Recently, negative sides of internet, internet and/or game addiction and unethical behavior over internet, have been largely publicized in our society. There have been numerous studies to explore the problems and solutions, but these lack considering broader set of research variables. Therefore, this research investigated how i) internet users' self characteristics and ii) cognitive characteristics toward internet influence iii) internet addiction and iv) information ethics respectively. Especially, this study focused on college students, more mature beings than elementary, middle and high school students with whom most other researches have dealt so far. Major findings of this study are as follows: (1) Willingness to develop relationships over internet, usefulness of internet use, a degree to perceive the cyber space as real, and a degree to express self over internet have significant effects on disabled life style. Self respect willingness to develop relationships over internet, usefulness of internet use, a degree to perceive the cyber space as real, and capability of using internet have significant effects on the lack of control over internet. Willingness to develop relationships over internet, self control, and a degree to express self over internet have significant effects on the lack of control over internet. 2) Regarding the effects of independent variables(self characteristics and cognitive characteristics) on information ethics through internet addiction factors, self respect self control, a degree to perceive the cyber space as real, and capability of using internet have directly and indirectly significant effects on information ethics through internet addiction. Then we suggested four approaches to reduce the internet addiction and improve the information ethics based on the findings.

Purpose - This study aims to provide a brief understanding of usability and its extended models with TAM as well as identifying additional determinants that had been suggested in previous studies on mobile services. Research design, data, and methodology - Empirical data were collected by conducting a field survey of potential mobile application service users. The call for participation was also made in mobile related application issues, which were widely discussed. Result - The ease of use and usefulness had a significantly positive influence on attitude and intention. It also was revealed that added value services can offer practical value to customers. Thus, positive attitudes toward the adoption of services by customers are present when they perceive higher usefulness and ease of use of mobile application services. Conclusion - It was indicated that customers who are more inclined to try new products or who have a higher demand for new things tend to think about those functionalities and added value mobile application services from the perspective of usefulness and ease of use and operation.

This study aims to examine factors influencing the intention to continue using the metaverse, focusing on the impact of social norms. Specifically, direct and indirect effects of technical characteristics (perceive quality, interactivity, perceived playfulness), user characteristics (self-efficacy, personal innovativeness), and social influence factors (descriptive norm, injunctive norm, subjective norm) on continuous use intention were examined. The role of perceived ease of use and perceived usefulness as a mediator was also examined. An online survey was conducted with 165 college students attending universities in two large cities in South Korea who had used the metaverse. As a result, perceived playfulness, descriptive norm, and perceived usefulness directly influenced continuous use intention. Perceived playfulness, interactivity, and subjective norm influenced continuous use intention indirectly through perceived usefulness. This study theoretically extends the Technology Acceptance Model by specifying social influence in metaverse contexts. Practical implications are provided in terms of marketing strategy for the metaverse industry to continue to grow and develop.

본 연구는 1)개인의 운동/피트니스 앱 속성에 대한 인식과 2) 운동/피트니스 행위에 대한 동기가 앱에 대한 유용성 인식 및 앱 활용에 어떠한 영향을 미치는지 살펴보았다. 운동/피트니스 앱을 이용하는 20-30대 남녀 323명을 대상으로 조사한 결과, 기본심리욕구를 충족시킬 수 있는 앱의 속성이 이용자들로 하여금 앱의 유용성을 인식하도록 만드는 중요한 요인인 것으로 나타났다. 즉, 사용하고 있는 운동/피트니스 앱이 자율성 및 유능성 관련 속성을 갖고 있다고 인식할수록, 해당 앱을 더욱 유용하게 평가하는 경향이 있었다. 관계성 관련 속성 인식은 앱 유용성 인식에 주효과는 없는 것으로 나타났으나, 개인의 운동에 대한 자율적 동기와 상호작용효과가 나타났다. 또한 이들 기본심리 욕구와 관련된 속성에 대한 인식은 인식된 유용성을 통해 간접적으로 앱 활용에 영향을 미치는 것으로 나타났다. 건강앱이라는 정보기술을 심리 및 보건학의 융복합적 관점에서 연구한 본 연구의 이러한 결과는 건강앱 개발 및 평가에 관한 실무적 함의를 제공한다.

