Recently, with coming of various channels, the public are communicating with unspecified massive consumers through personal broadcasting. It is becoming more popular as a positive response. The purpose of this study is to investigate the effect of characteristics of personal broadcasting contents on perceived value, perceived value on continuous use intention and the interaction effect of novelty seeking. As a result of verifying the effects of information quality, information trust, and entertainment on the perceived value, the characteristics of personal media contents all showed a significant positive effect and perceived value has a positive effect on continuous use intention. But The interaction effect of novelty seeking and perceived value is not significant. Therefore, content creators should make efforts to create content as much as to the trust of content as entertainment elements in content and composition. In the future, it will be meaningful to proceed with the research on the direct effects of the novelty trend and the various factors affecting viewers' characteristics using personal media contents.

This study aims to explore and understand better how consumers' value orientation relates to consumer's intention to use and Word-of-Mouth behaviors in using Web sites. Consumers have perceptions of the shopping value they acquire during their experiences in navigating Web sites. This consumer's shopping value is considered as utilitarian shopping value, information shopping value, and hedonic shopping value. The current paper proposes that value orientation of consumers in Web sites would consequently affect consumer attitude such as intention to use and Word-of-Mouth. In addition, the research investigates the moderating effect of consumer's personality between consumer's shopping value and consumers' attitude in Web sites. For testing the hypothesized research model, survey and Lisrel analysis are conducted. The findings emphasize that online providers need to focus on the perceived values most salient to consumers in order to improve their profitability. Furthermore, providers may also identify the reason why consumers perceive these values much lower when using the Web sites.

In this paper, an orthogonal matching pursuit (OMP) method combined with genetic algorithm (GA), named GAOMP, is proposed for sparse signal recovery. Some recent greedy algorithms such as SP, CoSaMP, and gOMP improved the reconstruction performance by deleting unsuitable atoms at each iteration. However they still often fail to converge to the solution because the support set could not avoid the local minimum during the iterations. Mutating the candidate support set chosen by the OMP algorithm, GAOMP is able to escape from the local minimum and hence recovers the sparse signal. Experimental results show that GAOMP outperforms several OMP based algorithms and the $l_1$ optimization method in terms of exact reconstruction probability.
