Barracas de Praia, praia de barracas: configuração, tipo e usos na praia do futuro, Fortaleza CE

The purpose of this dissertation is to analyse the importance of the huts of Praia do Futuro to their users and to the city of Fortaleza in Ceará through the comprehension of relations between morphological categories - in urban and edified contexts - of the establishments and their use patterns. This place is one of the main recreation and leisure areas of the city, formed by six kilometres of waterfront, corresponding to a differentiated area through the coast. This space has beach huts with varied profiles: while some more simple huts persist, great complexes are being developed, building even water parks on the beach area. This study analyses relations between:i) spatial configuration (in geometric and mainly topological terms) based on the Social Logic of Space; ii) edified typology (analysing capacity, landscap treatment and program of the huts); and iii) use and environmental perception of the beach by its frequenters. There are consistent relations between the type of hut and their localization in the urban grid, of which were identified groups with different patterns: segregated (north, central and south) and integrated (north: more integrated. and south: less integrated). Such relations also reflect, in varied patterns of use and environmental perception. In spite of their strong economy, the beach huts find themselves in a fragile legal situation because they occupy the beach area, so that this study may come to assist the decision-making for the future of the region. For a sustainable development of the area by those responsible and managers it is necessary to evaluate the cultural importance of the huts at Praia do Futuro, understanding their occupation and uses.

Contributos psicológicos para a compreensão da utilização inapropiada dos serviços de saúde: Estudo exploratório num serviço de urgência

O sobrelotamento dos Serviços de Urgência Pediátrica é uma realidade da sociedade atual, verificando-se uma crescente progressão de atendimentos, principalmente de falsas urgências. Tendo como objetivo identificar fatores psicológicos que possam contribuir para a compreensão da utilização inapropriada destes serviços, foi desenvolvido este estudo exploratório-descritivo. A amostra foi constituída por 115 crianças, observadas sem critérios de urgência num Serviço de Urgência Pediátrica, e respetivos acompanhantes, dos quais 26.1% são emocionalmente perturbados. Os dados, recolhidos através da ficha de urgência, da entrevista e de um questionário, revelaram que a recorrência frequente ao Serviço de Urgência está relacionada com as crenças dos acompanhantes acerca do serviço, com a perceção de criança mais frágil, mais difícil e com mais problemas de comportamento. Conhecidos os efeitos da hospitalização infantil, pretende-se que este estudo abra portas à exploração de novos horizontes, na tentativa de encontrar soluções para a racionalização da utilização dos recursos de saúde. ABSTRACT: The overflow of the Pediatrics Emergencies is a reality in today's society. There has been an increasing attendance, primarily of false emergencies. The objective of this exploratory-descriptive study is to identify the psychological factors that might contribute to the understanding of the inappropriate use of these services. The sample was composed of 115 children, observed without any emergency criterion of the Pediatric Emergency, and respective escorts, of which 26.1% of them are emotionally disturbed. The data gathered through the emergency file, the interview and a questionnaire, revealed that the frequent use of the Emergency Service is related with the beliefs of the escorts, with the perception of a more fragile child, more difficult and with more behavioral problems child. The effects of child hospitalization known, this study intends to open the doors to new horizons, in an attempt to find solutions to the rationalization of the use of health resources.

Estudo sobre as potencialidades de compósitos à base de gesso e fibras de coco seco para aplicação na construção civil

