| ○ | ○ | Proceedings Paper | On Model Matching Control of Input/State Asynchronous Sequential Machines With Constraint on the Initial State | Corrective control for model matching of input/state asynchronous sequential machines (ASMs) is discussed in this paper. The control objective is to design a corrective controller that makes the closed-loop system stably equivalent with a prescribed reference model. In particular, this study focuses on the constraint that the initial state of the controlled machine cannot be set to he equal to that of the model. To describe this constraint, the set of initial model mismatches is defined and a matrix expression quantifying the initial model mismatches is introduced. Based on the stable reachability of the controlled machine, the condition for the existence of an appropriate corrective controller and its design procedure are outlined in the framework of corrective control theory. | Jeon, Min-Seong; Yang, Jung-Min | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57208740903; 57208450551 | mymsjun@naver.com;jmyang@knu.ac.kr; | 2020 IEEE/SICE INTERNATIONAL SYMPOSIUM ON SYSTEM INTEGRATION (SII) | 2474-2317 | 0 | 2025-06-25 | 0 | 0 | Closed loop systems; Controllers; Electric machine theory; Sequential machines; Asynchronous sequential machines; Control objectives; Corrective control; Design procedure; Matrix expression; Model matching; Model matching control; Reference modeling; Electric machine control | English | 2020 | 2020 | 10.1109/sii46433.2020.9025966 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | ○ | Article | On the Representations of Finite Distributive Lattices | A simple but elegant result of Rival states that every sublattice L of a finite distributive lattice P can be constructed from P by removing a particular family I-L of its irreducible intervals. Applying this in the case that P is a product of a finite set C of chains, we get a one-to-one correspondence L bar right arrow D-P (L) between the sublattices of P and the preorders spanned by a canonical sublattice C-lozenge of P. We then show that L is a tight sublattice of the product of chains P if and only if D-P(L) is asymmetric. This yields a one-to-one correspondence between the tight sublattices of P and the posets spanned by its poset J (P) of non-zero join-irreducible elements. With this we recover and extend, among other classical results, the correspondence derived from results of Birkhoff and Dilworth, between the tight embeddings of a finite distributive lattice L into products of chains, and the chain decompositions of its poset J (L) of non-zero join-irreducible elements. | Siggers, Mark | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | 14519683600 | mhsiggers@knu.ac.kr; | KYUNGPOOK MATHEMATICAL JOURNAL | KYUNGPOOK MATH J | 1225-6951 | 0454-8124 | 60 | 1 | ESCI | MATHEMATICS | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | finite distributive lattice; representation; embedding; product of chains | Embedding; Finite distributive lattice; Product of chains; Representation | English | 2020 | 2020-03 | 10.5666/kmj.2020.60.1.1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | One hundred representative fungi in korea and their korean names | One hundred representative species of fungi in Korea were selected and their Korean names were proposed to increase interest in fungi among Korean people. This task was performed under the supervision of the Committee of Mycological Terms, under the Korean Society of Mycology. First, the committee established the criteria for selecting 100 representative species of fungi in Korea and then selected the candidate fungal species accordingly. To ensure the uniformity and stability of Korean fungal names, the principle of naming fungi in Korean was established, and the candidate Korean fungal names were presented accordingly. Finally, the candidate Korean fungal names were posted online to collect opinions of the members of the Korean Society of Mycology. The candidate Korean names of the plant pathogenic fungi and mushrooms were reviewed by the Korean Society of Plant Pathology and the Korean Society of Mushroom Science, respectively. After their opinions were considered, the Korean names for 100 representative fungi in Korea were finally determined.

