| ○ | Conference paper | Dynamic MAC Unit Pruning Techniques in Runtime RTL Simulation for Area-Accuracy Efficient Implementation of Neural Network Accelerator | Designing lightweight hardware accelerators that maintain model inference accuracy is a challenging task in edge artificial intelligence (AI) because of the heterogeneous design requirements between the software model and hardware accelerator. While model pruning is an effective approach for reducing the number of parameters and computational requirements, conventional software model pruning leads to inefficient overhead when deploying the model in a general-purpose accelerator for inference. To overcome these challenges, we propose an empirical register transfer level (RTL) simulation-based accelerator pruning technique that is optimized for domain applications and models. Specifically, the proposed technique measures the dynamic switching of processing element (PE) unit-wise signals during dataset sample inference on a 2D array of PEs and replaces it with dummy PEs based on the RTL simulation results. The proposed approach reduces the accelerator's area and power resource consumption while maintaining baseline accuracy. We automated the RTL generation and simulation reconfiguration process to enable PE pruning that requires iterative and empirical RTL simulation based on signal switching count results. Our experimental results show that while the model's inference accuracy decreased by only 1% (98% to 97%), we were able to reduce dynamic signal switching and synthesized area by up to 9.78% and 4.25%, respectively. Our approach suggests a lightweight hardware accelerator design that is dedicated to the target application and can be scaled without modifying the model. © 2023 IEEE. | Kwon, Jisu; Yun, Heuijee; Park, Daejin | School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University, Daegu, 41566, South Korea | 57215531728; 57222516795; 55463943600 | boltanut@knu.ac.kr; | Midwest Symposium on Circuits and Systems | 1548-3746 | 0 | 2025-06-25 | 0 | Efficient implementation; Hardware accelerators; Model inference; Model pruning; Neural-networks; Processing elements; Pruning techniques; Register-transfer level; Runtimes; Software modeling; Iterative methods | English | Final | 2023 | 10.1109/mwscas57524.2023.10406146 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Conference paper | Dynamic Selection Scheme of LTE-M and 5G for Efficient Maritime Communication Based on Traffic Volume | This paper investigates the technology for selecting communication scheme based on the amount of traffic in LTE-M (Marine) and 5G communication environments. Recently, it has been possible to use LTE-M and 5G communications for preventing collisions between ships and obstacles in coastal areas, moving from a focus on terrestrial users. This paper proposes a scheme for efficiently handling both small-scale and large-volume traffic generated from terminals on ships. LTE-M can accommodate more terminals by utilizing the wide coverage of coastal areas, but it can be vulnerable to high-volume video processing for real-time obstacle detection. 5G provides a high data transmission rate and low latency, making it suitable for large data exchanges between ships or real-time services, but its short coverage makes it unsuitable for accommodating a wide area. Therefore, this paper proposes a scheme for dynamically selecting LTE-M or 5G communication schemes according to the amount of data generated by terminals on ships, to transmit data. In this paper, we propose an algorithm to decide which communication scheme, LTE-M or 5G, should be chosen based on the amount and type of traffic. The algorithm dynamically selects the optimal communication scheme considering real-time traffic information and network status. By implementing a simulation environment for coastal areas using the technique proposed in this paper, we compare the scheme where terminals installed on ships selectively use LTE-M and 5G communication schemes with the scheme where two communication schemes are chosen randomly for transmission. The simulation results confirm that the proposed technique can process more data compared to the existing schemes.

