| ○ | ○ | Review | Advances and key considerations of liquid chromatography-mass spectrometry for porcine authentication in halal analysis | The halal food industries are rapidly expanding to fulfill global halal demands. Non-halal substances such as porcine proteins are often added intentionally or unintentionally to products. The development of highly selective and sensitive analytical tools is necessary, and liquid chromatography-mass spectrometry is a powerful tool that can cope with the challenge. The LC-MS method has great potential for halal authentication, because it has high sensitivity and low detection limit and detects several species markers and different tissue origins at once within one species. This article provides an understanding of recent advances in the application of LC-MS for the improvement of porcine authentication. Sample preparation, marker selection, separation and mass spectrometry conditions, quantitative assessment, and data processing for protein identification were all covered in detail to choose the most suitable method for the analytical needs. | Dewi, Kifayati Rosiyanti; Ismayati, Maya; Solihat, Nissa Nurfajrin; Yuliana, Nancy Dewi; Kusnandar, Feri; Riantana, Handy; Heryani, Heryani; Halim, Abdul; Acter, Thamina; Uddin, Nizam; Kim, Sunghwan | Natl Res & Innovat Agcy BRIN, Res Ctr Biomass & Bioprod, Jl Raya Bogor Km 46, Bogor 16911, Indonesia; IPB Univ, Dept Food Sci & Technol, Jl Kamper, Bogor 16680, Indonesia; Natl Res & Innovat Agcy BRIN, Integrated Lab Bioprod iLaB, Jl Raya Bogor Km 46, Bogor 16911, Indonesia; Indonesian Council Ulama LPPOM MUI, Assessment Inst Foods Drugs & Cosmet, Jl Pemuda 5, Bogor 16161, Indonesia; Univ Int Semen Indonesia, Dept Chem Engn, Jl Vet, Gresik 61122, Indonesia; East West Univ, Dept Math & Phys Sci, A-2 Jahurul Islam Ave, Dhaka 1212, Bangladesh; Daffodil Int Univ, Dept Nutr & Food Engn, Dhaka 1216, Bangladesh; Kyungpook Natl Univ, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea; Mass Spectrometry Convergence Res Ctr, Daegu, South Korea; Green Nano Mat Res Ctr, Daegu, South Korea | Kusnandar, Feri/GPK-5271-2022; Kim, Sunghwan/HKN-9812-2023; Uddin, Nizam/N-3536-2014; ismayati, maya/AAS-1425-2020; Uddin, Dr. Nizam/N-3536-2014; Yuliana, Nancy Dewi/GQP-7950-2022; Solihat, Nissa/GVT-7174-2022; Halim, Abdul/AAX-9287-2020 | 58115278400; 55760114200; 57199653322; 26424117400; 37044882400; 57411708500; 57221443567; 57193623688; 56768064900; 57188533756; 57203772967 | maya.ismayati@brin.go.id;sunghwank@knu.ac.kr; | JOURNAL OF ANALYTICAL SCIENCE AND TECHNOLOGY | J ANAL SCI TECHNOL | 2093-3134 | 2093-3371 | 14 | 1 | SCIE | CHEMISTRY, ANALYTICAL | 2023 | 2.5 | 54.2 | 0.37 | 2025-06-18 | 6 | 8 | Porcine; Halal authentication; LC-MS | MARKER PEPTIDES; SENSITIVE DETECTION; CRUDE-OIL; LC-MS/MS; MEAT; GELATIN; PORK; MS; IDENTIFICATION; QUANTIFICATION | Halal authentication; LC–MS; Porcine | English | 2023 | 2023-02-20 | 10.1186/s40543-023-00376-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficacy and safety of 1% and 2% rebamipide clear solution in dry eye disease: a multicenter randomized trial | BackgroundTo evaluate the efficacy of 1% and 2% rebamipide clear solution in the treatment of dry eye disease (DED).MethodsTwo hundred twenty patients with DED were randomly assigned to one of three groups: the 1% rebamipide, 2% rebamipide, or placebo (eye drops containing the same ingredients, except for the active components). Each eye drop was instilled four times daily for 12 weeks. Changes in tear film break-up time (TBUT), corneal and conjunctival staining score, Schirmer 1 test, and the Ocular Surface Disease Index (OSDI) from baseline to 12-week visit between the study groups were compared for efficacy assessment.ResultsThe mean age of study patients was 43.8 & PLUSMN;14.2 years. The 1% and 2% rebamipide groups showed greater improvement in TBUT (1.99 & PLUSMN;1.87 and 2.02 & PLUSMN;2.21 s) at 12 weeks from baseline than the placebo group (1.25 & PLUSMN;2.93 s). The 2% rebamipide group showed greater improvement in the corneal staining score (- 3.15 & PLUSMN;2.00) at 12 weeks from baseline than the placebo group (- 2.85 & PLUSMN;1.80). The 1% and 2% rebamipide groups showed improvement in Schirmer 1 test (1.27 & PLUSMN;3.86 and 1.50 & PLUSMN;4.14 mm) at 12 weeks of treatment, but not the placebo group (0.55 & PLUSMN;2.99 mm). Both the rebamipide groups and the placebo group showed