Furthered mainly by new technologies, the expansion of distance education has created a demand for tools and methodologies to enhance teaching techniques based on proven pedagogical theories. Such methodologies must also be applied in the so-called Virtual Learning Environments. The aim of this work is to present a planning methodology based on known pedagogical theories which contributes to the incorporation of assessment in the process of teaching and learning. With this in mind, the pertinent literature was reviewed in order to identify the key pedagogical concepts needed to the definition of this methodology and a descriptive approach was used to establish current relations between this conceptual framework and distance education. As a result of this procedure, the Contents Map and the Dependence Map were specified and implemented, two teaching tools that promote the planning of a course by taking into account assessment still in this early stage. Inserted on Moodle, the developed tools were tested in a course of distance learning for practical observation of the involved concepts. It could be verified that the methodology proposed by the above-mentioned tools is in fact helpful in course planning and in strengthening educational assessment, placing the student as central element in the process of teaching and learning

The increasing of the number of attacks in the computer networks has been treated with the increment of the resources that are applied directly in the active routers equip-ments of these networks. In this context, the firewalls had been consolidated as essential elements in the input and output control process of packets in a network. With the advent of intrusion detectors systems (IDS), efforts have been done in the direction to incorporate packets filtering based in standards of traditional firewalls. This integration incorporates the IDS functions (as filtering based on signatures, until then a passive element) with the already existing functions in firewall. In opposite of the efficiency due this incorporation in the blockage of signature known attacks, the filtering in the application level provokes a natural retard in the analyzed packets, and it can reduce the machine performance to filter the others packets because of machine resources demand by this level of filtering. This work presents models of treatment for this problem based in the packets re-routing for analysis by a sub-network with specific filterings. The suggestion of implementa- tion of this model aims reducing the performance problem and opening a space for the consolidation of scenes where others not conventional filtering solutions (spam blockage, P2P traffic control/blockage, etc.) can be inserted in the filtering sub-network, without inplying in overload of the main firewall in a corporative network

This study presents the results of a survey conducted in the area of English for Specific Purposes (ESP) in order to identify (1) the learning needs of students in a course in Tourism, their desires and lacks, at a federal university, with respect to use of English; (2) the needs of the present situation of teachers and the coordinator of that course as to the language; (3) the needs of the target situation of professionals (graduates) and companies with respect to this language. This research is a case study (STAKE, 1998; YIN, 2009) and was used for data collection, instruments such as questionnaires, semi-structured interviews, and document on the Tourism Course. To this end, it was adopted the theoretical basis for the constructs of English for Specific Purposes (ESP) Inglês para Fins Específicos (IFE) in Brazil, also known as Inglês Instrumental, whose foundation is based on the work by Hutchinson and Waters (1987), Robinson (1991), Dudley-Evans and St. John (1998), Celani, Deyes, Holmes, Scott (2006), among others, since this work is devoted to a specific area, Tourism. Results show that students opined the ability to prioritize reading and speaking into the classroom. Professionals reported that the latter is an indispensable tool for entering the labor market, yet they feel unprepared and need to attend English language courses in private language schools. The testimony of company executives also point to this deficiency. Finally, the present situation of teachers reveals that, while advocating the use of English in the classroom, this is not because students prefer their mother tongue. There is also an evident lack of needs analysis. Eventually, the coordinator said that there is some uncertainty as to the methodology, content and language skills worked, and the lack of interaction among teachers of English. It was concluded, therefore, it is important to conduct a needs analysis so that one can redesign a course that meets the different contextual needs: students, teachers, coordination, represented by the institutional needs, and the labor market

