| ○ | Article | H2 Gas Sensor Based on Pd-Loaded Carbon Nanotube Film | Palladium-coated multi-walled carbon nanotube (Pd-MWCNT) nanocomposites have been experimentally proven to show highly improved hydrogen (H-2) gas detection characteristics at room temperature when compared with single MWCNTs. In this context, we develop an efficient and convenient method for forming nanocomposites by coating Pd nanoparticles on an MWCNT film. Furthermore, we test the applicability of the nanocomposites as sensing materials in detecting H-2 gas at room temperature in a reliable and sensitive manner in contrast with ordinary metal-oxide based gas sensors that operate at high temperatures. We first study the detection efficacy of the Pd-MWCNT film relative to, pure MWCNT film. Subsequently, we investigate the Pd-MWCNT sensor's sensitivity over time for different gas concentrations, the sensor response time, and sensor reproducibility and reliability under various conditions including bending tests. Our sensor exhibits stable reliable detection characteristics and excellent structural flexibility. | Han, Maeum; Kim, Jae Keon; Lee, Junyeop; An, Hee Kyung; Yung, Jong Pil; Kang, Shin-Won; Jung, Daewoong | Kyungpook Natl Univ, Coll IT Engn, Sch Elect Engn, Daegu 41566, South Korea; Korea Inst Ind Technol KITECH, AI Syst Engn Grp, Daegu 42994, South Korea; Korea Inst Ind Technol KITECH, Mechatron Technol Convergence R&D Grp, Daegu 42994, South Korea; Kyungpook Natl Univ, Dept Sensor & Display Engn, Daegu 41566, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 7 | 5 | Carbon Nanotube; Hydrogen; Palladium; Gas Sensor; Spill-Over | HYDROGEN SENSOR; PERFORMANCE | English | 2020 | 2020-07 | 10.1166/jnn.2020.17608 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | ○ | Article | Health-Related Quality of Life Based on Comorbidities Among Patients with End-Stage Renal Disease | Objectives: The aim of this study was to investigate comorbidities in patients with end-stage renal disease, and to compare health-related quality of life (HRQOL) according to the type, and number of comorbidities. Methods: A total of 250 adults undergoing hemodialysis were recruited at local clinics. HRQOL was measured using the 12-item Medical Outcomes Study Short Form questionnaire. Data were analyzed using descriptive statistics, analysis of variance, and t test. Results: Around 70.8% of patients with end stage renal disease had 1 or more comorbidities, and the most common comorbidities were hypertension, diabetes, and cardiovascular disease. HRQOL was significantly different based on the number of comorbidities (F = 9.83, p < 0.001). The effect of comorbidities on the scores for mental health domains of the HRQOL questionnaire was not conclusive compared with the scores for the physical domain which were conclusive. Among the comorbidities, diabetes was associated with a lower quality of life. Conclusion: The customized management of diabetic and hypertensive patients is necessary for the early detection and prevention of chronic kidney disease, and slowing the progression of renal disease and managing cardiovascular risk factors is essential.

| ○ | ○ | Article | Hepatoprotective effects of gamma-aminobutyric acid-enriched fermented Hovenia dulcis extract on ethanol-induced liver injury in mice | Background: Various extracts of Hovenia dulcis have been commonly used in Asia for cases of alcohol-related disorders. Fermentation is reported to enhance the level and biological activities of various bio-constituents of plant extracts. Therefore, this study was undertaken to evaluate the effects of fermented H. dulcis extract (FHDE) on ethanol-induced liver injury in mice. Methods: FHDE was prepared using Bacillus subtilis and Lactobacillus plantarum. The effects of FHDE on ethanolinduced liver injury were evaluated in C57BL/6 N CrSlc mice. A mixed feed preparation containing the fermented extract with and without ethanol was given to mice for 29 days, according to its group. At the end of the experiment, blood and liver samples were collected from all mice in the group. Plasma biochemical analysis and histopathological investigation were performed to evaluate the impacts of treatment on the biomarkers of hepatic damage and inflammatory changes. Besides, the expression of genes that regulate the activities of enzymes associated with alcohol metabolism, antioxidant activity, and fatty acid oxidation was assessed using a quantitative real-time polymerase chain reaction. Moreover, the amino acid contents and the active ingredients