Produção de narrativas escritas no ensino fundamental: estudo de casos

This paper focuses on the construction of the narrative for elementary school students, searching to identify strategies they employed in the production of narrative texts representative of miniconto genre. Therefore, we take a sample forty texts produced by students of 6 and 9 years of basic education, twenty in the 6th year students (ten public school and ten private school) and twenty students in 9th grade (distributed similarly between public education and private). In general, we aim to understand the mechanisms by which producers build their narratives, as well as providing input for analysis of textual production of this genre. This research is based on Functional-Linguistic assumptions of the American side, inspired by Givón (2001), Thompson (2005), Hopper (1987), Bybee (2010), Traugott (2003), Martelotta (2008), Furtado da Cunha (2011), among others. In addition, from the theoretical framework presented by Labov (1972) about the narrative, coupled with Batoréo contribution (1998), we observed the recurring elements in the structure of narratives under study: abstract, orientation, complication, resolution, evaluation and coda. Also approached, but that in a complementary way, the notion of gender presented in Marcuschi (2002). This is a research quantitative and qualitative, with descriptive and analytical-interpretive bias. In corpus analysis, we consider the following categories: gender discourse miniconto; compositional structure of the narrative; informativeness (discursive progression, thematic coherence and narrative, topical-referential distribution); informative relevance (figure / ground). At the end of the work, our initial hypothesis of the better performance of students in 9th grade, compared to 6, and the particular context of education in relation to the public context, not confirmed, since, in the comparative study revealed that the groups have similar performance as the construction of the narrative, making use of the same strategies in its construction.

Efeitos da aplicação tópica do mel de melipona subnitida em feridas infectadas de ratos

Avaliar efeitos do uso tópico do mel da abelha silvestre Melipona subnitida na evolução de feridas infectadas de pele. Método: Ratos Wistar foram distribuídos aleatoriamente em grupos de 6, anestesiados com tiopental sódico 20mg/Kg IP e cetamina 30mg/Kg IM e submetidos a exérese de segmento de 1 cm2 de pele total do dorso. Os ratos do grupo C (não infectado) foram tratados com solução salina sobre a ferida diariamente e no grupo MEL (não infectado) as feridas foram tratadas com mel uma vez por dia. Nos grupos C/I e MEL/I as feridas foram inoculadas com solução polimicrobiana. Culturas foram feitas 24 horas após. Caracterizada a infecção, as feridas foram tratadas com solução salina e mel, respectivamente. No terceiro dia de tratamento foi feita nova cultura. Após epitelização foi contado o tempo de cicatrização e as feridas foram biopsiadas para histopatologia e dosagem de TNF-a, IL-1b e IL-6 no tecido. Resultados: O tempo médio de cicatrização do grupo MEL/I foi menor que nos demais grupos(P<0,05). Verificou-se que a densidade de colágeno, leucócitos, fibroblastos e dosagem de citocinas (especialmente TNF) foi maior no grupo infectado e tratado com mel que nos demais grupos. Houve significante redução de bactérias Gram-negativas e positivas nas feridas após o tratamento com mel. Conclusão: O uso tópico de mel de Melipona subnitida em feridas infectadas da pele de ratos estimulou a resposta imunológica, reduziu a infecção e o tempo de cicatrização

Análise conceitual e pensamento crítico: uma relação complementar na enfermagem

O propósito deste trabalho é mostrar a relação entre o processo de análise conceitual e as habilidades de pensamento crítico na enfermagem. Utilizando uma abordagem de ensaio discursivo, argumenta-se que a técnica de análise conceitual promove a criticidade em alunos de enfermagem. Os passos da atividade de análise são examinados quanto às operações cognitivas neles inseridas e que representam habilidades de raciocínio crítico. Reflete-se sobre a análise conceitual como atividade didática na promoção do pensamento crítico em uma experiência com alunos de graduação. Conclui-se que os dois processos se complementam no repensar e no enfrentamento de desafios na enfermagem

