| ○ | ○ | Article | Heart failure and atrial fibrillation: tachycardia-mediated acute decompensation | Aims Tachycardia is a reversible event that may cause hemodynamic decompensation but may not necessarily cause direct damages to the myocardium. To evaluate the clinical outcomes of patients with heart failure (HF) and atrial fibrillation (AF), whose acute decompensation was tachycardia mediated. Methods and results The Korean Acute Heart Failure registry was a prospective registry that consecutively enrolled 5625 patients with acute HF. Patients were classified into three groups according to the rhythm and aggravating factor: (i) 3664 (65.1%) patients with sinus rhythm (SR), (ii) 1033 (18.4%) patients with AF whose decompensation was tachycardia-mediated, AF-TM (+), and (iii) N = 928 (16.5%) patients with AF whose decompensation was not tachycardia-mediated, AF-TM (-). The primary outcomes were in-hospital and post-discharge 1 year all-cause mortality. At admission, the mean heart rate was 90.8 +/- 23.4, 86.8 +/- 26.8, and 106.3 +/- 29.7 beats per minute for the SR, AF-TM (-), and AF-TM (+) groups, respectively. The AF-TM (+) group had more favourable characteristics such as de novo onset HF, less diabetes, ischaemic heart disease, and higher blood pressure than the AF-TM (-) group. In-hospital mortality rates were 5.1%, 6.5%, and 1.7% for SR, AF-TM (-), and AF-TM (+) groups, respectively. In logistic regression analysis, the AF-TM (+) group had lower in-hospital mortality after adjusting the significant covariates (odds ratio, 0.49; 95% confidence interval, 0.26-0.93). The mortality rate did not differ between SR and AF-TM (-) groups. During 1 year follow-up, 990 (18.5%) patients died. In univariate and multivariate Cox proportional regression analyses, there was no difference in 1-year all-cause mortality between the three groups. Conclusions In patients with HF and AF, patients whose acute decompensation is tachycardia-mediated have better in-hospital, but similar post-discharge outcomes compared with those with SR or those with AF whose decompensation is not tachycardia-mediated.

| ○ | ○ | Article | Mobility and source apportionment of As and heavy metals in the Taehwa River sediment, South Korea: anthropogenic and seasonal effects | The river sediment is a sink for heavy metals flowed into a river from natural and anthropogenic sources. It can be a potential pollutant source in varying environmental conditions. The Taehwa River runs through Ulsan City with different geological terrains and different land uses. Hence, research on the determination of various factors affecting accumulation and mobility changes in heavy metals in the river sediment is important. The present research investigated the mineralogical compositions of the Taewha River sediment in addition to the distribution, speciation, sources, and contamination level of As and heavy metals. The sediment showed different mineralogical changes associated with flowing distance, indicating the influence of country rocks, comprising igneous rocks in the upper stream region and sedimentary rocks in the lower stream region, on mineral composition. The total concentrations of As and heavy metals in the sediment exhibited the order of Zn>Pb>Cr>Cu>Ni>As>Cd. The overall concentrations of As and heavy metals increased in the downstream region, albeit with varying degrees. According to the Environmental Protection Agency guideline for sediment pollution, including the index of pollution intensity (I-POLL) and the potential ecological risk index (RI), the sediment in the sampling stations was discovered to be polluted to varying degrees from anthropogenic activities. An abrupt increase in Pb, Zn, and Cd concentrations was observed at Station 3 in summer and fall, which was linked to the increased clay mineral content caused by seasonal and lithological changes. The sources of this increase can be attributed to a nearby industrial complex or the oxidation of sulfide minerals, which could be related to an abandoned amethyst mine. Sequential extraction studies show that potential toxicity varies for each metal. By comparison, metals such as Cr, Ni, and Cu with higher percentages in exchangeable fractions and fractions bound to carbonates can be highly toxic. The statistical analysis indicates that two groups of metals, one including Zn, Cd, and Pb and another including Cr, Ni, As, and Cu, had distinct origins. | Shin, Ji-Hwan; Jo, Duk-Hee; Kim, Yeongkyoo | Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea | 57221742295; 57221747260; 7410207179 | ygkim@knu.ac.kr; | ENVIRONMENTAL