In addition to vitamin D which is well established to have an association with osteoporosis, B vitamins, such as thiamine, folate (vitamin B9), and cobalamin (vitamin B12), could affect bone metabolism, bone quality, and fracture risk in humans by influencing homocysteine/folate metabolism. Despite the crucial role of B vitamins in bone metabolism, there are few studies regarding associations between B vitamin-related genes and osteoporosis. In this study, we investigated the genetic association of four single nucleotide polymorphisms (SNPs) within the 3'-untranslated regions of vitamin B-related genes, includingTCN2(encodes transcobalamin II),CD320(encodes transcobalamin II receptor),SLC19A1(encodes reduced folate carrier protein 1), andSLC19A2(encodes thiamine carrier 1), with osteoporosis and osteoporotic vertebral compression fracture (OVCF). We recruited 301 postmenopausal women and performed genotyping ofCD320 rs9426C>T,TCN2 rs10418C>T,SLC19A1 rs1051296G>T, andSLC19A2 rs16862199C>Tusing a polymerization chain reaction-restriction fragment length polymorphism assay. There was a significantly higher incidence of both osteoporosis (AOR 5.019; 95% CI, 1.533-16.430,p< 0.05) and OVCF (AOR, 5.760; 95% CI, 1.480-22.417,p< 0.05) in individuals with genotypeCD320CT+TT and high homocysteine concentrations. Allele combination analysis revealed that two combinations, namelyCD320C-TCN2T-SLC19A1T-SLC19A2C (OR, 3.244; 95% CI, 1.478-7.120,p< 0.05) andCD320T-TCN2C-SLC19A1G-SLC19A2C (OR, 2.287; 95% CI, 1.094-4.782,p< 0.05), were significantly more frequent among the osteoporosis group. Our findings suggest that SNPs within theCD320gene in 3 '-UTR may contribute to osteoporosis and OVCF occurrences in some individuals. Furthermore, specific allele combinations ofCD320,TCN2,SLC19A1,andSLC19A2may contribute to increased susceptibility to osteoporosis and OVCF. | Ahn, Tae-Keun; Kim, Jung Oh; An, Hui Jeong; Park, Han Sung; Choi, Un Yong; Sohn, Seil; Kim, Kyoung-Tae; Kim, Nam Keun; Han, In-Bo | CHA Univ, CHA Bundang Med Ctr, Dept Orthoped, Seongnam 13496, South Korea; Theragen Bio Co Ltd, 145 Gwanggyo Ro, Suwon 16229, South Korea; CHA Univ, Coll Life Sci, Dept Biomed Sci, Seongnam 13488, South Korea; CHA Univ, CHA Bundang Med Ctr, Dept Neurosurg, Seongnam 13496, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Neurosurg, Daegu 41944, South Korea | Kim, Jung Oh/JDC-5061-2023 | 56540832500; 55902716000; 56825018200; 57195943056; 57209540640; 55047974500; 57201369790; 35074187200; 9338449900 | ajh329@gmail.com;jokim8505@gmail.com;tody2209@naver.com;hahnsung@naver.com;nschoiuy@gmail.com;sisohn@cha.ac.kr;nskimkt7@gmail.com;nkkim@cha.ac.kr;hanib@cha.ac.kr; | GENES | GENES-BASEL | 2073-4425 | 11 | 6 | SCIE | GENETICS & HEREDITY | 2020 | 4.096 | 37.2 | 0.69 | 2025-06-25 | 12 | 14 | cobalamin; folate; homocysteine; polymorphism; osteoporosis; compression fracture | BONE-MINERAL DENSITY; PLASMA HOMOCYSTEINE LEVELS; BODY-MASS INDEX; HIP FRACTURE; RISK; TRANSCOBALAMIN; RECEPTOR; FOLATE; LEVEL; PARAMETERS | Cobalamin; Compression fracture; Folate; Homocysteine; Osteoporosis; Polymorphism | 3' Untranslated Regions; Alleles; Antigens, CD; Female; Folic Acid; Fractures, Compression; Genetic Association Studies; Genetic Predisposition to Disease; Genotype; Humans; Membrane Transport Proteins; Osteoporosis; Osteoporotic Fractures; Postmenopause; Receptors, Cell Surface; Reduced Folate Carrier Protein; Transcobalamins; Vitamin B 12; Vitamin B Complex; homocysteine; transcobalamin II; carrier protein; CD320 protein, human; cell surface receptor; cyanocobalamin; folic acid; leukocyte antigen; reduced folate carrier; SLC19A1 protein, human; SLC19A2 protein, human; TCN2 protein, human; transcobalamin; vitamin B complex; 3' untranslated region; aged; allele; Article; case control study; CD320 gene; compression fracture; controlled study; disease predisposition; female; gene; genetic analysis; genetic association; genotype; human; Korean (people); major clinical study; morbidity; osteoporosis; polymerase chain reaction; postmenopause; restriction fragment length polymorphism; single nucleotide polymorphism; SLC19A1 gene; SLC19A2 gene; spine fracture; TCN2 gene; 3' untranslated region; compression fracture; fragility fracture; genetic association study; genetic predisposition; genetics; metabolism; osteoporosis; pathophysiology | English | 2020 | 2020-06 | 10.3390/genes11060612 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A compact and efficient graphene FET based RF energy harvester for green communication | This paper presents a graphene field effect transistor (FET) based rectenna with substrate-integrated waveguide (SIW) broadband approach for RF energy harvesting application. The proposed structure of integrated rectenna consists of a graphene FET rectifier and an SIW antenna operating in the (S-11 < -10 dB) range of 29-46 GHz. The peak gain of the SIW antenna observed is 8.12 dBi. In addition, a new matched circuit consisting of microstrip line and butterfly stub (without using any lumped elements) is designed. The matched circuit provides a miniaturized block by reducing the size and eliminating parasitic reactance in the integrated rectenna. The proposed rectenna is implemented and fabricated using two superimposed layers: RT/duroid 5880 and graphene substrate with a compatible approach. A measured conversion efficiency of 80.32% is obtained. The dimensions of the proposed antenna and rectifier are 3.2 x 3.2 x 0.4 mm(3) and 3.2 x 10 x 0.4 mm(3), respectively. The proposed rectenna covers Ka- and Q-band applications and could be a potential candidate for contemporary energy harvesting systems. (C) 2019 Elsevier GmbH.

