| ○ | Article | Analysis of the Contents of Transistors in Physics II Textbooks of the 2015 Revised Curriculum | We analyzed the unit of transistors in all physics II textbooks of the 2015 revised curriculum to see if the contents are suitable for students to reach the standards suggested by the curriculum. Specifically, we investigated the description of the structure of a transistor, amplification in transistors, and transistor bias voltage in the textbooks in terms of description accuracy, the learner’s convenience, and illustration accuracy. We found that the explanation of the universal dc bias circuit is not enough that it is hard for students to choose a bias voltage using resistors in a transistor circuit as an amplifier. There is no description of the basic elements to understand how transistors work, such as the pn junction of semiconductors. In addition, it was found that there is a lack of explanation of the essential contents, and many inaccurate terms and vague illustrations. We discussed several implications of this study. © 2022 The Korean Physical Society.

| ○ | Article | Analysis of the Engine Load Factor for a 67 kW Agricultural Tractor | This study aims to analyze the engine load factor of a 67 kW agricultural tractor to calculate national emission. Engine power was calculated using engine CAN data measured by the load measurement system. Plow tillage, rotary tillage and driving (field and road) operations were selected as major agricultural operations, and the field test was conducted considering the gear stage and initial engine rotational speed as major variables. The engine load factor was calculated as the ratio of the engine power during operations and the engine rated power, and a weight factor according to the usage ratio (plow tillage: 35.1%, rotary tillage: 39.8%, driving operation: 25.1%) was applied. The engine load factor was 0.85, 0.93, and 0.32 on average in plow tillage, rotary tillage, and driving operations. The integrated engine load factor was calculated as 0.75. This was found to be about 1.56 times higher than the conventional engine load factor of 0.48. | Baek, Seung-Yun; Kim, Wan-Soo; Baek, Seung-Min; Jeon, Hyeon-Ho; Park, Su-Han; Kim, Jin-Sik; Yoo, Chul; Kim, Yong-Joo | Chungnam Natl Univ, Dept Smart Agr Syst, Daejeon, South Korea; Kyungpook Natl Univ, Dept Bio Ind Machinery, Daegu, South Korea; Konkuk Univ, Sch Mech & Aerosp Engn, Seoul, South Korea; Natl Air Emiss Inventory & Res Ctr, Emiss Inventory Management Team, Incheon, South Korea; Chungnam Natl Univ, Dept Biosyst Machinery Engn, Daejeon, South Korea | Kim, Yong-Joo/AAK-1840-2021 | babina@cnu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 46 | 3 | ESCI | ENGINEERING, MECHANICAL | 2022 | 0.3 | 1 | Agricultural Tractor; Engine Load Factor; Agricultural Operation; Load Measurement | Korean | 2022 | 2022-03 | 10.3795/ksme-a.2022.46.3.301 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | ○ | Proceedings Paper | Analysis of V2V Communication Performance on Roads and Tunnels Surrounded by Mountains | In this paper, communication performance analysis is conducted for driving scenario using IEEE 802.11p wireless access in vehicular environments (WAVE), a vehicle communication standard. Since vehicle communication is linked to advanced driver assistance systems such as safety and autonomous driving, it is very important to maintain stable communication performance. However, in the vehicle communication environment, it is difficult to ensure a stable performance because the communication terminal moves at high speed and there are various communication interference factors such as changes in the surrounding environment. Therefore, in this paper, scenarios are set for actual vehicle communication environments and the vehicle communication performance is analyzed for each situation based on actual measurement experiments. In the actual measurement experiment, the basic safety message (BSM) of the vehicle is transmitted and received in real-time using two vehicles with two WAVE devices. The received signal strength of the signal is analyzed while exchanging BSM messages. In this experiment, various scenarios are set up and the signal strength for each scenario is analyzed. This paper conducted a performance comparison using the received signal power of messages transmitted and received by driving conditions in the road environment by experimenting with vehicle-to-vehicle communication. | Yoon, Youngjin; Kim, Jihun; Han, Dong