현재 재난정보전달시스템은 재난 유형별, 유관기관(중앙부처, 지자체) 별로 독립적으로 운영되고 있어, 해당 시스템 간 연계가 미흡하여 통합적인 재난정보 확보와 적절한 조기 대응이 어렵다. 이를 해결하기 위해 예·경보 플랫폼과 상황전파 플랫폼 간 연계할 수 있는 통합 재난안전정보체계 및 통합플랫폼 개발이 필요한 실정이다. 또한, 재난 대응을 위해 전달되는 정보의 형태 및 전달되는 매체는 제한적이므로, 신속 정확하고 다양한 재난 정보 전달을 위해서는 새로운 방송 및 통신기술을 활용하여 멀티미디어 기반 재난정보 전달을 위한 표준 제정 및 시스템 고도화가 요구된다. 본 논문에서는 차세대 ICT 기술과 멀티미디어를 지원하는 재난정보전달플랫폼에 대한 기술개발을 통해 기존 구축되어 있는 재난안전정보공유플랫폼 및 관련 재난안전정보시스템과 연계 가능하고 표준화된 다매체 기반의 멀티미디어 재난정보전달플랫폼을 개발함에 있어 차세대 통합 예·경보 플랫폼을 위한 통합관제시스템에 관한 연구를 진행한다. 이는, 대국민을 대상으로 신속하고 안정적인 재난정보 전달을 실현하고 대관(재난관리기관)에 대한 재난현장정보 수집의 어려움 해소 및 현장 중심의 양방향 의사전달을 증대하여 다양하고 정확한 멀티미디어 재난정보전달을 수행한다.

Launch Control System(LCS) performs the pre-launch preparation and launch operation during launch campaign. The successful launch operation is basically influenced by hardware and software of LCS. Especially, a trivial errors in control algorithm can cause critical problem or disaster in launch operation. Therefore, the hidden or implicit errors should be distinguished and eliminated by the verification test in advance. In this paper, the design and implementation of hardware and software simulator which have already been used in LCS verification will be introduced. By presenting the detailed design and flowchart-based algorithms, we make other similar systems adopt the implementation philosophies of this paper. Especially, this paper emphasizes that all the simulation algorithms work on the self-controller in LCS without using separated computer or PLC.

Currently many central administrative agencies, municipalities and public and private institutions operate Managed security services to cope with cyber security incidents. These entities exert efforts in operating efficiencies rather than introduction of services as they used to. Accordingly, quite a few policies, directions and guidelines have been established for stable operation of Managed security services. Still, Managed security is operated by individuals, whose competencies influence the quality of Managed security services to a great extent. In this respect, the present article examines Managed security technology and methods and describes evaluation methods and examples relevant to human competencies, so as to seek for some potential courses for further development as well as more efficient approaches to human resource management in terms of institutional Managed security services.

최근의 국가 민간의 정보시스템을 위협하는 공격들은 점점 더 복잡해지고 정교해지고 있다. 이러한 공격들에 대응하기 위하여 범국가적으로 사이버안전센터들이 설립 운영되고 있다. 그러나 이러한 대량의 정보보호 데이터를 수집 분석 대응하는 것은 여러 가지 어려움들이 존재한다. 그 문제의 본질적인 부분은 바로 방대한 데이터의 양(量)이다. 다수의 보안관제 대상 인프라들의 모든 보안데이터를 수집 하는 것은 사실상 불가능하며, 대부분의 센터들은 네트워크 접점에 중앙관리형 보안인프라를 설치함으로써 그 해결점을 찾고 있지만, 이는 최근의 나타나고 있는 다차원적인 공격에 대응하기에는 한계가 있다. 본 논문에서는 이러한 다차원 분석시스템의 기본데이터가 되는 여러 보안정보를 효과적으로 수집할 수 있는 보안정보 수집체계를 제시하고자 한다.

Korea is surrounded on three sides by the sea, through the maritime transportation accounts for close to 90% share in the total cargo volume. In addition, there are amount of small and medium-sized fishing vessels registered. These days, a number of maritime accidents caused many casualties and having an adverse effect on the marine environment. Therefore, there is a need for a maritime traffic control has been increasing. Information about the ship is divided into AIS information for VTS, Port Management Information System (Port-MIS) operated by the Port and vessels pass (VPASS) that are installed on fishing. However, there is a problem that is not achieved the information exchanged between each other. That is, information on the vessel are stored in diverse inefficient in the management, operation and utilization. This paper discusses the ways to efficiently manage and integrate vessels information for VTS, and proposes the method for implementation and application.

This paper relates to the study about the street security light management system. The purpose of the wireless remote management system is to manage street security lights efficiently. The system is composed of three components like light controller, CDMA gateway and web based remote management server. The zigbee solution is adopted to make local wireless network between street security lights. The CDMA network is used for the wireless communication between street security light controller and the remote control center. The gateway to interconnect zigbee network and CDMA was designed with low power 32 bits Cortex M3 micro-controller. For the data communication between the management server and the gateway, SMS and socket based TCP streaming is used. The management server sends SMS to the gateway to deliver light control and management requests, and the gateway replies with the light controllers report via TCP streaming. By using both SMS and TCP streaming communication, it was verified that simple cost effective management is possible for street security lights. We tried real test for 95 street security lights in real environment during two months and analyzed the practical possibility for mass supply.
