| ○ | ○ | Article | Nidus vespae Built by an Invasive Alien Hornet, Vespa velutina nigrithorax, Inhibits Adipose Tissue Expansion in High-Fat Diet-Induced Obese Mice | Simple Summary Nidus vespae (NV) has been used as an ingredient in crude drugs in Korea and China. However, the effects of NV on obesity and its mechanism have not been completely elucidated. Herein, we demonstrated the novel anti-obesity effects of NV in in vivo and in vitro systems. The administration of NV ameliorated adipose expansion and improved adipose browning in white adipose tissue from high-fat diet (HFD)-fed mice. Moreover, treatment with NV suppressed adipocyte differentiation, possibly through inactivation of the insulin signaling pathway in adipocytes. Nidus vespae, commonly known as the wasp nest, has antioxidative, anti-inflammatory, antimicrobial, and antitumor properties. However, the anti-obesity effects of Nidus vespae extract (NV) have not yet been reported. This study aimed to elucidate the potential anti-obesity effects of NV in vivo and in vitro, using a high-fat diet (HFD)-induced obese mouse model and 3T3-L1 adipocytes, respectively. NV administration to HFD-induced obese mice significantly decreased the mass and plasma lipid content of adipose tissues. Uncoupling protein-1 expression was significantly higher in the inguinal white adipose tissues of NV-treated mice than in those of HFD-fed mice. Furthermore, we found that NV inhibited the differentiation and intracellular lipid accumulation of 3T3-L1 adipocytes by regulating the insulin signaling cascade, including protein kinase B, peroxisome proliferator-activated receptor gamma, CCAAT/enhancer binding protein alpha, and adiponectin. These findings suggest that NV may exhibit therapeutic effects against obesity by suppressing adipose tissue expansion and preadipocyte differentiation, thereby providing critical information for the development of new drugs for disease prevention and treatment. To our knowledge, this study provides the first evidence of the anti-obesity effects of NV. | Lee, Seul Gi; Kim, Dong Se; Chae, Jongbeom; Lee, Eunbi; Hahn, Dongyup; Kim, Il-Kwon; Kim, Chang-Jun; Choi, Moon Bo; Nam, Ju-Ock | Kyungpook Natl Univ, Dept Food Sci & Biotechnol, Daegu 41566, South Korea; Keimyung Univ, Sch Med, Dept Immunol, Daegu 42601, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Korea Natl Arboretum, Div Forest Biodivers, Pochon 30106, South Korea; Kyungpook Natl Univ, Inst Plant Med, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Tailored Food Technol, Daegu 41566, South Korea | ; KIm, Changjun/GZM-7308-2022 | 56995397800; 57220072584; 57204499421; 57798039800; 36554163400; 59059173500; 55286588300; 51863232400; 7201496105 | lsg100479@naver.com;aodydirk@naver.com;chejongbum@naver.com;21eunbi@naver.com;dohahn@knu.ac.kr;ilkwons91@forest.go.kr;changjunkim@korea.kr;mbchoi@knu.ac.kr;namjo@knu.ac.kr; | BIOLOGY-BASEL | BIOLOGY-BASEL | 2079-7737 | 11 | 7 | SCIE | BIOLOGY | 2022 | 4.2 | 26.6 | 0.22 | 2025-06-25 | 2 | 2 | adipogenesis; adipose browning; insulin signaling; Nidus vespae; obesity | FOOD; DIFFERENTIATION; ADIPOGENESIS; INFLAMMATION; ANTIOXIDANT; COMPETITION; ADIPOCYTES; IMPACT | adipogenesis; adipose browning; insulin signaling; Nidus vespae; obesity | English | 2022 | 2022-07 | 10.3390/biology11071013 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | OsbHLHq11, the Basic Helix-Loop-Helix Transcription Factor, Involved in Regulation of Chlorophyll Content in Rice | Simple Summary R-ice is one of the world's most important staples; a growing population and declining rates of growth in rice yields will present significant challenges ahead. After the heading stage, the photosynthetic ability of the flag leaf has a great effect on the yield of rice, and this ability can be evaluated by leaf color, chlorophyll content, quantum yield, etc. Our purpose was to screen candidate genes that affect photosynthetic efficiency through QTL mapping analysis and predict their function through protein interaction and homology sequence analysis. The results suggest that OsbHLHq11 may be involved in chlorophyll accumulation and enhancing photosynthetic efficiency, which may lead to high yields. Photosynthesis is an important factor in determining the yield of rice. In particular, the size and efficiency of the photosynthetic system after the heading has a great impact on the yield. Research related to high-efficiency photosynthesis is essential to meet the growing demands of crops for the growing population. Chlorophyll is a key molecule in photosynthesis, a pigment that acts as an antenna to absorb light energy. Improvement of chlorophyll content characteristics has been emphasized in rice breeding for several decades. It is expected that an increase in chlorophyll content may increase photosynthetic efficiency, and understanding the genetic basis involved is important. In this study, we measured leaf color (CIELAB), chlorophyll content (SPAD), and chlorophyll fluorescence, and quantitative trait loci (QTL) mapping was performed using 120 Cheongcheong/Nagdong double haploid (CNDH) line after the heading date. A major QTL related to chlorophyll content was