Ever since Benoit's(1973, 1978) study, the relationship between defense spending and economic growth has been the subject of extensive empirical works. While a number of studies have reported that higher defense expenditure stimulate economic growth, many other studies have reported that an increase in military burden may hinder economic growth. To the extent that countries differ substantially in socioeconomic structures, the effects of defense spending cannot be generalized across countries. In this paper, Granger causality tests are performed between Korean defense expenditure and economic growth, consumption, investment, inflation and unemployment rate during the period from 1970 to 2002. The results show that Korean defense expenditure did not affect economic growth and unemployment rate. However, Korean defense expenditure caused consumption and inflation to decrease and investment to increase. On the other hand Korean defense expenditure was not Granger-caused by economic growth, consumption, investment, inflation and unemployment rate. In conclusion, the opportunity cost of Korean defense expenditure seemed to be relatively moderate considering Korean security environment. Even if it was not statistically significant, Korean defense burden at least did not bother economic growth.

Determination of weekly and daily energy expenditure was made on 62 Republic of Korea Army cadets who were selected at random in order to estimate the weekly and daily ealorie expenditure. Basal metabolic rate (B.M.R.), and energy cost of various military and daily activities were measured by indirect calorimetry using open circuit method. Time-motion studies were also carried on using a stop-watch. The total weekly energy expenditure was calculated by summation of data using energy cost per minute, and the time spent on each activity. Determination of daily energy expenditure was deduced from each data of weekly energy expenditure. Food survey was also carried on for a week, and daily calorie intake was determined by a weekly average discounting loss in cooking. All measurements were determined from the Standard Table of Food Composition published by the Ministry of National Defense (1961). Following data were observed. 1. Physical status of cadets are as follows. Please note that the height and weight averages are 1-2cm and 4-5kg respectively over that of the Seoul National University students. First year Height 167.92 cm $(S.D.{\pm}4.09)$ Weight 61.72 kg $(S.D.{\pm}4.53)$ Second year Height 167.89 cm $(S.D.{\pm}3.46)$ Weight 63.01 kg $(S.D.{\pm}4.61)$ Third year Height 168.15 cm $(S.D.{\pm}4.24)$ Weight 43.48 kg $(S.D.{\pm}5.03)$ Fourth year Height 168.10 cm $(S.D.{\pm}3.70)$ Weight 64.02kg $(S.D.{\pm}5.10)$ 2. The B.M.R. of cadets averaged $36.57\;Cal./m^2/hr.(S.D.{\pm}3.63\;Cal./m^2/hr.)$ is almost equal with data on the same ages of civilians and the Japanese, but a lower average of $5.1\;Cal./m^2/hr.$ than that of a common soldier. 3. The energy expenditure during various military activities is close agreement with Consolazio. Passmore and Durnin, and Japanese reports.

This study proposes a mathematical model that can forecast national defense expenditures. The ongoing European debt crisis weighs heavily on markets; consequently, government spending in many countries will be constrained. However, a forecasting model to predict military spending is acutely needed for South Korea because security threats still exist and the estimation of military spending at a reasonable level is closely related to economic growth. This study establishes two models: an Auto-Regressive Moving Average model (ARIMA) based on past military expenditures and Transfer Function model with the Gross Domestic Product (GDP), exchange rate and consumer price index as input time series. The proposed models use defense spending data as of 2012 to create defense expenditure forecasts up to 2025.

The PMB(performance measurement baseline) is the total time-phased budget plan against which program performance is measured. Additionally it is the schedule for expenditure of the resources allocated to accomplish program scope and schedule objectives, and is formed by the budget assigned. In this paper, we suggest an improvement of the R & D(research and development) program for defense acquisition by using the PMB and an application of the IBR(integrated baseline review) to review the PMB for project manager of the defense agency.

