Determinants of Generative AI System Adoption and Usage Behavior in Korean Companies: Applying the UTAUT Model.

This study addresses the academic gap in the adoption of generative AI systems by investigating the factors influencing technology acceptance and usage behavior in Korean firms. Although recent advancements in AI are accelerating digital transformation and innovation, empirical research on the adoption of these systems remains scarce. To fill this gap, this study applies the Unified Theory of Acceptance and Use of Technology (UTAUT) model, surveying 300 employees from both large and small enterprises in South Korea.

A Study on the Characteristics of Sports Athletes' YouTube Channels and User Reactions.

This study examined the content characteristics and user responses of athlete-run sports YouTube channels, providing empirical insights for content production strategies and contributing to the development of athlete-run sports YouTube channels. Content analysis was conducted on 3306 videos posted on 20 popular YouTube channels of South Korean athletes from 1 January 2020 to 31 December 2021. The formal characteristics analyzed included video length, the presence of foreign language subtitles, paid advertisements, and information sources.

Comparison of Audience Behavior between eSports and Authentic Sports Fans.

This study analyzed how the behavioral patterns of esports and authentic sports viewers differ, adopting user and gratification theory and media transportation theory. In particular, it was investigated whether there was a difference in behavioral patterns according to the experience of playing the sport even among authentic sports viewers. As a result of analyzing the relationship between viewers' motivation and media transportation outcomes through structural equation modeling and multigroup structural equation modeling, it was observed that cognitive motivation was more important for esports viewers than for authentic sports viewers.

Athletic justice: Scale development and validation.

The current study aimed to create a reliable and valid scale to measure athletes' perception of fairness regarding coaches' behaviors. The study utilized a scale development process, including three steps: (a) item generation, (b) scale development, and (c) scale evaluation. Both quantitative and qualitative approaches were utilized to generate items and achieve content validity.

Impact of Met-Expectation of Athletic Justice on Athletic Satisfaction and Organizational Commitment via Leader-Member Exchange among Elite Saudi Arabian Athletes.

Athletes' perceptions of fairness toward coaching behaviors and decisions can play a crucial role in the development and maintenance of a strong coach-athlete relationship. However, scholars have given limited attention to athletes' perceptions of fairness. Therefore, the current study aimed to explore the relationship between coaches and athletes by applying the concept of organizational justice based on met-expectation theory.

Analyzing factors affecting risk aversion: Case of life insurance data in Korea.

This research employs machine learning analysis on extensive data from a prominent Korean life insurance company to substantiate the insurance demand theory, which posits that insurance demand increases with risk aversion. We quantitatively delineate the traits of risk-averse individuals. Our study focuses on a cohort of 94,306 individuals who have filed insurance claims due to illness.

Self-Serving Bias in Performance Goal Achievement Appraisals: Evidence From Long-Distance Runners.

While working with a long-distance running event organizer, the authors of this study observed considerable differences between event participants' official finish time (i.e., bib time) and their self-reported finish time in the post-event survey.

Patterns of Weight Change in a Commercial Weight Loss Program.

In this study, we examined compliance and progress factors associated with weight loss and maintenance, individual patterns of weight trends following weight loss, and impact of early weight loss on longer-term weight change. We conducted secondary analysis of pre-post data. Participants were 8769 persons (mean age = 47.

Post annealing effects on the electrical characteristics of pentacene thin film transistors on flexible substrates.

This work studies the effect of post annealing of pentacene on a flexible substrate through the examination of electrical properties and surface morphologies. It is confirmed that the best performance of devices is achieved when the post annealing temperature is 60 degrees C, since the grain size increases, which decrease grain boundaries caused charge transport limit. We can also confirmed the large threshold voltage shift of device annealed at 60 degrees C that means the lower trap density between channel and insulator interface.

Low-voltage-driven pentacene thin-film transistors with cross-linked poly(4-vinylphenol)/high-k Bi55b3O15 hybrid dielectric for phototransistor.

This paper describes the fabrication of pentacene thin-film transistors (TFTs) with an organic/inorganic hybrid gate dielectric, consisting of cross-linked poly(4-vinylphenol) (PVP) and Bi5Nb3O15. A 300-nm-thick Bi5Nb3O15 dielectric film, grown at room temperature, exhibits a high dielectric constant (high-k) value of 40 but has an undesirable interface with organic semiconductors (OSC). To form better interfaces with OSC, a cross-linked PVP dielectric was stacked on the Bi5Nb3O15 dielectric.

Organic thin film transistor with poly(4-vinylbiphenyl) blended 6,13-bis(triisopropylsilylethynyl)pentacene on propyleneglycolmonomethyletheracetate dielectric surface.

This paper presents the latest results in the use of soluble materials, such as organic semiconductors (OSCs) and gate-dielectrics, for simplified processing of organic thin film transistors (OTFTs). In this work, the fabrication of a solution-processed OTFT, with 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) and TIPS-pentacene mixed with poly(4-vinylbiphenyl) (PVBP) as the OSC, and propyleneglycolmonomethyletheracetate (PGMEA) as the gate-dielectric, is described. From electrical measurements, we observed exemplary I-V characteristics for these TFTs.
