○ Article ⓘ Information awareness, access and socioeconomic deprivation: a cross-jurisdictional study of local health information ⓘ Purpose: This study investigated the relationship among information awareness, access and socioeconomic deprivation in the context of local health information. Drawing on theories of information poverty and the digital divide, this study examined how socioeconomic deprivation influences individuals’ ability to become aware of and access local health information. Design/methodology/approach: Using survey data from three jurisdictions in South Korea’s Seoul Metropolitan Area, this study examined how socioeconomic factors influence information awareness and access at both the macro level (jurisdiction) and the micro level (individual). Findings: The findings revealed significant differences in information awareness and access across jurisdictions with varying levels of socioeconomic deprivation. Participants from areas with lower socioeconomic deprivation reported greater confidence in their ability to access and evaluate health information. At an individual level, socioeconomic deprivation negatively affected information awareness and access. Information awareness was shown to mediate the effects of socioeconomic deprivation on information access, although the degree of mediation varied across different dimensions of information access, such as physical, intellectual and social access. Originality/value: The study contributes to the literature focused on the digital divide, information poverty and local information landscapes by studying information awareness as a mediator in shaping information access. The findings of this study can guide health information service providers and system designers in developing customized strategies that cater to the unique needs of various communities and socioeconomic groups. © 2025, Emerald Publishing Limited. ⓘ Oh, Sanghee; Lee, Myeong; Lee, Jongwook ⓘ Department of Library and Information Science, Sungkyunkwan University, Seoul, South Korea; Department of Information Sciences and Technology, George Mason University, Arlington, VA, United States; Department of Library and Information Science, Kyungpook National University, Daegu, South Korea ⓘ ⓘ 15069782300; 57054227300; 54988756200 ⓘ mlee89@gmu.edu; ⓘ Aslib Journal of Information Management ⓘ ASLIB J INFORM MANAG ⓘ 2050-3806 1758-3748 SSCI;SCIE INFORMATION SCIENCE & LIBRARY SCIENCE;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 3.1 22.0 N/A ⓘ 0 ⓘ ⓘ Health information behavior; Information access; Information awareness; Information inequality; Socioeconomic deprivation ⓘ Digital divide; Health information behavior; Health informations; Information access; Information awareness; Information behaviours; Information inequality; Information poverties; Socio-economics; Socioeconomic deprivation; Information services ⓘ English Article in press 2025 10.1108/ajim-11-2024-0863 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Resolved Stellar Mass Estimation of Nearby Late-type Galaxies for the SPHEREx Era: Dependence on Stellar Population Synthesis Models ⓘ The upcoming all-sky infrared spectrophotometric SPHEREx mission is set to provide spatially resolved stellar mass maps of nearby galaxies, offering more detailed insights than integrated light observations. In this study, we develop a strategy for estimating stellar mass using SPHEREx by examining the dependence on different stellar population synthesis (SPS) models and proposing new scaling relations based on simulated SPHEREx data. We estimate the resolved stellar masses of 19 nearby late-type galaxies from the PHANGS-MUSE survey, treating these as fiducial masses. By testing four SPS models covering infrared wavelengths, i.e., E-MILES, Bruzual & Charlot (BC03), Charlot & Bruzual (CB19), and FSPS, we find systematic differences in mass-to-light ratios at 3.6 mu m (M*/L3.6 mu m) among the SPS models. In particular, BC03 and CB19 yield mass-to-light ratios on average similar to 0.2-0.3 dex lower than those from E-MILES and FSPS. These mass-to-light ratios strongly correlate with stellar age, indicating a significant impact of young stellar populations on stellar mass measurements. Our analysis, incorporating fiducial masses and simulated SPHEREx data, identifies the 1.6 mu m band as the optimal wavelength for stellar mass estimation, with the lowest scatter (0.15-0.20 dex) of the stellar mass. This scatter can be further reduced to 0.10-0.12 dex across all SPS models by incorporating optical and SPHEREx colors. These results can provide guidance for measuring the stellar masses of the numerous nearby galaxies that SPHEREx will survey. ⓘ Lee, Jeong Hwan; Kim, Minjin; Kim, Taehyun; Shim, Hyunjin; Ho, Luis C.; Hwang, Ho Seong; Song, Hyunmi; Kim, Dohyeong; Yang, Yujin; Jeong, Woong-Seob ⓘ Seoul Natl Univ, Res Inst Basic Sci, Seoul 08826, South Korea; Seoul Natl Univ, Dept Phys & Astron, 1 Gwanak Ro, Seoul 08826, South Korea; Kyungpook Natl Univ, Ctr High Energy Phys, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China; Seoul Natl Univ, SNU Astron Res Ctr, Seoul 08826, South Korea; Macquarie Univ, Australian Astron Opt, 105 Delhi Rd, N