The term “coevolution” is used for identification of mutually conditioned elements alterations, acting as an integral system. Development is the vector of these changes. Thus, the coevolutionary approach makes it possible to study the natural mechanisms of the living systems complication. The authors follow mainly this methodological orientation, exploring cultural interaction and environment, in other words – coevolution way. Coevolutionary approach, without denying deterministic character of living systems development, pays special attention to occasionalities, which are considered to be the irremovable factors. Since the mechanism of the origin and coordination of the elements interaction involves occasionality, the system development takes an emergent character. This approach concludes the fact that acceptation of uncertainty factor does not influence the result of the particles joint variability – the variability forms are more productive methods of the entire elements collaboration. Historically developing images of cultures are viewed as the result of coevolution – on the one hand, as the interaction of cultures leading to mutual enrichment, on the other, in the context of natural environmental conditions that form some of their unique features. Coevolutionary methodology demonstrates a theoretical resource that explains the unity and difference of cultures, their transformation. The historical context of the cultures dialogue is presented as a coevolutionary process, the modern mechanisms of which promote convergence and integration of cultures, which replace the process of their evolutionary differentiation – divergence.

The Eastern Black sea region has been developing independently for more than four centuries, within this period the culture of this territory has changed, that has led to a change in intercultural interaction. In today's globally competitive and more peaceful condition of existence, there is a need for constructive dialogue between neighbors, which leads to the need for a better understanding of each of the parties. Comparative culturology can help to determine the differences and common points of contact of the peoples of the eastern Black Sea region, which will open the door for deep, lasting and long-term relations between the cultures and people of Georgia, Abkhazia and the Krasnodar territory of Russia. The aim of the study is to reveal the cultural background on the basis of which these people can interact and determine if there are positive prospects for joint interaction in various spheres of culture. To achieve these goals, several research steps have been carried out, in particular, they include: the definition of comparative study as a term and as a scientific basis for research; comparison of the declared cultures from a non-verbal point of view; providing data on the multilateral distribution of languages ​​in neighboring areas; analysis of the traditional aspect of cultures of Georgia, Abkhazia and the Krasnodar territory of Russia. The final part of the study shows promising results on today's and future cultural interaction in the region of the eastern coast of the Black Sea.

It is considered adaptation ways of religious traditions in the contemporary Russian society, which is characterized by powerful processes of globalization, social and cultural transformations. Three adaptation ways are stated in the article: modernization, conservation, archaization. Adaptation through modernization is expressed in “modernizing” the tradition: justifying its value for modern society, minimizing, but not denying the importance of those doctrinal principles that come into conflict with the new conditions of social life, the accentuation of those aspects of the doctrine that are consistent with these conditions. Religious cult is the main resource of adaptation through conservation. Other ways of conservation lie in a tie of a traditional religion with national self-consciousness and ethnic identity. Identification makes one turn to the religious tradition. Fundamentalism, social reality perception in strong dual system, “tribal” consciousness, when inclusion in some society is perceived as necessity to resist  to the other societies, are considered to be the manifestation of archaization processes in religious traditions. It is stated that modernization, conservation and archaization form a contradiction unity in religious traditions. Religion adaptation towards conditions of the modern society is not possible through a single way; and one way insignificantly prevails over the others. A situation when one of them has obvious domination is a situation of tradition destruction as a result of transformations. Domination of modernization leads to essential transformations of dogmatic consciousness and destroys confessional tradition. Archaization opens access for fundamentalism, which is a ground for radical religious groups. Domination of conservation leads to stagnation, breaking of adaptation processes, then – to reformation through archaization and to exceeding the limits of the confessional paradigm.

The processes of globalization and Euro-Atlantic integration, the spread among the Russian youth of postmodern values ​​destroy the Orthodox tradition and its inherent culture and morality. In such circumstances, the study of the spiritual security of the individual becomes an issue, which the article aims at discussing. The authors come to the conclusion that in the process of forming traditional values ​​among young people, spiritual security is the semantic core of national security and a buffer of all negative trends related to the spiritual sphere. The spiritual security of Russia can and should be the guardian of the cultural and civilizational development of society, give impetus to the vital spiritual interests and needs of the individual. The society and the state face the task of developing forms and methods of public control over the formation of spiritual values ​​that will correspond to Russia's national interests. The central core of such spiritual system should be relations, within which patriotism and an active civil position, but at the same time, favorable conditions for the positive creation of spirituality will be provided. At the same time, relying on public interests and established religious norms of behavior within traditional confessions, the most numerous denominations – Orthodox and Islam – should influence the formation of the system of public relations and the upbringing of the spiritual and moral ideals of youth. The conclusions are confirmed by the results of a sociological survey conducted by the Don state technical university entitled "The ratio of youth in the Rostov region to the Russian Orthodox Church and believers in the context of their support for traditional cultural values", in which more than 1,000 students aged 18 to 35 of all leading universities in the region took part.

It is considered the problem of finding the formula of the inter-ethnic communication intensity coefficient in the context of the Russian modern polynational society. It should be emphasized that this concept of the theory of inter-ethnic communication is still sufficiently relevant and it was represented for the first time to the scientific community in the 1980s, by the well-known authority of Soviet Science, Professor M.S. Dzhunusov. In the view of the philosophical-anthropological and interdisciplinary approaches, as well as the migration processes both within and outside the Republic, it is justified the relevance of the studied problem, that is the problem of finding the formula of the inter-ethnic communication intensity coefficient. The concept is not only relevant, but also original. Special attention is paid to the comprehensive and interdisciplinary analysis of the concept "the formula of the inter-ethnic communication intensity coefficient" in a particularly specific region of modern Russia, such as the Republic of Dagestan, where a great number of Russian nationalities and the Republic have been sufficiently interacting for centuries. Based on regional aspect and transformation, the problem aims at the prospects of creating an integrated (variative) theoretical concept, taking into account the nature, specific characteristics and prospects of its development at a time of radical breaking of "Soviet stereotypes", traditions, analysis and evaluation of the system of national and international values and the principles of the study. Therefore, definite aspects of this reserach are objectively debatable. It covers various aspects of the problem, such as international communication (philosophical-anthropological, socio-psychological, socio-cultural, social, inculturation, identification, social contacts and relations in the system of communication and social relations).

