| ○ | Article | Fabrication of a Microfluidic Device with an Embedded PDMS Microstencil for Co-Culture of Cells; [PDMS 마이크로 스텐실이 내재된 세포공동배양 미세유체 장치 제작] | In this paper, a microfluidic co-culture system comprising an embedded polydimethylsiloxane (PDMS) microstencil was fabricated. The fabricated co-culture system has two micro-channels separated with a PDMS microstencil membrane. Master molds for microchannels and stencil membranes were fabricated by photolithography, then used for casting of PDMS devices. The stencil membrane was 10 thick, with holes 10-µm large in diameter. The fabricated system co-cultured two types of cells (HepG2, NIH-3T3 Cells) successfully for seven days. The viability and stability of the cells were verified through LIVE/DEAD® staining and analysis. Additionally, albumin secretion of HepG2 cells was measured for seven days, using an HSA ELISA kit. The measured data were analyzed, to compare the activity of HepG2 cells. Results confirmed that cells can be co-cultured in the fabricated microfluidic system.

| ○ | Article | Fabrication of High-Performance Colorimetric Fiber-Type Sensors for Hydrogen Sulfide Detection | Hydrogen sulfide(H2S) gas is a high-risk gas that can cause suffocation or death in severe cases, depending on the concentration of exposure. Various studies to detect this gas are still in progress. In this study, we demonstrate a colorimetric sensor that can detect H2S gas using its direct color change. The proposed nanofiber sensor containing a dye material named Lead(II) acetate, which changes its color according to H2S gas reaction, is fabricated by electrospinning. The performance of this sensor is evaluated by measuring RGB changes, ΔE value, and gas selectivity. It has a ΔE value of 5.75 × 10-3 ΔE/s•ppm, showing improved sensitivity up to 1.4 times that of the existing H2S color change detection sensor, which is a result of the large surface area of the nanofibers. The selectivity for H2S gas is confirmed to be an excellent value of almost 70%. © 2022, Korean Sensors Society.

| ○ | Book chapter | Fabrications and applications of polymer–graphene nanocomposites for sustainability | Graphene (GN) and GN-based composites have perceived more attention due to their large surface area, excellent compatibility, low mass density, significant flexibility, as well as the exceptional synergistic effect of GN with inorganic/organic materials. Several studies have been carried out on the fabrication of GN/polymer nanocomposites (GPNCs) with novel and enhanced properties. However, several methods and chemical alterations have been used to efficiently disperse the GN within the polymer matrices for better performances and wider applications of the fabricated GPNCs. The present chapter begins with the introduction, historical background, and synthesis method of GPNCs. Moreover, modification techniques and interaction of GN with different polymers and their diverse applicabilities as biomedical, drug delivery, water purification, and sensors are discussed in brief. © 2022 Elsevier Inc.

| ○ | ○ | Article | Factor Analysis Affecting Degree of Depression in Family Caregivers of Patients with Spinal Cord Injury: A Cross-Sectional Pilot Study | This study was conducted to determine the degree of depression in family caregivers of spinal-cord-injury patients and to identify factors influencing family caregivers' depression. The final study subjects were 30 (family caregivers: 6 males and 24 females). The CES-D of family caregivers; general characteristics of spinal-cord-injury patients and family caregivers; and information on physical health, household income, leisure, social activity, family relationship, and life-in-general status of family caregiver were collected. A frequency analysis, normality test, Mann-Whitney test, Kruskal-Wallis test, Spearman Correlation analysis, hierarchical regression analysis, and spider network through a path model analysis were performed. As for the general characteristics, when the patient was economically active, the caregiver's depression was mean +/- SD; 2.04 +/- 0.71; otherwise, it was mean +/- SD 2.86 +/- 0.74, indicating that the caregiver of the non-economic activity patient was more depressed (p = 0.013). In Model 1 of the multiple regression analysis to understand the effect on the depression of the caregiver, it was confirmed that the depression of the caregiver decreased as the family caregiver had more leisure and social activities (B = -0.718, p = 0.001). In Model 2, it was found that the depression of caregivers increased when the patient did not engage in economic activity (B = 0.438, p = 0.016). In the spider-web form through the path model analysis, as the family's economic level increased, physical health increased by B = 0.755 (p < 0.001), and the increase in physical health (B = 0.424, p = 0.042) was, in turn, a factor in the increase of engagement in leisure and social activities. Various policies will be needed for the successful return to society of spinal-cord-injury patients by ensuring that their leisure and social activities and establishing measures to support their economical income. | Lee, Su-Jin; Kim, Myung-Gwan; Kim, Jung Hee; Min, Yu-Sun; Kim, Chul-Hyun; Kim, Kyoung-Tae; Hwang, Jong-Moon | Kyungpook Natl Univ, Grad Sch Publ Hlth, Daegu 41944, South Korea; CHA Univ, Dept Biomed Informat, Sch Med, Seongnam 13415, South Korea; CHA Univ, Inst Biomed Informat, Sch Med, Seongnam 13415, South Korea; Chungbuk Natl Univ, Coll Pharm, Ind Pharm, Cheongju 28644, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Rehabil Med, Chilgok Hosp, Daegu 41404, South Korea; Kyungpook Natl Univ Hosp, Dept Rehabil Med, Daegu 41944, South Korea; Kyungpook Natl Univ Hosp, Dept Neurosurg, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu 41944, South Korea | 57207933350; 57217987383; 57847685400; 48061349800; 59603554500; 57201369790; 56367634000 | nskimkt7@gmail.com;hti82@hanmail.net; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 17 | 0.36 | 2025-06-25 | 3 | 4 | spinal cord injuries; caregivers; caregiver-family; family caregiver; caregiver-spouse; caregiver burden; depression | BURDEN; EPIDEMIOLOGY; INDIVIDUALS; SPOUSES; SUPPORT | caregiver burden; caregiver-family; caregiver-spouse; caregivers; depression; family caregiver; spinal cord injuries | factor analysis; household income; injury; mental disorder; social behavior; adult; Article; caregiver; correlation analysis; cross-sectional study; demographics; depression; depression assessment; deterioration; factor analysis; female; frequency analysis; health; household income; human; Kruskal Wallis test; leisure; life satisfaction; male; pilot study; questionnaire; regression analysis; social behavior; social support; spinal cord injury; spouse | English | 2022 | 2022-09 | 10.3390/ijerph191710878 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Factors Affecting City Image During the COVID-19 Era1 | This study examined the perceived contingent factors that affect South Korean citizens’ image of the city they reside in. The respondents in this study perceived the image of their city through two dimensions––leading and safe––during the COVID-19 era. When respondents perceived the openness and expertise of the local government, the transformational and transactional leadership of the government leader, liberal political orientation of the leader, lower degree of law compliance of the mayor, high degree of citizenship, and high level of living infrastructure and competitiveness as attributes of the city, they were more likely to perceive the city as having a “leading” image. The perceived cultural characteristics of the local government, specifically the factor of hierarchy and regulation, the perceptions of citizenship, and all three variables regarding the perceptions related to city attributes (i.e., environmental, cultural, and living infrastructures and competitiveness) positively influenced the perception of a “safe” city image. Based on the results, various theoretical and practical implications were discussed in this study. © 2022, Center for Asian Public Opinion Research and Collaboration Initiative.

