| ○ | ○ | Proceedings Paper | Acoustic Metastructure-Lensed Multi-Focal Sonicator Designs for High-Throughput Therapeutic Ultrasound Testing In Vitro | We developed a custom multi-focal sonicator for high-throughput in vitro benchtop testing for micro/nanoagent-mediated ultrasound therapies. As biocompatible micro/nanoagents show significant therapeutic potential, optimizing ultrasound excitation conditions is essential. Traditional single-focus ultrasound setups face issues like beam alignment errors, long test times, and condition variations. To address these limitations, we designed a multi-focal sonicator generating uniform pressure across a 4x4 circular array. Using the acoustic hologram technique and iterative angular spectrum approach, we created a lens-interchangeable sonicator adaptable to different test plate sizes. After 70 iterations, simulations revealed a precise 4x4 focal array with a -6 dB lateral beam size of 1.4 mm. We prototyped both the lens and a sonicator bath with a flat-aperture transducer. Hydrophone measurements confirmed a multi-focal pressure pattern similar to simulations, with a structural similarity of 0.45 and cross-correlation of 0.78. The peak-negative pressures ranged from 1.5 to 1.7 MPa, averaging 1.62 MPa under an 800 V (peak-to-peak) burst input. Output intensities (SPTA) ranged from 0.5 W/cm(2) to 10.2 W/cm(2) with duty cycles from 0.5% to 12%. This device offers precise control and uniformity, enabling high-throughput benchtop studies on sonoporation and ultrasound-triggered drug release. | Kim, Jinwook; Kasoji, Sandeep; Dayton, Paul A. | Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea; Tirangle Biotechnol Inc, Chapel Hill, NC USA; Univ North Carolina Chapel Hill, Joint Dept Biomed Engn, Chapel Hill, NC USA; NC State Univ, Chapel Hill, NC USA | 55932101000; 56415126000; 7006230860 | jinwookkim@knu.ac.kr;sunny.kasoji@trianglebio.com;padayton@email.unc.edu; | 2024 IEEE ULTRASONICS, FERROELECTRICS, AND FREQUENCY CONTROL JOINT SYMPOSIUM, UFFC-JS 2024 | 1099-4734 | 0 | 2025-05-07 | 0 | 0 | Acoustic holograms; metastructure; acoustic lens; ultrasonics; transducer; sonicator | HOLOGRAMS; BRAIN | Acoustic holograms; acoustic lens; metastructure; sonicator; transducer; ultrasonics | Acoustic emission testing; Acoustic holography; Controlled drug delivery; Electron holography; Electron lenses; Targeted drug delivery; Ultrasonic testing; Ultrasonic transducers; Acoustic hologram; High-throughput; In-vitro; Metastructures; Sonicator; Therapeutic potentials; Therapeutic ultrasound; Ultrasound excitation; Ultrasound testing; Ultrasound therapy; Holograms | English | 2024 | 2024 | 10.1109/uffc-js60046.2024.10794123 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||

| ○ | ○ | Proceedings Paper | Active Heading Planning for Improving Visual-Inertial Odometry | Visual-inertial odometry (VIO) is a technique to estimate the motion of a vehicle platform by fusing camera and inertial sensor data. It operates effectively in GPS-denied environments such as indoors and is widely utilized in applications like autonomous navigation of unmanned aerial vehicles (UAVs) due to its real-time performance and high localization accuracy. However, since VIO relies on textures in the environment or features extracted from image frames, localization may easily fail if the number of feature points in the image is insufficient or the UAV faces a low-texture environment. To address these issues, we propose an active VIO algorithm by planning heading angles autonomously. This algorithm improves VIO accuracy and maintains robust localization even in an unknown environment by employing heading planning to acquire more feature points in the subsequent image frames. To achieve this, we first divide an image frame into several sections and count the number of feature points in each section. Next, we determine the desired heading angle based on the feature-occupied ratio of each section. The proposed approach is validated in various cases in a simulation environment that mimics an indoor warehouse. | Lee, Joohyuk; Lee, Kyuman | Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu 41566, South Korea | lee, kyuman/AAM-6979-2020 | 59202680300; 57193932345 | klee400@knu.ac.kr; | 2024 INTERNATIONAL CONFERENCE ON UNMANNED AIRCRAFT SYSTEMS, ICUAS | 2373-6720 | 0 | 2025-04-16 | 0 | 0 | Air navigation; Antennas; Image enhancement; Aerial vehicle; Autonomous navigation; Camera sensor; Heading angles; Image frames; Inertial sensor; Localisation; Odometry; Sensors data; Vehicle platforms; Textures | English | 2024 | 2024 | 