| ○ | Article | Optimal Design of a Transitional Rotor Blade for Agricultural Unmanned Rotorcraft using SAS | Recently, the adoption of unmanned rotorcraft systems in agriculture has attracted increasing attention. The aim of this study is to investigate the optimal operating condition of hovering with the transition blades, progressively formed with two basic airfoils, and to select the optimal twist angle accordingly. Response surface regression process (Proc RSREG) of SAS was used as an effective tool in the optimization of the simulation results, using multiple reference frame methodology via ANSYS Fluent. As a multi-objective design, the torque was limited to 63 % of the available power (24 kW, 1,000 rpm) of the agricultural rotorcraft. From a stable design point of DP2 (GPA = 15 degrees, twist angle = -11.8 degrees) to a conservative design point of DP4 (GPA = 10 degrees, twist angle = -4.9 degrees), designs were selected. Then, the transitional blades were fabricated, and the payloads of 569.0 N and 539.6 N were evaluated, respectively. | Koo, Young Mo | Kyungpook Natl Univ, Sch Agr Civil & Bioind Engn, Daegu, South Korea | ymkoo@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS B | T KOR SOC MEC ENG B | 1226-4881 | 44 | 1 | ESCI | ENGINEERING, MECHANICAL | 2020 | N/A | 0 | Optimization; Unmanned Rotorcraft; Response Surface Regression; Transitional Rotor Blade; Twist Angle | HELICOPTER; OPTIMIZATION; CFD | Korean | 2020 | 2020-01 | 10.3795/ksme-b.2020.44.1.013 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Optimal production of 7, 10-epoxy-octadeca-7, 9-dienoic acid from 7, 10-dihydroxy-8(E)-octadecenoic acid by heat treatment | Furan fatty acids (F-acid) are known to have strong antioxidant properties, including radical scavenging activity, which play important roles in biological systems including humans. F-acids are widely distributed in most biological systems as trace components and their biosyntheses are complicated. Although several studies were reported on the chemical synthesis of various types of F-acids, it required complicated and multistep chemical reactions. Recently, a simple one-step heat treatment method was developed for the production of a novel furan fatty acid, 7,10-epoxy-octadeca-7,9-dienoic acid (7,10-EODA) from 7,10-dihydroxy-8(E)-octadecenoic acid (DOD). (Journal of Agricultural and Food Chemistry, 2011, 59, 8175-8179). In this report, we optimized reaction conditions for the efficient production of 7,10-EODA from DOD by heat treatment. Under optimal conditions tested, the maximum production yield of 7,10-EODA was 80% with incubation in hexane for at least 48 h at 85 degrees C or above. | Ellamar, Joel B.; Kim, In-Hwan; Hou, Ching T.; Kim, Hak-Ryul | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 702701, South Korea; Korea Univ, Grad Sch, Dept Publ Hlth Sci, Seoul, South Korea; ARS, Renewable Prod Technol Res Unit, Natl Ctr Agr Utilizat Res, USDA, Peoria, IL USA | Ellamar, Joel/AAV-4662-2021 | 45860997500; 47161438300; 7202210071; 57191717289 | hakrkim@knu.ac.kr; | BIOCATALYSIS AND AGRICULTURAL BIOTECHNOLOGY | BIOCATAL AGR BIOTECH | 1878-8181 | 24 | ESCI | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2020 | N/A | 0.08 | 2025-06-25 | 2 | 2 | Furan fatty acid; 7,10-Epoxy-octadeca-7,9-dienoic acid; Heat treatment; 7,10-Dihydroxy-8(E)-octadecenoic acid | FURAN FATTY-ACIDS; 7,10-EPOXYOCTADECA-7,9-DIENOIC ACID; LIPIDS | 7,10-Dihydroxy-8(E)-octadecenoic acid; 7,10-Epoxy-octadeca-7,9-dienoic acid; Furan fatty acid; Heat treatment | English | 2020 | 2020-03 | 10.1016/j.bcab.2020.101545 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Optimal red clover ethanolic extract by relative aggregated metric increases osteoblastic activity and nuclear factor kappa-B ligand gene expression in SaOS-2 cells | Age-related osteoporosis affects people of both genders at any age especially postmenopausal women. The manifestation of reduced bone strength leads to increased risk of bone fracture. Currently, many have sought for plant-based supplements for the management of bone health. Red clover (Trifolium pratense) contains phytoestrogenic isoflavones which are known to limit osteoclastic activity and reduce bone resorption. Our study aimed to optimize the condition for the preparation of red clover ethanolic extract to obtain highest yield while retaining the desired bioactivity. In this study, relative aggregated metric (RAM) was designed to ease the selection process of extraction formulation based on yield and SaOS-2 cell viability. The selected ethanolic red clover extract obtained from the optimum condition (RC-D) exerted high cell viability in SaOS-2 cells which is comparable to that of 17 beta -estradiol. RC-D also showed promising dose-dependent alkaline phosphatase activity in SaOS-2 cells. Besides, the RANKL, OPG, ALP and Col-A gene expression analysis revealed that RC-D potentially halts the osteoclastic activity via downregulation of RANKL mRNA expression. In short, RC-D prepared and selected via RAM developed in this study has shown promising anti-osteoporotic characteristics in SaOS-2 cells and might be considered as a functional food for bone quality management. | Quah, Yixian; Lee, Eon-Bee; Chan, Jireh Yi-Le; Jang, Seung-Hee; Park, Seung-Chun | Kyungpook Natl Univ, Coll Vet Med, Lab Vet Pharmacokinet & Pharmacodynam, 80 Daehak Ro, Daegu 41566, South Korea; Univ Tunku Abdul Rahman, Fac Business & Finance, Dept Finance, Kampar, Perak, Malaysia; Univ Tunku Abdul Rahman, Ctr IoT & Big Data, Kampar, Perak, Malaysia; Teazen Co Ltd, Teazen Res Ctr, Anyang Si, South Korea | Lee, Jung Bok/HHZ-3200-2022; Yixian, Quah/ABE-7629-2021; Park, Seung-Chun/AAV-3388-2021 | 55886933200; 