Diagnóstico, estadiamento e tratamento cirúrgico do adenocarcinoma de pâncreas

O adenocarcinoma pancreático é um dos tumores sólidos de pior prognóstico, sendo o tratamento cirúrgico o único potencialmente curativo. Na grande maioria dos pacientes o tumor é diagnosticado em fase avançada, comumente na presença de doença metastática. A introdução de modernos métodos diagnósticos associados ao aperfeiçoamento dos já existentes tem gerado controvérsia quanto à melhor maneira de se estabelecer o diagnóstico e estadiamento do tumor. Da mesma forma, o papel da cirurgia na paliação e aspectos técnicos da ressecção de lesões localizadas estão longe de alcançarem consenso na prática. Método - Revisão da literatura sobre os aspectos controversos relacionados ao tema e um algoritmo para a abordagem dos pacientes com suspeita de tumor de pâncreas são apresentados. Foram utilizados os descritores: “adenocarcinoma” e “pâncreas” para pesquisa no PubMed (www.pubmed.com) e na Bireme (www.bireme.br) e a seguir selecionadas as publicações pertinentes a cada tópico escolhido com atenção especial para metanálises, estudos clínicos controlados, revisões sitemáticas e ainda publicações de grandes centros especializados em doenças pancreáticas. Conclusões - Na suspeita de adenocarcinoma de pâncreas é possível realizar estadiamento muito próximo do real sem a necessidade da exploração cirúrgica sistemática em virtude da disponibilidade na prática de exames modernos e eficientes. Isso permite que paliação menos invasiva seja praticada na maioria dos pacientes com lesões avançadas e incuráveis. Nos em que a cura é possível, a operação deve ser realizada objetivando-se, essencialmente, a remoção da lesão com margens livres e com aceitáveis índices de morbi-mortalidade

Política de promoção da exportação : um olhar sobre a evolução da cultura de melão do Rio Grande do Norte

Some sectors in Brazil are earning notoriety in the international market, configuring itself in dynamic areas for the Country. The most typical case is the agribusiness. Rio Grande do Norte state has important role, because 90% of the output of the melon exported by Brazil is produced at Assu/Mossoró. The present work planned to verify the evolution of the culture of the melon produced at Assu/Mossoró area, from 1990 to 2003. Through descriptive research, utilizing the case study and documentary analysis of secondary data this work showed the evolution of the area reaped of melon in the pole Assu/Mossoró, the quantity produced of melon and of the value of the output of the melon between 1990 and 2003. The research verified that all of the factors studied show growth during the analyzed period, showing up the importance of the agribusiness for the region. However the analysis shows the vulnerability of the sector concerning external macroeconomics factors, such as the exchange rates. Showing the importance and/or dependence of the producers for public actions to development of the culture, that might be on areas like infrastructure, economics or taxes

Modelo de decisão multicritério para seleções interciclo das universidades novas: estudo na Universidade Federal do Rio Grande do Norte

The discussions wherein develop proposals for university reform in Brazil include, among other things, the conception of the university titled "New University", whose structural origin comes from the bill of higher education reform and unification of the foundations of education European upper (Bologna process). At its core, the Bologna process has imposed a series of transformations, among which, the promotion of mobility, as a stimulus to interinstitutional cooperation to enable an better and bigger qualification of the students. Nevertheless, what we see is that this point is one of the main points made flawed by Brazilian institutions that have adopted this model of higher education. An example is the Bachelor of Science and Technology - BC&T, Federal University of Rio Grande do Norte - UFRN, where there are problems of the internal order, represented by the problem of the reusing of the disciplines, such also of external order, in cases of transfers interinstitutional. Because of this, and knowing that this is a typical problem in which multiple criteria are involved, the aim of this study is to propose a multicriteria model for selection of interciclo of the BC&T of the UFRN which addresses the issue of mobility. For this, this study was of exploratory and study case nature, use as tools of data collection, the bibliographic and documentary research, as well as semi-structured interviews. For the elaboration of the model, were used the five phases most commonly used in the modeling of problems in operational research in a sample of 91 students of BC&T. As a result, we obtained a model that addresses the issue of internal and external mobility of the school and that, moreover, was also more robust and fair than the current model of BC&T and also what is used in other courses of the UFRN, taking into consideration the expected results by the decision makers

