| ○ | Book chapter | Asian Male Rhinoplasty | In the new millennium, there has been a surge in men seeking plastic surgery, particularly in Asia, driven by evolving beauty standards and the rise of social media. This trend underscores the need for a specialized approach to male rhinoplasty, especially for Asian males. Asian male noses often have thick skin, a short and broad nasal bridge, and under-projected tips, among other unique features. In surgical practice, augmenting the bridge often requires grafts, either from autologous tissue or artificial implants. It is crucial to account for individual facial proportions when making decisions about nasal height and other dimensions. Considerations, especially for secondary procedures, must consider the thick skin and potential complications from prior use of silicone implants during the Asian male rhinoplasty. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. | Choi, Kang Young; Kim, Taek Kyun; Jeong, Jae Yong | Plastic and Reconstructive Surgery, School of Medicine, Kyungpook National University, Daegu, South Korea; The PLUS Plastic Surgery Clinic, Seoul, South Korea; The PLUS Plastic Surgery Clinic, Seoul, South Korea | 57203745682; 57208260369; 55261220700 | A Comprehensive Guide to Male Aesthetic and Reconstructive Plastic Surgery | 0 | 2025-05-07 | 0 | English | Final | 2024 | 10.1007/978-3-031-48503-9_26 | 바로가기 | 바로가기 | |||||||||||||||||||||
| ○ | Article | Assessing metal(loid)s-Induced long-term spatiotemporal health risks in Coastal Regions, Bay of Bengal: A chemometric study | Despite sporadic and irregular studies on heavy metal(loid)s health risks in water, fish, and soil in the coastal areas of the Bay of Bengal, no chemometric approaches have been applied to assess the human health risks comprehensively. This review aims to employ chemometric analysis to evaluate the long-term spatiotemporal health risks of metal(loid)s e.g., Fe, Mn, Zn, Cd, As, Cr, Pb, Cu, and Ni in coastal water, fish, and soils from 2003 to 2023. Across coastal parts, studies on metal(loid)s were distributed with 40% in the southeast, 28% in the south-central, and 32% in the southwest regions. The southeastern area exhibited the highest contamination levels, primarily due to elevated Zn content (156.8 to 147.2 mg/L for Mn in water, 15.3 to 13.2 mg/kg for Cu in fish, and 50.6 to 46.4 mg/kg for Ni in soil), except for a few sites in the south-central region. Health risks associated with the ingestion of Fe, As, and Cd (water), Ni, Cr, and Pb (fish), and Cd, Cr, and Pb (soil) were identified, with non-carcinogenic risks existing exclusively through this route. Moreover, As, Cr, and Ni pose cancer risks for adults and children via ingestion in the southeastern region. Overall non-carcinogenic risks emphasized a significantly higher risk for children compared to adults, with six, two-, and six-times higher health risks through ingestion of water, fish, and soils along the southeastern coast. The study offers innovative sustainable management strategies and remediation policies aimed at reducing metal(loid)s contamination in various environmental media along coastal Bangladesh. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024. | Aktar, Shammi; Islam, Abu Reza Md.

