| ○ | ○ | Article | Multicenter Evaluation of the Implementation Status of Laboratory Tests in Korea and the Potential Usefulness of a Multiplex PCR Assay in Patients with Suspected Central Nervous System Infections | Background: The rapid diagnosis and treatment of central nervous system (CNS) infections are critical to minimizing morbidity and mortality. We evaluated the implementation status of laboratory tests in patients with suspected CNS infection, and the potential usefulness of a multiplex PCR assay for rapid and simultaneous detection in cerebrospinal fluid (CSF) of 14 targets capable of causing CNS infections. Methods: The study was conducted at 5 hospitals located in Daegu and Gyeongju over a period of 6 months. A total of 140 patients with suspected CNS infection were included. CSF samples were tested for 6 bacteria, 7 viruses, and 1 yeast using multiplex PCR (FilmArray Meningitis/Encephalitis Panel, BioFire Diagnostics/Biomerieux, Salt Lake City, UT, USA) and conventional diagnostic testing including chemistry tests, cell count, bacterial culture, antigen detection assay, and pathogen-specific PCR. Results: The five conventional tests most commonly performed were the chemistry and cell count (100%), bacterial culture (94.3%), enterovirus PCR (52.9%), and herpes simplex virus PCR (25.7%). Among the 140 CSF samples, 27 (19.3%) and 42 (30.0%) tested positive by conventional and the FilmArray ME panel testing, respectively. Conclusions: The detection rate of pathogens for CNS infections increased using only one FilmArray test compared to all of the conventional methods actually performed in patients with suspected CNS infection. | Roh, Soongki; Lee, Jong Ho; Ha, Gyoung Yim; Ham, Ji Yeon; Suh, Hunsuk; Ryoo, Namhee; Kim, Yu Kyung | Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea; Yeungnam Univ, Dept Lab Med, Coll Med, Daegu, South Korea; Dongguk Univ, Dept Lab Med, Gyeongju Hosp, Gyeongju, South Korea; Daegu Catholic Univ, Dept Lab Med, Univ Hosp, Daegu, South Korea; Keimyung Univ, Dept Lab Med, Sch Med, Daegu, South Korea | ; Kim, Young-Il/ISS-7678-2023 | 57209411088; 57193676397; 7004433720; 56464754800; 8709763700; 7801573357; 9237571900 | kimyg@knu.ac.kr; | CLINICAL LABORATORY | CLIN LAB | 1433-6510 | 66 | 1-2 | SCIE | MEDICAL LABORATORY TECHNOLOGY | 2020 | 1.138 | 84.5 | 0.08 | 2025-06-25 | 3 | 3 | multiplex PCR; meningitis; central nervous system infections; cerebrospinal fluid; FilmArray | MENINGITIS; BACTERIAL; PANEL | Central nervous system infections; Cerebrospinal fluid; FilmArray; Meningitis; Multiplex PCR | Adolescent; Adult; Bacteria; Central Nervous System Bacterial Infections; Central Nervous System Viral Diseases; Child; Child, Preschool; Female; Humans; Infant; Infant, Newborn; Male; Middle Aged; Molecular Diagnostic Techniques; Molecular Typing; Multiplex Polymerase Chain Reaction; Republic of Korea; Viruses; Young Adult; Acinetobacter baumannii; adolescent; adult; antigen detection; Article; bacterium culture; cell count; central nervous system infection; cerebrospinal fluid analysis; child; comparative study; Cytomegalovirus; Enterovirus; Epstein Barr virus; Escherichia coli; female; Haemophilus influenzae; Herpes simplex virus; hospital; human; Human herpesvirus 6; Klebsiella pneumoniae; Korea; laboratory test; Listeria monocytogenes; major clinical study; male; middle aged; multiplex polymerase chain reaction; Neisseria meningitidis; null result; statistically significant result; Stenotrophomonas maltophilia; Streptococcus agalactiae; Streptococcus pneumoniae; Varicella zoster virus; bacterium; central nervous system infection; genetics; infant; microbiology; molecular diagnosis; molecular typing; multiplex polymerase chain reaction; newborn; preschool child; procedures; South Korea; virology; virus; young adult | English | 2020 | 2020 | 10.7754/clin.lab.2019.190420 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Article | A Novel Paramagnetic Nanoparticle T2 Magnetic Resonance Imaging Contrast Agent With High Colloidal Stability: Polyacrylic Acid-Coated Ultrafine Dysprosium Oxide Nanoparticles | Until now, there have been limited studies on T2 magnetic resonance