detected in the RM26981-RM287 region of chromosome 11. OsbHLHq11 was finally selected through screening of genes related to chlorophyll content in the RM26981-RM287 region. The relative expression level of the gene of OsbHLHq11 was highly expressed in cultivars with low chlorophyll content, and is expected to have a similar function to BHLH62 of the Gramineae genus. OsbHLHq11 is expected to increase photosynthetic efficiency by being involved in the chlorophyll content, and is expected to be utilized as a new genetic resource for breeding high-yield rice. | Jang, Yoon-Hee; Park, Jae-Ryoung; Kim, Eun-Gyeong; Kim, Kyung-Min | Kyungpook Natl Univ, Grad Sch, Dept Appl Biosci, Daegu 41566, South Korea; Natl Inst Crop Sci, Crop Breeding Div, Rural Dev Adm, Wonju 55365, South Korea | ; Kim, Kyung-Min Kim/C-7007-2014 | 57219901992; 57211205505; 57221496070; 34868260300 | uniunnie@naver.com;icd0192@korea.kr;dkqkxk632@naver.com;kkm@knu.ac.kr; | BIOLOGY-BASEL | BIOLOGY-BASEL | 2079-7737 | 11 | 7 | SCIE | BIOLOGY | 2022 | 4.2 | 26.6 | 0.78 | 2025-06-25 | 7 | 8 | CIELAB; photosynthesis; QTL; SPAD; yield | ORYZA-SATIVA L.; LEAF SENESCENCE; QTL ANALYSIS; PHOTOSYNTHETIC RATE; STRESS TOLERANCE; GRAIN-YIELD; FLAG LEAVES; GENE; PROTEIN; TRAITS | CIELAB; photosynthesis; QTL; SPAD; yield | English | 2022 | 2022-07 | 10.3390/biology11071000 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sex-specific effect of body mass index and fasting glucose on gastric cancer risk and all causes mortality; a cohort study of 5.17 million | Background Simultaneous evaluation of sex-specific effect of body mass index (BMI) and hyperglycemia on the risk of gastric cancer has been rarely reported. Here, we investigated the sex-specific effect of BMI and hyperglycemia on gastric cancer. Methods Persons who underwent National gastric cancer screening from 2006 to 2007 and had no gastric cancer at baseline, were enrolled and followed up to 2015. The risk of gastric cancer by BMI and glucose was measured using risk ratios (RRs) and 95% confidence intervals (CI). Adjusted Cox analysis was performed to evaluate the risk of death. Results Gastric cancers developed in 29,775 of 5.17 million. In the adjusted analysis, low BMI (= 126 mg/dL; RR, 1.09; 95% CI, 1.05-1.13) increased the risk of gastric cancer. In sex-specific analysis, its risk by BMI was modified L-shape with cut-off value of 23 kg/m(2) in men and 18.5 kg/m(2) in women. Low BMI increased gastric cancer risk in men (RR, 1.39; 95% CI, 1.30-1.50) and women (RR, 1.48; 95% CI, 1.33-1.64). High fasting glucose increased the risk of gastric cancer in women (RR, 1.19; 95% CI, 1.11-1.28), but not in men. Low BMI increased all-cause mortality with cut-off value of 23 kg/m(2) in men and 18.5 kg/m(2) in women. Conclusions Gastric cancer risk and all-cause mortality by BMI was L-shape with sex-specific cut-off value. The effect of fasting glucose on gastric cancer risk was different by sex. | Nam, Su Youn; Jeong, Jihyeon; Lee, Won Kee; Jeon, Seong Woo | Kyungpook Natl Univ Hosp, Gastroenterol, Daegu, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Kyunpook Natl Univ Hosp, Med Res Collaborat Ctr, Biostat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Daegu, South Korea | ; Jeon, Seongwoo/AAU-4618-2020 | 55617028500; 57209972988; 22953484700; 9733636500 | nam20131114@gmail.com; | INTERNATIONAL JOURNAL OF OBESITY | INT J OBESITY | 0307-0565 | 1476-5497 | 46 | 9 | SCIE | ENDOCRINOLOGY & METABOLISM;NUTRITION & DIETETICS | 2022 | 4.9 | 26.6 | 1.28 | 2025-06-25 | 11 | 11 | KOREAN MEN; POPULATION; INSULIN; ADENOCARCINOMA; HYPERGLYCEMIA; METAANALYSIS; ASSOCIATION; ESOPHAGEAL; CARCINOMA; OBESITY | Body Mass Index; Cohort Studies; Fasting; Female; Glucose; Humans; Hyperglycemia; Male; Obesity; Risk Factors; Stomach Neoplasms; glucose; adult; aged; all cause mortality; Article; body mass; cancer mortality; cancer risk; cancer screening; cohort analysis; controlled study; disease course; fasting blood glucose level; female; follow up; hazard ratio; human; hyperglycemia; Kaplan Meier method; major clinical study; male; middle aged; risk factor; sex; stomach cancer; body mass; diet restriction; obesity; stomach tumor | English | 2022 | 2022-09 | 10.1038/s41366-022-01161-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Testing the Performance of Level-Specific Fit Evaluation in MCFA Models With Different Factor Structures Across Levels | A Monte Carlo study was conducted to compare the performance of a level-specific (LS) fit evaluation with that of a simultaneous (SI) fit evaluation in multilevel confirmatory factor analysis (MCFA) models. We extended previous studies by examining their performance under MCFA models with different factor structures across levels. In addition, various design factors and interaction effects between intraclass correlation (ICC) and misspecification type (MT) on their performance were considered. The simulation results demonstrate that the LS outperformed the SI in detecting model misspecification at the between-group level even in the MCFA model with different factor structures across levels. Especially, the performance of LS fit indices depended on the ICC, group