Global Warming and Water Resources Variability in the Maritime Region of Togo (West Africa)
Authors: Agbewornu Kwami Coco Dzidula
Published: November 2018

One of the most important climatic phenomena of our planet on the threshold of this third millennium is undoubtedly that of global warming. This phenomenon, whose impact on the global environment is disastrous, has been attracting the attention of the international community since the end of the last century. Global warming can be observed on a global scale, but with regional and local signatures. In Togo, the Maritime region which houses the bulk of industrial activities (90%) and densely populated (40% of the national population), would be more exposed to the effects of global warming than all the other regions of the country. The current study uses meteorological and hydrological data to calculate statistical indexes which show the evolution of temperatures and water resources variability. The aim is to detect the signs of global warming and the variability of water resources in order to envisage better adaptation strategies. The results of the analysis of climate data for a long enough period (30 to 50 years) demonstrated a change on rain distribution after 1960 which is prejudicial to rainfall agriculture practiced by about 90% of Togolese crop growers, and an augmentation of the average temperature about 2.2 degree celsius for Lomé and 1.7 degree celsius for Tabligbo.

Nouvelle manga, mon amour. Reflexiones sobre la narración gráfica de historias cotidianas
Authors: Hernández Ranz Olalla
Published: November 2018

Ever since its first appearance over a century ago, the comic has been gaining ground as a popular genre aimed above all at a juvenile readership. Its obvious success with readers has led some parents, teachers and reading-promotion professionals to ask themselves why it is so popular, and to draw wrong conclusions, like the belief that it has less value as reading matter: aimed basically at entertaining those who read it. Manga, in particular, is the most highly consumed comic genre in the West. It has become a profitable market product that spawns video games, TV series, films, etc. Its great appeal to children and young readers is a source of worry to mediators due to its allegedly violent and sexual overtones and the low literary quality of its works. This paper attempts to dispel certain clichés that derive from misconceptions regarding Japanese cartoons, through the study of a corpus of works by Japanese and European authors who aim to produce comics of high quality in both form and content, thus opening the door to promising new research. Nouvelle Manga is a new Japanese comic genre that brings together the most noteworthy communicative strategies of Japanese graphic novels, the aesthetic value of the French comic and the simplicity and tone of French Nouvelle Vague cinema to create a comic that tells everyday stories of great literary and aesthetic value: highly recommendable for juvenile and adult readers.

L’actuació discursiva d’un mestre novell en una classe de llengua catalana: gestió de l’aula i construcció del coneixement
Authors: Casas i  Deseures Mariona
Published: November 2018

Aquest article presenta un estudi de cas que analitza la interacció a l’aula en l’ensenyament-aprenentatge de llengua catalana a quart de primària. Concretament, l’anàlisi se centra en l'actuació discursiva oral d’un mestre novell des del punt de vista de les estratègies que utilitza per gestionar l'aula i per construir coneixement. A partir de l'instrument d'anàlisi de Castellà et al. 2007, que classifica les estratègies discursives de relació social a l’aula i les estratègies discursives de construcció de coneixement, la recerca es pregunta si l’ensenyant es comporta –durant la sessió enregistrada– com a docent efectiu des del punt de vista discursiu i quines implicacions didàctiques té la seva actuació discursiva. Els resultats demostren que el mestre usa més estratègies de gestió de l’aula que de construcció del coneixement i que el coneixement que construeix és escàs, superficial i repetitiu. Justament, les conclusions intenten respondre fins a quin punt la interacció construeix coneixement i com és el coneixement que es construeix. Partint de la base que la interacció és un mitjà per construir coneixement i no una finalitat per se, el predomini de les estratègies de gestió de l’aula al llarg de la sessió demostra que el mestre usa essencialment la interacció per anar teixint el coneixement, és a dir, que la seva habilitat en la gestió de l’aula facilita l’ensenyament-aprenentatge de coneixements nous. Amb tot, el coneixement que es construeix es caracteritza per la introducció de pocs continguts, per l’absència de reflexió metalingüística i per l’escassa presència de discurs explicatiu. L’article conclou que l’ensenyant es comporta com un mestre novell estratègic, en el sentit que la destresa gestionant l’aula atenua la seva inexpertesa construint coneixement. L’interès d’aquesta recerca rau en l’aportació d’unes reflexions sobre l’actuació discursiva d’un ensenyant novell, que poden contribuir a la millora de la formació i la pràctica docents.

