| ○ | Proceedings Paper | Scrambling Technique of Instruction Power Consumption for Side-Channel Attack Protection | This paper proposed the technique to protect the embedded devices from the timing analysis attack using a sidechannel attack. Embedded devices have the advantage of excellent accessibility. However, because of the excellent accessibility, embedded devices are vulnerable to hardware attacks. In the case of the password matching function, the attacker can see the execution time of the function and infer which digits are matched monitoring the power consumption and using the timing analysis attack. In this paper, we proposed the clock scrambling method to hide the execution time of the instruction. It can help to protect embedded devices from the timing analysis attack by randomizing the execution time of the instruction. Our hardware model costs 2.56% additional area for clock scrambler, and costs on average 28% in execution time and 27% additional power consumption for scrambling power pattern. | Lee, Dongkyu; Kang, Myeongjin; Plesznik, Peter; Cho, Jeonghun; Park, Daejin | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | boltanut@knu.ac.kr; | 2020 INTERNATIONAL CONFERENCE ON ELECTRONICS, INFORMATION, AND COMMUNICATION (ICEIC) | 1 | English | 2020 | 2020 | 바로가기 | |||||||||||||||||||||||||

| ○ | ○ | Article | Screening Rice (Oryza sativa) Cultivars for Resistance to Bacterial Leaf Blight Disease | Bacterial Leaf Blight (BLB), caused by Xanthomonas oryzae pv. Oryzae (Xoo), is a devastating disease that affects the yield and quality of rice (Oryza sativa L.) produced throughout the world. However, resistant rice cultivars do exist, and utilizing them in regions impacted by BLB is an important tool in reducing crop loss. In this study, six rice cultivars widely grown in Ghana along with controls were phenotypically screened for resistance to Xoo strain K1 under greenhouse conditions. Phenotypic assessment identified the rice cultivar Popa as the most resistant Ghanaian phenotype. To investigate cultivars carrying Xanthomonas resistance alleles (Xa-R genes), five STS/SSR markers (RM-317, RM-224, RM-13, xa-13 prom and pTA248) respectively linked to Xa2, Xa4, xa5, xa13 and Xa21 were used to genotype selected cultivars. Our results revealed that Ghanaian cultivars, Tinsibe, AGRIC-1 and Krampa White, cant' Xa2; Kabre and Krampa White carry Xa4; and Popa and IRAT10 carry xa5. However, none of the 10 cultivars showed the presence of xa13 and Xa21. The O. sativa subsp. indica resistant control, Tetep, contained Xa2 and xa5, whereas the susceptible control, IR661, contained xa5. Quantitative real-time PCR (qRT) results of selected cultivars revealed variable expression profiles of OsWRKY45, OsPR10b, OsJAZ8 and OsPR1a in response to Xoo infection. Though one or more genes responsible for Xoo resistance were present in Ghanaian cultivars, most still exhibited a susceptible phenotype following Xoo infection, which indicates that these Xa genes identified primarily from East Asian germplasm that typically confer resistance are not the primary source of resistance in West African rice cultivars to the Xoo K1 strain.

| ○ | ○ | Proceedings Paper | Secure Backscatter Communications in Multi-Cell NOMA Networks: Enabling Link Security for Massive IoT Networks | Non-orthogonal multiple access (NOMA) and backscatter communications are considered to be promising technologies due to their applications in large-scale Internet-of-things (IoT) networks for ensuring low-powered and spectral efficient communication. However, massive connectivity of IoT devices may result in compromising the link security, resulting in information leakage to eavesdroppers. To solve this issue, we consider a multi-cell backscatter network where a base station (BS) in each cell communicates to cellular users using the power domain NOMA technique. A backscatter node in each cell also receives the superimposed signal from BS, utilizes this signal to modulate data and, then, retransmit it to nearby cellular user in the presence of multiple eavesdroppers. The eavesdroppers in the vicinity may try to overhear the transmission of the backscatter node due to the broadcast nature of the wireless network. Therefore, we investigate an optimization problem to maximize the secrecy rate of the NOMA-enabled multi-cell backscatter network. In particular, we optimize the reflection coefficient of the backscatter node in the presence of multiple eavesdroppers in each cell. The optimization problem is formulated as a convex problem that is subjected to the maximum reflection coefficient of the