| ○ | Conference paper | Enhancing Graph-Based Vulnerability Detection through Standardized Deep Learning Pipelines | Identifying vulnerable code is crucial to software system security. With the rise of deep learning, graph neural networks (GNNs) have received much attention for detecting vulnerabilities. While many studies aim to enhance GNN performance by refining graph structures, improving datasets, or optimizing model architectures, three key questions remain unanswered: 1) How do simple graph structures impact model performance? 2) How similar are artificially generated datasets to vulnerable code in the real world? 3) Does a more complex model provide better benefits in vulnerability detection? To find answers to these questions, we did experiments to show how basic graph structures affect GNN models and give guidelines on how to choose datasets. In addition, we introduce VulGCANet, a model with a relatively simple architecture that utilizes code property graphs and combines Graph Convolutional Networks (GCN) and Graph Attention Network (GAT) layers for vulnerability detection. The experimental results demonstrate that VulGCANet exhibits 30% improvements in recall while performing similarly to other graph neural network-based models, highlighting the importance of reducing the complexity of GNN model architectures in graph-based vulnerability detection. These findings provide valuable insights for advancing GNN-based vulnerability detection efforts. © 2024 IEEE. | Hao, Jiashun; Kwon, Young-Woo | Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea; Kyungpook National University, School of Computer Science and Engineering, Daegu, South Korea | 59919742400; 57208480210 | ej2975589@knu.ac.kr; | Proceedings of the IEEE International Conference on Trust, Security and Privacy in Computing and Communications, TrustCom | 2324-898X | 2024 | 0 | 2025-06-11 | 0 | deep learning; graph neural networks; program representations; Vulnerability detection | Deep neural networks; Graph algorithms; Network theory (graphs); Deep learning; Graph neural networks; Graph structures; Graph-based; Modeling architecture; Neural network model; Program representations; Simple++; Software-systems; Vulnerability detection; Graph neural networks | English | Final | 2024 | 10.1109/trustcom63139.2024.00174 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | Enhancing Load Forecasting by Clustering in Distributed Microgrids Based Energy Internet Framework | The intermittent nature of distributed renewable en-ergy sources and varying patterns of end-user loads in microgrids necessitate the manufacturers to accommodate unforeseen and expected fluctuations in energy consumption and production. Lack of accurate load forecasting may result in ineffective harnessing and storage of renewable energy and complicates energy trading and dynamic pricing. Existing literature on load forecasting of microgrids is limited to single microgrids, and the possibility of inter-microgrid communication is not addressed sufficiently. This study explores the enhancement of load fore-casting in an Energy Internet (EI) framework among multiple interconnected microgrids. A novel approach is proposed which integrates k-means clustering with Support Vector Regression (SVR) to forecast the load in the EI. We also investigate the influence of the communication network of the EI in improving short-term load forecasting (STLF). © 2024 IEEE. | Vijayan, Anjana; Yang, Jung-Min | School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, South Korea | 59463425800; 57208450551 | 9th IEEE/ACIS International Conference on Big Data, Cloud Computing, and Data Science, BCD 2024 | 0 | 2025-05-07 | 0 | communication networks; Energy Internet (EI); load forecasting; microgrids; support vector regression | Clusterings; Communications networks; Distributed renewables; End-users; Energy consumption and production; Energy internet; Load forecasting; Microgrid; Support vector regressions | English | Final | 2024 | 10.1109/bcd61269.2024.10743098 | 바로가기 | 바로가기 | |||||||||||||||||||

| ○ | ○ | Proceedings Paper | Enhancing Microcontroller Security Through Volatile Memory-Resident Encrypted Code | This paper presents a novel approach to enhancing microcontroller security by storing code in an encrypted format within flash memory and executing it from volatile memory. This method addresses critical vulnerabilities associated with executing code directly from non-volatile flash memory, such as susceptibility to reverse engineering and bit-level manipulation attacks. By decrypting sensitive code only during execution and performing cyclic redundancy checks to verify integrity before execution, the proposed approach significantly reduces the risk of unauthorized access and tampering. Additionally, the implementation of address space layout randomization during execution further enhances security by dynamically allocating memory for decrypted code. This