This study was conducted to investigate the relationship between contingencies of self-worth(superiority and others' approval), college adjustment and expectancy for future success and the mediating role of cognitive flexibility in these relationships. For this study, data from 460 college students were analyzed. The results were as follows. Contingencies of self-worth(superiority) were positively associated with college adjustment and expectancy for future success, while contingencies of self-worth(others' approval) were negatively associated with college adjustment and expectancy for future success. Second, the results of structural equation modeling indicated that cognitive flexibility fully mediated the relationship of contingencies of self-worth (superiority and others' approval) with college adjustment and expectancy for future success. Third, even the contingencies of self-worth(other's approval) were negatively associated with cognitive flexibility, and if the latter was high, it influenced college adjustment and expectancy for future success. Finally, the meanings and limitations of this research and implicationsfor counseling strategies and interventions were discussed in detail.

IT industry has rapidly changed with unlimited competition. In this situation, this article is searching for methods to enhance work engagement(WE) which increases workers' and organizations' performance. Servant leadership(SL) involves organizational change, thus one dimension of SL named commitment to the growth of people(CGP) which focuses on people' development would play a decisive role in IT industry, since member's capacity makes a success of this field. Since CGP would influence on perceived organizational support(POS), workers would have positive attitude to work. Furthermore, expectancy has a critical role for CGP which is related to the future. In future oriented viewpoint, if a leader supported members' growth and they had positive expectancy for the future, they would have higher POS, then WE also will be increased. The purpose of this study is to explain the importance of CGV, expectancy and POS, since they enhance WE which is the key factor for success of IT organizations and members in today.

In the rapidly developing 4th industrial revolution. RPA is increasing in use at home and abroad due to its advantages of simplifying workflow and providing flexibility and scalability at the same time. Thus, this paper conducted an empirical study on companies using RPA to determine which factors affect the intention to use the services provided by RPA systems. As system characteristics, exogenous variables were selected as information quality, system quality, and service quality of the information system success model. The endogenous variables were selected as the system acceptance factors for the performance and effort expectancy of the integrated technology acceptance model, and the perceived economic values and functional values were additionally selected. For the purpose of this study, a structured questionnaire was used for empirical analysis and the proposed hypothesis was verified through the path analysis of structural equations. As a result of the study, there was no significant relationship between service quality and effort expectancy, between service quality and economic value, and it was verified that the relationship between other factors was positively significant.

This study estimated a dual path model to predict consumers' intention to use a QR code virtual store by the effect of a mobile transaction system and a facilitating condition that also examined the role of experience and the use of an intention model in the context of a QR code virtual store. A longitudinal field study was conducted at selected QR code virtual stores. A questionnaire containing mobile transaction system, facilitating condition, performance expectancy, effort expectance, and intention to use was administered at two different points in time: Initial use (T1) and the second use after one month (T2). This study sampled 109 subjects who voluntarily participated in field studies twice at different time points (pooled sample=218). Participants were asked to visit at the QR code virtual store and undertake shopping tasks on their smartphones. The estimated dual path model showed that a mobile transaction system had a positive effect on performance expectancy, which influenced intention to use; however, facilitating condition had a positive effect on effort expectancy, but the effort expectance did not lead to intention to use. The effort expectance significantly also affected the performance expectance influencing intention to use QR code virtual stores. It was also found that use experience moderated the effect of mobile transaction systems on performance expectancy. The findings discussed a critical and success factor in consumer technology acceptance and use over time. A managerial implication was also discussed to capture potential users by emphasizing performance expectancy with the superiority of an innovative system or consumer facilitating condition as external resources in the introduction stage of new technology.

