| ○ | ○ | Article | Effect of Heat Treatment on Mechanical Properties of Nickel-Titanium Instruments | Introduction: The aim of this study was to evaluate the torsional resistance, cyclic fatigue resistance, and bending stiffness of nickel -titanium (NiTi) file systems with different heat treatments and cross-sectional designs. Methods: WaveOne Primary treated with memorytriple (MT) heat treatment (WOMT) was compared with WaveOne Primary (WO) and WaveOne Gold Primary (WOG). Torsional resistance test was performed using a customized device, and the distortion angle, ultimate strength, and toughness were evaluated. For cyclic fatigue resistance test, the instruments were reciprocated with continuous 4 mm up -and -down movement until fracture in a customized device, and the time to fracture was compared. Fracture surfaces of each group were examined under the scanning electron microscope. Bending stiffness was measured using a custom-made device. The results were analyzed using one-way analysis of variance and the Tukey's post hoc comparison at a significance level of 95%. Results: WOMT showed higher ultimate strength and toughness than the other systems (P < .05). WOMT also showed highest cyclic fatigue resistance among the tested groups (P < .05). WO had the highest bending stiffness than others, whereas WOMT had a larger residual angle than others (P < .05). Conclusions: This new MT heat treatment technique makes NiTi file more flexible and improves its mechanical properties. In addition, the effect of heat treatment on flexibility was found to be more significant than that of the crosssectional area.

| ○ | ○ | Article | Effect of MT Technology of Heat Treatment on Reciproc: Comparison of Reciproc, Reciproc Blue, and Reciproc MT | Introduction: This study aimed to evaluate the effects from the memory-triple (MT) heat treatment on the fatigue resistance of the Reciproc by comparison with the file systems of same geometry. Methods: Reciproc files subjected to MT heat treatment technology were designated as Group RMT and were compared with the original Reciproc (Group REC) and Reciproc Blue (Group REB). Each NiTi file from 3 groups (n 5 15) was operated reciprocally with a repetitive up-and-down movement in the curved canal with 4 mm of pecking distance inside of the simulated canal at body temperature. When each file fractured, the time until fracture was recorded. The length of the fractured fragment was measured. Fractured fragments were observed under scanning electron microscope (SEM) to evaluate the topographic features of the surface. Differential scanning calorimetry (DSC) analysis was performed to estimate phase transformation temperatures. One-way analysis of variance and Duncan post hoc comparison were applied to compare among the groups at a significance level of 95%. Results: RMT showed significantly higher fracture resistance (P , .05), whereas there was no difference in fatigue resistance between REC and REB. SEM examination showed the files from the 3 groups had similar topographic features. RMT showed a peak of austenite peak (Ap) at a temperature (52 degrees C) higher than body temperature, whereas REC and REB showed Ap at 37 and 32 degrees C, respectively. Conclusions: Under the condition of this study, the new heat treatment technique of MT technology could enhance the fatigue fracture resistance of the reciprocating files made of M-wire and Blue-wire.

| ○ | ○ | Article | Effects of Side Flattening on Torsional and Cyclic Fracture Resistance of Nickel-Titanium File | Introduction: The purpose of this study was to evaluate the effect of side flattening of cutting flutes on the cyclic resistance and torsional resistance of nickel -titanium files. Methods: Both novel flattened Platinum V.EU (PL) and standard nonflattened CC Premium V.EU (CC) rotaries were tested. For cyclic fatigue tests, all the files were rotated in an artificial root canal with a curvature of 45 degrees and a radius of 6.06 mm at 300 rpm (n 5 15 in each group). The number of cycles to failure (NCF) was calculated. For torsional tests, the files were rotated at 2 rpm clockwise until fracture occurred. The maximum torque value at fracture was measured and the toughness and distortion angle were computed. Subsequently, 5 fragments were randomly selected in each experiment, the cross-section and longitudinal direction of the fragments were photographed using a scanning electron microscope. An unpaired t -test was performed at a significance level of 95%. Results: There was a statistically significant difference in NCF between CC and PL (P , .05). CC showed higher NCF than PL. There was no statistically significant difference between CC and PL with regards to the parameters related to torsional resistance (distortion angle, ultimate strength, and toughness) (P . .05). Conclusion: Within the limitations of this study, side flattening of the file did not improve cyclic resistance or torsional resistance of the files. As side flattening may reduce a file's cyclic resistance, such files should be used with caution in clinical practice.

