| ○ | ○ | Proceedings Paper | A Morphological Image-based Recognition of Iron Triad using a Convolutional Neural Network | A processed image typically results in numerous imperfections in the binary regions due to thresholding. By considering the shape and organization of the image, morphological image processing aims to overcome these shortcomings. In this research, the proposed focus is to develop a neural network model that can automatically identify and categorize elements of the Iron Triad using a Morphological Image-based Recognition through a Convolutional Neural Network (CNN). This tool extracts image components to represent and describe specific image characteristics. This paper describes the convolution-based classification neural network's architecture, which extract the critical features of the image dataset. It shows that the plot of the convolutional neural network training progress had achieved a better validation accuracy. Experiments show that the method presented is effective, providing a classification accuracy of 96.5%, which is much better than other research works that use CNN. | Raguindin, Evelyn Q.; Raguindin, Reibelle Q.; Purio, Mark Angelo C.; Juan, Ronnie O.

| ○ | ○ | Article | A Multicenter Study to Identify the Respiratory Pathogens Associated with Exacerbation of Chronic Obstructive Pulmonary Disease in Korea | Background: Although respiratory tract infection is one of the most important factors triggering acute exacerbation of chronic obstructive pulmonary disease (AE-COPD), limited data are available to suggest an epidemiologic pattern of microbiology in South Korea. Methods: A multicenter observational study was conducted between January 2015 and December 2018 across 28 hospitals in South Korea. Adult patients with moderate-to-severe acute exacerbations of COPD were eligible to participate in the present study. The participants underwent all conventional tests to identify etiology of microbial pathogenesis. The primary outcome was the percentage of different microbiological pathogens causing AE-COPD. A comparative microbiological analysis of the patients with overlapping asthma-COPD (ACO) and pure COPD was performed. Results: We included 1,186 patients with AE-COPD. Patients with pure COPD constituted 87.9% and those with ACO accounted for 12.1%. Nearly half of the patients used an inhaled corticosteroid-containing regimen and one-fifth used systemic corticosteroids. Respiratory pathogens were found in 55.3% of all such patients. Bacteria and viruses were detected in 33% and 33.2%, respectively. Bacterial and viral coinfections were found in 10.9%. The most frequently detected bacteria were Pseudomonas aeruginosa (9.8%), and the most frequently detected virus was influenza A (10.4%). Multiple bacterial infections were more likely to appear in ACO than in pure COPD (8.3% vs. 3.6%, p=0.016). Conclusion: Distinct microbiological patterns were identified in patients with moderate-to-severe AE-COPD in South Korea These findings may improve evidence-based management of patients with AE-COPD and represent the basis for further studies investigating infectious pathogens in patients with COPD. | Lee, Hyun Woo;

| ○ | ○ | Proceedings Paper | A New nalysis Method Based on Lumped Magnetic Circuit Model for Surface Permanent-Magnet Machines with Step-Skewed Rotor | This study proposes a new analysis method based on lumped magnetic-circuit for surface permanent-magnet machine (SPM) with overhang and step-skewed rotor. In SPM machine, the step-skew lowers the torque pulsation and makes the electromotive force sinusoidal, and the overhang structure increases the torque density. A time-consuming three dimensional (3-D) finite element method (FEM) is required to analyze axial components such as step-skew leakage flux and overhang flux. To deal with this problem, a new equivalent lumped magnetic-circuit model for each rotor step considering the axial leakage flux between the steps and the linkage flux by the overhang is introduced. The validity of the proposed method is verified by comparing a two-dimensional and 3-D FEM of skewed, non-skewed, overhang, and non- overhang SPMs. | Kim, Rae-Eun; Hahn, Seungyong; Seo, Jangho | Seoul Natl Univ, Seoul, South Korea; Korea Elect Technol Inst, Bucheon, South Korea; Seoul Natl Univ, Dept Elect & Comp Engn, Seoul, South Korea; Kyungpook Natl Univ, Sch Automot Engn, Sangju, South Korea | 57189235125; 7401984639; 12791073600 | kre2567@keti.re.kr;syhahn@snu.ac.kr;j.seo@knu.ac.kr; | TWENTIETH BIENNIAL IEEE CONFERENCE ON ELECTROMAGNETIC FIELD COMPUTATION (IEEE CEFC 2022) | 0 | 2025-06-25 | 0 | 0 | 3-D finite element method; step-skew; overhang; surface permanent magnet machines | COGGING TORQUE | 3-D finite element method; overhang; step-skew; surface permanent magnet machines | Circuit simulation; Electric machinery; Finite element method; Flux linkage; Lumped parameter networks; Magnetic leakage; Permanent magnets; Timing circuits; 3D Finite Element Method (FEM); Analysis method; Leakage flux; Lumped magnetic circuits; Magnetic circuit model; Overhang; Skewed rotors; Step skews; Surface permanent magnet machines; Torque pulsation; Magnetic circuits | English | 2022 | 2022 | 10.1109/cefc55061.2022.9940697 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||

