Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

The outflow of defense technology can cause serious damage not only in terms of business losses, but also in terms of national security and national interests. Recently, the government has enacted the Defense Technology Security Act, recognizing the importance of technology in the defense industry, and prepared guidelines for the defense technology security accordingly. According to the law, institutions and companies with defense technologies should establish a defense technology protection system, and the government should implement various technology protection policies to improve their level of technology protection. In this study, the implications were derived by comparing existing technology protection guidelines and priority analysis was performed on the protection system details through AHP for self-diagnosis items in the defense technology security guidelines. As a result, it is expected that it will enable efficient diagnosis of the level of protection and policy support for the systematic establishment of the protection system for the target institutions.

This study aimed to investigate flow of defense qi(衛氣) through the relationship among the collateral meridians(絡脈), Pyobon(標本), Kika(氣街) and Geungyul(根結). The nutrient qi(營氣) and defense qi have a same origin and are transformed from the food and drink(水穀), the nutrient qi flows in the meridian(經脈) and the defense qi flows outside of the meridian. The defense qi flows in the collateral meridians where meridians divide into smaller ones. The beginnig of the collateral meridian division is called Bon(本) and the finishing point is called Pyo(標). The defense qi flows from Pyo(標) to outside of the collateral meridian which is called Kika and then flows to skins(皮膚) and muscles (肌肉). The defense qi enters the meridian at Geun(根) and it joins the other qi within the meridian at Gyul(結). In this study, we suggest that the collateral meridian, Pyobon, Kika and Geungyul are continuos pathways where the defense qi circulates.

North Korea has steadily implemented defense reforms to strengthen its national defense capabilities, and in particular, has made military technology development and military industrial capability strengthening as the focus of national defense reform. North Korea's defense reform ultimately aimed at securing nuclear posture, and as technical achievements accumulated in the Kim Jung-Un era, it led to the development of military strength such as hydrogen bombs and ICBM/SLBM. Having secured nuclear capability, North Korea is also pursuing a symmetricality in the conventional military strength by securing a strategic advantage by pursuing the modernization of the conventional weapon systems through defense reform again. Up to now, North Korea's defense reform has succeeded in establishing a new ruling system for Kim Jung-Un and creating a driving force for negotiations with the United States.

Demand for performance analysis is increasing for efficient use of limited budgets such as improving investment efficiency and strategic budget allocation in accordance with the continuous increase demand of R&D budget for developing advanced weapon systems in the future battlefields. In accordance with the Act on the Performance Evaluation and Performance Management of the National R&D Projects established in March 2006, the performance analysis has been conducted for the systematic management and utilization of the R&D project performance. It was recognized as a project to achieve self-defense through strengthening the weapons system development capability, however, efficiency evaluation of Defense R&D projects was not much emphasized. Research on the efficiency analysis of defense R&D projects has been conducted in recent years, but most studies focused on corporate efficiency and productivity of defense companies. In this study, we analyzed the three-stage performance of defence R&D projects based on the logical model using the data envelope analysis(DEA) model. We also analyzed performance analysis from various perspectives through R&D type, technology classification and performance model. This study is expected to help defense department improve defense R&D projects and make decision.

The defense M&S system, which has been classified as a weapon system between requirements determination and project implementation, is being developed by applying the weapon system development procedure of the Defense Acquisition Program Administration. The M&S system abstracts and models the real world to suit the intended use and proceeds with the process of developing it as a software-oriented system. Overseas, the conceptual model development stage is staged before entering the design stage after the requirements analysis. In addition, each step includes verification and validation processes. In Korea, while establishing and applying the weapon system development procedure based on the SE process, the M&S system is also applied in the same way as the general weapon system, limiting appropriate development outputs and verification and validation. In this study, the system development procedure of the M&S system is established and presented based on the relevant standards and SE process of developed countries.
