This study paid attention to the notable increase of the use of diet/exercise apps on smartphones. Based on channel expansion theory and technology acceptance model (TAM), this study investigated how three predictors-Internet information use efficacy, Internet information credibility, smartphone use efficacy-affected one's attitude toward and intention to use diet/exercise apps. Results from a path analysis indicated that Internet information use efficacy and smartphone use efficacy positively predict the perceived ease of use of diet/exercise apps. Internet information credibility positively predicts the perceived usefulness of such apps. Moreover, there were gender differences in the effects of both Internet information use efficacy and Internet information credibility on the perceived usefulness of diet/exercise apps.

The purpose of this study is to investigate the effects of home informatization on the family resource management. For this purpose we analyze the level of home informatization focused on the Internet use and it's effects on the family resource management through time management and financial management. Data were collected from 582 housewives who use the Internet at home. The results show that home informatization through the Internet use has changed family resource management totally. It contributes to improve planning and efficiency of resource management, but simultaneously it causes the imbalance of resource management. And the Internet use of housewives also affects time allocation and household expenditure. These changes depend on socio-demographics variables, home informatization related variables, and personal resource variables. The results show that the ability to manage time and finance have much more importance to improve the level of planning and efficiency and to decrease the level of imbalance in managerial subsystem. The results of this research suggest several implications for public policy.

In this study, we investigate the individual-, parents-, and family-related variables affecting the internet overuse of adolescents by the gender, school grades and school systems, which is based on surveys of 480 students in the middle and high school, employing multiple regression analysis. Major findings are as follows. 1. In the case of male students, internet use was higher when the students are playing online games more often, when the students are under stress, or when they have lower self control. In the case of female students, internet use was higher when the students are playing online games more often or when the students are visiting pornographic sites more often. 2. In the case of middle school students, internet use was higher when the students play online games more often, when they use file downloads more often, when they have lower self control, or when they have parents who are setting lesser rules on the students' internet use. In the case of high school students, internet use was higher when they play online games more often, when they engage in internet club activities more actively, when they have lower self control, when they use e-mails less frequently, when they have fathers with better internet ability, or when they are under parents' strict control. 3. In the case of academic high school students, internet use was higher when they play online games more often, when they engage in internet club activities more actively, when they visit pornographic sites more often, when they have lower self control, when they have mothers with poor internet ability, when they use e-mails less frequently, or when they have fewer number of close friends.

Objectives: The overuse of the Internet among adolescents has increased dramatically in recent years, leading to pathological or problematic Internet use. Cognitive behavioral therapy (CBT) is known to be effective for the treatment of problematic Internet use, particularly for adolescents. The aim of the present study was to evaluate the therapeutic efficacy of group CBT for problematic Internet use in adolescents. Methods: A total of 17 patients aged 12-17 years who met Young's diagnostic questionnaire criteria of problematic Internet use participated in a school-based eight-session group CBT program. The level of problematic Internet use among participating students was measured using Young's Internet Addiction Scale (IAS). Depression and anxiety levels were evaluated using the Children's Depression Inventory (CDI) and the State-Trait Anxiety Inventory (STAI), respectively. Each construct was assessed at baseline, immediately after the intervention, and at a one-month follow-up visit. Statistical significance was based on a p-value of <0.05. Results: Immediately after the program, the IAS, CDI, and State Anxiety Inventory (SAI) scores were significantly lower than before the program. At the one-month follow-up assessment, the IAS scores remained low, and the CDI and SAI scores were even lower than immediately after the program. Conclusion: Group CBT was effective for adolescents with problematic Internet use, and was also demonstrated to improve depression and anxiety.

This study investigates internet shopping behavior of consumers. The rapid growth of the internet shopping markets is solely dependent on the voluntary adoption of internet shopping medium by the personal users. But the studies on this topic are very limited. Based on these facts, this study, recognizing the internet shopping medium as an innovation, studies how consumers understand and use innovative internet shopping medium by applying and extending the technology acceptance model proposed by Davis et. al.(1989). The results of the survey on 947 consumer panel reveal that compatibility, system quality have positive impact on the formation of perceived ease of use. And it is also shown that the perceived ease of use, system quality, and compatibility have positive influence on perceived usefulness, but computer-efficacy has no effect on perceived usefulness. Meanwhile, it is confirmed that perceived usefulness and compatibility have positive effect on attitude toward internet shopping behavior, but perceived ease of use has no effect. In addition, perceived security and social norm, as opposed to the hypotheses, are shown to have no effect on internet shopping behavior. Lastly, applications and related limitations are discussed.

Theoretically, both of fund transfer and balance inquiry which are typical Internet banking services are influenced by the beliefs on the use of Internet banking such as perceived risk and convenience, which have been shown as in the other studies. However, the use of fund transfer can be more sensitive than that of balance inquiry by the beliefs on Internet banking use since the former is not only more risk involved but also more complicated in using than the latter. The objective of this study is to analyze the relationship between the use of two Internet banking services-fund transfer and balance inquiry-and the beliefs on Internet banking use-security risk, convenience and social Influence. For this purpose, we provide the research model for explaining the difference between balance inquiry and fund transfer in the degree of influencing by security risk, convenience and social influence and test it empirically by collecting data from surveying for 206 internet banking users. In result, we show validity of the suggested model by Partial Least Square(PLS) approach.
