This study tried to find out alternatives adjusting basic fare using customer survey. But it merely verified that train fare decision is made by government's role and market status. Also, it has a limitation deciding resonable fare of KTX that average cost and marginal cost calculation is impossible because Korean National Railroad does not follow 'Activity Based Costing'. It is rational fare decision that performing survey to railroad experts and general customers, and compare two results. Summarizing results of this study, 1. The hypothesis 'Experts' perceived fare level of KTX is higher than that of general customer. 'is carried. It suggests that following experts' opinion with general customer's is very rational method to decide fare level. 2. The hypothesis 'Experts expect lower level of fare discount rate than general customer.' is carried. 3. It is hard to decide priority among many kinds of discount for difference of two group's preference. However, following recent research project is maximized by discounting fare 30$\%$ on 40$\%$ of total passenger and expand number of discount kinds step by step are desirable.

This study investigates effcts of HMO internal structural arrangements on performance, specially cost reduction measured by hospitalization rate. This study formulates formalization, centralization measured by decision-making participation, differentiation, and coordination as structural factors, considering coordination as an intermediate factor between the rest of structural factors and hospitalization rate. The commonly used HMO types is assumed not effective in explaining performance differences. For the empirical test, I use bootstrap regression analyses with 48 HMOs. The results of the analyses show that HMO types fail to explain differences in hospitalization rate. However, dicision-making participation and differention effectively reduce hospiatalization rate, while frmalization increases hospitalization rate and coordination has nonessential effect on hospitalization rate. And, formalization and decision-making participation positively contribute to achieve coordination in HMO. These findings suggest that the theoretical framework derived from rational-citingency theory of formal organization better explains performance differences of HMOs than HMO types.

The aim of this paper is to explore various ways to utilize critical thinking in engineering education. To this end, this paper, in the light of the relationship between critical thinking and the program learning performance of ABEEK, reviews engineering design education, engineering ethics education, and engineering communication education, which are major areas where critical thinking can be utilized in engineering education. As a result, it was confirmed that critical thinking skills, especially the elements and criteria of critical thinking, can contribute to the creative problem-solving process in engineering design education, the rational decision-making process in engineering ethics education, and the effective communication process in engineering communication education.

This paper is aimed at proposing a new framework to predict decision performance, by Investigating decision maker's cognitive resonance. We assume that every decision maker has two kinds of schema­emotional schema and rational schema. Cognitive resonance is believed to have a close relationship with the two schemata and decision performance. In literature on decision performance there is no study' seeking relationship among the two schemata ana cognitive resonance. Therefore, our research purposes are twofold: (1) to provide a theoretical basis for the proposed framework describing the causal relationships among two schemata, cognitive resonance, and decision Performance, and (2) to empirically prove its validity applying to. Internet shopping Situation. Based on the questionnaires from 13S- respondents, we used a second order confirmatory factor analysis (CFA) to extract valid constructs, and structural equation model (SEM) to calculate path coefficients and prove the statistical validity of our proposed research model. Experimental results supported our research model with some further research issues.

현장에서 직접 대상자의 가정을 방문하여 요구사정에서부터 중재, 평가에 이르기까지 간호제공의 전 과정을 수행해야 하는 방문간호사의 업무수행 능력을 제고의 관점에서 의사결정 유형과 셀프리더십 그리고 의사소통 능력간의 관련성을 분석하였다. 방문간호사들의 의사결정 유형과 의사소통 능력과 셀프리더십은 모두 상관관계가 있었으며 서로 유기적인 관계가 있음을 확인하였다. 방문간호사의 의사결정 유형은 합리적 유형이 가장 많은 것으로 나타났으며, 이와 관련하여 셀프리더십 정도와 의사소통 능력 측면에서도 합리적 의사결정 유형에서 가장 높은 점수를 나타냈다. 합리적 의사결정 유형은 의사결정 유형 중 가장 바람직한 것으로 논의되어 온 바 방문간호사가 높은 문제해결 능력을 가지고 있음을 실증적으로 보여준 사례로 해석할 수 있다.