| ○ | Article | Factors Affecting Nursing Performance for Patients after Attempted Suicide among Clinical Nurses | Purpose: This study aimed to identify the factors that influence nursing performance for patients after attempted suicide among clinical nurses. Methods: The participants in this study were 200 clinical nurses working at hospitals in Korea. Data was collected from February 22, 2022 to March 18, 2022 through a structured online survey that included general characteristics, suicide literacy, attitudes towards suicide, social stigma toward suicidal people, and nursing performance for patients after attempted suicide. SPSS/WIN 25.0 program was used for data analysis, including a descriptive analysis, t-test, one way analysis of variance, the Scheffé test, Pearson correlation coefficients, and multiple linear regression. Results: A higher level of suicide literacy (r=.36, p<.001) and attitudes towards suicide (r=.23, p<.001) were associated with higher nursing performance for patients after attempted suicide. The factors affecting nursing performance for patients after attempted suicide were suicide literacy (β=.38, p<.001) and attitudes towards suicide (β=.26, p<.001). This model showed a 18.0% explanation of nursing performance for patients after attempted suicide. Conclusion: It is necessary to develop an effective educational program and to establish an organizational system to improve the quality of nursing performance for patients after attempted suicide. 2022 Korean Academy of Fundamentals of Nursing. | Kang, Young Hee; Kim, Yujeong | Graduate Student, Department of Forensic Nursing, Kyungpook National University, Daegu, South Korea; College of Nursing, Research Institute of Nursing Science, Kyungpook National University, Daegu, South Korea | 58031386600; 57200941945 | yujeongkim@knu.ac.kr; | Journal of the Korean Academy of Fundamentals of Nursing | 1225-9012 | 29 | 4 | 0 | 2025-06-25 | 0 | Attempted suicide; Hospital nursing service; Nurses; Social stigma | Korean | Final | 2022 | 10.7739/jkafn.2022.29.4.441 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Factors enhancing independent tourists' experience through convergence of smartphone-based services and information searching | The aim of the present study is to identify influential factors of travel intention under the context of highly developed IT society today. Due to the development of IT and diversified ways of technology convergence, individual travelers become highly efficient in travel-related information processing. As predicted, the results of both Korean and Chinese samples show that acquaintance recommendation, autonomy, relatedness, and technology self-efficacy are significantly related with the travel information acquisition and travel intention. In this study, smartPLS, which is widely used in social science, was used. PLS is a useful analytical tool for determining causality between variables. The present study will make practical contributions by enhancing the accuracy of travel recommendation services from the perspective of technology convergence. The results of this study are expected to provide guidelines for travel-related companies to develop personalization and customization services through big data and artificial intelligence techniques when they want to design travel recommendation systems. | Li, Guozhong; Seo, Joung-Hae; Park, Eun-Mi | Kunming Univ Sci & Technol, Dept MSIS, 68 Wenchang Rd,121 St, Kunming 650093, Yunnan, Peoples R China; Kyungpook Natl Univ, Sch Business, 80 Daehakro, Daegu 41566, South Korea | 56706642900; 57020497400; 56352305900 | issack38317@naver.com; | PERSONAL AND UBIQUITOUS COMPUTING | 1617-4909 | 1617-4917 | 26 | 2 | 0.23 | 2025-06-25 | 1 | 3 | autonomy; relatedness; travel intention; convergence | WORD-OF-MOUTH; SELF-EFFICACY; INTENTION; STUDENTS; AUTONOMY | autonomy; convergence; relatedness; travel intention | Artificial intelligence; Analytical tool; Artificial intelligence techniques; Customization services; Influential factors; Information searching; Personalizations; Technology convergence; Travel information; Smartphones | English | 2022 | 2022-04 | 10.1007/s00779-020-01473-5 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | Factors Influencing Entrepreneurial Intention: Focusing on Individuals’ Knowledge Exploration and Exploitation Activities | With rapid changes in industrial