| ○ | ○ | Article | Confirmation of COVID-19 in Out-of-Hospital. Cardiac Arrest Patients and Postmortem Management in the Emergency Department during the COVID-19 Outbreak | Csackground: There is currently a lack of evidence-based postresuscitation or postmortem guidelines for patients with out-of-hospital cardiac arrest (OHCA) in the setting of an emerging infectious disease. This study aimed to develop and validate a multimodal screening tool that aids in predicting the disease confirmation in emergency situations and patients with OHCA during a coronavirus disease 2019 (COVID-19) outbreak. Materials and Methods: We conducted a retrospective, multicenter observational study of adult patients with OHCA in Daegu, Korea. To identify the potential predictors that could be used in screening tools in the emergency department, we applied logistic regression to data collected from March 1 to March 14. The prediction performance of the screening variables was then assessed and validated on the data of patients with OHCA who were treated between February 19 and March 31, 2020. General patient characteristics and hematological findings of the COVID-19-negative and COVID-19-positive groups were compared. We also evaluated confirmation test criteria as predictors for COVID-19 positivity in patients with OHCA. Results: Advanced age, body temperature, and abnormal chest X-ray (CXR) revealed significant predictive ability in the derivation cohort. Of the 184 adult patients with OHCA identified in the validation cohort, 80 patients were included in the analysis. Notably, 9 patients were positive and 71 were negative on the COVID-19 reverse transcription polymerase chain reaction test. Five patients (55.6%) in the COVID-19-positive group had a fever before OHCA, and 12 (16.9%) of the COVID-19-negative group had a fever before OHCA (P= 0.018). Eight patients (88.9%) in the COVID-19-positive group had a CXR indicating pneumonic infiltration. Of the criteria for predicting COVID-19, fever or an abnormal CXR had a sensitivity of 100% (95% confidence interval [CI]: 65.4 -100) and a specificity of 22.5% (95% CI: 13.5 - 34.0). Conclusion: The screening tools that combined fever or abnormal CXR had a good discriminatory ability for COVID-19 infection in adult patients with OHCA. Therefore, during the COVID-19 outbreak period, it is recommended to suspect COVID-19 infection and perform COVID-19 test if patients present with a history of fever or show abnormal findings in postmortem CXR. | Kim, Changho; Yeo, In Hwan; Kim, Jong Kun; Cho, Yeonjoo; Lee, Mi Jin; Jung, Haewon; Cho, Jae Wan; Ham, Ji Yeon; Lee, Suk Hee; Chung, Han Sol; Mun, You Ho; Lee, Sang Hun; Kim, Yang Hun | Kyungpook Natl Univ, Sch Med, Dept Emergency Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Clin Pathol, Daegu, South Korea; Daegu Catholic Univ, Dept Emergency Med, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Emergency Med, Daegu, South Korea; Keimyung Univ, Dept Emergency Med, Dongsan Hosp, Daegu, South Korea; Daegu Fatima Hosp, Dept Emergency Med, Daegu, South Korea | ; Kim, Joo/JAZ-0897-2023; Yeo, Inhwan/GXZ-7024-2022 | 56441824200; 57216816807; 55915816900; 57219251787; 55507282600; 57221554827; 7403536065; 56464754800; 57205602138; 57216815984; 57210884077; 57210919228; 57216816375 | inani1113@gmail.com; | INFECTION AND CHEMOTHERAPY | INFECT CHEMOTHER | 2093-2340 | 2092-6448 | 52 | 4 | ESCI | INFECTIOUS DISEASES | 2020 | N/A | 0.51 | 2025-06-25 | 7 | 7 | COVID-19; Heart arrest; Fever; Chest X-ray; Screening | Chest X-ray; COVID-19; Fever; Heart arrest; Screening | adult; advanced cardiac life support; age; aged; Article; body temperature; breathing rate; clinical feature; clinical outcome; cohort analysis; coronavirus disease 2019; coughing; diastolic blood pressure; dyspnea; emergency health service; emergency ward; epidemic; false negative result; female; fever; high risk population; hospitalization; human; Korea; major clinical study; male; observational study; out of hospital cardiac arrest; oxygen saturation; pleura effusion; pneumonia; posthumous care; practice guideline; predictive value; pulse rate; retrospective study; return of spontaneous circulation; reverse transcription polymerase chain reaction; sensitivity and specificity; Severe acute respiratory syndrome coronavirus 2; sore throat; systolic blood pressure; tachypnea; thorax radiography | English | 2020 | 2020-12 | 10.3947/ic.2020.52.4.562 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Confronting minimal freeze-in models with the LHC | We present a class of dark matter models, in which the dark matter particle is a feebly interacting massive particle (FIMP) produced via the decay of an electrically charged and/or colored parent particle. Given the feeble interaction, dark matter is produced via the freeze-in mechanism and the parent particle is long-lived. The latter leads to interesting collider signatures. We study current LHC constrains on our models arsing from searches for heavy charged particles, disappearing tracks, displaced leptons and displaced vertices. We demonstrate not only that collider searches can be a powerful probe of the freeze-in dark matter models under consideration, but that an observation can lead as well to interesting insights on the reheating temperature and thus on the validity of certain baryogenesis models. © 2019 CERN for the benefit of the ATLAS and CMS Collaborations.

