| ○ | ○ | Article | Theoretical DFT Investigation of Structure and Electronic Properties of η⁵-Cyclopentadienyl Half-Sandwich Organochalcogenide Complexes | For the first time, an extensive theoretical comparative study of the electronic structure and spectra of the & eta;(5)-cyclopentadienyl half-sandwich [(Cp)(EPh3)], E = Se, Te) organochalcogenides was carried out using direct space electronic structure calculations within hybrid, meta, and meta-hybrid DFT GGA functionals coupled with double-& zeta; polarized 6-31G* and correlation-consistent triple-zeta cc-pVTZ-pp basis sets. The absence of covalent bonding between the cyclopentadienyl (Cp) ligands and Te/Se coordination centers was revealed. It was found that the chalcogens are partially positively charged and Cp ligands are partially negatively charged, which directly indicates a visible ionic contribution to Te/Se-Cp chemical bonding. Simulated UV-Vis absorption spectra show that all complexes have a UV-active nature, with a considerable shift in their visible light absorption due to the addition of methyl groups. The highest occupied molecular orbitals exhibit & pi;-bonding between the Te/Se centers and Cp rings, although the majority of the orbital density is localized inside the Cp & pi;-system. The presence of the chalcogen atoms and the extension of & pi;-bonds across the chalcogen-ligand interface make the species promising for advanced photovoltaic and light-emitting applications. | Oyeniyi, G.

| ○ | Article | Therapeutic Use of Posaconazole for Cutaneous Purpureocillium lilacinum Infection Refractory to Itraconazole | Purpureocillium lilacinum is a saprophytic fungus with a ubiquitous environmental distribution. Unfortunately, no standard treatment has yet been established for cutaneous P. lilacinum infections. Based on the in vitro antifungal susceptibility test, posaconazole has been considered an effective treatment option. We herein present a case involving a 72-year-old woman who visited our clinic due to a peripherally spreading, well-demarcated, asymptomatic, scaly, and erythematous patch on her forehead that had persisted for 4 months. She had been diagnosed with cutaneous P. lilacinum infection and had been treated with itraconazole (200 mg/day). However, the lesion recurred in the same area. Histopathological findings revealed suppurative granulomatous dermatitis with fungal elements. Fungal culture confirmed P. lilacinum regrowth. Posaconazole was selected to treat the recurrence of P. lilacinum infection. After 10 weeks of treatment, the lesion decreased dramatically without any adverse drug events. We recommend posaconazole as a treatment option for P. lilacinum infection refractory to itraconazole. Copyright@2023 by The Korean Society for Medical Mycology.

| ○ | Conference paper | Thermal comfort prediction considering thermal adaptation based on facial temperature using thermal images and subjective indexes | The aim of this study is to predict thermal comfort based on a subjective evaluation index of occupants and thermal imaging data, which are physiological signals, while considering thermal adaptation. This study was conducted in an office in the winter, and three subjective evaluation indexes were used. Air temperature data was obtained using a specific equipment, and the facial temperature was recorded using a thermal imaging camera. Based on analysis, thermal adaptation yielded different results at the same facial temperature. In previous studies, a facial temperature of 33 °C before thermal adaptation signified discomfort. However, the same facial temperature of 33 °C after thermal adaptation signified comfort. This implies that simple indexes and physiological signals based on thermal imaging are insufficient to predict the subjective thermal sensation of occupants. Therefore, accuracy of thermal comfort prediction can be improved significantly by considering thermal adaptation using the existing subjective evaluation indexes as well as by considering the results of studies pertaining to facial temperature. © The Authors, published by EDP Sciences, 2023. | Kim, Sung-Kyung; Ryu, Ji-Hye; Hong, Won-Hwa | Convergence Institute of Construction, Environmental and Energy Engineering, Kyungpook National University, South Korea; Convergence Institute of Construction, Environmental and Energy Engineering, Kyungpook National University, South Korea; School of