| ○ | ○ | Article | Species identification, antibiotic resistance, and virulence in Enterobacter cloacae complex clinical isolates from South Korea | This study aimed to identify the species of Enterobacter cloacae complex (ECC) isolates and compare the genotype, antibiotic resistance, and virulence among them. A total of 183 ECC isolates were collected from patients in eight hospitals in South Korea. Based on partial sequences of hsp60 and phylogenetic analysis, all ECC isolates were identified as nine species and six subspecies. Enterobacter hormaechei was the predominant species (47.0%), followed by Enterobacter kobei, Enterobacter asburiae, Enterobacter ludiwigii, and Enterobacter roggenkampii. Multilocus sequence typing analysis revealed that dissemination was not limited to a few clones, but E. hormaechei subsp. xiangfangensis, E. hormaechei subsp. steigerwaltii, and E. ludwigii formed large clonal complexes. Antibiotic resistance rates were different between the ECC species. In particular, E. asburiae, E. kobei, E. roggenkampii, and E. cloacae isolates were highly resistant to colistin, whereas most E. hormaechei and E. ludwigii isolates were susceptible to colistin. Virulence was evaluated through serum bactericidal assay and the Galleria mellonella larvae infection model. Consistency in the results between the serum resistance and the G. mellonella larvae infection assay was observed. Serum bactericidal assay showed that E. hormaechei, E. kobei, and E. ludwigii were significantly more virulent than E. asburiae and E. roggenkampii. In this study, we identified the predominant ECC species in South Korea and observed the differences in antibiotic resistance and virulence between the species. Our findings suggest that correct species identification, as well as continuous monitoring is crucial in clinical settings. | Ganbold, Michidmaral; Seo, Jungyu; Wi, Yu Mi; Kwon, Ki Tae; Ko, Kwan Soo | Sungkyunkwan Univ, Dept Microbiol, Sch Med, Suwon, South Korea; Sungkyunkwan Univ, Samsung Changwon Hosp, Div Infect Dis, Sch Med, Chang Won, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea | ; Hwang, Soyoon/HHM-5762-2022 | 58077267100; 57203130461; 23013143100; 9733850500; 7202689224 | ksko@skku.edu; | FRONTIERS IN MICROBIOLOGY | FRONT MICROBIOL | 1664-302X | 14 | SCIE | MICROBIOLOGY | 2023 | 4 | 32.6 | 3.1 | 2025-06-25 | 18 | 21 | Enterobacter cloacae complex; Enterobacter hormaechei; virulence; antibiotic resistance; species identification | PATHOGENS; OUTBREAK | antibiotic resistance; Enterobacter cloacae complex; Enterobacter hormaechei; species identification; virulence | aztreonam; cefepime; ceftazidime; chaperonin 60; ciprofloxacin; colistin; cotrimoxazole; gentamicin; imipenem; meropenem; piperacillin plus tazobactam; tigecycline; allele; animal experiment; animal model; antibiotic resistance; Article; bacterial gene; bacterial virulence; bacterium identification; bacterium isolate; broth dilution; colony forming unit; controlled study; dnaA gene; Enterobacter; Enterobacter ludiwigii; Enterobacter roggenkampii; Enterobacter asburiae; Enterobacter bugandensis; Enterobacter chengduensis; Enterobacter cloacae; Enterobacter hormaechei; Enterobacter hormaechei subsp xiangfangensis; Enterobacter kobei; Enterobacter mori; Enterobacter roggenkampii; fusA gene; Galleria mellonella; genotype; genotyping; gyrB gene; larva; leuS gene; multilocus sequence typing; nonhuman; phylogenetic tree; pyrG gene; rplB gene; rpoB gene; sequence analysis; serum bactericidal antibody assay; South Korea; species identification | English | 2023 | 2023-03-23 | 10.3389/fmicb.2023.1122691 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Transient receptor potential ankyrin 1 (TRPA1) and transient receptor potential melastatin 8 (TRPM8) in human odontoblast-like cells participate in lipopolysaccharide-induced immune response | Objectives: To investigate whether transient receptor potential ankyrin 1 (TRPA1) and transient receptor potential melastatin 8 (TRPM8) have a function in responding to environmental stimuli in human odontoblast-like cells (hOLCs). Additionally, to explore whether activation of TRPA1 and TRPM8 in hOLCs participates in the regulation of the inflammatory process.Design: Changes in gene and protein expression levels of TRPA1 and TRPM8 in cultured hOLCs following lipo-polysaccharide (LPS) stimulation, which mimics inflammation, were examined using quantitative reverse transcription-polymerase chain reaction and western blot analysis. Furthermore, we compared the expression profiles of 80 cytokines between LPS-and vehicle-treated hOLCs and investigated how the production of highly increased cytokines in LPS-treated hOLCs was affected by the pharmacological inhibition of TRPA1 and TRPM8.Results: The expression of TRPA1 and TRPM8 in hOLCs was observed and their mRNAs and proteins were upregulated in hOLCs after LPS treatment. Moreover, cytokine antibody assays revealed that monocyte chemoattractant protein-1 (MCP-1, CCL2), growth-regulated protein & alpha; (GRO & alpha;, CXCL1), interleukin-6 (IL-6), and IL-8 (CXCL8) were significantly upregulated by LPS. The pharmacological