Ryde, NSW 2113, Australia; Chungnam Natl Univ, Dept Astron & Space Sci, Daejeon 34134, South Korea; Pusan Natl Univ, Dept Earth Sci, Busan 46241, South Korea; Korea Astron & Space Sci Inst, Daejeon 34055, South Korea; Univ Sci & Technol, Daejeon 34113, South Korea ⓘ ; HWANG, Ho/AAS-6010-2020 ⓘ 57195344163; 56898213300; 57050549000; 14061137700; 57225302746; 15131707100; 35749280400; 55574223678; 7409384232; 7102145940 ⓘ mkim.astro@gmail.com; ⓘ ASTRONOMICAL JOURNAL ⓘ ASTRON J ⓘ 0004-6256 1538-3881 169 3 SCIE ASTRONOMY & ASTROPHYSICS ⓘ 2024 5.1 22.0 0 2025-05-07 ⓘ 1 1 ⓘ STAR-FORMATION HISTORY; POLYCYCLIC AROMATIC-HYDROCARBONS; TO-LIGHT RATIOS; S(4)G IRAC 3.6; SPITZER SURVEY; ASSEMBLY GAMA; MIDINFRARED PROPERTIES; INFRARED SPECTROSCOPY; METALLICITY RELATION; EVOLUTIONARY TRACKS ⓘ ⓘ ⓘ English 2025 2025-03-03 10.3847/1538-3881/adb285 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Ni-based electrodes on 3D substrates: Development and performance for asymmetric supercapacitors ⓘ To produce high-performance supercapacitors, an easy hydrothermal method was utilized to fabricate the positive electrode employing transition metal nickel and carbonate, which exhibits good wettability and reacts well with aqueous electrolytes. In addition, electrodes without and with a 3D Ni foam substrate were compared, focusing on their surface area and electrochemical performance. The electrodes were fabricated using carbonate (CO32-) based compounds with high wettability. The Ni-2(CO3)(OH)(2) electrode without Ni foam substrates demonstrated higher electrochemical values at low current densities, while the Ni-2(CO3)(OH)(2) electrode with Ni foam substrates exhibited higher capacitance at increased current densities. As the current density increased from 3 A/g to 15 A/g, the capacitance of Ni-2(CO3)(OH)(2) without Ni foam and with Ni foam electrodes decreased by 58.1 % and 46.5 %, respectively. This indicates that higher electrochemical stability is possessed by electrodes directly deposited on Ni foam substrates. The significance of substrate selection for enhancing electrochemical performance is highlighted, with the Ni-2(CO3)(OH)(2) electrode deposited on Ni foam substrate showing a high capacitance of 101.5mAh/g at a current density of 3 A/g. Additionally, an asymmetric supercapacitor comprising Ni-2(CO3)(OH)(2) electrodes with Ni foam and graphene as positive and negative electrode, respectively, demonstrated a remarkable energy density of 22.1 W h kg(-1) and power density of 673.1 W kg(-1) at a current density of 2 A/g. Impressively, excellent cycling stability was exhibited by this asymmetric supercapacitor, with similar to 83.4 % capacitance retention after 5000 cycles. ⓘ Lee, Hyun Woo; Roh, Jong Wook; Kim, Kwang Ho; Lee, Damin ⓘ Pusan Natl Univ, Sch Mat Sci & Engn, San 30 Jangjeon Dong, Busan 609735, South Korea; Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Daegu 41566, South Korea; DGIST, Div Nanotechnol, 333 Techno Jungang Daero, Daegu 42988, South Korea ⓘ Kim, Hee-Je/O-3501-2019 ⓘ 57192499694; 25638796100; 59774157800; 57194601076 ⓘ damin91@knu.ac.kr; ⓘ JOURNAL OF ELECTROANALYTICAL CHEMISTRY ⓘ J ELECTROANAL CHEM ⓘ 1572-6657 1873-2569 979 SCIE CHEMISTRY, ANALYTICAL;ELECTROCHEMISTRY ⓘ 2024 4.1 22.1 0 2025-05-07 ⓘ 0 0 Transition metal; Ni foam substrate; Pseudocapacitors; Hydrothermal method; Supercapacitor ⓘ XPS SPECTRA; NANOSHEETS; NICKEL; COMPOSITES; CARBON; OXIDE ⓘ Hydrothermal method; Ni foam substrate; Pseudocapacitors; Supercapacitor; Transition metal ⓘ Cobalt compounds; Supercapacitor; 'current; Asymmetric supercapacitor; Foam substrates; Hydrothermal methods; Ni 2; Ni foam; Ni foam substrate; Performance; Pseudocapacitors; Capacitor bank ⓘ English 2025 2025-02-15 10.1016/j.jelechem.2024.118907 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Non-existence of proper η-Einstein Kenmotsu manifolds ⓘ In 1972, Kenmotsu [A class of almost contact Riemannian manifolds, Tohoku Math. J. (2) 24 (1972) 93-103] defined the notion of Kenmotsu manifolds. He has also studied the properties of proper eta-Einstein Kenmotsu manifolds, and proved some basic interesting results. These results have been used by a plenty of authors in establishing their main results on Kenmotsu manifolds. Naturally, the question of existence of proper eta-Einstein Kenmotsu manifold is a prime question in the study of contact geometry. The main goal of this paper is to discuss the existence of proper eta-Einstein Kenmotsu manifolds and to refine some of Kenmotsu's results. The results of this paper may be used as an erratum of many published papers on Kenmotsu manifolds. In this sequence, we also address the existence of conharmonically flat Kenmotsu manifolds, conformal Ricci flow and almost Ricci solitons on Kenmotsu manifolds. ⓘ Chaubey, Sudhakar Kumar; Suh, Young Jin ⓘ Univ Technol & Appl Sci, Dept Informat Technol, Sect Math, POB 77, Shinas 324, Oman; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea ⓘ Chaubey, S./ABB-6952-2021 ⓘ 36117508600; 57205268556 ⓘ sk22math@yahoo.co.in; yjsuh@knu.ac.kr; sk22_math@yahoo.co.in; ⓘ INTERNATIONAL JOURNAL OF GEOMETRIC METHODS IN MODERN PHYSICS ⓘ INT J GEOM METHODS M ⓘ 0219-8878 1793-6977 22 08 