The history of the fight against cholera epidemics in the Krasnodar territory in 1892 and 1910 (based on archival data)

Epidemics of a wide variety of infectious diseases were constantly recorded in Russia. Asian cholera occupied a special place among epidemic diseases. In 1892, cholera was imported into the Russian Empire through the Black Sea ports, which reached the territory of the Kuban region by the summer of the same year. In 1892, about 300 thousand people died of cholera in Russia. They still did not know how to treat this terrible disease, did not know its mechanism of spread, as well as the peculiarities of its course. The article, prepared on the basis of an analysis of documentary data from the Archive Department of the administration of the municipal formation of the city of Novorossiysk and the archival Department of the Administration of the municipal formation of the Mostovsky district, examines the cholera epidemic that swept the territories of the Kuban region in 1892 and 1910. The authors characterize the main factors that contributed to the rapid spread of infection and assess the measures that were taken to combat the disease: the implementation of anti-cholera measures organized by the authorities was greatly hampered by the lack of education, prejudices and superstitions of the vast majority of the population; representatives of the nonresident population not only did not comply with basic standards of personal hygiene, but also expressed distrust, and sometimes and hostility towards doctors. Using archival data, the authors investigate the impact of infectious diseases on the demographic indicators of these settlements.

The regional aspect of Russian healthcare development (using the example of the Krasnodar territory)

The article examines the modern aspects of the development of Russian healthcare in the regional context with an analysis of the main implemented measures and sources of financing. The efficiency of the industry's functioning directly affects the life expectancy and health of citizens; therefore, the analysis of priorities and sources of their financing is an urgent area of research. Most of the projects and plans in healthcare are focused on the long term, so the main part of the subprograms does not change significantly, defining the strategy, but priorities may change in the short term, and accordingly funding will be adjusted in the context of the main sources. Taking into account the leading positions of the region, we can note its leadership in the development of the industry in question. The socio-economic situation in the country also has an impact, for example, most experts pay attention to the fact that prices for medicines and medical equipment have increased, and this creates additional difficulties during planning and forecasting. Some expenses are simply necessary and at the same time take away significant funding - paying for medical care to the insured unemployed population and providing subsidies to state budgetary healthcare institutions, reducing the possibilities of other areas. The main source of financing for most subprograms is the budget of the Krasnodar Territory, the federal budget participates to a much lesser extent. The article touches upon the factors influencing the implementation of the state program «Development of healthcare» in the region and, as a result, the main key indicators of quality of life. The conducted practical research made it possible to determine in detail the current trends in the development of the industry in the regional aspect (using the example of the Krasnodar Territory).

AbstractA new species, Hyalesthes (Homalesthes) sagittus sp. n., of the family Cixiidae (Cixiinae, Pentastirini) is described from the Krasnodar Territory. The new species belongs to the Hyalesthes productus species group known from the Western Mediterranean and the Middle East. Natural disjunctive Western Mediterranean – Caucasian distribution as well as unintentional introduction of Auchenorrhyncha taxa are discussed.

Comparative characteristics of the durum wheat newest samples based on a complex of agrobiological characteristics

In 2020–2022 at the Dagestan experimental station of the VIR branch 30 samples of durum wheat of different ecological and geographical origins (Russia, Austria, Mexico, Syria, Egypt) were studied under irrigation conditions under winter sowing. The k-66674 Odari, k-67482 Yarina (Krasnodar Territory) and k-32453 Derbentskaya Chernokolosaya (Republic of Dagestan) varieties were sown as standard samples. Over three years of study, a field and laboratory assessment were given for the following characteristics: length of the growing season, resistance to fungal diseases (powdery mildew, brown and yellow rust) and lodging, grain weight per unit area (1 m2), weight of 1000 grains, number of grains in one ear and the mass of grain from one ear. The varieties are recommended as sources of breeding valuable traits (earliness, productivity, large grain size) for further use in breeding and genetic programs for the creation of new adaptive varieties.