size (GS), or MT. More specifically, the results are as follows. First, the performance of root mean square error of approximation (RMSEA) was more promising in detecting misspecified between-level models as GS or ICC increased. Second, the effect of ICC on the performance of comparative fit index (CFI) or Tucker-Lewis index (TLI) depended on the MT. Third, the performance of standardized root mean squared residual (SRMR) improved as ICC increased and this pattern was more clear in structure misspecification than in measurement misspecification. Finally, the summary and implications of the results are discussed. | Lee, Bitna; Sohn, Wonsook | Kyungpook Natl Univ, Daegu, South Korea | 57409318900; 57409145300 | wsohn@knu.ac.kr; | EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT | EDUC PSYCHOL MEAS | 0013-1644 | 1552-3888 | 82 | 6 | SCIE;SSCI | MATHEMATICS, INTERDISCIPLINARY APPLICATIONS;PSYCHOLOGY, EDUCATIONAL;PSYCHOLOGY, MATHEMATICAL | 2022 | 2.7 | 26.6 | 0.36 | 2025-06-25 | 3 | 3 | multilevel confirmatory factor analysis (MCFA); model evaluation method; level-specific (LS) fit evaluation; simultaneous (SI) fit evaluation; partially saturated model (PS) method; Monte Carlo simulation study | COVARIANCE STRUCTURE-ANALYSIS; MULTILEVEL FACTOR-ANALYSIS; EQUATION MODELS; SINGLE-LEVEL; INDEXES | level-specific (LS) fit evaluation; model evaluation method; Monte Carlo simulation study; multilevel confirmatory factor analysis (MCFA); partially saturated model (PS) method; simultaneous (SI) fit evaluation | English | 2022 | 2022-12 | 10.1177/00131644211066956 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | When Do Epidemics End? Scientific Insights from Mathematical Modelling Studies | Quantitative assessments of when infectious disease outbreaks end are crucial, as resources targeted towards outbreak responses typically remain in place until outbreaks are declared over. Recent improvements and innovations in mathematical approaches for determining when outbreaks end provide public health authorities with more confidence when making end-of-outbreak declarations. Although quantitative analyses of outbreaks have a long history, more complex mathematical and statistical methodologies for analysing outbreak data were developed early in the 20th century and continue to be refined. Historically, such methodologies focused primarily on factors affecting the early and middle phases of an outbreak, with less attention given to determining how and when outbreaks end. This review discusses mathematical modelling methods from the last 20 years that have been developed for determining the ends of infectious disease outbreaks, and considers factors that affect the accuracy of such determinations. When disease surveillance systems provide timely and representative data to inform models, the timings of end-of-outbreak declarations can be fine-tuned to allow outbreaks to be declared over quickly and with a low risk of being incorrect. Premature declarations that outbreaks are over can undermine earlier achievements in disease control and may result in a resurgence of cases, but unnecessary delays in declaring outbreaks over can cause significant economic and social harm. Appropriate declarations that balance the benefits of relaxing control measures against the risk of a surge in cases allow public health resources to be conserved (and economic and social pressures to be reduced) while limiting the potential for additional transmission. | Linton, Natalie M.; Lovell-Read, Francesca A.; Southall, Emma; Lee, Hyojung; Akhmetzhanov, Andrei R.; Thompson, Robin N.; Nishiura, Hiroshi | Kyoto Univ, Sch Publ Hlth, Kyoto, Japan; Grad Sch Med, Kyoto, Japan; Univ Oxford, Math Inst, Oxford, England; Univ Warwick, Zeeman Inst Syst Biol & Infect Dis Epidemiol Res, Coventry, W Midlands, England; Kyungpook Natl Univ, Daegu, South Korea; Natl Taiwan Univ, Coll Publ Hlth, Taipei, Taiwan; Univ Warwick, Math Inst, Coventry, W Midlands, England | Linton, Natalie/AGY-8116-2022; Akhmetzhanov, Andrei/B-5530-2013; Nishiura, Hiroshi/JPX-7690-2023 | 57214686285; 57221442204; 57208327831; 57196021198; 18833652300; 57051911800; 7005501836 | Robin.N.Thompson@warwick.ac.uk;nishiura.hiroshi.5r@kyoto-u.ac.jp; | CENTAURUS | CENTAURUS | 0008-8994 | 1600-0498 | 64 | 1 | AHCI;SCIE;SSCI | HISTORY & PHILOSOPHY OF SCIENCE | 2022 | 1.2 | 26.6 | 1.61 | 2025-06-25 | 6 | 8 | epidemics; disease elimination; infectious disease; end-of-outbreak declaration; epidemiological modelling | EBOLA-VIRUS DISEASE; SUBSTANTIATE FREEDOM; INFECTIOUS-DISEASES; QUASI-STATIONARITY; EXTINCTION TIMES; PERSISTENCE; TRANSMISSION; OUTBREAK; ERADICATION; DYNAMICS | disease elimination; end-of-outbreak declaration; epidemics; epidemiological modelling i SSUe Volume 64 (2022); infectious disease; issue 1 | English | 2022 | 2022 | 10.1484/j.cnt.5.130125 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Coordinated Receding-Horizon Control of Battery Electric Vehicle Speed and Gearshift Using Relaxed Mixed-Integer Nonlinear Programming | In this article, we investigate coordinated receding-horizon control of vehicle speed and transmission gearshift for energy-efficient operation of