| ○ | ○ | Article | Maximization of the Power Production of an Offshore Wind Farm | Operating wind turbines together as a wind farm can be more advantageous and economical. As a result, onshore and offshore wind farms are being built at a rapid pace around the world. Wake effects, which have a negative impact on overall wind farm electricity generation, are one of the key concerns in wind farms. This work concentrates on the maximization of power output from wind farms by ameliorating the wake effect. This work introduces a dynamic wind farm controller that adjusts turbines' yaw angles or axial induction factors following the flow field conditions to maximize the overall power output of the wind farm. This research examines a real-life offshore wind farm in South Korea and the wind farm controller is evaluated in Wind Farm Simulator (WFSim), a control-oriented dynamic wind farm model environment built by Delft University of Technology. The main contribution of this work includes investigating the impact of wind farm control methods on the power production of a wind farm model that simulates a real-life wind farm. | Balakrishnan, Raj Kiran; Hur, Sung-ho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57656299100; 36455858700 | rajkiran89@knu.ac.kr;hur.s.h@ieee.org; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.87 | 2025-06-25 | 9 | 10 | wind farm control; wake redirection control; axial induction control; optimization | FIELD CAMPAIGN | axial induction control; optimization; wake redirection control; wind farm control | English | 2022 | 2022-04 | 10.3390/app12084013 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Method for Constructing a Facade Dataset through Deep Learning-Based Automatic Image Labeling | The construction industry has made great strides in recent decades by utilizing computer programs, including computer aided design programs. However, compared to the manufacturing sector, labor productivity is low because of the high proportion of knowledge-based tasks and simple repetitive tasks. Therefore, knowledge-based task efficiency should be improved through the visual recognition of information by computers. A computer requires a large amount of training data, such as the ImageNet project, to recognize visual information. This paper proposes facade datasets that are efficiently constructed by quickly collecting facade data through road-view images generated from web portals and automatically labeled using deep learning as part of the construction of image datasets for visual recognition construction by a computer. Therefore, we attempted to automatically label facade images to quickly generate large-scale facade datasets with much less effort than the existing research methods. Simultaneously, we constructed datasets for a part of Dongseong-ro, Daegu Metropolitan City, and analyzed their utility and reliability. It was confirmed that the computer could extract significant facade information from the road-view images by recognizing the visual information of the facade image. In addition, we verified the characteristics of the building construction image datasets. This study suggests the possibility of securing quantitative and qualitative facade design knowledge by extracting facade design information from facades anywhere in the world. Previous studies mainly collected facade images through camera photography to construct databases, but in this study, a significant part of the database construction process was shortened through automation. In the case of facade automatic image labeling studies, it is the facade-based automatic 3D modeling which has been primarily studied, but it is difficult to find a study to extract data for facade design research. | Gu, Hyeongmo; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 57209659182; 36835366900 | ghm3186@knu.ac.kr;choo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 15 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.52 | 2025-06-25 | 2 | 6 | facade; exterior building information; deep learning; image processing; image identification; image extraction | deep learning; exterior building information; façade; image extraction; image identification; image processing | English | 2022 | 2022-08 | 10.3390/app12157570 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Microstructure, Flexural Strength, and Fracture Toughness