Sentido y alcances prácticos de la Educación Física Escolar como un Derecho Humano.Análisis en las Bases Curriculares chilenas de Educación Básica
Authors: Oliva María Angélica , Beltrán Hernaldo Carrasco
Published: December 2020

RESUMEN Resumen Se analiza la Educación Física Escolar como un Derecho Humano en las Bases Curriculares de Educación Básica en Chile. Se utiliza una metodología hermenéutica/dialéctica en 2 corpus -Bases Curriculares Nacionales de Educación Física y Salud y marco jurídico de Derechos Humanos- mediante una estrategia documental y un análisis de contenido inductivo. Se concluye que la Educación Física Escolar podría constituir un Derecho Humano, por su defensa de la dignidad, no discriminación, respeto a la diversidad, entre otros. Sin embargo, en el proceso de diseño curricular los Derechos Humanos pierden la presencia que poseen en las Bases Curriculares Nacionales, debido a la circunstancia política de su enunciación y a la carencia de un Enfoque Basado en Derechos Humanos (EBDH).

ABSTRACT The goal of this study is to identify the influence of the maturity state in the physical components of the high level youth male soccer players of an elite club in Brazil. Eighty-seven young male soccer players participated in this study, distributed in 34 U-14 players, 23 U-16 players and 30 U-19 players. Peak height velocity (PHV) was estimated: Pre-PHV (<-1.0 years, n=13), mid-PHV (-0.99 to 0.5 years, n=41), and post-PHV (>0.5 years, n=33). Running-based anaerobic sprint test, squat jump, yo-yo and 30m speed test were performed. The results of this study suggest that the maturational development influences vertical jump. VO2max, yo-yo test distance, fatigue index and power. This information is essential for the identification and effective development of talented football players.
EVALUATION OF THE POSITIONAL QUALITY THROUGH THE POST-PROCESSING OF RAW GNSS DATA FROM A SMARTPHONE VIA DIFFERENT SATELLITE POSITIONING METHODS
Authors: Gomes Allan , Krueger Claudia Pereira
Published: December 2020

Abstract: Since the introduction of the Android 7 in August 2016, it has become possible to use raw data collected by GNSS sensors present in some Android smartphones and tablets. Therefore, it became possible, for the first time, to perform the post-processing of the data, which means to obtain coordinates that are more accurate than usual, from meters to decimeters. In addition, among the technological innovations in the context of positioning via smartphones, it is mentioned the use of modern GNSS sensors, like the one used by Xiaomi Mi 8, which was the first smartphone to integrate a dual-frequency GNSS sensor. In this research, data collection campaigns were carried out in static mode to evaluate the quality of geodetic coordinates obtained from Mi 8. Using freely available applications that store raw data in files in RINEX format, the data was post-processed with different positioning methods and with different software, including the freely available IBGE-PPP online service in Brazil. The results of this research show that it is possible to obtain geodetic coordinates with an accuracy at decimeter order, which indicates that the methodology can be used in some engineering applications.

Published: December 2020

All concrete structures contain reinforcement spacers, and deep sections can be affected by bleeding and segregation without displaying visible indications during casting. However, their effects on mass transport and long-term durability are not well studied. In this paper, reinforced concrete columns were prepared with plastic and cementitious spacers to achieve 50 mm cover, and compacted at different vibration frequencies and durations. 28d cured samples were extracted along the height, conditioned to equilibrium (21 °C, 75% RH or 50 °C, 7% RH), and then subjected to water absorption, electrical conduction, epoxy impregnation and fluorescence imaging. Samples from the top of the column consistently gave higher accessible porosity and mass transport compared to samples from the bottom. Presence of spacers caused additional increases in mass transport because of preferential flow through the spacer-concrete interface which is more porous and microcracked compared to bulk concrete farther away. Image analysis on cross-sections showed that the columns experienced some aggregate segregation despite care taken to avoid over-compaction. The resistance of concrete to ingress of aggressive agents decreases with increasing height due to the combined negative effects of reinforcement spacers and segregation.
Wildfires in Northern Portugal: an operational case study in Tabuaço
Authors: Rodrigues André , Ribeiro Carlos , Reis Johnny , Sousa Miguel , Raposo Jorge
Published: December 2020

