This study attempts feasibility analysis of cataloging outsourcing. The economic analysis model based on information economics categorizes the benefit into direct benefit and value linking. We measure direct benefit by cost savings and cost avoidance, value linking by the degree of improvement in cataloging quality The results show that there is no feasibility overall, because librarians spent more time to control the quality due to vendor's lack of professionalism, resulting little effect on cost savings. When cataloging outsourcing is forcibly used under the economically infeasible condition, it is impossible to achieve the basic purpose of operating cost savings and improvement of service function.

This research was conducted to investigate the feasibility of aviation safety technology development. The important subjects of aviation safety technology development, aviation accident prevention and damage reduction technique, aircraft safety certification development, BASA promotion in an aircraft class, were included to investigate the the feasibility of aviation safety technology development. The survey technique using Benefit-Cost Anlysis was performed and the results showed that aviation safety technology development brought scientific technique effect, industrial and economic effect, and the rest effects. Also, the benefits from aviation safety technology development were much greater than the costs.

For economic impact analysis on a R&D project of groundwater remediation in the metropolitan areas conducted as a fundamental research programme of KIGAM from 1998 to 2002, benefit/cost ratio(BCR), net present value(NPV), and internal rate of return(IRR) were calculated using a contingent valuation method(CVM). Measurable direct benefit parameters among the major outputs of this project consist of setup of drinking water facilities and groundwater information data valuation. In this study, economic impact of the project in NPV of year 2002, with applying a discount rate of $10.0\%$, was identified and estimated as 5.09 billion won in cost, 67.69 billion won in benefit, 62.60 billion won in NPV, 13.3 points in BCR, and $152\%$ in IRR, respectively.

While many success stories are reported in the area of RFID applications, actual RFID deployments in industry are being realized a lot slower than expected. One of the main reasons for that is the lack of decision makers' understanding on the RFID ROI. In this research we drew a comprehensive list of cost and benefit items regarding RFID deployments especially for distribution and retail industry. In addition, we mapped these cost/benefit items to corresponding SCOR processes so that users can easily utilize the suggested cost-benefit analysis model when they want to improve their own processes using the RFID technology. The developed cost-benefit analysis model was implemented as a software tool for convenient use. Our research results can be used not only for those who want to evaluate the RFID technology prior to actual deployment but also by the researchers in this area.

The economic appraisal of a port remodeling project must be transparent and persuasive to the public over the entire stage of the project. A project evaluator need to be familiar with the guidelines on evaluation, and to do his best to follow the guidelines to evaluate the given project. To make the right decision on investment, the evaluator must take into consideration not only economic efficiency, but also equity issues such as income redistribution and balanced development between regions. Port remodeling projects tend to produce externalities to the environment. However, these externalities are of qualitative nature, and hard to measure in monetary terms, so these are liable to be ignored in the process of project evaluation. Two different approaches - RP(revealed preference) and SP(stated preference) have been tried to assess the value of these non-market goods. Government authorities need to set minimum guidelines which project evaluators must follow in order to make the evaluation more reliable.

For economic impact analysis on a R&D project of high-yield groundwater development in Jeju conducted by KIGAM from 2004 to 2007, benefit/cost ratio(BCR), net present value(NPV), and internal rate of return(IRR) were calculated by contingent valuation method(CVM), production function analysis, domestic water market analysis and technology factor analysis. Measurable direct impact parameters among the major outputs of this R&D project consisted the estimation 4 high-yield and high mineral groundwater reserve in Jeju. Annual use of the reserve by piped water and bottled water was estimated as 12.23 million ton and its monetary value was calculated as 293.4 million dollar in 2006 year value applied of 5.5% discount rate. Economic impact of this R&D project in NPV of year 2006, with applying a discount rate of 5.5%, was identified and estimated as 13.66 million dollar in NPV, 4.05 points in BCR, and 22.74% in IRR, respectively. Additional early launch benefit was 5.58 million dollar. Even increased of the 1% discount rate, NPV of this R&D project was also positive as 12.18 million dollar and BCR was 3.71.

Environmental impact is getting more attention in many feasibility studies for railroad-related projects and research items. For sustainable growth and green transportation, the benefits typically used for feasibility studies in railway-related projects, are composed mostly of economic criterions which is not considering growing attention on changing paradigm. Based on the analysis of current methodologies, improvements in estimating environmental impact especially on noise and pollution are suggested. Active steering bogie has been proposed to satisfy stabilizing and steering performance of railroad. This paper describes the feasibility study of the active steering bogie for a urban railway vehicle based on environment-related criteria.

In this paper we have shown that a Pigouvian tax is an adequate resolution of congestion externality to attain Pareto optimality using utility maximization. For this objective, taking an open access freeway as an example, we not only derived both marginal private benefit and marginal social benefit, but also assessed the divergence between marginal private benefit and marginal social benefit. As a result, we identified that the amount of a Pigouvian tax should be the same amount as the external time cost, which is the value of the marginal time cost to Individual a incurred by Individual b through freeway congestion. This Pigouvian tax coincides with the profit or wealth maximizing toll suggested by literature on the basis of profit maximization. In addition, because an open access freeway is accounted as common property resource, we proved that average social congestion cost is essentially equal to marginal private congestion cost in our model. Finally, we showed that the optimal value of trip derived in our model is the same as that generated on profit maximization approach.

The relationship between climate changes and transportation could be separated by two approaches. One of methods was to find how climate changes affected transportation, and the other way was how transportation affected climate changes. In this study, we reported from the former standpoint, how climate changes affected transportation fields. When there is a lot of snowfall in Seoul, it starts ripple effect through the travel patterns. They can be explained by travel time and operating cost. The travel costs were calculated in this paper for analysing the effect of disbenefit by climate changes. Snow Melting System was also studied for relieving negative influences under the unpredictable weather condition. As a result, the system was effective for minimizing disbenefit by climate changes.

국가과학기술연구망(KREONET)은 초고성능 슈퍼컴퓨팅, 그리드(Grid), e-Science 등 국내의 첨단 과학기술분야에 관한 연구 개발을 지원하고 있는 국가연구망(National Research Network)이다. 그러나 국가연구망이 국가연구개발 사업의 전반에 걸쳐 직 간접적으로 많은 영향을 미침에도 불구하고, 이러한 파급효과에 대해 체계적인 분석이 없는 실정이다. 따라서 본 논문에서는 KREONET에 대한 경제성 분석을 통해 국가과학기술과 산업발전에 미치는 파급효과를 분석하고자 한다. 분석방법으로는 KREONET의 존재 유무에 따른 비용편익분석과 산업연관분석을 사용하였다. 비용편익분석의 평가지표로는 순현재가치, 비용편익비율, 내부수익률을 사용하였고, 산업연관분석의 평가지표는 생산유발효과, 부가가치 유발효과, 취업유발효과를 사용하였다. 분석한 결과, KREONET은 경제적 파급효과가 높은 것으로 나타났다. 본 연구의 결과를 다른 연구망에 적용하기 위해서는 보다 다양한 범주의 평가범위와 평가방법에 대한 연구가 지속되어야 할 것이다.
