| ○ | ○ | Article | Greater numbers and sizes of muscle bundles in the breast and leg muscles of broilers compared to layer chickens | Meat-type (broiler) and egg-type (layer) chickens were bred by intensive selection over the years, resulting in more numbers and larger sizes of myofibers. Although the characteristics are important parameters in muscle growth and meat quality, muscle bundle characteristics have not been studied in poultry. Therefore, this study aimed to compare the histological characteristics of myofibers and muscle bundles in muscles between male broiler (Ross broiler breed) chickens and layer (Hy-Line) chickens. Chicken muscles, pectoralis major (PM) and gastrocnemius (GM), were sampled at the age of 49 days and stained to analyze histological characteristics. Expectedly, body weights (BWs) and weights of PM and GM muscles in 49-day-old broilers were significantly heavier than those in layers. Within PM, broilers exhibited greater number and cross-sectional area (CSA) of myofibers than layers (3.3- and 3.3-fold, respectively). The total number and CSA of PM muscle bundles were approximately 1.5 and 6.6 times greater, respectively, in broilers than layers. Moreover, broilers exhibited 2 times greater number of myofibers per bundle of PM muscle than layers. Within GM, myofiber number and CSA were 2.3- and 2.4-fold greater, respectively, in broilers than layers. In addition, the total number of muscle bundles and bundle CSA were 2.5- and 2.1-fold greater, respectively, in broilers than in the layers. The novel findings of the current study provide evidence that greater muscle mass of broilers occurs by both hyperplasia and hypertrophy of muscle bundles and myofibers. | Lee, Boin; Kim, Dong-Hwan; Lee, Joonbum; Cressman, Michael D.; Choi, Young Min; Lee, Kichoon | Ohio State Univ, Dept Anim Sci, Columbus, OH 43210 USA; Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju Si, Gyeongsangbuk D, South Korea | Kim, Donghwan/LRC-0840-2024; Lee, Kichoon/G-2234-2012 | 57218130871; 56621562800; 57194466213; 36484215800; 57226673843; 14123395400 | lee.2626@osu.edu; | FRONTIERS IN PHYSIOLOGY | FRONT PHYSIOL | 1664-042X | 14 | SCIE | PHYSIOLOGY | 2023 | 3.2 | 27.6 | 0.81 | 2025-06-25 | 5 | 5 | broiler; layer; muscle hyperplasia; muscle hypertrophy; muscle bundle | FIBER CHARACTERISTICS; QUAIL; BREEDER | broiler; layer; muscle bundle; muscle hyperplasia; muscle hypertrophy | animal experiment; animal tissue; article; Article; body regions; breast; breast muscle; breed; broiler; controlled study; Gallus gallus; gastrocnemius muscle; histology; histopathology; leg muscle; male; muscle growth; muscle mass; nonhuman; pectoralis major muscle; poultry; rooster | English | 2023 | 2023-10-09 | 10.3389/fphys.2023.1285938 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Observation of reinforcing fibers in concrete upon bending failure by X-ray computed tomographic imaging | This study presents the visually observed behavior of fibers embedded in concrete samples that were subjected to a flexural bending test. Three types of fibers such as macro polypropylene, macro polyethylene, and the hybrid of steel and polyvinyl alcohol were mixed with cement by a designated mix ratio to prepare a total of nine specimens of each. The bending test was conducted by following ASTM C1609 with a net deflection of 2, 4, and 7 mm. The X-ray computed tomography (XCT) was carried out for 7 mm-deflection specimens. The original XCT images were post-processed to denoise the beam-hardening effect. Then, fiber, crack, and void were semi-manually segmented. The hybrid specimen showed the highest toughness compared to the other two types. Debonding based on 2D XCT sliced images was commonly observed for all three groups. The cement matrix near the crack surface often involved partially localized breakage in conjunction with debonding. The pullout was predominant for steel fibers that were partially slipped toward the crack. Crack bridging and rupture were not found presumably due to the image resolution and the level of energy dissipation for poly-fibers, while the XCT imaging was advantageous in evaluating the distribution and behavior of various fibers upon bending for fiber-reinforced concrete beam elements. | Lim, Seok Yong; Youm, Kwang Soo; Kim, Kwang Yeom; Byun, Yong - Hoon; Ju, Young K.; Yun, Tae Sup | Yonsei Univ, Sch Civil & Environm Engn, 50 Yonsei Ro, Seoul 03722, South Korea; GS Construct & Engn, 33 Jong Ro, Seoul 03159, South Korea; Korea Maritime & Ocean Univ, Dept Energy & Resources Engn, Taejong ro, Pusan 49112, South Korea; Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, 