This study focused on service quality, service value, service satisfaction and service trust of system being used in DAPA(Defence Aquisition Program Adminstration) to manage logistic items. DAPA in operating a few systems to manage efficiently logistic items. This study focused on the catalog management system service quality. Because catalog management system has been the most requested service system of being used in DAPA by defense firms since DAPA was founded, it would be the most fitted system in this study. Through this study, we drew a direction in establishing service. This study also could be applied to business practice so defence industry firms would trust DAPA and DAPA could offer a better service quality. Quick and exact service offered by logistic catalog management system would lead delivery of military supplies and export. Consequently, the best quality service would contribute to profit increase for defence industry firms, independent defence and nation economy development.

The Korean defence industry has grown rapidly since the 1970s. In 2015, it generated more than 168 billion won in economic revenue, and exports exceeded 3.6 billion won. With the development of the defense industry, the level of the quality management system for major contractors has improved substantially, but there are many areas of the quality management system that still need improvement for small subcontractors. Therefore, in this paper, we develop a methodology to improve the quality management system for small subcontractors. Based on 101 collected cases, this methodology results in generally improved effects and generally improved methods. By applying the Russian Theory of Inventive Problem Solving (TRIZ) concept of a contradiction matrix, three improvement matrices are derived. A developed improvement matrix is the main support tool of this methodology. This methodology consists of four tasks and eight subtasks, and it can be used as a support tool for creative problem solving by the quality assurance department and the quality assurance manager for small subcontractors.

The defense industry has become a global industry, and military technology is actively being traded between countries to increase their military capabilities. The Republic of Korea has been ranked one of the top 10 countries for exports of military technology. To maintain competitive advantages in the global defense industry, it is essential to protect key technologies employed by exported weapon systems. Various techniques have been developed for protection of confidential technologies in weapon systems, and the U.S. DoD has been leading the development of the protection techniques. This paper reviews current anti-tampering techniques that prevent leakage of key technology from weapon exportation or pillage. Based on the protection techniques employed by the U.S. DoD Anti-Tamper Executive Agent, this paper suggests novel design methods for protection of confidential technologies. The proposed design methods were tested on an actual weapon system.

The current methods, such as Binomial Probability Distribution or T-test, to calculate the number of samples of Precise Guided Missiles(PGMs) for test and evaluation are statistically problematic to make reasonable decisions thus use the budget efficiently. Also, the method to verify an accuracy rate of the PGMs using these old methods seems to be lack of objectiveness. This paper presents an effective, efficient solution adapted from the clinical medicine testing method of healthcare industry research, which may overcome our problems. This method considers and addresses both manufacturers' and consumers' risk simultaneously. By taking into account the weapon system project characteristics which take a relatively longer time and require higher-level budget, this approach also suggests a reasonable and feasible method to determine the amount of samples of the PGMs and making a criterion to verify an accuracy rate of the missiles that are required to test. Thus, this method is expected to contribute to acquisition and operations of high-reliability PGMs by MND and its field-users.

스위스 국방부의 DTPA(Defence Technology and Procurement Agency)에서 건설한 대구경 실내 사격장 (P.59 사진)의 규모나 완벽함에 감탄하였으며 좀더 자세한 기술조사가 필요하다고 느꼈고, 스위스와 같은 평화를 사랑하는 중립국가에서 조차도 이러한 무기개발에 필요한 실험시설을 위해 막대한 투자를 하고 있구나라는 생각이 들었다.

For design optimization, engineers should require the accurate information of design space and then explore the design space and carry out optimization. Recently, the total design framework, based on design of experiments and optimization, is widely used in industry areas to explore the design space above all. For optimizing turbofan engine design point, the response surface model is constructed by using the 7 level orthogonal array which satisfies the statistical uniformity and orthogonality and gets the dense design space information. The multi-objective genetic algorithm is used to find the optimal solution within the given constraints for finding global optimal one in response surface model. The optimal solution from response surface model is verified with GasTurb simulation result.

This study examines the relationship of the industry-specific factors that effect innovation of manufacturing technology and the market share within the defense industry. Since the establishment of the basic defense industry framework in 1973, there were numerous interactions of the industry-specific factors of the defense industry structure with the technological innovation and market organization of the defense industry. During last three decades, the domestic defense industry has achieved the considerable level but the framework of the basic system has not developed much in areas of the military science and the defense manufacturing technology. Industry-specific factors were formed in the process and appeared in a variety of behavioral characteristics as subsystems. Currently, there IS a growing trend where the management of defense industry is gradually deteriorating due to limitation of the domestic industry-specific factor (e.g. defense technologies, amount of demand, etc.). If there is a prominent imbalance of the industry-specific factors. it can trigger the potential problem of conflict, lack of cooperation and control, slowing the growth of the manufacturing technology thereby diminishing the market and deteriorating the defense supply/demand relationship. In a research conducted by Joe S. Bain, Bain analyzed the relationship of the traditional industrial organization where industry-specific factor(S) not only impacts the conductor(C). And, conductor(C) influences the shaping of the performance(P) of relationship of the traditional industrial organization. Consequently, the researcher has identified the demand monopoly, barriers to entry, and market competition with comparison of defense industry issues. These defense issues were three industry-specific factors identified, which are 1) The demand monopoly and The entry barriers to new market competition, 2) the industrial technical factor to a production technical competitiveness and a market sharing competitiveness, 3) the probability factor to revolution for military affairs(RMA) and a R&D production. According to baseline with these factors, the following research model is established from the special companies group(Group A), the systematization companies group(Group B), and the general companies group(Group 0. The hypothesis is that if there are more industry-specific factors, then there will be more relationships of defense industry relation statutes. This research is an empirical study on the relationship that the industry specific factors effects the innovation of manufacturing technology and the shaping of the market in the defense industry. Moreover, the existing models to evaluate the industry specific factors of the defense industry IS much to be desired with the controlled statistical analysis of the result. It is vital to study on current situation with suggesting alternative strategy to the efficient strategy. The descriptive analysis approach analysis is conducted with SPSSWIN to conduct reliability test, factor analysis, correlation analysis, cross-tabulation analysis, one-way ANOVA, and multiple regression analysis. However, there were some limitations of the survey such as the rigidity of concept about the technical factors and various market management factors. The wishes is that the decision-maker could be utilized these defence industrial factors to formulate efficient defence policy and strategy in the future.