| ○ | ○ | Article | Human-airway surface mesh smoothing based on graph convolutional neural networks | Background and Objective: A detailed representation of the airway geometry in the respiratory system is critical for predicting precise airflow and pressure behaviors in computed tomography (CT)-image-based computational fluid dynamics (CFD). The CT-image-based geometry often contains artifacts, noise, and discontinuities due to the so-called stair step effect. Hence, an advanced surface smoothing is necessary. The existing smoothing methods based on the Laplacian operator drastically shrink airway geometries, resulting in the loss of information related to smaller branches. This study aims to introduce an unsupervised airway-mesh-smoothing learning (AMSL) method that preserves the original geometry of the three-dimensional (3D) airway for accurate CT-image-based CFD simulations. Method: The AMSL method jointly trains two graph convolutional neural networks (GCNNs) defined on airway meshes to filter vertex positions and face normal vectors. In addition, it regularizes a combination of loss functions such as reproducibility, smoothness and consistency of vertex positions, and normal vectors. The AMSL adopts the concept of a deep mesh prior model, and it determines the self-similarity for mesh restoration without using a large dataset for training. Images of the airways of 20 subjects were smoothed by the AMSL method, and among them, the data of two subjects were used for the CFD simulations to assess the effect of airway smoothing on flow properties. Results: In 18 of 20 benchmark problems, the proposed smoothing method delivered better results compared with the conventional or state-of-the-art deep learning methods. Unlike the traditional smoothing, the AMSL successfully constructed 20 smoothed airways with airway diameters that were consistent with the original CT images. Besides, CFD simulations with the airways obtained by the AMSL method showed much smaller pressure drop and wall shear stress than the results obtained by the traditional method. Conclusions: The airway model constructed by the AMSL method reproduces branch diameters accurately without any shrinkage, especially in the case of smaller airways. The accurate estimation of airway geometry using a smoothing method is critical for estimating flow properties in CFD simulations. | Ho, Thao Thi; Tran, Minh Tam; Cui, Xinguang; Lin, Ching -Long; Baek, Stephen; Kim, Woo Jin; Lee, Chang Hyun; Jin, Gong Yong; Chae, Kum Ju; Choi, Sanghun | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea; Huazhong Univ Sci & Technol, Sch Aerosp Engn, Wuhan, Peoples R China; Univ Iowa, Dept Mech Engn, IIHR Hydrosci & Engn, Iowa, IA USA; Univ Virginia, Sch Data Sci, Charlottesville, VA USA; Univ Virginia, Dept Mech & Aerosp Engn, Charlottesville, VA USA; Kangwon Natl Univ, Kangwon Natl Univ Hosp, Dept Internal Med & Environm Hlth Ctr, Sch Med, Chunchon, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Radiol, Seoul, South Korea; Univ Iowa, Coll Med, Dept Radiol, Iowa, IA USA; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Dept Radiol, Res Inst Clin Med,Biomed Res Inst, Jeonju, South Korea | Tran, Minh Tam/KDN-3469-2024; Baek, Stephen/A-6316-2016; Choi, Sanghun/AGS-7430-2022; Kim, Woo/A-8216-2019; Baek, Stephen/GXH-9181-2022 | 57221374670; 58770600000; 50261346800; 8923593300; 57191200449; 56560422500; 57196253438; 55663719500; 57195310676; 55847101000 | s-choi@knu.ac.kr; | COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE | COMPUT METH PROG BIO | 0169-2607 | 1872-7565 | 246 | SCIE | COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;COMPUTER SCIENCE, THEORY & METHODS;ENGINEERING, BIOMEDICAL;MEDICAL INFORMATICS | 2024 | 4.8 | 13.3 | 0.72 | 2025-05-07 | 2 | 2 | Surface mesh smoothing; Deep mesh prior; Graph convolutional neural network; Computed tomography; Computational fluid dynamics | BREATHING LUNG MODEL; FLOW; SIMULATION | Computational fluid dynamics; Computed tomography; Deep mesh prior; Graph convolutional neural network; Surface mesh smoothing | Computer Simulation; Humans; Lung; Neural Networks, Computer; Reproducibility of Results; Surgical Mesh; Air; Computerized tomography; Convolution; Convolutional neural networks; Deep neural networks; Graph neural networks; Large