| ○ | ○ | Article | Application of Maximum Likelihood and Spectral Angle Mapping Classification Techniques to Evaluate Forest Fire Severity from UAV Multi-spectral Images in South Korea | High-resolution unmanned aerial vehicle (UAV) multi-spectral sensor images can provide valuable information for mapping forest areas that have recently been burned. In this study, we investigate the use of multi-spectral images captured with a UAV to evaluate burn severity in areas affected by forest fires in Gumi-si, South Korea. Fire classification was performed using two supervised learning algorithms, maximum likelihood (ML) and spectral angle mapper (SAM). Three spectral indices, namely, normalized difference vegetation index ( NDVI), RedEdge NDVI ( RE-NDVI), and the visible-band difference vegetation index (VDVI), were used to create burn severity thresholds in ML and SAM classifiers. The classification results indicated that ML has higher overall accuracy (80-89%, Kappa coefficient = 0.8) than SAM (44-52%, Kappa coefficients similar to 0.27) in identifying fire severity classes. The ML classifier showed higher accuracy for both unburned and crown fire classes, whereas the SAM classifier exhibited moderate accuracy for all classes. Most of the misclassification was identified between the unburned area and the low heat-damaged area. This research revealed that distinguishing between the unburned area and low heat-damaged area is the most challenging task in fire severity classification. Also, further investigation is required to improve the accuracy of fire severity classification from multi-spectral images. | Woo, Heesung; Acuna, Mauricio; Madurapperuma, Buddhika; Jung, Geonhwi; Woo, Choongshik; Park, Joowon | Kangwon Natl Univ, Coll Forest & Environm Sci, 1 Kangwondaehak Gil, Chuncheon Si 24341, Gangwon Do, South Korea; Univ Sunshine Coast, Forest Res Inst, Locked Bag 4, Maroochydore, Qld 4558, Australia; Humboldt State Univ, Dept Forestry & Wildland Resources, 1 Harpst St, Arcata, CA 95521 USA; Kyungpook Natl Univ, Sch Forest Sci & Landscape Architecture, 80 Daehakro, Daegu 41566, South Korea; Natl Inst Forest Sci, Forest Conservat Dept, Forest Disaster Management Div, 57 Hoegi Ro, Seoul 02445, South Korea | Madurapperuma, Buddhika/T-9987-2019; Woo, Heesung/AAG-4028-2020; Acuna, Mauricio/JOZ-5897-2023 | 57203973789; 55290631300; 55640200400; 57219031456; 55767522300; 55791550500 | whs1608@gmail.com;macuna@usc.edu.au;bdm280@humboldt.edu;alzaki3050@knu.ac.kr;woocs@korea.kr;jwnpark@gmail.com; | SENSORS AND MATERIALS | SENSOR MATER | 0914-4935 | 33 | 11 | SCIE | INSTRUMENTS & INSTRUMENTATION;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | 0.879 | 91.4 | 0.71 | 2025-07-30 | 10 | 11 | forest fire; UAV; remote sensing; accuracy assessment; machine learning | BURN SEVERITY; INDEXES; AIRCRAFT; DYNAMICS | Accuracy assessment; Forest fire; Machine learning; Remote sensing; UAV | Antennas; Deforestation; Fire hazards; Fires; Image classification; Image enhancement; Learning algorithms; Machine learning; Maximum likelihood; Spectroscopy; Unmanned aerial vehicles (UAV); Vegetation; Accuracy assessment; Burn Severity; Fire severity; Forest fires; Ma ximum likelihoods; Maximum-likelihood; Multispectral images; Remote-sensing; South Korea; Spectral angle mappers; Remote sensing | English | 2021 | 2021 | 10.18494/sam.2021.3365 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Establishment of iPSC (KRIBBi001-A) from CD34⁺ group O D-negative bone marrow blood | Human induced pluripotent stem cells with indefinite propagation in vitro provide a potential donor source of cells including erythroid cells for human therapy. Since group O D-negative (RhD) blood cells are considered as universal donors for transfusion, it is compelling to derive iPSC line from group O/RhD sample as a new cellular source to generate universal RBCs. The resulting iPSC line derived from group O/RhD somatic source showed typical features of pluripotent stem cells and could provide an unprecedented cellular tool to develop universal therapeutics for blood transfusion. | Kim, Jieun; Koh, Hyebin; Zhen, Xing; Lee, Dong-Seok; Ha, Hye-Yeong; Lee, Jong-Hee | Korea Res Inst Biosci & Biotechnol KRIBB, Natl Primate Res Ctr NPRC, Cheongju, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Futurist Anim Resource & Res Ctr FARRC, Cheongju, South Korea; Korea Univ Sci & Technol UST, KRIBB Sch Biosci, Dept Funct Genom, Daejeon, South Korea; Korea Natl Inst Hlth, Div Intractable Dis Res, Cheongju, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, Daegu, South Korea; Catholic Univ Korea, Coll Med, Dept Med Life Sci, Seoul, South Korea; Catholic Univ Korea, Coll Med, Dept Biomed & Hlth Sci, Seoul, South Korea | 57221729863; 57199507216; 57221725411; 57210068061; 54888945600; 57203736066 | jonglee@kribb.re.kr; | STEM CELL RESEARCH | STEM CELL RES | 1873-5061 | 1876-7753 | 51 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY;CELL & TISSUE ENGINEERING;CELL BIOLOGY | 2021 | 1.587 | 91.5 | 0.4 | 2025-07-30 | 6 | 5 | Bone Marrow; Cell Differentiation; Erythroid Cells; Humans; Induced Pluripotent Stem Cells; Pluripotent Stem Cells; CD34 antigen; cell surface marker; kruppel like factor 4; octamer transcription factor 4; organic cation transporter 3; rhesus D antigen; stage specific embryo antigen 4; tra 1 60 protein; transcription factor NANOG; transcription factor Sox2; unclassified drug; Article; blood group O; blood transfusion; bone marrow; controlled study; ectoderm; endoderm; gene expression; genetic profile; human; human cell; immunocytochemistry; induced pluripotent stem cell; mesoderm; normal human; pluripotent stem cell; priority journal; short tandem repeat; bone marrow; cell differentiation; erythroid cell; pluripotent stem cell | English | 2021 | 2021-03 | 10.1016/j.scr.2021.102199 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||

Here, we derived an iPSC line from a patient with reciprocal chromosome translocation, t(1;5)(p31.1;35.1), as a novel alternative model to identify clinical phenotypes induced by genetic instability. The resulting iPSC line generated from somatic cells with an existing instability showed representative characteristics of PSCs, and might serve as an unparalleled cellular resource for the development of a custom remedy. | Koh, Hyebin; Kwon, Soon-Young; Zhen, Xing; Ha, Hye-Yeong; Lee, Jong-Hee | Korea Res Inst Biosci & Biotechnol KRIBB, Natl Primate Res Ctr NPRC, Cheongju, South Korea; Korea Res Inst Biosci & Biotechnol KRIBB, Futurist Anim Resource & Res Ctr FARRC, Cheongju, South Korea; Univ Sci & Technol UST, KRIBB Sch Biosci, Dept Funct Genom, Daejeon, South Korea; Korea Natl Inst Hlth, Div Intractable Dis Res, Cheongju, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Nanosci & Nanotechnol, Daegu 41566, South Korea | 57199507216; 57312011500; 57221725411; 54888945600; 57203736066 | hahy0130@korea.kr;jonglee@kribb.re.kr; | STEM CELL RESEARCH | STEM CELL RES | 1873-5061 | 1876-7753 | 57 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY;CELL & TISSUE ENGINEERING;CELL BIOLOGY | 2021 | 1.587 | 91.5 | 0.08 | 2025-07-30 | 1 | 1 | CD33 antigen; CD34 antigen; cell surface marker; genomic DNA; hepatocyte nuclear factor 3beta; kruppel like factor 4; Myc protein; nestin; octamer transcription factor 4; protein TRA 1 60; receptor type tyrosine protein phosphatase C; stage specific embryo antigen 4; T box transcription factor; transcription factor NANOG; transcription factor PAX6; transcription factor Sox17; transcription factor Sox2; unclassified drug; adult; Article; bone marrow cell; cell differentiation; cell maturation; cell nuclear structure; cell reprogramming technique; cell structure; CFU counting; chromosomal instability; controlled study; cytoarchitecture; DNA determination; embryonic stem cell; erythrocyte; genotype; human; human cell; induced pluripotent stem cell; karyotype 46,XX; KRIBBi004-A cell line; phenotypic variation; pluripotent stem cell line; protein expression; reciprocal chromosome translocation; short tandem repeat; viral clearance | English | 2021 | 2021-12 | 10.1016/j.scr.2021.102587 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||