significantly improved OSDI after treatment for 12 weeks; however, there was no significant difference among the three groups.Conclusions1% and 2% rebamipide clear solutions are an effective therapeutic option for improving TBUT and tear volume, and stabilizing the corneal staining score in DED. | Eom, Youngsub; Chung, So Hyang; Chung, Tae-Young; Kim, Jae Yong; Choi, Chul Young; Yoon, Kyung Chul; Ko, Byung Yi; Kim, Hong Kyun; Kim, Mee Kum; Lee, Hyung Keun; Song, Jong Suk; Hyon, Joon Young; Seo, Kyoung Yul; Lee, Jong Soo; Kim, Hyo Myung | Korea Univ, Dept Ophthalmol, Coll Med, Seoul, South Korea; Korea Univ, Dept Ophthalmol, Ansan Hosp, Ansan, Gyeonggi Do, South Korea; Catholic Univ Korea, Seoul St Marys Hosp, Coll Med, Dept Ophthalmol, Seoul, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Dept Ophthalmol, Sch Med, Seoul, South Korea; Univ Ulsan, Asan Med Ctr, Dept Ophthalmol, Coll Med, Seoul, South Korea; Sungkyunkwan Univ, Kangbuk Samsung Hosp, Dept Ophthalmol, Sch Med, Seoul, South Korea; Chonnam Natl Univ, Dept Ophthalmol, Med Sch, Gwangju, South Korea; Konyang Univ, Dept Ophthalmol, Coll Med, Daejeon, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Seoul Natl Univ, Dept Ophthalmol, Coll Med, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Ophthalmol, Seoul, South Korea; Yonsei Univ, Gangnam Severance Hosp, Dept Ophthalmol, Coll Med, Seoul, South Korea; Korea Univ Guro Hosp, Dept Ophthalmol, Seoul, South Korea; Seoul Natl Univ, Dept Ophthalmol, Bundang Hosp, Seongnam, South Korea; Yonsei Univ, Severance Hosp, Dept Ophthalmol, Coll Med, Seoul, South Korea; Pusan Natl Univ, Dept Ophthalmol, Coll Med, Pusan, South Korea; Korea Univ Anam Hosp, Dept Ophthalmol, Seoul, South Korea | Seo, Kyoung/I-5484-2019; Kim, Mee/J-5394-2012; Choi, Chul Young/O-1208-2016; Hyon, Joon/J-5720-2012; , James/ABG-8160-2020; Chung, Ho/J-5656-2012 | 55504436000; 8983355200; 7401571091; 15923054800; 14522006600; 7401607582; 55554975800; 57218260940; 7406090096; 57283576400; 7404786554; 6507588001; 7201839260; 57219085131; 57877893300 | hyomk@korea.ac.kr; | BMC OPHTHALMOLOGY | BMC OPHTHALMOL | 1471-2415 | 23 | 1 | SCIE | OPHTHALMOLOGY | 2023 | 1.7 | 54.2 | 2.93 | 2025-06-25 | 7 | 9 | Dry Eye Disease; Quinolones; Cornea; Tears; Intraocular pressure | OCULAR SURFACE; OPHTHALMIC SOLUTION; OPC-12759; 0.1-PERCENT; INCREASES; BIOSYNTHESIS; SECRETION; DIAGNOSIS; TEAR | Cornea; Dry Eye Disease; Intraocular pressure; Quinolones; Tears | Adult; Alanine; Dry Eye Syndromes; Humans; Middle Aged; Ophthalmic Solutions; Quinolones; Tears; alanine; eye drops; quinolone derivative; rebamipide; adult; clinical trial; controlled study; dry eye syndrome; human; lacrimal fluid; middle aged; multicenter study; randomized controlled trial | English | 2023 | 2023-08-03 | 10.1186/s12886-023-03004-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Optimization and Kinetic Study of Treating Dye-Contaminated Wastewater Using Bio-Composite Synthesized from Natural Waste | The main objective of the present research project was to investigate the possibility of using low cost, eco-friendly, and easily available adsorbents, such as mint biomass and marble stone waste, for the removal of dyes, DRIM blue HS-RL and DRIM black ep-B, from wastewater using an efficient procedure, which is adsorption. Nine different combinations of these adsorbents were prepared with and without modification using sodium metasilicate and potassium ferricyanide. Spectroscopic analysis was carried out to investigate the & lambda;(max) of the dyes. Adsorbent nanocomposites were characterized using Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM) and zeta (& zeta;) potential. Adsorption equilibrium studies were investigated by determining the adsorption at the following conditions: initial dye concentrations (5-50 ppm), adsorbent doses (0.005-0.5 g), contact times (15-240 min), temperatures (30-70 & DEG;C) and pH (5-10). Of all the nine adsorbents, MTPF showed the maximum adsorption capacity at 50 ppm initial dye concentration, 0.005 g dosage of adsorbent and 240 min contact time for both dyes. DRIM Blue HS-RL was adsorbed efficiently at 6 pH and temperature 60 & DEG;C and DRIM black ep-B was adsorbed at pH 5 and temperature 50 & DEG;C by MTPF (mint-tawera composite treated with potassium ferricyanide). Among the various adsorption isotherms (Langmuir, Dubinin-Radushkevich, Freundlich, Herkin-Jura, and