This qualitative study investigated different interaction patterns in an online discussion. The data was collected from asynchronous discussion occurred in a graduate course. The data analysis methods include inductive analysis and mapping strategy. The results of the study suggest three layers of interaction: response sequences, interaction amongst participants, and concept map of messages. The visualization of response sequences enabled the researcher to discover complex and dynamic interaction patterns amongst participants. The many-to-many communication feature of online discussion does not always enable direct one-on-one interaction between two participants. Rather, one message contributed to multiple threads in the stream of conversation. In terms of interaction amongst participants, the interaction amongst participants, as indicated in the data, the messages also bind each participant and consequently a group(s) of participants together. It appears that the contribution of one message may not only enable a response to one participant, but also connect many participants to each other. The concept map of messages proposes that response sequences and interaction amongst participants can also be viewed between concepts within messages in the discussion. On the surface, the messages posted by individuals are linked by the system in a linear fashion as they are posted. However, the interaction extends to collaborative conversation amongst participants. Ultimately, a conceptual network of interrelated ideas including multiple perspectives is built in asynchronous discussion.

본 연구는 유아의 문제행동에 대한 부모와 교사의 인식차이 연구로 유아의 문제행동에 대해 부모와 교사 간 인식차이 분석 결과 유아의 모든 문제행동 유형에 대하여 부모와 교사 간의 인식 차이가 뚜렷한 것으로 나타나고 특히 부모보다 교사들이 문제행동에 대해서 비교적 문제가 있다고 인식하고 있는 것으로 나타났다. 그리고 유아 지도전략에 대한 부모와 교사의 인식 차이에 있어서도 유아의 지도전략에 대해 부모와 교사의 인식에 있어, 반응적 상호작용과 교육기관에서의 예방실제가 선호되는 것으로 나타나 이는 부모보다 교사가 통계적으로 유의미하게 높은 것으로 나타난 반면 사회정서 전략에 있어서는 유의미한 차이가 없는 것으로 나타났다. 이 같은 결과는 원래 유아들의 다양한 문제행동을 통제관리 해야 하는 교사의 입장에서 편중된 지도전략보다 사회 정서적으로 인식되고 있는 공통적 지도전략에 바탕을 두되 교사 유아 간 발생되는 문제행동 유형과 대상유아에 따라 반응적 상호작용하는 지도전략이 선호되고 특히 돌출문제 행동이 많이 발생하는 유아의 행동 특성을 고려할 때 돌출문제 유아의 행동억제와 예방에 중점을 둔 반응적 상호작용 전략과 예방실제 지도전략이 선호되고 있음을 시사한 것으로 평가 할 수 있다.

This study explores factors to facilitate web-based collaborative learning and the effect of learning, based on the PBL(Problem Based Learning) from the constructivist approach in e-learning. A research model, using the key variables such as situations, interactions, and systems, was developed. In order to test this proposed model, experimental design and post-survey was conducted to the learners who took on-line and off-line course with team project. In the research model, situation category was divided into instructor's support, unstructured problem, and self-directed learning. Interaction category was divided into three factors; 'interaction between learners', 'interaction between learner and instructor', and 'interaction between learner and technology'. System category was divided into.monitoring and incentives. As a result, it was found that collaborative learning can be improved by situations, interactions, and systems, and the effectiveness of learning can be improved by situations and interactions in PBL.

The aim of the current study was to suggest priorities needed to be considered by university instructors when designing online learning. Based on three types of interactions (learner-content, learner-instructor, and learner-learner interactions) for effective online learning (Moore, 1989), draft questionnaires representing each type of interaction were written. After examining content validity by two Ph.D. experts, the survey was constructed with an Importance-Performance Analysis (IPA) form. Data of 133 university instructors were collected online. Results showed that support for designing learner-learner interaction was the priority for improving online learning. In terms of learner-instructor interaction, instructors needed to provide social-emotional support to learners so that learners could have a sense of belonging. For learner-instructor interaction, supporting instructors to monitor the level of understanding was the most highly demanding strategy for online learning. Limitations and suggestions for further studies were discussed.

While the literature is replete with arguments that corporate strategy, structure, and culture independently matter in explaining the growth and survival of firms, little theoretical and empirical attention has been devoted to understanding how the three organizational factors develop over time in interaction. Through in-depth case study, we examine the POSCO's historical development with respect to the strategy-structure-culture interface. Furthermore, by looking at the POSCO's longitudinal financial data we gain insight into whether the aligned evolution of strategy, structure, and culture is associated with performance.

With the increasing use of the Internet improved Internet technologies as well as web-based applications, the uses of e-Learning have also increased the effectiveness of e-Learning has become one of the most practically and theoretically important issues in both Educational Engineering and Information Systems. This study suggests a research model, based on an e-Learning success model, the relationship of the e-leaner's self-regulated learning strategy and the quality perception of the e-Learning environment. This research model focuses on the learning environment and on self regulated learning strategy. The former consists of LMS, learning contents and interaction that are provided by e-Learning and the latter refers to the learners' self-regulated learning strategy. We will show the validity of the model empirically. As result, most of the hypotheses except for H6 suggested in this model were accepted.

This study aims to explore the new paradigm of regional development strategy with the theory of Resilience. Resilience can be defined in terms of a set of interacted capacities to absorb and adapted to different kinds of shocks and disturbance at the regional level. This study focuses particularly on the interaction of component of resilience with the context of regional development strategy. As a result of the Systems thinking approach about dynamic interactions between resilience components and regional problems, this study find that there are many feedback structures which is need for a better understanding of the complex regional resilient development system. This study suggests that the Archytypes of resilience-focused strategy of regional development, which could help achieve an evolution for regional community and people to adapt and bounce back from crisis.

This study was designed to investigate the relation between mother's interaction strategies and self-regulation of young children from a Vygotskian perspective. The hypotheses of this study were: 1) The self-regulation of young children will improve with increase in age, 2) the use of mothers' interaction strategies will increase as child's age decreases, 3) mothers' directiveness in the mother-child interaction depends on the age of child and socio-economic level, and 4) mothers' directiveness in the mother-child interaction will have negative relationship with child's self-regulation. The subjects of this study were 60 mother-child dyads with three different age-of-child groups (3-, 4-, and 5-year-olds). They were further divided into higher and lower socio-economic groups. A puzzle task was used for the measurement of self-regulation. The task consisted of two identical puzzles with one used as the model. The collected data were analyzed by ${\chi}^2$, one-way and two-way analysis of variance, and Pearson's r. Self-regulation of the young children improved with increase in age (P < .05). The use of mothers' interaction strategy decreased as the children's age increased (P < .05). Mothers' directiveness in the mother-child interaction was influenced by the age of child (P < .01) and by socioeconomic level (P < .05). There was a negative correlation (r=-.848) between the mothers' directiveness in the mother-child interaction and the child's self-regulation (P < .001).
