In the exercise of teaching, teachers give account of different forms of organization: emerging, self-managed and autonomous product of conceptions that arise from training, performance and experiences where the socio-political nature of both his being and individual that integrates and makes part of social groups, as in the exercise of professional practice. Under this horizon, the aim of this work is to analyze from the social function of the teacher the sociopolitical role of their task as far as the political vision has, ability to understand social problems and generate actions for which is part of a frame of reference where the concepts that allow to develop theoretical analysis to identify the sociopolitical expression of the teaching exercise are exposed, considering that in this practice this type of content is revealed in the teachers as actors of the teaching-learning process, both in the training in their performance based on the training they receive, the historical geographical relationship and the experiences that their activity provides them with what has framed this work. It is concluded that in the exercise of teaching work are present sociopolitical categories that affect both the understanding of social phenomena and the pretense of practical actions that transform these realities from the institution-teacher-student interaction.

We are immersed in a changing and highly complex context. Highly volatile, complex and dynamic markets hinder managers’ role in planning and decision-making enormously. There seems to be a consensus that accelerated innovation could provide an answer to the question, what might the next discovery or advance that breaks the rules of our market be? Or in other words, to use an expression common in management speak, what is “the next big thing”? Disruptive management aims to study the causes of business innovation and how it can be systemized in a company, providing clues to achieving excellence in any given market and a methodology that can be learned by managers for application to all companies. This study describes some of the elements for professional and business adaptation to VUCA environments.
Validez de contenido de una rúbrica analítica del diseño de secuencias didácticas como mejora de la práctica pedagógica del equipo docente desde el enfoque de la socioformación
Authors: Guevara-Rodríguez Guillermina , Veytia-Bucheli María Guadalupe
Published: December 2020

The educational context traditionally determines an administrative practice of planning and evaluation processes, in this sense, there is a lack of instruments to evaluate the design of didactic sequences with the challenge of granting knowledge that confront contextual problems; and make a teaching intervention with methodological bases for solving problems. The purpose of this study is to describe the design of a didactic sequence rubric for the improvement of pedagogical practice. The methodology was carried out through an instrumental study of content validity based on the socioformative approach with the following steps: 1) analysis of instruments at ends; 2) construction of a rubric with the focus of socioformation, 3) revision and improvement of the instrument by experts; 4) application of the instrument to a pilot group; and 5) validation of content by a group of judges in the educational area. The results with respect to the V of Aiken with a significance of p <0.05, show a value above 8.0. Some items whose level of significance was 0.71 were eliminated. The reliability analysis shows a value of Cronbach's alpha of 0.891, the Aiken and Cronbach coefficient methodologies applied, determined the content validity of the rubric. In conclusion, a pertinent instrument to evaluate the design of didactic sequences is presented, and the need to extend this study with an exploratory factor analysis that determines its construct validity is presented.

Este artículo presenta un análisis del estado de la comunicación indígena en América Latina con un enfoque etnográfico y comparativo basado en seis estudios de caso: México, Guatemala, Panamá, Colombia, Bolivia y Argentina. Nuestro estudio se ocupa de la situación de los «paisajes mediáticos», es decir, la proliferación de medios de comunicación tecnológica en cada contexto, sus usos sociales efectivos y sus transformaciones en el tiempo. Para ello destacamos tres aspectos analíticos: 1) las innovaciones en la comunicación indígena, las cuales han pasado de un énfasis en la apropiación tecnológica a la necesidad de su incorporación como valor cultural, así como un cambio de énfasis en la «resistencia» a la idea de «descolonización» de los medios, 2) las características que definen la comunicación indígena, y 3) la constatación de su heterogeneidad e implicación en realidades sociales y políticas concretas y locales.
Agua para unas comunidades y para otras no. Conflictividades y contradicciones en torno al agua para consumo humano en los territorios de Ujarrás y Conte Burica, Puntarenas, Costa Rica
Authors: Mora González Ana Lucía
Published: December 2020

El artículo presenta una primera aproximación al análisis de la relación entre políticas públicas y conflictividades en torno al agua para consumo humano en tres comunidades pertenecientes a dos territorios indígenas de la provincia de Puntarenas: la comunidad de Alto Conte en el territorio indígena ngäbe Conteburica y las comunidades de Ujarrás y Guanacaste, en el territorio indígena cabécar Ujarrás. A partir de lo anterior, el trabajo también evidencia las diferentes formas de gestión social del agua presentes en las comunidades indígenas ante la ausencia de suministro de agua por cañería, así como las contradicciones internas y de distribución ecológica a las que son sometidos los territorios en estudio, lo cual, a su vez, se convierte en riesgos sanitarios y de calidad de vida.