inhibition of TRPA1 (HC-030031) during LPS treatment attenuated the expression of CCL2, CXCL1, and IL-8, whereas the pharmacological inhibition of TRPM8 (PF05105679) suppressed the expression of CCL2, CXCL1, and IL-8 as well as IL-6. Conclusions: These results indicate that hOLCs express TRPA1 and TRPM8, which are upregulated during inflammation. In addition to being sensors of potentially harmful stimuli, TRPA1 and TRPM8 in hOLCs play important roles in regulating inflammatory responses. | Kim, Yun Sook; Otgonsuren, Munkh-Ochir | Kyungpook Natl Univ, Sch Dent, Dept Anat & Neurobiol, Daegu, South Korea | 23037541600; 58564349000 | yunskim@knu.ac.kr; | ARCHIVES OF ORAL BIOLOGY | ARCH ORAL BIOL | 0003-9969 | 1879-1506 | 155 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2023 | 2.2 | 32.6 | 0.25 | 2025-06-25 | 1 | 1 | Odontoblast; TRPA1; TRPM8; CCL2; CXCL1; IL-6; IL-8; Inflammation | EXPRESSION; ACTIVATION; INFLAMMATION; NEURONS | CCL2; CXCL1; IL-6; IL-8; Inflammation; Odontoblast; TRPA1; TRPM8 | English | 2023 | 2023-11 | 10.1016/j.archoralbio.2023.105800 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Interrelation between ferroelectric properties and defects based on low-frequency noise analysis of HZO ferroelectric capacitor | Switching characteristics of ferroelectrics depend on the fabrication conditions and phase-transition results of each fabrication recipe. Here, the pulsed I-V and positive-up negative-down plots of hafnium zirconium oxide ferroelectric capacitors (FeCaps) are analyzed using low-frequency noise (LFN), an electrical method to investigate defects including oxygen vacancies that are key elements influencing polarization properties. This is a new trial at adopting the LFN method for analysis of FeCaps to find interrelation ferroelectric characteristics and defects depending on the annealing conditions. Increasing power spectral density (PSD) levels are observed with increasing annealing temperature and time. Moreover, the nature of the defects reflected in the PSD is examined via x-ray photoelectron spectroscopy. Correlations are observed between the defects, including oxygen vacancies and ZrOx defects, and FeCap properties. High intrinsic polarization is observed when the density of defects is large; this shows that oxygen vacancies and ZrOx defects in FeCaps may enhance the orthorhombic phase by inducing lattice strain. These findings are expected to facilitate LFN studies of ferroelectrics and the fundamental understanding of their electrical properties from defects and oxygen vacancy analyses. | Jin, Seunghee; Jeon, Juye; Kim, Min Jung; Heo, Kiseok; Kim, Jeong Hun; Im, Jong-Pil; Yoon, Sung-Min; Moon, Seung Eon; Woo, Jiyong; Lee, Jae Woo | Korea Univ, Dept Elect & Informat Engn, 2511 Sejong Ro, Sejong 30019, South Korea; Samsung Elect Co Ltd, Yogin Si 17133, Gyeonggi Do, South Korea; Elect & Telecommun Res Inst, Emerging Nanomat Res Sect, Daejeon 34129, South Korea; Kyung Hee Univ, Dept Adv Mat Engn Informat & Elect, Yongin 17104, Gyeonggi Do, South Korea; Univ Sci & Technol, Dept Adv Device Engn, Daejeon 34113, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | Yoon, Minjoong/B-1162-2008; Kim, Min Jung/IZE-1923-2023 | 57455214500; 58237328500; 57455677000; 58236848100; 57194613724; 57204538127; 7404035863; 7401616067; 53985749100; 55671230600 | jiyong.woo@knu.ac.kr;orion627@korea.ac.kr; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 122 | 16 | SCIE | PHYSICS, APPLIED | 2023 | 3.5 | 32.7 | 1.12 | 2025-06-25 | 5 | 6 | FILMS | Ferroelectric materials; Ferroelectricity; Hafnium oxides; Oxygen vacancies; Polarization; Power spectral density; Zirconium compounds; Condition; Electrical methods; Ferroelectric capacitors; Ferroelectric property; Key elements; Low-Frequency Noise; Noise analyse; Polarization properties; Switching characteristics; X-defects; X ray photoelectron spectroscopy | English | 2023 | 2023-04-17 | 10.1063/5.0140714 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Multifarious microbial biostimulants promote growth in Arachis hypogaea L. | Plant Growth Promoting Rhizobacteria (PGPR), a microbial biostimulant has been widely studied to stimulate plant growth through induction of natural biological processes. However, lack of successful validation under open field remains a barrier to mark their standard in agriculture. Therefore, the aim of the research was to highlight the potential of PGPR biostimulants via in vitro studies and subsequently to demonstrate the in planta evaluation in oilseed crop, Arachis hypogaea L. (Groundnut) under pot and field trials. The two rhizobacterial strain was identified as Pseudomonas fluorescens and Bacillus subtilis by 16s rRNA gene sequence analysis. Both the strains were functionally screened for plant growth promoting traits. Pot and field trials were conducted where seeds were inoculated with PGPR biostimulants and harvested at 30 and 90 days. Biostimulant treatments were applied as single and co-inoculation in groundnut and the growth factors, biochemical parameters, yield, and seed quality were analyzed. The study inferred that the consortium of PGPR