| ○ | ○ | Article | Fluorescence behaviors of perylene-dispersed super engineering plastic films | We attempted to manufacture films in which fluorescent dye is dispersed using engineering plastic as a matrix which has high heat and chemical resistance as well as excellent mechanical performance. In this study, films containing highly dispersed perylene in colorless and transparent aromatic polyamide (PA) and polyimide (PI) were manufactured. The perylene-dispersed PA film emitted strong blue light with a maximum fluorescence at 457 nm. On the other hand, the perylene-dispersed PI film showed significant fluorescence quenching with its maximum fluorescence wavelength significantly red -shifted to 546 nm. The perylene-dispersed PI film treated with ethylene diamine at 80 degrees C showed strong blue fluorescence, and when the film was further heated at 200 degrees C, the fluorescence was quenched. These films are expected to be applied as back light unit or color conversion layer for OLED and Micro LED due to their excellent physical properties. | Kim, Heesang; Ham, Gayoung; Cha, Hyojung; Kwak, Giseop | Kyungpook Natl Univ, Dept Polymer Sci & Engn, 1370 Sankyuk Dong, Daegu 702701, South Korea; Kyungpook Natl Univ, Dept Energy Convergence & Climate Change, Daegu, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, 1370 Sankyuk Dong, Daegu 702701, South Korea | , Giseop/M-8370-2018 | 57226091356; 58506766600; 35885242200; 17137322300 | gkwak@knu.ac.kr; | POLYMER | POLYMER | 0032-3861 | 1873-2291 | 303 | SCIE | POLYMER SCIENCE | 2024 | 4.5 | 28.2 | 0 | 2025-05-07 | 0 | 0 | Perylene; Fluorescence; Polyamide; Polyimide; Ethylene diamine | OPTICAL-DATA STORAGE; POLYMER; DYES; AGGREGATION; SPECTRA; COMPLEX; PYRENE | Ethylene diamine; Fluorescence; Perylene; Polyamide; Polyimide | Amines; Ethylene; Fluorescence quenching; Heat resistance; Polycyclic aromatic hydrocarbons; Red Shift; Aromatic polyamides; Engineering plastics; Ethylene diamine; Fluorescence behaviors; Fluorescent dyes; matrix; Mechanical performance; Perylenes; Plastic-film; Polyimide film; Polyimides | English | 2024 | 2024-05-23 | 10.1016/j.polymer.2024.127147 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Thermal Infrared Orthophoto Geometry Correction Using RGB Orthophoto for Unmanned Aerial Vehicle | The geometric correction of thermal infrared (TIR) orthophotos generated by unmanned aerial vehicles (UAVs) presents significant challenges due to low resolution and the difficulty of identifying ground control points (GCPs). This study addresses the limitations of real-time kinematic (RTK) UAV data acquisition, such as network instability and the inability to detect GCPs in TIR images, by proposing a method that utilizes RGB orthophotos as a reference for geometric correction. The accelerated-KAZE (AKAZE) method was applied to extract feature points between RGB and TIR orthophotos, integrating binary descriptors and absolute coordinate-based matching techniques. Geometric correction results demonstrated a significant improvement in regions with stable and changing environmental conditions. Invariant regions exhibited an accuracy of 0.7 similar to 2 px (0.01 similar to 0.04), while areas with temporal and spatial changes saw corrections within 5 similar to 7 px (0.10 similar to 0.14 m). This method reduces reliance on GCP measurements and provides an effective supplementary technique for cases where GCP detection is limited or unavailable. Additionally, this approach enhances time and economic efficiency, offering a reliable alternative for precise orthophoto generation across various sensor data. | Lee, Kirim; Lee, Wonhee | Kyungpook Natl Univ, Res Inst Artificial Intelligent Diag Technol Multi, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Locat Based Informat Syst, Sangju 37224, South Korea | 57193932338; 57190774365 | geolee@knu.ac.kr;wlee33@knu.ac.kr; | AEROSPACE | AEROSPACE-BASEL | 2226-4310 | 11 | 10 | SCIE | ENGINEERING, AEROSPACE | 2024 | 2.2 | 28.2 | 0.5 | 2025-05-07 | 1 | 1 | UAV; TIR; RGB; GCP; geometric correction; AKAZE | MODELS | AKAZE; GCP; geometric correction; RGB; TIR; UAV | English | 2024 | 2024-10 | 10.3390/aerospace11100817 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | An Investigation of Garlic's Physical Properties Prior to Collection for the Development of a Garlic Collector | In this study, the physical properties of garlic just before collection were investigated, and garlic-collecting conditions are