The Analytics of Additional Professional Education for Teachers in Pre-Professional Classes in Moscow Schools

Purpose of research. Teacher professional development (TPD) is a key issue of education policies globally. The solution of the issue is relevant for teachers of pre-professional classes in Moscow, since it is pre-professional classes that are assigned the role of effective tools for fulfilling the task of developing the innovative economy of the city.The objective of this study was to analyze the data on professional development and professional retraining of teachers in pre-professional classes in Moscow schools and find answers to the following questions:– What is the percentage of teachers engaged in additional professional education?– What is the intensity and dynamics of mastering programmes of additional professional education by teachers?– Where do teachers receive additional professional education?– Do the number of teachers in a school, the school’s ranking, the overall experience of teachers and the length of time of teachers in a given organization influence the additional professional education of teachers?Materials and methods. The study encompassed 2,215 teachers of pre-professional classes of 30 Moscow schools. The research methods included collection of data from the schools’ websites, processing data for statistical analysis, data analysis, and comparative analysis of different school indexes according to the selected parameters. Results. 72.8% of teachers of pre-professional classes were involved in professional development programmes, 21.8% of teachers – professional retraining programmes during the period of their work at school. 24% of teachers are continuously engaged in professional development. Mostly engaged in TPD are teachers who work at schools top-rated by “The Ranking of schools’ contribution to the quality education of Moscow students”. In addition, teachers with professional experience of less than 5 years are very actively engaged in teacher professional development. The number of school staff and prevalence of teachers with long record of service do not influence the scale of TPD engagement at schools. Additional professional education is not limited by the form of ownership, territorial affiliation, or the number of educational organizations in the region, and affects the positive dynamics in the diversification of teacher education, which is an important element of modern educational policy, the advantage of which is to improve the accessibility of education. The data of this research state that teachers were engaged in professional development programmes at 622 various organizations, of which 50.3% are state, and 49.7% - private organizations. Teachers were trained in 67 regions of Russia and 6 countries (the UK, the Netherlands, the Republic of Moldova, Switzerland, Ukraine, Estonia). The list of regions of the Russian Federation with the largest number of organizations in which teachers have mastered programs of additional professional education includes Moscow, the Moscow region, Saint Petersburg, Novosibirsk region, Krasnodar region, the Republic of Tatarstan, Stavropol region and the Udmurt Republic.Conclusion. The data obtained can contribute to the adoption of management decisions on the formation of professional development programs for teachers. The prospect of the study is the analysis of data on the impact of additional professional education of teachers on the educational results of students.

The influence of the level of compartmentalization on the export potential of the region, in the context of the Novosibirsk and Tomsk regions

The formation of the level of zoosanitary protection of enterprises is reflected in the assignment of the status of regionalization for especially dangerous animal diseases throughout the country. The Federal Service for Veterinary and Phytosanitary Surveillance ensures the safety of the territory of the Russian Federation from the introduction and spread of animal diseases. Assigning the level of compartmentalization to an enterprise depends on compliance with the basic standards for the maintenance and breeding of pigs, as well as the processing of pig products. The assignment of the highest level of compartmentalization allows the company to sell products almost without restrictions, both within the subject of the Russian Federation and between subjects, as well as for export. The emergence of outbreaks of particularly dangerous diseases not only in Russia, but also around the world causes great social and economic damage. The World Organization for Animal Health is developing principles for ensuring the biological safety of the territory. Carrying out preventive, diagnostic and therapeutic measures at enterprises form an increase in the level of zoosanitary protection and ensuring the safety of the spread of the disease. The topic of the article is new and relevant today, since the level of compartmentalization of enterprises in the region confirms the zoosanitary status of the territory. The export of meat products from the territory of the region depends on a number of factors, including the assigned status of regionalization. Increasing the export potential of the region depends on the interaction of authorities and enterprises. The fulfillment of the conditions of the importing countries is the most important principle of export supplies. Many enterprises are deprived of the right to export only because of the formal approach of fulfilling the requirements that lead to the identification of violations during the preparation of export shipments and the certification of the enterprise for inclusion in the registers of compartmentalization.

Pre-Pandemic Cross-Reactive Immunity against SARS-CoV-2 among Siberian Populations.

