Experience of distance learning during COVID-19 pandemic among undergraduate nursing students

COVID-19 Pandemic has a huge influence on the learning process worldwide. To maintain student academic progress, learning activities were converted to distance learning to control the further spread of the COVID-19 virus. During this period several studies around the world were conducted to assess the effectiveness of distance learning. The results of these studies showed different perspectives, some of the students preferred e-learning while other preferred traditional methods. The aim of this study was to assess the experience of undergraduate nursing students who used distance learning during the COVID-19 pandemic. A quantitative, cross-sectional design was used to conduct the study. A convenient sampling approach was used to collect the data electronically via self-reported questionnaires. The study included 328 participants. The average score of the effectiveness domain was (2.58±0.68, medium level), and the satisfaction domain was (2.56±0.54, medium level). The results indicate that technical issues were the most significant barrier (75.6%) to distance learning, followed by physical problems, and decreased access to technological devices. Savings in transportation costs (74.1%), savings in time (71.6%), and the opportunity to review recorded lectures (67.4%) were the benefits of distance learning reported by nursing students during the COVID-19 pandemic. Most of the nursing students reported a positive preference for distance learning. Technical issues were the most significant barrier while decreased transportation costs were the most significant facilitator. These findings were consistent with other studies from different settings. Further research is needed to build upon these findings.

In Vivo Accelerator-Based Boron Neutron Capture Therapy for Spontaneous Tumors in Large Animals: Case Series

(1) Background: accelerator-based neutron sources are a new frontier for BNCT but many technical issues remain. We aimed to study such issues and results in larger-animal BNCT (cats and dogs) with naturally occurring, malignant tumors in different locations as an intermediate step in translating current research into clinical practice. (2) Methods: 10 pet cats and dogs with incurable, malignant tumors that had no treatment alternatives were included in this study. A tandem accelerator with vacuum insulation was used as a neutron source. As a boron-containing agent, 10B-enriched sodium borocaptate (BSH) was used at a dose of 100 mg/kg. Animal condition as well as tumor progression/regression were monitored. (3) Results: regression of tumors in response to treatment, improvements in the overall clinical picture, and an increase in the estimated duration and quality of life were observed. Treatment-related toxicity was mild and reversible. (4) Conclusions: our study contributes to preparations for human BNCT clinical trials and suggests utility for veterinary oncology.

How to avoid medical errors, how to respond and relate to them: a review of the scientific monograph «Defects in the provision of medical care»

Currently, the number of judicial proceedings on real and alleged offenses and disputes in area of provision of medical care has been exponentially increased. Some of such proceedings become publicly disclosed, but many more of them remain unnoted in mass media and civilian society as a whole. Increasing number of medical doctors has been accused of criminal offenses, being more often sentenced to real terms of imprisonment, showing a clear tendency to increase gravity of responsibility applied to medical doctors. This publication represents a peer-reviewed response of paramount importance to the book by A.A. Ponkina and I.V. Ponkin «Defects in the provision of medical care» raising ontological, value and technical issues for negative outcome of medical care – by the fault or in the absence of the fault of the doctor. The book puts the scientific basis beneath changes so much awaited by the Russian public health in relation to medical doctors, their social importance, objective limitlessness of their opportunities and capabilities in curing sick people and saving their lives.

Application of Digital Twins to Flexible Production Management: Taking a Shandong Factory as an Example

By enabling the merging of the virtual and real worlds, DT (Digital Twin) technology has considerably aided the development of businesses at both levels of digitization and networking in recent years. As an outcome, industrial research has shifted its attention to this new technology in the manufacturing business. However, there are still technical issues with DT technology, such as real-time data interaction, high integration of constituent elements, and high simulation. This paper proposes to solve these issues by presenting a framework that blends DT with 3D visualization technologies. A case study of an intelligent logistics management 3D scheduling system for a factory in Shandong verifies the applicability of digital twins to flexible production management. The example demonstrates that the framework can be synchronizing the virtual and real systems. Moreover, the framework can effectively cover the whole manufacturing life cycle, enhance production efficiency and product quality, and achieve flexible production management, helping the manufacturing industry's digital and intelligent transition.

Unlocking digital archives: cross-disciplinary perspectives on AI and born-digital data

Co-authored by a Computer Scientist and a Digital Humanist, this article examines the challenges faced by cultural heritage institutions in the digital age, which have led to the closure of the vast majority of born-digital archival collections. It focuses particularly on cultural organizations such as libraries, museums and archives, used by historians, literary scholars and other Humanities scholars. Most born-digital records held by cultural organizations are inaccessible due to privacy, copyright, commercial and technical issues. Even when born-digital data are publicly available (as in the case of web archives), users often need to physically travel to repositories such as the British Library or the Bibliothèque Nationale de France to consult web pages. Provided with enough sample data from which to learn and train their models, AI, and more specifically machine learning algorithms, offer the opportunity to improve and ease the access to digital archives by learning to perform complex human tasks. These vary from providing intelligent support for searching the archives to automate tedious and time-consuming tasks. In this article, we focus on sensitivity review as a practical solution to unlock digital archives that would allow archival institutions to make non-sensitive information available. This promise to make archives more accessible does not come free of warnings for potential pitfalls and risks: inherent errors, "black box" approaches that make the algorithm inscrutable, and risks related to bias, fake, or partial information. Our central argument is that AI can deliver its promise to make digital archival collections more accessible, but it also creates new challenges - particularly in terms of ethics. In the conclusion, we insist on the importance of fairness, accountability and transparency in the process of making digital archives more accessible.