| ○ | ○ | Proceedings Paper | ECM: An Energy-efficient HVAC Control Framework for Stable Construction Environment | A cargo containment system (CCS) of liquefied natural gas (LNG) is an essential component of an LNG carrier (LNGC). During the manufacturing process of the LNGC CCS, it is critical that the heating, ventilation, and air conditioning (HVAC) facility stabilizes the environmental states inside the CCS at all times to prevent devastating rust and dew from forming inside the LNGC CCS. One critical problem is that it consumes enormous power, resulting in high expenses. To alleviate this problem, we propose our design of a novel data-driven framework, termed ECM, that uses a combination of machine learning and deep reinforcement learning (DRL) models to robustly and automatically control the HVAC system. Based on selected features, we develop the best indoor-environment forecasting model from several candidate models and build an HVAC control agent by training the DRL model with the reward function that uses the predicted temperature and humidity through the forecasting model. To validate our proposed framework, we have assessed the performance of our models on the real-world sensor data obtained from one of the major world-class shipyards. As a result, we show that our DRL-based model trained in the proposed framework stably controls the temperature inside the CCS within only 1.5 degrees C variance in the set range from 23 degrees C to 25 degrees C while on average consuming power up to about 34% less than the compared existing methods. We expect our framework will bring an annual savings of about $14 million or more once deployed in the actual field. | Ok, Jin-Sung; Chae, Youngeun; Seo, Harin; Kwon, Soon-Do; Tak, Byungchul; Suh, Young-Kyoon | Hanwha Ocean, Digital Solut R&D Ctr, Geoje, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | 55586710100; 58703589400; 58703741700; 57223428660; 6506911621; 55443739900 | jsok@hanwha.com;yechae@knu.ac.kr;rinyo0126@knu.ac.kr;inno33@hanwha.com;bctak@knu.ac.kr;yksuh@knu.ac.kr; | 2023 20TH ANNUAL IEEE INTERNATIONAL CONFERENCE ON SENSING, COMMUNICATION, AND NETWORKING, SECON | 2473-0440 | 0 | 2025-06-25 | 0 | 0 | Machine Learning; Time-Series Forecasting; Reinforcement Learning; HVAC; LNGC CCS | MANAGEMENT | HVAC; LNGC CCS; Machine Learning; Reinforcement Learning; Time-Series Forecasting | Deep learning; Energy efficiency; Forecasting; Humidity control; HVAC; Liquefied natural gas; Ships; Air conditioning controls; Cargo containment systems; Forecasting models; Heating ventilation and air conditioning; LNG carrier cargo containment system; LNG carriers; Machine-learning; Reinforcement learning models; Reinforcement learnings; Time series forecasting; Reinforcement learning | English | 2023 | 2023 | 10.1109/secon58729.2023.10287528 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Eco-friendly biosynthesis metallic silver nanoparticles using Aegle marmelos (Indian bael) and its clinical and environmental applications | The current research aims to examine the biological synthesis of silver nanoparticles (AgNPs) by Aegle marmelos aqueous leaf extract (Am). The structure, composition and the size of the AgNPs identified by X-ray crystallography (XRD), scanning electron microscopy (SEM), zetapotential, atomic force microscopy (AFM), energy dispersive X-ray diffraction (EDAX), Fourier transfer infrared spectroscopy (FT-IR) and Ultraviolet–Visible (UV–vis) absorption spectroscopy. UV-spectrum confirmed the formation of AgNPs at 416 nm range. The antimicrobial activity was performed against Bacillus megaterium (B. megaterium), Bacillus aryabhattai (B. aryabhattai), Staphylococcus aureus (S. aureus), Serratia marcescens (S. marcescens), and Pseudomonas putida (P. putida) by well diffusion assay, the highest zone formation was observed (8.4 ± 0.3) in 100 µg/mL concentration of Am-AgNPs