| ○ | Book chapter | Urea breath test | The urea breath test (UBT) is a noninvasive, simple, and safe test that provides excellent accuracy both for the initial diagnosis of Helicobacter pylori (H. pylori) infection (high sensitivity: 90-100% and specifcity: 90-100%). This test is based on the organism's urease activity, which liberates carbon dioxide (CO2) from urea and produces ammonia to buffer its acidic environment. Ingestion of labeled urea results in the production of labeled CO2, which then can be detected in the breath. Urea can be labeled with two different isotopes, 14C (the radioactive isotope) or 13C (the nonradioactive stable isotope). The methodology of the UBT has been changed including the dose of labeled urea used, the type of test meal, the time of breath collection, the cutoff values, and the equipment adapted to measure isotope enrichment. This test is also used to ascertain the eradication, and it is recommended for the "test-and-treat" strategy. Even though there is no defnitive standardization of this test and the quantitative results may be infuenced by sex, age, body mass index; especially obesity, smoking, gastric atrophy and intestinal metaplasia, and even socioeconomic status, UBT is regarded as agold standard noninvasive method for H. pylori diagnosis. © Springer Nature Singapore Pte Ltd. 2023.

| ○ | Conference paper | Use of Disdrometer Dataset to Detect Kinetic Energy Expenditure and Rainfall Intensity Relationships | Soil is a vital component for supporting life on Earth and is substantially responsible for the operation of any ecological system. Soil erosion is a global problem because it has resulted in the destruction of agricultural land. Raindrops contacting the soil surface may cause soil separation. This process may be identified by assessing the rainfall kinetic energy (KE). Since direct measurements of KE are challenging, statistical formulas are often employed as an alternative option to estimate the KE using rainfall intensity (RI), which significantly influences soil erosion and is very simple to detect. In this study, we collected a rainfall dataset using a laser-based device (OTT Parsivel2 optical disdrometer) between June 2020 and December 2021 in Sangju City (Korea) to analyze the property of KE-RI relationship. A total of 37 rainfall events were selected and used for the formation of KE-RI equations. We derived three KE–RI equations in each group based on the three different rainfall intensity groups. Power-law, linear, and polynomial models were used to link KE to RI, and the best correlation between KE and RI was determined using a power-law form. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Van, Linh Nguyen; Le, Xuan-Hien; Nguyen, Giang V.; Yeon, Minho; Kim, Younghoon; Lee, Giha | Kyungpook National University, Sangju, South Korea; Kyungpook National University, Sangju, South Korea, Thuyloi University, Hanoi, Viet Nam; Kyungpook National University, Sangju, South Korea; Kyungpook National University, Sangju, South Korea; Kyungpook National University, Sangju, South Korea; Kyungpook National University, Sangju, South Korea | 57297359100; 57209735659; 57297771000; 57223436971; 58613627800; 35069799400 | leegiha@knu.ac.kr; | Lecture Notes in Civil Engineering | 2366-2557 | 344 LNCE | 0 | 2025-04-16 | 0 | Korea; OTT Parsivel<sup>2</sup> disdrometer; Rainfall kinetic energy | Erosion; Kinetics; Rain; Soils; Disdrometers; Ecological systems; Energy expenditure; Global problems; Intensity equation; Korea; OTT parsivel2 disdrometer; Rainfall intensity; Rainfall kinetic energy; Soil erosion; Kinetic energy | English | Final | 2024 | 10.1007/978-981-99-2345-8_51 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Using multi-scale feature predictions for FPN architecture based real-time semantic segmentation | Semantic segmentation is a challenging topic that requires the categorization of every pixel of input images. When each pixel output is computed by neighborhood values from the previous stage, the field of views is directly affected by feature extraction. A large receptive field captures many classes for a single shoot, so it leads to poor extraction. When a receptive field is small, it can not cover the global information of large objects. Feature pyramid network (FPN) includes multi-scale features to process information. Four features with different receptive views are suitable for extracting a long range of objective sizes. However, the feature aggregation of the FPN method is not optimal when it demands huge computation resources and reduces rich semantic information by concatenating all features together. In order to address the above limitations, this paper proposes multi-scale feature predictions based on the traditional FPN method to improve the model's performance and efficiency. The proposed decoder comprises two predictions to effectively process highlighted information from each feature. A pair of the feature pyramid is selected to generate one prediction. The context and spatial branches have different contributions to the progression