Riscos de acidentes e mortes em usuários de motocicletas em Uberlândia MGBonito, Rosuita Frattari 19 September 2011 (has links)
Objects of desire in the twentieth century, motorcycles are today subject of risk due to
the increase of the fleet followed by the increase of peoples purchasing power and also the
increase of shortcomings public transport. This study aimed to identify the risk of accidents
and fatalities among motorcyclists in Uberlândia, MG, and their own perception of risk,
considering the type of motorcycle used, whether for leisure, work or transport. We used three
instruments to collect data with identification variables, behavior and perception of risk to the
subjects. Of 209 interviewed done in 2005, 132 were followed for 24 months between 2005
and 2007, by telephone, and 86 of them also responded to an interview about his own
perception of risk in 2007. The results show that there are differences in risk between the
three types of motorcycle uses for variables such as age, religion, education, marital status,
use of safety equipment, kilometers run per month, ethnicity, profession, alcohol use, number
of leisure hours per week, personal income and the to engine capacity of the motorcycle CC (
cubic centimeters). In risk perception of the motorcycle driverss, they point to a fragility of
law enforcement, blaming others for risk behaviors in which they get envolved. We conclude
that public policy should consider the traffic is made by and for people, so they should guide
its interventions taking account the plurality of human subjects. / De objetos de desejo, no século vinte, as motocicletas representam hoje um objeto de
risco em decorrência do aumento da frota acompanhando o aumento do poder aquisitivo da
população e também do aumento das deficiências do transporte público. Este estudo teve
como objetivo identificar o risco de acidentes e mortes em motociclistas em Uberlândia, MG,
e sua própria percepção de risco, considerando o tipo de uso da motocicleta, se para lazer,
trabalho ou transporte. Foram utilizados três instrumentos de coleta de dados com variáveis de
identificação, de comportamento e da percepção de risco dos sujeitos. De 209 entrevistados
inicialmente em 2005, 132 foram acompanhados durante 24 meses, entre 2005 e 2007, por
telefone, e 86 deles responderam também a uma entrevista sobre a sua própria percepção de
risco em 2007. Os resultados mostram que há diferenças nos riscos entre os três tipos de usos
da motocicleta, para variáveis como idade, religião, escolaridade, estado civil, uso de
equipamentos de segurança, quilometro rodados por mês, etnia, profissão, uso de álcool,
número de horas de lazer por semana, renda pessoal e cilindradas da motocicleta. Na
percepção dos riscos pelos próprios motociclistas, eles apontam um Estado frágil no que se
refere à aplicação da lei, responsabilizando terceiros pelos comportamentos de risco aos quais
se submetem. Conclui-se que as políticas públicas devem considerar que o trânsito é feito por
e para as pessoas, portanto devem balizar suas intervenções levando em conta a pluralidade
dos sujeitos humanos. / Doutor em Geografia

Analysis and improvement of risk assessment methodology for offshore energy installations : Aspects of environmental impact assessment and as-built subsea cable verificationOlsson, Andreas January 2023 (has links)
In the expansion of offshore sustainable energy systems, there is growing pressure on the environment and permit processes and the accumulation results in much higher total risk for accidents of future assets. Anticipating the problems at the design stage and improving verification is likely to increase energy development and reduce costs. This thesis explores offshore DST (Decision Support Tools) and risk verification of subsea cable assets.For subsea cables, a statistical method is proposed utilizing measurement data together with shipping traffic data (AIS) to estimate the environmental risk and risk of accidents of installed cable assets. This should partially solve issues of improving design using more data and surveys and utilizing mechanical and sensor-specific characteristics to improve the confidence and burial estimation, contrary to today’s methodology. The implication of the two studies of cable burial risk assessment techniques and verification shows how a developed methodology can solve issues for verifying the integrity of an installed asset. Putting our methodology into practice involves many challenges. For the marine Decision Support Tool (DST) and sustainable energy development, to estimate potential savings if permit processes would be shorter and less burdensome without degrading the quality of the EIA (Environmental Impact Assessment). A method is proposed to model various scenarios of effective savings from the development of a DST to reduce costs spent on EIA permitting by the offshore energy developers. The study of the implication of the marine EIA DST shows a quantifiable estimate of the savings potential for permit processes for sustainable offshore development, and results indicate a need for optimization of DST development, which can be an essential factor in its implementation and success.
