O presente trabalho realiza um estudo referente à Geometria Tridimensional, no que tange a sua metodologia apresentada nos livros didáticos de Matemática. Esse instrumento tem passado por um processo de avaliação mais rigoroso nas últimas décadas pelos órgãos governamentais para a promoção do livro com qualidade o que é importante, porém uma análise crítica de seus conteúdos é essencial para que esse instrumento torne-se adequado a cada realidade e um aliado no planejamento do educador no processo de ensino e aprendizagem da Geometria. Essa disciplina é considerada por vários autores e especialista da educação como um conhecimento muito pertinente para a formação integral do aluno, ao proporcionar o desenvolvimento do raciocínio visual, espacial e lógico, abrangendo também a formação cultural e profissional. Nesse sentido, considerando a importância da escolha de um livro adequado e coerente para a qualidade desse ensino, objetivouse com esse estudo realizar uma análise e reflexão sobre os conteúdos da Geometria Tridimensional apresentada em dois livros didáticos de matemática do 5º ano do ensino fundamental submetidos aos critérios eliminatórios do Programa Nacional do Livro Didático - PNLD (2013) e aprovado pelo Ministério da Educação. Mediante levantamento bibliográfico da literatura pertinente e análise de documentos oficiais foi possível verificar que os mesmos apresentaram progressos em alguns aspectos atendendo de forma parcial as propostas atuais para esse ensino demonstrando que ainda precisam evoluir

The use of computers in dental clinics has brought many benefits to dentist, helping them in various technical, administrative and legal. This study aimed to verify whether dentist, students of the post-graduate course in Orthodontics and Implantodontia of the Brazilian Association of Dentistry (ABO), regional Araçatuba-SP, using computers and digital documentation in clinical practice. They were invited to participate in the study all 60 students enrolled in courses of Orthodontics and Implantodontia of those institutions, in the year 2007 and those who consented (n = 52) answered a questionnaire containing questions open and closed on the subject . As the profile of the participants, 64.5% are male, 51.9% are between 30-39 years of age and 48.1% completed the graduation in the 90th. A 69.3% said they didn't receive any notion of computing during graduation and 67.3% use the computer in the office, mainly for management of the same (34.3%). Regarding the use of electronic record 55.8% reported using this technology, while 44.2% denied. 32.7% do not believe that electronic records that can serve as proof of judicial and 35.7% believe that the electronic records should be archived for 20 years. It follows that most professionals use the computer in the office and also the digital records, but does not feel secure about the legal validity of such documents, unknown, including the appropriate time of its filing.

A presente invenção descreve um arcabouço (scaffold) tridimensional biodegradável de fibrina, formado por uma serinoprotease extraída a partir de veneno de serpente, um crioprecipitado rico em fibrinogênio extraído de bubalinos, o diluente cloreto de cálcio e uma solução de uma população de células tronco. O arcabouço é apropriado para suportar uma população de 106 células por mL de fibrina por um período prolongado de tempo, em que as células tronco são mesenquimais, de tecido umbilical e células tronco mononucleares. A invenção descreve, ainda, o processo de obtenção do arcabouço, cujos componentes são providos separadamente e polimerizam-se in situ após mistura. O arcabouço descrito apresenta inúmeras aplicações médicas, podendo aumentar a vascularização, a quimiotaxia celular, a regeneração nervosa e/ou a cicatrização de feridas no local da administração. Devido à sua origem animal, não há o risco de transmitir doenças infecciosas.

The present work is determined to analyse trigonometry problem solving with the help of CabriGéomètre II software from the perspective of two axes of mathematics teaching which are: the concept formation in Klausmeier and Goodwin´s perspective(1977) and problem solving according to Sternberg’s conception(2000). With such an approach traces of a more significant learning may be found , which according to Ausubel(1980) enables the adoption of better teaching and learning practices.

Origami folds and kirigami cuts merged in an oriental technique called Origamic Architecture (or 3D kirigami) that has intrinsic relationships with geometry as well as these paper arts. Despite its potential, it is not very used as a didactic resource because of the lack of parameters in its construction. There are many studies about programs development and computational language to help the design of pop-up structures, as origamic architecture is also known. However, there are few studies concerning the study of positioning the lines and creases, which is essential in the process of creating a 3D kirigami design, especially in the development of spatial perception of the figure. Limited to the 90o open type models, this article is about the establishment of some initial guidelines for design of an origamic architecture through visual elements as point, line and shape. It is presented some basic models to illustrate the constructive parameters detected as well as some models elaborated by the author, showing the viability of the guidelines established.

This study aims to develop innovative proposals for production agriculture management and plans to build a participatory model, through the digital inclusion of members of the family farm gathered in a cooperative venture seeking to establish new environmental management efficiency for household production. The first part of the hypothesis assumes that a major obstacle to the insertion of small family farms into the markets is skilled labor, human capital. A training model has been developed for traceability and tracking activities on family farms, based on the atemoya culture. The second hypothesis predicts that it is possible to create a model that is scientifically supported by widely accepted rules derived from GlobalGAP standard certification, a global benchmark for good agricultural practices. Using these rules the model seeks to achieve the traceability of agricultural products and operations from the preservation of identity information within the production chain. The results obtained by the computerized system confirmed the presented hypotheses by demonstrating that technological innovation through intensive communication and information technologies education as well as other associated forms are important drivers of regional development, especially if implemented through a digital inclusion project using the state program Infocentros Access São Paulo.
