| ○ | ○ | Article | Health-Related Quality of Life According to Sociodemographic Characteristics in the South Korean Population | Health-related quality of life (HRQoL) concerns satisfaction with life and happiness with regard to physical, mental, and social factors. RAND-36 is a publicly available, self-administered questionnaire that examines eight health dimensions. This study evaluated the HRQoL of the South Korean population using the RAND-36 questionnaire and compared HRQoL across sociodemographic characteristics. From May 2015 to May 2019, South Koreans who visited public places aged 19-80 years were recruited and the RAND-36 questionnaire was administered. Overall, 1002 participants were recruited (mean age 45.34 years, 52% men). Men scored better than women in both physical and mental health (p < 0.05). There were significant differences in bodily pain (p < 0.05), general health perception (p < 0.05), and energy/fatigue (p < 0.05) dimensions according to the participants' health condition. The HRQoL of South Koreans was lower than average in most dimensions compared with other countries. As the first study to assess this, its data can be used in future studies that apply RAND-36 to evaluate the HRQoL of diseased individuals, as they can compare their findings with those of our study population. | Park, Chan-Hee; Park, Eunhee; Oh, Hyun-Min; Lee, Su-Jin; Park, Sun-Hee; Jung, Tae-Du | Kyungpook Natl Univ Hosp, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Rehabil Med, Chilgok Hosp, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Nephrol, Daegu 41944, South Korea | 57299095700; 56107216400; 57200994449; 57207933350; 7501831741; 36622364500 | chany9090@gmail.com;ehmdpark@knu.ac.kr;ohm0105@gmail.com;sujin89898@gmail.com;00sum@hanmail.net;teeed0522@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 9 | 0.09 | 2025-06-25 | 1 | 1 | health-related quality of life; RAND-36; South Korea | SF-36 | health-related quality of life; RAND-36; South Korea | Asians; Female; Humans; Male; Mental Health; Middle Aged; Quality of Life; Republic of Korea; Surveys and Questionnaires; South Korea; demography; life satisfaction; mental health; quality of life; adult; aged; Article; bodily pain; clinical assessment tool; controlled study; Cronbach alpha coefficient; cross-sectional study; demography; emotional disorder; energy; fatigue; female; general health perception; health; human; major clinical study; male; mental health; middle aged; pain; perception; physical disability; quality of life; questionnaire; RAND 36 questionnaire; reliability; retrospective study; scoring system; sex difference; social status; socioeconomics; South Korea; statistical significance; Asian; mental health; psychology; questionnaire | English | 2022 | 2022-05 | 10.3390/ijerph19095223 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Healthcare Workforce Response to The Coronavirus Disease Outbreak in Daegu, Korea: A Multi-Center, Cross-Sectional Survey | Background: Securing an available healthcare workforce is critical to respond to coronavirus disease 2019 (COVID-19); however, research investigating Korea's COVID-19 staffing response is rare. To present the fundamental data of healthcare staff in response to the surge in COVID-19 cases, we investigated the healthcare workforce response in Daegu, South Korea, which experienced the first largest outbreak of COVID-19 outside of China. Materials and Methods: In response to the COVID-19 outbreak, this retrospective cross-sectional study analyzed data on the scale and characteristics of healthcare workers (HCWs). Additionally, it analyzed the clinical and epidemiological characteristics of HCWs infected with COVID-19 in six major teaching hospitals (five tertiary and one secondary) in Daegu from January 19 to April 30, 2020. Results: During this study period, only 1.3% (n = 611) of the total hospitalized patients (n = 48,807) were COVID-19 inpatients, but they occupied 6.0% (n = 303) of the total hospital beds (n = 5,056), and 23.7% (n = 3,471) of all HCWs (n = 14,651) worked in response to COVID-19. HCWs participating in COVID-19-related works comprised 50.6% (n = 1,203) of