| ○ | ○ | Proceedings Paper | A Haar Classifier Accelerator with Reduced Multiplexer Usage | A Haar classifier accelerator is widely used in embedded vision systems because it can detect faces rapidly and accurately. However, implementing the Haar classifier accelerator requires considerable hardware resources, many of which are multiplexers used to extract integral values within a sub-window. Therefore, to decrease the multiplexer usage in the Haar classifier accelerator, we propose a method that reduces the sub-window size by excluding some rows and columns of the sub-window from integral value extraction. The proposed method considerably reduces the multiplexer usage than that of the conventional method while maintaining the detection rate and the number of false detections. | Lee, SangHyun; Moon, Byungin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Moon, Byungin/ACE-5308-2022 | 57423689200; 55419717700 | dycjd2001@knu.ac.kr;bihmoon@knu.ac.kr; | 18TH INTERNATIONAL SOC DESIGN CONFERENCE 2021 (ISOCC 2021) | 2163-9612 | 0 | 2025-07-30 | 0 | 0 | face detection; Haar classifier accelerator; FPGA | face detection; FPGA; Haar classifier accelerator | Embedded systems; Field programmable gate arrays (FPGA); Multiplexing equipment; Conventional methods; Detection rates; Embedded visions; Faces detection; Haar classifier accelerator; Haar classifiers; Hardware resources; Integral values; Vision systems; Window Size; Face recognition | English | 2021 | 2021 | 10.1109/isocc53507.2021.9613971 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | A Hangul Sebeolsik(3-Layer) 23-Keys Phoneme/Syllable Chorded Keys Computer Keyboard for Easy Fingering: Ahnmatae Keyboard Improvement | For high speed key in, it must be entered in syllable units like the shorthand method. In this study, fingering was made easier by reducing the number of keys on the existing Ahnmatae keyboard, which is a syllable unit input method, from 30 to 23 and adjusting the key arrangement for each phoneme. That is, the Ahnmatae keyboard was improved. Hangul's 8 initial consonant keys, 8 neutral vowel keys, and 7 final consonant keys were placed. It was designed with 23 single-key phonemes and 44 two-keys combination phoneme chorded key phonemes. The number of keys to be pressed at the same time to key in a single syllable, that is, the number of syllable chorded keys is 2 to 6. Existing was 2 to 8. The key input weight effort index obtained by applying the phoneme use frequency was 1.60ue(unit effort). Existing was 1.92ue. The entropy value of the phoneme use frequency was 1.46nat. The weight effort index to entropy ratio obtained from this entropy value and the weight effort index value was 1.10ue/nat. Existing was 1.32ue/nat. The actual operation was implemented by setting the Nalgaeset which is a keyboard design software, and using the N key roll-over keyboard. © 2021, Korean Institute of Communications and Information Sciences.

| ○ | ○ | Proceedings Paper | A Hybrid Discrete Differential Evolution Approach for the Single Machine Total Stepwise Tardiness Problem with Release Dates | In this paper, a novel hybrid discrete differential evolution based approach is proposed to address a single machine scheduling problem where each job has a release date and the tardiness cost of the job increases stepwise with respect to various due dates. In the literature, this problem is termed as the single machine total stepwise tardiness problem with release dates (SMTSTP-R). The objective of the problem is to find a schedule of jobs which minimizes the total tardiness cost. The stepwise increase in tardiness cost is more prevalent in several real life scenario, especially in transportation. We have used two constructive heuristics and concept of opposition based solutions to generate initial population. Our proposed approach uses a series of local searches to further enhance the quality of solutions obtained by the proposed discrete differential evolution approach. In order to justify the superiority of proposed approach, various comparisons are done with the existing approaches available in the literature. The results of these comparisons validate the superiority of our approach in comparison to the existing state-of-the-art approaches. | Srivastava, Gaurav; Singh, Alok; Mallipeddi, Rammohan | Univ Hyderabad, Sch Comp & Informat Sci, Hyderabad 500046, India; Kyungpook Natl Univ, Sch Elect Engn, Dept AI, Daegu 41566, South Korea | ; Srivastava, Dr. Gaurav/LBH-5030-2024; Mallipeddi, Rammohan/AAL-5306-2020 | 56597524700; 35254330000; 25639919900 | gauravsrignp@gmail.com;alokcs@uohyd.ernet.in;mallipeddi.ram@gmail.com; | 2021 IEEE CONGRESS ON EVOLUTIONARY COMPUTATION (CEC 2021) | 1.28 | 2025-07-30 | 4 | 4 | Discrete differential evolution; Discrete optimization; Scheduling; Single machine total stepwise tardiness problem with release dates | N-JOB; ALGORITHM | Discrete differential evolution; Discrete optimization; Scheduling; Single machine total stepwise tardiness problem with release dates | Evolutionary algorithms; Job shop scheduling; Discrete differential evolutions; Discrete optimization; Due dates; Evolution-based approach; Release date; Single machine scheduling problems; Single machine total stepwise tardiness problem with release date; Single- machines; Tardiness cost; Total tardiness; Scheduling algorithms | English | 2021 | 2021 | 10.1109/cec45853.2021.9504914 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | A Low-Complexity Symbol Detection Scheme for LoRa Signals | For the widespread use of Internet of Things (IoT) devices, a low-power low-cost implementation is important for the IoT communications. In order to achieve this goal, in this letter, we consider the problem of symbol detection for LoRa, which is one of the most widely-used low power wide area (LPWA) technologies for IoT. Especially for achieving long battery life and low implementation cost for IoT devices, a low complexity symbol detection algorithm is proposed for the LoRa modulated signals. In order to evaluate the performance of the proposed scheme, compared to the conventional fast Fourier transform (FFT) based symbol detection, we show that the proposed scheme effectively reduces the computational complexity while achieving the optimal performance for symbol detection. © 2021, Korean Institute of Communications and Information Sciences.

| ○ | Article | A Lower Bound on the Capacity of MIMO Channels with One-Bit ADCs | One-bit ADC has been studied as a useful solution to resolve inherent problems in massive multiple-input and multiple-output (MIMO) systems and mmWave communications in 5G and beyond 5G standards. However, the capacity of a MIMO channel using one-bit ADCs is not known in an explicit form. As an alternative, upper and lower bounds have been derived in the literature. In this study, we consider a zero-forcing-based algorithm to provide a closer lower bound for the capacity of a MIMO channel with one-bit ADCs. © 2021, Korean Institute of Communications and Information Sciences.

| ○ | Article | A Meta Analysis of Impulsivity Related to Self-destructive Behavior in Korean Adolescents | Purpose: The purpose of this study is to determine the results of a meta-analysis of impulsivity variables related to self-destructive behavior of South Korean adolescents. Methods: A meta-analysis was carried out according to the Cochrane guidelines criteria and the quality of the studies was evaluated using the JBI checklist. 2,333 studies were collected through the databases of RISS, KISS, and DBpia on ‘impulsivity’ published from 2000 to 2020. Self-destructive behavior-related variables were largely categorized into three areas (addiction, violence, and delinquency), and six subgroups. Results: Using the correlations with impulsivity in the final 53 papers, 231 self-destructive behavior-related variables were identified. The social delinquency showed the closest relationship with impulsivity (ES=0.34, 95% CI: 0.23~0.43, p<.001), followed by addictive behavior (ES=0.28, 95% CI: 0.24~0.32, p<.001), personal delinquency (ES=0.28, 95% CI: 0.23~0.32, p<.001), violence against others, violence against self, and substance addiction. These effects were identified as ranging from magnitudes of 0.23 to 0.27 based on the criteria of Cohen. Conclusion: To improve the reliability of the results of meta-analysis, more studies on the impulsivity of adolescents should be carried out so that the results can be accumulated, and the effectiveness can be examined in-depth later. © 2021 Korean Academy of Community Health Nursing | Wanju, Park; Shinjeong, Park; Moonji, Choi; Kyengjin, Kim | College of Nursing, Kyungpook National University, Daegu, South Korea; College of Nursing, Kyungpook National University, Daegu, South Korea; Department of Nursing, Kyungil University, Gyeongsan, South Korea; Department of Nursing, Kyungil University, Gyeongsan, South Korea | 35788492900; 57347984800; 57347829400; 57226488036 | kkj0908@kiu.kr; | Journal of Korean Academy of Community Health Nursing | 1225-9594 | 32 | 3 | 0 | 2025-07-30 | 0 | Adolescent; Impulsive behavior; Meta-analysis; Self-destructive behavior | English | Final | 2021 | 10.12799/jkachn.2021.32.3.325 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | A method of counting vehicle with high accuracy using YOLO v3 | A method for counting the running and queuing vehicles through installed traffic surveillance cameras at