  • An infiltration technique using W-Cu composite powder has been developed to enhance microstructural uniformity of W-Cu pseudo-alloy. W-Cu composite powder, manufactured by reduction from $WO_3$ and CuO powder mixtures, were blended with W powder and then cold iso-statically pressed into a cylindrical bar under 150 MPa. The pressed samples were pre-sintered at $1300^{\circ}C$ for 1 hour under hydrogen to make a skeleton structure. This skeleton structure was more homogeneous than that formed by using W and Cu powder mixtures. The skeleton structures were infiltrated with Cu under hydrogen atmosphere. The infiltrated W-Cu pseudo-alloy showed homogeneous microstructure without Cu rich region

  • The defense IT master plan is the plan for promoting defense informatization and is established by the Ministry of National Defense every five years. In addition, an implementation plan has been established in accordance with the master plan every year to promote the informatization project. However, since there is no systematic methodology to check and analyze the master plan comprehensively, it is difficult to judge whether the goals suggested in the master plan are achieved, and continuous monitoring of the project is limited. This study proposes a concept and framework for defense IT investment management and proposes a methodology for examining and analyzing the progress of the defense IT plan by referring to the U.S. Department of Defense's IT Plan and the performance management structure of the national IT master plan. As a methodology for managing defense IT investment, we propose an IT investment management code system from the perspective of an IT portfolio and verify its applicability through case studies. The results of this study are expected to improve the defense IT performance management system and improve the efficiency and effectiveness of the defense IT project.

  • In order to protect the advancement of defense technology that has a tremendous e?ect on both the national security and the economy, the Republic of Korea established the Defense Technology Security Act in 2015. As the new enactment brought changes to the landscape of the defense industry and defense industrial security, a new examination of the concept of the defense industrial security has now become necessary. Even after taking into consideration the undisclosed nature of defense industrial security research, and the fact that only the limited number of firms participates in the subject matter, scientific studies related to the topic have not been active. However, with the new enactment of the Defense Technology Security Act, it is necessary to expand the scope of security and to redefine the concept of defense industrial security. In this paper, we analyzed the research works on related technology protection policies and our environment of the defense industry in order to conceptualize defense industrial security. The established concepts are expected to provide a systematic way to protect the confidential and defense technology.

  • Various security threats, such as North Korea's nuclear tests and intercontinental ballistic missile developments, are becoming issues. Considering the current security situation in South Korea, proper selection of weapons and efficient defense acquisition systems are essential. In this paper, we conduct a survey and analysis of the defense core technology necessary for the development of weapons systems, and review whether current defense research and development is carried out efficiently. A theoretical study was conducted on ways to enhance the linkage between defense core technology and weapons systems development. As a result of the study, the necessity for development of weapons systems and the linking of defense core technology planning with the need for institutional improvement in enhanced utilization of defense core technology were derived. We propose a method for a long-term weapons systems concept plan that integrates defense core technology planning with forces planning and pre-project research programs to improve planning efficiency.

  • 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.
