| ○ | ○ | Article | Full-Parallax Multiview Generation with High-Speed Wide-Angle Dual-Axis Scanning Optics | Three-dimensional displays are receiving considerable attention owing to their ability to deliver realistic content. Particularly, a multiview display with temporal multiplexing offers advantages in terms of fewer restrictions for optical alignment and flexibility in forming view density. However, most of studies realize horizontal parallax-only multiview display. In a horizontal parallax-only multiview display the content is distorted in the vertical direction as the observer changes the viewing distance. It is helpful to understand this phenomenon using the Wigner distribution function (WDF). In this study, we divided the viewing zone (VZ) into the sub-viewing zone and integrated viewing zone according to the number of views of the observer. Specifically, the changes in the contents are experimentally evaluated at different viewing distances to validate our expectation. For the experiment, we implemented a full-parallax multiview display with spherical symmetry and designed a high-speed wide-angle dual-axis scanner. This scanner comprises two single-axis scanners connected by high numerical-aperture scanning optics. The proposed system and WDF analysis of VZ will be helpful to evaluate the characteristics of the multiview system. | Heo, Daerak; Lim, Sungjin; Lee, Gunhee; Choi, Geunseop; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57197871664; 56706721300; 57687190900; 57197870410; 10142501600 | qnehdauddnjf@knu.ac.kr;dlatjdwls0326@knu.ac.kr;gunhee7765@knu.ac.kr;geun4537@knu.ac.kr;jhahn@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.09 | 2025-06-25 | 1 | 1 | multiview display; three-dimensional display; temporal multiplexing; dual-axis scanner | LIGHT-FIELD; DISPLAY; SCREEN; ARRAY | dual-axis scanner; multiview display; temporal multiplexing; three-dimensional display | English | 2022 | 2022-05 | 10.3390/app12094615 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | GATA25, a novel regulator, accelerates the flowering time of Arabidopsis thaliana | Intrinsic and exogenous signals in conjunction precisely regulate the initiation of flowering. Both signals influence flowering time, which is an integral part of plant reproduction. The signals converge through different pathways, and their coordinated action leads to the onset of flowering. Genetic pathways related to the regulation of flowering time are well-known from research into the molecular genetics of Arabidopsis thaliana. Specifically, crucial components of the photoperiodic pathway and floral integrators play a critically significant role in flowering. In this study, we found that GATA25 is a novel transcription factor that accelerates flowering time under long days. GATA25 encodes C-X-2-C-X-20-C-X-2-C conserved cysteine residues of the zinc-finger domain and CCT domain which process photoperiodic flowering and regulate circadian rhythms. Flowering was accelerated by overexpression of GATA25 throughout the Arabidopsis thaliana. In contrast, GATA25 fused to SRDX (SUPERMAN repressive domain X)-motif plants showed delayed flowering. We also demonstrated that GATA25 induced the expression of floral integrator genes and photoperiodic pathway-related genes. Together, these results suggest that GATA25 might act to accelerate flowering time. | Kim, Kihwan; Lee, Jooeun; Kim, Byeonggyu; Shin, Juhyung; Kang, Tae-An; Kim, Won-Chan | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea | KIM, WON/AAJ-4506-2020 | 57210357476; 57897128100; 57222988339; 57222983867; 57652386200; 55492085000 | kwc@knu.ac.kr; | APPLIED BIOLOGICAL CHEMISTRY | APPL BIOL CHEM | 2468-0834 | 2468-0842 | 65 | 1 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2022 | 3.2 | 46.1 | 0.89 | 2025-06-25 | 11 | 11 | Arabidopsis thaliana; Flowering; Floral integrators; GATA25; Photoperiodic pathway | PLANT TRANSCRIPTION FACTORS; FLORAL INDUCTION; GENE-EXPRESSION; CIRCADIAN CLOCK; EAR MOTIF; LOCUS-T; CONSTANS; REPRESSION; HOMOLOG; PROTEIN | Arabidopsis thaliana; Floral integrators; Flowering; GATA25; Photoperiodic pathway | Amino acids; C (programming language); Cell proliferation; Molecular biology; Plants (botany); Arabidopsis thaliana; Coordinated actions; Floral integrator; Flowering; Flowering-time; GATA25; Genetic pathways; Integral part; Photoperiodic pathways; Plant reproduction; Transcription | English | 2022 | 2022-12 | 10.1186/s13765-022-00698-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Hierarchical Federated Learning for Edge-Aided Unmanned Aerial Vehicle Networks | Federated learning (FL) allows UAVs to collaboratively train a globally shared machine learning model while locally preserving their private data. Recently, the FL in edge-aided unmanned aerial vehicle (UAV) networks