biostimulants significantly (p < 0.05) showed highest growth, photosynthetic pigments, nodulation status, leghaemoglobin content, yield attributes, and also biofortification of seed nutrients in oilseed crop under both pot and field conditions than un-inoculated control. This study supports the idea of the application of PGPR as microbial biostimulants through successful open field trial to facilitate its implementation as a feasible and potential agricultural product to synthetic fertilizers thereby influencing sustainable and stable crop production. | Eswaran, Sakthi Uma Devi; Sundaram, Lalitha; Siang, Tan Ching; Alharbi, Sulaiman Ali; Alahmadi, Tahani Awad; Kadam, Suhas Kishor | Periyar Univ, Sch Life Sci, Dept Bot, Soil Biol & PGPR Lab, Salem, India; KPJ Healthcare Univ Coll, Sch Pharm, Nilai, Malaysia; King Saud Univ, Coll Sci, Dept Bot & Microbiol, Riyadh, Saudi Arabia; King Saud Univ, Coll Med, Dept Pediat, Riyadh, Saudi Arabia; King Saud Univ, King Khalid Univ Hosp, Riyadh, Saudi Arabia; Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Sch Life Sci, Dept Biol, Daegu, South Korea | Kadam, Dr Suhas/HNI-6437-2023; Kadam, Dr. Suhas/HNI-6437-2023; alharbi, sulaiman/KHE-3282-2024; Eswaran, Sakthi/KIJ-8762-2024 | 58284282800; 54685155000; 56893025800; 59157644200; 57195590823; 57188723669 | lara9k@gmail.com;tcsiang@kpjuc.edu.my; | FRONTIERS IN SUSTAINABLE FOOD SYSTEMS | FRONT SUSTAIN FOOD S | 2571-581X | 7 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 3.7 | 32.7 | 1.11 | 2025-06-25 | 5 | 7 | Arachis hypogaea; Bacillus subtilis; biostimulants; groundnut; Pseudomonas fluorescens | WHEAT GROWTH; RHIZOBACTERIA; BACTERIA; NITROGEN; ASSAY; IRON | Arachis hypogaea; Bacillus subtilis; biostimulants; groundnut; Pseudomonas fluorescens | English | 2023 | 2023-05-02 | 10.3389/fsufs.2023.1170374 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Phase-field analysis of the effects of particle size, diffusivities, and mechanical properties on the cracking of silicon nanoparticle | In this study, a multiphysics model that reproduces the cracking of Si nanoparticle for a battery application was demonstrated. Two types of cracks appear on Si nanoparticle during lithiation. An essential condition for surface crack (SC) nucleation and propagation is a fast charging rate to form a high concentration gradient of lithium ions near the surface. A slower charging rate induces internal cracks (ICs) radiating from the center of the particle. The critical charging rates, at which SC or IC occurs, decrease rapidly with increasing particle radius. This indicates the difficulty of cracking of small nanoparticles, which is in a good agreement with the previous experimental results. Multiple cracks can appear in the particle, especially when the diffusivity is high. These cracks can be combined during the charging process, leading to the fracture or isolation of the particles. Additionally, two different peak stresses and Young's moduli from the literature were used considering their effects on the cracking of Si nanoparticle films. We believe our results provide a guideline for the fabrication and operation of Si nanoparticle-based anodes for lithium ion batteries. | Choi, Junhyeok; Lee, Yong Min; Kim, Sung Yeol | Kyungpook Natl Univ, Sch Mech Engn, Daegu 702701, South Korea; Daegu Gyeongbuk Inst Sci & Technol DGIST, Dept Energy Sci & Engn, Daegu 42988, South Korea; Daegu Gyeongbuk Inst Sci & Technol DGIST, Energy Sci & Engn Res Ctr, Daegu 42988, South Korea | ; Lee, YongMin/LTY-8230-2024; kim, sung/D-1412-2013; Kim, Sung Yeol/D-1412-2013 | 57221311984; 57819286000; 19337822900 | sykim.knu@gmail.com; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 123 | 20 | SCIE | PHYSICS, APPLIED | 2023 | 3.5 | 32.7 | 0 | 2025-06-25 | 0 | 0 | INDUCED FRACTURE; ANODE MATERIAL; LITHIUM; LITHIATION; ELECTRODE; BATTERIES; BEHAVIOR; MODEL | Charging (batteries); Elastic moduli; Integrated circuits; Lithium-ion batteries; Nanoparticles; Particle size; Particle size analysis; Silicon; Battery applications; Charging rate; Field analysis; Internal crack; Multiphysics model; Particles sizes; Phase fields; Si nanoparticles; Silicon nanoparticles; Surface cracks; Cracks | English | 2023 | 2023-11-13 | 10.1063/5.0179804 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Super-steep synapses based on positive feedback devices for reliable binary neural networks | This work proposes positive feedback (PF) device-based synaptic devices for reliable binary neural networks (BNNs). Due to PF operation, the fabricated PF device shows a high on/off current ratio (2.69 x 10(7)). The PF device has a charge-trap layer by which the turn-on voltage (V-on) of the device can be adjusted by program/erase operations and a long-term memory function is implemented. Also, due to the steep switching characteristics of the PF device, the conductance becomes tolerant to the retention time and the variation in turn-on voltage. Simulations show that high accuracy (88.44% for CIFAR-10 image classification) can be achieved in hardware-based BNNs using PF devices with these properties as