In this work, the main trends in research and publication activity in digital transformation in the world and Ukraine are analyzed using meta- and bibliometric analysis. For this purpose, bibliometric data on scientific publications on the topic of digital transformations in the Google Scholar and Scopus databases were selected, which were additionally analyzed using the VOSviewer software package. Based on filtering the results obtained, an array was formed that included 366 scientific publications for 2019–2023 in Ukrainian in the Google Scholar database and 3,703 scientific publications in English for 2020–2023 in the Scopus database. Dynamic time analysis revealed a significant surge of scientific interest in the topic of digital transformations in recent years, while structural analysis revealed the multi-industry structure of existing research. The creation of bibliographic maps of keywords and publication maps allowed us to form an idea of the main thematic areas of research in the context of digital transformations and their opinion leaders. The data obtained became the basis for formulating recommendations for further areas of research in digital transformation, in particular, on the development of a unified roadmap for the digital transformation of education at different educational qualification levels and for various specialties. This will contribute to the formation of a single systemic approach to the digital transformation of Ukraine as a guarantee for the state’s sustainable development, well-being, strengthening of national security, speeding up the pace of European integration processes, as well as promoting national interests at the international level.

The purpose of the paper is to analyze the positioning of Ukraine in the global indices of innovative development and competitiveness, to evaluate the indicators of innovation activity and, based on the outcomes of the research, to determine the place of Ukraine in the global innovation space. The dynamics of innovation activity on an international scale based on the consolidated indicators of the Global Innovation Index are presented. Ukraine’s position in it and progress in achieving goals to better understand the processes that stimulate or constrain innovation are determined. Econometric methods to generalize the positioning of Ukraine in the global innovation space and the DEA method to study the relative individual effectiveness of the innovation environment and innovation activities in Europe are used.

The barbaric war of Russia against Ukraine is accompanied by the death of tens of thousands of people. Millions of Ukrainians were forced to leave their places of residence, hundreds of thousands had their homes completely destroyed, and a large part of the country's enterprises, energy and transport infrastructure was disabled. This war violates all international laws and, in fact, is a challenge to the entire civilized world. Its causes and consequences are discussed, analyzed, and considered by society and experts. Scientists do not ignore it either. The increase in publications on the topic of war and the uniqueness of this kind of research caused the desire to map the corresponding thematic landscape and identify the main trends. The methodological basis of analysis in the presented study was in-built Scopus instruments, Bibliometrix R package and Biblioshiny App, InfraNodus. The study includes two sections, namely, time section (compares publications for the entire period of the Russian armed aggression against Ukraine (2014–2023), as well as before and after the full-scale invasion (2020–2021 and 2022–2023), and geographical section (compares publications of international and Ukrainian scientific communities). The dynamics of publications, their structure by subject areas, countries, affiliations, authors, and sponsors were analyzed. According to the results of cluster, sentiment and narrative analysis, there is a shift in substantive emphasis after February 24, 2022 towards the interpretation of events as a full-scale war (52% of publications as a whole and 60% of publications by authors with Ukrainian affiliation), taking into account the consequences for the global energy, food, and other types of security. The identified structural gaps in the analyzed works create the basis for developing directions for overcoming the consequences of the war in various areas and post-war reconstruction of Ukraine.

The aim of the study is to assess the effectiveness of implementing an innovative technology for the production of a multi-component vegetable semi-finished product for functional food products. The proposed technology provides for gentle processing of agricultural raw materials and provides for preliminary preparation of raw materials (washing, cutting into plates 3…5 mm thick and 20…30 mm wide). They were previously blanched in a universal multifunctional apparatus at a temperature of 85…90°C for 2…3 minutes. In accordance with production needs, the puree-like multi-component mass is supplied for concentration in a rotary film evaporator at a temperature of 45…55°C to obtain a thick concentrate with a high content of dry matter (40…45%). The possibility of drying with simultaneous grinding in an infrared roller dryer at a temperature of 55…65°C and a final humidity of no more than 8.5% is also provided. The advantage of the multicomponent powder over the traditional apple powder has been proven – in particular, in terms of the content of dietary fiber (11.4 g), vitamin C (19.6 mg), anthocyanins (66.5 mg), proteins (7.2 g), fats (1.9 g) and antioxidant activity (52.1%). Adding the powder to the bread recipe contributed to an increase in the volume of the product by 5%, crumb moisture by 3.9%, as well as an increase in the freshness retention period to 90% on the third day. In meat products, replacing 8% of meat with a multicomponent ingredient increased the yield of the finished product to 93%, reduced heat loss and improved antioxidant resistance to 52%. A comprehensive assessment confirms the technological feasibility and socio-economic efficiency of the developed solution, which meets the requirements of sustainable production, localization, energy saving and import substitution in conditions of crisis challenges.

The market for information and communication services in Ukraine is analyzed based on statistical data. Its main segments by revenue, namely mobile communications and Internet services, are identified. The main regularities of setting tariffs for these services in countries of the world are determined, depending on the welfare of the population, the democracy index, the index of information and communication technologies, as well as the corruption perception index. Scatter diagrams of dependence of the tariffs on mobile communications and the Internet on the GDP per capita are built. The parameters of single-factor and multifactorial models of influence of the GDP per capita, the index of democracy, and the index of information and communication technologies on tariffs for mobile communications and the Internet by regions of the world are investigated. The conclusion is drawn that the tariff policy of the operators of Ukraine is aimed at reaching broad layers of the population, and even after taking into account the effect of the level of the country’s economic development, tariffs remain too low.

According to WEF, UNWTO, WTTC, World Travel & Tourism Market increased by 26,3% between 2010 through 2015 and now stands more than US$ 7,2 trillion (9,8% of global GDP). The number of international tourists increased by 75% and the number of persons employed in tourism around the world increased to 284 million. The objectives of this paper are: analysis of tourism competitiveness of Ukraine's regions on the basis of relevant index calculation in 2013-2015; ranking of regions; analysis of the dynamics of changes in index and rankings by region; evaluation of tourism competitiveness level of regions. As results of research the set of indicators was formed to reflect the tourism competitiveness from a regional perspective. The Travel & Tourism Competitiveness Index (TTCI) for 24 regions and Kyiv city in 2013-2015 was calculated and rating was constructed. It was established that 88% of regions have a positive trend in the index changing and there are only 3 regions with a negative one. The ranking leaders are Kyiv city (1st place), Lviv (2nd place) and Chernivetska (3rd place) regions. During 2013-2015, seven regions have worsened their positions in the overall rankings, losing from 1 to 9 positions; another nine regions on the contrary have risen in the rating by 1 to 9 positions; and other nine regions have saved their positions in ranking. It was established that 92-96% of regions have an intermediate level of tourism competitiveness in 2013-2015 and 4-8%> of regions have an upper-intermediate. The results of the study show that tourist industry of Ukraine's regions has an intermediate level of the development (68% of regions have TTCI >3,5 in 2015). It is proved by WEF calculation according to which TTCI of Ukraine is 3,83.