Historically, the en-users' acceptance of the expert systems(ES) have generally been used as a proxy for the ES' implementation success by both practitioners and academicians. However, with regard to bank loan decisions, most loan officers approach the acquisition of an ES with apprehension. In order to overcome this skepticism, more research should focus on the behavioral aspects relate to systems acquisition and usage. This research applied Vroom's(1964) expectancy theory in an effort to predict end-users' motivation to use an ES in a bank loan decision context. Because human behaviors and judgements are nonlinear rather than linear functions, accurately predicting human behavior is very difficult. To increase the prediction power for end-users' motivation to use an ES in a bank loan decision context, this research used an artificial neural network (ANN) model. In this research, an attempt was made to evaluate adequacy of the surrogates by analyzing differences between real bank loan officers and student surrogates in applying expectancy theory to estimate bank loan officers' motivation to use ES in a bank loan decision context.

This study was performed to investigate the mean life expectancy of dental prosthetic restorations. The author has examined 352 dental prosthesis clinically and radiologically, and decided the success(survival) and failure(mortality) of the dental prosthesis. The dental prosthesis which had been treated in the Seoul National University Dental Hospital, two private clinics in Seoul, one university dental hospital, and two private clinics in local province were included in this study. The survival analysis using product limit estimator was used and the mean life expectancy of each type of dental prosthesis was calculated. The results were as follows : 1. The life expectancies were 10.5 years in gold crown and bridge, 8.5 years in porcelain fused to metal crown and bridge, 8.3 years in nonprecious metal crown and bridge, 8.1 years in removal partial denture, and 7.7 years in full denture. 2. The causes of mortality were in the order of dental caries(24.6%), fracture of dental prosthesis(19.2%), periodontal problems(18.6%), chronic chewing difficulty and dysfunction due to dental prosthesis(15.0%), excessive exposure of abutments due to the marginal defect of dental prosthesis(14.4%), abnormal occlusion due to severe attrition of artificial teeth in dentures(3.0%), periapical problems(2.4%), perforation of dental prosthesis(1.8%), and loose contacts with neighboring tooth(1.2%). 3. Among survival cases, 66.5% showed normal chewing ability and 31.9% showed partial chewing ability. However, 1.6% of them complained loss of chewing ability. 4. Among failure cases, 6.6% showed normal chewing ability and 38.9% showed partial chewing ability. However, 54.5% of them complained loss of chewing ability.

In July, 2015, the Korean national assembly passed 'Act on Capital Markets and Financial Investments,' and therefore, it was expected that the crowd funding would be activated owing to a variety of fundraisings and investments. Hence, for the success of the crowd funding, this paper tried to identify the factors affecting the funding. In this study we analyzed the core variables of the Unified Theory of Acceptance and Use of Technology(UTAUT) and their perceived risks on the crowd funding participants' intentions as well as the mediating effects of the attitudes; the core variables of UTAUT were performance expectancy, perceived risk, facilitating conditions, social influence, and the like. As a result, it was found that such facilitating conditions as performance expectancy and social influence would affect crowd funding participants' intention positively, but that effort expectancy and perceived risk would not significantly affect their intention. On the other hand, as a result of testing the mediating effects of the attitudes, it was found that performance expectancy and social influence would have significant mediating effects on participants' intention.

The Korean Health Insurance (KHI) has been introduced since 1977 and it took only 12 years that KHI had accomplished the total coverage of Korean population. The remarkable success of KHI can be compared with other OECD countries which had taken some 30 years to over 100 years to establish the total coverage of the population. Life expectancy at birth and the infant mortality rate in Korea in 2005 both surpassed the average figures of the OECD countries, The main reason for the success of KHI can be delineated with the three characteristics in KHI development; low premiums, low benefits, and low fee-schedule charges. However, these three characteristics of KHI, which had been the key for the rapid development of the system, have become terrible disadvantages for the stable development of KHI. The dissatisfaction and discontent of health care providers are ever increasing. The population is reluctant to pay more premiums though it seems essential for the better care coverage. The health care system has been heavily distorted toward high technology-oriented expensive care. There should be several factors seriously tackled for the secure development of KHI in the future. This paper will review a brief history of KHI development, and I would like to make a suggestion of health insurance for children.
