| ○ | ○ | Article | Facile Surface Modification of Polyamide Membranes Using UV-Photooxidation Improves Permeability and Reduces Natural Organic Matter Fouling | A new optimized ultraviolet (UV) technique induced a photooxidation surface modification on thin-film composite (TFC) polyamide (PA) brackish water reverse osmosis (BWRO) membranes that improved membrane performance (i.e., permeability and organic fouling propensity). Commercial PA membranes were irradiated with UV-B light (285 nm), and the changes in the membrane performance were assessed through dead-end and cross-flow tests. UV-B irradiation at 12 J.cm(-2) enhanced the pure water permeability by 34% in the deadend tests without decreasing the mono- or divalent ion rejections, as compared with the pristine PA membrane, and led to less fouling by natural organic matter in the cross-flow tests. Scanning electron microscopy (SEM), attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, and X-ray photoelectron spectroscopy (XPS) confirmed that UV-B irradiation opened the pore structure and created carboxylic and amine groups on the PA surface, leading to increased membrane surface charge and hydrophilicity. Thus, an optimal UV-B dose appears to modify only a thin layer of the PA membrane surface, which favorably enhances the membrane performance. UV-B did not alter the structure, flux, or salt rejection for cellulose triacetate (CTA)-based membranes. While other membrane surface modifications include oxidants, strong acids, and bases, the UV-B facile treatment is chemical-free, thus reducing chemical wastes, and easy to apply in roll-to-roll fabrication processes of PA membranes. The results also showed that a low UV irradiation dose could be applied to PA or CTA membranes for disinfection or photocatalytic oxidation. | Rho, Hojung; Im, Sung-Ju; Alrehaili, Omar; Lee, Sungyun; Jang, Am; Perreault, Francois; Westerhoff, Paul | Arizona State Univ, Nanosyst Engn Res Ctr Nanotechnol Enabled Water T, Sch Sustainable Engn & Built Environm, Tempe, AZ 85287 USA; Korea Inst Civil Engn & Bldg Technol, Dept Land Water & Environm Res, Goyang Si 10223, Gyeonggi Do, South Korea; Sungkyunkwan Univ, Grad Sch Water Resources, Suwon 440746, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Disaster Prevent & Environm Engn, Dept Civil Environm Engn, Sangju Si 37224, Gyeongsangbuk D, South Korea | Alrehaili, Omar/GYQ-9674-2022; Perreault, François/C-9660-2012; Westerhoff, Paul/AAF-1850-2019; Rho, Hojung/AAZ-5517-2020 | 57196479406; 57184944200; 57216587263; 36438267000; 7004582729; 6507351085; 7004688700 | p.westerhoff@asu.edu; | ENVIRONMENTAL SCIENCE & TECHNOLOGY | ENVIRON SCI TECHNOL | 0013-936X | 1520-5851 | 55 | 10 | SCIE | ENGINEERING, ENVIRONMENTAL;ENVIRONMENTAL SCIENCES | 2021 | 11.357 | 7.7 | 1.36 | 2025-07-30 | 38 | 36 | desalination; fouling; membrane; water treatment; ultraviolet | X-RAY PHOTOELECTRON; THIN-FILM COMPOSITE; REVERSE-OSMOSIS; NANOFILTRATION MEMBRANE; FLUX DECLINE; CROSS-FLOW; WATER; PERFORMANCE; REMOVAL; CHARGE | desalination; fouling; membrane; ultraviolet; water treatment | Dosage; Fouling; Membranes; Organic Matter; Performance; Radiation Effects; Surfaces; Water Permeability; Filtration; Membranes, Artificial; Nylons; Osmosis; Permeability; Biogeochemistry; Chemical modification; Composite membranes; Fourier transform infrared spectroscopy; Irradiation; Organic compounds; Photooxidation; Pore structure; Scanning electron microscopy; X ray photoelectron spectroscopy; amine; aromatic polyamide; brackish water; cellulose triacetate; natural organic matter; oxidizing agent; polyamide; nylon; Attenuated total reflection fourier transform infrared; Brackish water reverse osmosis; Membrane surface charge; Membrane surface modifications; Natural organic matter fouling; Photocatalytic oxidations; Pure water permeabilities; Roll-to-roll fabrication; fouling; membrane; organic matter; permeability; photooxidation; ultraviolet radiation; Article; atomic force microscopy; attenuated total reflectance Fourier transform infrared spectroscopy; chemical composition; chemical structure; desalination; disinfection; hydrophobicity; hyperbarism; membrane permeability; membrane resistance; photooxidation; polarization; scanning electron microscopy; surface