| ○ | ○ | Article | Learning Translation-Based Knowledge Graph Embeddings by N-Pair Translation Loss | Translation-based knowledge graph embeddings learn vector representations of entities and relations by treating relations as translation operators over the entities in an embedding space. Since the translation is represented through a score function, translation-based embeddings are trained in general by minimizing a margin-based ranking loss, which assigns a low score to positive triples and a high score to negative triples. However, this type of embedding suffers from slow convergence and poor local optima because the loss adopts only one pair of a positive and a negative triple at a single update of learning parameters. Therefore, this paper proposes the N-pair translation loss that considers multiple negative triples at one update. The N-pair translation loss employs multiple negative triples as well as one positive triple and allows the positive triple to be compared against the multiple negative triples at each parameter update. As a result, it becomes possible to obtain better vector representations rapidly. The experimental results on link prediction prove that the proposed loss helps to quickly converge toward good optima at the early stage of training. | Song, Hyun-Je; Kim, A-Yeong; Park, Seong-Bae | Jeonbuk Natl Univ, Dept Informat Technol, Jeonju 54896, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Kyung Hee Univ, Dept Comp Sci & Engn, Yongin 17104, South Korea | 35175084000; 42661508900; 7501838676 | hyunje.song@jbnu.ac.kr;aykim@sejong.knu.ac.kr;sbpark71@khu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.54 | 2025-06-25 | 6 | 10 | knowledge graph embeddings; translation-based knowledge graph embeddings; N-pair translation loss; negative sampling; multiple negative triples | Knowledge graph embeddings; Multiple negative triples; N-pair translation loss; Negative sampling; Translation-based knowledge graph embeddings | English | 2020 | 2020-06 | 10.3390/app10113964 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | License Plate Image Generation using Generative Adversarial Networks for End-To-End License Plate Character Recognition from a Small Set of Real Images | License Plate Character Recognition (LPCR) is a technology for reading vehicle registration plates using optical character recognition from images and videos, and it has a long history due to its usefulness. While LPCR has been significantly improved with the advance of deep learning, training deep networks for LPCR module requires a large number of license plate (LP) images and their annotations. Unlike other public datasets of vehicle information, each LP has a unique combination of characters and numbers depending on the country or the region. Therefore, collecting a sufficient number of LP images is extremely difficult for normal research. In this paper, we propose LP-GAN, an LP image generation method, by applying an ensemble of generative adversarial networks (GAN), and we also propose a modified lightweight YOLOv2 model for an efficient end-to-end LPCR module. With only 159 real LP images available online, thousands of synthetic LP images were generated by using LP-GAN. The generated images not only looked similar to real ones, but they were also shown to be effective for training the LPCR module. As a result of performance tests with 22,117 real LP images, the LPCR module trained with only the generated synthetic dataset achieved 98.72% overall accuracy, which is comparable to that of training with a real LP image dataset. In addition, we improved the processing speed of LPCR about 1.7 times faster than that of the original YOLOv2 model by using the proposed lightweight model. | Han, Byung-Gil; Lee, Jong Taek; Lim, Kil-Taek; Choi, Doo-Hyun | Elect & Telecommun Res Inst, Daegu 42994, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 55985294200; 24341317500; 7403175725; 7401642881 | dhc@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.4 | 2025-06-25 | 19 | 26 | license plate image generation; ensemble data; segmentation-free; end-to-end recognition; GAN; ALPR | SEGMENTATION | ALPR; End-to-end recognition; Ensemble data; GAN; License plate image generation; Segmentation-free | English | 2020 | 2020-02 | 10.3390/app10082780 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Line-Detection Based on the Sum of Gradient Angle Differences | This paper presents a method to detect line pixels based on the sum of gradient angle differences (SGAD). The gradient angle differences are calculated by comparing the four pairs of gradients arising from eight neighboring pixels. In addition, a method to classify line pixels into ridges and valleys is proposed. Furthermore, a