Preservação digital nas instituições de ensino superior: aspectos organizacionais, legais e técnicos

This article analyzes the main aspects related to digital preservation in Higher Education Institution (HEI). Discusses the problems and challenges to be facing in this context and presents the main aspects and strategies involving digital preservation in this institution type, focusing on three: the organizational aspects, the legal aspects and the technical aspects. The methodological procedures involved the literature analysis on the subject area. As a result shows a digital preservation policy that includes 15 (fifteen) essential elements, distributed in three segments (aspects), and the importance of each element to the deployment of a digital preservation policy.

Anatomical evaluation of the cervical vertebrae of Wistar rats by means of digital radiographs and its correlation with the maturation stages of human cervical vertebrae

INTRODUCTION: Biological age is an important parameter for growth and development assessment. It can be evaluated through the observation of radiographic changes in skeletal maturation of cervical vertebrae. OBJECTIVE: This study aims to: a) verify if there is correlation between growth curve and the stages of bone age of animals used in laboratories, by evaluating radiographs of the cervical vertebrae; b) correlate these stages with their correspondents in humans. METHODS: 35 Wistar rats were evaluated for a period of 160 days, starting at day 22nd (weaning), with cross sections for periodic weighing, length measurement and digital radiography. Radiographs of the cervical vertebrae (C2 and C3) were measured by means of a computer program (Radio IMP). Data were submitted to statistical analysis (ANOVA) and Pearson correlation. RESULTS: Growth spurt was characterized by fast increasing in weight and length. Through ANOVA, differences were observed in the cervical measurements between days 22, 97, 127, 157, 187 and 217 (p <0.001). A high correlation was found between increasing in body length and weight, as well as in cervical vertebrae height (r = 0.86). Increments in concavities of vertebrae were also observed, similar to humans. CONCLUSIONS: There is correlation between body growth and maturation of cervical vertebrae in rats. Despite the continuous development of concavities, it was not possible to clearly identify the 5/6 stages as in studies of cervical vertebrae maturation in humans.

The Digital Divide in the University: The Appropriation of ICT in Higher Education Students from Bogota, Colombia

The growth and integration of ICTs in the global economy have created conditions that profoundly affect our society, dividing communities between those who effectively appropriate these resources and those who do not, what is called the digital divide. This exploratory study seeks to propose and validate ways of assessing this phenomenon in higher education, from the construction of a model and a comprehensive methodology that value contextual conditions, in addition to measuring access factors and motivation for use, that have been employed in previous research. To obtain indications about the behavior of this phenomenon, we developed research with students from three universities in Bogota, administering 566 surveys in four phases that would test the variables proposed in the model. The results show that the variables of the model link causally, with the strongest relations between education, attitude towards ICTs and ICT application. Although students have good access to ICTs and high levels of education, no strong relationship was found in regards to perceived impact on production. This may be explained by a superficial appropriation of ICT, due to a context that is alien to its conditions of origin (industrialism, innovation), poor quality of education and economies not centered around R&D.

DIGITAL ELEVATION MODEL VALIDATION WITH NO GROUND CONTROL: APPLICATION TO THE TOPODATA DEM IN BRAZIL

Digital Elevation Model (DEM) validation is often carried out by comparing the data with a set of ground control points. However, the quality of a DEM can also be considered in terms of shape realism. Beyond visual analysis, it can be verified that physical and statistical properties of the terrestrial relief are fulfilled. This approach is applied to an extract of Topodata, a DEM obtained by resampling the SRTM DEM over the Brazilian territory with a geostatistical approach. Several statistical indicators are computed, and they show that the quality of Topodata in terms of shape rendering is improved with regards to SRTM.

A mediação da informação nos arquivos permanentes: serviços de referência arquivística no ambiente digital

Information Science has for its object of study the general properties of information and analysis of their construction, communication and use processes. Organic information, one of the information types, is the one recorded in the archives, which can be split into two distinct groups based on users: current and permanent, used by administrators, historians/citizens, respectively. After defining the information behavior of each group, the articles directs the discussion to the mediation of information in the permanent archives. The interaction between user and information professionals through references services aiming the user needs is presented. In addition, the standards of archival description and the research instruments as tools to reference service are discussed. Moreover, it argues the importance of information technologies and the new possibilities for the promotion of organic information in permanent archives, especially concerning the information architecture of websites and the conversion of the DTD standards of archival descriptions.

DEVELOPMENT OF AN ALGORITHM TO ANALYZE CARTOGRAPHIC FEATURES EXTRACTION METHODS IN DIGITAL IMAGES

The algorithm creates a buffer area around the cartographic features of interest in one of the images and compare it with the other one. During the comparison, the algorithm calculates the number of equals and different points and uses it to calculate the statistical values of the analysis. One calculated statistical value is the correctness, which shows the user the percentage of points that were correctly extracted. Another one is the completeness that shows the percentage of points that really belong to the interest feature. And the third value shows the idea of quality obtained by the extraction method, since that in order to calculate the quality the algorithm uses the correctness and completeness previously calculated. All the performed tests using this algorithm were possible to use the statistical values calculated to represent quantitatively the quality obtained by the extraction method executed. So, it is possible to say that the developed algorithm can be used to analyze extraction methods of cartographic features of interest, since that the results obtained were promising.

Comunicação pública e democracia digital nos processos de participação cidadã: uma análise do Portal Brasil, sob os princípios de E-engagement

This article conducted an analysis of Portal Brazil, specifically in the areas of “Education” and “Economy and Employment”, by according to the principles of e-engagement defined by the Organization for Economic Co- operation and Development (OECD). For understanding of this work, were elucidated concepts such as public communication - trajectory, principles and relations -, digital democracy, e-government and engagement and civic participation. Through this analysis was realized the importance of public communication in the processes of opinion formation and stimulus to citizen participation, as well as the performance of the internet as a facilitator instrument in the processes of relationship between State and Society
