| ○ | ○ | Article | Numerically Investigating the Energy-Harvesting Performance of an Oscillating Flat Plate with Leading and Trailing Flaps | This study investigates the power generation capability of an oscillating wing energy harvester equipped with two actively controlled flaps positioned at the leading and trailing flaps of the wing. Various parameters, including flap lengths and pitch angles for the leading flap and trailing flap, are explored through numerical simulations. The length of the main wing body ranges from 40% to 65% of the chord length, c, while the leading and trailing flaps vary accordingly, summing up to the total length of the flat plate c = 100%. The pitch angles of the two flaps are adjusted within predefined limits. The pitch angle for the leading flap varies between 25 degrees and 55 degrees, while the trailing flap's angle ranges from 10 degrees to 40 degrees across 298 different simulation scenarios. The results indicate that employing both leading and trailing flaps enhances the power output compared to a wing with a single flap configuration. The trailing flap deflects the incoming fluid more vertically, while the leading flap increases pressure difference across the surface of the main wing body, synergistically improving overall performance. The power output occurs at a specific length percentage: a leading flap of 30%, a main wing body of 50%, and a trailing flap of 20%, with pitch angles of 50 degrees, 85 degrees, and 30 degrees, respectively, increasing the output power increments by 4.39% compared to a wing with a leading flap, 4.92% compared to a wing with a trailing flap, and 28.24% compared to a single flat plate. The highest efficiency for the specified length percentages is 40.37%. | Saleh, Suleiman; Sohn, Chang-Hyun | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | 59170922100; 36806852600 | suleiman@knu.ac.kr;chsohn@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 17 | 12 | SCIE | ENERGY & FUELS | 2024 | 3.2 | 61.3 | 1.03 | 2025-05-07 | 4 | 4 | energy harvester; pitching motion; leading flap; oscillating flat plate; trailing flap | EXTRACTION PERFORMANCE; FLAPPING AIRFOIL; PITCHING MOTION; FOIL; PROFILE | energy harvester; leading flap; oscillating flat plate; pitching motion; trailing flap | Energy Harvester; Flat plate; Leading flap; Oscillating flat plate; Performance; Pitch angle; Pitching motion; Power output; Power- generations; Trailing flap; Energy harvesting | English | 2024 | 2024-06 | 10.3390/en17123010 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Power Extraction Performance by a Hybrid Non-Sinusoidal Pitching Motion of an Oscillating Energy Harvester | This study proposes a hybrid pitching motion for oscillating flat plates aimed at augmenting the energy extraction efficiency of an energy harvester. The proposed hybrid pitching motion, within the first half cycle, integrates a non-sinusoidal movement starting at t/T = 0 and progressing to t/T = 0.25, with a sinusoidal movement initiating after t/T > 0.25 and continuing to t/T = 0.5. The second half of the cycle is symmetric to the first half but in the opposite direction. The calculated results show that the proposed hybrid pitching motion outperforms both the sinusoidal and the non-sinusoidal motions. The hybrid pitching motion merges the merits of both the sinusoidal and non-sinusoidal motions to optimize pitch angle variation. This integration is pivotal for enhancing the overall power output performance of an oscillating energy harvester characterized by momentum change that enhances the orientation of the heaving movement, smoother motion transitions, and consistent energy harvesting. The power generation is obtained at wing pitch angles of 55 degrees, 65 degrees, 70 degrees, 75 degrees, and 80 degrees during a hybrid pitching motion. The proposed hybrid pitching motion, set at a pitch angle of 70 degrees, achieves a maximum power output that exceeds the oscillating flat plate using a sinusoidal pitching motion by 16.0% at the same angle. | Saleh, Suleiman; Sohn, Chang-Hyun | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | 59170922100; 36806852600 | suleiman.a.s.saleh@gmail.com;chsohn@knu.