  • This study is an empirical analysis regarding what kind of factors affect the intention to use autonomous vehicles. For the empirical analysis the research model was derived from value-based adoption model base and integrated some aspects that only autonomous vehicles have. At default variables of VAM are usefulness, enjoyment, technicality, perceived cost, some autonomous vehicle related variables were added, and those are convenience, safety, security, social influence. A survey was done in order to empirically analyze with this research model, and 216 valid survey answers were chosen to analyze. Empirical analysis was done by structural equation using AMOS24. The result of empirical analysis were as follows. Variables usefulness, enjoyment, safety, security had a significant positive effect on perceived value. Technicality and perceived cost had a significant negative effect of perceived value. In addition, security and social influence had no significant effect on perceived value. Furthermore, perceived value had significant positive effect on intention to use. Among the variables that came out to be significantly positive, the most influencing variable was safety, followed by convenience, perceived cost, enjoyment, usefulness and then technicality. In addition, the analysis of mediating effect of perceived value shows that usefulness, enjoyment, convenience, safety, technicality, perceived cost had mediating role towards intention to use. However, security and social influence had no siginificant mediating effect towards intention to use. Considering all these research results this study has provided theoretical and practical implications to researchers on the intention to use autonomous vehicles.

  • Using the case of Taegu city, this study analyses benefits and costs related to the construction of GIS to local government. For this purpose, the study uses a case study selecting Taegu Metropolitan city. In this study, four discount rates(5%, 8%, 10%, 12%) are used for sensitivity analyses. According to this benefit-cost analysis, Taegu city government could get positive net present benefits from the year of 2004 which is 6 years after its GIS construction. This a result, Provides the economical and financial validity of GIS Construition in local government. In this study, analysis of invisible benefits are excluded. If these invisible and potential benefits are included in the analysis, GIS could produce more net benefits and the even break point of GIS construction in local governments will come earlier. For the further study, the study needs to develop new benefits and utilize cost-effectiveness analysis to catch these invisible benefits.

  • Current removing process is labor intensive and time consuming, employing a conventional grinding type manual machine. From a social and economic point of views, these kinds of manual tasks bring about social inconvenience and economic loss including traffic jam and high labor costs. The objective of the study was to develop and evaluate a road stripe removal equipment using water jet technology. The following shows the results. First, It was analyzed that the obtainable productivity from the equipment developed in the study is 280% compared to the current equipment. In this study, it was also calculated the Benefit/Cost Ratio and the result showed that the ratio is 3.28, so it is expected that the equipment can produce great benefits for the relevant companies. Second, an analysis was also conducted on the traffic congestion cost, and the equipment could save about \2,550 million per day compared to the conventional equipment. Therefore, it is analyzed that the economic viability of the equipment is sufficient.

  • On the basis of equal health hazard risk, economic assessment of nuclear was compared with that of coal for the expansion planning of electric power generation in the year 2000. In comparing health risks, the risk of coal was roughly ten times higher than that of nuclear according to various previous risk assessments of energy system. The zero risk condition can never be achievable. Therefore, only excess relative health risk of coal over nuclear was considered as social cost. The social cost of health risk was estimated by calculation of mortality and morbidity costs. Mortality cost was $250,000 and morbidity cost was $90,000 in the year 2000.(1986US$) Through Cost/Benefit Analysis, the optimal emission standards of coal-fired power generation were predicted. These were obtained at the point of least social cost for power generation. In the year 2000, the optimal emission standard of SOx was analyzed as 165ppm for coal-fired power plants in Korea. From this assessment, economic comparison of nuclear and coal in the year 2000 showed that nuclear would be more economical than coal, whereas uncertainty of future power generation cost of nuclear would be larger than that of coal.

  • The value of a statistical life (VSL) plays a very important role in estimating the benefits of environmental policy. It is used, for example, as a unit of monetization of health benefits resulting from the reduction of air pollutants, which is the basis of cost-benefit analysis of policies. The VSL can be defined as the value that people of each society are willing to pay to reduce the risk of death, so the value should reflect the characteristics of its members. In this study, we apply a choice experiment with 3,081 respondents collected through a web survey were divided into two samples according to the type of questions. Among the various estimates, the most appropriate estimate of the VSL is about 1.3 billion won from 1,528 sample, which is similar to the results of the meta-analysis using estimates from prior studies conducted in Korea. In addition, this study shows that a private prevention program is preferred to reduce the risk of death from cancer rather than a public program.

  • People believe that they make a rational decision. But the results of behavioral economics research show that people make a emotional decision at many times. The perception of fairness is one of the example in emotional decision. Sometimes people give up their monetary profit and revenge counterpart when they feel unfair. So the perception of fairness is very important. Two experiment was conducted. In experiment 1, researcher studied the effect of the pre-investment cost in perception of fairness. The result showed people who had pre-investment cost thought more unfair but were more likely to continue prior decision. In experiment 2, researcher studied the effect of type of CEO and message frame in perception of fairness. The results showed that people thought the proposal was more unfair when CEO was son of founder and message was gain and loss framing message.

  • The repository for the disposal of LILW which is generated from nuclear power plants and industries is expected to be completed in 2014. For the disposal of LILW, it is important to secure a disposal facility itself, but it is also very important to establish a reasonable charging system which all shareholders are satisfied with. Korea's disposal fee for LILW is higher than other countries' fee, which is a burden to waste generators as well as the waste management organization. The partial reason for the high disposal fee is put on the high social and construction cost when compared with other countries. However the major reason is put on the excessive borrowing cost that is used for the construction of the LILW disposal facility. In this study, we proposed the way to reduce the excessive borrowing cost for sustainable project managements of LILW disposal by analyzing a cost structure.

  • OECD(2008) gives the concepts of inaction costs on key environmental challenges including: direct financial costs; total financial costs; total use costs; and total social welfare costs. In analyzing the losses of environmental goods' various values conducted by domestic and foreign researchers, this study suggests the value-cost category of OECD(2008) and other studies; and the indirect use and non-use values of groundwater and other natural environment using the concepts of inaction costs. The studies on the damages and their relationships among human, property, and ecosystem are essential to monetary valuation on the qualitative or quantitative degradation of groundwater and other natural environment.
