Estratégias de aprendizagem utilizadas por estudantes cegos

Learning strategies can be understood as a planned sequence of procedures or activities, selected in order to facilitate the acquisition, storage and use of information. Although important to the learning process, the knowledge on these strategies is still insufficient, especially with regard to students with visual impairments. Therefore, this study aimed to characterize learning strategies used by blind and sighted students, registered in elementary education in schools and special institutions. Were participants 23 teachers, male and female, aged between 26 and 51 years, and 102 students, of whom 25 were blind and 77 seers, of both genders, registered on the 3rd to the 9th grade of elementary school, aged 7 to 16 years old. The instruments used were: field diary (students and teachers); structured questionnaire (teachers); sociodemographic questionnaire, interview and Assessment Scale of Learning Strategies for Elementary School (students). Initially were made observations in the classroom and the teachers received the questionnaires, with instructions for completion. Then were made the interviews with blind students and the scale was administered with these and with the seers. All instruments were administered individually. We conducted content analysis of the questionnaires with teachers and the interviews with blind students. The scale of strategies and sociodemographic questionnaire were analyzed with the help of descriptive and inferential statistics. It was noticed that the blind students use few learning strategies in the classroom, regardless of city, series, sex or age. It was found that teachers didn t receive training to deal with blind students, either during graduation or after have completed it, in such a way that few of them were able to inform about the learning strategies the students use, and demonstrated low ability to deal with these inefficiencies. It was also found that the blind and the sighted use cognitive and metacognitive strategies during learning, but those used by the blind seem to be more basic, low complexity, given that the seers have achieved higher scores on all subscales. We conclude that the repertoire of learning strategies for blind students is inflexible, requiring increments so that they can achieve significant results. It is important that teachers receive training to understand the learning strategies and how they positively influence learning

Extensões ao Projeto LVWNet: mobilidade, interação com equipamentos reais, comunicação direta, e registro dinâmico de nós

Due to the constantly increasing use of wireless networks in domestic, business and industrial environments, new challenges have emerged. The prototyping of new protocols in these environments is typically restricted to simulation environments, where there is the need of double implementation, one in the simulation environment where an initial proof of concept is performed and the other one in a real environment. Also, if real environments are used, it is not trivial to create a testbed for high density wireless networks given the need to use various real equipment as well as attenuators and power reducers to try to reduce the physical space required to create these laboratories. In this context, LVWNet (Linux Virtual Wireless Network) project was originally designed to create completely virtual testbeds for IEEE 802.11 networks on the Linux operating system. This paper aims to extend the current project LVWNet, adding to it the features like the ability to interact with real wireless hardware, provides a initial mobility ability using the positioning of the nodes in a space coordinates environment based on meters, with loss calculations due to attenuation in free space, enables some scalability increase by creating an own protocol that allows the communication between nodes without an intermediate host and dynamic registration of nodes, allowing new nodes to be inserted into in already in operation network

Análise da mobilidade urbana de Natal/RN a partir do uso de indicadores de sustentabilidade

In contemporary times, the urban mobility is presented as one of the main challenges of large and medium-sized Brazilian cities , it presents signs of unsustainability , above all due to the increase in motorized transport system , especially the individual . Thus , it is clear that mobility is considered of special interest for sustainable urban development , is facing a crisis that is reflected in negative externalities , particularly with regard to congestion , accidents , air pollution , social exclusion , among others. The complexity of these problems requires an integrated analysis based on the principles of sustainability . In this sense , trying to understand this problem and in the attempt to minimize its impacts, Costa (2008 ) proposed the Index of Sustainable Urban Mobility (I_SUM) with the goal of providing a methodology capable to assess relevant aspects of mobility , including social dimensions , political, economic and environmental . Given the above, was elected as the main objective of this study is to analyze urban mobility in Natal / RN from the perspective of sustainability . Like specific objectives will seek to analyze Natal´s urban mobility, using the I_SUM like a tool for both the city as a whole and for each of its four administrative regions; evaluate Natal s urban accessibility conditions and verify to what extent the access to urban services and equipment is facilitated or hindered because of the location and incomes of the population . For this, it was necessary to use bibliographic , documentary and field research . The index , which varies from 0.00 to 1.00, revealed for Natal an Global value of 0,510, and that refers to its administrative regions, it was found that there are very small percentage differences from the overall index calculated for the city . The performance of I_SUM by administrative region showed that although there are differences , the results were very similar , varying between 0,494 and 0,537. Particularly in relation to urban accessibility, it appears that Natal presents as an unequal city and this inequity , which is not only income is reflected in the issues related to accessibility and hence urban mobility

Orientação de falhas presentes em testemunhos de sondagens do campo de Xaréu/bacia do Ceará

A research project is being developed by PPGG/UFRN and PETROBRAS in the Xaréu Oil Field located in Ceará Basin, Northeastern Brazil. The objective of the research is to characterize a fractured carbonate reservoir, the Trairi Limestone, in order to drill a borehole with two horizontal legs taking advantage of the natural fracture system to enhance the oil recovery. The present master thesis is part of this research and its contribution is to estimate fault orientation from unoriented cores, using the method proposed by Hesthammer & Henden (2000). In order to orient a fault cutting a bed observed in the core, the bed should be previously oriented. As additional constraint to orient the bed, we use regional bedding orientation obtained from structure maps of Trairi Limestone. Because the number of cores drilled from the Trairi Limestone was too small, we analyzed all cores from the field. As geologic constraint, we admit that all faults were formed as result of the South America and Africa separation, in the context of a regional dextral strike-slip fault formation. In this context, secondary faults are manly T and R faults according Riedel s classification. We analyzed 236.5 m of cores. The dip of bedding varies from 0o to 8o, being the most frequent value equal to 2o. We interpret this result as evidence that the deformation process was manly ruptil. 77 faults were identified in the cores. These faults strike manly to NW and NE with dips, in general, inside the interval 700 - 900. We suggest that the horizontal legs of the borehole should be oriented to NW and NE in order to improve the probability of intercepting open fractures and faults

