| ○ | Article | SAMBA: Synthetic Data-Augmented Mamba-Based Change Detection Algorithm Using KOMPSAT-3A Imagery | Change detection is essential for applications such as urban planning, environmental monitoring, and disaster response. Despite advancements in high-resolution satellite imagery, accurate change detection remains challenging due to increased landscape heterogeneity and variable atmospheric conditions. The Mamba model, an efficient state-space model-based architecture, has shown promise in capturing spatiotemporal relationships in high-resolution datasets, addressing the limitations of traditional methods that struggle with the diverse appearances of urban structures. This research investigates applying Mamba to multitemporal Korea Multi-Purpose Satellite (KOMPSAT) imagery, using both real and synthetic data from SyntheWorld, a dataset developed to simulate various change scenarios. This study introduces a synthetic data-augmented mamba-based change detection algorithm (SAMBA), designed to detect structural changes in urban environments using KOMPSAT-3A satellite imagery. The main objectives are to evaluate the Mamba binary change detection (MambaBCD) model’s ability to detect building changes in KOMPSAT-3A images and assess the impact of synthetic data augmentation on performance. Experimental results with MambaBCD-Small and MambaBCD-Tiny models indicate that synthetic data incorporation improves generalization in complex settings, achieving high performance across multiple data and model configurations. Notably, the MambaBCD-Tiny model, with or without synthetic augmentation, outperformed the larger-parameter MambaBCD-Small model, demonstrating enhanced sensitivity in detecting satellite image changes. Performance evaluation metrics yielded an overall accuracy of 99.73%, precision of 98.34%, recall of 96.54%, F1-score of 97.43%, intersection over union of 95.00%, and Kappa coefficient of 97.29%. These metrics were similarly used to test the SAMBA algorithm’s generalization on benchmark change detection datasets, showcasing its potential as a robust tool for high-resolution image change detection. © 2024 Korean Society of Remote Sensing. | Tobias, Rogelio Ruzcko; Bae, Sejeong; Cho, Hwanhee; Im, Jungho | Artificial Intelligence Graduate School, Ulsan National Institute of Science and Technology, Ulsan, South Korea; Department of Civil, Urban, Earth, and Environmental Engineering, Ulsan National Institute of Science and Technology, Ulsan, South Korea; Department of Convergence and Fusion System Engineering, Kyungpook National University, Sangju, South Korea | 57216463775; 58705532200; 59507970700; 9036557400 | ersgis@unist.ac.kr; | Korean Journal of Remote Sensing | KOREAN J REMOTE SENS | 1225-6161 | 2287-9307 | 40 | 6 | ESCI | REMOTE SENSING | 2024 | 0.4 | 91.5 | 0.46 | 2025-05-07 | 1 | Artificial intelligence; Change detection; Computer vision; KOMPSAT; Mamba; Remote sensing | English | Final | 2024 | 10.7780/kjrs.2024.40.6.3.11 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Primary and secondary prevention of stroke and cardiovascular events using evolocumab and alirocumab: Meta-analysis of randomized controlled trials | Objectives: Although the clinical role of protein convertase subtilisin kexin type 9 (PCSK9) inhibitors for cholesterol management is increasing, the postmarketing period of use is short compared to other lipid-lowering drugs, so there is still insufficient evidence for their efficacy and safety. In this meta -analysis, we evaluated preventive effects of stroke and cardiovascular (CV) events using evolocumab and alirocumab. Materials and methods: We assessed the relative risk of stroke and CV events after alirocumab or evolocumab treatment in individuals with or without clinical CV diseases compared with that in controls. In addition, we evaluated the relative risk of hemorrhagic stroke. Results: A total of 25 articles were included (median of study duration = 52 weeks). The risk of stroke was significantly decreased after treatment with alirocumab or evolocumab (primary prevention in patients without CV diseases: RR = 0.733; 95% CI, 0.618 - 0.870; secondary prevention in patients with CV diseases: RR = 0.703; 95% CI, 0.562 - 0.880). The risk of CV events also significantly decreased in patients treated with alirocumab or evolocumab (primary prevention: RR = 0.818; 95% CI, 0.777 - 0.861; secondary prevention: RR = 0.725; 95% CI, 0.578 - 0.910). The relative risk of hemorrhagic stroke was not significantly different between PCSK9 inhibitor-treated patients and controls (RR = 1.041; 95% CI, 0.690 - 1.573). Conclusion: Our findings indicate that evolocumab and alirocumab are significantly effective without increasing the risk of hemorrhagic