| ○ | Article | Development of a system to retrieve manufacturing conditions to support 3D printing-based part maintenance | In order to maintain parts critical to using 3D printing technology, it is necessary to provide the user with information about powders, equipment, processing conditions, and inspection methods, as well as 3D CAD models used as input files for 3D printing operations. In order to address this issue, this paper proposes a manufacturing condition retrieval system that provides the information necessary for the maintenance of parts important to using 3D printing technology. To accomplish this, we define a data structure that stores manufacturing condition information for 3D printers. Then, after analyzing the user's requirements, we design the manufacturing condition retrieval system. Finally, we implement a prototype system, construct a database using sample manufacturing condition sheets, and perform data retrieval experiments.

| ○ | ○ | Article | Development of an Efficient Method to Evaluate the Optimal Location of Groundwater Dam | In this study, a data-driven response surface method using the results acquired from the numerical simulation is developed to evaluate the potential storage capacity of groundwater due to the construction of a groundwater dam. The hydraulic conductivities of alluvium and basement rock, depth and slope of the channel are considered as the natural conditions of the location for groundwater dam construction. In particular, the probability models of the hydraulic conductivities and the various types of geometry of the channel are considered to ensure the reliability of the numerical simulation and the generality of the developed estimation model. As the results of multiple simulations, it can be seen that the hydraulic conductivity of basement rock and the depth of the channel greatly influence to the groundwater storage capacity. In contrast, the slope of the channel along the groundwater flow direction shows a relatively lower impact on the storage capacity. Based on the considered natural conditions and the corresponding numerical simulation results, the storage capacity estimation model is developed applying an artificial neural network as the nonlinear regression model for training. The developed estimation model shows a high correlation coefficient (>0.9) between the simulated and the estimated storage amount. This result indicates the superiority of the developed model in evaluating the storage capacity of the potential location for groundwater dam construction without the numerical simulation. Therefore, a more objective and efficient comparison for the storage capacity between the different potential locations can be possibly made based on the developed estimation model. In line with this, the proposed method can be an effective tool to assess the optimal location of groundwater dam construction across Korea. | Jeong, Jina; Park, Eungyu | Kyungpook Natl Univ, Dept Geol, Daegu, South Korea | 55488558800; 23995577700 | egpark@knu.ac.kr; | ECONOMIC AND ENVIRONMENTAL GEOLOGY | ECON ENVIRON GEOL | 1225-7281 | 2288-7962 | 53 | 3 | ESCI | GEOLOGY | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | groundwater dam; optimal location; groundwater flow numerical simulation; response surface method; artificial neural network | Artificial neural network; Groundwater dam; Groundwater flow numerical simulation; Optimal location; Response surface method | Korean | 2020 | 2020-06 | 10.9719/eeg.2020.53.3.245 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Development of an image processing-based ball tracking program for table tennis | [Purpose] The purpose of this study was to develop algorithms and software that can track the trajectory of table tennis balls using image-processing algorithms to obtain information quickly for under and establish tactics used in table tennis. [Methods] The algorithms used in the field of computer vision were applied on two matches played by novice and two matches during international competitions by elite athletes. Reliability analysis was performed by comparing the table tennis ball bounce frequency in each zone obtained through the automatic method and the manual method. [Results] The mean reliability of the two novice games was only 85.1 ± 3.69%, total error was 14.9 ± 3.69%, overestimation error was 52.2 ± 9.78%, and underestimation error was 47.8 ± 9.78%. While the mean reliability of the two international tournaments was 71.8 ± 0.87%, the total error was 28.2 ± 0.87%, overestimation error was 82.0 ± 8.03%, and underestimation error was 19.2 ± 7.75%. [Conclusion] Although the target reliability of algorithms and software developed in this study was achieved only in novice competitions with 80%, the over-estimation errors were generally high in international competitions, showing the potential for further improvement. © Korea Institute of Sport Science. | Moon, Je-Heon; Lee, Seung-Hun; Lee, Ju-Sung; Manish, Panday; Sanchez, Gustavo Adrian Ruiz; Panday, Siddhartha Bikram | Korea Institute of Sport Science, South Korea; Dankook University, South Korea; Kangwon National University, South Korea; Kyungpook National University, South Korea; Keimyung University, South Korea; Keimyung