has drawn an upsurge of research interest due to a bursting increase in heterogeneous data acquired by UAVs and the need to build the global model with privacy; however, a critical issue is how to deal with the non-independent and identically distributed (non-i.i.d.) nature of heterogeneous data while ensuring the convergence of learning. To effectively address this challenging issue, this paper proposes a novel and high-performing FL scheme, namely, the hierarchical FL algorithm, for the edge-aided UAV network, which exploits the edge servers located in base stations as intermediate aggregators with employing commonly shared data. Experiment results demonstrate that the proposed hierarchical FL algorithm outperforms several baseline FL algorithms and exhibits better convergence behavior. | Tursunboev, Jamshid; Kang, Yong-Sung; Huh, Sung-Bum; Lim, Dong-Woo; Kang, Jae-Mo; Jung, Heechul | Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; WOOJIN Elect Machinery, 9,Igok Ro,1 Gil, Cheongju 28047, Chuncheongbuk D, South Korea; Elect & Telecommun Res Inst, Radio & Satellite Res Div, Daejeon 34129, South Korea | ; Jung, Heechul/HTL-7199-2023 | 57410135900; 57411013700; 57410136000; 55694295300; 56024930400; 55652175200 | tursunboevjamshid@gmail.com;yskang@wjis.co.kr;sbhur@wjis.co.kr;window0508@etri.re.kr;jmkang@knu.ac.kr;heechul@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 2.36 | 2025-06-25 | 26 | 29 | unmanned aerial vehicles; edge-aided networks; federated learning; hierarchical learning | COST | Edge-aided networks; Federated learning; Hierarchical learning; Unmanned aerial vehicles | English | 2022 | 2022-01 | 10.3390/app12020670 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Illuminant Adaptive Wideband Image Synthesis Using Separated Base-Detail Layer Fusion Maps | In this study, we present a wideband image synthesis technique for day and night object identification. To synthesize the visible and near-infrared images, a base component and a detailed component are first decomposed using a bilateral filter, and the detailed component is synthesized using a local variance map. In addition, considering the difference in the near-infrared image characteristics between daytime and nighttime, the base components are synthesized using a luminance saturation region map and depth and penetration map using a joint bilateral filter. The proposed method overcomes the partial over- or under-exposure caused by sunlight and infrared auxiliary light, which is experienced variously in wideband imaging, and improves the identification of objects in various indoor and outdoor images compared with that achieved by existing methods by emphasizing detailed components. | Park, Cheul-Woo; Kwon, Hyuk-Ju; Lee, Sung-Hak | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Deahakro, Daegu 702701, South Korea | 57927907500; 55169908300; 7601395661 | shak2@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.09 | 2025-06-25 | 1 | 1 | visible and near-infrared image fusion; joint bilateral filter; base-detail layer decomposition; IR switching image; color correction | PHOTOGRAPHY; FLASH | base-detail layer decomposition; color correction; IR switching image; joint bilateral filter; visible and near-infrared image fusion | English | 2022 | 2022-10 | 10.3390/app12199441 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Image Forensics Using Non-Reducing Convolutional Neural Network for Consecutive Dual Operators | Digital image forensics has become necessary as an emerging technology. Images can be adulterated effortlessly using image tools. The latest techniques are available to detect whether an image is adulterated by a particular operator. Most of the existing techniques are suitable for high resolution and manipulated images by a single operator. In a real scenario, multiple operators are applied to manipulate the image many times. In this paper, a robust moderate-sized convolutional neural network is proposed to identify manipulation operators and also the operator's sequence for two operators in particular. The proposed bottleneck approach is used to make the network deeper and reduce the computational cost. Only one pooling layer, called a global averaging pooling layer, is utilized to retain the maximum flow of information and to avoid the overfitting issue between the layers. The proposed network is also robust against low resolution and JPEG compressed images. Even though the detection of the operator is challenging due to the limited availability of statistical information in low resolution and JPEG compressed images, the proposed model can also detect an operator with different parameters and compression quality factors that are not considered in training. | Cho, Se-Hyun; Agarwal, Saurabh; Koh, Seok-Joo; Jung, Ki-Hyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Amity Univ, Sch Engn & Technol, Noida 201301, Uttar Pradesh, India; Kyungil Univ, Dept Cyber Secur, Gyongsan 38424, South Korea | ; Agarwal, Saurabh/AAC-5460-2020 | 57877582800; 57190606444; 8958394800; 32367673200 | csh831219@knu.ac.kr;sagarwal7@amity.edu;sjkoh@knu.ac.kr;kingjung@kiu.