Seog | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57223310857; 56024681400; 7403219442 | skag2603@knu.ac.kr;soji0423@knu.ac.kr;dshan@knu.ac.kr; | 2022 THIRTEENTH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS (ICUFN) | 2165-8528 | 2165-8536 | 0.25 | 2025-06-25 | 0 | 1 | Autonomous driving system; Vehicle to everything (V2X) communication; Wireless access in vehicular environments (WAVE) | Autonomous driving system; Vehicle to everything (V2X) communication; Wireless access in vehicular environments (WAVE) | Advanced driver assistance systems; Automobile drivers; Autonomous vehicles; Vehicle performance; Vehicle to vehicle communications; Autonomous driving; Autonomous driving system; Communication environments; Communication performance; Driving systems; Vehicle communications; Vehicle to everything (V2X) communication; Vehicular environments; Wireless access; Wireless access in vehicular environment; Vehicle to Everything | English | 2022 | 2022 | 10.1109/icufn55119.2022.9829535 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Analysis on Seismic Observation Data through Operation of MEMS Acceleration Sensor Based CrowdQuake | CrowdQuake is a seismic observation network based on MEMS acceleration sensors. Starting with 300 smartphone-based seismic sensors in 2019, more than 5,200 sensors have been installed and operated nationwide in September 2021. In this paper, we analyze the seismic detection performance of CrowdQuake through two weeks of records in September 2021. First, we monitor changes in the number of sensors connected to the seismic network according to the time change. Then, we classify the recording quality of each sensor using K-means clustering. By classifying the data quality of a sensor, we can see how sensor data quality affects the overall performance of earthquake detection thereby analyzing the detection performance of CrowdQuake. In addition, to understand changes in data quality due to the weather, we collected sensor data when typhoon Omais was passed across the country in September 2021. Finally, we report two detected earthquake cases of magnitude 2.2 in Taean on September 17, 2021, and magnitude 2.2 in Boseong on September 20, 2021. © 2022, Korean Institute of Communications and Information Sciences.

| ○ | Conference paper | Analysis Result of the High-Energy Cosmic-Ray Proton Spectrum from the ISS-CREAM Experiment | The Cosmic Ray Energetics And Mass for the International Space Station (ISS-CREAM) experiment successfully recorded data for about 539 days from August 2017 to February 2019. In this talk, we report the measurement of the cosmic-ray proton energy spectrum from the ISS-CREAM experiment in the energy range of 2.5 TeV - 655 TeV. For the analysis, we used the silicon charge detector (SCD) placed at the top of the ISS-CREAM payload to identify the incoming cosmic-ray charge. The SCD is finely segmented to minimize charge misidentification due to backscatter effects. The four-layer SCD consists of 10,752 silicon pixels, each of which is 1.37 × 1.57 × 0.05 cm 3 in size. The calorimeter (CAL) consists of 20 layers of tungsten/scintillating fibers preceded by carbon targets. It provided cosmic-ray tracking, energy determination, and the high-energy trigger. The Top and Bottom Counting detectors (T/BCD) are above and below the CAL respectively and provided the low energy trigger. Each T/BCD is composed of an array of 20 × 20 photodiodes on plastic scintillators. The measured proton spectral index of 2.67 ±0.02 between 2.5 and 12.5 TeV is consistent with prior CREAM measurements. The spectrum softening above ∼ 10 TeV is consistent with the bump-like structure as reported by CREAM-I+III, DAMPE, and NUCLEON, but ISS-CREAM extends measurements to higher energies than those prior measurements. © Copyright owned by the author(s). | Choi, G.H.; Aggarwal, S.; Amare, Y.; Angelaszek, D.; Bowman, D.; Chen, Y.C.; Copley, M.; Derome, L.; Eraud, L.; Falana, C.; Gerrety, A.; Han, J.H.; Huh, H.G.; Haque, A.; Hwang, Y.S.; Hyun, H.J.; Jeon, H.B.; Jeon, J.A.; Jeong, S.; Kang, S.C.; Kim, H.J.; Kim, K.C.; Kim, M.H.; Lee, H.Y.; Lee, J.; Lee, M.H.; Lu, L.; Lundquist, J.P.; Lutz, L.; Menchaca-Rocha, A.; Ofoha, O.; Park, H.; Park, I.H.; Park, J.M.; Picot-Clemente, N.; Scrandis, R.; Seo, E.S.; Smith, J.R.; Takeishi, R.; Walpole, P.; Weinmann, R.P.; Wu, H.; Wu, J.; Yin, Z.; Yoon, Y.S.; Zhang, H.G. | Dept. of Physics, Sungkyunkwan University, South Korea; Inst. for Phys.

