| ○ | Article | Magnetic resonance imaging evaluation of the prostate in normal dogs | The aims of this study were to describe the appearance and size of the normal canine prostate using magnetic resonance (MR) imaging and to calculate the apparent diffusion coefficient (ADC) values. MR images were obtained from seven intact male beagle dogs using a 1.5 T MR unit. The sequences included pre- and post-contrast T1- and T2-weighted imaging with and without fat saturation. The signal intensity of the prostate was compared with the adjacent musculature, fat, and urine in the urinary bladder. We recorded the mean prostatic length, width, and height and the length of the sixth lumbar vertebral body (L6). In addition, the prostatic length (rL), width (rW), and height (rH) ratios to L6 were calculated. Diffusion-weighted images of the prostate were obtained and ADC values were calculated. The prostate was bilobed and oval-shaped, homogenous on T1-weighted images, and heterogeneous with radiating lines on T2-weighted images. Post-contrast T1-weighted sequences showed contrast enhancement of the central and radiating striations. The prostatic capsule was clearly identified on post-contrast T1-weighted images with fat saturation. The ADC values were 1.72-2.04 × 10-3 mm2/sec (mean, 1.88 × 10-3 mm2/sec). Knowledge of the normal appearance of the prostate on MR images is essential to assess prostatic diseases in dogs. © 2020, Korean Society of Veterinary Clinics.

| ○ | Article | Marker compound contents and antioxidant capacities of the taproot and lateral root of danshen (Salvia miltiorrhiza radix) | In this study, the marker compound contents of both the taproot and lateral root of Danshen (Salvia miltiorrhiza Radix), which is cultivated in Korea, were investigated. The salvianolic acid B content was the highest in the taproot (5.17– 6.75%) and lateral root (3.99–5.69%). The cryptotanshinone, tanshinone I, and tanshinone IIA contents were higher in the lateral root than in the taproot of Danshen (p <0.05). Principal component analysis results revealed that the taproot was correlated to the salvianic acid A, rosmarinic acid, salvianolic acid B, and salvianolic acid A contents, whereas the lateral root was correlated to the cryptotanshinone, tanshinone I, and tanshinone IIA contents. The total phenolic content and total flavonoid content of the taproot were higher than those of the lateral root (p <0.05); however, the antioxidant activities of the taproot and lateral root of Danshen were similar. The salvianolic acid B content was correlated to the TPC of the taproot (r=0.748) and the 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity of the lateral root (r=0.847). This study could provide useful information for the classification of Danshen as a herbal medicinal product. © The Korean Society for Applied Biological Chemistry 2020. | Seong, Gi-Un; Chung, Shin-Kyo | School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea | 56814555600; 7404292790 | kchung@knu.ac.kr; | Journal of Applied Biological Chemistry | 1976-0442 | 63 | 1 | 0.21 | 2025-06-25 | 3 | Antioxidant; Danshen; Principal component analysis; Salvianolic acid B; Tanshinone IIA | English | Final | 2020 | 10.3839/jabc.2020.003 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Measurement of the Coating Temperature Evolution during Atmospheric Plasma Spraying | For more effective temperature control of atmospheric plasma sprayed (APS) zirconia thermal barrier coating, understanding of the parameters, which influence the substrate temperature, is essential and also more numerical results based on the experimental data are required. This study aims to investigate the substrate temperature control during an APS process. The APS process deals with air-cooled systems, plasma-gas flow, powder feed rate, robot velocity, and substrate effect on the substrate surface temperature control during the process. This systematic approach will help to handle the temperature control, and thus lead to better coating quality. | Lee, Kiyoung; Oh, Hyunchul | Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju 37224, South Korea; Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, Sangju 37224, South Korea; Gyeongnam Natl Univ Sci & Technol GNTECH, Future Convergence Technol Res Inst, Dept Energy Engn, Jinju 52725, South Korea | Oh, Hyunchul/G-5697-2018; Lee, Kiyoung/J-8680-2013 | 57219211501; 55340650900 | kiyoung@knu.ac.kr;oh@gntech.ac.kr; | APPLIED CHEMISTRY FOR ENGINEERING | APPL CHEM ENG | 1225-0112 | 1228-4505 | 31 | 6 | ESCI | ENGINEERING, CHEMICAL | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | Thermal barrier coatings; Atmospheric plasma spray; Thermal spray processes | APS PROCESS PARAMETERS; WEAR BEHAVIOR | Atmospheric plasma spray; Thermal barrier coatings; Thermal spray processes | Korean | 2020 | 2020-12 | 10.14478/ace.2020.1071 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Measurement of the mutual induction coefficients in dual solenoid structures | The phase differences (δφ) between the applied alternating current (AC) voltage with various frequencies (f) to a solenoid and the generated AC current were measured, and the self-induction coefficient (L) was calculated using f, resistance and δφ. In the dual solenoid structure, δφ between the AC voltage of the primary solenoid (Solpri) and the induced electromotive force (ϵ) of various secondary solenoids (Solsec) was measured. δφ is caused by L and f of the Solpri, but the change in L of the Solsec was not affected. In the above experiment, we was able to calculate the mutual-induction coefficient (M) of the dual solenoid structure by using the maximum value of the AC voltage of the Solpri and the maximum induced . of the Solsec. As L increased, the induced . generated by the Solsec increased, thus, M increased. The experiments are designed suitably for students to understand δφ in the AC circuit using solenoids, find L, and understand the relationship between L and M in the dual solenoid structure. © 2020 The Korean Physical Society.