| ○ | Article | Assessment of indoor risk through deep learning -based object recognition in disaster situations | Disasters can devastate individuals and their properties, highlighting the importance of risk assessment to promote safety. Recently, deep learning techniques have shown the potential in identifying hazardous situations during disasters. Recognizing potentially dangerous objects in indoor environments can be essential for assisting individuals in responding appropriately to emergencies. In this article, we present an indoor-risk analysis framework for disasters based on deep learning. Our framework utilizes modern deep learning techniques to calculate an indoor risk rating based on dangerous objects’ sizes, enabling comprehensive risk assessment of indoor environments during disasters. To that end, we use (Mask R-CNN) to identify hazardous indoor objects in disaster situations with 94% accuracy. By incorporating object size information, our framework offers a more nuanced and detailed risk assessment than previous approaches. Our proposed system provides a valuable tool for promoting ongoing safety improvement and enhancing indoor safety during natural disasters. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023. | Khan, Irshad; Guo, Ziyi; Lim, Kihwan; Kim, Jaeseon; Kwon, Young-Woo | School of Computer Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Computer Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea; National Disaster Management Institute, Ulsan, 44538, South Korea; National Disaster Management Institute, Ulsan, 44538, South Korea; School of Computer Science and Engineering, Kyungpook National University, Daegu, 41566, South Korea | 36166674500; 58625582400; 57937218300; 57208390380; 57208480210 | ywkwon@knu.ac.kr; | Multimedia Tools and Applications | 1380-7501 | 83 | 12 | 0 | 2025-05-07 | 0 | Disaster assessment; Indoor safety; Object recognition; Risk level | Deep learning; Disasters; Hazards; Learning algorithms; Learning systems; Risk analysis; Risk assessment; Dangerous objects; Disaster assessment; Disaster situations; Indoor environment; Indoor safety; Learning techniques; Object size; Objects recognition; Risk levels; Risks assessments; Object recognition | English | Final | 2024 | 10.1007/s11042-023-16711-0 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Assessment of Serum Heat Shock Protein (HSP70) and Cortisol Concentration Change in Horses before and after an Acute Exercise | This study was conducted to secure basic data for improving the welfare of domestic breeding horses by measuring the accumulation of heart rate and lactic acid before and after exercise and measuring the concentration of Cortisol and HSP70 as indicators for horse stress. For three sessions before exercise, immediately after exercise, and 30 min after exercise, 15 Thoroughbred racing horses and 15 riding horses in domestic breeding were designated, and lactate was measured in plasma using a poly equine health check Polar H10 heart rate meter. In addition, the concentrations of HSP70 and Cortisol, which can be taken as values of stress in three sessions, were analyzed. The levels of HSP70 were measured as 29.43±5.72pg/mL before exercise, 89.74±23.02pg/mL after exercise, 32.19±6.57pg/mL after 30 min of exercise, 41.25±8.26pg/mL before exercise, and 114.02±29pg/mL after exercise (pg/mL) after exercise. Cortisol concentrations were found to be 3.38±1.2µg/dL before exercise, 5.11±1.16µg/dL immediately after exercise, 5.58±2.15µg/dL after 30 min of exercise, 6.61±2.04µg/dL before exercise, 8.47±2.55µg/dL immediately after exercise, and 30 min after exercise. Hematology chemistry in riding horse and racing horses had some differences by items, but there was no significant difference overall. In conclusion, it has been confirmed that racing horses have higher stress from strong exercise compared to riding horses, and plans to use it to promote the welfare of domestic horses in the future. © 2024, Unique Scientific Publishers.

