| ○ | ○ | Article | Pulmonary arteriovenous malformation (PAVM) embolization: prediction of angiographically-confirmed recanalization according to PAVM Diameter changes on CT | Background: To assess pulmonary arteriovenous malformation (PAVM) recanalization after embolization based on PAVM diameter changes on computed tomography (CT), with pulmonary angiography used as a gold standard. Methods:A retrospective review was done of patients from 2008 to 2019 with a PAVM treated with endovascular embolization. The treatment outcome was determined by conventional angiography. Follow-up pulmonary angiography was performed when recanalization was suspected on CT, or embolization of all lesions in multiple PAVM patients could not be completed in a single session. Patients who had no preprocedural or follow-up CT were excluded. Draining vein, feeding artery, and venous sac diameter were measured on CT, and diameter reduction rates were compared with the widely-used, binary 70% criteria. Results:Forty-one patients with 114 PAVMs were treated during the study period. Eight patients with 50 PAVMs met the inclusion criteria. Mean vein, artery, and venous sac diameter reduction rates were as follows: 59.29.3%, 47.5 +/- 10.6%, and 62.6 +/- 13.2%, respectively, in the occluded group and 5.4 +/- 19.5%, 11.3 +/- 17.7%, and 26.8 +/- 14.2%, respectively, in the recanalized group. The area under the receiver operating characteristic curves for PAVM recanalization for the draining vein was 1.00, showing a better result than the artery (0.97) and sac (0.99). Patients showed>42% draining vein diameter reduction in the occluded group and <32% in the recanalized group. The widely-used 70% criteria showed low specificity for predicting recanalization (draining vein, 7.3%; venous sac, 41.7%) but 100% sensitivity for both the draining vein and venous sac. Conclusions:The widely-used 70% binary criteria showed limited performance in predicting outcomes in this angiographically-confirmed case series. Further investigations are warranted to establish a strategy for detecting recanalization after PAVM embolization. | Hong, Jihoon; Lee, Sang Yub; Cha, Jung Guen; Lim, Jae-Kwang; Park, Jongmin; Lee, Jaehee; Cha, Seung-Ick; Kim, Chang-Ho; Seo, Hyewon | Kyungpook Natl Univ Hosp, Dept Radiol, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea | Lee, Joo/C-3851-2013; Lee, Jaehee/S-1697-2018; Lee, Jun Young/CAI-2335-2022 | 57215858314; 56016177400; 57206855971; 55515341400; 57216463879; 13805476000; 35227126400; 7409873555; 55612130200 | lsyrad@gmail.com; | CVIR ENDOVASCULAR | CVIR ENDOVASC | 2520-8934 | 4 | 1 | ESCI | CARDIAC & CARDIOVASCULAR SYSTEMS;PERIPHERAL VASCULAR DISEASE;RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING | 2021 | N/A | 1.05 | 2025-07-30 | 12 | 14 | Pulmonary arteriovenous malformation; Transcatheter embolization; Computed tomography | RESOLVED MR-ANGIOGRAPHY; VASCULAR PLUG; EMBOLOTHERAPY; REPERFUSION; SAFETY; PERSISTENCE; PLATINUM; OUTCOMES | Computed tomography; Pulmonary arteriovenous malformation; Transcatheter embolization | heparin; lidocaine; adult; artery diameter; Article; artificial embolization; clinical outcome; computer assisted tomography; controlled study; conventional angiography; female; follow up; gold standard; human; local anesthesia; lung angiography; major clinical study; male; medical record review; middle aged; prediction; priority journal; pulmonary arteriovenous fistula; recanalization; receiver operating characteristic; retrospective study; sensitivity analysis; vein diameter | English | 2021 | 2021-01-18 | 10.1186/s42155-021-00207-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Pulmonary atresia with a ventricular septal defect and left pulmonary artery discontinuity: a case report | Background Unilateral pulmonary artery discontinuity is a rare malformation that is associated with other intracardiac abnormalities. Cases accompanied by other cardiac abnormalities are often missed on prenatal echocardiography. The prenatal diagnosis of isolated unilateral pulmonary artery discontinuity can also be delayed. However, undiagnosed this malformation would have an effect on further prognosis. We report our case of a prenatal diagnosis of pulmonary atresia with ventricular septal defect and left pulmonary artery discontinuity. Case presentation A 33-year-old Asian woman visited our institution at 24 weeks of gestation because of suspected fetal congenital heart disease. Fetal echocardiography revealed a small atretic main pulmonary artery giving rise to the right pulmonary artery without bifurcation