A dimensão social do desenho: um estudo sobre as interações no processo de (re) construção imagética da criança no Ensino Fundamental

In the historical-cultural perspective, the drawing is processed by means of a shared and complex way, under diverse relations with the other and with the immersed signs of the culture. That is, something constituted by the social interactions and that can modify the structure of the psychological functions, therefore as socialized sign, propitiates the incorporation of the functions socially. In this way, the figuration carrier sensitive and established meanings historically disclosing the shared experiences and the ways of the subject to think and perceive the world. Such reflections gave shape to the main problem of this research: how to think over about the drawing at the school to incide in the reconstruction of the childs imaginative language? Under such perspective, this work deals with the interactions in the production process of the drawing of the children in a context of teach-Iearning of the elementary school having as goal to analyze the interactions established in the cIassroom in the process of production of the drawings; to propose situations of learnings that favor the advance graphical expression of the students; and to identify in the interactive games some relations between body expression and drawing. For its accomplishment, it was opted for the construction process based in the collaborative investigation by the fact to propitiate negotiations, sharing and confrontation of ideas, becoming possible a joint construction of the knowledge. For this research, the researcher and the collaborating teacher, as well as the involved children, become themselves into co-authors of the context studied. As locus of the research, it was chosen a first cycle class, with 30 students, from Municipal School Profª. Emília Ramos (Natal/RN - Brazil), whose election took in account the fact of this school to constitute in a promotional space of reflections and professional development of teachers in service and, at the same time, for presentinglimitations theoretic- methodological in the field of teaching for Arts. In the process of the research, it was perceived that the children with the support of the verbal language formulates meanings on the seen and imagined object, printing lines and forms that if overlap to the physiological aspects of the visual perception. That is, the drawing discloses a reality appraised, enriched for the picked up vision of the image, but the meanings established for the author, or observer who becomes it perceivable and identified. In the systemizing situations, it was observed that the teaching-Iearning process of the drawing, implies a co-construction between teachers and learners. And, moreover, the necessity to interlace emotion and cognition by means of plastic-corporal interactions that foment drawing experiences, whose process concurs for the imagenative reconstruct of the apprentices

Ensino do processo de enfermagem: significados percepções docentes na formação do enfermeiro

The implementation of the nursing process should be experienced by all nurses during their formative years. However, the lack of implementation of the nursing process for care planning during the educational process and the existing disorder in the formation process prompted the following research questions: What is the meaning of teaching the nursing process to the nursing professors? Do nursing professors use strategies and methods that promote critical thinking in their students? The objective of the study was to analyze the meaning that teaching of the nursing process has for the nursing faculty of the bachalaureate nursing course. Qualitative descriptive study conducted with a sample of 30 faculty members that taught nursing care courses in the nursing program of the Federal University of Rio Grande do Norte (UFRN) in Natal, RN. Two instruments were used, a questionaire and an interview guide. The questionnaire was designed to obtain sociodemographic, educational and work information, of faculty activities and of the teaching of nursing care. The guide was composed of five open questions regarding the understanding and perceptions of the nursing process, its utilization in teaching, and the nursing care teaching strategies. Interview data were submitted to content analysis techniques and interpreted according to the principles of Symbolic Interactionism. Six categories related to the analytical themes were identified: the nursing process as the guide for the care actions; clinical rationality; use of the care activities; teaching relevance; teaching barreirs; teaching strategies with focus on the abilities and competencies of the clinical rationale. Faculty perceptions regarding the teaching of the nursing process; nursing care approach in the nurses‟ formation. The study indicates that the participants understand the relevance of the nursing process a work instrument and that the use of this method during the nurses‟ formation enhances the abilities and competencies for critical thinking that is essencial for care. The strategies for teaching of abilities and competencies were identified, however the nursing faculty should use codes, direction and the influence so that the students can Interact and therefore stimulate the use of the nursing process

Modos de aplicação de zinco na nutrição e no crescimento inicial da cultura do arroz

The present research had he objective to evaluate rice response to zinc application forms on the nutrition, growth and dry matter production, in vase conditions. The experiment was carried out in a completely randomized design, with five treatments (leaf Zn, incorporated Zn, located Zn, Zn saw seed and witness - whitout zinc), in four repetitions during two cycles of cultivation with 42 days of duration each. Plastic vase of 7L, were filled with Red Distrofic Latosol (Zn = 0.3 mg dm(-3) in DTPA). The application of Zn saw soil in both culture of the rice improved its level in the soil, being distinguished it from located form. In the first cycle, the application of Zn saw leaf promoted greater absorption of the nutrient for the rice plants, while in the second cycle leaf application was followed by the saw soil incorporated. The biggest dry matter production occurred with application of leaf saw in the first cycle and saw soil (incorporated and located) in the second rice cultivation.