of the extract were evaluated before and after fermentation. Results: Fermentation resulted in a marked increase and decrease in the amount of Gamma-Amino-n-butyric acid (GABA) and glutamic acid, respectively. FHDE enhanced the body weight gain of mice compared to ethanol. Besides, plasma levels of triglyceride, low-density lipoprotein, the activities of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly (P < 0.05) reduced in the FHDE-treated groups relative to the ethanol-treated control. FHDE upregulated the expression of genes associated with enzymes involved in alcohol dehydrogenation (Adh1 and Aldh2), antioxidant activity (SOD and CAT), and fatty acid oxidation (PPAR-alpha and PGC-1 alpha). However, the expressions of Cytochrome peroxidase Cyp(2)E(1) and genes related to lipogenesis (SREBP-1c, FAS, SCD-1, and ACC) were significantly (P < 0.05) downregulated following treatment with the FHDE. Histopathological investigation demonstrated a slight degree of inflammatory cell infiltration and occasional fatty changes in the FHDE-treated groups. Conclusion: The GABA-enriched fermented H. dulcis extract prevented ethanol-induced hepatic damage by enhancing the antioxidant defense system, fatty acid oxidation, and reducing lipogenesis. | Park, Na-Hye; Lee, Seung-Jin; Mechesso, Abraham Fikru; Boby, Naila; Quah Yixian; Yoon, Woong-Kyu; Lee, Sam-Pin; Lee, Jong-Suk; Park, Seung-Chun | Kyungpook Natl Univ, Coll Vet Med, 80 Daehak Ro, Daegu 41566, South Korea; Keimyung Univ, Dept Food Sci & Technol, Daegu 42601, South Korea; Gyeonggido Business & Sci Accelerator GBSA, Bioctr, Suwon 16229, Gyeonggi Do, South Korea | Lee, Jae/J-5597-2012; Park, Seung-Chun/AAV-3388-2021; Mechesso, Abraham/AAU-7158-2021; Lee, Jun Young/CAI-2335-2022; Boby, Naila/GRE-8096-2022; Yixian, Quah/ABE-7629-2021 | 57192425603; 58689440900; 56811692500; 57197787296; 55886933200; 57204053204; 57216647188; 58375930800; 7501832396 | parksch@knu.ac.kr; | BMC COMPLEMENTARY MEDICINE AND THERAPIES | BMC COMPLEMENT MED | 2662-7671 | 20 | 1 | SCIE | INTEGRATIVE & COMPLEMENTARY MEDICINE | 2020 | N/A | 1.27 | 2025-06-25 | 13 | 16 | Ethanol; Fermentation; Hepatoprotective; Hovenia dulcis; gamma-Aminobutyric acid; Lipogenesis | ACTIVATED PROTEIN-KINASE; INTESTINAL MICROBIOME; INDUCED STEATOSIS; IN-VITRO; ALCOHOL; HEPATOTOXICITY; SUPPRESSION; EXPRESSION; MECHANISM; PATHWAY | Ethanol; Fermentation; Hepatoprotective; Hovenia dulcis; Lipogenesis; γ-Aminobutyric acid | Animals; Chemical and Drug Induced Liver Injury; Chromatography; Disease Models, Animal; Ethanol; Fermentation; gamma-Aminobutyric Acid; Lipogenesis; Mass Spectrometry; Mice; Mice, Inbred C57BL; Oxidative Stress; Plant Extracts; Republic of Korea; Rhamnaceae; 4 aminobutyric acid; alcohol; plant extract; animal; C57BL mouse; chemistry; chromatography; disease model; drug effect; fermentation; lipogenesis; mass spectrometry; mouse; oxidative stress; Rhamnaceae; South Korea; toxic hepatitis | English | 2020 | 2020-03-06 | 10.1186/s12906-020-2866-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Proceedings Paper | Hierarchical Optimization of Speed and Gearshift Control for Battery Electric Vehicles Using Preview Information | This paper addresses the hierarchical optimization of speed and gearshift control for battery electric vehicles using short-range traffic information. To achieve greater electric motor efficiency, a multi-speed transmission is employed, whose control involves discrete-valued gearshift signals. To overcome the computational difficulties in solving the integrated speedand-gear-shift optimal control problem that involves both continuous and discrete-valued optimization variables, we propose a hierarchical procedure to decompose the integrated hybrid problem into purely continuous and discrete sub-problems, each of which can be efficiently solved. We show, by simulations in various driving scenarios, that the hierarchical optimization of speed and gearshift control can achieve greater energy efficiency than other typical approaches. | Han, Kyoungseok; Li, Nan; Kolmanovsky, Ilya; Girard, Anouck; Wang, Yan; Filev, Dimitar; Dai, Edward | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Univ Michigan, Dept Aerosp Engn, Ann Arbor, MI 48109 USA; Ford Motor Co, Dearborn, MI 48124 USA | Li, Nan/Q-5511-2019 | 56465294700; 57193099518; 7006937254; 7102803626; 56288919000; 7004005522; 55811712900 | kyoungsh@knu.ac.kr;nanli@umich.edu;ilya@umich.edu;anouck@umich.edu;ywang21@ford.com;dfilev@ford.com;zdai@ford.com; | 2020 AMERICAN CONTROL CONFERENCE (ACC) | 