| ○ | ○ | Article | Predicting permanent strain accumulation of unbound aggregates using machine learning algorithms | The objective of this study is to propose a machine learning-based framework for predicting the permanent strain accumulation of unbound aggregates. To develop the machine learning-based framework, material properties of 15 crushed aggregates determined at two different gradations are combined with the applied stress states on aggregate specimens during repeated load triaxial testing by considering the aggregate shear strength characteristics. Three single machine learning algorithms (K-nearest neighbor, neural network, and decision tree) and two ensemble learning algorithms (random forest and extreme gradient boosting) are used in this study. Based on the dataset obtained from 90 permanent deformation tests, hyperparameters, which are used to control the learning process, are optimized. The numerical results demonstrate that all five of the tuned machine learning models exhibit good generalization capacity and performance with the coefficient of determination exceeding 0.99. Among the five models, the extreme gradient boosting model outperforms the others, accurately predicting permanent strain accumulation even for load cycles of 10,000. The contributions of individual input features to the performance of each learning model depend on the dataset. The strength characteristics and the applied deviatoric stress are the two most important features. Therefore, the machine learning-based framework introduced in this study may be effectively used for predicting the permanent strain accumulation of unbound aggregate layer. | Won, Jongmuk; Tutumluer, Erol; Byun, Yong-Hoon | Univ Ulsan, Dept Civil & Environm Engn, Daehak Ro 93, Ulsan 680749, South Korea; Univ Illinois, Dept Civil & Environm Engn, 205 North Mathews Ave, Urbana, IL 61801 USA; Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, 80 Daehak Ro, Daegu 41566, South Korea | Tutumluer, Erol/O-2650-2019; Byun, Yong-Hoon/JKI-8441-2023 | 53878877200; 6603812780; 42761048000 | yhbyun@knu.ac.kr; | TRANSPORTATION GEOTECHNICS | TRANSP GEOTECH | 2214-3912 | 42 | SCIE | ENGINEERING, CIVIL;ENGINEERING, GEOLOGICAL | 2023 | 4.9 | 10.7 | 1.64 | 2025-06-25 | 14 | 14 | Aggregate; Feature importance; Machine learning; Permanent strain; Predictive model | RESILIENT MODULUS; SUBBASE MATERIALS | Aggregate; Feature importance; Machine learning; Permanent strain; Predictive model | aggregate; algorithm; fracture; machine learning; modeling; shear strength; strain | English | 2023 | 2023-09 | 10.1016/j.trgeo.2023.101060 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Global lineage evolution pattern of sars-cov-2 in Africa, America, Europe, and Asia: A comparative analysis of variant clusters and their relevance across continents | Objective: The objective of this study is to provide a comparative analysis of variant clusters and their relevance across Africa, America, Europe, and Asia, in order to understand the evolutionary patterns of the virus across different regions and to inform the development of targeted interventions and genomic surveillance eforts. Methods: The study analyzed the global lineage evolution pattern of 74, 075 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes from 32 countries across four continents, focusing on variant clusters and their relevance across regions. Variants were weighted according to their hierarchical level. The correlation between variants was visualized through Dimensionality reduction analysis and Pairwise Pearson's correlation. We presented a reconstructed phylogenetic tree based on correlation analysis and variant weights. Results: The analysis revealed that each continent had distinct variant clusters