The aim of this article is to indicate how to organize effective training for elder workers and to identify the differences resulting from the type of performed work in this field. Teaching older workers in particular about health and safety in a way that suits them may reduce the number of accidents and occupational diseases. It can also improve the work efficiency of this group and increase their sense of security. Questionnaire study was conducted with the use of a form developed for its needs in order to determine the most optimal way of organized training for employees. The study group consisted of 544 employees aged 50+ (so-called older workers) and such selection  was deliberate. The questionnaires were filled in by employees of companies that agreed to participate in the study.

Assessment of the ability to work is a very important element in terms of return to work, e.g. in regard of persons coming out of illness or accident, and in relation to disabled persons. The assessment should be based on standardized criteria. The article presents a proposal of tools for functional assessment of activities performed simultaneously at numerous workplaces with various body positions, upper limbs, manual and repetitive activities.

The article presents the results of validation of an exemplary 3D structure model created in the Femap program with the use of experimental data collected during mechanical vibration tests on a laboratory stand. The conducted tests were aimed at examining the possibility of creating a numerical model of a 3D structure in the Femap software, reflecting the behaviour of a 3D model subjected to mechanical vibrations, and then using it to predict the results of subsequent tests carried out on modified structures. The vibrations of the 3D structure during excitation with the test signal were recorded with a high-speed camera and then analyzed with the image analysis software MOVIAS Neo. The values of displacements at the measurement points of the examined structure were used to validate the numerical simulation model. Using the definition of material and physical parameters, it was possible to create a numerical model, which was then tested, and the obtained results were compared with the experimental data. This confirmed that the numerical model created in the Femap software could be used to predict vibrations of 3D structures using the finite element method.
