| ○ | Conference paper | Birefringence Behaviors of Cellulose Nanocrystals under Varied Concentrations, Ultrasonication Treatments, and Different Solvents | Self-assembly of cellulose nanocrystal (NCC) in suspension has unique characteristics under polarize observation which is called as birefringence behaviors. However, the study about these phenomena is lacking especially when the NCC is prepared in dried powder form. Here, we reported the behaviors of commercial NCC obtained from CelluForce NCC, NCV100-NASD90 dispersed in different concentrations (0.1% to 8% weight/weight); ultrasonic times (0 to 45 minutes); solvents (Benzene, N,N-Dimethylacetamide (DMA), Ethanol, Dimethylformamide, Acetone, Acetic acid 1%, and Water) for their birefringence manners. In addition, nanocellulose obtained from TEMPO mediated oxidation and organic acid hydrolysis were also reported. Dried powder NCC showed shear thickening behavior at high concentration and well-dispersed at acetic acid and water solvent indicated the redispersable NCC. While, cellulose NCC, NCV100-NASD90 considerably low dispersion in non-polar solvents. Birefringence appears only when the suspension was in anisotropic state due to stirring. As sonication times increased, the birefringence clearly visible which suggested the defibrillation of aggregated cellulose crystal. The results of this study authenticated that redispersable NCC could be obtained from dried powder cellulose and provided birefringence behavior by managing concentration levels, sonication times and perfect solvents to dilute. © Published under licence by IOP Publishing Ltd. | Masruchin, N.; Zendrato, H.M.; Jayalaksmana, M.; Nugroho, R.W.N.; Holilah; Nuryawan, A.; Mardawati, E.; Lawi, A.; Park, B.D.; Azizan, A. | Research Center for Biomass and Bioproducts, National Research and Innovation Agency (BRIN), KST Soekarno, Cibinong, 16911, Indonesia, Research Center for Nanocellulose between BRIN and Universitas Andalas, Padang, 25163, Indonesia, Research Center for Biomass and Biorefinery between BRIN and Universitas Padjadjaran, Jatinangor, 45363, Indonesia; Research Center for Biomass and Bioproducts, National Research and Innovation Agency (BRIN), KST Soekarno, Cibinong, 16911, Indonesia, Department of Forest Products, Faculty of Forestry and Environment, Bogor Agricultural University, Bogor, 16680, Indonesia; Research Center for Biomass and Bioproducts, National Research and Innovation Agency (BRIN), KST Soekarno, Cibinong, 16911, Indonesia; Research Center for Biomass and Bioproducts, National Research and Innovation Agency (BRIN), KST Soekarno, Cibinong, 16911, Indonesia, Research Center for Biomass and Biorefinery between BRIN and Universitas Padjadjaran, Jatinangor, 45363, Indonesia; Research Center for Biomass and Bioproducts, National Research and Innovation Agency (BRIN), KST Soekarno, Cibinong, 16911, Indonesia, Research Center for Biomass and Biorefinery between BRIN and Universitas Padjadjaran, Jatinangor, 45363, Indonesia; Faculty of Forestry, Universitas Sumatera Utara, 2nd Campus, Deli Serdang Regency, North Sumatra, Indonesia; Research Center for Biomass and Biorefinery between BRIN and Universitas Padjadjaran, Jatinangor, 45363, Indonesia, Department of Agro-industrial Technology, Faculty of Agro-industrial Technology, Universitas Padjadjaran, Jatinangor, 45363, Indonesia; Department of Industrial Engineering, Institut Teknologi Batam, Batam, 29425, Indonesia; Department of Wood and Paper Science, Kyungpook National University, Daegu, 41566, South Korea; School of Chemical Engineering, College of Engineering, Universiti Teknologi MARA (UiTM), Selangor, Shah Alam, 40450, Malaysia | 56586227800; 57226632383; 58951233800; 55273705400; 57190253672; 55813547000; 56419884100; 25655171100; 7402834820; 55779121900 | nana021@brin.go.id; | IOP Conference Series: Earth and Environmental Science | 1755-1307 | 1309 | 1 | 0 | 2025-04-16 | 1 | Birefringence; Cellulose Nanocrystals; Concentration; Solvents; Ultrasonication | English | Final | 2024 | 10.1088/1755-1315/1309/1/012003 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Bit-Separable Radix-4 Booth Multiplier for Power-Efficient CNN Accelerator | As the demand for efficient computational hardware escalates, optimizing power-hungry multipliers becomes paramount. This is particularly crucial as high-performance AI applications shift towards low-power edge devices, necessitating reduced power consumption. This paper introduces a novel bit-separable radix-4 Booth multiplier tailored for low-power training and inference on edge device. Our proposed CNN accelerator with