A internet oferece uma ampla variedade de materiais didáticos que podem ser utilizados no processo ensino-aprendizagem. Estes materiais podem ser utilizados em diversas disciplinas e são encontrados em vários formatos. Contudo, percebeu-se a necessidade e a importância em adotar um padrão que vise a organização e o sequenciamento dos objetos de aprendizagem proporcionando seu reuso e interoperabilidade entre ambientes virtuais de aprendizagem, considerando o
planejamento pedagógico, a acessibilidade e o efetivo uso desses objetos, obtendo assim uma melhoria significativa na qualidade da metodologia utilizada em projetos de aprendizagem. Este trabalho realiza uma análise crítica de objetos de aprendizagem existentes, além de analisar o
Reload-LDEditor que na sua essência oferece um ambiente claro e preciso para o desenvolvimento de um projeto de aprendizagem, desde a descrição dos papéis, representada por um conjunto de pessoas, até a criação do ambiente estruturado, contendo objetos de aprendizagem e serviços
a serem utilizados pelas atividades propostas na unidade de aprendizagem. Essa abordagem foi validada através da modelagem de um estudo de caso realizado no contexto da disciplina Lógica e Técnicas de Programação ministrada no Campus Coari, do Instituto Federal de Educação, Ciência e
Tecnologia do Amazonas.

Com o frequente uso de Ambientes Virtuais de Aprendizagem (AVA) em instituições de ensino, é necessário que coordenadores e administradores gerenciem efetivamente os cursos de Educação a Distância (EaD), a fim de garantir um bom acompanhamento e níveis de qualidade superior. Este artigo apresenta uma abordagem baseada em um Sistema Multiagente para a questão do acompanhamento de cursos EaD. Sendo assim, este perfil de usuário poderá ter uma visão gerencial, ampla e automática de cada curso, além de obter relatórios organizados pelos agentes inteligentes, e que de forma proativa, também devem perceber no AVA situações específicas e enviar notificações imediatamente ao gestor, possibilitando uma rápida tomada de decisão.

Atualmente, a tecnologia está presente na sociedade e nos mostra diferentes meios de interação. A Realidade Virtual (RV) é uma dessas maneiras, de modo que sua aplicação tem trazido novas experiências imersivas em diversos âmbitos, como na educação. Logo, é possível observar que atividades externas à sala de aula contribuem para a formação do aluno, através de excursões que podem proporcionar experiências em ambientes que levam o conhecimento de maneira prática. Com isso, a empresa Google resolveu explorar o uso da RV nas instituições de ensino através da criação do dispositivo Cardboard Glasses, para que os estudantes pudessem conhecer diversas localidades sem sair de sala de aula. Partindo desse princípio, a motivação deste trabalho consiste em auxiliar os professores das disciplinas de Geografia e Ciências aplicando a ferramenta Cardboard e o aplicativo Expeditions como recurso metodológico no processo de ensino-aprendizagem de alunos do 2o, 6o e 9o anos do ensino fundamental em ...

Isto poderá ser alcançado por meio de U.M.E., um jogo digital e interativo, no qual ajudará a criança a compreender os problemas ambientais decorrentes das atitudes humanas, mostrando caixas de diálogo como modo de comunicação. O jogo tem como personagem principal um droide, que é responsável por alertar sobre as ações de degradação do meio ambiente e como preservá-lo.

This paper presents a methodology for identifying metamorphic malware based on the comparison of dependency graphs stored in a reference. On the strength of the structural differentiation of the vertices and the addition of virtual structures, the proposed methodology is able to identify and eliminate non-relevant elements of the original reference graph, reducing the size of the reference database and improving the results obtained during the comparison of the graphs. To validate this, is presented the comparison of results generated by the proposed approach with those from a reference method in the identification of W32.Evol and W32.Polip metamorphic malwares.

The development of community support environments requires a big effort when educational context is adopted. In this way, it's important to work with technologies to minimize implementational effort, offers reusability and allow adaptations to particular situations. This paper shows an experience on building a learning object that gathers the functions of a chat-room and a whiteboard, and it's integration with a telematic environment that supports learning. Resumo. A criação de ambientes de apoio a comunidades virtuais demanda um esforço bastante dispendioso, principalmente quando se trata de contextos educacionais. Nesse sentido, é importante contar com tecnologias que minimizem o esforço implementacional, favoreçam a reusabilidade e permitam adaptações a situações particulares. Esse artigo relata uma experiência na construção de um objeto de aprendizagem, que agrega as funções de sala de bate-papo e quadro branco, e na sua integração com um ambiente telemático de apoio a aprendizagem.

The services that river vessels have provided to Amazonian communities, from the most remote to the great metropolises, are so essential that it is likely that without them the very livelihoods and survival of the peoples of the region would be compromised. Because of their importance, these vessels have become true regional institutions, so it is essential to know their level of service, which corresponds to the satisfaction that their users have in relation to the services available to them. As satisfaction is also due to the services provided by the ports where they dock, it is necessary to investigate the service levels of these ports. This study aimed to evaluate if the service level of the Manaus Moderna port is in accordance with the expectations of the vessels that dock there, according to their commanders. It used the survey method, using a semi-structured interview script focused on evaluating existing services and identifying missing services to test the hypothesis that the services offered are in line with what is expected of them; Data processing was based on simple frequencies and percentages, presented in contingency tables, whose interpretation was centered on the degree of satisfaction of the respondents (port service level) and the clients of the vessels (vessel service level). The results showed that a) only the services provided by the on-site police station cause satisfaction, b) there are numerous infrastructural services that are not available and that are necessary for vessels to operate with the minimum adequacy and c) customer satisfaction of vessels. it concerns only passenger ordering and transport services. The conclusion shows that the level of service offered by the port of Manaus Moderna to the vessels that dock there is below what is expected, according to the perception of its commanders.

Context: Environments of uncertainty and instability force organizations to modify their actions. The reason for this change is that the minimum data and information needed to establish the logic of production cannot be obtained. Objective: This study aimed to identify the impacts of the external environment on the logistics strategies of the industrial organizations operating at the Manaus Industrial Pole. Methodology: The method was the survey, which used a research protocol as a guide, and had as its subject five managers of the logistics sector of five medium and large industries operating in the industrial center of Manaus, Brazil, intentionally chosen, whose Data collection was done through semi-structured interviews and the results were generated with the aid of content analysis. Results: The results showed that a) the logistics chain is made up of foreign suppliers and domestic consumers, b) the organizations are managed by professionals with adequate technical and scientifi...

Metamorphism have been successfully used in original malicious code to the creation and proliferation of new malware instances, making them harder to detect. This work presents an approach that identifies metamorphic malware through data dependency graphs comparison. Features are extracted on data dependency graphs to build an index that is used to determine which malware family a suspicious code belongs to. Experimental results on 3045 samples of metamorphic malware showed that our proposed approach obtained accuracy rate higher than most commercial anti-malware tools.