Studying the efficiency of Gaprin application in sterlet farming

In the course of the experiment, the influence of new feed additives created on the basis of Gaprin and representing biomass of inactivated cell culture of non-pathogenic methane-oxidizing yeasts or bacteria on sturgeon fish productivity indicators was studied. The research was carried out in the Krasnodar Territory on sterlet fingerlings. The experiment lasted for 60 days. According to the scheme of the experiment, the 1st (control) group of fish received complete feeds without additives, i.e. containing 100.0% fish meal. In group 2 feeding, 50.0% fishmeal was replaced with 50.0% Gaprin. Group 3 diet contained 25.0% fishmeal and 75.0% Gaprin. In the feed for group 4, fish meal and Gaprin were in the ratio of 75/25%. In Group 5, fish meal was completely replaced by Gaprin, in this case the amount of additive was 10.5 kg. Sterlet fingerlings from Group 6 received feed with 10.0% Gaprin. The initial live weight in all groups was similar at 30 g. However, the inclusion of Gaprin in the diet by reducing the amount of fish meal contributed to an increase in the final live weight of sterlets in the experimental groups by 4.4–19.4% compared to the control. The exceptions were groups 5 and 6, which received 100.0 and 90.0% Gaprin instead of fishmeal. Final live weight in these groups was lower by 2.3 and 0.9%, respectively. Feed costs per 1 kg of live weight gain in the groups with partial or complete replacement of fish meal were lower relative to the 1st group (from 7.0 to 17.9%,).Inclusion of Gaprin in complete feeds contributed to the increase in profit from 553.00 to 1785.00 rubles.

The Influence of the Soil Profile on the Formation of the Elemental Image of Grapes and Wine of the Cabernet Sauvignon Variety.

The features for assessing the authenticity of wines by region of origin are studied, based on the relationship between the mineral composition of the wine, the grapes, and the soil profile (0 to 160 cm) from the place of growth of Cabernet Sauvignon grapes. Soil, grape, and wine samples were taken from the territories of six vineyards in the Anapa district of Krasnodar Territory, Russia. Using the methods of ICP-OES, thermal, and X-ray phase analysis, the soils were differentiated into three groups, differing in mineralogical and mineral compositions. The soil samples of the first group contained up to 31% quartz, the second group up to 25% quartz and 19% mixed calcite, and the third group up to 32% calcite and 15% quartz. The formation of the elemental image of the grapes was studied, taking into account the total content and mobile forms of metals in the soil. The territorial proximity of the vineyards did not affect the extraction of elements from the soil into the grape berry, and the migration of metals for each territory was selective. According to the values of the biological absorption coefficient, the degree of transition of metals from the soil to a berry was estimated. For K, Ti, Zn, Rb, Cu, and Fe in all berries, the coefficient was higher than 1.00, which means that the berry extracts contained not only mobile-form, but also difficult-to-dissolve metal compounds. The migration of macro-components from the soil to the berry was low, and amounted to 6-7% for Ca, 0.8-3.0% for Na, and 25-70% for Mg of the concentration of their mobile forms. For all territories, the maximum correlation between metal concentrations in grapes and soil was observed for samples from a depth of 0-40 cm. The discriminant model based on concentrations of Rb, Al, K, Sr, Co, Na, Pb, Ca, and Ni showed the formation of clusters in the territories of vineyard cultivation. The developed model allow the problems of identifying wines by region to be solved with high accuracy, using their elemental image.

Winter stress resistance of apple tree under the conditions of Krasnodar Territory

Background. Physiological and biochemical research on winter stress resistance of apple-tree cultivars of different ecogeographic origin under global warming is important for identifying the most adaptable genotypes for use in breeding practice. Such resistance is associated with the content of carbohydrates and anthocyanins, and the activity of peroxidase.Materials and methods. Two winter apple-tree cultivars developed at the North Caucasian Federal Scientific Center of Horticulture, Viticulture, Wine making (NCFSCHVW) and 3 foreign winter cultivars were studied using conventional physiological and biochemical methods.Results and discussion. The apple-tree cultivars ‘Orfey’ and ‘Prikubanskoye’ bred at the NCFSCHVW, when compared with foreign cvs. ‘Enterprise’, ‘Florina’ and ‘Ligol’, demonstrated higher contents of total water (by 2.5 %), starch (by 9.5 mg/g) and water-soluble sugars (by 19.3 mg/g) in shoots during the winter period. In the process of wintering, the anthocyanin content increased 2.9–4.3 times in the domestic cultivars, and 2.4–2.8 times in foreign ones. No regularities were found between the level of total peroxidase activity and winter hardiness of the studied apple cultivars.Conclusion. Cvs. ‘Orfey’ and ‘Prikubanskoye’ showed increased adaptability to the winter conditions in the unstable climate of Southern Russia, and can be recommended for cultivation in Krasnodar Territory and use in breeding practice.

Meteorological conditions for growing promising grape cultivars in the Black Sea agroecological zone of viticulture

Background. The pattern and duration of the grape plant growing season depends both on biological characteristics of plants and the environmental conditions of their habitat. Studying meteorological conditions and their effect on the growing phases of grape cultivars of different origin is important to optimize the deployment of these cultivars.Materials and methods. Eight introduced and domestic grape cultivars served as the research material. Phenological observations were carried out according to M. A. Lazarevsky, ANOVA was performed according to B. A. Dospekhov, the dependence of the duration of growing phases on weather conditions was assessed using pairwise correlations, and Student’s t-test was applied to determine statistical significance. Meteorological data were taken from the agrometeorological bulletins for Krasnodar Territory. The studies were conducted in the period from 2018 to 2021 under the agroecological conditions of the Black Sea viticulture zone.Results. Specific features of the temperature regime for grape growing phases in the environments of the Black Sea viticulture zone were ascertained. Indicators of heat supply and duration of the growing season according to Lazarevsky were used to identify the studied cultivars as early (‘Podarok Dmitriya’, ‘Reliance’, ‘Brigantina’ and ‘Anapskiy Ranniy’), medium (‘Concord’ and ‘Venus’), mid-late (‘Prikubanskiy’), and late (‘Kyoho’) genotypes. The sum of active temperatures required for the growing season of early cultivars was 2522–2603°C, for medium ones 2755–2760°C, for mid-late ones 2835°C, and for late ones 2970°C. According to the international classification, ‘Podarok Dmitriya’, ‘Reliance’, ‘Brigantina’ and ‘Anapskiy Ranniy’ are early, ‘Concord’, ‘Venus’ and ‘Prikubanskiy’ are mid-early, and ‘Kyoho’ is medium-ripening. All cultivars had a close direct relationship between the duration of their growing phases and the sum of air temperatures above +10°C.

Использование индексов вегетации в почвенно-ландшафтом картографировании и агроэкологической оценке

In this work, the possibilities of using remote sensing data to clarify the contours of soil differences were evaluated. It was found that visualization of mean annual vegetation indices NDVI allows to specify actual information on the contours of productivity zones. The use of this approach allows clarifying the boundaries of soil differences and identifying the actual boundaries of lithogenic lands with different productivity. It was found that the average annual NDVI in the linear model is related to the content of physical clay, with R2=0.26, the highest NDVI values are observed on soils of medium-loamy and heavy loamy composition in conditions of excessive moisture in the foothills of the Krasnodar Territory with average annual precipitation of more than 850 mm.

The state and trends of land use development in Krasnoarmeysky district of the Krasnodar territory

The article analyzes the state and trends in the development of land use in the rice-growing zone of Kuban. The lands of Krasnoarmeysky district were chosen as the object of study, since it is the main rice growing area in Krasnodar region. It has been established that rice production makes significant influence to the nature, as it changes and transforms the environment, and especially land resources. An analysis of indicators characterizing the state of the lands in Krasnoarmeysky district was carried out, and a forecast for each of these indicators was calculated here as well. The results of this forecast until 2035 indicate a gradual decrease of agricultural lands (and arable lands) in the area, that can lead to reduction of the resource potential of agricultural production. The dynamics of indicators of the sown area, gross harvest and yield of rice in Krasnoarmeysky region are considered by the authors. It was found that rice production is growing steadily, however, an analysis of changes in the area under crops and the gross yield of rice indicates the insufficient efficiency of the existing technology for cultivating this crop, based on the intensive use of mineral fertilizers. Forecasting shows huge increase of used mineral fertilizers, accompanied by a reduction of organic substances in the soil and deterioration of the environmental situation. In order to ensure the environmental sustainability of Krasnoarmeysky district, the new ecosystem approach to land use in the rice-growing zone has been proposed, including a set of environmental and resource-saving measures. As a result of the proposed measures, the structure of land use, crop rotation patterns and production technology have to be changed, use environmentally friendly directions, and preserve and improve the conditions of land resources.