| ○ | ○ | Proceedings Paper | Congestion Window Scaling Method for Inter-protocol Fairness of BBR | Unlike the existing loss-based and delay-based congestion control algorithms, the Bottleneck Bandwidth Round-trip propagation time (BBR) congestion control algorithm determines the amount of sending data to be transferred at a specific time by calculting BDP (Bandwidth Delay Product). However, when BBR competes with loss-based congestion control algorithms, such as Reno and CUBIC, most of the bottleneck bandwidth is occupied by specific flows or excessive packet loss occurs. In previous work, we proposed an improved loss recovery mechanism in order to address above problems. Through the previous proposal, the fairness between BBR and loss-based algorithms was improved if the buffer size was larger than 2 BDP. However, if the buffer size was smaller than 2 BDP, the performance imbalance and continuous packet retransmission still occurred. In this paper, we propose a congestion window upper scaling method that complements the previously proposed loss recovery mechanism. In addition, we conduct an experiment and evalute its enhanced performance in a Mininet emulator. | Song, Yeong-Jun; Kim, Geon-Hwan; Cho, You-Ze | Kyungpook Natl Univ, Sch Elect Enginerring, Daegu, South Korea | 57210919165; 57189040274; 7404469829 | sy15385@knu.ac.kr;kgh76@ee.knu.ac.kr;yzcho@ee.knu.ac.kr; | 2020 IEEE 17TH ANNUAL CONSUMER COMMUNICATIONS & NETWORKING CONFERENCE (CCNC 2020) | 2331-9852 | 1.32 | 2025-06-25 | 7 | 9 | TCP congestion control; BBR; CUBIC; inter-protocol fairness; retransmission | BBR; CUBIC; inter-protocol fairness; retransmission; TCP congestion control | Bandwidth; Packet networks; Bandwidth delay product; Bottleneck bandwidth; Congestion window; Delay-based congestion control; Packet retransmissions; Propagation time; Protocol fairness; Scaling method; Traffic congestion | English | 2020 | 2020 | 10.1109/ccnc46108.2020.9045307 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | ○ | Article | Conservative treatment of acute traumatic left renal vein occlusion: Importance of left gonadal vein, case report | INTRODUCTION: Isolated acute traumatic renal vein occlusion is rare. As both kidneys have limited capsular and peripelvic vein collaterals, acute renal vein occlusion could lead to renal infarction. However, the left renal vein has potential collateral pathways through the gonadal vein. PRESENTATION OF CASE: A 56-year-old woman was transferred to our trauma center after a pedestrian accident. Computed Tomography (CT) with contrast enhancement showed that no delineation of left renal vein with adjacent retroperitoneal hematoma around renal vessels, but left renal venous flow was being drained through left gonadal vein, therefore, left kidney was not congested. Her serum creatinine concentration was normal. We elected to treat her left renal vein occlusion conservatively because of the collateral pathway into the gonadal vein. DISCUSSION: Collateral pathway of the left renal venous drainage may be well known to urologists or vascular surgeons, but may be unfamiliar to trauma surgeons. Therefore, trauma surgeon's attempts for revascularization of thrombosed left renal vein may lead to massive bleeding or nephrectomy. CONCLUSION: Acute left renal vein occlusion close to the inferior vena cava can result in temporary venous hypertension and congestion followed by complete or nearly complete return of function as collateral veins enlarge. If the gonadal vein is patent, left renal vein occlusion could be treated conservatively. (C) 2020 The Author(s).

