Do modelo geométrico ao modelo físico: o tridimensional na educação do arquiteto e urbanista

In the teaching practice of architecture and urbanism in Brazil, educational legislation views modeling laboratories and workshops as an indispensable component of the infrastructure required for the good functioning of any architectural course of study. Although the development of information technology at the international level has created new possibilities for digital production of architectural models, research in this field being underway since the early 1990s, it is only from 2007 onwards that such technologies started to be incorporated into the teaching activity of architecture and urbanism in Brazil, through the pioneering experience at LAPAC/FEC/UNICAMP. It is therefore a recent experiment whose challenges can be highlighted through the following examples: (i) The implementation of digital prototyping laboratories in undergraduate courses of architecture and urbanism is still rare in Brazil; (ii) As a new developing field with few references and application to undergraduate programs, it is hard to define methodological procedures suitable for the pedagogical curricula already implemented or which have already been consolidated over the years; (iii) The new digital ways for producing tridimensional models are marked with specificities which make it difficult to fit them within the existing structures of model laboratories and workshops. Considering the above, the present thesis discusses the tridimensional model as a tool which may contribute to the development of students skills in perceiving, understanding and representing tridimensional space. Analysis is made of the relation between different forms of models and the teaching of architectural project, with emphasis on the design process. Starting from the conceptualization of the word model as it is used in architecture and urbanism, an attempt is made to identify types of tridimensional models used in the process of project conception, both through the traditional, manual way of model construction as well as through the digital ones. There is also an explanation on how new technologies for digital production of models through prototyping are being introduced in undergraduate academic programs of architecture and urbanism in Brazil, as well as a review of recent academic publications in this area. Based on the paradigm of reflective practice in teaching as designed by Schön (2000), the experiment applied in the research was undertaken in the integrated workshop courses of architectural project in the undergraduate program of architecture and urbanism at Universidade Federal do Rio Grande do Norte. Along the experiment, physical modeling, geometric modeling and digital prototyping are used in distinct moments of the design process with the purpose of observing the suitability of each model to the project s phases. The procedures used in the experiments are very close to the Action Research methodology in which the main purpose is the production of theoretical knowledge by improving the practice. The process was repeated during three consecutive semesters and reflection on the results which were achieved in each cycle helped enhancing the next one. As a result, a methodological procedure is proposed which consists of the definition of the Tridimensional Model as the integrating element for the contents studied in a specific academic period or semester. The teaching of Architectural Project as it is developed along the fifth academic period of the Architecture and Urbanism undergraduate program of UFRN is taken as a reference

Significados e percepções do homem diante da gravidez de sua companheira com síndromes hipertensivas

The general aim of the research was to comprehend the Social Representations constructed by the man in the face of his companion s risk pregnancy caused by hypertensive syndromes. The study is of exploratory and descriptive character in a qualitative approach developed at two public maternity hospitals, both located in Natal-RN, with 65 men whose wives had undergone high-risk pregnancy. The project was submitted to the Ethics on Research Committee of the Federal University of Rio Grande do Norte, Brazil (CEP-UFRN), with favorable report no. 81/07. For data collection, the following multimethods were employed: a word free association test; a projective test for registering mental images; and a semistructured interview schedule. The speech contents were analyzed in accordance with the Theory of Social Representations and complemented by the Central Nucleus Theory. The discussion of the results was grounded on literary findings of the companion s participation in pregnancy as well as in risk pregnancy associated with hypertensive syndromes. The data showed fear as representation s central nucleus, while recollections of that feeling referred to death of both companion and child in addition to fear of the unknown. The categories preoccupation and carefulness, other feelings, and clinical picture of the disease represented components of the peripheral nucleus. The results concerning mental images followed the same category criteria of the word free association test fear, other feelings, preoccupation, carefulness, and clinical picture of the disease. After being processed in accordance with the principles of content analysis, the statements originated three thematic unities: fear and insecurity in the presence of the companion s risk pregnancy; attitudes of carefulness to the risk pregnancy of the partner; and humanized assistance during the companion s risk pregnancy. Considering the results, the conclusion is that the partner s risk pregnancy caused by hypertensive syndromes represents, for the man, feelings of fear, preoccupation, insecurity, lack of acceptance and information, as well as attitudes of carefulness. The results reveal necessity of reorganizing the obstetric assistance with an eye to including the man as participant in the reproductive process. That demands extension of humanized carefulness to the companion with a view to make him an active coadjutor in the assistance of high-risk pregnant

