| ○ | ○ | Proceedings Paper | Simulation of Self-driving System by implementing Digital Twin with GTA5 | Computer simulation based on digital twin is an essential process when designing self-driving cars. However, designing a simulation program that is exactly equivalent to real phenomena can be arduous and cost ineffective because many things have to be implemented. In this paper, we propose a method using the online game 'GTA5' as a groundwork for autonomous vehicle simulation. As 'GTA5' has a variety of well-implemented objects, people, and roads, it can be considered a suitable tool for simulation. By using OpenCV to capture the GTA5 game screen and analyzing images with YOLO and TensorFlow [1] based on Python, we can build quite an accurate object recognition system. This can lead to the writing of algorithms for object avoidance and lane recognition. Once these algorithms have been completed, vehicles in GTA5 can be controlled through codes composed of the basic functions of autonomous driving, such as collision avoidance and lane-departure prevention. | Yun, Heuijee; Park, Daejin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | Yun, Heuijee (Heejee)/GOJ-9000-2022 | 57222516795; 55463943600 | boltanut@knu.ac.kr; | 2021 INTERNATIONAL CONFERENCE ON ELECTRONICS, INFORMATION, AND COMMUNICATION (ICEIC) | 4.16 | 2025-07-30 | 10 | 21 | autonomous driving; simulation; digital twin; lane detection; game engine; OpenCV | Autonomous driving; Digital twin; Game engine; Lane detection; OpenCV; Simulation | Autonomous vehicles; Object recognition; Autonomous driving; Basic functions; Lane departure; Lane recognition; Object recognition systems; On-line games; Self drivings; Simulation program; Digital twin | English | 2021 | 2021 | 10.1109/iceic51217.2021.9369807 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | Simultaneous improvement of formaldehyde emission and adhesion of medium-density fiberboard bonded with low-molar ratio urea-formaldehyde resins modified with nanoclay | In wood-based composite panels, low-molar ratio (LMR) urea-formaldehyde (UF) resins usually result in reduced formaldehyde emission (FE) at the expense of poor adhesion. However, the FE and adhesion of medium-density fiberboard (MDF) bonded with LMR UF resins were both improved in this study. The modified LMR UF resins with transition metal ion-modified bentonite (TMI-BNT) nanoclay simultaneously improved the FE and adhesion of MDF panels. The modified LMR UF resins with 5% TMI-BNT resulted in a 37.1% FE reduction and 102.6% increase in the internal bonding (IB) strength of MDF panels. Furthermore, thickness swelling and water absorption also significantly decreased to 13.0% and 24.9%, respectively. These results imply that TMI-BNT modification of LMR UF resins could enhance the formation of a three-dimensional network rather than crystalline domains, resulting in improved cohesion. © 2021, Korean Society of Wood Science Technology.

| ○ | ○ | Article | Single microfluidic fuel cell with three fuels - formic acid, glucose and microbes: A comparative performance investigation | The development of microfluidic and nanofluidic devices is gaining remarkable attention due to the emphasis put on miniaturization of conventional energy conversion and storage processes. A microfluidic fuel cell can integrate flow of electrolytes, electrode-electrolyte interactions, and power generation in a microchannel. Such microfluidic fuel cells can be categorized on the basis of electrolytes and catalysts used for power generation. In this work, for the first time, a single microfluidic fuel cell was harnessed by using different fuels like glucose, microbes and formic acid. Herein, multi-walled carbon nanotubes (MWCNT) acted as electrode material, and performance investigations were carried out separately on the same microfluidic device for three different types of fuel cells (formic acid, microbial and enzymatic). The fabricated miniaturized microfluidic device was successfully used to harvest energy in microwatts from formic acid, microbes and glucose, without any metallic catalyst. The developed microfluidic fuel cells can maintain stable open-circuit voltage, which can be used for energizing various low-power portable devices or