SCIE PHYSICS, MATHEMATICAL ⓘ 2024 2.2 22.1 0 2025-05-07 ⓘ 0 0 Kenmotsu manifolds; conformal curvature tensor; conharmonic curvature tensor; proper eta -Einstein manifold; conformal Ricci flow; almost Ricci soliton ⓘ CONHARMONIC CURVATURE TENSOR; RICCI; SOLITONS ⓘ almost Ricci soliton; conformal curvature tensor; conformal Ricci flow; conharmonic curvature tensor; Kenmotsu manifolds; proper η-Einstein manifold ⓘ ⓘ English 2025 2025-07 10.1142/s0219887825500501 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ On pseudo B-symmetric spacetimes and f(R) gravity ⓘ This paper delivers the characterization of a pseudo B-symmetric spacetimes and we illustrate that a pseudo B-symmetric spacetime admitting Codazzi type of B-tensor represents a perfect fluid spacetime and if this spacetime admits the time-like convergence criterion, then the pseudo B-symmetric spacetime fulfills cosmic strong energy criterion and contains pure matter. Besides, we find in a pseudo B-symmetric spacetime with Codazzi type of B-tensor the electric part of the Weyl tensor vanishes and has Riemann and Weyl compatible vector fields. Furthermore, it is established that the chosen spacetime with Codazzi type of B-tensor is conformally flat and represents a Robertson-Walker spacetime. Also, we calculate the scale factor Psi(t) for these spacetimes in a spatially flat Robertson-Walker spacetime. Finally, we study the impact of this spacetime under f(R) gravity scenario and deduce several energy conditions by considering a new model f(R) = e((alpha R)) -ln(beta R) in which alpha and beta are positive constants. ⓘ Suh, Young Jin; De, Krishnendu; De, Uday Chand ⓘ Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea; Univ Burdwan, Dept Math, Kabi Sukanta Mahavidyalaya, PO Angus, Hooghly 712221, West Bengal, India; Univ Calcutta, Dept Pure Math, Kolkata, West Bengal, India ⓘ ; De, Krishnendu/LWJ-4652-2024 ⓘ 57205268556; 55319393800; 7007046738 ⓘ yjsuh@knu.ac.kr; krishnendu.de@outlook.in; uc-de@yahoo.com; ⓘ INTERNATIONAL JOURNAL OF GEOMETRIC METHODS IN MODERN PHYSICS ⓘ INT J GEOM METHODS M ⓘ 0219-8878 1793-6977 22 02 SCIE PHYSICS, MATHEMATICAL ⓘ 2024 2.2 22.1 0 2025-05-07 ⓘ 1 0 Pseudo symmetric spacetimes; pseudo Z-symmetric spacetimes; perfect fluid spacetimes; pseudo B-symmetric spacetimes; modified gravity ⓘ PERFECT FLUID SPACETIMES; ENERGY CONDITIONS; CURVATURE ⓘ modified gravity; perfect fluid spacetimes; pseudo B -symmetric spacetimes; Pseudo symmetric spacetimes; pseudo Z -symmetric spacetimes ⓘ ⓘ English 2025 2025-02 10.1142/s0219887824502803 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Quantum discord is not extremalized by Gaussian states ⓘ Quantum discord is an important measure of quantum correlations that goes beyond the paradigm of quantum entanglement. However, calculating quantum discord involves optimization over measurements, which is computationally challenging and often infeasible. This raises the intriguing question of Gaussian extremality-whether the quantum discord of a reference Gaussian state can provide a meaningful bound to the quantum discord of the original state. In this paper, we investigate this question by comparing the Gaussian discord of a reference Gaussian state with the quantum discord. ⓘ Lee, Seungmin; Noh, Changsuk; Park, Jiyong ⓘ Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Hanbat Natl Univ, Sch Basic Sci, Daejeon 34158, South Korea ⓘ ⓘ 57200005388; 23991025500; 55716975600 ⓘ cnoh@knu.ac.kr; jiyong.park@hanbat.ac.kr; ⓘ QUANTUM INFORMATION PROCESSING ⓘ QUANTUM INF PROCESS ⓘ 1570-0755 1573-1332 24 3 SCIE PHYSICS, MATHEMATICAL;PHYSICS, MULTIDISCIPLINARY;QUANTUM SCIENCE & TECHNOLOGY ⓘ 2024 2.2 22.1 0 2025-05-07 ⓘ 0 0 Quantum discord; Gaussian extremality; Continuous variable quantum system ⓘ ⓘ Continuous variable quantum system; Gaussian extremality; Quantum discord ⓘ Gaussian distribution; Gaussian noise (electronic); Quantum optics; Continuous variable quantum system; Continuous variables; Gaussian extremality; Gaussian state; Gaussians; Intriguing questions; Optimisations; Quantum correlations; Quantum discords; Quantum system; Quantum entanglement ⓘ English 2025 2025-03-08 10.1007/s11128-025-04693-x ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Yamabe and Ricci solitons on Vaidya spacetime ⓘ The focus of this paper is to investigate the existence of Yamabe solitons and gradient Yamabe solitons on Vaidya spacetime. Our investigation is motivated by the observation in Khatri et al. [Existence of Ricci soliton vector fields on Vaidya spacetime, Phys. Scripta 98 (2023) 115244] that Vaidya spacetime reduces to the Schwarzschild spacetime when it admits a Ricci soliton and the mass is a nonzero constant. However, in Vaidya spacetime, mass is a function of retarded null coordinate u. So, the focus is to find a soliton on Vaidya spacetime such that mass is variable and a function of u instead of being constant. Moreover, in the way to find such a soliton, we see some modification is required in the results of the work by Khatri et al. [Existence of Ricci soliton vector fields on Vaidya spacetime, Phys. Scripta 98 (2023) 115244] and Fasihi-Ramandi [Erratum to existence of Ricci soliton vector