| ○ | ○ | Article | Workload of Healthcare Workers During the COVID-19 Outbreak in Korea: A Nationwide Survey | Background: As the coronavirus disease 2019 (COVID-19) pandemic is ongoing, heavy workload of healthcare workers (HCWs) is a concern. This study investigated the workload of HCWs responding to the COVID-19 outbreak in South Korea. Methods: A nationwide cross-sectional survey was conducted from September 16 to October 15, 2020, involving 16 healthcare facilities (4 public medical centers, 12 tertiary-care hospitals) that provide treatment for COVID-19 patients. Results: Public medical centers provided the majority (69.4%) of total hospital beds for COVID-19 patients (n = 611), on the other hand, tertiary care hospitals provided the majority (78.9%) of critical care beds (n = 57). The number of beds per doctor (median [IQR]) in public medical centers was higher than in tertiary care hospitals (20.2 [13.0, 29.4] versus 3.0 [1.3, 6.6], P = 0.006). Infectious Diseases physicians are mostly (80%) involved among attending physicians. The number of nurses per patient (median [interquartile range, IQR]) in tertiary care hospitals was higher than in public medical centers (4.6 [3.4-5] vs. 1.1 [0.8-2.1], P = 0.089). The median number of nurses per patient for COVID-19 patients was higher than the highest national standard in South Korea (3.8 vs. 2 for critical care). All participating healthcare facilities were also operating screening centers, for which a median of 2 doctors, 5 nurses, and 2 administrating staff were necessary. Conclusion: As the severity of COVID-19 patients increases, the number of HCWs required increases. Because the workload of HCWs responding to the COVID-19 outbreak is much greater than other situations, a workforce management plan regarding this perspective is required to prevent burnout of HCWs. | Cheong, Hae Suk; Kwon, Ki Tae; Hwang, Soyoon; Kim, Shin-Woo; Chang, Hyun-Ha; Park, Se Yoon; Kim, Bongyoung; Lee, Shinwon; Park, Jiho; Heo, Sang Taek; Oh, Won Sup; Kim, Yeonjae; Park, Kyung-Hwa; Kang, Chang Kyung; Oh, NamHee; Lim, Su Jin; Yun, Seongcheol; Son, Ji Woong | Sungkyunkwan Univ, Kangbuk Samsung Hosp, Dept Internal Med, Div Infect Dis,Sch Med, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Div Infect Dis,Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Div Infect Dis,Dept Internal Med, Daegu, South Korea; Soonchunhyang Univ, Coll Med, Seoul Hosp, Div Infect Dis,Dept Internal Med, Seoul, South Korea; Hanyang Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Pusan Natl Univ, Sch Med, Dept Internal Med, Busan, South Korea; Pusan Natl Univ Hosp, Med Res Inst, Busan, South Korea; Konkuk Univ, Sch Med, Dept Internal Med, Med Ctr, Seoul, South Korea; Jeju Natl Univ, Coll Med, Dept Internal Med, Div Infect Dis, Jeju, South Korea; Kangwon Natl Univ, Dept Internal Med, Div Infect Dis, Sch Med, Chunchon, South Korea; Natl Med Ctr, Dept Internal Med, Div Infect Dis, Seoul, South Korea; Chonnam Natl Univ Med Sch, Dept Infect Dis, Gwangju, South Korea; Seoul Natl Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Daegu Med Ctr, Hosp Infect Control Team, Daegu, South Korea; Masan Med Ctr, Dept Internal Med, Div Resp Dis, Chang Won, South Korea; Andong Med Ctr, Dept Internal Med, Andong, South Korea; Konyang Univ Hosp, Dept Internal Med, Daejeon, South Korea | Kim, Hanjin/KYP-2633-2024; Kim, Sooyeon/AAA-8521-2022; Kim, Woo/AAG-1822-2019; Kim, Bongyoung/H-3409-2018; Lee, Eun/J-2780-2012; Hwang, Soyoon/HHM-5762-2022 | 57233155100; 9733850500; 57203160675; 8710731500; 7407521688; 55259986400; 55622077200; 24479446100; 57452625000; 9737963500; 24778642500; 56066688300; 57219637574; 55808491400; 57195674103; 57222279275; 57218948065; 57217473793 | ktkwon@knu.ac.kr; | JOURNAL OF KOREAN MEDICAL SCIENCE | J KOREAN MED SCI | 1011-8934 | 1598-6357 | 37 | 6 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 4.5 | 28.1 | 3.99 | 2025-06-25 | 24 | 25 | SARS-CoV-2; Health Workforce; Burnout; Health Facilities | Burnout; Health facilities; Health workforce; Sars-cov-2 | COVID-19; Cross-Sectional Studies; Health Facilities; Health Personnel; Humans; Republic of Korea; SARS-CoV-2; Surveys and Questionnaires; Workload; cross-sectional study; epidemiology; health care facility; health care personnel; human; questionnaire; South Korea; workload | English | 2022 | 2022-02-14 | 10.3346/jkms.2022.37.e49 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | COMPARISON OF SURGEON MUSCULAR PROPERTIES BETWEEN STANDARD OPERATING MICROSCOPE AND DIGITALLY ASSISTED VITREORETINAL SURGERY SYSTEMS | Purpose: To quantitatively analyze surgical ergonomics between standard operating microscope (SOM) and digitally assisted vitreoretinal surgery (DAVS) systems. Methods: The surgeon conducted procedures on 110 patients; 52 patients underwent a combined phacoemulsification and pars plana vitrectomy (Phaco-PPV group, 24 using SOM and 28 using DAVS), and 58 patients underwent phacoemulsification (Phaco group, 30 using SOM and 28 using DAVS). The surgeon's muscle tone and stiffness in the sternocleidomastoid and the two positions of the upper trapezius (UT), which are 2-cm intervals along the UT muscle fibers, UT1 and UT2, were measured at preoperative, intraoperative, and postoperative time points. Results: In the Phaco-PPV group using the SOM, intraoperative muscle tone and stiffness were higher than preoperative and postoperative values in the sternocleidomastoid (P 0.05). Conclusion: This study provides quantitative measurement of retina surgeon ergonomics, suggesting that compared with a SOM, the DAVS can reduce intraoperative muscle fatigue. | Park, Su Jin; Hwang, Jong-Moon; Park, Eugene Jae Jin; Shin, Jae