stroke. Based on this, the PCSK9 inhibitors can be highly recommended for cholesterol management. | Shin, Kwang-Hee; Choi, Hye Duck | Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Daegu, South Korea; Yeungnam Univ, Coll Pharm, Gyeongbuk, South Korea; Yeungnam Univ, Coll Pharm, 280 Daehak Ro, Gyongsan 38541, Gyeongbuk, South Korea | 35216279300; 36877353300 | chd80@hotmail.com; | INTERNATIONAL JOURNAL OF CLINICAL PHARMACOLOGY AND THERAPEUTICS | INT J CLIN PHARM TH | 0946-1965 | 62 | 6 | SCIE | PHARMACOLOGY & PHARMACY | 2024 | 0.7 | 91.9 | 0 | 2025-05-07 | 0 | 0 | alirocumab; evolocumab; stroke; cardiovascular; meta-analysis | HETEROZYGOUS FAMILIAL HYPERCHOLESTEROLEMIA; RISK PATIENTS; JAPANESE PATIENTS; PCSK9 INHIBITORS; AMG 145; ADD-ON; LDL-C; EFFICACY; SAFETY; STATINS | alirocumab – evolocumab; cardiovascular; meta-analysis; stroke | Antibodies, Monoclonal; Antibodies, Monoclonal, Humanized; Anticholesteremic Agents; Cardiovascular Diseases; Humans; PCSK9 Inhibitors; Primary Prevention; Proprotein Convertase 9; Randomized Controlled Trials as Topic; Secondary Prevention; Stroke; Treatment Outcome; alirocumab; evolocumab; hydroxymethylglutaryl coenzyme A reductase inhibitor; alirocumab; evolocumab; hypocholesterolemic agent; monoclonal antibody; PCSK9 inhibitor; PCSK9 protein, human; proprotein convertase 9; Article; brain hemorrhage; cardiovascular disease; cerebrovascular accident; clinical feature; drug efficacy; human; meta analysis; primary prevention; randomized controlled trial (topic); risk factor; secondary prevention; cardiovascular disease; cerebrovascular accident; epidemiology; prevention and control; primary prevention; procedures; randomized controlled trial (topic); treatment outcome | English | 2024 | 2024-06 | 10.5414/cp204506 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Study on the Retrospective Reinterpretation of BRCA1 and BRCA2 Variants | Background: Hereditary breast/ovarian cancer is associated with BRCA gene mutations. As large volumes of clinical data on BRCA variants are continuously updated, their clinical interpretation may change, leading to their reclassification. This study analyzed the class and proportion of the changed clinical interpretations of BRCA variants to validate the need for periodic reviews of these variants. Methods: This retrospective study reinterpreted previously reported BRCA1 and BRCA2 exon variants according to the 2015 American College of Medical Genetics and Genomics guidelines and the clinical significance of the recent public genomic database. Reanalyzed results were obtained for patients tested for BRCA genetic mutation for 10 years and 4 months. Results: We included data from 4,058 patients, with 595 having at least one pathogenic variant (P), likely pathogenic variant (LP), or variant of uncertain significance (VUS) at a detection rate of 14.66%. The numbers of exon and intron variants were 562 (87.81%) and 78 (12.19%), respectively. BRCA1 exhibited a significantly higher P/LP detection rate of 6.96% compared to that of BRCA2 at 6.89% (p < 0.001). Conversely, BRCA2 demonstrated a significantly higher VUS rate of 10.38% compared to that of BRCA1 at 5.08% (p < 0.001). Among BRCA1 mutations, substitutions were the most prevalent in P/LP and VUS. Among BRCA2 mutations, deletions were most prevalent in P/LP, and substitutions were most prevalent in VUS. Among the 131 patients with P/LP in BRCA1 exons, the clinical interpretation was reclassified in two cases (1.53%), one VUS and one benign/likely benign (B/LB), and 48 cases (48.00%) with VUS were reclassified; one to P/LP and 47 to B/LB. Among the 138 patients with P/LP in BRCA2 exons, the clinical interpretation was reclassified in six (4.35%), five to VUS, and one to B/LB, and all 74 with VUS were reclassified to B/LB. Conclusions: We determined the class and proportion of reclassified BRCA variants. In conclusion, reviews are required to provide clinical guidance, such as determining treatment direction and preventive measures in the future. | Kim, Jin Ju; Kim, Dong Ja; Nam, Eon Jeong; Song, Kyung Eun; Ham, Ji Yeon; Kim, Yu Kyung; Lee, Nan Young | Kyungpook Natl Univ, Grad Sch Forens & Invest Sci, Dept Medicolegal Invest, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Forens Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Rheumatol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Lab Med, 807 Hoguk Ro, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea | 58993259800; 57282881600; 7005824293; 57843936100; 56464754800; 9237571900; 57209204358 | leenanyoung70@gmail.com; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 70 | 4 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2024 | 0.6 | 92.4 | 0 | 2025-04-16 | 0 | 0 | breast/ovarian