| ○ | ○ | Article | Nationwide Multicenter Study of Eosinophilic Esophagitis in Korean Children | Purpose: In East Asian countries, there are only a few epidemiologic studies of eosinophilic esophagitis (EoE) and no studies in children. We investigated the incidence and compared the clinical characteristics of EoE and eosinophilic gastroenteritis involving the esophagus (EGEIE) in Korean children. Methods: A total of 910 children, who had symptoms of esophageal dysfunction, from 10 hospitals in Korea were included. EoE was diagnosed according to diagnostic guidelines and EGEIE was diagnosed when there were >15 eosinophils in the esophagus per high power field (HPF) and >20 eosinophils per HPF deposited in the stomach and duodenum with abnormal endoscopic findings. Results: Of the 910 subjects, 14 (1.5%) were diagnosed with EoE and 12 (1.3%) were diagnosed with EGEIE. Vomiting was the most common symptom in 57.1% and 66.7% of patients with EoE and EGEIE, respectively. Only diarrhea was significantly different between EoE and EGEIE (p=0.033). In total, 61.5% of patients had allergic diseases. Exudates were the most common endoscopic findings in EoE and there were no esophageal strictures in both groups. The median age of patients with normal endoscopic findings was significantly younger at 3.2 years, compared to the median age of 11.1 years in those with abnormal endoscopic findings (p=0.004). Conclusion: The incidence of EoE in Korean children was lower than that of Western countries, while the incidence of EGEIE was similar to EoE. There were no clinical differences except for diarrhea and no differences in endoscopic findings between EoE and EGEIE. | Lee, Kunsong; Choe, Byung-Ho; Kang, Ben; Kim, Seung; Kim, Jae Young; Shim, Jung Ok; Lee, Yoo Min; Lee, Eun Hye; Jang, Hyo-Jeong; Ryoo, Eell; Yang, Hye Ran | Dankook Univ, Dept Pediat, Coll Med, Cheonan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Yonsei Univ, Severance Childrens Hosp, Dept Pediat, Coll Med, Seoul, South Korea; Gyeongsang Natl Univ, Dept Pediat, Changwon Hosp, Chang Won, South Korea; Korea Univ, Dept Pediat, Guro Hosp, Seoul, South Korea; Soonchunhyang Univ, Dept Pediat, Bucheon Hosp, Bucheon, South Korea; Eulji Univ, Nowon Eulji Med Ctr, Dept Pediat, Sch Med, Seoul, South Korea; Keimyung Univ, Dept Pediat, Sch Med, Daegu, South Korea; Gachon Univ, Dept Pediat, Gil Med Ctr, Incheon, South Korea; Seoul Natl Univ, Dept Pediat, Bundang Hosp, Sungnam, South Korea; Seoul Natl Univ, Dept Pediat, Coll Med, Seoul, South Korea | ; Yang, Hye/J-5533-2012; Choe, Byung-Ho/KSM-6251-2024; 康, 奔/JMQ-0812-2023 | 55911172700; 57574977300; 57194823199; 57196230792; 57203251636; 57022898300; 55588928200; 57188855950; 55355948500; 19837506900; 57049781100 | hryarg@snubh.org;hryang@snubh.org; | PEDIATRIC GASTROENTEROLOGY HEPATOLOGY & NUTRITION | PEDIATR GASTROENTERO | 2234-8646 | 2234-8840 | 23 | 3 | ESCI | PEDIATRICS | 2020 | N/A | 0.36 | 2025-06-25 | 8 | 8 | Eosinophilic esophagitis; Eosinophilic gastroenteritis; Incidence; Child | CONSENSUS RECOMMENDATIONS; PREVALENCE; MANAGEMENT; DIAGNOSIS; ADULTS; GASTROENTERITIS; GUIDELINES; GASTRITIS; FEATURES; COLITIS | Child; Eosinophilic esophagitis; Eosinophilic gastroenteritis; Incidence | English | 2020 | 2020-05 | 10.5223/pghn.2020.23.3.231 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Natural soluble human leukocyte antigen class I in donor serum neutralizes donor-specific HLA alloantibodies in recipient serum | Background Human leukocyte antigen (HLA) molecules are cell-bound but can be identified in a soluble form. These soluble HLA (sHLA) molecules have an immunomodulatory function. We investigated whether natural sHLA in donor serum can neutralize donor-specific HLA alloantibodies (DSAs) in recipient serum. Methods Neutralizing effects of donor serum on DSAs in recipient serum were measured using inhibition assay principle of flow cytometric crossmatch (FCXM), performed using sera from 143 kidney transplant recipients and their donors. The adding of donor serum to recipient serum yielded lower mean