| ○ | ○ | Article | Error Rate Performance Analysis of M-ary Coherent FSO Communications with Spatial Diversity in Strong Atmospheric Turbulence | In this letter, we analyze the error rate performance of M-ary coherent free-space optical (FSO) communications under strong atmospheric turbulence. Specifically, we derive the exact error rates for M-ary phase shift keying (MPSK) and M-ary quadrature amplitude modulation (MQAM) based on moment-generating function (MGF) with negative exponential distributed turbulence, where maximum ratio combining (MRC) receiver is adopted to mitigate the turbulence effects. Additionally, by evaluating the asymptotic error rate in high signal-to-noise ratio (SNR) regime, it is possible to effectively investigate and predict the error rate performance for various system configurations. The accuracy and the effectiveness of our theoretical analyses are verified via numerical results. | Kang, Jinkyu; Jeong, Seongah; Lee, Hoojin | Myongji Univ, Dept Informat & Commun Engn, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea; Hansung Univ, Div IT Convergence Engn, Seoul, South Korea | Jeong, Seongah/ABW-7285-2022; Kang, Joonhyuk/C-1771-2011; Jeong, Seongah/I-2863-2017 | 56283062100; 55210226900; 57215913990 | hjlee@hansung.ac.kr; | IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES | IEICE T FUND ELECTR | 0916-8508 | 1745-1337 | E105A | 5 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2022 | 0.5 | 96.9 | 0 | 2025-06-25 | 0 | 0 | free-space optical (FSO); error rate performance; strong atmospheric turbulence | SPACE OPTICAL COMMUNICATION; SYSTEMS | error rate performance; free-space optical (FSO); strong atmospheric turbulence | Atmospheric thermodynamics; Atmospheric turbulence; Optical communication; Phase shift keying; Quadrature amplitude modulation; Signal to noise ratio; Error rate; Error rate performance; Free Space Optical communication; Free-space optical; M-ary phase shift keying; Mary quadrature amplitude modulations (M-QAM); Performances analysis; Spatial diversity; Strong atmospheric turbulence; Errors | English | 2022 | 2022-05 | 10.1587/transfun.2021eal2062 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | Article | On the Window Choice for Two DFT Magnitude-Based Frequency Estimation Methods | We analyze the effect of window choice on the zero-padding method and corrected quadratically interpolated fast Fourier transform using a harmonic signal in noise at both high and low signal-to-noise ratios (SNRs) on a theoretical basis. Then, we validate the theoretical analysis using simulations. The theoretical analysis and simulation results using four traditional window functions show that the optimal window is determined depending on the SNR; the estimation errors are the smallest for the rectangular window at low SNR, the Hamming and Hanning windows at mid SNR, and the Blackman window at high SNR. In addition, we analyze the simulation results using the signal-to-noise floor ratio, which appears to be more effective than the conventional SNR in determining the optimal window. | Pang, Hee-Suk; Lee, Seokjin | Sejong Univ, Dept Elect Engn, Neungdong Ro 209, Seoul, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daehak Ro 80, Daegu 41566, South Korea | sjlee6@knu.ac.kr; | IEICE TRANSACTIONS ON FUNDAMENTALS OF ELECTRONICS COMMUNICATIONS AND COMPUTER SCIENCES | IEICE T FUND ELECTR | 0916-8508 | 1745-1337 | E105A | 1 | SCIE | COMPUTER SCIENCE, HARDWARE & ARCHITECTURE;COMPUTER SCIENCE, INFORMATION SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC | 2022 | 0.5 | 96.9 | 0 | window choice; harmonic signal; signal-to-noise ratio; window function; signal-to-noise floor ratio | VOICE | English | 