Modos de aplicação de zinco na nutrição e na produção de matéria seca do milho BRS 1001

The culture of the maize is responsive the fertilization with zinc, however, its efficiency can be affected by the method of aplication. Thus, this work had as objective to evaluate the effect of the methods of zinc application in the nutritional state and the initial growth of the culture of the maize. The experiment was in a completely randomized design, with five treatments in four repetitions. The experimental unit was composed for a pot (7 L) filled with a distrofic Red Latosol, clayey texture, with four plants of maize. The treatments had been constituted by four ways of zinc application: in the soil incorporated (3 mg Zn dm(-3)), and located (1 mg Zn dm(-3)); foliar (solution of 23 mg Zn L(-1)); e in seed (40 g Zn kg(-1) of seed) and beyond the witness (control). The treatments had been applied during two cultivation of 42 days, except the Zn incorporated in the soil. In the end of each culture, the cut of the plants for the evaluation of the growth variable (leaf height, number, the diameter of stems and dry matter) and the determination of the zinc text was carried through in the soil and the aerial part. The zinc application promoted increment in the height and the production of matter of the maize. The zinc application soil (incorporated and located), foliar and seed had been similar in the initial development of the culture, however, the foliar way promoted greater absorption of the nutrient for the plant.

Modos de aplicação de zinco na nutricão e na produção de massa seca de plantas de trigo

Zinc application methods can affect the nutrition and the initial development of the wheat. Thus, the aim of this work was to analyze the different ways of Zn application in the soil, on nutrition and on dry matter production. A completely randomized experimental design with four replications was used. The experiment was composed by the following Zn application treatments: control (no zinc application); soil incorporation, furrow located, seeds treatment and leaf pulverization. The experimental unit was composed of a pot filled with 7 L of soil. Morphological traits for each plant were determined on 52 days after emergence by the evaluations of plant height, internodes number, tillers number and aerial part dry matter. Still, the soil and plant chemical analysis was accomplished. The furrow located method provided larger concentrations of the micronutrient available. The zinc application methods did not influence the initial growth of the wheat plants. The zinc concentration in leaves was influenced by the different application methods, being the leaf pulverization the one that was caused the largest zinc accumulation on aerial part dry matter.

Efeito de modos e épocas de aplicação de gesso e calcário sobre a cultura do feijoeiro (Phaseolus vulgaris L.) cv. Carioca-80

Instalou-se sobre um latossolo vermelho-escuro textura média, um experimento cujo objetivo foi avaliar a influência de modos e épocas de aplicação de gesso e de calcário sobre algumas características nutricionais e tecnológicas da cultura do feijoeiro irrigado. Utilizou-se no experimento o delineamento em blocos casualizados em esquema fatorial (4x3)+2 com quatro repetições, correspondendo a 4 modos de aplicação de gesso e/ou calcário, 3 doses de gesso e 2 tratamentos adicionais. Os resultados mostraram que: o uso do gesso proporcionou maiores teores de Ca nos grãos e consequentemente maior tempo para o seu cozimento. A associação gesso e calcário propiciou aumento no teor de S das folhas e também no peso de 100 grãos, quando comparado à utilização de apenas gesso. A relação de hidratação diminuiu com o aumento das doses de gesso quando utilizou-se os modos de aplicação M1 (gesso aplicado no solo 45 dias antes da semeadura) e M2 (gesso e calcário aplicados conjuntamente aos 45 dias antes da semeadura).

Análise dos Modos Ressonantes em Antenas de Microfita sobre Substratos Iso/Anisotrópicos por Técnicas da Ressonância Transversa

