The present study examined the consumer's evaluations of apparel quality and price, and the brand recognition according to the consumer's decision making styles(quality-conscious, brand-conscious, and price-conscious consumers). The two hundred and three subjects were asked to evaluate the quality and price of the two almost identical experimental blouses except for brand labels. One was the national brand, Keith and the other was the private brand, Ivy house. Also, the subjects were asked to answer if they recognize these two brands. The data were collected by self-administered questionnaire and were analyzed by frequency, percentage, one-way ANOVA, two-way ANOVA, and factor analysis. The results of the study were as floows: (1) Examining the perceptions of product qualities, generally speaking, all three types of the consumers evaluated the national brand's qualities more highly than those of the private brand. However, in-part, the price-conscious consumers evaluated some product charac-teristics more highly than those of national brand: touch of fabric, sewing, and the hemline finishing. (2) Investigating the perceptions of product prices, All three types of the consumers evaluated the price of the national brand more highly than that of the private brand. Among those, the price-conscious consumers recognized the price of the national brands most expensively. (3) Identifying the brand recognition of the two brands, the brand-conscious consumers showed the highest brand recognition and the price-conscious consumers showed the lowest brand recognition in both national and private brands, 51.9% of the total respondents identified the private brand showing comparatively high brand recognition. (4) Examining the relationship between the demographic factors and the consumer decision making styles, the monthly household income was statistically significant. Namely, 71.4% of the brand-conscious consumers have the monthly household income of 3,000,000 Won or higher which means that the higher monthly household income, the higher tendency to be brand-conscious consumers.

원자력발전소 주요기기의 교체에 대한 경제성평가는 대부분 결정론적 방법으로 수행하고 있으나 불확실성을 가진 입력변수에 따라 결과 값이 매우 가변적일 수 있다. 현실세계의 불확실성을 보다 면밀히 고려하기 위해 확률론적 방법을 활용하고 있다. 본 논문에서는 decision analysis를 이용하여 원자력발전소 기기 교체에 대한 경제성평가를 확률론적 방법으로 수행하였다. Decision analysis는 불확실성과 위험에 직면한 선택을 이끄는 기회를 이성적으로 개선하기 위한 방법론이며, 확률론과 통계이론이 복합되어 있다. Decision analysis의 주요요소는 여러 가지 방안 중 선택한 대안, 선택으로부터 결정된 결과, 그리고 다른 대안과 비교해서 상대적인 우선순위이다. 또한, decision analysis는 값, 불확실성, 그리고 위험도를 구조적으로 통합하는 원리를 제공한다. Decision analysis의 중요한 이점은 이러한 불확실성과 위험도에 대한 처리에 있으며, 모델은 influence diagram과 decision tree를 이용하여 작성한다. 본 논문에서는 decision analysis를 이용하여 국내 A형 원자력발전소 증기발생기의 최적교체시기를 결정하여 보았다. 이러한 방법은 향후 원자력발전소 주요기기의 교체에 관한 경제성평가시 적용할 수 있을 것으로 기대된다.

We evaluate the technical and organizational aspects of the severe accident management guideline (SAMG), focusing on the decision-making process in the technical support center (TSC). From the technical aspects, we conclude that the present SAMG is a good tool that can assist the TSC in efficiently managing probable severe accidents. However, we suggest that the clear separation of the emergency operating procedure (EOP) and SAMG, which shifts plant control from the main control room (MCR) to the TSC, might not be an effective framework from an organizational perspective. Studies on organizational behavior demonstrate that a group decision made under a risky situation might be polarized in either a risky or cautious way. We recognize that we cannot be free from the polarization effect since the current SAMG recommends that the TSC evaluate the advantages and disadvantages of strategies to be implemented and choose the best one based on a group decision process. Illustrative examples of accident management under risky conditions are recapitulated from previous studies of the authors and we propose that the SAMG should be more proceduralized to remove this polarization from the decision-making process.

This study addresses the evaluation criteria of multimedia authoring tools(MATs), the way which decision-maker can exclude outlier matrix from group using the concept of the compatibility index, and how AHP can be applied to the selection of MATs in a group decision-making environment. The AHP technique allows an evaluator to quantify the relative importance of elements at each hierarchy and to calculate the composite relative weights for each product(i.e. MATs). This decision process allows setting to priority of the MATs based on the AHP. The results indicated that technical ability of MATs was the most significant factor in affecting their decision, trailed by managerial efficiency and vendor support. To the experts, multimedia data support was the less important than development interface. Also, the results indicated that product A(0.510) was their first choice, trailed by product C(0.286) and B(0.204). Assessing the composite relative weights revealed that expert group's members were consistent with the rankings of decision variables(evaluation criteria variables) statistically in selecting their MATs. Therefore, we believed that expert group's members have achieved sufficient agreement to permit the use of geometric mean to average the group's preference without obscuring the differences of individual opinions.

The purpose of this paper is to develop a knowledge-based real-time decision support system to support decision makers for efficient berth operation of Inchon Port. In these days, the efficient berth operation has been many studied. The berth operation rules differ from port to port and the problem is highly dependent on natural, geographical and operational environment of port. In Inchon Port, the ship's entrance into port and departure from port is extremely affected by the status of dock and berth because of capacity restriction. First, we analyzed the specific characteristics of Inchon Port such as dock based on the data of 1997. And then, we construct the database of experts knowledge for berth utilization. Finally, we build the real-time decision support system for the efficient berth operation of Inchon Port to make the better berth allocation in case of not only regular scheduling but also dynamic scheduling such as delay in berth operation and exchange of ship between berths. The DSS is developed with graphic user interface(GUI) concept to help the user determining user interactive updating of the port status. Then this DSS will be provide decision maker with an efficient and fast way to berth allocation, and reduce wastes of time, space, and manpower in Inchon Port operation.

While various efforts are being made to ensure aviation safety, air accident rate induced by pilot human factors is still high worldwide. In particular, among pilot human factors, it would be the most important issue for pilots to anticipate and recognize flight environmental factors beyond their control and to make a positive decision making(ADM). In the Republic of Korea Air Force(ROKAF), there were many dizzying experiences induced by bird strike incidents and developed into dangerous moments such as damage to the aircraft and pilots' increased mental stress. It is a matter of serious concern in terms of safety management and human factors to dismiss bird strike incidents as inevitable misfortune due to environmental factors. In 2018, the ROKAF Aviation Safety Agency(ASA) conducted an experimental study to enhance pilots' ADM competence that can anticipate and avoid a bird strike. As the way of the study, 'Bird Strike Preventing Information' had been written and distributed every week by the ASA to flight units in the ROKAF during the period of the study. Through enhanced pilots' perceptual ADM competence, there was a noticeable number of reduction in bird strike incident compared to previous years of the experimental study.
