"Ombro a ombro com os mais fracos": a inserção de João Café Filho nos espaços do trabalhador na cidade do Natal 1922 - 1937

The purpose of this thesis is to analyze how João Café Filho constituted a discourse of advocate of the labor movement and workers in different sociability spaces. It is intended to understand, on one hand, how political relations were established between different categories of workers and the ‘middle classes’ and, on the other hand, how places were instituted to house the meeting of these relations. It a ims to understand the insertion of Café Filho in union activities in the urban world. It demonstrates specificities of the political culture in Natal emphasizing the dispute between a city politically ruled by a still reigning rural paternalistic mentality and the rise of a new way to experience the urban conflicts which appeared. Temporally, the work is delimited between 1922 (proclaimed by Café Filho himself as the initial period of his political action) and 1937 (when he broke up with Vargas and went into exile in Argentina). The research was constituted by three main document types: several published newspapers between the decades of 1920 and 1930 in the cities of Natal, Recife, São Paulo, Porto Alegre and Rio de Janeiro; the autobiographical memoirs written by Café Filho himself and memoirs of other people who lived in his time. The main pillars that have supported the work were: the concepts of society and individuals (ELIAS, 1994; 1995), political cultures (BERSTEIN, 1998) and theater of the memory (GOMES, 2004); the sociability spaces category (CERTEAU, 1994; MALATIAN, 2001; RIOX, 1996); the biography notion (DOSSE, 2009; LORIGA, 2011). We demonstrated that Café Filho acted in some sociability spaces as: the Jornal do Norte, the Federação Regional do Trabalho and the Partido Democrático Nacional. In such spaces, Café Filho, gradually, become an important leader of workers and, at the same time, linked to national entities led to the opposition that fight against the power established in the Brazilian First Republic. In Café Filho’s interpretation, workers were individuals who needed to fight against the political structures prevailing at that time because the poor living conditions and the low representativeness of this group were caused by the way the political system in the First Republic was structured. After the 1930 Movement, the 3 de Outubro Club, the Jornal and the Labor Federation of Natal were constituted in spaces where the cafeista critical discourse about the government was changed: workers should follow the official syndicalism and defend the 1930 Movement which put Vargas in the presidency of the Republic.

Avaliação das condições higiênico-sanitárias da produção de refeições à base de carne da alimentação escolar no município de Natal-RN

The National School Nutrition Program is the oldest program in the country directed at food and nutrition safety. Its aims are to offer nutritional food as a supplement to students of public and philanthropic schools. Studying school nutrition transcends the investigation as a purely social program, given that it reaches the fields of public health, nutrition and food, using a wide variety of approaches. Thus, it is characterized by a multidisciplinary study, where the disciplines work side by side in distinct aspects of a single problem. Aim: This study aims to assess hygiene practices during the preparation of meat-based meals in public schools in the city of Natal, Brazil. Methods: A list was applied at 27 schools to identify the procedures of good food preparation practices. In addition, cooking and meal distribution temperature were measured and a microbiological analysis of the final preparation and of the water used in preparing it was performed. For microbiological analyses of the food, we analyzed coliforms at 45°C, coliforms at 35°C and Enterococcus, and for the water, we analyzed thermotolerant coliforms and total coliforms, using the methods recommended by APHA, 1995. Results: Most of the schools did not meet the required standards in all the variables related to good food preparation practices, except for the time spent preparing the meat, in which 89% were within the norm. Cooking temperature of the meals was within the standard; however, the temperature at distribution and the time spent dispensing the meals were inadequate. Of the 27 schools, 22 (81.5%) showed the presence of coliforms at 35° C in at least one meal sample and 18 (66.7%) had values above the recommended limit for coliforms at 45°C. The presence of E. coli was identified in 6.1% of the samples analyzed. The presence of Enterococcus was not found at any of the schools. With respect to the water, the North district of the city was the only one that did not meet the standards for the two indicators evaluated. The contamination found was not associated with the hygiene or food storage problems observed. Conclusions: The results show that the hygiene-sanitary conditions of meat-based public school meals were unsatisfactory, demonstrating the need for improvements in the production process to preserve the health of the student population. Multidisciplinarity: Researchers from the areas of food microbiology, nutrition, public health and statistics took part in this study, a decisive factor for characterizing the research as multidisciplinary

