| ○ | Article | Changes in properties of 3D printing filaments by extruding at different temperatures and lignin contents | Technical lignin can be used as a plasticizer to provide thermal stability to a material and to facilitate thermal processing. To evaluate the effects of organosolv lignin in polylactic acid (PLA) in this study, we analyzed the performance of 3D printing filaments extruded using different lignin contents and process temperatures. Based on the fracture surface of the fabricated filaments, the fine cracks present in the cross section of the filament decreased as the lignin contents in the PLA and the extruding temperature increased from 150°C to 160°C. However, the mechanical properties of the filament were different at 150°C. When extruded at 150°C without additions of lignin, the neat PLA did not melt completely, resulting in a poor strength performance. Additions of lignin with PLA at the same temperature increased the strength of the filaments owing to heterogeneous nucle-ation. However, upon increasing to 155°C and 160°C, neat PLA had more crystalline substances so that lignin and heterogeneous nucleation instead acted as a weak point for the strength performance. As the lignin content increased, the glass transition point (Tg), crystallization temperature (Tcc), and melting point (Tm) decreased for all temperature conditions evaluated. As the amorphous material was mixed with lignin, the thermal properties of the filament were changed by creating heterogeneous nucleation between the lignin and PLA matrix; however, rapid changes in the Tcc were observed at the 150°C extruding temperature. Because of this dramatic thermal fluctuation, more heterogeneous nucleation occurred, causing changes in the mechanical properties of the filament. © 2020 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | Article | Characteristics and Comparison of 2016 and 2018 Heat Wave in Korea | This study analyzed and compared development mechanisms leading to heat waves of 2016 and 2018 in Korea. The European Centre for Medium-Range Weather Forecasts Reanalysis Interim (ERA Interim) dataset and Automated Surface Observing System data are used for synoptic scale analysis. The synoptic conditions are investigated using geopotential height, temperature, equivalent potential temperature, thickness, potential vorticity, omega, outgoing longwave radiation, and blocking index, etc. Heat waves in South Korea occur in relation to Western North Pacific Subtropical High (WNPSH) pressure system which moves northwest-ward to East Asia during summer season. Especially in 2018, WNPSH intensified due to strong large-scale circulation associated with convective activities in the Philippine Sea, and moved farther north to Korea when compared to 2016. In addition, the Tibetan high near the tropopause settled over Northern China on top of WNPSH creating a very strong anticyclonic structure in the upper-level over the Korean Peninsula. Unlike 2018, WNPSH was weaker and centered over the East China Sea in 2016. Analysis of blocking indices show wide blocking phenomena over the North Pacific and the Eurasian continent during heat wave event in both years. The strong upper-level ridge which was positioned zonally near 60 degrees N, made the WNPSH over the South Korea stagnant in both years. Analysis of heat wave intensity (HWI) and duration (HWD) show that HWI and HWD in 2018 was both strong leading to extreme high temperatures. In 2016 however, HWI was relatively weak compared to HWD. The longevity of HWD is attributed to atmosphere blocking in the surrounding Eurasian continent. | Lee, Hee-Dong; Min, Ki-Hong; Bae, Jeong-Ho; Cha, Dong-Hyun | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, 80 Daehak Ro, Daegu 41566, South Korea; Ulsan Natl Inst Sci & Technol, Sch Urban & Environm Engn, Ulsan, South Korea | Cha, Dong-Hyun/F-4901-2015 | kmin@knu.ac.kr; | ATMOSPHERE-KOREA | ATMOS-KOREA | 1598-3560 | 2288-3266 | 30 | 1 | ESCI | METEOROLOGY & ATMOSPHERIC SCIENCES | 2020 | N/A | 27 | Heat wave; western north pacific subtropical