THE GREAT BODY OF SOCIETY: IS THE NINTH CENTURY RETURNING?
Authors: Yermolenko Volodymyr
Published: December 2020

The author of the article puts a question about the limits of the 20th century individualism. He expresses a hypothesis about the cyclic nature of the cultural and political theory. In particular, he draws attention to the rhythm of changes of the hedonistic and ascetic ep- ochs, spiritualist and materialist epochs, individualist and holist epochs. The author ana- lyzes holistic doctrines of the 19th century: philosophies of Fabre d’Olivet, Auguste Comte, Pierre Leroux. Although today almost forgotten, the ideas of these authors can be revived again in the 21st century, he says. Based upon the analysis of the 19th century holism which the author did in his book Liquid ideologies, the author makes a hypothesis that the 21st century is becoming much less individualistic and much less materialistic than the 20th century. The metaphors of the “collective body” and “absolute spirit” are coming back in the 21st century, in the new form of the digital reality.
GLOBALIZATION AND SINGULARITY: transformation of the foundations of modern society
Authors: Proleiev Serhii , Shamrai Viktoria
Published: December 2020

The article is devoted to the transformations of society in the era of globalization. The global world is seen as a consequence of the successful implementation of the world-historical the Project of Modernity. Its completion results in the loss of its intellectual authority and historical effective- ness. The principal quality of contemporary society became its globality. The paradoxical phenomenon of the world, that had ceased to be a reality, became an integrative shape of the global transformations. Visibility took the privileged place here. The degradation of reality is analyzed in its main forms: dematerialization of reality; decline and destruction of human sensory experience; destruction of the alive contacts with living beings and the capacity to empathize with somebody; the loss of the space of the human existence space features of a stable, predictable, structured se- mantic order. The consequence of that is the destruction of the foundations of the communities and society as a whole, which is fixed by the notion of their «vagueness». The correlation to this social metamorphosis is a new anthropological format — the singularity, which provides for the theoretical abolition of identity as a way for defining a man. It means the loss of an individual’s predictability and its determination as a social character. The network is the way through which the singularities interact, and swarms are the natural form of their association. Swarm is a historically new, unstructured, but subordinated to common impulses union, which consists of points of activity of different intensity. The analysis of society is incomplete without taking into account its discursive-communicative nature. In the global world there is a decline in the discourses. The signs of that process are the lack of legitimacy in classical instances of the meaning (truth, good, beauty, etc.), the degeneration of thinking into mixing, changing criteria of significance (dominance of curiosity and impression), social degradation of the media. The main feature of these changes is the latest phenomenon of information power (the power of depersonalized information space and information technology — those modes of circulation and use of information that became a determining factor in human life in the globalized world).

The mathematical model of the magnetoelastic acoustic emission (MAE) signal in the form of a random pulse flow is proposed and substantiated. The pulse and time characteristics of the MAE signal are highlighted. Using the results of the experiment by the MAE method of plate ferromagnetic steel samples an estimation of a number of parameters of the MAE signal is made. As a result, the dependences of the sum of the amplitudes and the final account of the signal from the set threshold for different loads are obtained. The dependence of the final account on the set threshold for the various values of the exponent attached to the sample is approximated. The dependence of the attenuation coefficient of the approximating exponent on the magnitude of the applied to the load sample, which is proposed to be used as a calibration in diagnosing residual stresses in ferromagnetic objects, is constructed.

The estimators of parameters of bi-periodic nonstationary vibration signal deterministic part, obtained with using the least squares method (LSM), are analyzed. LSM estimation allows avoiding aliasing effects. The formulas for estimators of variance and bias, which describe their dependences on realization length and signal covariance components, are derived. The results are specified for the quadrature model of the signal. LSM has shown its efficiency for separation of harmonics with close frequencies, so it should be considered as the main method for vibration signals analysis. It is shown that its usage allows one to obtain unbiased estimators of bi-periodic nonstationary vibration signal deterministic part regardless of realization length and harmonic frequencies.

