| ○ | ○ | Article | Independent isomeric yield ratios of fission products in the epi-cadmium neutron induced fission of ²³⁵U | In the epi-cadmium neutron induced fission of U-235, independent isomeric yield ratios (IR) of fission products Sb-130,Sb-132, Te-131,Te-133, I-134,I-136, Xe-135 and Cs-138 have been measured by using an off-line gamma-ray spectrometric technique. The average neutron energy of the epi-cadmium reactor neutron spectrum is 1.9 MeV. From the IR values, the root mean square fragment angular momenta (JRMS) were deduced by using spin dependent statistical model analysis. The IR and JRMS values of considered fission products in the epi-cadmium neutron induced fission of U-235 were compared with the literature data in the thermal neutron induced fission of U-235 to examine the influence of excitation energy on nuclear structure effect. | Naik, H.; Singh, R.

| ○ | ○ | Article | Optimization of smoothing parameter for block matching and 3D filtering algorithm in low-dose chest and abdominal computed tomography images | Computed tomography (CT), known for its exceptionally high accuracy, is associated with a substantial dose of ionizing radiation. Low -dose protocols have been devised to address this issue; however, a reduction in the radiation dose can lead to a deficiency in the number of photons, resulting in quantum noise. Thus, the aim of this study was to optimize the smoothing parameter (u -value) of the block matching and 3D filtering (BM3D) algorithm to effectively reduce noise in low -dose chest and abdominal CT images. Acquired images were subsequently analyze using quantitative evaluation metrics, including contrast to noise ratio (CNR), coefficient of variation (CV), and naturalness image quality evaluator (NIQE). Quantitative evaluation results demonstrated that the optimal u -value for CNR, CV, and NIQE were 0.10, 0.11, and 0.09 in low -dose chest CT images respectively, whereas those in abdominal images were 0.12, 0.11, and 0.09, respectively. The average of the optimal u -values, which produced the most improved results, was 0.10, considering both visual and quantitative evaluations. In conclusion, we demonstrated that the optimized BM3D algorithm with u -value is effective for noise reduction in low -dose chest and abdominal CT images indicating its feasibility of in the clinical field. | Park, Minji; Lim, Sewon; Kim, Hajin; Kim, Jae -Young; Lee, Youngjin | Gachon Univ, Dept Hlth Sci, Gen Grad Sch, Incheon, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Biochem, IHBR, Daegu, South Korea; Gachon Univ, Dept Radiol Sci, 191 Hambakmoe Ro, Incheon 21936, South Korea | Kim, Jae-Young/IUO-6466-2023 | 57215211537; 58648127500; 58648468900; 56812734700; 36064226600 | yj20@gachon.ac.kr; | APPLIED RADIATION AND ISOTOPES | APPL RADIAT ISOTOPES | 0969-8043 | 1872-9800 | 210 | SCIE | CHEMISTRY, INORGANIC & NUCLEAR;NUCLEAR SCIENCE & TECHNOLOGY;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 1.8 | 40.2 | 0 | 2025-05-07 | 0 | 0 | Computed tomography; Block matching and 3D filtering (BM3D); algorithm; Optimization of u-value; Quantitative evaluation | NOISE-REDUCTION; CT | Block matching and 3D filtering (BM3D) algorithm; Computed tomography; Optimization of σ-value; Quantitative evaluation | Algorithms; Humans; Imaging, Three-Dimensional; Phantoms, Imaging; Radiation Dosage; Radiography, Abdominal; Radiography, Thoracic; Signal-To-Noise Ratio; Tomography, X-Ray Computed; Computerized tomography; Image denoising; Image quality; Ionizing radiation; Motion compensation; Noise abatement; Parameter estimation; Quality control; Abdominal computed tomographies; Block matching and 3d filtering; Block matching and 3d filtering algorithm; Computed tomography; Computed tomography images; Filtering algorithm; Low dose; Optimisations; Optimization of σ-value; Quantitative evaluation; abdomen; adult; algorithm; article; benchmarking; computer assisted tomography; contrast to noise ratio; controlled study; female; filtration; human; image quality; ionizing radiation; low drug dose; male; noise; noise reduction; photon; protocol; radiation dose; thorax; abdominal radiography; imaging phantom; procedures; radiation dose; signal noise ratio; thorax radiography; three-dimensional imaging; x-ray computed tomography; Quantum noise | English | 2024 | 2024-08 | 10.1016/j.apradiso.2024.111374 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Quadratic resampling method for the long-term y-ray background spectra using an HPGe detector | We developed a novel quadratic resampling method for summing up y-ray spectra with different calibration parameters. We investigated a long-term environmental background y-ray spectrum by summing up 114 spectra measured using a 30% HPGe detector between 2017 and 2021. Gain variations in different measurement periods