high; Tibet high; blocking | ATMOSPHERIC BLOCKING; SOUTH-KOREA; SUMMER; CHINA; MORTALITY; FREQUENT; LONGER; EAST | Korean | 2020 | 2020 | 10.14191/atmos.2020.30.1.001 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Characteristics of GaN-Based Nanowire Gate-All-Around (GAA) Transistors | We investigate the DC, C-V, and pulse performances in GaN-based nanowire gate-all-around (GAA) transistors with two kinds of geometry: one is AlGaN/GaN heterostructure with two dimensional electron gas (2DEG) channel and the other is only GaN layer without 2DEG channel. From I-V and C-V curves, the fabricated GaN nanowire GAA transistor with AlGaN layer clearly exhibits normally-on operation with negative threshold voltage (V-th) due to the existence of 2DEG channel on the trapezoidal shaped GaN nanowire. On the other hand, the GaN nanowire GAA transistor without AlGaN layer presents a positive V-th (normally-off operation) due to the absent of 2DEG channel on the triangle shaped GaN nanowire. However, both devices show the similar temperature-dependent I-V characteristics due to the combination of bulk channel and surface channel in GaN nanowire GAA channel are mostly contributed, rather than the 2DEG channel. GaN-based nanowire GAA transistors demonstrate to almost negligible current collapse phenomenon due to the perfect GAA gate structure in GaN nanowire. The proposed GaN-based nanowire GAA transistors are very promising candidate for both high power device and nano-electronics application. | Im, Ki-Sik; Reddy, Mallem Siva Pratap; Choi, Jinseok; Hwang, Youngmin; Roh, Jea-Seung; An, Sung Jin; Lee, Jung-Hee | Kumoh Natl Inst Technol, Adv Mat Res Ctr, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Adv Mat Sci & Engn, Gumi 39177, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | An, Sung/A-2869-2009 | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 7 | 0 | AlGaN/GaN; 2DEG; Gate-All-Around (GAA); C-V Characteristics; Temperature Measurement; Pulse Measurement; Current Collapse | ELECTRON-MOBILITY TRANSISTORS | English | 2020 | 2020-07 | 10.1166/jnn.2020.17784 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | Characterization of carboxylated cellulose nanocrystals from recycled fiberboard fibers using ammonium persulfate oxidation | As a way of finding value-added materials from waste medium density fiberboard (MDF), this study characterized cellulose nanocrystals (CNCs) isolated by ammonium persulfate (APS) oxidation using recycled MDF fibers. Chemical composition of the recycled MDF fibers was done to quantify α-cellulose, hemicellulose, lignin, nitrogen, ash and extractives. The APS oxidation was performed at 60 °C for 16 h, followed by ultrasonication, which resulted in a CNC yield of 11%. Transmission electron microscope images showed that rod-like CNCs had an average length and diameter of 167±47 nm and 8.24±2.28 nm, respectively, which gave an aspect ratio of about 20. The conductometric titration of aqueous CNCs suspension resulted in a carboxyl content of 0.24 mmol/g and the degree of oxidation was 0.04. Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy clearly showed the presence of carboxyl group on the CNCs prepared by the APS oxidation. The change of pH of the aqueous CNC suspension from 4 to 7 converted the carboxyl group to sodium carboxylate group. These results showed that the APS oxidation was facile and CNCs had a one-step preparation method, and thus suggested an optimization of the oxidation condition in future. © 2020, Korean Society of Wood Science Technology.

