○ ○ Article ⓘ Blockchain-Enabled Key Aggregate Searchable Encryption Scheme for Personal Health Record Sharing With Multidelegation ⓘ The transition from patient-centered medical services to Health 5.0, which provides medical services to all customers using smart healthcare, has led to the use of the Internet of Things (IoT) for medical diagnosis and research based on the personal health records (PHRs) of service users. However, PHR contain sensitive personal information, which can cause privacy issues. Additionally, as emergencies may occur in real medical environments, multiauthority delegation must be considered. Although various methods are being studied for data sharing, they often do not meet the necessary security requirements in a real PHR sharing environment. In this study, we propose a system that uses key aggregate searchable encryption (KASE) to satisfy security requirements and leverages blockchain and smart contracts to improve data integrity, data audit records, and transparency. We also propose a method that ensures the data subject rights of PHR data owners when delegating multiple rights using attribute tokens. We conduct formal and informal security analyses to verify the robustness of the proposed system against potential adversarial attacks. Finally, a performance evaluation is conducted to verify the effectiveness of the proposed scheme. ⓘ Lee, JoonYoung; Oh, Jihyeon; Kwon, DeokKyu; Kim, Myeonghyun; Kim, Keonwoo; Park, Youngho ⓘ Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Cryptog & Authenticat Base Technol Res Sect, Daejeon 34129, South Korea ⓘ ; oh, jihyeon/JMQ-9587-2023 ⓘ 57203970123; 57222066296; 57221739597; 57210278739; 35205580200; 56962990300 ⓘ harry250@knu.ac.kr;chldlstnr071@knu.ac.kr;kdk145@knu.ac.kr;kimmyeong123@knu.ac.kr;wootopian@etri.re.kr;parkyh@knu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 10 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 2.78 2025-05-07 ⓘ 8 12 Cloud computing; Medical services; Access control; Smart contracts; Encryption; Servers; Data privacy; Blockchain (BC); key aggregate searchable encryption (KASE); multidelegation; personal health record (PHR) sharing; smart contract ⓘ WIRELESS SENSOR NETWORKS; SECURE; INTERNET ⓘ Blockchain (BC); key aggregate searchable encryption (KASE); multidelegation; personal health record (PHR) sharing; smart contract ⓘ Access control; Aggregates; Blockchain; Diagnosis; Internet of things; Sensitive data; Block-chain; Cloud-computing; Encryption schemes; Key aggregate searchable encryption; Medical services; Multi-delegation; Personal health record; Personal health record sharing; Searchable encryptions; Security requirements; Cryptography ⓘ English 2024 2024-05-15 10.1109/jiot.2024.3357802 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Cache-Assisted Mobile-Edge Computing Over Space-Air-Ground Integrated Networks for Extended Reality Applications ⓘ Extended reality-enabled Internet of Things (XRI) provides new user experiences and a sense of immersion by adding virtual elements to the real world through Internet of Things (IoT) devices and emerging sixth-generation (6G) technologies. However, computational-intensive XRI tasks are challenging for energy-constrained small-size XRI devices to cope with, and moreover certain data require centralized computing that needs to be shared among users. To this end, we propose a cache-assisted space-air-ground integrated network mobile-edge computing (SAGIN-MEC) system for XRI applications consisting of two types of edge servers mounted on an unmanned aerial vehicle (UAV) and low-Earth orbit (LEO) satellite equipped with a cache and multiple ground XRI devices. For system efficiency, four different offloading procedures of XRI data are considered according to the type of information, i.e., shared data and private data, as well as the offloading decision and the caching status. Specifically, private data can be offloaded to either UAV or LEO satellite, while the offloading decision of shared data to the LEO satellite can be determined by the caching status. With the aim of maximizing the energy efficiency