ABSTRACT
The paper is devoted to the analysis of the spread of the COVID-19 pandemic in Ukraine based on finding the correlation between search terms in Google search engine and laboratory-confirmed cases. Statistics were obtained from open sources. The analysis was performed on matrices based on the Pearson correlation coefficient. To do this, we analyzed 25 typical search phrases, and after grouping them-7 remained. The data were reduced to the same discreteness. Correlation matrices were calculated for each wave of the pandemic and for altogether. As a result, the correlation between search phrases and laboratory-confirmed cases was observed only in the second and third waves of the pandemic. Moreover, in the first wave, the preconditions for its occurrence were found;in the second-Pearson's correlation coefficient was 0.74, and in the third wave, it decreased to 0.57. Other correlations that are specific to each pandemic wave are also analyzed. Additionally, it was proved that polynomials of the 6th degree most effectively restore lost data. © 2022 IEEE.
ABSTRACT
India urgently requires technological solutions to resolve its pressing sustainability issues. The study, therefore, analyzed published blog content to explore how drones were being used to promote the United Nations sustainable development goals in India. Blog entries were retrieved through the Google search engine and screened to select 35 blogs, which contained sustainable drone applications and drone operation policies in India. Blogs published from 2016 to 2021 were analyzed through qualitative content analysis using a phenomenological approach. The study identified four themes and ten sub-themes related to drone use for sustainability in India. Themes included drone applications for sustainable management of natural resources, drone use for sustainable agriculture, drone implementation for other sustainability purposes, such as biodiversity conservation, and rules and regulations for drone use that enhance sustainability. The study recommends commercializing India's drone industry to promote research on finding solutions to sustainability issues in various sectors. © 2022 IEEE.
