The aim of the article is to study the theoretical aspects of innovative development of the region. Method-ology. To solve the tasks set in the article, a wide range of theoretical and empirical methods of scientific knowledge were used: theoretical generalization - in clarifying the content of the definition of «innovative potential of the region», «innovative development of the region»; synthesis – in the development of the sequence of stages of innovative devel-opment of the region, statistical methods of comparative analysis to study the level of innovative development of the regions of Ukraine Results. It is determined that the tasks of innovative development of the region are to provide its resources and create conditions for the transfer of results between stages of the innovation process through the activi-ties of regional development institutions. In the innovative development of the region it is necessary to take into account the role of different resources in the creation, dissemination and use of ideas, knowledge and, consequently, innovative results the only mechanism that can be the basis for making management decisions. Problems of innovative development of regions are identified: lack or weak involvement in the innovation process of research and scientific organizations capable of creating advanced technologies in demand by the market; insufficient production base for scaling develop-ments, due to high wear and low intensity of modernization of existing production facilities; complexity and opacity of the mechanism of selection and financing of innovative projects, underdeveloped system of tax incentives; problems of involving enterprises in the innovation process due to high risks of unprofitability of investment projects; limited infor-mation on the source of production of innovative goods, services, technologies; Irregularity of statistical data The pres-ence of the listed problems of innovative development of regions leads to the need to expand the understanding of the factors and reserves not involved in modern mechanisms of activation of sources of innovative development of regions.

Kuznietsov","doi":"10.30929/1995-0519.2021.6.60-65","DOIUrl":"https://doi.org/10.30929/1995-0519.2021.6.60-65","url":null,"abstract":"Purpose. To increase the effective volume of stego containers in the FPGA program code. To achieve this purpose, an additional procedure of non-equivalent transformations of FPGA program code is added. Non-equivalent transfor-mations complement the traditional procedure of equivalent transformations of program code. The joint use of these two types of transformations leads to the achievement of the purpose of this paper. Methodology. The steganographic ap-proach is used to covertly embed additional data into the FPGA chip program code. In this case the FPGA program code is a stego container. The stego container embedding procedure is used to perform hidden monitoring of the FPGA program code. For this purpose, monitoring data is embedded into the program code and secretly stored there. The tradi-tional approach to steganographic embedding in FPGA program code is based on the use of equivalent transformations of the program code. Such transformations do not change the target function of the program code or the operation of the FPGA chip. However, the traditional approach provides a relatively small effective volume of the stego container. This leads to the fact that it is usually possible to steganographically store only control data for one type of monitoring. It is proposed to additionally use a non-equivalent approach to steganographic embedding of data into the FPGA program code. Such transformations, despite their non-equivalence, do not change the target function of the program code. This is achieved by applying transformations to the program code of units that perform arithmetic operations on approximate data. For arithmetic operations on approximate data there is often a requirement that the operands and the result are the same size. To satisfy this requirement the complete result of the operation is computed first. After that some bits of the result are discarded and rounding is performed. It is proposed to allocate elementary LUT units in the FPGA structure, which participate only in the calculation of discarded bits (and do not participate in the calculation of the remaining bits). Program codes of such LUTs can be non-equivalently changed during steganographic embedding. Distortion of the FPGA program code of such units does not distort the behavior of the FPGA chip. This is a consequence of the fact that such LUTs are not involved in the formation of the discarded bits. Results. We have developed software that, together with Intel Quartus CAD system, extracts detailed information about an FPGA project. This information includes the structure of the circuit in the project and the program codes of the units of this circuit. An application has also been developed that uses this information to determine non-equivalent steganographic resources. With the help of the devel-oped software, an experimental estimation of the additional volume of the stego container is performed. Originality.

The purpose of this study is to develop sustainable approaches to ensuring environmentally efficient management of the transport network of urbanized areas by assessing the environmental efficiency of the development of bicycle transport networks. Methodology. The development of approaches to ensure environmental safety in the operation and development of transport networks of urbanized areas is based on the methods of analytical analysis of the existing experience in the implementation of such activities and mathematical calculations of the effectiveness of the application of the proposed methods. Results. To assess the environmental efficiency of optimizing the functioning and development of the transport network of cities, criteria were proposed for replacing road transport work with bicycle transport, reducing pollutant emissions and fuel consumption, and reducing acoustic pollution. Based on the results of calculations on the environmental efficiency and the feasibility of developing the cycling transport network of cities on the example of model districts of Kharkov, it was found that the efficiency of developing the cycling transport network in the central region of the city of Kharkov is more than 20 times than in a residential area. It was found that the proposed eco-oriented approach cannot be applied in an unchanged form in practice due to the lack of physical ability to build a bicycle transport network in the central part of the city and the formed area development. Based on the results obtained, it has been established that it is advisable to take into account not only the parameters of road transport operation, but also the development of the city's road network itself in the context of sustainable development.

Improving the heat resistance and corrosion resistance of carbon steels can be achieved by applying to their surface coatings based on molybdenum and silicon, niobium and silicon, vanadium and silicon, chromium and silicon, which form on the surface protective films of oxides. In this work properties of chromosilicide diffusion coatings applied to steel 45 obtained by the gas method are investigated. Methodology. Diffusion chromosilicide coatings were applied to steel 45 by the gas method. The process was carried out for 6 hours in a closed reaction medium at the pressure of the active gas phase (106 Pa) and a temperature of 1323K. In the work wad studied phase and chemical compositions of diffusion coatings. The heat resistance of the coatings was studied in a specially designed shaft furnace. Corrosion tests were performed by massometric method .The electrochemical behavior of steel and coated steel was studied by the method of removing polarization curves on the potentiostat PI-50.1.1. Results. X-ray diffraction layer analysis revealed that the diffusion layer on the surface of steel 45 consists of two zones - the outer (10–15) 10-6 m, which contains chromium carbides Cr23C6 and Cr7C3 and inner (60–80) 10-6 m, which consists of a solid solution of silicon and chromium α-Fe. The total thickness of the coatings is 100 μm. Microhardness – 19.5 GPa. It was found that chromosilicide coatings obtained by the gas method have high heat resistance up to 1000 С. It is shown that diffusion chromosilicide coatings oxidized at temperatures of 700–800С have higher corrosion resistance in various aggressive environments and a more stable passive state than non-oxidized ones. The degree of protection reaches 99,92–99,99%. Based on the research, a new method of diffusion coatings on the surface of carbon steels with subsequent oxidation was proposed. Practical value.

Competence-oriented physical and psychophysiological training in the course of constructive activity passes from disparate processes and systems to a holistic formation with synergetic unity and certainty of structural elements. The ability to understand the educational activities in the discipline of Physical and Psychophysiological Training as a constructive and transformative force motivates the cadet to physical activity, which is correlated with his physical culture and health competencies and the purpose of professional education.
