| ○ | Article | A Solution Method for Nonlinear Monotone Equations via Hybrid Spectral Conjugate Gradient and Signal Recovery Problems | In this paper, we propose a method via hybrid spectral conjugate gradient to solve nonlinear monotone equations and signal recovery problems. This has been done using the hybrid conjugate gradient (CG) parameters of Dai-Yuan (DY), conjugate descent (CD), Hestenes-Stiefel (HS), Liu-Storey (LS) and the corresponding search direction of spectral conjugate gradient method. The search direction has proved to be adequately descent regardless of the step-size. Under reasonable assumptions, the convergence of the algorithm is established. Additionally, numerical tests are run on a set of benchmark test problems to illustrate the effectiveness and competitiveness of the new algorithm compared with other existing alternatives. Finally, some applications of the proposed algorithm are explored. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024. | Yusuf, Aliyu; Manjak, Nibron Haggai; Mohammad, Hassan; Kiri, Aliyu Ibrahim; Abubakar, Auwal Bala | Department of Science, School of Continuing Education, Bayero University Kano, Kano, 700241, Nigeria, Department of Mathematical Sciences, Faculty of Science, Abubakar Tafawa Balewa University Bauchi, Bauchi, Nigeria, Numerical Optimization Research Group, Department of Mathematical Sciences, Faculty of Physical Sciences, Bayero University Kano, Kano, 700241, Nigeria; Department of Mathematical Sciences, Faculty of Science, Abubakar Tafawa Balewa University Bauchi, Bauchi, Nigeria; Numerical Optimization Research Group, Department of Mathematical Sciences, Faculty of Physical Sciences, Bayero University Kano, Kano, 700241, Nigeria; Numerical Optimization Research Group, Department of Mathematical Sciences, Faculty of Physical Sciences, Bayero University Kano, Kano, 700241, Nigeria; Numerical Optimization Research Group, Department of Mathematical Sciences, Faculty of Physical Sciences, Bayero University Kano, Kano, 700241, Nigeria, Department of Mathematics and Applied Mathematics, Sefako Makgatho Health Sciences University, Ga-Rankuwa, Medunsa, Pretoria, 0204, South Africa, Nonlinear Dynamics and Mathematical Application Center, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea | 57225310022; 48662639000; 56624218300; 57222552478; 57195315186 | ayusuf.sce@buk.edu.ng; | Operations Research Forum | 2662-2556 | 5 | 2 | 0.54 | 2025-05-07 | 2 | Conjugate gradient method; Global convergence; Nonlinear monotone equations; Numerical experiments; Spectral gradient parameter | English | Final | 2024 | 10.1007/s43069-024-00326-8 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | A Star-Connected Multilevel Converter with Zigzag Transformer for E-STATCOM | The increased deployment of renewable resources in the grid can lead to instability due to frequency fluctuation. Integrating energy storage system(ESS) into the grid is one solution to alleviate this instability. Therefore, many studies have been conducted on power electronic facilities for stable power transmission by utilizing ESS. Among various power electronic facilities, the integration of an ESS into a static synchronous compensator(STATCOM) using a multilevel converter has been gaining attention. This paper presents a multilevel converter with a zigzag transformer for E-STATCOM. The overall control techniques for the proposed configuration are described and validated through simulation. © 2024 IEEE. | Kim, Jae-Myeong; Cui, Shenghui; Jung, Jae-Jung | Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Seoul National University, Department of Electrical and Computer Engineering, Seoul, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea | 57210835520; 56157479900; 55368433400 | mms01270@knu.ac.kr; | ECCE Europe 2024 - Energy Conversion Congress and Expo Europe, Proceedings | 0 | 2025-05-07 | 0 | Energy storage system(ESS); multilevel converter; static synchronous compensator(STATCOM); zigzag transformer | Chemical laboratories; DC-DC converters; Electric power transmission; Materials testing laboratories; Research laboratories; Energy; Energy storage system; Frequency fluctuation; Multilevel converter; Overall controls; Power-electronics; Power-transmission; Renewable resource; Storage systems; Zigzag transformer; Static synchronous compensators | English | Final | 2024 | 10.1109/ecceeurope62508.2024.10751832 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | ○ | Proceedings Paper | A Structural-Semantic Approach Integrating Graph-Based and Large Language Models Representation to Detect Android Malware | The Android operating system's dominance in the smartphone