study demonstrates the effectiveness of the proposed method in mitigating common security threats in embedded systems, with potential applications in automotive electronics, IoT devices, and other critical infrastructures. Future work may explore the integration of various encryption techniques and advanced security measures to further strengthen microcontroller security. | Kim, Minjung; Park, Daejin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | 58897306800; 55463943600 | boltanut@knu.ac.kr; | 2024 IEEE CONFERENCE ON DEPENDABLE AND SECURE COMPUTING, DSC | 0 | 2025-05-07 | 0 | 0 | security; embedded system; encryption; linker; firmware | embedded system; encryption; firmware; linker; security | Flash memory; Microcontrollers; Reverse engineering; Static random access storage; Address space layout randomizations; Bit level; Cyclic redundancy check; Embedded-system; Linker; Memory-resident; Nonvolatile; Security; Unauthorized access; Volatile memory; Firmware | English | 2024 | 2024 | 10.1109/dsc63325.2024.00028 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||||

This CF reflects light of specific wavelengths for desired colors while absorbing the rest. We assess color purity and accuracy using linear plots in Ansys Lumerical FDTD and chromaticity diagrams. Additionally, to focus this filtered light at various spots on the same plane, we design a metalens array in Ansys Lumerical FDTD and analyze its focusing profile. © 2024 SPIE. | Fizan, Muhammad; Noureen, Sadia; Khaliq, Hafiz Saad; Mahmood, Nasir | Department of Electrical Engineering, Information Technology University of the Punjab (ITU), Lahore, 54000, Pakistan; Department of Electrical Engineering, Information Technology University of the Punjab (ITU), Lahore, 54000, Pakistan; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; Innovative Technologies Laboratories (ITL), King Abdullah University of Science and Technology (KAUST), Thuwal, 23955, Saudi Arabia | 58806526400; 57808658700; 56725698200; 57532706000 | Proceedings of SPIE - The International Society for Optical Engineering | 0277-786X | 13012 | 0 | 2025-05-07 | 0 | Augmented Reality (AR); Color Filter; Immersive Experience; Metalens Array; Nanoscale Manipulation; Virtual Reality (VR); Visual Quality | Color; Image enhancement; Image resolution; Virtual reality; Augmented reality; Color accuracy; Color filters; Immersive; Immersive experience; MetaLens; Metalens array; Nanoscale manipulations; Virtual reality; Visual qualities; Augmented reality | English | Final | 2024 | 10.1117/12.3022098 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Article | Enhancing the Quality and Fruit Yield of Sweet Cherry (Prunus Avium) Cultivars by Foliar Application of Boron | A deficiency of boron can be observed mostly in sandy soil with a high pH level and with minimum soil organic matter. Being a significant micronutrient, its deficiency may decrease the photosynthetically active emission and absorption by leaves. It helps in the transport of photosynthetic foodstuffs from foliar parts to meristematic tissues in green parts and roots ensuring leaf, shoot, fruit, and seed formation. An experiment on sweet cherry cultivars ('Sasha', 'Stella,' and 'Sunburst') assigned to the main plot and boron levels (0%, 0.25%, 0.50%, 0.75%, and 1%) subjected to subplot was carried out at the Kalam Summer Station, Agriculture Research Institute, Swat, Pakistan. Among the cultivars, maximum leaf area (cm(2)), fruit diameter, percent pulp, total soluble solids (degrees Brix), titratable acidity (%), and total sugars (%) with the minimum number of fruit kg(-1) was recorded in sweet cherry cultivar 'Sunburst.' The maximum fruit set (%), and yield (kg.plant(-1)) with minimum fruit drop (%) were recorded in the sweet cherry cultivar 'Stella.' Regarding boron concentration, maximum leaf area (cm(2)), fruit set (%), fruit diameter (cm), yield (kg.plant(-1)), percent pulp (%), total soluble solids (degrees Brix), total sugars (%) with minimum fruit drop (%), and the number of fruit kg(-1) was recorded in sweet cherry cultivars sprayed with 1% of boron. However, the maximum titratable acidity (%) was recorded in control treatments. Sweet cherry cultivars 'Sunburst' and 'Stella' sprayed with 1% boron showed the best results regarding yield and quality fruits production under the agro-climatic condition of Swat Valley. | Sajid, Muhammad; Basit, Abdul; Shah, Syed Tanveer; Khan, Ayesha; Ullah, Izhar; Bilal, Muhammad; Khan, Muhammad Suleman; Khan, Waleed | Univ Agr Peshawar, Fac Crop Prod Sci, Dept Hort, Peshawar 25120, Pakistan; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Univ Hazara, Dept Agr, Mansehra, Pakistan; Ondokuz Mayis Univ, Fac Agr, Dept Hort, Samsun, Turkiye; Kyungpook Natl Univ, Dept Appl Biosci, Lab Crop Prod, Daegu 41566, South Korea | Shah, Syed Tasadaque/AAB-4890-2021; Basit, Abdul/AAX-2414-2021; Bilal, Muhammad/AET-1048-2022; Ullah, izhar/MYR-3437-2025; Khan, Ayesha/NKP-0640-2025 | 57213926335; 58696991300; 56089730700; 57199716425; 57211559793; 57224853341; 59206463000; 57822855200 | abdulbasit97_lily@knu.ac.kr;msulemankhan25@aup.edu.pk; | APPLIED FRUIT SCIENCE | APPL FRUIT SCI | 2948-2623 | 2948-2631 | 66 | 2 | SCIE | HORTICULTURE | 2024 | N/A | 0.61 | 2025-05-07 | 2 | 2 | Deficiency; Micronutrient; Fruit quality; Sweet cherry; Fruit drop | APPLE; FERTILIZATION; CALCIUM; GROWTH; SPRAYS; TREES | Deficiency; Fruit drop; Fruit quality; Micronutrient; Sweet cherry | English | 2024 | 2024-04 | 10.1007/s10341-023-01023-2 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Enhancing Tractor Safety over rough Terrains: A Numerical Study of Steering Instability | Tractor overturn accidents pose a significant safety concern in agriculture, particularly in Korea where small tractors navigate challenging terrains like slippery fields and steep slopes. The risk stems from steering instability induced by bouncing and sliding, impacting both tractor safety and trajectory tracking precision in autonomous driving. The agricultural industry is shifting towards alternative energy sources such as electric and hydrogen tractors, necessitating a reevaluation of safety concerns due to changes in the tractor's center of gravity. This study focuses on a numerical investigation of tractor steering instability, combining bouncing and sliding models based on Coulomb's friction theory. Numerical experiments are conducted, varying parameters like travel velocity, static friction coefficient, bump length, and turning radius. A turning test evaluates the fundamental steering performance. Simulation results demonstrate that bouncing and sliding reduce cornering force, deviating from the desired trajectory. Operating the tractor on steep slopes exacerbates steering instability, potentially leading to overturn accidents under unfavorable conditions. These findings provide crucial insights for improving tractor safety in challenging agricultural settings. © 2024 ASABE Annual International Meeting.

| ○ | Conference paper | Evaluating the Performance of Light Gradient Boosting Machine in Merging Multiple Satellite Precipitation Products Over South Korea | Precipitation information with high accuracy plays a crucial role in hydrology and water resources management. With the advance in technology, satellite precipitation products (SPPs) provide an unprecedented opportunity for monitoring the spatial and temporal variation of precipitation from space. However, SPPs still present a low performance with high uncertainty. To overcome this problem, the current study aims to produce a new reanalysis of precipitation data by integrating information from observation data with multiple SPPs over South Korea under the aid of a fast and high-performance machine learning-based, namely a light gradient boosting machine. In addition, other statistical merging methods were also carried out to highlight the robustness of the machine learning-based algorithm. To examine the accuracy of merging precipitation products, observed data from 64 automated synoptic observation system rain gauge stations were collected and compared with merging precipitation products. A high agreement between merging precipitation data generated from the machine learning-based approach with observation was witnessed through several continuous criteria and categorical indicators. The results from this study point out that light gradient boosting machine not only has the capability in merging multi-sources precipitation but also it could provide extraordinary rainfall information for the region of interest, especially in areas with low observed station density. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Nguyen, Giang V.; Le, Xuan-Hien; Van, Linh Nguyen; Jung, Sungho; Choi, Chanul; 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 | 57297771000; 57209735659; 57297359100; 57209733155; 58613779200; 35069799400 | leegiha@knu.ac.kr; | Lecture Notes in Civil Engineering | 2366-2557 | 344 LNCE | 5.19 | 2025-04-16 | 1 | Light gradient boosting machine; Machine learning; Merging; Satellite precipitation | Adaptive boosting; Image segmentation; Information management; Machine learning; Rain; Rain gages; Satellites; Water resources; Gradient boosting; Light gradient boosting machine; Light gradients; Machine-learning; Multiple satellites; Performance; Precipitation data; Satellite precipitation; Satellite precipitation products; South Korea; Merging | English | Final | 2024 | 10.1007/978-981-99-2345-8_52 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Evaluation of Anti-Helicobacter pylori Activity of Novel Lactic Acid Bacteria; [신규 젖산균을 활용한 Anti-Helicobacter pylori 활성] | In this study, we aimed to isolate and identify strains of lactic acid bacteria from kkakdugi, to validate their potential use as alternative therapeutic agents against Helicobacter pylori. Eleven strains were identified, including