doctors (n = 2,379), 26.3% (n = 1,571) of nurses (n = 5,982), and 11.4% (n = 697) of other HCWs (n = 6,108). Only 0.3% (n = 51) of HCWs (n = 14,651) developed COVID-19 infections from community-acquired (66.7%) or hospital-acquired (29.4%). Nurses were affected predominantly (33.3%), followed by doctors (9.8%), caregivers (7.8%), radiographers (5.9%), and others (45.1%), including nurse aides and administrative, facility maintenance, telephone appointment centers, and convenience store staff. All HCWs infected with COVID-19 recovered completely. The 32.7% (n = 333) of individuals (n = 1,018) exposed to HCWs who had COVID-19 were quarantined, and only one case of secondary transmission among them occurred. Conclusion: The COVID-19 pandemic has necessitated significant staffing and facility usage, which is disproportionate to the relatively low number of COVID-19 inpatients, imposing a substantial burden on healthcare resources. Therefore, beyond the current reimbursement level of the Korean National Health Insurance, a new type of rewarding system is needed to prepare hospitals for the emerging outbreaks of infectious diseases. Keeping HCWs safe from COVID-19 is crucial for maintaining the healthcare workforce during a sudden massive outbreak. Further studies are needed to determine the standards of required HCWs through detailed research on the working hours and intensity of HCWs responding to COVID-19. | Kwon, Hyun Hee; Kim, Hye In; Kwon, Ki Tae; Hwang, Soyoon; Kim, Shin-Woo; Kim, Yoonjung; Kim, Hyun Ah; Hyun, Miri; Hong, Hyo-Lim; Kim, Min Jung; Hur, Jian; Hong, Kyung Soo | Catholic Univ Daegu, Sch Med, Dept Internal Med, Daegu, South Korea; Daegu Fatima Hosp, Dept Infect Dis, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Internal Med, Div Infect Dis, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Div Infect Dis,Dept Internal Med, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Infect Dis, Daegu, South Korea; Daegu Vet Hosp, Dept Internal Med, Daegu, South Korea; Yeungnam Univ, Med Ctr, Dept Internal Med, Daegu, South Korea | ; Kim, Seung/N-5248-2019; Hwang, Soyoon/HHM-5762-2022; Kim, Hanjin/KYP-2633-2024; Kim, Jin Young/AAB-6510-2020; Kim, Jihyun/F-6940-2013; Kim, Sooyeon/AAA-8521-2022 | 16301508200; 57208153832; 9733850500; 57203160675; 57189703358; 57203160508; 57059615500; 55927698200; 55440169300; 57208371904; 19934047300; 56645558700 | hyunah1118@dsmc.or.kr;ktkwon@knu.ac.kr; | INFECTION AND CHEMOTHERAPY | INFECT CHEMOTHER | 2093-2340 | 2092-6448 | 54 | 2 | ESCI | INFECTIOUS DISEASES | 2022 | 4.2 | 0.8 | 2025-06-25 | 6 | 6 | SARS-CoV-2; Health personnel; Infection control; Personal protective equipment; Health facilities | Health facilities; Health personnel; Infection control; Personal protective equipment; SARS-CoV-2 | administrative personnel; adult; Article; caregiver; clinical feature; coronavirus disease 2019; cross-sectional study; epidemic; female; health care personnel; health care survey; health workforce; hospital patient; human; infection control; major clinical study; male; nurse; nursing assistant; physician; radiographer; retrospective study; secondary care center; South Korea; tertiary care center | English | 2022 | 2022-06 | 10.3947/ic.2022.0031 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Hematology, Serum Biochemistry, and Acute Phase Proteins in Hanwoo (Bos taurus coreanae) Calves with Diarrhea | This study was conducted to identify the useful blood variables in di-agnosing calf diarrhea in Hanwoo calves and good indicators for calf diarrhea. In 530 Hanwoo calves, fecal scores were recorded on a scale of 0 to 3, and blood samples were collected and analyzed for hematology, serum biochemistry, and acute phase proteins. Among the blood variables, 16 blood variables showed significant differences (p < 0.01) according to fecal scores. After reference intervals of these 16 blood variables were calculated, the distributions of calves by calculated reference intervals showed a significant difference (p < 0.001) and lin-ear associations (p < 0.001) in blood urea nitrogen (BUN), glucose (GLU), blood sodium concentration (Na), blood potassium concentration (K), fibrinogen (Fib), and haptoglobin (Hp). Of 6 blood variables, the optimal cut-off values were calculated for BUN, K, Fib, and Hp, and the area under the curve was 0.5 or more: BUN (9.5 mg/dL, AUC: 0.623), K (5.8 mmol/L, AUC: 0.599), Fib (650.0 mg/dL, AUC: 0.706), and Hp (12.5 mg/dL, AUC: 0.847). These findings could be useful in evaluating calves with diarrhea and making decision of further treatment of calf diarrhea in Hanwoo calves. © The Korean Society of Veterinary Clinics. | Chae, Jeong-Byoung; Ku, Ji-Yeong; Park, Kwang-Man; Choi, Kyoung-Seong; Chae, Joon-Seok; Park, Jinho | Laboratory of Veterinary Internal Medicine, BK21 PLUS Program for Creative Veterinary Science Research, Research Institute for Veterinary Science and College of Veterinary Medicine, Seoul National University, Seoul, 08826, South Korea; Department of Veterinary Internal Medicine, College of Veterinary Medicine, Jeonbuk National University, Iksan, 54596, South Korea; Department of Veterinary Internal Medicine, College of Veterinary Medicine, Jeonbuk National University, Iksan, 54596, South Korea; Department of Animal Science and Biotechnology, College of Ecology and Environmental Science, Kyungpook National University, Sangju, 37224, South Korea; Laboratory of Veterinary Internal Medicine, BK21 PLUS Program for Creative Veterinary Science Research, Research Institute for Veterinary Science and College of Veterinary Medicine, Seoul National University, Seoul, 08826, South Korea; Department of Veterinary Internal Medicine, College of Veterinary Medicine, Jeonbuk National University, Iksan, 54596, South Korea | 57037983200; 57753895700; 57219435315; 7403949556; 7102478039; 8730126700 | jpark@jbnu.ac.kr; | Journal of Veterinary Clinics | 1598-298X | 39 | 6 | 0.43 | 2025-06-25 | 2 | acute phase proteins; calf diarrhea; hanwoo calves; hematology; serum chemistry | acute phase protein; albumin; fibrinogen; glucose; haptoglobin; hemoglobin; potassium; serum amyloid A; sodium; animal cell; animal experiment; Article; basophil count; blood biochemistry; blood cell count; blood sampling; calf (bovine); controlled study; diagnostic accuracy; diagnostic test accuracy study; diarrhea; enzyme linked immunosorbent assay; eosinophil count; erythrocyte count; feces analysis; glucose blood level; hematocrit; hematology; leukocyte count; lymphocyte count; mean corpuscular hemoglobin; mean corpuscular hemoglobin concentration; mean corpuscular volume; monocyte count; neutrophil count; nonhuman; platelet count; potassium blood level; protein blood level; receiver operating characteristic; reticulocyte count; sensitivity and specificity; sodium blood level; urea nitrogen blood level; vaccination | English | Final | 2022 | 10.17555/jvc.2022.39.6.342 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | High School Students’ Preference for Physics and Interest in Learning Quantum Physics | As the importance of quantum technology is rising globally, it has become imperative to include quantum physics in the upcoming 2022 revised National Curriculum of Korea. To explore high school students’ perception on learning quantum physics, we surveyed their preference for physics and interest in learning quantum physics. We collected the student responses using an online survey and analyzed 931 responses overall. Notably, students showed a higher preference for quantum physics over other areas of physics in terms of the emotional response and valuational comprehension, while they showed a lower preference of quantum physics in behavioral volition. Students showed a higher interest in the study of atomic structure over quantum technology or quantum phenomena. They regarded the intellectual curiosity as a more important motive for interest than career relevancy and showed a high interest in experimental and cultural activities over others. The preference and interest of the students in learning quantum physics significantly differed with their grades and the future career paths. This study suggests the necessity to teach quantum physics in high schools as well as the implication for constructing a quantum physics curriculum. © 2022 The Korean Physical Society.