Pil; Park, Dong Ho | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Ophthalmol, Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Rehabil Med, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Orthopaed Surg, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Biomed Res Inst, Daegu, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu, South Korea | Park, Eugene/P-1473-2018 | 57194422330; 56367634000; 57827841600; 56517350400; 36676632900 | DongHo_Park@knu.ac.kr; | RETINA-THE JOURNAL OF RETINAL AND VITREOUS DISEASES | RETINA-J RET VIT DIS | 0275-004X | 1539-2864 | 42 | 8 | SCIE | OPHTHALMOLOGY | 2022 | 3.3 | 28.2 | 0.62 | 2025-06-25 | 3 | 3 | digitally assisted vitreoretinal surgery; ergonomics; muscle fatigue; muscle properties | VISCOELASTIC PROPERTIES; MUSCLE FATIGUE; HEAD POSTURE; STIFFNESS; FORCE; ELASTOGRAPHY; NECK; PAIN | digitally assisted vitreoretinal surgery; ergonomics; muscle fatigue; muscle properties | Cataract Extraction; Humans; Phacoemulsification; Retrospective Studies; Surgeons; Vitrectomy; Vitreoretinal Surgery; adult; aged; Article; controlled study; ergonomics; female; hand held myotonometer; human; intraoperative period; major clinical study; male; middle aged; muscle fatigue; muscle rigidity; muscle tone; observational study; outcome assessment; pars plana vitrectomy; phacoemulsification; postoperative period; preoperative evaluation; prospective study; quantitative analysis; skeletal muscle cell; sternocleidomastoid muscle; surgeon; trapezius muscle; cataract extraction; phacoemulsification; procedures; retrospective study; vitrectomy; vitreoretinal surgery | English | 2022 | 2022-08 | 10.1097/iae.0000000000003482 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Actinomucor elegans and Podospora bulbillosa Positively Improves Endurance to Water Deficit and Salinity Stresses in Tomato Plants | Fungal strains isolated from the rhizosphere of healthy Solanum lycopersicum were examined to mitigate symptoms of drought and salinity stresses. The fungal strains were identified as Actinomucor elegans and Podospora bulbillosa based on their DNA sequencing and morphological analysis. Additionally, the fungal strains were assayed for a number of plant growth promoting traits and abiotic stresses on solid media. Moreover, a greenhouse experiment was conducted and tomato seedlings were treated with 25% PEG or 1.5% NaCl for 12 days, and the impact of plant growth promoting fungi (PGPF) on tomato seedling performance under these conditions was examined. PGPF application raised the survival of the stressed tomato plants, which was evidenced by higher physiological and biochemical processes. The PGPF-inoculated plants exhibited higher chlorophyll, carotenoid, protein, amino acid, antioxidant activities, salicylic acid, glucose, fructose, and sucrose contents, and showed lower hydrogen peroxide, and lipid metabolism relative to control plants under stress. Analysis using gene expression showed enhanced expression of SlF3H gene and reduced expression of SlNCED1, SlDEAD31, SlbZIP38, and SlGRAS10 genes following PGPFs application. Overall, the outcomes of this study elucidate the function of these fungal strains and present candidates with potential implementation as biofertilizers and in promoting plant stress endurance. | Kazerooni, Elham Ahmed; Maharachchikumbura, Sajeewa S.

| ○ | ○ | Article | Immunomodulatory Molecular Mechanisms of Luffa cylindrica for Downy Mildews Resistance Induced by Growth-Promoting Endophytic Fungi | Downy mildew (DM), caused by P. cubensis, is harmful to cucurbits including luffa, with increased shortcomings associated with its control through cultural practices, chemical fungicides, and resistant cultivars; there is a prompt need for an effective, eco-friendly, economical, and safe biocontrol approach. Current research is therefore dealt with the biocontrol of luffa DM1 through the endophytic fungi (EF) consortium. Results revealed that T. harzianum (ThM9) and T. virens (TvA1) showed pathogen-dependent inducible metabolic production of squalene and gliotoxins by higher gene expression induction of SQS1/ERG9 (squalene synthase) and GliP (non-ribosomal peptide synthetase). Gene expression of lytic enzymes of EF was also induced with subsequently higher enzyme activities upon confrontation with P. cubensis. EF-inoculated luffa seeds showed efficient germination with enhanced growth potential and vigor of seedlings. EF-inoculated plants showed an increased level of growth-promoting hormone GA with higher gene expression of GA2OX8. EF-pre-inoculated seedlings were resistant to DM and showed an increased GSH content and antioxidant enzyme activities (SOD, CAT, POD). The level of MDA, H2O2, REL, and disease severity was reduced by EF. ACC, JA, ABA, and SA were overproduced along with higher gene expression of LOX, ERF, NCED2, and PAL. Expression of defense-marker genes (PPO, CAT2, SOD, APX, PER5, LOX, NBS-LRR, PSY, CAS, Ubi, MLP43) was also modulated in EF-inoculated infected plants. Current research supported the use of EF inoculation to effectively escalate the systemic immunity against DM corresponding to the significant promotion of induced systemic resistance (ISR) and systemic acquired resistance (SAR) responses through initiating the defense mechanism by SA, ABA, ET, and JA biosynthesis and signaling pathways in luffa. | Rauf, Mamoona; Ur-Rahman, Asim; Arif, Muhammad; Gul, Humaira; Ud-Din, Aziz; Hamayun, Muhammad; Lee, In-Jung | Abdul Wali Khan Univ Mardan, Dept Bot, Garden Campus, Mardan 23200, Pakistan; Abdul Wali Khan Univ Mardan, Dept Biotechnol, Garden Campus, Mardan 23200, Pakistan; Hazara Univ, Dept Biotechnol & Genet Engn, Mansehra 