80 Daehak-ro, Daegu 41566, South Korea; Korea Univ, Sch Civil Environm & Architectural Engn, 145 Anam Ro, Seoul 02841, South Korea | Yun, Tae/G-7988-2012; Byun, Yong-Hoon/JKI-8441-2023; Kim, Kwang/ABG-4833-2020 | 57437907500; 23062341400; 54179503800; 42761048000; 8505936200; 13805250900 | seokyong@yonsei.ac.kr;ksyoum@gsenc.com;kykim@kmou.ac.kr;yhbyun@knu.ac.kr;tallsite@korea.ac.kr;taesup@yonsei.ac.kr; | COMPUTERS AND CONCRETE | COMPUT CONCRETE | 1598-8198 | 1598-818X | 31 | 5 | SCIE | COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, CHARACTERIZATION & TESTING | 2023 | 2.9 | 27.6 | 0 | 2025-06-25 | 0 | 0 | debonding; fiber-matrix mechanism; fiber-reinforced concrete; pullout; third-point loading test; X-ray computed tomography | PULLOUT BEHAVIOR; STEEL FIBERS; FLEXURAL BEHAVIOR; BOND SLIP; STRENGTH; DURABILITY; MATRIX; MECHANISMS; FRACTURE; CEMENT | debonding; fiber-matrix mechanism; fiber-reinforced concrete; pullout; third-point loading test; X-ray computed tomography | Cements; Computerized tomography; Concrete beams and girders; Energy dissipation; Failure (mechanical); Image resolution; Polypropylenes; Reinforced concrete; Steel fibers; Fiber matrix; Fiber-matrix mechanism; Fiber-reinforced concretes; Loading tests; Pullout; Reinforcing fibres; Third-point loading; Third-point loading test; X-ray computed; X-ray computed tomography; Debonding | English | 2023 | 2023-05 | 10.12989/cac.2023.31.5.433 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Radiative cooling system integrated with heat sink for the thermal management of photovoltaic modules under extreme climate conditions | Suitable thermal management of photovoltaic (PV) modules can increase their efficiency. Alongside, the extra amount of energy needed for their thermal management should also be minimized to improve the overall efficiency of the PV system. This leads to exploring passive thermal management techniques. Recently, radiative cooling (RC) has been explored widely as a passive thermal management technique for PV systems. This paper explores radiative cooling and heat sink (HS) as passive methods for thermal regulation of the photovoltaic systems to get lower and uniform temperature distribution along the PV module. A comprehensive two-dimensional model of the proposed system is developed and analyzed in commercial COMSOL Multiphysics software. The governing equations are solved numerically using finite element methods, and simulations are carried out. Four different configurations, namely Case-0: photovoltaic-only system, Case-1: photovoltaic + heat sink, Case-2: photovoltaic + radiative cooling, and Case-3: photovoltaic + heat sink + radiative cooling systems, are considered in this analysis. The performance of four cases has been compared regarding PV temperature reduction, power output, and conversion efficiency. The performance analysis is carried out for the climatic conditions of the Atacama Desert. The results indicated that the photovoltaic + heat sink + radiative cooling system, i.e., Case-3, is the most efficient among all cases. The reduction in the maximum PV operating temperature and improvements in the maximum PV power output and minimum PV conversion efficiency of the photovoltaic + heat sink + radiative cooling system compared to that of the photovoltaic system alone are 6.63%, 8.57%, and 11.11%, respectively. The findings of this study can be used to effectively design the cooling system for the thermal management of photovoltaic modules installed in desert locations. | Kumar, Ramesh; Montero, Francisco J.; Rehman, Tauseef-ur; Lamba, Ravita; Vashishtha, Manish; Upadhyaya, Sushant | Malaviya Natl Inst Technol Jaipur, Dept Chem Engn, JLN Marg, Jaipur 302017, Rajasthan, India; Univ Fuerzas Armadas ESPE, Dept Ciencias Energia & Mecan, POB 171-5-231B, Sangolqui, Ecuador; Pontificia Univ Catolica Chile, Escuela Ingn, Dept Ingn Mecan & Met, Vicuna Mackenna 4860, Santiago 7820436, Chile; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Malaviya Natl Inst Technol Jaipur, Dept Elect Engn, JLN Marg, Jaipur 302017, Rajasthan, India | ; Montero, Francisco/GLQ-5098-2022; Rehman, Tauseef-ur/AAE-3086-2022; Upadhyaya, Sushant/AAS-9591-2020; Lamba, Ravita/E-2899-2019 | 58324853100; 57201877489; 57159403400; 55943560100; 26434549700; 7005821484 | tauseef@knu.ac.kr; | JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY | J THERM ANAL CALORIM | 1388-6150 | 1588-2926 | 148 | 17 | SCIE | CHEMISTRY, ANALYTICAL;CHEMISTRY, PHYSICAL;THERMODYNAMICS | 2023 | 3 | 27.6 | 1.79 | 2025-06-25 | 8 | 11 | Energy efficiency; Heat sink; Photovoltaics; Power output; Thermal management | ECONOMIC-ENVIRONMENTAL EVALUATION; COMPREHENSIVE ANALYSIS; PANELS | Energy efficiency; Heat sink; Photovoltaics; Power output; Thermal management | Conversion efficiency; Cooling systems; Heat sinks; Solar panels; Temperature control; Thermoelectric equipment; Climate condition; Energy; Extreme climates; Management techniques; Photovoltaic modules; Photovoltaic systems; Photovoltaics; Power output; Radiative cooling; Radiative cooling system; Energy efficiency | English | 2023 | 2023-09 | 10.1007/s10973-023-12291-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Strength and stiffness characteristics of cement paste-slime mixtures for embedded piles | Slime is produced by excavation during the installation of embedded piles, and it tends to mix with the cement paste injected into the pile shafts. The objective of this study is to investigate the strength and stiffness characteristics of cement paste -slime mixtures. Mixtures with different slime ratios are prepared and cured for 28 days. Uniaxial compression tests and elastic wave measurements are conducted to obtain the static and dynamic properties, respectively. The uniaxial compressive strengths and static elastic moduli of the mixtures are evaluated according to the curing period, slime ratio, and water-cement ratio. In addition, dynamic properties, e.g., the constrained, shear, and elastic moduli, are estimated from the compressional and shear wave velocities. The experimental results show that the static and dynamic properties increase under an increase in the curing period but decrease under an increase in the slime and water-cement ratios. The cement paste-slime mixtures show several exponential relationships between their static and dynamic properties, depending on the slime ratio. The bearing mechanisms of embedded piles can be better understood by examining the strength and stiffness characteristics of cement paste-slime mixtures. | Byun, Yong-Hoon; Seo, Mi Jeong; Han, WooJin; Kim, Sang Yeob; Lee, Jong-Sub | Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Univ, Sch Civil Environm & Architectural Engn, 145 Anam Ro, Seoul 02841, South Korea; Konkuk Univ, Dept Fire & Disaster Prevent, 268 Chungwon Daero, Chungju 27478, South Korea | Lee, Jong-Sub/G-2752-2012; Han, WooJin/KLZ-1352-2024; Byun, Yong-Hoon/JKI-8441-2023 | 42761048000; 57216538195; 57191676149; 57202787920; 55690048400 | jongsub@korea.ac.kr; | COMPUTERS AND CONCRETE | COMPUT CONCRETE | 1598-8198 | 1598-818X | 31 | 4 | SCIE | COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS;CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, CHARACTERIZATION & TESTING | 2023 | 2.9 | 27.6 | 0.87 | 2025-06-25 | 5 | 5 | cement paste; elastic modulus; elastic wave velocity; embedded pile; slime; uniaxial compressive strength | ULTRASONIC PULSE VELOCITY; WATER/CEMENT RATIO; CONCRETE STRENGTH; SHAFT RESISTANCE; WATER-CONTENT; ABRAMS LAW; PROPAGATION; PREDICTION; MORTARS; BASE | cement paste; elastic modulus; elastic wave velocity; embedded pile; slime; uniaxial compressive strength | Acoustic wave velocity; Compression testing; Compressive strength; Curing; Piles; Shear flow; Shear waves; Soil cement; Stiffness; Wave propagation; Cement paste; Curing periods; Dynamics properties; Elastic wave velocity; Embedded pile; Slime; Static properties; Statics and dynamics; Strength and stiffness characteristics; Uniaxial compressive strength; Elastic moduli | English | 2023 | 2023-04 | 10.12989/cac.2023.31.4.359 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The effects of 4-Phenylbutyric acid on ER stress during mouse tooth development | Introduction: During tooth development, proper protein folding and trafficking are significant processes as newly synthesized proteins proceed to form designated tissues. Endoplasmic reticulum (ER) stress occurs inevitably in tooth development as unfolded and misfolded proteins accumulate in ER. 4-Phenylbutyric acid (4PBA) is a FDA approved drug and known as a chemical chaperone which alleviates the ER stress. Recently, several studies showed that 4PBA performs therapeutic effects in some genetic diseases due to misfolding of proteins, metabolic related-diseases and apoptosis due to ER stress. However, the roles of 4PBA during odontogenesis are not elucidated. This study revealed the effects of 4PBA during molar development in mice. Methods: We employed in vitro organ cultivation and renal transplantation methods which would mimic the permanent tooth development in an infant period of human. The in vitro cultivated tooth germs and renal calcified teeth were examined by histology and immunohistochemical analysis. Results and