Published: April 2020

A Lei n.º 13.415/2017, sobre a Reforma do Ensino Médio, apresenta-se como uma ameaça ao projeto educativo do Ensino Médio Integrado (EMI). No presente artigo, com foco na análise do Projeto Pedagógico Institucional (PPI), busca-se compreender a materialidade das contradições, por meio do discurso textual, entre o proclamado e o realizado, tendo como referência a concepção histórico-crítica. Para isso, faz-se uso dos recursos da análise documental e pesquisa bibliográfica, com abordagem no materialismo histórico dialético. Por fim, a partir da análise dos projetos dos cursos técnicos de nível médio, na sua forma integrada, constata-se evidências preliminares do distanciamento entre a concepção educativa institucional e os projetos de curso do EMI, o que ajuda a compreender os limites de uma resistência da comunidade acadêmica frente a atual Reforma do Ensino Médio.

Authors: Bilar Jéssica De Góes , Hohemberger Rômulo , Coutinho Renato Xavier
Published: April 2020

A água é um tema constantemente abordado em sala de aula, devido a sua importância e interferência no meio ambiente, porém muitas vezes ele é tratado de maneira isolada e descontextualizada. Assim, o objetivo desta pesquisa é analisar a implantação de um projeto interdisciplinar tendo como tema a água, observando dificuldades e percepções de alunos e professores ao longo do processo. Este é denominado “Prática Profissional Integrada”, realizado no Instituto Federal Farroupilha, envolvendo o curso Técnico Integrado de Agropecuária. Este projeto é composto por três ações (conjunto de palestras de sensibilização para o tema e 2 dias de campo) as quais envolvem todos os estudantes do curso e professores das áreas técnicas e básicas. Através das ações desenvolvidas foi possível verificar um aumento do interesse dos alunos pelos conteúdos trabalhados e a integração entre as disciplinas e áreas de conhecimento, possibilitando uma preocupação e responsabilidade quanto ao consumo da água.
Dynamics and exact solutions of the generalized Harry Dym equation
Authors: Matviichuk Ruslan
Published: April 2020

The Harry Dym equation is the third-order evolutionary partial differential equation. It describes a system in which dispersion and nonlinearity are coupled together. It is a completely integrable nonlinear evolution equation that may be solved by means of the inverse scattering transform. It has an infinite number of conservation laws and does not have the Painleve property. The Harry Dym equation has strong links to the Korteweg – de Vries equation and it also has many properties of soliton solutions. A connection was established between this equation and the hierarchies of the Kadomtsev – Petviashvili equation. The Harry Dym equation has applications in acoustics: with its help, finite-gap densities of the acoustic operator are constructed. The paper considers a generalization of the Harry Dym equation, for the study of which the methods of the theory of finite-dimensional dynamics are applied. The theory of finite-dimensional dynamics is a natural development of the theory of dynamical systems. Dynamics make it possible to find families that depends on a finite number of parameters among all solutions of evolutionary differential equations. In our case, this approach allows us to obtain some classes of exact solutions of the generalized equation, and also indicates a method for numerically constructing solutions.
Classification of curves on de Sitter plane
Authors: Streltsova Irina
Published: April 2020

In 1917, de Sitter used the modified Einstein equation and proposed a model of the Universe without physical matter, but with a cosmological constant. De Sitter geometry, as well as Minkowski geometry, is maximally symmetrical. However, de Sitter geometry is better suited to describe gravitational fields. It is believed that the real Universe was described by the de Sitter model in the very early stages of expansion (inflationary model of the Universe).
This article is devoted to the problem of classification of regular curves on the de Sitter space. As a model of the de Sitter plane, the upper half-plane on which the metric is given is chosen. For this purpose, an algebra of differential invariants of curves with respect to the motions of the de Sitter plane is constructed. As it turned out, this algebra is generated by one second-order differential invariant (we call it by de Sitter curvature) and two invariant differentiations. Thus, when passing to the next jets, the dimension of the algebra of differential invariants increases by one. The concept of regular curves is introduced. Namely, a curve is called regular if the restriction of de Sitter curvature to it can be considered as parameterization of the curve. A theorem on the equivalence of regular curves with respect to the motions of the de Sitter plane is proved. The singular orbits of the group of proper motions are described.
The Russian Idea in the Historiosophy of Margarita Sabashnikova-Voloshina
Authors: Varga Patrik
Published: April 2020