The use of gypsum, one of the oldest building materials for the construction industry in the country has been experiencing a significant and steady growth, due to its low cost and some of its properties that confer comparative advantage over other binder materials. Its use comprises various applications including the coating of walls and the production of internal seals and linings. Moreover, the fibers are being increasingly incorporated into arrays fragile in an attempt to improve the properties of the composite by reducing the number of cracks, the opening of the same and its propagation velocity. Other properties, depending on the function of the component material or construction, among these thermal and acoustic performances, are of great importance in the context of buildings and could be improved, that is, having better performance with this embodiment. Conduct a comparative study of physico-mechanical, thermal and acoustic composite gypsum incorporating dry coconut fiber, in the form of blanket, constituted the main objective of this work. Improving the thermal and acoustic performances of precast gypsum, used for lining and internal vertical fences of buildings, was the purpose of development of these composites. To evaluate the effect of fiber content on the properties of the composites were used to manufacture the composite layer with different thicknesses. The composites were fabricated in the form of plates with dimensions of 500x500x24mm. To facilitate the comparative study of the properties were also made with material gypsum boards only. We then determined the physico-mechanical, thermal and acoustical plaster and composites. The results indicated that the composites were significant gains in relation to thermal performance and also acoustic, in certain frequency range, increasing the thickness of the blanket. Concerning other physical-mechanical properties, the results showed that although the compressive strength was lower than for the composite did not occur after a fracture catastrophic failure. The same trend was observed with regard to resistance to bending, since the composites have not suffered sudden rupture and still continued after the load supporting point of maximum load

Large-scale prediction of seagrass distribution: the case of Cymodocea nodosa (Mediterranean-Atlantic)

Understanding the factors that affect seagrass meadows encompassing their entire range of distribution is challenging yet important for their conservation. We model the environmental niche of Cymodocea nodosa using a combination of environmental variables and landscape metrics to examine factors defining its distribution and find suitable habitats for the species. The most relevant environmental variables defining the distribution of C. nodosa were sea surface temperature (SST) and salinity. We found suitable habitats at SST from 5.8 ºC to 26.4 ºC and salinity ranging from 17.5 to 39.3. Optimal values of mean winter wave height ranged between 1.2 m and 1.5 m, while waves higher than 2.5 m seemed to limit the presence of the species. The influence of nutrients and pH, despite having weight on the models, was not so clear in terms of ranges that confine the distribution of the species. Landscape metrics able to capture variation in the coastline enhanced significantly the accuracy of the models, despite the limitations caused by the scale of the study. By contrasting predictive approaches, we defined the variables affecting the distributional areas that seem unsuitable for C. nodosa as well as those suitable habitats not occupied by the species. These findings are encouraging for its use in future studies on climate-related marine range shifts and meadow restoration projects of these fragile ecosystems.

Os movimentos migratórios para a Europa : Implicações para a Segurança Nacional

Os recentes movimentos migratórios para a Europa decorrentes da atual crise de refugiados é dos temas mais debatidos na atualidade. A instabilidade em países de África e do Médio Oriente, associada a Estados frágeis, cujas instituições deixaram de exercer o efetivo controlo, desenvolvendo-se sob a forma de conflitos armados, muitas vezes fundamentados em radicalismos de natureza étnica, religiosa e ideológica, estão na base das principais causas que provocaram os recentes movimentos migratórios descontrolados e sem precedentes. Estes massivos fluxos migratórios, terão necessariamente repercussões a vários níveis quer sobre as populações deslocadas, quer sobre as comunidades de acolhimento. As migrações atuais adquirem novos contornos, que nos levam a inserir este tema na agenda de investigação dos estudos de segurança. É neste âmbito que surge a investigação intitulada “Os Movimentos Migratórios para a Europa – Implicações para a Segurança Nacional”, que tal como o tema sugere, tem como objetivo primordial apurar quais as principais implicações para a segurança de Portugal, decorrentes dos atuais movimentos migratórios para a Europa, acabando também por propor algumas medidas de nível estratégico e operacional que permitam minorar os impactos na segurança. Assim sendo, a metodologia utilizada nesta investigação tem por base o método de investigação hipotético-dedutivo, que para a validação ou não das respetivas hipóteses formuladas, recorreu-se à realização de entrevistas a entidades que muito têm a dizer sobre esta temática. Conclui-se com a presente investigação que, apesar de Portugal, não fazer parte dos principais destinos desta recente vaga de imigrantes, e de as consequências destes massivos movimentos migratórios não serem fáceis de prever a médio e longo prazo, o nosso país, como parte integrante da UE e signatário do acordo de Schengen, depara-se com um conjunto de ameaças de natureza global, que podendo ser potenciadas por este fenómeno, também podem colocar em causa a nossa segurança.