environments, the role of start-ups and their initial attempts toward the market are regarded as critical initiates. To increase the number of young start-up entrepreneurs, it is important to understand the relationship between entrepreneurial intention and its antecedents. Drawing on the organizational learning theory, we adopt the concept of exploration and exploitation as mediating roles of entrepreneurial intention as individual-level perspectives. Additionally, we consider innovativeness, self-efficacy, and internal locus of control as antecedents of two learning activities. The results indicate that each learning activity successfully supports the entrepreneurial intention, which requires a complex decision-making process and long-term efforts. This research discusses practical implications and guidelines for entrepreneurship education programs further. © 2022 by the authors. | Lee, Saerom; Kang, Min-Jeong; Kim, Byung-Keun | School of Business Administration, Kyungpook National University, Daegu, 41566, South Korea; BK21 Business Education Research Center, Korea University, Seoul, 02841, South Korea; School of Industrial Management, Korea University of Technology and Education, Cheonan, 31253, South Korea | 56023428700; 57904748100; 55972264000 | b.kim@koreatech.ac.kr; | Journal of Open Innovation: Technology, Market, and Complexity | 2199-8531 | 8 | 3 | 4.25 | 2025-06-25 | 29 | entrepreneurial intention; exploitation; exploration; innovativeness; internal locus of control; organizational learning; self-efficacy; young start-up entrepreneur | English | Final | 2022 | 10.3390/joitmc8030165 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Factors influencing quality of life in caregivers of adolescents with developmental disabilities | Objectives: Caring for adolescents with developmental disabilities (DD) is stressful and challenging, and mothers usually provide care for these children in Korea. This study aimed to identify factors influencing quality of life (QoL) in mothers of adolescents with DD. Methods: A predictive design was used. Data were collected from a web-based survey administered to a convenience sample of 154 mothers of adolescents with DD from October to November 2020. Data were analyzed using the t-test, analysis of variance, Pearson correlation coefficients, and multiple regression. Results: Perceived health, depression, and family strength were significantly correlated with QoL. Multiple regression showed that family strength, perceived health, depression, and monthly household income influenced the participants' QoL, and these factors accounted for 69.2% of variance in QoL. Family strength was the factor most strongly affecting QoL (beta=0.39). Conclusion: The study results indicate that health professionals and policy-makers need to pay attention to the overall QoL and physical and psychological health of mothers of adolescents with DD. Since our findings raise the importance of family strength in the QoL of this population, programs to improve family strength need to be implemented and strengthened. Interventions to improve perceived health and decrease depression should be applied, and knowledge on adolescent characteristics and changes should be delivered to caregivers when providing education and consultations. The findings will be helpful for developing educational and counseling programs for this population. | Joung, Joung Woo | Kyungpook Natl Univ, Res Inst Nursing Sci, 680 Gukchabosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Coll Nursing, 680 Gukchabosang Ro, Daegu 41944, South Korea | 56319847900 | godblessed@knu.ac.kr; | OSONG PUBLIC HEALTH AND RESEARCH PERSPECTIVES | OSONG PUBLIC HEALTH | 2210-9099 | 2233-6052 | 13 | 4 | ESCI | PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 4.3 | 0 | 2025-06-25 | 0 | 0 | Adolescent; Caregivers; Developmental disabilities; Quality of life | PERCEIVED HEALTH-STATUS; FAMILY FUNCTION; SELF-ESTEEM; CHILDREN; PARENTS; INDIVIDUALS; PROGRAM; MOTHERS | Adolescent; Caregivers; Developmental disabilities; Quality of life | adolescence; adolescent; adult; Article; care behavior; caregiver; controlled study; depression; developmental disorder; family relation; female; household income; human; major clinical study; male; middle aged; quality of life | English | 2022 | 2022-08 | 10.24171/j.phrp.2021.0158 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Fairness