본 연구는 아바타 꾸미기에 특화된 제페토 이용자 201명을 대상으로 이들의 정체성을 반영하는 아바타의 유형에 따라서 이용자들의 미디어 경험이 어떻게 차별화 되는지를 사회적 실재감과 플로를 통해서 분석하 였다. 특히 사회적 공간으로서 메타버스에서의 플로 경험은 타 아바타와의 상호작용을 통해서 이루어진다 는 점에서 사회적 실재감의 매개 효과를 논의하였다. 연구 결과는 다음과 같다. 첫째, 아바타를 나와 비슷 하다고 생각하는 집단에서 더 많은 사회적 실재감과 플로를 경험하고 있으며, 아바타는 나와 다르다고 생각하는 집단에서는 플로의 하위요인 중 몰두는 통계적으로 유의미하지 않았다. 둘째, 사회적 실재감의 하위요인 중 상호이해와 정서적 유대감은 매개변인으로 플로에 영향을 미치는 반면 공동 공간감은 통계적 으로 영향력이 없었다. 본 연구는 상호이해와 정서적 유대감이 이용자의 플로 형성에 영향력을 발휘하고 있다는 점에서 사회적 상호작용이 메타버스 서비스에 있어서 중요하게 논의될 필요가 있음을 시사한다.

Background: The increasing prevalence of smartphone use has been associated with musculoskeletal pain; however, the specific roles of demographic factors, smartphone usage time, posture, contents and state of addiction on pain in the upper-body regions remain unclear. Objects: This study investigated the influence of smartphone usage characteristics, including age, occupation, visual condition, duration, content, and posture, as well as smartphone addiction, on musculoskeletal pain in upper-body regions. This study aimed to comprehensively elucidate the factors contributing to the pain associated with smartphone use. Methods: A cross-sectional survey was conducted with 316 participants aged 20–59 years. Data on personal characteristics, smartphone use patterns, state of addiction (measured using the Smartphone Addiction Scale-Short Version), and musculoskeletal discomfort (Cornell Musculoskeletal Discomfort Questionnaire and Cornell Hand Discomfort Questionnaire) were collected. Binary logistic regression analysis identified significant predictors of pain in different body regions. Results: Younger age (20–30 years), being housewives or students, and vision impairment (shortsightedness) significantly increased the likelihood of neck, shoulder, and hand pain. Prolonged smartphone use (7–10 hours daily) and gaming were strongly associated with elevated pain risk, whereas moderate usage (1–4 hours daily) may be protect against lumbar pain. Non-neutral postures, especially side lying, have emerged as critical risk factors, with left-side lying linked to hand pain and right-side lying linked to upper back pain. Smartphone addiction consistently predicted pain across all regions by amplifying physical strain through prolonged engagement and poor posture. Conclusion: This study highlighted the multifactorial nature of smartphone-related musculoskeletal pain, emphasizing the roles of demographic characteristics, usage patterns, and addiction. These findings provide a foundation for developing tailored ergonomic and behavioral interventions to mitigate pain risks, particularly in high-use populations. Future research should validate these findings through longitudinal studies and objective measures.

The value-laden nature of knowledge means that the process of knowledge transmission carries significant regional imprints. In higher education discipline instruction, how the presence of the state is realized has become a topic worth discussing. This article reviews the development history, current trends, and challenges faced by sociology education in Chinese universities. The research finds that the presence of the state is significantly evident in sociology education at Chinese universities. In the practice of sociology education, there exists a synergistic operation of three logics: institutional logic, professional logic, and educational logic. Among these, institutional logic is the core logic in the implementation process of sociology education, professional logic is the foundational logic in the operational process of sociology education, and educational logic is the formal logic in the practice process. The disciplinary ideals and patriotic sentiments determine the value basis for the synergistic operation of these three logics. The presence of the state functions through the diffuse form of institutional logic, embedding the value-laden nature of knowledge through the coding process into the professional logic, and then realizing it through the educational logic.

