| ○ | ○ | Article | Design of a Capacitorless DRAM Based on Storage Layer Separated Using Separation Oxide and Polycrystalline Silicon | In this study, a capacitorless one-transistor dynamic random-access memory (1T-DRAM) based on a polycrystalline silicon (Poly-Si) metal-oxide-semiconductor field-effect transistor (MOSFET) with a storage layer separated using a separation oxide was designed and analyzed using technology computer-aided design (TCAD). The channel and storage layers were separated using a separation oxide to improve the inferior retention time of the conventional 1T-DRAM, and we adopted the underlap structure to reduce Shockley-Read-Hall recombination. In addition, poly-Si, which has several advantages, including low manufacturing cost and availability of high-density three-dimensional (3D) memory arrays, is used to easily fabricate silicon-on-insulator (SOI)-like structures. Accordingly, we extracted memory performance by analyzing the effect of grain boundary (GB). The proposed 1T-DRAM achieved a sensing margin of 14.10 mu A/mu m and a retention time of 251 ms at T = 358 K, even in the existence of a GB. | Kim, Geon Uk; Yoon, Young Jun; Seo, Jae Hwa; Lee, Sang Ho; Park, Jin; Kang, Ga Eon; Heo, Jun Hyeok; Jang, Jaewon; Bae, Jin-Hyuk; Lee, Sin-Hyung; Kang, In Man | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Korea Atom Energy Res Inst, Korea Multipurpose Accelerator Complex, Gyeongju 38180, South Korea; Korea Electrotechnol Res Inst, Power Semicond Res Ctr, Chang Won 51543, South Korea | ; Lee, Sang Ho/MCX-8396-2025; Seo, Jae Hwa/KYP-7367-2024; Lee, Sin-Hyung/ABD-6425-2022 | 57727029200; 57218864885; 58837410100; 57416738400; 57376422900; 57883409400; 57884155500; 57194107504; 35326180700; 57226880204; 7203062678 | imkang@ee.knu.ac.kr; | ELECTRONICS | 2079-9292 | 11 | 20 | 0.23 | 2025-06-25 | 4 | 3 | one-transistor dynamic random-access memory; metal-oxide-semiconductor field-effect transistor; polycrystalline silicon | 1T-DRAM; MEMORY; TRANSISTOR; TECHNOLOGY | metal-oxide-semiconductor field-effect transistor; one-transistor dynamic random-access memory; polycrystalline silicon | English | 2022 | 2022-10 | 10.3390/electronics11203365 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Design Optimization of a 4-2 Compressor for Low-cost Approximate Multipliers | Approximate computing can enhance hardware efficiency for error-tolerant applications. This technique can be applied to basic arithmetic operations such as multiplication. Approximate multiplication is generally implemented using several approximate compressors. In this paper, we propose an optimized 4-2 approximate compressor based on an existing compressor. We elaborate Boolean expressions for the compressor to replace the original gates with compound gates that reduce the hardware resource consumption. Compared to the original design, the optimized compressor's area and power are improved by 62.5% and 65.7%, respectively. When the proposed compressor is applied to multiplier configurations, it reduces the area and power by at least 13%. Additionally, our simulation results show that it achieves better hardware performance than other approximate compressors.

