This paper provides a brief description of the Brazilian Atomic Time Scale System that generates the UTC(ONRJ). Also describes the international comparison of the UTC(ONRJ) in the last year by using data from Circular T and UTC rapid.
The present article consists of a qualitative, descriptive-interpretative systematic review, whose objectives are (1) to present which teaching-learning approaches are most used in the development of oral skills through digital technologies; (2) investigate which tools are the most used to develop oral skills in digital environment; (3) what aspects of orality are being the most studied and (4) what possibilities and restrictions are indicated. We analyzed 56 papers, among articles, dissertations and thesis collected from three databases. The implications of this work also point to research gaps in the area, such as the absence of studies on critical perspectives in the work with technology and orality, and the lack of research that deals with the question of orality via ICT in the initial and continuing training of LE teachers.
RESUMO: Neste estudo, analisamos composições multimodais instrucionais em um contexto específico de ensino a distância com o objetivo de lançar luzes sobre como os processos de interação entre os modos de expressão visual e escrito se delineiam no contexto escolhido. Para isso, escolhemos a perspectiva das relações de status e lógico-semânticas desenvolvidas por Martinec e Salway e levamos em consideração também as interações semióticas delineadas por Roland Barthes. Foi escolhida como objeto de análise uma disciplina de um curso de Licenciatura em Letras -modalidade a distância. A disciplina tem como objetivo principal o desenvolvimento das habilidades orais (audição e fala) e o desenvolvimento de aspectos da escrita ligados ao conteúdo estudado. Os resultados preliminares mostraram que a teoria de análise dessas interações proposta por esses autores tem muito a oferecer a nós, professores, na tarefa de ajudar os alunos no esclarecimento de como as interações entre os modos semióticos se constituem. Percebemos também que o potencial de contribuição para o aprendizado que pode ser oferecido por cada modo precisa ser mais bem compreendido para que possamos facilitar o processo de letramento de nossos aprendizes em composições multimodais. PALAVRAS-CHAVE: Interação imagem-texto; Relações lógico-semânticas.ABSTRACT: This study analyzes multimodal instructional compositions from the specific context of distance learning in an attempt to shed light on how the processes of interaction between modes of visual expression and writing are outlined in this context. We applied the perspective of the relations of status and logical semantics developed by Martinec and Salway, as well as the semiotic interactions developed by Roland Barthes. A class of a Language and Literature teaching degree course, distance mode, was chosen as subject of analysis. This class mainly aims to develop oral skills (listening and speaking) and writing aspects related to the studied content. Preliminary results showed http://dx
