As digital convergence evolves, it is expected that the market of IP-based services like VoIP and IPTV will be expanded. In particular, IPTV market is expected to attract consumers' attention through various interactive services offering a variety of experiences to consumers. Interactivity sets apart old media from new one in terms of how to mediate effects of user satisfaction. The object of this study is to investigate (1) multi-dimensional Interactivities in an interactive medium based on IP and relationship among them, and (2) significant factors affecting cognitive absorption of interactive media users. This study aims to provide implications on how to develop strategies for IP-based media including e-learning system.

분산 가상 환경(DVE)의 사용자 수가 증대됨에 따라, 고려해야 할 사항 중 가장 중요한 것들 중 하나는 상호작용의 성능을 위한 확장성에 있다. DVE의 확장성을 지원하기 위한 방법들 중 하나는 사용자 인지도 관리 기법이다. 기존의 인지도 관리 기법은 사용자의 인지도를 일정한 공간으로 제한을 함으로써 사용자가 받는 메시지의 수를 줄이는 방법이다. 하지만 많은 사용자들이 근접한 곳에 운집한 경우, 사용자는 그 근접한 공간에서 발생하는 모든 메시지를 받아야 한다. 이것은 사용자들에게 통신에 따른 많은 부하가 걸리게 되며 따라서 시스템은 확장성이 떨어지게 된다. 본 연구에서는 각 사용자의 인지도 영역에 사용자가 관심 있는 사물의 타입을 표현하고 같은 관심을 가지고 있는 사용자들끼리 그룹을 생성하여 사용자의 관심도에 따른 선택적인 메시지를 받게 한다. 이를 통하여 각 사용자는 자신과 근접한 공간에 있는 모든 사용자로부터 생성되는 모든 메시지를 받지 않아도 된다. 본 연구를 통하여 확장성 있는 방법으로 사용자간의 상호 작용을 지원할 수 있다.

Web2.0 이라는 인터넷 환경의 변화 속에서 사용자들의 자발적인 참여를 통해 생산된 컨텐츠(UCC)가 화두가 되고 있다. 다수의 사용자 참여는 집단지성을 발휘하고 이렇게 생성된 UCC 는 새로운 가치를 창출한다는 믿음이 확산된 가운데, 사용자는 더 이상 정보수용자의 입장이 아닌 정보제공자의 입장에서 컨텐츠 생성에 대한 범위와 역할이 크게 향상되고 있다. 그렇다면 과연 무엇이 이러한 사용자 생성 컨텐츠의 창의성에 가장 큰 원동력이 될까 또한 무엇이 집단지성, 집단의 창의성을 창출하는데 가장 큰 영향을 미칠까? 본 연구는 이러한 의문에서 출발하였다. 이와 같은 연구 문제를 해결하기 위하여 피드백과 동기 그리고 창의성에 기반한 인지 평가 이론과 창의성에 관한 사회적 특성이론에 근거, 상호작용 즉 컨텐츠에 대한 피드백을 기반으로 연구모형을 세우게 되었다. 이러한 연구 모형을 설문을 통해 검증해 본 결과, 피드백이 사용자의 동기에 긍정적인 영향을 미치고, 결국 그러한 동기가 개인의 창의성 및 집단 창의성에 긍정적인 영향을 미친다는 결론을 얻을 수 있었다. 이러한 연구 결과는 이론적으로는 인지 평가 이론의 확장 적용 및 CSCW 환경에서 암묵적으로 인식된 피드백과 같은 상호작용의 중요성을 공고히 하는데 기여할 수 있으며, 실제로는 이러한 피드백 요소를 시각적으로 적절히 배치 및 노출하여 사용자의 내적 용기와 창의성을 촉진하여야 함을 밝힌다는데 의의를 가질 수 있겠다.

This study investigated the structural relationships among infant's cognitive and communication ability, temperament, teacher-infants interaction, and mothers' parenting stress. Subjects used in this study were 249 infnats whose mean age of 30.21 months, and who were attended in preschool in S city. Research instruments used in collecting data were 'K-ASQ(Korean Ages and Stages Questionnaires)', 'EAS(Emotionality, Activity, and Sociability-Temperament Survey for Children-Parental Ratings)', 'PSI/SF(Parenting Stress Index/ Short Form)', 'ECOI'. The collected data were analyzed through SPSS 18.0 and AMOS 18.0 program. Pearson's correlation and Structural equation model analysis were used to analyze the data. Findings are as follows. First, there were positive correlations between infant's cognitive and communication ability with social-ability temperament, teacher-infants interaction. There were negative correlations between infant's cognitive and communication ability with infant's emotionality temperament, mothers' parenting stress. Second, social-ability temperament directly affected disposition toward cognitive ability, but in-direct effect was not significant. Emotionality temperament partially mediated the effects of parenting stress toward cognitive ability. Third, social ability directly affected disposition toward language ability, but in-direct effect was not significant. There has no significant path of temperament to teacher-child interaction, but teacher-child interaction has direct effect to infant's cognitive ability. Finally, all path about infant's communication ability were not significant.

