| ○ | Article | Lateral Motion Control of Electronic-Four-Wheel Drive Vehicles for Enhancement of Cornering Performance | A lateral motion control to enhance the cornering performance of electronic-four-wheel drive(e-4WD) vehicles is introduced in this paper. The proposed controller aims to optimally provide the in-wheel motor(IWM) torques to each wheel assisting the vehicle in following the desired trajectories. It includes a yaw rate reference for neutral-steering, which leads to enhanced cornering performance. A smooth sliding mode controller(SMC) is utilized based on a bicycle model to generate the desired yaw moment. Lastly, a torque distribution method with the Daisy-chaining allocation is utilized within an available torque operation area of IWM. Using the CarSim software, the proposed control algorithm is simulated. The effectiveness of the proposed approach is evaluated using various driving scenarios. It is confirmed that some evaluation factors in cornering performance are improved. © 2020 Korean Society of Automotive Engineers.

| ○ | ○ | Article | LD50 determination and phenotypic evaluation of three Echeveria varieties induced by chemical mutagens | Objective The study aims to determine the Lethal Dose 50 (LD50) of Echeveria varieties as induced by chemical mutagens. Methods Three cultivated varieties from Echeveria species, namely 'Brave,' 'Viyant,' and 'Snow bunny,' were induced with chemical mutagens: colchicine, ethyl methanesulfonate (EMS), methyl methanesulfonate (MMS), and sodium azide (NaN3). Each mutagen was diluted to different concentrations: colchicine (0.2%, 0.4%, 0.6%, 0.8%, 1.0%), NaN3 (0.02%, 0.04%, 0.06%, 0.08%, 0.1%), EMS, and MMS (0.1%, 0.2%, 0.3%, 0.4%, 0.5%). Soaking durations for each concentration level were 3, 6, 9, and 12 h. The survival rate and phenotypic data for mutated plants per variety in response to chemical mutagens were collected. Results The LD50 evaluation revealed maximum concentration and treatment duration vary per varieties. Regardless of varieties, EMS-treated leaf cuttings had the highest survival rate. However, upon phenotypic evaluation, the results revealed that mutagenic plants were only taken from those treated with colchicine. Conclusion The use of colchicine to produce mutated succulents should be further investigated at the molecular level. The results of the study are highly beneficial for mutation breeding programs for other succulent varieties or other related crops. | Cabahug, Raisa Aone M.; Ha, My Khanh Tran Thi; Lim, Ki-Byung; Hwang, Yoon-Jung | Sahmyook Univ, Chromosome Res Inst, Seoul 01795, South Korea; Sahmyook Univ, Dept Convergence Sci, Seoul 01795, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; Sahmyook Univ, Dept Environm Hort, Seoul 01795, South Korea | park, jun yeon/GPX-5293-2022 | 57211922965; 57216145610; 7403175915; 50061210800 | raisaaone@gmai.com;hyj@syu.ac.kr; | TOXICOLOGY AND ENVIRONMENTAL HEALTH SCIENCES | 2005-9752 | 2233-7784 | 12 | 1 | 0.44 | 2025-06-25 | 6 | 8 | Chemical mutation; Concentration; Soaking duration; Leaf cuttings; Succulents | SODIUM-AZIDE; CHROMOSOMES; FLOWER; SPP. | Chemical mutation; Concentration; Leaf cuttings; Soaking duration; Succulents | chemical mutagen; colchicine; mesylic acid ethyl ester; mesylic acid methyl ester; snow; sodium azide; Article; chemical analysis; controlled study; experimental design; factorial design; LD50; leaf lamina; maximum concentration; nonhuman; phenotype; plant breeding; priority journal; succulent; survival rate; treatment duration; varietas | English | 2020 | 2020-03 | 10.1007/s13530-020-00049-3 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | Article | Legislative and policy issues related to the advancement of the maintenance system of water resource facilities | In this study, legislative and policy issues related to advancing the maintenance system of water resource facilities were presented by investigating and analyzing the degree of aging and management status of water resource facilities. Data from the comprehensive Facility Management System (FMS) operated by the Korea Infrastructure Safety Corporation were collected and used to analyze the