STATISTICAL STUDY OF SPATIAL AND TEMPORAL DEVELOPMENT OF AGRICULTURE AT THE MESO-LEVEL

Significant transformations in the Russian economy in 1990-2000 negatively affected the development of agriculture. The number of workers in the industry has declined, and the production of some types of products has dropped to catastrophic levels. In this regard, we consider it timely and necessary to conduct a statistical study of the state of the industry at the meso-level and the factors that influence it. The aim of the research is to study the development of agriculture at the meso-level in the historical aspect based on statistical methods for assessing the current and forecasting future states. The object of research is Orenburg region and its municipalities, which is due to a number of reasons: the region occupies a stable leading position in the agriculture of Volga Federal District; the industry’s contribution to GRP is about 8%; municipalities of the region are in unequal conditions that affect the development of agriculture in the region. The development of crop production in Orenburg region in 1991-2019 characterized by an increase in sunflower production and a lateral trend in gross grain harvest, while the production of silage, annual and perennial grasses significantly decreased. The lack of a forage base against the background of low early maturity led to a significant reduction in the number of cattle - this negatively affected milk production in the region. Meat production managed to keep from falling only due to the growth of poultry population. The construction of regression models based on panel data covering 35 municipalities (period 2000-2019 and 5 variables) showed that three factors influence the volume of agricultural production - the availability of acreage, investment in fixed assets and the number of cattle. The constructed statistically significant regression model with fixed effects indicates a stable structure of producers and the presence of hidden factors. This determines the direction of further research, which consists in identifying latent variables that have a significant impact on the development of the region’s industry

Biochemical assessment of the quality of berries of the genus fragaria in the Orenburg Region

The assessment of the biochemical composition of the berries of strawberry varieties is of undoubted interest for the creation of a new generation of high-vitamin varieties. This article presents the results of three-year studies of the biochemical composition and taste of introduced strawberry varieties. The research was conducted in 2018-2020 on the basis of the Orenburg branch of the Research Center of Horticulture in the Orenburg Region. The aim of the study was to select the best samples by biochemical composition for further use in horticulture and breeding. The evaluation of varieties by chemical composition was carried out in accordance with generally accepted methods. The zoned varieties Orletz and Zenga Zengana served as a control. According to biochemical parameters, the content of soluble solids ranged from 4.0 to 9.1 %, with an average content of 7.5 %; titrated acidity was from 0.57 to 1.07 %, with an average content of 0.88 %; the content of ascorbic acid (vitamin C) was from 31.6 to 62.7 mg%, with an average content of 48.4 mg%.The average tasting rating of the studied varieties was 4.4 points. The control varieties Orletz and Zenga Zengana had 4.0 and 4.2 points, respectively. As a result of the study varieties Kokinskaya Zarya, Pervoklassnitsa, Polka, Troubadour, Tsaritsa were revealed according to individual biochemical parameters and taste and can be used as a valuable source for further breeding work.

Creation of the Project of the digital educational platform “My Format” for the educational environment in the Orenburg Region

The purpose of the article is to substantiate the creation of the project of the digital educational platform “My format” on the territory of the Orenburg region. Currently, there is no such digital platform in the region, which leads to gaps in the interaction of participants in the educational process. The main idea of the project is to describe a digital platform created for students of schools, teachers, administration of educational institutions, parents of students, universities, colleges and NGOs in the Orenburg region. A digital educational platform should create an information space that will unite participants in the learning process. Each of the interested parties, thanks to the platform, can satisfy their needs. For example, students will have the opportunity of remote education, teachers will have access to methodological materials and information, school administration (representatives of employers, universities, etc.) the ability to carry out testing to control the level of knowledge of students. The authors of the article, in order to implement the proposed idea, created a model of the functioning of the “My Format” platform, identified the advantages and opportunities from its use by interested parties. During the work, possible risks (barriers) were identified, a roadmap (milestones) was prepared, and the main indicators for evaluating the effectiveness of the project were identified. At the end of the article, the relevant conclusions are made, summarizing the results of the study.

Organization of Medical Support for the Military Service Call-Up of Citizens during New Coronavirus Infection COVID-19 Pandemic

The aim of the study was to evaluate the organization of screening of conscripts for COVID-19 infection in one of the subjects of the Russian Federation — Orenburg region. Materials and methods of the study. The study of organization of examination of conscripts for COVID-19 infection included study of the experience of the Center of Military Medical Examination of the Military Commissariat of Orenburg Region in carrying out military conscription under conditions of the COVID-19 pandemic; methodological recommendations approved by the Head of the Main Military Medical Department of the Defense Ministry of Russia as well as the analysis of the activities carried out at different stages of medical sorting. Results of the study and their analysis. The results of the study of the organization of COVID-19 screening of conscripts in Orenburg Region showed that sufficient and effective barrier medical screening was organized at all stages. Conscripts in good health condition were sent to the Armed Forces for military service under conscription. No claims were received from military units about poor quality selection of conscripts. In 2020, during the COVID-19 pandemic, recruitment commissions of Orenburg Region coped successfully with the task of drafting citizens for military service.

Historical and medical aspects of the formation and development of regional general medical practice

The results of the historical and medical analysis of the processes of formation and development of primary care in the Orenburg Region are quite relevant, especially in connection with the renewed demand for resolving urgent issues that have arisen in the system of domestic health care. Consideration of the above aspects on the example of a separate territory, the Orenburg Region, is significant, given that public health care is formed by various structures of territorial systems in the context of demographic, social and economic gradations.

The composition of phytoplankton as an indicator of the ecological state of the middle course of the Ural River and its tributaries

The article presents the results of the analysis of the systematic structure of the algae flora of the studied reservoirs of the Orenburg region. The revealed richness of flora includes 104 species and varieties belonging to 7 divisions, 12 classes, 23 orders, 32 families, 58 genera. The dominant divisions are Chlorophyta, Bacillariophyta and Cyanophyta. The total number of microalgae at the study points was dependent on the anthropogenic load on the reservoir. Certain indices of saprobity of reservoirs indicate the presence of dissolved organic matter in the bulk of the studied reservoirs and pollution of natural waters. Keywords: NATURAL RESERVOIRS, WATER QUALITY, ALGOFLORA, URAL RIVER, SAPROBITY