Enhancement of TCP Congestion Control Using Reinforcement Learning | In TCP congestion control research, the use of machine learning to solve the issue of unused link bandwidth and to improve performance, such as maximizing link utilization or minimizing latency, is steadily increasing. Among such approaches, the Deep Q Network (DQN)-based TCP congestion control algorithm improves the link utilization but suffers from performance degradation when a specific link bandwidth is exceeded. In addition, inter-protocol fairness with other TCP congestion control algorithms has not been verified. In this paper, on a NS3 simulator, we conducted the experiments to enhance the improvement of the DQN-based TCP congestion control algorithm v2 in single flow and an inter-protocol fairness when several flows share the same bottleneck link. Our results confirmed that the average throughput was improved, and our approach is fairer than existing congestion control algorithms. © 2022 IEEE. | Seo, Sang-Jin; Cho, You-Ze | Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea; Kyungpook National University, School of Electronic and Electrical Engineering, Daegu, South Korea | 57563304000; 7404469829 | chil258@knu.ac.kr; | 4th International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2022 - Proceedings | 2.46 | 2025-06-25 | 9 | Keywords Deep Q Network; TCP congestion control | Bandwidth; Reinforcement learning; Traffic congestion; Transmission control protocol; Improve performance; Keyword deep Q network; Link bandwidth; Link utilization; Network-based; Performance degradation; Protocol fairness; Reinforcement learnings; TCP congestion control; TCP congestion control algorithm; Deep learning | English | Final | 2022 | 10.1109/icaiic54071.2022.9722626 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Book chapter | Fatty Acid Composition in the Soybean Sprout | The value of soybean (Glycine max [L.] Merr) oil is determined by its fatty acid profile. Soybean oil has found excellent application in the food and health industries worldwide. The modification of fatty acid composition has become one of the major goals in soybean breeding programs. Soybean sprouts are used as dietary vegetables year-round in Korea, China, and Japan. They are an excellent source of protein, nutrients, and vitamins. Since soybean sprouts have high nutritional value and are simple to cultivate, there are significant demands for soybean sprouts in the market. In order to produce high-quality soybean sprouts, several factors, such as seed size, sprout characteristics, and health benefits need to be considered to improve fatty acid compositions. Herein, we will summarize the literature on soybean sprout components, fatty acid composition of soybean sprouts, changes in nutritional factors that occur during sprouting, and compare fatty acid compositions of soybean seeds and sprouts. In addition, we will review the changes in fatty acid compositions in soybean sprouts that occur under different environmental conditions during sprouting. Finally, we will discuss how fatty acid profiles in the ungerminated are important for achieving a similar fatty acid composition in the soybean sprout. The information reviewed will be useful for understanding the cultivation of soybean sprouts with modified fatty acid composition. © 2022 Taylor & Francis Group, LLC. | Jo, Hyun; Sultana, Syada Nizer; Song, Jong Tae; Lee, Jeong-Dong | Department of Applied Biosciences, Kyungpook National University, Daegu, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, South Korea; Department of Applied Biosciences, Kyungpook National University, Daegu, South Korea | 57194539358; 57366275700; 57797134000; 40462075100 | Phytochemicals in Soybeans: Bioactivity and Health Benefits | 0 | 2025-06-25 | 0 | English | Final | 2022 | 10.1201/9781003030294-21 | 바로가기 | 바로가기 | |||||||||||||||||||||