and the left pulmonary artery arising from the ductus arteriosus originating from the left subclavian artery. The neonate was delivered by cesarean section at 37(6/7) weeks of gestation. Postnatal echocardiography and multidetector computed tomography showed a right aortic arch, with the small right pulmonary artery originating from the atretic main pulmonary artery and the left pulmonary artery originating from the left subclavian artery. Patency of the ductus arteriosus from the left subclavian artery was maintained with prostaglandin E1. Right ventricular outflow tract reconstruction and pulmonary angioplasty with Gore-Tex graft patch was performed 25th day after birth. Unfortunately, the neonate died because of right heart failure 8 days postoperation. Conclusion There is a possibility that both pulmonary arteries do not arise from the same great artery (main pulmonary artery or common arterial trunk). Therefore, clinicians should check the origin of both pulmonary arteries. | Cha, Hyun-Hwa; Kim, Hae Min; Seong, Won Joon | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Obstet & Gynecol, 807 Hogukro, Daegu 41404, South Korea | 37033517800; 57222634904; 26656946000 | wjseong81@gmail.com; | JOURNAL OF MEDICAL CASE REPORTS | 1752-1947 | 15 | 1 | 0.11 | 2025-07-30 | 1 | 1 | Fetal disease; Pulmonary artery; Echocardiography | REPAIR | Echocardiography; Fetal disease; Pulmonary artery | Adult; Cesarean Section; Female; Heart Defects, Congenital; Heart Septal Defects, Ventricular; Humans; Infant, Newborn; Pregnancy; Pulmonary Artery; Pulmonary Atresia; alprostadil alfadex; milrinone; Article; case report; clinical article; clinical feature; continuous positive airway pressure; echocardiography; female; gestational age; heart ventricle septum defect; hemoptysis; human; left pulmonary artery discontinuity; multidetector computed tomography; newborn; pericardial effusion; priority journal; pulmonary valve atresia; pulmonary vascular disease; tachycardia; adult; cesarean section; complication; congenital heart malformation; diagnostic imaging; heart septum defect; pregnancy; pulmonary artery; pulmonary valve atresia | English | 2021 | 2021-04-01 | 10.1186/s13256-021-02750-4 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Pure laparoscopic living donor hepatectomy for the right posterior segment graft | Introduction: The right posterior segment (RPS) graft was introduced as an alternative to expand donor pool. The first LDLT case using an RPS graft was reported in 2001, the RPS graft has not been widely used in LDLT because of lack of donors with suitable anatomical variation, technical challenge for safe donor hepatectomy and surgical difficulties in recipient operation. We present the 3 cases of pure laparoscopic donor hepatectomy with RPS graft. Methods: For donor evaluation, we performed laboratory test, abdominal ultrasonography and dynamic computed tomography (CT) scan. Graft selection was determined based on volumetric analysis. In 3 cases of RPS graft, the ratio of the remnant liver volume/ whole liver volume was less than 0.3 and left lobe graft was small for metabolic demand of recipients. All 3 donors had type 3 portal vein variation. The Graft Recipient Weight Ratio (GRWR) was 0.72, 0.81, and 1.34 in each case. Preoperative magnetic resonance cholangiopancreatography (MRCP) was performed to evaluate bile duct anomaly. Results: In 3 cases, we had no open conversion, intraoperative and postoperative transfusion. Cut surface bile leakage occurred in one case, but bile leakage decreased without procedure or intervention, the donor discharged at postoperative day 9. He had no more complications. Recipients were recovered uneventfully and discharged. Conclusions: To meet the donor’s safety and recipient’s metabolic demand, graft selection is one of the important factors in LDLT, the RPS graft is an alternative to expand donor pool. However, thorough preoperative evaluation to understand the anatomical variation is necessary even for experienced transplant surgeons. © The Korean Association of Hepato-Biliary-Pancreatic Surgery. | Han, Jaryung; Han, Young Seok | Division of Hepatobiliay Pancreas Surgery and Liver Transplantation, Department of Surgery, Kyungpook National University Hospital, Daegu, South Korea; Division of Hepatobiliay Pancreas Surgery and Liver Transplantation, Department of Surgery, Kyungpook National University Hospital, Daegu, South Korea | 57214671308; 7404096216 | gshys@knu.ac.kr; | Annals of Hepato-Biliary-Pancreatic Surgery | 2508-5778 | 25 | 0 | 2025-07-30 | 0 | English | Final | 2021 | 10.14701/ahbps.lv-op-1-5 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Quality characteristics and antioxidant activities of cheonggukjang prepared with soybean and lotus seeds | Cheonggukjang (CGJ) is a famous traditional Korean food that is typically produced by fermenting steamed soybean seeds and has a unique flavor and taste. The objective of this study was to evaluate the effect of addition of lotus seeds on the quality and antioxidant activities of CGJ. Color value, 1,1-diphenly-2-picrylhydrazyl radical scavenging potential, and the amounts of total polyphenol, total flavonoid, mineral, and free amino acid were evaluated. The CGJ sample produced with lotus alone or a mixture of soybean and lotus produced in Korea showed relatively high antioxidant potential. The amount of essential and total free amino acids was also high in the sample prepared with lotus seeds grown in Korea. On the other hand, the total mineral content was low in the lotus-based samples. The results indicated that a mixture of an equal proportion of soybean and lotus seeds could be a good option to prepare nutritious CGJ. © The Korean Society of Food Science and Technology | Jeon, Hyo-Won; Dhungana, Sanjeev Kumar; Kim, Il-Doo | Korea Natural Food Association, South Korea; Department of Southern Area Crop Science, National Institute of Crop Science, Rural Development Administration; International Institute of Agricultural Research and Development, Kyungpook National University, South Korea | 57223600068; 56269940800; 56269995600 | ildookim@hanmail.net; | Korean Journal of Food Science and Technology | 0367-6293 | 53 | 2 | 0 | 2025-07-30 | 0 | Antioxidant potential; Cheonggukjang; Lotus seed; Quality characteristic | English | Final | 2021 | 10.9721/kjfst.2021.53.2.126 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Quality characteristics of hot-air dried 'Darae' (Actinidia arguta) with different sugar osmotic dehydration pretreatment | In this study, various osmosis pretreatments were performed and the quality characteristics were compared in order to develop the optimal hot-air dried 'Darae' product. Treatment groups were osmoticized with sugar (SUC) and sorbitol (SOR), and were divided according to the presence or absence of ascorbic acid treatment at 30℃ and 55℃, respectively. The SOR groups showed high weight reduction (%) and low moisture content. Among the SUC groups the treatments added with ascorbic acid added at 55℃ showed high drying efficiency. The browning of fruits was more severe in the SOR, and as a result of the physical property analysis, the SUC tended to have a lower hardness and the flesh was soft. The total flavonoid contents and DPPH scavenging activity were high in the SUC groups, and especially the ascorbic acid treatment groups showed significantly higher antioxidant activity. Sensory evaluation showed that, there was no significant difference in sweetness or sourness, and in terms of appearance, SUC groups scored high. Therefore, it is appropriate to use an osmotic-dried solution of a 55℃ sugar osmosis solution added with ascorbic acid for manufacturing the optimal dried sputum with both palatability, functionality, and drying efficiency.

| ○ | Article | Quality characteristics of lotus root (Nelumbo nucifera G.) snacks according to heat treatment methods and conditions | This work investigated the effects of various heating methods and conditions on the quality characteristics of lotus root (Nelumbo nucifera G.) snack. The lotus root snacks were processed using the following heating methods: oven heating (OV), microwave heating (MW), air frying (AF), and oil frying (FR). Twenty four samples were prepared based on the various temperatures and time durations used for heating. Based on the results of color and hardness analyses, OV (180℃, 9 min), MW (850 W, 8 min), AF (120℃, 10 min) and FR (180℃, 70 sec) were selected as appropriate conditions for producing the lotus root snacks. AF resulted in low carbohydrate content, crude fat content, and neural detergent fiber content and the highest moisture content. There were no significant differences in hardness among four methods. AF (120℃, 10 min) showed significantly higher L* values, total phenolics contents, and 2,2-dipheny-1-picrylhydrazyl, 2,2'-azino-bis(3-ethylbenzothiazoline- 6-sulphonic acid radical scavenging activity than other methods. In addition, water absorption and water solubility indexes were the lowest in AF. Therefore, AF (120℃, 10 min) was considered as an appropriate heating condition for the manufacturing of lotus root snacks.

