This article identifies the main advantages and disadvantages of using VR simulators to improve the professionalism of employees when performing work at an enterprise (organization). An analysis of existing projects used in various industries was carried out. A description of the developed first aid project is presented. The developed simulator allows you to practice skills in eliminating bleeding in different parts of the body: arm, leg, neck. While working on the project, the main factors influencing the quality of the developed VR simulator were identified. Thus, it was found that VR simulators are not capable of fully simulating fine motor skills of the hands. In addition, the simulator has restrictions on the position of the body in space. Despite the identified shortcomings, the use of the simulator allows you to practice key skills in providing first aid.

Keywords: virtual reality, VR simulator, personnel training, professional activity, first aid, information technology, modeling.

Engineering and geological conditions of the reconstructed territories are important town-regulating factors in the development of Master Plans and Rules of land use and development. They should be taken into account both at the pre-investment stage and at the stages of development of preliminary and working projects of construction projects. Data on the degree of exposure to dangerous engineering and geological processes will allow calculating the stress-strain state of the foundation depending on changes in the physical and mechanical properties of the soil, which means making the most effective organizational and technological decisions for the reconstruction of urban development.

Keywords: engineering and geological surveys, dense urban development, reconstructed territories, geoinformation bases, digital substructure, geological risks
