This study analyzed the feasibility of custom work service to deal with the imbalance of farm labor supply due to population aging. The economic feasibility analysis is based on the case of Bonghwang-myeon in Naju-si, where the majority of farm work is entrusted to local agricultural cooperative. To assess the project profitability and economic feasibility based on the projected cash flow for the next ten years, Return On Investment (ROI), Net Present Value (NPV), and Internal Rate of Return (IRR) of the projects were calculated. The results showed that ROI is estimated at 13.7%, and NPV and IRR are KRW 1,504,932,000 and 15.6%, respectively, with a discount rate of 4.5%, indicating a good enough profitability. Furthermore, a sensitivity analysis with government support as part of an assumption showed that without the support, NPV turns negative, implying that the project is not profitable, and that government support for at least 30% of the cost is needed to secure the economic feasibility of a project. Hence, to promote agricultural work entrustment, it is necessary for the government to partly support the agricultural machinery and facility costs, which require a considerable amount of initial investment.

In this paper, we analyze the economic ripple effects of technology related to the unmanned aerial vehicle industry by applying industry association analysis. Specifically, the effects of employment creation, value added inducement, sensitivity coefficient, and influence coefficient can be calculated, and implications for the analysis result are presented. As a result, the employment inducement effect was confirmed to be 10.017 persons per 1 billion won of investment. The value added inducement effect was much higher than the other manufacturing industry average (employment inducement coefficient: 2.285, value added inducement coefficient: 0.581) when the 1 won budget was added, resulting in 0.9771 won added value. In the unmanned aerial vehicle industry, the coefficient of sensitivity, which means the front chain effect, is 0.7870, which is lower than the manufacturing average (sensitivity coefficient 1.125), and the coefficient of influence, which means the backward chain effect, is 1.161, which is higher than the manufacturing average (influence coefficient: 1.116). Therefore, it is classified as the final demand manufacturing industry. This means that the unmanned aerial vehicle industry is an industry that is less affected by economic fluctuations and can be interpreted as an industry with a greater economic impact than other sectors. Based on these data, it can be used to establish the R&D investment direction policy of the unmanned aerospace industry.

In recent years, payability of shale gas production has worsened due to oil and gas price declines resulting from sharply increasing shale gas production. Reliable economic evaluation in shale gas development has become important. In this study, Monte Carlo simulation of probabilistic analysis technique was applied to analyze the economic feasibility considering the uncertainty involved in shale gas development. For this, the range of major variables is set and a random number is generated to derive the probability distribution of Net Present Value(NPV) and Internal Rate of Return(IRR). Consequently, we estimated the probability that the feasibility of the project is evaluated to be positive when developing shale gas in the study area. In addition, sensitivity analysis of major parameters affecting economic efficiency in shale gas development was carried out, and the effect of major variables in economic evaluation for commercial production was identified. In the future, this study could be used to make decision for shale gas production by presenting the range of variation of economic index and probability value.

Purpose : The purpose of the study were to describe outcomes of CHP activities, and to evaluate the economic validity of CHP through a cost-benefit analysis. Method : The sample size was 272. Data were collected using a researcher developed questionnaire from November 1999 to March, 2000. Result : The mean age of CHPs was 39.6 (SD-36). In regard to marital status, 90.8% of the respondents were married. 72% of the CHPs had associate degree. Among CHP activities, providing medical services was 50%, followed by home care visits 20% and health promotion services 20%, preventive services 10%. Total costs per month incurred to CHP activities was \3,053,437($2,442.7). Total benefits per month was \6,711,525($5,369.2). Hence, net benefit was calculated as \3,658,089($2,926). Conclusion : Cost-benefit ratio was 2.20, which provides the evidence of the economic viability of CHP program. The result of cost-benefit analysis, however, would more strongly support the economic value of CHP if intangible benefits of CHP activities such as decreases in pain and suffering and increased quality of life, could be counted.

The proposed technical work attempts to compare the two key technologies of power distribution, i.e. direct current (DC) and alternating current (AC) in a fiscal manner. The DC versus AC debate has been around since the earliest days of electric power. Here, at least four types of a low voltage DC (LVDC) distribution are examined as an alternative to the existing medium voltage AC (MVAC) distribution with an economic assessment technique for a project investment. Besides, the sensitivity analysis will be incorporated in the overall economic analysis model to cover uncertainties of the input data. A detailed feasibility study indicates that many of the common benefits claimed for an LVDC distribution will continue to grow more profoundly as it is foreseen to arise with the increased integration of renewable energy sources and the proliferation of energy storage associated with the enhanced utilization of uninterruptible power supply (UPS) systems.

Recently on Value Engineering(VE) and Life Cycle Cost(LCC) social interests is increasing. The government Turn Key, BTL projects and public works projects, such as VE and LCC Analysis on the value and economic analysis is mandatory. And accordingly the VE and LCC analysis is underway for the various studies. However, there is a problem existing in the LCC analysis. Worth the cost varies according to the flow of time. However, the real interest rate during the LCC analysis of buildings in calculation time for interest rates and inflation are not considering the value of the flow. In other words, a few years using the average value of the deterministic analysis method has been adopted. These costs for the definitive analysis of the cost of an uncertain future, unforeseen changes resulting hazardous value. In this study of the last 15 years interest rates and inflation targeting by using Monte-Carlo Simulation is to perform probabilistic analysis. This potential to overcome uncertainties of the cost of building a more scientific and LCC Estimation of the probability value of the real interest rate is presented.

The purpose of this study was to compare the attitudes and behaviors toward money among college students after and before IMF economic crisis. The subject of investigation consists of 389 students in the year of 1995 and 112 students in the year of 2000 in Wonkwang university. The major findings are as follows: 1) The exploratory factor analysis of money attitudes and behaviors scale drew four factors such as; power, obsession, money management and pleasure. 2) Male students have a tendency more likely than females not only to look upon money as power but also to have an obsession before IMF economic crisis. But gender differences were disappeared after. 3) In comparison of the before and after IMF economic crisis, the behavior value in reference to money is generally increased. The social power and the cognitive attitude like an obsessional increased smaller than that of a practical such as money management or pleasure. The pleasure is raised the largest. 4) The level of attitudes and behavior for money management is raised the most for female students while, the value of the pleasure has the greatest increase for male students rate.