of the overall system, we jointly optimize UAV trajectory, resource allocation, and offloading decisions under latency constraints and UAV's operational limitations by using the alternating optimization (AO)-based method along with the Dinkelbach algorithm and successive convex approximation (SCA). Via numerical results, the proposed algorithm is verified to have superior performance compared to conventional partial optimizations or processes without a cache. ⓘ Yoo, Seonghoon; Jeong, Seongah; Kim, Jeongbin; Kang, Joonhyuk ⓘ Korea Adv Inst Sci & Technol, Dept Elect Engn, Daejeon 34141, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 14566, South Korea ⓘ ⓘ 57847200000; 55210226900; 57865652100; 7404517651 ⓘ shyoo902@kaist.ac.kr;seongah@knu.ac.kr;kjungbin6560@kaist.ac.kr;jhkang@ee.kaist.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 10 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 6.25 2025-05-07 ⓘ 14 18 Low earth orbit satellites; Satellites; Autonomous aerial vehicles; Internet of Things; Servers; Task analysis; Energy efficiency; Cache; edge computing; extended reality (XR); Internet of Things (IoT); space-air-ground integrated network (SAGIN) ⓘ RESOURCE-ALLOCATION; COMMUNICATION; ARCHITECTURE; INTERNET; OPTIMIZATION; CLOUD ⓘ Cache; edge computing; extended reality (XR); Internet of Things (IoT); space-air-ground integrated network (SAGIN) ⓘ Antennas; Approximation algorithms; Computation offloading; Earth (planet); Internet of things; Job analysis; Mobile edge computing; Orbits; Satellites; Unmanned aerial vehicles (UAV); Aerial vehicle; Air grounds; Cache; Edge computing; Extended reality (XR); Integrated networks; Internet of thing; Low earth orbit satellites; Space-air-ground integrated network; Task analysis; Energy efficiency ⓘ English 2024 2024-05-15 10.1109/jiot.2024.3361907 ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ Comparative study on in-situ resilient modulus of subgrade estimated using in-situ modulus detector ⓘ This study presents a comprehensive evaluation of the resilient modulus of unsaturated subgrade soils using a novel in-situ modulus detector (IMD) along with various laboratory and field-testing methods. The current study employs several testing devices, including bender elements, standard dynamic cone penetrometer, and crossholetype dynamic cone penetrometer (CDP), to assess the reliability of the IMD in estimating the resilient modulus profiles of small-scale homogeneous subgrade models in unsaturated conditions. The index properties, compaction and strength characteristics of the compacted soils, are evaluated. The resilient modulus values obtained from the IMD are compared with those obtained from repeated load triaxial tests under various stress states. Experimental results show a decrease in the penetration depth per blow with increased dry unit weight. In addition, elastic modulus and shear wave velocity increase with soil density. The resilient modulus estimated from the IMD increase with both depth and soil density. A robust correlation has been established between the resilient modulus values estimated from the IMD and those estimated from the CDP or bender element tests. Furthermore, the resilient moduli estimated from the universal model and the IMD demonstrate linear relationships with a coefficient of determination greater than 0.8. Thus, the IMD may be useful for the in-situ evaluation of resilient modulus in unsaturated subgrade soils, considering influencing factors such as soil density and confining pressure. ⓘ Kim, Dong-Ju; Son, Dong Geon; Park, Geunwoo; Lee, Jong-Sub; Tutumluer, Erol; Byun, Yong-Hoon ⓘ Korea Univ, Sch Civil Environm & Architectural Engn, 145 Anam ro, Seoul 02841, South Korea; Univ Illinois Urbana & Champaign, Dept Civil & Environm Engn, 205 N Mathews Ave, Urbana, IL 61801 USA; Kyungpook Natl Univ, Dept Agr Civil Engn, 80 Daehak ro, Daegu 41566, South Korea ⓘ Lee, Jong-Sub/G-2752-2012; Tutumluer, Erol/O-2650-2019; Byun, Yong-Hoon/JKI-8441-2023 ⓘ 7409760881; 58490365100; 57216538003; 55690048400; 6603812780; 42761048000 ⓘ yhbyun@knu.ac.kr; ⓘ CONSTRUCTION AND BUILDING