| ○ | ○ | Article | Aldosterone-induced cardiac damage in primary aldosteronism depends on its subtypes | Objectives: This study compared cardiac function, morphology, and tissue characteristics between two common subtypes of primary aldosteronism (PA) using a 3T MR scanner. Design: A retrospective, single-center, observational study. Methods: We retrospectively reviewed 143 consecutive patients with PA, who underwent both adrenal venous sampling and cardiac magnetic resonance. We acquired cine, late gadolinium enhancement, and pre- and postcontrast myocardial T1-mapping images. Results: PA was diagnosed as unilateral aldosterone-producing adenoma (APA) in 70 patients and bilateral hyperaldosteronism (BHA) in 73. The APA group showed significantly higher plasma aldosterone concentration (PAC) and aldosterone to renin rate (ARR) than the BHA group. After controlling for age, sex, antihypertensive drugs, systolic and diastolic blood pressure, and disease duration, the parameters independently associated with APA were: left ventricular end-diastolic volume index (EDVI: adjusted odds ratio (aOR) = 1.06 (95% CI: 1.030-1.096), P < 0.01), end-systolic volume index (ESVI: 1.06 (1.017-1.113), P < 0.01), stroke index (SI: 1.07 (1.020-1.121), P < 0.01), cardiac index (CI: 1.001 (1.000-1.001), P < 0.01), and native T1 (1.01 (1.000-1.019), P = 0.038). Weak positive correlations were found between PAC and EDVI (R = 0.28, P < 0.01), ESVI (0.26, P < 0.01), and SI (0.18, P = 0.03); and between ARR and EDVI (0.25, P < 0.01), ESVI (0.24, P < 0.01), and native T1 ( 0.17, P = 0.047). Conclusions: APA is associated with greater LV volumetric parameters and higher native T1 values, suggesting a higher risk of volume overload and myocardial damage. | Higuchi, Satoshi; Ota, Hideki; Tezuka, Yuta; Seiji, Kazumasa; Takagi, Hidenobu; Lee, Jongmin; Lee, Yi-Wei; Omata, Kei; Ono, Yoshikiyo; Morimoto, Ryo; Kudo, Masataka; Satoh, Fumitoshi; Takase, Kei | Tohoku Univ Hosp, Dept Diagnost Radiol, Sendai, Miyagi, Japan; Tohoku Univ, Dept Adv MRI Collaborat Res, Grad Sch Med, Sendai, Miyagi, Japan; Tohoku Univ Hosp, Dept Med, Div Nephrol Endocrinol & Vasc Med, Sendai, Miyagi, Japan; Tohoku Univ, Grad Sch Med, Div Clin Hypertens Endocrinol & Metab, Sendai, Miyagi, Japan; Univ British Columbia, Dept Radiol, Vancouver, BC, Canada; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kaohsiung Chang Gung Mem Hosp, Dept Radiol, Kaohsiung, Taiwan; Chang Gung Univ, Coll Med, Kaohsiung, Taiwan | ; Tezuka, Yuta/GZN-1703-2022; Takagi, Hidenobu/O-6166-2019; Ota, Hideki/A-3717-2012 | 57220204094; 14523314500; 56879861800; 22942323300; 56924327900; 55689919700; 36816140500; 56328540500; 50462088900; 23668547100; 36680357600; 7005717782; 7201509194 | h-ota@rad.med.tohoku.ac.jp; | ENDOCRINE CONNECTIONS | 2049-3614 | 10 | 1 | 0.18 | 2025-07-30 | 3 | 2 | aldosterone-induced cardiac damage; aldosterone-producing adenoma; bilateral hyperaldosteronism; cardiac magnetic resonance | HYPERTENSION; HEART; PREVALENCE; MORTALITY; FIBROSIS | aldosterone-induced cardiac damage; Aldosterone-producing adenoma; Bilateral hyperaldosteronism; Cardiac magnetic resonance | aldosterone; aldosterone antagonist; alpha adrenergic receptor blocking agent; angiotensin receptor antagonist; beta adrenergic receptor blocking agent; calcium channel blocking agent; captopril; corticotropin; dipeptidyl carboxypeptidase inhibitor; diuretic agent; furosemide; gadobutrol; gadolinium; hydrocortisone; metadrenalin; spironolactone; tetracosactide; adrenalectomy; adult; aged; Article; bilateral hyperaldosteronism; cardiac index; cardiomyopathy; cardiovascular magnetic resonance; congenital heart disease; diastolic blood pressure; disease duration; female; glomerulus filtration rate; heart arrhythmia; heart failure; heart function; heart injury; heart left ventricle enddiastolic volume; heart stroke volume; hematocrit; human; human tissue; hyperaldosteronism; hypertension; ischemic heart disease; kidney failure; major clinical study; male; mass spectrometry; mean arterial pressure; observational study; plasma renin activity; protein blood level; pulmonary valve atresia; pulse rate; radiofrequency ablation; renin angiotensin aldosterone system; retrospective study; stroke risk score; systolic blood pressure | English | 2021 | 2021-01 | 10.1530/ec-20-0504 | 바로가기 | 바로가기 | 바로가기 | |||||||||

