River Buffer Effectiveness in Controlling Surface Runoff Based on Saturated Soil Hydraulic Conductivity
Authors: Suryatmojo Hatma , Kosugi Ken’ichirou
Published: September 2021

In tropical Indonesia, rainforests are managed by an intensive forest management system (IFMS). The IFMS has promoted selective logging for timber harvesting and intensive line planting to enrich the standing stock. The implementation of the IFMS has reduced the forest canopy cover, disturbed the surface soil, changed the soil hydraulic properties, and increased direct runoff and soil erosion. Investigation of the IFMS impact on soil hydraulic properties and the generation of surface runoff using a saturated hydraulic conductivity model is needed. Soil hydraulic properties were investigated on 11 plots, including one virgin forest plot and 10 plots at different operational periods of the IFMS. A two-dimensional saturated soil water flow simulation was applied to generate surface runoff from different periods of the IFMS. The main parameters of canopy cover, net rainfall, and saturated hydraulic conductivity were used in the simulations. A simulation scenario of a surface runoff hydrograph in different forest operations was used to analyze the river buffer effectiveness. The results showed that fundamental IFMS activities associated with mechanized selective logging and intensive line planting have reduced the soil hydraulic conductivity within the near-surface profile. The recovery time for near-surface Ks on non-skidder tracks was between 10 and 15 years, whereas on the skidder tracks it was more than 20 years. Forest disturbances have altered the typical surface hydrological pathways, thereby creating the conditions for more surface runoff on disturbed surfaces than on undisturbed surfaces. Maintaining the buffer area is an effective means to reduce the peak discharge and surface runoff in the stream channel.

Published: September 2021

In this study, Yulin city and Yan’an city in northern Shaanxi Province were taken as the study area. Based on the diurnal dry–wet events abrupt alternation index DWAAI, the joint probability distribution of two characteristic variables of “urgency” and “alternation” of dry–wet events abrupt alternation was established by using copula function, and the characteristics of dry–wet events abrupt alternation were analyzed. DWAAI was calculated from daily precipitation data and the applicability of the index was verified. On this basis, the two characteristic variables of “urgency” and “alternation” were separated, and the appropriate marginal distribution function was selected to fit them, and the correlation between the two variables was evaluated. Finally, the appropriate copula function was selected to fit the bivariate of each station, and the joint cumulative probability and recurrence period of the two variables were calculated. The results show that the DWAAI index is suitable for the identification of dry–wet events abrupt alternation in the study area. Light and moderate dry–wet events abrupt alternation occurs more frequently, while severe events rarely occur in the study area. The frequency of severe dry–wet events abrupt alternation in Jingbian station and its northern area is greater than that in the southern area, and the risk of dry–wet events abrupt alternation of disasters in the northern area is higher. The greater the degree of “urgency” and “alternation”, the greater the joint cumulative probability and the greater the return period. The return period of severe dry–wet events abrupt alternation was more than five years, while the return period of light and moderate dry–wet events abrupt alternation was less than five years.
Aquifer Response to Stream-Stage Fluctuations: Field Tests and Analytical Solution for a Case Study of the Yangtze River in Wuhan, China

Published: September 2021

In this paper, field hydrological monitoring tests and an analytical solution for the aquifer response (i.e., the groundwater head) to stream-stage fluctuations are presented through a case study of the Yangtze River in Wuhan, China. A sinusoidal equation for the stream water level over time is proposed and is verified by the monitoring results. Based on the classical 1-D solution of ground water flow equations, a new flow model was proposed to analyze the confined aquifer response to stream-stage fluctuations. The groundwater head of the confined aquifer can then be calculated by embedding the proposed sinusoidal equation of the stream-stage fluctuation into the new flow model. Field monitoring data of the three hydrological years from 2017 to 2019 were compiled to evaluate the proposed model. The results show that the predicted groundwater head of the confined aquifer matches well with the monitoring data. The prediction error of the proposed model (about 8%) is much lower than that of the previous model (about 26%). This paper presents an improved analytical model with a satisfying capability to predict the response of the groundwater head of the confined aquifer to stream-stage fluctuation. This model can be applied into groundwater flow models (such as MODFLOW, FEFLOW, etc.). The results of this study provide a valuable hydrological resource for underground practical engineering in the riverside area, especially in the first terrace of the Yangtze River, and for the dewatering design of a foundation pit in a riverside area.
Deriving Six Components of Reynolds Stress Tensor from Single-ADCP Data
Authors: Bogdanov Sergey , Zdorovennov Roman , Palshin Nikolay , Zdorovennova Galina
Published: September 2021