imaging (MRI) contrast agents (CAs) using paramagnetic nanoparticles (NPs). In this study, ultrafine dysprosium oxide (Dy2O3) NPs were synthesized as a T2 MRI CA. To obtain high biocompatibility and colloidal stability in aqueous medium for in vivo applications, they were grafted with polyacrylic acid. They displayed paramagnetism with an appreciable magnetization value at 300 K and consequently, an appreciable transverse water proton spin relaxivity (r2) value which increased as the applied MR field increased. Their potential as a T2 MRI CA was proved by taking in vivo T2 MR images in mice. © 2020 Korean Chemical Society, Seoul & Wiley-VCH GmbH | Marasini, Shanti; Yue, Huan; Ho, Son Long; Cha, Hyunsil; Park, Ji Ae; Jung, Ki-Hye; Ghazanfari, Adibehalsadat; Ahmad, Mohammad Yaseen; Liu, Shuwen; Chae, Kwon-Seok; Chang, Yongmin; Lee, Gang Ho | Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Molecular Medicine and Medical & Biological Engineering and DNN, School of Medicine, KNU and Hospital, Taegu, 41566, South Korea; Division of RI-Convergence Research, Korea Institute of Radiological & Medical Science (KIRAMS), Seoul, 01817, South Korea; Division of RI-Convergence Research, Korea Institute of Radiological & Medical Science (KIRAMS), Seoul, 01817, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea; Department of Biology Education and DNN, Teachers' College KNU, Taegu, 41566, South Korea; Department of Molecular Medicine and Medical & Biological Engineering and DNN, School of Medicine, KNU and Hospital, Taegu, 41566, South Korea; Department of Chemistry and Department of Nanoscience and Nanotechnology (DNN), College of Natural Sciences, Kyungpook National University (KNU), Taegu, 41566, South Korea | 57200329199; 57200329016; 55659242700; 57189728122; 16319690600; 53865234900; 57200327606; 57203054570; 57208926248; 15743626400; 7501840633; 7404851841 | ghlee@mail.knu.ac.kr;ychang@knu.ac.kr; | Bulletin of the Korean Chemical Society | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.38 | 2025-06-25 | 10 | High colloidal stability; Polyacrylic acid; T<sub>2</sub> magnetic resonance imaging; Ultrafine Dy<sub>2</sub>O<sub>3</sub> nanoparticle | Biocompatibility; Colloids; Dysprosium compounds; Mammals; Nanomagnetics; Nanoparticles; Organic acids; Paramagnetism; Aqueous medium; Colloidal Stability; Dysprosium oxide; Magnetic resonance imaging contrast agents; Magnetization values; Nanoparticle (NPs); Polyacrylic acids; Proton spins; Magnetic resonance imaging | English | Final | 2020 | 10.1002/bkcs.12074 | 바로가기 | 바로가기 | 바로가기 | |||||||
| ○ | ○ | Article | Binding Capability and Non-biofouling Efficacy of Poly[2-(methacryloyloxy)ethyl-4-pentynoate-co-oligo(ethylene Glycol) Methacrylate] Films on Gold Surfaces | We demonstrated the binding capability and non-biofouling efficacy of biotinylated, poly(MAEP-co-OEGMA) films using streptavidin and fibrinogen. The copolymeric films were synthesized on gold substrates without activation or passivation via the surface initiated-controlled radical polymerization of MAEP and OEGMA in five different molar ratios, followed by biotinylation using "click" chemistry. The copolymeric film synthesized with MAEP at a mole fraction of 0.2 exhibited the best performance of surface plasmon resonance. | Kim, Hyungwook; Hong, Seok-Pyo; Lee, Jungkyu K.; Lee, Bong Soo | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Korea Adv Inst Sci & Technol, Dept Chem, Ctr Cell Encapsulat Res, Daejeon 34141, South Korea; S&G Biotech Inc, Res Inst, Gyeonggi Do 17023, South Korea | Lee, BongSoo/AAP-3262-2020 | 57211604325; 55787346000; 8312040000; 59054459000 | jkl@knu.ac.kr;bslee@mail.sngbio.com; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.16 | 2025-06-25 | 3 | 3 | Surface functionalization; Polymeric coating; SI-ARGET ATRP; "Click" chemistry | SELF-ASSEMBLED MONOLAYERS; FUNCTIONALIZATION; IMMOBILIZATION; METHACRYLATE; ADSORPTION; PROTEINS; BRUSHES | Polymeric coating; SI-ARGET ATRP; Surface functionalization; “Click” chemistry | English | 2020 | 2020-02 | 10.1002/bkcs.11941 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Enantioseparation on AminoAlcohol-DerivedStationary