The thermoelectric effect, which converts waste heat into electricity, holds promise as a renewable energy technology. Recently, bismuth telluride (Bi2Te3)-based alloys are being recognized as important materials for practical applications in the temperature range from room temperature to 500 K. However, conventional sintering processes impose limitations on shape-changeable and tailorable Bi2Te3 materials. To overcome these issues, three-dimensional (3D) printing (additive manufacturing) is being adopted. Although some research results have been reported, relatively few studies on 3D printed thermoelectric materials are being carried out. In this study, we utilize extrusion 3D printing to manufacture n-type Bi1.7Sb0.3Te3 (N-BST). The ink is produced without using organic binders, which could negatively influence its thermoelectric properties. Furthermore, we introduce graphene oxide (GO) at the crystal interface to enhance the electrical properties. The formed N-BST composites exhibit significantly improved electrical conductivity and a higher Seebeck coefficient as the GO content increases. Therefore, we propose that the combination of the extrusion 3D printing process (Direct Ink Writing, DIW) and the incorporation of GO into N-BST offers a convenient and effective approach for achieving higher thermoelectric efficiency.

Structural inversion refers to the reverse reactivation of extensional faults that influence basin shortening accommodated by contractional faults or folds. On the Korean peninsula, Miocene inversion structures have been found, but the Cretaceous rocks on Geoje Island may have undergone inversion as early as the Upper Cretaceous. To evaluate the structural inversion on Geoje Island, located on the eastern side of South Korea, and to determine the effects of preexisting weakness zones, field-based geometric and kinematic analyses of faults were performed. The lithology of Geoje Island is dominated by hornfelsified shale, siltstone, and sandstone in the Upper-Cretaceous Seongpori formation. NE and NW-oblique normal faults, conjugate strike-slip (NW-sinistral transpressional and E-W-dextral transtensional) faults, and NE-dextral transpressional faults are the most prominent structural features in Geoje Island. Structural inversion on Geoje Island was evidenced by the sinistral and dextral transpressional reactivation of the NW and NE-trending oblique normal faults respectively, under WNW-ESE/NW-SE compression, which was the orientation of the compressive stress during the Late Cretaceous to Early Cenozoic.

The Korea Strait comprises a continental shelf in a shallow sea that experienced glacio-eustastic sea-level changes during the Quaternary period. A long core of 76.6 m in length was acquired at the South Sea Drilling Project site (SSDP-101; 34o19.666′E and 128o16.335′N) with a 60 m water deep. The uppermost massive sand beds were interpreted as sandy sediments of the nearshore marine sand ridge in the shallow sea during the transgression of sea level, whereas the lower parts of alternating sandy and muddy beds were interpreted as deposits in marsh, estuary, and tidal flat environments. A three-layered geoacoustic model was reconstructed for the sedimentary succession in the high-resolution seismic profile based on a 140-grain size and sediment type of core SSDP-101. For the actual underwater simulation and experiments, the in-situ P-wave speeds were calculated using the sound speed ratio of the Hamilton method.

Background: In terms of physical performance, elastic tape (ET) is known to contribute to injury prevention and performance enhancement. Objects: This study aimed to compare and analyze the effect on lower extremity muscle activity of young adult women with and without ET during squats. Methods: In this study, six healthy, young women were recruited as participants in a university laboratory. Participants were allocated to two groups of three after measuring muscle activity in a pre-test, and the experiment was conducted for a total of two weeks (two sessions). First, 10 half squats were taped once in the first week, and 10 half squats were performed without taping in the second week. The other group did this in reverse and measured muscle activity after the squat was over. Results: As a result of this study, there was no significant difference in the quadriceps with or without ET (Z = –0.11, p > 0.05). Similarly, no significant difference was found in hamstring (Z = –0.31, p > 0.05). Conclusion: No beneficial effect was found on changes in muscle activity following ET application during squats. Further studies require randomized controlled trials that increase the number of participants and the intensity of the intervention, and measure pain, function, and performance rather than muscle properties depending on the biomechanical lifting mechanism.

Technosignature, previously known as SETI(search for extraterrestrial intelligence), is the scientic evidence of past or present extraterrestrial civilizations. Since NRAO's Project Ozma was performed in 1960, most of the noticeable technosignature searches have been done by radio telescopes, hoping to find strong and narrow bandwidth signals that cannot be explained by known natural processes. Recently, the Breakthrough Listen project has opened a new opportunity for technosignature by utilizing both optical telescopes, radio telescopes, and next-generation radio telescope arrays. In this review, mainly based on NASA Technosignatures Workshop (2018), we review the current trends of technosignature surveys, as well as other possible methods for detecting technosignature. Also, we suggest what the Korean community could contribute the technosignature research, including the new SETI project with Korea VLBI Network (KVN).

