| ○ | ○ | Article | Fully Digitalized Workflow of Flipper Fabrication: Different Three-Dimensional Printing Strategies and Characteristics | A flipper is an interim removable partial denture used for immediate esthetic restoration and space maintenance for a limited period before definitive treatment. Traditional methods for fabricating flippers are labor-intensive and manual. With the advent of technological advancement in dentistry, fully digitalized fabrication including computer designing and three-dimensional (3D) printing can be used. This study aimed to demonstrate the complete digital workflow for fabricating flippers and compare the features of different digital methods. In a partially edentulous patient, three flippers were fabricated using different digital protocols: individual printing (tooth and base parts) and combination, i.e., one-body printing and gingival layering and one-body printing and gingival coloring. Each flipper was tried into the oral cavity, and the adaptation of flippers was evaluated using the triple-scan technique. This study confirms that fully digital fabrication of a flipper is an effective method compared with traditional methods and shows various digital workflows available in 3D printing. Thus, an appropriate fabrication method must be selected for each situation. | Rana, Shilpa; Lee, Du-Hyeong | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | 59093226400; 35770948000 | ranashipu@gmail.com;deweylee@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 0 | 1 | flipper; fabrication; digital; 3D printing; triple scan | REMOVABLE PARTIAL DENTURE; PROSTHESIS | 3D printing; digital; fabrication; flipper; triple scan | English | 2024 | 2024-04 | 10.3390/app14072838 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Hydrostructural Phenomena in a Wastewater Screening Channel with an Ascendable Sub-Screen Using the Arbitrary Lagrangian-Eulerian Approach | Wastewater invariably accumulates soluble and insoluble waste and requires treatment at a wastewater treatment plant (WTP) to become reusable. The preliminary screening of insoluble waste occurs through a wastewater screening mechanism (WSM) before entering the WTP. The present study computationally investigates the impact of a WSM, comprising a main screen, sliding sub-screen, and rake, on channel flow distribution, deformation, and stresses. Various sub-screen configurations, fully and partially lowered, are examined. The fluid-structure interaction between sewage water and the WSM was solved using the arbitrary Lagrangian-Eulerian approach. Unlike similar studies in the past which have been conducted in 2D, the present study considers the 3D design and thus captures a greater complexity of the WSM assembly. The velocity distribution inside the channel, structural deformation, and von Mises stresses of WSM components were analyzed for a range of inlet velocities at different stages of the screening process. The results reveal that a fully lowered sub-screen with an inactive rake ensures a uniform flow through the WSM, while a partially lowered sub-screen induces persistent flow separation. Structural analysis reveals significant deformation in the upper mid-region of the sub-screen and fluctuating deformations in the rake, accompanied by elevated von Mises stresses. The study serves as a design guideline for manufacturing and operating a WSM, ensuring the prevention of unfavorable stress and deformation in the WSM and the WTP. | Akhtar, Shehnaz; Memon, Safi Ahmed; Chae, Hyeon-Bae; Choi, Du-Whan; Park, Cheol-Woo; Yu, Zhaosheng | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehakro, Daegu 41566, South Korea; I ENTEC Co Ltd, 18 Gil 33 Seongseogongdanbukro, Daegu 42712, South Korea | ; Akhtar, Shehnaz/IST-0523-2023 | 57202696797; 58757911600; 59075600000; 59076132900; 7408416474 | chwoopark@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.81 | 2025-04-16 | 2 | 2 | wastewater screening mechanism; flow separation; fluid-structure interaction; deformation; von Mises stress | OPTIMIZATION; NANOSCALE | deformation; flow separation; fluid–structure interaction; von Mises stress; wastewater screening mechanism | English | 2024 | 2024-01 | 10.3390/app14010076 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Intrinsic and Extrinsic Factors Associated with Hair Graying (Canities) and Therapeutic Potential of Plant Extracts and Phytochemicals | This review aims to gain insight into the major causes of hair graying (canities) and how plant-derived extracts and phytochemicals could alleviate this symptom. Research articles on human hair graying were searched and selected using the PubMed, Web of Science, and Google Scholar databases. We first examined the intrinsic and extrinsic factors associated with hair graying, such as the reduced capacity