Despite many numbers of studies in Technology Acceptance Model(TAM), the social influence construct has not been recognized, nor handled clearly. This study includes the social influence construct in TAM and tests the robustness of the model for different information systems contexts: office automation(spreadsheet) and Internet(WWW) usage. Study findings include that 1) social influence has a direct impact on the usage of spreadsheet, but not on Internet(WWW) usage, and 2) social influence has a stronger indirect impact on IS use through perceived ease of use than through perceived usefulness(for both Internet and spreadsheet).

Purpose This study aims to analyse the impact of the development of fintech and the emergence of internet primary banks due to the increasing use of smartphones on the performance of traditional local banks from both financial and non-financial perspectives. Return on equity (ROE) and return on assets (ROA) are used to assess the performance differences between the two types of banks and how these differences are affected by their financial characteristics. Design/methodology/approach Using return on equity (ROE) and return on assets (ROA) as indicators, we identified the differences in operating performance between the two types of banks. In addition, this study analysed the impact of financial characteristics on profitability through regression analysis with various control variables. We further studied the impact of non-financial characteristics (customer reviews, social media reactions, etc.) on operating performance. Findings The net interest margin ratio of local banks had a positive impact, while the marketable securities ratio of Internet primary banks had a negative impact. The non-financial analysis shows that the number of customer reviews and social media reactions have a significant impact on the performance of Internet primary banks, suggesting that customer satisfaction and positive market perception are important factors in the performance of Internet primary banks.

Many real networks exhibit overlapping community structures. Recent studies have been performed that analyze the impact of overlapping community structure on information propagation, but few of them concerned with individual behaviors. From this point of view, we propose a Markov process model to evaluate the performance of information propagation in social networks with overlapping community structures. In addition, many individual social behaviors are combined in the model. For example, individuals may exhibit selfish behaviors, such as individual and social selfishness, and people may discard the information after they have used it. The accuracy of the model is verified by simulation. Furthermore, the numerical results show that both overlapping community structure of the network and individual behaviors have a significant impact on the outbreak size and propagation speed of the information. Additionally, the overlapping community structure of the social network can reduce the impact of selfishness on information propagation.

The purpose of this study was to investigate the types of perceived risk of Internet shopping and the impact of perceived risk on purchasing behavioral intention of Internet shopping mall shoppers. A self-administrated questionnaire was e-mailed to INR research (www.inr.co.kr) panel who had purchasing experience of fashion product through Internet shopping mall. The perceived risk was reduced when the innovativeness increased and purchasing experience in Internet shopping mall increased. The financial risk had an effect on purchasing intention, and social/psychological risk had impact on revisiting intention and word-of-mouth intention negatively. The performance risk perception had significantly negative influence on word-of-mouth intention. Internet using time per week, purchasing experience and Internet innovativeness were positive impact on purchasing behavioral intention of Internet fashion product.

As social problems including aging, depopulation, healthcare, poverty, a lot of government, organizations is trying to solve the problems. Recently, social innovation is emerging as strategy for solving social problems around the world. Social innovation means more effective, sustainable and new solutions that increase total values of society. This study attempts to introduce microworks of the Samasource as a case of the business-community innovation model using IT. Samasource is one of three social ventures under the nonprofit organization Sama Group established in 2008. Its mission is to alleviate worldwide poverty by connecting unemployed people in impoverished countries to digital work. Based on the internet model "microwork", they split huge digital projects into small scales, and deliver them to BOP(Bottom Of Pyramid) groups through the internet. This case describes a business model, revenue model, and impact of Samasource's Microwork. Implications of the case were suggested in the conclusion. To this end, I would like to provide a meaningful implication to researchers and founders of the South Korea.