| ○ | ○ | Article | Association between Height and Functional Outcomes of Patients 6 Months after a Stroke: A Multicenter Prospective Observational Cohort Study | Many physical factors influence post-stroke functional outcomes. However, few studies have examined the influence of height on these outcomes. Here, data from the Korean Stroke Cohort for Functioning and Rehabilitation were used and patients' height was categorized into three groups: short (lower 25%), middle (middle 50%), and tall (upper 25%). Differences in the modified Rankin scale (mRS), functional ambulatory category (FAC), and Korean-translated version of the Modified Barthel Index (K-MBI) scores were analyzed for each group at 6 months post-stroke. A subgroup analysis was conducted based on the initial Fugl-Meyer Assessment (FMA) score. We analyzed functional outcomes in 5296 patients at 6 months post-stroke, adjusting for age and body mass index. The short-height group exhibited higher mRS scores (1.88 +/- 0.043), lower FAC scores (3.74 +/- 0.045), and lower K-MBI scores (82.83 +/- 0.748) than the other height groups (p < 0.05). In the subgroup analysis, except for the very severe FMA group, the short-height group also exhibited worse outcomes in terms of mRS, FAC, and K-MBI scores (p < 0.05). Taken together, the short-height group exhibited worse outcomes related to disability, gait function, and ADLs at 6 months post-stroke. | Kang, Nae Yoon; Ko, Sung-Hwa; Shin, Yong-Il; Min, Ji Hong; Yun, Mi Sook; Sohn, Min Kyun; Lee, Jongmin; Kim, Deog Young; Oh, Gyung-Jae; Lee, Yang Soo; Joo, Min Cheol; Lee, So Young; Song, Min-Keun; Han, Junhee; Ahn, Jeonghoon; Kim, Yun-Hee; Chang, Won Hyuk | Pusan Natl Univ, Sch Med, Pusan Natl Univ Hosp, Dept Rehabil Med, Yangsan 50612, South Korea; Pusan Natl Univ, Yangsan Hosp, Res Inst Convergence Biomed Sci & Technol, Yangsan 50612, South Korea; Pusan Natl Univ, Res Inst Convergence Biomed Sci & Technol, Div Biostat, Yangsan Hosp, Yangsan 50612, South Korea; Chungnam Natl Univ, Sch Med, Dept Rehabil Med, Daejeon 35015, South Korea; Konkuk Univ, Sch Med, Dept Rehabil Med, Seoul 05029, South Korea; Yonsei Univ, Dept & Res Inst Rehabil Med, Coll Med, Seoul 03722, South Korea; Wonkwang Univ, Sch Med, Dept Prevent Med, Iksan 54538, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Rehabil Med, Daegu 41944, South Korea; Wonkwang Univ, Sch Med, Dept Rehabil Med, Iksan 54538, South Korea; Jeju Natl Univ, Sch Med, Dept Internal Med, Jeju 63241, South Korea; Chonnam Natl Univ, Dept Phys & Rehabil Med, Med Sch, Gwangju 61469, South Korea; Hallym Univ, Dept Stat, Chunchon 24252, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul 03760, South Korea; Sungkyunkwan Univ, Heart Vasc & Stroke Inst, Ctr Prevent & Rehabil, Samsung Med Ctr,Dept Phys & Rehab Med, Seoul 06351, South Korea | ; Kim, Yun-Hee/GVS-6426-2022; Chang, Won Hyuk/I-5662-2015; kim, deog young/Q-8498-2019; Lee, Jongmin/Q-4909-2019; Ahn, Jeonghoon/CAA-1956-2022 | 58629797300; 55376767400; 55890990500; 57217330746; 57220778861; 7101840459; 57202882113; 55375583000; 7007056685; 57202952463; 56982599700; 57202327370; 55375416600; 57192890252; 8855402200; 57020121600; 35301717900 | dr.knybs12@gmail.com;ijsh6679@gmail.com;rmshin01@gmail.com;papered@hanmail.net;msyun@pusan.ac.kr;mksohn@cnu.ac.kr;leej@kuh.ac.kr;kimdy@yuhs.ac;pmokj@wku.ac.kr;leeyangsoo@knu.ac.kr;jmc77@hanmail.net;bluelsy900@hanmail.net;drsongmk@daum.net;pnuyh.rass@gmail.com;ahnjeonghoon@ewha.ac.kr;yun1225.kim@samsung.com;wh.chang@samsung.com; | JOURNAL OF PERSONALIZED MEDICINE | 2075-4426 | 14 | 6 | 0 | 2025-05-07 | 0 | 0 | post-stroke recovery; functional outcomes; height; stroke rehabilitation; disability; activities of daily living | MOTOR RECOVERY; RELIABILITY; GAIT; PERFORMANCE; BALANCE; IMPACT | activities of daily living; disability; functional outcomes; height; post-stroke recovery; stroke rehabilitation | adult; aged; Article; body mass; cerebrovascular accident; cohort analysis; computed tomographic angiography; daily life activity; female; Fugl-Meyer assessment; human; knee function; magnetic resonance angiography; major clinical study; male; observational study; occupational therapy; outcome assessment; physiotherapy; Rankin scale; stroke patient; stroke rehabilitation | English | 2024 | 2024-06 | 10.3390/jpm14060610 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | ATB Extraction in the Box System* | This study critically examines the well-established analyses of across-the-board (ATB) extraction, ranging from movement-based to copy-based to Merge-based approaches, within the framework of the Strong Minimalist Thesis (SMT). Merge, considered the most economical structure building operation, is expected to meet Minimal Yield (MY) by introducing the fewest possible new items into the workspace (WS). Adherence to this principle aligns Merge with SMT, whereas the previous accounts for ATB extraction deviate from MY. Chomsky (2021) provides an account for ATB extraction within the Merge framework