| ○ | ○ | Article | Norbornene and methyl methacrylate polymerizations catalyzed by palladium(II) complexes bearing aminomethylpyridine and aminomethylquinoline derivatives | A series of Pd(II) complexes, 1-4 bearing N,N-bidentate aminomethylpyridine and aminomethylquinoline derivatives were synthesized and characterized. Single crystal X-ray diffraction analysis demonstrated that tetra-coordinated Pd(II) complexes adopted distorted square planar geometries around the metal center. In the presence of modified methylaluminoxane (MMAO) as a co-catalyst, Pd(II) complexes 1-4 exhibited significant activities (up to 43.2 x 10(5) g(PNB) mol Pd-1 h(-1)) towards the addition polymerization of norbornene (NB) at 25 degrees C. Insoluble poly(norbornene) (PNB) was obtained by all the tested catalytic systems, i.e., 1-4/MMAO. The catalytic capabilities of synthesized Pd(II) complexes were also tested towards methyl methacrylate (MMA) in the presence of modified methyl aluminoxane MMAO. Complex 3 with quinoline/piperidine functionalities showed the highest catalytic activity of 8.83 x 10(4) g(PMMA) mol Pd-1 h(-1) at 60 degrees C and resulted in high molecular weight PMMA (M-w = 2.16 x 10(6) g mol(-1)). All the complexes yielded syndiotactic poly(methyl methacrylate) (PMMA) (rr = 0.70). Notably, the steric bulk and electronic properties of the ligand framework affect their activities towards NB and MMA polymerizations, whereas, for PMMA, the stereoselectivities remained unaffected.

| ○ | ○ | Article | Two-dimensional zinc(II) and copper(I) coordination polymers for photoluminescence | Two-dimensional (2-D) coordination polymers [Zn-2(bpab)(CH3CO2)(4)]center dot H2O (1), [Zn(bpab)(H2O)(2)](NO3)(2) (2), [Cu-2(bpab)I-2]center dot CH3OH (3), and [Cu-2(tpmd)I-2] (4) have been synthesized by the reaction of zinc(II)/copper(I) ions and tetradentate polypyridine ligands (bpab = bis-1,4-(di-4-pyridylaminomethyl)benzene and tpmd = N,N,N',N'-tetrakis(pyridine-4-yl)methanediamine). The zinc(II) ions of 1 and 2 have distorted tetrahedral and trigonal bipyramidal geometries, respectively. By coordinating zinc(II) ions and bpab ligands, 1 and 2 formed a brick wall and puckered 2-D networks, respectively. The copper(I) ions of 3 and 4 are both tetrahedral structures with Cu2I2 rhomboidal geometry. By linking the Cu2I2 cores and bpab/tpmd ligands, 3 and 4 exhibited interwoven and interconnected bilayered 2-D networks, respectively. Compared to free bpab and tpmd ligands, polymers 1 and 2 show strongly blue-shifted emissions, whereas polymers 3 and 4 show strongly red-shifted emissions. Therefore, the shifts of emission wavelengths are strongly dependent on the zinc(II) and copper(I) ions that linked the bpab/tpmd tetradentate ligands, respectively. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Economic indicators and bioenergy supply in developed economies: QROF-DEMATEL and random forest models | Bioenergy is a renewable energy source that saves from fossil fuel dependence. Therefore, it is important to increase the efficiency of bioenergy investments to create an environmentally sustainable energy supply. This paper aims to identify economic indicators significant in forecasting the supply of bioenergy. Considering this goal, an integrated evaluation has been performed for 17 developed economies using the Random Forest method and the Fuzzy Decision-Making Trial and Evaluation Laboratory (QROF-DEMATEL) method. The main contribution of this study is conducting analysis by using both quantitative and qualitative data. Additionally, the coherence of the results made with the QROF-DEMATEL method is also verified by implementing a sensitivity analysis. The results of both approaches are quite similar and provide information about the reliability of the findings. This situation demonstrates that for the development of bioenergy investments, firstly, countries' macroeconomic conditions should be improved. Consequently, economic growth and unemployment (weighting results -0.159 and 0.155) should be primarily considered for the bioenergy supply forecast. (c) 2021 The Author(s).

