○ ○ Article ⓘ Anti-Inflammatory and Prebiotic Potential of Ethanol Extracts and Mucilage Polysaccharides from Korean Yams (Dioscorea polystachya and Dioscorea bulbifera) ⓘ Korean yams are abundant in bioactive compounds with significant health-promoting properties. This study evaluated the anti-inflammatory potential of ethanol and water extracts from Dioscorea polystachya and Dioscorea bulbifera in RAW 264.7 macrophage cells. Among the extracts, the 95% ethanol extract exhibited the most potent inhibition of reactive oxygen species (ROS) and nitric oxide (NO) production, warranting further exploration of its mechanisms of action. Further analysis revealed that the ethanol extract modulated key inflammatory signaling pathways, including MAPK and NF-kappa B, contributing to its anti-inflammatory activity. Additionally, mucilage polysaccharides, a key bioactive component of Korean yams, were extracted and characterized for their structural and functional properties. These polysaccharides demonstrated immune-enhancing effects by reducing ROS and NO production while increasing phagocytic activity in the RAW 264.7 cells. Their prebiotic potential was also assessed through microbial growth assays, which showed an enhanced proliferation of beneficial bacteria such as Lactobacillus and Bifidobacterium. Furthermore, the adhesion assays using Caco-2 intestinal epithelial cells revealed that these polysaccharides promoted probiotic adhesion while inhibiting the adhesion of pathogenic bacteria. These findings highlight the bioactive potential of ethanol extracts and mucilage polysaccharides from Korean yams, emphasizing their promising applications as anti-inflammatory, immune-modulating, and prebiotic agents for functional food and nutraceutical development. ⓘ Park, So-Yoon; Truong, Van-Long; Jeon, Su-Gyeong; Choe, So-Young; Rarison, Razanamanana H.

○ ○ Article ⓘ Effects of Structural Changes in Cross-Linked Mung Bean Starch on Freeze-Thaw Properties and In Vitro Digestibility ⓘ This study aims to evaluate the effects of structural changes in cross-linked mung bean starch (CLMB) on freeze-thaw stability and in vitro digestibility and explore its potential to prevent starch retrogradation and its applicability as a resistant starch (RS)- enhanced food ingredient. Mung beans of different varieties (Eohul, Geumsung, and Sohyeon) were cross-linked using an STMP:STPP ratio of 9:1. The structure and thermal properties of CLMB and its digestibility, as well as the textural properties of 10% CLMB gels and their freeze-thaw stability, were evaluated. As a result of the study, CLMB maintained an A-type crystalline structure, but structural changes due to the introduction of phosphate groups were observed during FT-IR analysis. Compared to natural mung bean starch (MBS), the swelling power and solubility decreased, and the gelatinization temperature range increased. Additionally, the cross-linking treatment increased the resistant starch (RS) content. In the case of the gel with 10% CLMB added, the freezing-thawing experiment results show a significant reduction in syneresis and it was confirmed that high stability was maintained even through repeated processes. Our results suggest that CLMB is a functional ingredient with potential applications in the development of food products offering extended shelf lives and tailored nutritional benefits. ⓘ Agvaandorj, Altantungalag; Li, Yuanzao; No, Junhee ⓘ Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu 41566, South Korea; Kyungpook Natl Univ, Ctr Beautiful Aging, Daegu 41566, South Korea ⓘ ⓘ 59655701800; 59654908000; 57188876908 ⓘ tungalag0302@knu.ac.kr; lyz2024@knu.ac.kr; junheeno@knu.ac.kr; ⓘ FOODS ⓘ FOODS ⓘ 2304-8158 14 4 SCIE FOOD SCIENCE & TECHNOLOGY ⓘ 2024 5.1 22.9 0 2025-05-07 ⓘ 0 0 mung bean starch; cross-linked starch; resistant starch; RS4; in vitro digestibility; freeze-thaw stability ⓘ PHYSICOCHEMICAL PROPERTIES; RESISTANT STARCH; RHEOLOGICAL PROPERTIES; FUNCTIONAL-PROPERTIES ⓘ cross-linked starch; freeze–thaw stability; in vitro digestibility; mung bean starch; resistant starch; RS4 ⓘ ⓘ English 2025 2025-02 10.3390/foods14040689 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Effects on Physicochemical, Nutritional, and Quality Attributes of Fortified Vegan Muffins Incorporated with Hempseed as an Alternative Protein Source ⓘ This study investigated the potential of hempseed protein isolate (HPI) as a protein fortifier and wheat flour substitute in vegan muffins. HPI was incorporated at 0% (CON), 10% (HP10), 20% (HP20), and 30% (HP30) substitution levels, and muffins were evaluated for physicochemical, functional, and sensory properties. Protein content significantly increased from 9.61% (CON) to 19.40% (HP30), while baking loss decreased from 21.33% to 19.77%, reflecting HPI's superior water-holding capacity. Texture analysis showed hardness decreased from 179.72 g/cm2 (CON) to 137.73 g/cm2 (HP30), resulting in softer muffins with higher chewiness. This correlated with a more aerated crumb structure and smoother surface at higher HPI levels, indicating improved structural integrity. Rheological analysis revealed increased batter viscosity and shear-thinning behavior with HPI fortification. FTIR analysis exhibited redshifts in the Amide I and Amide II bands, suggesting enhanced protein-protein interactions and hydrogen bonding in fortified HPI muffins. Antioxidant activity increased significantly, with ABTS radical scavenging values rising from 32.66% (CON) to 46.28% (HP30), attributed to the bioactive peptides and phenolic compounds (144.67 mg GAE/g) in