Published: June 2021

Purpose. The article substantiates and confirms the thesis about the need for energy-oriented power consumption control levels in power complexes: the system of power supply at iron ore underground mining enterprises on the basis of experiment data analysis. Methodology. It is estimated that along with the current positive trend suitable for developing architecture of power consumption control levels when a limited number of energy-intensive enterprises consume about 80 % of the total power produced, their functioning modes in day hours vary. Analysis of varied realtime modes of power consumption in hours indicates absence of enterprises’ control over this process. Results. The suggested methods enable forecasting efficiency of power consumption control in hours in any variant of time-of-day tariff integration. In non-standard and changeable conditions of technological parameters in mining production, on the basis of the results of stochastic optimization analysis, it is proven that even when applying a small number of iterations N = 10, it is possible to improve the initial solution by over 60 % (the initial value of the objective function is I* = 27.7 and the final value on the last iteration is I* = 10.7). There are determined required vectors to specify a connection of the time-of-day tariff of ore mining (Р*) and the corresponding power consumption (Е*) which corresponds to the suboptimal value of the objective function (I*). The obtained results can be applied to developing recommendations for a more efficient planning of an enterprise’s performance. Practical value. The suggested algorithm implemented in power consumption control systems enables receiving a final result with any quality required for the level. If the quality of the obtained results needs improving, the number of iterations is to be increased by two or three orders of magnitude.

Authors: Niever Manuel , Trinh Han Jennifer , Kerres Roman , Hahn Carsten
Published: June 2021

In times of a complex, uncertain and dynamic world with increasingly faster product life cycles agile approaches in the early phase of product development are demanded in small and medium sized enterprises (SME’s). Despite the high demand, there is still no generally valid and need-specific solution concept for the integration of agile approaches due to different company specific requirements such as the level of maturity, experience and application purposes. Within this research, the question about the actual needs as well as the corresponding design of a concept for integrating agile approaches in product development for SME requirements is tackled. In order to identify existing challenges in the field of agile product development an empirical study with eleven mechanical engineering companies is conducted and analyzed. By using agglomerative-hierarchical clustering, three distinct types of SME’s with similar needs are structured. As a result, this research proposes a systematic procedure, enabling SME’s to be clustered by their needs and enable the integration of agile approaches through a problem-oriented roadmap with specified recommendation of actions. Enhancing the integration and application of agile approaches effectively in product development projects, the level of agility appropriate to the situation and needs must be identified and introduced. Therefore, the potential that arises from the process-oriented support of the product development teams in the early phase of innovation projects will be outlined. Keywords: agile approaches, needs analysis, small and medium sized enterprises, clustering, product development, mechanical engineering
Open Innovation: A New Source of Business Competitiveness
Authors: Oubaziz Saïd , Matmar Dalila
Published: June 2021

The appearance and diffusion of new forms of innovation called open, lead us to question the relevance of this new paradigm, access to a reformulation of the traditional vision, dedicated to internal control of the R&D process, towards a broadening of practices, including external opportunities in terms of ideas, technologies and skills required. It is clear that the efforts of companies in the field of innovation must enable them to reach a significant level of control, which will allow them to obtain a strategic positioning in terms of competitiveness. However, the major transformations of the last 30 years, in the technological, social and economic fields, have had significant effects and a very strong impact on the level of competitiveness of companies. It is undeniable that innovation is not only the sign of the vitality of a company, according to (Schumpeter), but also, a base on which will be the sustainable economic development of a society. Several experiences in the world, show the development of innovative strategies in the field of innovation, in its different forms, which consist in implementing a policy of strengthening individual and collective initiatives, by implementing new models of support to innovation, as the model of open innovation. Indeed, this form of innovation management tends to strengthen inter-company relationships and to increase the exchange of information and cooperation between the company and its partners. The objective of this work is to highlight the challenges of open innovation, by structuring networked companies around open innovation (BCG and CMI report 2008), and the opportunities offered by the latter to companies. This new vision which, according to (Chesbrouch 2003), no longer consists in being satisfied with the internal resources of the company, but rather in relying on the capacity for innovation of multiple external stakeholders.

