Recently, in the research on online environment such as e-commerce, and internet banking, the conceptual discussion about trust and risk in an effort to explain a user's behavior is briskly underway. Most of the research on trust and risk are setting up causal relationship without clearly establishing the relationship between trust and risk. Accordingly this study conducted a meta-analysis in order to consider the relationship between trust and risk and to take a look at the difference in causal relationship. This study includes a total of 18 research papers which are setting up the causal relationship between trust and risk in online environment among the research papers published in domestic academic journals since 2000. Result of the meta-analysis, showed that the effect size was -0.367 in the path from trust to risk; -0.131 in the path from risk to trust; -0.276 in the bidirectional path between trust and risk. In addition, this study was able to confirm through literature review that there appeared a high effect of path in case where trust and risk were measured by an uni-dimensional concept than by a multi-dimensional concept.

Recently, the topic of predicting interpersonal trust in online social networks is receiving considerable attention, because trust plays a critical role in controlling the spread of distorted information and vicious rumors, as well as reducing uncertainties and risk from unreliable users in social networks. Several trust prediction models have been developed on the basis of transitivity and composability properties of trust; however, it is hard to find empirical studies on whether and how transitivity and composability properties of trust are operated in real online social networks. This study aims to predict interpersonal trust between two unknown users in social networks and verify the proposition on whether and how transitivity and composability of trust are operated in social networks. For this purpose, we chose three social network sites called FilmTrust, Advogato, and Epinion, which contain explicit trust information by their users, and we empirically investigated the proposition. Experimental results showed that trust can be propagated farther and farther along the trust link; however, when path distance becomes distant, the accuracy of trust prediction lowers because noise is activated in the process of trust propagation. Also, the composability property of trust is operated as we expected in real social networks. However, contrary to our expectations, when the path is synthesized more during the trust prediction, the reliability of predicted trust did not tend to increase gradually.

A trust-aware secure routing protocol (TSRP) for wireless sensor networks is proposed in this paper to defend against varieties of attacks. First, each node calculates the comprehensive trust values of its neighbors based on direct trust value, indirect trust value, volatilization factor, and residual energy to defend against black hole, selective forwarding, wormhole, hello flood, and sinkhole attacks. Second, any source node that needs to send data forwards a routing request packet to its neighbors in multi-path mode, and this continues until the sink at the end is reached. Finally, the sink finds the optimal path based on the path's comprehensive trust values, transmission distance, and hop count by analyzing the received packets. Simulation results show that TSRP has lower network latency, smaller packet loss rate, and lower average network energy consumption than ad hoc on-demand distance vector routing and trust based secure routing protocol.

The purpose of this study is to analyze the factor influencing in order to increase the intention to revisit rural experience tourism. 181 men and women who had experienced rural experience tourism were surveyed in a Self-Assessment Questionnaire. Some farming experience, life experience, cultural experience, and leisure experience were set as independent variables as representative programs of rural experience tourism, satisfaction and trust as mediated variables, and relationships as dependent variables. Here, the relationship is regarded as a variable representing the intention to revisit. When performing multi-group path analysis by separating men and women, both men and women had a statistically significant positive (+) effect in the Leisure experience→Satisfaction path and the Trust→Relation path. In addition, the paths that were statistically significant for women were not statistically significant, but were statistically significant only for men were Farm experience→Satisfaction path, Farm experience→Relation path, and Leisure experience→Relation path. In addition, the paths that were not statistically significant for men, but statistically significant for women were Culture experience→Satisfaction and Trust→Satisfaction. According to this study, in order to increase the intention to revisit, both men and women should consider leisure experience. And men should emphasize farming experience, while women should emphasize cultural experience. It is considered that there is a need to further subdivide leisure experience, farming experience and cultural experience for the region. This study has a limitation of only 181 people. More large-scale research will be possible in the future.

Growth in the outsourcing market signals that firms of all sizes believe outsourcing will ultimately deliver many benefits and conveniences. But there are not many firms satisfied with the results of outsourcing. What is more, previous researches were fragmentary analyses focused on specific variables of outsourcing such as sourcing decisions, partnership rather than comprehensive analysis. Thus, they could not propose general systematic methodologies applicable to the real situation. To solve these problems, we developed an integrated theoretical framework that considered both contract with the hard side and trust with the soft side from a contingency viewpoint and tested this model using 143 data of Korean companies executing outsourcing. In addition, we examined how situational factors(outsourcing task complexity and outsourcing management competence) affects each path in the research model. The results of this study are as follows. First, it was proved the theory that trust is not a substitute for contract but its complement. Previous empirical studies on outsourcing success factors were focused on the establishment of successful partnership on the assumption that trust can replace contract in many situations. According to the results of our empirical analysis, however, contract and trust were in a mutually complementary relation with each other and their emphasis was different. Furthermore, different from previous researches, it was found effective to use trust as a supplementary tool and contract as a main means in outsourcing management strategy. Second, this study provided an integrated view that sees both contract and trust from a contingency viewpoint in theoretically reestablishing the relationship between contract and trust. Previous researches leaned to specific variables or theory-centered fragmentary analysis, but this study proposed a more practical and integrated research model and tested its effectiveness. Based on the results, with the model, decision makers are expected to scrutinize outsourcing situation more closely and to have a practical insight to the situation. Third, it was found that contract mechanism and trust building do not have a direct effect on outsourcing performance but relationship management intensity mediates the effect of contract mechanism and trust building. This is considered significantly meaningful to outsourcing partners who have believed that outsourcing would be successful if a contract is made properly or trust is built. Lastly, the path from trust building to relationship management intensity was moderated by informed buying, as the path coefficients from trust building to relationship management intensity varied by the degree of informed buying competence.