presented as basic data of design factors that can be utilized during the development of garlic collectors. The physical properties were subdivided into geometrical properties and mechanical properties, and the ecotype of garlic was divided into CSG (cold-season garlic) and WSG (warm-season garlic). Geometrical properties were compared between CSG and WSG by measuring the average weight, length, width, number of kernels, volume, and density of each cultivar, and WSG showed higher geometrical properties in all geometrical properties. In addition, there was garlic on the incomplete side of WSG, and shape non-uniformity was higher than that of CSG. There was no significant difference in the average Poisson's ratio of mechanical properties. In the case of the modulus of elasticity, Namdo cultivars showed the lowest value at 15.52 MPa. The average allowable compressive stress measured using Hooke's law was the lowest in the Uiseong cultivar (204.33 kPa) and the highest in the Danyang cultivar (376.42 kPa). The static friction coefficients among the four different materials by cultivar exhibited a commonality of being highest in aluminum and generally lowest in plastic. It is expected that the design of the garlic collector will be carried out in consideration of garlic when developing it using up-to-date physical properties of garlic just before collection. | Park, Hyung-Gyu; Kang, Seok-Ho; Kim, Yong-Gik; Son, Jin-Ho; Kim, Yeong-Su; Woo, Seung-Min; Ha, Yu-Shin | Kyungpook Natl Univ, Dept Bioind Machinery Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Upland Field Machinery Res Ctr, Daegu 41566, South Korea | 57279183700; 57221791368; 58419351400; 57879932100; 57210594021; 57192074884; 57192072314 | pyd7169@naver.com;deshshk@naver.com;dydwlr9988@knu.ac.kr;thsghqkd@knu.ac.kr;mvio9256@naver.com;kooger7571@naver.com;yushin72@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 1 | physical properties; just before collection; geometrical properties; mechanical properties; cold-season garlic; garlic collector; warm-season garlic | cold-season garlic; garlic collector; geometrical properties; just before collection; mechanical properties; physical properties; warm-season garlic | English | 2024 | 2024-02 | 10.3390/app14041644 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Biocontrol of Aflatoxin-Producing Aspergillus flavus ATCC 22546 by a Non-Aflatoxigenic Aspergillus flavus ATCC 9643 | Featured Application Biocontrol of aflatoxin-producing Aspergillus flavus ATCC 22546 and the inhibitory effect on aflatoxin biosynthesis of a non-aflatoxigenic Aspergillus flavus ATCC 9643. Abstract The biological control of Aspergillus flavus and A. parasiticus by non-aflatoxigenic strains has been introduced in cotton- and peanut-cultivating fields and proven successful at reducing aflatoxin (AFB) contamination of crops and agricultural soils. In this study, a non-aflatoxigenic strain, A. flavus ATCC 9643 (ATCC 9643), was evaluated for its ability to competitively inhibit the growth of an aflatoxigenic strain, A. flavus ATCC 22546 (ATCC 22546), and mitigate AFB production in ATCC 22546 during competitive growth. To comparatively analyze the suppressive effect of ATCC 9643 on ATCC 22546, a non-aflatoxigenic strain (A. flavus ATCC 96045, known as AF36) was used as a positive control in some experiments. The two non-aflatoxigenic strains did not produce AFB1 or AFB2 owing to the absence of several AFB biosynthesis-related genes, especially aflK and aflL, which encode versicolorin B synthase and desaturase, respectively. To create a competitive growth environment, ATCC 9643 and ATCC 22546 were co-inoculated into a solid agar medium, and they grew at similar rates when added at a 1:1 ratio. Increasing the inoculum rate of ATCC 9643 (1:1, 1:3, 1:5) dramatically inhibited ATCC 22546 growth, and AFB production was effectively decreased by about 84%, 95%, and 97% by treatment with ATCC 9643. On rice, ATCC 22546 attenuated ATCC 9643 growth only when the rice was submerged in distilled water, whereas agar addition enhanced it. Taken together, ATCC 9643 is a promising candidate biological agent for suppressing aflatoxigenic A. flavus strain growth and alleviating AFB contamination. Further studies on AFB reduction in crop fields, including cotton-cultivation and maize-cultivation fields, are warranted. | Jung, Kwang-Soo; Kim, Hyeong-Mi; Lee, Jieun; Ganbat, Dariimaa; Lee, Sung-Eun | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea | Lee, Jieun/LXB-0158-2024 | 59234509300; 57202103829; 59448694000; 57225264879; 55890041600 | splendor47@knu.ac.kr;guddkwhdk@knu.ac.kr;jibog123@knu.ac.kr;dariim91@knu.ac.kr;selpest@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 14 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.73 | 2025-05-07 | 2 | 2 | Aspergillus flavus; aflatoxins; non-aflatoxigenic strain; biocontrol | BIOLOGICAL-CONTROL; WILD-TYPE; STRAINS; CONTAMINATION; BIOSYNTHESIS; FORMULATIONS; PISTACHIO; AF36; NUTS | aflatoxins; Aspergillus flavus; biocontrol; non-aflatoxigenic strain | Algae; Aspergillus; Biochemistry; Biocontrol; Biosynthesis; Cotton; Crops; Cultivation; Polysaccharides; Strain; Aflatoxigenic strains; Aflatoxin biosynthesis; Agricultural soils; Aspergillus flavus; Biological controls; Competitive growth; Crop soils; Inhibitory effect; Non-aflatoxigenic strain; Parasiticus; Aflatoxins | English | 2024 | 2024-07 | 10.3390/app14146142 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bone Integration of Femtosecond Laser-Treated Dental Implants with Nanostructured Surfaces: A Controlled Animal Study | Background: The purpose of this study is to compare bone union and soft-tissue healing in titanium implants with sandblasted, large-grit, acid-etched surfaces (SLA group) and femtosecond laser-treated surfaces (FEMTO group) in a rabbit model. Methods: Implants were inserted into rabbit tibiae, and implant stability, soft-tissue healing, and microscopic analyses (micro-CT and biopsy) were conducted. All animals maintained normal weight and health post-surgery. Results: Hemostasis was achieved at the laser incision site on the surgery day, but healing was slower compared to conventional methods. Micro-CT showed no significant differences in new bone formation or inflammatory tissue infiltration between groups. Tissue biopsy revealed slightly higher bone-implant contact in the FEMTO group compared to the SLA group, though not statistically significant. Conclusion: These findings suggest that femtosecond laser surface treatment may provide bone union comparable to or better than SLA treatment, though laser-assisted soft-tissue incisions heal more slowly. | Do, Woo-Seok; Son, Keun-Ba-Da; Son, Young-Tak; Kim, Yong-Gun; Hwang, Sung-Min; Hwang, Jun-Ho; Lee, Jong-Hoon; Kim, Hyun-Deok; Lee, Kyu-Bok; Lee, Jae-Mok | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu 41940, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Adv Convergence Technol, Daegu 41061, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | ; SON, Keunbada/AAG-8089-2019; Son, Keunbada/AAG-8089-2019; Kim, Yong Joon/IQS-7291-2023 | 59072915500; 57202916520; 57219111205; 55622694400; 57870525500; 57204783286; 57204786073; 55663858300; 15925571200; 17346330000 | jd06hanmail@naver.com;oceanson@knu.ac.kr;dudxkr741@naver.com;periokyg@knu.ac.kr;lhwangl89@naver.com;hjh@iact.or.kr;laser@knu.ac.kr;hdkim@knu.ac.kr;kblee@knu.ac.kr;leejm@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 23 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | dental implants; dental lasers; femtosecond laser; osseointegration; titanium surface engineering | TITANIUM IMPLANT; DIODE-LASER; FIBROUS HYPERPLASIA; SCALPEL SURGERY; IN-VIVO; OSSEOINTEGRATION; PULSES | dental implants; dental lasers; femtosecond laser; osseointegration; titanium surface engineering | Biopsy; Dental prostheses; Laser surgery; Metal implants; Tissue regeneration; Bone union; Dental lasers; Femtoseconds; Laser treated; Micro CT; Osseointegration; Soft tissue healing; Surface engineering; Titania surface engineering; Titania surfaces; Femtosecond lasers | English | 2024 | 2024-12 | 10.3390/app142310913 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Comparative Evaluation of Laser System to Conventional Surgical Approaches in Periodontal Healing Using Optical Coherence Tomography | Background: Optical coherence tomography (OCT) is an emerging, radiation-free diagnostic tool in dentistry, providing high-resolution, real-time imaging of both hard and soft tissues, including periodontal areas, for more accurate postoperative evaluations. This study aims to investigate the efficacy of OCT on periodontal tissues in animals by comparing the healing effects of laser therapy with those of conventional surgical instruments. Methods: Six rabbits underwent periodontal surgery using a laser, scalpel, and punch to perform an apically positioned flap on the mandibular anterior incisors and to create a tongue ulcer on the