Els resultats d’aquesta anàlisi mostren algunes dades que permeten reflexionar sobre la distància que s’observa entre els llibres de text analitzats i el que prescriu el marc curricular, tant pel que fa a la necessitat de partir d’una reflexió sobre el sistema lingüístic que reverteixi en una millora de les competències discursives dels estudiants, com pel que fa a un tractament integrat de les llengües.

THE INFLUENCE OF HARDNESS OF POLYURETHANE ON ITS ABRASIVE WEAR RESISTANCE
Authors: CAPANIDIS Dymitr
Published: November 2018

This paper presents the experimental determination of the effect of hardness of the polyurethane (PUR) in a form of the elastomer foam used in various parts of machines or appliances subjected to intensive abrasive wear. Such elements, among others, are static and dynamic technical seals, bumpers, shock-absorbing parts in joints of machine components, and elements of transport equipment in mining or in aggregate and mineral processing [L. 1–3]. Intensive abrasive wear also concerns parts of agricultural and construction machines, road transport, and transport packaging, as well as protective coatings, housing or shields of various machines, and equipment elements [L. 4, 5]. An increase in the abrasive wear resistance of directly determines an increase in the durability and operational reliability of machines and equipment [L. 6]. The hardness of the elastomeric polyurethane influences its physicomechanical and tribological properties [L. 7]. So far, relatively few works have focused on research into the effect of various factors, including the hardness of PUR on the tribological properties of PUR. The aim of this study is to broaden knowledge on the impact of the polyurethane hardness on its resistance to abrasive wear.
AN ATTEMPT AT IDENTIFYING THE INFLUENCE OF TEST HEAD ASSEMBLY STIFFNESS ON THE RESULTS OF A TRIBOLOGICAL EXPERIMENT CONDUCTED UNDER MICRO-OSCILLATION CONDITIONS
Authors: GAWARKIEWICZ Rafał
Published: November 2018

The outcome of experimental research on a group of dry bearing materials carried out under small oscillation conditions and using a test rig designed and made at Gdansk University of Technology inspired the decision to find out if the stiffness of test head elements influenced the generated results. Therefore, a computer model utilising finite elements was devised and used to simulate the workings of the test head. The model enabled full control of the head’s geometry, and loading and boundary conditions at every stage of simulation. Moreover, the simulation includes the preparation of test head elements, fixings, and the specimen loading, and executes the displacement of the counter-face during full-cycle reciprocating motion. Finally, the results of computer simulation are compared with those produced by experimental testing.
MECHANICAL AND TRIBOLOGICAL PROPERTIES OF OXIDE LAYERS OBTAINED ON Ti-6Al-7Nb ALLOY
Authors: ANIOŁEK Krzysztof , BARYLSKI Adrian , KUPKA Marian , DWORAK Michał
Published: November 2018

The research presented in the paper was focused on determining the effects of thermal oxidation parameters on the mechanical and tribological properties of oxide layers formed on Ti-6Al-7Nb titanium alloy for biomedical applications. Titanium alloy was oxidized at 600 and 700°C for 72h. The study found that, at lower temperatures, the oxidized alloy surface was covered by a nonuniform oxide layer. A 100°C increase in the treatment temperature yielded a uniform layer covering the whole surface of the alloy. Hardness measurements showed that thermal oxidation resulted in the formation of oxide layers characterized by a 3-fold higher hardness compared to untreated alloy. Tribological tests showed that thermal oxidation effectively improves the resistance of Ti-6Al-7Nb alloy to sliding wear. Tribological tests demonstrated that an increased oxidation temperature was associated with improved resistance to sliding wear.

