Increasing global competition, globalisation of markets and the global economic downturn encourages the search of ways to maintain the stability and growth of industrial enterprises. Nowadays, when business environment is rapidly changing, enterprises have to increase constantly their competitive advantage. Human resources are crucial in addressing these issues. Motives of human behaviour energy and direct it to a certain direction. Needs, preferences, and interests are by far the strongest reasons for choosing the path of further learning. This article seeks to answer how motivation influences young people to choose a profession and what factors are the most important in this choosing. On the one hand, motivation has explained under structural point of view as a factor or set of reasons. On the other hand, motivation has interpreted as a dynamic phenomenon, process, and mechanism. Development of industrial psychology and especially behaviourism made very big influence on the development of psychological motivation theories since 1990. The field investigation of this psychology is the subject of human behaviour in the choosing of the studies. One or another treatment is depending on environmental conditions. A survey reveals that in order to motivate a person, it is necessary to enable them to meet theirs basic needs in such a way that helps achieving the objectives of all institution. The article also presents the most important criteria influencing the choice and their relative weight. The results of the research carried out by the authors have compared with the results of similar investigations by other authors. There are focused on the main factors encouraging choosing particular higher education institution and studies at it. Based on the results of the research, it was made these conclusions. A survey showed that two factors are most important when students are choosing to study. These factors are the desire to acquire higher education and the desired specialty, as well as the personal desire to develop, expand knowledge, achieve the goal. 57 % of respondents indicated that opinions of parents, relatives, friends or teachers were not relevant to them. When it comes to choosing a higher education institution, the most important are the city were person wants to study and where the institution is located, higher education institution prestige and quality of the studies.

In the practice of processing of metals by cutting it is necessary to overcome the vibration of the cutting tool, the processed detail and units of the machine tool. These vibrations in many cases are an obstacle to increase the productivity and quality of treatment of details on metal-cutting machine tools. Vibration at cutting of metals is a very diverse phenomenon due to both it’s nature and the form of oscillatory motion. The most general classification of vibrations at cutting is a division them into forced vibration and autovibrations. The most difficult to remove and poorly investigated are the autovibrations, i.e. vibrations arising at the absence of external periodic forces. The autovibrations, stipulated by the process of cutting on metalcutting machine are of two types: the low-frequency autovibrations and high-frequency autovibrations. When the low-frequency autovibration there appear, the cutting process ought to be terminated and the cause of the vibrations eliminated. Otherwise, there is a danger of a break of both machine and tool. In the case of high-frequency vibration the machine operates apparently quiently, but the processed surface feature small-sized roughness. The frequency of autovibrations can reach 5000 Hz and more.

We performed a case control study to evaluate risk factors for preterm labour in 1200 women. 600 women who delivered prematurely and randomly selected group of 600 women who gave birth at term were questioned using a standardised questionnaire. Simple data analysis, multiple regression analysis, including logit and probit regression models and multiple stepwise regression were performed to identify independent risk factor of preterm labour. Based on this analysis and in respect of these independent factors an equation was suggested which allows to evaluate mathematically risk for preterm labour and can be used in gynaecologists’ practice.