2022 | 2022-01 | 10.1587/transfun.2021eal2026 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Fabrication and Performances of Recessed Gate AlGaN/GaN MOSFETs with Si3N4/TiO2 Stacked Dual Gate Dielectric | In this paper, a recessed gate AlGaN/GaN metal-oxide-semiconductor field-effect-transistor (M-OSFET) with Si3N4/TiO2 stacked dual gate dielectric was proposed and fabricated to improve the current drivability. Normally-off operation with a Vth of 1.81 V was obtained using a Cl-2-based gate recess etching process. Dual gate dielectric technology was used to improve the current characteristics that can be degraded by damage resulting from gate recess etching. Compared to the single gate dielectric (Si3N4 = 30 nm)-based device, the ID,max and gm of the dual gate dielectric (Si3N4/TiO2 = 10/20 nm)-based device were improved by 292% and 195%, respectively. Moreover, the Ron and SS were improved by 62% and 68%, respectively. Breakdown voltage decreased by 1.4%, but there was minor difference. Therefore, the technique of depositing Si3N4 on GaN and then stacking high-k TiO2 can improve the current characteristics by increasing the capacitance through a simple process. As such, the recessed gate AlGaN/GaN MOSFETs with Si3N4/TiO2 stacked dual gate dielectric has the potential for high-efficiency power devices. | An, Hee Dae; Min, So Ra; Lee, Sang Ho; Park, Jin; Kim, Geon Uk; Yoon, Young Jun; Seo, Jae Hwa; Cho, Min Su; Jang, Jaewon; Bae, Jin-Hyuk; Lee, Sin-Hyung; Kang, In Man | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 702201, South Korea; Korea Atom Energy Res Inst, Korea Multipurpose Accelerator Complex, Gyeongju 38180, South Korea; Korea Electrotechnol Res Inst, Power Semicond Res Ctr, Chang Won 51543, South Korea; DB HiTek, 90 Sudo Ro, Bucheon Si, Gyeongg Do, South Korea | Lee, Sin-Hyung/ABD-6425-2022; Seo, Jae Hwa/KYP-7367-2024; Lee, Sang Ho/MCX-8396-2025 | 57539074100; 57671524600; 57416738400; 57376422900; 57727029200; 57218864885; 58837410100; 59815822100; 57194107504; 35326180700; 57226880204; 7203062678 | imkang@ee.knu.ac.kr; | JOURNAL OF SEMICONDUCTOR TECHNOLOGY AND SCIENCE | J SEMICOND TECH SCI | 1598-1657 | 2233-4866 | 22 | 2 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC;PHYSICS, APPLIED | 2022 | 0.4 | 98.4 | 0.16 | 2025-06-25 | 2 | 2 | GaN; AlGaN; dual gate dielectric; silicon nitride (Si < sub > 3 <; sub > N < sub > 4 <; sub >); titanium dioxide (TiO < sub > 2 <; sub >); normally-off; recessed gate technique | HIGH-THRESHOLD-VOLTAGE; MIS-HEMT; MODE; OPERATION; HFET; SIN | AlGaN; dual gate dielectric; GaN; normally-off; recessed gate technique; silicon nitride (Si<sub>3</sub>N<sub>4</sub>); titanium dioxide (TiO<sub>2</sub>) | Aluminum gallium nitride; Capacitance; Chlorine compounds; Etching; Fabrication; Gallium nitride; Gate dielectrics; High electron mobility transistors; High-k dielectric; III-V semiconductors; Metals; MOS devices; MOSFET devices; Oxide semiconductors; Semiconductor alloys; Wide band gap semiconductors; Current characteristic; Dual gate dielectric; Dual gates; Gate recess etching; MOSFETs; Normally off; Recessed gate; Recessed gate technique; Silicon nitride (si3N4); Titania dioxide (TiO2); Titanium dioxide | English | 2022 | 2022-04 | 10.5573/jsts.2022.22.2.105 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Molar uprighting using a newly designed segmental wire: a case report | The ectopic eruption path of a permanent molar can cause incomplete emergence through interference by an adjacent tooth, early loss of a primary molar, or an arch length discrepancy. It is clinically important to determine the appropriate appliance that may easily be placed for the considered application of a molar