Sense and Respond Logistics(SARL) is a transformational, network-centric, knowledge-driven concept that enables joint effects-based operations and provides precise, agile support. Sense and respond logistics relies upon highly adaptive, self-synchronizing, and dynamic physical and functional processes. It predicts, anticipates, and coordinates actions that provide competitive advantage across the full range of military operations. In this research paper, we considered the essential prerequisite to introduce the appropriate SARL concept for the future warfare environment into the military logistics support system and also provide the conceptual alternatives to actualize the introduction of SARL.

IPTV has been launched to provide a simple convergence service with broadcast and communication, and now it is evolving to support personalized service capabilities according to user's requirements. The paper presents DSON architecture and its control model to provide personalized features and user centric capability in IPTV services over service overlay network. Furthermore, the paper introduces DSON based service models on community IPTV and home IPTV service model.

The tactical data-link is useful to exchanging automatic information and controling command in combat environment. This is a essential factor of interoperability in the future combat situation of network centric warfare. In a aspect of a weapon system development, Modeling & Simulation can save expense. HLA RTI is a standard communication protocol in M&S. So, we suggest that Link Simulator connect tactical data-link through RTI. This simulator has the interoperability between M&S and tactical data-link, the reusability through adabing M&S framework, and the wide usability by automatic engagement function.

The principles of military operations(principles of war) are the fundamental principles ruling warfighting that made based on the experiences of wars from the time of ancient Greeks to the World War II. Recent wars such as Iraq War showed us the change of environment of war and the style of waging a war. It is believed that future war will be executed with the style of Rapid Deceive Operations, Effect Based Operations, Network Centric Operations. Therefor the principles of war which we use should be reconsidered whether it is useful or not in future warfare. By considering the present principles of operation which are using in many countries and analysing the style of waging future war, we suggest new principles of operations : principle of gravity, principle of mass and dispersal, principle of disturbance, principle of speed, principle of paralysis, principle of synchronization and integration, principle of leadership, and principle of information.

This study explored the ridership pattern between Seoul and Busan after the introduction of KTX in 2004. Since the KTX opening, average daily passengers on the Kyungbu lines have increased. These figures clearly indicate that the transportation network is becoming railroad-centric. However, the operation. of the KTX will leave many existing Saemaul and Mugunghwa train sets idle, which will be put into operation for areas, not covered by the KTX. Statistics show that the railroad ridership is clarified the distinction between train service levels. So, our paper studied the change of market share by service levels between Seoul-Busan line which is a long distance route.

Recently, due to the rapid development of the internet, the production and demand of high capacity contents are rapidly increasing. In order to accommodate the changing trend of internet usage, researches on CCN, the future internet architecture, are actively being conducted. Mobility support is an important challenge in CCN real-time services, given that today's internet environment is changing to mobile and real-time services are increasing. In CCN real-time services, the mobility problem can be largely divided into consumer mobility, provider mobility, and intermediate-node mobility. Among them, when the intermediate-node moves in the CCN real-time services, the service disconnection occurs and the QoS degradation is caused. In this paper. we propose Intermediate-Node Mobility Support(INMS) to support the intermediate-node mobility in CCN real-time services. Experimental results show that the proposed scheme shows better performance than CCN in terms of service disconnection time and packet loss.

Unmanned surface vehicles(USVs) have been developed for special operations in foreign navies. These will be employed to conduct critical missions including inspection, coast guard, ISR, fire protection, precision strike, mine interception warfare and antisubmarine warfare. It is also known the USVs will be deployed at the front line of the network-centric warfare to replace the manned naval operations. The unmanned operation can, thus, minimize unnecessary risk to personnel and enhance the success probability for the imposed mission. In this research, the USVs which are under operation and development in foreign navies are investigated. Based on this, an USV with $7\~10m$ of length and 10ton of weight for the Korean Navy which can be deployed near the Northern Limit Line(NLL), is proposed.

The vetronics is necessarily required for enhancement of the operational capability and optimization of the system architecture. In this paper, we presents the realtime control methods for the vetronics of the fighting vehicles. We proposed the data distribution based on standard bus and computer resource for realtime and integrated control of the system. Embedded computers are designed considering extensibility and reliability of the system. The integrated display improves the operator's capability. We applied the network centric battle management and digital power control with intelligent switching elements to increase cooperated combat efficiency and reliability. To show the feasibility of the presented design schemes, the vetronics has been implemented and applied to a real fighting vehicle.

비디오 데이터는 인코딩 단계의 특성상 패킷 드롭과 네트워크 딜레이에 무척 민감하다. 그렇기 때문에 레이트 컨트롤을 통해 대역폭이 변화하는 네트워크 환경에 대응 하고자 하는 연구가 진행 되어왔다. 하지만 컨텐츠 중심의 네트워크 환경에서는 소스 노드 뿐만 아니라 중계 노드들 또한 데이터를 전송함으로써 레이트 컨트롤을 위해 소스 노드에 접근 하는 것은 컨텐츠 중심의 네트워크의 장점을 상쇄 시킨다. 이 문제를 해결 하기 위해 계층별 비디오 컨텐츠 정보를 활용한 중계 노드 에서의 패킷 스케줄링 모델을 제안한다. 이로써 컨텐츠 중심의 네트워크에서의 사용자 네트워크 환경에 적응적으로 동작하는 효율적인 비디오 스트리밍이 가능하다.

지금까지 발표된 상호운용성 측정모델은 점대점(Point-to-Point)으로 단위시스템간 상호운용성을 평가하는 모델부터 네트워크중심(Network-Centric)의 복합시스템(System of Systems)간 상호운용성을 평가하는 모델까지 여러 모델들이 있다. 그중 SCOPE 모델은 네트워크중심의 복합시스템간 상호운용성을 평가하기 위한 모델이고, NCAT은 SCOPE기반의 상호운용성 평가 도구이다. 본 논문은 SCOPE를 기반으로 NCAT의 상호운용성 평가 방법과 다른 상호운용성 평가 방법론을 제시한다. 제시된 방법론은 SCOPE 모델을 기반으로 복합시스템의 상호운용성을 평가 할 때 서비스별 우선순위를 부여하지 않은 기존 방법과 달리 우선순위를 부여한 방법이다.
