The purpose of this study was to investigate interaction patterns and characteristics of small group discussions during elementary school science classes. Four heterogeneous groups were formed according to preferences and non-preferences, consisting of male and female students. Verbal interactions during small group discussions were audio and videotaped, transcribed and analyzed. The interaction frequency of each group was compared in terms of their cognitive and affective aspects. The results in terms of the cognitive aspect showed that there were no significant differences in the frequency of interaction between preference and non-preference groups' verbal behaviors. However, the quality of interaction was superior and the number of high level types of interaction were more frequent in the preference group. From the affective perspective, both groups of students exhibited a positive attitude in the preference group and a negative attitude in the non-preference group. The differences of interaction between the male and female student's groups were that in the case of the female group, the frequency and the quality of interaction was higher. Moreover, in contrast to male students, female students revealed satisfaction and favorable attitudes in their non-preference group because they felt more a acceptable atmosphere and attitude in that group. These results suggest that the interactions of the preference group are more interactive and elaborate in nature than those of the non-preference group.

Objective: The aim of this study was to evaluate the effect of ageing and feeding strategies on the calpain protease system and meat quality traits in Braford steers. Methods: Thirty Braford steers were employed; 15 animals were supplemented with corn silage during finishing and 15 were kept only on pasture. Meat quality traits and calpain system protein activity were evaluated in longissimus thoracis et lumborum (LTL) steaks aged for 2, 7, 14, and 21 days. Results: Aged meat showed higher pH and calcium content, while Warner Bratzler shear force (WBSF) decreased to day 21. No interaction between ageing and diet was seen for quality traits. Steers finished with corn silage showed higher values of water holding capacity, WBSF and free calcium, and lower values of pH and cooking loss. Calpain and calpastatin activities decreased with ageing. Finishing steers on pasture produced higher values of calpains and lower values of calpastatin activities. The higher values of calpain 1 activity were observed in muscles aged 2 days from pasture finished animals, and the lower activity of the inhibitor in the 21 days aged samples of the same group. Conclusion: These results suggest a diet by ageing interaction in calpains and calpastatin and this interaction impact in Warner Bratzler Shear Force in Braford LTL muscle.

The purpose of this study was to investigate the characteristics of 2nd grade students' interaction in the classification activities of LTTS. For the purposes of this study, three heterogeneous groups, chosen by cognitive level, were selected. The students' interactions were audio/video taped and classified as either cognitive or affective interaction. The results of this study are as follows. In the cognitive interactions, the frequency and quality of the functions of 'questions' and 'making suggestions' were higher than those of 'Responses' and 'Receiving opinions'. In the affective interactions, the frequency of 'induction' and 'dissatisfaction' was higher than that of the other types. The frequency and quality of interactions of students in both the early and mid concrete stage were higher than those of students in the transitional stage. Qualitatively higher-level interactions such as 'making suggestions' and positive interactions such as 'induction' to induce students who were passive in activities were made by the students at higher cognitive levels. However, the low-level of interaction in suggesting their opinion to the constituent's suggestion and 'dissatisfaction' with student in transition period who were passive in activity influenced group working negatively.

Various interaction techniques have been studied for providing the feeling of touch and improve immersion in augmented reality (AR) environments. Tangible AR interaction exploiting two types (product-type and pointer-type) of simple objects has earned great interest for cost-effective design evaluation of digital handheld products. When the sizes of markers attached to the objects are kept big to obtain better marker recognition, the pointer-type object frequently and significantly occludes the product-type object, which deteriorates natural visualization and level of immersion in an AR environment. In this paper, in order to overcome such problems, we propose tangible AR interaction using fingertip touch combined with small-sized markers. The proposed approach facilitates the use of convex polygons to recover the boundaries of AR markers which are partially occluded. It also properly enlarges the pattern area of each AR marker to reduce the sizes of AR markers without sacrificing the quality of marker detection. We empirically verified the quality of the proposed approach, and applied it in the process of design evaluation of digital products. From experimental results, we found that the approach is comparably accurate enough to be applied to the design evaluation process and tangible enough to provide a pseudo feeling of manipulating virtual products with human hands.