fields on Vaidya spacetime (2024), doi:10.13140/RG.2.2.15457.52322]. To this end, we prove a rigidity theorem in a sense that Vaidya spacetime reduces to either the Schwarzschild or Minkowski spacetime, depending on whether the mass is a nonzero constant or zero, respectively, when it admits a Ricci soliton. Furthermore, we discuss the existence of gradient Ricci solitons in each case, addressing overlooked conditions in Khatri et al. [Existence of Ricci soliton vector fields on Vaidya spacetime, Phys. Scripta 98 (2023) 115244] and Fasihi-Ramandi [Erratum to existence of Ricci soliton vector fields on Vaidya spacetime (2024), doi:10.13140/RG.2.2.15457.52322]. Finally, we remark on the existence of conformal Ricci solitons on this spacetime of interest in the light of recent work by Chhakchhuak and Singh [Conformal Ricci solitons on Vaidya spacetime, Gen. Relativ. Gravit. 56(1) (2024) 11] and Fasihi-Ramandi [Erratum to conformal Ricci solitons on Vaidya spacetime (2024), doi:10.13140/RG.2.2.28879.29605]. While Chhakchhuak and Singh had initially proven that such solitons exist, we argue that the study of conformal Ricci solitons is not possible on Vaidya spacetime. © 2025 World Scientific Publishing Company. ⓘ Rani, Savita; Gupta, Ram Shankar; Suh, Young Jin ⓘ International Centre for Theoretical Sciences, Tata Institute of Fundamental Research, Bengaluru, 560089, India; University School of Basic and Applied Sciences, Guru Gobind Singh Indraprastha University, Sector-16C, Dwarka, New Delhi, 110078, India; Department of Mathematics and Research Institute, Real and Complex Manifolds (RIRCM), Kyungpook National University, Daegu, 41566, South Korea ⓘ ⓘ 57609444500; 8551352900; 59713214000 ⓘ mansavi.14@gmail.com; ⓘ International Journal of Geometric Methods in Modern Physics ⓘ INT J GEOM METHODS M ⓘ 0219-8878 1793-6977 SCIE PHYSICS, MATHEMATICAL ⓘ 2024 2.2 22.1 ⓘ 0 ⓘ ⓘ gradient Ricci soliton; gradient Yamabe soliton; Minkowski space; Ricci soliton; Schwarzschild metric; Vaidya spacetime; Yamabe soliton ⓘ ⓘ English Article in press 2025 10.1142/s0219887825502184 ⓘ 바로가기 바로가기 바로가기
○ ○ Article ⓘ Antibacterial and Antibiofilm Activity of Layers Enriched with Silver Nanoparticles on Orthodontic Microimplants ⓘ Orthodontic microimplants have revolutionized anchorage in orthodontics but remain vulnerable to microbial colonization, potentially leading to infection and failure. Surface modifications incorporating silver nanoparticles (AgNPs) offer antimicrobial benefits, providing long-term protection against bacterial infections, while improving partial osseointegration. This study investigates hybrid coatings enriched with AgNPs, calcium (Ca), and phosphorus (P) to improve antimicrobial efficacy and reduce biofilm formation. Microimplants fabricated from the Ti6Al4V alloy were divided into six groups with varying surface treatments, including etching in hydrofluoric acid and hybrid layers containing 0.5 mol% AgNPs and CaP. Antibacterial activity was evaluated using agar diffusion and biofilm formation assays against S. aureus, E. coli, and S. mutans. Surface roughness was analyzed and correlated with biofilm formation. The model assessing the impact of biomaterials on S. aureus biofilm revealed a strong association (R2 = 0.94), with biomaterial choice significantly influencing biofilm formation. The model for E. coli biofilm exhibited exceptional predictability (R2 = 0.99). The model for S. mutans biofilm demonstrated an association (R2 = 0.68). Hybrid coatings exhibited a promising antimicrobial activity. Biofilm formation was higher on microimplants with rougher surfaces. Hybrid coatings enriched with AgNPs and CaP enhance antimicrobial properties and partially reduce biofilm formation. It is suggested that the optimization of microimplant surface areas varies according to function. An enhanced performance can be achieved by maintaining a smooth surface for soft tissue contact, while incorporating a rough surface enriched with bactericidal and bioactive modifiers for bone contact areas. ⓘ Sycinska-Dziarnowska, Magdalena; Ziabka, Magdalena; Cholewa-Kowalska, Katarzyna; Klesiewicz, Karolina; Spagnuolo, Gianrico; Lindauer, Steven J.; Park, Hyo-Sang; Wozniak, Krzysztof ⓘ Pomeranian Med Univ, Dept Maxillofacial Orthopaed & Orthodont, Al Powst Wlkp 72, PL-70111 Szczecin, Poland; AGH Univ Krakow, Fac Mat Sci & Ceram, Dept Ceram & Refractories, Al A Mickiewicza 30, PL-30059 Krakow, Poland; AGH Univ Krakow, Fac Mat Sci & Ceram, Dept Glass Technol & Amorphous Coatings, PL-30059 Krakow, Poland; Jagiellonian Univ, Fac Pharm, Med Coll, Dept Pharmaceut Microbiol, 9 Med St, PL-30688 Krakow, Poland; Univ Naples Federico II, Dept Neurosci Reprod & Odontostomatol Sci, I-80131 Naples, Italy; Kaohsiung Med Univ, Coll Dent Med, Sch Dent, Kaohsiung 80708, Taiwan; Virginia Commonwealth Univ, Sch Dent, Dept Orthodont, Richmond, VA 23103 USA; Kyungpook Natl Univ, Coll Dent, Dept Orthodont, Daegu 41940, South Korea ⓘ ; Klesiewicz, Karolina/U-7432-2018; Ziąbka, Magdalena/N-8788-2018; Sycińska-Dziarnowska, Magdalena/AAC-9093-2021; Cholewa-Kowalska, Katarzyna/W-4907-2018; Spagnuolo, Gianrico/N-5110-2015 ⓘ 57219395589; 36877220500; 6506871323; 