EARTH SCIENCES | ENVIRON EARTH SCI | 1866-6280 | 1866-6299 | 80 | 3 | SCIE | ENVIRONMENTAL SCIENCES;GEOSCIENCES, MULTIDISCIPLINARY;WATER RESOURCES | 2021 | 3.119 | 47.5 | 0.3 | 2025-07-30 | 4 | 4 | River sediment; Heavy element; Sequential extraction; Index of pollution intensity (I-POLL); Ecological risk index (Er) | SEQUENTIAL EXTRACTION; SOURCE IDENTIFICATION; SURFICIAL SEDIMENTS; TRACE-METALS; GANGA RIVER; WATER; CONTAMINATION; POLLUTION; RISK; TRIBUTARIES | Ecological risk index (Er); Heavy element; Index of pollution intensity (I<sub>POLL</sub>); River sediment; Sequential extraction | South Korea; Ulsan [South Korea]; Abandoned mines; Copper; Environmental Protection Agency; Igneous rocks; Land use; Lead; Lithology; Minerals; Rivers; Sedimentary rocks; Sediments; Soil pollution; Sulfur compounds; Anthropogenic activity; Anthropogenic sources; Environmental conditions; Exchangeable fraction; Mineralogical changes; Mineralogical compositions; Oxidation of sulfides; Potential ecological risk; anthropogenic effect; arsenic; element mobility; fluvial deposit; heavy metal; pollutant source; seasonal variation; sediment pollution; source apportionment; River pollution | English | 2021 | 2021-01-19 | 10.1007/s12665-021-09371-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Generalizations of linear fractional maps for classical symmetric domains and related fixed point theorems for generalized balls | We extended the study of the linear fractional self maps (e.g., by Cowen-MacCluer and Bisi-Bracci on the unit balls) to a much more general class of domains, called generalized type I domains, which includes in particular the classical bounded symmetric domains of type I and the generalized balls. Since the linear fractional maps on the unit balls are simply the restrictions of the linear maps of the ambient projective space (in which the unit ball is embedded) on a Euclidean chart with inhomogeneous coordinates, and in this article we always worked with homogeneous coordinates, here the term linear map was used in this more general context. After establishing the fundamental result which essentially says that almost every linear self map of a generalized type I domain can be represented by a matrix satisfying the "expansion property" with respect to some indefinite Hermitian form, we gave a variety of results for the linear self maps on the generalized balls, such as the holomorphic extension across the boundary, the normal form and partial double transitivity on the boundary for automorphisms, the existence and the behavior of the fixed points, etc. Our results generalize a number of known statements for the unit balls, including, for example, a theorem of Bisi-Bracci saying that any linear fractional map of the unit ball with more than two boundary fixed points must have an interior fixed point. | Gao, Yun; Ng, Sui-Chung; Seo, Aeryeong | Shanghai Jiao Tong Univ, Sch Math Sci, Shanghai, Peoples R China; East China Normal Univ, Shanghai Key Lab PMMP, Sch Math Sci, Shanghai, Peoples R China; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | Seo, Aeryeong/GON-4707-2022 | 55503383100; 35264831700; 55266222700 | gaoyunmath@sjtu.edu.cn;scng@math.ecnu.edu.cn;aeryeong.seo@knu.ac.kr; | ANNALI DI MATEMATICA PURA ED APPLICATA | ANN MAT PUR APPL | 0373-3114 | 1618-1891 | 200 | 1 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.986 | 47.6 | 0 | 2025-07-30 | 0 | 0 | Generalized balls; Automorphisms; Linear fractional maps; Fixed points | COMPOSITION OPERATORS; RIGIDITY; MAPPINGS | Automorphisms; Fixed points; Generalized balls; Linear fractional maps | English | 2021 | 2021-02 | 10.1007/s10231-020-00984-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optimal inequalities for Riemannian maps and Riemannian submersions involving Casorati curvatures | Riemannian maps are generalizations of well-known notions of isometric immersions and Riemannian submersions. Most optimal inequalities on submanifolds in various ambient spaces are driven from isometric immersions. The main aim of this paper is to obtain optimal inequalities for Riemannian maps to space forms, as well as for Riemannian submersions from space forms, involving Casorati curvatures. | Lee, Chul Woo; Lee, Jae Won; Sahin, Bayram; Vilcu, Gabriel-Eduard | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Gyeongsang Natl Univ, Dept Math Educ, Jinju 52828, South Korea; Gyeongsang Natl Univ, RINS, Jinju 52828, South Korea; Ege Univ, Dept Math, Izmir, Turkey; Univ Bucharest, Res Ctr Geometry Topol & Algebra, Fac Math & Comp Sci, Str Acad 14,Sect 1, Bucharest 70109, Romania; Petr