  • After COVID-19, organizations have widely adopted platforms such as zoom or developed their proprietary online real-time systems for remote work, with recent forays into incorporating the metaverse for meetings and publicity. While ongoing studies investigate the impact of avatar customization, expansive virtual environments, and past virtual experiences on participant satisfaction within virtual reality or metaverse settings, the utilization of the metaverse as a dedicated workspace is still an evolving area. There exists a notable gap in research concerning the factors influencing the performance of the metaverse as a workspace, particularly in non-immersive work-type metaverses. Unlike studies focusing on immersive virtual reality or metaverses emphasizing immersion and presence, the majority of contemporary work-oriented metaverses tend to be non-immersive. As such, understanding the factors that contribute to the success of these existing non-immersive metaverses becomes crucial. Hence, this paper aims to empirically analyze the factors impacting personal outcomes in the non-immersive metaverse workspace and derive implications from the results. To achieve this, the study adopts the Embodied Social Presence (ESP) model as a theoretical foundation, modifying and proposing a research model tailored to the non-immersive metaverse workspace. The findings validate that the impact of presence on task engagement and task involvement exhibits a moderating effect based on the metaverse platform used. Following interviews with participants engaged in non-immersive metaverse workplaces (specifically Gather Town and Ifland), a survey was conducted to gather comprehensive insights.

  • Korean local governments operates the participatory budgeting system autonomously. This study is to classify these entities into clusters. Among the diverse machine learning methodologies(Neural Network, Rule Induction(CN2), KNN, Decision Tree, Random Forest, Gradient Boosting, SVM, Naïve Bayes), the Support Vector Machine technique emerged as the most efficacious in the analysis of 2022 Korean municipalities data. The first cluster C1 is characterized by minimal committee activity but a substantial allocation of participatory budgeting; another cluster C3 comprises cities that exhibit a passive stance. The majority of cities falls into the final cluster C2 which is noted for its proactive engagement in. Overall, most Korean local government operates the participatory busgeting system in good shape. Only a small number of cities is less active in this system. We anticipate that analyzing time-series data from the past decade in follow-up studies will further enhance the reliability of classifying local government types regarding participatory budgeting.

  • This study conducted surveys and in-depth interviews to explore the perception of sports psychology counseling among athletes. The participants included a total of 8 individuals: 307 athletes surveyed, 4 athletes who had received counseling, and 4 who had not. The survey investigated athletes' perceptions and management of psychological training, the perceived necessity of seeking advice for everyday concerns, willingness to use and perceived need for sports psychology counseling, prior experiences, and pre-engagement considerations. According to the survey results, 69.1% of athletes recognized the importance of mental training, but only 33.2% actually underwent psychological training. Furthermore, while 67.8% expressed a desire to receive education on psychological training from professionals, only 19.9% reported having searched for related information. When asked about their willingness to pay for sports psychology counseling services, 55.7% expressed willingness. Reasons for wanting to receive counseling, reasons for not wanting to receive counseling, and preferences or considerations for counseling sessions were listed as well. In the in-depth interviews, participants were classified into those who had received counseling and those who had not, delving deeply into motivations for seeking counseling or reasons for not doing so, perceptions during counseling sessions, considerations, preferred types of counselors, and program preferences. Based on this research, discussions and recommendations were provided with the perspective of utilizing sports psychology counseling as foundational data for providing high-quality services to users.

  • Although the relationship between social networking sites (SNS) use and performance has been widely studied, most of these studies have focused on comparing the SNS users' overall performance with that of non-SNS users instead of examining how using SNS midway of a task affects one's task performance. To address this research gap, an experiment was conducted to examine SNS use during a task and its influence on the performance of that task. In this experiment, the role of SNS in various situations was examined by reviewing the literature on break and performance as well as the types of breaks and tasks. Owing to its exploratory nature, this study used various types of data, such as electroencephalography interpretation data generated from a brain-computer interface, self-reported data, and data recorded by a computer. Those participants who used SNS showed an improved performance compared with those who took a short break while doing a simple task. Further analysis showed that the degree of SNS usage and engagement with SNS had positive effects on the participants' simple task performance, while social presence and reassurance of self-worth had negative and positive effects on the participants' complex task performance, respectively.

