Letter to the editorial office
The authors are grateful to the editorial staff of journal and the reviewer for a positive assessment of the results of our research, and also for comments and suggestions to improve it`s content and design. We send for consideration the text of the revised version of the article, which takes into account the suggestions of the reviewer.
Namely:

1. 
   In the text of the article a section of “Methods and objects of research” is designated with appropriate exposition of it`s content.
   
2. 
   Tables are optimized, namely 1 table is completely excluded, and the other excluded date from duplicate other tables
   
3. 
   What with the absence of the need for the results of questionnaires of the surveyed, information about them is not provided in the article.
   
4. 
   The text of the article is corrected and edited stylistically and grammatically
   

With respect authors
