Recently, as per a representative education method to develop core capabilities (such as critical thinking, communication, collaboration, and creativity) problem based learning (PBL) has been widely adopted in universities. Two important features of PBL are 'collaboration between team members' and 'participation based self-directed learning'. These two features should be satisfied in online education, although it is difficult due to the limitation on space and time in the COVID-19 pandemic. This paper presents a new design of PBL class in Metaverse, based on improving the online PBL class operated in the previous semesters in the H university. In the proposed PBL class, students are able to display materials (e.g., image, pdf, video files) in 3D virtual space, that are related to problem solving. The 3D virtual space is called gallery in this paper. The concept of gallery allows for active participation of students. In addition, the gallery can be used as a tool for collaborative meeting or for final presentation. If possible, the new design of PBL class will be applied and its effectiveness will be analyzed.

This study investigates the impact of transactional leadership on job performance(team performance) and job satisfaction, with a focus on the mediating effect of job engagement. This study highlights the significance of contingent rewards and management by exception, components of transactional leadership, in motivating organizational members towards achievement and maintaining high performance levels. Through analysis, this research aims to demonstrate how transactional leadership affects employees' job engagement, subsequently influencing job performance and satisfaction. By understanding the role of job engagement as a mediator, organizations can adjust leadership styles and enhance job engagement, ultimately improving organizational performance and employee satisfaction. The findings suggest a composite approach to leadership, integrating both transactional and transformational elements, is more effective in fostering high job performance and satisfaction among employees. This study provides insights into developing strategies to boost job engagement and optimize leadership practices for better organizational outcomes.

Electroencephalography (EEG) is a test that diagnoses epilepsy and measures brain function. During EEG, the space between the electrode and the skin is filled with a conductive paste to reduce the impedance between the electrode and the scalp, which helps measure the EEG signals. This study compared the artifacts of the two representative conductive pastes (Ten20 and Elefix). The artifacts, noise, and satisfaction were surveyed after using the two conductive pastes. The two conductive pastes had similar artifacts and noise, but the survey results showed that the Elefix conductive paste had better satisfaction and adhesion. This result may be explained by the imprinting effect according to the experience of using the Elefix conductive paste first in the EEG class. Hence, further research is needed.

The purpose of this study is to develop a systematic and effective PBL-based robot education program for improving creativity, and to analyze its effect on improving creativity of students in a science high school. The programs for 22 classes, designed to be used in a science high school, were developed and implemented. 8 teams got the abilities to independently build their own robots throughout all the process. The resultant improvement in creativity was analyzed in terms of gender and academic achievements. In the TTCT test, there was a significant improvement in creativity, especially the greatest in a subcategory 'originality.' While there was no significant difference in creativity by gender, there was a little difference in creativity by academic achievement. Especially the lowest group (Ha) showed the greatest improvement in creativity. This robot education program is expected to be used as an introductory one for the college of engineering.

The 21st century is called as the "Age of knowledge flood", and thus the importance of the ability which can use knowledge creatively is more emphasized. Also, not only individual problem solving but also solving problems through effective communication skills with group members are needed, and therefore, it is requested to train potential gifted learner working together with others to practice cooperation and eventually grown up as a competitive human resource to adapt successfully in future environment. In this paper, to show the effectiveness of cooperative learning in gifted learners, members for cooperative learning group has been selected using whole brain theory from the 42 gifted middle school students who participated in summer gifted learner vacation program. From the analysis of the learners' learning motivation and frequency of interactions whole brain based cooperative learning is effective for enhancing both learning motivation and interactions. Therefore, the whole brain based cooperative learning is an effective pedagogy for enhancing the motivation as well as facilitating interactions within gifted learners.

Modern society has a tendency to raise fewer children. As a result, parents became more interested in their children's creative ways of thinking and began to look for new ways of teaching. The child care support center expects a positive effect by lending various toys and books to improve the physical, emotional and social characteristics of children and to help reduce household burden on parents. In this paper, we design and implement a rental return system to effectively utilize a toy library operated by the child care support center. The proposed system makes it easy for any user to search for items in any branch operated by the Child Care Support Center and to manage loan return records. The administrator can manage data such as loans, returns, and past due from the rental return processing system, and effectively operate the child care support center through statistics of data generated. Children are expected to be given a variety of entertainment cultures and cultural benefits to their families to ease the burden of parenting.

This study analyzed the positive effect of perceived over-qualification on creative behavior, moving away from the perspective of previous studies that mainly focus on the negative effects of perceived over-qualification. A survey of 282 employees in the financial industry in China was conducted and the structural equation model analysis was used. As a result of the analysis, perceived over-qualification has a positive effect on employees' creative behavior, the fact that perceived over-qualification has a positive effect on creative behavior has enriched research on the effect of perceived over-qualification th some extent. In addition, theoretical and practical implications were provided by demonstrating the relationship between creative behavior, emotional exhaustion, job crafting, and perceived organizational support. It was measured in the terms of subjective over-qualification, Discussions on over-qualified recognition remain at the individual level of employees, and future studies need to study the collective phenomenon of over-qualified recognition at the team level or organization level.

With the steady increase in the annual number of earthquakes in South Korea, the need to apply seismic reinforcement on public facilities has recently increased. To reinforce seismic capacity, spaced full-column-height steel bars are attached to column faces. In this study, nonlinear finite element analysis was conducted to analyze the effect of external reinforcement steel bars on the seismic capacity of RC columns with a square or rectangular cross-section. For verification, the analysis results were compared with test results. Results showed that the finite element analysis reasonably predicted the actual structural behavior of RC columns with steel bars. In addition, both the analysis and the test results showed that the failure mode was converted from brittle failure to ductile fracture, owing to the external reinforcement steel bars. Both loading capacity and ductility were increased as well. Therefore, the external reinforcement steel bar can effectively enhance the seismic capacity of existing RC columns. This study is expected to contribute to relevant research areas such as the development of design methods.