The present work is an analysis of the wildfire that occurred in Tabuaço (Portugal). This wildfire developed in a complex topography and under extreme meteorological conditions. The wind was one of the most difficult factors because it increased the rate of spread of the fire front and increased the number of spot fires in front of the head fire. This kind of situation is very often a source of incidents or accidents. Additionally, the fire progressed in zones where the wildland–urban interface was practically non-existent, but also in the areas where the existence of settlements gave rise to critical points, related to the necessity to protect people and property. The suppression manoeuvres of the fire of Tabuaço were carried out in a way that led to a high level of safety, without victims or serious injuries recorded, and so they can be considered an example of a wildfire fighting approach. The use of fire to fight a fire is an important technique when it is well applied. An analysis of the existing conditions, such as geographic characteristics, meteorological situation, topography, fuels and infrastructures of defence against forest fires and fire development and behaviour, are described and analysed in a detailed way.

Published: December 2020

Flax is a prominent natural fiber used in biodegradable and sustainable polymeric biocomposites as reinforcement material. The prime objective of this research was to fabricate, characterize and compare flax-woven-fabric-reinforced poly(lactic acid) (PLA) and polypropylene (PP) with different directions (lengthwise and cross-wise) by using hot-press technology. Tensile strength, elastic modulus, flexural strength, flexural modulus, thickness swelling and water absorbency tests were carried out to assess the physical and mechanical performance of the composites. The flax/PLA composites exhibited the highest tensile strength (128.6 MPa) in the lengthwise direction, whereas flax/PP showed the lowest tensile strength in the cross-wise direction (90.69 MPa). Flax/PP had the highest flexural strength (53.80 MPa) in the lengthwise direction, although flax/PLA (lengthwise) provided the maximum bending modulus (40.809 MPa). Moreover, scanning electron micrographs were also investigated to observe the appearance of the matrix for flax/PLA and flax/PP composites before and after applying tensile loads. Fourier transform infrared spectroscopy analysis indicated successful lamination of flax woven fabrics with the thermoplastic polymers (PLA and PP). Thermogravimetric investigation showed enhanced thermal stability of the produced biocomposites.
Allegorical Aĭdaḣar: An Animated Look at Kazakh National Identity
Authors: Zawlacki Jake
Published: December 2020

The little-known Kazakh animated film, Why the Swallow’s Tail is Forked (1967), written and directed by Amen Khaydarov, not only holds the position as the first example, but is also acclaimed as the greatest work of Kazakh animation by critics, academics, and contemporary animators. The film, based on the traditional Kazakh folk tale of the same name, was significantly altered by Khaydarov in his auteurist direction resulting in a radical retelling. Despite these alterations, Khaydarov’s variant of the folk tale resonated with viewers of the period as well as today. In this paper I argue how certain motifs are changed, added, and removed from the original folk tale by Khaydarov, consciously or unconsciously, to incorporate new allegorical elements in the folk tale. This essay takes an “animated look” at the film in that it performs a close reading of a folk tale through a film medium. After performing a shot by shot analysis, I deconstruct alleged “traditional” Kazakh elements, then analyze the dreamlike nature of pastoral national identity, the interplay of film, written, and spoken folklore, and the rhizomatic structure of folklore through audio and visual elements. Ultimately, I return to the film and display it as a construction of a specific nationalist narrative thus shedding light on the broader pastoral nationalist vision.