Phases by Supercritical Fluid Chromatography and High-Performance Liquid Chromatograpy | Previous studies have shown that amino alcohol-derived chiral stationary phases can effectively separate some chiral samples. With the aim at improving the chiral separation, in this study, the composition and type of the mobile phase and the particle size of the stationary phase are changed, and the analytical method is carried out in parallel using high-performance liquid chromatograpy (HPLC) and supercritical fluid chromatography (SFC). By changing the type and composition of the mobile phase and reducing the particle size of the stationary phase, optimal separation and analysis conditions are obtained simultaneously for HPLC and SFC experiments. In particular, for a particle size of 3 mu m, the resolution increases for dinitrobenzoyl phenylglycinol and 2,2,2-trifluoro-1-(9-anthryl)ethanol. Moreover, replacing the organic modifier from methanol to isopropanol allows obtaining better results in the SFC experiments of dinitrobenzoyl phenylglycinol, dinitrobenzoyl leucinol, and 2,2,2-trifluoro-1-(9-anthryl)ethanol GTOC,Chiral separation by SFC and HPLC. | Kim, Gyuri; Ryoo, Jae Jeong | Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 702701, South Korea | 57219018514; 7004847725 | jjryoo@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.21 | 2025-06-25 | 4 | 4 | Chiral separation; Chiral stationary phase; HPLC; SFC | CHIRAL STATIONARY PHASES; BETA-CYCLODEXTRIN; SEPARATIONS; SFC | Chiral separation; Chiral stationary phase; HPLC; SFC | Amino alcohols; Chirality; Effluent treatment; Ethanol; Gas chromatography; Liquid chromatography; Particle size; Separation; Supercritical fluids; Analysis conditions; Analytical method; Chiral separations; Chiral stationary phasis; Enantioseparations; Resolution increase; Stationary phasis; Super critical fluid chromatography; Particle size analysis | English | 2020 | 2020-09 | 10.1002/bkcs.12094 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Enhanced Chemical Stability of D-Cycloserine via Tablet Form Containing Magnesium Oxide as an Alkali Stabilizer | The purpose of this study was to improve the chemical stability of D-cycloserine via tablet form containing an alkali stabilizer. The influence of alkalizing agents on the stability of D-cycloserine was investigated at 60 degrees C/75% RH for 2 days. The drug stability was evaluated with the D-cycloserine-loaded tablets prepared with various amounts of magnesium oxide using direct compression method. Compared to D-cycloserine powder and a commercial D-cycloserine-loaded product, the long-term drug stability on the chosen tablet was assessed at 40, 60, and 40 degrees C/75% RH during 6 months. Amongst the stabilizers investigated, magnesium oxide most improved the stability of D-cycloserine at the accelerated stress condition. The magnesium oxide/drug ratio of 1 and 2 showed higher remaining drug concentrations than those less than 0.5; however, two formers gave no significant difference in the remaining drug concentrations. Amongst the tablets tested, the formulation composed of D-cycloserine, magnesium oxide, and talc at the weight ratio of 250/250/5 most increased the stability of D-cycloserine. Additionally, due to the alkali and water-proofing property of magnesium oxide, this tablet improved the stability of D-cycloserine compared to the drug powder and commercial product. Hence, this novel tablet with enhanced drug stability would be a candidate for oral pharmaceutical product of D-cycloserine. | Kim, Jung Suk; Lee, Sang Min; Kim, Dong Shik; Kim, Dong Wuk; Kim, Kyeong Soo; Cho, Kwan Hyung; Li, Dong Xun; Jin, Sung Giu; Choi, Han-Gon | Hanyang Univ, Coll Pharm, Ansan 15588, South Korea; Hanyang Univ, Inst Pharmaceut Sci & Technol, Ansan 15588, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu, South Korea; Gyeongnam Natl Univ Sci & Technol, Dept Pharmaceut Engn, Jinju, South Korea; Inje Univ, Coll Pharm, Gimhae 621749, South Korea; Jiangxi Univ Tradit Chinese Med, Natl Pharmaceut Engn Ctr Solid Preparat Chinese H, Nanchang 330006, Jiangxi, Peoples R China; Dankook Univ, Dept Pharmaceut Engn, Cheonan 31116, South Korea | Kim, Kyeong Soo/AAJ-6800-2021; KIM, JUNG SUK/IAL-8910-2023 | 58290556000; 57212461521; 56320927900; 57193445049; 51763618300; 37030714200; 27168004100; 22979508200; 7404339910 | sklover777@dankook.ac.kr;hangon@hanyang.