Diretrizes para o desenvolvimento e a avaliação de blogs de biblioteca

Blogging become popular due to its ease of use and publication, which influences the growth of digital information environments. Therefore, studies are needed to optimize the organization of information in the blog, to contribute in its development. Using the direct observation of nonparticipatory, analysis was performed on 6 blogs of university libraries to identify the elements of Information Architecture (IA) that is considered essential and optional for the structural development of a blog. Thus, were conducted planning guidelines for blogs and a model for its evaluation, and were proposed specific elements of IA for blogs, to contribute to the study of Digital Information Architecture.

Encontrabilidade da Informação: atributos e recomendações para ambientes informacionais digitais

At first, this paper presents the epistemological and theoretical bases that support the inclusion of an operational concept for the findability of information in the field of Information Science. In a second moment, it defines the key attributes and recommendations for the findability of information, with a view to their understanding in a practical perspective, from the epistemological and theoretical support presented. From a theoretical, exploratory, bibliographic and documentary study, the results reveal that epistemologically the findability of information fits in Information Science in post-custodial paradigm that focuses on access to information and is significantly influenced by Information and Communication Technologies. The theoretical conclusions of this concept focus on the evolution of the Web and from the perspective of the dimensions of language, where there is as pragmatic trend, as technological development that combines the actions taken by informational and institutional individuals in digital information environments. Given that these actions turn enable or not the findability of information, these individuals can be understood as mediators. Therefore, the concept of infocommunicational mediation is the basis for the findability of information. For its application in digital information environments, were defined attributes and guidelines which should be considered in the context of Information Architecture. The attributes characterizing the concept and guidelines point at practical actions for the design and for evaluation of the findability of information. Epistemological, theoretical and practical concepts addressed underpin the called operative concept in information science and should be further explored in this scientific field.

Acessibilidade em Ambientes Informacionais Digitais

The current nature of World Wide Web (Web), which highlights the collaborative participation of users in some digital information environments, lead to development of guidelines with a focus on Inclusive Digital Information Architecture for a different audiences in multiples informational ambiences. This research proposes guidelines for a inclusive digital information environment, aiming to identify the elements of accessibility that allow the promotion of inclusion digital information, in order to highlight the references of the Architecture of Digital Information, the international recommendations and the structures representation of information (specially accessibility attributes), with the look of Information Science and New Technologies of Information and Communication. The thesis is as to the need to develop methodologies with guidelines that contemplate the elements of digital accessibility focused on the task of the user. The research problem is that actual methodologies and recommendations used for the development of digital information environments do not cover all the elements of accessibility with a focus on user needs. The proposition is to present, through a methodological approach (exploratory and descriptive), a theoretical-methodological proposal to promote elements of digital accessibility to the development of digital information environments, for users with or without special needs. The overall objective of this study is to contribute to the development of inclusive digital information environments, in perspective of union of theories, recommendations and technologies for the development of digital accessibility guidelines. In a theoretical dimension, the research covers a critical review of the specialized literature in the areas of Information Science and Computer Science and, in the applied part, the analysis and development of a proposal of guidelines for the architecture of a digital information environment with accessibility.

A CASE tool for the modeling of methods and information systems

MODSI is a multi-models tool for information systems modeling. A modeling process in MODSI can be driven according to three different approaches: informal, semi-formal and formal. The MODSI tool is therefore based on the linked usage of these three modeling approaches. It can be employed at two different levels: the meta-modeling of a method and the modeling of an information system.In this paper we start presenting different types of modeling by making an analysis of their particular features. Then, we introduce the meta-model defined in our tool, as well as the tool functional architecture. Finally, we describe and illustrate the various usage levels of this tool.