HPI. However, in vitro protein digestibility (IVPD) decreased from 66.08% to 42.63% due to protein-starch-lipid interactions inhibiting hydrolysis. Sensory evaluation showed no significant differences in aroma, taste, mouthfeel, or overall acceptability, with scores between 4.83 and 5.33 among all samples. These results demonstrate that HPI incorporation of up to 30% significantly enhances the nutritional profile, antioxidant activity, and textural properties of vegan muffins while maintaining overall sensory quality, supporting HPI's potential as a sustainable protein fortifier in plant-based bakery products. ⓘ Du, Huimin; Baek, Inha; Jang, Yunju; Said, Nurul Saadah; Lee, Won Young ⓘ Kyungpook Natl Univ, Sch Food Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Tailored Food Technol, Daegu 41566, South Korea ⓘ Lee, Wonyoung/AAL-2780-2021; Said, Nurul Saadah/LFV-3208-2024; Niu, Bailin/AAA-3311-2019 ⓘ 59004196400; 59201697100; 59654888400; 57211398275; 57195940408 ⓘ duhuimin1998@naver.com; ggotari@naver.com; yunju@knu.ac.kr; nurulsaadah.said@gmail.com; wonyoung@knu.ac.kr; ⓘ FOODS ⓘ FOODS ⓘ 2304-8158 14 4 SCIE FOOD SCIENCE & TECHNOLOGY ⓘ 2024 5.1 22.9 0 2025-05-07 ⓘ 0 0 hempseed protein; protein fortification; vegan muffin; baking properties; antioxidant activity; sensory evaluation ⓘ HEALTH-BENEFITS; ISOLATE; PRODUCTS; CAKE; RICH ⓘ antioxidant activity; baking properties; hempseed protein; protein fortification; sensory evaluation; vegan muffin ⓘ ⓘ English 2025 2025-02 10.3390/foods14040601 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Nutritional Components and Digestibility Profiles of Some Potential Plant-Based Protein Sources ⓘ Background: The dominance of soybeans as the primary plant protein source has hindered the exploration of potential sources, limiting dietary diversity and innovation. Objective/Methods: This study evaluated six plant protein sources-mung bean (MB), bambara bean (BN), jack bean (JB), sesame seed (SS), moringa seed (MS), and rice bran (RB)-compared to soybean (SB) for their chemical composition and biological qualities using standard methods. Results: Protein composition (14.98-30.29 g/100 g), fiber (2.90-8.18 g/100 g), and fat (5.19-33.30 g/100 g) varied across plants. Bulk density (0.49-0.74 g/mL), swelling capacity (0.25-0.55%), and yellowness (13.07-38.76) were comparable to SB. Electropherograms showed major protein bands at 20, 48, 75, and 100 kDa across plant proteins under non-reducing conditions. Phytate levels were highest in RB, while MS showed lower tannic acid composition (6.64 mg/100 g) compared to SB. Protein solubility (24.64-45.65%) increased with pH, while in vitro protein digestibility (74.86-87.64%) varied and was slightly below SB (91.07%); however, a similar pattern of protein digestion was observed under no reducing condition. MS and BN contained 31.17% and 42.47% of total essential amino acids with PDCAAS values of 41.42% and 58.46%, respectively. Conclusions: Overall, MS and BN exhibited superior potential as sustainable protein sources, showing properties comparable to soybean. ⓘ Anyiam, Paul Ndubuisi; Phongthai, Suphat; Sai-Ut, Samart; Kingwascharapong, Passakorn; Jung, Young Hoon; Zhang, Wanli; Rawdkuen, Saroat ⓘ Mae Fah Luang Univ, Sch Agroind, Innovat Food Sci & Technol Program, Chiang Rai 57100, Thailand; Michael Okpara Univ Agr, Coll Nat Sci, Dept Biochem, PMB 7262, Umuahia, Abia, Nigeria; Chiang Mai Univ, Fac Agroind, Div Food Sci & Technol, Chiang Mai 50100, Thailand; Burapha Univ, Fac Sci, Chon Buri 20131, Thailand; Kasetsart Univ, Fac Fisheries, Dept Fishery Prod, Bangkok 10900, Thailand; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Hainan Univ, Coll Food Sci & Technol, Haikou 570228, Peoples R China; Mae Fah Luang Univ, Sch Agroind, Unit Innovat Food Packaging & Biomat, Chiang Rai 57100, Thailand ⓘ Phongthai, Suphat/AAC-5138-2020; Jung, Young/F-1703-2013; ANYIAM, PAUL NDUBUISI/GWM-5198-2022; Sai-Ut, Samart/NIS-9008-2025 ⓘ 58126720700; 56179620300; 24438322400; 56708865400; 55550063700; 57201591598; 7801639883 ⓘ 6671401002@lamduan.mfu.ac.th; su.phongthai@gmail.com; samarts@go.buu.ac.th; passakorn.ki@ku.th; younghoonjung@knu.ac.kr; zwl@hainanu.edu.cn; saroat@mfu.ac.th; ⓘ FOODS ⓘ FOODS ⓘ 2304-8158 14 10 SCIE FOOD SCIENCE & TECHNOLOGY ⓘ 2024 5.1 22.9 0 2025-06-11 ⓘ 0 1 amino acid; biological qualities; compositions; digestibility; plant-based protein ⓘ MORINGA-OLEIFERA ⓘ amino acid; biological qualities; compositions; digestibility; plant-based protein ⓘ ⓘ English 2025 2025-05-16 10.3390/foods14101769 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Profiling the Nutritional, Phytochemical, and Functional Properties of Mung Bean Varieties ⓘ The Ethiopian Agricultural Research Institute (EARI) adopted four mung bean varieties for cultivation, following extensive research on their adaptability, productivity, and drought tolerance. However, the physicochemical, techno-functional, and antioxidant properties of these cultivars, which can vary significantly due to genetic and agro-ecological differences, have not been sufficiently explored in previous research. Hence, this study aimed to elucidate these properties to facilitate their seamless integration into food formulation and product development. The study results revealed that the protein content of these varieties ranged from 22.63 to 25.84 g/100 g, while carbohydrate content ranged from 54.9 to 58.82 g/100 g. Moreover, all examined varieties exhibited elevated levels of essential amino acids, particularly lysine, phenylalanine, and leucine. The foaming capacity and emulsion