| ○ | Article | Stability of immediately loaded 3 mm long miniscrew implants: A feasibility study | Introduction: Shorter miniscrew implants (MSIs) are needed to make orthodontics more effective and efficient. Objective: To evaluate the stability, insertion torque, removal torque and pain associated with 3 mm long MSIs placed in humans by a novice clinician. Methods: 82 MSIs were placed in the buccal maxillae of 26 adults. Pairs of adjacent implants were immediately loaded with 100g. Subjects were recalled after 1, 3, 5, and 8 weeks to verify stability and complete questionnaires pertaining to MSI-related pain and discomfort. Results: The overall failure rate was 32.9%. The anterior and posterior MSIs failed 35.7% and 30.0% of the time, respectively. Excluding the 10 MSIs (12.2%) that were traumatically dislodged, the failure rates in the anterior and posterior sites were 30.1% and 15.2%, respectively; the overall primary failure rate was 23.6%. Failures were significantly (p = 0.010) greater (46.3% vs 19.5%) among the first 41 MSIs than the last 41 MSIs that were placed. Excluding the traumatically lost MSIs, the failures occurred on or before day 42. Subjects experienced very low pain (2.2% of maximum) and discomfort (5.5% of maximum) during the first week only. Conclusions: Shorter 3 mm MSIs placed by a novice operator are highly likely to fail. However, failure rates can be substantially decreased over time with the placement of more MSIs. Pain and discomfort experienced after placing 3 mm MSIs is minimal and temporary. © 2021, Dental Press Editora Ltda.

| ○ | Review | Standardization of the pathologic diagnosis of appendiceal mucinous neoplasms | Although the understanding of appendiceal mucinous neoplasms (AMNs) and their relationship with disseminated peritoneal mucinous disease have advanced, the diagnosis, classification, and treatment of AMNs are still confusing for pathologists and clinicians. The Gastrointestinal Pathology Study Group of the Korean Society of Pathologists (GPSG-KSP) proposed a multicenter study and held a workshop for the “Standardization of the Pathologic Diagnosis of the Appendiceal Mucinous Neoplasm” to overcome the controversy and potential conflicts. The present article is focused on the diagnostic criteria, terminologies, tumor grading, pathologic staging, biologic behavior, treatment, and prognosis of AMNs and disseminated peritoneal mucinous disease. In addition, GPSG-KSP proposes a checklist of standard data elements of appendiceal epithelial neoplasms to standardize pathologic diagnosis. We hope the present article will provide pathologists with updated knowledge on how to handle and diagnose AMNs and disseminated peritoneal mucinous disease. © 2021 The Korean Society of Pathologists/The Korean Society for Cytopathology. | Kang, Dong-Wook; Kim, Baek-Hui; Kim, Joon Mee; Kim, Jihun; Chang, Hee Jin; Chang, Mee Soo; Sohn, Jin-Hee; Cho, Mee-Yon; Jin, So-Young; Chang, Hee Kyung; Han, Hye Seung; Kim, Jung Yeon; Kim, Hee Sung; Park, Do Youn; Park, Ha Young; Lee, So Jeong; Lee, Wonae; Lee, Hye Seung; Kang, Yoo Na; Choi, Younghee | Department of Pathology, Chungnam National University Sejong Hospital, Chungnam National University College of Medicine, Daejeon, South Korea; Department of Pathology, Korea University Guro Hospital, Korea University College of Medicine, Seoul, South Korea; Department of Pathology, Inha University School of Medicine, Incheon, South Korea; Department of Pathology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, South Korea; Department of Pathology, Research Institute and Hospital, National Cancer Center, Goyang, South Korea; Department of Pathology, Seoul National University Boramae Hospital, Seoul National University College of Medicine, Seoul, South Korea; Department of Pathology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, South Korea; Department of Pathology, Yonsei University, Wonju College of Medicine, Wonju, South Korea; Department of Pathology, Soonchunhyang University Seoul Hospital, Seoul, South Korea; Department of Pathology, Kosin University Gospel Hospital, Kosin University College of Medicine, Busan, South Korea; Department of Pathology, Konkuk University School of Medicine, Seoul, South Korea; Department of Pathology, Inje University Sanggye Paik Hospital, Seoul, South