21120, Pakistan; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | ; rauf, mamoona/AAC-3246-2019; Hamayun, Muhammad/B-1694-2010; Rauf, Mamoona/AAC-3246-2019; Arif, Muhammad/GNM-5831-2022; Lee, In-Jung/GLS-0432-2022 | 55609311400; 57787514500; 57202654530; 7003592765; 57188860666; 59297330100; 16425830900 | mamoona@awkum.edu.pk;asimurrahman1@gmail.com;arif@awkum.edu.pk;gulhumaira@awkum.edu.pk;geneticsaz@gmail.com;hamayun@awkum.edu.pk;ijlee@knu.ac.kr; | JOURNAL OF FUNGI | J FUNGI | 2309-608X | 8 | 7 | SCIE | MICROBIOLOGY;MYCOLOGY | 2022 | 4.7 | 28.3 | 2.69 | 2025-06-25 | 23 | 23 | Luffa cylindrica; Pseudoperonospora cubensis; downy mildew; Trichoderma virens; Trichoderma harzianu; endophytic fungi; biocontrol | PHENYLALANINE AMMONIA-LYASE; TRICHODERMA-HARZIANUM; SYSTEMIC RESISTANCE; CELL-WALLS; BIOSYNTHESIS; PLANTS; STRESS; GENE; CHITINASE; SYNTHASE | biocontrol; downy mildew; endophytic fungi; Luffa cylindrica; Pseudoperonospora cubensis; Trichoderma harzianu; Trichoderma virens | English | 2022 | 2022-07 | 10.3390/jof8070689 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Laser-Induced Hydrothermal Growth of Iron Oxide Nanoparticles on Diverse Substrates for Flexible Micro-Supercapacitors | State-of-the-art microdevice fabrication requires patterned growth of functional nanomaterials on the desired position of the desired substrate. However, it is challenging, particularly in conventional hydrothermal synthesis, due to difficulties generating a local high-temperature field at the desired place. We introduce a laser-induced hydrothermal growth (LIHG) process for the rapid and selective synthesis of iron oxide nanoparticles (NPs). The substrates absorb the laser energy to generate a local high-temperature field necessary for the growth of iron oxide NPs. On various substrates, a dome-like structure comprising many iron oxide NPs is selectively synthesized within a localized temperature field. The LIHG process has several advantages for iron oxide NP growth, including rapidity, seedless growth, substrate compatibility, position selectivity, and patterning availability. Using its advantages, the LIHG process is used to fabricate flexible micro-supercapacitors based on laser-carbonized colorless polyimide films with iron oxide NPs. | Kong, Heejung; Kim, Hyeonwoo; Hwang, Suwon; Mun, Jonghwan; Yeo, Junyeob | Kyungpook Natl Univ, Dept Phys, Novel Appl Nano Opt Lab, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | Yeo, Junyeob/I-1287-2013; Kong, Heejung/CAG-1032-2022 | 57552927300; 57223908123; 57211075602; 57555832500; 58692645200 | junyeob@knu.ac.kr; | ACS APPLIED NANO MATERIALS | ACS APPL NANO MATER | 2574-0970 | 5 | 3 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2022 | 5.9 | 28.3 | 1.49 | 2025-06-25 | 20 | 22 | iron oxide; nanoparticles; laser; laser-induced hydrothermal growth; flexible micro-supercapacitors | PERFORMANCE; GRAPHENE; NANOWIRE; CARBON; MICROSPHERES; DECORATION; LAYER; FILMS | flexible micro-supercapacitors; iron oxide; laser; laser-induced hydrothermal growth; nanoparticles | Hydrothermal synthesis; Iron oxides; Oxide films; Substrates; Supercapacitor; Temperature; Flexible micro-supercapacitor; Growth process; High temperature field; Hydrothermal growth; Laser induced; Laser-induced hydrothermal growth; Micro-device fabrication; Microsupercapacitors; Patterned growth; State of the art; Metal nanoparticles | English | 2022 | 2022-03-25 | 10.1021/acsanm.2c00049 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Marine Natural Product Antimycin A Suppresses Wheat Blast Disease Caused by Magnaporthe oryzae Triticum | The application of chemical pesticides to protect agricultural crops from pests and diseases is discouraged due to their harmful effects on humans and the environment. Therefore, alternative approaches for crop protection through microbial or microbe-originated pesticides have been gaining momentum. Wheat blast is a destructive fungal disease caused by the Magnaporthe oryzae Triticum (MoT) pathotype, which poses a serious threat to global food security. Screening of secondary metabolites against MoT revealed that antimycin A isolated from a marine Streptomyces sp. had a significant inhibitory effect on mycelial growth in vitro. This study aimed to investigate the inhibitory effects of antimycin A on some critical life stages of MoT and evaluate the efficacy of wheat blast disease control using this natural product. A bioassay indicated that antimycin A suppressed mycelial growth (62.90%), conidiogenesis (100%), germination of conidia (42%), and the formation of appressoria in the germinated conidia (100%) of MoT at a 10 mu g/mL concentration. Antimycin A suppressed MoT in a dose-dependent manner with a minimum inhibitory concentration of 0.005 mu g/disk. If germinated, antimycin A induced abnormal germ tubes (4.8%) and suppressed the formation of appressoria. Interestingly, the application of antimycin A significantly suppressed wheat blast disease in both the seedling (100%) and heading stages (76.33%) of wheat at a 10 mu g/mL concentration, supporting the results from in vitro study. This is the first report on the inhibition of mycelial growth, conidiogenesis, conidia germination, and detrimental morphological alterations in germinated conidia, and the suppression of wheat blast disease caused by a Triticum pathotype of M. Oryzae by antimycin A. Further study is required to unravel the precise mode of action of this promising natural compound for considering it as a biopesticide to combat wheat blast. | Paul, Sanjoy Kumar; Chakraborty, Moutoshi; Rahman, Mahfuzur; Gupta, Dipali Rani; Mahmud, Nur Uddin; Rahat, Abdullah Al Mahbub; Sarker, Aniruddha; Hannan, Md.

