일반적으로 투자자들은 높은 수익을 얻기를 바라는 성향 그리고 위험기피적 성향을 가지고 있는 것으로 받아들여진다. 그러나 투자자들이 갖는 이러한 대표적인 두가지 성향은 현실에서 직면하는 투자대안의 경우에 서로 상층(trade-off)하는 것이 일반적이며, 따라서 그러한 상충관계를 서로 다른 수준으로 포함하고 있는 대안들 중에서 어떤 것을 선택하는 때에 투자자의 선호체계가 중요하게 작용한다. 그런데 많은 경우 투자자들은 그러한 상충관계에 직면했을 때, 커다란 손실의 가능성을 포함하는 대안이 아니라면 약간 낮은 평균수익이 에상되더라도 높은 수익의 가능성이 상대적으로 높은 대안을 선호하는 것으로 나타났다. 따라서 본 연구에서는 약간 낮은 평균수익이 예상되더라도 높은 수익의 가능성이 상대적으로 높은 대안 즉, 대안 수익의 분포가 우향왜곡된(skewed positively)대안을 선호하는 투자자의 성향을 포함시킬 수 있는 방법을 모색하였다.

The purpose of this study is to suggest a model for evaluation of a risk based value index for modular design alternatives in plant construction projects. Accordingly, 1) Setting the basic project cost and the scope to apply the module, 2) Evaluating the importance, easiness, and effectiveness index for Engineering, Procurement, Fabrication, transportation, and construction work, 3) Estimating the total project cost by analyzing the risk reserve Step, 4) Comparing the effectiveness index and total project cost for each modular design alternative, it was composed of the steps of deriving RVI. To verify such a model, Plan-A, which applied a module to one process, and Plan-B, which applied a module to three processes, were composed to evaluate RVI.

Nuclear power has been an attractive energy efficient and to the pressure with the climate change despite of its risks. There are safety, security, and environmental concerns with the nuclear radiation, but the techno-optimism forms the mainstream by experts and the state to be able to control and manage the risks yet occurred. The disastrous Chernobyl and Fukushima nuclear accidents brought about alternative action and thought including renewable energy expansion, efficient energy delivery and use, and enhancing stewardship to environmental carrying capacity. More significant alternative movement is sought by victims of nuclear radiation, technicians, and the general public who realized the pitfalls of expert and state centered policy formation. These laypersons become counter-expertise competent in recognizing local contamination and considering the risks and emotions seriously affecting peoples' everyday lives. They play important roles in the construction and legitimation of alternative knowledge about nuclear power widely realized across regions.

Three studies re-examined Shafer's(1993) response compatibility hypothesis in decision making. This hypothesis proposes that participants choose or reject an option when its features are compatible with either a selection or a rejection response. By changing the description of options into sentences and by the prior presentation of either a selection or a rejection question, we obtained results fairly consistent with the predictions of the response compatibility hypothesis. Based on the analysis of both previous and present results, we discussed the importance of preference elicitation methods when constructing options. Our results were compared to those of recent studies.

This study regards to a method how to select the optimized earth retaining technology among four target technologies which are applied to underground construction work by analyzing relative weight values of major influence factors. In this study, major affected zone and influence factors are analyzed through questionnaire survey to select a suitable earth retaining technology for downtown area, and an optimized earth retaining technology is proposed by using the matrix analysis based on them. Also, by systematically analyzing the weight values and methods of alternatives selection through consideration the importance of alternatives evaluation criteria, the importance of affected zones is evaluated to determine the optimized alternative. It is concluded that when performing the analysis to select the earth retaining technology which should consider a variety of constraints, the convergence with information processing technology in the field of IT is effective to analyze and optimize many constraints.

요구공학의 궁극적인 목표는 이해당사들의 요구사항을 수용하고, 이를 적절히 설계 및 반영하여 프로젝트를 성공하는데 있어 그 목표를 두고 있다. 그러나 일반적으로 수렴된 요구사항들은 상호간에 충돌이 발생하거나, 합리적인 대안을 이끄는데 있어 많은 문제점을 드러낸다. 따라서, 이를 극복하기 위해 다양한 대안들이 제시되고 있다. 본 논문에서는 이해당사자 상호간의 영향력을 분석(정준상관분석)하여, 중요도 평가를 위한 척도를 만들고, 이를 계층분석적 의사결정방법의 초기 단계에 적용하여 우선순위에 의거하여, 최종 대안을 선택하게 될 것이다. 이를 마지막으로는 위의 과정을 WinWin 협의 모델에 적용하고자 한다.

이동전화시장에 대한 규제여부를 논의할 때 가장 중요한 요인으로 이동전화시장의 경쟁상황을 들고 있다. 대부분의 이동망 비규제를 주장하는 측의 논리는 이동전화시장은 복수사업자체제로 치열한 경쟁이 전개되고 있기 때문에 고정망에서와 같은 강력한 규제가 대칭적으로 적용되어서는 안된다는 점을 강조하고 있다. 본 고에서는 이러한 주장의 타당성을 검토하고 합리적인 이동망 시장 규제대안을 모색해보기 위해서 이동전화 시장구조를 살펴보고 세분화된 이동전화 시장 내에서의 경쟁상황을 검토하였다. 아울러 본 고에서는 이러한 분석을 바탕으로 세분화된 이동전화 시장상황에 적합한 정책 및 규제 대안을 제안하였다.

The objective of this study is to evaluate the effectiveness of new operation system for port container terminals. We assumed that the operation system of container terminal consists of monitorig ＆ control system, operation system, planning system, and information technology, and we selected total 19 technology alternatives. Through the results of questionnaire and interview received from field expert, we established the evaluation model and analyze the productivity improvement by estimating the weight and the priority of productivity for operation system. From the developed model, we provide useful implications to introduce new technologies of operation system for domestic container terminals.