Authors: GAJEK Andrzej , SZCZYPIŃSKI-SALA Wojciech
Published: November 2018

The article presents the results of the stand tribological investigation and microscopic observations of brake pad materials for automotive disc brakes. The reasons for the scatter of the friction coefficient value are analysed. The results of the brake pads’ friction surface topography observations and chemical constitution are presented. The investigations were carried out with scanning electron microscopy SEM and energy dispersive X-ray spectroscopy EDS. The point, line, and surface analysis of friction layer were done. The average contents of the chemical elements on the friction surface are presented. The heterogeneous nature of the structure on the friction layer was observed. The analysis has shown that brake pads with a compact structure of friction layer and large quantity components (10 components with more than 1% content each) had a smaller scatter of the coefficient of friction value in relation to the materials with a loose structure and less quantity components. The next part of the article presents the structure and geometric parameter products of the wear of the friction material. The problem concerning the quantity limitation of the wear particles entering the environment as dust was discussed.

Authors: KOSTENCKI Piotr , BOROWIAK Piotr
Published: November 2018

The change of temperature of subsurface layer material of ploughshare,
occurring in the course of fine sandy loam (8% moisture and temperature
15.3°C) cultivation, done with bed making plough, was determined. Measuring
system with 10 temperature sensors built in the ploughshare material was used
in the research. Temperature value was registered with frequency of 1 Hz. The
increase of temperature of subsurface layer of ploughshare blade material used
in soil was fast – time of temperature stabilization was, depending on location
the place of measuring from 17 to 43 s. In the course of ploughing the most heated was the initial area of the attack of landslide part of ploughshare blade
and area adjacent to field edge – from 42.6 to 47.3°C. The temperature of
material of trapezoid part of ploughshare blade was 26.6 to 29.7°C. In the
conditions of the conducted measurements the rate of cooling of the subsurface
layer of ploughshare blade material as the result of its cooling was 0.007 to
0.028°C·s-1 while plough was not working, however while making U-turns was
from 3 to 7 times higher. In the places where the material of ploughshare blade
was more heated the rate of cooling was of course higher. Faster cooling of
ploughshare blade during U-turns was probably the result of intensified cooling
induced by plough movement in the air.
A GENERALIZED METHOD FOR PREDICTING CONTACT STRENGTH, WEAR, AND THE LIFE OF INVOLUTE CONICAL SPUR AND HELICAL GEARS: PART 2. HELICAL GEARS
Authors: CHERNETS Myron
Published: November 2018

The paper presents the results of research undertaken to determine maximum contact pressures, wear, and the life of involute conical helical gear, taking account of gear height correction, tooth engagement, and weargenerated changes in the curvature of their involute profile. We have established the following: (a) initial maximal contact pressures will be almost the same at the engagement in external and internal segments; (b) their highest meanings occur in different points of engagement depending on the coefficients of displacement; (c) the maximal tooth wear of the rings in the internal section will be a little bit lower than in the external; (d) the coefficients of displacement have an optimum at which the highest gear life is possible; and, (e) the gear life in the frontal section will be 1.25 lower than in the internal section. The calculations were made for a reduced cylindrical gear using a method developed by the authors. The effect of applied conditions of tooth engagement in the frontal and internal sections of a cylindrical gear ring is shown graphically. In addition, optimal correction coefficients ensuring the longest possible gear life are determined.

