O sistema estuarino Amazônico é influenciado pelo regime de maré e pelas variações da descarga fluvial que modificam o regime das correntes e contribuem com aportes de material particulado em suspensão (MPS) acarretando diversas modificações morfológicas ao longo do rio. A quantificação desses parâmetros fornece um entendimento sobre as taxas de exportação e importação de materiais ou volume e suas implicações na geomorfologia estuarina. O objetivo desse estudo é avaliar a hidrodinâmica, o transporte de volume e de MPS em diferentes períodos nos rios Jacaré Grande, Pará e foz do Tocantins. Coletaram-se dados de velocidade e direção da corrente, maré, turbidez, transporte de volume e MPS, ao longo de um ciclo de maré no período seco (2012) e chuvoso (2013). O rio Pará exportou volume, nos dois períodos. O rio Tocantins importou no período seco e exportou no período chuvoso. O rio Jacaré Grande influenciado pelo rio Amazonas, importou no período chuvoso e exportou no período seco. A análise dos métodos de transporte de volume mostrou uma tendência de exportação em direção ao rio Amazonas e a baía do Marajó no período seco e para baía do Marajó no período chuvoso. Os valores de MPS no período chuvoso foram maiores, sendo decrescente do rio Jacaré Grande até o rio Tocantins, respectivamente período seco e chuvoso. A turbidez seguiu a mesma tendência de MPS com a maré, tendo os valores máximos durante a enchente. Os métodos de transporte de MPS, mostrou valores similares e que obedecia a mesma direção. O rio Jacaré Grande atuou como exportador no período seco e importador no período chuvoso, o rio Pará como exportador nos dois períodos e o rio Tocantins como importador no período seco e exportador no período chuvoso. O sistema formado pelos três rios mostrou a mesma tendência de exportação nos dois períodos, tendo no período seco duas rotas de exportação, o rio Amazonas e a baía do Marajó, e no período chuvoso uma rota de exportação, a baía do Marajó. Anualmente o sistema exporta entre 5 a 7,2 milhões de toneladas, sendo que possivelmente a baía do Marajó recebe entre 3,7 a 5,8 milhões de toneladas, podendo o volume transportado para a região oceânica ser bem maior.Os fluxos de MPS associado à variabilidade das condicionantes ambientais modelam a região estuarina, como na foz do rio Tocantins e na Baía do Guajará, sendo preciso um monitoramento continuo devido a possíveis acidentes náuticos ou a derramamentos de óleo ou qualquer contaminante na região que acarrete danos ao meio.

This analysis estimates several economic benefits derived from national implementation of the National Oceanic and Atmospheric Administration’s Physical Oceanographic Real-Time System (PORTS®) at the 175 largest ports in the United States. Significant benefits were observed owing to: (1) lower commercial marine accident rates and resultant reductions in morbidity, mortality and property damage; (2) reduced pollution remediation costs; and, (3) increased productivity associated with operation of more fully loaded commercial vessels. Evidence also suggested additional benefits from heightened commercial and recreational fish catch and diminished recreational boating accidents. Annual gross benefits from 58 current PORTS® locations exceeded $217 million with an addition $83 million possible if installed at the largest remaining 117 ports in the United States. Over the ten-year economic life of PORTS® instruments, the present value for installation at all 175 ports could approach $2.5 billion.

The purpose of this study was to examine factors which affect driving behaviour and accident rates in women in Australia. Two groups of women (aged 18-23 and 45-50 years) participating in the Australian Longitudinal Study on Women's Health, completed a mailed questionnaire on driver behaviour and road accidents. Self reported accident rates in the last 3 years were 1.87 per 100 000 km for the young drivers (n = 1199) and 0.59 per 100 000 km for the mid-age drivers (n = 1564); most accidents involved damage only, not injury. Mean scores for lapses obtained using the Driver Behaviour Questionnaire, were similar in the two age groups and similar to those found in other studies. In contrast, scores for errors and violations for the young women were higher than for the mid-age group and previous reports using the same instruments. Riskier driving behaviour among young women was associated with stress and habitual alcohol consumption. In the mid-age group, poorer driver behaviour scores were related to higher levels of education, feeling rushed, higher habitual alcohol consumption and lower life satisfaction scores. Accident rates in both groups were significantly related to lapses. Women born in non-English speaking countries had significantly higher risk of accidents compared to Australian-born women: relative risk = 3.40, 95% confidence interval (1.93, 5.98) for the young drivers; relative risk = 1.77, 95% confidence interval (1.11, 2.83) for mid-age drivers. These findings support the need for road safety campaigns targeted at young women to reduce dangerous driving practices, such as speeding,'tail gating' and overtaking on the inside. There is also a need for further research to understand how lifestyle characteristics are associated with higher risk of accidents and to explore factors which might account for the higher risk for women drivers who were born overseas.

