Background: The external rotation (ER) exercise in performed at a 90° abduction of the shoulder joint is an effective to strengthen the infraspinatus. However, failure of the humeral head to control axial rotation during exercise can be increased the posterior deltoid over activity. Biofeedback training is an effective method of promoting motor learning and control it could look forward to activate the infraspinatus selectively by controlling the humeral head during exercise. Objects: The aim of this study was investigated that whether biofeedback for axial rotation was effective to activate selectively the infraspinatus during ER exercise. Methods: The 15 healthy males participated, and all subjects performed both ER exercise in a sitting position with shoulder abducted 90° under conditions with and without axial rotation biofeedback. Exercise was performed in a range of 90° ER, divided into three phases: concentric, isometric, and eccentric. The infraspinatus and posterior deltoid muscle activity were observed using surface electromyography. Results: Both infraspinatus activity (p < 0.01) and infraspinatus to posterior deltoid activity ratio (p = 0.01) were significantly higher with biofeedback however, posterior deltoid activity was significantly lower with biofeedback (p = 0.01). The infraspinatus muscle activity and muscle activity ratio were the highest in the isometric contraction type, and there were significant differences for all contraction types (p < 0.05). Whereas, the posterior deltoid activity was the lowest in the isometric contraction type, and showed a significant difference between isometric and other two contraction types (p < 0.05), but no significant different between concentric and eccentric contraction. Conclusion: Our results indicate that the axial rotation biofeedback during sitting ER exercise might be effective method to activating selective infraspinatus muscle and recommended to enhance the dynamic stability of the shoulder joint.

This descriptive correlational study describes the relationship between collaboration among health care professions and nurses’ organizational commitment in the operating room. A cross sectional survey of nurses (N = 142) was conducted in March 2020. The participants were nurses with more than one year work experience in operating rooms at three university hospitals in Seoul and Gyeonggi-do. Collaboration among nurses was measured using the Nurse–Nurse Collaboration Scale, while collaboration between nurses and physicians was measured by the Nurse-Physician Collaboration Scale (NPCS). All analyses were conducted using the IBM SPSS Statistics, version 23.0 with independent t-test, one-way ANOVA, Scheffé test, Pearson's Correlation, and multiple regression. The results were as follows : The collaboration among operating room nurses was scored with an average of 2.87 out of a total of 4. Collaboration between operating room nurses to physician scored 3.47 average out of 5 total. Organizational commitment scored 3.24 average out of 5 total. The factors influencing the organizational commitment of nurses in operating rooms include collaboration among nurses and effective communication, as well as collaboration between nurses and physicians for decision-making regarding treatment and nursing care. The explanatory amount of general characteristic, nurse-physician collaboration, and nurse-nurse collaboration variables was 33%, 15%, 13% respectively. Based on these findings, to enhance collaboration among operating room nurses, there is a significant need for systematic education on communication skills and decision-making competencies, continuous research, and organizational efforts.

This study aimed to predict the shelf life of black soybean Sunsik to develop a functional labeling system for the product. The Arrhenius equation was used to calculate the shelf life by examining alterations in the dietary fiber and calcium levels of black soybean Sunsik stored at 25, 35, and 50°C for 0, 6, and 12 months. Dietary fiber and calcium analyses were performed according to the experimental methods specified in the Food Code of the Ministry of Food and Drug Safety. Both black soybean Sunsik (BS) and black soybean Sunsik containing nondigestible maltodextrin and calcium lactate (BSN) exhibited an upward trend in dietary fiber content after 12 months of storage, compared to their initial levels. During storage, the phytate in Sunsik degraded, releasing cations that facilitated the formation of new cross-links between pectic acid and middle lamella, which ultimately increased dietary fiber content. Conversely, the calcium contents of both BS and BSN decreased with prolonged storage. Based on these findings, the expected shelf life of BS and BSN was calculated as 15.65 and 28.34 months, respectively.

