  • Recently, the continuing operation of nuclear power plants has become a major controversial issue in Korea. Whether to continue to operate nuclear power plants is a matter to be determined considering many factors including social and political factors as well as economic factors. But in this paper we concentrate only on the economic factors to make an optimum decision on operating nuclear power plants. Decisions should be based on forecasts of plant accident risks and large and small accident data from power plants. We outline the structure of a decision model that incorporate accident risks. We formulate to decide whether to shutdown permanently, shutdown temporarily for maintenance, or to operate one period of time and then periodically repeat the analysis and decision process with additional information about new costs and risks. The forecasting model to predict nuclear power plant accidents is incorporated for an improved decision making. First, we build a one-period decision model and extend this theory to a multi-period model. In this paper we utilize influence diagrams as well as decision trees for modeling. And bayesian statistical approach is utilized. Many of the parameter values in this model may be set fairly subjective by decision makers. Once the parameter values have been determined, the model will be able to present the optimal decision according to that value.

  • 우수 인재들이 진로를 결정하는 결정적 요인은 무엇일까? 이 연구는 이 물음에서 출발하여 과학영재 대학생을 위한 진로결정 요인 척도를 개발하고자 하였다. 이를 위해 과학영재/인재, 과학자의 진로 결정과 관련된 문헌고찰을 통하여 개인적성 및 자아실현, 경제적 가치, 일과 여과, 가족의 영향, 부모/교사의 권유, 학창시절 과학활동 경험의 6가지 요인을 바탕으로 총 26문항의 진로결정 요인 척도를 개발하였다. 이를 위해 수도권 소재 대학의 이공계 대학생 153명을 대상으로 예비연구를 실시하였으며, 본 검사는 국내외 대통령 장학생 264명과 대학부설 과학영재교육원을 수료한 대학생 93명 등 총 510명을 대상으로 실시하였다. 연구결과, 측정모형 적합도는 ${\chi}^2$=645.157 (df=279, p=.00), TLI=.924, CFI=.935, RMSEA=.061로 나타나 대부분의 적합도 지수는 수용기준을 충족하는 것으로 나타났으며, 대학생 과학영재들의 진로 결정 요인을 측정하는 타당한 도구임을 확인할 수 있었다. 각 하위요인의 내적합치도인 Cronbach의 ${\alpha}$ 역시 개인적성 및 자아실현 .82, 경제적 가치 .94, 일과 여과 .84, 가족의 영향 .88, 부모/교사의 권유 .79, 학창시절 과학활동 경험 .79로 양호한 것으로 나타나 개발된 척도가 우리나라 대학생 과학영재들의 진로결정요인을 측정하는 타당하고 신뢰로운 도구임을 알 수 있었다. 또한 개발된 척도는 진로분야의 이론적 틀을 구성하고 과학영재의 진로지도 및 진로상담을 돕기 위한 기초연구로 활용 될 수 있을 것으로 사료된다.

  • R&D is a foundation for new business chance and productivity improvement leading to enormous expense and a long-term multi-step process. During the R&D process, decision-makers are confused due to the various future uncertainties that influence economic and technical success of the R&D projects. For these reasons, several decision-making models for R&D project investment have been suggested; they are based on traditional methods such as Discounted Cash Flow (DCF), Decision Tree Analysis (DTA) and Real Option Analysis (ROA) or some fusion forms of the traditional methods. However, almost of the models have constraints in practical use owing to limits on application, procedural complexity and incomplete reflection of the uncertainties. In this study, to make the constraints minimized, we propose a new model named Real Option Decision Tree Model which is a conceptual combination form of ROA and DTA. With this model, it is possible for the decision-makers to simulate the project value applying the uncertainties onto the decision making nodes.

  • In this study, an integrated economic analysis model to analyze the new telecommunication services is developed. This model considers both the technological and managerial aspests altogether with respect to the profit and public benefit criteria. To encounter the various dynamically changing environments and evaluation criteria, multiple criteria decision making (MCDM)techniques are employed. The model consists of three stages; The first stage surveys related formal or informal data, generates analysis alternatives, and performs acceptabillty test in view of marketing. The second stage generates executive alternatives for each acceptable analysis alternative and checks the executionability in view of telecommunication technologies. The third stage performs the final integrated economic analysis including the profitability analysis. This study offers a basis for the future development of decision support system or expert system on the economic analysis of the new telecommunication services.

  • This study attempts to utilize the economic efficiency analysis results focused on the break-even point as an indicator for the decision making of commanders and staff. We suggested a method of determining economic life by utilizing logistics information system and commercial program Minitab with a focus on the equipment's operational environment and performance data, whereas previously the equipment's retirement period was simply determined by the current equipment prices and sustainable period.

  • Purpose: It suggests that making a policy and strategies in a way of AI and its impact of commercialization on economic efficiency, social custom ethics. Research design, data, and methodology: The paper has analyzed the data based on the proposed model when derived as AI vs. FI job, etc. It is very different for each professional evaluation, which is artificial intelligence or robot job. One concept case was selected as a substitute job, with a relatively low level of occupation ability, such as direct labors, easily replaced. By the induction data has resulted in modeling. Results: The paper suggests that AI at high level become something how to make real decisions on ethical value modeling. Through physical simulation with the deduction data, it can be tuned to design and control what has not been solved, from human senses to climate. Conclusion: For the exploiting of new AI decision-making jobs in markets, the deduction data is possible to prove to AI's Decision-making that the percentage who can easily have different leadership as is different for each person. what is generated by some information silos may be applied to occupation societies. The empirical results indicate the deduction data that if AI determines ethical decisions (VC) for that modifications, it may replace future jobs.

  • New Zealand appears to be a water rich country; however there are considerable water allocation issues. Mostly these revolve around balancing environmental concerns with economic development. The largest economic sector is agriculture which currently utilizes around 80% of the allocated water and has considerable potential to increase in size. The resource management framework that New Zealand has developed over the past twenty years revolves around local decision-making and sustainable management principles. As the demands for water have grown there has been growing concern that this framework is inadequate to deal with the issues of declining water quantity and quality through agricultural intensification. In Canterbury, the region with the highest water allocation and demand, a new approach is being trialed. The Canterbury Water Management Strategy (CWMS) recognizes the need for: ecological restoration for past damage; infrastructure development for increased irrigation; and the need to link infrastructure with more efficient use of water by both existing and new water users. These three elements are recognized as having equal value. The CWMS builds on the local decision-making concept but is deliberately aimed at consensus building in order to remove expensive and adversarial resource management hearings. It is practical enough to recognize that economic development is needed but that it need not proceed in conflict with the environment, but rather can be a means towards environmental improvement.