datasets; Learning systems; Mathematical operators; Mesh generation; Respiratory system; Shear stress; Computational fluid dynamics simulations; Computed tomography; Computed tomography images; Convolutional neural network; Deep mesh prior; Graph convolutional neural network; Image-based; Learning methods; Mesh smoothing; Surface mesh smoothing; Article; computer assisted tomography; convolutional neural network; human; shear stress; three dimensional computer aided design; three-dimensional imaging; artificial neural network; computer simulation; lung; reproducibility; Computational fluid dynamics | English | 2024 | 2024-04 | 10.1016/j.cmpb.2024.108061 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Impact of fleQ Deficiency on Resource Allocation and Heterologous Gene Expression in Pseudomonas putida Across Various Growth Media | Pseudomonas putida is widely used in industrial applications, including the recombinant proteins production, because of its natural advantageous properties. In this study, the gene encoding FleQ, the primary regulator of flagellar synthesis, was deleted to construct a new non-motile P. putida KT2440-derived strain (Delta fleQ). The non-motile cells showed reduced biofilm formation and enhanced expression of a heterologous gene in nutrient-rich media compared with the wild-type (WT) strain, attributed to the reallocation of cellular resources from flagellar synthesis and cellular motility. Additionally, the Delta fleQ strain exhibited enhanced tolerance to chloramphenicol, indicating higher ribosome production, confirmed by a higher RNA/protein ratio relative to the WT. While the WT strain showed decreased growth and a three-fold increase in reporter gene activity in minimal media, the Delta fleQ strain maintained consistent reporter gene expression and exhibited a relatively higher growth rate. This suggests that the FleQ is involved in modulating proteome allocation based on nutrient quality. The removal of FleQ allows for more flexible resource allocation, creating a chassis strain with nutrient quality-independent gene expression capacity, which could be valuable in industrial applications where consistent output is essential. | Kim, Junyoung; Lee, Sooyeon; Darlington, Alexander P.

| ○ | ○ | Article | A Kahler potential on the unit ball with constant differential norm | Let B-n be the unit ball in C-n and H-n be the homogeneous Siegel domain of the second kind which is biholomorphic to B-n. We show that the Kahler potential of H-n is unique up to the automorphisms among Kahler potentials whose differentials have constant norms. As an application, we consider a domain Omega in C-n, which is biholomorphic to B-n. We show that if Omega is affine homogeneous, then it is affine equivalent to H-n. Assume next that its canonical potential with respect to the Kahler-Einstein metric has a differential with a constant norm. If the biholomorphism between Omega and B-n is a restriction of a Mobius transformation, then the map is affine equivalent to a Cayley transform. | Lee, Kang-Hyurk; Seo, Aeryeong | Gyeongsang Natl Univ, Dept Math, Jinju 52828, Gyeongnam, South Korea; Gyeongsang Natl Univ, Res Inst Nat Sci, Jinju 52828, Gyeongnam, South Korea; Kyungpook Natl Univ, Dept Math, 80 Daehak Ro, Jinju 41566, Gyeongnam, South Korea | Seo, Aeryeong/GON-4707-2022 | 24460301300; 55266222700 | nyawoo@gnu.ac.kr;aeryeong.seo@knu.ac.kr; | MATHEMATISCHE ANNALEN | MATH ANN | 0025-5831 | 1432-1807 | 389 | 4 | SCIE | MATHEMATICS | 2024 | 1.4 | 13.4 | 0 | 2025-05-07 | 0 | 0 | English | 2024 | 2024-08 | 10.1007/s00208-023-02749-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Automatic Vision-Based Dump Truck Productivity Measurement Based on Deep-Learning Illumination Enhancement for Low-Visibility Harsh Construction Environment | Productivity assessment plays a key role in successful earthwork projects and is primarily achieved by monitoring key construction equipment such as excavators and dump trucks. Vision-based methods are widely adopted to analyze the productivity of construction equipment in earthwork projects. These methods are inexpensive and easy to implement and maintain. However, previous studies on vision-based productivity analysis of earthmoving equipment have predominantly demonstrated its effectiveness under favorable conditions