| ○ | Conference paper | High-Reliability Three-Phase Switching-Cells Current Source Inverter | The conventional three-phase current source inverter (CSI) suffers from the open-circuit problem. In CSI operation, the overlap-time in the gates signals needed for safe commutations causes the distortion in the output current waveforms. This paper proposes a new three-phase switching-cell current source inverter, called H6-SC-CSI. Based on switching-cells, the inverter reliability is enhanced because open-circuit concerns are eliminated, and the voltage over-shoot at turn-of is reduced. In the operation of the proposed CSI, switch overlap-time intervals can be minimized or eliminated. Therefore, the total harmonic distortion (THD) of the output current is reduced. A 1.2-kW prototype of the proposed inverter is designed and tested. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG. | Do, Hai Trung; Do, Duc-Tuan; Nguyen, Tien-The | Thai Nguyen University of Technology, Thai Nguyen, Viet Nam; Thai Nguyen University of Technology, Thai Nguyen, Viet Nam; Kyungpook National University, Daegu, 41566, South Korea | 37561306100; 57202470961; 59454647000 | doductuan-tdh@tnut.edu.vn; | Lecture Notes in Networks and Systems | 2367-3370 | 366 LNNS | 0 | 2025-06-25 | 0 | Current source inverter; Reliability; Switching-cell; Three-phase | English | Final | 2022 | 10.1007/978-3-030-92574-1_46 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Article | High-Throughput Root Imaging Analysis Reveals Wide Variation in Root Morphology of Wild Adzuki bean (Vigna angularis) Accessions | Root system architecture and morphological diversification in wild accessions are important for crop improvement and productivity in adzuki beans. In this study, via analysis using 2-dimensional (2D) root imaging and WinRHIZO Pro software, we described the root traits of 61 adzuki bean accessions in their early vegetative growth stage. These accessions were chosen for study because they are used in Korea's crop improvement programs; however, their root traits have not been sufficiently investigated. Analysis of variance revealed a significant difference between the accessions of all measured root traits. Distribution analysis demonstrated that most of the root traits followed normal distribution. The accessions showed up to a 17-fold increase in the values in contrasting accessions for the root traits. For total root length (TRL), the values ranged from 82.43 to 1435 cm, and for surface area (SA), they ranged from 12.30 to 208.39 cm(2). The values for average diameter (AD) ranged from 0.23 to 0.56 mm. Significant differences were observed for other traits. Overall, the results showed that the accession IT 305544 had the highest TRL, SA, and number of tips (NT), whereas IT 262477 and IT 262492 showed the lowest values for TRL, SA, and AD. Principal component analysis showed an 89% variance for PC1 and PC2. K-mean clustering explained 77.4% of the variance in the data and grouped the accessions into three clusters. All six root traits had greater coefficients of variation (>= 15%) among the tested accessions. Furthermore, to determine which root traits best distinguished different accessions, the correlation within our set of accessions provided trait-based ranking depending on their contribution. The identified accessions may be advantageous for the development of new crossing combinations to improve root features in adzuki beans during the early growth stage. The root traits assessed in this study could be attributes for future adzuki bean crop selection and improvement. | Tayade, Rupesh; Kim, Seong-Hoon; Tripathi, Pooja; Choi, Yi-Dam; Yoon, Jung-Beom; Kim, Yoon-Ha | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; RDA, Natl Inst Agr Sci, Natl Agrobiodivers Ctr, Jeonju 54874, South Korea; RDA, Natl Inst Hort & Herbal Sci, Hort & Herbal Crop Environm Div, Jeonju 54874, South Korea | ; Kim, Seong-Hoon/AHE-2059-2022; Tayade, Rupesh/AAM-9652-2021 | 57191753234; 57208236056; 57215084745; 57430855700; 55489819500; 57224866763 | rupesh.tayade@gmail.com;shkim0819@korea.kr;tripathipooza21@gmail.com;i_dont_care0@naver.com;beomi7944@korea.kr;kyh1229@knu.ac.kr; | PLANTS-BASEL | 2223-7747 | 11 | 3 | 1.46 | 2025-06-25 | 11 | 12 | cluster analysis; image analysis; legume; root architectural trait; root morphological trait | SYSTEM ARCHITECTURE; GENETIC-ANALYSIS; DROUGHT STRESS; TRAITS; WHEAT; GROWTH; YIELD; ASSOCIATION; IMPROVEMENT; EFFICIENCY | Cluster analysis; Image analysis; Legume; Root architectural trait; Root morphological trait | English | 2022 | 2022-02 | 10.3390/plants11030405 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | HIT HAR: Human Image Threshing Machine for Human Activity Recognition Using Deep Learning Models | In recent days, research in human activity recognition (HAR) has played a significant role in healthcare systems. The accurate activity classification results from the HAR enhance the performance of the healthcare system with broad applications. HAR results are useful in monitoring a person's health, and the system predicts abnormal activities based on user movements. The HAR system's abnormal activity predictions provide better healthcare monitoring and reduce users' health issues. The conventional HAR systems use wearable sensors, such as inertial measurement unit (IMU) and stretch sensors for activity recognition. These approaches show remarkable performances to the user's basic