automated battery electric vehicles (BEVs). The introduction of multispeed transmissions in BEVs enables manipulation of electric motor operating point under given vehicle speed and acceleration command, thus creating the opportunity to further improve BEV energy efficiency. However, co-optimizing vehicle speed and transmission gearshift leads to a mixed-integer nonlinear programming (MINLP) problem, and it is well known that solving MINLP problems is computationally very challenging. To address this challenge, we propose a novel continuous relaxation technique that enables the computation of solutions to the speed and gearshift co-optimization problem using off-the-shelf nonlinear programming solvers. After analyzing theoretical properties of the proposed relaxation technique, we demonstrate its effectiveness through simulation-based case studies, where we show that co-optimizing vehicle speed and transmission gearshift can lead to considerably greater energy efficiency than optimizing them separately or sequentially and the proposed relaxation technique can reduce the computational cost of the co-optimization problem to a level that is comparable to the time budget available for onboard implementation. | Li, Nan; Han, Kyoungseok; Kolmanovsky, Ilya; Girard, Anouck | Univ Michigan, Dept Aerosp Engn, Ann Arbor, MI 48109 USA; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | ; Li, Nan/Q-5511-2019 | 57193099518; 56465294700; 7006937254; 7102803626 | nanli@umich.edu;kyoungsh@knu.ac.kr;ilya@umich.edu;anouck@umich.edu; | IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY | IEEE T CONTR SYST T | 1063-6536 | 1558-0865 | 30 | 4 | SCIE | AUTOMATION & CONTROL SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2022 | 4.8 | 26.7 | 0.45 | 2025-06-25 | 5 | 6 | Batteries; Torque; Trajectory; State of charge; Optimization; Gears; Programming; Battery electric vehicle (BEV); energy efficiency; mixed-integer optimization; model predictive control | OPTIMAL ENERGY MANAGEMENT; ECO-DRIVING CONTROL; OPTIMIZATION; ALGORITHMS; EFFICIENT; COMMAND; SAFE | Battery electric vehicle (BEV); energy efficiency; mixed-integer optimization; model predictive control | Battery management systems; Budget control; Charging (batteries); Integer programming; Model predictive control; Nonlinear programming; Problem solving; Secondary batteries; Speed; Vehicle transmissions; Battery electric vehicle; Battery-electric vehicles; Mixed integer optimization; Model predictive control.; Model-predictive control; Optimisations; Programming; Relaxation techniques; States of charges; Vehicle speed; Energy efficiency | English | 2022 | 2022-07 | 10.1109/tcst.2021.3111538 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Leaf blight in Allium monanthum is caused by Botrytis squamosa in South Korea | In recent years, leaf blight has been observed on dalae (Allium monanthum) leaves at Seosan and Tehan regions in South Korea. Disease symptoms include necrotic spots, lesions, and blight on leaves. The pathogen responsible for the disease was successfully isolated from symptomatic leaf tissue using standard phytopathological procedures and identified. Based on morphological features coupled with sequence analyses of glyceraldehyde-3phosphate dehydrogenase (GAPDH), heat-shock protein 60 (HSP60), and DNA-dependent RNA polymerase subunit II (RPB2) genes, fungal isolates were identified as Botrytis squamosa. The pathogenicity was confirmed by artificially inoculating both healthy detached leaves and whole plants of A. monanthum. To the best of our knowledge, this is the first report of leaf blight caused by B. squamosa in dalae in South Korea. | Hassan, Oliul; Kim, Kyung-Min; Shin, Yeong Ung; Chang, Taehyun | Kyungpook Natl Univ, Coll Ecol & Environm Sci, Dept Ecol & Environm Syst, Sangju 37224, Gyeongbuk, South Korea; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Appl Biosci, Daegu 41566, South Korea | Chang, Taehyun/S-1364-2019; Kim, Kyung-Min Kim/C-7007-2014 | 12762464400; 34868260300; 57855295500; 55301101700 | thchang@knu.ac.kr; | CROP PROTECTION | CROP PROT | 0261-2194 | 1873-6904 | 162 | SCIE | AGRONOMY | 2022 | 2.8 | 26.7 | 0.23 | 2025-06-25 | 1 | 2 | Leaf blight; Allium monanthum; Botrytis squamosa; Pathogenicity | IDENTIFICATION; INFECTION; SPP. | Allium monanthum; Botrytis squamosa; Leaf blight; Pathogenicity | Korea; South Korea; pathogenicity | English | 2022 | 2022-12 | 10.1016/j.cropro.2022.106076 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Comparisons of Prehospital Delay and Related Factors Between Acute Ischemic Stroke and Acute Myocardial Infarction | Background Prehospital delay is an important contributor to poor outcomes in both acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We aimed to compare the prehospital delay and related factors between AIS and AMI. Methods and Results We identified patients with AIS and AMI who were admitted to the 11 Korean Regional Cardiocerebrovascular Centers via the emergency room between July 2016 and December 2018. Delayed arrival was defined as a prehospital delay of >3 hours, and the generalized linear mixed-effects model was applied to explore the effects of potential