dorsal surface of the tongue. Visual and OCT evaluations were conducted on days 1, 2, 3, 7, and 14. Results: In periodontal surgery, the laser exhibited slightly faster healing compared to other methods. In tongue ulcer formation, the scalpel and punch groups demonstrated slightly faster healing than that of the laser. However, both methods ultimately showed similar healing outcomes. Conclusions: In the dental field, OCT is emerging as a valuable tool for assessing healing, including early stages of healing, in periodontal therapy. | Park, Jun-Hyeong; Son, Keun-Ba-Da; Son, Young-Tak; Kim, Yong-Gun; Hwang, Sung-Min; Hwang, Jun-Ho; Lee, Jong-Hoon; Kim, Hyun-Deok; Lee, Kyu-Bok; Lee, Jae-Mok | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu 41940, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst A3DI, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Adv Convergence Technol, Daegu 41061, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | ; Son, Keunbada/AAG-8089-2019; SON, Keunbada/AAG-8089-2019; Kim, Yong Joon/IQS-7291-2023 | 58415621300; 57202916520; 57219111205; 55622694400; 57870525500; 57204783286; 57204786073; 55663858300; 15925571200; 17346330000 | bi021499@gmail.com;oceanson@knu.ac.kr;dudxkr741@naver.com;periokyg@knu.ac.kr;lhwangl89@naver.com;hjh@iact.or.kr;laser@knu.ac.kr;hdkim@knu.ac.kr;kblee@knu.ac.kr;leejm@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 19 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 2 | 2 | dental laser system; optical coherence tomography; periodontal healing | CARBON-DIOXIDE LASER; SOFT-TISSUE; THERAPY | dental laser system; optical coherence tomography; periodontal healing | Dental cutting tools; Dentistry; Diagnosis; Laser surgery; Laser tissue interaction; Optical tomography; Transplantation (surgical); Coherence tomography; Comparative evaluations; Dental laser system; Dental lasers; Diagnostics tools; High resolution; Laser systems; Optical-; Periodontal healing; Realtime imaging; Optical coherence tomography | English | 2024 | 2024-10 | 10.3390/app14198854 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Data Augmentation Method Using Room Transfer Function for Monitoring of Domestic Activities | Monitoring domestic activities helps us to understand user behaviors in indoor environments, which has garnered interest as it aids in understanding human activities in context-aware computing. In the field of acoustics, this goal has been achieved through studies employing machine learning techniques, which are widely used for classification tasks involving sound recognition and other objectives. Machine learning typically achieves better performance with large amounts of high-quality training data. Given the high cost of data collection, development datasets often suffer from imbalanced data or lack high-quality samples, leading to performance degradations in machine learning models. The present study aims to address this data issue through data augmentation techniques. Specifically, since the proposed method targets indoor activities in domestic activity detection, room transfer functions were used for data augmentation. The results show that the proposed method achieves a 0.59% improvement in the F1-Score (micro) from that of the baseline system for the development dataset. Additionally, test data including microphones that were not used during training achieved an F1-Score improvement of 0.78% over that of the baseline system. This demonstrates the enhanced model generalization performance of the proposed method on samples having different room transfer functions to those of the trained dataset. | Kim, Minhan; Lee, Seokjin | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 57216617123; 36174416200 | kmh7576@knu.ac.kr;sjlee6@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | machine learning; acoustic scene classification; monitoring of domestic activity; data augmentation | acoustic scene classification; data augmentation; machine learning; monitoring of domestic activity | Contrastive Learning; Acoustic scene classification; Baseline systems; Data augmentation; Domestic activity; F1 scores; High quality; Machine-learning; Monitoring of domestic activity; Room transfer function; Scene classification; Adversarial machine learning | English | 2024 | 2024-11 | 10.3390/app14219644 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Developing a Robust Training Dataset for AI-Driven Architectural Spatial Layout Generation | Recent advancements