aging of water resource facilities. Using safety grade data categorized by facility, type, local area, and grade, the ratio of dangerous facilities and the aging rate were calculated to analyze the status of water resource facilities and guidelines and manuals related to water resource facilities were investigated. Through this, four required actions to address legislative and policy issues were presented: 1) Readjusting the scope of water resource facilities and supplementing guidelines and manuals, 2) Establishing a maintenance system considering changes in disaster conditions, 3) Improving the FMS and activating standard linkage services, and 4) Establishing a facility asset management system. © 2020 Korea Water Resources Association. | Lee, Giha; Yeon, Minho; Lee, Daeeop; Kim, Seongwon; Kim, Jinsoo | Department of Disaster Prevention and Environmental Engineering, Kyungpook National University, Sangju, South Korea; Department of Disaster Prevention and Environmental Engineering, Kyungpook National University, Sangju, South Korea; Emergency Management Institute, Kyungpook National University, Sangju, South Korea; Emergency Management Institute, Kyungpook National University, Sangju, South Korea; National Assembly Research Service, Seoul, South Korea | 35069799400; 57223436971; 57202956223; 57217629889; 58245110500 | hydroeop@gmail.com; | Journal of Korea Water Resources Association | 2799-8746 | 53 | S-1 | 0 | 2025-06-25 | 0 | Aging; Dangerous facility; Facility management system; Safety grade; Water resource facility | Korean | Final | 2020 | 10.3741/jkwra.2020.53.s-1.773 | 바로가기 | 바로가기 | ||||||||||||||||

| ○ | Article | Lightlike hypersurfaces of an indefinite kaehler manifold with an (ℓ, m)-type connection | Jin [1] defined an (ℓ, m)-type connection on semi-Riemannian manifolds. Semi-symmetric non-metric connection and non-metric φ-symmetric connection are two important examples of this connection such that (ℓ, m) = (1, 0) and (ℓ, m) = (0, 1), respectively. In semi-Riemannian geometry, there are few literatures for the lightlike geometry, so we expose new theories for non-degenerate submanifolds in semi-Riemannian geometry. The goal of this paper is to study a characterization of a (Lie) recurrent lightlike hypersurface M of an indefinite Kaehler manifold with an (ℓ, m)-type connection when the charateristic vector field is tangnet to M. In the special case that an indefinite Kaehler manifold of constant holomorphic sectional curvature is an indefinite complex space form, we investigate a lightlike hypersurface of an indefinite complex space form with an (ℓ, m)-type connection when the charateristic vector field is tangnet to M. Moreover, we show that the total space, the complex space form, is characterized by the screen conformal lightlike hypersurface with an (ℓ, m)-type connection. With a semi-symmetric non-metric connection, we show that an indefinite complex space form is flat. © 2020 by authors, all rights reserved. | Lee, Jae Won; Jin, Dae Ho; Lee, Chul Woo | Department of Mathematics Education and RINS, Gyeongsang National University, Jinju, 52828, South Korea; Department of Mathematics, Dongguk University, Gyeongju, 38066, South Korea; Department of Mathematics, Kyungpook National University, Daegu, 41566, South Korea | 55917980500; 36182940900; 56100882300 | Mathematics and Statistics | 2332-2071 | 8 | 3 | 0 | 2025-06-25 | 0 | Compound Non-symmetric Non-metric Con-nection; Indefinite Complex Space Form; Indefinite Kaehler Manifold; Lightlike Hypersurface | English | Final | 2020 | 10.13189/ms.2020.080306 | 바로가기 | 바로가기 | |||||||||||||||||

