| ○ | ○ | Article | The characteristics of cognitive and daily living functions of neurocognitive disorders with delusions in elderly Alzheimer's disease | Background. . Delusions in neurocognitive disorder due to Alzheimer's disease (AD) worsen patients' cognitive functions and activities of daily living (ADL), increasing caregiver burden and the risk of mortality. AD patients with delusions tend to experience a more rapid decline in cognition and have demonstrated poorer performance on various cognitive function tests. Considering the prognosis of delusion in AD patients, it tends to be more favorable with appropriate treatment. However, there is a lack of neuropsychological research, specifically examining the impact of delusions in AD, characterized by progressive deterioration of cognitive function. This study investigates the impact of delusions on cognitive function and ADL under conditions controlling for disease severity. Methods. . We compared cognitive function and ADL in AD patients aged 65 years or older according to the presence of delusions. To assess longitudinal change, we analyzed data from patients monitored for an average of 15 to 16 months. We assessed cognitive function and ADL using the Seoul Neuropsychological Screening Battery- Second Edition (SNSB-II) and delusions using the Neuropsychiatric Inventory (NPI). We used IBM SPSS Statistics version 25.0 for all statistical analyses. The analysis was not adjusted for multiple comparisons. We investigated how delusions impact cognitive function and ADL, controlling for age, educational level, and disease severity. Results. . The delusions group exhibited poorer immediate recall of verbal memory than the non-delusions group. In the follow-up evaluation, patients who developed delusions had lower baseline cognitive function than those who did not, and their language fluency declined over time. In addition, we found the presence of delusions associated with worse functional impairment in ADL as the disease progressed. Conclusion. . While controlling for the severity of AD, we found no significant negative impacts of delusions on most cognitive functions. Nevertheless, it is noteworthy that the immediate recall of verbal memory and the Controlled Oral Word Association Test (COWAT)ₐₙᵢₘₐₗ sensitively detected the negative impact of delusions. Furthermore, since delusions are associated with worsening ADL, we understand that delusion treatment is important for improving the quality of life for patients and caregivers. | Kim, Seo Yoo; Lee, Soo Jin | Kyungpook Natl Univ, Dept Psychol, Daegu, South Korea; Good Samsun Hosp, Dept Neuropsychiat, Pusan, South Korea; Kyungsung Univ, Dept Psychol, Pusan, South Korea | 59340847900; 57605727400 | leesooj@gmail.com; | PEERJ | PEERJ | 2167-8359 | 12 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.4 | 34.4 | 0 | 2025-05-07 | 0 | 0 | Alzheimer's disease; Cognitive functions; Daily living functions; Delusions; Neurocognitive disorder | NEUROPSYCHIATRIC SYMPTOMS; PSYCHOTIC SYMPTOMS; VERBAL FLUENCY; RISK-FACTORS; DEMENTIA; IMPAIRMENT; INVENTORY; PREVALENCE; MEMORY; LIFE | Alzheimer's disease; Cognitive functions; Daily living functions; Delusions; Neurocognitive disorder | aged; aggression; agitation; Alzheimer disease; anxiety; Article; Barthel Activities of Daily Living; cognition; controlled oral word association test; daily life activity; delusion; depression; disorders of higher cerebral function; dysphoria; euphoria; female; follow up; hallucination; human; Korean-Color Word Stroop Test; Korean-Instrumental Activities of Daily Living; major clinical study; male; neuropsychological assessment; retrospective study; Seoul Neuropsychological Screening Battery-Second Edition; Seoul Verbal Learning Test; Short form of the Korean-Boston Naming Test | English | 2024 | 2024-09-13 | 10.7717/peerj.18026 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Revision of the Phylogeny of Helicotylenchus Steiner, 1945 (Tylenchida: Hoplolaimidae) as Inferred from Ribosomal and Mitochondrial DNA | Identification of Helicotylenchus species is very challenging due to phenotypic plasticity and existence of cryptic species complexes. Recently, the use of rDNA barcodes has proven to be useful for identification of Helicotylenchus. Molecular markers are a quick diagnostic tool and are crucial for discriminating related species and resolving cryptic species complexes within this speciose genus. However, DNA barcoding is not an error -free approach. The public databases appear to be marred by incorrect sequences, arising from sequencing errors, mislabeling, and misidentifications. Herein, we provide a comprehensive analysis of the newly obtained, and published DNA sequences of Helicotylenchus, revealing the potential faults in the available DNA barcodes. A total of 97 sequences (25 nearly full-length 18S-rRNA, 12 partial 28S-rRNA, 16 partial internal transcribed spacer [ITS]-rRNA, and 44 partial cytochrome c oxidase subunit I [COI] gene sequences) were newly obtained in the present study. Phylogenetic relationships between species are given as inferred from the analyses of 103 sequences of 18S-rRNA, 469 sequences of 28S-rRNA, 183 sequences of ITS-rRNA, and 63 sequences of COI. Remarks on suggested corrections of published accessions in GenBank database are given. Additionally, COI gene sequences of H. dihystera, H. asiaticus and the contentious H. microlobus are provided herein for the first time. Similar to rDNA gene analyses, the COI sequences support the genetic distinctness and validity of H. microlobus. DNA barcodes from type material are needed for resolving the taxonomic status of the unresolved taxonomic groups within the genus. | Mwamula, Abraham Okki; Kwon, Oh-Gyeong; Kwon, Chanki; Kim, Yi Seul; Kim, Young Ho; Lee, Dong Woon | Kyungpook Natl Univ, Res Inst Invertebrate Vector, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Ecol Sci, Sangju 37224, South Korea; Kyungpook Natl Univ, Grad Sch Plant Protect & Quarantine, Dept Plant Protect & Quarantine, Daegu 41566, South Korea | 56786549100; 57204759255; 59000677700; 57204608381; 58516491300; 7406669991 | whitegrub@knu.ac.kr; | PLANT PATHOLOGY JOURNAL | PLANT PATHOLOGY J | 1598-2254 | 2093-9280 | 40 | 2 | SCIE | PLANT SCIENCES | 2024 | 2.5 | 34.6 | 0.53 | 2025-05-07 | 2 | 1 | Bayesian inference; DNA barcodes; Helicotylenchus microlobus; phylogenetic relationships; species identification | PLANT-PARASITIC NEMATODES; D2-D3 EXPANSION SEGMENTS; FRAGMENT-LENGTH-POLYMORPHISM; GENUS PRATYLENCHUS NEMATODA; MOLECULAR CHARACTERIZATION; PSEUDOROBUSTUS STEINER; SPIRAL NEMATODES; 1914 GOLDEN; N-SP; IDENTIFICATION | Bayesian inference; DNA barcodes; Helicotylenchus microlobus; phylogenetic relationships; species