Authors: Ковальов Леонід , Медведєва Марія , Побережець Іван
Published: June 2021

У статті викладено досвід використання інтерактивного імітатору фізичних процесів Step на заняттях з фізики у навчанні студентів спеціальностей «Агроінженерія», «Геодезія та землеустрій» та «Комп’ютерні науки».
Формулювання проблеми. Розуміння студентами дисциплін природничо-математичного циклу, зокрема фізики вважається основною проблемою у закладах вищої освіти. Візуалізація фізичних процесів допомагає зрозуміти, усвідомити та засвоїти більшість тем фізики. А завдяки імітаційному моделюванню студенти мають можливість побачити природу процесів і явищ, які не можна спостерігати не озброєним оком або без використання спеціальних потужних та дорогих приладів. Прикладом такого інтерактивного імітатору фізичних процесів може слугувати Step.
Матеріали і методи. Матеріалом дослідження є створення та дослідження студентами імітаційних моделей для вивчення поведінки пружного маятника, математичного маятника, явища резонансу, механічної хвилі та броунівського руху використовуючи інтерактивний імітатор фізичних процесів Step на заняттях з фізики. Методи спостереження, аналізу, систематизації та математичної статистики використовувалися для отримання інформації про доцільність використання інтерактивного імітатору фізичних процесів Step при навчанні фізики.
Результати. В статті описано методику використання інтерактивного імітатору фізичних процесів Step при навчанні фізики, зокрема вивченні пружного маятника, математичного маятника, резонансу, механічної хвилі, броунівського руху; відображено результати педагогічного експерименту.
Висновки. Узагальнюючи результати дослідження можна стверджувати, що використання інтерактивного імітатору фізичних процесів Step при навчанні фізики дозволяє: візуалізувати навчальний матеріал; полегшити сприймання та розуміння складних фізичних явищ та процесів; формувати у студентів дослідницькі компетентності; підвищити мотивацію навчально-пізнавальної діяльності студентів. Але разом з тим, використання лише імітаційних моделей не підвищує якість фізичної підготовки студентів.

Authors: Кудін Анатолій , Кудіна Тамара , Кархут Володимир
Published: June 2021

Формулювання проблеми. Робота присвячена вирішенню проблеми підвищення дискримінативності тестів з фізики шляхом введення нових форм завдань у тесті та процедур проведення комп’ютерного тестування. Гіпотеза дослідження: підвищення ефективності контролю за самостійною роботою студентів при переході українських університетів на змішану форму навчання потребує удосконалення методів і засобів комп’ютерного тестування.
Матеріали і методи. Розробка нових форм завдань у тестах проводилась на основі сучасної теорії дистракторів. Оцінка ефективності завдань нового змісту і форми проводилась в рамках педагогічного експерименту протягом року системи в автоматичному режимі. Аналізувались результати оцінювання навчальних досягнень 91 студента спеціальності 122 «Інженерія програмного забезпечення».
Результати. Проведено аналіз поширених в Україні платформ для організації комп’ютерного тестування (Google Форми, Quizlet, Proprofs, Kahoot!, ClassMarker, MyTestX, Test_2W, Testing, Plickers, Easy Test Maker і MOODLE). Констатується, що оптимальним рішення при змішаному навчанні - є модуль для тестування у відкритій LMS MOODLE. Наведені приклади вирішення навчальних завдань при вивченні фізики (перевірка системи знань з фізики, формулювання законів, схеми протікання фізичного процесу, алгоритм розв’язку фізичних задач, доведення теорем) за допомоги нових форм тестів. Наведено психолого-педагогічне обґрунтування формулювання дистракторів та введення нових форм тестів. Показана доцільність використання при змішаній формі навчання в університеті двох видів організації комп’ютерного контролю, які мають відмінні процедури проведення: систематична оперативна офлайн-перевірка роботи студента над матеріалом, що виноситься для самостійної роботи, та епізодичний модульний онлайн-зріз знань.
Висновок: використання розроблених технологій комп’ютерного тестування дозволяють значно покращити навчальні досягнення студентів з фізики при змішаному навчанні в університеті.