property; ultraviolet B radiation; water permeability; water treatment; X ray photoemission spectroscopy; artificial membrane; filtration; osmosis; permeability; Osmosis membranes | English | 2021 | 2021-05-18 | 10.1021/acs.est.0c07844 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Tunicate-Inspired Photoactivatable Proteinic Nanobombs for Tumor-Adhesive Multimodal Therapy | Near-IR (NIR) light-responsive multimodal nanotherapeutics have been proposed to achieve improved therapeutic efficacy and high specificity in cancer therapy. However, their clinical application is still elusive due to poor biometabolization and short retention at the target site. Here, innovative photoactivatable vanadium-doped adhesive proteinic nanoparticles (NPs) capable of allowing biological photoabsorption and NIR-responsive anticancer therapeutic effects to realize trimodal photothermal-gas-chemo-therapy treatments in a highly biocompatible, site-specific manner are proposed. The photoactivatable tumor-adhesive proteinic NPs can enable efficient photothermal conversion via tunicate-inspired catechol-vanadium complexes as well as prolonged tumor retention by virtue of mussel protein-driven distinctive adhesiveness. The incorporation of a thermo-sensitive nitric oxide donor and doxorubicin into the photoactivatable adhesive proteinic NPs leads to synergistic anticancer therapeutic effects as a result of photothermal-triggered "bomb-like" multimodal actions. Thus, this protein-based phototherapeutic tumor-adhesive NPs have great potential as a spatiotemporally controllable therapeutic system to accomplish effective therapeutic implications for the complete ablation of cancer. | Jeong, Yeonsu; Jo, Yun Kee; Kim, Mou Seung; Joo, Kye Il; Cha, Hyung Joon | Pohang Univ Sci & Technol, Dept Chem Engn, Pohang 37673, South Korea; Kyungpook Natl Univ, Sch Convergence, Dept Biomed Convergence Sci & Technol, Daegu 41566, South Korea; Kyungpook Natl Univ, Cell & Matrix Res Inst, Daegu 41566, South Korea; Ewha Womans Univ, Div Chem Engn & Mat Sci, Seoul 03760, South Korea | Joon, Hyung/AAO-8422-2020 | 57203275643; 56123757800; 57298073800; 21739452800; 55954303800 | hjcha@postech.ac.kr; | ADVANCED HEALTHCARE MATERIALS | ADV HEALTHC MATER | 2192-2640 | 2192-2659 | 10 | 23 | SCIE | ENGINEERING, BIOMEDICAL;MATERIALS SCIENCE, BIOMATERIALS;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 11.092 | 7.7 | 0.49 | 2025-07-30 | 9 | 11 | bioinorganic chemistry; multimodal anticancer therapy; NIR-responsive nanotherapeutics; protein-based photothermal agents; vanadium-doping effect | NITRIC-OXIDE; PHOTOTHERMAL THERAPY; METAL-COMPLEXES; NANOPARTICLES; RELEASE; ELECTROCHEMILUMINESCENCE; COMBINATION; FLUORESCENT; RESISTANCE; POLYMERS | bioinorganic chemistry; multimodal anticancer therapy; NIR-responsive nanotherapeutics; protein-based photothermal agents; vanadium-doping effect | Adhesives; Animals; Cell Line, Tumor; Doxorubicin; Hyperthermia, Induced; Nanoparticles; Neoplasms; Phototherapy; Urochordata; Adhesives; Biochemistry; Biocompatibility; Diseases; Infrared devices; Nitric oxide; Tumors; Vanadium compounds; adhesive agent; doxorubicin; nanoparticle; Anti-cancer therapies; Bioinorganic chemistry; Doping effects; Multi-modal; Multimodal anticancer therapy; Near-IR; Near-IR-responsive nanotherapeutic; Photo-thermal; Protein-based photothermal agent; Vanadium doping; Vanadium-doping effect; animal; neoplasm; phototherapy; thermotherapy; tumor cell line; Urochordata; Proteins | English | 2021 | 2021-12 | 10.1002/adhm.202101212 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Does employee satisfaction influence customer satisfaction? Assessing coffee shops through the service profit chain model | This study examines the interrelations between service climate, organizational identification, employee job satisfaction, and customer perceived value and satisfaction. To achieve this, we apply the service profit chain model to South Korea's coffee shop industry. Data were collected from 263 employees and 973 customers in Daegu. The hypotheses were tested by conducting a path analysis to investigate the relationship between the variables. Organizational identification and job satisfaction were found to be positively correlated with each other. Additionally, job