| ○ | ○ | Article | Risk Assessment of Heavy Metals Occurrence in Two Wild Edible Oyster Mushrooms (Pleurotus spp.) Collected from Rajaji National Park | This study aimed at assessing the concentration of six heavy metals (Cd, Cr, Cu, Fe, Mn, and Zn) in two wild edible oyster mushrooms (Pleurotus ostreatus and Pleurotus djamor) collected from Rajaji National Park in Haridwar, India. For this purpose, mushroom samples were collected from selected locations (forest, residential, tourist, industrial areas, and transportation activities) from June 2021 to July 2022 and subsequently analyzed for selected heavy metals using atomic absorption spectroscopy (AAS). Results showed that both Pleurotus spp. had significantly varying (p < 0.05) concentrations of heavy metals. However, P. ostreatus showed relatively higher concentration levels of these metals compared to P. djamor. The mean concentrations (mg/kg dry weight) of the Cd, Cr, Cu, Fe, Mn, and Zn in P. ostreatus and P. djamor were 0.10 and 0.08, 0.87 and 0.64, 16.19 and 14.77, 28.49 and 27.15, 9.93 and 8.73, and 18.15 and 15.76, respectively. As indicated by the multivariate analysis tools i.e., principal component analysis (PCA) and hierarchical cluster analysis (HCA), the locations near the residential, industrial, and transportation activities had higher concentration levels of heavy metals. Moreover, the health risk studies using the target hazard quotient (THQ < 1) showed no significant health risk as the consumption of both Pleurotus spp., except for at one location, had high-traffic activities. The findings of this study provide vital information about the occurrence of potentially toxic heavy metals in wild edible Pleurotus spp. in Rajaji National Park in Haridwar, India representing a safeguard for mushroom consumers. | Siric, Ivan; Kumar, Pankaj; Adelodun, Bashir; Abou Fayssal, Sami; Bachheti, Rakesh Kumar; Bachheti, Archana; Ajibade, Fidelis O.; Kumar, Vinod; Taher, Mostafa A.; Eid, Ebrahem M. | Univ Zagreb, Fac Agr, Svetosimunska 25, Zagreb 10000, Croatia; Gurukula Kangri Deemed Univ, Dept Zool & Environm Sci, Agroecol & Pollut Res Lab, Haridwar 249404, Uttarakhand, India; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240003, Nigeria; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 37224, South Korea; Univ Forestry, Fac Agron, Dept Agron, 10 Kliment Ohridski Blvd, Sofia 1797, Bulgaria; Lebanese Univ, Fac Agr, Dept Plant Prod, Beirut 1302, Lebanon; Addis Ababa Sci & Technol Univ, Coll Appl Sci, Dept Ind Chem, POB 16417, Addis Ababa, Ethiopia; Addis Ababa Sci & Technol Univ, Ctr Excellence Nanotechnol, POB 16417, Addis Ababa, Ethiopia; Graph Era Deemed Univ, Dept Environm Sci, Dehra Dun 248002, Uttarakhand, India; Fed Univ Technol Akure, Dept Civil & Environm Engn, PMB 704, Akure 340001, Nigeria; King Khalid Univ, Fac Sci & Arts, Biol Dept, Mohail Assir 61321, Saudi Arabia; Aswan Univ, Fac Sci, Bot Dept, Aswan 81528, Egypt; King Khalid Univ, Coll Sci, Biol Dept, Abha 61321, Saudi Arabia; Kafrelsheikh Univ, Fac Sci, Bot Dept, Kafr Al Sheikh 33516, Egypt | Kumar, P.Vinod/HKP-1552-2023; Adelodun, Bashir/O-2941-2018; bachheti, Archana/N-5749-2017; Ajibade, Fidelis O./D-7893-2019; Kumar, Dr. Vinod/K-9971-2016; Kumar, Pankaj/AAF-2231-2019; Bachheti, Rakesh/AAS-1513-2020; Abou Fayssal, Sami/ABF-6226-2020; Eid, Ebrahem/O-2723-2013; Ajibade, Fidelis/D-7893-2019 | 55233815400; 57281192700; 57193774482; 57218598581; 36623425100; 55437052500; 57190341647; 57200152850; 57192983622; 35794350700 | rs.pankajkumar@gkv.ac.in;ebrahem.eid@sci.kfs.edu.eg; | JOURNAL OF FUNGI | J FUNGI | 2309-608X | 8 | 10 | SCIE | MICROBIOLOGY;MYCOLOGY | 2022 | 4.7 | 28.3 | 2.93 | 2025-06-25 | 23 | 25 | food quality; forest biodiversity; health risk; metal elements; traditional foraging; wild mushrooms | VEGETABLES | food quality; forest biodiversity; health risk; metal elements; traditional foraging; wild mushrooms | English | 2022 | 2022-10 | 10.3390/jof8101007 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Spatial Assessment of Potentially Toxic Elements (PTE) Concentration in Agaricus bisporus Mushroom Collected from Local Vegetable Markets of Uttarakhand State, India | This study presents a spatial assessment of eight potentially toxic elements (PTE: Cd, Cr, Cu, Fe, Pb, Ni, Mn, and Zn) in white button (Agaricus bisporus J.E. Lange) mushroom samples collected from the local vegetable markets of Uttarakhand State, India. Fresh A. bisporus samples were collected from