| ○ | ○ | Proceedings Paper | A Novel Processing Unit and Architecture for Process-In Memory (PIM) in NAND Flash Memory | Process-in Memory (PIM) is a scheme to enhance the processing speed in artificial intelligence (AI) by reducing the data bottle neck that occurs between the processor and memory. Typical PIM schemes focus on developing optimal paths between CPU and SRAM/DRAM. However, SRAM/DRAM based PIM may not be the optimal solution for cases where the data size for processing can easily be beyond the capacity of SRAM/DRAM. Thus, we propose a PIM scheme for NAND flash memory that shares the cache register. Our scheme significantly reduces the data transfer inside the memory hierarchy and reduces the runtime by -41.6% compared to DRAM PIM scheme. Compared to NAND flash scheme, we reduce the runtime by -34.6% | Kim, HyunWoo; Baek, Seungwon; Song, Jaehong; Kim, Junhyeon; Jung, Minyoung; Kim, Hyodong; Kim, Seongju; Song, Taigon | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 59862730600; 58108885200; 58109032900; 36005021000 | hyun753951@knu.ac.kr;tsong@knu.ac.kr; | 2022 19TH INTERNATIONAL SOC DESIGN CONFERENCE (ISOCC) | 2163-9612 | 0.8 | 2025-06-25 | 3 | 3 | NAND Flash; Processing-in Memory; Local core | Local core; NAND Flash; Processing-in Memory | Bottles; Cache memory; Data transfer; Flash memory; Memory architecture; NAND circuits; Static random access storage; Local core; Memory schemes; NAND Flash; NAND flash memory; Novel processing unit; Processing architectures; Processing speed; Processing-in-memory; Runtimes; SRAM/DRAM; Dynamic random access storage | English | 2022 | 2022 | 10.1109/isocc56007.2022.10031375 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Proceedings Paper | A Novel Technique For Indoor Object Distance Measurement By Using 3D Point Cloud and LiDAR | The SLAM (Simultaneous Localization and Mapping) technology has been widely exploited to collect information of location and environment for indoor mobile robots. Usually, SLAM has a single LiDAR(Light Detection and Ranging) sensor which reveals its vulnerability to complex terrain or distinction between objects. A possible solution to overcome this problem is the data fusion technique with LiDAR and depth cameras. This paper presents a novel data fusion technique with LiDAR data and 3D-point cloud data for estimating the surrounding object locations. In the proposed technique, the surrounding object location data are extracted using the region-based segmentation technique in real time using 3D-point cloud images. The effectiveness of the proposed algorithm is demonstrated with a set of experiments based on ROS (Robot Operating System). | Kim, Jisoo; Lee, Dongik | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea | jisha@naver.com;dilee@ee.knu.ac.kr; | 2022 22ND INTERNATIONAL CONFERENCE ON CONTROL, AUTOMATION AND SYSTEMS (ICCAS 2022) | 2093-7121 | 1 | region-based segmentation; 3D point cloud; indoor mobile robot; LiDAR; ROS | REGION-BASED SEGMENTATION | English | 2022 | 2022 | 바로가기 | ||||||||||||||||||||||

| ○ | Article | A Path Planning Algorithm for AUV Using Fuzzy Logic and Artificial Potential Field | An autonomous underwater vehicle (AUV) must move from a start point to a target point without colliding with other vehicles or obstacles to execute various missions. Path planning is a crucial function that causes AUVs to find the shortest and safest path without human intervention. This paper presents a path planning algorithm that adopts a safety distance to keep the vehicle as safe as possible while avoiding collisions with obstacles. The algorithm uses a combination of fuzzy logic (FL) and an artificial potential field (APF), which together overcome the shortcomings of global path planning. The proposed algorithm simultaneously considers the shortest path to the target position while maintaining a safe distance from obstacles. The effectiveness of the proposed algorithm is demonstrated with computer simulations.