| ○ | Article | Measurement of thoracic limb joint reference angles in purebred shih-tzu dogs by computed tomography | The purpose of this study was to establish normal values for the thoracic limb joint reference angles in Shih Tzu dogs and to describe the standardized CT methodology for measuring the joint reference angle of the humerus. Five pairs of thoracic limbs of Shih Tzu dogs were collected for the CT scans in this study. Three blinded observers measured the joint reference angle of the humerus and radius for each dog by using CT scans in the frontal, sagittal, and axial planes. The means (± SDs) for the average of the right and left humeral joint reference angles were as follows: mMPHA, 83.74 ± 3.95o; mLDHA, 85.04 ± 2.57o; mCaPHA, 46.75 ± 2.20o; mCrDHA, 79.47 ± 1.97o; and HTA, 19.16 ± 2.38o. Means (± SD) for the average of right and left of the radial joint reference angles were as follows: aMPRA, 85.04 ± 1.58o; aLDRA, 87.59 ± 1.37o; aCrPRA, 84.60 ± 1.46o; aCdDRA, 84.27 ± 1.79o; and RTA, 20.91 ± 3.00o. The intraclass correlation coefficients (ICCs) of the joint reference angles for the inter-and intraobserver reliability were good to excellent, except those for the mCrHA and HTA were moderate. Our results suggest that the method of measuring joint reference angles of other long bones by using CT can be applied to thoracic limbs and can extract valid values for one specific breed. © 2020, Korean Society of Veterinary Clinics.

| ○ | ○ | Review | Melatonin: Awakening the Defense Mechanisms during Plant Oxidative Stress | Melatonin is a multifunctional signaling molecule that is ubiquitously distributed in different parts of a plant and responsible for stimulating several physio-chemical responses to adverse environmental conditions. In this review, we show that, although plants are able to biosynthesize melatonin, the exogenous application of melatonin to various crops can improve plant growth and development in response to various abiotic and biotic stresses (e.g., drought, unfavorable temperatures, high salinity, heavy metal contamination, acid rain, and combined stresses) by regulating antioxidant machinery of plants. Current knowledge suggests that exogenously applied melatonin can enhance the stress tolerance of plants by regulating both the enzymatic and non-enzymatic antioxidant defense systems. Enzymic antioxidants upregulated by exogenous melatonin include superoxide dismutase, catalase, glutathione peroxidase, and enzymes involved in the ascorbate-glutathione cycle (ascorbate peroxidase, monodehydroascorbate reductase, dehydroascorbate reductase, and glutathione reductase), whereas levels of non-enzymatic antioxidants such as ascorbate, reduced glutathione, carotenoids, tocopherols, and phenolics are also higher under stress conditions. The enhanced antioxidant system consequently exhibits lower lipid peroxidation and greater plasma membrane integrity when under stress. However, these responses vary greatly from crop to crop and depend on the intensity and type of stress, and most studies to date have been conducted under controlled conditions. This means that a wider range of crop field trials and detailed transcriptomic analysis are required to reveal the gene regulatory networks involved in the between melatonin, antioxidants, and abiotic stress. | Khan, Adil; Numan, Muhammad; Khan, Abdul Latif; Lee, In-Jung; Imran, Muhammad; Asaf, Sajjad; Al-Harrasi, Ahmed | Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 611, Oman; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea | ; Numan, Muhammad/AAB-5344-2022; Ul-Hamid, Anwar/B-7297-2015; Khan, Adil/AAC-5160-2022; Khan, Abdul/H-5910-2011; Imran, Muhammad/AFL-6590-2022; Asaf, Sajjad/ABA-3647-2021; Lee, In-Jung/GLS-0432-2022 | 57200917937; 59012967300; 26639372800; 16425830900; 58282433800; 56595059900; 6506093146 | adilkhan@unizwa.edu.om;numan2@unizwa.edu.om;latifepm78@yahoo.co.uk;ijlee@knu.ac.kr;muhammad.imran@yahoo.com;sajjadasaf@unizwa.edu.om;aharrasi@unizwa.edu.om; | PLANTS-BASEL | 2223-7747 | 9 | 4 | 4.06 | 2025-06-25 | 152 | 172 | melatonin; ROS; antioxidant; ascorbate-glutathione cycle | REACTIVE OXYGEN; ANTIOXIDANT ENZYMES; ASCORBATE PEROXIDASE; SUPEROXIDE-DISMUTASE; EXOGENOUS MELATONIN; ENHANCED TOLERANCE; DROUGHT TOLERANCE; DEHYDROASCORBATE REDUCTASE; LIPID-PEROXIDATION; SEED-GERMINATION | Antioxidant; Ascorbate-glutathione cycle; Melatonin; ROS | English | 2020 | 2020-04 | 10.3390/plants9040407 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