In December 2019, a new coronavirus, SARS-CoV-2, was found to in Wuhan, China. Cases of infection were subsequently detected in other countries in a short period of time, resulting in the declaration of the COVID-19 pandemic by the World Health Organization (WHO) on 11 March 2020. Questions about the impact of herd immunity of pre-existing immune reactivity to SARS-CoV-2 on COVID-19 severity, associated with the immunity to seasonal manifestation, are still to be resolved and may be useful for understanding some processes that precede the emergence of a pandemic virus. Perhaps this will contribute to understanding some of the processes that precede the emergence of a pandemic virus. We assessed the specificity and virus-neutralizing capacity of antibodies reacting with the nucleocapsid and spike proteins of SARS-CoV-2 in a set of serum samples collected in October and November 2019, before the first COVID-19 cases were documented in this region. Blood serum samples from 799 residents of several regions of Siberia, Russia, (the Altai Territory, Irkutsk, Kemerovo and Novosibirsk regions, the Republic of Altai, Buryatia, and Khakassia) were analyzed. Sera of non-infected donors were collected within a study of seasonal influenza in the Russian Federation. The sample collection sites were located near the flyways and breeding grounds of wild waterfowl. The performance of enzyme-linked immunosorbent assay (ELISA) for the collected sera included the usage of recombinant SARS-CoV-2 protein antigens: full-length nucleocapsid protein (CoVN), receptor binding domain (RBD) of S-protein and infection fragment of the S protein (S5-6). There were 183 (22.9%) sera reactive to the S5-6, 270 (33.8%) sera corresponding to the full-length N protein and 128 (16.2%) sera simultaneously reactive to both these proteins. Only 5 out of 799 sera had IgG antibodies reactive to the RBD. None of the sera exhibited neutralizing activity against the nCoV/Victoria/1/2020 SARS-CoV-2 strain in Vero E6 cell culture. The data obtained in this study suggest that some of the population of the analyzed regions of Russia had cross-reactive humoral immunity against SARS-CoV-2 before the COVID-19 pandemic started. Moreover, among individuals from relatively isolated regions, there were significantly fewer reliably cross-reactive sera. The possible significance of these data and impact of cross-immunity to SARS-CoV-2 on the prevalence and mortality of COVID-19 needs further assessment.

Application of expert systems for identification of vegetation classes in South Siberia

Due to the increase in the volume of primary factual data geobotanists have faced the problem of processing huge selection of geobotanical material. With the development of information methods, specialists have more tools to optimize their activities, one of which are expert systems that can successfully solve the problem of classification. An expert system was developed in 2020 by European researchers to identify habitat types in the EUNIS system. The aim of our work is to create our own expert system, based on the functionality proposed by European specialists, which allows to determine whether geobotanical descriptions belong to vegetation classes of the floristic classification. Classification of about 10000 descriptions of high-mountainous vegetation of the Altai-Sayan mountain region, vegetation of Novosibirsk region and Altai region as well as steppe and psammophytic vegetation of Transbaikalia by the Braun-Blanquet method using the expert system has been performed. The script written by us has shown its efficiency, allowing us to determine correctly the syntaxonomic affiliation of about 90 % of the descriptions. About 10 % of the data are either classified incorrectly or are not assigned by the system to any of the higher units under consideration, which is due to the uncertainty of diagnostic species within poorly studied classes, as well as to the non-obviousness of assignment to one or another class of transitional communities. To demonstrate the work of the expert system, a number of classes were mapped, showing their geographic distribution and latitudinal-zonal confinement, as well as the relationship between plant community types and ecological factors.

Effectiveness of the use of biopreparations and fungicides in the cultivation of spring wheat in the forest-steppe of the Priobye