against Serratia marcescens. The larvicidal assay was performed against Culex quinquefasciatus (C. quinquefasciatus) and Aedes aegypti (A. aegypti). The higher efficiency of Am-AgNPs immersed in A. aegypti (LC50 = 302.02 ppm) and C. quinquefasciatus (LC50 = 132.01 ppm). Further, methylene blue (MB) photocatalytic activity was studied by dye degradation method under visible light irradiation treatment, in the visible region by increasing the time; and light absorption and the enhancement of photocatalytic degradation was observed. Besides, anticancer activity against gastric cancer cells was studied, which showed (IC50) value 40.33 µg/mL. These results conclude that synthesized Am-AgNPs act as a novel antibacterial, anticancer, larvicidal, and photocatalytic agent. © 2021, King Abdulaziz City for Science and Technology. | Sampath, Gattu; Govarthanan, Muthusamy; Rameshkumar, Neelamegam; Vo, Dai-Viet N.; Krishnan, Muthukalingan; Sivasankar, Palaniappan; Kayalvizhi, Nagarajan | Department of Zoology, School of Life Sciences, Periyar University, Tamil Nadu, Salem, 636 011, India; Department of Environmental Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Life Sciences, Central University of Tamil Nadu, Tamil Nadu, Thiruvarur, 610005, India; Center of Excellence for Green Energy and Environmental Nanomaterials (CE@GrEEN), Nguyen Tat Thanh University, 300A Nguyen Tat Thanh, District 4, Ho Chi Minh City, 755414, Viet Nam; Madurai Kamaraj University, Tamil Nadu, Madurai, 625 021, India; Department of Environmental Science, School of Life Sciences, Periyar University, Tamil Nadu, Salem, 636 011, India; Department of Zoology, School of Life Sciences, Periyar University, Tamil Nadu, Salem, 636 011, India | 57216919716; 54881927600; 35173727100; 35957358000; 7102069651; 57204715313; 15740927000 | kayalvizhinagarajan@gmail.com; | Applied Nanoscience (Switzerland) | 2190-5509 | 13 | 1 | 5.25 | 2025-06-25 | 45 | AGS cells; Antimicrobial; Larvicidal; Photocatalytic activities; Silver nanoparticles | Absorption spectroscopy; Aromatic compounds; Bacteria; Bacteriology; Biochemistry; Diseases; Infrared spectroscopy; Light; Light absorption; Metal nanoparticles; Photocatalytic activity; Scanning electron microscopy; Silver compounds; Synthesis (chemical); Ultraviolet spectroscopy; X ray crystallography; Aedes aegypti; Aegle marmelos; AGS cells; Antimicrobial; Culex quinquefasciatus; Eco-friendly; Larvicidal; Metallic silver; Photocatalytic activities; Serratia marcescens; Silver nanoparticles | English | Final | 2023 | 10.1007/s13204-021-01883-8 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Ecophysiological characteristics of Rosa rugosa under different environmental factors | Background: Ecophysiological characteristics of Rosa rugosa were analyzed under different environmental factors from May to October 2022. Photosynthesis, chlorophyll fluo-rescence, chlorophyll content, leaf water content (LWC), osmolality, carbohydrate content, and total ion content were measured to compare the physiological characteristics of R. rugosa at two study sites (i.e., in large pots and in the Goraebul coastal sand dune area). Results: When R. rugosa was exposed to high temperatures, photosynthetic parameters including net photosynthetic rate (PN) and stomatal conductance (gs) in both experiment areas declined. In addition, severe photoinhibition occurs when R. rugosa is continuously exposed to high photosynthetically active radiation (PAR), and because of this, relatively low Y(II) (i.e., the quantum yield of photochemical energy conversion in photosystem II [PSII]) and high Y(NO) (i.e., the quantum yield of non-regulated, non-photochemical energy loss in PSII) in the R. rugosa of the pot were observed. As the high Y(NPQ) (i.e., the quantum yield of regulated non-photochemical energy loss in PSII) of R. rugosa in the coastal sand dune, they dissipated the