The article presents results of studies of changes in the parameters of shoe last footstep of women's shoes with a particularly high heel. The benchmark analysis of experimental and theoretical data of the change in the amount of shoe last (insole) footstep shear of the shoe in the heel part is made. The shear depends on shoe size and pitch. It is found that the value of the insole shear in the heel part in the series varies insignificantly when the pitch remains unchanged. An increase in the height of the heel part elevation of the shoe increases the insole shear in the extreme dimensions of the series by 5–6 mm. In the series of shoe lasts of high-heeled shoes, the insole shear is 9–11 mm. The constant value of functional allowance set by GOST for shoe lasts in the toe part violates the basic principle of grading, the principle of similarity, which can lead to the fact that in shoes with extra high heels the length of the shoe last footstep will be less than the length of the foot, which is not permissible. The research detected such cases in practice, which proves the need to increase the size of the functional allowance in shoes with extra high heels. The suggestion is made to introduce a system of footwear numbering uniform for all countries, taking into account the wide development of Internet commerce.

The article discusses the possibility of analysis of the degree of floor carpet wear by their reflectivity indicators. It is shown that the wear of floor carpets considerably changes their optical properties. By analyzing these properties, there is a possibility of an adequate assessment of the quality of carpets after a certain usage period. The work presents the abovementioned technique of using the standard photoblocker and a method to construct a luminous portrait of the carpet, which is an assessment of the reflectivity uniformity of carpet surface area.

The subject of the investigation is the determination of forces effecting the cutter during shoe materials cutting with an analytical method. The research is being carried out to improve the accuracy of the design of tooling for a sewing semi-automatic machine. Determination of forces affecting the cutter during shoe materials cutting is done applying analytical method which is based on the representation of forces as functions of the relative deformation of material, numerical integration of these functions, and compilation of a program for determination of these forces. Using experimentally obtained data a technique is developed for the analysis of forces affecting the cutter during shoe materials cutting.

The aim of the work is to study the features of the formation of a knitwear three-dimensional structure, including those made using multifilament yarns. Experimental samples of products are made. The peculiarities of the structure of high-volume knitted garments of plush interlacing made of multifilament polyester yarns of JSC "Svetlogorsk Khimvolokno" are investigated. The expediency of using multi-filament yarns produced by JSC "SvetlogorskKhimvolokno" for manufacturing high-volume knitted garments is established.

The work investigated the possibility of combining the antibacterial treatment with the process of dyeing fabrics, containing polyester fibers, using triclosan. A feature of the chosen biocide is its ability to plasticize the polyester structure and facilitate dye diffusion, which will allow to lower the dyeing temperature of 30–40 °C (to 100 °C) or at high temperature dyeing decrease the consumption of the dye due to its greater selectability. It is shown that by using the triclosan color intensity increases while color stability persists. The fact of obtaining antibacterial properties is proved. Triclosan can not only provide a reduction in energy consumption during dyeing but also eliminate the antibacterial treatment at final finishing step. It can be recommended for the dyeing of fabrics that contain polyester fibers.

The paper describes the criteria of assessment the environmental risk of oil products con-taminate not only for individual water bodies, but also for individual territories, including admin-istrative region and areas where data will be used to compare the environmental load. The aim of the work is to assess the environmental risk of pollution of water bodies in the Vitebsk region with oil products. The catchment areas of the Western Dvina River in the Polotsk and Braslav districts were chosen as a research object. In the developed model, the calculation is made according to four blocks of factors: a block of technogenic factors, a block of natural factors, a block of anthropogenic factors, and a block of factors that depend on the time of the year. A total of 20 criteria have been developed, divided into four blocks of factors.

Such a form of housing stock management as an owners’ association is now distributed in the Republic of Belarus. The effectiveness of the activities of the owners' associations attracts the increased attention of various users. At the same time, economic science and practice does not have a systemic integrated approach to assessing the effectiveness of functioning these organizational and legal forms of organizations. The aim of the study was to develop an integrated methodology for assessing the effectiveness of owners’ associations from the point of view of all stakeholders – state, population and directly the association itself as an institutional unit of the national economy. In this paper, the authors proposed an integrated assessment to assessing the effectiveness of activities of owners’ associations, in which frameworks such concepts as "economic effectiveness", "social efficiency", "budget efficiency". From the point of view of economic effectiveness, the activities of the owners’ associations will be effective if the maintenance costs are fully reimbursed by the revenues received. Consequently, the economic effectiveness for owners’ associations is the ratio of the income received and expenses related to the maintenance of an apartment house. On the other hand, the owners’ associations are called upon to meet the needs of the population to the greatest extent. Social efficiency is defined as the correspondence of the results of the economic activities of the owners’ associations to the basic social needs and goals of society, to the interests of the individual. Taking into account that the owners’ associations receive budget subsidies as a reimbursement of part of the maintenance and housing maintenance costs, one can not ignore the budgetary component of the evaluation of the effectiveness of their activities, which can be defined as an indicator of the budget burden as a result of the participation of budget subsidies in the formation of the income of the owners’ associations. The developed indicators on all aspects of the effectiveness assessment make it possible to comprehensively analyze the activity of the owners' associations and determine the reserves for improving the efficiency of the functioning of such organizations. For the generalized estimation of efficiency, an integral coefficient is developed and variants of its interpretation are proposed under different conditions.

The article is devoted to the research of theoretical and analytical approaches to the formation of tax environment. The definitions of tax environment as well as factors that influence it are studied. The main elements and system indicators of tax environment (structure of tax system, tax burden, dynamics of taxpayers, satisfaction with tax services quality) are analyzed. It’s justified that modernization of tax administration in the direction of the improvement of tax environment quality should be focused on the strengthening of the interaction with taxpayers. The conclusions about the improvement of tax environment quality are made.
