| ○ | ○ | Article | Fabrication luminescence and radiation shielding properties of Gd2O3-La2O3-ZnO-B2O3-Sm2O3 glasses | The purpose of developing high transparency radiation shielding materials and luminescence materials with stoichiometric ratio of xGd2O3:10La2O3:10ZnO:(79-x) B2O3: 1Sm2O3 where x = 0, 5, 10, 15, and 20 mol% using melt quenching technique. The physio-optical properties such as molar volume, density, concentration of rare-earth ions, polaron radius, inter-ionic radius, optical basicity, average distance between rare-earth ions, and optical packing density of the present glasses has been evaluated. The glass samples obtained show high density which is vital factor for radiation shielding. The absorption spectra show significant of bands Sm3+ ions. The FTIR results of Gd-La-Zn-B-Sm (Gd-1Sm) glass samples show signature borate BO3 and BO4 vibrational units in Gd-1Sm glass samples. The mu, mu m, HVL, TVL, and MFP were evaluated and showed that the values decrease with increasing X-ray energy whereas increase with an increase in Gd2O3 content suggesting their potential use in X-ray diagnosis regions. The HVL value was compared with commercial windows, concrete, Serpentine and X-ray windows and found that the glasses doped with 10 mol%, 15mol%, and 20 mol% Gd2O3 content showed better results than X-Ray windows at 10 kVp. The emission and excitation spectra of glass samples were studied and emission spectra show orange emission bands. The experimental lifetime analysis shows that the glass samples show decreasing trend from 1.161 to 1.128 ms with an increase in Gd3+ ions exhibiting single exponential nature. | Kaewjaeng, S.; Kothan, S.; Wantana, N.; Kim, H.

| ○ | ○ | Article | Fully flexible thermoelectric and piezoelectric hybrid generator based on a self-assembled multifunctional single composite film | Thermoelectric and piezoelectric hybrid generators (TPHGs) are attractive candidates for powering wearable body sensor networks continuously and permanently owing to their excellent access to human-generated energy. Herein, we propose a fully flexible single film-based TPHG comprising n-type Bi2Te2.7Se(0.3) particles and poly (vinylidene fluoride-co-trifluoroethylene). The hybrid generator was assembled through simple drop-casting and gravitational settling effect, for the first time. The film layer sedimented with the conductive thermoelectric particles simultaneously served as an electrode and a bottom substrate for piezoelectric energy harvesting. The fabricated device generated outputs of 1 mu A and 4 V at a temperature difference of 3 K and a bending displacement of 5 mm; these values indicate that the thermoelectric and piezoelectric effects were combined well without compromising the energy harvesting performance of each part. Furthermore, the fabricated device exhibited robust mechanical durability for similar to 5000 bending cycles; this result was better than those of previously reported flexible TPHGs (f-TPHGs). The proposed design concept for f-TPHGs can aid in the development of highperformance multisource energy harvesting devices for wearable sensors. | Kim, Seoha; Hyeon, Dong Yeol; Lee, Donghun; Bae, Jun Ho; Park, Kwi-Il | Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | Park, Kwiil/LKN-9445-2024; Kim, So-Young/JFS-7698-2023; Hyeon, Dong Yeol/HNR-5711-2023 | 57212495287; 57209099464; 59444729800; 36900467300; 35280874200 | kipark@knu.ac.kr; | MATERIALS TODAY PHYSICS | MATER TODAY PHYS | 2542-5293 | 35 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2023 | 10 | 8.7 | 1.21 | 2025-06-25 | 9 | 9 | Flexible; Piezoelectric; Thermoelectric; Hybrid generator; Energy harvesting | FACILE PREPARATION; ENERGY HARVESTER; HIGH-PERFORMANCE; PVDF | Energy harvesting; Flexible; Hybrid generator; Piezoelectric; Thermoelectric | Bismuth compounds; Body sensor networks; Electric generators; Fluorine compounds; Piezoelectric devices; Piezoelectricity; Selenium compounds; Tellurium compounds; Wearable sensors; Energy; Fabricated device; Flexible; Hybrid generator; Performance; Piezoelectric; Poly(vinylidene fluoride); Single composites; Thermoelectric; Trifluoroethylene; Energy harvesting | English | 2023 | 2023-06 | 10.1016/j.mtphys.2023.101103 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Green and low-carbon upcycling of ludwigite: Prepared shields against nuclear radiation hazards and shielding mechanism | The complex composition of ludwigite makes its comprehensive usage difficult. Given the rapid development of ores in nuclear shielding