This is the third article in the cycle of publications on the monopolization level of scientific periodicals of National Academy of Sciences of Ukraine. It is devoted to the journals of Section of Physical, Engineering and Mathematical Sciences. The paper finishes the first stage of research aimed at revealing the breadth of the authors’ community of the NAS of Ukraine journals during 2015–2017. As well as in the previous articles of this cycle, the estimation of the authors’ community and its monopolization level is made by the Herfindahl–Hirschman Index calculation. Thus, the quantitative weighted distribution of affiliation is made for each journal. The analysis of the journals of Section of Social Sciences and Humanities and the Section of Chemical and Biological Sciences is made in the articles previously published in the “Herald of the National Academy of Sciences of Ukraine” (2018, No. 9 and 2019, No. 10). It was shown that the chemical and biological journals of NAS of Ukraine have the lowest monopolization level — there are only 23% of middle-monopolized and 27% of low-monopolized ones. Meanwhile, only 19% of journals of the Section of Social Sciences and Humanities have the moderate monopolization level and the rest have the high one. Journals of the Section of Physical, Engineering and Mathematical Sciences are more like chemical and biological ones. They mostly have high monopolization level (54%), however 17% are moderately monopolized and 25% are low-monopolized.

Authors: Kravtsov Yuriy , Bogomaz Kostiantyn , Sorokina Lyudmila
Published: December 2020

The article assumes an analysis of information as one of the most important socially significant resources of modern civilization. The authors stressed that main paradigm characteristic of modern social theory can be expressed by the thesis about the impossibility of direct access to social phenomena. In modern civilization, information is becoming one of the most important socially significant resources. The authors think that its role as a strategic resource increases with the development of network technologies that accelerate data transfer and facilitate the search for necessary information. The authors are confident that the role of higher education in this process is key. But it itself is faced with a huge number of problems, one of which is improving the quality of its functioning and guaranteeing the results of its activities. This problem is closely related to the implementation of innovations. The authors suggest that innovation in education should be understood as an innovation designed to resolve the current problem situation in order to optimize the educational process, improve its quality or organize favorable conditions for the assimilation of material by students. Based on a critical approach to reform the current system of higher education the paper touches upon the need to change the process infornatization of humanities education.. The authors conclude that the development of humanities education in the information society is aimed at implementing an interdisciplinary approach, ie should ensure the effectiveness of the development and application of humanities knowledge and form a conscious responsible choice in a variety of cultural meanings, cultural self-determination.
Histopathological changes in pigs infected with ileitis
Authors: Yermolenko O.M. , Ayshpur O.Y. , Mushtuk I.Yu.
Published: December 2020

Nowadays, the ileitis (proliferative enteropathy of pigs) is one of the most common gastrointestinal diseases. The intracellular bacterium Lawsonia intracelluaris causes several forms of the disease. Histological examinations are the important stages in diagnosing and detecting profound pathological changes in sick pig organs, decreasing their productivity and causing the deaths. Swine proliferative enteropathy (SPE) has reported for the Ukraine since 2008. For SPE the early diagnostics with different test systems is relevant. We evaluated the sick, forcibly killed and dead piglets of different ages in Ukrainian pig farms during 2018-2019 in animal fattening groups. Materials were taken from piglets aged 120-150 days in farms where the ileitis was diagnosed. To assess the complex of pathological and anatomical changes detected during autopsies of piglets, V.P. Shishkov’s methods were used. Thus, we revealed a characteristic morphology of proliferative lesions. We believed that the histological examination can serve as an important diagnostic method and an alternative to direct isolation of Lawsonia intracellularis, which is very difficult to cultivate. We determined that the histopathological changes in pig organs indicated a chronic effect caused by animal pathogen. We revealed that Lawsonia intracellularis caused the profound pathological changes in pig digestive tracts, which affected the functioning of all organs and tissues of animals and lead to severe disease and possible animal death. We suggested that the histological examination is an important step in diagnosing and detecting profound pathological changes in the organs of sick pigs, which caused the decrease in their productivity and deaths.