intersections has been studied for a long time. Recent research via deep learning has shown many breakthroughs with high performance results that were not achieved with traditional machine learning algorithms. In the field of object detection, these algorithms have shown high accuracy in real traffic environments, but have relatively low accuracy concerning small vehicles over a long distance, the number of which is required in counting queuing vehicles. In this paper, we are proposing a method to improve detection performance by optimizing the size of the CNN network and the size of the input image by using an open source-based, deep learning framework, YOLO, to increase the detection accuracy of small vehicles over a long distance. This study aims to improve the accuracy of vehicle counting by as much as 4.6 % over the existing method.

| ○ | Article | A method of measuring wood failure percentage of wood specimens bonded with melamine-urea-formaldehyde resins using image analysis | Transparent and colorless melamine-urea-formaldehyde (MUF) resins make it difficult to identify the area of wood failure percentage (WFP) in the fracture surface of bonded wood specimens. Therefore, in this study, we develop a method of measuring WFP after the adhesion strength measurement of MUF resins under shear stress. The fractured wood surface of block shear strength (BSS) specimens bonded with cold-setting MUF resins at three melamine contents (20%, 30%, and 40%) was marked black, and then, WFP was accurately measured via image analysis. WFP values measured using this method consistently increased with BSS as the melamine content increased, showing the reliability of this new method. The results suggested that this new method is useful and reliable for measuring the WFP of the fracture surface of wood specimens bonded with colorless adhesives such as urea-formaldehyde, MUF, and melamine-formaldehyde resins. © 2021, Korean Society of Wood Science Technology.

| ○ | ○ | Proceedings Paper | A Multi-scale Capsule Network for Improving Diagnostic Generalizability in Breast Cancer Diagnosis Using Ultrasonography | Recently, deep learning has shown promising results in medical image processing. However, computer-aided diagnosis (CAD) systems based on deep learning still struggle for the real-world deployment, due to its low generalizability and reliability. It is essential to improve the generalization performance to enable them to be used routinely in clinical practice. In this paper, we propose a capsule network with a multi-scale setting to achieve better generalization performance in the differential diagnosis of breast tumors using ultrasonography. The proposed network utilizes a Gaussian pyramid to learn multi-scale features of breast tumors and dynamic routing to improve its robustness against image quality with severe noises. To evaluate the generalizability of the proposed method, we collected breast ultrasound images from 4 different hospitals and used one dataset from 1 hospital as a train set and the rest as external validation sets. We compared the classification performance with other networks, which were employed for the ultrasound diagnosis in previous studies, on the external validation sets. We also conducted additional experiments: feature space visualization and robustness evaluation study with respect to the image noise. Our model showed better classification results than other networks, such as GoogLeNet and Inception-v3, in the external validation. Experimental results also indicate that the proposed network can learn more robust and noise-invariant features from breast ultrasound imaging. | Kim, Chanho; Kim, Won Hwa; Kim, Hye Jung; Kim, Jaeil | Kyungpook Natl Univ, 80 Daehak ro, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, 807 Hoguk ro, Daegu, South Korea | 57216946967; 59443634400; 57203506201; 57211615348 | threeyears@gmail.com; | PREDICTIVE INTELLIGENCE IN MEDICINE, PRIME 2021 | 0302-9743 | 1611-3349 | 12928 | 0.27 | 2025-07-30 | 1 | 1 | Computer-aided diagnosis; Capsule network; Generalizability; Breast cancer; Ultrasonography | Breast cancer; Capsule network; Computer-aided diagnosis; Generalizability; Ultrasonography | Computer aided analysis; Computer aided instruction; Deep learning; Diseases; Hospitals; Image enhancement; Medical imaging; Tumors; Ultrasonography; Breast Cancer; Breast cancer diagnosis; Breast tumour; Capsule network; Generalizability; Generalization performance; Learn+; Medical images processing; Multi-scales; Validation sets; Computer aided diagnosis | English | 2021 | 2021 | 10.1007/978-3-030-87602-9_17 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | Conference paper | A novel reversal method for measurement