Comprehensive assessment of the influence of territorial environmental factors and conditions of vocational training on the adaptation of the body of students in the development of working specialties

Professional training of cadets of lyceums in the process of mastering working specialties is accompanied by the influence on the adolescents' organism of ecological and hygienic territorial environmental factors, as well as specific factors of the educational and production environment. The study aims to explore the influence of factors of the environment and educational-production environment of river transport lyceums on the adaptation of adolescents' bodies in the process of teaching working specialties. A survey of 400 cadets studying at the Saratov and Balakovo lyceums of river transport (200 boys each) at the age of 15-18 years was carried out. The hygienic assessment of the organization and conditions of vocational training of adolescents mastering working specialties was carried out in accordance with SanPiN 2.4.3.1186-03, assessment of the conditions and nature of cadets' work in accordance with R 2.2.2006-05 "Guidelines for the hygienic assessment of the factors of the working environment and the labor process. Criteria and classification of working conditions". The processes of adaptation of the body of young men were studied in terms of psychophysiological status on a computer complex KPFK-99 - "Psychomat". To assess the adaptation of the cardiovascular system to physical activity, the Rufier index and the Martinet-Kushelevsky test were used. Statistical processing of materials was carried out using the program "Statistica for Windows 10.0". It is shown that vocational training of students in the process of passing educational practice in the shops of a ship repair enterprise, as well as swimming practice is accompanied by the impact on cadets of unfavorable production factors: microclimatic, increased sound pressure and vibration levels, exceeding the permissible content of chemicals in the air of the working area. The nature of the factors of educational and production activity of cadets during the periods of technological, swimming practice leads to a decrease in the adaptation processes of the body of young men, which is manifested by changes in the indicators of the psychophysiological status and functional activity of the cardiovascular system during stress tests. Negative factors of atmospheric air pollution of the environment, regardless of the territorial affiliation of the settlement, contribute to an increase in the overall incidence of cadets with a predominance of respiratory diseases. Among students with a deficit or excess body weight, in the process of passing professional practice, the number of people with low indicators of the body's adaptive ability to workloads is increasing.

Educational Influencers on Instagram: Analysis of Educational Channels, Audiences, and Economic Performance

Influencers have positioned themselves as opinion leaders capable of influencing large social groups, extending their presence to areas such as education. Instagram is one of the most consolidated social networks focused on the image where citizens interested in educational areas can find information from specialized channels on this topic. The purpose of this study is to analyze, during the period of confinement by COVID-19, the use of Instagram by educational influencers to consolidate their channel in new audiences, influence through interaction with their followers and create their transmedia production. Using a mixed methodological approach, a descriptive analysis of a sample of 810,200 users and a content analysis of 13 profiles of educational influencers is applied. The results show educational influencers as true experts in the use of Instagram, managing visually pleasing and harmonious profiles for new audiences. These influencers reach a large number of users, mostly women between the ages of 25 and 45 with an interest in “motherhood” on the platform. Educational influencers use digital marketing codes in their social networks, with a communicative style adapted to this type of space that seeks to increase the interaction and participation of new audiences and, as a consequence, economic profitability. There is a high number of influencers whose objective is to share educational resources, using their accounts as showcases for their transmedia educational production and for the sale or promotion of their productions and creations.

Academic and Educational Production Of A Master’s Student In EPT Of IFAP Macapá, Amapá, Amazônia, Brazil

Scientific production within undergraduate and graduate courses has its importance for the construction of a new way of thinking of the student. The Professional Master’s Degree in Professional Education in National Network (ProfEPT) unites disciplinary content, pedagogical knowledge, and the final academic production and links them to real situations of educational practice, and the final work can be presented in various ways (articles, books, educational products). The academic production, both of the advisor and the guiding, in addition to the importance related to scientific dissemination, has weight in the evaluation of the program and also in its maintenance. The objective of this work is to quantitatively show the academic and educational production of a master’s student in Professional and Technological Education (EPT) from the Institute of Education, Science and Technology (IFAP) of Macapá, Amapá, Amazônia, Brazil. During the master’s degree, scientific production in various forms proved necessary during the training process.

In addition to the importance in the contribution of scientific creation and dissemination, the productions tend to positively impact the evaluation and maintenance of the PROFEPT-IFAP program, carried out by CAPES.

