“…Recently, there have been a lot of disputes about work of student self-management. Systematically conducting an electronic survey among students, we came to the conclusion that the majority of students believe that selfgovernment plays a large role in their development as professionals and there is a need for its constant updating and improvement in accordance with the requirements of modernity [21]. Table 1 reflects the questions answered by students from several colleges in the country.…”

Now the aim of the formation of a competent and competitive graduate who is able to adapt to rapidly changing conditions is the main aim because there are lots of innovations in the sphere of education. Educational institutions solve the tasks using all resources. The authors underline professional competencies development can happen both in studying and in other forms at any time. The authors reveal the essence of the growth of student self-management in college as an effective way of necessary competencies evolution. It is noted that self-management at college transforms the traditional system of interaction between the administration and the learners "teacher-student", turning it into a partnership, where the administration acts as a senior partnercoach, which contributes to the more effective development of graduates' competences. However, the development of conditions for student government should be fairly systematized, so the authors proposed a special model for the development of student self-management in college.

“…The theory of mechanisms and machines (TMM) is based on fundamental knowledge in the study of mathematics, physics, theoretical mechanics and is the basis for the study of subsequent practical (special) disciplines. The main issues that TMM is studying include: -study of the structure (structure) of mechanisms; -determination of the positions of mechanisms and trajectories described by individual points; -determination of speeds and accelerations of individual points; -analysis and design of various mechanisms (gear, cam); -determination of different forces (external, reactions, friction, inertia) acting on the mechanism; -the study of the energy balance of machines (efficiency); -the study of the actual law of motion of machines under the action of given forces; -the study of ways to control the speed of the machine; -the study of methods of balancing the forces of inertia in machines, etc [2]. Thus, we can say that the theory of mechanisms and machines is a science that studies the structure, kinematics and dynamics of mechanisms and machines.…”

Innovative technologies in the construction industry today have widely taken a confident position in the construction industry. The article discusses new technologies used in the work to strengthen the foundations of various kinds. A study was conducted on the application of the traditional way of strengthening foundations and indicators of the use of new technologies. Traditional options for strengthening the foundations associated with increasing the area of the sole are considered from the standpoint of geotechnics and manufacturability in relation to weak waters with saturated soils. The technological characteristics of the results of new technologies during the work on strengthening the foundations are given.

Based on the analysis of quality factors of calibrated rolled products, the structural and mechanical properties of steel 20Mn2Si for cold heading of hardware products are formed. The balance is established during the preparation of gauged bars to manufacture fasteners from it. To produce gauged bars with a diameter of 7.75 mm, a new technological flow is proposed using hot rolled products with a diameter of 8.5 mm. The proposed resource-saving technology for preparing rolled steel 20Mn2Si excludes spheroidize annealing, which reduces labor and energy costs, increases the environmental friendliness of production and operational reliability of fasteners. This eliminates the possibility of quenching cracks, the need for straightening products, the risk of thread defects and reduces the cost of manufacturing long bolts. This makes it possible to significantly reduce the process chain, reduce the cost of manufacturing fasteners and meet regulatory requirements for their mechanical properties.
