Department of hydraulic engineering and hydraulics FGBNU «VNIIGiM them. A.N. Kostyakova «has a long history. For many years, the department’s staff has been such scientists and water engineers with extensive experience as M.A. Volynov, V.S. Verbitsky, S.S. Medvedev, N.V. Lebedev, B.C. Panfilov, T.G. Voynich-Syanozhentsky, V.A. Golubkova, G.V. Lyapin and others. The department solved a wide range of tasks, the main areas of research were the following: – theoretical and applied hydrodynamics and hydraulics, with reference to the open channel flows that affect the state and level of safety of the hydraulic structures; – integrated use and protection of water bodies – water sources and water sources of water resources used in land reclamation; – development of measures and technical solutions for the protection of objects from the negative effects of water; – theoretical substantiation of works to improve the safety level of the GTS (declaration); – development and implementation of digitalization methods for solving design, construction, operation and control of landreclamation facilities. Currently, promising areas of research is the development of a decision-making algorithm in the designation of measures to rationalize the provision of resources to water amelioration. The algorithm is developed on the basis of a detailed study, systematization and processing of data both on safety and on the efficiency of systems and structures, ensuring the delivery of irrigation water of the required quality and in sufficient quantity from a water source to the field.

Aim. Proper development of animal breeding in the conditions of current global problems and the decrease of anthropogenic burden on environment due to greenhouse gas emissions, caused by animal breeding activity, require the study of interaction processes between animal breeding and external climatic conditions. Methods. The theoretical substantiation of the problem was performed based on scientifi c literature, statistical informa- tion of the UN Food and Agriculture Organization and the data of the National greenhouse gas emissions inventory in Ukraine. Theoretically possible emissions of greenhouse gases into atmosphere due to animal breeding in Ukraine and specifi c farms are calculated by the international methods using the statistical infor- mation about animal breeding in Ukraine and the economic-technological information of the activity of the investigated farms. Results. The interaction between the animal breeding production and weather-and-climate conditions of environment was analyzed. Possible vectors of activity for the industry, which promote global warming and negative processes, related to it, were determined. The main factors, affecting the formation of greenhouse gases from the activity of enterprises, aimed at animal breeding production, were characterized. Literature data, statistical data and calculations were used to analyze the role of animal breeding in the green- house gas emissions in global and national framework as well as at the level of specifi c farms with the consid- eration of individual specifi cities of these farms. Conclusions. Current global problems require clear balance between constant development of sustainable animal breeding and the decrease of the carbon footprint due to the activity of animal breeding.

Hruntova T. V., Yechkalo YU. V., Stryuk A. M. and Pikilʹnyak A. V. Augmented Reality Tools in Physics Training at Higher Technical Educational Institutions. Research goal: the research is aimed at theoretical substantiation of applying the augmented reality technology and its peculiarities at higher technical educational institutions. Research objectives: the research is to solve the problems of determining the role and place of the technology in the educational process and its possible application to physics training. Object of research: teaching physics to students of higher technical educational institutions. Subject of research: the augmented reality technology as a component of the training process at higher educational institutions. Research methods used: theoretical methods include analysis of scientific and methodological literature; empirical methods include studying and observation of the training process. Research results: analysis of scientific publications allows defining the notion of augmented reality; application of augmented reality objects during laboratory practical works on physics is suggested. Main conclusions. introduction of the augmented reality technology in thetraining process at higher technical educational institutions increases learning efficiency, facilitates students’ training and cognitive activities, improves the quality of knowledge acquisition, provokes interest in a subject, promotesdevelopment of research skills and a future specialist’s competent personality.

The aim. The karate competition requires the athlete to have a comprehensive manifestation of motor abilities. At the same time, the motor-related area is closely connected with function of the auditory analyzer. Consequently, auditory deprivation affects all types of motor abilities, but, first of all, it affects coordination abilities, since they are implemented on a defective basis of the sensory systems involved in controlling movements. Technical means (punches and kicks, blocks) and tactical means (instant assessment of the situation and making the right decisions) of traditional karate effectively affect the correction of various manifestations of motor coordination. Moreover, the above mentioned karate means affect motor coordination through motor experience in the form of complicating previously mastered movements and mastering new movements with increased coordination difficulties. Methods and organization of the study. We used the following set of complementary theoretical methods to meet the challenge of theoretical substantiation of the research: analysis of psychological, pedagogical and methodical literature, scientific articles on adaptive physical culture, abstracting, generalization and concretization. Results. The research revealed the most common deviations in the manifestation of various components of coordination abilities of children with auditory deprivation. We specified sensitive periods of development of this type of motor qualities in children with hearing impairments. We identified basic karate techniques and actions, which favorably influence the course of development of coordination abilities. Conclusion. Correction and development of the coordination abilities of children with hearing impairments represent the primary task of adaptive physical education. The most favorable age is primary school age. Techniques and actions of traditional karate have a high potential of effective impact on all types of coordination abilities of children.

The theoretical substantiation of pyloroplasty as a therapeutic method in adults is based on the provisions, which are still very problematic today. Russian authors (Breitsev, Grekov et al.), who first proposed this operation in adults, set indications for this kind of intervention very broadly and considered it indicated not only for pylorospasm without visible ulcer, but also for ulcers of the small curvature and for ulcers of the 12th bowel. At the same time these authors proceeded from the position that pylorospasm is the central point in the pathogenesis and course of ulcers and they considered its elimination to be very important in the operative treatment of ulcers.

This article discusses the problem of assessing the effectiveness of the rehabilitation process. The assessment of the effectiveness of the rehabilitation process is recognized by many researchers as one of the most difficult in the theoretical substantiation of the process of rehabilitation and habilitation, in this regard, there are no uniform approaches to assessing the effectiveness of rehabilitation today. The article presents studies by several authors on this issue. Rehabilitation of patients after a stroke most often occurs with the use of rehabilitation complexes. The possibility of applying the assessment of the effectiveness of rehabilitation to such complexes is very relevant, since at the moment there is no unified system for determining the quality of rehabilitation complexes.