Introduction. The relevance of the study lies in the study of the chemical composition of the food culture of Scorzonera hispanica of the "Lechebnye" variety, identification of the most significant, from the point of view of therapeutic nutrition biologically active substances and prediction of further possible ways of using raw materials of this plant in the development of functional foods. Purpose of the study. To study the qualitative and quantitative composition of substances determining the nutritional value of Scorzonera hispanic variety Lechebnye cultivated in the Krasnodar region, as well as a detailed study of the amino acid composition of the root and herb, and their water-extractable complexes for subsequent use in the development of food products of functional purpose. Material and method. The object of the study was the roots and grass of the Scorzonera hispanica of the "Lechebnye" variety, harvested in 2021–2023 on the territory of the North Caucasus branch of FGBNU VILAR. Dry water-extractable complexes of Scorzonera herb and root were obtained according to a well-known technological scheme, including the stages of solid-phase extraction, concentration of the resulting extract, purification by filtration and drying of the extract. Physico-chemical indicators of the nutritional value of the root and herb of Scorzonera hispanica: qualitative and quantitative composition of nutrients (protein, fiber, fat, calcium and phosphorus), safety indicators (arsenic, cadmium, were determined using generally accepted methods for food raw materials. Capillary electrophoresis was used as an analytical method for studies of the composition and content of amino acids in the studied objects. Results. It was found that the above-ground and underground organs of cultivated food plant Scorzonera hispanica cultivar Lechyorny in the Krasnodar Territory are characterized by a high content of physicochemical indicators of nutrients such as crude protein, fiber, fat. Thus, the mass fraction of crude protein in the root – 11.41%, in the grass – 10.43%, fiber in the root – 6.6% and 30.0% in the grass, crude fat in the root – 3.28%, in the grass –3.39%. The data of studies of amino acid composition of grass, roots of Scorzonera hispanica and their water-extractable complexes show that grass and root contain 12 amino acids, 7 of which are essential (threonine, valine, methionine, isoleucine, leucine, phenylalanine, lysine). The studied complexes revealed the presence of a number of substituted amino acids - tyrosine, cysteine, serine, proline, alanine, glycine and essential amino acids - phenylalanine, threonine, methionine, lysine, and valine, histidine and arginine, histidine and arginine (essential). Conclusions. The research results obtained allow us to conclude that the herb and roots of Scorzonera hispanica of the "Lechebnye" variety are valuable as sources of essential nutrients, such as protein, fiber, fat, calcium, phosphorus and amino acids, which provides the opportunity to consider the creation of functional food products based on these plant materials.

Geno-Species Composition of Borrelia Circulating on the Black Sea Coast of the Krasnodar Territory

The aim of the study was to assess the current epidemiological situation on Ixodidae tick-borne borreliosis (ITBB) (2017–2022) on the Black Sea coast of the Krasnodar Territory, to study the species composition of Borrelia.Materials and methods. Ixodidae ticks, Ixodes ricinus, Haemaphysalis concinna, H. inermis, Rhipicephalus sanguineus, were examined for infection with tick-borne borreliosis pathogens, followed by DNA sequencing of isolates. Species identification of Borrelia was carried out based on analysis of the nucleotide sequence of the 16S rRNA gene fragment using BLAST algorithm. Additionally, the OspC genotype was determined for isolates of pathogenic genovariants through comparing the obtained sequences with reference ones in the MEGA 5 program. The data were processed applying the cartographic method using the QGIS 2.18 software.Results and discussion. Between 2017 and 2022, 101 cases were registered on the Black Sea coast of the Krasnodar Territory, which accounted for 1.6 % of all ITBB cases in the Krasnodar Territory. The number of complaints with tick bites in Sochi was up to 191.4 per 100 thousand population. During the study, the predominant Borrelia geno-species on the territory of the Black Sea coast of the Krasnodar Territory was determined using sequencing – Borrelia lusitaniae (78.1 %). The circulation of geno-species B. garinii (6.8 %), B. valasiana (5.7 %), B. afzelii (3.6 %), B. miyamotoi (2.6 %), B. tanukii, B. bissettii (1.6 % each) was also observed. For Borrelia pathogenic species, appurtenance to OspC geno-groups was ascertained: four isolates were assigned to invasive OspC geno-groups, of which three B. afzelii isolates were genogroup A8, one B. garinii isolate was G7. High rate of infection of ticks with Borrelia was recorded in the surveyed area (up to 94.5 %). Borrelia of pathogenic species account for only 10.4 % of the total number of isolates studied. Mostly, genovariants that rarely cause diseases in humans (B. lusitaniae, B. valasiana, B. bissettii) and non-pathogenic Borrelia (B. tanukii) were found, which indicates a low risk of infection with ITBB pathogens.