applications. | Sivakumar, Jayapiriya Umarani; Rao, Lanka Tata; Rewatkar, Prakash; Khan, Haroon; Dubey, Satish Kumar; Javed, Arshad; Kim, Gyu Man; Goel, Sanket | BITS Pilani, Dept Elect & Elect Engn, Hyderabad Campus, Hyderabad 500078, India; BITS Pilani, Dept Mech Engn, Hyderabad Campus, Hyderabad 500078, India; BITS Pilani, MEMS, Microfluid & Nanoelect MMNE Lab, Hyderabad Campus, Hyderabad 500078, India; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | Rewatkar, Prakash/AAH-1234-2020; Javid, Arshad/AAT-2423-2020; Goel, Sanket/A-2201-2010; TataRao, Lanka/KFT-1650-2024 | 57298363100; 57218125528; 57202059354; 14521310700; 57218665403; 57198262278; 55664733000; 7101999027 | sgoel@hyderabad.bits-pilani.ac.in; | JOURNAL OF ELECTROCHEMICAL SCIENCE AND ENGINEERING | J ELECTROCHEM SCI EN | 1847-9286 | 11 | 4 | ESCI | ELECTROCHEMISTRY | 2021 | N/A | 0.25 | 2025-07-30 | 3 | 4 | electrocatalysis; biocatalysis; chemical fuel; biofuel; portable devices | BIOFUEL CELL; ELECTRODES; ELECTROOXIDATION; PROGRESS; ENERGY; PAPER; PD | Biocatalysis; Biofuel; Chemical fuel; Electrocatalysis; Portable devices | English | 2021 | 2021 | 10.5599/jese.1092 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Proceedings Paper | Sliding mode approach for formation control of perturbed second-order autonomous unmanned systems | This paper proposes a sliding mode approach for leader-following formation control of perturbed second-order autonomous unmanned systems (AUSs) under directed topology. The leader velocity is assumed to be constant. The formation controller performs two objectives: (i) it obtains the formation control of all the followers, (ii) it achieves the velocity consensus of all the followers. Using Lyapunov stability theory, we have presented the finite-time convergence of sliding surface and asymptotic stability of the closed-loop system. Finally, a numerical example with comparative results demonstrates the efficacy of the proposed method.

| ○ | Book chapter | Smartphone-Based Paper Microfluidic Immunoassay of Salmonella and E. coli | Previous studies from our lab have created a simple procedure for single-cell count of bacteria on a paper chip platform using optical detection from a smartphone. The procedure and steps employed are outlined along with the lessons learned and details of certain steps and how the design was optimized. Smartphone optical detection is easy to use, low cost, and potentially field deployable, which can be useful for early and rapid detection of pathogens. Smartphone imaging of a paper microfluidic chip preloaded with antibody-conjugated particles provides an adaptable platform for detection of different bacterial targets. The paper microfluidic chip was fabricated with a multichannel design. Each channel was preloaded with either a negative control of bovine serum albumin (BSA) conjugated particles, anti-Salmonella Typhimurium-conjugated particles with varying amounts (to cover different ranges of assay), or anti-Escherichia coli-conjugated particles. Samples were introduced to the paper microfluidic chip using pipetting. Antigens of Salmonella Typhimurium traveled through the channel by capillary action confined within the paper fibers surrounded by the hydrophobic barrier. The paper channel was observed to act as a filter for unwanted particles and contaminants found in field samples. Serial dilutions of known concentrations of bacterial targets were also tested using this procedure to construct a standard curve prior to the assays. The antibody-conjugated particles were able to immunoagglutinate which was quantified through evaluation of Mie scatter intensity. This Mie scattering was quantified in images taken with a smartphone at an optimized angle and distance. Mie scatter simulation provided a method of optimizing the experimental setup and could translate easily to other types of target sample matrices. A smartphone application was developed to help the user position the smartphone optimally in relation to the paper microfluidic chip. The application integrated both image capturing capability and a simple image processing algorithm that calculated bacteria concentrations. The detection limit was at a single-cell level with a total assay time ranging from 90 to