| ○ | ○ | Article | No More Strategical Neutrality on Technological Neutrality: Technological Neutrality as a Bridge Between the Analogue Trading Regime and Digital Trade | The World Trade Organization (WTO), a unique multilateral trading regime, has failed to establish its relevance to the digital nature of trade. This article revisits the 'principle of technological neutrality' to make the cross-border supply of services by electronic means subject to the current rules-based trading regime. I argue that the principle of technological neutrality could help resolve a number of thorny legal issues: confirming the applicability of the General Agreement on Trade in Services (GATS) rules to the delivery of services by electronic means; providing a guideline to determine the likeness of services in the era of digital trade; and backing up an evolutionary approach to interpreting the GATS schedules of commitments. However, the WTO adjudicatory bodies have been reluctant to rely on the principle of technological neutrality, which is referred to as strategic neutrality in this article. This article urges the WTO adjudicatory bodies to abandon their strategically neutral position on technological neutrality immediately. It also explores ways to incorporate the principle of technological neutrality into the world trading system at the bilateral, plurilateral, and multilateral levels. | Kwak, Dongchul | Kyungpook Natl Univ, Sch Econ & Trade, Daegu, South Korea | 57217296158 | kwakdc@knu.ac.kr; | WORLD TRADE REVIEW | WORLD TRADE REV | 1474-7456 | 1475-3138 | 21 | 1 | SSCI | ECONOMICS;INTERNATIONAL RELATIONS;LAW | 2022 | 1.3 | 45.8 | 0.98 | 2025-06-25 | 2 | 5 | Technological neutrality; international trade law; digital trade; GATS; likeness | LAW | digital trade; GATS; international trade law; likeness; Technological neutrality | English | 2022 | 2022-02 | 10.1017/s1474745620000580 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | On improving seismic risk and cost for nuclear energy facility based on multi-objective optimization considering seismic correlation | Currently, the system, structure, and component (SSC) seismic design and seismic probabilistic safety assessment (SPSA) process for the nuclear energy facility are performed individually, thus seismic risk reduction and cost efficiency cannot be pursued. Accordingly, this study proposes a method to determine the seismic design margin of SSCs of nuclear research reactor (RR) by minimizing seismic risk and cost simultaneously. To concurrently minimize the two conflicting goals of risk and cost, a multi-objective optimization (MOO) method is introduced. Also, such a method includes considering seismic correlations between SSCs for the accurate risk assessment. An improved sampling-based seismic risk assessment technique is proposed and combined with the MOO method to efficiently consider the seismic correlation between SSCs. As a result, Pareto-optimal solutions which minimized the seismic risk and cost of the existing RR were derived by applying the proposed method. These optimal solutions reduced up to 25% in seismic risk or up to 30% in cost compared to the existing one. Also, the proposed sampling-based risk method secured efficiency compared to the existing method. Consequently, the novelty of this study lies in the development of a method for determining the seismic margin of the SSC design based on the multi-objective optimization technique combined with the enhanced SPSA, and the improvement of costs and risks to the existing RR.