of melanin synthesis and transfer, exhaustion of melanocyte stem cells (MSCs) and melanocytes, genetics and epigenetics, race, gender, family history, aging, oxidative stress, stress hormones, systematic disorders, nutrition, smoking, alcohol consumption, lifestyle, medications, and environmental factors. We also examined various plants and phytochemicals that have shown a potential to interfere with the onset or progression of human hair graying at different levels from in vitro studies to clinical studies: the extract of Polygonum multiflorum and its major components, 2,3,5,4 '-tetrahydroxystilbene-2-O-beta-D-glucoside and emodin; the extract of Eriodictyon angustifolium and its major flavonoid compounds, hydroxygenkwanin, sterubin, and luteolin; the extracts of Adzuki beans (Vigna angularis), Fuzhuan brick tea (Camellia sinensis), and Gynostemma pentaphyllum; bixin, a carotenoid compound found in Bixa orellana; and rhynchophylline, an alkaloid compound found in certain Uncaria species. Experimental evidence supports the notion that certain plant extracts and phytochemicals could alleviate hair graying by enhancing MSC maintenance or melanocyte function, reducing oxidative stress due to physiological and environmental influences, and managing the secretion and action of stress hormones to an appropriate level. It is suggested that hair graying may be reversible through the following tactical approaches: selective targeting of the p38 mitogen-activated protein kinase (MAPK)-microphthalmia-associated transcription factor (MITF) axis, nuclear factor erythroid 2-related factor 2 (NRF2), or the norepinephrine-beta 2 adrenergic receptor (beta 2AR)-protein kinase A (PKA) signaling pathway. | Boo, Yong Chool | Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu 41405, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu 41944, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu 41944, South Korea | 6602899130 | ycboo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 17 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.17 | 2025-05-07 | 1 | 1 | hair graying; gray hair; canities; Polygonum multiflorum; Eriodictyon angustifolium; melanocyte stem cells (MSCs); microphthalmia-associated transcription factor (MITF); p38 mitogen-activated protein kinase (MAPK); oxidative stress; nuclear factor erythroid 2-related factor 2 (NRF2); norepinephrine; beta 2 adrenergic receptor (beta 2AR) | CORONARY-ARTERY-DISEASE; INDEPENDENT RISK MARKER; POLYGONUM-MULTIFLORUM THUNB.; MELANOCYTE STEM-CELLS; TRANSCRIPTION FACTOR; TOPICAL APPLICATION; FAMILY-HISTORY; P38 MAPK; FOLLICLE; MAINTENANCE | canities; Eriodictyon angustifolium; gray hair; hair graying; melanocyte stem cells (MSCs); microphthalmia-associated transcription factor (MITF); norepinephrine; nuclear factor erythroid 2-related factor 2 (NRF2); oxidative stress; p38 mitogen-activated protein kinase (MAPK); Polygonum multiflorum; β2 adrenergic receptor (β2AR) | Alkaloids; Dermatology; Endocrinology; Melanin; Norepinephrine; Oncology; Adrenergic receptors; Canity; Eriodictyon angustifolia; Gray hair; Hair graying; Melanocyte stem cell; Melanocyte stem cells; Microphthalmium-associated transcription factor; Nuclear factor erythroid 2-related factor 2; P38 mitogen-activated protein kinase; Polygonum multiflorum; Β2 adrenergic receptor; Oxidative stress | English | 2024 | 2024-09 | 10.3390/app14177450 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Intrinsic Mode-Based Network Approach to Examining Multiscale Characteristics of Sea Surface Temperature Variability | Variability of sea surface temperature (SST), characterized by various spatiotemporal scales, is a proxy of climate change. A network analysis combined with empirical mode decomposition is newly presented for examining scale-dependent spatial patterns of SST variability. Our approach is applied to SST anomaly variability in the East/Japan Sea (EJS), consisting of satellite-derived daily datasets of 0.25 degrees x 0.25 degrees resolution from 1981 to 2023. Through the spatial distribution of instantaneous energy in intrinsic modes and features of intrinsic-mode networks, scale-dependent spatiotemporal features are found. The season-specific spatial pattern of energy density is observed only for weekly to semiannual modes, while a persistent high-energy distribution in the tongue-shaped region from East Korea Bay (EKB) to the Sub-Polar Front (SPF) is observed only for annual-to-decadal modes. The seasonality is apparent in the time evolution of energy only for weekly-to-annual modes, with a peak in summer and an increasing trend since the 2010s. Hubs of intrinsic-mode networks are observed in the whole southern area (some northern part) of EJS during the summer (winter), only for monthly to semiannual modes. Regional communities are