  • 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.

  • Roaming authentication protocol is widely used in wireless network which can enable a seamless service for the mobile users. However, the classical approach requires the home server's participation during the authentication between the mobile user and the foreign server. So the more the roaming requests are performed the heavier burden will be on the home server. In this paper, we propose a new roaming authentication framework for wireless communication without the home server's participation. The new roaming authentication protocol in the new framework takes advantage of the ID-based cryptography and provides user anonymity. It has good performance compared with the roaming authentication protocols whose authentication do not need the home server's participation in terms of security and computation costs. Moreover, a new User-to-User authentication protocol in the new framework is also present. All the authentications proposed in this paper can be regarded as a common construction and can be applied to various kinds of wireless networks such as Cellular Networks, Wireless Mesh Networks and Vehicle Networks.

  • As one of the most popular forms of social commerce, on-line social commerce can provide many benefits for consumers, such as lower prices, information sharing, and so on. This research attempted to compare the differences of social commerce participation behavior between Korean consumers and Chinese consumers. The paper also studied the effect of demographic factors and individual propensities on consumer's participation behavior, such as the need for cognition, innovativeness, interactivity, reliability, groupism, and price consciousness. The results and conclusions of this research are as follows. First, consumer's individual propensities are different between China and Korea. In general, Korean participants have a higher level of innovativeness and price consciousness and a lower level of groupism than Chinese participants. Second, the influential factors of social commerce website visiting frequency and the participation in social commerce are different between the two countries. In Korea, consumer's age, innovativeness, and price consciousness have evident effects on the visiting frequency of social commerce websites. While in China, consumer's education, job, innovativeness, and groupism are significant.

  • Proof of Work (PoW) based blockchains have limitations in throughput, time consumption, and energy efficiency. In these systems, a miner will consume significant time and resources to obtain a reward for contributing to the blockchain. To overcome these limitations, recent research on blockchains are focused on accelerating the speed, scalability, and enhancing the security level. By enhancing specific procedures of blockchain system, the level of data integrity supported by the blockchain can become more robust, and efficient. In this paper, a new blockchain consensus model based on the Bryllite Consensus Protocol (BCP) is proposed to support a hyper-connected massively multiplayer online game (MMOG) ecosystem. The BCP scheme enables users to participate directly in new consensus processes through a Proof of Participation (PoP) algorithm. In this model, the consensus algorithm has a simpler form while maintaining high security level. In addition, because the BCP scheme gives users an equal chance to make a contribution to the blockchain, rewards are distributed in an equal fashion, which motivates user participation. The analysis of the proposed scheme is applied to the Bryllite consortium blockchain system (homed in Hong Kong), which is a new blockchain network developed for international game industries, gamers, and game events.

  • Harmonic resonance exists in grid-connected inverter systems. In order to determine the network components that contribute to harmonic resonance and the composition of the resonant circuit, sensitivity theory is applied to the resonance characteristic analysis. Based on the modal analysis, the theory of sensitivity is applied to derive a formula for determining the sensitivities of each network component parameter under a resonance circumstance that reflects the participation of the network component. The solving formula is derived for both parallel harmonic resonance and series harmonic resonance. This formula is adopted to a 4-node grid-connected test system. The analysis results reveal that for a certain frequency, the participation of parallel resonance and series resonance are not the same. Finally, experimental results demonstrate that the solving formula for sensitivity is feasible for grid-connected systems.
