Analysis of Peculiarities of Using Digital Technologies in the University Professional Training Content

The relevance of the study is due to the increasing role of digital technologies in education. The abrupt shift of universities to distance learning during the COVID-19 pandemic has created new challenges. The purpose of this article is to analyze modern problems of traditional e-learning systems and identify the most effective digital technologies for improving the design system and implementing the content of professional educational programs at the university in the context of digitalization. Scientific articles in journals included in the Scopus database over the past five years, official websites of universities and their reports on the use of modern digital technologies were used as a statistical and empirical base for the study. Multiple comparative case studies and content analysis were applied. To solve the identified problems, such modern digital technologies and methods as cloud computing, adaptive design, big data, 3D printing, wearable technologies and gamification were proposed. The paper proposes an updated digital education system model at the university consisting of such elements as Instructors & Students, Master Courses, Content Delivery, Courses Collaboration, Progress Tracking, Assignments, Practices and Exams. The conclusions and recommendations formulated in this study can be used by different educational systems and universities

Problems of business processes transformation in the context of building digital economy

© Entrepreneurship and Sustainability Center. All rights reserved. The article explores the main problems and features of one of the most relevant phenomena today-digital transformation, which implies fundamental changes in the activities of organizations based on the use of digital technologies. The paper reviews sources on the problems of building a digital economy and moving a business to the digital level. The purpose of this study is to identify t he main difficulties for the restructuring of organizations' processes on a digital format, as well as the formation of the theoretical and conceptual foundations of digital business transformation in the face of uncertainty and variability of the modern business environment. Using the methods of analysis, generalization, comparison, synthesis, deduction, induction, the essence of digital transformation is studied, Russia's positions among other countries in terms of readiness for the digital economy are analyzed, problems and barriers that impede the process of digital transformation for Russian and foreign companies are formulated. Based on the use of a systematic approach, methods of scientific abstraction, economic modelling, the work identifies the main functional areas of change, presents a loop of digital business transformation that reflects its main stages, necessary components and changes, and describes key segments of new digital business models of companies. The results can be used to conduct further theoretical and methodological and practice-oriented research in the field of digital business transformation, and can also be used by design teams of organizations to analyze the problems of switching to a digital format, develop a digital transformation strategy and rebuild a business model

Risk factors for systemic reactions in typical cold urticaria: Results from the COLD-CE study

Background: Cold urticaria (ColdU), that is, the occurrence of wheals or angioedema in response to cold exposure, is classified into typical and atypical forms. The diagnosis of typical ColdU relies on whealing in response to local cold stimulation testing (CST). It can also manifest with cold-induced anaphylaxis (ColdA). We aimed to determine risk factors for ColdA in typical ColdU. Methods: An international, cross-sectional study COLD-CE was carried out at 32 urticaria centers of reference and excellence (UCAREs). Detailed history was taken and CST with an ice cube and/or TempTest® performed. ColdA was defined as an acute cold-induced involvement of the skin and/or visible mucosal tissue and at least one of: cardiovascular manifestations, difficulty breathing, or gastrointestinal symptoms. Results: Of 551 ColdU patients, 75% (n = 412) had a positive CST and ColdA occurred in 37% (n = 151) of the latter. Cold-induced generalized wheals, angioedema, acral swelling, oropharyngeal/laryngeal symptoms, and itch of earlobes were identified as signs/symptoms of severe disease. ColdA was most commonly provoked by complete cold water immersion and ColdA caused by cold air was more common in countries with a warmer climate. Ten percent (n = 40) of typical ColdU patients had a concomitant chronic spontaneous urticaria (CSU). They had a lower frequency of ColdA than those without CSU (4% vs. 39%, p =.003). We identified the following risk factors for cardiovascular manifestations: previous systemic reaction to a Hymenoptera sting, angioedema, oropharyngeal/laryngeal symptoms, and itchy earlobes. Conclusion: ColdA is common in typical ColdU. High-risk patients require education about their condition and how to use an adrenaline autoinjector

The global impact of the COVID-19 pandemic on the management and course of chronic urticaria

Introduction: The COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown. Aim: To understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19. Materials and Methods: Our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences. Results: The COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers of patients treated as compared to before the pandemic. Reduced patient referrals and clinic hours were the major reasons. Almost half of responding UCARE physicians were involved in COVID-19 patient care, which negatively impacted on the care of urticaria patients. The rate of face-to-face consultations decreased by 62%, from 90% to less than half, whereas the rate of remote consultations increased by more than 600%, from one in 10 to more than two thirds. Cyclosporine and systemic corticosteroids, but not antihistamines or omalizumab, are used less during the pandemic. CU does not affect the course of COVID-19, but COVID-19 results in CU exacerbation in one of three patients, with higher rates in patients with severe COVID-19. Conclusions: The COVID-19 pandemic brings major changes and challenges for CU patients and their physicians. The long-term consequences of these changes, especially the increased use of remote consultations, require careful evaluation. © 2020 The Authors.