Representações sociais de enfermeiros brasileiros e portugueses sobre o estresse em serviço de urgência

This study aimed to analyze the social representations of Brazilian and Portuguese nurses on stress in the emergency service. A semi-structured interview and the free word association test, with "stress" as the inductive stimulus, were used as research instruments. Data were collected from 120 nurses, being 60 from an emergency hospital in the city of Natal, Brazil and 60 from an urgency hospital in the city of Aveiro, Portugal. Data from the word association test were analyzed with the EVOC 2002 program, after thematic categorical content analysis, enabling construction of a data bank. Data gathered from the interview were analyzed by ALCESTE 4.8 software. Nurse represent the stress in the urgency department as a generation of physical and mental detrition where adaptation is unsatisfactorily, resulting in the onset of fatigne, irritability, lack of concentration, lack of motivation, pessimism, impaired interpersonal relationship and low productivity. The solution is part of a complex whole, which demands an integrated way of acting that has demanded increasingly professional attitudes based on multidisciplinarity

First record of Trypanosoma sp. (Protozoa: Kinetoplastida) in tuvira (Gymnotus aff. inaequilabiatus) in the Pantanal wetland, Mato Grosso do Sul State, Brazil

O objetivo do presente estudo foi reportar a infecção por Trypanosoma sp. em tuviras (Gymnotus aff. inaequilabiatus) oriundas do Pantanal Sul-mato-grossense, Brasil. Dez peixes provenientes do rio Paraguai, Pantanal Sul-mato-grossense, foram avaliados quanto à presença de hemoflagelados. Tripomastigotas de Trypanosoma sp. foram observados nas extensões sanguíneas de três peixes (30% de prevalência), e algumas formas encontravam-se em divisão. Por meio do exame a fresco e da centrifugação do sangue em capilar de hematócrito como métodos para diagnóstico, a taxa de prevalência foi de 80%. Esse é o primeiro relato de Trypanosoma sp. em tuviras no Brasil.

Reconhecimento de voz através de unidades menores do que a palavra, utilizando Wavelet Packet e SVM, em uma nova estrutura hierárquica de decisão

The automatic speech recognition by machine has been the target of researchers in the past five decades. In this period have been numerous advances, such as in the field of recognition of isolated words (commands), which has very high rates of recognition, currently. However, we are still far from developing a system that could have a performance similar to the human being (automatic continuous speech recognition). One of the great challenges of searches for continuous speech recognition is the large amount of pattern. The modern languages such as English, French, Spanish and Portuguese have approximately 500,000 words or patterns to be identified. The purpose of this study is to use smaller units than the word such as phonemes, syllables and difones units as the basis for the speech recognition, aiming to recognize any words without necessarily using them. The main goal is to reduce the restriction imposed by the excessive amount of patterns. In order to validate this proposal, the system was tested in the isolated word recognition in dependent-case. The phonemes characteristics of the Brazil s Portuguese language were used to developed the hierarchy decision system. These decisions are made through the use of neural networks SVM (Support Vector Machines). The main speech features used were obtained from the Wavelet Packet Transform. The descriptors MFCC (Mel-Frequency Cepstral Coefficient) are also used in this work. It was concluded that the method proposed in this work, showed good results in the steps of recognition of vowels, consonants (syllables) and words when compared with other existing methods in literature

Capacidade, dotação, talento, habilidades: uma sondagem da conceituação pelo ideário dos educadores

Embora o escopo deste trabalho seja de origem teórica, relata um estudo exploratório que busca situar a base de conceituação em Educação Especial para alunos Dotados e Talentosos, no Brasil, captando as definições compreendidas por profissionais da educação pela sondagem de sua opinião sobre que termos e expressões são usados, com que significados e em que situações. Os sujeitos incluíam 80 educadores interessados ou envolvidos na área (Grupo A) e 107 professores da rede pública no interior de São Paulo (Grupo B). Há poucas diferenças de opinião entre os sujeitos, nos dois grupos, com algumas exceções, principalente em questões relacionadas a nível de conhecimento e familiaridade com referencial teórico. Ambos os grupos indicam conceituação confusa, notadamente para os termos oficiais, superdotação e altas-habilidades; a maior carga de rejeição e exploração na mídia é alocada a superdotação. Os conceitos alta capacidade, alto desempenho e dotação são definidos em consonância com o referencial básico, que diferencia capacidade natural de capacidade adquirida; Talento reflete a ambiguidade encontrada na área, referindo-se, ao mesmo tempo, a capacidade natural e capacidade adquirida.

