Aplicação de SIG no Processamento do Inventário Florestal Nacional – Cabo Verde

Cabo Verde desde do século passado tem envidado esforço na florestação, sobretudo depois de 1975 para atenuar os efeitos da seca e da desertificação criando deste modo grandes áreas arborizadas. Entretanto, à medida que os recursos florestais foram sendo criados, a problemática da sua avaliação e da sua gestão sustentável, passaram a merecer maior atenção das autoridades nacionais. A lei florestal, promulgada em 1998 define como uma das atribuições e acções do Estado, através dos serviços florestais, a elaboração dos planos de gestão das zonas florestais. Este plano de gestão implica a análise e a apreciação de dados concretos e actualizados sobre a situação real das zonas florestais, sendo possível apenas através do inventário florestal nacional (IFN). Neste trabalho é proposta uma metodologia de processamento do IFN em que se utilizam as potencialidades dos Sistemas de Informação Geográfica (SIG). Foram utilizados para este trabalho os programas: ArcGis 9.1, para produção cartográfica, geoprocessamento e análise espacial e o Field-Map 8.1 para a classificação de ortofotos num esquema de classificação hierárquica, em cinco níveis, adaptado a Cabo Verde (classes de uso do solo adoptado ao esquema de classificação do território europeu – CORINE Land Cover e da Organização das Nações Unidas para a Agricultura e Alimentação (FAO). Os dados utilizados foram compilados no âmbito do projecto do inventário florestal. Os resultados obtidos, para a Ilha de Santiago, constituem uma base cartográfica para o IFN com diversos temas cartográficos, nomeadamente, mapas das zonas florestadas, mapas de ocupação do solo e mapas de amostras inventariáveis cuja metodologia de elaboração poderá ser facilmente replicada para as restantes ilhas do arquipélago.

Survey on batch-to-batch variation in spray paints: a collaborative study

This study represents the most extensive analysis of batch-to-batch variations in spray paint samples to date. The survey was performed as a collaborative project of the ENFSI (European Network of Forensic Science Institutes) Paint and Glass Working Group (EPG) and involved 11 laboratories. Several studies have already shown that paint samples of similar color but from different manufacturers can usually be differentiated using an appropriate analytical sequence. The discrimination of paints from the same manufacturer and color (batch-to-batch variations) is of great interest and these data are seldom found in the literature. This survey concerns the analysis of batches from different color groups (white, papaya (special shade of orange), red and black) with a wide range of analytical techniques and leads to the following conclusions. Colored batch samples are more likely to be differentiated since their pigment composition is more complex (pigment mixtures, added pigments) and therefore subject to variations. These variations may occur during the paint production but may also occur when checking the paint shade in quality control processes. For these samples, techniques aimed at color/pigment(s) characterization (optical microscopy, microspectrophotometry (MSP), Raman spectroscopy) provide better discrimination than techniques aimed at the organic (binder) or inorganic composition (fourier transform infrared spectroscopy (FTIR) or elemental analysis (SEM - scanning electron microscopy and XRF - X-ray fluorescence)). White samples contain mainly titanium dioxide as a pigment and the main differentiation is based on the binder composition (Csingle bondH stretches) detected either by FTIR or Raman. The inorganic composition (elemental analysis) also provides some discrimination. Black samples contain mainly carbon black as a pigment and are problematic with most of the spectroscopic techniques. In this case, pyrolysis-GC/MS represents the best technique to detect differences. Globally, Py-GC/MS may show a high potential of discrimination on all samples but the results are highly dependent on the specific instrumental conditions used. Finally, the discrimination of samples when data was interpreted visually as compared to statistically using principal component analysis (PCA) yielded very similar results. PCA increases sensitivity and could perform better on specific samples, but one first has to ensure that all non-informative variation (baseline deviation) is eliminated by applying correct pre-treatments. Statistical treatments can be used on a large data set and, when combined with an expert's opinion, will provide more objective criteria for decision making.