thirteen districts and fifteen sampling locations (M1-M15) and analyzed for the concentration of these PTE using atomic absorption spectroscopy (AAS). The results revealed that A. bisporus contained all eight selected PTE in all sampling locations. Based on the inverse distance weighted (IDW) interpolation, principal component (PC), and hierarchical cluster (HC) analyses, the areas with a plane geographical distribution showed the highest PTE concentrations in the A. bisporus samples as compared to those in hilly areas. Overall, the decreasing order of PTE concentration in A. bisporus was recognized as Fe > Zn > Mn > Cr > Cu > Ni > Cd > Pb. The Kruskal-Wallis ANOVA tests displayed a highly significant (p < 0.05) difference among the sampling locations. However, the concentration of PTE was below permissible limits, indicating no potential hazard in consuming the A. bisporus. Similarly, the health risk assessment studies using the target hazard quotient (THQ) also showed no significant health risk associated with the consumption of A. bisporus being sold in the local mushroom markets of Uttarakhand, India. This study is the first report on state-level monitoring of PTE in A. bisporus mushrooms, which provides crucial information regarding the monitoring and occurrence of potentially toxic metallic elements. | Kumar, Pankaj; Kumar, Vinod; Eid, Ebrahem M.; AL-Huqail, Arwa A.; Adelodun, Bashir; Abou Fayssal, Sami; Goala, Madhumita; Arya, Ashish Kumar; Bachheti, Archana; Andabaka, Zeljko; Choi, Kyung Sook; Siric, Ivan | Gurukula Kangri Deemed Univ, Dept Zool & Environm Sci, Agroecol & Pollut Res Lab, Haridwar 249404, Uttarakhand, India; King Khalid Univ, Coll Sci, Biol Dept, Abha 61321, Saudi Arabia; Kafrelsheikh Univ, Fac Sci, Bot Dept, Kafr Al Sheikh 33516, Egypt; Princess Nourah Bint Abdulrahman Univ, Coll Sci, Dept Biol, POB 84428, Riyadh 11671, Saudi Arabia; Univ Ilorin, Dept Agr & Biosyst Engn, PMB 1515, Ilorin 240103, Nigeria; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea; Univ Forestry, Fac Agron, Dept Agron, 10 Kliment Ohridski Blvd, Sofia 1797, Bulgaria; Lebanese Univ, Fac Agr, Dept Plant Prod, Beirut 1302, Lebanon; Affiliated Assam Univ, Nehru Coll, Silchar 788098, Assam, India; Graph Era Deemed Univ, Dept Environm Sci, Dehra Dun 248002, Uttarakhand, India; Univ Zagreb, Fac Agr, Svetosimunska 25, Zagreb 10000, Croatia | Eid, Ebrahem/O-2723-2013; Adelodun, Bashir/O-2941-2018; AL-Huqail, Arwa/AAZ-3925-2020; bachheti, Archana/N-5749-2017; Abou Fayssal, Sami/ABF-6226-2020; Kumar, P.Vinod/HKP-1552-2023; AL-Huqail, Arwa A./AAZ-3925-2020; Kumar, Dr. Vinod/K-9971-2016; Kumar, Pankaj/AAF-2231-2019; Arya, Ashish Kumar/AAO-8554-2021 | 57281192700; 57200152850; 35794350700; 57192198035; 57193774482; 57218598581; 57221943148; 57225657736; 55437052500; 55934838700; 54392662900; 55233815400 | rs.pankajkumar@gkv.ac.in;drvksorwal@gkv.ac.in;ebrahem.eid@sci.kfs.edu.eg;aaalhuqail@pnu.edu.sa;adelodun.b@unilorin.edu.ng;sami.aboufaycal@st.ul.edu.lb;madhumitagoalap@gmail.com;ashishkumararya_20941076.evs@geu.ac.in;bachheti.archana@gmail.com;zandabaka@agr.hr;ks.choi@knu.ac.kr;isiric@agr.hr; | JOURNAL OF FUNGI | J FUNGI | 2309-608X | 8 | 5 | SCIE | MICROBIOLOGY;MYCOLOGY | 2022 | 4.7 | 28.3 | 2.93 | 2025-06-25 | 25 | 25 | cluster analysis; health risk; potentially toxic elements; mushroom; spatial analysis; principal component | PRINCIPAL COMPONENT ANALYSIS; HEAVY-METALS; HEALTH-RISK; BIOACCUMULATION; SOILS; CONTAMINATION | cluster analysis; health risk; mushroom; potentially toxic elements; principal component; spatial analysis | English | 2022 | 2022-05 | 10.3390/jof8050452 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

Laboratory experiments were performed under controlled environmental conditions to grow A. bisporus on the composted wheat straw substrate for 50 days. Different treatments (0, 50, 100, 150, and 200 g/kg) of casing material were prepared by mixing garden and dried SS and applied on the mushroom substrate after proper sterilization. The results revealed that SS application was significant (p 0.9900), high model efficiency (ME > 0.98), and low root mean square error (RMSE < 0.410) values, respectively. The findings of this study represent sustainable use of SS for the formulation of mushroom casing material contributing toward synergistic agro-economy generation and waste management. | Kumar, Pankaj; Kumar, Vinod; Adelodun, Bashir; Bedekovic, Dalibor; Kos, Ivica; Siric, Ivan; Alamri, Saad A.