| ○ | ○ | Article | Design, implementation, and outcomes of an in-service program with photovoice as a pedagogical tool for geography teachers | The purpose of this study was to introduce photovoice as a pedagogical tool in an in-service program for geography teachers, demonstrate the implementation of this methodology, and examine its outcomes, strengths, and weaknesses. The applicability of photovoice as a pedagogical tool for secondary school geography as well as its strengths and weaknesses were clarified. As a pedagogical tool for geography, photovoice not only allowed in-service geography teachers to develop critical thinking, but also fostered active citizenship. In addition, photovoice afforded in-service geography teachers the opportunity to capture the public geography learned in the classroom in the field and subsequently add their own voice to discover their own personal geography. Despite these strengths, in order for geography teachers to employ photovoice in their classes, issues such as time, evaluation, place, and safety as well as inviting decision-makers and policymakers to the presentation process are challenges that need to be addressed. As this study focuses on geography teacher education, further research needs to be done with younger students. | Cho, Chul-Ki; Kim, Byung-Yeon; Stoltman, Joseph P. | Kyungpook Natl Univ, Dept Geog Educ, Daegu, South Korea; Dasa High Sch, 839 Dalgubeol Daero, Daegu 42910, South Korea; Western Michigan Univ, Dept Geog, Kalamazoo, MI 49008 USA | KIM, BYUNGYEON/HTP-3607-2023 | 57221970337; 57221967006; 6602898699 | briet@hanmail.net; | INTERNATIONAL RESEARCH IN GEOGRAPHICAL AND ENVIRONMENTAL EDUCATION | INT RES GEOGR ENVIRO | 1038-2046 | 1747-7611 | 31 | 2 | ESCI | EDUCATION & EDUCATIONAL RESEARCH | 2022 | 1.8 | 0.88 | 2025-06-25 | 5 | 8 | In-service program; pedagogical tool; photovoice; strengths and weaknesses | PROFESSIONAL-DEVELOPMENT; METHODOLOGY; KNOWLEDGE | In-service program; pedagogical tool; photovoice; strengths and weaknesses | decision making; design method; implementation process; photovoltaic system; research work; teacher training | English | 2022 | 2022-04-22 | 10.1080/10382046.2021.1924983 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Book chapter | Detection of Sensor Fault in a DC Microgrid Using Supertwisting Observer | The detection of sensor faults in a direct current (DC) microgrid is essential to provide a safe and uninterrupted supply of power. The fault detection techniques in the DC microgrid should involve immediate sensor fault detections to protect the system from adverse effects. To address this issue, in this paper, a fault detection technique is designed which addresses the scenario where the interconnected distributed generation units (DGUs) are affected by sensor faults in a DC microgrid. Multiplicative faults in the grid-connected voltage and current sensors are considered. A model-based multiple sliding mode observers (HOSM) are designed to estimate the states of the DGUs, and faulty sensors are detected based on the generated residuals. The stability of the overall microgrid system can be achieved by designing a hierarchical controller which ensures uniform current sharing among all the DGUs. The validation of the proposed method is supported through extensive MATLAB simulations for various arrangements of the DC microgrid subjected to numerous known and unknown disturbances. A common threshold is selected from the multiple simulations for sensor fault detection. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. | Narzary, Daijiry; Swain, Subrat Kumar; Rath, Jagat; Veluvolu, Kalyana C. | School of Electronics Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, Kyungpook National University, Daegu, South Korea; Institute of Infrastructure Technology Research and Management, Gujarat, Ahmedabad, 380026, India; School of Electronics Engineering, Kyungpook National University, Daegu, South Korea | 57201854373; 57196716965; 55904945200; 8703318200 | veluvolu@ee.knu.ac.kr; | Lecture Notes in Intelligent Transportation and Infrastructure | 2523-3440 | Part F1361 | 0 | 2025-06-25 | 0 | DC microgrid; DGUs; Fault detection; HOSM observer; LMI; Renewable energy; Sensor faults | English | Final | 2022 | 10.1007/978-981-16-7660-4_12 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | Determination of Astrophysical S Factor for 15N(p;γ)16O at Low-energies Within Effective Field Theory | The radiative proton capture on 15N targets, i.e., 15N(p; γ)16O, is an important thermonuclear reaction of the CNO cycle in stellar environments. This reaction is a key process in the cycle because it initiates the NO cycle by producing 16O. In this study, we investigated the 15N(p; γ)16O reaction within the framework of cluster effective field theory. We construct an effective Lagrangian to describe the reaction at stellar energies and calculate the astrophysical S factor. The parameters of our calculations, such as low-energy constants, resonance energy, and decay width of the 16O resonance are determined by fitting empirical data of the S factor at the range of 72:8 keV ≤ Ecm ≤ 368:3 keV. The S factor value for this reaction at extremely low energy is then determined to be S E = 0 = 30:4 keV b, which is consistent with the estimates of R-matrix approaches. © 2022 The Korean Physical Society.