MATERIALS ⓘ CONSTR BUILD MATER ⓘ 0950-0618 1879-0526 442 SCIE CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 8 4.1 0.32 2025-05-07 ⓘ 2 2 In-situ test; Nondestructive testing; Pavement; Resilient modulus; Subgrade ⓘ DYNAMIC CONE PENETROMETER; PENETRATION; STRENGTH; LAYER ⓘ In-situ test; Nondestructive testing; Pavement; Resilient modulus; Subgrade ⓘ Shear flow; Shear waves; Soil testing; Soils; Wave propagation; Comparatives studies; Comprehensive evaluation; Dynamic cone penetrometer; In-situ test; Modulus values; Resilient modulus; Soil density; Subgrade; Subgrade soil; Type dynamics; Nondestructive examination ⓘ English 2024 2024-09-06 10.1016/j.conbuildmat.2024.137596 ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ Deep-Learning-Based Robust Channel Estimation for MIMO IoT Systems ⓘ When the second-order statistics of channel and noise, such as their covariance matrices, are not exactly known, the acquisition of accurate channel state information (CSI) for a wireless propagation environment becomes quite challenging. In this article, we tackle the problem of robust channel estimation for multiple-input-multiple-output (MIMO)-aided Internet of Things (IoT) systems in the presence of uncertainties in the channel and noise covariance matrices. Our goal is to minimize the mean square error (MSE) of the channel estimation under the channel and noise covariance uncertainties by jointly optimizing the channel estimator and pilot signal, which is however highly nonconvex and mathematically intractable. To effectively and intelligently cope with this issue, we exploit a deep learning (DL) technique and propose a novel network architecture with two modules, namely, the pilot optimizer and channel predictor, both of which are designed by neural networks with their own local connections and weight sharings. Moreover, a novel and effective training strategy for the proposed DL model is devised in a self-supervised manner, in which samples obtained by properly compensated channel and noise covariance matrices are utilized to overcome any adverse impacts of the underlying uncertainties on the channel estimation. Through extensive numerical results simulated in realistic propagation environments, we substantiate the superior performance and effectiveness of the proposed scheme. ⓘ Kang, Jae-Mo ⓘ Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea ⓘ ⓘ 56024930400 ⓘ jmkang@knu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 6 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 1.74 2025-05-07 ⓘ 3 6 Channel estimation; Covariance matrices; Uncertainty; Training; Deep learning; Massive MIMO; Signal design; covariance uncertainty; deep learning (DL); Internet of Things (IoT); multiple-input-multiple-output (MIMO); robust training design ⓘ TRAINING OPTIMIZATION; SIGNAL-DESIGN; PILOT DESIGN; POWER ⓘ Channel estimation; covariance uncertainty; deep learning (DL); Internet of Things (IoT); multiple-input-multiple-output (MIMO); robust training design ⓘ Channel state information; Covariance matrix; Deep learning; Internet of things; Mean square error; MIMO systems; Network architecture; Covariance matrices; Covariance uncertainties; Deep learning; Massive multiple-input multiple-output; Multiple inputs; Multiple outputs; Multiple-input multiple-output; Robust training design; Robust trainings; Signal design; Training design; Uncertainty; Channel estimation ⓘ English 2024 2024-03-15 10.1109/jiot.2023.3324667 ⓘ 바로가기 바로가기 바로가기 바로가기
○ Article ⓘ Design and Evaluation of a Cable-Actuated Palletizing Robot With Geared Rolling Joints ⓘ In the structure of a palletizing robot, auxiliary links are generally used to drive rotational links and maintain the horizontal orientation of the robot end-effector. However, with recent developments in manufacturing technologies and the increasing diversity of tasks, there is a demand for reducing the space occupied by auxiliary links with lightweight robot designs. In this article, a new method to reduce the size and weight of palletizing robots by replacing the existing auxiliary links with cable-actuation is proposed. First, the