bit-separable multiplier maximizes hardware reusability through a structural division of the multiplicand and accelerates speed by first calculating the higher bits of the multiplicand and then decoding the dynamic range of results to omit processing of lower bits. To accommodate various AI models, experiments were conducted using expandable off-chip accelerators. We manufactured an off-chip accelerator chip using the commercial 130nm process. The experimental results showed that compared to the traditional radix-4 Booth multiplier, the chip size was reduced by 18.8%. There was a 68% decrease in total power consumption, a 47% increase in computational speed, and a 53% reduction in computational resources. | Park, Seunghyun; Park, Daejin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 57903951400; 55463943600 | boltanut@knu.ac.kr; | 2024 IEEE SYMPOSIUM IN LOW-POWER AND HIGH-SPEED CHIPS, COOL CHIPS 27 | 2473-4683 | 0 | 2025-04-16 | 0 | 0 | radix-4 Booth multiplier; low-power; bit-separable multiplier; edge device; dynamic range decoder | DESIGN | bit-separable multiplier; dynamic range decoder; edge device; low-power; radix-4 Booth multiplier | Decoding; Electric power utilization; Electron multipliers; Energy efficiency; Bit-separable multiplier; Booth multipliers; Dynamic range; Dynamic range decoder; Edge device; Low Power; Off-chip; Power efficient; Radix-4; Radix-4 booth multiplier; Reusability | English | 2024 | 2024 | 10.1109/coolchips61292.2024.10531170 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Broadband and strong visible-light driven photocatalytic enhancement utilizing two-dimensional plasmonics of Au/Cu-modified SrTiO3 perovskite nanostructures | Addressing limited access to clean drinking water demands innovative solutions to energy and environmental crises. Photocatalysis offers promise without eliciting secondary pollution, yet traditional metal oxide semiconductor photocatalysts encounter impediments in solar energy utilization and charge carrier recombination rates. To overcome these limitations, we present for the first time, a novel design, fabrication, and characterization of two-dimensional plasmonic noble metal/perovskite nanostructure hybrids for photocatalysis, combining Au as the plasmonic material with Cu-modified SrTiO3 as the semiconductor, fabricated on elastomeric polydimethylsiloxane substrates. Integrating localized surface plasmon resonance and Schottky junction-related band-bending significantly extends optical absorption into the ultraviolet-visible-infrared bands and enhances the effective carrier lifetimes, ensuring state-of-the-art photocatalytic efficiency. Exceptional photocatalytic performance in a 5-ppm aqueous methylene blue solution can be attained with 72.69-wt% Cu incorporation in the perovskite oxide, reaching a visible light-mediated photodegradation efficiency of 26% - an astounding 62.5-% efficiency increase compared to previous experiments without Cu modification. This advancement underscores the synergistic potential of noble metals and photocatalytic semiconductors in managing water purification challenges. © 2024 Elsevier GmbH | Sajjadian, S.T.; Chee, K.-W.-A.; Ejbarah, R.A.; Hamidi, S.M.; Alissa, Y.; Sadeghi, S. | Laser and Plasma Research Institute, Magneto-plasmonic Lab, Shahid Behesthi University, Tehran, 1983969411, Iran; National Education Center for Semiconductor Technology, Kyungpook National University, Daegu, 41566, South Korea, Institute of Semiconductor Fusion Technology, Kyungpook National University, Daegu, 415166, South Korea, School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 415166, South Korea, School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, 415166, South Korea; Petroleum and Gas Engineering Department, College of Engineering, University of Thi-Qar, Al-Nasiriyah, 64001, Iraq; Laser and Plasma Research Institute, Magneto-plasmonic Lab, Shahid Behesthi University, Tehran, 1983969411, Iran; Laser and Plasma Research Institute, Magneto-plasmonic Lab, Shahid Behesthi University, Tehran, 1983969411, Iran; Laser and Plasma Research Institute, Magneto-plasmonic Lab, Shahid Behesthi University, Tehran, 1983969411, Iran | 57743435700; 57524559900; 57219145992; 23469366100; 57743435600; 57212524429 | aghjuee@knu.ac.kr;m_hamidi@sbu.ac.ir; | Optik | 0030-4026 | 305 | 0.38 | 2025-05-07 | 1 | Charge carrier recombination; Localized surface plasmon resonance; Perovskite metal oxide; Plasmonic photocatalyst; Schottky barrier | Charge carriers; Copper compounds; Energy utilization; Light absorption; Oxide semiconductors; Perovskite; Photocatalysis; Plasmonics; Potable