fluorescence intensity (MFI) ratios (test/control) than when diluent was added [Roswell Park Memorial Institute (RPMI) or third-party serum], which was presumed to be caused by the neutralizing effects of sHLA. Results In the recipient group with class I DSAs alone (N=14), donor serum addition to recipient serum resulted in lower T cell MFI ratios [2.25 (1.31-32.51)] than those observed on RPMI addition [3.04 (1.33-125.39), P 0.05 for both. Conclusions Using inhibition FCXM, we verified that natural sHLA class I in donor serum neutralizes DSAs in recipient serum. However, no neutralizing effects of sHLA class II were revealed in this study. These potentially beneficial effects of sHLA infused via blood-derived products should be considered when desensitizing highly HLA-sensitized patients. | Won, Dong Il; Lee, Nan Young; Lim, Jeong-Hoon; Han, Young Seok; Kim, Chan-Duck; Huh, Seung | Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | Kim, Hyoungnae/JXN-1329-2024; Lim, Jeong-Hoon/ABE-6003-2020; lee, nan/HZM-0321-2023 | 7005166517; 57209204358; 55360244300; 7404096216; 8558530700; 7101832929 | wondi@knu.ac.kr; | BLOOD RESEARCH | BLOOD RES | 2287-979X | 2288-0011 | 55 | 2 | ESCI | HEMATOLOGY | 2020 | N/A | 0.05 | 2025-06-25 | 3 | 3 | Soluble HLA; Donor-specific HLA alloantibody; Neutralization; Flow cytometric crossmatch | BLOOD-TRANSFUSION; TRANSPLANTATION; ANTIBODY; QUANTITATION | Donor-specific HLA alloantibody; Flow cytometric crossmatch; Neutralization; Soluble HLA | HLA antibody; HLA antigen class 1; neutralizing antibody; adult; aged; Article; B lymphocyte; blood group typing; controlled study; dilution; female; flow cytometry; fluorescence analysis; graft recipient; human; human cell; kidney donor; major clinical study; male; middle aged; serum; T lymphocyte; very elderly | English | 2020 | 2020-06 | 10.5045/br.2020.2020031 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Book chapter | Non-microbial carbonate precipitation as an improvement technique of sand | In this study, the formation of artificial Calcium Carbonate (CaCO3) from the reaction between Calcium Hydroxide (CH) and Carbon Dioxide (CO2) was taken into account to improve sand properties. Firstly, Jumunjin sand was mixed with 2% of CH and water at a constant water-solid weight ratio of 0.1 before curing in a carbon dioxide chamber. The precipitated calcite content was investigated by the variation of CO2 chamber pressure and number of repeatable treatment. Then, unconfined compression tests of such samples were carried out to evaluate the influence of calcite content on mechanical properties of sand. It indicated that as increasing of repeatable treatment, the UCS of treated sand increased due to the higher of calcite precipitation. The first and fifth cycle do not lead to any significant variations of precipitated calcium carbonate content (CCC) and unconfined compressive strength (UCS) with the change of carbon dioxide chamber pressure from 100 kPa to 200 kPa, but- the higher CCC and UCS can be seen clearly at the tenth cycle. After 10 treated cycles, the UCS of CP1.10 and CP2.10 were 5 times greater than CP1.1 and CP2.1, respectively. The maximum UCS was 361 kPa of CP2.10 specimen. The stress-strain curves obtained from UCS test at 200 kPa CO2 gas pressure exhibited more strain at peak stress than that at 100 kPa and the samples subjected to 10 treated cycles has more ductile behavior than other samples. © Springer Nature Singapore Pte Ltd. 2020. | Park, Sung-Sik; Le, Trung-Tri; Kim, Seong-Heon; Nong, Zhenzhen | Dept. of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea; Dept. of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea; Dept. of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea; Dept. of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea | 36241850300; 57211376067; 57211376260; 57211377923 | ltrungtri@gmail.com; | Lecture Notes in Civil Engineering | 2366-2557 | 54 | 0 | 2025-06-25 | 0 | Calcium carbonate binder; Compressive strength; Mechanical properties | Calcite; Calcium carbonate; Carbonation; Compression