ABSTRACT
Restrictions during the COVID-19 pandemic significantly affected people's opportunities to engage in activities that are meaningful to their lives. In response to these constraints, many people, including older adults, turned to digital technologies as alternative ways to pursue meaningful activities. These technology-mediated activities, however, presented new challenges for older adults' everyday use of technology. In this paper, we investigate how older adults used digital technologies for meaningful activities during COVID-19 restrictions. We conducted in-depth interviews with 40 older adults and analyzed the interview data through the lens of self-determination theory (SDT). Our analysis shows that using digital technologies for meaningful activities can both support and undermine older people's three basic psychological needs for autonomy, competence, and relatedness. We argue that future technologies should be designed to empower older adults' content creation, engagement in personal interests, exploration of technology, effortful communication, and participation in beneficent activities. © 2023 ACM.
ABSTRACT
The COVID-19 (corona virus disease 2019) has caused serious impacts worldwide. Many scholars have done a lot of research on the prevention and control of the epidemic. The diagnosis of COVID-19 by cough is non-contact, low-cost, and easy-access, however, such research is still relatively scarce in China. Mel frequency cepstral coefficients (MFCC) feature can only represent the static sound feature, while the first-order differential MFCC feature can also reflect the dynamic feature of sound. In order to better prevent and treat COVID-19, the paper proposes a dynamic-static dual input deep neural network algorithm for diagnosing COVID-19 by cough. Based on Coswara dataset, cough audio is clipped, MFCC and first-order differential MFCC features are extracted, and a dynamic and static feature dual-input neural network model is trained. The model adopts a statistic pooling layer so that different length of MFCC features can be input. The experiment results show the proposed algorithm can significantly improve the recognition accuracy, recall rate, specificity, and F1-score compared with the existing models. © 2023 Chinese Institute of Electronics.

ABSTRACT
Teleconsultation is a type of medical practice similar to face-to-face consultations, and it allows a health professional to give a consultation remotely through information and communication technologies. In the context of the management of the coronavirus epidemic, the use of teleconsultation practices can facilitate healthcare access and limit the risk of avoidable propagation in medical cabinets. This paper presents the monitoring of international teleconsultation referrals in the era of Covid-19 to facilitate and prevent the suspension of access to care, the most common architecture for teleconsultation, communication technologies and protocols, vital body signals, video transmission, and the conduct of teleconsultation. The aim is to develop a teleconsultation platform to diagnose the patient in real time, transmit data from the remote location to the doctor, and provide a teleconsultation. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
ABSTRACT
The objective of this investigation is to understand how online distance education can contribute to promoting the development of digital skills, in particular, teaching digital skills. Contemporary society increasingly demands the use of digital technologies in the various areas of life, including in the teaching and learning process, even more evident in the pandemic context of COVID-19, which caused the suspension of face-to-face classes worldwide and imposed a new educational model, facilitated by digital technologies and based on online education methodologies, designated as emergency remote teaching. Among the many challenges, teachers had to adapt and reformulate their pedagogical practices and teaching methodologies in a virtual learning environment, often without having fundamental digital skills to promote quality learning. Through a narrative bibliographic review of an exploratory nature and qualitative methodology, studies, programs and models were identified that could be used as a reference to enable training propositions for the development of teaching digital skills, a key factor for pedagogical innovation.
ABSTRACT
Surveys of urban history from ancient times to the present reveal a continuum of collective responses to pandemics ranging from quarantine facilities and monitoring the spread of disease to building new wastewater networks. The contemporary COVID-19 pandemic includes new digital tools and techniques that supplement (and sometimes replace) the existing analogue responses, while raising new ethical issues with respect to privacy. A typology of pandemic responses in cities is created, based on human–building interaction (HBI) principles. This typology can be used to compare and contrast analogue and digital responses relating to distancing, monitoring and sanitising. It provides a summary of a wide range of individual and collective implications of pandemics and demonstrates the indelible connections between pandemics and the built environment. In addition, the typology provides a tool to interpret some of the opportunities and drawbacks of digitalising cities. PRACTICE RELEVANCE The COVID-19 pandemic has demonstrated the enduring co-evolution of cities and disease through history. This study aims to inform future pandemic preparedness by providing a framework for designers, managers and users of public spaces to evaluate the multiple implications of emerging technologies that are integrated within the urban fabric. While the rapid rise of digitalisation to advance urban health agendas continues to raise new questions relating to individual and civic freedoms, HBI qualitatively provides a lens through which to examine the overlapping spatial, ethical, and temporal consequences for humans and the built environment. Urban planning researchers and designers can use HBI principles to humanise the sustainable smart city. © 2023 The Author(s).