University, South Korea | 55659623500; 58569570400; 56011569700; 58569144000; 57224318113; 56010835400 | sid@kmu.ac.kr; | Korean Journal of Sport Science | 1598-2920 | 31 | 2 | 0.12 | 2025-06-25 | 1 | Computer Vision; Image Processing; Table Tennis Ball Tracking; Tournament Analysis | Korean | Final | 2020 | 10.24985/kjss.2020.31.2.180 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Development of Anti-windup Techniques for Cascade Control System | In this research, the anti-windup techniques for the cascade control system are newly developed. Cascade control system has an additional internal feedback control loop to reject disturbances better than the conventional control system. Remarkable difference between the conventional single-loop control system and the cascade control system is the interaction that the controller output saturation of the secondary control loop strongly affects the integral action of the primary control loop. In industry, local back calculation anti-windup method has been mainly used for each controller without considering the interaction between the two controllers. But it cannot eliminate the integral-windup of the primary controller originated from the saturation of the secondary controller output. To solve the problem, the two anti-windup techniques of the cascade conditional integration and the cascade back calculation are proposed in this research by extending the local anti-windup techniques for the single-loop control system to the cascade control system. Simulation confirmed that the proposed methods can effectively remove the integral windup of the primary controller caused by the saturation of the secondary controller output and show good control performances for various types of processes and controllers. If the reliability of the proposed methods is proved through the applications to real processes in the future, they would highly contribute to improving the control performances of the cascade control system in industry. | Bae, Jeong Eun; Kim, Kyeong Hoon; Chu, Syng Chul; Heo, Jaepil; Lim, Sanghun; Sung, Su Whan | Kyungpook Natl Univ, Sch Appl Chem Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57218849373; 57195755639; 57218852891; 57217335552; 57218849821; 7202731867 | suwhansung@knu.ac.kr; | KOREAN CHEMICAL ENGINEERING RESEARCH | KOREAN CHEM ENG RES | 0304-128X | 2233-9558 | 58 | 3 | ESCI | ENGINEERING, CHEMICAL | 2020 | N/A | 0.07 | 2025-06-25 | 1 | 1 | PID; Anti-windup; Cascade Control System; Conditional Integration; Back Calculation | RELAY; FRAMEWORK | Anti-windup; Back Calculation; Cascade Control System; Conditional Integration; PID | Korean | 2020 | 2020-06 | 10.9713/kcer.2020.58.3.430 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | Article | Development of Motor-Driven Convenience Equipment for Harvesting Chili Peppers on Bare Ground | Purpose: Harvesting chili peppers is a very difficult task in chili pepper farming. It imposes a great burden on farmers, many of whom are old. Therefore, in this study, we proposed and fabricated a motor-driven convenience for harvesting chili peppers. This equipment is suitable for use in the local chili pepper farming environment to help workers harvest chili peppers conveniently. Methods: We proposed and fabricated a device by considering the physical body dimensions of farm workers and the chili pepper cultivation method. Moreover, we conducted an experiment to check the ultraviolet (UV) blocking performance of shading nets to develop a sun blocking device that protects workers from UV rays. The performance of the proposed device was evaluated through productivity verification by conducting harvesting tests and convenience analysis by using the Rapid Entire Body Assessment (REBA) tool. Results: The REBA score of the proposed motor-driven convenience equipment for harvesting chili peppers was one point, and harvest quantity per hour achieved with the motor-driven convenience equipment was 21% and 7% higher than those achieved with human labor and the manually driven convenience-type equipment, respectively. Conclusions: The proposed motor-driven convenience equipment for harvesting chili peppers improved the productivity of harvesting work compared to those of existing manual convenience equipment and human labor, in addition to improving work convenience. © 2020, The Korean Society for Agricultural Machinery. | Jang, Suk-Geun; Woo, Duk-Gam; Kim, Tae-Han | Department of Bio-industrial Machinery Engineering, Kyungpook National University, Daegu, 41566, South Korea; Research Faculty of Agriculture, Hokkaido University, Sapporo, 060-8589, Japan; Department of Bio-industrial Machinery Engineering, Kyungpook National University, Daegu, 41566, South Korea | 57218176695; 57210347680; 57204040387 | thakim@knu.ac.kr;dgwoo@bpe.agr.hokudai.ac.jp; | Journal of Biosystems Engineering | 1738-1266 | 45 | 1 | 0.11 | 2025-06-25 | 1 | Bare ground; Chili peppers; Convenience equipment; Ease of use analysis; Harvesting; REBA | Productivity; Bare grounds; Blocking performance; Body dimensions; Chili pepper; Farm workers; Human labor; Shading nets; Ultra-violet; Harvesting | English | Final | 2020 | 10.1007/s42853-020-00042-1 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Proceedings