| ○ | ○ | Article | TonEBP Haploinsufficiency Attenuates Microglial Activation and Memory Deficits in Middle-Aged and Amyloid β Oligomer-Treated Mice | Age-related microglial activation is associated with cognitive impairment. Tonicity-responsive enhancer-binding protein (TonEBP) is a critical mediator of microglial activation in response to neuroinflammation. However, the precise role of TonEBP in the middle-aged brain is not yet known. We used TonEBP haploinsufficient mice to investigate the role of TonEBP in middle-aged or amyloid beta oligomer (A beta O)-injected brains and examined the effect of TonEBP knockdown on A beta O-treated BV2 microglial cells. Consistent with an increase in microglial activation with aging, hippocampal TonEBP expression levels were increased in middle-aged (12-month-old) and old (24-month-old) mice compared with young (6-month-old) mice. Middle-aged TonEBP haploinsufficient mice showed reduced microglial activation and fewer memory deficits than wild-type mice. Electron microscopy revealed that synaptic pruning by microglial processes was reduced by TonEBP haploinsufficiency. TonEBP haploinsufficiency also reduced dendritic spine loss and improved memory deficits in A beta O-treated mice. Furthermore, TonEBP knockdown attenuated migration and phagocytosis in A beta O-treated BV2 cells. These findings suggest that TonEBP plays important roles in age-related microglial activation and memory deficits. | Lee, Jong Youl; Jeong, Eun Ae; Lee, Jaewoong; Shin, Hyun Joo; Lee, So Jeong; An, Hyeong Seok; Kim, Kyung Eun; Kim, Won-Ho; Bae, Yong Chul; Kang, Heeyoung; Roh, Gu Seob | Gyeongsang Natl Univ, Inst Hlth Sci, Coll Med, Dept Anat & Convergence Med Sci, Jinju 52727, South Korea; Korea Natl Inst Hlth, Dept Chron Dis Convergence Res, Div Cardiovasc Dis Res, Cheongju 28159, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Anat & Neurobiol, Daegu 41944, South Korea; Gyeongsang Natl Univ, Gyeongsang Natl Univ Hosp, Coll Med, Dept Neurol, Jinju 52727, South Korea | Kim, Won Ho/S-8671-2019 | 57189499180; 36523091200; 57219269408; 16047897100; 57789444600; 57204728609; 59650264600; 57218216594; 56377838800; 56549268500; 6603224998 | jyv7874v@naver.com;jeasky44@naver.com;woongs1111@gmail.com;k4900@hanmail.net;thwjd5411@naver.com;gudtjr5287@hanmail.net;kke-jws@hanmail.net;jhkwh@nih.go.kr;ycbae@knu.ac.kr;miranda75@naver.com;anaroh@gnu.ac.kr; | CELLS | CELLS-BASEL | 2073-4409 | 12 | 22 | SCIE | CELL BIOLOGY | 2023 | 5.1 | 30.5 | 0 | 2025-06-25 | 0 | 0 | TonEBP; microglia; hippocampus; aging; amyloid beta | ENHANCER-BINDING PROTEIN; A-BETA; MEDIATED NEUROINFLAMMATION; ALZHEIMERS-DISEASE; TREM2; EXPRESSION; PHAGOCYTOSIS; SPINES | aging; amyloid beta; hippocampus; microglia; TonEBP | Amyloid beta-Peptides; Animals; Haploinsufficiency; Memory Disorders; Mice; Microglia; NFATC Transcription Factors; allograft inflammatory factor 1; amyloid beta protein; cyclooxygenase 2; inducible nitric oxide synthase; interleukin 10; interleukin 6; nucleic acid binding protein; oligomer; tiletamine plus zolazepam; tonicity responsive enhancer binding protein; transforming growth factor beta1; triggering receptor expressed on myeloid cells 2; tumor necrosis factor; unclassified drug; xylazine; amyloid beta protein; transcription factor NFAT; adult; aged; aging; animal cell; animal experiment; animal model; animal tissue; Article; atrophy; BV-2 cell line; cell activation; cell migration; cognition; cognitive defect; confocal microscopy; controlled study; dendritic spine; electron microscopy; experimental behavioral test; gene expression; haploinsufficiency; hippocampal CA1 region; hippocampus; human; image analysis; immunofluorescence; immunohistochemistry; inflammation; memory disorder; microglia; middle aged; morphology; Morris water maze test; mouse; nervous system inflammation; nonhuman; novel object recognition test; open field test; phagocytosis; real time reverse transcription polymerase chain reaction; spatial memory; synapse; telomere length; transmission electron microscopy; transwell assay; Western blotting; Y-maze test; animal; haploinsufficiency; memory disorder; metabolism; microglia | English | 2023 | 2023-11 | 10.3390/cells12222612 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Removal of Fe from Ilmenite Ore Powders Through Selective Chlorination Using CO and Cl2 Gas Mixture at 1073-1173 K in a Static Bed | To develop a selective chlorination process for ilmenite ores with the aim of attaining a high chlorination ratio of Fe and minimal Ti loss with low activation energy, the kinetics of the selective chlorination of Fe from ilmenite ore powders using a mixture of CO and Cl-2 gases in a static bed reactor was investigated. Experiments were conducted using ilmenite ore powders in the ranges of 45-75 mu m and 180-212 mu m at 1073-1173 K. When the chlorination reactions proceeded at 1173 K for 60 min, 94.12% of the Fe and 2.18% of the Ti were removed from the ore. After the selective chlorination reactions, TiO2 with a porous microstructure was generated owing to the selective removal of Fe from the ore. The generated pores allowed the CO-Cl-2 gas mixture to easily penetrate into the reaction interface. As a result, when the unreacted shrinking-core model was utilized, the rate-controlling step was chemical reaction at the interface. In addition, the activation energy was 49.879 kJ & BULL; mol(-1) for