Effectiveness of modern insecticides in protection of apple planting from blood-red aphids

Goal. To investigate an efficacy of the insecticides Movento 100 SC (spirotetramate, 100 g/l), Sivanto Prime 200 SL (flupiradifuran, 200 g/l) and Transform WG (sulfoxaflor, 500 g/ kg) on a reduction of a number and a harmfulness of blood-red aphid (Eriosoma laniqerum Hausm.), their impact on yields in commercial apple orchards. Methods. A field method, in the commercial apple orchards under the conditions of educational production department of Uman National University of Horticulture of the Ministry of Education and Science of Ukraine . A type of apple trees was Golden Delicious. Planting scheme — 4.0 × 3.0 m. Year of planting — 1992. Crown shape — sparsely (improved) — tiered. Rootstock — MM-106. Phases of plant development at application timing — “after blooming, fruit size — up to 20 mm” (BBCH 72) and “development of fruit (fruits about 90% of the final size)” (BBCH 79). Soil — shallow, low — humus dusty — loamy podzolic leached black soils: humus content — 1.3—2.5%; pH 4.8—5.2; mobile compounds Р2О5 — 130—180 mg/ kg and К2О — 8.9—9.2 mg/ kg (by Chirikov method). The measures for care of the experimental site — loosening a soil in the stem strips during the growing period, an application of organic and mineral fertilizers, a pruning, a splaying of grass between the rows (row spacing),a protection from pests and diseases. The technical effectiveness of applications was determined in different rates against blood-red aphids and their impact on yields in commercial apple orchards. Calculations were made according to generally accepted methods in in horticulture, plant protection and entomology. Results. The use of insecticides Movento 100 SC (spirotetramate, 100 g/l), Sivanto Prime 200 SL (flupiradifuran, 200 g/l) and Transform WG (sulfoxaflor, 500 g/kg) against blood-red aphids provided a reduction of this species in the number of 92.8—97.2%. It allowed to obtain a high — grade apple product with a yield of 1.7—1.9 times higher comparing to control. The outcome of non-standard products did not exceed 4,9% compare to 24,9% in the control (water treatment). An application of these insecticides allowed to increase the effectiveness of main biometric indicators of trees, namely: the average length of annual shoots, shoot thickness, leaf surface area by 52.4—76.9%, 1.1—1.2 times and 47.9—138.5%, accordingly, which is important for settlement of potential fruit buds and future yields. Conclusions. The use of insecticides Movento 100 SC (spirotetramat, 100 g/l), Sivanto Prime 200 SL (flupiradifuran, 200 g/l) Transform WG (sulfoxaflor, 500 g/kg) can reduce effectively the harmfulness of blood-red aphids in apple orchards and control its number during the growing period. A limitation of a number of the current sucking species in apple orchard by using the studied applications provided a yield increase and a marketable quality of the obtained fruit products and the effectiveness of basic biometric indicators of trees, namely: the average length of annual shoots, shoot thickness, leaf surface area, which is important for the potential yields in commercial apple orchards in the next years.

Evaluating class and school effects on the joint student achievements in different subjects: a bivariate semiparametric model with random coefficients

This paper proposes an innovative statistical method to measure the impact of the class/school on student achievements in multiple subjects. We propose a semiparametric model for a bivariate response variable with random coefficients, that are assumed to follow a discrete distribution with an unknown number of support points, together with an Expectation-Maximization algorithm—called BSPEM algorithm—to estimate its parameters. In the case study, we apply the BSPEM algorithm to data about Italian middle schools, considering students nested within classes, and we identify subpopulations of classes, standing on their effects on student achievements in reading and mathematics. The proposed model is extremely informative in exploring the correlation between multiple class effects, which are typical of the educational production function. The estimated class effects on reading and mathematics student achievements are then explained in terms of various class and school level characteristics selected by means of a LASSO regression.

Relationships that determine the quantitative block of financing in the scientific-informational and educational-production environment

The efficiency of sowing and harvesting processes in agriculture is one of the most important components of the success of an agricultural firm. Natural and climatic conditions typical for the majority of Russian agricultural territories impose restrictions on the timing and the fundamental possibility of sowing and harvesting. Therefore, the low efficiency of sowing and harvesting processes leads to a corresponding decrease in the volume of crop production. A number of works [1-4] consider various approaches to increasing the efficiency of sowing and harvesting, however, a systematic approach to the management of agricultural company processes requires the identification of the most significant reasons for the decrease in the efficiency and addresses as a priority their elimination (or reduction in the strength of their influence). The paper analyzes the reasons for the inefficiencies of sowing and harvesting processes and provides recommendations for reducing the impact of these reasons.
