| ○ | ○ | Article | Understanding the Grain Boundary Behavior of Bimetallic Platinum-Cobalt Alloy Nanowires toward Oxygen Electro-Reduction | Grain boundaries (GBs) are defects in crystal structures, which are in general known to be highly active toward various electrocatalytic reactions. Herein, we identify the adverse behaviors of the GBs for bimetallic platinum-cobalt (Pt-Co) nanocatalysts in the oxygen reduction reaction (ORR). As model catalysts, GB-rich Pt-Co nanowires (Pt-Co GB-NWs) and single-crystalline Pt-Co nanowires (Pt-Co SC-NWs) are synthesized. They have very similar diameters, Pt-to-Co ratios, and Pt-rich surface structures, except for the GB populations, which can be precisely controlled by applying an external magnetic field during their synthesis. The presence of GBs in Pt-Co NWs promotes Co leaching at an applied electrochemical potential, inducing significant changes in the surface Pt-to-Co ratio. The resulting Pt-Co GB-NWs perform only half the ORR activity compared with the Pt-Co SC-NWs. As a result, it is revealed that the surface GB sites are deactivated by causing elemental leaching and may not act as an ORR promoter for the Pt-Co nanowire catalyst. | Kabiraz, Mrinal Kanti; Ruqia, Bibi; Kim, Jeonghyeon; Kim, Haesol; Kim, Hee Jin; Hong, Youngmin; Kim, Mi Ji; Kim, Young Kyoung; Kim, Chan; Lee, Won-Jae; Lee, Wonkyun; Hwang, Gyo Hyun; Ri, Hyeong Cheol; Baik, Hionsuck; Oh, Hyung-Suk; Lee, Young Wook; Gao, Lei; Huang, Hongwen; Paek, Seung Min; Jo, Youn-Jung; Choi, Chang Hyuck; Han, Sang Woo; Choi, Sang-Il | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Gwangju Inst Sci & Technol, Sch Mat Sci & Engn, Gwangju 61005, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Heterogeneous Catalysis PJT, LG Chem Res Pk, Daejeon 34122, South Korea; Korea Basic Sci Inst KBSI, Seoul 02841, South Korea; Korea Inst Sci & Technol KIST, Clean Energy Res Ctr, Seoul 02792, South Korea; Gyeongsang Natl Univ, Res Inst Nat Sci, Dept Chem Educ, Jinju 52828, South Korea; Hunan Univ, Minist Educ, Adv Catalyt Engn Res Ctr, Coll Mat Sci & Engn, Changsha 410082, Hunan, Peoples R China; Pohang Univ Sci & Technol POSTECH, Dept Chem, Pohang 37673, South Korea; Korea Adv Inst Sci & Technol, Dept Chem, Ctr Nanotecton, Daejeon 34141, South Korea; Korea Adv Inst Sci & Technol, KI Nano Century, Daejeon 34141, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | Han, Sang/C-1789-2011; Choi, Chang Hyuck/M-8129-2018; Oh, Hyung-Suk/AID-0267-2022; Choi, Sang-Il/AGR-1133-2022; Paek, Seung-Min/E-4667-2011; Ruqia, Bibi/AAR-4698-2020; Han, Sang Woo/C-1789-2011; Kabiraz, Mrinal/AAE-6381-2020; Huang, Hongwen/AAD-6853-2020; Gao, Lei/KFQ-7375-2024 | 57201400780; 56850407000; 57194560892; 57203249866; 57193334513; 57194557373; 57284199000; 57219092979; 54684058600; 57203094506; 57217279536; 57208330842; 56277557600; 7101961237; 57755728400; 55716174300; 57190169111; 55738280200; 7102686289; 13502586500; 58305582800; 26643463400; 56167600800 | chchoi@postech.ac.kr;sangwoohan@kaist.ac.kr;sichoi@knu.ac.kr; | ACS CATALYSIS | ACS CATAL | 2155-5435 | 12 | 6 | SCIE | CHEMISTRY, PHYSICAL | 2022 | 12.9 | 13.4 | 2.49 | 2025-06-25 | 47 | 46 | platinum; cobalt; nanowire; grain boundary; oxygen reduction reaction | ELECTROCATALYSTS; CATALYSTS; EVOLUTION; GROWTH | cobalt; grain boundary; nanowire; oxygen reduction reaction; platinum | Binary alloys; Cobalt alloys; Electrocatalysis; Electrolytic reduction; Leaching; Nanocatalysts; Nanowires; Oxygen; Platinum alloys; Alloy nanowires; Bimetallics; Boundary behaviour; Cobalt nanowires; Defect in crystals; Grain-boundaries; Oxygen electro reductions; Oxygen reduction reaction; Platinum-cobalt alloys; Platinum/cobalt; Grain boundaries | English | 2022 | 2022-03-18 | 10.1021/acscatal.1c05766 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Characterizing the effects of different chemicals on stem bending of cut snapdragon flower | Background This study investigated the effects of ethylene release compounds (ethephon), ethylene-action inhibitors (silver thiosulfate: STS), and nitric oxide donor (sodium nitroprusside: SNP) on stem bending of snapdragon flowers. Moreover, the effects of plant growth supplements [6-benzyladenine (BA), gibberellic acid 3 (GA(3)), and calcium chloride (CaCl2)] on the stem bending were also extensively investigated. Results Ethephon completely prevented stem bending until 9 days after treatment (9 DAT). STS exhibited the highest bending rate, while SNP did not significantly affect the bending compared to the controls. The bending results were associated with the results of stem curvature, relative shoot elongation, ethylene production, and lignin content, that are involved in the stem bending mechanism. This was proven by the expression analysis of genes involved in ethylene and lignin biosynthetic pathways. The addition of plant growth supplements slightly or significantly delayed stem bending in the treatments (control, SNP, and STS) and significantly reduced petal senescence in ethephon at 9 DAT. Conclusion These results show the preventive role of ethephon in the stem bending of cut snapdragon. Moreover, the combination of ethephon with supplements also provided information that could guide the development of strategies to delay stem bending in other cut flowers that undergo serious bending during a short vase life. | Soe, May Thu; Naing, Aung Htay; Kim, Soo Rin; Kim, Chang Kil | Kyungpook Natl Univ, Dept Hort, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | Kim, Soo Rin/X-2192-2019; Naing, Aung Htay/AAF-4277-2019 | 57217678838; 37112768100; 36659584200; 7409880701 | ckkim@knu.ac.kr; | PLANT METHODS | PLANT METHODS | 1746-4811 | 18 | 1 | SCIE | BIOCHEMICAL RESEARCH METHODS;PLANT SCIENCES | 2022 | 5.1 | 13.6 | 0.65 | 2025-06-25 | 6 | 7 | Ethylene production; Gene expression; Growth supplements; Lignin content; Petal senescence | ETHYLENE BIOSYNTHESIS; VASE LIFE; ETHEPHON; CALCIUM; LIGNIFICATION; LIGNIN | Ethylene production; Gene