ABSTRACT
The tourism sector was among the most affected sector during the COVID-19 pandemic and has lost up to USD 5.87 billion potential revenue. Since many countries closed the borders, including Indonesia, by applying travel restrictions and thus tourists postponed their visits. Whereas vaccine distribution has shown good progress as the vaccination percentage in Jakarta and Bali has shown promising results since the majority of its population has been vaccinated, and it helps many industries, including tourism, recover. However, the pandemic might change tourist behavior. In addition, information about tourist destinations is spread poorly in various sources, and it psychologically affects tourists' decision to visit. Many works have been published to address this issue with the recommendation system. However, it does not provide geopolitical variables such as PPKM in Indonesia to ensure safeness for the tourist. Therefore, this research aims to enhance innovations in the tourism industry by considering the geopolitics factor into the system using Multiple Linear Regression. The result of this research demonstrates the effectiveness of geopolitics added variable on three different cities Jakarta, Java, and Bali. It can be implemented in a wide area in Indonesia. For further research, the proposed model can be used in a wide area in Indonesia and developed for a more comprehensive recommendation system. © 2022 IEEE.

ABSTRACT
Using learning analytics and dispositional learning analytics in teaching is difficult. Examples of their use are required for higher educational institutions and teachers. In this paper, we present a flipped learning approach in online settings (due to COVID-19) with particular emphasis on learning analytics and dispositional learning analytics. For this, an understanding of flipped approaches (i.e., flipped classroom and flipped learning) as well as the role of technology in the teaching context is required and presented. The role of technology includes (1) a digital learning system, (2) a conferencing system, (3) the collection and use of learning analytics and dispositional learning analytics, and (4) content-specific technology. Additionally, our aim is to present students' course feedback results from quantitative research methods course practices (2020, 2021) for preservice teachers (i.e., students;N = 70). The content is highly challenging for these students, causing fear, frustration, anxiety, and boredom. Generally, the results for pedagogy were positive, but the results of students' learning perceptions were lower. Based on the approach and results, discussion with new insights is provided. © 2022 Copyright for this paper by its authors.

ABSTRACT
Goal. The aim of this paper is to determine the attitudes and opinions of the members of the Pensioners' Club of the city of Osijek after the education was carried out with the aim of training them in information and communication skills. Methodology. The paper presents the results of the research conducted through interviews and focus groups among retirees, the members of the Osijek Retirees' Club. The research examined the attitudes and opinions of 10 pensioners on the topic of education in terms of information and communication technologies during March 2022 using the interview method. After the interviews, the attitudes and opinions of the retirees related to the use of technology were examined in a focus group (1) in which 9 retirees participated (some of whom attended the education, some of whom did not). Finally, a focus group (2) in which 4 retirees participated examined their attitudes and opinions about virtual reality. The respondents wore VR glasses and observed the history of Osijek in the period from 1920 to 2020 by decades. More specifically, they observed how objects, houses, newspapers, furniture and similar things covered in the mentioned period looked. The paper presents the attitudes and opinions of the participants of the workshops, and is a continuation of the previous research, conducted before this training (Jakopec, Selthofer and Hocenski, 2022). Results. The results of the conducted interviews and focus groups indicate that the majority of retirees share the desire for learning and acquiring additional IT knowledge. They own at least one device (mostly a desktop computer or a smartphone) through which they visit social networks, search for necessary information and read the daily news. The respondents who participated in the research believe that they need more similar workshops in order to establish and expand their existing knowledge. After the workshops, the pensioners stated that they are fully aware of the advantages that IT knowledge brings them, and they relate this knowledge to the use of technology during the COVID-19 pandemic, when physically going to certain places (for example, to the doctor) was not possible. The results of the second focus group in which 3D reality was observed using VR glasses have shown that the respondents were not previously familiar with the concepts of virtual reality. According to the participants, the workshop lasted too short, they felt disoriented, and the glasses did not impress them too much. They also pointed out that they wore them for too short a time to highlight something as an advantage, they did not remember much of the presented content, but they found it interesting. Most of them stated that they would like to repeat the experience, but with better instructions and extended time of wearing glasses. Limitations. The research sample is limited to a specific subgroup of the retired members of the Club, and is therefore not representative of the entire population of retired people in the city of Osijek and in the Republic of Croatia. Value. The results of the research indicate the attitudes and opinions of people of the third age towards education in the field of information and communication technologies and virtual reality. The results of the research contribute to the implementation of the "Active pension” project. © 2023, Hrvatsko Knjiznicarsko Drustvo. All rights reserved.