| ○ | Article | Development and application of environmental education program for inservice geography teachers using community mapping and photovoice | This study designed an environmental education program for in-service geography teachers using community mapping and photovoice methodology and applied it to in-service geography teachers to derive results. In addition, the study explored the possibilities and implications of these two participatory research techniques as pedagogical tools for geographical and environmental education. In-service geography teachers confirmed that community mapping activities combined with the photovoice methodology can support the development of the geographical skills and spatial thinking about the environment of students. Moreover, they recognized that the program is a useful pedagogical tool for connecting learners with geographical communities to actively explore various geographical and environmental issues in the region, connecting them inside and outside the classroom and reaching an in-depth understanding of geographical and environmental issues through the production of knowledge that expresses their perspectives and experiences. Furthermore, the program, which combines community mapping and photovoice, can be an effective pedagogical tool for fostering community competence and active citizenship in that participants actively participate in the community to create better community change. © 2022 by the authors; licensee Modestum.

| ○ | ○ | Article | Development and Evaluation of a Pillow to Prevent Snoring Using the Cervical Spine Recurve Method | Snoring lowers the quality of sleep, causing many secondary diseases. In response, various types of preventive devices were manufactured, but most of them were far from actual snoring prevention by only sensing snoring and giving feedback. In this study, we proposed a new method to prevent snoring by adjusting the posture during sleep by widening the oropharynx space. An increase in the oropharynx area was confirmed through the expansion of the cervical spine, and a dedicated pillow that can extend through an angle of up to 20 degrees was manufactured. Through this developed method, it was possible to easily extend the cervical spine angle in a supine position to the user, and the frequency of snoring was then tested. As a result, it was confirmed that by using the pillow with an expansion angle of 20 degrees or more, snoring did not occur. Furthermore, looking at the evaluation results of the subjective levels of satisfaction, sleep-related items received an average of 5.9 or higher, and function-related items received high scores with an average of 5.7. We can confirm that the reliability of performance evaluation will be dramatically improved if the scope of the subject group is expanded to include various body types, ages, and genders and conduct performance evaluations for each group. | Ahn, Dohyun; Choi, Hyeunwoo; Lee, Jongmin; Heo, Sung-Phil | Kyungpook Natl Univ, Dept Med & Biol Engn, Daegu 41566, South Korea; Mol Hemodynam & Computat Lab, Daegu 41566, South Korea; Kyungpook Natl Univ Hosp, Daegu 41944, South Korea; Gangneung Wonju Natl Univ, Dept Informat & Commun Engn, Gangneung Si 25457, South Korea | Lee, Jongmin/AAR-6361-2020 | 57204761890; 57209912547; 55689919700; 57214464666 | tigerace5012@nate.com;chwoo717@hanmail.net;jonglee@knu.ac.kr;spheo@gwnu.ac.kr; | JOURNAL OF HEALTHCARE ENGINEERING | 2040-2295 | 2040-2309 | 2022 | 0.11 | 2025-06-25 | 1 | 1 | OBSTRUCTIVE SLEEP-APNEA; HYPOPNEA; PRESSURE; IMPACT | Bedding and Linens; Cervical Vertebrae; Female; Humans; Male; Neck; Reproducibility of Results; Snoring; Cervical spine; Evaluation results; Expansion angles; Level of satisfaction; Oropharynx; Performances evaluation; Preventive devices; Secondary disease; Supine position; Article; body movement; body position; cervical spine; cervical spine recurve; cervical vertebra; clinical assessment; clinical evaluation; controlled study; female; human; male; mandible; oropharynx; patient satisfaction; sleep; snoring; supine position; bed; neck; reproducibility; snoring | English | 2022 | 2022-08-17 | 10.1155/2022/2561107 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Development and validation of an analytical method to quantify baphicacanthin A by LC-MS/MS and its application to pharmacokinetic studies in mice | In this study, we developed and validated a sensitive analytical method to quantify baphicacanthin A in mouse