Features of Distribution and Spread of <I>Hyalomma marginatum</I> (Acari, Ixodidae) Ticks in the Crimean Hemorrhagic Fever Focus in the Territory of Russia

The review provides the summarized and updated information on the current distribution of the tick Hyalomma marginatum in the natural Crimean hemorrhagic fever (CHF) focus in Russia. The work is based on the analysis of numerous literature sources, as well as the evidence from the personal collecting of ticks during long-term field research. In addition, the collection of ticks of the Stavropol Research Anti-Plague Institute of the Rospotrebnadzor and the database of H. marginatum collections in various regions of southern Russia were used. When delineating the boundaries of the H. marginatum areal and the CHF focus, we also deployed maps of the epidemiological survey of the focus, weekly and annual final reports on the CHF incidence from the Rospotrebnadzor Administrations. H. marginatum inhabits all regions of the Southern Federal District and the North-Caucasian Federal District, as well as the Crimean Peninsula and the south of the Saratov Region. The northern border of the areal reaches the Lugansk People’s Republic, Rostov, Volgograd, and Saratov Regions. H. marginatum is widely disseminated in the territory of Kalmykia and the Astrakhan Region. In the North Caucasus, it inhabits the entire flatland up to the foothills of the Greater Caucasus. The tick is widely distributed in the Stavropol Territory, populating the entire region. In the mountainous part of the Krasnodar Territory, this species is absent, but common in the rest of the areas. Beyond that, it is found on the Black Sea coast. In Karachay-Cherkessia, Kabardino-Balkaria, North Ossetia and Ingushetia, the tick lives in the northern steppe regions of the republics, in some places it invades the foothills. In Chechnya and Dagestan, the species widely inhabits the steppes and semi-deserts of the Terek-Kuma Interfluve. Moreover, in Dagestan, H. marginatum lives across the plain and foothill territory of the republic and even reaches the highlands up to a height of more than 2000 m above sea level. In addition, it is widely disseminated on the Crimean peninsula, both the flatland and the mountainous part.

Authentication of selected white wines by geographical origin using ICP spectrometric and chemometric analysis

An important aspect of assessing the authenticity of wines is its geographical origin. The aim of the work is to authenticate by geographical origin according to the data of the ICP-spectrometric and chemometric analysis of elemental "images" of wines produced from white grape varieties Chardonnay, Riesling and Muscat grown in four regions of the Krasnodar Territory, Russia. The difference in the contents of Al, Ba, Ca and Rb in wines was found depending on the variety, and Al, Ba, Rb, Fe, Li, Sr – depending on the region of grape growth. Different models of the experimental data processing were used for attribution of the produced varieties of wine to the area of the grape's growth. The criterion for the quality of the constructed models was the accuracy of the attribution of a wine variety to the area of the grape's growth (%). Analysis of the elemental analysis data of 153 wine samples showed that in terms of attribution accuracy, automated neural networks (100 %) are preferred among machine learning methods, followed by support vector machines (98.69 %) and general discriminant analysis (94.77 %). The applied mathematical models enabled the revealing of the cluster structure of the analyzed wine varieties and their attribution to the area of a grape growth with high accuracy. Sr, Li and Fe concentrations in wines were found as the dominating predictors in the constructed models for definition of the geographical origin of wines. The combination of ICP-spectrometric analysis data with the capabilities of statistical modeling of machine learning methods focused on large-dimensional data made it possible to successfully solve small-dimensional problems of the definition of the geographical origin of wines by their elemental composition and variety.