10.1109/icuas60882.2024.10556967 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Review | Acute generalized exanthematous pustulosis caused by dihydrocodeine or codeine: A case-based review | Dihydrocodeine is an effective antitussive agent that inhibits the cough reflex by interacting with opioid receptors in the brain. It is easily available in pharmacies without a prescription, which may contribute to a lack of awareness about potential drug hypersensitivity reactions. In the first reported case in Korea, a 29-year-old man developed acute generalized exanthematous pustulosis (AGEP) after consuming an over-the-counter cold medicine containing dihydrocodeine. He was admitted to the Emergency Department with high fever and full-body skin rashes that appeared 3 hours after taking the medicine. His EuroSCAR AGEP score was 9, with symptoms improving upon discontinuation of dihydrocodeine and the application of topical steroids. AGEP caused by dihydrocodeine, including codeine, is very rare, with 3 cases reported worldwide. By analyzing AGEP cases due to dihydrocodeine or codeine, we identified that risk factors for the development of AGEP from dihydrocodeine include a history of psoriasis and the presence of an IL36RN mutation, which result in the activation ofTh17 in the blood or the skin. In cases of AGEP caused by dihydrocodeine, it is also recommended to discontinue codeine due to cross-reactivity with dihydrocodeine. Additionally, patients with AGEP due to dihydrocodeine may be able to use other opioid classes, such as morphine or tramadol, due to low cross-reactivity.

| ○ | Conference paper | Adaptive People Counting and Localization Based on Meta Learning with WiFi NICs | The paper focuses on utilizing channel state information (CSI) from commodity WiFi network interface cards (NICs) for people counting and localization systems. CSI offers informative data on signal characteristics in amplitude and phase, but it is prone to offsets by hardware imperfection and co-channel interference from other WiFi devices. The paper introduces a preprocessing method to remove offsets, ensuring low-latency operation without additional filtering. Then, we propose people counting and localization models that are based on meta learning to adapt to different environments. Numerical results demon-strate the effectiveness of the proposed meta learning models in achieving high sensing accuracy compared to other simpler training methods. © 2024 IEEE. | Cha, Jihoon; Kim, Hwanjin; Choi, Junil | School of Electrical Engineering, Korea Advanced Institute of Science and Technology, Daejeon, South Korea; School of Electronics Engineering, Kyungpook National University, Daegu, South Korea; School of Electrical Engineering, Korea Advanced Institute of Science and Technology, Daejeon, South Korea | 57219591658; 57204105066; 59722155200 | charge@kaist.ac.kr;junil@kaist.ac.kr; | Conference Record - Asilomar Conference on Signals, Systems and Computers | 1058-6393 | 0 | 2025-05-07 | 0 | Channel state information; Cochannel interference; Wi-Fi; Channel-state information; Co-channel interferences; Counting system; Localisation; Localisation Systems; Metalearning; Network interface cards; People counting; Signal characteristic; Wi Fi networks; Wireless local area networks (WLAN) | English | Final | 2024 | 10.1109/ieeeconf60004.2024.10942994 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Adhesion of Technical Lignin-Based Non-Isocyanate Polyurethane Adhesives for Wood Bonding | Lignin is the most abundant aromatic natural polymer, and receiving great attention in replacing various petro-leum-based polymers. The aim of this study is to investigate the feasibility of technical lignin as a polyol for the synthesis of non-isocyanate polyurethane (NIPU) adhesives to substitute current polyurethane (PU) adhesives that have been synthesized with toxic isocyanate and polyols. Crude hardwood kraft lignin (C-HKL) was extracted from black liquor from a pulp mill followed by acetone fractionation to obtain acetone soluble-HKL (AS-HKL). Then, C-HKL, AS-HKL, and softwood sodium lignosulfonate (LS) were used for the synthesis of technical lignin-based NIPU adhesives through carbonation and polyamination and silane as a cross-linker. Their adhesion performance was determined for plywood. FTIR spectra showed the formation of urethane bonds and the reaction between lignin and silane. The NIPU adhesives prepared with C-HKL showed the highest adhesion strength among the three lignin-based NIPU adhesives. As the silane addition level increased, the adhesion strength of NIPU adhesives increased whereas formaldehyde emission decreased for all NIPU adhesives prepared. These results indicate that NIPU adhesives based on technical kraft lignin have a great potential as polyol for the synthesis of bio-based NIPU adhesives for wood bonding. © 2024, Tech Science Press.

