R&D expenditure of Korean firms has been increasing drastically since 1980 and occupied 84% of total R&D expenditure in 1994. After 1994, however, the growth rate of industry R&D expenditure has dropped below single digit. R&D concentration rate of upper 20 companies declined from 61.9% in 1999 to 49.8% in 2001. The technology trade balance has diverged by 2.8 billion dollars in 2000 compared to around 0.3 billion dollars in 1985. We find several reasons on declining the industry R&D growth rate in Korea. First, we carefully say there might be an crowding out effect in increasing government R&D investment from Granger causality test between industry R&D and government R&D. Second, the decreasing benefit of tax credit since 1992 on industry R&D expenditure has caused the decrease of industry R&D growth rate. Third, the type of R&D cost becomes to similar to matured countries type of cost, which means the portion of capital expenditure has been decreased since late of 1980s. Therefore, industry R&D growth rate gets to saturation point. We draw several policy implications from the changing structure of business R&D of Korean company. Firstly, to stimulate industry R&D investment Korean government needs to strengthen tax credit policy. Secondly, to induce foreign direct investment Korean government needs to establish technology infrastructures and high quality of manpower. To utilize foreign technology resources Korean government need to introduce global R&D program executed by foreign scientist as an Project Leader.

High temperature fuel cell system, such as molten carbonate fuel cells(MCFC) and solid oxide fuel cells(SOFC), are capable of operating at MW rated power output. The power output change of high temperature fuel cell imposes the thermal and mechanical stresses on the fuel cell stack. To minimize the thermal-mechanical stresses on the stack and increase the systems reliability, we should divide the power plant configuration to several banks. However, the improvement of reliability in fuel cell power plant system causes an increase of the investment cost, for example, replacement costs, labor costs, and so on. For this reason - the balance between investment and reliability improvement - many studies about the appropriate level of investment have been conducted. In this paper, we evaluate the cost for operation and installation, the benefit for electric energy and thermal energy sales, and the system reliability for several cases : these cases relate with the bank configuration.

RFID system the key technology of ubiquitous era, has been emphasized in logistics. Logistic enterprises are required to apply RFID systems considering their investment costs, actual effectiveness, operational satisfaction and so on. For such a purpose, many applicable methods of RFID system have been developed A method that RFID tags are directly attached to products or pallets is utilized in most cases. However, this method requires expensive investment cost, frequent replacement of damaged tags for the small and medium (SM) third party logistics. In this paper, we analyze statistically the current status and requirements of SM third party logistics. Based on their requirements, we propose the realtime warehousing-delivery management by the method to attach a RFID tag to each warehouse rack, together with the economy analysis index in order to evaluate economical efficiency. Consequently, this method is expected to reduce Investment cost and to improve operational effectiveness and satisfaction.

A recent study conducted by KOTI reported that regional and urban read congestion costs in Korea are continually rising in the ranges between 3.1% thru 4.1% of GDP in the every respective year during the past 10 years. The report explicates that the congestion problem has motivated sharp raise of the logistics expenditure from 4.4% of GDP in the year of 1998 to 16% in the year of 2003. Even though, the government has allotted annual budget in the ranges between 2.7% and 3.7% of GDP to the SOC investment for the consecutive years of past decade, the amounts are however far less and insufficient to meet with social requirements and its demands. The cost of logistics has been excessively went up much higher rate than that of other industries and that of 9.6% in Japan and United States respectively It is obvious that the high logistics cost could be a detrimental factor to fierce emulation with others in the global trade market. Therefore it is an essential matter to eliminate or exclude all the probable sources that might cause or create extra costs on logistics. In consideration of such situation in Korea, the SOC investment with private capital could be a best cogitable scheme to acquire its prompt demand solutions and stimulate the emulation ability in the international trade market what's more betterment for all of our quality life in the near future.

The cost-benefit analysis is a technique for assisting with decision about the use of society's scare resources. There exists no detailed assessment like cost-benefit analysis. But recently, many policy analysts criticized the merit of cost-benefit analysis. As it is, it can be said that partial or approximate estimates of benefit and cost may be more dangerous than helpful. The purpose of this study is to overcome the limit of traditional cost-benefit analysis. For this purpose, we use the system dynamics approach for setting up new cost-benefit analysis, which we named that ‘Dynamics Cost-Benefit Analysis'. The usefulness of ‘Dynamics Cost-Benefit Analysis' is as follows; finding structural causal relationship between cost factors and benefit factors, understanding the long-term behavior of systems economic feasibility. In this study, we apply 'Dynamic Cost-Benefit Analysis' to case that is construction investment of funeral house by local government sector.

An estimation of economic life for a new weapon system is a critical issue in aquisition process. In general a life cycle cost consists of, development cost, aquisition cost, and maintenance cost. These costs are not identified and obtained in the beginning of the aquisition process. This paper deals with an economic life for KlAl tank which is being deployed recently, using PRICE model. In order to estimate an KlAl economic life, we use equivalent annual cost method which is sum of capital recovering with return and equivalent O&M cost method. This method determines an economic life by minimizing annual investment cost and operation and maintenance cost. In this paper, an aquisition cost of KlAl is obtained from PRICE H and O&M cost from PRICE HL model. We obtained various results depending upon production quantity. An economic life for KlAl is estimated 18 years when 300 tanks are produced.

최근 대형 전력시설물에 대한 VE 와 LCC 기법의 도입은 여러 가지 형태로 수행되고 있으며, 일반적으로 전력 시설물의 비용을 생각할 때 그 초기투자비만을 대상으로 평가하는 경향이 있으나, 시설물의 총 생애비용 (보전비, 수선비, 개선비, 운용비, 전력비등)을 동시에 고려하여야 한다. 본 연구에서는 간선설계에서 장거리 급전시 전압강하로 인한 동손비를 고려한 설계기법과 내구년한에 따른 총생애비용기법을 적용하여 타당성을 입증하였다.

기업유치를 통한 안정적 경제성장과 일자리 창출은 지방자치단체에서 고려하는 중요한 정책적 과제이다. 기업은 지역의 입지여건을 고려하여 입지를 최종적으로 선택하게 된다. 그리고 지방자치단체는 상대적으로 불리한 입지여건을 극복하기 위하여 각종 인센티브를 기업유치 수단으로 활용하게 된다. 이러한 인센티브는 기업의 투자목적, 투자규모, 투자시기 등에 따라 상이하게 적용되어야 한다. 그러나 지자체에서는 동일한 법률체계 하에서 유사한 지원을 통해 유치활동을 전개하고 있다. 이로 인해 실질적인 투자유치 활동의 성과와 연계되지 못하는 것이 사실이다. 따라서 본 연구에서는 강원지역에 적합한 차별화된 지원제도의 도입방안을 도출하였다. 특히 물류 및 오폐수 처리 비용지원, 교육훈련보조금의 상향 조정 등 투자유치 지원제도의 구체적인 개선방안을 모색하였다.