materials, ludwigite was proposed to prepare epoxy resin matrix nuclear shielding composites at room temperature, which could achieve green and low-carbon upcycling. The shielding perfor-mance of neutron and gamma-ray sources was evaluated using the 241Am-Be neutron source, the Co-60 gamma -ray source and the Evaluated Nuclear Data File (ENDF). Scanning electron microscopy was used to examine the microstructures. Increasing the ludwigite weight and thickness of the shielding composite increases the shielding percentage of the prepared composites. The prepared shielding composites have macroscopic cross-sections of 0.92-1.89 cm -1, which are comparable to SWX-201, which contains 5% boron. Boron absorption and hydrogen elastic scattering are the primary shielding mechanisms for neutron attenuation in 10- 11-10-6 MeV. The shielding composites' gamma-ray shielding performance is comparable to that of water and ordinary concrete. The work is significant not only for using ludwigite but also for the shielding mechanism analysis of complex multi-element composites. | Dong, Mengge; Zhou, Suying; Ge, Changcheng; Yang, He; Liu, Mao; Lakshminarayana, G.; Xue, Xiangxin | Northeastern Univ, Sch Met, Dept Resource & Environm, Shenyang 110819, Peoples R China; Key Lab Met Resources Recycling Sci, Shenyang 110819, Liaoning, Peoples R China; Engn & Technol Res Ctr Boron Resource Comprehens D, Shenyang 110819, Peoples R China; Liaoning Key Lab Ecol Comprehens Utilizat Boron Re, Shenyang 110819, Peoples R China; Kyungpook Natl Univ, Intelligent Construct Automat Ctr, 80 Daehak Ro, Daegu 41566, South Korea | ; Ge, Changcheng/GVS-6182-2022; DONG, Mengge/AEN-2933-2022; liu, mao/AAO-7073-2020 | 56082379700; 57225878696; 58159916700; 56901966100; 55755296400; 57194637883; 57808590800 | mg_dong@163.com;xuexx@mail.neu.edu.cn; | RADIATION PHYSICS AND CHEMISTRY | RADIAT PHYS CHEM | 0969-806X | 1879-0895 | 208 | SCIE | CHEMISTRY, PHYSICAL;NUCLEAR SCIENCE & TECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2023 | 2.8 | 8.7 | 1.11 | 2025-06-25 | 5 | 5 | Ludwigite; Epoxy resin; Neutron; Shielding mechanism | NEUTRON-CAPTURE THERAPY; ATTENUATION COEFFICIENTS; GAMMA-IRRADIATION; BORON; ORES; COMPOSITES; COLEMANITE; NUMBER; RAYS; SLAG | Epoxy resin; Ludwigite; Neutron; Shielding mechanism | Carbon; Epoxy resins; Gamma rays; Neutron irradiation; Neutron sources; Radiation shielding; Scanning electron microscopy; americium 241; beryllium; boron; boron derivative; cobalt 60; concrete; epoxy resin; hydrogen; ludwigite; unclassified drug; water; Complex compositions; Gamma ray sources; Green carbons; Low carbon; Ludwigite; Nuclear radiations; Nuclear shielding; Shielding composite; Shielding mechanism; Shielding performance; Article; chemical composition; chemical structure; gamma radiation; green and low carbon upcycling; green chemistry; neutron radiation; radiation hazard; room temperature; scanning electron microscopy; thickness; waste management; weight; Neutrons | English | 2023 | 2023-07 | 10.1016/j.radphyschem.2023.110931 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Influence of Eu3+dopant on lithium barium gadolinium phosphate glass properties for orange-reddish photonic devices | The Eu3+-doped lithium barium gadolinium phosphate glasses were prepared using the conventional melt-quenching method with different concentrations of Eu2O3 and Gd2O3. The physical characteristics were deter-mined by refractive index, density, molar volume, oxygen packing volume, and oxidation states. Moreover, the optical characteristics were investigated via photoluminescence spectroscopy (PL), UV-vis spectroscopy, Radi-oluminescence (RL), and decay time. It was found that the Gd2O3 concentration of 12 mol% was the optimum composition for further investigations of the Eu2O3 doping concentration optimization. The emission spectra of PL and RL showed the strongest intensity of orange-reddish emission (lambda Ex = 394 nm) when the Eu2O3 concen-tration was at 0.3 mol% corresponding to energy transition from 5D0 -> 7F0,1,2,3,4. The oxidation state of Eu3+ ions due to the formation of non-bridging oxygens (NBO) in the glass network was confirmed by using X-ray Ab-sorption Near Edge Spectroscopy (XANE). Furthermore, the high transparency and fast decay time in the range of 2.4-2.8 ms displayed the potential to improve laser and radiation detector performances. | Kamonpha, P.; Manyum, P.; Chanthima, N.; Tariwong, Y.; Triamnak, N.; Yimnirun, R.; Rujirawat, S.; Kidkhunthod, P.; Tanthanuch, W.; Kothan, S.; Kim, H.

