This study embarked on a rigorous examination of the factors driving user satisfaction and usage behavior in the context of telehealth applications. Utilizing a well- structured Google Form survey, distributed through an array of social media platforms, including WhatsApp, Discord, Instagram, and Line, the research gathered 251 responses. The purposive sampling technique was employed to ensure that the data captured the experiences of individuals who had actively engaged with telehealth services. One hypothesis, relating to the influence of Online Reviews, was found to be unsupported. This surprising result suggests that, contrary to expectations, the opinions and reviews shared online do not significantly affect users' satisfaction or their behavioral decisions in the context of telehealth applications. This finding highlights the need for a more nuanced understanding of the factors influencing user preferences and choices in this rapidly evolving sector. Conversely, other hypotheses examining factors such as Social Influence, Facilitating Conditions, Perceived Reliability, Price Value, and Purchase Intention were substantiated. The positive influence of these factors on customer usage behavior underscores their significance in shaping user experiences and satisfaction within the telehealth ecosystem. Furthermore, the study posits that facilitating conditions should be closely aligned with technological advancements, as this alignment is conducive to the development of enhanced application features. This insight suggests that telehealth providers should continuously innovate and integrate advanced technologies to ensure that the facilitating conditions meet the ever-evolving needs and expectations of users. © 2023 IEEE.

In this study, aluminum-doped zinc oxide(AZO) thin films were deposited onto a low-temperature polyethylene terephthalate(PET) substrate using DC magnetron sputtering. Deposition parameters included power range of 100-300 W, a working pressure of 15 mTorr, and a substrate temperature of 50 ℃. Post-deposition, flash lamp annealing(FLA) was employed as a rapid thermal processing method with a pulse duration of 1.7 ms and energy density of 7 J·cm-2, aimed at enhancing the film's quality while preserving the temperature-sensitive PET substrate. FLA offers advantages over conventional annealing,including shorter processing times and improved material properties. The structural, optical, and electrical characteristics of the AZO films were assessed using X-ray diffraction, field emission scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, ultraviolet-visible spectroscopy, and Hall effect measurements. The results demonstrated that properties of AZO films varied with deposition and annealing conditions. Films deposited at 200 W and subjected to FLA exhibited superior crystallinity, with average visible light transmittance exceeding 80% and resistivity as low as 0.38 Ω·cm representing 95%improvement in transmittance. Electrical analysis revealed that carrier concentration, mobility, and resistivity were influenced by both sputtering and annealing parameters. These findings underscore the effectiveness of FLA in optimizing AZO thin film properties, highlighting potential in optoelectronics applications.

An Empirical Investigation of the Antecedents and Consequences of Integration Team Ambidexterity in Multiteam systems-Based Projects

引用

IEEE Transactions on engineering management 2024年 71卷 9630-9643页

Firms are increasingly launching large-scale complex projects with the work form of multiteam systems (MTSs) (MTSs-based projects), which requires the management team to be ambidextrous - aligned efficiently with existing demands, whilst being adaptive to the changing environment. However, limited studies have focused on the development of ambidexterity as well as its influences on the success in MTSs-based projects. To address this research gap, this study investigates the antecedents and consequences of ambidexterity of integration teams in MTSs-based projects, using a sequential mixed-method design. A qualitative study via interviews with industrial experts first identified four crucial antecedents of integration team ambidexterity, i.e., shared cognition, information exchange, monitoring, and mutual support. Then, leveraging an emergent team phenomena perspective, we developed a research model and proposed relevant hypotheses. A quantitative study, using multiwave and multisource data collected from 178 MTSs-based enterprise systems implementation projects, was adopted to validate our proposed model. The findings reveal the distinct effects of the four antecedents on integration team alignment and adaptation. In addition, both integration team alignment and adaptation positively influence MTSs-based project effectiveness, while only integration team adaptation facilitates the project team to deal with a high level of requirements instability. © 1988-2012 IEEE.

Backscatter communication and non-orthogonal multiple access (NOMA) represent emerging paradigms in wireless communication, offering promising solutions to boost spectral and energy efficiency for energy-constrained devices in 6G networks. This work introduces a tailored symbiotic radio system designed for Internet of Things (IoT) devices, proposing an innovative framework that integrates backscatter-based IoT devices into power-domain NOMA networks. In this system, the primary base station employs NOMA principles to serve both far and near users simultaneously, while IoT devices equipped with backscattering technology transmit their data over the primary signal. The IoT transmitter not only serves the IoT receiver but also enhances the performance of the far user. The paper thoroughly examines outage probabilities for both NOMA and IoT networks. It delves explicitly into the outage probabilities of IoT receivers, considering both perfect and imperfect direct link interference cancellation. The results demonstrate significant performance improvements over traditional orthogonal multiple-access methods. Furthermore, Monte Carlo simulations are employed to validate the accuracy of the theoretical analysis. © 2024 IEEE.