Selenium in natural environment and food chains. A Review
Authors: Sobolev O.I. , Gutyj B.V. , Soboleva S.V.
Published: December 2020

The analytical review attempts to summarize the results of numerous scientific research conducted by scientists around the world on selenium scattering and accumulation in natural environment, with considerable attention paid to the concentration of this trace element in soils, natural waters and plants. It is shown that selenium content in agricultural products is caused by the processes of physico-chemical and biogenic migration of this element in the biogeochemical food chain. According to the modern classification of trace elements, which is based on their biological significance for living organisms, selenium belongs to the vital group or biogenic elements. As a biotic element, it has unique physicochemical and biochemical properties and with adequately absorbed into the human body has a positive effect on a number of physiological processes. Various research shows that the majority of the world population (except in some regions) today consumes less selenium with the food than necessary and its consumption decreases every year. Insufficient selenium intake in the human body (less than 15–30 μg/day) leads to the development one of the hypomicroelementosis – hyposelenosis. Selenium deficiency is considered as a possible etiological factor in some cardiovascular, cancer, osteoarticular and neurodegenerative diseases that threaten to human life. Providing the human body with selenium in optimal amounts is one of the important conditions of nutrition. A number of countries have developed recommended selenium intake standards for the adults, which range from 55 to 120 μg/day. We can calculate the physiological need for selenium in children and adolescents by extrapolation. The most safe and effective way to maintain the necessary level of selenium for the human body can be achieved only through the poultry and livestock products by mandatory introduction of premixes containing highly effective biologically available selenium forms into animal feed. This will ensure a relatively high level of trace element in meat, eggs, and milk and would eliminate the cases of toxicosis in human population due to buffer effect of animal tissues.

By carrying out a theoretical synthesis of the information on the regularities of population dynamics of some insect pests of agricultural plants and based on the past and present the authors have analysed the dynamics of many years in the number of the insect populations. An attempt to determine the presence of synchronism of outbreaks of the insects’ mass reproduction with the years of sharp changes in the solar activity has been made; the relationship between the changes in the number of the insects and meteorological and heliographic factors has been analysed. An analysis of the dynamics of the sun pest reproduction taking into account the duration of sunshine on the materials of one of the outbreaks (local population) in the Kupiansk district of the Kharkiv region showed the unreliability of this index as a predicate of the prognosis; and the reproduction rate of the local population of the sun pest does not change depending on the duration of the solar radiance. It is determined that this principle is also unsuitable for forecasting the dynamics in the number of this pest. The linear differential equations, in which not only the meteorological factors but also the indices of the solar activity (global factor) were used as variables were unsuitable for prognostication the dynamics in the number of the insects. The examples listed in the article confirm the fundamental regularity, namely the polycyclic dynamics of various natural systems and the synchronism in their development. The synchronization is inevitable because all objects of inanimate and living nature consist of the same chemical elements, and the conservation and conversion of energy is universal in nature. Based on the methodology of the cyclic dynamics it is possible to develop the algorithms for prognostication the regular mass reproduction of harmful insects.

Published: December 2020

Increasing of crop yields mainly caused by modern technology, use of mineral fertilizers and plant protection products. Therefore, developing of zonal agricultural technologies will ensure the rational use of soil agroclimatic potential and increase grain production profitability. Because of economic needs, the broad use of mineral fertilizers, including liquids with minor nutrient elements was applied in Altai Krai. Therefore, the justification of doses and sorts of fertilizers and minor nutrient elements is especially relevant here. The aim of our study was to increase the efficiency of granular and liquid mineral fertilizers in the cultivation of spring wheat in the steppe zone of Altai Krai. The experiment was done in LLC “Russia” in Novichikhinsky district of Altai Krai. We presents seven fertilizer variants for cultivating the spring wheat using the No-Till technology in the steppe zone of Altai region. We also assessed the quality of sowing, soil water regime, yield structure and grain quality, and presented the general patterns of crop formation and technical and economic evaluation of these fertilizer variants.
Intrapopulation variation in shell morphological traits and banding polymorphism of the land snail Cepaea vindobonensis (Gastropoda; Pulmonata; Helicidae)
Authors: Kramarenko A.S. , Ignatenko Zh.V. , Yulevich O.I.
Published: December 2020