shift y-ray peak positions by a fractional pulse-height bin size up to around 2 keV. The resampling method was applied to measure low-level background y-ray peaks in the y-ray spectrum in a wide energy range from 50 keV to 3 MeV. We additionally document temporal variations in the activities of major yray peaks, such as 40 K (1461 keV), 208 Tl (2615 keV), and other typical nuclides, along with contributions from cosmic rays. The normal distribution of y-ray background count rates, as evidenced by quantile-quantile plots, indicates consistent data collection throughout the measurement period. Consequently, we assert that the quadratic resampling method for accumulating y-ray spectra surpasses the linear method (Bossew, 2005) in various aspects. | Kim, using Suhyun; Kim, Shin Hyung; Ahn, Jung Keun; Nam, Seung-il | PKNU, Inst Radiat Sci & Technol IRST, Busan 48513, South Korea; Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Korea Univ, Dept Phys, Seoul 02841, South Korea; Pukyong Natl Univ PKNU, Dept Phys, Busan 48513, South Korea | Kim, Sulhee/HLW-9057-2023 | 58884924800; 56673366800; 7403019450; 7402275945 | sinam@pknu.ac.kr; | APPLIED RADIATION AND ISOTOPES | APPL RADIAT ISOTOPES | 0969-8043 | 1872-9800 | 210 | SCIE | CHEMISTRY, INORGANIC & NUCLEAR;NUCLEAR SCIENCE & TECHNOLOGY;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2024 | 1.8 | 40.2 | 0.52 | 2025-05-07 | 0 | 1 | Long-term y-ray backgrounds; Quadratic resampling methods; HPGe detector; Calibration curve; Log-normal quantile plot | SPECTROMETRY; URANIUM | Calibration curve; HPGe detector; Log-normal quantile plot; Long-term γ-ray backgrounds; Quadratic resampling methods | Calibration; Cosmic rays; Cosmology; Germanium compounds; Normal distribution; Ultraviolet spectroscopy; potassium 40; radon; Background spectrum; Calibration curves; HPGe detectors; Log-normal; Log-normal quantile plot; Long-term γ-ray background; Quadratic resampling method; Quantile plots; Resampling method; Spectra's; algorithm; Article; calibration; cosmic radiation; gamma radiation; gamma spectrometry; linear system; normal distribution; radiation energy; article; calibration; human; radiation detector; Gamma rays | English | 2024 | 2024-08 | 10.1016/j.apradiso.2024.111341 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A nanoscale surface engineered magneto-mechano-triboelectric nanogenerator enabled by reliable pattern replication for self-powered IoT devices | The present work demonstrates a high-performance magneto-mechano-triboelectric nanogenerator (MMTENG) by utilizing a reliable pattern replication process to harvest electric energy from a magnetic field for powering Internet of Things (IoT) devices. This process enables the formation of a nanoscale structure on a triboelectric polymer film for improving contact triboelectrification and electrostatic induction. The surface-patterned MMTENG achieves a high open-circuit peak-to-peak voltage (Vpp = 521 V), short-circuit current (Imax = 177 mu A), and maximum peak power (Pmax = 7 mW) under an 8 Oe magnetic field, which is 4.6 times higher than that of a non-patterned MMTENG device (Pmax = 1.5 mW). The harvested electric power from the MMTENG device is utilized to operate an IoT environmental (temperature and humidity) monitoring sensor. This paper provides a nanoscale surface-replicated magneto-mechano-triboelectric nanogenerator (MMTENG) for demonstration of a self-powered IoT system. | Pattipaka, Srinivas; Park, Tae Wan; Bae, Young Min; Na, Yujin; Chung, Kyeongwoon; Park, Kwi-Il; Ryu, Jungho; Park, Woon Ik; Hwang, Geon-Tae | Pukyong Natl Univ, Dept Mat Sci & Engn, 45 Yongso Ro, Busan 48513, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Biofibers & Biomat Sci, Daegu 41566, South Korea; Yeungnam Univ, Sch Mat Sci & Engn, Daehak Ro, Gyongsan 38541, Gyeongsangbuk D, South Korea | Na, Yujin/LFT-4103-2024; Park, Kwiil/LKN-9445-2024; Pattipaka, Srinivas/P-2993-2019; Ryu, Jungho/LXU-4081-2024 | 57189258366; 57189896587; 58000755400; 57566141800; 56416916000; 35280874200; 57201603501; 53980463200; 36704574900 | thane0428@pknu.ac.kr;gthwang@pknu.ac.kr; | SUSTAINABLE ENERGY & FUELS | SUSTAIN ENERG FUELS | 2398-4902 | 8 | 3 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 4.1 | 40.3 | 1.94 | 2025-05-07 | 12 | 12 | GENERATOR; INTERNET; THINGS; SOLAR | Electrostatics; Internet of things; Magnetic fields; Magnetos; Polymer films; Semiconducting films; Triboelectricity; Electric energies; Magnetic-field; Nano-scale surfaces; Nanogenerators; Nanoscale structure; Pattern replication; Performance; Replication process; Self-powered; Triboelectrification; equipment; magnetic field; nanotechnology; performance assessment; polymer; Nanogenerators | English | 2024 | 2024-01-30 | 10.1039/d3se01206a | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Probiotic