  • The science museum in the past satisfied visitors only by interacting them with simple objects and exhibition, while one in modern times was requested to meet the need of visitors in their engagement in educational programs. To meet the visitors' need, the science museum made efforts to train, educate, and assign docents so that they can interact with visitors and serve the educational purpose of visitation. In this study, we analyzed the strengths and weakness of docent training programs from science museums/science centers nationally and internationally, to make implication on how to design a docent training and professional program. Programs from four national and four international science centers/museums were selected as a sample for analysis. Their docent training programs were compared with the data of surveys and interviews and emails from docents and docent managers/evaluators. Artifacts and documents of the docent training programs were also collected and used to construct the validity in analyzing the data, resulting in the well-developed docent training program as the critical one for enriching science museum education. The results included; First, we need to recruit and train docents who interact visitors directly but they need to be differentiated from regular volunteers for promoting science museum education for the purpose of popularization of science. Additionally, Second, we need to develop and run docent training program where docents can experience 'informal learning' exhibition interpreting strategies through the real field from mentoring from the experienced/senior docents beyond 'formal learning' exhibition content. Third, we need to equip docents with skills to make scientific literacy possible at science museum-such as experiencing scientific ethics through scientific inquiry-which happens limited at school education.

  • The purpose of this study is to examine whether and how the features of performance assessments implemented during integrated science classes are related to teachers' PCK. We observed and video recorded four high school teachers' performance assessment practices, interviewed them, and surveyed their PCK. An analysis of the data shows that the teachers' performance assessment practices differed in terms of assessment of process, diagnosis of student learning progress, feedback, degree of classroom interactions, and use of assessment criteria. In particular, the opportunities for students to participate in assessment actively and use of assessment for learning varied across teachers. Also, relational patterns among science teaching orientations, PCK and performance assessment practices were found. When a teacher aimed at teaching for both academic learning and scientific literacy, sophisticated PCK was shown and assessment practices were complex accordingly. When scientific literacy was emphasized PCK highlighted experiential learning and assessments were not clearly distinguished from learning activities. In contrast, when academic achievement was emphasized traditional teaching strategies and assessments were highlighted. Based on these findings a number of topics for professional development are suggested including strategies for students' active engagement in assessment, use and development of specific assessment criteria, strategies for assessing performance qualities, and intuitive assessment competency development. Further research topics are also suggested.

  • This article examines K-8 pre-service teachers' (PSTs) engagement in lesson plan modification using the eight Mathematics Teaching Practices (MTPs) in Principles to Actions, the most recent landmark publication of framework by National Council of Teachers of Mathematics (NCTM) in the U.S. The activity consisted of four phases that involved the analysis and modification of an existing lesson plan. Fifty-seven PSTs participated in the activity throughout the semester, and data from each phase was analyzed using the inductive content analysis approach. PSTs' initial conceptions of lesson planning reflected little on teaching practices (i.e., the MTPs) with more emphasis placed on the form - rather than function - of lesson elements. With the opportunity to interpret MTPs and analyze lesson plans using MTPs as an analytical lens, PSTs demonstrated various interpretations of MTPs, made efforts to incorporate MTPs into lessons, and attended to the interwoven nature of MTPs. This article also shares the challenges, conflicts, and tensions reported by PSTs during their participation of lesson plan modification; as such, the results from this study will inform the research examining the pedagogical (im)possibilities for utilizing MTPs in mathematics teacher training programs.