| ○ | ○ | Article | A New Indicator Predicting the Degree of Cord Shift After Posterior Decompression of Cervical Ossification of the Posterior Longitudinal Ligament Extended to the C2 Level and Its Clinical Usefulness | AIM: To evaluate the usefulness of the rostral line (R-line) as a new index for determining the degree of C2 lamina decompression in the context of ossification of the posterior longitudinal ligament (OPLL) extending to the C2 level. MATERIAL and METHODS: The R-line was devised based on the mechanism by which the cord is shifted backward following cervical posterior decompression. According to their R-line status, 36 patients with cervical OPLL extending to the C2 level were divided into two groups of R-line (+) and R-line (-) cases, where the R-line touched the upper half of the posterior C2 lamina in the R-line (+) group and the inferior half of the posterior C2 lamina in the R-line (-) group, respectively. RESULTS: Eighteen patients were classified as R-line (+) and 18 patients were classified as R-line (-). Total laminectomy of the C2 lamina was more common in the R-line (+) group, while dome-shape C2 laminectomy was more common in the R-line (-) group. All patients requiring reoperation were included in the R-line (+) group. Only the operation type showed a statistically significant difference according to the need for reoperation in the R-line (+) group; specifically, all patients who underwent reoperation in the R-line (+) group had dome-shape C2 laminectomy. It was determined that the risk factor for reoperation in the R-line (+) group was a history of dome-shape C2 laminectomy. CONCLUSION: If the R-line touches the upper half of the posterior C2 lamina, total decompression of the C2 lamina should be performed. | Lee, Byung-Jou; Lee, Subum; Jeon, Sang-Ryong; Roh, Sung Woo; Park, Jin Hoon | Inje Univ, Ilsan Paik Hosp, Neurosci & Radiosurg Hybrid Res Ctr, Coll Med,Dept Neurosurg, 170 Juwharo, Goyang 10380, Gyeonggi, South Korea; Kyungpook Natl Univ, Sch Med, Kyungpook Natl Univ Hosp, Dept Neurosurg, Daegu, South Korea; Univ Ulsan, Coll Med, Dept Neurosurg, Asan Med Ctr, 88 Olymp Ro 43 Gil, Seoul 05505, South Korea | Lee, Subum/AFQ-2764-2022 | 57203372544; 57193631061; 57203521670; 7004951729; 36898773700 | jhpark@amc.seoul.kr; | TURKISH NEUROSURGERY | TURK NEUROSURG | 1019-5149 | 31 | 6 | SCIE | CLINICAL NEUROLOGY;SURGERY | 2021 | 0.972 | 91.8 | 0.65 | 2025-07-30 | 6 | 5 | Axis; Cervical vertebra; Laminectomy; Ossification of the posterior longitudinal ligament; Posterior decompression; R-line | OPEN-DOOR LAMINOPLASTY; SPINAL-CORD; EXTENSOR MUSCULATURE; MYELOPATHY; ALIGNMENT; PRESERVATION; LAMINECTOMY; OUTCOMES; DRIFT; C7 | Axis; Cervical vertebra; Laminectomy; Ossification of the posterior longitudinal ligament; Posterior decompression; R-line | Cervical Vertebrae; Decompression, Surgical; Humans; Laminectomy; Longitudinal Ligaments; Ossification of Posterior Longitudinal Ligament; Osteogenesis; Retrospective Studies; Treatment Outcome; bone development; cervical vertebra; decompression surgery; diagnostic imaging; human; laminectomy; ligament calcinosis; posterior longitudinal ligament; retrospective study; treatment outcome | English | 2021 | 2021 | 10.5137/1019-5149.jtn.31668-20.1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Evaluating Operational Potential of UAV Transect Mapping for Wetland Vegetation Survey | There has been little research on data collection using Unmanned Aerial Vehicle (UAV) remote sensing in exploring wetland vegetation communities. The aim of this research was to integrate the concept of typical UAV remote sensing into in situ transect techniques. Transect sampling is commonly utilized to identify biological diversity and richness in vegetation communities. The Object-based Image Analysis was used to identify area-wide wetland vegetation that distinctively appears according to the UAV multispectral sensor's spectral characteristic. This study verified UAV transect mapping on wetland vegetation based on comparative evaluation between field survey and UAV transect method. This research offered an objective reference to UAV transect mapping's operational potential as the alternatives to traditional in-situ transect sampling in the coastal wetland. | Park, Seong-Il; Hwang, Young-Seok; Lee, Jung-Joo; Um, Jung-Sup | Kyungpook Natl Univ, Dept Spatial Informat, Daegu, South Korea; Kyungpook Natl