less than 60 s depending on the target. © 2021, Springer Science+Business Media, LLC, part of Springer Nature. | Dieckhaus, Laurel; Park, Tu San; Yoon, Jeong-Yeol | Department of Biomedical Engineering, The University of Arizona, Tucson, AZ, United States; Department of Bio-Industrial Machinery Engineering, Kyungpook National University, Daegu, South Korea; Department of Biomedical Engineering, The University of Arizona, Tucson, AZ, United States, Department of Biosystems Engineering, The University of Arizona, Tucson, AZ, United States | 57218865176; 57202780408; 7403587817 | jyyoon@email.arizona.edu; | Methods in Molecular Biology | 1064-3745 | 2182 | 1.43 | 2025-07-30 | 6 | Immunoagglutination; Immunoassay; Paper microfluidics; Salmonella; Smartphone | Escherichia coli; Immunoassay; Lab-On-A-Chip Devices; Microfluidic Analytical Techniques; Microfluidics; Salmonella typhimurium; Smartphone; antibody conjugate; bacterial antigen; bovine serum albumin; controlled study; Entamoeba coli; hydrophobicity; imaging algorithm; immunoassay; limit of detection; microfluidic analysis; nonhuman; printing; Salmonella enterica serovar Typhimurium; simulation; surface property; Escherichia coli; immunoassay; immunology; lab on a chip; microfluidics; procedures; Salmonella enterica serovar Typhimurium; smartphone | English | Final | 2021 | 10.1007/978-1-0716-0791-6_9 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Software Tools to Calculate Moist Air Properties for Psychrometric Process Analysis | Purpose: This study aimed to develop software tools for psychrometric education and analyzed the accuracy of used models. Methods: Two psychrometric software tools were developed. One tool is based on an ASABE standard and calculates moist air properties and displays state point migration on a psychrometric chart pane according to user input sequences. The other tool is mainly based on ASHRAE equations with a few modifications to improve accuracy. It calculates moist air properties when two property values out of nine are provided in 1 out of 13 parameter combinations. The accuracy of the tools is addressed at 15 selected state points referring to a real gas model for a temperature range of 5–50 °C. Results: The first tool showed an accuracy of 99.12%. However, at an extremely cool and dry condition (5 °C and 2.02% RH), it failed because of extrapolation beyond the applicable range of saturation line equation. The second tool showed an accuracy of 99.68%. Among the situations of input properties, the best performance was obtained with an accuracy of 99.85% wherein dry-bulb and dew-point temperatures are provided. When dry-bulb temperature and specific volume are provided, the lowest accuracy of 99.20% was obtained. Conclusions: Both tools can be used in air-conditioning and psychrometric courses for analyzing and visualizing moist air processes with sufficient accuracy. © 2021, The Korean Society for Agricultural Machinery. | Bae, Yeonghwan; Koo, Youngmo | Department of Bio-Industrial Machinery Engineering, Sunchon National University, Jeollanamdo, Suncheon, 57922, South Korea; School of Agricultural, Civil, and Bio-Industrial Machinery Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea | 26321407200; 57197976008 | ymkoo@knu.ac.kr; | Journal of Biosystems Engineering | 1738-1266 | 46 | 4 | 0.21 | 2025-07-30 | 2 | Moist air; Property estimation; Psychrometric chart; Psychrometrics | Air conditioning; Air properties; Input sequence; Moist air; Process analysis; Property estimation; Psychrometric charts; Psychrometrics; Software-tools; State points; User input; Computer software | English | Final | 2021 | 10.1007/s42853-021-00121-x | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Article | Some Extensions of Rings with Noetherian Spectrum | In this paper, we study rings with Noetherian spectrum, rings with locally Noetherian spectrum and rings with t-locally Noetherian spectrum in terms of the polynomial ring, the Serre's conjecture ring, the Nagata ring and the t-Nagata ring. In fact, we show that a commutative ring R with identity has Noetherian spectrum if and only if the Serre's conjecture ring R[X](U) has Noetherian spectrum, if and only if the Nagata ring R[X](N) has Noetherian spectrum. We