market cements its pivotal role in shaping contemporary connectivity and technological innovation, with the rate of application development increasing at an unprecedented rate. However, this rapid growth also presents challenges, as malicious actors exploit vulnerabilities to infiltrate systems with malware, posing substantial threats to individual users and organizations. Security experts continuously develop strategies and methods to address these challenges. However, the evolving nature of these attacks presents ongoing challenges to security measures aimed at detecting emerging malware. While deep learning methods offer promise by leveraging multi-level features for more adaptive malware detection, many existing approaches focus primarily on high-level features such as permissions and data flow, potentially limiting their longterm efficacy. To gain a deeper understanding of the nature of these attacks, it is crucial for existing approaches to pay more attention to the essential structural and semantic aspects of Android applications. We propose a multi-level technique utilizing graph-based representations to capture high-level structural information effectively. We extract detailed source-level information by integrating pre-trained large language models (LLMs), learning deeper syntax and semantic features. Combining both, we attribute the graph-based representation of Android applications with source-level features. Leveraging graph convolutional neural networks, we comprehensively process and analyze these graphs. Our proposed methods demonstrate superior results compared to existing and baseline approaches. This work offers an innovative approach to understanding malware at high structural, low source, and semantic levels, enhancing cybersecurity defenses against evolving threats in the dynamic landscape of Android security. | Khan, Irshad; Kwon, Young-Woo | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | Khan, Irshad/AAN-8522-2020; Kwon, Young-Woo/HGE-6607-2022 | 36166674500; 57208480210 | irshad.cs@knu.ac.kr;ywkown@knu.ac.kr; | ICT SYSTEMS SECURITY AND PRIVACY PROTECTION, SEC 2024 | 1868-4238 | 1868-422X | 710 | 2.88 | 2025-05-07 | 2 | 2 | Android malware; Graph attention network; Graph classification; Attributed graphs; LLM | Android malware; Attributed graphs; Graph attention network; Graph classification; LLM | Android malware; Computational linguistics; Convolutional neural networks; Cybersecurity; Deep learning; Graphic methods; Learning systems; Mobile security; Semantics; Android applications; Android malware; Attributed graphs; Graph attention network; Graph classification; Language model; Large language model; Malwares; Multilevels; Source level; Android (operating system) | English | 2024 | 2024 | 10.1007/978-3-031-65175-5_20 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | A study of 2νββ decay of 100Mo to the excited states of 100Ru at AMoRE-I | The AMoRE (Advanced Mo-based Rare process Experiment) aims to study not only the neutrino-less double beta (0νββ) decay but also the two-neutrino double beta (2νββ) decay using a cryogenic technique and consists of enriched 100Mo-based scintillating crystal detectors. The study of the 2νββ decay from 100Mo to excited states of 100Ru helps to understand nuclear matrix elements and nuclear models as well as to search for the bosonic (symmetric) fraction of the neutrino wave function. In AMoRE-I, we can select the double-coincidence events to suppress background level successfully. The half-life of the 2νββ decay of 100Mo to 0+1 state of 100Ru is measured to be {6.55 ±0.67 (stat)±0.45 (syst)} ×1020 year. The AMoRE-II, a large scale successor of the AMoRE-I, is under construction at 1000 m deep Yemilab, underground laboratory, aiming for a tonne-year exposure of 100Mo. A simulation has been initiated to measure the beta energy of the 0+1 transition in triple-coincidence events, and to verify events from the decay to the suppressed 2+1 excited state. © 2024 Author(s). | Ha, D.H.; Kim, H.J. | Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea | 57023186700; 58483690400 | hongjooknu@gmail.com; | AIP Conference Proceedings | 0094-243X | 3138 | 1 | 0 | 2025-05-07 | 0 | English | Final | 2024 | 10.1063/5.0206746 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | A Study of the Biological Activity of Tillandsia ionantha Extracts in LPS-Induced RAW 264.7 Cells; [LPS로 유도된 대식세포에서 틸란드시아 이오난사(Tillandsia ionantha) 추출물의 생리활성 탐색] | This study aimed to study the antioxidant and anti-inflammatory potential of Tillandsia ionantha, as a natural material by studying various physiological effects. T. ionantha is known for its strong