Acoustic Doppler current profilers (ADCP) are widely used in geophysical studies for mean velocity profiling and calculation of energy dissipation rate. On the other hand, the estimation of turbulent stresses from ADCP data still remains challenging. With the four-beam version of the device, only two shear stresses are derivable; and even for the five-beam version (Janus+), the calculation of the full Reynolds stress tensor is problematic currently. The known attempts to overcome the problem are based on the “coupled ADCP” experimental setup and include some hard restrictions, not to mention the essential complexity of performing experiments. In this paper, a new method is presented which allows to derive the stresses from single-ADCP data. Its essence is that interbeam correlations are taken into account as producing the missing equations for stresses. This method is applicable only for the depth range, for which the distance between the beams is comparable to the scales, where the turbulence is locally isotropic and homogeneous. The validation of this method was carried out for convectively-mixed layer in a boreal ice-covered lake. The results of computations turned out to be physically sustainable in the sense that realizability conditions were basically fulfilled. The additional verification was carried out by comparing the results, obtained by the new method and “coupled ADCPs” one.
Leaching and Transformation of Film Preservatives in Paints Induced by Combined Exposure to Ultraviolet Radiation and Water Contact under Controlled Laboratory Conditions
Authors: Schoknecht Ute , Mathies Helena , Lisec Jan
Published: September 2021

Stormwater from urban areas can transport biocidally active substances and related transformation products from buildings into the environment. The occurrence of these substances in urban runoff depends on the availability of water, and on ultraviolet radiation exposure that causes photolytic reactions. In a systematic laboratory study, painted test specimens were exposed to either ultraviolet radiation, water contact, or a combination of both. Leaching of the biocidally active substances carbendazim, diuron, octylisothiazolinone, terbutryn, and selected transformation products of terbutryn and diuron were observed under various exposure conditions. Remaining concentrations of these substances in the paint were quantified. It was demonstrated that the distribution of active substances and transformation products in eluates and in the coatings themselves differs with exposure conditions. Strategies for environmental monitoring of biocide emissions need to consider the most relevant transformation products. However, environmental concentrations of biocidally active substances and transformation products depend on earlier exposure conditions. As a consequence, monitoring data cannot describe emission processes and predict expected leaching of biocidally active substances from buildings if the data are collected only occasionally.
CT Scans of Asbestos Cement Pipes as a Reference for Condition Assessment of Water Mains
Authors: van Laarhoven Karel , van Steen Jip , van der Hulst Frank , Hernandez Delgadillo Hector
Published: September 2021

The water distribution network of The Netherlands contains around 30,000 km of asbestos cement (AC) pipes, which constitutes around 25% of the total network. As a pipe material, AC has a relatively poor performance, and therefore is a high priority for renewal. To help decide an effective order of replacement, the water utilities need condition assessment techniques that help them determine which pipes have the highest risk of failure. In the presented work, X-ray computed tomography (CT) was used to measure the degradation of AC pipes taken out of the field. These scans provide a description of the pipe degradation with unmatched detail. The results are compared with strength tests performed on the same pipes, revealing that detailed knowledge of the complete pipe degradation is more important than previously assumed. Moreover, comparison of the CT results to those of a commercial, non-destructive inspection technique was used as a new avenue for validation of this technique, demonstrating its future usefulness for attaining the detailed measurement of pipe degradation required by water utilities.