simple line model is defined for simulation experiments. Experiments are conducted with simulation images generated using the simple line model for three line-detection methods: second-derivatives (SD)-based method, extremity-count (EC)-based method, and proposed method. The results of the simulation experiments show that the proposed method produces more accurate line-detection results than the other methods in terms of the root mean square error when the line width is relatively large. In addition, the experiments conducted with natural images show that the SD- and EC-based methods suffer from bifurcation, fragmentation, and missing pixels. By contrast, for the original and the noise-contaminated versions of the natural images, the proposed SGAD-based line-detection method is affected by such problems to a considerably smaller extent than the other two methods. | Seo, Suyoung | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | Seo, Suyoung/AAB-8465-2020 | 35198914000 | syseo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.39 | 2025-06-25 | 6 | 5 | line-detection; gradient; angle difference | BLUR IDENTIFICATION; RIDGE DETECTION; EXTRACTION; IMAGE; PARAMETERS; VALLEYS | Angle difference; Gradient; Line-detection | English | 2020 | 2020-01 | 10.3390/app10010254 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Machine Learning-Based Code Auto-Completion Implementation for Firmware Developers | With the advent of artificial intelligence, the research paradigm in natural language processing has been transitioned from statistical methods to machine learning-based approaches. One application is to develop a deep learning-based language model that helps software engineers write code faster. Although there have already been many attempts to develop code auto-completion functionality from different research groups, a need to establish an in-house code has been identified for the following reasons: (1) a security-sensitive company (e.g., Samsung Electronics) may not want to utilize commercial tools given that there is a risk of leaked source codes and (2) commercial tools may not be applicable to the specific domain (e.g., SSD firmware development) especially if one needs to predict unique code patterns and style. This research proposes a hybrid approach that harnesses the synergy between machine learning techniques and advanced design methods aiming to develop a code auto-completion framework that helps firmware developers write code in a more efficient manner. The sensitivity analysis results show that the deterministic design results in reducing prediction accuracy as it generates output in some unexpected ways, while the probabilistic design provides a list of reasonable next code elements in which one could select it manually to increase prediction accuracy. | Kim, Junghyun; Lee, Kyuman; Choi, Sanghyun | Georgia Inst Technol, Sch Computat Sci & Engn, Atlanta, GA 30332 USA; Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu 41566, South Korea; Samsung Elect, Memory SW Dev Team, Hwasung 18448, South Korea | lee, kyuman/AAM-6979-2020 | 57197770173; 57193932345; 57220046311 | andy.kim@gatech.edu;klee400@knu.ac.kr;sh518.choi@samsung.com; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 23 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.23 | 2025-06-25 | 3 | 4 | machine learning; code auto-completion; GPT-2 model; advanced design methods | Advanced design methods; Code auto-completion; GPT-2 model; Machine learning | English | 2020 | 2020-12 | 10.3390/app10238520 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Overlap Avoidance of Mobility Models for Multi-UAVs Reconnaissance | As avionics technologies have advanced, it is possible to perform many aerial applications which demand cooperative work with multiple Unmanned Aerial Vehicles (UAVs). Since one of the basic applications is reconnaissance, we focus on efficient cooperative reconnaissance. While random mobility models are useful for multi-UAVs reconnaissance, they suffer from overlapped reconnaissance problem that two or more UAVs reconnoiter a region at the same time. The overlapped reconnaissance also leads to imbalanced reconnaissance in which an area scanned by one UAV may be re-visited soon by the other UAV. Thus, we provide overlap avoidance schemes for the existing reconnaissance mobility models and enhance their performance. Throughout the simulations, we evaluate the effect of applying overlap avoidance in the existing models. The simulation results show that overlapped area is reduced by up to 20 times and 90%-coverage reaching time is improved by up to 19%. | Jo, Yong-il; Lee, Seonah; Kim, Kyong Hoon | Gyeongsang Natl Univ, Dept Informat, Jinju 