| ○ | ○ | Article | Unraveling the Genome Sequence of Plant Growth Promoting Aspergillus niger (CSR3) Provides Insight into the Synthesis of Secondary Metabolites and Its Comparative Genomics | Aspergillus niger strain CSR3 is an endophytic fungus that regulates plant endogenous hormones, secondary metabolites, and promotes plant growth during abiotic stress conditions. In this study, we sequenced the genome of A. niger (CSR3) and compared it with previously available A. niger strains. The final genome assembly was 35.8 Mb in size, consisting of 23 scaffolds with N50 scaffold length of 2.4 Mb. A total of 12,442 protein coding genes, 270 tRNA, and 57 rRNA were predicted in the CSR3 genome. We used comparative genomic analysis to provide insights into the genome's evolution and to elucidate the adaptive genomic signatures for bioactive secondary metabolite biosynthesis, hormones biosynthesis, and plant growth promoting activities. We also analyzed the transposable elements (TEs), simple sequence repeats (SSRs), CAZymes families, genes involved in gibberellin biosynthesis, and secondary metabolite clusters in the CSR3 genome. A total of 21 secondary metabolite biosynthesis gene clusters were detected, with 18 essential enzymes involved in the mevalonate pathway (MVA). The repeat analysis revealed about 3431 SSR, 274 TEs, and 205 inverted repeats (IR). Further gene family analysis revealed that 124 gene families were gained, whereas 125 gene families were lost in CSR3 genome, compared to A. niger ASM151534V and A. niger ASM285V2 genomes. The results improve our understanding of the CSR3 genome and will assist in future investigations on the genetic basis of A. niger CSR3, including the identification of CSR3 phytostimulant properties. | Lubna; Asaf, Sajjad; Jan, Rahmatullah; Khan, Abdul Latif; Bilal, Saqib; Asif, Saleem; Al-Harrasi, Ahmed; Kim, Kyung-Min | Abdul Wali Khan Univ, Dept Bot, Garden Campus, Mardan 23200, Pakistan; Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 616, Oman; Kyungpook Natl Univ, Coll Agr & Life Sci, Sch Appl Biosci, Div Plant Biosci, 80 Dahak Ro, Daegu 41566, South Korea; Univ Houston, Coll Technol, Dept Engn Technol, Sugar Land, TX 77479 USA | Asaf, Sajjad/ABA-3647-2021; Kim, Kyung-Min Kim/C-7007-2014; Ul-Hamid, Anwar/B-7297-2015; Khan, Abdul/H-5910-2011; Jan, Rahmatullah/AIC-3439-2022 | 57200621537; 56595059900; 57201981969; 26639372800; 57031617400; 57396413700; 6506093146; 34868260300 | lubnabilal68@gmail.com;sajadasif2000@gmail.com;rehmatbot@yahoo.com;latifepm78@yahoo.co.uk;saqib@unizwa.edu.om;saleemasif10@gmail.com;aharrasi@unizwa.edu.om;kkim@knu.ac.kr; | JOURNAL OF FUNGI | J FUNGI | 2309-608X | 8 | 2 | SCIE | MICROBIOLOGY;MYCOLOGY | 2022 | 4.7 | 28.3 | 0.94 | 2025-06-25 | 6 | 8 | fungi; Aspergillus niger; genome sequencing; plant growth promoting; transposable element; CAZymes; orthogroup | GIBBERELLIN BIOSYNTHESIS; TRANSPOSABLE ELEMENTS; ENDOPHYTES; ANNOTATION; DIVERSITY; EVOLUTION; FAMILY; FUNGI; GENE; INTERPROSCAN | Aspergillus niger; CAZymes; Fungi; Genome sequencing; Orthogroup; Plant growth promoting; Transposable element | English | 2022 | 2022-02 | 10.3390/jof8020107 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Workplace spirituality and innovative work behavior: the role of employee flourishing and workplace satisfaction | Purpose The purpose of this study is to explore the role of employee flourishing as a mechanism to explain the relationship between workplace spirituality and employees' innovative work behavior (IWB). Furthermore, this study investigates how the relationship between workplace spirituality and innovative behavior is moderated by employees' perceived workplace satisfaction. Design/methodology/approach Based on structural equation modeling and hierarchical regression analysis, we conducted a cross-sectional survey of 236 millennial workers in China's service and manufacturing industries. Findings The research findings confirmed that workplace spirituality positively predicted the innovative behavior of employees; furthermore, employee flourishing and workplace satisfaction mediated and moderated the relationship between workplace spirituality and employee innovation, respectively. Practical implications This study's findings suggest that workplace spirituality unlocks employees' innovative behavior through a heightened sense of flourishing and enhanced sense of workplace satisfaction. Organizations are advised to foster a climate conducive of workplace spirituality by developing mutually aligned values. Moreover, organizations are advised to train leaders on workplace spirituality dimensions and foster workplace practices that facilitate self-reflection, job crafting and team building, as a means of broadening employees' emotional states and workplace satisfaction. Originality/value Few studies have examined the mechanisms that shape employees' innovative behavior through workplace spirituality. This study fills several research gaps by extending the theoretical implications of workplace spirituality and employee flourishing, as demonstrated by the multi-faceted role these variables play in motivating employees' innovative behavior among Chinese millennials. Additionally, this study demonstrates that higher levels of workplace satisfaction contribute to higher levels of innovative behavior. | Hunsaker, William D.; Ding, Wenjing | Kyungpook Natl Univ, Coll Business, Daegu, South Korea; Kyungpook Natl Univ, Daegu, South Korea | Ding, Wenjing/LLK-0950-2024; Hunsaker, William/E-9696-2017 | 55974245100; 57666879000 | hunsaker@knu.ac.kr; | EMPLOYEE RELATIONS | EMPL RELAT | 0142-5455 | 1758-7069 | 44 | 6 | SSCI | INDUSTRIAL RELATIONS & LABOR;MANAGEMENT | 2022 | 3.4 | 28.3 | 3.03 | 2025-06-25 | 27 | 28 | Innovative work behaviour; Workplace spirituality; Employee well-being; Workplace satisfaction; Employee flourishing | JOB DEMANDS; RESOURCES; CREATIVITY; LEADERSHIP; OUTCOMES; MODEL; ORGANIZATIONS; ENGAGEMENT; SCIENCE; CULTURE | Employee flourishing; Employee well-being; Innovative work behaviour; Workplace satisfaction; Workplace spirituality | English | 2022 | 2022-09-23 | 10.1108/er-01-2021-0032 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Cross-Linked Polyimide/ZIF-8 Mixed-Matrix Membranes by In Situ Formation of ZIF-8: Effect of Cross-Linking on Their Propylene/Propane Separation | Despite their potential for the scalable production of mixed-matrix membranes (MMMs), the MMMs prepared by the polymer-modification-enabled in situ metal-organic framework formation (PMMOF) process showed a considerable reduction in gas permeability as the filler loading increased. It was hypothesized that a correlation existed between the decrease in permeability and the change in the properties of the polymer, such as free volume and chain flexibility, upon in situ MOF formation. Herein, we aim to address the permeability reduction by using a cross-linked polyimide (6FDA-DAM:DABA (3:2)). It was found the degree of cross-linking affected not only the properties of the polymer, but also the in situ formation of the ZIF-8 filler particles in the cross-linked polymer. The proper degree of cross-linking resulted in suppressing C3H6 permeability reduction, suggesting a possible strategy to overcome the issue of PMMOF. The swelling of the polymer followed by chain rearrangement during the PMMOF, as well as the structural rigidity of the polymer, were found to be critical in mitigating permeability reduction. | Park, Sunghwan; Jeong, Hae-Kwon | Kyungpook Natl Univ, Sch Energy Mat & Chem Engn, Sangju Si 37224, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju Si 37224, South Korea; Texas A&M Univ, Artie McFerrin Dept Chem Engn, College Stn, TX 77843 USA; Texas A&M Univ, Dept Mat Sci & Engn, College Stn, TX 77843 USA | Park, Sunghwan/AAB-7509-2020 | 56402062100; 7401619878 | sunghwan@knu.ac.kr;hjeong7@tamu.edu; | MEMBRANES | MEMBRANES-BASEL | 2077-0375 | 12 | 10 | SCIE | CHEMISTRY, PHYSICAL;ENGINEERING, CHEMICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;POLYMER SCIENCE | 2022 | 4.2 | 28.5 | 0.46 | 2025-06-25 | 6 | 7 | mixed-matrix membrane; zeolitic imidazolate framework; polymer cross-linking; in situ growth; propylene; propane separation | NATURAL-GAS PURIFICATION; PLASTICIZATION RESISTANCE; POLYMERS; OPPORTUNITIES; PERFORMANCE; PROPANE | in situ growth; mixed-matrix membrane; polymer cross-linking; propylene/propane separation; zeolitic imidazolate framework | Crosslinking; Filled polymers; Fillers; Gas permeable membranes; Polyimides; Propylene; Cross-linked polyimides; In-situ formations; In-situ growth; Metalorganic frameworks (MOFs); Mixed-matrix membranes; Permeability reduction; Polymer cross-linking; Polymer modifications; Propylene/propane separation; Zeolitic imidazolate frameworks; Gas permeability | English | 2022 | 2022-10 | 10.3390/membranes12100964 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Desalination Technology in South Korea: A Comprehensive Review of Technology Trends and Future Outlook | Due to advances in desalination technology, desalination has been considered as a practical method to meet the increasing global fresh water demand. This paper explores the status of the desalination industry and research work in South Korea. Desalination plant designs, statistics, and the roadmap for desalination research were analyzed. To reduce energy consumption in desalination, seawater reverse osmosis (SWRO) has been intensively investigated. Recently, alternative desalination technologies, including forward osmosis, pressure-retarded osmosis, membrane distillation, capacitive deionization, renewable-energy-powered desalination, and desalination batteries have also been actively studied. Related major consortium-based desalination research projects and their pilot plants suggest insights into lowering the energy consumption of desalination and mitigation of the environmental impact of SWRO brine as well. Finally, considerations concerning further development are suggested based on the current status of desalination technology in South Korea. | Park, Jongkwan; Lee, Sungyun | Changwon Natl Univ, Sch Civil Environm & Chem Engn, 20 Changwondaehak Ro, Changwon Si 51140, South Korea; Kyungpook Natl Univ, Sch Disaster Prevent & Environm Engn, Dept Civil Environm Engn, 2559 Gyeongsang Daero, Sangju Si 37224, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, 2559 Gyeongsang Daero, Sangju Si 37224, South Korea | 56969869700; 36438267000 | jkpark2019@changwon.ac.kr;sungyunlee@knu.ac.kr; | MEMBRANES | MEMBRANES-BASEL | 2077-0375 | 12 | 2 | SCIE | CHEMISTRY, PHYSICAL;ENGINEERING, CHEMICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;POLYMER SCIENCE | 2022 | 4.2 | 28.5 | 0.85 | 2025-06-25 | 22 | 27 | seawater desalination; reverse osmosis; industry; research; alternative technology; energy; South Korea | REVERSE-OSMOSIS DESALINATION; 2ND PASS; HYBRID; ENERGY; SWRO; PERFORMANCE; SALINITY; DRIVERS; BATTERY; SYSTEM | Alternative