The concept of quality in the minds of Soviet and Russian people is inextricably linked with the concept of GOST. Requirements, imposed by the standard to quality of production, does not remain constant, but change in accordance with the level of development of science, technology and best practices. The article considers dynamics of changes of requirements of GOST 10632 "Chipboards. Technical conditions" to the quality of chipboards in the last 40 years. The author analyzes the wording of this standard, approved in 1977, 1989, 2007 and 2014. For specified period of time the labeling of the plates P-A and P-B to P1, P2 has changed, which is related to the harmonization with foreign standards. In the last edition of the GOST 2014 plates have no restrictions on size, so as to replace presses periodic action, which have specific dimensions of the heating plates of the press, presses of continuous extrusion come. The same situation is with the densities of boards, the manufacturer sets its value, but the strength of the plates shall conform to the requirements of the standard. Although, strength characteristics (ultimate strength in tension perpendicular to the plate and the ultimate strength in static bending) are reduced with each new edition of GOST. Tightening of the requirements has occurred to the sanitary and hygienic indicators of chipboards. The content of free formaldehyde has decreased from 10 to 4 mg per 100 g of absolutely dry plate. To obtain competitive boards of E0 emission class Russian chemical industry needs to develop a large amount of resins with low content of free formaldehyde.

Growth rates of production of furniture in our country increase every year. And as the statistics, generally due to production of furniture from slabby glued materials, such as a chipboard, fiber board of average density, plywood shows. Apply to an upclassing of a surface of boards of slabby materials most often PVC films, the decorative paper and layered plastic and much less often the planed interline interval and an interline interval began to use a fayn-line. It is connected by that at a veneering a planed interline interval one of defects of a veneering – infiltration of glue on a front surface of a board very often comes to light. Ways of elimination of such defects aren´t present and therefore the spent materials simply are utilized and hit the pocket the producer. To avoid these risks the producer simply refuses use of similar materials. Our research was reduced increasing viscosity of glue and by that to exclude possibility of its infiltration on a front surface. For this purpose we suggest to enter into working solution gluing a filler – grinding dust. Use of grinding dust in the form of a filler at a veneering of boards allows to solve at once some problems: to use at a veneering of boards low-toxic urea-formaldehyde resin (today in production of products from wood generally urea-formaldehyde resin with a carbamide ratio to formaldehyde 1:1.5 are used), to increase durability of pasting of a basis and facing materials, to reduce marriage percent due to infiltration of glue on a front surface. Results of researches showed that it is possible to use low-toxic urea-formaldehyde resin where the filler in the form of grinding dust will be added to a compounding of glues at a veneering of boards. Optimum values of quantity of a filler from the square of infiltration of glue at a front surface and durabilities of gluing of facing layers to a basis were established.

The subject of the research is the approach to the possibility of using business intelligence for integrated data processing and analysis in order to optimize the company’s activities. The purpose of writing this article is to study the concept of the BI-systems peculiarities use as one of the advanced approaches to the pro- cessing and analysis of large data sets that are continuously accumulated from various sources. Methodology. The research methodology is system-structural and comparative analyzes (to study the application of BI-systems in the process of working with large data sets); monograph (the study of various software solutions in the market of business intelligence); economic analysis (when assessing the pos- sibility of using business intelligence systems to strengthen the competitive position of companies). The scientific novelty consists the features of using the business analytics model in modern conditions to optimize the activities of companies through the use of complex information, which in many cases is unstructured, are identified. The main directions of working with big data are disclosed, starting from the stage of collection and storage in specialized repositories, and ending with a comprehensive analysis of information. The main advantages of using dashboards in the process of demonstrating research results are given. A comprehensive analysis of software products in the business intelligence market has been carried out. Conclusions. The use of business intelligence allows companies to optimize their activities by making effective management decisions. The availability of a large number of BI tools al- lows company to adapt the analysis system in accordance with available data and existing needs of the company. Software solutions make it possible to build dash- boards with the settings of the selected system of indicators.

Михайлов ОЦЕНКА ЭФФЕКТИВНОСТИ ХИРУРГИЧЕСКОГО ЛЕЧЕНИЯ ПАЦИЕНТОВ С ЗАСТАРЕЛЫМ РАЗРЫВОМ ПЯТОЧНОГО СУХОЖИЛИЯ С ИММОБИЛИЗАЦИЕЙ КОРОТКОЙ ГИПСОВОЙ ШИНОЙ ФГБНУ «Иркутский научный центр хирургии и травматологии», Иркутск, Россия Повреждения пяточного сухожилия занимают ведущее место среди травм сухожильно-мышечного аппарата. В клинической практике до 58 % составляют застарелые разрывы пяточного сухожилия. В статье приводится клиническое наблюдение оперативного лечения пациента с застарелым разрывом пяточного сухожилия с применением пластики ахиллова сухожилия по Чернавскому при дефектах III степени по Myerson в сочетании с короткой гипсовой иммобилизацией и ранней активизации пациентов, что позволяет сократить период реабилитации пациентов после оперативного лечения. Ключевые слова: пяточное сухожилие, ахиллово сухожилие, пластика по Чернавскому Heel tendon injuries is the most common trauma of tendomuscular apparatus. Old ruptures of heel tendon occur in 58 % of cases in humans. The aim of the research was to estimate the effectiveness of treatment of the patients with old ruptures of heel tendon with Myerson type III defects who had tendon reconstruction on Chernavsky and short plaster splint immobilization of lower extremity for 4 weeks. We operated 10 patients using reconstruction on Chernavsky in our clinic from 2012 to 2014 (average age -47,6 ± 12,0 years, 8 males and 2 females). All patients had old ruptures of heel tendon. Average time from the moment of trauma till the operation was 112,6 ± 80,4 days. Diastasis between the ends of tendon was 5,8 ± 0,7 cm that corresponds to Myerson type III.Average term of staying at hospital was 10 ± 2 days. We didn't register any complications in postoperative period. Term of plaster immobilization of the operated extremity was 4 weeks. AOFAS score was 34,2 ± 6,8 points at the control examination in 1,5 months that corresponds to bad functional result. We registered good functional results (88,6 ± 3,5 points) in 3 months. In 6 months, functional results were 95,9 ± 1,6 points. In 12 months after the operation average score was 97,9 ± 2,1 points that corresponds to excellent functional result. Using heel tendon reconstruction on Chernavsky at the Myerson type III defects in combination with short plaster immobilization and early activization of patients allows to decrease term of rehabilitation of patients after the operation.