cancer; BRCA1; BRCA2; P; LP; VUS; reclassified | BREAST-CANCER; UNCERTAIN SIGNIFICANCE; SEQUENCE VARIANTS; GUIDELINES; STANDARDS; GENE | BRCA1; BRCA2; breast/ovarian cancer; LP; P; reclassified; VUS | BRCA1 Protein; BRCA2 Protein; Breast Cancer, Familial; Breast Neoplasms; Female; Genetic Predisposition to Disease; Genetic Testing; Humans; Mutation; Ovarian Neoplasms; Retrospective Studies; alcohol; BRCA1 protein; BRCA2 protein; genomic DNA; BRCA1 protein; BRCA1 protein, human; BRCA2 protein; BRCA2 protein, human; alcohol consumption; Article; breast feeding; childbirth; classification; clinical assessment; comparative study; data interpretation; DNA sequencing; exon; female; frequency analysis; gene deletion; gene mutation; genetic variability; hereditary breast and ovarian cancer syndrome; high throughput sequencing; human; intron; Korea; lifestyle; major clinical study; multiplex polymerase chain reaction; obesity; practice guideline; retrospective study; validation study; Western diet; breast tumor; genetic predisposition; genetic screening; genetics; mutation; ovary tumor; pathology; procedures | English | 2024 | 2024 | 10.7754/clin.lab.2023.230911 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Changes in the Distribution of Pathogens Causing Meningoencephalitis Before and During the COVID-19 Pandemic | Background: Infectious meningoencephalitis (ME) is a major global health concern. Viruses are the most frequently implicated etiologies, whereas bacterial causes, although life-threatening, constitute a lesser proportion of ME cases, together with other pathogens. The strict implementation of COVID-19 mitigation measures led to the decreased viral and non-viral infectious diseases. Therefore, this study aimed to investigate the effect of these measures on ME-causing pathogens by age groups. Methods: This retrospective study aimed to determine and compare the rates of pathogen-positive ME cases during the pre-pandemic (P-1) and pandemic (P-2) periods. Molecular diagnostic methods using the cerebrospinal fluid of patients from all age groups were included. The positivity rate difference of the ME-causing pathogens between the two study periods was compared and the distribution pattern of the pathogens among the age groups was determined. Results: The overall positivity rate for at least one ME-causing pathogen during P-1 was 22.0% (503/2,284), which significantly declined to 7.3% (83/1,141) during P-2 (p = 3 years) (p = 3 years, although not uniformly. | Ture, Hirut Y.; Nam, Eon Jeong; Hwang, Soyoon; Kwon, Ki Tae; Lee, Nan Young | Kyungpook Natl Univ, Chilgok Hosp, Dept Internal Med, Div Rheumatol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Rheumatol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Infect Dis,Kyungpook Natl Univ Hosp, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Lab Med, 807 Hoguk ro, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea | Kim, So-Young/JFS-7698-2023 | 58112648500; 7005824293; 57203160675; 9733850500; 57209204358 | leenanyoung70@gmail.com; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 70 | 9 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2024 | 0.6 | 92.4 | 0 | 2025-05-07 | 0 | 0 | meningoencephalitis; pathogens; COVID-19; enterovirus | CEREBROSPINAL-FLUID; ENTEROVIRAL MENINGITIS; DISEASE; COINFECTION; SURVEILLANCE; INFECTION; INFLUENZA; ZHENGZHOU; CHILDREN; BENEFIT | COVID-19; enterovirus; meningoencephalitis; pathogens | Adolescent; Adult; Aged; Aged, 80 and over; Child; Child, Preschool; COVID-19; Female; Humans; Infant; Infant, Newborn; Male; Meningoencephalitis; Middle Aged; Pandemics; Retrospective Studies; SARS-CoV-2; Young Adult; adolescent; adult; age distribution; Article; bacterial meningoencephalitis; bacterium detection; cerebrospinal fluid analysis; child; coinfection; controlled study; coronavirus disease 2019; cryptococcal meningoencephalitis; Cryptococcus gattii; Cryptococcus neoformans; cytomegalovirus encephalitis; DNA extraction; Enterovirus; enterovirus meningoencephalitis; epidemic meningitis; Escherichia coli; Escherichia coli meningitis; female; group B streptococcal meningitis; Haemophilus influenzae; Haemophilus meningitis; herpes simplex meningoencephalitis; Herpes simplex virus 2; herpes zoster encephalitis; human; Human alphaherpesvirus 1; Human herpesvirus 6; human herpesvirus 6 encephalitis; Human parechovirus; incidence; infant; infectious agent; lifestyle modification; Listeria meningoencephalitis; Listeria monocytogenes; major clinical study; male; molecular diagnosis; multiplex polymerase chain reaction; Neisseria meningitidis; newborn; nonhuman; pandemic; parechovirus infection; pneumococcal meningitis; positivity rate; preschool child; retrospective study; species