Recently, information systems(IS) outsourcing has become a very important management strategy of implementing IS and many studies on the IS outsourcing approach had been largely performed in the organizations, but it isn't still show how to outsource the IS functions and how to decide quantitative magnitude for judgement. To offer a quantitative decision model that can help practitioners set priority and reap the most benefits from outsourcing, we show outsourcing structure including 3 factors(strategic benefit, economic benefit and technological benefit) and sub-levels which. is different from the Yang and Huang's model. Also, we compute the weight of alternatives using analytic hierarchy process to find a priority of the IS outsourcing. As a result of analysis, we suggest systematic steps and quantitative model to increase the precision of decision making.

As Indonesia is rich in natural resources, nuclear power remains a low priority among energy alternatives. However, Indonesia needs to introduce nuclear power to improve the atmospheric environment and to support sustainable economic growth. This study conducted a two-stage survey of logit-probit and analytic hierarchy process to analyze the perception of Indonesian energy policymakers regarding the introduction of nuclear power, the potential for change, and key decision factors. The analysis confirms that the perception of nuclear power is positive and that the willingness to expand nuclear power can improve if negative conditions, such as underdeveloped technology level, foreign aid and assistance, and safety issues are addressed. In addition, it is confirmed that the policy makers consider political/social and environmental factors to be more important for decision-making. The results of this study can give inplications and be used as a key reference for Indonesia's nuclear power policy

It is important to understand what affects community satisfaction. Because community impacts and participation is a central aspect of fostering local community development, it is important to understand how these processes occur. The study aims to identify the factors influencing community satisfaction and to examine the moderating effects of community participation between community perceived impacts and community satisfaction. Data were collected from 328 usable questionnaires among community residents participating rural development projects in Buyeo and Chungyang county, Chungnam province. Results of a factor analysis yielded four dimensions of community perceived impacts which were negative socio-economic impacts, positive economic impacts, positive environmental impacts, and positive social impacts. Hierarchical regression analysis revealed that negative socio-economic impacts, positive economic impacts, and positive environmental impacts affected significantly for community satisfaction. it reveals that there are moderating effects on community participation of negative socio-economic impacts and positive economic impacts. It was suggested that negative socio-economic impacts, positive economic impacts, and community participation should be considered to implement rural development projects and its policy decision making.

전지전력저장시스템은 부하 평준화, 순동 예비력 확보, 주파수·전압 조정, 신뢰도 향상 및 송변전 설비의 투자지연효과 등의 많은 장점을 가진다. 전지전력저장시스템의 보급을 확산하기 위해서는 수용가 입장에서 본 경제성 평가가 중요하다. 본 논문에서는 기존의 모델을 보완, 개선한 전지전력저장시스템의 경제성 평가 모델을 제안하였다. 제안된 경제성 평가 모델을 한국전력의 부하 조사로부터 얻어진 전형적 수용가인 경공업, 상업, 가정용 수용가에 적용하여 순현재가치, 수익률 등의 경제 척도를 통해 각 수용가의 경제성 타당성을 분석하였다. 이의 결과를 보면 전지전력저장시스템은 특정 수용가 형태(가정 수용가)에 유리하다는 것을 알 수 있었으며, 정부 및 에너지 에이전트는 이의 보급 확산을 위해 세금 혜택, 금융 지원 등의 프로그램을 실행하여야 할 것이다. 본 논문의 결과는 수용가의 투자 의사결정 및 정부 에너지 관련 부서의 정책에 도움이 될 것이다.

This research focus on the economic activity as consumer and producer traits of future customers in the convergence age. We assess level of convergence for digital devices and services respectively by questionnaire survey and interview for 14 professions. And then, for evaluating convergence level and usage of digital services of each respondents, we conducted the questionnaire survey for 343 samples. Findings of our research hold that the group who showed higher level of convergence tends to use the socialized digital services more. Convergence generation were heavy users in appstore on smart-phone and wireless game and more participating. In digital service area, facebook/cyworld, twitter, UCC, portal, internet community in digital service. Convergence generation are global network communication, buying decision making activity, actively opinion expression, prosumer attitude, dependency on digital device, experience based purchase behavior, enthusiastic information sharing.

A model to estimate economic consequence of severe accident provides some measure of the impact on the accident and enables to know the different effects of the accident described as same terms of cost and combined as necessary. Techniques to assess the consequences of accidents in terms of cost have many applications, for instance in examining countermeasure options, as part of either emergency planning or decision making after an accident. In this study, a model to estimate the accident economic consequence is developed appropriate to our country focused on PWR accident costs from a societal viewpoint. Societal costs are estimated by accounting for losses that directly affect the plant licensee, the public, the nuclear industry, or the electric utility industry after PWR accident.

Defense industry as 'a new dynamics of economic growth' policy implies driving policy of defense products' export. The purpose of this study is to suggest suitable strategies to meet with such policy in terms of region and individual nation. The strategies towards advanced region are joint sale strategy for the third countries, extension strategy of trade-off and development strategy of products to exploit niche markets. The strategies towards non-advanced regions are package strategy including exchange of economic development know-how, strengthening strategy of relationships to leading groups in national decision-making processes, exploit strategy of sales market through transfer discard and surplus equipments to other nations, government to government sale strategy towards countries holding low leveled equipment maintaining and management abilities. Finally, successive strategies require leaders' will, active sales diplomacy and active international cooperations of defense industry.

Major problems involved in an electrical utility expansion planning within a time horizon are how to efficiently deal with objectives considering multiple factors and uncertainty. But justification factors in study these days have considered only quantitative factors except qualitative factors. Therefore, the purpose of this paper is to develop a new model for economic evaluation of nuclear power plants through the scoring model with the quantitative and qualitative factors under uncertainty. The quantitative factors use a levelized generation cost method considering time value of money. Especially, the environmental, risk, and safety factors in this paper have been also explained for the rational economic justification of the qualitative factors under uncertainty. This paper not only proposes a new approach method using the scoring model in evaluating economy of the nuclear power plant in the long term, but also provides the more efficient decision making criterion for nuclear power plants under uncertainty.

The integration of nanoparticles into various industries has spurred interest in understanding their impact on logistics and transportation systems. In this study, we investigate the effect of nanoparticles on the economic aspects of railway logistics transport using a mathematical model. By incorporating factors such as transportation costs, time efficiency, and environmental considerations, we aim to assess the overall economic feasibility of integrating nanoparticles into railway logistics operations. Through mathematical modeling and analysis, we explore how the introduction of nanoparticles affects cost-benefit analyses, resource allocation, and decision-making processes within railway logistics. Our findings provide valuable insights into the economic implications of nanoparticle integration in railway transport, offering potential strategies for optimizing logistics operations and enhancing overall efficiency and sustainability.