and different evolutionary patterns. The Americas had two clustered variants before lineage divergence and a downstream confluence lineage, Europe had bifurcation into two global lineages with an early occurrence of certain cluster while Asia had a downstream confluence of two large lineages diverging by two distinct clusters. Based on the cluster patterns of shared variants of the SARS-CoV-2 virus, Africa demonstrated a relatively clear distinction among three distinct regions. Conclusions: The study provides insights into the evolutionary patterns of SARS-CoV-2 and highlights the importance of international collaboration in tracking and responding to emerging variants. The study found that the global pandemic was driven by Omicron variants that evolved with significant differences between countries and regions, and with different patterns across continents. | Hyug Choi, June; Sook Jun, Mee; Yong Jeon, Jeong; Kim, Hae-Suk; Kyung Kim, Yu; Ho Jeon, Chang; Hwan Choi, Seock; Sun Kim, Dong; Han, Man-Hoon; Won Oh, Ji | Kyungpook Natl Univ, Sch Med, Dept Anat, FOUR KNU Convergence Educ Program Biomed Sci Creat, Daegu, South Korea; Chungbuk Natl Univ, Dept Internal Med, Cheongju, South Korea; Yonsei Univ Ind Fdn, Seoul, South Korea; Absolute DNA Inc, Daegu, South Korea; Theragen Bio Co Ltd, Seongnam Si, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea; Catholic Univ, Daegu Sch Med, Dept Lab Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Biomed Res Inst, Sch Med,Dept Urol, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Biomed Res Inst, Sch Med,Dept Pathol, Daegu, South Korea; Yonsei Univ, Dept Anat, Brain Korea PLUS Project Med Sci 21, Coll Med, Seoul, South Korea; Yonsei Univ, Dept Anat, Coll Med, Seoul, South Korea | ; Oh, Ji/AAZ-3153-2020 | 57195986324; 7006544857; 58786642000; 58785955300; 9237571900; 35082040600; 9742645500; 57125070500; 57194067936; 36093206200 | one-many@hanmail.net;g1@yuhs.ac; | JOURNAL OF TRANSLATIONAL INTERNAL MEDICINE | J TRANSL INTERN MED | 2450-131X | 2224-4018 | 11 | 4 | SCIE | MEDICINE, GENERAL & INTERNAL | 2023 | 4.7 | 10.8 | 0.65 | 2025-06-25 | 4 | 4 | lineage evolution; SARS-CoV-2; variant | lineage evolution; SARS-CoV-2; variant | Africa; Article; Asia; cladistics; clinical practice; comparative study; controlled study; dimensionality reduction; Europe; gene mutation; nonhuman; pandemic; phylogenetic tree; phylogeny; public health; SARS-CoV-2 Omicron; Severe acute respiratory syndrome coronavirus 2; viral evolution; virus genome; Western Hemisphere | English | 2023 | 2023-12-20 | 10.2478/jtim-2023-0118 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | 2D ultrathin ZnIn2S4 nanosheets anchored on octahedral TiO2/Ti3C2 Z-scheme heterostructure for enhanced photocatalytic CO2 reduction | The low carbon dioxide (CO2) conversion efficiency of semiconductor heterojunction-based photocatalysts is a lingering issue in the field of solar energy-driven catalysis. In this study, sandwich-like hierarchical hetero-structures of two-dimensional (2D) ultrathin ZnIn2S4 nanosheets and octahedral titanium dioxide (TiO2) nano-particles were grown in situ on Ti3C2 MXene via a hydrothermal method. Significantly, the ZnIn2S4@TiO2/Ti3C2 ternary heterostructure shows better CO2 reduction activity and the optimal catalyst has carbon monoxide (CO) and methane (CH4) production rates of 59.8 and 23.44 & mu;mol g 1, respectively, within 8 h of simulated solar light illumination, which was greater than that pristine ZnIn2S4. These ultrathin ZnIn2S4 nanosheets and TiO2/Ti3C2 Schottky-junctions assisted the heterostructures to reduce photogenerated electron-hole recombination and in-crease photogenerated charge-transfer and separation in a Z-scheme pathway. ZnIn2S4@TiO2/Ti3C2 hetero-structure