INTRODUCTION Seat belt use reduces the risk of injuries and fatalities among motor vehicle occupants in a crash, but belt use in rear seating positions is consistently lower than front seating positions. Knowledge is limited concerning factors associated with seat belt use among adult rear seat passengers. METHODS Data from the 2012 ConsumerStyles survey were used to calculate weighted percen...

Proper seat belt use saves lives; however, the use rate decreased in Korea. This study aimed to measure the magnitude of the preventive effect of seat belt on case-fatality across drivers and passengers. We used the Emergency Department based Injury In-depth Surveillance (EDIIS) database from 17 EDs between 2011 and 2012. All of adult injured patients from road traffic injuries (RTI) in-vehicle...

The hot gases produced by the internal combustion engines passes through the exhaust valve and causes high temperatures in the exhaust valve and its seat. To avoid damaging the exhaust valve, heat must be transferred from the valve to its seat during the contact they make at the opening and closing cycle. Heat transfer rate from the exhaust valve to its seat is a function of many factors. One o...

OBJECTIVE To digitally model (three-dimensional, 3D) the course of the pudendal arteries relative to the bony pelvis in the adult male, and to identify sites of compression with different bicycle riding positions as a potential cause of penile hypoxia and erectile dysfunction. SUBJECTS AND METHODS 3D models were made from computed tomography scans of one adult male pelvis (a healthy volunteer...

The severity of injuries sustained by 2577 car occupants in road traffic accidents in the catchment area of one district accident service during February 1982 to January 1984 inclusive was assessed using the injury severity score system. In the first 12 months the mean injury severity score for front seat occupants injured in a road traffic accident was 4.94 and in the second 12 month period, a...

OBJECTIVE Many modern cars have seat belt reminders (SBRs) using loud and clear sound and light signals. These systems have developed over the last few years. This study investigates how these modern systems influence the seat belt use in real-life traffic in built-up areas in some European cities. METHODS The data were collected by field observations in major cities in six European countries...

during centuries, humans have changed their environment into a perspective of cultural heritage using tact and wisdom. these perspectives that show the legacy of human civilization, have established a long cultural relationship via safety international pathways. hence, investing for maintenance of critical infrastructures which is the safe way, seems to be necessary. the main problem is not the...

OBJECTIVES To monitor preterm infants in a cot and a car seat and compare an observed car seat trial with polysomnography (PSG). DESIGN Non-randomised controlled trial. SETTING Regional neonatal unit. PATIENTS Preterm infants before discharge. INTERVENTIONS Nap PSG respiratory and sleep variables were measured including gastro-oesophageal pH. Nurse observations included respiratory dist...

Roadway incidents involving motorized vehicles accounted for 24% of fatal occupational injuries in the United States during 2013 and were the leading cause of fatal injuries among workers.* In 2013, workers' compensation costs for serious, nonfatal injuries among work-related roadway incidents involving motorized land vehicles were estimated at $2.96 billion.(†) Seat belt use is a proven method...

BACKGROUND Driving has been associated with signs and symptoms caused by vibrations. Sitting causes the pelvis to rotate backwards and the lumbar lordosis to reduce. Lumbar support and armrests reduce disc pressure and electromyographically recorded values. However, the ideal driver's seat and an optimal seated spinal model have not been described. OBJECTIVE To determine an optimal automobile...