METHODOLOGICAL ASPECTS OF DETERMINING
THE COEFFICIENT OF KINETIC FRICTION OF WHEAT KERNELS
ON AN INCLINED PLANE
Authors: KONOPKA Stanisław , KOLANKOWSKA Ewelina
Published: November 2018

One of the most popular methods of determining the coefficient of kinetic friction between a pair of solid
objects involves an inclined plane. However, manual measurements of the time taken by a particle to travel
a certain distance (usually performed with a stopwatch) and the angle of an inclined plane (on a scale) are not
always highly accurate or precise. The coefficient of kinetic friction has to be determined on the assumption
that a particle moves in uniformly accelerated motion. The aim of this study was to analyse particles moving
in uniformly accelerated motion on an inclined plane and to modify the method of measuring movement
parameters. A mechatronic measuring device and a high-speed camera were used to monitor the movement
of wheat kernels on a steel friction plate. The experimental variables were the distance between photosensors
(length of the measured section) and the kernel’s position relative to the direction of movement. An analysis
of the mean values of time taken by particles to travel different distances revealed that the particles were
not moving in uniformly accelerated motion. The results indicate that the coefficient of kinetic friction of
irregularly shaped particles cannot be determined reliably on an inclined plane. Several recommendations for
modifying the test stand were proposed.
TRIBOLOGICAL PROPERTIES OF BLACKBERRY WASTE SEED EXTRACT OBTAINED UNDER SUPERCRITICAL CO2 CONDITIONS WITH SORBITAN ESTERS COMPOSITONS
Authors: MAŁYSA Anna
Published: November 2018

This paper presents results of tribological research of a composition containing as a base, extract of waste blackberry seeds obtained by extraction under supercritical carbon dioxide conditions with sorbitan esters as additives (sorbitan trioleate (STO) sorbitan monolaurate (MLS) and etoxylated sorbitan monolaurate (EO20MLS)). The influence of the concentration of surfactants on the motion resistance, wear and anti-seize properties of the obtained lubricants was analysed. Two types of tests were performed: seizure, with linear load increase and constant load (four-ball device T02). The obtained test results compared to the results for the base (pure extract) to paraffin oil and rapeseed oil were related. It was found that the addition of sorbitan esters to the extract has a greater effect on the improvement of anti-seizure properties than on the reduction of resistance to movement and wear to the base.
IMPACT OF ADHESION AND VISCOSITY FORCES ON FRICTION VARIATIONS IN BIO-TRIBOLOGICAL SYSTEMS
Authors: WIERZCHOLSKI Krzysztof , MISZCZAK Andrzej
Published: November 2018

The classical theory of lubrication holds that the lubricant dynamic viscosity increments cause the increments of hydrodynamic pressure, as well as friction forces and wear. In the case of high values of hydrodynamic pressure, it very often has a significant impact on the friction coefficient. New achievements in the field of micro-and nano-tribology provide for new hypotheses on the decrements and increments of the friction coefficient in the case of the lubricant viscosity increments. Experimental investigations have shown that, even in the case of decrements of the friction coefficient with the lubricant viscosity increments, such decrements are very often lower than simultaneous hydrodynamic pressure increments which results in the friction force increments with the lubricant viscosity increments. In biological friction nods, we can observe a varied impact of the biological lubricant viscosity on the friction force and friction coefficient values. The abovementioned impact is caused by the adhesion and cohesion forces occurring between the biological fluid particles flowing around the phospholipid bilayer on the superficial layer of the cartilage with varied wettability and hydrogen ion concentration. The wettability (We) and power hydrogen ion concentration (pH) have a significant impact on the physiological fluid or biological lubricant viscosity variations and, as a result, on the friction forces and friction coefficient. This paper describes the abovementioned impact and the process of friction forces and friction coefficients variations in biological friction nods.
EFFECT OF HOLE-FORMING TECHNOLOGY ON THE DESTRUCTION OF MATERIAL DD11 USED TO MANUFACTURE WHEEL DISCS
Authors: RYCHLIK Arkadiusz , LIGIER Krzysztof , KOZUBEL Władysław
Published: November 2018

This study presents the results of comparative tests concerning the destruction process of specimens made of material DD11, for which different hole-forming technologies (i.e. drilling and piercing) were applied. For the analysis of cross-sectional properties of a specimen in the process of destruction, relative vibrations of the specimen’s free end as a function of vibrations of a forcing mechanism (vibration inductor) were selected as the diagnostic signal. The tests were carried out on a test stand on which the destruction process of the material’s cross-section was induced by the specimen’s inertial force. Based on the conducted testing, it was found that the average value of cycles to damage a specimen with holes made using the drilling technique were more durable than the specimens with holes made using the piercing method.