| ○ | ○ | Article | An ultra-compact two-port UWB-MIMO antenna with dual band-notched characteristics | In this paper, an ultra-compact two-port MIMO antenna working in the frequency range of 3.1-10.6 GHz with dual band-notched characteristics is presented. The MIMO antenna consists of two identical octagonal-shaped radiating elements placed adjacent to each other with a connected ground plane. The overall size of the proposed two-port UWB-MIMO antenna is 19 x 30 x 0.8 mm(3). In the ground plane of antenna elements, a T-shaped stub is introduced to create band-notch at 5.5 GHz. Also, an open-ended half-guided-wavelength resonator slot is introduced along the upper edge of the octagonal radiator to obtain a broader notched-band (4.37-5.95 GHz). The second band-notch is created around 7 GHz (6.52-7.45 GHz) by etching another open-ended slot from the radiating patch. The two-notch bands reject interference due to HiperLAN, WiMAX, INSAT/Super-extended C-band, downlink of X-band satellite communication and RFID service bands. A pair of L-shaped slits are introduced in the feed line to improve impedance matching, for the frequency band available between the two notches. The proposed design is fabricated on an FR-4 substrate and minimum isolation greater than 18 dB (a major portion >22 dB) and envelope correlation coefficient (ECC) less than 0.13 are obtained. The antenna gain varies in the range of 1.2-2.91 dBi with a variation of 1.71 dBi only. A radiation efficiency, greater than 70% is achieved throughout the operating frequency band.

| ○ | ○ | Article | Effect of convergent duct geometry on the energy extraction performance of tandem oscillating hydrofoils system | In the present study, a new hydrokinetic energy harvester concept based on the tandem oscillating hydrofoils configuration is numerically investigated. Unsteady turbulent two dimensional flow simulations were performed, by using the commercial finite volume computational fluid dynamics code FLUENT, to study the power extraction from tandem hydrofoils oscillating inside a convergent duct. A sinusoidal function was used to interpret the plunging/pitching motion of NACA 0015 hydrofoil. Computations were carried out for the different configurations of area ratios (AR) that is defined as the ratio of the upstream hydrofoil's inlet cross section (A(1)) to the downstream hydrofoil's inlet cross section (A(2)) ranging from 1.0 (without the convergent section) to AR = 2.6. The study revealed that the power extraction was enhanced by the increased incoming flow velocity enabled by the geometry of the convergent duct, which positively affected the total pressure as well as the hydrofoil-vortex interaction time and resulted the generation of larger vertical hydrodynamic force. Upon analysis of the obtained results, it is found that the energy extraction efficiency is improved, compared to that of the conventional tandem configuration where the hydrofoils move in an open flow space, and, as the area ratio (AR) increased, the amount of extracted power becomes higher in a proportion ranging from 4% to 80%. The concept was numerically tested for tandem and single configurations and for non-dimensional frequencies in the range of f* = 0.04 - 0.20. One interesting finding is that, due to some positive effect of hydrofoil-vortex interaction, and at a specified area ratio and frequency, the downstream hydrofoil efficiency exceeds the efficiency of a single hydrofoil located at exactly same position as the downstream hydrofoil in the tandem configuration. The frequency and the area ratio are found to be critical factors that determine whether the downstream hydrofoil-vortex interaction is favorable or unfavorable. An optimal area ratio frequency combination results in a positive hydrofoil-vortex interaction effect and allows the downstream hydrofoil to contribute positively to the total power extraction as a single hydrofoil. Based on the present results, and for an optimal efficient energy harvester design, a new correlation is suggested in order to properly control the area ratio in accordance with the variation of the oscillating frequency leading to more power production and high performance of the oscillating tandem hydrofoils. It is anticipated that this new innovative technique will be applied to improve the existing energy harvester devices. (C) 2020 Elsevier Ltd. All rights reserved. | Dahmani, F.; Sohn, C.