identification | English | 2024 | 2024-04 | 10.5423/ppj.oa.01.2024.0013 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Clinical and Genetic Characteristics Associated With Survival Outcome in Late-Onset Huntington's Disease in South Korea | Background and Purpose The onset of Huntington's disease (HD) usually occurs before the age of 50 years, and the median survival time from onset is 15 years. We investigated survival in patients with late -onset HD (LoHD) (age at onset >= 60 years) and the associations of the number of mutant CAG repeats and age at onset (AAO) with survival in patients with HD. Methods Patients with genetically confirmed HD at six referral centers in South Korea between 2000 and 2020 were analyzed retrospectively. Baseline demographic, clinical, and genetic characteristics and the survival status as at December 2020 were collected. Results Eighty-seven patients were included, comprising 26 with LoHD (AAO=68.77 +/- 5.91 years, mean +/- standard deviation; 40.54 +/- 1.53 mutant CAG repeats) and 61 with common -onset HD (CoHD) (AAO=44.12 +/- 8.61 years, 44.72 +/- 4.27 mutant CAG repeats). The ages at death were 77.78 +/- 7.46 and 53.72 +/- 10.86 years in patients with LoHD and CoHD, respectively (p< 0.001). The estimated survival time was 15.21 +/- 2.49 years for all HD patients, and 10.74 +/- 1.95 and 16.15 +/- 2.82 years in patients with LoHD and CoHD, respectively. More mutant CAG repeats and higher AAO were associated with shorter survival (hazard ratio [HR]=1.05, 95% confidence interval [CI]=1.01-1.09, p=0.019; and HR=1.17, 95% CI=1.03-1.31, p=0.013; respectively) for all HD patients. The LoHD group showed no significant factors associated with survival after disease onset, whereas the number of mutant CAG repeats had a significant effect (HR=1.12, 95% CI=1.01-1.23, p=0.034) in the CoHD group. Conclusions Survival after disease onset was shorter in patients with LoHD than in those with CoHD. More mutant CAG repeats and higher AAO were associated with shorter survival in patients with HD. | Hwang, Yun Su; Jo, Sungyang; Kim, Gu-Hwan; Lee, Jee-Young; Ryu, Ho-Sung; Oh, Eungseok; Lee, Seung-Hwan; Kim, Young Seo; Chung, Sun Ju | Jeonbuk Natl Univ, Med Sch & Hosp, Dept Neurol, Jeonju, South Korea; Jeonbuk Natl Univ, Biomed Res Inst, Res Inst Clin Med, Jeonbuk Natl Univ Hosp, Jeonju, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Neurol, 88 Olymp Ro 43 Gil, Seoul 05505, South Korea; Univ Ulsan, Coll Med, Med Genet Ctr, Asan Med Ctr, Seoul, South Korea; Seoul Natl Univ, Med Coll, Dept Neurol, Seoul Metropolitan Govt,Boramae Med Ctr, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Neurol, Daegu, South Korea; Chungnam Natl Univ Hosp, Dept Neurol, Daejeon, South Korea; Kangwon Natl Univ Hosp, Dept Neurol, Chunchon, South Korea; Wonkwang Univ, Sch Med, Dept Neurol, Iksan, South Korea | ; Kim, Hyo-Won/M-9932-2019; Lee, SeungHwan/KLD-0757-2024; Oh, Eungseok/AAL-8935-2020 | 57219161130; 57204969008; 7403064317; 57225303444; 57014206500; 55833749700; 56133953700; 57214230759; 56882955600 | sjchung@amc.seoul.kr; | JOURNAL OF CLINICAL NEUROLOGY | J CLIN NEUROL | 1738-6586 | 2005-5013 | 20 | 4 | SCIE | CLINICAL NEUROLOGY | 2024 | 3.1 | 34.6 | 1.25 | 2025-05-07 | 2 | 2 | late-onset Huntington's disease; CAG repeats; survival; lifespan; age at onset | AGE; IMPACT | age at onset; CAG repeats; late-onset Huntington’s disease; lifespan; survival | adult; aged; Alzheimer disease; Article; CAG repeat; cognition; cognitive defect; disease duration; female; follow up; genetic trait; human; human tissue; Huntington chorea; Korean (people); life expectancy; major clinical study; male; median survival time; mental disease; Mini Mental State Examination; onset age; overall survival; patient referral; prevalence; retrospective study; risk factor; South Korea; survival time | English | 2024 | 2024-07 | 10.3988/jcn.2023.0329 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Effect of chewing hard material on boosting brain antioxidant levels and enhancing cognitive function | Introduction Chewing has been reported to enhance cognitive function through the increase in cerebral blood flow. However, the mechanisms linking cerebral blood flow increase to metabolic changes in the brain affecting cognition remain unclear. We hypothesized that glutathione (GSH) plays a pivotal role in these mechanisms. Therefore, this study aimed to investigate changes in brain GSH levels following chewing and their association with cognitive function in healthy young adults.Methods A total of 52 university students were recruited, and the Korean version of the Repeatable Battery for the Assessment of Neuropsychological Status was used for the neurocognitive evaluations. Brain GSH levels following chewing gum or wood blocks were measured using MEscher-GArwood Point RESolved Spectroscopy (MEGA-PRESS) sequence, and their relevance to neurocognitive evaluation results was investigated.Results Chewing significantly increased brain GSH concentration, particularly in the wood-chewing group compared to the gum-chewing group, as observed in the anterior cingulate cortex. Furthermore, the rise in GSH concentration in the wood-chewing group was positively correlated with memory function.Conclusion Chewing moderately hard material elevates brain antioxidant levels such as GSH, potentially influencing cognitive function. | Kim, Seungho; Kim, Ji-Hye; Lee, Hansol; Jang, Sung Ho; Noeske, Ralph; Choi, Changho; Chang, Yongmin; Choi, Youn-Hee | Kyungpook Natl Univ, Dept Med & Biol Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prevent Dent, Daegu, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Phys Med & Rehabil, Daegu, South Korea; GE Healthcare, Munich, Germany; Vanderbilt Univ, Med Ctr, Dept Radiol & Radiol Sci, Nashville, TN USA; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu, South Korea | 57218284791; 58099706300; 59299461900; 57207139325; 8666816700; 55070978500; 7501840633; 7404777239 | cyh1001@knu.ac.kr;ychang@knu.ac.kr; | FRONTIERS IN SYSTEMS NEUROSCIENCE | FRONT SYST NEUROSCI | 1662-5137 | 18 | SCIE | NEUROSCIENCES | 2024 | 3.5 | 34.6 | 0 | 2025-05-07 | 2 | 2 | mastication; hardness; functional magnetic resonance imaging (fMRI); cognitive function; motor function; brain activation | MAGNETIC-RESONANCE-SPECTROSCOPY; IN-VIVO; OXIDATIVE STRESS; MR SPECTROSCOPY; GLUTATHIONE LEVELS; QUANTIFICATION; INTENSITY; DISORDER; DAMAGE; ROLES | brain activation; cognitive function; functional magnetic resonance imaging (fMRI); hardness; mastication; motor function | antioxidant; chewing hard material; dental material; glutathione; unclassified drug; anterior cingulate; Article; brain antioxidant level; brain blood flow; chewing gum; cognition; cognitive defect; enamel; enamel