52828, Gyeongsangnamdo, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daehak Ro, Daegu 41566, South Korea | Kim, Honghyok/LDF-5356-2024 | 57211049631; 25822639700; 15065463500 | crues@gnu.ac.kr;saleese@gnu.ac.kr;kyong.kim@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.54 | 2025-06-25 | 8 | 8 | UAV; mobility model; reconnaissance; overlap avoidance | Mobility model; Overlap avoidance; Reconnaissance; UAV | English | 2020 | 2020-06 | 10.3390/app10114051 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Performance Analysis of the Supercritical Carbon Dioxide Re-compression Brayton Cycle | This paper presents performance analysis results on supercritical carbon dioxide (sCO(2)) re-compression Brayton cycle. Monthly exergy destruction analysis was conducted to find the effects of different ambient and water temperatures on the performance of the system. The results reveal that the gas cooler is the major source of exergy destruction in the system. The total exergy destruction has the lowest value of 390.1 kW when the compressor inlet temperature is near the critical point (at 35 degrees C) and the compressor outlet pressure is comparatively low (24 MPa). The optimum mass fraction (x) and efficiency of the cycle increase with turbine inlet temperature. The highest efficiency of 49% is obtained at the mass fraction of x = 0.74 and turbine inlet temperature of 700 degrees C. For predicting the cost of the system, the total heat transfer area coefficient (UA(Total)) and size parameter (SP) are used. The UA(Total) value has the maximum for the split mass fraction of 0.74 corresponding to the maximum value of thermal efficiency. The SP value for the turbine is 0.212 dm at the turbine inlet temperature of 700 degrees C and it increases with increasing turbine inlet temperature. However the SP values of the main compressor and re-compressor increase with increasing compressor inlet temperature. | Salim, Mohammad Saad; Saeed, Muhammad; Kim, Man Hoe | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, IEDT, Daegu 41566, South Korea; Khalifa Univ Sci & Technol, Mech Engn Dept, SAN Campus,POB 2533, Abu Dhabi, U Arab Emirates | ; Saeed, Muhammad/R-4401-2019 | 57205432225; 56513270400; 55686310000 | msaadsalim@hotmail.com;saeed.aarib@gmail.com;kimmh@asme.org; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.25 | 2025-06-25 | 20 | 22 | re-compression Brayton cycle; carbon dioxide; supercritical; thermodynamic; exergy; cycle simulation; design point analysis | ORGANIC RANKINE-CYCLE; PARAMETRIC OPTIMIZATION; POWER-GENERATION; HEAT; SELECTION; ORC | Carbon dioxide; Cycle simulation; Design point analysis; Exergy; Re-compression Brayton cycle; Supercritical; Thermodynamic | English | 2020 | 2020-02 | 10.3390/app10031129 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Preparation of an Oxygen-Releasing Capsule for Large-Sized Tissue Regeneration | Sufficient oxygenation for prevention of cellular damage remains a critical barrier to successful tissue engineering, especially in the construction of a large-sized tissue despite numerous attempts to resolve this issue in recent years. There have been a number of hypothetical solutions to this problem, including the use of artificial oxygen carriers, induction of vascularization, and fabrication of oxygen-generating biomaterials. All of these efforts have improved the efficiency of oxygen supply, but none have been able to support the large tissue mass required for clinical application. Necrosis, which often occurs during hypoxic stress, is one of the most significant limitations in large-sized tissue regeneration. In this study, we developed an oxygen producing capsule using hydrogen peroxide (H2O2), PLGA (poly (lactic-co-glycolic acid) and alginate, and also evaluated the capsule as a model of a large-sized tissue. Firstly, H2O2 was microencapsulated by PLGA, and subsequently the H2O2-PLGA microspheres were embedded into a catalase-immobilized alginate capsule of 5.0 mm in diameter. The alginate capsules of a fairly large size were characterized for their oxygenation capability to cells embedded such as human umbilical vein endothelial cells (HUVECs) by HIF-1 alpha and VEGF expression. The results of this study confirmed that in the oxygen-releasing capsule composed of H2O2 polymeric microspheres and catalase-bound alginate, HUVEC cells successfully survived in the hypoxic state. These results demonstrated that our oxygen producing system containing H2O2-PLGA microspheres could be a useful oxygenating biomaterial for engineering large-sized tissue. | Choi, Jeongyeon; Chun, So Young; Kwon, Tae Gyun; Lim, Jeong Ok | Korea Inst Ind Technol KITECH, Safety Syst R&D Grp, Daegyeong Reg Div, Daegu 42994, South Korea; Kyungpook Natl