| ○ | ○ | Article | Influence of Gd³⁺ on structural and luminescence properties of new Eu³⁺-doped borate glass for photonics material | The Gd2O3-La2O3-ZnO-B2O3-Eu2O3 glasses with different Gd2O3 concentration (Gd:LaZnBEu) were studied in the physical, structural, optical and luminescence properties. The density and refractive index of glass increased with addition of Gd2O3 content. The FTIR spectra demonstrated the BO3 and BO4 borate complexes as the main construction in glass those were more disturbed by Gd2O3 increasing. The BO4/BO3 and bridging/non-bridging oxygen ratio, observed from XPS, changed by following the Gd2O3 concentration whose 10 mol% owned the highest values of both ratios. In the absorption spectra, glasses absorbed some photons in UV - NIR region. The excitation by O2--> Eu3+ charge transfer (240 nm), Gd3+-> Eu3+ energy transfer (275 nm) and direct Eu3+ excitation (394 nm) caused the strongest Eu3+ photoluminescence at 613 nm (5D0 -> 7F2). The glass with 5 mol %-Gd2O3, that possessed the optimum Eu3+ local site, exhibited the highest absorbance and photo-/radio -luminescence intensity. The CIE 1931 and UV lamp excitation revealed the strong reddish-orange emission of glasses. The photoluminescence decay time of Eu3+ in glasses were between 1.6 and 2.1 ms and decreased with added Gd2O3 amount. The Gd:LaZnBEu glasses have a potential for LED, laser, display, and X-ray detection devices with integration mode. | Wantana, N.; Kaewnuam, E.; Chanlek, N.; Kim, H.

| ○ | ○ | Article | Investigation on luminescence properties and XANES of dysprosium ion doped borophosphate glasses | In this research, melt quenching was used to prepare Dy3+ ion doped alkaline borophosphate glasses. According to the XANES measurement, Dy ions in glass show +3 oxidation state, identical to the standard Dy2O3 powder. Glasses were measured for density (rho), molar volume (Vm), and refractive index (n). The absorption peaks, which are assigned to transitions from the ground state 6H15/2 to higher energy levels of Dy3+ ion in glass matrix. Four prominent emission bands were observed in luminescence spectra, which correspond to the 4F9/2 -> 6HJ (J = 15/2, 13/2, 11/2, 9/2) transitions. The Judd-Ofelt (J-O) intensity parameters follow the trend as omega 2>omega 6>omega 4 of the PBLAGdDy1.0. For the stimulated emission cross-section and branching ratio (>0.5), 4F9/2 -> 6H13/2 transition was found to be higher than other transitions. Because the decay curves of glasses with different concentrations of Dy3+ ion were found to be non-exponential, these glasses were calculated using the Inokuti-Hirayama (I-H) model. The obtained photoluminescence and decay times spectra primarily showed energy transfer effects from Gd3+ to Dy3+ ions and the calculated values of energy transfer efficiency (eta) found that the values increased, which confirms energy transfer from Gd3+ to Dy3+ ions. From this study, the current glasses could be useful in the applications of solid-state lasers, LEDs, and scintillation materials. | Kiwsakunkran, N.; Chanthima, N.; Kim, H.

| ○ | ○ | Article | Local structure and energy transfer of Gd3+to Dy3+in phosphate-based glasses | The phosphate-based glasses doped with Gd3+ and Dy3+ ions were fabricated by melt quenching at 1200 degrees C. The physical, structural, and luminescence properties that would suggest they are potential candidates for scintil-lating materials have been examined. The density and molar volume of glasses increase with increasing Gd3+ concentration. The absorption peaks indicate the Dy3+ energy transition from the 6H15/2 ground state to several excited states such as 6P7/2 (350 nm), 6P3/2 (364 nm), 6F7/2 (387 nm), 6G11/2 (426 nm), 6I15/2 (452 nm), 6F5/2 (807 nm), 6F7/2 (906 nm), 6F9/2 (1100 nm), 6H9/2 (1285 nm), and 6H11/2 (1697 nm), respectively. According to the findings, when compared to a commercially available BGO crystal, the highest value of x-ray luminescence spectrum intensity was observed at 17 mol% of Gd2O3, with 15.42% of the integral scintillation efficiency. However, the photoluminescence spectra show the maximum value at 13 mol% of Gd2O3 content with excited at 275 nm and 350 nm, while the decay time (tau) tends to decrease with increasing Gd2O3 content. Interestingly, the local structure study was conducted through XANES and EXAFS analysis to understand the local environment of Gd and Dy atoms. The XANES result indicated that the oxidation states of the Gd and Dy ions in the sample glass were +3. The EXAFS fitting parameters showed Debye-Waller factors (sigma 2) of 17 mol% of Gd2O3 as the highest value that represents a more asymmetric environment around Gd/Dy. Moreover, the EXAFS fitting indicates a short distance of Gd-Gd at 13 mol% Gd2O3 content is indicative of their efficient internal energy transfer be-tween Gd-Gd. | Yodkantee, D.; Prasatkhetragarn, A.; Kidkhunthod, P.; Kothan, S.; Yimnirun, R.; Kim, H.