Feed Additives Mitigate Odor Emission in Cattle Farms through Microbial Community Changes | Odor emissions from animal manure present a significant environmental challenge in livestock farming, impacting air quality and farm sustainability. Traditional methods, such as chemical additives and manure treatment, can be costly, labor-intensive, and less eco-friendly. Therefore, this study investigated the effectiveness of microbial feed additives in reducing these odors. Conducted over three months in 2022 on a Korean beef cattle farm with 20 cattle, the experiment involved feeding a mixture of four microbial strains-Bacillus subtilis KNU-11, Lactobacillus acidophilus KNU-02, Lactobacillus casei KNU-12, and Saccharomyces cerevisiae KNU-06. Manure samples were collected from an experimental group (n = 9) and a control group (n = 11), with microbial community changes assessed through 16S ribosomal RNA gene amplicon sequencing. The results demonstrated significant reductions in specific odorous compounds in the experimental group compared to the control group: ammonia decreased by 64.1%, dimethyl sulfide by 81.3%, butyric acid by 84.6%, and isovaleric acid by 49.8%. Additionally, there was a notable shift in the microbiome, with an increase in the relative abundance of Ruminococcaceae and Prevotellaceae microbes associated with fiver degradation and fermentation, while the control group had higher levels of Bacteroidota and Spirochaetota, which are linked to pathogenicity. This study demonstrates that probiotics effectively alter intestinal microbiota to enhance microorganisms associated with odor mitigation, offering a promising and more sustainable approach to reducing odor emissions in livestock farming. | Park, Min-Kyu; Hwang, Tae-Kyung; Kim, Wanro; Jo, Youngjae; Park, Yeong-Jun; Kim, Min-Chul; Son, Hyunwoo; Seo, DaeWeon; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU NGS Core Facil, Daegu 41566, South Korea; Microbalance Inc, Daegu 41566, South Korea; Gunwi Agr Technol Ctr, Gunwi Gun 43126, Daegu, South Korea | Son, Hyunwoo/ABC-5701-2020 | 7404490480; 57214872881; 58091232100; 57214743390; 56275800900; 57203466596; 57218872919; 59347856000; 57224125922 | pmk601313@mabals.com;jhshin@knu.ac.kr; | FERMENTATION-BASEL | FERMENTATION-BASEL | 2311-5637 | 10 | 9 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2024 | 3.3 | 40.4 | 0.49 | 2025-05-07 | 1 | 1 | environmental emission reduction; livestock odor control; microbial intervention; sustainable agriculture; ruminant gut health | FERMENTATION; HEALTH; FIBER; SWINE | environmental emission reduction; livestock odor control; microbial intervention; ruminant gut health; sustainable agriculture | English | 2024 | 2024-09 | 10.3390/fermentation10090473 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | RFWBS Model: Multilevel Hybrid Mapping Solution Framework for Designing Neurorehabilitation Physiotherapy Devices | Healthcare services and rehabilitation equipment have entered a phase of rapid development driven by user requirements. However, the development of corresponding design models for rehabilitation equipment is lacking. A general framework and development process are urgently needed for neurorehabilitation physiotherapy equipment. To address problems such as inadequate knowledge representation in the design process and difficulties in modeling the functional structure of the product, we combined a decomposition topology model of neurorehabilitation physiotherapy equipment with the modular design method. We proposed a general model for the design of neurorehabilitation physiotherapy equipment comprising the following modules: requirements (R), function (F), principle workspace (W), behavior (B), and structure (S), i.e., the RFWBS model. Using the neurorehabilitation robotic glove as an example for design practice, in terms of kinematics, the mechanism is analyzed by establishing a Lagrangian coordinate system for resolution. The mechanism has three degrees of freedom and can achieve the natural flexion and extension angles of each finger joint. In terms of dynamics, during the entire finger extension, the angular acceleration is almost zero, and the average angular velocity is approximately 30 similar to 50 degrees/s. This indicates that the mechanism is suitable for wearable use, validating the scientific and effective nature of the RFWBS expanded model. | Zhang, Peng; Jiang, Nan; Lee, Kyoung Yong; Yu, Jinxu; Han, Xin | Kyungpook Natl Univ, Dept Design, Daegu 41566, South Korea; Yanshan Univ, Sch Art & Design, Qinhuangdao 066004, Peoples R China; Yanshan Univ, Sch Mech Engn, Key Lab Adv Forging & Stamping Technol & Sci, Qinhuangdao 066004, Peoples R China; Kyungpook Natl Univ, Dept Landscape Architecture, Daegu 41566, South Korea | Lee, KyoungYong/AFP-2697-2022 | 58247542600; 58246707200; 