This article aims to single out and interpret ideas connected with the role of Russia and the Russian people in world history and the development of humanity and space in the literary heritage of Margarita Sabashnikova-Voloshina, a Russian artist, poet, and representative of anthroposophy. This article examines her biography of St Serafim of Sarov and her autobiography The Green Snake, first released in German in 1954. Although Sabashnikova-Voloshina does not use the expression “Russian idea” in any works to denote her historiosophic ideas relating to the mission of Russia and Russians, the author argues that she has a complex of ideas about Russia’s mission. The article looks at texts of Rudolf Steiner that reflect his views on humanity’s development by means of a consecutive alternation of cultural epochs, pointing out the presence of such ideas in the works of Sabashnikova-Voloshina. According to the article, she continued to refer to them into the Soviet period when interpreting certain facts connected with Russian history and the Russian people. She considered the Soviet state a tragedy, a disaster, and a betrayal of the “Russian idea”.
Letters of Orthodox Priests about the German Occupation of Estonia during the First World War
Authors: Paert Irina , White James M.
Published: April 2020

During the invasion of the Baltic provinces between 1915 and 1918, a large swathe of territory and its population fell under German control: this included Orthodox parishes and their priests. The clergy and laity thus had to face many new challenges: the behaviour of occupation forces, material deprivations, and the actions of Lutheran clerical and secular elites in the new context. This article focuses on the response to the advance of the German armies in 1915 and 1916 into the Baltic. On the one hand, the article addresses the preparation and execution of the evacuation of the clergy and the rhetoric that underpinned the process of evacuation. On the other hand, it examines the problem of the church life under occupation. As evident from the sermons and articles published in the ecclesiastical press, the Germans represented a major threat to the Orthodox faith, clergy, and church property. Thus most Orthodox institutions were evacuated from the Baltic in 1915. Finally, the article discusses the position of the Orthodox Church during German occupation of the Estonian islands seized by the imperial German navy on 3 November 1917 from the perspective of parish priests. The article is based on the letters written by priests to the bishop of Riga and provides a complex picture of the German occupation, much of which differs from the representation of Germans in Russian war propaganda. Most priests represented the German forces as being relatively respectful towards churches and the clergy: their main complaint against the soldiers was the seizure of food, horses, and property, with the concomitant disruptions and discomforts this caused. The more serious threat to Orthodoxy, according to this evidence, came not from Germans but from the Lutheran clergy, who allegedly used the opportunity afforded by the invasion to undermine the Orthodox Church’s position. This publication will provide a unique insight into religion under occupation during the First World War, revealing the difficulties of maintaining everyday religious life in a multiconfessional region during and after invasion.
Bionic approach to the design of bridge structures. Part 1: Features of the bionic approach in relation to building structures
Authors: Ovchinnikov Ilya , Karahanyan Artur , Ovchinnikov Igor
Published: April 2020

General approaches to the application of bionic approach to the design of building structures, in particular bridge structures are considered. It is shown how the development of bionic design ideas influenced the development of bridge design and how the ideas of bionic design are improved, creating a new language for the future bridge design industry. It is noted that today in Russia the problem of bionic approach in the design of bridges, despite the appearance of a number of works is little studied. Briefly describes the history of the use of the bionic approach in architecture and construction. The possibility of applying the theory of inventive problem solving (TRIZ) when using a bionic approach to design is indicated. A number of examples of bridge structures designed using the bionic approach are given, their advantages and disadvantages are analyzed. Moreover, both stationary bridge structures and living bridges that change their configuration depending on the operating conditions are considered. In conclusion, it is pointed out that, although the topic under study is rather poorly studied in Russia, but this direction is very promising and therefore needs further development.