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.05 | 2025-06-25 | 1 | 1 | D-cycloserine; Tablet; Chemical stability; Magnesium oxide | IN-VIVO EVALUATION; LC-MS/MS METHOD; PHYSICOCHEMICAL CHARACTERIZATION; ORAL BIOAVAILABILITY; IMPROVED DISSOLUTION; HUMAN PLASMA; VALIDATION | Chemical stability; D-cycloserine; Magnesium oxide; Tablet | Magnesia; Magnesium powder; Accelerated stress; Commercial products; Cycloserine; Direct compression; Drug concentration; Drug stability; Pharmaceutical products; Tablet; Chemical stability | English | 2020 | 2020-01 | 10.1002/bkcs.11910 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Exfoliation of Na2Ti3O7 into Colloidal Nanosheets with Enhanced Discharge Capacity | Sodium-ion batteries (SIBs), which are being considered as possible alternatives to lithium-ion batteries, have attracted great scientific and industrial interest because sodium is inexpensive and more abundant than lithium. Among various anode materials for SIBs, Na2Ti3O7, with a layered structure, has a high potential due to its stable electrochemical sodiation/desodiation behavior. However, Na(2)Ti(3)O(7)has a large band-gap energy and a zigzag framework, which results in low electrical conductivity and poor sodium-ion diffusion. Thus, to circumvent such drawbacks, in this study, Na(2)Ti(3)O(7)was successfully exfoliated by the soft-chemical exfoliation technique via a two-step intercalation reaction. Transmission electron microscopy (TEM) studies show that the obtained exfoliated material is composed of thin nanosheets. Electrochemical sodium-ion storage tests showed that the exfoliated nanosheets had a much higher discharge capacity than bare bulk Na2Ti3O7, revealing that the exfoliation process could be utilized to develop new electrode materials with enhanced energy-storage properties. | Lee, Won-Jae; Lee, Minseop; Paek, Seung-Min | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | ; Paek, Seung-Min/E-4667-2011; Lee, Minseop/JVZ-7552-2024 | 57203094506; 57201550392; 7102686289 | smpaek@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.11 | 2025-06-25 | 4 | 5 | Intercalation; Exfoliation; Layered titanate; X-ray absorption spectroscopy; Sodium ion batteries | ANODE MATERIAL; ION | Exfoliation; Intercalation; Layered titanate; Sodium ion batteries; X-ray absorption spectroscopy | Anodes; Electric discharges; Energy gap; Energy storage; Exfoliation (materials science); High resolution transmission electron microscopy; Lithium-ion batteries; Metal ions; Nanosheets; Sodium compounds; Sodium-ion batteries; Discharge capacities; Electrical conductivity; Electrode material; Energy storage properties; Exfoliation process; High potential; Intercalation reaction; Layered Structures; Titanium compounds | English | 2020 | 2020-09 | 10.1002/bkcs.12086 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Molecular Level Investigation of Oil Sludge at the Bottom of Oil Tank in Ratawi Oil Field by Atmospheric Pressure Photo Ionization Ultrahigh-resolution Mass Spectrometry | The crude oil precipitate recovered from the bottom of oil tanks in the Ratawi oil field is analyzed by positive mode atmospheric pressure photoionization ultrahigh-resolution mass spectrometry (APPI UHR-MS). The precipitate is fractionated into three fractions and according to the APPI UHR-MS data, the mass spectrum of the top fraction is similar to that of the original oil while the middle fraction shows the lowest M-n and m/z distribution. The data obtained with APPI technique show that hydrocarbon molecules with aromatic rings and long alkyl chains are more abundant in the bottom fraction. In addition, vanadium is also found to be abundant in the bottom fraction. This study shows that aromatic compounds with long alkyl chains can be responsible for the solid deposits that are potentially harmful to oil processing equipment. Moreover, these results provide a basis for understanding the chemistry of the oil sludge