Limites da engenharia de transporte e a estrada minada: o caso da BR 316, Km 0 ao Km 10

A Organizaçãao Mundial da Sáude caracteriza o trânsito como um problema de sáude pública, motivo pelo qual se justificam as preocupações e os esforços de diversos países em criar políticas que venham a frear os índices cada vez mais crescentes de acidentes de trânsito que trazem prejuízos sociais e financeiros a todos. Neste sentido, a conservação da infraestrutura das rodovias ganha um papel relevante nas discussões que tratam os acidentes e suas causas, vez que a infraestrutura de uma rodovia pode ser apontada como um fator determinante para tais ocorrências. Diante disto, esta dissertação tem como objetivo investigar de que forma a precariedade estrutural da Rodovia Federal BR 316, entre os quilômetros 0 ao 10, potencializou a ocorrência de acidentes de trânsito nos anos de 2009 a 2012. Para tanto, lançou-se mão de uma metodologia baseada em explorações teóricas aliadas a análise de informações provenientes do banco de dados da Polícia Rodoviária Federal e pesquisa de campo, materializada a partir da apresentação de fotos ilustrativas do trecho pesquisado, possibilitando o desenvolvimento de um novo Índice de Qualidade para a Rodovia. Os dados colhidos foram tratados a partir da aplicação das técnicas estatísticas análise descritiva e análise multivariada a fim de confirmar a hipótese suscitada. Destaque-se que, no trecho pesquisado o fluxo de veículos e pedestres é intenso e, além, é um intervalo quilométrico que apresenta diversos problemas estruturais como, por exemplo, o aumento e a diminuição do número de pistas de rolamento, a má qualidade dos retornos, a falta de segurança e higiene das passarelas, a descontinuidade dos acostamentos, a inadequação das paradas de ônibus, enfim. No que tange à acidentes e às suas causas, pôde-se constatar que no ano de 2010 houveram mais ocorrências, especialmente, do tipo colisão com bicicleta, colisão com objeto móvel, colisão frontal e colisão transversal, motivadas por desobediência à sinalização, velocidade incompatível, ingestão de álcool, dentre outros. Finalmente, deve-se ressaltar o fato de que nos trechos considerados ruins, além da falta de atenção, a principal causa de acidentes é o defeito na via, corroborando-se então, a hipótese que a precariedade da infraestrutura da rodovia potencializou as ocorrências de acidentes de trânsito, no período de 2009 a 2012. Diante disto, é possível afirmar que o acidente de trânsito é um fato social, consubstanciando como um problema que abarca aspectos sociopolíticos e culturais da sociedade moderna, mas que também é potencializado pelo estado de conservação estrutural das Rodovias.

Differential organotin sensitivity in two Leucozonia species from a ship traffic area in southeastern Brazil

Tributyltin exposure is the primary cause of imposex development in gastropods, making them excellent bioindicators. The present research represents the first examination of butyltin (BT) contamination in surface sediments associated with imposex in Leucozonia nassa and L. ocellata in a harbour complex area in Espirito Santo, southeastern Brazil. The objectives of this study were to evaluate the organotin pollution in the area and to assess the sensitivity of both species to BT pollution through imposex development. Specimens were collected between 2007 and 2010 and the sediments were sampled in 2007. Imposex intensity was evaluated based on the percentage of imposexed females, the relative penis length index (RPLI) and the average value of the vas deferens sequence index (VDSI). BTs were analysed using gas chromatography equipped with a pulsed flame photometric detector (PFPD). The results demonstrated the occurrence of elevated concentrations of BTs in the sediment ranging from 383.7 to 7172.9 ng Sn g(-1), indicating a severe contamination of the area, which was confirmed by the biological monitoring results. Our findings also indicated that L. ocellata is a less sensitive species than L. nassa and that this differential sensitivity plays a key role in the distributions of the populations of both species in the studied area.

Implant-retained finger prosthesis with modified retention system

Background: Amputations affect both the physical and the psychological aspects of an individual, causing significant impact on self-esteem. The main causes of finger amputations are work-related accidents with dangerous machinery, road traffic accidents, and animal bites, as well as systemic diseases such as diabetes. This report aims to describe a simple technique for fabrication of implant-retained finger prosthesis with a modified base of the retention system.Case Description and Methods: The O-Ring retention system was used with a modified hexagon-shaped base and a metallic capsule adapted to the acrylic resin to attach the prosthesis to the implant.Findings and Outcomes: The prosthesis was made with silicone, and after osseointegration, it was installed without complications, leading to a patient satisfied with the end result and encouraged to return to social life.

High incidence of preventable deaths during childhood in Porto Velho, Rondonia - Brazil

Background: We aimed to estimate and analyze epidemiological profile of deaths during childhood. Method: We used the databases of deaths provided by Information System of mortality between 2006 and 2010. We selected only those records where the occurrence of deaths corresponded to Porto Velho city and those who were aged between 12 and 48 months old at the moment of death. We examined only deaths from preventable causes and poorly defined. Results: The total number of deaths was estimated to be 103, 48.6% male. High frequencies of deaths occurred (39.8%) in children before reaching two years old. Vast majority of deaths (66.9%) was due to preventable causes, 18.4% by poorly defined causes and nearly one in three by external causes. Approximately one in four were due to traffic accidents, 41.9% by drowning and submersion. Also, there were significant frequencies of deaths associated with respiratory diseases (17.5%) and infectious and parasitic diseases (16.6%). Conclusion: These findings reinforce the importance of studies of infant mortality, drawing attention to the debate on policy design to reduce childhood deaths, especially in acting on preventable causes.