the selective chlorination of ilmenite ore powders using the CO-Cl-2 gas mixture at 1073-1173 K. The results demonstrate that minimal Ti loss and a high chlorination ratio of Fe are feasible when the selective chlorination of ilmenite ore powders is performed at 1173 K using a CO-Cl-2 gas mixture in a static bed reactor. | Park, Sung-Hun; Lee, So-Yeong; Ring, Rie; Kang, Jungshin; Sohn, Ho-Sang | Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, 124 Gwahak Ro, Daejeon 34132, South Korea; Hyundai MOBIS China R&D Ctr, Steering Control Design Dept, 1011 Jiujing Rd, Shanghai 201615, Peoples R China; Pusan Natl Univ, Sch Mat Sci & Engn, 2 Busandaehak Ro 63beon Gil, Busan 46241, South Korea | Park, Sung-Hun/JZS-8726-2024 | 57208205988; 57208210267; 58003276700; 55637737500; 7201426373 | psh0820@knu.ac.kr;soiltank123@knu.ac.kr;linglie@gmobis.com;jkang@pusan.ac.kr;sohn@knu.ac.kr; | JOURNAL OF SUSTAINABLE METALLURGY | J SUSTAIN METALL | 2199-3823 | 2199-3831 | 9 | 1 | SCIE | GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY;METALLURGY & METALLURGICAL ENGINEERING | 2023 | 2.5 | 30.6 | 0.14 | 2025-06-25 | 1 | 1 | Ilmenite; Selective chlorination; Synthetic rutile; Kinetics; Activation energy | TITANIUM ORE; IRON; KINETICS; BENEFICIATION | Activation energy; Ilmenite; Kinetics; Selective chlorination; Synthetic rutile | Activation energy; Chlorination; Chlorine compounds; Gas mixtures; Iron; Phase interfaces; Powders; Titanium dioxide; Chlorination process; Chlorination reactions; Gases mixture; Low-activation energy; Porous microstructure; Selective chlorination; Selective removal; Static-bed reactors; Static-beds; Synthetic rutile; Ilmenite | English | 2023 | 2023-03 | 10.1007/s40831-022-00628-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Scale-Up Study of Deoxidation of Off-Grade Titanium Sponge Using Magnesium Metal Under Argon and Hydrogen Mixed Gas Atmosphere | To develop an efficient and cost-effective process for recycling off-grade titanium (Ti) sponge, the scale-up study of deoxidation of off-grade Ti sponge using magnesium (Mg) metal under argon (Ar) and hydrogen (H-2) mixed gas was conducted. In the experiments, titanium hydride (TiH2) produced by the hydrogenation of an off-grade Ti sponge was used as the feedstock. The deoxidation of TiH2 was performed at 933 K for 12 h using Mg metal in magnesium chloride and potassium chloride molten salt under Ar and 10% H-2 mixed gas atmosphere. The influence of production scale on the concentration of oxygen (O) in the obtained residues was investigated by increasing the amount of TiH2 feedstock up to 2500 g/batch. After the deoxidation process, a mixture of Ti and TiH2 was obtained, and the O concentration in the mixture decreased from 11750 to 1480 ppm under certain conditions. The results demonstrate that the deoxidation of TiH2 using Mg metal under Ar and H-2 mixed gas can decrease the O concentration in an off-grade Ti sponge below 1800 ppm, even though the production scale increased under optimal conditions.

| ○ | ○ | Article | A comparative study on the optical and structural degradation behaviors and enhanced stability of CsPbBr3 embedded in oxide barriers | A series of experiments were conducted to investigate the optical and structural degradation behavior and enhanced stability of CsPbBr3 quantum dots (CPB QDs) embedded in oxide barrier materials such as SiOx, AlOx, and SiOx-AlOx by monitoring photoluminescence (PL) intensity, morphology, and phase under various envi-ronmental conditions such as UV exposure and ambient temperatures. Pristine CPB QDs showed a significant reduction in PL intensity under all environmental conditions even in the dark. The CPB QDs embedded in oxide materials showed relatively enhanced stabilities in general. The use of mixed-oxide SiOx-AlOx embedment for CPB QDs demonstrated better stability than the use of single-oxide embedment (SiOx and AlOx). The enhanced stability could be attributed to the reduced number of defects such as pinholes and voids by the synergistic effect of mixed oxides as barrier layers. These results offer an avenue and better understanding to improve the stability of CPB QDs for diverse applications. | Won, Hayeon; Kim, Jong-Hwa; Jung, Jinjoo; Kim, Do-Hyung | Kyungpook Natl Univ, Dept Phys, Nanoappl Phys Lab, Daegu 41566, South Korea; Korea Basic Sci Inst, Daegu Ctr, Daegu 41566, South Korea | 57169763200; 57208450662; 55750032400; 57007491900 | jjjung@knu.ac.kr;kimdh@knu.ac.kr; | SOLID STATE SCIENCES | SOLID STATE SCI | 1293-2558 | 1873-3085 | 136 | SCIE | CHEMISTRY, INORGANIC & NUCLEAR;CHEMISTRY, PHYSICAL;PHYSICS, CONDENSED MATTER | 2023 | 3.4 | 30.7 | 0.11 | 2025-06-25 | 1 | 1 | CsPbBr3 quantum dots; Passivation; Photoluminescence; Photostability; Thermal stability; Synergistic effect | PEROVSKITE QUANTUM DOTS; HIGHLY LUMINESCENT; NANOCRYSTALS; EFFICIENT; PHOTOLUMINESCENCE; NANOCOMPOSITES; ENCAPSULATION; TRANSPARENT; PERFORMANCE; EMISSION | CsPbBr3 quantum dots; Passivation; Photoluminescence; Photostability; Synergistic effect; Thermal stability | Bromine compounds; Lead compounds; Nanocrystals; Photoluminescence; Semiconductor quantum dots; Silicon; Silicon compounds; Stability; Cspbbr3 quantum dot; Degradation behavior; Enhanced stability; Environmental conditions; Optical degradation; Photo-stability; Photoluminescence intensities; SiO x; Structural degradation; Synergistic effect; Passivation | English | 2023 | 2023-02 | 10.1016/j.solidstatesciences.2022.107087 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Anatomical View of Thoracodorsal Artery Variants Using Computed Tomography Angiography | Background The latissimus dorsi (LD) muscle has a dominant pedicle with one thoracodorsal artery and receives sufficient blood by segmental circulation through several perforators. Thus, it is widely used in various reconstructive surgeries. We are reporting on the patterns of the thoracodorsal artery analyzed by chest computed tomography (CT) angiography.Methods We analyzed the preoperative chest CT angiography results of 350 patients scheduled to undergo LD flap breast reconstruction following complete mastectomy for breast cancer between October 2011 and October 2020.Results A total of 700 blood vessels were classified according to the Kyungpook National University Plastic Surgery-Thoracodorsal Artery (KNUPS-TDA) classification: 388 (185 right and 203 left), 126 (64 right and 62 left), 91 (49 right and 42 left), 57 (27 right and 30 left), and 38 (25 right and 13 left) vessels were classified as type I, type II, type III, type IV, and type V, respectively. Among 350 patients, 205 patients showed matching types for left and right vessels, whereas 145 patients showed mismatching types. For 205 patients with matching types, the distribution by type was 134, 30, 30, 7, and 4 patients with type I, type II, type III, type IV, and type V, respectively. For 145 patients with mismatching types, the distribution by different combinations was 48, 25, 28, 19, 2, 9, 7, 3, 1, and 3 patients with type I + type II, type I + type III, type I + type IV, type I + type V, type II + type III, type II + type IV, type II + type V, type III + type IV, type III + type V, and type IV + type V, respectively.Conclusion While there is some diversity in the vascular anatomical structures of the LD flap, the dominant vessel can be found in a similar location in almost all cases and no flap had absence of a dominant vessel. Therefore, in surgical procedures using the thoracodorsal artery as the pedicle, preoperative radiological confirmation is not absolutely necessary; however, due to variants, performing the surgery with an understanding of this aspect should lead to good outcomes. | Cho, Hyun Geun; Kang, Byeongju; Ryu, Jeong Yeop; Choi, Kang Young; Yang, Jung Dug; Chung, Ho Yun; Cho, Byung Chae; Lee, Jeeyeon; Park, Ho Yong; Lee, Joon Seok | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Plast & Reconstruct Surg, 807 Hoguk Ro, Daegu 41404, South Korea | Lee, Jong-Mok/KVY-9550-2024; Ryu, Jeong Yeop/GLQ-9419-2022; Yang, Jung/R-7806-2019; LEE, JIN/Q-3108-2018; PARK, JUN-YOUNG/P-5981-2015 | leejspo@knu.ac.kr; | JOURNAL OF RECONSTRUCTIVE MICROSURGERY | J RECONSTR MICROSURG | 0743-684X | 1098-8947 | 39 | 08 | SCIE | SURGERY | 2023 | 2.2 | 30.7 | 2 | latissimus dorsi flap; thoracodorsal artery; pedicle; vascular anatomy | LATISSIMUS-DORSI FLAP; BREAST RECONSTRUCTION; MUSCULOCUTANEOUS FLAP; BRANCH | English | 2023 | 2023-10 | 10.1055/a-2040-1651 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Comparative study of supracervical hysterectomy between da Vinci SP® surgical system and conventional single-site laparoscopy for uterine fibroid: single center experiences | This study aimed to review the surgical outcomes of supracervical hysterectomy using the da Vinci SP (R) surgical system and conventional single-site laparoscopic surgery for uterine fibroids. This study included 79 patients who underwent supracervical hysterectomy with the da Vinci SP (R) surgical system and conventional single-site laparoscopy for uterine fibroid between June 2018 and April 2021. All the surgeries were performed by an experienced surgeon. Surgical outcomes and complications were reviewed in both groups. No significant difference was found between the two groups with regards to the patients' preoperative surgical conditions such as weight of the uterus, history of pelvic surgery, and pelvic adhesion. A significantly longer operation time (p < 0.01) and higher levels of C-reactive protein (p < 0.01) were found in the robotic surgery group; in particular, the uterus-out time was significantly longer (p < 0.01). No significant differences were found in other surgical outcomes such as complication rates and hospital stays. Supracervical hysterectomy using the da Vinci (R) SP surgical system is comparable to conventional single-site laparoscopy in uncomplicated cases. However, it requires a significantly longer operative time and has a higher inflammatory response. | Lee, Juhun; Hong, Dae Gy | Kyungpook Natl Univ, Sch Med, Dept Obstet & Gynecol, Daegu, South Korea | 57360628800; 26656670100 | dghong@knu.ac.kr; | JOURNAL OF ROBOTIC SURGERY | J ROBOT SURG | 1863-2483 | 1863-2491 | 17 | 4 | SCIE | SURGERY | 2023 | 2.2 | 30.7 | 0.45 | 2025-06-25 | 3 | 3 | Robotic hysterectomy; Minimally invasive surgery; Supracervical hysterectomy; Single-site laparoscopic hysterectomy; da Vinci SP surgery system | da Vinci SP surgery system; Minimally invasive surgery; Robotic hysterectomy; Single-site laparoscopic hysterectomy; Supracervical hysterectomy | Female; Humans; Hysterectomy; Laparoscopy; Leiomyoma; Retrospective Studies; Robotic Surgical Procedures; Uterus; Robotic surgery; Surgical equipment; Transplantation (surgical); C reactive protein; hemoglobin; Da