formation. | Cho, Yunju; Abed, Hasanain Najm; Kim, Sunghwan | Kyungpook Natl Univ, Mass Spectrometry Convergence Res Inst, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Oil Pipelines Co, Res & Dev Dept, Baghdad 12009, Iraq | Kim, Sunghwan/HKN-9812-2023 | 36620209900; 57215202301; 57203772967 | sunghwank@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.38 | 2025-06-25 | 6 | 7 | Atmospheric Pressure Ionization; High-resolution Mass Spectrometry; Oil Precipitates | LASER-DESORPTION IONIZATION; CRUDE-OIL; ASPHALTENES; PRECIPITATION; SPECTRA | Atmospheric Pressure Ionization; High-resolution Mass Spectrometry; Oil Precipitates | Aromatic hydrocarbons; Atmospheric chemistry; Atmospheric ionization; Atmospheric pressure; Drug products; Hydrocarbon refining; Mass spectrometry; Molecules; Oil fields; Photoionization; Atmospheric pressure ionization; Atmospheric pressure photo ionization; High resolution mass spectrometry; Hydrocarbon molecules; Long alkyl chains; Middle fractions; Molecular levels; Ultrahigh resolution mass spectrometries; Oil tanks | English | 2020 | 2020-04 | 10.1002/bkcs.11991 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Study of the Dye Adsorption Kinetics ofMetal-OrganicFrameworks in Aqueous Media | Water can easily be contaminated by many dye molecules because of its high solubility with dense color. Dye-contaminated water requires purification via the adsorptive removal of dye molecules, employing various porous materials. To increase the removal efficiency and selectivity, demands for developing new metal-organic frameworks (MOFs) for dye removal continue to increase. Herein, we present a study on the dye-adsorption properties of MOFs based on their structures and pore sizes. The effects of dye molecule charge and size were also investigated. Three different MOFs (Universitetet i Oslo; UiO-66, UiO-67, Materials of Institute Lavoisier; MIL-100 [Fe]) and four dye molecules (Methylene Blue, Rhodamine B, Tropaeolin O, and Amaranth) were employed. The results suggest that the surface properties and framework structure of the MOFs affect dye adsorption capacity and kinetics, as characterized by UV-Vis spectroscopy and adsorption kinetics analysis. These results provide opportunities for the development of MOFs for dye removal from aqueous solution. | Kim, Sungjune; Lee, Jihyun; Son, Younghu; Yoon, Minyoung | Gachon Univ, Dept Nanochem, Seongnam 13120, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Son, Younghu/AAX-9531-2021 | 56946269900; 57211144130; 57216839175; 25222186500 | myyoon@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 1.77 | 2025-06-25 | 45 | 46 | Metal-organic framework; Dye removal; Adsorption kinetics | METAL-ORGANIC FRAMEWORK; CATIONIC DYES; FACILE SYNTHESIS; REMOVAL; EQUILIBRIUM | Adsorption kinetics; Dye removal; Metal–organic framework | Aromatic compounds; Driers (materials); Kinetics; Molecules; Pore size; Porous materials; Rhodamine B; Water pollution; Adsorption kinetics; Adsorptive removal; Dye removal from aqueous solutions; Dye-contaminated waters; Framework structures; High solubility; Removal efficiencies; VIS spectroscopy; Adsorption | English | 2020 | 2020-08 | 10.1002/bkcs.12076 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Synthesis and Application of New Calix[4]Arenes-Containing (R)-Phenylglycinol Chiral Stationary Phases for Enantioseparation | N-3,5-Dinitrobenzoyl-(R)-phenylglycinol silylation product was used as a high-performance liquid chromatography chiral stationary phase (CSP 1) for the resolution of various racemic samples, and some racemic samples were successfully separated. In this study, instead of the commonly used pi-acidic acyl chloride, calix[4]arenes were introduced to prepare two phenylglycinol CSPs (CSP 2, CSP 3). CSP 3 showed similar separation patterns as CSP 1 but different characteristics in specific samples. The newly prepared CSP 3 separated 10 of 13 pi-acidic, pi-basic, and oxazolidinone chiral samples and was especially useful for separating chiral oxazolidinones. In comparison between CSP 2 and CSP 3, CSP 2 separated fewer chiral samples than CSP 3 because of poor cavity and steric interactions. The