Papel da proteína de reparo XPC na regulação das proteínas de reparo APE1, OGG1 e PARP-1 em células humanas e de camundongos

studies using UV as a source of DNA damage. However, even though unrepaired UV-induced DNA damages are related to mutagenesis, cell death and tumorigenesis, they do not explain phenotypes such as neurodegeneration and internal tumors observed in patients with syndromes like Xeroderma Pigmentosum (XP) and Cockayne Syndrome (CS) that are associated with NER deficiency. Recent evidences point to a role of NER in the repair of 8-oxodG, a typical substrate of Base Excision Repair (BER). Since deficiencies in BER result in genomic instability, neurodegenerative diseases and cancer, it was investigated in this research the impact of XPC deficiency on BER functions in human cells. It was analyzed both the expression and the cellular localization of APE1, OGG1 e PARP-1, the mainly BER enzymes, in different NER-deficient human fibroblasts. The endogenous levels of these enzymes are reduced in XPC deficient cells. Surprisingly, XP-C fibroblasts were more resistant to oxidative agents than the other NER deficient fibroblasts, despite presenting the highest of 8-oxodG. Furthermore, subtle changes in the nuclear and mitochondrial localization of APE1 were detected in XP-C fibroblasts. To confirm the impact of XPC deficiency in the regulation of APE1 and OGG1 expression and activity, we constructed a XPC-complemented cell line. Although the XPC complementation was only partial, we found that XPC-complemented cells presented increased levels of OGG1 than XPC-deficient cells. The extracts from XPC-complemented cells also presented an elevated OGG1 enzimatic activity. However, it was not observed changes in APE1 expression and activity in the XPCcomplemented cells. In addition, we found that full-length APE1 (37 kDa) and OGG1- α are in the mitochondria of XPC-deficient fibroblasts and XPC-complemented fibroblasts before and after induction of oxidative stress. On the other hand, the expression of APE1 and PARP-1 are not altered in brain and liver of XPC knockout mice. However, XPC deficiency changed the APE1 localization in hypoccampus and hypothalamus. We also observed a physical interaction between XPC and APE1 proteins in human cells. In conclusion, the data suggest that XPC protein has a role in the regulation of OGG1 expression and activity in human cells and is involved mainly in the regulation of APE1 localization in mice. Aditionally, the response of NER deficient cells under oxidative stress may not be only associated to the NER deficiency per se, but it may include the new functions of NER enzymes in regulation of expression and cell localization of BER proteins

Estudo comparativo de pás para aerogeradores de grande porte fabricadas em materiais compósitos reforçadas com fibra de carbono ou fibra de vidro

The research and development of wind turbine blades are essential to keep pace with worldwide growth in the renewable energy sector. Although currently blades are typically produced using glass fiber reinforced composite materials, the tendency for larger size blades, particularly for offshore applications, has increased the interest on carbon fiber reinforced composites because of the potential for increased stiffness and weight reduction. In this study a model of blade designed for large generators (5 MW) was studied on a small scale. A numerical simulation was performed to determine the aerodynamic loading using a Computational Fluid Dynamics (CFD) software. Two blades were then designed and manufactured using epoxy matrix composites: one reinforced with glass fibers and the other with carbon fibers. For the structural calculations, maximum stress failure criterion was adopted. The blades were manufactured by Vacuum Assisted Resin Transfer Molding (VARTM), typical for this type of component. A weight comparison of the two blades was performed and the weight of the carbon fiber blade was approximately 45% of the weight of the fiberglass reinforced blade. Static bending tests were carried out on the blades for various percentages of the design load and deflections measurements were compared with the values obtained from finite element simulations. A good agreement was observed between the measured and calculated deflections. In summary, the results of this study confirm that the low density combined with high mechanical properties of carbon fibers are particularly attractive for the production of large size wind turbine blades

Ensaio clínico duplo-cego controlado e randômico, comparando a eficácia da Clofazimina com a Cloroquina, no tratamento das lesões cutâneas do Lúpus Eritematoso Sistêmico

PURPOSE: To evaluate the capacity of clofazimine (CFZ) to control cutaneous activity of systemic lupus erythematosus (SLE), compared with chloroquine diphosphate (CDP). METHODS: A prospective, randomized, controlled, double blind clinical trial was carried out in thirty-three patients with SLE and cutaneous lesions (malar rash and/or discoid lupus and/or subacute cutaneous lupus), after approval by the respective Ethics Committee. Sixteen patients received clofazimine - 100mg/day (CFZ group) and 17 received chloroquine diphosphate - 250mg/day (CDP group), during six months. Both groups applied broad-spectrum sunscreens twice a day. The dose of prednisone was kept stable during the study. Cutaneous lesions were evaluated by 2 blinded observers and photographed at baseline and at months 1, 2, 4 and 6. RESULTS: Thirty-three patients began and 27 completed the 6 months of treatment. The groups were homogeneous and comparable in terms of demographic and clinical characteristics. Five CFZ-patients and one CDP-patients dropped out due to severe flare of disease requiring other treatment. At the end of the study, 12 CFZ-patients (75%) and 14 CDP-patients (82,4%) presented complete or near-complete remission of skin lesions; intention-to-treat analysis showed no significant difference in the response rates between groups. Side effects in both groups were frequent, but patients didn t have to discontinue the drugs. CONCLUSIONS: Clofazimine and chloroquine were effective in controlling cutaneous lesions in SLE patients