backscatter node. To obtain an optimal solution, we exploit Karush-Kuhn-Tucker conditions where the Lagrangian multipliers are updated by the sub-gradient method. We also present the secrecy maximization problem under traditional time division multiple access (TUNA) for the sake of comparison. Finally, the results are obtained using the Monte Carlo simulation which demonstrates that the proposed NOMA scheme significantly outperforms the traditional TDMA scheme. | Khan, Wali Ullah; Liu, Ju; Jameel, Furqan; Khan, Muhammad Toaha Raza; Ahmed, Syed Hassan; Janti, Riku | Shandong Univ, Sch Informat Sci & Engn, Qingdao 266237, Peoples R China; Aalto Univ, Dept Commun & Networking, Espoo 02150, Finland; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Georgia Southern Univ, Dept Comp Sci, Statesboro, GA 30460 USA | Jäntti, Riku/G-2270-2013; Khan, Waliullah/U-7723-2019; Shah, Syed Hassan/E-5058-2014; Khan, Turyalai/HPH-0061-2023; Jantti, Riku/G-2270-2013 | 57206847431; 57192101617; 57193333654; 57202044597; 55389144500; 56186204500 | IEEE INFOCOM 2020 - IEEE CONFERENCE ON COMPUTER COMMUNICATIONS WORKSHOPS (INFOCOM WKSHPS) | 2159-4228 | 6.6 | 2025-06-25 | 38 | 42 | Backscatter communication; Internet-of-things; non-orthogonal multiple access; secrecy rate; dual theory | Backscatter communication; Dual theory; Internet-of-things; Non-orthogonal multiple access; Secrecy rate | Backscattering; Cells; Cytology; Gradient methods; Internet of things; Lagrange multipliers; Low power electronics; Mobile telecommunication systems; Monte Carlo methods; Network security; Optimization; Reflection; Efficient communications; Karush Kuhn tucker condition; Lagrangian multipliers; Large scale Internet; Maximization problem; Optimization problems; Sub-gradient methods; Time division multiple accesses (TDMA); Time division multiple access | English | 2020 | 2020 | 10.1109/infocomwkshps50562.2020.9162938 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Conference paper | Segmented Polynomial Approximation for Controlled System Characteristic Estimation on Lightweight Edge Device | In a system that requires a fast response characteristic rather than an accurate response, the ability to respond quickly, even at the expense of accuracy, is beneficial to the system. In this paper, we propose the method that divides the data into several segments and estimates the linear equation of polynomial characteristic separately for each segment. As the smaller the size of segments, the reduced order of the polynomials to be estimated makes the smaller amount of calculation required. It minimizes the reduction in the accuracy of the estimated polynomial characteristic and completes the calculation faster than applying estimation to the entire data. The proposed method was implemented and evaluated on the target embedded board, and the result shows that the optimal segment size for the proposed polynomial approximation. © 2020 IEEE. | Kim, Minsung; Baek, Jongheon; Jung, Jiwoong; Kwon, Jisu; Park, Daejin | Kyungpook National University, School of Electronics Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea; Kyungpook National University, School of Electronics Engineering, Daegu, South Korea | 57221334399; 57221325939; 57221332549; 57215531728; 55463943600 | boltanut@knu.ac.kr; | 2020 IEEE International Conference on Consumer Electronics - Asia, ICCE-Asia 2020 | 0 | 2025-06-25 | 0 | Dynamic characteristic; Edge device; Embedded system; Polynomial approximation | Data reduction; Accurate response; Controlled system; Embedded boards; Fast response; Reduced order; Polynomial approximation | English | Final | 2020 | 10.1109/icce-asia49877.2020.9276901 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Selection of grasping target and control system of robotic prosthetic hand using images and deep learning | Robotic prosthetic hands are a device that helps to improve the quality of life for patients without hands. Recently, robotic prosthetic hands can perform various grasping patterns because of improvement of bioengineering and robotics. The research that automatically selects the appropriate operation according to the situation is important. Many previous studies have used EMG signals. However, EMG signals are difficult to generalize because EMG signals vary depending on the position of the muscle. In this study, we developed a system for controlling robotic prosthetic hands using images and deep learning to facilitate generalization. We also proposed a method for selecting a grasping target to be held in the image. These results will help to improve the quality of life of the