photocatalysts have superior photocatalytic CO2 conversion and good stability compared to pure ZnIn2S4. Thus, the suggested approach is to design a highly-efficient photocatalyst for environmental remediation. | Devarayapalli, Kamakshaiah Charyulu; Kim, Bolam; Manchuri, Amaranadha Reddy; Lim, Youngsu; Kim, Gyuhyeon; Lee, Dae Sung | Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Core Res Inst, Res Inst Environm Sci & Technol, Daegu 41566, South Korea | ; Manchuri, Amaranadha Reddy/J-3982-2016 | 15069351300; 57208922438; 58343647900; 57207112603; 58099353000; 55568524907 | daesung@knu.ac.kr; | APPLIED SURFACE SCIENCE | APPL SURF SCI | 0169-4332 | 1873-5584 | 636 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 6.3 | 10.9 | 3.71 | 2025-06-25 | 31 | 30 | CO2 reduction; TiO2; MXene; Z-scheme | HYDROGEN EVOLUTION; TIO2 NANOCRYSTALS; TEMPERATURE; FABRICATION; WATER | CO<sub>2</sub> reduction; MXene; TiO<sub>2</sub>; Z-scheme; ZnIn<sub>2</sub>S<sub>4</sub> | Carbon dioxide; Carbon monoxide; Catalyst activity; Charge transfer; Conversion efficiency; Heterojunctions; Nanosheets; Solar energy; Solar light; TiO2 nanoparticles; Zinc compounds; % reductions; Carbon monoxide2 reduction; Energy-driven; Hydrothermal methods; Mxene; Photo-catalytic; Semiconductor heterojunctions; Two-dimensional; Ultra-thin; Z-scheme; Titanium dioxide | English | 2023 | 2023-11-01 | 10.1016/j.apsusc.2023.157865 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bimetallic Cu-Ni core-shell nanoparticles anchored N-doped reduced graphene oxide as a high-performance bifunctional electrocatalyst for alkaline water splitting | Water electrolysis is regarded as the most promising method for developing sustainable energy technologies. However, low-cost bifunctional electrocatalysts with high efficacy and long-term stability are required to make this method economically viable. Core-shell nanoparticles, which comprise a thin layer of a catalytically active shell surrounding a subsurface core, have recently emerged as cutting-edge electrocatalysts for effective water electrolysis. Herein, we systematically fabricated distinct bimetallic Cu-Ni particles by tuning the Cu:Ni ratios, and then anchored them to an N-doped reduced graphene oxide (NRG) backbone for alkaline water splitting. A Cu:Ni molar ratio of 1:1 was determined to be optimal for forming an effective core-shell configuration, affording favorable adsorption energies toward reactants. The Cu-Ni(1:1) core-shell nanoparticles anchored NRG, termed Cu-Ni(1:1)@NRG, displayed excellent performance toward the H2 evolution reaction (HER) and oxygen evolution reaction (OER), with overpotentials at 10 mA cm-2 of 107 and 310 mV, respectively, versus a reversible hydrogen electrode (RHE). This current density (10 mA cm- 2) was attained at a low cell voltage of 1.64 V when Cu-Ni(1:1)@NRG was used as the bifunctional electrocatalyst for alkaline water electrolysis. Furthermore, the Cu-Ni(1:1)@NRG electrocatalyst exhibited outstanding long-term stability in prolonged elec-trocatalytic studies at a constant current density. | Lee, Dong-Eun; Moru, Satyanarayana; Reddy, Kasala Prabhakar; Jo, Wan-Kuen; Tonda, Surendar | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; VIT AP Univ, Sch Adv Sci, Amaravati 522237, Andhra Pradesh, India; Univ South Carolina, Dept Chem & Biochem, 631 Sumter St, Columbia, SC 29208 USA | ; Moru, Satyanarayana/AAF-3189-2021; Jo, Wan/AAO-5329-2020; MORU, SATYANARAYANA/AAF-3189-2021; Tonda, Surendar/AAO-3358-2020; Kasala, Prabhakar Reddy/AFV-7189-2022 | 56605563300; 58562229700; 58156514000; 7103322277; 56114866900 | satyanarayana.moru@vitap.ac.in;surendart@knu.ac.kr; | APPLIED SURFACE SCIENCE | APPL SURF SCI | 0169-4332 | 1873-5584 | 622 