Vulnerability and health problems while traveling: the viewpoint of the tourist in the city of Rio de Janeiro

Este artigo analisa como um grupo de turistas compreende a questão da saúde em viagem segundo aspectos de segurança, prevenção e busca de atendimento de saúde. Foram entrevistados turistas brasileiros visitando a cidade do Rio de Janeiro e cariocas saindo de viagem. Os depoimentos foram analisados segundo as dimensões de vulnerabilidade; informação; prevenção e assistência em saúde, das quais a vulnerabilidade emergiu como categoria de análise. O relato das trajetórias dos turistas permitiu identificar nós e percursos que poderiam ser utilizados pelo setor saúde para ações de prevenção e promoção. O meio de transporte condiciona o trajeto dos turistas e suas alternativas de atenção. A viagem em grupo e para locais conhecidos foram destacadas como fatores de proteção, o que reforça o papel da informação e de redes de apoio social como recursos utilizados pelos turistas na ausência de políticas específicas voltadas para estes grupos populacionais de grande mobilidade e vulnerabilidade.This article examines how a group of tourists perceives health issues related to safety, prevention and health care during their travels. Interviews were conducted with Brazilian tourists visiting the city of Rio de Janeiro, as well as local residents leaving the city on trips. The interviews were analyzed in accordance with the dimensions of vulnerability, information, prevention and health care, from which vulnerability emerged as a category of analysis. The reports of the trajectory of the tourists made it possible to identify problems and opportunities that could be used by the health sector for actions of prevention and promotion. The means of transport determines the trajectory of tourists and their security alternatives. Traveling in groups and visiting tourist attractions are seen as protective factors, which reinforces the role of information and social support networks as resources used by tourists in the absence of specific policies geared to this highly mobile and vulnerable population group.Fundação Oswaldo CruzCNPqEsse estudo é parte da tese intitulada "A saúde do\ud viajante na visão de três atores: gestores da saúde\ud pública, gestores do turismo e o turista

Littré's hernia

Littré's hernia is an extremely rare surgical event. It is characterized by the presence of Meckel's diverticulum in the hernial sack. The authors report one case of Littré's hernia in a 42 year-old male who had the diagnosis accomplished in the intraoperative. The diverticulum presented no signs of complications and was treated conservatively , without exeresis.Universidade Federal de AlagoasUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Programa de Pós - Graduação em Gastroenterologia CirúrgicaUNIFESP, EPM, Programa de Pós - Graduação em Gastroenterologia CirúrgicaSciEL

Observational study of the power relationships in the movie Lorenzo's Oil

A proposta deste artigo é analisar as relações de poder presentes no filme O óleo de Lorenzo, que se baseia numa história real, mais ainda em construção. O trabalho toma como base argumentativa o estudo de Bourdieu (1993) sobre o campo científico, enfatizando a luta pelo monopólio da competência científica. A escolha do tema deveu-se ao recente reconhecimento, pela comunidade científica, da eficácia do medicamento conhecido como "óleo de Lorenzo", desenvolvido a partir de pesquisas feitas por Augusto e Michaela Odone, pais de Lorenzo e protagonistas da história. Aqui, foi realizado um estudo observacional, tipo de observação de "segunda mão", indireta e não participante. Na revisão bibliográfica tentou-se contextualizar, de maneira sucinta, o método científico e a origem das abordagens quantitativa e qualitativa, identificando, com base no filme, as relações de poder que permeiam o campo científico. É possível concluir que o discurso de autoridade científica é questionável e que a ruptura do monopólio da competência científica pode contribuir para ampliar o conhecimento, sem que necessariamente sejam alteradas as relações de poder.The purpose of this paper is to present a careful examination of the relations of power shown in the movie "Lorenzo's Oil", using as a basis for argument the work of Pierre Bourdieu (1993) concerning the scientific field, with emphasis on the struggle for the monopoly of scientific competence. The movie analyzed herein is based on a true and ongoing story. The motivation for the choice of this theme strems from the recent acknowledgement, by the scientific community, of the efficacy of the medicine known as "Lorenzo's Oil", developed from research by August and Michaela Odone, Lorenzo's parents and protagonists of the story. The observational study was conducted as a kind of indirect observation with no participation by the researcher. As the paper unfolds, it attempts to place briefly in context the scientific method and the origin of both quantitative and qualitative approaches, identifying, based on the movie, the power relations that are inherent in the scientific field. It is possible to conclude that the speech of scientific authority can be questioned and that the rupture of the monopoly of the scientific ability may help to increase the amount of knowledge without necessarily modifying the relations of power