predictors on delayed arrival. This study included 17 895 and 8322 patients with AIS and AMI, respectively. The median value of prehospital delay was 6.05 hours in AIS and 3.00 hours in AMI. The use of emergency medical services was the key determinant of delayed arrival in both groups. Previous history, 1-person household, weekday presentation, and interhospital transfer had higher odds of delayed arrival in both groups. Age and sex had no or minimal effects on delayed arrival in AIS; however, age and female sex were associated with higher odds of delayed arrival in AMI. More severe symptoms had lower odds of delayed arrival in AIS, whereas no significant effect was observed in AMI. Off-hour presentation had higher and prehospital awareness had lower odds of delayed arrival; however, the magnitude of their effects differed quantitatively between AIS and AMI. Conclusions The effects of some nonmodifiable and modifiable factors on prehospital delay differed between AIS and AMI. A differentiated strategy might be required to reduce prehospital delay. | Yoon, Cindy W.; Oh, Hoonji; Lee, Juneyoung; Rha, Joung-Ho; Woo, Seong-Ill; Lee, Won Kyung; Jung, Han-Young; Ban, Byeolnim; Kang, Jihoon; Kim, Beom Joon; Kim, Won-Seok; Yoon, Chang-Hwan; Lee, Heeyoung; Kim, Seongheon; Kim, Sung Hun; Kang, Eun Kyoung; Her, Ae-Young; Cha, Jae-Kwan; Kim, Dae-Hyun; Kim, Moo-Hyun; Lee, Jang Hoon; Park, Hun Sik; Kim, Keonyeop; Kim, Rock Bum; Choi, Nack-Cheon; Hwang, Jinyong; Park, Hyun-Woong; Park, Ki Soo; Yi, SangHak; Cho, Jae Young; Kim, Nam-Ho; Choi, Kang-Ho; Kim, Yongcheol; Kim, Juhan; Han, Jae-Young; Choi, Jay Chol; Kim, Song-Yi; Choi, Joon-Hyouk; Kim, Jei; Jee, Sung Ju; Sohn, Min Kyun; Choi, Si Wan; Shin, Dong-Ick; Lee, Sang Yeub; Bae, Jang-Whan; Lee, Kunsei; Bae, Hee-Joon | Inha Univ, Incheon Reg Cardiocerebrovasc Dis Ctr, Coll Med, Incheon, South Korea; Korea Univ, Dept Biostat, Coll Med, Seoul, South Korea; Seoul Natl Univ, Gyeonggi Reg Cardiocerebrovasc Dis Ctr, Bundang Hosp, Seongnam, South Korea; Kangwon Natl Univ Hosp, Gangwon Reg Cardiocerebrovasc Dis Ctr, Chunchon, South Korea; Dong A Univ Hosp, Busan Ulsan Reg Cardiocerebrovasc Dis Ctr, Busan, South Korea; Kyungpook Natl Univ Hosp, Daegu Gyeongbuk Reg Cardiocerebrovasc Dis Ctr, Daegu, South Korea; Gyeongsang Natl Univ Hosp, Gyeongnam Reg Cardiocerebrovasc Dis Ctr, Jinju, South Korea; Wonkwang Univ Hosp, Jeonbuk Reg Cardiocerebrovasc Ctr, Iksan, South Korea; Chonnam Natl Univ Hosp, Gwangju Jeonnam Reg Cardiocerebrovasc Dis Ctr, Gwangju, South Korea; Jeju Natl Univ Hosp, Jeju Reg Cardiocerebrovasc Dis Ctr, Jeju, South Korea; Chungnam Natl Univ Hosp, Daejeon Chungnam Reg Cardiocerebrovasc Dis Ctr, Daejeon, South Korea; Chungbuk Natl Univ Hosp, Chungbuk Reg Cardiocerebrovasc Dis Ctr, Cheongju, South Korea; Konkuk Univ, Sch Med, Dept Prevent Med, Seoul, South Korea | Kim, Minyeong/JHU-5269-2023; Lee, Sang Yeub/AEQ-6658-2022; lee, hy/GRS-0797-2022; Yoon, Changhwan/MXM-0567-2025; Cho, Young-Seok/J-5670-2012; kim, hyunsoo/LNP-4811-2024; Kim, Song-Yi/JAC-5358-2023; Shin, Dong-Ick/JPK-0914-2023; , 김원석/AAJ-2334-2020; Jeong, Young-Hoon/F-3476-2015; Park, Jin-Young/HDN-0483-2022; Han, Jae-Young/AAV-1100-2021; Kim, Jin-Seok/AAK-5424-2020; Choi, Jong-Il/P-7476-2018; Park, Hang-soo/AEH-1640-2022; Lee, Young/ABA-7224-2020; Yoon, Cindy/HCJ-0079-2022; Kim, Beom Joon/C-2904-2011; Cho, Jae/AAW-7137-2020; Choi, Kangho/HKV-1503-2023; Lee, Jeeyun/I-7171-2015; choi, jo/O-5940-2014; Kim, Seul Kee/A-6076-2015 | 55194639400; 57226878337; 34667876400; 6701393879; 55628587057; 55556575800; 36985347700; 57675928900; 36504184400; 56415337700; 57028735900; 7202882965; 7501482409; 57205219384; 57206875764; 35361799500; 34968030500; 7202455743; 57205425223; 55686265600; 54581258000; 57198844106; 35076059600; 35214909600; 7103324227; 55892914700; 7601564986; 56014252100; 57189687177; 55936313600; 36079407700; 36491173100; 57192112249; 57196169644; 15765035600; 7501392645; 35740671300; 56459207600; 14063316400; 56487143900; 7101840459; 57208291768; 23989448700; 35187345000; 8699381000; 24177393300; 7103223963 | braindoc@snu.ac.kr; | JOURNAL OF THE AMERICAN HEART ASSOCIATION | J AM HEART ASSOC | 2047-9980 | 11 | 9 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS | 2022 | 5.4 | 26.9 | 1.64 | 2025-06-25 | 16 | 15 | acute ischemic stroke; acute myocardial infarction; prehospital delay | EMERGENCY MEDICAL-SERVICES; TIME; CARE; SYMPTOMS; TRIAGE; INTERVENTION; ANGIOPLASTY; GUIDELINES; MANAGEMENT; ADMISSION | acute ischemic stroke; acute myocardial infarction; prehospital delay | Emergency Medical Services; Emergency Service, Hospital; Female; Hospitalization; Humans; Ischemic Stroke; Myocardial Infarction; acute heart infarction; acute ischemic stroke; adult; age; aged; Article; awareness; blood clot lysis; comparative study; coronary artery disease; demographics; emergency ward; female; human; major clinical study; male; middle aged; National Institutes of Health Stroke Scale; prehospital delay; sex difference; South Korea; therapy delay; very elderly; brain ischemia; emergency health service; heart infarction; hospital emergency service; hospitalization | English | 2022 | 2022-05-03 | 10.1161/jaha.121.023214 