synapses. | Kwon, Dongseok; Kim, Hyeongsu; Lee, Kyu-Ho; Hwang, Joon; Shin, Wonjun; Bae, Jong-Ho; Woo, Sung Yun; Lee, Jong-Ho | Seoul Natl Univ, Interuniv Semicond Res Ctr, Dept Elect & Comp Engn, Seoul 08826, South Korea; Kookmin Univ, Sch Elect Engn, Seoul 02707, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea; Minist Sci & ICT, Sejong, South Korea | ; Kwon, Dongseok/JDC-8584-2023; Lee, Jingyu/AAV-8920-2020; Bae, Jong-Ho/V-5237-2019 | 57203288190; 57204692859; 57919620700; 57224668810; 57210823123; 55339347700; 57201527826; 57221622173 | sywoo@knu.ac.kr;jhl@snu.ac.kr; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 122 | 10 | SCIE | PHYSICS, APPLIED | 2023 | 3.5 | 32.7 | 0.37 | 2025-06-25 | 2 | 2 | FLASH MEMORY; NONVOLATILE | Binary neural networks; Charge trap; Erase operation; Feedback device; Feedback operations; ON/OFF current ratio; On/off-current ratios; Program/erase; Trap layers; Turn-on voltages; Physical properties | English | 2023 | 2023-03-06 | 10.1063/5.0131235 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The performance of major airports in the Europe, North America and Asia | Purpose This study aims to provide a meaningful comparison of airports' performance and better understand the differences observed in the analysed airport performance by presenting a model to analyse the relationship between operational and financial performance and airport characteristics.Design/methodology/approach This study uses a quantitative analysis approach. The Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and entropy weight were utilised to analyse 17 airports in three Airports Council International regions: Asia, Europe and North America. Through operational and financial factors, these sample airports identified the most efficiently operated airports from 2016 to 2019.Findings Overall, Asian airports were superior in operational and financial efficiency. Unlike operating performance, the sample airport's financial and total performance results show a similar trend. There were no noticeable changes in operational factors. Therefore, differences in financial variables for each airport may affect the total performance.Practical implications This study provides insightful implications for airport policymakers to establish a standardised information disclosure foundation for consistent analysis and encourage airports to provide this information.Originality/value The adoption of Earnings Before Interest, Taxes, Depreciation, and Amortisation (EBITDA) to debt ratio and EBITDA per passenger, which had previously been underutilised in the previous study as financial factors, demonstrated differences between airports for airport stakeholders. In addition, the study presented a model that facilitates producing more intuitive results using TOPSIS, which was relatively underutilised compared to other methodologies such as date envelopment analysis. | Park, Jae-Woo; Roh, Saeyeon; Jang, Hyunmi; Seo, Young-Joon | Univ Plymouth, Plymouth Business Sch, Plymouth, England; Pusan Natl Univ, Grad Sch Int Studies, Busan, South Korea; Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea | Seo, Young-Joon/AAY-6105-2021; Roh, Saeyeon/MTG-0326-2025 | 58260398400; 56548238400; 57674212200; 56999695700 | pridejw@gmail.com;saeyeon.roh@plymouth.ac.uk;jangh01@pusan.ac.kr;y.seo@knu.ac.kr; | ASIA PACIFIC JOURNAL OF MARKETING AND LOGISTICS | ASIA PAC J MARKET LO | 1355-5855 | 1758-4248 | 35 | 11 | SSCI | BUSINESS | 2023 | 3.9 | 32.7 | 0.1 | 2025-06-25 | 0 | 1 | Airport management; Airport efficiency performance; TOPSIS; Operational and financial performance | BUSINESS PERFORMANCE; EMPIRICAL-EVIDENCE; EFFICIENCY; BENCHMARKING | Airport efficiency performance; Airport management; Operational and financial performance; TOPSIS | English | 2023 | 2023-11-22 | 10.1108/apjml-07-2022-0608 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Understanding ovonic threshold switching of GeSe chalcogenide materials using electrical methodologies for extracting density of states | As trap-related conduction is crucial in achieving ovonic threshold switching characteristics, identifying the distribution of traps in the chalcogenide matrix is essential. Herein, the density of states (DOS) near the valence band maximum level (E-V) and conduction band minimum level (E-C) of GeSe layers extracted using various electrical methodologies were analyzed. When electrons in the GeSe layer participate in activation under light injection, the DOS distribution at E-V can be calculated. On the other hand, capacitance measurement with respect to frequencies allows the identification of the lowest energy levels of E-C containing electrons that can respond to the provided AC signals. When an As dopant is introduced into the GeSe layer, the unified DOS distribution indicates a decrease in the Se element concentration owing to the over-coordinated Ge state. Therefore, increased DOS at E-C is observed, which is in good agreement with the ab initio explanation. Additional simulations were performed considering plausible scenarios in which the variation in DOS profile depends on the parameters of the transport mechanism. These results reveal the