| ○ | ○ | Review | Tumor immune response and immunotherapy in gastric cancer | Remarkable developments in immuno-oncology have changed the landscape of gastric cancer (GC) treatment. Because immunotherapy intervenes with tumor immune response rather than directly targeting tumor cells, it is important to develop a greater understanding of tumor immunity. This review paper summarizes the tumor immune reaction and immune escape mechanisms while focusing on the role of T cells and their co-inhibitory signals, such as the immune checkpoint molecules programmed death-1 and programmed death-ligand 1 (PD-L1). This paper also describes past clinical trials of immunotherapy for patients with GC and details their clinical implications. Strong predictive markers are essential to improve response to immunotherapy. Microsatellite instability, Epstein-Barr virus, PD-L1 expression, and tumor mutational burden are now regarded as potent predictive markers for immunotherapy in patients with GC. Novel immunotherapy and combination therapy targeting new immune checkpoint molecules such as lymphocyte-activation gene 3, T cell immunoglobulin, and mucin domain containing-3, and indoleamine 2,3-dioxygenase have been suggested, and trials are ongoing to evaluate their safety and efficacy. Immunotherapy is an important treatment option for patients with GC and has great potential for improving patient outcome, and further research in immuno-oncology should be carried out. | Kwak, Yoonjin; Seo, An Na; Lee, Hee Eun; Lee, Hye Seung | Seoul Natl Univ Hosp, Dept Pathol, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Pathol, Seoul, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, Daegu, South Korea; Mayo Clin, Div Anat Pathol, Rochester, MN USA; Seoul Natl Univ, Bundang Hosp, Dept Pathol, Seongnam, South Korea | Kwak, Yoonjin/HOI-0139-2023; Lee, Hye Seung/LZI-3726-2025 | 56049775700; 55804153700; 7501477989; 57102095800 | hye2@snu.ac.kr; | JOURNAL OF PATHOLOGY AND TRANSLATIONAL MEDICINE | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 54 | 1 | ESCI | PATHOLOGY | 2020 | N/A | 2.76 | 2025-06-25 | 71 | 70 | Stomach neoplasms; Immunotherapy; Programmed cell death-ligand 1; Microsatellite instability; Epstein-Barr virus; Tumor mutational burden; Tumor-infiltrating lymphocytes; Biomarker | MICROSATELLITE INSTABILITY STATUS; EXPRESSION-BASED CLASSIFICATION; LYMPHOCYTE-ACTIVATION GENE-3; PROGNOSTIC IMPLICATIONS; MUTATIONAL BURDEN; INFILTRATING LYMPHOCYTES; PROTEIN EXPRESSION; MISMATCH REPAIR; PD-1 BLOCKADE; T-CELLS | Biomarker; Epstein-Barr virus; Immunotherapy; Microsatellite instability; Programmed cell death-ligand 1; Stomach neoplasms; Tumor mutational burden; Tumor-infiltrating lymphocytes | immunological antineoplastic agent; programmed death 1 ligand 1; programmed death 1 ligand 2; cancer immunotherapy; cancer prognosis; Epstein Barr virus; human; immune evasion; immune response; immunosurveillance; microsatellite instability; Review; solid malignant neoplasm; stomach cancer; tumor associated leukocyte; tumor microenvironment; tumor mutational burden; whole exome sequencing | English | 2020 | 2020-01 | 10.4132/jptm.2019.10.08 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Book chapter | Two-dimensional materials for photocatalytic water splitting and CO2 reduction | Considering the increased energy consumption with tremendously growing population and industrialization, incorporation of abundant and clean energy systems in the energy mix is an absolute and prime requisite for sustainability of the emergent civilization. Currently 90% of the energy used globally is generated from carbon-based highly polluting fuels. However, fossil fuels like oil, coal, and gas reservoirs are a limited resource and will eventually become extinct. Moreover, combustion of fossil fuels is a major source of CO2 emission and