| ○ | Article | Analyzing the Physical Activity Characteristics of Middle School Students Based On Region (Urban and Rural) and Sex during COVID-19 | PURPOSE This study aimed to analyze physical activity (sedentary, light, moderate to vigorous physical activity [MVPA]) characteristics of middle school students based on region (urban and rural) and sex. METHODS Data were collected from 216 students across 6 middle schools located in medium-sized urban (3 schools) and rural areas (3 schools), and the relevant physical activity was measured using a three-dimensional accelerometer (GT3X model). The collected data were inputted into the SPSS 20.0, and descriptive analysis and two-way ANOVA based on region and gender were performed (<.05). RESULTS The descriptive statistical analysis resulted in the following achievement rate of the physical activity standard (MVPA 60 minutes/day): 9.4%. The two-way ANOVA showed that the main effect according to gender was found in sedentary activity (F=5.258), light activity (F=6.790), and MVPA (F=32.274); furthermore, the main effect according to region was found in light activity (F=10.888) and MVPA (F=7.876). Interaction effect according to region and gender was found at all intensities, and the gap between rural and urban in male students was larger compared to that of female students. CONCLUSIONS After COVID-19, the level of physical activity among adolescents has worsened; this study found the problem of “decrease in physical activity; increase in sedentary activity” to be more serious among male students in urban areas. © Korea Institute of Sport Science. | Lee, Gyu Il | Kyungpook National University, South Korea | 58118889300 | mauri94@knu.ac.kr; | Korean Journal of Sport Science | 1598-2920 | 33 | 4 | 0.15 | 2025-06-25 | 1 | Accelerometer; COVID-19; Middle school student; Physical activity; Region | Korean | Final | 2022 | 10.24985/kjss.2022.33.4.713 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Animal identity and space as represented in South Korean geography textbooks | This paper used content analysis to examine the way that animal identity and space were represented in South Korean world geography textbooks, from which it was found that animals were represented as being a passive result of the natural environment, objects worth preserving, and as a living bio-capital. It was concluded that these perspectives limited the opportunities for students to develop a critical eye when viewing animals. Future animal geography education should allow students to view animals as political and ethical subjects that have their own lives and needs and are even possibly self-aware. Therefore, this study proposes that a more-than-human geography education could provide students with alternative perspectives on animal identity and space. | Cho, Chul-Ki; Kim, Byung-Yeon; Stoltman, Joseph P. | Kyungpook Natl Univ, Dept Geog Educ, Dague Metropolitan City, South Korea; Dasa High Sch, Daegu Metropolitan City, South Korea; Western Michigan Univ, Dept Geog, Kalamazoo, MI 49008 USA | KIM, BYUNGYEON/HTP-3607-2023 | 57221970337; 57221967006; 6602898699 | briet@hanmail.net; | INTERNATIONAL RESEARCH IN GEOGRAPHICAL AND ENVIRONMENTAL EDUCATION | INT RES GEOGR ENVIRO | 1038-2046 | 1747-7611 | 31 | 1 | ESCI | EDUCATION & EDUCATIONAL RESEARCH | 2022 | 1.8 | 0.44 | 2025-06-25 | 3 | 4 | Animal; content analysis; geography textbooks; identity and space of animals; more-than-human geography education | Animal; content analysis; geography textbooks; identity and space of animals; more-than-human geography education | South Korea; animal; geography education; student; textbook | English | 2022 | 2022-01-02 | 10.1080/10382046.2020.1852787 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | Article | Anti-cancer effect of glabridin by reduction of extracellular vesicles secretion in MDA-MB-231 human breast cancer cells | Purpose: Glabridin (GD) is a bio-available isoflavane isolated from the root extract of licorice (Glycyrrhiza glabra L.). It exhibits a variety of pharmacological activities such as antiinflammatory and anti-oxidant activities. However, extracellular vesicles (EVs) secretion and the anti-cancer mechanism of action remains largely unknown. The present study investigates the anticancer effects of GD by determining the inhibition of EVs secretion in the human breast cancer cell line, MDA-MB-231. Methods: Cell viability, reactive oxygen species (ROS) production, migration, invasion rate, and vascular endothelial growth factor (VEGF) concentration were assessed in MDA-MB-231 cells treated with increasing concentrations of GD (0.1, 1, 5, 10, 20 μM). Subsequently, EV secretion