| ○ | Review | Methanol fixation for scanning electron microscopy of plants | Plant specimens for scanning electron microscopy (SEM) are commonly treated using standard protocols. Conventional fixatives consist of toxic chemicals such as glutaraldehyde, paraformaldehyde, and osmium tetroxide. In 1996, methanol fixation was reported as a rapid alternative to the standard protocols. If specimens are immersed in methanol for 30 s or longer and critical-point dried, they appear to be comparable in preservation quality to those treated with the chemical fixatives. A modified version that consists of methanol fixation and ethanol dehydration was effective at preserving the tissue morphology and dimensions. These solvent-based fixation and dehydration protocols are regarded as rapid and simple alternatives to standard protocols for SEM of plants. © 2020, The Author(s). | Kim, Ki Woo | School of Ecology and Environmental System, Kyungpook National University, Sangju, 37224, South Korea, Tree Diagnostic Center, Kyungpook National University, Sangju, 37224, South Korea | 57201369889 | kiwoo@knu.ac.kr; | Applied Microscopy | 2287-5123 | 50 | 1 | 0.11 | 2025-06-25 | 7 | Fixation; Glutaraldehyde; Methanol | Acetal resins; Dehydration; Polyols; Scanning electron microscopy; Ethanol dehydration; Fixation; Glutaraldehydes; Osmium tetroxide; Paraformaldehydes; Plant specimens; Solvent based; Standard protocols; Tissue morphology; Toxic chemicals; Methanol | English | Final | 2020 | 10.1186/s42649-020-00028-5 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Book chapter | Microbial enzymes and their mechanisms in the bioremediation of pollutants | Bioremediation is the process, with the help of microbes or their enzymes, to remove the pollutants present in the environment and change them into non-toxic compounds. Microbial enzymes have a wide range of metabolic activities and are involved in the transformation of pollutants. Enzymes like oxidoreductase, hydrolases, monooxygenase, dioxygenase, methyltransferases, and lipases are involved in the degradation process. Oxidoreductase catalyzes the transfer of electron and proton from the reduced organic substrate to another chemical compound from donor to acceptor. Monooxygenase and dioxygenases are the transferring oxygen from molecular oxygen (O2) utilizing FAD/NADH/NADPH as a co-substrate in this process. Lyases catalyze the cleavage of the bonds by elimination, leaving double bonds. Peroxidases catalyze the oxidation of lignin and other phenolic compounds at the expense of hydrogen peroxide (H2O2) in the presence of a mediator. Lipases also involve catalyzing the hydrolysis of triacylglycerols to glycerol and free fatty acids. © 2021, IGI Global. | Rajamanickam, Karthika; Balakrishnan, Jayanthi; Thangaswamy, Selvankumar; Muthusamy, Govarthanan | Mahendra Arts and Science College (Autonomous), India; Mahendra Arts and Science College (Autonomous), India; Mahendra Arts and Science College (Autonomous), India; Kyungpook National University, South Korea | 57654151200; 57653596300; 24485017700; 54881927600 | Recent Advancements in Bioremediation of Metal Contaminants | 0 | 2025-06-25 | 0 | English | Final | 2020 | 10.4018/978-1-7998-4888-2.ch003 | 바로가기 | 바로가기 | |||||||||||||||||||||