robotic prosthetic hand user. © ICROS 2020. | Park, Haejune; An, Bohyeon; Baek, Junmin; Lee, Dongkyu; Kim, Changwon; Joo, Subin; Kwon, Ohwon; Kim, Min Young; Seo, Joonho | Medical Device Lab, Korea Institute of Machinery and Materials, South Korea, School of Electronics Engineering, Kyungpook National University, South Korea; Assistive Medical Robot Lab, Korea Institute of Machinery and Materials, South Korea; Medical Device Lab, Korea Institute of Machinery and Materials, South Korea; Medical Device Lab, Korea Institute of Machinery and Materials, South Korea; Assistive Medical Robot Lab, Korea Institute of Machinery and Materials, South Korea; Medical Device Lab, Korea Institute of Machinery and Materials, South Korea; Medical Device Lab, Korea Institute of Machinery and Materials, South Korea; School of Electronics Engineering, Kyungpook National University, South Korea; Medical Device Lab, Korea Institute of Machinery and Materials, South Korea | 57210446574; 57216877040; 57210450933; 8673376500; 57199972728; 57216872832; 57026875700; 56739349100; 35761296900 | jhseo@kimm.re.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 26 | 5 | 0.57 | 2025-06-25 | 9 | Deep learning; Grasping; Object detection; Robot control; Robotic prosthetic hand; Vision | Agricultural robots; Learning systems; Prosthetics; Robotics; EMG signal; Prosthetic hands; Quality of life; Deep learning | Korean | Final | 2020 | 10.5302/j.icros.2020.20.0018 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Article | Selective Deposition of Al2O3 on the Upper Side-Photoelectrode to Improve Dye-Sensitized Solar Cell Efficiency | Charge recombination at the photoelectrode/dye/electrolyte interface decreases the energy conversion efficiency of dye-sensitized solar cells (DSSCs). To suppress charge recombination at this interface in DSSCs, an aluminum oxide (Al2O3) film can be deposited as an insulating metal oxide layer on the photoelectrode to form an energy barrier. However, the Al2O3 energy barrier can also disturb the transport of injected electrons to the working electrode through the titanium dioxide (TiO2) photoelectrode. In this study, Al2O3 was selectively deposited as an insulating metal oxide layer on the upper side of a TiO2 photoelectrode, which has a high probability of charge recombination, using plasma-enhanced atomic layer deposition. Deposition of the Al2O3 layer by this method helped to minimize the transport rate deterioration of injected electrons. This resulted in an increase of the efficiency of DSSCs containing the Al2O3 layer by 42.3% compared with that of a reference DSSC without the insulating metal oxide layer. | Kang, Goru; Choi, Eunmi; An, Jong-Ki; Chung, Nak-Kwan; Kim, Jin-Tae; Yun, Ju-Young | Sungkyunkwan Univ, Sch Mech Engn, Suwon 2066, Gyeonggi, South Korea; Korea Res Inst Stand & Sci, Mat & Energy Measurement Ctr, Daejeon 34113, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Univ Sci & Technol, Sch Div Nano & Informat Technol, Daejeon 34113, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 1 | 3 | Dye-Sensitized Solar Cells; Atomic Layer Deposition; Plasma-Enhanced Atomic Layer Deposition; Selective Deposition | CHARGE RECOMBINATION; TIO2; ELECTROLYTE; PERFORMANCE; TRANSPORT; PLASMA | English | 2020 | 2020-01 | 10.1166/jnn.2020.17299 | 바로가기 | 바로가기 | ||||||||||||||||||

| ○ | ○ | Article | Severe Upper and Lower Tarsal Ectropion with Immunoglobulin G4-related Ophthalmic Disease | Purpose: To present the first case of severe upper and lower tarsal ectropion associated with immunoglobulin G4 (IgG4)-related ophthalmic disease. Case summary: A 37-year-old male presented with relapsed eyelid swelling and periocular inflammation in the left eye for 7 years. He had severe upper and lower tarsal ectropion and a thickened upper eyelid with prolapsed conjunctival fornix. Orbital computed tomography showed a poorly defined anterior orbital mass involving the lacrimal gland and upper and lower eyelids on the left eye. The severe upper and lower eyelid ectropion was corrected by a modified spindle procedure and lateral tarsal strip. Hard, ill-defined fibrotic tissue and a mass around the lateral upper tarsal plate were discovered that required excision of the mass and a biopsy. Hematologic and histopathologic findings of the orbital mass indicated IgG4-related ophthalmic disease with severe upper and lower ectropion caused by the disease. Conclusions: In cases of severe upper and lower eyelid ectropion caused by chronic inflammation, as seen in this case, not only eyelid tightening with excision of the causative mass but also a modified spindle