Inserção do Design em Micro e Pequenas Empresas: o caso de duas indústrias moveleiras no Estado do Rio Grande do Norte /

This work aims to promote design aspects into furniture Small and Medium Enterprises (SME s) at Rio Grande do Norte State. The final outcome will be an increasing on their competitiveness as well as consider design as key strategic aspect for their business. As a consequence, the results are based on two SME companies from the furniture sector located at Natal/RN. The study is based on a literature research followed by a management diagnosis for each company. The diagnosis was base don interviews with the entrepreneurs and their employees as well as meetings, participant observations and document analysis. Based on this analysis, specific aspects were implement in order to boost the production line as well as the product development process (PDP) and the development of a prototype. The results have indicated some limitation of these companies regarding their low technological on their production line, poor management and work skills as well as low perception of design as a competitive tool. Regardless these results, it was observed that design has brought an important contribution for cultural changes within companies as well as for the development of better quality and competitive products

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

Uma abordagem comportamental para inserção de robôs em ambientes culturais

In this work, we propose methodologies and computer tools to insert robots in cultural environments. The basic idea is to have a robot in a real context (a cultural space) that can represent an user connected to the system through Internet (visitor avatar in the real space) and that the robot also have its representation in a Mixed Reality space (robot avatar in the virtual space). In this way, robot and avatar are not simply real and virtual objects. They play a more important role in the scenery, interfering in the process and taking decisions. In order to have this service running, we developed a module composed by a robot, communication tools and ways to provide integration of these with the virtual environment. As welI we implemented a set of behaviors with the purpose of controlling the robot in the real space. We studied available software and hardware tools for the robotics platform used in the experiments, as welI we developed test routines to determine their potentialities. Finally, we studied the behavior-based control model, we planned and implemented alI the necessary behaviors for the robot integration to the real and virtual cultural spaces. Several experiments were conducted, in order to validate the developed methodologies and tools

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

Perspectivas de inserção da energia solar fotovoltaica na geração de energia elétrica no Rio Grande do Norte

The generation of electricity in Brazil is predominantly renewable, with internal hydraulic generation being more than 70% of its energy matrix. The electricity rationing occurred in 2001 due to lack of rain, led the country to increase the participation of alternative energy sources. This need for new sources of energy makes the regional potential to be exploited, which configures the change of generation model from centralized generation to distributed generation. Among the alternative sources of energy, the solar energy is presented as very promising for Brazil, given that most of its territory is located near to the equator line, which implies days with greater number of hours of solar radiation. The state of Rio Grande do Norte (RN) has one of the highest levels of solar irradiation of the Brazilian territory, making it eligible to receive investments for the installation of photovoltaic solar plants. This thesis will present the state-of-the-art in solar photovoltaic power generation and will examine the potential for generation of solar photovoltaic power in Brazil and RN, based on solarimetrics measurements conducted by various institutions and also measurements performed in Natal, the state capital

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

A escrita do texto acadêmico na graduação: modos de utilização de conceitos teóricos de uma área de conhecimento

In this study we have developed a discussion about academic text production in the undergraduate course of Literature and Languages. Specifically, we are going to analyze the monographic text writing in order to verify the meaning effects created from the ways of showing other s discourses that constitute a written production. As a means to do that, we are going to answer the following question: How does a young researcher make use of a theory in order to be part of a particular scientific community? We aim to: 1) analyze the linguistic resources, like quotations and signs of cohesion that demonstrate the other s voice presence in academic writing; 2) observe the meaning effects produced through the ways that the one who writes shows the other s voice in the written text. Firstly, we have selected 23 (twentythree) monographs produced in the last five years by students from a Literature and Languages undergraduate course in a determined public university. However, in this study, we have analyzed just 02 (two) different monographic texts. To develop such an investigation, we have inquired Kuhn s concept of science, which shows the existence of different meanings of science production in the course of the centuries. It allows us to define academic writing as science production that develops and contributes to knowledge production. With the purpose of restricting the meaning of writing conception, we have relied on Coracini, who assumes that all writing production is the registration of the self, in other words, writing comes from the subject s intervention, it is to say that only an imposition of the self guarantees the subject as author of what he writes. We have as theoretical basis the following concepts: 1-) Authier-Revus s enunciative heterogeneity, that allowed us to analyze the written marks of the other in the monographic writing; 2-) Pêcheux s reformulation-paraphrase and Orlandi s polysemy and paraphrase, concepts that present notions of productivity and creativity as ways of meaning production, and allows us to observe how the process of language production in academic writing is established; 3-) Rossi-Landi s concept of exchange-value and use-value, which consider language as a linguistic work, allowing us to verify the differences between use and social functionality in a determined theory; and 4-) Possenti s notion of authorship indicia, with which we have identified attitudes that make the one who writes author of his own text. We have verified that writing characterized for repetition and reproduction may develop a meaning effect that constructs the idea that writing production promotes an author, a concept or a theory. We have also realized that a written text that restricts itself to reproduce other authors discourses and does not articulate a theory with data analysis or with work methodology, when evaluated is approved and legitimates itself as scientific production. That demonstrates the existence of academic productions that do not develop any functionality of the employed theory. The text works as a means to promote its theoretical concepts, and theory. It is to say that the theoretical foundantion, which usually is a way to argue and sustain scientific production, does not have any function. Thus, we consider that the way someone shows the other s discourse in academic writing may work as a way to underline what the other asserts to the detriment of the researcher s words. This fact allows us to comprehend that a way of writing may evidence a meaning effect of the author s, theory s or theoretical concepts promotion

