본 연구는 기존의 양분선택형(dichotomous choice : DC) 질문에서 고려하지 못했던 응답자 개개인 선호의 불확실성을 CV(contingent valuation) 모형에 명시적으로 포함하여, 보다 개선된 가치추정결과를 이끌어내고자 한다. 이를 위해, 설문의 전체 표본을 2개의 표본으로 분할하였다. 첫 번째 표본은 다중선택(polychotomous choice : PC) 질문법을 사용하였고, 두 번째 표본은 사후적 확신도 질문이 첨가된 DC 질문법을 사용하여 설계하였다. 선호의 불확실성을 고려한 다섯 가지 모형과 기존의 DC 모형을 적용하였으며, 각 모형들의 추정결과를 효율성 측면과 모형적합도 측면에서 비교해 보았다. 실증분석 결과, 첫째, WTP(willingness to pay) 추정치의 효율성 측면에서는 전반적으로 DC 모형이 더 우월했고, 모형적합도 측면에서는 PC 모형이 좀더 우월함을 관찰할 수 있었다. 둘째, 기존 DC 모형과 가장 유사한 PC 모형을 비교해 볼 때, 두 모형의 WTP 추정치는 통계적으로 다르지 않으나, DC 모형이 효율성과 의형적합도 측면에서 좀더 개선된 추정치를 가져다주었다. 셋째, DC 모형에서 선호의 불확실성을 고려한 경우의 WTP 추정치는 불확실성을 고려하지 않은 기존 DC 모형의 추정결과와 비교해 볼 때, 효율성과 모형적합도 측면에서 별다른 손실 없이, 최대 84% 정도 더 크게 추정되었다. 이러한 결과들은 WTP 추정에 있어서 PC 모형보다는 DC 모형을 적용하는 것이 더욱 적합하며, 일반적인 DC 추정모형에서 선호의 불확실성을 고려하지 않았을 경우 응답자의 보수적인 응답경향으로 인해 WTP 추정치가 실제 WTP보다 과소 추정될 수 있으므로 선호의 불확실성을 고려해야 할 필요가 있음을 시사한다.

The purposes of this study was to demonstrate the influence of fashion life-style, self-image and situational factors on consumer's apparel store choice for satisfaction of varied needs and high efficiency of marketing activity. A questionnaire was developed to measure research subjects based on theoretical study empirically. The questionnaire was administered to 270 women aged between 20 and 30 in Seoul. The results analyzed by factor analysis, cluster analysis, x2-test and oneway-anova. The results of empirical studies were summarized as follows: 1. Segmented groups of fashion life-style were classified practical/planning group, fashion- leader group, and shopping-oriented group. And store types which were prefered by those groups were department store/shopping center. 2. Segmented groups of self-image were classified actual-seeking group, modernity group and confidence group. And store types which were prefered by those groups were department store/shopping center. The Forecast of store choice on the base of self.image was showed that customers choose the store incongruous with self-image. But when it was analyzed each actual store choice. The Choice of high frequancy was congruous with self-image except for a specialty store/brand named outlet. 3. The significant differences could be found in choice of the store under particular purchase situations and especially at department stores and specialty store, their preference tended to be stronger as the degree of the store's involvement was hightened, but in the case of the generalization stores and the permanent discount stores, even though the degree of that involvement was low, their preference showed the same tendency.