Architectural, Civil, Environmental and Energy Engineering, Kyungpook National University, South Korea | 57196459261; 56192651000; 7401527968 | ryou0407@knu.ac.kr; | E3S Web of Conferences | 2555-0403 | 396 | 0.77 | 2025-06-25 | 1 | English | Final | 2023 | 10.1051/e3sconf/202339601109 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Book chapter | Thermal conductivity enhancement of phase change materials | Thermally efficient latent heat storage systems require fast thermal charging and discharging rates. However, the low thermal conductivity (0.2W/mK) of the phase change materials (PCMs) obstructs thermal transport within the energy storage system. Therefore, the heat transfer rate within the PCMs has yet to be augmented to make it practical and efficient. The interfacial site of phase change, heat transfer rate, temperature distribution within the PCM, system heat capacity, and the nature of the dominant heat transfer mode are all heat transfer issues with PCMs (conduction or convection). This chapter provides a deep insight into the recent techniques for the augmentation of the effective thermal conductivity of the PCMs. Chemical alteration of the PCMs, metallic and carbon-based nanoparticles, and porous materials simultaneously enhance their thermal conductivity. Furthermore, the effect of thermally enhanced additives on the latent heat of the PCMs has also been analyzed along with the thermal charging and discharging time, melting rate of the PCMs, and temperature gradient. Additionally, thermal conductivity measurement techniques have been presented numerically and experimentally. © 2023 Elsevier Inc.

| ○ | Book chapter | Tidal coastal wetlands for wastewater management | Tackling the global water scarcity problem and inadequate clean water supply, caused majorly by various upsurging anthropogenic factors, must be addressed decisively by establishing a sustainable framework for effective wastewater treatment and management. The tidal coastal wetland is a cost-effective and sustainable treatment ecosystem that is valuable in managing secondary treated effluents, as documented. It also ensures the delivery of safe water into the environment compared to conventional treatment methods. They have been labelled as one of the most productive ecosystems with high economic importance. However, factors such as climate change, sea-level rise, nutrient inputs and sediment delivery have impacted negatively on this wetland hence resulting in continuous degradation and loss. Therefore, this chapter first provides an overview of the various forms of tidal coastal wetlands and their economic importance. Next, case and modelling studies supported some key information on the essence of tidal coastal wetlands in the effective wastewater management process. © 2023 Elsevier Inc. | Lasisi, Kayode Hassan; Ajibade, Fidelis Odedishemi; Idowu, Temitope Ezekiel; Ajibade, Temitope Fausat; Adelodun, Bashir; Ojo, Adedamola Oluwafemi; Fadugba, Olaolu George; Olanrewaju, Olawale Olugbenga; Adewumi, James Rotimi | Department of Civil and Environmental Engineering, Federal University of Technology, Akure, Nigeria, Institute of Urban Environment, Chinese Academy of Sciences, Xiamen, China, University of Chinese Academy of Sciences, Beijing, China; Department of Civil and Environmental Engineering, Federal University of Technology, Akure, Nigeria, University of Chinese Academy of Sciences, Beijing, China, CAS Key Lab of Environmental Biotechnology, Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, China; Center for Applied Coastal Research, University of Delaware, Newark, DE, United States; Department of Civil and Environmental Engineering, Federal University of Technology, Akure, Nigeria, Institute of Urban Environment, Chinese Academy of Sciences, Xiamen, China, University of Chinese Academy of Sciences, Beijing, China; Department of Agricultural and Biosystems Engineering, University of Ilorin, Ilorin, Nigeria, Department of Agricultural Civil Engineering, Kyungpook National University, Daegu, South Korea; Department of Civil Engineering, Yaba College of Technology, Lagos, Nigeria; Department of Civil and Environmental Engineering, Federal University of Technology, Akure, Nigeria; Department of Agricultural and Environmental Engineering, Federal University of Technology, Akure, Nigeria; Department of Civil and Environmental Engineering, Federal University of Technology, Akure, Nigeria | 