Paper | DEVELOPMENT OF PROTOTYPE OF TWO AXIS GIMBAL-TYPE PLATFORM IN UNDERWATER | The Bottom-mounted ocean-observation platforms installed on the seabed have been used for marine environment analysis. The role of the observing platform is to collect precise observation data without human assistance. However, their working environment is very harsh so the typical device could not afford to provide easy accessibility during their working period. Existing bottom-mounted ocean-observation platforms have been difficult to collect continuous observation data. Therefore, this paper suggests a new ocean-observation platform for precise measurement of the marine environment. Suggested platform uses a PID control method to be applied for error compensation of each axis of gimbal. To verify the system performance, the experiment was carried out in the air with the external force applied to this system. | Park, Hoonmin; Lee, Hyunjae; Ryu, Hongryul; Kim, Dongho; Kim, Hyunsoo; Park, Hyesoo; Lee, Sangryong; Yi, Hak | Kyungpook Natl Univ, Grad Sch, Dept Mech Engn, Daegu, South Korea; Hydrobot Tech & Res, Jeonju, South Korea; Korea Inst Machinery & Mat, Daegu, South Korea; Keyon Syst, Daegu, South Korea | yihak@knu.ac.kr; | PROCEEDINGS OF THE ASME 2020 INTERNATIONAL MECHANICAL ENGINEERING CONGRESS AND EXPOSITION, IMECE2020, VOL 7A | 0 | Product Development; Design; Robot Kinematics; Control | English | 2020 | 2020 | 바로가기 | ||||||||||||||||||||||||

| ○ | ○ | Proceedings Paper | Development of Tl-based Novel Scintillators | Inorganic scintillators containing heavy Thallium-(Tl) in the host lattices are the novel emerging class discovered by our research group. In this class of scintillators, we studied elpasolites, ternary lanthanide halides, ternary metal halides and Tl-based hafnium/zirconium halides. These materials were synthesized by conventional melting, rotating melt direction and sublimation techniques. The single crystals were grown by conventional and modified two zones vertical Bridgman techniques and the phases were analyzed by differential scanning calorimetry and powder X-rays diffraction analysis. The emission properties studied at room temperature under X-rays irradiation shown to have efficient intrinsic and Ce3+ or Eu2+ dopant luminescence, mostly in the 370-530 nm range i.e compatible with the spectral sensitivity response of modern photosensors. The scintillation properties studied under gamma-rays and alpha-particles irradiation shown to have good energy resolution, high light yield, faster timing response and good pulse shape discrimination. The heavy Tl ion give rise to high effective number and moderate densities to these scintillators, make them efficient for the detection of X- and gamma-rays. With the modification of crystal growth furnaces, materials synthesis techniques, and purification procedure the scintillation performance of these scintillators improved significantly. The discovery and development for new Tl-based efficient scintillators and improvement in scintillation performance of the already discovered Tl-based scintillators are under investigation and will be reported in our future work. | Kim, HongJoo; Khan, Arshad; Rooh, Gul; Phan Quoc Vuong; Kim, Sunghwan; Daniel, Joseph | Kyungpook Natl Univ, Dept Phys, Daegu 41566, South Korea; Abdul Wali Khan Univ, Dept Phys, Mardan 23200, Pakistan; Cheongju Univ, Dept Radiol Sci, Cheongju 41566, South Korea | ; Khan, Arshad/ABB-1566-2021; Kim, Hong Joo/AAE-1178-2022; Rooh, Gul/AAF-2076-2019 | 59051568100; 56017063700; 24401665700; 57207618553; 36165569900; 36145005300 | HARD X-RAY, GAMMA-RAY, AND NEUTRON DETECTOR PHYSICS XXII | 0277-786X | 1996-756X | 11494 | 0.78 | 2025-06-25 | 0 | 2 | Scintillators; Effective atomic number; Density; Pulse shape discrimination; Crystal growth; Synthesis; Detection efficiency | EFFICIENT SCINTILLATOR; CE3+; RAY; LUMINESCENCE | Crystal growth; Density; Detection efficiency; Effective atomic number; Pulse shape discrimination; Scintillators; Synthesis | Differential scanning calorimetry; Gamma rays; Hafnium compounds; Ionization; Irradiation; Metal halides; Neutron detectors; Scintillation; Scintillation counters; Spectroscopy; Thallium compounds; X rays; Crystal growth furnace; Inorganic scintillator; Pulse shape discrimination; Purification procedures; Scintillation performance; Scintillation properties; Spectral sensitivity; Vertical Bridgman technique; X ray detectors | English | 2020 | 2020 | 10.1117/12.2568532 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Diagnosis and management of Kawasaki disease | Kawasaki disease, also known as mucocutaneous lymph node syndrome, is a common form of vasculitis in childhood. Among the recent trends in Kawasaki disease, it is notable that the prevalence rate is increasing, and the proportion of Incomplete" Kawasaki disease is also increasing. A delayed diagnosis with prolonged fever can cause complications, such as coronary artery aneurysm and decreased myocardial contractility. These complications might lead to significant morbidity and mortality. Kawasaki disease is diagnosed when the patient meets the principal criteria for clinical symptoms. Following the diagnostic criteria can prevent overdiagnosis but lead to missing of