also prove that an integral domain D has locally Noetherian spectrum if and only if the Nagata ring D[X](N) has locally Noetherian spectrum. Finally, we show that an integral domain D has t-locally Noetherian spectrum if and only if the polynomial ring D[X] has t-locally Noetherian spectrum, if and only if the t-Nagata ring D[X](Nv) has (t-)locally Noetherian spectrum. | Park, Min Ji; Lim, Jung Wook | Hannam Univ, Coll Life Sci & Nano Technol, Dept Math, Daejeon 34430, South Korea; Kyungpook Natl Univ, Dept Math, Coll Nat Sci, Daegu 41566, South Korea | 57221553887; 35766755400 | mjpark5764@gmail.com;jwlim@knu.ac.kr; | KYUNGPOOK MATHEMATICAL JOURNAL | KYUNGPOOK MATH J | 1225-6951 | 0454-8124 | 61 | 3 | ESCI | MATHEMATICS | 2021 | N/A | 0.17 | 2025-07-30 | 1 | 1 | radically finite ideal; Noetherian spectrum; (t-)locally Noetherian spectrum; Serre's conjecture ring; (t-)Nagata ring; finite (t-)character | DOMAINS | (t-)locally Noetherian spectrum; (t-)Nagata ring; finite (t-)character; Noetherian spectrum; radically finite ideal; Serre’s conjecture ring | English | 2021 | 2021-09 | 10.5666/kmj.2021.61.3.487 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | Review | Some living eukaryotes during and after scanning electron microscopy | Electron microscopy (EM) is an essential imaging method in biological sciences. Since biological specimens are exposed to radiation and vacuum conditions during EM observations, they die due to chemical bond breakage and desiccation. However, some organisms belonging to the taxa of bacteria, fungi, plants, and animals (including beetles, ticks, and tardigrades) have been reported to survive hostile scanning EM (SEM) conditions since the onset of EM. The surviving organisms were observed (i) without chemical fixation, (ii) after mounting to a precooled cold stage, (iii) using cryo-SEM, or (iv) after coating with a thin polymer layer, respectively. Combined use of these techniques may provide a better condition for preservation and live imaging of multicellular organisms for a long time beyond live-cell EM. © 2021, The Author(s). | Kim, Ki Woo | Department of Ecology and Environmental System, Kyungpook National University, Sangju, 37224, South Korea | 57201369889 | kiwoo@knu.ac.kr; | Applied Microscopy | 2287-5123 | 51 | 1 | 0.03 | 2025-07-30 | 1 | Desiccation; Radiation; Scanning electron microscopy; Vacuum | Biology; Scanning electron microscopy; Biological science; Biological specimens; Chemical bond breakage; Chemical fixation; Condition; Exposed to; Imaging method; Radiation condition; Stage III; Vacuum condition; Driers (materials) | English | Final | 2021 | 10.1186/s42649-021-00065-8 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Article | Sonodegradation of amitriptyline and ibuprofen in the presence of Ti3C2Tx MXene | This study, which investigated the sonodegradation of selected pharmaceutical active compounds (PhACs) (amitriptyline (AMT) and ibuprofen (IBP)) with MXene, was carried out in an aqueous solution. To investigate the practicality of the degradation process, the experiments were conducted in various water quality conditions, including pH, temperature, natural organic matter, and ionic strength. Based on the experimental results, the produced hydrogen peroxide, which could be a representative of the produced OH radicals, was a vital factor that affected the degradation performance of both PhACs. To confirm the importance of OH radicals, the effect of a OH radical promoter (H2O2) and scavenger (t-BuOH) was also studied. In addition, the synergism between ultrasonication (US) and MXene was evaluated with the rate constants of US only, MXene only, and a US/MXene combined system. Mineralization of the PhACs was also investigated, and removal of AMT was higher than that of IBP, which could be attributed to the physicochemical properties of the compounds and enhanced adsorption by the well-dispersed MXene. Overall, utilization of MXene by means of ultrasonication could enhance the removal performance of PhACs in water. | Jeon, Minjung; Jun, Byung-Moon; Kim, Sewoon; Cho, Jaeweon; Park, Chang Min; Choong, Choe Earn; Jang, Min; Yoon, Yeomin | Univ South Carolina, Dept Civil & Environm Engn, 300 Main St, Columbia, SC 29208 USA; Korea Atom Energy