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 14 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.44 | 2025-06-25 | 4 | 5 | image forensics; image operator sequence; convolutional neural network; image manipulation; image forgery detection; deep learning technique | convolutional neural network; deep learning technique; image forensics; image forgery detection; image manipulation; image operator sequence | English | 2022 | 2022-07 | 10.3390/app12147152 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Review | Impact of Virtual Reality-Based Design Review System on User's Performance and Cognitive Behavior for Building Design Review Tasks | Virtual reality (VR) can potentially enhance various design and construction assessment intensive tasks, such as construction design and review. However, it may lead to cognitive overload, adversely affecting the participants' performance. It is critical to understand the effects of VR cognitive behavior for implementing VR technology in the construction industry. The principal objective of this study was to investigate the participants' cognitive load (CL), task performance (TP), and situational awareness (SA) in the VR environment for the evaluation of building design review tasks. Participants were asked to review the design task based on their memory knowledge and understanding in one of the three environments: paper-based, monitor-based, and immersive virtual environment. Participants' CL was measured using the National Aeronautics and Space Administration Task Load Index (NASA TLX), TP was evaluated on completion time and the number of errors correctly detected, and situational awareness (SA) was assessed using the Situational Awareness and Review Technique (SART). The statistical results show a high CL and better performance in the immersive virtual environment. These findings can contribute to a better understanding of cognitive process characteristics and capabilities for design review activities in the VR environment. | Umair, Muhammad; Sharafat, Abubakar; Lee, Dong-Eun; Seo, Jongwon | Natl Univ Sci & Technol NUST, Dept Construct Engn & Management, Risalpur 24080, Pakistan; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Hanyang Univ, Dept Civil & Environm Engn, Seoul 04763, South Korea | ; Sharafat, Abubakar/ITW-2048-2023; Umair, Muhammad/IQV-9289-2023 | 57206202199; 57204630290; 56605563300; 7401783784 | umairchughata@gmail.com;abubakarsharafat89@gmail.com;dolee@knu.ac.kr;jseo@hanyang.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 14 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 2.8 | 2025-06-25 | 26 | 32 | virtual reality; BIM; design review; cognitive load; task performance; immersive virtual reality | AUGMENTED REALITY; INSTRUCTIONAL-DESIGN; LOAD THEORY; CONSTRUCTION; ENVIRONMENT; BIM | BIM; cognitive load; design review; immersive virtual reality; task performance; virtual reality | English | 2022 | 2022-07 | 10.3390/app12147249 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Inhibition of TP53 Mutant Oral Cancer by Reactivating p53 | Background: Mutation of p53 is a frequent event, and mutant p53 exhibits low levels of acetylation and phosphorylation. This study aimed to investigate the effect of the histone deacetylase (HDAC) inhibitor, 4-hexylresorcinol (4HR), on the acetylation and phosphorylation of mutant p53 carcinoma cells and its therapeutic effects in a xenograft model. Methods: To determine the effect of 4HR on the acetylation and phosphorylation of p53, western blot analysis was performed using YD-9 and YD-15 cells. p53 siRNA was used to examine whether 4HR acts in a p53-dependent or independent manner. This was evaluated using a xenograft model. Results: In in vitro experiments when the concentration of 4HR was increased, the expression levels of HDAC4, acetylated p53 (Ac-p53), and phosphorylated p53 (p-p53) increased. Transfection with TP53 siRNA successfully suppressed p53 protein and TP53 mRNA expression. When 4HR was administered to a xenograft model, the tumour expansion rate was suppressed compared with the control, and the mice exhibited a higher survival rate. Conclusions: Our findings reveal that 4HR is a potential agent that restores loss of function in mutant p53 cancer cells via acetylation and phosphorylation of p53 as well as inhibition of HDAC4. | Kang, Yei-Jin; Kim, Dae-Won; Che, Xiangguo; Choi, Je-Yong; Kim, Seong-Gon | Gangneung Wonju Natl Univ, Dept Oral & Maxillofacial Surg, Kangnung 25457, South