| ○ | ○ | Article | Luminescence characteristics of Ce3+doped multicomponent lithium fluorophosphate glasses | We have used the melt quenching technique to fabricate glass samples with the composition 20Li2O-10AlF3- 2.5R-(57-x)P2O5-10Gd2O3-0.5CeF3 (R = 0, NaF, KF). These glasses were synthesized and their density, molar volume, refractive index, FTIR (Fourier-transform infrared spectroscopy) spectra, transmittance spectra, decay time analysis, and photo and radioluminescence properties were reported. Surface-sensitive techniques such as X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge spectroscopy (XANES) were investi-gated. As a result, the FTIR spectra of these glasses break the Q2 tetrahedral sites of the phosphate structure when adding alkali fluoride. UV emission at-337 nm was observed at-302 nm excitation. In XPS spectra, phosphorus oxidation states (P2p) were detected. The investigation of X-ray Absorption Near-Edge Structure (XANES) of Ce LIII-edge was shown at-5.726 keV and confirmed the presence of Ce3+ and Ce4+ was shown at-5.731 keV and-5.738 keV. The comparison of the Ce3+ and Ce4+ ratios by fitting the energy range in the XANES spectrum may confirm the luminescence characteristic of the glass. A full energy peak was observed in the pulse height spectra of a 241Am alpha-ray irradiation in the PLGdAfKfCe0.5 glass, and the calculated light yields of PLGdAfKfCe0.5 was 49 Ph/MeV under alpha-ray. From the results can be concluded that the PLGdAfKfCe0.5 glass showed promising prop-erties as a scintillator material. | Sarumaha, C.

| ○ | ○ | Article | Measurement of neutron capture cross sections for the 174Yb(n,γ)175Yb reaction at thermal and epithermal energies | Herein, we measured the thermal neutron capture cross section (sigma 0) and resonance integral (I0) of the 174Yb (n,gamma)175Yb reaction relative to those of the reference reaction 197Au(n,gamma)198Au. Measurements were conducted based on the activation method using pulsed neutrons combined with the Cd ratio method and offline gamma-ray spectrometry. Pulsed neutrons were generated on a 100 MeV electron linac of the Pohang Accelerator Labora-tory, Korea. Yb samples and Au monitors were irradiated with and without a 0.5 mm Cd cover to absorb thermal neutrons. The neutron flux was determined via the 115In(n,gamma)116mIn reaction. The induced activities of the re-action products were measured using a gamma spectrometer based on a well-calibrated HPGe detector. For the 174Yb(n,gamma)175Yb reaction, the thermal neutron capture cross section and resonance integral cross-section were obtained as sigma 0,Yb = 70.5 +/- 4.2 b and I0,Yb = 54.1 +/- 4.2 b, relative to the corresponding values of sigma 0,Au = 98.65 +/- 0.09 b and I0,Au = 1550 +/- 28 b for the 197Au(n,gamma)198Au reference reaction. The obtained results were compared with the measured and evaluated data. | Hien, Nguyen Thi; Van Do, Nguyen; Kim, Guinyun; Naik, Haladhara; Khue, Pham Duc | Kyungpook Natl Univ, Dept Phys, Daegu, South Korea; Duy Tan Univ, Inst Theoret & Appl Res, Hanoi 100000, Vietnam; Duy Tan Univ, Fac Nat Sci, Da Nang 550000, Vietnam; Vietnam Acad Sci & Technol, Inst Phys, 10 Dao Tan, Hanoi, Vietnam; Bhabha Atom Res Ctr, Radiochem Div, Mumbai 400085, India; VINATOM, Inst Nucl Sci & Technol, 179 Hoang Quoc Viet, Hanoi, Vietnam | Vân-Anh, Nguyen/ITT-3241-2023 | 59638495100; 20533839400; 35313854400; 7005890232; 14063183900 | gnkim@knu.ac.kr; | RADIATION PHYSICS AND CHEMISTRY | RADIAT PHYS CHEM | 0969-806X | 1879-0895 | 205 | SCIE | CHEMISTRY, PHYSICAL;NUCLEAR SCIENCE & TECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2023 | 2.8 | 8.7 | 0.89 | 2025-06-25 | 3 | 4 | Neutron capture cross section; Neutron activation method; 174Yb(n?)175Yb reaction; 197Au(n?)198Au monitor reaction; HPGe detector; Off-line ?