How many diagnosis fields are needed to capture safety events in administrative data? Findings and recommendations from the WHO ICD-11 Topic Advisory Group on Quality and Safety

OBJECTIVE: As part of the WHO ICD-11 development initiative, the Topic Advisory Group on Quality and Safety explores meta-features of morbidity data sets, such as the optimal number of secondary diagnosis fields. DESIGN: The Health Care Quality Indicators Project of the Organization for Economic Co-Operation and Development collected Patient Safety Indicator (PSI) information from administrative hospital data of 19-20 countries in 2009 and 2011. We investigated whether three countries that expanded their data systems to include more secondary diagnosis fields showed increased PSI rates compared with six countries that did not. Furthermore, administrative hospital data from six of these countries and two American states, California (2011) and Florida (2010), were analysed for distributions of coded patient safety events across diagnosis fields. RESULTS: Among the participating countries, increasing the number of diagnosis fields was not associated with any overall increase in PSI rates. However, high proportions of PSI-related diagnoses appeared beyond the sixth secondary diagnosis field. The distribution of three PSI-related ICD codes was similar in California and Florida: 89-90% of central venous catheter infections and 97-99% of retained foreign bodies and accidental punctures or lacerations were captured within 15 secondary diagnosis fields. CONCLUSIONS: Six to nine secondary diagnosis fields are inadequate for comparing complication rates using hospital administrative data; at least 15 (and perhaps more with ICD-11) are recommended to fully characterize clinical outcomes. Increasing the number of fields should improve the international and intra-national comparability of data for epidemiologic and health services research, utilization analyses and quality of care assessment.

Geoheritage popularisation and cartographic visualisation in the Tsanfleuron-Sanetsch area (Valais, Switzerland)

This paper presents the underlying concepts developed by the Institute of Geography of the University of Lausanne (Switzerland) for a popularisation project of the geoheritage in the Tsanfleuron-Sanetsch area (Valais, Switzerland). Due to its wide scientific interest, the local geoheritage is of great value (Reynard, 2008). The article details the complementary links existing between the different parts of a geotourist project - databases, educational panels, educational material and geotourist map - developed for popularising the geoheritage value of the area. Each element of the project is briefly presented. Special focus is set on mapping questions: how cartographic design and information structure can be set in order to facilitate map's use and comprehension. In this way, the Tsanfleuron-Sanetsch map is presented as an applied example of the guiding principles proposed by Coratza and Regolini-Bissig (2009).

Análisis de viabilidad técnica-económica del parque eólico Altos de Peralta

RESUMEN La energia eolica se considera una forma indirecta de energia solar. Entre el 1 y 2% de la energia proveniente del sol se convierte en viento, debido al movimiento del aire ocasionado por el desigual calentamiento de la superficie terrestre. La energia cinetica del viento puede transformarse en energia util, tanto mecanica como electrica. La energia eolica, transformada en energia mecanica ha sido historicamente aprovechada, pero su uso para la generacion de energia electrica es mas reciente, en respuesta a la crisis del petroleo y a los impactos ambientales derivados del uso de combustibles. El objetivo principal de este trabajo es hacer un analisis de viabilidad desde un punto de vista tecnico y economico de un parque eolico situado en el municipio de Barasoain (Navarra). Desde el punto de vista tecnico se han estudiado los aspectos constructivos del parque considerando sus diferentes infraestructuras de obra civil y electrica asi como los niveles de recurso eolico. En el ambito economico y financiero se han analizado los aspectos y ratios mas relevantes que definen un proyecto de estas caracteristicas asi como el modelo de financiacion elegida basada en el Project- Finance. Entre las conclusiones mas destacadas de este proyecto cabe destacar la contribucion de la construccion del parque al desarrollo social y economico de la zona donde queda ubicado contribuyendo a la creacion de puestos de trabajo, tanto en la fase de construccion como de explotacion y una perfecta armonia con condicionantes medioambientales de la zona. El analisis tecnico realizado nos indica la viabilidad tecnica del parque tanto desde el punto de vista de recurso eolico como la idoneidad para poder evacuar la energia producida. Por otro lado, los resultados obtenidos cumplen perfectamente con los estandares requeridos por los financiadores de los parques y resultando ser muy atractivos para sus accionistas

Aplicación de realidad aumentada para dispositivos móviles destinada a espacios culturales. Ejemplo de desarrollo: Museu Episcopal de Vic