Korea; Gangneung Wonju Natl Univ, Coll Dent, Dept Oral Biochem, Kangnung 28644, South Korea; Kyungpook Natl Univ, Sch Med, Korea Mouse Phenotyping Ctr, Dept Biochem & Cell Biol,Cell & Matrix Res Inst, Daegu 41944, South Korea | ; Kim, Seong-Gon/AAF-7553-2020; Choi, Je-Yong/AAR-7334-2021 | 57211458783; 56194913400; 54792660600; 7501391068; 27171913700 | kyj292@hanmail.net;kimdw@gwnu.ac.kr;xiangguo0622@naver.com;jechoi@knu.ac.kr;kimsg@gwnu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 12 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.26 | 2025-06-25 | 2 | 3 | 4-hexylresorcinol; p53; phosphorylation; acetylation | POSTTRANSLATIONAL MODIFICATIONS; 4-HEXYLRESORCINOL; PHOSPHORYLATION; APOPTOSIS; ACTIVATION; CISPLATIN | 4-hexylresorcinol; acetylation; p53; phosphorylation | English | 2022 | 2022-06 | 10.3390/app12125921 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Inhibitory Effect of Coumarins and Isocoumarins Isolated from the Stems and Branches of Acer mono Maxim. against Escherichia coli β-Glucuronidase | We isolated eight known secondary metabolites, including two isocoumarins and six coumarins, from the stems and branches of Acer mono Maxim. Their structures were confirmed using nuclear magnetic resonance spectroscopy and by comparing the data to published reports. The inhibitory effects of all compounds (1-8) on Escherichia coli beta-glucuronidase were evaluated for the first time using in vitro assays. 3-(3,4-Dihydroxyphenyl)-8-hydroxyisocoumarin (1) displayed an inhibitory effect against beta-glucuronidase (IC50 = 58.83 +/- 1.36 mu M). According to the findings of kinetic studies, compound 1 could function as a non-competitive inhibitor. Molecular docking indicated that compound 1 binds to the allosteric binding site of beta-glucuronidase, and the results corroborated those from kinetic studies. Furthermore, molecular dynamics simulations of compound 1 were performed to identify the behavioral and dynamic properties of the protein-ligand complex. Our results reveal that compound 1 could be a lead metabolite for designing new beta-glucuronidase inhibitors. | Phong, Nguyen Viet; Min, Byung Sun; Yang, Seo Young; Kim, Jeong Ah | Kyungpook Natl Univ, Coll Pharm, Vessel Organ Interact Res Ctr, VOICE MRC, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Pharm, BK21 FOUR Community Based Intelligent Novel Drug, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Daegu Catholic Univ, Coll Pharm, Drug Res & Dev Ctr, Gyongsan 38430, South Korea; Sangji Univ, Dept Pharmaceut Engn, Wonju 26339, South Korea | Nguyen, Viet Phong/AAQ-4207-2021 | 57205196739; 55663638200; 57215036954; 24722570900 | syyang@sangji.ac.kr;jkim6923@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.7 | 2025-06-25 | 8 | 8 | Acer mono Maxim; isocoumarins; beta-glucuronidase; non-competitive inhibitor; allosteric binding site; molecular dynamics | STILBENE GLYCOSIDES | Acer monoMaxim; allosteric binding site; isocoumarins; molecular dynamics; non-competitive inhibitor; β-glucuronidase | English | 2022 | 2022-10 | 10.3390/app122010685 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Isolation and Screening of Odor-Reducing Microbes from Swine Manure and Its Role in Reducing Ammonia Release in Combination with Surfactant Foam | Swine farming facilities have increased the production of malodorous gases, which negatively affects people. Hence, we developed a new feasible bio-foam technology wherein long-lasting surfactant foam, including bacteria, were sprayed on swine manure. The surfactant foam acted as a physical barrier, suppressing NH3 release, and the aqueous-phase bacteria formed after foam breaking infiltrated in manure and degraded NH3. In this study, we first isolated NH3-degrading bacteria from swine manure. A bacterial consortium was prepared using the effective NH3-degrading strains Saccharomyces cerevisiae NRRL Y-12632 (99.88%) (TP1), Lactococcus lactis subsp. hordniae NBRC100931(T) (99.93%) (TP3), and Lactobacillus argentoratensis DSM 16365(T) (100%) (TP5). The surfactant foam used in this study was a dry foam (foam quality 98.5-99.0% and foam density 0.025-0.026 g/cm(3)), with a foam expansion of 110-112 and high foamability. Large bubbles were generated with a bubble density of 1 bubble/cm(2) and a foam lamella thickness of 0.12 mm. In a lab-scale study, foam was sprayed onto NH3-contaminated soil or real swine manure, which reduced the NH3 emission from the source (soil/manure) almost completely (97-100%), but NH3 was re-emitted after foam breaking (5 h: open reactor, 7 h: closed reactor). After loading the bacteria on the foam, the initial NH3 odor suppression was similar to that of the foam alone. However, NH3 was effectively reduced by microbial degradation even after foam breaking. Complete odor degradation was observed after 3 