58246924400; 56809701700; 57716224500 | 2021327350@knu.ac.kr;2021327070@knu.ac.kr;tryyong@naver.com;yujinxu@stumail.ysu.edu.cn;2021327318@knu.ac.kr; | MACHINES | MACHINES | 2075-1702 | 12 | 1 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;ENGINEERING, MECHANICAL | 2024 | 2.5 | 40.4 | 0 | 2025-04-16 | 0 | 0 | RFWBS model; multilevel hybrid mapping solution; neurorehabilitation physiotherapy equipment design; design process model | KNOWLEDGE REPRESENTATION; PRODUCT DESIGN; REHABILITATION | design process model; multilevel hybrid mapping solution; neurorehabilitation physiotherapy equipment design; RFWBS model | English | 2024 | 2024-01 | 10.3390/machines12010043 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Synthesis of H∞ Control for Descriptor Hybrid Systems with Actuator Saturation | This paper addresses a mode-dependent state-feedback H-infinity control for stochastic descriptor hybrid systems, considering both the absence and presence of actuator saturation. Firstly, the necessary and sufficient conditions for the stochastic admissibility criterion with H-infinity performance gamma of the closed-loop system are proposed. Given the proposed non-convex condition, the author reformulates it into linear matrix inequalities (LMIs). Then, to extend the result to the systems with actuator saturation, the actuator-saturated control input is expressed as a linear combination of a given state-feedback control input and a virtual control input that always remains under the saturation level. To verify this expression, the set invariant condition is also suggested by using the singular mode-dependent Lyapunov function candidate. Therefore, the conditions for the existence of both the mode-dependent state-feedback H-infinity control and the ellipsoidal shape invariant sets are successfully derived in terms of LMIs. Two numerical examples demonstrate the effectiveness of the proposed method by solving optimization problems subject to the proposed LMIs that minimize H-infinity performance gamma and maximize the invariant set, respectively. | Park, Chan-eun | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57001658700 | chaneun@knu.ac.kr; | MACHINES | MACHINES | 2075-1702 | 12 | 1 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;ENGINEERING, MECHANICAL | 2024 | 2.5 | 40.4 | 0 | 2025-04-16 | 0 | 0 | descriptor system; hybrid system; stochastic system; H-infinity control; input saturation; set invariant | MARKOVIAN JUMP SYSTEMS; OUTPUT-FEEDBACK CONTROL; STABILIZATION; SUBJECT | descriptor system; H<sub>∞</sub> control; hybrid system; input saturation; set invariant; stochastic system | English | 2024 | 2024-01 | 10.3390/machines12010038 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Investigating soil physicochemical factors influencing trace element contamination at the semi-urban-rural home gardening interfaces on the Fiji Islands | Due to its ecological and public health implications, home gardening soil pollution is challenging. However, the physicochemical factors of trace element pollution in semi-urban-rural home gardening soil interfaces in Fiji are unclear. Self-organizing map (SOM), chemometrics, compositional data analysis (CDA), and soil quality indices were used to evaluate spatial patterns, contamination characteristics, sources, and factors affecting trace element contamination in 55 soil samples from semi-urban and rural Fiji. The average contents of diethylenetriaminepentaacetic acid (DTPA)-extractable forms of trace element levels (mg/kg) increased in rural areas as Fe (55.7) > Mn (40.4) > Zn (9.4) > Cu (5.9) and semi-urban areas as Fe (55.2) > Zn (35.9) > Mn (37.1) > Cu (16.1). Rural soils have less ecological risks to home gardening than semi-urban soils. SOM and CDA analysis showed four spatial clusters: clusters 1 and 3 are natural geogenic in rural regions while clusters 2 and 4 are human-induced non-point sources in semi-urban areas. Principal component analysis (PCA) and hierarchical cluster analysis showed that semi-urban Cu-Zn was more affected by manufacturing emissions or fertilization, whereas rural Fe-Mn was more likely to be lithogenic. The research found that pH and organic matter significantly affect Cu and Zn pollution in semi-urban soils (p < 0.05). For rural and semi-urban soils, trace element subsets explained 44 %-87 % of soil contamination changes using the stepwise regression model. These findings aid to establishing a primary database of eco-environmental risks and facilitate comprehensive strategies for assessing soil contamination and potential threats to food safety. | Chand, Vimlesh; Islam, Abu Reza Md Towfiqul; Mia, Md Yousuf; Islam, Md Saiful; Al Masud, Md Abdullah; Khan, Rahat; Pal, Subodh Chandra; Singh, Sudhir Kumar; Deo, Rozleen Roslyn | Fiji Natl Univ, Coll Engn & Tech Vocat Educ & Training, Sch