In particular, we focus on such lightlike hypersurfaces M for which the structure tensor field F is either recurrent or Lie recurrent, or such that M itself is totally umbilical or screen totally umbilical. | Lee, Chul Woo; Lee, Jae Won | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea; Gyeongsang Natl Univ, Dept Math Educ, Jinju 52828, South Korea; Gyeongsang Natl Univ, RINS, Jinju 52828, South Korea | 56100882300; 55917980500 | mathisu@knu.ac.kr;leejaew@gnu.ac.kr; | KYUNGPOOK MATHEMATICAL JOURNAL | KYUNGPOOK MATH J | 1225-6951 | 0454-8124 | 60 | 2 | ESCI | MATHEMATICS | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | (l, m)-type connection; recurrent; Lie recurrent; lightlike hypersurface; indefinite nearly trans-Sasakian manifold | (l,m)-type connection; Indefinite nearly trans-Sasakian manifold; Lie recurrent; Lightlike hypersurface; Recurrent | English | 2020 | 2020-06 | 10.5666/kmj.2020.60.2.223 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Liquid Level System Realizing Van de Vusse Reactor Dynamics and its Control Experiments | Van de Vusse reactors show the maximum points in input-output steady state maps and dramatic changes in their dynamic characteristics around those maximum points. According to their operating regions, there appear sign changes in steady state gains and nonlinear characteristics such as non-minimum phase dynamics which cause difficulties in applying controllers. Many nonlinear controllers that are available and newly designed are applied to these Van de Vusse reactor processes and their performances are tested. Reactor examples with real reactions have been reported. However, due to difficulties in constructing and operating chemical reactor systems, they are not adequate to be used for real applications of control experiments and hence most of results are based on simulations studies. Here, we propose a liquid level system that realizes most of the steady state and dynamic characteristics of Van de Vusse reactor, and two nonlinear control methods that can be used as base methods to compare nonlinear controllers newly designed. Liquid level experimental system and two nonlinear control methods are very simple and can be used to test performances of nonlinear controllers in practice. | Lee, Jietae | Kyungpook Natl Univ, Dept Chem Engn, 80 Daehak Ro, Daegu 41566, South Korea | Lee, Si/ABH-1408-2020 | 7601455194 | jtlee@knu.ac.kr; | KOREAN CHEMICAL ENGINEERING RESEARCH | KOREAN CHEM ENG RES | 0304-128X | 2233-9558 | 58 | 2 | ESCI | ENGINEERING, CHEMICAL | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | Van de Vusse reactor; Input multiplicity; Global stability; PI control; Parallel compensator; Extremum seeking control | FEEDBACK | Extremum seeking control; Global stability; Input multiplicity; Parallel compensator; PI control; Van de Vusse reactor | Korean | 2020 | 2020-04 | 10.9713/kcer.2020.58.2.184 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Lirioresinol B dimethyl ether inhibits NF-κB and COX-2 and activates IκBα expression in CCl4-induced hepatic fibrosis | Background: Inflammation is one of the key components in the initiation and progression of hepatic diseases. If not treated, inflammation may cause cell dysplasia, and ultimately cancer. In the current study, we investigated the anti-inflammatory and anti-cancer activities of plant isolated compound Lirioresinol B Dimethyl Ether (LBDE) extracted from the seeds of Magnolia fargesii CHENG (Magnoliaceae) against HepG2 cells as well as in BALB/C male mice. Methods: We assessed the antioxidant and anti-proliferative effects of plant compounds using DPPH assay and HepG2 cell lines. Carbon tetrachloride (CCl4) and Diethylnitrosamine (DEN) were used to induce liver cell dysplasia followed by hepatocellular carcinoma (HCC) in BALB/C male mice for 12 weeks. We investigated the underlying mechanism by using histopathology and immunoblot experiments. Results: Intraperitoneal injection of LBDE (50 mg/kg body weight/day) inhibited CCl4-induced HCC. Free radical scavenging assay shows the strong anti-oxidant activity of LBDE. Western blot results show that LBDE downregulated nuclear factor kappa B (NF kappa B) and cyclooxygenase (COX-2) by preventing the phosphorylation of I kappa B alpha (I kappa B alpha) in CCl4 treated group. LBDE also improved liver function by decreasing Alkaline Phosphatase (ALP), aspartate aminotransferase (AST) and Alanine Aminotransferase (ALT) levels. Histopathology results revealed that LBDE decreased granulomas and express normal morphology of hepatocytes. Conclusions: These preliminary results show that LBDE has the potential to inhibit CCl4-induced liver cell dysplasia and prevents cancer development by regulating NF kappa B/COX-2 