55252748400; 7003679853; 7003848575; 55754836800; 57196720587 ⓘ magdalena.sycinska.dziarnowska@pum.edu.pl; parkhs@knu.ac.kr; ⓘ JOURNAL OF FUNCTIONAL BIOMATERIALS ⓘ J FUNCT BIOMATER ⓘ 2079-4983 16 3 SCIE ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2024 5.2 22.2 0 2025-05-07 ⓘ 1 1 antibacterial function; bioactive coatings; orthodontic microimplants; silver nanoparticles ⓘ IMPLANTS; SURFACE; OSSEOINTEGRATION; BIOFILM ⓘ antibacterial function; bioactive coatings; orthodontic microimplants; silver nanoparticles ⓘ Dental orthoses; Diffusion coatings; Escherichia coli; Etching; Silver alloys; Silver nanoparticles; Titanium alloys; hydrofluoric acid; phosphorus; silver nanoparticle; Antibacterial functions; Antibacterials; Antibiofilms; Bioactive coatings; Biofilm formation; E. coli; Hybrid coating; Orthodontic microimplant; Rough surfaces; S. aureus; agar diffusion; antibacterial activity; antibiofilm activity; antimicrobial activity; Article; bacterial strain; biofilm; biomechanics; confocal laser scanning microscopy; confocal microscopy; controlled study; Escherichia coli; microbial colonization; nonhuman; orthodontic anchorage; orthodontics; osseointegration; osteoblast; scanning electron microscopy; Staphylococcus aureus; Streptococcus mutans; surface analysis; surface texture analysis; topography; Biofilms ⓘ English 2025 2025-02-22 10.3390/jfb16030078 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effect of Pixel Offset Adjustments for XY Plane Dimensional Compensation in Digital Light Processing 3D Printing on the Surface Trueness and Fit of Zirconia Crowns ⓘ This study aimed to evaluate the effect of pixel offset adjustments in digital light processing (DLP) three-dimensional (3D) printing on the marginal and internal fit and surface trueness of zirconia crowns. Zirconia crowns were designed using dental computer-aided design software (Dentbird; Imagoworks) and fabricated with a vat photopolymerization DLP 3D printer (TD6+; 3D Controls) under three pixel offset conditions (-1, 0, and 1). Pixel offset refers to the controlled modification of the outermost pixels in the XY plane during printing to compensate for potential dimensional inaccuracies. The marginal and internal fit was assessed using a triple-scan protocol and quantified using root mean square (RMS) values. Surface trueness was evaluated by measuring RMS, positive and negative errors between the designed and fabricated crowns. Statistical analyses included one-way ANOVA and Pearson correlation analysis (alpha = 0.05). The Pixel offset had a significant effect on fit accuracy and surface trueness (p m at a pixel offset of 1 (114.5 +/- 14.6 mu m), while a pixel offset of -1 (85.5 +/- 18.6 mu m) remained within acceptable limits (p = 0.003). Surface trueness worsened with increasing pixel offset, showing greater positive errors (p < 0.001). Optimizing pixel offset in DLP 3D printing is crucial to ensuring clinically acceptable zirconia crowns. Improper settings may increase marginal discrepancies and surface errors, compromising restoration accuracy. ⓘ Son, Keunbada; Lee, Ji-Min; Jang, Kyoung-Jun; Lee, Sang-Kyu; Hwang, Jun Ho; Lee, Jong Hoon; Kim, Hyun Deok; Kim, So-Yeun; Lee, Kyu-Bok ⓘ Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; 3D Controls Co Ltd, Busan 46721, South Korea; Kyungpook Natl Univ, Inst Adv Convergence Technol, Daegu 41061, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea ⓘ SON, Keunbada/AAG-8089-2019; Son, Keunbada/AAG-8089-2019 ⓘ 57202916520; 57193811541; 57202904866; 57221452704; 57204783286; 57204786073; 55663858300; 59510685500; 15925571200 ⓘ oceanson@knu.ac.kr; wlals9408@naver.com; jangkj@3dcontrols.co.kr; leesk@3dcontrols.co.kr; hjh@iact.or.kr; laser@knu.ac.kr; hdkim@knu.ac.kr; soyeunkim179@gmail.com; kblee@knu.ac.kr; ⓘ JOURNAL OF FUNCTIONAL BIOMATERIALS ⓘ J FUNCT BIOMATER ⓘ 2079-4983 16 3 SCIE ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2024 5.2 22.2 0 2025-05-07 ⓘ 0 0 digital light processing 3D printing; zirconia crowns; pixel offset; marginal and internal fit; surface trueness ⓘ INTERNAL FIT; MARGINAL FIT; STEREOLITHOGRAPHY; ADAPTATION; CERAMICS ⓘ digital light processing 3D printing; marginal and internal fit; pixel offset; surface trueness; zirconia crowns ⓘ Digital printing; zirconium oxide; Digital light processing; Digital light processing three-dimensional printing; Marginal and internal fit; Marginal discrepancy; Marginals; Pixel offset; Root Mean Square; Surface trueness; Three-dimensional-printing; Zirconium crown; Article; compensation; computer aided design; correlation analysis; data interpretation; digital light processing; geometry; human; leg inequality; nanofabrication; polymerization; root mean squared error; three dimensional printing; three-dimensional imaging; type II error; Printing presses ⓘ English 2025 2025-03-14 10.3390/jfb16030103 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Spatial Platform for Periodontal Ligament Angulation and Regeneration: In Vivo Pilot Study ⓘ The periodontal ligament (PDL) is a fibrous connective tissue that anchors the tooth-root surface to the alveolar bone with specific orientations. It plays a crucial role in functional restoration, optimal