ABSTRACT
The purpose of the research in this article is to identify the main trends in the development of aviation industry during COVID-19 pandemic. The authors identify the main problems facing aviation industry in the context of the developing world crisis and possible ways to solve them. As a working hypothesis, it is proposed to form the basic concepts necessary for preliminary preparation and implementation of operational measures to restore passenger and cargo aviation. Taking into account the main threats facing the aviation industry during COVID-19, the article proposes the organizational and economic mechanisms to restore the industry. Short-term, medium-term and long-term recovery scenarios are considered, taking into account the relevant factors that have a certain impact. The study is based on a comprehensive analysis of documentary data provided by government agencies in a number of European countries. Openly printed materials from the International Civil Aviation Organization (ICAO) are also used in the analytical report "Consequences of new coronavirus COVID-19 in civil aviation: analysis of economic impact". The research methods are working papers from the European and North Atlantic Offices of ICAO aimed at rebuilding the aviation industry after COVID-19 pandemic. An analysis of global and Russian passenger traffic for Q1-Q4 (quartile) of 2021 and a development forecast for Q1-Q2 of 2022 is provided. The scenario problems facing the aviation industry in the context of COVID-19 crisis are identified. There are key concepts necessary to start preparation and implementation of effective measures to restore the aviation industry. © 2022 Institut za Istrazivanja. All rights reserved.
ABSTRACT
The purpose of the research in this article is to investigate the main trends in the development of the different industries during the COVID-19 pandemic, to identify the main problems facing the different industries in the context of the global crisis, as well as to form the basic concepts necessary for a real recovery of the global industry. The authors identify the main problems facing the aviation industry in the developing world crisis and possible ways to solve them. As a working hypothesis, it is proposed to form the basic concepts necessary for preparing and implementing operational measures to restore passenger and cargo aviation. Considering the main threats facing the aviation industry during COVID-19, the article proposes the organizational and economic mechanisms to restore the industry. Furthermore, several recovery scenarios are considered, considering the relevant factors that have a particular impact. Next, a novel mathematical model for pharmaceutical products, which are the most important in COVID-19 pandemics, is proposed. Moreover, the model considers the uncertainty, and a robust optimization approach is applied. The study is based on a comprehensive analysis of documentary data provided by government agencies in several European countries. An analysis of global and Russian passenger traffic for Q1-Q4 (quartile) of 2020 and a development forecast for Q1-Q2 of 2021 is provided. The scenario problems facing the aviation industry in the context of the COVID-19 crisis are identified. There are key concepts necessary to prepare and implement effective measures to restore the aviation industry. © 2022 Alexey I. Tikhonov et al., published by Sciendo.
ABSTRACT
The paper examines the digital transformation of organizations and the problem of low efficiency of organizations with a low level of digital development. The authors study the dependence of the growth rate of the company’s digitalization on demand for consumer interaction between the company and the consumer. Additionally, the authors note the relationship between the type of company and the rate of its digitalization, as well as the potential risks of digitalization and its benefits in the interaction between individuals and the government. The paper aims to review and identify the relationship between organizational performance and digital development. The data reviewed confirm this relationship. Moreover, the data indicate that digitalization provides new opportunities for organizations to interact with customers and users and increase the customer inquiry on the digital level of organizations, which creates the need for digitalization of organizations. The authors identify the risks of digitalization, such as the reduction of low-skilled jobs, which, combined with economic shocks, can lead to a significant social stratification of citizens without government intervention. It is also noted that the COVID-19 pandemic has been a significant impetus for accelerated digital development. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
The article deals with the structure and methods of construction of the course 'Problem Solving with Python' using STEM and STEAM technologies. The course is built on the principle of 'visualization and problem solving head first'. The techniques are offered to make the course easy to understand, including operations with NumPy arrays and slices, libraries of the Python ecosystem, domain-specific languages. It is shown that visualization in problem solving increases student interest. The techniques of conducting the course in the conditions of Covid-19 pandemic are offered. © 2021 IEEE.
ABSTRACT
Obtaining a pure recombinant Modified Vaccinia Ankara (MVA) virus is a multistage, time-consuming procedure. We describe a novel single-tube real-time PCR which enables determination of the amount of wild type and recombinant viruses and their ratio in plaques. Use of the real-time PCR significantly reduce the time and efforts needed to obtain purified recombinant MVA. The new approach has been applied to generate recombinant MVAs encoding different SARS-COV-2 antigens.
