| ○ | ○ | Article | ST-Trie: A Novel Indexing Scheme for Efficiently Querying Heterogeneous, Spatiotemporal IoT Data | Recently, various environmental data, such as microdust pollution, temperature, humidity, etc., have been continuously collected by widely deployed Internet of Things (IoT) sensors. Although these data can provide great insight into developing sustainable application services, it is challenging to rapidly retrieve such data, due to their multidimensional properties and huge growth in volume over time. Existing indexing methods for efficiently locating those data expose several problems, such as high administrative cost, spatial overhead, and slow retrieval performance. To mitigate these problems, we propose a novel indexing scheme termed ST-Trie, for efficient retrieval over spatiotemporal IoT environment data. Given IoT sensor data with latitude, longitude, and time, the proposed scheme first converts the three-dimensional attributes to one-dimensional index keys. The scheme then builds a trie-based index, consisting of internal nodes inserted by the converted keys and leaf nodes containing the keys and pointers to actual IoT data. We leverage this index to process various types of queries. In our experiments with three real-world datasets, we show that the proposed ST-Trie index outperforms existing approaches by a substantial margin regarding response time. Furthermore, we show that the query processing performance via ST-Trie also scales very well with an increasing time interval. Finally, we demonstrate that when compressed, the ST-Trie index can significantly reduce its space overhead by approximately a factor of seven. | Chu, Hawon; Kim, Jaeseong; Kim, Seounghyeon; Suh, Young-Kyoon; Lee, Ryong; Jang, Rae-Young; Park, Minwoo | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Korea Inst Sci & Technol Informat, Res Data Sharing Ctr, Daejeon 34141, South Korea | 57217226909; 57219978275; 58743827200; 55443739900; 34880307100; 57216709474; 57203052386 | hwchu@knu.ac.kr;jskim94@knu.ac.kr;kshy9598@knu.ac.kr;yksuh@knu.ac.kr;ryonglee@kisti.re.kr;raezero@kisti.re.kr;pminwoo@kisti.re.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 22 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 0 | 2025-06-25 | 1 | 1 | Internet of Things sensors; environment data; spatiotemporal indexing; trie; query processing | Environment data; Internet of Things sensors; Query processing; Spatiotemporal indexing; Trie | computer system; cost analysis; experimental study; index method; information processing; Internet; sensor; software; spatiotemporal analysis | English | 2020 | 2020-11 | 10.3390/su12229727 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Stronger Impact of Interpersonal Aspects of Satisfaction Versus Tangible Aspects on Sustainable Level of Resident Loyalty in Continuing Care Retirement Community: A Case Study | The objectives of the study were to examine the impact of interpersonal and tangible aspects of resident satisfaction on word-of-mouth (WOM) intention in community-embedded third places with long-duration service experiences and to investigate the mediating effect of interpersonal aspects on the relationship between tangible resident satisfaction and WOM intention. Paper-based survey questionnaires and postage-paid envelopes were mailed to 293 continuing care retirement community (CCRC) residents. Reliability and validity of the multidimensional construct of resident satisfaction were ensured through confirmatory factor analysis. Hierarchical regression analysis and MANOVA were used to test the hypotheses. A total of 157 completed surveys were received. Analysis showed that two categories of resident satisfaction were statistically distinct. Interpersonal aspects of resident satisfaction (resident involvement, social interaction, and staff care) positively impacted WOM intention more than the tangible aspects (room, home, and meals service). The relationship between tangible resident satisfaction and WOM intention was mediated by interpersonal aspects of resident satisfaction. This study contributes to the literature by (1) examining the mediating effect of interpersonal resident satisfaction between tangible satisfaction and WOM intention in community embedded third places and by (2) exploring the role of non-traditional third places, (i.e., third places nested within residential community settings) as opposed to conventional types (i.e., individual commercial settings). Thus, it addresses the call for research on permanent residents with long-duration service experiences and the effect of one location nested within another. | Lee, Ji-Eun | Kyungpook Natl Univ, Dept Food & Foodserv Ind, Sangju 37224, South Korea | 57221622859 | jelee347@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 