In China, E-commerce live broadcast has emerged as the most popular and innovative online shopping form for today's consumers, and its "real-time interactive" feature can compensate for the communication delays of general online shopping. Based on the author's previous research it has been demonstrated that, in the E-commerce live broadcast environment, Internet Word of Mouth (IWOM) has become an important reference for consumers when making purchases. In this paper, we reconstructed the "IWOM-Purchase Intentions" model and use interaction (Auchor-Audience and Audience-Audience) as a mediating variable to empirically investigate the impact of IWOM on purchase intentions in E-commerce live broadcast. The data were collected through a questionnaire survey of individuals who had experience in E-commerce live broadcast and 250 valid data were obtained and analyzed by SPSS21.0. The results show that: the interaction (Auchor-Audience) acts as a mediator between IWOM (strength of relationship; word-of-mouth quality and word-of-mouth timeliness) and purchase intention; And the interaction (Audience-Audience) acts as a mediator between word-of-mouth timeliness on purchase intention, but has no significant mediation on the impact on the strength of relationship and word-of-mouth quality to purchase intention. On this basis, recommendations are made for the implementation of IWOM marketing strategies for E-commerce live broadcast platforms and anchors.

The threat of COVID-19 pandemic put many universities in Korea to develop and implement various types of non-face-to-face on-line classes, such as on-line real time class and on-line recorded video class. Online education has been recognized as one of the effective educational methods because of its ubiquitous and flexible educational environments. Even though COVID-19 led to many problems such as faculty's burden and stress during the early stage of COVID-19, both students and faculties have gradually become familiar with on-line environment. As students have got accustomed to the online environment, on-line recorded lectures are shown to be more preferred rather than on-line real time class. Researches regarding the learner's satisfaction of on-line classes during the COVID-19 indicate that systematic and good quality contents and interaction by instructor are important factors. This study, therefore, investigate the learner's satisfaction of online classes in Liberal Arts course using recorded video contents in terms of contents and interaction. The results of empirical analysis reveal that systematic and good quality contents are likely to predict learner's satisfaction and interaction plays a great role in providing those contents. These findings provide insights that preparing systematic contents and interaction are key to enhancing learner's satisfaction of on-line classes in Liberal Arts course.

Objective: This study explored the relationship between early childhood teachers' teaching efficacy, teacher-child interaction, and preschoolers' school readiness. Methods: The data were drawn from the seventh wave of the Panel Study on Korean Children. The subjects of this study were 1,150 preschoolers and their teachers. Early childhood teachers reported their teaching efficacy, their interaction with preschoolers, and preschoolers' school readiness. Data were analyzed using structural equation modeling. Results: First, early childhood teachers' teaching efficacy did not have a direct effect on preschoolers' school readiness. Second, early childhood teachers' teaching efficacy had an indirect effect on preschoolers' school readiness through teacher-child interaction. In other words, teachers with a high level of teaching efficacy had high-quality interactions with preschoolers, which led to preschoolers showing a high level of school readiness. Conclusion/Implications: The results of this study highlight the importance of teachers' high teaching efficacy and high-quality interactions between teachers and preschoolers to improve preschoolers' school readiness. In addition, this study contributes to a better understanding of the mechanism by which teachers' teaching efficacy influences preschoolers' school readiness.

Information systems development entails planning, analysis, design and construction phases. The analysis phase identifying user requirements is the most important of these phases. Since unidentified defects in the early phase causes increased work and costs as development proceeds, the quality of analysis results affects the quality of the resultant system. Major tasks in the analysis phase are data modeling and process modeling. Research on building a knowledge-based system for data modeling have been conducted much, however, not sufficiently for process modeling. As a system environment with high user interaction increases, research on process modeling methods and knowledge- based systems considering such environment are required. In this research, a process modeling framework for information systems with high user interaction is suggested and a knowledge-based system for supporting the suggested framework is implemented. A proposed model consists of the following tasks: event analysis, process analysis, and event/process interaction analysis. Event analysis identifies business events and their responses. Process analysis break down the processes of an enterprise into progressively increasing details. Decomposition begins at the function level and ends when the elementary process level is reached. Event/process interaction analysis verifies the results of process analysis and event analysis. A knowledge-based system for supporting a proposed process modeling framework is implemented in a web-based environment.
