Purpose: This research aims to provide empirical evidence on the impact of digital literacy on behavioural intention regarding using technology for distribution of higher education. Design, Methodology, and Approach: Quantitative analysis was carried out using Covariance-Based Structural Equation Model with data collected from 901 students who fully experienced 2-year study online at different universities in Vietnam. The structural model was built with digital literacy as the primary indicator and other variables were included based on modified version of Unified Theory of Acceptance and Use of Technology (UTAUT2) by adopting performance expectancy, effort expectancy, social influence, habit, and hedonic motivation variables specifically for education sector. Self-efficacy was added to eliminate possible bias in technology acceptance. Results: From the results of model estimation, digital literacy presented positive impact on the online distribution of higher education in Vietnam. The mediating effects of various indicators such as performance expectancy, effort expectancy, social influence, habit, hedonic motivation, and self-efficacy are significantly determined by research model. Conclusion: The higher level of digital literacy of the students, the more likely that they will use technology in higher education study, especially online learning. Additionally, the mediating effects of indicators from the UTAUT2 theoretical model were also evident to be 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.

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.

Objectives: Subjective life expectancy (SLE) has been found to show a significant association with mortality. In this study, we aimed to investigate the major factors affecting SLE. We also examined whether any differences existed between SLE and actuarial life expectancy (LE) in Korea. Methods: A cross-sectional survey of 1000 individuals in Korea aged 20-59 was conducted. Participants were asked about SLE via a self-reported questionnaire. LE from the National Health Insurance database in Korea was used to evaluate differences between SLE and actuarial LE. Age-adjusted least-squares means, correlations, and regression analyses were used to test the relationship of SLE with four categories of predictors: demographic factors, socioeconomic factors, health behaviors, and psychosocial factors. Results: Among the 1000 participants, women (mean SLE, 83.43 years; 95% confidence interval, 82.41 to 84.46 years; 48% of the total sample) had an expected LE 1.59 years longer than that of men. The socioeconomic factors of household income and housing arrangements were related to SLE. Among the health behaviors, smoking status, alcohol status, and physical activity were associated with SLE. Among the psychosocial factors, stress, self-rated health, and social connectedness were related to SLE. SLE had a positive correlation with actuarial estimates (r=0.61, p<0.001). Gender, household income, history of smoking, and distress were related to the presence of a gap between SLE and actuarial LE. Conclusions: Demographic factors, socioeconomic factors, health behaviors, and psychosocial factors showed significant associations with SLE, in the expected directions. Further studies are needed to determine the reasons for these results.

Purpose - There are many antecedences and consequences of the positive emotions of customers. The purpose of this research is to examine how Chinese service companies improve not only the positive emotions of customers but also the quality of life through effective verbal and nonverbal communication. Furthermore, we tried to analyze the moderating role of negative expectancy disconfirmation perceived by customers in those causal relationships among the variables. Research design, data, and methodology - The eight hypotheses were proposed and we tested them empirically in this research. Four hypotheses were about the relationship among communication, positive emotion, trust and quality of life. The other four hypotheses were about the moderating effect of negative expectancy disconfirmation in the causal relationships among four variables such as communication, positive emotion, trust and quality of life. A total of 356 samples who had visited the service companies in China were surveyed and 8 hypotheses were tested by empirical analysis using SPSS and AMOS. Results - The results of this research are as follows. First, positive verbal communication and nonverbal communication of employees in the service company have a positive effects on the positive emotions of customers. Second, positive emotion has a positive effect on the overall quality of life on the customer side as well as the trust on the corporate side. Third, negative expectancy disconfirmation perceived by customers has negative moderating effect in the causal relationship between employees' positive verbal communication and customers' positive emotion, and it also has a negative moderating role in the causal relationship between customers' positive emotion and overall quality of life. Conclusions - Based on these results, there can be such implications as follows. First, managers and employees of service companies can induce positive emotion of customers through effective communication. Second, service companies should try to improve not only the corporate-side performance like trust but also the customer-side performance like quality of life. Third, it will be significant for them to lower the level of negative expectancy disconfirmation for the purpose of improving not only the positive emotions of customers but also the quality of customers' life.

In recent years the life expectancy of the Korean people has been increasing appreciably because of the improvement in living conditions and public health facilities as well. However, there exist considerable constraints in the measurement of Korea's mortality rate. In elaboration, there are quite a few persons who do not submit birth and death reports, thereby lowering the reliability of statistical data. The 1978-1979 life table of the Korean people is still considered the latest one. Nevertheless, a decade has passed since its publication, and the need for a better life table reflecting realities is inc-reasingly growing. Capitalizing on the annual report of demographic statistics and demographic sample survey data m 1988, I have worked out the 1986 tentative life table of the Korean people and found out the following : 1. The male life expectancy in the 1978-1979 life table of the Korean people is 62.7 years old, and that of the female sex is 69.1 years old whereas the average life expectancy of the male sex in the 1986 life table stands at 66.3 years old, and that of the female sex is 74.5 years old. The average life expectancy is up by 3.5 years old for the male sex and also, up 5.4 years old for the female sex, res-pe ctively. 2. A gap between the male and female life expectancies in the 1978-1979 life table was 6.4 years old, while that of the 1986 life table was 8.2 years old. It means the female life expectancy has increased substantially. 3. The infant mortality rate has decreased, compared with the 1978-1979 level, yet it is still above those of Japan and Taiwan. 4. The mortality rate of the middle - aged men in the forties remains high, as was the case in the 1978-1979 period.

In this paper, the relation model for three important entrepreneurial entities are studied based on the expectation theory for entrepreneurs. The three entrepreneurial entities include entrepreneurial expectancy, entrepreneurial outcome and expect growth intentions. In this study, the entrepreneurial expectancy is defined as the expectation about establishment, while entrepreneurial outcome and expect growth are related to entrepreneur's dominant idea for enterprises' operation and management. Based on the investigation data via questionnaire for 489 subjects, the relation model hypothesis for the three entrepreneurial entities is tested using structural equation model analysis. According to the analysis result, arguments can be made that entrepreneurial expectancy can have a significant positive effect on realization of successful entrepreneurial activities, and entrepreneurial outcome may have a significant positive effect on realization of expect growth intentions. Therefore, a kind of mutual promotion model can be observed among the three entrepreneurial entities. In addition, the proposed relation model is applied to both Korean and Chinese entrepreneur, and their differences are compared and discussed.
