| ○ | ○ | Article | Sea surface temperature warming to inhibit mitigation of tropical cyclone destructiveness over East Asia in El Niño | Given their conditions to reside in and intensify longer over warm oceans, tropical cyclones (TCs) in the western North Pacific (WNP) present a stronger lifetime maximum intensity during El Nino than during La Nina. By using observational data, we found that the anomalously cool sea surface temperature (SST)s in the basin act as effective barriers against intense TCs approaching East Asia during El Nino, weakening their destructiveness at landfall. Based on our high-resolution pseudo-global-warming simulations, the basin-wide 2K SST warming within the WNP basin can, however, shatter this cool SST barrier, exposing East Asia to more destructive TCs during El Nino, compared to those during La Nina. Considering that the 2K warmer WNP will likely occur in the mid-21st century under a high emission scenario and in the late 21st century under a moderate emission scenario, our findings support that more aggressive efforts of global warming mitigation are needed. | Park, Doo-Sun R.; Seo, Eunkyo; Lee, Minkyu; Cha, Dong-Hyun; Kim, Dasol; Ho, Chang-Hoi; Lee, Myong-In; Kim, Hyeong-Seog; Min, Seung-Ki | Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Environm Atmospher Sci, Busan 48513, South Korea; George Mason Univ, Ctr Ocean Land Atmosphere Studies, Fairfax, VA 22030 USA; Pohang Univ Sci & Technol, Div Environm Sci & Engn, Pohang 37673, Gyeongbuk, South Korea; Ulsan Natl Inst Sci & Technol, Dept Civil Urban Earth & Environm Engn, Ulsan 44919, South Korea; Univ Florida, Dept Geog, Gainesville, FL 32611 USA; Ewha Womans Univ, Dept Climate & Energy Syst Engn, Seoul 03760, South Korea; Korea Maritime & Ocean Univ, Ocean Sci & Technol Sch, Busan 49112, South Korea; Yonsei Univ, Inst Convergence Res & Educ Adv Technol, Seoul 03722, South Korea | Lee, Myong-In/F-3578-2010; Seo, Eunkyo/ABH-6269-2020; Ho, Chang-Hoi/H-8354-2015; Min, Seung-Ki/B-1431-2010; Kim, Hyeong-Seog/F-4496-2010; Cha, Dong-Hyun/F-4901-2015; Kim, Dasol/GWR-1499-2022; Park, Doo-Sun/U-9448-2019 | 37117659000; 57201983930; 57211620300; 55418553100; 56420697800; 7404653593; 58530782000; 35487531500; 57192273006 | dsrpark@knu.ac.kr;dhcha@unist.ac.kr; | NPJ CLIMATE AND ATMOSPHERIC SCIENCE | NPJ CLIM ATMOS SCI | 2397-3722 | 7 | 1 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 8.4 | 5.0 | 1.99 | 2025-05-07 | 6 | 6 | INTERANNUAL VARIATION; INTENSITY; NINO; ENSO; EVENTS; MODEL; INTENSIFICATION; DEPENDENCE; LANDFALL; IMPACTS | Far East; Pacific Ocean; Pacific Ocean (North); computer simulation; El Nino; global warming; image resolution; La Nina; sea surface temperature; tropical cyclone; warming | English | 2024 | 2024-01-20 | 10.1038/s41612-023-00556-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Uncertainties in measuring precipitation hinders precise evaluation of loss of diversity in biomes and ecotones | Assessing changes in the distribution of biological communities that share a climate (biomes) is essential for estimating their vulnerability to climate change. We use CMIP6 climate models to calculate biome changes as featuring in classifications such as Holdridge's Life Zones (climate envelopes). We found that transitional zones between biomes (known as ecotones) are expected to decline under all climate change scenarios, but also that model consensus remains low. Accurate assessments of diversity loss are limited to certain areas of the globe, while model consensus is still poor for half of the planet. We identify where there are robust estimates of changes in biomes and ecotones, and where consensus is lacking. We argue that caution should be exercised in measuring biodiversity loss in the latter, but that greater confidence can be placed in the former. We find that shortcomings in the life zone classification are related to inter-model variability, which ultimately depends on a larger problem, namely the accurate estimation of precipitation compared to CRU. Application of the methodology to other climate classifications confirms the findings. | Navarro, Andres; Lee, Gyuwon; Martin, Raul; Tapiador, Francisco J. | Univ Castilla La Mancha UCLM, Inst Environm Sci ICAM, Earth & Space Sci ESS Grp, Avda Carlos III s-n, Toledo 45071, Spain; Kyungpook Natl Univ, Ctr Atmospher Remote Sensing CARE, Dept Atmospher Sci, Daegu, South Korea; Univ Castilla La Mancha UCLM, Dept Math, Avda Carlos III s-n, Toledo 45071, Spain | Navarro, Andrés/AAG-7272-2019; Martín Martín, Raúl/F-2331-2016; Martin Martin, Raul/F-2331-2016; Tapiador, Francisco/D-2781-2009 | 57193451684; 7404852271; 58867259000; 6602960153 | Andres.Navarro@uclm.es; | NPJ CLIMATE AND ATMOSPHERIC SCIENCE | NPJ CLIM ATMOS SCI | 2397-3722 | 7 | 1 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2024 | 8.4 | 5.0 | 1.99 | 2025-05-07 | 4 | 5 | CLIMATE-CHANGE; BIODIVERSITY LOSS; BIAS CORRECTION; GLOBAL CLIMATE; VEGETATION; MODEL; TEMPERATURE; EVAPOTRANSPIRATION; FORESTS; ZONES | accuracy assessment; biodiversity; biome; climate change; climate classification; climate effect; climate modeling; CMIP; community resource management; community structure; ecotone; global perspective; measurement method; precipitation (climatology); precision; species diversity; uncertainty analysis; vulnerability | English | 2024 | 2024-02-02 | 10.1038/s41612-024-00581-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Aberrant activation of hippocampal astrocytes causes neuroinflammation and cognitive decline in mice | Reactive astrocytes are associated with neuroinflammation and cognitive decline in diverse neuropathologies; however, the underlying mechanisms are unclear. We used optogenetic and chemogenetic tools to identify the crucial roles of the hippocampal CA1 astrocytes in cognitive decline. Our results showed that repeated optogenetic stimulation of the hippocampal CA1 astrocytes induced cognitive impairment in