-ray spectrometry | NUCLEAR-DATA; YB-174(N,GAMMA)YB-175 REACTION; ACTIVATION; INTEGRALS; SPECTRUM; SCIENCE; YB-175 | <sup>174</sup>Yb(n,γ)<sup>175</sup>Yb reaction; <sup>197</sup>Au(n,γ)<sup>198</sup>Au monitor reaction; HPGe detector; Neutron activation method; Neutron capture cross section; Off-line γ-ray spectrometry | Gamma ray spectrometers; Germanium compounds; Gold; Spectrometry; cadmium; gold; gold 198; unclassified drug; ytterbium; ytterbium 174; ytterbium 175; 174yb(n,γ)175yb reaction; 197au(n,γ)198au monitor reaction; Activation method; HPGe detectors; Monitor reactions; Neutron activation; Neutron activation method; Neutron capture cross section; Off-line γ-ray spectrometry; Thermal neutron capture; Article; calibration; comparative study; controlled study; electron; energy; gamma spectrometry; irradiation; neutron capture therapy; radiation measurement; Chemical activation | English | 2023 | 2023-04 | 10.1016/j.radphyschem.2022.110738 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

Measurements were performed by means of the activation method in combination with off-line gamma-ray spectrometry. The induced activity of radionuclides was measured with a high-purity germanium (HPGe) detector and necessary corrections for gamma-ray interferences were made. The integrated cross section of the studied reactions was measured relative to that of the monitor reaction 27Al(gamma,2pn)24Na. Current results are compared with theoretical predictions using the TALYS-1.9 statistical nuclear model code. Calculations were performed using six different level density models in combination with eight gamma-strength functions to determine which combinations best fit the experimental results. The present results are measured for the first time. | Van Do, Nguyen; Luan, Nguyen Thanh; Xuan, Nguyen Thi; Thanh, Kim Tien; Van Loat, Bui; Hien, Nguyen Thi; Kim, Guinyun | Duy Tan Univ, Inst Theoret & Appl Res, Hanoi 100000, Vietnam; Duy Tan Univ, Fac Nat Sci, Da Nang 550000, Vietnam; Vietnam Acad Sci & Technol, Inst Phys, 10 Dao Tan, Hanoi, Vietnam; Kyungpook Natl Univ, Dept Phys, Daegu 702701, South Korea; VAST, Grad Sch Sci & Technol, 18 Hoang Quoc Viet, Hanoi, Vietnam; VNU Univ Sci, Fac Phys, Dept Nucl Phys, 334 Nguyen Trai, Hanoi, Vietnam | Nguyen, Ngoc/AAO-7237-2020; Thanh Duong, Nguyen/AGY-4248-2022 | 16748257500; 57210576969; 57901826000; 23983320200; 25936922600; 59638495100; 35313854400 | gnkim@knu.ac.kr; | RADIATION PHYSICS AND CHEMISTRY | RADIAT PHYS CHEM | 0969-806X | 1879-0895 | 203 | SCIE | CHEMISTRY, PHYSICAL;NUCLEAR SCIENCE & TECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2023 | 2.8 | 8.7 | 0.44 | 2025-06-25 | 0 | 2 | Photonuclear reaction; Integrated cross section; Activation method; 109mPd; 109gPd; 108mRh; TALYS-1; 9 code | COINCIDENCE SUMMING CORRECTIONS; ISOMERIC-YIELD RATIOS; PHOTONUCLEAR REACTIONS; GAMMA; EXCITATION; MODELS | <sup>108m</sup>Rh; <sup>109g</sup>Pd; <sup>109m</sup>Pd; Activation method; Integrated cross section; Photonuclear reaction; TALYS-1.9 code | Chemical activation; Codes (symbols); Gamma ray spectrometers; Phosphorus compounds; aluminum; palladium; rhodium; sodium 24; 108mrh; 109gpd; 109mpd; Activation method; Energy ranges; Integrated cross sections; Measurements of; Pd(110); Photonuclear reaction; TALYS-1.9 code; Article; brems radiation; calculation; controlled study; density; electron beam; energy; gamma radiation; gamma spectrometry; measurement; measurement accuracy; prediction; time; validity; waiting time; Germanium compounds | English | 2023 | 2023-02 | 10.1016/j.radphyschem.2022.110598 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Personalized Antiviral Drug Selection in Patients With Chronic Hepatitis B Using a Machine Learning Model: A Multinational Study | INTRODUCTION: Tenofovir disoproxil fumarate (TDF) is reportedly superior or at least comparable to entecavir (ETV) for the prevention of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B; however, it has distinct long-term renal and bone toxicities. This study aimed to develop and validate a machine learning model (designated as Prediction of Liver cancer using Artificial intelligence-driven model for Network-antiviral Selection for hepatitis B [PLAN-S]) to predict an individualized risk of HCC during ETV or TDF