Discussion: Our results revealed that treatment of 4PBA altered expression patterns of enamel knot related signaling molecules, and consequently affected cellular secretion and patterned formation of dental hard tissues including dentin and enamel during tooth morphogenesis. The alteration of ER stress by 4PBA treatment during organogenesis would suggest that proper ER stress is important for pattern formation during tooth development and morphogenesis, and 4PBA as a chemical chaperone would be one of the candidate molecules for dental and hard tissue regeneration. | Lee, Eui-Seon; Aryal, Yam Prasad; Kim, Tae-Young; Pokharel, Elina; Kim, Ji-Youn; Yamamoto, Hitoshi; An, Chang-Hyeon; An, Seo-Young; Jung, Jae-Kwang; Lee, Youngkyun; Ha, Jung-Hong; Sohn, Wern-Joo; Kim, Jae-Young | Dept Biochem, Daegu, South Korea; Gachon Univ, Dept Dent Hyg, Incheon, South Korea; Tokyo Dent Coll, Dept Histol & Dev Biol, Tokyo, Japan; Dept Oral & Maxillofacial Radiol, Daegu, South Korea; Dept Oral Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, IHBR, Daegu, South Korea; Daegu Haany Univ, Coll Cosmet & Pharmaceut, Dept K Beauty Business, Gyongsan, South Korea | Kim, Ji-Youn/A-5779-2017 | 57202610354; 57202611163; 57208461628; 57220028220; 57157491000; 55725330600; 17134437600; 55258203200; 55970994400; 36062942200; 55549831900; 44161404800; 56812734700 | jykim91@knu.ac.kr; | FRONTIERS IN PHYSIOLOGY | FRONT PHYSIOL | 1664-042X | 13 | SCIE | PHYSIOLOGY | 2023 | 3.2 | 27.6 | 0.16 | 2025-06-25 | 1 | 1 | chemical chaperones; dentinogenesis; morphogenesis; secretion; signaling | HISTONE DEACETYLASE INHIBITORS; ENDOPLASMIC-RETICULUM STRESS; APOPTOSIS; PROLIFERATION; CELLS; XBP1 | chemical chaperones; dentinogenesis; morphogenesis; secretion; signaling | 4 phenylbutyric acid; chaperone; animal experiment; animal tissue; Article; cellular secretion; controlled study; dentin; dentinogenesis; embryo; enamel; endoplasmic reticulum stress; female; histology; immunohistochemistry; in vitro study; kidney transplantation; male; mouse; nonhuman; organ culture; organogenesis; permanent tooth; tissue regeneration; tooth development; tooth germ | English | 2023 | 2023-01-04 | 10.3389/fphys.2022.1079355 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Thermal cure kinetics of cold-setting melamine-urea-formaldehyde resins with high melamine content | Even though cure kinetics of melamine-urea-formaldehyde (MUF) resins with low melamine contents (0-20 mass%) and high-temperature curing have been studied, research on the thermal cure kinetics of cold-setting MUF resins with relatively high melamine content (20-40 mass%) is limited. Therefore, this study reports thermal cure kinetics of cold-setting MUF resins synthesized with three melamine contents, using differential scanning calorimetry. A model-fitting method (Kissinger), three model-free kinetic methods (Friedman (FR), Flynn-Wall-Ozawa (FWO), and Kissinger-Akahira-Sunose (KAS)), and a nonlinear isoconversional (or Vyazovkin) method were employed to theoretically estimate the cure kinetics of cold-setting MUF resins with high melamine content. The results of Kissinger analysis provided reliable activation energy (E-a) which was also comparable with those of isoconversional analysis. As the degree of conversion (alpha) increased, the activation energy (E-alpha) of MUF resins decreased, regardless of melamine content. However, the activation energy (E-a), isoconversional activation energy (E-alpha), and the peak temperature (T-p) increased as the melamine content increased. Two methods such as KAS and Vyazovkin methods were reliable in estimating their cure kinetics based on R-2 values and cure kinetic parameters. Analysis of the cure kinetics showed that all melamine contents MUF resins followed an nth-order reaction (OR (n > 1)) model. | Lee, Jaewook; Park, Byung-Dae | Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea | ; Park, Byung-Dae/ABB-1934-2020 | 58243950800; 7402834820 | byungdae@knu.ac.kr; | JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY | J THERM ANAL CALORIM | 1388-6150 | 1588-2926 | 148 | 13 | SCIE | CHEMISTRY, ANALYTICAL;CHEMISTRY, PHYSICAL;THERMODYNAMICS | 2023 | 3 | 27.6 | 1.3 | 2025-06-25 | 6 | 8 | Cure kinetics; Cold-setting; MUF resins; Melamine content; Reaction model | ACTIVATION-ENERGY; ISOCONVERSIONAL METHOD; CURING BEHAVIOR; DEGRADATION; ADHESIVE; THERMOGRAVIMETRY; PARTICLEBOARD; COMPUTATIONS; PERFORMANCE; INTERPHASE | Cold-setting; Cure kinetics; Melamine content; MUF resins; Reaction model | Curing; Formaldehyde; Metabolism; Reaction Kinetics; Urea; Activation analysis; Curing; Differential scanning