21 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 0.14 | 2025-06-25 | 3 | 5 | embedded third places; resident satisfaction; long-duration service experiences; word-of-mouth (WOM); continuing care retirement community (CCRC) | 3RD PLACES; TRANSITIONS; ANTECEDENTS; BEHAVIOR; OLD | Continuing care retirement community (CCRC); Embedded third places; Long-duration service experiences; Resident satisfaction; Word-of-mouth (WOM) | community care; hierarchical system; questionnaire survey; regression analysis; residential location; retirement; variance analysis | English | 2020 | 2020-11 | 10.3390/su12218756 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sustainability and the Expected Effects of Office-to-Residential Conversion in Historic Downtown Areas of South Korea | South Korea has industrialized and urbanized rapidly since the 1970s, and subsequently, the historic downtown areas of major cities have been hollowed out as the population and industry have become concentrated in urban centers. Based on the Urban Decline Indicators of Korea, in accordance with the Urban Revitalization Act of the South Korean government, a comparative analysis of the population changes, office vacancy rate, building aging rate, decrease in the number of industries and employees, and housing supply and demand in historic downtown areas and new urban areas of six major South Korean cities demonstrated that all six historic downtown areas have declined significantly. Currently, little research is available in South Korea on the expansion of urban living and the inflow of urban residents through office-to-residential building conversion. Therefore, this study explores the expansion of urban residences to revitalize these historic downtown areas. To this end, this study examines the feasibility of converting poorly functioning, vacant offices in historic downtown areas into residential spaces to present a sustainable strategy for their complexation. This study finds that office-to-residential building conversion is a sustainable way to recover urban space and grow the population and industry in historic downtown areas. | Kim, Eunkwang; Lee, Sanghong | Kyungpook Natl Univ, Sch Architecture, 315,2nd Engn Bldg,80 Daehak Ro, Daegu 41566, South Korea; Inst Kyungpook Natl Univ Architecture & Urban Spa, 1506 Global Plaza,80 Daehak Ro, Daegu 41566, South Korea | 57219948902; 56165960900 | eunkwang.kim@gmail.com;Lsh@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 22 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 0.28 | 2025-06-25 | 2 | 5 | historic downtown decline; urban revitalization; urban housing; office vacancy rate; office-to-residential conversion | URBAN REGENERATION; ADAPTIVE REUSE; BUILDINGS | Historic downtown decline; Office vacancy rate; Office-to-residential conversion; Urban housing; Urban revitalization | South Korea; demand analysis; housing market; industrialization; inflow; research work; strategic approach; sustainability; urban area; urban population; urbanization | English | 2020 | 2020-11 | 10.3390/su12229576 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Sustainable Application of Hybrid Point Cloud and BIM Method for Tracking Construction Progress | Compared to the past, the complexity of construction-project progress has increased as the size of structures has become larger and taller. This has resulted in many unexpected problems with an increasing frequency of occurrence, such as various uncertainties and risk factors. Recently, research was conducted to solve the problem via integration with data-collection automation tools of construction-project-progress measurement. Most of the methods used spatial sensing technology. Thus, this study performed a review of the representative technologies applied to construction-project-progress data collection and identified the unique characteristics of each technology. The basic principle of the progress proposed in this study is its execution through the point cloud and the attributes of BIM, which were studied in five stages: (1) Acquisition of construction completion data using a point cloud, (2) production of a completed 3D model, (3) interworking of an as-planned BIM model and as-built model, (4) construction progress tracking via overlap of two 3D models, and (5) verification by comparison with actual data. This has confirmed that the technical limitations of the construction progress tracking through the point cloud do not exist, and that a fairly high degree of progress data which contains efficiency and accuracy can be collected. | Kim, Seungho; Kim, Sangyong; Lee, Dong-Eun | Yeungnam Univ Coll, Dept Architecture, Daegu 42415, South Korea; Yeungnam Univ, Sch Architecture, Gyongsan 38541, Gyeongbuk, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil & Architectural Engn, Daegu 41566, South Korea | 57191481643; 55498494400; 56605563300 | kimseungho@ync.ac.kr;sangyong@yu.ac.kr;dolee@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 10 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 1.49 | 2025-06-25 | 35 | 42 | building information modeling; drone; LIDAR; point cloud; progress tracking | SCAN-TO-BIM; DATA-ACQUISITION; MANAGEMENT; RECONSTRUCTION; TECHNOLOGIES; SYSTEM; MODEL | Building information modeling; Drone; LIDAR; Point cloud; Progress tracking | accuracy assessment; automation; complexity; data acquisition; efficiency measurement; risk factor; spatial analysis; sustainability; three-dimensional modeling; uncertainty analysis | English | 2020 | 2020-05 | 10.3390/su12104106 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | System Dynamics Model for the Improvement Planning of School Building Conditions | As the number of aged infrastructures increases every year, a systematic and effective asset management strategy is required. One of the most common analysis methods for preparing an asset management strategy is life cycle cost analysis (LCCA). Most LCCA-related studies have focused on traffic and energy; however, few studies have focused on school buildings. Therefore, an approach should be developed to increase the investment efficiency for the performance improvement of school buildings. Planning and securing budgets for the performance improvement of school building is a complex task that involves various factors, such as current conditions, deterioration behavior and maintenance effect. Therefore, this study proposes a system dynamics (SD) model for the performance improvement of school buildings by using the SD method. In this study, an SD model is used to support efficient decision-making through policy effect analysis, from a macro-perspective, for the performance improvement of school buildings. | Kang, Suhyun; Kim, Sangyong; Kim, Seungho; Lee, Dongeun | Yeungnam Univ, Sch Architecture, 280 Daehak Ro, Gyongsan 38541, Gyeongbuk, South Korea; Yeungnam Univ Coll, Dept Architecture, 170 Hyeonchung Ro, Daegu 42415, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil & Architectural Engn, 80 Daehak Ro, Daegu 41566, South Korea | 55949475400; 55498494400; 57191481643; 56605563300 | yp043422@ynu.ac.kr;sangyong@yu.ac.kr;kimseungho@ync.ac.kr;dolee@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 10 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 0.21 | 2025-06-25 | 10 | 9 | school buildings; system dynamics; deterioration; rehabilitation; lifecycle cost analysis; budget allocation | ENERGY-CONSUMPTION; CO2 EMISSIONS; MANAGEMENT; SIMULATION; WATER | Budget allocation; Deterioration; Lifecycle cost analysis; Rehabilitation; School buildings; System dynamics | building; cost analysis; decision making; life cycle analysis; performance assessment | English | 2020 | 2020-05 | 10.3390/su12104235 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The impact of infection control cost reimbursement policy on central line-associated bloodstream infections | Background: In September 2016, the Korean National Health Insurance Service began reimbursing infection control (IC) costs on the condition that a certain number of doctors and full-time nurses for IC be allocated to supported hospitals. We analyzed the impact of the IC cost reimbursement policy on central line-associated bloodstream infections (CLABSIs). Methods: A before-and-after study that analyzed the CLABSI rate trends between preintervention (January 2016 to February 2017) and intervention (March to December 2017) periods using autoregression time series analysis was performed in intensive care units (ICUs) at a 750-bed, secondary care hospital in Daegu, Republic of Korea. The enhanced IC team visited ICUs daily, monitored the implementation of CLABSI prevention bundles, and educated all personnel involved in catheter insertion and maintenance from March 2017. Results: Autoregressive analysis revealed that the CLABSI rates per month in the preintervention and intervention periods were -0.256 (95% confidence interval, -0.613 to 0.101; P = .15) and -0.602 (95% confidence interval, -0.972 to -0.232; P = .008), respectively. The rates of compliance with maximal barrier precautions significantly improved from the preintervention (36.2%) to the intervention (77.9%) period (chi(2) test, P < .001). Conclusions: The IC cost reimbursement policy accelerated the decline in CLABSI rates significantly in monitored ICUs. A nationwide study to evaluate the effectiveness of the IC cost reimbursement policy for various health care-associated infections is warranted.

