Recently, it is expected for requirement for more scientific research of weapon systems acquisition alternatives with reliability and objectivity. For these needs, study on methodology of weapon systems acquisition alternatives is but on-going, but it is still in its early stages and is unprofessional. We compared general decision making methods, government development program decision making methods, methodologies of weapon systems acquisition alternatives research such as AHP, ANP, KAAM and proposed AHP as weapon acquisition analysis. This study guarantees objectivity and derives scientific research results reliability by analyzing and comparing comprehensive elements such as cost, effectiveness, deployment schedule, program management risk. Further study on AHP weight and other decision making methods is needed considering category of weapon systems and program characteristics.

본 연구는 해안 및 도서지역에서 기후변화에 따라 재해위험이 증가되고 있으므로 '해일대비 신개념 침수방어벽 기술 개발'을 통해, 침수방어벽을 ICT와 연계하여 국민의 재산과 생명을 보호할 수 있도록 하는 연구이다. 이를 위해 국내·외 침수방어벽 자료를 조사하여 연구방향을 설정한 후, 국내·외 침수방어장치에 대한 개선방안을 제시하고자 한다. 기존 침수방어벽의 경우 ICT와 연계되어 있지 않아서 침수 예보나 경보 상황에 대응할 수 없는 실정이었다. 본 연구에서는 ICT 연계 방안을 제시하여 침수에 즉각적으로 대응할 수 있도록 함으로써 국민의 재산과 생명을 보호할 수 있도록 하고자 한다. 본 연구에서는 제시된 ICT 연계 침수방어벽에 대한 설치 대상지 검토 및 사업 대상 후보지를 선정하고, 조건별 수치모의(SWMM, 3D flow, FEM 등)를 통해 능력 검토를 수행하고자 한다. 향후 침수방어벽 시제품을 제작하면서 구조적인 안정성을 확보하도록 하였다. 침수센서의 경우 지주식으로 침수방어벽과 일체형으로 하고, 투명 침수방어벽의 경우 유리에 직접 디스플레이가 가능하도록 하였다. 본 연구에서는 기존에 보유하고 있는 직립형 고무보와 투명 홍수방어벽 기술에 대하여 재질과 구동방식, 시공성, 경제성, 유지관리 용이성 등을 재검토하여 해안 및 도서지역에 적합한 침수방어벽 기술에 대한 시제품과 운영시스템을 개발하고자 하며, 이를 통해 국민의 재산과 생명을 보호하고, 국내 물 시장에서 침수를 방지하여 국민경제에 기여할 수 있으며, 향후 ODA 사업에서 홍수예·경보 및 구조적 대책 분야에 진출하여 수출증대 효과를 얻을 수 있을 것이다.

Increased frequency of climate extremes is another face of climate change confronted by humans, resulting in catastrophic losses in agriculture. While climate extremes take place on many scales, impacts are experienced locally and mitigation tools are a function of local conditions. To address this, agrometeorological early warning systems must be place and location based, incorporating the climate, crop and land attributes at the appropriate scale. Existing services often lack site-specific information on adverse weather and countermeasures relevant to farming activities. Warnings on chronic long term effects of adverse weather or combined effects of two or more weather elements are seldom provided, either. This lecture discusses a field-specific early warning system implemented on a catchment scale agrometeorological service, by which volunteer farmers are provided with face-to-face disaster warnings along with relevant countermeasures. The products are based on core techniques such as scaling down of weather information to a field level and the crop specific risk assessment. Likelihood of a disaster is evaluated by the relative position of current risk on the standardized normal distribution from climatological normal year prepared for 840 catchments in South Korea. A validation study has begun with a 4-year plan for implementing an operational service in Seomjin River Basin, which accommodates over 60,000 farms and orchards. Diverse experiences obtained through this study will certainly be useful in planning and developing the nation-wide disaster early warning system for agricultural sector.

Companies engaged in the enterprise, while still at the start will have social responsibility. But recently, more and more companies will shorten the life expectancy of a corporate environment and is also rapidly changing. In this study, the longevity of global enterprises through the company's longevity factor analysis, that has continued to gain corporate answer. DuPont's global corporate giant Siemens and the longevity of the two factors in analyzing the factors that change the business portfolio, risk management, and continuous research and development, trust management, environmental management and other factors have been described. This ongoing internal and external environment analysis and core competencies by strengthening the implementation of responsible management as the core of the upcoming general management are appearing.

According to the increase of digital information, it comes to front to develop the policy about preservation of digital information, regarding it as national heritage. Especially, in recent years, KOREA has invested a lot of m to develop National Knowledge Database. So it is indispensable to preserve it permanently. This study categorizes knowledge information to 4 categories and suggests desirable direction for preservation policy and organization And design $\ulcorner$knowledge Creation$\cdot$Circulation$\cdot$Preservation system$\lrcorner$, which is expanded on current functional flow of Knowledge information.