testing; Compressive strength; Hydrated lime; Lime; Mechanical properties; Sand; Stress-strain curves; Calcite precipitation; Chamber pressure; Ductile behavior; Improvement technique; Microbial carbonates; Precipitated calcium carbonate; Unconfined compression tests; Unconfined compressive strength; Carbon dioxide | English | Final | 2020 | 10.1007/978-981-15-0802-8_135 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Non-Shared Bottleneck Links of MPTCP: Bottleneck detection and congestion control | Multipath TCP (MPTCP) should perform better than single path TCP in non-shared bottleneck (NSB) links and have the same throughput in shared bottleneck links. The effort of MPTCP congestion control, which does not harm the single-path TCP, rather hinders the achievement of an ideal throughput in NSB links. In this paper, we propose a method to detect the bottleneck bottleneck-type of MPTCP connection, and accordingly propose BALIA for NSB (NSB-BALIA) to improve the throughput in NSB links. Through emulation evaluation, we confirmed that NSB-BALIA improved the throughput in the SB link without harming single-path TCP and achieved an ideal throughput ratio in the NSB links than that in the existing MPTCP congestion control algorithms. | Kim, Geon-Hwan; Song, Yeong-Jun; Park, Chang-Hoon; Eom, Won-Ju; Kim, Jeong-Keun; Cho, You-Ze | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57189040274; 57210919165; 57221384913; 57221382871; 57221376838; 7404469829 | kgh76@ee.knu.ac.kr;syj5385@knu.ac.kr;pch4495@knu.ac.kr;dnjswn9612@knu.ac.kr;kjg818@knu.ac.kr;yzcho@knu.ac.kr; | 11TH INTERNATIONAL CONFERENCE ON ICT CONVERGENCE: DATA, NETWORK, AND AI IN THE AGE OF UNTACT (ICTC 2020) | 2162-1233 | 0.45 | 2025-06-25 | 2 | 3 | Multipath TCP; congestion control; shared bottleneck; non-shared bottleneck | congestion control; Multipath TCP; non-shared bottleneck; shared bottleneck | Transmission control protocol; Bottleneck detection; Bottleneck link; Multipath TCP; Single path; Traffic congestion | English | 2020 | 2020 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Article | Novel voltage balancer for half-bridge configuration DAB converter | This paper proposes an application of artificial neural networks for analyzing electricity market that has insufficient information for calculating equilibrium. Neural networks are constructed and trained on two representative cases in the electricity market. One is for calculating equilibrium price in perfect competition market and the other is for determining whether the transmission congestion occurs. The neural network uses a multilayer structure and learns with backpropagation algorithms for training. The neural networks trained in the case studies calculate the market price with a high probability and also determines an occurrence of the transmission congestion accurately. © 2020 Korean Institute of Electrical Engineers.

| ○ | Article | Numerical method for effective strength of nodal zones in two-dimensional strut-and-tie models | For an appropriate strut-and-tie model design of structural concrete, the effective strengths of nodal zones must be determined with sufficient accuracy. Many values and equations for effective strengths have been suggested. However, since the recommended strength values have been determined based on experimental works with specific geometry and loading conditions, it is inappropriate to use them in the strut-and-tie model design of general structural concretes. In this study, a new numerical method, that evaluates the effective strengths of two-dimensional nodal zones accurately and consistently by reflecting the state of stresses in the nodal zones, the effects of stresses and details of reinforcing bars placed inside and around nodal zones, and the compressive strength of concrete, is proposed. The ultimate strengths of 434 reinforced concrete deep beams tested to failure were estimated to verify the validity of the proposed method using the ACI 445 strut-and-tie model method with the existing and proposed effective strengths of nodal zones. © 2020 