kinematics of a palletizing robot with parallelogram linkages based on geared rolling joints is explained. Additionally, the effects of multiple cable windings on the joint speed reduction are examined. A theoretical analysis of the relationship between the joint angle and cable length confirms that serially connected geared parallelograms can decouple joint motion. Furthermore, the effect of the cable length from the motor to the actuation joint on the stiffness is analyzed. Finally, experiments are conducted using a manufactured robot prototype to verify the effectiveness of cable windings, decoupled joint motion, and robot stiffness, and to confirm the accuracy of distal position and orientation. Consequently, the proposed cable-actuated palletizing robot is expected to be applied in various industrial robot designs. © 1996-2012 IEEE. ⓘ Choi, Wontae; Suh, Jungwook ⓘ Kyungpook National University (KNU), Department of Robot and Smart System Engineering, Daegu, 41566, South Korea; Kyungpook National University (KNU), Department of Robot and Smart System Engineering, Daegu, 41566, South Korea ⓘ ⓘ 58193290100; 36606826500 ⓘ jwsuh@knu.ac.kr; ⓘ IEEE/ASME Transactions on Mechatronics ⓘ IEEE-ASME T MECH ⓘ 1083-4435 1941-014X 29 4 SCIE AUTOMATION & CONTROL SYSTEMS;ENGINEERING, ELECTRICAL & ELECTRONIC;ENGINEERING, MANUFACTURING;ENGINEERING, MECHANICAL ⓘ 2024 7.3 4.1 0 2025-04-16 ⓘ 3 ⓘ ⓘ Actuation and joint mechanism; mechanism design; palletizing robot; rolling joint; tendon/wire mechanism ⓘ End effectors; Kinematics; Machine design; Stiffness; Winding; Actuation mechanism; Joint mechanism; Mechanical; Mechanical cable; Mechanism design; Palletizing robot; Robot kinematics; Rolling joints; Service robots; Tendon/wire mechanism; Cables ⓘ English Final 2024 10.1109/tmech.2024.3403131 ⓘ 바로가기 바로가기 바로가기

○ ○ Article ⓘ Effect of internal curing by superabsorbent polymers on the densification and microstructural development of cementitious materials exposed to different environmental conditions ⓘ Superabsorbent polymers (SAPs) are among the internal curing agents used in cementitious materials. This study aims to evaluate the influence of wider SAP dosages under different exposure environments on the micro -structural densification of cementitious materials and the development of strength and durability based on this. With SAP incorporation, hydrate crystallization most easily occurs in the wet/dry condition through hydration with externally supplied water and by internal SAP curing, which leads to the formation of the densest micro-structures. Microstructure densification further progresses as the SAP dosages increase. Despite the internal curing effect of SAPs, the ultrasonic pulse velocity and the compressive strength of S0.5 specimens compared with those of the REF specimens decrease due to SAP void presence. However, these mechanical properties of the S1.0 specimens are all recovered at later ages when exposed to the wet/dry condition, forming densest micro-structures. As the SAP dosages increase, the sealing effect of SAPs improves the water permeability characteristics at early ages. The lowest water permeability coefficient is observed in the S1.0 specimen exposed to the wet/dry condition as the further hydration effect of SAPs is exerted with increasing ages. In conclusion, utilizing the appropriate amount of SAPs and environmental conditions can effectively densify the internal pore structures, thereby securing the mechanical and durable properties of concrete structures. ⓘ Hong, Geuntae; Kim, Jiyoung; Song, Chiwon; Yeon, Jung Heum; Choi, Seongcheol ⓘ Kyungpook Natl Univ, Dept Civil Engn, 80 Daehak Ro, Daegu 41566, South Korea; Chung Ang Univ, Dept Civil & Environm Engn, 84 Heukseok Ro, Seoul 06974, South Korea; Smart Hitech Grp, Samsung Engn, 26 Sangil Ro 6 gil, Seoul 05288, South Korea; Hyundai Steel, Construct Steel Applicat Engn Team, 20,Pangyoyeok Ro 241beon Gil, Seongnam 13494, Gyeonggi Do, South Korea; Texas State Univ, Ingram Sch Engn, Civil Engn Program, 601 Univ Dr, San Marcos, TX 78666 USA ⓘ ; Choi, Seongcheol/AAV-1413-2020; Hong, Geuntae/AAM-8586-2020 