ABSTRACT
The COVID-19 pandemic posed numerous challenges for instructors and students. Professors, for example, struggled to quickly and effectively migrate face-to-face courses to remote teaching modalities. What had not been anticipated, however, were the additional challenges to be managed when returning to face-to-face and in-person teaching. This reflective essay provides some insight into how faculty at the University of Puerto Rico attempted to modify teaching practices to re-engage disengaged students as they returned to the campus classroom. Also, recommendations about how to move forward by applying a pedagogy of renewal are made.
ABSTRACT
The analysis of current trends in the implementation of effective socio-economic solutions and their development under the influence of COVID-19 is made. The prospects of using innovative and telecommunication technologies, robotics, big data processing methods and knowledge management methods in the formation and management of global economic clusters were noted. The clustering of delivery robots under pandemic conditions by methods of machine learning was carried out. The peculiarities of COVID-19 assessment as the main formative factor influencing socio-economic decision-making on a global scale are disclosed. The necessity and possible consequences of adopting and implementing new decisions designed to minimize the negative effects of COVID-19 on Russian and global economies are discussed. It is noted that the design and development of innovations in the system of management and transfer of knowledge is an indispensable condition for the successful development of future socio-economic relations. On the basis of the obtained results conclusions are made about the background of the applied solutions, about the vector of their direction and makes it clear what should be paid special attention to when assessing the current situation in society and determine which solutions are most effective and how the social order should be transformed to successfully withstand the new challenges. © 2023 SPIE.
ABSTRACT
Touch-based fingerprints are widely used in today's world;even with all the success, the touch-based nature of these is a threat, especially in this COVID-19 period. A solution to the same is the introduction of Touchless Fingerprint Technology. The workflow of a touchless system varies vastly from its touch-based counterpart in terms of acquisition, pre-processing, image enhancement, and fingerprint verification. One significant difference is the methods used to segment desired fingerprint regions. This literature focuses on pixel-level classification or semantic segmentation using U-Net, a key yet challenging task. A plethora of semantic segmentation methods have been applied in this field. In this literature, a spectrum of efforts in the field of semantic segmentation using U-Net is investigated along with the components that are integral while training and testing a model, like optimizers, loss functions, and metrics used for evaluation and enumeration of results obtained. © 2022 IEEE.
ABSTRACT
Digital transformation, which significantly impacts our personal, social, and economic spheres of life, is regarded by many as the most significant development of recent decades. In an industrial context, based on a systematic literature review of 262 papers selected from the ProQuest database, using the methodology of David and Han, this paper discusses Industry 4.0 technologies as the key drivers and/or enablers of digital transformation for business practices, models, processes, and routines in the current digital age. After carrying out a systematic literature review considering key Industry 4.0 technologies, we discuss the individual and collective ways in which competitiveness in contemporary organizations and institutions is enhanced. Specifically, we discuss how these technologies contribute as antecedents, drivers, and enablers of environmental and social sustainability, corporate growth and diversification, reshoring, mass customization, B2B cooperation, supply chain integration, Lean Six Sigma, quality of governance, innovations, and knowledge related to dealing with challenges arising from global pandemics such as COVID-19. A few challenges related to the effective adoption and implementation of Industry 4.0 are also highlighted, along with some suggestions to overcome them.