In the face of World War II, Latvia lost its centuries-old multiculturalism, as well as progressive climate and tolerant society. The losses of the indigenous Baltic population reached almost 30%, therefore, with the effects of these events, the Republic of Latvia is struggling to this day using a multi-layered national policy. The characteristics of new actions, the participation of national minorities in the structures of society and the assessment of the effectiveness of implemented modifications are the subject of this study.
INFLUENCE OF SURFACE LASER TEXTURING ON FRICTION AND WEAR OF PTFE DURING SLIDING AGAINST STEEL
Authors: KOWALEWSKI Piotr , GAŁEK Tomasz
Published: December 2018

The paper presents research and analysis of PTFE wear during cooperation with steel. The surface of steel elements was subjected to laser texture. Three different patterns of texture were applied to the surface of steel elements. For comparative purposes, an element without a structure was also tested. The experiment was carried out in a roller-plate test on the author’s research stand. As part of the conducted tests, the linear wear of PTFE plates was determined, and the values of the kinetic and static friction coefficients of the tested friction pairs were determined. Steel friction surfaces were also subjected to SEM microscopic observation. The obtained results showed an apparent effect of laser texture on changes in friction and wear of PTFE. This influence is different and depends on the pattern of the texture.

AN ANALYSIS OF THE IMPACT OF THE FDM TECHNOLOGY PARAMETERS ON TRIBOLOGICAL PROPERTIES
Authors: KOZIOR Tomasz , KUNDERA Czesław
Published: December 2018

The paper presents the results of tribological tests for sample models made by FDM technology. The ringshaped samples were made of the ABS P430 material using the Dimension 1200es machine. Disc-shaped counter-samples were made of C45 steel. The analysed technological parameter of the process of building sample models was the “printing” direction (between the friction surface of the sample and the building platform), determined at three degrees of variability (0°, 45°, and 90°). Using the T-15 tribological tester of the ring-on- disc type, a study was carried out to determine the effect of printing direction on the friction force and the total friction wear. In addition, metrological measurements of the tested surfaces were carried out.
EXPERIMENTAL STUDIES ON THE INFLUENCE OF ABRASIVE MATERIALS ON THE WEAR OF HARD-WEARING STEELS
Authors: WIECZOREK Andrzej N.
Published: December 2018

The paper presents the wear properties of hard-wearing steels and structural steels used in mining and transport machines exposed to the aggressive action of the environment, which have been determined experimentally in the presence of diverse abrasive materials. The wear tests were carried out on a ring-on-ring test rig simulating the operating conditions of elements exposed to abrasive wear. The samples were subjected to tests in conditions of sliding contact, and the main destructive process was micro-cutting of the surface with loose corundum or quartz grain. In the case of the coal abrasive, only slight grinding in of the mating surfaces was observed. The loss of mass in the samples was measured as the parameter characterizing the wear. It was then used to determine the volume loss. Based on the results obtained, it was found that the wear resistance of hard-wearing steels was approximately four times higher as compared to S355J2 structural steel for the corundum and quartz abrasives. In the case of the coal abrasive, there was a relatively low wear for all of the materials examined.

