CCTV network has been implemented to transmit the image information of platform, ticket gate and transfer section to local headquarters in the KNR(Korean National Railroad). But, communication system for transferring image information around accident field or wayside has not been established ret. thus, at Present implementation of communication equipment is necessary for dynamic image of unspecified accident to be transmitted to headquarters. Copper cable communication network is run by KNR, but it is processing installation of optical cable in connection with the implemental plan for high-speed network from now on. And, the capacity of communication channel will be guaranteed much more than now between station and station. station and central headquarters when optical cable is completed. This study analyzes the image equipment of field for transmission and estimated matters to transmit image information of accident field to headquarters with using communication infrastructure. And, the study considers implemental method of communication network for long-distance image transmission from dozens to hundreds kilometers.

For the office work environmental design, the importance of the design management is increased to improve operation efficiency as well as the aesthetic environmental implementation of the function today. Lighting is a required element ineffective operation environment. It has become more important for the aesthetic, economic, and practical reasons, to consider the luminous environment and the lighting of visual tasks separately. When the brightness is insufficient, productivity deteriorates, and the layout of the lighting located by mistake causes the fatigue of eyes. Productivity rises to office in a large number of studies so as satisfaction is low in general in the dark office, and to be bright. Therefore the purpose of this research is to suggest the right direction of lighting design of office building area. 11newly renovated office buildings are selected for this luminous environment research. We could conclusions as following through this research. First, it was planned brighter than the recommended lighting level in the most space. It shows that the accurate lighting design criteria is needed in order to achieve proper lighting environment. Second, the application of the LED lighting fixtures is continuously increased in the recent office lighting environment. It is explained that it is applied for reasons of the electrical energy reduction and the maintenance efficiency with the long life time. Third, the consideration of the lighting plan for the difference of working types is not enough. with various communication configuration through an independent plan, and the effective lighting plan that appropriateness preparation design and energy saving area vailable must be applied. Fourth, the lighting environment of the lobby needs a specialized lighting plan as are presentative space of the building.

최근 건설 프로젝트의 효율적인 관리를 위해 현장에서 각 사업주체(발주, 설계, 감리, 시공, 협력업체)간 원활한 의사소통, 협업, 정보공유 및 교환을 위하여 사업관리시스템인 PMIS(Project Management Information System)를 많이 사용하고 있다. 그러나 이러한 개별 프로젝트단위로의 시스템 개발은 회사 전체 프로젝트관리 효율성 및 통합화에 저해요인으로 지적되고 있다. 이는 프로젝트단위로 개발되는 사업관리시스템의 특성상 전사차원의 시스템개발 및 보급을 위한 Master Plan인 ISP(Information Strategy Plan) 즉 정보화 전략의 수립의 부재에 기인한다고 볼 수 있다. 본 논문은 실제 대형 건설회사인 국내 D건설사의 PMIS구축을 위한 정보화전략계획(ISP) 수립방법 및 절차의 사례를 소개하고 전사 PMIS구조, 전사업무프로세스 개선과 시스템 구축방법 및 성공요소 등을 제시한 논문이다. 이 연구 논문을 통해 향후 건설회사의 사업관리 시스템 구축 시 효율적인 PMIS개발과 최적화시스템을 구축에 도움이 되고 정보화 전략계획 수립에 활용 할 수 있기를 기대한다.

위성통신 중계기의 한정된 자원 (대역/전력 등)의 사용 효율올 극대화하기 위하여는 위성통신 시스템간 또는 시스템 내에서 발생하는 동일채널간섭 효과를 최소화하도록 서비스를 할당하는 것이 바람직하다. 본 논문에서는 위성통신 서비스별 증계기 할당 목적에 최적이라 생각되는 cost 설정 방법을 제안하고 시뮬레이션을 통하여 제안한 방식의 효율성을 보였다. 서비스 할당문제 자체보다는, 특히 서비스 할당을 위한 cost 설정문제 (BER 성능을 최적화하는 기준의 cost 선정 방식)에 국한하여 cost 설정을 위한조건 및 이를 만족하는 cost 함수에 대해 연구하였다. 제안한 cost 설정 방식은 위성통신 서비스의 할당문제에 매우 효과적으로 적용될 수 있을 것이다.

This study is for Hanbuk Mountain Range within Gyeonggi province which is to propose the conservation plan by each damage pattern through site survey of the mountain range. The damage patterns are classified by siding, pointing and lining. The total damaged area is 103 areas: The siding pattern is damaged by developing farmland, mineral and quarry mining, dam, large scale development complex and cemetery park; The pointing pattern is including the development of road, transmission tower and way and mountaineering trail; The construction of electricity and communication facility, military facility, mobile communication station, heliport and shelter. The damages by developing road and large scale development complex are the most cause, and military facility, dam and reservoir, and residential area are the main causes, respectively. One of the compromised situation Hanbuk-Mountain Range usage as per section 7 section (18.45%), 12 section (18.45%) is the largest number of compromised has been surveyed, undermine the situation if you look at the usage by the road 25 locations (24.22%), military facilities and dam and reservoir to undermine this 11 established respectively (10.68%) were the most undermine. Therefore, this research propose the conservation plan as follow: first, need to understand, educate and publicize on Hanbuk-Mounatin Range; second, manage through the regulations and ordinance of Gyeonggi province; third build and expand the law for protecting Baekdu-Great Mountain Range.

To keep pace with other powerful nations in this era of the era of digitalization and to emerge stronger in the world, the defense forces of South Korea aim to innovate and prepare themselves for digital battlefields of possible wars in the future. The resources in the defense sector, which is the core of defense intelligence, is based on an intelligent mission collaboration tactical network system via cyber, command, control, communication, and computer (C4), and military and non-human weapons. Defense intelligence depends on the degree of the convergence of advanced Information and communication technologies (ICTs). Considering this aspect of defense intelligence, We plan to determine the application status of defense blockchain technology and examine the feasibility of applying blockchain technology and the core of applied technology. Generally, a key feature of blockchain technology is its data integrity in untrusted environments. There are various types of core technologies for the blockchain depending on the target areas of application in the defense sector, and it is also essential to derive new application strategies for core technologies that are applied in combination with other ICT technologies. We plan to demonstrate new defense ICT converged technologies (DNAB2: Data, Network, AI, BigData, Blockchain) and DNAB2-As-Services in the defense strategy.