distribution; Streptococcus agalactiae; Streptococcus pneumoniae; Varicella zoster virus; viral meningoencephalitis; virus detection; aged; cerebrospinal fluid; diagnosis; epidemiology; isolation and purification; meningoencephalitis; middle aged; pandemic; Severe acute respiratory syndrome coronavirus 2; very elderly; virology; young adult | English | 2024 | 2024 | 10.7754/clin.lab.2024.240324 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Monoclonal Gammopathy in Patients with Neuropathy | Background: The incidence of monoclonal gammopathy of undetermined significance (MGUS) in the population of over 50-year-olds is approximately 3% and increases with age. The association between MG and neuropathy has been of interest for several years, but the causal relationship has not yet been clarified. Methods: For 682 patients who visited the Department of Neurology and requested tests for MG work-up, we retrospectively collected demographic and clinical information, such as age, gender, diagnosis, and neurologic and laboratory test results, from their medical records. Results: Out of a total of 682 patients who were suspected of neuropathy and tested for monoclonal gammopathy (MG), twelve (1.76%) showed MG on their serum protein electrophoresis. The most common form was IgM-kappa with five patients, followed by IgG-kappa, IgG-lambda, and biclonal IgG-lambda and IgA-kappa. The results of the immunoglobulin quantitation test and free light chain assay showed that involved M-protein values in these patients were increased. Some patients were positive for anti-myelin-associated glycoprotein (MAG) antibody, anti-GD1b IgM antibody, anti-GM1 IgG & IgM antibody, and anti-cardiolipin IgM antibody. Also, some had antinuclear antibody (ANA) or antineutrophil cytoplasmic antibody (ANCA). Conclusions: In the future, it is necessary to investigate the pathogenic relationship between M-protein and auto- antibodies in patients with neuropathies. | Ham, Ji Yeon; Lee, Jae Hee; Lee, Nan Young; Song, Kyung Eun | Kyungpook Natl Univ, Chilgok Hosp, Dept Lab Med, Hogukro 804, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea | 59409597100; 57226163939; 57209204358; 57843936100 | kesong@knu.ac.kr; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 70 | 11 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2024 | 0.6 | 92.4 | 0 | 2025-05-07 | 0 | 0 | monoclonal gammopathy; neuropathy; monoclonal gammopathy of undetermined significance; multiple myeloma | UNDETERMINED SIGNIFICANCE; PERIPHERAL NEUROPATHY; MULTIPLE-MYELOMA; PREVALENCE; POLYNEUROPATHY; AUTOANTIBODIES; SERUM; MGUS | monoclonal gammopathy; monoclonal gammopathy of undetermined significance; multiple myeloma; neuropathy | Adult; Aged; Aged, 80 and over; Female; Humans; Immunoglobulin G; Immunoglobulin M; Male; Middle Aged; Monoclonal Gammopathy of Undetermined Significance; Paraproteinemias; Peripheral Nervous System Diseases; Retrospective Studies; antinuclear antibody; cardiolipin antibody; ganglioside GD 1b; ganglioside GM1 antibody; immunoglobulin A; immunoglobulin G; immunoglobulin G antibody; immunoglobulin heavy chain; immunoglobulin kappa chain; immunoglobulin light chain; immunoglobulin M; immunoglobulin M antibody; M protein; myelin associated glycoprotein; myelin oligodendrocyte glycoprotein; neutrophil cytoplasmic antibody; plasma protein; protein antibody; immunoglobulin G; immunoglobulin M; adult; aged; amyotrophic lateral sclerosis; Article; brachial plexus neuropathy; brain infarction; chronic inflammatory demyelinating polyneuropathy; female; Guillain Barre syndrome; human; incidence; major clinical study; male; medical record review; middle aged; monoclonal immunoglobulinemia; motor neuron disease; neuropathy; POEMS syndrome; polyneuropathy; protein electrophoresis; retrospective study; blood; complication; diagnosis; epidemiology; etiology; immunology; monoclonal gammopathy of undetermined significance; paraproteinemia; peripheral neuropathy; very elderly | English | 2024 | 2024 | 10.7754/clin.lab.2024.240522 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sex-specific impacts of obesity on long-term prognosis of traumatic brain injury: a multicenter prospective study | Our investigation delves into the nuanced interplay between obesity and sex on the longterm outcomes of traumatic brain injury (TBI), a relationship that previous studies have hinted at but not thoroughly elucidated. Acknowledging the divergent recovery paths of males and females post-TBI, we aimed to elucidate whether obesity's prognostic impact on TBI prognosis is indeed sex -dependent. This study was a prospective multi -center cohort study conducted on adult TBI patients, with intracranial hemorrhage or diffuse axonal injury