57208598946; 57190341647; 57194585450; 57208594522; 57193774482; 57218165256; 57212380624; 57212572267; 26031266400 | foajibade@futa.edu.ng; | Advances in Chemical Pollution, Environmental Management and Protection | 2468-9289 | 9 | 0 | 2025-06-25 | 0 | Ecosystem services; Tidal coastal wetland; Wastewater management; Wastewater treatment | English | Final | 2023 | 10.1016/bs.apmp.2022.11.002 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Article | To adopt rooftop solar or not along with electric vehicles? Exploring the factors influencing Co-adoption decisions among electric vehicle owners in California | Co-adoption of electric vehicles (EV) and photovoltaic (PV) technology can boost the environmental benefits of the two "green" technologies for society as well as the cost-saving benefits for co-adopters. This study contributes to the literature on this topic by investigating the factors influencing the co-adoption decision among EV owners in California, a leading market for the two complementary technologies. Analyzing data from a cohort survey of EV owners in California, using statistical analyses and logistic regression, we find that there are differences between co-adopters and EV-only households in terms of sociodemographic characteristics like dwelling type, income, and household size; economic factors like residential electricity rate plan; EV type, and electric range; and access to charging capabilities at home and work. Most of these factors also influence the intention of current only EV-owners to adopt PV or not in the future. These findings raise important policy questions regarding incentive needs to improve affordability and address equity issues as well as the need for pricing mechanisms at the utility level and by charging service providers to encourage co-adoption among EV owners. | Chakraborty, Debapriya; Lee, Jae Hyun; Chakraborty, Amrita; Tal, Gil | Univ Calif Davis, Inst Transportat Studies, Davis, CA 95616 USA; Kyungpook Natl Univ, Dept Geog, 80 Daehak Ro, Bukgu, Daegu, South Korea; Univ Calif Davis, Inst Transportat Studies, Elect Vehicle Res Ctr, Davis, CA USA | Tal, Gil/A-7392-2012; Lee, Jae/ABH-9059-2020 | 57225755012; 57189870403; 58537563500; 26039509400 | dchakraborty@ucdavis.edu; | ELECTRICITY JOURNAL | 1040-6190 | 1873-6874 | 36 | 7 | 1.33 | 2025-06-25 | 8 | 8 | Solar photovoltaic; Electric Vehicles; Co-adoption | INCENTIVES; HETEROGENEITY | Co-adoption; Electric Vehicles; Solar photovoltaic | Costs; Economic analysis; Electric vehicles; Environmental technology; Solar power generation; Adoption decision; California; Co-adoption; Cost saving; Environmental benefits; Green technology; Logistics regressions; Photovoltaic technology; Solar photovoltaics; Vehicle technology; Housing | English | 2023 | 2023 (AUG-SEP) | 10.1016/j.tej.2023.107315 | 바로가기 | 바로가기 | 바로가기 | ||||||||

| ○ | Review | Tolvaptan: a possible preemptive treatment option in children with autosomal dominant polycystic kidney disease? | Tolvaptan is a highly selective vasopressin receptor 2 antagonist that regulates cyclic adenosine monophosphate levels to inhibit both epithelial cell proliferation and chloride ion excretion, two mechanisms known to induce cyst expansion in autosomal dominant polycystic kidney disease (ADPKD). Tolvaptan is currently the preferred treatment of rapidly progressive disease ADPKD in adult patients; however, since cyst formation in ADPKD begins early in life, (frequently in utero), and significant disease progression with cyst expansion occurs in the first decade, tolvaptan may be advantageous as a preemptive treatment in children with ADPKD. Tolvaptan has already been used to successfully treat refractory edema or hyponatremia in children; this literature review provides insight into the biochemical basis of its action to contextualize its use in the pediatric population. © 2023 Korean Society of Pediatric Nephrology. | Beak, Hee Sun; Cho, Min Hyun | Department of Pediatrics, Yeungnam University College of Medicine, Daegu, South Korea; Department of Pediatrics, School of Medicine, Kyungpook National University, Daegu, South Korea | 59324296200; 7401727726 | chomh@knu.ac.kr; | Childhood Kidney Diseases | 2384-0242 | 27 | 2 | 0.13 | 2025-06-25 | 1 | Child; Polycystic kidney, autosomal dominant; Tolvaptan | English | Final | 2023 | 10.3339/ckd.23.021 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Conference paper | TorchAxf: Enabling Rapid Simulation of Approximate DNN Models Using GPU-Based Floating-Point Computing Framework | This paper presents an approximate floating-point computing framework TorctiAxf1 that enables fast simulation of various approximate deep neural network (DNN) models, including spiking neural networks (SNNs), using various types of approximate adders and multipliers. Additionally, it supports the standard reduced precision floating-point formats, such as bfloat16, and any user-customized precision representation. TorchAxf leverages GPU acceleration to expedite approximate DNN training and inference running on the PyTorch framework. Any arbitrary approximate arithmetic algorithm with C/C++ behavioral models can be readily integrated with TorchAxf to emulate approximate DNN accelerators. Through extensive experiments, we reveal an appropriate degree of the floating-point arithmetic that can be approximated for DNN models without any significant accuracy loss. We also show that approximate-aware re-training can recover errors and refine pre-trained DNN models under reduced precision formats. Besides, TorchAxf running on GPU enables the simulation time of complex DNN models using approximate arithmetic to reduce up to 43.17× compared to the baseline optimized CPU implementation. © 2023 IEEE. | Kwak, Myeongjin; Kim, Jeonggeun; Kim, Yongtae | School of Computer Science and Engineering, Kyungpook National University, Daegu, South Korea; School of Computer Science and Engineering, Kyungpook National University, Daegu, South Korea; School of Computer Science and Engineering, Kyungpook National University, Daegu, South Korea | 57222516282; 57040520600; 55699627900 | yongtae@knu.ac.kr; | Proceedings - IEEE Computer Society's Annual International Symposium on Modeling, Analysis, and Simulation of Computer and Telecommunications Systems, MASCOTS | 1526-7539 | 1.04 | 2025-06-25 | 2 | accelerator; Approximate computing; deep neural network (DNN); fast simulation; floating-point; GPU; PyTorch; spiking neural network (SNN) | Deep neural networks; Digital arithmetic; Approximate computing; Computing frameworks; Deep neural network; Fast simulation; Floating points; Neural network model; Neural-networks; Pytorch; Reduced precision; Spiking neural network; Graphics processing unit | English | Final | 2023 | 10.1109/mascots59514.2023.10387653 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Book chapter | Torsional Warping and Torsional Distortion as Fundamental Deformable Section Modes | As can be observed from the T-joint problem considered in Fig. 1.8, the effects of section deformations, i.e., torsional warping and torsional distortion, on the overall stiffness of a thin-walled beam are significant due to their coupling behavior with torsional rotation when the beam is subjected to a torsional load or a more general load. The torsional warping and torsional distortion modes involve deformation of the cross-section of a beam, but they will be treated as modes belonging to the fundamental mode set in the HoBT; these two modes as well as the six rigid-body section modes are treated as fundamental modes in this book. As shall be shown later, none of the higher-order section-deformable modes, such as torsional warping and torsional distortion modes (see Table 1.1), produce net non-zero resultant force or moment. Therefore, the stress and displacement of these modes should decay along the axis of a beam under a static load. However, their decay rates can be quite different depending on the mode type and order. For instance, the stress and displacement of torsional warping and torsional distortion modes can survive even several times longer than the cross-sectional width, while those of other higher-order modes decay rapidly. It should also be noted that due to geometric characteristics, the effects of the torsional warping mode for open-section beams generally survive longer than those for closed-sectioned beams. Because the warping effect in open-section beams is generally significant, a structural analysis of such beams using field variables having non-zero resultant forces and moments only produces unacceptably inaccurate results. For this reason, Vlasov (1961) mostly focused his analyses on the torsional warping mode in open-section beams in his beam theory. In the case of closed thin-walled cross-sections, the torsional distortion mode can be induced by torsional