activity varied between 40.27-49.2% and 52.75-54.13%, respectively. The loss modulus of all varieties surpassed the storage modulus. Total polyphenol and flavonoid contents ranged from 2.36 to 3.05 mg GAE/g and 1.42 to 2.22 mg QE/g, respectively. The antioxidant activities were assessed using different assays and revealed that all samples were concentration-dependent, with all cultivars exhibiting high antioxidant activity at higher concentrations. The comparative analysis of the examined varieties revealed that none excelled in all of the tested parameters. However, these diverse qualities make Ethiopian mung bean varieties suitable for various food formulations tailored to specific desired characteristics. ⓘ Idris, Fekiya Mohammed; Urga, Kelbessa; Admassu, Habtamu; Fentie, Eskindir Getachew; Kwon, Sook-Min; Shin, Jae-Ho ⓘ Addis Ababa Univ, Coll Nat Sci, Ctr Food Sci & Nutr, Addis Ababa 16417, Ethiopia; Addis Ababa Sci & Technol Univ, Coll Engn, Dept Chem Engn, Food Proc Engn Program, Addis Ababa 16417, Ethiopia; Addis Ababa Sci & Technol Univ, Biotechnol & Bioproc Ctr Excellence, Addis Ababa, Ethiopia; Minist Hlth, Ethiopian Publ Hlth Inst, Addis Ababa 1242, Ethiopia; Kyungpook Natl Univ, NGS Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea ⓘ Fentie, Eskindir/LIG-6089-2024 ⓘ 58543803400; 6602649168; 57195282708; 57245844200; 59469456700; 57224125922 ⓘ mfekiya@yahoo.com; kelbessau@yahoo.com; hadtess2009@gmail.com; eskench@gmail.com; ksv6178@gmail.com; jhshin@knu.ac.kr; ⓘ FOODS ⓘ FOODS ⓘ 2304-8158 14 4 SCIE FOOD SCIENCE & TECHNOLOGY ⓘ 2024 5.1 22.9 0 2025-05-07 ⓘ 0 0 mung bean; lysine; polyphenol; rheology; antioxidant activity; cultivars ⓘ PHYSICOCHEMICAL PROPERTIES; ANTIOXIDANT; PROTEIN; BIOAVAILABILITY; POLYPHENOLS; SOAKING; FLOURS; L. ⓘ antioxidant activity; cultivars; lysine; mung bean; polyphenol; rheology ⓘ ⓘ English 2025 2025-02 10.3390/foods14040571 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Techno-Functional, Rheological, and Physico-Chemical Properties of Gelatin Capsule By-Product for Future Functional Food Ingredients ⓘ The utilization of gelatin capsule waste (GCW) poses a challenge for the industry. This study investigates its potential as a functional food ingredient by evaluating the physico-chemical, rheological, and techno-functional properties of gelatin capsule waste powder (GCWP). To achieve this, the gelatin capsule waste (GCW) was mixed with maltodextrin at varying ratios (1:1, 1:2, 1:3, 1:4, and 1:5) and subjected to spray drying. The findings highlight maltodextrin's crucial role in stabilizing the drying process, reducing stickiness, and enhancing handling and storage properties. All the obtained GCWP samples appeared light white and had a slightly sticky texture. The 1:5 (w/w) GCW-to-maltodextrin ratio produced the highest powder recovery with minimal stickiness, indicating enhanced drying efficiency. Increasing maltodextrin reduced gel strength, texture, and foaming properties while raising the glass transition temperature. The FTIR analysis indicated a decline in protein-protein interactions and increased polysaccharide interactions at higher maltodextrin levels. The rheological analysis demonstrated lower elastic and loss moduli with increased maltodextrin, affecting GCWP's structural behavior. For overall properties, the GCW mixed with maltodextrin at a 1:1 ratio (GCW-1M) is recommended for future applications, particularly for its gelling characteristics. The GCW-1M, being rich in amino acids, demonstrates its potential as a functional food ingredient. However, certain properties, such as gel strength and powder stability (hygroscopicity and stickiness), require further optimization to enhance its industrial applicability as a functional food ingredient. ⓘ Sanprasert, Sasina; Kumnerdsiri, Pudthaya; Seubsai, Anusorn; Lueangjaroenkit, Piyangkun; Pongsetkul, Jaksuma; Indriani, Sylvia; Petcharat, Tanyamon; Sai-ut, Samart; Hunsakul, Kanrawee; Issara, Utthapon; Pawde, Subhash V.; Rawdkuen, Saroat; Karbowiak, Thomas; Jung, Young Hoon; Kingwascharapong, Passakorn ⓘ Kasetsart Univ, Fac Fisheries, Dept Fishery Prod, Bangkok 10900, Thailand; Kasetsart Univ, Fac Engn, Dept Chem Engn, Bangkok 10900, Thailand; Kasetsart Univ, Fac Sci, Dept Microbiol, Bangkok 10900, Thailand; Suranaree Univ Technol, Inst Agr Technol, Sch Anim Technol & Innovat, Nakhon Ratchasima 30000, Thailand; Walailak Univ, Sch Management, Profess Culinary Arts Program, Nakhon Si Thammarat 80161, Thailand; Burapha Univ, Fac Sci, Dept Food Sci, Chon Buri 20131, Thailand; Rajamangala Univ Technol Tawan Ok, Fac Sci & Technol, Div Agroind Prod Dev, Chon Buri 22210, Thailand; Rajamangala Univ Technol Thanyaburi, Fac Sci & Technol, Div Food Sci & Technol Management, Pathum Thani 12110, Thailand; Mae Fah Luang Univ, Sch Agroind, Unit Innovat Food Packaging & Biomat, Chiang Rai 57100, Thailand; Univ Bourgogne Europe, Inst Agro, INRAE, UMR PAM, F-21000 Dijon, France; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Food Sci & Biotechnol, Daegu 41566, South Korea ⓘ Sai-Ut, Samart/NIS-9008-2025; Jung, Young/F-1703-2013; Indriani, Sylvia/AAP-9495-2021; Seubsai, Anusorn/AAE-4541-2020; Jung, Young Hoon/F-1703-2013; KARBOWIAK, Thomas/Q-2151-2018; Pawde, Subhash/ISU-4317-2023 ⓘ 58565320300; 59245540600; 24377221500; 57207203551; 56469829200; 57200308489; 57194511054; 24438322400; 57221477838; 56037825300; 57219053304; 7801639883; 9333012100; 55550063700; 56708865400 ⓘ sasina.sanp@ku.th; pudthaya.ku@ku.th; fengasn@ku.ac.th; piyangkun.lu@ku.th; jaksuma@sut.ac.th; indrianisylvia@gmail.com; tanyamon.pet@gmail.com; samarts@go.buu.ac.th; kanrawee.h@hotmail.com; utthapon_i@rmutt.ac.th; pawdesubhash333@gmail.com; saroat@mfu.ac.th; thomas.karbowiak@institut-agro.fr; younghoonjung@knu.ac.kr; passakorn.ki@ku.th; ⓘ FOODS ⓘ FOODS ⓘ 2304-8158 14 7 SCIE FOOD SCIENCE & TECHNOLOGY ⓘ 2024 5.1 22.9 0 2025-05-07 ⓘ 0 0 gelatin; capsule waste; maltodextrin; techno-functional; future food ingredients ⓘ PROTEIN ISOLATE-MALTODEXTRIN; BASS LATES-CALCARIFER; ANTIOXIDANT PROPERTIES; POWDER; MICROENCAPSULATION; EXTRACTION; CARRIER; JUICE; WHEY; SKIN ⓘ capsule waste; future food ingredients; gelatin; maltodextrin; techno-functional ⓘ ⓘ English 2025 2025-04-07 10.3390/foods14071279 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Microalgae-mediated green synthesis of silver nanoparticles: a sustainable approach using extracellular polymeric substances from Graesiella emersonii KNUA204 ⓘ Traditional nanoparticle synthesis relies on chemical and physical methods that often involve hazardous reagents, high energy consumption, and environmental toxicity. As a sustainable alternative, biological synthesis utilizes biomolecules in an eco-friendly manner to form nanoparticles. This study explores the green synthesis of silver nanoparticles (AgNPs) using extracellular polymeric substances (EPS) secreted by the microalga Graesiella emersonii KNUA204, highlighting the potential of microalgal biomolecules in nanotechnology. EPS-rich supernatant from G. emersonii enabled AgNP formation under light without the need for biomass pre-processing. The effects of culture age, pH (optimal at 10-11), and tetracycline as a secondary stabilizer were examined. Tetracycline accelerated AgNP formation in dark conditions but could not fully substitute light-induced reduction. The synthesized AgNPs and tetracycline-assisted AgNPs (Tetra-AgNPs) were characterized using UV-visible spectroscopy, EDX, XRD, FTIR, TEM, and Zeta potential measurements, confirming their crystalline, spherical, and moderately stable properties. Biological assays showed strong antibacterial activity at 10 mu g mL-1, though Tetra-AgNPs did not outperform AgNPs or tetracycline alone, suggesting structural incorporation of tetracycline. Both AgNPs and Tetra-AgNPs showed similar antioxidant activity. These findings support the potential of G. emersonii KNUA204 for dual biomass utilization, integrating biofuel production with nanomaterial synthesis. Further optimization of EPS composition and biosynthesis conditions could enhance nanoparticle properties for biomedical and environmental applications, reinforcing microalgae as a platform for sustainable nanotechnology. ⓘ Do, Jeong-Mi; Hong, Ji Won; Yoon, Ho-Sung ⓘ Kyungpook Natl Univ, Integrated Blue Carbon Res Ctr, Adv Bioresource Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, FOUR KNU Creat Biores Grp BK21, Daegu, South Korea ⓘ ⓘ 57208562245; 57201579963; 7402990205 ⓘ hsy@knu.ac.kr; ⓘ FRONTIERS IN MICROBIOLOGY ⓘ FRONT MICROBIOL ⓘ 1664-302X 16 SCIE MICROBIOLOGY ⓘ 2024 4.5 23.0 0 2025-06-11 ⓘ 0 0 microalgae; nanoparticles; biosynthesis; sustainability; tetracycline ⓘ EPS ⓘ biosynthesis; microalgae; nanoparticles; sustainability; tetracycline ⓘ biofuel; nanoparticle; silver nanoparticle; tetracycline; antibacterial activity; antioxidant activity; Article; bacterial strain; biomass; biosynthesis; controlled study; DNA extraction; energy consumption; energy dispersive X ray spectroscopy; environmental sustainability; Escherichia coli; Fourier transform infrared spectroscopy; Graesiella emersonii; high performance liquid chromatography; inductively coupled plasma atomic emission spectrometry; light intensity; microalga; nanobiotechnology; nanotechnology; nonhuman; pH; photosynthesis; Staphylococcus aureus; transmission electron microscopy; ultraviolet spectroscopy; X ray diffraction; zeta potential ⓘ English 2025 2025-05-14 10.3389/fmicb.2025.1589285 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Robust prediction-based control for unknown time-varying delays and disturbances in spherical motion platform ⓘ This paper presents a new prediction-based controller utilizing enhanced preview and state prediction methods to deal with unknown time-varying delays and disturbances. In practice, uncertain and variable time delays in virtual reality applications can lead to control instability and a significant reduction in the overall sense of realism. In this paper, a robust prediction-based control (RPC) is proposed for the spherical motion platform (SMP) to compensate for the effects of the time-varying delays and disturbances. The RPC comprises a preview strategy and state/disturbance prediction methods with an estimator to handle unknown time-varying delays. In addition, a newly proposed preview method improves the system's ability to follow a time-varying reference trajectory. The stability analysis for the time-delayed system incorporating the RPC is conducted using the Lyapunov-Krasovskii approach. Numerical simulations and various experiments demonstrate that the RPC effectively leads the state to converge to the desired trajectory within an error bound under various conditions of time-varying delays in the presence of disturbances, whereas the existing controllers have limitations in reducing the desired control errors. Consequently, the results validate the feasibility and effectiveness of the RPC in real-world applications, demonstrating its robustness in handling time-varying delays through practical implementation on the SMP. ⓘ Lee, Seong-Min; Lee, Sangheon; Son, Hungsun ⓘ Jeju Natl Univ, Dept Mech Syst Engn, Jeju 63243, South Korea; Jeju