characterized by stable lighting, areas devoid of shadows, and high-visibility environments free from significant occlusion by other objects or terrain. There is a significant illumination difference and limited visibility under harsh low-visibility conditions at earthwork construction sites, which makes it difficult to achieve reliable identification accuracy using these already developed methods. To address this problem, this study proposes an automatic vision-based dump truck productivity measurement method based on a deep learning illumination enhancement algorithm combined with transfer learning for low-visibility, harsh conditions at earthwork construction sites. This method uses an internet of things (IoT) system equipped with a camera to capture the image and a deep learning illumination enhancement algorithm, trainable deep hybrid network (TDHN), to enhance the image quality under low-light conditions at earthwork sites. Then, a deep convolutional neural network image recognition algorithm, ResNet50, was combined with a transfer learning technique to extract information from the image. Through the IoT, this processed information is sent to the earthwork platform to perform productivity analysis and make timely decisions regarding equipment allocation schemes. To validate the effectiveness of the proposed methodology, it was implemented in a real-time earthwork project. This study results show that image recognition accuracy of 99.6%, 95.67%, and 94.77% under normal lighting, low lighting, and extremely low lighting conditions, respectively. The dump truck recognition accuracy increased by 1.10%, 3.62%, and 21.19%, leading to a significant improvement in productivity measurement of 1.08%, 3.54%, and 20.71% for the above-mentioned lighting conditions, respectively. | Deng, Tao; Sharafat, Abubakar; Lee, Soomin; Seo, Jongwon | Hanyang Univ, Seoul 04763, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Sharafat, Abubakar/ITW-2048-2023 | jseo@hanyang.ac.kr; | JOURNAL OF CONSTRUCTION ENGINEERING AND MANAGEMENT | J CONSTR ENG M | 0733-9364 | 1943-7862 | 150 | 11 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;ENGINEERING, INDUSTRIAL | 2024 | 5.1 | 13.4 | 3 | Earthwork; Productivity; Internet of things (IoT); Convolutional neural network; Transfer learning; Image enhancement; Low visibility | EARTHMOVING EXCAVATORS; ACTION RECOGNITION; EQUIPMENT; FEATURES; NETWORK | English | 2024 | 2024-11-01 | 10.1061/jcemd4.coeng-14194 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | Characteristic of school injuries in Asia: a cross-national, multi-center observational study | Background: To prevent school injuries, thorough epidemiological data is an essential foundation. We aimed to investigate the characteristics of school injuries in Asia and explore risk factors for major trauma. Methods: This retrospective study was conducted in the participating centers of the Pan-Asian Trauma Outcome Study from October 2015 to December 2020. Subjects who reported “school” as the site of injury were included. Major trauma was defined as an Injury Severity Score (ISS) value of ≥16. Results: In total, 1305 injury cases (1.0% of 127,715 events) occurred at schools. Among these, 68.2% were children. Unintentional injuries were the leading cause and intentional injuries comprised 7.5% of the cohort. Major trauma accounted for 7.1% of those with documented ISS values. Multivariable regression revealed associations between major trauma and factors, including age, intention of injury (self-harm), type of injury (traffic injuries, falls), and body part injured (head, thorax, and abdomen). Twenty-two (1.7%) died, with six deaths related to self-harm. Females represented 28.4% of injuries but accounted for 40.9% of all deaths. Conclusions: In Asia, injuries at schools affect a significant number of children. Although the incidence of injuries was higher in males, self-inflicted injuries and mortality cases were relatively higher in females. Impact: Epidemiological data and risk factors for major trauma resulting from school injuries in Asia are lacking. This study identified significant risk factors for major trauma occurring at schools, including age, intention of injury (self-harm), injury type (traffic injuries, falls), and body part injured (head, thoracic, and abdominal injuries). Although the incidence of injuries was higher in males, the incidence of self-harm injuries and mortality rates were higher in females. The results of this would make a significant contribution to the development of prevention strategies and relative policies concerning school injuries. © The Author(s), under exclusive licence to the International Pediatric Research Foundation, Inc 2023. | Chen, Szu-Han;

