< Professor Se Kwon Kim of the Department of Physics (left), Dr. Zarzuela of the University of Mainz, Germany (right) > What if the magnon Hall effect, which processes information using magnons (spin waves) capable of current-free information transfer with magnets, could overcome its current limitation of being possible only on a 2D plane? If magnons could be utilized in 3D space, they would enable flexible design, including 3D circuits, and be applicable in various fields such as next-generation neuromorphic (brain-mimicking) computing structures, similar to human brain information processing. KAIST and an international joint research team have, for the first time in the world, predicted a 3D magnon Hall effect, demonstrating that magnons can move freely and complexly in 3D space, transcending the conventional concept of magnons. KAIST (President Kwang Hyung Lee) announced on May 22nd that Professor Se Kwon Kim of the Department of Physics, in collaboration with Dr. Ricardo Zarzuela of the University of Mainz, Germany, has revealed that the interaction between magnons (spin waves) and solitons (spin vortices) within complex magnetic structures (topologically textured frustrated magnets) is not simple, but complex in a way that enables novel functionalities. Magnons (spin waves), which can transmit information like electron movement, are garnering attention as a next-generation information processing technology that transmits information without using current, thus generating no heat. Until now, magnon research has focused on simple magnets where spins are neatly aligned in one direction, and the mathematics describing this was a relatively simple 'Abelian gauge theory.' The research team demonstrated, for the first time in the world, that in complex spin structures like frustrated magnets, magnons interact and become entangled in complex ways from various directions. They applied an advanced mathematical framework, 'non-Abelian gauge theory,' to describe this movement, which is a groundbreaking achievement. This research presents the possibility of future applications in low-power logic devices using magnons and topology-based quantum information processing technologies, indicating a potential paradigm shift in future information technology. In conventional linear magnetic materials, the value representing the magnetic state (order parameter) is given as a vector. In magnonics research based on this, it has been interpreted that a U(1) Abelian gauge field is induced when magnons move in soliton structures like skyrmions. This means that the interaction between solitons and magnons has a structure similar to quantum electrodynamics (QED), which has successfully explained various experimental results such as the magnon Hall effect in 2D magnets. < Figure. Schematic diagram of non-Abelian magnon quantum chromodynamics describing the dynamics of three types of magnons discovered for the first time in this study.> However, through this research, the team theoretically revealed that in frustrated magnets, the order parameter must be expressed not as a simple vector but as a quaternion. As a result, the gauge field experienced by magnons resembles an SU(3) non-Abelian gauge field, rather than a simple U(1) Abelian gauge field. This implies that within frustrated magnets, there are not one or two types of magnons seen in conventional magnets, but three distinct types of magnons, each interacting and intricately entangled with solitons. This structure is highly significant as it resembles quantum chromodynamics (QCD) that describes the strong interaction between quarks mediated by gluons rather than quantum electrodynamics (QED) that describes electromagnetic forces. Professor Se Kwon Kim stated, "This research presents a powerful theoretical framework to explain the dynamics of magnons occurring within the complex order of frustrated magnets," adding, "By pioneering non-Abelian magnonics, it will be a conceptual turning point that can influence quantum magnetism research as a whole." The research results, with Dr. Ricardo Zarzuela of the University of Mainz, Germany, as the first author, were published in the world-renowned physics journal Physical Review Letters on May 6th.※ Paper title: "Non-Abelian Gauge Theory for Magnons in Topologically Textured Frustrated Magnets," Phys.

But now, thanks to a new AI-powered app developed by researchers at KAIST in collaboration with NAVER AI Lab and Dodakim Child Development Center, parents are finally experiencing moments of genuine connection with their children. On the 16th, the KAIST (President Kwang Hyung Lee) research team, led by Professor Hwajung Hong of the Department of Industrial Design, announced the development of ‘AAcessTalk,’ an artificial intelligence (AI)-based communication tool that enables genuine communication between children with autism and their parents. This research was recognized for its human-centered AI approach and received international attention, earning the Best Paper Award at the ACM CHI 2025*, an international conference held in Yokohama, Japan.*ACM CHI (ACM Conference on Human Factors in Computing Systems) 2025: One of the world's most prestigious academic conference in the field of Human-Computer Interaction (HCI).  This year, approximately 1,200 papers were selected out of about 5,000 submissions, with the Best Paper Award given to only the top 1%. The conference, which drew over 5,000 researchers, was the largest in its history, reflecting the growing interest in ‘Human-AI Interaction.’ Called AACessTalk, the app offers personalized vocabulary cards tailored to each child’s interests and context, while guiding parents through conversations with customized prompts. This creates a space where children’s voices can finally be heard—and where parents and children can connect on a deeper level. Traditional augmentative and alternative communication (AAC) tools have relied heavily on fixed card systems that often fail to capture the subtle emotions and shifting interests of children with autism. AACessTalk breaks new ground by integrating AI technology that adapts in real time to the child’s mood and environment. < Figure. Schematics of AACessTalk system. It provides personalized vocabulary cards for children with autism and context-based conversation guides for parents to focus on practical communication. Large ‘Turn Pass Button’ is placed at the child’s side to allow the child to lead the conversation. > Among its standout features is a large ‘Turn Pass Button’ that gives children control over when to start or end conversations—allowing them to lead with agency. Another feature, the “What about Mom/Dad?” button, encourages children to ask about their parents’ thoughts, fostering mutual engagement in dialogue, something many children had never done before. One parent shared, “For the first time, we shared a meaningful exchange.” Such stories were common among the 11 families who participated in a two-week pilot study, where children used the app to take more initiative in conversations and parents discovered new layers of their children’s language abilities. Parents also reported moments of surprise and joy when their children used unexpected words or took the lead in conversations, breaking free from repetitive patterns. “I was amazed when my child used a word I hadn’t heard before. It helped me understand them in a whole new way,” recalled one caregiver. Professor Hwajung Hong, who led the research at KAIST’s Department of Industrial Design, emphasized the importance of empowering children to express their own voices. “This study shows that AI can be more than a communication aid—it can be a bridge to genuine connection and understanding within families,” she said.  Looking ahead, the team plans to refine and expand human-centered AI technologies that honor neurodiversity, with a focus on bringing practical solutions to socially vulnerable groups and enriching user experiences. This research is the result of KAIST Department of Industrial Design doctoral student Dasom Choi's internship at NAVER AI Lab.* Thesis Title: AACessTalk: Fostering Communication between Minimally Verbal Autistic Children and Parents with Contextual Guidance and Card Recommendation* DOI: 10.1145/3706598.3713792* Main Author Information: Dasom Choi (KAIST, NAVER AI Lab, First Author), SoHyun Park (NAVER AI Lab) , Kyungah Lee (Dodakim Child Development Center), Hwajung Hong (KAIST), and Young-Ho Kim (NAVER AI Lab, Corresponding Author) This research was supported by the NAVER AI Lab internship program and grants from the National Research Foundation of Korea: the Doctoral Student Research Encouragement Grant (NRF-2024S1A5B5A19043580) and the Mid-Career Researcher Support Program for the Development of a Generative AI-Based Augmentative and Alternative Communication System for Autism Spectrum Disorder (RS-2024-00458557).

Fear memories can form in the brain following exposure to threatening situations such as natural disasters, accidents, or violence. When these memories become excessive or distorted, they can lead to severe mental health disorders, including post-traumatic stress disorder (PTSD), anxiety disorders, and depression. However, the mechanisms underlying fear memory formation triggered by affective pain rather than direct physical pain have remained largely unexplored – until now. A KAIST research team has identified, for the first time, a brain circuit specifically responsible for forming fear memories in the absence of physical pain, marking a significant advance in understanding how psychological distress is processed and drives fear memory formation in the brain. This discovery opens the door to the development of targeted treatments for trauma-related conditions by addressing the underlying neural pathways.  < Photo 1. (from left) Professor Jin-Hee Han, Dr. Junho Han and Ph.D. Candidate Boin Suh of the Department of Biological Sciences > KAIST (President Kwang-Hyung Lee) announced on May 15th that the research team led by Professor Jin-Hee Han in the Department of Biological Sciences has identified the pIC-PBN circuit*, a key neural pathway involved in forming fear memories triggered by psychological threats in the absence of sensory pain. This groundbreaking work was conducted through experiments with mice.*pIC–PBN circuit: A newly identified descending neural pathway from the posterior insular cortex (pIC) to the parabrachial nucleus (PBN), specialized for transmitting psychological threat information. Traditionally, the lateral parabrachial nucleus (PBN) has been recognized as a critical part of the ascending pain pathway, receiving pain signals from the spinal cord. However, this study reveals a previously unknown role for the PBN in processing fear induced by non-painful psychological stimuli, fundamentally changing our understanding of its function in the brain. This work is considered the first experimental evidence that 'emotional distress' and 'physical pain' are processed through different neural circuits to form fear memories, making it a significant contribution to the field of neuroscience. It clearly demonstrates the existence of a dedicated pathway (pIC-PBN) for transmitting emotional distress. The study's first author, Dr. Junho Han, shared the personal motivation behind this research: “Our dog, Lego, is afraid of motorcycles. He never actually crashed into one, but ever since having a traumatizing event of having a motorbike almost run into him, just hearing the sound now triggers a fearful response. Humans react similarly – even if you didn’t have a personal experience of being involved in an accident, a near-miss or exposure to alarming media can create lasting fear memories, which may eventually lead to PTSD.” He continued, “Until now, fear memory research has mainly relied on experimental models involving physical pain. However, much of real-world human fears arise from psychological threats, rather than from direct physical harm. Despite this, little was known about the brain circuits responsible for processing these psychological threats that can drive fear memory formation.” To investigate this, the research team developed a novel fear conditioning model that utilizes visual threat stimuli instead of electrical shocks. In this model, mice were exposed to a rapidly expanding visual disk on a ceiling screen, simulating the threat of an approaching predator. This approach allowed the team to demonstrate that fear memories can form in response to a non-nociceptive, psychological threat alone, without the need for physical pain.   < Figure 1. Artificial activation of the posterior insular cortex (pIC) to lateral parabrachial nucleus (PBN) neural circuit induces anxiety-like behaviors and fear memory formation in mice. > Using advanced chemogenetic and optogenetic techniques, the team precisely controlled neuronal activity, revealing that the lateral parabrachial nucleus (PBN) is essential to form fear memories in response to visual threats. They further traced the origin of these signals to the posterior insular cortex (pIC), a region known to process negative emotions and pain, confirming a direct connection between the two areas. The study also showed that inhibiting the pIC–PBN circuit significantly reduced fear memory formation in response to visual threats, without affecting innate fear responses or physical pain-based learning. Conversely, artificially activating this circuit alone was sufficient to drive fear memory formation, confirming its role as a key pathway for processing psychological threat information. < Figure 2. Schematic diagram of brain neural circuits transmitting emotional & physical pain threat signals. Visual threat stimuli do not involve physical pain but can create an anxious state and form fear memory through the affective pain signaling pathway. > Professor Jin-Hee Han commented, “This study lays an important foundation for understanding how emotional distress-based mental disorders, such as PTSD, panic disorder, and anxiety disorder, develop, and opens new possibilities for targeted treatment approaches.” The findings, authored by Dr. Junho Han (first author), Ph.D. candidate Boin Suh (second author), and Dr. Jin-Hee Han (corresponding author) of the Department of Biological Sciences, were published online in the international journal Science Advances on May 9, 2025.※ Paper Title: A top-down insular cortex circuit crucial for non-nociceptive fear learning.

Even after the COVID-19 pandemic, various new infectious diseases continue to emerge, posing ongoing viral threats that demand robust and sustained immune defenses. However, excessive immune reactions can also harm body tissues, causing significant health issues. KAIST and an international research team have discovered a critical protein that acts as a 'switch' regulating immune responses to viruses. This breakthrough is expected to lay the groundwork for future infectious disease responses and autoimmune disease treatment strategies. KAIST (President Kwang-Hyung Lee) announced on May 14 that a joint research team led by Professor Yoosik Kim from the Department of Chemical and Biomolecular Engineering at KAIST and Professor Seunghee Cha from University of Florida has discovered the mechanism by which double-stranded RNA derived from mitochondria amplifies immune responses. They identified the protein SLIRP as an 'immune switch' that regulates this process, playing a crucial role in both viral infections and autoimmune diseases. < (From left) Master's candidate Yewon Yang, Professor Yoosik Kim and Ph.D. candidate Doyeong Ku of the Department of Chemical and Biomolecular Engineering > Autoimmune diseases arise when the immune system fails to differentiate between external pathogens and the body's own molecules, leading to self-directed attacks. Despite extensive research, the precise causes of excessive inflammatory conditions like Sjögren’s syndrome and systemic lupus erythematosus remain unclear, and effective treatments are still limited. To uncover the molecular mechanisms driving immune hyperactivation and to identify potential regulatory factors, the research team led by Professor Yoosik Kim focused on mitochondrial double-stranded RNA (mt-dsRNA), a genetic immunogenic material produced within cellular organelles. Since mt-dsRNA structurally resembles viral RNA, it can mistakenly trigger immune responses even in the absence of an actual viral infection. The team discovered that SLIRP, a key regulator of mt-dsRNA, amplifies immune responses by stabilizing the RNA. They confirmed that SLIRP expression increases in experimental models simulating the tissues of autoimmune disease patients and viral infections. Conversely, suppressing SLIRP significantly reduced the immune response, underscoring its role as a critical factor in immune amplification. This study also demonstrated the dual function of SLIRP in different contexts. In cells infected with human beta coronavirus OC43 and encephalomyocarditis virus (EMCV), SLIRP suppression led to reduced antiviral responses and increased viral replication. Meanwhile, in the blood and salivary gland cells of Sjögren’s syndrome patients, where both SLIRP and mt-dsRNA levels were elevated, suppressing SLIRP alleviated the abnormal immune response. These findings highlight SLIRP as a key molecular switch that regulates immune responses in both infections and autoimmune diseases. < Figure 1. Schematic diagram of antiviral signal amplification by SLIRP: SLIRP-based mt-dsRNA induction, cytoplasmic accumulation, and strong interferon response induction by positive feedback of immune response activation. Confirmation of the immune regulatory function of SLIRP in defense against autoimmune diseases Sjögren's syndrome, coronavirus, and encephalomyocarditis virus infection. > Professor Yoosik Kim remarked, "Through this study, we have identified SLIRP as a crucial protein that drives immune amplification via mt-dsRNAs. Given its dual role in autoimmune diseases and viral infections, SLIRP presents a promising target for immune regulation therapies across various inflammatory disease contexts." The study, with Ph.D. student Do-Young Ku (first author) and M.S. student Ye-Won Yang (second author) from the Department of Chemical and Biomolecular Engineering at KAIST as primary contributors, was published online in the journal Cell Reports on April 19, 2025. ※ Paper title: SLIRP amplifies antiviral signaling via positive feedback regulation and contributes to autoimmune diseases※ Main authors: Do-Young Ku (KAIST, first author), Ye-Won Yang (KAIST, second author), Seunghee Cha (University of Florida, corresponding author), Yoosik Kim (KAIST, corresponding author) This study was supported by the Ministry of Health and Welfare's Public Health Technology Research Program and the National Institutes of Health (NIH) through Research Project (R01) funding.