expression; Growth supplements; Lignin content; Petal senescence | English | 2022 | 2022-01-13 | 10.1186/s13007-021-00835-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Machine learning models to predict the maximum severity of COVID-19 based on initial hospitalization record | Background: As the worldwide spread of coronavirus disease 2019 (COVID-19) continues for a long time, early prediction of the maximum severity is required for effective treatment of each patient. Objective: This study aimed to develop predictive models for the maximum severity of hospitalized COVID-19 patients using artificial intelligence (AI)/machine learning (ML) algorithms. Methods: The medical records of 2,263 COVID-19 patients admitted to 10 hospitals in Daegu, Korea, from February 18, 2020, to May 19, 2020, were comprehensively reviewed. The maximum severity during hospitalization was divided into four groups according to the severity level: mild, moderate, severe, and critical. The patient's initial hospitalization records were used as predictors. The total dataset was randomly split into a training set and a testing set in a 2:1 ratio, taking into account the four maximum severity groups. Predictive models were developed using the training set and were evaluated using the testing set. Two approaches were performed: using four groups based on original severity levels groups (i.e., 4-group classification) and using two groups after regrouping the four severity level into two (i.e., binary classification). Three variable selection methods including randomForestSRC were performed. As AI/ML algorithms for 4-group classification, GUIDE and proportional odds model were used. For binary classification, we used five AI/ML algorithms, including deep neural network and GUIDE. Results: Of the four maximum severity groups, the moderate group had the highest percentage (1,115 patients; 49.5%). As factors contributing to exacerbation of maximum severity, there were 25 statistically significant predictors through simple analysis of linear trends. As a result of model development, the following three models based on binary classification showed high predictive performance: (1) Mild vs. Above Moderate, (2) Below Moderate vs. Above Severe, and (3) Below Severe vs. Critical. The performance of these three binary models was evaluated using AUC values 0.883, 0.879, and, 0.887, respectively. Based on results for each of the three predictive models, we developed web-based nomograms for clinical use (http://statgen.snu.ac.kr/software/nomogramDaeguCovid/). Conclusions: We successfully developed web-based nomograms predicting the maximum severity. These nomograms are expected to help plan an effective treatment for each patient in the clinical field. | Hwangbo, Suhyun; Kim, Yoonjung; Lee, Chanhee; Lee, Seungyeoun; Oh, Bumjo; Moon, Min Kyong; Kim, Shin-Woo; Park, Taesung | Seoul Natl Univ, Interdisciplinary Program Bioinformat, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Genom Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Sejong Univ, Dept Math & Stat, Seoul, South Korea; Seoul Metropolitan Govt Seoul Natl Univ, Boramae Med Ctr, Dept Family Med, Seoul, South Korea; Seoul Metropolitan Govt Seoul Natl Univ, Boramae Med Ctr, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Dept Stat, Seoul, South Korea | Oh, Bumjo/O-2462-2017; Kim, Ji Hoon/AAB-4602-2022; Oh, Bumjo/GWN-2776-2022; Moon, Min/AAE-7663-2020 | 57208262466; 57203160508; 57219941916; 15754275000; 55272690200; 36123604500; 8710731500; 34668299500 | ksw2kms@knu.ac.kr;tspark@stats.snu.ac.kr; | FRONTIERS IN PUBLIC HEALTH | FRONT PUBLIC HEALTH | 2296-2565 | 10 | SCIE;SSCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 5.2 | 13.6 | 1.28 | 2025-06-25 | 9 | 10 | COVID-19; artificial intelligence; machine learning; severity; nomogram | C-REACTIVE PROTEIN; SELECTION | artificial intelligence; COVID-19; machine learning; nomogram; severity | Artificial Intelligence; COVID-19; Hospitalization; Humans; Machine Learning; Neural Networks, Computer; artificial intelligence; epidemiology; hospitalization; human; machine learning | English | 2022 | 2022-11-28 | 10.3389/fpubh.2022.1007205 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Measuring Perceived Psychological Stress in Urban Built Environments Using Google Street View and Deep Learning | An urban built environment is an important part of the daily lives of urban residents. Correspondingly, a poor design can lead to psychological stress, which can be harmful to their psychological and physical well-being. The relationship between the urban built environment and the perceived psychological stress of residents is a significant in many disciplines. Further research is needed to determine the stress level experienced by residents in the built environment on a large scale and identify the relationship between the visual components of the built environment and perceived psychological stress. Recent developments in big data and deep learning technology mean that the technical support required to measure the perceived psychological stress of residents has now become available. In this context, this study explored a method for a rapid and large-scale determination of the perceived psychological stress among urban residents through a deep learning approach. An empirical study was conducted in Gangnam District, Seoul, South Korea, and the SegNet deep learning algorithm was used to segment and classify the visual elements of street views. In addition, a human-machine adversarial model using random forest as a framework was employed to score the perception of the perceived psychological stress in the built environment. Consequently, we found a strong spatial autocorrelation in the perceived psychological stress in space, with more low-low clusters in the urban traffic arteries and riverine areas in Gangnam district and more high-high clusters in the commercial and residential areas. We also analyzed the street view images