| ○ | ○ | Article | Commuting Jacobi Operators on Real Hypersurfaces of Type B in the Complex Quadric | In this paper, first, we investigate the commuting property between the normal Jacobi operator (R) over bar (N) and the structure Jacobi operator R-xi for Hopf real hypersurfaces in the complex quadric Q(m) = SOm+2/SOmSO2 for m >= 3, which is defined by (R) over bar R-N(xi) = R-xi(R) over bar (N). Moreover, a new characterization of Hopf real hypersurfaces with U-principal singular normal vector field in the complex quadric Q(m) is obtained. By virtue of this result, we can give a remarkable classification of Hopf real hypersurfaces in the complex quadric Q(m) with commuting Jacobi operators. | Lee, Hyunjin; Suh, Young Jin | Kyungpook Natl Univ, Res Inst Real & Complex Manifolds RIRCM, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, RIRCM, Daegu 41566, South Korea | 55706812200; 7202260479 | lhjibis@hanmail.net;yjsuh@knu.ac.kr; | MATHEMATICAL PHYSICS ANALYSIS AND GEOMETRY | MATH PHYS ANAL GEOM | 1385-0172 | 1572-9656 | 23 | 4 | SCIE | MATHEMATICS, APPLIED;PHYSICS, MATHEMATICAL | 2020 | 0.933 | 75.3 | 2.35 | 2025-06-25 | 22 | 21 | Commuting Jacobi operator; A-isotropic; A-principal; Kahler structure; Complex conjugation; Complex quadric | TOTALLY GEODESIC SUBMANIFOLDS; EINSTEIN HYPERSURFACES; CONTACT HYPERSURFACES | A-isotropic; A-principal; Commuting Jacobi operator; Complex conjugation; Complex quadric; Kähler structure | English | 2020 | 2020-12 | 10.1007/s11040-020-09370-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Strength Evaluation of Angle Type Shear Connectors in Composite Beams | Composite structures are used in structural systems to take advantage of concrete and steel, and the role of shear connectors between the two is extremely important. Currently, anchor- and angle-type connectors are mainly used as shear connectors, and the angle type offers several advantages over the anchor type. The angle type can be manufactured as a shape that fits the composite structure with a greater basic strength than that of the anchor type, so it can be installed in wider spaces. Much research has been conducted on the anchor type, but that on the angle type has been insufficient so far. In this study, push-out and yield-strength tests were conducted on various angle-type shear connectors used for filling-type composite beams. The variables included the height, width, and thickness of the angle-type shear connector. The tests were terminated when a strength reduction of 80% of the maximum strength occurred. The slip capacity of the specimen was evaluated by referring to Eurocode. Based on the experimental results, the design equations have been reviewed to determine whether or not they can be used for the shear connection of concrete-filled composite beams. In addition, the strength was assessed by existing design equations. Meanwhile, a new design equation was proposed, including the height of the shear connector, which is not considered in the current design equations. The other strength was calculated by the new design equation. | Lee, Jun-Seop; Shin, Kyung-Jae; Lee, Hee-Du; Woo, Jong-Hun | Kyungpook Natl Univ, 80 Daehak Ro, Daegu 41566, South Korea | 57221623386; 14039501000; 53865180300; 57210344487 | shin@knu.ac.kr; | INTERNATIONAL JOURNAL OF STEEL STRUCTURES | INT J STEEL STRUCT | 1598-2351 | 2093-6311 | 20 | 6 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2020 | 1.35 | 75.4 | 0.3 | 2025-06-25 | 6 | 8 | Composite beam; Shear connector; Angle-type connector; Shear strength | PUSH-OUT TESTS; BEHAVIOR | Angle-type connector; Composite beam; Shear connector; Shear strength | Composite beams and girders; Concrete beams and girders; Shear flow; Structure (composition); Concrete-filled; Design equation; Maximum strength; Shear connections; Shear connector; Strength evaluation; Strength reduction; Structural systems; Composite structures | English | 2020 | 2020-12 | 10.1007/s13296-020-00433-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Association between institutional case volume and mortality following thoracic aorta replacement: a nationwide Korean cohort study | BackgroundThe inverse relationship between case volume and postoperative mortality following high-risk surgical procedures have been reported. Thoracic aorta surgery is associated with one of the highest postoperative mortality. The relationship between institutional case volume and postoperative mortality in patients undergoing thoracic aorta replacement surgery was evaluated.MethodsAll thoracic aorta replacement surgeries performed in Korea between 2009 and 2016 in adult patients were analyzed using an administrative database. Hospitals were divided into low (60 cases/year) volume centers depending on the annual average number of thoracic aorta replacement surgeries performed. The impact of case volume on in-hospital mortality was assessed using the logistic