Published: December 2020

Introduction. The intensity of tool wear, as an increment of wear to the cutting path, characterizes one of the important processing indicators. It is used in the development of algorithms for controlling the cutting process, including the calculation of trajectories in CNC machines. As the cutting speed increases, there is a value at which the wear rate is minimal. It corresponds to the optimal value of heat production in the cutting zone, that is, the power of irreversible transformations of the energy supplied to cutting. Heat production depends on the dynamic system parameters that change along the tool path. In this regard, at the initial stage and during processing, it is necessary to coordinate the control with the properties of the dynamic cutting system. Subject. The paper offers a study and analysis of the relationship between the tool wear rate and the dynamic properties of the cutting process, and on this basis, the definition of technological modes in which the wear rate is minimal. The purpose of this work is to study the dependence of the tool wear rate on the initial and changing dynamic properties of processing along the path, and to create on this basis methods for matching technological modes with the current cutting dynamics to reduce the wear rate. Method and methodology of the work. In this paper, experimental and analytical methods are used to study the evolutionary changes in the properties of the system in relation to the development of tool wear. The developed mathematical models of the cutting system are presented, which differ from the known ones in that the power of irreversible energy transformations of the mechanical system in the interface of the back faces of the tool with the workpiece is additionally modeled. The dependence of the wear rate on the power of irreversible transformations, that is, on a given time interval in the increment of wear, is given. This takes into account the dependence of wear on the dynamic properties of the cutting system, including during its evolution. Results and discussions. It is shown that the properties of evolution are sensitive to small variations in the parameters of the dynamical system. These variations make significant changes in the wear rate. The paper reveals the dependence of wear on the properties of a dynamic system, that is, on its parameters, technological modes, beats, and other perturbations. Conclusions. The disclosure of the dependence of wear resistance on the dynamic properties of the cutting process characterizes new ideas about the factors that affect wear resistance.

Published: December 2020

A  Mycena species new to science was obtained from moist chamber cultures of trunk bark of a living American elm tree (Ulmus americana) located in the Fort Worth Botanic Garden, Tarrant County, Texas. This discovery was part of an ongoing study of corticolous myxomycetes on larger American elm trees occurring in Fort Worth nature parks. More than 15 American elm trees were sampled for trunk bark but only a single tree yielded  Mycena basidiomes. Collections of bark began in the summer of 2017 and continued until the beginning of 2020. Bark samples from the north, south and west side of the tree yielded fruit bodies of the mushroom in moist chamber culture. No fruit bodies were observed in nature nor were early formation stages on the underside of the bark. Crystals previously described in another study were present on the bark surfaces, edges, and undersides. Habit and morphological development were photographed using light microscopy applying multifocal imaging and computer stacking to increase depth of field. Basidiome development was observed and photographed from the earliest primordial beginning stage, the button stage, intermediate stage and the final emerging stalk elongation and mature cap formation stage. Mature mushroom development took from 9 to 21 days after wetting the bark in moist chamber cultures. Scanning electron microscopy was used to illustrate development of the button stage, emerging stalk and pileus stage, and the fully mature pileus, lamellae, and pseudocollarium. Morphological features and DNA sequence data confirmed that this  Mycena species was undescribed and distinct from other  Mycena taxa. Morphological features suggest placement of the novel taxon in  Mycena sect. Viscipelles, distinct from other members based on morphological characters and phylogenetic analysis.
Modelling producer behaviour in fixed route private transport services
Authors:   Department of Economics, Hansraj College, University of Delhi, India, Hazarika Ishan Kashyap
Published: December 2020

Objectives: While fixed route private transport services have grown in prominence in the recent times, there is a dearth of models that specifically tackle pricing in it. The current study aims to model producer behaviour in this model, keeping in mind its peculiar physical characteristics. Methods: This study develops a rational-actor model of the behaviour of producers operating in this market. There is however, an added assumption of the heuristic of least perceptible difference to add behavioural realism to the model. Results: The predictions derived from the model developed in this study include repeated usage of a single type of round-trip for a non-zero interval of time, the convexity of expected-waiting time with respect to changes in prices and a negative relation between external (exogenous) demand at one-point of a path and the price charged at the other. Conclusion: Pricing in this market, due to physical factors, can exhibit unique features as modelled. Keywords: Private Transport; transport Pricing; producer behaviour in transport