satisfaction was correlated with customer perceived value, which, in turn, was correlated with customer satisfaction. The findings suggest that a good work environment and service-related training can create a positive service climate for employees, which can subsequently improve customer satisfaction. This study is unique in its application of the service profit chain model on the coffee shop industry in Korea. | Son, Jung Hee; Kim, Jae Hong; Kim, Gi Jin | Woosuk Univ, Dept Global Food Serv Management, Jeonju, South Korea; Kyungpook Natl Univ, Dept Econ & Business Adm, Daegu, South Korea; Yeungnam Univ, Dept Food Serv Ind, Daegu, South Korea | Kim, Jinyoung/LFS-2554-2024 | 57221819499; 57221817660; 55850123700 | 987307@hanmail.net; | INTERNATIONAL JOURNAL OF HOSPITALITY MANAGEMENT | INT J HOSP MANAG | 0278-4319 | 1873-4693 | 94 | SSCI | HOSPITALITY, LEISURE, SPORT & TOURISM | 2021 | 10.427 | 7.8 | 1.73 | 2025-07-30 | 31 | 36 | Service climate; Employee satisfaction; Customer satisfaction; Service profit chain model; Coffee shop industry; Korea | PERCEIVED EXTERNAL PRESTIGE; ORGANIZATIONAL IDENTIFICATION; JOB-SATISFACTION; SATISFIED CUSTOMERS; QUALITY; LOYALTY; CLIMATE; IMPACT; PERFORMANCE; COMMUNICATION | Coffee shop industry; Customer satisfaction; Employee satisfaction; Korea; Service climate; Service profit chain model | English | 2021 | 2021-04 | 10.1016/j.ijhm.2021.102866 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Investigating beliefs, attitudes, and intentions regarding green restaurant patronage: An application of the extended theory of planned behavior with moderating effects of gender and age | This study aims to identify customer belief structures underlying the cognitive process of green restaurant patronage by applying the extended theory of planned behavior (TPB). The extended TPB model includes two additional predictors (past behavior and dining frequency) and two moderators (gender and age) to predict customers' intention to visit green restaurants. This study followed recommended two-phase survey procedures. Salient beliefs of the target population were elicited in the first phase, and the relationships between those beliefs and other TPB constructs were analyzed in the second phase. Perceived behavioral control emerged as the most significant determinant followed by attitude and subjective norm in the Korean green restaurant context. The findings support the inclusion of past behavior as an additional predictor and confirm the moderating effects of gender and age. This study provides useful implications for effective marketing strategies for green restaurants. | Moon, Sun-Jung | Kyungpook Natl Univ, Sch Business Adm, 80 Daehakro, Daegu 41566, South Korea | 57197870440 | sjmoon925@naver.com; | INTERNATIONAL JOURNAL OF HOSPITALITY MANAGEMENT | INT J HOSP MANAG | 0278-4319 | 1873-4693 | 92 | SSCI | HOSPITALITY, LEISURE, SPORT & TOURISM | 2021 | 10.427 | 7.8 | 6.33 | 2025-07-30 | 132 | 149 | Green restaurant; Intention; Attitudes; Past behavior; Beliefs; Theory of planned behavior | PAST BEHAVIOR; ENVIRONMENTAL CONCERN; CONSUMERS; FOOD; DETERMINANTS; DEMOGRAPHICS; ATTRIBUTES; CHOICE; ROLES; MODEL | Attitudes; Beliefs; Green restaurant; Intention; Past behavior; Theory of planned behavior | English | 2021 | 2021-01 | 10.1016/j.ijhm.2020.102727 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Pinging the brain with transcranial magnetic stimulation reveals cortical reactivity in time and space | Background: Single-pulse transcranial magnetic stimulation (TMS) elicits an evoked electroencephalography (EEG) potential (TMS-evoked potential, TEP), which is interpreted as direct evidence of cortical reactivity to TMS. Thus, combining TMS with EEG can be used to investigate the mechanism underlying brain network engagement in TMS treatment paradigms. However, controversy remains regarding whether TEP is a genuine marker of TMS-induced cortical reactivity or if it is confounded by responses to peripheral somatosensory and auditory inputs. Resolving this controversy is of great significance for the field and will validate TMS as a tool to probe networks of interest in cognitive and clinical neuroscience. Objective: Here, we delineated the cortical origin of TEP by spatially and temporally localizing