for three types of stress perception (i.e., low, medium and high) and obtained the percentage of each street view element combination under different stresses. Using multiple linear regression, we found that walls and buildings cause psychological stress, whereas sky, trees and roads relieve it. Our analytical study integrates street view big data with deep learning and proposes an innovative method for measuring the perceived psychological stress of residents in the built environment. The research methodology and results can be a reference for urban planning and design from a human centered perspective. | Han, Xin; Wang, Lei; Seo, Seong Hyeok; He, Jie; Jung, Taeyeol | Kyungpook Natl Univ, Dept Landscape Architecture, Daegu, South Korea; Tianjin Univ, Sch Architecture, Tianjin, Peoples R China; Harbin Inst Technol Shenzhen, Sch Architecture, Shenzhen, Peoples R China | ; He, Jie/O-6948-2019; He, Jie/P-1494-2014; 磊, 王/KFS-1412-2024 | 57716224500; 57715975800; 57716224600; 57221314854; 55490551100 | hejie2021@hit.edu.cn;jungty@knu.ac.kr; | FRONTIERS IN PUBLIC HEALTH | FRONT PUBLIC HEALTH | 2296-2565 | 10 | SCIE;SSCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 5.2 | 13.6 | 7.82 | 2025-06-25 | 54 | 63 | deep learning; Google Street View; semantic segmentation; perceived psychological stress; built environment | HEALTH; COMPLEXITY; LANDSCAPE | built environment; deep learning; Google Street View; perceived psychological stress; semantic segmentation | Built Environment; Deep Learning; Humans; Republic of Korea; Search Engine; Stress, Psychological; human; mental stress; search engine; South Korea | English | 2022 | 2022-05-11 | 10.3389/fpubh.2022.891736 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Robust input/output model matching of asynchronous sequential machines under intermittent actuator faults | A robust model matching control scheme for input/output asynchronous sequential machines (ASMs) with intermittent actuator faults is presented in the framework of corrective control. In our problem setting, certain actuator outputs are not transmitted to the machine temporarily owing to random faults. We first present a state observer that predicts the current stable state of the machine based on the output burst and control input, as well as diagnoses actuator faults. We then address the existence condition and design procedure for an output-feedback corrective controller that matches the input/output behavior of the closed-loop system to that of a reference model against intermittent loss of actuator outputs. To demonstrate the applicability of the proposed control method, we implement a practical asynchronous digital system with the developed corrective controller on the field-programmable gate array (FPGA) circuit. Experimental verifications using the FPGA circuit are also provided.(c) 2022 The Franklin Institute. Published by Elsevier Ltd.

| ○ | ○ | Article | Use of video-based telehealth services using a mobile app for workers in underserved areas during the COVID-19 pandemic: A prospective observational study | Background: The COVID-19 pandemic has limited face-to-face treatment, triggering a change in the structure of existing healthcare services. Unlike other groups, workers in underserved areas have relatively poor access to healthcare. Objective: This study aimed to investigate the effects of video-based telehealth services using a mobile personal health record (PHR) app for vulnerable workers with metabolic risk factors. Methods: A prospective observational study was conducted with 117 participants and 27 healthcare professionals for 16 weeks. Participants visited the research institution three times (at weeks 1, 8, and 16) and underwent health check-ups and used various features of the mobile PHR app. Healthcare professionals observed the participants data using the monitoring system and performed appropriate interventions. The primary outcome measures were to evaluate the effects of services on changes in the participants metabolic risk factors, and secondary outcome measures were to analyze changes in the participants lifestyle and service satisfaction, and to observe service use through usage logs. One-way repeated measures ANOVA and Scheffe's test were performed to observe changes in participants health status and lifestyle, and a paired t-test was performed to analyze changes in service satisfaction. Finally, in-depth interviews with healthcare professionals were performed using semi-structured questionnaires to understand service providers & rsquo; perspectives after the end of the study. Results: Systolic blood pressure (F = 7.32, P <.001), diastolic blood pressure (F = 11.30, P < 001), body weight (F = 29.53, P < .001), BMI (F = 17.31, P < .001), waist circumference (F =17.33, P < .001), fasting blood glucose (F = 5.11, P =.007), and triglycerides (F = 4.66, P =.01) showed significant improvements with time points, whereas high-density lipoprotein cholesterol (F = 3.35, P =.067) did not. The dietary score (F = 3.26, P =.04) showed a significant improvement with time points, whereas physical activity (F = 1.06, P =.34) did not. In terms of service satisfaction, only lifestyle improvement (P < .001) showed a significant difference. COVID-19 has affected the performance of healthcare professionals, thereby changing the perspectives toward healthcare technology services. Conclusions: We evaluated the effectiveness of video-based telehealth services supporting workers health status and lifestyle interventions using healthcare technologies such as the mobile PHR app, tele-monitoring, and video teleconsultation. Our results indicate that as a complementary means, its utility can be expanded in the field of occupational safety and health to overcome the limitations of face-to-face treatment due to COVID-19 in the future. | Park, Hyun Sang; Jeong, Sungmoon; Chung, Ho-young; Soh, Jae Young; Hyun, Young Ho; Bang, Seong Hwan; Kim, Hwa Sun | BIT Comp Co Ltd, Digital