mice and decreased synaptic long-term potentiation (LTP), which was accompanied by the appearance of inflammatory astrocytes. Mechanistic studies conducted using knockout animal models and hippocampal neuronal cultures showed that lipocalin-2 (LCN2), derived from reactive astrocytes, mediated neuroinflammation and induced cognitive impairment by decreasing the LTP through the reduction of neuronal NMDA receptors. Sustained chemogenetic stimulation of hippocampal astrocytes provided similar results. Conversely, these phenomena were attenuated by a metabolic inhibitor of astrocytes. Fiber photometry using GCaMP revealed a high level of hippocampal astrocyte activation in the neuroinflammation model. Our findings suggest that reactive astrocytes in the hippocampus are sufficient and required to induce cognitive decline through LCN2 release and synaptic modulation. This abnormal glial-neuron interaction may contribute to the pathogenesis of cognitive disturbances in neuroinflammation-associated brain conditions. | Kim, Jae-Hong; Michiko, Nakamura; Choi, In-Sun; Kim, Yujung; Jeong, Ji-Young; Lee, Maan-Gee; Jang, Il-Sung; Suk, Kyoungho | Kyungpook Natl Univ, Sch Med, Dept Pharmacol, Daegu, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu, South Korea; Kyungpook Natl Univ, Brain Korea four KNU Convergence Educ Program Biom, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Pharmacol, Daegu, South Korea; Korea Brain Res Inst, Daegu, South Korea | 55926599800; 59214847600; 8414266600; 59214552400; 57194441446; 7409123157; 7102177910; 7005114595 | jis7619@knu.ac.kr;ksuk@knu.ac.kr; | PLOS BIOLOGY | PLOS BIOL | 1544-9173 | 1545-7885 | 22 | 7 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOLOGY | 2024 | 7.2 | 5.1 | 6.57 | 2025-05-07 | 14 | 13 | LONG-TERM POTENTIATION; NMDA RECEPTOR; SYNAPTIC PLASTICITY; OPTOGENETIC STIMULATION; SPINAL ASTROCYTES; DEPENDENT MEMORY; BRAIN-INJURY; DUAL ROLE; LIPOCALIN-2; CALCIUM | Animals; Astrocytes; CA1 Region, Hippocampal; Cognitive Dysfunction; Disease Models, Animal; Hippocampus; Lipocalin-2; Long-Term Potentiation; Male; Mice; Mice, Inbred C57BL; Mice, Knockout; Neuroinflammatory Diseases; Neurons; Optogenetics; Receptors, N-Methyl-D-Aspartate; clozapine; glyceraldehyde 3 phosphate dehydrogenase; interleukin 1beta; messenger RNA; n methyl dextro aspartic acid receptor 1; neutrophil gelatinase associated lipocalin; tumor necrosis factor; Lcn2 protein, mouse; n methyl dextro aspartic acid receptor; neutrophil gelatinase associated lipocalin; animal cell; animal experiment; animal model; animal tissue; Article; astrocyte; Barnes maze test; behavior; brain tissue; cell culture; cell fractionation; cell viability assay; cognitive defect; electrophysiology; enzyme linked immunosorbent assay; gene expression; glia cell; hippocampus; immunofluorescence; immunohistochemistry; in vivo study; male; microdialysis; microglia; mouse; MTT assay; nerve cell; nervous system function; nervous system inflammation; nonhuman; optogenetics; passive avoidance test; photometry; real time polymerase chain reaction; synaptic longterm potentiation; viral gene delivery system; Western blotting; Y-maze test; animal; C57BL mouse; disease model; etiology; genetics; hippocampal CA1 region; knockout mouse; long term potentiation; metabolism; nerve cell; pathology | English | 2024 | 2024-07 | 10.1371/journal.pbio.3002687 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Adhesive-free PDMS/PUA bilayer using selective photopolymerization for transparent, attachable, and wearable triboelectric nanogenerator | Polydimethylsiloxane (PDMS) is a widely used elastomer substrate in various fields, including wearable devices, because of its diverse advantages. However, PDMS has low stretchability and lack of adhesion, thus requires additive adhesives, such as conventional tapes, which have potential to cause skin trauma. Meanwhile, polyurethane acrylate (PUA) is also a broadly used elastomer given its various advantages, such as biocompatibility and mechanical properties. This study introduces, for the first time, a novel laser process method to form an adhesive-free PDMS/PUA bilayer film. By adjusting UV laser scanning parameters, the interfacial bonding between the PDMS and PUA can be improved without additional additives. The fabricated PDMS/PUA bilayer showed high transparency, improved mechanical properties, and adhesiveness properties. Combining with PUA (as a backbone and adhesive layer) and PDMS (as a triboelectric layer), the PDMS/PUA bilayer was further used to fabricate a transparent, attachable, and stretchable PDMS/PUA-based triboelectric nanogenerator (PP-TENG) device. The transparent attachable PP-TENG successfully detected minute human motions and functioned as a virtual piano keyboard and a virtual computer keyboard when attached to an arbitrary paper. | Lee, Hee Jin; Kim, Hyeonwoo; Kim, Tae Sung; Kim, Hee Yeong; Mun, Jonghwan; Choi, Geonjun; Jeong, Hoon Eui; Yeo, Junyeob | Kyungpook Natl Univ, Dept Phys, Novel Appl Nano Opt Lab, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 80 Daehak Ro, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol UNIST, Dept Mech Engn, Ulsan 44919, South Korea | Yeo, Junyeob/I-1287-2013 | 57214747647; 57223908123; 58625699200; 57777769800; 57555832500; 57222136967; 35490647000; 58692645200 | hoonejeong@unist.ac.kr;junyeob@knu.ac.kr; | NANO ENERGY | NANO ENERGY | 2211-2855 | 2211-3282 | 121 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2024 | 17.1 | 5.1 | 3.98 | 2025-05-07 | 16 | 17 | Polydimethylsiloxane; Polyurethane; Bilayer; Photopolymerization; Self-adhesive; Triboelectric nanogenerator | POLYDIMETHYLSILOXANE COMPOSITES; ELECTRODE; TEXTILES | Bilayer; Photopolymerization; Polydimethylsiloxane; Polyurethane; Self-adhesive; Triboelectric nanogenerator | Additives; Adhesives; Biocompatibility; Nanogenerators; Photopolymerization; Polydimethylsiloxane; Silicones; Triboelectricity; Virtual