activities such as sitting, standing, and walking. However, when the user performs complex activities, such as running, jumping, and lying, the sensor-based HAR systems have a higher degree of misclassification results due to the reading errors from sensors. These sensor errors reduce the overall performance of the HAR system with the worst classification results. Similarly, radiofrequency or vision-based HAR systems are not free from classification errors when used in real time. In this paper, we address some of the existing challenges of HAR systems by proposing a human image threshing (HIT) machine-based HAR system that uses an image dataset from a smartphone camera for activity recognition. The HIT machine effectively uses a mask region-based convolutional neural network (R-CNN) for human body detection, a facial image threshing machine (FIT) for image cropping and resizing, and a deep learning model for activity classification. We demonstrated the effectiveness of our proposed HIT machine-based HAR system through extensive experiments and results. The proposed HIT machine achieved 98.53% accuracy when the ResNet architecture was used as its deep learning model. | Poulose, Alwin; Kim, Jung Hwan; Han, Dong Seog | Kyungpook Natl Univ, Ctr ICT & Automot Convergence, 80 Daehak ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Grad Sch Elect & Elect Engn, 80 Daehak ro, Daegu 41566, South Korea | POULOSE, ALWIN/S-4914-2018; Han, Dong Seog/N-8949-2018; , ALWIN POULOSE/S-4914-2018 | 57205504085; 57222321332; 7403219442 | alwinpoulosepalatty@knu.ac.kr;jkim267@knu.ac.kr;dshan@knu.ac.kr; | COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE | 1687-5265 | 1687-5273 | 2022 | 5.56 | 2025-06-25 | 26 | 37 | CONVOLUTIONAL NEURAL-NETWORKS; BEHAVIOR; SENSORS; SYSTEM | Deep Learning; Human Activities; Humans; Movement; Neural Networks, Computer; Smartphone; Agriculture; Convolutional neural networks; Errors; Health care; Learning systems; Pattern recognition; Real time systems; Wearable sensors; Activity classifications; Activity recognition; Broad application; Classification results; Healthcare systems; Human activity recognition; Human activity recognition systems; Learning models; Performance; Threshing machines; human; human activities; movement (physiology); smartphone; Deep learning | English | 2022 | 2022-10-06 | 10.1155/2022/1808990 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Proceedings Paper | Hold Voltage Behavior in NbOx Based Threshold Switches for Selector Technology and Neuromorphic Computing Applications | We study the insulator-metal transition characteristics of NbOx-based threshold switches to identify how the hold voltage (V-hold), which is a key knob for various applications, can be tuned towards low or high values. Since the hold behavior is rooted in threshold switching, we first investigate the electrical characteristics of the switches with respect to scaling of the NbOx film thickness and cell diameter. We then reveal that the hold properties are mainly related to the stability of the locally transformed metallic phase in the NbOx. Increasing the compliance current not only allows a geometrically thicker and denser phase to be formed, but also elevating the temperature makes the phase thermodynamically favorable, thereby lowering the V-hold. | Kim, Hyun Wook; Jin, Sol; Kang, Heebum; Hong, Eun Ryeong; Woo, Jiyong | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57557016000; 57796769200; 57232405900; 57556070800; 53985749100 | jiyong.woo@knu.ac.kr; | 6TH IEEE ELECTRON DEVICES TECHNOLOGY AND MANUFACTURING CONFERENCE (EDTM 2022) | 0.5 | 2025-06-25 | 0 | 1 | Threshold switching; NbOx; and hold behavior | hold behavior; NbO<sub>x</sub>; Threshold switching | Metal insulator transition; Semiconductor insulator boundaries; Computing applications; Electrical characteristic; Film-thickness; Hold behavior; Insulator metal transition; NbOx; Neuromorphic computing; Scalings; Threshold switches; Threshold switching; Niobium compounds | English | 2022 | 2022 | 10.1109/edtm53872.2022.9798045 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||

| ○ | Article | Homogenic Evaluation for Spatial Distribution in Osteoclast Differentiation | Background: Cells have heterogeneous cellular diversity in size, morphology, cell cycle, metabolism, differentiation degree, and spatial distribution. The shift of specific cells towards the desired cells is crucial for maintaining uniform cellular function and can be represented by homogeneity and heterogeneity. Here, we developed a simple and direct method for evaluating the homogeneous distribution of desired cells in a constant region. Methods: We differentiated osteoclast progenitors into bone-resorbing multinucleated giant osteoclasts in a 2-dimensional culture plate under 2 conditions. Cells were stained with tartrate-resistant acid phosphatase to assess osteoclast differentiation, images were taken using a microscope and divided into sectors, and the number of osteoclasts (≥3 nuclei) in each sector was counted. To assess the homogeneity of the spatial distribution of osteoclasts, the standard deviation (SD) was calculated from the mean number of osteoclasts within each sector. Results: From the 2 groups, a value with a SD close to 0 indicates high spatial homogeneity while a relatively high SD represents low spatial homogeneity. Conclusions: Our findings suggest that spatial homogeneity can be represented as SD.