the incomplete form of the disease. Therefore, it is important to accurately understand Kawasaki disease. As the coronavirus disease 2019 (COVID-19) pandemic continues, concerns about a novel severe Kawasaki-like disease in children related to COVID-19 emerges. Indeed, there have been several reports of Kawasaki-like disease related to COVID-19 in children. Kawasaki disease is no longer rare and is often encountered at hospitals. This paper will provide useful and accurate information on Kawasaki disease. | Roh, Do Eun; Kwon, Jung Eun; Kim, Yeo Hyang | Kyungpook Natl Univ, Childrens Hosp, Sch Med, Div Pediat Cardiol,Dept Pediat, Daegu, South Korea | 57195734230; 57194002366; 57032023800 | kimyhmd@knu.ac.kr; | JOURNAL OF THE KOREAN MEDICAL ASSOCIATION | J KOREAN MED ASSOC | 1975-8456 | 2093-5951 | 63 | 7 | ESCI | MEDICINE, GENERAL & INTERNAL | 2020 | N/A | 0 | 2025-06-25 | 2 | 2 | Mucocutaneous lymph node syndrome; Lymphadenopathy; Aspirin; Calmette-Guerin Bacillus vaccine; Intravenous immunoglobulins | MACROPHAGE ACTIVATION SYNDROME; CORONARY-ARTERY ABNORMALITIES; ACUTE-PHASE; ACUTE STAGE; RESISTANT; ASSOCIATION; CHILDREN; HISTORY; LESIONS | Aspirin; Calmette-Guerin Bacillus vaccine; Intravenous immunoglobulins; Lymphadenopathy; Mucocutaneous lymph node syndrome | Article; diagnostic accuracy; human; managed care; medical information; mucocutaneous lymph node syndrome | Korean | 2020 | 2020-07 | 10.5124/jkma.2020.63.7.374 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | Article | Disease awareness and treatment experience of patients with chronic obstructive pulmonary disease | Purpose: The purpose of this study was to explore patients' awareness and treatment experiences with Chronic Obstructive Pulmonary Disease (COPD) through in-depth interviews. The objective was to develop data to support patients in the successful management of their illness. Methods: Purposeful sampling was used to collect information- rich cases and participants were recruited at a university hospital in Daegu, South Korea. Data collection was done through face to face in-depth individual interviews with 10 patients with COPD from November 2016 to December 2018. Interview began with open-ended questions and each interview lasted on average one hour. All interviews were audio-taped and transcribed verbatim and transcripts were analyzed using qualitative thematic analysis. The findings were verified by the participants. Results: Four themes emerged from data analysis: 'Feeling like the disease is not my disease,' 'Terminology spills like a flood,' 'Negligent daily disease-management with relief,' and 'Relying on health professionals and family members hoping for healing'. Conclusion: Participants do not have a clear understanding of their illness nor feel that they are principal agents of their health and illness for treatment and disease management; instead, they depend mainly on their family members and doctors. The findings elucidated the need for increasing patients' awareness of the illness. Nurses should develop educational support programs to help COPD patients improve their awareness of their illness and successfully manage their treatment. © 2020 Korean Academy of Fundamentals of Nursing. | Noh, Hyun Jung; Kim, Su Hyun; Joung, Woo Joung | College of Nursing, Kyungpook National University, Daegu, South Korea; College of Nursing, Kyungpook National University, Daegu, South Korea; College of Nursing, Kyungpook National University, Daegu, South Korea | 57218999197; 56664542600; 56319847900 | suhyun_kim@knu.ac.kr; | Journal of the Korean Academy of Fundamentals of Nursing | 1225-9012 | 27 | 2 | 0.18 | 2025-06-25 | 1 | Awareness; Chronic obstructive pulmonary disease; Disease management; Qualitative research; Self-care | Korean | Final | 2020 | 10.7739/jkafn.2020.27.2.188 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Disseminated coccidioidomycosis in Africa | Background: Coccidioidomycosis is an endemic disease in the Americas. No cases have been reported in Africa. Patient: A 23-year-old HIV seronegative Ugandan man was referred to Mulago National Referral Hospital in Kampala, Uganda with a 10-month history of haemoptysis and difficulty breathing, and a 6-month history of localized swellings on the extremities. He had associated weight loss and drenching sweats, but no fevers. He had taken anti-tuberculosis medicine for 2 months with no improvement. He had never travelled out of Uganda. On physical examination, he had cystic swellings and ulcerated lesions on the extremities. He had tachypnoea, crackles in the chest and mild hepatomegaly. Bronchoscopic examination showed two masses occluding the right main bronchus. Bronchoscopic biopsy showed findings consistent with coccidioidomycosis. The patient improved with antifungal treatment and was discharged. Conclusion: We report the first case of disseminated coccidioidomycosis with pulmonary and cutaneous manifestations in Africa. LEARNING POINTS • Coccidioidomycosis is an endemic disease in the Americas and may now be present in Africa. • The patient had taken anti-tuberculosis medicine for 2 months with no improvement. • Coccidioidomycosis should be considered in the differential diagnosis of tuberculosis. © 2020 SMC Media Srl.

