O tratamento cartográfico da informação em saúde do trabalhador

Apesar do reconhecimento da importância dos conhecimentos geográficos e do uso das ferramentas de análise espacial nos estudos da saúde coletiva, esse é um campo ainda pouco explorado pelos pesquisadores brasileiros. em levantamento realizado nas principais revistas científicas que veiculam os resultados de pesquisa em saúde do trabalhador, verificou-se o grande predomínio do uso de tabelas e gráficos como meio de organizar e apresentar os resultados obtidos, e o número reduzido de mapas. Para isso foram examinados todos os artigos publicados em quatro periódicos (Revista de Saúde Pública, Cadernos de Saúde Pública, Revista Saúde e Sociedade e Revista Brasileira de Epidemiologia) no período de 1967 a 2009. Uma vez analisado o conjunto de artigos selecionados no estudo, aqueles que utilizaram representações cartográficas receberam atenção especial. Verificou-se que, embora ainda pouco utilizadas, as ferramentas do geoprocessamento e da geoestatística com suporte em SIG abrem um campo de novas possibilidades no uso da cartografia temática em saúde do trabalhador no Brasil. Contudo, recomenda-se para os editores das revistas científicas o detalhamento de normas técnicas para publicação de figuras cartográficas, assim como a elaboração de pareceres específicos que possam auxiliar os autores em vista das modificações necessárias para a melhoria da qualidade da comunicação visual de mapas e da correlação espacial por meio do tratamento cartográfico.

Cartografia temática do atlas de sensibilidade ambiental a derramamentos de óleo do litoral paulista

The objective of this paper is the elaboration and implementation of procedures in a cartographic representation related by fundamental of thematic cartography and graphic semiology for the standardization of the Environmental Oil Spill Sensitivity Maps supported by a Geographic Information Systems (GIS) for handling and modeling of a large number of variables. These make up the Environmental Sensitivity Atlas to Oil Spills in Coastal Paulista, and that represents the phenomena that occur in geographic space accurately so as to highlight the importance of each element in the evaluation and protection of areas of greater sensitivity oil. The composition of the cartographic documents considers the Littoral Sensitivity Index (LSI), biological resources and the resources for human use that could be negatively impacted. Thus, the information contained in each map was carefully evaluated before implementation, so that the cartographic representations of various resources, environments, and other ISLs, the reader should issue an immediate message that could be understood clearly, without requiring prior knowledge of specialized. Another aspect was the distribution harmoniously all the elements contained in the document, so that information could be enough without overwhelming it. It was also taken a certain care, so each symbol could be used properly in order that there is no conflict in the information.

Evaluación del ruido ambiental en espacios naturales protegidos: implicaciones para su gestión