in AI research, particularly in spatial layout generation, highlight its capacity to enhance human creativity by swiftly providing architects with numerous alternatives during the pre-design phase. The complexity of architectural design data, characterized by multifaceted elements and varying representations, presents significant challenges in creating uniform and robust datasets. This study addresses this challenge by developing a robust training dataset specifically tailored for AI-driven spatial layout generation in architecture. An algorithm capable of extracting spatial relationship diagrams from raster-based floor plan images and converting them into vector-based data was introduced. Through extensive web crawling, a dataset comprising 10,000 data rows, categorized into 21 classes and three spatial relationship categories, was collected. When tested with the You-Only-Look-Once (YOLO) model, the detection rate was 99%, the mean average precision was 85%, and the MIoU was 74.2%. The development of this robust training dataset holds significant potential to advance knowledge-based artificial intelligence design automation studies, paving the way for further innovation in architectural design. | Park, Hyejin; Gu, Hyeongmo; Hong, Soonmin; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea | ; Choo, Seungyeon/JFB-0390-2023 | 57226002455; 57209659182; 57734398300; 36835366900 | phj8598@knu.ac.kr;ghm3186@knu.ac.kr;soonmin_hong@knu.ac.kr;choo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 16 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 2 | 3 | training dataset; architectural spatial layout generation; floor plan detection; spatial relationship diagrams; YOLO model | architectural spatial layout generation; floor plan detection; spatial relationship diagrams; training dataset; YOLO model | Web crawler; Architectural spatial layout generation; Floor plan detection; Floorplans; Layout generations; Robust trainings; Spatial layout; Spatial relationship diagram; Spatial relationships; Training dataset; You-only-look-once model; Architectural design | English | 2024 | 2024-08 | 10.3390/app14167095 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of Architectural Object Automatic Classification Technology for Point Cloud-Based Remodeling of Aging Buildings | In this study, we address the challenge of efficiently handling the maintenance and remodeling of buildings constructed post-1960s, lacking architectural drawings. The conventional approach involves manual measurements and data recording, followed by digital drawing creation. However, we leverage Fourth Industrial Revolution technologies to develop a deep learning-based automatic object classification system using point cloud data. We employ the FCAF3D network with multiscale cells, optimizing its configuration for classifying building components such as walls, floors, roofs, and other objects. While classifying walls, floors, and roofs using bounding boxes led to some boundary-related errors, the model performed well for objects with distinct shapes. Our approach emphasizes efficiency in the remodeling process rather than precise numerical calculations, reducing labor and improving architectural planning quality. While our dataset labeling strategy involved bounding boxes with limitations in numerical precision, future research could explore polygon-based labeling, minimizing loss of space and potentially yielding more meaningful results in classification. In summary, our technology aligns with the initial research objectives, and further investigations could enhance the methodology for even more accurate building object classification. | Kim, Taehoon; Gu, Hyeongmo; Hong, Soonmin; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 58260945000; 57209659182; 57734398300; 36835366900 | thlouiskim@gmail.com;ghm3186@knu.ac.kr;soonmin_hong@knu.ac.kr;choo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.81 | 2025-04-16 | 1 | 2 | aging buildings; remodeling; point cloud; object detection; automatic classification | RECOGNITION | aging buildings; automatic classification; object detection; point cloud; remodeling | English | 2024 | 2024-01 | 10.3390/app14020862 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Developmental Toxicity of C10 Massoia Lactone, the Main Constituent of Cryptocarya massoia, on Zebrafish (Danio rerio) Embryos | C10 massoia lactone (C10) is the main component of massoia essential oil derived from Cryptocarya massoia