Sobre projetos, palavras e imagens: relacionando textos e desenhos nos trabalhos finais de graduação em arquitetura e urbanismo

This research continues the current debate about the role of the images and the words in the architectural design persuasion, where we emphasize the increasing valuation of written documents (FORTY, 2004; MARKUS; CAMERON, 2002), the seduction for the graphical representation (DURAND, 2003) and the rhetorical effects of the graphical and textual resources (TOSTRUP, 1999). Based on these quarrels, we look for verify in the graduate final projects the relation between the design texts and images. From the PROJEDATA, database of the PROJETAR research group (UFRN), we selected the final projects of two brazilians universities, UFRN and USP, that in a first analysis, they had shown as ideal types of two distinct design presentation models, respectively: texts and drawings in separated documents, or combined in an only support. Based on Markus explanation about the function and the content of the texts, on the Durand perspective with regard to graphical representation uses and on Tostrup point of view concerning the rhetorical potential of texts and drawings, we analyze, in a set of 25 projects, how the students relate the textual and imagetical speeches. For this, we related the focus of each speech, in order to verify the possible coherence between both. We conclude that in the model of USP final project the coherence between the texts and the drawings is clearer than in the model adopted in UFRN

Evocando o cachimbo de Magritte: das dotações, políticas de pessoal e discursos de acessibilidade

Uma análise que interliga a questão das dotações (da diferença com os rácios, dos métodos e dos fatores a ter em conta) com a gestão de recursos humanos (a necessidade de um plano estratégico de recursos humanos na saúde) e os discursos de acessibilidade e acesso universal a cuidados de enfermagem. Três prismas que convergem na necessidade de se prestar atenção e ter em conta, portanto a recentrar nas questões da equidade e da responsabilidade.

Conhecimento e uso do dialeto/falar madeirense dos jovens em escolarização da Região Autónoma da Madeira : análise de enunciados dialetais : léxico

Este trabalho de investigação insere-se no âmbito da sociolinguística e debruça-se sobre a perceção quanto à variação dialetal do Arquipélago da Madeira, que os jovens em escolarização da Região Autónoma da Madeira detêm face a alguns traços particulares do léxico. Neste sentido, o corpus de trabalho baseou-se nos dados recolhidos em inquéritos por questionário sobre o léxico, realizados a uma amostra de 40 alunos naturais do arquipélago, a frequentarem o 3º Ciclo do Ensino Básico e distribuídos por dez alunos em quatros escolas localizadas: a norte (Santana-São Jorge) e a sul (Funchal e Câmara de Lobos) da ilha da Madeira e na ilha do Porto Santo. Para podermos, efetivamente, determinar quais as influências extralinguísticas ou quais as variáveis socioculturais responsáveis pelo conhecimento e uso dos dialetos, foi também importante analisar alguns fatores de ordem social, tais como, o meio familiar, a idade, o nível de escolaridade dos alunos, a naturalidade e o contacto destes com os meios urbano vs rural. Com efeito, e com base nos instrumentos de análise recolhidos, este estudo mostra-nos que os jovens madeirenses em escolarização ainda evidenciam um interesse em usar e manter a sua identidade dialetal, numa dinâmica intergeracional, dado que os mesmos consideram importante não deixar desaparecer um legado linguístico que tem sido herdado pelos seus antepassados. Contudo, constatamos que o domínio dos dialetos madeirenses juntos destes jovens começa a estar um pouco ausente nas suas conversas do quotidiano, principalmente quanto contactam com falantes fora do arquipélago, moldando os seus discursos em norma/padrão, por assim entenderem tratar-se de uma forma comunicacional, dotada de mais prestígio social. Em contrapartida, verificámos que o meio familiar e o meio rural contribuem, portanto, para um uso mais frequente da variação dialetal, provando-se esta realidade, sobretudo, nos jovens em escolarização residentes nos concelhos a norte da ilha da Madeira e na ilha do Porto Santo. Por considerarmos importante novas investigações, sobretudo pela temática que aqui foi abordada, consideramos que seria deveras pertinente surgirem futuros estudos. Assim, estes poderão explicar a origem do extenso léxico dos dialetos madeirenses e no caso particular da variação dialetal na pequena ilha do Porto Santo, considerando-se, para o efeito, também a vertente sociolinguística.