hardness; executive function; female; functional magnetic resonance imaging; gray matter; head movement; human; human experiment; male; mastication; neuropsychological assessment; normal human; nuclear magnetic resonance imaging; physical activity; questionnaire; temporomandibular joint; trail making test; white matter | English | 2024 | 2024-11-27 | 10.3389/fnsys.2024.1489919 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Persistent differences in the immunogenicity of the two COVID-19 primary vaccines series, modulated by booster mRNA vaccination and breakthrough infection | Introduction: The long-term impact of initial immunogenicity induced by different primary COVID-19 vaccine series remains unclear. Methods: A prospective cohort study was conducted at 10 tertiary hospitals in Korea from March 2021 to September 2022. Immunogenicity assessments included anti-spike protein antibody (Sab), SARS-CoV-2-specific interferon-gamma releasing assay (IGRA), and multiplex cytokine assays for spike protein-stimulated plasma. Spike proteins derived from wild-type SARS-CoV-2 and alpha variant (Spike(1)) and beta and gamma variant (Spike(2)) were utilized. Results: A total of 235 healthcare workers who had received a two-dose primary vaccine series of either ChAdOx1 or BNT162b2, followed by a third booster dose of BNT162b2 (166 in the ChAdOx1/ChAdOx1/BNT162b2 (CCB) group and 69 in the BNT162b2/BNT162b2/BNT162b2 (BBB) group, based on the vaccine series) were included. Following the primary vaccine series, the BBB group exhibited significantly higher increases in Sab levels, IGRA responses, and multiple cytokines (CCL2/MCP-1, CCL3/MIP-1 alpha, CCL4/MIP-1 beta, interleukin (IL)-1ra, IFN-gamma, IL-2, IL-4, and IL-10) compared to the CCB group (all P < 0.05). One month after the third BNT162b2 booster, the CCB group showed Sab levels comparable to those of the BBB group, and both groups exhibited lower levels after six months without breakthrough infections (BIs). However, among those who experienced BA.1/2 BIs after the third booster, Sab levels increased significantly more in the BBB group than in the CCB group (P < 0.001). IGRA responses to both Spike(1) and Spike(2) proteins were significantly stronger in the BBB group than the CCB group after the third booster, while only the Spike(2) response were higher after BIs (P = 0.007). The BBB group exhibited stronger enhancement of T-cell cytokines (IL-2, IL-4, and IL-17A) after BIs than in the CCB group (P < 0.05). Conclusion: Differences in immunogenicity induced by the two primary vaccine series persisted, modulated by subsequent booster vaccinations and BIs. | Lee, Keon Young; Song, Kyoung-Ho; Lee, Kyoung Hwa; Baek, Jin Yang; Kim, Eu Suk; Song, Young Goo; Kim, Yong Chan; Park, Yoon Soo; Ahn, Jin Young; Choi, Jun Yong; Choi, Won Suk; Bae, Seongman; Kim, Shin-Woo; Kwon, Ki Tae; Kang, Eun-Suk; Peck, Kyong Ran; Kim, Sung-Han; Jeong, Hye Won; Ko, Jae-Hoon | Sungkyunkwan Univ, Sch Med, Div Infect Dis, Samsung Med Ctr, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Coll Med, Seongnam, South Korea; Yonsei Univ, Coll Med, Gangnam Severance Hosp, Div Infect Dis,Dept Internal Med, Seoul, South Korea; Asia Pacific Fdn Infect Dis APFID, Seoul, South Korea; Yonsei Univ, Yongin Severance Hosp, Dept Internal Med, Div Infect Dis,Coll Med, Yongin, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Internal Med, Seoul, South Korea; Korea Univ, Coll Med, Dept Internal Med, Div Infect Dis,Ansan Hosp, Ansan, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Infect Dis, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Infect Dis,Kyungpook Natl Univ Hosp, Daegu, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Lab Med & Genet, Sch Med, Seoul, South Korea; Chungbuk Natl Univ, Coll Med, Dept Internal Med, Cheongju, South Korea | Park, Yoon/C-6472-2015; Hwang, Soyoon/HHM-5762-2022; Choi, Jun/AEH-4018-2022; Lee, Kyoung-Hwa/AAJ-5213-2021; Choi, Won Suk/V-2730-2017; Baek, Jin Yang/JXO-3331-2024; Peck, Kyong Ran/AGV-5205-2022; Choi, Won/V-2730-2017; Jeong, Hye/AET-1982-2022; Kim, Eu/J-5424-2012 | 58479149200; 23398486700; 56955948100; 8926034300; 22938086900; 55675198500; 36486497700; 7405373036; 57225850337; 57791298700; 56718971800; 57189690904; 8710731500; 9733850500; 20234715300; 55664295200; 55133790400; 13103042700; 55804188300 | shkimmd@amc.seoul.kr;hwjeong@chungbuk.ac.kr;jaehoon.ko@samsung.com; | VACCINE | VACCINE | 0264-410X | 1873-2518 | 42 | 19 | SCIE | IMMUNOLOGY;MEDICINE, RESEARCH & EXPERIMENTAL | 2024 | 3.5 | 34.6 | 1.66 | 2025-05-07 | 2 | 3 | COVID-19; SARS-CoV-2; Vaccine; Interferon-gamma releasing assay; Cytokine; Breakthrough infection | Breakthrough infection; COVID-19; Cytokine; Interferon-gamma releasing assay; SARS-CoV-2; Vaccine | Adult; Antibodies, Viral; BNT162 Vaccine; Breakthrough Infections; ChAdOx1 nCoV-19; COVID-19; COVID-19 breakthrough infections; COVID-19 Vaccines; Cytokines; Female; Health Personnel; Humans; Immunization, Secondary; Immunogenicity, Vaccine; Male; Middle Aged; Prospective Studies; Republic of Korea; SARS-CoV-2; SARS-CoV-2 variants; Spike Glycoprotein, Coronavirus; Vaccination; coronavirus spike glycoprotein; gamma interferon; interleukin 1 receptor blocking agent; interleukin 17; interleukin 2; interleukin 4; macrophage inflammatory protein 1alpha; monocyte chemotactic protein 1; protein antibody; SARS-CoV-2 vaccine; tozinameran; vaxzevria; bnt 162 vaccine; coronavirus spike glycoprotein; cytokine; SARS-CoV-2 vaccine; spike protein, SARS-CoV-2; vaxzevria; virus antibody; adult; Article; blood brain barrier; body mass; breakthrough infection; cellular immunity; cohort analysis; coronavirus disease 2019; female; human; human experiment; immune response; interferon gamma release assay; male; prospective study; Severe acute respiratory syndrome coronavirus 2; tertiary care center; vaccination; vaccine immunogenicity; blood; breakthrough infection; coronavirus disease 2019; health care personnel; immunology; middle aged; prevention and control; procedures; secondary immunization; Severe acute respiratory syndrome coronavirus 2; South Korea; vaccination; vaccine immunogenicity | English | 2024 | 2024-07-25 | 10.1016/j.vaccine.2024.05.003 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Prediction of longitudinal clinical outcomes after acute myocardial infarction using a dynamic machine learning algorithm | Several regression-based models for predicting outcomes after acute myocardial infarction (AMI) have been developed. However, prediction models that encompass diverse patient-related factors over time are limited. This study aimed to develop a machine learning-based model to predict longitudinal outcomes after AMI. This study was based on a nationwide prospective registry