regression.ResultsAcross 83 hospitals, 4867 cases of thoracic aorta replacement were performed. In-hospital mortality was 8.6% (191/2222), 10.7% (77/717), and 21.9% (422/1928) in high, medium, and low volume centers, respectively. The adjusted risk of in-hospital mortality was significantly higher in medium (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.16-2.11, P=0.004) and low volume centers (OR, 3.12; 95% CI, 2.54-3.85, P<0.001) compared to high volume centers.ConclusionsPatients who had underwent thoracic aorta replacement surgery in lower volume centers had increased risk of in-hospital mortality after surgery compared to those in higher volume centers. Our results may provide the basis for minimum case volume requirement or regionalization in thoracic aorta replacement surgery for optimal patient outcome. | Nam, Karam; Jang, Eun Jin; Jo, Jun Woo; Choi, Jae Woong; Lee, Minkyoo; Ryu, Ho Geol | Seoul Natl Univ, Seoul Natl Univ Hosp, Dept Anesthesiol & Pain Med, Coll Med, 101 Daehak Ro, Seoul 03080, South Korea; Andong Natl Univ, Dept Informat Stat, Andong, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Dept Thorac & Cardiovasc Surg, Coll Med, Seoul, South Korea | Ryu, Ho/J-5463-2012 | 55750745300; 37861741600; 57210425017; 58120781500; 57217588963; 7202277246 | hogeol@gmail.com; | JOURNAL OF CARDIOTHORACIC SURGERY | J CARDIOTHORAC SURG | 1749-8090 | 15 | 1 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS;SURGERY | 2020 | 1.637 | 75.6 | 0.3 | 2025-06-25 | 5 | 4 | Case volume; Surgical prognosis; Thoracic aorta replacement; Volume-outcome relationship | OPERATIVE MORTALITY; HOSPITAL VOLUME; SURGEON VOLUME; PROCEDURAL VOLUME; INTENSIVE-CARE; OUTCOMES; REGIONALIZATION; REPAIR | Case volume; Surgical prognosis; Thoracic aorta replacement; Volume-outcome relationship | Aged; Aorta, Thoracic; Cardiac Surgical Procedures; Female; Hospital Mortality; Hospitals, High-Volume; Hospitals, University; Humans; Logistic Models; Male; Middle Aged; Odds Ratio; Republic of Korea; Retrospective Studies; Risk Factors; Treatment Outcome; adult; article; cohort analysis; controlled study; female; hospital mortality; human; Korea; Korean (people); major clinical study; male; multicenter study; prognosis; regionalization; surgical mortality; thoracic aortic surgery; aged; heart surgery; high volume hospital; middle aged; mortality; odds ratio; retrospective study; risk factor; South Korea; statistical model; surgery; thoracic aorta; treatment outcome; university hospital | English | 2020 | 2020-06-29 | 10.1186/s13019-020-01204-0 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Half-turned truncal switch operation after single ventricle palliation in a patient with borderline left heart hypoplasia | BackgroundThe optimal surgical strategy for the correction of double outlet right ventricle (DORV, transposition of the great arteries [TGA] type) or TGA with ventricular septal defect (VSD), pulmonary stenosis (PS), and borderline small left ventricle (LV) is still controversial. The half-turned truncal switch operation (HTTSO) introduced by Yamagishi and colleagues is a good option, but it is still challenging in a patient with borderline small LV. We aimed to describe our experience of a case of HTTSO conversion from single ventricle palliation.Case presentationA 5-year-old girl with single ventricle physiology was referred to our hospital from Kazakhstan for a Fontan operation. At the time of birth, she was diagnosed with DORV (TGA type), PS, and situs inversus totalis, with moderate valvar and subvalvar stenosis and a relatively small LV cavity. Her LV volume was not adequate to support the systemic circulation; therefore, doctors in Kazakhstan selected the single ventricle palliation course of treatment for the infant. At 4months of age, she underwent left-sided modified Blalock-Taussig shunt, patent ductus arteriosus ligation, and atrial septectomy. At 2years of age, shunt takedown, left bidirectional cavopulmonary shunt, and main pulmonary artery division were performed. Annual echocardiography of the patient showed that the LV size was growing too adequately to persist with the single ventricle palliation course of treatment. Via a multidisciplinary approach, we considered her LV to be suitable for biventricular repair and HTTSO was planned. The operation and postoperative course were uneventful. The patient was discharged on postoperative day 6 and went back to Kazakhstan.ConclusionsBased on our successful surgical outcome, in patients diagnosed with DORV (TGA type) or TGA with VSD, PS, and borderline LV, HTTSO after achieving adequate LV growth by single ventricle palliation may be considered a good alternative to conventional operations in patients at a high risk for initial biventricular repair. | Oh, Tak-Hyuk; Jung, Hanna; Cho, Joon Yong; Lee, Youngok | Kyungpook Natl Univ, Sch Med, Dept Thorac & Cardiovasc Surg, Kyungpook Natl Univ Hosp, 130 Dongdeok Ro, Daegu 41944, South Korea | Jung, Hanna/Y-4165-2019 | 56467700700; 56467570700; 57195637434; 36461117600 | yolee1210@knu.ac.kr; | JOURNAL OF CARDIOTHORACIC SURGERY | J CARDIOTHORAC SURG | 1749-8090 | 15 | 1 | SCIE | CARDIAC & CARDIOVASCULAR SYSTEMS;SURGERY | 2020 | 1.637 | 75.6 | 0 | 2025-06-25 | 0 | 0 | Biventricular repair; Half-turned truncal switch operation; Left heart hypoplasia; Single ventricle palliation; Transposition of great arteries | CAVOPULMONARY SHUNT; GREAT-ARTERIES; SEPTAL-DEFECT; TRANSPOSITION; CONVERSION; REPAIR | Biventricular repair; Half-turned truncal switch operation; Left heart hypoplasia; Single ventricle palliation; Transposition of great arteries | Cardiovascular Abnormalities; Child, Preschool; Dextrocardia; Double Outlet Right Ventricle; Echocardiography; Female; Fontan Procedure; Heart Septal Defects, Ventricular; Heart Ventricles; Humans; Hypoplastic Left Heart Syndrome; Palliative Care; Pulmonary Valve Stenosis; Tomography, X-Ray Computed; Transposition of Great Vessels; Treatment Outcome; cardiovascular malformation; case report; dextrocardia; echocardiography; female; Fontan procedure; great vessels transposition; heart right ventricle double outlet; heart septum defect; heart ventricle; human; hypoplastic left heart syndrome; palliative therapy; preschool child; pulmonary valve stenosis; treatment outcome; x-ray computed tomography | English | 2020 | 2020-10-09 | 10.1186/s13019-020-01357-y | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Correlation of thermal conductivity with the catalytic activity of nanoparticles: the oxidation of benzyl alcohol | Different nanoparticles like cobalt oxide (Co3O4), iron oxide (Fe3O4), manganese ferrite (MnFe2O4), gadolinium oxide (Gd2O3), cerium oxide (CeO2), iron-cobalt (FeCo) and iron-cerium (FeCe) were prepared and tested for their catalytic activity in the liquid phase oxidation of benzyl alcohol (BzOH) to benzaldehyde (BzH) in a self-designed Pyrex glass Gas Blowing Rotating Reactor (GBR reactor). Textural properties such as size and shape of catalysts were studied through available characterization techniques for better understanding of their catalytic activity. The oxidation of BzOH was carried out in different solvents such as water, toluene, benzene and heptane to unveil the effect of thermal conductivity of solvent on the catalytic activity of nanoparticles. The reaction was also carried out in solvent-free conditions in the presence of O-2. The efficiency of each catalyst was measured in term of productivity (mmol g(-1) h(-1)) instead of conventional units. The productivity values in comparison to available reports revealed that these catalysts will be prospective alternative to conventional industrial catalysts. | Sadiq, Saima; Sadiq, Muhammad; Saeed, Khalid; Rehman, Najeeb Ur; Ali, Qaisar | Univ Malakand, Dept Chem, Chakdara 18800, Pakistan; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Bacha Khan Univ, Dept Chem, Charsadda 24420, Pakistan | Sadiq, Saima/JAN-6421-2023; Sadiq, Muhammad/HMP-3877-2023; Rehman, Najeeb Ur/GZN-1854-2022; Saeed, Khalid/MVZ-2063-2025 | 59029170800; 14627798100; 56875271500; 57881654400; 59431264000 | sadiq@uom.edu.pk; | REACTION KINETICS MECHANISMS AND CATALYSIS | REACT KINET MECH CAT | 1878-5190 | 1878-5204 | 130 | 1 | SCIE | CHEMISTRY, PHYSICAL | 2020 | 2.081 | 76.2 | 0.36 | 2025-06-25 | 7 | 7 | Nanoparticles; Oxidation; Liquid phase; Benzyl alcohol | SELECTIVE AEROBIC OXIDATION; LIQUID-PHASE OXIDATION; OXIDE NANOPARTICLES; COMPLEX; BENZALDEHYDE; GREEN; ALDEHYDES; EFFICIENT; SILICA; HYDROGENATION | Benzyl alcohol; Liquid phase; Nanoparticles; Oxidation | Binary alloys; Catalytic oxidation; Cerium alloys; Cerium oxide; Cobalt alloys; Cobalt compounds; Gadolinium compounds; Iron alloys; Iron oxides; Magnetite; Nanoparticles; Organic solvents; Oxidation; Productivity; Thermal conductivity; Characterization techniques; Different solvents; Gadolinium oxide; Industrial catalyst; Liquid-phase oxidation; Manganese ferrites; Solvent free conditions; Textural properties; Catalyst activity | English | 2020 | 2020-06 | 10.1007/s11144-020-01784-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | An advanced loop-mediated isothermal amplification assay for the rapid detection of beak and feather disease virus in psittacine birds | Swarm primer-applied loop-mediated isothermal amplification (sLAMP) assay was developed for the rapid and specific detection of the ORF V1 gene of beak and feather disease virus (BFDV). The amplification can be completed in 40 min at 62 degrees C, and the results can be visually detected by the naked eye. The assay specifically amplified BFDV DNA and not amplified other viral nucleic acids. The limit of detection of the assay was 5 x 10(2) DNA copies/reaction, which was lower than that of the previously described LAMP (preLAMP) assay and comparable to that of a previously reported