본고는 질 들뢰즈와 펠릭스 과타리의 ‘소수성’ 이론에 천착하여 옌롄커의 ｢골수｣,  일광유년, 레닌의 키스 등을 분석하였다. 구체적으로 이 작품들에 나타나는 정치적 폭력성, 권력의 폭압, 사회적 비윤리성, 사회의 모순적 구조를 분석함으로써, 소수자로 서 장애인의 존재 방식을 고찰하였다. ｢골수｣에서는 가난, 무지, 유전적 문제, 그리고 최소한의 교육 및 의료 혜택조차 받지 못한 채, 가족의 일방적인 희생을 강요받는 피 동적인 존재로서의 장애인의 모습을 보여준다. 일광유년에서는 사회와 권력자의 잘 못된 판단으로 인해 장애인들의 상호 연대가 무너지는 과정을 그려내며, 사회의 모순 과 비윤리적이고 부조리한 구조를 드러낸다. 마지막으로 레닌의 키스에서는 자신의 장애를 드러내고 연대했던 장애인이, 결국 물질만능주의와 장애인에 대한 인권 및 인 식 교육의 부재로 인해 고통받는 존재로 변해가는 과정을 묘사하고 있다.

This study aims to develop effective strategies for stimulating seafood consumption in the growing young children market, particularly at a time when interest in healthy eating is increasing. To achieve this, data from the 2023 survey on changes in seafood consumption behavior of 1,000 domestic consumers by the Korea Disease Control and Prevention Agency were utilized. The analysis was conducted using an ordered probit model, along with T-tests and chi-square tests to examine the determinants of seafood consumption. The results indicated that the presence of young children in a household significantly influences seafood consumption. This is largely due to the perception that seafood is beneficial for the health and safety of infants and toddlers. Households with young children prioritize food safety and convenience, showing a preference for pre-processed seafood, while households without young children tend to purchase unprocessed seafood and prepare it themselves. This study highlights the impact of having young children on seafood consumption and purchasing behavior, providing valuable insights for the development of targeted seafood marketing strategies and policies.

The Metaverse’s virtual world is used in various industries and is expected to continue to grow in the future. In addition, the Metaverse is a new type of society that integrates various new technologies, and NFT products play an essential role. Therefore, NFT product characteristics and industry trends should be assessed to revitalize the NFT market. To this end, this study confirms the influence relationship between social presence and NFT product characteristics in the Metaverse environment and examines the impact of each characteristic on consumer satisfaction and continued engagement intention to NFT product. Statistical analysis such as exploratory factor analysis, reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling (SEM) using IBM SPSS Amos was conducted on data collected through a survey targeting male and female Korean consumers in their age group 10 to 50. Study results indicate that social presence significantly impacted all characteristics of NFT products (authenticity, scarcity, rarity, collectability, and interactivity). Scarcity and authenticity significantly impacted consumer satisfaction, and both authenticity and consumer satisfaction significantly impacted continued engagement intention. Thus, effective product development and marketing strategies can be established only by presenting different emphasized characteristics depending on the type of NFT product and the Metaverse’s social presence.

촉각과 정서에 관해 이루어진 선행 연구들에서는 어떤 촉각 자극이 특정 정서를 유발하는가에 초점을 맞춰 진행되 었다. 또한, 시각이 촉각 지각의 과정에서 중요한 역할을 함에도 불구하고 촉각의 단일 양상에만 주목하여 연구가 진행되었다. 이에 본 연구에서는 촉각 자극을 활용하여 거칠기, 경도, 시각 차단 여부라는 세 가지 변인이 촉각 지각 에 따른 정서 경험에 미치는 영향을 알아보고자 하였다. 실험 자극은 일상생활에서 접할 수 있는 사물을 사용하였으 며, 거칠기 2조건(거친, 매끄러운), 경도 2조건(단단한, 부드러운)을 교차하여 ‘거친/단단한’, ‘거친/부드러운’, ‘매끄러 운/단단한’, ‘매끄러운/부드러운’이라는 4가지 조건에 맞게 선정하였다. 실험은 시각 차단 여부에 따라 두 세션으로 구분되었다. 참가자들은 촉각 자극을 보지 않으면서 만진 뒤에 평정하는 세션을 마치고, 촉각 자극을 보면서 만진 뒤에 평정하는 세션을 진행하였다. 반복측정 변량분석 결과, 보면서 자극을 만질 때 더 긍정적으로 느끼며, 보지 않으면서 자극을 만질 때 더 부정적으로 느낌을 확인하였다. 또한 매끄러운 자극과 부드러운 자극을 더 긍정적으로 느끼고 거친 자극을 더 부정적으로 느꼈으며, 이 경향이 보지 않고 만졌을 때 더 강했다. 본 연구의 결과는 시각 정보가 제공되는 경우와 제공되지 않는 경우 촉각 경험에 대한 정서 반응이 어떻게 다른지를 이해함으로써, 정서와 시각 정보 처리 간의 상호작용에 대한 이해를 높일 수 있다는 시사점을 가진다.