Sci, Suva, Fiji; Begum Rokeya Univ, Dept Disaster Management, Rangpur 5400, Bangladesh; Daffodil Int Univ, Dept Dev Studies, Dhaka 1216, Bangladesh; Patuakhali Sci & Technol Univ, Dept Soil Sci, Dumki 8602, Patuakhali, Bangladesh; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Bangladesh Atom Energy Commiss BAEC, Inst Nucl Sci & Technol, Dhaka 1349, Bangladesh; Univ Burdwan, Dept Geog, Bardhaman 713104, West Bengal, India; Univ Allahabad, Nehru Sci Ctr, IIDS, K Banerjee Ctr Atmospher & Ocean Studies, Prayagraj 211002, India; Minist Agr, Crop Res Div, Koronivia Res Stn, Nausori, Fiji; Korea Univ, Coll Sci, Dept Earth & Environm Sci, 145 Anam Ro, Seoul 02841, South Korea | Masud, Md Abdullah Al/JEF-1055-2023; Islam, Md/ABB-2487-2021; Chand, Vimlesh/AAB-6479-2020; Islam, Abu/AAN-8105-2020 | 25922064100; 57218543677; 58142281600; 55547120952; 57542255300; 56501271600; 57208776491; 57198063860; 59370720500 | vimlesh.c@fnu.ac.fj;towfiq_dm@brur.ac.bd;masudsao@gmail.com; | GEODERMA REGIONAL | GEODERMA REG | 2352-0094 | 39 | SCIE | SOIL SCIENCE | 2024 | 3.3 | 40.6 | 0 | 2025-05-07 | 3 | 4 | Self-organizing map; Ecological risk; Eco-environmental treats; Chemometrics; Fiji | HEAVY-METAL CONTAMINATION; POTENTIAL ECOLOGICAL RISK; SOURCE IDENTIFICATION; AGRICULTURAL SOILS; HEALTH-RISKS; COASTAL AREA; QUALITY; POLLUTION; SEDIMENTS; DISTRICT | Chemometrics; Eco-environmental treats; Ecological risk; Fiji; Self-organizing map | English | 2024 | 2024-12 | 10.1016/j.geodrs.2024.e00884 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Biomechanical Gait Analysis Using a Smartphone-Based Motion Capture System (OpenCap) in Patients with Neurological Disorders | This study evaluates the utility of OpenCap (v0.3), a smartphone-based motion capture system, for performing gait analysis in patients with neurological disorders. We compared kinematic and kinetic gait parameters between 10 healthy controls and 10 patients with neurological conditions, including stroke, Parkinson's disease, and cerebral palsy. OpenCap captured 3D movement dynamics using two smartphones, with data processed through musculoskeletal modeling. The key findings indicate that the patient group exhibited significantly slower gait speeds (0.67 m/s vs. 1.10 m/s, p = 0.002), shorter stride lengths (0.81 m vs. 1.29 m, p = 0.001), and greater step length asymmetry (107.43% vs. 91.23%, p = 0.023) compared to the controls. Joint kinematic analysis revealed increased variability in pelvic tilt, hip flexion, knee extension, and ankle dorsiflexion throughout the gait cycle in patients, indicating impaired motor control and compensatory strategies. These results indicate that OpenCap can effectively identify significant gait differences, which may serve as valuable biomarkers for neurological disorders, thereby enhancing its utility in clinical settings where traditional motion capture systems are impractical. OpenCap has the potential to improve access to biomechanical assessments, thereby enabling better monitoring of gait abnormalities and informing therapeutic interventions for individuals with neurological disorders. | Min, Yu-Sun; Jung, Tae-Du; Lee, Yang-Soo; Kwon, Yonghan; Kim, Hyung Joon; Kim, Hee Chan; Lee, Jung Chan; Park, Eunhee | Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Rehabil Med, Daegu 41404, South Korea; Kyungpook Natl Univ, Grad Sch Comp Sci & Engn, AI Driven Convergence Software Educ Res Program, Daegu 41566, South Korea; Seoul Natl Univ, Coll Med, Dept Biomed Engn, Seoul 03080, South Korea; Kyungpook Natl Univ Hosp, Dept Rehabil Med, Daegu 41944, South Korea; Seoul Natl Univ, Grad Sch, Interdisciplinary Program Bioengn, Seoul 08826, South Korea; Seoul Natl Univ, Inst Bioengn, Seoul 03080, South Korea; Seoul Natl Univ, Inst Med & Biol Engn, Med Res Ctr, Seoul 03080, South Korea | Kim, Hee Chan/J-5455-2012; Lee, Jung/A-9253-2011; Lee, Jung Chan/A-9253-2011 | 48061349800; 36622364500; 57202952463; 59345303300; 59345085400; 57213118053; 37960940900; 56107216400 | ssuni119@naver.com;teeed0522@hanmail.net;leeyangsoo@knu.ac.kr;k55054103@gmail.com;rlagudwns8851@naver.com;hckim@snu.ac.kr;ljch@snu.ac.kr;ehmdpark@naver.com; | BIOENGINEERING-BASEL | BIOENGINEERING-BASEL | 2306-5354 | 11 | 9 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 3.7 | 40.7 | 0.8 | 2025-05-07 | 4 | 4 | gait; kinematics; kinetics; motion capture; smartphone | gait; kinematics; kinetics; motion capture; smartphone | English | 2024 | 2024-09 | 10.3390/bioengineering11090911 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Deep Learning Method for Precise Landmark Identification and Structural Assessment of Whole-Spine Radiographs | This study measured parameters automatically by marking the point for measuring each parameter on whole-spine radiographs. Between January 2020 and December 2021, 1017 sequential