plasma using liquid chromatography-tandem mass spectrometry (LC-MS/MS). The standard calibration curves for baphicacanthin A ranged from 0.5 to 200 ng/mL and were linear, with an r(2) of 0.985. The inter- and intra-day accuracy and precision and the stability fell within the acceptance criteria. Besides, we investigated the pharmacokinetics of baphicacanthin A following its intravenous (5 mg/kg) and oral administration (30 mg/kg). Intravenously injected baphicacanthin A showed biphasic elimination kinetics with high clearance and volume of distribution values. Furthermore, baphicacanthin A showed a rapid absorption but low aqueous solubility (182.51 +/- 0.20 mg/mL), resulting in low plasma concentrations and low oral bioavailability (2.49 %). Thus, we successfully documented the pharmacokinetic properties of baphicacanthin A using this newly developed sensitive LC-MS/MS quantification method, which could be used in future lead optimization and biopharmaceutic studies. | Jeon, So Yeon; Kim, San; Park, Jin-Hyang; Song, Im-Sook; Han, Young Taek; Choi, Min-Koo | Dankook Univ, Coll Pharm, Cheonan 31116, South Korea; Kyungpook Natl Univ, BK21 FOUR Community Based Intelligent Novel Drug, Vessel Organ Interact Res Ctr VOICE, Coll Pharm, Daegu 41566, South Korea; Kyungpook Natl Univ, Pharmaceut Sci Res Inst, Daegu 41566, South Korea | 57226815842; 57678229600; 57267338300; 7201564500; 36097949800; 8695781400 | hanyt@dankook.ac.kr;minkoochoi@dankook.ac.kr; | ANALYTICAL SCIENCE AND TECHNOLOGY | ANAL SCI TECHNOL | 1225-0163 | 2288-8985 | 35 | 2 | ESCI | CHEMISTRY, ANALYTICAL | 2022 | 0.3 | 0 | 2025-06-25 | 0 | 0 | baphicacanthin A; analytical method validation; LC-MS/MS; bioavailability | BIOACTIVE DIETARY BENZOXAZINOIDS; RYE BREAD; ABSORPTION | analytical method validation; baphicacanthin A; bioavailability; LC-MS/MS | English | 2022 | 2022-04 | 10.5806/ast.2022.35.2.60 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Development and Validation of Earthquake Fire Response Simulation Protocol for Korean College Students in Health Programs | The purpose of this study is to evaluate the adequacy of the developed protocol by verifying the validity of the expert group for the earthquake and fire response simulation protocol. A protocol development team consisting of one emergency rescue professor, one counseling psychology professor, three paramedics, and one firefighter developed the study's protocols to promote the core response and capabilities required at an earthquake fire site. We checked the content validity for the appropriateness of the contextual connection for each stage for the protocol. We also created an evaluation checklist to measure the items for each stage. The protocol developed in this study consists of earthquake response, fire response, evacuation, and fire suppression. We set the situation for each stage and composed learner activities and learning performance goals. The earthquake response stage included (1) shout "it's an earthquake," (2) protect yourself, (3) turn off electricity and gas, and (4) evacuate to a safe place. In the fire response stage, (1) shout "fire," (2) press the emergency bell and call 119, (3) close the door of a dangerous place where fire can spread, and (4) evacuate to a safe place. In the evacuation stage, (1) open the emergency exit, (2) cover your nose and mouth, (3) lower your posture, and (4) evacuate quickly in one direction. Lastly, in the firefighting stage, (1) pull out the safety pin, (2) hold the nozzle and face the fire, (3) grab the handle, and (4) spray the powder evenly. The protocol contributes to the development of systematic and elaborate simulation education materials in the future. Furthermore, it provides basic data for future disaster simulation operation and protocol development through continuous training and practical exercises. | Jung, Hyun-Ok; Han, Seung-Woo | Kyungpook Natl Univ, Coll Nursing, Daegu 41944, South Korea; Kyungil Univ, Dept Emergency Med Technol, Gamasilgil Hayangeup, Gyongsan 38428, South Korea | 57224449640; 57210797256 | juiris@korea.kr;swhan@kiu.