warping (Kim and Kim 1999a, b, 2000, 2003; Choi and Kim 2021; Camotim et al. 2010; Goncalves et al. 2010; Yu et al. 2012). Therefore, both torsional warping and torsional distortion modes should be used simultaneously to yield accurate results. (Note that torsion warping is generally coupled with torsion in thin-walled closed-section beams.) © 2023, Springer Nature Singapore Pte Ltd. | Kim, Yoon Young; Jang, Gang-Won; Choi, Soomin | Department of Mechanical Engineering, Seoul National University, Seoul, South Korea; Department of Mechanical Engineering, Sejong University, Seoul, South Korea; School of Mechanical Engineering, Kyungpook National University, Daegu, South Korea | 36062771200; 7102646127; 56124305600 | yykim@snu.ac.kr; | Solid Mechanics and its Applications | 0925-0042 | 257 | 0 | 2025-06-25 | 0 | Decay (organic); Thin walled structures; Fundamental modes; Open section; Resultant forces; Section deformations; Stress and displacements; T joints; T-joints; Thin-walled; Torsional warping; Warping modes; Torsional stress | English | Final | 2023 | 10.1007/978-981-19-7772-5_2 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Proceedings Paper | Towards Better Visualizing the Decision Basis of Networks via Unfold and Conquer Attribution Guidance | Revealing the transparency of Deep Neural Networks (DNNs) has been widely studied to describe the decision mechanisms of network inner structures. In this paper, we propose a novel post-hoc framework, Unfold and Conquer Attribution Guidance (UCAG), which enhances the explainability of the network decision by spatially scrutinizing the input features with respect to the model confidence. Addressing the phenomenon of missing detailed descriptions, UCAG sequentially complies with the confidence of slices of the image, leading to providing an abundant and clear interpretation. Therefore, it is possible to enhance the representation ability of explanation by preserving the detailed descriptions of assistant input features, which are commonly overwhelmed by the main meaningful regions. We conduct numerous evaluations to validate the performance in several metrics: i) deletion and insertion, ii) (energy-based) pointing games, and iii) positive and negative density maps. Experimental results, including qualitative comparisons, demonstrate that our method outperforms the existing methods with the nature of clear and detailed explanations and applicability. | Hong, Jung-Ho; Nam, Woo-Jeoung; Jeon, Kyu-Sung; Lee, Seong-Whan | Korea Univ, Dept Artificial Intelligence, Seoul, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | jungho-hong@korea.ac.kr;nwj0612@knu.ac.kr;ksjeon@korea.ac.kr;sw.lee@korea.ac.kr; | THIRTY-SEVENTH AAAI CONFERENCE ON ARTIFICIAL INTELLIGENCE, VOL 37 NO 7 | 2159-5399 | 2374-3468 | 2 | DEEP NEURAL-NETWORKS; ACTIVATION MAPS | English | 2023 | 2023 | 바로가기 | ||||||||||||||||||||||

| ○ | ○ | Proceedings Paper | Towards Quantized Stochastic Computing by Leveraging Reduced Precision Binary Numbers through Bit Truncation | Stochastic computing (SC) offers high hardware efficiency and error tolerance but faces challenges, such as the overhead of converting between binary and stochastic forms. This paper introduces a novel quantized SC architecture, significantly reducing stochastic number generator (SNG) hardware complexity. We achieve this by quantizing binary numbers to lower precision using various bit truncation schemes, thereby reducing SNG overhead. Implemented in a 65-nm CMOS process, our proposed quantized SNG reduces area and power by up to 65.5% and 73.0%, respectively, compared to the conventional full-precision SNG. We also demonstrate that our SC schemes have minimal impact on processing quality while greatly improving hardware efficiency, as seen in a digital image processing application. | Lee, Donghui; Kim, Yongtae | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu, South Korea | 57266466900; 55699627900 | thebock12@knu.ac.kr;yongtae@knu.ac.kr; | 2023 IEEE 41ST INTERNATIONAL CONFERENCE ON COMPUTER DESIGN, ICCD | 1063-6404 | 1.66 | 2025-06-25 | 2 | 4 | stochastic computing; quantization; bit truncation; stochastic number generator; comparator | bit truncation; comparator; quantization; stochastic computing; stochastic number generator | Comparator circuits; Efficiency; Image enhancement; Number theory; Random number generation; Stochastic systems; Binary number; Bit truncation; Hardware efficiency; Hardware error; Number generator; Quantisation; Reduced precision; Stochastic computing; Stochastic number generator; Stochastic numbers; Comparators (optical) | English | 2023 | 2023 | 10.1109/iccd58817.2023.00069 | 바로가기 | 바로가기 | 바로가기 | |||||||||||||
