This is a case study on how infants' behaviors change after their child care teachers use Responsive Interactions to them. The participants are five infants and five child care teachers from five employer-supported child care centers run and managed by H foundation. This study analyzes the changes in infants' pivotal developmental behaviors based on interactions between an infant and a child care teacher in video recordings, anecdotal records, Reflective Journal written by the teachers, and data on in-depth interviews with the child care teachers. The results show that Responsive Interactions have brought positive changes to infants' pivotal developmental behaviors(Attention to Activity, Problem Solving Persistence, Involvement, Cooperation, Initiation, Joint Attention and Affect). It suggests that child care teachers who are in charge of taking care of infants should realize and practice the importance of Responsive Interaction Strategy in order to help the infants develop their pivotal behaviors.

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.

One of the key factors for success in fostering web-service is the supply of user-generated contents(UGCs). Technological interactivity is an environmental factor which stimulates user-content interaction, and reflects the system's capability for supporting various interactions that are allowed by a medium. The present study uses a structural equation model to investigate the influence of three components of technological interactivity-user control, synchronicity, and responsiveness-on web-services' perceived content performance. The results show that web-services' user control and synchronicity exhibited a positive relationship with the perceived efficiency of content generation; further, perceived efficiency boosts perceptions of content quality, which means that the user control and synchronicity of a web-service also have an indirect effect on perceived content quality. Additionally, responsiveness has a positive effect on perceived content quality. These findings are important for marketers and operators seeking to make their web-service successful.

The purpose of this study was to compare communication and mother-child interactions of reactive attachment disordered children with normal children. The subjects were 24 children and their mothers participated in this study'12 reactive attachment disordered children and mothers, 12 normal children and mothers. The mother and her child were brought into a p]lay room and the mother was instructed to play with her child as she normally would at home. The play situations were videotaped. Tapes were transcribed and transcribed data was analyzed with 13 mutually exclusive categories encompassing pragmatic functions represented in communication form the early stage of multiword speech in childhood. The tapes were analyzed with 10 behavioral mother-child interaction patterns. As the statistical method, t-test and correlation was calculated. The results of this study were as follows : 1) Reactive attachment disordered children used significantly fewer 'filler', 'information', 'requests', 'describes' and 'disscus self'. 2) Reactive attachment disordered children's mother used significantly fewer 'filler' and 'names'. 3) Reactive attachment disordered children used significantly more 'independent play', fewer 'intiates interaction', 'responsiveness' and 'answer' Reactive attachment disordered children's mother used more 'control play', 'observe' and fewer 'initiates interaction'. 4) Children's communication patterns were related lo mother·'s communication and mother-child interaction types. Children's 'filler', 'information requests', 'describes' and 'disscus self' were consistantly related to mother's 'filler' and 'names', (Children's 'filler', 'information requests', 'describes'. 'disscus self' and mother-child's intiates interaction 'responsivness' were significantly positively correlationed and 'independant play', 'control play', 'observation' were significantly negatively correlationed. The results of reveal that communication and mother-child interaction pattern of reactive attachment disordered group was different from normal group and children's communication pattern were influenced by mother's communication and interaction patterns.

This study is about the effect of interaction and flow of consumers within the company SNS on the consumers' affection. Verification took place through empirical analysis based on the theoretical background. The following is the summary of the research results generated based on the research results. First, correlation between aspect of the motivation for the use of contents and interactivity is as follows. Mutual sense of solidarity (Hypothesis 1-1), influence (Hypothesis 1-2), connectivity (Hypothesis 1-3) and reactivity (Hypothesis 1-4) exerted positive(+) on the interaction. Second, correlation between aspect of the motivation for the use of contents and flow is as follows. Mutual sense of solidarity (Hypothesis 2-1), influence (Hypothesis 2-2) and connectivity (Hypothesis 2-3) exerted positive(+) effect on immersion. Meanwhile, reactivity (Hypothesis 1-4) was not statistically significant when it comes to flow. Third, interaction between contents characteristics and interaction exerted positive(+) positive on the interactivity of entertainingness (Hypothesis 3-1) and informativity (Hypothesis 3-2). Fourth, correlation between contents characteristics and flow was examined, which demonstrated that only informativity (Hypothesis 4-2) exerted positive(+) effect on the immersion. Meanwhile, entertainingness was not statistically significant when it comes to the immersion. Lastly, correlation between interaction, flow and affection is as follows. Correlation between interactivity and flow(Hypothesis 5) was not statistically significant while interactivity(Hypothesis 6) and Flow(Hypothesis 7) exerted positive(+) effect on the affection. This study presents diverse implications and significances to the working level people who use the company SNS based on these results.

The ground state SCF IMO theory was applied to the Diels-Alder reactions of cyclopentadiene with 2-substituted acrylonitriles. The CNDO/2 MO of the separate systems, including both $\sigma$ and $\pi$ electrons, was used as starting point. The qualitative prediction of the relative reactivity was made with the calculated primary interaction energies. Here the calculated activation energies appeared to be realistic. The stereoselectivity determined by the calculated secondary interaction energies represented the endo-selectivity for all the substituents. The reason for the slightly unsymmetrical ring closure at the transition state was discussed in terms of valence inactive electron densities of the reacting atoms.

The contribution of electrostatic interactions to protein folding reaction was studied by using mutant ubiquitin with lysine to alanine mutation at residue position 29. Based on the three dimensional structure of ubiquitin, lysine 29 is located close to negatively charged glutamate 16 and aspartate 21 and considered to stabilize the native state of ubiquitin by electrostatic interactions between these residues. The equilibrium unfolding experiment showed that the native stability was decreased by about ~20% upon mutation. This observation indicates lysine 29 indeed forms electrostatic interactions with nearby residues. Folding kinetics measurements using stopped-flow device and quantitative analysis of kinetics data indicate that ubiquitin folds from unfolded state to native state via intermediate state as observed previously. This intermediate state was observed to form immediately after the initiation of folding reaction. The folding intermediate was shown to be destabilized considerably upon lysine to alanine mutation. These observations indicate that electrostatic interactions can form early stage of protein folding and hence lead the folding reaction.