Natl Univ, Major Mechatron Engn, Jeju 63243, South Korea; Jeju Natl Univ, Fac Appl Energy Syst, Jeju 63243, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol, Dept Mech Engn, Ulsan 44919, South Korea ⓘ ⓘ 56544731100; 57192193460; 56346553800 ⓘ leesm128@jejunu.ac.kr; ssle8653@knu.ac.kr; hson@unist.ac.kr; ⓘ CONTROL ENGINEERING PRACTICE ⓘ CONTROL ENG PRACT ⓘ 0967-0661 1873-6939 163 SCIE AUTOMATION & CONTROL SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC ⓘ 2024 4.6 23.0 0 2025-06-11 ⓘ 0 0 Lyapunov-Krasovskii functional; Prediction-based control; Preview trajectory; Unknown time-varying delay ⓘ LTI SYSTEMS; INPUT ⓘ Lyapunov–Krasovskii functional; Prediction-based control; Preview trajectory; Unknown time-varying delay ⓘ Delay-sensitive applications; Robust control; Lyapunov-Krasovskii's functional; Motion platforms; Prediction-based; Prediction-based control; Preview trajectory; Robust predictions; Spherical motion; Time-varying delay; Time-varying disturbance; Unknown time-varying delays; Robustness (control systems) ⓘ English 2025 2025-10 10.1016/j.conengprac.2025.106400 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Prediction of spatial-temporal flood water level in agricultural fields using advanced machine learning and deep learning approaches ⓘ Agricultural fields frequently experience flood disasters and significantly impacting food security, thus prompting the urgent need for efficient predictive flood mitigation mechanisms. This study presents an innovative approach for predicting spatial-temporal water levels in an agricultural field. Five ensemble machine-learning algorithms were developed to predict temporal channel water levels at four gauging points (GPs). Further, the ensemble Recurrent Neural Network - Long Short-Term Memory (RNN-LSTM), a deep learning-based model was employed for spatial prediction - surface water level. The models were trained and validated using observed rainfall and simulated water level data for both drainage and field surfaces derived from SWMM-based hydrological models. The Random Forest and Extra trees models achieved superior performance in temporal predictions at gauging points 1 and 4, achieving R-2 and KGE values greater than 0.800. For the spatial inundation predictions, the RNN-LSTM achieved R2 and RMSE values of 0.999 and 0.094, respectively. This study underscores the critical influence of drainage network characteristics and design rainfall patterns in enhancing flood prediction accuracy.

○ ○ Article ⓘ Design and analysis of quasi-vertical multi-fin GaN power devices based on epitaxially grown GaN-on-sapphire ⓘ This study presents the design and analysis of a quasi-vertical multi-fin gallium nitride (GaN) power device based on GaN-on-sapphire epitaxy, simulated using three-dimensional technology computer-aided design. The proposed structure aims to overcome the limitations of lateral high-electron-mobility transistors for high-power applications, as well as to address the cost issues associated with fully vertical GaN structures. Device optimization began with a single-fin structure and progressed incrementally. First, we determined the optimal doping concentration for n-type GaN in the drift region and channel, followed by the application and analysis of the trench drain, source field plate, and multi-fin structures. The optimized device achieves impressive performance, with a specific on-resistance of 0.85 m Omega cm2, a breakdown voltage of 1263 V, and a Baliga's figure of merit of 1.87 GW cm-2. This study's systematic optimization and structural analysis provide valuable insights into enhancing device characteristics for high-power semiconductor applications and contribute to a deeper understanding of the electrical properties of quasi-vertical fin-type power devices. ⓘ Hong, Jeong Woo; Lee, Sang Ho; Park, Jin; Kim, Min Seok; Bae, Seung Ji; Koh, Won Suk; San Yun, Gang; Kang, In Man ⓘ Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea ⓘ Lee, Sang Ho/MCX-8396-2025; Kim, Min-Seok/LZH-3686-2025 ⓘ 58485369700; 57416738400; 57376422900; 59073001500; 58485369600; 59508365800; 59507956800; 7203062678 ⓘ imkang@ee.knu.ac.kr; ⓘ JOURNAL OF SCIENCE-ADVANCED MATERIALS AND DEVICES ⓘ J SCI-ADV MATER DEV ⓘ 2468-2284 2468-2179 10 1 SCIE MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY ⓘ 2024 6.8 23.2 0 2025-05-07 ⓘ 0 0 Quasi-vertical structure; Gallium nitride (GaN); Power device; Fin structure; Baliga's figure of merit ⓘ TRANSISTORS; PERFORMANCE; HEMT ⓘ Baliga's figure of merit; Fin structure; Gallium nitride (GaN); Power device; Quasi-vertical structure ⓘ ⓘ English 2025 2025-03 10.1016/j.jsamd.2025.100848 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Molecular surveillance of antifolate drug resistance markers in Plasmodium vivax from Khyber Pakhtunkhwa province, northwest Pakistan ⓘ The emergence and spread of antimalarial drug resistance pose significant challenges in the fight against malaria. Mutations in dihydrofolate reductase (DHFR) and dihydropteroate synthetase (DHPS) in Plasmodium vivax are associated with sulfadoxine-pyrimethamine (SP) drug resistance. This study assessed SP resistance status in P. vivax isolates collected in Khyber Pakhtunkhwa province, Pakistan, by analyzing mutations in pvdhfr and pvdhps. Both genes were successfully amplified concurrently from 112 Pakistan P. vivax isolates. Sequence analysis of pvdhfr indicated that mutations F57L, S58R, and S117N were present with frequencies of 0.9 %, 31.3 %, and 46.4 %, respectively. The predominant wild-type haplotype F57S58T61S117 was identified in 51.8 % of