real time quantitative PCR (qPCR) assay. The detection rates of BFDV from psittacine clinical samples by the sLAMP, qPCR and preLAMP assays were 36.0 %, 36.0 % and 25.6 %, respectively, and the sLAMP results showed 100.0 % concordance with the qPCR results with a kappa value of 1.0. On the other hand, the preLAMP assay did not detect nine out of the 31 samples that were positive by sLAMP and qPCR assays, probably due to low sensitivity of the assay. These data suggest that the newly developed sLAMP assay will be a valuable tool for the rapid, sensitive, specific and reliable detection of BFDV in suspected psittacine birds, even in resource-limited laboratories. | Chae, Ha-Gyeong; Lim, Da-Rae; Kim, Hye-Ryung; Park, Min-Ji; Park, Choi-Kyu | Kyungpook Natl Univ, Coll Vet Med, 80 Daehakro, Daegu 41566, South Korea; Kyungpook Natl Univ, Anim Dis Intervent Ctr, 80 Daehakro, Daegu 41566, South Korea; Anim & Plant Quarantine Agcy, Avian Influenza Res & Diagnost Div, Gimcheon 39660, Gyeongsangbuk D, South Korea | 57202787553; 57195776777; 57195772612; 57202785813; 24768064900 | parkck@knu.ac.kr; | JOURNAL OF VIROLOGICAL METHODS | J VIROL METHODS | 0166-0934 | 1879-0984 | 277 | SCIE | BIOCHEMICAL RESEARCH METHODS;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;VIROLOGY | 2020 | 2.014 | 76.3 | 0.15 | 2025-06-25 | 4 | 5 | Psittacine bird; Beak and feather disease virus; Loop-mediated isothermal amplification; Swarm primers | POLYMERASE-CHAIN-REACTION; DIAGNOSIS; PCR; INFECTIONS; LAMP | Beak and feather disease virus; Loop-mediated isothermal amplification; Psittacine bird; Swarm primers | Animals; Bird Diseases; Circoviridae Infections; Circovirus; DNA Primers; Molecular Diagnostic Techniques; Nucleic Acid Amplification Techniques; Parrots; Sensitivity and Specificity; virus DNA; primer DNA; animal tissue; Article; beak and feather disease; Beak and feather disease virus; controlled study; diagnostic test accuracy study; gene amplification; gene dosage; intermethod comparison; limit of detection; loop mediated isothermal amplification; nonhuman; ORF V1 gene; priority journal; psittacine; real time polymerase chain reaction; sensitivity and specificity; swarm primer applied loop mediated isothermal amplification; virus detection; virus gene; animal; bird disease; Circoviridae infection; Circovirus; genetics; isolation and purification; molecular diagnosis; nucleic acid amplification; parrot; procedures; veterinary medicine; virology | English | 2020 | 2020-03 | 10.1016/j.jviromet.2020.113819 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The N=4 coset model and the higher spin algebra | By computing the operator product expansions between the first two N = 4 higher spin multiplets in the unitary coset model, the (anti-)commutators of higher spin currents are obtained under the large (N; k) 't Hooft-like limit. The free field realization with complex bosons and fermions is presented. The (anti-)commutators for generic spins s(1) and s(2) with manifest SO(4) symmetry at vanishing 't Hooft-like coupling constant are completely determined. The structure constants can be written in terms of the ones in the N = 2 W-infinity algebra found by Bergshoeff, Pope, Romans, Sezgin and Shen previously, in addition to the spin-dependent fractional coefficients and two SO(4) invariant tensors. We also describe the N = 4 higher spin generators, by using the above coset construction results, for general superspin s in terms of oscillators in the matrix generalization of AdS(3) Vasiliev higher spin theory at nonzero 't Hooft-like coupling constant. We obtain the N = 4 higher spin algebra for low spins and present how to determine the structure constants, which depend on the higher spin algebra parameter, in general, for fixed spins s(1) and s(2) | Ahn, Changhyun; Kim, Dong-gyu; Kim, Man Hea | Kyungpook Natl Univ, Dept Phys, Taegu 41566, South Korea; Swiss Fed Inst Technol, Inst Theoret Phys, CH-8093 Zurich, Switzerland | KIM, MAN HEA/GNN-0026-2022 | 7201986707; 57195309200; 57190220753 | ahn@knu.ac.kr;ehdrb430@knu.ac.kr;manhea@knu.ac.kr; | INTERNATIONAL JOURNAL OF MODERN PHYSICS A | INT J MOD PHYS A | 0217-751X | 1793-656X | 35 | 11-12 | SCIE | PHYSICS, NUCLEAR;PHYSICS, PARTICLES & FIELDS | 2020 | 1.381 | 76.3 | 0.61 | 2025-06-25 | 9 | 9 | AdS/CFT; higher spin theory; W symmetry; coset model | W-INFINITY; UNITARY REPRESENTATIONS; STRUCTURE CONSTANTS; QUANTIZATION; SPHERE | AdS/CFT; coset model; higher spin theory; W symmetry | English | 2020 | 2020-04-30 | 10.1142/s0217751x20500463 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Physiological influence of tylosin tartrate overdose in vivo in rats | The aim of this study was to evaluate the physiological effects of tylosin in rats. Tylosin was administered orally to pubertal male and female rats at concentrations of 0.005, 0.2, 10 and 200 mg/kg b.w. for 6 weeks. The overall body and organ weights were