| ○ | ○ | Article | Development of a 7-DOF Biodynamic Model for a Seated Human and a Hybrid Optimization Method for Estimating Human-Seat Interaction Parameters | Existing biodynamic models adopt apparent mass and seat-to-head transmissibility to predict the response of seated humans to whole-body vibration, limiting their ability to capture the actual response of distinct body segments in different excitation conditions. This study systematically develops a 7-DOF seated human model, a vibration experiment, and a novel hybrid optimization to estimate unknown mechanical parameters and predict the response of different human body segments to vertical vibrations. Experimental results showed that the upper trunk and head were most susceptible to transmitted vibrations. Combining the 7-DOF model and HOM resulted in accelerated optimization, improved numerical stability, and significant minimization of the objective function value compared to conventional algorithms. Notably, the estimated parameters, particularly stiffness, remained consistent regardless of increasing excitation magnitude or change in the body segment data used. Additionally, the model captured the non-linearity in human biodynamics through stiffness softening. These findings are applicable in seating systems optimization for comfort and safety. | Alabi, Abeeb Opeyemi; Song, Byoung-Gyu; Bae, Jong-Jin; Kang, Namcheol | Kyungpook Natl Univ, Dept Mech Engn, Daegu 41566, South Korea; Korea Aerosp Res Inst, KSLV II R&D Directorate, Daejeon 34133, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | 58629744100; 57211027939; 55631622800; 24830970900 | alabiabeeb14@gmail.com;sbg045@knu.ac.kr;jjbae@kari.re.kr;nckang@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.13 | 2025-06-25 | 1 | 1 | seated human model; hybrid optimization methodology; vertical vibrations; parameter estimation; whole-body vibration | WHOLE-BODY VIBRATION; APPARENT MASS; BIOMECHANICAL MODEL; VERTICAL VIBRATION; TRANSMISSIBILITY; RESPONSES; EXPOSURE | hybrid optimization methodology; parameter estimation; seated human model; vertical vibrations; whole-body vibration | English | 2023 | 2023-09 | 10.3390/app131810065 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Digital Twin-Driven Framework for TBM Performance Prediction, Visualization, and Monitoring through Machine Learning | The rapid development in underground infrastructure is encouraging faster and more modern ways, such as TBM tunneling, to meet the needs of the world. However, tunneling activities generate complex and heterogeneous data, which makes it difficult to visualize the performance of a project. Advancements in information technology, such as digital twins and machine learning, provide platforms for digital demonstration, visualization, and system performance monitoring of such data. Therefore, this study proposes a digital twin-driven framework for TBM performance prediction through machine learning, visualization, and monitoring. This novel approach integrates machine learning and real-time performance data to predict, visualize, and monitor the status of the tunnel construction progress. A digital twin virtual model of TBM was constructed based on TBM design parameters, the input parameter, boring energy, RPM, torque, thrust force, speed, gripper pressure, total revolution, and Q-value provided to SVR and ANN models to predict the TBM AR and PR, and TBM daily progress was visualized continuously. The predictive performance indices R2 (0.97) and RMSE (0.011) were estimated for AR prediction, showing the accuracy of the proposed model. To demonstrate the proposed framework, this study shows the its effectiveness. By implementing this framework, stakeholders can minimize the risk associated with the cost and schedule of a tunneling project by simultaneously visualizing and monitoring the performance of TBMs through digital twin and machine learning algorithms. | Latif, Kamran; Sharafat, Abubakar; Seo, Jongwon | Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea | Sharafat, Abubakar/ITW-2048-2023 | 57221094832; 57204630290; 7401783784 | kamran5latif@gmail.com;abubakarsharafat89@gmail.com;jseo@hanyang.