| ○ | Review | Considerations for virtual surgical planning and simulation in orthognathic surgery—a narrative review | Although there are many benefits to use 3D virtual surgical planning (VSP) for orthognathic surgery, there are only a few reports on the potential errors or mistakes that can occur with VSP and simulation processes. This narrative review updates information on VSP and discusses the various precautions and considerations for VSP in orthognathic surgery. Application of VSP allows visualization of the interosseous relationship, segment overlap or bony interference, and significant interosseous gaps. Potential sites for additional bone grafts or bone reduction can be anticipated. Additionally, presurgical planning can be performed with unlimited time. Since most VSP is performed by an outsourced company, quality assurance in VSP depends on a third-party, and sometimes there is lack of clarity when delineating the responsibilities for surgical outcomes. To increase the precision of 3D planning and simulation, surgeons need to be aware that the VSP cannot automatically ensure the success of surgical outcomes. Errors can occur at every step, such as integration of 3D dentition to skull data, segment identification and mobilization, computer-aided surgical simulation, fabrication of splint and surgical guides, 3D image superimposition, and determination of occlusion in virtual space. Thorough understanding of the source of errors in VSP can lead to successful surgical outcomes in orthognathic surgery performed with VSP. © Frontiers of Oral and Maxillofacial Medicine.

| ○ | ○ | Article | Content-Based Image Retrieval Using Multi-Resolution Multi-Direction Filtering-Based CLBP Texture Features and Color Autocorrelogram Features | We propose a content-based image retrieval system that uses a combination of completed local binary pattern (CLBP) and color autocorrelogram. CLBP features are extracted on a multi-resolution multi-direction filtered domain of value component. Color autocorrelogram features are extracted in two dimensions of hue and saturation components. Experiment results revealed that the proposed method yields a lot of improvement when compared with the methods that use partial features employed in the proposed method. It is also superior to the conventional CLBP, the color autocorrelogram using R, G, and B components, and the multichannel decoded local binary pattern which is one of the latest methods. | Bu, Hee-Hyung; Kim, Nam-Chul; Yun, Byoung-Ju; Kim, Sung-Ho | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57194698542; 36068144500; 7006416932; 57194701745 | hhbu@knu.ac.kr;nckim@knu.ac.kr;bjisyun@ee.knu.ac.kr;shkim@knu.ac.kr; | JOURNAL OF INFORMATION PROCESSING SYSTEMS | J INF PROCESS SYST | 1976-913X | 2092-805X | 16 | 4 | ESCI | COMPUTER SCIENCE, INFORMATION SYSTEMS | 2020 | N/A | 0.37 | 2025-06-25 | 6 | 8 | Autocorrelogram; Content-Based Image Retrieval; MRMD CLBP; Multi-Resolution Multi-Direction Filter | ROTATION-INVARIANT; FEATURE-EXTRACTION; SCALE | Autocorrelogram; Content-based image retrieval; MRMD CLBP; Multi-resolution multi-direction filter | Color; Content based retrieval; Textures; Color autocorrelogram; Content based image retrieval; Content based image retrieval systems; Local binary patterns; Multichannel; Texture features; Two-dimension; Search engines | English | 2020 | 2020-08 | 10.3745/jips.02.0138 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

Many control and navigation algorithms are experimented and deployed for UAVs, especially quadrotors. Recent numerous approaches are geared towards reducing the influence of external disturbances to enhance the performance of UAVs. Nevertheless, designing cutting-edge controllers following the requirements of the applications is still a huge challenge. Based on the operating characteristics and movement principle of a quadrotor, this work reviews potential control algorithms of the current researches in the field of the quadrotor flight controller. Besides, a comparison has been made to provide an overview of the advantages and disadvantages of the mentioned methods. At last, the challenges and future directions of the quadrotor flight controller are suggested. © 2020. Hoa T. Nguyen et al., licensed to EAI.

