| ○ | Article | A Case of Sensorineural Hearing Loss Caused by Neurosyphilis in Patient Who Is Treated by Anti-Interleukin 17A Monoclonal Antibody | Syphilis is a sexually transmitted disease caused by Treponema pallidum, which can invade various organs. Syphilis can also cause otologic symptoms such as hearing impairment, tinnitus or dizziness and these otologic symptoms can occur at any stage of syphilis and can be associated with neurosyphilis. We report here a case of rapid progressive neurosyphilis showing hearing impairment in a patient with ankylosing spondylitis. He was treated with anti-interleukin 17A monoclonal antibody. Since syphilis is one of the causes of reversible sensorineural hearing loss and syphilis infection with immunosuppression can cause progressive hearing loss if patients in immunomodulatory therapy have sensorineural hearing loss, the possibility of syphilis should be considered.

| ○ | Article | A Case Study of Digital Transformation: Focusing on the Financial Sector in South Korea and Overseas | This study investigates the adoption and application of digital transformation in the financial sector and analyzes the process and outcomes of digitization and digitalization in the field of the finance industry of South Korea and overseas, in order to seek both managerial and strategic implications for successful implementation of digital transformation in the future. The findings show that, for successful digital transformation, it is necessary to maximize active and systematic use of advanced online and digital technologies that form the basis of business and create an open, horizontal organizational culture and communication system to equally share and distribute advanced technologies and competencies through the entire organization. Furthermore, this study also discovers the legitimacy to concentrate the organizational competencies and know-how in providing technical training for members, expanding customer experience, and improving customer satisfaction services to contribute to improving the quality of life for members of the organization and creating and improving social and public infrastructures, instead of using digital transformation only to improve productivity of organizations or firms. As such, it is necessary to concentrate corporate competencies in establishing and supplying digital transformation that is not just human-centered but also has productivity, innovativeness, and reliability at the same time. © 2022,Asia Pacific Journal of Information Systems.

| ○ | ○ | Proceedings Paper | A Compact Printed Dual-Band (915MHz/2.4GHz) Folded Monopole Antenna | A compact printed dual-band folded monopole antenna has been proposed for the operation at 915MHz and 2.4GHz ISM bands. The dual resonance operation from a monopole antenna with a total length lesser than 0.2.915MHz including a finite ground plane occupying 1/6th of the total antenna space is the main feature of the proposed antenna. Furthermore, the easier integration of the proposed dual-band antenna on the printed circuit board without using its ground plane is another important characteristic. The desired dual resonances were obtained by implementing a folded conductor pattern for the antenna's main radiator along with two rectangular conductor stubs deployed at different positions along the main radiator on a 60 x 20 x 1mm(3) FR4 substrate. The 915MHz resonance was caused by the folded conductor pattern of the main radiator with a stub located at its end while a shorter conductor segment was defined on the main radiator by placing the second rectangular stub at about 0.25 lambda(2.4GHz) caused the other resonance at 2.4GHz. The design of the proposed dual-band antenna was simulated and analyzed in ANSYS HFSS. The simulated return loss of about -18dB at both frequencies along with a peak realized gain of 3.2dB and 2.3dB were obtained at 915MHz and 2.4GHz respectively. | Sheikh, Faisal Ahmad; Kim, Young Cheol; Choi, Ickchang; Kim, Hyun Deok | Kyungpook Natl Univ, Inst Adv Convergence Technol, 70 Dongnae Ro, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu, South Korea | Kim, Yong Joon/IQS-7291-2023 | 37074158500; 57218240460; 37074258500; 55663858300 | faisalthestar@knu.ac.kr;yckim@knu.ac.kr;choic@iact.or.kr;hdkim@knu.ac.kr; | 2022 IEEE INTERNATIONAL RF AND MICROWAVE CONFERENCE, RFM | 2472-1549 | 0 | 2025-06-25 | 0 | 0 | folded monopole antenna; PCB antenna; dual-band antenna; finite ground plane; 915MHz; 2.4GHz; ISM band | 2.4GHz; 915MHz; dual-band antenna; finite ground plane; folded monopole antenna; ISM band; PCB antenna | Antenna grounds; Directional patterns (antenna); Microstrip antennas; Monopole antennas; Printed circuit boards; Slot antennas; 2.4ghz; 915mhz; Conductor patterns; Dual Band; Dual band antennas; Dual resonance; Finite ground plane; Folded monopole antenna; ISM bands; PCB antenna; Radiators | English | 2022 | 2022 | 10.1109/rfm56185.2022.10064838 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article; Proceedings Paper | A Comprehensive Empirical Study of Query Performance Across GPU DBMSes | In recent years, GPU database management systems (DBMSes) have rapidly become popular largely due to their remarkable acceleration capability obtained through extreme parallelism in query evaluations. However, there has been relatively little study on the characteristics of these GPU DBMSes for a better understanding of their query performance in various contexts. Also, little has been known about what the potential factors could be that affect the query processing jobs within the GPU DBMSes. To fill this gap, we have conducted a study to identify such factors and to propose a structural causal model, including key factors and their relationships, to explicate the variances of the query execution times on the GPU DBMSes. We have also established a set of hypotheses drawn from the model that explained the performance characteristics. To test the model, we have designed and run comprehensive experiments and conducted in-depth statistical analyses on the obtained empirical data. As a result, our model achieves about 77% amount of variance explained on the query time and indicates that reducing kernel time and data transfer time are the key factors to improve the query time. Also, our results show that the studied systems should resolve several concerns such as bounded processing within GPU memory, lack of rich query evaluation operators, limited scalability, and GPU under-utilization. | Suh, Young-Kyoon; An, Junyoung; Tak, Byungchul; Na, Gap-Joo | Kyungpook Natl Univ, Sch Comp Sci & Engn, Dept Data Convergence Comp, Daegu, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Elect & Telecommun Res Inst, Artificial Intelligence Res Lab, Daejeon, South Korea | 55443739900; 57224010954; 6506911621; 13103777300 | yksuh@knu.ac.kr;jyan@knu.ac.kr;bctak@knu.ac.kr;funkygap@etri.re.kr; | PROCEEDINGS OF THE ACM ON MEASUREMENT AND ANALYSIS OF COMPUTING SYSTEMS | P ACM MEAS ANAL COMP | 2476-1249 | 6 | 1 | ESCI | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2022 | 1.7 | 1.16 | 2025-06-25 | 1 | 4 | GPU DBMS; query time; causal model; performance evaluation | Causal model; Gpu dbms; Performance evaluation; Query time | Data transfer; Database systems; Program processors; Query processing; Acceleration capabilities; Causal modeling; Empirical studies; Gpu dbms; Key factors; Performances evaluation; Processing jobs; Query evaluation; Query performance; Query time; Graphics processing unit | English | 2022 | 2022-03 | 10.1145/3508024 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||

| ○ | Article | A Conceptual Study on Photodynamic Control-Mediated Holographic Composites | Herein, photodynamic control-mediated holographic composites are proposed, which are composed of photosensitizers, singlet oxygen receptors, and a polymeric matrix. Rose bengal (RB) and methylene blue (MB) are used as photosensitizers, and 1,3-diphenylisobenzofuran (DPBF) as a singlet oxygen receptor. First, the photodynamic effects of the photosensitizers in DPBF-dissolved solutions are evaluated by analyzing the optical properties of DPBF under laser irradiation. The results confirm that RB and MB are selectively photoexcited by a green and red laser, respectively, and DPBF only reacts to the photosensitized singlet oxygen. Similarly, an outstanding photodynamic effect is observed in the DPBF-coated photodynamic films upon 660 nm laser irradiation. To evaluate the holographic performances of the films, the diffraction efficiency of the films is measured under the beams. The diffraction efficiency of the films is 2.03%. The results suggest that the conformational changes of