최근 국내의 전자, 금융, 전기, 서비스, 제조, 제약 등 기업의 형태를 막론하고 악의적인 해커를 통해 기업 보안사고가 발생되고 있으며 이로 인한 기업정보 손실의 피해가 매년 꾸준히 늘어가고 있다. 이에 대응하기 위해 국내 대다수 기업들은 기업 활동과 관련된 중요 정보를 보호하기 위해 노트북, 스마트폰, 태블릿 내 다양한 Endpoint 보안솔루션을 도입하고 있다. 그러나 무분별하게 도입되고 있는 Endpoint 보안솔루션 간에는 과다 예산, 동일한 기능으로 인한 충돌이나 성능 저하 등의 문제들이 발생하고 있으며, 이로 인한 추가적인 유지비용, 충돌 문제를 해결하기 위한 노력은 보안부서의 IT운영상의 새로운 어려움이 되고 있다. 본고에서는 이러한 Endpoint 보안솔루션 도입 및 운영상의 문제를 해결하기 위해서 PC를 중심으로 정보보호 거버넌스에 기반한 Endpoint보안 솔루션 도입 결정을 위한 프로세스를 마련하여 해결 방안으로 제시하고자 한다.

This study aims to present the re-structuring strategies of healthcare facilities in Kwang-ju and Jon-nam province for it's competition power in the emerging global health care market. Kwang-Ju city and Jon-nam province have had difficulties in building a balanced healthcare system because of rapidly declining population, weakened healthcare infra-structure and geographical problems of healthcare supply by numerous islands. Now, Kwang-Ju city and Jon-nam province try to be a core place of economy and culture in the west-south asia. To do so, it is fundamentally necessary to reform their current social structure including healthcare system in large scale. This Study presents the current conditions and the problems of healthcare environment in these areas.

Modern power system is operated and managed in closed network environment with treating a great variety of data, and requirement of real time power system data is more increasing. However, it is difficult for operators to fast evaluate the condition of power system using only isolation network system such as SCADA or EMS regarding unexpecting situations occurring. Recent technology achievement in areas of distributed computing, networking high speed communications and digital control as well as the availability of accurate GPS time source are rapidly becoming the enabling factors for the development of a new generation of real time power grid monitoring tools. In this paper, architecture of WAMAC which is the wide area monitoring and control system not only to control but also to monitoring in real time is proposed and the plan of integration interface with legacy system such as EMS for providing power system analysis base data effectively is suggested.

Recently, several problems have occurred in the space, infra-structure, and facility of the contiguity of existing harbors due to the trend of enlarged container vessels. In this regard, the Mobile Harbor has been proposed conceptually in this study as an effective solution for these problems. The concept is that of a transfer loader that transfers containers from a large container ship to the harbor on land, and is a catamaran type floating barge. The catamaran-type vessel is well known for its advantage in maneuverability, resistance, and effectiveness for working on board. For the safe and effective operation of the two floating bodies (a container ship and the mobile harbor in the near sea detached from the quay), robot arms, novel crane systems, and pneumatic fenders are specially devised with an additional mooring facility or DP (dynamic positioning) system. In this study, this concept is to be verified through comparison and simulation studies under various environmental conditions. It is shown that the proposed concept is in general feasible but there are several areas for further investigation and improvement.

Recently, Korea is becoming a world-leading country in various industrial fields with it's advanced information technology. In the 20th century, Korea went through a chaotic period from Japanese colonization via the Korean war to IMF because of lack of globalization. Now, we have a mission and the abilities to lead world-wide trends in entire fields of society. This study, comparing the modern healthcare planning trends in Korea, China, Japan and the United States, proposes the Northeast Asia Healthcare Network Plan which Korea leads. United States is the starter of healthcare network, but it's location is too far from Asia and IT is also inferior to the Korean. Japan seems to have no concerns with this healthcare network. And the current China is a rapid growing period and is too much for building its domestic healthcare infra-structure. they still have no concerns with re-structuring of healthcare system and facilities. Because of these reasons, I think Korea should have to lead Northeast Asia Healthcare network.

The purpose of this study is to derive periodical characteristics of the policy for the elderly in Japan by investigating the changes of social security system. The target period of 1946~2000 in Japan was divided into 3 periods for the understanding of periodical characteristics in the focuses of medical, welfare and pension system for the elderly; establishment of concept for the social security and welfare of Japan(1946,1950), appearance of social security system and the elderly problem(to late 1960's), infra construction for aging society(to late 1980's), development and reappraisal of practical policy for the elderly(to late 1990's). It is expected that this paper could provide basic data for the elderly-related policy making in our country.

As a result of rapid aging speed in our society, many problems related to elderly people have happened in many parts of our society. Among them, supply for elderly housing is one of the biggest problems. To solve these problems, 'long-term care insurance' has been put in operation from July 2008. By the time of the insurance operation, Ministry of Health and Welfare is increasing facilities every year according to '10-year expending plan of Care service infra' from 2002. As a result, the supply rate of elderly facilities has been raised. But the differences of facility supply rate between regions are very high in some cases. Therefore older people who need care sometimes cannot get proper care services in some areas. In that case, the frail older people have to use other care facilities of other regions. This is not a proper situation from the point of "Aging in Place". In order to prevent that case, it is necessary to set up proper 'Daily Living Spheres' and establish elderly care plan for it. Considering the points above, this study proposes the size of 'Daily Living Spheres' for the elderly, the kind and amount of elderly care facilities in it for the construction of Community Based Elderly Care System.

In various industrial sites, piping systems play an essential role in stable fluid supply and pressure maintenance. However, these systems are constantly exposed to risks of earthquakes, explosions, fires, and leaks, which can result in casualties or serious economic losses. With rapid advancements in the industry, different-sized piping systems have been launched; however, there are not enough maintenance personnel for troubleshooting and responding to situations where damages occur to piping systems. This increases the need for introducing autonomous damage management systems. In this study, a lab-based piping system was designed and manufactured by referring to the piping system of a naval ship to analyze the effectiveness of autonomous damage management systems. By using this testbed, a representative algorithm, the hydraulic resistance control algorithm, was realized and examinedIn addition, the difference between the averaged pressure and normalized pressure was introduced to improve the performance of the existing algorithm, which faces some limitations with regard to sensor noise and back pressure from the rupture-simulated pipeline part.

Stormwater reduction plays an important role in the safety and resilience to flooding in urban areas. Due to rapid climate change, the world is experiencing abnormal climate phenomena, and sudden floods and concentrated torrential rains are frequently occurring in urban basins and the amount of outflow due to stormwater increases. In addition, the damage caused by urban flooding and inundation due to extreme rainfall exceeding the events that occurred in the past increases. To solve this problem, water supply, drainage, and water supply for sustainable urban development, the water management paradigm is shifting from sewage maintenance to water circulation and water-sensitive cities. So, in this study, The purpose of this study is to examine measures to increase the resilience of urban ecosystem systems for urban excellence reduction by analyzing the effects of green infra structures and LID techniques and evaluating changes in resilience. In this study, for simulating and analysis of runoff for various stormwater patterns and LID applications, Storm Water Management Model (SWMM) was used.