| ○ | ○ | Article | Control Methods for Operation on the Saturation Edge | For some processes with saturations, economical operating points are on the saturation edges. Traditional feedback controllers cannot be used to regulate such processes on the saturation edges because there are abrupt dynamics changes and no feedback information at saturations. Optimization-based methods such as the model predictive control can treat this control problem without difficulty when the saturation levels and dynamics are known and not varying. Otherwise, an adaptation scheme to track the saturation levels and dynamics should be included. Here, for very simple methods to treat this control problem, two control methods based on the recent slope seeking method and the relay feedback method are proposed. Their performances are evaluated with simulations applying them to a second order liquid level system with saturation. Simulations show that these proposed control methods can find and maintain operating point of the saturation edge under 5% relative error. | Ahn, Gwang Noh; Lim, Sanghun; Sung, Su Whan; Lee, Jietae | Kyungpook Natl Univ, Dept Chem Engn, 80 Daehak Ro, Daegu 41566, South Korea | Lee, Si/ABH-1408-2020 | 57210798725; 57218849821; 7202731867; 7601455194 | jtlee@knu.ac.kr; | KOREAN CHEMICAL ENGINEERING RESEARCH | KOREAN CHEM ENG RES | 0304-128X | 2233-9558 | 58 | 3 | ESCI | ENGINEERING, CHEMICAL | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | Control on the Saturation Edge; Extremum Seeking Control; Relay Feedback Control; Vaporization; Chemical Reaction | FEEDBACK; SEEKING | Chemical Reaction; Control on the Saturation Edge; Extremum Seeking Control; Relay Feedback Control; Vaporization | Korean | 2020 | 2020-06 | 10.9713/kcer.2020.58.3.390 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Controllable synthesis of silica nanoparticle size and packing efficiency onto PVP-functionalized PMMA via a sol-gel method | This study aimed to investigate synthesis and adsorption behavior of silica nanoparticles onto polyvinylpyrrolidone (PVP)-functionalized poly(methyl methacrylate) under various conditions such as methanol/water ratio, ammonium hydroxide concentration, polymer contents, tetraethylorthosilicate contents, and total volume of solvent via sol-gel method. First, the copolymerization of methyl acrylate as a comonomer and 1-dodecanethiol as a chain transfer agent increased the thermal stability of the product; however, the uniformity of the PMMA particles decreased because of the chain transfer reaction. Second, the adsorption behavior and size of silica nanoparticles could be controlled by adjusting the silica synthesis conditions. The adsorbed silica particle size was greatly influenced by the ammonium hydroxide concentration and the addition of water further enhanced the size increase. However, increasing the water content reduced the packing efficiency of the adsorbed silica particles. Increasing the PVP-functionalized PMMA content at a fixed TEOS content linearly decreased the silica particle size. But TEOS concentration did not significantly affect the silica particle size.

| ○ | ○ | Article | Correction of microtia with constriction features using a superficial temporal fascial flap combined with a rib cartilage graft | Background Microtia with constricted features is characterized by a short helical length of variable severity, upper antihelical or scaphal deficiency, and a downfolded upper ear. No consensus has been reached regarding the most appropriate surgical method for this condition. In this study, we aimed to introduce a simple and safe surgical method for the correction or reconstruction of upper helix ear deformities. Methods Between February 2011 and June 2014, eight patients with microtia with constricted upper helix ear deformity underwent reconstruction of the ear deformity. The upper ear helical framework was constructed by carving and curving the eighth rib cartilage harvested from the ipsilateral chest wall, covering this cartilage with a superficial temporal fascial flap, and adjusting the skin graft to align with the ear contour. To evaluate their satisfaction, patients were asked to complete a questionnaire regarding ear shape, symmetry, position, color, and overall outcome scored on a 5-point scale at 12 months postoperatively. Results None of the patients experienced severe complications in the reconstructed