Neste trabalho, são utilizadas a Técnica da Ressonância Transversa (TRT) e a Técnica da Ressonância Transversa Modificada (MTRT), para a determinação das freqüências dos modos ressonantes de antenas de microfita com patch quadrado, retangular e circular e com substratos isotrópicos e anisotrópicos. Para isso, é proposto um modelo da cavidade equivalente, onde a antena tipo patch retangular é representada como sendo a superposição de duas linhas infinitas em microfita, uma de largura W, representando a dimensão que expressa a largura do patch, e a outra com largura L, representando a dimensão que expressa o comprimento do patch. A avaliação da eficiência e aplicabilidade dos métodos citados é realizada comparando-se com resultados experimentais e obtidos através de outras técnicas. Três situações serão verificadas: estruturas com substrato infinito, estrutura com substrato tipo pedestal e estruturas com substrato truncado além dos limites da fita metálica. Os resultados obtidos demonstram que as técnicas de análise de onda completa utilizadas neste trabalho, por um formalismo matemático mais rigoroso, são eficientes e precisas tanto na aplicação em estruturas com substrato isotrópico como nas que possuem substrato anisotrópico. Inicialmente são consideradas apenas as estruturas com substratos isotrópicos, com diferentes constantes dielétricas, e é avaliada a influência da largura do substrato sobre as freqüências dos modos ressonantes das antenas. Posteriormente, a análise do truncamento do dielétrico é realizada para estruturas com substrato anisotrópico. Em todos os casos, os resultados experimentais, obtidos a partir da construção de protótipos, são confrontados com os obtidos a partir de simulação, utilizando as técnicas TRT e MTRT. No final, as técnicas descritas são utilizadas para antenas tipo patch circular, sendo utilizada uma técnica de equivalência para transformar a antena circular em outra quadrada ou retangular equivalente, dependendo do modo que se queira encontrar. Os resultados obtidos são então analisados, observando-se uma boa concordância e indicando a viabilidade do método. Após isso, são apresentadas as conclusões e sugeridos alguns temas para a continuidade deste trabalho

O masculino em revista: mídia, discurso e modos de subjetivação afetivos-sexuais

This dissertation has the thematic of the sexual affection of the masculine subjectivity within texts of Universo Masculino and Men‟s Health magazines as object of analysis. The central objective was to describe and interpret the theme on the masculine subjectivity in discourses about the affection of sexuality materialized in discourse practices in those magazines. The main point of the research matters how the discourse structures of texts in those magazines make it possible to comprehend the meanings produced about the masculinity nowadays. On the perspective of the thematic trajectory what consists the main aspect that concerns the leading of corpus in the research under the French discourse analysis, we have searched, in reports of those magazines, an arch-genealogy of masculinity, from a specific sexual-affection disposable of our mediate culture. The analytic trajectory enables us to conclude that the thematic trajectory about the sexual affection of the masculine subjectivity produces a semantic way that confirms hegemony and hetero-normative ideals, rather than what proposes new performances on the masculine subjectivity experiences. In its real effects, such mediate discourse practice pursues to link certain sexual affection knowledge to the male individual‟s lifestyle today, from the thematic choices, enunciation modalities and discourse strategies which are specific to the masculine media

Controle por modos deslizantes com compensação difusa aplicado a sistemas com descontinuidade

The development of non-linear controllers gained space in the theoretical ambit and of practical applications on the moment that the arising of digital computers enabled the implementation of these methodologies. In comparison with the linear controllers more utilized, the non -linear controllers present the advantage of not requiring the linearity of the system to determine the parameters of control, which permits a more efficient control especially when the system presents a high level of non-linearity. Another additional advantage is the reduction of costs, since to obtain the efficient control through linear controllers it is necessary the utilization of sensors and more refined actuators than when it is utilized a non-linear controller. Among the non-linear theories of control, the method of control by gliding ways is detached for being a method that presents more robustness, before uncertainties. It is already confirmed that the adoption of compensation on the region of residual error permits to improve better the performance of these controllers. So, in this work it is described the development of a non-linear controller that looks for an association of strategy of control by gliding ways, with the fuzzy compensation technique. Through the implementation of some strategies of fuzzy compensation, it was searched the one which provided the biggest efficiency before a system with high level of nonlinearities and uncertainties. The electrohydraulic actuator was utilized as an example of research, and the results appoint to two configurations of compensation that permit a bigger reduction of the residual error

Adubação com boro em batata-doce: efeito das fontes, doses e modos de aplicação

Boron (B) fertilization can result in high yield and better sweet potato storage roots quality. However, there is few works about this subject. The objective was to evaluate the yield of sweet potato crops in response to B sources, rates and application form. The experimental design was complete randomized blocks, in factorial outline ((2x2x2)+1), with three replications, which resulted of the combination of sources of B (boric acid and borax), application form (via soil and via foliar) and doses of B (1 and 2 kg ha(-1)) and a control treatment (without B). There was no interaction between the factors studied for the commercial yield of sweet potato. No significant differences was found between B sources and application form, but they showed higher yield than the control treatment. Additionally, sweet potato yield increade with application of 2 kg ha(-1) of B.

