Introduction. One of the leading causes of occupational health loss, especially in mining and machine-building enterprises, is the combined impact of industrial noise and vibration. The wide prevalence of cardiovascular diseases is one of the most important medical and social problems, due to persistent disability and high mortality, bringing prevention of health disorders to the first place as the basis for preserving labor longevity. The aim of study is to identify the main approaches aimed at preventing health problems in workers who come into contact with vibration and noise at mining and machine-building enterprises. Materials and methods. A survey and survey of 296 industrial workers was conducted. Group 1 (160 people) included men who were exposed to noise and vibration factors above the maximum permissible levels, group 2 consisted of 136 men who did not have direct contact with noise and vibration generating equipment. When conducting an in-depth laboratory and instrumental examination in a hospital setting, all workers additionally calculated the level of cardiovascular risk on the SCORE scale. Statistical analysis was performed using the software package "Statistica 6.0". Results. It is determined that the priority adverse factors of the working environment in production are noise and vibration. It has been shown that individuals who come into contact with these factors are more likely to detect violations of lipid metabolism and endothelial function, have a higher average heart rate and systolic blood pressure, and have an increased risk of developing cardiovascular diseases. Conclusions. Taking into account the obtained results of the proposed diagnostic approaches aimed at the prevention of health disorders among workers of industrial enterprises. If employees are found to have an increased cardiovascular risk, it is necessary to conduct a more in-depth examination and timely medical and preventive measures.

While the development of the country's national innovation system as a whole is very important and should be prioritized, its regional aspect is even more important. The specifics of the Russian Federation's transition to an innovation-based economy is in that that, at the present time, prioritized is the need to ensure the effective development of those economy sectors that underlie the country's specialization and may provide regional and national competitive advantages. To such sectors belong the chemical industry, machine-building and power energetics. We would like to note that initial innovation awareness indicators in the regions are comparable and do not differ greatly but the growth of activity can be observed only in some of the regions. The problem of large differentiation among the constituent entities of the Russian Federation by their level of economic development remains important and has to be dealt with.

The scientific research works concerning the field of mechanical engineering such as, manufacturing machine slate, soil tillage, sowing and harvesting based on the requirements for the implementation of agrotechnical measures for the cultivation of plants in its transportation, through the development of mastering new types of high-performance and energy-saving machines in manufacturing machine slate, creation of multifunctional machines, allowing simultaneous soil cultivation, by means of several planting operations, integration of agricultural machine designs are taken into account in manufacturing of the local universal tractor designed basing on high ergonomic indicators. For this reason, this article explores the use of case studies in teaching agricultural terminology by means analyzing the researches in machine building. Case study method was firstly used in 1870 in Harvard University of Law School in the United States. Also in the article, we give the examples of agricultural machine-building terms, teaching terminology and case methods, case study process and case studies method itself. The research works in the field of mechanical engineering and the use of case studies in teaching terminology have also been analyzed. In addition, the requirements for the development of case study tasks are given in their practical didactic nature. We also give case study models that allow us analyzing and evaluating students' activities.