of AMI in Korea (n = 13,104). Seventy-seven predictor candidates from prehospitalization to 1 year of follow-up were included, and six machine learning approaches were analyzed. Primary outcome was defined as 1-year all-cause death. Secondary outcomes included all-cause deaths, cardiovascular deaths, and major adverse cardiovascular event (MACE) at the 1-year and 3-year follow-ups. Random forest resulted best performance in predicting the primary outcome, exhibiting a 99.6% accuracy along with an area under the receiver-operating characteristic curve of 0.874. Top 10 predictors for the primary outcome included peak troponin-I (variable importance value = 0.048), in-hospital duration (0.047), total cholesterol (0.047), maintenance of antiplatelet at 1 year (0.045), coronary lesion classification (0.043), N-terminal pro-brain natriuretic peptide levels (0.039), body mass index (BMI) (0.037), door-to-balloon time (0.035), vascular approach (0.033), and use of glycoprotein IIb/IIIa inhibitor (0.032). Notably, BMI was identified as one of the most important predictors of major outcomes after AMI. BMI revealed distinct effects on each outcome, highlighting a U-shaped influence on 1-year and 3-year MACE and 3-year all-cause death. Diverse time-dependent variables from prehospitalization to the postdischarge period influenced the major outcomes after AMI. Understanding the complexity and dynamic associations of risk factors may facilitate clinical interventions in patients with AMI. | Jeong, Joo Hee; Lee, Kwang-Sig; Park, Seong-Mi; Kim, So Ree; Kim, Mi-Na; Chae, Shung Chull; Hur, Seung-Ho; Seong, In Whan; Oh, Seok Kyu; Ahn, Tae Hoon; Jeong, Myung Ho | Korea Univ Med, Anam Hosp, Dept Internal Med, Div Cardiol, Seoul, South Korea; Korea Univ, Anam Hosp, AI Ctr, Coll Med, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Med Genet, Daegu, South Korea; Chungnam Natl Univ, Chungnam Natl Univ Hosp, Coll Med, Dept Internal Med, Daejeon, South Korea; Wonkwang Univ, Sch Med, Dept Internal Med, Div Cardiol, Iksan, South Korea; Na eun Hosp, Dept Cardiol, Incheon, South Korea; Chonnam Natl Univ Hosp, Dept Cardiol, Gwangju, South Korea | Kim, Young/T-8521-2019; Jeong, JooHee/KHT-5684-2024; Kim, Hyung-Kwan/ITU-6159-2023 | 57547817300; 57221177656; 35362623600; 57200555884; 55686260600; 7101962036; 34570274500; 35254371300; 24734336000; 57222278496; 56485157500 | smparkmd@korea.ac.kr;myungho@chollian.net; | FRONTIERS IN CARDIOVASCULAR MEDICINE | FRONT CARDIOVASC MED | 2297-055X | 11 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS | 2024 | 2.9 | 34.6 | 1.82 | 2025-04-16 | 4 | 3 | body mass index; machine learning analysis; myocardial infarction; artificial intelligence; prediction model | ACUTE CORONARY SYNDROME; OBESITY PARADOX; ELEVATION; RISK; DEATH | artificial intelligence; body mass index; machine learning analysis; myocardial infarction; prediction model | amino terminal pro brain natriuretic peptide; brain natriuretic peptide; C reactive protein; cholesterol; fibrinogen receptor; glucose; high density lipoprotein cholesterol; hydroxymethylglutaryl coenzyme A reductase inhibitor; myoglobin; ticagrelor; triacylglycerol; troponin; troponin I; troponin T; acute heart infarction; adult; area under the curve; Article; artificial intelligence; cardiovascular risk; cholesterol blood level; clinical outcome; cohort analysis; decision tree; door-to-balloon time; extracorporeal oxygenation; female; heart left ventricle ejection fraction; hemodynamics; hospitalization; human; learning algorithm; longitudinal study; machine learning; major clinical study; male; random forest; risk assessment; risk factor; support vector machine | English | 2024 | 2024-04-05 | 10.3389/fcvm.2024.1340022 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Real-world effectiveness of influenza vaccine over a decade during the 2011-2021 seasons-Implications of vaccine mismatch | Background: Influenza imposes a significant healthcare burden in Korea, leading the government to initiate a national immunization program. Previous studies on vaccine effectiveness (VE) were limited to single-season estimation in Korea. Methods: This multicenter prospective cohort study enrolled patients with influenza-like illnesses at 10 medical centers in Korea from 2011 to 2021. The demographic and clinical data were collected from questionnaire surveys and electronic medical records. Using a test-negative design, we aimed to investigate the effectiveness of a seasonal influenza vaccine for antigenic matching of the vaccine and circulating viral strains over 10 seasons. Results: Overall, 5322 adults aged >= 65 years were enrolled. Only three (33.3 %) of nine seasons showed >70 % antigenic match between vaccine and circulating strains. Influenza VE was significantly variable by season, ranging from -46.9 % (95 %confidence interval [CI]: -127.6-5.2) in the 2011/12 season to 47.7 % (95 %CI: 22.6-64.7) in the 2016/17 season. A significant difference was observed in the VE depending on whether the vaccine strains matched with epidemic strains: 28.8 % (95 %CI: 8.8-44.8) in matched seasons versus -12.0 % (95 %CI: -30.0-3.7) in mismatched seasons. Across the study period, influenza-related hospitalizations were reduced by 13.6 % (95 %CI: 0.7-24.8) with vaccination. In a subgroup analysis, the VE against influenza-related hospitalization was 48.4 % (95 %CI 29.6-62.2) in A/H3N2 dominant seasons and 53.8 % (95 %CI: -73.4-87.7) in A/H1N1 dominant seasons, respectively. Conclusion: Influenza vaccine mismatch was frequent over the study period, leading to negligibly low VE in mismatched seasons. Influenza vaccination reduces the risk of influenza-related hospitalizations. | Choi, Yu Jung; Song, Joon Young; Wie, Seong-Heon; Choi, Won Suk; Lee, Jacob; Lee, Jin-Soo; Kim, Young Keun; Kim, Shin Woo; Lee, Sun Hee; Park, Kyung-Hwa; Jeong, Hye Won; Yoon, Jin Gu; Seong, Hye; Nham, Eliel; Noh, Ji Yun; Cheong, Hee Jin; Kim, Woo Joo | Korea Univ, Coll Med, Dept Internal Med, Div Infect Dis,Guro Hosp, 148 Gurodong Ro, Seoul 08308, South Korea; KU Med VIC K, Vaccine Innovat Ctr, Seoul 02841, South Korea; Catholic Univ Korea, St Vincents Hosp, Coll Med, Dept Internal Med,Div Infect Dis, Suwon, South Korea; Korea Univ, Coll Med, Dept Internal Med, Div Infect Dis,Ansan Hosp, Ansan, South Korea; Hallym Univ, Coll Med, Dept Internal Med, Div Infect Dis,Kangdong Sacred Heart Hosp, Seoul, South Korea; Inha Univ, Sch Med, Dept Internal Med, Div Infect Dis, Incheon, South Korea; Yonsei Univ, Wonju Coll Med, Dept Internal Med, Div Infect Dis, Wonju, South Korea; Kyungpook Natl Univ, Sch Med, Div Infect Dis, Dept Internal Med, Daegu, South Korea; Pusan Natl Univ, Sch Med, Dept Internal Med, Div Infect Dis, Pusan, South Korea; Chonnam Natl