A ideologia dos filmes utilizados na educação infantil: uma análise a partir da teoria crítica

This work has as purpose to show what are the influences of media in the education and in the shaping the thinking and understand that ideologies are present in the films used in the classroom in kindergarten. For this, I directed the discussion beginning by concepts as Ideology and its more different definitions by several thinkers over the years, the thinkers of Critical Theory of Frankfurt School, called “frankfurtians” of first and second generation of this school, also making an association between Cinema and Education, evidencing concepts involving this association as Cultural Industry, using films properly in classrooms in kindergarten, with the teacher as mediator and then discussed what amounts of movies on children's education, how they assist and deepen the knowledge developed by students in schools of infantile education. Additionally, they are exposed the different opinions about the subject Film and Education for students from kindergarten, what benefits and what disadvantages in the use of films, the different opinions on the subject. We also discuss, in this work, the ideologies present in three films produced by Walt Disney, they are Cinderella, Snow White and the Seven Dwarfs and Alice in Wonderland, relating them to how they can contribute to the development and learning students in kindergarten. I associated more as possible the previous discussions to analyze the ideologies present in these films, by summarizing these, and decomposing them through an analysis tool called frame. Finally, I completed everything that was discussed and analyzed, which students in kindergarten may develop with the use of films in schools, what they contribute, in some way, for the learning and education of students as viewers using the school as access to different cultures and the teacher as a mediator of this relationship

Análise da deposição de filmes finos semicondutores de GaN e GaN e Ga1-xMnxN preparados por sputtering reativo

Thin films of Ga1-xMnxN have great interest in its potential for control of electron spin (spintronics), in most cases this material is synthesized by techniques that have a high degree of control the deposition parameters, such as molecular beam epitaxy (MBE) and deposition of metalorganic chemical vapor deposition (MOCVD). The sputtering technique is an alternative route to produce such materials. Here we study the film deposition Ga1-xMnxN by reactive sputtering technique and apply enhancements such as a glove box, a residual gas analyzer and temperature control system, in order to growth films epitaxially using an analysis of the preconditions of films analyzed by spectroscopic techniques and microscopic. These procedures helped to improve the technique of deposition by cleaning substrates in an inert environment, and by the analysis of trace gases and heating the substrate holder as explained in the literature. Through the applications and comparisons it can be pointed out that the technique has the advantage of its simplicity and relatively low cost compared to MBE and MOCVD, but produces polycrystalline material

A violência escolar retratada pelas lentes do cinema

This work of completion is inserted at the interface between violence and school, and how you want to portray violence in school is represented in film productions. We consider important to first discuss in depth the concepts of violence to better understand the phenomenon of school violence, which is a subject much discussed in recent times. One of the types of violence very often nowadays, taking forms that we can call as new, in primary education schools, as well as in society in general, is known as bullying, for some authors the concept is very close to the definition of prejudice in with respect to social factors that reflect the target groups of this type of violence. Other authors also research on the expansion of the recent phenomenon known as School Shooting, which means school shootings, very common in American schools. Our study builds on ideas Debarbieux and Blaya (2002) that treat violence more broadly, taking into account the reports of the victims, including symbolic violence, the institutional and physical. For them, every concept must take into consideration how it was socially constructed, to thereafter be searched. Our goal is to analyze and understand how the issue of school violence is treated theoretically and also as is portrayed through the lens of cinema. Our study is theoretically based on authors like Debarbieux, Blaya, Bourdieu, Charlot, Arendt, Foucault, Sposito, among others, and use the qualitative approach, working with content analysis of films

Estudo comparativo do desempenho de diferentes membranas oclusivas de Látex Natural no reparo ósseo

Introduction: In dentistry, alveolar bone resorption is a limiting factor in the well being of individuals directly interfering in the stomatognathic system, causing problems in the context of overall health. Aiming to promote biological methods that can stimulate bone regeneration, several biomimetic strategies have been developed by the use of diverse materials possible to the bone matrix, culminating in the development of techniques that promote such repair. Objective: This work is a comparative study of the performance of films made with latex as occlusive membrane for Guided Bone Regeneration (GBR) procedure in three preparations: Latex preserved in ammonia, produced by Latex rubber clones IAN873 and PR255 polymerized immediately after collection and without use ammonia as a preservative. Methods: Sixty Wistar rats were randomly divided into 4 groups of 15 animals in which bone defects of critical size (8mm diameter) were made surgically in the skull. Group A was treated by GBR through the membrane latex preserved with ammonia, Group B received the membrane made of latex from IAN873, Group C, the membrane clone PR255 and group D was not treated by GBR. After a period of 7, 15 and 50 days, 5 animals from each group were euthanized, and specimens containing bone defect collected for microscopic examination (descriptive histology and histomorphometry). Results: The results showed that after 50 days there was bone formation in higher proportions in group D (p <0.05, ANOVA followed by Tukey), suggesting that further experiments should be conducted to conclude about the presence of ammonia and the influence of kind of rubber. Conclusion: GOR is a procedure proven effective in the treatment of bone defects. Therefore, further experiments should be conducted to reach a conclusion regarding the presence of ammonia in the latex composition for the manufacture of membranes, as well as the difference induced by the species of rubber.

A arte nas ondas do rádio: ações e procedimentos para esta prática

This paper proposes an extension of the personal experience of the listener through radio. The radio, because it is a medium of reaching, disseminating and having considerable accessibilities towards the production of its contents, and if exploited, could very well combine functionality with aesthetics in the production and broadcasting of programs, something that makes the radio not only a means for transmission of information. In the production of dramatic art, for example, the use of other elements, such as sound effects, may suggest form and consistency to the object described during the practice of radio utterance. The proper combination of function and aesthetic in music, sound effects and voiceover radio can change the mood of the listener and even promote their creativity.

Interfaces de notícias táteis em conteúdos gamificados contemporâneos

The construction methods of information lean on in variable models in the contemporary, especially by the diversity of languages and platforms offered. Among the innovations we find a growth of the gamification effect in the representation or reinforcement of the news, seizing the moment entertainment to increase user engagement. This research presents, from a case study published by The New York Times on the information complement referring to the World Cup Brazil 2014, studies of the importance of the interface in the broadcasting of informative contents, especially in a society where the tactile sensation is growing.