procedure is required to prevent rotation of the eyelid. | Oh, Jun Ho; Son, Byeong Jae | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, Daegu, South Korea | 57216588714; 57197444337 | supersbj@hanmail.net; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 61 | 8 | ESCI | OPHTHALMOLOGY | 2020 | N/A | 0 | 2025-06-25 | 1 | 1 | Immunoglobulin G4-related ophthalmic disease; Modified spindle procedure; Upper and lower eyelid ectropion | DIAGNOSTIC-CRITERIA; EVERSION | Immunoglobulin G4-related ophthalmic disease; Lower eyelid ectropion; Modified spindle procedure; Upper | Korean | 2020 | 2020-08 | 10.3341/jkos.2020.61.8.944 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Shear behavior model on crack surface subjected to cyclic load | For nonlinear analysis of reinforced concrete members under multi-directional stress state, the Disturbed Stress Field Model (DSFM) has been developed from the Modified Compression Field Theory (MCFT) so that crack slip behavior can be rigorously considered in the analysis. In the DSFM, however, shear stress-slip behavior along a crack is considered only for monotonic loading condition; crack surface behavior under cyclic load cannot be properly considered. In this paper, based on the Basic Contact Density Model (BCDM), a simple model has been developed to consider shear stress-slip behavior along a crack under cyclic load. In spite of the simplification, it has been found that the proposed model reasonably predicted the shear behavior along a crack under cyclic load. In addition, using the proposed model, it was shown that crack slip behavior can be more rationally described for a reinforced concrete panel under cyclic load. This paper is expected to be useful for relevant studies on structural behavior of reinforced concrete under cyclic load. © 2020 by Korea Concrete Institute. | Lee, Seong-Cheol | School of Architecture, Civil, Environmental, and Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea | 35784449900 | seonglee@knu.ac.kr; | Journal of the Korea Concrete Institute | 1229-5515 | 32 | 3 | 0 | 2025-06-25 | 0 | Aggregate interlock; Crack; Shear; Slip | Korean | Final | 2020 | 10.4334/jkci.2020.32.3.259 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Significance and Associated Factors of Long-Term Sequelae in Patients after Acute COVID-19 Infection in Korea | Background: As the coronavirus disease 2019 (COVID-19) pandemic has progressed, there has been a growing awareness of the long-term impacts of the COVID-19 infection. However, until recently, there was no published study that investigated COVID-19-related sequelae and related factors for greater than six months from the onset of COVID-19 symptoms or the time of COVID-19 diagnosis in Korea. Materials and Methods: Online survey and statistical analysis were conducted by Kyungpook National University Hospital on 5,252 patients diagnosed as COVID-19 between February 18, 2020 and March 14, 2020. Responders aged between 16 and 70 years were included. Long-term sequelae were defined as persistent symptoms or signs ≥ 6 months after acute COVID-19 infection. The survey was conducted from September 8, 2020 to September 10, 2020. Clinical characteristics and self-reported clinical sequelae of the responders were analyzed to investigate the prevalence and factors associated with sequelae using descriptive and multivariate logistic regression analysis. Results: The median period from the date of the first symptom onset or COVID-19 diagnosis to the time of the survey was 195 (interquartile range [IQR] 191 - 200) days. The response rate was 17.1% (900 out of 5,252). The median age was 31 (IQR 24.0 - 47.0) years old, and 627 responders were female (69.7%). Regarding the disease severity, 29 (3.2%) were asymptomatic, 763 (84.8%) mild, 86 (9.6%) moderate, 17 (1.9%) severe, and 5 (0.6%) critical. In total, 591 (65.7%) responders suffered from COVID-19-related long-term sequelae and 78 (8.6%) responders were receiving outpatient treatment for COVID-19-related long-term sequelae. The most common symptoms identified during the isolation period were anosmia and ageusia at 44.5% and 43.5%, respectively. Fatigue was the most common long-term sequelae, accounting for 253 (26.2%) responders, followed by concentration difficulty, amnesia, cognitive dysfunction, anxiety, and depression, which accounted for over 20%. Female gender was identified as the factor associated with mental and psychological long-term sequelae (P<0.05). Conclusion: The results showed that the rate of COVID-19-related long-term sequelae was 65.7%. The most common long-term sequela was