samples, whereas mutant haplotypes were also detected: F57R58T61N117 (29.5 %), F57S58T61N117 (16.9 %), F57R58T61S117 (0.9 %), and L57R58T61S117 (0.9 %). In pvdhps, the sole mutation A383 G was found at a low frequency of 1.8 %, leading to a mutant haplotype S382G383K512A553V585. The integrated analysis of pvdhfr and pvdhps haplotypes showed that the wild-type haplotype was the most prevalent (50.9 %), followed by mutant haplotypes F57R58T61N117/ S382A383K512A553V585 (28.6 %) and F57S58T61N117/S382A383K512A553V585 (16.9 %). These findings indicate a relatively low level of antifolate resistance in Pakistan P. vivax isolates, suggesting that Pakistan P. vivax may still be amenable to SP treatment. Nevertheless, the persistence of similar mutation rates and patterns associated with SP resistance in the Pakistan pvdhfr and pvdhps populations, despite the absence of current SP pressure, underscores the importance of ongoing monitoring of SP resistance in the Pakistan P. vivax population. ⓘ Nguyen, Thu Hang; Le, Huong Giang; Vo, Tuaan Cuong; Nguyen, Dang Thuy Duong; Nguyen, Kim Oanh; Cho, Minkyoung; Goo, Youn-Kyoung; Afridi, Sahib Gul; Na, Byoung-Kuk ⓘ Gyeongsang Natl Univ, Coll Med, Dept Parasitol & Trop Med, Jinju 52727, South Korea; Gyeongsang Natl Univ, Dept Convergence Med Sci, Jinju 52727, South Korea; Kyungpook Natl Univ, Sch Med, Dept Parasitol & Trop Med, Daegu 41944, South Korea; Abdul Wali Khan Univ Mardan, Dept Biochem, Khyber Pakhtunkhwa 23200, Pakistan ⓘ Afridi, Sahib/AGH-9949-2022 ⓘ 58746295600; 57200567418; 57216850499; 58902858800; 59354493200; 59355724800; 22937863200; 36607439500; 7005291099 ⓘ thuhang3399@gmail.com; gianglee291994@gmail.com; vtcuong241@gmail.com; duongnguyenhcm1103@gmail.com; nguyenkimoanh280918@gmail.com; mcho@gnu.ac.kr; kuku1819@knu.ac.kr; drafridi@awkum.edu.pk; bkna@gnu.ac.kr; ⓘ ACTA TROPICA ⓘ ACTA TROP ⓘ 0001-706X 1873-6254 264 SCIE PARASITOLOGY;TROPICAL MEDICINE ⓘ 2024 2.5 23.2 0 2025-05-07 ⓘ 0 0 Plasmodium vivax; Antifolate drug resistance; pvdhfr; pvdhps; Pakistan ⓘ DIHYDROFOLATE-REDUCTASE; SULFADOXINE-PYRIMETHAMINE; DIHYDROPTEROATE SYNTHASE; AMINO-ACID; MUTATIONS; DHFR; GENES; DHPS; SULFADOXINE/PYRIMETHAMINE; CHLOROQUINE ⓘ Antifolate drug resistance; Pakistan; Plasmodium vivax; pvdhfr; pvdhps ⓘ Adolescent; Adult; Antimalarials; Child; Child, Preschool; Dihydropteroate Synthase; DNA, Protozoan; Drug Combinations; Drug Resistance; Female; Folic Acid Antagonists; Haplotypes; Humans; Malaria, Vivax; Male; Middle Aged; Mutation, Missense; Pakistan; Peptide Synthases; Plasmodium vivax; Pyrimethamine; Sequence Analysis, DNA; Sulfadoxine; Tetrahydrofolate Dehydrogenase; Young Adult; Khyber-Pakhtunkhwa; Pakistan; alanine; arginine; asparagine; dihydrofolate reductase; dihydropteroate synthase; folic acid antagonist; leucine; phenylalanine; serine; valine; antimalarial agent; dihydrofolate reductase; dihydrofolate synthetase; dihydropteroate synthase; fanasil, pyrimethamine drug combination; folic acid antagonist; peptide synthase; protozoal DNA; pyrimethamine; sulfadoxine; drug resistance; molecular analysis; mutation; parasite; protozoan; antimalarial drug resistance; Article; blood sampling; controlled study; gene; gene amplification; gene identification; gene mutation; gene sequence; haplotype; molecular surveillance; monitoring; mutant; mutation rate; nonhuman; nucleotide sequence; Pakistan; parasite isolation; Plasmodium vivax; Plasmodium vivax malaria; pvdhfr gene; pvdhps gene; sequence analysis; single nucleotide polymorphism; adolescent; adult; chemistry; child; DNA sequencing; drug combination; drug effect; drug resistance; epidemiology; female; genetics; human; isolation and purification; male; middle aged; missense mutation; Pakistan; parasitology; Plasmodium vivax malaria; preschool child; young adult ⓘ English 2025 2025-04 10.1016/j.actatropica.2025.107583 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Optimizing the analysis of emission lines in galaxies: the case of the MUSE TIMER galaxy NGC 613 ⓘ Galaxy evolution is driven by spatially distributed processes with varying time-scales. Integral field spectroscopy provides spatially resolved information about these processes. Nevertheless, disentangling these processes, which are related to both the underlying stellar populations and the interstellar medium can be challenging. We present a case study on NGC 613, observed with MUSE (Multi-Unit Spectroscopic Explorer) for the TIMER (Time Inference with MUSE in Extragalactic Rings) project, a local barred galaxy, which shows several gas ionization mechanisms and is rich in both large and inner-scale stellar structures. We develop a set of steps to overcome fundamental problems in the modelling of emission lines with multiple components, together with the characterization of the stellar populations. That results in the disentanglement of the gas ionization mechanisms and kinematics, along with an optimal parametrization for star formation history recovery. Our analysis reveals evidence of gas inflows, which are associated with the bar dust lanes traced with Hubble Space Telescope. In addition, we show the gas kinematics in a central biconical outflow, which is aligned with a radio jet observed with Very Large Array. The emission line provides estimates of electron density, gas-phase metallicity, and the mass outflow rate, allowing us to distinguish intertwined ionization mechanisms and to identify a part of the multiphase gas cycle in NGC 613. It traces the gas kinematics from the bar lanes to inner scale gas reservoirs, where it can eventually trigger star formation