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 17 | 11 | SCIE | ENERGY & FUELS | 2024 | 3.2 | 61.3 | 1.03 | 2025-05-07 | 4 | 4 | energy harvester; pitching motion; hybrid motion; sinusoidal and non-sinusoidal motions; oscillating flat plate | PROFILE; AIRFOIL | energy harvester; hybrid motion; oscillating flat plate; pitching motion; sinusoidal and non-sinusoidal motions | Extraction; Energy Harvester; Flat plate; Hybrid motion; Non-sinusoidal; Oscillating flat plate; Performance; Pitch angle; Pitching motion; Power extraction; Sinusoidal and non-sinusoidal motion; Energy harvesting | English | 2024 | 2024-06 | 10.3390/en17112451 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Development of a Transient Analysis Platform of Near-Critical CO2 Thermodynamic Systems via an Enthalpy-Based Implicit Continuous Eulerian Approach | This work presents the development and validation of an enthalpy-based implicit continuous Eulerian (ICE) solver, termed the near-critical ICE solver (NICES), for the analysis of near-critical CO2 thermodynamic systems. Traditional approaches relying on pressure and temperature as main inputs for the analysis have limitations in handling CO2 near the critical point, which exhibits unique characteristics and frequent phase changes. To overcome these limitations, this study proposes using enthalpy as a more suitable mathematical modeling approach. The NICES methodology employs the homogeneous equilibrium model and the Span and Wagner equations of state for CO2. This solver demonstrates improved numerical stability and computational speed compared to explicit calculation methods, as validated by frictionless heated pipe scenarios involving phase transitions near the critical point. The enthalpy-based NICES platform can predict thermohydraulics, including multiphase flows, without requiring specialized two-phase flow models. | Son, Seongmin; Bae, Seong Jun | Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju 37224, South Korea; Korea Atom Energy Res Inst, Daejeon 34057, South Korea | Son, Seongmin/KHU-6666-2024 | 56681720100; 56218305700 | seongminson@knu.ac.kr;sjbae@kaeri.re.kr; | ENERGIES | ENERGIES | 1996-1073 | 17 | 5 | SCIE | ENERGY & FUELS | 2024 | 3.2 | 61.3 | 0 | 2025-05-07 | 0 | 0 | supercritical CO2; transcritical CO2; transient analysis; implicit continuous Eulerian | EQUATION-OF-STATE; CRITICAL-POINT; BEHAVIOR; CYCLE | implicit continuous Eulerian; supercritical CO<sub>2</sub>; transcritical CO<sub>2</sub>; transient analysis; transient analysis | Carbon dioxide; Enthalpy; Equations of state; Numerical methods; Phase transitions; Two phase flow; Eulerian; Eulerian approach; Implicit continuous eulerian; Phase Change; Pressure and temperature; Supercritical CO 2; Thermodynamic systems; Traditional approaches; Transcritical; Transcritical CO2; Transient analysis | English | 2024 | 2024-03 | 10.3390/en17051126 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The Stabilization of a Nonlinear Permanent-Magnet- Synchronous-Generator-Based Wind Energy Conversion System via Coupling-Memory-Sampled Data Control with a Membership-Function-Dependent H∞ Approach | This study presents the coupling-memory-sampled data control (CMSDC) design for the Takagi-Sugeno (T-S) fuzzy system that solves the stabilization issue of a surface-mounted permanent-magnet synchronous generator (PMSG)-based wind energy conversion system (WECS). A fuzzy CMSDC scheme that includes the sampled data control (SDC) and memory-sampled data control (MSDC) is designed by employing a Bernoulli distribution order. Meanwhile, the membership-function-dependent (MFD) H-infinity performance index is presented, mitigating the continuous-time fuzzy system's disturbances. Then, by using the Lyapunov-Krasovskii functional with the MFD H-infinity performance index, the data of the sampling pattern, and a constant signal transmission delay, sufficient conditions are derived. These sufficient conditions are linear matrix inequalities (LMIs), ensuring the global asymptotic stability of a PMSG-based WECS under the designed control technique. The proposed method is demonstrated by a numerical simulation implemented on the PMSG-based WECS. Finally, Rossler's system demonstrates the effectiveness and superiority of the proposed method. | Yesudhas, Anto Anbarasu; Lee, Seong Ryong; Jeong, Jae Hoon; Govindasami, Narayanan; Joo, Young Hoon | Kunsan Natl Univ, Sch IT Informat & Control Engn, 588 Daehak Ro, Gunsan Si 54150, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | ; Joo, Young Hoon/AAU-7285-2020; Lee, Seong Ryong/HDO-8039-2022; Jeong, Jae/K-6334-2015 | 57654063300; 57203597098; 57184734200; 59252602300; 7102315421 | yanbarasu94@gmail.com;srlee@kunsan.ac.kr;jh7129@kunsan.ac.kr;narayanantvu@gmail.com;yhjoo@kunsan.ac.kr; | ENERGIES | ENERGIES | 1996-1073 | 17 | 15 | SCIE | ENERGY & FUELS | 2024 | 3.2 | 61.3 | 0.68 | 2025-05-07 | 2 | 2 | permanent-magnet synchronous generator; linear matrix inequalities; coupling-memory-sampled data control; Takagi-Sugeno fuzzy system | SLIDING-MODE CONTROL; S FUZZY-SYSTEMS; STABILITY ANALYSIS; DESIGN; VEHICLE | coupling-memory-sampled data control; linear matrix inequalities; permanent-magnet synchronous generator; Takagi–Sugeno fuzzy system | Asymptotic stability; Continuous time systems; Electric machine control; Energy conversion; Fuzzy systems; Lyapunov functions; Membership functions; Numerical methods; Permanent magnets; Sampled data control systems; Stabilization; Synchronous generators; Wind power; Condition; Coupling-memory-sampled data control; Energy conversion systems; Linear matrix in equalities; Memberships function; Performance indices; Permanent magnet synchronous generator; Sampled-data control; Takagi Sugeno fuzzy systems; Wind energy conversion; Linear matrix inequalities | English | 2024 | 2024-08 | 10.3390/en17153746 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Article | Simulation of Optical Communication Technology Based on Wireless Sensor Networks in Museum VR Design | With the rapid development of virtual reality (VR) technology, the design and presentation of museum exhibitions are also undergoing changes. However, traditional VR technology has some limitations in terms of transmission speed and user experience, so new technologies need to be introduced to improve these issues. This study focuses on the perspective of optical communication to improve the problems existing in traditional VR technology. A wireless sensor network-based optical communication system is proposed, which utilizes fiber optic transmission to provide stable and high-speed data transmission. Using optical fiber as a transmission medium can effectively transmit a large amount of data with lower transmission delay and higher bandwidth, overcoming the problems of delay and lag caused by low data transmission speed in traditional VR technology. By utilizing the characteristics of optical communication, sensor nodes and VR devices are wirelessly connected. The sensor nodes are arranged in different areas of the museum and connected to the central server through fiber optics. VR devices establish wireless connections with sensor nodes, transmit data through optical signals, achieve high-speed data transmission, and provide more freedom of mobility and a more realistic interactive experience. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024. | Guo, Wei; Shen, Hua; Wang, Chengyu | Kyungpook National University College of Arts, Daegu, 41566, South Korea; University Sains Malaysia, School of Arts, Penang, 11800, Malaysia; Department of Global Convergence, National Kangwon University, Chuncheon, 24341, South Korea | 59176038900; 59176174500; 59176039900 | wang059624@163.com; | Mobile Networks and Applications | MOBILE NETW APPL | 1383-469X | 1572-8153 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 2 | 61.4 | 0 | 2025-04-16 | 0 | Museums; Optical communication technology; VR; Wireless sensor network | Data transfer; Light transmission; Optical fibers; Sensor nodes; High-speed data transmission; Network-based; Optical communication technologies; Optical communications systems; Technology-based; Transmission speed; Transmission users; Users' experiences; Virtual reality devices; Virtual reality technology; Virtual reality | English | Article in press | 2024 | 10.1007/s11036-024-02363-3 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Efficiency Analysis of BLDC Motor With Delta Connection According to Magnitude of Circulating Current | In a delta connection, most of the battery voltage is applied directly to the motor's phase terminals, resulting in a voltage that is root three times higher than in a wye connection. This characteristic makes delta connections suitable for low-voltage, high-speed systems. However, the presence of 3 n-th harmonic components in the phase back electromotive force (BEMF) of delta-connected motors can induce circulating currents that flow exclusively within the circuit. These circulating currents lead to additional Joule losses and degrade motor performance. This article analyzes the effect of circulating currents on motor