| ○ | ○ | Article | Estimation of concrete compressive strength from non-destructive tests using a customized neural network and genetic algorithm | This paper introduces a novel approach for deriving an equation aimed at predicting concrete compressive strength, leveraging two non-destructive test results: ultrasonic pulse velocity and rebound hammer value. Traditional regression methods often fail to capture the complex non-linear relationships crucial for accurate concrete CS estimation, leading to limited effectiveness. In contrast, while machine learning models excel at mapping these non-linear relationships from non-destructive test results, their intricate internal mechanisms can be opaque, posing challenges for practical application and comprehension by engineers. This study aims to bridge these gaps by developing an estimation equation derived from the decoded weights of a neural network specifically designed to capture the intricate nonlinear mapping relationship. Initially, the equation is intricate and lengthy, comprising multiple terms. To streamline and refine it, a genetic algorithm is employed, focusing solely on the most pivotal terms. Consequently, the refined prediction equation demonstrates superior estimation performance with an RMSE of 3.40 MPa, an MAE of 2.70 MPa, an R2 2 of 0.92, and an R of 0.97 compared to several existing formulations. Furthermore, a comparative analysis is undertaken to assess the impact of the degree of equation simplification on its predictive accuracy. The findings offer insights into the pivotal roles of exponential function terms in enhancing prediction performance, as well as elucidating trigonometric function terms contribute the model's complex non-linear mapping capability. | Park, Jun Su; Park, Sinwon; Oh, Byung Kwan; Hong, Taehoon; Lee, Dong-Eun; Park, Hyo Seon | Yonsei Univ, Dept Architecture & Architectural Engn, Seoul 03722, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Engn Environm & Energy, Daegu, South Korea | ; Park, Jun Su/HTR-3899-2023 | 57161433100; 58790763200; 56134318500; 57969349700; 56605563300; 55669886900 | hspark@yonsei.ac.kr; | APPLIED SOFT COMPUTING | APPL SOFT COMPUT | 1568-4946 | 1872-9681 | 164 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS | 2024 | 6.6 | 13.4 | 2.15 | 2025-05-07 | 8 | 7 | Concrete compressive strength; Non-destructive test; Customized neural network; Genetic algorithm | ULTRASONIC PULSE VELOCITY; IN-SITU STRENGTH; PREDICTION; CONSTRUCTION | Concrete compressive strength; Customized neural network; Genetic algorithm; Non-destructive test | Bridge decks; Complex networks; Compressive strength; Concretes; Exponential functions; Forecasting; Mapping; Nondestructive examination; Nonlinear equations; Regression analysis; Ultrasonic testing; Concrete compressive strength; Customized neural network; Machine learning models; Neural networks and genetic algorithms; Neural-networks; Non-linear relationships; Nondestructive tests; Rebound hammers; Regression method; Ultrasonic pulse velocity; Genetic algorithms | English | 2024 | 2024-10 | 10.1016/j.asoc.2024.111941 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | High-density cluster core-based k-means clustering with an unknown number of clusters | The k -means algorithm, known for its simplicity and adaptability, faces challenges related to manual cluster number selection and sensitivity to initial centroid placement. This paper introduces an innovative framework aimed at overcoming these challenges. By proposing a data -driven cluster number estimation method and a robust initialization strategy based on high -density cluster cores, our approach revolutionizes k -means, unlocking its full unsupervised potential and ensuring superior performance, even in scenarios involving overlapping clusters. The method employs a novel density -based technique to accurately identify