by Korea Concrete Institute. | Yun, Young Mook | Department of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea | 7201731110 | ymyun@knu.ac.kr; | Journal of the Korea Concrete Institute | 1229-5515 | 32 | 4 | 0.16 | 2025-06-25 | 2 | Deep beam; Effective strength; Nodal zone; Structural concrete; Strut-and-tie model | Korean | Final | 2020 | 10.4334/jkci.2020.32.4.359 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Nutritional value and antioxidant potential of lemon seed and sprout | High amounts of lemon seeds are discarded as by-products of processing industries. It is important to find some measures, whereby they could be used in value-added ways. Although few studies have been conducted on lemon seed oils, no study has been conducted on the nutrient content of lemon seed sprouts. The objective of this study was to investigate the nutritional value and antioxidant potential of lemon seeds and sprouts. The 1,1-diphenly-2-picrylhydrazyl radical-scavenging potential, total polyphenol, and total free amino acid content were higher in the sprouts than in the seeds. Similarly, the content of such mineral elements as Fe, Na, and Zn, increased with germination. However, salicylic acid and total mineral content were lower in the sprouts than in the seeds. The results indicate that lemon seeds and sprouts could be regarded as high-value materials in food and cosmetic industries. © The Korean Society of Food Science and Technology | Park, Yong-Sung; Dhungana, Sanjeev Kumar; Kim, Il-Doo; Shin, Dong-Hyun | School of Applied Biosciences, Kyungpook National University, South Korea; Department of Southern Area Crop Science, National Institute of Crop Science, Rural Development Administration; International Institute of Agricultural Research and Development, Kyungpook National University, South Korea; School of Applied Biosciences, Kyungpook National University, South Korea | 57195726535; 56269940800; 56269995600; 7403352903 | dhshin@knu.ac.kr; | Korean Journal of Food Science and Technology | 0367-6293 | 52 | 6 | 0.08 | 2025-06-25 | 5 | Antioxidant potential; Cosmetic industry; Lemon seed; Nutritional value; Sprout | English | Final | 2020 | 10.3839/10.9721/kjfst.2020.52.6.641 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | Object Detection Using Vision and LiDAR Sensor Fusion for Multi-channel V2X System | In this paper, we propose an algorithm that recognizes the environment around the vehicle using Vision and LiDAR sensor fusion, and extracts the object affecting the multichannel V2X communication system and transmits information to the TCU. A general object detection algorithm for autonomous vehicle detects pedestrians, signs, vehicles. However, in this paper, we detect the surroundings that affect the communication performance. For example, the detection targets are not only a bulky vehicle such as a large truck or bus but also a bulky structure such as a building, a tunnel or a soundproof wall. The proposed method has the three steps. The first is receiving cameras and LiDAR sensors and to preprocess the data from each sensor. In this step, the distortion of image data is calibrated, and the LiDAR sensor separates the ground point group and the non-ground point group. The second step is sensor fusion. The coordinate system is integrated into a transformation matrix between two predetermined sensors, and the results of the two data are fused. The last step is object classification using CNN. The proposed method can improve the reliability and stability of communication by detecting the objects affecting the communication performance in advance and changing the channel parameters of the multichannel TCU. © 2020 IEEE. | Lee, Gyu Ho; Choi, Ji Dong; Lee, Jong Hyuk; Kim, Min Young | School of Electronic Engineering, Kyungpook National University, Daegu, South Korea; School of Electronic Engineering, Kyungpook National University, Daegu, South Korea; School of Electronic Engineering, Kyungpook National University, Daegu, South Korea; School of Electronic Engineering, Kyungpook National University, Daegu, South