O processo de ensino aprendizagem da educação no trânsito por meio da construção de um personagem heróico

This research project aims to study the relationship between the myths and the automobile, the contributions to the literature of fairy tales and the possible contributions of the heroes of fairy tales can bring to the process of teaching and learning defensive behavior in traffic. Traffic is a phenomenon so common to modern societies that often do not pay attention to their relevance as synonymous with social space and contains diversity of people and behaviors. To counter the image of fatalistic accidents and transgressions, will support us in the virtues of the hero figure to culminate in a collective tale in which children want to rethink their behavior, becoming citizens, with a more preventative and better quality of life. The research will be held in four rooms of elementary school in a city public school that serves children from families of the urban popular classes. The research will seek to analyze how the design of transit for the children and what the increase attributed to the theme, after the establishment of a collective story

Análise dos acidentes automobilísticos atendidos no Hospital das Clínicas no ano de 2010, Botucatu

As a result of the 20th-century industrial development, and particularly after World War II, cars have become an important consumer good, and this has led to a large number of circulating vehicles. To this day, the number of cars has increased exponentially worldwide, which results in a high number of traffic accidents (TAs) every day. TAs are responsible for 1.2 million deaths worldwide each year, and in Brazil, they are considered to be a public health problem, considering that its traffic is regarded as one of the worst and most dangerous in the world. In addition to temporary or permanent physical disabilities that bring great harm to individuals, accidents also cause psychological disorders, such as the post-traumatic stress disorder. Hence, considering the importance of TAs in the country and their outcomes, this study aimed at investigating the epidemiological aspects of car accidents occurring in 2010 who were assisted in the emergency room of a university hospital in São Paulo state. By means of records made by the nursing team and medical records analysis, it was possible to extract a stratified sample of 88 cases involving adults and eight cases involving children. The sample was analyzed by the SAS software for Windows, version 9.2. As regards the accidents involving adults, there was a predominance of males (67%), with an approximate 2:1 ratio in relation to females. The victims’ most frequent age range was 20-29 years (39%), and they were mostly single (56%). The month showing the largest number of occurrences was July, with 17%, and the weekday was Sunday, with 25%. Showing 32%, the time period when most accidents occurred was from 06:00 o’clock p.m. to 11:59 p.m. As regards vehicles types involved, motorcycles were in first place, with 47% of cases, and the most common accident type was crashing between vehicles, with 43%...

Relações entre os acidentes de trânsito e a precipitação na área urbana de Rio Claro (SP)

Traffic accidents are considered a concern for both public agencies and for researchers that are seeking alternatives to reduce the number of deaths and incidents. Thus, the aim of this work was to compile a database of traffic accidents recorded for the 2° Sub-Grouping of the Fire Department of the city of Rio Claro (SP) during the years 2008 to 2010 and related to rain. The result allowed profiling of traffic accidents, recognize critical areas and correlate the rain as an interference factor in the occurrence of traffic accidents in Rio Claro (SP)

Análise da influência da iluminação de rodovias federais com a redução do número de acidentes

The increasing rate of traffic accidents, followed by the high rate of mortality due to these occurrences, favored to the classification of traffic accidents as a public health problem in Brazil. These accidents consume a significant portion of Gross Domestic Product (GDP), especially related to the victims. Considering this scenery with many tragedies and resources being spent only in the end, this paper seeks to examine the influence of federal highways lighting by reducing the number of accidents. Federal Highways sections that received lighting were taken up for study, therefore a survey of statistical data has been raised considering the accidents before and after the route had been illuminated. Taking advantage of the results obtained, an economic analysis has been made considering the amounts consumed by traffic accidents versus the values required for the installation of lighting on highways

This work shows the importance of taking a good organization of space for the improvement of urban public transport. The model of urban transport is used improperly aggravating factor that generates diseconomies to society. The reduction of the use of public transport, degradation of environmental conditions, chronic congestion, poor accessibility and high rates of traffic accidents are common in many cities. The case study will be done in Jundiaí - SP, where actions were taken to try to reverse this situation of crisis in urban transport, as the change in transport network system. Will analyze the proposals adopted for the implementation of the new network model, steps taken, questionnaires and results from these studies. Verifying the effectiveness of the new transport network model adopted and its reflection with users, those who use the transportation and / or who directly suffer the influences this

Optimizing urban traffic flow using genetic algorithm with petri net analysis as fitness function

This paper describes a new methodology adopted for urban traffic stream optimization. By using Petri net analysis as fitness function of a Genetic Algorithm, an entire urban road network is controlled in real time. With the advent of new technologies that have been published, particularly focusing on communications among vehicles and roads infrastructures, we consider that vehicles can provide their positions and their destinations to a central server so that it is able to calculate the best route for one of them. Our tests concentrate on comparisons between the proposed approach and other algorithms that are currently used for the same purpose, being possible to conclude that our algorithm optimizes traffic in a relevant manner.
