OBJECTIVE To investigate eye injuries resulting from frontal automobile crashes and to determine the effects of frontal air bags. METHODS The National Automotive Sampling System database files from January 1, 1993, through December 31, 1999, were examined in a 3-part study that included an investigation of 22 236 individual crashes that occurred in the United States. A new 4-level eye injury ...

Occupants’ presence and actions within the built environment are crucial aspects related to understanding variations in energy use. Within this chapter, first, a nomenclature for the field of research dealing with occupants in buildings is defined. This nomenclature distinguishes between occupants’ presence and behavior, states and actions, adaptive triggers, non-adaptive triggers, and contextu...

OBJECTIVE This study aimed to investigate the crash characteristics, injury distribution, and injury mechanisms for Maximum Abbreviated Injury Score (MAIS) 2+ injured belted, near-side occupants in airbag-equipped modern vehicles. Furthermore, differences in injury distribution for senior occupants compared to non-senior occupants was investigated, as well as whether the near-side occupant inju...

Energy inefficiency and underlying occupant discomfort associated with building thermal management systems have led to development of human-in-the-loop control system. Minimizing total energy consumption and maximizing comfort of all the occupants present is the major objective of such system based on human comfort feedback. However, the approaches proposed so far lack a built-in mechanism to e...

BACKGROUND In 2001, 6.3 million passengers were involved in motor vehicle crashes. This study aimed to determine the number of work days lost as a result of motor vehicle crashes and factors that influenced people's return to work. METHODS This was a retrospective, population based cohort study of occupants in motor vehicles involved in crashes from the 1993-2001 Crashworthiness Data System p...

This case study investigates the effects of ventilation intervention on measured and perceived indoor air quality (IAQ) in a repaired school where occupants reported IAQ problems. Occupants' symptoms were suspected to be related to the impurities leaked indoors through the building envelope. The study's aim was to determine whether a positive pressure of 5-7 Pa prevents the infiltration of harm...

BACKGROUND Seat belts are designed to reduce injuries due to road crash among vehicle occupants. AIMS This study aims to determine the availability of seat belt in vehicles and compliance with seat belt use among vehicle occupants. MATERIALS AND METHODS This was a 24-h direct observational study of seat belt usage among vehicle occupants in Makurdi, Benue State, Nigeria. By direct surveilla...

Studies of past emergency events have revealed that occupants’ behaviors, local geometry, and environmental constraints affect crowd movement and govern the evacuation. In addition to comply with code and standards, building designers need to take into consideration the occupants’ social characteristics and the unique layout of the buildings to design occupant-centric egress systems. This paper...