ways in which threshold switching can be controlled and facilitate the understanding of electrically achieved behavior. | Kim, Donguk; Yang, Tae Jun; Choi, Woo Sik; Lee, Hee Jun; Jang, Jun Tae; Hong, Eunryeong; Yang, Woo Young; Choi, Minwoo; Yang, Ki Yeon; Lee, Chang Seung; Woo, Jiyong; Kim, Dae Hwan | Kookmin Univ, Sch Elect Engn, Seoul 02707, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Samsung Adv Inst Technol, Thin Film Tech Unit, Suwon 16678, South Korea | Lee, Heejun/AAN-9070-2021; KIM, HYUNGTAK/P-7054-2015 | 57212681896; 57428906500; 57219537079; 57836279300; 56489218700; 57556070800; 55501121100; 57193221460; 15077646200; 35324868300; 53985749100; 57198637496 | jiyong.woo@knu.ac.kr;drlift@kookmin.ac.kr; | APPLIED PHYSICS LETTERS | APPL PHYS LETT | 0003-6951 | 1077-3118 | 123 | 7 | SCIE | PHYSICS, APPLIED | 2023 | 3.5 | 32.7 | 0.19 | 2025-06-25 | 1 | 1 | Chalcogenides; Germanium compounds; Selenium compounds; Chalcogenide materials; Conduction-band minimum; Densities of state; Density of states distribution; Light injection; matrix; Maximum levels; Switching characteristics; Threshold switching; Valence-band maximums; Capacitance measurement | English | 2023 | 2023-08-14 | 10.1063/5.0153403 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Construction of pseudo-Hessian for vertical seismic profile full waveform inversion | The pseudo-Hessian matrix has been widely developed and applied to full waveform inversion to reduce the computational cost of obtaining the Hessian and its inverse matrix. Because the conventional pseudo-Hessian matrix assumes a surface seismic profiling geometry, this conventional method is compatible only with hori-zontally deployed sources and receiver geometries and cannot reflect the geometrical spreading effect of verti-cally deployed receivers. To enable the pseudo-Hessian to properly consider vertically deployed receiver locations and the geometrical spreading inherent in vertical seismic profiling data, we re-formulate part of the pseudo-Hessian matrix formulation. We verify our new scheme by directly calculating the Hessian matrices for a simple 1D model and conducting inversion tests with synthetic data sets. A comparison to the approximated Hessian matrix confirms that the vertical seismic profiling pseudo-Hessian provides better agreement with the approximated Hessian than the conventional pseudo-Hessian. In addition, we describe two numerical tests using multi-offset synthetic vertical seismic profiling data sets. When we apply the conventional pseudo-Hessian matrix to invert the synthetic data, we find that the inversion process cannot properly invert far offset data. However, we find that the pseudo-Hessian regarding vertical seismic profiling geometry allows the inversion process to invert far offset data and produces fewer artifacts than the conventional method. This study demonstrates that the vertical seismic profiling pseudo-Hessian matrix represents an alternative method that is necessary for the calculation of the pseudo-Hessian matrix for full waveform inversion with vertical seismic profiling using the Gauss-Newton method. | Jun, Hyunggu; Yoon, Byoungjoon; Cho, Yongchae | Kyungpook Natl Univ, Dept Geol, 80 Daehak Ro, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, 124 Gwahak Ro, Daejeon 34132, South Korea; Seoul Natl Univ, Dept Energy Syst Engn, Seoul 08826, South Korea | Cho, Yongchae/AAA-7647-2021; Jun, Hyunggu/ABT-7172-2022 | 56048061400; 55032718100; 55513719100 | yc.cho@snu.ac.kr; | JOURNAL OF APPLIED GEOPHYSICS | J APPL GEOPHYS | 0926-9851 | 1879-1859 | 216 | SCIE | GEOSCIENCES, MULTIDISCIPLINARY;MINING & MINERAL PROCESSING | 2023 | 2.2 | 32.8 | 0 | 2025-06-25 | 0 | 0 | Hessian; Vertical-seismic profile (VSP); Full-waveform inversion (FWI); Acoustic wave | NEWTON; MIGRATION; VSP | Acoustic wave; Full-waveform inversion (FWI); Hessian; Vertical-seismic profile (VSP) | Inverse problems; Newton-Raphson method; Seismic prospecting; Seismic waves; Seismology; Waveform analysis; Acoustics waves; Conventional methods; Full-waveform inversion; Geometrical spreading; Hessian; Hessian matrices; Vertical seismic profiles; Vertical seismic profiling; Vertical-seismic profile; acoustic wave; comparative study; geometry; inverse analysis; seismic data; seismic property; waveform analysis; Geometry | English | 2023 | 2023-09 | 10.1016/j.jappgeo.2023.105146 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | In Vitro and In Vivo Coinfection and Superinfection Dynamics of Mayaro and Zika Viruses in Mosquito and Vertebrate Backgrounds | Epidemiological and clinical studies indicate that multiple arboviruses are cocirculating in human populations, leading to some individuals carrying more than one arbovirus at the same time. In turn, mosquitoes can become infected with multiple pathogens simultaneously (coinfection) or sequentially (superinfection). Globalization and climate change have contributed to the simultaneous increase and spread of arboviral diseases. Cocirculation of several arboviruses in the same geographic region provides an impetus to study the impacts of multiple concurrent infections within