the receptor are accompanied with absorptive gradients on the films. Therefore, it is strongly believed that the new strategy with photodynamic control can provide appealing solutions in the near future for holographic applications. | Lee, Yewon; Kim, Hyeong Seok; Kang, Yi Young; Kang, Hye Ju; Lee, Jieun; Kim, Jawon; Lee, Jae-Won; Lee, Su-Won; Min, Seungah; Koh, Won-Gun; Kang, Youngjong; Kim, Hak-Rin; Ka, Jae-Won | Korea Res Inst Chem Technol, Adv Polymer Mat Res Ctr, 141 Gajeong Ro, Daejeon 34114, South Korea; Yonsei Univ, Dept Chem & Biomol Engn, 50 Yonsei Ro, Seoul 03722, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Hanyang Univ, Dept Chem, 222 Wangsimni Ro, Seoul 04763, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Kim, Hak-Rin/T-1897-2019; Jang, Woo-Dong/I-7186-2019 | jwka@krict.re.kr; | ADVANCED PHOTONICS RESEARCH | ADV PHOTON RES | 2699-9293 | 3 | 8 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY;OPTICS | 2022 | 3.7 | 1 | holographic recordings; photodynamic effects; photodynamic films; photosensitizers; singlet oxygen receptors | SINGLET OXYGEN; DICHROMATED GELATIN; EFFICIENCY; GRATINGS | English | 2022 | 2022-08 | 10.1002/adpr.202100363 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Conference paper | A Convenient Implementation of the Ternary Logic: Using Anti-Ambipolar Transistors and PMOS Based on Printed Carbon Nanotubes | Ternary logic is said to become the potential solution to overcome the issues we encounter in binary systems. To enlighten this potential, we propose a ternary logic based on novel Anti-ambipolar transistors (AATs) and PMOSs. Conventional AATs require a complex fabrication process, and their operation is beyond the range of typical CMOS (>5 V). However, Inkjet-printed AATs are easy to fabricate, and their operating voltage is under 2V. Thus, Inkjet-based AATs are highly-suitable to use with other printable devices. Therefore, in this paper, we propose a set of novel ternary logic based on printed AATs and carbon-nanotube PMOSs. With these AATs and PMOSs, we propose 10 novel logic gates that include a practical balanced ternary full adder (TFA). Our TFA presents a compact design that can be implemented only with 41 PMOSs and 17 AATs. Our TFA reduces transistor count by -22.6% compared to the latest TFA design. We highlight that our ternary logic cells based on AATs and PMOSs are 1) the most compact design in terms of transistor count and 2) very convenient to fabricate. © 2022 IEEE. | Kim, Jongbeom; Kim, Yeji; Lee, Hyundong; Yun, Jihyeong; Jang, Hyeseung; Jin, Huijeen; Park, Juhee; Kim, Bongjun; Song, Taigon | School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Sookmyung Women's University, Department of Electronics Engineering, Seoul, 04312, South Korea; Sookmyung Women's University, Department of Electronics Engineering, Seoul, 04312, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea, School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea | 57782068500; 57781806700; 57226892881; 57781016500; 57782068400; 57780756800; 57684576100; 56125116600; 36005021000 | Proceedings of The International Symposium on Multiple-Valued Logic | 0195-623X | 2022-May | 1.15 | 2025-06-25 | 3 | Anti-ambipolar Transistor (AAT); ternary full-adder; ternary logic | Adders; Computer circuits; Logic devices; Transistors; Ambipolar transistors; Anti-ambipolar transistor; Binary systems; Compact designs; Fabrication process; Full adders; Ink jet; Ternary full-adder; Ternary logic; Transistor count; Carbon nanotubes | English | Final | 2022 | 10.1109/ismvl52857.2022.00010 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Proceedings Paper | A DQN-based CUBIC for TCP Congestion Control | In a static environment, as the available bandwidth increases, the slow congestion window increase rate prevents the existing TCP fully utilizing the bandwidth. CUBIC, a congestion control algorithm for high-speed networks, can provide higher throughput than existing algorithms but cannot guarantee satisfactory performance during frequent bandwidth fluctuations. Applying Deep-Q-Network to a TCP congestion control algorithm can improve link utilization. Therefore, in this paper, we propose a DQN-based CUBIC for various networks environments, which simultaneously utilizes the mechanisms of CUBIC and DQN. Through simulation experiments based on NS-3, it