Korea; Department of Pathology, Chung-Ang University School of Medicine, Seoul, South Korea; Department of Pathology, St. Maria Pathology, Busan, South Korea; Department of Pathology, Busan Paik Hospital, Inje University College of Medicine, Busan, South Korea; Department of Pathology, Pusan National University Hospital, Pusan National University School of Medicine, Busan, South Korea; Department of Pathology, Dankook University College of Medicine, Cheonan, South Korea; Department of Pathology, Seoul National University College of Medicine, Seoul, South Korea; Department of Forensic Medicine, Kyungpook National University School of Medicine, Daegu, South Korea; Department of Pathology, Hallym University Dongtan Sacred Heart Hospital, Hwaseong, South Korea | 55885804400; 16203115900; 57554573600; 57222101434; 9335381400; 7404504590; 57216200092; 7401727574; 35590135600; 12778283700; 57226216335; 56847908400; 57204311736; 57205289656; 57201862680; 56803982700; 55973619400; 57102095800; 7402784356; 55685949600 | jmkpath@inha.ac.kr; | Journal of Pathology and Translational Medicine | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 55 | 4 | ESCI | PATHOLOGY | 2021 | N/A | 0.45 | 2025-07-30 | 11 | Appendiceal mucinous neoplasm; Disseminated peritoneal mucinous disease; Pathologic diagnosis; Standardization | appendiceal mucinous neoplasm; appendix cancer; cancer grading; cancer prognosis; cancer staging; colloid carcinoma; disease classification; epithelium tumor; goblet cell metaplasia; histology; histopathology; human; nomenclature; pathogenesis; pathologist; peritoneum; peritoneum pseudomyxoma; Research Diagnostic Criteria; Review; standardization | English | Final | 2021 | 10.4132/jptm.2021.05.28 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | ○ | Review | Standardized pathology report for breast cancer | Given the recent advances in management and understanding of breast cancer, a standardized pathology report reflecting these changes is critical. To meet this need, the Breast Pathology Study Group of the Korean Society of Pathologists has developed a standardized pathology reporting format for breast cancer, consisting of 'standard data elements,' 'conditional data elements,' and a biomarker report form. The 'standard data elements' consist of the basic pathologic features used for prognostication, while other factors related to prognosis or diagnosis are described in the 'conditional data elements.' In addition to standard data elements, all recommended issues are also presented. We expect that this standardized pathology report for breast cancer will improve diagnostic concordance and communication between pathologists and clinicians, as well as between pathologists inter-institutionally. | Cho, Soo Youn; Park, So Yeon; Bae, Young Kyung; Kim, Jee Yeon; Kim, Eun Kyung; Kim, Woo Gyeong; Kwon, Youngmee; Lee, Ahwon; Lee, Hee Jin; Lee, Ji Shin; Park, Jee Young; Gong, Gyungyub; Yoon, Hye Kyoung | Sungkyunkwan Univ, Samsung Med Ctr, Dept Pathol & Translat Genom, Sch Med, Seoul, South Korea; Seoul Natl Univ, Bundang Hosp, Coll Med, Dept Pathol, Seongnam, South Korea; Yeungnam Univ, Dept Pathol, Coll Med, Daegu, South Korea; Pusan Natl Univ, Yangsan Hosp, Coll Med, Dept Pathol, Yangsan, South Korea; Eulji Univ, Dept Pathol, Coll Med, Seoul, South Korea; Inje Univ, Dept Pathol, Haeundae Paik Hosp, Busan, South Korea; Natl Canc Ctr, Dept Pathol, Goyang, South Korea; Catholic Univ Korea, Coll Med, Seoul St Marys Hosp, Dept Hosp Pathol, Seoul, South Korea; Univ Ulsan, Asan Med Ctr, Dept Pathol, Coll Med, Seoul, South Korea; Chonnam Natl Univ, Dept Pathol, Med Sch, Gwangju, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Inje Univ, Busan Paik Hosp, Dept Pathol, 75 Bokji Ro, Busan 47392, South Korea | Kim, Jong-Yeup/ISA-2120-2023; Kim, Jee/J-5441-2012; Park, Jung Hwan/AAA-1951-2022; Park, So/A-2621-2012 | 7404885257; 57049820300; 56638779000; 57191685703; 56612558600; 56402145600; 8591902500; 35218106600; 56424275700; 55665972300; 57226185359; 7103214892; 8557069600 | pathyoon@inje.ac.kr; | JOURNAL OF PATHOLOGY AND TRANSLATIONAL MEDICINE | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 55 | 1 | ESCI | PATHOLOGY | 2021 | N/A | 0.15 | 2025-07-30 | 7 | 5 | Breast neoplasms; Diagnosis; Pathology report | TUMOR-INFILTRATING LYMPHOCYTES; FACTOR RECEPTOR 