Healthcare Dept, Seoul, South Korea; Kyungpook Natl Univ, Dept Med Informat, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Surg, Daegu, South Korea; Elecmarvels Co Ltd, Daegu, South Korea | ; Park, HyunSang/KSM-9402-2024 | 56623579700; 23100090400; 56008255800; 54791376600; 57217131020; 57856582000; 59052965400 | hychung@knu.ac.kr; | INTERNATIONAL JOURNAL OF MEDICAL INFORMATICS | INT J MED INFORM | 1386-5056 | 1872-8243 | 166 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;HEALTH CARE SCIENCES & SERVICES;MEDICAL INFORMATICS | 2022 | 4.9 | 13.7 | 0.42 | 2025-06-25 | 5 | 5 | Video -based telehealth service; Mobile personal health record app; COVID-19; Metabolic risk factors; Prospective observational study | TIME PHYSICAL-ACTIVITY; METABOLIC SYNDROME; DIABETES CARE; INTERVENTIONS; TELEMEDICINE; HEALTH; ADULTS; METAANALYSIS; LESSONS; DISEASE | COVID-19; Metabolic risk factors; Mobile personal health record app; Prospective observational study; Video-based telehealth service | Blood Glucose; Cholesterol; COVID-19; Humans; Lipoproteins, HDL; Medically Underserved Area; Mobile Applications; Pandemics; Remote Consultation; Triglycerides; Blood; Blood pressure; Health risks; Medical computing; Metabolism; mHealth; Monitoring; Risk assessment; Surveys; glucose; high density lipoprotein cholesterol; triacylglycerol; cholesterol; high density lipoprotein; triacylglycerol; Metabolic risk factor; Mobile personal health record app; Observational study; Personal health record; Prospective observational study; Prospectives; Risk factors; Telehealth services; Video-based telehealth service; Workers'; adult; Article; body mass; body weight; clinical outcome; coronavirus disease 2019; diastolic blood pressure; employment status; female; glucose blood level; health care personnel; health service; health status; high density lipoprotein cholesterol level; human; international physical activity questionnaire; interview; lifestyle; major clinical study; male; medical examination; medical record; medically underserved; observational study; occupational health service; outcome assessment; pandemic; patient satisfaction; physical activity; prospective study; risk factor; structured questionnaire; systolic blood pressure; teleconsultation; telehealth; triacylglycerol blood level; videorecording; waist circumference; epidemiology; health care planning; mobile application; teleconsultation; COVID-19 | English | 2022 | 2022-10 | 10.1016/j.ijmedinf.2022.104844 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A predictive SO(10) model | We discuss some testable predictions of a non-sup ersymmetric SO(10) model supplemented by a Peccei-Quinn symmetry. We utilize a symmetry breaking pattern of SO(10) that yields unification of the Standard Model gauge couplings, with the unification scale also linked to inflation driven by an SO(10) singlet scalar field with a Coleman-Weinberg potential. Proton decay mediated by the superheavy gauge bosons may be observable at the proposed Hyper-Kamiokande experiment. Due to an unbroken Z2 gauge symmetry from SO(10), the model predicts the presence of a stable intermediate mass fermion which, together with the axion, provides the desired relic abundance of dark matter. The model also predicts the presence of intermediate scale topologically stable monopoles and strings that survive inflation. The monopoles may be present in the Universe at an observable level. We estimate the stochastic gravitational wave background emitted by the strings and show that it should be testable in a number of planned and proposed space and land based experiments. Finally, we show how the observed baryon asymmetry in the Universe is realized via non-thermal leptogenesis. | Lazarides, George; Maji, Rinku; Roshan, Rishav; Shafi, Qaisar | Aristotle Univ Thessaloniki, Fac Engn, Sch Elect & Comp Engn, Thessaloniki 54124, Greece; Phys Res Lab, Theoret Phys Div, Ahmadabad 380009, India; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Univ Delaware, Bartol Res Inst, Dept Phys & Astron, Newark, DE 19716 USA | 7004661081; 57202461840; 57211218592; 7004752140 | glazarid@gen.auth.gr;rinkumaji9792@gmail.com;rishav.roshan@gmail.com;qshafi@udel.edu; | JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS | J COSMOL ASTROPART P | 1475-7516 | 12 | SCIE | ASTRONOMY & ASTROPHYSICS;PHYSICS, PARTICLES & FIELDS | 2022 | 6.3 | 13.8 | 1.22 | 2025-06-25 | 17 | 15 | Cosmic strings; domain walls; monopoles; dark matter theory; inflation; leptogenesis | RENORMALIZATION-GROUP EQUATIONS; GRAND UNIFIED THEORIES; QUANTUM-FIELD THEORY; SUPERSYMMETRIC PROTON-DECAY; GRAVITATIONAL-RADIATION; ENHANCEMENT FACTORS; PHASE-TRANSITIONS; CP CONSERVATION; DARK-MATTER; UNIFICATION | Cosmic strings; dark matter theory; domain walls; inflation; leptogenesis; monopoles | English | 2022 | 2022-12 | 10.1088/1475-7516/2022/12/009 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Axion as a fuzzy dark matter candidate: proofs in different gauges | Axion as a coherently oscillating massive scalar field is known to behave as a zero pressure irrotational fluid with characteristic quantum stress on a small scale. In relativistic perturbation theory, the case was proved in the axion-comoving gauge up to fully nonlinear and exact order. Our basic assumption is that the field is oscillating with Compton frequency and the Compton wavelength is smaller than the horizon scale. Here, we revisit the relativistic proof to the linear order in the other gauge conditions. We show that the same equation for density perturbation known in the non-relativistic treatment can be derived in two additional gauge conditions: the zero-shear gauge and the uniform-curvature gauge. The uniform expansion gauge fails to get the aimed equation, and the quantum stress term is missing in the synchronous gauge. For comparison, we present the relativistic density perturbation equations in the zero-pressure fluid in these gauge conditions. Except for the comoving and the synchronous gauge, the equations strikingly differ from the axion case. We clarify that the relativistic analysis based on time averaging is valid for scales larger than the Compton wavelength. Below the Compton wavelength, the field is not oscillating, and our oscillatory ansatz does not apply. We suggest an equation valid in all scales in the comoving gauge. For comparison, we review the non-relativistic quantum hydrodynamics and present the Schrodinger equation to first-order post-Newtonian expansion in the cosmological context.

