This study derives essential information elements that should be shared in the situation board by utilizing the concept of common operating picture (COP). The COP's concept and actual overseas cases were confirmed, and COP information elements that should be considered for disaster situations were redefined. The COP disaster response information elements were derived by analyzing the standard manual for disaster response and daily situation reports issued in Korea. The information elements were divided into four stages (①Report reception and recognition stages, ②Situation propagation and reporting stages, ③Emergency equipment operation stages, ④Recovery and recovery stages), centered on storm and flood damage. Further analysis of the detailed information elements was conducted to derive the information elements that must be shared in the context board. The information is shared along with spatial and geographical characteristics due to the characteristics of the COP, providing complex information to decisionmakers and officials, enabling diverse access to disaster situations. Furthermore, it is expected that disaster response will be more efficient by sharing the information in common.

2016년 경주지진, 2018년 밀양 세종병원 화재사고, 2019년 강원도 동해안 산불, 2020년 코로나바이러스감염증-19 재난까지 매년 다양한 유형의 재난이 발생하면서 재난대응에 대한 관심 역시 커지고 있다. 정부는 물론 각 지자체에서 재난유형별로 재난대응 매뉴얼에 따라 체계적으로 해당 재난에 대한 대응을 실시하고 있으나 중앙 상황실과 현장 간 소통의 어려움, 의사결정의 지연 등으로 인해 신속한 대응방안 수립 및 피해상황 파악에 있어서 미흡한 대처를 보여주어 질타를 받기도 하였다. 본 연구에서는 중앙 상황실과 현장 간의 원활한 소통과 재난으로 발생한 피해현황 및 응급복구 계획 등을 신속하게 수립할 수 있도록 군부대에서 사용하고 있는 공통작전상황도(Common Operating Picture, 이하 COP)의 개념을 재난대응 체계에 도입하여 제시하고자 한다. 공통작전상황도는 미군이 군사적인 대응을 위하여 정보공유 차원에서 처음으로 사용되었으며, 미국연방재난관리청(Federal Emergency Management Agency, 이하 FEMA)이 현재 재난상활 발생 시 의사결정을 지원하기 위한 시스템으로 개발하여 활용하고 있다. 이를 구성하는 요소들은 재난발생시 가장 기초적인 정보(신고사항, 기상정보, 시민제보 등) 뿐 만 아니라 현장에 관한 정보(구체적인 대응상황, 요구사항 등)까지 다루어지고 있으며, 결국 공통작전상황도는 이를 모두 관리할 수 있는 하나의 통합플랫폼이라 할 수 있다. 따라서 본 연구에서는 재난상황에서 공통작전상황도를 활용한 해외사례 분석과 국내 도입 시각 재난유형별로 공통작전상황도에 필요한 정보요소들을 1차적으로 확인함으로써 새로운 재난대응 시스템의 필요함을 강조하고자 한다.

As technology evolves, Internet usage continues to grow, resulting in a geometric increase in network traffic and communication volumes. The network path selection process, which is one of the core elements of the Internet, is becoming more complex and advanced as a result, and it is important to effectively manage and analyze it, and there is a need for a representation and visualization method that can be intuitively understood. To this end, this study designs a framework that analyzes network data using BGP, a network path selection method, and applies it to the cyber common operating picture for situational awareness. After that, we analyze the visualization elements required to visualize the information and conduct an experiment to implement a simple visualization. Based on the data collected and preprocessed in the experiment, the visualization screens implemented help commanders or security personnel to effectively understand the network situation and take command and control.

It is very important for more effective military operation to share information required in recognizing a situation by monitoring battlefield. The recognition of situations is offered visually though multi-media systems such as a COP(Common Operation Picture), UAV etc. The operating method has rapidly changed into Network-Centric Warfare (NCW). As a result, the data that these Multimedia systems should control is increasing. Improved performance of Multimedia systems is required to deal with them. In this paper, we propose Extended-Military Multimedia System(E-MMS) applying the most excellent scheduling method in terms of meet-ratio in real time when Multimedia systems carry out assigned information in real time for monitoring as the method of improved performance. As a result of utility about proposed system, it is verified that realtime EDF(Earliest Deadline First) scheduling method is more improved up to 20% compared to non-realtime FCFS(First Come First Service) in terms of the deadline meet ratio.