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 4.67 | 2025-06-25 | 29 | 36 | tunnel boring machine (TBM); TBM performance; digital twin (DT); machine learning (ML); visualization; monitoring | TUNNEL BORING MACHINE; PENETRATION RATE; OPTIMIZATION TECHNIQUES; MODEL; ANN | digital twin (DT); machine learning (ML); monitoring; TBM performance; tunnel boring machine (TBM); visualization | English | 2023 | 2023-10 | 10.3390/app132011435 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of a Silk Sericin and Methylsulfonylmethane (MSM) Blends on Inflammatory Response and Wound Healing | The natural product silk sericin has excellent biological properties, such as biocompatibility, biodegradability, and antioxidant activity, and it also facilitates cell proliferation, collagen type 1 production, and wound healing. Methylsulfonylmethane (MSM) is a natural organic sulfur compound known to relieve pain and inflammation. In this study, we formulated sericin and MSM blends in various ratios, and investigated their effects on the inflammatory response and subsequent healing of a wound in vitro using macrophages and fibroblasts. The experimental findings, derived from cell viability analyses and nuclear factor kappa B (NF kappa B)/cyclooxygenase-2 (COX-2)/inducible nitric oxide synthase (iNOS) pathway assays, demonstrated that the anti-inflammatory activity of MSM was more effective when it was blended with sericin. In contrast, MSM alone did not enhance wound healing but rather delayed it at higher concentrations. We confirmed that the blend of sericin and MSM exhibited a synergistic effect on suppressing inflammatory responses and promoting subsequent wound healing when the two materials were optimally blended. | Jeong, Hyun-Lyung; Kang, Eun-Bin; Yun, Seung-Geun; Park, Dan-bi; Lim, Jeong-Ok; Suh, Jang-Soo | Innoregen Inc, Dongnae ro 88, Daegu 401601, South Korea; Kyungpook Natl Univ, Joint Inst Regenerat Med, Dongdeok ro 130, Daegu 41944, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Biomed Res Inst, Sch Med, Dongdeok ro 135, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Dongdeok ro 130, Daegu 41944, South Korea | 58044178900; 58044435600; 58044690800; 57235629000; 7403454245; 57201729629 | jolim@knu.ac.kr;suhjs@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 1.3 | 2025-06-25 | 10 | 10 | sericin; methylsulfonylmethane; inflammatory response; wound healing | NF-KAPPA-B; DOWN-REGULATION; PROTEIN; GROWTH; FIBROBLAST; ATTACHMENT | inflammatory response; methylsulfonylmethane; sericin; wound healing | English | 2023 | 2023-01 | 10.3390/app13010288 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Enhancing Lane-Tracking Performance in Challenging Driving Environments through Parameter Optimization and a Restriction System | The autonomous driving market has experienced rapid growth in recent times. From systems that assist drivers in keeping within their lanes to systems that recognize obstacles using sensors and then handle those obstacles, there are various types of systems in autonomous driving. The sensors used in autonomous driving systems include infrared detection devices, lidar, ultrasonic sensors, and cameras. Among these sensors, cameras are widely used. This paper proposes a method for stable lane detection from images captured by camera sensors in diverse environments. First, the system utilizes a bilateral filter and multiscale retinex (MSR) with experimentally optimized set parameters to suppress image noise while increasing contrast. Subsequently, the Canny edge detector is employed to detect the edges of the lane candidates, followed by utilizing the Hough transform to make straight lines from the land candidate images. Then, using a proposed restriction system, only the two lines that the current vehicle is actively driving within are detected from the candidate lines. Furthermore, the lane position information from the previous frame is combined with the lane information from the current frame to correct the current lane position. The Kalman filter is then used to predict the lane position in the next frame. The proposed lane-detection method was evaluated in various scenarios, including rainy conditions, low-light nighttime environments with minimal street lighting, scenarios with interfering guidelines within the lane area, and scenarios with significant noise caused by water droplets on the camera. Both qualitative and quantitative experimental results demonstrate that the lane-detection method presented in this paper effectively suppresses noise and accurately detects the two active lanes during driving. | Lee, Seung-Hwan; Kwon, Hyuk-Ju; Lee, Sung-Hak | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Deahak Ro, Daegu 41566, South Korea | ; Lee, SeungHwan/LUY-2745-2024 | 58149054300; 55169908300; 7601395661 | hyo98120@knu.ac.kr;olin1223@knu.ac.kr;shak2@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 16 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.52 | 2025-06-25 | 3 | 4 | lane detection; multiscale retinex (MSR); restriction system; lane tracking | lane detection; lane tracking; multiscale retinex (MSR); restriction system | English | 2023 | 2023-08 | 10.3390/app13169313 