observed only for weekly to seasonal modes, while there is an inter-basin community with annual-to-biennial modes, incorporating two pathways of East Sea Intermediate Water (ESIW). | Lim, Gyuchang; Park, Jong-Jin | Kyungpook Natl Univ, Kyungpook Inst Oceanog, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea | Park, Jongjin/AAL-3484-2021 | 59883551700; 55717016100 | gclim@knu.ac.kr;jjpark@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.73 | 2025-05-07 | 2 | 2 | sea-surface-temperature anomaly; empirical mode decomposition; intrinsic mode; complex network theory | JAPAN SEA; INTERMEDIATE WATER; PROPER WATER; CIRCULATION; SERIES | complex network theory; empirical mode decomposition; intrinsic mode; sea-surface-temperature anomaly | English | 2024 | 2024-03 | 10.3390/app14051752 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Logic-Compatible Embedded DRAM Architecture for Multifunctional Digital Storage and Compute-in-Memory | The compute-in-memory (CIM) which embeds computation inside memory is an attractive scheme to circumvent von Neumann bottlenecks. This study proposes a logic-compatible embedded DRAM architecture that supports data storage as well as versatile digital computations. The proposed configurable memory unit operates in three modes: (1) memory mode in which it works as a normal dynamic memory, (2) logic-arithmetic mode where it performs bit-wise Boolean logic and full adder operations on two words stored within the memory array, and (3) convolution mode in which it executes digitally XNOR-and-accumulate (XAC) operation for binarized neural networks. A 1.0-V 4096-word x 8-bit computational DRAM implemented in a 45-nanometer CMOS technology performs memory, logic and arithmetic operations at 241, 229, and 224 MHz while consuming the energy of 7.92, 8.09, and 8.19 pJ/cycle. Compared with conventional digital computing, it saves energy and latency of the arithmetic operation by at least 47% and 46%, respectively. For VDD = 1.0 V, the proposed CIM unit performs two 128-input XAC operations at 292 MHz with an energy consumption of 20.8 pJ/cycle, achieving 24.6 TOPS/W. This marks at least 11.9x better energy efficiency and 38.8x better delay, thereby achieving at least 461x better energy-delay product than traditional 8-bit wide computing hardware. | Kim, Taehoon; Chung, Yeonbae | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | Kim, Taehoon/N-4124-2018 | 58260454500; 7404387325 | thkim7@ee.knu.ac.kr;ybchung@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | configurable embedded DRAM; logic operation; arithmetic operation; binary convolution; compute-in-memory | SRAM MACRO; MULTIBIT INPUT; WEIGHT; PRECISION; PROCESSOR | arithmetic operation; binary convolution; compute-in-memory; configurable embedded DRAM; logic operation | Associative storage; Boolean algebra; CMOS integrated circuits; Convolution; Digital arithmetic; Dynamic random access storage; Memory architecture; Memory management units; Probabilistic logics; Reconfigurable architectures; Static random access storage; Virtual storage; Arithmetic operations; Binary convolution; Compute-in-memory; Configurable embedded DRAM; Embedded DRAM; Energy; Logic operations; Memory units; Multifunctionals; Neumann; Computer circuits | English | 2024 | 2024-11 | 10.3390/app14219749 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Multi-Sensor Photoelectric Fire Alarm Device Implementation for Early Fire Detection in Campsites | With the growing popularity of leisure activities such as camping and glamping, the incidence of fires at camping sites has increased. This study focuses on improving the effectiveness of photoelectric fire alarm devices by incorporating temperature and humidity data for early fire detection in confined spaces, such as campsites. This study proposes a novel multi-sensor fire alarm system that dynamically adjusts fire detection threshold values based on temperature and humidity data collected by unmanned automatic weather observation systems. The prototype, which was implemented using Raspberry Pi and multiple sensors, demonstrated approximately 20% faster fire detection speed than existing photoelectric fire alarm systems, as verified through experiments in a simulated camping environment. The proposed approach is expected to advance fire alarm systems, enabling faster and more accurate fire detection in diverse environments, particularly at campsites. | Choi, Wonjun; Jung, Im Y. | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 59251189900; 18037522200 | 7373wj@naver.com;iyjung@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 1 | 2 | photoelectric type smoke detectors; fire detection considering humidity; fire detector for narrow closed places; multi-sensor fire detector; correlation between fire occurrence and