an individual vector mosquito. Here, we describe coinfection and superinfection with the Mayaro virus (Togaviridae, Alphavirus) and Zika virus (Flaviviridae, Flavivirus) in vertebrate and mosquito cells, as well as Aedes aegypti adult mosquitoes, to understand the interaction dynamics of these pathogens and effects on viral infection, dissemination, and transmission. Aedes aegypti mosquitoes were able to be infected with and transmit both pathogens simultaneously. However, whereas Mayaro virus was largely unaffected by coinfection, it had a negative impact on infection and dissemination rates for Zika virus compared to single infection scenarios. Superinfection of Mayaro virus atop a previous Zika virus infection resulted in increased Mayaro virus infection rates. At the cellular level, we found that mosquito and vertebrate cells were also capable of being simultaneously infected with both pathogens. Similar to our findings in vivo, Mayaro virus negatively affected Zika virus replication in vertebrate cells, displaying complete blocking under certain conditions. Viral interference did not occur in mosquito cells.IMPORTANCE Epidemiological and clinical studies indicate that multiple arboviruses are cocirculating in human populations, leading to some individuals carrying more than one arbovirus at the same time. In turn, mosquitoes can become infected with multiple pathogens simultaneously (coinfection) or sequentially (superinfection). Coinfection and superinfection can have synergistic, neutral, or antagonistic effects on viral infection dynamics and ultimately have impacts on human health. Here we investigate the interaction between Zika virus and Mayaro virus, two emerging mosquito-borne pathogens currently circulating together in Latin America and the Caribbean. We find a major mosquito vector of these viruses-Aedes aegypti-can carry and transmit both arboviruses at the same time. Our findings emphasize the importance of considering co- and superinfection dynamics during vector-pathogen interaction studies, surveillance programs, and risk assessment efforts in epidemic areas. | Brustolin, Marco; Pujhari, Sujit; Terradas, Gerard; Werling, Kristine; Asad, Sultan; Metz, Hillery C.

| ○ | ○ | Article | Multichamber PLGA Microparticles with Enhanced Monodispersity and Encapsulation Efficiency Fabricated by a Batch-Microfluidic Hybrid Approach | Microparticles with multiple internal chambers hold great promise as drug delivery systems due to their ability to sustain the release of drugs with short half-lives. However, conventional batch methods used for their fabrication have limitations in terms of encapsulation efficiency and particle size distributions, while microfluidic methods suffer from low production efficiency. Herein, a batch-microfluidic hybrid method is presented for fabricating poly(DL-lactic-co-glycolic acid) (PLGA) polymeric microparticles with uniformly distributed, multiple inner microchambers. A scalable batch method is utilized for primary water-in-oil (W/O) emulsions, combined with a precise microfluidic approach for generating controlled secondary emulsions. This approach results in highly uniform PLGA microparticles with tunable size and improved encapsulation efficiency. Additionally, the effect of polydopamine-based surface hydrophilic modification of microfluidic channels on drug encapsulation efficiency is investigated, achieving an efficiency of approximately 85%. The prepared multichamber PLGA microparticles exhibit an extended-release profile without initial burst release, demonstrating their potential for sustained drug delivery in various biomedical applications. A batch-microfluidic hybrid approach that can fabricate multichamber PLGA microparticles is presented. The multichambered PLGA microparticles prepared by the hybrid method exhibit high monodispersity, improved encapsulation efficiency, size controllability, and sustained drug release profiles without initial burst release.image & COPY; 2023 WILEY-VCH GmbH | Choi, Sunghak; Kang, Bong Su; Choi, Geonjun; Kang, Minsu; Park, Haena; Kim, Nahyun; Chang, Pahn-Shick; Kwak, Moon Kyu; Jeong, Hoon Eui; Jung, Ho-Sup | Seoul Natl Univ, Dept Food Sci & Biotechnol, Seoul 08826, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Dept Mech Engn, Ulsan 44919, South Korea; Seoul Natl Univ, Dept Agr Biotechnol, Seoul 08826, South Korea; Nbiocelle Inc, Shihung 15011, South Korea; Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea | ; Kwak, Moon/AGQ-6058-2022; Jung, Hosup/AAB-5708-2020 | 57264013200; 55330925300; 57222136967; 57190973131; 57225150256; 58561768300; 35749476600; 57203947984; 35490647000; 36985354800 | hoonejeong@unist.ac.kr;jhs@snu.ac.kr; | ADVANCED NANOBIOMED RESEARCH | ADV NANOBIOMED RES | 2699-9307 | 3 | 10 | ESCI | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 4 | 32.9 | 0.68 | 2025-06-25 | 3 | 4 | drug delivery; emulsion; microchannel; poly(lactic-co-glycolic acid) microsphere; porous microparticles | FLOW-FOCUSING DEVICE; CONTROLLED-RELEASE; SUSTAINED-RELEASE; DROPLET SIZE; DRUG-RELEASE; DELIVERY; EMULSIONS; POLYDISPERSITY; MICROSPHERES; NANOPARTICLES | drug