Acordos internacionais sobre a produção compartilhada de recursos naturais: a unitização interestatal na área do petróleo e gás sob o enfoque constitucional brasileiro

The apportionment of natural resources between sovereign States is a subject that relates many aspects of International law, as long as Constitutional Law, at the execution and application phases of international treaties that regulates the exploration of common goods. In this sense, because of their natural characteristics that creates an environment of constant migration and fixation in transboundary regions, terrestrial or maritime, the petroleum and the natural gas bound a complex juridical apparatus that can control the sovereign rights involved. This research is aim at accomplishing a study concerning the international agreements that enable the non-unilateral action, specifically the unitization treaties between sovereign States, as a manner to resolve situations related to the individualization of oil and/or gas reservoirs that go across their national borders. These agreements will be analyzed considering the international public law sources theory, bearing in mind yet the already existed experiences in this sense, not disregarding the way that this fact could affect Brazil. It will begin with an historical incursion over the unitization institute, covering its main characteristics and its formation and execution procedures, and finally it will address the Brazilian legal system and the comparative law threats the institute. The clauses of these relevant agreements will be analyzed in details, concerning its particularities and its contents. Because these agreements are international obligatory rules of law, it is indispensable that they are considered under the auspices of the international law system, focusing their nature and the subjects of international law and establishing them as sources of the international law, analyzing them, then, as international rules and the applicable law to these juridical relations, the conventional established, the consolidated international custom and the applicable International Law principles, appearing the State s responsibility as an important subject for the verification of the acts lawful practiced by States. The analysis of the apportionment of these natural resources ends with the individualization of possible exploitable marine oil fields located between the exclusive economic zone and the continental platform ends and the region administrated by the International Seabed Authority. At last, the Brazilian constitutional system appears as the mechanism of integration, application and execution of the international unitization agreements in Brazil, detaching the format and the proceedings that the international treaties take to acquire validity at the national legal system, passing through the treaties interpretation and the applicable constitutional principles, coming to its application in Brazil, considering the existing constitutional peculiarities and the role played by the National Agency of Petroleum, Natural Gas and bio-fuel ANP

A alteração do tipo penal de adulteração de combustíveis: reflexo da constitucionalização do direito penal no mercado de combustíveis

The neoconstitutionalism led to a process of ethical revaluation of the normative systems and the process of constitutionalization of the many fields of law. This study examines the consequences of this process in criminal law, so important a Law field for the protection of the most valuable assets by the society, including the fundamental guarantees, thus emphasizing the necessity of protection of the collective and individual rights, which are guided by the observance of the defendants individual rights in the course of criminal proceedings and the search for the best efficiency of penal protection, according to the corollaries of defense against the state (prohibition of the excess or Übermassverbot) and the provision of rights by the state (prohibition of insufficient protection or Untermassverbot). The offense of fuel adulteration is taken as an object of study, since it is a vital market to a nation dependent of people and good s movement for their living, driven by fossil and biofuels. Such a crime affects essential legal interests to the development of society, interests such as the environment, consumer relations and economic order, particularly the principle of free competition. This paper seeks to analyze the need of a greater efficiency of this particular criminal protection, once concluded the conduct harm and social fear as a consequence by it as growing, and therefore having its former crime type, engraved in Article 1 of Law No. 8.176/1991, rewritten in compliance with the criminal law s principle of legality. Thus, the reformation proposals and legislative creation involving this crime were observed, with emphasis on the bill No. 2498/2003, which keeps it as blank heterogeneous criminal norm, kind of penal normative whose constitutionality is raised, including the forethought of criminal responsibility in the perpetrating of the offense as culpable and subsequently increasing the applicable minimum penalty, as well as the inclusion of new activities in the typical nucleus