| ○ | Article | Quality characteristics of soft persimmon spread prepared with different functional saccharides | Soft persimmon spreads with four different functional saccharides were prepared for reducing the amount of excess sugar, and their quality characteristics were analyzed. CON1 had 40% sucrose added in weight, while CON2, XLT, IMO, FTO and MTD had 20% of sucrose, xylitol, isomalto-oligosaccharide, fructo-oligosaccharide, and maltodextrin added in weight, respectively. The proximate composition, soluble solid content, pH, total acidity, color, viscosity, tannin content, lycopene content, and glucose dialysis retardation index of the spreads with different saccharides were analyzed and compared. The proximate composition of the spreads was summarized as follows: 49-58% moisture, 0.29-0.58% crude protein, 0.02-0.10% crude fat, 0.32-0.37% crude ash, 40-50% carbohydrates, and 0.26-0.49% crude fiber. The total soluble solid of the spread containing IMO was 41.00 °Brix, which was significantly lower than that of the control spread (CON1) of 59.33 °Brix. The viscosity of the spread containing MTD was the highest, that is, 43,733 cp, while the spread with IMO had the lowest value of 17,600 cP. The content of lycopene in the spread with IMO was the highest as 58.99 mg/kg. The spread containing MTD indicated the most efficient glucose dialysis retardation index. There were no significant differences in the pH, total acidity, tannin content, color value, and sensory evaluation between the samples(p>0.05). Therefore, in terms of reducing sugar content in the spread, IMO exhibited the optimum result. Copyright © The Korean Society of Food Preservation.

| ○ | Article | Quality Control Methods for CTD Data Collected by Using Instrumented Marine Mammals: A Review and Case Study | ‘Marine mammals-based observations’ refers to data acquisition activities from marine mammals by instrumenting CTD (Conductivity-Temperature-Depth) sensors on them for recording vertical profiles of ocean variables such as temperature and salinity during animal diving. It is a novel data collecting platform that significantly improves our abilities in observing extreme environments such as the Southern Ocean with low cost compared to the other conventional methods. Furthermore, the system continues to create valuable information until sensors are detached, expanding data coverage in both space and time. Owing to these practical advantages, the marine mammals-based observations become popular to investigate ocean circulation changes in the Southern Ocean. Although these merits may bring us more opportunities to understand ocean changes, the data should be carefully qualified before we interpret it incorporating shipboard/autonomous vehicles/moored CTD data. In particular, we need to pay more attention to salinity correction due to the usage of an unpumped-CTD sensor tagged on marine mammals. In this article, we introduce quality control methods for the marine mammals-based CTD profiles that have been developed in recent studies. In addition, we discuss strategies of quality control specifically for the seal-tagging CTD profiles, successfully having been obtained near Terra Nova Bay, Ross Sea, Antarctica since February 2021. It is the Korea Polar Research Institute’s research initiative of animal-borne instruments monitoring in the region. We anticipate that this initiative would facilitate collaborative efforts among Polar physical oceanographers and even marine mammal behavior researchers to understand better rapid changes in marine environments in the warming world. © 2021, Korea Ocean Research and Development Institute.

| ○ | Article | Quantitative CT imaging and advanced visualization methods: Potential application in novel coronavirus disease 2019 (COVID-19) pneumonia | Increasingly, quantitative lung computed tomography (qCT)-derived metrics are providing novel insights into chronic inflammatory lung diseases, including chronic obstructive pulmonary disease, asthma, interstitial lung disease, and more. Metrics related to parenchymal, airway, and vascular anatomy together with various measures associated with lung function including regional parenchymal mechanics, air trapping associated with functional small airways disease, and dual-energy derived measures of perfused blood volume are offering the ability to characterize disease phenotypes associated with the chronic inflammatory pulmonary diseases. With the emergence of COVID-19, together with its widely varying degrees of severity, its rapid progression in some cases, and the potential for lengthy post-COVID-19 morbidity, there is a new role in applying well-established qCT-based metrics. Based on the utility of qCT tools in other lung diseases, previously validated supervised classical machine learning methods, and emerging unsupervised machine learning and deep-learning approaches, we are now able to provide desperately needed insight into the acute and the chronic phases of this inflammatory lung disease. The potential areas in which qCT imaging can be beneficial include improved accuracy of diagnosis, identification of clinically distinct phenotypes, improvement of disease prognosis, stratification of care, and early objective evaluation of intervention response. There is also a potential role for qCT in evaluating an increasing population of post-COVID-19 lung parenchymal changes such as fibrosis. In this work, we discuss the basis of various lung qCT methods, using case-examples to highlight their potential application as a tool for the exploration and characterization of COVID-19, and offer scanning protocols to serve as templates for imaging the lung such that these established qCT analyses have the best chance at yielding the much needed new insights. © 2021 The Authors. | Nagpal, Prashant; Guo, Junfeng; Shin, Kyung Min; Lim, Jae-Kwang; Kim, Ki Beom; Comellas, Alejandro P; Kaczka, David W; Peterson, Samuel; Lee, Chang Hyun; Hoffman, Eric A | Department of Radiology, University of Iowa, Carver College of Medicine, Iowa City, IA, United States; Department of Radiology, University of Iowa, Carver College of Medicine, Iowa City, IA, United States, Roy J.