humidity/temperature | correlation between fire occurrence and humidity/temperature; fire detection considering humidity; fire detector for narrow closed places; multi-sensor fire detector; photoelectric type smoke detectors | Humidity sensors; Laser beams; Photoelectric devices; Premixed flames; Risk management; Smoke detectors; Correlation between fire occurrence and humidity/temperature; Fire alarm; Fire detection; Fire detection considering humidity; Fire detector for narrow closed place; Fire occurrences; Multi sensor; Multi-sensor fire detector; Photoelectric type smoke detector; Photoelectrics; Fire alarm systems | English | 2024 | 2024-11 | 10.3390/app14219965 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Natural Eggshell Membrane Attenuates Chondrocyte Inflammation and Surgically Induced Osteoarthritis in Rats | Osteoarthritis (OA) is a degenerative joint disease that mainly occurs due to the cellular inflammatory response and the destruction of joint cartilage. Natural eggshell membrane (NEM), a byproduct of egg processing, might be a promising knee OA treatment because of its anti-inflammatory properties and resemblance to synovial membrane components. Therefore, we aimed to study the anti-inflammatory effects of NEM in OA, utilizing both in vitro experiments with primary chondrocytes and in vivo studies with a surgical rat model of knee OA. In vitro studies showed that NEM treatment improved cell viability in chondrocytes exposed to interleukin-1 alpha by upregulating chondrogenic genes and inhibiting enzymes that degrade the extracellular matrix (ECM). Furthermore, the anti-inflammatory effects of NEM were observed in chondrocytes induced by lipopolysaccharide. Administering NEM orally for 56 days after OA surgery resulted in enhanced joint swelling reduction and improved mobility in animal models, as well as an increase in bone density and cartilage compressive strength in a concentration-dependent manner. It inhibited inflammatory markers (5-lipoxygenase and prostaglandin E2) and extracellular matrix (ECM)-degrading enzymes (MMP-2 and MMP-9) in both the cartilage and synovium. Simultaneously, there was an upregulation in the expression of chondrogenic genes (Sox9, aggrecan, and Col-2). The histopathological and immunohistochemical analyses demonstrated that NEM's anti-inflammatory, anti-apoptotic, and chondrogenic properties contributed to the mitigation of joint degradation and synovial inflammation. Therefore, NEM is a potential alternative or functional food agent that addresses both anti-inflammatory and chondroprotective aspects in OA. | Kim, Jun-Il; Choi, Joo-Hee; Seo, Min-Soo; Kim, Jong-Kyu; Chun, Yoon-Seok; Kwon, Young-Sam; Ku, Sae-Kwang | Kyungpook Natl Univ, Coll Vet Med, Dept Vet Surg, Daegu 41566, South Korea; Daegu Gyeongbuk Med Innovat Fdn, Preclin Res Ctr, Daegu 41061, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Tissue Engn, Daegu 41566, South Korea; AriBnC Co Ltd, Eondong Ro 125 Beon Gil, Yongin 16985, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Anat & Histol, Gyongsan 38610, South Korea | 59197147600; 55882556800; 35254332100; 37090794500; 57209803368; 7403459426; 7006331005 | jondiki@knu.ac.kr;cjh522@kmedihub.re.kr;msseo@knu.ac.kr;jkkim@aribnc.com;ceochun@aribnc.com;kwon@knu.ac.kr;gucci200@dhu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 12 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 1 | 1 | osteoarthritis; natural eggshell membrane; anti-inflammation; anti-apoptosis; chondrogenesis | NECROSIS-FACTOR-ALPHA; ARTICULAR-CARTILAGE; PROTEOGLYCAN DEGRADATION; HIP OSTEOARTHRITIS; SUBCHONDRAL BONE; NITRIC-OXIDE; MODEL; TISSUE; ACID; KNEE | anti-apoptosis; anti-inflammation; chondrogenesis; natural eggshell membrane; osteoarthritis | English | 2024 | 2024-06 | 10.3390/app14125176 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Neuromodulation Effect According to Lesion Location After Dual-Mode Brain Stimulation in Patients with Subacute Stroke: A Preliminary Study | Dual-mode non-invasive brain stimulation using repetitive transcranial magnetic stimulation and transcranial direct current stimulation is known to help neurorehabilitation in patients with stroke. However, this neuromodulation effect may vary depending on the lesion location of patients with stroke, and the basis in lesion location for this is insufficient. This study aims to investigate the difference in neuromodulation effectiveness according to the lesion location after dual-mode brain stimulation using electroencephalography signals. Eight patients with ischemic subacute stroke and 11 healthy controls participated in this study. Brain stimulation was conducted in one session per day for a total of 10 days over the motor cortex, electroencephalography was measured for 5 min with eyes closed, and motor