This study examines how interactivity and usage mode of a chatbot interface affects user experience. Chatbot has rapidly been commercialized in accordance with improvements in artificial intelligence and natural language processing. However, most of the researches have focused on the technical aspect to improve the performance of chatbots, and it is necessary to study user experience on a chatbot interface. In this article, we investigated how 'interactivity' of an interface and the 'usage mode' referring to situations of a user affect the satisfaction, flow, and perceived usefulness of a chatbot for exploring user experience. As the result, first, the higher level of interactivity, the higher user experience. Second, usage mode showed interaction effect with interactivity on flow, although it didn't show the main effect. In specific, when interactivity is high in usage mode, flow was the highest rather than other conditions. Thus, for designing better chatbot interfaces, it should be considered to increase the degree of interactivity, and for users to achieve a goal easily through various functions with high interactivity.

A major limitation of available component-based platforms Is that they do not provide suitable means for describing and reasoning on the concurrent behaviour of interacting component-based system. Indeed while these platforms provide convenient ways to describe the typed signatures of components, e.g. like CORBA's IDL, they offer a quite low-level support to describe the concurrent behaviour of component. The ability to describe and verify the concurrent behaviour of interacting components is key aspect In the development of large component-based software system. This study propose a component interface specification using process algebra and configuration's role which allows one to prove correctness of software architecture generated at design level as well as to define compatibility relations by our evolution rule and $\pi$-graph. Also, we shown on an appropriateness of a specification techniques and definitions proposed in this paper by case-study.

This study aims to look for care quality factors reduce the daily stress of young children placed in care centers for long hours. Therefore, the research questions look into how the hours and care quality factors in child care centers affect young children's daily stress, and whether the care quality factor moderates the impact of the hours children spent in centers. The subjects in this study were 380 children from 3 to 5 years old from 10 child care centers. The Korean Preschool Daily Stress Scale(KPDSS) for children's daily stress and Early Childhood Environmental Rating Scale-Revised(ECERS-R) for quality of each classroom of centers were implemented. The main findings were summarized as following: (1) The more hours he/she spent in the center, the more stress he/she had. Children who spent 9 hours or more had more stress than children with 7 hours or less. (2) Among the 7 quality factors including space and furnishings, personal care routines, language reasoning, activities, interaction, program structure, parents staff, the interaction level between a teacher and a child and the level of parents and staff had the most impact on children's daily stress. (3) The qualitative factors of child care, language reasoning level, interaction level, parental support, and level of teachers reduced children's daily stress which was affected by the hours they spent in centers. Thus in order to reduce the daily stress of children who attend more than 9 hours a day, it is crucial to promote language reasoning activities and interaction between teachers and children and to improve parental support and teachers' professionalism.

In most leading companies, new product development is one of the most important corporate activities which affects the very existence of them. Therefore, CFT(cross-functional team) is frequently used to utilize knowledge and experiences of its members from various teams. To ensure the successful operation of CFT, various structural assistances, such as committee and Task Force Team, are made which will coordinate smooth interactions among members. Many researches show that the increase of interaction among team members affects the performance. This research is exploratory research intend to show the effects of relational characteristics such as group efficacy and participation on the perceived performance of new product development. This research examines the performance mechanism that lies in between CFT and its members by expanding the understandings on the relationship between interaction and performance in new product development CFT. Results show that the level of interaction affect group efficacy. and group efficacy affect participation. Finally, participation affect perceived performance. However. it shows that the level of interaction and group efficacy do not have direct effect on perceived performance.

As various genome projects have produced enormous amount of biosequence data, functional sequence analysis in terms of tile nucleic acid and protein becomes very significant. In functional genomics and proteomics, the functional analysis of each individual gene and protein remains a big challenge. Contrary to traditional studies, which regard proteins as not components of a whole protein interaction network but individual entities, recent studies have focused on examining functions and roles of each individual gene and protein in view of a whole life system. In this regard, it has been recognized as an appropriate method to analyze protein function on the basis of synthetic information of its interaction and domain modularity. In this context, this paper introduces the PIVS (Protein-protein interaction Inference & Visualization System), which predicts the interaction relationship of input proteins by taking advantage of information on homology degree, domain modules which input sequences contain, and protein interaction relationship. The information on domain modules can increase the accuracy of the function and interaction relationship analysis in terms of the specificity and sensitivity.

The purpose of this study was to determine if teachers' perception of professionalism, teaching intentions, and the quality of teacher-child interactions differed by teachers' education and career and how those variables were associated with one another. It was conducted in 50 teachers who were in charge of two- to five-year-olds at 22 national/public, private, and employer-supported childcare centers in Seoul and Gyeonggi Province. Arnett's (1989) Caregiver Interaction Scale (CIS) translated by Choi and Shin (2015) was used to measure the quality of teacher-child interactions, and the Current Status and Self-Desire for Professional Competence scale developed by Wang (2005) and translated and revised by Jeong (2016) was used to measure a teacher's perception of professionalism. The Teaching Intention Scale (TIS) developed by Wilcox-Herzog and Ward (2004) and translated and revised by the researcher was used to measure teaching intentions. The researcher and the research assistant personally visited the centers to observe the teachers for the quality of teacher-child interactions and a questionnaire for teachers was used to determine a teacher's perception of professionalism and teaching intentions. For data analysis, t-test and Pearson's product-moment correlation analysis were performed on the basis of the questions. The results of this study can be summarized as follows: First, the quality of teacher-child interactions differed insignificantly by education or career. Second, teacher's perception of professionalism differed significantly by teachers' career but differed insignificantly by education: the longer career, the better perception of professionalism. Third, teaching intentions differed insignificantly by education or career. Fourth, teachers with better perception of professionalism showed higher quality of teacher-child interaction. Fifth, The higher level of teaching intentions teachers showed the more sensitive interactions they made with children.

Tools and methods for interacting with the virtual environment are essential in order for a student to perform the virtual reality education contents. However, since the developed controller has generally been constructed for adults, it is necessary to study interaction tools considering the purpose of education and the level of students. Therefore, this study analyzed elementary and middle school students' perceptions of HMD and interactive tools, which are currently widely used as an initial research for developing interactive tools. Results show that students' perceptions has increased in post-questionnaire compared to pre-questionnaire, indicating that the universal controller can be used in the education. Implications for the development of interaction tools are discussed based on interviews with students.
