Characterizations of probability distributions by different regression conditions on generalized order statistics has attracted the attention of many researchers. We present here, characterization of Pareto and Weibull distributions based on the conditional expectation of generalized order statistics extending the characterization results reported by Jin and Lee (2014). We also present a characterization of the power function distribution based on the conditional expectation of lower generalized order statistics.

A family of continuous probability distribution has been characterized through the difference of two conditional expectations, conditioned on a non-adjacent record statistic. Also, a result based on the unconditional expectation and a conditional expectation is used to characterize a family of distributions. Further, some of its deductions are also discussed.

In this paper we study the existence of conditional expectation for closed and convex valued Pettis-integrable random sets without assuming the Radon Nikodym property of the Banach space. New version of multivalued dominated convergence theorem of conditional expectation and multivalued $L{\acute{e}}vy^{\prime}s$ martingale convergence theorem for integrable and Pettis integrable random sets are proved.

Purpose: The aim of this study was to analyze the gap between the nurse's expectation and perception of internal marketing activities. Methods: The participants of this study were 521 nurses working in four general hospitals. The data were collected by self-reporting questionnaires. They were analyzed using descriptive statistics and paired-t test. Results: First, the mean of the nurse's expectation of internal marketing activities was 3.83, and perception was 2.54, showing a significant difference. Second, in all of the five subcategories of internal marketing activities, there were also statistically significant differences. Regarding the vacation system, the expectation score was highest, and support of academic education programs in education and training, payed-leaves during vacation, discounting of medical fees in employee welfare, distress management and two-way intercommunication, and allowances in reward were followed. Conclusion: These results will be used to develop focused internal marketing strategies to enhance the nurses' motivation.

This study explored the effects of expectatioin, performance, and disconfirmatoni on satisfaction of theme park users. Everland was chosen as the study area, and 260 users were selected by the nonprobability sampling. In expectation disconfirmation paradigm, expectation should be measured before purchase, and performance, disconfirmation and satisfaction should be measured after purchase. An entrance survey was done to measure expectation, and an exit survey to measure performance, disconfirmation, and satisfaction. Maximum likelihood method was used to estimate structural equation model by the LISREL 7.2. Performance had the most significant effect on satisfaction among three variables. The satisfaction of theme park users depends largely on it, therefore, the consideration of visitors' performance should e essential for managers.

Theoretically and practically, it is very important to understand the way which tourist satisfaction is operated. The purpose of this study is to identify interaction among the determinants of tourist satisfacton process. A model of tourist satisfactioin process is developed based based on the confirmation / disconfirmation which is originated from consumer behavior literature. Three elements of the model include 'expectation','performance', and 'discrepancy between expectation and performance'. 340 questionnaires were delivered to find Everland visitors' perceptions of the determinants of tourist satisfaction. LISREL 8.14 was used to analyze the interaction among the determinants. The results are as follows : 1) 'expectation' has indirect effect on tourist satisfaction while 'performance' and 'discrepancy' has direct effect on the tourist satisfaction, 2) two precedent variables such as 'expectation' and 'performance' have indirect effect on the satisfaction through 'discrepancy',3) among the three determinants it is found that 'performance' is the most effective determinant of tourist satifaction, and 4) the model which was composed from the aspect of 'travel cost' was more effective to describing tourist satisfacton rather that from the aspect of 'service quality'.

This article examines customer repurchase intention change. Specially we focus whether pre-purchase expectation and post-purchase satisfactions to retailers contribute to repurchase intention change. The previous works of customer satisfaction and repurchase intention were empirically tested the product based on the disconfirmation theory. But this study present the relations between the satisfaction and repurchase intention to stores. First, this study deliberately classified the types of stores. And I set the repurchase intention process apart into three part for empirical wok. In one part, the effect of trust has on expectation was tested. At the second procedure I test the expectation impact to satisfaction. Part three was about the relations between satisfaction and repurchase. In empirical test, convenience 200 sample was used. For these sample I use questionnaires that include the intensity of repurchase intention to postpurchase dissonance. Statistically regression uses as a solid tool to prove the relations between consumer satisfaction and repurchase. MANOVA results support the level of effect that different each store. They were supported through regression analysis. Also, by MANOVA the difference of them was turned out to be significant.

Purpose: The purpose of this study is to find factors affecting the acceptance intention of autonomous mobility service by applying the unified technology acceptance theory(UTAUT). Methods: The measurement items for each component of this study were modified to meet the purpose of the study by referring to previous studies related to mobility based on UTAUT, which has secured validity and reliability in many studies. The collected data through the online survey were analyzed using hierarchical regression analysis. Results: It was found that performance expectation, effort expectation, social influence, and facilitation conditions for autonomous mobility service had a positive effect on acceptance intention. Also, in this relationship, it was confirmed that driving experience moderated the relationship between performance expectation and acceptance intention, and between effort expectation and acceptance intention. Conclusion: Understanding the public's acceptance of autonomous mobility services, and suggesting strategic implications for the direction of service development to companies that are pushing to enter the autonomous mobility service market.

This study measured college students' levels of satisfaction with their cyber learning through an online survey of students who had taken one or more cyber learning before. 500 returned and usable questionnaires were analyzed and SPSS WIN 12.0 was used for the descriptive statistics, t-test, factor analysis and analysis of covariance structures. The results are as follows; First, college students were very interested in their cyber learning. Their decision to take the cyber learning was initiated more by emotional motives (m=3.13) than by rational motives (m=3.35). Second, the consumers' expectations for the cyber learning were divided into the 'Expectation for service quality' and the 'Expectation for economy,' and their 'Expectation for economy'(m=4.02) was higher than their 'Expectations for service quality'(m=3.60). Third, the consumers' expectations for the cyber learning and the results of the cyber learning were analyzed, and a discrepancy between these two were also analyzed. The analysis of discrepancy between the two showed that the average of the results was lower than that of the expectations, which means that the cyber learning did not meet the consumers' expectations in every aspect, However, the average satisfaction level was 3.20, which means consumers were satisfied with the cyber learning overall. Fourth, causes of dissatisfaction with the cyber learning were divided into internal factors due to personal matters and external factors due to classes and other factors. It was found that dissatisfaction due to internal factors was greater than that due to external factors. Lastly, the factors affecting satisfaction/dissatisfaction with the cyber learning and willingness to use it again were analyzed. The results showed that the motive for its use affected the formation of expectation but it did not affect the results. Satisfaction with the cyber learning affected the willingness to use it again positively. However, the effect of dissatisfaction on the willingness to use it again was not statistically significant.