| ○ | ○ | Article | Characterization of Chlorella sorokiniana and Chlorella vulgaris fatty acid components under a wide range of light intensity and growth temperature for their use as biological resources | This study aims to characterize the potential of three strains of microalgal species (Chlorella sorokiniana KNUA114 and KNUA122; C. vulgaris KNUA104) for use as feedstock, based on their fatty acid compositions. Each strain was molecularly identified using four marker genes (ITS, SSU, rbcL, and tufA) and phylogenetically characterized. C. sorokiniana and C. vulgaris collected from Ulleung Island, South Korea, were homologous with other known species groups. Samples' fatty acid components were measured using GC/MS analysis in growth temperatures of 10 degrees C, 25 degrees C, and 35 degrees C. The growth rate of C. sorokiniana strains was higher than that of C. vulgaris under high temperature conditions, confirming the potential industrial applicability of the former as feedstock material. Additionally, saturated fatty acid contents and productivities increased as biological resources of the C. sorokiniana strains were higher than those of C. vulgaris under high light intensity and temperature conditions. These results suggest that the fatty acid components of C. sorokiniana strains may potentially be used as biological resources (e.g., feedstock). | Yun, Hyun-Sik; Kim, Young-Saeng; Yoon, Ho-Sung | Kyungpook Natl Univ, Dept Biol, Coll Nat Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Ulleung Do & Dok Do, Daegu 41566, South Korea | 57215320824; 35798433500; 7402990205 | kyslhh1228@hanmail.net;hsy@knu.ac.kr; | HELIYON | HELIYON | 2405-8440 | 6 | 7 | ESCI | MULTIDISCIPLINARY SCIENCES | 2020 | N/A | 1.36 | 2025-06-25 | 40 | 49 | Bioinformatics; Biotechnology; Genetics; Microbiology; Molecular biology; Plant biology; Biological resource; Chlorella sorokiniana; Chlorella vulgaris; Fatty acid components; Microalgae | BIODIESEL PRODUCTION; LIPID-ACCUMULATION; GREEN-ALGAE; MICROALGAE; NITROGEN; FOOD; TREBOUXIOPHYCEAE; CHLOROPHYTA; CHLAMYDOMONAS; CYANOBACTERIUM | Bioinformatics; Biological resource; Biotechnology; Chlorella sorokiniana; Chlorella vulgaris; Fatty acid components; Genetics; Microalgae; Microbiology; Molecular biology; Plant biology | English | 2020 | 2020-07 | 10.1016/j.heliyon.2020.e04447 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Characterization of hot water extract from Korean deer velvet antler (Cervus canadensis erxleben) | Velvet antlers (VA) sourced from red (Cervus elaphus), sika (C. nippon), and elk (C. canadensis) deer have become increasingly popular in Chinese, Korean and Japanese traditional and oriental medicines as supplements for disease prevention. Therefore, this study aimed to determine the chemical components (proximate composition, amino, uronic, and sialic acids) and to characterize the bacterial profile of VA extract. The yield and contents of uronic and sialic acids extracted from VA at 98-100℃ for 29-36 sec were determined to be 40.71%, 28.06 mg/g and 0.73 mg/g, respectively. Overall, proximate parameters were higher in extracts recovered at 100℃ compared with 90℃, and these parameters were: moisture (4.66%), crude protein (86.63%), crude fat (3.23%), crude ash (4.1%), and carbohydrate content (5.43%). Alanine was the most abundant among the identified amino acids. Analysis of 16S rRNA sequence identified 12 bacterial species, including seven gram-positive and five gram-negative bacteria. Among all bacteria, Chryseobacterium indologenes, Shigella flexneri ATCC 29903, Staphylococcus equorum, Staphylococcus xylosus, Staphylococcus succinus, and Vagococcus fluvialis had 100% identity in the VA extract. The morphology of C. indologene, S. flexneri ATCC 29903, and V. fluvialis was bacilli, whereas S. equorum, S. succinus, and S. xylosus were cocci. Copyright © The Korean Society of Food Preservation.

| ○ | Article | Charge Based Current-Voltage Model for the Silicon on Insulator Junctionless Field-Effect Transistor | In this study, we propose an accurate and simple current voltage model for an SOI-JLFET based on a solution of the Poisson equation. The model is divided into three regions: accumulation, accumulation depletion, and depletion. The charge density in each region is calculated with the Poisson equation and region-specific boundary conditions, and then the current is obtained by integrating the charge density with consideration of the v(ds) effect. The proposed model, which was implemented in HSPICE using Verilog-A, was validated using TCAD simulation for various physical