Iron-based alloys began to be used so long ago that today they are classified as classical materials, since these alloys have been studied in depth. The production of various products from steel and cast iron naturally takes the first place in terms of volume, since they have a valuable set of properties: a wide range of plasticity and strength, unique technological properties, which makes it possible to apply all technological operations to them - from simple casting into earth to complex pressure treatment processes. This combination of properties provides, first of all, the composition of iron-based alloys with the main alloying element – carbon. The serious disadvantage of ferrous alloys is their low level of corrosion properties. To eliminate this drawback, both steel and cast iron are alloyed with such metals as chromium, nickel, cobalt, etc. Naturally, this leads to an increase in the mass of finished products and structures. Therefore, the search for alloying elements to improve and optimize the composition of ferrous alloys is relevant today. On the other hand, the industry of Uzbekistan produces a sufficient amount of transition, rare earth metals. Thus, the task is to get added value from the production and processing of these non-ferrous metallurgy products. The analysis of the known literature data on this topic shows that research has been carried out on the use of various transition and rare earth metals for alloying ferrous alloys. However, the available scientific results do not allow to speak about systemic knowledge about the use of rare earth and/or transition metals as effective additives for steels and cast irons. The authors studied phase equilibria, determined the compositions of the phases and the reactions occurring in the systems, constructed phase diagrams, their isothermal sections, determined the structure of iron-based alloys with additions of rare-earth and transition metals with all structural components. The prospect of using the products of nonferrous metallurgy of Uzbekistan for the production of high-quality steels and cast irons is shown.
Two approaches to the analysis of spatial and temporal organizations of a literary work (M.M. Bakhtin and V.M. Zhirmunsky)
Authors: Filatov A.V.
Published: December 2020

This article examines two methodologies for analyzing a literary work. The first one was developed by M.M. Bakhtin on the basis of a broad aesthetic and philosophical approach; the second one was developed by V.M. Zhirmunsky on the basis of a more specific formal and poetological approach. These methodologies were applied by both researchers to A.S. Pushkin’s poems in the 1920s. It is argued that Bakhtin’s methodology was worked out in opposition to the main provisions of Zhirmunsky, who was close to the position of Russian formalism, also taking into account L.V. Shcherba’s achievements in the field of the linguistic analysis of a poetic text. This article describes the fundamental differences in the methodological conceptions of the philosopher and the literary critic concerning the nature of verbal creativity and understanding of the spatial and temporal organization of a literary work. The comparison of two analyses of Pushkin’s poem “For the Shores of Distant Homeland…”, shows that Zhirmunsky reduces the spatial and temporal aspects of a work of art to the compositional arrangement of verbal and sound material, since he considers verbal creativity as a linguistic phenomenon, while Bakhtin refers to the space and time of aesthetic reality, drawing a distinction between the composition and the architectonics of the literary work. It appears that the philosopher perceives the work as a field of dialogue between various subjects of consciousness (the author, the characters, the reader), while the literary critic proceeds from the author’s primacy as creator of a system of artistic techniques, giving the reader a position of passive perception. It is concluded that both methods of analysis complement each other organically, Zhirmunsky analyzing the verbal-compositional dimensions of a literary work and Bakhtin its objective-architectonic dimension.
PANCREATIC CANCER, CURRENT THERAPEUTIC APPROACHES AND POSSIBLE PROSPECTS

Published: December 2020

Prevalence of pancreatic cancer (PC) is not high in the population, but the aggressive nature of the disease leads to the fact that PC is one of the main causes of death in a group of patients with cancer. The prognosis for PC is significantly worse in the case of metastatic spread. It is proved that pancreatic adenocarcinoma from the very beginning is a systemic disease with early micrometastatic spread, so the question of effective drug treatment is extremely relevant. Chemotherapy is the basis for the treatment of patients with metastatic prostate cancer. However, despite numerous clinical studies using known cytostatic and targeted agents, progress in the treatment of this disease remains relatively modest compared to the progress made in the treatment of other types of tumors. The complexities of prostate cancer therapy are explained by the presence of a dense connective tissue tumor stroma, which is not just a barrier to tumor cells. It has a significant impact on various vital cellular processes, including tumor formation, invasion, metastasis, and contributes to the formation of drug resistance. Pancreatic cancer is heterogeneous in terms of molecular and biological characteristics. Many genetic changes, including germ lines and somatic mutations, contribute to the development of this disease. Recent studies have shown that each sample of prostate cancer includes an average of 63 genetic changes and 12 major signalling pathways. Further studies of tumor microenvironment markers and decoding the heterogeneity of the tumor genome in PC should become the basis for a “personalized” approach to treatment.