Univ, Dept Internal Med, Div Infect Dis, Med Sch, Gwangju, South Korea; Chungbuk Natl Univ, Dept Internal Med, Coll Med, Cheongju, Chungbuk, South Korea | ; Choi, Yu Jung/HOF-0843-2023; Kim, Woo/D-2733-2015; Choi, Won Suk/V-2730-2017; Lee, Sunhee/L-8902-2017; Nham, Eliel/AFP-2784-2022; Choi, Won/V-2730-2017; Jeong, Hye/AET-1982-2022 | 57914887600; 57214400146; 12796392700; 56718971800; 13406664300; 56162297100; 35322538300; 8710731500; 56498686800; 57219637574; 13103042700; 57104165700; 57193717138; 57190045330; 24587375200; 7102495865; 59207541300 | wjkim@korea.ac.kr; | VACCINE | VACCINE | 0264-410X | 1873-2518 | 42 | 26 | SCIE | IMMUNOLOGY;MEDICINE, RESEARCH & EXPERIMENTAL | 2024 | 3.5 | 34.6 | 0.83 | 2025-05-07 | 4 | 3 | Vaccine; Vaccine effectiveness; Influenza; Influenza vaccine; Hospitalization | Hospitalization; Influenza; Influenza vaccine; Vaccine; Vaccine effectiveness | Aged; Aged, 80 and over; Female; Humans; Influenza A Virus, H1N1 Subtype; Influenza A Virus, H3N2 Subtype; Influenza Vaccines; Influenza, Human; Male; Prospective Studies; Republic of Korea; Seasons; Vaccination; Vaccine Efficacy; influenza vaccine; influenza vaccine; vaccine; aged; Article; cardiovascular disease; chronic kidney failure; chronic liver disease; chronic obstructive lung disease; cohort analysis; diabetes mellitus; efficacy parameters; electronic medical record; female; hospitalization; human; hypertension; influenza; major clinical study; male; multicenter study; prospective study; questionnaire; clinical trial; epidemiology; immunology; influenza; Influenza A virus (H1N1); Influenza A virus (H3N2); prevention and control; season; South Korea; vaccination; very elderly | English | 2024 | 2024-12-02 | 10.1016/j.vaccine.2024.126381 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Trends in the prescription of opioids and gabapentinoids in patients with failed back surgery syndrome in Korea: a population-based study | Background: Failed back surgery syndrome (FBSS) is a chronic condition that is characterized by persistent back pain following one or more spinal surgeries. Pharmacological interventions, such as the use of opioids and gabapentinoids, are frequently used in the treatment of FBSS. However, prolonged and excessive use of these medications can lead to dependence and adverse effects. This study investigates trends in opioid and gabapentinoid prescriptions among patients with FBSS in Korea from 2016 to 2020.Methods: Data from the Health Insurance and Review Agency were analyzed, and claims listing FBSS were selected for the study. Prescription patterns of opioids and gabapentinoids were classified based on the number of days prescribed per year.Results: Of the 390,095 patients diagnosed with FBSS, 41.6% of the patients were prescribed gabapentinoids, and 42.0% of them were prescribed opioids, while 10.6% of the patients were classified as long-term gabapentinoid users, 11.4% as long-term opioid users, and 7.4% of the patients were found to have long-term prescriptions for both drugs. The proportion of patients who received both gabapentinoid and opioid prescriptions increased annually. The doses of opioids prescribed have also increased along with the increase in the number of patients receiving opioid prescriptions. Conclusions: The prescription rates of opioids and gabapentinoids among patients with FBSS in Korea continue to increase steadily, posing potential risks of addiction and adverse effects. Further research is needed to better understand the actual status of addiction in patients with FBSS. | Oh, Jinyoung; Yeo, Jinseok | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Anesthesiol & Pain Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Anesthesiol & Pain Med, 807 Hoguk Ro, Daegu 41404, South Korea | 57609999900; 35072322000 | painfree@gmail.com; | KOREAN JOURNAL OF PAIN | KOREAN J PAIN | 2005-9159 | 2093-0569 | 37 | 1 | SCIE | CLINICAL NEUROLOGY | 2024 | 3.1 | 34.6 | 1.52 | 2025-04-16 | 2 | 2 | Analgesics, Opioid; Big Data; Drug-Related Side Effects and Adverse Reactions; Failed Back Surgery Syndrome; Gabapentin; Insurance, Health; National Health Programs; Pregabalin; Prescriptions | SPINAL-CORD STIMULATION; CHRONIC PAIN; CANCER PAIN; THERAPY; ABUSE; MANAGEMENT; EFFICACY | Analgesics; Health; National Health Programs; Pregabalin; Prescriptions; Opioid; Big Data; Drug-Related Side Effects and Adverse Reactions; Failed Back Surgery Syndrome; Gabapentin; Insurance | codeine; dihydrocodeine; fentanyl; gabapentin; hydrocodone; hydromorphone; morphine; opiate; oxycodone; tapentadol; tramadol; Article; drug use; failed back surgery syndrome; female; human; Korea; major clinical study; male; morphine equivalent dose; population research; prescribing practice; prescription | English | 2024 | 2024-01 | 10.3344/kjp.23246 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Updated guidelines for prescribing opioids to treat patients with chronic non-cancer pain in Korea: developed by committee on hospice and palliative care of the Korean Pain Society | There are growing concerns regarding the safety of long-term treatment with opioids of patients with chronic noncancer pain. In 2017, the Korean Pain Society (KPS) developed guidelines for opioid prescriptions for chronic non -cancer pain to guide physicians to prescribe opioids effectively and safely. Since then, investigations have provided updated data regarding opioid therapy for chronic non -cancer pain and have focused on initial dosing schedules, reassessment follow-ups, recommended dosage thresholds considering the risk -benefit ratio, dosereducing schedules for tapering and discontinuation, adverse effects, and inadvertent problems resulting from inappropriate application of the previous guidelines. Herein, we have updated the previous KPS guidelines based on a comprehensive literature review and consensus development following discussions among experts affiliated with the Committee on Hospice and Palliative Care in the KPS. These guidelines may assist physicians in prescribing opioids for chronic non -cancer pain in adult outpatient settings, but should not to be regarded as an inflexible standard. Clinical judgements by the attending physician and patient -centered decisions should always be prioritized. | Kim, Minsoo; Park, Sun Kyung; Kim, Woong Mo; Kim, Eunsoo; Kim, Hyuckgoo; Park, Jun-Mo; Choi, Seong-Soo; Choi, Eun Joo | Kangwon Natl Univ, Kangwon Natl Univ Hosp, Coll Med, Dept Anesthesiol & Pain Med, Chunchon, South Korea; Jeju Natl Univ, Coll Med, Dept Anesthesiol & Pain Med, Jeju, South Korea; Chonnam Natl Univ, Med Sch, Dept Anesthesiol & Pain Med, 160 Baekseo Ro, Gwangju 61469, South Korea; Pusan Natl Univ, Sch Med, Dept Anesthesia & Pain Med, Pusan, South Korea; Yeungnam