| ○ | ○ | Article | Radiological Safety Assessment for a Near-Surface Disposal Facility Using RESRAD-ONSITE Code | Radiological impact analyses were carried out for a near-surface radioactive waste repository at Gyeongju in South Korea. The RESRAD-ONSITE code was applied for the estimation of maximum exposure doses by considering various exposure pathways based on a land area of 2,500 m(2) with a 0.15 m thick contamination zone. Typical influencing input parameters such as shield depth, shield materials' density, and shield erosion rate were examined for a sensitivity analysis. Then both residential farmer and industrial worker scenarios were used for the estimation of maximum exposure doses depending on exposure duration. The radiation dose evaluation results showed that Co-60, Cs-137, and Ni-63 were major contributors to the total exposure dose compared with other radionuclides. Furthermore, the total exposure dose from ingestion (plant, meat, and milk) of the contaminated plants was more significant than those assessed for inhalation, with maximum values of 5.5x10(-4) mSv.yr(-1) for the plant ingestion. Thus the results of this study can be applied for determining near-surface radioactive waste repository conditions and providing quantitative analysis methods using RESRAD-ONSITE code for the safety assessment of disposing radioactive materials including decommissioning wastes to protect human health and the environment. | Jang, Jiseon; Kim, Tae-Man; Cho, Chun-Hyung; Lee, Dae Sung | Korea Radioact Waste Agcy, 174 Gajeong Ro, Daejeon, South Korea; Kyungpook Natl Univ, 80 Daehak Ro, Daegu, South Korea | 56611137400; 57219319334; 57220796131; 55568524907 | skycho@korad.or.kr;daesung@knu.ac.kr; | JOURNAL OF NUCLEAR FUEL CYCLE AND WASTE TECHNOLOGY | 1738-1894 | 2288-5471 | 19 | 1 | 0.19 | 2025-07-30 | 3 | 3 | Radiation impact; Radioactive waste repository; Radionuclides; RESRAD; Safety assessment | Radiation impact; Radioactive waste repository; Radionuclides; RESRAD; Safety assessment | English | 2021 | 2021-03 | 10.7733/jnfcwt.2021.19.1.123 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | ○ | Proceedings Paper | Real Time Sensor Signal Processing Techniques Using Symmetric Dual-Bank Buffer on FreeRTOS | A real-time sensor device gets data from a sensor and transfers it to a host instantly. However, delay occurs at a microprocessor working on a single process when the transfer time is longer than the sensing period while executing the collecting and transferring of rotational data. Delay hinders the increase in the sampling rate of the device. In this paper, we suggest a technique for the short sampling period of a sensor device using FreeRTOS and multi-buffer. We execute sensing data and transfer data simultaneously in FreeRTOS. Prepare two buffers and save sensor data in rotation to avoid a collision of the sensing process and the transmission process. The Arduino Due collecting sensor data from 3 types of sensors reduces by 42% the sampling period with a symmetric dual-bank buffer algorithm. This algorithm is expected to enable microprocessors that can perform collect sensor data collection at high sampling rates. | Jung, Dongkyu; Park, Daejin | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57223051842; 55463943600 | boltanut@knu.ac.kr; | 2021 IEEE 3RD GLOBAL CONFERENCE ON LIFE SCIENCES AND TECHNOLOGIES (IEEE LIFETECH 2021) | 0.25 | 2025-07-30 | 0 | 1 | sensing device; high sampling rate; real-time sensor; FreeRTOS; multi-buffer | FreeRTOS; High sampling rate; Multi-buffer; Real-time sensor; Sensing device | Data acquisition; High sampling rates; Real time sensors; Rotational data; Sampling period; Sensing process; Sensor data collections; Short sampling period; Single process; Signal processing | English | 2021 | 2021 | 10.1109/lifetech52111.2021.9391911 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||
