    The article is devoted to solving the problem of biodiversity conservation in the framework of increasing sustainability of natural plant communities in arboretum being an artificial protected area. Research and application have accumulated significant knowledge on various aspects of the above problem, specifically, preserving biodiversity including vegetation, monitoring biodiversity and preserving phytocenosis, plant interaction in phytocenosis, causes of disturbed biodiversity and reducing phytocenosis stability, etc. The research objective is to theorize the frameworks for phytocenosis formation, identify the factors influencing phytocenosis stability, conduct observations and experimental research on the factors affecting the formation and stability of the Kurgan regional arboretum phytocenosis. The models of the way different factors influence the resistance mechanisms of the Kurgan regional arboretum phytocenosis are built as a result of studying research materials and differ from the theoretical model in the fact that the proven distinctions were found in the ratio of limiting and background factors reflecting their regional character

    Purpose of the study: Analysis and evaluation of technical and operational risks of flexible endoscopes reprocessing. Materials and methods: Statistical 2016-18yy data of technical and chemicals reprocessing endoscopy rooms equipment and partially data of endoscopes technical service and repairing of Sverdlovsk regional medical facilities have been analyzed. Mathematical analysis has been performed with universal multiply sectioned Bayesian network. Results: Analysis of availability of equipment and chemical consumables evaluated that 85% of endoscopic units use manual reprocessing, which with careful competent approach shows relatively small (22,75%) technical operational risk. Most endoscopy units - 89%, use non enzymatic cleaning solutions and evaluate middle close to high (49,94%) technical operational risk due to potential fixation of micro residual organics, when aldehydes are using for high level disinfection leading for biofilms, which evidently (evidence level A) can destroy endoscopic channels. Aldehyde sare using in 82% endoscopy units, oxygen containing agents based on peracetic acid in 18%. It can be considered as relatively small (24,3%) technical operational risk if use after proper cleaning and exposure modes compliance. Conclusion: Generalized flexible endoscopes reprocessing technical operational risk can be evaluated by analysis of three main criteria: method - manual or automatic, processing chemicals - for cleaning: enzymatic or nonenzymatic, for high level disinfection: aldehydes or oxygen peracetic acid based solutions. Considered risk can be reduced from middle to small (25% and lower) by enzymatic cleaning solutions priority use.ЦСль исслСдования: ΠŸΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Ρ‚ΡŒ ΠΈ ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ Ρ‚Π΅Ρ…Π½ΠΈΠΊΠΎ-эксплуатационныС риски, связанныС с ΠΎΠ±Ρ€Π°Π±ΠΎΡ‚ΠΊΠΎΠΉ Π³ΠΈΠ±ΠΊΠΈΡ… эндоскопов.
