국방비는 국가경쟁력에 바탕을 둔 국가 방위능력 확보를 위한 투자비로, 일정비율 이상의 연구개발예산을 포함한다. 그러므로 우리군이 추진하고 있는 첨단과학기술 기반의 미래 전장환경 구축, 무기체계 및 핵심기술 획득의 국방개혁 2020의 구현을 위한 연구개발예산의 안정적 확보가 필요하다. 특히 미래전에 대비한 국방과학기술 역량의 선진화는 우리군이 당면한 개혁과제로 지속적인 연구와 관심이 필요하다. 본 연구에서는 16개 주요 국가를 대상으로 국방비 성장패턴과 국방과학기술 수준의 비교분석을 통해 국방과학기술 발전을 위한 안정적인 예산확보의 필요성을 제시하였다.

Defense firms' excess profitability by shifting common overhead costs from non-defense sector to defense sector in the award of cost reimbursement type of defense contracts is a widespread conclusion in prior researches. In this paper, we reviewed cost-shifting incentives in defense-contracting firms and extended the analysis of McGowan and Vendrzyk(2002) by applying modified model to Korea Defense Contracts. We formulated six hypotheses to test the relation of cost-shifting and excess profitability regarding market openness, auditing system, ranking in defense contracts, and firm types(sole defense contractors, sole non-defense contractors, and defense and non-defense mixed contractors). But, we could not find any evidence that defense firms shifted costs from non-defense sector to defense sector for the period 1997-2002. The results suggest that the excess profitability of Korea defense firms may not be from the cost-shifting but from other reasons.

The recent issue on the withdrawal of U.S. Forces from Korea Suggests an Urgency of Self Defense of Korea. The expected huge defense budget and her armed forces create a need for an operational analysis. It is shown through a statistical analysis what some of the opportunity costs of defense spending have been. Some evidences about what some of the economy sacrifice if defense spending rises have been analyzed to provide executive departments with a quantitative basis for decisions. The Korea-U.S. alliance is discussed in view of the developmental effects of U.S. aids and deterrent effects of U.S.F.K.

Defense analysis & evaluation includes menace analysis, validation analysis, problem analysis, scientific technical analysis, technical trad-off analysis, alternative analysis, cost analysis, etc. Reliable related data is required to perform these analysis activities efficiently. but in case of these defense analysis & evaluation data acquisition system, the data is insufficient and scattered about each organization. the data of database system is also not utilized sufficiently. abroad technical data is also low level data such as catalog or military officer's collection. therefore, this paper propose defense analysis & evaluation data acquisition system by systems engineering process. we also propose construction method of data acquisition system.

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.

Defense industries which require high reliability need an optimized quality management system with well-planned implementation. And the government should examine the overall status of defense industries, then establish practical policies with a proper support plan in required areas to upgrade the quality management level of manufacturers. Thus, DTaQ developed the model for 2 years from 2014, which specialized in quality management level analysis for defense industries. And a survey has been undertaken with that model by DTaQ and Korea Research Center in 2016. The surveyed companies randomly sampled among those which have more than 30 employees and delivery history over past 3 years, and finally 106 defense industries were selected. This paper present survey method and indexes for survey of defense industry quality management level. The survey was conducted in the order of planning, data collection and data processing, and the validity and reliability of the data were verified to increase objectivity of survey results. The survey contents mainly consist of system quality and management quality. System quality includes Product Development Management, Production Operation Management, supply chain quality management, Safety & Environment Management and Reliability Management, on the other hand, management quality includes Strategic Leadership, Human Resource Management, Customer Market Management and Information & Knowledge Management. Thus this proposes the current overall quality management status of the 106 defense industries and shows level differences by company sizes and manufacturing sectors based on the result of survey. Specifically, this paper enables to track the areas which need prompt government support with the policy directions to make quality management level higher. Therefore, it is expected that this can be used as reference data in establishing quality policies for military supplies in the future.

A flame deflector prevents a launch system from thermal damage by deflecting the exhaust flame of the launch vehicle. During the deflection of the flame, the flame deflector is subjected to a high-temperature and high-pressure flow, which results in thermal ablation damage at the surface. Predicting this ablation damage is an essential requirement to ensure a reliable design. This paper introduces a numerical method for predicting the ablation damage phenomena based on a one-way fluid-structure interaction (FSI) analysis. In the proposed procedure, the temperature and convective heat transfer coefficient of the exhaust flame are calculated using a fluid dynamics analysis, and then the ablation is calculated using a finite element analysis (FEA) based on the user-subroutine UMESHMOTION and Arbitrary Lagrangian-Eulerian (ALE) adaptive mesh technique in ABAQUS. The result of such an analysis was verified by comparison to the ablation test result for a flame deflector.

한미 방위비분담금은 1991년 1,073억 원을 부담하는 것으로 시작되었고, 2021년 1조 1,833억 원을 부담하는 것으로 규모가 점차 증가하고 있으며, 방위비 분담금에 대한 국민의 관심도 높아지고 있다. 본 연구의 목적은 한미 방위비 분담금 결정에 영향을 미치는 결정 요인(경제, 안보, 국내정치, 행정, 국제정치)을 실증적으로 분석하여 방위비 분담금 결정 과정을 보다 깊이 있게 이해하고, 방위비 분담금 산정과 집행의 효율성을 제고하는 것이다. 연구 범위는 1991년 ~ 2021년의 한미 방위비 분담금이다. 실증분석에 이용된 자료는 국방부, 정부 통계자료, SIPRI, 언론보도 등 다양한 2차 자료를 활용했다. 실증분석 방법으로 시계열을 활용한 다중회귀분석을 이용하고 자기회귀모형으로 데이터를 분석하였다. 다중회귀분석을 통한 실증적 연구 결과 우리는 아래와 같은 결과를 도출했다. 한국의 경제 규모, 즉 GDP와 전년도의 방위비 분담금, 그리고 주한미군의 병력 수치가 방위비 분담금 결정에 정(+)의 영향을 미치는 것으로 분석되었다. 이는 한국의 경제 성장이 방위비 분담금 증가에 영향을 주는 주요 요인임을 나타내며, 예산의 점진적 증가와 주한미군 주둔 비용 분담 특별협정(SMA) 협상 방식이 중요한 역할을 한다는 것을 시사한다. 반면, 집권당의 정치적 성향, 북한의 군사 위협, 중국의 국방예산 등은 방위비 분담금 결정에 통계적으로 유의미한 영향을 미치지 않는 것으로 나타났다.