The use of mobile office systems has been expanded due to the smartphones' rapid diffusion in Korea, and it has brought a new work environment that is different from traditional working patterns. In this study, the unique attributes of mobile office systems, such as ubiquity, usefulness, complexity, and insecurity, are examined along with the impact of these attributes on work overload and job stress. Based on transaction-based model of job stress, organizational support was applied as a stress inhibitor and also the moderator between work overload and job stress. The findings of this study show that ubiquity increases usefulness of mobile office systems; complexity increases both work overload and job stress; and insecurity increases job stress. Surprisingly, usefulness increases job stress, which means employees who perceive the efficiency of mobile office systems higher may feel more job stress. Organizational support for mobile office systems significantly shows the moderating effect, but no direct mitigating effect on job stress. The theoretical and practical implications in order to mitigate the side effects of mobile office systems based on the research findings are thoroughly discussed.

본 연구는 대학생이 지각하는 팀 프로젝트 기반 학습법에 대한 유용성과 학습만족도 간의 관계를 규명하고 지각된 자율성, 협력적 효능감, 인지된 상호작용성이 지각된 유용성에 미치는 효과를 탐색하였다. 이를 위해 경기도 소재 대학생 55명이 한 학기 동안 팀 프로젝트 기반 학습을 완료 후 설문조사에 참여하였다. 본 연구의 결과는 다음과 같다. 첫째, 팀 프로젝트 기반 학습법에 대해 지각된 유용성이 높을수록 학습만족도가 높게 나타났다. 둘째, 지각된 자율성과 협력적 효능감을 높게 인식할 때 학습법에 대한 지각된 유용성을 높게 인식하였다. 이와 같은 연구결과는 대학의 팀 프로젝트 기반 학습법 설계 시 학습자가 학습법이 효율적이고 유용하다고 느끼게 하는 것이 중요하며 이를 위해 자율성을 지지하는 환경조성과 학습자가 협력하여 공동의 목표를 성취할 수 있는 능력을 충분히 갖췄다고 느낄 수 있는 전략이 필요함을 시사한다.

Purpose This paper attempts to explain the recent expanding trend in Mobile Grocery Shopping(MGS). More specifically, the authors have applied the Post Acceptance Model(PAM) in order to examine the conceptual structure among the four constructs of 'Expectation Confirmation', 'Perceived Usefulness', 'User Satisfaction', and 'Continuance Intention to Use' in Mobile Grocery Shopping. Design/methodology/approach Through a survey agency, data were collected from a sample of 312 consumers who had the previous experience in Mobile Grocery Shopping. The Structural Equation Modeling(SEM) analysis was conducted with the survey data using AMOS 22.0. Subsequently, 8,200 real customer data from an open market site were collected in order to find out their revisit and repurchase behavior. Findings This study supported the causal relationships of Expectation Confirmation → Perceived Usefulness, Expectation Confirmation → User Satisfaction, Perceived Usefulness → User Satisfaction, and User Satisfaction → Continuance Intention to Use, but did not support the direct effect of Perceived Usefulness on the Continuance Intention to Use Mobile Grocery Shopping. This implies that consumers with any experience in Mobile Grocery Shopping would not consider repurchase, unless they are satisfied with the experience even though they perceive its usefulness. Also, Expectation Confirmation has much larger effect on User Satisfaction than Perceived Usefulness. In addition, the real customer data showed that the revisit and the repurchase rate of mobile grocery shoppers were higher than those of online grocery shoppers, although the rates of adding to shopping carts, coupon downloads, and adding to favorites are similar.
