Creation of New Types of Medical Simulation Systems with Feedback and Interactive Guides Using Augmented and Virtual Reality: The Innovative Project

The article considers the features of the use of simulation technologies in distance learning, including in a complex epidemiological situation. The Purpose of the Work: To evaluate the role of simulation technologies in distance learning of senior students of medical universities. The study included 29 6th-year students of the medical institute of the Chechen state university (Grozny, Russia). The introduction of simulation technologies makes it possible to improve the connection of theoretical material with clinical practice, increase interest in learning and self-discipline.

Synthesis and Research of Nanocompositions of Oxide Materials Based on Titanium Dioxide for use as Contrast Agents in Optical Coherence Tomography

In this paper, the contrasting properties of titanium dioxide nanoparticles in various compositions were considered. In the course of the work, methods for the synthesis of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO2 and SiO2-TiO2-ZrO2 were developed;the microstructure of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO(2)was studied;the stability of oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO2 was determined. The elemental composition of the oxide materials SiO2-TiO2, SiO2-ZrO2, TiO2-ZrO(2)and SiO2-TiO2-ZrO2 has also been studied using SEM and XRD methods. It was found that SiO2-TiO2-ZrO2 nanocomposites with content of titanium dioxide from 8 to 9.5 % and zirconium dioxide from 0.5 to 2 % are completely insoluble in a highly alkaline medium. Thus, this composition is the most optimal for use as a contrast agent in optical coherence tomography.
