Nine species of Anopheles mosquitoes were collected biting humans indoors and outdoors in a malaria endemic village in northern Peninsular Malaysia. Outdoor biting was higher than that observed indoors. Biting of An. maculatus was observed throughout the night. Peak indoor biting occurred at 2130 h while outdoor biting was higher after midnight. Outdoor biting of Anopheles barbirostris and An. ...
We describe an experimental mobile augmented reality system (MARS) testbed that employs di!erent user interfaces to allow outdoor and indoor users to access and manage information that is spatially registered with the real world. Outdoor users can experience spatialized multimedia presentations that are presented on a head-tracked, see-through, head-worn display used in conjunction with a hand-...
This paper proposes a new propagation model to accurately predict outdoor-to-indoor propagation loss. Account is taken of the structural openings along the paths; it is assumed that outdoor-to-indoor paths are possible only through wall openings such as doors and windows. Introducing the angle dependency of the losses with the paths that penetrate the indoor area makes it possible to accurately...
Risky outdoor play has been associated with promoting children's health and development, but also with injury and death. Risky outdoor play has diminished over time, concurrent with increasing concerns regarding child safety and emphasis on injury prevention. We sought to conduct a systematic review to examine the relationship between risky outdoor play and health in children, in order to infor...
An intercept survey using quota sampling design investigated awareness of eight outdoor advertisements among 332 Hong Kong pedestrians aged 15 and above. Awareness of outdoor posters ranged from 19 percent to 50 percent, with an average of 35 percent. Advertising awareness did not differ by sex, age, or educational level. The message response involvement theory was adopted as the theoretical fr...
Indoor nitrogen dioxide (NO₂) concentration is an important factor for personal exposure despite the wide distribution of its sources. Exposure to NO₂ may produce adverse health effects. The aims of this study were to characterize the indoor air quality of wayside shops using multiple NO₂ measurements, and to estimate the contribution of outdoor NO₂ sources such as vehicle emission to indoor ai...
Background: Despite recent UK Governmental policy changes concerning the amount of outdoor, physical activity children are currently engaged in (LTS, 2010), there is a gap in the academic literature concerning children’s personal preferences for structured play and learning through physical activity in outdoor environments. Aim and objectives: This research explores the context of residential o...