Comparison between CAD/CAM Milled and 3D-Printed Zirconia Ceramics | The present study comprehensively compared the microstructure, flexural strength, and fracture toughness of zirconia ceramics prepared via two different methods, subtractive milling (SM) and stereolithography (SLA). Disc- or rectangular-shaped zirconia specimens (Prettau (SM) and 3DMix Zirconia (SLA)) were prepared following each manufacturer's instructions and polished. The microstructures of the two different zirconia specimens were studied by scanning electron microscopy, X-ray diffractometry, energy-dispersive X-ray spectroscopy, and electron backscattered diffractometry. The flexural strength and fracture toughness based on the indentation fracture method were measured for the two different zirconia ceramics. A greater number of small pores and smaller grains were found in the SLA specimen than in the SM specimen. The crystal structure and microstructure analysis revealed that both ceramics had a similar phase composition to each other. No significant differences in flexural strength (p = 0.242) or fracture toughness (p = 0.101) were detected between the two ceramics. The mean flexural strength of the SLA-fabricated zirconia as well as the SM zirconia satisfied the class 5 criteria (>800 MPa) in the ISO 6872 standard. | Kim, Min-Su; Hong, Min-Ho; Min, Bong-Ki; Kim, Young-Kyung; Shin, Hyun-Jun; Kwon, Tae-Yub | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Catholic Univ Pusan, Coll Hlth Sci, Dept Dent Lab Sci, 57 Oryundae Ro, Busan 46252, South Korea; Yeungnam Univ, Ctr Res Facil, 280 Daehak Ro, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Yeungnam Univ Coll, Div Mech Engn Technol, 170 Hyeonchung Ro, Daegu 42415, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, 2177 Dalgubeol Daero, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Biomat Res & Dev, 2177 Dalgubeol Daero, Daegu 41940, South Korea | Kim, Chang/H-4759-2011 | 57902598800; 57192705343; 57211058922; 56017868900; 57903434800; 7202206084 | mhhong@cup.ac.kr;tykwon@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 1.49 | 2025-06-25 | 16 | 17 | zirconia ceramic; CAD; CAM milling; 3D-printing; microstructure; flexural strength; fracture toughness | MECHANICAL-PROPERTIES; ACCURACY; IMPLANTS | 3D-printing; CAD/CAM milling; flexural strength; fracture toughness; microstructure; zirconia ceramic | English | 2022 | 2022-09 | 10.3390/app12189088 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Mixer U-Net: An Improved Automatic Road Extraction from UAV Imagery | Automatic road extraction from unmanned aerial vehicle (UAV) imagery has been one of the major research topics in the area of remote sensing analysis due to its importance in a wide range of applications such as urban planning, road monitoring, intelligent transportation systems, and automatic road navigation. Thanks to the recent advances in Deep Learning (DL), the tedious manual segmentation of roads can be automated. However, the majority of these models are computationally heavy and, thus, are not suitable for UAV remote-sensing tasks with limited resources. To alleviate this bottleneck, we propose two lightweight models based on depthwise separable convolutions and ConvMixer inception block. Both models take the advantage of computational efficiency of depthwise separable convolutions and multi-scale processing of inception module and combine them in an encoder-decoder architecture of U-Net. Specifically, we substitute standard convolution layers used in U-Net for ConvMixer layers. Furthermore, in order to learn images on different scales, we apply ConvMixer layer into Inception module. Finally, we incorporate pathway networks along the skip connections to minimize the semantic gap between encoder and decoder. In order to validate the performance and effectiveness of the models, we adopt Massachusetts roads dataset. One incarnation of our models is able to beat the U-Net's performance with 10x fewer parameters, and DeepLabV3's performance with 12x fewer parameters in terms of mean intersection over union (mIoU) metric. For further validation, we have compared our models against four baselines in total and used additional metrics such as precision (P), recall (R), and F1 score. | Sultonov, Furkat; Park, Jun-Hyun; Yun, Sangseok; Lim, Dong-Woo; Kang, Jae-Mo | Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Informat & Commun Engn, Busan 48513, South Korea; Elect & Telecommun Res Inst ETRI, Radio & Satellite Res Div, Daejeon 34129, South Korea | SULTONOV, FURKAT/NFS-3340-2025; Park, Jun-Hyun/CAG-5910-2022 | 57455045300; 57455816200; 56115729600; 55694295300; 56024930400 | furkatsultonov@knu.ac.kr;wnsgus126@knu.ac.kr;ssyun@pknu.ac.kr;window0508@etri.re.kr;jmkang@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 1.92 | 2025-06-25 | 22 | 24 | mixer U-Net; semantic segmentation; road extraction; unmanned aerial vehicles | SEGMENTATION; NETWORKS | Mixer U-Net; Road extraction; Semantic segmentation; Unmanned aerial vehicles | English | 2022 | 2022-02 | 10.3390/app12041953 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Noise Characteristics Analysis of Medical Electric Leg Compression Machine Using Multibody Dynamic Simulation | Conventional medical equipment used for treating patients with ischemic heart disease relies on pneumatic compression to achieve intense and instantaneous compression of the legs. Because the pneumatic operation of a compressor inevitably produces noise, the treatment is given to a patient in a separate room to avoid causing discomfort to other patients. This need for a dedicated treatment room could be another source of increased medical costs. In this study, a new electrical motor-driven system was developed to address the noise problem of existing pneumatic compression devices. Additionally, the new system features a reduced footprint and weight, and can be carried by medical staff. To develop a low-noise leg compression machine, the noise level at the surface of the structure was estimated using multibody dynamics simulation. Based on the initial design of the electric leg compression machine, parameters including assembly tolerance, component material, and shape of the structure were adjusted to prepare variations of the initial design, and their noise characteristics were analyzed. It was found that by applying the design variables, the noise levels were reduced by 7.2-11.7% compared with the initial design. The most significant reduction in noise levels was 11.7% and was achieved by reinforcing the section surrounding the gearbox enclosing a noise source. | Kang, Sungwook; Kim, Hyunsoo; Kim, Jaewoong; Hwang, Jong-Moon; Lee, Wonhee; Kim, Jungtae; Ryu, Hyunsu | Korea Inst Ind Technol, Precis Mech Proc & Control R&D Grp, Jinju 52845, South Korea; Korea Inst Ind Technol, Smart Mobil Mat & Components R&D Grp, Gwangju 61012, South Korea; Kyungpook Natl Univ, Sch Med, Dept Rehabil Med, Daegu 41566, South Korea; OsteoSys Co Ltd, R&D Ctr, Seoul 08390, South Korea; Changwon Natl Univ, Sch Ind Engn & Naval Architecture, Chang Won 51140, South Korea | KANG, SUNGWOOK/AAF-6339-2021; Lee, Wonhee/IVV-5009-2023 | 55611458600; 59866441700; 7601367283; 56367634000; 57641030900; 57638490500; 36952669600 | swkang@kitech.re.kr;hyun0702@kitech.re.kr;kjw0607@kitech.re.kr;hti82@knu.ac.kr;wonhee@osteosys.com;jaytee@osteosys.com;hsryu@changwon.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.09 | 2025-06-25 | 1 | 1 | multibody dynamics; noise characteristics; gear box; medical device | ENHANCED EXTERNAL COUNTERPULSATION; HOSPITAL NOISE; POLYACETAL | gear box; medical device; multibody dynamics; noise characteristics | English | 2022 | 2022-04 | 10.3390/app12083977 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | On the Security of a Lightweight and Secure Access Authentication Scheme for Both UE and mMTC Devices in 5G Networks | The Internet of Things (IoT) and 5G networks play important roles in the latest systems for managing and monitoring various types of data. These 5G based IoT environments collect various data in real-time using micro-sensors as IoT things devices and sends the collected data to a server for further processing. In this scenario, a secure authentication and key agreement scheme is needed to ensure privacy when exchanging data between IoT nodes and the server. Recently, Cao et al. in "LSAA: A lightweight and secure access authentication scheme for both UE and mMTC devices in 5G networks" presented a new authentication scheme to protect user privacy. They contend that their scheme not only prevents various protocol attacks, but also achieves mutual authentication, session key security, unlinkability, and perfect forward/backward secrecy. This paper