recorded. Serum levels of immunoglobulins, haematological values, histopathological lesions in different organs, and gene expression profiles in pituitary glands were investigated. The mean platelet volume was increased, and the monocyte count was decreased significantly in both male and female rats treated with tylosin. Compared to the untreated control, alanine transaminase in both types of rats and total serum bilirubin in female rats were increased significantly with the administration of tylosin (200 mg/kg), however, lactate dehydrogenase in female rats was decreased. The levels of immunoglobulin M were reduced in both male and female rats but immunoglobulin G levels were significantly reduced only in female rats which were treated with tylosin. Cell proliferation- and adhesion-associated genes were expressed more but apoptosis gene expressions were decreased in the pituitary gland of tylosin-treated rats. In conclusion, this study revealed that the use of tylosin at therapeutic dosage is possibly not completely safe. | Kang, JeongWoo; Hossain, Md Akil; Park, Hae-chul; Kim, Tae-wan; Jeong, Sang-Hee | Anim & Plant Quarantine Agcy APQA, Vet Drugs & Biol Div, Gimcheon Si, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Physiol, Daegu, South Korea; Hoseo Univ, Coll Nat Sci, GLP Res Ctr, Asan, South Korea | Hossain, Akil/AAY-7229-2020 | 57212201397; 55754133800; 57210463034; 57202769925; 26643442200 | hijach@korea.kr; | ACTA VETERINARIA BRNO | ACTA VET BRNO | 0001-7213 | 1801-7576 | 89 | 3 | SCIE | VETERINARY SCIENCES | 2020 | 0.667 | 76.4 | 0.37 | 2025-06-25 | 2 | 2 | Immunoglobulins; histopathology; physiology; toxicity; tylosin | 6-WEEK ORAL TOXICITY; IMMUNE-RESPONSES; EXPRESSION | Histopathology; Immunoglobulins; Physiology; Toxicity; Tylosin | alanine aminotransferase; aspartate aminotransferase; ccnb1; cholesterol; cntn6; glucose; high density lipoprotein; immunoglobulin E; immunoglobulin G; immunoglobulin M; lactate dehydrogenase; low density lipoprotein; mgst2; Myc protein; peptides and proteins; pkt2; slc12a2; triacylglycerol; tylosin; tylosin tartrate; unclassified drug; animal experiment; animal model; animal tissue; Article; bilirubin blood level; biochemical analysis; DNA microarray; enzyme linked immunosorbent assay; eosinophil percentage; female; gene expression; hematological parameters; histopathology; immunofluorescence assay; intoxication; leukocyte count; lymphocyte percentage; male; mean corpuscular hemoglobin; mean corpuscular volume; mean platelet volume; monocyte percentage; neutrophil percentage; nonhuman; rat; RNA extraction; urea nitrogen blood level | English | 2020 | 2020 | 10.2754/avb202089030283 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Rogue Device Mitigation in the Internet of Things: A Blockchain-Based Access Control Approach | Recent technological developments in wireless and sensor networks have led to a paradigm shift in interacting with everyday objects, which nurtured the concept of Internet of Things (IoT). However, low-powered nature of IoT devices generally becomes a hindrance that makes them vulnerable to a wide array of attacks. Among these, the emergence of rogue devices is quickly becoming a major security concern. Rogue devices are malicious in nature which typically execute different kinds of cyberattacks by exploiting the weaknesses of access control schemes in IoT environments. Therefore, access control is one of the crucial aspects of an IoT ecosystem that defines an entry point for a device or a user in the network. This paper investigates this issue and presents an access control scheme by integrating an IoT network with blockchain technology, thereby arguing to replace the traditional centralized IoT-server architecture with a decentralized one. The blockchain is used with smart contracts to establish a secure platform for device registration. Due to this reason, the IoT devices are first required to register themselves and access the network via contracts thereafter. Moreover, the contracts host a device registry, the access control list, to grant or deny access to devices. This allows the proposed scheme to authorize registered devices only and block unregistered ones, which facilitates the mitigation of rogue devices. To demonstrate the feasibility and improvements of the proposed scheme, security analysis along with in-depth performance evaluation are conducted, where the obtained results indicate its applicability. A case study is also formulated with a comparative analysis that confirms the superior performance of the proposed scheme for low-powered IoT systems. | Javaid, Uzair; Jameel, Furqan; Javaid, Umair; Khan, Muhammad Toaha Raza; Jantti, Riku | Natl Univ Singapore, Dept Elect & Comp Engn, 4 Engn Dr 3, Singapore 117583, Singapore; Aalto Univ, Dept Commun & Networking, Espoo 02150, Finland; IREC MIRO, Ave Hippocrate 54, B-1200 Brussels, Belgium; ICTEAM UCLouvain, Ave Hippocrate 