    Globalisation and Digitalisation: The European Approach to Cutting-edge Educational Practices
    (2024-09-30) Martyniuk, Alla; Zabiiaka, Iryna; Shevchuk, Anastasiia; Lobanova, Svitlana; Hubina, Alla; Melnychuk, Olha
    The urgency of optimising the development of Ukraine’s education system is driven by the need to preserve intellectual potential and national identity against the backdrop of the priority of integrating into the European system in the context of post-war recovery. The research aims to identify gaps in existing studies on globalisation and digitalisation practices based on successful European experiences and propose a new research direction in immersive technologies. The innovative solutions proposed in the article pertain to immersive technologies integrated into the educational process to enhance material assimilation and create engaging experiences. The advantages of their application are highlighted, including the visualisation of abstract and complex learning concepts, stimulation of active participation in interaction with virtual objects and environments, development of creativity and problem-oriented thinking, and obtaining realistic experience. The study establishes that the implementation of advanced educational practices of the European community and the involvement of long-term international funding in synergy form potential optimal prerequisites for developing the higher education system in the national space through the differentiation of powers between various institutions, autonomy in the organisation of educational process management, and the formation of a competitive environment in the higher education sector.

    Deformability of a glued wooden beam with pre-stressed composite reinforcement
    (2024) Gomon, Petro; Babych, Yevgenij; Polishchuk, Mykola; Kysliuk, Dmytro Y.; Bandura, Irina; Pakholiuk, Orest; Shevchuk, Anastasiia
    The article proposes a method for pre-stressing a reinforced glued wooden beam that involves placing steel reinforcement in the form of metal rods in the compressed zone and pre-stressed composite reinforcement in the form of tape in the tension zone. The procedure for pre-stressing is outlined, and experimental studies of such bending elements have been carried out. Graphs of the distribution of deformations in both wood and reinforcement along the height of the calculated cross-section during pre-stressing and without pre-stressing are provided. It was found that the load-bearing capacity of the reinforced glued wooden beam increased by 45% during the pre-stressing process with composite reinforcement in the tension zone.

    Adhesion of Class A500C Steel Reinforcement to Concrete of Various Strengths
    (2026) Chapiuk, Oleksandr; Filipchuk, Sergiy; Suvorov, Oleksandr; Pakholiuk, Orest; Kusliuk, Dmytro; Zadorozhnikova, Iryna; Uzhegova, Olga; Shevchuk, Anastasiia
    New experimental data on the bond forces (bond stresses) between sickle-shaped ribbed steel reinforcement of class A500C and normal-weight concrete of various strength classes have been obtained. Pull-out tests of 16 mm diameter steel bars embedded in concrete prisms 5d (80 mm) high were conducted using a hydraulic tensile testing machine. An improved calculation methodology is proposed to ensure a reliable bond between A500C steel reinforcement and normal-weight concrete of varying strength levels. It was established that an increase in concrete strength leads to a proportional increase in the bond capacity of sickle-shaped reinforcement. A linear relationship between the maximum tangential bond stresses and concrete strength was identified, demonstrating good agreement with the experimental results. The proposed linear dependence can be applied in the design of reinforced concrete structures for calculating the ultimate bond strength between sickle-shaped steel reinforcement and normal-weight concrete of various strength classes.