As semiconductor devices shrink and become more complex, the accuracy of defect detection becomes crucial. This paper traces the evolution from manual inspections to the use of advanced technologies such as automated vision systems, artificial intelligence (AI), and machine learning (ML). It discusses various defects like crystallographic errors, surface anomalies, and chemical impurities that affect device functionality and longevity, emphasizing the need for precise identification. The shift to ML and deep learning (DL) represents a significant move towards more adaptive, accurate, and faster detection methods. The paper outlines challenges like the miniature scale of modern devices, high costs of advanced imaging technologies, and the need speed in mass production. It identifies a critical gap between current technological capabilities and industry needs, particularly in scalability and processing throughput. Future research directions are suggested to close these gaps, including enhancing AI computational efficiency, developing new materials for better imaging contrast, and integrating these technologies seamlessly into production lines. This synthesis of current technologies and exploration of future trends aims to advance the dialogue and development of more effective defect detection and classification methods, leading to the production of more reliable semiconductor devices. © 2024 IEEE. | Zheng, Yuxun; Chee, K.-W.A. | School of Electronic and Electrical Engineering, Kyungpook National University, Next-Generation Intelligent Semiconductor Energy Engineering and Analysis Laboratory, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, Next-Generation Intelligent Semiconductor Energy Engineering and Analysis Laboratory, Daegu, 41566, South Korea | 58762678700; 57524559900 | 2024 International Convention on Rehabilitation Engineering and Assistive Technology and World Rehabilitation Robot Convention, WRRC 2024 - Proceedings | 0 | 2025-05-07 | 0 | Carrier concentration; Computer debugging; Crystal impurities; Semiconductor devices; Component efficiencies; Component reliability; Current technology; Defect classification; Defect detection; Defect detection method; Electronic component; Future trends; Machine-learning; Technology trends | English | Final | 2024 | 10.1109/wrrc62201.2024.10696150 | 바로가기 | 바로가기 | ||||||||||||||||||||
| ○ | Article | Aed-net: Attention-based detection model for disabled signage detection | The aim of having designated parking spaces for individuals with disabilities is to ensure that only vehicles with proper handicapped signage use them, while preventing unauthorized vehicles from occupying those spaces. To achieve this, real-time monitoring is essential. Existing two-stage object detection models suffer from slow image processing and enhanced backbones with feature pyramid networks are also burdened with expanded parameters. While YOLOv5 model is a compelling choice due to its superior speed and performance compared to existing models. Therefore, this study proposes to make certain modifications to a baseline YOLOv5 model. Instead of the original 9 blocks in the backbone and 4 C3 blocks, we propose to replace them with 6 and 4 EfficientNet blocks, accordingly. These EfficientNet blocks have fewer parameters but still offer higher accuracy in detecting disabled signs, among other types of signs on car windshields. To make up for the reduced number of blocks, we have incorporated an attention mechanism into the proposed architecture before the detection phase. This mechanism enables the model to focus on the crucial regions required for the task. Furthermore, we propose utilizing a more advanced optimizer called AdamW to prevent overfitting. With these enhancements, a novel object detector, attention-based efficient detection model (AED-Net) is proposed. To assess the effectiveness of the proposed approach, we will gather and label a dataset comprising images of cars displaying disabled signage on their windshields. Experiments conducted using this dataset demonstrate that the proposed model achieves a superior F1 score of 0.73 compared to that of baseline model, 0.57. The proposed model utilizes 10 percent fewer parameters compared to the baseline model. © 2024, Korean Institute of Communications and Information Sciences.