reality; Wearable technology; Bi-layer; Bi-layer films; Laser process; Nanogenerators; Photo polymerization; Polyurethane/acrylate; Process methods; Self-adhesive; Triboelectric nanogenerator; Wearable devices; Polyurethanes | English | 2024 | 2024-03 | 10.1016/j.nanoen.2024.109274 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | AHP and FAHP-based multi-criteria analysis for suitable dam location analysis: a case study of the Bagmati Basin, Nepal | The Bagmati River Basin is experiencing significant water stress due to a reduction of surface and groundwater resources, especially during the dry season. The basin's heavy reliance on monsoon-dominated precipitation, without the buffer of snow or glacier melt, exacerbates these issues. Dam construction is seen as a viable solution for maintaining river flow and regulating river ecosystems. Thus, this study leveraged multi-criteria decision-making tools, particularly the analytical hierarchy process (AHP) and fuzzy AHP (FAHP) in conjunction with the Geographic Information System(GIS), to identify suitable dam construction sites in the Bagmati River Basin. Through an extensive literature review, nine criteria were identified: stream density, rainfall, slope, land use, elevation, soil type, distance from faults, distance from settlements, and distance from roads. Pairwise comparison matrices, based on expert surveys, were used to assign weights to each criterion, with validation against existing and proposed dams. Results show that approximately 31% of the basin area is suitable for dam construction, with about 4.45% area being highly suitable. FAHP only slightly outperforms AHP in assessing existing dam locations, demonstrating the robustness of both methodologies. For the validation of suitability analysis, location of existing dams are compared. While Nepal is not generally water-stressed, inter-seasonal water availability is high. Dam construction for multiple uses is nascent in Nepal, and location analysis studies are rare. The methodology used here can be replicated in other regions, offering valuable insights for decision-makers. | Bastola, Shiksha; Shakya, Binay; Seong, Yeongjeong; Kim, Beomgu; Jung, Younghun | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju, South Korea; Nepal Engn Coll, Dept Civil Engn, Bhaktapur, Nepal | 57202955572; 59322132500; 57202956507; 59322132600; 55195880200 | y.jung@knu.ac.kr; | STOCHASTIC ENVIRONMENTAL RESEARCH AND RISK ASSESSMENT | STOCH ENV RES RISK A | 1436-3240 | 1436-3259 | 38 | 11 | SCIE | ENGINEERING, CIVIL;ENVIRONMENTAL SCIENCES;STATISTICS & PROBABILITY;WATER RESOURCES;ENGINEERING, ENVIRONMENTAL | 2024 | 3.6 | 5.1 | 1 | 2025-05-07 | 3 | 5 | Dam locations; Multi-criteria decision making; AHP; FAHP; Bagmati basin | ANALYTIC HIERARCHY PROCESS; WATER-RESOURCES; DECISION-ANALYSIS; GIS; IDENTIFICATION; IMPACTS; SITES; RIVER | AHP; Bagmati basin; Dam locations; FAHP; Multi-criteria decision making | Bagmati Basin; Dams; Decision making; Hierarchical systems; Rivers; Snow making; Soil surveys; Surface water resources; Analytical Hierarchy Process; Bagmati basin; Dam construction; Dam location; Fuzzy AHP; Location analysis; Multi criteria decision-making; Multicriteria decision-making; Multicriterion decision makings; River basins; analytical hierarchy process; dam construction; GIS; location decision; multicriteria analysis; Groundwater resources | English | 2024 | 2024-11 | 10.1007/s00477-024-02799-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced energy harvesting of fibrous composite membranes via plasma-piezopolymer interaction | Electroactive sites and crystallinity play a key role to improve the energy conversion performance of piezoelectric polymeric composites. However, these characteristics are attained through time-consuming thermal annealing (TA), which limits the practicality of flexible piezoelectric harvesters (f-PEHs). Here, a short-time plasma annealing (PA) technique was introduced to piezoelectric composite fibers (PCFs) for rapid crystallization and enhanced electroactive beta-phase of polymer. The percentage of change in crystallinity of 10-minute PA treated PCF is 20 % compared to TA-treated PCF (annealing time = 2 h), which results in a higher voltage of 2.4 times and current of 3.8 times than the TA-based f-PEH. Finite element analysis confirmed the optimal PA treatment duration and superior performance of PA-treated PCFs. Further PA treated f-PEH was tested for vibration sensor by attaching it to a circulator pipe, confirming its high potential for accurately detecting variations in flow velocity (8-28 L/min). These results demonstrate that PA is an efficient technique for producing highperformance f-PEHs with an increased crystallinity (Xc =22.81 %) in a short time (10 minutes), offering a practical solution for consumer electronic devices and wireless sensors. | Park, Hyeon Jun; Bae, Bitna; Jang, HakSu; Hyeon, Dong Yeol; Lee, Dong Hun; Kim, Gwang Hyun; Kim, Cheol Min; Alluri, Nagamalleswara Rao; Baek, Changyeon; Lee, Min-Ku; Lee, Gyoung-Ja; Park, Kwi-Il | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Innovat Semicond Educ & Res Ctr Future Mobil, Daegu 41566, South Korea; Korea Adv Inst Sci & Technol, Dept Mat Sci & Engn, Daejeon 34141, South Korea; Korea Atom Energy Res Inst, Nucl Syst Integr Sensing & Diag Res Div, Daejeon 34057, South Korea; Kyungpook Natl Univ, Res Inst Automot Parts & Mat, Daegu 41566, South Korea | Hyeon, Dong Yeol/HNR-5711-2023; Lee, Dong/N-6131-2019; Park, Kwiil/LKN-9445-2024 | 58859176900; 59302327300; 59302327400; 57209099464; 59444729800; 59302289000; 59441985400; 56527074500; 57095549400; 59302175900; 8588965200; 35280874200 | leegj@kaeri.re.kr;kipark@knu.ac.kr; | NANO ENERGY | NANO ENERGY | 2211-2855 | 2211-3282 | 131 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2024 | 17.1 | 5.1 | 0.57 | 2025-05-07 | 2 | 2 | Piezoelectric; Composite fiber; Flexible; Energy harvester; Crystallinity; Plasma