The main goal of this paper was to analyze intrapopulation variation of both morphological traits and shell banding polymorphism using the example of a continuous population (a metapopulation) of the land snail Cepaea vindobonensis (Férussac, 1821). A total of 14 samples of the land snail C. vindobonensis from a population located in the “Dubki” Park (Ukraine, Mykolayiv) were collected in May-July 2007. The land snail collection sites are divided into three areas by buildings and asphalt roads, indicated by the Latin letters A, B and C. The major diameter of shell (MJD), the minor diameter of shell (MID) and the shell height (SH) were measured with a digital calliper to the nearest 0.05 mm. Two shell shape indices (SF1 and SF2) were also computed. A high level of the intrapopulation variation of the land snail C. vindobonensis was found in our study. Significant differences between sample means were found for all shell traits and indices used (except for SF1), however, maximum difference was noted for SH and SF2 (in both cases: P ≤ 0.001). About 80% of the total variation of the variance-covariance matrix was explained by the 1st and 2nd Principal Components (PC1 and PC2). The PC1 was characterized by high positive factor loadings of MJD, MID and SH and thus can be interpreted as “shell size dimension” and the PC2 had a high correlation with SF2 and thus it can be interpreted as “shell globularity”. The PC1 and PC2 determined a high level of spatial differentiation of intrapopulation morphological variation of the land snail C. vindobonensis. Samples with small (area A) and large (areas B and C) shells were separated from each other according to the PC1. Areas B and C were characterized by individuals with flatness and globularity shells, respectively. The areas A, B and C differed significantly in the total number of morphs, average number of morphs and frequency of rare morphs (Kruskal-Wallis H-test; in all cases P ≤ 0.010). At the same time, the highest value of phenetic diversity was noted for samples collected within A and C areas. In general all phenetic diversity estimators showed a positive correlation with sample size (Spearman's correlation coefficient; in all cases P ≤ 0.05). It was found that the type of biotope did not likely affect the frequency of individual morphs with respect to the shell banding polymorphism pattern. With regard to the most common morphs two patterns of the spatial arrangement of the intrapopulation variation were found – clinal pattern was for the frequency of pallescens morph and chaotic pattern was for frequency of “12345” morph.

Published: December 2020

The study presents variability in the qualitative composition and quantitative indicators of secondary mycelium metabolites of the fungus Diaporthe (Phomopsis) helianthi Munt.-Cvet. et al., the most harmful plant pest of Helianthus annuus L. Toxicity of secondary metabolites of D. helianthi was analyzed by determining the average length of seedling shoots of Triticum aestivum L. test object grown on fungus filtrates of different cultivation dates. The maximum toxic effect of D. helianthi was recorded during the germination of Triticum aestivum L. seedlings on a 17-day filtrate of pure mycelium culture of the fungus. The mean length of wheat seedlings in this variant of the experiment decreased by 3.5 times compared with the control and 3.3 times compared with the filtrate of the culture medium of 7 days of cultivation. High-performance liquid chromatography (HPLC) identified secondary metabolites of D. helianthi as fomosin, fomopsolides, cytosporones, and xanthones. There was a redistribution of secondary metabolites due to increase in number of cytosporones, decrease in content of fomopsolides, and termination of xanthone synthesis with increasing time of cultivation of fomopsis mycelium, under conditions of relatively stable indicators of fomosin content.
Designing of a DNA matrix for transgene integration into the bovine beta-lactoglobulin gene locus using CRISPR/Cas9 technology
Authors: Koloskova E.M. , Ezerskiy V.A. , Ostrenko K.S.
Published: December 2020

Beta-lactoglobulin (BLG) is the main protein in milk serum in almost all mammals, with the exception of rodents and primates. Regulatory regions of the beta-lactoglobulin gene in ruminants (sheep, goats, and cattle) as part of genetic constructs provide tissue - specific expression of recombinant protein in the mammary gland and have been actively used in genetic engineering since the beginning of the era of creating transgenic animals. To work effectively with the CRISPR/Cas9 genomic editing method, it is necessary to know the exact DNA sequence of the target gene: this is necessary both for creating a DNA matrix for homologous recombination and for the targeted accuracy of guide RNAs. A polymorphic variant of the bovine BLG gene was identified, whose sperm was used to fertilize cow oocytes in vitro. The aim of this work was to create a plasmid containing 5’ - and 3’ - arms of homology (ha) to the bovine BLG gene. Based on ??TZ57R/T, the pTZhaBLG plasmid was obtained, which has a unique site for EagI restriction at the junction of the homology arms. A fragment containing a biologically active protein gene can be embedded in the resulting plasmid at this restriction site. We created the pBLGcmvEGFP plasmid containing the green fluorescent protein (EGFP) gene under the cytomegalovirus (cmv) promoter: protein expression can serve as a reliable indicator of successful integration of the transgene into the genome. The resulting plasmids in circular or linearized form are intended for site-specific integration by homologous recombination repair into the BLG gene using CRISPR/Cas9 components.