activation. | Shehzad, Adeeb; Rehmat, Shagufta; Ul-Islam, Salman; Ahmad, Rizwan; Aljafary, Meneerah; Alrushaid, Noor A.; Al-Suhaimi, Ebtesam A. | Imam Abdulrahman Bin Faisal Univ, Inst Res & Med Consultat, Dept Clin Pharm, Dammam, Saudi Arabia; Natl Univ Sci & Technol, Sch Mech & Mfg Engn SMME, Dept Biomed Engn & Sci, Islamabad, Pakistan; Kyungpook Natl Univ, Sch Life Sci, Daegu, South Korea; Imam Abdulrahman Bin Faisal Univ, Coll Clin Pharm, Nat Prod & Alternat Med, Dammam, Saudi Arabia; Imam Abdulrahman Bin Faisal Univ, Coll Sci, Dept Biol, Dammam, Saudi Arabia; Imam Abdulrahman Bin Faisal Univ, Inst Res & Med Consultat, Dammam, Saudi Arabia | Aljafary, Meneerah/AAH-8129-2021; Al-Suhaimi, Ebtesam/C-6054-2015; rehmat, shagufta/ABG-4392-2020; Shehzad, Adeeb/HHN-4847-2022; Ahmad, Rizwan/X-1978-2019 | 36162526700; 57218561112; 56985186700; 8724199500; 57204466004; 57218561456; 37070362000 | ealsuhaimi@iau.edu.sa; | BMC COMPLEMENTARY MEDICINE AND THERAPIES | BMC COMPLEMENT MED | 2662-7671 | 20 | 1 | SCIE | INTEGRATIVE & COMPLEMENTARY MEDICINE | 2020 | N/A | 0.7 | 2025-06-25 | 8 | 10 | Inflammation; Lirioresinol B dimethyl ether; Antioxidant; NF kappa B; COX-2; Hepatic fibrosis | MOLECULAR-MECHANISM; CURCUMIN; INFLAMMATION; VITRO; CARCINOMA; PATHWAYS; SURVIVAL; LIGNANS; INJURY | Antioxidant; COX-2; Hepatic fibrosis; Inflammation; Lirioresinol B dimethyl ether; NFκB | Animals; Anti-Inflammatory Agents; Antineoplastic Agents; Cyclooxygenase 2; Cyclooxygenase 2 Inhibitors; Disease Models, Animal; Furans; Hep G2 Cells; Humans; Liver Cirrhosis; Male; Mice; Mice, Inbred BALB C; Molecular Structure; NF-kappa B; NF-KappaB Inhibitor alpha; Plant Extracts; Seeds; antiinflammatory agent; antineoplastic agent; cyclooxygenase 2; cyclooxygenase 2 inhibitor; furan derivative; I kappa B kinase alpha; immunoglobulin enhancer binding protein; lirioresinol B dimethyl ether; plant extract; Ptgs2 protein, mouse; animal; Bagg albino mouse; chemical structure; disease model; Hep-G2 cell line; human; liver cirrhosis; male; metabolism; mouse; plant seed | English | 2020 | 2020-02-11 | 10.1186/s12906-020-2839-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Review | Literature review and meta-analysis of problem-based learning in nursing students | Purpose: The objective of this systematic review and meta-analysis was to estimate the effectiveness of problem-based learning in developing student nurses’ critical thinking, problem solving, and self-directed learning. Methods: To conduct the meta-analysis, 1,963 studies were retrieved from eight databases (Pubmed, EMbase, CINAHL, Cochrane Library, KERIS, KISS, NDSL, KoreaMed) without restriction on publication year. Articles published up to March 2019 were selected for this study. Fourteen studies were selected for meta-analysis based on satisfaction of inclusion criteria and low risk of bias. Baseline demographic data, exercise features, and outcome data were extracted from all trials included. The data was analyzed using the RevMan 5.3 program. Results: Most studies were of low risk of bias. The pooled effect size showed problem-based learning was able to improve nursing students’ critical thinking (ES=0.29, 95% Cl=0.04~0.54, p=.002), problem solving (ES=0.39, 95% Cl=-0.09~0.87, p=.11), and self-directed learning (ES=0.35, 95% Cl=-0.22~0.91, p=.23) compared with traditional lectures. Conclusion: PBL help improve the critical thinking in nursing students. Although problem solving and self directed learning were not affected, more research with a larger sample size and repeated meta-analysis of PBL are required. © 2020 Korean Academy of Fundamentals of Nursing. | Song, Yeoungsuk; Park, Seurk | College of Nursing, Kyungpook National University, Daegu, South Korea; College of Nursing, Kyungpook National University, Daegu, South Korea | 55494171100; 57204569309 | tommy2309@naver.com; | Journal of the Korean Academy of Fundamentals of Nursing | 1225-9012 | 27 | 3 | 0.18 | 2025-06-25 | 4 | Meta-analysis; Problem solving; Problem-based learning; Self-directed learning; Thinking | Korean | Final | 2020 | 10.7739/jkafn.2020.27.3.246 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Lithium-doped