water; Precious metals; Schottky barrier diodes; Silver compounds; Solar energy; Strontium titanates; Substrates; Surface plasmon resonance; Water treatment; Charge carrier recombination; Localized surface plasmon resonance; Metal-oxide; Perovskite metal oxide; Photo-catalytic; Plasmonic photocatalysts; Plasmonics; Schottky barriers; Two-dimensional; Visible-light-driven; Nanostructures | English | Final | 2024 | 10.1016/j.ijleo.2024.171779 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | BTS: Bridging Text and Sound Modalities for Metadata-Aided Respiratory Sound Classification | Respiratory sound classification (RSC) is challenging due to varied acoustic signatures, primarily influenced by patient demographics and recording environments. To address this issue, we introduce a text-audio multimodal model that utilizes metadata of respiratory sounds, which provides useful complementary information for RSC. Specifically, we fine-tune a pretrained text-audio multimodal model using free-text descriptions derived from the sound samples' metadata which includes the gender and age of patients, type of recording devices, and recording location on the patient's body. Our method achieves state-of-the-art performance on the ICBHI dataset, surpassing the previous best result by a notable margin of 1.17%. This result validates the effectiveness of leveraging metadata and respiratory sound samples in enhancing RSC performance. Additionally, we investigate the model performance in the case where metadata is partially unavailable, which may occur in real-world clinical setting. | Kim, June-Woo; Toikkanen, Miika; Choi, Yera; Moon, Seoung-Eun; June, Ho-Young | Kyungpook Natl Univ, Dept AI, Daegu, South Korea; MODULABS, RSC LAB, Seoul, South Korea; NAVER Cloud, NAVER AI LAB, NAVER Digital Healthcare LAB, Seoul, South Korea | 57219550643; 57286454000; 59212879600; 59583667100; 57198760619 | kaen2891@knu.ac.kr;seongeun.moon@navercorp.com;hoyjung@knu.ac.kr; | INTERSPEECH 2024 | 2308-457X | 3.74 | 2025-05-07 | 1 | 2 | Respiratory Sound Classification; Pretrained Language-Audio Model; ICBHI; Metadata | ICBHI; Metadata; Pretrained Language-Audio Model; Respiratory Sound Classification | Arthroplasty; Audio recordings; Electronic health record; Population statistics; Sound recording; Acoustic signature; Audio modeling; ICBHI; Multimodal models; Pretrained language-audio model; Recording environment; Respiratory sound classification; Respiratory sounds; Sound classification; Sound sample; Metadata | English | 2024 | 2024 | 10.21437/interspeech.2024-492 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | Building Detection: Testing a New Object-Based Approach Against Neural Networks | Automated identification of HRBs (High-rise Buildings) on satellite images is challenging when densely populated areas are concerned. Factors that increase complexity are, among others, roads and both the azimuth and elevation angle of the sensor. In this study, two different effective HRB detection techniques are proposed. The first method is using CNNs (Convolutional Neural Networks), an extensively used tool for pattern recognition in the field of machine learning. However, domain movement considerably reduces the CNN's performance on the test data in other domains, making it difficult to generalize. Besides, obtaining the dense annotations on the remote sensing images is expensive and time-consuming. Therefore, a new object-based approach is proposed that includes multi-resolution segmentation and relief displacement by azimuth angles of the sensor. Both methods were tested using images from four regions in South Korea using VHR (Very High Resolution) satellite imagery from the KOMPSAT-3 and WorldView-3. The results show that the performance of both methods heavily depends on factors such as building size and density as well as on external factors such as the position, shape, and size of HRBs. It can be concluded that our proposed method using the relationship between the azimuth angle of the sensor and the relief displacement of the building has several distinct advantages over the CNN-based approach. E.g. the CNN performance considerably relies on the availability of a large number of training data. In addition, quantitative evaluation showed an accuracy improvement rate of at least 30% in intersection over union and F1 score compared to the object-based benchmark models. Eventually, our proposed method allows to evaluate the performance of each image individually, which helps to identify the scenarios where a certain method works best. © 2024 Korean Society of Surveying.