Gas Univ Ploiesti, Dept Cybernet Econ Informat Finance & Accountancy, Bd Bucuresti 39, Ploiesti 100680, Romania | ; Vilcu, Gabriel-Eduard/AAB-9005-2019; Sahin, Bayram/AAG-7872-2021 | 56100882300; 55917980500; 8411354100; 15081584300 | mathisu@knu.ac.kr;leejaew@gnu.ac.kr;bayram.sahin@ymail.com;gvilcu@upg-ploiesti.ro; | ANNALI DI MATEMATICA PURA ED APPLICATA | ANN MAT PUR APPL | 0373-3114 | 1618-1891 | 200 | 3 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.986 | 47.6 | 1.99 | 2025-07-30 | 22 | 20 | Riemannian map; Casorati curvature; delta-Casorati curvature; Normalized scalar curvature | LAGRANGIAN SUBMANIFOLDS; INVARIANT; SPACE | Casorati curvature; Normalized scalar curvature; Riemannian map; δ-Casorati curvature | English | 2021 | 2021-06 | 10.1007/s10231-020-01037-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Taylor spectrum approach to Brownian-type operators with quasinormal entry | In this paper, we introduce operators that are represented by upper triangular 2 x 2 block matrices whose entries satisfy some algebraic constraints. We call them Brownian-type operators of class Q, briefly operators of class Q. These operators emerged from the study of Brownian isometries performed by Agler and Stankus via detailed analysis of the time shift operator of the modified Brownian motion process. It turns out that the class Q is closely related to the Cauchy dual subnormality problem which asks whether the Cauchy dual of a completely hyperexpansive operator is subnormal. Since the class Q is closed under the operation of taking the Cauchy dual, the problem itself becomes a part of a more general question of investigating subnormality in this class. This issue, along with the analysis of nonstandard moment problems, covers a large part of the paper. Using the Taylor spectrum technique culminates in a full characterization of subnormal operators of class Q. As a consequence, we solve the Cauchy dual subnormality problem for expansive operators of class Q in the affirmative, showing that the original problem can surprisingly be extended to a class of operators that are far from being completely hyperexpansive. The Taylor spectrum approach turns out to be fruitful enough to allow us to characterize other classes of operators including m-isometries. We also study linear operator pencils associated with operators of class Q proving that the corresponding regions of subnormality are closed intervals with explicitly described endpoints. | Chavan, Sameer; Jablonski, Zenon Jan; Jung, Il Bong; Stochel, Jan | Indian Inst Technol Kanpur, Dept Math & Stat, Kanpur, Uttar Pradesh, India; Uniwersytet Jagiellonski, Inst Matematyki, Ul Lojasiewicza 6, PL-30348 Krakow, Poland; Kyungpook Natl Univ, Dept Math, Daegu 702701, South Korea | 56421613800; 6602624635; 7102964485; 6602273956 | chavan@iitk.ac.in;Zenon.Jablonski@im.uj.edu.pl;ibjung@knu.ac.kr;Jan.Stochel@im.uj.edu.pl; | ANNALI DI MATEMATICA PURA ED APPLICATA | ANN MAT PUR APPL | 0373-3114 | 1618-1891 | 200 | 3 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.986 | 47.6 | 1.05 | 2025-07-30 | 8 | 9 | Upper triangular 2 x 2 block matrix; Taylor's spectrum; Moment problems; Subnormal operator; m-isometry; Linear operator pencil | M-ISOMETRIC TRANSFORMATIONS; HYPERINVARIANT SUBSPACES; HILBERT-SPACE | Linear operator pencil; m-isometry; Moment problems; Subnormal operator; Taylor’s spectrum; Upper triangular 2 × 2 block matrix | English | 2021 | 2021-06 | 10.1007/s10231-020-01018-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Brassica oleracea var. capitata L. Alleviates Indomethacin-Induced Acute Gastric Injury by Enhancing Anti-Inflammatory and Antioxidant Activity | Brassica oleracea var. capitata L. (white cabbage) is a valuable vegetable with diverse nutraceutical benefit. Present study aimed to investigate the preventive effects of B. oleracea extract (BOE) standardized by vitamin U on indomethacin (IND)-induced acute gastric injury in Sprague-Dawley rats. Pre-administration of three different doses of BOE (12.5-50 mg/kg) for 14 days significantly decreased visible ulcerative lesions in the gastric tissue. In addition, BOE alleviated IND-mediated increase in histological score with inhibiting invaded percentage of lesion and restoring mucosa thickness in peri-ulcerative region. BOE increased the gastric tissue bound to Alcian blue and inhibited the decrease in hexose, sialic acid, and collagen levels by IND, suggesting that BOE protects the gastric tissue through preserving mucus and mucosal integrity. Moreover, BOE pre-administration blocked the reduction of prostaglandin