More than 5,000 exoplanets have been detected nowadays. One of the key motivations of exoplanet detection is to understand what physical/chemical conditions of exoplanets are suitable for harboring extraterrestrial life. Such conditions are called \habitability," and most modern studies assume the existence of liquid water as its key factor. In this paper, we review the current status of exoplanet and habitability studies, as well as some future (habitable) exoplanet survey plans, mostly from National Academies of Sciences, Engineering, and Medicine (2018, 2021). Also, we suggest several research items that the Korean astronomy and space science community could contribute to habitability.

This study will investigate the effects of induced awe on ethical tourist behavior. The positive emotion of awe has not been fully investigated in the context of tourism. This study will fill the gap by conducting an experimental design. The purpose of this study is to identify a message type that appeals to awe effectively. This study will be built on the construal theory. We will use a 2 (emotion: positive awe vs. negative awe) × 2 (message appeal: desirability vs. feasibility) between-subject design in study 1 and a 2 (emotion: positive awe vs. negative awe) × 2 (message appeal: desirability vs. feasibility).

This study investigated how immersive VR store experience generated consumers’ urge to buy via self-imagery and pleasure. It also identified that the processing varied by the level of self-relevance to the VR store. The findings suggest that the impact of VR store experience can be expanded to impulsive/compulsive purchases.

Due to the development of the internet and communications technology, the media market has undergone significant changes in the 2000s. In the past, when the types of media were not diverse, media content was mainly consumed through TV, radio, newspapers, etc., but as varied, it allowed users to watch the content anytime and anywhere. ‘Snack Video’ which is produced in a short length and consumed in commuting time and leisure time, and ‘Snack Culture’ which is a popular lifestyle trend of consuming short-form cultural content, is now widespread. The representative content of snack content is video clips. Various of media provide video clips, such as portal sites, SNS, and TV programs. YouTube is effective in increasing purchases than the other channels. Over-The-Top (OTT) is another pillar of the new media market, which has emerged with the development of the internet and communications technologies.

The demand for knowledge transfer and experience sharing in terms of digital government and smart cities among partner countries has significantly increased. Digital government-related projects have been mainly proposed for the convenience of the system providers for the short-term or one-time instance without considering the mid-term to the long-term direction of digital government in partner countries. Due to this limitation, after the Knowledge Transfer projects are completed, the government partner countries that participated in the projects have examined the Knowledge Transfer projects and need to build improvement plans to promote the related project in efficient, effective, and sustainable ways with mid-term to long-term perspectives. This study focuses on the knowledge transfer projects in the digital government and smart cities that the Korean government and major public institutions carried out and analyses the status of digital knowledge transfer or official development assistance (ODA) projects from 2011 to 2020. In doing so, the study looked into establishing public sector systems such as digital government and smart cities and analysed the current status and research results of domestic and foreign studies related to assessment and diagnosis. Through this, major factors that determine the performance of digital government ODA were identified, and an analysis framework was derived for the analysis of existing cases of digital government knowledge transfer implementation.

The growth of OTT internet and mobile video streaming services is a major development in consumption of global media sport. The online streaming of sporting events has become the important way of copyrights holders to engage sport fans, especially young fans. The most popular live streaming platforms in South Korea, such as NAVER and Africa TV are intervening in coverage rights markets and changing how live sport is experienced and shared across television, computer, tablet and smartphone screens. At the FIFA World Cup Qatar 2022, NAVER's live streaming service reached 121,173,945 cumulative viewers in 64 matches, including the opening ceremony and the final between France and Argentina. Based on suspense theory, this study aimed to examine the factors that influence sport fans’ watching intention to stream online sport. The current study collected the number of cumulative viewers of live streaming from NAVER and Africa TV, for the matches broadcasted across the KBS, MBC, and SBS, a total of 64 matches in the FIFA World Cup Qatar 2022. The results suggest that a measure of the unfolding nature of suspense is a stronger predictor of watching intention than those used previously. The additional measures of suspense that take into account the unfolding events of the contest will be stronger predictors of watching intention than either disposition toward the winning team or closeness of final score.

This study aimed to investigate the viewing experience of Taekwondo competitions, compare and analyze the viewing experience according to the type of Taekwondo competition, derive the viewing experience structure of Taekwondo contents, and confirm the potential of Power Taekwondo as a sustainable sports content developed for the purpose of popularizing Taekwondo.