Venous Air Microembolism in Chest CT Angiography: Evidence of Normalization of Deviance Phenomenon

Purpose This article provides evidence that detection of venous air microbubbles (VAMB) in chest computed tomography angiography (CTA) can be an indicator for “normalization of deviance” phenomenon in CT. Method and Materials Institutional review board-approved retrospective study, with waiver for informed consent. Contrast-enhanced chest CT performed during 6 months were reviewed for presence of VAMB in venous segments visible in chest CT (subclavian, brachiocephalic vein, superior vena cava) and cardiac chambers. VAMB volumes were quantified through a semiautomatic method (MIAlite plugin for OsiriX), using a region of interest (ROI) covering the bubble. With basal results, protocols for correct injection technique were reinforced, and VAMB were estimated again at 1 and 3 months. Six months later, questionnaires were sent to the CT technologists to inquire about their perception of VAMB. Descriptive measures with central distribution and dispersion were performed; statistical significance was considered at p < 0.05. Results A total of 602 chest CTA were analyzed, 332 were women (55.14%), with a median age of 58 (interquartile range [IQR] 44–72) years. Among those, 16.11% (100 cases) presented VAMB. Most were emergency department patients (51.6%), male (50.3%), with a median age of 54 (IQR 26) years. There was no difference on detection of VAMB regarding sex (p = 0.19), age (p = 0.46), or referral diagnosis (p = 0.35). Mean air bubbles volume was 0.2 mL (range 0.01–3.4 mL). After intervention, the number of exams with VAMB dropped to 3.29 % (3/91) (p < 0.001). On the 6-month query, 50% of the technicians still considered that VMAB is inevitable, and 60% thought that the occurrence is not associated to risk, and therefore, not actionable. Conclusion VAMB are a frequent finding in chest CTA, and being independent from patient-related variables, it is likely due to technical issues such as intravenous access manipulation during the exam. Reduction after reinforcement of proper performance, and certification of a low concern from CT technicians for any risk associated, provides evidence that there is normalization of deviance in this everyday procedure.

Egyptian Educators’ Online Teaching Challenges and Coping Strategies during COVID-19

The present descriptive study investigated the challenges experienced and the coping strategies used by Egyptian university educators from different institution types while teaching online during the pandemic. The cross-sectional study drew participants (N = 222) from three different academic institution types, private universities, public universities, and adult education institutions, who responded to a survey that examined the technical, professional, administrative, social, and psychological challenges teachers encountered as well as their coping strategies. Data were analyzed quantitatively and qualitatively. Results indicated that the challenges and coping strategies reported by teachers varied according to the teaching context and the requirements of each academic institution. The most reported challenges experienced were exhaustion, internet problems, technical issues, and anxiety. Despite the challenges, participants reported a few positive effects, including feeling more productive, being motivated to learn something new, feeling appreciated by the students and administration, and feeling confident using online teaching tools. Results also revealed that the participants used social and professional strategies to cope with the circumstances accompanying the sudden shift to online teaching. The results indicated how challenges faced by educators from different institution types may diminish with more training on, and experience with, online teaching, forming communities of practice as well as other coping strategies they developed. Such findings should be helpful to educators, institutions, and policymakers in different academic institutions all over the world and in various teaching contexts.

Healthcare professionals' experience of performing digital care visits - a scoping review

Background: The use of patient initiated digital care visits has been increasing and even more so in the era of the Coronavirus (COVID-19) pandemic. Learning more about healthcare professionals’ experience of using such technology would provide valuable insight and a basis for improvement of digital visits.Aim: This study sought to explore the existing literature on healthcare professionals’ experience of performing digital care visits.Methods: A scoping review was performed following Arksey & O’Malley’s proposed framework and utilizing the Preferred Reporting Items for Systematic reviews and Meta-Analyses – Extension for Scoping Reviews (PRISMA-ScR) checklist. Three large databases – PubMed, Web of Science and IEEE Xplore were searched, and 28 studies were included in the review. The collected data was analyzed using thematic content analysis.Results: Five main themes were identified in the literature: positive experiences/benefits, facilitators, negative experiences/challenges, barriers, and suggestions for improvement. Healthcare professionals mostly reported having overall positive experience with digital visits and saw benefits for themselves and the patients – efficiency, convenience, accessibility, and new perspectives in remote care to name a few. However, opinions were mixed or negative regarding the complexity of decision making, workload and workflow, suitability of this type of care and other challenges. The suggestions for improvement included training and education, improvements within system and tools and support for professionals.Conclusion: Despite overall positive experience and benefits for both professionals and patients, clinicians reported challenges and issues they faced when using digital care visits: physical barriers, technical issues, suitability concerns and others. Digital care visits could not fully replace face-to face visits.