Lactobacillus plantarum, Pediococcus pentosaceus, Lactobacillus brevis, Pediococcus acidilacti, and Leuconostoc mesenteroides. The paper disk method and urease inhibition activity were used to verify anti-H. pylori activity. Without pH adjustment, most strains exhibited an average inhibitory zone of 13.68 mm. However, when the pH was adjusted to 7.0, some strains showed inhibitory zones ranging from 11.65 to 13.15 mm. Nevertheless, upon comparison, it was observed that the antimicrobial activity was higher when the pH was not adjusted. On the other hand, antimicrobial activity against H. pylori G88026 strain was exhibited regardless of the pH. The results of urease inhibition confirmed a significant reduction of approximately 60∼90% in urease activity when the lactic acid bacterial culture supernatant was added. Except for the Lactobacillus sakei strain, the remaining strains exhibited potent urease inhibition activity. This suggests that the lactic acid bacteria isolated in this study could be promising candidates as alternative therapeutic agents against H. pylori. © 2024 The Korean Society of Food Science and Nutrition. | Kim, Ji-Hye; Jung, Sung-Keun; Cho, Young-Je; Kim, Byung-Oh | School of Food Science, Kyungpook National University, South Korea; School of Food Science, Kyungpook National University, South Korea, Research Institute of Tailored Food Technology, South Korea; School of Food Science, Kyungpook National University, South Korea, Research Institute of Tailored Food Technology, South Korea; School of Food Science, Kyungpook National University, South Korea, Research Institute of Tailored Food Technology, South Korea | 59089372000; 35310491400; 55265396300; 7501567571 | kimb@knu.ac.kr; | Journal of the Korean Society of Food Science and Nutrition | 1226-3311 | 53 | 5 | 0 | 2025-05-07 | 0 | antimicrobial; Helicobacter pylori; kkakdugi; lactic acid bacteria; urease | Korean | Final | 2024 | 10.3746/jkfn.2024.53.5.485 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | Evaluation of Displacement of an L-shaped Concrete Specimen using Recurrent Neural Networks | In engineering, most structural elements are damaged locally during fabrication or maintenance. Under different loading conditions, such localized damage will further expand into larger cracks and cause structural collapse. As a result, identifying the displacement under various loads in the structural elements is critical in the risk assessment of engineering structures. The objective of the present paper is to propose a deep-learning model to examine the displacement of L-shaped concrete specimens under loading conditions. The three state-of-theart models such as Simple RNN, LSTM, and GRU are built and trained based on load-displacement data. The experimental results show that the R2 values obtained from the Simple RNN, LSTM, and GRU models are 0.9967, 0.6169, and 0.5291, respectively. This proves that Simple RNN is superior to LSTM and GRU in the task of predicting the load-displacement relationship. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024. | Nguyen, Quoc H.; Doan, Vi T.

| ○ | Article | Evaluation of DNA and cell damage induced by intense pulsed light in Pseudomonas aeruginosa; [Intense pulsed light에 의해 유도된 Pseudomonas aeruginosa의 DNA 및 세포 손상에 대한 평가] | The present study aimed to evaluate the bactericidal effect of intense pulsed light (IPL) on Pseudomonas aeruginosa and DNA and cell damage induced by IPL treatment. Microbial inactivation by IPL improved with higher voltages and prolonged exposure, showing a reduction of approximately 6.0 log for 90 s at 600 V and 60 s at 800 V. The temperature changes during IPL treatment on P. aeruginosa cells were 1.05oC for 90 s at 600 V and 1.57oC for 60 s at 800 V. IPL treatment resulted in the accumulation of double-strand breaks (DSBs), single-strand breaks (SSBs), and cyclobutane pyrimidine dimers (CPDs) in the DNA of P. aeruginosa cells. Transmission electron microscopy (TEM) confirmed that the structure of untreated cells was maintained, whereas disrupted membranes and ruptured internal tissues were observed in treated cells. These findings suggest that IPL treatment effectively inactivates P. aeruginosa and has potential applications in food sterilization. ©The Korean Society of Food Science and Technology. | Ryu, Hyeon min; Jeon, Je-Hyeok; Cheigh, Chan-Ick | Department of Food and Food Service Industry, Kyungpook National University, South Korea; Department of Food and Food Service Industry, Kyungpook National University, South Korea; Department of Food and Food Service Industry, Kyungpook National University, South Korea | 58719448300; 58631090700; 6506587023 | cic@knu.ac.kr; | Korean Journal of Food Science and Technology | 0367-6293 | 56 | 6 | 0 | 2025-05-07 | 0 | cyclobutane pyrimidine dimer; double-strand break; intense pulsed light; Pseudomonas aeruginosa | Korean | Final | 2024 | 10.9721/kjfst.2024.56.6.814 | 바로가기 | 바로가기 |