Políticas feministas do aborto

Os debates e as ações feministas em prol da liberalização do aborto no Brasil foram marcados por avanços, recuos e, sobretudo, por inúmeras negociações políticas. da omissão da palavra aborto, em meados dos anos 70, à opção política pela descriminalização e pela realização dos casos previstos por lei, observa-se uma vocação política do feminismo brasileiro para a negociação. Conclui-se que essas negociações tiveram mais êxito em nível político do que social, pois não lograram alcançar e sensibilizar camadas mais amplas da população.

A terminologia relativa à hanseníase

A padronização internacional de doenças é um processo complexo que necessita de uma equipe especializada. Esta comunicação visa a esclarecer e sugerir correções de um provável equívoco na tradução, para o português da CID-10, do código A30, no qual os termos borderline e dimorfo são utilizados como subcategorias distintas e não como sinônimos, assim como substituir a designação lepromatosa por virchoviana pois, no Brasil, o vocábulo lepra foi abolido dos textos oficiais, por uma lei federal em 1995.

THE FAMILY COMPSOPOGONACEAE (RHODOPHYTA) IN BRAZIL

A taxonomic revision of the family Compsopogonaceae in Brazil was carried out, resulting in the recognition of a single genus (Compsopogon) with two species (C. coeruleus and C. leptoclados). For both species the following information was provided: a) nomenclatural type; b) type locality; c) description (with illustrations); d) diagnostic features; e) world distribution; f) distribution in Brazil (with map); g) habitat, associated species and seasonality; h) remarks, including discussion of taxonomic and/or nomenclatural problems and comparison with previous reports based on Brazilian and foreign material. Currently accepted diagnostic criteria for genera and species within Compsopogonaceae are critically analysed. The circumscription of Compsopogon and Compsopogonopsis are evaluated and the single genus Compsopogon is recognized in the family.

Relation between speaking space of the /s/ sound and freeway space in dentate and edentate subjects.

The purpose of this study is to assess the relation between the speaking space of the /s/ sound and the freeway space in two subject groups. One group had natural dentition (Group I, n = 61) and the other comprised complete denture wearers (Group II, n = 33). The analysis was done by means of a jaw-tracking device (K6-I Diagnostic System, Myotronics Research Inc., Seattle, WA, USA). Freeway space was determined by asking the subjects to occlude from the postural rest position. Speaking space of /s/ was measured during the pronunciation of the word seis and comprised the mean distance from the /s/ speaking position to maximal intercuspation. A weak correlation was found between the speaking space of /s/ and the freeway space in Group I (r = 0.41, p < 0.01), but in Group II, the correlation was stronger (r = 0.75, p < 0.01). The speaking space of /s/ and freeway space were different in Group I, but statistically similar in Group II (paired t-test, alpha = 0.05). It can be suggested that anatomic changes following prosthetic procedures caused a functional adaptation which resulted in more similar values for the speaking space of /s/ and the freeway space.

The disintegration of patriarchal system expressed by the bourgeois novel's crisis

The Modern Era is marked by a great revolution in the economic, political and social structure, mainly on account of the sprouting of bourgeoisie, which brings the Bourgeois Novel as a new way to express their feelings and conflicts. In this article, one of the bourgeois characteristics, the patriarchal system, will be discussed. However, the focus will be on its dissolution, which is one evidence of the bourgeois novel's crisis. The word 'crisis' can also be understood as transformation. Thus, in order to illustrate this literary revolution undertaken by women, this article analyses To The Lighthouse, by Virginia Woolf. In this novel, it seems that nothing important happens. However the Stream of Consciousness narrative, with the predominance of Indirect Interior Monologue, psychological time and intertextualities, allows for meaning construal grounded in the dichotomy life/dead. The disintegration of the patriarchal structure is seen from the perspective of power relation between the head of the family and his wife. In addition, a reflection on the role of the woman as an artist is carried out.