E-2 and down-regulated histamine and mRNA expression related to secret gastric acid. Furthermore, BOE mitigated inflammatory responses in the gastric tissue by decreasing activity of myeloperoxidase and expression of nuclear factor-kappa B-dependent inflammatory genes. BOE also suppressed malondialdehyde with preventing the reduction of glutathione, superoxide dismutase, and catalase in the gastric tissue. Therefore, results from present study suggest that BOE will have a potential for preventing gastric injury. | Ryou, Seong Hwan; Cho, Il Je; Choi, Beom-Rak; Kim, Moon Bong; Kwon, Young Sam; Ku, Sae Kwang | Kyungpook Natl Univ, Coll Vet Med, Dept Vet Surg, Daegu 41566, South Korea; Daegu Haany Univ, Coll Korean Med, Dept Prekorean Med, Gyongsan 38610, South Korea; Cent Res Lab Nutracore Co Ltd, Suwon 16514, South Korea; Echo Trading Co, Res Lab, Seongnam 13596, South Korea | 57222197786; 36241202500; 56595969400; 57221269534; 7403459426; 7006331005 | rsh1613@knu.ac.kr;skek023@dhu.ac.kr;brchoi@nutracore.co.kr;mannatech@echot.co.kr;kwon@knu.ac.kr;gucci200@dhu.ac.kr; | PROCESSES | PROCESSES | 2227-9717 | 9 | 2 | SCIE | ENGINEERING, CHEMICAL | 2021 | 3.352 | 47.9 | 0.47 | 2025-07-30 | 7 | 9 | antioxidant; anti-inflammation; Brassica oleracea var; capitata L; extract (BOE); indomethacin (IND)-induced acute gastric injury | KAPPA-B; MUCOSAL DAMAGE; CABBAGE; ULCER; MECHANISMS; STOMACH; EXTRACT; LESIONS; ANTHOCYANINS; INFLAMMATION | Antioxidant; Anti‐inflammation; Brassica oleracea var. capitata L. extract (BOE); Indomethacin (IND)‐induced acute gastric injury | English | 2021 | 2021-02 | 10.3390/pr9020372 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Evaluation of Pb, Mg, Al, Zn, and Cu as Electrode Materials in the Electrocoagulation of Microalgae | Apart from the conventionally used iron (Fe) and aluminum (Al) electrodes in microalgae harvesting, experiments were designed to examine the viability of lead (Pb), magnesium (Mg), zinc (Zn), and copper (Cu) as electrode materials in the harvesting of microalgae. The effect of voltage on the flocculation efficiency (FE) of the electrode materials was examined and compared. By dividing the optimal FE values by their corresponding periods, a simple yet practical approach was used to rank the electrode materials. From highest to lowest flocculation efficiency, the results were as follows: Cu, Zn, Mg, Al, and Pb at 10 V; Mg, Zn, Cu, Al, and Pb at 20 V; and Mg, Zn, Al, Cu, and Pb at 30 V. Important factors such as temperature, periodic FE, consumption of electrode material, pH, and metallic concentrations in the effluent were evaluated. The temperature increase proposed to have been affected by electric resistance drop and anodic corrosion, between 1.7 & DEG;C and 3.3 & DEG;C, 5 & DEG;C and 8.9 & DEG;C, and 10.5 & DEG;C and 18.4 & DEG;C was recorded at 10 V, 20 V, and 30 V respectively. Except for the supernatants of the experiments from Al electrodes, which remained relatively unaffected by voltage and time, the pH of all the other supernatants increased with time and voltage. The effluents recorded metallic concentrations between 0.513 mg/L and 43.8 mg/L for Pb, 7.02 mg/L and 20.5 mg/L for Mg, 1.34 mg/L and 9.09 mg/L for Al, 0.079 mg/L and 0.089 mg/L for Zn, and 0.252 mg/L and 0.434 mg/L for Cu electrodes. | Phiri, Jesse T.; Pak, Hun; We, Junhyung; Oh, Sanghwa | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea | 57236845700; 57237676300; 57236565100; 26665620700 | jesset.phiri@knu.ac.kr;ph6524@knu.ac.kr;gud6417@knu.ac.kr;shoh@knu.ac.kr; | PROCESSES | PROCESSES | 2227-9717 | 9 | 10 | SCIE | ENGINEERING, CHEMICAL | 2021 | 3.352 | 47.9 | 0.67 | 2025-07-30 | 12 | 12 | electrocoagulation; microalgae; lead; magnesium; aluminum; zinc; copper | FLOCCULATION; NUCLEATION; FLOTATION; BIOMASS; GROWTH | Aluminum; Copper; Electrocoagulation; Lead; Magnesium; Microalgae; Zinc | English | 2021 | 2021-10 | 10.3390/pr9101769 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Identification of Plant Viruses Infecting Pear Using RNA Sequencing | Asian pear (Pyrus pyrifolia) is a widely cultivated and commercially important fruit crop, which is occasionally subject to severe economic losses due to latent viral infections. Thus, the aim of the present study was to examine and provide a comprehensive overview of virus populations infecting a major pear cultivar ('Singo') in Korea. From June 2017 to October 2019, leaf samples (n = 110) of pear trees from 35 orchards in five major pear-producing regions were collected and subjected to RNA sequencing. Most virus-associated contigs matched the sequences of