therapy.METHODS: This multinational study included 13,970 patients with chronic hepatitis B. The derivation (n = 6,790), Korean validation (n = 4,543), and Hong Kong-Taiwan validation cohorts (n = 2,637) were established. Patients were classified as the TDF-superior group when a PLAN-S-predicted HCC risk under ETV treatment is greater than under TDF treatment, and the others were defined as the TDF-nonsuperior group.RESULTS: The PLAN-S model was derived using 8 variables and generated a c-index between 0.67 and 0.78 for each cohort. The TDF-superior group included a higher proportion of male patients and patients with cirrhosis than the TDF-nonsuperior group. In the derivation, Korean validation, and Hong Kong-Taiwan validation cohorts, 65.3%, 63.5%, and 76.4% of patients were classified as the TDF-superior group, respectively. In the TDF-superior group of each cohort, TDF was associated with a significantly lower risk of HCC than ETV (hazard ratio = 0.60-0.73, all P 0.1). [GRAPHICS] .DISCUSSION: Considering the individual HCC risk predicted by PLAN-S and the potential TDF-related toxicities, TDF and ETV treatment may be recommended for the TDF-superior and TDF-nonsuperior groups, respectively. | Hur, Moon Haeng;

| ○ | ○ | Article | Response-Guided Therapy With Cefotaxime, Ceftriaxone, or Ciprofloxacin for Spontaneous Bacterial Peritonitis: A Randomized Trial A Validation Study of 2021 AASLD Practice Guidance for SBP | INTRODUCTION:For the treatment of spontaneous bacterial peritonitis (SBP), cefotaxime, ceftriaxone, and ciprofloxacin were used as first-line agents. However, considering the increasing rate of antibiotic resistance, it is unclear which of these drugs can be initially recommended. This study aimed to compare the current efficacy of the 3 antibiotics, namely cefotaxime, ceftriaxone, and ciprofloxacin, for the treatment of SBP in patients with cirrhosis with ascites, when guided by therapeutic responses.METHODS:This study was a multicenter, prospective, randomized controlled trial. The inclusion criteria were 16- to 75-year-old patients with liver cirrhosis with ascites, having polymorphonuclear cell count of >250/mm(3). We performed a follow-up paracentesis at 48 hours to decide continuing or changing the assigned antibiotics and then assessed the resolution rates at 120 and 168 hours of treatment.RESULTS:A total of 261 patients with cirrhosis who developed SBP were enrolled. Most of the patients were diagnosed as those with SBP within 48 hours of admission. The resolution rates at 120 hours, which is the primary endpoint, were 67.8%, 77.0%, and 73.6% in the cefotaxime, ceftriaxone, and ciprofloxacin groups, respectively (P = 0.388), by intension-to-treat analysis. The 1-month mortality was similar among the groups (P = 0.770). The model for end-stage liver disease score and the SBP resolution were significant factors for survival.CONCLUSION:The efficacy of empirical antibiotics, such as cefotaxime, ceftriaxone, and ciprofloxacin, against SBP was not significantly different. In addition, these antibiotics administered based on response-guided therapy were still efficacious as initial treatment for SBP, especially in those with community-acquired infections. | Yim, Hyung Joon; Kim, Tae Hyung; Suh, Sang Jun; Yim, Sun Young; Jung, Young Kul; Seo, Yeon Seok; Kang, Seong Hee; Kim, Moon Young; Baik, Soon Koo; Kim, Hong Soo; Kim, Young Seok; Park, Soo Young; Kim, Byung Ik; Park, Jun Yong; Heo, Jeong; Sohn, Joo Hyun; Heo, Nae-Yun; Han, Kwang-Hyub; Um, Soon Ho | Korea Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Wonju Coll Med, Dept Internal Med, Wonju, South Korea; Inje Univ, Coll Med, Seoul, South Korea; Soonchunhyang Univ, Coll Med, Dept Internal Med, Asan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Sungkyunkwan Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Pusan Natl Univ, Coll Med, Dept Internal Med, Busan, South Korea; Hanyang Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Inje Univ, Haeundae Paik Hosp, Coll Med, Dept Internal Med, Busan, South Korea | Yim, Sun/AAX-8128-2020; Kim, Young/T-8521-2019; Kim, Han/C-4709-2011; Heo, Jeong/MHQ-1390-2025; Park, Jun/HPH-3570-2023; Kim, Yangdo/AAC-2495-2021; Heo, Nae-Yun/LUY-9667-2024 | 7005664934; 57755913500; 25723856600; 57217559329; 25626113500; 35234912400; 55850927200; 55545239100; 19833516800; 57205055260; 57207444475; 57191674344; 24477301500; 47861376300; 8422238800; 57222479854; 14022750600; 7402963689; 57416815200 | lacid@korea.ac.kr;mothpickle@naver.com;eug203@naver.com;free93cool@gmail.com;drseo@korea.ac.kr;shkang0114@gmail.com;drkimmy@yonsei.ac.kr;baiksk@yonsei.ac.kr;khskhs@sch.ac.kr;liverkys@schmc.ac.kr;psyoung0419@gmail.com;bik.kim@samsung.com;DRPJY@yuhs.ac;jheo@pusan.ac.kr;sonjh@hanyang.ac.kr;H00175@paik.ac.kr;gihankhys@yuhs.ac;umsh@korea.ac.kr;gudwns21@korea.ac.kr; | AMERICAN JOURNAL OF GASTROENTEROLOGY | AM J GASTROENTEROL | 0002-9270 | 1572-0241 | 118 | 4 | SCIE | GASTROENTEROLOGY & HEPATOLOGY | 2023 | 8.5 | 8.7 | 1.29 | 2025-06-25 | 9 | 9 | ASCITES; empirical treatment; antibiotics; liver cirrhosis; comparison | ORAL CIPROFLOXACIN; CIRRHOSIS; INFECTIONS; NORFLOXACIN; MANAGEMENT; RESISTANCE | antibiotics; ASCITES; comparison; empirical treatment; liver cirrhosis | Adolescent; Adult; Aged; Anti-Bacterial Agents; Ascites; Bacterial Infections; Cefotaxime; Ceftriaxone; Ciprofloxacin; End Stage Liver Disease; Humans; Liver Cirrhosis; Middle Aged; Peritonitis; Prospective Studies; Severity of Illness Index; Young Adult; alanine aminotransferase; bilirubin; cefotaxime; ceftriaxone; ciprofloxacin; creatinine; hemoglobin; norfloxacin; piperacillin plus tazobactam; antiinfective agent; cefotaxime; ceftriaxone; ciprofloxacin; abdominal infection; abdominal pain; acute kidney failure; antibiotic resistance; antibiotic therapy; Article; bacterial peritonitis; cell count; Child Pugh score; clinical trial; colony forming unit; community acquired infection; controlled study; end stage liver disease; fever; follow up; gastrointestinal hemorrhage; hematocrit; hemoglobin blood level; hospitalization; human; human cell; leukocyte count; leukocytosis; liver cirrhosis; major clinical study; Model For End Stage Liver Disease Score; mortality; multicenter study; neutrophil count; overall survival; paracentesis; platelet count; polymorphonuclear cell; prospective study; prothrombin time; randomized controlled trial; adolescent; adult; aged; ascites; bacterial infection; complication; end stage liver disease; liver cirrhosis; microbiology; middle aged; peritonitis; severity of illness index; young adult | English | 2023 | 2023-04 | 10.14309/ajg.0000000000002126 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Role of the Gd2O3 increment on the cerium oxidation state and luminescence behavior in the CeF3 doped silicoborate glass | This study aimed to investigate the effect of Gd2O3 on the cerium oxidation state and studied their luminescence in the silicoborate glass. Glass samples of a silicoborate glass containing cerium fluoride were prepared by doping the glass with varying amounts of Gd2O3 in the chemical formula xGd2O3: 40Na2O: 5SiO2: (54.5)B2O3: 0.5CeF3 (x = 0.0, 2.5, 5.0, 7.5, and 10.0 mol%). Density and refractive index tend to increase with increasing Gd2O3 content, whereas molar volume decreases. High-resolution XPS spectra confirm the chemical composition in the glass structure and found that the B1s and O1s regions illustrated more BO4 and bridging oxygen, respectively. X-ray absorption near edge structure (XANES) at the Ce LIII-edge was used to investigate the proportion between trivalent cerium (Ce3+) and tetravalent cerium (Ce4+). The ratio of Ce3+/Ce4+ decreased with the addition of Gd2O3. A higher concentration of Gd2O3 content showed more Ce4+ related to the reduction of photo-luminescence and X-ray-induced luminescence spectra. Alpha-induced luminescence was used to calculate the light yield of the 7.5Gd:0.5CeF glass. Decay time was measured by pulsed light sources at 286 nm and X-ray excitation. | Intachai, N.; Wantana, N.; Kaewjaeng, S.; Kothan, S.; Kidkhunthod, P.; Chanlek, N.; Kim, H.