delivery; emulsion; microchannel; poly(lactic-co-glycolic acid) microsphere; porous microparticles | English | 2023 | 2023-10 | 10.1002/anbr.202300044 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Network SLO-aware container scheduling in Kubernetes | In clouds, various services run on respective containers and have service-level objectives (SLO) that significantly impact service qualities. However, Kubernetes, a widely used container orchestration platform, does not schedule containers with respect to the network SLOs. This paper proposes a new container scheduling tech-nique consisting of a cloud-level and node-level scheduler. The cloud-level sched-uler selects a node that is best suited for satisfying the network SLO, and the node-level scheduler adjusts the CPU allocation for the container to satisfy SLOs on the selected node. We implement the cloud-level scheduler in Kubernetes and the node-level scheduler in the Linux kernel module and evaluate them using simulation and actual deployment. The evaluation results show that the cloud-level scheduler reduces the scheduling overhead by 22x compared to DRF, a representative multi-resource scheduling technique. Also, the node-level scheduler increases the number of containers that satisfy SLOs by 2.5x compared to native Kubernetes, which will significantly enhance the service quality of user-facing services. | Kim, Eunsook; Lee, Kyungwoon; Yoo, Chuck | Kakao Enterprise, Pangyoyeok Ro 235, Seongnam 13494, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Univ, Coll Informat, 145 Anam Ro, Seoul 02841, South Korea | Lee, Kyungwoon/AGE-8826-2022 | 57221946408; 57190025432; 7201746401 | eden.do@kakaoenterprise.com;kwlee87@knu.ac.kr;chuckyoo@os.korea.ac.kr; | JOURNAL OF SUPERCOMPUTING | J SUPERCOMPUT | 0920-8542 | 1573-0484 | 79 | 10 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, THEORY & METHODS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2023 | 2.5 | 33.0 | 0.36 | 2025-06-25 | 3 | 3 | Container scheduling; Service-level objectives; Service quality; Network performance | Container scheduling; Network performance; Service quality; Service-level objectives | Computer operating systems; Quality of service; Container scheduling; Evaluation results; Kernel modules; Linux kernel; Multi-resource; Networks services; Resource-scheduling; Scheduling techniques; Service level objective; Service Quality; Containers | English | 2023 | 2023-07 | 10.1007/s11227-023-05122-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Inter- rater agreement between radiologists using the novel CT- TDV (T3c+; tumour deposits; EMVI) system in patients with potentially curable right colon cancer | Objectives: The novel CT- TDV scoring system, identi-fying T3c + disease; the presence/absence of tumour deposits and EMVI has been shown to be superior in predicting prognosis when compared to the CT- TNM staging system in the evaluation of colon cancer. Repro-ducibility of this scoring system between specialist GI radiologists has not been assessed previously. The aim of this study was to assess the inter- rater agreement of gastrointestinal radiologists in assessing the novel pre-operative CT- TDV scoring of patients with potentially curable right- sided colon cancer.Methods: Ninety- three right colon cancer pre-operative CT scans were graded as CT TDV "good" versus TDV "poor" by four radiologists. Inter- rater agreement was assessed using the intraclass correlation coefficient (ICC) between all four readers and individual readers against the central radiologist using Cohen's kappa statistic.Results: The ICC comparing those graded as TDV "good" versus TDV "poor" for all 93 cases was 0.61 (0.51-0.70) indicating moderate reliability. Individual kappa scores across the 93 cases were 0.76, 0.59 and 0.59 (p < 0.001) indi-cating moderate to substantial agreement. Conclusion: The CT TDV scoring system is reproduc-ible amongst trained gastrointestinal radiologists in the assessment of newly diagnosed right colon cancer.Advances in knowledge: This further validates the clin-ical utility of the CT TDV scoring system as a prognostic tool to guide the management of patients with poten-tially curable right colon cancer. | Hodges, Nicola; Duxbury, Oliver; Corr, Alison; Cho, Seung Hyon; Miskovic, Danilo; Brown, Gina | St Marks Hosp, London, England; Imperial Coll London, Hammersmith Campus, London, England; Basingstoke & North Hampshire Hosp, Basingstoke, England; Kyungpook Natl Univ, Daehak Ro, Daegu, South Korea | BROWN, GINA/KYP-9274-2024 | 57314663300; 56453438000; 57210988905; 58264935900; 23980952800; 57198634877 | nicola.hodges@nhs.net; | BRITISH JOURNAL OF RADIOLOGY | BRIT J RADIOL | 0007-1285 | 1748-880X | 96 | 1146 | SCIE | RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2023 | 2.7 | 33.1 | 1.08 | 2025-06-25 | 4 | 5 | COMPUTED-TOMOGRAPHY; ACCURACY; FEATURES | Colonic Neoplasms; Extranodal Extension; Humans; Observer Variation; Radiologists; Reproducibility of Results; Tomography, X-Ray Computed; Article; cancer grading; cancer staging; colon cancer; comparative study; computer assisted tomography; correlation coefficient; CT-TDV