plant bark, which is used as natural flavoring agent of "generally recognized as safe" status. In this study, the developmental toxicity of C10 was evaluated on zebrafish (Danio rerio) embryos at an exposure level of 0-2000 mu gL-1, and acute toxicity was determined with respect to lethal effects, hatching rates, and morphological changes. Additionally, morphological changes were determined for the endpoints as the occurrence of yolk edema, pericardial edema, spine curvature, and shortened body length after treatment until 96 h post-fertilization (hpf). The complete lethality of C10 was achieved with embryos treated at 2000 mu gL-1, and most embryos treated at 1000 mu gL-1 developed pericardial edemas with some spine curvature. Some embryos exhibited delayed development with shortened body length when compared with the control. Hatchability was completely accomplished at the tested dose of 1000 mu gL-1, and cardiac malformation was observed using a transgenic zebrafish line Tg(cmlc:EGFP), with a lower heartbeat rate in embryos treated with C10 for 72 hpf. After 96 hpf, heartbeat rates were normalized when compared with the control group, and two cardiac development-related genes such as nppa and canca1 were differently expressed in C10-treated embryos by 2.3-fold and 0.4-fold, respectively. Therefore, C10 must be studied further in other higher organisms for its risk. | Lee, Yubin; Kim, Chaeeun; Kim, Tae-Oh; Lee, Sung-Eun | Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kumoh Natl Inst Technol, Dept Environm Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea | Kim, Hyung/J-5451-2012 | 58617076900; 57200245142; 9335312200; 55890041600 | fnrl456@knu.ac.kr;dkrkek01@knu.ac.kr;tokim@kumoh.ac.kr;selpest@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 2 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.4 | 2025-04-16 | 1 | 1 | C10 massoia oil; zebrafish embryos; developmental toxicity; cardiac development; acute toxicity | acute toxicity; C10 massoia oil; cardiac development; developmental toxicity; zebrafish embryos | English | 2024 | 2024-01 | 10.3390/app14020538 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Empirical Trials on Unmanned Agriculture in Open-Field Farming: Ridge Forming | The decreasing rural population and migration to urban areas for high-tech opportunities have weakened the agricultural labor force. While data technology has been adopted in protected agriculture, numerous challenges remain in field agriculture. In this study, we focus on one of the fundamental steps of field operations, i.e., ridge forming, specifically in unmanned agriculture. We compared the performance of a conventional tractor with an implement to that of a ridge-forming robot. The operation data were collected using an acquisition system, and a comparison between the results of both methods was conducted. Additionally, we analyzed the linearity of autonomous driving and the expenses associated with the selected operation. Our findings indicate that the developed robot for ridge forming caused less torque damage and achieved a more accurate target soil depth, with a linearity performance showing a distance error of only 0.267 m. Furthermore, it eliminated the need for hiring an operator and significantly reduced fuel consumption, which accounts for 50.81% of the operational expenses. These results suggest that field operations can be effectively replaced by autonomous systems, and further research on unmanned agriculture is warranted. | Kang, Seokho; Kim, Yonggik; Han, Joonghee; Park, Hyunggyu; Son, Jinho; Han, Yujin; Woo, Seungmin; Ha, Yushin | Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Bioind Mech Engn, Daehak Ro 80, Daegu 41566, South Korea; DGIST, Div Elect & Informat Syst, Techno Jungang Daero 333, Daegu 54875, South Korea; Kyungpook Natl Univ, Upland Field Machinery Res Ctr, Daehak Ro 80, Daegu 41566, South Korea | 57221791368; 58419351400; 36140124500; 57279183700; 57879932100; 59306805000; 57192074884; 57192072314 | deshshk@knu.ac.kr;dydwlr9988@knu.ac.kr;jhhan@dgist.ac.kr;pyd4796@knu.ac.kr;thsghqks@knu.ac.kr;yjhan33@knu.ac.kr;kooger7571@naver.com;yushin72@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0 | 2025-05-07 | 0 | 0 | field robot; replaceability; unmanned agriculture | field robot; replaceability; unmanned agriculture | Agricultural labors; Field operation; Field robot; High tech; Performance; Replaceability; Rural migration; Rural population; Unmanned agriculture; Urban