corrective force. A newly designed appliance is introduced for the distal uprighting of an ectopically erupting molar and supported by two case presentations. The current technique of using a segmental wire incorporating double-sided hooks may easily and effectively resolve this problem. | Bae, Seong-Min; Kim, Ho-Jin | Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea | 7202714284; 57200084686 | anchor94@gmail.com;hojinkim@knu.ac.kr; | AUSTRALASIAN ORTHODONTIC JOURNAL | AUSTRALAS ORTHOD J | 2207-7472 | 2207-7480 | 38 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2022 | 0.4 | 98.4 | 0 | 2025-06-25 | 1 | 1 | 1ST PERMANENT MOLAR; ECTOPIC ERUPTION; PREVALENCE; TEETH | English | 2022 | 2022-01-01 | 10.2478/aoj-2022-0027 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Characterization of the complete chloroplast genome sequence of Potentilla gageodoensis (rosaceae), endemic to the continental islands of Korea | This study reports the complete chloroplast genome sequence of a continental island endemic, Potentilla gageodoensis. The total plastome size was 156,397 bp, comprising one large single-copy (LSC; 85,768 bp), one small single-copy (SSC; 18,589 bp), and two inverted repeat (IR) regions (IRa and IRb, each with 26,020 bp). The overall GC content was 36.92%, and the plastome contained 131 genes, comprising 84 protein-coding genes with two pseudogenes (infA and ycf1), 37 transfer RNA genes, and eight ribosomal RNA genes. Phylogenetic analysis performed using 27 representative Rosoideae plastomes suggests that the genus Potentilla is not monophyletic and that P. gageodoensis is sister to the clade containing four taxa of Potentilla (P. freyniana, P. freyniana var. chejuensis, P. stolonifera, and P. stolonifera var. quelpaertensis). The present study reveals the taxonomic distinction of P. gageodoensis from its congeneric species in Korea and the plastome sequence obtained from this study can be used to study phylogenetic relationships and taxonomic status. | Kim, Seon-Hee; Shukhertei, Ariun; Yang, JiYoung; Kim, Seung-Chul | Sungkyunkwan Univ, Dept Biol Sci, 2066 Seobu Ro, Suwon 16419, South Korea; Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Daegu, South Korea | Kim, Seung-Chul/AAR-6157-2020 | 57196226213; 57192893911; 55193226000; 57214983739 | sonchus96@skku.edu; | MITOCHONDRIAL DNA PART B-RESOURCES | MITOCHONDRIAL DNA B | 2380-2359 | 7 | 4 | SCIE | GENETICS & HEREDITY | 2022 | 0.5 | 98.5 | 0.09 | 2025-06-25 | 1 | 1 | Complete chloroplast genome; phylogenomic analysis; Potentilla gageodoensis; Rosaceae | Complete chloroplast genome; phylogenomic analysis; Potentilla gageodoensis; Rosaceae | English | 2022 | 2022-04-03 | 10.1080/23802359.2022.2067497 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Complete mitochondrial genome of a malaria vector mosquito Anopheles sinensis from South Korea | We present the complete mitochondrial genome of a Malaria vector Mosquito Anopheles sinensis Wiedemann, 1828 from South Korea. The mitochondrial genome is about 15,421 bp long and contains 13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes, and an A-T rich region. The present data were compared with those from China with respect to PCG sequence differences, tRNA structure, gene order, and control region (CR) structure. An. sinensis mitochondrial genomes from northeast Asia share identical gene composition and gene order. In contrast, they have distinct differences in the CR within the range 8.75% (51/583 bp) to 9.95% (58/583 bp). The phylogenetic analysis showed that An. sinensis from South Korea was clustered together with those from China, but there existed distinct genetic distance between the two. Likewise, mitochondrial