Univ, Coll Med, Dept Anesthesiol & Pain Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Anesthesiol & Pain Med, Daegu, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Anesthesiol & Pain Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Anesthesiol & Pain Med, Seongnam, South Korea | ; Choi, Seong-Soo/ACP-8243-2022; Kim, Eunsoo/AAJ-5077-2021 | 57207922632; 57204538992; 8954772900; 57202989732; 56571641100; 55967725100; 57313322600; 55555594000 | kimwm@jnu.ac.kr; | KOREAN JOURNAL OF PAIN | KOREAN J PAIN | 2005-9159 | 2093-0569 | 37 | 2 | SCIE | CLINICAL NEUROLOGY | 2024 | 3.1 | 34.6 | 2.08 | 2025-04-16 | 5 | 4 | Adult; Analgesics; Chronic Pain; Drug Monitoring; Drug Prescriptions; Opioid-Related Disorders; Prescription Drug Misuse; Treatment Outcome | SUBSTANCE-USE DISORDERS; DEPENDENCE; ADDICTION; PRESCRIPTION; MANAGEMENT; ABUSE; WORD | Adult; Analgesics; Chronic Pain; Drug Monitoring; Drug Prescriptions; Opioid-Related Disorders; Prescription Drug Misuse; Treatment Outcome | codeine; fentanyl; hydrocodone; hydromorphone; morphine; opiate; oxycodone; tapentadol; chronic pain; cognitive defect; constipation; drug dose titration; drug monitoring; DSM-5; follow up; hallucination; human; Korea; long term care; maintenance therapy; myoclonus; nausea and vomiting; numeric rating scale; opiate addiction; pain intensity; palliative therapy; person centered care; physical examination; practice guideline; prescribing guideline; pruritus; psychologic assessment; Review; somnolence; treatment outcome; urine retention; visual analog scale | English | 2024 | 2024-04 | 10.3344/kjp.24022 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Comparison of clinical characteristics and outcomes in candidaemia patients with and without COVID-19: a multicentre retrospective study | Background Invasive fungal infections have been reported as complications with significant mortality and morbidity in patients hospitalized with COVID-19. This study aimed to evaluate the clinical characteristics and outcomes of candidaemia patients with COVID-19 and to investigate the association between COVID-19 and mortality in candidaemia patients. Methods This retrospective study included candidaemia patients aged 18 years or older admitted to four university-affiliated tertiary hospitals in South Korea between January 1, 2020, and December 31, 2022. The COVID-19 group comprised patients diagnosed with COVID-19 before the onset of candidaemia. Clinical features and outcomes were compared between the COVID-19 and non-COVID-19 groups. Multivariate logistic regression analyses were performed to identify risk factors related to 30-day mortality. Results Of the 355 patients diagnosed with candidaemia, 39 (11.0%) had a prior diagnosis of COVID-19. The COVID-19 group exhibited greater rates of systemic corticosteroid use (20.5% vs. 8.9%, p = 0.042), central venous catheter use (74.4% vs. 57.3%, p = 0.041), and mechanical ventilation (53.8% vs. 31.6%, p = 0.006) before the onset of candidaemia. The COVID-19 group had a greater rate of septic shock at the onset of candidaemia (61.5% vs. 32.0%, p < 0.0001) and a greater 30-day mortality rate (69.2% vs. 50.9%, p = 0.031). K-M survival analysis revealed that patients in the COVID-19 group had a lower 30-day survival rate than did those without COVID-19 (p = 0.003 by log-rank test). However, in multivariate logistic regression analysis, COVID-19 did not significantly impact 30-day mortality. Conclusions According to multivariate logistic regression analysis, COVID-19 was not an independent risk factor for mortality. However, candidaemia patients with a prior COVID-19 diagnosis were more likely to exhibit critical conditions such as mechanical ventilation and experience poor outcomes. Therefore, clinicians need to monitor and prevent candidaemia in critically ill patients with COVID-19. | Shin, Sung Un; Bae, Sohyun; Cho, David; Lee, Ahrang; Jeong, Hae Seong; Hwang, Soyoon; Kim, Sarah; Kim, Minji; Kim, Seong Eun; Kim, Uh Jin; Kang, Seung-Ji; Park, Kyung-Hwa; Chang, Hyun-Ha; Jung, Sook In | Chonnam Natl Univ, Med Sch, Dept Infect Dis, Dept Internal Med, 42 Jebong Ro, Gwangju 61469, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Internal Med, Div Infect Dis,Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea | Hwang, Soyoon/HHM-5762-2022; Kim, Sooyeon/AAA-8521-2022; Kim, Sung/AAI-3081-2021; JUNG, SOOK IN/AGO-2862-2022 | 57212901754; 57219699506; 59477890400; 57218497443; 57216763128; 57203160675; 59477776100; 57219980756; 57226683401; 55606990600; 37072777000; 57219637574; 7407521688; 7403676835 | changhha@knu.ac.kr;sijung@chonnam.ac.kr; | BMC INFECTIOUS DISEASES | BMC INFECT DIS | 1471-2334 | 24 | 1 | SCIE | INFECTIOUS DISEASES | 2024 | 3 | 34.7 | 0.68 | 2025-05-07 | 2 | 2 | Candidaemia; COVID-19; Mortality; Mechanical ventilation | RISK-FACTORS; MORTALITY; EPIDEMIOLOGY; INFECTIONS; CANDIDEMIA | Candidaemia; COVID-19; Mechanical ventilation; Mortality | Adult; Aged; Aged, 80 and over; Candidemia; COVID-19; Female; Humans; Male; Middle Aged; Republic of Korea; Respiration, Artificial; Retrospective Studies; Risk Factors; SARS-CoV-2; corticosteroid; glucocorticoid; prednisone; abdominal infection; absolute neutrophil count; aged; antifungal therapy; Article; artificial ventilation; candidemia; catheter infection; cerebrovascular accident; Charlson Comorbidity Index; chronic kidney failure; chronic liver failure; chronic lung disease; clinical outcome; comparative study; congestive heart failure; coronavirus disease 2019; diabetes mellitus; disease surveillance; extracorporeal oxygenation; female; hematologic disease; human; intensive care unit; major clinical study; male; matrix assisted laser desorption ionization time of flight mass spectrometry; middle aged; morbidity; mortality; multicenter study; neutropenia; retrospective study; sepsis; septic shock; adult; candidemia; clinical trial; comparative study; complication; epidemiology; risk factor; Severe acute respiratory syndrome coronavirus 2; South Korea; therapy; very elderly | English | 2024 | 2024-12-28 | 10.1186/s12879-024-10373-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of a new sterilization method for microalgae media using calcium hypochlorite as the sterilant | Calcium hypochlorite (Ca(ClO)2), which can be stably stored in powder form for a long period, is widely used as a disinfectant in various fields. A new sterilization process was developed in the present study, where a microalgal medium was sterilized using 0.02% Ca(ClO)2, followed by complete neutralization of the Ca(ClO)2 within 8 h through catalytic reaction of an MnCl2-Na2EDTA complex and a synergistic effect of glucose. When comparing the growth of Chlorella vulgaris in the autoclaved medium, a 2.65 