Effect of in-game situations and advertisement animation in eSports on visual attention, memory, brand attitude and behavioral intentions The research team led by Professor Daehwan Kim in the Department of Marine Sports has published significant findings on the effectiveness of advertising in eSports, garnering attention from both academia and industry. The research team analyzed the impact of in-game situations and advertisement animation on visual attention, memory, brand attitude, and behavioral intention in their latest study, providing empirical validation for advertising strategies in eSports. This study aimed to examine how different advertising exposure methods during eSports matches influence audience visual attention and memory formation which sequentially affect brand attitudes and behavioral intentions. The research team conducted experiments in which participants watched a manipulated video of a StarCraft eSports match, containing both static and animated advertisements displayed during battle and non-battle situations. Participants, equipped with eye-tracking devices, observed the 2-minute-and-30-second video and subsequently completed a questionnaire measuring visual attention, memory retention, brand attitude, and behavioral intention. The findings revealed that advertisements received significantly higher visual attention―both in terms of fixation count and duration―during non-battle situations than in battle situations. Additionally, increased fixation count on advertisements led to enhanced implicit memory, which in turn positively influenced brand attitude and behavioral intention. However, differences in advertisement animation (static vs. animated) had no substantial impact on visual attention or memory formation. This study offers valuable insights for developing effective eSports advertising strategies. The research team emphasized that "eSports advertisements are more effective when placed in non-battle situations rather than during intense gameplay. Additionally, repeated exposure to brand advertisements is crucial in enhancing brand recognition." They further noted that "natural and unobtrusive advertisement exposure plays a key role in stimulating implicit memory, which ultimately shapes brand attitudes and behavioral intentions positively.“ The study has been published in the international academic journal [Internet Research](IF 5.9), marking a significant contribution to the field of eSports advertising. It not only advances academic understanding of advertising effectiveness in digital sports but also highlights Pukyong National University’s leading role in eSports and digital marketing research. The research findings are expected to serve as a foundational framework for optimizing advertising strategies in the rapidly growing eSports industry, providing new directions for both academia and industry professionals.

Professor Nam Seung Yun, along with Professor Park Sang-Hyug from the same department and Professor Yoon Changhan from the Department of Biomedical Engineering at Inje University, successfully developed the world’s first technology that precisely measures the elasticity changes of cell scaffolds in real-time during the bioprinting process using ultrasonic shear wave elastography. Bioprinting is an advanced technology for tissue regeneration and artificial organ development, but there have been limitations in precisely evaluating the mechanical properties of cell scaffolds in real time. Human tissues have varying elastic properties, and since the growth and differentiation of cells are greatly influenced by these mechanical characteristics, the development of a technology to dynamically monitor them is essential. Conventional methods can only assess the mechanical properties destructively before and after the fabrication of the cell scaffold, making it difficult to capture dynamic changes during the bioprinting process. However, the technology developed by the research team has the advantage of enabling non-destructive monitoring of the elasticity and stability of the structure even during the fabrication of the cell scaffolds. The research team published their findings in the paper titled “Suspended bioprinting with in-situ elasticity monitoring using the assessment of shear wave phase velocity” in the top-tier international journal

Professor Se-Jung Lee's Team at Pukyong National University Developed Metformin-Based Treatment for ColitisPukyong National University (President Sang-Hoon Bae) announced that the research team led by Professor Se-Jung Lee from the Department of Smart Healthcare Convergence, Human Bio-Convergence Major, has developed an innovative metformin capsule effective in treating inflammatory bowel disease (IBD) and improving the gut microbiome. Professor Se-Jung Lee collaborated with Professor Chang-Hyung Choi from Yeungnam University, and the joint research findings were published in January in the international journal Journal of Controlled Release (IF 10.5), which specializes in chemistry and pharmacology. The research team developed an oral pH-responsive drug delivery system using microfluidic technology to encapsulate metformin, a well-known diabetes treatment, within a triple-layer hydrogel capsule. This capsule is designed to release metformin specifically in the colonic inflammation site (pH 7) while protecting the drug from degradation in the acidic gastric environment (pH 2). This approach significantly enhances the bioavailability of the drug at the target site, enabling effective treatment of inflammatory bowel disease (IBD) with lower doses. The study also revealed that metformin not only regulates the pro-inflammatory immune response mechanism in IBD animal models but also improves the diversity and richness of the gut microbiota. Professor Se-Jung Lee explained, “Patients with inflammatory colitis often face dietary restrictions, which can impair nutrient absorption, disrupt glycemic control, and increase the risk of developing Type 2 diabetes. While metformin has garnered significant attention as an exceptional diabetes treatment, its potential as a colitis treatment remains largely unexplored. Moreover, its stability and bioavailability are often compromised due to degradation by gastric acid and digestive enzymes before reaching the intestinal tract, necessitating higher doses. This encapsulation technology addresses these limitations and represents a breakthrough in drug delivery.” He further emphasized, “Our findings highlight metformin’s novel pharmacological effects and its potential as a therapeutic option for microbiome modulation and the treatment of refractory colitis through microcapsulation technology.” Additionally, Professor Lee shared his aspirations, stating, “Through the development of advanced microcapsules and microneedles, I aim to discover biopharmaceuticals, such as stem cells, peptides, and antibodies, capable of being specifically delivered to disease sites. This research will contribute to treating metabolic, chronic, and intractable diseases. I also hope to foster the next generation of talent in the field of smart healthcare.”
대외협력과 (2025-01-21)COUNT 183Pukyong National University Research Team Discovers Anion Separation Phenomenon in All-Solid-State Batteries-Research by Professor Jeong Seong-cheol’s Team Published in the UK Royal Society of Chemistry Journal-Localized Anion Separation Phenomenon Causes High Ionic Conductivity Pukyong National University (President Bae Sang-hoon) announced that Professor Jeong Seong-cheol’s (Department of Physics) research team discovered a phenomenon in which monovalent and divalent ions are locally separated in the Li6PS5Cl solid electrolyte of the argyrodite structure used in all-solid-state batteries. The research team, led by Professor Jeong Seong-cheol, Postdoctoral Researcher Lee Se-ho (G-LAMP Project), and Ph.D. student Jeon Tae-gon (Department of Physics), revealed through first-principles calculations that the difference in lithium mobility due to the anion domain caused by the anion local separation discovered in the Li6-xPS5-xClBrx solid electrolyte is the cause of the high ion conductivity in the Li6PS5Cl series solid electrolytes. Solid electrolytes based on the argyrodite structure have excellent ion conductivity, good cost-effectiveness of raw materials, and ease of synthesis, leading to active research in this field. Professor Jung’s team found that in this study, lithium ions are more concentrated in the S2- divalent anion region than in the Cl- and Br- monovalent anion regions, leading to the effective stabilization of the argyrodite structure. Additionally, lithium ions in the divalent anion region showed low mobility due to their strong binding with the anions, while lithium ions in the monovalent anion region exhibited higher mobility due to weaker binding with the anions. Through this, they identified that the lithium diffusion mechanism in argyrodite solid electrolytes relies on the anion regions. Professor Jung Seong-cheol stated, “This study reveals that the well-known disordered arrangement of anions in Li6PS5Cl-based argyrodite solid electrolytes is actually related to the local separation of anions, providing a new perspective for understanding the high conductivity of argyrodite solid electrolytes.” Meanwhile, this research was conducted with support from the Ministry of Education’s G-LAMP project and was recently published in the prestigious international journal