온라인 사회운동 연구에 있어 가장 근본적인 관심사는 인터넷의 확산이 기존 사회운동에 어떤 변화를 가져올 것인가라는 점이다. 연구자들의 관심은 우선 인터넷이 초래하는 운동의 주체와 전략에 대한 변화양상이다. 인터넷의 출현 이후, 지리적으로 산재된 개인들의 수평적 네트워크 혹은 개별 네트워크들이 연합한 네트워크가 운동의 주체로 활동하는 새로운 현상을 낳았다. 또한 일부 연구자들은 인터넷과 사회운동의 결합으로 인해 나타난 '새로운 집단행동 전술 및 전략'에 주목하였다. 온라인 사회운동의 증가는 자원동원, 집단정체성, 그리고 정치적 기회구조 등에 관한 기존 사회운동 이론에 있어도 새로운 해석을 요구하고 있다. 인터넷이 사회운동에 미친 영향, 그리고 그로 인한 변화양상에 대해서는 여전히 많은 논쟁이 진행 중이다. 초기 사이버 낙관론과 회의론 간의 논쟁은 물론이고, 이후 중범위적 시각에서 진행된 연구들 역시 인터넷의 영향력에 대해 서로 다른 입장을 보이고 있다. 이는 무엇보다 온라인 사회운동의 역사가 불과 10여년 밖에 되지 않아 충분한 사례연구와 데이터 축적이 이루어지지 않았기 때문이다. 향후에는 기술진화에 따른 온라인 사회운동의 변화와 비교연구에 더 많은 관심을 둘 필요가 있다. 또한 연구의 시각을 사회운동 내부에만 초점을 둘 것이 아니라 정치체제의 차원으로 확장해, 온라인 사회운동이 정치적 매개집단 그리고 나아가 민주주의 모델에 미치는 영향에 대해 분석할 필요가 있다.

Mobile social network can be seen as a specific application of the DTN (Delay Tolerant Network), in which the information propagation can be impacted by many social behaviors of the nodes. For a specific node, its social behaviors are various. For example, the node may not be interested in the information before receiving it and may also discard the information after getting it. On the other hand, people are more willing to forward the message to his friends. These interactive behaviors between nodes can be seen as social behaviors. It is easy to see that the impact of the social behaviors is related to the social ties, which can be manifested by the structure of the social network. State of the art works often simply assumes that the social networks can be divided into some communities. At present, some works find that the structure of some social networks is scale-free. To overcome this problem, this paper proposes a theoretical model to evaluate the impact of above social behaviors in the DTN-like scale-free network. Simulation shows the accuracy of the model. Numerical results show that both social behaviors and scale-free character have significant impact on information propagation. Moreover, the impact of social behaviors is related to the scale-free character of the networks.

The development of information technology improves the globalization of the world economy. This change was able to expand the cyber space, and the online community known as the cyber community is made within the existing offline community. From the cyber community's activity, the concept of social network services created, and recently developed social computing. Social computing is the current situation and the next step in the online community. Currently, most CIOs are using social computing for workplace empowerment. As online transactions become more active, the strategy to increase customer loyalty in Internet shopping is an effective tool to increase profit for the company, and as a method to maintain competitive. With the growth of electronic commerce, through insurance of customer loyalty on the Internet, a company can establish a long-term relationship with customers, so for this, it is important to have reliable relationship with customers. Also, through advertisement and commercial information, the cognition of Internet shopping looks can be effective in retaining customers. In this study, it explores how social computing and trust and cognition of Internet shopping are effective in maintaining customer loyalty. As the result of study, the trust and cognition of Internet shopping are significantly effective on customer loyalty, but the sense of social computing. Still, social computing has not matured enough to be as effective in retaining customer loyalty. However, it does indicate that social computing has significantly increased the trust and cognition in Internet shopping. In this study, as the concepts of the social network service and social computing are applied in Internet shopping, which are actively discussed by scholars, it is expected that the basis of the study could improve and present the idea of social shopping.

Although the Internet has been a important communication tool in modem societies, researchers did not pay attention to its' positive impacts on individual's psychological process. The Internet provides users with a unique environment such as visual isolation, non face-to-face communication, and easiness to escape from social influences. This environment enables people to take free action according to their personality and disclose themselves. From the uses and gratification perspective, the current research reveals that individuals with high extraversion are inclined to maintain social networking sites and those with high openness participate in web communities. The findings indicate that individuals' social use of the internet may reflect their personality. This study, also, reveals that controlling the big five personality dimensions, the amount of self-disclosure through ones' social networking site is positively related with subjective happiness. This finding suggests that like confession behaviors in religious or curing facilities, people can use the Internet as a therapeutic or a preventative method for promoting their well-being. Theoretical contributions and practical implications are discussed.