| ○ | ○ | Article | Expression of the Long Noncoding RNA GAS5 Correlates with Liver Fibrosis in Patients with Nonalcoholic Fatty Liver Disease | Background: Advanced liver fibrosis is the most important prognostic factor in nonalcoholic fatty liver disease (NAFLD). The long noncoding RNA (lncRNA), growth arrest-specific transcript 5 (GAS5), is associated with the inhibition of liver fibrogenesis, and its levels are decreased in cirrhotic liver. Methods: We analyzed 51 patients with NAFLD, the diagnosis of which was confirmed by liver biopsy. Expression of GAS5 in both the liver and plasma of the patients was analyzed using a quantitative real-time polymerase chain reaction according to the fibrosis stage. Results: Plasma GAS5 expression was significantly higher in patients with advanced fibrosis than in those without. As the fibrosis progressed, GAS5 expression in plasma increased, with the exception of that in cirrhotic livers. Plasma levels of GAS5 were lower in patients with cirrhosis than in those with advanced fibrosis. Conclusion: Elevated circulating levels of the lncRNA GAS5 are associated with the progression of liver fibrosis prior to the development of cirrhosis. | Han, Man-Hoon; Lee, Jee Hyun; Kim, Gyeonghwa; Lee, Eunhye; Lee, Yu Rim; Jang, Se Young; Lee, Hye Won; Chun, Jae Min; Han, Young Seok; Yoon, Jun Sik; Kang, Min Kyu; Lee, Won Kee; Kweon, Young Oh; Tak, Won Young; Park, Soo Young; Park, Jung Gil; Hur, Keun | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Pathol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Cell & Matrix Res Inst, Dept Biochem & Cell Biol, Daegu 41944, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, Daegu 41944, South Korea; Keimyung Univ, Dongsan Med Ctr, Sch Med, Dept Pathol, Daegu 42601, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Surg, Daegu 41944, South Korea; Inje Univ, Busan Paik Hosp, Dept Internal Med, Coll Med, Busan 74392, South Korea; Yeungnam Univ, Coll Med, Dept Internal Med, Daegu 42415, South Korea; Kyungpook Natl Univ, Med Res Collaborat Ctr KNUH, Daegu 42415, South Korea; Kyungpook Natl Univ, Sch Med, Daegu 42415, South Korea | ; Hur, Keun/G-9513-2011; Kim, Gyeonghwa/AAQ-6424-2021; Kang, Min Kyu/U-8050-2018; Park, Jung/AAK-5167-2020; Kang, Min/U-8050-2018 | 57194067936; 57216817247; 57195957884; 57189661699; 57194094753; 57202881977; 57907713300; 24773178000; 7404096216; 57195953972; 59142854300; 22953484700; 7004694832; 7004074582; 57191674344; 57216816399; 8861888000 | one-many@hanmail.net;jihyunlee.knu@gmail.com;aoet111@gmail.com;eunhye7832@naver.com;deblue00@naver.com;magnolia1103@naver.com;hoongir182@naver.com;mong0101@dreamwiz.com;gshyskhk@hanmail.net;yojusi@naver.com;kmggood111@naver.com;wonlee@knu.ac.kr;yokweon@knu.ac.kr;wytak@knu.ac.kr;psyoung0419@gmail.com;gsnrs@naver.com;KeunHur@knu.ac.kr; | GENES | GENES-BASEL | 2073-4425 | 11 | 5 | SCIE | GENETICS & HEREDITY | 2020 | 4.096 | 37.2 | 1.99 | 2025-06-25 | 33 | 35 | noncoding RNA; biomarker; lncRNA GAS5; nonalcoholic fatty liver disease; liver fibrosis | CANCER; HOTAIR; LINCRNA-P21; MORTALITY; MECHANISM; DIAGNOSIS; BIOMARKER; FEATURES; CELLS | Biomarker; Liver fibrosis; LncRNA GAS5; Nonalcoholic fatty liver disease; Noncoding RNA | Adult; Disease Progression; Female; Gene Expression Regulation; Humans; Liver; Liver Cirrhosis; Male; Middle Aged; Non-alcoholic Fatty Liver Disease; Real-Time Polymerase Chain Reaction; RNA, Long Noncoding; growth arrest specific transcript 5; long untranslated RNA; unclassified drug; GAS5 long non-coding RNA, human; long untranslated RNA; adult; Article; disease severity; down regulation; female; gene expression; genetic association; human; human tissue; liver biopsy; liver cirrhosis; liver fibrosis; major clinical study; male; nonalcoholic fatty liver; prognosis; protein blood level; protein expression; real time polymerase chain reaction; tissue level; biosynthesis; blood; complication; disease exacerbation; gene expression regulation; genetics; liver; liver cirrhosis; metabolism; middle aged; nonalcoholic fatty liver; pathology | English | 2020 | 2020-05 | 10.3390/genes11050545 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Human resources required for antimicrobial stewardship activities for hospitalized patients in Korea | Objectives: We calculated the human resources required for an antimicrobial stewardship program (ASP) in Korean hospitals. Design: Multicenter retrospective study. Setting: Eight Korean hospitals ranging in size from 295 to 1,337 beds. Methods: The time required for performing ASP activities for all hospitalized patients under antibiotic therapy was estimated and converted into hours per week. The actual time spent on patient reviews of each ASP activity was measured with