This study analyzed the impact of Higher-order resources on profit sustainability for domestic companies using a mathematical statistical model. Higher-order resources refer to resources that do not directly affect profits but influence other resources that directly contribute to profits. As a result of analysis using 30 years of actual data from more than 650 domestic companies, the average duration of competitive advantage including high-order resources was found to be about twice as long as the period suggested by the autoregressive model excluding high-order resources. Through this, if companies want to earn more profits over a long period of time than their competitors, they must not only possess resources that are more valuable, rare, difficult to imitate, and non-substitutable compared to their competitors, but also that higher-order resources can contribute to changes in these resources over time. It was confirmed that it must lead the long-term profit difference. High-level resources include strategic planning, mergers and acquisitions (M&A) capabilities, and good forecasting.

The disposal of organic pollutants is one of the important research topics. Some of the studies in this field are based on the degradation of organic pollutants with a catalytic agent. The cobalt tetraoxide/peroxymonosulfate system is an important catalytic system used for the radical degradation of organic pollutants. To increase the catalytic efficiency of such reactions, graphitization of activated carbon used as a support solid and nitrogen doping to the carbon structure are commonly used methods. In this study, cobalt tetraoxide production, N-doping and graphitization were carried out in a single step by heat treatment of activated carbon doped with the phthlocyanine cobalt (II) complex. The catalytic performance of the catalyst/ peroxymonosulfate system was investigated by changing the pH, catalyst, and PMS concentration parameters on rhodamine B and 1,3,5 trichlorophenol, which were used as models. It was seen that the catalysts had 97% activity on rhodamine B in 16 min and 100% on 1,3,5 trichlorophenol in 6 min. It was observed that the catalysts continued to show high catalytic activity for five cycles in reusability studies and had a very low cobalt leaching rate. These results are in good agreement with previously published studies. In line with these results, the synthesized N-doped graphitic carbon/Co3O4 catalyst can be used as an effective catalyst for wastewater treatments.

This study examines the effect of visual tactile and presence of VR fashion stores on consumer attitude via consumer surveys. Visual tactile and presence positively influence consumer experience which includes fantasy, feeling, and fun. In addition, these three experiences positively affect consumer attitude. The moderating effect of cyber motion sickness is discussed. Academic and practical implications for digital fashion are provided.

Imagination plays a critical role in travel decision-making. Given the intangible nature of tourism products, tourists cannot directly experience and evaluate the tourism resources in advance. Thus, tourists must first mentally predict and imagine the future travel experiences and scenarios in the destination based on the marketing information (e.g., travel photo, promo video) and prior knowledge, then form their subjective evaluation of the travel product. This future-thinking process is called “mental simulation”. Stacks of research have shown that mental simulations positively affect travel behavior (Le et al., 2019). However, given that travel is a kind of novelty-seeking activity, tourists are usually not familiar with the destination environment and activities. The lack of prior knowledge might inhibit their mental simulation process, even if destination photos and videos are provided. Thus, how to effectively arouse tourists’ mental simulation of destination experience is an important question for effective tourism marketing.

In recent years, with its amazing online interactive promotion ability, e-commerce live streaming has attracted the attention of theoretical scholars and practical experts. This study takes “co-presence (CP) ” and “social presence (SP) ”, which are the prominent features of e-commerce live streaming, as the breakthrough point to explore the mechanism of the influence of co-presence and social presence on purchase intention. In this study, consumers with e-commerce live streaming watching experience are taken as participants, and the method of structural equation modeling is used. It is found that: presence significantly impacts flow experience and consumer purchase intention, while the impact of the two kinds of presence (SP, CP) is variable. the promotion effect of the two kinds of presence (SP, CP) on consumer purchase intention is completely mediated by flow experience. The mediating effect of co-presence on consumer purchase intention through flow experience is regulated by e-commerce live streaming topicality, but social presence doesn’t.
