Social Network Service (SNS) has been played an important role in the life with the expansion of the modern technology in the cellular communication. More knowledge and understanding should be inevitable even if companies have taken advantage of SNS through word of mouth as one of the new paradigm. In most cases the crucial benefit or peculiarity of SNS has been overlooked because only general aspects of SNS have been applied in the online situation. As a result of this, same paradigm has been considered in reality as SNS was just used one of the marketing tools. However, essential aspects of SNS were investigated to see the relation of usage intention and word of mouth in this study. The hypothesis of the effect of continuous intention of the usage, trust and word of mouth was made and reviewed statistically. The statistical analysis showed there was significant among relationship, context, perceived service quality and continuous intention of the usage. In addition to that, self-expression, relationship, perceived service quality and trust were significant. Finally the continuous intention of the usage and word of mouth was significant as well. Based on this study, SNS provided by the companies could be effective to the customers in terms of word of mouth while different trend was shown in terms of trust.

Supply chain management (SCM) aims to provide the coordination and execution of planning and decision-making in multi organization-wide production and distribution. The advancement of information technology and the globalization of market promote SCM integration. Information sharing has become a major driver of competitive advantage in SCM. In this research, we aim to analyze the influence of SCM integration on firm performance and the role of information sharing between SCM integration and firm performance. Of the 750 questionnaires posted, a total of 218 questionnaires were collected after one follow-up. A total of 199 questionnaires were analyzed after 19 questionnaires were eliminated due to largely missing values. We used structural equation modeling technique to validate the causal relationship between SCM integration, information sharing, and firm performance. The results suggest that improved SCM integration both within the focal company (intra-organization) and across companies (inter-organization) enhances firm performance positively. Information sharing acts as a mediator between the SCM integration and the firm performance. Intra-organization SCM integration is positively related to inter-organization SCM integration, namely, SCM integration with suppliers and customers. The results suggest that internal integration of SCM significantly influences external integration with customers and suppliers. The result also shows that supply chain integration has a positive influence on firm performance and information sharing positively impacts firm performance as well.

This study empirically investigated the relationships among organizational culture, target costing, knowledge management activities, and corporate innovations. The results of this study showed that innovative and supportive culture positively affects the adoption degrees of target costing. According to the results, it was observed that target costing as well as innovative and supportive culture have a positive impact on levels of knowledge management activities(i.e., knowledge creation, sharing, storage, and application). It was also demonstrated that organizational culture has an indirect effect on activation of knowledge management activities through target costing. Thus, to enhance knowledge management activities, target costing must be aligned with appropriate types of organizational culture. In examining the impact of knowledge management activities on the frequencies of product and process innovations, no significant effect was found. Additional analyses that compare across three groups(i.e., low level group, middle level group and high level group in knowledge management activities) and between two groups(i.e., between high level group and middle level group or between high level group and low level group) were performed. The results of comparison showed that the degrees of product and process innovations are highest in high level group, but no significant differences are found in the degrees of innovations between middle level group and low level group.

With the active smartphones user exceeding 500 million by the end of 2014, China has now become the largest smartphone market in the world. Smartphone companies provide variety of information through a range of applications, such as communications, entertainment, games, and so on. There were many studies conducted about the user acceptance and continuous intention of mobile service. However, it is still not quite clear what factors attract people to reuse smartphone in China. This paper examines the continuous intention of smartphone about Chinese customers. This study incorporates perceived enjoyment as a additional construct into a extended TAM model, by integrating a hedonic service of smartphone. We propose a research model that reflects the individual characteristics and usage contexts of smartphone, such as innovativeness, social influence, and service quality, and analyze the structural relationship between the main variables through empirical study. This study empirically investigated a research model and conducted a survey of smartphone service users in China. Our study proved that perceived enjoyment has a positive influence on continuous intention to use smartphone services. This paper provides the managers an insight that smartphone companies should take more consideration on how to provide more enjoyable service and attract customers to reuse their services.

Why people reduce or stop using social network services(SNS), which are regarded as a mean of relationship and communication, unlike the early trend? To explain the phenomenon, this study tries to predict psychological decision making process of users from perspectives of cognitive dissonance theory. From this perspective, this study attempted an integrative approach that reflected 'User's literacy' indicating the ability of individuals to use SNS, and 'negative mass media influence' such as media reports on side effects or the bad experiences of acquaintances, along with the 3 factors used in the SNS Prior research. This study conducted an empirical analysis by surveying 256 facebook users, and the major findings are as follows:- First, Social-overload, complexity, uncertainty and negative media influence are significantly affect dissonance on the use of SNS. Second, Dissonance on the use of SNS significantly affects the behavior that possibly reduces and limits the use of SNS. In other words, the users who have experienced psychological dissonance respond passively by avoiding the use of SNS to resolve the dissonance. Third, the moderating effect of User's literacy wasn't a significant. This study presents a clue to understand psychological decision making process of use of SNS and a guideline for establishing practical strategies. In addition, it is important to note that this study contributes to expansion of theoretical discussion about usage.

Green supply chain management(GSCM) has emerged as an organizational system which helps organizations and their parter to achieve corporate profit by reducing environmental risk and cost. The main objective of this study is to investigate the relationship among organizational factors(manager support and organizational learning), GSCM practices(investment recovery and eco-design) and GSCM performance based on the BSC. Using a sample of 125 Korean companies, path analysis is used to test the research model. The results shows that the manager support has a positive effect on the investment recovery and eco-design. The results also suggest that the organizational learning directly affect the investment recovery, but do not affect the eco-design. The investment recovery and eco-design have effect on the GSCM performance. In addition, the competitive pressure has moderating effects on most of the relationships between the organizational factors and GSCM practices. This findings provides useful insights for managers seeking to adopt GSCM practices, and also provide useful guidelines for researchers to study GSCM performance.