while maintaining the segregation of A/A’-movement. However, issues stemming from this segregation lead Chomsky (2023a) to propose the box theory, aiming to eliminate distinctions between A/A’-movement. This study will delve into the box theory, identifying challenges related to ATB extraction. Utilizing precise definitions of eligibility and accessibility, we will argue that the specifier of INFL (SPEC-INFL) remains accessible to phase heads with restriction of Phase Impenetrability Condition (PIC) despite being ineligible for Merge. Additionally, we will incorporate Mizuguchi’s (2019) proposal that posits a phonetically null complementizer forms a composite head with INFL. With these refinements, ATB extraction can be successfully explained within the box system, adhering to SMT. Our analysis aligns with Chomsky’s (2023a) perspective of eliminating successive-cyclic A/A’-movement, effectively eliminating distinctions between A/A’ movement. © 2024 KASELL All rights reserved. | Lee, Kyoungmi | Department of English Language and Literature, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, South Korea | 58917467800 | kmlee2007@gmail.com; | Korean Journal of English Language and Linguistics | 1598-1398 | 24 | 1 | 2025-04-16 | 1 | across-the-board (ATB); box theory; cyclicity; Merge; Strong Minimalist Thesis (SMT) | English | Final | 2024 | 10.15738/kjell.24..202402.127 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | AtGATA12 directly activates the master regulator of secondary cell all formation | The secondary cell wall is composed of cellulose, hemicellulose, and lignin, and some of the genetic pathways responsible for their synthesis have been elucidated. In the secondary cell wall biosynthesis pathway, there are downstream genes that can synthesize each component, hub genes that can regulate these genes, and master regulators that control genes at the top of the pathway. AtGATA12, a member of the GATA family, is a gene that is highly expressed in plant stems, but its role has not been clearly studied. In this study, we confirmed that the role of AtGATA12 in the plant secondary cell wall biosynthesis pathway involves the regulation of master regulators. AtGATA12 functions as a transcription factor in Arabidopsis, regulating the expression of secondary cell wall genes and directly controlling master regulators such as ANAC012, NST1, and VND7. Additionally, the secondary cell wall of the interfascicular fiber in the Arabidopsis stem was thickened. Therefore, we demonstrated that AtGATA12 has the ability to regulate secondary cell wall biosynthesis in Arabidopsis and can directly control several master regulators. © The Korean Society for Applied Biological Chemistry 2024. | Lim, Ki-Hwan; Kim, Won-Chan | Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea, Gyeongsangbuk-do Agicultureal Reseaerch & Extension Services, Daegu, 41404, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea | 59304376800; 55492085000 | kwc@knu.ac.kr; | Journal of Applied Biological Chemistry | 1976-0442 | 67 | 1 | 0 | 2025-05-07 | 0 | GATA family; Master regulator; Secondary cell wall; Transcription factor | Korean | Final | 2024 | 10.3839/jabc.2024.037 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | ATTENTION-BASED ITERATIVE DECOMPOSITION FOR TENSOR PRODUCT REPRESENTATION | In recent research, Tensor Product Representation (TPR) is applied for the systematic generalization task of deep neural networks by learning the compositional structure of data. However, such prior works show limited performance in discovering and representing the symbolic structure from unseen test data because their decomposition to the structural representations was incomplete. In this work, we propose an Attention-based Iterative Decomposition (AID) module designed to enhance the decomposition operations for the structured representations encoded from the sequential input data with TPR. Our AID can be easily adapted to any TPR-based model and provides enhanced systematic decomposition through a competitive attention mechanism between input features and structured representations. In our experiments, AID shows effectiveness by significantly improving the performance of TPR-based prior works on the series of systematic generalization tasks. Moreover, in the quantitative and qualitative evaluations, AID produces more compositional and well-bound structural representations than other works. © 2024 12th International Conference on Learning Representations, ICLR 2024.