Authors: Розуменко Анжела , Розуменко Анатолій
Published: June 2021

Формулювання проблеми. В статті розглянуто проблему зниження якості математичної підготовки студентів різних спеціальностей.
Матеріали і методи. У ході підготовки статті були використані такі методи дослідження: порівняльний аналіз теоретичних положень, розкритих у науковій та навчально-методичній літературі; спостереження за математичною підготовкою майбутніх фахівців різних напрямів; бесіди із студентами; узагальнення педагогічного досвіду з викладання математичних дисциплін, анкетування (239 респондентів) та статистичні методи обробки експериментальний даних (метод статистичних гіпотез).
Результати. На основі аналізу моніторингових досліджень різних рівнів зроблено висновок про те, що якість математичної підготовки майбутніх фахівців має тенденцію зниження незалежно від напряму підготовки. Наведено результати експериментального регіонального дослідження, що підтверджують цей висновок.
Обґрунтовано необхідність проведення моніторингу математичних знань як одного із інструментів забезпечення більш якісної математичної підготовки студентів.
Запропоновано методичні рекомендації щодо підвищення якості математичної підготовки студентів першого року навчання різних напрямів підготовки.
Висновки. Підтверджено, що система моніторингу має бути комплексною та проводитися на всіх рівнях управління освітою як запорука валідності, надійності, економічності, інтегрованості та практичності. Моніторинг навчальних досягнень студентів є інструментом, який дозволяє забезпечити якісну математичну підготовку майбутніх фахівців. Здійснення експериментального дослідження дало змогу виявити відсутність узгодженості результату ЗНО, шкільного середнього балу з математики та результатів іспиту з математики, що складали студенти першого року різних університетів. Для уникнення прогалин та корекції знань першокурсників доцільно організувати протягом першого семестру повторювальний курс шкільної математики, завдання якого є узагальнення і систематизація основних фактів арифметики, геометрії, алгебри та початків аналізу. Це дозволить покращити якість математичної підготовки студентів закладів вищої освіти.
Analysis of the performance of public policies in Brazil to cope with sexual violence against children and adolescents
Authors: de Araújo costa Andréa
Published: June 2021

This article presents an analysis of the confrontation of the State to act against sexual violence against
children and adolescents, with a common name to the terms children and adolescents, with the objective of
discussing public policies. Efforts are concentrated on the legal and regulatory aspects for sustainability
and implementation of public policy programs in the Brazilian state. Initially, consideration was given to
the definitions and concepts of public policies based on the main doctrines and researchers on the topic,
such as Wildasky (1979); Maria Paula Bucci (2006), guidelines for making political decisions are added
in the structuring and formulation of concrete actions, as indicated by Enrique Saraiva (2006). Then, it
dialogues with the list of the main public policies arising from the action of the Brazilian state, listing
the main ones: Statute of the Child and Adolescent (ECA) through Law No. 8,069 of July 13, 1990; the
creation of the National Council for the Rights of Children and Adolescents (CONANDA) in 2000, among
other programs in the following years, including the National Plan to Combat Child and Youth Violence
(PNEVSCA), the Integrated Actions Program and References for Confronting Child and Youth Violence
in the Brazilian Territory (PAIR) and the Sentinela Program, which constituted a set of social assistance
measures to assist children and adolescents who are victims of sexual exploitation. In addition, it discussed
the international conventions adopted by the United Nations (UN) for the rights of children and adolescents,
as well as considerations about the indicators of sexual violence against them. Finally, it was concluded
that the National Plan to Combat Violence against Children and Adolescents in the Brazilian case was
important as a policy outlined and implemented in its different phases as a cycle of public policies, and
that despite the progress, the current perspectives are outlined by the state as incipient and without the
necessary resources as required. In this sense, the state’s policy focuses precisely on responding to various
situations of violence in the context of social vulnerability.
Arteria subcallosa: identificación previa al tratamiento. A propósito de un caso y revisión de la literatura
Authors: Gallo-Guerrero Marla , Joya-Ruvalcaba Diego , Badallo-Rivas Gil
Published: June 2021