54, B-1200 Brussels, Belgium; Kyungpook Natl Univ, Daegu 41566, South Korea | Jäntti, Riku/G-2270-2013; Khan, Turyalai/HPH-0061-2023; Javaid, Uzair/AAA-5316-2019 | 57216811863; 57193333654; 57208975610; 57202044597; 56186204500 | furqan.jameel@aalto.fi; | MOBILE INFORMATION SYSTEMS | MOB INF SYST | 1574-017X | 1875-905X | 2020 | SCIE | COMPUTER SCIENCE, INFORMATION SYSTEMS;TELECOMMUNICATIONS | 2020 | 1.802 | 76.4 | 0.06 | 2025-06-25 | 1 | 2 | AUTHENTICATION PROTOCOL; PRIVACY | Access control; Blockchain; Wireless sensor networks; Access control lists; Access control schemes; Comparative analysis; Internet of Things (IOT); Security analysis; Server architecture; Technological development; Wireless and sensor networks; Internet of things | English | 2020 | 2020-10-28 | 10.1155/2020/8831976 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Correlation between concept comprehension and mental semantic networks for scientific terms | Background We adopted a theoretical framework that the acquisition of a scientific concept comprises the development of connections among conceptual elements associated with a scientific term within a mental semantic network. Given this framework, the hypothesis that the surrounding words connected with a scientific term are relevant to the comprehension of that concept was considered. Purpose Students' mental semantic networks through a word association test were examined, which experimentally revealed whether the quantitative and qualitative connection of scientific terminology with conceptual elements is related to concept comprehension. Sample We selected five scientific concept words - 'force', 'motion', 'speed', 'mass' and 'gravity' - and investigated the mental semantic networks of 1,189 students regarding these five words. Design and Methods We prepared a word association test and a concept comprehension test for the 5 words; further, we asked the subjects to write 10 words that are associated with each stimulus word. The concept comprehension test was conducted with multiple-choice questions, comprising 6 questions for each stimulus word. Additionally, this study examined the relation between the concept comprehension and word association test scores. Results All the values extracted from the word association test were significantly correlated with concept comprehension. Specifically, the concept comprehension score was higher when the relation between the scientific terminology and words that form the scientific context as well as the scientific terminology and other scientific terminologies were more closely and frequently connected in the mental semantic network. Conclusion This study experimentally verifies that word-level connections are related to concept comprehension in students' mental semantic networks. This shows that a cognitive linguistic approach to the development and modification of students' mental semantic networks can be applied effectively in science education. Moreover, it indicates the possibility of adopting linguistic strategies in science education for the formation and modification of scientific concepts. | Yun, Eunjeong | Kyungpook Natl Univ, Daegu 41566, South Korea | Yun, Eunjeong/HTT-0809-2023 | 57023394700 | ejyun@knu.ac.kr; | RESEARCH IN SCIENCE & TECHNOLOGICAL EDUCATION | RES SCI TECHNOL EDUC | 0263-5143 | 1470-1138 | 38 | 3 | SSCI | EDUCATION & EDUCATIONAL RESEARCH | 2020 | 1.54 | 76.8 | 0.39 | 2025-06-25 | 1 | 3 | Scientific terminology; concept comprehension; mental semantic network; word association test | WORD-ASSOCIATION TESTS; COGNITIVE STRUCTURE; LANGUAGE; EQUILIBRIUM; MECHANICS; TEACHERS | concept comprehension; mental semantic network; Scientific terminology; word association test | English | 2020 | 2020-07-02 | 10.1080/02635143.2020.1777095 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of a Novel Plastic Hardening Model Based on Random Tree Growth Method | The flow functions for plastic deformation have been developed to describe the plastic behavior of sheet metals. In order to explain the plastic behavior of material in metal forming processes via finite element analyses, two basic input functions should be applied. One is the yield function that determines the yielding behavior. The other is flow function to describe the hardening property of sheet metal. To describe the hardening properties of sheet materials under quasi-static tension condition in a wide range of plastic straining, various different equations are known such as classical Swift, Voce, Holloman, combined Swift-Voce, and recently proposed Kim-Tuan equations, etc. Those hardening equations are based on metallurgical or phenomenological investigations, and however the application of each equation has some limitation. In this study, the random growth of the binary tree method is introduced to develop the reliable hardening equations of various sheet metals (i.e. DP980, Pure