57216526135; 57204478042; 39561084700; 7501832396 | parksch@knu.ac.kr; | ALL LIFE | ALL LIFE | 2689-5293 | 2689-5307 | 13 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2020 | N/A | 0.16 | 2025-06-25 | 4 | 5 | Ethanolic extract; gene expression; osteoblasts; red clover; Trifolium pratense | BIOCHANIN-A; BONE LOSS; ISOFLAVONES; DIFFERENTIATION | Ethanolic extract; gene expression; osteoblasts; red clover; Trifolium pratense | English | 2020 | 2020 | 10.1080/26895293.2020.1771435 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Optimization Algorithm for Driver Monitoring System using Deep Learning Approach | The driver monitoring system (DMS), also known as driver attention monitor, plays an important role for vehicle safety systems. In DMS, the system detects the driver's activities such as the state of being a driver sleepy or failure to give sufficient attention to avoid accidents. To reduce the driver mistakes while driving, the system warns the driver with an alarm sound or vibrations. For the efficient implementation of DMS, the system should work in real time without any delay. However, the current DMS has many challenges implementation to the complexity of network implementation. To reduce the DMS complexity for real time implementation, we propose an optimization algorithm, which uses a camera images for monitoring the driver activities. From the input camera images, we extract the driver's state information from the region of interest (ROI). In addition, the proposed system also extracts the driver's head pose and gaze information and monitors the driver states during driving. The experiment results from the proposed methods show accurate driver's state information and warns the driver immediately when any mistake occur from driver side. © 2020 IEEE. | Yoo, Min Woo; Han, Dong Seog | Kyungpook National University, Department of Future Automotive and IT Convergence, Daegu, South Korea; School of Electronics Engineering, Kyungpook National University, Daegu, South Korea | 57216618843; 7403219442 | 2020 International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2020 | 0.3 | 2025-06-25 | 4 | 3D Transformation; camera calibration; Deep neural network (DNN); Key-point detection | Cameras; Complex networks; Deep learning; Image segmentation; Monitoring; Optimization; Real time control; Safety engineering; Driver monitoring system; Efficient implementation; Learning approach; Optimization algorithms; Real-time implementations; State information; The region of interest (ROI); Vehicle safety systems; Behavioral research | English | Final | 2020 | 10.1109/icaiic48513.2020.9065222 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | Optimized speed and gearshift trajectories planning for autonomous electric vehicles | This paper proposes a hierarchical control scheme to solve the control problem of hybrid systems. In particular, the control variables of hybrid systems consisting of continuous and discrete variables have been decomposed in order to formulate the hierarchical structure. The proposed approach solves the decomposed problems separately, and then the solutions obtained are integrated to address the original hybrid system control problem. Compared to other conventional methods, our approach can significantly reduce the computational burden, which is the major contribution of this study. The proposed approach has been applied to the problem with gearshift and speed controls for autonomous electric vehicles, a typical control problem for a hybrid system. The gearshift and speed profiles are controlled using the short preview traffic information in order to optimize the battery energy consumption in the model predictive control framework. In addition, the performance and feasibility of the proposed algorithm has been verified by means of a simulation test over various driving conditions. © 2020 KSAE /179-02 | Han, Kyoungseok | School of Mechanical Engineering, Kyungpook National University, Daegu, 41566, South Korea | 56465294700 | kyoungsh@knu.ac.kr; | Transactions of the Korean Society of Automotive Engineers | 1225-6382 | 28 | 10 | 0.38 | 2025-06-25 | 5 | Autonomous vehicle; Dynamic programming; Electric vehicle; Hybrid system; Model predictive control | Korean | Final | 2020 | 10.7467/ksae.2020.28.10.669 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Optimizing Hybrid Energy Harvesting Mechanisms for UAVs | Drones or unmanned aerial vehicles (UAVs) are often limited in range and duration since they can carry limited fuel or small size batteries. While other technologies focusing on batteries, control algorithms, and devices, the immediate improvements could be energy harvesting in which the ambient resources would provide sufficient power for UAVs. This proposed study aims to overcome the limitations in terms of energy and to optimize the energy harvested to prolong the flight time. The proposed mechanism focuses on two resources as radio frequency (RF) and solar energy and optimizes the energy harvesting systems. Two standalone systems are used to extract electricity from surrounding environment sources. RF harvesting energy is supported by a multi-stage of the voltage multiplier. The solar energy is absorbed by solar panels with mounting more the boost converter and using the maximum power point tracking method to achieve better efficiency. The output values of the hybrid energy system will be adjusted by stabilizer and boost the current system to have proper voltage and current with the battery inputs. By adding the supported circuit and methods, the simulation results are suitable to charge electricity for the battery having the capacity 7660 mAh and show promise © 2020. Toan V.

