The main purpose of this study is to understand how the characteristics of social network services' social group can impact customer satisfaction, trust and repurchase intention. For this, this study extracts five social group factors(word of mouth effect, social interaction, collectivism, variety seeking, information seeking) based on relevant literature reviews. In addition, the study examines the moderating effects of utilitarian value on the relationships between customer satisfaction and trust and intention to repurchase. The proposed model of this study is empirically tested using survey data collected from 220 social commerce users. The results indicated that social group factors except social interaction were positively related to customer satisfaction. In addition, social group factors except social interaction and information seeking were positively related to trust. The results also showed that customer satisfaction and trust had a significant influence on intention to repurchase. The moderating effects of utilitarian value also was significant. The results of this study presented the strategic implications for social commerce firms.

By virtue of the development and widespread of social network services, the importance of SNS for an individual's social capital formation as well as people's act of sharing information is increasingly highlighted. However, there are still few empirical studies on successful formation of SNS, people's attitude towards participation in SNS, and the brisk act of sharing information in the SNS as yet. This study performed an analysis that, in terms of forming the successful SNS, people's attachment to the group in SNS induces the attitude towards the participation in SNS, and the information-sharing act on the basis of the socio-psychological theory. For this purpose, this study carried out empirical study by dividing the influential factors into the attachment to online group, and attachment to the members in SNS group on the basis of trust. This study set up the component factors in trust as high-dimensional factors, and used SPSS 18.0 and SmartPLS 2.0 as analysis tools. Analysis results confirmed that group formation in SNS and people's attachment to the group were significantly influence attitude towards participation in SNS as well as information sharing behavior. This result implies that group formation in SNS plays an important role in active use of SNS.

Personal creativity is critically important for organizations seeking to survive and thrive in today's highly turbulent business environments. Organizations must effectively identify and mobilize the creative resources of their members. When organizational members perceive a work environment that restricts or fails to encourage individual creative expression, a gap may exist between the level of individual creative potential and the actual amount of individual creativity practiced within the organization. In this situation, this paper will examine the impact of role conflict, role ambiguity, creative self-efficacy, and personal initiative on personal creativity. Creative self-efficacy is the subjective belief in one's personal ability to be creative, that is, a personal assessment of one's own creative potential. A strong internal belief in one's ability to successfully engage in creative behaviors is generally considered an important part of the creative process. Personal Initiative refers to behaviors, mainly directed toward work and organizational issues, that are characterized by the following aspects: self-starting, proactive, and persistent in overcoming barriers. Creativity-related creative self-efficacy and personal initiative are critical components to understand motivation that coordinates the relationship between perception and behavior of individual employees. Based on role theory, researchers have focused on role conflict and role ambiguity as the two key ingredients of role stress. Role ambiguity is defined as an evaluation about the lack of salient information needed to perform a role effectively. Role conflict results from two or more sets of incompatible demands involving work-related issues. Employees are usually pursued work-roles more than one in work-focused organization. Too many work-roles and perceived uncertainties at employee's work can be obstacles to personal creativity. In an analysis of results, while role conflict is not negatively related significantly to creative self-efficacy, role ambiguity is negatively related significantly to creative self-efficacy. While role conflict is significantly related to personal creativity, role ambiguity is negatively related significantly to personal creativity. Creative self-efficacy mediates the relationship among role conflict, role ambiguity, and employee creativity. Personal initiative mediates the relationship between creative self-efficacy and employee creativity. This paper shows that creative self-efficacy and personal initiative are the driving force behind personal creativity. Organizations can get some implications of creative-related role conflict and role ambiguity that employees have experienced. As a result, organizations must not only encourage creativity of employees by greater involvement but also encourage their input towards their-focused own works and tasks. And employees should be developed to pace with the organizational needs and development. Management must enable employees to think of new ideas and practices that promotes personal creativity.

최근 클라우드 컴퓨팅이 학계나 실무계에서 많은 주목을 받고 있으며, 공공기관에서도 클라우드 컴퓨팅을 도입하고 있는 추세에 있다. 클라우드 컴퓨팅은 장 단점을 모두 가지고 있지만 지속적으로 발전하고 있으며, 기업들은 클라우드 기반의 정보시스템을 도입하기 위한 다양한 솔루션들을 활용하고 있다. 따라서 기업에서 클라우드 컴퓨팅 도입을 위해 고려해야 할 요소들은 무엇이며, 어떻게 계획을 수립할 것인지는 시급한 과제라고 할 수 있다. 본 논문의 목적은 기업이 클라우드 컴퓨팅 채택 전략을 수립하기 위한 프레임 워크를 제시하는 것이다. 구체적으로, SWOT-AHP는 클라우드 컴퓨팅을 실행하는 과정에서 강점-약점-기회-위협 요인을 파악하고, 전략 계획을 보다 효율적으로 수립 하는데 사용된다. 경영전략 이론에서 널리 알려져 있는 SWOT과 다기준의사결정기법 중 실무에서 가장 활발하게 사용되고 있는 AHP는 복잡하지 않고 적용이 쉽기 때문에 본 연구에서 제안하는 방법을 이용한다면 실무에서도 큰 어려움 없이 SWOT-AHP 프레임워크를 클라우드 컴퓨팅 전략수립에 적용할 수 있을 것으로 기대한다.

Recently, since the interest with well-being has been getting higher than ever, people want reliable source of information related with health and medical treatment. Because of the characteristics of information related with medical care, there have been difficulties to find the information from books, television and internet surfing, for treating disease.