| ○ | ○ | Article | The Influence of Salinity on the Removal of Ni and Zn by Sorption onto Iron Oxide- and Manganese Oxide-Coated Sand | The influence of salinity on the single and binary sorption of Ni and Zn onto iron oxide- and manganese oxide-coated sand (IOCS and MOCS) was investigated at pH = 5. The single sorption experimental data were fitted to Freundlich, Langmuir, Dubinin-Radushkevich, and Sips models, and a nonlinear sorption isotherm was observed (N-F= 0.309-0.567). The higher Brunauer-Emmett-Teller (BET) surface area (A(BET)) and cation exchange capacity (CEC) of MOCS contributed to the higher maximum sorption capacities (q(mL)) of Ni and Zn than that of IOCS. The Ni sorption capacities in the single sorption were higher than that in the binary sorption, while the Zn sorption capacities in the single sorption were less than that in the binary sorption. The single and binary sorptions onto both IOCS and MOCS were affected by the salinity, as indicated by the decrease in sorption capacities. Satisfactory predictions were shown by the binary sorption model fitting including P-factor, ideal adsorbed solution theory (IAST)-Freundlich, IAST-Langmuir, and IAST-Sips; among these, the P-factor model showed the best fitting results in predicting the influence of salinity of Ni and Zn in the binary sorption system onto IOCS and MOCS. IOCS and MOCS offer a sustainable reactive media in a permeable reactive barrier (PRB) for removing Ni and Zn in the presence of salinity. | Choi, Jiyeon; Septian, Ardie; Shin, Won Sik | Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | ; Septian, Ardie/HGB-8696-2022 | 57211707591; 57201503612; 23019870800 | iamchoig@gmail.com;ardieseptian@knu.ac.kr;wshin@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 12 | 14 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2020 | 3.251 | 45.1 | 0.49 | 2025-06-25 | 8 | 8 | binary sorption; heavy metals; IOCS; MOCS; salinity | PERMEABLE REACTIVE BARRIER; AQUEOUS-SOLUTION; COMPETITIVE SORPTION; HEAVY-METAL; ADSORPTION; GROUNDWATER; WATER; NICKEL; COPPER; IONS | Binary sorption; Heavy metals; IOCS; MOCS; Salinity | adsorption; cation exchange capacity; experimental study; iron oxide; isotherm; manganese oxide; nickel; reactive barrier; salinity; surface area; zinc | English | 2020 | 2020-07 | 10.3390/su12145815 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Application of polyethylenimine-coated magnetic nanocomposites for the selective separation of Cs-enriched clay particles from radioactive soil | The separation of Cs-enriched fine particles is a highly effective way to reduce the volume and radioactivity of contaminated soil. This work demonstrated the application of polyethylenimine (PEI)-coated Fe(3)O(4)nanocomposites and a mesh filter for the selective separation of clay particles from Cs-contaminated soil. The PEI coating on the Fe(3)O(4)nanoparticles enhanced the binding force between the magnetic nanoparticles and clay mineralsviaelectrostatic attraction; thus, approximately 100% of the clay particles were magnetically separated from solution by Fe3O4-PEI nanocomposites at a low dose (0.04 g-nanocomposite per g-clay). In separation experiments with soil mixtures, clay- and silt-sized fine particles that had been magnetized by Fe3O4-PEI nanocomposites were selectively separated, and the separation efficiency improved when a mesh filter was added to exclude physically large particles. The combination of magnetic and sieving separation thoroughly separated fine particles from soil by reducing the volume of the magnetic fraction. We also evaluated the magnetic-sieving separation method for the selective removal of clay particles from(137)Cs-contaminated soil. The decrease in radioactivity in the treated nonmagnetic fraction, which accounted for 87.5% of the total soil, corresponded to a high decontamination efficiency of approximately 90%. The developed separation technology offers great potential for the efficient remediation of radioactive soil. | Kim, June-Hyun; Kim, Sung-Man; Yoon, In-Ho; Kim, Ilgook | Korea Atom Energy Res Inst, Decommissioning Technol Res Div, 111,Daedeak Daera 989 Bean Gil, Daejeon 305353, South Korea; KyungPook Natl Univ, Sch Architectural Civil Environm & Energy Engn, 80 Daehak Ro, Daegu, South Korea | Yoon, In-Ho/S-2386-2017 | 57211214201; 57211217712; 8527138200; 56449775700 | ilgook@kaeri.re.