The data on the effectiveness of using chemical, fungal and bacterial fungicides to treat seeds and crops of spring soft wheat in order to limit harmfulness of major diseases are presented. The research was conducted in 2020–2022 on chernozem leached forest-steppe of the Novosibirsk region Priobye. Chemical seed protectant Scarlet and its mixture with Vitaplan were the most effective dressers in the fight against root rots. It has been demonstrated that although biopreparations are inferior in efficiency to chemical ones, they act for a longer period of time and protect the plant from the disease for a longer period of time. Seed dressing with chemical preparation reduced the development of leaf diseases by 53–58%, and with biopreparations – by 34–41%. Titul 390 was the most effective of the vegetation treatments – 60–98%. The efficiency of the biopreparations was 42–64% in the years of moderate disease development. In the years of strong development of septoriosis or powdery mildew, the efficiency of biopreparations did not exceed 22–30%. The biological preparations had a growth-stimulating effect on the plants: they increased the flag leaf area by 22–39%. The seed treatment showed an increasing trend in the number of spikelets, grains per ear and grain weight per ear. Application of the preparations during the vegetation period increased reliably the ear length by 16–28%, the number of spikelets – by 15–20, grains – by 24–31, grain weight per ear – by 33–51%. At seed dressing the greatest increase in the yield (0.15 t/ha) was provided by Scarlet, when using a mixture of biological and chemical preparations it amounted to 0.11 t/ha. When treated during the growing season, chemical fungicide increased the yield by 0.33 t/ha, while biopreparations increased the yield by 0.11–0.14 t/ha. Complex use of chemical preparations (Scarlet + Titul 390) provided the maximum yield increase – 0.62 t/ha, from the joint use of chemical and biological preparation the yield increased by 0.15–0.33 t/ha. The biological preparations increased this indicator by 0.13–0.23 t/ha. It has been concluded that it is possible to select combinations of chemical and biological preparations that can control phytosanitary situation and provide acceptable yield.

Influence of different protection systems on phytosanitary situation in plantings of colored potato varieties

The results of the studies on the influence of various protection systems on the phytosanitary situation in planting colored potato varieties in the conditions of the Novosibirsk region are presented. It has been established that the chemical protectant Celest Top more effectively reduces the development of rhizoctoniosis (black scab) in comparison with the biological preparation Bactofort. On average, this indicator when using the chemical system was significantly lower by 4.8 times in the germination phase, and 2.0 times lower in the period of budding-beginning of flowering of the culture. A significant influence of the optimization of mineral nutrition for the biological preparation Bactofort was established, in this case, against the background of mineral fertilizers, the development of rhizoctoniosis is 1.2 times lower. In the phase of budding – the beginning of flowering the disease development on the fertilized background with the use of chemical system of protection is marked significantly higher by 1.4 times in comparison with the background of natural fertility, with the biological system in this period this indicator has no differences. The number of the Colorado potato beetle when using the chemical system was significantly lower by 3.6 times in comparison with the biologized one. Optimization of mineral nutrition with the use of a chemical protection system significantly increased the number of the pest by 5.0 times in comparison with the background of natural fertility, while with a biological system this indicator does not have significant differences. The productivity of the culture is significantly higher when using a chemical protection system in comparison with a biologized one by 1.5 times. On a fertilized background, when using a chemical protection system, the productivity of potatoes is significantly higher by 1.2 times in comparison with the background of natural fertiity. At the same time, with a biologized system, this indicator does not have significant differences. Individual reaction of the varieties to the studied protective techniques has been noted. Among the four varieties studied, All Red should be singled out, in which the development of rhizoctoniosis on the stems on both protection systems at both levels of mineral nutrition was generally the smallest among all variety samples. The varieties All Red and Violet were the least populated by the Colorado potato beetle – an average of 0.50–0.55 ind./plant. The highest yield was obtained when growing the Rosemaria variety (average factor 22.3 t/ha). To control rhizoctoniosis and Colorado potato beetle on potatoes, it is possible to use biological protection systems, but taking into account the biological characteristics of the varieties.

Clinical features and complication rates in type 2 diabetes mellitus clusters on five variables: glycated hemoglobin, age at diagnosis, body mass index, HOMA-IR, HOMA-B