function was evaluated before and after dual-mode stimulation. The lesion location was divided into an infratentorial stroke (ITS) and a supratentorial stroke (STS) based on tentorium cerebelli. In addition, we focused on the mu and beta bands related to motor function. In terms of intrahemispheric connectivity, the mu weighted phase lag index over the contralesional primary motor cortex was significantly higher in only ITS before stimulation compared to healthy controls, and mu Granger causality over the ipsilesional primary motor cortex was significantly higher in both ITS and STS after stimulation compared to healthy controls. In contrast, from the perspective of interhemispheric connectivity, the laterality of beta Granger causality before stimulation in ITS was lower than that of healthy controls and significantly increased after stimulation. The effect of brain stimulation may vary depending on the lesion location of patients with stroke, and these findings provide indicative insights into effective dual-mode stimulation interventions for neurorehabilitation. | Lee, Minji; Park, Wanjoo; Park, Eunhee; Kweon, Soon-Jae; Kim, Yun-Hee | Catholic Univ Korea, Dept Biomed Software Engn, 43 Jibong Ro, Bucheon 14662, South Korea; New York Univ Abu Dhabi, Engn Div, Abu Dhabi 129188, U Arab Emirates; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, 807 Hoguk Ro, Daegu 41404, South Korea; Catholic Univ Korea, Sch Informat Commun & Elect Engn, Bucheon Si 14662, South Korea; Sungkyunkwan Univ, Dept Phys & Rehabil Med, Sch Med, 2066 Seobu Ro, Suwon 16419, South Korea | Lee, Minji/ABM-5019-2022; Kim, Yun-Hee/GVS-6426-2022 | 57196187332; 35485080700; 56107216400; 55000919500; 57020121600 | minjilee@catholic.ac.kr;wanjoo@nyu.edu;ehmdpark@naver.com;sj.kweon@catholic.ac.kr;yunkim@skku.edu; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | stroke; electroencephalography; non-invasive neuromodulation; transcranial magnetic stimulation; transcranial direct current stimulation | TRANSCRANIAL MAGNETIC STIMULATION; PRIMARY MOTOR CORTEX; CORTICOMOTOR EXCITABILITY; CONNECTIVITY; IMAGERY; PERFORMANCE; RECOVERY; TOOLBOX; NETWORK; HAND | electroencephalography; non-invasive neuromodulation; stroke; transcranial direct current stimulation; transcranial magnetic stimulation | Brain; Electrotherapeutics; Functional neural stimulation; Image segmentation; Magnetic after effect; Brain stimulation; Direct-current; Dual modes; Healthy controls; Neuromodulation; Non-invasive neuromodulation; Stroke; Transcranial; Transcranial direct current stimulation; Transcranial magnetic stimulation; Functional electric stimulation | English | 2024 | 2024-11 | 10.3390/app14219636 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optimization of Number of GCPs and Placement Strategy for UAV-Based Orthophoto Production | Unmanned aerial vehicles (UAVs) have been employed to perform aerial surveys in many industries owing to their versatility, relatively low cost, and efficiency. Ground control points (GCPs) are used for georeferencing to ensure orthophoto geolocation/positioning accuracy. In this study, we investigate the impact of the number and distribution of GCPs on the accuracy of orthophoto production based on images acquired by UAVs. A test site was selected based on regulatory requirements, and several scenarios were developed considering the specifications of the UAVs used in this study. The locations of GCPs were varied to obtain the results. Based on the results obtained for different numbers of GCPs per unit area and distribution of GCPs, it is shown that UAV-based platforms can be more extensively utilized in a range of applications. The findings of this study will significantly impact the development process of GCP automation algorithms and enable a more cost-effective approach when determining target sites for UAV-based orthophoto production. | Seo, Dong-Min; Woo, Hyun-Jung; Hong, Won-Hwa; Seo, Hyuncheol; Na, Wook-Jung | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea; Andong Sci Coll, Dept Fire Safety, Andong 36616, South Korea | ; Seo, Hyuncheol/ABC-5117-2020 | 57222555933; 57219244497; 7401527968; 56083741500; 57991059600 | hongwh@knu.ac.kr;charles@knu.ac.kr;wooksna@gmail.com; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.73 | 2025-05-07 | 2 | 2 | ground control points; unmanned aerial photogrammetry; unmanned aerial vehicle; orthophoto; digital elevation model | QUALITY | digital elevation model; ground control points; orthophoto; unmanned aerial photogrammetry; unmanned aerial vehicle | English | 2024 | 2024-04 | 10.3390/app14083163 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Performance Verification and Evaluation of Semi-Active Actuator System Using Quarter Car Lab Simulation with RLDA Data | This study outlines a methodology for