was confirmed that the proposed algorithm can increase the throughput compared to CUBIC in any link environment. | Seo, Sang-Jin; Kim, Geon-Hwan; Cho, You-Ze | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57563304000; 57189040274; 7404469829 | chil258@knu.ac.kr;kgh76@ee.knu.ac.kr;yzcho@ee.knu.ac.kr; | 2022 27TH ASIA PACIFIC CONFERENCE ON COMMUNICATIONS (APCC 2022): CREATING INNOVATIVE COMMUNICATION TECHNOLOGIES FOR POST-PANDEMIC ERA | 2163-0771 | 2.29 | 2025-06-25 | 1 | 6 | Deep Q Network; TCP congestion control | Deep Q Network; TCP congestion control | Bandwidth; Transmission control protocol; Available bandwidth; Bandwidth fluctuations; Congestion control algorithm; Deep Q network; High-speed Networks; High-throughput; Performance; Static environment; TCP congestion control; TCP congestion control algorithm; HIgh speed networks | English | 2022 | 2022 | 10.1109/apcc55198.2022.9943650 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Conference paper | A fire detection scheme using 5G network-based KNN algorithm | As fire accidents cause large-scale human and material damage, it is necessary to have an active and active response system using information and communications technology. Recently, technologies are being researched using advanced information technology to efficiently respond to various fire situations. It analyzes the data and uses it to recognize the fire situation. However, most of the fire detection uses deep learning technology to detect the shape of a flame using image technology and respond to it. This is the situation. Therefore, in this paper, we apply the KNN(K Nearest Neighbors) machine learning algorithm technique for multi-sensor-based fire/non-fire classification and use 5G communication network technology for real-time response to increase the fire detection hit rate and propose a technology suitable for service supply in large-scale complexes. © 2022 IEEE. | Yoon, Mahnsuk; Lee, Changkyo; Lim, Gilhwan; Choi, Hyunchul; Cho, Kyucheol | Geri (Gumi Electronics & Information Technology Research Institute), Future Mobile Communication Research Center, Gumi, South Korea; Geri (Gumi Electronics & Information Technology Research Institute), Future Mobile Communication Research Center, Gumi, South Korea; Research Institute Daon Co., Ltd., Gumi, South Korea; Research Institute Daon Co., Ltd., Gumi, South Korea; School of Computer Secience and Engineering, Kyungpook National University, Software Education Center, Daegu, South Korea | 57203640624; 57189091503; 57991627800; 57991627900; 26031217700 | International Conference on ICT Convergence | 2162-1233 | 2022-October | 0.22 | 2025-06-25 | 1 | 5G(5th Generation) Network; Fire detection algorithm; Machine Learning; Multi Sensor | 5G mobile communication systems; Deep learning; Information use; Learning algorithms; Learning systems; Nearest neighbor search; Population statistics; Queueing networks; Signal detection; 5th generation network; Detection scheme; Fire accident; Fire detection; Fire detection algorithms; Large-scales; Machine-learning; Multi sensor; Nearest-neighbor algorithms; Network-based; Fires | English | Final | 2022 | 10.1109/ictc55196.2022.9952851 | 바로가기 | 바로가기 | |||||||||||||||||

| ○ | ○ | Article | A guideline for the statistical analysis of compositional data in immunology | The study of immune cellular composition has been of great scientific interest in immunology because of the generation of multiple large-scale data. From the statistical point of view, such immune cellular data should be treated as compositional. In compositional data, each element is positive, and all the elements sum to a constant, which can be set to one in general. Standard statistical methods are not directly applicable for the analysis of compositional data because they do not appropriately handle correlations between the compositional elements. In this paper, we review statistical methods for compositional data analysis and illustrate them in the context of immunology. Specifically, we focus on regression analyses using log-ratio transformations and the alternative approach using Dirichlet regression analysis, discuss their theoretical foundations, and illustrate their applications with immune cellular fraction data generated from colorectal cancer patients. | Yoo, Jinkyung; Sun, Zequn; Greenacre, Michael; Ma, Qin; Chung, Dongjun; Kim, Young