or AGN activity, as observed in the outflow. ⓘ Silva-Lima, Luiz A; Gadotti, Dimitri A; Martins, Lucimara P; Kolcu, Tutku; Coelho, Paula R T; Fragkoudi, Francesca; Kim, Taehyun; de Sa-Freitas, Camila; Falcon-Barroso, Jesus; de Lorenzo-Caceres, Adriana; Mendez-Abreu, Jairo; Neumann, Justus; Querejeta, Miguel; Sanchez-Blazquez, Patricia ⓘ Univ Cidade Sao Paulo, Nucleo Astrofis, Rua Galvao Bueno 868, BR-01506000 Sao Paulo, Brazil; Durham Univ, Ctr Extragalact Astron, Dept Phys, South Rd, Durham DH1 3LE, England; Liverpool John Moores Univ, Astrophys Res Inst, IC2 Liverpool Sci Pk,146 Brownlow Hill, Liverpool L3 5RF, England; Univ Nottingham, Sch Phys & Astron, Univ Pk, Nottingham NG7 2RD, England; Univ Sao Paulo, Inst Astron Geofis & Ciencias Atmosfer, Rua Matao 1226, BR-05508090 Sao Paulo, SP, Brazil; Durham Univ, Inst Computat Cosmol, Dept Phys, South Rd, Durham DH1 3LE, England; Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 41566, South Korea; European Southern Observ, Alonso Cordova 3107, Vitacura, Region Metropolitana, Chile; Univ La Laguna, Dept Astrofis, Av Astrofisico Francisco Sanchez S-N, E-38206 La Laguna, Tenerife, Spain; Inst Astrofis Canarias, C Via Lactea S-N, E-38205 La Laguna, Tenerife, Spain; Max Planck Inst Astron, Konigstuhl 17, D-69117 Heidelberg, Germany; Observ Astron Nacl, C Alfonso XII 3, E-28014 Madrid, Spain; Univ Complutense Madrid, Dept Fis Tierra & Astrofis, E-28040 Madrid, Spain; Univ Complutense Madrid, Inst Fis Particulas & Cosmos IPARCOS, E-28040 Madrid, Spain ⓘ Lima, Luiz/HRA-3630-2023; Falcon-Barroso, Jesus/AAD-9660-2019; Querejeta, Miguel/KVY-3638-2024 ⓘ 57554553900; 55887354100; 23088660100; 57222207305; 23011441600; 55062198600; 57050549000; 57211524578; 6602632408; 23088009300; 23051261000; 56514665700; 35424450700; 16319840900 ⓘ luiz.sl@outlook.com; ⓘ MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY ⓘ MON NOT R ASTRON SOC ⓘ 0035-8711 1365-2966 540 3 SCIE ASTRONOMY & ASTROPHYSICS ⓘ 2024 4.8 23.2 ⓘ 0 0 ISM: jets and outflows; ISM: kinematics and dynamics; galaxies: evolution; galaxies: star formation; galaxies: structure ⓘ ACTIVE GALACTIC NUCLEUS; DIGITAL SKY SURVEY; STELLAR POPULATION SYNTHESIS; DOUBLE-BARRED GALAXIES; CENTRAL MOLECULAR ZONE; DATA-ANALYSIS PIPELINE; STAR-FORMATION; SPITZER SURVEY; BOXY/PEANUT BULGES; SAURON PROJECT ⓘ galaxies: evolution; galaxies: star formation; galaxies: structure; ISM: jets and outflows; ISM: kinematics and dynamics ⓘ Astrophysics; Density of gases; Fighter aircraft; Galaxies; Gases; Integral equations; Ionization of gases; Kinematics; Stars; Emission lines; Galaxies: star formation; Galaxies:structure; Galaxy evolution; Inner scale; Ionization mechanisms; ISM jets and outflows; ISM: Kinematics and dynamics; Multi-unit; Stellar populations; Electromagnetic wave emission ⓘ English 2025 2025-07 10.1093/mnras/staf837 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Prevalence and zoonotic potential of pathogens in micromammals (rodents and insectivores) in the Republic of Korea ⓘ Micromammals (rodents and insectivores), are reservoirs of numerous zoonotic pathogens and play a critical role in infectious disease transmission. The rising prevalence of micromammals-associated pathogens in the Republic of Korea highlights the urgent need for targeted surveillance. Here, we analyzed micromammal blood samples collected from 16 nationwide sites during spring 2022, autumn 2022, and spring 2023 to investigate the following key zoonotic diseases: severe fever with thrombocytopenia syndrome, Lyme disease, Q fever, scrub typhus, anaplasmosis, ehrlichiosis, and rickettsioses. Our analysis revealed that of the 756 micromammal samples analyzed, 0.1 % had Borrelia afzelii, Borrelia valaisiana, and Orientia tsutsugamushi, 12.7 % contained Ana-plasma phagocytophilum, and 82 % Neoehrlichia mikurensis. Importantly, we detected Borrelia valaisiana in micromammals in the Republic of Korea for the first time. Phylogenetic analysis identified close genetic links between local and global pathogen strains, highlighting potential cross-border transmission risks. The high prevalence of Neoehrlichia mikurensis emphasizes the zoonotic threat of micromammals. These findings provide crucial insights about enhancing micromammals-associate pathogen surveillance, inform public health strategies, and reinforce the importance of monitoring micromammal populations for zoonotic infection risk mitigation in Korea and beyond. ⓘ Kim, Beoul; Lee, You-Jeong; Choi, Insu; Kang, Yong-Myung; Kwak, Dongmi; Seo, Min-Goo ⓘ Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Vet Biomed Sci, Daegu 41566, South Korea ⓘ Seo, Min-Goo/NQF-4335-2025 ⓘ 59343608800; 59343760600; 59830304200; 59831142800; 7007148758; 58950739700 ⓘ koreasmg@knu.ac.kr; ⓘ ACTA TROPICA ⓘ ACTA TROP ⓘ 0001-706X 1873-6254 266 SCIE PARASITOLOGY;TROPICAL MEDICINE ⓘ 2024 2.5 23.2 N/A ⓘ 1 1 Micromammals; Borrelia; Orientia tsutsugamushi; Anaplasma; Neoehrlichia; Zoonotic diseases ⓘ CANDIDATUS NEOEHRLICHIA-MIKURENSIS; BURGDORFERI SENSU-LATO; BORRELIA-VALAISIANA; IDENTIFICATION; EHRLICHIA; ANAPLASMA; FEVER ⓘ Anaplasma; Borrelia; Micromammals; Neoehrlichia; Orientia tsutsugamushi; Zoonotic diseases ⓘ Animals; Borrelia; Disease Reservoirs; Humans; Phylogeny; Prevalence; Republic of Korea; Rodentia; Zoonoses; South Korea; blood; disease prevalence; disease transmission; health monitoring; health risk; insectivore; pathogen; plasma; public health; reservoir; rodent; sampling; Anaplasma phagocytophilum; anaplasmosis; Apodemus agrarius; Apodemus peninsulae; Article; autumn; bacterium; blood sampling; Borrelia; Borrelia