vinci SP surgery system; Minimally-invasive surgery; Robotic hysterectomy; Single sites; Single-site laparoscopic hysterectomy; Supracervical hysterectomy; Surgery systems; Surgical outcome; Surgical systems; Uterine fibroids; adhesiolysis; adult; Article; bleeding; body mass; comparative study; controlled study; endometriosis; female; human; intestine injury; laparoscopy; major clinical study; middle aged; myomectomy; ovarian cystectomy; pelvic adhesion; perforation; postoperative hemorrhage; salpingooophorectomy; skin incision; subtotal hysterectomy; ureter injury; uterus myoma; vaginal perforation; hysterectomy; leiomyoma; procedures; retrospective study; robot assisted surgery; uterus; Laparoscopy | English | 2023 | 2023-08 | 10.1007/s11701-023-01527-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Functional expression of RuBisCO reduces CO2 emission during fermentation by engineered Saccharomyces cerevisiae | Industrial biotechnology based on yeast fermentation is a promising strategy that can alleviate global warming and climate change. However, Saccharomyces cerevisiae, widely used in bioprocesses, releases a large amount of carbon dioxide (CO2) during fermentation. This study developed a mixotrophic CO2-fixing S. cerevisiae to achieve carbon neutrality and sustainability in bioprocess. A CO2-fixation pathway was constructed in a xylose-utilizing S. cerevisiae by heterologous expression of ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO) and phosphoribulokinase (PRK). Furthermore, a delta-integration strategy was utilized, and the RuBisCO gene copy number was increased to 10 copies to improve the efficiency of CO2-fixation. An additional Cas9-based genome editing was performed to overexpress other CO2-fixation related genes. The resulting CO2-fixing yeast, SJ03, exhibited the highest RuBisCO activity. During anaerobic xylose fermentation, ethanol concentration was increased by 17% and ethanol yield was increased by 16% compared to the control strain. In addition, CO2 emissions decreased by 7%. These results suggest that overexpression of the CO2-fixation pathway coupled with xylose utilization in S. cerevisiae might reduce CO2 emission in bioprocesses. | Park, Sujeong; Park, Bo-Ram; Jeong, Deokyeol; Park, Jongbeom; Ko, Ja Kyong; Kim, Soo-Jung; Kim, Jeong-Sun; Jin, Yong-Su; Kim, Soo Rin | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Rural Dev Adm, Dept Agrofood Resources, Natl Inst Agr Sci, Wanju Gun 55365, South Korea; Purdue Univ, Dept Food Sci, W Lafayette, IN 47907 USA; Korea Inst Sci & Technol KIST, Clean Energy Res Ctr, Seoul 02792, South Korea; Chonnam Natl Univ, Dept Integrat Food Biosci & Biotechnol, Gwangju 61186, South Korea; Chonnam Natl Univ, Dept Chem, Gwangju 61186, South Korea; Univ Illinois, Dept Food Sci & Human Nutr, Urbana, IL 61801 USA; Kyungpook Natl Univ, Res Inst Tailored Food Technol, Daegu 41566, South Korea | ; Kim, Sun/C-2026-2011; Kim, Soo Rin/X-2192-2019; Jeong, Deokyeol/GLR-8021-2022; Jin, Yong-Su/L-4530-2013 | 57218916250; 56263412100; 57191332457; 57223133187; 56603594800; 57092299400; 7601379316; 57204009076; 36659584200 | soorinkim@knu.ac.kr; | PROCESS BIOCHEMISTRY | PROCESS BIOCHEM | 1359-5113 | 1873-3298 | 134 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENGINEERING, CHEMICAL | 2023 | 3.7 | 30.7 | 1.55 | 2025-06-25 | 8 | 10 | Carbon dioxide fixation; Ribulose-1; 5-bisphosphate carboxylase/oxygenase; Saccharomyces cerevisiae; Delta-integration strategy; CRISPR/Cas9 | 5-bisphosphate carboxylase/oxygenase; Carbon dioxide fixation; CRISPR/Cas9; Delta-integration strategy; Ribulose-1; Saccharomyces cerevisiae | Ethanol; Fermentation; Genes; Global warming; Yeast; 5-bisphosphate; 5-bisphosphate carboxylase/oxygenase; Carbon dioxide fixation; CO 2 emission; CRISPR/cas9; Delta-integration strategy; Integration strategy; Oxygenases; Ribulose; Ribulose-1; Carbon dioxide | English | 2023 | 2023-11 | 10.1016/j.procbio.2023.10.013 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Visible and mid-infrared spectral features of Dy³⁺: SrF2 and Dy³⁺/Y³⁺: SrF2 crystals | In this work, Dy3+: SrF2 and Dy3+/Y3+: SrF2 crystals have been grown successfully by the Bridgman-Stockbarger method, and their absorption spectra, visible and mid-infrared (MIR) emission spectra, as well as fluorescence decay curves were analyzed. The advantages of co-doping Y3+ ions on the yellow and MIR emissions of Dy3+ ions were investigated. The intensity of yellow emission in the doubly-doped crystal is - 4 times stronger than that of the singly-doped crystal. The absorption cross-section (0.782 x 10(-21) cm(2)) at 452 nm and emission cross-section (1.156 x 10(-21)cm(2)) at 573 nm of Dy3+/Y3+: SrF(2 )crystal is higher than that of Dy3+: SrF2 crystal related values. Also, compared to Dy3+: SrF2 crystal, the emission cross-section (3.55 x 10(-21) cm(2)) at 2880 nm and fluorescence decay time (1.062 ms) of Dy3+/Y3+: SrF2 crystal are found to be higher. When co-doped Y3+ ions, the distance between Dy3+ ions increased leading to the reduction of cross-relaxation and resonant energy transfer probabilities while enhancing the intensities of yellow and MIR emissions.