ABSTRACT
The UK government is taking advantage of the new regulatory flexibility, afforded by Brexit, to boost the country's competitiveness in pharma On 1 Jan. 2021, the United Kingdom formally left the European Union to become a third country and no longer a member of the Union's single market and customs union. The UK has, for example, decided to draw up its own version of the EU chemicals legislation-called REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals)-which sets technical standards for chemical ingredients for medicines (1). Because the UK is a separate legal entity-a third country-the UK's excipient producers and their raw material suppliers have started to be concerned about procedures like customs declarations and rules of origin. [...]by 18 Feb. 2021 the UK had vaccinated 26% of its population versus 8% in Denmark-the leading EU country for vaccines availability-6% in Germany, and 5% in France (6). NICE needs to change Industry believes that the National Institute for Health and Care Excellence (NICE), the government's health technology assessment (HTA) body, is being too restrictive with its evaluation of digitalization products, which ultimately sets the price paid by the government for them (9).
ABSTRACT
The success of the cooperation between government and the private sector to rapidly develop and build capacity for vaccines and treatments to combat the COVID-19 pandemic is an example of what is possible, in the normally slow-acting and risk-averse pharmaceutical sector, say industry experts. Reducing barriers to CM One positive sign is greater acceptance of public-private partnerships by the United States (US) Food and Drug Administration (FDA) and the US Congress, due to the successes demonstrated during the pandemic response, said Jennifer Luray, vice-president of strategy and communications at ResearchlAmerica, during a panel discussion hosted by the US Pharmacopeia Convention (USP) (2). USP can help fill the gap that exists in access to knowledge, experience, and laboratory capabilities for PAT model development and process development, adds De Belder. " "Some PAT systems are more suited to a development environment, where the goal is to gain process understanding and knowledge about the product, but those systems may not be robust enough for routine deployment on a commercial process," adds Connelly.
ABSTRACT
The call for reshoring manufacturing may be answered in part by using these advanced technologies to produce APIs or to continuously manufacture drug products end-to-end, beginning with basic raw materials and ending with a finished drug form. The US Department of Defense's Defense Advanced Research Projects Agency (DARPA) has funded several continuous flow chemistry projects, promoting portable technologies that can be used to make medicines on-site in the field for the US military using a few essential raw materials. "To compete with the cost-effectiveness of offshore API manufacturing, innovative streamlined and automated systems are needed," notes Nathan Collins, chief strategy officer of SRI's Biosciences Division and the principal investigator for the ProSyn project. In mid-2020 the process development company doubled its R&D capacity and opened a lab to produce gram to kilogram-scale APIs and demonstrate its continuous flow manufacturing technology at pilot scale.

ABSTRACT
COVID-19 pandemic brought up issues with healthcare costs, national economic development and welfare of the society in forefront. Nations across the globe followed different approaches to deal with COVID-19, such as zero tolerance, herd immunity, containment to build treatment capability. National healthcare became a contentious sociopolitical issue involving healthcare costs, technologies and societal health. In the United States even during the COVID-19 pandemic, the government approach was pursuing a sustainable improvement in patient care through adoption of medical and information technologies. The national healthcare policies are framed around technological interventions with the assumption that deployment of technologies could keep healthcare costs under control and at the same time improve health outcomes. However, evidences show that the healthcare costs are in the rise even with impressive progress in technological deployment. This article highlights some of the recent trends in healthcare costs, technological preparedness, medical technology developments in managing COVID-19 pandemic. The US government mandated electronic health record (EHR) systems implementation and assess its impact on healthcare costs and health outcomes. This article emphasizes the need for understanding the interconnectedness of costs, technology and societal health.
ABSTRACT
The COVID-19 pandemic has highlighted the need for higher education institutions to modernize and embrace the post-digital age. This study evaluates students' perspectives of utilizing MS Teams as a means of facilitating remote learning during the pandemic. The Technology Acceptance Model (TAM) was employed as the theoretical framework to examine students' views on self-efficacy, facilitating conditions, ease of use, usefulness, and intention to use. The results showcase positive views of MS Teams, with self-efficacy rated the highest among the five constructs, followed by ease of use, facilitating conditions, intention to use, and usefulness. Additionally, no significant differences were found in students' perceptions based on gender. MS Teams has proven to be a successful platform for delivering online learning and communicating, bridging the divide of distance and time in teaching and learning. As discussions about the future of higher education in the post-pandemic world have commenced among academia and university officials, it is crucial to consider the impact of COVID-19 on student learning and provide suggestions for a more sustainable and effective post-pandemic education. © 2023 IEEE.