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 6.3 | 10.9 | 1.48 | 2025-06-25 | 11 | 12 | Cu-Ni bimetallic catalyst; N-doped graphene; Core-shell configuration; Electrocatalysis; Overall water splitting | AT-NI; EFFICIENT; NANOSHEETS; NITRIDE | Core–shell configuration; Cu–Ni bimetallic catalyst; Electrocatalysis; N-doped graphene; Overall water splitting | Core shell nanoparticles; Costs; Doping (additives); Electrocatalysis; Electrocatalysts; Electrolysis; Molar ratio; Shells (structures); Bimetallic catalysts; Core shell; Core-shell nanoparticles; Core–shell configuration; Cu–ni bimetallic catalyst; N-doped; N-doped graphene; Overall water splitting; Reduced graphene oxides; Water splitting; Graphene | English | 2023 | 2023-06-15 | 10.1016/j.apsusc.2023.156928 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Coupled Inductor Based Voltage Balancing in Dual-Output CLL Resonant Converter for Bipolar DC Distribution System | Bipolar dc distribution systems face imbalances in voltages when unbalanced loads are connected at the outputs. To address imbalances in bipolar voltage levels, dedicated voltage balancers are required. However, they add extra active and/or passive components; including, magnetics, capacitors, etc. This increases the cost, reduces the conversion efficiency, and power density of dual-output converters. Therefore, to tackle the imbalances in output voltages without adding any extra active and/or passive components, this article presents coupled inductor (CI) based voltage balancing in dual-output CLL resonant converter. The main features of the proposed method are as follows: since CI is the result of already present resonant inductors of CLL tank circuit, therefore, it does not require extra magnetic components to balance the output voltages; with no additional components, it does not increase the magnetic volume, component count, cost, and complexity of the converter; due to the direct coupling, a half of circuit inductances are integrated to achieve the respective resonant inductance of the tank circuit; and it can also avoid complex control schemes applied to voltage balancing. Besides, with the proposed CI, the CLL converter maintains all of its good features including; zero-voltage and zero-current-switching (ZVZCS). The detailed analysis of the proposed CI with different load conditions is discussed. Moreover, LLC or Type-12 resonant tank circuit is presented to validate ZVZCS operation in the reverse power flow condition. To verify the effectiveness of the proposed CI based voltage balancing, a 3.6-kW hardware prototype has been built and tested. | Ahmad, Ubaid; Cha, Honnyong | Kyungpook Natl Univ, Daegu 41566, South Korea | Ahmad, Ubaid/IXM-9731-2023 | 58257165200; 24450248400 | engrubaid0456@gmail.com;chahonny@knu.ac.kr; | IEEE TRANSACTIONS ON POWER ELECTRONICS | IEEE T POWER ELECTR | 0885-8993 | 1941-0107 | 38 | 1 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2023 | 6.6 | 10.9 | 1.71 | 2025-06-25 | 11 | 14 | Bipolar dc distribution system; coupled inductor (CI); dual-output CLL resonant converter; voltage balancing | Bipolar dc distribution system; Coupled inductor; Dual-output CLL resonant converter; Voltage balancing | Electric inductors; Electric network analysis; Inductance; Power converters; Resonant circuits; Tanks (containers); Zero current switching; Zero voltage switching; Bipolar dc distribution system; Coupled inductor; DC distribution system; Dual outputs; Dual-output CLL resonant converter; Output voltages; Resonant converters; Tank circuits; Unbalanced loads; Voltage balancing; Electric load flow | English | 2023 | 2023-01 | 10.1109/tpel.2022.3204061 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficiency improvement of dye-sensitized solar cells using