successive TEP components, and modulating them with transcranial direct current stimulation (tDCS) to investigate cortical reactivity elicited by single-pulse TMS and its causal relationship with cortical excitability. Methods: We recruited 18 healthy participants in a double-blind, cross-over, sham-controlled design. We collected motor-evoked potentials (MEPs) and TEPs elicited by suprathreshold single-pulse TMS targeting the left primary motor cortex (M1). To causally test cortical and corticospinal excitability, we applied tDCS to the left M1. Results: We found that the earliest TEP component (P25) was localized to the left M1. The following TEP components (N45 and P60) were largely localized to the primary somatosensory cortex, which may reflect afferent input by hand-muscle twitches. The later TEP components (N100, P180, and N280) were largely localized to the auditory cortex. As hypothesized, tDCS selectively modulated cortical and corticospinal excitability by modulating the pre-stimulus mu-rhythm oscillatory power. Conclusion: Together, our findings provide causal evidence that the early TEP components reflect cortical reactivity to TMS. (c) 2021 The Author(s). Published by Elsevier Inc.

| ○ | ○ | Article | Application of conditional generative model for sonic log estimation considering measurement uncertainty | Well-log data is a cost-effective means to characterize the petrophysical properties of a geological formation. Among the data, compressional- and shear-slowness (DTC and DTS, respectively) are the most reliable and have been widely applied in the interpretations. However, the availability of DTS data tends to be limited because of its high acquisition cost. This study proposes a method to reproduce or reconstruct the DTS data using other well-log data, such as gamma ray, neutron porosity, bulk density, and DTC. The developed method is based on the conditional variational autoencoder (CVAE) and effectively considers uncertainty associated with the variability of the measured data. The performance of this developed method is validated by applying the well-log data acquired from Satyr-5 and Callihoe-1 wells in the Northern Carnarvon Basin, Western Australia, and the prediction accuracy of the developed method is compared to recently developed data-driven methods (i.e., long short-term memory (LSTM) and bidirectional LSTM (bi-LSTM)). The results reveal that the developed method produces a better DTS estimation than LSTM and bi-LSTM. Furthermore, the effectiveness of the proposed method remains unaltered regardless of whether the data contain a specific trend over the depth or amount of training data are insufficient. As a further application of the developed method, an uncertainty relative to DTS estimation is quantitatively obtained from Monte-Carlo estimation, which uses a trained probability model of the developed method. Sensitivity analysis reveals the high effectiveness of DTC in improving the performance of the CVAE method. From our results, we can conclude that the proposed CVAE-based method is an effective tool for improving the efficiency and accuracy of DTS estimation. | Jeong, Jina; Park, Eungyu; Emelyanova, Irina; Pervukhina, Marina; Esteban, Lionel; Yun, Seong-Taek | Kyungpook Natl Univ, Dept Geol, Daegu, South Korea; Commonwealth Sci & Ind Res Org CSIRO, Energy, Perth, WA, Australia; Korea Univ, Earth & Environm Sci, 145 Anam Ro, Seoul 02841, South Korea | ; Emelyanova, Irina/F-7743-2011 | 55488558800; 23995577700; 23501352100; 24339119300; 16039005100; 57221362072 | egpark@knu.ac.kr; | JOURNAL OF PETROLEUM SCIENCE AND ENGINEERING | J PETROL SCI ENG | 0920-4105 | 1873-4715 | 196 | SCIE | ENERGY & FUELS;ENGINEERING, PETROLEUM | 2021 | 5.168 | 7.9 | 0.87 | 2025-07-30 | 14 | 14 | Well-log estimation; Long short-term memory (LSTM); Bi-direction LSTM (Bi-LSTM); Conditional variational autoencoder; Probabilistic estimation; Sensitivity analysis | SHEAR-WAVE VELOCITY; WELL LOG; NEURAL-NETWORK; ROCK-PHYSICS; PREDICTION; RESERVOIR; LITHOLOGY; ALGORITHM | Bi-direction LSTM (Bi-LSTM); Conditional variational autoencoder; Long short-term memory (LSTM); Probabilistic estimation; Sensitivity analysis; Well-log estimation | Australia; Carnarvon Basin; Western Australia; Cost effectiveness; Gamma