times greater maximum cell growth was observed in cells grown in the medium prepared by treatment of Ca(ClO)2. This result indicates that denaturation of the medium by heat can hinder the growth of some microorganisms. In the case of cultivation of Euglena gracilis, successful culture growth was achieved without growth inhibition or contamination on a medium prepared in the same manner. | Jeong, Seong-Hun; Kim, Woong; Kwon, Jong-Hee | Gyeongsang Natl Univ, Div Appl Life Sci BK21, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Food Sci & Technol, Jinju 52828, South Korea; Gyeongsang Natl Univ, Inst Agr & Life Sci, Jinju 52828, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | 57212175840; 55581636400; 55972283900 | elshine@knu.ac.kr;jhkwon@gnu.ac.kr; | BIOPROCESS AND BIOSYSTEMS ENGINEERING | BIOPROC BIOSYST ENG | 1615-7591 | 1615-7605 | 47 | 3 | SCIE | ENGINEERING, CHEMICAL;BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.6 | 34.7 | 0 | 2025-05-07 | 0 | 0 | Chemical sterilization; Calcium hypochlorite; Manganese chloride; Euglena; Chlorella | SODIUM-HYPOCHLORITE; CULTIVATION | Calcium hypochlorite; Chemical sterilization; Chlorella; Euglena; Manganese chloride | Biomass; Calcium Compounds; Chlorella vulgaris; Microalgae; Sterilization; Calcium; Catalysis; Cell proliferation; Chlorine compounds; Manganese compounds; Microorganisms; Sodium compounds; Sterilization (cleaning); calcium hypochlorite; disinfectant agent; edetate sodium; glucose; manganese chloride; oxidizing agent; unclassified drug; calcium derivative; calcium hypochlorite; Catalytic reactions; Chemical sterilization; Chlorella vulgaris; Chlorellum; EDTA complex; Euglenum; Micro-algae; Neutralisation; Sterilization process; Synergistic effect; algal cell culture; algal growth; Article; autoclaving; catalysis; cell growth; chemical sterilization; Chlorella vulgaris; complex formation; decomposition; degradation; denaturation; Euglena gracilis; growth curve; heat treatment; nonhuman; spectrophotometry; biomass; instrument sterilization; microalga; Calcium hypochlorite | English | 2024 | 2024-03 | 10.1007/s00449-024-02971-z | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A Model-Based Approach to Enhance the Communication Between the Participants of Collaborative Business Processes | Business process modeling is used to model business processes using Business Process Modeling Notation (BPMN), which is a widely accepted standard for process modeling. BPMN elements are visually represented by the existing model, but the expressiveness of elements in terms of communication between the participants of the business process is a problem reported in modeling literature. Business processes use collaboration models to gain increasing importance in software development, describing their behavior and interaction. Recent years have seen the presentation of various approaches to ensure communication between business process pools. Despite the widespread adoption of BPMN for business process modeling, existing collaboration models often suffer from significant limitations in accurately capturing complex collaborative business processes. The existing approaches do not ensure proper structure and syntax for collaboration elements. The flow of information among multiple pools causes ambiguity in the developed business process. A Collaborative Business Process Model (CBPM) is proposed to address this issue, based on modeling rules that ensure proper syntax and structure of the models. The proposed CBPM also guarantees that the model is a better approach for participant interaction. This approach contributes to improving the communication mechanism between the participants of collaborative business processes. Moreover, we formally analyze and verify the working of CBPM by specifying the model in Z specification language. Performance evaluation regarding the flow of messages through test case coverage criteria indicates that the model is capable of ensuring successful communication among the multiple participants of business processes. | Murtaza, Amber; Rehman, Abdul; Malik, Saif Ur Rehman; Ahmed, Gouher; Abbas, Assad; Khan, Muhammad Adnan | COMSATS Univ Islamabad, Dept Comp Sci, Islamabad 45550, Pakistan; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Univ Dublin, Trinity Coll Dublin, Sch Comp Sci & Stat, Dublin D02PN40, Ireland; Skyline Univ Coll, Sch Business, Sharjah, U Arab Emirates; Gachon Univ, Fac Artificial Intelligence & Software, Dept Software, Seongnam 13557, South Korea | Khan, Muhammad Adnan/ACJ-2841-2022; Rehman, Abdul/D-5630-2019 | 59308296200; 57200894071; 26666195700; 57195348163; 56349574400; 57226797214 | a.rehman.knu@knu.ac.kr;adnan@gachon.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 12 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 3.6 | 34.8 | 0 | 2025-05-07 | 0 | 0 | Collaboration; Syntactics; Process modeling; Organizations; Uncertainty; Business communication; User experience; Performance evaluation; Business process modeling; collaborative business processes; syntactic; structural; participants | Business process modeling; collaborative business processes; participants; structural; syntactic | Business Process; Business process modeling; Collaboration; Collaborative business process; Model based approach; Modeling notation; Participant; Process-models; Structural; Uncertainty | English | 2024 | 2024 | 10.1109/access.2024.3450690 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Zero-Trust Authentication Scheme With Access Control for 6G-Enabled IoT Environments | The sixth generation (6G) is the next generation of wireless communication technology, is not limited to cellular networks but can be used to provide better services in all areas of wireless communication, including vehicles, drones, and smart homes. However, these advancements in 6G technology require further security considerations. In earlier networks, authentication schemes were designed to rely on a secure channel between the core network and access points. The 6G network is an open, distributed network that integrates multiple domains and entities and cannot guarantee secure channels in the network. The 6G network requires a new security authentication scheme that applies the zero-trust model. Therefore, this study proposes a zero-trust authentication scheme with access control for 6G-enabled Internet of Things environments. The scheme uses blockchain technology for mutual authentication in a distributed environment and lightweight attribute-based encryption to ensure dynamic access control and network efficiency. This study compares the proposed authentication method with existing methods and demonstrates that this scheme has better performance and security. To the best of