| ○ | ○ | Article | A pooled Bayes test of independence using restricted pooling model for contingency tables from small areas | For a chi-squared test, which is a statistical method used to test the independence of a contingency table of two factors, the expected frequency of each cell must be greater than 5. The percentage of cells with an expected frequency below 5 must be less than 20% of all cells. However, there are many cases in which the regional expected frequency is below 5 in general small area studies. Even in large-scale surveys, it is difficult to forecast the expected frequency to be greater than 5 when there is small area estimation with subgroup analysis. Another statistical method to test independence is to use the Bayes factor, but since there is a high ratio of data dependency due to the nature of the Bayesian approach, the low expected frequency tends to decrease the precision of the test results. To overcome these limitations, we will borrow information from areas with similar characteristics and pool the data statistically to propose a pooled Bayes test of independence in target areas. Jo et al. (2021) suggested hierarchical Bayesian pooling models for small area estimation of categorical data, and we will introduce the pooled Bayes factors calculated by expanding their restricted pooling model. We applied the pooled Bayes factors using bone mineral density and body mass index data from the Third National Health and Nutrition Examination Survey conducted in the United States and compared them with chi-squared tests often used in tests of independence. | Jo, Aejeong; Kim, Dal Ho | Natl Evidence based Healthcare Collaborating Agcy, Div Res & Dev, Seoul, South Korea; Kyungpook Natl Univ, Dept Stat, Daegu, South Korea; Kyungpook Natl Univ, Dept Stat, 80 Daehakro, Deagu 41566, South Korea | 59814059300; 57198636658 | dalkim@knu.ac.kr; | COMMUNICATIONS FOR STATISTICAL APPLICATIONS AND METHODS | COMMUN STAT APPL MET | 2287-7843 | 2383-4757 | 29 | 5 | ESCI | STATISTICS & PROBABILITY | 2022 | 0.4 | 0 | 2025-06-25 | 0 | 0 | pooled Bayes factor; nonparametric hierarchical Bayesian model; Dirichlet process; slice sampling; small area | SPECIFICATIONS; METHODOLOGY | Dirichlet process; Nonparametric hierarchical bayesian model; Pooled bayes factor; Slice sampling; Small area | English | 2022 | 2022-09 | 10.29220/csam.2022.29.5.547 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | A Possible Relation of Pacific Decadal Oscillation with Weakened Tropical Cyclone Activity over South Korea | Although tropical cyclones with wind speeds weaker than 17 m s(-1) (weak tropical cyclones: WTCs) can cause significant damage, particularly over the Seoul metropolitan area, only a few studies have focused on WTC activity over South Korea. In this study, we found that WTC activity is likely associated with the Pacific Decadal Oscillation (PDO). During the negative phases of the PDO, landfall frequency of WTCs increased significantly compared to the positive phases at 95% confidence level. When related to the negative phases of the PDO, a positive relative vorticity anomaly is found in the northern sector of the western North Pacific while a negative relative vorticity anomaly and enhanced vertical wind shear prevail in the southern sector of the WNP. These factors are favorable for the northward shift of the genesis location of tropical cyclones on average, thereby reducing the total lifetime of WTCs. Moreover, a high-pressure anomaly over the Japanese islands would shift a tropical cyclone track westward in addition to the landfall location. Consequently, the effects of the topographical friction and the Yellow Sea Bottom Cold Water on a tropical cyclone may increase. These conditions could result in a weaker lifetime maximum intensity and landfall intensity, ultimately resulting in WTCs becoming more frequent over South Korea during the negative phases of the PDO. | Chang, Minhee; Park, Doo-Sun R.; Kim, Dasol; Park, Tae-Won | Seoul Natl Univ, Sch Earth & Environm Sci, Seoul 08826, South Korea; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu 41566, South Korea; Univ Florida, Dept Geog, Gainesville, FL 32611 USA; Chonnam Natl Univ, Dept Earth Sci Educ, Gwangju 61186, South Korea | Park, Doo-Sun/U-9448-2019; Kim, Dasol/GWR-1499-2022; Park, Tae-Won/AAE-3559-2019 | dsrpark@knu.ac.kr; | JOURNAL OF THE KOREAN EARTH SCIENCE SOCIETY | J KOR EARTH SCI SOC | 1225-6692 | 2287-4518 | 43 | 1 | ESCI | GEOSCIENCES, MULTIDISCIPLINARY | 2022 | 0.4 | 1 | Tropical cyclone; Typhoon; Pacific Decadal Oscillation; South Korea | ENSO | Korean | 2022 | 2022-02 | 10.5467/jkess.2022.43.1.23 | 바로가기 | 바로가기 | 바로가기 | ||||||||||

In this paper, we show a prototype implementation of a full-software 3D rasterizer system, based on the CUDA parallel architecture. While most of previous CUDA-based software rasterizer implementations focused on the triangle primitives, our system includes more 3D primitives, and extra 2D primitives, to fully support 3D graphics library features. Currently, our system is at its prototype implementation stage, and it shows successful results with 3D primitive handling and also character output features.

