Statement of the problem. Current requirements for metal construction and road machines should meet the needs of durability and efficiency. Increased power shift forms of working to reduce metal construction, cheaper replacement for the cost of materials lossless bearing properties and other physical and mechanical properties are particularly relevant [1]. Analysis of publications. An analysis of design features improve scraper shows the trend aimed at increasing the efficiency of filling the bucket. It is not the problem of unloading soil with a scraper , which also requires additional energy. Increasing the efficiency of the discharge can be achieved by improving the shape elements bucket design. The aim is to determine the stresses that occur on the back wall scraper in the process of unloading in the changing height of about fixing cylinder. Achieving this goal requires solving problems: – develop model and conduct experimental research on load models rear walls scraper in a changing height mounting over the cylinder; – determining optimal settings back wall scraper. Conclusions: 1. Analiz stress diagrams in CAD Solid Works Simulation and polarization–optical method showed that the traditional design of the rear wall scraper requires improvement in terms of optimal configuration and strength. 2. A new design of the rear wall scraper has a more uniform distribution of stresses reduces the overall intensity by 30–40 % at the location of the cylinder in the ratio = 0,5.

Conditions of stress-strain state development in loess soil in the base and around pile shaft under various cases of collapsible loess soil soaking are studied: a) Soaking from top to bottom which has been established as the basis of the effective normative documents for pile foundations in loess soils based on theoretical and experimental research; b) Collapsible soil body soaking form bottom to top (underground area flooding) which has indicated that stress state of the pile foundation base is expressed by diminishing function. A collapsible loess soil body underground soaking case with piles partially penetrating collapsible soil has indicated that stress redistribution in the soil body under the pile tip and around pile shaft is taking place when pile tips lose their bearing that eventually leads to pile bearing capacity failure and initiation of pile cap contact bearing.

Statement of the problem. Self–realization in the profession of young professionals after graduation is a very important issue. Despite the high intellectual potential and mobility of university graduates they lack employment and life experience, providing with the first workplace in the labor market. The process of the growth level of the unemployed youth has negative economic and social consequences for the population of our country. Up today there are no any labor exchanges for youth or even departments for them in many cities of Ukraine. Youth, university graduates who are found for the first time themselves in the labor market are the most vulnerable of its category. Almost every other of registered with the state employment is a young person aged up to 35 years. Analysis of the literature. Issues of youth labor market, especially those with higher education are covered by such Ukrainian scientists as: S. M. Zlupko, A. A. Jaremenko, A. S. Lavruk ets. The purpose of the article — analysis of the causes of youth unemployment in the present–day Ukrainian labor market, identifying the impact of youth unemployment on the society, the study of the role of education in ensuring a high level of youth employment, the study of the trend work of employment centers associated with youth employment. The main objectives of the study: analysis of organizations activities, institutions that deal with youth employment in modern Ukraine; studying of the causes of the imbalance of the market for educational services and the youth labor market; identifying the key tendencies and problem of youth employment; defining the role of the Public Employment Service regarding youth employment; development of conceptual solutions to improve youth employment. Conclusions. In order to solve the problem of employment of young professionals it is necessary to make the following suggestions: establish centers of employment for young people or departments for youth employment in the state employment centers in all cities of Ukraine and ensure their financial support from the local authorities; it is necessary to adopt the law that would provide for the widespread use of flexible working hours for young people; introduce a clear system of required number of young professionals on the needs of different economy branches and consequently ensure graduates with first workplace; develop a mechanism of financial support to companies involved in the program of youth employment; take into consideration the need for specialists of industry in the region and forming of there should government order for the required specialties.

Important indicator of the quality of life and safety of life of modern man is easy to obtain and use them information. Formation, development and use of the rapidly developing and significantly changing the modern information space makes the actual task of creating the best conditions for its solution in an urban environment. Drastic changes of sources and methods of access to diverse information resources require new organizational, functional, space-planning and design solutions in the existing building typology. One of the areas of practical implementation of the actual problem may be the design and construction of the library. Since this type of building does not yet have any wide application in domestic and foreign practice, it is necessary initially to analyze the functional structure, space-planning and architectural-shaped organization of media centers and their placement techniques in planning the structure of the largest city on the example of Dnepropetrovsk. The main issues related to the design of media centers, identified the main directions for the formation of functional and space-planning structure within the existing architectural and typological features. On the basis of analysis and systematization of materials foreign practice of designing and building media centers identified the main types of "media library", "educational or research center", "information complex media", which differ according to the type of user access to information - outdoor, specialty and limited accordingly. The basic specific features of media centers in modern conditions, allowing to make recommendations and to identify promising directions for their architectural form. The features of the organization of media centers, analyzed the technological and typological features and space–planning features of media centers, as well as factors affecting their architectural solutions. Developed a pilot project of the media center.