newly developed C-methylcalix[4]resorcinarene derived CSP (CSP 3) will be a good model for the development of new stationary phase of this calixarene series. | Heo, Kyu Sung; Ryoo, Jae Jeong | Kyungpook Natl Univ, Dept Chem, Daegu 702701, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 702701, South Korea | 7004359251; 7004847725 | jjryoo@knu.ac.kr; | BULLETIN OF THE KOREAN CHEMICAL SOCIETY | B KOREAN CHEM SOC | 0253-2964 | 1229-5949 | 41 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 0.969 | 84.6 | 0.21 | 2025-06-25 | 7 | 6 | (R)-phenylglycinol; Calix[4]arene; CSP; HPLC; pi-Acidic; pi-Basic; Oxazolidinone | ENANTIOMERIC EXCESS; SEPARATION; CHROMATOGRAPHY; RECOGNITION; CALIXARENES; DERIVATIVES; DRUGS; ACIDS | (R)-phenylglycinol; Calix[4]arene; CSP; HPLC; Oxazolidinone; π-Acidic; π-Basic | Aromatic hydrocarbons; Chlorine compounds; High performance liquid chromatography; Calix[4]arenes; Chiral oxazolidinones; Chiral stationary phase; Chiral stationary phasis; Enantioseparations; Methylcalix[4]resorcinarene; Stationary phase; Steric interactions; Separation | English | 2020 | 2020-07 | 10.1002/bkcs.12063 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Epidemiologic Characteristics of Work-related Eye Injuries and Risk Factors Associated with Severe Eye Injuries: A Registry-based Multicentre Study | Purpose: Work-related eye injuries have been reported with a variety of epidemiologic and clinical characteristics. We aimed to identify epidemiologic characteristics of work-related eye injuries and risk factors associated with severe injury in a large metropolitan city. Methods: This multicentre, retrospective, observational study used a prospective eye injury registry. We included patients with work-related eye injuries at four tertiary teaching hospitals in Daegu, South Korea, between August 2016 and July 2018. Severe injuries were defined as subjects fulfilled one or more of the following criteria: 1) presented with open globe injury; 2) required emergency eye surgery or observation after hospitalization; 3) developed eye injury-associated complications or 4) impaired final visual acuity. Results: The study included 1,424 patients. One hundred seventy-three patients (12.1%) had severe injuries. The median age and interquartile range (IQR; 25th and 75th percentiles) of the subjects were 48.0 years (IQR, 36.0-57.0), and the majority (91.9%) were male. Among the subjects, 61 patients (4.2%) suffered eye injuries despite the use of protective eyewear at the time of injury. Multivariable logistic regression analysis revealed age >= 70 years (odds ratio: 4.02, 95% confidence interval: 1.77-9.15), hammering/nailing (6.80, 2.80-16.53), and mowing (4.87, 1.77-9.15) as activities that conferred a high risk of ocular trauma with severe injury. Conclusion: Age over 70 years, hammering/nailing, and mowing were risk factors for severe injury from work-related ocular trauma. Severe eye injury could occur in spite of the use of protective eyewear; appropriate, well-fitting protective eyewear should be emphasized in the future. | Ahn, Jae Yun; Ryoo, Hyun Wook; Park, Jung Bae; Moon, Sungbae; Cho, Jae Wan; Park, Dong Ho; Lee, Won Kee; Kim, Jung Ho; Jin, Sang Chan; Lee, Kyung Woo; Kim, Jong-Yeon | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Med Res Collaborat, Sch Med, Dept Biostat, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Emergency Med, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Emergency Med, Daegu, South Korea; Keimyung Univ, Sch Med, Dongsan Med Ctr, Dept Emergency Med, Daegu, South Korea; Daegu Catholic Univ, Sch Med, Dept Prevent Med, Daegu, South Korea | Kim, Jung Ho/LDE-9088-2024; Ahn, Jae Yun/N-2652-2017; Kim, Jungho/LDE-9088-2024 | 56937505400; 55350557500; 57189030435; 57191584601; 7403536065; 36676632900; 22953484700; 57205704177; 57205700670; 56116804300; 58382951500 | ryoo@knu.ac.kr; | OPHTHALMIC EPIDEMIOLOGY | OPHTHAL EPIDEMIOL | 0928-6586 | 1744-5086 | 27 | 2 | SCIE | OPHTHALMOLOGY | 2020 | 1.648 | 84.7 | 1.29 | 2025-06-25 | 17 | 17 | Eye injuries; occupational injuries; risk factors; personal protective equipment; epidemiology | OCULAR TRAUMA; PROTECTION; SAFETY; HEALTH | epidemiology; Eye injuries; occupational injuries; personal protective equipment; risk factors | Adult; Aged; Emergency Treatment; Eye Injuries; Female; Hospitalization; Humans; Incidence; Male; Middle Aged; Occupational Injuries; Ophthalmologic Surgical Procedures; Personal Protective Equipment; Prospective Studies; Registries; Republic of Korea; Retrospective Studies; Risk Factors; Trauma Severity Indices; Vision Disorders; abrasion; adult; aged; Article; burn; canalicular laceration; chemical burn; conjunctiva disease; cornea injury; corneoscleral laceration; emergency surgery; eye injury; eye surgery; eyeball; eyelid disease; female; follow up; grinding; high risk patient; hospitalization; human; hyphema; injury severity; intraocular foreign body; laceration; major clinical study; male; metal industry; middle aged; observational study; occupational accident; occupational hazard; orbit fracture; penetrating trauma; perforating eye injury; priority journal; punctate keratitis; register; retina detachment; retina edema; retina hemorrhage; retrobulbar hemorrhage; retrospective study; sclera disease; South Korea; subconjunctival hemorrhage; superficial punctate keratitis; teaching hospital; traumatic cataract; visual acuity; visual impairment; vitreous hemorrhage; welding; clinical trial; comparative study; complication; emergency treatment; eye injury; incidence; injury scale; multicenter study; occupational accident; procedures; prospective study; protective equipment; risk factor; visual disorder | English | 2020 | 2020-03-03 | 10.1080/09286586.2019.1683868 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Sodium reduction in South Korean restaurants: A Daegu-based intervention project | Background and Objectives: Koreans tend to have high sodium intake in restaurants. This study assessed the effect of the sodium reduction project in restaurants in Daegu Metropolitan City. Methods and Study Design: A total of 156 sodium reduction menu items offered by 90 restaurants were categorized into 11 food groups to compare sodium content and salinity before and after the project. In total, 162 owners and staff members of the restaurants, as well as 727 of their customers, were surveyed on their perceptions of and satisfaction with the sodium reduction project. Results: Average salinity of the menu items was significantly reduced from 0.70% prior to the project to 0.49% after the project (p<0.001), and average sodium content was also significantly reduced from 1,470 mg to 980 mg (p<0.001). The food groups with the highest sodium reduction rate were soups (46.0%) and grilled dishes (39.5%), with an average sodium reduction rate of 36.1%. The restaurant owners' average satisfaction score with the project was 39.6 points (out of 50). Customers responded that the sodium reduction menus were moderate (62.4%) and bland (27.9%), and the taste was good (48.9%) and excellent (25.0%). Approximately 52.0% and 18.6% of customers were satisfied and very satisfied, respectively, with the sodium reduction menu. Conclusions: Overall, the sodium reduction project in restaurants in Daegu had a positive effect because it successfully reduced the sodium content of food while also boosting the satisfaction of the restaurant owners and staff and their customers with the project. | Ma, Jian; Lee, Sujin; Kim, Kilye; Lee, Yeon-Kyung | Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu 41566, South Korea | Lee, Yeon-Kyung/AAA-1916-2020; Ma, Jian/HLW-5119-2023 | 57218175449; 57210888405; 57218175604; 16301462200 | yklee@knu.ac.kr; | ASIA PACIFIC JOURNAL OF CLINICAL NUTRITION | ASIA PAC J CLIN NUTR | 0964-7058 | 1440-6047 | 29 | 2 | SCIE | NUTRITION & DIETETICS | 2020 | 1.662 | 84.7 | 0.37 | 2025-06-25 | 4 | 5 | restaurant menu; eating out; salinity; sodium content; sodium reduction | BLOOD-PRESSURE; HEALTH; FOOD; EXCRETION; RISK | Eating out; Restaurant menu; Salinity; Sodium content; Sodium reduction | Consumer Behavior; Diet, Sodium-Restricted; Food Labeling; Humans; Nutritional Requirements; Republic of Korea; Restaurants; Surveys and Questionnaires; catering service; consumer attitude; food packaging; human; nutritional