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 9 | 0.09 | 2025-06-25 | 2 | 1 | disaster safety; earthquake response; fire response; evacuation; fire suppression; disaster response capacity | DISASTER | disaster response capacity; disaster safety; earthquake response; evacuation; fire response; fire suppression | Disaster Planning; Disasters; Earthquakes; Humans; Republic of Korea; Students; Korea; computer simulation; disaster management; earthquake event; fire management; future prospect; hazard assessment; health and safety; higher education; model validation; natural disaster; numerical model; student; adult; Article; awareness; checklist; clinical evaluation; clinical protocol; college student; controlled study; disaster preparedness; earthquake and fire response simulation protocol; emergency evacuation; emergency response time; female; health program; human; human experiment; Korean (people); male; methodology; middle aged; normal human; performance; process development; simulation; validation process; disaster; disaster planning; earthquake; procedures; South Korea; student | English | 2022 | 2022-05 | 10.3390/ijerph19095764 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Development of a Frailty Detection Model Using Machine Learning with the Korean Frailty and Aging Cohort Study Data | Objectives: This paper aimed to use machine learning to identify a new group of factors predicting frailty in the elderly population by utilizing the existing frailty criteria as a basis, as well as to validate the obtained results. Methods: This study was conducted using data from the Korean Frailty and Aging Cohort Study (KFACS). The KFACS participants were classified as robust or frail based on Fried's frailty phenotype and excluded if they did not properly answer the questions, resulting in 1,066 robust and 165 frail participants. We then selected influential features through feature selection and trained the model using support vector machine, random forest, and gradient boosting algorithms with the prepared dataset. Due to the im-balanced distribution in the dataset with a low sample size, holdout was applied with stratified 10-fold and cross-validation for estimating the model performance. The reliability of the constructed model was validated using an unseen test set. The model was then trained with hyperparameter optimization. Results: During the feature selection process, 27 features were identified as meaningful factors for frailty. The model was trained based on the selected features, and the weighted average F1-score reached 95.30% with the random forest algorithm. Conclusions: The results of the study demonstrated the possibil-ity of adopting machine learning to strengthen existing frailty criteria. As the method analyzes questionnaire responses in a short time, it can support higher volumes of data on participants' health conditions and alert them regarding potential risks in advance. | Koo, Dongjun; Lee, Ah Ra; Lee, Eunjoo; Kim, Il Kon | Kyungpook Natl Univ, Coll IT Engn, Sch Comp Sci & Engn, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Nursing Sci, Coll Nursing, Daegu, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Comp Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; koo, dongjun/HKE-1497-2023 | 57851155100; 57207456585; 56502620400; 14919454400 | ikkim@knu.ac.kr; | HEALTHCARE INFORMATICS RESEARCH | HEALTHC INFORM RES | 2093-3681 | 2093-369X | 28 | 3 | ESCI | MEDICAL INFORMATICS | 2022 | 2.9 | 0.51 | 2025-06-25 | 7 | 6 | Frailty; Aged; Dyskinesias; Surveys and Questionnaire; Machine Learning | OLDER-ADULTS; DEPRESSION; VERSION | Aged; Dyskinesias; Frailty; Machine Learning; Surveys and Questionnaire | English | 2022 | 2022-07 | 10.4258/hir.2022.28.3.231 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of a Standardized Curriculum for Nursing Informatics in Korea | Objectives: This study explored the current status of nursing informatics education in South Korea and developed a stan-dardized curriculum for it. Methods: Data were collected in two stages: first, an online survey conducted from December 2020 to February 2021 among 60 nursing schools to analyze the current status of nursing informatics education; and second, a two-round Delphi survey with 15 experts from March to April 2021 to determine the mean and standard deviation of the demand for each learning objective in nursing informatics education. A standardized curriculum proposal was developed based on the results of the two-round Delphi survey. Results: Nursing informatics was most commonly taught in the fourth year (34%), with two credits. The proportion of elective major subjects was high in undergraduate and graduate programs (77.4% and 78.6%, respectively), while the proportion of nursing informatics majors was low (21.4%). The curriculum devel-oped included topics such as nursing information system-related