THEORETICAL ANALYSIS OF THE MODEL OF PROFESSIONAL SELF-DETERMINATION OF THE FUTURE SOCIAL WORKER
Authors: Bodrova І.
Published: December 2020

he article discusses the provisions of research on the problems of models of professional self-determination. The approaches of scientists to understanding the essence of the concepts of "self-determination", "professional self-determination" are analyzed.

The relevance of the topic is due to the fact that the system of professional training of future specialists is not sufficiently aimed at the formation of a specialist as a person and professional with a certain set of personal qualities, values, knowledge, abilities and skills. There is growing interest not only in the development of the theory and practice of social work, but also in the personality of a professional, his features and qualitative characteristics.

This work is an attempt to generalize the existing models of professional self-determination and to reveal the specificity of the circumstances of such self-determination for the sphere of social work, as a separate case of self-determination, acquires specific features due to the conflict of individual features and ideas of the future social worker about himself, his role and status in the communities surrounding the individual , about society (formed by cultural norms) and individual factors that are characteristic of this field of activity.

The article used such research methods as the method of theoretical analysis, modeling, abstraction.

As an approach for analyzing the structure of the act of self-determination, we used the model proposed by P.G. Shchedrovitsky in works on positioning / self-determination / self-identification.

The analysis of the phenomenon of professional self-determination through the prism of this model of the act of self-determination made it possible to single out the specifics of the main groups of factors relevant to the process of professional self-determination of a future social worker.

Published: December 2020

The article deals with gender specificity (similarities and differences) in the management activity of men-leaders and women-leaders of social sphere institutions. The practicability of taking into account this specificity in practice has been substantiated. Several methods have been used in the study, in particular, the method of questioning the heads of social institutions. In order to analyze the data, a comparative approach has been used to identify the similarities and differences in the managers of social institutions on the basis of gender, as well as to determine the set of leadership qualities for the head of this sphere according to current managers' opinion with many years of experience. Studying the experience of the participants in this study provided a number of recommendations for current and potential managers who are in search of formal leadership in order to increase the effectiveness of social protection of vulnerable population. It is important to work on your own career development program, which implies constant activity in the current state of management, pursuit of greater achievements, constant self-development, search for those areas of development that are stimulating. The second recommendation refers to planning for the future - that is a strategic plan for the development of the organization or institution you manage. It is important to consider each achievement as a prospect for continuous improvement and advancement. The next recommendation addresses persistence and resilience as a self-defense against the risk of failure, adverse and critical conditions for activity. It is important to fight against negative stereotypes and gender-based discrimination. In this respect it is important for women to be able to demonstrate the consequences of their efforts, so that the success rate will testify to their ability and skills. The following recommendation is about the importance of personal support through mechanisms such as mentoring, strong female examples, and training by outstanding leaders.