annealing | SURFACE MODIFICATION; PVDF; CRYSTALLINITY; TEMPERATURE; IMPACT; FILMS | Composite fiber; Crystallinity; Energy harvester; Flexible; Piezoelectric; Plasma annealing | Conducting polymers; Elastomers; Energy harvesting; Fibrous membranes; Piezoelectric devices; Composite fibres; Cristallinity; Energy Harvester; Flexible; Performance; Piezoelectric; Piezoelectric composite; Piezoelectric harvester; Plasma annealing; Thermal-annealing; Piezoelectricity | English | 2024 | 2024-12-01 | 10.1016/j.nanoen.2024.110299 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Online Electric Vehicle Charging Strategy in Residential Areas With Limited Power Supply | Electric vehicle (EV) demand is considerably increasing, aided by battery technology development and government policy support. Therefore, it is necessary to consider various charging infrastructures and secure sufficient power to support this. In several cities or countries, a large population lives in a small area, and the supply of large residential complexes such as apartments is common. Given that old apartments may not have sufficient power capacity, it is challenging to secure additional power for charging EVs. In particular, power shortages can intensify during high power usage, such as the summer season, and may become an obstacle to the spread of EVs. Therefore, an efficient charging strategy for residential complexes must be established under the condition of limited power supply. This study proposes two scheduling methods to optimally charge EVs in residential complexes considering limited power supply. The proposed scheduling algorithms are thoroughly examined through extensive simulations with parking data collected from real situations and are demonstrated to be effective for online EV charging systems. | Yoon, Dong-Hee; Seo, Hyoju; Lee, Jungwon; Kim, Yongtae | Kyungil Univ, Sch Railway, Gyongsan 38428, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Samsung Elect, Memory Business, Hwaseong 18448, South Korea | ; Yoon, Dong-Hee/S-8819-2019; Seo, Hyoju/GSD-8672-2022 | 35744347400; 57215662369; 57219710729; 55699627900 | dhyoon@kiu.kr;hyoju@knu.ac.kr;jjung1.lee@samsung.com;yongtae@knu.ac.kr; | IEEE TRANSACTIONS ON SMART GRID | IEEE T SMART GRID | 1949-3053 | 1949-3061 | 15 | 3 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2024 | 9.8 | 5.1 | 1.43 | 2025-05-07 | 3 | 5 | Electric vehicle charging; Power supplies; Buildings; Optimal scheduling; Urban areas; Energy management; Data models; Electric vehicle; online charging scheduling; battery; limited power supply; residential building; parking lot | MANAGEMENT | battery; Electric vehicle; limited power supply; online charging scheduling; parking lot; residential building | Apartment houses; Charging (batteries); Electric power systems; Energy management; Online systems; Scheduling algorithms; Secondary batteries; Battery; Electric vehicle charging; Limited power supply; Online charging; Online charging scheduling; Optimal scheduling; Parking lots; Power supply; Residential building; Urban areas; Electric vehicles | English | 2024 | 2024-05 | 10.1109/tsg.2023.3339788 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Review | Review on dendrite formation of Mg metal anode and its prevention | Rechargeable batteries with metal anodes are recognized as a good option to respond to contentious demand for increasing energy density. However, dendric metal deposition is uncontrollable and causes low Coulomb efficiency and short-circuiting, leading to serious safety issues. Dendric deposition is observed very often in Li and Na metals, while dendrite-free deposition with 100 % Coulomb efficiency is achieved in Mg metal. Additionally, high natural abundance, good machinability, and high stability in ambient conditions of Mg metal make Mg metal anode an ideal metal anode. In 2017, dendric deposition of Mg metal is discovered and possible dendric Mg deposition is also proved by the simulation. These studies reclaim a new research area in developing rechargeable Mg batteries. Recently, the mechanism and suppression of dendric Mg deposition have been studied intensively. In this mini-review, the dendric deposition of Mg metal and its prevention are reviewed. The features of Mg dendrite are studied compared to those of Li and Na dendrites. After that, research on preventing and suppressing Mg dendrite formation is analyzed and summarized. Finally, perspectives and challenges of Mg metal anode are proposed. | Yan, Binggong; Karuppiah, Chelladurai; Walle, Kumlachew Zelalem; Abdelaal, Mohamed M.; Kotobuki, Masashi; Lu, Li | Huaqiao Univ, Fujian Key Lab Special Energy Mfg, Xiamen 361021, Peoples R China; Kyungpook Natl Univ, Dept Chem, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, 80 Daehakro, Daegu 41566, South Korea; Ming Chi Univ Technol, Battery Res Ctr Green Energy, 84 Gungjuan Rd, New Taipei 24301, Taiwan; Univ Gondar, Coll Nat & Computat Sci, Dept Chem, Meraki St 196, Gondar, Ethiopia; Tabbin Inst Met Studies, Helwan 109, Cairo 11421, Egypt; Chang Gung Univ, Ctr Sustainabil & Energy Technol, 259 Wenhua 1st Rd, Taoyuan 33302, Taiwan; Natl Univ Singapore, Dept Mech Engn, Singapore 117575, Singapore; Natl Univ Singapore, Chongqing Res Inst, Chongqing 401123, Peoples R China | Abdelaal, Mohamed/GLV-0541-2022; Walle, Kumlachew/G-6689-2017; Kotobuki, Masashi/AAB-2600-2022; Karuppiah, Chelladurai/H-7068-2019 | 36155900800; 55910716400; 57221629516; 59323356600; 9435063800; 55025126700 | kotobuki@mail.mcut.edu.tw;luli@nus.edu.sg; | NANO ENERGY | NANO ENERGY | 2211-2855 | 2211-3282 | 131 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2024 | 17.1 | 5.1 | 0.25 | 2025-05-07 | 2 | 2 | Mg batteries; Mg dendrites; Mg deposition/stripping; Nucleation; Surface diffusions | REVERSIBLE MAGNESIUM DEPOSITION; IN-SITU; ELECTROLYTE-SOLUTIONS; ELECTROCHEMICAL PERFORMANCE; PREFERENTIAL OXIDATION; CYCLE-LIFE; GROWTH; BATTERIES; STABILITY; ELECTRODEPOSITION | Mg batteries; Mg dendrites; Mg deposition/stripping; Nucleation; Surface diffusions | Coulomb efficiency; Dendrite formation; Energy density; Metal anodes; Metal deposition; Mg batteries; Mg dendrite; Mg deposition; Mg deposition/stripping; Mg metals | English | 2024 | 2024-12-01 | 10.1016/j.nanoen.2024.110292 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Assessing respiratory airflow unsteadiness under different tidal respiratory frequencies using large eddy simulation method | Unsteady respiratory airflow characteristics play a crucial role in understanding the deposition of toxic particles and inhaled aerosol drugs in the human respiratory tract. Considering the variations in respiratory flow rate and glottis motion under different respiratory frequencies, these respiratory airflow characteristics are studied by large-eddy simulations, including pressure field, power loss, modal spatial patterns, and vortex structures. Firstly, the results reveal that varying respiratory frequencies significantly affect airflow unsteadiness, turbulent evolution, and vortex structure dissipation, as they increase the complexity and butterfly effect introduced by the turbulent disturbance. Secondly, the pressure drops and flow rate at the glottis also conform to a power-law relationship considering the respiratory physiological characteristics, especially under low respiratory frequencies. Glottis motion plays different roles in energy consumption during inspiration and expiration, and its magnitude can be predicted using a polynomial function based on glottis area and respiratory flowrate under different respiratory frequencies. Finally, modal decomposition can be effectively applied to the study of respiratory flow characteristics, but we recommend separately studying the inspiration and expiration. The spatial distribution of the dominant mode characterizes the majority of respiratory flow characteristics and are influenced by respiratory frequency. Spectral entropy results indicate that glottis motion and slow breathing both delay the transitions in the upper respiratory tract during inspiration and expiration. These results confirm that the respiratory physiology characteristics under different respiratory frequencies have a significant impact on the unsteady respiratory airflow characteristics and warrant further study. © 2024 | Jing, Hao; Ge, Haiwen; Tang, Hui; Weng, Wenguo; Choi, Sanghun; Wang, Chenglei; Wang, Li; Cui, Xinguang | School of Aerospace Engineering, Huazhong University of Science and Technology, Wuhan, 430074, China; Research Center for Intelligent Supercomputing, Zhejiang Laboratory, Hangzhou, 311101, China; Department of Mechanical Engineering, The Hong Kong Polytechnic University, 999077, Hong Kong; Institute of Public Safety Research, Department of Engineering Physics, Tsinghua University, Beijing, 100084, China; School of Mechanical Engineering, Kyungpook National University, Daegu, 41566, South Korea; Department of Mechanical Engineering, The Hong Kong Polytechnic University, 999077, Hong Kong; School of Environmental Science and Engineering, Tianjin University, Tianjin, 300072, China; School of Aerospace Engineering, Huazhong University of Science and Technology, Wuhan, 430074, China | 57222810520; 14421143900; 57216712371; 21733887300; 55847101000; 57021081700; 57196340157; 50261346800 | xinguang_cui@mail.hust.edu.cn; | Computers in Biology and Medicine | COMPUT BIOL MED | 0010-4825 | 1879-0534 | 179 | SCIE | COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;ENGINEERING, BIOMEDICAL;MATHEMATICAL & COMPUTATIONAL BIOLOGY;BIOLOGY | 2024 | 6.3 | 5.2 | 0.39 | 2025-05-07 | 1 | Glottis motion; Modal decomposition; Respiratory frequency; Turbulent evolution; Unsteady respiratory airflow | Computer Simulation; Glottis; Humans; Models, Biological; Pulmonary Ventilation; Respiratory Rate; Air; Energy utilization; Physiology; Vortex flow; Airflow characteristics; Flow characteristic; Glottis motion; Modal decomposition; Respiratory airflow; Respiratory flow; Respiratory frequency; Turbulent evolution; Unsteady respiratory airflow; Vortex structures; air temperature; Article; atmospheric pressure; breathing rate; energy consumption; energy expenditure; expiratory flow rate; flow rate; glottis; human; inhalation; model; mouth cavity; respiratory airflow; respiratory function; tidal volume; vocal cord; biological model; breathing rate; computer simulation; lung ventilation; physiology; Large eddy simulation | English | Final | 2024 | 10.1016/j.compbiomed.2024.108834 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | Consensus Statement: Postoperative Management After Balloon Dilation of the Eustachian Tube | Objectives. Balloon dilation of the Eustachian tube (BDET) is widely recognized as a minimally invasive treatment for obstructive Eustachian tube dysfunction (ETD). We employed a Delphi consensus methodology to develop recommendations for the clinical management of BDET in cases of obstructive ETD. Methods. A Delphi panel consisting of 26 expert physicians specializing in otology participated in two rounds of anonymous, iterative questionnaires. Consensus was defined as agreement from >= 70% of the panelists on a recommendation, while disagreement was defined as <70% agreement.The responses from the Delphi study were analyzed using both the content validity ratio and Kendall's coefficient of concordance. Results. The panel finally evaluated 26 topics, reaching agreement on 9 and failing to reach consensus on 17 after two rounds. While consensus was not achieved regarding the postoperative follow-up period, a duration of 12 months was most commonly adopted.TheValsalva maneuver and questionnaire responses were identified as the most agreed-upon postoperative assessment tools following BDET. Conclusion. Consensus was reached on several recommendations for managing BEDT in obstructive ETD. This agreement