Opis:: This article deals with the basic principles of developing engobe compositions for facing and clinker ceramic bricks. The microstructure features of ceramic bricks have been studied, which must be considered when choosing the engobe composition and engobe products’ technology. The expediency of using alkaline and substandard kaolins as the main raw material, which improves the conditions for sintering ceramic coatings by applying the single annealing technology of construction ceramics, has been studied. Due to its higher annealing reactivity, compared to traditional clay materials, the experimental raw material in the engobe composition improves the adhesion of the coating to the ceramic base and increases the strength of the decorative and protective layer.

Opis:: Ukraine is characterised by active natural hazards processes within different structural, tectonic and landscape zones. In Middle Dnieper basin region mass movement processes have great impact on people’s livelihoods and infrastructure. These processes occur on the slopes with different geological structure. The determining causes include lithologic and stratigraphic conditions, hydrogeological regime, structural and textural peculiarities of rocks and the geomorphology of the slopes. Landslide inventory database has been developed based on long-term observations of more than 400 landslides and landslide-prone areas. This paper takes efforts forward by combining different geological and geophysical methods to advance the current understanding of landslide phenomena and contributing towards a better informed assessment of landslide hazard and risk. The developed methodology is implemented in a test sites of Kyiv region, covering an area of 18.3 km2 situated in the Middle Dnieper basin. Electrical Resistivity Tomography, Self-Potential and Infrared Thermography techniques were employed to investigate the lithostratigraphic sequences, the geometry of landslide body and potential mass movement. The results presented here confirm the potential of using an integrated approach that combines different field data to better plan mitigation activities and measures for the effective land management. This study will be useful in increasing the safety aspects of the infrastructures and lives and also for planning of research and developmental activities.

Opis:: The essence, purpose, tasks, approaches, principles, content, forms and methods of methodical training of future teachers of Physics, Mathematics and Computer Science, as well as Masters in Educational and Pedagogical Sciences are revealed. Methodical training of future teachers is considered as one that should provide a synthesis of subject, psychological, pedagogical and methodological knowledge, skills, abilities and personal qualities of applicants for Higher Pedagogical Education. As the analysis of the experience of the Faculty of Physics and Mathematics of H.S. Skovoroda Kharkiv National Pedagogical University, implementation of the developed concept of methodical training of future teachers allows to provide preconditions for creation of a trajectory of their further professional development focused on their personal and professional growth, successful professional self-realization. Key words: future teachers; Physics; Mathematics; Computer Science; Educology; methodical training.