of information-sharing. When the atrous spatial pyramid pooling is applied to the context path to obtain denser information, the spatial branch is basically processed by a convolution layer to maintain the coarse information. The model is trained and evaluated by different public datasets. We achieved outstanding results with 76.2 % mIoU and 65 FPS on Cityscapes, and 43.5 % mIoU on the Mapillary Vistas dataset. | Quyen, Van Toan; Kim, Min Young | Kyungpook Natl Univ, Elect & Elect Engn, Daegu, South Korea | 57215669249; 56739349100 | yersin@knu.ac.kr;minykim@knu.ac.kr; | 2024 FIFTEENTH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS, ICUFN 2024 | 2165-8528 | 2165-8536 | 0 | 2025-05-07 | 0 | 0 | Semantic segmentation; feature pyramid network; multiscale prediction; real-time application | feature pyramid net-work; multiscale prediction; real-time application; Semantic segmentation | Large datasets; Feature pyramid; Feature pyramid net-work; Multi-scale features; Multiscale predictions; Net work; Network methods; Pyramid network; Real-time application; Receptive fields; Semantic segmentation; Semantic Segmentation | English | 2024 | 2024 | 10.1109/icufn61752.2024.10625449 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Conference paper | Validating Time Serial Images for Emotion Recognition | The pig emotion recognition (PER) reads the pig's emotions through the surveillance camera system. It can notify the husbandry workers if the system finds the pig's negative emotions. The PER is the idealistic system for pig husbandry workers, but practically applying the system is quite challenging without a suitable PER dataset. The pigs in the cage seldom move around the area, and the images captured are almost identical through the surveillance camera in the time series. The recurrent convolution neural networks may solve the problem. Still, with the single inputs to the architecture, the time serial images of the PER dataset produce misleading and biased experimental narration without a proper preprocessing method. To have adequate results from the time-serial imaging dataset, we propose the semi-shuffling approach to manage our PER dataset rather than what some researchers normally fully-shuffle the dataset without inspecting time-serial images. We have 98.45% validating accuracy as with fully-shuffling whole training and testing groups, but the validating accuracy reduces to 75.97% after applying the semi-shuffling training and testing dataset. © 2024 IEEE. | Kim, Jung Hwan; Han, Dong Seog | School of Electronics and Electrical Engineering, Kyungpook National University, South Korea; School of Electronics and Electrical Engineering, Kyungpook National University, South Korea | 57222321332; 7403219442 | dshan@knu.ac.kr; | 6th International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2024 | 0 | 2025-04-16 | 0 | Agriculture; Cameras; Recurrent neural networks; Security systems; Speech recognition; Statistical tests; Camera systems; Convolution neural network; Emotion recognition; Pre-processing method; Serial images; Single input; Surveillance cameras; Times series; Training and testing; Workers'; Emotion Recognition | English | Final | 2024 | 10.1109/icaiic60209.2024.10463346 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Book chapter | Valorization of Agro-food Wastes and Byproducts into Bioactive Peptides | Agro-food wastes are generated from various plant, dairy, and fisheries commodities and their by-products. A large portion of food waste can remain in the dumping sites without proper recycling and valorization approaches. Improper disposal of those domestic and industrial wastes can pose a harmful threat and detrimental effects on the surrounding environment. Although those wastes and waste streams are rich in valuable compounds, especially bioactive peptides (BAP) and nutraceuticals that are utilized as value-added alternatives for various health-promoting activities, proper valorization was neglected due to research and knowledge scarcity. In recent reports, the recycling-based utilization of these wastes or valorization to recover BAP is of great interest to multiple scientific communities. However, there still exists a much-hidden research avenue to explore for sustainable recycling and valorization of those neglected agro-food waste into valuable BAP through waste to wealth strategy. In this chapter, we systematically discussed and compared the current advancement of agro-food waste valorization based on their types, agro-sources, and bioactivity and critically analyzed different methods of recovery, particularly microbes and fermentation-associated conversion. Finally, the technical challenges for efficient utilization of these sustainable practices are also focused on. This updated appraisal will extract integrated and contemporary approaches for sustainable agro-food waste valorization toward the circular economy. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. | Ahsan, S.M.; Choi, Hyong Woo; Injamum-Ul-Hoque, Md.; Mezanur Rahman, Md.; Hritik, Tafim Hossain; Mahamud, A.