known viruses, including apple stem grooving virus (ASGV) and apple stem pitting virus (ASPV). However, some contigs matched the sequences of apple green crinlde-associated virus and cucumber mosaic virus. In addition, three complete or nearly complete genomes were constructed based on transcriptome data and subjected to phylogenetic analyses. Based on the number of virus-associated reads, ASGV and ASPV were identified as the dominant viruses of 'Singo.' The present study describes the virome of a major pear cultivar in Korea, and looks into the diversity of viral communities in this cultivar. This study can provide valuable information on the complexity of genetic variability of viruses infecting pear trees. | Kim, Nam-Yeon; Lee, Hyo-Jeong; Kim, Hong-Sup; Lee, Su-Heon; Moon, Jae-Sun; Jeong, Rae-Dong | Chonnam Natl Univ, Inst Environmentally Friendly Agr, Dept Appl Biol, Gwangju 61185, South Korea; Seed Testing & Res Ctr, Korea Seed & Variety Serv, Gimcheon 39660, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 98411, South Korea; Korea Res Inst Biosci & Biotechnol, Plant Genome Res Ctr, Daejeon 34141, South Korea | Lee, Jae/AAD-3704-2019 | 57202820277; 57202973962; 59866421700; 57213176188; 56002012500; 25627606400 | jraed2@jnu.ac.kr; | PLANT PATHOLOGY JOURNAL | PLANT PATHOLOGY J | 1598-2254 | 2093-9280 | 37 | 3 | SCIE | PLANT SCIENCES | 2021 | 2.321 | 47.9 | 0.69 | 2025-07-30 | 5 | 9 | pear; plant viruses; RNA sequencing; viral population | RT-PCR DETECTION; 4 APPLE VIRUSES; GENETIC DIVERSITY; VIROMES | Pear; Plant viruses; RNA sequencing; Viral population | English | 2021 | 2021-06 | 10.5423/ppj.oa.01.2021.0009 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Improved Continuous-Cycling Method for PID Autotuning | An improved continuous-cycling method is proposed for the autotuning of the proportional-integral-derivative (PID) controller. The proposed method can identify the frequency response of the process at a preset phase angle without a modeling error. Moreover, it provides an exact frequency response even if a static disturbance is present. The proposed method is an improved version of the continuous-cycling method. The gain of the proportional controller in the continuous-cycling method is updated to obtain the continuous-cycling status automatically. To guarantee the preset phase angle of the frequency response, we place a phase shifter in the form of a time delay after the proportional controller. The results of simulation and experimental studies show that the proposed method can provide an exact frequency response even under static disturbance conditions and can be applied to real processes. | Kim, Kyeong Hoon; Bae, Jeong Eun; Chu, Syng Chul; Sung, Su Whan | Kyungpook Natl Univ, Dept Chem Engn, 1370 Sankyeok Dong, Daegu 702701, South Korea | 57195755639; 57218849373; 57218852891; 7202731867 | mg3soul@gmail.com;bje@knu.ac.kr;chu700@flash21.com;suwhansung@knu.ac.kr; | PROCESSES | PROCESSES | 2227-9717 | 9 | 3 | SCIE | ENGINEERING, CHEMICAL | 2021 | 3.352 | 47.9 | 0.4 | 2025-07-30 | 5 | 7 | autotuning; continuous-cycling; frequency response; phase angle; disturbance; harmonics | Autotuning; Continuous‐cycling; Disturbance; Frequency response; Harmonics; Phase angle | English | 2021 | 2021-03 | 10.3390/pr9030509 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Occurrence of Plant-Parasitic Nematodes of Turfgrass in Korea | Plant-parasitic nematodes are not only an important constraint on agricultural crop production, but also cause both direct and indirect damage to turfgrass, which is a ground cover plant. However, studies on plant-parasitic nematodes of turfgrass in Korea are scarce. A survey for plant-parasitic nematodes was carried out on 13 golf courses in Korea. The results yielded 28 species/taxa belonging to 16 genera and 12 families of plant-parasitic nematodes. Among the isolated species, Helicotylenchus microlobus, Mesocriconema nebraskense, Tylenchorhynchus claytoni, Mesocriconema sp., and Meloidogyne graminicola were the most prevalent species in all management zones. Twelve species were new records of plant-parasitic nematodes in Korea. Highest maximum densities were showed by T. claytoni, Paratylenchus nanus, M. nebraskense, M. graminicola, and H. microlobus.