| ○ | Article | Transformative Technology Adoption and Firm Productivity: Illusionary Revolution or Guaranteed Innovation? | This study examines the impact of strategic technological innovations (e.g., adoption of fourth industrial revolu-tion (4IR) technologies) on firms’ productivity. To estimate the heterogeneous effects of innovation efforts on firms’ labor productivity, this paper employs a quantile regression model and calculates higher moments of the empirical distributions. This study uses data from 11,654 Korean firms that responded to surveys in 2017 and 2018, comprising 23,308 observations. Our empirical results find that 4IR technology adoption has a sig-nificant impact on labor productivity for firms across all quantiles, while the estimates of 4IR technology adoption coefficient on labor productivity are much larger in upper quantiles. This estimated impact of adopting 4IR technology on labor productivity at the upper quantile differs compared to the estimated impact of another innovation strategy, or internal R&D. Notably, adopting 4IR technology increases the median labor productivity of firms and the kurtosis of its distribution. Thus, firms that adopted 4IR technology show labor productivity gains more consistently than those that did not, with few outliers. © (2023).

| ○ | Conference paper | TransUNet-Lite: A Robust Approach to Cell Nuclei Segmentation | Deep convolutional neural networks have demonstrated superior performance in a variety of vision tasks. For biomedical applications, these methods suffer from problems such as predicting reliable segmentation masks for variable size input images, insufficient data and imbalanced datasets. This paper introduces an efficient and lightweight TransUNet, termed as TransUNet-Lite, that exploits rich feature representations produced by the convolution-based feature extractor, an external attention module instead of conventional self-attention, a fast token selector module, and skip connections from the feature extractor to the decoder to provide lost rich contextual information. The proposed network takes patches as input rather than resized images that fail to care for the original aspect ratio. For the nuclei segmentation task on the 2018 Science Bowl dataset, our TransUNet-Lite outperformed other SOTA networks, with the highest DSC of 93.08% and IoU of 87.95%. The results of our experiments provide insight into the impact of certain network design decisions. By configuring a transformer in a simplistic and efficient manner, it is possible to achieve segmentation quality that is at least equal to SOTA network architectures. © 2023 ACM. | Khan, Muhammad Salman; Ali, Shahzad; Lee, Yu Rim; Kang, Min Kyu; Park, Soo Young; Tak, Won Young; Jung, Soon Ki | School of Computer Science and Engineering, Kyungpook National University, South Korea; School of Computer Science and Engineering, Kyungpook National University, South Korea; Department of Internal Medicine, College of Medicine, Kyungpook National University Hospital, South Korea; Department of Internal Medicine, College of Medicine, Yeungnam University, South Korea; Department of Internal Medicine, College of Medicine, Kyungpook National University Hospital, South Korea; Department of Internal Medicine, College of Medicine, Kyungpook National University Hospital, South Korea; School of Computer Science and Engineering, Kyungpook National University, South Korea | 58725569000; 57709386500; 57194094753; 59142854300; 57191674344; 7004074582; 57226791905 | shahzadaliprince@gmail.com; | ACM International Conference Proceeding Series | 0.91 | 2025-06-25 | 3 | Cell nuclei segmentation; External attention; Lightweight TransUNet; Medical image segmentation; Token selection | Aspect ratio; Convolution; Deep neural networks; Image segmentation; Medical applications; Medical imaging; Biomedical applications; Cell nuclei segmentation; Convolutional neural network; External attention; Feature extractor; Lightweight transunet; Medical image segmentation; Performance; Robust approaches; Token selection; Network architecture | English | Final | 2023 | 10.1145/3608298.3608344 | 바로가기 | 바로가기 |