| ○ | Book chapter | Alternative head-preserving procedure for osteonecrosis of the femoral head: Tissue engineering, future perspective | Osteonecrosis of the femoral head is the death of the cellular portion of the bone, with subsequent structural changes, leading to progressive collapse of the femoral head followed by degenerative arthritis of the hip joint and artificial joint replacement. Preservation of own femoral head instead of artificial implants especially in young patients with large involvement of head is the ideal goal. Vascularized bone grafting and transtrochanteric osteotomy had favorable results after long-term follow-up in lesions of medium to large size, weight-bearing portion located, and pre-collapsed necrosis. However, these procedures require very-high-demanding techniques, long operation time, and long-term rehabilitation period associated with unpredictable results and high rates of complications. We introduce a new tissue engineering technique using ex vivo culture-expanded bone marrow-derived stem cell seeding in calcium metaphosphate beads as an alternative minimal invasive procedure instead of technically challenging technique in challenging cases of osteonecrosis. © Springer Nature Switzerland AG 2021. | Kim, Shin-Yoon | Department of Orthopedic Surgery, School of Medicine, Kyungpook National University Hospital, Daegu, South Korea | 26663842900 | syukim@knu.ac.kr; | Advances in Specialist Hip Surgery | 0 | 2025-07-30 | 0 | Osteonecrosis; Stem cells; Tissue engineering | English | Final | 2021 | 10.1007/978-3-030-61830-8_12 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | ○ | Article | An algorithmic approach for performance tuning of a relational database system using dynamic SGA parameters | In twenty-first century, spatial database are becoming complex in nature due to the diversity of resources to generate and collect these datasets. Efficient query handing and high performance is the key requirement for success for the expert systems (like GIS) using these spatial databases. However, relational database management systems (RDBMS) used for storing spatial datasets are struggling for auto-tuning, self-diagnosis and self-healing. To overcome these challenges for spatial database and RDBMS, we have identified 250 plus dynamic parameters, which are responsible for managing SGA (system global area) of a running instance of any RDBMS. These parameters can be controlled at runtime and allocation and deallocation of memory to the various components of SGA can be managed by changing the values of these parameters. In this research work, the data is collected related to the system parameters and the resources utilized by the system. The collected data is automatically analyzed to find the relation between parameters and resources. Based upon the relations (direct or inverse) the decision will be taken by the developed utility to enhance overall system performance. In this work a framework, related algorithms, and utility tool to perform above-said steps for improving performance are designed and implemented. This research work will help to get fast and efficient handling of spatial datasets, which will directly affect the performance of expert system to take quick decisions. | Sharma, Hitesh Kumar; Choudhury, Tanupriya; Tomar, Ravi; Patni, J.