conditions such as SOI channel thickness, gate oxide thickness, and channel doping concentration type. According to simulation results by the error rate calculation, our model shows more than 90% accuracy. | Jeong, Yongjin; Kang, In Man; Cho, Seongjae; Park, Jisun; Shin, Hyungsoon | Ewha Womans Univ, Dept Elect & Elect Engn, Seoul 03760, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 702701, South Korea; Gachon Univ, Dept Elect Engn, Gyeonggi Do 461701, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 8 | 0 | Junctionless Field-Effect Transistor (JLFET); Silicon on Insulator Junctionless Field-Effect Transistor (SOI-JLFET); Charge-Based; Current-Voltage Model; Current Model; Circuit Simulation | NANOWIRE | English | 2020 | 2020-08 | 10.1166/jnn.2020.17795 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | ○ | Article | Chemical Constituents from the Aerial Parts of Artemisia capillaris Thunb. and Their Anti-allergic and Anti-inflammatory Effects | Artemisia capillaris Thunb. (Compositae) is a traditional medicinal plant with various pharmacological activities. To elucidate new anti-allergic and anti-inflammatory constituents, the aerial parts of A. capillaries were investigated to afford a new compound, (6E,8E)-6-methylundeca-6,8-diene-2,5,10-trione (17) together with 19 known compounds (1 - 16, 18 - 20). The structures of these compounds were determined by extensive spectroscopic analyses including 1D, 2D NMR, HREIMS, and optical rotation [alpha](D) . The absolute configuration of compound 2 was determined to be S form for the first time. All isolates (1 - 20) were tested their inhibitory effects on interleukin 2 (IL-2) expression in T cells and NO production in lipopolysaccharide (LPS)-stimulated RAW246.7. Among them, compounds 10, 11, 19, and 20 reduced IL-2 expression in a dose-dependent manner. In addition, compound 10 also inhibited NO production with an IC50 value of 37.3 +/- 0.4 mu M. | Thi Thu Nguyen; Thi Oanh Vu; Thao Quyen Cao; Byung Sun Min; Kim, Jeong Ah | Kyungpook Natl Univ, Coll Pharm, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Daegu Catholic Univ, Coll Pharm, Drug Res & Dev Ctr, Gyongsan 38430, South Korea | Quyen, Cao/AAP-9678-2020 | 57216362874; 57218248176; 57216363854; 57195057619; 24722570900 | jkim6923@knu.ac.kr; | NATURAL PRODUCT SCIENCES | 1226-3907 | 26 | 1 | 0.09 | 2025-06-25 | 1 | 1 | 6E 8E-6-methylundeca-6 8-diene-2 5 10-trione; Anti-allergic; Antiinflammatory; Artemisia capillaris Thunb; IL-2; NO inhibition | 4 (1 methoxyethyl)phenol); 6 methylundeca 6,8 diene 2,5,10 trione; Artemisia capillaris extract; interleukin 2; nitric oxide; tumor necrosis factor; unclassified drug; antiallergic activity; antiinflammatory activity; Artemisia capillaris; Article; cell culture; cell viability; cell viability assay; cytotoxicity; drug activity; Fourier transform; gene expression; high performance liquid chromatography; IC50; medicinal plant; MTT assay; particle size; protein expression; proton nuclear magnetic resonance; real time polymerase chain reaction; reverse transcription polymerase chain reaction; spectroscopy; T lymphocyte; thin layer chromatography; Western blotting | English | 2020 | 2020 | 10.20307/nps.2020.26.1.90 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | Article | Circuit configuration of asymmetric mixed MMC in bipolar HVDC transmission systems | Among the MMC topologies for bipolar HVDC systems, the asymmetric mixed MMC is considered as promising and attractive circuit due to the cost saving, less loss, DC fault ride-through capability, and free and quick DC bus voltage regulation. In this paper, the reasonable circuit configuration of an asymmetric mixed MMC in bipolar HVDC transmission system is introduced. In the application of asymmetric mixed MMC for the bipolar HVDC system, the induced DC bias voltage into AC transformer at normal operation according to the placement of submodules is investigated and discussed. Furthermore, the optimal submodule arrangement is proposed considering the busbar single line-to-ground fault at AC side of MMC.