Cu,Co/TiO2 photoelectrodes doped by applying ultrasonic treatment | In this study, a dye-sensitized solar cell (DSSC) doped with Cu, Co was fabricated by simultaneously sonicating TiO2 and a trace amount of a transition metal precursor. The cavitation bubbles occurred during sonication resulted in defects on the surface of the TiO2 particles. As ultrasonic treatment was applied, doping was suc-cessfully performed even though Cu and Co were added in small amounts. The surface activation of TiO2 was confirmed by performing XPS, and the doping of Cu and Co was verified by employing TEM-EDS analysis. Fabricating doped TiO2 as a photoelectrode and analyzing it using UV-Vis spectroscopy demonstrated that the amount of dye adsorption was significantly increased. In addition, the reduction in electron transfer resistance was confirmed by applying EIS, and the factors contributing to efficiency improvement were investigated by calculating the chemical capacitance and recombination resistance. The maximum energy-conversion efficiency of the DSSCs fabricated by TiO2 which doped with Cu and Co by ultrasonic treatment was 4.16%, and that of the DSSCs fabricated with TiO2 not doped with a transition metal was measured at 2.93%. As above, TiO2 was doped with a transition metal using ultrasonic treatment, contributing to the improvement of the performance of the TiO2 photoelectrode. | Bae, Jae-hun; Jeon, Hwang-Ju; Cho, Sung-Ho; Cho, Yong-beom; Lee, Sung-Eun; Kim, Tae-Oh | Kumoh Natl Inst Technol, Dept Environm Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea; Kyungpook Natl Univ, Inst Evaluat Safety & Qual Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | Kim, Taeoh/F-4647-2012; Cho, Yong/F-4606-2014; Jeon, Hwangju/JDW-9035-2023 | 57435539800; 56328792200; 57435132600; 58125602200; 55890041600; 9335312200 | APPLIED SURFACE SCIENCE | APPL SURF SCI | 0169-4332 | 1873-5584 | 621 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 6.3 | 10.9 | 1.61 | 2025-06-25 | 12 | 13 | Ultrasonication; DSSC; Transition metal doping; TiO2 photoanode | COUNTER-ELECTRODE; TIO2; PERFORMANCE; PHOTOANODE; GRAPHENE; NANOWALL; XPS | DSSC; TiO<sub>2</sub> photoanode; Transition metal doping; Ultrasonication | Activation analysis; Cavitation; Cobalt; Copper; Dye-sensitized solar cells; Energy conversion efficiency; Fabrication; Trace elements; Cu/Co-AM; Dye- sensitized solar cells; Efficiency improvement; Photo-anodes; Photoelectrode; TiO2 photoanode; Trace amounts; Transition metal doping; Ultra-sonication; Ultrasonic treatments; Titanium dioxide | English | 2023 | 2023-06-01 | 10.1016/j.apsusc.2023.156823 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Face-to-face interfacial assembly of a hybrid NiAl-LDH@BiOIO3 photocatalyst for the effective solar-induced abatement of antibiotic and dye pollutants: Insights into surface engineering and S-scheme charge transfer | The development of hybrid catalysts with 2D/2D interfacial contact and step-scheme (S-scheme) charge transfer is crucial for photocatalysis because these catalysts potentially offer more efficient photoexcited charge separation and separated charge carriers with a stronger redox capability. In this study, we strategically developed a novel hybrid NiAl layered double hydroxide (LDH)@BiOIO3 (BOI) photocatalyst with effective S-scheme charge transfer for the efficient solar-induced abatement of aqueous antibiotic and dye pollutants. The in-situ growth of LDH sheets on BOI sheets yielded a hybrid 2D/2D LDH@BOI photocatalyst with favorable face-to-face interfacial contact, which provided a broader platform for photoinduced charge migration and minimizes charge recombination. Furthermore, the S-scheme charge transfer mechanism within the hybrid photocatalyst effectively promoted