a small number of cases, then the total time was estimated by applying the determined times to a larger number of cases. Full-time equivalents (FTEs) were measured according to labor laws in Korea (52 hours per week). Results: In total, 225 cases were reviewed to measure time spent on patient reviews. The median time spent per patient review for ASP activities ranged from 10 to 16 minutes. The total time spent on the review for all hospitalized patients was estimated using the observed number of ASP activities for 1,534 patients who underwent antibiotic therapy on surveillance days. The most commonly observed ASP activity was 'review of surgical prophylactic antibiotics' (32.7%), followed by 'appropriate antibiotics recommendations for patients with suspected infection without a proven site of infection but without causative pathogens' (28.6%). The personnel requirement was calculated as 1.20 FTEs (interquartile range [IQR], 1.02-1.38) per 100 beds and 2.28 FTEs (IQR, 1.93-2.62) per 100 patients who underwent antibiotic therapy, respectively. Conclusion: The estimated time required for human resources performing extensive ASP activities on all hospitalized patients undergoing antibiotic therapy in Korean hospitals was similar to 1.20 FTEs (IQR, 1.02-1.38) per 100 beds. | Park, Se Yoon; Chang, Hyun-Ha; Kim, Bongyoung; Moon, Chisook; Lee, Mi Suk; Kim, Jin Yong; Jung, Dong Sik; Kim, Shin-Woo; Moon, Song Mi; Kim, Eu Suk; Kim, Hong Bin | Soonchunhyang Univ, Dept Internal Med, Div Infect Dis, Seoul Hosp,Coll Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Div Infect Dis, Daegu, South Korea; Hanyang Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Inje Univ, Dept Internal Med, Busan Paik Hosp, Div Infect Dis, Busan, South Korea; Kyung Hee Univ, Sch Med, Dept Internal Med, Div Infect Dis, Seoul, South Korea; Incheon Med Ctr, Dept Internal Med, Div Infect Dis, Incheon, South Korea; Dong A Univ, Coll Med, Dept Internal Med, Div Infect Dis, Busan, South Korea; Hallym Univ, Sacred Heart Hosp, Div Infect Dis, Dept Internal Med, Anyang, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Internal Med, Div Infect Dis,Coll Med, Seoul, South Korea | Kim, Ik-Sang/J-5425-2012; Kim, Woo/AAG-1822-2019; Kim, Jung/L-9791-2019; Kim, Hee/AAU-6368-2021; Jung, Dong Sik/HOH-5826-2023; Kim, Hong Bin/J-5452-2012; Kim, Eu/J-5424-2012 | 55259986400; 7407521688; 55622077200; 22980995800; 55759244100; 57211142178; 14023089600; 8710731500; 36554757200; 22938086900; 35307429400 | sobakas@hanyang.ac.kr;eskim@snubh.org; | INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY | INFECT CONT HOSP EP | 0899-823X | 1559-6834 | 41 | 12 | SCIE | INFECTIOUS DISEASES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2020 | 3.254 | 37.2 | 1.03 | 2025-06-25 | 22 | 21 | PROGRAMS | Anti-Bacterial Agents; Antimicrobial Stewardship; Hospitals; Humans; Republic of Korea; Retrospective Studies; Workforce; antibiotic agent; antiinfective agent; adult; antibiotic therapy; antimicrobial stewardship; Article; controlled study; data analysis software; female; health workforce; hospital patient; human; infection; infection prevention; Korea; major clinical study; male; middle aged; multicenter study (topic); practice guideline; retrospective study; time factor; clinical trial; hospital; multicenter study; South Korea | English | 2020 | 2020-12 | 10.1017/ice.2020.1234 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Hybrid beam selection scheme in millimeter-wave beamspace MIMO-NOMA with lens antenna array | Beam selection is a notable issue for recent wireless communications. A conventional single beam selection (SBS) concept is utilized to minimize the number of necessary radio frequency chains in millimeter-wave (mmWave) multiple-input multiple-output non-orthogonal multiple access (MIMO-NOMA) systems. In general, the traditional SBS concept cannot implement a multiple beam group selection opportunity for every supported user. In this circumstance, the user side spends too much computational burden to measure the decoded message and suffer a beam optimization problem. Therefore, we propose a hybrid beam selection (HBS) scheme to utilize a multiple SBS scheme in beamspace MIMO-NOMA systems. Consequently, each supported user can easily achieve a low beam optimization problem by selecting a reliable SBS group from the proposed HBS scheme and significantly increase the spectral performance. Furthermore, we demonstrate an iterative beam power maximization algorithm utilizing the HBS scheme to solve the power allocation problem in this paper. The numerical results are verified by computer simulations in terms of a downlink beamspace MIMO-NOMA channel with a lens antenna array environment. (C) 2020 Elsevier GmbH.