| ○ | Article | An alignment method for a TCP position of five-axis machine tools for ISO 10791-6 | ISO 10791-6 specifies test conditions, BK1 and BK2, including circularly interpolated motions by simultaneous control of two linear axes and a rotary/tilting axis, for five-axis machine tools with a tilting-rotary table. Eccentricities of measured motions are used to identify position-independent geometric errors of the rotary/tilting axis. However, time-consuming alignments of measurement devices are required to execute the circular motions due to large geometric errors of the tilting axis. In this paper, a simple method is proposed to align an initial position of a tool-center-point (TCP) relative to the actual tilting axis of five-axis machine tools for application of ISO 10791-6. A ball at the tool nose with an extension fixture, supplied commercially by a double ball-bar manufacturer, is used to measure positional deviations of a ball on workpiece table at 90° command angle of a tilting axis. An alignment error of a TCP is identified simply by using a geometric relationship of the TCP and measured deviations. Then, identified alignment errors are used to calculate initial position of a TCP for fine measurements of position-independent geometric errors specified in ISO 10791-6. The proposed method is applied to a five-axis machine tool and verified experimentally.

| ○ | Article | An analysis of land price changes after urban regeneration project in the local city downtown-focusing on gusan modern historical landscape area, daegu bangchun market·kim-kwangsuk-gil, and jeonju hanok village | Various urban regeneration projects implemented so far have had a positive effect of rediscovering local assets and revitalizing urban space. However, the value of real estate in the region has risen sharply, and the side effects of local members being transferred are also accompanied. It is especially serious in local cities that do not have their own driving force to revitalize the region. In this study, the trend of land prices changing after the implementation of urban regeneration projects was time-series for Gunsan, Daegu, and Jeonju, where gentrification occurred, among the urban regeneration areas where urban regeneration projects were implemented. After selecting the control area, which has similar physical environment to the research site and has a difference in whether urban regeneration projects are implemented or not, the pattern of land price changes from 2006 to 2020 was compared and analyzed through the DID analysis method. As a result of the study, there was a difference in the trend of changing the DID coefficient values in each region, but the land price changed over four stages in all three regions in common. It showed a pattern of falling land prices due to the declining regional characteristics before the project implementation, gradual or rapid rise in land prices due to the implementation of urban regeneration projects, amplification of changes, and continuous increase or decrease. It was also seen that the DID coefficient value showed a greater degree of change after the maximum value was displayed. In other words, it may be determined that the implementation of urban regeneration projects has a strong impact on the land price of the relevant area. Therefore, in order to strengthen the net function of urban regeneration projects and reduce the adverse effects, it is necessary to proactively respond to changes in the characteristics and environment of the target site based on step-by-step land price changes. © 2021 Architectural Institute of Korea. | Jang, Rebecca; Yoon, Cheol-Jae | Department of Architecture, Kyungpook National University, South Korea; Department of Architecture, Kyungpook National University, South Korea | 57223389119; 55939098800 | ironash@knu.ac.kr; | Journal of the Architectural Institute of Korea | 2733-6239 | 37 | 4 | 0.28 | 2025-07-30 | 3 | Changes in Land Price; Difference-in-Differences(DID); Gentrification; Real Transaction Land Price; Urban Regeneration | Korean | Final | 2021 | 10.5659/jaik.2021.37.4.193 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | An earthquake alert system based on a collaborative approach using smart devices | Recently, mobile devices such as smartphones and IoT devices have been successfully used for detecting earthquakes using their built-in accelerometers. To utilize such devices as a seismic sensor, there are two approaches including a standalone or a client-server approach. The client-server approach is more accurate than the stand-alone approach but requires high-performance servers and network infrastructures to process acceleration