the separation of the photoinduced charge carriers and preserved their strong redox capability. These beneficial features, in combination with the large specific surface area and enhanced light-harvesting capability, were responsible for the exceptional photocatalytic performance of the optimized hybrid LDH@BOI photocatalyst in terms of the degradation and mineralization of sulfamethoxazole and Congo red dye. Notably, the proposed hybrid photocatalyst outperformed BOI and LDH individually and previously reported state-of-the-art photocatalysts while maintaining its stability over consecutive test cycles, highlighting it as a promising candidate for photocatalytic applications. | Lee, Dong-Eun; Kim, Dong Jin; Moru, Satyanarayana; Jo, Wan-Kuen; Tonda, Surendar | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro,Buk Gu, Daegu 41566, South Korea; VIT AP Univ, Sch Adv Sci, Amaravati 522237, Andhra Pradesh, India | Tonda, Surendar/AAO-3358-2020; Kim, Dong Jin/JMR-1090-2023; Jo, Wan/AAO-5329-2020; Moru, Satyanarayana/AAF-3189-2021; MORU, SATYANARAYANA/AAF-3189-2021 | 56605563300; 56984538100; 58562229700; 7103322277; 56114866900 | wkjo@knu.ac.kr;surendart@knu.ac.kr; | APPLIED SURFACE SCIENCE | APPL SURF SCI | 0169-4332 | 1873-5584 | 640 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 6.3 | 10.9 | 1.73 | 2025-06-25 | 14 | 15 | Layered double hydroxide; BiOIO 3; Face-to-face interfacial contact; 2D/2D configuration; S-scheme mechanism; Environmental remediation | CONGO-RED; AQUEOUS-SOLUTIONS; EFFICIENT; DEGRADATION; HETEROJUNCTION; BIOIO3; WATER; TIO2; CO2; SEPARATION | 2D/2D configuration; BiOIO<sub>3</sub>; environmental remediation; face-to-face interfacial contact; Layered double hydroxide; S-scheme mechanism | Antibiotics; Azo dyes; Binary alloys; Bismuth compounds; Catalysts; Charge carriers; 2d/2d configuration; Dye pollutants; Environmental remediation; Face to face; Face-to-face interfacial contact; Hybrid photocatalysts; Interfacial contact; Layered-double hydroxides; Ni-Al layered double hydroxides; Step-scheme mechanism; Charge transfer | English | 2023 | 2023-12-15 | 10.1016/j.apsusc.2023.158302 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Facet-induced charge transfer and photocatalytic performance of an S-scheme hybrid heterojunction composed of porous g-C3N4 nanosheets and WO3 nanorods with exposed high-energy (001) facets | Crystal facet engineering has been demonstrated to be a flexible technique that significantly improves photo -catalyst performance by promoting interfacial charge transfer and separation. In this study, we systematically coupled porous polymeric carbon nitride nanosheets (PCN) and WO3 nanorods with exposed (001) facets (WOAT) to fabricate a WOAT@PCN hybrid photocatalyst with improved photocatalytic properties. Importantly, the fabricated WOAT@PCN hybrid catalyst demonstrated significantly enhanced performance for the degradation of oxytetracycline and naproxen pollutants under visible light compared to PCN, WOAT, and WOST with different exposed facets. Furthermore, the hybrid catalyst demonstrated excellent stability and reusability across multiple test runs. The remarkable photodegradation performance of the hybrid catalyst is primarily attributable to the intrinsically high surface area and charge separation properties of the (001) facets of WOAT, enhanced visible light absorption, and S-scheme charge transfer at the interface, promoting photoexcited charge separation and enhancing the redox capabilities of the separated photoexcited electrons and holes. In addition, total organic carbon (TOC) analysis confirmed the efficacy of mineralization, while liquid chromatography/tandem mass spectrometry (LC/MS/MS) studies revealed the potential degradation pathways