| ○ | ○ | Article | Magnetic resonance imaging features of tumor and lymph node to predict clinical outcome in node-positive cervical cancer: a retrospective analysis | Background Current chemoradiation regimens for locally advanced cervical cancer are fairly uniform despite a profound diversity of treatment response and recurrence patterns. The wide range of treatment responses and prognoses to standardized concurrent chemoradiation highlights the need for a reliable tool to predict treatment outcomes. We investigated pretreatment magnetic resonance (MR) imaging features of primary tumor and involved lymph node for predicting clinical outcome in cervical cancer patients. Methods We included 93 node-positive cervical cancer patients treated with definitive chemoradiotherapy at our institution between 2006 and 2017. The median follow-up period was 38 months (range, 5-128). Primary tumor and involved lymph node were manually segmented on axial gadolinium-enhanced T1-weighted images as well as T2-weighted images and saved as 3-dimensional regions of interest (ROI). After the segmentation, imaging features related to histogram, shape, and texture were extracted from each ROI. Using these features, random survival forest (RSF) models were built to predict local control (LC), regional control (RC), distant metastasis-free survival (DMFS), and overall survival (OS) in the training dataset (n = 62). The generated models were then tested in the validation dataset (n = 31). Results For predicting LC, models generated from primary tumor imaging features showed better predictive performance (C-index, 0.72) than those from lymph node features (C-index, 0.62). In contrast, models from lymph nodes showed superior performance for predicting RC, DMFS, and OS compared to models of the primary tumor. According to the 3-year time-dependent receiver operating characteristic analysis of LC, RC, DMFS, and OS prediction, the respective area under the curve values for the predicted risk of the models generated from the training dataset were 0.634, 0.796, 0.733, and 0.749 in the validation dataset. Conclusions Our results suggest that tumor and lymph node imaging features may play complementary roles for predicting clinical outcomes in node-positive cervical cancer. | Park, Shin-Hyung; Hahm, Myong Hun; Bae, Bong Kyung; Chong, Gun Oh; Jeong, Shin Young; Na, Sungdae; Jeong, Sungmoon; Kim, Jae-Chul | Kyungpook Natl Univ, Sch Med, Dept Radiat Oncol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Obstet & Gynecol, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Obstet & Gynecol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Mol Diagnost & Imaging Ctr, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Nucl Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Biomed Engn Ctr, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Biomed Res Inst, Daegu, South Korea; Kyungpook Natl Univ Hosp, Ctr Artificial Intelligence Med, Daegu, South Korea | ; Park, Shinhyung/LNQ-6428-2024 | 57203275843; 56015548700; 57191481610; 23099068000; 36164032500; 56366244500; 23100090400; 55719981700 | shinhyungpark@knu.ac.kr; | RADIATION ONCOLOGY | RADIAT ONCOL | 1748-717X | 15 | 1 | SCIE | ONCOLOGY;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2020 | 3.481 | 37.2 | 1.65 | 2025-06-25 | 25 | 25 | Cervical cancer; Lymph node; Chemoradiotherapy; Predictive modeling; Texture analysis; Radiomics | SURVIVAL; RADIATION; CHEMOTHERAPY; RADIOTHERAPY; IRRADIATION; MANAGEMENT; RADIOMICS; CISPLATIN; BOOST | Cervical cancer; Chemoradiotherapy; Lymph node; Predictive modeling; Radiomics; Texture analysis | Adult; Aged; Aged, 80 and over; Chemoradiotherapy; Female; Humans; Lymph Nodes; Magnetic Resonance Imaging; Middle Aged; Models, Theoretical; Prognosis; Radiographic Image Interpretation, Computer-Assisted; Retrospective Studies; ROC Curve; Treatment Outcome; Uterine Cervical Neoplasms; Young Adult; cisplatin; gadodiamide; gadolinium; adult; aged; Article; cancer chemotherapy; cancer control; cancer patient; cancer radiotherapy; cancer survival; chemoradiotherapy; clinical outcome; contrast enhancement; controlled study; data base; diagnostic test accuracy study; distant metastasis free survival; female; follow up; histogram; human; human tissue; image display; image segmentation; lymph node metastasis; major clinical study; nuclear magnetic resonance imaging; outcome assessment; overall survival; prediction; primary tumor; random forest; receiver operating characteristic; reference value; retrospective study; three-dimensional imaging; uterine cervix cancer; validation study; computer assisted diagnosis; diagnostic imaging; lymph node; middle aged; pathology; prognosis; theoretical model; treatment outcome; uterine cervix tumor; very elderly; young adult | English | 2020 | 2020-04-20 | 10.1186/s13014-020-01502-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Plastome Characterization and Phylogenomics of East Asian Beeches with a Special Emphasis on Fagus multinervis on Ulleung Island, Korea | Beech trees of the genus Fagus (Fagaceae) are monoecious and distributed in the Northern Hemisphere. They represent an important component of mixed broad-leaved evergreen-deciduous forests and are an economically important source of timber. Despite their ecological and economical importance, however, little is known regarding the overall plastome evolution among Fagus species in East Asia. In particular, the taxonomic