calorimetry; Formaldehyde; Kinetics; Metabolism; Reaction kinetics; Synthetic resins; Urea; Urea formaldehyde resins; Activation energy E; Cold-setting; Cure kinetics; Isoconversional; Kissinger; Mass temperature; Melamine content; Melamine-urea-formaldehyde resin; Reaction modelling; Thermal cures; Activation energy | English | 2023 | 2023-07 | 10.1007/s10973-023-12167-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Thermal cure kinetics of highly branched polyurea resins at different molar ratios | Highly branched polyurea (HBPU) resins have been developed as wood adhesives even though their cure kinetics was not well understood. Here, we report thermal cure kinetics of HBPU resins at three molar ratios (2.0, 2.5, and 3.0), using differential scanning calorimetry. A main endothermic peak at 200-240 degrees C of HBPU resins was used to calculate their thermal cure kinetics with several model-free kinetics methods such as Friedman (FR), Flynn-Wall-Ozawa (FWO), and Kissinger-Akahira-Sunose (KAS) method. Furthermore, Malek method was also used to predict an optimal reaction model. Thermal curing of HBPU resins changed from chemical-controlled reaction at low molar ratio to diffusion controlled one at high molar ratio, as the molar ratio of HBPU resins increased. FWO method was suitable for calculating the activation energy of 2.0 HBPU resins, while FR method was suitable for 2.5 and 3.0 HBPU resins. Furthermore, Malek method revealed that all of HBPU resins apparently followed autocatalytic reaction model, regardless of molar ratios. In addition, FWO and KAS method was appropriate to predict the reaction model of 2.0 and 3.0 HBPU resins with Malek method. | Park, Seongsu; Yang, Long; Park, Byung-Dae; Du, Guanben | Kyungpook Natl Univ, Dept Wood & Paper Sci, Daegu 41566, South Korea; Southwest Forestry Univ, Int Joint Res Ctr Biomass Mat, Yunnan Prov Key Lab Wood Adhes & Glued Prod, Kunming 650224, Peoples R China | Park, Byung-Dae/ABB-1934-2020 | 57220771754; 55565835600; 7402834820; 12781191100 | byungdae@knu.ac.kr;guanben@swfu.edu.cn; | JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY | J THERM ANAL CALORIM | 1388-6150 | 1588-2926 | 148 | 13 | SCIE | CHEMISTRY, ANALYTICAL;CHEMISTRY, PHYSICAL;THERMODYNAMICS | 2023 | 3 | 27.6 | 0.49 | 2025-06-25 | 3 | 3 | Cure kinetics; Polyurea resin; Endothermic; Kinetic model; Wood adhesives | EPOXY-RESIN; MODEL-FREE; ADHESIVE | Cure kinetics; Endothermic; Kinetic model; Polyurea resin; Wood adhesives | Activation Energy; Adhesives; Calorimetry; Curing; Diffusion; Kinetics; Polyureas; Ratios; Activation energy; Adhesives; Curing; Differential scanning calorimetry; Kinetics; Molar ratio; Cure kinetics; Endothermic; Flynn-Wall-Ozawa; Kinetic models; Kissinger; Molar ratio; Polyurea resin; Polyureas; Thermal cures; Wood adhesives; Resins | English | 2023 | 2023-07 | 10.1007/s10973-023-12160-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Design Methodology of U-Shaped Infilled Composite Beams with Angled Shear Connectors Using Finite Element Analysis | A composite beam is a structural member that behaves as a single unit by using shear connectors between a concrete slab and an I-shaped steel girder. The composite ratio is crucial and is determined by the shear connectors' ability to withstand the horizontal shear forces between the concrete and steel girder. In this study, a U-shaped composite beam was designed, which differs from conventional composite beams as it allows the use of a steel girder as a formwork. Moreover, angle-type shear connectors, instead of stud-type connectors, were employed. Based on this design, large-scale U-shaped composite beams with angle-type shear connectors were fabricated, and load tests were conducted to analyze the behavior after composite action and the influence of shear connector spacing. Additionally, the strength of the angle-type shear connectors used in this paper was evaluated through finite element analysis. Finally, a strength evaluation method for composite beams of this configuration is proposed. | Lee, Jun-Seop; Woo, Jong-Hun; Shin, Kyung-Jae; Lee, Hee-Du | Kyungpook Natl Univ, Reg Ctr Land Infrastruct & Transport Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea | 57221623386; 57210344487; 14039501000; 53865180300 | kore6987@knu.ac.kr;wdusdka@knu.ac.kr;shin@knu.ac.kr;lhdza@knu.