This article provides a critical analysis of the achievements of human development towards sustainable development in the 17th Global Goals and reveals new approaches to the management of this process. Because these goals are related, the success in achieving one of them affects the success of the entire set of goals. This made it possible to distinguish the most acute globalization problems that have require urgent collective attention and special consolidated mechanisms to solve them. It is necessary to establish a unified global system of data collection on indicators of sustainable development from all countries of the world in order to achieve the fundamental social and economic transformations in 2030. The authors identify a new paradigm for the management of sustainable development in the form of governance in the process of achieving the 17 Global Millennium Goals, which aims to provide making such strategic decisions that would serve global interests, and national efforts are supported by effective interstate cooperation through diplomacy and crisis prevention. The researchers generalized the main challenges and suggested to identify the relationships between existing problems of human activity more effectively, adopting an integrated approach and increasing significantly investments in poverty alleviation, inequality and climate change.

Presented a method for calculating the dynamic tangential stresses around the wellbore, at the time of its treatment by the hydraulic pulse generator, by the values of its characteristics, obtained at the bench test, and the frequency coefficients of influence. Criteria are formulated for selecting the natural frequencies of the measuring sensors that ensure the coincidence of voltages in the array and on the measuring bench.

The article is revealed essence and the concept of “ecological and evolutionary approach”, conceptual ideas of ecological and evolutionary approach (the idea of evolution and the idea of ecocentrism) are disclosed. Author determined methodological principles of ecological and evolutionary approach to teaching. The concept of teaching natural sciences on the basis of ecological and evolutionary approach and didactic principles of implementation of ecological and evolutionary approach to the teaching of natural sciences (didactic conditions, principles and laws) are developed and scientifically substantiated which is visualized in a didactic model of teaching natural science on the basis of ecological and evolutionary approach. The technology of teaching biology based on ecological and evolutionary approach is developed. Results of pedagogical experiment proved the effectiveness of the technology of teaching biology on the basis of ecological and evolutionary approach and the conception and implementation of teaching principles of ecological and evolutionary approach to the teaching of natural sciences embodied in it.

The study of flooding gas condensate reservoirs at different stages of depletion (25, 50, 75% of the dew point pressure and at the maximum condensation pressure) with different potential hydrocarbon content of 100, 300 and 500 g/m3 and different voidage replacement by using injection (50, 100 and 150%). The results showed a positive effect of water injection on the increase of the condensate recovery factor, but a decrease in gas production compared to the basic options of development at depletion drive. Thus, for formation systems with medium and high potential yield of liquid hydrocarbons C5+, the largest incremental production is obtained in the case when water injection begins with minimum depletion of formation energy. While for a formation system with a low potential yield (100 g/m3) the maximum technological effect is obtained under the condition of maximum depletion. In the case of medium and high C5+ yield in the formation gas, with a slight decrease in the formation pressure by 25 or 50% of the dew point pressure, the maximum increase in the condensate recovery factor is achieved at high injection rates with 100 or 150% voidage replacement. The obtained results can be used for rapid screening of potential methods of impact on the gas condensate reservoir, and the final decision concerning the technological parameters of production and injection wells operation will be made due to the results of optimization of multivariate hydrodynamic calculations using geological and technological models.

The article considers the sustainable development of the city public spaces and the penitentiary complexes problems from the Synergetics and Socionics standpoint. These approaches provide consideration of the opposite processes of public spaces socialization and correctional complexes resocialization, sustainability, and dynamism its organization, and self-organization. The regularities of sustainable development are present in the cyclical nature of historical changes in public spaces and the penitentiary system. Cycles unfold in the alternation order of pairwise polarized processes, on the one hand, dispersion and concentration, and, on the other, – self-organization and adaptation. We have found that the interaction of universal processes and the natural change of cycles stimulates, on the one hand, growth and stabilization, and, on the other, – transformation and metamorphosis, which lead to the emergence of new forms and structures of public spaces and penitentiary complexes. We have proposed to use Socionical methods for increasing tolerance and democracy in the architectural environment of settlements. We have described the methodological tools to achieve the harmonization of the architectural environment of settlements.

The article justifies technical and organizational solutions aimed at improving the operational properties of hoisting equipment, the development of methods and means of controlling the operational state of existing systems in complex mining-geological and mining-engineering conditions. Technical solutions of a new type of hoisting machines with two consecutive friction pulleys, which have significantly higher load characteristics and allow usage of less metal-intensive and energy-intensive hoisting machines, are considered. The order of estimation of a state of a mine shaft and general types of work on its monitoring are justified. Conceptual foundations of intensification of mining operations in the mines of Ukraine are defined based on modernization of hoisting equipment units and improvement of a control system.

The article is devoted to determining the features of the shadow economy's impact on financial security. For this purpose the following are carried out: generalization of calculation indicators in the shadow economy; influence assessment level of the shadow economy on the volume of gross domestic product (further-GDP); based matrix paired correlation coefficients integral indicator of financial security and factors of shadow economy by various methods; conducted surveillance on the dynamics of the integral index of financial security and the level of the shadow economy, calculated using monetary means and integral measure of financial security of cash in UAH and the dollar; investigated the interconnection statistical indicators and indicators of financial security dynamics of cash in the economy; evaluated the safety performance of non-banking financial market and the volume of cash in dollar terms in dynamics; Then a matrix construction paired correlation coefficients tax rate component of financial security and the coefficients of the shadow economy, estimated by different methodological approaches; monitored security tax rate and share of loss-making enterprises and statistical significance is estimated regression equation pair of security and tax number of unprofitable enterprises.

The mechanism of mountain forming is based on the phenomenon of the formation of compressive normal horizontal stresses exceeding gravitational. These stresses are due to contact friction between the layers of rocks. To reveal the mechanism of mountain forming, the vector method of the body equilibrium on the path of maximum effective tangential stresses of a triangular element is used, taking into account the external and internal forces acting on it. It is shown that the total vector of these forces, taking into account internal and contact friction, is directed against the gravitational force and generates mountain forming. A generalization of experimental observations on the elevation of rock structures and anomalous manifestations of rock pressure is given.