| ○ | ○ | Article | Performance evaluation of two grid-connected solar photovoltaic systems under temperate climatic conditions in South Korea | This study evaluates two grid-connected solar photovoltaic (PV) systems using five criteria: final energy output, system yield, performance ratio, capacity factor, and system efficiency. The PV systems were installed on the rooftop of the Engineering building, Kyungpook National University, the Republic of Korea. The system was monitored, and necessary environmental data was recorded from January 2021 to December 2021. From the result, the annual electricity exported to the grid by the m-si solar PV was 9521 kWh, and that of the p-si was 8263 kWh. The m-si has a better annual average daily final and array yield of 5.23 h/day and 5.45 h/day than the annual final and array yield of p-si with 4.93 h/day and 5.12 h/day, respectively The composite solar PV saved the environment from 9.7 tons of CO2per year, equivalent to 9.7% of people reducing energy use by 20%. Based on the analysis for this location, the m-si solar cell technology showed a better annual performance than the p-si solar cell when considering the five evaluations, except for the performance ratio where the p-si solar cell outperformed the m-si solar technology. Finally, this study provides insightful information to researchers, PV installers, and PV manufacturing companies on the actual performance of grid-connected solar PV in Korea.

| ○ | ○ | Article | Shape-stabilized orange peel/myristic acid phase change materials for efficient thermal energy storage application | An environmentally techno, reasonably viable waste utilization is vital for the sustainability of human civilization. In view of that, orange peel (OP) has been considered for this study to utilize as organic waste materials for thermal energy storage application. OP has been pyrolyzed into porous biochar and has been used for the shape stabilization of myristic acid (MA) as phase change materials (PCMs). MA has been loaded in different content inside orange peel biochar and thermal stability and performance of the synthesized PCMs (MAOP samples) have been studied for their suitable applications. Biochar to MA ratio at 1:4 has been found to be optimum for the maximum accommodation of the MA in biochar pores. The highest encapsulation ratio and efficiency have been found 39.60% and 39.13%, respectively whereas the maximum heat storage capability has been found to be 67.2 J/g. Excellent performance against leakage during phase transition and congruent thermal cycle stability have been manifested by all MAOP samples. The superior properties demonstrated by the MAOP samples are attributed to the capillary action, strong surface tension, and space confinement effects offered by the porous structures and the surface functionalities of the biochar.

| ○ | ○ | Article | Adsorption behavior of kenyaite for Cu²⁺ and Pb²⁺ | Hydrated layered polysilicates (HLPSs) have received considerable attention as adsorbents because of their selective adsorption for heavy metal cations. However, the adsorption behavior of kenyaite, a HLPS, was not elucidated for heavy metal cations yet. The aim of this study is to investigate adsorption behavior of kenyaite for various heavy metal cations and to elucidate selective adsorption. In the quaternary Cu-Pb-Cd-Zn system, kenyaite exhibited selective adsorption, especially for Pb2+ and Cu2+ of which removal rates were 97 and 66%, respectively. It revealed that Pb2+ was more strongly adsorbed than Cu2+ through coordination with interlayer silanol groups, resulting in dehydration in the interlayers and severe collapse of the silicate layers. In the presence of NaCl, on the other hand, adsorption for Cu2+ was less affected showing removal rate of 56% whereas that for Pb2+ was considerably affected as indicated by remarkably decreased removal rate (42%). Such a preferential adsorption of Cu2+ in the presence of NaCl could be explained by the role of interlayer Na+ in inhibiting rapid collapse of the interlayer space to facilitate more adsorption of Cu2+ with a larger hydrated radius. This study provides an insight into understanding selective adsorption of HLPSs and developing potential adsorbents for water purification. | Fatima, Hina; Seo, Jae-Deok; Kim, Junhyung; Park, Man | Kyungpook Natl Univ, Coll Agr & Life Sci, Lab Soil Sci, 80 Daehakro, Daegu 41566, South Korea | 59800323300; 57216441278; 56178833600; 36871192900 | manpark@knu.ac.kr; | JOURNAL OF POROUS MATERIALS | J POROUS MAT | 1380-2224 | 1573-4854 | 29 | 1 | SCIE | CHEMISTRY, APPLIED;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 2.6 | 45.9 | 0.62 | 2025-06-25 | 8 | 8 | Kenyaite; Polysilicate; Selective adsorption; Heavy metal | LAYERED SILICATES; AQUEOUS-SOLUTION; MAGADIITE; NMR; EXCHANGE; REMOVAL; IONS | Heavy metal; Kenyaite; Polysilicate; Selective adsorption | Copper compounds; Heavy metals; Hydration; Positive ions; Silicates; Sodium chloride; Adsorption behavior; Heavy metal cations; Interlayer spaces; Potential adsorbents; Preferential adsorption; Selective adsorption; Silicate layers; Water purification; Adsorption | English | 2022 | 2022-02 | 10.1007/s10934-021-01140-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bicortical Laminar Screws for Posterior Fixation of Subaxial Cervical Spine: A Radiologic Analysis With Computed Tomography Images | Study Design: Retrospective radiological analysis. Objectives: Translaminar screw (TLS) placement is one of the fixation techniques in the subaxial cervical spine. However, it can be difficult to use in small diameter of the lamina. This study proposed a novel bicortical laminar screw (BLS) and analyzed the related parameters using computed tomography (CT). Methods: Cervical CT images taken at our institution from January 2013 to March 2017 were used for measurement. On the axial images, the maximum screw length (MSL) and trajectory angle (TA) of BLS and TLS were measured, together with the distance from the midline (DM) to the BLS entry point and the lamina width (LW). On the parasagittal images, the height of the lamina (LH) was measured. Results: MSL of BLS and TLS were 21.00 and 20.97 mm, 19.02 and 20.91 mm, 18.45 and 21.01 mm, and 20.00 and 21.01 mm in C3, C4, C5, and C6, respectively. TA of the BLS and TLS were 21.24 degrees and 34.90 degrees, 19.05 degrees and 34.22 degrees, 18.65 degrees and 33.61 degrees, and 18.30 degrees and 34.51 degrees at C3, C4, C5, and C6, respectively. DM were 6.44, 5.77, 5.68, and 6.03 at C3, C4, C5, and C6, respectively. LW and LH were 3.52 and 12.44 mm, 2.87 and 12.49 mm, 2.76 and 12.42 mm, and 3.18 and 13.30 mm at C3, C4, C5, and C6, respectively. Conclusion: We suggest that BLS fixation is a feasible alternative option for posterior fixation to the lamina of the subaxial cervical spine. It may be especially useful when pedicle screw, lateral mass screw, and TLS are not appropriate. | Park, Eugene J.; Min, Woo-Kie; Sim, Seungbo | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Daegu, South Korea | ; Park, Eugene/P-1473-2018 | 55371642100; 8548041000; 58587466700 | oswkmin@gmail.com; | GLOBAL SPINE JOURNAL | GLOB SPINE J | 2192-5682 | 2192-5690 | 12 | 1 | SCIE | CLINICAL NEUROLOGY;ORTHOPEDICS | 2022 | 2.4 | 45.9 | 0.16 | 2025-06-25 | 1 | 1 | subaxial cervical spine; bicortical laminar screw; posterior instrumentation | FEASIBILITY; C2; PLACEMENT | bicortical laminar screw; posterior instrumentation; subaxial cervical spine | luteinizing hormone; adult; Article; cervical spine; cervical vertebra; computer assisted tomography; cortical bone; female; fifth cervical vertebra; fourth cervical vertebra; fracture fixation; human; major clinical study; male; middle aged; musculoskeletal system parameters; retrospective study; sixth cervical vertebra; spine injury; third cervical vertebra; x-ray computed tomography | English | 2022 | 2022-01 | 10.1177/2192568220947054 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Examine the Mechanical Properties of Aluminium Tetrahydride/Calotropis gigantea Based Hybrid Polyester Composites in Cryogenic Atmosphere | From the previous scarce periods, the investigation has evolved from traditional resources and compounds and toward frivolous constituents to produce small and hugely influential substances for specific purposes. The foremost goal of the current examination is to explore the effectiveness of aluminium tetrahydride (ATH) filler addition on the Calotropis gigantea fibre (CGF)/polyester-based hybrid composite. The hybrid materials with a 3 mm width and three layers of CGF were manufactured using the conventional technique. To achieve the objectives mentioned above, the following constraints like (i) Wt.% of ATH, (ii) number of CGF Layers, and (iii) cryogenic treatment hours, each at three different levels, were chosen. The composite was fabricated as per the design of L-9 orthogonal array. This research measured the mechanical characteristics like flexural, tensile, and impact characteristics. The materials with 5 wt proportions of filler, 3 layers of CGF and 30 min of liquid nitrogen treatment (A2, B3 and C2) showed better mechanical strength. They were studying the broken specimen's morphological behavior by scanning electron microscopy (SEM). | Bagali, Pavan Balappa; Rashid, N. I.