Resistotipagem e transferência genética de plasmídios de resistência entre coliformes e vibrios potencialmente patogênicos para o homem isolados de camarão (litopenaeus vannamei) comercializado em Natal-Rio Grande do Norte

Cinquenta amostras de camarão fresco e refrigerado (Litopenaeus vannamei) foram coletadas em diferentes pontos de comercialização na cidade de Natal RN. As amostras foram maceradas em um gral estéril e 25 gramas semeadas em 225mL de APA contendo 1% de NaCl e 25g em 225mL de CL incubadas a 35ºC - 24 horas. O crescimento em APA foi semeado em placas de Ágar TCBS, incubadas a 35ºC-24h para isolamento de Vibrio e Aeromonas. O crescimento do CL foi semeado em Agar EAM, para isolamento de coliformes. Dos 102 isolados, 91 (89,2%) pertenciam ao gênero Vibrio e 11 (10,8%) ao gênero Aeromonas, com predominância de V. cholerae não O1/não O139, V. alginolyticus, V. carchariae e V. parahaemolyticus K- e A. veronii biogrupo sobria , A. jandaei, A. schubertii, A. veronii biogrupo veronii e A. hydrophila. A menor eficiência entre os antimicrobianos foi da AMP (57,8% de resistência) seguida da AMK (29,4%) e TCY (21,6%). As 39 cepas de Vibrio e Aeromonas multirresistentes se distribuíram em 10 perfis distintos, sendo que um revelou cinco marcos (AMP, CHL, NIT, SXT e TCY) em um isolado de V. carchariae de camarão, adquirido em supermercados. O índice MAR, nas 39 cepas variou de 0,28 a 0,42, sugerindo que são de risco na transferência e difusão da resistência na cadeia alimentar. Após a cura plasmidial pelo tratamento com AO de 24 cepas multirresistentes e com resistência intermediária de víbrio e aeromonas escolhidas aleatoriamente, 13 perderam totalmente a resistência e 7 perderam parcialmente, sendo que o maior percentual de perda da resistência ocorreu nas cepas de V. cholerae não O1 e não O139 (6 cepas), se concentrando nos marcos de resistência a AMP (13), AMK (11), TCY(8) e CIP(3). Os resultados da conjugação realizada entre amostras de Vibrio xvi curadas e a E. coli K12C600 demonstraram que 78,5% das culturas de Vibrio testadas revelaram capacidade de transferência para o gene que confere resistência a AMP e 28,5% para a TCY. Dos coliformes, E. coli foi a mais frequente, seguida de Citrobacter spp, isoladas em 40,3% e 27,5% das amostras respectivamente. AMP foi o antimicrobiano menos eficaz, seguido de TCY. As 11 cepas multirresistentes se distribuíram em 9 perfis distintos, um deles constituído de cinco marcos (AMP, NIT, TCY, CHL, SXT), albergados em uma cepa de Klebsiella spp, oriunda de camarão adquirido em supermercado, similar ao resultado obtido em V. carchariae. Conclui-se que, os camarões marinhos frescos e refrigerados, comercializados em Natal-RN evidenciaram contaminação com coliformes, víbrios e aeromonas multirresistentes a antimicrobianos comumente utilizados na terapia médica e veterinária, e que, possivelmente, a transferência de genes de resistência entre bactérias se constitui um sério problema de saúde pública

O ensino da história e o pensamento reflexivo-crítico da professora no 3º ano do Ensino Fundamental