days (72 h; 90-100% reduction) for the NH3-contaminated soil, and 97.7% NH3 in the swine manure was reduced in 24 h. Furthermore, the reagent cost for preparing stable foam was reasonable, indicating its possible field extension. | Bajagain, Rishikesh; Gautam, Prakash; Thi Tuyet Nhan Le; Dahal, Ram Hari; Kim, Jaisoo; Jeong, Seung-Woo | Kunsan Natl Univ, Dept Environm Engn, Gunsan 54150, South Korea; Kyonggi Univ, Dept Life Sci, Suwon 16227, South Korea; Kyungpook Natl Univ, Sch Med, Dept Microbiol, Daegu 41944, South Korea | ; Bajagain, Rishikesh/ABB-2253-2020; Gautam, Prakash/ABB-2270-2020; Jeong, Seung-Woo/M-5500-2019; Dahal, Ram Hari/H-8673-2016 | 57201025243; 57209535783; 57450599400; 57110097800; 8718834500; 7402425257 | rbajagain@gmail.com;prakash02gautam@gmail.com;nhanle@kyonggi.ac.kr;ramhari.dahal@knu.ac.kr;jkimtamu@kyonggi.ac.kr;swjeong@kunsan.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.96 | 2025-06-25 | 11 | 11 | malodor; surfactant foam; odor suppression; bio-degradation; feasibility; infiltration; surfactant; stability; surface tension; foam application; foam cover technology | EMISSIONS; REMOVAL; GAS; HEALTH; NH3; AIR; H2S | Bio-degradation; Feasibility; Foam application; Foam cover technology; Infiltration; Malodor; Odor suppression; Stability; Surface tension; Surfactant; Surfactant foam | English | 2022 | 2022-02 | 10.3390/app12041806 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Joint Semantic Understanding with a Multilevel Branch for Driving Perception | Visual perception is a critical task for autonomous driving. Understanding the driving environment in real time can assist a vehicle in driving safely. In this study, we proposed a multi-task learning framework for simultaneous traffic object detection, drivable area segmentation, and lane line segmentation in an efficient way. Our network encoder extracts features from an input image and three decoders at multilevel branches handle specific tasks. The decoders share the feature maps with more similar tasks for joint semantic understanding. Multiple loss functions are automatically weighted summed to learn multiple objectives simultaneously. We demonstrate the effectiveness of this framework on a BerkeleyDeepDrive100K (BDD100K) dataset. In the experiment, the proposed method outperforms the competing multi-task and single-task methods in terms of accuracy and maintains a real-time inference at more than 37 frames per second. | Lee, Dong-Gyu; Kim, Yoon-Ki | Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Cyber Univ Korea, Dept Future Convergence, Seoul 03051, South Korea | 57169003900; 57540045700 | dglee@knu.ac.kr;ykkim77@cuk.edu; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.79 | 2025-06-25 | 7 | 9 | joint semantic understanding; multi-level branch network; drivable area segmentation; lane line segmentation; traffic object detection; real-time inference; multi-task learning | Drivable area segmentation; Joint semantic understanding; Lane line segmentation; Multi-level branch network; Multi-task learning; Real-time inference; Traffic object detection | English | 2022 | 2022-03 | 10.3390/app12062877 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Late Fusion-Based Video Transformer for Facial Micro-Expression Recognition | In this article, we propose a novel model for facial micro-expression (FME) recognition. The proposed model basically comprises a transformer, which is recently used for computer vision and has never been used for FME recognition. A transformer requires a huge amount of data compared to a convolution neural network. Then, we use motion features, such as optical flow and late fusion to complement the lack of FME dataset. The proposed method was verified and evaluated using the SMIC and CASME II datasets.

| ○ | ○ | Article | Leakage Current Mitigation of Photovoltaic System Using Optimized Predictive Control for Improved Efficiency | This paper proposes an optimized predictive control strategy to mitigate the potential leakage current of grid-tied photovoltaic (PV) systems to improve the lifespans of PV modules. In this work, the PV system is controlled with an optimized predictive control algorithm that selects the switching voltage vectors intelligently to reduce the number of computational burdens. Thus, it improves the dynamic performance of the overall system. This is achieved through a specific cost function that minimizes the change in common-mode voltage generated by the parasitic capacitance of PV modules. The proposed controller does not require any additional modulation schemes. Normalization techniques and weighting factors are incorporated to obtain improved results. The steady state and dynamic performance of the proposed control scheme is validated in this work through simulations and a 600 W experimental