Method: The study was carried out during the period from June 16 to July 12, 2003. The subjects in the study were 397 elementary students attending four elementary schools in Chungcheongbuk-do and Kyunggi-do. Self-rating questionnaire included general characteristics, internet addiction scale, internet expectancy scale, and self-efficacy scale. Data was analyzed using SPSS/WIN10.0 by unpaired t-test and Pearson corelation coefficient. Result: In this study, the mean score of internet addiction was 20.7. Internet dangerous group was 12.6% and internet addicticted group was 0.3%. The score of internet addiction was significantly different according to parents' concern, aversion to school life and extracurricular lecture. The mean score of internet expectancy was 27.1. The score of Internet expectancy was significantly different according to popularity among friends and easiness of making friends. The mean score of self-efficacy was 55.8. The score of self-efficacy was significantly different according to conversation with parents, enforcement of parents on learning, aversion to school life, aversion to extracurricular lecture, existence of intimate friend, popularity among friends(p=.000), and easiness of making friends. Conclusion: This study showed that prevalence of internet addiction was much lower than expected, but the score of internet addiction and internet expectancy can be different according to parents' concern and relationship with friends. Therefore parents must be concerned about their children and their school lives to prevent internet addiction.

This study examined the difference in the usage of internet banking users between Korea and China. This model tests various theoretical research hypotheses relating to internet banking, The Unified Theory of Acceptance and Use of Technology(UTAUT). The factors influencing on the use intention of Internet banking have been classified as performance expectancy, effort expectancy, social influence and facilitating conditions. The proposed model was empirically tested using data collected from a survey of internet banking users in Korea and China. The model is used by SPSS 15.0 and AMOS 7.0 for analysis on the sample collected from 272 respondents. The result of hypothesis testing are as follows. First, performance expectancy and social influence positively influence use intention of internet banking user both Korea and China. Second, facilitating conditions only positively influence on the usage of internet banking users in Korea. On the other side, effort expectancy do not influence the use intention of internet banking users in both two countries.

This study investigated the psychosocial characteristics of children and adolescents who were addicted to internet. 1107 children and adolescents were administered several self-report inventories assessing internet addiction, internet expectancy, self-control, parent-adolescent communication, parent control of internet, peer relation, and loneliness. Results indicated that internet addicted adolescents had more expectancy for internet, less self-control, more dysfunctional communication with parents, and more withdrawn from peers than non-addicted. To determine relative contributions of these variables, multiple regression was conducted. It was demonstrated that internet expectancy, self-control, dysfunctional parentadolescent communication, and parent control of internet explained adolescent internet addiction.

This study aims to confirm which factors related to technology acceptance affect generation MZ's use of luxury fashion platforms. For this purpose, Internet self-efficacy and technology readiness were added as new exogenous and moderating variables using extended UTAUT. Then, performance expectancy, effort expectancy, social influence, and facilitating condition as a factor of UTAUT were set as mediating factors. Response data were collected through questionnaires for generation MZ with experience in using luxury fashion platforms, and a factor analysis, reliability analysis, correlation analysis, and path analysis were conducted using the SPSS and AMOS statistical programs. According to the results, the Internet self-efficacy of generation MZ significantly affected on performance expectancy, effort expectancy, social influence, and facilitating conditions on the luxury fashion platform. Moreover, performance expectancy and social influence had a significant effect on the use intention of luxury fashion platforms, but effort expectancy and facilitating condition did not have a significant effect on use intention and use behavior. Additionally, as the moderating effect of technology readiness affects only the relationship between social influence and behavioral intention, it was confirmed that social influence is an important variable with the characteristics of MZ consumers. Therefore, it is deemed necessary to recognize the importance of social influence when trying to use new technologies targeting generation MZ in the fashion industry.

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 : Internet addiction is a newly appeared addictive phenomenon that is defined as 'difficulty in real life due to internet over-use', 'excessive time spent on the internet or replacement of genuine real relationships with superficial virtual ones' or 'weakness in self-control about internet use and if discontinued, fallen in psychological confusion and anergic state'. This study was aimed to compare the internet addiction rate, demographic factors, computer using patterns, anxiety, depression, and internet self-efficacy and outcome expectancy between Korean middle and high school students in three areas - Seoul, Cheonan, and Rural areas - that were different in economic, cultural, and geographic state. Methods : Subjects are consisted of middle and high school students in Seoul, Chunan, and Rural areas(N=1718). Self-rating questionnaire included demographic data, Korean Spielberger State-Trait Anxiety Inventory, Korean Self-Rating Depression Scale(SDS), questions for internet-using pattern, Korean version of Internet Addiction Scale invented by K. S. Young, Internet Self-efficacy and Out-come Expectancy Scale. Results: In this study, prevalence of internet addiction was 2.9%. There was no significant difference found in prevalence of internet addiction among three areas. In all subjects, there were significant differences in anxiety, depression, internet self-efficacy and outcome expectancy, leisure style, places of internet use, internet connecting method, and insight on internee addiction. But, in addicted group, there was no significant difference among three areas. Conclusion: This study suggested that the difference in economic, cultural, and geographic state was not related to prevalence of internet addiction. Although there were significant differences in anxiety, depression, self-efficacy associated with internee use, leisure style, places of internet use, internet connecting method, insight on internet addiction among three areas, there were no significant difference in addicted group among three areas. So, we concluded that the difference in economic, cultural, and geographic state did not influence the prevalence of internet addiction, and despite the difference in economic, cultural, and geographic state, people in three areas were equally influenced by internet addiction.