This has resulted in the rise of grid interfaced renewable energy sources (RES), rapid deployment of battery energy storage systems (BESS) coupled with energy managment systems (EMS), and DC based grid. This paper presents a center-tapped transformer-based single-stage single-phase full-bridge (FB) bidirectional AC-DC converter and its control strategy to improve controllability and reliability in applications such as DC distribution, PV/BESS grid interfacing, vehicle to grid (V2G), and so on. In contrast to conventional galvanically isolated topologies, a single-phase center-tapped transformer is introduced. It links and galvanically isolates the converters and the grid and provides its leakage inductance as the needed inductor required for current control (depending on the design). Furthermore, it reduces the number of conventionally required power conversion stages by employing a wide DC-bus voltage control strategy, resulting in a single converter that undergoes a single power conversion. Additionally, the voltage level can be increased to further enhance the output quality by cascading multiple converters (Multi-Level). The structure, operation, and basic control scheme are discussed in detail. Verification through a 220 V-rms, 1.8 kVA, and 45 similar to 100 V(DC )simulation and small-scale experimental prototype (60 similar to 100 V-DC voltage) for practical validation of the topology is also presented. | Obi, Arinze Stephen; Lee, Si-Heon; Jung, Hyun-Sam; Jung, Jae-Jung | Kyungpook Natl Univ, Dept Elect & Elect Engn, Daegu 41566, South Korea; Dongguk Univ, Dept Elect & Elect Engn, Seoul 04620, South Korea | Jung, Hyun-Sam/AAG-4817-2019 | 58119304800; 58119189400; 50061604600; 55368433400 | jj.jung@knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 4 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 0.26 | 2025-06-25 | 1 | 2 | AC-DC converter; center-tapped transformer; inverter; single-phase converter; wide DC-bus control; battery energy storage system | BATTERY ENERGY-STORAGE; INTEGRATION; INVERTERS | AC-DC converter; battery energy storage system; center-tapped transformer; inverter; single-phase converter; wide DC-bus control | Battery storage; DC transformers; Electric inverters; Electric loads; Power quality; Rectifying circuits; Renewable energy resources; Secondary batteries; Vehicle-to-grid; A-center; AC-DC converter; Battery energy storage systems; Center tapped transformers; DC converter; Inverte; Power load; Single phase converter; Single phasis; Wide DC-bus control; article; control strategy; reliability; simulation; Topology | English | 2023 | 2023-02 | 10.3390/s23042227 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A Miniaturized Tri-Band Implantable Antenna for ISM/WMTS/Lower UWB/Wi-Fi Frequencies | This study aims to design a compact antenna structure suitable for implantable devices, with a broad frequency range covering various bands such as the Industrial Scientific and Medical band (868-868.6 MHz, 902-928 MHz, 5.725-5.875 GHz), the Wireless Medical Telemetry Service (WMTS) band, a subset of the unlicensed 3.5-4.5 GHz ultra-wideband (UWB) that is free of interference, and various Wi-Fi spectra (3.6 GHz, 4.9 GHz, 5 GHz, 5.9 GHz, 6 GHz). The antenna supports both low and high frequencies for efficient data transfer and is compatible with various communication technologies. The antenna features an asynchronous-meandered radiator, a parasitic patch, and an open-ended square ring-shaped ground plane. The antenna is deployed deep inside the muscle layer of a rectangular phantom below the skin and fat layer at a depth of 7 mm for numerical simulation. Furthermore, the antenna is deployed in a cylindrical phantom and bent to check the suitability for different organs. A prototype of the antenna is created, and its reflection coefficient and radiation patterns are measured in fresh pork tissue. The proposed antenna is considered a suitable candidate for implantable technology compared to other designs reported in the literature. It can be observed that the proposed antenna in this study has the smallest volume (75 mm(3)) and widest bandwidth (181.8% for 0.86 GHz, 9.58% for 1.43 GHz, and 285.7% for the UWB subset and Wi-Fi). It also has the highest gain (-26 dBi for ISM, -14 dBi for WMTS, and -14.2 dBi for UWB subset and Wi-Fi) compared to other antennas in the literature. In addition, the SAR values for the proposed antenna are well below the safety limits prescribed by IEEE Std C95.1-1999, with SAR values of 0.409 W/Kg for 0.8 GHz, 0.534 W/Kg for 1.43 GHz, 0.529 W/Kg for 3.5 GHz, and 0.665 W/Kg for 5.5 GHz when the applied input power is 10 mW. Overall, the proposed antenna in this study demonstrates superior performance compared to existing tri-band implantable antennas in terms of size, bandwidth, gain, and SAR values. | Gupta, Anupma; Kumar, Vipan; Bansal, Shonak; Alsharif, Mohammed H.; Jahid, Abu; Cho, Ho-Shin | Chitkara Univ, Chitkara Univ Inst Engn & Technol, Dept Interdisciplinary Courses Engn, Rajpura 140401, India; Sri Sai Coll Engn & Technol, Dept ECE, Badhani 145001, Pathankot, India; Chandigarh Univ, Dept ECE, Mohali 140413, India; Sejong Univ, Coll Elect & Informat Engn, Dept Elect Engn, 209 Neungdong Ro, Seoul 05006, South Korea; Univ Ottawa, Sch Elect Engn & Comp Sci, 25 Templeton St, Ottawa, ON K1N 6N5, Canada; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | ; kumar, vipan/I-8328-2014; Bansal, Dr. Shonak/O-7677-2014; Jahid, Abu/L-8365-2017; Gupta, Anupma/AAR-1043-2021; Alsharif, Mohammed H./X-7516-2018 | 57209589407; 57201736791; 57225812790; 55968967000; 36988077400; 35316924900 | malsharif@sejong.ac.kr;ajahi011@uottawa.ca;hscho@ee.knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 15 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 3.4 | 2025-06-25 | 16 | 27 | tri-band; implantable antenna; ISM; WMTS bands; parasitic patch; asynchronous-spiral radiator; communication technologies; smart antennas | BANDWIDTH ENHANCEMENT; SYSTEM | asynchronous–spiral radiator; communication technologies; implantable antenna; ISM/WMTS bands; parasitic patch; smart antennas; tri-band | Antenna grounds; Data transfer; Directional patterns (antenna); IEEE Standards; Microstrip antennas; Microwave antennas; Phantoms; Radiators; Ultra-wideband (UWB); Wearable antennas; Wi-Fi; Wireless local area networks (WLAN); Antenna structures; Asynchronoi–spiral radiator; Communicationtechnology; Compact antenna; Implantable antennas; ISM/wireless medical telemetry service band; Medical telemetry; Parasitic patch; Tri-bands; Ultrawide band; Slot antennas | English | 2023 | 2023-08 | 10.3390/s23156989 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A Study on the Effectiveness of Deep Learning-Based Anomaly Detection Methods for Breast Ultrasonography | In the medical field, it is delicate to anticipate good performance in using deep learning due to the lack of large-scale training data and class imbalance. In particular, ultrasound, which is a key breast cancer diagnosis method, is delicate to diagnose accurately as the quality and interpretation of images can vary depending on the operator's experience and proficiency. Therefore, computer-aided diagnosis technology can facilitate diagnosis by visualizing abnormal information such as tumors and masses in ultrasound images. In this study, we implemented deep learning-based anomaly detection methods for breast ultrasound images and validated their effectiveness in detecting abnormal regions. Herein, we specifically compared the sliced-Wasserstein autoencoder with two representative unsupervised learning models autoencoder and variational autoencoder. The anomalous region detection performance is estimated with the normal region labels. Our experimental results showed that the sliced-Wasserstein autoencoder model outperformed the anomaly detection performance of others. However, anomaly detection using the reconstruction-based approach may not be effective because of the occurrence of numerous false-positive values. In the following studies, reducing these false positives becomes an important challenge. | Yun, Changhee; Eom, Bomi; Park, Sungjun; Kim, Chanho; Kim, Dohwan; Jabeen, Farah; Kim, Won Hwa; Kim, Hye Jung; Kim, Jaeil | Natl Informat Soc Agcy, Daegu 41068, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Chilgok Hosp, Dept Radiol, Daegu 41404, South Korea | 58136228600; 58136674400; 58136674500; 57216946967; 59109513700; 58135804100; 36081886500; 57203506201; 57211615348 | jaeilkim@knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 5 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 0.39 | 2025-06-25 | 4 | 3 | breast cancer; ultrasonography; deep learning; anomaly detection; autoencoder | anomaly detection; autoencoder; breast cancer; deep learning; ultrasonography | Deep Learning; Diagnosis, Computer-Assisted; Female; Humans; Image Processing, Computer-Assisted; Ultrasonography; Ultrasonography, Mammary; Computer aided diagnosis; Computer aided instruction; Deep learning; Diseases; Learning systems; Medical imaging; Ultrasonography; Anomaly detection; Anomaly detection methods; Auto encoders; Breast Cancer; Deep learning; Detection performance; False positive; Large-scales; Medical fields; Performance; computer assisted diagnosis; echography; echomammography; female; human; image processing; procedures; Anomaly detection | English | 2023 | 2023-03 | 10.3390/s23052864 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Aberration Estimation for Synthetic Aperture Digital Holographic Microscope Using Deep Neural Network | Digital holographic microscopy (DHM) is a valuable technique for investigating the optical properties of samples through the measurement of intensity and phase of diffracted beams. However, DHMs are constrained by Lagrange invariance, compromising the spatial bandwidth product (SBP) which relates resolution and field of view. Synthetic aperture DHM (SA-DHM) was introduced to overcome this limitation, but it faces significant challenges such as aberrations in synthesizing the optical information corresponding to the steering angle of incident wave. This paper proposes a novel approach utilizing deep neural networks (DNNs) for compensating aberrations in SA-DHM, extending the compensation scope beyond the numerical aperture (NA) of the objective lens. The method involves training a DNN from diffraction patterns and Zernike coefficients through a circular aperture, enabling effective aberration compensation in the illumination beam. This method makes it possible to estimate aberration coefficients from the only part of the diffracted beam cutoff by the circular aperture mask. With the proposed technique, the simulation results present improved resolution and quality of sample images. The integration of deep neural networks with SA-DHM holds promise for advancing microscopy capabilities and overcoming existing limitations. | Jeon, Hosung; Jung, Minwoo; Lee, Gunhee; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 56663784700; 