본 연구에서는 국내 금융투자기관의 효율성 분석을 위해 코참비즈에서 제공하는 재무데이터를 이용하여 2009년도 영업이익순위 30위이하의 금융투자기관을 중심으로 DEA분석방법을 적용한 CCR-I, BCC-I 효율성과 규모수익성(RTS)평가를 통해 금융투자기관의 효율성을 분석함으로써 벤치마킹의 대상이 될 수 있는 국내 금융투자기관을 확인하고, 비효율적인 기업을 위한 각 기업이 개선시켜야하는 투사 값을 제시함으로써 기업의 효율성을 위한 수치를 제공함과 동시에 분석된 자료를 바탕으로 벤치마킹의 대상이 될 수 있는 금융투자기관을 제시하고자 한다.

Each method for economic evaluation has its own characteristics. Therefore adoption of each of them in evaluation production investment project results in many problems. Hence combination & modification of them are required to perform more accurate evaluation about investment project. This paper discuss evaluation method of investment projects expansion and replacement investment on each line or individual in the production. Generally investment evaluation method has add to a few method by Subsidiary means with use a especial method. And then in this paper, a Taguchi Techniques is presented, which may be effective to the facilities appraisal or improvement. We propose a decision model to incorporates the values assigned by a group of experts on different factors in production. Using this model, SN ratio of taguchi method for each of subjective factors as well as values of weights are used in this comprehensive method for reducing production rate in production management.

Singapore's inward and outward investments with industrialized countries in both manufacturing and service sectors were skill seeking while outward investments to developing countries were labor seeking. Applying the Knowledge-Capital model, it was found that services Foreign Direct Investment is sensitive to skill differences. A ten-percent decline in skill differences with industrialized countries resulted in a 4.25 percent rise in inbound manufacturing and 1.48 percent rise in inbound services investments. Meanwhile, a ten-percent increase in skill differences with developing countries resulted in a 30 percent rise in outbound manufacturing and 0.38 percent rise in services investments. Furthermore, when services are distinguished by skill-intensity, the impact of relative skill endowments on inbound Foreign Direct Investment in skill-intensive services is significantly different from the impact on other services. However, when services are disaggregated by "proximity" needs, we do not find any significant difference in the impact of relative skill endowments on Foreign Direct Investment.

본 논문에서는 경제성 평가를 기반으로 하는 배전 설비투자 우선순위를 결정하기 위하여 배전계통 구성, 설비 및 부하정보를 이용하여 배전계통을 모델링 하고, 현 계통의 신뢰도를 개선하기 위한 방향으로 설비투자 대안들을 설계한 다음, 이 대안들을 대상으로 신뢰도 및 경제성을 평가하는 모델을 제시하였다. 이러한 투자대안들의 신뢰도 영향과 경제성을 분석하기 위하여 한전의 주요 배전설비(15종)의 신도율(시변고장율)과 설비투자시 영향을 받는 고객들의 정전비용을 적용하여 경제적 효과를 산출하였으며, 이러한 투자 방법론의 유효성을 검증하기 위하여 한전의 배전사업소 실제 투자안을 대상으로 하여 경제성 평가를 수행한 결과와 비교분석하였다.

본 연구에서는 CGE(Computable General Equilibrium)모형을 이용하여 28개 산업별 R&D투자액의 GDP 파급효과를 추정한 뒤, 그 결과로써 GDP의 R&D투자탄력성을 계산하여 산업별 R&D 투자 우선순위를 제시하였다. 우선순위는 28개 대분류 산업 중 전체 연구 개발투자에서 차지하는 비중이 1% 미만인 16개 산업을 제외한 12개 산업에 대해서만 적용해 보았다. 먼저 GDP의 R&D투자 탄력성에 근거한 우선순위는 제1차 금속제품, 화학제품, 음식료품, 전기 및 전자기기, 수송장비, 금속제품, 정밀기기, 전력 가스 및 수도, 일반기계, 통신 및 방송, 건설, 사회 및 기타 서비스, 부동산 및 사업 서비스 순이었다. GDP의 R&D투자탄력성에 근거한 순위설정은 비교적 우리나라 산업들의 현황을 잘 보여주고 있는 것으로 판단된다. 보조 지표인 2030년 기준 균형 대비 GDP 증가율에 근거한 우선순위 역시 판정기준으로 유사한 결과를 보여주었다. 결국 두 개의 우선순위 기준은 국가과학기술위원회의 R&D예산투자방향 및 기준 설정과 주요 사업별 예산배분 방향에 좋은 판정기준으로 활용될 수 있음을 보여주었다.