INTRODUCCIÓN
La arteria subcallosa es la arteria perforante más larga de la arteria comunicante anterior (AcoA). A pesar de su gran importancia y de estar presente en el 50-79% de los ejemplares, está poco descrito en la literatura. Es fundamental su identificación previa a procedimientos endovasculares o quirúrgicos, ya que la lesión de esta arteria producirá un infarto bilateral de la región subcallosa y provocará un grave deterioro cognitivo y alteración de la memoria anterógrada, conocido como “síndrome amnésico subcalloso”.Presentamos el caso de un paciente con una malformación arteriovenosa peri callosa con identificación de la arteria subcallosa previa al tratamiento como única aferente. A menudo es difícil identificar esta arteria en las imágenes y su visualización previa podría prevenir secuelas importantes en los pacientes. Concluimos que la arteria subcallosa es la arteria perforante más importante de la arteria comunicante, por lo que su identificación previa al tratamiento es fundamental.

Published: June 2021

Although in vivo exposure therapy is highly effective in the treatment of specific phobias, only a minority of patients seeks therapy. Exposure to virtual objects has been shown to be better tolerated, equally efficacious, but the technology has not been made widely accessible yet. We developed an augmented reality (AR) application (app) to reduce fear of spiders and performed a randomized controlled trial comparing the effects of our app (six 30-min sessions at home over a two-week period) with no intervention. Primary outcome was subjective fear, measured by a Subjective Units of Distress Scale (SUDS) in a Behavioural Approach Test (BAT) in a real-life spider situation at six weeks follow-up. Between Oct 7, 2019, and Dec 6, 2019, 66 individuals were enrolled and randomized. The intervention led to significantly lower subjective fear in the BAT compared to the control group (intervention group, baseline: 7·12 [SD 2·03] follow-up: 5·03 [SD 2·19] vs. control group, baseline: 7·06 [SD 2·34], follow-up 6·24 [SD 2.21]; adjusted group difference -1·24, 95% CI -2·17 to -0·31; Cohen’s d=0·57, p=0·01). The repeated use of the AR app reduces subjective fear in a real-life spider situation, providing a low-threshold and low-cost treatment for fear of spiders.
The Middle Paleolithic Ground Stones Tools of Nesher Ramla Unit V (Southern Levant): A multi-scale use-wear approach for assessing the assemblage functional variability

Published: June 2021

In the archaeological record, Ground Stone Tools (hereafter GST) represent an important tool group that provides invaluable data for exploring technological development and changes in resource exploitation over time. Despite its importance, Lower and Middle Paleolithic (MP) GST technology remains poorly known and understudied. The MP record of the Levant constitutes a compelling case study for exploring the nature and character of GST technology. Especially the site of Nesher Ramla (Israel, end of Marine Isotope Stage 6/beginning of 5) has provided one of the world’s largest GST assemblages from MP contexts. Aiming at evaluating the variability of tool types at the site from a technological and functional perspective, this study follows an analytical approach which integrates different scales of analysis. Our workflow seeks to generate and combine qualitative and quantitative data allowing: 1) the identification of damage areas, and 2) functional analysis, based on the location, distribution, and characterization of use-wear traces. This study shows a substantial level of diversification in resource exploitation (e.g., mineral, hard animal material and likely perishable components). Results show the presence of several tool types on which diagnostic use-wear can be associated with different activities. Importantly, our analysis indicates the presence of various hammerstone types showing distinct wear characteristics. The variability observed within the hammerstones likely reflects different functions, including in some cases the processing of distinct worked materials. Ultimately, this study contributes to our understanding of the significance of GST technology for the ecological dynamics of MP populations.