This collaborative research is a qualitative approach, from historical and cultural perspective, made about a teacher of third grade of basic education in the area of history, in the municipality of Caicó / RN. It has as objective to investigate, in a collaborative action, if the design process of teaching and learning the discipline of history based on the relationship before / after allows the development of critical reflective thinking of the teacher in school practices. The theoretical and methodological approaches are supported in the postulates of Vygotsky (1998), Rubinstein (1973) and Linblinskaia (1979), among others, whose understanding has led us to reflect if the teacher develops the reflective critical-thinking in history discipline classes. The complexity of the study led us to an analysis exercise, using different methodological procedures, such as: bibliographic review of the literature, considering also the literature of the history area, interviews, observation in the classroom, video recordings and reflective sessions, enabling clarify the construction and reconstruction of thought that the teacher had been developing during the process of teaching and learning. The test results point to a dichotomy between theory and practice, and also to a certain fragility in the position of professor in teaching and learning the discipline of history, at the third grade of basic education. The teacher recognizes that she requires a theoretical deepening with more intensity, as a process of continuous training to improve the practice of teaching in history school, though, stating in her speech that her teaching practice is based on critical reflection. However, she presents serious limitations in classroom practices. We conclude that, although she has shown willing to work on a critical perspective of reality, showed also poor change at school practices, starting to reflect about her own actions, pointing her limits and the changes needed that didn t become reality yet. It s necessary a formative process for her. The study therefore showed that even with the sessions and reflective of deepening theoretical studies, the teacher does not change its profile, while maintaining its traditional vision in any pedagogical action. This research recommends the formation of school groups for further studies and discussion on the practices of education in history area from a reflective-critical thought perspective as a mean of personal and professional development

Uma conversa na escola: o diálogo e a mídia

The dialogue represents an essential condition for the complete realization of the Communication. In Paulo Freire we find a concept of dialogue which expresses itself, fundamentally, in two dimension: on one hand, in the confluence of subjectivities; on the other, in action. Dialogue would not be, therefore, a thinking for , but a thinking with . On the other hand, the media, here understood as synonym of technical media of information and expression is spread all over society as synonym of communication media. In this direction, this paper intends to check if the media allows the dialogue, in the heart of the Freirean concept of communication. We start from the premise that it is not possible to come to an answer if we continue to accept the theoretical approach which polarizes the process of communication between emitter and receptor. By using elements of the ethnomethodology such as the analysis of the conversation and the reflexivity, we dived in the school everyday life of educators and students of an elementary level public school in the city of Natal, capital of Rio Grande do Norte, in order to, through some experiences with the media, corroborate Paulo Freire's ideas, stating the mediation made by the world and seeking a bias for the use of the media to enable a more dialogic education

Conhecimento dos adolescentes sobre métodos contraceptivos: pesquisa-ação em uma unidade do programa saúde da família de Natal

It is a descriptive study with a qualitative approach, and an action-research type, which aimed to analyze the changes of knowledge about contraceptive methods invested to a teenager group attended in Igapó Family Healthcare Unit, in the city of Natal/RN, after consent and institutional assent of Ethics Committee of Rio Grande do Norte Federal University (Protocol No. 131/07). It were researched 16 teenagers of both sexes, with age ranging from 11 to 16 years. We used two structured questionnaires, one in the initial diagnosis and another during the seven meetings of the focus group, in addition to the field notes and the meetings discussions transcriptions. The data-collection was performed in the period of two months by a team composed by a nurse the research coordinator, a dentist, a nursing assistant, a community-based healthcare worker and a nursing academic. The quantitative and qualitative data were organized, tagged and categorized into spreadsheet in Microsoft Excel, being held a thematic analysis of speeches performed by the study participants. The results were presented as tables, graphics, photos, drawings and word clippings. The educational strategy developed in focus group allowed adolescents to discuss, exchange ideas and opinions on several contraceptive methods, providing expansion in knowledge of all contraceptives discussed, especially those natural and surgical, which were less mentioned at the beginning of the study. Among the advantages of the contraceptive methods listed by teenagers, was highlighted avoiding pregnancy and STDs in use of the barrier method of condom. As for the disadvantages more frequently noted by the survey with the misuse of barrier methods, was highlighted get pregnant, acquire STD's and do not prevent STD's in hormonal, natural and surgical methods. Adolescents showed consistency between the advantages and disadvantages and types of contraceptive methods, showing a widening in knowledge among them. It may be said that, in general, those surveyed had a good understanding about the use of the various contraceptive methods. Thus, the study participants had positively evaluated all the criteria used to qualify the meetings in the focus group. The action strategy of the focus group should be encouraged by professionals who work with teenagers, since they prefer to live in groups, one characteristic of adolescence.