Diabetes mellitus (T2DM) is a serious medical and social problem. Now they are studying the possibility of a new stratification of diabetes. The possibility of cluster analysis for different durations of diabetes, in different cohorts to identify phenotypic clusters of T2DM and validation by reproducing clusters is relevant. Identify clusters of type 2 diabetes mellitus in patients with different disease duration based on five variables: HbA1c, age at diagnosis, BMI, HOMA-IR, HOMA-B and study the clinical features and complication rates in each cluster in the Novosibirsk region. Cluster analysis of K-means was performed in 2131 patients with T2DM, aged 44 to 70 years, with a duration of diabetes of 6.42±5.66 years, living in the Novosibirsk region based on 5 variables - HbA1c, age at -diagnosis, BMI, HOMA-IR, HOMA-B. All patients a complete clinical and laboratory examination. The insulin resistance index in the HOMA (HOMA-IR, u) and the β-cell function assessment index (HOMA-B) were calculated using the calculator -version 2.2.3 at www.dtu.ox.ac.uk. Cluster analysis revealed: Cluster 1 included 455 patients with preserved β-cell function (HOMA-B 82.97±23.28%), moderate insulin resistance (HOMA-IR 5.57±4.72) and higher diastolic BP; Cluster 2 in 1658 patients with reduced function of β-cells (HOMA-B 21.71±12.51%), the lowest indices of insulin resistance (HOMA-IR 3.50±2.48) and was characterized by a longer duration of diabetes, high fasting glycemia , HbA1c, higher eGFR and MAU, men compared with women had a 31% higher risk of developing diabetic neuropathy and 28% more diabetic nephropathy; Cluster 3 in 18 patients with high function of β-cells (HOMA-B 228.53±63.32%), severe insulin resistance (HOMA-IR 6.92±4.77), features were high incidence of men, shorter duration of diabetes, lower fasting glycemia and HbA1c, lower diastolic BP and eGFR, high incidence of early development of diabetic retinopathy after 4.00±3.6 years. Cluster analysis in patients with different durations of diabetes mellitus confirmed the possibility of using cluster analysis to identify T2DM phenotypes in the Russian population. The clusters differed in the clinical characteristics of patients, the frequency and risk of diabetic complications. These results have potential value for early stratification of therapy.

RELIGIOUS IDENTITY, RELIGIOUS PRACTICES AND SPIRITUALITY OF THE POPULATION OF RUSSIA’S ASIAN BORDERLANDS

The religious identity of Russian citizens in modern conditions is transformed under the influence of socio-cultural processes of a global nature, often taking individualized forms and combined with practices of reviving interest in religion and its protective, compensatory functions in conditions of uncertainty. In 2022-2023, with the support of the Russian Science Foundation, a sociological study was conducted to examine religious identity, religious practices and spiritual security in the border regions (Altai Territory, Altai Republic, Tyva Republic and Novosibirsk Region, 1868 people). The population of the border regions gravitates towards Orthodoxy (36%), however, significant differentiations in the regional refraction of the religious mosaic. Orthodoxy prevails in the Altai Territory and the Novosibirsk Region, shamanism prevails in Tyva (52%), Burkhanism is represented in the Altai Republic (16%). Moreover, an index of religiosity based on the Huber methodology was calculated in the study. The index is built on the integration of the five structural components of religiosity: intellectual, ideological, public and personal religious practices, and religious experience. The average index of religiosity was 2.41 points, the most religious is the population of the Tuva Republic (2.75), followed by the Altai Republic (2.52), index values below the test norm (2.45) were recorded in the Altai Territory (2.36) and the Novosibirsk Region (2.16). Ideas about religiosity and spirituality are changing and acquiring new meanings in the light of changing social relations between believers and non-believers, emerging new practices and religious organizations.

A method for obtaining aqueous and dry ethanol extracts of grass (a mixture of flowers with leaves) and a stalk of St. John's wort (Hypericum perforatum L.) with inhibitory activity on the replication of the SARS‐CoV‐2 coronavirus in vitro