국방 무기체계 연구개발 과정에서 관련 규정이나 지침에 명시되지 않았지만, 연구개발 주관기관 내부적으로도 합리적인 대안 선택의 문제가 많이 발생한다. 대안 선택에 있어서 합리적인 과정이 적용되지 않으면 사업진행에 차질을 초래할 수 있으며, 이로 인해 사업기간 연장이나 추가 자원이 투입되는 상황도 발생된다. 특히 국내 미사일 연구개발 시 시험평가를 위한 많은 의사결정 과제들이 도출되며, 대표적인 것 중의 하나가 시험장 선정의 문제이다. 대안이 되는 시험장의 우선순위만 판단해야 한다면 델파이 기법(Delphi Method)이나 분석적계층과정(Analytic Hirarchy Process)을 활용할 수 있지만, 비용의 투입요소가 고려된다면 자료포락분석(Data Envelopment Analysis) 더 적합하다. 본 연구에서는 미사일 시험 시 발생되는 다양한 의사결정의 문제들을 염출해 보고, 이를 합리적으로 해결할 수 있는 의사결정의 방법이 제시된다. 제시된 의사결정의 프레임워크(Framework)는 국외 시험장을 선정하는 문제와 연관하여 모의 사례연구(Simulated Case Study)로 적용 과정이 연구된다.

In the cut-throat competitive environment of business, large-scale IS investment is becoming inevitable strategic necessity for gaining competitive advantage. However. it bears great deal of risk over all the associated processes so that the investment decisions need to be taken in a greatly careful manner. Nonetheless, Korean organizations are prominently showing risk taking behaviors regarding major is investment, in terms of system downsizing. Although decision theory argues decision makers' rational choice of options through the assessment of risk and benefit, the notable trend toward system downsizing in Korea defies common understandings on IS project risk. Furthermore, it encourages us to investigate many impenetrable characteristics underlying organizational risk taking decisions with IS investment. We found out that there is Significant effect of IS decision makers' risk propensity when they make system downsizing decisions. Moreover. we Identified that IS decision makers do not get a strong pressure of cost savings and have tendencies to mimic competitor's decisions.

Objectives : This study was performed to investigate the relationship between decision making style and learning style according to Sasang constitution. Methods : The subjects were 213 nursing students of K college in Jeonbuk, and the period of data gathering was limited from 1 Sep. 2009 to 7 Sep. 2009. The instrument tools included QSCC II, decision making style, and learning style. The collected data were analyzed by SPSS-PC programme. Results : 1. Decision making style: Soeumin group had significantly high score in rational score compared with Soyangin(F=7.174 p=.001), and in dependent score compared with Taeumin and Soyangin (F=3.414, p=.035). 2. Learning style: Soyangin group had significantly high score in cooperation score compared with Taeumin(F=5.688 p=.004), and Taeumin group had significantly high score in emulous score compared with Soeumin and Soyangin (F=.148, p=.002). Conclusions : In conclusion, it was found that decision making style and learning style are significantly different according to Sasang constitution. Therefore, these results suggest that nursing educational program needs to be developed considering Sasang constitution.

In this study, the multi-criteria decision-making model based on Quality Function Deployment Method is proposed. Multicriteria decision-making is an attempt to link QFD method with the TOPSIS. By this effort, a model that makes client's decision-making more rational and objective in design phase is suggested. The multi-criteria decisionmaking model confirming to the Owner's requirements will improve the productivity of the construction industry and the satisfaction of the customer. Further study extending the range of the requirements, not only the Owner's requirement will be necessary to cover the various factors as much as possible. And then, finally as a flexible platform to achieve a sustainable quality management, web-based multi-criteria decision-making model can be utilized by the relevant stakeholders simultaneously with the feed-back and sharing the necessary informations.