Efeitos de fontes de nitrogênio e de modos de aplicação do adubo fosfatado (32P) sobre a porcentagem de utilização do fósforo do superfosfato simples pelo trigo (Triticum aestivum L.)

No programa de pesquisa a respeito da adubação da cultura de trigo, utilizando isotopos (32P e 15N), o plano do ano 1971/1972 tinha, entre outros objetivos, a finalidade de determinar a porcentagem de aproveitamento do fósforo pelo trigo, em função do modo de aplicação e interação com fontes de nitrogênio. Oexperimento foi instalado em solo pertencente a ordem Ultisol e grande grupo Podzólico Vermelho-Amarelo (Pelotas-RS), contendo 9 ppm de P. Os adubos nitrogenados: sulfato de amônio, uréia e nitrato de amônio, na dose de 120 kg/ha, foram aplicados metade no plantio (ao lado e abaixo das sementes) e metade em cobertura, na fase do perfilhamento. O fósforo radioativo, na forma de superfosfato simples, foi aplicado na dose de 30 kg P2O5/ha de duas maneiras: junto com as sementes ou junto com o adubo nitrogenado aplicado no plantio. Amostras de plantas de trigo foram coletadas entre perfilhamento e espigamento e determinaram-se os pesos de matéria verde e seca, as porcentagens de P total e de P proveniente do fertilizante contidos na matéria seca e a porcentagem de utilização do fósforo aplicado (% UP). Pode-se concluir que a aplicação de nitrogênio é necessário para se obter maio res % UP, mas não há diferenças entre as fontes. Os modos de aplicação do fósforo não diferiram entre si quanto a % UP.

Alternância no uso dos modos indicativo e subjuntivo em orações subordinadas substantivas: uma comparação entre o português do Brasil e o francês do Canadá

The purpose of this work is to analyze the use of the indicative mood, instead of the subjunctive prescribed by the normative grammar, in complement clauses introduced by the conjunction que in Brazilian Portuguese. Contexts of use of the subjunctive according to grammatical prescription, and contexts of fluctuation on the use of that verbal mood were analyzed, in an attempt to investigate what interferes on the choice of the mood by the user of the language. This study is based on North-American Functional Linguistics theoretical perspective, oriented to analyzing language in use, in the light of the principles of grammaticalization and markedness. The results obtained support that the contexts that favor the indicative over the subjunctive are those composed by a complement clause functioning as a direct object the unmarked clause of all complement clauses and by a verb on the main sentence that belongs to the semantic field of low certainty, corresponding to the epistemic sub-mode the unmarked category of the deontic sub-mode. The results indicate that pragmatics and semantics factors influence the language user on the choice of the verbal mood. This research also presents comparative data on the use of the indicative mood in place of the subjunctive in Brazilian Portuguese and Canadian French, aiming to providing suggestions on language teaching

Modos de ler, formas de escrever a literatura enquanto objeto da ficção de Enrique Vila-Matas

Este trabajo busca analizar cómo algunos aspectos presentes en la obra de ficción del escritor catalán Enrique Vila-Matas permiten pensar las prácticas de la escritura literaria contemporánea. A partir de una forma híbrida que reconsidera las relaciones tanto entre los géneros como entre los discursos crítico y de ficción, la obra del autor se propone reflexionar sobre sus propias posibilidades en el contexto sociocultural contemporáneo. De este modo, a través de una ficción que muchas veces adquiere los atributos del ensayo, Vila-Matas trae al centro de sus enredos la discusión de cuestiones relacionadas con los impases de una escritura que vuelve su atención para el destino de una tradición literaria desvinculada de los preceptos meramente mercadológicos contemporáneos. Su manera crítica de abordar la literatura y la experimentación en busca de nuevas posibilidades permite asociarlo tanto a Laurence Sterne como al proyecto literario de Jorge Luis Borges. Estos autores tienen propuestas que tratan de superar los límites del texto, ya que ahí está el deseo de acogerse a la ficción para demostrar la inestabilidad de los elementos de una cultura, apropiándose y desestabilizando los discursos y las claras distinciones entre los saberes. En este sentido, las diversas formas en que Vila- Matas se apropia de los textos de otros y construye una obra de carácter fuertemente intertextual denuncian jerarquizaciones y modos de circulación de textos que permiten aproximarse de la tensión existente entre temas como influencia, citación, prácticas de lectura y escritura