genome sequences from other Anopheles species were employed to infer phylogenetic relationships among the members of the genus Anopheles. This study further promotes the enrichment of An. sinensis mitochondrial genome data, providing useful information for their mitochondrial genetic differences along with geographical distances in northeast Asia. | Akintola, Ashraf Akintayo; Park, Bia; Choi, Eun Hwa; Hwang, Ui Wook | Kyungpook Natl Univ, Sch Ind Technol Adv, Daegu, South Korea; Kyungpook Natl Univ, Dept Biol Educ, Teachers Coll, Daegu, South Korea; Kyungpook Natl Univ, Inst Phylogen & Evolut, Daegu, South Korea; Kyungpook Natl Univ, Inst Korean Herb Bio Convergence Promot, Daegu, South Korea | Akintola, Ashraf/KZU-7081-2024; Choi, Eun Hwa/HTN-1610-2023 | 57218618629; 57191834404; 57203556599; 35074015800 | uwhwang1@gmail.com; | MITOCHONDRIAL DNA PART B-RESOURCES | MITOCHONDRIAL DNA B | 2380-2359 | 7 | 5 | SCIE | GENETICS & HEREDITY | 2022 | 0.5 | 98.5 | 0.17 | 2025-06-25 | 3 | 2 | Anopheles sinensis; mitochondrial genome; phylogeny; South Korea | MOLECULAR EVIDENCE; HYRCANUS GROUP; DIPTERA; CHINA | Anopheles sinensis; mitochondrial genome; phylogeny; South Korea | English | 2022 | 2022-05-04 | 10.1080/23802359.2022.2077665 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The complete chloroplast genome of Ziziphus jujuba cv. Bokjo (Rhamnaceae) | We have sequenced the Ziziphus jujuba cv. Bokjo chloroplast genome by de novo assembly using next-generation sequencing. The complete circular chloroplast genome consisted of 161,714 bp and contained four parts: a large single-copy (LSC) region of 89,323 bp, a small single-copy (SSC) region of 19,361 bp, and two inverted repeat regions (IRa and IRb) of 26,515 bp each. The genome annotation predicted a total of 110 genes, including 76 protein-coding genes, 30 tRNA genes, and four rRNA genes. Phylogenetic analysis demonstrated the close taxonomic relationship between Z. jujuba cv. Bokjo and two other members of the Ziziphus genus, Z. spina-christi and Z. mauritiana. We found 135 polymorphic loci, 63 single nucleotide polymorphism (SNP) and 72 insertion-deletion (InDel), from the comparison of Z. jujuba cultivar Bokjo and Z. jujuba reference (NC₀₃₀₂₉₉). The polymorphic loci could be used for the differentiation of Z. jujuba genetic resources and for breeding in the future. | Kim, Moonkyo; Park, Jin Hee; Gil, Jinsu; Kim, Jung Sung; Kim, Hyoung Tae; Oh, Ha Kyung; Lee, Kyeong Hee; Lee, Minjee; Lee, Jungho; Lee, Yi | Chungbuk Natl Univ, Dept Ind Plant Sci & Technol, Cheongju 28644, South Korea; Korea Polar Res Inst, Incheon, South Korea; Nakdonggang Natl Inst Biol Resources, Sangju, South Korea; Chungbuk Natl Univ, Dept Forest Sci, Cheongju, South Korea; Kyungpook Natl Univ, Coll Ecol & Environm Sci, Sangju, South Korea; Chungcheongbuk Agr Res & Extens Serv, Cheongju, South Korea; Green Plant Inst, Yongin 16954, South Korea | 57279625000; 57204550333; 57188742674; 55227125400; 56181017100; 57218916391; 55884912000; 57201872199; 56828465300; 26039263300 | jlee@greenplant.re.kr;leeyi22@hanmail.net; | MITOCHONDRIAL DNA PART B-RESOURCES | MITOCHONDRIAL DNA B | 2380-2359 | 7 | 10 | SCIE | GENETICS & HEREDITY | 2022 | 0.5 | 98.5 | 0.17 | 2025-06-25 | 2 | 2 | Chloroplast genome; next-generation sequencing; Ziziphus jujuba | Chloroplast genome; next-generation sequencing; Ziziphus jujuba | English | 2022 | 2022-10-03 | 10.1080/23802359.2022.2131366 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Sit-up dizziness and head-shaking dizziness may be diagnostic symptoms of vestibular migraine | Background: Vestibular migraine (VM) frequently presents as a diagnostic challenge because objective neurological findings