of rotary manipulator geometric errors | We develop a novel method to measure six geometric errors (two position-independent geometric errors and four position-dependent geometric errors) of a rotary manipulator; we use two displacement sensors and one measurement target to this end. To enhance measurement accuracy, the method initially removes setup errors that distort the sensor data and then models the geometric errors using an nth-order polynomial equation exhibiting C1-continuity. The data are used to define the relative positions of the reference and measurement co-ordinate systems using a homogeneous transform matrix. The geometric errors of a rotary manipulator are measured using the least squares method to exploit the linear relationship between the errors and the measurement target profile. We validate our method via simulation and assess measuring uncertainties with consideration of measurement noise. © 2021 ACM. | Lee, Jae-Chang; Lee, Kwang-Il; Kim, Chang-Hwan; Yang, Seung-Han | Yeungnam University College, 170 Hyeonchng-ro, Nam-gu, Daegu, South Korea; Kyungil University, 50, Gamasil-gil, Hayang-eup, Gyeongsan-si, Gyeongbuk, South Korea; Yeungnam University College, 170 Hyeonchng-ro, Nam-gu, Daegu, South Korea; Kyungpook National University, 1370, Sangyeok-dong, Daegu, South Korea | 55260415200; 57196250383; 57305396600; 8407949900 | ACM International Conference Proceeding Series | 0 | 2025-07-30 | 0 | geometric error; parametric modeling; reversal method; rotary manipulator | Errors; Geometry; Least squares approximations; Polynomials; Uncertainty analysis; Displacement sensor; Geometric errors; Measurement accuracy; Measurements of; Novel methods; Parametric models; Position dependents; Reversal methods; Rotary manipulator; Setup errors; Manipulators | English | Final | 2021 | 10.1145/3471985.3472370 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | A Numerical Study for Meniscus Vortices Induced by Mold Flow Instabilities | The vortex core has a very strong intensity for entraining the gas in the rotating center by angular momentum conservation. Particularly, slag can be entrained into the molten steel when the meniscus vortex occurs in the mold process of the continuous casting. The entrained slag can cause serious surface defects, such as the scab and blister, in the produced steel products. The meniscus vortex accompanies a large deformation of free surface, such as vortex dimples or vortex cores. However, the free surface deformation has not been considered in the earlier studies for the meniscus vortex. We numerically investigated the meniscus vortex in the mold using a multiphase model based on a laminar model. Therefore, the proposed model successfully reproduced the important physics such as the meniscus instability, transient behavior of recirculation roll cells, biased flow, and meniscus vortex. | Pak, Seong Bae; Lee, Jong Hui; Park, Il Seouk | Kyungpook Natl Univ, Dept Mech Engn, Daegu, South Korea | Lee, Jong Hui/JFT-0292-2023 | einstein@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS B | T KOR SOC MEC ENG B | 1226-4881 | 45 | 9 | ESCI | ENGINEERING, MECHANICAL | 2021 | N/A | 0 | Meniscus Deformation; Vortex Core; Flow Asymmetry; Recirculation Roll Cell | CONTINUOUS-CASTING MOLD; STEEL/SLAG INTERFACE; CORE PHENOMENON; WATER-MODEL; FIELD; VORTEX; TANK | Korean | 2021 | 2021-09 | 10.3795/ksme-b.2021.45.9.479 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | A Perspective on the Impact of COVID-19 Pandemic on Basic Science Research and its Future Implications | COVID-19 has emerged as a devastating pandemic of the century that the current genera-tions have ever experienced. The COVID-19 pandemic has infected more than 12 million people around the globe, and 0.5 million people have succumbed to death. Due to the lack of effective vaccines against the COVID-19, several nations throughout the globe have imposed a lock-down as a preventive measure to lower the spread of COVID-19 infection. As a result of lock-down, most of the universities and research institutes have witnessed a long pause in basic science research ever. Much has been discussed about the long-term impact of COVID-19 on the economy, tourism, public health, small and large-scale businesses of several kinds. However, the long-term effects of the shut-down of these research labs and their impact on basic science research has not been much focused. Herein, we provide a perspective that portrays a common problem of all the basic science researchers throughout the globe and its long-term consequences. © 2021 Bentham Science Publishers. | Paudel, Yam Nath; Angelopoulou, Efthalia; Giri, Bhupendra Raj; Piperi, Christina; Oth-Man, Iekhsan; Shaikh, Mohd.