cluster cores, resulting in substantial improvements over existing methods. Rigorous experimentation on synthetic and realworld datasets demonstrates an average performance enhancement of 15% in terms of the Adjusted Rand Index for datasets with overlapping clusters, surpassing the capabilities of state-of-the-art density -based clustering methods and traditional k -means. Moreover, our method autonomously determines the optimal number of clusters, facilitating true unsupervised learning and eliminating the impact of initial centroid placement on clustering outcomes. This leads to stable and consistent results, addressing key limitations of the conventional k -means algorithm. The practical applicability of our approach is exemplified in image segmentation tasks, showcasing its versatility and reliability in real -world scenarios. | Kumar, Abhimanyu; Kumar, Abhishek; Mallipeddi, Rammohan; Lee, Dong-Gyu | Kyungpook Natl Univ, Dept Artificial Intelligence, Daehak ro, Daegu 41566, South Korea | Kumar, Abhishek/ABA-5251-2021; Mallipeddi, Rammohan/AAL-5306-2020 | 57845674200; 57206266703; 25639919900; 57169003900 | abbhi.kummar@gmail.com;abhishek.ai@knu.ac.kr;mallipeddi@knu.ac.kr;dglee@knu.ac.kr; | APPLIED SOFT COMPUTING | APPL SOFT COMPUT | 1568-4946 | 1872-9681 | 155 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS | 2024 | 6.6 | 13.4 | 5.84 | 2025-05-07 | 17 | 22 | k-means; Data clustering; Unsupervised learning; Image segmentation | DATA SET; VALIDATION; REDUCTION | Data clustering; Image segmentation; k-means; Unsupervised learning | Cluster analysis; K-means clustering; Unsupervised learning; Cluster cores; Cluster numbers; Data clustering; High density clusters; Images segmentations; K-mean algorithms; K-means; K-means++ clustering; Number of clusters; Overlapping clusters; Image segmentation | English | 2024 | 2024-04 | 10.1016/j.asoc.2024.111419 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Learnable feature alignment with attention-based data augmentation for handling data issue in ancient documents | Recognizing ancient cursive handwritten characters presents unique challenges due to the diversity of writing styles and significant class imbalances, where some characters have disproportionately more samples than others. This imbalance leads to higher misclassification rates for minority classes compared to majority classes. To address these challenges, we propose a novel framework that integrates learnable channel and spatial attention modules to effectively align features between source and target domains for better representation. Our approach incorporates a learnable sequential feature alignment process that dynamically adjusts to the specific characteristics of the data, enhancing the transfer of knowledge across domains. Furthermore, we introduce an attention-based augmentation module to amplify the influence of tail classes. This module leverages class activation maps to identify and augment discriminative features, ensuring the model focuses on the most semantically rich regions, particularly for minority classes. Asa result, it aligns the weight norms of minority classes with those of majority classes, effectively mitigating the limitations posed by imbalanced class distributions. This approach effectively mitigates the constraints posed by imbalanced character distributions in ancient handwritten documents. The proposed method increases the accuracy for the CCR, Hanja, Nancho, and Kuzushiji datasets. | Jalali, Amin; Lee, Sangbeom; Lee, Minho | Kyungpook Natl Univ, KNU LG Elect Convergence Res Ctr, AI Inst Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Grad Sch Artificial Intelligence, Daegu 41566, South Korea; ALI Co Ltd, Daegu 41566, South Korea; Queens Univ, Dept Elect & Comp Engn, Ingenu Labs Res Inst, Kingston, ON, Canada | Jalali, Amin/AAH-6921-2019 | 57022190400; 59250688200; 57191730119 | max.jalali@gmail.com;mholee@gmail.com; | APPLIED SOFT COMPUTING | APPL SOFT COMPUT | 1568-4946 | 1872-9681 | 167 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS | 2024 | 6.6 | 13.4 | 0 | 2025-05-07 | 0 | 0 | Learnable feature alignment; Ancient character recognition; Imbalanced low data; Attentive data generator | RECOGNITION; NETWORK | Ancient character recognition; Attentive data generator; Imbalanced low data; Learnable