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

Perspectivados cirurgiões-dentistas sobre a inserção da fisioterapia na atenção básica de saúde

This work aims at investigating the surgeons-dentists acceptability in the field of public health in the city of Natal, State of Rio Grande do Norte, about the possibility of medicinal plants insertion in basic attencion of health. Moreover, it searchs to know if during their professinal formation it had some theoretician-pratical basement on this subject, as well as investigating their confidence on the medicinal plants. The basic motivation for developing this study is the possibility of contributing to the insertion of a tradicional health pratical at public assistance scope, endorsed by popular use, but now scientifically proven. For in a such way, the medicinal plants use is emphasized as a way to be followed to increase basic pharmaceutical assistance, improving the acess to the medicine and diminish expenses. Following this logic, family health program constitutes the way through which this pratical will be available to the users of health services. The research was done over thirty surgeonsdentists, all ofthem pertaining to public service ofNatal, state ofRio Grande do Norte. It was used, as research instrument, semi-estructured interview associated with methodological analysis user s speeches. On this form, this work is inserted in a trend observed nowadays not only in Brazil, where the use of the medicinal plants has been stimulated and defended to be inserted at programs ofprimary attenction of health

Protocolo de Quioto e as possibilidades de inserção do Brasil no Mecanismo de Desenvolvimento Limpo por meio de projetos em energia limpa

Este artigo pretende estudar a inserção do Brasil no Mecanismo de Desenvolvimento Limpo (MDL) do Protocolo de Quioto, por meio de projetos em energia limpa, enfatizando a cooperação entre países desenvolvidos e em desenvolvimento e visando as ações práticas que esse mecanismo permite desenvolver para se alcançar o desenvolvimento sustentável e para conter o aquecimento global. Para isto, realizou-se extensa revisão bibliográfica dos acordos internacionais referentes às mudanças climáticas e de livros e artigos sobre a inserção brasileira no Protocolo de Quioto e no Mecanismo de Desenvolvimento Limpo. O Protocolo de Quioto é um acordo internacional que prevê a redução das emissões de gases de efeito estufa por intermédio de mecanismos flexibilizadores. O Mecanismo de Desenvolvimento Limpo é o único que permite a participação de países em desenvolvimento, para que eles reduzam emissões por meio de projetos que busquem o desenvolvimento sustentável. Neste contexto, o Brasil surge como um país atrativo para o recebimento destes projetos, por sua vocação para desenvolver fontes alternativas de energia e pela sua liderança no processo negociador do Protocolo. O MDL configura-se, portanto, em uma grande oportunidade para o Brasil, visto que esses projetos representam uma fonte de recursos financeiros para que o país busque o desenvolvimento sustentável, além de incentivarem um maior conhecimento científico e a adoção de novas tecnologias.

Psicose e toxicomanias: um estudo psicanalítico

This paper is a case study that aims to discuss the effects of drug abuse by a person with psychotic structure from a psychoanalytical perspective. The interest in this subject was born from an internship experience in the Mental Health area in which a psychotic patient had a drug abuse problem and the service treating him had difficulties dealing with this. In order to accomplish the objective of this work four theoretical chapters were written and the case is discussed throughout them articulating the theoretical issues with clinical practice. A literature review revealed that Freud and Lacan did not dedicate themselves to the study of the effect of drug use by psychotic patients but they made important contributions unfolding the theoretical and clinical psychoanalytical practice. Contemporary psychoanalytic authors suggest that the drug use made by psychotics differs from the use by neurotics, because of the particularity of the psychotic structure. It was found that drug use in psychosis can operate in three different ways: the first refers to drug use as substitute of a missing signifier helping the psychotic patient building a social bond. The second function is to intensify psychotic phenomena and the third function is to operate as an attempt to diminish those same phenomena. We conclude that, while the use of drugs in neurosis provides an individualist way of satisfaction, that excludes social aspects. For psychosis such use may operate differently and may play a role in social integration, among others effects. Such discussion can help move forward the direction of treatment of psychosis when the case involves drug use
