Acordos de pesca: a efetividade dos acordos para o desenvolvimento local nas comunidades do Pixuna e Jarí do Socorro no município de Santarém-PA

A presente pesquisa propôs-se investigar a efetividade dos acordos de pesca na Amazônia enquanto instrumento de gestão participativa através das populações residentes nas comunidades do Pixuna e Jarí do Socorro no município de Santarém-Pa. Para tanto, analisou-se como as referidas comunidades veem os acordos de pesca vigente, já que as mesmas são consideradas agroextrativistas e que possui na atividade pesqueira sua fonte de renda, proteína e ao longo dos anos vem praticando o mecanismo do acordo de pesca como forma de gestão desta atividade. Também buscou-se entrevistar representantes de ONGs como o IPAM enquanto organização responsável em divulgar de uma maneira mais simples para os pescadores o que vem a ser na forma da Lei e na prática a Instrução Normativa do IBAMA Nº 29/2002 que trata da criação dos acordos de pesca; a Colônia de Pescadores Z-20 representante legal e responsável em defender os interesses e direitos dos trabalhadores do setor artesanal da pesca local perante os órgãos públicos e a sociedade e o IBAMA representante oficial do poder publico, gestor e fiscalizador de quaisquer ações de pesca predatória e de degradação do meio ambiente evidenciados nos acordos implantados nas comunidades. A pesquisa descreve o ambiente de várzea como cenário para essas relações que se estabelecem a partir do uso de um recurso de acesso livre a todos como é o caso do pescado. No que diz respeito à metodologia as técnicas utilizadas se constituíram em: observação direta, aplicação de entrevistas semi-estruturadas e questionários. Foram apresentadas as características da pesquisa, os seus sujeitos e as informações relativas à coleta e à análise dos dados. Assim, o estudo caracterizou-se como qualitativo. Os dados foram analisados através de procedimentos estatísticos básicos com a utilização do software SPSS a partir de frequências e estimativas de parâmetros descritivos, com representação de tendências através de tabelas e gráficos, que tem como finalidade uma melhor visualização destas análises e observações para o contexto da pesquisa. Por fim, foram feitas as considerações finais do estudo, onde foi identificado que a falta de articulação entre os comunitários residentes nas localidades, e das comunidades com o poder publico podem, ser apontados como importantes fatores na decadência observada nos acordos de pesca vigente; outro ponto interessante e de importância considerável é a ausência do órgão responsável pela fiscalização das regras encontradas nos acordos de pesca, o IBAMA. Diante disso, foram sugeridas algumas recomendações aos membros das organizações analisadas.

Um método para reconstrução de superfícies baseado em nuvem de pontos visando representações em multirresolução

The representation of real objects in virtual environments has applications in many areas, such as cartography, mixed reality and reverse engineering. The generation of these objects can be performed in two ways: manually, with CAD (Computer Aided Design) tools, or automatically, by means of surface reconstruction techniques. The simpler the 3D model, the easier it is to process and store it. Multiresolution reconstruction methods can generate polygonal meshes in different levels of detail and, to improve the response time of a computer program, distant objects can be represented with few details, while more detailed models are used in closer objects. This work presents a new approach to multiresolution surface reconstruction, particularly interesting to noisy and low definition data, for example, point clouds captured with Kinect sensor

O efeito da autocorrelação no desempenho dos gráficos de X e R e dos gráficos de X e S²

Control charts are very important tools in statistical quality control of industrial processes and its use started last century. Since its development, the charts have always been attributed to independent processes, i.e. without any correlation between samples. But nowadays, with the high level of automation in the industrial environment, it is noticeable the autocorrelation factor between samples. The main Xcharts used in monitoring quality characteristics represented by continuous variables are the mean (X ), amplitude (R) and variance (S²). Therefore, this work aims to analyze the performance of X and R charts and in of X and S² charts with different sample sizes (4 and 5) for monitoring autocorrelated processes. Through computer simulations using the Fortran software and the use of mathematical expressions was possible to obtain data and performance analysis of the detection power charts for independent observations and for autocorrelated observations according to the model AR (1). The results show that the effect of autocorrelation reduces the ability of monitoring the control charts and that, the greater this effect, the slower the chart becomes in misfits signaling

Influence of crown-to-implant ratio, retention system, restorative material, and occlusal loading on stress concentrations in single short implants

Purpose: The aim of this study was to assess the contributions of some prosthetic parameters such as crown-to-implant (C/I) ratio, retention system, restorative material, and occlusal loading on stress concentrations within a single posterior crown supported by a short implant. Materials and Methods: Computer-aided design software was used to create 32 finite element models of an atrophic posterior partially edentulous mandible with a single external-hexagon implant (5 mm wide × 7 mm long) in the first molar region. Finite element analysis software with a convergence analysis of 5% to mesh refinement was used to evaluate the effects of C/I ratio (1:1; 1.5:1; 2:1, or 2.5:1), prosthetic retention system (cemented or screwed), and restorative material (metal-ceramic or all ceramic). The crowns were loaded with simulated normal or traumatic occlusal forces. The maximum principal stress (σmax) for cortical and cancellous bone and von Mises stress (σvM) for the implant and abutment screw were computed and analyzed. The percent contribution of each variable to the stress concentration was calculated from the sum of squares analysis. Results: Traumatic occlusion and a high C/I ratio increased stress concentrations. The C/I ratio was responsible for 11.45% of the total stress in the cortical bone, whereas occlusal loading contributed 70.92% to the total stress in the implant. The retention system contributed 0.91% of the total stress in the cortical bone. The restorative material was responsible for only 0.09% of the total stress in the cancellous bone. Conclusion: Occlusal loading was the most important stress concentration factor in the finite element model of a single posterior crown supported by a short implant.

Qualitative methodogy: revealing a new path for research in dentistry

Currently, it is easy to find health professionals who not only attach importance to qualitative methods, but also recognize their help to better understand their patients' lives. However, its use in dentistry is still incipient, either due to ignorance or because of technical / operational difficulties in identifying possibilities for their use in research. Thus, the purpose of this study was to review the literature on the characteristics and peculiarities of the qualitative methodology, demonstrating their techniques of collecting, recording and analyzing data. For this, we performed a descriptive literature, from a survey in the "LILACS", "BBO" and "PUBMED" databases, by keywords related to the theme, selecting only the papers that mentioned the "importance" of qualitative research, the "characteristics and fundamentals," and the "techniques of collecting, recording and data analysis" involving this methodology. It was found that all studies have highlighted the importance of qualitative research to the construction of new knowledge that cannot be achieved by quantitative data. We found many different techniques to gather, record and analyze qualitative data applied to the dentistry field. It was concluded that qualitative research represents a new path to be followed by dentistry, so that we are able to plan actions in ethical and humane public health dentistry, bringing better results to the population, because of the depth of knowledge that your date can.