The geometry and the hydraulic properties of the unsaturated zone is often difficult to evaluate from traditional soil sampling techniques. Soil samples typically provide only data of the upper layers and boreholes are expensive and only provide spotted information. Non-destructive geophysical methods and among them, electrical resistivity tomography can be applied in complex geological environments such as volcanic areas, where lavas and unconsolidated pyroclastic deposits dominate. They have a wide variability of hydraulic properties due to textural characteristics and modification processes suh as compaction, fracturation and weathering. To characterize the subsurface geology below the golf course of Bandama (Gran Canaria) a detailed electrical resistivity tomography survey has been conducted. This technique allowed us to define the geometry of the geological formations because of their high electrical resistivity contrasts. Subsequently, undisturbed soil and pyroclastic deposits samples were taken in representative outcrops for quantifying the hydraulic conductivity in the laboratory where the parametric electrical resistivity was measured in the field. A statistical correlation between the two variables has been obtained and a 3D model transit time of water infiltration through the vadose zone has been built to assess the vulnerability of the aquifers located below the golf course irrigated with reclaimed water.

Published: September 2021

This paper presents a novel framework comprising analytical, hydrological, and remote sensing techniques to separate the impacts of climate variation and regional human activities on streamflow changes in the Karkheh River basin (KRB) of western Iran. To investigate the type of streamflow changes, the recently developed DBEST algorithm was used to provide a better view of the underlying reasons. The Budyko method and the HBV model were used to investigate the decreasing streamflow, and DBEST detected a non-abrupt change in the streamflow trend, indicating the impacts of human activity in the region. Remote sensing analysis confirmed this finding by distinguishing land-use change in the region. The algorithm found an abrupt change in precipitation, reflecting the impacts of climate variation on streamflow. The final assessment showed that the observed streamflow reduction is associated with both climate variation and human influence. The combination of increased irrigated area (from 9 to 19% of the total basin area), reduction of forests (from 11 to 3%), and decreasing annual precipitation has substantially reduced the streamflow rate in the basin. The developed framework can be implemented in other regions to thoroughly investigate human vs. climate impacts on the hydrological cycle, particularly where data availability is a challenge.

Published: September 2021

The study of the use of compound feed with shelled and unshelled sunflower seeds in the rearing of broiler chickens is of scientific and practical interest. The purpose of the research was to assess the influence of the inclusion of sunflower kernels and seeds in compound feed on the productivity of broiler chickens. In accordance with the set purpose and objectives of the research the experiment has been carried out on broiler chickens of the Arbor Acres cross from the daily age to the 35-day age under the conditions of the LLC “Morozovskaya Poultry Farm”. For the experiment, 5 groups of broiler chickens with 100 heads in each have been formed. The planting density, light and temperature conditions corresponded to the recommendations for growing broilers of this cross. The broilers of the control group have been received the main diet, and the poultry of the experimental groups have been received compound feed with kernels (5,0–7,5 %) and seeds (5,0–7,5 % + the enzyme drug Ronozyme VP 250 g/t) of sunflower. The results of studies on the inclusion of sunflower kernels and seeds in the diets of broiler chickens have been presented in the article. Data on zootechnical indicators of rearing, results of slaughter and anatomical cutting of carcasses, as well as economic indicators of meat production have been presented. The livability of broiler chickens both in the control and in the experimental groups was at a high level and did not depend on the inclusion of the tested ingredients in the compound feed. It has been found that the inclusion of both 5–7,5 % of sunflower kernels and 5–7,5 % of sunflower seeds with husk in the diet of broiler chickens in combination with the enzyme preparation Ronozyme (250 g/t) contributes to increasing the productivity of poultry, reducing the cost of compound feed, which allows increasing the level of profitability of meat production by 1,9–3,2 %.