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Ethyl Formate as a New Sanitary Treatment for Disinfesting the Hitchhiking Insect Pest Halyomorpha halys on Imported Nonfood Agricultural Machinery | With an increase in the international trade of agricultural and non-agricultural products, there is an increase in the possibility of introducing hitchhiking insect pests such as Halyomorpha halys, which has been detected on imported vehicles and agricultural machinery. Although methyl bromide (MB) is provisionally used to control invasive pests, it is classified as a restricted chemical owing to its potential to deplete the ozone layer and pose health risks to humans in cases of inadequate ventilation, as well as concerns regarding consumer safety. Therefore, this study investigated ethyl formate's (EF's) efficacy against H. halys and its efficacy and sorption, as an alternative to MB, on main electronic components, including alternators, ignition coils, and motors. Fumigation with 35 and 70 g/m(3) EF for 4 h at 15 degrees C had no damage on the main electronic components as evaluated using various operation tests. In a commercial trial, H. halys infestation was effectively controlled with 35 g/m(3) EF fumigated for 4 h at 23 degrees C using a 30 m(3) polyvinyl chloride tarpaulin fumigation chamber. After ventilation, the EF concentration decreased below the safety level within 10 min and reached the zero level within 40 min for worker safety. This novel sanitary treatment using EF fumigation on imported agricultural machinery could be an effective method without causing mechanical damage. | Kim, Kyeongnam; Kim, Dongbin; Lee, Byung-Ho; Roh, Gwang Hyun; Kim, Kyung Won; Jeon, Hwan-Young; Lee, Sung-Eun | Kyungpook Natl Univ, Inst Qual & Safety Evaluat Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Gyeongsang Natl Univ, Inst Agr & Life Sci, Dept Plant Med, Jinju 52828, South Korea; Anim & Plant Quarantine Agcy, Gimcheon 39660, South Korea; Busan Inst Sci & Technol, Div Automobile, Busan 46639, South Korea | ; Kim, Kyeongnam/KSM-2719-2024 | 57191364349; 57209617411; 57202841615; 57200086079; 57255195400; 59066054800; 55890041600 | kn1188@knu.ac.kr;dongbinkim@knu.ac.kr;byungholee@hotmail.com;ghroh@gnu.ac.kr;nkwkim@korea.kr;jhy1970@bist.ac.kr;selpest@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.13 | 2025-06-25 | 1 | 1 | fumigation; international trade; sanitary disinfestation; reactivity test; imported agricultural machinery; brown marmorated stink bug | METHYL-BROMIDE; HEMIPTERA-PENTATOMIDAE; FUMIGATION; IMPACT | brown marmorated stink bug; fumigation; imported agricultural machinery; international trade; reactivity test; sanitary disinfestation | English | 2023 | 2023-11 | 10.3390/app132111764 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Evaluating the Strength and Durability of Eco-Friendly Stabilized Soil Bricks Incorporating Wood Chips | The production of commercially used cement-based bricks has significant environmental implications, necessitating the development of robust, environmentally friendly alternatives. This study assesses the strength and durability of soil bricks by utilizing an eco-friendly stabilizer, which includes lime and natural-fiber-derived staple fibers. Soil bricks, each sized 50 mm x 100 mm and featuring varying proportions of stabilizer and wood chips, were subjected to unconfined compression and bending strength tests, permeability assessments, steel ball/golf ball (SB/GB) evaluations, and wetting-drying tests. The results demonstrated that higher stabilizer ratios and lower wood chip ratios led to enhanced unconfined compressive strength. Additionally, repeated wetting-drying cycles reduced the strength by up to 63%, while the relative dynamic modulus of elasticity decreased by as much as 45% with increasing wetting-drying cycles. Notably, the eco-friendly stabilizer significantly improved soil shear strength, ultimately enhancing the durability of the soil bricks. | Youn, Ilro; Bang, Seongtaek; Jeong, Yoseok; Oh, Sewook | Kyungpook Natl Univ, Dept Construct & Disaster Prevent Engn, Sangju 37224, Gyeongbuk, South Korea | ysjeong@knu.ac.kr;osw@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0 | eco-friendly stabilizer; wood chips; unconfined compressive strength; wetting-drying cycles; relative dynamic modulus of elasticity; SB/GB factor | English | 2023 | 2023-10 | 10.3390/app131910929 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Experimental Study of Morphological Analyzers for Topic Categorization in News Articles | Natural language processing refers to the ability of computers to understand text and spoken words similar to humans. Recently, various