scoring system; depth of invasion; extramural venous invasion; histology; human; interrater reliability; major clinical study; multidetector computed tomography; pathology; preoperative evaluation; radiologist; right colon cancer; scoring system; tumor invasion; colon tumor; diagnostic imaging; extranodal extension; observer variation; radiologist; reproducibility; x-ray computed tomography | English | 2023 | 2023-06-01 | 10.1259/bjr.20220682 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Knowledge, attitudes, and behaviors toward fertility preservation in patients with breast cancer: A cross-sectional survey of physicians | BackgroundFertility is an important issue for young women with breast cancer, but studies about physicians' knowledge, attitudes, and practices toward fertility preservation (FP) are largely based on Western populations and do not reflect recent international guidelines for FP. In this international study, we aimed to assess the knowledge, attitudes, and practices of physicians from South Korea, other Asian countries, and Latin America toward FP in young women with breast cancer, and identify the related barriers. MethodsThe survey was conducted anonymously among physicians from South Korea, other Asian countries, and Latin America involved in breast cancer care between November 2020 and July 2021. Topics included knowledge, attitudes, and perceptions toward FP; practice behaviors; barriers; and participant demographics. We grouped related questions around two main themes-discussion with patients about FP, and consultation and referral to a reproductive endocrinologist. We analyzed the relationships between main questions and other survey items. ResultsA total of 151 physicians completed the survey. Most participants' overall knowledge about FP was good. More than half of the participants answered that they discussed FP with their patients in most cases, but that personnel to facilitate discussions about FP and the provision of educational materials were limited. A major barrier was time constraints in the clinic (52.6%). Discussion, consultations, and referrals were more likely to be performed by surgeons who primarily treated patients with operable breast cancer (FP discussion odds ratio [OR]: 2.90; 95% confidence interval [CI]: 1.24-6.79; FP consultation and referral OR: 2.98; 95% CI: 1.14-7.74). Participants' knowledge and attitudes about FP were significantly associated with discussion, consultations, and referrals. ConclusionPhysicians from South Korea, other Asian countries, and Latin America are knowledgeable about FP and most perform practice behaviors toward FP well. Physicians' knowledge and favorable attitudes are significantly related to discussion with patients, as well as consultation with and referral to reproductive endocrinologists. However, there are also barriers, such as limitations to human resources and materials, suggesting a need for a systematic approach to improve FP for young women with breast cancer. | Baek, Soo Yeon; Lee, Kyung-Hun; Kim, Sung-Bae; Gomez, Henry; Vidaurre, Tatiana; Park, Yeon Hee; Ahn, Hee Kyung; Kim, Yoo Seok; Park, In Hae; Ahn, Sung Gwe; Lee, Jeeyeon; Jeong, Jae Ho; Kim, Seonok; Kim, Hee Jeong | Ajou Univ, Dept Surg, Sch Med, Suwon, South Korea; Seoul Natl Univ Hosp, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Canc Res Inst, Seoul, South Korea; Univ Ulsan, Asan Med Ctr, Dept Oncol, Coll Med, Seoul, South Korea; Inst Nacl Enfermedades Neoplas, Dept Med Oncol, Lima, Peru; Sungkyunkwan Univ, Samsung Med Ctr, Dept Med, Div Hematol Oncol,Sch Med, Seoul, South Korea; Gachon Univ, Dept Internal Med, Div Med Oncol, Gil Med Ctr, Incheon, South Korea; Chosun Univ, Chosun Univ Hosp, Dept Surg, Coll Med, Gwangju, South Korea; Korea Univ, Guro Hosp, Dept Internal Med, Div Hematol Oncol,Coll Med, Seoul, South Korea; Yonsei Univ, Gangnam Severance Hosp, Dept Surg, Coll Med, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Surg, Daegu, South Korea; Asan Med Ctr, Dept Clin Epidemiol & Biostat, Seoul, South Korea; Univ Ulsan, Asan Med Ctr, Dept Surg, Div Breast Surg,Coll Med, Seoul, South Korea | ; Gomez, Henry/AGN-8948-2022; Kim, Sung/AAI-3081-2021; Ahn, Sung Gwe/AFD-8122-2022; KIM, SEON-OK/HGC-7012-2022 | 57211318429; 55549466700; 34770722200; 59185183900; 14631254100; 35273175600; 50261094700; 55905081700; 25636160300; 36336893800; 37079213100; 57022763500; 57196230629; 14626479600 | heejeong_kim@amc.seoul.kr; | FRONTIERS IN ONCOLOGY | FRONT ONCOL | 2234-943X | 13 | SCIE | ONCOLOGY | 2023 | 3.5 | 33.1 | 0.3 | 2025-06-25 | 2 | 2 | breast cancer; young age; fertility preservation; consultation and referral; survivorship | DECISION AID; YOUNG-WOMEN; SURVIVORS; ISSUES; AGE | breast cancer; consultation and referral; fertility preservation; survivorship; young age | Article; breast cancer; consultation; cross-sectional study; female; fertility preservation; health education; human; Likert scale; male; patient referral; perception; physician attitude; questionnaire; time; time constraint | English | 2023 | 2023-01-23 | 10.3389/fonc.2023.1109694 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