demonstrates critical security weaknesses of their scheme using informal and formal (mathemati) analysis: it does not prevent a single point of failure and impersonation attacks. Further, their proposed scheme does not achieve mutual authentication and correctness of security assumptions, and we perform simulation analysis using a formal verification tool to its security flaws. To ensure attack resilience, we put forward some solutions that can assist constructing more secure and efficient access authentication scheme for 5G networks. | Park, Kisung; Park, Youngho | Elect & Telecommun Res Inst, Blockchain Res Ctr, Daejeon 34129, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | ; Park, Kisung/KIG-3849-2024 | 57194833768; 56962990300 | ks.park@etri.re.kr;parkyh@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.17 | 2025-06-25 | 1 | 2 | 5G; authentication; Internet of Things (IoT); key agreement; security weaknesses | 3-FACTOR USER AUTHENTICATION; ELLIPTIC CURVE CRYPTOSYSTEM; PROTOCOL | 5G; authentication; Internet of Things (IoT); key agreement; security weaknesses | English | 2022 | 2022-05 | 10.3390/app12094265 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Optical Modalities for Research, Diagnosis, and Treatment of Stroke and the Consequent Brain Injuries | Stroke is the second most common cause of death and third most common cause of disability worldwide. Therefore, it is an important disease from a medical standpoint. For this reason, various studies have developed diagnostic and therapeutic techniques for stroke. Among them, developments and applications of optical modalities are being extensively studied. In this article, we explored three important optical modalities for research, diagnostic, and therapeutics for stroke and the brain injuries related to it: (1) photochemical thrombosis to investigate stroke animal models; (2) optical imaging techniques for in vivo preclinical studies on stroke; and (3) optical neurostimulation based therapy for stroke. We believe that an exploration and an analysis of previous studies will help us proceed from research to clinical applications of optical modalities for research, diagnosis, and treatment of stroke. | Oh, Sung Suk; Kim, Yoonhee; Lee, Yoon Bum; Bae, Seung Kuk; Kim, Jun Sik; An, Sang-hyun; Choi, Jong-ryul | Daegu Gyeongbuk Med Innovat Fdn K Med Hub, Med Device Dev Ctr, Daegu 41061, South Korea; Kyungpook Natl Univ, Sch Med, Dept Med Sci, Daegu 41944, South Korea; Daegu Gyeongbuk Med Innovat Fdn K Med Hub, Preclin Res Ctr, Daegu 41061, South Korea; Osong Med Innovat Fdn, Lab Anim Ctr, Cheonju 28160, South Korea | ; Kim, Jun/AAA-8565-2019 | 57193393986; 57222362589; 57222355818; 57210116959; 57207438954; 57102583100; 24773058200 | korea5016@kbiohealth.kr;jongryul32@kmedihub.re.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.35 | 2025-06-25 | 4 | 4 | biomedical optics; optical imaging; phototherapy; photochemical thrombosis; stroke | NEAR-INFRARED SPECTROSCOPY; CEREBRAL-ARTERY OCCLUSION; ACUTE ISCHEMIC-STROKE; COHERENCE TOMOGRAPHY; LASER THERAPY; TRANSCRANIAL PHOTOBIOMODULATION; PHOTOTHROMBOTIC STROKE; HEMODYNAMIC-RESPONSES; FUNCTIONAL RECOVERY; LIGHT | Biomedical optics; Optical imaging; Photochemical thrombosis; Phototherapy; Stroke | English | 2022 | 2022-02 | 10.3390/app12041891 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Optimal Spatial Coherence of a Light-Emitting Diode in a Digital Holographic Display | The coherence of a light source is a vital aspect regarding the image quality of holographic contents. Generally, the coherence of the light source is the reason for speckle noise in a holographic display, which degrades the image quality. To reduce the speckle noise, partially coherent light sources such as light-emitting diodes (LED) have been studied. However, if the coherence of the light source is too low, the reconstructed image will blur. Therefore, using a spatial filter to improve the spatial coherence of LEDs has been proposed. In this study, we analyze the effect of the spatial and temporal coherence of the LED light source in a digital holographic display, and the optimal spatial coherence is determined. For this purpose, we devised an optical structure to control the spatial coherence in a holographic display system using a digital micro-mirror device (DMD). Here, the DMD functions as a dynamic spatial filter. By