greenhouse effect which are a major environmental threat. Therefore alternative clean, rich, and sustainable energy conversion, conservation, and storage strategies are required to be implemented on a rather urgent basis. The solutions are expected to come through materials innovations which embody interdisciplinary research. © 2020 Elsevier Inc. | Bhosale, Reshma; Tonda, Surendar; Kumar, Santosh; Ogale, Satishchandra B. | Department of Physics, Centre for Energy Science, Indian Institute of Science Education and Research, Pune, India, College of Engineering Pune, Pune, India; Department of Environmental Engineering, Kyungpook National University, Daegu, South Korea; Department of Chemical Engineering, Imperial College London, London, United Kingdom; Department of Physics, Centre for Energy Science, Indian Institute of Science Education and Research, Pune, India, Research Institute for Sustainable Energy (RISE), TCG-Centres of Research and Edication in Science and Technology, Sector V, Salt lake, Kolkata, 700091, India, Indian Institute of Science Education and Research, Dr. Homi Bhabha Road, Pune, 411008, India, Centre for Clean and Renewable Energy, Indian Institute of Science Education and Research (IISER), India | 37260970400; 56114866900; 55371242400; 55157007700 | Nanostructured Photocatalysts: From Materials to Applications in Solar Fuels and Environmental Remediation | 1.26 | 2025-06-25 | 7 | Band gap engineering; Carbonaceous materials; CO<sub>2</sub> reduction; Photocatalytic water splitting; Redox reaction; SnS nanosheet | English | Final | 2020 | 10.1016/b978-0-12-817836-2.00007-7 | 바로가기 | 바로가기 | ||||||||||||||||||||
| ○ | Article | Ultra Sensitive Detection of H2 in ZnO QD-based Sensors | Interest and demand for hydrogen sensors are increasing in the field of H2 leakage detection during storage/transport/use and detection of H2 dissolved in transformer oil for safety issues as well as in the field of breath analysis for non-invasively diagnosing a number of disease states for a healthy life. In this study, various ZnO-based sensors were synthesized by controlling the reduction in crystallite size, decoration of Pt nanoparticles, doping of electron donating atoms, and doping of various atoms with different ionic radii. The sensing response of the various prepared ZnO-based nanoparticles and quantum dots (QDs) for 10 ppm H2 was investigated. Among the samples, the smallest-sized (3.5 nm) In3+-doped ZnO QDs showed the best sensing response, which is superior to those in previously reported hydrogen sensors based on semiconducting metal oxides. The higher sensing response of In-doped ZnO QDs is attributed to the synergic effects of the increased number of oxygen vacancies, higher optical band gap, and larger specific surface area. © 2020, Korean Sensors Society.

| ○ | Article | Unreported post-harvest disease of apples caused by plenodomus collinsoniae in korea | This study was conducted to isolate and identify the fungal pathogen caused unreported post-harvest disease on apples (cv. Fuji) fruit in Korea. The disease symptoms on apples appeared as irregular, light to dark brown, slightly sunken spots. The three fungal strains were isolated from infected tissues of apple fruits and their cultural and morphological characteristics were completely consistent with those of Plenodomus collinsoniae. The phylogenetic analysis using the internal transcribed spacer (ITS) regions, beta-tubulin (TUB ), and the second largest subunit of RNA polymerase II (RPB 2) sequences revealed the closest relationship of the isolates with Plenodomus collinsoniae at the species level. The pathogenicity test showed the same dark brown spots on Fuji apple cultivar. Therefore, P. collinsoniae is a newly reported fungal agent causing post-harvest disease on apples in Korea. © 2020 Korean Society of Mycology.

