  Since I have been working I have been in contact with small and medium-sized enterprises (SMEs) and large companies in various ways. I have thus been confronted with the disadvantages of the former in terms of the introduction and use of 4IF technologies.  Yet most of them are aware that to remain competitive in the market, they cannot avoid digitising their operational processes to some extent. I have also found that this mainly depends on the characteristics of the organisation; for example, its orientation. Domestic SMEs are therefore currently at a competitive disadvantage in the market. However, there is no information on whether there is a trend towards development and where they themselves should develop. This would help them to develop the right, achievable vision for the future, coupled with a feasible business strategy.

  The aim of the article is to compare motivation theories from the view of general psychology and work psychology. The research was done by using secondary sources and by analyzing motivation from both views. The difference between the two lines lies in outcome orientation. Psychology is more descriptive work psychology tends to focus on the results of the motivation process. In comparison, both have their values. The relevance of the research is to provide a theoretical basis for improving the development of more relevant motivation theories.

  WEDM technology is among the final technology. It is characterized by the high quality of the machined surface. Therefore, a small geometric deviation from the desired shape, position, orientation or run out may have a significant impact on the functionality of the finished component. Its range is largely influenced by the accuracy of the applied electroerosion device, the precision of the workpiece and tool setting, the machining method, but also the combination of each other and the adjustment of all process parameters. They result in the final quality of the machined surface not only in terms of roughness parameters but also in terms of geometric precision of the machined surface. The aim of the paper was to describe the possibilities of improving the geometrical accuracy of WEDM with thin brass electrodes. At the same time, it contributes to an existing database of knowledge that defines the influence of selected aspects on the geometrical accuracy of the machined area in the production of circular openings.

  The aim of the study is to analyse the kinematics and the workspaces of two parallel manipulators. The kinematics are calculated using vectors and the Newton method. The workspaces are shown using constant orientation. The result of the study is that the kinematics and workspaces are comparable of the two manipulators. MATLAB was used for calculating.