«По волнам» дворянской памяти: «золотое» детство уходящего сословия

Историография российского дореволюционного детства пополнилась замечательной книгой краснодарского историка И. Ю. Мартиановой. В своем исследовании автор отталкивается от стереотипного представления о дворянском детстве, которое через призму времени представляется современному человеку как «золотое», идеальное. Каким оно казалось самим дворянам времен империи, она и пытается рассказать в данной книге, написанной на основе опубликованных и неопубликованных воспоминаний представителей ушедшего в историю привилегированного сословия. В работе затронуты малоизученные вопросы отношений в дворянском обществе к детям и детству, семейного быта и духовной культуры дворян, социального статуса дворянского ребенка в семье и в обществе, описаны агенты и институты первичной социализации, рассмотрена проблема внебрачных детей. The review analyzes a monograph by Krasnodar historian Irina Yu. Martianova, which reflects one of the important aspects of the historiography of Russian pre-revolutionary childhood. The reviewer notes that in her research the author starts from the stereotypical idea of a noble childhood, which, through the prism of time, appears to modern people as “golden” and ideal. What it seemed like to the nobles themselves during the times of the empire is what she tries to tell in this book, written on the basis of published and unpublished memoirs of representatives of the privileged class that has passed into history. The advantages and disadvantages of the undertaken analysis of the impressive array of historical sources used by the author, including mainly documents of personal origin: 69 published memoirs and 2 manuscripts of unpublished memoirs stored in the State Archives of the Krasnodar Territory, are reflected. The author of the book traces the evolution of the historical appearance and the change in the life world of noble childhood over two centuries. The reviewer emphasizes that Martianova is one of the first authors in Russian historiography to pose and explore the problem of the situation of marginalized children among the nobility using the example of illegitimate children and children rejected by society due to various circumstances – both minor outcasts born into noble families in legal marriage and minors who were victims of big politics. The problem of young nobles’ perception of their own future is also reflected on the pages of the monograph. The reviewer characterizes the features of the author’s approach to the study of a number of little-studied issues: attitudes towards children and childhood in noble society, family life and spiritual culture of nobles, the social status of a noble child in the family and in society. The reviewer notes that the author describes the agents and institutions of noble children’s primary socialization, reflects the features of their national self-identification process. The author of the book was able to prove the close relationship between the change in the situation of a child from the upper class and the gradual elimination of the feudal mentality. The reviewer concludes that studying the childhood of representatives of the privileged class allows us to better understand the characteristic features of the Russian noble corporation as a whole as one of the cultural and historical communities in the Russian Empire.

Detailed chemical analysis of soils and identification of priority pollutants on the territory of the state aviation airfield (Krymsk)

In connection with the intensification of military activities, environmental problems have worsened in large-scale territories. The primary task is to create lists of priority pollutants of environmental objects that are mandatory for control at landfills for various purposes, military bases, airfields. The paper presents the data of a detailed geochemical analysis of the soils of the state aviation airfield territory, on the basis of which priority contaminants were identified taking into account their gross content, hazard classes and the frequency of exceeding dangerous concentrations relative to the background. In the Krasnodar Territory (Krymsk), 32 samples from the territory of the state aviation airfield were analyzed over 4 years of research, and background concentrations of 22 metals, petroleum products, formaldehyde and nitrate nitrogen were also established. To determine the hazard classes of metals with unspecified maximum permissible concentrations, a correlation analysis was carried out comparing the hazard classes of substances and their clarks. Based on the results of the study, a list of pollutants recommended for control has been compiled including cesium, arsenic, scandium, niobium, lead (hazard class I); antimony, formaldehyde, nitrate nitrogen (II); petroleum products (III). The variability of the distribution of concentrations of pollutants on the airfield territory depends on the specifics of the operation of aircraft and special equipment for flight support. But at all sampling points (beginning – end, runway perimeter; taxiways; under the glide path), the main soil pollutant is arsenic, which concentrations exceed background concentrations by 16–36 times. The dangerously high content of petroleum products, formaldehyde, nitrate nitrogen, and scandium and caesium in some points in the airfield soils has been also found.

Radioecological situation in certain areas of the Southern Federal District

Radioecological monitoring of natural and urban areas is intended not only to assess the consequences of the operation of nuclear fuel energy enterprises, but also to ensure radiation safety of humans and the environment. This type of research allows not only to identify areas with increased background radiation, but also to reduce social tension in the population associated with radiophobia. This paper presents the results of long-term studies of the ambient dose equivalent rate (ADR) of gamma radiation within urban and rural settlements of the Southern Federal District using the example of the Krasnodar Territory. ADR measurements were carried out at a height of 100 cm from the earth's surface using dosimeters-radiometers SRP-88n, DRBP-03 and DKS-96s with a detection unit BDKS-96s using pedestrian gamma survey methods. The study regions represent different types of landscapes: steppe plain territories, the foothills of the North Caucasus and the Black Sea coast. It is shown that the arithmetic average ADR values in urban conditions are 0.11 μSv/h, and in rural settlements – 0.14 μSv/h. Similar results may be due to differences in soil and climatic conditions in different settlements. In general, differences in gamma radiation ADR may be due to a greater extent to measurement uncertainty (standard deviation), and also, to a lesser extent, to relief features and the content of radionuclides in the soils of a given region. The radiation situation in the Krasnodar Territory at the time of the study complies with the requirements of SanPiN 2.6.1.2612-10. The gamma radiation equivalent dose rate values are within the limits of natural background fluctuations characteristic of the Russian Federation.