| ○ | ○ | Article | How Was the World's Oldest Metal-Type-Printed Book (The Song of Enlightenment, Korea, 1239) Misidentified for Nearly 50 Years? | Six nearly identical versions of an ancient printed book, The Song of Enlightenment with Commentaries by Buddhist Monk Nammyeong Cheon, have been found in Korea since the 1920s. All of them were believed to be printed versions from the 13th to 16th centuries that used duplicated woodblocks of a metal-type-printed version from 1239 and its replica. Two of the six versions were designated as Korean treasures in 1984 and 2012. One other version was designated as a treasure of the Metropolitan city of Seoul, Korea in 2021. Since the 1970s, one of two Korean treasures has been identified as a potential movable metal-type-printed book prior to the Jikji printed in Korea in 1377, as recognized by the UNESCO Memory of the World program. The center of heated debates among Korean historians for the last 50 years was over the printing techniques and printing dates (or sequence). Due to the subjective nature of the examination, it was very difficult to reach a consensus. To end this heated debate, all six versions were examined by image comparisons of individual characters, lines of characters, pages and borderlines to identify whether they are the identical versions using the same woodblocks or different versions. Previous reports on the subjects were also reviewed very carefully. Very clear circumstantial and physical evidence showed that the one version designated as a Korean treasure in 2012 is significantly different from the others and was very likely printed using movable metal type in September 1239, as indicated in the imprint. It is the world's oldest extant book printed using metal type in 1239, 138 years prior to the printing date (1377) of Jikji. The mystery of the misidentification of the metal-printed book, as a woodblock print, has been revealed. | Yoo, Woo Sik | WaferMasters Inc, Dublin, CA 94568 USA; Kyungpook Natl Univ, Inst Humanities Studies, Daegu 41566, South Korea | 55665974300 | woosik.yoo@wafermasters.com; | HERITAGE | HERITAGE-BASEL | 2571-9408 | 5 | 3 | ESCI | HUMANITIES, MULTIDISCIPLINARY;MULTIDISCIPLINARY SCIENCES | 2022 | 1.7 | 2 | 2025-06-25 | 6 | 7 | The Song of Enlightenment; early history of printing; different printing versions; image comparison; printing technique; printing sequence; printing date | different printing versions; early history of printing; image comparison; printing date; printing sequence; printing technique; The Song of Enlightenment () | English | 2022 | 2022-09 | 10.3390/heritage5030092 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||
| ○ | ○ | Proceedings Paper | Human-Centric Autonomous Driving Based on a Two-Stage Machine Learning Algorithm | This paper presents a human-centric autonomous driving system, which is based on a two-stage machine learning algorithm. In particular, driving perception and human features are integrated to develop human-centric autonomous vehicles. Hence, we propose two-stage machine learning algorithms to identify the driver features such as age, location, sense, etc. We consider both online and offline learning to construct a two-stage distribution model and determine the relationship between the driver features and its cluster. The simulation results show the performance of the proposed two-stage learning algorithms in terms of a driver's feature training performance. | Sarker, Md Abdul Latif; Han, Dong Seog | Ctr ICT & Automot Convergence, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 42262729500; 7403219442 | latifsarker@knu.ac.kr;dshan@knu.ac.kr; | 2022 27TH ASIA PACIFIC CONFERENCE ON COMMUNICATIONS (APCC 2022): CREATING INNOVATIVE COMMUNICATION TECHNOLOGIES FOR POST-PANDEMIC ERA | 2163-0771 | 0.76 | 2025-06-25 | 2 | 2 | Human-centric; autonomous driving; machine learning; online and offline learning | autonomous driving; Human-centric; machine learning; online and offline learning | Clustering algorithms; E-learning; Intelligent vehicle highway systems; Learning algorithms; Machine learning; Autonomous driving; Autonomous Vehicles; Distribution models; Driving systems; Human-centric; Machine