This study is part of interactional perspective, focusing on Conversation Analysis theories, from the Textual Interactive Perspective and Text Linguistics . This research, from its guiding questions, aims at understanding the interaction between teacher and students in the process of the knowledge construction as well as at describing, analyzing and understanding aspects of topical organization speech in the classroom in elementary school, observing the opening and closing procedures of the speech topics in that particular space. Considering that the procedures for opening and closing of discursive topics occur through language marks, we tried to identify which speech marks are used in the opening and closing of the topics studied in the classroom, in interaction during the collaborative process of the discourse established between teacher and students. Therefore, this study is based on authors who analyze specific questions of the text in real context of language use: Koch (1993, 1999), Jubran et al (1991), Jubran (2006), Pine (2005), Penhavel (2010), Galembeck (2012), Barros (1991), Marcuschi (1986 , 1990, 1991 , 1998 , 1999, 2003 , 2004a), Kerbrat - Orecchioni (2006), Favero (1999, 2002) and Galvão (2004, 2010). As a methodology of investigation, the study is focused on the postulates of ethnographic research in order to carry out data collection, through audio and video recordings which were transcribed, according to the NURC project proposal, with some adaptations. Data analysis showed that the procedures for opening and closing of the speech topics occurred by the use of discourse markers, in particular the marker "then", allowing us to understand that these elements are important in the topical organization speech, contributing to ensure textual cohesion and coherence. We conclude that the organization of the discursive topic in the classroom occurs through events that support the explicitness of the content of teaching and learning, considering the diverse necessity of an institutional academic plan, whose main objective is the construction of knowledge

Nas últimas décadas, com a significativa redução da cárie dentária em crianças e adolescentes, uma maior atenção tem sido dada a outros problemas bucais como as oclusopatias. Em termos epidemiológicos no Brasil, esta tem ocupado o terceiro lugar dentre os problemas de saúde oral na população e, portanto, a inclusão destas como um problema de saúde pública se deve não apenas à sua alta prevalência, mas também ao impacto social, que interfere diretamente na qualidade de vida das pessoas. Diante do exposto é que este estudo objetiva buscar o impacto da presença e severidade das oclusopatias e suas respectivas necessidades de tratamento na qualidade de vida de adolescentes escolares de um município. Sendo assim, foram examinados 356 escolares na faixa etária de 15 -19 anos e determinadas a prevalência, severidade e necessidade de tratamento de oclusopatias através dos índices DAI, IOTN e ICON. O impacto sócio dentário das oclusopatias na qualidade de vida dos adolescentes foi analisado através do índice CS-OIDP. A fim de se verificar possíveis influências de variáveis estudadas na determinaçao do impacto na qualidade de vida das oclusopatias, estas serão coletadas através do estatus sócio-econômico, gênero, idade e tipo escola. Nos resultados parciais, relacionado a 50% da amostra, se observou uma maior prevalência do escolares de escola pública(68,1%), idade entre 15-16 anos(74,7%), gênero feminino(52,7%) e maior prevalência do SES baixo(77,5%). A análise estatística usando o teste qui-quadrado mostrou uma associação significativa do impacto da oclusopatia na qualidade de vida apenas quando avaliada com o índice ICON e o A-IOTN do examinado, comprovando uma associação da necessidade de tratamento com a presença do impacto na qualidade de vida. Com isso, busca-se comprovar e enfatizar a necessidade de se estabelecer políticas públicas que trabalhem na prevenção e interceptação dessas oclusopatias na população, melhorando, portanto, a qualidade de vida e saúde oral dos adolescentes.

Sotalia guianensis is a small cetacean of the Delphinidae family, with coastal habits and whose area of distribution ranges from Florianópolis (27º35'S, 48º34'W), in Brazil, to Honduras (15º58'N, 85º42'W). At Pipa beach, on the south coast of RN state, in Brazil, the species occur throughout the year. The present study was carried out in two bays, which are bordered by cliffs. The animals were monitored from vantage points, using the "Ad libitum" and "all the occurrences" methods; during the years of 1999 and 2004. The study was divided in 4 chapters: Behavioral standards of two populations of gray dolphin, (Sotalia guianensis, Van Benédén, 1864) in the northeast of Brazil; Aerial activity of the gray dolphin: its possible function and the influence of environmental and behavioral factors; The influence of daily and monthly variation of the tides, of the period of the day and group size on the gray dolphin forage activity; kleptoparasitism interactions of frigatebird (Fregata magnificens, Mattheus, 1914) during the gray dolphin forage activity. The results have shown that the gray dolphin has a varied and complex behavioral repertoire. The leap is the most frequent behavior; the aerial activity is diffuse during daylight and is influenced by some factors, such as the level of the tide and social factors. The gray dolphin, when in the bay, most frequently feeds isolate or in small groups. The forage is diffuse during daylight; however, being more frequent in the morning and is influenced by the daily and monthly variation of the tide. At Pipa beach, kleptoparasitarian interactions were registered between the gray dolphin and the frigatebird (Fregata magnificens). The frigatebird forage strategy consists basically of two ways: to fly over great extensions searching for dead fish and to steal food (kleptoparasitism). These interactions were predominantly carried out between immature and female adult birds and adult and immature dolphins, and occurred during daylight. The present study can be considered an initial landmark to a better knowledge on the gray dolphin surface behavior, especially regarding the aerial behavioral repertoire and forage strategy of this species. However, it is necessary to continue these studies, so that we can understand better the complex social life of these animals and thus create effective measures for its conservation