Temkin isotherms), some adsorbent followed the Freundlich isotherm while the others followed the Langmuir isotherm. The best-fit model was decided based on their high R-2 value and agreement between q(e) calculated from isotherms and those obtained experimentally. At equilibrium concentration, application of kinetic models (pseudo-first-order, and pseudo-second-order) revealed that the best-fit model was pseudo-second-order kinetic model for both dyes, as their R-2 > 0.9, and q(e) calculated was close to q(e) obtained experimentally. | Iqbal, Mana; Hanif, Muhammad Asif; Rashid, Umer; Jilani, Muhammad Idrees; Alharthi, Fahad A.; Kazerooni, Elham Ahmed | Univ Agr Faisalabad, Dept Chem, Nano & Biomat Lab, Faisalabad 38040, Pakistan; Univ Putra Malaysia, Inst Nanosci & Nanotechnol ION2, Serdang 43400, Selangor, Malaysia; Chulalongkorn Univ, Fac Sci, Ctr Excellence Catalysis Bioenergy & Renewable Che, Bangkok 10330, Thailand; Univ Lahore, Dept Chem, Lahore 54000, Pakistan; King Saud Univ, Coll Sci, Chem Dept, Riyadh, Saudi Arabia; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea | ; Rashid, Umer/C-9986-2011; Hanif, Muhammad Asif/AAA-9846-2019 | 58509897400; 58399216100; 16031556400; 55540126000; 57200522309; 57191375873 | minaiqbal29@gmail.com;drmuhammadasifhanif@gmail.com;umer.rashid@upm.edu.my;idreeschemistry@gmail.com;fharthi@ksu.edu.sa;elham.ghasemi.k@gmail.com; | SEPARATIONS | SEPARATIONS | 2297-8739 | 10 | 7 | SCIE | CHEMISTRY, ANALYTICAL | 2023 | 2.5 | 54.2 | 0.45 | 2025-06-25 | 4 | 5 | adsorption; mint biomass; stone waste; DRIM blue; DRIM black | LOW-COST ADSORBENTS; METHYLENE-BLUE; AQUEOUS-SOLUTIONS; ADSORPTION-KINETICS; ACTIVATED CARBON; HEAVY-METALS; MARBLE DUST; REMOVAL; ISOTHERMS; POLLUTANT | adsorption; DRIM black; DRIM blue; mint biomass; stone waste | English | 2023 | 2023-07 | 10.3390/separations10070386 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Polyamide 6/MXene-grafted graphene oxide hybrid nanocomposites | Polymer nanocomposites offer a way to bridge the gap between nanomaterials and macroscale materials. Nanocomposites based on MXene (2D transition metal carbide, nitride, or carbonitride) and graphene are a hot topic in the fields of materials and chemistry because of their unique properties. In this research, MXene and graphene oxide were modified by acidified 6-aminocaproic acid and hexamethylene diamine, respectively. The modified MXene and graphene oxide were hybridized through condensation reaction to give MXene-grafted graphene oxide (MXene-g-GO). The resulting MXene-g-GO hybrid filler was further blended with commercial polyamide 6 (PA6). The effects of MXene, grapheme oxide and MXene-grafted graphene oxide on thermal stability, mechanical properties and electromagnetic interference shielding efficiency of PA6 were investigated through material characterization and relevant tests. The pattern of SEM, XRD and XPS demonstrated that modified MXene (mMXene) was grafted to the surface of modified graphene oxide (mGO) successfully. The results of TGA and mechanical experiments showed that MXene and graphene have a certain synergistic effect on some properties of polyamide 6 nanocomposites and aggregation between the fillers was alleviated. Besides, PA6 nanocomposites, having improved electromagnetic interference shielding efficiency, can be prepared using hybridized fillers. This study introduced a polymer material that can be used to make the external shell of the communication device, which has a specific reference value to control harming of the electromagnetic waves. | Lee, Dong-Eun; Lee, Gwan Hui; Son, Na Rae; Zhang, He-Xin; Yoon, Keun-Byoung | Kyungpook Natl Univ, Sch Architecture & Civil & Architectural Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Anhui Univ Technol, Sch Chem & Chem Engn, Maanshan, Peoples R China | Hexin, Zhang/ACI-3911-2022 | 56605563300; 57201689364; 58093392100; 25633288200; 7401607550 | hxzhang@ahut.edu.cn;kbyoon@knu.ac.kr; | IRANIAN POLYMER JOURNAL | IRAN POLYM J | 1026-1265 | 1735-5265 | 32 | 4 | SCIE | POLYMER SCIENCE | 2023 | 2.4 | 54.2 | 1.39 | 2025-06-25 | 11 | 11 | PA6; MXene; Nanomaterial; Graphene oxide; Polymer | ZIEGLER-NATTA CATALYST; IN-SITU POLYMERIZATION; THERMAL-PROPERTIES; CARBON NANOTUBES; PERFORMANCE; COMPOSITES; FACILE; MXENE; SUPERCAPACITORS; NANOPLATELETS | Graphene oxide; MXene; Nanomaterial; PA6; Polymer | Amines; Carbides; Carbon nitride; Condensation