All lines have high and moderate resistance against diseases: Powdery Mildew, Brown Rust, Septoria Blotch. Based on obtained data had selected breeding lines, which were promising sources of single and complex agronomically valuable traits for bread wheat breeding and genetic researches.
Yield and seed structure of the spring wheat
Authors: Belyaev V.I. , Sokolova L.V. , Matsyura A.V.
Published: December 2020

We presented analysis of the influence of spring wheat seeds sowing qualities on the yield. Experimental studies were carried out in 2010-2017 in Altai Krai. The seed divided into fractions in the air stream differs significantly in its characteristics. The ratio of fractions significantly depends on the conditions of the year and has a significant impact on the formation of the potential yield of spring wheat. Seeds isolated at an air speed of 8 m/s are a highly significant limiting factor in achieving the maximum yield of spring wheat. An increase in their share for every 10% in the seed can lead to a yield shortfall of up to 5.5 c/ha. Sowing should be carried out with the most complete seed fractions, with a 1000 grain weight of 31.8-38.0 g, obtained at an air flow rate of 9 m/s. Their share in the seed used by the farms of the region is 34.8 - 52.7%.

Over the course of 2007-2015, the department of the irrigated agriculture had been conducting research in the area of the Ingulets irrigation system on the experimental fields of the Institute of Irrigated Agriculture of the National Academy of Agrarian Sciences of Ukraine (NAAS), which were established in 1996, with the aim to develop and scientifically substantiate agroecological and technological methods for crop rotations on the irrigated lands of the Southern Steppe of Ukraine that will ensure soil fertility, increase crop productivity, economic and energetic efficiency. In 2007-2010, studies were conducted to substantiate the systems of basic tillage using different ploughing tools. The 4-field grain-row crop rotation 1 included winter wheat with post-harvest cultivation of millet, corn, soybeans and spring rape. Five studied systems of basic tillage differed in methods, techniques and the depth of soil loosening. In 2011-2015, grain-row crop rotation 2 entailed soybeans, instead of spring rape seed, and winter barley with post-harvest cultivation of millet, instead of winter wheat. Five studied systems of basic tillage differed in the depth of soil loosening and non-renewable energy costs for their implementation. Experiments were performed under conditions of two organo-mineral fertilizer systems using by-products of crop rotation, fertilizer application in doses of N75P60; N97, 5P60 and inoculation of soybeans with microbial compounds. Following crop rotations 1 and 2, a decrease in humus content within the 0-40 cm soil layer to the level of 1976, 110.2-114.4 t/ha, was observed. To prevent further decline in humus content, an optimization model was developed by capping specific weight of soybeans in short-term crop rotation 25%, stubble plowing the stem and leaf mass of crops as well as applying fertilizer quantities corresponding to the expected yields. With the help of mathematical modelling, it was determined that the retention of post-harvest plant remains in soil and the application of nitrogen and phosphorus fertilizers increased humus content in soil used for growing rape by 0.3%, winter wheat – by 0.7%, and corn – by 0.9%.

Cuerpos que significan en la escena y la pantalla: Imágina (2010), un singular desafío transmedial.
Authors: Salas Murillo Bértold
Published: December 2020

El largometraje Imágina (2010), de Adrián Cordero y Roberto Peralta, ejemplifica una operación de escritura transmediática que ha sido poco explorada por los creadores costarricenses: esa que traslada las formas y los contenidos de un espectáculo de danza, concebido para la escena, a una entidad audiovisual cuyas temporalidad y espacialidad son pensadas para la pantalla. El videodanza de Cordero y Peralta “transpone” tres coreografías de Rogelio López: Prohibido adentrarse en el bosque, Cuerpos de la barra y Homenaje a María Cristina (2007-2010). Esta operación de transposición contó con la participación del mismo coreógrafo, así como de las bailarinas y bailarines del grupo Danza abierta, quienes hicieron parte de la versión escénica de las creaciones. Con el texto audiovisual como punto de partida, este artículo examina la escritura transmediática que lo hizo posible; es decir, una operación de transposición constituida por el encuentro y diálogo de dos medios artísticos con sus materiales, códigos, convenciones y potencialidades particulares. El examen llama la atención sobre los intercambios y las tensiones que emergen de la concurrencia de profesionales de dos disciplinas distintas. Se reconoce finalmente en Imágina la productividad de esta diferencia mediática y disciplinar.