Funtional metal prototypes are often required in numerous industrial applications. These components are typically needed in the early stage of a project to determine form, fit and function. Recent R/P(Rapid Prototyping) part are made of soft materials such as plastics, wax, paper, these master models cannot be employed durable test in real harsh working environment. Parts by direct metal rapid tooling method, such as laser sintering, by now are hard to get net shape, pores of the green parts of powder casting method must be infiltrated to get proper strength as tool, and new type of 3D direct tooling system combining fabrication welding arc and cutting process is reported by song etc. But a system which can build directly 3D parts of high performance functional material as metal part would need long period of system development, massive investment and other serious obstacles, such as patent. In this paper, through the rapid tooling process as silicon rubber molding using R/P master model, and fabricate wax pattern in that silicon rubber mold using vacuum casting method, then we tranlsated the wax patterns to numerous metal prototypes by new investment casting process combined conventional investment casting with rapid pototyping & rapid tooling process. with this wax-injection-mold-free investment casting, we developed new investment casting process of fabricating numerous functional metal prototypes from one master model, combined 3-D CAD, R/P and conventional investment casting and tried to expect net shape measuring total dimension shrinkage from R/P part to metal part.

This research aims to examine the model of investor herding behavior in making investment decisions in the Indonesian capital market, which is influenced by social and information impacting on the value of the Book Value Per Share (BVPS). The latest stock market conditions show that most investors make the same error pattern in making investment decisions that result in losses. The experiment involves two independent variables, namely, information about BVPS and social influence. This study used a 2×2 factorial design laboratory experimental method. Data collection was carried out through treatment of a sample of 100 individual investors listed on the Indonesia Stock Exchange. Univariate Two-Way Analysis of Variance (ANOVA) statistical tool was used to test the independent variable on the dependent variable. Research results showed that the social influence originating from expert investors is more influential than the Book Value Per Share (BVPS) information on the behavior of herding investors in making investment decisions. These findings suggest that investors know their psychological factors, thereby increasing self-control and investment analysis skills. Further research can use psychological bias and other indicators of accounting relevant information such as Earning Per Share (EPS) to test herding behavior in investment decision making in the capital market.

This paper empirically verifies that the types of capital adjustment costs serve as an important mechanism in relation to investment decision-making after confirming that the investment dispersion of Korean firms is pro-cyclical and can affect business cycles. Specifically, it is found through empirical methods using corporate financial data that capital adjustment costs generally assumed to take a quadratic form in macroeconomics are asymmetric and irreversible in the Korean economy. In particular, capital adjustment costs are empirically proven to cause investment dispersion to expand given that the substitution effect of the marginal value to the marginal cost for one unit of investment in the inter-temporal investment decision is affected by that cost with regard to the resale of owned equipment assets, as opposed to new investments in equipment assets. We ultimately show, albeit indirectly, that investment dispersion can affect business cycles as capital adjustment costs influences investment decisions. What is implied is that the capital adjustment cost is not merely an exogenously deep parameter that fits the dynamics of business cycles in a macroeconomic model but could instead be a policy variable that can be endogenized through government policies.

재고투자와 경기변동의 관계를 설명하는데 있어 생산평활(production smoothing) 가설과 재고소진 회피(stock-out avoidance) 가설은 서로 상반된 입장을 취하고 있다. 기업의 재고 투자에 관한 의사결정은 두 가지 동기 모두에 의해 영향받을 것으로 생각되지만 경기국면에 따라 각각의 영향력의 상대적 크기 혹은 방향성이 다르게 나타날 수 있다. 이에 본고는 재고투자 동학에서 생산평활 동기와 재고소진 회피동기의 상대적 유의성을 실증적으로 검증하되 경기국면별 비대칭성의 존재와 형태를 규명하는 데 분석의 초점을 둔 점에서 기존 연구와 차별성을 지닌다. 이를 위해 기존의 선형 재고투자 모형을 확장한 비선형 모형을 설정하였으며 이러한 방식이 기존 방식에 비해 우수한 지를 모형의 예측력을 비교 평가하여 확인하였다. 분석 결과, 재고투자 동학의 경기국면별 비대칭적 특성을 확인하였다. 경기 호황기에는 재고소진 회피동기가 나타나지만 생산평활 동기는 유의하지 않았다. 반대로 경기 불황기에는 재고소진 회피동기는 유의하지 않지만 Ramey (1991)에서 제시된 생산비용의 비볼록성에 의하여 재고변화가 경기침체를 심화시키는 경기 의존적 특성을 발견하였다. 경기국면별 비대칭성을 모형에 고려함으로써 그렇지 않은 모형에 비해 예측력을 향상시킬 수 있음을 표본 내 및 표본 외 예측, 다양한 예측력 검정을 통해 확인하였다. 본 연구의 결과는 재고투자의 동학과 경기 불안정화 특성에 대한 이해를 제고하여 경제전망 등에 활용될 수 있을 것으로 기대된다.
