OBJECTIVE To investigate comparative road user crash and fatality rates in Japan between 2000 and 2010 in the elderly and young. METHODS Data from the Japan Ministry of Health, Labor and Welfare Vital Statistics Database and the Institute for Traffic Accident Research and Data Analysis were used to calculate crash rates by age group, vehicle, and license category. RESULTS Fatal crash rates ...

Incomplete combustion of fuel in motor vehicles results in the emission of submicron carbonaceous particles which, after cooling and dilution, contain varying quantities of extractable organic constituents. These organics are mutagenic in bacteria. Confirmatory bioassays in mammalian cells provide the capability of detecting chromosomal and DNA damage in addition to gene mutations. In order to ...

Japan’s Intelligent Transport Systems (ITS) project for safe and comfortable transpor­ tation is steadily progressing. To improve safety, information technology (IT) should be applied to most of Japan’s traffic environments. In response, the Fujitsu Group has installed IT equipment into motor vehicles in line with a government policy of using IT to bring transportation systems fully into the 21...

BACKGROUND Concurrent use of marijuana and alcohol in drivers is of increasing concern but its role in crash causation has not been well understood. METHODS Using a case-control design, we assessed the individual and joint effects of marijuana and alcohol use on fatal crash risk. Cases (n = 1944) were drivers fatally injured in motor vehicle crashes in the United States at specific times in 2...

The Food and Drug Administration (FDA or we) is issuing a final rule to establish requirements for shippers, loaders, carriers by motor vehicle and rail vehicle, and receivers engaged in the transportation of food, including food for animals, to use sanitary transportation practices to ensure the safety of the food they transport. This action is part of our larger effort to focus on prevention ...

Background: Road traffic accidents (RTAs) are an emerging public health problem. It is estimated that more than 5 million people between 17-40 years of age die annually as a result of RTAs worldwide. Currently, RTA is the tenth leading cause of disease burden in the developing countries, especially in the Sub-Saharan African countries. The objective of the study was to analyze the proportion of...

Path planning method for unmanned underwater vehicles (UUV) homing and docking in movement disorders environment is proposed in this paper. Firstly, cost function is proposed for path planning. Then, a novel particle swarm optimization (NPSO) is proposed and applied to find the waypoint with minimum value of cost function. Then, a strategy for UUV enters into the mother vessel with a fixed angl...

In the 1950s evidence of an ongoing epidemic of lung cancer in the United States and Western Europe led researchers to examine the role of outdoor air pollution, which was considered by some to be a likely cause. Although epidemiologic research quickly identified the central role of cigarette smoking in this epidemic, and despite progress in reducing outdoor air pollution in Western industriali...

BACKGROUND Although the numbers of total knee arthroplasty (TKA) are increasing, there is only a small number of studies investigating driving safety after TKA. The parameter 'Brake Response Time (BRT)' is one of the most important criteria for driving safety and was therefore chosen for investigation.The present study was conducted to test the hypotheses that patients with right- or left-sided...

OBJECTIVES To describe the frequency, nature and outcome of driveway injuries in children. DESIGN Retrospective case series of driveway-related injuries in children under 16 years of age admitted to the New Children's Hospital (NCH), New South Wales, from November 1995 to February 2000, and deaths reported to the New South Wales Paediatric Trauma Death (NPTD) Registry from January 1988 to Dec...