| ○ | Article | Atypical loculated pericardial effusion with infectious pericarditis mimicking a cardiac mass in a dog: a case report | A 13-year-old, Maltese dog presented with syncope and lethargy. Abdominal ultrasonography demonstrated anechoic peritoneal effusion and hepatic congestion. A focal echogenic round mass compressing the right ventricle and atrium was observed on echocardiography. Cardiac tamponade and right ventricular outflow tract obstruction occurred. On computed tomography, a homogeneous soft-tissue structure compressing the right chamber without contrast enhancement, suspected to be loculated pericardial effusion. During pericardiocentesis, cardiac tamponade was resolved, and irregular pericardial thickening was noted. Pericardial effusion was exudate and gram-positive bacterial colonies were observed on cytology. A diagnosis of fibrinous pericarditis secondary to bacterial infection was established. 2024 The Korean Society of Veterinary Science. | Lee, Ji-Yun; Bae, Seulgi; Park, Jin-Kyu; Jang, Min; Lee, Kija; Lee, Sang-Kwon | Department of Veterinary Medical Imaging, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; Department of Veterinary Internal Medicine, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; Department of Veterinary Pathology, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; Department of Veterinary Surgery, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; Department of Veterinary Medical Imaging, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; Department of Veterinary Medical Imaging, College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea | 59231673900; 55418865900; 35213723500; 55341507600; 35311016000; 56494541400 | sklee10@knu.ac.kr; | Korean Journal of Veterinary Research | 2466-1384 | 64 | 2 | 0 | 2025-05-07 | 0 | computed tomography; dogs; echocardiography; heart; heart neoplasms | English | Final | 2024 | 10.14405/kjvr.20240022 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Automated Quantification of Total Cerebral Blood Flow from Phase-Contrast MRI and Deep Learning | Knowledge of input blood to the brain, which is represented as total cerebral blood flow (tCBF), is important in evaluating brain health. Phase-contrast (PC) magnetic resonance imaging (MRI) enables blood velocity mapping, allowing for noninvasive measurements of tCBF. In the procedure, manual selection of brain-feeding arteries is an essential step, but is time-consuming and often subjective. Thus, the purpose of this work was to develop and validate a deep learning (DL)-based technique for automated tCBF quantifications. To enhance the DL segmentation performance on arterial blood vessels, in the preprocessing step magnitude and phase images of PC MRI were multiplied several times. Thereafter, a U-Net was trained on 218 images for three-class segmentation. Network performance was evaluated in terms of the Dice coefficient and the intersection-over-union (IoU) on 40 test images, and additionally, on externally acquired 20 datasets. Finally, tCBF was calculated from the DL-predicted vessel segmentation maps, and its accuracy was statistically assessed with the correlation of determination (R2), the intraclass correlation coefficient (ICC), paired t-tests, and Bland-Altman analysis, in comparison to manually derived values. Overall, the DL segmentation network provided accurate labeling of arterial blood vessels for both internal (Dice=0.92, IoU=0.86) and external (Dice=0.90, IoU=0.82) tests. Furthermore, statistical analyses for tCBF estimates revealed good agreement between automated versus manual quantifications in both internal (R2=0.85, ICC=0.91, p=0.52) and external (R2=0.88, ICC=0.93, p=0.88) test groups. The results suggest feasibility of a simple and automated protocol for quantifying tCBF from neck PC MRI and deep learning. | Kim, Jinwon; Lee, Hyebin; Oh, Sung Suk; Jang, Jinhee; Lee, Hyunyeol | Kyungpook Natl Univ, Sch Elect & Elect Engn, IT1 603,Daehak Ro 80, Daegu 41075, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Coll Med, Dept Radiol, Seoul, South Korea; Daegu Gyeongbuk Med Innovat Fdn K MEDI Hub, Med Device Dev Ctr, Daegu, South Korea | 59937048200; 59937048300; 59937950200; 49461420500; 57193268117 | hyunyeollee@knu.ac.kr; | JOURNAL OF IMAGING INFORMATICS IN MEDICINE | J IMAGING INFORM MED | 2948-2925 | 2948-2933 | 37 | 2 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | N/A | 0.45 | 2025-06-11 | 1 | 1 | Cerebral blood flow; Deep learning; Phase-contrast MRI; Quantification; Vessel segmentation | POSITRON-EMISSION-TOMOGRAPHY; OXYGEN-METABOLISM; BRAIN; PERFUSION; IMAGE; DISEASE; CBF | Cerebral blood flow; Deep learning; Phase-contrast MRI; Quantification; Vessel segmentation | Diseases; Dynamic contrast enhanced MRI; Neurophysiology; Arterial blood; Blood velocity; Cerebral blood flow; Deep learning; Intraclass correlation coefficients; Non- invasive measurements; Phase contrast magnetic resonance imaging; Quantification; Velocity mapping; Vessel segmentation; Image segmentation | English | 2024 | 2024-04 | 10.1007/s10278-023-00948-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Bacterial Contamination of Veterinary Ear Cleaners in Homes and Clinics | Ear cleaning using ear cleaners is recommended for the prevention of canine otitis externa. This study aimed to investigate the prevalence of bacterial contamination in home-and clinical-use ear cleaners and identify characteristics associated with such a prevalence. To obtain data regarding home-use ear cleaners, 100 bottles of commercial ear cleaners were collected from clients who visited animal clinics with their dogs and completed a survey. Data for clinic-use ear cleaners were obtained by gathering 60 bottles of ear cleaners from private animal hospitals. Bacterial culture of the applicator tips and samples of the ear cleaners was performed. In addition, to determine the relationship between ear cleaner contamination and otitis externa (OE) in dogs, ear cultures were obtained from some of the dogs that visited the clinics. Approximately 5% and 4.91% of home-and clinic-use ear cleaner applicator tips, respectively, had bacterial contamination, although no contamination of the solution within the bottles was observed. Most of the contaminated ear cleaner tips were unclean on the outside given that the bottle was placed directly into the ear canal. The contamination rate was highest among owners who used ear cleaners once a week and among veterinarians who used the product for dogs with OE. We found no ingredients that affected the incidence of ear cleaner contamination. © The Korean Society of Veterinary Clinics. | Kim, Soonjoo; Kim, Minji; Suh, Hyerin; Lee, Junho; Bae, Seulgi; Oh, Taeho | College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea; College of Veterinary Medicine, Kyungpook National University, Daegu, 41566, South Korea | 59479527800; 57127351600; 58351370500; 57219032336; 59461572500; 8251199600 | sgbae@knu.ac.kr;thoh@knu.ac.kr; | Journal of Veterinary Clinics | 1598-298X | 41 | 5 | 0 | 2025-05-07 | 0 | bacteria; dog; ear cleaners | Acinetobacter; Article; auditory canal; bacterial load; bacterium contamination; bacterium culture; bacterium isolation; Brevibacterium; cleaning; dog; Ear cleaning; ear infection; ear swab; Enterococcus; Enterococcus faecalis; external otitis; Fisher exact test; nonhuman; polymerase chain reaction; Pseudomonas aeruginosa; Staphylococcus pseudintermedius; veterinary clinic; veterinary medicine | English | Final | 2024 | 10.17555/jvc.2024.41.5.287 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Proceedings Paper | Balancing Control of Cluster Energy in Star-Connected Multilevel Power Conversion System Using Zigzag Transformer | In star-connected cascaded H-bridge converters, it is common to make use of a zero-sequence voltage as a control element for cluster energy balance control. Therefore, during the converter design process, it is crucial to consider and secure the sufficient cluster voltage margin to accommodate this zero-sequence voltage. The proposed method offers a way to reduce the number of submodule cells while maintaining the same output voltage. This reduction is achieved by introducing a zigzag transformer to create a zero-sequence current path. This zero-sequence current can then serve as the control factor for cluster energy balancing, and a dedicated control scheme can be developed. One noteworthy advantage of this approach is that the zero-sequence current can effectively address cluster energy balance even in light load conditions of the star-connected cascaded H-bridge converter, as well as during grid and load imbalances. To validate the feasibility of the proposed method, simulation and experimental studies were conducted. The results confirm the effectiveness and practical applicability of the approach in achieving cluster energy balance under various operating conditions. | Kim, Yeongung; Cui, Shenghui; Jung, Jae-Jung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Seoul Natl Univ, Dept Elect & Comp Engn, Seoul, South Korea | Jung, Jae-Jung/AAG-4515-2021 | 59118791000; 56157479900; 55368433400 | free77a@knu.ac.kr;cuish@snu.ac.kr;jj.jung@knu.ac.kr; | 2024 IEEE APPLIED POWER ELECTRONICS CONFERENCE AND EXPOSITION, APEC | 1048-2334 | 0 | 2025-04-16 | 0 | 0 | Cascaded H-bridge converter (CHB); cluster balancing; leg balancing; static synchronous compensator (STATCOM); zero-sequence current injection | STATCOM; CONVERTERS; INVERTER | Cascaded H-bridge converter (CHB); cluster balancing; leg balancing; static synchronous compensator (STATCOM); zero-sequence current injection | Bridge circuits; Electric current regulators; Energy balance; Power control; Power converters; Power electronics; Power quality; Stars; Cascaded H-bridge converter; Cluster balancing; Cluster energy; Leg balancing; Static synchronoi compensator; Zero sequence current; Zero sequence current injection; Zero sequence voltage; Zigzag transformer; Static synchronous compensators | English | 2024 | 2024 | 10.1109/apec48139.2024.10509341 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Conference paper | Ballistic transport in state-of-the art In0.65Ga0.35As/In0.52Al0.48As quantum-well high-electron-mobility transistors at room and cryogenic temperatures | This paper presents a systematic analysis of ballistic transport in state-of-the-art In0.65Ga0.35As QW HEMTs at both room and cryogenic temperatures. We examine devices with a wide range of gate lengths from 300 nm to sub-100 nm, to study near-ballistic transport, particularly in terms of ballistic mobility and mean-free-path, especially at 4 K. We also consider the impact of channel carrier degeneracy in the In0.65Ga0.35As QW channel layer, which arises from the relatively low density of states in this layer. Our work underscores the significant role of ballistic mobility in state-of-the art In0.65Ga0.35As HEMTs from 300 K to 4 K. It reveals that quantum-mechanical ballistic transport and channel degeneracy must be accounted for during device modeling and characterization. Furthermore, we propose a methodology to graphically determine whether carrier transport is governed by conventional diffusive transport or near-ballistic transport in terms of channel carrier degeneracy and Lg at each temperature ranging from 300 K to 4 K. © 2024 IEEE. | Son, Seung-Woo; Lee, In-Geun; Yu, Min-Seo; Choi, Su-Min; Jeon, Yong-Soo; Son, Sang-Pyeong; Yoo, Ji-Hoon; Yun, Sang-Ki; Kim, Tae-Woo; Lee, Jae-Hak; Yang, Kyounghoon; Kim, Dae-Hyun | School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; Texas Technology University, United States; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea; KAIST, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, South Korea | 57206473214; 37016357200; 59322272900; 57825819100; 59001406600; 59322351500; 57545572700; 59669783100; 57203495132; 55690077600; 7404291550; 57212363794 | dae-hyun.kim@ee.knu.ac.kr; | Technical Digest - International Electron Devices Meeting, IEDM | 0163-1918 | 0 | 2025-05-07 | 0 | Gallium alloys; Gallium compounds; High electron mobility transistors; III-V semiconductors; Mercury amalgams; Semiconducting indium phosphide; Ballistic transports; Channel carriers; Cryogenic temperatures; Gate-length; High electron-mobility transistors; Mean-free path; Quantum-wells; State of the art; Sub-100 nm; Systematic analysis; Semiconductor quantum wells | English | Final | 2024 | 10.1109/iedm50854.2024.10873407 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Conference paper | Behavior of Isotropic and Anisotropic Diaphragm Walls in Finite Element Analysis Model of Deep Excavation | The diaphragm wall of the deep excavation pit is the Barrette pile connected, standing side by side in a row to create a diaphragm wall system, so that the flexural stiffness of the diaphragm wall in the vertical and the horizontal direction is different. That is, the horizontal stiffness (axis 2) will be less than the vertical stiffness (axis 1) E2I2 << E1I1. In this study, the author analyzes and simulates the Barrette pile diaphragm wall system working according to the 3D model of the Song-San excavation project located in the K1 area of the Taipei basin, Taiwan. The results are checked and compared with the actual measurement results. Through the process of analyzing and observing the obtained results, the author draws a few conclusions as follows: Firstly, the influence of the corner effect and the stiffness of the diaphragm wall in the horizontal direction is realistic and needs to be considered. In consideration, it is necessary to simulate the deep excavation according to the 3D model to