| ○ | ○ | Article | Cogenesis of Baryon asymmetry and gravitational dark matter from primordial black holes | We propose a scenario where dark matter (DM) with a wide mass range from a few keV to PeV can be produced solely from evaporating primordial black holes (PBH), while being consistent with the required free streaming length for structure formation. If DM does not have any other interactions apart from gravity and the universe has a PBH dominated phase at early epoch, then PBH evaporation typically leads to overproduction of DM in this mass range. By incorporating this gravitational DM within a Type-I seesaw scenario with three right handed neutrinos (RHN), we bring the abundance of PBH generated DM within observed limits by late entropy injection due to decay of one of the RHNs, acting as the diluter. The diluter, due to its feeble coupling with the bath particles, gets produced primarily from the PBH evaporation thereby leading to the second stage of early matter domination after the end of PBH dominated era. The other two RHNs contribute to the origin of light neutrino mass and also lead to the observed baryon asymmetry via leptogenesis with contributions from both thermally and PBH generated RHNs. The criteria of DM relic and baryon asymmetry can be satisfied simultaneously if DM mass gets restricted to a ballpark in the MeV-GeV regime with the requirement of resonant leptogenesis for heavier DM mass in order to survive the large entropy dilution at late epochs. | Barman, Basabendu; Borah, Debasish; Das, Suruj Jyoti; Roshan, Rishav | Univ Antonio Narino, Ctr Invest, Carrera 3 Este 47A-15, Bogota, Colombia; Indian Inst Technol Guwahati, Dept Phys, Gauhati 781039, Assam, India; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea | ; Barman, Basabendu/AGN-9952-2022; Borah, Debasish/K-8411-2016 | 57200142752; 37005361300; 57219732669; 57211218592 | basabendu88barman@gmail.com;dborah@iitg.ac.in;suruj@iitg.ac.in;rishav.roshan@gmail.com; | JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS | J COSMOL ASTROPART P | 1475-7516 | 8 | SCIE | ASTRONOMY & ASTROPHYSICS;PHYSICS, PARTICLES & FIELDS | 2022 | 6.3 | 13.8 | 1.46 | 2025-06-25 | 20 | 18 | primordial black holes; dark matter theory; leptogenesis | PARTICLE-PRODUCTION; NEUTRINO MASS; CREATION; LEPTOGENESIS; EVAPORATION | dark matter theory; leptogenesis; primordial black holes | English | 2022 | 2022-08 | 10.1088/1475-7516/2022/08/068 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Dahl salt-resistant rats are protected against angiotensin II-induced hypertension | Angiotensin II is a potent endogenous vasoconstrictor that induces oxidative stress in hypertensive rodent models. Dahl salt-resistant (SR) rats are protected against hypertension after high salt or high fructose intake. However, whether these rats are also protected against angiotensin II-mediated hypertension has not been investigated. Dahl salt-sensitive (SS) and SR rats were infused with angiotensin II (10 or 50 ng/kg/min) or vehicle via a mini-osmotic pump for 2 weeks. Blood pressure was measured using the tail-cuff method. Paraffin sections of the thoracic aortas and kidneys were stained using hematoxylin/eosin or Masson trichrome. Renal gene expression was measured using reverse transcription-quantitative polymerase chain reaction. Angiotensin II (50 ng/kg/min) induced hypertension in SS rats, but not in SR rats, although low doses of angiotensin II (10 ng/kg/min) transiently increased blood pressure in SS rats. Angiotensin II (50 ng/kg/min) did not induce morphological changes in the aortic walls or kidneys. Angiotensin II (50 ng/kg/min) induced the expression of At1rb, Nox2, Il-17ra, Il-23r, Tgf-beta, Il-1 beta and Il-6 in SS rats, but not in SR rats. In conclusion, SR rats were protected against angiotensin II-induced hypertension. This result implies that the genetic trait that determines salt sensitivity may also determine susceptibility to hypertension in response to vasoconstrictors. | Kim, Cheong-Wun; Kim, Jee Young; Lee, Soyung; Kim, Inkyeom | Kyungpook Natl Univ, Sch Med, Dept Pharmacol, Daegu 41944, South Korea; Kyungpook Natl Univ, Cardiovasc Res Inst, Sch Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu 41944, South Korea | 56662531400; 57867619100; 57867559800; 7404144630 | inkim@knu.ac.kr; | BIOCHEMICAL PHARMACOLOGY | BIOCHEM PHARMACOL | 0006-2952 | 1873-2968 | 203 | SCIE | PHARMACOLOGY & PHARMACY | 2022 | 5.8 | 13.8 | 0.59 | 2025-06-25 | 6 | 6 | Hypertension; Angiotensin II; Immune response; Dahl salt-sensitive rat; Dahl salt-resistant rat; End-organ damage | OXIDATIVE STRESS; RENAL INJURY; ANG-II; RECEPTOR; KIDNEY; CELLS; MICE; DIFFERENTIATION; EXPRESSION; INDUCTION | Angiotensin Ⅱ; Dahl salt-resistant rat; Dahl salt-sensitive rat; End-organ damage; Hypertension; Immune response | Angiotensin II; Animals; Blood Pressure; Hypertension; Kidney; Rats; Rats, Inbred Dahl; Sodium Chloride; Sodium Chloride, Dietary; Vasoconstrictor Agents; angiotensin II; interleukin 17 receptor; interleukin 1beta; interleukin 23 receptor; interleukin 6; paraffin; reduced nicotinamide adenine dinucleotide phosphate oxidase 2; transforming growth factor beta; angiotensin II; sodium chloride; vasoconstrictor agent; adaptive immunity; animal experiment; animal model; animal tissue; arterial wall thickness; Article; blood pressure measurement; controlled study; Dahl salt resistant rat; Dahl salt sensitive rat; drug effect; gene