This study investigated which factors impact esports viewership for League of Legends matches through Live and highLight streaming video. This research anaLyzed League of Legends viewership factors' differences between the three Leagues (LCK, LCS, and LEC) where viewership factors infLuence esports viewership demand through LOL’s Live and highLight streaming video. League of Legends not onLy has the highest audience among different various esports, aLso has formed a huge market from diverse countries. In order to soLve each League's unbaLance viewership trend issue between the three Leagues, and facing worLdwide viewership decrease, this study examined viewership impact factors from three Leagues with the highest viewership ratings: Korea's LCK, North America's LCS, and Europe's LEC. After that, differences in viewership impact factors for the research were anaLyzed and compared to each League. SpecificaLLy, this study investigated which factors impact esports viewership for League of Legends (LOL) matches. Data (N=1581) of reguLar season matches from the LCK, LCS, and LEC Leagues (2020 spring to 2021 summer) were coLLected and anaLyzed. This study anaLyzed the average number of visitors per minute of Twitch Live streaming and the number of views on YouTube highLights. Five main viewership factors(the uncertainty of match, consumer preferences, match importance, team attributes, match content, and controL variabLes), and seventeen independent variabLes were verified by muLtipLe regression anaLysis using STATA 15. As a resuLt of the anaLysis, the modeL with the number of reaL-time audience as the dependent variabLe demonstrated different trends between Leagues in terms of the uncertainty of match factors (rank difference, win rate difference, goLd difference, kiLL difference, object difference), and consumer preference factors(fan, operating period of both teams, number of worLd championship wins, the number of championship semifinaL advances). WhiLe the match importance factors(week, top-rank matches) and match content factors (the sum of kiLLs, the sum of assists, the sum of objects) indicated somewhat simiLar tendencies between Leagues. In the modeL with the number of highLights views as the dependent variabLe, consumer preference factors and match importance factors tended to be somewhat simiLar, but match content factors prone to be sLightLy different between Leagues. In addition, the uncertainty of the match factors did not show a significant infLuence across the three Leagues. Findings from this research expand and appLy the variabLes derived from the demand determination theory of traditionaL sports to e-sports demand research. This study heLps stakehoLders understand various esports cuLtures from different regions. Furthermore, it is meaningfuL in that it provides information that wiLL contribute to the growth of the entire League of Legends market through baLanced deveLopment between Leagues.

The integration of Live streaming and E-commerce, also known as Live commerce, has been widely used in Asia. The live commerce market in China, which leads the live commerce business, reached 2.36 trillion yuan (about 340 billion dollars) at the end of 2021. While revenue is an important indicator for a company, customer engagement in live commerce, which can acquire potential customers through brand loyalty formation, community building, and information sharing, is also a crucial indicator in consideration of long-term development.

Crowding is widely observed in various tourism contexts. Compared with natural scenic areas, theme parks have concrete boundaries and are physically, economically, or culturally separate from the surrounding area, it also brings problems with carrying capacity and visitor management. Data shows that China has become a critical theme park market, and crowding has become a major problem for theme park operators in China. This study examined the effects of human crowding on visitors' emotions, satisfaction, and behavioral intentions using the M-R model as a framework. The investigations were conducted in Shanghai Disneyland and Zhuhai Chimelong Ocean Kingdom, 295 and 410 valid questionnaires were collected respectively.

Artificial intelligence (AI) is producing more and more branded content such as image, text, video and sound. This area of so-called generative AI became particularly popular with the public after the launch of ChatGPT. Furthermore, political correctness has been discussed in recent years, since society is becoming increasingly sensitive to certain issues surrounding topics such as racism or gender equality. Therefore, it is more important than ever for brands to communicate in a politically correct way. In the past, humans were responsible for negative brand communication and brand voice. However, with the development of these AI-tools and platforms, AI also creates brand voice and this AI-generated brand voice can similarly cause such negative feelings.

To promote the diffusion of environmentally friendly equipment, appropriate measures need to be taken for each target group.

Genderless fashion is a trend that involves clothing and accessories designed for anyone, regardless of gender identity, and may blur traditional gender boundaries by incorporating elements associated with men's or women's clothing. The trend is driven by changing attitudes towards gender, increasing awareness and acceptance of gender fluidity and non-binary identities, and a desire for more inclusive ways of expressing gender through fashion. Empirical evidence on how genderless or gender-neutral marketing efforts affect consumer response is limited. Our experimental study contributes to this literature by analyzing the role of clothing gender labels and consumer gender on purchase intention of clothing.

Customer engagement has been a focus of a significant amount of research. Most of the prior research on customer engagement typically focused on engagement and loyalty in loyalty program context, while the impact of rewarded customer engagement on program members has largely been missed out. Additionally, no prior study yet has focused on the conceptualization of rewarded customer engagement, while exploring and comparing its significance on various digital platforms, such as loyalty programs and Metaverse. Thus, this study aims to conceptualize rewarded customer engagement while investigating its impact on loyalty program members, and whether it induces and/or encourages their engagement in brand’s Metaverse platform(s).

Livestreaming commerce is a form of e-commerce that embedded real-time video presentation and social interaction. It provides immersive shopping experience reinforced by high levels of interactivity and instant bidirectional communication. China, as one of the biggest livestreaming markets, has reached 2.3 trillion (CNY) livestreaming commerce market value in 2022. In a 2020 survey, two-thirds of Chinese consumers experienced livestreaming shopping in the previous year. Accordingly, luxury brands, such as Chanel and Louis Vuitton have started to implement livestreaming commerce in China. However, for years, luxury brands have struggled with online commerce as it may impact upon perceptions of exclusivity and dilute brand value. Research on the efficacy of live commerce emerged in recent years and mostly focused on non-luxury brands. However, luxury brands cannot simply copy digital marketing strategies that proved to be effective for non-luxury brands. To date, limited academic attention has been devoted to the luxury commerce in a livestreaming context.