Recent development in science and technology has modernized the weapon system of ROKN (Republic Of Korea Navy). Although the cost of purchasing, operating and maintaining the cutting-edge weapon systems has been increased significantly, the national defense expenditure is under a tight budget constraint. In order to maintain the availability of ships with low cost, we need accurate demand forecasts for spare parts. We attempted to find consumption pattern using data mining techniques. First we gathered a large amount of component consumption data through the DELIIS (Defense Logistics Intergrated Information System). Through data collection, we obtained 42 variables such as annual consumption quantity, ASL selection quantity, order-relase ratio. The objective variable is the quantity of spare parts purchased in f-year and MSE (Mean squared error) is used as the predictive power measure. To construct an optimal demand forecasting model, regression tree model, randomforest model, neural network model, and linear regression model were used as data mining techniques. The open software R was used for model construction. The results show that randomforest model is the best value of MSE. The important variables utilized in all models are consumption quantity, ASL selection quantity and order-release rate. The data related to the demand forecast of spare parts in the DELIIS was collected and the demand for the spare parts was estimated by using the data mining technique. Our approach shows improved performance in demand forecasting with higher accuracy then previous work. Also data mining can be used to identify variables that are related to demand forecasting.

연구개발비가 기업의 R&D 성과로 이어지는가에 대하여 상반된 선행연구들이 존재한다. 보통 기업의 R&D 투자와 성과는 국가별, 산업별, 거시경제 상황 등이 복합적으로 작용하므로 인과관계를 독립적으로 분리하여 분석할 수 없기 때문이다. 또한 R&D 성과는 후행지표로 투자 시점과 성과 시점 사이의 시차가 존재하여 R&D 투자와 성과 간의 관계를 분석하기 어렵다. 하지만 방위산업의 경우 방위력개선비를 통해 지속적으로 R&D 투자가 발생하고, 방산업체는 이를 사업비로 사용하여 연구개발이 진행되므로 R&D 성과를 확인하기가 비교적 용이하다. 본 연구는 방위산업을 대상으로 R&D 투자와 성과 간의 인과관계를 찾고, 성과에 영향을 미치는 요인을 분석한다. 방위사업법에 의해 지정된 총 100여개의 방산업체 중 R&D 성과지표 획득이 용이한 대기업 및 중견기업들을 대상으로 최근 10년간의 기술지표, 과학지표, 재무지표에 대한 패널 데이터를 수집했다. 이를 패널데이터 분석을 통해 분야별(화력, 항공유도, 함정, 통신전자) R&D 투입과 성과 관계를 확인하고, 어떤 요인이 성과에 영향을 미치는지 찾고자 한다. 본 연구 결과는 중장기 국방정책 수립 시 의사결정의 기초자료로 활용이 가능할 것으로 보인다.

150개 군수업체를 대상으로 실시한 설문조사를 통해, 국방규격 및 민간표준 규격에 대한 활용 실태와 국방규격의 KS 부합화에 따른 경제적 효과 분석을 수행하였다. 대부분의 업체에서는 기업에서 활용하는 국방규격이나 인용 규격의 최신 변경사항에 대한 충분한 정보를 얻지 못하는 것으로 나타났다. 특히, 국방규격은 정보에 대한 접근 제한성으로 인해 최신 동향을 파악하기가 어렵다는 응답이 많았는데, 이는 국방규격이나 도면 검색 프로그램에 대한 활용을 통해 다소나마 해결될 것으로 판단된다. 국방규격의 KS 부합화 사업에 대해서는 많은 업체에서 품질향상, 연구 개발기간 단축, 생산성 증대, 표준 구매 및 교육 비용 절감 등과 관련하여 군수품 원가 절감에 다각적으로 기여할 것으로 예상하는 것으로 나타났다.

Sun Tzu once clarified that "One who knows the enemy and knows himself will not be endangered in a hundred engagements, " while Clausewitz explained that "A victory will be guaranteed for one who can overcome 'fog and friction' at a battlefield." Now the U.S. is striving hard to develop an American version of RMA (Revolution in Military Affairs)/MTR (Military Technical Revolution) by utilizing its rapidly emerging information technology in the information age. The U.S. firmly believes that its RMA/MTR with less defense expenditure can provide all combat players in the battlespace with "dominant battle awareness, " by which no nation will be able to challenge U.S. military superiority. In this paper, the recent efforts of the U.S. Armed Forces on RMA/MTR will be briefly introduced, some lessons and expertises from the U.S. RMA/MTR are extracted, and, in this regard, several suggestions are provided for the progress of the ROK Armed Forces.gress of the ROK Armed Forces.