Aim. In vitro evaluation of the inhibitory activity of aqueous extracts and dry ethanol extracts of St John's wort (Hypericum perforatum L.) on the replication of SARS-CoV-2 according to three experimental schemes – direct inactivation (neutralisation) of the virus as well as "prevention" and "treatment" of cells.Materials and Methods. The laboratory strain SARS-CoV-2/human/RUS/Nsk-FRCFTM-1/2020 was passed on Vero cell culture. Water extracts and dry ethanol extracts of parts of H. perforatum L. collected during the flowering period in the Novosibirsk region were prepared. Dry extracts were dissolved in DMSO. Comparison samples are dry ethanol extracts of chaga, cloves and black tea.Results. It is shown that the aqueous extract of grass (a mixture of flowers with leaves) of H. perforatum L. with direct inactivation of the virus it is active in dilution of 1/4096. For the dry ethanol extract of the herb H. perforatum L., 50 % effective concentrations (EC50) were found equal to 2.44±0.87; 8.79±1.91 and 14.65±1.91 μg/ml respectively with direct inactivation as well as according to the "preventive" scheme and with the "treatment" of cells. Taking into account cytotoxicity, as well as in comparison with control samples, the values of selective indices (SI50) of the studied herbal preparations during direct inactivation were higher than with other experimental schemes and were distributed as follows (in descending order): 204.92; 153.68; 115.27; 32.01 and 21.33 for dry ethanol extracts of black tea from India, cloves, herbs, a mixture of flowers with leaves, of H. perforatum, chaga and the stems of H. perforatum respectively. The HPLC method has shown that the ethanol extract of the herb H. perforatum L. contains a greater amount of flavonoids than the extract of stems. Nevertheless, antiviral activity was also detected for the extract of stems of this plant with EC50 equal to 14.65±1.91; 78.13±20.05 and 117.19±15.31 μg/ml (according to three experimental schemes), respectively.Conclusion. For the preparation of antiviral drugs the whole plant of H. perforatum L., including stems, can be used as raw materials.

«Причиной развития хулиганства в деревне я считаю упадок религиозности в народе…»: рапорт священника Василия Ягунова благочинному 33-го благочиннического округа Томской и Алтайской епархии (1913 г.)

In this work, a source study of the report of priest Vasily Yagunov to the dean of the 33rd deanery district of the Tomsk diocese, written in 1913, was carried out. It is permanently stored in the State Archive of the Novosibirsk Region, in the collection of the Siberian Commission of Eastpart. This source is interesting, first of all, because it reflects the contradictory social processes that took place in the distant Siberian province in the chronological period preceding the First World War, the Revolution of 1917 and the Civil War. The increase in the number of archeographic works on the history of the Russian Orthodox Church determines the relevance of the chosen research format. This allows not only to introduce new sources into circulation, but also to make them useful for research on related scientific aspects. Through the analysis of the text of the report, the problem of the decline in the religiosity of the Siberian peasantry, which took place in the early 1910s, was studied. The published source allows you to identify the causes that caused the described phenomenon. In the introductory part of the work, the connection between the issue presented in the publication and the general historiography of the problem under study is given. The theoretical basis of the study was the anthropological approach, the principle of consistency, biographical and historical-genetic methods. This methodological totality made it possible, after an overview characterizing the personality of the author of the document (priest Vasily Yagunov), to analyze the process of moral and religious deviations, which was gaining momentum in the Siberian peasantry, using the example of everyday hooliganism of young people in churches. The published historical source may be of interest to a wide range of readers who study the history of the Russian Orthodox Church, social history, provincial everyday life and Siberian local history.

The content of fatty acids in blood plasma in men with arterial hypertension (“ESSE-RF3” in the Novosibirsk region)

Objective. The aim of the study was to investigate the content of fatty acids (FA) in the blood plasma of Novosibirsk men (“ESSE-RF3” in the Novosibirsk region) with established and newly diagnosed arterial hypertension (HTN). Design and methods. Within the framework of the multicenter single-stage epidemiological study ESSE-RF3 in the Novosibirsk region, 1200 residents of Novosibirsk (men — 600, women — 600) aged 35–74 years were examined. The random number study included 340 men with an average age of 54,63 ± 11,34 years, of which 156 people with established HTN, 49 had AH for the first time, and 135 people without HTN. In the blood plasma, the fatty acid spectrum of blood, including omega‑3,-6,-9 FA, was determined by highperformance liquid chromatography. Results. The level of alpha-linolenic and gamma-linolenic FAs was 1,21 (p = 0,005) and 1,39 times higher (p = 0,013) in the group of men with established HTN (who did not reach the target values of blood pressure against the background of therapy), respectively. The content of gammalinolenic acid was 1,46 times higher in the group of men with the first ever detected HTN (p = 0,038) when compared with the group of men without HTN. The relative chance of HTN in men, regardless of risk factors, is directly associated with an increase in the level of gamma-linolenic FA, and inversely associated with the level of hexadecenoic FA in blood plasma. Conclusions. Thus, from the studied FA in blood plasma, an increase in the level of gamma-linolenic FA can serve as an additional informative biomarker indicating a high probability of developing HTN in men.