| ○ | ○ | Proceedings Paper | Unsupervised Adversarial Learning for Dynamic Background Modeling | Dynamic Background Modeling (DBM) is a crucial task in many computer vision based applications such as human activity analysis, traffic monitoring, surveillance, and security. DBM is extremely challenging in scenarios like illumination changes, camouflage, intermittent object motion or shadows. In this study, we proposed an end-to-end framework based on Generative Adversarial Network, which can generate dynamic background information for the task of DBM in an unsupervised manner. Our proposed model can handle the problem of DBM in the presence of the challenges mentioned above by generating data similar to the desired information. The primary aim of our proposed model during training is to learn all the dynamic changes in a scene-specific background information. While, during testing, inverse mapping of data to latent space representation in our model generates dynamic backgrounds similar to test data. The comparative analysis of our proposed model upon experimental evaluations on SBM.net and SBI benchmark datasets has outperformed eight existing methods for DBM in many challenging scenarios. | Sultana, Maryam; Mahmood, Arif; Bouwmans, Thierry; Jung, Soon Ki | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea; Informat Technol Univ ITU, Dept Comp Sci, Lahore, Pakistan; Univ deLaRochelle, Lab MIA, Larochelle, France | ; BOUWMANS, Thierry/H-7041-2017; Mahmood, Arif/R-7949-2019; Jung, Soon Ki/P-7687-2018 | 57196402440; 55636036300; 25631832300; 57226791905 | maryam@vr.knu.ac.kr;arif.mahmood@itu.edu.pk;thierry.bouwmans@univ-lr.fr;skjung@knu.ac.kr; | FRONTIERS OF COMPUTER VISION | 1865-0929 | 1865-0937 | 1212 | 2.52 | 2025-06-25 | 10 | 8 | Background initialization; Generative Adversarial Networks; Unsupervised learning | ROBUST-PCA; INITIALIZATION; NETWORK | Background initialization; Generative Adversarial Networks; Unsupervised learning | Computer vision; Adversarial learning; Adversarial networks; Background information; Comparative analysis; Experimental evaluation; Human activity analysis; Illumination changes; Vision-based applications; Inverse problems | English | 2020 | 2020 | 10.1007/978-981-15-4818-5_19 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Proceedings Paper | User Insensible Sliding Firmware Update Technique for Flash-Area/Time-Cost Reduction toward Low-Power Embedded Software Replacement | In applications where firmware updates are frequent, such as edge devices in the Internet of Things (IoT) networks with embedded systems, the update process is considered a significant role in improving device performance. This paper proposed a user insensible sliding firmware update technique based on a function block that reduces flash memory usage by handling only part of function blocks instead of the entire firmware, and device's pause time by allowing the user to use the device between function block updates. The proposed technique was evaluated using the target board with the actual ARM core. As a result, the flash memory usage overhead was reduced by 63.64%, paused minimum time was reduced by 79.98% at once update process, and energy consumption reduced by 78.78%. We show that user insensible sliding firmware update has great potential for implementing IoT networks that change behavior quickly by being aware of the environment. | Kwon, Jisu; Seok, Moon Gi; Park, Daejin | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Nanyang Technol Univ, Sch Comp Sci & Engn, Singapore 639798, Singapore | 57215531728; 36683242700; 55463943600 | kwonjisu215@gmail.com;moongi.seok@ntu.edu.sg;boltanut@knu.ac.kr; | 2020 IEEE COOL CHIPS 23: IEEE SYMPOSIUM ON LOW-POWER AND HIGH-SPEED CHIPS AND SYSTEMS | 2473-4683 | 0.9 | 2025-06-25 | 7 | 6 | embedded system; flash memory; firmware update; memory map; linker script | embedded system; firmware update; flash memory; linker script; memory map | Embedded systems; Energy utilization; Firmware; Flash memory; Device performance; Firmware updates; Flash area; Function Block; Internet of thing (IOT); IOT networks; Minimum time; Software replacement; Internet of things | English | 2020 | 2020 | 10.1109/coolchips49199.2020.9097638 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | ○ | Article | Using Digital Technology to Address Confirmability and Scalability in Thematic Analysis of Participant-Provided Data | This article presents a technique for analyzing large-scale qualitative data to address considerations for scalability and confirmability in thematic analysis of participant-provided data. A network approach provides a consistent means of coding that scales with the size of the dataset and is verifiable using standardized methods. This form of data analysis can be used with smaller data sources including interview transcripts as well as large data sources such as open-ended survey responses. A constructivist (inductive) approach is maintained and needed, however, to aid in interpretation of latent constructs. In this article, we provide both a conceptual overview of the co-word analysis method and a practical example. | Chung, Chung Joo; Biddix, J.