| ○ | Article | Structural and luminescence investigations of Gd3+ - Er3+ doped in lithium aluminum borate glasses using XANES and EXAFS techniques | The typical melt quenching technique was utilized to produce a possibly unique series of Gd3+ and Er3+ dual doped borate glasses with a composition of 25Li2O–5Al2O3-XGd2O3-(69.0-X)B2O3-1.0Er2O3. The amorphous nature and information on chemical bindings of the materials were validated by using fundamental characterization techniques such as X-ray diffraction, Fourier transform infrared, X-ray absorption near-edge structure, and optical screening to identify their features (absorption, excitation, and emission). The refractive index of the glasses improves from 1.5487 to 1.628 as the concentration of Gd2O3 increases. The optical absorption spectra of Er3+ doped glasses were measured from the ultraviolet (UV) through the visible (Vis) and near infrared (NIR) ranges with varying Gd2O3 concentrations in order to determine their optical properties. This luminescence was found to be predominant in photoluminescence spectra, which were obtained at an optimum doping Gd2O3 concentration of 7.5 mol%. The impact of Er3+ doping was assessed through photoluminescence, which exhibited a broad, intense NIR band at 1537 nm ascribed to the 4I13/2 → 4I15/2 transition of Er3+ ions at λEx = 486, 526, 651, and 978 nm excitation, which exhibits outstanding increased intensity with the Er3+ concentration until it reaches 1.0 mol %. A look at visible and near-infrared optical, it is observed that LAGd7.5BEr1.0 glass is a more potential candidate for photonic devices. © 2023 | Manyum, P.; Rittisut, W.; Mool-am-kha, P.; Ekwongsa, C.; Wantana, N.; Ruangtaweep, Y.; Popanao, M.; Rujirawat, S.; Yimnirun, R.; Kidkhunthod, P.; Prasatkhetragarn, A.; Kothan, S.; Kim, H.J.; Kaewkhao, J. | School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasama, 30000, Thailand; School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasama, 30000, Thailand; Construction Materials Group, Engineering Materials Division, Department of Science Service, Ministry of Higher Education, Science, Research and Innovation, Bangkok, 10400, Thailand; School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasama, 30000, Thailand; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand; School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasama, 30000, Thailand; Synchrotron Light Research Institute (Public Organization), 111 University Avenue, Muang District, Nakhon Ratchasama, 30000, Thailand; School of Energy Science and Engineering, Vidyasirimedhi Institute of Science and Technology VISTEC, Wangchan, Rayong, 21210, Thailand, Research Network of NANOTEC-VISTEC on Nanotechnology for Energy, Vidyasirimedhi Institute of Science and TECHNOLOGY VISTEC, Wangchan, Rayong, 21210, Thailand; Synchrotron Light Research Institute (Public Organization), 111 University Avenue, Muang District, Nakhon Ratchasama, 30000, Thailand; Applied Science Program, School of Science, University of Phayao, Phayao, 56000, Thailand; Center of Radiation Research and Medical Imaging, Department of Radiologic Technology, Faculty of Associated Medical Sciences, Chiang Mai University, Chiang Mai, 50200, Thailand; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand | 6506891657; 57208675448; 57223232295; 57205302241; 56267058700; 37108588700; 58078247100; 6603107856; 24504594000; 35272197100; 23098474100; 6507017165; 59051568100; 23974520300 | pmanyum@sut.ac.th;jakrapong@webmail.npru.ac.th; | Radiation Physics and Chemistry | RADIAT PHYS CHEM | 0969-806X | 1879-0895 | 206 | SCIE | CHEMISTRY, PHYSICAL;NUCLEAR SCIENCE & TECHNOLOGY;PHYSICS, ATOMIC, MOLECULAR & CHEMICAL | 2023 | 2.8 | 8.7 | 1.11 | 2025-06-25 | 5 | Gd<sup>3+</sup> and Er<sup>3+</sup> dual doped; Melt quenching technique; Photoluminescence | Aluminum compounds; Erbium compounds; Gadolinium compounds; Gallium compounds; Glass; Infrared devices; Light absorption; Lithium compounds; Photonic devices; Quenching; Refractive index; X ray absorption; aluminum; boric acid; erbium; gadolinium; glass; lithium; Borate glass; Characterization techniques; Chemical binding; Dual doped; EXAFS; Gd3+ and er3+ dual doped; Melt quenching techniques; Visible and near infrared; X- ray diffractions; XANES; absorption; absorption spectroscopy; Article; excitation; extended X ray absorption fine structure spectroscopy; Fourier transform infrared spectroscopy; luminescence; near infrared spectroscopy; photoluminescence; refraction index; ultraviolet radiation; ultraviolet visible spectroscopy; X ray absorption near edge structure spectroscopy; X ray diffraction; Photoluminescence | English | Final | 2023 | 10.1016/j.radphyschem.2023.110801 | 바로가기 | 바로가기 | 바로가기 |