57216159562; 57687190900; 10142501600 | jhs0485@knu.ac.kr;apvmf12@knu.ac.kr;gunhee7765@knu.ac.kr;jhahn@knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 22 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 0 | 2025-06-25 | 0 | 0 | synthetic aperture; holographic microscope; deep neural network; aberration estimation | WIDE-FIELD; HIGH-RESOLUTION; COMPENSATION; ILLUMINATION | aberration estimation; deep neural network; holographic microscope; synthetic aperture | Aberrations; Holography; Image enhancement; Microscopic examination; Phase measurement; Synthetic apertures; Aberration estimation; Bandwidth product; Circular aperture; Diffracted beams; Digital holographic microscopy; Field of views; Holographic microscope; Lagrange; Measurements of; Spatial bandwidth; article; bandwidth; controlled study; deep neural network; diagnosis; diffraction; human; illumination; lens (optics); microscope; microscopy; simulation; Deep neural networks | English | 2023 | 2023-11 | 10.3390/s23229278 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Agricultural Robot-Centered Recognition of Early-Developmental Pest Stage Based on Deep Learning: A Case Study on Fall Armyworm (Spodoptera frugiperda) | Accurately detecting early developmental stages of insect pests (larvae) from off-the-shelf stereo camera sensor data using deep learning holds several benefits for farmers, from simple robot configuration to early neutralization of this less agile but more disastrous stage. Machine vision technology has advanced from bulk spraying to precise dosage to directly rubbing on the infected crops. However, these solutions primarily focus on adult pests and post-infestation stages. This study suggested using a front-pointing red-green-blue (RGB) stereo camera mounted on a robot to identify pest larvae using deep learning. The camera feeds data into our deep-learning algorithms experimented on eight ImageNet pre-trained models. The combination of the insect classifier and the detector replicates the peripheral and foveal line-of-sight vision on our custom pest larvae dataset, respectively. This enables a trade-off between the robot's smooth operation and localization precision in the pest captured, as it first appeared in the farsighted section. Consequently, the nearsighted part utilizes our faster region-based convolutional neural network-based pest detector to localize precisely. Simulating the employed robot dynamics using CoppeliaSim and MATLAB/SIMULINK with the deep-learning toolbox demonstrated the excellent feasibility of the proposed system. Our deep-learning classifier and detector exhibited 99% and 0.84 accuracy and a mean average precision, respectively. | Obasekore, Hammed; Fanni, Mohamed; Ahmed, Sabah Mohamed; Parque, Victor; Kang, Bo-Yeong | Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu 41566, South Korea; Mansoura Univ, Prod Engn & Mech Design Dept, Mansoura 35516, Egypt; Egypt Japan Univ Sci & Technol, Dept Mechatron & Robot Engn, Alexandria 21934, Egypt; Assiut Univ, Elect Engn Dept, Assiut 71515, Egypt; Waseda Univ, Dept Modern Mech Engn, Tokyo 1698050, Japan | Obasekore, Hammed/HTL-7429-2023; Parque, Victor/K-7732-2018; Kang, Bo-Yeong/IXW-6764-2023 | 57211521199; 6508205542; 55456828900; 35305647500; 26643468300 | kby09@knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 6 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 1.57 | 2025-06-25 | 9 | 12 | agricultural robotics; classification; deep-learning; detection; fall armyworm | agricultural robotics; classification; deep-learning; detection; fall armyworm | Agriculture; Animals; Deep Learning; Insecta; Larva; Neural Networks, Computer; Robotics; Spodoptera; Agricultural robots; Agriculture; Cameras; Convolutional neural networks; Deep learning; Economic and social effects; Fall detection; Learning algorithms; Stereo image processing; Agricultural robot; Agricultural robotics; Case-studies; Deep-learning; Detection; Developmental stage; Fall armyworm; Insects pests; Spodoptera frugiperda; Stereo cameras; agriculture; animal; insect; larva; robotics; Spodoptera; Classification (of information) | English | 2023 | 2023-03 | 10.3390/s23063147 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | ARiRTN: A Novel Learning-Based Estimation Model for Regressing Illumination | In computational color constancy, regressing illumination is one of the most common approaches to manifesting the original color appearance of an object in a real-life scene. However, this approach struggles with the challenge of accuracy arising from label vagueness, which is caused by unknown light sources, different reflection characteristics of scene objects, and extrinsic factors such as various types of imaging sensors. This article introduces a novel learning-based estimation model, an aggregate residual-in-residual transformation network (ARiRTN) architecture, by combining the inception model with the residual network and embedding residual networks into a residual network. The proposed model has two parts: the feature-map group and the ARiRTN operator. In the ARiRTN operator, all splits perform transformations simultaneously, and the resulting outputs are concatenated into their respective cardinal groups. Moreover, the proposed architecture is designed to develop multiple homogeneous branches for high cardinality, and an increased size of a set of transformations, which