anti-cancer activity and a high moisture absorption ability. T. ionantha was distilled with hot water (TID) and 70% ethanol (TIE) to obtain the relevant extracts. These extracts showed excellent antioxidant effects in terms of their electron-donating ability and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activity. After measuring the cell viability of the TID, TIE extracts, and indomethacin in RAW 264.7 cells, subsequent experiments were conducted. At a concentration of 500 μg/mL, TID and TIE extract inhibited nitric oxide production, by 23.09% and 25.74%, respectively. It was also confirmed that TID and TIE extracts decreased the expression of PGE2 and TNF-α in a concentration-dependent manner. Both TID and TIE extracts decreased the expression of inducible nitric oxide synthase and cyclooxygenase 2. Therefore, the results of this study confirmed that the TID and TIE extracts have antioxidant and anti-inflammatory effects and have a high potential for use as natural materials for these purposes. © 2024 The Korean Society of Food Science and Nutrition. | Kang, Jung-Wook; Hur, Ji-Won; Yoo, Dan-Hee; Park, Mi-Kyung; Cho, Hang-Eui; Lee, In-Chul | College of Fusion and Convergence, South Korea; College of Pharmacy, Kyungpook National University, South Korea; College of Fusion and Convergence, South Korea; Creative Innovation Research Center, Cosmecca Korea Co., Ltd., South Korea; Creative Innovation Research Center, Cosmecca Korea Co., Ltd., South Korea; Department of Bio-Cosmetic Science, Seowon University, South Korea | 57678656700; 58864007800; 57189321512; 58914229400; 57678656800; 56390536600 | 5229418@hanmail.net; | Journal of the Korean Society of Food Science and Nutrition | 1226-3311 | 53 | 2 | 0 | 2025-05-07 | 0 | anti-inflammatory; antioxidant; natural material; Tillandsia ionantha | Korean | Final | 2024 | 10.3746/jkfn.2024.53.2.164 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | A Study on Driving Safety Evaluation Methods for Minimal Risk Maneuver of Automated Driving System; [자율주행시스템의 위험 최소화 기동에 대한 운행 안전성 평가 방법에 관한 연구] | This paper proposes a framework for evaluating operational safety in DDT fallback situations that may occur during autonomous driving. A safety assessment algorithm for MRM is also presented. The framework outlines the evaluation requirements for DDT fallback, scenario design, experimental methods, and analysis techniques. The safety assessment algorithm for MRM validates vehicle safety rates and proposes evaluation metrics for collision risks in both front and rear of the vehicle, based on predicted collision time and intensity. Simulations are conducted to differentiate use when stopping within the lane and stopping in a safe zone under unified DDT fallback conditions, with each MRM timing evaluated. The difference in front collision risk for stopping within the lane at various MRM timings was found to be approximately 17 %, while the rear collision safety rate was approximately 99.2 %. When stopping in a safe zone, the difference in front vehicle collision risk due to lane change attempts was approximately 65 %, with a rear collision safety rate of about 98 %. This confirms the validity of the proposed algorithm. Future research will focus on enhancing operational safety evaluation methods by establishing the criteria for assessing failures in autonomous driving systems and combinations of conditions leading to deviations from ODD.

| ○ | Article | A Study on OHCA Risk Assessment and AED Deployment Improvement in Apartment Housing for Daegu Metropolitan City; [대구시 APT OHCA 위험도 평가 및 AED 배치 개선방안 연구] | In December 2022, as the 「Emergency Medical Services Act」 was enacted to install AED (Automated External Defibrillators) with more than 500 households, it is time to analyze dangerous complexes considering the number of floors and households to improve the survival rate of high-rise residents APT (Apartment). Therefore, this study aims to suggest a system-wide improvement plan to improve the service response of OHCA (Out of Hospital Cardiac Arrest) patients by conducting a risk assessment through spatial clustering and correlation analysis reflecting the number of floors and households of APT. As a result of the study, 6.9 AED were installed per 10,000 people, 4.2 AED available 24 hours a day, and 2.9 AED available to the rest of the population except for the AED installed in APT. Based on the current status of households and floors in Daegu metropolitan city, AED vulnerability analysis of OHCA patients showed that three districts needed to re-adjust the space layout for new installation and re-installation of AED. © 2024 Korean Society of Surveying.