Univ Hosp, Biomed Res Inst, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu 41566, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Joint Inst Regenerat Med, Biomed Res Inst,Sch Med, Daegu 41944, South Korea | 56126683400; 8688166900; 15073765400; 7403454245 | jychoi77@kitech.re.kr;soyachun@gmail.com;tgkwon@knu.ac.kr;jolim@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 23 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.08 | 2025-06-25 | 2 | 1 | oxygen diffusion; drug delivery system; control release; encapsulation; EDC; NHS | Control release; Drug delivery system; EDC/NHS; Encapsulation; Oxygen diffusion | English | 2020 | 2020-12 | 10.3390/app10238399 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Privacy-Preserving Lightweight Authentication Protocol for Demand Response Management in Smart Grid Environment | With the development in wireless communication and low-power device, users can receive various useful services such as electric vehicle (EV) charging, smart building, and smart home services at anytime and anywhere in smart grid (SG) environments. The SG devices send demand of electricity to the remote control center and utility center (UC) to use energy services, and UCs handle it for distributing electricity efficiently. However, in SG environments, the transmitted messages are vulnerable to various attacks because information related to electricity is transmitted over an insecure channel. Thus, secure authentication and key agreement are essential to provide secure energy services for legitimate users. In 2019, Kumar et al. presented a secure authentication protocol for demand response management in the SG system. However, we demonstrate that their protocol is insecure against masquerade, the SG device stolen, and session key disclosure attacks and does not ensure secure mutual authentication. Thus, we propose a privacy-preserving lightweight authentication protocol for demand response management in the SG environments to address the security shortcomings of Kumar et al.'s protocol. The proposed protocol withstands various attacks and ensures secure mutual authentication and anonymity. We also evaluated the security features of the proposed scheme using informal security analysis and proved the session key security of proposed scheme using the ROR model. Furthermore, we showed that the proposed protocol achieves secure mutual authentication between the SG devices and the UC using Burrows-Abadi-Needham (BAN) logic analysis. We also demonstrated that our authentication protocol prevents man-in-the-middle and replay attacks utilizing AVISPA simulation tool and compared the performance analysis with other existing protocols. Therefore, the proposed scheme provides superior safety and efficiency other than existing related protocols and can be suitable for practical SG environments. | Yu, SungJin; Park, KiSung; Lee, JoonYoung; Park, YoungHo; Park, YoHan; Lee, SangWoo; Chung, BoHeung | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Daejeon 34129, South Korea; Keimyung Univ, Sch Comp Engn, Daegu 42601, South Korea | Lee, JoonYoung/AAM-9838-2021; Park, Kisung/KIG-3849-2024 | 57203974524; 57194833768; 57203970123; 56962990300; 55660095600; 57201864359; 57214639923 | darkskiln@knu.ac.kr;ks.park@etri.re.kr;harry250@naver.com;parkyh@knu.ac.kr;yhpark@kmu.ac.kr;ttomlee@etri.re.kr;bhjung@etri.re.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.87 | 2025-06-25 | 33 | 38 | smart grid; authentication; informal security analysis; BAN logic; ROR model; AVISPA | KEY MANAGEMENT; SCHEME; SECURE; EXCHANGE | AVISPA; BAN logic; Informal security analysis; ROR model; Smart grid authentication | English | 2020 | 2020-03 | 10.3390/app10051758 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Real-Time State of Charge Estimation for Each Cell of Lithium Battery Pack Using Neural Networks | Featured Application Authors are encouraged to provide a concise description of the specific application or a potential application of the work. This section is not mandatory. With the emergence of problems on environmental pollutions, lithium batteries have attracted considerable attention as an efficient and nature-friendly alternative energy storage device owing to their advantages, such as high power density, low self-discharge rate, and long life cycle. They are widely used in numerous applications, from everyday items, such as smartphones, wireless vacuum cleaners, and wireless power tools, to transportation means, such as electric vehicles and bicycles. In this paper, the state of charge (SOC) of each cell of the lithium battery pack was estimated in real time using two types of neural networks: Multi-layer Neural Network (MNN) and Long Short-Term