will guide future research aimed at defining standard postoperative management for BEDT. | Kwak, Min Young; Lee, Ho Yun; Kong, Soo-Keun; Moon, In Seok; Kim, Bong Jik; Suh, Myung-Whan; Jung, Jae Yun; Park, Hong Ju; Lee, Kyu-Yup; Cho, Hyong-Ho; Ikeda, Ryoukichi; Son, Jae-Jin; Lee, Chi-Kyou | Hallym Univ, Dongtan Sacred Heart Hosp, Dept Otorhinolaryngol Head & Neck Surg, Coll Med, Hwaseong, South Korea; Ewha Womans Univ, Dept Otorhinolaryngol Head & Neck Surg, Coll Med, Seoul, South Korea; Pusan Natl Univ, Dept Otorhinolaryngol Head & Neck Surg, Coll Med, Busan, South Korea; Yonsei Univ, Coll Med, Severance Hosp, Dept Otorhinolaryngol, Seoul, South Korea; Chungnam Natl Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Daejeon, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Seoul, South Korea; Dankook Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Cheonan, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Otorhinolaryngol & Head & Neck Surg, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Daegu, South Korea; Chonnam Natl Univ, Med Sch, Dept Otolaryngol Head & Neck Surg, Gwangju, South Korea; Chonnam Natl Univ Hosp, Gwangju, South Korea; Iwate Med Univ, Dept Otolaryngol Head & Ned Surg, Morioka, Iwate, Japan; Seoul Natl Univ, Coll Med, Bundang Hosp, Dept Otorhinolaryrgol Head & Neck Surg, Seongnam, South Korea; Soonchunhyang Univ, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, 59 Daesagwan Ro, Seoul 04401, South Korea | ; KIM, JONG-IL/D-1019-2011; Suh, Myung-Whan/AAZ-9615-2020; Song, Jae-Jin/E-4633-2017; Ikeda, Ryoukichi/ABI-3240-2020 | 57205166252; 57189579843; 24831909300; 55953868500; 36811908900; 7103253889; 55682282900; 57213039619; 22135779500; 8363917300; 26537533000; 56294178300; 10143369300 | kwakmy@dongtan.ac.kr;hylee@ewha.ac.kr;ismoon@snubh.org;suhmw@snu.ac.kr;jyjung@pusan.ac.kr;hjpark@snu.ac.kr;kyylee@knu.ac.kr;hhjeon@snubh.org;ikedar@iwak.ac.jp;jjson@snubh.org;cklee@snubh.org;drqlee@hanmail.net; | CLINICAL AND EXPERIMENTAL OTORHINOLARYNGOLOGY | CLIN EXP OTORHINOLAR | 1976-8710 | 2005-0720 | 17 | 4 | SCIE | OTORHINOLARYNGOLOGY | 2024 | 3.4 | 5.2 | 0 | 2025-05-07 | 0 | 0 | Delphi; Eustachian Tube; Balloon Dilation; Obstructive | OTITIS-MEDIA; TUBOPLASTY; DYSFUNCTION | Balloon Dilation; Delphi; Eustachian Tube; Obstructive | English | 2024 | 2024-11 | 10.21053/ceo.2024.00121 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | ECC-PDGPP: ECC-Based Parallel Dependency RFID-Grouping-Proof Protocol Using Zero-Knowledge Property in the Internet of Things Environment | Radio Frequency Identification (RFID) promotes the fundamental tracking procedure of the Internet of Things (IoT) network due to its autonomous data collection as well as transfer incurring low costs. To overcome the insecure exchange of tracking data and to prevent unauthorized access, parallel dependency RFID grouping-proof protocol is applied by the reader to authenticate tags simultaneously. However, conventional grouping-proof authentication schemes are not sufficient for the memory constraint RFID tags due to the recurrent utilization of a 128-bit PRNG (Pseudo Random Number Generator) function. Alternatively, the existing parallel-dependency grouping-proof schemes are not able to overcome numerous limitations regarding session establishment, efficient key management, and multicast message communication within the specified group. In this research, a lightweight, secure, and efficient communication protocol is proposed to overcome the aforementioned limitations using Elliptic Curve Cryptography (ECC) and Zero-Knowledge property to establish a session key among the participated tags, reader, and remote server. The proposed scheme can work in offline mode. The proposed ECC-based parallel dependency grouping-proof scheme is referred to as ECC-PDGPP which abides by the rules of the EPC class-1 gen-2 (C1 G2) standard of RFID tags. Finally, the proposed protocol is analyzed using a formal random oracle model and simulated using a well-known AVISPA simulation tool that shows the proposed scheme is well protected against all potential security threats. | Majumder, Suman; Ray, Sangram; Sadhukhan, Dipanwita; Dasgupta, Mou; Das, Ashok Kumar; Park, Youngho | Natl Inst Technol Sikkim, Dept Comp Sci & Engn, Ravangla, India; Siksha O Anusandhan Deemed Univ, Dept Comp Sci, Bhubaneswar 751030, India; Natl Inst Technol Raipur, Dept Comp Applicat, Raipur, India; Int Inst Informat Technol, Ctr Secur Theory & Algorithm Res, Hyderabad, India; Kyungpook Natl Univ, Sch Elect Engn, Sch Elect & Elect Engn, Daegu, South Korea | Das, Ashok Kumar/U-2790-2019; MAJUMDER, SUMAN/JBJ-4837-2023; Ray, Sangram/AAN-4668-2020; Sadhukhan, Dipanwita/AFZ-5167-2022 | 57220586010; 55028181000; 57212555532; 36069016500; 55450732800; 56962990300 | suman.majumder3014@gmail.com;sangram.ism@gmail.com;dipanwitasadhukhan2012@gmail.com;elle.est.mou@gmail.com;iitkgp.akdas@gmail.com;parkyh@knu.ac.kr; | IEEE OPEN JOURNAL OF THE COMPUTER SOCIETY | IEEE OPEN J COMP SOC | 2644-1268 | 5 | ESCI | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;COMPUTER SCIENCE, THEORY & METHODS;ENGINEERING, ELECTRICAL & ELECTRONIC;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 8.2 | 5.2 | 1.06 | 2025-04-16 | 1 | 2 | Elliptic curve discrete logarithm problem (ECDLP); Internet of Things (IoT); pseudo random number generator (PRNG); radio frequency identification (RFID) | AUTHENTICATION PROTOCOL; SECURE; SAFETY | Elliptic curve discrete logarithm problem (ECDLP); Internet of Things (IoT); pseudo random number generator (PRNG); radio frequency identification (RFID) | Geometry; Internet of things; Internet protocols; Network security; Number theory; Public key cryptography; Radio frequency identification (RFID); Radio waves; Random number generation; Curve cryptography; Elliptic curve; Elliptic curve cryptography; Elliptic curve discrete logarithm problem; Elliptic curve discrete logarithm problems; Internet of