lateral whole-spine radiographs were retrospectively obtained. Of these, 819 and 198 were used for training and testing the performance of the landmark detection model, respectively. To objectively evaluate the program's performance, 690 whole-spine radiographs from four other institutions were used for external validation. The combined dataset comprised radiographs from 857 female and 850 male patients (average age 42.2 +/- 27.3 years; range 20-85 years). The landmark localizer showed the highest accuracy in identifying cervical landmarks (median error 1.5-2.4 mm), followed by lumbosacral landmarks (median error 2.1-3.0 mm). However, thoracic landmarks displayed larger localization errors (median 2.4-4.3 mm), indicating slightly reduced precision compared with the cervical and lumbosacral regions. The agreement between the deep learning model and two experts was good to excellent, with intraclass correlation coefficient values >0.88. The deep learning model also performed well on the external validation set. There were no statistical differences between datasets in all parameters, suggesting that the performance of the artificial intelligence model created was excellent. The proposed automatic alignment analysis system identified anatomical landmarks and positions of the spine with high precision and generated various radiograph imaging parameters that had a good correlation with manual measurements. | Noh, Sung Hyun; Lee, Gaeun; Bae, Hyun-Jin; Han, Ju Yeon; Son, Su Jeong; Kim, Deok; Park, Jeong Yeon; Choi, Seung Kyeong; Cho, Pyung Goo; Kim, Sang Hyun; Yuh, Woon Tak; Lee, Su Hun; Park, Bumsoo; Kim, Kwang-Ryeol; Kim, Kyoung-Tae; Ha, Yoon | Ajou Univ, Coll Med, Dept Neurosurg, Suwon 16499, South Korea; Yonsei Univ, Coll Med, Dept Neurosurg, Seoul 03722, South Korea; Promedius Inc, Seoul 05609, South Korea; Hallym Univ Hwaseong, Dongtan Sacred Heart Hosp, Dept Neurol Surg, Hwaseong si 18450, South Korea; Pusan Natl Univ, Yangsan Hosp, Dept Neurosurg, Yangsan 50612, South Korea; Bon Hosp, Dept Neurosurg, Daejeon 34188, South Korea; Daegu Catholic Univ, Dept Neurosurg, Coll Med, Taegu 42400, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Neurosurg, Daegu 41944, South Korea; Yonsei Univ, Severance Hosp, Spine & Spinal Cord Inst, Dept Neurosurg,Coll Med, Seoul 03722, South Korea | lee, suhun/IXD-7443-2023; Bae, Hyun-Jin/J-8037-2015; Lee, Hye/J-2154-2015 | 57194978247; 57205528361; 51563162500; 59141941000; 59141942900; 59141750300; 59141160900; 59141358400; 56366637100; 57202337309; 57191359268; 57195611959; 59141556200; 57226848552; 57201369790; 55736636500 | juwuman12@gmail.com; | BIOENGINEERING-BASEL | BIOENGINEERING-BASEL | 2306-5354 | 11 | 5 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 3.7 | 40.7 | 0.8 | 2025-05-07 | 2 | 3 | artificial intelligence; deep learning; radiography; spine | artificial intelligence; deep learning; radiography; spine | English | 2024 | 2024-05 | 10.3390/bioengineering11050481 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Toward Interpretable Cell Image Representation and Abnormality Scoring for Cervical Cancer Screening Using Pap Smears | Screening is critical for prevention and early detection of cervical cancer but it is time-consuming and laborious. Supervised deep convolutional neural networks have been developed to automate pap smear screening and the results are promising. However, the interest in using only normal samples to train deep neural networks has increased owing to the class imbalance problems and high-labeling costs that are both prevalent in healthcare. In this study, we introduce a method to learn explainable deep cervical cell representations for pap smear cytology images based on one-class classification using variational autoencoders. Findings demonstrate that a score can be calculated for cell abnormality without training models with abnormal samples, and we localize abnormality to interpret our results with a novel metric based on absolute difference in cross-entropy in agglomerative clustering. The best model that discriminates squamous cell carcinoma (SCC) from normals gives 0.908 +/- 0.003 area under operating characteristic curve (AUC) and one that discriminates high-grade epithelial lesion (HSIL) 0.920 +/- 0.002 AUC. Compared to other clustering methods, our method enhances the V-measure and yields higher homogeneity scores, which more effectively isolate different abnormality regions, aiding in the interpretation of our results. Evaluation using an external dataset shows that our model can discriminate abnormality without the need for additional training of deep models. | Ando, Yu; Cho, Junghwan; Park, Nora Jee-Young; Ko, Seokhwan; Han, Hyungsoo | Kyungpook Natl Univ, Dept Biomed Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Clin Om Inst, Daegu 