Aims: The aims of the present study were to characterize fatal traffic accident victims in a major urban center in Brazil and their association with alcohol consumption. Methods: Cross-sectional study of 907 fatal traffic accident victims in Sao Paulo, in 2005. Results: Adult males between the ages of 25 and 54 represented the majority of cases with positive blood alcohol concentrations (BAC). Overall, males had a higher proportional BAC and mean BAC than females. Pedestrians, particularly those with no detectable BAC, were typically older than other victims. Most accidents (total and BAC-positive) happened on weekends between midnight and 6 a.m. Considering all victims, 39.4% were positive (BAC over 0.1 g/l). When only drivers (automobile, motorcycle and bicycle) were evaluated. 42.3% had BAC over the legal limit (0.6 g/l). Conclusions: Alcohol is associated with nearly half of all traffic accident deaths in the city of Sao Paulo. especially for days and times associated with parties and bars (weekends between 12 a.m. and 6 a.m.).

Background: Traffic accidents constitute the main cause of death in the first decades of life. Traumatic brain injury is the event most responsible for the severity of these accidents. The SBN started an educational program for the prevention of traffic accidents, adapted from the American model ""Think First"" to the Brazilian environment, since 1995, with special effort devoted to the prevention of TBI by using seat belts and motorcycle helmets. The objective of the present study was to set up a traffic accident prevention program based on the adapted Think First and to evaluate its impact by comparing epidemiological variables before and after the beginning of the program. Methods: The program was executed in Maringa city, from September 2004 to August 2005, with educational actions targeting the entire population, especially teenagers and young adults. The program was implemented by building a network of information facilitators and multipliers inside the organized civil society, with widespread population dissemination. To measure the impact of the program, a specific software was developed for the storage and processing of the epidemiological variables. Results: The results showed a reduction of trauma severity due to traffic accidents after the execution of the program, mainly TBI. Conclusions: The adapted Think First was systematically implemented and its impact measured for the first time in Brazil, revealing the usefulness of the program for reducing trauma and TBI severity in traffic accidents through public education and representing a standardized model of implementation in a developing country.

In recent years, alcohol consumption has been considered an important public health problem. Ethanol, the alcohol used in beverages, is a drug that affects the central nervous system (CNS) and impairs driving skills and co-ordination, increasing risk of deaths and injuries derived from crashes and road accidents. Consumption of alcoholic beverages is implicated with premature deaths, injuries and damages caused by motor vehicle crashes, which result in high costs to government and society. Considering that alcohol consumption is the main responsible factor for deaths and disabilities in young people, the aim of this work was to evaluate the prevalence of blood alcohol in offenders and/or fatal and non-fatal victims of traffic occurrences in the region of Ribeirao Preto, Sao Paulo State, from 2005 to 2007. The results revealed that in 2134 cases investigated, blood alcohol positivity was generally found in young adults, 25-45 years old and male. The study showed the high risk of drinking and driving and the importance in establishing actions of prevention and intervention to promote the reduction in the number of traffic occurrences related to consumption of alcoholic beverages.

OBJECTIVES: To estimate the prevalence of occupational injuries and identify their risk factors among students in two municipalities. METHODS: A cross-sectional survey was conducted in public schools of the municipalities of Santo Antonio do Pinhal and Monteiro Lobato, Brazil. A stratified probabilistic sample was drawn from public middle and high schools of the study municipalities. A total of 781 students aged 11 to 19 years participated in the study. Students attending middle and high school answered a comprehensive questionnaire on living and working conditions, as well as aspects of work injuries, and health conditions. Multiple logistic regression models were fitted to estimate risk factors of previous and present occupational injuries. RESULTS: Of 781 students, 604 previously had or currently have jobs and 47% reported previous injuries. Among current workers (n=555), 38% reported injuries on their current job. Risk factors for work injuries with statistically significant odds ratio >2.0 included attending evening school, working as a housekeeper, waiter or brickmaker, and with potentially dangerous machines. CONCLUSIONS: The study results reinforce the need of restricting adolescent work and support communities to implement social promotion programs.

This paper presents a spatial econometrics analysis for the number of road accidents with victims in the smallest administrative divisions of Lisbon, considering as a baseline a log-Poisson model for environmental factors. Spatial correlation on data is investigated for data alone and for the residuals of the baseline model without and with spatial-autocorrelated and spatial-lagged terms. In all the cases no spatial autocorrelation was detected.
