The article discusses the formation of a new approach to the statutory regulation of 3D printing, an uncommon object of civil matters. Creating a product with the help of such technology not only by an entrepreneur but also by any person, can in practice cause some issues in protecting all participants’ rights during the 3D printing process. 3D printing is regarded as a complex object, so its characteristics are determined. Additionally, possible ways of resolving legislative gaps are proposed, such as: defining the concept of the manufacturer, supplier, seller, and consumer of 3D printed products; developing their rights and responsibilities; establishing quality requirements for 3D printed elements; and adopting clear rules on liability and consumer protection. Due to the widespread use of digital technologies, Russian legislation requires a thorough reconsideration and early reform.

The need to create favorable conditions in schools to support gifted and talented students is due to the social order and humanistic paradigm of modern education. This article deals with the problem of developing personal qualities of students in the framework of pedagogical support for students with signs of giftedness in the modern school. The article reveals the results of the study of personal development of students accompanied by teachers in the process of designing and implementing individual educational routes at the main stage of general education. The leading method of studying this problem is the analysis of the results of the survey of teachers and schoolchildren in order to determine changes in the manifestation and development of personal qualities of students with signs of giftedness, accompanied by teachers, in the process of implementing their individual educational path using the model of the educational route developed by the authors of the article. The summary of the research presented in the article is the development and testing the structural-functional model of individual educational route for students with signs of giftedness, the use of which contributes to the manifestation and development of personal qualities of students required for the development of their potential and achieving educational outcomes. The materials of the article are of practical value for teachers when planning individual work at school.

The foundations of efficient production are laid at the stage of developing a high-tech product. The object of research is wild berries (lingonberry, honeysuckle, viburnum, cranberry, cloudberry, sea buckthorn, mountain ash, aronia), which are used as a source of a natural complex of biologically active substances and trace elements as the main substance of a new parapharmaceutical. The primary technological task of food engineering of paramarceuticals is the maximum extraction of biologically active substances of plant raw materials and their preservation in their native form during the warranty period of storage. Therefore, as the main criterion for changing the properties of raw materials during processing, we used the amount of change in the redox potential of the system. A set of methodological approaches has been developed to ensure the quality and safety of the new parapharmaceutical.

The article analyzes the research results of a number of analytical agencies regarding the growth rate and key problems associated with the introduction of the “Internet of things” (IoT) in the agricultural economy. The issues of the development of the agro-industrial complex in the context of the development of the digital economy, the experience of introducing the digital economy in the agricultural sector of developed countries and the possibilities of its application in agriculture in Russia are considered. The authors focuses on the positive aspects of the influence of the “Internet of things” on the functioning and development of modern agricultural markets at the macro and micro levels, and the change in the professional structure of the agricultural industry

The article studies process of optimization of cost management structure for improving quality of constructional works in apartment. Property owner has the right to demand the apartment quality during the warranty period. Article 756 of the Civil code of the Russian Federation indicates the limit warranty period as 5 years. Constructional defects can be divided into two categories: general construction and engineering system defects. There are 3 methods, which are applicable to the assessment of apartment quality: ABC, target-costing and life-cycle cost analysis. It is essential to identify the parameters, which can decrease service costs and quantity of defects. Three models of apartment with different conditions are compared. Considering such parameters as the number of defects, the presence of delay in the execution of application, financial loss, presence of repeated complaint from owner, the formula of quality assessment is proposed. New equation allows assessing the quality of the apartment and defining variables, which can influence on it.

On the example of a typical residential multi-apartment building, a feasibility study was carried out on the choice of energy-saving measures for the thermal insulation of facades. The decision to increase the energy efficiency of the building was made on the basis of calculating the loss of thermal energy through the external walls. Based on the parameters of the heating period, capital costs for additional thermal insulation of facades and calculated values of operating costs for heating, the optimum thickness of the additional layer of insulation is determined, in which the payback period assumes a minimum value.
