The relevance of this work is supported by the need to ensure the professional training compliance with both formal and informal requirements of the education system and the labour market. A lack of methods and technologies being able to harmonize the outcome of the information technologies curriculum and the labour market demands is the reason why the university graduates find it difficult to compete on the labour market. The paper describes the method for an ontological model development that would be able to form the content of the IT-competencies and to assess them in the university students. It is based on two thesis: the first, the boundaries of the subject area of competencies should be defined and, the second, a method of taking into account individual characteristics and needs for creation of an individual professional training and self-study plan should be preliminary considered and developed. The article presents the ontological model developed by the stated method to form the content of the IT-competencies and to assess them for the case of the subject area of 1C: Enterprise platform business solutions. The knowledge base created by the ontological model can be integrated into the decision-making intelligence information systems intended for the sphere of education, corporate training and HR management. This article is aimed at the professionals developing new tools and methods for management of distance education and distance learning.

This article reviews the experience of application of VR-AR technologies (virtual and augmented reality technologies) for visual demonstration of production facilities in the process of engineering and operation. The three-dimensional modeling in CAD systems is commonly used as a means for development of construction documentation, visualization of work at different stages of engineering, and preparation of objects for engineering analysis. The authors believe that the use of AR-solutions not in parallel, but along with modern CAD systems for solution of engineering and design problems would allow avoiding design flaws and simplify the process of demonstration of projects. Based on the blueprints and three-dimensional models of the parts and assembly of two-stage reduction gear used  for lifting a thermal furnace in metallurgical production, within the framework of development of the Unity multimedia application is developed the AR application for visual demonstration of the device. As the guide mark for visualization is selected the assembly drawing of the reduction gear in digital graphical format edited in the Vuforia portal. The guide mark database is imported into the Unity environment, the logic of implementation of the technique for demonstrating the assembly of the device and separate parts is written in script program. The application is installed on a smartphone and tested; pointing the camera at the printed assembly drawing allows seeing the 3D model of the reduction gear from different angles, hide any details and scrutinize the device. The AR-applications developed according to the proposed method can be used in the process of training operational personnel, which would improve the performance and quality of work during installation and maintenance of industrial facilities, as well as for displaying the projects during exhibitions and presentations of new products.