| ○ | Book chapter | Buoyant Convection of Nanofluid in an Annular Domain with Linear Heating | A numerical study has been performed to uncover the nonuniform heating on buoyant flow of nanofluid and associated thermal transport processes inside the annular geometry. The vertical boundaries of the annulus are differently heated with linear thermal profiles, and horizontal surfaces are kept insulated. Using vorticity-stream function formulation, the governing model equations are integrated using time-splitting and relaxation finite difference techniques. The simulation predictions are illustrated through streamline and isotherms and heat transport rates in terms of the average Nusselt numbers for a wider range of chosen parameters. In particular, the impacts of radius and aspect ratios on the buoyant convection and thermal transport rates have been investigated. The simulation predictions reveal that the flow and thermal distribution along with thermal transport rates are significantly modified by aspect and radius ratios. Heat transport rates are augmented with an enhancement in nanoparticle concentrations as well as radius ratio. The aspect ratio has a significant impact on flow and thermal transport rates in comparison with remaining parameters. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. | Kiran, S.; Sankar, M.; Girish, N.; Kumara Swamy, H.A. | Department of Mathematics, Nitte Meenakshi Institute of Technology, Karnataka, Bengaluru, India; Department of Information Technology, University of Technology and Applied Sciences, Ibri, Oman; Department of Mathematics, JSS Academy of Technical Education, Bengaluru, India; Department of Mathematics, Nonlinear Dynamics and Mathematical Application Center, Kyungpook National University, South Korea | 57190864069; 6701530391; 57205729755; 57223027638 | Trends in Mathematics | 2297-0215 | Part F2357 | 0 | 2025-05-07 | 0 | Annulus; Aspect ratio; Linear heating; Nanofluids; Radius ratio | English | Final | 2024 | 10.1007/978-3-031-41420-6_30 | 바로가기 | 바로가기 | ||||||||||||||||||

The newly generated impurity in the molecular chain produced the new energy states by the thermal aging process. The quantum chemical calculation contributed to analyzing these microscopic changes in energy state. In particular, the increases of deep traps greatly affected the space charge dynamics and breakdown strength.

| ○ | Article | Can FinTech transform corporate liquidity? Evidence from China | The rapid growth of China's financial technology has had a significant impact on businesses. The study of the relationship between macrofinancial technology and microbusinesses has important theoretical and practical implications. We empirically examined the relationship between FinTech, financing constraints, and corporate liquidity using the China Provincial Fintech Development Index and the data of A-share manufacturing companies listed on the Shanghai and Shenzhen Main Boards between 2011 and 2020. We found that financing constraints have a negative effect on a company's liquidity. The greater the constraints on corporate financing, the worse the liquidity. However, financial technology will have positive external effects and will mitigate the negative effect of financing constraints on corporate liquidity. In addition, we find that non-state-owned enterprises, small and medium-sized enterprises, and young enterprises face greater financing constraints and are thus more impacted by FinTech. © 2023 The Authors | Fan, Chenguang; Bae, Seongho; Liu, Yu | School of Business Administration, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, South Korea; School of Business Administration, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, South Korea; School of Business Administration, Kyungpook National University, 80, Daehak-ro, Buk-gu, Daegu, South Korea | 58702091300; 57190379529; 58701427800 | shobae@knu.ac.kr; | Innovation and Green Development | 2949-7531 | 3 | 2 | 7.01 | 2025-05-07 | 28 | Corporate liquidity; Financing constraints; FinTech | English | Final | 2024 | 10.1016/j.igd.2023.100114 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Book chapter | Carbon dioxide hydrogenation to methanol: New insights into the Cu-based bimetallic catalysts | CO2 hydrogenation to methanol has become an attractive field of study in recent years as it transforms the greenhouse gas (CO2) into valueadded chemicals. Copper-based catalysts have been used for this reaction