ⓘ 57193714827; 57193279306; 56472191400; 35575468700; 35221260900 ⓘ schoi@cau.ac.kr; ⓘ CONSTRUCTION AND BUILDING MATERIALS ⓘ CONSTR BUILD MATER ⓘ 0950-0618 1879-0526 411 SCIE CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL;MATERIALS SCIENCE, MULTIDISCIPLINARY ⓘ 2024 8 4.1 2.53 2025-05-07 ⓘ 8 9 Compressive strength; Internal curing; Permeability; Microstructure; Superabsorbent polymer (SAP); Ultrasonic pulse velocity (UPV) ⓘ HIGH-PERFORMANCE CONCRETE; AUTOGENOUS SHRINKAGE; PORE STRUCTURE; WATER; PASTES; CRACKS; SAP; PERMEABILITY; COEFFICIENT; EVOLUTION ⓘ Compressive strength; Internal curing; Microstructure; Permeability; Superabsorbent polymer (SAP); Ultrasonic pulse velocity (UPV) ⓘ Curing; Densification; Hydration; Pore structure; Cementitious materials; Exposed to; Internal curing; Permeability; Polymer dosage; Superabsorbent polymer; Ultrasonic pulse velocity; Wet dries; Compressive strength ⓘ English 2024 2024-01-12 10.1016/j.conbuildmat.2023.134778 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Energy-Efficient Secure Offloading System Designed via UAV-Mounted Intelligent Reflecting Surface for Resilience Enhancement ⓘ With increasing interest in mmWave and THz communication systems, an unmanned aerial vehicle (UAV)-mounted intelligent reflecting surface (IRS) has been suggested as a key enabling technology to establish robust Line-of-Sight (LoS) connections with ground nodes owing to their free mobility and high altitude, especially for emergency and disaster response. This article investigates a secure offloading system, where the UAV-mounted IRS assists the offloading procedures between ground users and an access point (AP) acting as an edge cloud. In this system, the users except the intended recipients in the offloading process are considered as potential eavesdroppers. The system aims to achieve the minimum total energy consumption of battery-limited ground user devices under constraints for secure offloading accomplishment and operability of UAV-mounted IRS, which is done by optimizing the transmit power of ground user devices, the trajectory and phase shift matrix of UAV-mounted IRS, and the offloading ratio between local execution and edge computing based on the successive convex approximation (SCA) algorithms. Numerical results show that the proposed algorithm can provide the considerable energy savings compared with local execution and partial optimizations. ⓘ Kim, Doyoung; Jeong, Seongah; Kang, Jinkyu ⓘ Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Myongji Univ, Dept Informat & Commun Engn, Seoul 17058, Gyeonggi, South Korea ⓘ ; Jeong, Seongah/I-2863-2017; Kang, Joonhyuk/C-1771-2011; Jeong, Seongah/ABW-7285-2022 ⓘ 56802861000; 55210226900; 56283062100 ⓘ singha5036@knu.ac.kr;seongah@knu.ac.kr;jkkang@mju.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 3 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 1.74 2025-05-07 ⓘ 6 6 Communication; computing; edge computing; intelligent reflecting surface (IRS); physical-layer security; unmanned aerial vehicle (UAV) ⓘ OPTIMIZATION ⓘ Communication; computing; edge computing; intelligent reflecting surface (IRS); physical-layer security; unmanned aerial vehicle (UAV) ⓘ Antennas; Approximation algorithms; Edge computing; Emergency services; Energy efficiency; Internet of things; Network layers; Unmanned aerial vehicles (UAV); Aerial vehicle; Cloud-computing; Computing; Edge computing; Energy-consumption; Intelligent reflecting surface; Optimisations; Physical layer security; Reflecting surface; Unmanned aerial vehicle; Energy utilization ⓘ English 2024 2024-02-01 10.1109/jiot.2023.3336919 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Functional Outcomes Associated With Blood Pressure Decrease After Endovascular Thrombectomy ⓘ Importance The associations between blood pressure (BP) decreases induced by medication and functional outcomes in patients with successful endovascular thrombectomy remain uncertain. Objective To evaluate whether BP reductions induced by intravenous BP medications are associated with poor functional outcomes at 3 months. Design, Setting, and