This study focuses on customer perception of security control under Internet banking environment Internet banking customers' understanding of security control is insufficient. They are not fully aware of security technologies for Internet banking. Moreover, they cannot know which control is implemented and maintained on an Internet banking site when visiting the site. This study, therefore, attempts to find the impact of customer perception of security control on Internet banking acceptance. The research model is based on the TAM (Technology Acceptance Model), and introduces trust as an additional belief. Trust has been investigated in the marketing area, and begins to be focused in e-business area. A Web survey of Internet banking users collected 845 cases. Statistical analyses, using SEM (Structural Equation Modeling), partially supported the hypotheses that perceived strength of security control has an impact on three beliefs: trust, perceived usefulness, and perceived ease of use. We also verified the impact of these beliefs on attitude toward using, on behavioral intention to use, and on actual use. It is, therefore, verified that perceived strength of security control is a determinant of Internet banking acceptance.

The purpose of this study is to examine the effect of the Flow experience on purchase intention. The results of this study show that (1) the purchase intention through internet is increased in proportion to the degree of cognition of users' experience. (2) The "Flow" experiences during the time of navigating internet shopping-mall sites lead to different results due to the separate motive of searching internet shopping-mall sites. (3) It should analyze the market segmentation of internet users, using Flow experience in the future based on the relationship between Flow and on-line and off-line purchase intention. (4) Finally, it should study more profoundly on "experiential" Flow and "goal-directed Flow that it has to analyze the difference in Flow experiences between separate purposes of searching internet shopping-mall sites.

Internet shopping has continued to grow rapidly in the past decade. The main cause of this growth was the cheap price and convenience. However, internet shopping is uncertain compared to off-line shopping malls. Consumers don't have a chance to directly see and touch the products they will purchase. Many previous studies have suggested a trust to resolve this uncertainty. For purposes of the study, we examined how trust affects word-of-mouth effect and third-party assurance. Furthermore, using perceived risk and perceived price as moderating effects, we analyzed to see how each group-that is, those with high perceived risk and low perceived risk and those with high perceived price and low perceived price-shows differences in trust building. The results of empirical study found that both two variables of word-of-mouth effect and third-party assurance have significant impacts in trust building of internet shopping malls. It was proven that each group-those with high perceived risk and low perceived risk and those with high perceived price and low perceived price-showed differences in trust building. The results are expected to provide both the researchers of the trust study and hands-on worker with important implications.

Using data from the 2014 Survey on Internet Addiction performed by the National Information Society Agency, this study aimed to examine the influences of closeness with parents and awareness of Internet policies on Internet Addiction among adolescents in multicultural families in South Korea. Descriptive analyses showed that multicultural adolescents had on average 2.09 points on the whole scale of 15 items, but had on average 2.20 points on the sub-scale of withdrawal symptoms and on average 2.18 points on the sub-scale of tolerance symptoms. Multiple regression analyses revealed that multicultural adolescents' closeness with parents was significantly associated with lower levels of Internet addiction. Also, multicultural adolescents' awareness of Internet policies was also significantly associated with lower levels of Internet addiction. Based on the findings, this study suggested the necessity of providing parent education programs and enhancing awareness of Internet policies to reduce Internet addiction among adolescents in multicultural families.

The purpose of this study is empirically analyzing the effects of external factors(user knowledge, service characteristics, security), perceived risk, trust, ease of use, and usefulness on continuous customer acceptance in Internet banking. To achieve the goal, we develop the extended Technology Acceptance Model(Ex-TAM) based in the theoretical backgrounds of the Technology Acceptance Model(TAM). To test the new model(Ex-TAM), path analysis is performed by AMOS 4.0 package as a statistical tool. The finding indicate that 4 factors(service characteristics, ease of use, usefulness, trust) are significant. However, 2 factors(security, perceived risk) are not significant, user knowledge is partly significant.

In this paper, an error tracking platform is designed for enhanced-reliable IOT system. The platform is designed to enhance reliability of IOT system by analysing additional informations(OS, Browser, Device) and by notifying error detection to developers. Especially, in the case of an error in the service which it is difficult for developers to recognize it, The platform also supports notification services through various communication media(Email, Slack, SMS). The common interface is designed to accommodate many languages(typescript, Swift, and Android) in the development process, and the interface allows users to analyze errors that occur on various platforms, including mobile/web/desktop applications. By presenting each error in groups through issues, developers can easily identify issues in the service. The visualizing function is included to recognize various error type by dashboard.

Despite the rapid increase in the use of mobile Internet, only a few studies examined digital divide issues in the mobile internet environment. Prior studies on digital divide mainly focused on the usage environments of consumers. The present study analyzes mobile digital divide by considering user environments and the cognitive values of users. Therefore, we estimated the cognitive value of users in mobile Internet environments through contingent valuation method (CVM). We also analyzed the digital divide factors that cause this value difference. We found that domestic users perceive mobile Internet value up to 51,723 Korean Won per month. We analyzed the value differences of digital divide factors, such as "accessibility," "competency," and "usability." Based on this analysis, we found that a difference of 31,878 Korean Won was generated due to accessibility. Competitiveness resulted in a difference of 7,736 Korean Won, whereas that of usability resulted in 6,463 Korean Won. Accessibility is the most important digital divide factor that maximizes the difference of cognitive value of users in a domestic mobile Internet environment.

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.
