In this study, a nondestructive test (NDT) is performed to inspect the optimal design of a ground tracked combat vehicle for self-propelled artillery, tank, and armored vehicles. The minimum qualification required for personnel performing the NDT of a ground tracked combat vehicle was initially established in US military standards, and then applied to the Korean defense specifications to develop a ground tracked combat vehicle. However, the qualification standards of an NDT inspector have been integrated into NAS410 through the military and commercial specifications unification project that were applied in the existing aerospace/defense industry public standard. The design method for this study was verified by applying the optimal design to the liquid penetrant testing Al forging used in self-propelled artillery. This confirmed the reliability and soundness of the product.

Unmanned Autonomous Vehicle's driving road in the national defense includes not only paved roads, but also unpaved roads which have rough and unexpected changes. This Unmanned Autonomous Vehicles monitor and recon rugged or remote areas, and defend own position, they frequently encounter environments roads of various and unpredictable. Thus, they need additional learning to drive in this environment, we propose a Additional Learning Nearest Neighbor (ALNN) which is modified from Approximate Nearest Neighbor to allow for quick learning while avoiding the 'Forgetting' problem. In addition, since the Execution speed of the ALNN algorithm decreases as the learning data accumulates, we also propose a solution to this problem using GPU parallel processing based on OpenGL Shader Language. The ALNN based on GPU algorithm can be used in the field of national defense and other similar fields, which require frequent and quick application of additional learning in real-time without affecting the existing learning data.

Software-Defined Networking (SDN), which has emerged to overcome the limitations of existing network architectures, makes routing management simpler and more efficient through a central controller. SR (Segment Routing) is a flexible and scalable way of doing source routing, and defines the information path of the network through a list of segments arranged in the packet header. In an SDN environment, the performance of each router is almost the same, but packets tend to be concentrated on routes that are frequently used depending on routing algorithms. Routers in that path have a relatively high frequency of failure and are more likely to become bottlenecks. In this paper, we propose a routing algorithm that allows the router, which is a resource in the network, to evenly process packets in the SDN with SR, so that the administrator can utilize the resources in the network without idle routers, and at the same time facilitate the management of the router.

Energy Security has been factor of great importance to national security, economy, society and all other areas. However, it has been in the lack of situation where there is no leading method to measure energy security nor to compare among countries until now. In the research, objective index to assess energy security has been developed and compared among the level of countries in terms of energy importing countries' perspective. Based on the suggested index, comparison for the energy security level has been explained. The implication of the research is that in terms of energy importing perspectives, method to appraise energy security and according to this, energy security rate by each countries with respect to LNG. This method is doubtlessly applicable to comparison of security rate from other resources and fluctuation of energy security by reflecting other factors. Also, discussion about how increased autonomy of resources can impact Korean energy security with regard to recent international energy development. As a consequence, it has revealed that enhanced authority of resources evokes ascendancy of energy security in a positive way.

Theorists of war have often used Clausewitz's trinity theory as a framework for analyzing war strategies and histories. Heretofore, studies on cyber warfare have focused primarily on laws, policies, structuring organizations, manpower, and training pertaining to preparing the cyberspace for war. Currently, studies highlighting the comparative characteristics of war in cyberspace, how it differs from conventional warfare, and analytical frameworks for understanding war in cyberspace are rare. Using Clausewitz's trinity theory, this paper interprets the essence of war from the perspectives of (1) Intellect, (2) Bravery, and (3) Passion, to propose an analytical model for understanding war in cyberspace, one that factors in the intrinsic qualities and characteristics of cyberspace under spatial and temporal constraints. Furthermore, this paper applies the aforementioned analytical model to the Iraq War and concludes with a theoretical illustration that cyber warfare played a significant role in winning the war.
