V.; Lebedev S. S. Короткий огляд (реферат): This study considers the methodology of synergistic management of innovation processes. One of the main results of this study is the analysis of the influence of a nonlinear (quadratic) controller on the properties of a dynamic model, which is presented in the form of a traditional logistic-type differential equation. The conditions for obtaining the characteristic values of the controller parameters for a system with two equilibrium positions are determined. It is found that a greater value of the characteristic indicator of the equilibrium position corresponds to a stable equilibrium position of the innovative system, and a smaller value corresponds to an unstable one. It is proved that when both equilibrium positions are close in value of the characteristic indicator, a saddle-nodal bifurcation occurs, and an analysis of the mechanism of loss of stability occurring in the system is also carried out. It is shown that this can lead to undesirable effects, such as a catastrophic loss of stability of the "fold" type. 2026-01-01T00:00:00Z https://repository.hneu.edu.ua/handle/123456789/41620 Назва: Sustainability as a Topic in German as a Foreign Language Classes Автори: Tsypina D. S. Короткий огляд (реферат): This article examines the concept of Education for Sustainable Development (ESD) is gaining increasing importance across all areas of education. Combining German as a Foreign Language instruction with sustainability offers the opportunity to link language learning with socially relevant topics such as the environment, social justice, and global responsibility. ESD aims to empower learners to act responsibly and with a focus on the future. Sustainability encompasses ecological, economic, and social dimensions. In current educational discourse, ESD is increasingly being integrated into language teaching contexts, for example through thematic modules in teacher training. It discusses that the central didactic approach is Content and Language Integrated Learning (CLIL) or, in Germany, language-sensitive subject instruction. Sustainability topics are particularly well-suited because they are relevant to learners’ everyday lives, promote communicative skills, and open up intercultural perspectives. The study concludes that the integration of sustainability into German as a Foreign Language instruction offers great potential, including the integration of language learning and social education, the promotion of practical skills, and the strengthening of intercultural perspectives. At the same time, there is a need for further research and development, particularly regarding teaching materials and the integration of sustainability into the curriculum. 2026-01-01T00:00:00Z https://repository.hneu.edu.ua/handle/123456789/41619 Назва: Online Foreign Language Learning: Challenges and Solutions Автори: Tsypina D. S. Короткий огляд (реферат): The rapid growth of digital technologies has transformed foreign language education, making online learning an essential component of modern educational systems. Online foreign language learning offers flexibility, accessibility, and personalized learning opportunities; however, it also presents several pedagogical, technological, and psychological challenges. This article examines the major challenges associated with online foreign language learning, including limited interaction, reduced learner motivation, technological barriers, assessment issues, and cultural limitations. Furthermore, it discusses evidence-based solutions that educators and institutions can implement to improve learning outcomes. The study concludes that successful online foreign language learning requires an integrated approach combining effective instructional design, appropriate technology, learner support, and innovative teaching methodologies. 2026-01-01T00:00:00Z https://repository.hneu.edu.ua/handle/123456789/41618 Назва: The Marketing Strategy of Business in the Context of Digital Transformation Автори: Malafieiev T. R.; Misiura Ie.Iu.; Pyvavar I.V.; Lytvynenko O. D. Короткий огляд (реферат): The relevance of the study is determined by the fact that the digital transformation of the modern economy is significantly changing approaches to business management and the formation of enterprise marketing strategies. The rapid development of digital platforms, artificial intelligence, big data, omnichannel communications, and automated management systems creates new conditions of competition in which the speed of interaction with consumers, content personalization, digital trust, and the ability of businesses to adapt quickly to market changes become decisive factors. For Ukrainian enterprises, the issue of transforming marketing strategies is particularly relevant under conditions of martial law, economic instability, business relocation, and changes in consumer behavior. Under such conditions, traditional marketing approaches are gradually losing their efficiency, creating the need for new strategic marketing models focused on digital flexibility, customer orientation, social responsibility, and the use of modern digital technologies. The aim of the article is to examine contemporary approaches to the formation of business marketing strategies in the context of digital transformation, to determine the role of digital technologies and artificial intelligence in the development of marketing communications, and to substantiate an innovative model of digital marketing resilience for Ukrainian enterprises operating under conditions of an unstable environment. The study employs methods of systemic, integrated, and process-based approaches, as well as methods of analysis and synthesis, comparison, generalization, elements of economic-statistical analysis, and case study analysis of contemporary Ukrainian business practices. The information base of the research consists of academic publications, analytical reports, statistical data, and the results of contemporary studies in the fields of digital marketing, e-commerce, AI marketing, and business digital transformation for the period 2022–2026. The study examines the impact of digital technologies, omnichannel platforms, big data, AI-driven personalization, CRM systems, customer journey 360°, and socially responsible marketing on the effectiveness of enterprise marketing activities. The results of the study identify the key directions of marketing strategy transformation in the digital environment and determine the specific features of Ukrainian business adaptation to wartime conditions and high market instability. It was found that the digitalization of marketing activities contributes to increasing the speed of managerial decision-making, the personalization of consumer interaction, the development of omnichannel communications, and the strengthening of enterprises’ competitive advantages. The study found that the highest efficiency is achieved through the comprehensive integration of AI technologies, data analytics, digital platforms, and socially responsible branding into a unified system of strategic marketing management. It has been proved that, under modern conditions, business competitiveness largely depends on the level of digital flexibility, the adaptability of marketing strategies, and the ability to build consumer trust within the digital environment. The scientific novelty of the research lies in the improvement of the model of digital marketing resilience, which is based on the interaction of four key components: Resilience (adaptability and anti-crisis resilience), Relevance (relevance through personalization), Responsibility (brand social responsibility), and Reinvention (continuous digital renewal). Practical recommendations are proposed regarding the integration of AI solutions into enterprise marketing activities, the development of employees’ digital competencies, the implementation of MarTech tools, omnichannel platforms, and data-driven approaches to ensure the long-term resilience and competitiveness of businesses in the digital economy. 2026-01-01T00:00:00Z