Research methods used in this article: review of scientific publications, logic, deduction, induction, comparative analysis of socio-economic changes, descriptive method.
As a result of the study of publications on the subject and own observations, it was concluded that through the study of social interactions, it is possible to expand the scientific tools for the study of economic development of economic entities.
It is proved that the socio-economic behavior of economic entities is formed due to the structure of preferences and dependence on the institutional environment.
The authors came to the conclusion that to study the socio-economic behavior of economic entities should carry out methodologically the study on the impact of social interactions on the behavior of individuals, systematic study of social interaction in different institutional environments and their relation to economic growth, to use a new approach to determine the relationship of economic psychology and social interactions.

Население России стареет, поэтому настоящие и будущие поколения 50+ численно растут. Старение можно рассматривать в дискурсе «рисков старения», но этот, придуманный Всемирным банком (World Bank ) термин, не только дискриминационный, но и не отражает того факта, что избыточная рождаемость и быстрый рост населения в ряде стран (в Центральной Африке, Индии, ЮАР, например) создают ситуации массового голода или, в более легком варианте – увеличения нагрузки на работающее население. Как нам кажется, пожилые могут и даже должны рассматриваться как значительный общественный и трудовой ресурс. Для этого потенциал пожилых необходимо сохранять и культивировать. Мы видим три основных механизма интеграции пожилых в современной ситуации: через систему занятости, семейные и социальные сети поддержки, государственную помощь. Основной путь активизации социального поведения – трудовая занятость, но в реальности занятость пожилых имеет прекарный характер и в России, и в Западной Европе, а в рамках сложившейся социальной политики этому не уделяется внимания. Но все же в последние годы занятость пожилых за пределами пенсионного возраста растет Однако для многих представителей старших поколений до сих пор характерны неэффективные инерционные социальные траектории в отсутствие привлекательных предложений по развитию (или механизмов вовлеченности, причастности). В числе прочего и новый Закон «О социальном обслуживании населения», скорее, сужает поле активизирующих услуг в целом, и социального обслуживания пожилых. Во взаимодействии государства с пожилыми заметно отсутствие ясных приоритетов. Статья продолжает наши исследования пожилых. ведущиеся в ИТМО по гранту РНФ с 2014 г.

Authors: Жигадло Валентин Эдуардович , Одинокая Мария Александровна , Пятницкий Алексей Николаевич
Published: April 2020

Данная статья рассматривает актуальные междисциплинарные вопросы гуманитарного знания, связанные с изучением и формированием языковой компетенции студентов, профессионально-ориентированному обучению иностранного языка и преподаванием профессиональных дисциплин с помощью иностранного языка. Статья раскрывает опыт создания интерактивного обучающего учебника по введению в программную дисциплину «Базы данных», описывается его структура, содержание и другие аспекты его разработки и практического использования. В статье представлен пример использования современной интерактивной технологии интегрированного предметно-языкового обучения CLIL с использованием образовательной платформы LMS MOODLE , а также раскрыты характеристики данной платформы, способствующие эффективному развитию профессиональных и лингвистических компетенций студентов. Особое внимание уделяется тому, что предметно-языковое обучение занимает в вузовской практике определенную нишу, формирующуюся отдельными преподавателями, одинаково владеющими как своей профессиональной дисциплиной, так и иностранным языком. В статье делается вывод о том, что в целом предметно-языковое интегрированное обучение является полезным и востребованным направлением, способствующим созданию условий для продуктивного освоения профессионально-значимой информации дисциплин различного цикла с помощью иностранного языка, созданию условий для самореализации и саморазвития человека.