Min | Kyungpook Natl Univ, Dept Stat, Daegu 41566, South Korea; Northwestern Univ, Dept Prevent Med Biostat, Evanston, IL USA; Univ Pompeu Fabra, Dept Econ & Business, Barcelona, Spain; Barcelona Sch Management, Barcelona, Spain; Ohio State Univ, Dept Biomed Informat, Columbus, OH 43210 USA | Ma, Qin/AAI-3810-2021; Chung, Dongjun/AAI-6032-2020 | 57425952600; 57201190382; 26643069000; 36843466800; 23992248900; 56035273800 | chung.911@osu.edu;kymmyself@knu.ac.kr; | COMMUNICATIONS FOR STATISTICAL APPLICATIONS AND METHODS | COMMUN STAT APPL MET | 2287-7843 | 2383-4757 | 29 | 4 | ESCI | STATISTICS & PROBABILITY | 2022 | 0.4 | 0.83 | 2025-06-25 | 6 | 6 | compositional data; compositional regression; Dirichlet regression; immunology; immuno-oncology; log-ratio transformation | REGRESSION; SELECTION; TESTS | Compositional data; Compositional regression; Dirichlet regression; Immuno-oncology; Immunology; Log-ratio transformation | English | 2022 | 2022-07 | 10.29220/csam.2022.29.4.453 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | A high-speed driver behavior detection deep learning system using the amount of change in contrast between frames | This paper proposes a deep learning system that detects driver behavior for safe driving. A method of detecting the dangerous behavior of an existing driver uses a method of deep learning object detection that detects a class and a location of an object in an image. However, the deep learning object detection algorithm uses many computational resources, so it cannot be used in vehicle embedded environments with limited computational resources. In the case of an object classification algorithm that classifies a single object in an image, fewer computational resources are used than that of a deep learning object detection algorithm. However, it cannot be applied because various objects in the camera image cannot be classified as a single object. In the paper, We propose an algorithm that infers the driver's behavioral area using the driver's static movement in a vehicle and then applies deep learning objects to the inferred area. The proposed algorithm may be applied to a vehicle embedded environment because the calculation time is faster and more accurate than the deep learning object detection algorithm. © 2022 IEEE. | Yoo, Min Woo; Kim, Jihun; Cha, Dae Woong; Son, Woo Sung; Lee, Donggyu; Han, Dong Seog | Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea | 57216618843; 56024681400; 57202576121; 57223306362; 57169003900; 7403219442 | dshan@knu.ac.kr; | 4th International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2022 - Proceedings | 0.27 | 2025-06-25 | 1 | classification; deep learning; object detection | Deep learning; Learning algorithms; Object detection; Object recognition; Signal detection; Behavior detection; Computational resources; Deep learning; Driver's behavior; Embedded environment; High speed driver; Object classification; Object detection algorithms; Safe driving; Single object; Vehicles | English | Final | 2022 | 10.1109/icaiic54071.2022.9722670 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | A High-Throughput and Energy-Efficient SHA-256 Design using Approximate Arithmetic | This paper presents a novel high-throughput SHA-256 design exploiting approximate computing. The 32-bit addition of the SHA-256 architecture consumes a lot of hardware resources, hence we suggest a split k-bit adder-based SHA-256 design to significantly reduce hardware resources while ensuring acceptable hash functionality. The proposed designs enhance the area, delay, and energy when employed with 28-nm CMOS technology by 8.9%, 45.7%, and 9.3% in the 2-bit configuration and 15%, 52.9%, and 11.3% in the 1-bit configuration, respectively, compared to the conventional SHA-256 design. Additionally, the proposed designs improve the area-delay product (ADP), energy-delay product (EDP), and throughput performances by at least 19.1%, 20.2%, and 18.6% with a maximum of 149.8%, 139.3%, and 112.1%, respectively, compared to the traditional design. Additionally, all of the proposed designs obtain a higher average of Avalanche effect than the traditional ones, and all the message digests generated by the proposed SHA-256 are randomly distributed. © 2022 Institute of Electronics and Information Engineers.

