DIFs (Data Interchange Formats) are needed to enhance interoperability of physically distributed organizations in SBA (Simulation Based Acquisition) process. DIFs play a role as a template of DPDs (Distributed Product Descriptions) and provide capability to use information directly without data format interchange process by allowing access to DPDs, which include various information and M&S (Modeling & Simulation) resources. This characteristic is essential for interoperability in ICE (Integrated Collaborative Environment) based SBA. This paper proposes a framework for the DIF and outputs from each phase of acquisition process for configuration data related to design and manufacturing in SBA process - Conceptual Data Model, Logical Data Model, Physical Data Model and Physical DIF based on XML. Finally, we propose the DIF model architecture and demonstrate the implementation of DIF example based on it.

The DoD of United State, the MoD of United Kingdom and NATO have developed and implemented not only the concepts of joint capability but also management system for the joint capability to respond the future uncertain operations effectively. The resources of the DoD in United State have been efficiently planning, programming, budgeting, execution and evaluation using the PPBEE system which developed based on the concept of joint capability. The joint capability of the DoD has been managing through the JCAMS (Joint Capability Area Management System) which constructed based on JCA, UJTL and so on. Recently the MND of Korea eager to try introducing concept of the JCMS and developing the JCMS like the JCAMS of DoD for the future joint operation in the uncertain environment. We propose the holistic mechanism to develop the JCMS (Joint Capability Management System) of MND which can implement during the constructing the JCMS of Korea efficiently and effectively.

This study is based on the information security management system, the threat from mobile office, mobile office configuration item type, vulnerability analysis and control at the level of the current possibilities for technology to its purpose. To perform exploratory study for mobile Office to target the new technology, we were used the integrated research methods such as the documentary survey, expert FGI and real user's survey. To identify the main risk areas of mobile office services, we develop the mobile service layer model that separated the place, terminal, network, server according to service deliverly system. Finally, the result of survey for threats and vulnerabilities showed that the control of the terminal of user is a significant.

We already have seen many studies and articles about the methodology responding the security risks and threats. But we still have some controversial subjects to be settled. Now, we are living in the era that we should focus on how to use the security systems instead of how to make it. In this point of view, a company need to find out the answer for these questions, which security risks have to be handled in a corporate, which system is better for responding the security threats, and how we can build necessary security architecture in case of developing systems. In this article, we'd like to study on-site scenarios threatening the corporate assets, the limit on dealing with these threats, and how to consolidate the security events and information from enormous assets. Also, we'd like to search for the direction form the actual cases which have shown the desired effect from converging the assets and network informations.

Since 1993, Successfully localized naval combat System has made steady development on various domestic and foreign ships. On the other hand, Engineering Control System(ECS) is dependent on foreign companies. Therefore, there is a lot of interest and research in the localization of ECS in the navy defense industry. As one of various studies, a preliminary study of domestic ECS software that can be commonly applied to naval ships is in progress. This paper propose Ecs Obts Scalable Platform(EOSPA) as the standard architecture of ECS On-Board Training System(OBTS) software by applying object-oriented programming and standardization. And this introduces EOSPA's structure, function, and features of each component. Furthermore, high reusability and maintainability are expected in the development of ECS OBTS software applying EOSPA in various naval ships.

The architecture named IDPS is a design concept of web-based integrated platform for heterogeneous naval combat system, which accomplishes efficiency(decreasing complexity) of diagnosis process and reduces time to diagnose system. Each type of surface vessel has its own diagnostic processes and applications, and that means it also requires its own diagnostic engineer(inefficiency in human resource management). In addition, man-based diagnostic causes quality issues such as difference approach of log analysis in accordance with engineer skills. Thus In this paper, we designed integrated diagnostic platform named IDPS with simplified common process regardless of type of surface vessel and we reinforced IDPS with status decision algorithm(SDA) that judges current software status of vessel based on gathered lots of logs. It will enable engineers to diagnose system more efficiently and to use more resources in utilizing SDA-analyzed diagnostic results.

In this paper, we propose an efficient network virtualization model in cloud computing environments. Virtualization is a key technology for the implementation of service-oriented architecture. It is a standardized framework that can be reused or integrated with changing business priorities through a IT infrastructure. Network virtualization has emerged as an important technical issues of the future virtualization technology in Internet. The concept of network virtualization and related technologies stay in ambiguous status since network virtualization is in its early stage. Thus, we propose a network virtualization model for cloud environment by analyzing the existing network virtualization technologies.

In domestic island regions, the power supply generally depends on diesel generators due to difficulties of grid connection. To solve this issue, recently, the study on the stand-alone microgrid technology and its test are being actively conducted. In this paper, we propose the stand-alone microgrid integration monitoring system for energy independence island. First, we design the software architecture for monitoring of solar, wind, diesel power generation facilities, transmission and distribution of grid network, and energy storage system. Then, we implement the monitoring software that allows administrators to identify and run the monitoring software easily.