Purpose: Understanding which product types of overseas travel (free independent travel vs. package travel) consumers will choose is one of the key issues of marketing and consumer behavior in travel agency management. Prior studies on overseas travel type preferences mainly focused on comparing regional differences (e.g., Asian vs. Westerner, or Korean vs. Australian, or Korean vs. Japanese, or American, French, Italian vs. Japanese) influencing the choice of overseas travel type. Another researchers focused on comparing cultural differences (e.g., individualism vs. collectivism, or individualistic culture vs. collectivistic culture), subcultural difference (e.g., acculturation; Koreans living in Republic of Korea vs. Koreans living in Australia), travel lifestyle, and socio-demographics (e.g., age, gender, income level, education level, marital status, occupation etc.). However, there are few studies that identify individual psychological differences (i.e., individual psychological differences within the same culture) influencing the choice of overseas travel type. Self-construal is a psychological factors that greatly influences choice behavior. The purpose of this study was to examine the role of self-construal as an antecedent variable influencing choice of overseas travel product type. Research design, data and methodology: To achieve the purpose of this study, the questionnaire survey method was used. Self-construal items composed of independent self-construal items and interdependent self-construal items. Product types of overseas travel were free independent travel (FIT) type versus package travel type. In this study, the correlation coefficient between independent self-construal and interdependent self-construal was nonsignificant. It meant that the relationship between independent self-construal and interdependent self-construal was orthogonal. Therefore it was analyzed that independent self-construal and interdependent self-construal separately. Reliability analysis, factor analysis, and logistic regression analysis (controlling gender and age) was used as the data analysis method. Results: According to the results of this study, the stronger independent self-construal, the more preference for the free independent travel type rather than package travel, and the stronger interdependent self-construal, the more preference for the package travel type rather than free independent travel. Conclusions: Self-construal is an antecedent variable influencing the choice of travel type. Travel agencies must consider the consumer's self-construal (independent self-construal vs. interdependent self-construal) before planning and designing overseas travel products.

Tourism marketing begins with understanding tourists' needs. However, understanding tourists' needs should be expressed by specific utility values rather than simple preference order for the purpose of developing tourism marketing strategies. This study aims at identifying tourist's stated preference of vacation destination attributes by using the conjoint analysis. In addition, this study is purposed to define relationship between attitude and preference, and to suggest implications to tourism marketing strategies. It was found that stated preference to such attributes as 'quality of accommondation', 'recreation activities' and 'accessibility' among the attitude segments was significantly different but stated preferences to diverse profiles made of these three attributes showed significant differences only in such attributes as 'quality of accommodation' and 'recreation activities'. This results make it possible to identify the function of preference to destination attributes in the vacation destination choice decision. It also embodies the relationship between tourist's attitude and vacation destination attributes.

The purpose of this research is that to study of musical performer's purchasing behavior, satisfaction and design preference, and to give the information for better performance costume market based on that result. The target for the survey is limited only for above 4th grade female students and have experienced more than three times of performances. Total 364 questionnaires are used for this research. The SPSS was used for the analysis. The results were, first, in the survey of place of purchasing, specialty shop for musical performance shop was the most. The most group for the budget that they spent was under 100,000 Won. Rational price for costume would be 150,000-300,000 Won. Most people purchase costume before 2 weeks and compare 3-4 stores mostly. There were not many complaints about being comfort for costume itself. The preference for costume was different depends on not only scale of performance but also whether solo, duet or trio or more. Also harmony with other person costume was most consideration factor when they perform duet or more. For the choice of shop factor following were considered the most important; various selections, kindness of sales persons and possibility for trying various costumes. However, locations of shop or delivery service were not important relatively. For the choice of costume factor, design color, comfort and functionality were considered the most important but price, quality and decoration were not. For 'the satisfaction after purchase costume' factor, people's opinions, best appearance on the stage and meeting image with themselves were considered the most important. Second, on the subject for 'design preference of costume based on type of performance', people chose different color of dress depends on what types of performance. In case of solo, they prefer vivid primary color; in case of trio or more, they prefer black; in case of duet, they prefer pastel tone. As for preference of sleeve design, all of them prefer non-sleeve type.