consistent with this entity have not been described. Certain patients with VM present with dizziness while sitting up or shaking their head, which we have designated as sit-up dizziness (SUD) and head-shaking dizziness (HSD) respectively. Objective: To study the prevalence of SUD and HSD in patients with acute VM and to evaluate their sensitivity and specificity for the diagnosis of acute VM. Methods: We examined 60 patients with VM and compared them to 61 patients with episodic migraine (EM), who were subsequently divided into 4 groups (acute-VM, symptom-free-VM, acute-EM, symptom-free-EM). SUD was induced by a positional change from lying to sitting, while HSD was induced by voluntary horizontal head-shaking. The prevalence of SUD and HSD was assessed in the patients during acute and asymptomatic periods. The sensitivity and specificity of SUD and HSD for identification of VM were assessed in an additional 85 patients with acute VM and 123 patients with acute EM. Results: The prevalence of SUD and HSD was 72% and 60% respectively in the acute-VM group, which was significantly higher than the symptom-free-VM, acute-EM and symptom-free-EM groups, and which was not related to sex, age, or symptom duration. SUD and HSD had a sensitivity of 80.0% and 81.2%, and specificity of 75.6% and 78.9%, respectively in diagnosing acute VM. The sensitivity and specificity for either test being positive was 91.8% and 71.5%, and 69.4% and 82.9%, when both tests were positive, respectively. Conclusions: SUD and HSD can be used as diagnostic indicators of acute VM that possess high sensitivity and specificity. This study suggests that SUD and HSD are useful diagnostic tests in patients with new dizziness of unknown cause. | Han, Byung In; Lee, HoWon; Ryu, Sanghyo; Park, Miso S.; Kim, Byungkun | Do Neurol Clin, 359 Jungang Daero, Daegu, South Korea; Kyungpook Natl Univ, Dept Neurol, Daegu, South Korea; Dr Ryus Neurol Clin, Dept Neurol, Busan, South Korea; Daejeon Univ, Clin Trial Ctr, Daejeon Korean Med Hosp, Daejeon, South Korea; Eulji Univ, Eulji Med Ctr, Dept Neurol, Seoul, South Korea | Ryu, Sanghyo/KCK-0912-2024 | 15062896700; 35337240700; 57221809954; 57478827300; 55855930800 | byung_in@hotmail.com;sanghyoryu@gmail.com; | NEUROLOGY ASIA | NEUROL ASIA | 1823-6138 | 27 | 1 | SCIE | CLINICAL NEUROLOGY | 2022 | 0.2 | 99.8 | 0 | 2025-06-25 | 0 | 0 | Dizziness; sit-up dizziness; head-shaking dizziness; vestibular migraine; episodic migraine | VERTIGO | Dizziness; episodic migraine; head-shaking dizziness; sit-up dizziness; vestibular migraine | amitriptyline; dimenhydrinate; flunarizine; mosapride; topiramate; adult; aged; Article; asymptomatic disease; benign paroxysmal positional vertigo; body position; canalolithiasis; comparative study; controlled study; demographics; diagnostic accuracy; diagnostic reasoning; diagnostic test accuracy study; disease assessment; disease duration; dix hallpike maneuver; dizziness; episodic migraine; evaluation and follow up; evening dosage; female; follow up; gender; head rolling; head shaking; head shaking dizziness; headache; human; international headache society criteria; major clinical study; male; middle aged; migraine; neck flexing; prevalence; prophylaxis; recumbency; sensitivity and specificity; sit up dizziness; statistical analysis; supine position; symptom; symptomatology; vestibular migraine; voluntary movement | English | 2022 | 2022-03 | 10.54029/2022hwz | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Proceedings Paper | 3-levels-stacked InxGa1-xAs Multi-Bridge Channel Field-Effect-Transistors | The gate-all-around (GAA) multi-bridge channel FET (MBCFET) architecture is believed to be the final evolutionary step