Cultural Heritage and Mobile Robotics Technologies

This paper reviews current research works at the authors’ Institutions to illustrate how mobile robotics and related technologies can be used to enhance economical fruition, control, protection and social impact of the cultural heritage. Robots allow experiencing on-line, from remote locations, tours at museums, archaeological areas and monuments. These solutions avoid travelling costs, increase beyond actual limits the number of simultaneous visitors, and prevent possible damages that can arise by over-exploitation of fragile environments. The same tools can be used for exploration and monitoring of cultural artifacts located in difficult to reach or dangerous areas. Examples are provided by the use of underwater robots in the exploration of deeply submerged archaeological areas. Besides, technologies commonly employed in robotics can be used to help exploring, monitoring and preserving cultural artifacts. Examples are provided by the development of procedures for data acquisition and mapping and by object recognition and monitoring algorithms.

Espaço público e sociabilidade urbana: apropriações e significados dos espaços públicos na cidade contemporânea

Study public space is studying the city and its dynamics through a representation point. The changes that are observed in these spaces and in the relations established there, or with it, are related to changes that occurred in the city as a whole, in the urban way of living. Study public space allied to urban sociability permits an even better focus on this relation between people in these spaces and with the spaces and in the consequences and fragile aspects this relation can impose to people and cities. This work is aimed towards this relation between public space and urban sociability. Through a conceptual/theoretical discussion aims, specifically, comprehend how to establish and what is the relation between urban space and urban sociability (appropriation/perception of place, tendencies of seclusion), from an isolated analysis of each one of these themes in the contemporaneous city. The Brazilian public space has peculiar characteristics, arising from its historical process of construction, also influenced by the public sphere fragile construction that permeates it, as well as more recent variables such as the sensation of insecurity and commodification of these places. The urban sociability influences and is influenced along all this process of significance and reframing of the public space. The conceptual discussion about each isolate variable provides the necessary coverage for discussion and analysis of the relation between them and the consequence of this relation in the city, such as the notation of relevant experiences of this process of revaluation of the public space. The hereby search is not through a path to reestablish the relation as it already existed, but also for an understanding of the dynamic as is established today and for existing possibilities for maintenance and appreciation of the relation between people and the city by believing in its importance to urban life

Avaliação da qualidade da água do Rio Piranhas-Açu/RN utilizando a comunidade de macroinvertebrados bentônicos

The biomonitoring technique for water quality in water bodies has been incorporated increasingly in management of the natural resources, using mainly indices of its aquatic community characteristics. In Brazil the first efforts to use this technique was restricted to the South and the Midwest region of this country. Located in the northeast region, this study was conducted at Rio Grande do Norte state and had as main objective the assessment of water quality in the Piranhas-Açu river using benthic macroinvertebrates community as biological indicators. Thus, were applied two biotic indices, the BMWP (Biological Monitoring Working Party score system) and the IBF (Family Biotic Index). According the requirements of these indices, two periods of sampling were determined as basic methodology, in dry seasons of 2006 and 2007. The sampling sites were around the municipalities of Açu, Ipanguaçu, Alto do Rodrigues and Pendências. Physical-chemical measurements; a protocol of rapid assessment of diversity of habitats, and determination of the degree of tolerance of each taxon to organic pollution were also performed. The most abundant organisms found in the river were tolerant with the prevalence of Chironomidae (Diptera) and Melanoides tuberculata. This results, together with those ones got in indices application, showed a considerable organic pollution in the four sample places and the reaches were classified as modified to impacted. According to the used indices, this study suggest that this river have significant alteration in the biotic community and water quality on the organic pollution, and this fact, occurs in the reach of the river further downstream, where were expected a good water quality. Considering these results, measures aiming the conservation of this water body are needed regarding as it is inserted into a fragile ecosystem with dry season phenomenon, and the water of this river has extremely importance for the local economy