Esta Tesis Doctoral trata sobre la caracterización acústica de los ecosistemas naturales y la evaluación del impacto ambiental del ruido antropogénico sobre sus potenciales receptores en estos lugares, incluidos los receptores no humanos y sus efectos ecológicos, además, analiza las implicaciones para su gestión a distintas escalas y se lleva a cabo una valoración económica. Este trabajo ofrece soluciones para caracterizar los paisajes sonoros de forma compatible con distintas escalas de trabajo, nivel de esfuerzo técnico y en contextos de recursos limitados que haga viable su tratamiento como cualquier otra variable ambiental en el ámbito de la conservación y gestión del medio natural. Se han adaptado herramientas y metodologías propias de disciplinas como la acústica ambiental, bioacústica y ecología del paisaje, para servir a los objetivos específicos de la evaluación y gestión de los paisajes sonoros y el ruido ambiental en amplias extensiones geográficas. Se ha establecido un método general de muestreo sistemático para trabajo de campo y también se han adaptado métodos de modelización informática, que permiten analizar escenarios sonoros dinámicos en el tiempo y en el espacio, desde localizaciones puntuales hasta la escala del paisaje. Es posible elaborar cartografía ambiental con esta información y se ha representado gráficamente la zona de influencia de distintas fuentes de ruido sobre la calidad de distintos hábitats faunísticos. Se recomienda el uso del indicador del nivel de presión sonora equivalente (Leq) por su operatividad en medición y modelización, y su adaptabilidad a cualquier dimensión espacial y temporal que se requiera, por ejemplo en función del paisaje, actividades o especies que se establezcan como objeto de análisis. Se ha comprobado que las voces y conversaciones de parte de los excursionistas en zonas de reposo, observación y descanso (Laguna Grande de Peñalara) es la fuente de ruido que con mayor frecuencia identifican los propios visitantes (51%) y causa un incremento del nivel de presión sonora equivalente de unos 4,5 dBA sobre el nivel correspondiente al ambiente natural (Lnat). También se ha comprobado que carreteras con bajo nivel de tráfico (IMD<1000) pueden causar estrés fisiológico sobre la fauna y afectar a la calidad de sus hábitats. La isófona de 30 dBA del índice Leq (24h) permite dividir a los corzos de la zona de estudio en dos grupos con diferente nivel de estrés fisiológico, más elevado en los que se sitúan más cerca de la carretera con mayor volumen de tráfico y se expone a mayores niveles de ruido. Por otro lado, ha sido posible delimitar una zona de exclusión para la nidificación de buitre negro alrededor de las carreteras, coincidente con la isófona Leq (24h) de 40 dBA que afecta al 11% de su hábitat potencial. Además se ha llevado a cabo una novedosa valoración económica de la contaminación acústica en espacios naturales protegidos, mediante el análisis de la experiencia sonora de los visitantes del antiguo Parque Natural de Peñalara, y se ha constatado su disposición al pago de una entrada de acceso a estos lugares (aproximadamente 1 euro) si redundara en una mejora de su estado de conservación. En conclusión, los espacios naturales protegidos pueden sufrir un impacto ambiental significativo causado por fuentes de ruido localizadas en su interior pero también lejanas a ellos, que se sitúan fuera del ámbito de competencias de sus gestores. Sucesos sonoros como el sobrevuelo de aviones pueden incrementar en aproximadamente 8 dBA el nivel de referencia Lnat en las zonas tranquilas del parque. Se recomienda llevar a cabo una gestión activa del medio ambiente sonoro y se considera necesario extender la investigación sobre los efectos ecológicos del ruido ambiental a otros lugares y especies animales. ABSTRACT This PhD Thesis deals with acoustic characterization of natural ecosystems and anthropogenic noise impact assessment on potential receivers, including non-human receivers and their ecological effects. Besides, its management implications at different scales are analyzed and an economic valuation is performed. This study provides solutions for characterizing soundscapes in a compatible way with different working scales, level of technical effort and in a context of limited resources, so its treatment becomes feasible as for any other environmental variable in conservation and environmental management. Several tools and methodologies have been adapted from a variety of disciplines such as environmental acoustics, bioacoustics and landscape ecology, to better serve the specific goals of assessing and managing soundscapes and environmental noise in large areas. A procedure has been established for systematic field measurement surveys and noise common computer modelling methods have also been adapted in order to analyze dynamic soundscapes across time and space, from local to landscape scales. It is possible to create specific thematic cartography as for instance delimiting potential influence zone from different noise sources on animal habitats quality. Use of equivalent continuous sound pressure level index (Leq) is recommended because it provides great flexibility in operation for noise measurement and modelling, and because of its adaptability to any required temporal and spatial dimension, for instance landscape, activities or the target species established as study subjects. It has been found that human voices and conversations in a resting and contemplation area (Laguna Grande de Peñalara) is the most frequently referred noise source by national park visitors (51 %) when asked. Human voices alter this recreational area by increasing the sound pressure level approximately 4.5 dBA over the natural ambient level (Lnat). It has also been found that low traffic roads (AADT<1000 ) may cause physiological stress on wildlife and affect the quality of their habitats. It has also been possible to define a road-effect zone by noise mapping, which suggests an effective habitat loss within the Leq (24h) 30 dBA isophone in case of Roe deer and also divide the study area in two groups with different physiological stress level, higher for those exposed to higher noise levels and traffic volume. On the other hand, it has been possible to determine an exclusion area for Cinereous vulture nesting surrounding roads which is coincident with the Leq (24h) 40 dBA isophone and affects 11 % of the vulture potential habitat. It has also been performed an economic estimation of noise pollution impact on visitors’ perception and results showed that visitors would be willing to pay an entrance fee of approximately 1 euro if such payment is really bringing an improvement of the conservation status. In conclusion, protected areas may be significantly affected by anthropogenic noise sources located within the park borders but perturbations may also be caused by large-distance noise sources outside the park managers’ jurisdiction. Aircraft overflight events disrupted quietness and caused Leq increases of almost 8 dBA during a monitoring period with respect to Lnat reference levels in the park quiet areas. It is recommended to actively manage the acoustic environment. Finally, further research on ecological impacts of environmental noise needs to be extended to other species and places.

