This study examined the characteristics of verbal interactions presented in TS activities with different tasks' openness levels by the cognitive levels of students through the implementation of TS program to 14 fifth graders in gifted class. Results of this study revealed that the open-type TS activities showed higher percentages of verbal interactions than the guiding-type TS activities showed and that the higher the open level of tasks was, the more high-level verbal interactions occurred. These results were showed in almost all subcomponents of verbal interactions. The results according to the students' cognitive levels showed that the higher the cognitive level of students was, higher frequency of interactions, high-level verbal interactions and a variety of verbal interactions occurred. The influence of both cognitive level of students and the task's openness on verbal interactions among students seemed to be interactive, however. In guiding-type activities, the percentage of high-level verbal interactions was not high although the cognitive level of students was high. And students in low level of cognition showed far lower frequency of interactions and their percentage of high-level verbal interactions was low even though the openness of the tasks was high. The results of this study meant that although open-type activities drew higher level verbal interactions by stimulating students' thought, the effects would be limited owing to their low cognitive level. Based on these findings, an implication was suggested that it is important to design instructional strategies and adjust openness level of TS activities to students' cognitive level so as to stimulate the thinking of students in lower cognitive level and to highten their engagement in activities.

Satisfactory e-learning experience of working part-time adult students is a truly dynamic and multidimensional process that reflects learning needs and abilities. Special attention is given to understanding the role of student-to-faculty interaction, student-to-student interaction, e-learning content and course structure, flow, periodic off-line class meetings and synchronous Q&A sessions. Survey questions were developed and distributed to adult graduate students. Some of them were asked to complete the questions with the most interesting subjects or classes in their mind, and others with the most difficult subjects in their mind. The structural model for each group was tested. The values of path coefficients corresponding to the group with the difficult subjects turn out to be higher for the following paths; a) interaction among professors and students and satisfaction, b) contents quality and flow, c) Q&A and interaction among professors and students, d) Q&A and interaction among students. For the other paths such as interaction among students and satisfaction, contents structure and flow, the coefficient values corresponding to the group with the interesting subjects are higher. Some implications for e-learning design were provided as well.

IT has been receiving increasing attention for cloud computing services. However, despite a lot of attention, there are limitations of existing research on cloud computing services. There are researches respectively about the benefits and costs that would occur if you choose a cloud computing services. However, in real life, consumers should be considered about the benefits and costs at the same time if they choose and use a cloud computing service. Therefore, this study examines the interaction effect of benefits and costs on cloud computing service. The findings demonstrate that three independent variables(usefulness, social influence, and innovativeness) positively(+) affect the perceived value. However, showed the benefits and costs of interaction effects analysis, usefulness and innovation on the cost influence the perceived value in statistics. The interaction of the usefulness & cost shows negative(-) effect and the interaction of the innovativeness & cost has positve(+) effect on the perceived value. In conclusion, this study provide that consumers need to consider costs with benefits when they use a cloud computing service.

The purpose of this study was to investigate the effects of science inquiry experiments emphasizing social interaction on the development of process skills of the students. The social interactions by cognitive level of the students were also analyzed. For this study, 197 8th grade students were sampled. They were divided into an experimental group and a control group. During four-month period, the experimental group received science inquiry experiments treatment emphasizing social interactions while the control group received traditional treatment. Not only science inquiry ability pretest-posttest, but also multiple data collection method such as a questionnaire, class observation, and audio/video recording were used in collecting the data. According to the results of this study, it was found that the mean score of the experimental group was significantly higher than that of the control group at 0.05 level. It was also found that the students of high cognitive level led the peers and participated in the class discussion actively with the teacher while the students of low cognitive level followed the students of high cognitive level and showed inactive interaction with the teacher. Analysis of the students' perceptions on inquiry experiments showed that students participated in discussion actively in the class as these experiments gave an opportunity for them to discuss and were able to solve the problems with peers' help through discussion.

디지털 기술의 발전은 다양한 정보들과의 새로운 상호작용들을 창출하고 있고, 여기에서 인터페이스는 상호작용을 가능하게 하는 구체적인 장으로서, 우리가 정보들과 갖는 상호작용 방식을 규정한다. 그런데, 확장현실이나 유비쿼터스 컴퓨팅과 같은 새로운 기술적인 흐름들은 우리의 물리적 공간에 디지털 정보라는 무형의 층위를 더함으로써, 현재의 손과 눈의 작용을 중심기반으로 하는 상호작용 방식들로부터 발전된 형태의 상호작용이 필요하게 될 것임을 시사하고 있다. 이에 본 논문에서는 물리적 공간 안에서의 우리 자신을 형성하고, 세계를 인지하는 근간이 되는 신체에 초점을 맞추어, 신체가 새로운 정보 환경 속에서 정보의 인지 메커니즘과 상호작용의 주체로서 어떻게 기능할 수 있을 것인지를 메를로-퐁티의 현상학과 구현인지 이론을 바탕으로 탐구하고, 그 실질적인 예와 가능성들을 인터랙티브 아트 작품들에서 찾아본다.