Authors: Богдановская Ирина Марковна , Королева Наталья Николаевна , Привалов Артем Владимирович
Published: April 2020

Статья посвящена проблеме исследования индивидуально-типологических особенностей участников киберспортивных игр. Раскрыта специфика киберспорта как новой социокультурной практики, показана актуальность развития психологии спорта как междисциплинарной области знания. Рассмотрены основанные направления исследований психологических характеристик киберспортсменов : анализ позитивных и негативных эффектов влияния занятий киберспортом и компьютерных игр на физическую активность и психологическое здоровье, выявление мотивов игры, когнитивных и личностных характеристик киберспортсменов. Показано, что исследования индивидуально-типологических особенностей киберспортсменов, в отличие от представителей традиционных видов спорта, являются малоизученными. Их выявление и описание позволит определять склонность к определенным дисциплинам киберспорта, разрабатывать психологические основания повышения результативности тренировочной и соревновательной деятельности киберспортсменов с учетом их индивидуальности, предупреждать психологические риски занятия киберспортом. На основании результатов эмпирического исследования свойств нервной системы, типологических характеристик темперамента, самооценки волевых качеств определена специфика проявления индивидуально-типологических характеристик киберспортсменов в зависимости от класса игр. Установлены взаимосвязи между индивидуально-типологическими свойствами киберспортсменов, мотивами заняния киберспортом и характеристиками киберспортивной деятельности. Составлены типологические портреты представителей трёх классов киберспортивных игр: «Шутеры», « MOBA » и «Файтинги».
Психология в сетевом контексте: начальный период
Authors: Войскунский Александр Евгеньевич
Published: April 2020

Рассмотрен начальный период, или предыстория развития психологических исследований в 1970-е и 1980-е годы, результатом которых стала впоследствии современная психология Интернета, или киберпсихология. Представлены ведущие научные проекты, выполнявшиеся в то время в СССР (а именно, в академическом Институте психологии в сотрудничестве с Калифорнийским университетом в Сан Диего и на факультете психологии МГУ), рассмотрены вероятные причины неуспеха т.н. сетевого проекта, выдвинутого в 1960-е годы и лоббировавшегося в течение более чем двух десятилетий пионерами кибернетики в СССР: проект предполагал построение компьютерных сетей. Проводившиеся в рассматриваемый период исследования рассматриваются в контексте тех разработок, которые проводились заграницей (в частности, исследовательского направления «опосредствованное компьютером общение»). Заинтересованность психологов в проведении исследований с участием пользователей глобальных и локальных компьютерных сетей связывается с особенностями культурно-исторической психологии, выдвинутой Л.С. Выготским и распространенной среди отечественных психологов. Этим же объясняется тот факт, что впоследствии психологи первыми среди гуманитариев проявили значительный интерес к изучению специфики применения Интернета широкими массами пользователей.

Повторное использование и хранение компонентой базы планируется обеспечить путем создания репозитория компонентов, архитектура которого представлена в статье. Рассмотрено представление интерфейса на основе моделе-ориентированного подхода по уровням Abstract UI, ConcreteUI, FinalUI и проиллюстрированы переходы между уровнями модели. На основе репозитория в дальнейшем планируется разработка эволюционного алгоритма генерации пользовательских веб-интерфейсов.
Researches about curves sketching on the perspective of global interpretation of figural units focusing on high school
Authors: Pasa Bárbara Cristina , Moretti Méricles Thadeu
Published: April 2020

A teaching approach based on the global interpretation of figurative properties prioritizes the curve sketching and understanding from the conversions among algebraic, graphical and linguistic registers, more precisely the identification of basic units (graphical, symbolic and linguistic) and the verification of how they related with each other. Raymond Duval presents this approach in an outline work of a related linear function using a resource for the global interpretation of the parameters of the algebraic expression: , emphasizing the relationship between these parameters and the graphical visual variables: inclination direction, tracing angles with the axes, and tracing position relatively to the vertical axis origin. Other authors have proposed works under this perspective with a focus on High School. Among them: Moretti (2003), for the quadratic function; Silva (2008), for the exponential, logarithmic and trigonometric functions; Menoncini & Moretti (2017), for the modular function; Martins (2017), for curves whose expressions are in parametric form; Moretti, Ferraz & Ferreira (2008), for more complex functions of college teaching; and Pasa (2017), for polynomial functions of the second and third degree. In this article, we present these works, complementing Pasa & Moretti (2016), presenting the resources used in each of them that allow changing verifications which the graph changes generates in the algebraic expression and vice versa and the identification of the visual variables and units related to the modifications.
Mathematical Forms in the Look about the Human Body: Thought, Technique, Art and Education
Authors: Kerscher Mônica Maria , Flores Cláudia Regina
Published: April 2020