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Plasma Total Homocysteine Level Is Related to Unfavorable Outcomes in Ischemic Stroke With Atrial Fibrillation | Background Unlike patients with stroke caused by other mechanisms, the effect of elevated plasma total homocysteine (tHcy) on the prognosis of patients with both ischemic stroke and atrial fibrillation (AF) is unknown. This study aimed to evaluate the association between tHcy level and the functional outcome of patients with AF-related stroke. Methods and Results We included consecutive patients with AF-related stroke between 2013 and 2015 from the registry of a real-world prospective cohort from 11 large centers in South Korea. A 3-month modified Rankin Scale score >= 3 was considered an unfavorable outcome. Since tHcy is strongly affected by renal function, we performed a subgroup analysis according to the presence of renal dysfunction. A total of 910 patients with AF-related stroke were evaluated (mean age, 73 years; male sex, 56.0%). The mean tHcy level was 11.98 +/- 8.81 mu mol/L. In multivariable analysis, the tHcy level (adjusted odds ratio, 1.04; 95% CI, 1.01-1.07, per 1 mu mol/L) remained significantly associated with unfavorable outcomes. In the subgroup analysis based on renal function, tHcy values above the cutoff point (>= 14.60 mu mol/L) showed a close association with the unfavorable outcome only in the normal renal function group (adjusted odds ratio, 3.10; 95% CI, 1.60-6.01). In patients with renal dysfunction, tHcy was not significantly associated with the prognosis of AF-related stroke. Conclusions A higher plasma tHcy level was associated with unfavorable outcomes in patients with AF-related stroke. This positive association may vary according to renal function but needs to be verified in further studies. | Nam, Ki-Woong; Kim, Chi Kyung; Yu, Sungwook; Oh, Kyungmi; Chung, Jong-Won; Bang, Oh Young; Kim, Gyeong-Moon; Jung, Jin-Man; Song, Tae-Jin; Kim, Yong-Jae; Kim, Bum Joon; Heo, Sung Hyuk; Park, Kwang-Yeol; Kim, Jeong-Min; Park, Jong-Ho; Choi, Jay Chol; Park, Man-Seok; Kim, Joon-Tae; Choi, Kang-Ho; Hwang, Yang Ha; Seo, Woo-Keun | Seoul Natl Univ, Dept Neurol, Seoul Metropolitan Govt, Boramae Med Ctr, Seoul, South Korea; Korea Univ, Coll Med, Dept Neurol, Guro Hosp, Seoul, South Korea; Korea Univ, Coll Med, Dept Neurol, Anam Hosp, 73 Goryeodae Ro, Seoul 02841, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Neurol, Sch Med, Seoul, South Korea; Korea Univ, Coll Med, Dept Neurol, Ansan Hosp, Ansan, South Korea; Ewha Womans Univ, Sch Med, Dept Neurol, Seoul, South Korea; Catholic Univ Korea, Dept Neurol, Seoul, South Korea; Asan Med Ctr, Dept Neurol, Seoul, South Korea; Kyung Hee Univ, Dept Neurol, Coll Med, Seoul, South Korea; Chung Ang Univ, Chung Ang Univ Hosp, Dept Neurol, Coll Med, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Neurol, Seoul, South Korea; Hanyang Univ, Myongji Hosp, Dept Neurol, Coll Med, Seoul, South Korea; Jeju Natl Univ, Dept Neurol, Jeju, South Korea; Chonnam Natl Univ Hosp, Dept Neurol, Chungnam, South Korea; Kyungpook Natl Univ Hosp, Dept Neurol, Daegu, South Korea; Sungkyunkwan Univ, Dept Digital Hlth, SHAIST, Seoul, South Korea | ; HWANG, Yang-Ha/F-3068-2013; Jung, Jin-Man/LJL-8037-2024; Kim, Chi/AAR-9819-2020; choi, jo/O-5940-2014; Heo, Sung/P-3529-2019; Kim, Yong-Jae/JQW-5758-2023; Kim, Jeong-Min/ABH-2469-2021; Choi, Kangho/HKV-1503-2023; Kim, Jinkwon/AAR-6729-2021 | 57189377536; 56701057800; 56144716300; 16048029600; 55553751200; 7006620221; 35237139600; 15755814800; 55507164200; 55865497600; 57214661365; 18835720200; 36060099300; 7601375827; 57390600900; 7501392645; 7404490852; 23667663000; 36491173100; 7402311308; 22981667600 | ckkim7@korea.ac.kr;song4yu@korea.ac.kr; | JOURNAL OF THE AMERICAN HEART ASSOCIATION | J AM HEART ASSOC | 2047-9980 | 11 | 9 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS | 2022 | 5.4 | 26.9 | 0.59 | 2025-06-25 | 5 | 5 | atrial fibrillation; homocysteine; ischemic stroke; prognosis; vitamin | SMALL VESSEL DISEASE; SUPPLEMENTAL VITAMINS; B VITAMINS; RISK; PREVENTION; ASSOCIATION; HYPERHOMOCYSTEINEMIA; ATHEROSCLEROSIS; HOMOCYST(E)INE; INFARCTION | atrial fibrillation; homocysteine; ischemic stroke; prognosis; vitamin | Aged; Atrial Fibrillation; Female; Homocysteine; Humans; Ischemic Stroke; Kidney Diseases; Male; Prospective Studies; Risk Factors; Stroke; antivitamin K; C reactive protein; cholesterol; glycosylated hemoglobin; high density lipoprotein; homocysteine; low density lipoprotein; vitamin; vitamin K group; homocysteine; aged; Article; atrial fibrillation; body mass; CHADS2 score; clinical outcome; cohort analysis; diabetes mellitus; diastolic blood pressure; dyslipidemia; echocardiography; estimated glomerular filtration rate; female; human; hypertension; ischemic heart disease; ischemic stroke; kidney dysfunction; leukocyte count; major clinical study; male; National Institutes of Health Stroke Scale; nuclear magnetic resonance imaging; Rankin scale; retrospective study; systolic blood pressure; very elderly; atrial fibrillation; brain ischemia; cerebrovascular accident; complication; kidney disease; prospective study; risk factor | English | 2022 | 2022-05-03 | 10.1161/jaha.121.022138 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Dummy run quality assurance study in the Korean Radiation Oncology Group 19-09 multi-institutional prospective cohort study of breast cancer | Background The Korean Radiation Oncology Group (KROG) 19 - 09 prospective cohort study aims to determine the effect of regional nodal irradiation on regional recurrence rates in ypN0 breast cancer patients. Dosimetric variations between radiotherapy (RT) plans of participating institutions may affect the clinical outcome of the study. We performed this study to assess inter-institutional dosimetric variations by dummy run. Methods Twelve participating institutions created RT plans for four clinical scenarios using computed tomography images of two dummy cases. Based on a reference structure set, we analyzed dose-volume histograms after collecting the RT plans. Results We found variations in dose distribution between institutions, especially in the regional nodal areas. Whole breast and regional nodal irradiation (WBI + RNI) plans had lower inter-institutional agreement and similarity for 95% isodose lines than WBI plans. Fleiss's kappa values, which were used to measure inter-institutional agreement for the 95% isodose lines, were 0.830 and 0.767 for the large and medium breast WBI plans, respectively, and 0.731 and 0.679 for the large and medium breast WBI + RNI plans, respectively. There were outliers in minimum dose delivered to 95% of the structure (D95%) of axillary level 1 among WBI plans and in D95% of the interpectoral region and axillary level 4 among WBI + RNI plans. Conclusion We found inter-institutional and inter-case variations in radiation dose delivered to target volumes and organs at risk. As KROG 19 - 09 is a prospective cohort study, we accepted the dosimetric variation among the different institutions. Actual patient RT plan data should be collected to achieve reliable KROG 19 - 09 study results. | Kim, Myeongsoo; Park, Boram; Kim, Haksoo; Kim, Yeon-Joo; Choi, Dong Ju; Chung, Weonkuu; Kim, Yeon Joo; Shin, Hyun Soo; Im, Jung Ho; Suh, Chang-Ok; Kim, Jin Hee; Ha, Boram; Kim, Mi Young; Park, Jongmoo; Lee, Jeongshim; Ahn, Sung-Ja; Lee, Sun Young; Kusumawidjaja, Grace; Lim, Faye; Cho, Won Kyung; Kim, Haeyoung; Choi, Doo Ho; Park, Won | Natl Canc Ctr, Dept Radiat Oncol, Goyang, South Korea; Samsung Med Ctr, Biomed Stat Ctr, Seoul, South Korea; Kyung Hee Univ, Kyung Hee Univ Hosp Gangdong, Radiat Oncol, Sch Med, Seoul, South Korea; Kangwon Natl Univ Hosp, Dept Radiat Oncol, Chunchon, South Korea; CHA Univ, CHA Bundang Med Ctr, Dept Radiat Oncol, Seongnam, South Korea; Keimyung Univ, Dept Radiat Oncol, Dongsan Med Ctr, Daegu, South Korea; Hallym Univ, Dept Radiat Oncol, Dongtan Sacred Heart Hosp, Hwaseong, South Korea; Kyungpook Natl Univ, Dept Radiat Oncol, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiat Oncol, Daegu, South Korea; Inha Univ Hosp, Dept Radiat Oncol, Incheon, South Korea; Chonnam Natl Univ, Dept Radiat Oncol, Hwasun Hosp, Gwangju, Jeollanam Do, South Korea; Jeonbuk Natl Univ Hosp, Dept Radiat Oncol, Jeonju, South Korea; Natl Canc Ctr Singapore, Div Radiat Oncol, Singapore, Singapore; Sungkyunkwan Univ, Samsung Med Ctr, Dept Radiat Oncol, Sch Med, Seoul, South Korea; Natl Canc Ctr, Proton Therapy Ctr, 323 Ilsan Ro, Goyang Si 410769, Gyeonggi Do, South Korea | Lee, Sun-Ho/AAD-6712-2022; Choi, Dong-Ju/J-5686-2012; Lee, Jong-Young/M-6319-2013; Lim, Eun-Kyung/AAR-8644-2020; Kim, Haeyoung/ABC-4815-2020; Kim, Jae-Young/IUO-6466-2023; Kim, Yong-Joo/AAK-1840-2021; Kim, Juewon/ABH-3314-2020 | 57217085985; 57199829286; 56046894300; 57216357970; 57968404000; 55162531100; 57225867754; 56096038400; 7102970921; 56441016600; 56022514500; 57204652164; 56180048900; 57211862928; 57211944596; 57203597345; 20433913500; 57267673500; 57201979532; 56007004100; 55768286100; 55663053400 | haksoo.kim@ncc.re.kr;yjkim1785@ncc.re.kr; | RADIATION ONCOLOGY | RADIAT ONCOL | 1748-717X | 17 | 1 | SCIE | ONCOLOGY;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2022 | 3.6 | 27.0 | 0 | 2025-06-25 | 0 | 0 | Breast neoplasms; Radiotherapy; Quality assurance; Dummy run; Dosimetric variations | INTERNAL MAMMARY; RADIOTHERAPY; IRRADIATION; MULTICENTER; DELINEATION; AMAROS; NODE | Breast neoplasms; Dosimetric variations; Dummy run; Quality assurance; Radiotherapy | Axilla; Breast Neoplasms; Female; Humans; Prospective Studies; Radiotherapy, Adjuvant; Republic of Korea; Article; body mass; breast cancer; breast radiotherapy; cancer radiotherapy; clinical outcome; cohort analysis; computer assisted tomography; conformal radiotherapy; histogram; human; human tissue; intensity modulated radiation therapy; lymph node biopsy; metastasis; multicenter study; neoadjuvant chemotherapy; organs at risk; radiation dose; radiation dose distribution; radiation oncology; volumetric modulated arc therapy; adjuvant radiotherapy; axilla; breast tumor; female; procedures; prospective study; South Korea | English | 2022 | 2022-11-16 | 10.1186/s13014-022-02140-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Mineralogical and geochemical characteristics of the hydrothermal