La pente du naturalisme
Authors: Andler Daniel
Published: September 2021

Les sciences cognitives sont passées, en un demi-siècle, d’une configuration dans laquelle les neurosciences ne jouaient au mieux qu’un rôle marginal, à une configuration dans laquelle elles occupent une position centrale, voire hégémonique. Comment expliquer un pareil renversement ? L’article complète les explications courantes – difficultés du paradigme classique, progrès spectaculaire des neurosciences nourri par le développement de la neuro-imagerie... – par la prise en compte de la pression exercée par l’exigence de naturalisation : l’étude du cerveau apparaît aujourd''hui, comparée à l’approche classique, comme une voie rapide et sûre vers la naturalisation de l’esprit. Il s’agit là d’une fausse évidence, qui repose sur l’idée que nous savons en quoi consiste la naturalisation d’un domaine avant d’en avoir largement engagé la réalisation scientifique effective. Une fois dissipée cette illusion, on retrouve une perspective équilibrée sur le domaine, tant dans son développement historique que dans son état présent.
Le cerveau comme virtuel incarné
Authors: Sarti Alessandro , Barbieri Davide
Published: September 2021

Dans ce travail nous souhaitons analyser l’évolution des modèles différentiels du cerveau qui sont sous-jacents à toute activité de perception et de cognition. Les contraintes différentielles – la distribution des forces, des différences et des tensions – constituent le virtuel de la morphodynamique cognitive, s'actualisant dans la perception/cognition. Notre champ d'interêt concerne notamment l'évolution des modèles des profils récepteurs des cortex sensoriels primaires, à partir des premiers modèles géométriques, où ils apparaissent comme des opérateurs différentiels, en passant par les modèles basés sur les techniques d’apprentissage automatique, où ils se configurent comme des noyaux de convolution, jusqu’aux théories qui introduisent le conditionnement valoriel du sujet. Par la reconstruction de cette évolution du virtuel, nous chercherons à comprendre comment les modèles neuromathématiques glissent vers des processus de signification, qui ont lieu après l'incarnation du virtuel. Nous ouvrirons par la suite un débat épistémologique sur le rôle et les limites de la modélisation neuroscientifique des processus de signification.
A Brief Survey on the Sociolinguistic Pattern of Khelma (Sakachep) in Relation to the Mediating Role of Multilingualism among the Native Speakers
Authors: Bhattacharyya Pushpa Renu
Published: September 2021

Languages play a vital role in the formation of identity of a speech community with its unique features. The degree of usage of a language in various domains and the positive attitudes of the native speakers towards the language help to strengthen up and maintain the status, power and solidarity of the speech community. Very often the native speakers of the smaller known languages remain unaware of the risk of losing their language or about the process of language shifting. Today in the world of science and technology each and every speech community is practising multilingualism either directly or indirectly according to the demands of the basic needs in their daily lives. This paper is a result of an attempt to present a sociolinguistic survey on the language use, attitude and identity of native speakers of Khelma (Sakachep) in the district of Dima Hasao, Assam in North-East India towards their mother tongue as well as towards other languages spoken and used in different domains in the Khelma community according to their needs. The research work is carried out under CFEL, Tezpur University, Assam. Native speakers based on different age groups, gender, educational qualifications, occupational patterns, family types and as rural and urban dwellers were interviewed. The methods used for interview were personal interviews, group discussions, telephonic conversations and silent observations. The participants were asked a series of questions concerning their language, culture, traditions and also their feelings regarding other languages used in and around them.

Though spring snail Marstoniopsis insubrica is widespread in Europe it has been rarely recorded in Ukraine yet only in the northwestern part. Newly found specimen of M. insubrica in the central part of Ukraine (Olshanka River, middle part of the Dnieper basin) extending the south-eastern limit of the species distribution range. All known records of M. insubrica in Ukraine are restricted to several isolated occurrences and snails are occurring solitary. As of today only few specimens accumulated in the Ukrainian museums collections over the century. It evidences this is regionally extremely rare species. Considering rarity, populations’ low-density and occurrences on a very edge of the species natural range M. insubrica we recommend to include this species into the next edition of the Red Data Book of Ukraine with an endangered conservation status.