| ○ | Article | Dissolution of Lignin-Rich Organosolv Pulps by PEG and Urea Contents in Aqueous Alkaline Solution | In this study, we investigated the use of the contents of polyethylene glycol (PEG) and urea in sodium hydroxide (NaOH) aqueous solutions to dissolve lignin-rich organosolv pulps by evaluating dissolution yields and quality of dissolved organosolv pulp solutions towards further valorization. Unbleached pine organosolv pulp (UBOP) containing 26.8% residual lignin was prepared and then subsequently delignified with sodium chlorite to produce a delignified organosolv pulp (DOP) with 14.2% residual lignin content. It was found that lignin content of the organosolv pulps significantly impacted dissolution yield. Further, as PEG content increased in NaOH aqueous solutions, the dissolution yields of UBOP and DOP gradually decreased by an average of 18% and 20%, respectively. In contrast, the effect of urea on dissolution yield was dependent on lignin content of the feed and NaOH content in solution. The dissolution yield of UBOP increased by an average of 6% as urea, but in DOP, the dissolution yield did not change with increasing amounts of urea. In addition, residual lignin content of regenerated cellulose film fabricated from DOP dope in PEG/NaOH was higher than that found in urea/NaOH, indicating that a PEG/NaOH aqueous solution may be an effective dissolution solvent for cellulose, hemicellulose, and lignin. © 2020 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | ○ | Proceedings Paper | Distortional Hardening Behavior and Strength Different Effect of Pure Titanium Grade 1 Sheets: Experimental Observation and Constitutive Modeling | This study presents a systematic methodology that used to identify the subsequent yield surfaces of a pure titanium grade 1 sheet at different levels of equivalent plastic work. Several experimental tests including uniaxial tensile tests (UT), hydraulic bulge test (BT), simple shear tests (SS), and uniaxial compressive tests (UC) have been conducted for samples prepared in different orientations to achieve a comprehensive experimental data of yielding behaviors observed in different forming modes. Under the condition of equivalent plastic work, the yielding behaviors are characterized and normalized to clarify the distortional hardening behavior and strength different effect for the tested material. It is seen that the yielding surface of the tested material distorts largely during plastic deformations and approaches to its final shape at an equivalent plastic work value of 40 MPa. Under the plane-stress assumption, experimental data obtained from on-axis tests (UT, BT, UC) are used to calibrate three constitutive models: Yld2k, CPB06, and CB04. Finite element analyses for a simple shear test have been performed in Abaqus/explicit software to validate the developed material models. In conclusion, the CPB06 model provides the best prediction for plastic yielding behaviors of the tested material. | Pham, Quoc Tuan; Lee, Myoung Gyu; Kim, Young Suk | Ton Duc Thang Univ, Inst Computat Sci, Div Computat Math & Engn, Ho Chi Minh City, Vietnam; Ton Duc Thang Univ, Fac Civil Engn, Ho Chi Minh City, Vietnam; Seoul Natl Univ, Seoul 08826, South Korea; Kyungpook Natl Univ, 80 Daehak Ro, Daegu 41566, South Korea | Kim, Sang-Hoon/AAA-2248-2020; Pham, Quoc Tuan/AAH-8010-2019 | 57191753992; 26323686000; 57220180552 | phamquoctuan@tdtu.edu.vn;myounglee@snu.ac.kr;caekim@knu.ac.kr; | INTERNATIONAL DEEP-DRAWING RESEARCH GROUP (IDDRG 2020) | 1757-8981 | 967 | 0.34 | 2025-06-25 | 3 | 3 | ALLOYS | English | 2020 | 2020 | 10.1088/1757-899x/967/1/012052 | 바로가기 | 바로가기 | 바로가기 |