efficiency according to different speeds and torques. The presented study models maintain a similar magnitude of the fundamental component of BEMF but differ in the magnitude of the third harmonic component. A six-step circuit was established to compare the currents, losses, and efficiencies of the study models using finite element analysis (FEA). The copper losses were categorized into those caused by the fundamental component of phase current and those caused by the circulating currents. Subsequently, the efficiencies of the study models were compared across different speed and torque ranges, accounting for the separated copper loss components and iron losses. The results show that the improved model achieves an efficiency that is more than 18% higher than that of the basic model in the low-speed and low-torque areas. Finally, the study models were manufactured and evaluated through testing. | Lee, Ho-Young; Cha, Kyoung-Soo; Kwon, Soon-O; Yoon, Seung-Young; Seok, Chang-Hoon; Lim, Myung-Seop | Korea Inst Ind Technol, Adv Mobil Syst Grp, Daegu 42994, South Korea; Hanyang Univ, Dept Automot Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 42994, South Korea | 57049871300; 57193837116; 12790778500; 57320197600; 57581239400; 56421264500 | myungseop@hanyang.ac.kr; | IEEE TRANSACTIONS ON MAGNETICS | IEEE T MAGN | 0018-9464 | 1941-0069 | 60 | 12 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2024 | 1.9 | 61.6 | 0.34 | 2025-05-07 | 1 | 1 | Harmonic analysis; Motors; Torque; Integrated circuit modeling; Copper; Mathematical models; Magnetic cores; Brushless dc motor; circulating current; copper loss; delta winding; efficiency; harmonic phase current; six-step circuit; surface mounted permanent magnet synchronous motor | Brushless dc motor; circulating current; copper loss; delta winding; efficiency; harmonic phase current; six-step circuit; surface mounted permanent magnet synchronous motor | AC motors; Brushless DC motors; Electric windings; Printed circuit motors; Stepping motors; Terminals (electric); Brushless DC-motors; Circulating current; Copper loss; Delta connection; Delta winding; Harmonic phase current; Harmonics component; Phase currents; Six-step circuit; Surface mounted permanent magnet synchronous motor; Permanent magnets | English | 2024 | 2024-12 | 10.1109/tmag.2024.3465879 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Acid Mediated In-Situ Catalytic Cleavage/Making of C=N Bonds in Bis-Hydrazone Uranyl Complexes: Exploration of Photophysical, Electrochemical, Dye Sorption Properties and DFT Studies | Two new uranium complexes [UO2L2(H2O)] (where L2=diacetyl bis-isonicotinoyl hydrazone) complex 1, and [UO2(L1)2] (where L1=diacetylmonoxime isonicotinoylhydrazone) complex 2, have been synthesized by precisely adjusting the pH values of the reaction system. Complex 1 was formed in an acidic ethanolic solution (pH=3) through an in-situ acid catalytic reaction of diacetylmonoxime isonicotinoylhydrazone and UO2(NO3)2.6H2O, while complex 2 was acquired in a neutral medium (pH=7) through self-assembly of two ligands and one uranium (VI) metal centre. Both complexes were thoroughly characterized by elemental analysis, UV-Visible spectroscopy, IR spectroscopy, NMR, TGA, cyclic voltammetry, and powder X-ray diffraction. The studies indicate that the bis-hydrazone in complex 1 is a dianionic tetradentate N2O2 donor, whereas in complex 2 it is a monoanionic tridendate N2O donor. The formation of complex 1 was further confirmed by a single-crystal X-ray diffraction study, which revealed the role of a water molecule in forming a pentagonal bipyramidal geometry of [UO2L2(H2O)]. Photophysical studies revealed that complexes 1 and 2 exhibited low band gap values of 2.07 and 2.12 eV, respectively, indicating their semiconducting nature. From the CV measurements, the higher negative potentials of the complexes 1 & 2 {1, -0.6 V and 2, -0.5 V vs. ferrocenium/ferrocene (Fc+/Fc)} in DMSO are assigned to the presence of {UO2}2+/{UO2}+ couple signifying their redox active nature. Dye adsorption studies show that both the complexes were able to remove 90 % of Methylene blue (MB) and Rhodamine B (RhB) from the solutions with the concentration of 10-5 M. The structural insights and electronic properties of Ligand HL1 and complex 1 were further explored by density functional theory (DFT) calculations. Two uranium complexes have been synthesized using diacetylmonoxime