Memory (LSTM). To determine the difference in the SOC estimation performance under various conditions, the input values were compared using 2, 6, and 8 input values, and the difference according to the use of temperature variable data was compared, and finally, the MNN and LSTM. The differences were compared. Real-time SOC was estimated using the method with the lowest error rate. | Park, JaeHyung; Lee, JongHyun; Kim, SiJin; Lee, InSoo | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | 57220131740; 57201265019; 57835319600; 54979862300 | hyng809@naver.com;whdugs8428@knu.ac.kr;ninja2897@naver.com;insoolee@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 23 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.32 | 2025-06-25 | 23 | 25 | lithium battery Pack; State of Charge; Multi-Layer Neural Network; Long Short-Term Memory; real-time | Lithium battery Pack; Long Short-Term Memory; Multi-Layer Neural Network; Real-time; State of Charge | English | 2020 | 2020-12 | 10.3390/app10238644 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Reducing Dynamic Power Consumption in Mixed-Critical Real-Time Systems | In this paper, we study energy minimization consumption of a mixed criticality real-time system on uni-core. Our focus is on a new scheduling scheme to decrease the frequency level in order to conserve power. Since many systems are equipped with dynamic power and frequency level memory, power can be saved by decreasing the system frequency. In this paper, we provide new dynamic energy minimization consumption in mixed-criticality real-time systems. Recent research has been done on low-criticality mode for power reduction. Thus, the proposed scheme can reduce the energy both in high-criticality and low-criticality modes. The effectiveness of our proposed scheme in energy reduction is clearly shown through simulations results. | Ali, Ijaz; Jo, Yong-Il; Lee, Seonah; Lee, Wan Yeon; Kim, Kyong Hoon | Gyeongsang Natl Univ, Dept Informat, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept AI Convergence Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Aerosp & Software Engn, Jinju 52828, South Korea; DongdukWomens Univ, Dept Comp Sci, Seoul 02748, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | Kim, Honghyok/LDF-5356-2024; Ali, Ijaz/LLL-1959-2024 | 57210456163; 57211049631; 25822639700; 14024347300; 15065463500 | ijazali1984@gnu.ac.kr;crues@gnu.ac.kr;saleese@gnu.ac.kr;wanlee@dongduk.ac.kr;kyong.kim@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.54 | 2025-06-25 | 7 | 10 | mixed-criticality; power-aware; real-time scheduling; DVFS | ALGORITHM | DVFS; Mixed-criticality; Power-aware; Real-time scheduling | English | 2020 | 2020-10 | 10.3390/app10207256 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Resonant Transmission Through a Single Subwavelength Slit for Varied Metallic Permittivities and Its Modal Orthogonality | This article investigates resonant transmission phenomena through a single metallic subwavelength slit when the permittivity of a real metal varies. The single metallic slit is utilized as a metal-insulator-metal waveguide, and a mode-matching technique is employed to obtain the transmitted power. The periodic resonant transmission phenomena (in terms of the metallic plate thickness) are solved, and the resonances can be understood by their guide wavelengths. Even when the permittivity of the real metal includes imaginary parts (i.e., metal with loss), the resonant transmittances are obtained. However, the peaks of the transmittances decrease, as the plate thickness increases. The orthogonal relationship of an incomplete orthogonal set is maintained despite metallic loss (given a relatively small amount of loss), due to the complex permittivity of the real metal. | Park, Jong-Eon; Choo, Hosung; Cho, Young-Ki | Hongik Univ, Metamat Elect Device Res Ctr, Seoul 04066, South Korea; Hongik Univ, Sch Elect & Elect Engn, Seoul 04066, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | Choo, Hosung/AAG-3411-2020 | 24483843100; 14009489300; 7404469777 | jongeon.park@gmail.com;hschoo@hongik.ac.kr;ykcho@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0 | 2025-06-25 | 0 | 0 | transmission cross-section; metal-insulator-metal waveguide; mode-matching technique | ELECTROMAGNETIC TRANSMISSION | Metal-insulator-metal waveguide; Mode-matching technique; Transmission cross-section | English | 2020 | 2020-01 | 10.3390/app10020660 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Secure Key Agreement and Authentication Protocol for Message Confirmation in Vehicular Cloud Computing | With the development of vehicular ad-hoc networks (VANETs) and Internet of vehicles (IoVs), a large amount of useful information is generated