extends the network in width and in length. As a result of experimenting with the four most popular datasets in the field, the proposed architecture makes a compelling case that complexity increases accuracy. In other words, the combination of the two complicated networks, residual and inception networks, helps reduce overfitting, gradient distortion, and vanishing problems, and thereby contributes to improving accuracy. Our experimental results demonstrate this model's outperformance over its most advanced counterparts in terms of accuracy, as well as the robustness of illuminant invariance and camera invariance. | Choi, Ho-Hyoung; Kim, Gi-Seok | Kyungpook Natl Univ, Adv Dent Device Dev Inst, Sch Dent, Daegu 41940, South Korea; Gyeongju Univ, Sch Logos Coll, Gyeongjusi 38065, South Korea | 37048369000; 58671855400 | chhman2000@msn.com;kimgs@gu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 20 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 0.39 | 2025-06-25 | 3 | 3 | computational color constancy; learning-based estimation model; primary color; appearance; unknown light source; ARiRTN architecture | COLOR CONSTANCY | appearance; ARiRTN architecture; computational color constancy; learning-based estimation model; primary color; unknown light source | English | 2023 | 2023-10 | 10.3390/s23208558 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Blockchain-Based Data Access Control and Key Agreement System in IoT Environment | Recently, with the increasing application of the Internet of Things (IoT), various IoT environments such as smart factories, smart homes, and smart grids are being generated. In the IoT environment, a lot of data are generated in real time, and the generated IoT data can be used as source data for various services such as artificial intelligence, remote medical care, and finance, and can also be used for purposes such as electricity bill generation. Therefore, data access control is required to grant access rights to various data users in the IoT environment who need such IoT data. In addition, IoT data contain sensitive information such as personal information, so privacy protection is also essential. Ciphertext-policy attribute-based encryption (CP-ABE) technology has been utilized to address these requirements. Furthermore, system structures applying blockchains with CP-ABE are being studied to prevent bottlenecks and single failures of cloud servers, as well as to support data auditing. However, these systems do not stipulate authentication and key agreement to ensure the security of the data transmission process and data outsourcing. Accordingly, we propose a data access control and key agreement scheme using CP-ABE to ensure data security in a blockchain-based system. In addition, we propose a system that can provide data nonrepudiation, data accountability, and data verification functions by utilizing blockchains. Both formal and informal security verifications are performed to demonstrate the security of the proposed system. We also compare the security, functional aspects, and computational and communication costs of previous systems. Furthermore, we perform cryptographic calculations to analyze the system in practical terms. As a result, our proposed protocol is safer against attacks such as guessing attacks and tracing attacks than other protocols, and can provide mutual authentication and key agreement functions. In addition, the proposed protocol is more efficient than other protocols, so it can be applied to practical IoT environments. | Lee, JoonYoung; Kim, MyeongHyun; Park, KiSung; Noh, SungKee; Bisht, Abhishek; Das, Ashok Kumar; Park, Youngho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Decentralized Network Res Sect, Daejeon 34129, South Korea; Int Inst Informat Technol, Ctr Secur, Theory & Algorithm Res, Hyderabad 500032, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Park, Kisung/KIG-3849-2024; Lee, JoonYoung/AAM-9838-2021; Das, Ashok Kumar/U-2790-2019 | 57203970123; 57210278739; 57194833768; 56207592700; 58078371600; 55450732800; 56962990300 | harry250@knu.ac.kr;kimmyeong123@knu.ac.kr;ks.park@etri.re.kr;sknoh@etri.re.kr;abhishek.bisht@research.iiit.ac.in;ashok.das@iiit.ac.in;parkyh@knu.ac.kr; | SENSORS | SENSORS-BASEL | 1424-8220 | 23 | 11 | SCIE | CHEMISTRY, ANALYTICAL;ENGINEERING, ELECTRICAL & ELECTRONIC;INSTRUMENTS & INSTRUMENTATION | 2023 | 3.4 | 30.9 | 1.18 | 2025-06-25 | 8 | 9 | IoT data; CP-ABE; data validation; data nonrepudiation; data accountability; security; authentication | SCHEME; SECURITY | authentication; CP-ABE; data nonrepudiation, data accountability; data validation; IoT data; security | Artificial Intelligence; Blockchain; Communication; Computer Security; Electricity; Internet; Automation; Blockchain; Cryptography; Intelligent buildings; Internet of things; Sensitive data; Authentication and key agreements; Block-chain; Ciphertext-policy attribute-based encryptions; Data access control; Data accountabilities; Data nonrepudiation, data accountability; Data validation; Internet of thing data; Non repudiation; Security; article; artificial intelligence; blockchain; calculation; electricity; encryption; factory; finance; identifiable information; information security; internet of things; medical care; privacy; Authentication | English | 2023 | 2023-05-29 | 10.3390/s23115173 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