isonicotinoylhydrazone as a ligand. In this study, the formation of two different complexes has been observed under two different pH conditions. At neutral pH, a M(L12) type structure is formed by the association of two ligands with the metal. Whereas, in acidic medium (pH=3), the same ligand is found to be involved in the acid catalytic hydrolysis of C=N and formation of new C=N bond to result in a new type of ML2 complex. Photophysical, electrochemical, and dye sorption properties have been successfully explored. Structural optimization of the ligand and complex was carried out by density functional theory (DFT) calculations. image | Devi, Sarau; Nayak, Sampurna; Richard, Bartholomew; Ravindran, Reena; Salaria, Punam; Chatterjee, Aditi; Arivazhagan, C.; Garai., Abhijit; Reddy, M.

| ○ | ○ | Article | 7,10-Dihydroxy-8(E)-octadecenoic Acid Displays a Fungicidal Activity against Malassezia furfur | Microbial conversion of some natural unsaturated fatty acids can produce polyhydroxy fatty acids, giving them new properties, such as higher viscosity and reactivity. Pseudomonas aeruginosa has been intensively studied to produce a novel 7,10-dihydroxy-8( E)-octadecenoic acid (DOD) from oleic acid and natural vegetable oils containing oleic acid. Recently, the antibacterial activities of DOD against food-borne pathogenic bacteria were reported; however, the action of such antibacterial properties against eucaryotic cells remains poorly known. In this study, we determined the antifungal activities of DOD against Malassezia furfur KCCM 12679 quantitatively and qualitatively. The antifungal activity of DOD against M. furfur KCCM 12679 was approximately five times higher than that of ketoconazole, a commercial antifungal agent. The MIC90 value of DOD against M. furfur KCCM 12679 was 50 mu g/mL. In addition, we confirmed that the antifungal property of DOD was exerted through fungicidal activity. | Kim, Hak-Ryul; Kim, In-Hwan | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 702701, South Korea; Korea Univ, Grad Sch, Dept Integrated Biomed & Life Sci, Seoul, South Korea | 57191717289; 47161438300 | hakrkim@knu.ac.kr; | JOURNAL OF OLEO SCIENCE | J OLEO SCI | 1345-8957 | 1347-3352 | 73 | 2 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY | 2024 | 1.8 | 62.0 | 0 | 2025-05-07 | 0 | 0 | antifungal activity; 7,10-dihydroxy-8(E)-octadecenoic acid; bioconversion; Pseudomonas aeruginosa; Malassezia furfur; vegetable oil | FATTY-ACID; ANTIBACTERIAL ACTIVITY; MEDIUM-CHAIN; TRIOLEIN | 7,10-dihydroxy-8(E)-octadecenoic acid; antifungal activity; bioconversion; Malassezia furfur; Pseudomonas aeruginosa; vegetable oil | Anti-Bacterial Agents; Antifungal Agents; Malassezia; Microbial Sensitivity Tests; Oleic Acid; Oleic Acids; 7,10-dihydroxy-8-octadecenoic acid; antifungal agent; antiinfective agent; oleic acid; Malassezia; microbial sensitivity test | English | 2024 | 2024 | 10.5650/jos.ess23169 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Developmental roles of glomerular epithelial protein-1 in mice molar morphogenesis | Glomerular epithelial protein-1 (Glepp1), a R3 subtype family of receptor-type protein tyrosine phosphatases, plays important role in the activation of Src family kinases and regulates cellular processes such as cell proliferation, differentiation, and apoptosis. In this study, we firstly examined the functional evaluation of Glepp1 in tooth development and morphogenesis. The precise expression level and developmental function of Glepp1 were examined by RT-qPCR, in situ hybridization, and loss and gain of functional study using a range of in vitro organ cultivation methods. Expression of Glepp1 was detected in the developing tooth germs in cap and bell stage of tooth development. Knocking down Glepp1 at E13 for 2 days showed the altered expression levels of tooth development-related signaling molecules, including Bmps, Dspp, Fgf4, Lef1, and Shh. Moreover, transient knock down of Glepp1 revealed alterations in cellular physiology, examined by the localization patterns of Ki67 and E-cadherin. Similarly, knocking down of Glepp1 showed disrupted enamel rod and interrod formation in 3-week renal transplanted teeth. In addition, due to attrition of odontoblastic layers, the expression signals of Dspp and the localization of NESTIN were almost not detected after knock down of Glepp1; however, their expressions were increased after Glepp1 overexpression. Thus, our results suggested