establishing method of physical security system that is increasing rapidly by needs of modern society.