The FIFA world cup is one of the most popular and widely viewed sporting event, where millions of viewers across the globe tune in to support their country every four years for the chance to win the ultimate football tournament. According to FIFA, the FIFA World Cup Qatar 2022 recorded over 5 billion cumulative views, with the final match estimated to have been watched by more than 1.5 billion viewers live on television. In South Korea, a total of 11.14 million viewers watched the opening match against Uruguay, which was estimated to be a 97% increase in Korean viewership compared to the previous World Cup.

Extant studies assessing determinants of peer-to-peer (P2P) accommodation prices have mainly focused on individual listing-level analysis, with a less attention to inter-regional dynamics between cooperation and competition. While Airbnb has announced how to set a pricing strategy tool called “smart pricing” to help hosts gauge rental rates, many hosts find that its suggesting prices are too low, failing to offer a robust picture of their destination market (Jiang et al., 2022). This calls for a research on how P2P accommodation hosts can benefit from coopetitive pricing strategy – a hybrid behavior of cooperation and competition that occurs among hosts or regions (Chim-Miki & Batista-Canino, 2018).

Metaverse is a virtual world where users can engage in various activities, and its market is expected to grow rapidly in the coming years (Hwang, 2021). Generation Z, also known as digital natives, are heavily involved in social media and often share selfies, making them more sensitive to body image concerns (Ameen, 2022). In the metaverse, users can create customized avatars, allowing them to experience an ideal body image. This study applies the “extraordinary self” theory to avatar creation, a concept that explains how people create an ideal, fantastic, or transcendent self by consuming experiences that set them apart from their mundane real self (Procter, 2021). Based on the theory, this study examines how dissatisfaction with body image of Generation Z can lead to the creation of avatars that manifest an ideal body image, which in turn, can influence self-congruence with the avatar and self-esteem in the metaverse. This study also looks into the possible effects of enhanced self-esteem on user’s intention to purchase virtual products and their loyalty to a specific metaverse platform. Therefore, the following hypotheses are developed.

This study proposes a new collaborative filtering model that integrates Restricted Boltzmann Machines. The proposed two-stage model is applied to household-level supermarket purchase data. Results show that our model fits the data better and outperforms existing collaborative filtering methods in predicting shopping patterns. The proposed model also improves interpretations of market complexity and common causes of coincidence associated with customers’ multi-category purchases.

Emotion AI, a subset of AI that measures, understands, responds to, and elicits human emotions, is an emerging area that has great potential for advertising research and practice. Studies on the applicability of emotion AI in advertising and marketing have been growing in academic journals. This rapidly burgeoning scholarship creates a need for advertising scholars to comprehend the current status of the research on emotion AI in advertising as well as opportunities and challenges that this new technological development will bring to. Thus, this study aims to offer an overview of research on emotion AI in advertising to identify the scope of existing research, gaps in knowledge, and opportunities and challenges that lie ahead.

This research aims to understand how academic articles stimulate knowledge progress by addressing two questions: Does the level of contribution vary between different methods of research (e.g., conceptual, theoretical, and empirical)? How do we assess the potential of scholarly articles to impact and further innovate the field?

In ethical consumerism, the issue of ethical attitudes not translating to ethical behaviors has been highly debated. While previous studies attribute this attitude-behavioral mismatch to the lack of education, hypocrisy, or low commitment, we propose a novel approach of applying Moral Foundation Theory (MFT) to account for the phenomenon. MFT identifies two dimensions of morality: individualizing moral foundations (INDI) which focuses on justice and harm, and binding moral foundations (BIND) which emphasizes authority and loyalty. Using responses from more than 4,000 consumers from four culturally and regionally diverse markets, we investigate the differing roles of moral foundations in response to a scenario on a sweatshop issue of a supplier whose factory is in a developing country. We use the mediator-moderator model of MFT-anticorporate attitude-boycott behavioral intention sequence to examine the differing role of INDI and BIND. Our results show that INDI and BIND are both positively related to anticorporate attitude; However, BIND is negatively related to boycott behavioral intention while INDI is positively related. That is, consumers with a strong BIND may show an attitude-behavioral mismatch although they are highly ethical.

Voice assistant devices (VADs), driven and improved by artificial intelligence, have been adapted for consumers (e.g., Hey Google and Alexa) and are widely used for their daily lives (Guha et al., 2022; Rabassa, Sabri, & Spaletta, 2022). Consumers benefit from the use of a VAD as it makes their daily lives more convenient, more comfortable, and simpler (Zierau et al., 2022). At the same time, companies can also benefit from interactions with VADs by collecting consumer-related data and storing it in large databases for marketing purposes (Guha et al., 2022; Rabassa et al., 2022).