our knowledge, this paper is the first to propose a specific authentication protocol with access control considering the zero-trust model in a 6G environment. | Son, Seunghwan; Kwon, Deokkyu; Lee, Sangwoo; Kwon, Hyeokchan; Park, Youngho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Cyber Secur Res Div, Daejeon 34129, South Korea | 57221744477; 57221739597; 57201864359; 12645964200; 56962990300 | parkyh@knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 12 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 3.6 | 34.8 | 0.77 | 2025-05-07 | 1 | 3 | 6G mobile communication; Authentication; Security; Access control; Internet of Things; Blockchains; Protocols; 5G mobile communication; Drones; Base stations; Encryption; Zero Trust; attribute-based encryption; authentication; blockchain; key agreement; sixth generation (6G); zero-trust | MANAGEMENT; BLOCKCHAIN; PROTOCOL; SECURITY; INTERNET; DESIGN | Access control; attribute-based encryption; authentication; blockchain; key agreement; sixth generation (6G); zero-trust | Attribute-based encryptions; Authentication scheme; Block-chain; Cellular network; Key agreement; Secure channels; Sixth generation (6g); Trust models; Wireless communication technology; Zero-trust | English | 2024 | 2024 | 10.1109/access.2024.3484522 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Advanced Calibration and Compensation for Nonlinearities in Ball Joint-Integrated Hall Sensors for Accurate Ride Height Measurement | This study is motivated by the critical need for accurate and durable ride height sensors in modern automotive systems, particularly as these sensors play a crucial role in maintaining vehicle stability and safety. Current sensors' susceptibility to environmental damage and inherent nonlinearities highlight the necessity for improved sensor designs and nonlinearity correction algorithms. To address these issues, this study proposes a novel sensor system that integrates a ball joint and a Hall sensor to enhance the accuracy and durability of ride height sensors and develops a Real-time Nonlinearity Correction and Calibration (RNCC) Algorithm for real-time correction. The RNCC algorithm combines Model Reference Adaptive Control (MRAC), Kalman filtering, and nonlinear optimization techniques to correct sensor nonlinearity in real-time, enabling precise position measurement. Experimental results demonstrate that the RNCC algorithm can calibrate sensors more quickly and accurately than existing methods and is effective in handling outlier data. This research suggests the potential for the RNCC algorithm to be applied in various real-time control applications and contribute to improving automotive suspension systems. | Jung, Minwoo; Kim, Dae-Young | Kyungpook Natl Univ, Ctr Selforganizing Software, Daegu 41566, South Korea; Soonchunhyang Univ, Dept Comp Software & Engn, Asan 31538, South Korea | 55517112600; 58378650900 | dyoung.kim@sch.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 12 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 3.6 | 34.8 | 0 | 2025-05-07 | 0 | 0 | Sensors; Magnetic sensors; Sensor systems; Accuracy; Sensor phenomena and characterization; Optical sensors; Real-time systems; Ultrasonic variables measurement; Reliability; Calibration; Hall sensor calibration; ball joint integration; ride height measurement; nonlinear compensation; real-time nonlinear compensation and calibration (RNCC) | ball joint integration; Hall sensor calibration; nonlinear compensation; real-time nonlinear compensation and calibration (RNCC); ride height measurement | Adaptive filtering; Adaptive filters; Automobile safety devices; Automobile suspensions; Control nonlinearities; Hall effect transducers; Kalman filters; Magnetic levitation vehicles; Ball joint integration; Ball joints; Hall sensor; Hall sensor calibration; Height Measurement; Nonlinear calibration; Nonlinear compensation; Real- time; Real-time nonlinear compensation and calibration; Ride height measurement; Sensor calibration; Model reference adaptive control | English | 2024 | 2024 | 10.1109/access.2024.3505257 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Asynchronous Dual-Channel Controller Area Network for Tolerating Inconsistent Message Omission and Duplication | Latest intelligent vehicles require a higher level of reliability for controller area network (CAN). Furthermore, the spread of electric vehicles may worsen the problem of electromagnetic interference. Severe electromagnetic interference can affect the bit error rate of the frames being communicated, leading to more frequent inconsistent message omission (IMO) or inconsistent message duplication (IMD) faults, which can be attributed to defects in the retransmission mechanism of CAN. To address the problems of IMO and IMD, this paper presents a dual-channel network structure and corresponding operating protocol, named as fault-tolerant dual-channel CAN. The IMO occurrence rate is maintained at a considerably low level by employing a dual-channel CAN over which replicate messages are transmitted. At the same time, any duplicate frames caused by IMD are identified and removed by analyzing the frame reception time. The integrity of the proposed network structure and operating protocol are evaluated through formal verification. | Song, Moogeun; Lee, Dongik | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Elect Engn, Daegu 41566, South Korea | 25930551000; 59510716800 | dilee@ee.knu.ac.kr; | IEEE ACCESS | IEEE ACCESS | 2169-3536 | 12 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 3.6 | 34.8 | 0 | 2025-05-07 | 0 | 0 | Standards; Protocols; Hardware; Bandwidth; Synchronization; Delays; Bit error rate; Time factors; Stars; Reliability engineering; Controller area network (CAN); controller area network flexible data rate (CAN FD); dual-channel; fault tolerant; inconsistent message duplication (IMD); inconsistent message omission (IMO); network fault tolerance; road vehicle reliability | SCHEDULABILITY ANALYSIS; COMMUNICATION; ALGORITHM; DESIGN | controller area network (CAN); controller area network flexible data rate (CAN FD); dual-channel; fault tolerant; inconsistent message duplication (IMD); inconsistent message omission (IMO); network fault tolerance; road vehicle reliability | Control system synthesis; Fault tolerance; Magnetic levitation vehicles; Controller area network; Controller area network flexible data rate; Controller-area network; Data-rate; Dual channel; Fault-tolerant; Inconsistent message duplication; Inconsistent message omission; Network fault tolerances; Road vehicle reliability; Road vehicles; Vehicle reliability; Road vehicles | English | 2024 | 2024 | 10.1109/access.2024.3511997 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