  • Even though titanium(Ti) and its alloys are the most used dental implant materials, there are some problems that Ti wears easily and interferes normal osteogenesis due to the metal ions. Ti coated with bioactive ceramics such as hydroxyapatite has also such problems as the exfoliation or resorption of the coated layer, Recent studies on implant materials have been proceeding to improve physical properties of the implant substrate and biocompatibility of the implant surfaces. The purpose of the present study was to examine the physical property and bone tissue compatibility of bioinert nitrides ion plated Ti, Button type specimens(14mm in diameter, 2.32rrun in height) for the abrasion test and cytotoxicity test and thread type implants(3.75mm in diameter, 6mm in length) for the animal experiments were made from Ti(grade 2) and 316LVM stainless steel. Ti specimens were ion plated with TiN, ZrN by the low temperature arc vapor deposition, and the depth profile of the TiN/Ti, ZrN/Ti ion plated surface was examined by Auger Electron Spectroscopy. Three kind of button type specimens .of TiN/Ti, ZrN/Ti and Ti were used for abrasion test, and HEPAlClC7 cells and CCD cells were cultivated for 4 days with the specimens for cytotoxicity test. Thread type implants of TiN/Ti, ZrN/Ti, Ti, 316LVM were implanted on the femur of 6 adult dogs weighing 10kg-13kg. Two dogs were sacrified for histological examination after 45 days and 90 days, and four dogs were sacrified for the removal torque test of the implant') after 90 days. The removal torque force was measured by Autograph (Shimadzu Co., AGS-1000D series, Japan). Abrasion resistance of TiN/Ti was the highest, and that of ZrN/Ti and Ti were followed. The bioinert nitride ion plated Ti had much better abrasion resistance, compared with Ti, In the cytotoxicity test, the number of both cells were increased in all specimens, and there were no significant difference in cytotoxic reaction among all groups (p>0.1), In histological examination, 316LVM showed the soft tissue engagement in interface between the implant and bone, but the other materials after 45 days noted immature new bone formation in the medullary portion along the implant surface, and those after 90 days showed implant support by new bone formation in both the cortical and the medullary portion, The removal torque force of Tilv/Ti showed significantly higher than that of Ti(p(O,05). The difference in removal torque force between TiN/Ti and ZrN/Ti was not significant(p>0.05), and that of 316LVM was lowest among all groups(p<0.05). These results suggest that bioinert nitrides ion plated Ti can resolve the existing problems of Ti and bioactive ceramics, and it may be clinically applicable to human.

  • Central Asia has great growth potential for cooperation as the Korean Official Development Assistance (ODA) program expands and diversifies. In the case of the forest sector, Korea's successful greening experience has attracted interest from countries in Central Asia. In particular, the depletion of the Aral Sea and a widespread environmental degradation should motivate regional cooperation as well as highlights the need to establish a multilateral cooperative system. The limitation of existing bilateral cooperation, which is the limitation of South-South cooperation, is underscored by the engagement of new donors or the multilateral cooperation and triangular cooperation of organizations is receiving new attention. In addition, Central Asia is suitable for implementing the basic concepts of triangular cooperation. Korea is able to make complementary regional agreements using friendly partnerships with Kazakhstan (the Emerging Donor) and Uzbekistan (the second South Korean Focus Country of ODA). To reinterpret the basic concept of triangular cooperation, three regional cooperation strategies for Central Asia are proposed in this study: windbreak forest development to guarantee resident settlement, resident income increase, and protection of the Aral Sea from further degradation.

  • Information and communication technologies (ICT) have been combined with products from other industries to provide new functionality, as recently shown in the cases of Internet of Things (IoT). Modularity assumes a crucial role in such technological convergence, and has impacts on the relationship between organizations as well as competition within an industry. Interface standards, which ensure the connectivity between modules, serve as a critical factor in the process by which modularity affects organization systems and industry structure. To understand the aforementioned phenomenon, we studied modularity and interface standards with a focus on the interaction between technology and organization systems and subsequent changes in industrial dynamics. This paper examines previous literature on modularity and interface standards in the aspects of product architecture, organization systems, and institutional factors. With this analytical framework, we conducted a comparative analysis of electronic and automotive industries to derive implications for standardization policy. This research has shown the significance of external open interface standards in shaping an industrial landscape where a variety of module producers horizontally compete. It also advises that policymakers take into account product characteristics, engagement of leading firms in an industry, and institutional factors such as WTO law in the design of standardization policy.