feature alignment | Data accuracy; Spatio-temporal data; Ancient character recognition; Ancient documents; Attentive data generator; Class imbalance; Data augmentation; Feature alignment; Hand-written characters; Imbalanced low data; Learnable feature alignment; Writing style; Data assimilation | English | 2024 | 2024-12 | 10.1016/j.asoc.2024.112394 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Sustainable Starch-Extracted Amylose-Rich/Tannic Acid Adhesives with Robust Adhesion Properties on Wood Substrates | Presently, a wide range of commercial wood adhesives are formaldehyde-based and derived from petroleum resources, causing major environmental concerns. The urgent requirement to minimize the production of formaldehyde, which can have damaging consequences for living organisms, has necessitated the development of eco-friendly adhesives derived from biobased sources. This study presents a novel, eco-friendly wood adhesive using amylose (AM) extracted from biobased starch (ST). The isolation of starch yields two distinct components, AM and amylopectin (AP). The use of the isolated AM-rich component, in conjunction with tannic acid, a natural polyphenolic compound, results in the formation of a formaldehyde-free adhesive derived from natural products through simple blending, without the need for additional cross-linking agents. The adhesive forms as the AM-rich solution recrystallizes via hydrogen bonding, creating a double helix structure and resulting in a hydrogel with a three-dimensional network. TA infiltrates the AM matrix, reducing matrix crystallinity by lowering interchain hydrogen bonding, which enhances adhesion by decreasing viscosity and increasing penetration and spreadability into wood pores. In addition, the AM-rich/TA adhesive formed a robust hydrogen bond with the wood substrate by the polyphenol present in TA, showing higher bonding strength and adhesion strength than the wood itself, supporting a weight of up to 23 kg. The phenolic moieties of TA exhibit good antibacterial and antimildew properties. Therefore, the multifunctional AM-rich/TA hydrogel is a sustainable and environmentally friendly adhesive with superior adhesion properties. This sustainable material offers a practical substitute for petroleum-derived adhesives and addresses the environmental concerns associated with their use. | Jeong, Yu Jin; Chathuranga, Kiramage; Lee, Jong-Soo; Kim, Min Hee; Park, Won Ho | Chungnam Natl Univ, Dept Organ Mat Engn, Daejeon 34134, South Korea; Chungnam Natl Univ, Coll Vet Med, Dept Vet Microbiol, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dept Text Engn, Sangju 37223, South Korea | ; Kim, Minhee/M-1628-2019; Chathuranga, Kiramage/AAS-6339-2020 | 57741446500; 57194522108; 56042332000; 57188948163; 57211114215 | mhkim88@knu.ac.kr;parkwh@cnu.ac.kr; | ACS SUSTAINABLE CHEMISTRY & ENGINEERING | ACS SUSTAIN CHEM ENG | 2168-0485 | 12 | 38 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2024 | 7.3 | 13.4 | 0.51 | 2025-05-07 | 4 | 4 | Starch; Amylose; Tannic acid; Hydrogenbonding; Wood adhesive; Eco-friendly | PHYSICOCHEMICAL PROPERTIES; POLY(VINYL ALCOHOL); TANNIC-ACID; PERFORMANCE; UREA; UV; MONTMORILLONITE; ANTIOXIDANT; POLYPHENOLS; GLYOXAL | Amylose; Eco-friendly; Hydrogen bonding; Starch; Tannic acid; Wood adhesive | Amylopectins; Bond strength (materials); Crosslinking; Tannins; Wood products; Adhesion properties; Amylose; Bio-based; Eco-friendly; Environmental concerns; Living organisms; Petroleum resources; Tannic acid; Wood adhesives; Wood substrates; Hydrogen bonds | English | 2024 | 2024-09-13 | 10.1021/acssuschemeng.4c05829 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Syngas Production via CO2-Mediated Melamine Pyrolysis | Melamine is an extensively used fire retardant in various commercial products. Along with its applications, awareness about its toxicity also increases and the accelerated rate of waste generation has become a concern. This study proposes a systematic approach for the conversion of melamine into syngas. For enhanced sustainability of this process, CO2 was used as the reactive medium during pyrolysis. Before pyrolysis, melamine was examined by using thermogravimetric analysis and pyrolysis-gas chromatography. Subsequent melamine pyrolysis yielded only ammonia and condensed pyrolysates. A