| ○ | Article | Mid-term (2009-2019) demographic dynamics of young beech forest in Albongbunji Basin, Ulleungdo, South Korea | Background: The stem exclusion stage is a stage of forest development that is important for understanding the subsequent understory reinitiation stage and maturation stage during which horizontal heterogeneity is formed. Over the past 11 years (2009–2019), we observed a deciduous broad-leaved forest in the Albongbunji Basin in Ulleungdo, South Korea in its stem exclusion stage, where Fagus engleriana (Engler’s beech) is the dominant species, thereby analyzing the changes in the structure (density and size distributions), function (biomass and species richness), and demographics. Results: The mean stem density data presented a bell-shaped curve with initially increasing, peaking, and subsequently decreasing trends in stem density over time, and the mean biomass data showed a sigmoidal pattern indicating that the rate of biomass accumulation slowed over time. Changes in the density and biomass of Fagus engleriana showed a similar trend to the changes in density and biomass at the community level, which is indicative of the strong influence of this species on the changing patterns of forest structure and function. Around 2015, a shift between recruitment and mortality rates was observed. Deterministic processes were the predominant cause of tree mortality in our study; however, soil deposition that began in 2017 in some of the quadrats resulted in an increase in the contribution of stochastic processes (15% in 2019) to tree mortality. The development of horizontal heterogeneity was observed in forest gaps. Conclusions: Our observations showed a dramatic shift between the recruitment and mortality rates in the stem exclusion stage, and that disturbance increases the uncertainty in forest development increases. The minor changes in species composition are likely linked to regional species pool and the limited role of the life-history strategy of species such as shade tolerance and habitat affinity. Our midterm records of ecological succession exhibited detailed demographic dynamics and contributed to the improvement of an ecological perspective in the stem exclusion stage. © 2020, The Author(s). | Cho, Yong-Chan; Sim, Hyung Seok; Jung, Songhie; Kim, Han-Gyeoul; Kim, Jun-Soo; Bae, Kwan-Ho | Conservation Center for Gwangneung Forest, Korea National Arboretum, Pocheon, 11186, South Korea; Conservation Center for Gwangneung Forest, Korea National Arboretum, Pocheon, 11186, South Korea, Department of Forest Resources, Graduate School of Kookmin University, Seoul, 02707, South Korea; Conservation Center for Gwangneung Forest, Korea National Arboretum, Pocheon, 11186, South Korea; Conservation Center for Gwangneung Forest, Korea National Arboretum, Pocheon, 11186, South Korea; Korean Institute of Vegetation Science, Daegu, 41001, South Korea; School of Ecology & Environmental System, Kyungpook National University, Sangju, 37224, South Korea | 55268507800; 57219992750; 57196153364; 59615252000; 57221538968; 35108758200 | bz0288@korea.kr; | Journal of Ecology and Environment | 2288-1220 | 44 | 1 | 0.1 | 2025-06-25 | 1 | Demographic dynamics; Fagus engleriana; Forest dynamics; Forest succession; Oceanic island; Stem exclusion stage | English | Final | 2020 | 10.1186/s41610-020-00170-x | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Mitigating Interference and Energy Issues in Smart Homes using Internet of Things | The smart home is extensively preferred, as it improves the residents' lifestyles involving many disciplines, i.e., security, lighting, etc. The wide expansion of smart home increases size and complexity in network, therefore, it is crucial to tackle the numerous challenges associated to data loss attributable to efficient energy and interference management. In this research article, a specific smart home control system is proposed using ZigBee based on co-coordinator. The proposed system is composed of three components: 1) interference controlling system to control wireless interference among heterogeneous devices, 2) advanced energy management system to optimize the energy utilization and integrated the light source with sunlight, and 3) management control agent to manage the electronic devices and time efficiently.