areas; Agricultural robots | English | 2024 | 2024-09 | 10.3390/app14188155 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Enhanced Conversion Efficiency in MAPbI3 Perovskite Solar Cells through Parameters Optimization via SCAPS-1D Simulation | In this study, various factors affecting the efficiency of the MAPbI(3) perovskite solar cell (PSC) were analyzed using the SCAPS-1D simulation program. The basic device analyzed in this study had a structure of ITO/TiO2/MAPbI(3)/Cu2O/Au. The thickness of each layer (electron transport layer (ETL), perovskite absorption layer (PAL), and hole transport layer (HTL)), PAL defect density and interface defect density were investigated as parameters. The optimized parameters that yielded the highest light conversion efficiency were an ETL (TiO2) thickness of 100 nm, a PAL (MAPbI(3)) thickness of 1300 nm, an HTL (Cu2O) thickness of 400 nm, a PAL defect density of 10(14) cm(-3), and an interface defect density of 10(13) cm(-3) for both absorber/ETL and absorber/HTL interfaces. The optimized PSC exhibited a maximum efficiency of 19.30%. These results obtained in this study are expected to contribute considerably to the optimization and efficiency improvement of perovskite solar cells using inorganic charge-carrier transport layers. | Son, Chaerin; Son, Hyojung; Jeong, Byoung-Seong | Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Adv Mat Res Inst, Daegu 41566, South Korea | 59091533600; 57902836700; 35895071700 | gatorever@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 6 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 4.03 | 2025-05-07 | 14 | 14 | perovskite photovoltaic solar cell; MAPbI(3); TiO2; Cu2O; power conversion efficiency | NUMERICAL-SIMULATION; HALIDE PEROVSKITES; ABSORBER LAYER; CU2O; PERFORMANCE | Cu<sub>2</sub>O; MAPbI<sub>3</sub>; perovskite photovoltaic solar cell; power conversion efficiency; TiO<sub>2</sub> | English | 2024 | 2024-03 | 10.3390/app14062390 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Enhancing Inter-Patient Performance for Arrhythmia Classification with Adversarial Learning Using Beat-Score Maps | Research on computer-aided arrhythmia classification is actively conducted, but the limited generalization capacity constrains its applicability in practical clinical settings. One of the primary challenges in deploying such techniques in real-world scenarios is the inter-patient variability and the consequent performance degradation. In this study, we leverage our previous innovation, the n-beat-score map (n-BSM), to introduce an adversarial framework to mitigate the issue of poor performance in arrhythmia classification within the inter-patient paradigm. The n-BSM is a 2D representation of the ECG signal, capturing its constituent beat characteristics through beat-score vectors derived from a pre-trained beat classifier. We employ adversarial learning to eliminate patient-dependent features during the training of the beat classifier, thereby generating the patient-independent n-BSM (PI-BSM). This approach enables us to concentrate primarily on the learning characteristics associated with beat type rather than patient-specific features. Through a beat classifier pre-trained with adversarial learning, a series of beat-score vectors are generated for the beat segments that make up a given ECG signal. These vectors are then concatenated chronologically to form a PI-BSM. Utilizing PI-BSMs as the input, an arrhythmia classifier is trained to differentiate between distinct types of rhythms. This approach yields a 14.27% enhancement in the F1-score in the MIT-BIH arrhythmia database and a 4.97% improvement in cross-database evaluation using the Chapman-Shaoxing 12-lead ECG database. | Jeong, Yeji; Lee, Jaewon; Shin, Miyoung | Kyungpook Natl Univ, Grad Sch Elect & Elect Engn, Biointelligence & Data Min Lab, Daegu 41566, South Korea | 59302934500; 58377059800; 7401536642 | yeji7102@naver.com;realjaewon94@gmail.com;shinmy@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 16 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.73 | 2025-05-07 | 2 | 2 | arrhythmia classification; ECG individual differences; inter-patient scheme; adversarial learning | ECG CLASSIFICATION; NETWORK | adversarial learning; arrhythmia classification; ECG individual differences; inter-patient scheme | Contrastive Learning; Database systems; Electrocardiography; Generative adversarial networks; Adversarial learning; Arrhythmia classification; Clinical