determining the durability specifications of electronically controlled dampers by examining performance degradation observed on actual driving roads. It identifies areas of performance decline and the primary causes affecting major actuator dampers. Traditionally, the durability performance of automobile parts has been assessed by calculating damage based on load profiles. However, analyzing actual road conditions is essential because the control commands of electronically controlled suspension systems change in real time according to load conditions. Simulations based on Road Load Data Acquisition (RLDA) use statistically independent representative road surfaces to assess damper deterioration performance. Following this analysis, a rig test of the damper is performed to establish the durability specifications for damper actuator products. The primary form of performance degradation observed was a change in the tensile damping force, which was more substantial than the degradation observed on the compression side. Oil leakage and cavitation were identified as significant influencing factors from a Failure Mode and Effects Analysis (FMEA) perspective. The study concludes that additional design research is necessary, focusing on damper oil and leakage, while also considering the control algorithm's effects in designing electronically controlled dampers. | Lee, Jeongwoo; Lee, Jaepoong | Kyungpook Natl Univ, Sch Automot Engn, Daegu 41566, South Korea; Chungbuk Natl Univ, Dept Intelligent Syst & Robot, Cheongju 28644, South Korea | 59448682100; 57189847113 | jeongwoolee@knu.ac.kr;ske03005@cbnu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 22 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | continuous variable damper; semi-active suspension; RLDA; quarter car lab; FMEA; durability | continuous variable damper; durability; FMEA; quarter car lab; RLDA; semi-active suspension | Active suspension systems; Automobile suspensions; Emotional intelligence; Hydraulic fluids; Invariance; Continuous variable damper; Continuous variables; Failure mode and effects analysis; Load data; Quarter car lab; Quarter-car; Road load data acquisition; Road loads; Semi active suspension; Variable dampers; Damage detection | English | 2024 | 2024-11 | 10.3390/app142210093 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Photocatalytic Oxidization Based on TiO2/Au Nanocomposite Film for the Pretreatment of Total Phosphorus (TP) | Phosphorus, an essential rare element in aquatic ecosystems, plays a key role in maintaining ecosystem balance. However, excess phosphorus leads to eutrophication and algal proliferation. To prevent eutrophication, the pretreatment and measuring of the concentration of total phosphorus (TP) is crucial. Compared to conventional TP pretreatment equipment (autoclave), a lab-on-a-chip detection device fabricated using micro-electromechanical system technology and titania (TiO2) as a photocatalyst is more convenient, efficient, and cost-effective. However, the wide bandgap of TiO2 (3.2 eV) limits photocatalytic activity. To address this problem, this paper describes the preparation of a TiO2/Au nanocomposite film using electron-beam evaporation and atomic-layer deposition, based on the introduction of gold film and TiO2 to a quartz substrate. The photocatalytic degradation properties of TiO2/Au nanocomposite films with thicknesses of 1, 2, 3, and 4 nm were assessed using rhodamine B as a pollutant. The experimental results demonstrate that the deposition of gold films with different thicknesses can enhance photocatalytic degradation efficiency through synergetic reactions in the charge separation process on the surface. The optimal photocatalytic efficiency is achieved when the deposition thickness is 2 nm, and it decreases with further increase in the thickness. When the photocatalytic reaction time is 15 min, the lab-on-a-chip (LOC) device with a 2-nm-thick gold layer and autoclave exhibits a similar TP pretreatment performance. Therefore, the proposed LOC device based on photocatalytic technology can address the limitations of conventional autoclave equipment, such as large volumes, long processing times, and high costs, thereby satisfying the growing demand for on-site evaluation. | Wang, Jiajie; Kim, Seung-Deok; Lee, Jae-Yong; Kim, June-Soo; Jang, Noah; Kim, Hyunjun; Kim, Da-Ye; Nam, Yujin; Han, Maeum; Kong, Seong-Ho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | Lee, Jae/P-8895-2017 | 58130764600; 57223370762; 57223374818; 57314355500; 58130629700; 59446567300; 57279831500; 59289058300; 55931924500; 57204537951 | jiajie0505@gmail.com;shkong@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.73 | 2025-05-07 | 2 | 2 | total phosphorus; pretreatment; photocatalyst; lab-on-a-chip; TiO2/Au nanocomposite film | ANNEALING