Placental Cytomegalovirus Infection
Authors: Lindholm Kaleigh , O'Keefe Mary
Published: November 2018

In the United States, cytomegalovirus is the most common congenital viral infection and the number 1 cause of nonhereditary sensorineural hearing loss. The vast majority of infants may be asymptomatic, especially if cytomegalovirus is contracted later in the pregnancy, and some symptoms may have a delayed onset. Therefore, it is important for the pathologist to identify the common histologic findings to help confirm the diagnosis so the child can be followed for late sequelae. Histologic examination of the placenta is important in live births and in cases of intrauterine fetal demise. Chronic lymphoplasmacytic villitis and fibrotic, avascular villi are the most common findings. When present, Cowdry A intranuclear and basophilic intracytoplasmic inclusions are characteristic. Immunohistochemistry for cytomegalovirus can highlight these inclusions as well as the associated eosinophilic debris. In addition, polymerase chain reaction or viral culture on placental or fetal samples can be performed for confirmation.
Improving temporal consistency of preferences: The influence of mental construal
Authors: Aydin Asli Elif
Published: November 2018

Majority of the current literature on mental construal has focused on effects of varying construal levels on preference shifts whereas this research investigates the influence of mental construal on the change of preference consistency over time. Building on construal level theory, we propose that high-level construal, which creates abstract, and decontextualized mental representations, leads individuals to more consistent preferences than low-level construal, which creates concrete, and contextualized mental representations. Furthermore we examine the effect of having a matching versus non-matching construal level at two different evaluation instances, on achieving greater extents of consistency. To test this prediction a mixed experimental design is employed, in which participants evaluated electronic products at two different sessions. It is demonstrated that when participants have the same construal level at two points in time, their evaluations become similar since they mentally construe the objects in the same way whereas when the construal level differs at these two points, participants focus on different aspects of the products, form different evaluations and have less consistent preferences.
Investigating the effects of cultural-mindset priming on evaluation of job performance behaviors
Authors: Mishra Vipanchi , Bost Marcus
Published: November 2018

Recent reviews of performance evaluation process and practices indicate that there is substantial variability in the structure and formalization of performance evaluations in organizations across cultures and call for further exploration of the role of cultural variables on the performance evaluation process. In the current study, we use self-construal priming procedures to evaluate the effects of cultural mindset on the performance evaluation process. Specifically, the effects of independent (individualistic) and interdependent (collectivistic) mindset priming on relative importance given to performance behaviors when making judgments of overall job performance was investigated. Participants first completed either independent (n = 87) or interdependent (n = 87) priming tasks by circling either I/me/my or we/us/our in a paragraph of text. Following this, they completed a managerial role-play exercise in which they read employee performance vignettes (manipulated on task, citizenship and counterproductive performance behaviors) and rated the overall performance of each employee. Rater policies were captured using regression analyses and relative weights placed on each performance behavior were computed. Results suggest that when making judgments of overall performance, as compared to raters primed with interdependence, raters primed with independence placed less weight on citizenship behaviors and higher weights on counterproductive performance behaviors. No significant differences were observed in the weights placed on task performance behaviors. Study limitations and implications for research are discussed.
Formação de um grupo teatral na escola: Dificuldades e possíveis soluções para a introdução da linguagem teatral em alunos de uma instituição em um horário extraclasse
Authors: Pontes Joana Barreto
Published: November 2018

Este artigo pretende discutir a realidade de uma escola localizada numa região central de Florianópolis no estado deSanta Catarina, onde os alunos por uma questão geográfica teoricamente teriam acesso às atividades culturais e teatrais,no entanto, na prática o professor de artes que inicia um trabalho teatral com uma turma, tem sempre que partir doinício. Não existe uma continuidade no que é trabalhado com determinada turma em sala. Isto acaba por se agravar a partir do momento em que a disciplina Teatro, não está categorizada neste momento como uma disciplina obrigatória dentro da grade escolar.