| ○ | ○ | Article | Fatty Liver Change in Korean Adults in a Systematic Social Distancing System Amid the COVID-19 Pandemic: A Multicenter Analysis | In response to the COVID-19 pandemic, the Korean government implemented policies including the systematic social distancing (SSD) system which started on 28 June 2020. The present study investigated the development and aggravation of fatty liver measured using ultrasonography during the transition period (from pre-SSD to SSD) compared to the fatty liver changes during the pre-SSD period. Changes in fatty liver and liver enzymes were assessed in different groups stratified by alcohol consumption. Our retrospective cohort analysis included 5668 participants who underwent health checkups at 13 university hospitals during the SSD period and two or more checkups before the SSD period. Fatty liver developed and aggravated more in the transition period (13.6% development and 12.0% aggravation) than in the pre-SSD period (10.8% development and 10.1% aggravation) in the alcohol consumption group. This finding was more prominent in women than in men. Abnormal alanine transaminase levels were more often developed in the transition period than in the pre-SSD period, especially in men (11.1% vs. 8.6% in each period). In conclusion, the SSD system may contribute to fatty liver changes in individuals who regularly consume alcohol. Further research of the post-pandemic period is needed to assess long-term changes in fatty liver disease. | Haam, Ji-Hee; Hur, Yang-Im; Kim, Young-Sang; Kim, Kyoung-Kon; Kang, Jee-Hyun; Ko, Hae-Jin; Cho, Yoon Jeong; Choi, Hye-In; Lee, Kyu Rae; Park, Jung Ha; Cho, Soo Hyun; Kim, Jong-Koo; Lee, Taesic; Seo, Myung-Jae; Yoon, Yeong Sook; Seo, Yoobin; Nam, Ga Eun; Kim, Sun Hyun | CHA Univ, Dept Family Med, CHA Bundang Med Ctr, Seongnam 13496, South Korea; CHA Univ, Chaum Life Ctr, Seoul 06062, South Korea; Gachon Univ, Dept Family Med, Coll Med, Gil Med Ctr, Incheon 21565, South Korea; Konyang Univ, Dept Family Med, Coll Med, Daejeon 35365, South Korea; Kyungpook Natl Univ Hosp, Dept Family Med, Daegu 41944, South Korea; Daegu Catholic Univ, Dept Family Med, Daegu 42472, South Korea; Jeju Natl Univ Hosp, Dept Family Med, Jeju 63241, South Korea; Chung Ang Univ Hosp, Dept Family Med, Coll Med, Seoul 06973, South Korea; Yonsei Univ, Dept Family Med, Wonju Coll Med, Wonju 26426, South Korea; Inje Univ, Dept Family Med, Ilsan Paik Hosp, Goyang 10380, South Korea; Wonkwang Univ, Dept Family Med, Sanbon Med Ctr, Gunpo 15865, South Korea; Korea Univ, Dept Family Med, Guro Hosp, Seoul 08308, South Korea; Catholic Kwandong Univ, Int St Marys Hosp, Dept Family Med, Coll Med, Incheon 22711, South Korea | ; Lee, Kyurae/J-8766-2019; Kim, Sun/C-2026-2011; Lee, Taesic/IQU-2971-2023; Nam, Ga Eun/AAU-6055-2020; Kim, Kyoung-Kon/GXV-1730-2022; Seo, Yoobin/GXH-8953-2022; Kim, Sun-Hyun/P-2263-2018; Kim, Sun/L-4239-2013; Cho, Soo Hyun/AAZ-4770-2021 | 56685485400; 52363748600; 57196173327; 8385516200; 56283070200; 54393415700; 55676577200; 57202001023; 24472041300; 57219448110; 57225917692; 35215202400; 57193750794; 57279475100; 8659033200; 57814053700; 49561817000; 56042294700 | zeroup@cha.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 16 | 0.36 | 2025-06-25 | 4 | 4 | COVID-19; systematic social distancing; fatty liver; liver enzyme; alcohol consumption | ALCOHOL-CONSUMPTION; GENDER-DIFFERENCES; METABOLIC SYNDROME; DISEASE; MANAGEMENT; FIBROSIS; IMPACT; GUIDELINES; ULTRASOUND | alcohol consumption; COVID-19; fatty liver; liver enzyme; systematic social distancing | Adult; COVID-19; Fatty Liver; Female; Humans; Male; Pandemics; Physical Distancing; Republic of Korea; Retrospective Studies; South Korea; alanine aminotransferase; alcohol consumption; COVID-19; digestive system; disease control; epidemic; governance approach; health policy; health status; pandemic; policy implementation; adult; age; alanine aminotransferase blood level; alcohol consumption; Article; clinical assessment; clinical feature; cohort analysis; comparative study; controlled study; coronavirus disease 2019; disease exacerbation; drinking behavior; echography; fatty liver; follow up; human; Korean (people); male; middle aged; multicenter study; pandemic; retrospective study; self report; social distancing; clinical trial; diagnostic imaging; fatty liver; female; pandemic; South Korea | English | 2022 | 2022-08 | 10.3390/ijerph191610444 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Proceedings Paper | Fault detection in PMSM by using indexed based methods | In general, permanent magnet synchronous motors (PMSM) require four main sensors (two current sensors, one position sensor, and a dc-link voltage sensor) for continuous performance. If a sudden fault occurs in any one or more sensors, the performance of the drive deteriorates and the system becomes unstable. The existing works are limited to fault