Professor Hanjung Lee’s Research Team Identifies the Principles Behind English Sentence Structure Choices Through Big Data Analysis - First to identify contextual factors influencing realization of causal event structures ▲(From left) First author: Ph.D. candidate Ji-Yeon Kim, Corresponding author: Professor Hanjung Lee, Co-author: Ph.D. candidate Ye-Eun Cho A research team led by Professor Hanjung Lee from the Department of English Language and Literature at Sungkyunkwan University (SKKU) has published a paper in the internationally renowned journal Corpus Linguistics and Linguistic Theory, revealing the key factors that influence the choice of causal event structures in English sentences. The study was conducted by the Language, Cognition, and Artificial Intelligence research group, consisting of Professor Hanjung Lee (Department of English Language and Literature), Ph.D. candidate Ji-Yeon Kim (Department of German Language and Literature), and Ph.D. candidate Ye-Eun Cho (Department of English Language and Literature). The team extracted approximately 15,000 sentences describing events caused by direct causes from the British National Corpus (BNC)—a corpus of about 100 million words commonly used in English language research—using natural language processing (NLP) tools. They then conducted both qualitative analyses and machine-learning-based multifactorial analyses. The results showed that the clarity and intentionality of the cause are the most significant factors influencing how causal event structures are realized. For instance, structures where the agent is explicitly mentioned, such as "The protesters broke the window," are influenced by different factors than structures where the cause is implicit, such as "The window broke" or "The window was broken." In addition, the study identified various contextual conditions affecting the choice between active and passive constructions, empirically demonstrating how linguistic informativeness, contextual appropriateness, and communicative efficiency interact to govern language use. This research was supported by the National Research Foundation of Korea. As a follow-up, the team is currently investigating how non-verbal perceptual factors influence language expression across English and Korean speakers, as well as artificial intelligence language models. Professor Lee stated, “We plan to continue pioneering research that explores the intersection of language, cognition, emotion, perception, and culture, utilizing large language models such as GPT and BERT.” ※ Title: Semantic and contextual constraints on the causative alternation in English: A multifactorial analysis ※ Journal: Corpus Linguistics and Linguistic Theory (De Gruyter Brill) ※ Author: Ji-Yeon Kim (First Author), Hanjung Lee (Corresponding Author), Ye-Eun Cho (Co-Author) ※ Link: https://doi.org/10.1515/cllt-2024-0047

Undergraduate student majoring in English Language and Literature and Library and Information Science, published an SSCI paper (supervised by Professor Na-yeon Kim) ▲ (from left) Ziying Li, a doctoral student, Professor Na-yeon Kim, Chaejin Lee (English Language and Literature), Seong-hyun Byun (Library and Information Science) The research paper led by Professor Na-yeon Kim of the Department of English Language and Literature, titled "Zero-derivation in Korean: the effect of covert structure in real-time processing," has been published in the December issue of the SSCI journal 'Frontiers in Psychology: Psychology Of Language.' The paper explores the linguistic and cognitive aspects of words with ambiguous grammatical categories, revealing their subtle syntactic structures through both linguistic and cognitive psychological methodologies. Notably, this paper holds significant meaning as it is a collaborative effort, not only involving Ziying Li, a doctoral student, but also featuring contributions from undergraduate students, Chae-jin Lee, a third-year English Language and Literature major, and Seong-hyun Byun, a fourth-year student majoring in Library and Information Science. The research focuses on the phenomenon of 'zero-derivation' in Korean. For instance, in Korean, the word '밝다' ('bright') can be used both as an adjective and a verb. While previous studies have explored the phenomenon of adjectives and verbs sharing grammatical categories, there has been no experimental study determining whether such categories are distinct or if the verb '밝다' derives from the adjective '밝다.' This study analyzes the process by which the verb '밝다' is derived from the adjective '밝다' through cognitive psychological methodologies. It reveals that we can easily understand sentences by being sensitive to the unseen syntactic structures and the derivation process of grammatical categories. The study suggests that sentences with omitted words, i.e., those not visible or audible, also possess delicate and intricate syntactic structures. Humans can recognize these structures, enabling them to quickly comprehend sentences involving omissions. The