excessed photon energy through the non-photochemical quenching (NPQ) mechanism when they were exposed to relatively low PAR and low tem-perature. Rosa rugosa in the coastal sand dune has higher chlorophyll a and carotenoid content. The high chlorophyll a + b and low chlorophyll a/b ratios seemed to optimize light absorption in response to low PAR. High carotenoid content played an important role in NPQ. As a part of the osmotic regulation in response to low LWCs, R. rugosa exposed to high temperatures and continuously high PAR used soluble carbohydrates and ions to maintain high osmolality. Conclusions: We found that Fv/Fm was lower in the potted plants than in the coastal sand dune plants, indicating the vulnerability of R. rugosa to high temperatures and PAR levels. We expect that the suitable habitat range for R. rugosa will shrink and move to north under climate change conditions. © 2023 The Author(s) Open Access. | Kim, Young-Been; Yim, Sung-Hwan; Sim, Young-Seok; Choo, Yeon-Sik | Department of Integrative Natural Sciences for the East Sea Rim, Kyungpook National University, Daegu, 41566, South Korea, Seed Vault Center, Baekdudaegan National Arboretum, Bonghwa, 36209, South Korea; Department of Biology, Kyungpook National University, Daegu, 41566, South Korea, Research Institute for Dok-do Ulleung-do Island, Kyungpook National University, Daegu, 41566, South Korea; Department of Biology, Kyungpook National University, Daegu, 41566, South Korea; Department of Integrative Natural Sciences for the East Sea Rim, Kyungpook National University, Daegu, 41566, South Korea, Department of Biology, Kyungpook National University, Daegu, 41566, South Korea, Research Institute for Dok-do Ulleung-do Island, Kyungpook National University, Daegu, 41566, South Korea | 58562757700; 57219408645; 57219400815; 26040458100 | yschoo@knu.ac.kr; | Journal of Ecology and Environment | 2288-1220 | 47 | 0.2 | 2025-06-25 | 1 | climate change; coastal sand dune; environmental change; photosynthesis; Rosa rugosa | English | Final | 2023 | 10.5141/jee.23.040 | 바로가기 | 바로가기 | |||||||||||||||||

| ○ | Article | Effect of Gd3+/Nd3+- dual doped borate glasses on the physical and spectroscopic properties for the NIR emission at 1.069 µm | Near-infrared luminescence properties of dual doped Gd3+/Nd3+-incorporated glasses were manufactured using the melt-quenching technique and characterized by several techniques. The modification in glass structure may be seen in the differences in density, molar volume, and refractive index that occur when the amount of lanthanide oxide in the glass increases. The spectroscopic properties of Nd3+ in these glasses are quite well understood, and the observed optical characteristics may be used to process and eventually determine laser properties. According to the results of XANES, the Nd oxidation state remains the predominant peak for Nd3+ in all of the samples. The transition from 4I9/2 to 4G5/2 +2G7/2 is important for the strongest band in the absorption spectra, which can be seen at 584 nm. The luminescence spectra show peaks caused by 4F3/2→4IJ (J=11/2, 13/2) at three excitation wavelengths of 526, 574 and 805 nm. After the processing, we created glass samples for the study of photoluminescence with various amounts of Nd2O3 incorporated into the best host, 25Li2O-5Al2O3-2.5Gd2O3-(67.5-X)B2O3-XNd2O3. Based on luminescence intensity, it is determined that 1.0 mol% of Nd2O3 is the concentration quenching in the studied glasses. The 4F3/2 →4I11/2 transition at 1069 nm, excited by 526, 578 and 803 nm, has the highest emission intensity. The combined findings of the glasses demonstrate that near-infrared luminescence may be successfully used with them. All of the analysis shows that the dual doped Gd3+/Nd3+ borate glass would be a potential solid-state laser candidate. © 2023 Elsevier GmbH | Manyum, P.; Rittisut, W.; Mool-am-kha, P.; Wantana, N.; Ruangtaweep, Y.; Rujirawat, S.; Yimnirun, R.; Kidkhunthod, P.; Prasatkhetragarn, A.; Kothan, S.; Kim, H.J.; Minh, P.H.; Kaewkhao, J. | School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasima, 30000, Thailand; School of Physics and Center of Excellence in High Energy Physics and Astrophysics, Suranaree University of Technology, Nakhon Ratchasima, 30000, Thailand; Construction Materials Group, Engineering Materials Division, Department of Science Service, Ministry of Higher Education, Science, Research and Innovation, Bangkok, 10400, Thailand; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand; Synchrotron Light Research Institute (Public Organization), 111 University Avenue, Muang, Nakhon Ratchasima, 30000, Thailand; School of Energy Science and Engineering, Vidyasirimedhi Institute of Science and Technology (VISTEC), Rayong, Wangchan, 21210, Thailand, Research Network of NANOTEC-VISTEC on Nanotechnology for Energy, Vidyasirimedhi Institute of Science and TECHNOLOGY (VISTEC), Rayong, Wangchan, 21210, Thailand; Synchrotron Light Research Institute (Public Organization), 111 University Avenue, Muang, Nakhon Ratchasima, 30000, Thailand; Applied Science Program, School of Science, University of Phayao, Phayao, 56000, Thailand; Center of Radiation Research and Medical Imaging, Department of Radiologic Technology, Faculty of Associated Medical Sciences, Chiang Mai University, Chiang Mai, 50200, Thailand; Department of Physics, Kyungpook National University, Daegu, 41566, South Korea; Institute of Physics, Vietnam Academy of Science and Technology, 10 Dao Tan, Ba Dinh, Hanoi, Viet Nam; Physics Program, Faculty of Science and Technology, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand, Center of Excellence in Glass Technology and Materials Science, Nakhon Pathom Rajabhat University, Nakhon Pathom, 73000, Thailand | 6506891657; 57208675448; 57223232295; 56267058700; 37108588700; 6603107856; 24504594000; 35272197100; 23098474100; 6507017165; 59051568100; 23973373800; 23974520300 | pmanyum@sut.ac.th;jakrapong@webmail.npru.ac.th; | Optik | 0030-4026 | 290 | 0.13 | 2025-06-25 | 1 | Dual doped Gd<sup>3+</sup>/Nd<sup>3+</sup>; Melt-quenching technique; Near-infrared luminescence | Alumina; Aluminum oxide; Gadolinium compounds; Glass; Infrared devices; Lithium compounds; Quenching; Refractive index; Solid state lasers; Borate glass; Dual doped; Dual doped gd3+/nd3+; Glass structure; Lanthanide oxide; Luminescence properties; Melt quenching techniques; Near infrared luminescence; NIR emission; Spectroscopic property; Neodymium compounds | English | Final | 2023 | 10.1016/j.ijleo.2023.171246 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Effect of intense pulsed light (IPL) on sterilization of Bacillus cereus and spores in fresh-cut vegetables | Due to various factors, the use of fresh vegetables is increasing; however, several studies associate this food group with most food poisoning. In addition, as the vegetables are consumed raw, sterilization methods other than heating are essential. Therefore, the objective of this study is to evaluate the effect of intense pulsed light (IPL) on the sterilization of a major food-borne pathogen Bacillus cereus and its spores, in fresh-cut vegetables such as carrots, cabbage, and onions. The color changes after the treatment were also observed. The results showed that the inactivation of Bacillus cereus and spores increased with the increase in the voltage and duration of the IPL treatment. The inactivation of spores was lower than that of the vegetative cells, and it became less efficient as the spore concentration increased. The color was retained without significant changes. These results indicate that IPL treatment can effectively inactivate the pathogens in fresh-cut vegetables without altering their color. © 2023 Korean Society of Food Science and Technology.