for Moore's law. To achieve a sufficient amount of I-ON at low V-DD, it would be essential to use high-mobility channel materials including III-Vs and Ge. In particular, indium- rich InxGa1-xAs material systems with x in excess of 0.53 are regarded as a promising channel material for future CMOS logic and memory applications due to their exceptional electron carrier transport properties, including a very high injection velocity (vinj). In this talk, we present 3-levels-stacked In0.53Ga0.47As GAA MBCFETs with selectively regrown n+ In0.53Ga0.47As source/drain contacts by MOCVD. For a device fabrication, we use an epitaxy wafer with an In0.53Ga0.47As/In0.52Al0.48As multi-superlattice structure, and vertically stacked channels are electrically connected to selectively regrown n+ In0.53Ga0.47As contacts in the source/drain region. In0.52Al0.48As sacrificial layers are etched isotropically with an HCl-based etchant, releasing the In0.53Ga0.47As nanosheet (NS) channel layers. The device adopts an ALD-grown high-k dielectric layer of HfO2 and a TiN metal gate to implement the GAA structure. The fabricated MBCFETs with L-g = 130 nm, W-NS = 300 nm and t(NS) = 15 nm exhibit a combination of I-ON = 2.2 mA/square m and g(mₘₐₓ) = 5.7 mS/square m at V-DS = 0.8 V, making efficient use of each multi-bridge channel along the S/D and gate width directions. | Lee, In-Geun; Jo, Hyeon-Bhin; Yoo, Ji-Hoon; Lee, Jae-Hak; Kim, Dae-Hyun | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | Jo, Hyeon Bhin/HLW-9536-2023; Kim, Dae-Hyun/AAA-4463-2020 | 2022 INTERNATIONAL CONFERENCE ON IC DESIGN AND TECHNOLOGY (ICICDT) | 2381-3555 | 2691-0462 | 0 | English | 2022 | 2022 | 10.1109/icicdt56182.2022.9933121 | 바로가기 | 바로가기 | |||||||||||||||||||||
| ○ | ○ | Proceedings Paper | 3D Deployment of UAVs for Communications under Multiple Eavesdroppers | This paper proposes to use UAVs with adjustable beamforming as mobile base stations and studies to deploy them in a 3D manner to ensure secure communications in the presence of eavesdroppers. We aim to deploy the UAVs with appropriate beamforming in the optimal positions to maximize the signal strength of normal users while jamming the eavesdroppers by minimizing their received signal strength. Specifically, the objective is to maximize the total number of successfully served APs and jammed eavesdroppers. To achieve the goals, we propose a genetic algorithm (GA) by adjusting the 3D positions and beamwidths of UAVs. Simulation results show that the signal-to-interference-noise-ratio (SINR) threshold significantly affects the overall performance, and the proposed GA outperforms the existing differential evolution algorithm (DE). | Zhao, Ke; Razaq, Mian Muaz; Li, Kaixin; Peng, Limei; Ho, Pin-Han | Kyungpook Natl Univ, Sch Comp Sci & Engn, Deagu, South Korea; Univ Waterloo, Dept Elect & Comp Engn, Waterloo, ON, Canada | Razaq, Muaz/ACN-8991-2022; li, kaixin/JLM-8212-2023 | 57439189700; 57221661906; 58068987800; 7201574271; 7402211578 | kezhao@knu.ac.kr;mianmuaz97@knu.ac.kr;kaixinli@knu.ac.kr;auroraplm@knu.ac.kr;p4ho@uwaterloo.ca; | 2022 INTERNATIONAL CONFERENCE ON NETWORKING AND NETWORK APPLICATIONS, NANA | 0.24 | 2025-06-25 | 1 | 1 | SINR; UAV deployment; Eavesdropper; Directional Antenna; UAV secure communications | ALTITUDE | Directional Antenna; Eavesdropper; SINR; UAV deployment; UAV secure communications | Beam forming networks; Beamforming; Directive antennas; Genetic algorithms; Jamming; Secure communication; Signal to noise ratio; Base studies; Directional Antenna; Eavesdroppe; Mobile base station; Optimal position; Received signal strength; Signal strengths; Signalto-interference noise ratios (SINR); UAV deployment; UAV secure