for vehicle drivers and traffic management systems. The amount of vehicle and traffic information is as large as the number of vehicles and it is enormous when compared to vehicle calculation and storage performance. To resolve this problem, VANET uses a combined cloud computing technology, called vehicular cloud computing (VCC), which controls vehicle-related data, and helps vehicle drivers directly or indirectly. However, VANETs remain vulnerable to attacks such as tracking, masquerade and man-in-the-middle attacks because VANETs communicate via open networks. To overcome these issues, many researchers have proposed secure authentication protocols for message confirmation with vehicular cloud computing. However, many researchers have pointed out that some proposed protocols use ideal tamper-proof devices (TPDs). They demonstrated that realistic TPDs cannot prevent adversaries attack. Limbasiya et al. presented a message confirmation scheme for vehicular cloud computing using a realistic TPD in order to prevent these problems. However, their proposed scheme still has security weaknesses over a TPD and does not guarantee mutual authentication. This paper proposes a secure key agreement and authentication protocol to address the security weaknesses inherent in the protocol of Limbasiya et al. The suggested protocol withstands malicious attacks and ensures secure mutual authentication for privacy-preserving. We prove that the proposed protocol can provide session key security using Real-Or-Random (ROR) model. We also employed Automated Validation of Internet Security Protocols and Applications (AVISPA) simulation tool to show that the proposed protocol is able to defeat replay and man-in-the-middle attacks. Furthermore, we established that the proposed protocol can resist other malicious attacks by conducting the informal security analysis. We proved that our proposed protocol is lightweight and suitable for VCC environments. | Lee, JoonYoung; Yu, SungJin; Kim, MyeongHyun; Park, YoungHo; Lee, SangWoo; Chung, BoHeung | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Elect & Telecommun Res Inst, Daejeon 34129, South Korea | Lee, JoonYoung/AAM-9838-2021 | 57203970123; 57203974524; 57210278739; 56962990300; 57201864359; 57214639923 | harry250@knu.ac.kr;darkskiln@knu.ac.kr;kimmyeong123@knu.ac.kr;parkyh@knu.ac.kr;ttomlee@etri.re.kr;bhjung@etri.re.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.78 | 2025-06-25 | 12 | 15 | VANET; vehicular cloud computing; message confirmation; cryptanalysis; mutual authentication; AVISPA; ROR model | LIGHTWEIGHT AUTHENTICATION; MANAGEMENT PROTOCOL; SCHEME; INTERNET; VERIFICATION; DESIGN | AVISPA; Cryptanalysis; Message confirmation; Mutual authentication; ROR model; VANET; Vehicular cloud computing | English | 2020 | 2020-09 | 10.3390/app10186268 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Simulation of Debris-Flow Runout Near a Construction Site in Korea | This study analyzed landslide susceptibility and numerically simulated the runout distance of debris flows near a construction site in Korea. Landslide susceptibility was based on a landslide prediction map of the study area. In the prediction map, 3.5% of the area had a 70-90% landslide probability, while 0.79% had over 90% probability. Based on the landslide susceptibility analysis, debris flows in four watersheds were simulated to assess possible damage to the construction site. According to the simulations, debris flow in Watershed C approaches to within 9.6 m of the site. Therefore, the construction site could be impacted by debris flow in Watershed C. Although the simulated flows in Watersheds A and D do not directly influence the construction site, they could damage the nearby road and other facilities. The simulations also show that debris runout distance is strongly influenced by the volume of debris in the on-slope source area and by the slope angles along the debris-flow path. | Chae, Byung-Gon; Wu, Ying-Hsin; Liu, Ko-Fei; Choi, Junghae; Park, Hyuck-Jin | Korea Inst Geosci & Mineral Resources KIGAM, Policy & Planning Div, Daejeon 34132, South Korea; Kyoto Univ, Disaster Prevent Res Inst, Kyoto 6110011, Japan; Natl Taiwan Univ, Dept Civil Engn, Taipei 10617, Taiwan; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Sejong Univ, Dept Energy Resources & Geosyst Engn, Seoul 05006, South Korea | Wu, Ying-Hsin/G-5628-2012; Park, Hyuck-Jin/AAY-6787-2021 | 35782715300; 56699027700; 7404200494; 55839820300; 9334620800 | bgchae@kigam.re.kr;yhwu@hmd.dpri.kyoto-u.ac.jp;kfliu@ntu.edu.tw;choi.jh@knu.ac.kr;hjpark@sejong.