detection of a single sensor. To this end, we analyze the performance of several indices for single and multi-fault sensor fault detection scenarios. The suitability of these indices for PMSM is analyzed. Simulation results are presented to demonstrate the pros and cons of various methods for fault detection. | Narzary, Daijiry; Veluvolu, Kalyana C. | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea | NARZARY, DAIJIRY/AIE-7187-2022; Veluvolu, Kalyana/C-6366-2011 | 57201854373; 8703318200 | narzary_daijy@knu.ac.kr;veluvolu@ee.knu.ac.kr; | 2022 IEEE 20TH INTERNATIONAL POWER ELECTRONICS AND MOTION CONTROL CONFERENCE, PEMC | 0 | 2025-06-25 | 0 | 0 | sensor fault detection; FDI; residuals analysis; permanent magnet synchronous motor; indices | DIAGNOSIS; MACHINE; DRIVES | FDI; indices; permanent magnet synchronous motor; residuals analysis; sensor fault detection | Permanent magnets; Synchronous motors; Current sensors; DC-link voltages; Faults detection; FDI; Index; Performance; Permanent Magnet Synchronous Motor; Position sensors; Residuals analysis; Sensor fault detection; Fault detection | English | 2022 | 2022 | 10.1109/pemc51159.2022.9962907 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Feature Analysis for Detecting Mobile Application Review Generated by AI-Based Language Model | Mobile applications can be easily downloaded and installed via markets. However, malware and malicious applications containing unwanted advertisements exist in these application markets. Therefore, smartphone users install applications with reference to the application review to avoid such malicious applications. An application review typically comprises contents for evaluation; however, a false review with a specific purpose can be included. Such false reviews are known as fake reviews, and they can be generated using artificial intelligence (AI)-based text-generating models. Recently, AI-based text-generating models have been developed rapidly and demonstrate high-quality generated texts. Herein, we analyze the features of fake reviews generated from Generative Pre-Training-2 (GPT-2), an AI-based text-generating model and create a model to detect those fake reviews. First, we collect a real human-written application review from Kaggle. Subsequently, we identify features of the fake review using natural language processing and statistical analysis. Next, we generate fake review detection models using five types of machine-learning models trained using identified features. In terms of the performances of the fake review detection models, we achieved average F1-scores of 0.738, 0.723, and 0.730 for the fake review, real review, and overall classifications, respectively. | Lee, Seung-Cheol; Jang, Yonghun; Park, Chang-Hyeon; Seo, Yeong-Seok | Yeungnam Univ, Dept Comp Engn, Gyongsan, South Korea; Univ Yeungnam, Comp Sci, Gyongsan, South Korea; Kyungpook Univ, Comp Stat, Daegu, South Korea; Republ Korea Adv Inst Sci & Technol KAIST, Comp Sci, Daejeon, South Korea | ; Seo, Yeong-Seok/AAF-2849-2019 | fatalist316@gmail.com;killerwise2@ynu.ac.kr;park@yu.ac.kr;ysseo@yu.ac.kr; | JOURNAL OF INFORMATION PROCESSING SYSTEMS | J INF PROCESS SYST | 1976-913X | 2092-805X | 18 | 5 | ESCI | COMPUTER SCIENCE, INFORMATION SYSTEMS | 2022 | 1.6 | 4 | Artificial Intelligence; Fake Review; GPT-2; Language Model; Machine Learning; Software Engineering | English | 2022 | 2022-10 | 10.3745/jips.02.0182 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Feeding Longer Frames for Efficient Video Denoising Model | Recently, deep video denoising networks have shown substantially higher denoising performance with considerably lower computing times. However, due to the various characteristics of video motion, such models may not be able to denoise long-term frames. In this paper, we propose a method that takes longer input frames and feeds them to the exist ing architecture. In particular, the proposed method can effectively extract temporal information from frames that are dependent on each other over a long period of time. To demonstrate the performance of the proposed method, we imple mented our method on the state-of-the-art video denoising model. Through the extensive experiments, the proposed method showed better performance in terms of quality metrics than the existing one, even with a higher noise level, resulting in considerably lower computing times. © 2022.