For the adsorption of cyclopentane into H-ZSM-5 crystal, the crystal was treated with zeolitically dried cyclopentane for 6 h at 297 K, and then evacuated for 600 s at this temperature and 1.1 x 10(-4) Pa. The structure of a single crystal of cyclopentane sorption complex of dehydrated H-ZSM-5 (MFI, |H-3.8(C5H10)(1.47)|[Al3.8Si92.2O192]-MFI, Si/Al = 24) has been determined crystallographically using synchrotron X-radiation in the orthorhombic space group Pnma; a = 20.141(4), b = 19.944(4), c = 13.439(3) angstrom. It was refined using all intensities to the final error indice R-1 = 0.072. The 1.47 cyclopentane molecules per unit cell are located between 5-rings in zigzag channel. The cyclopentane molecules are located perpendicular to the 10-rings of zigzag channel and parallel to the 5-rings of H-ZSM-5 framework at the center of them. Each cyclopentane molecule is held in place by 16 hydrogen bonds between all hydrogen atoms of cyclopentane and framework oxygen atoms of its 5- and 10-rings: C center dot center dot center dot O ca. 3.318 similar to 3.992 angstrom. | Kim, Jong Jin; Nath, Sayantika; Yim, Bong Been; Lee, Hyun-Jae; Kim, Hu Sik; Heo, Nam Ho; Lim, Woo Taik | Enbion Inc, 275,Techno 2 Ro, Daejeon 34026, South Korea; Andong Natl Univ, Dept Appl Chem, Andong 36729, South Korea; Kyungpook Natl Univ, Coll Engn, Dept Appl Chem, Daegu 41566, South Korea | Nath, Sukhendu/ABH-2854-2020 | 57217044299; 57235751700; 57217049674; 57217046492; 35074243300; 17136916900; 7202378245 | nhheo@knu.ac.kr;wtlim@anu.ac.kr; | JOURNAL OF POROUS MATERIALS | J POROUS MAT | 1380-2224 | 1573-4854 | 29 | 1 | SCIE | CHEMISTRY, APPLIED;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2022 | 2.6 | 45.9 | 0 | 2025-06-25 | 0 | 0 | ZSM-5; Cyclopentane; Crystal Structure; Adsorption | SINGLE-CRYSTAL STRUCTURE; ZEOLITE H-ZSM-5; ADSORPTION; BENZENE; XYLENE; DESORPTION; LOCATION; ZSM-5 | Adsorption; Crystal Structure; Cyclopentane; ZSM-5 | Atoms; Hydrogen bonds; Molecules; Silicon wafers; Single crystals; Sorption; Cyclopentane molecule; Hydrogen atoms; Orthorhombic space groups; Oxygen atom; Per unit; Sorption sites; Structural studies; X-radiation; Crystal structure | English | 2022 | 2022-02 | 10.1007/s10934-021-01134-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | 3D Pose Recognition System of Dump Truck for Autonomous Excavator | The purpose of an excavator is to dig up materials and load them onto heavy-duty dump trucks. Typically, an excavator is positioned at the rear of the dump truck when loading. In order to automate this process, this paper proposes a system that employs a combined stereo camera and two LiDAR sensors to determine the three-dimensional (3D) position of the truck's cargo box and to analyze its loading space. Sparse depth information acquired from the two LiDAR sensors is used to detect points on the door of the cargo box and establish the plane on its rear side. Dense depth information of the cargo box acquired from the stereo camera sensor is projected onto the plane of the box's rear to estimate its initial 3D position. In the next step, the point cloud sampled along the long shaft of the edge of the cargo box is used as the input of the Iterative Closest Point algorithm to calculate a more accurate cargo box position. The data collected from the stereo camera are then used to determine the 3D position of the cargo box and provide an estimate of the volume of the load along with the 3D position of the loading space to the excavator. In order to demonstrate the efficiency of the proposed method, a mock-up of a heavy-duty truck cargo box was created, and the volume of the load in the cargo box was analyzed. | Lee, Ju-hwan; Lee, Junesuk; Park, Soon-Yong | Kyungpook Natl Univ, Sch