communication; Unmanned aerial vehicles (UAV) | English | 2022 | 2022 | 10.1109/nana56854.2022.00081 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Proceedings Paper | 3D Map Reconstruction From Single Satellite Image Using a Deep Monocular Depth Network | In this paper, we propose a 3D reconstruction scheme from single image with deep monocular depth estimation network, BTS (From Big to Small: Multi-Scale Local Planar Guidance for Monocular Depth Estimation) [1]. Furthermore, we expand it to height estimation focused building from remote sensing images. To address these issues, we substitute depth estimation loss function with height estimation loss function. Moreover, considering improving the quality of the building height map and looking as similar as possible to the ground-truth view, we apply building adaptive loss function. | Son, Changmin; Park, Soon-Yong | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Park, Soon-Yong/HGV-2374-2022 | 57826492700; 7501834063 | tptkddmldkdl@gmail.com;sypark@knu.ac.kr; | 2022 THIRTEENTH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS (ICUFN) | 2165-8528 | 2165-8536 | 1.27 | 2025-06-25 | 4 | 5 | 3D map; Monocular height estimation; Deep learning; Remote sensing image | 3D map; Deep learning; Monocular height estimation; Remote sensing image | Deep learning; Remote sensing; 3D maps; 3D reconstruction; Deep learning; Depth Estimation; Height estimation; Loss functions; Map reconstruction; Monocular height estimation; Remote sensing images; Satellite images; Image reconstruction | English | 2022 | 2022 | 10.1109/icufn55119.2022.9829688 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Proceedings Paper | 3D SURFACE RECONSTRUCTION FROM MULTI-VIEW AND MULTI-DATE GOOGLE EARTH SATELLITE IMAGES WITH 3D HOMOGRAPHY-BASED PROJECTIVE RECONSTRUCTION | In this paper, we propose the 3D surface reconstruction scheme using multi-view and multi-date Google Earth (GE) satellite images. Multi-view stereo matching (MVS) scheme is one of the methods for reconstructing dense 3D surface based on multi-view images and corresponding camera pose geometry. If many views are input, MVS can estimate the disparity (depth) by matching pixels. However, the common users are not always possible to obtain both multi-view satellite images and the camera geometry (such as Rational Polynomial Camera) in various earth regions. Instead, the GE provides multi-view and multi-date satellite images of earth regions. Therefore, the goal of the proposed method is to perform a 3D surface reconstruction using the GE satellite image. We suppose that the GE satellite image is a pinhole camera model, and the camera pose geometry is estimated using the perspective projection model (PPM) based structure from the motion (SfM) method. Then the 3D surface is reconstructed and fusion using the MVS method. However, the GE satellite image is a transformed pseudo-orthoimage for integration into the raster image. For this reason, the camera pose geometry is inaccurately computed in the SfM process. Thus, the high-rise structures in the reconstructed 3D surface are distorted (distorted hexahedral 3D space). Importantly, the satellite image is a weak PPM and it can express the orthographic projection model. Therefore, we compute 3D homography for transforming between distorted hexahedral space to orthographic cuboid space. Then, the distorted 3D surface is transformed using a projective reconstruction based on 3D homography. The transformed 3D surface has the correct shape in the orthographic projection model. The advantage of the proposed method is that the 3D surface of various earth regions is reconstructed using simply accessible GE satellite images. And the transformed 3D surface is reconstructed into orthographic projection model space, thus the orthoimage can be generated using projection. | Lee, M. J.; Park, S.