The perfect spatial intervention to manage the cultivation of the land, deriving from specific regions of the soil mapping, increases the agricultural productivity, as well as its clear gain. The relationships, spatial and Pearson, between eucalyptus data plant with some physical and chemical attributes of soil, in the growing season of 2011, in Selviria County, Mato Grosso do Sul State, Brazil (20 degrees 20' S lat.; 51 degrees 24' W long.), were studied in order to obtain the one that could have the best relationship in order to improve the wood productivity. Thus, a geostatistical grid was installed for the soil and plant data collection, it contained 120 sample points, in plantation of Eucalyptus camaldulensis of 2 years old. The soil was a Dystrophic Red Latosol (Haplic Acrustox) whit slope of 0.025m m(-1). Due to their excellent relationship with wood productivity, the basis diameter of the crown and the bulk density showed management specific regions of soil whit high relation to eucalyptus wood productivity.

A inserção das crianças de zero a 18 meses em creches poderá estimular o seu desenvolvimento motor e perceptocognitivo, podendo essa fase ser considerada a primeira da educação inclusiva. Objetivou-se verificar as concepções das profissionais do berçário relativas à inserção da criança com necessidades especiais na rotina de atividades desenvolvidas. Foram entrevistadas sete berçaristas da Secretaria Municipal de Educação de Bauru. Os dados, organizados segundo categorias analíticas: conceitos relativos ao processo de inclusão, benefícios para a criança e diferenças entre as crianças nessa faixa etária, foram submetidos à análise qualitativa. Os resultados mostraram que a inclusão de crianças com necessidades especiais é vista com reservas, explicitando ideias preconcebidas sobre a deficiência. Eles se justificam pela falta de conhecimento do desenvolvimento infantil e dos fatores que o envolvem, bem como pelo fato de os profissionais vincularem suas atividades às experiências pessoais.

A educação inclusiva envolve dimensões político-administrativas e pedagógicas. O currículo é umas dessas dimensões, e as adequações curriculares aparecem como uma estratégia para que sejam atendidos os princípios de uma escola para todos. Este estudo objetiva caracterizar o campo de estudos da educação inclusiva, por meio de uma revisão da literatura publicada entre os anos 2000 e 2010, em periódicos da área de educação, disponíveis no banco de dados Scielo. As palavras-chave utilizadas foram curricular, currículo, deficiência, educação especial e necessidades especiais. Os resultados demonstram que as produções na área são escassas no que diz respeito às estratégias para efetivação da educação inclusiva, limitando-se, prioritariamente, a reflexões e discussões teóricas que envolvem os princípios e políticas educacionais, pouco retratando experiências didático-pedagógicas que promovam ajustes curriculares e/ou formas de flexibilização do ensino.

Tendo em vista os atuais preceitos socioconstrutivistas da Ciência e da Educação em Ciências, neste estudo, o nosso objetivo foi analisar a vertente epistemológica em artigos científicos que tratam de linguagem escrita. Para tanto, analisamos o conteúdo de seis desses artigos, baseando-nos em indicadores educacionais: concepções de ciência, de sujeito, de linguagem e de intervenção fonoaudiológica. A análise destas concepções, em seu conjunto, nos permitiu o enquadramento do conteúdo desses artigos em uma vertente epistemológica mais ou menos técnica ou humanista, lógico-positivista ou pós-positivista, e, ainda, inferir sobre as implicações dessas vertentes na construção de um conhecimento pedagógico e educacional no campo da Fonoaudiologia, para a formação continuada e em serviço de um profissional fonoaudiólogo capaz de atuar também na escola. Os resultados mostraram que as visões dos autores dos artigos analisados se enquadram em uma vertente predominantemente lógico-positivista, o que aponta para a importância de reestruturar os cursos formadores desses profissionais com base em preceitos de Educação em Ciência e à luz de uma nova Filosofia da Ciência.