This article is an analytical exercise on a way of thinking in which mathematics operates in the ways of representing and speaking about human body drawing. With a problematic attitude, one asks: how and where does a technique that colonize ways of representing and looking at the body in art and math activities in the classroom come from? This means analysing a modulation of look and thinking that organizes the imagetic representation of the human body, shapes the image, and orders thought, in which mathematics operates as the agent and effect of a mode of colonization. Therefore, it takes different ways of representing the body in art history, operating in a theoretical-methodological movement, with “the perspective of visuality for visualization in Mathematical Education”. Thus, other possibilities of (re) thinking with images are raised, analysing them under the bias of a decolonial mathematical thought, that is, a thought that questions and denounces the effects of truth and the hegemonic mathematical visualities. From this, then reinventing itself to re-exist in Mathematical Education.
Flipped Classroom in Human Anatomy Teaching and Learning: Performance Analysis and Perceptions of Health Academics
Authors: Bandeira Scheunemann Camila Maria , De Almeida Caroline Medeiros Martins , Lopes Paulo Tadeu Campos
Published: April 2020

Contemporary pedagogical practices have undergone restructuring and paradigm shifts; in this scenario, hybrid teaching emerged, which has as one of its modalities the flipped classroom. This study, of a mixed and exploratory nature, the objective was to investigate the impact of the flipped classroom on academic performance in human anatomy and the students' perceptions of this methodology in their teaching and learning in this discipline. Participants were human anatomy students from health courses at a private university in the metropolitan region of Porto Alegre/RS. A didactic intervention was carried out through the flipped classroom methodology, including the study of the urinary and reproductive systems, where the previous material was made available through two digital hypertexts and in the classroom, digital albums were built. Data were collected through pre and post-test questionnaires, with open questions or Likert scale and analyzed through response scores and content analysis. Participants demonstrated better post-test performance by providing more insight into related content. As for the perceptions, they highlighted the contribution of the flipped classroom to their learning and emphasized as their main positive points their contribution to learning, understanding and memorization, as well as allowing greater interaction and cooperation among colleagues. The most salient negative points were the lack of teacher exposure and the permanence of doubts.

Authors: Al-Shukri S.Kh. , Borovets S. Yu. , Rybalov M. A.
Published: April 2020

The study objective is to evaluate the effect of the UltraFertile Plus micronutrient complex on parameters of the ejaculate in men with idiopathic infertility.

Materials and methods. The study included 45 men aged between 24 and 48 years (median 31 years) suffering infertility in marriage. All patients took 2 capsules of UltraFertile Plus once a day in the morning at breakfast for 3 months. The patients didn’t receive any other therapy during the study. Hormonal status, spermogram parameters, MAR test, number of sperm with fragmented DNA using flow cytofluorometry with monoclonal antibodies were analyzed prior to treatment and after it.

Results. After a course of UltraFertile Plus therapy, significant improvement of spermogram parameters was observed in the majority of patients. Sperm count increased from 43.5 to 62.0 million/ml (p < 0.001), percent of progressive motile sperm (categories А and В) increased from 29.3 to 44.4 % (p <0.001), normal morphology sperm count increased from 3.0 to 4.0 % (p <0.001). Administration of UltraFertile Plus promoted a decrease in the number of sperm with fragmented DNA from 14.7 to 10.1 % (p = 0.001) and was effective for patients with this parameter below 22 %. No significant effect of UltraFertile Plus was observed in MAR test. Plasma total and free testosterone levels significantly increased as a result of administration of UltraFertile Plus.

Conclusion. Administration of the UltraFertile Plus micronutrient complex promotes a decrease in sperm DNA fragmentation, an increase in sperm count, percentage of progressive motile sperm and normal morphology sperm, testosterone level.

The authors declare no conflict of interest.