| ○ | Article | Optimum Design and Vibration Analysis of a Naval Piercing Bomb for Impact Assessment on a Fuze Structure | To better understand the stresses, deformations, and high vibratory accelerations that occur within piercing bomb structures upon collision with steel ship structures, detailed finite element structural analyses were performed using realistic extreme design impact loads. The piercing bomb under consideration consisted of seven different materials, i. e., AISI4340, AISI4340F, gypsum, Al7075-T6, AISI1030, pelt, and MC-nylon. In particular, the influences of large strain and the impact acceleration along the bomb length on the fuse-protecting structure were investigated to reduce the likelihood of fuse malfunction as a result of transferred impact loads and/or acceleration. By optimizing the shape for compatibility with large impact loads, an improved structural piercing shell design was developed; the design has the same volume, but enhanced strain energy absorption. Accordingly, the strain and acceleration near the fuse-protecting structure were investigated by performing finite element analyses; they were determined to be negligibly small upon piercing impact. | Rhim, Soeun; Kim, Cheol; Kim, Ju-Yeong; Yoon, Jong-won | Kyungpook Natl Univ, Dept Mech Engn, Daegu, South Korea; Poongsan, Def R&D Inst, Daejeon, South Korea | kimchul@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 44 | 1 | ESCI | ENGINEERING, MECHANICAL | 2020 | N/A | 0 | Optimum Design; Piercing Shell; Impact; FE Analysis; Acceleration | Korean | 2020 | 2020-01 | 10.3795/ksme-a.2020.44.1.021 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Optoelectric Property and Flexibility of Tin-Doped Indium Oxide (ITO) Thin Film | Transparent conducting electrodes (TCEs) are key materials for electronic devices such as flat panel displays (e.g., a liquid crystal display and a light emitting diode display), photovoltaic cells, and transparent transistors. Tin-doped indium oxide (ITO) is known to be highly conductive/transparent, but rigid. In this study, very thin (<35 nm) ITO films with amorphous phases were prepared on flexible substrates and their optoelectric properties investigated. A 10 nm-thick ITO film was also fabricated. Because of their low thickness, their transmittances were above 80% at similar to 550 nm wavelength. Their sheet resistances were below 0.7 k Omega/sq and decreased with increasing film thickness. An interesting observation was that their sheet resistances were nearly unchanged even at a bending radius of similar to 2 mm. These optoelectric properties and flexibility demonstrate that the ITO films fabricated in this study are suitable transparent conducting oxides for the electrodes of flexible optoelectric devices. | Park, Ji Young; Park, Hee Jung | Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, 2559 Gyeongsang Daero, Sangju 37224, South Korea; Dankook Univ, Dept Mat Sci & Engn, 119 Dandae Ro, Cheonan 31116, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 6 | 8 | ITO; Transparent Conducting Oxide; Sheet Resistance; Transmittance; Flexibility | TRANSPARENT; DEPENDENCE | English | 2020 | 2020-06 | 10.1166/jnn.2020.17489 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Optoelectronic Properties of Sol-gel Processed SnO2 Thin Film Transistors | In this study, a highly crystalline SnO2 thin film was formed using a sol–gel process. In addition, a SnO2 thin-film transistor was successfully fabricated. The fabricated SnO2 thin-film transistor exhibited conventional n-type semiconductor properties, with a mobility of 0.1 cm2 V-1 s-1, an on/off current ratio of 1.2 × 105, and a subthreshold swing of 2.69. The formed SnO2 had a larger bandgap (3.95 eV) owing to the bandgap broadening effect. The fabricated photosensor exhibited a responsivity of 1.4 × 10-6 Jones, gain of 1.43 × 107, detectivity of 2.75 × 10-6 cm Hz1/2 W−1, and photosensitivity of 4.67 × 102. © 2020, Korean Sensors Society.