two-dimensional perovskite scintillator for wide-range radiation detection | Two-dimensional lead halide perovskites have demonstrated their potential as high-performance scintillators for X- and gamma-ray detection, while also being low-cost. Here we adopt lithium chemical doping in two-dimensional phenethylammonium lead bromide (PEA)(2)PbBr4 perovskite crystals to improve the properties and add functionalities with other radiation detections. Li doping is confirmed by X-ray photoemission spectroscopy and the scintillation mechanisms are explored via temperature dependent X-ray and thermoluminescence measurements. Our 1:1 Li-doped (PEA)(2)PbBr4 demonstrates a fast decay time of 11ns (80%), a clear photopeak with an energy resolution of 12.4%, and a scintillation yield of 11,000 photons per MeV under 662keV gamma-ray radiation. Additionally, our Li-doped crystal shows a clear alpha particle/gamma-ray discrimination and promising thermal neutron detection through Li-6 enrichment. X-ray imaging pictures with (PEA)(2)PbBr4 are also presented. All results demonstrate the potential of Li-doped (PEA)(2)PbBr4 as a versatile scintillator covering a wide radiation energy range for various applications. | Xie, Aozhen; Hettiarachchi, Chathuranga; Maddalena, Francesco; Witkowski, Marcin E.; Makowski, Michal; Drozdowski, Winicjusz; Arramel, Arramel; Wee, Andrew T.

| ○ | ○ | Article | Long-term benefits of chest compression-only cardiopulmonary resuscitation training using real-time visual feedback manikins: a randomized simulation study | Objective Cardiopulmonary resuscitation (CPR) education with a feedback device is known to result in better CPR skills compared to one without the feedback device. However, its long-term benefits have not been established. The purpose of this study was to evaluate the long-term CPR skill retention after training using real-time visual manikins in comparison to that of non-feedback manikins. Methods We recruited 120 general university students who were randomly divided into the real-time feedback group (RTFG) and the non-feedback group. Of them, 95 (RTFG, 48; non-feedback group, 47) attended basic life support and automated external defibrillation training for 1 hour. For comparison of retention of CPR skills, the two groups were evaluated based on 2-minute chest compression performed immediately after training and at 3, 6, and 9 months. The CPR parameters between the two groups were also compared using a generalized linear model. Results At immediately after training, the performance of RTFG was better in terms of average chest compression depth (51.9 +/- 1.1 vs. 45.5 +/- 1.1, p< 0.001) and a higher percentage of adequate chest compression depth (51.0 +/- 4.1 vs. 26.9 +/- 4.2, p< 0.001). This significant difference was maintained until 6 months after training, but there was no difference at 9 months after training. However, there was no significant difference in the chest compression rate and the correct hand position at any time point. Conclusion CPR training with a real-time visual feedback manikin improved skill acquisition in chest compression depth, but only until 6 months after the training. It could be a more effective educational method for basic life support training in laypersons. | Jang, Tae Chang; Ryoo, Hyun Wook; Moon, Sungbae; Ahn, Jae Yun; Lee, Dong Eun; Lee, Won Kee; Kwak, Sang Gyu; Kim, Jung Ho | Daegu Catholic Univ, Dept Emergency Med, Sch Med, Daegu, South Korea; Kyungpook Natl Univ, Dept Emergency Med, Sch Med, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Dept Med Informat, Sch Med, Daegu, South Korea; Daegu Catholic Univ, Dept Med Stat, Sch Med, Daegu, South Korea; Yeungnam Univ, Dept Emergency Med, Coll Med, Daegu, South Korea | Ahn, Jae Yun/N-2652-2017; Lee, Dong Eun/HTN-4501-2023; Kwak, Sang Gyu/AAG-4341-2021; Kim, Jungho/LDE-9088-2024; Kim, Jung Ho/LDE-9088-2024 | 57189297849; 55350557500; 57191584601; 56937505400; 57202299238; 22953484700; 56645812600; 57205704177 | ryoo@knu.ac.kr; | CLINICAL AND EXPERIMENTAL EMERGENCY MEDICINE | CLIN EXP EMERG MED | 2383-4625 | 7 | 3 | ESCI | EMERGENCY MEDICINE | 2020 | N/A | 0.46 | 2025-06-25 | 10 | 9 | Heart