0743-1619 | 2378-5861 | 2.75 | 2025-06-25 | 11 | 12 | OPTIMAL ENERGY MANAGEMENT; COMMAND | Automotive batteries; Battery electric vehicles; Energy efficiency; Information use; Optimal control systems; Speed; Electric motor efficiency; Gearshift control; Hierarchical optimization; Multi-speed transmissions; Optimal control problem; Optimization variables; Sub-problems; Traffic information; Street traffic control | English | 2020 | 2020 | 10.23919/acc45564.2020.9147841 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | High efficiency drive strategy of dual three-phase permanent magnet synchronous motor | The dual three-phase permanent magnet synchronous motor drive system consist of dual three-phase inverter and dual three-phase stator winding set in motor. The dual drive-mode that utilizes dual stator winding set and dual three-phase inverter is commonly used for general operation. However, in order to improve the total efficiency of the drive system, it is also necessary to consider the efficiency of a single drive mode such as a conventional three-phase drive. In this paper, the high efficiency drive strategy of dual three-phase permanent magnet synchronous motor is proposed to utilize the highest efficiency point in each drive mode. Based on the analysis about efficiency for each drive-mode, the drive-mode changeover is proposed. The experimental results validate the proposed high efficiency drive strategy. © 2020 Korean Institute of Electrical Engineers.

| ○ | ○ | Proceedings Paper | High-resolution binary hologram printing methods | Recently the technology of hologram receives a lot of interest owing to its advantages and many researches on hologram recordings have been actively studied. In some studies, digital hologram printing methods have lots of applications because of the ability to record large area hologram based on the technique of holographic stereogram. The holographic stereogram printing method records the hologram composed of hogels which are the unit of the hologram recorded at once. This method has advantages in flexibility of the size since it records the hologram hogel by hogel. In addition, the hologram printer records not only wavefront of real objects captured by charge coupled device (CCD) but also hologram patterns of virtual objects calculated by computer-generated hologram (CGH) algorithm. In previous systems, it is difficult to implement the hologram in high resolution because of the low numerical aperture of hogels. In this paper, we suggest the method of recording high-resolution hologram using binary wavefront pattern and discuss the optical modulation properties of the printed binary pattern. | Jeon, Hosung; Kim, Beomjun; Jun, Minwoo; Kim, Hwi; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Korea Univ, Dept Elect & Informat Engn, 2511 Sejong Ro, Sejong 30019, South Korea | 56663784700; 57216150371; 57216163492; 8933596300; 10142501600 | jhahn@knu.ac.kr; | PRACTICAL HOLOGRAPHY XXXIV: DISPLAYS, MATERIALS, AND APPLICATIONS | 0277-786X | 1996-756X | 11306 | 0.78 | 2025-06-25 | 2 | 2 | Digital holography; Hologram printer; Binary Hologram; Depth map CGH | Binary Hologram; Depth map CGH; Digital holography; Hologram printer | Charge coupled devices; Computer generated holography; Electron holography; Holographic displays; Lithography; Optical properties; Printers (computer); Printing presses; Wavefronts; Binary holograms; Computer generated holograms; Depth Map; Digital holograms; Digital holography; Hologram recording; Modulation properties; Numerical aperture; Holograms | English | 2020 | 2020 | 10.1117/12.2545525 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | HILBERT BASIS THEOREM FOR RINGS WITH *-NOETHERIAN SPECTRUM | Let R be a commutative ring with identity, R[X] the polynomial ring over R, (*) a radical operation on R and (*) a radical operation of finite character on R[X]. In this paper, we give Hilbert basis theorem for rings with (*)-Noetherian spectrum. More precisely, we show that if (I* R[X])* = (IR[X])* and (I* R[X])* boolean AND R = I* for all ideals I of R, then R has (*)-Noetherian spectrum if and only if R[X] has *-Noetherian spectrum. This is a generalization of a well-known fact that R has Noetherian spectrum if and only if R[X] has Noetherian spectrum. | Park, Min Ji; Lim, Jung Wook | Hannam Univ, Coll Life Sci & Nano Technol, Dept Math, Daejeon 34430, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea | 57221553887; 35766755400 | mjpark5764@gmail.com;jwlim@knu.ac.kr; | JOURNAL OF APPLIED MATHEMATICS & INFORMATICS | J APPL MATH INFORM | 2734-1194 | 2234-8417 | 38 | 3-4 | ESCI | MATHEMATICS, APPLIED | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | (*)-Noetherian spectrum; (*)-finite ideal; radical operation; finite character | *-finite ideal; *-Noetherian spectrum; Finite character; Radical operation | English | 2020 | 2020 | 10.14317/jami.2020.271 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Horizontally grown tin-doped indium-oxide nanowires | Controlling the growth of nanowires and assembling them on planar substrates is of enormous importance for nanoscale device applications using the bottom-up approach. The tin-doped indiumoxide (ITO) nanowires were grown via direct thermal-chemical vapor deposition without the use of a pre-deposited catalyst. Growth was initiated by the formation of a Sn droplet that acted as a catalyst for ITO nanowire growth. With increasing growth time, the ITO nanowires grew horizontally in the early stages and then showed a horizontal-to-vertical growth mode transition. By reducing the rate of growth, we were able to obtain horizontally grown ITO nanowires without vertically grown ones. This is due to the horizontal growth period being increased by extending the transition time to vertical growth by reducing the growth rate. These results not only give important implications for the horizontal growth of other nanowires, but also point to potential applications in nanowire devices. © 2020 The Korean Physical Society.

| ○ | Book chapter | How it works: Major mechanism of antibacterial agents | Antibacterial agent is a natural or synthetic compound which inhibits the growth of bacteria in microorganisms. These agents determine their antibacterial range according to the type of targeted bacteria and are commonly divided into gram-positive bacteria and gram-negative bacteria. If agents act on both gram-positive and -negative bacteria, it can be classified as a broad-spectrum antibacterial agent. Moreover, if only a few of them work on it, they can be classified as a medium-spectrum antibacterial agent. In general, antibacterial agents are categorized based on structural features and mode of action. These include five main topics: inhibition of cell wall synthesis, disturbance of nucleic acid synthesis, protein synthesis, folic acid and cell membrane dysfunction by changing cell membrane permeability. This chapter focused on characteristicmechanism of five main categories and the corresponding representative type of antibacterial agents. © 2020 by Nova Science Publishers, Inc. | Kim, Hee Su; Lee, Dong Gun | School of Life Sciences, College of Natural Sciences, Kyungpook National University, Daegu, South Korea; School of Life Sciences, College of Natural Sciences, Kyungpook National University, Daegu, South Korea | 57219859173; 55668060900 | dglee222@knu.ac.kr; | An Introduction to Antibacterial Properties | 0 | 2025-06-25 | 0 | Antibacterial agent; Cell membrane dysfunction; Gram-negative bacteria; Gram-positive bacteria | English | Final | 2020 | 바로가기 | |||||||||||||||||||||
| ○ | Article | How to use energy device for pure laparoscopic donor hepatectomy | Background: Donor safety in living donor hepatectomy is the most important problem in living donor liver transplantation (LDLT). However, pure laparoscopic approach to donor hepatectomy has been gradually increased with experience of laparoscopic liver resection (LLR) and LDLT. Blood loss is one of the main causes that affect surgical outcomes in LLR and must be considered a major concern for the donor surgeon in LDLT. Methods: We would like to describe a few center’s experience with our clinical applications about how to use energy devices in pure laparoscopic donor hepatectomy (PLDH). Results: Various energy devices used for liver dissection play an important role in reducing intra-operative blood loss during LLR. And, energy devices make it easier to dissect perihepatic ligaments and retrohepatic space for liver mobilization. The optimal combination and selection of energy devices will help to reduce operation time and intra-operative complications during PLDH. Especially, meticulous dissection by the proper use of energy devices is essential to preserve the major vascular branches along the resection plane and to minimize the bleeding risk, during parenchymal transection in PLDH. Conclusions: The technology of energy devices should be continuously improved to accomplish the safe PLDH, and the surgical techniques associated with energy devices must be consistently validated. © Laparoscopic Surgery.