position stabilities, biomechanical stress transmission, and appropriate tissue remodeling in response to masticatory loading conditions. This pilot study explored spatial microarchitectures to promote PDL orientations while limiting mineralized tissue formation. A computer-designed perio-complex scaffold was developed with two parts: (1) PDL-guiding architectures with defined surface topography and (2) a bone region with open structures. After SEM analysis of micropatterned topographies on PDL-guiding architectures, perio-complex scaffolds were transplanted into two-wall periodontal defects in the canine mandible. Despite the limited bone formation at the 4-week timepoint, bone parameters in micro-CT quantifications showed statistically significant differences between the no-scaffold and perio-complex scaffold transplantation groups. Histological analyses demonstrated that the PDL-guiding architecture regulated fiber orientations and facilitated the functional restoration of PDL bundles in immunohistochemistry with periostin and decorin (DCN). The perio-complex scaffold exhibited predictable and controlled fibrous tissue alignment with specific angulations, ensuring spatial compartmentalization for PDL tissues and bone regenerations. These findings highlighted that the perio-complex scaffold could serve as an advanced therapeutic approach to contribute periodontal tissue regeneration and functional restoration in tooth-supporting structures. ⓘ Kim, Min Guk; Kim, Do-Yeon; Ko, Hyoung-Gon; Byun, Jin-Seok; Kim, Joong-Hyun; Park, Chan Ho ⓘ Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 41940, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Pharmacol, Daegu 41940, South Korea; Kyung Hee Univ, Coll Dent, Dept Oral Anat & Dev Biol, Seoul 02447, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Med, Daegu 41940, South Korea; Osong Med Innovat Fdn KBIO Hlth, Non Clin Evaluat Ctr, Cheongju 28160, South Korea ⓘ Kim, Do-Yeon/AET-3021-2022; Ko, Hyoung-Gon/KQU-8680-2024 ⓘ 57219538160; 59816075400; 14522654800; 55430621800; 24923231800; 55728043300 ⓘ wndgus@kbiohealth.kr; chanho@knu.ac.kr; ⓘ JOURNAL OF FUNCTIONAL BIOMATERIALS ⓘ J FUNCT BIOMATER ⓘ 2079-4983 16 3 SCIE ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2024 5.2 22.2 0 2025-05-07 ⓘ 0 0 periodontal ligament (PDL); additive manufacturing; periodontal tissues; tissue engineering; regenerative medicine ⓘ PERIOSTIN; TOOTH ⓘ additive manufacturing; periodontal ligament (PDL); periodontal tissues; regenerative medicine; tissue engineering ⓘ Computerized tomography; Ligaments; Mastication; Regenerative medicine; Restoration; Scaffolds; Scaffolds (biology); Tissue regeneration; biological marker; butorphanol; cefazolin; cyclohexane derivative; decorin; diaminobenzidine; transcription factor RUNX2; Complex scaffolds; Fibrous connective tissue; Functionals; In-vivo; Periodontal ligament; Periodontal tissue; Pilot studies; Regenerative medicine; Tissues engineerings; alveolar bone; animal experiment; animal tissue; Article; biomechanics; bone density; bone regeneration; bone volume fraction; connective tissue; human; immunohistochemistry; micro-computed tomography; nonhuman; orientation; periodontal ligament; pilot study; regeneration; soft tissue; three-dimensional imaging; tissue regeneration; tooth extraction; topography; Bone ⓘ English 2025 2025-03-13 10.3390/jfb16030099 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Three-Dimensional Assessment of Dental Enamel Microcrack Progression After Orthodontic Bracket Debonding Using Optical Coherence Tomography ⓘ The current study aimed to quantify the length progression of enamel microcracks (EMCs) after debonding metal and ceramic brackets, implementing OCT as a diagnostic tool. The secondary objectives included a three-dimensional assessment of EMC width and depth and the formation of new EMCs. OCT imaging was performed on 16 extracted human premolars before bonding and after debonding. Debonding was conducted with a universal Instron machine, with ARI values recorded. Additionally, 2D and 3D OCT images were employed to detect EMC formation and progression. Enface images quantified the length, width, and number of EMCs, and the length and width were analyzed using Image J (1.54f) and MATLAB (R2014b), respectively. Sagittal cross-sectional images were used for EMC depth analysis. A paired t-test showed significant differences in the length, width, and number of EMCs after debonding (p-value < 0.05), while the Wilcoxon non-parametric test indicated significant EMC depth changes (p-value < 0.05). No significant results were identified for the EMC number in ceramic brackets and EMC depth in metal brackets. Three-dimensional OCT imaging monitored existing EMCs at higher risk of progression and detected new EMCs following orthodontic bracket debonding. This study provides novel insights into EMC progression regarding the length, width, depth, and number after debonding. ⓘ Hamdan, Ahmed Haj; Saleah, Sm Abu; Seong, Daewoon; Ravichandran, Naresh Kumar; Wijesinghe, Ruchire Eranga; Han, Sangyeob; Kim, Jeehyun; Jeon, Mansik; Park, Hyo-Sang ⓘ Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu 41940, South