| ○ | Article | Organic Thin Film Transistors Fabricated by a Solution Process Using Direct Patterned Single-Layer Graphene Electrodes | We propose the direct transfer method of single-layer graphene (SLG) from metal catalyst Cu-foil to a polymeric insulator and the direct patterning method of the SLG for electrodes of organic thin-film transistors (OTFTs) without contamination using soft-lithography. Through soft-lithography, SLG can be formed in various patterns relatively easily in comparison with the conventional photolithography method that has multiple complex process steps to make graphene patterns. Furthermore, the 6,13-bis(triisopropylsilylethynyl) pentacene OTFTs are fabricated in solution with SLG source and drain electrodes. As a result, the field-effect mobility of OTFTs based on SLG electrodes was enhanced about 4 times in comparison with that of OTFTs using typical metal electrodes due to the decrease in contact resistance. | Kim, Do-Kyung; Han, Jae-Hyung; Choi, Muhan; Bae, Jin-Hyuk | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehakro, Daegu 41566, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 10 | 0 | Direct Patterning; Soft-Lithography; Single-Layer Graphene; Organic Thin-Film Transistors; Solution-Process | DRY TRANSFER; ALIGNMENT | English | 2020 | 2020-10 | 10.1166/jnn.2020.18594 | 바로가기 | 바로가기 | ||||||||||||||||||

However, our understanding of the molecular mechanisms controlling internode elongation is still limited in crop plant species. Here, we report the functional identification of an atypical basic helix-loop-helix transcription factor (OsbHLH073) through gain-of-function studies using overexpression (OsbHLH073-OX) and activation tagging (osbhlh073-D) lines of rice. The expression of OsbHLH073 was significantly increased in the osbhlh073-D line. The phenotype of osbhlh073-D showed semi-dwarfism due to deficient elongation of the first internode and poor panicle exsertion. Transgenic lines overexpressing OsbHLH073 confirmed the phenotype of the osbhlh073-D line. Exogenous gibberellic acid (GA3) treatment recovered the semi-dwarf phenotype of osbhlh073-D plants at the seedling stage. In addition, quantitative expression analysis of genes involving in GA biosynthetic and signaling pathway revealed that the transcripts of rice ent-kaurene oxidases 1 and 2 (OsKO1 and OsKO2) encoding the GA biosynthetic enzyme were significantly downregulated in osbhlh073-D and OsbHLH073-OX lines. Yeast two-hybrid and localization assays showed that the OsbHLH073 protein is a nuclear localized-transcriptional activator. We report that OsbHLH073 participates in regulating plant height, internode elongation, and panicle exsertion by regulating GA biosynthesis associated with the OsKO1 and OsKO2 genes. | Lee, Jinwon; Moon, Sunok; Jang, Seonghoe; Lee, Sichul; An, Gynheung; Jung, Ki-Hong; Park, Soon Ki | Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Kyung Hee Univ, Grad Sch Biotechnol, Yongin 17104, South Korea; Kyung Hee Univ, Crop Biotech Inst, Yongin 17104, South Korea; World Vegetable Ctr Korea Off WKO, Wanju Gun 55365, Jellabuk Do, South Korea; Inst Basic Sci IBS, Ctr Plant Aging Res, Daegu 42988, South Korea | ; Jung, Ki/L-5570-2019 | 57210899223; 7401616474; 7402219048; 8073339800; 7102580545; 56022522000; 8055974900 | leejinwon@outlook.com;moonsun@khu.ac.kr;seonghoe.jang@worldveg.org;scironlee@gmail.com;genean@khu.ac.kr;khjung2010@khu.ac.kr;psk@knu.ac.kr; | PLANTS-BASEL | 2223-7747 | 9 | 4 | 1.43 | 2025-06-25 | 23 | 21 | bHLH transcription factor; gibberellin; GA homeostasis; internode elongation; OsbHLH073; plant height; rice | DNA INSERTIONAL MUTAGENESIS; GENOME-WIDE ANALYSIS; CATALYZES 3 STEPS; TRANSCRIPTION FACTOR; GIBBERELLIN BIOSYNTHESIS; SEED-GERMINATION; GREEN-REVOLUTION; CELL ELONGATION; CYTOCHROME-P450 MONOOXYGENASE; FLOWERING-TIME | BHLH transcription factor; GA homeostasis; Gibberellin; Internode elongation; OsbHLH073; Plant height; Rice | English | 2020 | 2020-04 | 10.3390/plants9040547 | 바로가기 | 바로가기 | 바로가기 |