that Glepp1 plays modulating roles during odontogenesis by regulating the expression levels of signaling molecules and cellular events to achieve the proper structural formation of hard tissue matrices in mice molar development. | Neupane, Sanjiv; Aryal, Yam Prasad; Kwak, Hee-Jin; Lee, Sung-Gwon; Kim, Tae-Young; Pokharel, Elina; Kim, Ji-Youn; Kim, Jung-Hyeuk; Sohn, Wern-Joo; An, Seo-Young; An, Chang-Hyeon; Jung, Jae-Kwang; Ha, Jung-Hong; Yamamoto, Hitoshi; Cho, Sung-Won; Lee, Sanggyu; Lee, Youngkyun; Park, Kwang-Kyun; Min, Bong-Ki; Park, Chungoo; Kwon, Tae-Yub; Cho, Sung-Jin; Kim, Jae-Young | Kyungpook Natl Univ, Sch Dent, Dept Biochem, Daegu, South Korea; SUNY Stony Brook, Dept Biochem & Cell Biol, Stony Brook, NY USA; Chungbuk Natl Univ, Coll Nat Sci, Sch Biol Sci, Cheongju, South Korea; Chonnam Natl Univ, Sch Biol Sci & Technol, Gwangju, South Korea; Gachon Univ, Dept Dent Hyg, Incheon, South Korea; Daegu Haany Univ, Premajor Cosmet & Pharmaceut, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, Daegu, South Korea; Tokyo Dent Coll, Dept Histol & Dev Biol, Tokyo, Japan; Yonsei Univ, Dept Oral Biol, Div Anat & Dev Biol, Coll Dent, Seoul, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 Plus KNU Creat Biores Grp, Daegu, South Korea; Yonsei Univ, Coll Dent, Dept Oral Biol, Seoul, South Korea; Yeungnam Univ, Ctr Res Facil, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu, South Korea | Neupane, Sanjiv/I-3470-2018; Kwak, Hee-Jin/KIJ-6769-2024; Kim, Ji-Youn/A-5779-2017; CHO, Sung-Won/HDO-3680-2022 | 56183800400; 57202611163; 57204325089; 57194872606; 57208461628; 57220028220; 57157491000; 57224009473; 44161404800; 55258203200; 17134437600; 55970994400; 55549831900; 55725330600; 56456948900; 7601418915; 36062942200; 57214310459; 57211058922; 56060870500; 7202206084; 56401329000; 56812734700 | sjchobio@chungbuk.ac.kr;jykim91@knu.ac.kr; | CELL AND TISSUE RESEARCH | CELL TISSUE RES | 0302-766X | 1432-0878 | 395 | 1 | SCIE | CELL BIOLOGY | 2024 | 2.9 | 62.0 | 0.73 | 2025-04-16 | 1 | 1 | Signaling regulation; Odontogenesis; Glepp1; Morphogenesis; Hard tissue formation | TYROSINE-PHOSPHATASE; ENAMEL KNOT; EXPRESSION PATTERNS; SIGNALING CENTER; SONIC HEDGEHOG; TOOTH; RECEPTOR; PTPRO; SUGGEST; GROWTH | Glepp1; Hard tissue formation; Morphogenesis; Odontogenesis; Signaling regulation | fibroblast growth factor 4; Ki 67 antigen; lymphoid enhancer factor 1; small interfering RNA; sonic hedgehog protein; uvomorulin; adult; animal cell; animal experiment; animal tissue; Article; Bmps gene; controlled study; Dspp gene; E13 gene; Fgf4 gene; gene; gene expression level; gene expression regulation; gene knockdown; gene location; gene overexpression; Glepp1 gene; histogenesis; in situ hybridization; in vitro study; kidney transplantation; Lef1 gene; male; mouse; NESTIN gene; nonhuman; odontoblast; protein localization; real time polymerase chain reaction; Shh gene; tooth development; tooth germ | English | 2024 | 2024-01 | 10.1007/s00441-023-03841-y | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Evaluation of ventricular pacing suppression algorithms in dual chamber pacemaker: Results of "LEADER" study | Background: There is limited research on the intra-individual efficacy of ventricular pacing minimization algorithms developed by Biotronik-the Ventricular Pace Suppression algorithm (VpS) and the Intrinsic Rhythm Support plus algorithm (IRSplus) (BIOTRONIK SE & Co. KG, Berlin, Germany). We performed a randomized pilot trial that evaluated the efficacy of two algorithms in patients with symptomatic sinus node dysfunction (SND) who received a dual-chamber pacemaker. Methods: The trial was conducted in 11 tertiary hospitals in South Korea. The patients were randomized to either the VpS or IRSplus algorithm group after a 3-month period of fixed atrioventricular (AV) delay. The primary outcome was the ventricular pacing percentage (Vp%) at each follow-up visit. The secondary outcomes were the occurrence of heart failure (HF) and atrial fibrillation (AF) during the study period. Results: Data from 131 patients were analyzed. Initially, their average Vp% over 3 months with a fixed AV interval was 14.1 +/- 19.4%. Patients were randomly assigned to VpS and IRSplus groups, with 66 and 65 in each. Algorithms reduced average Vp% to 4.0 +/- 11.3% at 9 months and 6.7 +/- 14.9% at 15 months. These algorithms were more effective for patients with paced AV delay (PAVD) 300 ms. Both