Local culture and tourism: the historical heritage of São Vicente - São Paulo
The utilization of historic heritage like tourist attraction is the subject of this paper about São Vicente, coastal city of São Paulo. For decades it remained at the edge of local develop. Public Action orientate towards valorization of facts and historic sites associated with infrastructure change this image and contribute to the conscience of cultural value principally to redeem the local identity and the residents self-esteem lost in that long period of inertia.O aproveitamento da herança histórica como atrativo turístico é o tema deste artigo sobre São Vicente, município situado no litoral do Estado de São Paulo que, durante muitas décadas, permaneceu à margem do processo de desenvolvimento regional. Ações públicas direcionadas para a valorização de fatos e de sítios históricos associadas a obras de infra-estrutura urbana transformaram a imagem, contribuíram para a conscientização dos valores culturais e, principalmente, para resgatar a identidade local e a autoestima dos residentes perdidas no longo período de estagnação
Residências secundárias: as fontes estatísticas e a questão conceitual
Análise teórica de residências secundárias como modalidade de alojamento turístico particular, utilizado temporariamente nos momentos de lazer, por pessoas que têm domicílio permanente num outro lugar. A partir da abordagem do tema na literatura específica, estabelece-se a relação entre as fontes estatísticas e a questão conceitual para chegar à compreensão do termo no Brasil.This is a theoretical analysis of secondary residences as private tourism housing, used temporarily during leisure time by people who live elsewhere. Trough the approach brought by the specific literature, statistical sources are related with conceptual questions to arrive at the comprehension of the tem in Brazil
Documento de interesse para a geografia histórica de São Paulo
The “Planta da Estrada entre as Cidades de São Paulo e de Santos, levantada em 1831 por J.M. de Vasconcelos, e copiada em 1848 por Machado de Oliveira” is one of the several cartographic records existed in the Library of Museu Paulista of University of São Paulo. Having detailed information of great geographical and historical importance this plan becomes a helpful source for the acquaintance with the spatial organization as well as for the study of the apropriation and proporty of the land represented in that area
A dosimetric comparison of 3D-CRT, IMRT and IMAT treatment techniques — assessment from radiation protection point of view
Background: The purpose was to assess the impact of irradiation technique type and beam energy on the mixed radiation field around the medical linear accelerator (linac) in terms of radiation quality and related radiation protection quantities.
Materials and methods: Seven radiotherapeutic plans with Alderson-Rando anthropomorphic phantom [different techniques: conventional three-dimensional conformal radiotherapy (3D-CRT), intensity-modulated radiotherapy (IMRT) and intensity modulated arc therapy (IMAT), different beams: 6 MV or 18 MV, and their arrangements) were prepared for the case of prostate malignancy. Recombination chambers REM-2 and GW2 were positioned on the treatment couch 100 cm from the beam axis at the height of the isocentre. Recombination chambers REM-2 and GW2 were used for recombination index of radiation quality Q4 determination, measurement of total tissue dose Dt and calculation of gamma and neutron components to Dt. Estimation of Dt and Q4 allowed for the ambient dose equivalent H*(10) calculations for each plan.
Results: For plans prepared with 6 MV beams, Q4 values within the limits of uncertainty were equal to one, which confirms the correctness of the measurement method. For plans implemented with 18 MV beams, the value of Q4 was in the range of 3.7–5.7. Comparison between treatment techniques indicates that the lowest exposure resulting from out-of-field doses comes from 6 MV IMAT (0.7 mSv), whereas the highest one is from 18 MV IMRT (55.1 mSv).
Conclusion: With the recombination chambers technique it was confirmed that the choice of beam energy directly affects the generation of photoneutrons. The treatment plan technique can have a significant impact on the out-of-field dose
Turismo e repercussões no espaço geográfico
The practice of tourism comes together to introduce changes in the geographic space by unchaining a great variety of problems, proposals and alternatives that, in a comnon way, shaw up linked to the environment. This analysis unveils echoes of tourism in the geographic space, ranging from broad environmental matters to the peculiar example of rough fishermencommunities that became into outskirts nuclei.A prática do turismo concorre para introduzir mudanças no espaço geográfico desencadeando uma grande variedade de problemas, propostas e alternativas que, de um modo geral, aparecem vinculadas ao meio-ambiente. Esta análise revela repercussões do turismo no espaço geográfico, incluindo desde questões ambientais amplas, até o exemplo particularizado de comunidades de pescadores artesanais que se transformaram em núcleos de periferia urbana

The article is an attempt to answer questions connected with objects, collecting and owning them, and their function. What is an object in a person’s life, how many emotions and meanings does it carry? Is it beautiful or useful and is beauty utility? Why does it define the times it was created in, and why, in the course of time, acquiring meaning, does it become timeless and everlasting? How does a collector make his way in the world of objects, what is his attitude to them? Where is the borderline between the desire to possess and the madness of possessing at all costs? Can the line be drawn? Museum exhibitions and their evaluation; exhibition correctness and viewers’ emotions