Korea; Kyungpook Natl Univ, ICT Convergence Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Basic Sci Inst, Ctr Sci Instrumentat, 169-148 Gwahak Ro, Daejeon 34133, South Korea; Sri Lanka Inst Informat Technol, Fac Engn, Dept Elect & Elect Engn, Malabe 10115, Sri Lanka; Sri Lanka Inst Informat Technol, Ctr Excellence Informat Elect & Transmiss CIET, Malabe 10115, Sri Lanka ⓘ ; Wijesinghe, Ruchire/K-3797-2016; Han, Sangyeob/W-3206-2018; RAVICHANDRAN, NARESH KUMAR/D-2190-2017 ⓘ 59524629800; 57218499446; 57212512353; 57125825900; 56018152300; 57193695305; 7601373350; 24171094000; 55754836800 ⓘ drahmadhamdan7@knu.ac.kr; abu.saleah@knu.ac.kr; smc7095@knu.ac.kr; nareshr.9169@gmail.com; eranga.w@sliit.lk; syhan850224@knu.ac.kr; jeehk@knu.ac.kr; msjeon@knu.ac.kr; parkhs@knu.ac.kr; ⓘ JOURNAL OF FUNCTIONAL BIOMATERIALS ⓘ J FUNCT BIOMATER ⓘ 2079-4983 16 1 SCIE ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS ⓘ 2024 5.2 22.2 0 2025-05-07 ⓘ 0 0 enamel; microcracks; metal brackets; ceramic brackets; orthodontic brackets; optical coherence tomography (OCT); 3D imaging ⓘ CRACKS; DAMAGE ⓘ 3D imaging; ceramic brackets; enamel; metal brackets; microcracks; optical coherence tomography (OCT); orthodontic brackets ⓘ Article; ceramics; clinical article; controlled study; enamel; human; optical coherence tomography; orthodontics; randomized controlled trial; spectral domain optical coherence tomography; three-dimensional imaging; tooth root canal ⓘ English 2025 2025-01 10.3390/jfb16010007 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Concave functions and positive block matrices ⓘ Let f (t) be a nonnegative concave function on [0,infinity). For a positive (semidefinite) matrix partitioned into four blocks such that AX = XA or BX = XB, we prove that & Vert; f ([A X* X B]) & Vert; <= 2 & Vert; f (A+B/ 2)& Vert; for all unitarily invariant norms. The case X=0 is already new, contains two classical trace inequalities due to Rotfel'd and von Neumann, and generalizes an important basic majorization. Our proof is based, and also extends, a theorem of Bourin and Mhanna involving the width of the numerical range of X. For Schatten q-quasinorms, 0 < q < 1, and nonnegative convex functions vanishing at 0, we obtain the reverse inequality. ⓘ Lee, Eun-Young ⓘ Kyungpook Natl Univ, KNU Ctr Nonlinear Dynam, Dept Math, Daegu 702701, South Korea ⓘ ⓘ 55371789400 ⓘ eylee89@knu.ac.kr; ⓘ LINEAR ALGEBRA AND ITS APPLICATIONS ⓘ LINEAR ALGEBRA APPL ⓘ 0024-3795 1873-1856 712 SCIE MATHEMATICS, APPLIED;MATHEMATICS ⓘ 2024 1.1 22.3 0 2025-05-07 ⓘ 0 0 Positive block matrices; Functional calculus; Numerical range; Norm inequalities ⓘ NORM INEQUALITY ⓘ Functional calculus; Norm inequalities; Numerical range; Positive block matrices ⓘ Block matrix; Concave function; Functional calculus; Non negatives; Norm inequality; Numerical range; Positive block matrix; Positive semidefinite matrices; Trace inequalities; Unitarily invariant norm; Choquet integral ⓘ English 2025 2025-05-01 10.1016/j.laa.2025.02.014 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Data-Efficient Reinforcement Learning Framework for Autonomous Flight Based on Real-World Flight Data ⓘ Recently, autonomous flight has emerged as a key technology in the aerospace and defense sectors; however, traditional code-based autonomous flight systems face limitations in complex environments. Although reinforcement learning offers an alternative, its practical application in real-world settings is hindered by the substantial data requirements. In this study, we develop a framework that integrates a Generative Adversarial Network (GAN) and Hindsight Experience Replay (HER) into model-based reinforcement learning to enhance data efficiency and accuracy. We compared the proposed framework against existing algorithms in actual quadcopter control. In the comparative experiment, we demonstrated an improvement of up to 70.59% in learning speed, clearly highlighting the impact of the environmental model. To the best of our knowledge, this study is the first where a GAN and HER are combined with model-based reinforcement learning, and it is expected to contribute significantly to the practical application of reinforcement learning in autonomous flight. ⓘ Lee, Uicheon; Lee, Seonah; Kim, Kyonghoon ⓘ Gyeongsang Natl Univ, Dept AI Convergence Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Software Engn, Jinju 52828, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea ⓘ ⓘ 58722380300; 25822639700; 59819060900 ⓘ 2024211026@gnu.ac.kr; saleese@gnu.ac.kr; kyong.kim@knu.ac.kr; ⓘ DRONES ⓘ DRONES-BASEL ⓘ 2504-446X 9 4 SCIE REMOTE SENSING ⓘ 2024 4.8 22.3 0 2025-05-07 ⓘ 0 0 MBRL (model-based reinforcement learning); GANs (generative adversarial networks); HER (hindsight experience replay); autonomous flight ⓘ ⓘ autonomous flight; GANs (generative adversarial networks); HER (hindsight experience replay); MBRL (model-based reinforcement learning) ⓘ Adversarial machine learning; Contrastive Learning; Federated learning; Reinforcement learning; Adversarial networks; Autonomous flight; Experience replay; Generative adversarial network; Hindsight experience replay; Learning frameworks; Model-based reinforcement