Proyecto de aplicación para dispositivos móviles que utiliza la Realidad Aumentada (RA) para contextualizar obras artísticas. Es un producto pensado para museos y galerías pero también para espacios exteriores que posean elementos de valor cultural. Sin embargo, y para servir de ejemplo se ha aplicado en seis piezas destacadas del Museo Episcopal de Vic. Aunque en Europa y EE.UU. los museos ya están innovando en este terreno, en España, que es donde se enmarca el proyecto, existe una carencia de elementos de mediación cultural como estos; sobre todo en los museos de arte donde las obras acostumbran a presentarse despojadas de cualquier herramienta que proporcione información complementaria. Existe, por tanto, una descontextualización del arte que crea barreras para el entendimiento del público general. De esta situación de carencia parte el objetivo principal del producto, el de aprovechar las posibilidades de la RA para mejorar la experiencia y el diálogo entre el visitante y la obra, aportando conocimiento y fomentando el aprendizaje.

IDENTITÉ, PROJET, CHANGEMENT : DES REPRÉSENTATIONS SOCIALES AUX LEVIERS DE L'ACTION PUBLIQUE. POUR UN MODE DE GOUVERNANCE AXÉ SUR LE DÉVELOPPEMENT TERRITORIAL. ETUDE DE CAS : CANTON DU JURA (SUISSE)

Thirty years after the Canton of Jura entered sovereignty, it has to be admited that the creation of the newly canton did't fullfill the hopes of economic and demografic growth that many could have expected from political independance. Through a plurality of complementary approaches, the research suggest a closer look at, on one hand, the position of the Canton in its territorial context as well as its structure and dynamics and on the other hand, the representations of the territory and its evolution by the social actors. This in order to formulate a set of social demands (of debate, of openness and of overcoming cleavages) which augurs for a new territoriality regime and testify of a requirement of reflexivity toward the state institutions and actions. The analysis allowed to set in evidence the central role of the couple identity-project in the dynamics of change, and to identifiy three main periods in the recent past of the Canton: a period of territorialization, during which grew a strong collective identity, coupled with a major project of society (the creation of the canton of Jura); then followed a period of deterritorialization, with the fragmentation of the collective identity and the lack of a project of society. Then, the third period, with a paradoxical event, the failure in public vote of the the project Jura open Land (Jura Pays ouvert), which was meant to give a second wind to the Canton. We consider this turning point as the start of a new period (of reterritorialization), with an issue linked with the outlines of a renewed "jurassian" identity and the elaboration of a shared territory project.Trente ans après l'entrée en souveraineté, force est de constater que la création du canton du Jura n'a pas permis de répondre aux espérances de développement économique et démographique que l'indépendance politique devait entraîner dans son sillage. Cette recherche se propose, à travers une pluralité d'approches complémentaires, d'examiner d'une part la position du Canton dans son contexte territorial ainsi que sa structure et sa dynamique; d'autre part, les représentations que se font les acteurs du territoire et de son évolution, pour déboucher sur une série de demandes sociales (de débat, d'ouverture et de dépassement des clivages) qui augurent de la transition vers un nouveau régime de territorialité et témoignent d'une exigence de réflexivité envers les institutions et les actions de l'Etat. L'analyse a permis de mettre en évidence le rôle central du couple identité-projet dans la dynamique de changement et d'identifier trois temps forts dans l'évolution récente du Canton, une phase de territorialisation au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase de déterritorialisation avec une fragmentation de l'identité collective et l'absence de projet mobilisateur. Enfin, un moment paradoxal, l'échec du projet Jura Pays ouvert, censé redonner un second souffle au Canton, qui amorce une nouvelle étape (de reterritorialisation) avec un questionnement lié aux contours d'une identité jurassienne renouvelée et à l'élaboration d'un projet de territoire partagé.Les ressorts de la production du territoire et de son développement sont analysés à travers le rôle des représentations sociales dans la constitution identitaire et le projet territorial, à l'exemple du canton du Jura.

Une première phase (la création du canton du Jura), au cours de laquelle s'est constituée une identité forte doublée d'un projet de société majeur, suivie d'une phase au cours de laquelle l'identité collective s'est fragmentée en l'absence de projet mobilisateur (la phase de « gestion » de l'Etat). Puis un moment de rupture (l'échec du projet Jura Pays ouvert) et l'amorce d'une transition vers une nouvelle étape, avec un questionnement lié aux contours d'une identité jurassienne renouvelée, à l'élaboration d'un projet de territoire partagé, et à l'action des pouvoirs publics dans un contexte de repositionnement du Canton.