position and status of F. multinervis, a beech species endemic to Ulleung Island of Korea, remains unclear even today. Therefore, in this study, we characterized four newly completed plastomes of East Asian Fagus species (one accession each of F. crenata and F. multinervis and two accessions of F. japonica). Moreover, we performed phylogenomic analyses comparing these four plastomes with F. sylvatica (European beech) plastome. The four plastomes were highly conserved, and their size ranged from 158,163 to 158,348 base pair (bp). The overall GC content was 37.1%, and the sequence similarity ranged from 99.8% to 99.99%. Codon usage patterns were similar among species, and 7 of 77 common protein-coding genes were under positive selection. Furthermore, we identified five highly variable hotspot regions of the Fagus plastomes (ccsA/ndhD, ndhD/psaC, ndhF/rpl32, trnS-GCU/trnG-UCC, and ycf1). Phylogenetic analysis revealed the monophyly of Fagus as well as early divergence of the subgenus Fagus and monophyletic Engleriana. Finally, phylogenetic results supported the taxonomic distinction of F. multinervis from its close relatives F. engleriana and F. japonica. However, the sister species and geographic origin of F. multinervis on Ulleung Island could not be determined. | Yang, JiYoung; Takayama, Koji; Youn, Jin-Suk; Pak, Jae-Hong; Kim, Seung-Chul | Kyungpook Natl Univ, Sch Life Sci, Dept Biol, Res Inst Dok Do & Ulleung Do Isl, 80 Daehak Ro, Daegu 41566, South Korea; Kyoto Univ, Grad Sch Sci, Dept Bot, Sakyo Ku, Oiwake Cho, Kyoto 6068502, Japan; Sungkyunkwan Univ, Dept Biol Sci, 2066 Seobu Ro, Suwon 16419, South Korea | ; Kim, Seung-Chul/AAR-6157-2020 | 55193226000; 8242260200; 57210840807; 7102232932; 57214983739 | whity@daum.net;takayama.koji.3x@kyoto-u.ac.jp;okita0522@naver.com;jhpak@knu.ac.kr;sonchus96@skku.edu; | GENES | GENES-BASEL | 2073-4425 | 11 | 11 | SCIE | GENETICS & HEREDITY | 2020 | 4.096 | 37.2 | 0.92 | 2025-06-25 | 20 | 19 | plastome; eastern asia beeches; Fagus multinervis; Ulleung Island; Fagaceae | COMPLETE CHLOROPLAST GENOME; PHYLOGENETIC ANALYSIS; NAKAI FAGACEAE; GENE-TRANSFER; SEQUENCE; DNA; EVOLUTION; PHYLOGEOGRAPHY; GENERATION; SELECTION | Eastern asia beeches; Fagaceae; Fagus multinervis; Plastome; Ulleung Island | DNA, Chloroplast; Fagaceae; Fagus; Genome Size; Genome, Plant; Islands; Phylogeny; Plastids; Republic of Korea; chloroplast DNA; article; beech; codon usage; DNA base composition; female; geographic origin; human; island (geological); Korea; monophyly; nonhuman; phylogenomics; relative; beech; Fagaceae; genetics; genome size; phylogeny; plant genome; plastid; South Korea | English | 2020 | 2020-11 | 10.3390/genes11111338 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The velvet Regulator VosA Governs Survival and Secondary Metabolism of Sexual Spores in Aspergillus nidulans | The velvet regulator VosA plays a pivotal role in asexual sporulation in the model filamentous fungus Aspergillus nidulans. In the present study, we characterize the roles of VosA in sexual spores (ascospores) in A. nidulans. During ascospore maturation, the deletion of vosA causes a rapid decrease in spore viability. The absence of vosA also results in a lack of trehalose biogenesis and decreased tolerance of ascospores to thermal and oxidative stresses. RNA-seq-based genome-wide expression analysis demonstrated that the loss of vosA leads to elevated expression of sterigmatocystin (ST) biosynthetic genes and a slight increase in ST production in ascospores. Moreover, the deletion of vosA causes upregulation of additional gene clusters associated with the biosynthesis of other secondary metabolites, including asperthecin, microperfuranone, and monodictyphenone. On the other hand, the lack of vosA results in the downregulation of various genes involved in primary metabolism. In addition, vosA deletion alters mRNA levels of genes associated with the cell wall integrity and trehalose biosynthesis. Overall, these results demonstrate that the velvet regulator VosA plays a key role in the maturation and the cellular and metabolic integrity of sexual spores in A. nidulans. | Kim, Min-Ju; Lee, Mi-Kyung; Pham, Huy Quang; Gu, Myeong Ju; Zhu, Bohan; Son, Sung-Hun; Hahn, Dongyup; Shin, Jae-Ho; Yu, Jae-Hyuk; Park, Hee-Soo; Han, Kap-Hoon | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; KRIBB, BRC, Jeongeup Si 56212, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Woosuk Univ, Dept Pharmaceut Engn, Wonju 55338, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Univ Wisconsin, Dept Bacteriol, Madison, WI 53706 USA; Univ Wisconsin, Dept Genet, Madison, WI 53706 USA; Konkuk Univ, Dept Syst Biotechnol, Seoul 05029, South Korea | Kim, Min-Ju/NGS-6870-2025; Pham, Quang/AAB-3064-2022; Yu, Jae-Hyuk/A-2343-2008; Park, Hee-Soo/AAC-6422-2019; shin, Jaeho/K-6792-2013 | 57204454148; 57221217721; 57200503445; 57208906777; 57206661654; 57214091244; 36554163400; 57224125922; 7405531243; 15751448400; 22947495900 | 13mjkim@gmail.com;miklee1010@kribb.re.kr;bongbimit@gmail.com;myungju1260@naver.com;allen9055@163.com;rk05555@naver.com;dohahn@knu.ac.kr;jhshin@knu.ac.kr;jyu1@wisc.edu;phsoo97@knu.ac.kr;khhan@woosuk.ac.kr; | GENES | GENES-BASEL | 2073-4425 | 11 | 1 | SCIE | GENETICS & HEREDITY | 2020 | 4.096 | 37.2 | 0.92 | 2025-06-25 | 19 | 17 | VosA; sexual development; ascospores; Aspergillus nidulans | TRANSCRIPTION FACTOR; ASEXUAL SPORULATION; GENE; TREHALOSE; INSIGHTS; RESOURCE; FUNGI; NSDD | Ascospores; Aspergillus nidulans; Sexual development; VosA | Aspergillus nidulans; Fungal Proteins; Reproduction, Asexual; Secondary Metabolism; Spores, Fungal; Sterigmatocystin; asperthecin; fungal protein; messenger RNA; microperfuranone; monodictyphenone; regulator protein; RNA; sterigmatocystin; trehalose; unclassified drug; VosA protein; fungal protein; sterigmatocystin; Article; ascospore; Aspergillus nidulans; biogenesis; controlled study; down regulation; fungal cell wall; fungal viability; gene deletion; gene expression; nonhuman; oxidative stress; protein function; protein synthesis; RNA sequence; secondary metabolism; sexual spore; sporogenesis; temperature stress; asexual reproduction; Aspergillus nidulans; biosynthesis; fungus spore; genetics; metabolism; physiology; secondary metabolism | English | 2020 | 2020-01 | 10.3390/genes11010103 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Application of k-ε turbulence models with density corrections to variable density jets under subcritical/supercritical conditions | A density correction method is presented for improving the performance of turbulence models for variable-density jets under subcritical and supercritical conditions. The functional relationship between density and turbulence variables was obtained by considering the logarithmic layer and local equilibrium conditions and the basic form of the relationship was discussed with the large-eddy simulation results. The modified eddy viscosity and a source term of the -equation were introduced in four models, and the modified models were tested for helium, air, and carbon dioxide jets in the presence of co-flowing air. The velocity and density fields of the density-corrected models were in good agreement with the experiment. Cryogenic nitrogen jets under near-critical and supercritical pressures were selected for examining the applicability of the models to the variable density flow with heat transfer. The high velocity decay rates of the original models were found to be considerably reduced in the modified models. The effect of density correction was consistent among the four models with wall function and near-wall treatment. | Park, Tae Seon | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | 7401801892 | tsparkjp@knu.ac.kr; | NUMERICAL HEAT TRANSFER PART A-APPLICATIONS | NUMER HEAT TR A-APPL | 1040-7782 | 1521-0634 | 77 | 2 | SCIE | MECHANICS;THERMODYNAMICS | 2020 | 2.928 | 37.4 | 0.43 | 2025-06-25 | 5 | 5 | LARGE-EDDY SIMULATION; TIME-INTEGRATION METHOD; PISO ALGORITHM; FLOW | Carbon dioxide; Decay (organic); Heat transfer; Wall function; Density correction; Functional relationship; K-epsilon turbulence model; Logarithmic layers; Near-wall treatment; Super-critical pressures; Supercritical condition; Variable-density flows; Large eddy simulation | English | 2020 | 2020-01-17 | 10.1080/10407782.2019.1685817 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Site selection and characterization for onshore 10,000-ton-class CO2 pilot storage in Early Miocene Janggi Basin, SE Korea: Storage potential and structural stability of siliciclastic-volcaniclastic storage combination | This paper presents the results of site selection and characterization for onshore 10,000-ton-class CO2 pilot storage in the Miocene Janggi Basin, SE Korea. The results were obtained from an integrated analysis of geological, geophysical, and geotechnical data, and indicated that Noeseongsan Subbasin is filled by >1-km-thick terrestrial sediments with dacitic to basaltic volcanic materials. Promising storage units are coarse siliciclastic sediments intercalated with mudstones in the lowermost Janggi Conlomerate, exhibiting suitable reservoircaprock association for CO2 injection. The overlying Seongdongri Formation is composed of laterally extensive dacitic tuffs and fine-dominated tuffaceous sediments, forming a regional seal. The storage combination is characterized by a doubly sealed stratigraphic trap, and is laterally confined by juxtaposed seals formed by syndepositional normal fault sets. By considering the stratigraphic and structural features, the conglomerate and sandstone bodies at the boreholes JG-6 (940-971 m) and JG-7-1 (946-970 m) were selected as the optimal site for CO2 storage. It is expected that the stratigraphic and structural traps at the selected site minimize the leakage risk of injected CO2 due to the scarcity of surface and subsurface fractures, low fault intensity, and limited vertical extents of buried faults. The present study reveals that if multidisciplinary approaches involving careful synthesis of the basin were performed, an adequate storage site also can be obtained in this type of small-scale ancient sedimentary basin bearing abundant volcanic materials. | Kim, Min-Cheol; Gihm, Yong Sik; Jeong, Rae-Yoon; Shinn, Young Jae; Son, Moon | Pusan Natl Univ, Dept Geol Sci, Busan 46241, South Korea; Kyungpook Natl Univ, Dept Geol Major Geol, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Petr & Marine Resources Div, Daejeon, South Korea | 59445382700; 56025805300; 57219378763; 6504057732; 8769215000 | moonson@pusan.ac.kr; | INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL | INT J GREENH GAS CON | 1750-5836 | 1878-0148 | 103 | SCIE | ENERGY & FUELS;ENGINEERING, CHEMICAL;ENGINEERING, ENVIRONMENTAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.738 | 37.4 | 0.48 | 2025-06-25 | 12 | 14 | Onshore CO2 storage; Site