| ○ | Article | Effect of Lignin-Rich Microfiber on Handsheet Strength | This study explores the effects of using lignin-rich microfibers as a reinforcing material to enhance paper strength. The microfibers prepared by alkaline kneading of organosolv pulp for 1 to 3 hours were characterized in terms of fiber dimensions, residual lignin content, freeness, and water retention value. Longer alkaline kneading times were more effective for improved fiber micronization. In addition, freeness decreased and water retention value increased as a result of the kneading treatment. The microfibers were added at increasing amounts (1%, 3%, and 5% based on oven-dry weight) to commercial bleached kraft pulp to evaluate the effect of microfiber content on handsheet strength. The results showed that microfibers at a level of 5% increased the tensile index of the handsheet by up to 8%, indicating that lignin-rich microfibers have a high potential for use as paper strength additives. © 2023 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | ○ | Proceedings Paper | Effect of Loading Frequency on the Liquefaction Resistance of Poorly Graded Sand | Cyclic simple shear tests were carried out to study the effect of frequency (f) on the poorly graded sand's liquefaction resistance. The samples are prepared in the medium state (D-r = 60%) by the deposition method, and a wide range of f (f = 0.03, 0.05, 0.1, 0.2, and 0.5 Hz) is considered. The results show that the liquefaction resistance is uninfluenced by low f (0.03 and 0.05 Hz). When the f is higher than the optimum frequency (f(opt) = 0.1 Hz), the liquefaction resistance increases with increasing f. | Park, Sung-Sik; Tran, Dong-Kiem-Lam; Nguyen, Tan-No; Woo, Seung-Wook; Sung, Hee-Young | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | ; Tran, Dong-Kiem-Lam/KLY-3827-2024 | 36241850300; 57217738208; 57862912800; 57212917862; 58161037600 | sungpark@knu.ac.kr;lam.trandongkiem@uah.edu.vn;nonguyen@knu.ac.kr;geowsw@knu.ac.kr;bryanfriend@naver.com; | ADVANCES IN GEOSPATIAL TECHNOLOGY IN MINING AND EARTH SCIENCES | 1863-5520 | 1863-5539 | 3.11 | 2025-06-25 | 3 | 3 | Cyclic simple shear test; Liquefaction resistance; Loading frequency; Poorly graded sand | Cyclic simple shear test; Liquefaction resistance; Loading frequency; Poorly graded sand | Liquefaction; Cyclic simple shear; Cyclic simple shear test; Deposition methods; Graded sand; Liquefaction resistance; Loading frequencies; Optimum frequency; Poorly graded sand; Resistance increase; Simple shear test; Shear flow | English | 2023 | 2023 | 10.1007/978-3-031-20463-0_6 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Book chapter | Effect of Mineral Nutrition and PGRs on Biosynthesis and Distribution of Secondary Plant Metabolites under Abiotic Stress | Secondary plant metabolites are necessary for the survival of plants and help to establish interactions between plants and environment. They constitute an important part of the plant’s defense mechanism against pathogenic attacks and environmental stresses, in addition to providing a valuable range of natural products. Plants being sessile in nature safeguard themselves from severe conditions around them by means of bioactive compounds produced as secondary metabolites. These metabolites serve as a deterrent to herbivores, provide a barrier against pathogen invasion, and reduce oxidative stress during stressful situations. The accumulation of these metabolites increases under environmental stress, such as soil water, minerals, temperature, salinity, light, humidity, air pollutants, heavy metals and frost, among others. Changes in the nutritional and hormonal status regulate the secondary metabolites production in plants. This article examines how the mineral nutrient elements and plant hormones influence the accumulation of secondary metabolites in plants under abiotic stress conditions. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023. | Jan, Rahmatullah; Lubna; Asaf, Sajjad; Khan, Muhammad Aaqil; Kim, Kyung-Min | Division of Plant Biosciences, Department of Applied Biosciences, College of Agriculture and Life Science, Kyungpook National University, Daegu, South Korea; Department of Botany, Garden Campus, Abdul Wali Khan University, Mardan, Pakistan; Natural and Medical Sciences Research Center, University of Nizwa, Nizwa, Oman; Division of Plant Biosciences, Department of Applied Biosciences, College of Agriculture and Life Science, Kyungpook National University, Daegu, South Korea; Division of Plant Biosciences, Department of Applied Biosciences, College of Agriculture and Life Science, Kyungpook National University, Daegu, South Korea | 57201981969; 57200621537; 56595059900; 57188585606; 34868260300 | kkm@knu.ac.kr; | Medicinal Plants: Their Response to Abiotic Stress | 5.33 | 2025-06-25 | 3 | Abiotic stress; Elicitors; Metabolites; Plant defense; Plant hormones | English | Final | 2023 | 10.1007/978-981-19-5611-9_11 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | Effect of Multidisciplinary Program for Relapse Prevention on Abstinence Self-efficacy, Impulsivity and Suicidal Ideation among Patients with Substance Use Disorder | Purpose: The purpose of this study was to examine the effects of a multidisciplinary program for relapse prevention on abstinence self-efficacy, impulsivity and suicidal ideation among patients with substance use disorder Methods: A nonequivalent control group non-synchronized design was used. The participants were 42 substance addicted patients admitted to the addiction ward. The study variables of abstinence self-efficacy, impulsivity, and suicidal ideation were evaluated by the x2 test, Kolmogorov-Smirnov test, Shapiro-Wilk test, Mann-Whitney U test using the SPSS program. Results: The experimental group showed a significant difference in abstinence self-efficacy (U=54.50, p<.001), impulsivity (U=88.00, p<.001) and suicidal ideation (U=77.50, p<.001) compare to the control group. Conclusion: The multidisciplinary relapse prevention program was effective in improving abstinence self-efficacy, impulsivity, and suicidal ideation. It is essential to develop optimal nursing interventions for patients with substance use disorders to prevent relapse. © 2023 The Korean Academy of Psychiatric and Mental Health Nursing. | Soyun, An; Wanju, Park | Bugok National Hospital, Changnyeong, South Korea; College of Nursing, Research Institute of Nursing Science, Kyungpook National University, Daegu, South Korea | 58481108400; 35788492900 | wanjupark@knu.ac.kr; | Journal of Korean Academy of Psychiatric and Mental Health Nursing | 1225-8482 | 32 | 2 | 0 | 2025-06-25 | 0 | Impulsive behavior; Self efficacy; Substance-related disorders; Suicide | Korean | Final | 2023 | 10.12934/jkpmhn.2023.32.2.216 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Effect of Optimization Techniques on Feedback Alignment Learning of Neural Networks | The error backpropagation algorithm is a representative learning method that has been used in most deep network models. However, the error backpropagation algorithm, despite its decent performance, clearly has limits to its biological plausibility. Unlike the learning mechanism of the actual brain, the error backpropagation algorithm must reuse the weights used in the forward calculation for the backward error propagation. In order to overcome these limitations, the feedback alignment method, which uses a fixed random weight for the backpropagation computation, was proposed. The feedback alignment algorithm showed performances comparable to the original error backpropagation on several benchmark data sets. However, it is still in the preliminary stage of analysis, and various analysis on its learning behavior and practical efficiency are needed. In this paper, we combine feedback alignment learning method with popular optimization techniques such as RMSprop and Adam, and investigate its effect on the learning performances through computational experiments on benchmark data sets. | Lee, Soha; Park, Hyeyoung | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | 58175908900; 55713613500 | kiyo91012@gmail.com;hypark@knu.ac.kr; | 2023 INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE IN INFORMATION AND COMMUNICATION, ICAIIC | 2831-6991 | 0 | 2025-06-25 | 0 | 0 | Error backpropagation; Biological plausibility; Feedback alignment; Weight transport problem; Random backward weight; Optimization algorithm | DYNAMICS | Biological plausibility; Error backpropagation; Feedback alignment; Optimization algorithm; Random backward weight; Weight transport problem | Backpropagation; Bioinformatics; Learning systems; Biological plausibility; Error back-propagation; Error