due to their low cost and good selectivity for methanol over other metals. However, the CO2 conversion efficiency of Cu-based catalysts remains low even at very high reaction pressures. As a result, significant efforts have been directed towards tailoring the Cu-based catalysts to boost CO2 conversion without reducing methanol selectivity. One effective and practical strategy is to introduce a second metal, particularly Zn, to obtain bimetallic Cu-based catalysts. The addition of Zn to Cu results in a synergistic interaction between Cu and Zn, improving CO2 activation and methanol selectivity. The current chapter provides a detailed discussion on the fundamentals of CO2 chemistry, the evolution from mono-metallic to bimetallic catalysts for CO2 hydrogenation, operando studies, and the significance of bimetallic catalysts in CO2 chemisorption and methanol selectivity. In addition to that, special emphasis has been provided on the status of the reaction and prospects for material design to improve methanol selectivity. Finally, a future outlook for the development of Cu-based bimetallic catalysts is provided. © 2024 Nova Science Publishers, Inc. | Kasala, Prabhakar Reddy; Tonda, Surendar; Tulsani, Srikanth Reddy | Department of Chemistry and Biochemistry, University of South Carolina, Columbia, SC, United States; School of Architecture, Civil, Environmental and Energy Engineering, Kyungpook National University, Daegu, South Korea; Department of Physics, Malla Reddy College of Engineering and Technology, Hyderabad, Telangana, India | 59009252400; 56114866900; 57201276822 | mr.prabhakasala@gmail.com; | Bimetals: Formation, Properties and Applications | 0 | 2025-05-07 | 0 | English | Final | 2024 | 바로가기 | ||||||||||||||||||||||
| ○ | Conference paper | Carbon Dioxide Levels in Wheat Storage across Varied Environmental Conditions | Wheat (Triticum aestivum L.), a crucial global cereal, faces challenges in post-harvest storage due to decay and declining nutritional value, exacerbated by environmental fluctuations. With increasing demand for wheat-derived products and uncertain agricultural impacts of environmental shifts, these challenges become pressing. Heat generated by pests and microorganisms in stored grain leads to localized temperature increases, indicating compromised grain quality. Traditional monitoring methods involve temperature cables and destructive moisture content measurements. However, sensors must be placed close to temperature variations, limiting detection range and risking quality degradation and economic losses. Recent research highlights elevated carbon dioxide levels in stored grain as an additional quality indicator. Comparing carbon dioxide concentrations in grain to ambient air levels, typically below 400 ppm, can assess quality decline. Carbon dioxide diffusion in wheat grain exceeds that of heat, suggesting carbon dioxide sensing offers heightened sensitivity. This study focuses on using carbon dioxide sensors to monitor fluctuations in a specific Korean wheat cultivar within laboratory-scale storage conditions. Research covers various temperatures to understand carbon dioxide's role as an indicator of quality decline, aiding effective grain storage management. © 2024 ASABE Annual International Meeting.

| ○ | Article | Case study on urban water cycle improvement in Andong City using the SWMM-LID model | As global warming accelerates, the frequency and intensity of localized heavy rainfall events are increasing, leading to severe urban flooding and substantial inundation damage downstream. Urban areas with high impervious surfaces are particularly vulnerable, as rapid stormwater runoff during rainfall exacerbates flood risks. This study investigates the runoff reduction effects of Low Impact Development (LID) techniques applied through the Storm Water Management Model (SWMM) to mitigate urban runoff. Andong City Hall and Talchum Park in Andong City were selected as study sites to compare water balance changes before and after LID installation. The analysis revealed that after implementing LID techniques, evaporation increased by 9.8% to 12.5%, infiltration increased by 111.0% to 139.2%, and runoff decreased by 31.8% to 38.8%. These results indicate that LID techniques effectively enhance water evaporation and infiltration, improving the water cycle in highly impervious areas and mitigating urban flooding and inundation damage. © 2024 Korea Water Resources Association.

