The purpose of this study is to empirically analyze the rational decision-making process and perception differences of housing transactions in the market environment. It was designed through an analysis of the factors influencing housing sales based on the rational behavior theory model. Objective evidence was provided for the impact factors affecting the attitude towards housing sales, with the spouse and children being identified as significant influencers. Additionally, children and friends were found to have an impact on subjective norms related to housing sales, especially for unmarried individuals under 40 years of age and those with low income, who were found to be more influenced by their parents. It was also discovered that the influence of these factors varied based on age and income levels. Younger individuals tended to rely more on their parents or friends, while those with high incomes showed stronger willingness to purchase homes. The presence of beneficial infrastructure for children was found to directly influence the decision to purchase a home. The study also provided objective evidence that the decision to purchase a home is influenced not only by economic factors but also by continuous encouragement and information from those around the buyer. These findings demonstrate the importance of the influence of close acquaintances in the rational decision-making process of home buyers. However, this study only investigated a limited portion of the factors influencing housing sales, as the market is affected by a variety of financial and governmental policies. Therefore, future research should consider various complex factors simultaneously when analyzing the influence of housing sales.

Purpose - The purpose of this study is to provide a formalized process of decision making for companies or organizations that need to make various decisions in the age of uncertainty. Therefore, this study aimed to proposes a strategic decision-making approach citing the relatively easily accessible using IPA(important-performance analysis) and SWOT/AHP analysis. Research design, data, and methodology - To be specific, the first step is to derive necessary attributes and conduct IPA. The second step is to subdivide the IPA results into internal strength and weakness factors and the external opportunity and threat factors, hierarchize those factors, and weight them accordingly. The third step is to build a causality model to propose a method of supporting a rational decision making. Results - The foregoing approach seems to facilitate the diversification of decision-making strategies by helping businesses or organizations to measure and analyze the attributes needed for certain decisions. Additionally, the perceived importance and satisfaction (or achievement) usage of those derived attributes can be used as the reference data for SWOT/AHP analysis. Conclusions - The proposed stepwise approach is applicable to businesses or organizations in need of making stepwise decisions in line with their retained competencies in comparison to conventional or intuitive decision-making practices.

On this research, we classified Korean consumers into several comsumer groups based on the different decision-making process they endorse, and then investigated the difference among these consumer groups in frequency, expenditure, satisfaction in using different types of retail stores. For this research, we have surveyed consumers dwelling in Seoul and in near-Seoul areas in 2004. The following is the summary of the main results. First, 'enjoy shopping' group showed a high expenditure rate in department store shopping and internet shopping, whereas 'impulsive decision' group more frequently visited traditional market places, 'fashion pursuing' group and 'enjoy shopping' group visited department stores more frequently than traditional market places. Second, 'impulsive decision' group assessed that the traditional market place offers better price and quality. Also 'impulsive decision' group and 'enjoy shopping' group assessed positively on the AS provided by department stores, and assessed negatively on the AS provided by internet shopping malls. Finally, 'fashion pursuer' group preferred buying foods from traditional market places, while 'brand seeker' group and 'fashion pursuer' group preferred buying clothes from discount stores. While 'enjoy shopping' group showed a high preference in buying clothes in department stores, 'rational decision-making' group showed a low preference in buying clothes in department stores.

본 논문의 목적은 지상작전 시 피아간 상대적 전투력을 분석하는데 전문가 시스템을 이용하는 방안을 제시하는 것이다. 상대적 전투력 분석은 지휘관 및 참모들이 부대를 어떻게 운용할 것인가에 대한 방향을 설정할 수 있기 때문에, 그 절차는 신속하고 이성적인 의사결정의 과정을 필요로 한다. 여러 애플리케이션들이 탑재될 수 있는 전술정보통신체계가 10년 동안 개발되고 있지만, 상대적 전투력 분석의 절차는 의사결정에 관여한 일부인원들에 의해 수작업으로 진행되어왔다. 본 연구에서는 이론적으로 3가지 상대적 전투력 분석방법을 고찰하고 이를 시스템에 지식(Knowledge)롤 사용될 수 있도록 수치적으로 표현하고, 유형뿐만 아니라 무형의 전투력도 지식에 포함될 수 있는 방안이 연구되었다. 기존의 대대급 전투력 지수와 수치적으로 표현된 지식을 이용하여 상대적 전투력 분석을 위한 전문가 시스템은 EXSYS Corvid로 구현되었다. 의사결정의 오류를 줄이고 빠른 의사결정을 가능하게 하며 유형뿐만 아니라 무형의 전투력까지 의사결정에 반영할 수 있을 것으로 기대된다. 향후에는 전투력 분석뿐만 아니라 인사분야나 정보 분석 분야에도 전문가 시스템을 도입하는 방안이 연구되어 객관적이고 합리적인 군 의사결정체계에 기여해야 한다.