| ○ | ○ | Proceedings Paper | AERO: Adaptive Erase Operation for Improving Lifetime and Performance of Modern NAND Flash-Based SSDs | This work investigates a new erase scheme in NAND flash memory to improve the lifetime and performance of modern solid-state drives (SSDs). In NAND flash memory, an erase operation applies a high voltage (e.g., > 20 V) to flash cells for a long time (e.g., > 3.5 ms), which degrades cell endurance and potentially delays user I/O requests. While a large body of prior work has proposed various techniques to mitigate the negative impact of erase operations, no work has yet investigated how erase latency should be set to fully exploit the potential of NAND flash memory; most existing techniques use a fixed latency for every erase operation which is set to cover the worst-case operating conditions. To address this, we propose AERO (Adaptive ERase Operation), a new erase scheme that dynamically adjusts erase latency to be just long enough for reliably erasing target cells, depending on the cells' current erase characteristics. AERO accurately predicts such near-optimal erase latency based on the number of fail bits during an erase operation. To maximize its benefits, we further optimize AERO in two aspects. First, at the beginning of an erase operation, AERO attempts to erase the cells for a short time (e.g., 1 ms), which enables AERO to always obtain the number of fail bits necessary to accurately predict the near-optimal erase latency. Second, AERO aggressively yet safely reduces erase latency by leveraging a large reliability margin present in modern SSDs. We demonstrate the feasibility and reliability of AERO using 160 real 3D NAND flash chips, showing that it enhances SSD lifetime over the conventional erase scheme by 43% without change to existing NAND flash chips. Our system-level evaluation using eleven real-world workloads shows that an AERO-enabled SSD reduces read tail latency by 34% on average over a state-of-the-art technique. | Cho, Sungjun; Kim, Beomjun; Cho, Hyunuk; Seo, Gyeongseob; Mutlu, Onur; Kim, Myungsuk; Park, Jisung | POSTECH, Pohang Si, South Korea; Kyungpook Natl Univ, Daegu, South Korea; Swiss Fed Inst Technol, Zurich, Switzerland | 57217212078; 58958257600; 57743131700; 16043006700; 56095781900; 57336554900; 57194859467 | allencho1222@postech.ac.kr;beomjun0816@knu.ac.kr;gusdnr9779@postech.ac.kr;syhbong9@knu.ac.kr;omutlu@gmail.com;ms.kim@knu.ac.kr;jisung.park@postech.ac.kr; | PROCEEDINGS OF THE 29TH ACM INTERNATIONAL CONFERENCE ON ARCHITECTURAL SUPPORT FOR PROGRAMMING LANGUAGES AND OPERATING SYSTEMS, VOL 3, ASPLOS 2024 | 1.78 | 2025-05-07 | 3 | 2 | solid state drives (SSDs); NAND flash memory; erase operation; SSD lifetime; I/O performance | erase operation; I/O performance; NAND flash memory; solid state drives (SSDs); SSD lifetime | Memory architecture; NAND circuits; Erase operation; Flash chips; High-voltages; I/O performance; NAND Flash; NAND flash memory; Near-optimal; Performance; Solid state drive; Solid state drive lifetime; Flash-based SSDs | English | 2024 | 2024 | 10.1145/3620666.3651341 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Conference paper | AI-enabled smart LSCI system for early diagnosis of diabetic foot ulcers | Diabetic foot ulcers (DFU) are open sores or wounds that develop on the feet of people with diabetes. They are a serious complication and often occur on the bottom of the foot. DFU treatment in the field of medical sciences is an advanced field of study. Patients with DFU have a five-year death rate of approximately 