This article views the problem of professional readiness of a future teacher to the professional work. Much attention is given to the contemporary social and economic situation and the increasing role of the system of education. The readiness of a future teacher to the professional work is presented as a system containing such components as motivation, knowledge and skills. The conditions necessary for improvement the training of future teacher to their professional work have been specified.

This article is devoted to the problem of deviant behavior of teenagers; it reveals the influence of external factors on the development of deviations of teenagers and offers to conduct the preventive work in a complex in early stages of development of deviant behavior. The factors and circumstances specifying the demonstration of deviation have revealed. The development of school policy aimed at the organizing the social and pedagogical conditions neutralizing and correcting negative impact of the social crisis has been suggested.

School readiness issues are addressed by educators, psychologists, special education teachers, and physicians. Recently, the law on compulsory school attendance for all children at the age of 6 has been adopted. In this regard, there arises the question whether six-year-old children are ready for school. Will they be able to meet the requirements of school educational program at the proper level, or only by overworking and tiring themselves both physically and psychologically they may adhere to the desired level of education.

The study of the structure of matter is one of the main tasks of chemistry. The problem can be solved with the help of graph theory, which allowed us to find an unexpected way to solve our logical problem. Thus, the aim of our article was to master the theory of graphs for constructing the structural formulas of organic compounds. Prediction of chemical reactions, the possibility of systematization and study of the essence of basic chemical concepts, such as structure, configuration of atoms and molecules, confirmation, isomerism, and, undoubtedly, the quantum-mechanical basis of the interaction of molecules, all this is possible using chemical graphs. Graph theory allows a non-standard way to approach the problem of constructing the structural formulas of molecules of organic compounds.

The article examines modern technologies that contribute to the implementation of creative design ideas, based on the analysis of modern lighting technology and energy saving factors. It is hypothesized that the goal of modern design in this article is defined as the creation of new space and values, through the renewal of the human environment. The basis for confirming this hypothesis should be the justification for the use of lighting technology and electronicsin solving conceptual and artistic design problems. The scientific research is based on the methodology for making design decisions and ways to open new ways for the implementation of creative imagination and new conceptual solutions of the designer, on the example of designing the interior of a cafe. The author considers and substantiates such terms as intelligent space, interior as a process, integrated lighting systems, informatization of interior space, new methods of decoration, etc. Examples of analysis of design situations from are given the point of view of functional tasks, classification of requirements when making design decisions is substantiated. Lighting technologies in the interior are viewed as a tool that solves a whole range of tasks that combine aesthetic and technological principles of interior shaping. Modern technology is seen as a designer's tool that should be used to understand the role of design as a conduit of scientific advances and innovative technologies to the consumer environment.