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 10 | 37 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 3.361 | 45.2 | 0.49 | 2025-06-25 | 11 | 14 | CESIUM; FUKUSHIMA; RADIOCESIUM; FIXATION; MINERALS; SORPTION; CONTAMINATION; FLOCCULATION; ADSORPTION; DEPOSITION | Efficiency; Iron oxides; Magnetic bubbles; Magnetic nanoparticles; Magnetite; Mesh generation; Nanocomposites; Radiation; Radiation decontamination; Radioactivity; Remediation; Separation; Soils; Contaminated soils; Magnetic nanocomposites; Polyethylenimines; Selective removal; Selective separation; Separation efficiency; Separation methods; Separation technologies; Soil pollution | English | 2020 | 2020-06-09 | 10.1039/d0ra03426f | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Automatic Optical Inspection System with Telecentric Optics and Phase-measuring Profilometry for Highly Accurate Localization of Electronic Packages | Typical visual placement inspection systems in semiconductor or electronics manufacturing industries use only highly-magnified two-dimensional imaging with controlled illumination for high accuracy. However, current semiconductor packaging technology needs more precise manufacturing processes for highly integrated semiconductor packages, in which high-precision alignment between the semiconductor die and the matched substrate is indispensable for successful electronic interconnection. To solve this problem, an advanced visual placement inspection system for 3D stacking of electronic components is proposed; it utilizes 3D profilometry and 2D telecentric optics. In addition to the introduction of the proposed system, the system calibration algorithms and the information processing algorithms for accurate positioning of the semiconductor die, as well as the implemented inspection system are described in detail. To verify the system performance, a series of real experiments on newly developed flip-chip packages for high-performance computing were performed, and the results are analyzed and discussed. | Lee, Hyunki; Kim, Min Young | DGIST, Div Intelligent Robot, 333 Techno Jungang Daero, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 1370 Sankyuk Dong, Daegu, South Korea | Lee, Eun-Hye/KDN-5679-2024 | 12787798600; 56739349100 | hklee@dgist.ac.kr;mykim@ee.knu.ac.kr; | INTERNATIONAL JOURNAL OF CONTROL AUTOMATION AND SYSTEMS | INT J CONTROL AUTOM | 1598-6446 | 2005-4092 | 18 | 8 | SCIE | AUTOMATION & CONTROL SYSTEMS | 2020 | 3.314 | 45.2 | 0.07 | 2025-06-25 | 4 | 3 | Automated optical inspection; phase-measuring profilometry; visual inspection | Automated optical inspection; phase-measuring profilometry; visual inspection | Birefringence; Chip scale packages; Electronics industry; Inspection; Inspection equipment; Profilometry; Substrates; Automatic optical inspection; Electronics manufacturing industry; High performance computing; High precision alignments; Phase measuring profilometry; Semiconductor packages; Semiconductor packaging; Two-dimensional imaging; Three dimensional integrated circuits | English | 2020 | 2020-08 | 10.1007/s12555-019-0887-6 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Design, Modeling, and Evaluation of a Compact and Lightweight Needle End-effector with Simple Force-feedback Implementation for Robotic CT-guided Needle Interventions | We present a compact and lightweight two degrees-of-freedom (DOF) needle end-effector to be applied to a teleoperated needle interventional robotic system. The suggested needle end-effector is computerized tomography (CT)-compatible and easy to sterilize. Because the proposed needle end-effector can be attached to a robotic manipulator, the needle can translate into and rotate in the human body. In addition, a 1-axis load cell is attached to the needle end-effector to measure the longitudinal force applied to the needle. With this force measurement, force-feedback ability has been implemented in the entire master-slave robotic system. Basic performance tests of repeatability and maximum insertion force were performed. Several force-feedback experiments to determine free space response and contact response, as well as a discrimination test, were conducted. Through this verification process, the suggested needle end-effector was found to have potential for application in real environments that require robotic CT-guided needle interventions. | Kim, Kiyoung; Woo, Hyunsoo; Cho, Jang Ho; Suh, Jungwook | KIMM, Dept Med Assistant Robot, 330 Techno Sunhwan Ro, Daegu 42994, South Korea; Kyungpook Natl Univ, Dept Robot & Smart Syst Engn, 80 Daehakro, Daegu 41566, South Korea | 57201688619; 8551464000; 7403536244; 36606826500 | kiyoung@kimm.re.kr;woohs@kimm.re.kr;jangho@kimm.re.kr;jwsuh@knu.ac.kr; | INTERNATIONAL JOURNAL OF CONTROL AUTOMATION AND SYSTEMS | INT J CONTROL AUTOM | 1598-6446 | 2005-4092 | 18 | 1 | SCIE | AUTOMATION & CONTROL SYSTEMS | 2020 | 3.314 | 45.2 | 0.34 | 2025-06-25 | 6 | 7 | Force-feedback; medical robot; needle end-effector; robotic CT-guided intervention | PNEUMATIC ROBOT; BRACHYTHERAPY; SYSTEM | Force-feedback; medical robot; needle end-effector; robotic CT-guided intervention | Computerized tomography; Degrees of freedom (mechanics); Feedback; Manipulators; Needles; Robotics; Discrimination tests; Force feedback; Longitudinal force; Master-slave robotic systems; Medical