concepts, definitions and components of healthcare infor-mation systems, electronic medical records, clinical decision support systems, mobile technology and health management, medical information standards, personal information protection and ethics, understanding of big data, use of information technology in evidence-based practice, use of information in community nursing, genome information usage, artificial intel-ligence clinical information systems, administrative management systems, and information technology nursing education. Conclusions: Nursing informatics professors should receive ongoing training to obtain recent medical information. Further review and modification of the nursing informatics curriculum should be performed to ensure that it remains up-to-date with recent developments. | Park, Myonghwa; Dlamini, Bonkhe Brian; Kim, Jahyeon; Kwak, Min-Jung; Cho, Insook; Choi, Mona; Lee, Jisan; Min, Yul Ha; Park, Bu Kyung; Lee, Seonah | Chungnam Natl Univ, Coll Nursing, Daejeon, South Korea; Inha Univ, Coll Med, Dept Nursing, Incheon, South Korea; Yonsei Univ, Mo Im Kim Nursing Res Inst, Coll Nursing, Seoul, South Korea; Hoseo Univ, Coll Life & Hlth Sci, Dept Nursing Sci, Asan, South Korea; Kangwon Natl Univ, Coll Nursing, Chunchon, South Korea; Kyungpook Natl Univ, Coll Nursing, Daegu, South Korea; Chonnam Natl Univ, Coll Nursing, Gwangju, South Korea; Chungnam Natl Univ, Coll Nursing, Educ & Res Ctr Evidence Based Nursing Knowledge, 266 Munhwa Ro, Daejeon 35015, South Korea | Min, Yul Ha/JOK-7614-2023; Lee, Jisan/AAT-8516-2021; Choi, Mona/AGJ-1918-2022 | 7404490283; 57961206100; 57226835487; 57210786938; 55858319500; 14420709500; 56734179800; 57197055549; 57199829070; 57198819905 | bonkhedlamini22@gmail.com; | HEALTHCARE INFORMATICS RESEARCH | HEALTHC INFORM RES | 2093-3681 | 2093-369X | 28 | 4 | ESCI | MEDICAL INFORMATICS | 2022 | 2.9 | 0.6 | 2025-06-25 | 5 | 7 | Nursing Informatics; Curriculum; Health Information Systems; Education; Nursing Schools | EDUCATION; COMPETENCES | Curriculum; Education; Health Information Systems; Nursing Informatics; Nursing Schools | adult; article; big data; clinical decision support system; community health nursing; curriculum; Delphi study; education; electronic medical record; ethics; evidence based practice center; female; health care management; human; human experiment; identifiable information; information technology; learning; male; medical information system; nursing education; nursing informatics; nursing information system; South Korea | English | 2022 | 2022-10 | 10.4258/hir.2022.28.4.343 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Development of a Water bag System for Focal Depth Control of Single Transducer based Focused Ultrasound | Herein, the development of an applicator for coupling between the ultrasound transducer and human skin in a focused transcranial ultrasound (FUS) system is proposed. Generally, applicators that use a single element have the problem of a fixed-depth stimulating point because the focal point of ultrasound is around the transducer radius of curvature. This study proposes a method to increase the degree of freedom of selecting a stimulus depth, including in the coupling method, using a single-element transducer. This is achieved by developing a pump system, which connects to the water bag-based applicator to actively change the amount of water in the water bag and, thus, the position of the focal point. Herein, the water-bag-based applicator was developed and it was verified that there was no ultrasonic loss through sound field experiments. Additionally, a control system was developed to actively change the amount of water in the water bag when the desired stimulation depth is determined by deriving a relationship between the depth of the focal point of the transducer according to the volume change of the water bag. An average error of 0.26 mm was obtained from experiments. Lastly, a cooling system was developed to cool the water bag, and it was observed that water at 70 °C could be cooled to 40.3° C in 10 min. © ICROS 2022. | Kim, Dong-Hyeon; Park, Haejune; Kim, Cheol; Seo, Joonho | Korea Institute of Machinery & Materials, South Korea, Department of Mechanical Engineering, Kyungpook National University, South Korea; Korea Institute of Machinery & Materials, South Korea; Department of Mechanical Engineering, Kyungpook National University, South Korea; Korea Institute of Machinery & Materials, South Korea | 59784077700; 57210446574; 55508786300; 35761296900 | kimchul@knu.ac.kr;jhseo@kimm.re.