data captured from many client devices. In the standalone approach, straightforward earthquake detection algorithms can be easily implemented on less powerful mobile devices, but there is a possibility of false alarms. To address this limitation, in this paper, we present a collaborative approach that detects an earthquake using multiple smartphones located in a near area so as to improve the earthquake detection ability of the standalone approach without system and network infrastructures. In our approach, smartphones located in a near area construct a seismic network to detect earthquakes together and then wait for any shakings caused by human activities, mechanical vibrations, earthquakes, etc. When a smartphone detects an earthquake like motion using an earthquake detection algorithm based on a simple neural network, it broadcasts the detection result to nearby smartphones in a multi-hop manner. Upon receipt of the detection results from nearby smartphones, each smartphone participating in the seismic network performs a decision-making process and confirms an earthquake and then instantiates an alert. The experimental results show the effectiveness of the proposed approach, so we believe that our approach can be effectively used in high seismic countries that lack an earthquake early warning system (EEWS). | Khan, Irshad; Pandey, Manish; Kwon, Young-Woo | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | ; Pandey, Manish/J-6825-2019; Kwon, Young-Woo/HGE-6607-2022; Khan, Irshad/AAN-8522-2020 | 36166674500; 57239896800; 57208480210 | irshad.cs@knu.ac.kr;manish@knu.ac.kr;ywkwon@knu.ac.kr; | 2021 IEEE/ACM 8TH INTERNATIONAL CONFERENCE ON MOBILE SOFTWARE ENGINEERING AND SYSTEMS (MOBILESOFT 2021) | 1.32 | 2025-07-30 | 6 | 7 | smartphone; seismic network; accelerometer; machine learning; earthquake early warning system | accelerometer; earthquake early warning system; machine learning; seismic network; smartphone | Decision making; Signal detection; Smartphones; Software engineering; Vibrations (mechanical); Collaborative approach; Decision making process; Earthquake detection; Earthquake early warning systems; Human activities; Network infrastructure; Process acceleration; Seismic networks; Earthquakes | English | 2021 | 2021 | 10.1109/mobilesoft52590.2021.00014 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | ○ | Proceedings Paper | An Energy Efficient Sensor Duty Cycling for Smart Home Networks | Wireless Sensor Networks (WSN) applications are envisioned in various smart environments such as smart homes, smart cities, e-health, etc. Similarly, in future smart homes, an extensive sensor deployment would be required to control various home resident activities. However, deploying many sensors and operate them continuously requires a high amount of electrical energy. Therefore, in this paper, we presented a solution to prolong the sensors' battery life by assigning the pre-detected slots to the sensors using Bayesian Network (BN). Among the rest of the Idle Sensors (IS), a Watch Sensor (WS) is selected to detect the upcoming activities and activate the rest of the closely related sensors to the WS. The similarities between IS sensors are modeled using the Earth Mover's Distance (EMD) approach. Finally, an extensive set of simulations is performed in a smart home scenario to test the proposed scheme's performance. The simulation results show that the proposed approach significantly enhances the sensors' battery lifetime by scheduling the sensors' operational time to detect smart home resident activities. | Khan, Murad; Seo, Junho; Kim, Dongkyun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | Khan, Turyalai/HPH-0061-2023 | 56151971600; 57208740581; 35753648800 | mkhan@knu.ac.kr;jhseo@knu.ac.kr;dongkyun@knu.ac.kr; | 3RD INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE IN INFORMATION AND COMMUNICATION (IEEE ICAIIC 2021) | 0.39 | 2025-07-30 | 1 | 2 | Sensor Duty Cycling; Bayesian Networks; Earth Mover's Distance; Smart Homes | Bayesian Networks; Earth Mover's Distance; Sensor Duty Cycling; Smart Homes | Ambient intelligence; Artificial intelligence; Automation; Bayesian networks; Energy efficiency; Intelligent buildings; Personal communication systems; Secondary batteries; Wireless sensor networks; Battery life; Battery lifetime; Duty-cycling; Earth Mover's distance; Electrical energy; Energy efficient; Sensor deployment; Smart environment; Home networks | English | 2021 | 2021 | 10.1109/icaiic51459.2021.9415223 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Proceedings Paper | An Exploratory Study of the Participation in the Sharing Economy: What are the Influencing Variables? | The following