Facial width-to-height (fWHR) revisited
Authors: Windmann Sabine , Stier Patrick , Steinbrück Lisa
Published: June 2021

To investigate peoples' trait attribution biases, we asked participants to generate faces of "bad guys" and "good guys" using three methods: free drawings, photo-editing, and feature assembly. In referring to research linking facial width (relative to height, fWHR) with aggressive and dominant personality traits in males, we compared fWHR displayed in the generated portraits between the two character types . We found that participants modelled emotional expressions (in particular, expression of anger and fear/friendliness), but not fWHR per se, to portray character trait. When emotional expressions were statistically controlled for, no difference in fWHR between "bad guys" and "good guys" remained. We conclude that emotion overgeneralization is a strong confound in research on fWHR.

Published: June 2021

Introduction: Suicide is a significant public health concern with increasing prevalence. Novel interventions that reduce stigma and increase accessibility, such as mobile health (mHealth) interventions, are urgently needed. Methods: This retrospective cohort intent-to-treat study examined suicidal ideation (SI) trajectories using multilevel models during and up to 6-months after an evidence-based 12-week mHealth intervention (Meru Health Program [MHP]) as assessed by the ninth item of the Patient Health Questionnaire-9 (PHQ-9). Estimates of associated suicide attempts and deaths by suicide were calculated using published data linking PHQ-9-assessed SI to records of suicide attempts and deaths by suicide. Results: MHP participants reporting SI “not at all” significantly increased between baseline and end-of-treatment (78.02% to 91.00%). Effect sizes of SI changes between baseline and end-of-treatment, 3-month, and 6-month follow-ups were 0.33 (95%CI=0.27-0.38), 0.32 (95%CI=0.27-0.38), and 0.32 (95%CI=0.27-0.438), respectively. Results also indicated an estimated 30.49% reduction (95%CI=25.15%-35.13%) in suicide attempts and death by suicide across treatment.Conclusion: This real-world study indicates that participants of the MHP show significant reductions in SI and estimated suicide attempts and deaths by suicide across treatment that are maintained 6-months following treatment.
Measuring Intergenerational Income Mobility: A Synthesis of Approaches
Authors: Deutscher Nathan , Mazumder Bhashkar
Published: June 2021

The literature on intergenerational income mobility uses a diverse set of measures and there is limited knowledge about whether these measures provide similar information and yield similar conclusions. We provide a framework to highlight the key concepts and properties of the different estimators. We then show how these measures relate to one another empirically. Our main analysis uses income tax data from Australia to produce a comprehensive set of empirical estimates for each of 19 different mobility measures at both the national and regional level. We supplement this analysis with other data that uses either within or between country variation in mobility measures. A key finding is that there is a clear distinction between relative and absolute measures both conceptually and empirically. A region may be high with respect to absolute mobility but could be low with respect to relative mobility. However, within broad categories, the different mobility measures tend to be highly correlated. For rank-based estimators, we highlight the importance of how the choice of the distribution used for calculating ranks can play a critical role in determining its properties as well as affect empirical findings. These patterns of results are important for policy makers whose local economy might fare well according to some mobility indicators but not others.

Authors: Hassan Yusuf , Pandey Jatin
Published: June 2021

Over the last few decades, social networking sites (SNS) have evolved as an effective medium of communication for the world. They are instrumental in connecting people across time and space with just a click. However, the darker side of SNS has resulted in a deteriorated human connection between individuals in real life. The current study is an attempt to examine the compulsive usage of SNS in detail. It utilizes a sequential mixed method design to examine the negative outcome of compulsive SNS usage and the effect of mindfulness in overcoming them. Findings of the study suggest that compulsive usage mediates the relationship between mindfulness and exhaustion; further, this relationship is moderated by extroversion personality traits.