Accurate pointing in virtual spaces is essential for seamless interaction. If pointing is not precise, selecting the desired object becomes challenging, breaking user immersion and reducing overall experience quality. KAIST researchers have developed a technology that offers a vivid, lifelike experience in virtual space, alongside a new tool that assists choreographers throughout the creative process. KAIST (President Kwang-Hyung Lee) announced on May 13th that a research team led by Professor Sang Ho Yoon of the Graduate School of Culture Technology, in collaboration with Professor Yang Zhang of the University of California, Los Angeles (UCLA), has developed the ‘T2IRay’ technology and the ‘ChoreoCraft’ platform, which enables choreographers to work more freely and creatively in virtual reality. These technologies received two Honorable Mention awards, recognizing the top 5% of papers, at CHI 2025*, the best international conference in the field of human-computer interaction, hosted by the Association for Computing Machinery (ACM) from April 25 to May 1. < (From left) PhD candidates Jina Kim and Kyungeun Jung along with Master's candidate, Hyunyoung Han and Professor Sang Ho Yoon of KAIST Graduate School of Culture Technology and Professor Yang Zhang (top) of UCLA > T2IRay: Enabling Virtual Input with Precision T2IRay introduces a novel input method that allows for precise object pointing in virtual environments by expanding traditional thumb-to-index gestures. This approach overcomes previous limitations, such as interruptions or reduced accuracy due to changes in hand position or orientation. The technology uses a local coordinate system based on finger relationships, ensuring continuous input even as hand positions shift. It accurately captures subtle thumb movements within this coordinate system, integrating natural head movements to allow fluid, intuitive control across a wide range. < Figure 1. T2IRay framework utilizing the delicate movements of the thumb and index fingers for AR/VR pointing > Professor Sang Ho Yoon explained, “T2IRay can significantly enhance the user experience in AR/VR by enabling smooth, stable control even when the user’s hands are in motion.” This study, led by first author Jina Kim, was supported by the Excellent New Researcher Support Project of the National Research Foundation of Korea under the Ministry of Science and ICT, as well as the University ICT Research Center (ITRC) Support Project of the Institute of Information and Communications Technology Planning and Evaluation (IITP). ▴ Paper title: T2IRay: Design of Thumb-to-Index Based Indirect Pointing for Continuous and Robust AR/VR Input▴ Paper link: https://doi.org/10.1145/3706598.3713442 ▴ T2IRay demo video: https://youtu.be/ElJlcJbkJPY ChoreoCraft: Creativity Support through VR for Choreographers In addition, Professor Yoon’s team developed ‘ChoreoCraft,’ a virtual reality tool designed to support choreographers by addressing the unique challenges they face, such as memorizing complex movements, overcoming creative blocks, and managing subjective feedback. ChoreoCraft reduces reliance on memory by allowing choreographers to save and refine movements directly within a VR space, using a motion-capture avatar for real-time interaction. It also enhances creativity by suggesting movements that naturally fit with prior choreography and musical elements. Furthermore, the system provides quantitative feedback by analyzing kinematic factors like motion stability and engagement, helping choreographers make data-driven creative decisions. < Figure 2. ChoreoCraft's approaches to encourage creative process > Professor Yoon noted, “ChoreoCraft is a tool designed to address the core challenges faced by choreographers, enhancing both creativity and efficiency. In user tests with professional choreographers, it received high marks for its ability to spark creative ideas and provide valuable quantitative feedback.” This research was conducted in collaboration with doctoral candidate Kyungeun Jung and master’s candidate Hyunyoung Han, alongside the Electronics and Telecommunications Research Institute (ETRI) and One Million Co., Ltd.