| ○ | Article | A Phenomenological Study on the Lived Experiences of Patients Recovered from COVID-19 | Purpose: This descriptive phenomenological study explored the lived experiences of patients recovering from Coronavirus Disease-2019 (COVID-19). Methods: Using a purposive sampling method, participants were recruited from the Korean Psychological Association’s Mental Health and Wellness Center in G city, South Korea, from May 5 to December 30, 2020. The interviews were analyzed using Colaizzi’s seven-step method. Data saturation was reached after interviewing 14 participants. Results: The experiences of patients recovering from COVID-19 were clustered into 4 main themes and 10 subthemes:, namely, the patients’ 1) stigmatization, leading to anxiety, fatigue, and concern about neighbors; 2) negative emotions: anger and helplessness; 3) coping strategies under pressure: increased gratitude, self-reflection, and self-efficacy; and 4) ways of overcoming internalized stigma: personal growth and hope for the future. Discussion: The results suggest that the positive and negative emotions of patients recovering from COVID-19 are interwoven and coexist against the background of the pandemic. Improvement of social networks, development of coping skills, and psychological growth play an important role in alleviating the psychological burden of recovering patients. © 2021 Korean Society of Adult Nursing.

| ○ | Conference paper | A Practical Implementation of the Ternary Logic Using Memristors and MOSFETs | Due to the impotent forecasts of binary systems, ternary systems are regaining attention. Among many ternary devices, a passive device called memristor that is based on resistance switching is considered a good candidate when integrated with MOSFETs. Therefore, in this paper, we design ternary logic based on memristors and MOSFETs. We highlight the design issues that should be resolved (e.g., signal distortion and high static current) and present practical solutions. To the best of the authors' knowledge, we present 15 novel ternary logic cells and circuitry that include the design of the first balanced ternary full adder (TFA). By our TFA, we visualize that it is possible to design the most practical ternary circuits using memristors and MOSFETs. Our TFA uses 97 transistors and 87 memristors, which is the most reasonable TFA design that has the highest potential to be implemented in the near future. © 2021 IEEE. | Yang, Jeonggyu; Lee, Hyundong; Jeong, Jae Hoon; Kim, Tae Hak; Lee, Sin-Hyung; Song, Taigon | School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronics Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea | 57221952581; 57226892881; 57226881576; 57225038681; 57226880204; 36005021000 | Proceedings of The International Symposium on Multiple-Valued Logic | 0195-623X | 2021-May | 4.56 | 2025-07-30 | 13 | memristor; ternary full-adder; ternary logic | Logic devices; Many valued logics; Memristors; MOSFET devices; Binary systems; Design issues; On-resistance; Passive devices; Practical solutions; Static currents; Ternary circuits; Ternary logic; Computer circuits | English | Final | 2021 | 10.1109/ismvl51352.2021.00039 | 바로가기 | 바로가기 |