evaluating the change in the holographic image quality according to the spatial filter size, we obtained an optimal spatial filter size of 270 mu m in our system. The proposed method is expected to be useful for selecting the optimal coherence of the light source for holographic displays. | Lim, Sungjin; Jeon, Hosung; Ahn, Sunggyun; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu, South Korea | 56706721300; 56663784700; 57208884987; 10142501600 | dlatjdwls0326@knu.ac.kr;jhs0485@knu.ac.kr;geni4160@knu.ac.kr;jhahn@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 9 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.7 | 2025-06-25 | 8 | 8 | digital holographic display; coherence system; digital micro-mirror device; light-emitting diode | SPECKLE NOISE | coherence system; digital holographic display; digital micro-mirror device; light-emitting diode | English | 2022 | 2022-05 | 10.3390/app12094176 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Optimization of the Power Conversion Efficiency of CsPbIxBr3-x-Based Perovskite Photovoltaic Solar Cells Using ZnO and NiOx as an Inorganic Charge Transport Layer | In this study, we analyzed the maximum power conversion efficiency (PCE) of a photovoltaic cell with an ITO/ZnO/CsPbIxBr3-x/NiOx/Au structure, using ZnO and NiOx as the inorganic charge transport layers and CsPbIxBr3-x as an absorption layer. We optimized the thickness of each layer and investigated the effects of the defect density and interface defect density. To achieve the highest PCE, the optimal thicknesses were 300 nm for the electron transport layer (ZnO), 60 nm for the hole transport layer (NiOx), and 1000 nm for the absorption layer. The absorber defect density was maintained at approximately 10(15) cm(-3), and the interface defect density was approximately 10(11) cm(-3). The highest PCE obtained through optimization of each of these factors was 23.07%. These results are expected to contribute to the performance optimization of perovskite solar cells that use inorganic charge carrier transport layers. | Son, Hyojung; Jeong, Byoung-Seong | Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea | 57902836700; 35895071700 | gatorever@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.87 | 2025-06-25 | 9 | 10 | perovskite photovoltaic solar cell; CsPbIxBr3-x; ZnO; NiOx; power conversion efficiency | PERFORMANCE; SIMULATION; THICKNESS; OXIDE | CsPbI<sub>x</sub>Br<sub>3−x</sub>; NiO<sub>x</sub>; perovskite photovoltaic solar cell; power conversion efficiency; ZnO | English | 2022 | 2022-09 | 10.3390/app12188987 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Orlistat, a competitive lipase inhibitor used as an antiobesity remedy, enhances inflammatory reactions in the intestine | Alterations in secondary gut metabolites derived from the microbial fermentation of food in the gut have significant effects on various aspects of host physiology. Our recent studies on obese mice treated with Orlistat, an antiobesity treatment, revealed a significantly altered gut microbial profile marked by an over-abundance of Proteobacteria and alterations in secondary gut metabolites. In this study, we determined effect of fecal metabolites from high-fat diet fed mice treated with Orlistat (HFDOrl) on colonic epithelial cells in relation to inflammation, barrier function, mitochondrial activity, reactive oxygen species (ROS) levels, and oxidative stress. Quantitative PCR was used to measure intestinal mRNA expression of oxidative stress, inflammation, apoptosis, and gut barrier function genes in mice on a high fat diet with and without Orlistat treatment versus those fed a low-fat diet (HFDOrl, HFD, Normal diet-fed [ND] respectively). Alterations to antioxidant function in HCT-116-ARE-luciferase stable cell line and mitochondrial function in Caco-2 cells was analyzed under oxidative stress with exposure to aqueous fecal extracts from HFDOrl, HFD, and ND groups. The results of this study indicate that a significant increase in anti-oxidative response was observed based on the luciferase activity of HCT-116-ARE-luciferase stable cells. Increased maximal respiration and mitochondrial ROS under oxidative stress was also detected in confluent Caco-2 cells resulting from exposure to fecal extracts from the HFDOrl group compared with the HFD group and pure Orlistat. Furthermore, mice from the HFDOrl