Orientação e magnitude de tensões na bacia potiguar: implicações para evolução de bacias em margens passivas

This study presents new stress orientations and magnitudes from the Potiguar basin in the continental margin of Brazil. We analyzed breakout and drilled induced fractures derived from resistivity image logs run in ten oil wells. We also used direct Shmin measurements determined from hydraulic fractures and rock strength laboratory analysis. In addition, we compared these results with 19 earthquake focal mechanisms located in the crystalline basement. We observed that stress directions and magnitudes change across the basin and its basement. In the basin, the SHmax gradient of 20.0 MPa/km and the SHmax/Shmin ratio of 1.154 indicate a normal stress regime from 0.5 to 2.0 km, whereas the SHmax gradient of 24.5MPa/km and the SHmax/Shmin ratio of 1.396 indicate a strike slip stress regime from 2.5 to 4.0 km. The deeper strike-slip stress regime in the basin is similar to the regime in the basement at 1-12 km deep. This stress regime transition is consistent with an incipient tectonic inversion process in the basin. We also noted that the SHmax direction rotates from NW SE in the western part of the Potiguar basin to E W in its central and eastern part, following roughly the shoreline geometry. It indicates that local factors, as density contrast between continental and oceanic crust and sediment loading at the continental shelf influence the stress field. The concentration of fluid pressure in faults of the lowpermeability crystalline basement and its implications to establish a critically stressed fault regime in the basement is also discussed

Território usado e transporte coletivo : mobilidade e acessibilidade no Bairro Lagoa Azul Natal/RN

Transport systems involved the use of territory in different Brazilian cities with regard to the occupation of road systems in urban areas. The implementation of systems engineering and transport infrastructure such as roads (roads), signs, stops, stations and complex road (bridges, viaducts and tunnels) are not used in the same way in the area. The subway is not even use the bus and vice versa. The time spent in travel, the time to access and the number of trips made by passengers in each way of transport is not the same. The use of transport systems in the territory, therefore, takes place through a whole in the current period we are in the technicalscientific and informational. This work addresses, however, the area used as a synonym of geographical area, analyzed by two categories of analysis, systems of objects formed by the fixed and the systems formed by the action flows. The system analyzed is the public transport by bus and population displacement that makes using this medium with source destination from home to work and has as empirical cut the Lagoa Azul located in the district administrative area north of Natal / RN. The general objective of this research is to understand the extent to which public transport has contributed to the socio-spatial accessibility of the residents of Barrio Blue Lagoon, located in Natal-RN, emphasizing the way home and the workplace. To reach the general objective of this dissertation, a study was made in light of the line which the methodological empirical facts, statistical data and theoretical knowledge of the events that occur in the quarter related to the Lagoa Azul economic aspects. Use for this, the concepts of mobility and Accessibility

Orientação geográfica: uma proposta metodológica para o ensino da geografia na 5ª série

Cartographical representations (maps, charters and plans) are taken as didactic resources in Geography classes in the 5th grade of the municipal public schools in São José de Ribamar through a methodological approach taking into consideration the use of those resources is still worries an important part of the teachers of the Maranhão State public schools who teach in this level. Papers related to the theme, most of the time, are non accessible to the teachers of the maranhense public schools, mainly because the education instilutions, which use those resources, do it in a very incipient way. So this research proposes from the drawings of magnetccoursein the school courtyards, together with maps, charts, plans among others representation used in the classroom environment, motivate the students to a deeper interests in participating in Geography learning process in the 5th grade. Interviews, analyses of socialcultural questionnaires of the families involved in the process; observations of classes, trainings, geocartographical orientations, application of pre and posttests, discussions about the usage of cartographic representations, proposed and effectivated tasks in the classroom, as well as around the school, were the basis of the researched population. As a result of this process, it was produced a was complement didatical material showing, among others, the space in which students, for sure, will contribute in an effective way to a better teaching practice in the chain of maranhense public schools, having in mind that these geographic subjects may be taught in the level we focused our study

Efeito de um programa de treinamento de facilitação neuromuscular proprioceptiva sobre a mobilidade torácica

A proposta deste estudo foi analisar o efeito de um programa de treinamento de membros superiores baseado nas técnicas de facilitação neuromuscular proprioceptiva (FNP) sobre a mobilidade torácica. Foram estudadas 24 voluntárias sedentárias, idade 22,9 ± 2,9 anos, divididas em grupo controle (GC), que não participou do treinamento, e grupo treinado (GT). O protocolo de treinamento físico foi constituído por um programa de exercícios de FNP, realizado três vezes por semana, durante quatro semanas. Os dois grupos foram submetidos à avaliação da mobilidade torácica por meio de cirtometria, antes e após o período de treinamento. Os dados colhidos foram analisados estatisticamente, com nível de significância α = 5%. Os valores da cirtometria axilar e xifoideana do GC antes e após o período de intervenção não apresentaram alterações significativas (p>0,05). No GT os valores das variáveis foram significantemente maiores após a intervenção (p<0,05). em conclusão, o protocolo de FNP utilizado parece ser um programa de exercícios eficiente, por promover aumento na cirtometria em um curto período de tempo, sugerindo que pode ser utilizado como recurso fisioterapêutico para o desenvolvimento da mobilidade torácica.