confirmed by radiological examination, admitted to five participating emergency departments (EDs) from December 2018 to March 2023. The study outcomes were 6 -month disability and mortality. The primary exposure was obesity, defined as body mass index (BMI) over 25. Multi -level logistic regression analysis was performed to estimate the association between obesity and the study outcomes. We conducted a stratified analysis by sex to investigate whether the association between obesity and TBI outcomes differs between sex. Our multilevel logistic regression analysis, using the normal weight group as a reference, indicated that higher BMI categories over 25 did not significantly alter the risk of 6 -month disability or mortality when compared to the normal weight group. Our study revealed a higher one -month disability rate in female TBI patients with a BMI over 30 compared to those with a normal BMI, highlighting the need for gender -specific approaches in managing and rehabilitating TBI outcomes. | Jung, Eujene; Ryu, Hyun Ho; Park, Gwan Jin; Yoon, Hanna; Lee, Stephen Gyung Won; Moon, Sung Bae; Ro, Young Sun; Do Shin, Sang | Chonnam Natl Univ Hosp, Dept Emergency Med, Gwangju 61469, South Korea; Chonnam Natl Univ, Dept Med, Gwangju 61469, South Korea; Chungbuk Natl Univ Hosp, Dept Emergency Med, Cheongju 28644, South Korea; Seoul Natl Univ Hosp, Dept Emergency Med, Seoul 03080, South Korea; Seoul Natl Univ, Boramae Med Ctr, Dept Emergency Med, Seoul 07061, South Korea; Kyungpook Natl Univ, Dept emergency Med, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Daegu 41944, South Korea; Seoul Natl Univ, Dept Med, Seoul 03080, South Korea | Do Shin, Sang/D-6020-2012 | 57194543281; 26325849500; 57193389046; 57218530108; 58743057200; 57191584601; 37665990400; 57049712400 | em00027@cnuh.ac.kr; | JOURNAL OF MENS HEALTH | J MENS HEALTH | 1875-6867 | 1875-6859 | 20 | 3 | SCIE;SSCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2024 | 0.6 | 92.5 | 0 | 2025-05-07 | 0 | 0 | Sex; Obesity; TBI | HEALTH; EPIDEMIOLOGY; DISABILITY; CARE; TBI | Obesity; Sex; TBI | adult; aged; alcohol consumption; Article; body mass; brain hemorrhage; clinical outcome; cohort analysis; controlled study; demographics; diffuse axonal injury; disability; female; hospital admission; hospitalization; human; incidence; major clinical study; male; mortality rate; obese patient; obesity; prognosis; prospective study; radiodiagnosis; risk assessment; sex difference; traumatic brain injury | English | 2024 | 2024-03 | 10.22514/jomh.2024.042 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Application of Machine-Learning for Detecting Gas Indicator Distribution from Seismic Data | The bright spot and seismic chimney, which are prominent gas indicators observed in seismic data, exhibit distinct geophysical features such as high amplitude, phase reversal, low continuity, and frequency attenuation. As a result, seismic attribute analysis has been widely applied to derive gas distributions within subsurface media. However, seismic attribute analysis has limitation that it is difficult to clearly distinguish gas indicators from other strata with similar geophysical properties. Therefore, this study proposes a machine-learning method to predict the distribution of bright spot and seismic chimney within seismic data. To effectively predict gas indicators in complex seismic data, the study constructed training data by simultaneously using noise-reduced seismic data and various seismic attribute analysis results. The proposed method was applied to 3D seismic survey data acquired from the F3-block in the North Sea, Netherlands to verify the effectiveness of the proposed method. The gas indicator distribution predicted by the trained model demonstrated higher accuracy and consistency compared to traditional multi-seismic attribute analysis results. Additionally, sensitivity analysis and a forward selection method were applied to optimize the selection of input data, confirming that the prediction accuracy was improved when input with low sensitivity was removed. | Won, Jongpil; Jun, Hyunggu | Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea | 58896243400; 56048061400 | hgjun@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 57 | 6 | ESCI | GEOLOGY | 2024 | 0.3 | 92.6 | 0 | 2025-05-07 | 0 | 0 | seismic attribute analysis; machine learning; gas distribution; gas indicator; confusion matrix | ARTIFICIAL NEURAL-NETWORK; RANDOM NOISE ATTENUATION; TARANAKI BASIN; 3D PROSPECT; CHIMNEY; MULTIATTRIBUTE; ATTRIBUTES | confusion matrix; gas distribution; gas indicator; machine learning; seismic attribute analysis | English | 2024 | 2024-12 | 10.9719/eeg.2024.57.6.681 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Applying