2; DUCTAL CARCINOMA; PROGNOSTIC-SIGNIFICANCE; INDUCTION CHEMOTHERAPY; AMERICAN SOCIETY; SPECIMENS; RECOMMENDATIONS; CLASSIFICATION; GUIDELINE | biological marker; epidermal growth factor receptor; estrogen receptor; Ki 67 antigen; progesterone receptor; breast cancer; breast tissue; cancer classification; cancer diagnosis; cancer grading; cancer prognosis; cancer size; cancer staging; female; histology; human; intraductal carcinoma; lumpectomy; lymph node metastasis; lymph vessel metastasis; medical documentation; microcalcification; nuclear size; partial mastectomy; pathologist; perineural invasion; Review; simple mastectomy; standardization; surgical margin; therapy effect; tumor associated leukocyte; wide excision | English | 2021 | 2021-01 | 10.4132/jptm.2020.11.20 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Proceedings Paper | State of Charge Estimation and State of Health Diagnostic Method Using Multilayer Neural Networks | Lithium batteries are the most common energy storage devices in fields such as electric vehicles, portable devices, and energy storage systems. Continuously using the battery in a degradation state creates a fire or explosion risk. To prevent such accidents, research on a battery management system (BMS) that diagnoses the state of a battery was conducted. This study proposes a method that uses multilayer neural networks (MNN) for state of charge (SOC) estimation and state of health (SOH) diagnosis. The proposed method uses four MNN models as SOH diagnostic models and three SOC estimation models. Each SOC estimation model comprises a normal model, a caution model, and a fault model according to the learned data based on the output result of the SOH diagnostic model. From the experiments, the proposed method estimates and diagnoses SOC and SOH well. | Lee, Jong-Hyun; Kim, Hyun-Sil; Lee, In-Soo | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu, South Korea; Naval Combat Syst PMO Agcy Def Dev, Daejeon, South Korea | Lee, jaeho/ABE-6242-2020 | 57201265019; 57216619327; 54979862300 | 2021 INTERNATIONAL CONFERENCE ON ELECTRONICS, INFORMATION, AND COMMUNICATION (ICEIC) | 2.45 | 2025-07-30 | 9 | 12 | lithium battery; state of health; state of charge; multilayer deep neural network; estimation method | BATTERY | Estimation method; Lithium battery; Multilayer deep neural network; State of charge; State of health | Charging (batteries); Digital storage; Energy storage; Lithium batteries; Multilayer neural networks; Multilayers; Degradation state; Diagnostic methods; Diagnostic model; Energy storage systems; Portable device; SOC estimations; State of charge; State-of-charge estimation; Battery management systems | English | 2021 | 2021 | 10.1109/iceic51217.2021.9369782 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||

| ○ | ○ | Article; Proceedings Paper | Strategy for salvaging infected breast implants: lessons from the recovery of seven consecutive patients | Background In recent years, implant-based breast reconstruction has been performed because of its simplicity, short operation time, and rapid recovery of patients. Several studies have reported treatment methods for implant surgery-related infection, which is a serious complication. The aim of this study was to introduce our strategy for salvaging infected implants and to evaluate its effectiveness. Methods The authors performed a retrospective study of 145 cases from 132 patients who underwent implant-based breast reconstruction from January 2012 to December 2018. Empirical antibiotics were immediately administered to patients with suspected infections. The patients then underwent salvage treatment including appropriate antibiotics, ultrasonography-guided aspiration, debridement, antibiotic lavage, and implant exchange through a multidisciplinary approach. Patient demographics, operative data, duration until drain removal, adjuvant treatment, and complications were analyzed. Results The total infection rate was 5.5% (8/145). A longer indwelling catheter period and adjuvant treatment were significantly associated with infection. The salvage treatment showed a success rate of 87.5% (7/8). Seven patients who received early aggressive salvage treatment recovered from infection. One patient with methicillin-resistant Staphylococcus aureus, who received salvage treatment 