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 13 | 9 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2023 | 3.1 | 27.7 | 0 | 2025-06-25 | 0 | 0 | infilled composite beam; horizontal shear; finite element analysis (FEM) | CONCRETE; STEEL | finite element analysis (FEM); horizontal shear; infilled composite beam | English | 2023 | 2023-09 | 10.3390/buildings13092221 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Discrimination of the geographical origin of dry red pepper using inorganic elements: A multielement fingerprinting analysis | This study was based on inductively coupled plasma optical emission spectroscopy and mass spectrometry. The purpose of this study was to develop an accurate method for clearly discriminating the origin of dry red pepper. Sixty-four domestic and 51 imported samples were acid treated in a microwave system. The geographical origin of each sample was identified using the contents of 60 elements. The OPLS-DA results showed that the R-2 and Q(2) values were 0.873 and 0.765, respectively, indicating a high ratio and prediction ratio of this model. A total of 26 elements with a VIP (Variable Importance in Projection) value of greater than 1 were selected, and each element had a decisive influence on the domestic and imported groups. An ROC (Receiver Operating Characteristic) analysis confirmed the accuracy of the identification of domestic and imported products using the selected 26 elements. The accuracy based on the ROC was 98.7%. A heatmap was used to select elements that were influential in identifying domestic and imported dry red pepper samples. All of the most influential elements were rare earth elements (REEs). The REE content of dry red pepper was significantly higher in imported than in domestic samples. CDA (Canonical Discriminant Analysis) showed that the accuracy of classification by group was 100% for each group. | Hur, Suel Hye; Kim, Hyoyoung; Kim, Yong-Kyoung; An, Jae Min; Lee, Ji Hye; Kim, Seyeon; Choi, Young-Hwa; Kim, Ho Jin | Natl Agr Prod Qual Management Serv, Gimcheon 39660, South Korea; Kyungpook Natl Univ, Div Ecol & Environm Syst, Sangju 37224, South Korea | Kim, Hyo Yeol/HLP-5150-2023; Kim, Young Hoon/F-5424-2012; Kim, Seung/N-5248-2019 | 56645888400; 57224535109; 57918934100; 57855509300; 57217259202; 58002197200; 58001753500; 56372903900 | rearnature@naver.com;hyo02@korea.kr;ykkim79@korea.kr;ahjm@korea.kr;toshil1999@korea.kr;syesther1114@naver.com;ychoi@knu.ac.kr;rex7878@korea.kr; | JOURNAL OF FOOD COMPOSITION AND ANALYSIS | J FOOD COMPOS ANAL | 0889-1575 | 1096-0481 | 116 | SCIE | CHEMISTRY, APPLIED;FOOD SCIENCE & TECHNOLOGY | 2023 | 4 | 27.7 | 1.85 | 2025-06-25 | 13 | 13 | Geographical origin; ICP3OES/MS; Rare earth element; Dry red pepper; Statistical analysis | RARE-EARTH-ELEMENTS; ICP-OES; OPLS-DA; ANTIOXIDANT; CAPSAICIN; SOILS; TEA | Dry red pepper; Geographical origin; ICP3OES/MS; Rare earth element; Statistical analysis | English | 2023 | 2023-03 | 10.1016/j.jfca.2022.105076 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Experimental and Theoretical Analysis of Flexural Properties of Mortar Beam Reinforced with Coated Carbon-Fiber Textile | The flexural behavior of mortar beams reinforced with coated carbon-fiber textile was experimentally analyzed in this study. Accordingly, pull-out and bending tests were performed on textile-reinforced mortar (TRM) beam specimens. The experimental results demonstrated the superior bond performance of the coated carbon-fiber textile. The TRM beam exhibited sufficient ductility even after the occurrence of flexural cracks. In addition, a theoretical analysis method for predicting the flexural behavior of a TRM beam was established based on the experimentally determined bond behaviors of the textile reinforcement in cementitious materials. The analysis demonstrated that the bending behavior of the TRM beam was reasonably predicted. The results of this study can serve as basic data for the structural application of textile-reinforced cementitious composites. | Hong, Geuntae; Park, Jangsoon; Lee, Seong-Cheol; Cha, Soo Won; Ryu, Jaewoo; Choi, Seongcheol | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Water Resources Corp, Songsan Green City Project Off, 6-50 Dongi Gil, Hwaseong Si 18245, Gyeonggi Do, South Korea; Univ Ulsan, Dept Civil & Environm Engn, 93 Daehak Ro, Ulsan 44610, South Korea; Chung Ang Univ, Dept Civil & Environm Engn, 84 Heukseok Ro, Seoul 06974, South Korea | Choi, Seongcheol/AAV-1413-2020; Hong, Geuntae/AAM-8586-2020 | 57193714827; 57204641664; 35784449900; 7201865554; 58626369700; 35221260900 | gthong@knu.ac.kr;jsoon@kwater.or.kr;seonglee@knu.ac.kr;chasw@ulsan.ac.kr;yjw1648@naver.com;schoi@cau.ac.kr; | BUILDINGS | BUILDINGS-BASEL | 2075-5309 | 13 | 9 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2023 | 3.1 | 27.7 | 0 | 2025-06-25 | 0 | 1 | carbon-fiber textile; flexural behavior; pull-out; reinforcement; textile-reinforced