reactions; Efficiency; Electromagnetic pulse; Electromagnetic shielding; Electromagnetic wave interference; Grafting (chemical); Graphene; Magnesia; Signal interference; Thermodynamic stability; Transition metals; Electromagnetic interference shielding; Graphene oxides; Hybrid nanocomposites; Macroscales; Mmxene; Polyamide 6; Polymer nanocomposite; Polymer-nanocomposite; Property; Shielding efficiency; Nanocomposites | English | 2023 | 2023-04 | 10.1007/s13726-022-01119-8 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Sirtuin 3 mutation- induced mitochondrial dysfunction and optic neuropathy: a case report | BackgroundMitochondrial optic neuropathy is characterized by painless, progressive, symmetrical central vision loss, and dyschromatopsia owing to mitochondrial dysfunction. This report documents a rare case of mitochondrial optic neuropathy due to the SIRT3 gene mutation.Case presentationThis report describes a case of a 17-year-old boy who presented with symptoms of bilateral painless, progressive vision decline over several years. Fundus examination revealed temporal pallor of the optic nerve head in both the eyes and an OCT showed considerable thinning of the retinal nerve fiber and ganglion cell layers. Pathogenicity was confirmed by decreased mitochondrial function measured by bioenergetic health index and oxygen consumption rate in this patient. Subsequent NGS revealed a missense mutation of the SIRT3 gene (c.1137G > C, p.Trp379Cys) in the patient.ConclusionsThis case describes the clinical manifestation of mitochondrial optic neuropathy due to the SIRT3 gene mutation. | Chun, Bo Young; Choi, Jung Moon; Hwang, Su-Kyeong; Rhiu, Soolienah | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Sch Med, 680 Gukchaebosang St, Daegu 700422, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Dept Ophthalmol, Coll Med, Hwaswong, South Korea | 25644902100; 58158624700; 37761570400; 36554769100 | byjun424@hotmail.com;soolienah99@naver.com; | BMC OPHTHALMOLOGY | BMC OPHTHALMOL | 1471-2415 | 23 | 1 | SCIE | OPHTHALMOLOGY | 2023 | 1.7 | 54.2 | 0.65 | 2025-06-25 | 2 | 2 | Mitochondrial dysfunction; Mitochondrial optic neuropathy; SIRT3 gene mutation; Case report | Case report; Mitochondrial dysfunction; Mitochondrial optic neuropathy; SIRT3 gene mutation | Adolescent; Humans; Male; Mitochondria; Mutation; Optic Nerve; Optic Nerve Diseases; Sirtuin 3; sirtuin 3; adolescent; case report; genetics; human; male; mitochondrion; mutation; optic nerve; optic nerve disease | English | 2023 | 2023-03-24 | 10.1186/s12886-023-02872-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | The subjective controllability of exotropia and its effect on surgical outcomes in patients with intermittent exotropia | Background/aims We evaluate the clinical characteristics of intermittent exotropia with controllability and compare surgical outcomes between patients with and without controllability. Methods We reviewed the medical records of patients aged 6-18 years with intermittent exotropia who underwent surgery between September 2015 and September 2021. Controllability was defined as the patient's subjective awareness of exotropia or diplopia associated with the presence of exotropia and ability to instinctively correct the ocular exodeviation. Surgical outcomes were compared between patients with and without controllability, with a favorable surgical outcome defined as an ocular deviation between <= 10 PD of exotropia and <= 4 PD of esotropia at distance and near. Results Among 521 patients, 130 (25%, 130/521) had controllability. The mean age of onset (7.7 years) and surgery (9.9 years) were higher in patients with controllability than in those without controllability (p < 0.001). The mean control scores of patients with controllability (distance: 1.9, near: 1.5) were lower compared with patients without controllability (distance: 3.0, near: 2.2), reflecting a better level of control. Patients with controllability had a better surgical outcome than those without controllability, as analyzed by log-rank test (p < 0.001). Larger preoperative ocular exodeviation at distance (hazard ratio [HR] = 1.083, confidence interval [CI] = 1.018-1.151, p = 0.012) and near (HR = 1.102, CI = 1.037-1.172, p = 0.002) were significantly related to recurrence in patients with controllability. Conclusions Patients with controllability showed better surgical outcomes, later exotropia