The purpose of this paper is to recognize and embody the implications of the concept of interactivity. Among the many types of interactivity already proposed, this paper sheds light especially on the so-called contingent interactivity. The contingency means a condition in which a particular performance or selection of a subject is considered neither necessary nor conclusive, and also the potential for various activities of this subject. The contingent interaction comes into being when the involvements of users in dealing with a message or content are experimental or creative. The interaction does not orient toward the completion of content or the immersion to a particular reality. Rather, the results of a user's contingent performance are not the finalized content and have characteristics that lead to the continuous modification. In order to embody this meaning of contingent interactivity, the paper examined the two example, the film re-cut and game modding. In both cases, it is comprehensive that the user of these two new media activities lies in the contingent situation.

The objectives of this study was to examine the effect of Interactive Video Game on cognitive information processing the elderly. Sixty elderly were attended in this study. Their ages ranged from 65 to 70, with a mean age of 67.60 years. The subjects were randomly assigned to one of three experimental conditions: (1) interactive video game group (n=20), (2) aerobic exercise group (n=20), (3) control group (n=20). The experimental design of this study was analyzed using two-way ANOVAs with repeated measures of groups and time. Cognitive function was assessed by neuroelectrical response, and ERP analysis. The results of the study showed that the interactive video game group and aerobic exercise group showed no significant statistical differences in the response time, response accuracy, amplitude and potential of the performance of the exercise in cognitive function and ERP analysis, but improved the interaction video game group and aerobic exercise (walking) group over the control group. It was concluded that long-term aerobic exercise like interactive video game is associated with attenuation of cognitive decline in the elderly.

This study aims to examine how visitors in science centers interact with gesture-based exhibits from embodied cognition perspectives. Four gesture-based exhibits in two science centers were selected for this study. In addition, we interviewed a total of 14 visitor groups to examine how they perceived the property of gesture-based exhibit. We also interviewed four experts to further examine the benefits and limitations of the current gesture-based exhibits in science centers. The research results indicate that the total amount of interaction time between visitors and gesture-based exhibits was not high overall, implying that there was little of visitors' immersive engagement. Both experts and visitors expressed that the current gesture-based exhibits tend to highlight the novelty effect but little obvious impacts linking gestures and learning. Drawing from the key findings, this study suggests the following design considerations for gesture-based exhibits. First, to increate visitor's initial engagement, the purpose and usability of gesture-based exhibits should be considered from the initial phase of design. Second, to promote meaningful interaction, it is important to sustain visitors' initial engagement. For that, gesture-based exhibits should be transformed to promote intellectual curiosity beyond simple interaction. Third, from embodied cognition perspectives, exhibits design should reflect how the mappings between specific gestures and metaphors affect learning processes. Lastly, this study suggests that future gesture-based exhibits should be designed toward promoting interaction among visitors and adaptive inquiry.

This study was conducted to empirically analyze the factors influencing the intention to continue using live commerce, which was active as digital contacts become more prevailed due to the progress of the 4th industrial revolution and the COVID-19 pandemic. A research model was established by paying attention to the characteristics of influencers among various influencing factors. Influencer characteristics were subdivided into attractiveness, professionality, awareness, and entertainment. In addition, the dual mediating effect of interaction and trust was also tested between influencer's characteristics and the intention to continue using of live commerce. To this end, a survey was conducted targeting people who have experience using live commerce, and 300 valid samples were analyzed. The empirical analysis utilized SPSS 25.0 and Process Macro 4.0. As a result of the empirical analysis, it was found that attractiveness, professionality, awareness, and entertainment derived from the characteristics of influencers all had a significant positive (+) effect on the intention to continue using live commerce. The impact of the influence of variables that directly affect the intention to continue using was in the order of entertainment, awareness, professionality, and attractiveness. On the other hand, as a result of examining the dual mediating effect of interaction and trust, it was found that they all tested a mediating role between attractiveness, professionality, awareness, entertainment, and intention to continue using live commerce. Based on these research results, the academic and practical implications of this study were presented.
