This study aims to develop and apply a metaverse-based instructional design model for the education in science and technology. It analyzed the concept and characteristics of metaverse, existing non-contact education models, and major teaching strategies systematically. Based on the prior researches, an instructional design model using metaverse is developed that presents metaverse-related teaching strategies and design principles for the before-, during-, and after-lesson phases. Then, this model was applied to a project-based learning program, conducted a perception survey on instructors and learners, and revised the metaverse instructional design model based on the results of the survey. In the Metaverse Instructional Design Model, before-lesson phase is a physical and psychological preparation stage for class participation, which includes familiarization with the Metaverse learning environment, formation of expectations for education, and self-directed pre-learning. During the lesson, to effectively deliver the lesson content, it is necessary to build confidence in the learning environment, promote learning participation, provide reference materials, perform team projects and provide feedback, digest learning content, and transfer learning content. The after-lesson phase provides strategies for ongoing interaction between learners and mentors. This study introduces a new instructional design model that utilizes metaverse and shows the potential of metaverse-based education in science and technology. It also has important implications in that it provides practical guidelines for the effective design and implementation of metaverse-based education.

Most of expert systems use the text-oriented knowledge bases. However, knowledge management using the knowledge bases is considered as a huge burden to the knowledge workers because it includes some troublesome works. It includes chasing and/or checking activities on Consistency, Redundancy, Circulation, and Refinement of the knowledge. In those cases, we consider that they could reduce the burdens by using relational database management systems-based knowledge management infrastructure and convert the knowledge into one of easy forms human can understand. Furthermore they could concentrate on the knowledge itself with the support of the systems. To meet the expectations, in this study, we have tried to develop a general-purposed knowledge conversion tool for expert systems. Especially, this study is focused on the knowledge conversions among text-oriented knowledge base, relational database knowledge base, and decision tree.

The objective of this paper is to show how team study can be advanced with the aid of a current computer technology, that is distributed Artificial Intelligence(DAI). Studying distributed problem solving by using groups of artificial agents, DAI can provide important ideas and techniques for the study of team behaviors like team decision making. To demonstrate the usefulness of DAI models as team research tools, a DAI model called 'Team-Soar' was built and a simulation experiment done with the model was introduced, Here, Team-Soar models a naval command and control team consisting of four members whose mission was to identify the threat level of aircraft. The simulation experiment was performed to examine the relationships of team decision scheme and member incompetence with team performance. Generally, the results of the Team-Soar simulation met expectations and confirmed previous findings in the literature. For example, the results support the existence of main and interaction effects of team decision scheme and member competence on team performance. Certain results of the Team-Soar simulation provide new insights about team decision making, which can be tested against human subjects or empirical data.

This study examines unique manifestations of intergenerational conflict related to the acculturation process of immigrant families. No scale that measured the acculturation aspect of intergenerational conflict exsited. Thus, a new scale was developed to investigate this unique aspect among Korean American adolescents. The study design was cross-sectional, and employed a convenience sampling method. The participants were Korean American adolescents of junior and senior high school age, 14 to18 years old. The study was conducted at eleven Korean churches and one hakwon (private out-of-school studies .institute) in Fairfax County, Virginia. Korean American adolescents expressed that the issues related to education, such as academic pressures and high expectations, caused intergenerational conflict most frequently. Unlike findings from previous studies, the participants indicated that language differences between parents and children rarely caused intergenerational conflict. Contrary to previous findings, none of the characteristics variables, such as age, gender, length of residency and language preference, were significantly correlated with this unique conflict. This study provides a rare opportunity to enhance our understanding on how Korean American adolescents interact with their immigrant parents.

The authors examined how Korean housewives manage family resources, make decisions, handle pressures, and negotiate the constraints of everyday life in a society that places unrealistic expectations upon them. The authors approached housewives by imagining them as thinking, strategizing, and problem-solving individuals, who are capable of speaking for themselves and making choices within situational and personal limits. Eleven full-time housewives were interviewed on how they experience their marriages, children, families, and society. Their narratives were then analyzed to sort out the strategies the women employed to maintain their identities. The narratives showed women's will and agency as they worked to resolve the contradictions in their daily life, and revealed individual differences within this group of women who are often seen as homogenous.

The current study uses longitudinal data, which show secondary school students' responses in a biennial data of surveys from England (n=4,326/boys=2,313;girls=2,413) and Scotland (n=3,528/boys=1,744;girls=1,784), to describe the association between availability of cigarette sales to minor, prosmoking attitudes of family members and drinking/drug use and smoking behaviours amongst adolescents. The findings provided strong evidence suggesting that availability of cigarette sales to minor, lack of familial interest on the child's smoking and other substance use were positively associated with the increased level of smoking behaviour in youth. Girls and boys also differed the likelihood of smoking and being a regular smoker. Boys were found to be more likely than girls to be smoking and to be a regular smoker. The implications of promising prevention programmes for preadolescents and areas for future research are presented

As various changes in education in general and learning environment in particular have promoted different needs and expectations for learning at both personal and social levels, the roles that schools and school teachers typically have with respect to their students are being challenged. Especially with the recent, rapid progress of the artificial intelligence(AI) field, AI could serve beyond the way in which it has been used. Based on a review of some of the related literature and the current development of AI, a view on utilizing AI to be a collaborative, complementary partner with an human mathematics teacher in the classroom in order to support both students and teachers will be discussed.