expression; genetic trait; histopathology; hypertension; immunocompetent cell; innate immunity; kidney fibrosis; low drug dose; Masson staining; mRNA expression level; nonhuman; protein expression; protein expression level; rat; real time reverse transcription polymerase chain reaction; regulatory T lymphocyte; systolic blood pressure; Th17 cell; thoracic aortic wall; thorax wall; adverse event; animal; blood pressure; Dahl rat; genetics; hypertension; kidney; metabolism; salt intake | English | 2022 | 2022-09 | 10.1016/j.bcp.2022.115193 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Perfusion profile evaluated by severity-weighted multiple Tmax strata predicts early neurological deterioration in minor stroke with large vessel occlusion | Minor stroke due to large vessel occlusion (LVO) is associated with poor outcomes. Hypoperfused tissue fate may be more accurately predicted by severity-weighted multiple perfusion strata than by a single perfusion threshold. We investigated whether poor perfusion profile evaluated by multiple Tmax strata is associated with early neurological deterioration (END) in patients with minor stroke with LVO. Ninety-four patients with a baseline National Institute of Health Stroke Scale score 10 s) against the entire hypoperfusion volume (Tmax >2 s) were measured. The perfusion profile was defined as the shift of the distribution of the Tmax strata proportions towards worse hypoperfusion severity compared with that of the entire cohort using the Wilcoxon-Mann-Whitney generalised odds ratio (OR); its performance to predict END was tested. The area under the curve of perfusion profile was 0.785 (95% confidence interval [CI]: 0.691-0.878, p 1.052) was independently associated with END (adjusted OR 13.42 [95% CI: 4.38-41.15], p < 0.001). Thus, perfusion profile with severity-weighted multiple Tmax strata may predict END in minor stroke and LVO. | Gwak, Dong-Seok; Choi, WooChan; Kwon, Jung-A; Shim, Dong-Hyun; Kim, Yong-Won; Hwang, Yang-Ha | Kyungpook Natl Univ Hosp, Dept Neurol, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea | ; HWANG, Yang-Ha/F-3068-2013 | 57205148053; 57225111001; 57220198799; 56779672200; 56203298200; 7402311308 | yangha.hwang@gmail.com; | JOURNAL OF CEREBRAL BLOOD FLOW AND METABOLISM | J CEREBR BLOOD F MET | 0271-678X | 1559-7016 | 42 | 2 | SCIE | ENDOCRINOLOGY & METABOLISM;HEMATOLOGY;NEUROSCIENCES | 2022 | 6.3 | 13.8 | 0.81 | 2025-06-25 | 9 | 7 | Cerebral infarction; clinical deterioration; magnetic resonance imaging; perfusion imaging; stroke | ACUTE ISCHEMIC-STROKE; INTRAVENOUS THROMBOLYSIS; MECHANICAL THROMBECTOMY; COLLATERAL STATUS; INFARCT GROWTH; MILD; OUTCOMES; SYMPTOMS; MISMATCH; TISSUE | Cerebral infarction; clinical deterioration; magnetic resonance imaging; perfusion imaging; stroke | Aged; Aged, 80 and over; Brain; Cerebrovascular Circulation; Diffusion Magnetic Resonance Imaging; Female; Humans; Male; Middle Aged; Retrospective Studies; Stroke; aged; Article; blood vessel occlusion; brain infarction; brain perfusion; cerebrovascular accident; clinical outcome; controlled study; deterioration; diffusion weighted imaging; disease severity; erythrocyte sedimentation rate; human; internal carotid artery; magnetic resonance angiography; major clinical study; male; moyamoya disease; National Institutes of Health Stroke Scale; nuclear magnetic resonance imaging; Rankin scale; recanalization; receiver operating characteristic; retrospective study; sensitivity and specificity; smoking; brain; brain circulation; diagnostic imaging; diffusion weighted imaging; female; middle aged; pathophysiology; vascularization; very elderly | English | 2022 | 2022-02 | 10.1177/0271678x211029165 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Towards REDD plus implementation: Deforestation and forest degradation drivers, REDD plus financing, and readiness activities in participant countries | This study provides an assessment of dominant drivers of deforestation and forest degradation across 29 REDD+ participant countries and total funds disbursed from the Forest Carbon Partnership Facility to 15 participant countries since they signed their respective Readiness Preparation Proposals (R-PPs), as well as what they spent the grants on. This study aims to provide information for policymakers and donors on the need to invest in REDD+, as well as the need for participant countries to channel funds to key activities for effectively and efficiently implementing REDD+. The assessment is based on participant countries' R-PPs and FCPF readiness fund progress reports, using a content analysis approach. The expansion of agriculture, which includes both commercial and subsistence agriculture, was the predominant driver of deforestation, while logging, such as industrial and small-scale exploitation, was the main driver of forest degradation in most participating countries. In addition, we observed that the 15 participant countries received a total of USD 702.36 million for REDD+ readiness preparation. However, most countries have received less than USD 10 million for their readiness-related activities. We observed a huge disparity regarding the funds received between countries from sub-Saharan Africa and their Asian and Latin American counterparts, particularly Indonesia and Peru, respectively. Furthermore, almost all countries have spent their funds on policy and strategy development, stakeholder and consultation events, and public awareness creation. Relatively small amounts have been spent on capacity building and training. Thus, international donors need to focus on strengthening institutional capacities and building effective forest governance structures in countries participating in REDD+, and they should also provide platforms to engage with participant countries to tackle the main deforestation and forest degradation drivers. We suggest further studies to identify high-performing countries that have received lower-than-average