of sample pollutants. This study elucidates the systematic design of hybrid catalysts using crystal facet engineering for various photocatalytic applications. | Lee, Dong-Eun; Reddy, Kasala Prabhakar; Moru, Satyanarayana; Jo, Wan-Kuen; Tonda, Surendar | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ South Carolina, Dept Chem & Biochem, 631 Sumpter St, Columbia, SC 29208 USA; VIT AP Univ, Vellore Inst Technol Andhra Pradesh, Sch Adv Sci, Amaravati 522237, Andhra Pradesh, India | Jo, Wan/AAO-5329-2020; Kasala, Prabhakar Reddy/AFV-7189-2022; Moru, Satyanarayana/AAF-3189-2021; MORU, SATYANARAYANA/AAF-3189-2021; Tonda, Surendar/AAO-3358-2020 | 56605563300; 57144485400; 58562229700; 7103322277; 56114866900 | wkjo@knu.ac.kr;surendar.t86@gmail.com; | APPLIED SURFACE SCIENCE | APPL SURF SCI | 0169-4332 | 1873-5584 | 610 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, COATINGS & FILMS;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2023 | 6.3 | 10.9 | 1.98 | 2025-06-25 | 13 | 16 | WO3 (001); Facet engineering; S-scheme charge transfer; Environmental remediation | WATER-TREATMENT; SILVER NANOPARTICLES; DEGRADATION; TIO2; OXIDATION; KINETICS; CO2; OXYTETRACYCLINE; PHOTOREDUCTION; PURIFICATION | Environmental remediation; Facet engineering; g-C<sub>3</sub>N<sub>4</sub>; S-scheme charge transfer; WO<sub>3</sub> (0 0 1) | Catalysts; Charge transfer; Heterojunctions; Light; Light absorption; Light sources; Liquid chromatography; Mass spectrometry; Nanorods; Nanosheets; Organic carbon; Photocatalytic activity; Pollution; Reusability; Separation; Charge-separation; Crystal facets; Environmental remediation; Facet engineering; G-C3N4; Hybrid catalysts; Induced charges; Performance; S-scheme charge transfer; WO3 (0 0 1); Carbon nitride | English | 2023 | 2023-02-01 | 10.1016/j.apsusc.2022.155569 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Identifying facilitators of and barriers to the adoption of dynamic consent in digital health ecosystems: a scoping review | BackgroundConventional consent practices face ethical challenges in continuously evolving digital health environments due to their static, one-time nature. Dynamic consent offers a promising solution, providing adaptability and flexibility to address these ethical concerns. However, due to the immaturity of the concept and accompanying technology, dynamic consent has not yet been widely used in practice. This study aims to identify the facilitators of and barriers to adopting dynamic consent in real-world scenarios.MethodsThis scoping review, conducted in December 2022, adhered to the PRISMA Extension for Scoping Reviews guidelines, focusing on dynamic consent within the health domain. A comprehensive search across Web of Science, PubMed, and Scopus yielded 22 selected articles based on predefined inclusion and exclusion criteria.ResultsThe facilitators for the adoption of dynamic consent in digital health ecosystems were the provision of multiple consent modalities, personalized alternatives, continuous communication, and the dissemination of up-to-date information. Nevertheless, several barriers, such as consent fatigue, the digital divide, complexities in system implementation, and privacy and security concerns, needed to be addressed. This study also investigated current technological advancements and suggested considerations for further research aimed at resolving the remaining challenges surrounding dynamic consent.ConclusionsDynamic consent emerges as an ethically advantageous method for digital health ecosystems, driven by its adaptability and support for continuous, two-way communication between data subjects and consumers. Ethical implementation in real-world settings requires the development of a robust technical framework