machine learning techniques have been used to encode a large amount of text and decode feature vectors of text successfully. However, understanding low-resource languages is in the early stages of research. In particular, Korean, which is an agglutinative language, needs sophisticated preprocessing steps, such as morphological analysis. Since morphological analysis in preprocessing significantly influences classification results, ideal and optimized morphological analyzers must be used. This study explored five state-of-the-art morphological analyzers for Korean news articles and categorized their topics into seven classes using term frequency-inverse document frequency and light gradient boosting machine frameworks. It was found that a morphological analyzer based on unsupervised learning achieved a computation time of 6 s in 500,899 tokens, which is 72 times faster than the slowest analyzer (432 s). In addition, a morphological analyzer using dynamic programming achieved a topic categorization accuracy of 82.5%, which is 9.4% higher than achieve when using the hidden Markov model (73.1%) and 13.4% higher compared to the baseline (69.1%) without any morphological analyzer in news articles. This study can provide insight into how each morphological analyzer extracts morphemes in sentences and affects categorizing topics in news articles. | Ahn, Sangtae | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | Ahn, Sangtae/AFQ-7342-2022 | 55468016100 | stahn@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.26 | 2025-06-25 | 2 | 2 | natural language processing; morphological analyzer; topic categorization; news article | morphological analyzer; natural language processing; news article; topic categorization | English | 2023 | 2023-10 | 10.3390/app131910572 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Experiments and Design of an Anti-Disaster Support System for Apple Orchards | A number of apple trees have collapsed in South Korea due to strong winds caused by typhoons. In fact, apple trees are protected by various types of support systems. However, despite this, they have still been damaged. The reason why the trees collapsed is that the installation of a support system is based not on scientific facts but on empirical facts. The purpose of this study was to evaluate the structural safety of the anti-disaster support system of apple trees. Equivalent static tests of the support systems, i.e., fences and matrix supports, were carried out. The result of the equivalent static tests indicated that the bearing capacity of the foundation is considered an important factor for the performance of the fence support, and the elements played a major role in the case of the matrix support due to the connection of the strut wire and the mat wire. Based on this test result, design criteria and standard specifications of the apple tree support system in response to local wind speed are proposed. | Lee, Hee-Du; Lee, Swoo-Heon; Shin, Kyung-Jae; Lee, Jun-Seop | Kyungpook Natl Univ, Reg Ctr Land Infrastruct & Transport Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Convergence & Fus Syst Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea | ; Lee, Swoo-Heon/AGO-7501-2022 | 53865180300; 34869937600; 14039501000; 57221623386 | lhdza@knu.ac.kr;finksnow@knu.ac.kr;shin@knu.ac.kr;kore6987@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0 | 2025-06-25 | 0 | 0 | anti-disaster; performance design; support system; equivalent static test; apple orchards | anti-disaster; apple orchards; equivalent static test; performance design; support system | English | 2023 | 2023-09 | 10.3390/app131810033 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Feature Map Analysis of Neural Networks for the Application of Vacant Parking Slot Detection | Vacant parking slot detection using image classification has been studied for a long time. Currently, deep neural networks are widely used in this research field, and experts have concentrated on improving their performance. As a result, most experts are not concerned about the features extracted from the images. Thus, no one knows the crucial features of how neural networks determine whether a particular parking slot is full. This study divides the structures of neural networks into feature extraction and classification parts to address these issues. The output of the feature extraction parts is visualized through normalization and grayscale imaging. The visualized feature maps are analyzed to match the feature characteristics and classification results. The results show that a specific region of feature maps is activated if the parking slot is full. In addition, it is verified that