40%. Age, gender, medical history, vascular diseases, and renal illness are major risk factors for mortality. While 90% of people with diabetes worldwide have type 2 diabetes mellitus, accounting for 463 million cases of the disease. DFU diagnosis and treatment has been performed with Laser Speckle Contrast Imaging (LSCI) which is a non-invasive imaging technology. LSCI is becoming widely recognized as a vital technique for evaluating the impacts and implications of this disease. Major types of LSCI has been studied for the application of laser speckle technology in medical diagnosis. Region of Interest (ROI) and Multi exposure based LSCI applications and implementations has been reviewed in this study. Along with the application of conventional LSCI, Artificial Intelligence (AI) tools has been studied for robust results to combat issues associated with diabetes. © 2024 SPIE. | Aqeel-Ur-Rehman; Noureen, Sadia; Cabrera, Humberto; Khaliq, Hafiz Saad; Mehmood, Muhammad Qasim; Zubair, Muhammad | Department of Electrical Engineering, Information Technology University of the Punjab (ITU), Lahore, 54000, Pakistan; Department of Electrical Engineering, Information Technology University of the Punjab (ITU), Lahore, 54000, Pakistan; MLab, STI Unit, The Abdus Salam International Centre for Theoretical Physics, Strada Costiera 11, Trieste, 34151, Italy; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Department of Electrical Engineering, Information Technology University of the Punjab (ITU), Lahore, 54000, Pakistan; Innovative Technologies Laboratories (ITL), King Abdullah University of Science and Technology (KAUST), Thuwal, 23955, Saudi Arabia | 59385280200; 57808658700; 14832333900; 56725698200; 56276474100; 56581448000 | Proceedings of SPIE - The International Society for Optical Engineering | 0277-786X | 13006 | 0 | 2025-05-07 | 0 | Biomedical imaging; Diabetes mellitus; Laser speckle contrast imaging (LSCI); Microcirculation; Non-invasive imaging | Diagnosis; Diseases; Image segmentation; Medical imaging; Speckle; Biomedical imaging; Death rates; Diabetes mellitus; Diabetic foot ulcer; Early diagnosis; Laser speckle contrast imaging; Medical history; Medical science; Non-invasive imaging; Microcirculation | English | Final | 2024 | 10.1117/12.3022044 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Conference paper | Airborne Cross-infection Risk Under Different Body Orientations in an Air-conditioned Room | This study aims to investigate airborne cross-infection risk based on different body orientations (face-to-face, side-by-side, and back-to-back), with varying air discharge angles (-20°, 0°, and +20°) and air temperatures (18 and 30 ℃) from an air conditioner. In this study, experiments were conducted in a full-scale test chamber using two manikins and simulated particles (NaCl). The cross-infection risk was initially high in the face-to-face position, and in the side-by-side position after 20 min, without air conditioner operation. With the operation of the air conditioner, the overall cross-infection risk was highest in the face-to-face position and lowest in the back-to-back position; however, after installing the partition, the back-to-back and side-by-side positions showed a high cross-infection risk. The results indicated that under the same distance between two individuals and indoor airflow conditions, body orientation was a crucial factor influencing the cross-infection risk. © 2024 18th Conference of the International Society of Indoor Air Quality and Climate, INDOOR AIR 2024 - Conference Program and Proceedings.