illite from Hoam granite, South Korea: Implications for episodic fluid injections in the hydrothermal alteration system | Two stages of illite mineralization are recognized in the hydrothermal alteration zone of the Hoam granite. These illites are formed as a result of pervasive alteration by re-equilibration with high water/rock in a brittle environment below 250 degrees C), high fS(2), and a relatively acidic environment. The pseudomorphic replacement combined with matrix-filling texture indicates that the illites at the site-1 alteration zone recorded the changes in fluid conditions from low to high water-rock ratio. In contrast, the illites at the site-2 alteration zone show the coexistence of polytypes (2M(1), 1M, and 1M(d)), high-K illites [(K-0.83 per O-10(OH)(2)]/low-K illites [K-0.63 per O-10(OH)(2)], platy/hairy shapes, and presence of magnetite. Furthermore, this alteration zone no longer exhibits primary textures because of pervasive alteration induced by the dissolution-precipitation process. These results indicate that they were formed in a rapid cooling system and were continuously under conditions of high water-rock ratio, as well as in a less acidic and fS2 environment than that observed at the site-1 alteration zone. The behavior of trace elements for each illite primarily depends on the constituents of the hydrothermal fluid, which reflect different degrees of fluid evolution. The enrichment of high field strength elements (Nb and Ta), large ion lithophile elements (B, Be, and Cs), rare earth elements, and actinide elements (U and Th) in illite at the site-2 alteration zone shows that these elements formed by a more evolved fluid than that of the illite at the site-1 alteration zone. In addition, negative Ce anomalies at the site-2 alteration zone indicate that these crystallized in a reducing environment. Considering the mineralogical and geochemical properties of illites at the site-1 and site-2 alteration zones, the illite mineralization in the Hoam granite was likely generated by at least two episodes of hydrothermal illite mineralization, which originated from episodic injections of fluids, rather than continuously evolved fluids. | Park, Changyun; Chung, Donghoon; Park, Chaewon; Seo, Seungbin; Kim, Jae Hwan; Seo, Sung Man; Kang, Il-Mo | Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Daejeon 34132, South Korea; Yonsei Univ, Dept Earth Syst Sci, Seoul 03722, South Korea | Kang, Il-Mo/A-7441-2010 | 56197393100; 56197258200; 58364103700; 57966903200; 57203324980; 57200273242; 7203062722 | changyun.park@knu.ac.kr;imkang@kigam.re.kr; | GEOCHEMISTRY | GEOCHEMISTRY-GERMANY | 0009-2819 | 1611-5864 | 82 | 4 | SCIE | GEOCHEMISTRY & GEOPHYSICS | 2022 | 3.7 | 27.0 | 0.36 | 2025-06-25 | 2 | 3 | Illite; Hydrothermal alteration; Illite polytype; Trace elements; Granite | EARTH-ELEMENT MOBILITY; TRACE-ELEMENTS; CLAY-MINERALS; HOT-SPRINGS; ORIGIN; QUANTIFICATION; SORPTION; SERICITE; DEPOSITS; ROCKS | Granite; Hydrothermal alteration; Illite; Illite polytype; Trace elements | South Korea; fluid injection; geochemistry; granite; hydrothermal alteration; illite; mineralization; mineralogy; Oligocene; trace element | English | 2022 | 2022-11 | 10.1016/j.chemer.2022.125919 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Flexible Polymer Solar Cells with High Efficiency and Good Mechanical Stability | Single-junction polymer solar cells have demonstrated exceptional power conversion efficiency. Interlayer adhesion will be critical in building flexible polymer solar cells since inorganic conveyance layers would surely break. Aluminium-doped zinc oxide modified by polydopamine has emerged as a viable electron transportation layer in polymer solar cells, enhancing mechanical qualities by offering a high degree of flexibility and adhesion to the active layer. Power conversion efficiency of 12.7% is achieved in nonfullerene polymer solar cells built on PBDB-T2F:IT-4F with aluminium-doped zinc oxide 1.5% polydopamine electron transporting layer. Furthermore, the device based on Ag-mesh wire-wound electrodes has a power conversion efficiency of 11.5% and retains more than 90% of original power conversion efficiency afterward 1500 cycles of bending. For implantable and adaptable polymer solar cells for wide areas, roll-to-roll fabrication of inorganic electron transport layers is advantageous because of their mechanical resilience and thickness insensitivity. | Kathir, I.; Shinde, Santaji Krishna; Parswajinan, C.; Hanumanthakari, Sudheer; Loganathan, K.; Madhavarao, S.; Seikh, A.

| ○ | ○ | Article | Optimal Placement of Hybrid Wind-Solar System Using Deep Learning Model | In this paper, we develop an optimal placement of solar-wind energy systems using restricted Boltzmann machine (RBM). The RBM considers various factors to scale the process of optimal placement and enables proper sizing and placement for attaining increased electricity production from both wind and solar systems. The multiobjective criterion from both solar and wind energy farms simulated on MATLAB simulator shows an increased number of accuracies with reduced mean average error and computation time during training and testing.