Univ, Dept Climate Change, Daegu, South Korea; Kyungpook Natl Univ, Dept Geog, Daegu, South Korea | Um, Jung-Sup/F-5351-2018 | 57204267829; 57218585482; 57212448507; 35173565000 | jsaeom@knu.ac.kr; | JOURNAL OF COASTAL RESEARCH | J COASTAL RES | 0749-0208 | 1551-5036 | SCIE | ENVIRONMENTAL SCIENCES;GEOGRAPHY, PHYSICAL;GEOSCIENCES, MULTIDISCIPLINARY | 2021 | 1.11 | 91.8 | 0.45 | 2025-07-30 | 8 | 7 | Coastal wetland; UAV imagery; transect mapping; wetland vegetation survey | OCO-2 XCO2 | Coastal wetland; transect mapping; UAV imagery; wetland vegetation survey | Florida; field survey; image analysis; in situ measurement; mapping; plant community; remote sensing; research work; sampling; sensor; species diversity; species richness; unmanned vehicle | English | 2021 | 2021-가을 | 10.2112/jcr-si114-096.1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Effect of Sea Level Rise on Adjacent Land and the Resulting Land Value Assessment Method | This study aims to infer the possibility of inundation of coastal areas due to sea level rise caused by climate change. In addition, it seeks to present a necessary survey method and value calculation method to be reflected on the land value. To this end, GIS spatial analysis was performed using tidal observation data and flooding maps. The analysis of IPCC sea level rise assuming the worst-case scenario (Scenario 1) and the gradual-case scenario (Scenario 2) of the actual measurement data of the Busan Tide Observatory showed that 3.8%-5.5% of the total land in Haeundae-gu will be at risk of flooding within the next 100 years. Particularly, lands with a relatively high value at present are more vulnerable. If the method of calculating flood-prone areas presented in this study is introduced in the Government's Land Characteristic Evaluation and the standard land value for areas expected to be flooded is accurately assessed, then the economic loss and social confusion caused by future sea level rises can be prevented. | Joo, Seung-Min; Kim, Jun-Hyun | Korea Real Estate Board, Market Anal Res Off, Deagu, South Korea; Kyungpook Natl Univ, Dept Geog, Deagu, South Korea | Kim, Jonghwan/AAR-2815-2021 | 57292968900; 57201192219 | kamcho78@nate.com; | JOURNAL OF COASTAL RESEARCH | J COASTAL RES | 0749-0208 | 1551-5036 | SCIE | ENVIRONMENTAL SCIENCES;GEOGRAPHY, PHYSICAL;GEOSCIENCES, MULTIDISCIPLINARY | 2021 | 1.11 | 91.8 | 0.09 | 2025-07-30 | 1 | 1 | Annual sea level rise; land value; officially assessed land price; GIS; RS | TIDES | Annual sea level rise; GIS; land value; officially assessed land price; RS | Florida [United States]; Pusan [Pusan (ADS)]; Pusan [South Korea]; South Korea; United States; Florida; climate change; coastal zone; flooding; GIS; land evaluation; risk factor; sea level change | English | 2021 | 2021-가을 | 10.2112/jcr-si114-097.1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Significance of sonographically detected bladder debris in children less than 2 years with febrile urinary tract infection | Purpose To investigate the relationship between bladder debris found on renal and bladder ultrasonography (RBUS) and the first febrile urinary tract infection (UTI) episode in children under 2 years old. Methods We retrospectively reviewed the data of children aged <2 years with the first febrile UTI. We recorded bladder debris on RBUS and other findings (blood test, urinalysis, and urine culture). Other RBUS findings (renal pelvis debris, renal parenchymal change, wall thickening, and renal collecting system [RCS] dilatation) were recorded. Patients were divided into the debris (D) and non-D groups. Results Of 128 patients (boys: girls = 81:47, mean age = 5.6 +/- 4.2 months), 24 (18.8%) had bladder debris. The mean C-reactive protein (CRP) levels were higher in the D group (6.1 +/- 4.0 vs 4.3 +/- 3.5, P = .03). Twenty-one patients in the D group (87.5%) had hematuria (odds ratio = 3.706, 95% confidence interval = 1.035-13.267, P = .04). No significant differences were seen in the urine culture results between both groups. Significant associations were seen between bladder debris and other RBUS findings such as debris in renal pelvis, renal parenchymal change, and RCS wall thickening. Conclusion