Uma Fundamentação Intervalar Aplicada à Morfologia Matemática

This work present a interval approach to deal with images with that contain uncertainties, as well, as treating these uncertainties through morphologic operations. Had been presented two intervals models. For the first, is introduced an algebraic space with three values, that was constructed based in the tri-valorada logic of Lukasiewiecz. With this algebraic structure, the theory of the interval binary images, that extends the classic binary model with the inclusion of the uncertainty information, was introduced. The same one can be applied to represent certain binary images with uncertainty in pixels, that it was originated, for example, during the process of the acquisition of the image. The lattice structure of these images, allow the definition of the morphologic operators, where the uncertainties are treated locally. The second model, extend the classic model to the images in gray levels, where the functions that represent these images are mapping in a finite set of interval values. The algebraic structure belong the complete lattices class, what also it allow the definition of the elementary operators of the mathematical morphology, dilation and erosion for this images. Thus, it is established a interval theory applied to the mathematical morphology to deal with problems of uncertainties in images

Especificação de uma rede MPLS fim-a-fim com diferenciação de serviços

New multimedia applications that use the Internet as a communication media are pressing for the development of new technologies, such as: MPLS (Multiprotocol Label Switching) and DiffServ. These technologies introduce new and powerful features to the Internet backbone, as the provision of QoS (Quality of Service) capabilities. However, to obtain a true end-to-end QoS, it is not enough to implement such technologies in the network core, it becomes indispensable to extend such improvements to the access networks, what is the aim of the several works presently under development. To contribute to this process, this Thesis presents the RSVP-SVC (Resource Reservation Protocol Switched Virtual Connection) that consists in an extension of RSVP-TE. The RSVP-SVC is presented herein as a mean to support a true end-to-end QoS, through the extension of MPLS scope. Thus, it is specified a Switched Virtual Connection (SVC) service to be used in the context of a MPLS User-to-Network Interface (MPLS UNI), that is able to efficiently establish and activate Label Switched Paths (LSP), starting from the access routers that satisfy the QoS requirements demanded by the applications. The RSVP-SVC was specified in Estelle, a Formal Description Technique (FDT) standardized by ISO. The edition, compilation, verification and simulation of RSVP-SVC were made by the EDT (Estelle Development Toolset) software. The benefits and most important issues to be considered when using the proposed protocol are also included

A manifestação da vontade da criança na disputa judicial da guarda: escuta psicanalítica/

Currently, in custody disputes, the child has the right to be heard and to have its opinion considered, according to its age and maturity. The psychologist/psychoanalyst who works in the Family Court is required to produce a Report with the purpose of helping the Court´s decision. The present research aims to discuss and to find guiding principles for the hearing of the declaration of the child´s will in a custody dispute by its parents, from a psychoanalytical perspective. The case of a nine year old girl that affirmed in Court the desire of living with the mother and seeing the father only once a year is the starting point of this theoretical research over the psychoanalytic fundaments of the hearing of the case, how it appeared in that experience and how it was reflected in the report. Throughout this work, the peculiarities of psychoanalysis as a way of understanding the subject and the conditions that must be observed so that a sctrictu sensu analytic hearing is possible are studied. Then we present a reflection of the case, in the light of the theories studied, verifying that we could observe in the experience: i) the assumption of a subject of the unconscious, divided and desire full that constitutes itself from the oedipic structuration, that leads to the difference between speech and speak; ii) the concept of the child as having a sexuality of its own; iii) a hearing based on the ethic principles of psychoanalysis and the analysts'' formation. In the final considerations, we state that the institutional demand of a meaning for the case is a great difficulty for the analyst since he works from a place of 'not-knowing"

O sintoma na psicanálise e na psicopedagogia: do que se trata?

This paper aims to discuss the concept of symptom in psychopedagogy and psychoanalysis, drawing the consequences for the direction of treatment for each of these fields. Learning Problems has been the name given by various fields of knowledge to what does not happen as expected in the learning process. To address these problems several professionals are called upon. Faced with this demand a new field of knowledge is created: the psycho-pedagogy. In Brazil, it is established as a field of work and research from the contributions of Alicia Fernández. This author, supported by the work of French philosopher and educator Sara Paín, takes the concept of Freudian-Lacanian symptom as a fundamental concept to read the so-called "learning problems". Given this one must question whether the concept of symptom Fernandez is really the same as psychoanalysis. Are they the same? If yes, how to sustain as different fields? If not, what are consequences for the direction of treatment for each of these fields? For this study, the theoretical works of Alicia Fernández and Sara Pain were read aiming to clarify the concept of symptom in psychopedagogy. To discuss the psychoanalytic concept of symptom we turned to the texts of Freud, Lacan and commentators in which this issue is discussed. The results show that Pain and Fernandez seek psychoanalysis as a theory to be coupled with others to solve the learning problems. The concept of symptom as a return of the repressed and as an indicator of a sense to be found in the history of the subject is similar to the psychoanalytical one, however, in psychopedagogy other fields of knowledge and techniques are used as reference and these are sometimes incompatible with the concept of symptom presented. The use of psychological tests for the diagnosis, the idea of transference without the notion of subject supposed to know and the proposed treatment are indications of a different treatment approach from what the ethics of psychoanalysis proposes