onset, and better level of control than patients without controllability. Preoperative ocular exodeviation was a significant factor influencing favorable outcomes in patients with controllable exotropia. | Kim, Mirae; Kim, Hong Kyun; Kim, Won Jae | Nune Eye Hosp, Daegu, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Ophthalmol, Daegu, South Korea | 58161945100; 57218260940; 56266756200 | eyfuture@naver.com;eyekwj@gmail.com; | BMC OPHTHALMOLOGY | BMC OPHTHALMOL | 1471-2415 | 23 | 1 | SCIE | OPHTHALMOLOGY | 2023 | 1.7 | 54.2 | 0.65 | 2025-06-25 | 2 | 2 | Control; Exotropia; Surgical outcomes | Control; Exotropia; Surgical outcomes | Child; Exotropia; Follow-Up Studies; Humans; Oculomotor Muscles; Ophthalmologic Surgical Procedures; Retrospective Studies; Treatment Outcome; Vision, Binocular; binocular vision; child; divergent strabismus; extraocular muscle; eye surgery; follow up; human; retrospective study; treatment outcome | English | 2023 | 2023-03-28 | 10.1186/s12886-023-02873-w | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Electrochemical behavior of anodic nano-structured titania synthesized from stirred and unstirred electrolytes | Titanium was anodically oxidized in aqueous electrolyte containing dissolved 1 M -Na2SO4 and 0.5 wt% NaF. This oxidation was performed for 0.5 and 1 h at 20 and 30 V in unstirred and magnetic pellet stirred baths. Irrespective of the stirring conditions, amorphous, nanotubular oxide was formed at 20 V. Compared to the unstirred condition, the tubular length was increased upon stirring at 20 V. However, flat, anatase layers were produced at 30 V in both stirring conditions. The nanotube network was formed probably in first 5 min and disturbed later, so that the oxidation proceeds laterally and perpendicular to the longitudinal tubular axis. Among the oxides tested, the oxide films obtained by oxidation for 0.5 h at 20 and 30 V under stirring condition (M20, 0.5 and M30, 0.5) have higher impedance and lower corrosion current density in simulated body fluid (SBF). The SBF represents the actual conditions of fluid inside the body. | Narayanan, Ramaswamy; Panigrahi, Mrutyunjay; Tae-Yub, Kwon | Vellore Inst Technol, Sch Mech Engn, Chennai 600127, Tamil Nadu, India; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 700412, South Korea | Panigrahi, Mrutyunjay/AAB-3113-2020 | 7202724072; 36775104000; 7202206084 | mrutyunjayjapan@gmail.com; | JOURNAL OF MATERIALS RESEARCH | J MATER RES | 0884-2914 | 2044-5326 | 38 | 12 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 2.7 | 54.3 | 0.12 | 2025-06-25 | 1 | 1 | ORGANIZED TIO2 NANOTUBES; OXIDE NANOTUBES; MORPHOLOGY; COATINGS; ALLOYS; GROWTH; FILMS | Impedance; Nanotube; Polarization; Stirring; Titanium | Body fluids; Corrosion; Electrolytes; Oxidation; Oxide films; Sodium sulfate; Titanium; Titanium dioxide; Aqueous electrolyte; Electrochemical behaviors; Impedance; Nano-structured; Simulated body fluids; Stirring; Stirring conditions; Synthesised; Titania; Tubulars; Nanotubes | English | 2023 | 2023-06-28 | 10.1557/s43578-023-01040-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sonication-assisted ion-intercalation exfoliation of MoS2 quantum dots | Synthesis of MoS2 quantum dots (QDs) by a sonication-assisted ion-intercalation process where sodium hydroxide (NaOH) is used as sodium (Na+) and hydroxyl (OH-) ions source for the intercalation purpose is reported. The exfoliation method results in well-exfoliated mono- to few-layered QDs as illustrated by the atomic force microscopy (AFM) measurements, showing a thickness of < 1.6 nm, and confirmed by X-ray diffraction (XRD) studies where the characteristic peak at 2 theta = 14.4 degrees of bulk 2H-MoS2 disappears. The Raman spectroscopy measurements of the QDs show a frequency difference of 19.8 cm(-1) between the E and A(1g) vibration modes and are in good agreement with the AFM and XRD results. The reported exfoliation technique resulted in an improvement of similar to 7% in production yield with a total production yield of similar to 20%, higher than the previous reports. The QDs have average lateral size of 3.7 +/- 1.0 nm as determined from the HRTEM images. | Ali, Luqman; Lee, Yong Joong; Kim, Jong Su; Byeon, Clare Chisu | Kyungpook Natl Univ, Grad Sch, Dept Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Yeungnam Univ, Dept Phys, Gyongsan 38541, South Korea | ALI, LUQMAN/LDF-2311-2024 | 57212543197; 57183248500; 55863440700; 55987812100 | byeon@knu.ac.kr; | JOURNAL OF MATERIALS RESEARCH | J MATER RES | 0884-2914 | 2044-5326 | 38 | 20 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 2.7 | 54.3 | 0.49 | 2025-06-25 | 3 | 4 | MoS2 quantum dots; Ion intercalation; Ultrasonication-assisted exfoliation; Na-ions intercalation; Production yield | HYDROGEN EVOLUTION REACTION; MONOLAYER MOS2; ELECTRONIC STATES; LARGE-AREA; NANOSHEETS; FACILE | Ion intercalation; MoS<sub>2</sub> quantum dots; Na-ions intercalation; Production yield; Ultrasonication-assisted exfoliation | Exfoliation (materials science); Ions; Layered semiconductors; Nanocrystals; Semiconductor quantum dots; Sodium hydroxide; X ray diffraction; Atomic-force-microscopy; Intercalation process; Ion intercalation; MoS2 quantum dot; Na+ ions; Na-ion intercalation; Production yield; Ultra-sonication; Ultrasonication-assisted exfoliation; Molybdenum compounds | English | 2023 | 2023-10-28 | 10.1557/s43578-023-01178-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | System-Level Robust Design Optimization of a Permanent Magnet Motor Under Design Parameter Uncertainties | In the presence of design parameter uncertainties, a system-level robust design optimization (RDO) method for a permanent magnet motor is proposed to enhance the dynamic and steady performances of a whole motor drive system. To achieve the goal, the influence of individual motor parameters on transient system responses is first investigated with the method of Taguchi experimental planning. The temperature-dependent material property of each motor component is then examined around an operating temperature.

| ○ | ○ | Article | Trailing edge serrations for noise control in axial-flow automotive cooling fans | This study investigated the use of trailing edge serrations to reduce the noise generated by axial-flow automotive cooling fans. Three different serration profiles (sinusoidal, rectangular, and triangular) were examined, with the profiles being extended radially along the entire blade length and truncated at half the blade length while keeping the dimensionless wave number k* and wave amplitude 2h* constant. The simulations employed a hybrid URANS-LES solver for the flow field and Ffowcs Williams-Hawkings analogy for the sound field, corresponding to the maximum volumetric flow rate and fan rotational speed. Acoustic pressure measurements were taken at multiple receivers upstream and downstream of the fan, and the overall sound pressure level was computed based on the results. Furthermore, the study also compared the aerodynamic performance of all serration types with the baseline fan, revealing that the baseline fan was relatively more efficient than their serrated counterparts. Despite the reduced efficiency, the trailing edge serrations offered significant noise reduction benefits of up to 10 dB, making them a promising solution for improving acoustic comfort in automotive cooling systems. | Hur, Kwang Ho; Haider, Basharat Ali; Sohn, Chang Hyun | Kyungpook Natl Univ, Sch Mech Engn, 80 Daehak Ro, Daegu 41566, South Korea | Haider, Basharat Ali/B-5887-2015; Haider, Basharat/B-5887-2015 | 57218394416; 36805990000; 36806852600 | bahaider@knu.ac.kr;chsohn@knu.ac.kr; | INTERNATIONAL JOURNAL OF AEROACOUSTICS | INT J AEROACOUST | 1475-472X | 2048-4003 | 22 | 7-8 | SCIE | ACOUSTICS;ENGINEERING, AEROSPACE;MECHANICS | 2023 | 1.2 | 54.8 | 0.55 | 2025-06-25 | 2 | 3 | Acoustic comfort; automotive aeroacoustics; axial-flow cooling fan; noise reduction; trailing edge serration | TIP SPEED; PREDICTION; TURBULENCE; SOUND | Acoustic comfort; automotive aeroacoustics; axial-flow cooling fan; noise reduction; trailing edge serration | Acoustic fields; Acoustic noise; Aeroacoustics; Axial flow; Axial flow turbomachinery; Cooling; Cooling systems; Fans; Flow rate; Acoustic comfort; Automotive aeroacoustic; Automotives; Axial-flow cooling fan; Cooling fans; Trailing edge serration; Trailing edges; Wave amplitudes; Wave numbers; Williams; Noise abatement | English | 2023 | 2023-11 | 10.1177/1475472x231206498 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Efficient Partial Weight Update Techniques for Lightweight On-Device Learning on Tiny Flash-Embedded MCUs | Typical training procedures involve read and write operations for weight updates during backpropagation. However, on-device training on microcontroller units (MCUs) presents two challenges. First, the on-chip SRAM has insufficient capacity to store the weight. Second, the large flash memory, which has a constraint on write access, becomes necessary to accommodate the network for on-device training on MCUs. To tackle these memory constraints, we propose a partial weight update technique based on gradient delta computation. The weights are stored in flash memory, and a part of the weight to be updated is selectively copied to the SRAM from the flash memory. We implemented this approach for training a fully connected network on an on-device MNIST digit classification task using only 20-kB SRAM and 1912-kB flash memory on an MCU. The proposed technique achieves reasonable accuracy with only 18.52% partial weight updates, which is comparable to state-of-the-art results. Furthermore, we achieved a reduction of up to 46.9% in the area-power-delay product compared to a commercially available high-performance MCU capable of embedding the entire model parameter, taking into account the area scale factor. | Kwon, Jisu; Park, Daejin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 57215531728; 55463943600 | boltanut@knu.ac.kr; | IEEE EMBEDDED SYSTEMS LETTERS | IEEE EMBED SYST LETT | 1943-0663 | 1943-0671 | 15 | 4 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, SOFTWARE ENGINEERING | 2023 | 1.7 | 54.9 | 0 | 2025-06-25 | 0 | 0 | Artificial neural networks; embedded software; flash memories; microcontrollers | Artificial neural networks; embedded software; flash memories; microcontrollers | Application specific integrated circuits; Flash memory; Microcontrollers; Programmable logic controllers; Static random access storage; Embedded microcontroller; Memory-management; Microcontroller unit; Random access memory; Read operation; Runtimes; Systems-on-Chip; Training procedures; Weight update; Write operations; System-on-chip | English | 2023 | 2023-12 | 10.1109/les.2023.3298731 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Ecological Optics as the Conceptual Basis for the Interpersonal Self and Social Interaction | Agency, the ability to negotiate one's surroundings to bring about changes, is the defining feature of animacy. Because agency is embodied in each individual's self, inquiry into agency is necessarily an inquiry into selfhood. William James divided selfhood into the self as "I" and the self as "me" with the I self being, in essence, an active agent responsible for thoughts and actions. In Gibson's ecological paradigm, self plays a central role, being co-perceived with the environment. Neisser (1988), an advocate of Gibson, classified self via 5 different forms of self-knowledge, each portraying a different aspect of self. Of these, the ecological self is an agent that regulates its encounters with the surroundings based on affordances the environment offers, whereas the interpersonal self is an agent that interacts with conspecifics based on the mutual affordances their interactions offer. For interpersonal selves to interact effectively with each other necessitates that their shared environment becomes common knowledge to all participants, based on information determined in accordance with the principle of ecological optics (in particular, information about occluding edges, reversible occlusion, and opaque and non-opaque substances). We suggest that Gibson's principles of ecological optics be extended to the social domain, as he envisioned. | Kim, Nam-Gyoon; Effken, Judith A.; Lee, Ho-Won | Keimyung Univ, Dept Psychol, 1095 Dalgubeol Daero, Daegu 42601, South Korea; Univ Arizona, Coll Nursing, Tucson, AZ USA; Kyungpook Natl Univ, Brain Sci & Engn Inst, Sch Med, Dept Neurol, Seoul, South Korea | 7403396492; 6603872209; 35337240700 | nk70@kmu.ac.kr; | ECOLOGICAL PSYCHOLOGY | ECOL PSYCHOL | 1040-7413 | 1532-6969 | 35 | 3 | SSCI | PSYCHOLOGY, EXPERIMENTAL | 2023 | 1.8 | 55.1 | 0 | 2025-06-25 | 0 | 0 | INFORMATION; AFFORDANCES; PSYCHOLOGY; MOTIVATION; PERCEPTION; LANGUAGE; DYNAMICS; KNOWLEDGE; OCCLUSION; AUTISM | English | 2023 | 2023-07-03 | 10.1080/10407413.2023.2193173 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Chitinase 3-like 1 induces cancer cell migration in solitary fibrous tumors | Solitary fibrous tumor (SFT) is a rare mesenchymal tumor that is diagnosed through the detection of the NAB2-STAT6 fusion gene. SFT rarely progresses to malignant tumors; however, metastasis is exhibited in approximately 20% of patients with SFT. In this study, we found that chitinase 3-like 1 (CHI3L1), which induces cancer cell migration, was upregulated in NIH-3T3 cells that were transfected with the NAB2-STAT6 fusion gene. Moreover, the expression levels of the migration markers MMP2 and MMP9 were increased and the p-Akt level was also upregulated. In addition, it was observed that when CHI3L1 siRNA was transfected into NAB2-STAT6-transfected cells, cell migration and proliferation were reduced. Therefore, this study demonstrated that CHI3L1 activates Akt signaling to induce cell migration.(c) 2023 Elsevier Inc.