thing; Pseudo random number generator; Pseudorandom number generators; Radio frequency identification; Radio-frequency-identification; Radiofrequency identification tags; Security; Authentication | English | 2024 | 2024 | 10.1109/ojcs.2024.3406142 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Emergence of Salmonella Infantis carrying the pESI megaplasmid in commercial farms of five major integrated broiler operations in Korea | Considering Salmonella transmission occurs through several routes in integrated broiler operations, control of nontyphoidal Salmonella in commercial farms is essential. This study aimed to compare the distribution of persistent Salmonella serovars in environments and dead chickens between 5 major integrated broiler operations in Korea. The prevalence of Salmonella -positive farms in dust prior to placement by operations was 0 to 25%, but the prevalence in dust and feces at the time of depletion was increased to 16.7 to 41.7% and 16.7 to 66.7%, respectively. Moreover, the prevalence of farms with Salmonella in chickens that died within 1 week old and at 4 to 5 weeks old ranged from 8.3 to 58.3% and 16.7 to 41.7%, respectively. The prevalence of Salmonella enterica serovar Infantis-positive farms in dust prior to placement and in chickens that died within 1 week old was 5.2 and 3.4%, respectively, but the prevalence in dust and feces at the time of depletion and in chickens that died at 4 to 5 weeks old was significantly increased to 27.6, 41.4, and 20.7%, respectively (P < 0.05). Interestingly, the plasmid of emerging S. Infantis (pESI) was only identified in S. Infantis, and the prevalence of multidrug-resistance was significantly higher in pESI-positive S. Infantis (99.2%) than in pESI-negative S. Infantis (6.7%) (P < 0.05). The distribution of pulsotypes between pESI-positive and pESI-negative S. Infantis were varied, but a majority of S. Infantis were clustered only 2 pulsotypes. Moreover, pESI-positive S. Infantis harbored more virulence factors than pESI-negative S. Infantis. This study is the first report on characteristics of S. Infantis carrying the pESI plasmid in commercial broiler farms in Korea. | Kim, Min Beom; Jung, Hye-Ri; Lee, Young Ju | Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Vet Biomed Sci, Daegu 41566, South Korea | 58891566600; 57265190900; 56612134500 | youngju@knu.ac.kr; | POULTRY SCIENCE | POULTRY SCI | 0032-5791 | 1525-3171 | 103 | 4 | SCIE | AGRICULTURE, DAIRY & ANIMAL SCIENCE | 2024 | 4.2 | 5.2 | 6.43 | 2025-05-07 | 9 | 8 | Salmonella Infantis; pESI plasmid; broiler; emerging pathogen | ENTERICA SEROVARS; VIRULENCE GENES; CHICKEN; CONTAMINATION; POULTRY; STRAINS; EGG; PATHOGENICITY; TYPHIMURIUM; PENETRATION | broiler; emerging pathogen; pESI plasmid; Salmonella Infantis | Animals; Anti-Bacterial Agents; Chickens; Dust; Farms; Republic of Korea; Salmonella; Salmonella enterica; Salmonella enterica subsp. enterica; Salmonella Infections, Animal; antiinfective agent; agricultural worker; animal; animal salmonellosis; dust; Gallus gallus; genetics; Salmonella; Salmonella enterica; Salmonella enterica subsp. enterica; South Korea | English | 2024 | 2024-04 | 10.1016/j.psj.2024.103516 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Energy-saving potential estimation of retrofitting aged buildings considering external wall insulation degradation | This study presents the potential for improving energy performance by considering thermal performance degradation due to the aging of building envelopes. The U-value is a critical parameter for simulating a building's energy performance evaluation. However, because of the difficulty of in-situ measurements, many cases involve using standard or normative values for assessment. Nevertheless, considering the degradation of the external wall's insulation performance due to aging is crucial. We measured the thermal transmittance of external walls in 62 aged buildings constructed in various periods and quantitatively derived the degree of insulation performance degradation by comparing it with the legal standards at the time of construction. Moreover, to analyze the problems caused by neglecting the U-value deterioration in evaluating the energysaving potential through retrofitting, a case study was conducted on 70 aged buildings where actual retrofit projects were implemented. We compared the cases by applying both legal thermal transmittance standards and corrected values based on actual measurements to the sites' preretrofit energy simulation models. The measurements showed that the aged buildings had an average insulation performance degradation of 49.69 % compared to the legal standards at the time of approval. Simply using the legal standard for the external wall's thermal transmittance underestimated the energy savings by 16.73 %. Furthermore, the study confirmed that correcting the U-value based on actual measurement data is essential for accurately evaluating the retrofit effect on aged buildings. | Yun, Woo-Seung; Ryu, Wontaek; Lee, Dongrim; Seo, Hyuncheol | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Convergence Inst Construction Environm & Energy En, Daegu 41566, South Korea | ; Seo, Hyuncheol/ABC-5117-2020 | 57221104908; 58203608600; 59182497000; 56083741500 | bmqwe011@knu.ac.kr;dbdnjsxor97@knu.ac.kr;knuicon@knu.ac.kr;charles@knu.ac.kr; | JOURNAL OF BUILDING ENGINEERING | J BUILD ENG | 2352-7102 | 94 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2024 | 7.4 | 5.2 | 1.52 | 2025-05-07 | 7 | 7 | U-value; Retrofit; Energy saving potential; Insulation degradation | PERFORMANCE | Energy saving potential; Insulation degradation; Retrofit; U-value | Deterioration; Energy efficiency; Thermal insulation; Walls (structural partitions); Energy savings potential; External wall insulations; External walls; Insulation degradation; Insulation performance; Legal standards; Performance degradation; Retrofit; Thermal transmittance; U