is an exploratory study undertaken to identify and validate the variables that affect an individual's decision to participate in the sharing economy. Six variables are tested; five as independent variables and one as a moderator variable. The five are self-technological aptness, self-norm, attitude toward the sharing economy, desire to access a bigger market, and attitude toward environmental friendliness, while the moderator variable is economic benefit. Regarding data: 1000 promiscuously recruited individuals were asked and 479 individuals completed the survey out of which 466 individuals' responses are used for the data analysis. The self-determination theory provides the basis for the theoretical framework and hypothesis development. The result revealed that all variables showed a statistically significant relationship, except for the self-technologically aptness variable. Moreover, the moderating economic benefit variable exhibited a significant moderation effect on all the variables except in the case of self-technological aptness. Ultimately, this study provides a deeper understanding of those variables and their effect on the participants. Additionally, it presents opportunities for further research in this area. A full and complete report is expected later. | Choi, Stephen; Kim, Sang Hyun | Calif State Univ Fresno, Craig Sch Business, Dept Informat Syst & Decis Sci, Fresno, CA 93740 USA; Kyungpook Natl Univ, Sch Business Adm, Daegu, South Korea | choi@csufresno.edu;ksh@knu.ac.kr; | PROCEEDINGS OF THE 54TH ANNUAL HAWAII INTERNATIONAL CONFERENCE ON SYSTEM SCIENCES | 0 | English | 2021 | 2021 | 바로가기 | |||||||||||||||||||||||||

| ○ | ○ | Proceedings Paper | An Generational SDE based Indicator for Multi and Many-objective optimization | Recently, the study of designing multi-objective evolutionary algorithms (MOEAs) to solve multi and many-objective optimization has received lot of recognition. In this paper, we have proposed an indicator based MOEA (I-gSDE-MOEA) in which the information from the shift based density estimation is utilized to a greater extent. In the past, the shift based density estimation (SDE) is employed in conjunction with the other indicators and metrics. However, in this work, we employ the indicator based on SDE solely to approximate the Pareto front. The indicator proposed in this paper is adaptively controlled over the generations. The performance of the proposed I-gsDE-MOEA is evaluated by performing experiments on 14 benchmark problems and 7 real-world problems. The experimental results demonstrate that the proposed I-gsDE-MOEA exhibits better performance in comparison with the state-of-art algorithms. | Yusupov, Jamshid; Palakonda, Vikas; Ghorbanpour, Samira; Mallipeddi, Rammohan; Veluvolu, Kalyana Chakravarthy | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 702701, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Sch Elect Engn, Daegu, South Korea | Mallipeddi, Rammohan/AAL-5306-2020; Veluvolu, Kalyana/C-6366-2011 | 57222517053; 57193028485; 57207109590; 25639919900; 8703318200 | iamshid96se@gmail.com;vikas.11475@gmail.com;samira.ghorbanpour@gmail.com;mallipeddi.ram@gmail.com;veluvolu@ee.knu.ac.kr; | 3RD INTERNATIONAL CONFERENCE ON ARTIFICIAL INTELLIGENCE IN INFORMATION AND COMMUNICATION (IEEE ICAIIC 2021) | 0 | 2025-07-30 | 0 | 0 | Multi-objective optimization; Many-objective optimization; Evolutionary algorithms; Shift density based estimation | MULTIOBJECTIVE EVOLUTIONARY ALGORITHM; DECOMPOSITION | Evolutionary algorithms; Many-objective optimization; Multi-objective optimization; Shift density based estimation | Benchmarking; Evolutionary algorithms; Bench-mark problems; Density estimation; Indicators and metrics; Many-objective optimizations; Multi objective evolutionary algorithms; Pareto front; Real-world problem; Artificial intelligence | English | 2021 | 2021 | 10.1109/icaiic51459.2021.9415230 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||

| ○ | Book chapter | An online ANFIS-PF hybrid RUL prediction model with an application to gearbox | Avoiding unexpected and costly repairs for mechanical systems, specially wind turbines, brought up the science of prediction named Prognostics and Health management. This technique calculates the remaining useful life, and consequently, gives the opportunity to preserve normal performances of rotary machines. In this paper, an intelligent online data driven PHM method has introduced and applied to the experimental run-to-failure data. Firstly, a reduction gearbox test rig run series of experiments under specific speed and load levels to create a set of vibrating degradation data. Extracted Cumulative indicators