  • 가축전염병 중 하나인 구제역의 경우 정보의 초동 대응 미흡 등으로 전국적으로 확산되는 피해를 초래하였다. 이를 해결하기 위해 국가에서는 가축이력에 대한 체계적인 관리를 마련하기 위하여 데이터를 구축하였으며, 2002년도부터 추진되어 현재 웹 기반의 가축전염병 발생 통계 시스템(AIMS)이 운영하고 있다. 이는 사용자가 원하는 기간에 해당 축종의 형태에 따른 질병을 선택하면 지역별로 가축전염병 발생 통계 현황이 텍스트 기반으로 제공하고 있다. 하지만 이 같은 경우 시각적으로 공간적인 위치정보를 즉각적으로 파악할 수 없기 때문에 정보를 효과적으로 전달하기 어렵고, 의사결정을 내리고자 할 때 사용자가 원하는 정보를 다차원적으로 지원하지 못하는 한계가 있다. 이 연구에서는 오픈소스 기반의 SOLAP(Spatial On-Line Analytical Processing) 기술을 적용하여 여러 형태의 데이터를 다각적인 방법으로 분석하고, 최종적으로 나온 결과를 공간정보와 통합하여 지도상에 시각적으로 전달되도록 표현하였다.

  • The paper is to analyze multi-attributes for expanding new renewable energy in agricultural sectors which have environmental, technical, economic, and social factors consisting of 15 attributes which have both positive and negative impacts. We applied the analytic hierarchy process (AHP) to data from opinion polls. As a result of the AHP survey, the overall results indicate that the respondents more weight on economical factor than environmental, technical, and social factors for expanding new renewable energy. At the lowest level, a comparison of individual 15 attributes within three factors shows that fixed cost highest in multi-attributes, followed by operating cost, technical superiority. To achieve the public acceptance about expanding new renewable energy in agricultural sectors, the policy-makers should take all relevant factors into account through the decision-making process by the public opinions.

  • Purpose - The purpose of this research is to provide insights that can be used for deliberate decision making around challenging big data investments by measuring the economic value of such big data implementations. Research design, data, and methodology - We perform empirical research through an event study. To this end, we measure actual abnormal returns of companies that are triggered by their investment announcements in big data, or firm size information, during the three-year research period. The research period targets a timeframe after the introduction of big data at Korean firms listed on the Korea stock markets. Results - Our empirical findings discover that on the event day and the day after, the abnormal returns are significantly positive. In addition, our further examination of firm size impacts on the abnormal returns does not show any evidence of an effect. Conclusions - Our research suggests that an event study can be useful as an alternative means to measure the return on investment (ROI) for big data in order to lessen the difficulties or decision making around big data investments.

  • The purpose of Environmental Impact Statement (EIS) is an integral component of decisions on proposed plans, projects, and actions. Adapted from the National Environmental Policy Act(NEPA, 1969) environmental impact statement in Korea has aimed to analyse and prepare the mitigation in the process of big scale development and major industrial planning. During the past 19 years EIS has played the central role for the environmental issues in the process of economic development. Nevertheless EIS act needs some modification in the system as well as in the contents of evaluation process. EIS should be served as decision-making process by assessing environmental issues in the beginning stage of proposed actions. Other consideration was suggested to make EIS system better used for environment conservation.

  • Risk assessment is useful tool making good decisions on the risks of certain hazardous com-pound and suggests safe margin through scientific process using toxicological data, statistical tool, exposure value and relevant variants. The goal of risk management is to protect the public health from hazardous compound based on result of risk assessment having reality. For the suggestion of exact man-aging information, risk assessment must be designed to represent a "plausible estimate" of the exposure to the individuals and to minimize uncertainty. Risk assessment methodology and knowledge are expected to change more rapidly than before and up-to-date methodology should be applied in regulatory aspects through the Agency. For the useful application of risk assessment, the communication between the risk assessor and the risk manager is needed before the initiation of the risk assessment and upon its completion. Generally, the risk assessment itself as a practical tool in the regulatory decision making process would be regarded with social economic impact.ic impact.

  • In this research, we investigate the method to support decision making of researcher when they estimate the safety on the subway using AHP of Saaty. To apply this technique, we apply to subway system. The AHP suggested by Saaty in 1971 is a tool to support a decision-making including the personal opinion and intuition, and it is easier than other method. Then, it has an advantage that control the complex object having multiple criteria simply. And we suggest the eight stage of accident type and the five criteria that must meet. Based on AHP, we concluded a safety in subway is more important factor than any other factors including economic points of view.

  • This paper seeks to measure the monetary value of technical development in the deep seabed manganese nodule mining by applying the compound option model (COM). The COM is appropriate for the project in terms of its decision-making structure and embedded uncertainty. The estimation results show that the deep seabed mining project has more economic potential than shown by the previously obtained results from the discounted cash flow (DCF) analysis. In addition, it is reasonable to invest in the project taking the various uncertainty factors into consideration, because the ratio of the value to the cost of the project is far higher than one. This information can be utilized in national ocean policy decision-making.

  • Recently, the strategy of the age of limitless competition for existence of manufacturing company appears for the enhancement of productivity through the automatic system, the reduction for the cost for standardization and the decision making process for the information system. Especially the critical success factors in manufacturing company can be summarized for the establishment of production visibility through the production management, material & work-in-process management, the establish of the flexible manufacturing system for the changed order priority and the establish of the quality system for improvement of product and process quality. The existing production management systems supply only simple information about production results on real time, can delay quick decision making. And it can prevent acquiring the information about various customer needs and the communication problems with other systems. In this paper, it will show MES system, a solution for the problems of existing production management systems. And through a case study of D company, it will reveal improvement effect on shipment error using MES system and economic analysis for MES itself.

  • The environmental problem come because the demage cost of environmental pollution is not properly reflected in market price. The government regulations for market is justified to solve the problem. The policy needs a close analysis of environmental, economical effect for the point of time, methods, rational decision making of the government regulations. Especially, we need to assume and analyze about social expenses by environmental pollution and policy execution. The cost-benefit analysis about environmental pollution is used to support decision making. The value of benefit about damage by environmental pollution or about improvement changes a monetary unit through the cost-benefit analysis. The working like this is said environmental material valuation or measuring valuation. This work is studied about looking for proper analysis model to apply our environmental materials.

  • Since Cost Based Pool markets has been continued to power markets, Genco. needs economic analysis about investment in power plants. Particularly most Private Genco.s have presently a construction plan about LNG combined cycle thermal power plants. In this paper, we propose a economic analysis method of LNG combined cycle thermal power plants using Economic Dispatch and Optimal Power Flow in CBP markets. Also we develope computation model using it for decision making to build a plant. This method can consider a variation of power facility like power plants and transmission lines in CBP markets. Finally, this dissertation provides a relevant case study to confirm the effect of cost factor to economical efficiency.