robots; Robotic manipulators; Two degrees of freedom; Verification process; End effectors | English | 2020 | 2020-01 | 10.1007/s12555-019-0235-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of a tablet PC-based portable device for colorimetric determination of assays including COVID-19 and other pathogenic microorganisms | There has been a strong and urgent demand to diagnose community transmission-driven coronavirus disease 2019 (COVID-19) after it crossed borders. A large number of rapid and accurate tests and diagnoses are required at drive-through test stations, community clinics and hospitals. Isothermal amplification technology, such as loop-mediated isothermal amplification (LAMP) and recombinase polymerase amplification (RPA), provides excellent alternatives for resource limited test environments. LAMP has been shown to be comparable with polymerase chain reaction (PCR) and can be performed in less than 30 min by non-laboratory staff without ribonucleic acid (RNA) extractions commonly associated with PCR. LAMP tests on assays with SARS-CoV-2 and other pathogenic microorganisms, such as Dengue, Malaria, and Influenza viruses andHelicobacter pylorishow color changes allowing test results to be interpreted by the color change of the assays. However, visual inspection of a large number of assays is prone to human error and manual record keeping makes test result tracking for an epidemiologic investigation very difficult and inefficient. The epidemiologic investigation is an essential part of the fight against community transmission-driven viruses. We have developed a very accurate and reliable, human error free, tablet PC-based portable device for colorimetric determination of assays including SARS-CoV-2 and other pathogenic microorganisms. | Yoo, Woo Sik; Han, Hyung Soo; Kim, Jung Gon; Kang, Kitaek; Jeon, Hyo-Sung; Moon, Jin-Young; Park, Hyeonmi | WaferMasters Inc, Dublin, CA 94568 USA; Kyungpook Natl Univ, Sch Med, Clin Omics Inst, Dept Physiol, Daegu, South Korea; M Monitor Inc, Daegu 47213, South Korea | 55665974300; 7401969388; 48161606000; 9638686700; 59108838200; 57218992597; 57219002614 | woosik.yoo@wafermasters.com; | RSC ADVANCES | RSC ADV | 2046-2069 | 10 | 54 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 3.361 | 45.2 | 0.79 | 2025-06-25 | 10 | 15 | ENZYMATIC AMPLIFICATION | Color; Colorimetry; Diagnosis; Diseases; Errors; Isotherms; Personal computers; Portable equipment; Records management; RNA; Testing; Transmissions; Viruses; Colorimetric deter-mination; Influenza virus; Isothermal amplifications; Loop mediated isothermal amplifications; Pathogenic microorganisms; Portable device; Test Environment; Visual inspection; Polymerase chain reaction | English | 2020 | 2020-09-06 | 10.1039/d0ra05866a | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Estimation of Slag Removal Path using CNN-based Path Probability of Ladle Image Blocks | De-slagging is a task of removing slag on the surface of molten metals, such as steel, in a ladle. In this paper, we propose a method of slag removal path estimation using CNN (Convolution Neural Network) to automate de-slagging task using a robotic machine. From a sequence on images captured from the top of the ladle, we first extract the 2-dimensional trajectory of the slag removal motion of an experienced human operator. Then several image blocks are obtained at sample points along the removal trajectory to train a neural network. The output of the network consists of four labels which represent the probability of four different removal directions of an input image block. To test the trained neural network, we uniformly divide a test ladle image to a fixed-size block with a given stride value. All image blocks are tested and the probability of the four directions are determined and recorded by the trained network. By multiplying the slag probability with the removal direction probability, joint probability of slag removal direction (JPSRD) is introduced. Finally, a slag removal path is estimated by applying the backward tracing method from the endpoint of the ladle so that the estimated path yields the highest JPSRD. A curve fitting is then applied to make smooth slag removal path. The path decision accuracy of an image block is about 90%. We also compare the estimated a slag removal path with that of the experienced operator. | Kim, Jeong-Soo; Ahn, Geon-Tae; Park, Soon-Yong | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Res Inst Ind Sci & Technol Pohang, Pohang, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Park, Soon-Yong/HGV-2374-2022 | 57211457328; 56559578600; 7501834063 | hot1074@naver.com;seeahn@rist.re.kr;sypark@knu.ac.kr; | INTERNATIONAL JOURNAL OF CONTROL AUTOMATION AND SYSTEMS | INT J CONTROL AUTOM | 1598-6446 | 2005-4092 | 18 | 3 | SCIE | AUTOMATION & CONTROL SYSTEMS | 2020 | 3.314 | 45.2 | 0.2 | 2025-06-25 | 5 | 5 | Backward tracing; convolutional neural network; direction probability; image block; slag removal | Backward tracing; convolutional neural network; direction probability; image block; slag removal | Convolution; Curve fitting; Ladles; Liquid metals; Neural networks; Probability; Backward tracing; Convolution neural network; Convolutional neural network; Decision accuracies; Image blocks; Joint probability; Path probability; Trained neural networks; Slags | English | 2020 | 2020-03 | 10.1007/s12555-019-0019-3 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Formation of arsenic clusters in InAs nanowires with an Al2O3shell | An in-depth understanding of thermal behavior and phase evolution is required to apply heterostructured nanowires (NWs) in real devices. The intermediate status during the vaporization process of InAs NWs in an Al2O3shell was studied by conducting quenching duringin situheating experiments, using a transmission electron microscope. The formation of As clusters in the amorphous Al2O3shell was confirmed by analyzing the high-angle annular dark field images and energy-dispersive X-ray spectra. The As clusters existed independently in the shell and were also observed at the end of the InAs pieces obtained after quenching. The formation process of the As clusters was demonstrated from a theoretical perspective. Moreover, anab initiomolecular dynamics simulation (AIMD) was conducted to study the atomic and molecular behaviors. © The Royal Society of Chemistry 2020. | Kim, In; Choi, Suji; Kwon, Ji-Hwan; Ahn, Sang Jung; Yeom, Min Sun; Lee, Ho Seong; Yi, Seong-Hoon; Kim, Young Heon | Center for Supercomputing Applications, Korea Institute of Science and Technology Information, 245 Daehak-ro, Daejeon, 34141, South Korea; Korea Research Institute of Standards and Science, 267 Gajeong-Ro, Yuseong-Gu, Daejeon, 34113, South Korea, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Korea Research Institute of Standards and Science, 267 Gajeong-Ro, Yuseong-Gu, Daejeon, 34113, South Korea; Korea Research Institute of Standards and Science, 267 Gajeong-Ro, Yuseong-Gu, Daejeon, 34113, South Korea; Center for Supercomputing Applications, Korea Institute of Science and Technology Information, 245 Daehak-ro, Daejeon, 34141, South Korea; Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Graduate School of Analytical Science and Technology (GRAST), Chungnam National University, 99 Daehak-ro, Yuseong-gu, Daejeon, 34134, South Korea | 36812712200; 56424207100; 17346242700; 11241040000; 6602071477; 55706810400; 14008383000; 57196172886 | y.h.kim@cnu.ac.kr; | RSC Advances | RSC ADV | N/A | 2046-2069 | 11 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2020 | 3.361 | 45.2 | 0.06 | 2025-06-25 | 1 | Arsenic; III-V semiconductors; Indium arsenide; Nanowires; Quenching; Transmission electron microscopy; Dynamics simulation; Energy dispersive x-ray; Heterostructured Nanowires; High-angle annular dark-field images; In-depth understanding; Molecular behavior; Thermal behaviors; Vaporization process; Aluminum compounds | English | Final | 2020 | 10.1039/d0ra06505f | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Article | In vitro synergistic potentials of novel antibacterial combination therapies against Salmonella enterica serovar Typhimurium | Background The antibiotics generally used in farm animals are rapidly losing their effectiveness all over the world as bacteria develop antibiotic resistance. Like some other pathogenic bacteria multidrug-resistant strains of Salmonella enterica serovar Typhimurium (S. Typhimurium) are also frequently found in animals and humans which poses a major public health concern. New strategies are needed to block the development of resistance and to prolong the life of traditional antibiotics. Thus, this study aimed to increase the efficacy of existing antibiotics against S. Typhimurium by combining them with opportunistic phenolic compounds gallic acid (GA), epicatechin, epicatechin gallate, epigallocatechin and hamamelitannin. Fractional inhibitory concentration indexes (FICI) of phenolic compound-antibiotic combinations against S. Typhimurium were determined. Based on the FICI and clinical importance, 1 combination (GA and ceftiofur) was selected for evaluating its effects on the virulence factors of this bacterium. Viability of Rattus norvegicus (IEC-6) cell in presence of this antibacterial combination was evaluated. Results Minimum inhibitory concentrations (MICs) of GA, epigallocatechin and hamamelitannin found against different strains of S. Typhimurium were 256, (512-1024), and (512-1024) mu g/mL, respectively. Synergistic antibacterial effect was obtained from the combination of