Comp Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect & Elect Engn, Daehak Ro 80, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; Park, Soon-Yong/HGV-2374-2022 | 57193725457; 57210786619; 7501834063 | sasinhwan@naver.com;ljs2352@gmail.com;sypark@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.44 | 2025-06-25 | 4 | 5 | autonomous excavator; 3D pose recognition; dump truck | 3D pose recognition; autonomous excavator; dump truck | English | 2022 | 2022-04 | 10.3390/app12073471 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Blockchain-Enabled Distributed Advanced Metering Infrastructure Secure Communication (BC-AMI) | The world is facing an urgent need to provide secure communication and data access control in advanced metering infrastructure (AMI) because conventional cryptographic key management and authentication protocols are at stake. The cryptography schemes entirely rely on trusted third parties (TTPs), leading to a single point of failure and increasing network overhead. In response to this inefficiency and security compromise, this study proposes a blockchain-enabled distributed AMI secure communication scheme. In the proposed work, smart contract (SC), an integrated part of the blockchain, is programmed to substitute traditional TTP-based transaction systems, which operate in a distributed, immutable, and trustworthy manner. In this paper, we implemented practical Byzantine fault tolerance (PBFT) consensus algorithm and Hyperledger Fabric (HLF) blockchain platform to ensure Byzantine fault tolerance in the blockchain transaction. Performance analysis shows that the proposed BC-AMI scheme has the advantage of incurring the least amount of communication and time costs compared with similar studies while ensuring security against some common cyber-attacks. | Islam, Nahida; Rahman, Sazzadur; Mahmud, Imtiaz; Sifat, Nur Amin; Cho, You-Ze | Jahangirnagar Univ, Inst Informat Technol, Dhaka 1342, Bangladesh; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Daffodil Int Univ, Dept Comp Sci & Engn, Daffodil Smart City 1207, Bangladesh | Islam, Nahida/HPD-2616-2023; Mahmud, Imtiaz/R-1089-2019 | 57221112163; 59860333500; 56203487900; 57877400600; 7404469829 | nahida11.islam@gmail.com;sazzad@juniv.edu;imtiaz@knu.ac.kr;mdnuraminsifat380@gmail.com;yzcho@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 14 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 1.4 | 2025-06-25 | 7 | 16 | advanced metering infrastructure secure communication; smart contract; hyperledger fabric; practical byzantine fault tolerance | SCHEME | advanced metering infrastructure secure communication; hyperledger fabric; practical byzantine fault tolerance; smart contract | English | 2022 | 2022-07 | 10.3390/app12147274 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | A Deep Learning Ensemble Method to Visual Acuity Measurement Using Fundus Images | Visual acuity (VA) is a measure of the ability to distinguish shapes and details of objects at a given distance and is a measure of the spatial resolution of the visual system. Vision is one of the basic health indicators closely related to a person's quality of life. It is one of the first basic tests done when an eye disease develops. VA is usually measured by using a Snellen chart or E-chart from a specific distance. However, in some cases, such as the unconsciousness of patients or diseases, i.e., dementia, it can be impossible to measure the VA using such traditional chart-based methodologies. This paper provides a machine learning-based VA measurement methodology that determines VA only based on fundus images. In particular, the levels of VA, conventionally divided into 11 levels, are grouped into four classes and three machine learning algorithms, one