| ○ | Article | A Study on Performance Improvement Based on Meta-Heuristic Algorithms for Efficient Streaming Data Processing | The need to efficiently process and analyze large amounts of streaming data has led to the emergence of various stream processing platforms. However, the challenge remains to optimize several aspects of performance, such as processing speed and usage efficiency. In this study, we introduce a novel approach to address this problem using the Whale Optimization Algorithm (WOA), a metaheuristic algorithm that simulates the hunting behavior of whales. Applied to a stream processing platform, WOA achieves performance improvements compared to existing algorithms and shows parallelism and overall performance gains by tuning the executor settings of distributed computing systems such as Apache Spark where parallelism is important. We also leverage grid search, a hyperparameter optimization technique, to fine-tune the hyperparameters of WOA to achieve additional performance gains. © 2024, Korean Institute of Communications and Information Sciences.

| ○ | Article | A Study on Strategies to Activate Unused Heat Energy Based on Heat Demand in District Energy Supply Areas - Focused on Dalseo-gu, Daegu | District energy is a type of central heat energy supply system that can produce industrial process heat or heating and cooling energy for buildings. It aligns with the government's decarbonization policy by supplying energy without carbon emissions to many heat consumers, using clean hydrogen or biomass fuel for combined heat and power generation, or by utilizing unused heat energy. The purpose of this study is to explore efficient energy demand and supply systems and the acceptance of unused energy in district energy supply areas by predicting the energy supply status of a specific region and the energy demand in densely populated urban transportation hubs. The analysis method involves collecting domestic heat demand and supply data and calculating the potential of unused energy using the national heat map. Additionally, target areas are selected based on regional heat demand, and the heat supply is matched to these selected areas. To utilize unused energy, annual heating and cooling demand data, supply facility capacity, and supply status data are collected for district energy supply areas with installed heat piping networks. The study proposes strategies for accommodating unused energy in urban densely populated areas. ©2024 Architectural Institute of Korea. | Lee, Ji-Ae; Park, Yong-Seo | Convergence Institute of Construction, Environmental and Energy Engineering, Kyungpook National University, South Korea; Dept. of Architecture, Kyungpook National University, South Korea | 56165757200; 57217080207 | archipark@knu.ac.kr; | Journal of the Architectural Institute of Korea | 2733-6239 | 40 | 12 | 0 | 2025-05-07 | 0 | Collective Energy; District Heating; Incineration Heat; Recovered Waste Heat; Unused Energy; Urban High-density Area | Korean | Final | 2024 | 10.5659/jaik.2024.40.12.211 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | A Study on the Denim Textile Design Complementing the Original Bleaching Technique -Creating Tote Bags and Pouches with Traditional Korean Roof Tile Patterns-; [기존 탈색 기법을 보완한 데님 텍스타일 디자인 연구 -전통 기와 무늬를 응용한 토트백과 파우치 작품 제작을 중심으로-] | This study presents a complementary bleaching technique using laser cutting and stamping patterns on neoprene fabric to address the limitations of conventional denim bleaching methods. Neoprene was chosen for its resistance to deformation and effective bleach absorption. Through experiments, the optimal bleaching conditions were identified as a 15-minute bleaching time with 100% wet pick-up (w.p.u.) and the use of two fabric sheets simultaneously, which minimized smearing and enhanced the bleaching effect. Inspired by traditional Korean roof tile patterns, symbolizing past technological and aesthetic achievements, motifs were designed, laser cut, and applied to the fabric under these conditions. The process resulted in the creation of 13 totes and 4 pouches. This technique blends technology with craftsmanship, offering a fresh approach to textile design. Furthermore, it also has the potential to inspire the development of innovative denim textiles and cultural products, as well as to diversify creative expression, by expanding its use. © 2024, The Korean Society of Clothing and Textiles.