arrest; Cardiopulmonary resuscitation; Education; Manikins; Simulation training | BASIC LIFE-SUPPORT; CPR PERFORMANCE; RETENTION; IMPROVES; QUALITY; SYSTEM; INSTRUCTOR; DEVICE | Cardiopulmonary resuscitation; Education; Heart arrest; Manikins; Simulation training | adult; Article; basic life support; body mass; body weight; controlled study; education; female; follow up; hand; human; knowledge; major clinical study; male; questionnaire; randomized controlled trial; resuscitation; student retention; training; visual feedback; young adult | English | 2020 | 2020-09 | 10.15441/ceem.20.022 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Long-Term Result of Tibioperoneal Trunk Bypass with an Autogenous Graft Using the Varicose Great Saphenous Vein for Acute Limb Ischemia | For the management of acute limb ischemia (ALI) and multilevel arterial occlusive disease, tibial bypass using the saphenous vein has been considered a mainstay due to the long-term durability in selected patients with acceptable saphenous veins and comorbid conditions. Traditionally, bypass using a varicose autogenous graft has been contraindicated due to the risk of late aneurysmal dilation and rupture. Here, we describe a patient who presented with ALI and received tibioperoneal trunk bypass using a varicose autogenous graft. The patient has been doing well during the 72-month follow-up without recurrent symptoms or revision. The follow-up images showed a favorably patent graft with mild aneurysmal changes at the valve cusp adjacent to the knee. If there are no other appropriate autologous veins for revascularization, a varicose autogenous vein graft may be a useful option for limb salvaging in selected patients with multilevel arterial occlusive diseases. | Kim, Hyung-Kee; Hwang, Deokbi; Huh, Seung | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Surg, Div Vasc Surg,Sch Med, Daegu, South Korea | ; Kim, Hyung-Kee/JBR-8125-2023 | 35169819900; 57194422879; 7101832929 | hkkim6260@knu.ac.kr; | VASCULAR SPECIALIST INTERNATIONAL | 2288-7970 | 2288-7989 | 36 | 3 | 0 | 2025-06-25 | 2 | 0 | Peripheral arterial disease; Operative therapy; Varicose veins; Ischemia | Ischemia; Operative therapy; Peripheral arterial disease; Varicose veins | acetylsalicylic acid; clopidogrel; politef; acute limb ischemia; adult; anamnesis; ankle brachial index; Article; bypass surgery; case report; clinical article; computed tomographic angiography; computer assisted tomography; dual antiplatelet therapy; duplex Doppler ultrasonography; femoropopliteal bypass; follow up; graft occlusion; human; image analysis; knee; leg pain; leg varicosis; limb ischemia; limb salvage; long term care; male; middle aged; monotherapy; patch angioplasty; physical examination; popliteal artery; preoperative evaluation; prosthesis thrombosis; revascularization; saphenous vein; saphenous vein graft; symptom; thrombectomy; tibioperoneal trunk bypass; varicosis; vein bypass | English | 2020 | 2020-09 | 10.5758/vsi.200033 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Proceedings Paper | Low-cost Hardware Architecture for Integral Image Generation using Word Length Reduction | An integral image is widely used in face detection to calculate feature values at high speed. However, implementing integral images in hardware requires considerable logic and memory resources. This paper proposes a hardware architecture for integral image generation with reduced resource usage by applying the word length reduction method. When implemented in an FPGA, the proposed architecture uses about 83% fewer Slice LUTs than the conventional integral image method. Therefore, the proposed architecture is suitable for low-cost real-time face detection systems. | Kim, Junghwan; Hyun, Jongkil; Moon, Byungin | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Moon, Byungin/ACE-5308-2022 | 57222321332; 56911778100; 55419717700 | jh5746@knu.ac.kr;26712isjk@knu.ac.kr;bihmoon@knu.ac.kr; | 2020 17TH INTERNATIONAL SOC DESIGN CONFERENCE (ISOCC 2020) | 2163-9612 | 0 | 2025-06-25 | 1 | 1 | FPGA; hardware architecture; integral image; face detection | face detection; FPGA; hardware architecture; integral image | Costs; Programmable