본 논문은 이성적 정보와 감성적 정보에 대해 어떠한 정보 유형이 광고소구의 관점에서 더 효과적인가를 반응시간과 재인 측면에서 검증함과 동시에, 정보의 유형별로 뇌 기능 상의 관계를 fMRI를 이용하여 분석하여 정보유형별 인지처리 상의 차이를 설명하고자 하였다. 이를 위해 두 가지 실험을 수행하였는데, 첫 번째 실험은 두 종류의 자극 유형에 해당하는 광고카피 - 이성에 소구하는 자극과 감성에 소구하는 자극 - 에 대해 어떠한 유형에 해당하는지를 피실험자가 결정하게 하는 과제를 수행하게 하였으며, 자극의 제시로부터 소구 형태를 판단하기까지 소요되는 반응시간의 측정을 통해 각 자극 유형별 효과를 측정하고, 이 때 활성화되는 뇌 영역을 분석하여 인지처리 상의 기능을 비교하였다. 두번째 실험은 자극 유형별로 재인효과를 측정하고, 이 때 활성화되는 뇌 기능 영역 간의 차이를 분석하여 재인 시의 인지처리 상의 기능을 비교하였다. 이러한 실험연구를 통한 결과를 요약하면 다음과 같다. 첫째, 반응시간의 측면에서 감성적 자극에 대한 반응시간이 이성적 자극에 대한 반응시간보다 빠르게 이루어 졌고, 재인 측면에서는 이성적 자극에 대한 기억의 효과가 감성적 자극에 대한 기억보다 높게 나타났다. 둘째, fMRI를 이용한 뇌 기능상의 특징을 보면 이성적 자극의 경우 상대적으로 활성화의 수준이 높은 뇌 영역들은 행동 조정 혹은 작업 기억과 연계된 곳이었다. 반면, 감성적 자극의 경우 상대적으로 활성화의 수준이 높은 뇌 영역은 언어처리와 연계된 곳이었다. 본 연구를 통하여 이성적 자극과 감성적 자극의 소구 효과가 다름을 확인할 수 있었고, 각 소구 형태별로 뇌 기능상의 인지적 차이를 확인할 수 있었다.

The purpose of this study is to examine negative IT performances produced by irrational fashion-mimic IT investments in firms. Since most studies have been carried out on the assumption of rational investment decisions, many of them have revealed positive investment process and performances in firms. However, fashion-mimic investments to follow the paths of market leaders rather than rational investment decisions have been of frequent occurrence in many firms. This study divided types of mimic investments into subgroups where one subgroup has fashion-mimic properties and the other subgroup retains rational-mimic properties. We compared differences in performance of these subgroups to investigate effects of irrational investments in IT projects. The results indicated that there are differences in performance between fashion-mimic and rational-mimic investments. Additional analysis also revealed differences in performance at the presence of CEO control in the case of fashion-mimic investment subgroup.

A risk-informed regulatory approach implies that risk insights be used as supplement of deterministic information for safety decision-making purposes. In this view, the use of risk assessment techniques is expected to lead to improved safety and a more rational allocation of the limited resources available. On the other hand, it is recognized that uncertainties affect both the deterministic safety analyses and the risk assessments. In order for the risk-informed decision making process to be effective, the adequate representation and treatment of such uncertainties is mandatory. In this paper, the risk-informed regulatory framework is considered under the focus of the uncertainty issue. Traditionally, probability theory has provided the language and mathematics for the representation and treatment of uncertainty. More recently, other mathematical structures have been introduced. In particular, the Dempster-Shafer theory of evidence is here illustrated as a generalized framework encompassing probability theory and possibility theory. The special case of probability theory is only addressed as term of comparison, given that it is a well known subject. On the other hand, the special case of possibility theory is amply illustrated. An example of the combination of probability and possibility for treating the uncertainty in the parameters of an event tree is illustrated.

TOPSIS(Technique for Order Preference by Similarity to Ideal Solution)는 상충되는 다수의 속성이 존재하는 상황에서 의사결정이 요구되는 다속성 의사결정법(Multi Attribute Decision Making) 중 하나이다. 이는 선택된 대체안이 최선의 이상적 대체안으로부터 가장 가까운 거리에 위치해야 하고, 동시에 부정적으로 이상적인 대체안으로부터는 가장 멀리 위치해야 한다는 논리에 입각한 의사결정 기법이다. TOPSIS 는 최소화와 최대화가 공존하는 다목적함수 형상 최적설계에 적용이 가능하다. 본 연구에서는 TOPSIS 와 베지어 곡선(Rational Bezier Curve)을 적용하여 CRT(Cathode Ray Tubes) 후면유리의 다중목적 형상최적설계를 수행하였다. 무게와 1 차 주응력의 두 가지 다중목적 함수를 최적화하기 위하여, 다중목적 함수의 성능지표를 TOPSIS 의 상대적 근접도로 정의하고 이를 반응표면모델로 구성하여 다중목적 형상최적설계가 가능한 방법론을 제안하였다. 이를 통해 하나의 최적해가 아닌 최적해의 군이 선정되어, 무게와 주응력 최적해의 모순관계를 확인하면서 다양한 설계요구 스펙을 만족시켜줄 수 있는 방안을 설계자가 스스로 선택하도록 하였다.

Purpose: This study was a descriptive methodological study to develop protocols for school health practice to manage health problems of primary school students effectively. Methods: The protocols were verified by 12 experts and 10 health teachers, respectively, to secure a two-step content validity. Results: The main 8 health problems of primary school students were headache, abdominal pain, musculo-skeletal, respiratory, circulatory, ophthalmic, and oral-dental problems, and fever. The developed protocols consist of 8 algorithms, which are to help decision making in the course of assessing health problems and to identify and link related factors and associated symptoms, 8 school nursing records based on the Omaha classification system, and the list of 441 links between nursing assessment and nursing intervention. Conclusion: The use of the protocols is expected to make it easier for health teachers to apply the nursing process in solving the health problems of primary school students and supporting the rational decision making process, eventually improving the quality of primary school health. Repeated studies for protocol standardization as well as studies dealing with various health problems not included in the protocols should be performed for the development of school health practice protocols.