The article reveals the peculiarities of the use of modern information technologies in the process of physical education classes for student youth. Modern fitness programs and fitness bracelets were analyzed, which made it possible to investigate the impact of modern technologies on the popularity of physical education and physical activity among modern youth and there is an increase in motivation to exercise. Therefore, the introduction of modern information technologies in the education system, which provide further improvement of the educational process, preparation of the younger generation for life in the information space, becomes important. The introduction of infocommunication technologies in the educational process can not only increase the efficiency of the learning process, but also form a physical culture, which increases motivation to exercise, lead a healthy lifestyle, physical improvement, improve the level of physical activity.

They will allow you to capture data from various sensors, display indicators on a color display, store information in cloud storage. The result of such devices will be a bio-journal with data on the state of physical fitness of a particular student. The device measures body temperature, heart rate, blood pressure, oxygen content, monitors sleep phases and stress levels, and has a fairly wide range of functionality: speedometer, altimeter, pedometer, calorie counter.

Therefore, there is a question in the development and implementation of a system of control and evaluation of physical activity, which would meet the modern requirements of the educational process and have an effective impact on improving the status of physical education and attracting young people to exercise.

The article reveals the influence of independent physical exercises on the improvement of physical condition. It is established that the level of health of modern youth is at a low level, which is due to the lack of motivation for physical education. It was found that most students are to some extent dissatisfied with the system of organization of physical education in higher education institutions. The article suggests ways to increase the prestige of physical education classes and improve motivation for independent exercise. First of all, it should be noted that independent exercise can not take place without awareness of the need for a healthy body and good health. The student's awareness of the need for exercise is the first step towards his personal development, regardless of where and how he wants to realize himself in this case. Physical education acts as an integral part of the general and professional culture of the student, as the most important qualitative dynamic characteristic of his personal development, as a fundamental activity that determines the beginning of his socio-cultural existence, method and extent of essential strengths and abilities. First of all, the student must be interested in the lessons, and also keep in mind that the body, spirit and mind - this is the only whole that is the essence of a healthy and harmonious personality. The student should also understand that his own body in many ways resembles a vessel, and it depends on the subject what and how to fill it. When exerting a pedagogical influence on a student, it is important to convey to him an understanding of this simple truth, and in physical education classes it is necessary to try to give maximum freedom to everyone. Of course, it is difficult to make a student aware of the need for physical education, and even more so through pedagogical skills to encourage him to do physical exercises, because in the educational program of higher education there are other subjects that require some time.

The article examines the influence of special physical training classes on the formation of physical readiness of cadets for future professional activities in the process of training at technical higher military educational institution. Cadets of the 1st-3rd years of study (n = 43) of the S. P. Koroliov Zhytomyr Military Institute took part in the study. Two groups were formed: experimental (EG, n=21), the cadets of which were engaged in the "CrossFit" classes, and control (CG, n = 22), the cadets of which were engaged according to the current system of physical training. Research methods: theoretical analysis and generalization of literature sources, pedagogical observation, pedagogical testing, methods of mathematical statistics. One of the means of physical training that can help solve the outlined problem is the means of special physical training "CrossFit". The essence of the "CrossFit" is to perform simple and affordable physical exercises for the development of physical qualities and different muscle groups by high-intensity circuit training (without rest between exercises or with short breaks for rest). It was found that the level of development of physical qualities among cadets who were engaged in the "CrossFit" classes at the end of the study was significantly higher than among those who were engaged in the current system of physical training during sports-mass work. The most pronounced influence of "CrossFit" classes was revealed on the development of the functional capacities of EG cadets (3 km running) and their strength qualities (pulling up on the crossbar).