logic controllers; Hardware architecture; Integral images; Low cost hardware; Memory resources; Proposed architectures; Real-time face detection; Resource usage; Word-length reduction; Face recognition | English | 2020 | 2020 | 10.1109/isocc50952.2020.9332974 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Conference paper | LSTM Enabled Artificial Intelligent Smart Gardening System | In the present era, internet of things (IoT) is prevailing very much in our daily life serving the concept of the smart applications, in which one can operate remote objects from a distant place. However, connectivity of the billions of devices has become a major concern in most of the prevailing researches. Massive connected devices used for smart applications consumes the network resources such as bandwidth and consumes the power to operate. Due to limited bandwidth, intermittent connectivity issues arises between smart devices which incorporates delay in the network. LoRaWAN (Long range Low power wide area network) developed by SemtechTM is a MAC layer protocol developed primarily for the IoT devices. In this paper, we implemented Long Short Term (LSTM) based smart gardening system, where end nodes collect the data from surrounding and sends to gateway using LoRa protocol. Edge Server is installed with the gateway on which LSTM based machine learning algorithm is running which predicts the future sensor values. For the predicted interval of time gateway sends the message to end nodes to remain inactive which saves the network bandwidth and also increases the life of sensors. © 2020 ACM. | Saad, Malik Muhammad; Khan, Muhammad Toaha Raza; Tariq, Muhammad Ashar; Kim, Dongkyun | School of Computer Science and Engineering, Kyungpook National University, South Korea; School of Computer Science and Engineering, Kyungpook National University, South Korea; Department of Artificial Intelligence, Kyungpook National University, South Korea; School of Computer Science and Engineering, Kyungpook National University, South Korea | 57220715290; 57202044597; 57219865336; 35753648800 | ACM International Conference Proceeding Series | 0.38 | 2025-06-25 | 6 | IoT; LSTM; Neural Networks; Sensors; Smart Farm | Bandwidth; Internet of things; Learning algorithms; Long short-term memory; Low power electronics; Machine learning; Wide area networks; Artificial intelligent; Intermittent connectivity; Internet of Things (IOT); Limited bandwidth; MAC layer protocols; Network bandwidth; Network resource; Smart applications; Gateways (computer networks) | English | Final | 2020 | 10.1145/3400286.3418260 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | Lysimetric analysis for transpiration and carbon accumulation of cnidium officinale makino in hot weather conditions | Background: Evaluation of transpiration is required for agricultural and environmental management applications, as crop yields and plant growth are primarily water limited. This study aimed to determine the transpiration and carbon accumulation of Cnidium officinale. Methods and Results: The transpiration of C. officinale was evaluated using weighing lysimeter. The relationship between transpiration and factors such as solar radiation, air temperature, and leaf area was assessed. Transpiration increased as the leaf area increased with the growth stage. Further-more, daily transpiration per unit leaf area was 0.69 ± 0.16 g·㎝−2·day−1 and there were no signifi-cant differences in daily transpiration during the cultivation period. The maximum transpiration was 620.6 g m−2·h−1 and diurnal changes in transpiration were highly correlated with solar radiation although the maximum transpiration was observed at the air temperatures of 20℃-26℃. The ratio of carbon accumulation to transpiration was 0.12%. Conclusions: Our results indicated that the transpiration of C. officinale is primarily regulated by solar radiation energy on clear days and that 97% of the water is discharged through transpiration for heat dissipation. Therefore, weighing lysimeters can measure transpiration accurately and may be useful in interpreting plant growth. © 2020, Korean Society of Medicinal Crop Science.