mortar (TRM) | POLYVINYL-ALCOHOL PVA; PULL-OUT; RC BEAMS; CONCRETE; BEHAVIOR; BOND; EFFICIENCY; MASONRY; GLASS; SLIP | carbon-fiber textile; flexural behavior; pull-out; reinforcement; textile-reinforced mortar (TRM) | English | 2023 | 2023-09 | 10.3390/buildings13092157 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Influence of Sectional Depth on Structural Behavior of Bridge Pier Caps | A parametric study using finite-element (FE) analysis was conducted over a range of sectional depths to investigate the effect of the pier caps' sectional depth on structural safety and serviceability for pier caps with a simple determinate strut-and-tie models (STMs) design. The influence of sectional depth on the shear strength of the pier caps was also analyzed using pier caps with over-reinforced flexural rebar inducing shear failures. Analytical studies using determinate STMs showed that the amount of vertical shear reinforcement did not change regardless of the sectional depth of the pier cap. In contrast, the FE analysis suggested that excessive sectional depth could lead to overly conservative shear designs. In addition, the FE analysis showed that crack serviceability could be efficiently satisfied by constraining the pier caps' minimal sectional depth. Based on the FE analysis, design guidelines for simple determinate STMs were proposed to determine efficient sectional depths in pier cap design. | Park, Jae-Hyun; Lee, Seong-Cheol; Cho, Jae-Yeol | Korea Inst CivilEngineering & Bldg Technol, Dept Struct Engn Res, 283, Goyang Si 10223, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Dept Civil Engn, 80, Daehak ro, Daegu 41566, South Korea; Seoul Natl Univ, Dept Civil & Environm Engn, 1, Gwanak ro, Seoul 08826, South Korea | Cho, Jae-Yeol/D-4818-2011 | pjh0411@kict.re.kr;seonglee@knu.ac.kr;jycho@snu.ac.kr; | JOURNAL OF BRIDGE ENGINEERING | J BRIDGE ENG | 1084-0702 | 1943-5592 | 28 | 7 | SCIE | ENGINEERING, CIVIL | 2023 | 3.1 | 27.7 | 0 | Bridge pier cap; Sectional depth; Nonlinear FE analysis; Shear reinforcement ratio; Shear strength; Strut-and-tie model | STRESS-FIELD MODEL; REINFORCED-CONCRETE; STEEL REINFORCEMENT | English | 2023 | 2023-07-01 | 10.1061/jbenf2.beeng-6090 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Lead Oxide Nanoparticles as X-ray Contrast Agents for In Vitro and In Vivo Imaging | Lead oxide (PbO) nanoparticles are promising candidates for X-ray contrast agents because Pb (atomic number = 82) possesses the second largest X-ray attenuation coefficient of all nonradioactive elements in the periodic table. However, few studies have been conducted on PbO nanoparticles. This study is the first to synthesize hydrophilic and biocompatible polymer-grafted ultrasmall PbO nanoparticles with a polyol method. In addition, their potential as X-ray contrast agents was investigated in vitro and in vivo. Three kinds of polymers, namely poly(methyl vinyl ether-alt-maleic acid) (PMVEMA), poly(acrylic acid-co- maleic acid) (PAAMA), and poly(acrylic acid) (PAA), served as surface-grafting polymers of ultrasmall PbO nanoparticles. The synthesized polymer-grafted ultrasmall PbO nanoparticles were colloidally stable (i.e., no precipitation), nearly monodispersed in particle diameters with average particle diameters of 2.0, 1.9 and 2.0 nm for the PAA-, PAAMA-, and PMVEMA-grafted ultrasmall PbO nanoparticles, respectively, exhibiting very-low cellular cytotoxicity. Based on the identical atomic concentration and the identical number density, the X-ray attenuation efficiencies of the polymer-grafted ultrasmall PbO nanoparticles were similar to 3 and similar to 140 times greater, respectively, compared with those of a commercially available contrast agent Ultravist. Their potential as X-ray contrast agents was proved in vivo by observing contrast enhancements in organs after intravenous tail and intraperitoneal injections in mice. In addition, the nanoparticles demonstrated tumor-imaging ability through contrast enhancements at the tumor after intratumoral injection in tumor-model mice. | Al Saidi, Abdullah Khamis Ali; Baek, Ahrum; Liu, Shuwen; Mengesha, Tirusew Tegafaw; Ahmad, Mohammad Yaseen; Zhao, Dejun; Liu, Ying; Yang, Ji-ung; Park, Ji Ae; Hwang, Dong Wook; Chae, Kwon Seok; Nam, Sung-Wook; Chang, Yongmin; Lee, Gang Ho | Kyungpook Natl Univ, Coll Nat Sci, Dept Chem, Taegu 41566, South Korea; Kyungpook Natl Univ, Inst Biomed Engn, Sch Med, Taegu 41944, South Korea; Korea Inst Radiol & Med Sci, Div RI Convergence Res, Seoul 01817, South Korea; Kyungpook Natl Univ, Dept Biomed Sci, Taegu 41944, South Korea; Kyungpook Natl Univ, Teachers Coll, Dept Biol