< (From the fifth from the left) Provost and Executive Vice President Gyun Min Lee, Auditor Eun Woo Lee, President Kwang-Hyung Lee, Dean of the School of Computing Seok-Young Ryu, former Krafton member and donor Woong-Hee Cho, Krafton Chairman Byung-Gyu Chang > KAIST announced on May 20th the completion of the expansion building for its School of Computing, the "KRAFTON Building." The project began in June 2021 with an ₩11 billion donation from KRAFTON and its employees, eventually growing to ₩11.7 billion with contributions from 204 donors. Designed as a "Pay It Forward" space, the building aims to enable alumni to pass on the gratitude they received from the school to their juniors and foster connection. Byung-Gyu Chang, Chairman of KRAFTON and a KAIST alumnus, expressed his joy, stating, "I am very pleased that the first building created by alumni donations within KAIST is now complete, and I hope it will continue to be a space for communication, challenges, and growth that connects to the next generation." The completion ceremony, held today at 3 PM in front of the KRAFTON SoC (School of Computing) Building at KAIST's main campus, was attended by over 100 people, including Chairman Byung-Gyu Chang, KAIST President Kwang-Hyung Lee, and Dean Seok-Young Ryu of the KAIST School of Computing. The building's inception dates back to June 2021, with an ₩11 billion donation from the gaming company KRAFTON and its current and former members, dedicated to nurturing future software talent at KAIST. Four alumni, including KRAFTON Chairman Byung-Gyu Chang, who graduated from the KAIST School of Computing, were the first to pledge donations. This initial act inspired more participants, leading to ₩5.5 billion in individual donations from a total of 11 people. KRAFTON Inc. then matched this amount, bringing the total donation to ₩11 billion. Since 2021, KRAFTON Inc. has operated a "Matching Grant" program, a donation culture initiative driven by its members. This system allows the company to match funds voluntarily raised by its employees, aiming to encourage active social participation and the creation of social value among its members. Following this, another 11 KAIST alumni from Devsisters Inc., famous for the Cookie Run series, joined the donation effort. This wave of generosity expanded to include a total of 204 participants, comprising graduates, alumni professors, and current students, acting as a catalyst for the spread of a donation culture within the campus. To date, approximately ₩11.7 billion has been raised for the expansion of the School of Computing building. Furthermore, small donations, including those from alumni and the general public, have continuously grown, reaching over 50,000 instances from 2021 to May 2025. The funds raised through donations were used to construct a 2,000-pyeong (approximately 6,600 square meters) building for individuals who, like Chairman Byung-Gyu Chang, will unleash their potential and become global leaders. The building was named "KRAFTON SoC (KRAFTON SoC)," and KRAFTON Inc. has further pledged additional donations for the building's maintenance over the next 10 years. The newly completed KRAFTON Building is a six-story structure. From the second floor up, it features research labs for 20 professors and graduate students to freely pursue their research, along with large lecture halls. The first floor is designed as a meeting place for current students, alumni, and seniors, serving as a space to remember those who came before them. The four lecture halls on the first floor are designated as "Immersion Camp Classrooms." During the summer and winter sessions, these rooms will be used for intensive month-long courses focused on improving coding and collaboration skills. During regular semesters, they will be utilized for other lectures. Additionally, to support the physical and mental well-being of those weary from study and research, the building includes a small café on the first floor, a fitness center on the second floor, a Pilates studio on the fifth floor, and a soundproof band practice room in the basement. Dean Seok-Young Ryu of the School of Computing explained, "The motivation for this wave of donations began with gratitude for the excellent professors and wonderful students, the free and open communication, the comfortable acceptance of diversity among various members, and the time when we could fearlessly dream. We cannot fully repay those who provided us with such precious time and space, but instead, this will be a 'Pay It Forward' space, a space of connection, where we share this gratitude with our juniors." Alumnus Byung-Gyu Chang shared, "KAIST is more than just an academic foundation for me; it's a meaningful place that helped me set the direction for my life. I am very happy that this space, born from the desire of KRAFTON's members and myself to give back the opportunities and learning we received to the next generation, is completed today. I hope this space becomes a small but warm echo for KAIST members who freely communicate, challenge themselves, and grow." < Congratulatory speech by alumnus Byung-Gyu Chang > President Kwang-Hyung Lee stated, "The KRAFTON SoC, the expanded building for the School of Computing, is not just a space; it is the culmination of the KAIST community spirit created by alumni, current students, and faculty. I sincerely thank everyone who participated in this meaningful donation, which demonstrates the power of sharing and connection." < Commemorative speech by President Kwang-Hyung Lee > On a related note, the KAIST Development Foundation is actively promoting the "TeamKAIST" campaign for the general public and KAIST alumni to meet more "Daddy Long-Legs" (benefactors) for KAIST.