| ○ | ○ | Article | Study on the Removal of Fluorescent Whitening Agent from Paper-Mill Wastewater Using the Submerged Membrane Bioreactor (SMBR) with Ozone Oxidation Process | In this study, paper-mill wastewater was treated using the Submerged Membrane Bioreactor (SMBR) process. In particular, the ozone oxidation treatment process is applied after SMBR to remove the fluorescent whitening agent, which is a trace pollutant and non-biodegradable. Fluorescent whitening agent concentration was indirectly measured by UV scanning and COD concentration. The concentration of COD before SMBR and ozone oxidation was 449.3 mg/L, and the concentration of treated water was 100.3 mg/l. The COD removal efficiency of paper-mill wastewater through SMBR and the ozone oxidation process was about 77.68%. The optimized amount of ozone was required for the removal of the fluorescent whitening agent after SMBR was 95 mg center dot O-3/l calculated by UV scan results. Additionally, the optimized amount of required ozone to remove COD was calculated to 0.126 mg center dot COD/mg center dot O-3. | Ryu, Seunghan; Lee, Sanghun; Oh, Hannah; Oh, Sanghwa; Park, Minsoo; Kim, Jinho; Heo, Jaeeun | Korea Dyeing & Finishing Technol Inst DYETEC, Daegu 41706, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41706, South Korea; Econity Co Ltd, Yongin 17162, South Korea; Ecoplus Co Ltd, Cheonan 31075, South Korea | ; Heo, Jaeeun/MFJ-9404-2025 | 57224995369; 57225000908; 57224469858; 26665620700; 57225000488; 57209158832; 57224998208 | rsh1007@dyetec.or.kr;lsh002@dyetec.or.kr;hannah5@dyetec.or.kr;shoh@knu.ac.kr;minsoo@econity.com;stevenk@econity.com;ejeheo@nature-plus.kr;kmuweb@gmail.com; | PROCESSES | PROCESSES | 2227-9717 | 9 | 6 | SCIE | ENGINEERING, CHEMICAL | 2021 | 3.352 | 47.9 | 0.07 | 2025-07-30 | 2 | 2 | membrane bioreactor (MBR); ozone oxidation; paper and paper-mill; fluorescent whitening agents; wastewater treatment | ACTIVATED-SLUDGE | Fluorescent whitening agents; Membrane bioreactor (MBR); Ozone oxidation; Paper and paper‐mill; Wastewater treatment | English | 2021 | 2021-06 | 10.3390/pr9061068 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Tomato Yellow Leaf Curl Virus Infection in a Monocotyledonous Weed (Eleusine indica) | Tomato yellow leaf curl virus (TYLCV) is one of the most important plant viruses belonging to the genus Begomovirus of the family Geminiviridae. To identify natural weed hosts that could act as reservoirs of TYLCV, 100 samples were collected at a TYLCV-affected tomato farm in Iksan from 2013 to 2014. The sample weeds were identified as belonging to 40 species from 18 families. TYLCV was detected in 57 samples belonging to 28 species through polymerase chain reaction using root samples including five species (Eleusine indica, Digitaria ciliaris, Echinochloa crus-galli, Panicum dichotomiflorum, and Setaria faberi) from the family Poaceae. Whitefly Bemisia tabaci-mediated TYLCV transmission from TYLCV-infected E. indica plants to healthy tomatoes was confirmed, and inoculated tomatoes showed typical symptoms, such as leaf curling and yellowing. In addition, TYLCV was detected in leaf and root samples of E. indica plants inoculated by both whitefly-mediated transmission using TYLCV-viruliferous whitefly and agro-inoculation using a TYLCV infectious clone. The majority of mastreviruses infect monocotyledonous plants, but there have also been reports of mastreviruses that can infect dicotyledonous plants, such as the chickpea chlorotic dwarf virus. No exception was reported among begomoviruses known as infecting dicots only. This is the first report of TYLCV as a member of the genus Begomovirus infecting monocotyledonous plants. | Kil, Eui-Joon; Byun, Hee-Seong; Hwang, Hyunsik; Lee, Kyeong-Yeoll; Choi, Hong-Soo; Kim, Chang-Seok; Lee, Sukchan | Andong Natl Univ, Dept Plant Med, Andong 36729, South Korea; Sungkyunkwan Univ, Coll Biotechnol & Bioengn, Suwon 16419, South Korea; Natl Acad Agr Sci, Crop Protect Div, Rural Dev Adm, Wonju 55365, South Korea; Anim & Plant Quarantine Agcy, Jungbu Reg Off, Incheon 22133, South Korea; Kyungpook Natl Univ, Div Appl Biosci, Coll Agr & Life Sci, Daegu 41566, South Korea; Natl Inst Crop Sci, Highland Agr Res Inst, Rural Dev Adm, Pyeongchang 25342, South Korea | Kil, Eui-Joon/AAZ-9823-2020; Kil, Eui-Joon/AFE-1359-2022 | 26534336800; 56191040100; 56417004300; 57217153096; 26538696700; 55598584400; 57213176749 | viruskil@anu.ac.kr;rdacskim@korea.kr;cell4u@skku.edu; | PLANT PATHOLOGY JOURNAL | PLANT PATHOLOGY J | 1598-2254 | 2093-9280 | 37 | 6 | SCIE | PLANT SCIENCES | 2021 | 2.321 | 47.9 | 0.49 | 2025-07-30 | 6 | 9 | Begomovirus; Bemisia tabaci; Geminiviridae; monocotyledonous plant; tomato yellow leaf curl virus | CHLOROTIC-DWARF-VIRUS; RESERVOIR; GEMINIVIRUS; EPIDEMICS; DISEASE; TYLCV; IDENTIFICATION; TRANSMISSION; SEQUENCE; CHICKPEA | Begomovirus; Bemisia tabaci; Geminiviridae; Monocotyledonous plant; Tomato yellow leaf curl virus | English | 2021 | 2021-12 | 10.5423/ppj.ft.11.2021.0162 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Changes in Clinical Characteristics among Febrile Patients Visiting the Emergency Department before and after the COVID-19 Outbreak | Purpose: Considering the risk of coronavirus disease (COVID-19) transmission through infected droplets, emergency department (ED) operations in response to febrile patients should be planned. We investigated the general and clinical characteristics of febrile patients visiting the ED and changes in admission rates via the ED during the COVID-19 outbreak. Materials and Methods: We performed a retrospective analysis of prospectively collected patients who visited 402 EDs in the Republic of Korea with febrile symptoms between January 27 and May 31, 2020 and compared them to those enrolled before the COVID-19 outbreak. The primary outcome was admission rate; the secondary outcome was length of stay (LOS) in the ED. Results: In total, 266519 patients had febrile symptoms at ED presentation after the COVID-19 outbreak. In 2019, before the outbreak, there were 437762 patients. The rate of ED visits among pediatric patients (aged <15 years) decreased to 21.4% after the COVID-19 outbreak, compared with 41.8% in 2019. The proportion of patients admitted after ED management was higher after the outbreak (31.3%) than before (25.2%). The adjusted odds ratio for admission was 1.04 (95% confidence interval: 1.02-1.05) after the outbreak. Compared to before the COVID-19 outbreak, the median ED LOS increased by 16 min after the outbreak. Conclusion: This study confirmed that admission rates and ED LOS increased for febrile patients visiting the ED after the COVID-19 outbreak. This could provide evidence for developing ED-related strategies in response to the ongoing COVID-19 outbreak and other infectious disease pandemics. | Lee, Seung Joon; Choi, Arom; Ryoo, Hyun Wook; Pak, Yun-Suk; Kim, Hyeon Chang; Kim, Ji Hoon | Natl Med Ctr, Natl Emergency Med Ctr, Seoul, South Korea; Yonsei Univ, Dept Emergency Med, Coll Med, 50-1 Yonsei Ro, Seoul 03722, South Korea; Yonsei Univ, Dept Prevent Med, Coll Med, 50-1 Yonsei Ro, Seoul 03722, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea | Kim, Hyeon/F-8796-2019; Kim, Jinwoo/NQF-6310-2025; Kim, Hyeon Chang/F-8796-2019 | 57214932566; 57203834959; 55350557500; 57223235896; 8540942600; 57194684393 | jichoon81@yuhs.ac.kr; | YONSEI MEDICAL JOURNAL | YONSEI MED J | 0513-5796 | 1976-2437 | 62 | 12 | SCIE | MEDICINE, GENERAL & INTERNAL | 2021 | 3.052 | 48.0 | 0.8 | 2025-07-30 | 7 | 7 | COVID-19; emergency service; fever | CORONAVIRUS DISEASE 2019 | COVID-19; Emergency service; Fever | adolescent; adult; aged; Article; coronavirus disease 2019; emergency ward; female; fever; health insurance; hospital admission; hospital discharge; human; hyperthermia; intensive care unit; Korea; length of stay; major clinical study; male; mortality; observational study; prospective study; respiratory tract infection; retrospective study | English | 2021 | 2021-12 | 10.3349/ymj.2021.62.12.1136 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Core-shell nickel-graphene nanoparticles for efficient tin sulfide/polymer bulk hetero-junction solar cells | The Nickel-Graphene core-shell nanoparticles (Ni-GR CSNPs) were synthesized by thermal chemical vapor deposition (T-CVD) method. The prepared materials were characterized by different physicochemical techniques. The sizes of the Ni-GR NPs are in the range of approximately 60-200 nm as measured from the outermost graphene layer. The Ni-GR CSNPs were incorporated to the device's photoactive layer, which supporting electron transfer faster by the charge selective graphene and the extraction of electrons prevented the recombination of holes and electrons. The surface roughness of photoactive layer was controlled by inserting a thin layer of ZnO with different thickness between the photoactive layer and the back contact. Finally, the device with the structure of glass/indium tin oxide (ITO)/(polyethylene dioxy thiophene doped with polystyrene-sulfonic acid (PEDOT:PSS)/SnS + PTB7 + Ni-GR CSNPs/zinc oxide (ZnO)/E-GaIn showed a power conversion efficiency (PCE) of similar to 3.2%. | Nguyen Tam Nguyen Truong; Nguyen Hoang Lam; Reddy, Vasudeva Reddy Minnam; Tamboli, Mohaseen S.; Kim, Chang Duk; Park, Chinho | Yeungnam Univ, Sch Chem Engn, 280 Daehak Ro, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Dept Phys, 80 Daehakro, Daegu 41566, South Korea; Korea Inst Energy Technol, 200 Hyeokshin Ro, Naju 58330, Jeollanam Do, South Korea | Lam, Nguyen/KRO-9111-2024 | 25958384000; 58313026700; 56524508600; 6506784566; 57200982445; 9334962600 | chpark@kentech.ac.kr; | JOURNAL OF MATERIALS SCIENCE-MATERIALS IN ELECTRONICS | J MATER SCI-MATER EL | 0957-4522 | 1573-482X | 32 | 19 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED;PHYSICS, CONDENSED MATTER | 2021 | 2.779 | 48.0 | 0.4 | 2025-07-30 | 5 | 5 | LAYER | Chemical vapor deposition; Conducting polymers; Conversion efficiency; Core shell nanoparticles; Electron transport properties; II-VI semiconductors; ITO glass; IV-VI semiconductors; Layered semiconductors; Nanoparticles; Oxide minerals; Shells (structures); Solar cells; Sulfur compounds; Surface roughness; Synthesis (chemical); Tin oxides; Zinc oxide; Charge selective; Different thickness; Electron transfer; Photoactive layers; Physicochemical techniques; Polystyrene sulfonic acid; Power conversion efficiencies; Thermal chemical vapor deposition; Graphene | English | 2021 | 2021-10 | 10.1007/s10854-021-06935-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Infliximab Therapy for Children with Moderate to Severe Ulcerative Colitis: A Step-Up versus a Top-Down Strategy | Purpose: We aimed to investigate clinical outcomes between top-down (TD) and conventional step-up (SU) therapies in pediatric patients with moderate to severe ulcerative colitis (UC). Materials and Methods: All patients underwent clinical and endoscopic evaluation at diagnosis and 4 months and 1 year after treatment. Patients who started treatment with corticosteroid were grouped in the SU group, while those that initiated early infliximab (IFX) were grouped in the TD group. Among the SU group, patients who eventually changed to IFX treatment due to steroid resistance or dependency were included in the SU(R) group. Results: In total, 44 children with moderate to severe UC were included for analysis. Twenty-one patients were included in the SU group, 23 were included in the TD group, and 10 were enrolled in the SU(R) group. Relapse rates were 47.6% (10/21) in the SU group and 17.4% (4/23) in the TD group (p=0.033). Among relapsed patients, the durations from remission to relapse were 17.3 months (0.9-46.9) in the SU group and 24.3 months (1.8-44.9) in the TD group. There was no statistically significant difference in the sustained durations of remission after IFX administration between the SU(R) and TD groups [3.9 (1.4-6.3) and 2.3 (0.3-5.2) years, respectively (p>0.05)]. Conclusion: According to our study, early use of IFX without corticosteroid treatment for children with moderate to severe UC helps to lower relapse rates. We also found that IFX was a very effective treatment for pediatric UC, with a sustained duration of remission similar between TD and SU(R) groups. | Kim, Mi Jin; Kim, Eunsil; Kang, Ben; Choe, Yon Ho | Sungkyunkwan Univ, Samsung Med Ctr, Dept Pediat, Sch Med, 81 Irwon Ro, Seoul 06351, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea | ; 康, 奔/JMQ-0812-2023; Kim, Mi Jin/GXH-9639-2022 | 56638815200; 57205500267; 57194823199; 21333712100 | i101016@skku.edu; | YONSEI MEDICAL JOURNAL | YONSEI MED J | 0513-5796 | 1976-2437 | 62 | 7 | SCIE | MEDICINE, GENERAL & INTERNAL | 2021 | 3.052 | 48.0 | 0.23 | 2025-07-30 | 4 | 5 | Ulcerative colitis; infliximab; children | INFLAMMATORY-BOWEL-DISEASE; MAINTENANCE THERAPY; PEDIATRIC-PATIENTS; ENDOSCOPIC INDEX; OPEN-LABEL; MANAGEMENT; AZATHIOPRINE; MULTICENTER; GUIDELINES; MECHANISMS | Childre; Infliximab; Ulcerative colitis | Adrenal Cortex Hormones; Child; Colitis, Ulcerative; Gastrointestinal Agents; Humans; Infliximab; Remission Induction; Retrospective Studies; Treatment Outcome; 6 methylthioinosine; azathioprine; C reactive protein; corticosteroid; infliximab; mesalazine; thiopurine methyltransferase; tioguanine; corticosteroid; gastrointestinal agent; infliximab; abdominal pain; adolescent; Article; blood cell count; body weight loss; clinical article; clinical assessment; clinical evaluation; clinical outcome; corticosteroid therapy; decision making; diarrhea; disease activity; drug dependence; drug therapy; endoscopy; erythrocyte sedimentation rate; female; gastrointestinal disease; genotype; hair loss; human; hypertransaminasemia; inflammatory bowel disease; laboratory test; leukocyte differential count; male; observational study; pancolitis; pediatric patient; pediatrics; physical examination; prospective study; rash; rectum hemorrhage; recurrence risk; relapse; remission; ulcerative colitis; child; retrospective study; treatment outcome | English | 2021 | 2021-07 | 10.3349/ymj.2021.62.7.608 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