DESENVOLVIMENTO TERRITORIAL E SUSTENTABILIDADE NO SEMI-ÁRIDO DA BAHIA - BRASIL: ANÁLISE DAS POLÍTICAS EDUCACIONAIS E DO ENSINO AGRÍCOLA NO TERRITÓRIO DE IRECÊ

O trabalho buscou analisar a relação desenvolvimento sustentável, território e políticas educacionais. Discutiu-se a territorialidade da escola agrotécnica de Irecê, procurando compreender sua contribuição para a promoção do desenvolvimento e da sustentabilidade do território. Analisaram-se os pressupostos estruturais que deram sustentação e direcionamento ao desenvolvimento do ensino agrotécnico no Brasil e seus reflexos às racionalidades da Política Estadual de Educação para tal modalidade no Estado da Bahia. Evidenciou-se a influência dos discursos ambientalistas global e nacional à elaboração das Diretrizes Curriculares do Ensino Agrícola no Estado da Bahia na década de 1990 e os desafios, contradições e conflitos no processo de materialização dessas orientações curriculares. Desta forma, através da abordagem territorial, verificaram-se os reflexos de tais racionalidades políticas e institucionais para o território. A análise esteve calcada na dialética materialista e histórica, cuja abordagem teve um cunho qualitativo. Ficou evidente a necessidade de: articulação mais direta entre a escola agrotécnica e as políticas de desenvolvimento territorial; repensar a relação escola-comunidade, a fim de abarcar o meio rural como elemento pedagógico; e que a territorialidade da escola agrotécnica esteve historicamente atrelada a racionalização do capital do campo, cujo espaço vivido permitiu a estruturação de algumas práticas alternativas.

Aplicação do escore MELD em pacientes submetidos a transplante de fígado: análise retrospectiva da sobrevida e dos fatores preditivos a curto e longo prazo

BACKGROUND: The model for end-stage liver disease (MELD) was developed to predict short-term mortality in patients with cirrhosis. There are few reports studying the correlation between MELD and long-term posttransplantation survival. AIM: To assess the value of pretransplant MELD in the prediction of posttransplant survival. METHODS: The adult patients (age >18 years) who underwent liver transplantation were examined in a retrospective longitudinal cohort of patients, through the prospective data base. We excluded acute liver failure, retransplantation and reduced or split-livers. The liver donors were evaluated according to: age, sex, weight, creatinine, bilirubin, sodium, aspartate aminotransferase, personal antecedents, brain death cause, steatosis, expanded criteria donor number and index donor risk. The recipients' data were: sex, age, weight, chronic hepatic disease, Child-Turcotte-Pugh points, pretransplant and initial MELD score, pretransplant creatinine clearance, sodium, cold and warm ischemia times, hospital length of stay, blood requirements, and alanine aminotransferase (ALT >1,000 UI/L = liver dysfunction). The Kaplan-Meier method with the log-rank test was used for the univariable analyses of posttransplant patient survival. For the multivariable analyses the Cox proportional hazard regression method with the stepwise procedure was used with stratifying sodium and MELD as variables. ROC curve was used to define area under the curve for MELD and Child-Turcotte-Pugh. RESULTS: A total of 232 patients with 10 years follow up were available. The MELD cutoff was 20 and Child-Turcotte-Pugh cutoff was 11.5. For MELD score > 20, the risk factors for death were: red cell requirements, liver dysfunction and donor's sodium. For the patients with hyponatremia the risk factors were: negative delta-MELD score, red cell requirements, liver dysfunction and donor's sodium. The regression univariated analyses came up with the following risk factors for death: score MELD > 25, blood requirements, recipient creatinine clearance pretransplant and age donor >50. After stepwise analyses, only red cell requirement was predictive. Patients with MELD score < 25 had a 68.86%, 50,44% and 41,50% chance for 1, 5 and 10-year survival and > 25 were 39.13%, 29.81% and 22.36% respectively. Patients without hyponatremia were 65.16%, 50.28% and 41,98% and with hyponatremia 44.44%, 34.28% and 28.57% respectively. Patients with IDR > 1.7 showed 53.7%, 27.71% and 13.85% and index donor risk <1.7 was 63.62%, 51.4% and 44.08%, respectively. Age donor > 50 years showed 38.4%, 26.21% and 13.1% and age donor <50 years showed 65.58%, 26.21% and 13.1%. Association with delta-MELD score did not show any significant difference. Expanded criteria donors were associated with primary non-function and severe liver dysfunction. Predictive factors for death were blood requirements, hyponatremia, liver dysfunction and donor's sodium. CONCLUSION: In conclusion MELD over 25, recipient's hyponatremia, blood requirements, donor's sodium were associated with poor survival.