Res Inst KAERI, Radwaste Management Ctr, 111 Daedeok Daero 989beon Gil, Daejeon 34057, South Korea; Ulsan Natl Inst Sci & Technol, Sch Urban & Environm Engn, UNIST Gil 50, Ulsan, South Korea; Kyungpook Natl Univ, Dept Environm Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kwangwoon Univ, Dept Environm Engn, 447-1 Wolgye Dong, Seoul 01897, South Korea | ; Choong, Choe Earn/J-3005-2016; Jang, Min/J-2230-2012; Jun, Byung-Moon/Y-2134-2019; Yoon, Yeomin/KDP-2253-2024; Park, Chang Min/CAA-8506-2022 | 56161129800; 55326699900; 57201422323; 7403536101; 57209588953; 57200944393; 36762550700; 7402126688 | jeejaejang@gmail.com;yoony@cec.sc.edu; | JOURNAL OF HAZARDOUS MATERIALS LETTERS | 2666-9110 | 2 | 0.59 | 2025-07-30 | 11 | 15 | Pharmaceuticals; Sonodegradation; Adsorption; Water treatment | PERSONAL CARE PRODUCTS; ENDOCRINE DISRUPTING COMPOUNDS; SUSPENDED PARTICULATE MATTER; WALLED CARBON NANOTUBES; WASTE-WATER; SONOCATALYTIC DEGRADATION; ULTRASONIC DEGRADATION; TREATMENT PLANTS; DRINKING-WATER; ILLICIT DRUGS | Adsorption; Pharmaceuticals; Sonodegradation; Ti<sub>3</sub>C<sub>2</sub>T<sub>X</sub> MXene; Water treatment | English | 2021 | 2021-11 | 10.1016/j.hazl.2021.100028 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Sound processor replacement in patients with cochlear implant: Analysis of a 30-year single-institutional experience | Background and Objectives The purpose of this study is to investigate the replacement of external sound processors and to help understand the economic burden experienced from cochlear implant users. Subjects and Method Among the 500 cases of cochlear implant surgery from 1992 to 2019, 336 cases from 311 patients who had used a cochlear implant for more than 1 year were enrolled. The period of cochlear implant use, replacement of the sound processor, the number, method, and reason of replacements were examined. Results One hundred sixty cases (47.62%) replaced the sound processor at least once. There were a total of 213 replacements made in 160 cases. The most common reason for replacing the sound processors was because it could not be repaired (71 replacements, 33.33%), with their period of use being an average of 12 years. The most common replacement method of the sound processors was by purchasing with medical insurance benefits (100 replacements, 46.95%), with the usage period being an average of 11 years and 4 months. Conclusion Cochlear implant users replaced the sound processor for various reasons and the period of using one sound processor was relatively short. About half of all replacement cases were made by applying for medical insurance benefits. Others purchased directly through a sales company and paid a relatively high cost. Therefore, it is necessary to expand the medical insurance for external sound processor of cochlear implants to include exchange times considering the economic burden of cochlear implant users. © 2021 Korean Academy of Audiology.

| ○ | Article | Spatial information-based fire risk evaluation in dense obsolete building areas for smart city development: A case study of Daegu metropolitan city | Smart cities, whether newly developed or existing, should enable the protection of citizens from various types of disasters. With regard to fire safety, artificial intelligence algorithms that evaluate fire prone facilities based on spatial information are applied to smart cities. This study analyzed the applicability of fire risk evaluation technologies based on spatial information as core technologies for smart cities. To this end, a fire risk evaluation based on spatial information was performed in an area designated as a target zone for a housing environment improvement project in Daegu, South Korea. The evaluation involved the application of a main fire risk evaluation system consisting of 12 evaluation items. Data was obtained using drones, orthophotos, numerical maps, and building ledgers; the obtained data and a GIS-based fire risk evaluation platform were used to evaluate the level of fire risk in the target area. The evaluation result showed that fire risks according to the unit of a building or a district were effectively evaluated by the application of the spatial information-based fire risk evaluation technology.