| ○ | ○ | Proceedings Paper | Using near-infrared spectroscopy to monitor spinal cord oxygenation in the injured spinal cord | Introduction: Current clinical guidelines recommend augmenting the mean arterial pressure (MAP) in acute spinal cord injury (SCI) patients to increase perfusion and oxygen delivery to the spinal cord, and potentially improve neurologic function. However, it is difficult for clinicians to hemodynamically manage acute SCI patients without real-time physiologic information about the effect of MAP augmentation within the injured cord. In this study, we investigated the utilization of a customized optical sensor, based on near-infrared spectroscopy (NIRS), to non-invasively monitor spinal cord oxygenation during the first week post-injury in a porcine model. Methods: Six Yucatan mini-pigs received a weight-drop T10 contusion-compression injury. A multi-wavelength NIRS system with a custom-made miniaturized sensor was placed directly onto the dura. The spinal cord tissue oxygenation index (TOI) and concentrations of oxygenated, deoxygenated, and total hemoglobin were monitored before and after SCI. To validate the NIRS measures, invasive intraparenchymal (IP) combined PO2/blood flow sensors were inserted into the spinal cord adjacent to the NIRS sensor. Episodes of MAP alteration and hypoxia were performed acutely after injury, 2 days post-injury, and 7 days post-injury to simulate the types of hemodynamic changes SCI patients experience post-injury. Results: Non-invasive NIRS monitoring identified changes in spinal cord oxygenation levels during the MAP alterations. Changes of TOI followed similar patterns of IP-derived oxygenation changes. Conclusion: Our novel NIRS sensor is feasible as a non-invasive technique to monitor real-time changes in spinal cord oxygenation 7 days post-injury in a porcine model of SCI. | Cheung, A.; Tu, L.; Manouchehri, N.; Kim, K.

| ○ | Conference paper | Utilization of Postural Transitions in Sensor-based Human Activity Recognition | Sensor-based human activity recognition (HAR) has gained tremendous attention due to numerous applications that aim to monitor the movement and behaviour of humans. However, the occurrence of transitions between activities gives rise to many problems in HAR as they can affect the performance of the recognition system by causing fluctuations in the prediction. This paper proposes an HAR system using groups of similar postural transitions, discrete wavelet transform (DWT) and bidirectional long short-term memory (BiLSTM) to deal with the postural transitions, thereby improving the accuracy of the system. In this system, the transitions which have similar patterns are grouped into same groups, after that the essential features are extracted by using DWT before being fed into the BiLSTM network for activity classification task. Our experiment results indicate that the proposed model achieves competitive performance compared to a non-transition model. © 2020 IEEE. | Thu, Nguyen Thi Hoai; Han, Dong Seog | School of Electronics Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, Kyungpook National University, Daegu, South Korea | 57216620557; 7403219442 | 2020 International Conference on Artificial Intelligence in Information and Communication, ICAIIC 2020 | 1.48 | 2025-06-25 | 17 | bidirectional long short-term memory; discrete wavelet transform; Human activity recognition; transitions | Artificial intelligence; Pattern recognition; Signal reconstruction; Activity classifications; Competitive performance; Essential features; Human activity recognition; Recognition systems; Similar pattern; Transition model; Discrete wavelet transforms | English | Final | 2020 | 10.1109/icaiic48513.2020.9065250 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | ○ | Article | Variation in clinical usefulness of biomarkers of acute kidney injury in young children undergoing cardiac surgery | Background: Acute kidney injury (AKI) is one of the most significant postoperative complications of pediatric cardiac surgery. Because serum creatinine has limitations as a diagnostic marker of AKI, new biomarkers including neutrophil gelatinaseassociated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18)are