rays; Monte Carlo methods; Neutron logging; Petrophysics; Sensitivity analysis; Uncertainty analysis; Cost-effective means; Data-driven methods; Geological formation; Measurement uncertainty; Monte-Carlo estimation; Petrophysical properties; Prediction accuracy; Probability modeling; compression; estimation method; Monte Carlo analysis; petrography; probability; sensitivity analysis; sonic boom; uncertainty analysis; Long short-term memory | English | 2021 | 2021-01 | 10.1016/j.petrol.2020.108028 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Estimation and uncertainty analysis of the CO2 storage volume in the sleipner field via 4D reversible-jump markov-chain Monte Carlo | Many scientists have developed technology to store CO2 in the subsurface and to monitor the storage conditions to comply with the requirements for zero detectable leakage and greenhouse gas control. The goal of this research is to propose a novel workflow to estimate the stored CO2 volume and to quantify the uncertainty of the injected volume. We implemented geophysical stochastic inversion using the time-lapse 3D seismic volumes as inputs, which provides an indirect estimation of the velocity changes and the migration path of the injected gas content. When performing the inversion, we employed the reversible-jump approach and used the Sleipner time-lapse 3D seismic volumes to demonstrate the proposed workflow. The inversion result was validated via forward modeling and pseudo well log interpretation. We then built a structural geology model and populated porosity logs by performing 500 realizations for volumetric analysis. In a comparison of the measured volume of the injected gas via volumetric analysis results, the predicted subsurface CO2 volume linearly increases in the same phase with the injection rate, and the volume estimation error is less than 17%. | Cho, Yongchae; Jun, Hyunggu | Shell Int Explorat & Prod Inc, 150 N Dairy Ashford Rd, Houston, TX 77079 USA; Korea Inst Ocean Sci & Technol, 385 Haeyang Ro, Busan 49111, South Korea; Kyungpook Natl Univ, 80 Daehak Ro, Daegu 41566, South Korea | Cho, Yongchae/AAA-7647-2021; Jun, Hyunggu/ABT-7172-2022 | 55513719100; 56048061400 | hgjun1026@kiost.ac.kr; | JOURNAL OF PETROLEUM SCIENCE AND ENGINEERING | J PETROL SCI ENG | 0920-4105 | 1873-4715 | 200 | SCIE | ENERGY & FUELS;ENGINEERING, PETROLEUM | 2021 | 5.168 | 7.9 | 0.8 | 2025-07-30 | 18 | 15 | Carbon capture and sequestration; Time-lapse monitoring; Markov-chain Monte Carlo; Uncertainty analysis; Volume estimation | Carbon capture and sequestration; Markov-chain Monte Carlo; Time-lapse monitoring; Uncertainty analysis; Volume estimation | Atlantic Ocean; North Sea; Sleipner Field; Varanidae; Carbon dioxide; Greenhouse gases; Markov chains; Seismology; Stochastic systems; Structural geology; Volumetric analysis; Well logging; Forward modeling; Injection rates; Inversion results; Reversible jump; Reversible jump Markov chain Monte Carlo; Storage condition; Velocity changes; Volume estimations; carbon sequestration; estimation method; greenhouse gas; Markov chain; Monte Carlo analysis; numerical model; three-dimensional modeling; uncertainty analysis; Uncertainty analysis | English | 2021 | 2021-05 | 10.1016/j.petrol.2020.108333 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | I/Q Imbalance Aware Nonlinear Wireless-Powered Relaying of B5G Networks: Security and Reliability Analysis | Physical layer security is known as a promising paradigm to ensure secure performance for the future beyond 5G (B5G) networks. In light of this fact, this paper elaborates on a tractable analysis framework to evaluate the reliability and the security of wireless-powered decode-and-forward (DF) multi-relay networks. More practical, the nonlinear energy harvesters, in-phase and quadrature-phase imbalance (IQI) and channel estimation errors (CEEs) are taken into account. To further enhance the secure performance, two relay selection strategies are presented: 1) suboptimal relay selection (SRS); 2) optimal relay selection (ORS). Specifically, exact analytical expressions for the outage probability (OP) and the intercept probability (IP) are derived in closed-form. For the IP, we consider that the eavesdropper can wiretap the signal from the source or