Ti, AA5052-O, STS304, Ti-Gr2, and Mg-AZ31B) with no knowledge of existing hardening equation types. To evaluate the proposed method, the proposed equations developed by new approach are compared with the Voce, Swift, and Kim-Tuan hardening equations for stress-strain curve and the plastic instability point. Consequently, the proposed approach was proven to be very efficient to find the reliable and accurate hardening equation for any kind of materials. | Son, Hyoung-Seo; Kim, Young-Gon; Kim, Jin-Jae; Kim, Young-Suk | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Grad Sch Mech Engn, Daegu 41566, South Korea | Kim, Sang-Hoon/AAA-2248-2020 | 57220604373; 55699478000; 57209555877; 36065820800 | caekim@knu.ac.kr; | KOREAN JOURNAL OF METALS AND MATERIALS | KOREAN J MET MATER | 1738-8228 | 58 | 11 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2020 | 1.005 | 76.9 | 0 | 2025-06-25 | 0 | 0 | random growth; binary tree; hardening function; curve fitting; maximum tensile force point | PREDICTION; IDENTIFICATION; ANISOTROPY | Binary tree; Curve fitting; Hardening function; Maximum tensile force point; Random growth | Binary trees; Hardening; Metal forming; Metals; Plastic deformation; Strain; Stress-strain curves; Hardening properties; Input functions; Metal-forming process; Plastic behavior; Plastic hardening; Plastic instabilities; Plastic straining; Yielding behavior; Sheet metal | Korean | 2020 | 2020-11 | 10.3365/kjmm.2020.58.11.741 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Electrolyte Anion on Electrochemical Behavior of Nickel Hexacyanoferrate Electrode in Aqueous Sodium-Ion Batteries | Nickel hexacyanoferrate (NiHCF) has a three-dimensional open framework structure, excellent long-cycling stability and rate performance as a cathode for aqueous sodium-ion batteries. However, the specific capacity of NiHCF is lower than that of present cathodes for aqueous batteries. A sodium-ion electrolyte was explored to achieve optimum capacity with NiHCF. Powder-type NiHCF was fabricated by coprecipitation with the atomic composition K0.065Ni1.44Fe(CN)(6)center dot 4.4H(2)O. The presence of Fe vacancies in the atomic composition is attributable to the inclusion of coordinating and zeolitic water during coprecipitation. Two sodium-ion electrolytes, 1 M Na2SO4 and 1 M NaNO3, were employed to analyze the electrochemical behavior of the NiHCF electrode. Identical redox potentials to 0.58 V (vs. NHE) were measured in both electrolytes. However, a lower overpotential was observed in NaNO3 compared to Na2SO4 as a result of the smaller interfacial charge transfer resistance. The lower charge transfer resistance in the NaNO3 solution produced a higher specific capacity of 57 mAh g(-1) (1 C-rate) and the superior capacity retention of 46.6% at 20 C-rate. The anion in the aqueous electrolyte changed the charge transfer resistance at the electrode/electrolyte interface, confirming the electrolyte anion has a crucial effect on the charge capacity and rate performance of NiHCF. | Park, Sungjun; Chun, Sang-Eun | Kyungpook Natl Univ, Dept Mat Sci & Met Engn, Daegu 41566, South Korea | 57195715519; 36801080300 | sangeun@knu.ac.kr; | KOREAN JOURNAL OF METALS AND MATERIALS | KOREAN J MET MATER | 1738-8228 | 58 | 12 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;METALLURGY & METALLURGICAL ENGINEERING | 2020 | 1.005 | 76.9 | 0.42 | 2025-06-25 | 5 | 6 | nickel hexacyanoferrate; coprecipitation; electrolyte anion; charge transfer resistance; specific capacity; rate capability | PRUSSIAN BLUE ANALOGS; CATHODE MATERIALS; SUPERIOR CATHODE; HEAT-TREATMENT; INTERCALATION; CRYSTALLIZATION; PERFORMANCE; THIOSULFATE; FRAMEWORK; LI | Charge transfer resistance; Coprecipitation; Electrolyte anion; Nickel hexacyanoferrate; Rate capability; Specific capacity | Cathodes; Charge transfer; Coprecipitation; Electrochemical electrodes; Electrolytes; Iron compounds; Metal ions; Nickel compounds; Redox reactions; Sodium nitrate; Sodium sulfate; Sodium-ion batteries; Sulfur compounds; Aqueous electrolyte; Charge transfer resistance; Electrochemical behaviors; Electrode-electrolyte interfaces; Interfacial charge transfer resistance; Nickel hexacyanoferrate; Open-framework structures; Specific capacities; Fluorine compounds | Korean | 2020 | 2020-12 | 10.3365/kjmm.2020.58.12.896 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Changes in Fruit Characteristics and Expression of Ripening-Related Genes in 'Madoka' Peaches Treated with 1-Methylcyclopropene and Aminoethoxyvinylglycine | Changes of the characteristics were investigated during storage of peach fruits following foliar application of 1-methylcyclopropene (1-MCP, 120 mg.L-1 and 240 mg.L-1), aminoetoxyvinylglcine (AVG, 75 mg.L-1), and a combination of 1-MCP (240 mg.L-1) and AVG (75 mg.L-1) onto peach trees 3 weeks before harvesting. There were no significant differences in fruit characteristics including total soluble solids, acid