and exosomal DEL-1 protein expression were evaluated to determine the anticancer effects of GD. Results: The results showed that GD significantly inhibited the cell proliferation of MDAMB- 231 cells in a dose- or time-dependent manner. Also, ROS production and apoptosis marker protein cleaved caspase-3 were significantly increased in GD-treated MDA-MB-231, compared to control. Furthermore, GD exposure resulted in significantly decreased not only migration and invasion rates but also the VEGF concentration, thereby contributing to a reduction in angiogenesis. Interestingly, the concentration and number of EVs as well as EV marker proteins, such as CD63 and TSG101, were decreased in GD-treated MDA-MB-231 cells. Markedly, extracellular matrix protein DEL-1 as angiogenesis factor was decreased in EVs from GD-treated MDA-MB-231 cells. Conclusion: This study identifies that the anti-cancer molecular mechanism of GD is exerted via inhibition of angiogenesis and EVs secretion, indicating the potential of GD as a chemotherapeutic agent for breast cancer. © 2022 The Korean Nutrition Society. | Choi, Sang-Hun; Hwang, Jin-Hyeon; Baek, Moon-Chang; Cho, Young-Eun | Department of Food Science and Nutrition, Andong National University, Andong, 36729, South Korea; Department of Food Science and Nutrition, Andong National University, Andong, 36729, South Korea; Department of Molecular Medicine, CMRI, School of Medicine, Kyungpook National University, Daegu, 41944, South Korea; Department of Food Science and Nutrition, Andong National University, Andong, 36729, South Korea | 57225948184; 57219012305; 7006013097; 56390104900 | yecho@andong.ac.kr; | Journal of Nutrition and Health | 2288-3886 | 55 | 2 | 0.12 | 2025-06-25 | 1 | apoptosis; breast cancer; extracellular vesicles; glabridin | Korean | Final | 2022 | 10.4163/jnh.2022.55.2.240 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Antiobesity and Hepatoprotective Effects of Protein Hydrolysates Derived from Protaetia brevitarsis in an Obese Mouse Model | Background. Obesity induced by excessive nutrients can cause fatty liver and metabolic dysfunction, which leads to hepatic dysfunction and local/systemic inflammatory responses. Previously, we analyzed the antioxidant, anti-lipotoxicity, and anti-inflammatory effects of protein hydrolysates in vitro. The aim of the present study is to investigate the antiobesity and hepatoprotective effects of protein hydrolysates derived from Protaectia brevitas (PHPB) in an obese mouse model. Methods. For this in vivo study, 40 mice were included and divided into four groups: (1) normal diet group, (2) high-fat-diet (ctrl(-)) group, (3) high-fat-diet and silymarin-treated (ctrl(+)) group, and (4) high-fat-diet and PHPB-treated group. After 6 weeks of treatment, body weight and the amount of daily food intake were observed. Moreover, the major organs and blood of animals were collected for the analysis of serum chemistry, histopathological examination, and obesity- and inflammation-related gene expressions. Results. The body weight and the amount of daily food intake significantly decreased in the PHPB-treated group compared with those in the ctrl(-) group. The levels of serum ALT, AST, ALP, creatinine, blood urea nitrogen, glucose, bilirubin, total cholesterol, TG, low-density lipoprotein, IL-6, TNF-alpha, and IGF-1 significantly reduced in the PHPB-treated group, whereas the serum free fatty acid, albumin, high-density lipoprotein, and adiponectin concentrations increased. In the analysis of weight of the liver, kidney, lungs, spleen, and fat tissues (from epididymal, perirenal, and mesentery tissues), the PHPB-treated group showed decreased values compared with the ctrl(-) group. In the histopathological analysis, the PHPB-treated group showed significantly reduced macrovesicular fatty change and inflammatory cell infiltration in the liver, and the size of the adipocyte in the epididymis also significantly decreased. The obesity- and inflammation-related gene (IL-6, TNF-alpha, IGF-1, leptin, AP2/FABP4, AMPK-alpha 2, beta 3AR, and PPAR-gamma) expressions in the liver and epididymal adipose tissue were reduced in the PHPB-treated group. Conclusions. Overall, the results of this study suggest that the protein hydrolysates that derived from Protaectia brevitas produce antiobesity and hepatoprotective effects via anti-inflammatory activities. | Lee, Eun Hye; Chun, So Young; Yoon, BoHyun; Han, Man-Hoon; Chung, Jae-Wook; Ha, Yun-Sok; Lee, Jun Nyung; Kim, Hyun Tae; Kim, Dae Hwan; Beik, Gyung Yun; Jang, Byung Ik; Kwon, Tae Gyun; Park, Chae-Eun; Lee, In-Seon; Kim, Bum Soo; Lee, Syng-Ook | Kyungpook Natl Univ, Joint Inst