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 17 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.16 | 2025-06-25 | 6 | 6 | landslide susceptibility; simulation of debris flow; runout distance; volume of debris; slope angle | LANDSLIDE SUSCEPTIBILITY; LOGISTIC-REGRESSION; SHALLOW LANDSLIDES; SLOPE STABILITY; HAZARD; PREDICTION; PARAMETERS; MODELS; TRAVEL; ANGLE | Landslide susceptibility; Runout distance; Simulation of debris flow; Slope angle; Volume of debris | English | 2020 | 2020-09 | 10.3390/app10176079 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Simultaneous Enhancement of Electrical and Optical Properties of Transparent Conducting RuO2Nanosheet films by Facile Ultraviolet-Ozone Irradiation | The enhancement of electrical and optical properties in transparent conducting electrodes has attracted significant interest for their application in flexible electronic devices. Herein, a method for the fabrication of transparent conducting films is proposed. In this approach, RuO(2)nanosheets are synthesized by a simple chemical exfoliation method and deposited as conducting films by repeated Langmuir-Blodgett coating. For enhancing the electrical and optical properties of the films, ultraviolet-ozone irradiation is applied between the repeated coatings for the removal of residual organic materials from the chemically exfoliated nanosheets. We observe that by applying ultraviolet-ozone irradiation for 30 min, the sheet resistance of the films decreases by 10% and the optical transmittance is simultaneously enhanced. Facile ultraviolet-ozone irradiation is shown to be an effective and industrially friendly method for enhancing the electrical and optical properties of oxide nanosheets for their application as transparent conduction electrodes. | Roh, Jong Wook; Shin, Weon Ho; Kim, Hyun-Sik; Kim, Se Yun; Kim, Sang-il | Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, Gyeongsangbuk Do 37224, South Korea; Kwangwoon Univ, Dept Elect Mat Engn, Seoul 01897, South Korea; Hongik Univ, Dept Mat Sci & Engn, Seoul 04066, South Korea; Samsung Elect, Suwon 16678, South Korea; Univ Seoul, Dept Mat Sci & Engn, Seoul 02504, South Korea | ; Kim, Sung/A-4747-2013; Kim, Seung/N-5248-2019; Shin, Weon/AAH-4031-2020 | 25638796100; 57204152565; 56526077500; 57203210313; 36171889900 | jw.roh@knu.ac.kr;weonho@kw.ac.kr;hyunsik.kim@hongik.ac.kr;ksyvip@gmail.com;sang1.kim@uos.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 12 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.23 | 2025-06-25 | 3 | 3 | nanosheets; RuO2; transparent electrodes; ultraviolet-ozone irradiation; sheet resistance; optical transmittance | RUO2 NANOPARTICLES; EXFOLIATION; NANOSHEETS; GRAPHITE | Nanosheets; Optical transmittance; RuO<sub>2</sub>; Sheet resistance; Transparent electrodes; Ultraviolet-ozone irradiation | English | 2020 | 2020-06 | 10.3390/app10124127 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Strategic Use of CAD-CAM Interim Restoration for the Recovery of the Vertical Dimension of Occlusion in the Posterior Partially Edentulous Jaw | Occlusal contact loss occasionally occurs following the placement of implant-supported fixed dental prostheses in the posterior region. This complication is caused by the change in the vertical dimension of occlusion after the recovery of mastication. The change is probably related to the prosthesis sinking phenomenon and previous mandibular dislocation. The use of interim prostheses could help re-establish the vertical dimension of occlusion. The definitive prostheses can then be accurately fabricated using digital techniques in the newly established vertical dimension. In this case report, we introduce a protocol incorporating a computer-aided design and computer-aided manufacturing (CAD-CAM) interim prosthesis and digital techniques to minimize the occurrence of unexpected initial occlusal changes in the prosthetic treatment of implant-supported prostheses in the posterior region. | Mai, Hai Yen; Seo, Jae-Min; Jung, Jae-Kwang; Lee, Du-Hyeong | Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea; Jeonbuk Natl Univ, Sch Dent, Inst Oral Biosci, Dept Prosthodont, Jeonju 54896, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Med, IHBR, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Translat Res Dent, Daegu 41940, South Korea | 57217872800; 55838533000; 55970994400; 35770948000 | maihaiyen@knu.ac.kr;jmseo@jbnu.ac.kr;widenmy@knu.ac.kr;deweylee@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.16 | 2025-06-25 | 2 | 2 | occlusal contact loss; implant; fixed dental prosthesis; interim; CAD-CAM; vertical dimension | IMPLANT; DISPLACEMENT; CROWNS; ZIRCONIA; CAD/CAM | CAD-CAM; Fixed dental prosthesis; Implant; Interim; Occlusal contact loss; Vertical dimension | English | 2020 | 2020-11 | 10.3390/app10217735 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