Published: September 2021

This paper summarizes the mechanisms behind the patterning of the intra-population spatial arrangement of the land snail Vallonia pulchella in terms of edaphic and vegetation properties. The molluscs were collected from a regular grid in recultivated soil (the research station of Dnipro State Agrarian and Economic University, Pokrov, Ukraine). As predictors of the snail population abundance, spatial variables were used, as well as edaphic and vegetation indices. It is shown that V. pulchella prefers microsites characterized by higher soil electrical conductivity, which contain larger aggregate fractions with low mechanical impedance and the low temperature at the depth of 0-10 cm, with a more developed dead plant layer, low-light and low hygromorph and heliomorph index values of the vegetation.

Published: September 2021

37 species of the land molluscs were identified in the material collected in 2002-2017, many being earlier unknown from Zaporozhye region. In total 39 species of molluscs can be considered as reliably recorded from this region. The presence of some species is the result of anthropochory. This concerns first of all those land snails which have spread from the Crimea: Brephulopsis bidens, B. cylindrica, Phenacolimax annularis, Oxychilus deilus, Monacha fruticola, Xeropicta derbentina, X. krynickii, Eobania vermiculata, Helix lucorum. One species (Xerolenta obvia) was introduced to Zaporozhye region from the western part of Ukraine. The data obtained made it possible to clarify the current distribution of Helicopsis retowskii and Chondrula tridens martynovi over the territory of Ukraine.
Spatial distribution of land molluscs fauna of the steppe zone of Ukraine
Authors: Gural-Sverlova N. V.
Published: September 2021

At the end of the XX - beginning of the XXI century 85 species of the land molluscs of 49 genera and 25 families were reliably registered in the steppe zone of Ukraine. The highest species richness was recorded in the northern steppe subzone (79 species). The main centers of the species diversity are the Donetsk Upland (65% of the total number of species) and the western part of the Black Sea Lowland with the southern spurs of the Podolian Upland adjoining it (55%). The modern composition of the land molluscs fauna of the steppe zone is influenced by the proximity of the Caucasus (for the south-east of Ukraine), the Podolian Upland (for the north-west Black Sea coast) and the Crimea (for the entire investigated territory). Anthropochory plays an important role in the formation of the land molluscs complexes in the steppe zone of Ukraine.

Published: September 2021

Morphological and optical properties of tentacular epidermis and cornea of the eyes of some species of terrestrial gastropod pulmonate molluscs were studied and their evolutionary transformations were estimated. It was demonstrated that all examined properties of tentacular epidermis and cornea of these species are typical for terrestrial pulmonates. In the course of evolution tentacular epidermis of terrestrial pulmonate molluscs was modified to less extent than cornea, and both these structures underwent minor changes in comparison with analogous structures of the eyes of marine prosobranch molluscs.
On the phylogenetic relationships of Elbasania Schileyko et Fehér, 2017 (Pulmonata, Helicoidea, Hygromiidae)
Authors: Neiber Marco T.
Published: September 2021

The genus-group taxon Schileyko et Fehér, 2017 has recently been introduced as a subgenus of Metafruticicola Ihering, 1892 for a species occurring in north-western Greece and Albania. Using mitochondrial and nuclear markers, the phylogenetic relationships of Elbasania within Metafruticicolini (Hygromiidae) are reconstructed. The results of these analyses suggest that Elbasania is more closely related to Hiltrudia Nordsieck, 1993, which has a range adjacent to that of Elbasania from Croatia to northern Albania, than to Metafruticicola. Elbasania shares with Hiltrudia and also Cyrnotheba Germain, 1929 a very characteristic microsculpture of the shell and an overall similar genital system, which however differs among these three taxa with regard to its internal structures, especially those of the penis. Therefore, it is suggested regarding Elbasania as a distinct genus here.