values; Retrofitting | English | 2024 | 2024-10-01 | 10.1016/j.jobe.2024.110022 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enhancing wildfire mapping accuracy using mono-temporal Sentinel-2 data: A novel approach through qualitative and quantitative feature selection with explainable AI | Accurate wildfire severity mapping (WSM) is crucial in environmental damage assessment and recovery strategies. Machine learning (ML) and remote sensing technologies are extensively integrated and employed as powerful tools for WSM. However, the intricate nature of ML algorithms often leads to 'black box' systems, obscuring the decision-making process and significantly limiting stakeholders' ability to comprehend the basis of predictions. This opacity hinders efforts to enhance performance and risks exacerbating overfitting. This present study proposes an innovative WSM approach that incorporates qualitative and quantitative feature selection techniques within the Explainable AI (XAI) framework. The methodology aims to enhance the precision of WSM and provide insights into the factors contributing to model decisions, thereby increasing the interpretability of predictions and streamlining models to improve performance. To achieve this objective, we employed the SHapley Additive exPlanations (SHAP)-Forward Stepwise Selection (FSS) method to demonstrate its efficacy in elucidating the qualitative and quantitative impacts of predictors on ML algorithm performance, accuracy, and interpretability designed for WSM. Utilizing post-fire imagery from Sentinel-2 (S2), we analyzed ten bands to generate 225 unique spectral indices utilizing five different calculations: normalized, algebraic sum, difference, ratio, and product forms. Combined with the original S2 bands, this resulted in 235 potential predictors for ML classifications. A random forest model was subsequently developed using these predictors and optimized through extensive hyperparameter tuning, achieving an overall accuracy (OA) of 0.917 and a Kappa statistic of 0.896. The most influential predictors were identified using SHAP values, with an FSS process narrowing them down to the 12 most critical for effective WSM, as evidenced by stabilized OA and Kappa values (0.904 and 0.881, respectively). Further validation using a ninefold spatial cross-validation technique demonstrated the method's consistent performance across different data partitions, with OA values ranging from 0.705 to 0.894 and Kappa values from 0.607 to 0.867. By providing a more accurate and comprehensible XAI-based method for WSM, this research contributes to the broader field of environmental monitoring and disaster response, underscoring the potential of integrated qualitative and quantitative analysis to enhance ML models' capabilities. | Van, Linh Nguyen; Tran, Vinh Ngoc; V.

| ○ | ○ | Article | Estimated economic costs of dental implants among older South Korean adults, 2015-2018 | ObjectiveDental implants are a considerable financial burden for elderly people and their caregivers. This study aimed to calculate the estimated economic costs of dental implants on the Korean older population.Materials and MethodsThe economic costs of dental implants for adults aged 75 years and older were estimated from a societal perspective, considering both direct and indirect expenditures. We used data from the Korean National Health Insurance Service for the period 2015-2018 to estimate the medical costs. Noninsured medical costs were estimated from research on medical expenses by the National Health Insurance Review and Assessment Service. Indirect costs related to transportation fees and time loss were obtained. The Cochran Armitage trend test was performed to examine the trend of the economic burden of dental implants.ResultsThe estimated economic costs showed from 2015 to 2018 (total costs: $26.54-55.66 million, total costs after discount: $17.11-39.56 million). Direct costs, including insured and noninsured medical costs, represented from $25.81 to $47.03 million. Indirect costs, including transportation and time costs, ranged from $0.73 to $1.63 million. The impact of the total dental implant costs was 0.0018%-0.0034% of the Korean annual gross domestic product and 1.03%-1.59% of the annual total costs of dental care benefits.ConclusionsThe estimated economic burden of dental implants significantly increased from 2015 to 2018 in older South Korean adults. These results will provide a foundation and guidance for further health economic studies on the burden of dental implants in the elderly population. | Go, Hyeonjeong; Ahn, Jeonghoon; Ahn, Song Vogue; Shin, Hosung; Amano, Atsuo; Choi, Youn-Hee | Kyungpook Natl Univ, Sch Dent, Dept Prevent Dent, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul, South Korea; Wonkwang Univ, Sch Dent, Dept Social & Human Dent, Iksan, North Jula, South Korea; Osaka Univ, Grad Sch Dent, Dept Prevent Dent, Suita, Osaka, Japan; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu, South Korea | ; Ahn, Song/AAK-2900-2021; Ahn, Jeonghoon/CAA-1956-2022 | 57196085646; 8855402200; 47360986600; 7404012269; 7101649822; 7404777239 | cyh1001@knu.ac.kr; | CLINICAL ORAL IMPLANTS RESEARCH | CLIN ORAL IMPLAN RES | 0905-7161 | 1600-0501 | 35 | 12 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE;ENGINEERING, BIOMEDICAL | 2024 | 5.3 | 5.2 | 0 | 2025-05-07 | 0 | 0 | dental implants; economic costs; economic burden; Korean National Health Service Insurance; older adults | dental implants; economic burden; economic costs; Korean National Health Service Insurance; older adults | Aged; Aged, 80 and over; Cost of Illness; Dental Implants; Female; Health Care Costs; Health Expenditures; Humans; Male; Republic of Korea; aged; cost of illness; economics; female; health care cost; human; male; South Korea; tooth implant; very elderly | English | 2024 | 2024-12 | 10.1111/clr.14343 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