Transfer Learning to Improve the Performance of Deep Learning-based Groundwater Level Prediction Model with Insufficient Training Data | Predicting groundwater levels with data-driven models like artificial neural networks typically requires a substantial amount of data. However, when groundwater monitoring wells are newly developed or when a significant portion of the data is invalid (for example, due to missing values or outliers), acquiring an adequate dataset for training prediction models becomes challenging, leading to diminished prediction accuracy. This study proposes a method based on transfer learning to address the issue of insufficient training data. The Gated Recurrent Unit (GRU) was used as the primary data-driven model for predictions. A GRU-based pretrained network for the transfer learning process was developed using groundwater level and corresponding rainfall data collected from 89 monitoring stations nationwide. Subsequently, this pretrained network was fine-tuned using a small amount of training data obtained from the target monitoring well to develop the final prediction model. To verify the effectiveness of the transfer learning algorithm, two different groundwater level prediction models were evaluated: 1) a GRU-based model trained with insufficient data from the target well, and 2) a GRU-based model utilizing the transfer learning algorithm. Comparative verification was conducted with groundwater level data obtained from wells at two different locations, where the model using the transfer learning algorithm demonstrated superior performance compared to the other. This study confirms that the transfer learning algorithm can significantly enhance the performance of groundwater level prediction models, irrespective of the amount of available training data. | Jeong, Jiho; Jeong, Jina | Kyungpook Natl Univ, Dept Geol, Daegu, South Korea | 57218684286; 55488558800 | jeong.j@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 57 | 5 | ESCI | GEOLOGY | 2024 | 0.3 | 92.6 | 0 | 2025-05-07 | 1 | 1 | groundwater level prediction; precipitation; gated recurrent unit; training data deficiency problem; transfer learning | ARTIFICIAL NEURAL-NETWORKS; FUZZY INFERENCE SYSTEM; WATER-TABLE DEPTH; SUPPORT VECTOR MACHINES; WAVELET; ANN | gated recurrent unit; groundwater level prediction; precipitation; training data deficiency problem; transfer learning | Korean | 2024 | 2024-10 | 10.9719/eeg.2024.57.5.551 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Evaluation of Hydrogeological Characteristic of Natural Barrier in Korea for Establishing Safety Guidelines of Deep Geological High-Level Radioactive Waste Disposal Site | This study assessed the hydrogeological properties of the deep geological environment to develop safety criteria for the natural barriers used in the deep geological disposal of high-level radioactive waste in Korea. The assessment focused on the distribution and trends of hydraulic conductivity and permeability properties appropriate for the domestic geological environment, using various in-situ hydraulic test data collected for groundwater development and management. To develop a depth-hydrogeological property relationship model suitable for domestic conditions, the study reviewed various international research examples and applied a representative model that explains the trends of hydraulic conductivity and permeability with depth. The development of the model suitable for Korea involved applying ensemble regression analysis to account for the uncertainty of various factors in the collected data. The results confirmed that existing international depthhydrogeological property relationship models adequately describe the characteristics of the domestic geological environment. Considering the preferred hydrogeological criteria suggested by countries like Sweden, Germany, and Canada, there is a high likelihood that a suitable geological environment exists in Korea. Additionally, the application of hydrogeological criteria indicative of low-permeability environments showed that suitable conditions for disposal construction increase at depths greater than 300 m, where the influence of fractures on groundwater flow might be minimal at depths exceeding 500 m.