technology; Energy; Industry; Research; Reverse osmosis; Seawater desalination; South Korea | Distillation; Energy utilization; Environmental impact; Pilot plants; Reverse osmosis; Seawater; Alternative technologies; Desalination technologies; Energy; Fresh Water; Practical method; Review of technologies; Sea water; Seawater desalination; South Korea; Technology trends; Desalination | English | 2022 | 2022-02 | 10.3390/membranes12020204 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Evaluation of Slag Entrainment by Large Argon Bubble Rupturing Using Dynamic Similarity Modeling in Continuous Casting Mold | Slag entrainments in a continuous casting mold are caused by several factors and can generate severe steel product defects. Specifically, the argon bubbles injected from a submerged entry nozzle (SEN) to prevent molten steel solidification at the inner surface of the SEN can cause slag entrainments by altering the meniscus flow pattern and bursting on the slag layer. Most previous studies have focused on the variation in meniscus flows under argon gas injection, considering the argon bubbles as virtual volume particles. However, the effect of argon bubble rupture has not been investigated systematically, although the rupture of argon bubbles larger than 5 mm can directly entrain the slag into the molten steel. Therefore, in this study, we numerically investigated the dynamics in a large argon bubble (LAB) rising through a molten steel and bursting near the slag layer. This study is the first attempt to numerically investigate the effect of LAB rupture on slag entrainment using multiphase simulations based on dynamic similarity modeling. It was found that the strong wake flow behind the rising LAB can cause slag entrainment, and that it is influenced by the bubble Reynolds number, Bond number, and slag layer thickness. Further, slag entrainment occurrence maps were plotted, and the critical LAB sizes for 5 and 10 mm slag layers were revealed to be approximately 10 and 11 mm. | Lee, Jong Hui; Han, Sang-Woo; Cho, Hyun-Jin; Park, Il Seouk | Kyungpook Natl Univ, Dept Mech Engn, 80 Daehakro, Daegu 41566, South Korea; POSCO, Steelmaking Res Grp, Tech Res Labs Pohang Res Lab, 6261 Donghaeanro, Pohang 37859, Gyeongbuk, South Korea; Kyungpook Natl Univ, Sch Mech Engn, 80 Daehakro, Daegu 41566, South Korea | Lee, Jong Hui/JFT-0292-2023 | 57204669495; 55356225500; 57203005367; 50262800000 | einstein@knu.ac.kr; | METALLURGICAL AND MATERIALS TRANSACTIONS B-PROCESS METALLURGY AND MATERIALS PROCESSING SCIENCE | METALL MATER TRANS B | 1073-5615 | 1543-1916 | 53 | 6 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2022 | 3 | 28.5 | 0.09 | 2025-06-25 | 2 | 2 | NUMERICAL-SIMULATION; WATER MODEL; FLOW; STEEL; MAGNETOHYDRODYNAMICS; TRANSPORT; POWDER; GAS | Argon; Continuous casting; Flow patterns; Laboratories; Molds; Reynolds number; Steel foundry practice; Argon bubble; Bubble rupture; Continuous casting mould; Dynamic similarities; Molten steel; Product defects; Similarity models; Slag entrainment; Steel products; Submerged entry nozzles; Slags | English | 2022 | 2022-12 | 10.1007/s11663-022-02628-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

However, there has been a continuous demand for membranes with QQ capability. Thus, herein, we report a novel double-layered membrane comprising an outer layer containing a QQ bacterium (BH4 strain) on the polysulfone hollow fiber membrane. The double-layered composite membrane significantly inhibits biofilm formation (i.e., the biofilm density decreases by similar to 58%), biopolymer accumulation (e.g., polysaccharide), and signal molecule concentration (which decreases by similar to 38%) on the membrane surface. The transmembrane pressure buildup to 50 kPa of the BH4-embedded membrane (17.8 h +/- 1.1) is delayed by more than thrice (p < 0.05) of the control with no BH4 in the membrane's outer layer (5.5 h +/- 0.8). This finding provides new insight into fabricating antibiofouling membranes with a self-regulating property against biofilm growth. | Lee, Kibaek; Shah, Syed Salman Ali; Park, Hyeona; Lee, Chung-Hak; Choo, Kwang-Ho | Chonnam Natl Univ, Dept Biotechnol & Bioengn, Gwangju 61186, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Inst Water Ind, Daegu 41566, South Korea; Seoul Natl Univ, Sch Chem & Biol Engn, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Choo, Kwang-Ho/A-3456-2016; 이, 정학/GWQ-6252-2022; Shah, Syed Salman Ali/JCE-1663-2023 | 55845961700; 57215722996; 57213039681; 7410142508; 7102083272 | kibaek@jnu.ac.kr;salmankakakhel@yahoo.com;gusdk07727@naver.com;leech@snu.ac.kr;chookh@knu.ac.kr; | MEMBRANES | MEMBRANES-BASEL | 2077-0375 | 12 | 3 | SCIE | CHEMISTRY, PHYSICAL;ENGINEERING, CHEMICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;POLYMER SCIENCE | 2022 | 4.2 | 28.5 | 0.77 | 2025-06-25 | 8 | 10 | biofouling; layered membrane; membrane bioreactor; QQ membrane; quorum quenching; quorum sensing | BIOFOULING CONTROL; ENERGY-CONSUMPTION; BIOREACTOR MBR; PARADIGM | Biofouling; Layered membrane; Membrane bioreactor; QQ membrane; Quorum quench-ing; Quorum sensing | Biofilms; Biofouling; Biopolymers; Composite membranes; Cylinders (shapes); Quenching; Antibiofouling; Continuous demand; Hollow cylinders; Layered membranes; Outer layer; Quenching media; Quorum quench-ing; Quorum quenching; Quorum quenching membrane; Quorum-sensing; Bioreactors | English | 2022 | 2022-03 | 10.3390/membranes12030296 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