the relay. In order to obtain more deep insights, we carry out the asymptotic analysis as well as the diversity orders for the OP in the high signal-to-noise ratio (SNR) regimes. Numerical results show that: 1) Although the mismatches of amplitude/phase of transmitter (TX)/receiver (RX) limit the OP performance, it can enhance IP performance; 2) Large number of relays yields better OP performance; 3) There are error floors for the OP due to the CEEs; 4) There is a trade-off for the OP and IP to obtain the balance between reliability and security. | Li, Xingwang; Huang, Mengyan; Liu, Yuanwei; Menon, Varun G.; Paul, Anand; Ding, Zhiguo | Henan Polytech Univ, Sch Phys & Elect Informat Engn, Jiaozuo 454000, Henan, Peoples R China; Queen Mary Univ London, Sch Elect Engn & Comp Sci, London E1 4NS, England; SCMS Sch Engn & Technol, Dept Comp Sci & Engn, Ernakulam 683576, India; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 702701, South Korea; Univ Manchester, Sch Elect & Elect Engn, Manchester M13 9PL, Lancs, England | Li, Xingwang/Q-8156-2017; Li, Xingwang/K-8678-2019; Liu, Yuanwei/AAA-2444-2020; Menon, Varun G/G-9841-2016; Paul, Anand/V-6724-2017; Menon, Varun/G-9841-2016 | 56152312500; 57201727914; 56454483900; 55765379100; 56650522400; 57226326300 | lixingwangbupt@gmail.com;huangmengyan66@163.com;yuanwei.liu@qmul.ac.uk;varunmenon@ieee.org;paul.editor@gmail.com;zhiguo.ding@manchester.ac.uk; | IEEE TRANSACTIONS ON NETWORK SCIENCE AND ENGINEERING | IEEE T NETW SCI ENG | 2327-4697 | 8 | 4 | SCIE | ENGINEERING, MULTIDISCIPLINARY;MATHEMATICS, INTERDISCIPLINARY APPLICATIONS | 2021 | 5.033 | 7.9 | 2.99 | 2025-07-30 | 60 | 52 | Relays; Security; Channel estimation; Fading channels; IP networks; Signal to noise ratio; Wireless communication; Energy harvesting; Physical layer; B5G; channel estimation error; in-phase and quadrature-phase imbalance; nonlinear energy harvester; physical layer security | PHYSICAL-LAYER SECURITY; PERFORMANCE ANALYSIS; COOPERATIVE DIVERSITY; RESOURCE-ALLOCATION; SELECTION; INFORMATION; SYSTEMS; OUTAGE; NOMA; LTE | B5G; channel estimation error; in-phase and quadrature-phase imbalance; nonlinear energy harvester; physical layer security. | 5G mobile communication systems; Asymptotic analysis; Channel estimation; Economic and social effects; Errors; Internet protocols; Network layers; Network security; Nonlinear analysis; Reliability analysis; Signal to noise ratio; Beyond 5g; Channel estimation error; Energy Harvester; Estimation errors; In-phase and quadrature-phase imbalances; Nonlinear energy harvester; Outage probability; Physical layer security; Physical layer security.; Relay selection; Energy harvesting | English | 2021 | 2021-10-01 | 10.1109/tnse.2020.3020950 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Secure and Efficient Honey List-Based Authentication Protocol for Vehicular Ad Hoc Networks | Vehicular Ad Hoc Network (VANET) and Internet of Vehicle (IoV) technologies are particularly attracting attention from industrial communities because of the intelligent transportation systems of smart city technologies. Vehicle-to-vehicle (V2V) communication of VANET can guarantee traffic system management and road safety. However, V2V communication cannot manage many vehicles as a whole, so it needs to be segmented and communicated by region. Therefore, considering locality, key agreement is made for V2V communication of the same or different regions. Moreover, traditional public key infrastructure (PKI) and Kerberos systems to be applied in a real environment incur computational overhead. Therefore, we proposed a lightweight protocol for dynamic properties of vehicles for regional segmentation management and overhead resolution. In addition, because vehicle information is transmitted through public channels, our protocol uses mutual authentication and honeyₗᵢₛₜ technology to ensure security against a variety of attacks. It provides verification of safety through a detailed security analysis using the formal analysis using the widely-accepted Real-Or-Random (ROR) model, and verifies formal security using the Automated Validation of Internet Security Protocols and Applications (AVISPA) software tool and non-mathematical (informal) security analysis. In addition, a detailed comparative