capable of accommodating the diverse needs of stakeholders, thereby ensuring ethical integrity and data privacy in the evolving digital health landscape. | Lee, Ah Ra; Koo, Dongjun; Kim, Il Kon; Lee, Eunjoo; Kim, Hyun Ho; Yoo, Sooyoung; Kim, Jeong-Hyun; Choi, Eun Kyung; Lee, Ho-Young | Seoul Natl Univ, Bundang Hosp, Off eHlth Res & Business, Seongnam, South Korea; Seoul Natl Univ, Interdisciplinary Program Bioengn, Seoul, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Comp Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Nursing Sci, Coll Nursing, Daegu, South Korea; Jeonbuk Natl Univ, Res Inst Clin Med, Dept Pediat, Jeonju, South Korea; Jeonbuk Natl Univ Hosp, Biomed Res Inst Clin Med, Jeonju, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Psychiat, Seongnam, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Publ Hlth Med Serv, Seongnam, South Korea; Seoul Natl Univ, Med Res Ctr, Inst Human Behav Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med Humanities & Med Educ, Daegu, South Korea; Seoul Natl Univ, Bundang Hosp, Dept Nucl Med, Seongnam, South Korea | koo, dongjun/HKE-1497-2023; choi, eunkyung/JUF-8150-2023 | 57207456585; 57851155100; 14919454400; 56502620400; 57203629820; 8426359900; 57216641686; 57391706800; 56237826800 | debobkr@snubh.org; | BMC MEDICAL ETHICS | BMC MED ETHICS | 1472-6939 | 24 | 1 | SSCI;SCIE | ETHICS;MEDICAL ETHICS;SOCIAL SCIENCES, BIOMEDICAL | 2023 | 3 | 10.9 | 1.52 | 2025-06-25 | 4 | 6 | Dynamic consent; Digital health; Data sovereignty; Blockchain; Consent systems | BROAD CONSENT; MEDICINE | Blockchain; Consent systems; Data sovereignty; Digital health; Dynamic consent | Communication; Ecosystem; Humans; Informed Consent; Privacy; Technology; ecosystem; human; informed consent; interpersonal communication; privacy; technology | English | 2023 | 2023-12-01 | 10.1186/s12910-023-00988-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Minimizing Input Current Ripple for Four-Phase Input-Parallel Output-Series DCDC Converter With Phase-Shift Modulation | This letter proposes a pulse width modulation (PWM) scheme based on phase-shift modulation for the four-phase input-parallel output-series (4P-IPOS) converter. And operation with dual-output configuration is investigated. The natural output voltages and inductor currents balancing can be achieved even without any extra components or dedicated control. In addition, compared with the conventional PWM scheme, performance improves. The input current ripple is reduced significantly at high voltage gain. An 800-W prototype of the 4P-IPOS converter was built and tested to verify the performance of the suggested scheme. | Van Bui, Dai; Cha, Honnyong | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea | ; Bui, Van-Dai/AAE-6202-2022; BUI, VAN-DAI/AAE-6202-2022 | 57221961296; 24450248400 | buidai68@gmail.com;chahonny@knu.ac.kr; | IEEE TRANSACTIONS ON POWER ELECTRONICS | IEEE T POWER ELECTR | 0885-8993 | 1941-0107 | 38 | 7 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2023 | 6.6 | 10.9 | 1.71 | 2025-06-25 | 9 | 15 | Current balancing; input-parallel output-series (IPOS) converter; pulsewidth modulation (PWM); ripple cancellation; voltage balancing | ASYMMETRICAL PWM SCHEME; HIGH STEP-UP; BOOST CONVERTER; DC/DC CONVERTER | Current balancing; input-parallel output-series (IPOS) converter; pulsewidth modulation (PWM); ripple cancellation; voltage balancing | DC-DC converters; Electric inverters; Current balancing; Inductor; Input-parallel output-series converter; Output series; Parallel output; Pulsewidth modulations (PWM); Ripple cancellation; Series converter; Voltage balancing; Pulse width modulation | English | 2023 | 2023-07 | 10.1109/tpel.2023.3264792 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