| ○ | Proceedings Paper | Human Activity Prediction-aware Sensor Cycling in Smart Home Networks | Activity recognition in smart homes required extensive machine learning methods operating over data obtained from the sensors connected to various things at homes. However, human behavior is always dynamic and there is a possibility of missing important activities. Similarly, the sensors operate over battery power, and detecting frequent activities can drain the battery eventually. In this paper, we propose Human Activity Predication-aware Sensor Cycling (HAPSC) approach that efficiently detects the future activities and designates the sensors to each predicated activity using a hybrid Long-Short Term Memory (LSTM) model with the Quality Learning (QL) support. The QL is added to detect those activities which are missed during the training process. The simulation is performed in comparison with the leading machine learning algorithms for the detection accuracy and energy consumption of the sensors. The performance evaluation shows that the proposed scheme detects the activities with an accuracy of 85.7% to 99.4%. Similarly, the energy consumption of the sensors and the network lifetime is significantly improved compared to existing duty cycling schemes. | Khan, Murad; Saad, Malik Muhammad; Tariq, Muhammad Ashar; Seo, Junho; Kim, Dongkyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | ; Khan, Turyalai/HPH-0061-2023; Saad, Malik/ABF-9433-2021 | mkhan@knu.ac.kr;maliksaad84@gmail.com;tariqashar@knu.ac.kr;junhoseo@knu.ac.kr;dongkyun@knu.ac.kr; | 2020 IEEE GLOBECOM WORKSHOPS (GC WKSHPS) | 2166-0069 | 3 | Smart homes; sensor duty cycling; machine learning; activity predications | English | 2020 | 2020 | 10.1109/gcwkshp50303.2020.9367449 | 바로가기 | 바로가기 | ||||||||||||||||||||
| ○ | Article | Human parechovirus: An emerging cause of sepsis-like syndrome in infants aged under 3 months | Purpose: This study aimed to investigate the clinical characteristics of human parechovirus (HPeV) infection in sepsis-like syndrome in infants aged under 3 months. Methods: Medical records of infants aged under 3 months with sepsis-like symptoms who were admitted between July 1, 2018 and August 31, 2018 were reviewed. A multiplex reverse transcription-polymerase chain reaction panel test was performed on the cerebrospinal fluid (CSF). Thirty-nine enrolled infants were categorized into three groups: 11 in group 1 (HPeV detected in the CSF), 13 in group 2 (enterovirus detected in the CSF), and 15 in group 3 (no virus detected in the CSF). Results: Compared with groups 2 and 3, a higher proportion of group 1 had tachycardia, tachypnea, apnea, and hypotension (P<0.05). A significantly lower white blood cell (WBC) count was noted in group 1 than in groups 2 and 3 (5,622±2,355/μL, 9,397±2,282/μL, and 12,312±7,452/μL, respectively; P=0.005). The CSF WBC count was lower in group 1 than in groups 2 and 3 (0.9±1.7/μL, 85.1±163.6/μL, and 3.7±6.9/μL, respectively; P=0.068). The proportion of patients requiring inotrope support (36.6% vs. 0% and 6.6%), mechanical ventilation (18.1% vs. 0% and 0%), and high flow nasal cannula (45.4% vs. 15.3% and 6.6%) was higher in group 1 than in groups 2 and 3. All patients recovered completely without complications. Conclusions: HPeV infection shows a severe clinical course and can cause a severe sepsis-like syndrome in infants aged under 3 months. Early diagnosis and proper treatment of HPeV infection are required. © 2020 The Korean Society of Pediatric Infectious Diseases. | Roh, Da Eun; Kwon, Jung Eun; Kim, Yeo Hyang | Department of Pediatrics, School of Medicine, Kyungpook National University, Kyungpook National University Children's Hospital, Daegu, South Korea; Department of Pediatrics, School of Medicine, Kyungpook National University, Kyungpook National University Children's Hospital, Daegu, South Korea; Department of Pediatrics, School of Medicine, Kyungpook National University, Kyungpook National University Children's Hospital, Daegu, South Korea | 57195734230; 57194002366; 57032023800 | kimyhmd@knu.ac.kr; | Pediatric Infection and Vaccine | 2384-1079 | 27 | 2 | 0.1 | 2025-06-25 | 1 | Fever; Infant; Parechovirus; Sepsis; Systemic inflammatory response syndrome | alanine aminotransferase; aspartate aminotransferase; C reactive protein; procalcitonin; apnea; Article; artificial ventilation; breathing rate; cerebrospinal fluid analysis; Cryptococcus gattii; Cryptococcus neoformans; Cytomegalovirus; disease course; disease