erythromycin-epicatechin gallate (FICI: 0.50) against S. Typhimurium. Moreover, additive effects (FICI: 0.502-0.750) were obtained from 16 combinations against this bacterium. The time-kill assay and ultrastructural morphology showed that GA-ceftiofur combination more efficiently inhibited the growth of S. Typhimurium compared to individual antimicrobials. Biofilm viability, and swimming and swarming motilities of S. Typhimurium in presence of GA-ceftiofur combination were more competently inhibited than individual antimicrobials. Viabilities of IEC-6 cells were more significantly enhanced by GA-ceftiofur combinations than these antibacterials alone. Conclusions This study suggests that GA-ceftiofur combination can be potential medication to treat S. Typhimurium-associated diarrhea and prevent S. Typhimurium-associated blood-stream infections (e.g.: fever) in farm animals, and ultimately its transmission from animal to human. Further in vivo study to confirm these effects and safety profiles in farm animal should be undertaken for establishing these combinations as medications. | Hossain, Md.

| ○ | ○ | Article | Neur1andNeur2are required for hippocampus-dependent spatial memory and synaptic plasticity | Neur1andNeur2, mouse homologs of theDrosophila neurgene, consist of two neuralized homology repeat domains and a RING domain. BothNeur1andNeur2are expressed in the whole adult brain and encode E3 ubiquitin ligases, which play a crucial role in the Notch signaling pathways. A previous study reported that overexpression ofNeur1enhances hippocampus-dependent memory, whereas the role ofNeur2remains largely unknown. Here, we aimed to elucidate the respective roles ofNeur1andNeur2in hippocampus-dependent memory using three lines of genetically modified mice:Neur1knock-out,Neur2knock-out, andNeur1andNeur2double knock-out (D-KO). Our results showed that spatial memory was impaired when bothNeur1andNeur2were deleted, but not in the individual knock-out of eitherNeur1orNeur2. In addition, basal synaptic properties estimated by input-output relationships and paired-pulse facilitation did not change, but a form of long-term potentiation that requires protein synthesis was specifically impaired in the D-KO mice. These results collectively suggest thatNeur1andNeur2are crucially involved in hippocampus-dependent spatial memory and synaptic plasticity. | Lee, Jaehyun; Yoon, Ki-Jun; Park, Pojeong; Lee, Chaery; Kim, Min Jung; Han, Dae Hee; Kim, Ji-il; Kim, Somi; Lee, Hye-Ryeon; Lee, Yeseul; Jang, Eun-Hae; Ko, Hyoung-Gon; Kong, Young-Yun; Kaang, Bong-Kiun | Seoul Natl Univ, Interdisciplinary Program Neurosci, Seoul, South Korea; Korea Adv Inst Sci & Technol KAIST, Dept Biol Sci, Daejeon, South Korea; Seoul Natl Univ, Coll Nat Sci, Sch Biol Sci, Neurobiol Lab, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Anat & Neurobiol, Daegu, South Korea; Seoul Natl Univ, Coll Nat Sci, Sch Biol Sci, 1 Gwanangno, Seoul 08826, South Korea | ; park, pojeong/AAT-1716-2021; Yoon, Ki-Jun/S-8170-2018; Ko, Hyoung-Gon/KQU-8680-2024 | 57203144612; 36833918700; 55944871400; 59873512400; 57839629300; 57203166129; 56924106100; 57200557270; 54899849700; 56477456700; 59853258800; 14522654800; 7201616022; 7003889686 | ykong@snu.ac.kr;kaang@snu.ac.kr; | HIPPOCAMPUS | HIPPOCAMPUS | 1050-9631 | 1098-1063 | 30 | 11 | SCIE | NEUROSCIENCES | 2020 | 3.899 | 45.2 | 0.13 | 2025-06-25 | 3 | 4 | E3 ligase; hippocampus-dependent learning and memory; long-term potentiation; Neur1; Neur2; spatial memory; synaptic plasticity; ubiquitination | DROSOPHILA NEURALIZED GENE; LONG-TERM POTENTIATION; E3 UBIQUITIN LIGASE; NOTCH LIGAND; HOMOLOG; PROTEIN; FEAR; MECHANISMS; NAVIGATION; CELLS | E3 ligase; hippocampus-dependent learning and memory; long-term potentiation; Neur1; Neur2; spatial memory; synaptic plasticity; ubiquitination | Animals; Female; Hippocampus; Male; Maze Learning; Mice; Mice, Inbred C57BL; Mice, Knockout; Nerve Tissue Proteins; Neuronal Plasticity; Repressor Proteins; Spatial Memory; Ubiquitin-Protein Ligase Complexes; brain protein; neuralized 1; neuralized 2; ubiquitin protein ligase; unclassified drug; nerve protein; Neurl protein, mouse; Neurl2 protein, mouse; repressor protein; ubiquitin protein ligase; animal experiment; Article; controlled study; escape latency; fear conditioning test; female; genetic background; genotype; hippocampus; knockout mouse; long term memory; long term potentiation; male; mouse; nerve cell plasticity; nonhuman; post hoc analysis; priority journal; protein synthesis; spatial memory; swimming speed; working memory; Y-maze test; animal; C57BL mouse; genetics; hippocampus; maze test; metabolism; nerve cell plasticity; physiology; spatial memory | English | 2020 | 2020-11 | 10.1002/hipo.23247 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