| ○ | ○ | Proceedings Paper | Classification of Dementia Associated Disorders Using EEG based Frequent Subgraph Technique | Dementia associated disorders such as vascular dementia, frontotemporal dementia and Alzheimer dementia lead to cognitive impairment. Discrimination of dementia associated disorders has reamined a challenging task as they have overlapping underlying complex structures and display similar clinical features. In this work, we explore an EEG based frequent subgraph searching technique to characterize stages of brain functional networks of mild cognitive impairment (MCI), Alzheimer's disease (AD) and vascular dementia (VD) subjects in comparison with healthy control (HC) subjects. To identify the frequent subgraph related to dementia, we first formulated the brain functional network based on the phase information of EEG with mutual information as a measure. The whole network is then divided into sub-regions and frequent sub-graph search is performed. The identified frequent subgraphs were employed to discriminate the dementia associated disorders from the data recorded from 10 healthy and 32 dementia subjects in various stages. Results show that the proposed method has the potential to quantify the disease progression using brain functional connectivity and the identified networks can aid in the diagnosis of dementia associated disorders. | Adebisi, Abdulyekeen T.; Gonuguntla, Venkateswarlu; Lee, Ho-Won; Veluvolu, Kalyana C. | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Samsung Med Ctr, Med Sci Res Inst, Seoul, South Korea; Kyungpook Natl Univ Hosp, Neurol & Neurosurg Ctr, Chilgok, Daegu, South Korea | Veluvolu, Kalyana/C-6366-2011; Gonuguntla, Venkateswarlu/AAH-5239-2021 | 57220004878; 55696595000; 35337240700; 8703318200 | veluvolu@ee.knu.ac.kr; | 20TH IEEE INTERNATIONAL CONFERENCE ON DATA MINING WORKSHOPS (ICDMW 2020) | 2375-9232 | 0.25 | 2025-06-25 | 4 | 6 | EEG; Dementia Associated Disease; Mutual Information (MI); Reactive Band; Functional Connectivity; Brain Functional Network; Frequent Subgraph Search | MUTUAL INFORMATION ANALYSIS; ALZHEIMERS-DISEASE; FUNCTIONAL CONNECTIVITY; ENTROPY | Brain Functional Network; Dementia Associated Disease; EEG; Frequent Subgraph Search; Functional Connectivity; Mutual Information (MI); Reactive Band | Data mining; Diagnosis; Disease control; Alzheimer's disease; Brain functional networks; Cognitive impairment; Disease progression; Frontotemporal dementias; Functional connectivity; Mild cognitive impairments (MCI); Searching techniques; Neurodegenerative diseases | English | 2020 | 2020 | 10.1109/icdmw51313.2020.00087 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Review | Clinical application of video head impulse test in acute vestibular syndrome | Acute unilateral vestibulopathy (AUV) is the recommended term [rather than the more widely used 'vestibular neuritis (VN)'] for all pathologies involving sudden impairment of the unilateral peripheral vestibular function regardless of the exact location of the lesion. Acute vestibular syndrome (AVS) is an upper-level entity of AUV, which is the most common cause of AVS, and includes acute central vertigo. AVS typically presents with the symptoms of new onset continuous vertigo, gait instability, and nausea/vomiting lasting several days to weeks. The video head impulse test (vHIT) was recently developed and has been widely adopted at clinics and emergency centers. In this study, we will review the differential diagnosis of AVS using vHIT. In addition, we will describe the subtypes of VN and the use of vHIT for follow-up testing in AVS.

| ○ | Article | Clinical Characteristics and Long-Term Prognosis of Alport Syndrome: A Retrospective Single-Center Study | Purpose: Alport syndrome (AS) is one of the most common inherited renal dis-eases caused due to mutations of genes encoding specific proteins of the type IV collagen family, and its major clinical manifestations include progressive renal failure, sensorineural deafness, and ocular abnormalities. We investigated the clinical characteristics and long-term prognosis of AS in Korean pediatric and adult populations. Methods: We conducted a retrospective review of medical records of 33 children and adults who had been diagnosed or treated with AS from 1985 to 2019. Results: The mean age of the 33 patients diagnosed with AS was 16.2±13.6 years, and the male-to-female ratio was 2:1. At the first visit, recurrent gross hematuria was the most common initial symptom. In 10 of 33 patients (30.3%), sensorineural hearing loss (SNHL) was diagnosed, but none had ophthalmic problems. Moreover, 11 of 33 patients (33.3%) had advanced to end-stage renal disease (ESRD), and a significant difference