A frase portuguesa: uma visão lógico-semântica e a sua estruturação sintática

Considerando-se que a representação lingüística do universo em que vivemos se baseia na existência de OBJETOS e PROCESSOS, sendo que através desses PROCESSOS se atribuem qualidades, ações, estados, etc. aos OBJETOS, procurou-se, neste artigo, conceituar a FRASE como sendo a unidade dessa representação. E considerando-se o VERBO como centro estruturador da FRASE, procurou-se demonstrar que esta se realiza na base de um SUJEITO e um PREDICADO, cujos PARTICIPANTES obrigatórios se distribuem em níveis hierarquizados.

Um olhar sobre a formação de professores de matemática a distância

Os professores de Matemática, assim como os que ensinam as demais disciplinas nos cursos de nível fundamental e médio, deparam com vários fatores desestimulantes:fraco desempenho dos alunos, currículos desinteressantes, deficiência na própria formação. Diante desse quadro, a autora investigou uma alternativa à formação tradicional de professores de Matemática. Ela analisa a educação a distância para tentar identificar se esse meio seria adequado para promover tanto a formação inicial quanto a continuada dos docentes da disciplina. Ela se baseia em um caso exemplar: o curso de licenciatura em Matemática a distância do Centro de Educação Superior a Distância do Rio de Janeiro (Cederj), que integra a Universidade Aberta do Brasil (UAB), ligada ao Ministério da Educação. O curso serve de modelo para outros cursos da UAB. A autora apresenta a implementação do projeto desde a etapa inicial, avaliando documentos e um grande volume de entrevistas, principalmente com alunos formados no curso, mas também com professores e gestores. O estudo capta diversos aspectos do curso da Cederj/UAB, como as expectativas dos alunos em relação ao processo de ensino e aprendizagem, as dificuldades que encontraram, a forma como tinham acesso às aulas a distância, o comportamento diante dos colegas nos encontros presenciais e os resultados práticos da formação. As conclusões da autora incluem pontos positivos e deficiências, mas ela levanta subsídios importantes para a discussão sobre o uso do instrumento educação a distância na formação de professores de Matemática.

Utilização da distância total percorrida no teste específico de hoff como preditor da velocidade de limiar anaeróbio no futebol

OBJECTIVE: To verify the use of maximal running distance performed on Hoff test to predict the anaerobic threshold speed (sAnT). METHODS: Ten young soccer players (age of 17 ± 1 years and body mass of 64.3 ± 2.1 kg) were subjects of the study. The subjects performed 12-min test, lactate minimum test to estimate the anaerobic threshold speed and a field test called Hoff. The purpose of Hoff test was to cover the maximum distance during a period of 10min moving a soccer ball through the track by dribbling. RESULTS: The distance covered during 12-min was 2673.2 ± 64.7 m, the sAnT was 11.6 ± 0.3 km.h-1 and distance covered during test Hoff test was 1458.7 ± 49.6 m. The distance covered during Hoff test was not significantly correlated with sAnT (r = -0.20; P > 0.05) and distance covered during 12-min test (r = -0.15; P > 0.05). The sAnT did not differ of speed correspondent 90% at 12-min speed and they were statistically correlated (r = 0.65). CONCLUSION: Thus, we concluded that maximal distance covered during Hoff test cannot provides a valid prediction of the anaerobic threshold speed.

Objetos de Aprendizagem como recurso pedagógico em contextos inclusivos: subsídios para a formação de professores a distância

This article aims to contribute to the process of inclusion of students with disabilities in regular schools by reporting the results of a survey that aimed to verify whether Learning Objects (LO) are efficient tools in constructing teaching and learning of subject content within the inclusive education context. Participant, tutor and trainer experiences of a distance learning Ministry of Education (MEC) course on Assistive Technology were analyzed. The course was offered to public schools teachers from all over the country. The course activities were recorded in a Virtual Learning Environment (VLE) called TelEduc, along with group reports of course participants. Three categories were selected for data analysis: a) interactivity and feedback from the team trainer; b) applicability of the content covered in the course, and c) new learning. The results showed that LO can promote the learning of subject content. Having been designed as educational resources to support teaching and learning, they can enhance educational inclusion of people with disabilities. As for the process of distance formation for teachers, the course contributed to consolidating sound and efficient training of participants by providing: a closer encounter with the world of technology, the possibility of integration of technology in the classroom; conducting theoretical and practical studies, appreciation of diversity and all students' potential; innovations in strategies and learning resources and reflective action.

Educação continuada do catalogador na modalidade a distância: uma proposta alternativa

This paper presents a proposal for the teaching of cataloguing, emphasizing the problem-solving methodology. The proposal was designed for the distance-based continuing education of the professional cataloguer. It takes into account the challenges inherent to the development of interactive and inter-disciplinary tasks, as well as the development of directed self-education and critical consciousness of that professional, inasmuch as he becomes an active subject, manager of his/her own education.

Modelos de recuperação de informação e web semântica: a questão da relevância

Introduction: In the Web environment, there is a need for greater care with regard to the processing of descriptive and thematic information. The concern with the recovery of information in computer systems precedes the development of the first personal computers. Models of information retrieval have been and are today widely used in databases specific to a field whose scope is known. Objectives: Verify how the issue of relevance is treated in the main computer models of information retrieval and, especially, as the issue is addressed in the future of the Web, the called Semantic Web. Methodology: Bibliographical research. Results: In the classical models studied here, it was realized that the main concern is retrieving documents whose description is closest to the search expression used by the user, which does not necessarily imply that this really needs. In semantic retrieval is the use of ontologies, feature that extends the user's search for a wider range of possible relevant options. Conclusions: The relevance is a subjective judgment and inherent to the user, it will depend on the interaction with the system and especially the fact that he expects to recover in your search. Systems that are based on a model of relevance are not popular, because it requires greater interaction and depend on the user's disposal. The Semantic Web is so far the initiative more efficient in the case of information retrieval in the digital environment.

Sintaxe e semântica de registros bibliográficos: princípios para a conversão de registros analógicos para o formato MARC21 bibliográfico: Scan for MARC

The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

Ontologias, categorias e interoperabilidade semântica

Explores the concept of interoperability as a means of cooperation, stressing the importance of promoting them from consistent information policies. Highlights the dependence of interoperability to the variations of language that account for sociocultural differences and associates its realization to common ontology construction as a means of enabling structures that can be integrated. Emphasizes the importance of using categories to provide the entire organization and to facilitate access by offering support the process of categorizing on concrete terminologies of specific domains and areas of activity, discourse communities references or of the speeches actually made.