Bladder debris on RBUS is a common finding in children aged <2 years during the first febrile UTI. Bladder debris was related to higher CRP levels, hematuria and sonographic findings, but not to urine culture results. | You, Sun Kyoung; Lee, Jiwon M.; Lee, Jeong-Eun; Shin, Kyung Sook; Lee, So Mi; Cho, Hyun-Hae | Chungnam Natl Univ, Chungnam Natl Univ Hosp, Coll Med, Dept Radiol, 266 Munhwa Ro, Daejeon 35015, South Korea; Chungnam Natl Univ, Chungnam Natl Univ Hosp, Coll Med, Dept Pediat, Daejeon, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Radiol, Daegu, South Korea; Ewha Womans Univ, Dept Radiol, Coll Med, Seoul, South Korea; Ewha Womans Univ, Med Res Inst, Coll Med, Seoul, South Korea | Lee, Jeong Eun/R-8689-2019 | 56710939300; 57209882209; 57219538574; 7402410393; 56824903400; 56544900900 | sunkyou@cnuh.co.kr; | JOURNAL OF CLINICAL ULTRASOUND | J CLIN ULTRASOUND | 0091-2751 | 1097-0096 | 49 | 3 | SCIE | ACOUSTICS;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2021 | 0.869 | 92.2 | 0 | 2025-07-30 | 0 | 0 | bladder; pediatrics; ultrasonography; urinary tract infections | VESICOURETERAL REFLUX; PYELONEPHRITIS; PREDICTION; INFANTS; SYSTEM; WALL | bladder; pediatrics; ultrasonography; urinary tract infections | Child, Preschool; Female; Fever; Hematuria; Humans; Infant; Kidney; Kidney Pelvis; Male; Retrospective Studies; Ultrasonography; Urinary Tract Infections; complication; diagnostic imaging; echography; female; fever; hematuria; human; infant; kidney; kidney pelvis; male; pathology; preschool child; retrospective study; urinary tract infection | English | 2021 | 2021-03 | 10.1002/jcu.22964 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | On torsion in homology of finite connected quandles | It is known that the order of a finite quandle annihilates its reduced quandle homology and the torsion subgroup of its rack homology if the quandle is quasigroup. However, this does not hold in general if a quandle is connected. In this paper, we prove that under a certain condition, the reduced quandle homology and the torsion subgroup of the rack homology of a connected quandle are annihilated by the order of the inner automorphism group of the quandle. | Yang, Seung Yeop | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | 56589212300 | seungyeop.yang@knu.ac.kr; | JOURNAL OF KNOT THEORY AND ITS RAMIFICATIONS | J KNOT THEOR RAMIF | 0218-2165 | 1793-6527 | 30 | 14 | SCIE | MATHEMATICS | 2021 | 0.456 | 92.3 | 0 | 2025-07-30 | 0 | 0 | Connected quandle; quandle inner automorphism group; rack and quandle homology; torsion subgroup | BETTI NUMBERS; COHOMOLOGY; INVARIANT; RACK | Connected quandle; quandle inner automorphism group; rack and quandle homology; torsion subgroup | English | 2021 | 2021-12 | 10.1142/s0218216521410170 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | ALTERNATING MAGNETIC FIELD GENERATOR FOR THREE-DIMENSIONAL POSITION TRACKING OF MEDICAL TREATMENT EQUIPMENT FOR TRAINING | In recent years, the incidence of cardiovascular disease is high due to the aging population and westernization of dietary habits, what encourages researching new methods. Most cardiovascular procedures use the catheter. In the procedure using a catheter, a long time of training is required to lower the procedure risk. So, a medical training simulator is being developed. In the actual procedure, the position of the catheter is confirmed by a C-arm using X-ray, but there is a risk of over exposure to radiation if the X-ray device is used until training. To solve this problem, in previous studies, the position of the catheter was tracked using a permanent magnet. However, the method of permanent magnet has a high error value due to the shape of the external magnetic flux density and the interference of environmental magnetic field. In this paper, an alternating magnetic field generator is proposed for 3D position tracking of medical equipment for training. An electromagnet with an optimal shape was designed through finite element analysis. The designed electromagnet is implemented and tested to confirm the performance. Through the location tracking experiment, an equation to estimate the distance between the electromagnet