It is estimated that currently about 62 million hectares or 20 percent of the world’s irrigated land is affected by salinity. Salinity is a serious problem in the coastal areas of Bangladesh. Isolation of salt-tolerant plant growth-promoting bacteria (PGPB) and applying them as bioinoculants in crop plants are considered promising and effective biotechnological approaches to combat soil salinity. This study aimed to screen salt-tolerant PGPB from the root, leaf, and rhizospheric soils of rice plants collected from salt-affected coastal areas including Chattogram, Noakhali, Lakshmipur, and Cox’s Bazar districts of Bangladesh and evaluated their performances on the seedling growth of rice. Out of forty-one salinity-tolerant bacterial isolates screened, Brevibacterium sediminis showed salinity tolerance up to 12% NaCl (w/v). In vitro bioassay revealed that B. sediminis promoted the seedling growth of rice cv. BRRI dhan29 (salinity susceptible) and BINAdhan-10 (salinity tolerant), and the growth-promoting effects were higher in BINAdhan-10. This study for the first time identified B. sediminis strain IBGE3C as a salt-tolerant PGPB from a widely cultivated rice variety, BRRI dhan28 in the Lakshmipur district of Bangladesh. Our results suggest that salt-tolerant PGPB isolated from the root, leaf, and rhizospheric soil of rice plants could be used as a low cost and environmentally friendly option for overcoming the detrimental effects of salt stress on rice plants in the southern coastal regions of Bangladesh. However, further studies are needed for assessing the efficacy of B. sediminis on enhancement of salinity tolerance, and growth and yield of rice under salinity stressed conditions. © 2022 by the authors. | Mahmud-Ur-Rahman; Naser, Iftekhar Bin; Mahmud, Nur Uddin; Sarker, Aniruddha; Hoque, M.

| ○ | Review | A Limited Angle Torque Motor Hybrid Structure to Improve Torque Density | The limited angle torque motor (LATM) is an electromagnetic actuator that rotates within a limited angle of less than ±90°. In this study, the advantages of permanent magnet (PM) type and reluctance type LATM are combined to create a hybrid LATM with high torque density for the same volume. The proposed hybrid LATM structure combines structural advantages using a PM with a high magnetic flux density of a PM type LATM and voice coil winding with a high fill factor of reluctance type, as well as making a prototype and conducting a torque test. © The Korean Institute of Electrical Engineers. | Shin, Jin-Yeong; Kwon, Soon-O; Lee, Ho-Young; Lee, Gi-Ju; Yoon, Seung-Young; Choi, Hong-Soon | School of Electronic and Electrical Engineering, Kyungpook National University, South Korea; Advanced Mechatronics R&D Group, Korea Institute of Industrial Technology, South Korea; Advanced Mechatronics R&D Group, Korea Institute of Industrial Technology, South Korea; Advanced Mechatronics R&D Group, Korea Institute of Industrial Technology, South Korea; Advanced Mechatronics R&D Group, Korea Institute of Industrial Technology, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, South Korea | 57320197700; 12790778500; 57049871300; 57212469872; 57320197600; 7404338767 | tochs@knu.ac.kr; | Transactions of the Korean Institute of Electrical Engineers | 1975-8359 | 71 | 2 | 0 | 2025-06-25 | 0 | LAT motor; LATM; torque actuator; torque density; torque motor; voice coil | Magnetic actuators; Permanent magnets; Electromagnetic actuators; High magnetic flux density; High torque density; Hybrid structure; LAT motor; Limited angle torque motors; Structural advantage; Torque actuators; Torque density; Voice coil; Torque | Korean | Final | 2022 | 10.5370/kiee.2022.71.2.359 | 바로가기 | 바로가기 |