| ○ | Article | Variation in Hematological Parameters Associated with Janus Kinases 1 and 2 Inhibition in a Patient with Atopic Dermatitis | Baricitinib, janus kinase (JAK) 1/2 inhibitor, can significantly improve the patients with moderate to severe atopic dermatitis (AD). However, the concerns about its hematological safety have raised. A 57-year-old man with severe AD started taking baricitinib due to ineffectiveness and side effects of conventional treatments. After 16 weeks, hemoglobin level decreased to 7.5 g/dL. He started taking folate and multivitamin supplements for anemia with baricitinib suspension, and hemoglobin level increased after 2 weeks. Baricitinib affects hemoglobin levels and other hematological parameters by inhibiting the action of erythrocyte production, which is promoted by JAK2 signaling. When treating AD patients with baricitinib, periodic blood test is required to confirm the occurrence of hematological abnormalities. © 2024 Korean Dermatological Association.

| ○ | ○ | Article | Variations of VHCF Characteristics by Microstructure of a Spring Steel to UNSM Treatment | The bainitic structure resulting from the austempering of spring steel exhibits high strength and ductility. On the other hand, there appears to be no study on the effects of very high cycle fatigue (VHCF) and ultrasonic nanocrystal surface modification (UNSM) of this bainite structure. Therefore, this study compared the fatigue properties of VHCF using spring steel with bainitic and martensitic structures and bearing steel data. This study analyzed the characteristics of microstructure transformation associated with the heat treatment cycles and studied and evaluated the fatigue strength characteristics because of the UNSM in terms of fracture mechanics method and fracture surface analysis through electron backscatter diffraction, scanning electron microscopy fracture analysis, and energy-dispersive spectroscopy analysis. The fatigue limit of UNSM-treated spring steel was improved significantly by approximately 33% to 50% compared to the fatigue test results of the untreated material in the VHCF. In the long life range of bainized spring steel, fish-eye cracks appear in the form of the fine granular area, and fatigue cracks occur in the form of fish-eye cracks that occur in the bainite facet and matrix, resulting in a significant increase in fatigue strength and fatigue life. | Nahm, Seung-Hoon; Suh, Min-Soo; Suh, Chang-Min | Korea Res Inst Stand & Sci, Daejeon, South Korea; Kyoto Univ, Kyoto, Japan; Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea | 35220422900; 15060716600; 7102970945 | cmsuh@knu.ac.kr; | JOURNAL OF OCEAN ENGINEERING AND TECHNOLOGY | 1225-0767 | 2287-6715 | 38 | 5 | 0 | 2025-05-07 | 0 | 0 | Spring steel; Bainite; Martensite; Austempering; Very high cycle fatigue (VHCF); Ultrasonic nanocrystal surface modification (UNSM) | FATIGUE CHARACTERISTICS; BEHAVIOR; BAINITE | Austempering; Bainite; Martensite; Spring steel; Ultrasonic nanocrystal surface modification (UNSM); Very high cycle fatigue (VHCF) | English | 2024 | 2024-10 | 10.26748/ksoe.2024.058 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Vehicle Velocity Control System for Multi-Vehicle Collision Avoidance Based on Optimal Collision Point; [최적 충돌 지점 기반 다중 차량 충돌 방지를 위한 차량 속도 제어 시스템] | This paper proposed a collision avoidance method with vehicle longitudinal velocity control based on multi-vehicle collision points. We estimated the position and shape of the object vehicles with collision risk through sensors, such as LiDAR and cameras. Then, the collision point was determined from the object data, and a Kalman filter was applied to estimate the object vehicle. The optimal collision distance was estimated by calculating the collision risk for the collision point of the multi-object vehicle. Afterward, a collision avoidance system was implemented through a longitudinal control technique using optimal collision distance and time gap. The proposed method was verified through multi-vehicle collision avoidance scenario-based simulation. © 2024 Korean Society of Automotive Engineers.

