Background: The modern education system is undergoing constant transformation under the influence of digital technologies that are being introduced into the learning process. Although digital technologies are widely used in foreign language learning, their advantages are controversial and require further study to determine their applicability. Therefore, the aim of this study was to determine the effectiveness of implementing digital technologies in foreign language teaching methods under experimental conditions at a local educational institution in Ukraine. Materials and Methods: The study used methods of analysis, synthesis, experimentation, testing, surveying, and statistical and graphical comparison. Results: The study involved 52 first-year students of the Faculty of Education who had taken an optional course in English. Depending on the teaching methodology, the students were divided into two groups: Group I (n = 26)—hybrid teaching methodology; and Group II (n = 26)—traditional methodology. The testing revealed higher results in writing, vocabulary, grammar, pronunciation, and understanding of the context of video and audio materials, and text in Group I, which used digital technologies (electronic dictionaries, artificial intelligence, online learning applications, video and audio materials). In contrast, Group II showed better results in communication skills and dialogue skills, which were associated with a greater number of tasks involving live communication in the group. The survey results showed higher motivation after the course among students in Group I and a higher level of satisfaction with the course. In contrast, in Group II, the level of motivation after the course decreased, which was associated with a lower level of satisfaction with the course and lower results in acquiring linguistic skills. Conclusion: The results of the study showed the high effectiveness of digital technologies for learning a foreign language, which should be combined with live communication to improve communication skills and the ability to conduct a dialogue. Another positive aspect of digital technologies in foreign language learning was identified as a positive impact on motivation to learn and satisfaction with the course.
Digital psychological support for students under martial law using a chatbot, as an analog of signal filtering in communication systems

The article analyses modern approaches to the creation of chatbots and their use in the field of psychology and education. The main problems that arise in this area are identified, in particular, the need to ensure confidentiality, adaptation to the emotional state of users and integration with external information systems. A prototype of a chatbot for psychological support of higher education students has been created. The use of the GPT model is proposed to ensure the accuracy and adaptability of interaction. The OpenAI platform with the MyGPTs function was chosen, which allowed the chatbot to be adapted to the needs of users by downloading methodological materials and instructions. The chatbot was tested on real-life scenarios. Chatbot functions as a signal filter-similar to physical filters in communication systems. A survey among higher education students confirmed that the developed bot meets the requirements of modern digital solutions in psychological support, provides prompt feedback and creates a sense of emotional support. The results of the study can serve as a basis for further improvement of the chatbot and integration of additional features such as voice responses and interactive exercises.
Study of low-cycle fatigue of concrete bonding to sickle-shaped reinforcement

The article definition of low-cycle bond fatigue between concrete and reinforcing bars is presented. It has been experimentally established that low-cycle bond fatigue of reinforcement in concrete under high-level cyclic loading occurs during the elastic-plastic slip of the reinforcing bars. Furthermore, a formula is proposed to describe the low-cycle bond fatigue of concrete with deformed bars. This formula shows good agreement with experimental data; for the materials investigated, the relative low-cycle endurance value constitutes 0.88.