Биологически активные вещества в цветках и листьях сортов сибирских ирисов

Abstract. In the last decade, garden varieties of Siberian iris (Iris sibirica L.) of the iris family (Iridaceae Juss.), which are valuable not only as ornamental plants, but also as a source of biologically active substances used in medicine and the perfume industry, have been very popular. Information on the presence of these substances in the generative and vegetative organs of the varieties of Siberian iris studied by us was not noted, which is the novelty and relevance of this work. The purpose of the study is a comparative study and assessment of the quantitative content of biologically active substances in the flowers and leaves of I sibirica and seven varieties from the Siberian irises (SIB) group cultivated in the forest-steppe zone of Western Siberia. Methods. The content of flavonols, catechins, carotenoids was determined by the spectrophotometric method, pectin substances by the carbazole-free spectrophotometric method and tannins by the titrimetric method. Results. The results of a comparative analysis of secondary metabolites in the aerial organs of irises showed that the content of tannins (1.3–3.2 times), flavonoids (1.5–4.6 times), catechins (5.0–6.3 times), carotenoids (2.6–9.5 times) higher in leaves than in flowers. The content of pectins is higher (3.5–9.5 times) and protopectins (1.2–1.9 times) in flowers. The varieties Fialcovy, Vals Katuni, Kassandra were distinguished by the highest indications for individual components. Variety and species specificity in the distribution of these components in the flowers and leaves of plants, as well as the influence of hydrometrological factors during the growing seasons of growth and development of 2020–2021, were noted. Scientific novelty. For the first time in the conditions of the forest-steppe zone of the Novosibirsk region, a comparative quantitative analysis of the content of tannins, flavonols, pectins, protopectins, catechins, carotenoids in the aboveground organs of Iris sibirica and its varieties: Baltik Blue, Blue Cup, Cambridge, Fialcovy, Kassandra, Mandy Morse, Vals Katuni was carried out.

A set of indicators of milk production in the Siberian Federal District is considered. Data are given for the leading regions of the district (Altai Territory, Novosibirsk Region, Omsk Region, Krasnoyarsk Territory), as well as Irkutsk Region. A comparative analysis of the development of dairy farming in certain regions of the Siberian Federal District showed that dairy farming in Siberia is one of the most important elements in the structure of the agro-industrial complex and makes a significant contribution to the development of Russian agriculture. Despite the reduction in the number of cows, there is an increase in the productivity of the dairy herd.

EFFECTIVENESS OF PRECISION AGRICULTURE ELEMENTS IN POTATO PRODUCTION IN THE WESTERN SIBERIAN FOREST-STEPPE

Theresultsofcomprehensiveresearchconductedin 2020-2022 usinggeoinformationtechnologies in potato cultivation at ZAO Plemzavod "Irmens" in the Ordynsky District of the Novosibirsk Region, located in the forest-steppe zone of Western Siberia, are presented. Potatoes require specific environmental factors to achieve high yields with good product quality. Using satellite navigation systems ensures an increase in potato yield and product quality. The research aims to develop elements of potato cultivation technology using innovative satellite navigation systems. The experiments were conducted in the soil and climate zone of drained forest-steppe in the northern forest-steppe area of the Priobye foothills. The soil of the experimental plots is alkaline black soil with a humus content of 6.32%, total nitrogen content of 0.28%, phosphorus content of 0.23%, and potassium content of 1.19%. The concentration of quickly hydrolysable nitrogen was 10.3, exchangeable phosphorus was 20.7, and exchangeable potassium was 14.4 mg/100 g of soil, with a pH of Early potato varieties Gala and Riviera were cultivated in the experiments. During the research period, aggregated data were obtained, and regression equations between yield indicators, the sum of productive soil moisture reserves, and precipitation in interphase periods of potato varieties were calculated. Correlation coefficients were determined for specific interphase periods. The dependence of potato yield on precipitation indicators in interphase periods was established. The significance of precision agriculture elements in ensuring early potato varieties' high product and quality was noted.