Participants This cohort study was a post hoc analysis of the Outcome in Patients Treated With Intra-Arterial Thrombectomy-Optimal Blood Pressure Control trial, a comparison of intensive and conventional BP management during the 24 hours after successful recanalization from June 18, 2020, to November 28, 2022. This study included 302 patients who underwent endovascular thrombectomy, achieved successful recanalization, and exhibited elevated BP within 2 hours of successful recanalization at 19 stroke centers in South Korea. Exposure A BP decrease was defined as at least 1 event of systolic BP less than 100 mm Hg. Patients were divided into medication-induced BP decrease (MIBD), spontaneous BP decrease (SpBD), and no BP decrease (NoBD) groups. Main Outcomes and Measures The primary outcome was a modified Rankin scale score of 0 to 2 at 3 months, indicating functional independence. Primary safety outcomes were symptomatic intracerebral hemorrhage within 36 hours and mortality due to index stroke within 3 months. Results Of the 302 patients (median [IQR] age, 75 [66-82] years; 180 [59.6%] men), 47 (15.6%)were in the MIBD group, 39 (12.9%) were in the SpBD group, and 216 (71.5%) were in the NoBD group. After adjustment for confounders, the MIBD group exhibited a significantly smaller proportion of patients with functional independence at 3 months compared with the NoBD group (adjusted odds ratio [AOR], 0.45; 95% CI, 0.20-0.98). There was no significant difference in functional independence between the SpBD and NoBD groups (AOR, 1.41; 95% CI, 0.58-3.49). Compared with the NoBD group, the MIBD group demonstrated higher odds of mortality within 3 months (AOR, 5.15; 95% CI, 1.42-19.4). The incidence of symptomatic intracerebral hemorrhage was not significantly different among the groups (MIBD vs NoBD: AOR, 1.89; 95% CI, 0.54-5.88; SpBD vs NoBD: AOR, 2.75; 95% CI, 0.76-9.46). Conclusions and Relevance In this cohort study of patients with successful endovascular thrombectomy after stroke, MIBD within 24 hours after successful recanalization was associated with poor outcomes at 3 months. These findings suggested lowering systolic BP to below 100 mm Hg using BP medication might be harmful. ⓘ Jung, Jae Wook; Kim, Kwang Hyun; Yun, Jaeseob; Kim, Young Dae; Heo, Joonnyung; Lee, Hyungwoo; Choi, Jin Kyo; Lee, Il Hyung; Lim, In Hwan; Hong, Soon-Ho; Kim, Byung Moon; Kim, Dong Joon; Shin, Na Young; Cho, Bang-Hoon; Ahn, Seong Hwan; Park, Hyungjong; Sohn, Sung-Il; Hong, Jeong-Ho; Song, Tae-Jin; Chang, Yoonkyung; Kim, Gyu Sik; Seo, Kwon-Duk; Lee, Kijeong; Chang, Jun Young; Seo, Jung Hwa; Lee, Sukyoon; Baek, Jang-Hyun; Cho, Han-Jin; Shin, Dong Hoon; Kim, Jinkwon; Yoo, Joonsang; Baik, Minyoul; Lee, Kyung-Yul; Jung, Yo Han; Hwang, Yang-Ha; Kim, Chi Kyung; Kim, Jae Guk; Lee, Chan Joo; Park, Sungha; Jeon, Soyoung; Lee, Hye Sun; Kwon, Sun U.; Bang, Oh Young; Heo, Ji Hoe; Nam, Hyo Suk ⓘ Yonsei Univ, Coll Med, Dept Neurol, 50-1 Yonsei Ro, Seoul 03722, South Korea; Yonsei Univ, Coll Med, Dept Radiol, Seoul, South Korea; Korea Univ, Anam Hosp, Coll Med, Seoul, South Korea; Coll Med, Seoul, South Korea; Chosun Univ, Sch Med, Dept Neurol, Gwangju, South Korea; Keimyung Univ, Brain Res Inst, Sch Med, Dept Neurol, Daegu, South Korea; Ewha Womans Univ, Seoul Hosp, Coll Med, Dept Neurol, Seoul, South Korea; Ewha Womans Univ, Coll Med, Mokdong Hosp, Dept Neurol, Seoul, South Korea; Ilsan Hosp, Natl Hlth Insurance Serv, Goyang, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Neurol, Seoul, South Korea; Inje Univ, Busan Paik Hosp, Coll Med, Dept Neurol, Busan, South Korea; Sungkyunkwan Univ, Sch Med, Kangbuk Samsung Hosp, Dept Neurol, Seoul, South Korea; Pusan Natl Univ, Sch Med, Dept Neurol, Busan, South Korea; Gachon Univ, Gil Med Ctr, Dept Neurol, Incheon 21565, South Korea; Yonsei Univ, Yongin Severance Hosp, Dept Neurol, Coll Med, Yongin, South Korea; Yonsei Univ, Coll Med, Gangnam Severance Hosp, Dept Neurol, Seoul, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Neurol, Daegu, South Korea; Korea Univ, Guro Hosp, Coll Med, Seoul, South Korea; Eulji Univ, Daejeon Eulji Med