laboratory prototype. | Routray, Abhinandan; Hur, Sung-Ho | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ROUTRAY, ABHINANDAN/IVU-9009-2023 | 57200499011; 36455858700 | abhinandan@knu.ac.kr;hur.s.h@ieee.org;shur@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.52 | 2025-06-25 | 4 | 6 | predictive control; leakage current; PV; optimization; MLI | INVERTERS; MODE | Leakage current; MLI; Optimization; Predictive control; PV | English | 2022 | 2022-01 | 10.3390/app12020643 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Learned Semantic Index Structure Using Knowledge Graph Embedding and Density-Based Spatial Clustering Techniques | Recently, a pragmatic approach toward achieving semantic search has made significant progress with knowledge graph embedding (KGE). Although many standards, methods, and technologies are applicable to the linked open data (LOD) cloud, there are still several ongoing problems in this area. As LOD are modeled as resource description framework (RDF) graphs, we cannot directly adopt existing solutions from database management or information retrieval systems. This study addresses the issue of efficient LOD annotation organization, retrieval, and evaluation. We propose a hybrid strategy between the index and distributed approaches based on KGE to increase join query performance. Using a learned semantic index structure for semantic search, we can efficiently discover interlinked data distributed across multiple resources. Because this approach rapidly prunes numerous false hits, the performance of join query processing is remarkably improved. The performance of the proposed index structure is compared with some existing methods on real RDF datasets. As a result, the proposed indexing method outperforms existing methods due to its ability to prune a lot of unnecessary data scanned during semantic searching. | Sun, Yuxiang; Chun, Seok-Ju; Lee, Yongju | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Seoul Natl Univ Educ, Dept Comp Educ, Seoul 06639, South Korea | 57202927837; 7202148268; 57207015176 | syx921120@gmail.com;chunsj@snue.ac.kr;yongju@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 13 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.52 | 2025-06-25 | 6 | 6 | semantic search; learned semantic index; knowledge graph embedding; linked open data; clustering techniques | clustering techniques; knowledge graph embedding; learned semantic index; linked open data; semantic search | English | 2022 | 2022-07 | 10.3390/app12136713 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Lightweight Deep Learning for Road Environment Recognition | Featured Application The system proposed in this paper provides a new idea for the recognition algorithm of road environments in safety-assisted driving systems, and subsequently improves the existing algorithm to reduce the computational cost and improve accuracy. With recent developments in the field of autonomous driving, recognition algorithms for road environments are being developed very rapidly. Currently, most of the network models have good recognition rates, but as the accuracy rate increases, the models become more complex and thus lack real-time performance. Therefore, there is an urgent need to propose a lightweight recognition system for road environments to assist autonomous driving. We propose a lightweight road environment recognition system with two different detection routes based on the same backbone network for objects and lane lines. The proposed approach uses MobileNet as the backbone network to acquire the feature layer, and our improved YOLOv4 and U-Net allows the number of parameters of the model to be greatly reduced and combined with the improved attention mechanism. The lightweight residual convolutional attention network (LRCA-Net) proposed in this work allows the network to adaptively pay attention to the feature details that need attention, which improves the detection accuracy. Finally, the object detection model and the lane line detection model of this lightweight road environment detection system evaluated on the PASCAL VOC dataset and the Highway Driving dataset show that their mAP and mIoU reach 93.2% and 93.3%, respectively, achieving excellent performance compared to other methods. | Liang, Han; Seo, Suyoung | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | Seo, Suyoung/AAB-8465-2020; Liang, Han/HPC-7877-2023 | 57222620902; 35198914000 | shto613@knu.ac.kr;syseo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.7 | 2025-06-25 | 7 | 8 | object detection; lane detection; attention mechanism; lightweight network | LANE DETECTION | attention mechanism; lane detection; lightweight network; object detection | English | 2022 | 2022-03 | 10.3390/app12063168 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