content, and Hunter's value a between control and 1-MCP- or AVG-treated fruits of 'Madoka' peaches during ambient (25 degrees C) and cold storage (12 degrees C). However, we observed a delayed decrease in firmness, as well as inhibition of ethylene production and respiration during storage of peach fruits after foliar application of 1-MCP, AVG, and AVG combined with 1-MCP in 2017 and in 2018 compared to untreated peach fruits. Quantitative real-time PCR using RNA isolated from peach fruits revealed significantly inhibited expression of sugar accumulation-related genes (polygalacturonase, PpPG and PpPGL; and lipoxygenase, PpLOX), cell wall softening-related gene (pectin methylesterase, PpPME), ethylene biosynthesis-promoting genes (ACC synthase, PpACS1; and ACC oxidase, PpACO), and genes responsive to ethylene receptors (ethylene insensitive protein, PpEIN; and ethylene response sensor 1, PpERS1) in fruits treated with 1-MCP or AVG after harvest. This suggests that foliar application with 1-MCP or AVG can extend the shelf-life of peaches through inhibition of ethylene production and respiration. These results are informative for the development of technology necessary to extend shelf-life, which may ultimately lead to increased consumption and export to foreign countries of peaches produced in Korea. | Lee, Dan Bi; Lee, Guk Jin; Kim, Seung Heui; Kang, In Kyu; Choi, Seong Jin; Yun, Hae Keun | Yeungnam Univ, Dept Hort & Life Sci, Gyongsan 38541, South Korea; Korea Natl Coll Agr & Fisheries, Dept Fruits, Jeonju 54874, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Daegu Catholic Univ, Dept Biotechnol, Gyongsan 38430, South Korea | 57215020579; 57215022588; 57225034883; 56577308800; 55493255400; 25633338500 | haekeun@ynu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 1 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 0.52 | 2025-06-25 | 6 | 6 | ethylene; quantitative real-time PCR; respiration; shelf life; softening | CONTROLLED-ATMOSPHERE STORAGE; ETHYLENE BIOSYNTHESIS; SIGNAL-TRANSDUCTION; QUALITY; 1-MCP; APPLE; AVG; TOMATO; TEMPERATURE; METABOLISM | Ethylene; Quantitative real-time PCR; Respiration; Shelf-life; Softening | Korean | 2020 | 2020 | 10.7235/hort.20200004 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Changes in Fruit Quality Attributes, Cell Wall Materials, and Related Hydrolases Activities in 1-Methylcyclopropene (1-MCP)-treated 'Honggeum' Apples during Cold Storage | We investigated the effects of 1-methylcyclopropene (1-MCP, SmartFresh (TM)) concentrations on fruit quality attributes associated with softening and cell wall metabolism in 'Honggeum' apples. Fruits were treated with 0, 0.5, or 1 mu L.L-1 1-MCP and stored at 0 +/- 1 degrees C for up to 6 months. In comparison with the untreated fruits, both 1-MCP concentrations similarly reduced the internal ethylene concentration and delayed the reduction in firmness and titratable acidity; however, weight loss and soluble solids content were less affected by 0.5 mu L.L-1 1-MCP compared with 1 mu L.L(-1 )1-MCP. Peel color variables (L* and b*) were not changed by either 1-MCP treatment on both the sunlit and shaded sides. Only the a* value on the shaded side was slightly decreased among untreated fruits at 3 and 4 months in comparison with 0.5 mu L.L-1 1-MCP-treated fruits. The uronic acid and total sugar contents of the cell wall and cell wall hydrolase of the enzyme activities (agalactosidase, beta-galactosidase, beta-glucosidase, beta-arabinosidase, beta-xylosidase, and alpha-mannosidase) were much greater in fruits treated with 1 mu L.L-1 1-MCP than in fruits treated with 0.5 mu L.L-1 1-MCP and in untreated fruits. Overall, the results suggested that 1 mu L.L-1 1-MCP may be an effective concentration to retain fruit quality attributes and delay fruit softening in 'Honggeum' apples during cold storage by reducing enzymatic activities related to cell wall hydrolysis. | Yoo, Jingi; Jung, Haram; Win, Nay Myo; Kwon, Jung-Geun; Cho, Young-Je; Jung, Hee-Young; Lee, Dong Hoon; Kang, In-Kyu | Washington State Univ, Tree Fruit Res & Extens Ctr, Wenatchee, WA 98801 USA; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Natl Inst Hort & Herbal Sci, Fruit Res Div, Wonju 55365, South Korea | 56818324500; 57220865235; 42462548000; 57211404168; 55265396300; 7403029383; 55568531225; 56577308800 | kangik@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 38 | 6 | SCIE | HORTICULTURE | 2020 | 0.869 | 77.0 | 2.2 | 2025-06-25 | 14 | 18 | cell wall hydrolase; cell wall total sugar; cell wall uronic acid; ethylene; storability | ETHYLENE RESPONSES; DEGRADING ENZYMES; MOLECULAR-WEIGHT; 1-MCP TREATMENT; METABOLISM; PEAR; MONOSACCHARIDES; BLUEBERRIES; TEMPERATURE; CULTIVARS | Additional cell wall hydrolase; Cell wall total sugar; Cell wall uronic acid; Ethylene; Storability | English | 2020 | 2020 | 10.7235/hort.20200079 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