study that the proposed scheme can be applied in the communication environment between actual vehicles as compared to other existing competing schemes. | Lee, JoonYoung; Kim, GeonHwan; Das, Ashok Kumar; Park, YoungHo | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Int Inst Informat Technol, Ctr Secur Theory & Algorithm Res, Hyderabad 500032, India | Lee, JoonYoung/AAM-9838-2021; Das, Ashok Kumar/U-2790-2019 | 57203970123; 57189040274; 55450732800; 56962990300 | harry250@knu.ac.kr;kgh76@ee.knu.ac.kr;iitkgp.akdas@gmail.com;parkyh@knu.ac.kr; | IEEE TRANSACTIONS ON NETWORK SCIENCE AND ENGINEERING | IEEE T NETW SCI ENG | 2327-4697 | 8 | 3 | SCIE | ENGINEERING, MULTIDISCIPLINARY;MATHEMATICS, INTERDISCIPLINARY APPLICATIONS | 2021 | 5.033 | 7.9 | 3.56 | 2025-07-30 | 37 | 69 | Protocols; Authentication; Security; Vehicular ad hoc networks; Wireless communication; Password; Smart cities; Internet of Vehicles (IoV); communication; security; mutual authentication; AVISPA; ROR model; Honey list | KEY MANAGEMENT PROTOCOL; USER AUTHENTICATION; AGREEMENT SCHEME; INTERNET; CHALLENGES; DESIGN | AVISPA; communication; Honey list.; Internet of Vehicles (IoV); mutual authentication; ROR model; security | Application programs; Authentication; Highway planning; Intelligent systems; Internet protocols; Motor transportation; Security systems; Vehicle to vehicle communications; Vehicles; Vehicular ad hoc networks; Verification; Authentication and key agreement protocols; Authentication protocols; Communication environments; Comparative studies; Intelligent transportation systems; Lightweight protocols; Mutual authentication; Software validation; Network security | English | 2021 | 2021 (JUL-SEP) | 10.1109/tnse.2021.3093435 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | The relationship between consumer engagements with Super Bowl ad tweets and the advertisers' official Twitter accounts: a panel data analysis of 2019 Super Bowl advertisers | This study aims to examine the influence of consumer engagement with Super Bowl ad tweets, on their engagement with the advertiser's official Twitter account. Using Python, audience engagement data were collected from the Super Bowl advertisers' official Twitter accounts on a daily basis from two days before the game until 10 days after the game; this procedure resulted in 351 cases for 27 advertisers in a balanced panel dataset. Overall, the results of panel regression analyses employing a feasible generalized least squares (FGLS) procedure and panel-corrected standard error (PCSE) estimates support the hypothesis predicting transference of engagement from Super Bowl ads tweets to the advertisers' official Twitter accounts. In particular, of the three engagement metrics, the number of retweets of and favorites on the Super Bowl ad tweets significantly increased the numbers of followers and favorites on the official Twitter accounts of the Super Bowl advertisers. The theoretical and managerial implications of the findings are discussed. | Noh, Yeayoung; Kim, Hyuksoo; Kim, Kihan; Cheong, Yunjae | Seoul Natl Univ, Seoul, South Korea; Seoul Natl Univ, Sport Management, Seoul, South Korea; Kyungpook Natl Univ, Sch Business Adm, Daegu, South Korea; Hankuk Univ Foreign Studies, Sch Media Commun, Seoul, South Korea | 57219292673; 57110953000; 35751379100; 28767587800 | cheong@hufs.ac.kr; | INTERNATIONAL JOURNAL OF ADVERTISING | INT J ADVERT | 0265-0487 | 1759-3948 | 40 | 6 | SSCI | BUSINESS;COMMUNICATION | 2021 | 5.888 | 7.9 | 0.56 | 2025-07-30 | 11 | 10 | Super Bowl ad; brand engagement; Twitter; social media; panel data analysis; Python | INFORMATION | brand engagement; panel data analysis; Python; social media; Super Bowl ad; Twitter | English | 2021 | 2021-08-19 | 10.1080/02650487.2020.1819006 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Understanding the role of construal level in time-restriction | Understanding how time restriction impacts consumers has been an important long-term topic for both scholars and practitioners. Applying a Construal Level Theory framework, two experiments were designed to propose a new theoretical perspective regarding the mechanism of time restriction. Testing moderators of advertising appeals and message quality, the study aimed to identify the conditions