Korea | 57210916749; 57216614368; 57208132362; 56739349100 | 2020 International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2020 | 1.34 | 2025-06-25 | 15 | LiDAR; Multi-channel V2X; Object Detection; Sensor Fusion; Vision | Artificial intelligence; Linear transformations; Metadata; Object detection; Object recognition; Optical radar; Point groups; Vehicles; Channel parameter; Co-ordinate system; Communication performance; Detection targets; Object classification; Object detection algorithms; Reliability and stability; Transformation matrices; Vehicle to vehicle communications | English | Final | 2020 | 10.1109/icaiic48513.2020.9065243 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | ○ | Article | Object-based Building Change Detection Using Azimuth and Elevation Angles of Sun and Platform in the Multi-sensor Images | Building change monitoring based on building detection is one of the most important fields in terms of monitoring artificial structures using high-resolution multi-temporal images such as CAS500-1 and 2, which are scheduled to be launched. However, not only the various shapes and sizes of buildings located on the surface of the Earth, but also the shadows or trees around them make it difficult to detect the buildings accurately. Also, a large number of misdetection are caused by relief displacement according to the azimuth and elevation angles of the platform. In this study, object-based building detection was performed using the azimuth angle of the Sun and the corresponding main direction of shadows to improve the results of building change detection. After that, the platform's azimuth and elevation angles were used to detect changed buildings. The object-based segmentation was performed on a high-resolution imagery, and then shadow objects were classified through the shadow intensity, and feature information such as rectangular fit, Gray-Level Co-occurrence Matrix (GLCM) homogeneity and area of each object were calculated for building candidate detection. Then, the final buildings were detected using the direction and distance relationship between the center of building candidate object and its shadow according to the azimuth angle of the Sun. A total of three methods were proposed for the building change detection between building objects detected in each image: simple overlay between objects, comparison of the object sizes according to the elevation angle of the platform, and consideration of direction between objects according to the azimuth angle of the platform. In this study, residential area was selected as study area using high-resolution imagery acquired from KOMPSAT-3 and Unmanned Aerial Vehicle (UAV). Experimental results have shown that F1-scores of building detection results detected using feature information were 0.488 and 0.696 respectively in KOMPSAT-3 image and UAV image, whereas F1-scores of building detection results considering shadows were 0.876 and 0.867, respectively, indicating that the accuracy of building detection method considering shadows is higher. Also among the three proposed building change detection methods, the F1-score of the consideration of direction between objects according to the azimuth angles was the highest at 0.891. | Jung, Sejung; Park, Jueon; Lee, Won Hee; Han, Youkyung | Kyungpook Natl Univ, Dept Spatial Informat, Daegu, South Korea; Kyungpook Natl Univ, Sch Convergence & Fus Syst Engn, Daegu, South Korea | Jung, Sejung/NRB-6938-2025 | 57209137546; 57218222782; 57190774365; 55457676600 | han602@knu.ac.kr; | KOREAN JOURNAL OF REMOTE SENSING | KOREAN J REMOTE SENS | 1225-6161 | 2287-9307 | 36 | 5 | ESCI | REMOTE SENSING | 2020 | N/A | 0.41 | 2025-06-25 | 3 | 6 | Object-based building detection; Azimuth angle; Elevation angle; Shadow | LIDAR DATA; SATELLITE IMAGES; EXTRACTION; SHADOW | Azimuth angle; Elevation angle; Object-based building detection; Shadow | Korean | 2020 | 2020-10 | 10.7780/kjrs.2020.36.5.2.12 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Proceedings Paper | Observation of structural color in random Au