Conseqüências da análise incorreta de experimentos blocados

Errors are always present in experimental measurements so, it is important to identify them and understand how they affect the results of experiments. Statistics suggest that the execution of experiments should follow random order, but unfortunately the complete randomization of experiments is not always viable for practical reasons. One possible simplification is blocked experiments within which the levels of certain factors are maintained fixed while the levels of others are randomized. However this has a cost. Although the experimental part is simplified, the statistical analysis becomes more complex.

O estado da arte da cromatografia associada à espectrometria de massas acoplada à espectrometria de massas na análise de compostos tóxicos em alimentos

Chromatography combined with several different detection systems is one of the more used and better performing analytical tools. Chromatography with tandem mass spectrometric detection gives highly selective and sensitive analyses and permits obtaining structural information about the analites and about their molar masses. Due to these characteristics, this analytical technique is very efficient when used to detect substances at trace levels in complex matrices. In this paper we review instrumental and technical aspects of chromatography-tandem mass spectrometry and the state of the art of the technique as it is applied to analysis of toxic substances in food.

The objective of this research was to evaluate the influence of climatization investment in the milk production process and analyze the economical aspect of this investment. There were used 470 high productive dairy cows with genetic and morphologic homogeneous characteristics, and analyzed in two similar periods. Investment calculations were done using Excell®. The results were satisfactory and the invested capital was proved to return to the producer in a short term, 57 days.

Modelo de programação quadrática para análise da movimentação logística e comercialização da soja brasileira

The purpose of this work was to analyze the logistical distribution of Brazilian soybean by applying a quadratic programming to a spatial equilibrium model. The soybean transportation system is an important part of the soybean complex in Brazil, since the major part of the costs of this commodity derives from the transportation costs. Therefore, the optimization of this part of the process is essential to a better competitiveness of the Brazilian soybean in the international market. The Brazilian soybean complex have been increasing its agricultural share in the total of the exportation value in the last ten years, but due to other countries' investments the Brazilian exportations cannot be only focused on increasing its production but it still have to be more efficient. This way, a model was reached which can project new frames by switching the transportation costs and conduce the policy makers to new investments in the sector.

Análise de aspectos socioeconômicos e tecnológicos da agropecuária na Bacia Hidrográfica do Rio Mogi Guaçu

Currently, owing to the occurrence of environmental problems, along with the need of environmental preservation, both the territory management of Hydrographic Basin and the conservation of natural resources have proven to have remarkable importance. Thus, the mean goal of the research is to raise and scrutinize social-economic and technologic data from the Mogi Guaçu River Hydrographic Basin (São Paulo, Brazil). The aim is to group municipalities with similar characteristics regarding the collected data, which may direct joint actions in the Hydrographic Basin Management. There were used both the methods of factorial analysis and automatic hierarchical classifications. Additionally, there is going to be applied a Geographical Information System to represent the outcomes of the methods aforementioned, through the evolvement of a geo-referenced database, which will allow the obtainment of information categorically distributed including theme maps of interest. The main characteristics adopted to group the municipalities were: agricultural area, sugar cane production, small farms, animal production, number of agriculture machinery and equipments and agricultural income. The methodology adopted in the Mogi Guaçu River Hydrographic Basin will be analyzed vis-à-vis its appropriateness on basin management, as well as the possibility of assisting the studies on behalf of the São Paulo Hydrographic Basin groups, to regional development.