| ○ | Article | CHAPSAP26-161, A Truncated Protein and Enzymatic Active Domain of Endolysin LysSAP26, as a Potential Therapeutic Agent to Combat Clostridioides difficile Infection | Clostridioides difficile is a spore-forming enteric pathogen that causes life-threatening diarrhea and colitis. Notably, C. difficile infection (CDI) is a major healthcare-associated infection with increasing incidence and morbidity rates. Antibiotic-induced microbial disruption has been linked to susceptibility to CDI transmission and relapse. Therefore, alternative therapeutic approaches that effectively prevent C. difficile growth and spore germination are urgently needed. Bacteriophage-derived endolysins and their derivatives have recently shown potential as novel antibacterial agents. Hence, this study aimed to investigate the efficacy of a novel truncated cysteine-histidine-dependent amidohydrolase/peptidase (CHAP) modular endolysin, CHAPSAP26-161, in combating CDI. In vitro studies demonstrated its potent bactericidal activity against several clinically relevant C. difficile strains, including toxin A-and toxin B-producing and nontoxigenic strains. CHAPSAP26-161 exhibited rapid and specific killing activity, thereby significantly reducing C. difficile colony-forming units. Furthermore, in a murine CDI model, CHAPSAP26-161 treatment remarkably reduced C. difficile burden and clinical symptoms, such as diarrhea and weight loss. In histopathological analysis, colonic inflammation and tissue damage decreased in CHAPSAP26-161-treated mice compared with that in the control group. More-over, no cytotoxic effects were observed on the A549 cell line, indicating that CHAPSAP26-161 is safe as a therapeutic agent. These findings highlight that CHAPSAP26-161 is a promising treatment option for CDI. Importantly, preclinical and clinical studies are warranted to fully evaluate the therapeutic potential of CHAPSAP26-161 and its possible implementation in clinical practice. © 2024 Journal of Bacteriology and Virology. | Dahal, Ram Hari; Choi, Yoon-Jung; Kim, Shukho; Kim, Jungmin | Department of Microbiology, School of Medicine, Kyungpook National University, Daegu, 41944, South Korea; Department of Microbiology, School of Medicine, Kyungpook National University, Daegu, 41944, South Korea; Department of Microbiology, School of Medicine, Kyungpook National University, Daegu, 41944, South Korea; Department of Microbiology, School of Medicine, Kyungpook National University, Daegu, 41944, South Korea | 57110097800; 57220082311; 24341187900; 57211297681 | minkim@knu.ac.kr; | Journal of Bacteriology and Virology | 1598-2467 | 54 | 2 | 0 | 2025-05-07 | 0 | Alternatives antibiotics; Clostridioides difficile infection (CDI); Colonic inflammation; Endolysin | clindamycin; colistin; cysteine histidine dependent amidohydrolase peptidase sap26 161; endolysin; gentamicin; kanamycin; metronidazole; unclassified drug; vancomycin; virus enzyme; A-549 cell line; animal experiment; animal model; animal tissue; Article; bacterial load; bactericidal activity; bacteriophage; body weight loss; clinical feature; clinical outcome; clinical significance; Clostridioides difficile; Clostridium difficile infection; colitis; controlled study; diarrhea; drug cytotoxicity; drug efficacy; drug safety; dysbiosis; female; histopathology; human; human cell; in vitro study; minimum bactericidal concentration; minimum inhibitory concentration; mortality; mouse; murine model; nonhuman; protein purification; tissue injury | English | Final | 2024 | 10.4167/jbv.2024.54.2.107 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Characteristics of Basepaper from Bamboo Pulps for Air Filter Application; [대나무 펄프 기반의 공기 정화 필터용 원지 특성 평가] | As air pollution issues such as fine dust particles become increasingly severe, the consumption of air purification devices equipped with various types of filters has surged. Polypropylene (PP), commonly used as a filter material, is easy to process and exhibits excellent physical properties. However, its non-biodegradable nature makes recycling difficult, leading to secondary environmental pollution during landfills or incineration. To address this issue, this study fabricated high-basis-weight filter basepaper by mixing bamboo pulp produced via organosolv pulping with low melting point polyester (LMPET), polyethylene (PE)/polypropylene (PP) fibers, and activated carbon fibers using a wet-laid process on a pilot-scale paper machine. Analysis of the filter efficiency depending on the mixing ratio and basis weight revealed that the bamboo-based basepaper achieved up to 6% higher dust particle filtration efficiency for the 3.0–5.0 µm range and exhibited 