«Хъуэхъу» (verbatim: praise, boasting), khokh is good wish in verbal form, part of traditional life and culture of peoples. The place and time of the utterance of khokh define its direction, depth, complexity. On the other hand, khokh is the art of folk eloquence. They are pronounced for various reasons: the beginning of the labor of the peasant, the new moon, housewarming, the wedding, the first row of mown hay, the exit to the spring field, the end of sowing, etc. The ability to pronounce khokh for the peoples of the North and West Caucasus is an indicator of human culture. The slightest violations of drinking etiquette cause frequent or awkwardness, or a violent reaction. There is a lot of traditionalism here. It is shown that khokh is not just words to the place and time, but words-feelings, word-concepts, words-sacral, organizing and subordinating people. Based on the study, it was analyzed various forms of toasts: from the times of the Nart epicado to the present day. The culture of communication at the feast table is shown. It is emphasized that the Apsuara and Adyghea formed the style of thinking and behavior of the people of the Northern and Western Caucasus. The urgency of research of the given phenomenon for understanding and penetration into depths of national consciousness, historical memory and traditions of culture of the people is grounded.

The history of the cotemporary Turkish language development is considered, special attention is given to the question of Turkish alphabet formation. The instances of grammatical constructions are given for illustration of Turkish word-formation and word-inflection agglutinative peculiarities.  It is marked the mutual penetration of foreign borrowings into Turkish language, as well as Turkisms into other languages, including the Russian language. It is mentioned the documents of the XVIII-XIX centuries, stored in the State Archives of the Rostov Region, which reflect examples of centuries-old relations with the Turkish neighbor. The basic part of the article is dedicated to the language reforms, conducted by Ataturk after the Turkish republic formation. A brief excursion into the history of the Turkish Historical Council and the Turkish Language Society creation was given, directions of their work, structure and leaders were characterized. The reforms results are given as the conclusion of the article.

It is examined the chronology of events, accompanying the presence of Adyghe people on the Crimea territory. The article provides historical facts, proving and illustrating habitation and development of the Adyghes on Crimean land, formation of their state system, realization of domestic and external nation policy. Despite the confirmation of low study of the problem, the author enumerates contemporary works of foreign (in particular, I. Klingen “Basis of economy in the Sochi district (1897)) and national scientists, and basing on this point begins to present old events of XVII – XIX c. exposing not only trade and political, but also friendly relations. The biography of Russian tsar Ivan the Terrible connected his life with Circassians by marriage on their representative in the days of Kemirgoko Idarov rule appears the apotheosis of this relation. Considering the military operations, captures and attacks, produced by rulers on the described territories in the examined period, it is illustrated the required coil of state contacts and a thesis about the Adygeis presence in Crimea. Underlining mention of Inal in folklore Adygei texts and establishing an appeal to this image in works of S.Khan-Girey and Sh.Nogmov, it is traced the fate and asserts the influence on the ethnos. Analysing the study of Inalids imperious period by the modern historians – A.Ostashko “Circassians and Crimea”, A.Maksidov “Historical and genealogical connections of the Adygeis with the people of Black sea Region” and F.Ozova “Cherkes-Italian historical crossing and parallels”, the author of the article mainly accepts their arguments and explains the position that allows to line up a personal reasonable construction.

Human activity significantly affects the substances content in the atmosphere, their natural cycles and budget. The chemical composition of atmospherical condensation is one of the main characteristics of atmospheric air pollution level. But in addition they also serve as a significant source of various substances inflow in maritime and continental ecosystems, capable to change their ecological state. Mainly this fact determines the urgency of studying the chemical composition of atmospheric precipitation. It is presented a comparative content characteristic of basic biogenic elements (inorganic nitrogen and phosphorus) in the atmospherical condensation in the background and urbanized areas on the Black Sea coast (v. Katsiveli and Sevastopol) and in the Rostov-on-Don region in May-September 2016. The difference of concentrations in condensations of background and urbanized regions is considered, the reasons of this difference are analyzed. The possible influence of condensations on the geological substate is estimated. It is shown that ammoniacal and nitrate were the basic forms of nitrogen in the atmospherical condensations of all observation points.  In Rostov-on-Don, the content of ammonium was significantly higher than the content of nitrates, which can be explained by the entry of this element into the atmosphere from rice checks, located near the sampling site. The concentration of inorganic phosphorus in the atmospherical condensations of Rostov-on-Don exceeded the concentration in the Crimean coast region in 5 times, which may be connected with the influence of rice checks and a grain terminal near the sampling stations, as well as the introduction of phosphates into the atmosphere by winds blowing in the direction from the Salsky steppes.

Analysis results, obtained during the expeditionary researches along the Russian Black Sea coast in 2007-2008, showed that significant increase of the biogenic matters in the coastal zone in comparison with the sea zone is usually observed at the confluence of rivers, in cities and in the ports. The main critical zones of ecological risk in the Black Sea are formed in the places of river runoff influence. With the recreational load on beaches and coast the increase of biogenic matters in the sea waters of littoral zones occurs, the cases of unfavorable treatment on dissolved oxygen are observed, the contamination level tendency stabilization of sea inshore waters is preserved.