41405, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu 41944, South Korea; Kyunpook Natl Univ, Dept Pathol, Chilgok Hosp, Daegu 41404, South Korea | ; Cho, Junghwan/AAK-4752-2020 | 57295299200; 57424663500; 57226185359; 57205603624; 7401969388 | yuando@knu.ac.kr;joshua@knu.ac.kr;pathpjy@knu.ac.kr;skanny@knu.ac.kr;hshan@knu.ac.kr; | BIOENGINEERING-BASEL | BIOENGINEERING-BASEL | 2306-5354 | 11 | 6 | SCIE | ENGINEERING, BIOMEDICAL | 2024 | 3.7 | 40.7 | 0.8 | 2025-05-07 | 4 | 5 | cervical cancer screening; deep learning; variational autoencoders; clustering | cervical cancer screening; clustering; deep learning; variational autoencoders | English | 2024 | 2024-06 | 10.3390/bioengineering11060567 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | An enhanced graph convolutional network with property fusion for acupoint recommendation | Acupuncture therapy, rooted in traditional Chinese medicine (TCM), plays a pivotal role in both disease treatment and preventive health care. A significant challenge within this realm is precise acupoint recommendations tailored to specific symptoms, with consideration of the intricate inherent relationships between the symptoms and acupoints. Traditional recommendation methods encounter another difficulty in grappling with the sparse nature of TCM data. To address these issues, we present a novel approach called the enhanced graph convolutional network with property fusion (PEGCN), which consists of two key components, the property feature graph encoder module and the enhanced graph convolutional network module. The former extracts property knowledge of acupoints to enrich their representations. The latter integrates the GCN structure and an attention mechanism to efficiently capture the underlying relationships between symptoms and acupoints. In this paper, we apply the PEGCN model to a real-world dataset related to acupuncture therapy, and the experimental results demonstrate its superiority over the baseline models in terms of the evaluation metrics, which include Precision@K, Recall@K, and NDCG@K. This finding suggests that our model effectively addresses the challenges associated with acupoint recommendations, offering an improved method for personalized treatments in the TCM context. | Li, Ruiling; Wu, Song; Tu, Jinyu; Peng, Limei; Ma, Li | Hubei Univ Chinese Med, Coll Informat Engn, Wuhan 430065, Hubei, Peoples R China; Hubei Univ Chinese Med, Coll Acupuncture Moxibust & Orthoped, Wuhan 430065, Hubei, Peoples R China; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | 58087406400; 56161566600; 59297954400; 59510719200; 58452680000 | mary0807@hbucm.edu.cn; | APPLIED INTELLIGENCE | APPL INTELL | 0924-669X | 1573-7497 | 54 | 22 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE | 2024 | 3.5 | 40.9 | 0.8 | 2025-05-07 | 2 | 3 | Acupoint recommendation; Graph convolutional network; Representation learning; Attention mechanism | Acupoint recommendation; Attention mechanism; Graph convolutional network; Representation learning | Acupuncture; Convolutional neural networks; Medicinal chemistry; Personalized medicine; Acupoint recommendation; Acupoints; Acupuncture therapy; Attention mechanisms; Convolutional networks; Disease treatment; Graph convolutional network; Property; Representation learning; Traditional Chinese Medicine; Disease control | English | 2024 | 2024-11 | 10.1007/s10489-024-05792-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Developing veterinary basic clinical skill items based on Korean Veterinary Entrustable Professional Activity | Importance: Developing clinical skills is an essential element of veterinary education to ensure the competency of veterinary graduates. Although the Korean Veterinary Education Graduation Competencies were established in 2016, reflecting domestic needs and international trends in competency-based veterinary education, they have yet to be implemented in Korean veterinary education. Objective: This study aimed to establish the basic veterinary clinical skills required to ensure graduates of Korean veterinary universities have the day-one competency to independently perform their professional duties. Methods: The Education Committee of the Korean Association of Veterinary Medical Colleges, composed of veterinary school professors and an experienced veterinarian in the clinic, reviewed domestic and international veterinary education-related materials to define basic clinical skills. Results: The Korean Veterinarian Entrustable Professional Activities (KVEPA) was introduced, followed by the subsequent development of 54 essential clinical skills based on the KVEPA. Conclusions and Relevance: The veterinary basic clinical skills established through this study can be used as a specific guide for clinical education in Korean veterinary school, and is expected to play an important role