was observed in the age of the patients who progressed to ESRD based on the presence or absence of SNHL (P=0.035). Conclusion: SNHL in AS can be an important prognostic factor for long-term de terioration of renal function. Further investigation is required to confirm the clinical course and the genetic characteristics of AS in Korea through prospective national cohort studies. © 2020 The Korean Society of Pediatric Nephrology. | Jang, Hea Min; Baek, Hee Sun; Park, Sun-Hee; Kim, Yong-Lim; Kim, Chan-Duck; Jung, Hee-Yeon; Cho, Jang-Hee; Han, Man Hoon; Kim, Yong Jin; Cho, Min Hyun | Department of Pediatrics, Internal Medicine, School of Medicine, Daegu, South Korea; Department of Pediatrics, Internal Medicine, School of Medicine, Daegu, South Korea; Department of Pediatrics Pathology, School of Medicine, Daegu, South Korea; Department of Pediatrics Pathology, School of Medicine, Daegu, South Korea; Department of Pediatrics Pathology, School of Medicine, Daegu, South Korea; Department of Pediatrics Pathology, School of Medicine, Daegu, South Korea; Department of Pediatrics Pathology, School of Medicine, Daegu, South Korea; Kyungpook National University, School of Medicine, Daegu, South Korea; Kyungpook National University, School of Medicine, Daegu, South Korea; Department of Pediatrics, Internal Medicine, School of Medicine, Daegu, South Korea | 57216601178; 56689379700; 7501831741; 55633533600; 59216189400; 57196396467; 7403536291; 57194067936; 56150365500; 7401727726 | chomh@knu.ac.kr; | Childhood Kidney Diseases | 2384-0242 | 24 | 2 | 0.12 | 2025-06-25 | 1 | Alport syndrome; End-stage renal disease; Sensorineural hearing loss | English | Final | 2020 | 10.3339/jkspn.2020.24.2.91 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Clinical Outcomes of Cervical Transforaminal Epidural Block Using Local Anesthetics with or without a Steroid for Cervical Spondylotic Radiculopathy | Study Design: A retrospective chart review. Objectives: To evaluate and compare the clinical outcomes of cervical transforaminal epidural block (CTEB) using local anesthetics with or without a steroid for cervical spondylotic radiculopathy (CSR). Summary of Literature Review: The typical mixture for a CTEB is a combination of local anesthetics with a non-particulate steroid. However, there are potential complications related to steroid injections such as steroid-induced osteoporosis, hypothalamus-pituitary-adrenal gland axis suppression, and hyperglycemia. Materials and Methods: From January 2018 to October 2019, 35 patients who underwent CTEB for CSR were enrolled in this study. Cases with arm pain over 4 on a visual analog scale (VAS) were included. In the first 19 cases, a combination of 1 mL of 1% lidocaine and 1 mL of dexamethasone was used (group A), and in the next 16 cases, 1 mL of 1% lidocaine mixed with 1 mL of normal saline was used (group B). Arm pain VAS and the Neck Disability Index (NDI) were obtained perioperatively. Results: Baseline characteristics were not significantly different between the two groups. In both groups, the arm pain VAS significantly decreased at 30 minutes, 2 weeks, and 6 weeks post-injection compared to pre-injection values. However, the arm pain aggravated 12 weeks post-injection. The NDI of both groups significantly improved 6 weeks post-injection compared to pre-injection. The clinical outcomes of arm pain VAS and NDI at 30 minutes, 2 weeks, and 6 weeks post-injection, as well as the amounts of change, were not significantly different between both groups. Conclusions: CTEB for CSR without a steroid improved symptoms by 6 weeks. The degree of improvement was similar to when CTEB was performed with a steroid in terms of VAS and NDI. © 2020 Korean Society of Spine Surgery Journal of Korean Society of Spine Surgery. | Park, Eugene J.; Kim, Seong-Min; Chung, Seungho; Min, Woo-Kie | Department of Orthopedic Surgery, Kyungpook National University Hospital, Kyungpook National University School of Medicine, Daegu, South Korea; Department of Orthopedic Surgery, Kyungpook National University Hospital, Kyungpook National University School of Medicine, Daegu, South Korea; Department of Orthopedic Surgery, Kyungpook National University Hospital, Kyungpook National University School of Medicine, Daegu, South Korea; Department of Orthopedic Surgery, Kyungpook National University Hospital, Kyungpook National University School of Medicine, Daegu, South Korea | 55371642100; 57192988525; 57221219695; 8548041000 | oswkmin@gmail.com; | Journal of Korean Society of Spine Surgery | 2093-4378 | 27 | 4 | 0 | 2025-06-25 | 0 | Cervical vertebrae; Dexamethasone; Lidocaine; Nerve block | English | Final | 2020 | 10.4184/jkss.2020.27.4.115 | 바로가기 | 바로가기 |