A Gift of Life on Teachers' Day: Baby Geese Born at KAIST Pond On Teachers' Day, a meaningful miracle of life arrived at the KAIST campus. A pair of geese gave birth to two goslings by the duck pond. < On Teachers' Day, a pair of geese and their goslings leisurely swim in the pond. > The baby goslings, covered in yellow down, began exploring the pond's edge, scurrying about, while their aunt geese steadfastly stood by. Their curious glances, watchful gazes, playful hops on waterside rocks, and the procession of babies swimming behind their parents in the water melted the hearts of onlookers. < As night falls on the duck pond, the goose family gathers among the reeds. > This special new life, born on Teachers' Day, seems to symbolize the day's meaning of "care" and "growth." This wondrous scene of life brought warm comfort and joy to KAIST members, adding the inspiration of nature to a campus that is a space for research and learning. < Under the protection of the adult geese, the goslings take their first steps, exploring the pond's grassy areas and rocks. > This adorable family is already roaming the area leisurely, like the pond's owners. With the joy of life added to the spring-filled pond, warm smiles are spreading across the KAIST campus. < The geese look around, surveying their surroundings, while caring for their goslings. > The pond has now become a small but special haven for students and staff. This goose family, arriving on Teachers' Day, quietly reminds us of the meaning of care and learning conveyed by nature. < The goose family shows care and growth, and warm moments together are anticipated. > --- On Children's Day 2025, a Duck Becomes a Mother In July 2024, a special guest arrived at the KAIST campus. With soft yellow down, waddling gait, and a flat beak, it was undeniably a baby duck. However, for some reason, its mother was nowhere to be seen. Given that it wasn't afraid of people and followed them well, it was clear that someone had abandoned the duck. Fortunately, the baby duck was safely rescued thanks to prompt reporting by students. < Two ducks found on a corner of campus, immediately after their rescue in summer 2024. > The ducks, newly integrated into KAIST, seemed to adapt relatively peacefully to campus life. As new additions, they couldn't blend in with the existing goose flock that had settled on campus, but the geese didn't ostracize them either. Perhaps because they were awkward neighbors, there was hope that the ducks would soon join the existing goose flock. < Following their rescue based on a student's report in summer 2024, the ducks adapted to campus life under the protection of the campus facility team and Professor Won Do Heo. > Professor Won Do Heo of the Department of Biological Sciences, widely known as "Goose Dad," stepped forward to protect them along with the KAIST facility team. Professor Heo is well-known for consistently observing and protecting the campus geese and ducks, which are practically symbols of KAIST. Thanks to the care of the staff and Professor Heo, the two ducks were safely released back onto campus approximately one month after their rescue. < A moment on campus: Before winter, the ducks lived separately from the goose flock, maintaining a certain distance. While there were no conflicts, they rarely socialized. > However, as winter passed, sad news arrived. One duck went missing, and the remaining one was found injured by the pond. While the policy of the facility team and Professor Heo was to minimize intervention to allow campus animals to maintain their natural state, saving the injured duck was the top priority. After being isolated again for a month of recovery, the duck fully recovered and was able to greet spring under the sun. < The mother duck left alone in winter: One went missing, and the remaining one was found injured. After indoor isolation and recovery, she was released back onto campus in the spring. > As spring, the ducks' breeding season, began, Professor Heo decided to offer a little more help. When signs of egg-laying appeared, he consistently provided "special meals for pregnant mothers" throughout March. On the morning of May 5th, Children's Day, 28 days after the mother duck began incubating her eggs with the care and attention of KAIST members, new life finally hatched. It was a precious outcome achieved solely by the duck that had survived abandonment and injury, with no special protection other than food. The duck, having overcome hardship and injury to stand alone, has now formed a new family. Although there is still some distance from the existing goose flock, it is expected that they will naturally find their place in the campus ecosystem, as KAIST's geese are not aggressive or exclusive. The KAIST goose flock already has experience protecting and raising five ducklings. < A new beginning by the pond on Children's Day: On the morning of May 5th, the 28th day of incubation, four ducklings hatched by the pond. This was a natural hatching, achieved without protective equipment. > A single duck brought a special spring to the KAIST campus on Children's Day. The outcome achieved by that small life, leading to the birth of a new family, also symbolizes the harmonious coexistence of people and animals on the KAIST campus. The careful intervention of KAIST members, providing only the necessary assistance from rescue to hatching, makes us reconsider what "desirable coexistence between animals and people" truly means.

KAIST (President Kwang-Hyung Lee) announced on May 19th the opening of the solo exhibition, “Big Coins,” by photographer and media artist Hojun Ji (Adjunct Professor, Department of Industrial Design) at the SUPEX Hall in the Business School of the Seoul Campus. The exhibition will run from May 19th to the end of February of the following year. This exhibition at the KAIST Seoul Campus Business School presents artworks with an insightful perspective, inviting diverse interpretations from the audience. Notable pieces include ‘Priced,’ which juxtaposes Leonardo da Vinci's ‘Salvator Mundi,’ sold for approximately 450 million US dollars at a 2017 auction, with a Vatican coin bearing the image of Pope John XXIII. Another work, ‘Ciphered,’ superimposes a code used by the German army during World War II onto a Swiss coin featuring Helvetia. < Priced, 150x150cm, 2025 > Currently, Hojun Ji, an Adjunct Professor in KAIST’s Department of Industrial Design (and a student at the KAIST Graduate School of Culture Technology), creates his art using images captured by observing everyday objects through optical or electron microscopes. He has garnered particular attention for his unique artistic world, which combines enlarged microscopic photographs of coins from across the globe with significant news articles from modern and contemporary history. Yeo-sun Yoon, Dean of the College of Business Administration, commented, “While the KAIST Art Museum is located at the main campus in Daejeon, the College of Business Administration here on the Seoul Campus also regularly hosts exhibitions curated by the museum. I am delighted to encounter a new realm of art through this solo exhibition by Artist Hojun Ji.” < Ciphered, 150x150cm, 2025 > Hyeon-Jeong Suk, Director of the Art Museum and a Full Professor in KAIST’s Department of Industrial Design, remarked, “Professor Hojun Ji's experimental imagination is remarkably unique and eccentric. As a graduate student, he connected data from his observations of his lab dog’s droppings with Jeong Seon's <Geumgang Jeondo>. Such imaginative thinking exemplifies the direction KAIST is pursuing.” Artist Hojun Ji stated, “The coins I examined through optical and electron microscopes were not merely a form of payment but rather portraits of humanity etched with time and power. The history and memories embedded in their fine cracks and textures resonated with me as a singular sculpture. I aim to unlock the vast world of imagination concealed within these small pieces of metal.” < Geumgang Byeondo: a Variation of the View of Mt. Geumgang (a twist of Geumgang Jeondo - a Complete View of Geumgangsan Mountain, 1734), 80x120cm, 2009 > Ji has presented experimental works that transcend the boundaries of science and art through numerous exhibitions both domestically and internationally. His work has also been featured on the cover of the international academic journal Digital Creativity and is increasingly recognized for its artistic merit, with pieces housed in the Embassy of the Republic of Korea in Turkey, the Seoul Museum of Art, and the 9/11 Memorial Center in the United States. This solo exhibition, which will continue until the end of February of next year, is open to KAIST members and external visitors free of charge.