algorithms were equally effective in reducing Vp%. Clinical AF or HF hospitalization was not observed during the study period. Conclusion: The VpS and IRSplus algorithms are effective and safe in minimizing unnecessary ventricular pacing in patients with SND. | Hwang, Jongmin; Han, Seongwook; Park, Hyoung-Seob; Chung, Tae-Wan; Jung, Minsu; Park, Seung-Jung; Lee, Chan-Hee; Ahn, Jin Hee; Choi, Eue-Keun; Bae, Myung Hwan; Lee, Young Soo; Park, Sang Won; Lee, Dae In; Kim, Yoo-Ri; Ahn, Min-Soo; Shim, Jaemin | Keimyung Univ, Dongsan Hosp, Dept Internal Med, Div Cardiol, 1035 Dalgubeol Daero, Daegu 42601, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Heart Vasc & Stroke Inst,Dept Internal Med,Div Car, Seoul, South Korea; Yeungnam Univ, Med Ctr, Dept Internal Med, Div Cardiol, Daegu, South Korea; Pusan Natl Univ Hosp, Dept Internal Med, Div Cardiol, Pusan, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Div Cardiol, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Div Cardiol, Daegu, South Korea; Daegu Catholic Univ, Med Ctr, Dept Internal Med, Div Cardiol, Daegu, South Korea; Bucheon Sejong Hosp, Cardiovasc Ctr, Bucheon Si, South Korea; Korea Univ, Guro Hosp, Dept Cardiol, Dept Internal Med, Seoul, South Korea; Chonnam Natl Univ, Med Sch, Dept Internal Med, Div Cardiol, Gwangju, South Korea; Yonsei Univ, Wonju Coll Med, Dept Internal Med, Div Cardiol, Wonju, South Korea; Korea Univ, Med Ctr, Dept Internal Med, Div Cardiol, Seoul, South Korea | ; Park, Seung-Jung/AAT-8353-2020; Ahn, Jin/C-6122-2019; Kim, YooRi/GVR-9570-2022; Choi, Eue-Keun/J-5968-2014 | 57215648513; 7405944969; 36175197800; 57555625300; 59141873400; 58030836900; 36045642800; 56560475600; 35558194200; 36607356800; 56368143800; 59222322100; 55069196000; 55548807300; 23088120600; 12759857000 | swhan@dsmc.or.kr; | JOURNAL OF ARRHYTHMIA | J ARRYTHM | 1880-4276 | 1883-2148 | 40 | 4 | ESCI | CARDIAC & CARDIOVASCULAR SYSTEMS | 2024 | 1.7 | 62.0 | 0 | 2025-05-07 | 0 | 0 | atrioventricular hysteresis; fixed AV delay; mode-switch algorithm; sinus node dysfunction; unnecessary right ventricular pacing | ATRIAL-FIBRILLATION; REDUCTION; MODE | atrioventricular hysteresis; fixed AV delay; mode-switch algorithm; sinus node dysfunction; unnecessary right ventricular pacing | beta adrenergic receptor blocking agent; calcium channel blocking agent; algorithm; Article; atrial fibrillation; cerebrovascular accident; follow up; good clinical practice; heart atrium appendage; heart failure; heart infarction; heart ventricle contraction; hospitalization; human; hysteresis; major clinical study; receiver operating characteristic; sinus node disease; tertiary care center | English | 2024 | 2024-08 | 10.1002/joa3.13117 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | Signal-Guided Multitask Learning for Myocardial Infarction Classification Using Images of Electrocardiogram | Introduction: The diagnosis of myocardial infarction (MI) needs to be swift and accurate, but definitively diagnosing it based on the first test encountered in clinical practice, the electrocardiogram (ECG), is not an easy task. The purpose of the study was to develop a deep learning (DL) algorithm using multitask learning method to differentiate patients experiencing MI from those without coronary artery disease using image-based ECG data. Methods: A DL model was developed based on 11,227 ECG images. We developed a new ECG interpretation algorithm through signal-guided multitask learning, building on a previously published single-task algorithm. The utility of this model was evaluated by testing 51 physicians in interpreting ECGs with and without the assistance of the DL model. Results: The proposed model demonstrated superior performance, achieving 90.56% accuracy, 83.82% sensitivity, 93.02% specificity, 81.44% precision, and an F1 score of 82.61% in discriminating MI ECG. Overall, the median accuracy of ECG interpretation improved from 62% to 68% with the DL algorithm. Trainees and specialists in internal medicine experienced significant accuracy increases (60–66% for trainees, 72–80% for specialists). In the MI group, NSTEMI accuracy was notably lower than STEMI (33% vs. 80%, p < 0.001), but the DL algorithm improved interpretative capabilities in both NSTEMI and STEMI. Conclusions: Signal-guided multitask DL algorithm demonstrated superior performance compared with previous single-task algorithm. The DL algorithm supports the physicians’ decision