fatigue. The risk factor identified was female gender. It was found that the long-term sequelae had various manifestations, including mental and psychological aspects. To improve the care of COVID-19 recovered patients with COVID-19-related long-term sequelae, the participation of a comprehensive and an interdisciplinary group of researchers is required. isio Provisional Copyright © 2021 by The Korean Society of Infectious Diseases, Korean Society for Antimicrobial Therapy, and The Korean Society for AIDS Pr | Kim, Yoonjung; Kim, Shin-Woo; Chang, Hyun-Ha; Kwon, Ki Tae; Bae, Sohyun; Hwang, Soyoon | Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea; Division of Infectious Disease, Department of Internal Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea | 57203160508; 8710731500; 7407521688; 9733850500; 57219699506; 57203160675 | ksw2kms@knu.ac.kr; | Infection and Chemotherapy | INFECT CHEMOTHER | 2093-2340 | 2092-6448 | 53 | ESCI | INFECTIOUS DISEASES | 2020 | N/A | 1.95 | 2025-06-25 | 31 | Clinical sequelae; COVID-19; Long-term consequences; SARS-CoV-2; Sequelae | adolescent; adult; aged; ageusia; alopecia; amnesia; anosmia; anxiety; arthralgia; Article; chest tightness; cognitive defect; controlled study; coronavirus disease 2019; depression; diarrhea; disease severity; dizziness; dyspnea; fatigue; female; fever; gastrointestinal symptom; headache; health care utilization; hearing impairment; heart arrhythmia; heart palpitation; home quarantine; human; Korea; long term care; major clinical study; male; middle aged; myalgia; nausea; nose obstruction; outpatient; prevalence; priority journal; quarantine; questionnaire; rash; rhinorrhea; skin pruritus; social phobia; sore throat; thorax pain; tinnitus; vomiting | English | Final | 2020 | 10.3947/ic.2021.0022 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Silicon and Gibberellins: Synergistic Function in Harnessing ABA Signaling and Heat Stress Tolerance in Date Palm (Phoenix dactyliferaL.) | Date palm is one of the most economically vital fruit crops in North African and Middle East countries, including Oman. A controlled experiment was conducted to investigate the integrative effects of silicon (Si) and gibberellic acid (GA(3)) on date palm growth and heat stress. The exogenous application of Si and GA(3)significantly promoted plant growth attributes under heat stress (44 +/- 1 degrees C). The hormonal modulation (abscisic acid [ABA] and salicylic acid [SA]), antioxidant accumulation, and the expression of abiotic stress-related genes were evaluated. Interestingly, heat-induced oxidative stress was markedly reduced by the integrative effects of Si and GA(3)when compared to their sole application, with significant reductions in superoxide anions and lipid peroxidation. The reduction of oxidative stress was attributed to the enhancement of polyphenol oxidase, catalase, peroxidase, and ascorbate peroxidase activities as well as the upregulation of their synthesis related genes expression viz.GPX2,CAT,Cyt-Cu/Zn SOD, andglyceraldehyde3-phosphate dehydrogenasegene (GAPDH). The results showed the activation of heat shock factor related genes (especiallyHsfA3) during exogenous Si and GA(3)as compared to the control. Furthermore, the transcript accumulation of ABA signaling-related genes (PYL4,PYL8, andPYR1) were significantly reduced with the combined treatment of Si and GA(3), leading to reduced production of ABA and, subsequently, SA antagonism via its increased accumulation. These findings suggest that the combined application of Si and GA(3)facilitate plant growth and metabolic regulation, impart tolerance against stress, and offers novel stress alleviating strategies for a green revolution in sustainable food security. | Khan, Adil; Bilal, Saqib; Khan, Abdul Latif; Imran, Muhammad; Shahzad, Raheem; Al-Harrasi, Ahmed; Al-Rawahi, Ahmed; Al-Azhri, Masood; Mohanta, Tapan Kumar; Lee, In-Jung | Univ Nizwa, Nat & Med Sci Res Ctr, Nizwa 616, Oman; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Imam Abdulrahman Bin Faisal Univ, Basic & Appl Sci Res Ctr, POB 1982, Dammam 31441, Saudi Arabia; Imam Abdulrahman Bin Faisal Univ, Dept Biol, Coll Sci, POB 1982, Dammam 31441, Saudi Arabia; Agr Res Stn, Jemaah 616, Nizwa, Oman | Khan, Abdul/H-5910-2011; MOHANTA, TAPAN KUMAR/F-9907-2018; Imran, Muhammad/AFL-6590-2022; Khan, Adil/AAC-5160-2022; Ul-Hamid, Anwar/B-7297-2015; Shahzad, Raheem/AAG-8370-2019; Lee, In-Jung/GLS-0432-2022 | 57200917937; 57031617400; 26639372800; 58282433800; 56454250900; 6506093146; 7801308442; 57216917551; 58795818100; 16425830900 | adilsafi122333@gmail.com;saqib043@yahoo.com;ijlee@knu.ac.kr;imran.khan2324@gmail.com;raheem.shehzad@ymail.com;aharrasi@unizwa.edu.om;ahmedalrawahi2@unizwa.edu.om;moharab@yahoo.com;tapanmohanta@unizwa.edu.om;latifepm78@yahoo.co.uk; | PLANTS-BASEL | 2223-7747 | 9 | 5 | 5.84 | 2025-06-25 | 64 | 75 | silicon; heat stress; gibberellins; date palm; oxidative stress | ACID BIOSYNTHESIS; MECHANISMS; RESPONSES; DROUGHT; PLANTS | Date palm; Gibberellins; Heat stress; Oxidative stress; Silicon | English | 2020 | 2020-05 | 10.3390/plants9050620 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Simple fabrication of 3D micro container using PDMS stencil based on solvent evaporation | This paper describes a simple fabrication method of 3 D micro container using PDMS (polydimethylsiloxane) stencil by solvent evaporation. PDMS stencils were prepared by air knife system designed by our group. PLGA (poly (lactic-co-glycolic acid)), which is a bio polymer, was used as material of micro container. The size and geometry of micro container were easily controlled by that of PDMS stencil. The fabricated micro container could be sealed with aqueous alginate solution. Furthermore, feasibility of fabricated micro container as a cell container was inspected by culturing HepG2 (liver hepatocellular carcinoma) cell. © 17CBMS-0001. | Kim, C.M.; Lee, H.B.; Kim, J.U.; Cui, Y.L.; Kim, J.A.; Yoo, S.K.; Kim, G.M. | School of Mechanical Engineering, Kyungpook National University, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea; Medical Device Development Center, Osong Medical Innovation Foundation, South Korea; Medical Device Development Center, Osong Medical Innovation Foundation, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea | 59316640400; 57199749285; 57199753917; 57215009447; 57203509634; 57215009882; 55664733000 | gyuman.kim@knu.ac.kr; | 21st International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2017 | 0 | 2025-06-25 | 0 | Micro container; PDMS stencil; PLGA; Solvent evaporation | Containers; Evaporation; Microchannels; Silicones; Solvents; Air knives; Alginate solutions; Fabrication method; Hepatocellular carcinoma; PLGA; Poly lactic-co-glycolic acid; Solvent evaporation; Fabrication | English | Final | 2020 | 바로가기 | ||||||||||||||||||||
| ○ | Article | Simulation of High-Speed and Low-Power CMOS Binary Image Sensor Based on Gate/Body-Tied PMOSFET-Type Photodetector Using Double-Tail Comparator | In this paper, we propose a complementary metal-oxide semiconductor (CMOS) binary image sensor with a gate/body-tied (GBT) p-channel metal-oxide-semiconductor field-effect transistor (PMOSFET)-type photodetector using a double-tail comparator for high-speed and low-power operations. The GBT photodetector is based on a PMOSFET tied with a floating gate (n+ polysilicon) and a body that amplifies the photocurrent generated by incident light. A double-tail comparator compares an input signal with a reference voltage and returns the output signal as either 0 or 1. The signal processing speed and power consumption of a double-tail comparator are superior over those of conventional comparator. Further, the use of a double-sampling circuit reduces the standard deviation of the output voltages. Therefore, the proposed CMOS binary image sensor using a double-tail comparator might have advantages, such as low power consumption and high signal processing speed. The proposed CMOS binary image sensor is designed and simulated using the standard 0.18 μm CMOS process. © 2020, Korean Sensors Society.

| ○ | ○ | Proceedings Paper | Simulation studies for neutron and muon-induced backgrounds in AMoRE-II | The Advanced Mo-based Rare process Experiment (AMoRE) is an experiment to search for neutrino-less double beta decays of Mo100. The second phase of the experiment, AMoRE-II, will be conducted with 200 kg of Mo100-containing crystals. To reach a sensitivity goal at 12-22 meV level in the effective neutrino mass, AMoRE-II is required to have no background at the region of interest [1]. Dominant sources of backgrounds are expected from environmental neutrons, cosmic muons, and muon secondaries. In this study, we perform simulations of the backgrounds from cosmic muon and environmental neutrons with the Geant4 framework [2]. Using those simulated background sources, we have examined the performance of muon veto counters, and shielding structures with polyethylene and additional materials containing hydrogen and boron. We found an optimal background estimation of ckky level of 10(-5) order of magnitude with "the best choice of the setup" which would be acceptable for the AMoRE-II experiment requirement. | Bae, H.