and the Hall sensor in 3D space was derived by linear regression recursive method. Through the derived equation, it was possible to track the position of the electromagnet at any position in the 3D space. Unlike previous studies using permanent magnets, the proposed alternating magnetic field generator has an isotropic shape with an external magnetic flux density according to the same distance. So, it is possible to reduce errors in position and distance, and minimize the effect of environmental magnetic fields by using an alternating magnetic field. | Park, Min Gyu; Bang, Sang Kwang; Shin, Seong Hwal; Seong, Ki Woong; Lee, Jyung Hyun | Kyungpook Natl Univ, Grad Sch, Dept Med & Biol Engn, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Biomed Engn, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Engn, Daegu 41944, South Korea | Lee, Jaetae/AAR-3317-2021 | 57226021985; 57222732058; 57223140344; 23968197900; 8839783700 | ll20805ll@naver.com;banggwang1@naver.com;shs7417@gmail.com;seongkw@ee.knu.ac.kr;pung@knu.ac.kr; | JOURNAL OF MECHANICS IN MEDICINE AND BIOLOGY | J MECH MED BIOL | 0219-5194 | 1793-6810 | 21 | 05 | SCIE | BIOPHYSICS;ENGINEERING, BIOMEDICAL | 2021 | 0.883 | 92.4 | 0.07 | 2025-07-30 | 1 | 1 | Electromagnetic field generator; hall-effect; hall sensor; alternating magnetic field; position detecting | alternating magnetic field; Electromagnetic field generator; hall sensor; hall-effect; position detecting | Catheters; Electromagnets; Hall effect transducers; Magnetic flux; Permanent magnets; Tracking (position); X rays; Aging population; Alternating magnetic field; Cardio-vascular disease; Dimensional position; Environmental magnetic fields; Medical training simulator; Medical treatment; Recursive methods; Magnetic fields | English | 2021 | 2021-06 | 10.1142/s0219519421400273 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Optimal Microimplant Sites in the Mandibular Retromolar Area: Mesh Analysis of Cortical Bone Thickness and Density in CBCT Images | This study was performed to identify optimal microimplant sites in the mandibular retromolar area by measurement and analysis of cortical bone thickness and density. Forty-nine records of cone-beam computed tomography were selected from 173 patients. Invivo 5.2 software was used to measure the thickness and density of 25 sites on a mesh in the mandibular retromolar area. Pearson correlation, Spearman correlation, and binary logistic regression analyses were performed to explore correlations between retromolar measurements and patient characteristics. The LSD test was used to identify optimal microimplant sites in this area. One-way ANOVA, with post hoc SNK test, was used to compare optimal microimplant sites among the retromolar area, the distobuccal bone of the second molar, and a location between the first and second molars. The mean thickness and density of mandibular retromolar cortical bone were 2.35 +/- 0.76 mm and 530.49 +/- 188.83 HU, respectively. In the mandibular retromolar area, the thickness and density of cortical bone increased from the lingual to buccal sides, and from the distal to mesial. Among 25 sites, S5C1 had the greatest thickness and density; it exhibited greater thickness and density, compared with the distobuccal bone of the second molar and the site between the first and second molars. For distal uprighting of mesially tipped molars, we recommend placement of microimplants into the retromolar distobuccal site; for distalization of mandibular dentition, we recommend placement of microimplants into the retromolar mesiobuccal site (S5C1) or 2 mm from the mesial direction of the second molar distobuccal site (B). | Wang, Sen; Bang, Li; Park, Hyo-Sang | Kyungpook Natl Univ, Sch Dent, Dept Orthodont, 188-2,Samduk 2 Ga, Daegu, South Korea; Shanxi Med Univ, Sch Dent, Dept Orthodont, Taiyuan, Peoples R China | parkhs@knu.ac.kr; | INTERNATIONAL JOURNAL OF MORPHOLOGY | INT J MORPHOL | 0717-9502 | 0717-9367 | 39 | 3 | SCIE | ANATOMY & MORPHOLOGY | 2021 | 0.504 | 92.9 | 2 | Retromolar; Microimplant sites; Thickness; Density; Mesh analysis | MINI-IMPLANTS; FAILURE RATES; ALVEOLAR; DISTALIZATION | English | 2021 | 2021-06 | 바로가기 | 바로가기 | ||||||||||||