애드혹 유비쿼터스 컴퓨팅 환경에서 상호작용 미들웨어는 컨텍스트의 변화에 따라 애플리케이션간의 상호작용을 재구성할 수 있도록 지원해야 한다. 또한 미들웨어는 컨텍스트 인지 상호작용을 지원하는데 있어 컨텍스트 종류나 애플리케이션들 혹은 환경의 다양성에 따라 컨텍스트 변화에 대한 적응성을 동적으로 변화시킬 수 있도록 기능을 제공해야 한다. 하지만 기존 연구들은 컨텍스트 변화에 대한 적응성을 변화시키는 이러한 요소들에 대해 고려하지 않으며 그로 인해 컨텍스트 변화에 대한 적응 정도를 정적으로 설정함으로써 컨텍스트 인지 상호작용을 지원하는데 있어 경우에 따라 오버헤드가 발생하거나 컨텍스트 변화에 빠르게 대응하지 못한다. 따라서 본 연구는 애드혹 유비쿼터스 컴퓨팅 환경에서 동작하는 Publish/Subscribe 기반의 상호작용 미들웨어에서 이벤트 중계의 정확성과 컨텍스트 변화 적응성간의 관계를 기반으로 다양한 컨텍스트 종류나 사용자, 환경에 따라 이벤트 중계의 정확도를 동적으로 조절하는 기법을 제안한다. 그리고 이를 기반으로 이벤트 중계 정보를 동적으로 재구성하여 컨텍스트에 맞춰 효율적으로 컨텍스트 인지 상호작용을 구성할 수 있는 기법을 제안한다. 비교 분석 결과 기존 연구에 비해 컨텍스트 변화에 대한 적응성에서 더 나은 결과를 보여주었다.

This study was attempted to verify the mediating effect of perceived interaction in the relationship between learning flow and problem-solving confidence of nursing students who experienced team-based nursing practice learning. The subjects of this study were 148 senior nursing students who experienced team-based nursing practice learning classes. Data were collected using a structured questionnaire. For data analysis, descriptive statistics, Pearson correlation analysis, hierarchical multiple regression analysis, and Sobel test were conducted. The results of the study showed that nursing students' learning flow was 3.58±0.56 points, perceived interaction was 4.06±0.56 points, and problem-solving confidence was 3.67±0.53 points on average. Learning flow of nursing students showed a positive correlation with perceived interaction(r=0.63, p<.001) and problem-solving confidence(r=0.74, p<.001). Perceived interaction showed a partial mediating effect in the relationship between learning flow and problem-solving confidence(z=5.31, p<.001). It may be necessary to develop programs to improve nursing students' learning flow, perceived interaction, and problem-solving confidence, and to improve their clinical practice ability to solve nursing problems in various nursing settings.

This paper examines an augmented technology acceptance model, which includes perceived interaction as a mediator in the relationships between the technology acceptance model (perceived ease of use, perceived usefulness) and student satisfaction in online classes, and its impact on student satisfaction. Data has been collected from 842 undergraduate students in online universities. The data is analyzed by using factor analysis and structural equation modeling techniques. The results demonstrate that perceived ease of use, perceived usefulness, and perceived interaction serve as predictors for student satisfaction in online classes. Perceived usefulness has a positive relationship with perceived interaction while perceived ease of use has no effect on interaction.

This paper analyzed class satisfaction and perceived learning achievement to the interaction type on e-learning in university. To achieve the study's objective, one course with and another course without learner-instructor interactions were selected. A total of184 student-respondents completed the questionnaire. Accordingly, more learner-content and learning-system interactions were noted in the course with learner-instructor interactions. Moreover, a correlation was observed between interaction, class satisfaction, and learning achievement. Learner-instructor interactions indicated the highest effect on both educational satisfaction and perceived learning achievement, followed by learner-system interactions on class satisfaction, and by learner-instructor interactions on learning achievement. Recommendations were then formulated based on the foregoing findings. First, workshops or training focusing on content development and on how to present the course should be provided to the instructors. Second, learner-instructor interactions should be activated in the course through various means. In this study, although learner-learner interactions was not given focus, future studied should delve into how learner-learner interaction should be activated and considered.