TEMPERATURE; DIGESTION METHOD; EUTROPHICATION; AU; NITROGEN; SURFACES | lab-on-a-chip; photocatalyst; pretreatment; TiO<sub>2</sub>/Au nanocomposite film; total phosphorus | English | 2024 | 2024-03 | 10.3390/app14051774 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Pseudo-Labeling and Time-Series Data Analysis Model for Device Status Diagnostics in Smart Agriculture | This study proposes an automated data-labeling model that combines a pseudo-labeling algorithm with waveform segmentation based on Long Short-Term Memory (LSTM) to effectively label time-series data in smart agriculture. This model aims to address the inefficiency of manual labeling for large-scale data generated by agricultural systems, enhancing the performance and scalability of predictive models. Our proposed method leverages key features of time-series data to automatically generate labels for new data, thereby improving model accuracy and streamlining data processing. By automating the labeling process, we reduce dependence on manual labeling, which is often labor-intensive and prone to errors in large datasets. This approach enables the efficient preparation of labeled data for applications such as anomaly detection, pattern recognition, and predictive modeling in smart agriculture. Experimental results demonstrate that the automated labeling model achieves 89% accuracy in agricultural environments and reduces data processing time by 30%. Future research will focus on extending the model's applicability to diverse agricultural settings, enhancing generalization performance, and improving real-time processing capabilities, thereby advancing intelligent and sustainable smart agriculture systems. | Jung, Minwoo; Kim, Dae-Young | Kyungpook Natl Univ, Ctr Selforganizing Software, Daegu 41566, South Korea; Soonchunhyang Univ, Dept Comp Software Engn, Asan 31538, South Korea | 55517112600; 58378650900 | jungminwoo80@gmail.com;dyoung.kim@sch.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 22 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 1 | 1 | smart agriculture; pseudo-labeling; time-series data; machine learning automation; IoT device status monitoring | NETWORK; CITIES | IoT device status monitoring; machine learning automation; pseudo-labeling; smart agriculture; time-series data | Device status; IoT device status monitoring; Labelings; Learning automation; Machine learning automation; Machine-learning; Pseudo-labeling; Smart agricultures; Status monitoring; Time-series data | English | 2024 | 2024-11 | 10.3390/app142210371 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Quality Analysis of Unmanned Aerial Vehicle Images Using a Resolution Target | Unmanned aerial vehicle (UAV) photogrammetry is an emerging means of acquiring high-precision rapid spatial information and data because it is cost-effective and highly efficient. However, securing uniform quality in the results of UAV photogrammetry is difficult due to the use of low-cost navigation devices, non-surveying cameras, and rapid changes in shooting locations depending on the aircraft's behavior. In addition, no specific procedures or guidelines exist for performing quantitative quality tests or certification methods on UAV images. Additionally, test tools for UAV image quality assessment only use the ground sample distance (GSD), often resulting in a reduced image quality compared with that of manned aircraft images. In this study, we performed a modulation transfer function (MTF) analysis using a slanted edge target and a GSD analysis to confirm the necessity of MTF analysis in UAV image quality assessments. In this study, we aimed to address this issue by conducting a modulation transfer function (MTF) analysis using a slanted edge target and a ground sample distance (GSD) analysis. This was carried out to confirm the necessity of MTF analysis in evaluating UAV image quality. Furthermore, we analyzed the impact of flight height and mounted sensors on image quality at different study sites. | Kim, Jin-Hyo; Sung, Sang-Min | Kyungpook Natl Univ, Dept Landscape Architecture, Daegu 41561, South Korea; Korea Forest Conservat Assoc, CCZ Forest Land Management Off, Daejeon 35262, South Korea | 57226774198; 58827951500 | jhkim85@knu.ac.kr;sungsm@kfca.re.