11 days after symptom onset, did not respond to drainage and antibiotic treatment. That patient subsequently underwent explantation. Conclusions In implant-based breast reconstruction, prevention of infection is of the utmost importance. However, if an infection is suspected, proactive empirical antibiotic therapy and collaboration with the necessary departments are required. Through a multidisciplinary approach and proactive early management, swift and appropriate salvage should be performed. | Yeo, Hyeonjung; Lee, Dongkyu; Kim, Jin Soo; Eo, Pil Seon; Kim, Dong Kyu; Lee, Joon Seok; Kwon, Ki Tae; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug | Daegu Fatima Hosp, Dept Plast & Reconstruct Surg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Plast & Reconstruct Surg, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Div Infect Dis, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Surg, Daegu, South Korea | ; Kim, Ho Jin/IZP-7210-2023; Lee, Jong-Mok/KVY-9550-2024; LEE, JIN/Q-3108-2018; Kim, Hanjin/KYP-2633-2024; Yang, Jung/R-7806-2019 | 35727375800; 57222624163; 57205627627; 57205401706; 57192908794; 56496041000; 9733850500; 37079213100; 56564377200; 55171704700 | lambyang@knu.ac.kr; | ARCHIVES OF PLASTIC SURGERY-APS | ARCH PLAST SURG-APS | 2234-6163 | 2234-6171 | 48 | 2 | ESCI | SURGERY | 2021 | N/A | 0.99 | 2025-07-30 | 9 | 9 | Mammaplasty; Breast implants; Infections; Salvage therapy; Interdisciplinary studies | POSTOPERATIVE COMPLICATIONS; RECONSTRUCTION; PROSTHESIS; MASTECTOMY; EXPERIENCE; MANAGEMENT; IMMEDIATE | Breast implants; Infections; Interdisciplinary studies; Mammaplasty; Salvage therapy | C reactive protein; cefazolin; cefpodoxime proxetil; ciprofloxacin; entecavir; piperacillin plus tazobactam; povidone iodine; rifampicin; sultamicillin; vancomycin; adjuvant therapy; adult; antibiotic therapy; Article; breast augmentation; breast cancer; breast implant rupture; breast reconstruction; case report; cellulitis; clinical article; computer assisted tomography; debridement; drug substitution; echography; echomammography; edema; endoscopic ultrasound guided fine needle biopsy; erythema; female; follow up; graft necrosis; hematoma; human; implant capsular contracture; leukocyte count; methicillin resistant Staphylococcus aureus; necrosis; nuclear magnetic resonance imaging; operation duration; postoperative care; Pseudomonas infection; pus; salvage therapy; sepsis; seroma; Staphylococcus infection; surgical debridement; surgical infection; treatment response; wound dehiscence; wound healing; wound infection | English | 2021 | 2021-03 | 10.5999/aps.2020.01578 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Strengths of Struts and Nodal Zones for Strut-and-Tie Model Design of Reinforced Concrete Corbels | The strut-and-tie model (STM) method is useful for the limit state design of reinforced concrete (RC) corbels. However, for the rational design of RC corbels, designers must accurately determine the strengths of concrete struts and nodal zones to check the strength conditions of a selected STM and the anchorage of reinforcing bars in nodal zones. In this study, the authors suggested a numerical process for determining the strengths of concrete struts and nodal zones in RC corbel STMs. The technique incorporates the state of two-dimensional (2-D) stresses at the strut and nodal zone locations, 2-D failure envelope of concrete, deviation angle between the strut orientation and compressive principal stress trajectory, and the effect of concrete confinement by reinforcing bars. The authors also proposed the strength equations of struts and nodal zones that apply to the typical determinate and indeterminate STMs of RC corbels. The authors considered the effects of the shear span-to-effective depth ratio, the horizontal-to-vertical load ratio, and the primary tensile and horizontal shear reinforcement ratios in developing the strength equations. The authors predicted the failure strengths of 391 RC corbels tested to examine the appropriateness of the proposed numerical process and strength equations. The predicted failure strength compares very well with experimental results, proving that the rational analysis and design of RC corbels are possible by using the present study's strut and nodal zone strengths. | Yun, Young Mook; Lee, Youjong | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | 7201731110; 57236620700 | ymyun@knu.ac.kr; | CIVIL ENGINEERING JOURNAL-TEHRAN | CIV ENG J-TEHRAN | 2676-6957 | 2476-3055 | 7 | 8 | ESCI | ENGINEERING, CIVIL | 2021 | N/A | 0.4 | 2025-07-30 | 6 | 7 | Reinforce Concrete Corbel; Strut-and-Tie Model; Concrete Strut; Nodal Zone | STEEL FIBERS; BEHAVIOR | Concrete Strut; Nodal Zone; Reinforce Concrete Corbel; Strut-and-Tie Model | English | 2021 | 2021-08 | 10.28991/cej-2021-03091725 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Structural equation modeling analysis on health literacy and cancer prevention behaviors among medically-underserved, low-income populations | Purpose: The purpose of this study was to test a hypothetical model about health literacy and cancer preventive behaviors among medically-underserved, low-income populations. Methods: Data were collected by questionnaire survey from 284 medical aid beneficiaries in three metropolitan cities from August to September 2018. Based on Von Wagner's health literacy and health outcome framework, the hypothetical model was developed which designates health literacy as the exogenous variable, cancer preventive behaviors as the endogenous variables, and knowledge, beliefs and attitudes about cancer prevention, and self-efficacy for mediating variables. Structural modeling analysis was conducted using SPSS/WIN 21.0 and AMOS 25.0 program. Results: Health literacy had a significant direct effect on knowledge, beliefs and attitude about cancer prevention, and self-efficacy but not on cancer preventive behaviors. Knowledge, beliefs and attitudes about cancer prevention, and self-efficacy, fully mediated in the relationship between health literacy and cancer preventive behaviors. Model fit indices for the hypothetical model showed good agreement. Conclusion: Health literacy among the medically-underserved, low-income populations influences cancer preventive behaviors through the full mediation of knowledge, beliefs and attitude, and self-efficacy. Therefore, to promote cancer preventive behaviors among medically-underserved, low-income populations, consideration should be given to health literacy level and development of strategies to enhance knowledge, beliefs and attitudes, and self-efficacy. © 2021 Journal of the Korean Academy of Fundamentals of Nursing. | Kim, Eun Jin; Kim, Su Hyun | Department of Nursing, Suseong University, Daegu, South Korea; College of Nursing Research Institute of Nursing Science, Kyungpook National University, Daegu, South Korea | 57223914109; 56664542600 | suhyun_kim@knu.ac.kr; | Journal of the Korean Academy of Fundamentals of Nursing | 1225-9012 | 28 | 1 | 0 | 2025-07-30 | 0 | Attitude; Health literacy; Knowledge; Neoplasms; Self-efficacy | Korean | Final | 2021 | 10.7739/jkafn.2021.28.1.83 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Structural, morphological, optical, and photosensing properties of Cs2TeI6 thin film synthesized by two-step dry process | Recently, cesium tellurium iodine (Cs2TeI6) has emerged as an inorganic halide perovskite material with potential application in optoelectronic devices due to its high absorption coefficient, suitable bandgap and because it consists of nontoxic and earth-abundant elements. However, studies on its fabrication process as well as photoresponse characteristics are limited. In this study, a simple and effective method is introduced for the synthesis of Cs2TeI6 thin films by a two-step dry process. A Cs2TeI6-based lateral photosensor was fabricated, and its photoresponse characteristics were explored under laser illuminations of four different wavelengths in the visible range: 405, 450, 520, and 655 nm. The initial photosensing results suggest potential application and can lead to more promising studies of Cs2TeI6 film in optoelectronics. © 2023 The Authors. | Hoat, Phung Dinh; Van Khoe, Vo; Bae, Sung-Hoon; Lim, Hyo-Jun; Hung, Pham Tien; Heo, Young-Woo | School of Materials Science and Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea; Department of Physics, Le Quy Don Technical University, No. 236 Hoang Quoc Viet Street, Hanoi, 100000, Viet Nam; School of Materials Science and Engineering, Kyungpook National University (KNU), 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea, KNU Advanced Material Research