Geographical and chronological variability of the conchological characters of the mollusc Fruticicola fruticum (O.F.Müller, 1774) (Gastropoda; Pulmonata; Bradybaenidae) in the Eastern Europe
Authors: Snegin E. A. , Snegina E. A.
Published: September 2021

The population structure of the terrestrial mollusk (Gastropoda, Pulmonata, Bradybaenidae) in different landscapes of Eastern Europe on the basis of conchological measurements, including morphometric parameters and color variants was studied. For all morphometric parameters used, statistically significant differences were found between the studied populations. At the same time, the shell size are determined not by zonal characteristics, but by microbiotopic conditions. Changes in the frequency of shell phenotypes in Fr. fruticum populations are probably of a multifactorial nature. The ratio of different color variants can be caused by the influence of radiation, cyclic fluctuations of climatic factors, succession changes in biotopes, and gene drift.

A turboprop engine is a hybrid engine that delivers thrust or jet thrust and also drives the propeller. This is basically similar to a turbojet except the turbine works through the main shaft which is connected to the reduction gear to rotate the propeller in front of the engine. This research was conducted to determine the development of engine performance in thermodynamic analysis so as to know the value of each parameter on a engine that has been developing for 20 to 50 years with different engine manufacturing. So that in this study a comparison of the thermodynamic analysis of the TPE-331, PT6A-42 and H85-200 engines was carried out. In the TPE331-10, PT6A-42, and H85-200 turboprop engines the value of fuel to air ratio and shaft work increases with increasing altitude while compressor work, fuel flow rate, shaft power, propeller thrust, jet thrust, total thrust, equivalent engine power and ESFC decrease with increasing altitude. Furthermore, the turbine's working value is relatively stable as the altitude increases. After that, the value of compressor work and turbine work on the PT6A-42 engine was greater than that of the TPE331-10, and H85-200 engines. However, the value of the fuel to air ratio, fuel flow rate, shaft power, jet thrust, equivalent engine power and ESFC on the H85-200 engine was greater than the TPE331-10 and PT6A engines. Furthermore, at sea level, the value of the axle, propeller thrust, and total thrust on the H85-200 engine is greater than that of the TPE331-10 and PT6A-42 engines but at an altitude of 25,000 ft, the PT6A-4 engine has a greater value than that of the TPE331-10 and PT6A-42 engines. TPE331-10, and H85-200 engines.

Tropical cyclones (TCs) are the most destructive weather systems that form over the tropical oceans, with 90 storms forming globally every year. The timely detection and tracking of TCs are important for advanced warning to the affected regions. As these storms form over the open oceans far from the continents, remote sensing plays a crucial role in detecting them. Here we present an automated TC detection from satellite images based on a novel deep learning technique. In this study, we propose a multi-staged deep learning framework for the detection of TCs, including, (i) a detector - Mask Region-Convolutional Neural Network (R-CNN), (ii) a wind speed filter, and (iii) a classifier - CNN. The hyperparameters of the entire pipeline is optimized to showcase the best performance using Bayesian optimization. Results indicate that the proposed approach yields high precision (97.10%), specificity (97.59%), and accuracy (86.55%) for test images.

Authors: Bendrath Eduard Angelo , Reis Jaqueline Rocha dos
Published: September 2021

INTRODUÇÃO: O programa de Residência Pedagógica é um modelo de formação profissional para cursos de licenciatura, sendo um programa integrado a Política Nacional de Formação de Professores, cujo intuito está no aperfeiçoamento prático por meio da inserção do acadêmico no ambiente escolar. Este programa surgiu com inspiração na Residência Médica, sendo esta uma modalidade de ensino de pós-graduação destinada a médicos já graduados, como forma de especialização clínica. OBJETIVO: Analisar as aproximações e distanciamentos entre o programa na área da Educação Física em relação ao programa da área médica a partir da percepção de coordenadores das áreas de uma universidade pública do Paraná. MÉTODOS: A pesquisa é caracterizada como de abordagem qualitativa, com foco no estudo de caso. Foram entrevistados 4 coordenadores de curso e de programa de residência vinculados aos cursos de Medicina e Educação Física. A análise dos dados foi baseada no princípio de categorização temática com foco na análise de conteúdo. RESULTADOS: Os resultados mostram que há diferenças significativas entre as propostas, tendo a residência médica uma formação em nível de pós-graduação enquanto a residência pedagógica uma formação inicial, isso reflete as definições estruturais e conceituais sobre a forma de inserção de tais modelos formativos no ambiente de atuação profissional. CONCLUSÃO: Conclui-se que o propósito de formação em licenciatura com base em modelos de residência profissional possibilitam novas experiências e caminhos, mas que ainda estão distantes do modelo ofertado na área médica.