Диспетчерское сопровождение оказания первой помощи очевидцами события при внегоспитальной остановке кровообращения у пострадавшего: реалии и перспективы

Summary. Purpose of the study. The purpose of this work is to analyze the practical experience of remote support of first aid in out-of-hospital circulatory arrest using the example of the State Budgetary Institution of Health “Emergency Station of the Gelendzhik Resort City” of the Ministry of Health of the Krasnodar Territory. Material and methods. The empirical basis of the scientific research was the analytical material on dispatching support for the provision of first aid in case of out-of-hospital circulatory arrest, contained in the works of Russian and foreign scientists. A study was made of the regulations governing the organization of first aid, including dispatching support for its provision. Research results and their analysis. The experience of the GBUZ “Emergency Station of the Resort City of Gelendzhik” of the Ministry of Health of the Krasnodar Territory showed that the effectiveness of cardiopulmonary resuscitation in cases of circulatory arrest before the arrival of an ambulance, when eyewitnesses provided first aid during dispatching support (the proportion of successful resuscitations – 8.6%), was similar to that in cases of circulatory arrest in the presence of emergency medical professionals (7.4%). In this regard, one of the options for increasing the frequency and quality of CPR by eyewitnesses of the incident may be to accompany the CPR by a telephone emergency dispatcher.

Development of social competence of specialists of helping professions to carry out comprehensive prevention of suicidal behavior of adolescents

Introduction. The relevance of the research problem is due to the increase in maladaptive forms of adolescents' response to various kinds of crisis situations. The importance of preventing teenage suicides has increased dramatically in the context of the socio-cultural crisis of recent decades. Despite the fact that various sciences are developing and putting into practice more and more new methods and technologies for suicide prevention, alarming trends do not disappear. A real problem of training specialists of helping professions to organize complex, specifically filled activities for diagnostic, preventive, advisory, correctional and developmental work with adolescents is being formed. The purpose of this article is to consider the possibilities of supporting the activities of specialists in helping professions to work with adolescents in the prevention of suicidal behavior. Materials and methods. The study involved 133 students and 20 teachers of general education organizations (schools of the Krasnodar Territory, Russian Federation). To carry out diagnostics on the research topic, we used theoretical and empirical methods (in particular, analysis of psychological and pedagogical literature on the research problem, testing, conversation, the method of expert assessments, the method of content analysis), as well as methods of mathematical statistics. In the course of the study, we examined the manifestations of individual characteristics of self-esteem in children, the perception of loneliness, value orientations, and features of the emotional-volitional sphere. Also, within the framework of the study, we determined the content characteristics of the construction of a comprehensive work of specialists of accompanying professions with adolescents of the "risk group". The results of the study. As a result of the diagnosis of students in grades 8-9 (133 people), a "risk group" of 14 people was identified. To confirm the criteria for inclusion of adolescents in the group of suicidal risk – anxiety, frustration, a set of diagnostic techniques was used. It was determined that 43 subjects had an average or low level of anxiety, 90 respondents (67.66%) showed an increased level of anxiety. 57.14% of respondents revealed low self-esteem, while adolescents with adequate self-esteem accounted for only 34.58%. Teenagers who were assigned to the "risk group" demonstrated a fairly high level of loneliness: 7 of 14. The results of the study allowed us to identify areas in the prevention of suicidal activity of adolescent schoolchildren, for which it is necessary to prepare specialists of accompanying professions working in an educational organization. Conclusion. Based on the data of the conducted research, it is possible to note the multifactorial etiology of suicidal manifestations, which implies the need for a comprehensive psychological and pedagogical impact on all components of this phenomenon. The age peculiarity of a teenager determines the features of his suicidal behavior, which determine the specificity and uniqueness of prevention. Preventive work on suicide prevention should be built as an integral system that includes all levels of prevention, as well as a set of measures aimed at preventing repeated attempts. At the same time, the preventive activity of suicidal behavior should integrate several areas, such as: work with family, teachers, and adolescents themselves.
