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.

U.S. National Research Council proposed benefits framework for energy R&D project as economic benefits, environmental benefits, security benefits and knowledge benefits. Following this framework, U.S. National Renewable Energy Laboratory evaluated the projected benefits of Federal Energy Efficiency and Renewable Energy Programs in the indicators of energy-expenditure savings, energy system cost savings, $CO_2$ emissions reductions. oil savings, natural gas saving and avoided additions to central conventional power. As this result, geothermal energy have predominant position in the energy-expenditure savings, natural gas saving and avoided addi t ions to central conventional power to FY2050. The projected benefits, in monetary value, of the whole supply-potential of geothermal energy in Korea were evaluated as 480.2 billion Won, 43.1 billion Won and 135.8 billion Won for the private energy-cost savings, social environmental-cost savings, and import energy-cost saving, respectively.

The purpose of this study was to present systematic interior design guidelines for the elderly housing environment. As an environmental affordance system, Murth 's user benefit criteria was employed to analyze the items of the interior design guidlines in the 5 selected elderly housing literatures. 646 items were collected from the 5 representative literatures on elderly housing design. As a result of the content anaylysis, a set of comprehensive interior design guidenlines which was systematically synthesized based on the Murtha' s user benefit criteria was presented according to the specific spaces. The behaviroral facilitation and physiological maintenance dimension most frequently mentioned in foreign literature. Perceptual maintenance dimension needed to be developed in the future in elderly housing.

This paper presents an economic analysis for the travel aids service system for visually handicapped persons through RFID (Radio Frequency Identification). This research estimates both cost and economic effect of the service. By using input-output analysis technique, three kinds of repercussion effects - domestic production, value added, and workers induced by the travel aids service - are also calculated. To evaluate the profitability of the service, we investigate the procedures through which the service has an effect on the interested parties and develop formulas describing the procedures. The benefit of the service have been generally obtained by measuring the willingness to pay (WTP). This paper, however, obtains the monetary value of benefit by estimating the parameters of the formulas, so that a close improvement of the service may be possible with the result of the economic analysis.

In this research, economic analysis of Integrated Information System for Nano-convergence Industy (hereafter 'NANOIN'), which was developed and has been in operation by Organization of Nano-convergence Industrial Cooperation, is conducted. For this purpose, the research has been carried out in the following order. First, NANOIN user's maximum willingness-to-pay is estimated using contingent valuation method, the number for NANOIN users is estimated using Bass Diffusion Model, and annual benefit from NANOIN is estimated. Next, annual cost from NANOIN is estimated using annual budget for NANOIN related planned activities. Finally, economic value of NANOIN is evaluated using economic analysis applied to the estimated annual NANOIN benefit and cost. From the economic analysis, it is found that NANOIN has some economic value. It is expected that the procedures suggested in this research can help to systematically evaluate economic value for public goods which have not only uncertain benefit from user's side but also uncertain demand just like NANOIN.

Recently, ESS became efficient device to stabilize electric power supply system with the development SG related technology. In fact. there are some constraints to supply ESS, because of the high cost and required space, but rapid technology development for ESS will make it more useful soon. So, through this paper, we analyzed the benefit and demand effect when the battery is applied the building based on the measured energy consumption. After that, we got the conclusion that there is a volume limit in ESS application, in a benefit view point. And we realized that there is a demand violation, and the Cost-based BEMS is the best solution to enhance the effect of ESS application.

This paper was conducted to study the economic valuation for Nursery-Phase production of the tidal flat oyster in Korea. Benefit-cost(B/C) model used to indicate the effects of economic valuation. Using discounting rates(i.e., 4.5%, 6.5% and 8.5%), the model compared revenues and costs that occur at different times from 2012 to 2018. This study also estimated various submodels, which are Benefit Cost Ratio(B/C ratio), Net Present Value(NPV), Internal Ration of Return(IRR), to compare profit of Nursery-Phase production styles and analyzed returns to evaluate the scenarios. Sensitivity analysis were conducted for various scenarios. The results suggest as follows. First, the oyster spat to the shell height of 3~5cm was more profit than the shell height of 1~3cm. Second, all of sensitivity analysis with submodels were economic valuation such that B/C ratio > 1, NPV > 0 and IRR > discounting rate. Third, the payback period was about 3years after installed Nursery-Phase production system.

Recently, various energy efficiency optimization activities are ongoing globally by integrating conventional grids with ICT (Information and Communication Technology). In this sense, various smart grid projects, which power suppliers and consumers exchange useful informations bilaterally in real time, have been being carried out. The electric vehicle diffusion program is one of the projects and it has been spotlighted because it could resolve green gas problem, fuel economy and tightening environmental regulations. In this paper, the economics of V2G system which consists of electric vehicles and the charging infrastructure is evaluated comparing electric vehicles for V2G with common electric vehicles. Additional benefits of V2G are analyzed in the viewpoint of load leveling, frequency regulation and operation reserve. To find this benefit, electricity sales is modeled mathematically considering depth of discharge, maximum capacity reduction, etc. Benefit and cost analysis methods with the modeling are proposed to decide whether the introduction of V2G systems. Additionally, the methods will contribute to derive the future production and the unit cost of electric vehicle and battery and to get the technical and economic analysis.