Ctr, Sch Med, Dept Neurol, Daejon, South Korea; Yonsei Univ, Severance Hosp, Coll Med, Dept Hlth Promot, Seoul, South Korea; Yonsei Univ, Cardiovasc Res Inst, Coll Med, Seoul, South Korea; Yonsei Univ, Coll Med, Dept Res Affairs, Biostat Collaborat Unit, Seoul, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med, Dept Neurol, Seoul, South Korea ⓘ kim, deog young/Q-8498-2019; Yun, Jaeseob/LOS-5991-2024; Kim, Dong/AAH-2257-2021; Lee, Il-Hyung/E-9712-2011; Lee, Kyung-Yeol/B-9978-2011; Lee, Hye Sun/J-2154-2015; Kim, Jinkwon/AAR-6729-2021; LEE, HYUN/ABC-6119-2021; CHIA, YOOK CHIN/B-8379-2010; Hong, Jeong-Ho/T-8099-2018; Heo, JoonNyung/ABI-5389-2020; Park, Hyungjong/AAI-5361-2020; Lee, HS/AAD-6757-2019; Kim, Eun/AAS-6706-2020; Kim, Jinkwon/N-1878-2018; Seo, Jung/N-2344-2017 ⓘ 57217003257; 57209600032; 58905434900; 57293047300; 57219861395; 57209973874; 57215910153; 57394223800; 57214234925; 58312729300; 49861594200; 57965484900; 56363572300; 55171752400; 57200401172; 57199865406; 36479287000; 55931654800; 55507164200; 56525550900; 58431244000; 57219304565; 58995258200; 56346807100; 55471870500; 57217310224; 56066538700; 57211361916; 57222389564; 37090736900; 55261162200; 57197951986; 57306378900; 57217582769; 7402311308; 56701057800; 56720623400; 57226133622; 8556278400; 57223622373; 57208650357; 7402624264; 7006620221; 34869576000; 58719143100 ⓘ hsnam@yuhs.ac; ⓘ JAMA NETWORK OPEN ⓘ JAMA NETW OPEN ⓘ 2574-3805 7 4 SCIE MEDICINE, GENERAL & INTERNAL ⓘ 2024 9.7 4.1 3.35 2025-05-07 ⓘ 5 4 ⓘ ACUTE ISCHEMIC-STROKE; BRAIN EDEMA; GUIDELINES ⓘ ⓘ Aged; Blood Pressure; Cerebral Hemorrhage; Cohort Studies; Female; Humans; Hypertension; Male; Pressure; Stroke; labetalol; nicardipine; aged; Article; blood pressure regulation; cohort analysis; confidence interval; depressed blood pressure; female; functional status; human; incidence; major clinical study; male; mortality; odds ratio; percutaneous thrombectomy; post hoc analysis; Rankin scale; recanalization; retrospective study; South Korea; systolic blood pressure; thrombectomy; treatment outcome; blood pressure; brain hemorrhage; cerebrovascular accident; hypertension; pressure ⓘ English 2024 2024-04-17 10.1001/jamanetworkopen.2024.6878 ⓘ 바로가기 바로가기 바로가기 바로가기

○ ○ Article ⓘ In-Vehicle Passenger Occupancy Detection Using 60-GHz FMCW Radar Sensor ⓘ Modern autonomous driving vehicles are equipped with a number of sensors to perceive the surrounding environment and enable automation of various systems. Especially, the passenger occupancy detection system can be utilized to detect a child left unattended in a parked vehicle, and efficiently manage the energy inside the vehicle. In this study, we propose a method of detecting the occupancy of passengers inside a vehicle using multichannel 60-GHz frequency-modulated continuous-wave (FMCW) radar. The received signal from the radar is converted into a range-angle map, and clutter suppression is performed to eliminate reflections from stationary objects. Then, by applying classification algorithms, such as the support vector machine (SVM), multilayer perceptron (MLP), and convolutional neural network (CNN), various arrangements of passengers inside a vehicle are identified. The classification results demonstrated that the proposed method can detect the location and number of passengers with an accuracy of 97.68%. ⓘ Lim, Sohee; Jung, Jaehoon; Lee, Eunji; Choi, Jeongsik; Kim, Seong-Cheol ⓘ Seoul Natl Univ, Dept Elect & Comp Engn, Seoul 08826, South Korea; Seoul Natl Univ, Inst New Media & Commun, Seoul 08826, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea ⓘ ; Choi, Jeongsik/ABA-6906-2020 ⓘ 57203931160; 59910980000; 57393526900; 58534394200; 22334016200 ⓘ gml0488@maxwell.snu.ac.kr;jeongsik.choi@knu.ac.kr;jay623@maxwell.snu.ac.kr;ej9309@maxwell.snu.ac.kr;sckim@maxwell.snu.