group exhibited a significant increase in colonic epithelial expression of oxidative markers (Nrf-2 and SOD-2), inflammation-related markers (IL-6 and TNF-alpha), and gut barrier function markers (Muc-2 and Occludin). Taken together, the results suggest that Orlistat treatment in the HFD group causes changes in secondary gut metabolites which affect the colonic redox state and may eventually lead to the development of inflammatory, oxidative, and mitochondrial dysfunction at the cellular level. | Katimbwa, Dorsilla Anono; Oh, Jisun; Jang, Chan Ho; Lim, Jinkyu | Kyungpook Natl Univ, Dept Food Biomat, 80 Daehak Ro, Daegu, South Korea; Daegu Gyeongbuk Med Innovat Fuundat K Medihub, New Drug Dev Ctr, 80 Cheombok ro, Daegu 41061, South Korea; Kyungpook Natl Univ, Inst Agr Sci & Technol, 80 Daehak Ro, Daegu, South Korea | 57221787136; 56311554100; 24477187500; 7403454071 | jkylim@knu.ac.kr; | APPLIED BIOLOGICAL CHEMISTRY | APPL BIOL CHEM | 2468-0834 | 2468-0842 | 65 | 1 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2022 | 3.2 | 46.1 | 0.81 | 2025-06-25 | 11 | 11 | Oxidative stress; Mitochondrial dysfunction; Inflammation; Orlistat | GUT MICROBIOTA; WEIGHT-LOSS; HIGH-FAT; INCREASES; OBESITY; HUMANS | Inflammation; Mitochondrial dysfunction; Orlistat; Oxidative stress | Biomolecules; Cell culture; Cell death; Mammals; Metabolites; Mitochondria; Pathology; Polymerase chain reaction; Antiobesity; Barriers functions; Caco-2 cells; Gut barrier; High-fat-diet; Inflammation; Inflammatory reaction; Mitochondrial dysfunction; Orlistat; Reactive oxygen species; Oxidative stress | English | 2022 | 2022-12 | 10.1186/s13765-022-00712-y | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Parametric Method and Building Information Modeling-Based Cost Estimation Model for Construction Cost Prediction in Architectural Planning | Economic feasibility and cost analysis in the preliminary planning stage of early-phase construction projects have a significant impact on project management and implementation. However, while estimating the construction cost per unit area, the existing approaches do not account for factors other than the area-related information, causing estimation error. Therefore, a construction cost estimation model that can be utilized in the early phase of a construction project is developed in this study based on BIM in the architectural planning stage. Moreover, goodness of fit and accuracy of the model were verified through a validation method considering the BIM design process. The proposed model showed higher accuracy than the conventional models in terms of the floor area. Furthermore, it was possible to confirm the model performance based on the cost estimation accuracy range presented by the AACE. In addition, the developed model can generate estimation results corresponding to Class 1-3, a subsequent construction project stage. The findings of this study emphasize the importance of jointly considering the processes related to construction cost estimation and indicate that parameters other than the floor area need to be considered for construction cost estimation in the early phase of a construction project. | Yang, Seung-Won; Moon, Seong-Wan; Jang, Hangyeol; Choo, Seungyeon; Kim, Sung-Ah | Sungkyunkwan Univ, Dept Global Smart City, 2066 Seobu Ro, Suwon 16419, South Korea; Sungkyunkwan Univ, Dept Architecture, 2066 Seobu Ro, Suwon 16419, South Korea; Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea | ; Choo, Seungyeon/JFB-0390-2023 | 57931178300; 57930885700; 57931323500; 36835366900; 25927159900 | sakim@skku.edu; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 1.22 | 2025-06-25 | 10 | 14 | BIM (building information modeling); construction cost estimation; economic feasibility; project management | BIM (building information modeling); construction cost estimation; economic feasibility; project management | English | 2022 | 2022-10 | 10.3390/app12199553 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Phosphine Fumigation Followed by Cold Treatment to Control Peach Fruit Moth, Carposina sasakii, Larvae on "Fuji" Apples Intended for Export | Featured Application A new application of phosphine fumigation with cold treatment to control peach fruit moth larvae Carposina sasakii. The fumigation of apples using methyl bromide (MeBr) can cause severe deterioration in fruit quality. Moreover, maintaining