El presente artículo expone una posible interpretación dialéctica para el Estudio Nº 1 del compositor brasileño Heitor Villa-Lobos (Brasil, 1887- 1959). Éste se ubica en el contexto sonoro, cultural y artístico que le es contemporáneo al autor en cuestión. En este trabajo se aborda la tendencia estética y artística de la música popular que rodeó al autor para, posteriormente, reubicar el sentido rítmico del Estudio a través de las nociones de Antropofagia Cultural, Escucha Poscolonial y Oído Etnográfico.
Synergistic Team Teaching for Professional Development: A Case Study Approach
Authors: Ramírez Casalvolone Natalia
Published: December 2020

This study proposes an innovative approach for English professors who lack the time to engage in professional development (PD) programs, believe such programs are conducted in a decontextualized manner, or regard them as too expensive. Based on a qualitative case study performed from January to September 2018, this study addresses the following question: How can team teaching promote PD for mid-career English as a foreign language university professors? It investigates the types of PD that emerged when two English professors at the University of Costa Rica engaged in synergistic team teaching. Theparticipants team taught a course for students newly admitted into the English-teaching major. In this study, synergistic team teaching is understood as a method in which two professors share classroom space and teaching practices and engage in planning discussions together. To understand what the participants learned when practicing team teaching, data were collected through semi-structured interviews and coded following Creswell and Poth’s (2018) data analysis spiral. The coding was developed in light of the conceptualization of PD developed by Guskey (2002), Sparks (2002), and Johnson (2006). Accordingly, thisstudy identifies instances (during the interview or during the classroom observation) that can be interpreted as change of the classroom practices, change in the attitudes and beliefs of the professors (Guskey, 2002), continuous improvement of teaching and learning (Sparks, 2002), and teacher’s knowledge transformed into practice (Johnson, 2006). This study shows how team teaching offers professors a community of practice in which they can share, discuss, and implement new teaching knowledge. Through team teaching, teachers receive PD benefits that match their classroom context perfectly, enabling them to engage in authentic, fully contextualized learning opportunities.

High-altitude tourism is gaining popularity. Mountains are also becoming an increasingly popular destination for school or family trips. This suggests that the number of children with high-altitude diseases, including acute mountain sickness (AMS), will also rise. The aim of this literature review was to determine the epidemiology of acute mountain sickness, its most common manifestations and risk factors in children. We analysed papers from the last 5 years, which were found by two independent authors using PubMed, ResearchGate and Google Scholar. The following keywords were used to identify relevant studies: acute mountain sickness, altitude sickness, children (by Medical Subject Headings). After screening with the exclusion criteria, the final analysis included 5 papers, which were assessed for the quality of evidence. The incidence of acute mountain sickness in children is 30–45% at elevations below 4,000 m. There were no differences compared to an adult population. Headache, sleep disorders and dizziness are the most common symptoms of acute mountain sickness in children. Further research is needed to identify factors that predispose children to this disease. In the light of the increasingly intensive alpine tourism among children, research on the sequelae of acute mountain sickness is recommended.

Modern obstetrics and gynecology use a wide range of medicines (drugs) when accompanied by pregnancy and childbirth (miscarriage, discoordination labor, labor pain relief), diseases of the female reproductive system (inflammation, dishormonal disorders, etc.). Among the traditional drugs most widely used antibiotics, NSAIDs, analgesics, antispasmodics, hormones. These drugs, along with the achievement of rapid and pronounced therapeutic effects cause different side effects, and have a number of contra-indications (diseases of the liver, the pancreas, the risk of thrombosis, the development of immunodeficiency, etc.) [12]. In this regard, special attention and care requires the use of drugs in pregnant women and nursing mothers. Also relevant is the increase of efficiency of treatment of many gynecological diseases. All these and many other factors encourage to search for new – more effective and safer treatment approaches and drugs, including pathogenesis [12,22]. The review presents brief characteristics and clinical researches on the use and integrated bioregulatory approach through the use of complex combination bioregulatory medicines (CBM) Viburkol, Limphomiozot, Limphomiozot N in obstetrics and in various diseases and disorders of the female reproductive system [1–3]. The research results show that the inclusion of one or more of the CBM in the traditional treatment help reduce the duration of therapy, a decrease in some side effects, and in some cases rejection of it. In addition, they do not burden for opportunistic diseases, tolerated well and have a favorable safety profile, can be used during pregnancy and lactation [4–22]. Key words: Viburkol, Limphomiozot, Limphomiozot N, bioregulatory approach, combination bioregulatory medicines, obstetrics, gynecology, diseases of the female reproductive system.