40–50% lower differential pressure compared to PET Spunbond, commonly used as a filter substrate. Furthermore, the quality factor (QF), which comprehensively considers filtration efficiency and differential pressure, showed that bamboo-based basepaper achieved a value 2.3 times higher than PET Spunbond, demonstrating superior performance in air permeability and energy efficiency. These results indicate that environmentally friendly bamboo-based basepaper has the potential to reduce long-term operating costs and serve as an economical and sustainable carbon-neutral filter substrate, providing a viable alternative to conventional petroleum-based filter materials. © 2024 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | ○ | Article | Characteristics of methicillin-resistant Staphylococcus aureus isolates from bovine mastitis milk in South Korea: molecular characteristics, biofilm, virulence, and antimicrobial resistance | Methicillin-resistant Staphylococcus aureus (MRSA) is a drug-resistant pathogen causing subclinical and clinical bovine mastitis. This study examined the molecular properties, biofilm formation, virulence genes, and antimicrobial susceptibility of MRSA isolates from mastitis-infected dairy cow milk in South Korea. Whole-genome sequencing of an ST22-SCCmec IV MRSA strain positive for Panton-Valentine leukocidin (PVL) and toxic shock syndrome toxin-1 (TSST-1) was also performed. Of the 488 S. aureus isolates, 30 (6.1%) were identified as MRSA, harboring the mecA gene. MRSA exhibited the highest resistance to kanamycin (66.7%) among non-beta-lactam antibiotics. Multidrug resistance was observed in 83.3% of MRSA isolates. All MRSA strains had the capacity to form biofilm and harbored biofilm-related genes. The primary virulence genes included hla, hlb, lukED, seg, sei, sem, sen, and seo. The ST72-t324-SCCmec IV genotype was the most prevalent. Of note, three ST22-SCCmec IV isolates were positive for PVL and TSST-1. Our findings suggest that the majority of MRSA isolates from milk obtained from dairy cows with mastitis are multidrug-resistant, capable of forming robust biofilms, and harbor multiple virulence genes. The presence of PVL- and TSST-1-positive ST22-SCCmec IV isolates in mastitis-infected bovine milk highlights the need for persistent monitoring to mitigate possible public health risks. IMPORTANCE This study reports on the presence and characteristics of methicillin-resistant Staphylococcus aureus strains in milk from mastitis-infected cows. To our knowledge, this is the first report of a Panton-Valentine leukocidin- and toxic shock syndrome toxin-1-positive ST22-SCCmec IV strain in South Korea. | Kang, Hye Jeong; You, Ju-Yeon; Kim, Seung Hoe; Moon, Jin-San; Kim, Ha-Young; Kim, Jae-Myeong; Lee, Young Ju; Kang, Hyun-Mi | Anim & Plant Quarantine Agcy, Gimcheon, South Korea; Kyungpook Natl Univ, Coll Vet Med, Inst Vet Biomed Sci, Daegu, South Korea | Kim, So-Young/JFS-7698-2023 | 57208791752; 59463453600; 59350395800; 57212516440; 53877655700; 59467135100; 56612134500; 7404070907 | youngju@knu.ac.kr;greenkang@korea.kr; | MICROBIOLOGY SPECTRUM | 2165-0497 | 12 | 12 | 0.6 | 2025-05-07 | 1 | 1 | MRSA; bovine mastitis; PVL; TSST-1; ST22; biofilm; virulence; genotyping; antimicrobial resistance | MULTIPLEX PCR; PHENOTYPIC CHARACTERIZATION; GENES; SUSCEPTIBILITY | antimicrobial resistance; biofilm; bovine mastitis; genotyping; MRSA; PVL; ST22; TSST-1; virulence | ampicillin; antibiotic agent; antiinfective agent; cefoxitin; ceftriaxone; ciprofloxacin; clindamycin; cotrimoxazole; erythromycin; fusidic acid; gentamicin; kanamycin; leukocidin; macrolide; mecA gene; mupirocin; novobiocin; oxacillin; tetracycline; tiamulin; toxic shock syndrome toxin 1; unclassified drug; vancomycin; virulence factor; antibiotic resistance; antibiotic sensitivity; Article; bacterial gene; bacterial virulence; bacterium identification; bacterium isolate; bacterium isolation; biofilm; biofilm formation testing; bovine; bovine mastitis; bovine mastitis milk; comparative genomics analysis; dairy cattle; genetic variability; genotype; genotyping; infection control; mass spectrometry; mastitis; methicillin resistant Staphylococcus aureus; microtiter plate assay; molecular characteristic; molecular epidemiology; molecular phylogeny; molecular typing; motor unit potential; multidrug resistance; multilocus sequence typing; multiplex polymerase chain reaction; nonhuman; phenotype; phylogenetic tree; phylogeny; polymerase chain reaction; quality control; Staphylococcus aureus; Staphylococcus epidermidis; virulence; whole genome sequencing | English | 2024 | 2024-12-05 | 10.1128/spectrum.01197-24 | 바로가기 | 바로가기 | 바로가기 |