the quality of apples during postharvest storage and eradicating pests, especially those involved in quarantine issues, are important for facilitating the export of apples, including the "Fuji" apple (Malus pumila var. "Fuji") in South Korea. In the present study, phosphine (PH3) fumigation as an alternative to MeBr was found to be more effective for the control of peach fruit moth larvae (Carposina sasakii), which had naturally infested Fuji apples, at a high temperature (25 degrees C) rather than at a low temperature (5 degrees C). To achieve the industry requirement of better-quality perishable commodities and meet quarantine guidelines for export, PH3 fumigation at the low temperature (5 degrees C) was followed by cold treatments at 3 +/- 2 degrees C for 2 and 4 weeks, which led to higher efficacy than was achieved using PH3 at 5 degrees C alone. Given that chemical treatments, such as treatment with 1-methylcyclopropene, can inhibit ethylene synthesis, low-temperature PH3 fumigation for 72 h followed by 4 weeks of cold treatment could also extend the shelf life of apples and resolve known quarantine issues when used as an alternative to MeBr treatment. | Kim, Bong-Su; Hong, Ki-Jeong; Kwon, Tae-Hyung; Lee, Kyeong-Yeoll; Lee, Byung-Ho; Lee, Sung-Eun | Anim & Plant Quarantine Agcy APQA, Plant Quarantine Technol Ctr, Gimcheon 39660, South Korea; Sunchon Natl Univ, Dept Plant Med, 255 Jungang Ro, Sunchon 57922, South Korea; Kyungpook Natl Univ, Inst Evaluat Safety & Qual Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea | ; Kim, Bong-Soo/L-4779-2013 | 57190759576; 33067733500; 57215832186; 57217153096; 57202841615; 55890041600 | bskim79@korea.kr;curcul@sunchon.ac.kr;xoxogudgud@naver.com;leeky@knu.ac.kr;byungholee@knu.ac.kr;selpest@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 15 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.26 | 2025-06-25 | 3 | 3 | phosphine fumigation; cold treatment; peach fruit moth; Fuji apple export | TEMPERATURE; DISINFESTATION; TOMATO; PEPPER | cold treatment; Fuji apple export; peach fruit moth; phosphine fumigation | English | 2022 | 2022-08 | 10.3390/app12157514 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Prediction of Minimum Night Flow for Enhancing Leakage Detection Capabilities in Water Distribution Networks | In South Korea, a water supply enhancement project is being carried out to preemptively respond to drought and water loss by reducing pipeline leakages and supplying stable tap water through the maintenance of an aging water supply network. In order to reduce water leakage, a District Metered Area (DMA) was established to monitor and predict the minimum night flow based on flow data collected from IoT sensors. In this study, a model based on Multi-Layer Perceptron (MLP) and Long Short-Term Memory (LSTM) was constructed to predict the MNF (minimum night flow) of County Y. The prediction of MNF results was compared with the MLP networks and the LSTM model. The outcome showed that the LSTM-MNF model proposed in this study performed better than the MLP-MNF model. Therefore, the research methods of this study can contribute to technical support for leakage reductions by preemptively responding to the expected increase in leakage through the prediction of the minimum flow at night. | Lee, Sang Soo; Lee, Ho-Hyun; Lee, Yun-Jung | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Korea Water Resources Corp, K Water Res Inst, Daejeon 34045, South Korea | 57776667400; 55552563000; 55716144300 | sangsoo@kwater.or.kr;lhh@kwater.or.kr;yjlee@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 13 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.7 | 2025-06-25 | 7 | 9 | LSTM; water leakage; minimum night flow; waterworks; water network | LSTM; minimum night flow; water leakage; water network; waterworks | English | 2022 | 2022-07 | 10.3390/app12136467 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Repetitive Bacterial Disinfection of Respirators by Polydopamine Coating | To solve the current and future mask shortage problems, developing methods of disinfecting respirators is essential, where none of the existing methods have been successfully utilized until recently. Herein, we introduce a novel method of conferring antibacterial activity to the main filtering material (i.e., polypropylene (PP)) of a respirator through