Regenerat Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Biomed Res Inst, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu, South Korea; Yeungnam Univ, Dept Lab Anim Res Support Team, Med Ctr, Daegu, South Korea; OkChundang Res Inst, Daegu, South Korea; Yeungnam Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Keimyung Univ, Dept Food Sci & Technol, Daegu, South Korea | Kim, Young-Bo/AAR-8052-2021; Kim, Jihyun/F-6940-2013; Kim, Soo-Yeon/ADR-9663-2022 | 57189661699; 8688166900; 57218931150; 57194067936; 35204798500; 35487226400; 16301364600; 55739531300; 55897992900; 57210204913; 22953491400; 15073765400; 57564453400; 15832174200; 57202817150; 12796984400 | dock97@hanmail.net;synglee@kmu.ac.kr; | BIOMED RESEARCH INTERNATIONAL | 2314-6133 | 2314-6141 | 2022 | 0.66 | 2025-06-25 | 6 | 7 | FATTY LIVER-DISEASE | Adipose Tissue; Animals; Anti-Obesity Agents; Diet, High-Fat; Disease Models, Animal; Fatty Liver; Inflammation; Insulin-Like Growth Factor I; Interleukin-6; Liver; Male; Mice; Mice, Inbred C57BL; Mice, Obese; Obesity; Plant Extracts; Protein Hydrolysates; Tumor Necrosis Factor-alpha; adipocyte protein 2; adiponectin; alanine aminotransferase; albumin; alkaline phosphatase; amp activated protein kinase alpha 1; amp activated protein kinase alpha2; antiobesity agent; aspartate aminotransferase; beta 3 adrenergic receptor; bilirubin; cholesterol; creatinine; fatty acid; fatty acid binding protein 4; glucose; high density lipoprotein; hydroxymethylglutaryl coenzyme A reductase kinase; hydroxymethylglutaryl coenzyme A reductase kinase kinase; interleukin 6; leptin; liver protective agent; low density lipoprotein; peroxisome proliferator activated receptor gamma; protein hydrolysate; silymarin; somatomedin C; triacylglycerol; tumor necrosis factor; unclassified drug; uncoupling protein 2; antiobesity agent; interleukin 6; plant extract; protein hydrolysate; somatomedin C; tumor necrosis factor; alanine aminotransferase blood level; albumin blood level; alkaline phosphatase blood level; animal cell; animal experiment; animal model; animal tissue; antiobesity activity; Article; aspartate aminotransferase blood level; bilirubin blood level; blood biochemistry; blood chemistry; blood sampling; body weight; body weight change; cholesterol blood level; controlled study; creatinine blood level; epididymis fat; fatty acid blood level; food intake; gene expression; glucose blood level; histopathology; in vivo study; kidney weight; lipid diet; lipoprotein blood level; liver protection; liver weight; lung weight; male; mesenteric fat; mouse; nonhuman; obesity; perirenal fat; Protaetia brevitarsis; protein expression; spleen weight; target organ; treatment duration; triacylglycerol blood level; urea nitrogen blood level; adipose tissue; adverse event; animal; C57BL mouse; disease model; fatty liver; inflammation; liver; metabolism; mouse mutant; obesity; pathology | English | 2022 | 2022-03-27 | 10.1155/2022/4492132 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Antioxidant and skin health-enhancing activities of wild indigo (Baptisia tinctoria) root extracts | This study aimed to investigate the effects of wild indigo (Baptisia tinctoria) root extract as a functional food material, in terms of antioxidant and skin health-related activities. Both water and ethanol (50/50, v/v) extracts showed high phenol content. They were evaluated for antioxidant activity, such as 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), antioxidant protection factor (PF), and thiobarbituric acid reactive substances (TBARS). While the DPPH radical scavenging activities of water and ethanol extracts were 84.23% and 89.30%, respectively, at 200 μg/mL total phenol content (TPC), the ABTS radical cation scavenging activities were 51.39% and 48.10%, respectively. The water and ethanol extracts also showed desirable antioxidant PF levels of 1.18 and 1.16, respectively. Furthermore, the antioxidant effects on TBARS significantly increased by 37.31% and 51.43%, respectively, in 200 μg/mL of water and ethanol extracts. Both the extracts showed high dose-dependent collagenase inhibitory activities, up to 27.60% and 77.39%, respectively. The ethanol extract showed an elastase inhibitory activity of 37.21%; the tyrosinase inhibitory effect (which facilitates natural skin-whitening) was 59.26% at 200 μg/mL TPC. The hyaluronidase activity inhibition, related to anti-inflammatory activity, was 20.02% for the water extract and 14.30% for the ethanol extract, at 200 μg/mL TPC. Therefore, B. tinctoria extract has potential applications in cosmetics and food supplements due to its antioxidant and skin health promoting activities.

