농업부문이 사회에 제공하는 다양한 긍정적 외부효과가 인정됨에 따라, 대부분의 농업생산기반시설은 국부를 증진시키는 사회간접자본으로 인식되고 있다. 과거에는 수리시설을 비롯한 기반시설이 단지 생산성 향상을 위한 사회적 투자로 간주되었으며 따라서 사업에 대한 경제성 분석 또한 직접적인 경제적 효과에 대한 편익비용분석에 국한되었다. 그러나 최근에는 농업 및 생산기반시설이 제공하는 비시장적 가치가 점차 인정됨에 따라 그러한 가치 또한 경제성분석에 포함될 수 있다

국내단행본 디지털화의 비용과 편익을 정량적, 정성적으로 분석하여 디지털화에 소요되는 비용과 편익을 구체화한다. 비용항목으로는 국내단행본 디지털화에 투입되는 정보시스템비, 인건비, 유지보수비, 디지타이징 비용을 측정하며, 편익항목으로는 도서관측면의 대출시간 절감편익, 운영비 절감편익 등으로 산출하며, 이용자측면은 접근편익, 대출시간 절감편익, 교통시간 절감편익 등을 분석하여 경제성을 도출한다.

In this study, we tried to develop the Web-GIS system prototype that will be able to effectively manage the nationwide flood prevention operations and to establish a framework that will be able to maintain the operation consistency. To achieve the study goals, we analysed current system of flood prevention operations, gathered related documents, had interviews with many government employees, and developed the Web-GIS system prototype. Also, we tried to present the benefit-cost analysis method using GIS technique that will be used to decide the priority order of the operation.

For a successful construction project not only construction engineering and project management technology but also economic evaluation technique is required. Design and construction technologies are necessary to receive a project order. However, construction management technology which can be apply from the project initial phase to the project operation and management phase is required to create a benefit from the project. Construction management technology is one of the effective factors for project success. Economical and efficient cost management from the planning phase influences the project success. This study investigated cost flow and cost factors of domestic Sewage Treatment Plant project for systematic analysis of cost items following the entire project phase. Particularly, data modeling based on domestic Sewage Treatment Equipment maintenance cost DB was performed, and maintenance cost estimation trend line is suggested using Monte carlo Simulation Method to decrease uncertainty of actual results DB and for feasibility study.

The automotive industry is facing a paradigm shift, changing from owning to sharing and from manufacturing to service. However, it is hard to conclude that the economic value of smart mobility service is always positive to users. Cost related to owing or share a vehicle is very hard to estimate from the perspective of potential users as well as the benefit of the service. Focusing on the cost side of the story, this study develops a cost estimating model based on three main factors: electrification, advanced driving assistant systems (ADAS) function, and participation of ride-sharing service. As a result of the model analysis, low cost was estimated as a result when receiving cost benefits such as electrification and ride-sharing participation. Various factors were analyzed through sensitivity analysis also. These results can provide useful insights into the cost prediction and strategies for potential users and manufacturers on smart mobility service market.

In this paper, related studies were investigated by dividing them into cost-benefit analysis, security continuity services, and SW-centric calculations. The case analysis was conducted on A institutions in the United States, Japan and South Korea. Based on this, an improvement model was prepared through comparison with the current system. The SCS(Security Continuity Service) performance evaluation system-based information protection service cost calculation model is proposed. This method applies a service level agreement(SLA) and NIST Cybersecurity framework that are highly effective through cost-effectiveness analysis and calculates consideration based on characteristics, performance criteria, and weights by information protection service. This model can be used as a tool to objectively calculate the cost of information protection services at public institutions. It is also expected that this system can be established by strengthening the current recommended statutory level to the enforceability level, improving the evaluation system of state agencies and public institutions, introducing a verification system of information protection services by national certification bodies, and expanding its scope to all systems.