severity; electrolyte blood level; endotracheal intubation; erythrocyte sedimentation rate; Escherichia coli; fever; Haemophilus influenzae; Herpes simplex virus 2; high flow nasal cannula therapy; hospital admission; hospital discharge; hospitalization; human; Human alphaherpesvirus 1; Human herpesvirus 6; Human parechovirus; hypotension; infant; intensive care unit; leukocyte count; Listeria; major clinical study; meningitis; multiplex reverse transcription polymerase chain reaction; parechovirus infection; potassium blood level; prognosis; sepsis; sodium blood level; Streptococcus agalactiae; Streptococcus pneumoniae; tachycardia; tachypnea; Varicella zoster virus; virus detection | English | Final | 2020 | 10.14776/piv.2020.27.e12 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Proceedings Paper | HW/SW Co-Design of Cost-Efficient CNN Inference for Cognitive IoT | Cognitive Internet of things (IoT) is a novel paradigm that outfits the contemporary IoT with a "brain" to impart high-level intelligence. Convolutional neural networks (CNNs) are an integral part of cognitive IoT that support inference and decision-making. In this paper, we demonstrate a resource-efficient hardware/software (HW/SW) co-design of a CNN architecture for cognitive IoT. We only offload image-to-column (im2col) and general matrix multiply (GEMM), which are the most time- and energy-consuming part of convolution layer operations, to the field-programmable gate array (FPGA)-based accelerator. We also exploit the parallelism in the operations of convolution layers to efficiently hide a non-negligible portion of execution time required for bias and activation. Experimental results demonstrate the resource, performance, and energy efficiency of our HW/SW co-design. Results indicate a speedup of 1.3X similar to 2.0X and energy reduction of 19.4%similar to 44.3% as compared to using only a general-purpose processor. | Lee, Kwangho; Kong, Joonho; Munir, Arslan | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea; Kansas State Univ, Dept Comp Sci, Manhattan, KS USA | 57194534319; 25927220400; 24587067400 | Ikh@knu.ac.kr;joonho.kong@knu.ac.kr;amunir@ksu.edu; | 2020 FOURTH INTERNATIONAL CONFERENCE ON INTELLIGENT COMPUTING IN DATA SCIENCES (ICDS) | 1.09 | 2025-06-25 | 0 | 7 | Convolutional neural networks; cognitive engine; Internet of things; hardware/software co-design; cost efficiency | cognitive engine; Convolutional neural networks; cost efficiency; hardware/software co-design; Internet of things | Convolution; Convolutional neural networks; Data Science; Decision making; Energy efficiency; Field programmable gate arrays (FPGA); General purpose computers; Hardware-software codesign; Integrated circuit design; Intelligent computing; Cognitive internets; Cost-efficient; Energy reduction; Energy-consuming parts; General purpose processors; HW/SW Codesign; Matrix multiply; Resource-efficient; Internet of things | English | 2020 | 2020 | 10.1109/icds50568.2020.9268757 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Review | Hypertension and electrolyte disorders in patients with COVID-19 | The worldwide coronavirus disease 2019 (COVID-19) pandemic is still in progress, but much remains unknown about the disease. In this article, we review the association of hypertension or the renin-angiotensin system (RAS) with COVID-19 and the correlation between electrolyte disorders and disease severity. Underlying hypertension is likely to be associated with severe or critical COVID-19, but the relationship is not clear owing to confounding factors. Angiotensin-converting enzyme 2 (ACE2) plays an important role in the non-classical RAS pathway and binds to a receptor binding domain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The RAS blockade is known to increase ACE2 levels, but controversy remains regarding the effect of RAS blockade therapy in the course of COVID-19. Some reports have indicated a protective effect of RAS blockade on COVID-19, whereas others have reported an association of RAS blockade therapy with the occurrence of severe complications such as acute kidney injury and admission to the intensive care unit. Electrolyte disorders are not uncommon in patients with COVID-19, and severe COVID-19 has frequently shown hypokalemia, hyponatremia, and hypocalcemia. Electrolyte imbalances are caused by alteration of RAS, gastrointestinal loss, effects of proinflammatory cytokines, and renal tubular dysfunction by the invasion of SARS-CoV-2.