| ○ | Review | Aortic Arch Variants and Anomalies: Embryology, Imaging Findings, and Clinical Considerations | There is a wide spectrum of congenital anomalies or variations of the aortic arch, ranging from non-symptomatic variations that are mostly detected incidentally to clinically symptomatic variations that cause severe respiratory distress or esophageal compression. Some of these may be accompanied by other congenital heart diseases or chromosomal anomalies. The widespread use of multidetector computed tomography (CT) in clinical practice has resulted in incidental detection of several variations of the aortic arch in adults. Thus, radiologists and clinicians should be aware of the classification of aortic arch anomalies and carefully look for imaging features associated with a high risk of clinical symptoms. Understanding the embryological development of the aortic arch aids in the classification of various subtypes of aortic arch anomalies and variants. For accurate diagnosis and precise evaluation of aortic arch anomalies, cross-sectional imaging modalities, such as multidetector CT or magnetic resonance imaging, play an important role by providing three-dimensional reconstructed images. In this review, we describe the embryological development of the thoracic aorta and discuss variations and anomalies of the aortic arch along with their clinical implications. © 2022 Korean Society of Echocardiography. | Bae, Sang Bin; Kang, Eun-Ju; Choo, Ki Seok; Lee, Jongmin; Kim, Sang Hyeon; Lim, Kyoung Jae; Kwon, Heejin | Department of Radiology, College of Medicine, Dong-A University, Busan, South Korea; Department of Radiology, College of Medicine, Dong-A University, Busan, South Korea; Department of Radiology, Pusan National University, School of Medicine, Pusan National University Yangsan Hospital, Yangsan, South Korea; Department of Radiology, Kyungpook National University, School of Medicine, Daegu, South Korea; Department of Radiology, College of Medicine, Dong-A University, Busan, South Korea; Department of Radiology, College of Medicine, Dong-A University, Busan, South Korea; Department of Radiology, College of Medicine, Dong-A University, Busan, South Korea | 58170455800; 8395421600; 8667651300; 55689919700; 55862526900; 56506121500; 57216225468 | medcarrot@dau.ac.kr; | Journal of Cardiovascular Imaging | 2586-7210 | 30 | 4 | 1.24 | 2025-06-25 | 18 | Aorta; Congenital abnormalities; Multidetector computed tomography; Technology | adult; aneurysm; angina pectoris; aortic arch anomaly; aortic dissection; aortic occlusion; artery compression; body mass; brachiocephalic trunk; chromosome aberration; common carotid artery; computed tomographic angiography; congenital heart disease; controlled study; conventional angiography; coronary artery anomaly; diagnostic test accuracy study; DiGeorge syndrome; Down syndrome; echocardiography; embryology; endotracheal intubation; familial hypercholesterolemia; female; gestational age; heart development; heart ventricle septum defect; hemodynamics; human; male; microarray analysis; multidetector computed tomography; nuclear magnetic resonance imaging; patent ductus arteriosus; pulmonary valve atresia; radiation exposure; respiratory distress; resuscitation; Review; syndrome CHARGE; systematic review; thoracic aorta; three-dimensional imaging; tracheoesophageal fistula; transthoracic echocardiography; tricuspid valve atresia; Turner syndrome; x-ray computed tomography | English | Final | 2022 | 10.4250/jcvi.2022.0058 | 바로가기 | 바로가기 |