Published: September 2021

INTRODUÇÃO: A Educação Física é a disciplina do currículo escolar que aborda a cultura corporal, com a finalidade de introduzir e integrar o estudante a essa esfera do conhecimento, formando o cidadão que vai produzir, reproduzir e transformar essa cultura. Possibilitar experiências diversificadas no âmbito das práticas corporais e fortalecer a participação dos estudantes nas aulas são fatores fundamentais no desenvolvimento da disciplina. OBJETIVO: Este relato que tem como objetivo apresentar e discutir a proposta de oficinas temáticas nas aulas de Educação Física escolar, a partir das opiniões de estudantes do ensino fundamental 2 e médio de uma escola pública federal no município de Niterói (RJ). MÉTODOS: Se caracteriza como uma pesquisa qualitativa crítica que utilizou como registro, as respostas dadas por aproximadamente 160 estudantes nas avaliações da disciplina, que, além de nortear a tomada de decisão para a realização das atividades, constituiu o corpo da investigação que ora apresentamos. RESULTADOS: Percebemos que as oficinas temáticas possibilitaram a ampliação dos conhecimentos e vivências relacionados à cultura corporal e uma maior maturidade na relação dos estudantes com a disciplina, com os colegas das diferentes turmas e com a professora. CONCLUSÃO: Foi perceptível a modificação da percepção dos estudantes sobre a Educação Física escolar, bem como ampliação da consciência crítica, colaborando com desenvolvimento da cidadania.

OBJETIVO: Apresentar um resgate das estratégias de aproximação com a rede de educação básica, desenvolvidas pelo Programa de Educação Tutorial da Educação Física (PET/ESEF), objetivando sinalizar sua contribuição na formação docente para atuação no campo da Educação Física escolar, destacando a trajetória de atuação profissional dos egressos. MÉTODOS: A pesquisa qualitativa foi realizada com dois eixos de coleta dos dados. Em um eixo foi realizada busca documental de relatórios, atas e mídias sociais referentes a 30 anos de história do PET/ESEF. Já no segundo eixo, o processo de coleta dos dados, realizado no ano de 2020, envolveu a identificação dos egressos a partir de informações disponibilizadas na Plataforma Lattes e mídias sociais, com foco na sua área de atuação e formação. Os dados coletados foram analisados de forma descritiva visando a constituição das duas categorias de análise: a) Descrição das ações e estratégias voltadas para a docência e; b) Percursos profissionais e de atuação docente. RESULTADOS: As ações apresentaram diferentes propostas de intervenção e vivências na escola, considerando as possibilidades da cultura corporal e a área da Educação Física. Os egressos tiveram contato com escolares de diferentes faixas etárias, devido às dinâmicas organizadas ao longo das ações, o que pode ter contribuído para seu crescimento profissional. Além disso, no decorrer da análise do percurso profissional dos egressos, identificamos que a grande maioria realizou cursos de pós-graduação, sendo esta entendida também como incentivo do programa. CONCLUSÃO: O PET/ESEF dentro das diretrizes propostas pelo programa contribui para a formação diferenciada dos membros que o compuseram. Uma parcela importante tem atuação na rede de educação básica, outros, atuam ou atuaram como docentes do ensino superior, e ainda, tem privilegiado o espaço da pós-graduação para seu aprimoramento humano e profissional.