| ○ | ○ | Proceedings Paper | VERIFICATION OF PROTON BEAM RANGE USING PHOTOPOLYMERIZED PMMA-BASED PLASTICS SCINTILLATOR | Due to the high linear energy transfer (LET) and a Bragg peak, proton radiation therapy enables targeted radiation treatment focused on cancer cells while reducing exposure to normal tissues. However, various studies are needed to measure proton energy accurately, as uncertainties can arise depending on the energy of the proton beam and the characteristics of human tissue. In this work, we developed an optical dosimeter to verify the range of the proton beam using a PMMA (poly-methyl methacrylate)based tissue-equivalent plastic scintillator with a CMOS (complementary metal-oxide-semiconductor) camera. The Bragg peak position was confirmed through image processing after photographing the scintillation light generated during proton beam irradiation with the camera. Additionally, the correct Bragg peak was measured by correcting for the quenching effect of the scintillator. The proton beam's energy was adjusted using an aluminum degrader, and the experimental results were verified by comparing them with the Geant4 simulation. The relationship between the simulated and measured proton beam ranges was R-2 = 0.99, confirming the validity of KOMAC's (Korea Multi-purpose Accelerator Complex) 102 MeV proton beam for range verification. | Kim, Gwangsoo; Kim, Hongjoo; Kim, Sunghwan | Kyungpook Natl Univ, Daegu, South Korea; Cheongju Univ, Cheongju, South Korea | 57208178031; 58483690400; 36165569900 | ACTA PHYSICA POLONICA B PROCEEDINGS SUPPLEMENT | 1899-2358 | 2082-7865 | 17 | 7 | 0 | 2025-05-07 | 0 | 0 | DOSIMETRY | Hadrons; Ionomers; Photons; Scintillation; Scintillation counters; Bragg peaks; Cancer cells; Energy; High linear energy transfers; Normal tissue; Plastic scintillator; Poly(methyl methacrylate); Poly-methyl methacrylates; Proton radiation therapy; Radiation treatments; Proton beam therapy | English | 2024 | 2024 | 10.5506/aphyspolbsupp.17.7-a6 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Conference paper | Verification test for harvest supplement by post-sowing of garlic in South Korea | After planting the garlic in winter season, the farmer spent additional time and labor to find out miss-planted pot and non-germinated pot for supplement the total yield of garlic in South Korea. With the intuition aspect, post-planted garlic clove has a difficulty of growing and the differences between early and late planted garlic can be reflected by the quality of garlic in harvest season. In this study, the physical characteristics of conventionally planted and post-planted garlic compared and the effect of post-planted operation was discussed. The garlic cloves were planted on late November of 2023 in conventional method and irrigation and management also conducted with it. After taking terms of germination, missed and non-germinated pots were investigated and additional garlic cloves were prepared for post-planted experiment. The hundred of garlic cloves were post-planted in randomly on 1st December 2023 and management of whole field was performed in general. As an interim finding, planted garlics were taken on 19th April 2023, a diameter of main stem, vertical length of garlic, number of leave, width and length of first two leave were selected as physical characteristics for the comparison. The degraded physical characteristics of post-planted garlic were found except in number of leave, a diameter of main stem and vertical length were 72.6% and 76.58% less than that of conventionally planted garlic. The width and length of leaf was 50% less growth than the conventionally planted garlic. However, garlic with an awareness shape was not recognized and similar level of the number of leave was found which indicated that they were in same phenological growth stage. © 2024 ASABE Annual International Meeting.

