ABSTRACT
Visually impaired people require support with regular tasks including navigating, detecting obstacles, and maintaining safety, especially in both indoor and outdoor environments. As a result of the advancement of assistive technology, their lives have become substantially more convenient. Here, cutting-edge assistive devices and technologies for the visually impaired are reviewed, along with a chronology of their evolution. These methodologies are classified according to their intended applications. The taxonomy is combined with a description of the tests and experiments that can be used to examine the characteristics and assessments of assistive technology. In addition, the algorithms used in assistive devices are examined. This paper looks at solar industry innovations and promotes using renewable energy sources to create assistive devices, as well as, addresses the sudden advent of COVID-19 and the shift in the development of assistive devices. This review can serve as a stepping stone for further research on the topic. Copyright © 2022 The Author(s)
ABSTRACT
The primary objective of this study is to determine the effect of the COVID-19 pandemic on a representative sample of Bangladeshi uni- versity students. The study conducted a cross-sectional approach including HADS (Hospital Anxiety and Depression Scale) and CAS (Coronavirus Anxiety Scale), obtaining sufficient data to evaluate the correlation between COVID- 19 Lockdown lifestyle and psychological impact on the students. The CAS (Coronavirus Anxiety Scale), Anxiety and Depression models were constructed to predict individuals' psychotic state, and an indisputable interpretation process has been consummated to assemble sufficient results. The study conducted an unequivocal evaluation to observe the crucial socio and environmental factors associated with young age, low socioeconomic position, gender, scholastic lifestyle, immobility, solitary, academic and occupational impediments. © 2022 ACM.
ABSTRACT
This opinion paper addresses and contributes to the discourse on whether there is a central artifact that captures the essence of the information systems (IS) discipline. It argues that the IS discipline can, and should be, faithfully captured by an IS artifact. We offer a theoretical conception of the IS artifact by drawing upon General Systems Theory (GST). Key concepts of GST are distilled as meta-principles which inform our formulation of the IS artifact. We use the meta-principles of the IS artifact to develop salient assertions that theorize what an ‘IS’ is. To demonstrate the appropriateness of our conception, we illustrate how the assertions we developed are consistent with patterns related to emerging topics in IS research, notably, healthcare and IT, and Fintech. We formulate a research agenda on these emerging topics—based upon the conceptions developed in the paper—to guide future research. We conclude with the contributions and implications of our study, including the relevance for IT-enabled work in the era of the COVID-19 pandemic. © 2020 John Wiley & Sons Ltd
ABSTRACT
Professor Bidyut Kanti Datta, a renowned professor of the Department of Pharmacy, Faculty of Pharmacy, University of Dhaka, died at the age of 73 on Friday 11 September 2020 in Canada (Canadian time 7.10 am and BD time 5.10 pm), as a consequence of COVID-19 infection followed by pneumonia. This article is a brief review of his research work where the authors of this article are immensely proud to be associated with. Prof Datta published more than 60 research articles in reputed journals, and the lead author (SDS) of this article, one of his former students from the University of Dhaka, is a co-author of 20 of those publications. These 20 publications resulted from a long-standing research collaboration that spanned over two decades, especially research involving various Bangladeshi species of the genus Polygonum L. of the family, Polygonaceae, and they demonstrate the breadth and depth of research activities that Prof Datta was involved in, and his long-standing commitment to research that underpinned and enriched his teaching offerings to hundreds of students he taught in higher education sector in Bangladesh.
ABSTRACT