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 4 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 1.39 2025-05-07 ⓘ 4 5 Radar; Radar detection; Chirp; Clutter; Radar imaging; Internet of Things; Feature extraction; Autonomous driving; clutter suppression; frequency-modulated continuous-wave (FMCW) radar; in-vehicle monitoring; passenger occupancy detection ⓘ MM-WAVE RADAR; LOCALIZATION ⓘ Autonomous driving; clutter suppression; frequency-modulated continuous-wave (FMCW) radar; in-vehicle monitoring; passenger occupancy detection ⓘ Autonomous vehicles; Clutter (information theory); Echo suppression; Frequency modulation; Multilayer neural networks; Radar clutter; Radar imaging; Support vector machines; Tracking radar; Autonomous driving; Chirp; Clutter; Clutter suppression; Features extraction; Frequency-modulated-continuous-wave radars; In-vehicle monitoring; Occupancy detections; Passenger occupancy detection; Radar detection; Vehicle monitoring; Feature extraction ⓘ English 2024 2024-02-15 10.1109/jiot.2023.3313357 ⓘ 바로가기 바로가기 바로가기 바로가기
○ ○ Article ⓘ Intelligent Packet Processing for Performant Containers in IoT ⓘ This article explores the computing and communication overhead of network processing in Internet of Things (IoT) devices, focusing on containers, a major building block for the edge computing. Our experiments reveal that containers on IoT devices suffer similar to 2.6 x higher CPU usage for SoftIRQ processing, similar to 59% less network throughput, and 2x higher per-packet latency on average than native processes. While several existing studies enhance networking performance, they often sacrifice interoperability by requiring special hardware or modifying networking semantics or APIs. Thus, we design and implement a kernel networking accelerator, called SCON, that maintains interoperability, crucial for IoT devices. SCON addresses major bottlenecks in container networking through system-level profiling. We evaluate SCON with three types of IoT devices. On the Raspberry Pi 4, SCON reduces the latencies of major IoT application protocols (e.g., HTTP and MQTT) by similar to 10 x , achieving a similar level of latency to the native process. Further analysis shows that SCON reduces CPU usage for SoftIRQ processing by similar to 26%. We also report similar improvements on the other two IoT devices. Our conclusion is that SCON is unique in significantly reducing the computing and communication overhead of container networking in IoT devices while maintaining interoperability. Furthermore, it works consistently across different types of devices, whether wired or wireless, and regardless of heavy or sporadic traffic. ⓘ Choi, Wonmi; Yoo, Yeonho; Lee, Kyungwoon; Niu, Zhixiong; Cheng, Peng; Xiong, Yongqiang; Yang, Gyeongsik; Yoo, Chuck ⓘ Korea Univ, Dept Comp Sci & Engn, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Microsoft Res Asia, Network infrastruct Grp, Beijing 100080, Peoples R China; Microsoft Res Asia, Vancouver Lab, Beijing 100080, Peoples R China ⓘ Lee, Kyungwoon/AGE-8826-2022; Yoo, Yeonho/LDF-2098-2024; Yang, Gyeongsik/X-2843-2019 ⓘ 59316406000; 57221232573; 57190025432; 57191093847; 58040448600; 35207647800; 57190761123; 7201746401 ⓘ ymcui@os.korea.ac.kr;yhyoo@os.korea.ac.kr;kwlee87@knu.ac.kr;zhniu@microsoft.com;pengc@microsoft.com;yqx@microsoft.com;g_yang@korea.ac.kr;chuckyoo@os.korea.ac.kr; ⓘ IEEE INTERNET OF THINGS JOURNAL ⓘ IEEE INTERNET THINGS ⓘ 2327-4662 11 24 SCIE ENGINEERING, ELECTRICAL & ELECTRONIC;TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS ⓘ 2024 8.9 4.1 0 2025-05-07 ⓘ 1 1 Internet of Things; Containers; IP networks; Performance evaluation; Kernel; Bridges; Throughput; Container virtualization; device virtualization; efficient communications and networking; real-time systems; resource-constrained networks ⓘ INTERNET; DEVICES; COMMUNICATION ⓘ Container virtualization; device virtualization; efficient communications and networking; real-time systems; resource-constrained networks ⓘ Edge computing; HTTP; Internet of things; Internet protocols; Interoperability; Packet networks; Virtualization; Communication overheads; Communications and networkings; Container virtualization; Device virtualization; Efficient communication and networking; Efficient communications; Real - Time system; Resource-constrained network; Virtualizations; Bottles ⓘ English 2024 2024-12-15 10.1109/jiot.2024.3453410 ⓘ 바로가기 바로가기 바로가기 바로가기