All patients gave written informed consent to participate in the study.
Data Fit (Stress) vs. Model Fit (Recovery) in Multidimensional Scaling
Authors: Borg Ingwer
Published: April 2020

The paper studies the relation of data fit (Stress) and model fit (recovery of a true latent configuration superimposed with random error) depending on the number of points and the error level in the data when running ordinal and interval MDS. Using 2-dimensional MDS with 6 to 100 points and ten levels of error, it is found that adding more points (given that n>10) is driving up the Stress of the MDS solutions but also leads to better recovery, in general. The recovery exceeds any reasonable statistical benchmarks, i.e. more points enable MDS to smooth out the error in the data so that the true configuration can surface more clearly in the MDS solution.
Pond Becomes a Lake: Challenges for Herders in the Himalayas
Authors: Poudel Jiban Mani
Published: April 2020

Climate change is disturbing the existing functional relations between socio-ecological systems in the Himalayan region of Nepal. In this paper, I look at the disturbance posed by climate change to the social and ecological dimensions, referencing the Himalayan herders as eye-witnesses. I focus on two thematic areas, that is, the challenges faced by the mountain herders in the context of climate change and their coping strategies. This paper is a product of nine months of ethnographic study between the years 2012 and 2018 conducted at the Nhāson valley. The herders' stories are “real stories” with insights into the climate variability and fluctuation, which is critically valuable to understand the environmental phenomena at a time when scientific evidence is not enough. In this context, an ethnographic study can contribute in documenting the place-specific and culture-specific stories as the powerful evidence to climate change and how it impacts the grounded social and ecological systems.
Another Climate Change Story: Looking Upstream
Authors: Singer Merrill , Baer Hans A.
Published: April 2020

The applied anthropology of climate change seeks to bring the anthropological lens to the study of and social response to life on a warming planet. Recently, Practicing Anthropology published a special issue on Storying Climate Change! Here, we provide a critique of this set of papers from a political economic perspective based on the assertion that a threat of the magnitude of contemporary climate change warrants a more fully mobilized anthropological response than the local narrative approach called for in the special issue. Specifically, we argue that local stories of climate change experience are knotted together by the reigning global political economic system of capitalism and that this is a story we need to tell to build a sustainable future.

As such, we started the Sausage of Science podcast for the Human Biology Association in order to feature early career professionals, highlight the exciting and highly relevant work done in our field, and talk with our friends and colleagues in a more casual manner for the world to hear. This paper describes how the podcast came about as well as our production process. Furthermore, we discuss why this form of science communication and outreach is critical for the field of anthropology and a public engagement road map for others with podcasting aspirations.

Background: The active development of commodity-transport ties makes the issues of the influence of the situation on commodity markets on the directions and structure of freight traffic particularly important. Scientific understanding of the prospects for the development of transport communications in order to increase the efficiency of goods distribution in accordance with the growing requirements of the economy for its speed, reliability and cost allows us to determine economic indicators for the development of transport infrastructure and the need for investment in fixed assets of transport companies.
Aim: Development of methodological tools for assessing the impact of commodity markets on the processes of updating fixed assets of a transport company.
Methods: The methodological basis of the study is the work of domestic and foreign scientists, which examined the formation of a system of economic indicators - indicators of the state of technical means and systems, the problems of the development of railway transport in the context of macroeconomic changes, as well as the features of innovative activity in railway transport. To solve the tasks, the method of system analysis, methods of statistical analysis, methods of technical and economic calculations, etc. were used.
Results: A methodological approach to the determination of economic indicators reflecting the need for investment when updating the fixed assets of a transport company is proposed taking into account the dynamics of the transport market.
Conclusion: The economically feasible renewal of fixed assets of railways not only plays an exceptional role in creating the conditions for the efficient use of their production resources and their development in general, but also helps to create conditions for satisfying solvent demand in the transport market.

