This study examines determinants of film consumption. Using structural equation modelling, this study explores some factors that explained film consumption based on film tastes and information seeking and socio-demographic factors. The major results are as follows: firstly, the major factor for explaining film consumption was individual tastes for films. The higher the degree of tastes for films, the greater the degree of film consumption. Secondly, there were significant relationships between tastes for films and film related information seeking such as internet search behavior and the use of film blogs. More specifically, the use of film blogs partially explained the degree of film consumption. Thirdly, a demographic factor like gender was highly correlated to film consumption. However, an income factor was not correlated to fim consumption. In conclusion, the degree of film consumption was determined by tastes for flims, the use of film blogs and gender factors.

The research for exchange relationship in customer's perspective is meaningful especially in service, considering distinctive characteristics of service operations such as customer participation in the process whereas most of the recent related researches have been focused on employee's interaction with organization, leader, team and customer. In this study for beauty art service, the exchange party's characteristic is defined with beauty salon's reputation, staff's professionalism and customer's self-esteem. Also the exchange relation perception is classified into symbolism and interaction, Then the directional relations on customer's perspective are empirically investigated in the sequential order of the exchange party's characteristics, the exchange relation perception, the relationship quality and behavioral intention. In addition, the study examined the meditation effect via relationship quality between the exchange relation perception and the behavioral intention. Followings are confirmed from the statistical test with structural equation modelling：Symbolism is significantly caused by all of professionalism, reputation and self-esteem in the descending order of effect size whereas interaction is significantly influenced by only professionalism. The exchange relation perception has significant effect on the relationship quality, in turn which significantly affects behavioral intention. The exchange relation perception shows the significant indirect effect meditated by relationship quality and the insignificant direct effect on behavioral intention. This paper concludes with contribution of this study, managerial implication of the research findings and further research issues.

This study is an empirical analysis on the relationship between social presence and online community users' continuance intention. Based on Bhattacherjee(2001)'s expectation-confirmation model (ECM) of IT continuance model, we test the influence of social presence on one's intention to continue using online communities. This study sampled 132 online community users. Research hypotheses are tested using the structural equation modelling(SEM) approach. The results of this study demonstrate that user satisfaction is influenced by perceived usefulness and perceived enjoyment. But, the confirmation of expectation did not affect user satisfaction. And, social presence has direct effects on perceived usefulness and perceived enjoyment. Further, social presence has a positive effect on users' continuance intention through mediating effect of perceived usefulness. This study suggests that perceived usefulness should be taken into account when carrying out the operating strategy of online communities.

In this study, an analysis was conducted to investigate the process how information technology(IT) quality affects organizational performance. Acquisition of IT by itself is not sufficient for the improvement of organizational performance, which additionally requires the operations activity using IT to meditate between IT and organizational performance. This study classified the IT quality into functional quality and operational quality. The functional quality is defined as intrinsic characteristics of IT itself while the operational quality is defined as effective support of IT for organizational management activities. Our research model proposed that the functional quality has indirect effect meditated by the operational quality on organizational performance. The statistical test using structural equation modelling in empirical research showed insignificant direct effect and significant indirect meditation effect of the functional quality on organizational performance via the operational quality. This paper concludes with contribution of this study, managerial implication of the research findings and further research issues.

Functional neuro-connectivity is one of the main issues in brain science in the sense that it is closely related to neurodynamics in the brain. In the paper, we choose fMRI as a main form of response data to brain activity due to its high resolution. We review methods for analyzing functional neuro-connectivity assuming that measurements are made on physiological responses to neuron activation. This means that we deal with a state-space and measurement model, where the state-space model is assumed to represent neurodynamics. Analysis methods and their interpretation should vary subject to what was measured. We included analysis results of real fMRI data by applying a high-dimensional autoregressive model, which indicated that different neurodynamics were required for solving different types of geometric problems.
