The purpose of this study is to examine the factors influencing the intention to use the Metaverse from various angles based on the Extended Technology Acceptance Model and Value-based Adoption Model. Specifically, we examined whether there is a difference in perception of the Metaverse and in factors affecting the intention to use the Metaverse between the Metaverse experienced and non-experienced. For this purpose, the variables were classified into the technical characteristics of the Metaverse (interactivity, content quality), perceived benefits (perceived usefulness, perceived enjoyment), and perceived sacrifices (perceived risk, perceived complexity) and a survey was conducted with university students. The findings of this study indicate that the perceived interactivity, usefulness, and enjoyment of the Metaverse had a major impact on the intention to use the Metaverse for those without Metaverse experience, whereas enjoyment of the Metaverse had the greatest impact on the intention to use the Metaverse for those with Metaverse experience. Based on the study results, we provided marketing strategy implications for continuous growth and development of the Metaverse industry.

Recent research on soft adhesives has sought to understand in depth how their chemical or mechanical structures interact strongly with living tissues. The aim is to optimally address the unmet needs of patients with acute or chronic diseases. Synergy adhesion, which includes both electrostatic (hydrogen bonds) and mechanical interactions (capillary stress), appears to be effective in overcoming challenges related to long-term unstable bonds to wet surfaces. Here, we report electrostatic and mechanically synergistic mechanisms of adhesion without chemical residues. To infer the mechanism, a thermodynamic model based on custom combination adhesives has been proposed. The model supported experimental results that thermodynamically controlled swelling of hydrogels embedded in elastomeric structures improves biofluidic insensitive on-site adhesion to wet surfaces and improves detachment without chemical residues in the direction of peeling.

The prevention of marine accidents has been a important topic in marine society for long time, and various safety policies and countermeasures have been developed and applied to prevent those accidents. In spite of these efforts, however, significant marine accidents have taken place intermittently. Ship is being operated under a highly dynamic environments, and many factors are related with ship's collision, whose factors are interacting. So, the analysis on ship's collision causes are very important to prepare countermeasures which will ensure the safe navigation. This study analysed the ship's collision data over the past 10 years(1991-2000), which is compiled by Korea Marine Accidents Inquiry Agency. The analysis confirmed that‘ship's collision’is occurred most frequently and the cause is closely related with human factor. The main purpose of this study is to analyse human factor. For this, the structure of human factor is analysed by the questionnaire methodology. Marine experts were surveyed based on major elements that were extracted from the human factor affecting to ship's collision. FSM has been widely adopted in modeling a dynamic system which is composed of human factors. Then, the structure analysis on the causes of ship's collision using FSM are performed. This structure model could be used in understanding and verifying the procedure of real ship's collision. Furthermore it could be used as the model to prevent ship's collision and reduce marine accidents.

The purpose of this study is to shed light on the relationship between perceived value(PV), attitude toward the exhibition(ATYCSE), and behavioral intention toward the exhibition(BITYCSE) through literature review and quantitative research, focusing on <Yumi's Cells Special Exhibition (2020)> as an Instagrammable exhibition. The exhibition has strong entertainment experience quality, and taking pictures has a positive correlation with the satisfaction as well as the immersion, while sharing the viewing experience on Instagram does not influence on the ATYCSE in terms of the PV. Satisfaction also has meaningful correlations with the immersion and the detail factors of BITYCSE. In particular, it can be confirmed that the storytelling factor occupied a superiority over the exhibit factors or the exhibition environment of the Instagram-friendly exhibition, and through this, the importance of storytelling was confirmed. This research unveils implications for the influence of the interactivity and participatory features of the Instagrammable exhibition on the ATYCSE as a potential factor of PV, and the importance of storytelling in Instagrammable exhibitions.

The purpose of this study was to investigate the effect of perceived risk on continuous usage intention of Internet primary banks and to verify moderating effects of acceptance factors affecting customers' acceptance of Internet primary banks on the relationship between perceived risk and continuous usage intention. The study aims to find ways to cope with perceived risk and strategic measures of intention in order to increase the intention to continuous usage intention of Internet primary banks. For the analysis, interaction effect were conducted among a total of 457 surveys. As a results, First, perceived risks, acceptance factors and continuous usage intention of the customers of Internet primary banks were significantly correlated. Second, the types of perceived risks which have a significant effect on continued usage intention of Internet primary banks were found to be perceived financial and functional risks. Third, respect to moderating effects of moderator variables, usefulness was found to have a significant moderating effect on the relationship between perceived security risk and continuous usage intention. In addition, ease of use was shown to have a significant moderating effect on the relationship between each type of perceived risks and continuous usage intention. This study attempted to explore and seek strategies to reduce perceived risks and strategic plans for acceptance factors to increase continuous usage intention of Internet primary banks.

With the explosion of SNS(social network services) users, the social commerce market has emerged as a new consumer market, and will continue to grow in recent years. Despite the market environment, however, studies are lacking as to the causes of frustration that are hurting social commerce activation. This study is based on the 'Hezbollah' 2 Factor Theory and is a study of social commerce users' satisfaction and frustration factors. For this purpose, social commerce site characteristics and user characteristics were first derived from interviews and literature reviews to confirm their relationship to satisfaction and dissatisfied products. The results showed that the price discount rate, diversity, regional infrastructure, and e-commerce familiarity resulted in the impact on the definition of satisfaction, while the price discount rate, interoperability and innovation resulted in the definition of unsatisfactory goods. It also showed that satisfaction affects the definition of intended use. In particular, the price discount rate was found to be the only factor affecting the definition of unsatisfactory as well as affecting the definition of satisfaction.

In this age of the $4^{th}$ industrial revolution, we, science educators, are giving more light on students' agentic behavior in the process of educating future scientist. This study, with the analytic lens of epistemic agency, explores the key stages of a student-driven R&E program rather than the scientist-led R&E program. It also examines to understand the emergence of students' epistemic agency in each stage of R&E. Data from participant observation for 18 months and in-depth interviews were collected and analyzed with the constant comparative method of grounded theory. This study identifies and describes five key stages of student-driven R&E: The stage of exploring research theme, designing research, performing lab activity, interpreting results, and communicating research. It also finds that (a) students' epistemic agency emerged with the constant interactions with the R&E structure; (b) students' epistemic agency has deep relations with the epistemic beliefs of the students; (c) students positioned themselves as decision-makers in the R&E practice; (d) the redistributed power and authority of the R&E contributed to the emergence of students' epistemic agency.

A 2(pedagogical agent: with vs. without) × 2(on-screen text: with vs. without) between-subject design was used in this study to investigate the effects of pedagogical agent and redundant on-screen text on video learning. In the case of the educational video without redundant on-screen text, there was no difference in social presence, satisfaction, and intention to continue learning regardless of the presence of a pedagogical agent. However, when the educational video contained redundant on-screen text, participants who watched educational video with pedagogical agent perceived higher social presence, satisfaction and intention to continue. In terms of academic achievement, no difference was found whether redundant on-screen text was contained or not. It supports some of the previous studies on the reverse-redundancy effects, suggesting that the inclusion of redundant text does not necessarily cause the reduction of learning outcomes. Video learning shows a higher dropout rate than face-to-face learning. Therefore, it is particularly important to understand how to strengthen interactions with learners and motivate them to keep themselves engaged in learning. This study discussed whether pedagogical agent and on-screen text are factors that induce continuous participation of learners in video learning.