A medical information system to manage a cancer database

Cancer is the second main cause of death in Brazil, and according to statistics disclosed by INCA - National Cancer Institute 466,730 new cases of the disease are forecast for 2008. The storage and analysis of tumour tissues of various types and patients' clinical data, genetic profiles, characteristics of diseases and epidemiological data may provide more precise diagnoses, providing more effective treatments with higher chances for the cure of cancer. In this paper we present a Web system with a client-server architecture, which manages a relational database containing all information relating to the tumour tissue and their location in freezers, patients, medical forms, physicians, users, and others. Furthermore, it is also discussed the software engineering used to developing the system.

Une architecture sensible au contexte pour le développement des systèmes d'administration pour l'enseignement

The increasing use of mobile devices and wireless communication technologies has improved the access to web information systems. However, the development of these systems imposes new challenges mainly due to the heterogeneity of mobile devices, the management of context information, and the complexity of adaptation process. Especially in this case, these systems should be runable on a great number of mobile devices models. In this article, we describe a context-aware architecture that provides solutions to the challenges presented above for the development of education administration systems. Copyright 2009 ACM.

Architecture for peer-to-peer databases with routing queries using ant colony algorithm and semantic support

In a peer-to-peer network, the nodes interact with each other by sharing resources, services and information. Many applications have been developed using such networks, being a class of such applications are peer-to-peer databases. The peer-to-peer databases systems allow the sharing of unstructured data, being able to integrate data from several sources, without the need of large investments, because they are used existing repositories. However, the high flexibility and dynamicity of networks the network, as well as the absence of a centralized management of information, becomes complex the process of locating information among various participants in the network. In this context, this paper presents original contributions by a proposed architecture for a routing system that uses the Ant Colony algorithm to optimize the search for desired information supported by ontologies to add semantics to shared data, enabling integration among heterogeneous databases and the while seeking to reduce the message traffic on the network without causing losses in the amount of responses, confirmed by the improve of 22.5% in this amount. © 2011 IEEE.

Use of myoelectric signals to command mobile entertainment robot by disabled children: Design and control architecture

Severely disabled children have little chance of environmental and social exploration and discovery. This lack of interaction and independency may lead to an idea that they are unable to do anything by themselves. In an attempt to help children in this situation, educational robotics can offer and aid, once it can provide them a certain degree of independency in the exploration of environment. The system developed in this work allows the child to transmit the commands to a robot through myoelectric and movement sensors. The sensors are placed on the child's body so they can obtain information from the body inclination and muscle contraction, thus allowing commanding, through a wireless communication, the mobile entertainment robot to carry out tasks such as play with objects and draw. In this paper, the details of the robot design and control architecture are presented and discussed. With this system, disabled children get a better cognitive development and social interaction, balancing in a certain way, the negative effects of their disabilities. © 2012 IEEE.

Molecularly designed layer-by-layer (LbL) films to detect catechol using information visualization methods

The control of molecular architectures has been exploited in layer-by-layer (LbL) films deposited on Au interdigitated electrodes, thus forming an electronic tongue (e-tongue) system that reached an unprecedented high sensitivity (down to 10-12 M) in detecting catechol. Such high sensitivity was made possible upon using units containing the enzyme tyrosinase, which interacted specifically with catechol, and by processing impedance spectroscopy data with information visualization methods. These latter methods, including the parallel coordinates technique, were also useful for identifying the major contributors to the high distinguishing ability toward catechol. Among several film architectures tested, the most efficient had a tyrosinase layer deposited atop LbL films of alternating layers of dioctadecyldimethylammonium bromide (DODAB) and 1,2-dipalmitoyl-sn-3-glycero-fosfo-rac-(1-glycerol) (DPPG), viz., (DODAB/DPPG)5/DODAB/Tyr. The latter represents a more suitable medium for immobilizing tyrosinase when compared to conventional polyelectrolytes. Furthermore, the distinction was more effective at low frequencies where double-layer effects on the film/liquid sample dominate the electrical response. Because the optimization of film architectures based on information visualization is completely generic, the approach presented here may be extended to designing architectures for other types of applications in addition to sensing and biosensing. © 2013 American Chemical Society.