research team is currently collaborating with professors from foreign language departments at the University of Toronto, Northwestern University, and the National University of Singapore to systematize various syntactic experiments that elucidate the interaction mechanism between these subtle syntactic structures and cognitive processes. Additionally, ongoing research at our university's Artificial Intelligence Convergence Institute, led by Professor Kwang-soo Kim, explores whether artificial intelligence can acquire these unique language characteristics exhibited by humans. Professor Na-yeon Kim expressed, "It's commendable that two undergraduate research students and a doctoral student have passionately contributed to this research for over a year, dedicating weekends. In the future, I plan to further expand opportunities for collaborative research with students in the field of interdisciplinary research between English language and cognitive psychology through the Language and Cognition Lab." ※ Author: Kim, N., Li, Z., Byeon, S., & Lee, C. ※ Title: Zero-derivation in Korean: The Effect of Covert Structure in Real-time Processing. ※ Journal: Frontiers in Psychology,14, 1230927

SAINT faculty Seongpil An and Il Jeon co-research team, developed a highly transparent and multifunctional wearable nanogenerator -Multifunctional piezoelectric nanogenerator for energy harvesting and motion sensing in next-generation wearable electronics -Winner of 2022 SKKU Graduate Student Paper Award ▲ (From left) Professor Seongpil An, Doctoral student Kiyong Kim, Doctoral student Sangsu Lee, Professor Il Jeon. Profs. Seongpil An and Il Jeon’s co-research team from SKKU Advanced Institute of Nanotechnology (SAINT) announced that they have developed a multifunctional transparent composite that can harvest energy, composed of piezoelectric polymer nanofibers and high-purity carbon nanotubes (CNTs) as the core materials. In previous studies, silver nanowires or electrically conductive polymers, such as PEDOT:PSS, were used as electrodes for transparent PENGs. However, metal-based transparent PENGs have inherent issues of opacity due to their natural light reflection and scattering, while electrically conductive polymer-based PENGs have shown material limitations in mechanical properties with insufficient electrical conductivity. The co-research team developed a multifunctional transparent composite capable of harvesting energy using a silicon-based elastomer embedded with piezoelectric polymer nanofibers and high-purity CNTs. The team developed piezoelectric P(VDF-TrFE) nanofibers with a diameter of 500 nm, 200 times thinner than a human hair, using the electrospinning technique and embedded them in a transparent silicon-bsed elastomer PDMS. They also used a differentiated aerosol-assisted chemical vapor deposition (CVD) method to produce transparent CNT films for their use as electrodes in the development of a transparent PENG. The electrospinning and aerosol CVD methods used in this study are not only simple to use but also easily scalable to larger production scales compared to other methods. Based on these excellent process advantages, it is expected to have a positive impact on the commercialization of related technologies in the future. In particular, in this study, the conductivity of the CNT electrode could be improved by 3.1 times through a simple chemical doping method. The developed high-transparency PENG demonstrated decent energy harvesting performance that generated a voltage of 10 V or more even with relatively weak external force (F = 10 N). Additionally, it showed high energy harvesting performance under repetitive external force conditions of over 50,000 cycles, proving excellent mechanical durability and stability. Furthermore, when the external force was applied through a body part, such as fingers, it exhibited higher energy harvesting performance of up to 26.8 V through an additional effect of triboelectricity. ▲ Transparent PENG developed and its fabrication process It is expected that the newly developed transparent PENG can be applied extensively in the rapidly growing fields of metaverse, virtual/augmented reality, as it can not only detect subtle movements of the human body in real time by attaching it to various parts of the body, but also generate voltage signals sensitively in response to changing external forces. This study was published on January 18th in Advanced Functional Materials (IF: 19.924), a world-renowned academic journal in the top 5% of the material science field, based on the results that won the SKKU Graduate Student Paper Award. The lead authors of this paper are beginner in doctoral course, so their future research activities are highly anticipated. ※ Title: Highly Transparent and Mechanically Robust Energy-harvestable Piezocomposite with Embedded 1D P(VDF-TrFE) Nanofibers and Single-walled Carbon Nanotubes ※ Journal: Advanced Functional Materials ※ DOI: https://onlinelibrary.wiley.com/doi/10.1002/adfm.202213374