afzelii; Borrelia valaisiana; Craseomys regulus; Craseomys rufocanus; Crocidura dobson; Crocidura lasiua; disease severity; disease surveillance; disease transmission; ehrlichiosis; fever; genetic linkage; infection risk; infectious agent; Insectivora; insectivore; Lyme disease; Micromys minutus; Microtus fortis; Mogera robust; Myodes regulus; Neoehrlichia mikurensis; nonhuman; Orientia tsutsugamushi; phylogeny; prevalence; Q fever; rickettsiosis; rodent; scrub typhus; South Korea; spring; thrombocytopenia; zoonosis; animal; disease reservoir; epidemiology; genetics; human; isolation and purification; microbiology; prevalence ⓘ English 2025 2025-06 10.1016/j.actatropica.2025.107649 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Recycling waste for energy: Reusing methyl orange dye-adsorbed polythiophene/Fe3O4 nanorods/reduced graphene oxide nanocomposite as a supercapacitor electrode ⓘ This study presents a sustainable waste-to-wealth approach by repurposing methyl orange (MO) dye-adsorbed polythiophene/iron oxide/reduced graphene oxide nanocomposite (PTh/Fe3O4/RGO) for dual functionality in wastewater treatment and energy storage. PTh/Fe3O4/RGO nanocomposite was initially employed as an effective adsorbent to remove harmful MO dye from wastewater. After successful adsorption, the dye-saturated PTh/ Fe3O4/RGO was repurposed as a supercapacitor electrode to investigate its energy storage capabilities. Electrochemical tests before MO adsorption revealed that the pristine PTh/Fe3O4/RGO electrode demonstrated promising performance with a specific capacitance of 467.3 Fg- 1 at 1 Ag- 1 and excellent cyclic stability of 95.3% retention over 5000 Galvanostatic charge-discharge (GCD) cycles. Further, the maximum adsorption of MO by the PTh/Fe3O4/RGO was achieved under optimal conditions: pH 3, 2.5 gL- 1 dosage, 120 min contact time, and 50 mgL- 1 MO concentration. The adsorption behaviour was well-explained by the Langmuir isotherm, pseudosecond-order kinetics, and Dubinin-Radushkevich (D-R) isotherm, indicating a physical adsorption process with a monolayer capacity of 151.34 mgg-1. Thermodynamic analysis, with a positive enthalpy (Delta H degrees) and negative Gibbs free energy (Delta G degrees), confirmed that the process is endothermic and spontaneous. Desorption studies showed that 88.72% of the MO could be desorbed in the first cycle, with effective regeneration up to six cycles using NaOH. Post-adsorption, the material still retained significant supercapacitor properties, with a specific capacitance of 380.9 Fg- 1 at 1 Ag- 1 and 83.2% cyclic stability over 5000 GCD cycles. This study demonstrates a circular, sustainable approach that integrates waste treatment with energy storage, highlighting the potential of reusing materials for multifunctional applications. ⓘ Husain, Ahmad; Ali, Asim; Alqarni, Sara A.; Ansari, Khalid; Danish, Mohtaram; Gunnasegaran, Prem; Kanan, Mohammad; Giri, Jayant; Kandasamy, M.; Khan, M.

○ ○ Article ⓘ Component Associations of the Healthy Worker Survivor Bias in Medical Radiation Workers ⓘ BackgroundThe healthy worker survivor bias may vary by sex. This study investigated three component associations necessary for this bias to determine the origins of sex differences in this bias among male and female workers.MethodsWe analyzed a data set of 93,918 South Korean diagnostic medical radiation workers registered in the National Dose Registry from 1996 to 2011, linked with mortality and cancer incidence data. Component associations were assessed using Cox regression to estimate hazard ratios (HRs) and logistic regression with generalized estimating equations to estimate odds ratios (ORs).ResultsA significant association between prior cumulative exposure and employment status was observed for all-cause mortality in male (HR 1.06, 95% CI 1.02-1.10), whereas an inverse association was noted in female workers (HR 0.82, 95% CI 0.78-0.87). Adjusted ORs for employment status and subsequent exposure for all-cause mortality, as well as HRs for employment status and survival time, demonstrated associations in the same direction in both males and females.ConclusionsOur findings demonstrate that sex-specific differences in healthy worker survivor bias were primarily driven by the association between prior exposure and employment status. To improve bias mitigation in occupational cohort studies, sex-specific components should be incorporated. ⓘ Lee, Won Jin; Jeong, Jaeho; Kim, Young Min ⓘ Korea Univ, Coll Med, Dept Prevent Med, Seoul, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea ⓘ ⓘ 55641918400; 59358304100; 59510684400 ⓘ leewj@korea.ac.kr; ⓘ AMERICAN JOURNAL OF INDUSTRIAL MEDICINE ⓘ AM J IND MED ⓘ 0271-3586 1097-0274 68 6 SCIE PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH ⓘ 2024 3.1 23.3 0 2025-05-07 ⓘ 0 0 bias; cohort; health professionals; ionizing radiation; occupational exposure ⓘ LUNG-CANCER MORTALITY; EMPLOYMENT; AUTOWORKERS; EXPOSURE; MODELS ⓘ bias; cohort; health professionals; ionizing radiation; occupational exposure ⓘ Adult; Aged; Bias; Employment; Female; Healthy Worker Effect; Humans; Logistic Models; Male; Middle Aged; Occupational Exposure; Odds Ratio; Proportional Hazards Models; Registries; Republic of Korea; Sex Factors; Survivors; adult; adverse event; aged; employment; epidemiology; female; healthy worker effect; human; male; middle aged; occupational exposure; odds ratio; proportional hazards model; register; sex factor; South Korea; statistical bias; statistical model; survivor ⓘ English 2025 2025-06 10.1002/ajim.23727 ⓘ 바로가기 바로가기 바로가기 바로가기