ear. The preoperative and postoperative vertical ear length ratios were 0.88 and 1.02, respectively. And the mean patient satisfaction scores for shape, symmetry, position, color, and overall outcome were 4.2, 4.5, 4.7, 4.4, and 4.6 out of 5 points, respectively. All patients expressed a high level of satisfaction at 12 months postoperatively. Conclusions Our technique provides a good alternative method for the reconstruction of moderate constricted upper helix ear deformities in patients who meet the surgical indications with satisfactory outcomes and few complications. | Lee, Joon Seok; Kim, Jong Seong; Lee, Jeong Woo; Choi, Kang Young; Yang, Jung Dug; Chung, Ho Yun; Cho, Byung Chae | Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 807 Hoguk Ro, Daegu 41404, South Korea | Lee, Woo Hyuk/HTT-3694-2023; LEE, JIN/Q-3108-2018; Yang, Jung/R-7806-2019 | 56496041000; 57210152149; 55892173700; 57203745682; 55171704700; 7404007181; 55662871100 | medps@knu.ac.kr; | ARCHIVES OF PLASTIC SURGERY-APS | ARCH PLAST SURG-APS | 2234-6163 | 2234-6171 | 47 | 4 | ESCI | SURGERY | 2020 | N/A | 0.45 | 2025-06-25 | 5 | 6 | Ears prominent and constricted; Congenital microtia; Ear auricle | EAR; LOP; CUP; MANAGEMENT | Congenital microtia; Ear auricle; Ears prominent and constricted | adult; Article; bleeding; bone remodeling; cartilage graft; cauterization; child; clinical article; Doppler ultrasonography; ear malformation; female; follow up; fracture; hematoma; human; incision; male; microtia; necrosis; patient satisfaction; pedicled skin flap; perichondrium; photometry; questionnaire; rectus abdominis muscle; rib cartilage; scar formation; school child; seroma; skin graft; split thickness skin graft; surgical flaps; temporal artery; thorax wall; young adult | English | 2020 | 2020-07 | 10.5999/aps.2018.01165 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | Article | Correlations of induced sputum eosinophils with blood allergic markers in pediatric asthma and eosinophilic bronchitis | Purpose: Induced sputum eosinophil count is useful for the evaluation and diagnosis of asthma and eosinophilic bronchitis (EB). The aim of this study was to evaluate the correlation of induced sputum eosinophil count with various allergic indicators, including the peripheral blood eosinophil count, in pediatric asthma and EB. Methods: From May 2014 to July 2018, 126 children visited Kyungpook National University Children's Hospital, and underwent methacholine bronchial challenge test and sputum induction. Peripheral blood eosinophil counts, serum eosinophil cationic protein (ECP), serum total IgE, immunoCAP for inhalant allergens, and skin prick test were performed in the study subjects. Results: In the asthma group, the eosinophil count of induced sputum correlated with peripheral blood eosinophils (r= 0.279, P= 0.043). The concordance rates of sputum and peripheral blood eosinophil count in the asthma and EB groups were 64.1% and 25.7%, respectively. The number of eosinophils in the sputum also correlated with serum total IgE, ECP, and specific IgE to Dermatophagoides farinae, Dermatophagoides pteronyssinus, and Aspergillus in the asthma group. Conclusion: The number of eosinophils in the induced sputum correlated with peripheral blood in the asthma group. However, a third of subjects were discordant. Therefore, we need to keep in mind the possibility of discordance when predicting the degree of airway eosinophilic inflammation using the peripheral blood eosinophils. In EB, the number of induced sputum eosinophils did not correlate with the number of peripheral blood eosinophils, which may be attributed to the difference in mechanism. Further studies are warranted. | Park, Gyun; Kim, Hyeona; Kwon, Jung Eun; Kim, Dong Sub; Choe, Jae Young; Ahn, Ji Young; Choi, Bong Seok | Kyungpook Natl Univ, Sch Med, Dept Pediat, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Emergency Med, Daegu, South Korea; Yeungnam Univ, Dept Pediat, Coll Med, Daegu, South Korea | ahn, jiyoung/KSM-2201-2024; Kim, Dong/G-7392-2017 | bschoi@knu.ac.kr; | ALLERGY ASTHMA & RESPIRATORY DISEASE | ALLERGY ASTHMA RESPI | 2288-0402 | 2288-0410 | 8 | 4 | ESCI | ALLERGY | 2020 | N/A | 1 | Asthma; Bronchitis; Eosinophil; Sputum; Serum | AIRWAY SMOOTH-MUSCLE; CHRONIC COUGH; CELL COUNTS; INFLAMMATION; CHILDREN; GUIDELINES; EXPRESSION | Korean | 2020 | 2020-10 | 10.4168/aard.2020.8.4.220 | 바로가기 | 바로가기 | 바로가기 |