| ○ | ○ | Article | Methyl jasmonate-induced senescence results in alterations in the status of chlorophyll precursors and enzymatic antioxidants in rice plants | We examined the control of chlorophyll biosynthesis and protective mechanisms during leaf senescence induced by methyl jasmonate (MeJA). After MeJA treatment, rice plants displayed evidence of great oxidative stress regarding senescence symptoms, disruption of membrane integrity, H2O2 production, and decreased chlorophyll content and photosynthetic efficiency. After 6 h of MeJA treatment, plants greatly decreased not only their levels of chlorophyll precursors, including protoporphyrin IX (Proto IX), Mg-Proto IX, Mg-Proto IX methylester, and protochlorophyllide, but also the expression levels of the chlorophyll biosynthetic genes CHLD, CHLH, CHLI, and PORB, with the greatest decreases at 78 h. MeJA-treated plants showed a noticeable degradation of light-harvesting chlorophyll-binding proteins (LHCB) at 78 h after MeJA treatment but began to downregulate expression of LHCB at 6 h. Photoprotection, as indicated by nonphotochemical quenching, slightly increased only at 6 h after MeJA treatment. In parallel to the increased activities of superoxide dismutase, catalase (CAT), ascorbate peroxidase (APX), and peroxidase, MeJA-treated plants responded to senescence by markedly upregulating the expression of APX and CAT. Our study demonstrates that rice plants developed protective mechanisms for mitigating oxidative stress by scavenging phototoxic chlorophyll precursors and activating enzymatic antioxidant responses during MeJA-induced senescence.& COPY; 2023 Elsevier Inc.

| ○ | ○ | Article | Optimizing and determining the click chemistry mediated Cu-64 radiolabeling and physiochemical characteristics of trastuzumab conjugates | Over the last decade, Cu-64-labeling of monoclonal antibody (mAb) via inverse electron demand DielsAlder click chemistry (IEDDA) have received much attention. Despite the tetrazine-transcyclooctene (Tz-TCO) click chemistry's convenience and efficiency in mAb labeling, there is limited information about the ideal parameters in the development of click chemistry mediated (radio)immunoconjugates. This encourages us to conduct a systematic optimization while concurrently determining the physiochemical characteristics of the model mAb, trastuzumab, and TCO conjugates. To accomplish this, we investigated a few critical parameters, first, we determined the degree of conjugations with varying molar equivalents (eq.) of TCO (3, 5, 10, and 15 eq.). Through analytical techniques like size exclusion chromatography, dynamic light scattering, and zeta potential, qualitative analysis were performed to determine the purity, degree of aggregation and net charge of the conjugates. We found that as the degree of conjugation increased the purity of intact mAb fraction is compromised and net charge of conjugates became less positive. Next, all trastuzumab-PEG(4)-TCO conjugates with varying molar ratio and quantity (30, 50, 100, 200, 250 mg) were radiolabeled with Cu-64-NOTA-PEG(4)-Tz via IEDDA click chemistry and radiochemical yields were determined by radio-thin layer chromatography. The radiochemical yields of trastuzumab conjugates improved with increased amount and molar ratio. Next, we investigated the effect of the radioprotectant ascorbic acid (AA) of varied concentrations (0.25, 0.5, 0.75, 1 mM) on radiochemical yields and subsequent pharmacokinetics. A concentration of 0.25 mM of AA was found to be optimal for click reaction and in vivo biodistribution. Finally, we investigated the indirect influence of bioconjugation buffers on radiochemical yields and biodistribution in NIH3T6.7 tumor models that resulted approximately similar to 11 %ID/g tumor uptake.