backpropagation algorithms; Feedback alignment; Learning methods; Optimization algorithms; Optimization techniques; Random backward weight; Transport problems; Weight transport problem; Errors | English | 2023 | 2023 | 10.1109/icaiic57133.2023.10067047 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Effect of Plant Essential Oil Formulations on Bemisia tabaci MEAM1 (Gennadius) and Its Parasitoid Eretmocerus hayati (Zolnerowich and Rose) | Silverleaf whitefly (SLW), Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), consists of genetically diverse species known to cause significant destruction in many crops around the world. Nowadays, synthetic insecticides are a key component in the management of this pest. However, they also come with disadvantages, such as environmental pollution, pest resistance and recurrence, and toxicity to pollinators and natural enemies. Essential oils from aromatic plants and biocontrol agents may provide a new and safe alternative to synthetic chemicals. In this study, we assessed the lethal impact of three new plant essential oil formulations (referred to as F1, F2, and F3) against the developmental stages of B. tabaci and its parasitoid Eretmocerus hayati (Zolnerowich and Rose) (Hymenoptera: Aphelinidae). The tested formulations consisted of combinations of mustard oil and different surfactants. The formulations were effective against the eggs and nymphal stages of B. tabaci. At the highest concentration assessed (1.23%), F1 was the most effective formulation against the eggs, resulting in 85% mortality, whereas F2 was most effective against the nymphs (92.5% and 88.3% mortality for the young and old nymphs, respectively). However, adult mortality rates were below 40% for all the tested formulations. The range of median lethal concentration (LC50) values was between 0.65 and 1.05% for B. tabaci. The side effects of the three formulations were assessed against E. hayati, treated as parasitized nymphs of B. tabaci. At the highest tested concentration (1.23%), F2 and F3 resulted in 80% and 70% mortality of the parasitoids, respectively (classified as moderately or slightly harmful according to the IOBC), whereas F1 resulted in 17.5% mortality. As F1 was effective against SLW with minimal effects on the parasitoid, it is the most suitable formulation of those tested for use in an integrated pest management (IPM) program targeting the younger life stages of B. tabaci. | Hassan, Errol; Obaidoon, Yasir; Mostafiz, Md Munir; Senior, Lara | Univ Queensland, Sch Agr & Food Sci, St Lucia, Qld 4072, Australia; Kyungpook Natl Univ, Agr Sci & Technol Res Inst, Daegu 41566, South Korea; Ecosci Precinct, Dept Agr & Fisheries, Dutton Pk, Qld 4102, Australia | Mostafiz, Md.

| ○ | Article | Effect of structural variation of medium chain fatty acids on antibacterial activities against pathogenic bacteria | Broad range of fatty acids were reported to show antimicrobial activities against broad range of microorganisms. However, possible changes of the antibacterial activity of a fatty acid based on structural variations are largely unknown. This study was focused on determination and comparison of the antimicrobial activities of the medium chain fatty acids, based on the position of carboxyl groups on either terminal end, against the representative food-pathogenic bacteria. Over all, mono-carboxyl medium chain fatty acids (MC-MCFA) presented stronger antimicrobial activities against the food-pathogenic bacteria tested including methicillin-resistant Staphylococcus aureus (MRSA) than di-carboxyl medium chain fatty acid (DC-MCFA). In addition, some of MC-MCFA and DC-MCFA showed high possibility to be used as a synergistic adjuvant for both the commercial β-lactam family antibiotics and aminoglycoside family antibiotics against MRSA. © The Korean Society for Applied Biological Chemistry 2023. | Choi, Ju-Hyeon; Son, Su-Hyeon; Kim, Hak-Ryul | School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea | 58196314200; 59271491500; 57191717289 | hakrkim@knu.ac.kr; | Journal of Applied Biological Chemistry | 1976-0442 | 66 | 1 | 0 | 2025-06-25 | 0 | Antimicrobial activity; Di-carboxyl medium chain fatty acid; Methicillin-resistant Staphylococcus aureus; Monocarboxyl medium chain fatty acid; Synergistic adjuvant | Korean | Final | 2023 | 10.3839/jabc.2023.011 | 바로가기 | 바로가기 |