under which time restriction is more effective in influencing consumers’ response. In study 1, a factorial 2 × 2 design (time restriction: yes vs. no x advertising appeal: collectivistic vs. individualistic) between subjects was employed using a student sample and a high-involvement product. In study 2, another factorial 2 × 2 design (time restriction: yes vs. no x advertising appeal: guilt vs. shame) between subjects was employed using a general population and a low-involvement product. The findings of the two studies confirmed the mediating role of construal level in explaining consumers’ purchase intention and the moderating role of message quality. Specifically, the effects found for study 1 appeared to be more pronounced for subjects exposed to the collectivistic appeal. Theoretical and managerial implications were discussed for researchers and practitioners. © 2021 Advertising Association. | Kim, Hyuksoo; Cheong, Yunjae; Kim, Kihan | School of Business Administration, College of Economics and Business Administration, Kyungpook National University, Daegu, South Korea; Division of Media Communication, Hankuk University of Foreign Studies, Seoul, South Korea; Department of Physical Education, Sport Management, Seoul National University, Seoul, South Korea | 57110953000; 28767587800; 35751379100 | iumyum@knu.ac.kr; | International Journal of Advertising | INT J ADVERT | 0265-0487 | 1759-3948 | SSCI | BUSINESS;COMMUNICATION | 2021 | 5.888 | 7.9 | 0.48 | 2025-07-30 | 5 | collectivistic; Construal level; guilt; individualistic; message quality; shame; time restriction | English | Article in press | 2021 | 10.1080/02650487.2021.2022290 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | A Hubble Space Telescope Imaging Survey of Low-redshift Swift-BAT Active Galaxies* | We present initial results from a Hubble Space Telescope snapshot imaging survey of the host galaxies of Swift-BAT active galactic nuclei (AGN) at z < 0.1. The hard X-ray selection makes this sample relatively unbiased in terms of obscuration, compared to optical AGN selection methods. The high-resolution images of 154 target AGN enable us to investigate the detailed photometric structure of the host galaxies, such as the Hubble type and merging features. We find 48% and 44% of the sample to be hosted by early-type and late-type galaxies, respectively. The host galaxies of the remaining 8% of the sample are classified as peculiar galaxies because they are heavily disturbed. Only a minor fraction of host galaxies (18%-25%) exhibit merging features (e.g., tidal tails, shells, or major disturbance). The merging fraction increases strongly as a function of bolometric AGN luminosity, revealing that merging plays an important role in triggering luminous AGN in this sample. However, the merging fraction is weakly correlated with the Eddington ratio, suggesting that merging does not necessarily lead to an enhanced Eddington ratio. Type 1 and Type 2 AGN are almost indistinguishable in terms of their Hubble type distribution and merging fraction. However, the merging fraction of Type 2 AGN peaks at a lower bolometric luminosity compared with those of Type 1 AGN. This result may imply that the triggering mechanism and evolutionary stages of Type 1 and Type 2 AGN are not identical. | Kim, Minjin; Barth, Aaron J.; Ho, Luis C.; Son, Suyeon | Kyungpook Natl Univ, Dept Astron & Atmospher Sci, Daegu 702701, South Korea; Univ Calif Irvine, Dept Phys & Astron, 4129 Frederick Reines Hall, Irvine, CA 92697 USA; Peking Univ, Kavli Inst Astron & Astrophys, Beijing 100871, Peoples R China; Peking Univ, Sch Phys, Dept Astron, Beijing 100871, Peoples R China | ; Kim, Minjin/AAU-9910-2020 | 56898213300; 36088948300; 57225302746; 57226328130 | mkim.astro@gmail.com;lho.pku@gmail.com; | ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES | ASTROPHYS J SUPPL S | 0067-0049 | 1538-4365 | 256 | 2 | SCIE | ASTRONOMY & ASTROPHYSICS | 2021 | 9.2 | 8.0 | 1.26 | 2025-07-30 | 22 | 20 | SUPERMASSIVE BLACK-HOLES; LINE SEYFERT-1 GALAXIES; AGN HOST GALAXIES; SIMILAR-TO 0.6; GALACTIC NUCLEI; MERGERS; QUASARS; MASS; EMISSION; LUMINOSITY | figure set; machine-readable tables | English | 2021 | 2021-10 | 10.3847/1538-4365/ac133e | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