| ○ | ○ | Article | A randomized, open-label, single- dose, two-way crossover study to assess the pharmacokinetics between two tablets of fixed-dose combination formulation with raloxifene and cholecalciferol and concomitant administration of each agents in healthy male volunteers | A new fixed-dose combination (FDC) formulation of raloxifene 60 mg and cholecalciferol 800 IU was developed to improve the medication compliance and overall efficacy of raloxifene treatment in postmenopausal osteoporosis patients. The aim of this study was to compare the pharmacokinetics between two tablets of FDC formulation of raloxifene/cholecalciferol and the two products administered concomitantly at respective doses. This randomized, open-label, single-dose, two-treatment, two-way crossover study included 46 volunteers. During each treatment period, subjects received the test formulation (FDC formulation containing raloxifene and cholecalciferol) or the reference formulation (co-administration of raloxifene and cholecalciferol), with a 14-d washout period. Serial blood samples were collected periodically over 96 hours after drug intake. In total, 46 subjects completed the study. The geometric mean ratios and its 90% confidence intervals of the FDC to the single agents for the area under the concentration-time curve from zero to the last quantifiable time point and the maximum plasma concentration met the regulatory criteria for bioequivalence: 1.1364 (1.0584- 1.2201) and 1.1010 (0.9945-1.2188) for raloxifene and 1.0266 (0.9591-1.0989) and 1.0354 (0.9816-1.0921) for baseline-corrected cholecalciferol, respectively. Both formulations were well tolerated. No significant differences was observed in the incidence of adverse events between the two treatments. It was concluded that two tablets of the newly developed FDC formulation of raloxifene and cholecalciferol and the corresponding two agents administered concomitantly at respective doses were bioequivalent. | Lee, Hae Won; Kang, Woo Youl; Gwon, Mi-Ri; Choi, Eun Jung; Kim, Eun Hee; Cho, Kyunghee; Lee, Bakhwan; Seong, Sook Jin; Yoon, Young-Ran | Kyungpook Natl Univ Hosp, Dept Clin Pharmacol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Clin Om Inst, Sch Med, Daegu 41944, South Korea; Daegu Catholic Univ, Coll Nursing, Gyongsan 38430, South Korea; Biocore Co Ltd, Analyt Res Div, Seoul 08511, South Korea; Alvogen Korea Co Ltd, Dept Clin Dev, Seoul 07326, South Korea; Kyungpook Natl Univ, Sch Med, Dept Mol Med, 130 Dongdeok ro, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Clin Pharmacol, 130 Dongduk ro, Daegu 41944, South Korea | Yoon, Young-Ran/GLT-0172-2022 | 57202973823; 56816263900; 56035800800; 59036869800; 57203519526; 57211130109; 57192838300; 57211130049; 14629744500 | wintersj@knu.ac.kr;yry@knu.ac.kr; | TRANSLATIONAL AND CLINICAL PHARMACOLOGY | TRANSL CLIN PHARMACO | 2289-0882 | 2383-5427 | 30 | 3 | ESCI | PHARMACOLOGY & PHARMACY | 2022 | 0.9 | 0.31 | 2025-06-25 | 2 | 2 | Osteoporosis; Pharmacokinetics; Raloxifene; Cholecalciferol | POSTMENOPAUSAL WOMEN; BONE TURNOVER; OSTEOPOROSIS; BIOAVAILABILITY; MARKERS | Cholecalciferol; Osteoporosis; Pharmacokinetics; Raloxifene | alanine aminotransferase; aspartate aminotransferase; bilirubin; calcium; colecalciferol; colecalciferol derivative; creatinine; dp r213; raloxifene; sunscreen; vitamin D; accuracy; adult; apparent elimination half life; area under the concentration time curve; area under the curve; area under the infinity; area under the last measurement; Article; bioanalytical method; bioequivalence; blood analysis; blood-to-plasma ratio; body weight; calibration; centrifugation; clinical evaluation; coefficient of variation; compartmental analysis; controlled study; creatinine clearance; crossover procedure; demography; drug efficacy; drug formulation; drug megadose; drug tolerability; electrocardiography; female; geometric mean; human; human experiment; hypercalcemia; hypercalciuria; hypocalcemia; incidence; limit of quantitation; liquid liquid extraction; male; mass spectrometry; maximum plasma concentration; middle aged; normal