different networks whose classification parts are identical extract similar features from parking slot images. This study demonstrates that feature map analyses help us find hidden characteristics of features and understand how neural networks operate. Our findings show a possibility that handcrafted algorithms using the features found by machine learning algorithms can replace neural network-based classification parts. | Hwang, Jung-Ha; Cho, Byungwoo; Choi, Doo-Hyun | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Hankyong Natl Univ, Sch ICT Robot & Mech Engn, Anseong 17579, South Korea; Korea Inst Med Microrobot KIMIRo, Gwangju 61011, South Korea | 58627137700; 58627675200; 7401642881 | comand4812@gmail.com;bwcho@kimiro.re.kr;dhc@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.39 | 2025-06-25 | 2 | 3 | vacant parking slot detection; image classification; deep neural networks; feature extraction; feature map visualization | deep neural networks; feature extraction; feature map visualization; image classification; vacant parking slot detection | English | 2023 | 2023-09 | 10.3390/app131810342 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Impact of Secure Container Runtimes on File I/O Performance in Edge Computing | Containers enable high performance and easy deployment due to their lightweight architecture, thus facilitating resource utilization in edge computing nodes. Secure container runtimes have attracted significant attention because of the necessity for overcoming the security vulnerabilities of containers. As the runtimes adopt an additional layer such as virtual machines and user-space kernels to enforce isolation, the container performance can be degraded. Even though previous studies presented experimental results on performance evaluations of secure container runtimes, they lack a detailed analysis of the root causes that affect the performance of the runtimes. This paper explores the architecture of three secure container runtimes in detail: Kata containers, gVisor, and Firecracker. We focus on file I/O, which is one of the key aspects of container performance. In addition, we present the results of the user- and kernel-level profiling and reveal the major factors that impact the file I/O performance of the runtimes. As a result, we observe three key findings: (1) Firecracker shows the highest file I/O performance as it allows for utilizing the page cache inside VMs, and (2) Kata containers offer the lowest file I/O performance by consuming the largest amount of CPU resources. Also, we observe that gVisor scales well as the block size increases because the file I/O requests are mainly handled by the host OS similar to native applications. | Lee, Kyungwoon; Kim, Jeongsu; Kwon, Ik-Hyeon; Park, Hyunchan; Hong, Cheol-Ho | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Agcy Def Dev, Daejeon 34186, South Korea; Chung Ang Univ, Sch Elect & Elect Engn, Seoul 06974, South Korea; Jeonbuk Natl Univ, Dept Comp Sci & Artificial Intelligence, CAIIT, Jeonju 54896, South Korea; Chung Ang Univ, Dept Intelligent Semicond Engn, Seoul 06974, South Korea | Lee, Kyungwoon/AGE-8826-2022 | 57190025432; 59075072200; 59075072300; 23478123400; 35179802400 | kwlee87@knu.ac.kr;jeongsukim0122@gmail.com;inzulmi@cau.ac.kr;hyunchan.park@jbnu.ac.kr;cheolhohong@cau.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 24 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.13 | 2025-06-25 | 1 | 1 | container runtimes; security; I/O performance; kernel-level profiling | VIRTUALIZATION | container runtimes; I/O performance; kernel-level profiling; security | English | 2023 | 2023-12 | 10.3390/app132413329 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Indium Zinc Tin Oxide Bottom Electrode-Based Flexible Indoor Organic Photovoltaics with Remarkably High Mechanical Stability | The demand for flexible indoor organic photovoltaic cells (OPVs) is growing dramatically due to their simple and practical use as a powering aid for various electronic gadgets connected to the Internet of Things. Due to the brittleness of inorganic material-based transparent bottom electrodes and their incompatibility with flexible organic substrates, it is extremely difficult to limit the influence of mechanical stress on the stability of flexible OPV. In this regard, choosing a mechanically stable and highly conductive transparent conducting oxide (TCO) is crucial. Therefore, flexible OPVs are fabricated onto a flexible (polyimide) substrate coated with mechanically stable TCO indium zinc tin oxide (IZTO). Sheet resistance measurements and observations of scanning electron microscope images of IZTO film after 100 000 bending repetitions (bending radius: 5 mm) confirm the ultrahigh mechanical stability of the TCO. The sheet resistance of flexible IZTO electrode layers is increased by 9%, from 17.42 to 19.12 & omega; sq(-1).