discriminating MI ECGs from non-MI ECGs. The improvement was consistent in subgroups of STEMI and NSTEMI. © 2024 The Author(s) | Park, Bo Eun; Shon, Byungeun; Cho, Jungrae; Jung, Min-Su; Park, Jong Sung; Kim, Myeong Seop; Lee, Eunkyu; Choi, Hyohun; Park, Hyuk Kyoon; Park, Yoon Jung; Kim, Hong Nyun; Kim, Namkyun; Bae, Myung Hwan; Lee, Jang Hoon; Yang, Dong Heon; Park, Hun Sik; Cho, Yongkeun; Jeong, Sungmoon; Jang, Se Yong | Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Medical Informatics, Kyungpook National University, Daegu, South Korea, Research Center for Artificial Intelligence in Medicine, Kyungpook National University Hospital, Deagu, South Korea; Research Center for Artificial Intelligence in Medicine, Kyungpook National University Hospital, Deagu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea; School of Medicine, Kyungpook National University, Daegu, South Korea, Kyungpook National University, Chilgok Hospital, Daegu, South Korea; School of Medicine, Kyungpook National University, Daegu, South Korea, Kyungpook National University, Chilgok Hospital, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Internal Medicine, Kyungpook National University Hospital, Daegu, South Korea, School of Medicine, Kyungpook National University, Daegu, South Korea; Department of Medical Informatics, Kyungpook National University, Daegu, South Korea, Research Center for Artificial Intelligence in Medicine, Kyungpook National University Hospital, Deagu, South Korea; School of Medicine, Kyungpook National University, Daegu, South Korea, Kyungpook National University, Chilgok Hospital, Daegu, South Korea | 57201131446; 58635954000; 57205507149; 57813643300; 58363053000; 57371425600; 57722787900; 57723256300; 57221712499; 57216539556; 56706769800; 55887032700; 36607356800; 54581258000; 35277423400; 57198844106; 9249593500; 23100090400; 57207977889 | jeongsm00@gmail.com;seyongjang@knu.ac.kr; | Cardiology (Switzerland) | CARDIOLOGY | 0008-6312 | 1421-9751 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS | 2024 | 1.7 | 62.0 | 0 | 2025-05-07 | 1 | Artificial intelligence; Deep learning; Electrocardiogram; Myocardial infarction | English | Article in press | 2024 | 10.1159/000542399 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Endotracheal tube cuff rupture during anesthesia in 2 dogs | A 15-year-old intact male dachshund dog weighing 4.3 kg and a 5-year-old intact male mixed-breed dog weighing 13.6 kg were referred for examination because of paraparesis and facial paralysis, respectively. Magnetic resonance imaging (MRI) of the thoracolumbar region and brain was performed. The dogs were premedicated with IV butorphanol, 0.2 mg/kg body weight (BW) and midazolam, 0.2 mg/kg BW. Anesthesia was induced IV propofol, 4 to 5 mg/kg BW and maintained with sevoflurane in oxygen. The dachshund was orotracheally intubated with a 5.0-millimeter internal diameter endotracheal (ET) tube. During positioning in the MRI room, intermittent positive pressure ventilation (IPPV) was applied. The mixed-breed dog was orotracheally intubated with a 6.0-millimeter internal diameter ET tube. After inflation of the ET tube cuff, a leaking test was done applying positive pressure ventilation. In both dogs, a distinct "popping" sound was heard when positive pressure was applied, after which air leakage from the cuff was evident. Failure to inflate the pilot balloon led to suspicion of a ruptured cuff. Reintubation was completed, both dogs remained stable during anesthesia, and no postanesthetic complications were observed. Rupture of both cuffs, which was visually confirmed, was thought to be caused overinflation of the cuff, repeated sterilization of the ET tubes, and positive pressure ventilation. Repeated sterilization of ET tubes with ethylene oxide can alter the physical integrity of cuffs. Care should be taken not overinflate ET tube cuffs, especially when they have been repeatedly sterilized, as cuff rupture may result in failure to provide adequate IPPV. | Shin, Chi Won; Jang, Min | Univ Saskatchewan, Western Coll Vet Med, Dept Small Anim Clin Sci, 52 Campus Dr, Saskatoon, SK S7N 5B4, Canada; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Surg, Daegu 41566, South Korea | jangmin@knu.ac.kr; | CANADIAN VETERINARY JOURNAL-REVUE VETERINAIRE CANADIENNE | CAN VET J | 0008-5286 | 65 | 4 | SCIE | VETERINARY SCIENCES | 2024 | 1 | 62.1 | 0 | PRESSURE | English | 2024 | 2024-04 | 바로가기 | 바로가기 |