Published: April 2020

Background: Linear motion devices for industrial machines and robots are expected to realize their high efficiency drive and simple structure. Usually, a feed screw mechanism composed of a rotary motor and a ball-screw or slide-screw is employed. However, it has some problems such as the decrease of the drive efficiency, flexibility against external forces, noise, etc. Various linear actuators and motors have been developed utilizing the feature of a direct drive.
Aim: In this paper, we propose a novel linear actuator which 2 movers can be independently controlled using 3-phase and 6-phase superimposed currents for decreasing the size and weight of the system. The proposed linear actuator is driven by the operating principle of a vernier motor which is expected to achieve a high thrust force density per permanent magnet volume.
Methods: The operating principle and the static thrust force characteristics of the proposed linear actuator are verified by an electromagnetic field analysis using 3-D finite element method, and the back electromotive force characteristics are also analyzed. In addition, the dynamic characteristics under position feedback control are analyzed. The control system uses a vector control using PID controller, and the control input is given by the 3-phase and 6-phase superimposed currents.
Results: The static force characteristics were investigated. From the analyzed results, the force interference between the two movers was small. Moreover, the interference of the back electromotive force of the 3-phase and 6-phase movers were not observed. The movers could be independently driven under position feedback control using 3-phase and 6-phase superimposed currents. The dynamic characteristics analyses showed that the mover well followed a target position. From a step response, the time constant and the response of the position feedback system were investigated.
Conclusion: This paper presents a linear vernier actuator with two movers. The basic structure and operating principle of the actuator were described. Moreover, the static characteristics and the dynamic characteristics under position feedback control were analyzed. It was found that the movers can be independently driven.
Improvement of the method of determining dangerous voltage in adjacent lines of communication under magnetic influence of a tracing AC system

Published: April 2020

Background: Currently, there are obstacles on the railways of the Russian Federation for the widespread introduction of a new method of grounding the contact network supports, namely, there is no theoretical and experimental assessment of the electromagnetic effect of the AC traction network on adjacent communication lines when using the contact network supports as natural grounding conductors.
Aim: Improving the methodology for determining hazardous voltage in adjacent communication lines under the magnetic influence of the AC traction network.
Methods: The article discusses the magnetic effect with two fundamentally different grounding systems for AC contact poles - a traditional grounding system on a traction rail network and a system without grounding a contact network poles on a rail network (using fittings and foundations of contact network poles as natural grounding conductors).
Results: The paper shows the disadvantage of the existing methodology for calculating the dangerous voltage in cable lines under magnetic influence, which has a number of serious assumptions that do not allow an objective picture of the magnetic effect on adjacent lines in the presence of a group ground wire. Based on the existing methodology, an improved mathematical model has been developed that allows one to determine the specified values of the dangerous voltage in adjacent communication lines by taking into account the actual length of the group ground cable during operation of the traction network without grounding the supports on the traction rail network. The obtained values of hazardous influences are compared with standard values in the short circuit mode and forced mode. An assessment of the magnetic effect on adjacent communication lines with a traditional grounding system and a system without grounding the supports of the contact network to the traction rail network is given.
Conclusions: The magnetic effect of the traction power supply system of alternating current using poles as natural grounding conductors is less than when using the grounding system of poles of a contact network on a rail network.

Una política fiscal adecuada permite que el gasto, la inversión y las finanzas públicas de los gobiernos a cualquier nivel territorial, sean eficientes y consecuentemente permite que los niveles de crecimiento económico se incrementen. A nivel departamental, Boyacá desconoce la influencia que tiene la recaudación de impuestos municipales en la distribución espacial y dimensional de la actividad económica. Este desconocimiento limita al departamento, constituir una mejor política de desarrollo regional; por ello el objetivo de este trabajo, es establecer medidas que valoren las relaciones del recaudo de impuesto predial per cápita en la actividad económica y los ingresos corrientes per cápita en la eficiencia fiscal de la región. La información para el desarrollo de este trabajo es tomada del Geo Portal del DANE y del Servicio Estadístico Nacional (SEN), siendo todos los datos del año 2016. La metodología empleada se basó en la detección de autocorrelación espacial con la utilización del estadístico I de Moran y c de Geary, se incluyeron modelos de econometría espacial, de donde se establecieron las relaciones funcionales de acuerdo al objetivo de este trabajo. Como conclusiones principales, se obtiene que el impuesto predial per cápita se relaciona negativamente con los niveles de crecimiento económico y se resalta la importancia del incremento de ingresos corrientes para mejorar la eficiencia fiscal.