nano-islands fabricated on dielectric nanopillars | Industrial promising structural colors based on subwavelength scale structure inevitably entail very high fabrication costs in artificial implementation. To reduce the costs, we fabricated the microstructure that necessary to realize the structural color through Au nano-islands, which can be manufactured by bottom-up chemical process instead of strict top-down process and developed a device that can adjust color quantitatively. Notably, this device has the color tunability through the refractive index of the solution that infiltrates the device and is expected to be used in the field of sensors or anti-counterfeiting devices. | Bae, Young-Gyu; Kim, Taehyun; Lee, Jongsu; Yu, Eui-Sang; Ryu, Yong-Sang; Lee, Seung-Yeol | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Korea Inst Sci & Technol, Sensor Syst Res Ctr, 5 Hwarang Ro 14 Gil, Seoul 02792, South Korea | ; Yu, Eui-Sang/GVR-7972-2022; Ryu, Yong-Sang/AAI-3948-2020 | 57204432013; 59783064600; 58175758800; 56297930000; 55229727000; 55881869300 | OPTICAL MANIPULATION AND STRUCTURED MATERIALS CONFERENCE 2020 | 0277-786X | 1996-756X | 11522 | 0 | 2025-06-25 | 0 | 0 | structural color; sensor; optical camouflage; anti-counterfeit; Fabry-Perot cavity | Anti-counterfeit; Fabry-perot cavity; Optical camouflage; Sensor; Structural color | Fabrication; Nanopillars; Nanosensors; Refractive index; Anti-counterfeiting; Chemical process; Color tunability; Fabrication cost; Nano-islands; Structural color; Subwavelength-scale structures; Top-down process; Color | English | 2020 | 2020 | 10.1117/12.2573799 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Occurrence of the lowermost part of the Yucheon Group and its SHRIMP U-Pb ages in Hyeonpoong and Bugok areas | The Cretaceous Yucheon Group is volcano-sedimentary successions that are formed by volcanic activities of the Gyeongsang Volcanic Arc. Lack of the detailed field researches on the Yucheon Group results in poor understanding of the formation time and the tempo-spatial development of the volcanic arc. Also, this causes difficulties to reconstruct the depositional history from the Sindong and Hayang groups to the Yucheon Group. In this study, we conducted field research targeting to the interface between topmost part of the Hayang Group and the lowermost part of the Yucheon Group from Hyeonpoong to Bugok areas. We also identified depositional timing of the lowermost part of the Yucheon Group using SHRIMP U-Pb zircon age dating. This Yucheon Group is composed of tuff and lapilli tuff, conformably overlying the Jindong Formation. The results of SHRIMP U-Pb zircon age are 97 to 96 Ma, indicating cessation of deposition of the Hayang Group at 97 to 96 Ma by input of pyroclastic materials into the Jinju Subbasin during the explosive volcanic eruptions from the Gyeongsang Volcanic Arc. In comparison with field researches and results of LA-ICP-MS zircon U-Pb age dating (88-85 Ma) of the lowermost part of the Yucheon Group in Gyeongju areas, the volcanic activities that formed Yucheon Group and their influence ranges varied tempo-spatially. This is probably due to distance difference from the volcanic arc or establishment of the paleo-drainage system from the Gyeongsang Volcanic Arc to nearby lowlands. | Ghim, Yong Sik; Ko, Kyoungtae; Lee, Byung Choon | Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Geol Div, Daejeon 34132, South Korea | 57210284942; 56652511400; 55945123900 | kkt@kigam.re.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 53 | 4 | ESCI | GEOLOGY | 2020 | N/A | 0.51 | 2025-06-25 | 8 | 8 | late cretaceous; yucheon group; gyeongsang volcanic arc; volcanic activities; jindong formation | CRETACEOUS GYEONGSANG BASIN; SOUTH CHINA; ZIRCON GEOCHRONOLOGY; TECTONIC EVOLUTION; DEPOSITIONAL AGE; KOREAN PENINSULA; KYONGSANG BASIN; SYSTEM; MARGIN; STRATIGRAPHY | Gyeongsang volcanic arc; Jindong formation; Late cretaceous; Volcanic activities; Yucheon group | Korean | 2020 | 2020-08 | 10.9719/eeg.2020.53.4.397 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