Institute, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, 41566, South Korea | 57209732166; 58569093500; 57209245291; 57338060200; 57194216208; 7004298542 | ywheo@knu.ac.kr; | Journal of Sensor Science and Technology | 1225-5475 | 30 | 5 | 0.36 | 2025-07-30 | 4 | Cesium tellurium iodide (Cs2TeI6); Chemical vapor deposition (CVD); Halide perovskite; Lead-free; Non-solution method; Photosensing properties | English | Final | 2021 | 10.46670/jsst.2021.30.5.279 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Study of the luminescence Properties of Dy3+or Sm3+doped Lu2Gd1Ga2Al3O12Phosphors for X-ray Imaging | In this study, the Lu2Gd1Ga2Al3O12phosphor was fabricated using the solid-state reaction method, and its luminescence characteristics were studied. To confirm the crystallinity and the grain size of the Lu2Gd1Ga2Al3O12phosphor, an X-ray difraction (XRD) and FE-SEM was measured . The emission spectra of the Lu2Gd1Ga2Al3O12phosphor was measured using X-ray and UV light sources. The results comfirmed that the main peaks of Lu2Gd1Ga2Al3O12:Sm3+and Lu2Gd1Ga2Al3O12:Dy3+were between 550 to 750 nm and 450 to 800 nm, respectively. Lastly, the decay time was measured and compared to Lu2Gd1Ga2Al3O12:Sm3+and Lu2Gd1Ga2Al3O12:Dy3+phosphor. The luminescence spectra result of the X-ray was coincident to UV light sources. The Lu2Gd1Ga2Al3O12phosphor is composed of rare earth elements such as Gd2O3and Lu2O3, which have a high effective atomic Z numbers (Zeff= 55) and high detection efficiency for X-rays and gamma rays. Therefore, phosphar can be applied in fields of medical diagnostic imaging. © 2021 The Korean Physical Society.

| ○ | Article | Study of the method to minimize switching loss by individual control of parallel switches | Generally, high-power inverters are composed of power semiconductors connected in parallel such as an IGBT. The simplest way to control semiconductors connected in parallel is to control all switches with the same switching sequence. However, this control method can cause high switching losses in all switches and imbalance in life among switches. This paper proposes switching patterns that minimize switching losses by individual control of the switches. Different switching losses are calculated depending on the switching pattern and compared by experiment. Through this process, switching patterns that minimize losses are analyzed. Experimental results show that the overall inverter efficiency can be increased with the proposed method under the various current conditions.

| ○ | ○ | Proceedings Paper | Study on deep CNN as preprocessing for video compression | In the recent years, video compression and picture quality have become more intense topic in research areas. In addition, user prerequisite for better resolution and higher quality video compression is increasing. Versatile video coding (VVC) is the latest emerging video coding standard specially designed for video compression. However, its frequency-based transform techniques are vulnerable on high-frequency noise, which results in increased bitrate or low picture quality. To resolve such unintended attack, we apply denoising convolutional neural network (DnCNN) to input video of codecs as a preprocessing since the DnCNN model was studied for image denoising with the capability of handling Gaussian denoising with residual learning strategy. In this paper we demonstrate experimental results that how DnCNN model helps for noised video data in terms of quality and bitrate. | Bhosale, Kavita Arjun; Kuk, Seungho; Park, Sang-hyo | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Theragen Bio, Seongnam, South Korea | 57326071700; 57325876100; 55362514700 | s.park@knu.ac.kr; | APPLICATIONS OF DIGITAL IMAGE PROCESSING XLIV | 0277-786X | 1996-756X | 11842 | 0.93 | 2025-07-30 | 0 | 2 | Video compression; preprocessing; deep learning; denoising; video quality; HEVC | Deep learning; Denoising; HEVC; Preprocessing; Video compression; Video quality | Deep learning; Image coding; Image denoising; Neural networks; Video signal processing; Bit rates; Compression quality; Convolutional neural network; De-noising; Deep learning; HEVC; Neural network model; Picture quality; Preprocessing; Video quality; Image compression | English | 2021 | 2021 | 10.1117/12.2596227 | 바로가기 | 바로가기 | 바로가기 |