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 1 | 2 | unmanned aerial vehicle (UAV) photogrammetry; ground sample distance (GSD); modulation transfer function (MTF); image quality | ground sample distance (GSD); image quality; modulation transfer function (MTF); unmanned aerial vehicle (UAV) photogrammetry | English | 2024 | 2024-03 | 10.3390/app14052154 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Real-Time Forward Head Posture Detection and Correction System Utilizing an Inertial Measurement Unit Sensor | Forward head posture (FHP) has become a prevailing health issue in modern society as people spend more time on computers and smartphones. FHP is a posture where the head is forward and the anterior and posterior curvatures of the lower cervical and upper thoracic spines are both, respectively, exaggerated. FHP is often associated with neck pain, bad static balance, and hunched shoulders or back. To prevent this, consciously maintaining good posture is important. Therefore, in this study, we propose a system that gives users real-time, accurate information about their neck posture, and it also encourages them to maintain a good posture. This inexpensive system utilizes a single inertial measurement unit sensor and a Raspberry Pi system to detect the changes in state that can progress to an FHP. It retrieves data from the sensor attached to the user's cervical spine to indicate their real-time posture. In a real-world office environment experiment with ten male participants, the system accurately detected the transition to the FHP state for more than 10 s, with a delay of less than 0.5 s, and it also provided personalized feedback to encourage them to maintain good posture. All ten participants recognized that their average craniovertebral angle had to be increased after receiving visual alerts regarding their poor postures in real time. The results indicate that the system has potential for widespread applications. | Park, Gyumin; Jung, Im Y. | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 59369940700; 18037522200 | qkrrbals0828@naver.com;iyjung@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 1 | 1 | inertial measurement unit sensor; forward head posture; wearable sensor; real-time system; personalized feedback | NECK; RELIABILITY; DISABILITY; PRESSURE; BALANCE; PAIN | forward head posture; inertial measurement unit sensor; personalized feedback; real-time system; wearable sensor | Real time systems; Forward head posture; Health issues; Inertial measurement unit sensor; Inertial measurements units; Personalized feedback; Posture detection; Real - Time system; Real- time; Smart phones; Thoracic spine; Wearable sensors | English | 2024 | 2024-10 | 10.3390/app14199075 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Retrograde Study Using Radiographic Comparison of Bone Fill Observed after Guided Tissue Regeneration by the Type of Periodontal Bone Defect | Background and Objectives: The current study aimed to compare the extent of bone growth achieved after guided tissue regeneration (GTR) based on the location and nature of the initial periodontal lesion. Materials and Methods: The study sample included 80 patients who underwent GTR at Kyungpook National University Dental Hospital since 2012 and were radiologically followed up for at least 2 years after treatment. The patients were divided into four groups based on the location (maxilla and mandible) and nature (furcation involvement and intrabony defects) of the lesion. Differences in bone levels before and after treatment were analyzed. Additionally, a comparison of outcomes based on the type of bone graft material used was conducted. Statistical analysis included a comparison of groups using a t-test, assuming equal variance. Results: The proportion of bone growth observed in the maxillary furcation, mandibular furcation, maxillary intrabony, and mandibular intrabony lesions was 26%, 22%, 31%, and 34%, respectively. No statistically significant differences in the amount of bone fill were observed between the groups. However, a significant positive correlation was found between the initial depth of the bone defect and the amount of bone fill observed after treatment. Conclusions: Contrary to previous evidence, the current study observed no significant differences in the amount of bone fill after GTR based on the location and nature of the lesion. Furthermore, the amount of bone regenerated was directly proportional to the initial depth of the alveolar bone defect. | Do, Woo-Seok; Kim, Yong-Gun; Suh, Jo-Young; Kim, Jin-Wook; Lee, Jae-Mok | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Surg, Daegu 41940, South Korea | 59072915500; 55622694400; 7201514992; 55862646000; 17346330000 | vocaleo@naver.com;leejm@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-04-16 | 0 | 0 | periodontal regeneration; guided tissue regeneration; bone fill; periodontal intrabony defect; furcation involvement; radiographic comparison | INTRABONY DEFECTS; FURCATION INVOLVEMENT; ATTACHMENT FORMATION; BARRIER MEMBRANE; THERAPY; PRINCIPLES; MAXILLARY; SURVIVAL | bone fill; furcation involvement; guided tissue regeneration; periodontal intrabony defect; periodontal regeneration; radiographic comparison | English | 2024 | 2024-01 | 10.3390/app14010179 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