learning algorithms; Machine-learning; Off-line learning; Online learning; Performance; Autonomous vehicles | English | 2022 | 2022 | 10.1109/apcc55198.2022.9943704 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | Hydrogen Gas Sensor Performance of a p-CuO/n-ZnO Thin-film Heterojunction | Hydrogen (H2)gas is widely preferred for use as a renewable energy source owing to its characteristics such as environmental friendliness and a high energy density. However, H2can easily reverse or explode due to minor external factors. Therefore, H2gas monitoring is crucial, especially when the H2concentration is close to the lower explosive limit. In this study, metal oxide materials and their pn heterojunctions were synthesized by a hydrothermal-assisted dip-coating method. The synthesized thin films were used as sensing materials for H2gas. When the H2concentration was varied, all metal oxide materials exhibited different gas sensitivities. The performance of the metal oxide gas sensor was analyzed to identify parameters that could improve the performance, such as the choice of the metal oxide material, effect of the p-n heterojunctions, and operating temperature conditions of the gas sensor. The experimental results demonstrated that a CuO/ZnO gas sensor with a p-n heterojunction exhibited a high sensitivity and fast response time (134.9% and 8 s, respectively) to 5% H2gas at an operating temperature of 300oC. © 2022, Korean Sensors Society.

| ○ | Article | Iatrogenic pulmonary artery perforation associated with 5-Fr catheter manipulation during pulmonary arteriovenous malformation embolization with a vascular plug | Vascular plugs have been increasingly used because they have lower recanalization rates than coil embolization in pulmonary arteriovenous malformation (PAVM) embolization. To deliver the vascular plug close to the PAVM, a large-diameter catheter should be advanced into the feeding pulmonary artery, which carries a risk of vascular damage. Fifty-three-year-old women was admitted to our hospital for embolization of a single PAVM. Pulmonary angiography revealed a simple PAVM with a tortuous, small feeding artery in the right middle lobe, and feeding artery negotiation was attempted using a 5-Fr headhunter-type catheter to deliver the vascular plug. However, unintentional arterial perforation occurred suddenly when the guide wire was withdrawn after the catheter was advanced to the feeding artery adjacent to the sac. Immediate embolization using a vascular plug and microcoils at the proximal site of the perforation was performed to stop both PAVM shunt flow and bleeding. To prevent such a catheter-induced complication, it is necessary to select a diagnostic catheter with appropriate stiffness and angle and to switch to a small-diameter delivery system depending on the situation. © 2022 | Hong, Jihoon; Lee, Sang Yub; Cha, Jung Guen; Lee, Jaehee; Kim, Donghyeon | Department of Radiology, School of Medicine, Kyungpook National University, 130 Dongdeok-ro, Jung-gu, Daegu, South Korea; Department of Radiology, School of Medicine, Kyungpook National University, 130 Dongdeok-ro, Jung-gu, Daegu, South Korea; Department of Radiology, School of Medicine, Kyungpook National University, 130 Dongdeok-ro, Jung-gu, Daegu, South Korea; Department of Internal Medicine, School of Medicine, Kyungpook National University, 130 Dongdeok-ro, Junggu, Daegu, South Korea; Department of Radiology, Gyeongbuk Regional Rehabilitation Hospital, 120 Mirae-ro, Gyeongsan-si, Gyeongsangbuk-do, South Korea | 57215858314; 56016177400; 57206855971; 13805476000; 57387224200 | lsyrad@gmail.com; | Radiology Case Reports | 1930-0433 | 17 | 3 | 0 | 2025-06-25 | 0 | Hemothorax; Pulmonary arteriovenous malformation; Pulmonary artery perforation; Vascular plug | adult; arterial embolization; artery perforation; Article; artificial embolization; atelectasis; bleeding; case report; clinical article; computer assisted tomography; contrast medium extravasation; female; hematothorax; human; lung angiography; middle aged; pleura effusion; pulmonary arteriovenous fistula; pulmonary artery | English | Final | 2022 | 10.1016/j.radcr.2021.12.054 | 바로가기 | 바로가기 |