The processing parameters like puree load (0.4-0.6 g/cm(2)), total soluble solid (20-30 degrees B), oven temperature (60-80 degrees C), and microwave power level (100-300 W) were optimised for a superior textural attribute (hardness) primitive drying method like sun drying, industrially practiced modern methods like hot air oven drying and microwave drying and cutting-edge drying technique like freeze-drying. Response surface methodology and artificial neural network technique were adapted to model these drying procedures by considering the central composite design. The mathematical operations guiding to describe the model were studied. Being an imperative parameter colour quantification is essential for food industries. Current research employs microwave drying to produce mango leather with colour quantification approach. The L, 'a' and 'b' values of the product have been measured by Hunter Lab colorimeter and by digital image analysis, to determine the chromatic view harmonious to human vision. The relative analysis of colour measurement through these two techniques has been studied. | Sarkar, Tanmay; Salauddin, Molla; Choudhury, Tanupriya; Um, Jung-Sup; Pati, Siddhartha; Hazra, Sudipta Kumar; Chakraborty, Runu | Jadavpur Univ, Fac Engn & Technol, Dept Food Technol & Biochem Engn, Kolkata 700032, India; Govt West Bengal, Malda Polytech, West Bengal State Council Tech Educ, Malda 732102, India; Univ Petr & Energy Studies, Sch Comp Sci, Dehra Dun, Uttarakhand, India; Kyungpook Natl Univ, Dept Geog, Daegu, South Korea; Univ Malaysia Terengganu, Inst Trop Biodivers & Sustainable Dev, Terengganu 21030, Malaysia; Khallikote Univ, Ctr Excellence, Berhampur 761008, Odisha, India; Assoc Biodivers Conservat & Res ABC, Res Div, Balasore 745001, Odisha, India | Sarkar, Tanmay/AAL-7513-2021; Um, Jung-Sup/F-5351-2018; SALAUDDIN, MOLLA/AAD-3533-2022; pati, Siddhartha/Y-1752-2019; Choudhury, Tanupriya/AAB-8947-2020 | 57203373596; 57216389494; 57193140084; 35173565000; 57405230600; 57216397157; 7202348973 | crunu@hotmail.com; | SPATIAL INFORMATION RESEARCH | SPAT INF RES | 2366-3286 | 2366-3294 | 29 | 4 | ESCI | REMOTE SENSING | 2021 | N/A | 1.2 | 2025-07-30 | 12 | 19 | Response surface methodology; Artificial neural network; Drying; Digital image; Hunter colorimeter | Artificial neural network; Digital image; Drying; Hunter colorimeter; Response surface methodology | Color; Colorimetry; Drying; Fruits; Image analysis; Leather; Ovens; Surface properties; Color estimation; Digital image; Digital image analysis; Hunter colorimeter; Image analysis techniques; Leather production; Microwave drying; Processing parameters; Response-surface methodology; Spatial optimization; Neural networks | English | 2021 | 2021-08 | 10.1007/s41324-020-00377-z | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Spiking Neural Network (SNN) for Crop Yield Prediction | Crop yield prediction focuses mostly on agricultural research, which have an enormous impact on taking decisions for example import-export, price, along with crop management. Accurate forecasting with well-Timed projections is critical, but it is a challenging undertaking owing to various complicated aspects. There are few examples of crops that can be utilized to forecast crop yields like Wheat, peas, rice, pulses, tea, sugar cane, green houses, cotton, soybeans, and corn. Agriculture needs massive datasets and awareness practices. Meteorological conditions, components of soil, management methods, genotype, and their connections are utilized to predict corn yield. Optimal crop growth frequently requires a detailed knowledge of the operational relationships among yield and these interaction parameters, that needs large datasets and difficult algorithms to demonstrate. Several Machine Learning models, Deep Learning models, and Artificial Neural Network methods are used to forecast. Convolutional Neural