funding, consider their deforestation pressures, the size of forests, and the emission reduction potential. | Andoh, Jewel; Oduro, Kwame Antwi; Park, Joowon; Lee, Yohan | Forestry Res Inst Ghana, CSIR, Kumasi, Ghana; Kyungpook Natl Univ, Sch Forestry Sci & Landscape Architecture, Daegu, South Korea; Seoul Natl Univ, Dept Agr Forestry & Bioresources, Seoul, South Korea | Lee, Yo/J-1911-2019 | 57196952122; 57200388159; 55791550500; 57034503000 | johnlee@snu.ac.kr; | FRONTIERS IN FORESTS AND GLOBAL CHANGE | FRONT FOR GLOB CHANG | 2624-893X | 5 | SCIE | ECOLOGY;FORESTRY | 2022 | 3.2 | 13.8 | 1.64 | 2025-06-25 | 13 | 14 | drivers of deforestation and forest degradation; REDD plus; readiness preparation proposal (R-PP); funding; stakeholder engagement; participant country | AGRICULTURAL INTENSIFICATION; POPULATION-GROWTH; LEVEL | drivers of deforestation and forest degradation; funding; participant country; readiness preparation proposal (R-PP); REDD+; stakeholder engagement | English | 2022 | 2022-10-18 | 10.3389/ffgc.2022.957550 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Zinc-dependent histone deacetylases: Potential therapeutic targets for arterial hypertension | The pathogenesis of hypertension caused by various genetic and environmental factors has not been elucidated. Clinical trials have evaluated various anti-hypertensive drugs with different therapeutic mechanisms. Due to the increasing prevalence of hypertension in the aging population and appearance of adverse effects, novel anti-hypertensive drugs need be developed. Histone deacetylases (HDACs), a group of enzymes which have recently attracted attention, are dysregulated in several cancers and cardiovascular diseases. Mammalian HDACs are categorized into four classes: class I HDAC (HDAC1, 2, 3, 8), class IIa HDAC (HDAC4, 5, 7, 9), class IIb HDAC (HDAC6, 10), and class IV HDAC (HDAC11) are zinc-dependent enzymes, while class III HDACs are nicotinamide adenine dinucleotide (NAD)-dependent enzymes. In this review, we focused on the pharmacological inhibitors of zinc-dependent HDACs used for controlling hypertension. We addressed the biological effects and underlying mechanisms of isoform-selective, class HDAC-selective, or pan-HDAC inhibitors on various hypertensive animal models (angiotensin II infusion mice, deoxycorticosterone acetate-salt-induced rats, spontaneously hypertensive rats, high-fat diet-treated mice, and nitric oxide (NO)-deficient mice) and HDAC5 deletion mice. We discuss the cardiovascular phenotypes of class I and IIa/b HDAC-deficient mice and potential adverse effects of HDAC inhibitors in preclinical studies. This review summarizes recent studies on synthetic or dietary HDAC inhibitors (sulforaphane, gallic acid, and curcumin) that alleviate hypertension by the regulating renin-angiotensin-aldosterone system, vascular hypertrophy, vasoconstriction, inflammation, or oxidative stress. Although the phenotypic analysis of hypertension in isoform HDAC deletion mice is required, few HDACs (HDAC3, HDAC4, and HDAC8) are promising therapeutic targets for treating hypertension. | Kee, Hae Jin; Kim, Inkyeom; Jeong, Myung Ho | Chonnam Natl Univ Hosp, Heart Res Ctr, 42 Jebong ro, Gwangju 61469, South Korea; Chonnam Natl Univ Hosp, Hypertens Heart Failure Res Ctr, Gwangju 61469, South Korea; Kyungpook Natl Univ, BK21 Plus KNU Biomed Convergence Program, Cardiovasc Res Inst, Dept Pharmacol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, Daegu 41944, South Korea; Chonnam Natl Univ, Sch Med, Dept Cardiol, Gwangju 61469, South Korea | Kee, Hae Jin/ABC-9979-2021 | 57205335989; 7404144630; 56485157500 | sshjkee@empas.com;myungho@chollian.net; | BIOCHEMICAL PHARMACOLOGY | BIOCHEM PHARMACOL | 0006-2952 | 1873-2968 | 202 | SCIE | PHARMACOLOGY & PHARMACY | 2022 | 5.8 | 13.8 | 1.2 | 2025-06-25 | 29 | 29 | Histone deacetylase; Histone deacetylase inhibitor; Dietary histone deacetylase inhibitor; Hypertension | II-INDUCED HYPERTENSION; VALPROIC ACID; CARDIAC-HYPERTROPHY; OXIDATIVE STRESS; GENE-EXPRESSION; BLOOD-PRESSURE; GALLIC ACID; TRANSCRIPTIONAL ACTIVITY; TRICHOSTATIN-A; NUCLEAR EXPORT | Dietary histone deacetylase inhibitor; Histone deacetylase; Histone deacetylase inhibitor; Hypertension | Animals; Antihypertensive Agents; Histone Deacetylase Inhibitors; Histone Deacetylases; Hypertension; Mammals; Mice; Protein Isoforms; Rats; Zinc; angiotensin II; curcumin; deoxycorticosterone acetate; gallic acid; histone deacetylase; histone deacetylase 5; histone deacetylase inhibitor; nitric oxide; sulforaphane; unclassified drug; zinc; zinc dependent histone deacetylase; antihypertensive agent; Hdac5 protein, rat; histone deacetylase; histone deacetylase inhibitor; isoprotein; zinc; biological activity; deoxycorticosterone-salt-induced hypertension; disease control; drug targeting; endothelium cell; heart hypertrophy; human; hypertension; inflammation; lipid diet; nonhuman; oxidative stress; phenotype; preclinical study; renin angiotensin aldosterone system; Review; spontaneously hypertensive rat; upregulation; vascular remodeling; vasoconstriction; vasodilatation; animal; genetics; mammal; mouse; pathology; rat | English | 2022 | 2022-08 | 10.1016/j.bcp.2022.115111 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Blockchain-Envisioned Provably Secure Multivariate Identity-Based Multi-Signature Scheme for Internet of Vehicles Environment | The deployed vehicles in an Internet of Vehicles (IoV) can take intelligent decisions by means of exchanging the real-time traffic-related information between the vehicles and IoV infrastructures. This further reduces the probability of the traffic jams and accidents. However, the insecure (public) communication among the various entities in IoV makes various security threats and attacks that can be launched by passive/active adversaries present in the network. In view of this context, there is a need of an efficient cryptographic primitive which can produce single compact signature. A