Considerações sobre a Cultura Visual e sua influência no imaginário adolescente: um Estudo a partir da Construção Plástica e do Conceito de Apropriação
Authors: Perez Karine Gomes
Published: November 2018

O presente artigo, o qual relata uma experiência de ensino vivenciada em meio não formal na cidade de Santa Maria, Rio Grande do Sul, originou-se a partir de Monografia apresentada pela autora em setembro de 2006, no Curso de Graduação em Desenho e Plástica - Licenciatura Plena, da UFSM. Seu principal objetivo foi constatar a influência da cultura visual no imaginário adolescente, através da construção plástica, partindo do conceito de apropriação. Para esse fim, houve o contato direto e constante com um grupo de três adolescentes, visando-se à obtenção de dados para a presente pesquisa. Nesse sentido, foi trabalhada a arte contemporânea, mais especificamente, o conceito de apropriação, devido a sua amplitude, que permitiu ao grupo construir plasticamente, usando materiais diversos pertencentes à cultura visual. Assim, através dos trabalhos produzidos e de uma entrevista semi-estruturada, foi possível estabelecer relações entre a cultura visual, o imaginário adolescente e o Ensino das Artes Visuais.
O Exercício do Olhar Numa Propaganda de Tv: Explorando o Sincretismo da “Fazendinha Tirol”

Published: November 2018

Considerando o acúmulo de imagens visuais que inunda o cotidiano atual e a significativa inserção que a televisão possui em diferentes contextos sociais, percebemos a necessidade de promover uma leitura crítica acerca do repertório imagético disponibilizado através das propagandas veiculadas na TV. A fluidificação das fronteiras entre Arte e cotidiano também é fator que convoca os educadores de Arte para investigar sobre os sentidos que são abstraídos pelossujeitos ao visualizarem um audiovisual. Neste artigo exploramos os sentidos contidos na propaganda de TV intitulada “Fazendinha Tirol”, veiculada em 1999, utilizando como marco teórico a semiótica discursiva, a qual tem sua ênfase principal no processo de construção da significação. O sentido de um texto é dado pela rede de inter-relações que o leitor faz entre os elementos que constituem o texto, seus procedimentos relacionais e repertório cultural pessoal.
Uma reflexão Sobre Etnomusicologia e Educação Musical: Diálogos Possíveis
Authors: Pereira André Luiz Mendes
Published: November 2018

Proponho uma reflexão crítica que considere os conhecimentos relacionados à cultura popular, e, em especial, aqueles ligados ao universo da música afro-brasileira, seus modos de funcionamento, seus sentidos, a maneira como seus saberes musicais são transmitidos e em possíveis aplicações deste saber em sala de aula. Para a realização deste artigo, darei enfoque às transmissões musicais presentes na manifestação do congado, sobre a qual realizei minha dissertação, e na maneira como diferentes aspectos podem auxiliar o professor na sua prática de educador. Dessa forma, refletindo e analisando as práticas de ensino/aprendizado em música e a formação de professores, assim como em metodologias e didáticas, busco compreender as experiências musicais de contextos culturais específicos na elaboração de possíveis práticas pedagógicas.

Authors:   Universidade Federal de Uberlândia, Paula Wellington Menegaz de
Published: November 2018

Nesse artigo analiso o processo de criação de Sol Ardente e Depois Daquela Viagem. Trata-se de uma prática de ensino do teatro, baseada em processo colaborativo, desenvolvida em 2007, com vinte e sete adolescentes, dentro do Projeto de Teatro, atividade extracurricular, da Escola Municipal Dr. Gladsen Guerra de Resende, localizada no bairro Jardim Canaã, de Uberlândia (MG). Durante o ano de 2007, procurei, enquanto professor do Projeto de Teatro, dialogar com os alunos, para saber o que queriam falar, quais os temas que julgavam importantes de serem debatidos e improvisados em aula. Era uma prática teatral feita por adolescentes e que dialogava com a realidade do bairro Canaã. Cabe destacar que esse estudo faz parte da minha dissertação de mestrado intitulada O Teatro e os Adolescentes do Canaã: Aspectos Artísticos e Comunitários, desenvolvida no Programa de Pós-Graduação em Teatro da Universidade do Estado de Santa Catarina.