KAIST (President Kwang-Hyung Lee) announced on the 9th that it will hold a signboard ceremony for the establishment of the ‘AI Entertech Research Center’ with the artificial intelligence entertech company, Galaxy Corporation (CEO Yong-ho Choi) at the main campus of KAIST. < (Galaxy Corporation, from center to the left) CEO Yongho Choi, Director Hyunjung Kim and related persons / (KAIST, from center to the right) Professor SeungSeob Lee of the Department of Mechanical Engineering, Provost and Executive Vice President Gyun Min Lee, Dean Jung Kim of the Department of Mechanical Engineering and Professor Yong Jin Yoon of the same department > This collaboration is a part of KAIST’s art convergence research strategy and is an extension of its efforts to lead future K-Culture through the development of creative cultural content based on science and technology. Beyond simple technological development, KAIST has been continuously implementing the convergence model of ‘Tech-Art’ that expands the horizon of the content industry through the fusion of emotional technology and cultural imagination. Previously, KAIST established the ‘Sumi Jo Performing Arts Research Center’ in collaboration with world-renowned soprano Sumi Jo, a visiting professor, and has been leading the convergence research of art and engineering, such as AI-based interactive performance technology and immersive content. The establishment of the ‘AI Entertech Research Center’ this time is being evaluated as a new challenge for the technological expansion of the K-content industry. In addition, the role of singer G-Dragon (real name Kwon Ji-yong), an artist affiliated with Galaxy Corporation and a visiting professor in the Department of Mechanical Engineering at KAIST, was also a major factor. Since being appointed to KAIST last year, Professor Kwon has been actively promoting the establishment of a research center and soliciting KAIST research projects through his agency to develop the ‘AI Entertech’ field, which fuses entertainment and cutting-edge technology. < (Galaxy Corporation, from center to the left) CEO Yongho Choi, Director Hyunjung Kim and related persons / (KAIST, from center to the right) Professor SeungSeob Lee of the Department of Mechanical Engineering, Provost and Executive Vice President Gyun Min Lee, Dean Jung Kim of the Department of Mechanical Engineering and Professor Yong Jin Yoon of the same department > The AI Entertech Research Center is scheduled to officially launch in the third quarter of this year, and this inauguration ceremony was held in line with Professor Kwon Ji-yong’s schedule to visit KAIST. Galaxy Corporation recently had a private meeting with Microsoft (MS) CEO Nadella as the only entertech company, and is actively promoting the globalization of AI entertech. In addition, since last year, it has established a cooperative relationship with KAIST and plans to actively seek the convergence of entertech and technology that transcends time and space through the establishment of a research center. Professor Kwon Ji-yong will attend the ‘Innovate Korea 2025’ event co-hosted by KAIST, Herald Media Group, and the National Research Council of Science and Technology, held at the KAIST Lyu Keun-Chul Sports Complex in the afternoon of the same day, and will give a special talk on the topic of ‘The Future of AI Entertech.’ In addition to Professor Kwon, Professor SeungSeob Lee of the Department of Mechanical Engineering at KAIST, Professor Sang-gyun Kim of Kyunghee University, and CEO Yong-ho Choi of Galaxy Corporation will also participate in this talk show. The two organizations signed an MOU last year to jointly research science and technology for the global spread of K-pop, and the establishment of this research center is the first tangible result of this. Once the research center is fully operational, various projects such as the development of an AI-based entertech platform and joint research on global content technology will be promoted. < A photo of Professor Kwon Ji-yong (right) from at the talk show with KAIST President Kwang-Hyung Lee (left) from the previous year > Yong-ho Choi, Galaxy Corporation CHO (Chief Happiness Officer), said, “This collaboration is the starting point for providing a completely new entertainment experience to fans around the world by grafting KAIST AI and cutting-edge technologies onto the fandom platform,” and added, “The convergence of AI and entertech is not just technological advancement; it is a driving force for innovation that enriches human life.” Kwang-Hyung Lee, KAIST President, said, “I am confident that KAIST’s scientific and technological capabilities, combined with Professor Kwon Ji-yong’s global sensibility, will lead the technological evolution of K-culture,” and added, “I hope that KAIST’s spirit of challenge and research DNA will create a new wave in the entertech market.” Meanwhile, Galaxy Corporation, the agency of Professor G-Dragon Kwon Ji-yong, is an AI entertainment technology company that presents a new paradigm based on IP, media, tech, and entertainment convergence technology.