selection and characterization; Geological storage potential; Miocene Janggi Basin; Volcaniclastic and siliciclastic storage units; South Korea | FAULT ZONE; POHANG BASIN; GEOLOGICAL STORAGE; SOUTHERN KOREA; FLUID-FLOW; LOWER PART; JAPAN SEA; EVOLUTION; HISTORY; ROCKS | Geological storage potential; Miocene Janggi Basin; Onshore CO<sub>2</sub> storage; Site selection and characterization; South Korea; Volcaniclastic and siliciclastic storage units | South Korea; Carbon dioxide; Digital storage; Seals; Sediments; Site selection; Stability; Stratigraphy; Volcanoes; Integrated analysis; Multi-disciplinary approach; Siliciclastic sediments; Structural feature; Structural stabilities; Sub-surface fractures; Terrestrial sediments; Volcanic materials; carbon dioxide; carbon storage; Miocene; siliciclastic deposit; site characterization; site selection; stability analysis; volcaniclastic deposit; Storage (materials) | English | 2020 | 2020-12 | 10.1016/j.ijggc.2020.103174 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Turbulent flow characteristics for enhanced thermal mixing in square and triangular jets | In this study, turbulent flows and the associated mixing characteristics are numerically investigated for noncircular jets. The selected nozzle shapes are round, square, and equilateral triangular, and a passive scalar is adopted to quantify the flow mixing. To achieve a constant mass flow rate, the same cross-sectional area is maintained, and the Reynolds stress model (RSM) is applied to show the turbulence-driven secondary flows. For Re = 21,000, the flow fields of noncircular jets are compared to those of the round jet. After 5 < x/D-e < 10, the half-widths of the round, square, and triangular jets increase linearly. This self-similar structure of the jet flow is rapidly developed for the noncircular jets. Compared to that for the round jet, the spreading rate for square jet increases by 20% and 27% for the triangular jet. From the mixedness values, the mixing is estimated to be enhanced by 16.7% for the square jet and 22.9% for the triangular jet. To elucidate the flow characteristics related to this feature, the scatter plots and streamlines of the secondary flows, vorticity transport equation, and anisotropy-invariant map are discussed. From the results, a balanced relationship between the entrained flow of ambient fluid and the outward spreading flow is observed, and the related turbulence structure is confirmed. | Kim, Won Hyun; Park, Tae Seon | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea | 55360608000; 7401801892 | tsparkjp@knu.ac.kr; | NUMERICAL HEAT TRANSFER PART A-APPLICATIONS | NUMER HEAT TR A-APPL | 1040-7782 | 1521-0634 | 79 | 5 | SCIE | MECHANICS;THERMODYNAMICS | 2020 | 2.928 | 37.4 | 0.11 | 2025-06-25 | 1 | 1 | NUMERICAL-SIMULATION; VARIABLE-DENSITY | Pipe flow; Reynolds number; Secondary flow; Turbulence; Turbulent flow; Anisotropy invariant map; Cross sectional area; Flow charac-teristics; Mixing characteristics; Reynolds stress models; Turbulence structures; Turbulence-driven secondary flows; Vorticity transport equations; Mixing | English | 2020 | 2020-11-09 | 10.1080/10407782.2020.1846452 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | External electric field effect on electronic properties and charge transfer in CoI2/NiI2 spinterface | Electronic structure and spin-related properties of CoI2/NiI2 heterostructure were studied by means of density functional theory. It was shown that the electronic structure at the Fermi level can be characterized by a band gap. The effect of the external electric field on charge transfer and electronic properties of the CoI2/NiI2 interface was investigated, and it was found that band gap width depends on the strength of the applied electric field, switching its nature from semiconducting to a half-metallic one. An easy control of the electronic properties and promising spin-polarized nature of the CoI2/NiI2 spinterface allows the heterostructure to be used in spin-related applications. | Melchakova, Iuliia; Kovaleva, Evgenia A.; Mikhaleva, Natalia S.; Tomilin, Felix N.; Ovchinnikov, Sergey G.; Kuzubov, Alexander A.; Avramov, Paul | Siberian Fed Univ, Krasnoyarsk, Russia; Kirensky Inst Phys, Krasnoyarsk, Russia; Kyungpook Natl Univ, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea | Kovaleva, Evgenia/L-5915-2017; Tomilin, Felix/F-3763-2014; Melchakova, Iuliia/KGM-5967-2024 | 57206720228; 56347793800; 57211669384; 6602246772; 14122071800; 6701337613; 7004322420 | iuliia.melchakova@gmail.com; | INTERNATIONAL JOURNAL OF QUANTUM CHEMISTRY | INT J QUANTUM CHEM | 0020-7608 | 1097-461X | 120 | 3 | SCIE | CHEMISTRY, PHYSICAL;MATHEMATICS, INTERDISCIPLINARY APPLICATIONS;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL;QUANTUM SCIENCE & TECHNOLOGY | 2020 | 2.444 | 37.5 | 0.1 | 2025-06-25 | 5 | 4 | DFT; electric field; Hubbard correction; spintronics; transition metal dihalides | MAGNETIC-PROPERTIES; METAL; EDGE | DFT; electric field; Hubbard correction; spintronics; transition metal dihalides | Charge transfer; Density functional theory; Electric fields; Electronic properties; Electronic structure; Energy gap; Spintronics; Transition metals; Band gap width; Dihalides; External electric field; External electric-field effect; Half-metallic; Hubbard; Spin-polarized; Electric field effects | English | 2020 | 2020-02-05 | 10.1002/qua.26092 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