| ○ | ○ | Article | Localization of Cracks in Concrete Structures Lacking Reference Objects and Feature Points Using an Unmanned Aerial Vehicle | Information on the location of cracks in concrete structures is an important factor enabling appropriate maintenance or reinforcement measures to be taken. Most studies related to concrete cracks are limited to crack detection and identification, and studies related to crack location information are insufficient. The novelty of this study is to develop application technology related to crack localization by proposing a methodology that can estimate the location of concrete cracks even when reference objects or feature points are lacking using an unmanned aerial vehicle and image processing techniques. For the development and verification of the proposed method, aerial photography and image acquisition were performed using mounting a laser pointer model on an unmanned aerial vehicle. To build the analysis data, image distortion correction and feature point extraction were performed using the homography matrix and scale-invariant feature transform algorithm. Spatial information was established using the point cloud technique and image stitching technique, and crack localization was estimated using generating crack expression data via layer merging. The proposed method was validated using comparison with field-measured data. In the future, the proposed methodology can be utilized for supplementing and improving the conventional methods for visual inspection of infrastructures and facilities. | Baek, Seung-Chan; Oh, Jintak; Woo, Hyun-Jung; Kim, In-Ho; Jang, Sejun | Kyungil Univ, Dept Architecture, Gyongsan 38428, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Kunsan Natl Univ, Dept Civil Engn, Gunsan 54150, South Korea; Kunsan Natl Univ, Dept Architecture & Bldg Engn, Gunsan 54150, South Korea | 56909374400; 55977660300; 57219244497; 58576577100; 57200517339 | baeksc@kiu.ac.kr;jintak5@kiu.kr;woobi9107@knu.ac.kr;inho.kim@kunsan.ac.kr;jang@kunsan.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 17 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.52 | 2025-06-25 | 2 | 4 | unmanned aerial vehicle; concrete crack; image stitching; localization; laser pointer | concrete crack; image stitching; laser pointer; localization; unmanned aerial vehicle | English | 2023 | 2023-09 | 10.3390/app13179918 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Luteolin Protects Against Obese Sarcopenia in Mice with High-Fat Diet-Induced Obesity by Ameliorating Inflammation and Protein Degradation in Muscles | ScopeAlthough sarcopenia is mainly caused by aging, sarcopenia due to obesity has become an emerging issue given the increase in obesity among people of various ages. There are studies on obesity or sarcopenia, our understanding of obesity-mediated sarcopenia is insufficient. Luteolin (LU) has exhibited antiobesity effects, but no studies have investigated the LU effects on antisarcopenia. This study therefore investigated the effects of LU on obese sarcopenia in mice with high-fat diet (HFD)-induced obesity. Methods and resultsTo evaluate its inhibitory efficacy against obese sarcopenia, 5-week-old mice are fed an HFD supplemented with LU for 20 weeks. LU exerts suppressive effects on obesity, inflammation, and protein degradation in the HFD-fed obese mice. It also inhibits lipid infiltration into the muscle and decreases p38 activity and the mRNA expression of inflammatory factors, including TNF-alpha, Tlr2, Tlr4, MCP1, and MMP2, in the muscle. The suppression of muscle inflammation by LU leads to the inhibition of myostatin, FoxO, atrogin, and MuRF expression. These effects of LU affect inhibition of protein degradation and improvement of muscle function. ConclusionHere, it demonstrates that LU's antiobesity and antiinflammatory functionality affect inhibition of muscle protein degradation, and consequently, these interactions by LU exerts a protective effect against obese sarcopenia. | Kim, Ji-Won; Shin, Su-Kyung; Kwon, Eun-Young | Kyungpook Natl Univ, Dept Food Sci & Nutr, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Ctr Food & Nutr Genom Res, 80 Daehak Ro, Daegu 41566, South Korea | 57211318231; 23988149900; 15765422500 | eykwon@knu.ac.kr; | MOLECULAR NUTRITION & FOOD RESEARCH | MOL NUTR FOOD RES | 1613-4125 | 1613-4133 | 67 | 6 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2023 | 4.5 | 24.0 | 3.72 | 2025-06-25 | 23 | 27 | Inflammation; luteolin; obese sarcopenia; protein