are then concatenated to form a health index. Afterwards, a hybrid algorithm of Adaptive Neuro Fuzzy Inference System and Particle Filtering is built to evaluate the health index signal. ANFIS based on the auto-encoder hypothesis can model the degradation trend for prediction. Then, particle filtering is carried out for a-step-ahead behavior prediction. The performance of the result demonstrate that ANFIS-PF can successfully predict the degradation behavior with 95% confidence boundary. © 2021 Taylor & Francis Group, London. | Govahianjahromi, A.; Lee, D.; Mechefske, C.K. | Department of Electronics Engineering, Kyungpook National University, Daegu, South Korea; Department of Electronics Engineering, Kyungpook National University, Daegu, South Korea; Department of Mechanical and Materials Engineering, Queen’s University, Kingston, Canada | 57300616800; 55698910600; 7003908294 | Proceedings in Marine Technology and Ocean Engineering | 2638-647X | 2021 | 0 | 2025-07-30 | 0 | Forecasting; Fuzzy neural networks; Fuzzy systems; Gears; Health; Monte Carlo methods; Data driven; Health indices; Mechanical systems; Online data; Particle Filtering; Performance; Prediction modelling; Prognostic and health management; Remaining useful lives; Rotary machine; Fuzzy inference | English | Final | 2021 | 10.1201/9781003134572-57 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Conference paper | An Optimal Design Methodology of Ternary Logic in Iso-device Ternary CMOS | Studies report the possibility of the end of scaling, which is the key engine that has led the era of binary computers. Ternary computing is reported to have one of the highest potential to replace binary computers in the near future. Regarding this forecast, ternary CMOS (T-CMOS) is a device said to be a great candidate. However, research on actual circuit design must follow to verify its advantages fully. Thus, this paper studies the methodologies to design actual ternary logic based on T-CM OS devices. On top of the various novel ternary logic cells that we design, we propose an optimization technique to design arbitrary ternary logic with a minimum number of T-CMOS devices. Enlightening the usefulness of T-CMOS, we implemented a balanced ternary adder using only 68 transistors. Comparing between iso-device designs, we highlight that our ternary adder uses -30.6% fewer transistors than the most compact ternary adder currently-developed. © 2021 IEEE. | Ko, Jonghyun; Park, Kwanwoo; Yong, Suhyeong; Jeong, Taegam; Kim, Tae Hak; Song, Taigon | School of Electronic and Electrical 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; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea; School of Electronic and Electrical Engineering, Kyungpook National University (KNU), Daegu, 41566, South Korea | 59809554200; 57226887727; 57226882767; 57226890394; 57225038681; 36005021000 | Proceedings of The International Symposium on Multiple-Valued Logic | 0195-623X | 2021-May | 2.81 | 2025-07-30 | 9 | T-CMOS; ternary adder; ternary logic | Adders; CMOS integrated circuits; Integrated circuit design; Logic devices; Many valued logics; Circuit designs; CMOS devices; Device design; Optimal design; Optimization techniques; Ternary logic; Computer circuits | English | Final | 2021 | 10.1109/ismvl51352.2021.00040 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Proceedings Paper | An Optimized Standard Cell Design Methodology Targeting Low Parasitics and Small Area for Complementary FETs (CFETs) | The Complementary FET (CFET) is known to be a potential device to continue the feature size scaling. However, studies forecast that increased parasitic RC neutralizes the area reduction advantage that CFETs can provide. In this paper, (1) we report that RC increase by CFETs is not that significant (only +4.25% compared to 5 track FinFET INV), and (2) propose a design methodology that optimizes the parasitics of CFET standard cells to make this happen. Our methodology shows improvements in parasitics by up to 8.15% for capacitance and 32.73% for resistance when comparing the two types of CFET structures. | Park, Eunbin; Song, Taigon | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea | 57424580800; 36005021000 | milky0627@knu.ac.kr;tsong@knu.ac.kr; | 18TH INTERNATIONAL SOC DESIGN CONFERENCE 2021 (ISOCC 2021) | 2163-9612 | 0.79 | 2025-07-30 | 5 | 5 | CFET; standard cells; parasitics; beyond N3 | beyond N3; CFET; parasitics; standard cells | Beyond n3; Complementary FET; Design Methodology; Feature sizes; Low-parasitic; Parasitics; Size-scaling; Small area; Standard cell design; Standard-cell | English | 2021 | 2021 | 10.1109/isocc53507.2021.9613922 | 바로가기 | 바로가기 | 바로가기 |