Utilização de sílica gel organofuncionalizada para adsorção de íons metálicos em solução aquosa

In this work the organosilanes aminopropyltriethoxysilane, 3-mercaptopropyltryethoxisilane and n[-3-(trimetoxisilyl)propyl]ethylenetriamine, as well as tetraethylortosilicate (TEOS), were employed to produce, by sol-gel method, organofuncionalized silicon samples. The prepared samples were characterized by elementar analys by thermogravimetry and infrared spectroscopy. Those samples were employed to adsorb Cd2+, Pb2+, Ni2+ and Zn2+ from aqueous solutions (10, 20, 40, 60 and 80 mg L-1). In typical experiments, 50 mg of the organometrix was suspended in 20 mL of metal cation solutions at four different contact times: 30, 60, 90 and 120 minutes. The total amount of adsorbed cations were measured by atomic absorption spectrometry. To all investigated matrices, the following adsorption capacity was observed: Ni2+ > Zn2+ > Cd2+ > Pb2+. Such sequence is closely related with the cation radius, as well as the cation hardness

Por uma pedagogia do oprimido midiático: meios de comunicação e suas intervenções na escola

En este trabajo nos ocupamos de la convergencia de la fotografía, el vídeo y la música, intermediado por una estación de radio en la escuela, instalada en la escuela Municipal de Djalma Maranhão, Natal, Rio Grande do Norte, en una clase de 5º año de jóvenes y adultos en el año escolar 2007. Se analizan las intervenciones causados los que participan en la vida escolar, a partir de las actividades realizadas por ellos, en la producción de programas de radio. Los procedimientos metodológicos sobre la base de la etnometodologia (COULON, 1995a, 1995b), en la investigación cualitativa (BOGDAN, BIKLEN, 1999, DENZIN y LINCOLN, 2006), participante como observador (MAY, 2004) y la investigación-acción (THIOLLENT, 1992). La comprensión de Paulo Freire en la comunicación e la educación es nuestro principal referente teórico. Los experimentos citados en los medios de comunicación revelaron varias posibilidades de mejora en la enseñanza y el aprendizaje, como el aumento de la autoestima de los estudiantes, social y de inclusión educativa de personas con discapacidad, disminución de la timidez y facilitar la comunicación entre los sujetos, lo que permite el diálogo entre ellos, intervino en sus relaciones sociales, más allá de los límites de la escuela. La investigación confirma, entonces, que la comunicación y la educación son parte de la misma naturaleza

A educação informal para o consumo infantil e juvenil na televisão e na mídia

The consumption has become a major pillar of modern capitalism and at the same time, one of the factors that relate to social inequality. Karl Marx developed the theory of historical materialism which maintains a history of society determined by class struggle and the! exploitation of man by man. Considered to be overtaken by those who believe that Marxism is synonymous with real socialism, the Marxist ideals seem more present than in the Western world which each individual takes the individualization (loss of sense of public and collective) and the alienation by the work. Weassumed we could work on these issues in student education, even in elementary school, through questioning of the consumer society, with the criticism of television and the media, the main promoter of the current sense of consumption, as an initial step that could lead to future autonomy of theindividual. The theory of ideology and ideas of Paulo Freire's liberating education theory permeated the experience that happened as a participant observation of groups in the discipline of sociology in the unit 2 of the Colégio Pedro II in Rio de Janeiro, the state capital, an institution under the direct administration Ministry of Education. Wehave found fertile ground in which the students were able to understand and question the meaning of advertising media