analyze and properly evaluate this problem. Secondly, the simulation of the deep excavation according to the 2D model only properly evaluates the behavior of the diaphragm wall in the middle of the long edge segment (L) of the excavation, on the middle L/2 segment and when considering the behavior of the diaphragm wall on the L/4 segment from the corner of the diaphragm wall, it should be considered on the 3D model. Third, in order to quickly model and save time for discrete analysis of many elements, in preliminary calculations, it is possible to accept the diaphragm wall simulation as a continuous wall (W-IP) combined with correction the stiffness of the diaphragm wall in the horizontal direction through the ratio n = I2/I1 = 0.76. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Nguyen, Nhut-Nhut; To, Le Huong; Le, Ba Vinh | Ho Chi Minh City University of Technology (HCMUT), 268 Ly Thuong Kiet Street, District 10, Ho Chi Minh City, Viet Nam, Vietnam National University Ho Chi Minh City, Linh Trung Ward, Thu Duc City, Ho Chi Minh City, Viet Nam, Department of Civil Engineering, Kyungpook National University, Daegu, South Korea; Ho Chi Minh City University of Technology (HCMUT), 268 Ly Thuong Kiet Street, District 10, Ho Chi Minh City, Viet Nam, Vietnam National University Ho Chi Minh City, Linh Trung Ward, Thu Duc City, Ho Chi Minh City, Viet Nam; Ho Chi Minh City University of Technology (HCMUT), 268 Ly Thuong Kiet Street, District 10, Ho Chi Minh City, Viet Nam, Vietnam National University Ho Chi Minh City, Linh Trung Ward, Thu Duc City, Ho Chi Minh City, Viet Nam | 57211211964; 58771733200; 57218492101 | tolehuong@hcmut.edu.vn; | Lecture Notes in Civil Engineering | 2366-2557 | 442 | 0 | 2025-04-16 | 0 | Barrette pile; Deep excavation; Diaphragm wall; Finite element; Plaxis; Simulation | 3D modeling; Diaphragms; Excavation; Finite element method; Stiffness; 3D models; 3d-modeling; Barrette pile; Deep excavation; Diaphragm wall; Finite element; Isotropics; Plaxis; Simulation; Wall systems; Piles | English | Final | 2024 | 10.1007/978-981-99-7434-4_110 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Benchmarking the performance and uncertainty of machine learning models in estimating scour depth at sluice outlets | This study investigates the performance of six machine learning (ML) models - Random Forest (RF), Adaptive Boosting (ADA), CatBoost (CAT), Support Vector Machine (SVM), Lasso Regression (LAS), and Artificial Neural Network (ANN) - against traditional empirical formulas for estimating maximum scour depth after sluice gates. Our findings indicate that ML models generally outperform empirical formulas, with correlation coefficients (CORR) ranging from 0.882 to 0.944 for ML models compared with 0.835-0.847 for empirical methods. Notably, ANN exhibited the highest performance, followed closely by CAT, with a CORR of 0.936. RF, ADA, and SVM performed competitive metrics around 0.928. Variable importance assessments highlighted the dimensionless densimetric Froude number (Fd) as significantly influential, particularly in RF, CAT, and LAS models. Furthermore, SHAP value analysis provided insights into each predictor's impact on model outputs. Uncertainty assessment through Monte Carlo (MC) and Bootstrap (BS) methods, with 1,000 iterations, indicated ML's capability to produce reliable uncertainty maps. ANN leads in performance with higher mean values and lower standard deviations, followed by CAT. MC results trend towards optimistic predictions compared with BS, as reflected in median values and interquartile ranges. This analysis underscores the efficacy of ML models in providing precise and reliable scour depth predictions. | Le, Xuan-Hien; Le, Thu Hien Thi; Ho, Hung Viet; Lee, Giha | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, 2559 Gyeongsang Daero, Sangju 37224, South Korea; Thuyloi Univ, Fac Water Resources Engn, 175 Tay Son, Hanoi 10000, Vietnam | ; Le, Xuan-Hien/AAZ-9166-2021; Le, Thu Hien/JGM-4466-2023 | 57209735659; 57210202660; 57209738753; 35069799400 | hienlx@knu.ac.kr; | JOURNAL OF HYDROINFORMATICS | 1464-7141 | 1465-1734 | 26 | 7 | 3.46 | 2025-05-07 | 8 | 9 | machine learning; Monte Carlo simulation; scour depth estimation; SHAP values; sluice gate; uncertainty quantification | ANFIS-BASED APPROACH; LOCAL SCOUR; PREDICTION; DOWNSTREAM; EROSION; APRON; GATE | machine learning; Monte Carlo simulation; scour depth estimation; SHAP values; sluice gate; uncertainty quantification | English | 2024 | 2024-07 | 10.2166/hydro.2024.297 | 바로가기 | 바로가기 | 바로가기 |