| ○ | Article | Real-time flood prediction applying random forest regression model in urban areas | Urban flooding caused by localized heavy rainfall with unstable climate is constantly occurring, but a system that can predict spatial flood information with weather forecast has not been prepared yet. The worst flood situation in urban area can be occurred with difficulties of structural measures such as river levees, discharge capacity of urban sewage, storage basin of storm water, and pump facilities. However, identifying in advance the spatial flood information can have a decisive effect on minimizing flood damage. Therefore, this study presents a methodology that can predict the urban flood map in real-time by using rainfall data of the Korea Meteorological Administration (KMA), the results of two-dimensional flood analysis and random forest (RF) regression model. The Ujeong district in Ulsan metropolitan city, which the flood is frequently occurred, was selected for the study area. The RF regression model predicted the flood map corresponding to the 50 mm, 80 mm, and 110 mm rainfall events with 6-hours duration. And, the predicted results showed 63%, 80%, and 67% goodness of fit compared to the results of two-dimensional flood analysis model. It is judged that the suggested results of this study can be utilized as basic data for evacuation and response to urban flooding that occurs suddenly. © 2021 Korea Water Resources Association. | Kim, Hyun Il; Lee, Yeon Su; Kim, Byunghyun | Nakdong River Flood Control Office, Busan, South Korea; Department of Civil Engineering, Kyungpook National University, Daegu, South Korea; Department of Civil Engineering, Kyungpook National University, Daegu, South Korea | 57205686299; 59221437100; 56097886500 | bhkimc@knu.ac.kr; | Journal of Korea Water Resources Association | 2799-8746 | 54 | S-1 | 0.15 | 2025-07-30 | 2 | Machine learning; Random forest; Real-time flood prediction; Urban flood | Korean | Final | 2021 | 10.3741/jkwra.2021.54.s-1.1119 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Real-Time Sound Event Classification for Human Activity of Daily Living using Deep Neural Network | Over the past years, increasing number of IoT sensors played important role in developing ambient assisted living (AAL) technologies such as elderly home care system by predicting activity of daily livings (ADLs). One way to develop smarter home care services with unobtrusive sensors in ubiquitous forms is using sound. This paper suggests a methodology to detect different sound events generated by residents based on real-life audio data. We propose a guide all the way from installing wireless microphone networks to recording, annotating, and preprocessing audios. Then we extract audio features and design deep learning classifier to classifying sound events. Finally, we deploy classifier on real-life scenarios to implement sound event detection in real-time. We evaluated 2D convolutional classifier with 16 sound events, achieving 95.55% training accuracy, 94.64% validation accuracy, 96.40% recall score, and 94.93% F1-score. | Yuh, Ah Hyun; Kang, Soon Ju | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 57557837600; 55666313900 | 0828lucy@gmail.com;sjkang@ee.knu.ac.kr; | IEEE CONGRESS ON CYBERMATICS / 2021 IEEE INTERNATIONAL CONFERENCES ON INTERNET OF THINGS (ITHINGS) / IEEE GREEN COMPUTING AND COMMUNICATIONS (GREENCOM) / IEEE CYBER, PHYSICAL AND SOCIAL COMPUTING (CPSCOM) / IEEE SMART DATA (SMARTDATA) | 0.54 | 2025-07-30 | 3 | 4 | Sound Event Classification; Audio Signal Processing; Activity of Daily Living; Deep Learning; Real Time System | Activity of Daily Living; Audio Signal Pro-cessing; Deep Learning; Real Time System; Sound Event Classification | Assisted living; Audio acoustics; Deep neural networks; Interactive computer systems; Activities of Daily Living; Ambient assisted living; Audio signal; Audio signal pro-cessing; Deep learning; Human activities; Real - Time system; Real time sound events; Sound event classification; Sound events; Real time systems | English | 2021 | 2021 | 10.1109/ithings-greencom-cpscom-smartdata-cybermatics53846.2021.00027 | 바로가기 | 바로가기 | 바로가기 |