Purpose: The purpose of the study was to examine the career obstacle factors and career identity according to career choice type among paramedic students. Methods: A self-reported questionnaire was completed by 234 paramedic students in C area from August 25 to September 3, 2015. The questionnaire consisted of general characteristics of the subjects, career obstacle factors, career identity, and types of career choice. The data were analyzed by t test, ANOVA, post hoc $Scheff{\acute{e}}$ test, Pearson's correlation analysis, and multiple regression analysis using SPSS v. 20.0. Results: Career obstacle factors and career identity of paramedic students had significant differences on motivation of university choice, major satisfaction, and job preference. A stable type of career choice showed a significantly lower score for career obstacle factors and a higher score for career identity. Career identity had a strongly positive relationship with major satisfaction and had a negative relationship with career obstacle factors. Logistic regression analysis revealed that the main variables affecting career identity were types of career choice, motivation of university choice, major satisfaction, and career obstacle factors. The explanatory power was 58.0%. Conclusion: The development of a career integrity enhancement program can solve the career obstacle factors for paramedic students.

Our city structure is being complicated from the development of industry and the increase in population. It makes the ground space overcrowded, so underground space is systematized for use. Because this underground space has very complicated configuration, people have difficulty in finding the route in the underground space. Therefore It is demanded to comprehend configuration of the various space structure, predict pattern of the moving and analyze induction factor of the moving. When people are in the conflagration or dangerous situation, they are in the habit of using the route which they are used to go to and from. It is needed to analyze moving pattern of the pedestrian who usually use the underground space for the sake of dealing with conflagration in the underground space. Finally, this study suggested that general characteristic, distribution, moving route of the pedestrian and factors influencing that they choose the route which the research finds out.

The experience of many countries strongly suggests that bad governments and institutions have been a serious, if not the most serious, obstacle to economic growth and industry-structural adjustments. All public sectors pursue a mix of both predatory and productive activities-bad governments emphasizing the former, while good governments finding a way of promoting the later. In fishery public policy studies, much confusion exists about the roles of policy illustration and prescription. In general fishery public sectors involve collective actions by numerous individuals under conditions of uncertainty, complexity, bounded rationality, and imperfect information structure. All collective fisheries action organizations consist of a center(e.g., government), which leads fishery group actions, and peripheral participants(e.g., fishermen), which are controlled by the government. A paradigm is developed that gives both theoretical and empirical meaning to the constitutional determination of fisheries political preference function or fishery public sector governance structures. Three relevant spaces are specified: policy instrument, results, and constitutional. The collective-choice rules of the constitutional space structure the tradeoff between public and special fishery interest groups. Fishery public sectors seeking sustainable reductions in wasteful rent-seeking fishing activities should select constitutional principles and institutional structures that tend to promote resource sustainability. In particular, the effects of internal and external events on fisheries may result in a greater or lesser concentration of interest group power. Thus, the structure of the fishereis political power must be assessed in any prescriptive evaluation of alternative fishery governance weights.

In route guidance systems fastest-path routing has typically been adopted because of its simplicity. However, empirical studies on route choice behavior have shown that drivers use numerous criteria in choosing a route. The objective of this study is to develop computationally efficient algorithms for identifying a manageable subset of the nondominated (i.e. Pareto optimal) paths for real-time vehicle routing which reflect the drivers' preferences and route choice behaviors. We propose two pruning algorithms that reduce the search area based on a context-dependent linear utility function and thus reduce the computation time. The basic notion of the proposed approach is that ⅰ) enumerating all nondominated paths is computationally too expensive, ⅱ) obtaining a stable mathematical representation of the drivers' utility function is theoretically difficult and impractical, and ⅲ) obtaining optimal path given a nonlinear utility function is a NP-hard problem. Consequently, a heuristic two-stage strategy which identifies multiple routes and then select the near-optimal path may be effective and practical. As the first stage, we utilize the relaxation based pruning technique based on an entropy model to recognize and discard most of the nondominated paths that do not reflect the drivers' preference and/or the context-dependency of the preference. In addition, to make sure that paths identified are dissimilar in terms of links used, the number of shared links between routes is limited. We test the proposed algorithms in a large real-life traffic network and show that the algorithms reduce CPU time significantly compared with conventional multi-criteria shortest path algorithms while the attributes of the routes identified reflect drivers' preferences and generic route choice behaviors well.