SVM model and two CNN models, are combined into an ensemble method in order to predict the corresponding VA level from a fundus image. Based on a performance evaluation conducted using randomly selected 4000 fundus images, we confirm that our ensemble method can estimate with 82.4% of the average accuracy for four classes of VA levels, in which each class of Class 1 to Class 4 identifies the level of VA with 88.5%, 58.8%, 88%, and 94.3%, respectively. To the best of our knowledge, this is the first paper on VA measurements based on fundus images using deep machine learning. | Kim, Jin Hyun; Jo, Eunah; Ryu, Seungjae; Nam, Sohee; Song, Somin; Han, Yong Seop; Kang, Tae Seen; Lee, Woongsup; Lee, Seongjin; Kim, Kyong Hoon; Choi, Hyunju; Lee, Seunghwan | Gyeongsang Natl Univ, Dept AI Convergence Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Gyeongsang Natl Univ Coll Med, Inst Hlth Sci, Dept Ophthalmol,Changwon Hosp, Jinju 52828, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 37224, South Korea; Deepnoid Inc, Seoul 08376, South Korea | Lee, Woongsup/AFK-2248-2022; Kim, Honghyok/LDF-5356-2024; Lee, Seongjin/AAI-2365-2020 | 56242902800; 57560243300; 57560243400; 57559364800; 57560905400; 55489221800; 57020662400; 24776183200; 24824950900; 15065463500; 57559364900; 57559365000 | jin.kim@gnu.ac.kr;chosd4603@gnu.ac.kr;ruru0213@gnu.ac.kr;namsohei1@gnu.ac.kr;csarah013044@gnu.ac.kr;medcabin@hanmail.net;tskang85@naver.com;wslee@gnu.ac.kr;insight@gnu.ac.kr;kyong.kim@knu.ac.kr;hjchoi@deepnoid.com;nasa10@deepnoid.com; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 1.05 | 2025-06-25 | 9 | 12 | visual acuity; fundus images; machine learning; ophthalmology; deep learning; SVM | deep learning; fundus images; machine learning; ophthalmology; SVM; visual acuity | English | 2022 | 2022-03 | 10.3390/app12063190 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | A Development of Visualization Technology through AR-Based Design Checklist Connection | Since the initial design review has the effect of minimizing the design changes needed in the later stages of an architectural project, a process of collaboration between architects, clients, and engineers in this design review is very important. Recently, design review using 3D models rendered in VR or AR, going beyond simple simulation, has been addressed in many studies. However, a synchronization function that provides immediate visualization of design changes is the focus, which has limitations in its ability to review factors required by law related to safety and design. The purpose of this study was, therefore, to develop AR-based design checklist linkage and visualization review technology that facilitates decision making by clients and architects during design review. For this purpose, a method for linking a design checklist in an AR environment using a game engine (Unity 3D) is proposed and various design review visualization functions are developed with consideration paid to the user interface. The efficiency of the design checklist linkage technology and visualization function developed in this study was verified in the pilot project. | Park, Hyejin; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 57226002455; 36835366900 | phj8598@knu.ac.kr;choo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 12 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.44 | 2025-06-25 | 3 | 5 | instructions; design review; decision making; augmented reality; design checklist; multi-dimension; visualization; mobile app | augmented reality; decision making; design checklist; design review; instructions; mobile app; multi-dimension; visualization | English | 2022 | 2022-06 | 10.3390/app12126126 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
