THE YOUTH’S PERCEPTION OF RELIGIOUS VALUES: A SOCIOLOGICAL STUDY

The article considers the younger generations’ perception of religion and the role of religious values. The authors argue that in the last decades the attitudes to religion in the Russian society have transformed. Religion determines values of every culture that influence the worldview of different generations. In the contemporary secularized society, religion plays the role of a moral referee, forms a national mentality and a worldview. Younger generations as a dynamic social group do not tend to follow conservative traditional values, which allows to understand further trajectories of social development. The youth’s interpretation of key life values significantly differs from the understanding of the same values by older generations. Younger generations are usually characterized by social dynamism, psychological lability, changing perception of cultural traditions and values, constant search for innovations and revision of the established traditions. Religious values are traditional and conservative by nature, thus they turn people to the past rather than to the future, that is why the youth is often unclear about religion. The data of international and Russian surveys prove that the youth consider religion quite pragmatically, as a kind of psychotherapy. The article presents the results of the sociological research, in which religious values were compared with other cultural values - artistic, scientific, moral and practical. According to the data, the number of people interested in religion and faith issues has significantly increased compared with the late Soviet period but religious values for younger generations are not a priority for other cultural values seem to be more important

Novel Biocompatible with Animal Cells Composite Material Based on Organosilicon Polymers and Fullerenes with Light-Induced Bacteriostatic Properties

A technology for producing a nanocomposite based on the borsiloxane polymer and chemically unmodified fullerenes has been developed. Nanocomposites containing 0.001, 0.01, and 0.1 wt% fullerene molecules have been created. It has been shown that the nanocomposite with any content of fullerene molecules did not lose the main rheological properties of borsiloxane and is capable of structural self-healing. The resulting nanomaterial is capable of generating reactive oxygen species (ROS) such as hydrogen peroxide and hydroxyl radicals in light. The rate of ROS generation increases with an increase in the concentration of fullerene molecules. In the absence of light, the nanocomposite exhibits antioxidant properties. The severity of antioxidant properties is also associated with the concentration of fullerene molecules in the polymer. It has been shown that the nanocomposite upon exposure to visible light leads to the formation of long-lived reactive protein species, and is also the reason for the appearance of such a key biomarker of oxidative stress as 8-oxoguanine in DNA. The intensity of the process increases with an increase in the concentration of fullerene molecules. In the dark, the polymer exhibits weak protective properties. It was found that under the action of light, the nanocomposite exhibits significant bacteriostatic properties, and the severity of these properties depends on the concentration of fullerene molecules. Moreover, it was found that bacterial cells adhere to the surfaces of the nanocomposite, and the nanocomposite can detach bacterial cells not only from the surfaces, but also from wetted substrates. The ability to capture bacterial cells is primarily associated with the properties of the polymer; they are weakly affected by both visible light and fullerene molecules. The nanocomposite is non-toxic to eukaryotic cells, the surface of the nanocomposite is suitable for eukaryotic cells for colonization. Due to the combination of self-healing properties, low cytotoxicity, and the presence of bacteriostatic properties, the nanocomposite can be used as a reusable dry disinfectant, as well as a material used in prosthetics