Análise da paisagem e das alterações de uso/ocupação do solo no Lubango e arredores

A cartografia temática surge como um aliado indispensável ao estudo e conhecimento do estado da paisagem e dos ecossistemas terrestres. Angola é um país com uma enorme lacuna em termos de informação cartográfica para suporte a diversas actividades desenvolvidas em várias áreas. É por isso necessária informação sobre a superfície terrestre que registe as alterações temporais ocorridas nos ecossistemas e identifique os factores que estão na sua origem de forma a implementar medidas que permitam uma gestão mais sustentável do seu enorme território. O presente estudo foi realizado no sector Sudoeste de Angola, abrangendo os municípios do Lubango, Humpata e Chibia, com uma área aproximada de 9600 km2. Os objectivos foram: a) cartografar o coberto do solo e monitorizar as alterações ocorridas na área de estudo no período 1990-2010, b) analisar e interpretar as alterações da estrutura da paisagem nos últimos 20 anos usando cartografia de ocupação do solo, produzida recorrendo a imagens de satélite, e métricas da paisagem, e c) quantificar e examinar a relação entre a fragmentação da paisagem e os factores geradores. A metodologia utilizada no estudo é composta por duas partes, sendo a primeira dedicada às operações de processamento e interpretação de imagens de satélite Landsat e, a segunda dedicada à produção de novas métricas de fragmentação da paisagem com recurso à ferramenta SIG utilizando operações de álgebra de mapas. O comportamento da fragmentação é analisado, à luz do efeito dos fatores ambientais e socioeconómicas ao nível da região. Os resultados obtidos, através da aplicação de técnicas de deteção remota e usando imagens Landsat TM e ETM+, permitiram a elaboração de mapas de coberto do solo, onde se distinguiram 8 classes temáticas e espectralmente diferentes. Verificou-se em termos globais que aproximadamente 38% da área sofreu algum tipo de alteração no período estudado, sendo as classes de miombo e áreas cultivadas as que mais alterações sofreram. A fragmentação da paisagem foi avaliada através da implementação de novas métricas, mostrando os resultados, que no período 1990-2000, a fragmentação foi superior à que se verificou entre 2000-2010. A nível espacial, a dinâmica de fragmentação foi mais acentuada, entre 1990-2000, na Humpata e, entre 2000-2010, no Lubango; ANALYSIS OF LANDSCAPE AND LAND USE LAND COVER CHANGE IN LUBANGO AND SURROUNDINGS ABSTRACT: Thematic cartography shows up as an essential ally in the study and knowledge of the state of landscapes and terrestrial ecosystems. Angola is a country with an enormous lack of cartographic information to support the several activities carried out in a variety of areas. This is the reason information on the earth’s surface is necessary, registering alterations which occur over time in ecosystems and identifying the associated factors in its origin, so as to implement metrics that allow a more sustainable management of its enormous territory. This study was carried out in the Southeast of Angola in the Lubango, Humpata and Chibia Municipalities, with an area of approximately 9600 km2. Our objectives were the following: a) land cover mapping and land cover changes monitoring over the period 1990 to 2010 using Landsat images, b) to analyze and interpret landscape structures changes using land cover maps, and landscapes metrics, and c) to quantify and to examine the relationship between landscape fragmentation and its drivers. The methodology developed in the study has two parts, the first includes Landsat satellite images processing and interpretation and, the second the production of new landscape fragmentation metrics with support to a GIS tool and algebraic mapping operations. The fragmentation behavior is analyzed, taking into account the effect of environmental and socioeconomic factors at a regional level. The results allowed obtaining land cover maps, in which 8 spectrally different thematic classes were distinguished. It was observed that 38% of the area suffered some type of alteration in the studied period, with higher changes observed in the classes of miombo and agriculture. Landscapes fragmentation results, evaluated through the implementation of new metrics, show that, values are greater in the period 1990-2000 than in 2000-2010. At municipality level, fragmentation dynamics were more accentuated in Humpata between 1990 -2000 and in Lubango between 2000 -2010.