| ○ | Article | Visible light-induced photocatalytic degradation of tetrabromobisphenol A on platinized tungsten oxide | In this study, we investigated the degradation of the flame retardant tetrabromobisphenol A (TBBPA) using platinized tungsten oxide (Pt/WO3), synthesized via a simple photodeposition method, under visible light. The results of degradation experiments show a significant enhancement in TBBPA degradation upon surface platinization of WO3, with the degradation rate increasing by 13.4 times compared to bare WO3. The presence of Pt on the WO3 surface stores conduction band electrons, which facilitates the two-electron reduction of oxygen and enhances the production of valence band holes (hVB+) and hydroxyl radicals (●OH). Both hVB+ and ●OH are significantly involved in the degradation of TBBPA in the visible light-irradiated Pt/WO3 system. This was verified through fluorescence spectroscopy employing coumarin as a chemical probe and oxidizing species-quenching experiments. The analysis of degradation products and their toxicity assessment demonstrate that the toxicity of TBBPA-contaminated water is significantly reduced after Pt/WO3 photocatalysis. The degradation rate of TBBPA increased with increasing Pt/WO3 dosage, reached an optimum at a Pt content of 0.5 wt%, but decreased with increasing TBBPA concentration. The decrease in degradation efficiency of Pt/WO3 was minor, both in the presence of various anions and after repeated use. This study proposes that Pt/WO3 is a viable photocatalyst for the degradation of TBBPA in water under visible light. © 2024 Elsevier Ltd | Tarif, Ahmed; Tran, Khen Duy; Ahn, Yong-Yoon; Kim, Kitae; Kim, Jungwon; Park, Hyunwoong | School of Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; Department of Environmental Sciences and Biotechnology, Hallym University, Chuncheon, Gangwon-do, 24252, South Korea; Korea Polar Research Institute (KOPRI), Incheon, 21990, South Korea; Korea Polar Research Institute (KOPRI), Incheon, 21990, South Korea; Department of Environmental Sciences and Biotechnology, Hallym University, Chuncheon, Gangwon-do, 24252, South Korea; School of Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea | 59211438300; 58148271700; 39361158700; 57102106700; 55720139700; 7601565583 | jwk@hallym.ac.kr;hwp@knu.ac.kr; | Chemosphere | 0045-6535 | 363 | 0.38 | 2025-05-07 | 2 | Flame retardant; Platinized tungsten oxide; Tetrabromobisphenol A; Toxicity assessment; Visible light | Catalysis; Flame Retardants; Light; Oxidation-Reduction; Oxides; Photochemical Processes; Photolysis; Platinum; Polybrominated Biphenyls; Tungsten; Water Pollutants, Chemical; Degradation; Fluorescence spectroscopy; Oxides; Platinum; Toxicity; Water pollution; carbonic acid; chloride; coumarin; hydroxyl radical; nitrate; oxygen; phosphate; tetrabromobisphenol A; tungsten derivative; water; flame retardant; oxide; platinum; polybrominated biphenyl; tetrabromobisphenol A; tungsten; tungsten oxide; Degradation rate; Photo-deposition; Photocatalytic degradation; Platinized tungsten oxide; Simple++; Synthesised; Tetrabromobisphenol-A; Toxicity assessment; Visible light; Visible light induced; assessment method; flame retardant; fluorescence spectroscopy; induced response; light effect; photodegradation; probe; toxicity; visible spectrum; Article; bioaccumulation; centrifugation; chemical composition; controlled study; debromination; degradation; degradation kinetics; irradiation; light; light absorption; nonhuman; oxidation; oxidation reduction potential; pH; photocatalysis; reaction time; retention time; spectrofluorometry; surface property; suspension; synthesis; Tetrahymena pyriformis; ultra performance liquid chromatography; valence (chemistry); X ray diffraction; X ray photoemission spectroscopy; catalysis; chemistry; oxidation reduction reaction; photochemistry; photolysis; water pollutant; Tungsten compounds | English | Final | 2024 | 10.1016/j.chemosphere.2024.142785 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Vision-based Vertiport Marking Detection System for Precision Landing on a Vertiport | Contrary to existing airports in the suburbs, a vertiport is located in a complex urban area and has space limitations. Precision landing technology at a vertiport is essential for safe urban air mobility (UAM) operations in limited spaces. The U.S. Federal Aviation Administration (FAA) has recently released a symbol design for vertiport identification. However, research on the precision landing of a UAM vehicle using this symbol is still insufficient. We propose a vision-based system for detecting the FAA vertiport marking to ensure precision landing on a vertiport. After the existing fiducial marker detectors have been benchmarked, we establish a methodology that recognizes the vertiport marking, estimates the relative position and attitude through transformation, and visualizes the pose estimation results to instruments similar to the instrument landing system. Marking detection and pose estimation are validated experimentally by using cameras and drone flight tests. The results show the applicability of the proposed approach under the operating conditions for UAM. © ICROS 2024. | Heo, Hyeonjeong; Lee, Kyuman | Department of Robot and Smart System Engineering, Kyungpook National University, South Korea; Department of Robot and Smart System Engineering, Kyungpook National University, South Korea | 58888646100; 57193932345 | klee400@knu.ac.