Educ, Taegu 41566, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Taegu 41944, South Korea | ; Ahmad, Mohammad/AAH-2164-2020; Liu, Shuwen/ABD-5719-2021; Nam, Sung-Wook/V-5519-2019 | 57217492867; 57194601711; 57208926248; 57215027413; 57203054570; 57222567792; 57221731093; 57212217968; 16319690600; 57749644800; 15743626400; 16167127700; 7501840633; 7404851841 | ychang@knu.ac.kr;ghlee@mail.knu.ac.kr; | ACS APPLIED NANO MATERIALS | ACS APPL NANO MATER | 2574-0970 | 6 | 21 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 5.3 | 27.7 | 0.41 | 2025-06-25 | 4 | 4 | ultrasmall PbO nanoparticle; polymer-grafting; X-ray attenuation; X-ray contrast agent; in vivoimaging; tumor imaging | COMPUTED-TOMOGRAPHY; GOLD NANOPARTICLES; FACILE SYNTHESIS; BASES HSAB; SOFT ACIDS; POLYMER; SURFACE; HARD; CT; MR | in vivo imaging; polymer-grafting; tumor imaging; ultrasmall PbO nanoparticle; X-ray attenuation; X-ray contrast agent | Atoms; Biocompatibility; Carboxylic acids; Grafting (chemical); Iron oxides; Lead oxide; Mammals; Particle size; Precipitation (chemical); Synthesis (chemical); Tumors; In-Vivo imaging; Maleic acids; PbO nanoparticles; Poly(acrylic acid); Polymer grafting; Tumor imaging; Ultra-small; Ultrasmall PbO nanoparticle; X-ray attenuation; X-ray contrast agents; Nanoparticles | English | 2023 | 2023-10-20 | 10.1021/acsanm.3c03928 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Nitrogen-Doped Graphitic Carbon Dots Embedded in Carbon Nitride Scaffolds for Water Decontamination | Functionalized carbon dots (CDs) exhibit intriguing photo-exciton dynamics. CDs can donate or accept electrons depending on their functional groups and electrostatic characteristics. We exploited the electron-accepting capability of nitrogen-doped graphitic carbon dots (N-g-CDs) to improve the charge-carrier separation of the polymeric carbon nitride (PCN) photocatalyst. l-Aspartic acid pyrolyzed at 320 °C yielded ∼25 nm size N-g-CDs that were embedded with PCN. The in-plane infiltration of nanosized N-g-CDs increased the surface area of PCN from 11.5 to 104.9 m2 g-1. The N-g-CDs/PCN hybrid catalyst tested for photocatalytic chromium reduction evidenced about a 3-fold higher rate than PCN. Also, the antibiotic tetracycline and rhodamine B dye rapidly degraded with faster degradation kinetics. The carrier dynamic analysis and computational investigations suggest that the electron acceptor feature of N-g-CDs governs the effective separation of photo-excitons and the high surface area of N-g-CDs/PCN contributes to photoactivity enhancement. This study offers insights into designing high-performance metal-free photocatalysts for water treatment applications. © 2023 American Chemical Society. | Bhoyar, Toshali; Saraswat, Nishprah; Jyothirmai, M.V.; Gupta, Akanksha; Malla, Sunita Kumari; Park, Jiyeon; Vidyasagar, Devthade; Umare, Suresh S. | Materials and Catalysis Laboratory, Department of Chemistry, Visvesvaraya National Institute of Technology (VNIT), Nagpur, 440010, India; Materials and Catalysis Laboratory, Department of Chemistry, Visvesvaraya National Institute of Technology (VNIT), Nagpur, 440010, India; Department of Chemical Engineering, Indian Institute of Technology, Kanpur, 208016, India; Department of Chemistry, Bar-Ilan University, Ramat Gan, 5290002, Israel; Materials and Catalysis Laboratory, Department of Chemistry, Visvesvaraya National Institute of Technology (VNIT), Nagpur, 440010, India; School of Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; Materials and Catalysis Laboratory, Department of Chemistry, Visvesvaraya National Institute of Technology (VNIT), Nagpur, 440010, India; Materials and Catalysis Laboratory, Department of Chemistry, Visvesvaraya National Institute of Technology (VNIT), Nagpur, 440010, India | 57211356285; 58121737600; 57203092766; 57704090900; 58122485200; 57218367393; 57201674442; 6506241250 | vidyasagar.devtade@gmail.com;ssumare1965@gmail.com; | ACS Applied Nano Materials | ACS APPL NANO MATER | N/A | 2574-0970 | 6 | 5 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2023 | 5.3 | 27.7 | 1.14 | 2025-06-25 | 11 | chromium reduction; nitrogen-doped graphitic carbon dots; photooxidation; polymeric carbon nitride; tetracycline | Amino acids; Carbon nitride; Chromium; Degradation; Doping (additives); Excitons; Photooxidation; Scaffolds; Water treatment; Carbon dots; Chromium reduction; Exciton dynamics; Functionalized; Graphitic carbons; Nitrogen-doped; Nitrogen-doped graphitic carbon dot; Polymeric carbon nitride; Tetracycline; Water decontamination; Image enhancement | English | Final | 2023 | 10.1021/acsanm.2c05239 | 바로가기 | 바로가기 | 바로가기 |