human; open label study; patient compliance; phase 1 clinical trial; postmenopause osteoporosis; protein precipitation; randomized controlled trial; sample size; sequence analysis; single drug dose; solid phase extraction; sun exposure; tandem mass spectrometry; ultra fast liquid chromatography; vitamin supplementation; young adult | English | 2022 | 2022-09 | 10.12793/tcp.2022.30.e13 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Proceedings Paper | A Region Descriptive Pre-training Approach with Self-attention Towards Visual Question Answering | Concatenation of text (question-answer) and image has been the bedrock of most visual language systems. Existing models concatenate the text (question-answer) and image inputs in a forced manner. In this paper, we introduce a region descriptive pre-training approach with self-attention towards VQA. The model is a new learning method that uses the image region descriptions combined with object labels to create a proper alignment between the text(question-answer) and the image inputs. We study the text associated with each image and discover that extracting the region descriptions from the image and using it during training greatly improves the model's performance. In this research work, we use the region description extracted from the images as a bridge to map the text and image inputs. The addition of region description makes our model perform better against some recent state-of-the-art models. Experiments demonstrated in this paper show that our model significantly outperforms most of these models. | Kolawole, Bisi Bode; Lee, Minho | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu, South Korea; Kyungpook Natl Univ, Grad Sch Artificial Intelligence, 80 Daehak Ro, Daegu, South Korea | NEURAL INFORMATION PROCESSING, ICONIP 2021, PT VI | 1865-0929 | 1865-0937 | 1517 | 0 | Visual question answering; Region descriptions; Object label; Pre-training | English | 2022 | 2022 | 10.1007/978-3-030-92310-5_9 | 바로가기 | 바로가기 | ||||||||||||||||||||
| ○ | ○ | Proceedings Paper | A Reinforcement Learning-based Path Planning for Collaborative UAVs | Unmanned Aerial Vehicles (UAVs) are widely used in search and rescue missions for unknown environments, where maximized coverage for unknown devices is required. This paper considers using collaborative UAVs (Col-UAV) to execute such tasks. It proposes to plan efficient trajectories for multiple UAVs to collaboratively maximize the number of devices to cover within minimized flying time. The proposed reinforcement learning (RL)-based Col-UAV scheme lets all UAVs share their traveling information by maintaining a common Q-table, which reduces the overall time and the memory complexities. We simulate the proposed RL Col-UAV scheme under various simulation environments with different grid sizes and compare the performance with other baselines. The simulation results show that the RL ColUAVs scheme can find the optimal number of UAVs required to deploy for the diverse simulation environment and outperforms its counterparts in finding a maximum number of devices in a minimum time. | Rahim, Shahnila; Razaq, Mian Muaz; Chang, Shih Yu; Peng, Limei | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; San Jose Univ, Dept Appl Data Sci, San Jose, CA USA | Rahim, Shahnila/LRC-2927-2024; Razaq, Muaz/ACN-8991-2022 | 57416456600; 57221661906; 57221159388; 7201574271 | shahnila.rahim@knu.ac.kr;mianmuaz97@gmail.com;shihyu.chang@sjsu.edu;auroraplm@knu.ac.kr; | 37TH ANNUAL ACM SYMPOSIUM ON APPLIED COMPUTING | 1.16 | 2025-06-25 | 8 | 13 | Reinforcement learning; Unmanned Aerial Vehicle (UAV); Path Planning; Collaborative UAVs | collaborative UAVs; path planning; reinforcement learning; unmanned aerial vehicle (UAV) | Antennas; Motion planning; Reinforcement learning; Collaborative unmanned aerial vehicle; Flying time; Grid size; Memory complexity; Rescue missions; Search and rescue; Search missions; Simulation environment; Unknown environments; Unmanned aerial vehicle; Unmanned aerial vehicles (UAV) | English | 2022 | 2022 | 10.1145/3477314.3507052 | 바로가기 | 바로가기 | 바로가기 |