multi-signature scheme (MSS) empowers a collection of signers to conjointly sign a given message using a single compact signature that can be verified by any verifier. Herein, we put forward a new identity-based multivariate MSS, namely MV-MSS, which is built on top of the intractability of multivariate-quadratic (MQ) problem. The fact is that multivariate public key cryptosystem provides fast, post-quantum safe and efficient primitives, which makes it the front runner candidate among the post-quantum cryptographic candidates. MV-MSS is proven to be secure in the existential unforgeability under chosen-message and chosen identity attack model if solving the MQ problem is NP-hard. We then incorporate the designed MV-MSS in IoV application where the leader (cluster head) selected from a group of vehicles in a dynamic cluster forms the multi-signatures on the messages securely received from its member vehicles. Later, the messages along with their multi-signatures are forwarded to the nearby road-side unit (RSU) of the cluster head, which are then forwarded to a cloud server in the blockchain center maintained by a Peer-to-Peer (P2P) cloud servers network. In this way, the messages and their signatures considered as transactions are put in blocks and added into a public blockchain with the help of consensus algorithm. A comparative study among the proposed MV-MSS and other existing schemes shows that MV-MSS is efficient and secure as compared to other schemes. Finally, a blockchain implementation through simulation study has been performed to show its practical use in IoV application. | Srivastava, Vikas; Debnath, Sumit Kumar; Bera, Basudeb; Das, Ashok Kumar; Park, Youngho; Lorenz, Pascal | Natl Inst Technol, Dept Math, Jamshedpur 831014, Bihar, India; Int Inst Informat Technol, Ctr Secur Theory & Algorithm Res, Hyderabad 500032, India; Old Dominion Univ, Virginia Modeling Anal & Simulat Ctr, Suffolk, VA 23435 USA; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Univ Haute Alsace, F-68100 Mulhouse, France | ; DEBNATH, SUMIT/AAB-6425-2019; Bera, Basudeb/ACC-6233-2022; , LORENZ/ABH-9737-2020; Das, Ashok Kumar/U-2790-2019 | 57351589400; 56562621700; 57214777647; 55450732800; 56962990300; 7101942080 | vikas.math123@gmail.com;sdebnath.math@nitjsr.ac.in;basudeb.bera@research.iiit.ac.in;shok.das@iiit.ac.in;parkyh@knu.ac.kr;lorenz@ieee.org; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 71 | 9 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2022 | 6.8 | 14.0 | 2.72 | 2025-06-25 | 23 | 31 | Blockchains; Cryptography; Servers; Electronic mail; Roads; Aggregates; Vehicle dynamics; Internet of Vehicles (IoV); identity-based cryptography; multi-signature; Blockchain; consensus; security | AGGREGATE; PROTOCOL; LATTICE | Blockchain; consensus; identity-based cryptography; Internet of Vehicles (IoV); multi-signature; security | Authentication; Distributed computer systems; Network security; Public key cryptography; Roads and streets; Topology; Traffic congestion; Vehicles; Block-chain; Consensus; Identity based cryptography; Internet of vehicle; Multi-signature; Multisignature scheme; Road; Security; Vehicle's dynamics; Blockchain | English | 2022 | 2022-09 | 10.1109/tvt.2022.3176755 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Data-Driven Leading Vehicle Speed Forecast and Its Application to Ecological Predictive Cruise Control | In this article, we propose an ecological predictive cruise control method for connected and automated vehicles (CAVs) using data-driven predicted leading vehicle speed in a car-following scenario. Many existing studies assume that the leading vehicle's behavior is known when planning the trajectory of the ego vehicle. Unfortunately, predicting the future behavior of adjacent vehicles is extremely uncertain and inaccurate for use in control. To overcome this, we adopt the vector autoregressive model (VAR) that is well suited for generating simultaneous forecasts of the response variables when predicting the short-term behavior of the vehicle ahead. As many human drivers behave similarly in a car-following situation, vehicle connectivity is specifically used to drop hints of the behaviors of the cars following the connected car. Once the leading vehicle's future trajectory is predicted, the ego vehicle is controlled in a way that minimizes energy consumption by optimizing its speed trajectory while remaining safe. Through simulation case studies, we demonstrate that our approach can achieve improved energy efficiency considerably than the conventional strategy that cannot predict the speed of vehicles ahead. Given the recent market penetration of vehicle connectivity technologies and advanced driving assistance systems (ADAS), the proposed method is expected to have a high commercialization potential. | Sankar, Gokul S.; Kim, Minwoo; Han, Kyoungseok | Kyungpook Natl Univ, Inst Mech Engn Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | 55326286700; 57275023500; 56465294700 | gokul.sivasankar@gmail.com;kimminw3@msu.edu;kyoungsh@knu.ac.kr; | IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY | IEEE T VEH TECHNOL | 0018-9545 | 1939-9359 | 71 | 11 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;TRANSPORTATION SCIENCE & TECHNOLOGY | 2022 | 6.8 | 14.0 | 1.05 | 2025-06-25 | 12 | 12 | Connected and Automated Vehicles; Receding-horizon Control; Adaptive Cruise Control; and Speed Forecasting | STRATEGY | Adaptive Cruise Control; and Speed Forecasting; Connected and Automated Vehicles; Receding-horizon Control | Adaptive cruise control; Automobile drivers; Behavioral research; Ecology; Energy efficiency; Energy utilization; Forecasting; Trajectories; Vehicles; And speed forecasting; Automated vehicles; Battery; Behavioral science; Car following; Connected and automated vehicle; Connected vehicle; Leading vehicle; Receding horizon control; Road; Speed | English | 2022 | 2022-11 | 10.1109/tvt.2022.3193091 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