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 30 | 2 | 0.46 | 2025-04-16 | 1 | image processing; marker detection; precision landing; urban air mobility; vertiport | Image processing; Landing; Detection system; Federal Aviation Administration; Images processing; Marker detections; Pose-estimation; Precision landing; Urban air; Urban air mobility; Vertiport; Vision based; Air mobility | Korean | Final | 2024 | 10.5302/j.icros.2024.23.0190 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Conference paper | Visualizing Virtual Embedded Systems: Enhancing Renode with Interactive Board Simulations | As the complexity of embedded systems increases, traditional hardware testing methods are progressively being supplemented with advanced virtual simulations. Virtual simulation has become essential in automotive software development for system stability verification. Renode stands out for its ability to efficiently simulate complex interactions between embedded devices. However, its command-line interface (CLI) for debugging can be less intuitive. This paper proposes the integration of board visualization features into Renode to create a more user-friendly graphical user interface (GUI). This enhancement simplifies debugging, accelerates the verification cycle, and provides clearer insights into software behavior, thus improving overall productivity.

| ○ | Article | Voltage Angle Control for a BLDC Motor and Controller Gain Design; [BLDC 전동기의 전압각 제어 기법과 제어기 이득 선정법] | This paper introduces a voltage angle controlled Space Vector Modulation (SVM) strategy for Brushless DC(BLDC) motor operation. The conventional 6-step control method for BLDC motors encounters limitations as it can only utilize half of the inverter DC link voltage(Vdc/2). SVM control is implemented to overcome inverter voltage utilization. The voltage angle controller is mainly used in flux-weaking control and has the advantage of having only one current controller. In this paper, voltage angle control is applied in the constant torque region, and the closed-loop transfer function of voltage-angle controller is analyzed according to the response of gain, speed, and load. Bode plots are used for this analysis, leading to the identification of the gain value that effectively suppresses resonance. Furthermore, the study addresses speed control by adjusting the voltage magnitude, and the proposed method is validated through simulation and experimental results.

| ○ | ○ | Article | Voronoi Diagram-based USBL Outlier Rejection for AUV Localization | USBL systems are essential for providing accurate positions of autonomous underwater vehicles (AUVs). On the other hand, the accuracy can be degraded by outliers because of the environmental conditions. A failure to address these outliers can significantly impact the reliability of underwater localization and navigation systems. This paper proposes a novel outlier rejection algorithm for AUV localization using Voronoi diagrams and query point calculation. The Voronoi diagram divides data space into Voronoi cells that center on ultra-short baseline (USBL) data, and the calculated query point determines if the corresponding USBL data is an inlier. This study conducted experiments acquiring GPS and USBL data simultaneously and optimized the algorithm empirically based on the acquired data. In addition, the proposed method was applied to a sensor fusion algorithm to verify its effectiveness, resulting in improved pose estimations. The proposed method can be applied to various sensor fusion algorithms as a preprocess and could be used for outlier rejection for other 2D-based location sensors. | Sim, Hyeonmin; Joe, Hangil | Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, Daegu, South Korea; Kyungpook Natl Univ, Dept Smart Mobil Engn, Daegu, South Korea | ; Joe, Hangil/LOR-9635-2024 | 59236496000; 55848385500 | hgjoe@knu.ac.kr; | JOURNAL OF OCEAN ENGINEERING AND TECHNOLOGY | 1225-0767 | 2287-6715 | 38 | 3 | 0 | 2025-05-07 | 0 | 0 | USBL; Outlier detection; Voronoi diagram; Acoustic sensors | Acoustic sensors; Outlier detection; USBL; Voronoi diagram | English | 2024 | 2024-06 | 10.26748/ksoe.2024.049 | 바로가기 | 바로가기 | 바로가기 |
