With the advent of Metaverse, a promising new era for business on virtual reality (VR) platforms has dawned. In this rapidly expanding Metaverse platform, the potential for virtual fashion marketing through avatars is vast, with leading fashion brands already making strides by creating virtual fashion stores or hosting virtual fashion shows. However, the research on fashion-related industries in this newly emerging virtual world platform is still in its infancy. This study sought to identify the relationship between the characteristics of the Metaverse and the factors that influence how the perceived value of virtual fashion products affects purchase intention. A survey was conducted with three hundred Korean respondents, and the hypothesis was verified through analysis using the SPSS statistical program. Our analysis revealed that the sense of presence significantly influences the value of fashion products on the Metaverse platform. As a result, the sense of presence significantly influenced the emotional, visual authority, and economic value of the avatar virtual fashion perceived by users. Second, enjoyment, visual authority, and economic value influence users' intention to purchase virtual fashion items. In addition, all of these perceived value factors were confirmed to have a significant partial mediating effect on the impact of the presence of the Metaverse platform on the purchase intention. Through this study, we empirically analyzed the causal relationship between the characteristics of the Metaverse platform and the virtual fashion experience using avatars - a topic that has yet to be covered. We formed new insights into virtual fashion consumption, providing primary data for related research streams. Our survey respondents consisted only of those with recent Metaverse experience, so the research results were highly effective.

The main purpose of this study isto explore the potential of affective computing (AC) platforms in education through two phases ofresearch: Phase I - platform analysis and Phase II - classification of academic emotions. In Phase I, the results indicate that the existing affective analysis platforms can be largely classified into four types according to the emotion detecting methods: (a) facial expression-based platforms, (b) biometric-based platforms, (c) text/verbal tone-based platforms, and (c) mixed methods platforms. In Phase II, we conducted an in-depth analysis of the emotional experience that a learner encounters in online video-based learning in order to establish the basis for a new classification system of online learner's emotions. Overall, positive emotions were shown more frequently and longer than negative emotions. We categorized positive emotions into three groups based on the facial expression data: (a) confidence; (b) excitement, enjoyment, and pleasure; and (c) aspiration, enthusiasm, and expectation. The same method was used to categorize negative emotions into four groups: (a) fear and anxiety, (b) embarrassment and shame, (c) frustration and alienation, and (d) boredom. Drawn from the results, we proposed a new classification scheme that can be used to measure and analyze how learners in online learning environments experience various positive and negative emotions with the indicators of facial expressions.

Understanding teachers in the early childhood education is crucial as it can not only affect the quality of children's education but also cause many critical problems such as child abuse. A significant amount of research work has been made on the use of robots in childcare classrooms. The finding from the research has shown many advantages such as the improvement of learning performance, social/emotional skills, creativity, concentration period, physical and cognitive development. However, most of the study has been implemented at the K-12 classrooms but not much has been focused on the education at the early childhood classrooms. Importantly, it is very crucial to understand teachers' perception, demands and technical competence about the new teaching tool, in order to maximize its educational effect. This paper investigates some critical issues existing in both teaching and managing in the early childhood education. It will also explore teachers' perceptions and expectations on the use of robots to identify some dilemmas that exist in their working and teaching environment. A survey study was conducted with 119 early childhood educators in South Korea. It analyzed the educators' perception of using robots to improve their teaching performance and to make better outcomes for children, investigated job satisfaction and difficulties that they have in the current work environment. This paper concludes with several guidelines for integrating and setting robotics in the early childhood environment, in order to engender productive outcomes for the future early childhood education.

Purpose: Gardening has been reported to have positive emotional and physical effects in older adults. However, limited studies have assessed this relationship in Korea. Therefore, in this pilot study of densely populated urban dwellers, we aimed to investigate whether temporary but repeated experiences of the natural environment could positively change metabolism-related blood indicators. Methods: This study used pre- and post-interventional designs to investigate the effects of 16 weeks of gardening on lipid profiles in an urban adult population and investigate their relationships. This study was conducted 30 times at the H Botanical Garden in Yongin City from August 16, 2021 to November 30, 2021 (16 weeks, twice a week, 3 hours each time). Before and after the gardening program, a clinical pathologist collected blood samples from the participants. Results: High-density lipoprotein levels increased, low-density lipoprotein levels decreased, and total cholesterol levels decreased after the gardening activity. Conclusions: Our findings suggest that gardening has potential for clinical application as it has good control over the lipid profile through physical activity. These findings can be used as basic data for studying the relationship between urban populations and their living environment and for various studies in the future as experiencing the natural environment provides many health benefits.

Looking at the recent game market, classic games released in the past are being re-released with high-quality visuals, and users are generally satisfied. It can be said that the realization of realistic digital actors, which was not possible in the past, is now becoming a reality. Epic Games launched the MetaHuman Creator website in September 2021, allowing anyone to easily create realistic human characters. Since then, the number of animations created using MetaHumans has been increasing. As the characters become more realistic, the movement and expression animations expected by the audience must also be convincingly realized. Until recently, traditional methods were the primary approach for producing realistic character animations. For facial animation, Epic Games introduced an improved method on the Live Link app in 2023, which provides the highest quality among mobile-based techniques. In this context, this paper compares the results of animation produced using both keyframe facial capture and mobile-based capture. After creating an emotional expression animation with four sentences, the results were compared using Unreal Engine. While the facial capture method is more natural and easier to use, the precise and exaggerated expressions possible with the keyframe method cannot be overlooked, suggesting that a hybrid approach using both methods will likely continue for the foreseeable future.

이 논문은 지역 지상파와 케이블 지역채널의 시너지를 통한 방송 지역성의 극대화 가능성을 모색한다. 이를 위해 4차 산업혁명으로 대별되는 시대적 환경 변화 속에서 지역성 개념이 갖는 유의미성을 검토하고, 방송 지역성의 현재적 상황과 케이블 지역채널에 관한 기존 논의의 지형을 분석한다. 이를 통해 그간 이질적 유형의 사업자로 동떨어져 존재한 지역 지상파와 케이블 지역채널이 지역성 향상을 위해 유기적으로 연계할 수 있는 가능성을 탐색한다. 권역의 규모와 편성시간의 상이성은 두 매체의 시너지를 위한 최적의 조건을 구성한다. 이에 따른 쟁점으로 무료 보편적 성격이 강한 지역 지상파와 유료방송인 케이블 지역채널을 동일한 법체계로 묶는 것의 적합성과 현실성 문제를 논하며, 케이블 지역채널을 공적 범주로 제도화하는 데 있어서 가장 큰 걸림돌이 정서적 거부감에서 비롯함을 밝힌다. 이를 타개하기 위한 당면과제로 현재의 정책기조인 동일 서비스 동일 규제에 입각한 유료방송 일원화와 케이블 SO 지역사업권 폐지의 폐기, 지역채널의 해설 논평 허용, 종합유선방송사업자의 자체 역량 강화를 제시한다.