Software Cartography: Thematic Software Visualization with Consistent Layout

Software visualizations can provide a concise overview of a complex software system. Unfortunately, as software has no physical shape, there is no `natural' mapping of software to a two-dimensional space. As a consequence most visualizations tend to use a layout in which position and distance have no meaning, and consequently layout typically diverges from one visualization to another. We propose an approach to consistent layout for software visualization, called Software Cartography, in which the position of a software artifact reflects its vocabulary, and distance corresponds to similarity of vocabulary. We use Latent Semantic Indexing (LSI) to map software artifacts to a vector space, and then use Multidimensional Scaling (MDS) to map this vector space down to two dimensions. The resulting consistent layout allows us to develop a variety of thematic software maps that express very different aspects of software while making it easy to compare them. The approach is especially suitable for comparing views of evolving software, as the vocabulary of software artifacts tends to be stable over time. We present a prototype implementation of Software Cartography, and illustrate its use with practical examples from numerous open-source case studies.

Curriculum mapping of the Spatial Science Program, QUT : what was the cartography journey?

There are currently a number of issues of great importance affecting universities and the way in which their programs are now offered. Many issues are largely being driven top-down and impact both at a university-wide and at an individual discipline level. This paper provides a brief history of cartography and digital mapping education at the Queensland University of Technology (QUT). It also provides an overview of what is curriculum mapping and presents some interesting findings from the program review process. Further, this review process has triggered discussion and action for the review, mapping and embedding of graduate attributes within the spatial science major program. Some form of practical based learning is expected in vocationally oriented degrees that lead to professional accreditation and are generally regarded as a good learning exposure. With the restructure of academic programs across the Faculty of Built Environment and Engineering in 2006, spatial science and surveying students now undertake a formal work integrated learning unit. There is little doubt that students acquire the skills of their discipline (mapping science, spatial) by being immersed in the industry culture- learning how to process information and solve real-world problems within context. The broad theme of where geo-spatial mapping skills are embedded in this broad-based tertiary education course are examined with some focused discussion on the learning objectives, outcomes and examples of some student learning experiences

Innovative cartography standards for Web-GIS portals : case study of the 'Survey of Israel's' Web-GIS Portal

Maps have been published on the world wide web since its inception (Cartwright, 1999) and are still accessed and viewed by millions of users today (Peterson, 2003). While early webbased GIS products lacked a complete set of cartographic capabilities, the functionality within such systems has significantly increased over recent years. Functionalities once found only in desktop GIS products are now available in web-based GIS applications, for example, data entry, basic editing, and analysis. Applications based on web-GIS are becoming more widespread and the web-based GIS environment is replacing the traditional desktop GIS platforms in many organizations. Therefore, development of a new cartographic method for web-based GIS is vital. The broad aim of this project is to examine and discuss the challenges and opportunities of innovative cartography methods for web-based GIS platforms. The work introduces a recently developed cartographic methodology, which is based on a web-based GIS portal by the Survey of Israel (SOI). The work discusses the prospects and constraints of such methods in improving web-GIS interfaces and usability for the end user. The work also tables the preliminary findings of the initial implementation of the web-based GIS cartographic method within the portal of the Survey of Israel, as well as the applicability of those methods elsewhere.

A thematic approach to integrating maths and science for pre-service primary teachers via sustainability

Efforts to improve mathematics and science content knowledge have in many institutions required redefining teacher education through new teaching and learning. See, for example, Peard & Pumadevi (2007) for an account of one such attempt involving the development of a Foundations Unit, Scientific and Quantitative Literacy. This unit is core for all first year pre-service primary teacher education students at Queensland University of Technology (QUT) and two Education Institutes in Malaysia, Institute Perguruan Raja Melewar (IPRM), and Institute Perguruan Teknik (IPT) Kuala Lumpur. Since then, QUT has modified the unit to adopt a thematic approach to the same content. An aim of the unit rewrite was the development of a positive attitude and disposition to the teaching and learning of mathematics and science, with a curiosity and willingness to speculate about and explore the world. Numeracy was specifically identified within the mathematics encountered and appropriately embedded in the science learning area. The importance of the ability to engage in communication of and about mathematics and science was considered crucial to the development of pre-service primary teachers. Cognisance was given to the appropriate selection and use of technology to enhance learning - digital technologies were embedded in the teaching, learning and assessment of the unit to avoid being considered as an optional extra. This was achieved around the theme of “the sustainable school”. This „sustainability‟ theme was selected due to its prominence in Australia‟s futures-oriented National Curriculum which will be implemented in 2011. This paper outlines the approach taken to the implementation of the unit and discusses early indicators of its effectiveness.