settings; Computer-aided; ECG individual difference; ECG signals; Generalization capacity; Individual Differences; Inter-patient scheme; Performance; Adversarial machine learning | English | 2024 | 2024-08 | 10.3390/app14167227 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Eucalyptus in Agriculture: Friend or Foe? Analyzing its impact on crop yields, soil dynamics, and farmers' perceptions in Bangladesh | Eucalyptus has emerged as a game-changer in Bangladesh's forestry sector due to its high productivity in dry and infertile areas. To understand farmers' preference for eucalyptus despite government bans, comprehensive surveys and on-farm experiments were conducted in Dinajpur, Bangladesh. Additionally, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU) conducted small-scale field and pot experiments to evaluate the allelopathic impacts of eucalyptus roots, bark, and leaf extracts on rice yield during the Boro and Aus seasons. Our survey revealed that, despite challenges like water competition, leaf contamination, hindered tillage, and reduced soil fertility, farmers successfully grow rice, maize, potato, tomato, mustard, and grass alongside eucalyptus trees. Farmers are motivated by eucalyptus's potential to enhance economic returns, evidenced by a high benefit-cost ratio of 1.22-1.81 and a 10-year net compensation of US$5552-9918, even after yield losses. Our Dinajpur field experiment showed that rice yield was relatively unaffected at 5 m from the tree base, but closer distances reduced yield by 56.77 and 42.10% in Boro and Aus seasons, respectively, compared with sole rice systems. Field and pot experiments at BSMRAU showed a severe decline in rice yields with increasing tree leaf coverage and eucalyptus extract concentrations (0 to 100% concentration), likely due to allelochemicals. Surprisingly, areas near the eucalyptus base showed enhanced total nitrogen and organic carbon levels, credited to substantial leaf litter deposition. Our research decisively proves that eucalyptus and eucalyptus-based agroforestry systems boost farmers' socio-economic status by offering valuable forest resources and debunking harmful misconceptions. | Rahman, Md.

| ○ | ○ | Article | Examining Modulations of Internal Tides within An Anticyclonic Eddy Using a Wavelet-Coherence Network Approach | Interactions between internal tides and mesoscale eddies are an important topic. However, examining modulations of internal tides inside a mesoscale eddy based on observations is difficult due to limited observation duration and inaccurate positioning within the eddy. In order to overcome these two practical limitations, we use the active navigation capability of underwater gliders to conduct measurements inside the targeted eddy and utilize the wavelet approach to investigate modulations of internal tides with diurnal and semidiurnal periods inside the eddy. Based on the wavelet's frequency-time locality, we construct scale-specific networks via wavelet coherence (WC) from multivariate timeseries with a small sample size. The modulation of internal tides is then examined in terms of temporal evolutionary characteristics of the WC network's topological structure. Our findings are as follows: (1) the studied eddy is vertically separated into two layers, the upper (400 m) layers, indicating that the eddy is surface intensified; (2) the eddy is also horizontally divided into two domains, the inner and outer centers, where the modulation of internal tides seems to actively occur in the inner center; and (3) diurnal internal tides are more strongly modulated compared to semidiurnal ones, indicating the influence of spatial scales on the strength of interactions between internal tides and eddies. | Lim, Gyuchang; Park, Jong-Jin | Kyungpook Natl Univ, Kyungpook Inst Oceanog, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Earth Syst Sci, Daegu 41566, South Korea | Park, Jongjin/AAL-3484-2021 | 59883551700; 55717016100 | gclim@knu.ac.kr;jjpark@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 14 | 3 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2024 | 2.5 | 28.3 | 0.37 | 2025-05-07 | 1 | 1 | internal tides; mesoscale eddies; underwater glider; wavelet coherence; complex network theory | PROPAGATION; CIRCULATION; ENERGY | complex network theory; internal tides; mesoscale eddies; underwater glider; wavelet coherence | English | 2024 | 2024-02 | 10.3390/app14031001 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