| ○ | Article | A Case of Laryngeal Amyloidosis: Role of US and US-CNB for Preoperative Diagnosis; [후두 아밀로이도증 1예: 초음파 및 초음파 유도하 중심 바늘 생검의 진단적 역할] | Amyloidosis is a rare benign disease characterized by the extracellular deposition of nonsoluble fibrillar proteins (amyloids) within organs. Laryngeal amyloidosis (LA) accounts for only 9%-15% of all cases of amyloidosis. Since clinical manifestations and laryngoscopic findings often overlap with those of laryngeal cancer, it is challenging to differentiate LA from laryngeal cancer prior to surgical biopsy. We report a case of LA mimicking laryngeal cancer, in which the diagnosis was facilitated by preoperative ultrasonography (US) and US-guided core-needle biopsy (US-CNB) prior to surgical biopsy. The US findings of this case were distinguishable from those of laryngeal cancer, which enabled us to consider a diagnosis other than laryngeal cancer. Amyloidosis was diagnosed preoperatively using office-based percutaneous US-CNB, avoiding general anesthesia needed for suspension laryngoscopic examination. This case suggests that US and US-CNB could be used as supplementary diagnostic modalities to evaluate suspicious laryngeal masses mimicking laryngeal cancer.

| ○ | ○ | Article | A case of pulmonary thromboembolism possibly associated with the use of creatine supplements | Drug administration should be considered a risk factor for venous thromboembolism (VTE) in younger healthy patients. We present a case of new-onset pulmonary embolism (PE), possibly associated with excessive creatine supplement intake. A 24-year-old non-smoker male presented to the emergency department with sudden-onset dyspnoea and chest discomfort. Computed tomography pulmonary angiography and venography confirmed PE in the left and right pulmonary artery branches and a thrombus in the left popliteal vein. The patient had no family history of VTE, and other causes of thrombophilia were unlikely. He reported a recent increase in the intensity of his workouts and the dose of his creatine supplements in preparation for a bodybuilding competition. The creatine supplements likely promoted dehydration during intense workouts and profuse sweating. He received anticoagulation therapy, and the creatine supplements were discontinued. Creatine supplements should be used cautiously when there is a higher risk of becoming dehydrated. | Lee, So Hyun; Seo, Jin A.; Park, Ji Eun; Kim, Chang Ho; Lee, Jaehee | Kyungpook Natl Univ, Sch Med, Dept Internal Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Lee, Seung/A-3743-2012; Lee, Jaehee/S-1697-2018; Lee, Yoojin/AAB-9799-2022 | 57219300632; 57555138700; 57195437358; 7409873555; 13805476000 | jaelee@knu.ac.kr; | RESPIROLOGY CASE REPORTS | RESPIROL CASE REP | 2051-3380 | 10 | 4 | ESCI | RESPIRATORY SYSTEM | 2022 | 0.8 | 0.11 | 2025-06-25 | 2 | 1 | creatine supplement; dehydration; thromboembolism | creatine supplement; dehydration; thromboembolism | gamma interferon; immunoglobulin A; immunoglobulin G; immunoglobulin G antibody; immunoglobulin M; neutralizing antibody; tozinameran; vaxzevria; adult; antibody response; Article; body mass; cellular immunity; coronavirus disease 2019; enzyme linked immunosorbent assay; female; health care personnel; human; human experiment; humoral immunity; immunity; longitudinal study; male; neutralization test; normal human; observational study; Severe acute respiratory syndrome coronavirus 2; vaccination | English | 2022 | 2022-04 | 10.1002/rcr2.932 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