KAIST (President Kwang-Hyung Lee) announced on February 17th that it signed an agreement for cooperation in the bio-medical field with Formosa Group, one of the three largest companies in Taiwan. < Formosa Group Chairman Sandy Wang and KAIST President Kwang-Hyung Lee at the signing ceremony > Formosa Group Executive Committee member and Chairman Sandy Wang, who leads the group's bio and eco-friendly energy sectors, decided to establish a bio-medical research center within KAIST and invest approximately KRW 18 billion or more over 5 years. In addition, to commercialize the research results, KAIST and Formosa Group will establish a joint venture in Korea with KAIST Holdings, a KAIST-funded company. The cooperation between the two organizations began in early 2023 when KAIST signed a comprehensive exchange and cooperation agreement (MOU) with Ming Chi University of Science and Technology (明志科技大學), Chang Gung University (長庚大學), and Chang Gung Memorial Hospital (長庚記念醫院), which are established and supported by Formosa Group. Afterwards, Chairman Sandy Wang visited KAIST in May 2024 and signed a more specific business agreement (MOA). KAIST Holdings is a holding company established by KAIST, a government-funded organization, to attract investment and conduct business, and will pursue the establishment of a joint venture with a 50:50 equity structure in cooperation with Formosa Group. KAIST Holdings will invest KAIST’s intellectual property rights, and Formosa Group will invest a corresponding amount of funds. The KAIST-Formosa joint venture will provide research funds to the KAIST-Formosa Bio-Medical Research Center to be established in the future, secure the right to implement the intellectual property rights generated, and promote full-scale business. The KAIST-Formosa Bio-Medical Research Center will establish a ‘brain organoid bank’ created by obtaining tissues from hundreds of patients with degenerative brain diseases, thereby securing high-dimensional data that will reveal the fundamental causes of aging and disease. It is expected that KAIST’s world-class artificial intelligence technology will analyze large-scale patient data to find the causes of aging and disease. Through this business, it is expected that by 2030, five years from now, it will discover more than 10 types of intractable brain disease treatments and expand to more than 20 businesses, including human cell-centered diagnostics and preclinical businesses, and secure infrastructure and intellectual property rights that can create value worth approximately KRW 250 billion. The Chang Gung Memorial Hospital in Taiwan has 10,000 beds and handles 35,000 patients per day, and systematically accumulates patient tissue and clinical data. Chang Gung Memorial Hospital will differentiate the tissues of patients with degenerative brain diseases and send them to the KAIST-Formosa Bio-Medical Research Center, which will then produce brain organoids to be used for disease research and new drug development. This will allow the world’s largest patient tissue data bank to be established. Dean Daesoo Kim of the College of Life Science and Bioengineering at KAIST said, “This collaboration between KAIST and Formosa Group is a new research collaboration model that goes beyond joint research to establish a joint venture and global commercialization of developed technologies, and it is significant in that it can serve as an opportunity to promote biomedical research and development.” With this agreement, KAIST, which has been promoting the KAIST Advanced Regenerative Medicine Engineering Center in Osong K-Bio Square, has secured a practical global partner. < Representatives of the Formosa Group and KAIST > KAIST’s Senior Vice President for Planning and Budget, Professor Kyung-Soo Kim emphasized, “KAIST has made great efforts to secure an edge in state-of-the-art biomedical fields such as stem cells and gene editing technology, by attracting the world’s best experts and discovering global cooperation partners, and these results can ultimately be linked to the Osong K-Bio Square project.” SVP Kim then predicted, “In particular, the practical cooperation with Taiwan’s best Formosa Chang Gung Memorial Hospital, which has abundant clinical experience in stem cell treatment, will be an important axis of KAIST’s bio innovation strategy.” Formosa Chairman Sandy Wang emphasized that this investment and cooperation is built on trust in KAIST’s R&D capabilities and the passion of its researchers. And added that through this, the Formosa Group will practice corporate social responsibility and take an important first step together with KAIST to protect the welfare and health of humanity. She also went on the say that she expects to see the cooperation expanded to various fields such as mobility and semiconductors based on the successes begotten from the cooperation in the bio field. KAIST President Kwang-Hyung Lee said, “I evaluate this agreement as one of the most important events that will spearhead KAIST into overseas biotechnology stages,” and added, “I expect that this cooperation will be an opportunity for Taiwan and Korea, both of which have IT industry-centered structures, to create new growth engines in the bio industry.” Meanwhile, Formosa Group is a company founded by Chairman Sandy Wang’s father, Chairman Yung-Ching Wang. It is the world’s No. 1 plastic PVC producer and is leading core industries of the Taiwanese economy, including semiconductors, steel, heavy industry, bio, and batteries. Chairman Yung-Ching Wang was respected by the Taiwanese people for his exemplary return of wealth to society under the belief that the companies and assets he founded “belong to the people.”
