Os processos ecológicos contribuem de forma ímpar para vivência humana, sendo capazes de fornecer condições essenciais à manutenção da vida na Terra, permitindo que ecossistemas se mantenham em equilíbrio. Nesse cenário, algumas áreas designadas legalmente pelo poder público, incubem-se de proteger vestígios naturais às ações antrópicas, porém estas áreas protegidas vêm sofrendo continuamente com pressões humanas mesmo em seus interiores. Assim, o Parque Estadual da Ilha Anchieta (PEIA), localizado no litoral norte do estado de São Paulo, é uma das áreas protegidas mais visitadas do estado. Nesse contexto, diversas atividades recreativas são permitidas em seu interior, possibilitando assim possíveis adversidades aos processos ecológicos. Assim, o objetivo deste trabalho foi avaliar a qualidade visual da paisagem do PEIA, por meio de indicadores ambientais. Para tal, foram selecionadas 10 paisagens de alta relevância quanto a sua beleza cênica, fluxo de turistas, amplitude visual, relevância educacional e para a conservação ambiental. As paisagens encontram-se em diferentes altitudes, fitofisionomias, aspectos abióticos e níveis de acesso público, com diversidade espacial, o que confere características únicas a elas. Os seguintes indicadores visuais foram usados na classificação das paisagens: diversidade; naturalidade; singularidade e detratores. Além disso, os locais foram georreferenciados e fotografados. Como resultado, quatro locais apresentaram qualidade visual média; quatro, com qualidade visual média superior e duas paisagens com qualidade visual superior. Em geral, a qualidade visual foi inferior nas zonas frontais do PEIA, onde o acesso aos turistas é facilitado por trilhas e infraestrutura de apoio. Já regiões mais afastadas e de difícil acesso foram as que apresentaram melhor qualidade visual. Deste modo, conclui-se que de fato a interferência humana reflete diretamente na qualidade visual das paisagens e assim, medidas de gestão ambiental, principalmente a atualização do seu plano de manejo, que data de 1989, podem dar suporte a uma proteção mais qualificada ao parque, bem como, proporcionar uma experiência ainda mais agradável e educativa aos seus visitantes. Quality visual landscape of State Park Anchieta Island, Ubatuba (SP, Brazil) ABSTRACT The ecological processes contribute in a unique way to human experience, being able to provide essential conditions for sustaining life on earth, allowing that keep ecosystems in balance. In this scenario, some areas legally designated by the Government, incubate up to protect natural traces to human actions, but these protected areas are continuously suffering from human pressures even in their interiors, Thus, the State Park of the Anchieta Island (PEIA), located on the northern coast of São Paulo, is one of the most visited protected areas of the state. In this context, various recreational activities are allowed inside, thus enabling possible adversities to ecological processes. Thus, the aim of this study was to evaluate the visual quality of PEIA landscape through environmental indicators. To this end, were selected 10 landscapes of high relevance as its scenic beauty, tourist flow, visual range, educational relevance and to environmental conservation. The landscapes are at different altitudes, vegetation types, abiotic aspects and public access levels with spatial diversity, which gives unique characteristics to them. The following visual indicators were used in the classification of landscapes: diversity; naturalness; uniqueness and detractors. Furthermore, the sites were georeferenced and photographed. As result, four sites had visual medium quality; four, with visual medium superior quality and two landscapes with visual superior quality. In general, the visual quality was lower in the frontal areas of the PEIA, where access to tourists is facilitated by trails and infrastructure support. Already more remote areas and difficult access showed the best visual quality. Thus, it is concluded that in fact human interference directly reflects the visual quality of the landscape and thus environmental management measures, mainly updating its management plan, dating from 1989 can support a more qualified protection park, as well as provide an experience even more enjoyable and educational visitors. KEYWORDS: Ecotourism; Protected Areas; Environmental Indicators.

Abstract:CBT (computer-based training) applications and hypermedia publications are two different approaches to the utilisation of computers in medical education.Medical CBT software continues to playa minor role in spite of the increasing availability, whereas hypermedia have become very popular through the World Wide Web (WWW). Based on the HTML format they can be designed by non-programmers using inexpensive tools while the production of CBT applications requires programming expertise. HTML documents can be easily developed to be distributed by a web-server or to run as local applications.In developed countries CBT and hypermedia have to compete with an abundance of printed or audio-visual media and a wealth of lectures, conferences, etc., whereas in developing countries these media are scarce and expensive. Here CBT programs, and hypermedia publications in particular, may be a cost-effective way to improve quality of education in the health sector.

The blind and visually impaired people are facing a number of challenges in their daily life. One of the major challenges is finding their way both indoor and outdoor. For this reason, routing and navigation independently, especially in urban areas are important for the blind. Most of the blind undertake route finding and navigation with the help of a guide. In addition, other tools such as a cane, guide dog or electronic aids are used by the blind. However, in some cases these aids are not efficient enough in a wayfinding around obstacles and dangerous areas for the blind. As a result, the need to develop effective methods as decision support using a non-visual media is leading to improve quality of life for the blind through their increased mobility and independence. In this study, we designed and implemented an outdoor mobile sensor-based wayfinding system for the blind. The objectives of this study are to guide the blind for the obstacle recognition and the design and implementation of a wayfinding and navigation mobile sensor system for them. <br><br> In this study an ultrasonic sensor is used to detect obstacles and GPS is employed for positioning and navigation in the wayfinding. This type of ultrasonic sensor measures the interval between sending waves and receiving the echo signals with respect to the speed of sound in the environment to estimate the distance to the obstacles. In this study the coordinates and characteristics of all the obstacles in the study area are already stored in a GIS database. All of these obstacles were labeled on the map. The ultrasonic sensor designed and constructed in this study has the ability to detect the obstacles in a distance of 2cm to 400cm. The implementation and the results obtained from the interview of a number of blind persons who employed the sensor verified that the designed mobile sensor system for wayfinding was very satisfactory.