double-stage pyrolysis setup was used to optimize the thermal cracking of melamine. Under CO2 conditions, CO was generated although melamine lacks an inherent oxygen source. The CO evolution under the CO2 condition is attributed to the homogeneous interaction between CO2 and volatile pyrolysates. However, the slow kinetics of this homogeneous reaction hinders its complete activation. To expedite the homogeneous reaction, a Ni catalyst was introduced. The concentration of CO from catalytic pyrolysis under the CO2 condition enhanced 109 times (35 mol %) compared to double-stage pyrolysis setup. Furthermore, melamine completely transformed into gaseous pyrolysates after catalytic pyrolysis under CO2 conditions. All experimental observations highlighted that melamine pyrolysis under CO2 and a Ni catalyst could be a useful energy and chemical recovery approach. | Cho, Seong-Heon; Park, Jonghyun; Jung, Sungyup; Tsang, Yiu Fai; Lee, Doyeon; Kwon, Eilhann E. | Hanyang Univ, Dept Earth Resources & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Educ Univ Hong Kong, Dept Sci & Environm Studies, Hong Kong 999077, Peoples R China; Educ Univ Hong Kong, State Key Lab Marine Pollut, Hong Kong 999077, Peoples R China; Hanbat Natl Univ, Dept Civil & Environm Engn, Daejeon 34158, South Korea | Jung, Sungyup/ABE-1493-2021; Kwon, Eilhann/AGY-3339-2022; Tsang, Yiu/AAJ-2524-2020 | 56583023200; 58544742000; 55073290800; 22954605700; 55881252900; 9240622100 | ek2148@hanyang.ac.kr; | ACS SUSTAINABLE CHEMISTRY & ENGINEERING | ACS SUSTAIN CHEM ENG | 2168-0485 | 12 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, CHEMICAL;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2024 | 7.3 | 13.4 | 2.82 | 2025-05-07 | 12 | 11 | melamine; waste-to-energy; circular economy; CO2 utilization; thermal treatment; syngas | THERMAL-DEGRADATION; UREA-FORMALDEHYDE; WASTE; PHOSPHATE; CATALYST; RESIN; OIL; CO2 | circular economy; CO<sub>2</sub> utilization; melamine; syngas; thermal treatment; waste-to-energy | Ammonia; Catalysts; Gas chromatography; Nickel; Pyrolysis; Reaction kinetics; Synthesis gas; Thermogravimetric analysis; Waste treatment; Catalytic pyrolysis; Circular economy; CO2 utilization; Condition; Double stage; Homogeneous reaction; Ni catalysts; Pyrolysates; Syn gas; Waste to energy; Carbon dioxide | English | 2024 | 2024-01-29 | 10.1021/acssuschemeng.3c08359 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Health screening disparities in people living with HIV; A nationwide organized screening setting | Background: We identified the uptake of people living with HIV (PLWH) using health-screening services and compared the screening rate with the general population, to identify factors associated with the use of screening services by PLWH. Methods: This population-based study used data from the Korean National Health Insurance, a single mandatory health insurance system covering all residents. The uptake rates for screening for general health, gastric cancer, and colorectal cancer, which were provided by a national health screening program with free of charge or minimal cost in Korea from 2010-2020. Factors associated with general health, gastric cancer, and colorectal cancer screening were also explored. Results: Screening uptake rates for general health, gastric cancer, and colorectal cancer in PLWH increased from 2010-2019 but decreased in 2020. The standardized screening ratio showed lower screening rates for general health, gastric cancer, and colorectal cancer in PLWH with 0.80 (95 % confidence interval (CI) = 0.77-0.83), 0.64 (95 % CI = 0.61-0.67), and 0.67 (95 % CI = 0.64-0.71) in 2019. Increased age, Charlson Comorbidity Index, and years since HIV diagnosis were associated with increased screening uptake in PLWH. Otherwise, PLWH recipients of medical aid programs received less for each screening compared to PLWH who paid insurance premiums higher than 50 %. An increased medication possession ratio of highly active antiretroviral therapy was associated with decreased general health and gastric cancer screening uptake but increased colorectal cancer screening uptake. Conclusions: Significant disparities in health-screening uptake were observed in PLWH compared to the general population in a nationwide organized screening setting without cost barriers.