in meeting the needs of the educational sector of the veterinary education accreditation standards. | Lee, Kichang; Lee, Heungshik S.; Jeong, Seong Mok; Kang, Jongil; Kim, Seungjoon; Chung, Jin-Young; Nahm, Sang-Soep; Ryu, Pan Dong | Korean Assoc Vet Med Coll, Council Educ, Seoul 08826, South Korea; Jeonbuk Natl Univ, Coll Vet Med, Vet Clin, Iksan 54596, South Korea; Seoul Natl Univ, Coll Vet Med, Seoul 08826, South Korea; Chungnam Natl Univ, Coll Vet Med, Dept Vet Surg, Daejeon 34134, South Korea; Choonghyun Anim Hosp, Seoul 06122, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Theriogenol, Daegu 41566, South Korea; Kangwon Natl Univ, Coll Vet Med, Dept Vet Internal Med, Chunchon 24341, South Korea; Konkuk Univ, Coll Vet Med, Dept Vet Anat, 120 Neungdong Ro, Seoul 05029, South Korea | 7501513678; 59349589000; 7402425314; 58309611400; 55718678200; 56809978700; 7005150720; 56569308600 | ssnahm@konkuk.ac.kr; | JOURNAL OF VETERINARY SCIENCE | J VET SCI | 1229-845X | 1976-555X | 25 | 5 | SCIE | VETERINARY SCIENCES | 2024 | 1.5 | 40.9 | 0 | 2025-05-07 | 0 | 0 | Competence; day one skill; veterinary education | UNDERGRADUATE MEDICAL-EDUCATION; FRAMEWORK; MODEL | Competence; day one skill; veterinary education | Clinical Competence; Competency-Based Education; Education, Veterinary; Republic of Korea; Schools, Veterinary; Veterinarians; accreditation; article; clinical education; diagnosis; medical school; nonhuman; open access publishing; skill; veterinarian; veterinary education; veterinary medicine; clinical competence; curriculum; school; South Korea | English | 2024 | 2024-09 | 10.4142/jvs.24129 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of platelet-rich plasma in Achilles tendon allograft in rabbits | Background: Achilles tendon is composed of dense connective tissue and is one of the largest tendons in the body. In veterinary medicine, acute ruptures are associated with impact injury or sharp trauma. Healing of the ruptured tendon is challenging because of poor blood and nerve supply as well as the residual cell population. Platelet-rich plasma (PRP) contains numerous bioactive agents and growth factors and has been utilized to promote healing in bone, soft tissue, and tendons. Objective: The purpose of this study was to evaluate the healing effect of PRP injected into the surrounding fascia of the Achilles tendon after allograft in rabbits. Methods: Donor rabbits (n = 8) were anesthetized and 16 lateral gastrocnemius tendons were fully transected bilaterally. Transected tendons were decellularized and stored at -80 degrees C prior to allograft. The allograft was placed on the partially transected medial gastrocnemius tendon in the left hindlimb of 16 rabbits. The allograft PRP group (n = 8) had 0.3 mL of PRP administered in the tendon and the allograft control group (n = 8) did not receive any treatment. After 8 weeks, rabbits were euthanatized and allograft tendons were transected for macroscopic, biomechanical, and histological assessment. Results: The allograft PRP group exhibited superior macroscopic assessment scores, greater tensile strength, and a histologically enhanced healing process compared to those in the allograft control group. Conclusions: Our results suggest administration of PRP on an allograft tendon has a positive effect on the healing process in a ruptured Achilles tendon. | Park, Seok-Hong; Kim, Dong-Yub; Lee, Won -Jae; Jang, Min; Jeong, Seong Mok; Ku, Sae-Kwang; Kwon, Young -Sam; Yun, Sungho | Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Chungnam Natl Univ, Coll Vet Med, Dept Vet Surg, Daejeon 34134, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Anat & Histol, Gyongsan 38610, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Surg, 80 Daehak Ro, Daegu 41566, South Korea | 58980864200; 57211343808; 57205486455; 55341507600; 7402425314; 7006331005; 7403459426; 57201366734 | Shyun@knu.ac.kr; | JOURNAL OF VETERINARY SCIENCE | J VET SCI | 1229-845X | 1976-555X | 25 | 2 | SCIE | VETERINARY SCIENCES | 2024 | 1.5 | 40.9 | 0 | 2025-04-16 | 0 | 0 | Achilles tendon; allograft; platelet-rich plasma; rabbit | GROWTH-FACTORS; STIMULATION; COLLAGEN; RUPTURES | Achilles tendon; allograft; platelet-rich plasma; rabbit | Achilles Tendon; Allografts; Animals; Platelet-Rich Plasma; Rabbits; Tendon Injuries; Wound Healing; achilles tendon; animal experiment; animal model; Article; biomechanics; controlled study; decellularization; gastrocnemius muscle; histology; immunohistochemistry; Leporidae; morphometry; nonhuman; outcome assessment; tendon graft; tendon rupture; tensile strength; therapy effect; thrombocyte rich plasma; allograft; animal; Leporidae; pathology; surgery; tendon injury; veterinary medicine; wound healing | English | 2024 | 2024-03 | 10.4142/jvs.23281 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