The Taehwa River flows through the major industrial city of Ulsan and eventually into the sea, where it is impacted by both anthropogenic pollution and natural processes such as rock weathering. In the upstream region, the weathering of igneous and sedimentary rocks plays a dominant role, resulting in high ratios of ions such as Ca, Mg, and HCO3. Additionally, the weathering of igneous rocks in the upper reaches contributes to elevated Si ratio. However, as the river flows downstream, the ratios of Cl and SO4 ions increase greatly due to human activities, such as the discharge of industrial effluents, domestic wastewater, and agricultural runoff. In the downstream areas, the mixing of seawater causes a significant rise in Na and Cl ratios, indicating the influence of seawater on the river water. Regarding heavy metals, their concentrations generally increase from upstream to downstream. Zn and As, in particular, show relatively high levels due to nearby industrial activities and abandoned mines, while other heavy metals exhibit irregular variations depending on the location. This study identifies the spatial distribution and origins of major ions and heavy metals in the Taehwa River, providing fundamental data for understanding how rivers respond to natural weathering and human activities. | Jo, Duk-Hee; Kim, Yeongkyoo | Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea | 57221747260; 7410207179 | ygkim@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 57 | 6 | ESCI | GEOLOGY | 2024 | 0.3 | 92.6 | 0 | 2025-05-07 | 0 | 0 | the Taehwa River; weathering; human activity; pollution; heavy metal | MAJOR-ELEMENT CHEMISTRY; HAN RIVER; DISSOLVED SULFATE; ION CHEMISTRY; AMAZON; BASIN; IDENTIFICATION; SYSTEM; CHINA; KOREA | heavy metal; human activity; pollution; the Taehwa River; weathering | Korean | 2024 | 2024-12 | 10.9719/eeg.2024.57.6.811 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structural Geometry of a Regional-scale Overturned Fold in the Daecheong Island, Central-western Korean Peninsula | This study reports the structural geometry and folding mechanism of a regional-scale overturned fold in the Daecheong Island, centralwestern part of the Korean Peninsula. Based on low-hemisphere stereographic and down-plunge projections using data from a detailed field survey, we classify the regional-scale fold as an open overturned fold shallowly plunging toward NE. The asymmetric and symmetric parasitic folds in the limb and hinge zones indicate layer-parallel shortening prior to flexural-flow folding. Fold dating must be required to decipher the orogenic process causing the regional-scale overturned fold in the Daecheong Island. | Park, Jeong-Yeong; Cho, Deung-Lyong; Lee, Seung Hwan; Kwak, Yujung; Park, Seung-Ik | Korea Inst Geosci & Mineral Resources, Geol & Space Res Div, Daejeon 34132, South Korea; Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea | 58947446100; 58947778500; 58947364900; 58947778600; 58947695900 | psi@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 57 | 1 | ESCI | GEOLOGY | 2024 | 0.3 | 92.6 | 0 | 2025-05-07 | 0 | 0 | Daecheong Island; orogenic process; overturned fold; parasitic fold; flexural-flow | U-PB AGES; SOUTH-KOREA; TECTONIC EVOLUTION; HONGSEONG AREA; BELT; OROGENY; NORTH | Daecheong Island; flexural-flow; orogenic process; overturned fold; parasitic fold | English | 2024 | 2024-02 | 10.9719/eeg.2024.57.1.41 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Study on the Seismic Random Noise Attenuation for the Seismic Attribute Analysis | Seismic exploration is one of the widely used geophysical exploration methods with various applications such as resource development, geotechnical investigation, and subsurface monitoring. It is essential for interpreting the geological characteristics of subsurface by providing accurate images of stratum structures. Typically, geological features are interpreted by visually analyzing seismic sections. However, recently, quantitative analysis of seismic data has been extensively researched to accurately extract and interpret target geological features. Seismic attribute analysis can provide quantitative information for geological interpretation based on seismic data. Therefore, it is widely used in various fields, including the analysis of oil and gas reservoirs, investigation of fault and fracture, and assessment of shallow gas distributions. However, seismic attribute analysis is sensitive to noise within the seismic data, thus additional noise attenuation is required to enhance the accuracy of the seismic attribute analysis. In this study, four kinds of seismic noise attenuation methods are applied and compared to mitigate random noise of poststack seismic data and enhance the attribute analysis results. FX deconvolution, DSMF, Noise2Noise, and DnCNN are applied to the Youngil Bay high-resolution seismic data to remove seismic random noise. Energy, sweetness, and similarity attributes are calculated from noise-removed seismic data. Subsequently, the characteristics of each noise attenuation method, noise removal results, and seismic attribute analysis results are qualitatively and quantitatively analyzed. Based on the advantages and disadvantages of each noise attenuation