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 28 | 2 | 0 | 2025-06-25 | 0 | Applicator; Brain stimulation; FUS; Single element transducer; ultrasound | Acoustic fields; Degrees of freedom (mechanics); Ultrasonic transducers; Ultrasonics; Brain stimulation; Depth control; Focal depth; Focal points; Focused transcranial ultrasound; Focused ultrasound; Human skin; Single element transducers; Transcranial ultrasound; Ultrasound transducers; Applicators | Korean | Final | 2022 | 10.5302/j.icros.2022.21.0189 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Development of an Assistive Device for Improving the Consistency and Safety of Nasopharyngeal Swab Sampling | This study proposes a new assistive device that ensures consistency and improves safety in sample collection for detecting upper respiratory diseases such as COVID-19. The COVID-19 pandemic and the various mutations of the coronavirus have increased the demand for swab-sampling–based specimen collection. Currently, the most accurate method of collecting respiratory specimens is to insert a cotton swab through the nasal passage and touch the nasopharyngeal wall. Here, the success of sampling is subjectively determined by the force applied to the swab; test results may therefore vary based on the degree of training of the medical staff, and excess force can sometimes cause pain and aftereffects in patients. Therefore, we developed a device that measures the force applied to the swab when it is inserted up to the nasopharyngeal wall and indicates this to medical staff with an audiovisual signal. In this study, we introduce the details of the sample collection devices and validate the developed device through phantom model experiments. The results of five model experiments confirm that when both visual and auditory signals were given to medical staff, more consistent swab sampling was achieved than the conventional method without signals. © ICROS 2022. | Kim, Dong-Hyeon; Park, Haejune; Lee, Chang-Hwa; Shim, Seongbo; Kim, Cheol; Seo, Joonho | Korea Institute of Machinery & Materials, South Korea, Department of Mechanical Engineering, Kyungpook National University, South Korea; Korea Institute of Machinery & Materials, South Korea; Department of Mechanical Engineering, Yeungnam University, South Korea; Korea Institute of Machinery & Materials, South Korea; Department of Mechanical Engineering, Kyungpook National University, South Korea; Korea Institute of Machinery & Materials, South Korea | 59784077700; 57210446574; 57871720400; 57113042000; 55508786300; 35761296900 | jhseo@kimm.re.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 28 | 9 | 0 | 2025-06-25 | 0 | Assistive device for swab sampling; COVID-19; Nasopharyngeal swab; Respiratory disease | Personnel training; Pulmonary diseases; Sampling; Assistive device for swab sampling; Assistive devices; Collection device; Coronaviruses; Model experiments; Nasopharyngeal swab; Phantoms; Sample collection; Sampling-based; Swab sampling; COVID-19 | Korean | Final | 2022 | 10.5302/j.icros.2022.22.0099 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Proceedings Paper | Development of an Autonomous Mobile Robot in the Outdoor Environments with a Comparative Survey of LiDAR SLAM | A high-precision mapping is one of the essential requirements for safe autonomous driving because it is directly connected with the accuracy and safety of autonomous driving. Due to the development of 3D light detection and ranging (LiDAR) sensor technology, LiDAR is playing a key role to create the precise maps. Although many open-source-based LiDAR simultaneous localization and mapping (SLAM) algorithms have been developed, their accuracy in actual experiments is often not proven. To handle this issue, our paper aims to provide background materials for autonomous robots and experimental validations of open-source-based LiDAR SLAM. In the experiments, the comparison results with four state-of-the-art LiDAR mapping algorithms are described including LiDAR odometry and mapping(LOAM) and LiDAR inertial odometry mapping. | Kim, Minsu; Zhou, Miaojun; Lee, Seoungwoo; Lee, Hyeonbeom | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | hbeomlee@knu.ac.kr; | 2022 22ND INTERNATIONAL CONFERENCE ON CONTROL, AUTOMATION AND SYSTEMS (ICCAS 2022) | 2093-7121 | 3 | LiDAR Odometry; SLAM; Sensor fusion; Survey; Drift error | English | 2022 | 2022 | 바로가기 | |||||||||||||||||||||||