being evaluated to overcome these limitations anddetect AKI at an early stage after cardiac surgery. Purpose: This study aimed to investigate the clinical usefulness of these biomarkers in young children. Methods: Thirty patients with congenital heart diseases who underwent cardiac surgery using cardiopulmonary bypass (CPB) were selected, and their urine and blood samples were collected at baseline and 6, 24, and 48 hours after surgery. Serum creatinine and blood urea nitrogen levels as well as NGAL, KIM-1, and IL-18 levels in urine samples were measured, and clinical parameters were evaluated. Results: Of the 30 patients, 12 developed AKI within 48 hours after cardiac surgery. In the AKI group, 8 of 12 (66.6%) met AKI criteria after 24 hours, and urine KIM-1/creatinine (Cr) level (with adjustment of urine creatinine) peaked at 24 hours with significant difference from baseline level. Additionally, urine KIM-1/Cr level in the AKI group was significantly higher than in the non-AKI group at 6 hours. However, urine NGAL/Cr and IL-18/Cr levels showed no specific trend with time for 48 hours after cardiac surgery. Conclusion: It is suggested that urine KIM-1/Cr concentration could be considered a good biomarker for early AKI prediction after open cardiac surgery using CPB in young children with congenital heart diseases. | Baek, Hee Sun; Lee, Youngok; Jang, Hea Min; Cho, Joonyong; Hyun, Myung Chul; Kim, Yeo Hyang; Hwang, Su-Kyeong; Cho, Min Hyun | Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Thorac & Cardiovasc Surg, Daegu, South Korea | 56689379700; 36461117600; 57216601178; 57195637434; 8704315000; 57032023800; 37761570400; 7401727726 | chomh@knu.ac.kr; | CLINICAL AND EXPERIMENTAL PEDIATRICS | 2713-4148 | 63 | 4 | 0.66 | 2025-06-25 | 7 | 8 | Biomarkers; Acute kidney injury; Cardiac surgery; Child | URINARY BIOMARKERS; DIAGNOSIS; OUTCOMES; AKI | Acute kidney injury; Biomarkers; Cardiac surgery; Child | biological marker; interleukin 18; kidney injury molecule 1; neutrophil gelatinase associated lipocalin; acute kidney failure; Article; blood level; blood sampling; cardiopulmonary bypass; child; clinical article; clinical outcome; clinical practice; comparative study; congenital heart disease; controlled study; creatinine blood level; creatinine urine level; early cancer diagnosis; enzyme linked immunosorbent assay; female; heart surgery; human; male; mean arterial pressure; urea blood level; urea nitrogen blood level; urine sampling | English | 2020 | 2020-04 | 10.3345/cep.2019.00913 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Proceedings Paper | Vehicular Adhoc Networks Protocol to Avoid Traffic Signal Delay | Traffic congestion, collision, and long delay on a traffic signal, etc., are prominent issues in today's transportation system. To address these issues, literature constitutes different traffic flow models to analyze road conditions. In this context, this paper proposed an optimum scheme called Traffic Signal Delay Avoidance Protocol (TSDAP) based on frequent beacon messages, which aim to estimate speed for vehicles to avoid a long wait on traffic signals. Secondly, the dynamic speed assistance to the driver is another feature of TSDAP. The dynamic speed assistance feature enabled TADAP to avoid a collision. Our simulation results show that the proposed scheme significantly outperforms in terms of speed recommendation for collision and delay avoidance. | Diyan, Muhammad; Silva, Bhagya Nathali; Han, Jihun; Lee, Kyuchang; Cao Zhenbo; Han, Kijun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | Diyan, Muhammad/AAM-5848-2021; Silva, Bhagya/AAW-1014-2021 | 26028317800; 57192304387; 8644262600; 57213678506; 57225835510; 7402963670 | mdiyan@netopia.knu.ac.kr;nathalis@netopia.knu.ac.kr;jhhan@netopia.knu.ac.kr;skynsoul@gmail.com;zbcao@netopia.knu.ac.kr;kjhan@knu.ac.kr; | 2020 IEEE WIRELESS COMMUNICATIONS AND NETWORKING CONFERENCE WORKSHOPS (WCNCW) | 2167-8189 | 0 | 2025-06-25 | 0 | 0 | Congestion detection; Delay avoidance; intelligent transportation system; speed assistance; traffic flow model | Congestion detection; Delay avoidance; intelligent transportation system; speed assistance; traffic flow model | Traffic congestion; Vehicular ad hoc networks; Dynamic speed; Long delays; Road condition; Traffic flow models; Traffic signal delays; Transportation system; Traffic signals | English | 2020 | 2020 | 10.1109/wcncw48565.2020.9124749 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Article | Viscozyme l aided flavonoid extraction and identification of quercetin from Saururus chinensis (Lour.) Baill | In order to enhance the extraction efficiency of flavonoid from Saururus chinensis, carbohydrate-hydrolyzing enzyme Viscozyme L aided extraction techniques have been studied. Then flavonoid composition, as well as quercetin, were also identified using UV/Vis, HPLC/MS, and1H-NMR. The results showed that favorable extraction conditions were Viscozyme L concentration of 0.25 mg/g, pH 4.2, reaction at 45oC for 12 h. Under the favorable extraction condition, total flavonoid yield (37.9 mg/g) and quercetin yield (0.86 mg/g) increased by about 2.0 and 9.6 times, respectively, compared to control group. Interestingly, as a significant flavonoid of S. chinensis, flavonoid glycones rutin was hydrolyzed to aglycones quercetin by Viscozyme L. These findings provide scientific and theoretical support for the development quercetin-rich products, which was quickly absorbed by the human body than rutin. © The Korean Society for Applied Biological Chemistry 2020. | Zheng, Hu-Zhe; Kwon, Sun-Young; Chung, Shin-Kyo | Department of Health Science, Jiangsu Food & Pharmaceutical Science College, Huai’an, 223003, China, School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Biotechnology, Kyungpook National University, Daegu, 41566, South Korea | 35217210000; 57219208454; 7404292790 | huzhezheng@163.com; | Journal of Applied Biological Chemistry | 1976-0442 | 63 | 3 | 0.14 | 2025-06-25 | 2 | Flavonoid; Identify; Quercetin; Saururus chinensis (Lour.)

| ○ | ○ | Proceedings Paper | Vocoder-free End-to-End Voice Conversion with Transformer Network | Mel-frequency filter bank (MFB) based approaches have the advantage of higher learning speeds compared to using the raw spectrum due to a smaller number of features. However, speech generators with the MFB approach require an additional computationally expensive vocoder for the training process. The pre- and post-processing needed by the MFB and the vocoder is not essential to convert human voices, because it is possible to use only the raw spectrum to generate different style of voices with clear pronunciation. In this paper, we introduce a vocoder-free end-to-end voice conversion method using a transformer network to alleviate the computational burden from additional pre- and post-processing. Our transformer-based architecture, which does not have any CNN or RNN layers, has shown the benefit of learning fast while solving the limitation of sequential computation of the conventional RNN. For this reason, our model is a fast and effective approach to convert realistic voices using raw spectra in a parallel manner to generate different style of voices with clear pronunciation. Furthermore, we can get an adapted MFB for speech recognition by multiplying the converted magnitude with the phase information, and therefore our conversion model is also suitable for speaker adaptation. We perform our voice conversion experiments on TIDIGITS-dataset using the naturalness, similarity, and clarity with Mean Opinion Score as metrics.(1) | Kim, June-Woo; Jung, Ho-Young; Lee, Minho | Kyungpook Natl Univ, Dept Sensor & Display Engn, Daegu, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Lee, Min-Ho/ABE-5735-2021 | 57219550643; 57198760619; 57191730119 | kaen2891@gmail.com;hoyjung@knu.ac.kr;mholee@gmail.com; | 2020 INTERNATIONAL JOINT CONFERENCE ON NEURAL NETWORKS (IJCNN) | 2161-4393 | 0.32 | 2025-06-25 | 4 | 5 | voice conversion; vocoder-free; transformer; spectrum; phase | phase; spectrum; transformer; vocoder-free; voice conversion | Speech recognition; Vocoders; Computational burden; Conversion model; Effective approaches; Mean opinion scores; Phase information; Sequential computations; Speaker adaptation; Training process; Recurrent neural networks | English | 2020 | 2020 | 10.1109/ijcnn48605.2020.9207653 | 바로가기 | 바로가기 | 바로가기 |
