방위산업기술 보호에 대한 중요성이 강조되면서 국내에서도 방위산업기술 보호법을 2015년에 제정하여 시행하고 있다. 방산기술 보호법 제7조에 의하면 대상 기관은 해당 기관이 보유하고 있는 기술의 방위산업기술 해당 여부 판정을 위해 방위사업청장에게 신청할 수 있고, 방위사업청장은 기술검토를 통해 판정하고 결과를 신청인에게 서면으로 알려야 한다. 하지만 법 시행 초기로 판정을 위한 세부적인 절차 및 기준이 규정화되어 있지 않아 판정결과의 객관성이 저하될 소지가 있다. 따라서 방위산업기술 판정 특성과 우리나라 실정에 맞는 절차마련이 필요하다. 본 연구에서는 국내외 기술보호 규정 및 사례 분석을 통해 방위산업기술 판정에 적용될 수 있는 기술검토 절차를 제시하였다. 기술검토 절차는 판정대상 기본검토, 기술특성 검토, 종합검토의 3단계로 구성된다. 특히 기술특성 검토를 위한 평가항목에 대해서는 델파이 설문을 통해 중요도를 분석하여 7개 항목을 도출하였고, 이를 통해 항목에 대한 당위성을 확보하였다. 본 연구의 결과로 방위산업기술 판정의 일관성 유지 및 객관성을 향상할 수 있으며, 방위산업기술 판정 기술검토 절차를 규정화하는데 기초자료로 활용될 수 있을 것으로 기대한다.

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.

In the telecommunication industry, estimation of the cost of network facilities is very important since depreciation cost of the facilities accounts for a large portion of the product cost. Moreover, cost estimation in the industry becomes more difficult because of increasing indirect cost upon digital convergence, expanding multi-purpose facilities, complexity of service product, etc. Nevertheless, not much seem to have been done in improving estimation methodology of the cost of network facilities. As a result, the quality of cost information on network facilities has deteriorated, and now even decision-makers in the industry dismiss the information. Recently, two major telecommunication companies adopted a new network cost estimation method to deal with the issue. In this paper, we study the concept of new cost estimation method and the procedure to develop and apply it. We also suggest the method to carry out the cost allocation using Matlab which is more efficient and time-saving than other commercial cost calculation packages.

The acquisition cost of defense weapon system has been continuously increasing because of art-of-technology of it. This phenomenon requires efficiency and transparency in the weapon system acquisition process through cost estimation. Therefore cost estimation is very important to the government acquisition programs to support decisions about funding and to evaluate resource requirement as a key decision point. The Commercial parametric cost estimating models have been using extensively to obtain appropriate cost estimates in early acquisition phase. These models have many restrictions to ensure the cost estimating result in Korean defense environment because they are developed based on foreign R&D data. Also estimation results are different from Korean defense industry accounting system. So, some studies have been tried to develop a CER (Cost Estimation Relationship) based on the Korean historical data. However, there are some restrictions to improve the predictability and ensure the stability of the developed singular CERs which consider the following data characteristics individually. The the abnormal conditions of data that is multicollinearity, outlier and heteroscedasticity under rack of the number of observations. In this paper, a CER's Linear Combining Model is proposed to overcome those limitations which guarantee more accurate estimation (25.42% higher precision) than other singular CERs. At least, this study is meaningful as a first attempt to improve the predictability of CER with insufficient data. The methodology suggested in this study will be useful to develop a complex Korean version cost estimating model development in future.

Delivering the weapons system requirements of the military to the acquirer is an essential activity for the development of the defense industry as well as the successful acquisition of a weapons system. In order to ensure successful delivery of requirements, the creation of a weapons system Operational Requirements Document(ORD) has been mandated since 7. 2013. However, according to the results of a study which analyzes recently-created ORD, a number of problems are occurring. For one, some items in created ORDs differ from what the ORD template requires. In addition, the overall mission area of the weapons system to be acquired and the core parts(operation performance, system performance, and core performance) of ORD are being poorly recorded. In response, this study presented a framework(focused on a creating method of overall contents and core parts) for the creation of ORDs which can solve the problems that arose during ORD creation in the past.