국내외적으로 전력산업분야의 가장 큰 화두중 하나는 변전소 단위의 디지털화이며 특히 국외에서는 국제표준 변전자동화 시스템 연구와 제품개발 등에 인력을 집중 투자하고 있다. 국제적으로 지금까지 축적된 변전소 관련 제반 기술력 및 경험 둥을 바탕으로 전 세계적으로 단일화시키고 표준화된 변전소 자동화 규격인 IEC 61850 (Communication networks and systems in substations) 규격이 제정되었으며 따라서 향후 전력 관련 기업은 시스템 엔지니어링 기술, 전력기기 공급능력, 유지/보수/운영기술 등을 종합적으로 보유하고 자산 및 위험관리를 종합적으로 제공할 수 있어야만 세계시장에서 생존할 수 있다. 또한 전력기기를 수출하는 국내업체는 향후 IEC(International Electrotechnical Commission) 등 국제표준에 따른 전력설비를 개발하지 않으면 수출경쟁력을 잃게 될 것이다. 이러한 세계화 추세에 발맞추어 한국전력공사와 관련 업체들은 공동으로 2005년 10월부터 6년의 기간으로 "디지털 기술기반의 변전소 자동화 시스템 개발" 사업을 진행 중에 있으며 특히 한국전력공사는 변전자동화 시스템의 성능검증 및 실증시험 절차를 구축하기 위한 과제를 수행 중이다.

최근 몇 년간 국내 해양레저에 대한 관심 증가에 따라, 정부와 지자체의 해양레저산업에 대한 연구 지원 및 마리나 구축 사업 수행 등 해양레저 수요를 수용할 수 있도록 장비 및 시설 확보를 위하여 다양한 방면으로 노력이 한창이다. 그러나 아직까지 국내의 해양레저를 위한 시설 구축은 진행단계이다. 전국적으로 마리나 구축을 위한 작업이 한창이며, 이미 구축된 마리나에서 요트를 계류할 경우 관리하는데 드는 비용이 만만치 않아 사용자에겐 부담이 크다. 세일링 요트의 경우 span이 큰 모노킬이 부착되어있으므로 마리나 혹은 육상계류시설을 이용하지 않을시 모노킬이 파손될 위험이 있다. 본 연구에서는 서해안의 해양레저 대중화를 위해 누구나 안전하게 세일링을 즐길 수 있고, 두 개의 킬로 선체를 지지하여 육상 및 갯벌에서도 선체가 기울지 않고 설 수 있는 트윈킬 요트를 개발하여 보급하고자 한다. 기존 세일링 요트중 성능이 좋은 편인 야마하에서 제작한 블루워터21의 선형을 활용하였고 트윈킬은 블루워터21 모노킬의 면적 및 무게중심 등을 분석하여 개발하였다. 트윈킬 요트의 경우 모노킬 요트보다는 저항성능이 불리할 것으로 예상되므로 모형시험을 수행하였으며, 그 결과 모노킬과 트윈킬의 저항성능에 대한 차이가 예상보다 크지 않음을 확인하였다.

Chemical accidents can happen anywhere in the world. To prevent chemical accidents, Korea introduced the Chemicals Control Act. However, Small and medium-sized businesses do not meet these regulations. Accordingly, the Ministry of Environment is providing a chemical safety management support project for Small and medium-sized businesses. However, there are many small and medium-sized businesses, and businesses that need support need priority. In this study, the risk of the plants was classified into hig h, medium, and low risk based on four methods. As a result, out of 90 plants subject to the study, high risk was 30% and medium risk was 70%. The industries with the high risk were chemical products manufacturing and paint manufacturing. The plating and printing industries showed relatively medium risk. This risk classification has the advantage that it can obtain intuitive and quick results. These studies can be used as basic data for chemical safety management of local governments and Ministry of Environment.

Power generation construction projects involving large amounts of capital can affect the survival of a company along with huge economic losses in the event of a business failure. In general, private companies are organizations with challenging risk taking tendencies while public companies have a risk averse tendency to avoid risk, so these differences in organizational tendencies make it difficult to respond to risk. In particular, public companies are more likely to fail than private companies because they choose the contradiction of risk picking to enter overseas markets with high uncertainty despite their tendency to risk averse due to the nature of the organization. Therefore, these organizations need risk management techniques that reflect a risk-averse strategy. Accordingly, this paper analyzes the risk management research papers of the existing overseas development EPC business in order to find the risk management techniques related to the organizational tendencies of public companies and proposes "establishing a performance audit system for risk management of the organizational tendencies of public companies" as a way to extract the risk factors through the examples of overseas development projects of public companies and to manage the organizational tendencies of public companies that affect them.