requirement; questionnaire; sodium restriction; South Korea | English | 2020 | 2020-07 | 10.6133/apjcn.202007_29(2).0023 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | Clinical factors that influence the occurrence of symptomatic pseudoaneurysms and arteriovenous fistulas after partial nephrectomy: multi-institutional study of renal function outcomes after one year of selective arterial embolization | Purpose: Renal artery pseudoaneurysms (RAPs) and arteriovenous fistulas (AVFs) are rare but potentially life-threatening complications after partial nephrectomy (PN). Selective arterial embolization (SAE) is an effective method for controlling RAPs/AVFs. We assessed the clinical factors affecting the occurrence of RAPs/AVFs after PN and the effects of SAE on postsurgical renal function. Materials and Methods: Four hundred ninety-three patients who underwent PN were retrospectively reviewed. They were placed in either the SAE or the non-SAE group. The effects of clinical factors, including R.E.N.A.L. scores, on the occurrence of RAPs/AVFs were analyzed. The influence of SAE on the estimated glomerular filtration rate (eGFR) during the first postoperative year was evaluated. Results: Thirty-three (6.7%) patients experienced RAPs/AVFs within 8 days of the median interval between PN and SAE. The SAE group had significantly higher R.E.N.A.L. scores, higher N component scores, and higher L component scores (all, p <0.05). In the multivariate analysis, higher N component scores were associated with the occurrence of RAPs/AVFs (Odds ratio: 1.96, p=0.039). In the SAE group, the mean 3-day postembolization eGFR was significantly lower than the mean 3-day postoperative eGFR (p <0.01). This difference in the eGFRs was still present 1 year later. Conclusions: Renal tumors located near the renal sinus and collecting system were associated with a higher risk for RAPs/AVFs after PN. Although SAE was an effective method for controlling symptomatic RAPs/AVFs after PN, a procedure-related impairment of renal function after SAE could occur and still be present at the end of the first postoperative year. © 2020.

| ○ | ○ | Article | Three-phase flying-capacitor MMC with six coupled inductors | In this paper, the design and integration of coupled inductors have been proposed for a flying-capacitor (FC) modular multilevel converter (MMC) for induction motor drive applications. In the conventional three-phase FC-MMC, twelve discrete inductors are needed for three legs. However, by integrating one coupled inductor with two windings in two half-arms, the number of inductors required is reduced from 12 to 6. Accordingly, the overall volumes and weights of cores and windings can be reduced by 41.7% and 41.4% when compared with discrete inductors. To confirm the validity of the proposed coupled inductor, a 4160-V/1-MW simulation model of a FC-MMC and a 220-V/3-kW scaled-down prototype have been built, of which performance for induction motor drives has been tested from standstill to the rated speed. | Le, Duc Dung; Lee, Dong-Choon; Kim, Heung-Geun | Yeungnam Univ, Dept Elect Engn, Gyongsan, South Korea; Kyungpook Natl Univ, Dept Elect Engn, Daegu, South Korea | LE, DUCDUNG/GPS-7210-2022; Lee, Dong-Choon/L-6825-2019 | 57210831963; 8510130400; 7410122126 | dclee@yu.ac.kr; | JOURNAL OF POWER ELECTRONICS | J POWER ELECTRON | 1598-2092 | 2093-4718 | 20 | 4 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2020 | 1.114 | 85.2 | 0.36 | 2025-06-25 | 4 | 6 | Coupled inductor; Flying-capacitor modular multilevel converters (FC-MMC); Medium-voltage motor drives; Submodule (SM) capacitor; Voltage ripple | MODULAR MULTILEVEL CONVERTERS; VOLTAGE; OPERATION; DESIGN | Coupled inductor; Flying-capacitor modular multilevel converters (FC-MMC); Medium-voltage motor drives; Submodule (SM) capacitor; Voltage ripple | Electric drives; Electric motors; Induction motors; Winding; Coupled inductor; Design and integrations; Flying capacitor; Induction motor drive; Modular multi-level converters; Simulation model; Three phase; Electric inductors | English | 2020 | 2020-07 | 10.1007/s43236-020-00099-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