| ○ | Article | A Study on the Sustainability of Government R&D Subsidies | This paper investigates the sustainability of government research and development(R&D) subsidies. The main results are as follows. First, firms that receive government R&D subsidies increase sustainability. This means that firms that receive government R&D subsidies based on taxes go beyond si mply pursuing private profit and practice sustainable management through Environmental, Social and Governance and corporate social responsibility, and have a positive impact on society. Second, in the case of firms that received government R&D subsidies, the higher the sales growth rate or firm value, the more positively related to corporate sustainability compared to firms that did not receive government R&D subsidies. This means that when a firm that receives government R&D subsidies increases its performance and growth potential, its financial and economic competitiveness is satisfied, sustainability increases, and it has a positive ripple effect on society and the environment. Third, as a result of analysis by type of R&D, among firms that received government R&D subsidies, only firms in the experi mental development increase sustainability. This means that in the case of firms in the experi mental development, some of the R&D has already been achieved, or the improved results have materialized, resolving some of the uncertainty, increasing sustainability, and playing a positive role in society. While existing studies have focused on the impact of government R&D subsidies on corporate R&D invest ment, this study provides a contribution in that it confirms the positive effect of government R&D subsidies on sustainability through Environmental, Social and Governance and corporate social responsibility. © 2024, Korean Accounting Association.

| ○ | Article | A U-shaped Corridor-based Single Model Approach for Furrow Detection Throughout Agricultural Work Cycle | The automation of open-field agriculture is highly important in addressing the decline in rural populations and food security. In open-field agriculture, to prevent crop damage, the system recognizes the ridges or furrow where crops are planted and performs tasks while navigating. However, previous camera or LiDAR-based systems face the issue of needing to create or retrain models for different ridge environments altered by agricultural work. This study proposes a method that defines the morphological features of furrows and uses a single trained model, allowing it to be applied regardless of the ridge conditions altered by processes. Additionally, the method involves connecting the central points of each recognition model to create a navigation path for the robot based on furrow detection. To validate the proposed method, it was applied to two ridges with different depths under dry, wet, mulching, and sowing conditions. Consequently, the average recognition rates for the two ridges with different depths were 97.36% and 87.13%. This means that it can be applied in a variety of field farming environments. © ICROS 2024. | Kyoung, Dohyun; Kwak, Jeonghoon; Yang, Kyon-Mo; Seo, Kap-Ho | Innovation Lab-Seoul, Korea Institute of Robotics and Technology Convergence (KIRO), South Korea; Innovation Lab-Seoul, Korea Institute of Robotics and Technology Convergence (KIRO), South Korea; Innovation Lab-Seoul, Korea Institute of Robotics and Technology Convergence (KIRO), South Korea; Department of Robot and Smart System Engineering, Kyungpook National University (KNU), South Korea | 58568662800; 56963328600; 55698480000; 7201838999 | neoworld@kiro.re.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 30 | 8 | 0 | 2025-05-07 | 0 | Agricultural robot; Agricultural work cycle; Furrow detection; Ridge detection | Agricultural robots; Food security; Agricultural robot; Agricultural work cycle; Condition; Food security; Furrow detection; Ridge detections; Rural population; Single model approach; U-shaped; Work cycle; Crops | Korean | Final | 2024 | 10.5302/j.icros.2024.24.0149 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Accuracy Evaluation of Homography-Based Camera Pose and Point Depth Calculation for a Deep Learning Dataset | In recent years, large datasets have been provided for DL (Deep Learning) to train the neural network in calculating camera poses and object depths from images. The datasets were typically obtained using RGB-D (Red, Green, Blue, and Depth) cameras, however, which have limitations in capturing depths in many cases. To overcome the limitations of RGB-D cameras, many DL approaches have been proposed to overcome the problems. However, the accuracy potentials of pose and depth calculated by DL approaches have not been studied well. Thus, this study selected the ScanNet dataset for the experiment and presents a method to evaluate the accuracy of pose and depth that can be obtained using point matching and homography. From the pairs of matching points in two views, their fundamental matrix, essential matrix, and camera matrix were reconstructed and then the camera pose and depth were calculated. The experimental results show that the relative rotation angles were calculated accurately by using homography and the translation angles were calculated less accurately than the rotation angles. In addition, the experiments show that the depths of matching points could be calculated with reasonable accuracy by using the camera matrix constructed by matching. © 2024 Korean Society of Surveying.