Today, there is an increasing interest of the world community in the movement of veteran athletes, including wrestlers who specialize in Sambo (sports). Given the above, the leading and important role is played by scientific and methodological support of key components of the professional activities of veteran athletes who specialize in Sambo. The choice of the optimal technical and tactical arsenal of wrestlers of the studied category, considering their individual and typological features, allows to achieve the main goal – maintaining optimal sports form and winning competitions of various ranks in the selected Martial Arts. As a result of theoretical research, members of the research group developed a Program to improve the Technical and Tactical training of veteran Sambo wrestlers in the System of their annual training cycle. We expect that the introduction into the System of long-term training of veteran Martial Arts who specialize in Sambo wrestling programs to improve their Technical and Tactical training will increase the activity and effectiveness of competitive actions, which will ensure their successful performance in competitions of various ranks. Prospects for further research in the chosen direction of scientific research include testing the Program to improve the Technical and Tactical training of veteran Sambo wrestlers in the System of their annual training cycle, taking into account their individual typological and physiological characteristics.

There is growing evidence that arrhythmias are a major complication of COVID-19 infection. Inflammation of the myocardium, cytokine storm, hypoxia, changes of electrolyte levels, coronary vasospasm, microcloths may be factors that contribute to the development of arrhythmias and changes of the ECG. The aim of the study was to determine the sex and age characteristics of the prevalence and structure of cardiac arrhythmias in patients with severe COVID infection. In the study were examined 133 patients with severe COVID-19 infection, who were in the intensive care unit of the city clinical hospital №1 in Vinnytsia at the period from April to December 2020 and as a result of treatment with improved health were discharged from the hospital. Statistical processing of the obtained data was performed using the statistical software package SPSS 12.0 for Windows using parametric and non-parametric methods of statistical analysis. It was found that the most common comorbid pathologies of the patients with severe COVID-19 were – arterial hypertension 90 (67.7%), coronary heart disease 91 (68.4%), chronic heart failure 65 (48.9%), obesity 47 (35.3%) and diabetes mellitus 32 (24.1%). It was found that the prevalence of cardiac arrhythmias in patients with severe COVID-19 was 86 (64.7%) patients. Among all arrhythmias, tachyarrhythmias predominated – 68 (51.1%), in the structure of which sinus tachycardia was the most common in 45 (33.8%) and atrial fibrillation (AF) – in 19 (14.3%) patients, respectively. In turn, sinus tachycardia was significantly more common among women. The prevalence of bradyarrhythmias was 60 (45.1%), in the structure of which were dominated sinus bradycardia 16 (12%) and blockade of the right branch of the His bundle 30 (22.6%). Among men, there was a tendency to the predominance of complete left bundle branch block. The prevalence of ischemic changes and/or repolarization disorders according to the ECG was 119 (89.5%), in the structure of which were dominated the presence of inversion of the T wave 91 (68.4%) and depression of the ST segment 54 (40.6%). The mean age of the patients with ischemic ECG changes was significantly higher compared to patients without signs of repolarization disorders. Among men, there was a predominance of pancreatic hypertrophy and a tendency to predominance of left ventricular hypertrophy.

The work considers the solution to the urgent problem of reloading grain into vehicles and reducing its damage. The possibility of throwing grain at a given range by creating an appropriate ballistic flight path by adjusting the speed of the electric drive of the belt when it is powered by a frequency converter is substantiated. The problem of reducing the focus of grain scattering by forming the flow of grain and controlling its movement not only when moving on the belt, but also after the separation of the flow and its movement in the air. Focusing of the lower layer is achieved by giving it an additional initial speed, which is provided by the air flow from the fan installed under the belt. For the frequency converter of the electric drive of the fan, in the form of a regression model, the control law which considers parameters of grain and necessary range of transportation is synthesized. Experiment planning theory was used to synthesize the control law.