引用

IEEE Transactions on Semiconductor Manufacturing 2023年第4期36卷 619-628页

作者： Kao, Sheng-Xiang Chien, Chen-Fu International Intercollegiate Ph.D. Program National Tsing Hua University Hsinchu30013 Taiwan Intelligent Manufacturing and Circular Economy Research Center National Tsing Hua University Artificial Intelligence for Intelligent Manufacturing Systems Research Center National Science and Technology Council Department of Industrial Engineering and Engineering Management Hsinchu300044 Taiwan

Little research has been done for artificial intelligence applications of semiconductor backend. This study aims to develop a deep learning based fault diagnosis framework as prognostics and health management (PHM) solutions with a comprehensive analytics process. A linear encoder sensor is employed to measure position, while data preparation is conducted to convert position information into a signal. Then, signal processing is used to extract the features, in which high pass filter is applied to normalize the signal and emphasize the features. High-dimensional features including time domain statistical features, time-frequency domain features obtained by continuous wavelet transform (CWT), and frequency domain features converted by fast Fourier transform (FFT) are extracted to prepare the dataset. An ensemble neural network model that integrates deep neural network (DNN) and convolutional neural network (CNN) is employed to recognize the pattern and diagnose the positioning errors. The accuracy and false alarm rate are considered to support maintenance decisions. An empirical study was conducted in a world leading IC assembly and testing company for validation. The results have shown that the proposed approach can effectively detect inappropriate installation of the bond head in wire bonding equipment for predictive maintenance and cost reduction. © 1988-2012 IEEE.

The aim of the research is to identify, evaluate, and measure the degree of importance of risks associated with healthcare inventory management that may impede the achievement of healthcare inventory objectives. An analytical hierarchy process model (AHP) was proposed to identify and hierarchize healthcare inventory risk factors. Thirteen risk factors were identified from literature review, and the AHP method was applied to rank those factors. The study found that financial risks are more severe than operational risks in healthcare inventory management. The top three risks identified were stock obsolescence, fraud committed by a provider, and insurance company disputes. These risks can have significant negative impacts on healthcare organizations and their ability to provide quality care to patients. Healthcare organizations should be aware of these risks and take steps to mitigate them. Identifying the most serious risks in HC inventory helps decision makers to make more informed data-driven decisions on which interventions are needed and where to invest more to mitigate risks and allocate resources to ensure that their inventory management processes are effective and efficient, thereby improving patient care and outcomes. Additionally, the study helps identify areas where further research is needed. © 2023 Computers and Industrial engineering. All rights reserved.

Significance: Burn injuries represent a global public health problem that kills an estimated 180,000 people annually. Non-fatal burns result in prolonged hospitalization, disfigurement, and disability. The most common, convenient, and widely used method for assessing burn depth is physical or visual examination, but the accuracy of this method is reportedly poor (60% to 75%). Rapid, correct assessment of burn depth is very important for the optimal management and treatment of burn patients. New methods of burn depth assessment that are inexpensive, simple, rapid, non-contact, and non-invasive are therefore needed. Aim: The aim of this study was to propose an approach to visualize the spatial distribution of burn depth using hemoglobin parameters estimated from spectral diffuse reflectance imaging and to demonstrate the feasibility of the proposed approach for differentiating burn depth in a rat model of scald burn injury. Approach: The new approach to creating a spatial map of burn depth was based on canonical discriminant analysis (CDA) of total hemoglobin concentration, tissue oxygen saturation, and methemoglobin saturation as estimated from spectral diffuse reflectance images. Burns of three different degrees of severity were created in rat dorsal skin by 10-s exposure to water maintained at 70°C, 78°C, and 98°C, respectively. Spectral images for dorsal regions were acquired under anesthesia immediately after burn injury and at 24 h, 48 h, and 72 h after injury. Results: Most areas of images in the group with skin exposed to 70°C water and 98° C water were classified as 70°C burn and 98°C burn, respectively. In contrast, no significant difference between areas classified as 78°C burn and 98°C burn from 24 h to 72 h was evident in the group with skin exposed to 78°C water, suggesting that burn depth was heterogeneous. Conclusions: The proposed approach combining diffuse reflectance spectral imaging and CDA appears promising for differentiating 70°C burns from 78°C