| ○ | Review | Allergic rhinitis and hygiene hypothesis | The hygiene hypothesis, first proposed in 1989, suggested that reduced exposure to infections in early life leads to allergic diseases by the defects in the establishment of immune tolerance. Although many studies provided evidence that some exposure conditions, including family size, antibiotics, probiotics, and viral or bacterial infections, are strongly related to the prevalence of allergic diseases, thereby supporting the hygiene hypothesis, some evidence does not provide acceptable results for the hygiene hypothesis. Further, most studies have focused on patients with asthma or atopic dermatitis, not allergic rhinitis. In this review, we summarize the recent studies for and against the 'hygiene hypothesis' and identify causal association with the prevalence of allergic rhinitis. | Jee, Hye Mi; Kim, Minji; Kim, Hyun Hee; Kim, Hyo-Bin; Rha, Yeong-Ho; Park, Yang; Sung, Myongsoon; Shin, Youn Ho; Yum, Hye Yung; Lee, Kyung Suk; Lee, Yong Ju; Chun, Yoon Hong; Choi, Bong Seok; Choi, Sun Hee; Park, Yong Mean | CHA Univ, Sch Med, CHA Bundang Med Ctr, Dept Pediat, Seongnam, South Korea; Chungnam Natl Univ, Chungnam Natl Univ Sejong Hosp, Coll Med, Dept Pediat, Sejong, South Korea; Catholic Univ Korea, Coll Med, Dept Pediat, Seoul, South Korea; Inje Univ, Sanggye Paik Hosp, Dept Pediat, Seoul, South Korea; Kyung Hee Univ, Sch Med, Dept Pediat, Seoul, South Korea; Wonkwang Univ, Jangheung Integrat Med Hosp, Sch Med, Jangheung, South Korea; Soonchunhyang Univ, Dept Pediat, Gumi Hosp, Gumi, South Korea; CHA Univ, CHA Gangnam Med Ctr, Dept Pediat, Sch Med, Seoul, South Korea; Seoul Med Ctr, Dept Pediat, Seoul, South Korea; Hanyang Univ, Guri Hosp, Coll Med, Guri, South Korea; Yonsei Univ, Yongin Severance Hosp, Coll Med, Yongin, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Konkuk Univ, Med Ctr, Sch Med, Dept Pediat, 120-1 Neungdong Ro, Seoul 05030, South Korea | Lee, JongGu/B-7384-2013; Yum, Hye Yung/HNS-1098-2023; Patthipati, Venkata Suresh/AAT-8233-2021; Rha, Yeong/AAI-9767-2020 | pymcko@gmail.com; | ALLERGY ASTHMA & RESPIRATORY DISEASE | 2288-0402 | 2288-0410 | 12 | 1 | 0 | Allergy; Hygiene hypothesis; Allergic rhinitis | RISK-FACTORS; EARLY-LIFE; PRIMARY PREVENTION; DOUBLE-BLIND; HAY-FEVER; ASTHMA; CHILDREN; PREVALENCE; PROBIOTICS; EXPOSURE | English | 2024 | 2024-01 | 10.4168/aard.2024.12.1.3 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Ambrosiella catenulata Isolated from Ambrosia Beetles in Korean Apple Orchards | A fungus was isolated from ambrosia beetles collected using beetle traps in an apple orchard in Gunwi-gun, Daegu, South Korea. This fungal strain was termed ARI-24-A5, and was identified through morphological characterization and molecular phylogenetic analysis. After 8 d of incubation on potato dextrose agar (PDA), ARI-24-A5 exhibited gray-to-olive coloration, abundant aerial mycelia, and a colony diameter of 72.0–79.0 mm. Morphologically, the aleurioconidiophores formed monilioid chain structures, and the size of the aleurioconidia was 11.1 × 10.8 μm. For precise identification, molecular phylogenetic analysis was performed using the internal transcribed spacer (ITS) region, translation elongation factor 1-alpha (TEF1-α), small subunit of nuclear ribosomal RNA (SSU), and RNA polymerase II subunit 1 (RPB1) gene sequences. The overall analysis confirmed that ARI-24-A5 belongs to the genus Ambrosiella, which is known for its symbiotic relationship with ambrosia beetles. In the phylogenetic tree, ARI-24-A5 shared the same taxonomic position as A. catenulata and its morphological characteristics were consistent with those of this