learning; Real-world; Reinforcement learnings; Generative adversarial networks ⓘ English 2025 2025-03-31 10.3390/drones9040264 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Remarks on finite pseudo-chain rings ⓘ We consider a class of local rings that is properly larger than that of chain rings and investigate its properties. We show that when restricted to finite rings, elements of such rings can be factorized into a finite product of irreducible elements, and the length of such factorization is unique, although the factorization itself is far from being unique. Using these results, we determine the minimal number of generators required for each ideal. We also show that several nontrivial examples of such rings appear as a subring of a chain ring and show that such rings can be constructed using techniques commonly used in the field of multiplicative ideal theory. We choose a class of such rings and investigate the basic properties of rings induced from them (including the number of elements and ideals and the unit group structure of such a ring), which are directly associated with the structure of cyclic codes over such rings. ⓘ Kim, Boran; Choi, Hyun Seung ⓘ Kyungpook Natl Univ, Dept Math Educ, Daegu 41566, South Korea ⓘ ⓘ 59816109100; 57211287845 ⓘ bkim21@knu.ac.kr; hchoi21@knu.ac.kr; ⓘ RICERCHE DI MATEMATICA ⓘ RIC MAT ⓘ 0035-5038 1827-3491 74 2 SCIE MATHEMATICS, APPLIED;MATHEMATICS ⓘ 2024 1.1 22.3 0 2025-05-07 ⓘ 1 1 Finite local rings; Pseudo-valuation rings; Chain rings; Cyclic codes ⓘ VALUATION RINGS; CYCLIC CODES; OVERRINGS; DOMAINS; IDEALS ⓘ Chain rings; Cyclic codes; Finite local rings; Pseudo-valuation rings ⓘ ⓘ English 2025 2025-04 10.1007/s11587-024-00852-x ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ The TUITEK® patient support program improved caregiver-related behaviors on growth hormone treatment adherence ⓘ Background Recombinant human growth hormone (r-hGH) can improve or normalize growth outcomes in pediatric patients with growth hormone deficiency, but poor adherence to the treatment regimen limits treatment effectiveness. TUITEK (R) is a multicomponent patient support program (PSP) designed to deliver support aimed at behavior change that is personalized to the needs of individual caregivers and patients throughout the treatment care pathway. The aim was to assess the impact of the TUITEK (R) PSP on knowledge, beliefs and perceptions of adherence to r-hGH treatment in high-risk caregivers. Patients and methods A prospective pre-post research was conducted across the combined population of caregivers of patients with short stature receiving r-hGH treatment in the TUITEK (R) PSP in Argentina, South Korea, and Taiwan. Caregivers who were categorized as high-risk based on suboptimal knowledge, beliefs and perceptions of factors influencing adherence to r-hGH treatment (disease and treatment coherence, emotional burden, self-administration, and treatment-related anxiety) were included in the analysis. Results In total, data from 409 caregivers were available. Involvement in the TUITEK (R) PSP resulted in a statistically significant (p<0.0001) positive change for all factors. Improvements were reflected in the number of caregivers who moved from high- to low-risk at the end of the TUITEK (R) PSP. The overall changes were reflected in the changes observed when data were analyzed for individual countries separately. Conclusions The TUITEK (R) PSP successfully improved key caregiver-related behaviors that may negatively impact adherence to r-hGH treatment and might improve adherence and therefore clinical outcomes. ⓘ Koledova, Ekaterina; Su, Pen-Hua; Chen, Yen-Ju; Assefi, Aria; Debicki, Matias; Cooke, Debbie; Jheeta, Amrit; Jones, Alexander B.; Moon, Jung Eun ⓘ Merck Healthcare KGaA, Global Med Affairs Cardiometab & Endocrinol, Darmstadt, Germany; Chung Shan Med Univ, Sch Med, Taichung, Taiwan; Chung Shan Med Univ Hosp, Dept Pediat & Genet, Taichung, Taiwan; Merck Ltd, Med & Clin Affairs Dept, Taipei, Taiwan; Merck SA, Med Dept, Buenos Aires, Argentina; Merck SA, Patient Support Program, Buenos Aires, Argentina; Atlantis Hlth Ltd, London, England; Insci Commun, London, England; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Pediat, Daegu, South Korea ⓘ Assefi, Aria/KPB-4740-2024 ⓘ 8549887500; 7101814899; 59834486500; 6507868988; 58195856100; 35490418400; 57710153500; 59835327400; 57205770947 ⓘ ekaterina.koledova@merckgroup.com; ⓘ FRONTIERS IN ENDOCRINOLOGY ⓘ FRONT ENDOCRINOL ⓘ 1664-2392 16 SCIE ENDOCRINOLOGY & METABOLISM ⓘ 2024 4.6 22.3 N/A ⓘ 0 0 adherence behaviors; patient support program; recombinant human growth hormone; growth hormone deficiency; behavior change techniques ⓘ THERAPY ⓘ adherence behaviors; behavior change techniques; growth hormone deficiency; patient support program; recombinant human growth hormone ⓘ growth hormone; adult; anxiety; Article; care behavior; caregiver; female; follow up; health belief; health program; hormonal therapy; human; human experiment; knowledge; Likert scale; male; patient compliance; patient support program; perception; prospective study; questionnaire ⓘ English 2025 2025-04-28 10.3389/fendo.2025.1548558 ⓘ 바로가기 바로가기 바로가기 바로가기