sequential polydopamine (PDA) coatings. Two-step dip-coating in dopamine solution, which corresponds to one complete cycle, produces stable PDA films at the interface of the filtering material, which subsequently locally generates H2O2 that can be further transformed into hydroxyl radicals to inactivate pathogens. Specifically, the primary dip-coating creates a scaffold PDA film that acts as a mechanical support, and anchoring dopamine, which substantially produces H2O2, is immobilized to the scaffold PDA during the subsequent secondary dip-coating process. The antibacterial activity was confirmed by bacterial tests using Escherichia coli. In short, the number of colonies after incubation of the polypropylene filter with and without the PDA coating in the bacterial solution was compared. The number of bacteria in the PDA-coated sample (0.54 x 10(9) CFU/mL center dot cm(2)) was significantly reduced compared to that in the original PP sample (0.81 x 10(9) CFU/mL center dot cm(2)), demonstrating a positive relationship with the H2O2 production. Moreover, this antibacterial ability can be maintained by simply utilizing additional PDA coatings, suggesting that the respirators can be recycled. Finally, the in vitro cytotoxicity was confirmed by the CCK-8 assay, which demonstrated that the PDA-coated PP filter is biocompatible. We believe that the newly proposed method for disinfection of respirators may substitute conventional methods and can be used to alleviate the mask shortage problem. | Jeong, Yuri; Lee, Kyueui | Kyungpook Natl Univ, Dept Appl Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | Lee, Kyueui/ACR-8902-2022; Lee, Kyueui/P-8152-2018 | 58564255500; 56404800600 | kyueui@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 17 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 0.17 | 2025-06-25 | 2 | 2 | polydopamine; antibacterial materials; mask shortage; biomimetics; pandemics | SURFACE; DECONTAMINATION; MASKS; N95; ADHESION | antibacterial materials; biomimetics; mask shortage; pandemics; polydopamine | English | 2022 | 2022-09 | 10.3390/app12178710 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Review of Recent Automated Pothole-Detection Methods | Potholes, a kind of road defect, can damage vehicles and negatively affect drivers' safe driving, and in severe cases can lead to traffic accidents. Efficient and preventive management of potholes in a complex road environment plays an important role in securing driver safety. It is also expected to contribute to the prevention of traffic accidents and the smooth flow of traffic. In the past, pothole detection was mainly performed via visual inspection by human experts. Recently, automated pothole-detection methods apply various technologies that converge basic technologies such as sensors and signal processing. The automated pothole-detection methods can be classified into three types according to the technology used in the pothole-recognition process: a vision-based method, a vibration-based method, and a 3D reconstruction-based method. In this paper, three methods are compared, and the strengths and weaknesses of each method are summarized. The detection process and technology proposed in the latest research related to automated pothole detection are described for each method. The development plans of future technology that is connected with those studies are also presented in this paper. | Kim, Young-Mok; Kim, Young-Gil; Son, Seung-Yong; Lim, Soo-Yeon; Choi, Bong-Yeol; Choi, Doo-Hyun | Def Agcy Technol & Qual, C4ISR Syst Dev Qual Team, Daejeon 34327, South Korea; Kyungpook Natl Univ, Grad Sch Ind, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Fine Arts, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57463096300; 57732321400; 57462938800; 7404081100; 8203769300; 7401642881 | ymokkim@dtaq.re.kr;ykkim0033@dtaq.re.kr;sonseungyong@knu.ac.kr;sylim@knu.ac.kr;bychoi@ee.knu.ac.kr;dhc@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 12 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 2.7 | 46.1 | 2.63 | 2025-06-25 | 47 | 82 | pothole; automated detection; vision; vibration; 3D reconstruction; image processing; deep learning | 3D reconstruction; automated detection; deep learning; image processing; pothole; vibration; vision | English | 2022 | 2022-06 | 10.3390/app12115320 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
