기술적인 프로젝트를 수행하는 기관들은 전문가들의 도움을 받는 것이 보편화되어가고 있다. 프로젝트를 사전 검토하는 전문가들은 정보화 기술과 측량 및 매핑의 변화된 기술과 함께 경제적인 방법에 대한 분야에 대한 전문적인 지식이 있어야 한다. 토털스테이션, GPS, 정사사진, 수치지도 및 위성 리모트센싱과 같은 새로운 측량 및 매핑 방법은 과거의 측량 개념을 송두리째 바꾸어버렸다. 또한 매핑에 대한 기술은 지난 50년 동안 기계식에서 해석적 그리고 수치적으로 크게 변화되었다. 이제 측량 및 매핑 방법들의 적절한 선택은 특정한 기술의 사용보다는 비용과 효과 측면에서의 결정사항이 되고 있다. 예를 들어 GPS측량기는 종래의 측량기기보다 더 비싸지만 비용효율적인 측면에서 장점을 제공하고 있다. 본 연구에서는 측량 및 매핑 프로젝트에서의 비용인자와 효과인자를 독립적으로 평가하였고, 비용/효과 비(B/C비)를 평가모델에 사용하여 각 측량방법의 비용 효과를 비교하였다. 측량 및 매핑 방법들의 비용 대 효과 모델은 전체 프로젝트에서 경제적인 결과를 얻을 수 있을 것이다.

시장 환경 변화가 심한 상황에서 정보화로 기대되는 효과가 기업의 성과에 직결되지 않는 한 적극적인 IT 투자는 기대하기 어렵다. 경영자의 IT투자 의사결정을 유도하기 위해서는 IT투자의 사전평가를 통해 그 투자의 타당성을 입증하는 것이 중요하다. 본 논문은 IT 투자와 그 투자에서 얻어지는 효과를 사전에 분석하여 투자타당성을 평가할 수 있는 방법론을 제시한다. 이 방법론은 IT 소유비용을 체계적으로 분석해서 가시적 인 비용뿐만 아니라 숨겨진 비용도 파악한다. 또한 IT투자로 인한 재무적인 효과와 비재무적인 효과를 화폐가치화 하여 IT ROI를 산출한다. 본 논문은 IT 투자의 객관적인 투자 타당성을 평가하여 IT 투자 의사결정을 지원하고 효율적 인 IT 투자가 이루어질 수 있는 체 계를 제시한다.

This study first addresses the ineffectiveness of indirect regulation on industrial machines. Analysis of causes of industrial accidents associated with industrial machines further reveals the fact that technical causes need to be resolved at the manufacturing stage to reduce the frequency and strength of industrial accidents. Balanced safety certification on manufacturers and safety inspection on users of industrial machines are then suggested to effectively resolve such technical causes. The effectiveness of such safety certification and safety inspection can be justified by cost-benefit analysis. Particularly, balance in expected benefits of safety certification and safety inspection is a key issue for validity of such analysis. The accumulated benefit-costs for press brake and portable sawing machine confirm the effectiveness of such safety system.

The main purpose of this study is to analyse economic feasibility of low-carbon-oriented trawl gear. The results of benefit/cost analysis showed that use of the low-carbon fishing gear is economically feasible. Considering the fuel saving and relatively low $CO_2$ emission by reducing the resistance of gear, net present value by such gear improvement was estimated about 2,430~2,853 million won with the benefit-cost ratio 1.65~1.84 and the internal rate of return 29.18~30.48 percent. Development of low-carbon trawl gear would render significant contributions to reducing $CO_2$ emission in fishing operations and lead to reduce fishing costs due to fuel savings.

The introduction of a ubiquitous environment has realized commercial ubiquitous services in various industrial fields and government area. The central and/or local governments are demanding an appropriate investment evaluation model for ubiquitous service. Thus, this study develops and suggests an evaluation model for ubiquitous service by reflecting its characteristic of promoting public good, as well as its broad ripple effect on people. The investment evaluation model for ubiquitous service suggested by this study is based on Cost Benefit Analysis Method. Especially, the 'Benefit' is analyzed in two aspects; 'Economic Benefit', which shows the benefit that ubiquitous service providers to the overall local economy, and; 'Financial Benefit', which shows the profit of individual investors participating in the introduction of ubiquitous service. The investment evaluation model for ubiquitous service suggested by this study can be used by the central and/or local government during their evaluation for investment before introducing a ubiquitous service. Also, when introducing a ubiquitous service in public field, the model can be used to support the decision making of private businesses for investment. Finally, it can be used to promote and inform the expected benefits of introducing a ubiquitous service to local residents.

This study delivers the actual condition of investment for industrial accident prevention based on survey of 500 construction sites from 'reports far industry safety and health' published by Korea Occupational Safety & Health Agency (KOSHA). The various research techniques were used such as technical statistic analysis for construction industry, cost comparison of industrial accident prevention and accident loss. A formula was deduced to calculate accident loss and accident frequency by accident prevention cost through regression analysis.

There has not been any scientific analysis on appropriate size of workforce and salary for civilian workers in military so far. Thus, this paper conducted analysis on propriety in employment size of military doctrine researchers using system dynamic methodology based on annual military doctrine workload. Vensim software was mainly used to measure complement of the research group based on data from job analysis. Secondly, a multiple regression analysis was performed to study an appropriate wage for researchers based on their expertise and working condition. The data from twenty public research institutions and twenty eight job positions that are performing similar duty with military doctrine researchers was obtained and utilized to create a salary-estimation regression equation in the analysis. Finally, with cost-benefit analysis method this paper studied financial effectiveness of hiring military doctrine researchers. Contingent valuation method, which has been recognized as one of the most effective methodologies in cost-benefit analysis on intangible value, was utilized to measure benefit of hiring the researchers. The methodology presented in this paper can be applied to measure and improve the efficiency of military organization not only in military doctrine research area but also in several military functional area (military training, logistics, administration, combat development, and combat support).

PURPOSES : This study was conducted to analyze the effects arising from extending the duration of nighttime road construction on improving road quality and durability. METHODS : Most previous studies estimating the social cost of various construction conditions did not consider road pavement cooling time as a factor in improving road pavement quality. This study investigated the feasibility of achieving higher road quality and durability by extending the duration of nighttime road construction time extension. For this investigation, the effects of such an extension on traffic conditions were analyzed based on micro-simulation studies and scenario-based cost-benefit analyses, using factors including traffic volume, delay, construction cost, and road pavement cooling time. RESULTS : The results of the traffic simulation studies and cost-benefit analyses indicate that the current road construction method that emphasizes completing nighttime road construction by 6 a.m. reduces pavement life while causing relatively little traffic delay. If the night construction time is instead extended to 2 p.m., road pavement lifetime is increased, reducing road re-construction cost. These savings are greater than the cost of congestion arising from extending the duration of nighttime construction. CONCLUSIONS : The current nighttime construction durations need to be extended in order to efficiently manage roads and reduce road management costs.