Remote sensing from unmanned aerial vehicles for 3D urban modelling: case study of Loulé, Portugal

Data acquisition using Unmanned Aerial Vehicles (UAVs) is currently a fast and low-cost Remote Sensing approach. UAVs have become standard platforms for applications in photogrammetric data capture. This capture is still only feasible for small areas, around dozens of hectares. In view of our description, we can say that the data obtained using UAVs are useful for 3D urban modelling, i.e., buildings and urban areas, with a view to support large scale urbanism and urban planning studies. The data were gathered from RGB UAV imagery at a height of 100 meters covering the city centre of Loulé, Portugal. To conduct the UAV survey the following steps were followed from data acquisition through processing 3D urban models: a) establishing flight plan parameters (height, overlapping, time, focal distance, camera data, spatial resolution) and collecting data survey (regarding preparation aspects such as safety, interferences, and calibration); b) loading photos; inspecting loaded images and removing unnecessary images; c) aligning photos; d) building dense point clouds; e) building a mesh; building a 3D polygonal model; f) texturing the 3D model; g) calculating DEM and DTM; h) creating an orthoimage; and i) exporting results. After processing the data, we arrived at two highly accurate 3D urban models. Taking these results into consideration, we have integrated them into urban plans in order to show their usability in the planning process of a city

Comunicação Cientifica - Distribuição Geopolítica da Fasciolose Hepática na Ilha de Santiago, Cabo Verde

O trabalho foi realizado no intuito de registrar a distribuição geopolítica da Fasciolose Hepática na Ilha de Santiago, Cabo Verde. Durante a avaliação, realizada de maio a junho de 2008, foram registrados tamanho e taxas de infecção do molusco, pH e temperatura da água e taxas de infecção de vertebrados. As amostras de moluscos e de fezes de bovinos foram coletadas, de forma aleatória, em todos os municípios da Ilha de Santiago, com exceção de Tarrafal, e, devidamente embaladas, encaminhadas para o Laboratório do Instituto Nacional de Investigação e Desenvolvimento Agrário (INIDA), onde foram analisadas. As análises demonstraram resultados positivos para a coproscopia de bovinos e a presença do hospedeiro intermediário (Lymnaea natalensis) em todos os municípios visitados. Também ficou demonstrada uma correlação positiva entre a taxa de infecção dos hospedeiros vertebrados e invertebrados, sendo que o maior índice foi registrado no Município de Santa Cruz (72,72%) e o menor no da Praia (16,66%). A taxa de infecção média verificada para os moluscos e os bovinos foi de 51,51% e 37,15%, respectivamente.GEOPOLITIC DISTRIBUITION OF HEPATIC FASCIOLOSIS ON SANTIAGO ISLAND, CAPE VERDE. A survey was carried out in order to study the geopolitical distribution of fascioliasis on Santiago Island, Cape Verde. During the evaluation, conducted from May to June 2008, measurements were made and recorded regarding the size and infection rates of the snail, pH and water temperature and vertebrate infection rates. Snails and bovine feces samples were collected at random in all municipalities of Santiago Island, except Tarrafal, properly packed, and sent to the Laboratory of National Institute of Agricultural Research and Development (INIDA) where they were analyzed. The results showed positive results for stool examinations of cattle and the presence of an intermediate host (Lymnaea natalensis) in all localities visited. A positive correlation was also found between the vertebrate and invertebrate infection rate, with the highest rate recorded in Santa Cruz (72.72%) and the lowest in Praia (16.66%). The average infection rate observed for the snails and cattle was 51.51% and 37.15%, respectively

The Force Between Giant Magnons

We compute the force and torque between well-separated, slowly-moving Giant Magnons with arbitrary orientations on S^5. We propose an effective Hamiltonian for Giant Magnons in this regime