species. Therefore, ARI-24-A5 was identified as A. catenulata, making this the first record of this species in South Korea. © 2024 THE KOREAN SOCIETY OF MYCOLOGY. | Lee, Ju-Heon; Kim, Youngsoo; Park, Jong-Taek; Lee, Dong-Hyuk; Jung, Hee-Young | Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea, Department of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Department of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea | 57735778800; 59501674100; 57189052808; 57221245349; 7403029383 | heeyoung@knu.ac.kr; | Korean Journal of Mycology | 0253-651X | 52 | 4 | 0 | 2025-05-07 | 0 | Ambrosia beetle; Ambrosiella catenulata; Korean apple orchard; Symbiotic fungi | English | Final | 2024 | 10.4489/kjm.520416 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Ambrosiella roeperi: An Unreported Fungus Isolated from Ambrosia Beetles | In this study, ambrosia beetles were collected using insect traps in Gunwi-gun, Daegu-si, South Korea, to investigate symbiotic fungi associated with beetles. Fungi were isolated from the collected beetles. Among the isolates, a strain obtained from Ambrosiodmus rubricollis was designated as ARI-24-A4. Cultural and molecular biological analyses confirmed that ARI-24-A4 belongs to Ambrosiella. Key morphological characteristics, including the structure of the conidiophores and the size of aleurioconidia (av. 12.9 μm × 12.5 μm), were examined to accurately identify the Ambrosiella species. A phylogenetic tree was constructed by combining the internal transcribed spacer (ITS) region, translation elongation factor 1-alpha (TEF1-α), and small subunit of nuclear ribosomal RNA (SSU) gene sequences to confirm the phylogenetic position. The strain was verified to share the same phylogenetic position as Ambrosiella roeperi. Therefore, ARI-24-A4 was confirmed to be A. roeperi, a species previously unreported in Korea. It has been recorded as a newly identified species in the country. © 2024 THE KOREAN SOCIETY OF MYCOLOGY. | Lee, Ju-Heon; Kim, YoungSoo; Ten, Leonid N.; Park, Jong-Taek; Lee, Dong-Hyuk; Jung, Hee-Young | Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea, Department of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Institute of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Apple Research Center, National Institute of Horticultural & Herbal Science, Gunwi, 43100, South Korea; Department of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea, Institute of Plant Medicine, Kyungpook National University, Daegu, 41566, South Korea | 57735778800; 59501674100; 6603039265; 57189052808; 57221245349; 7403029383 | heeyoung@knu.ac.kr; | Korean Journal of Mycology | 0253-651X | 52 | 4 | 0.64 | 2025-05-07 | 1 | Ambrosia beetles; Ambrosiella roeperi; Phylogeny; Symbiotic | English | Final | 2024 | 10.4489/kjm.520403 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Book chapter | Amoxicillin | Treatment of Helicobacter pylori (H. pylori) is warranted and normally done with combination of antibiotics (such as amoxicillin, clarithromycin, or others) and a proton pump inhibitor. However, the eradication rate of legacy triple therapy has been decreasing because of the increase in resistance to clarithromycin. Likewise, treatment failure due to amoxicillin, a primary antimicrobial agent for H. pylori eradication, resistance has been noted since 20 years ago. Increasing levels of resistance to amoxicillin contribute to treatment failures, and higher levels of resistance are believed to be due to multiple genetic mutations. However, the exact mechanism of amoxicillin resistance and its contribution to eradication failure has not been fully elucidated. © Springer Nature Singapore Pte Ltd. 2023.