method and the characteristics of each seismic attribute analysis, we propose a suitable noise attenuation method to improve the result of seismic attribute analysis. | Won, Jongpil; Shin, Jungkyun; Ha, Jiho; Jun, Hyunggu | Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources KIGAM, Pohang Branch, Pohang 37559, South Korea | Shin, Jungkyun/JXN-1707-2024; Jun, Hyunggu/ABT-7172-2022 | 58947778000; 58947445700; 58947778100; 56048061400 | hgjun@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 57 | 1 | ESCI | GEOLOGY | 2024 | 0.3 | 92.6 | 1.1 | 2025-05-07 | 2 | 2 | seismic attribute analysis; noise attenuation; machine learning; gas distribution; seismic data | ARTIFICIAL NEURAL-NETWORK; FIELD DEVELOPMENT; TARANAKI BASIN; 3D PROSPECT; SHALLOW GAS; WELL-LOG; CHANNEL; FAULTS; MULTIATTRIBUTE; IDENTIFICATION | gas distribution; machine learning; noise attenuation; seismic attribute analysis; seismic data | English | 2024 | 2024-02 | 10.9719/eeg.2024.57.1.51 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | DEVELOPMENT AND VALIDATION OF A RELATIVE BLOOD FLOW CHANGE MEASUREMENT ALGORITHM USING NEAR-INFRARED LIGHT | The purpose of this study is to develop a near-infrared blood flow measurement algorithm and verify its performance. The gradient value of the measurement point was determined by using LED lights with wavelengths of 760nm and 850nm. This process involved measuring the gradient value for a significant number of regularly spaced cubic pixels centered around the chosen point. The measured gradient values for each pixel were then averaged to derive the final gradient value. Based on the measurement of the gradation value, when the concentration ratio of blood was altered by 20% between 0% and 100%, the gradation values at 760nm and 850nm changed significantly (more than +/- 2.5%) in all cases. This study validated the efficacy of a self-developed near-infrared light system for detecting changes in blood flow. The ability to measure alterations in blood flow can be instrumental in predicting peripheral vascular disease (PVD) due to compromised circulatory conditions. | Park, Jieun; Kim, Junghun; Choi, Sang-il; Lee, Jongmin | Kyungpook Natl Univ & Hosp Daegu, Biomed Res Inst, Daegu 41940, South Korea; Daegu Catholic Univ, Sch Comp Software, Gyongsan 38430, Gyeongbuk, South Korea; Kyungpook Natl Univ & Hosp, Dept Radiol, Sch Med, Daegu 41948, South Korea | ; Choi, Sangil/N-7571-2013; Lee, Jongmin/AAR-6361-2020 | 57209642201; 58567949800; 57222086807; 55689919700 | geraniumnn@naver.com;fainal2@naver.com;sangilchoi@cu.ac.kr;jonglee@knu.ac.kr; | JOURNAL OF MECHANICS IN MEDICINE AND BIOLOGY | J MECH MED BIOL | 0219-5194 | 1793-6810 | 24 | 08 | SCIE | BIOPHYSICS;ENGINEERING, BIOMEDICAL | 2024 | 0.6 | 93.1 | 0 | 2025-05-07 | 0 | 0 | Peripheral vascular disease; near-infrared blood flow measurement algorithm; ischemia; diagnostic methods | PERIPHERAL ARTERIAL-DISEASE; DIAGNOSIS | diagnostic methods; ischemia; near-infrared blood flow measurement algorithm; Peripheral vascular disease | Flow measurement; Flowmeters; Blood flow; Blood flow measurement; Diagnostic methods; Ischaemia; Measurement algorithms; Near Infrared; Near infrared light; Near-infrared; Near-infrared blood flow measurement algorithm; Peripheral vascular disease; Infrared devices | English | 2024 | 2024-10 | 10.1142/s0219519424400335 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | The Impact of Multinationals' Home-Returning Threats on the Fiscal Policies of Host Countries | Multinational firms use the threat of returning to their home country to gain leverage over host governments, often securing excessive subsidies or tax reductions. This study examines how such "home-returning threats" influence host governments' decisions to provide financial support, revealing that governments tend to offer unnecessary incentives to retain these firms. The research highlights that firms benefit more from continuing production abroad, using the threat as a negotiation tool to maximize profits, while host countries bear the cost of excessive subsidies. | Kwon, Chul-Woo; Hwang, Uk | Kyungpook Natl Univ, Dept Econ, 80 Daehak Ro, Daegu 41566, South Korea | 26023382500; 53866824100 | cwkwon@knu.ac.kr;uh202@knu.ac.kr; | JOURNAL OF INSTITUTIONAL AND THEORETICAL ECONOMICS-ZEITSCHRIFT FUR DIE GESAMTE STAATSWISSENSCHAFT | J INST THEOR ECON | 0932-4569 | 1614-0559 | 180 | 4 | SSCI | ECONOMICS | 2024 | 0.2 | 93.1 | 0 | 2025-05-07 | 0 | 0 | multinationals; home-returning threat; offshoring; reshoring; tax policies | UNIONIZATION; INVESTMENT | home-returning threat; multinationals; offshoring; reshoring; tax policies | English | 2024 | 2024 | 10.1628/jite-2024-0034 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