Networks (CNN), Spiking Neural Networks (SNN), and Recurrent Neural Networks (RNN) are used to estimate corn production (RNN). By integrating RNN and SNN models, each model functioning was improved. © 2021 IEEE. | Gul, Malik Urfa; John Pratheep, K.; Junaid, M.; Paul, Anand | Kyungpook National University, Department of Computer Science and Engineering, Daegu, South Korea; Design Engineer, Intel, Santa Clara, CA, United States; Kyungpook National University, Department of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, Department of Computer Science and Engineering, Daegu, South Korea | 58087464900; 57485834500; 57526794200; 56650522400 | paul.editor@gmail.com; | 2021 9th International Conference on Orange Technology, ICOT 2021 | 1.77 | 2025-07-30 | 5 | crop yield; prediction; recurrent neural networks (RNN); spiking neural networks (SNN) | Convolutional neural networks; Crops; Large dataset; Recurrent neural networks; Sugar cane; Agricultural research; Crop managements; Crop yield; Export price; Green house; Massive data sets; Neural-networks; Recurrent neural network; Spiking neural network; Yield prediction; Forecasting | English | Final | 2021 | 10.1109/icot54518.2021.9680618 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | ○ | Article | Spindle cell oncocytoma of the sella turcica with anaplastic features and rapid progression in short-term follow-up: a case report with proposal of distinctive radiologic features | We present a rare case of spindle cell oncocytoma (SCO) of the sella turcica with malignant histologic features and rapid progression. A 42-year-old woman experienced bilateral blurred vision and was preoperatively misdiagnosed as having a pituitary macroadenoma on magnetic resonance imaging. After surgery, SCO was diagnosed by the histopathologic features of interlacing fascicles of spindle tumor cells with finely granular, eosinophilic cytoplasm. Focal anaplastic changes and necrosis were present. Immunohistochemically, the tumor cells were positive for vimentin, epithelial membrane antigen, S-100, galectin-3, and thyroid transcription factor 1. Four months later, the tumor had progressed, and second surgery with adjuvant radiotherapy was performed; the patients remains under observation. In this report, we proposed distinctive radiologic features for differential diagnosis between SCO and other pituitary tumors. | Kim, Dong Ja; Lee, SangHan; Kim, Mee-Seon; Hwang, Jeong-Hyun; Hahm, Myong Hun | Kyungpook Natl Univ, Sch Med, Dept Forens Med, Korea, South Korea; Def Inst Forens Sci, Dept Forens Med, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Pathol, Korea, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Korea, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, 680 Gukchaebosang Ro, Daegu 41944, South Korea | 57282881600; 57223972498; 56123006700; 7403896906; 56015548700 | hammh7@gmail.com; | JOURNAL OF PATHOLOGY AND TRANSLATIONAL MEDICINE | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 55 | 3 | ESCI | PATHOLOGY | 2021 | N/A | 0.13 | 2025-07-30 | 2 | 2 | Oncocytoma; Sella turcica; Neoplasms; Progression; Radiology | ADENOHYPOPHYSIS; PITUITARY; TUMORS | Neoplasms; Oncocytoma; Progression; Radiology; Sella turcica | epithelial membrane antigen; galectin 3; homeobox protein Nkx 2.1; protein S 100; vimentin; adjuvant radiotherapy; adult; Article; blurred vision; cancer diagnosis; cancer radiotherapy; cancer surgery; case report; clinical article; craniopharyngioma; cytoplasm; diagnostic error; differential diagnosis; female; follow up; headache; hemianopia; histopathology; human; human tissue; hypophysis; hypophysis adenoma; hypophysis tumor; immunohistochemistry; macroadenoma; nuclear magnetic resonance imaging; oncocytoma; optic chiasm; preoperative evaluation; sella turcica; spindle cell | English | 2021 | 2021-05 | 10.4132/jptm.2021.01.27 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