Authors: C Arulmurugan , A Yatheesh
Published: December 2020

Background: Inadequate evidence is found about dyslipidaemia from smoking in India. The jeopardy of dissimilar medical complications is regularly reflected as augmented in the circumstance of cig burning. The pervasiveness amongst countryside and town Indians of beedis and tobacco often gives rise to the occurrence of coronary artery illnesses. Aim: the study aims to assess the variation of lipid profile and dose-related vicissitudes among the non-smokers and smokers by assessing the number of daily amount of beedis and cigarette’s. Materials and methods: We performed a cross sectional investigation for a period of one year in our hospital. The participants of this study were mostly of age 15-55 and their BMI is below 25. Patients suffering from medical illness were excluded from the study. Our study included 100 non-smokers and 200 smokers. We conducted a semi-structured interview in a form of questionnaire to collect material about smoking habits and diet. Serum samples were collected upon twelve hours of fasting to estimate the lipid profile. The collected serum was centrifuged and 3 ml of blood kept in a vial for lipid profile estimation. Results: All the lipid variables except HDL-C were found high among smokers when compared to the non-smokers, while in the smoker group the HDL-C levels were lower than non-smokers and statistically important differences were observed. Likewise, most lipid parameters are favourably associated to the numbers of pack years, with the increase in triglyceride level, total cholesterol levels, LDL, VLDL being statistically important, and a clear negative association between HDL-C and pack years. Conclusion: The study concluded that there is a variation in lipid variables in the smokers serum such as VLDL, TGs, TC and LDL were elevated and that of reduction in HDL is found. This variability causes adverse cardiovascular events and cerebrovascular disease. Lipid profile should be evaluated in smokers to mitigate the risk of coronary artery and the related disease. They will be briefed on the health risks of smoking. They should be convinced to leave cigarette consumption to healthier lifecycle and embrace better lives.

Avaliar a associação entre variáveis socioeconômicas e relacionadas a saúde bucal no suporte social percebido por gestantes. Esse estudo transversal incluiu uma amostra obtida em conglomerados de gestantes atendidas no serviço público de saúde no sul do Brasil. As gestantes responderam questionários acerca de características demográficas, socioeconômicas e relacionadas à saúde bucal. O suporte social foi avaliado através da escala Medical Outcomes Study. As variáveis clínicas incluíram cárie dentária não tratada e sangramento gengival. Análise de Regressão de Poisson em multinível foram utilizados para avaliar a influência dos preditores no suporte social. A amostra foi composta por 254 gestantes. Gestantes com pior autopercepção de saúde bucal, níveis extensivos de sangramento gengival e com menor nível socioeconômico apresentaram um pior suporte social. Fatores socioeconômicos e relacionados à saúde bucal exerceram impacto no suporte social percebido por gestantes.

ABSOLUTE CHRONOLOGY OF UPPER VOLGA-TYPE POTTERY: MORE EVIDENCE FROM ZAMOSTJE 2

Published: December 2020

Zamostje 2, on the Dubna River, c.100km north of Moscow, appears to offer an ideal opportunity to understand the relative and absolute chronology of Upper Volga Early Neolithic pottery. More than 100 radiocarbon (14C) dates are available from a stratigraphic sequence which spans from the Late Mesolithic to the Middle Neolithic. All typological stages are represented among over 18,000 sherds of Early Neolithic pottery, and many of these sherds bear deposits of carbonised food remains (food-crusts), which can be dated directly by 14C; more than 30 food-crusts have been dated directly. Nevertheless, there remains considerable uncertainty about the date range of Upper Volga pottery at Zamostje 2, and many of the issues raised are relevant to dating early pottery at other sites. Moreover, the absolute chronology of Upper Volga pottery must have some bearing on the interpretation of 14C dates for pottery from adjoining regions. In this paper, we discuss alternative interpretations of the Zamostje 2 evidence.
FIRST IMPRESSIONS OF EARLY NEOLITHIC RUSSIAN POTTERY TECHNOLOGY
Authors: Spataro Michela
Published: December 2020

Ceramics appeared in southern Russia at about the same time as in southern Europe, at ca. 6000 cal BC, but whilst pottery was introduced into southern Europe, together with plant and animal domesticates, from southwest Asia, early Neolithic pottery in eastern Europe was probably developed locally by hunter-gatherers, or derived from other pre-agricultural societies in northern Eurasia. In this paper, four sherds from four different regions of central and southern Russia are analysed using the same methods previously employed in two large-scale research programmes on early Neolithic pottery from the Adriatic and the central Balkans. The four pots were made with different tempering agents and were generally low-fired, but while they may represent different technological traditions to the southern European pottery, the overall technical quality of the hunter-gatherer pottery is no less developed than that of the early farmers.
