While earlier research reports focused on Internet addiction among adolescents, this research examines the direct/indirect impact of socio-psychological variables like stress level, self-consciousness (self-esteem, self-control, and self-efficacy), and Internet use control on Internet addiction among adults. The fact that 62.4% of survey respondents were diagnosed as Internet addicts demonstrates that this concern about Internet addiction among adults is valid. This research, first, shows the direct impact of socio-psychological variables on Internet addiction. Low self-esteem, low self-control, high self-efficacy, high levels of stress, and high Internet-use control lead to a severe level of Internet addiction. Second, self-consciousness variables mediate the impact of stress on the addiction, but the mediating role is not so significant as the direct impact. Internet-use control plays as a partial moderator between self-esteem, self-control and addiction. Internet-use control is a useful measure for Internet addition at work. In addition, businesses may take personality, as well as environmental conditions, and organizational management process into account to minimize the impact of the addiction.

In this paper, we present an implemented serial 40-Gb/s receiver optical subassembly (ROSA) module by employing a proposed TO-CAN package and flexible printed circuit board (FPCB). The TO-CAN package employs an L-shaped metal support to provide a straight line signal path between the TO-CAN package and the FPCB. In addition, the FPCB incorporates a signal line with an open stub to alleviate signal distortion owing to an impedance mismatch generated from the soldering pad attached to the main circuit board. The receiver sensitivity of the ROSA module measures below -9 dBm for 40 Gb/s at an extinction ratio of 7 dB and a bit error rate of $10^{-12}$.

Recently, internet as well as internet banking are growing rapidly. Most banks in Korea provide internet banking services for customers. Internet banking became a major trend in the financial marketplace. There are a few empirical research in this area. Although quality of internet banking service is an important concept, there is a lack of theory-based empirical research in this area. Therefore, this paper is aimed at finding whether service quality of internet banking influence customer satisfaction, and whether characteristic of internet banking user influence relationship between customer satisfaction and service quality of internet banking. Furthermore, this paper identify whether customer satisfaction influence customer loyalty. The research model proposed thirteen hypothesis and tested empirically. A total of 269 responses were received from internet banking users and analyzed. The analyses showed partial support for the affirmative effect of customer satisfaction and characteristic of internet banking user. But the relationship between customer satisfaction and customer loyalty is significant. Implications of these findings are that internet banking sites should concentrate on providing a high quality of banking services; information, trust, ease of use, and security of system and thereby strengthen customer loyalty.

본 논문에서는 데스크탑에서 실행되는 이동형 개인맞춤 SW 플랫폼 YouFree의 개인용 위젯들을 사용자가 용도로 모아 배포하고 공유하는 시스템을 설계하고 구현하였다. 개발된 시스템에서는 사용자가 외부로부터 위젯 모음들을 다운받아 자신의 작업환경을 구축하거나, 사용자가 생성한 위젯 모음을 다른 사용자가 이용할 수 있도록 공유하는 기능을 제공한다. 따라서 개별적으로 위젯들을 설치하는 것보다 위젯 모음 공유 기능을 통해 더 빠르게 사용자는 자신의 작업환경을 구축할 수 있다.

In this study, there are two research objectives. First, we identified the impact of service quality on customer satisfaction and intention to repurchase in the Internet shopping mall. Second, we tried to analyze the mediating effects of the customer satisfaction on the relationship between service quality and intention to repurchase. Based on past research and theoretical discussions, we developed a research model in terms of service quality and intention to repurchase in the Internet shopping mall. In order to verify our research model, we analyzed 492 survey data of consumers who had experiences in the Internet shopping mall in China. We found that sub-factors of the service quality in the Internet shopping mall have positive effects on customer satisfaction and repurchase intention through the survey data analysis. Among the five factors of service quality in the Internet shopping mall, except assurance, the positive effects of tangibility, responsiveness, empathy and reliability on repurchase intention are statistically significant. In addition, we found mediating effects of customer satisfaction in the Internet shopping mall on the relationship between service quality and intention to repurchase.

This paper proposes an integrated model of customer loyalty in the context of Internet shopping based on a review of two competing perspectives - transactional and relational views. The research model suggests that the usability and trust associated with an Internet shopping site are key determinants of customer loyalty. In this paper, factors such as promotion, ease of use/navigation, and purchase facilitation are posited as major determinants of usability. Trust, on the other hand, is assumed to be influenced by the quality of communication, social shopping service, and safety level associated with an Internet shopping site. This paper also asserts that the lack of consideration for individual differences is one of the key reasons for the inconsistent and mixed research findings in user acceptance literature. In this regard, the elaboration likelihood model (ELM) is considered to be appropriate referent theory as it may theoretically explain why a particular information technology (IT) related message has varying influences on different adopters. The research model comprising 11 hypotheses was derived from and validated through a survey involving 271 university students. The partial least square(PLS) method was used to test the suitability of the research model and its hypotheses. Overall, the results suggest that the usability and trust associated with an Internet shopping site play an important role in acquiring loyal customers. In particular, the user's Internet shopping involvement is found to moderate the relationship between trust and customer loyalty.