INTRODUÇÃO: O Programa Residência Pedagógica objetiva aperfeiçoar a formação prática nos cursos de licenciatura, proporcionando uma imersão do acadêmico na escola de Educação Básica. OBJETIVO: Relatar as experiências vivenciadas por uma residente nos primeiros seis meses do Programa Residência Pedagógica de um curso de Educação Física, frente aos desafios da pandemia de COVID-19 para a formação inicial docente. MÉTODOS: O programa foi realizado em uma escola-campo na cidade de Ourinhos (SP) e contou com a participação de 10 residentes que desenvolveram atividades para alunos do 4º e 5º ano do Ensino Fundamental. O cronograma do primeiro módulo foi dividido em três etapas: (A) ambientação, (B) observação estruturada e (C) regência. RESULTADOS: A pandemia de COVID-19 resultou em um processo de regência através do ensino remoto, o que causou certa insegurança e a adaptação do ponto de vista da residente autora. Entretanto, a preparação das etapas de ambientação e observações auxiliaram de forma efetiva a construção do processo de regência. A regência foi dinâmica e encorajadora, e incentivou a atuação no âmbito da Educação Física Escolar. CONCLUSÃO: Apesar das dificuldades encontradas no ensino remoto, todas as experiências vivenciadas pela autora deste relato durante o primeiro módulo do programa contribuíram de forma crucial para a sua formação inicial.

OBJETIVO: Apresentar a proposta de planejamento e a construção de uma prancha de equilíbrio para o ensino das Práticas Corporais de Aventura para alunos dos anos finais do ensino fundamental, no contexto do ensino remoto. MÉTODOS: Foi elaborado a partir da Disciplina Estágio Supervisionado em Educação Física Escolar II, desenvolvida no 2° semestre de 2020, do curso de Licenciatura em Educação Física da Universidade Federal de Santa Catarina. texto considera a análise conjuntural da Educação Física no ensino remoto e da unidade educativa que serviu de base para se estruturar este planejamento. A proposta de intervenção foi pensada buscando considerar os conteúdos yoga e meditação que estavam sendo trabalhados pela professora da turma. RESULTADOS: Destaca-se que o conteúdo Práticas Corporais de Aventura surgiu a partir de um levantamento prévio feito com os estudantes sobre conteúdos que tinham interesse em aprender. Foi planejado um conjunto de cinco módulos de conteúdos para duas turmas do nono ano da escola-campo. CONCLUSÃO: Conclui-se que essa experiência pedagógica proporcionou aos envolvidos um conjunto de aprendizados significativos para o incremento da prática pedagógica docente. E que, a ausência do contato mais efetivo com os estudantes e com a realidade da escola-campo impactou a experiência formativa dos graduandos em Educação Física.
El desempeño,la privaticación,los profesionales de la educación y el estado
Authors: Ball Stephen
Published: September 2021

Este artículo discute y analiza tres aspectos de la política educativa; estos aspectos son: i) el desempeñoentendido como la tecnología y la forma de regulación y reglamentación que utiliza juicios, comparaciones y demuestra como medidas de· la productividad o de resultados la valoración de individuos y de organizaciones; ii) la privatización, entendida como la utilización de distintas formas de mercado para reformar las instituciones públicas del sector educativo, (privatización endógena) o la presencia de proveedores privados que ofrecen servicios educativos (privatización exógena); iii) los cambios en las formas y modalidades en la cual el estado, se transforma de un gobierno, (burocracia y administración) a un control (ejercido por empresas y redes). En el centro de esta infraestructura de la política coloco al profesor, al maestro. - al profesional de la educación- como sujeto de la reforma educativa. Clasifico también, de forma amplia, tres distintos tipos de literatura y, lo que destaco con mayor importancia, asumo una posición personal dentro de una intersección caracterizada por incitaciones y seducciones inmersas en la reforma del sector educativo