degradation; skeletal muscle | SKELETAL-MUSCLE; ADIPOSE-TISSUE; MITOCHONDRIAL BIOGENESIS; CROSS-TALK; RESISTANCE; ADIPONECTIN; MYOGENESIS; INTERPLAY; LEPTIN; SPARC | Inflammation; luteolin; obese sarcopenia; protein degradation; skeletal muscle | Animals; Diet, High-Fat; Inflammation; Insulin Resistance; Luteolin; Mice; Mice, Inbred C57BL; Mice, Obese; Muscle, Skeletal; Obesity; Proteolysis; Sarcopenia; luteolin; adverse event; animal; C57BL mouse; inflammation; insulin resistance; lipid diet; metabolism; mouse; mouse mutant; obesity; protein degradation; sarcopenia; skeletal muscle | English | 2023 | 2023-03 | 10.1002/mnfr.202200729 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | MIMO Over-the-Air Computation for Distributed Estimation | MIMO over-the-air computation (MIMO-AirComp) is a recently proposed technique that leverages the superposition property of the multiple access channel to compute the target multifunction of various applications. This article presents how the MIMO-AirComp principle can be applied to the state estimation problem using distributed sensing data. The representative target function is explicitly formulated as a nomographic function matched to the structure of the multiple access channel with the proper processing function. The proposed framework efficiently computes the target multifunction by coordinating local preprocessing at each node, aggregation through the wireless channel, and postprocessing at the fusion center. We analyze and demonstrate that the proposed approach significantly improves the computation throughput for the distributed estimation application. Specifically, the proposed MIMO-AirComp framework outperforms the conventional separated communication and computation approach when the network system relies on noisy measurements obtained by the densely deployed sensors. | Park, Pangun; Shin, Hyejeon; Di Marco, Piergiuseppe | Chungnam Natl Univ, Dept Radio & Informat Commun Engn, Daejeon 34134, South Korea; Kyungpook Natl Univ, Dent Clin Ctr, Daegu 41940, South Korea; Univ Aquila, Dept Informat Engn Comp Sci & Math, I-67100 Laquila, Italy | Di Marco, Piergiuseppe/JMR-4564-2023 | 35173287000; 57211492380; 35306717900 | pgpark@cnu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.39 | 2025-06-25 | 2 | 3 | over-the-air computation; MIMO; distributed estimation | DATA AGGREGATION; WIRELESS; CONVERGENCE; SYSTEMS; DESIGN; IOT | distributed estimation; MIMO; over-the-air computation | English | 2023 | 2023-02 | 10.3390/app13031593 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Monocular Depth Estimation Using Res-UNet with an Attention Model | Depth maps are single image metrics that carry the information of a scene in three-dimensional axes. Accurate depth maps can recreate the 3D structure of a scene, which helps in understanding the full geometry of the objects within the scene. Depth maps can be generated from a single image or multiple images. Single-image depth mapping is also known as monocular depth mapping. Depth maps are ill-posed problems that are complex and require extensive calibration. Therefore, recent methods use deep learning to develop depth maps. We propose a new method in monocular depth estimation to develop a high-quality depth map. Our approach is based on a convolutional neural network in which we used Res-UNet with a spatial attention model to develop depth maps. The addition of an attention mechanism increases the capability of feature extraction and enhances the boundaries features. It does not add any extra parameters to the network. With our proposed model, we demonstrate that a simple CNN model aided with an attention mechanism can create high-quality depth maps with a small iteration and training time. Our model performs very well compared to the existing state-of-the-art methods on the benchmark NYU-depth v2 dataset. Our model is flexible and can be applied to any depth mapping or multi-segmentation tasks. | Jan, Abdullah; Seo, Suyoung | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Dept Civil Engn, Daegu, South Korea | Seo, Suyoung/AAB-8465-2020 | 58298899200; 35198914000 | syseo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 13 | 10 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 2.5 | 24.0 | 0.39 | 2025-06-25 | 4 | 4 | monocular depth map; depth estimation; attention Res-UNet; CNN; scene reconstruction; three-dimensional; 3D; distance measurement; disparity | 3D; attention Res-UNet; CNN; depth estimation; disparity; distance measurement; monocular depth map; scene reconstruction; three-dimensional | English | 2023 | 2023-05-22 | 10.3390/app13106319 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
