A seamless location measuring system with WiFi beacon utilized and GPS receiver based systems in both of indoor and outdoor location measurements is proposed. Through the experiments in both of indoor and outdoor, it is found that location measurement accuracy is around 2-3 meters for the locations which are designated in both of indoor and outdoor. Keywords—GPS receiver; WiFi beacon; seamless ...

Word Count: 191 Word Count: 3367 Pages: 16 Tables: 4 Abstract BACKGROUND: Recent research has shown that neighborhood characteristics are associated with obesity prevalence. While food advertising in periodicals and television has been linked to overweight and obesity, it is unknown whether outdoor advertising is related to obesity. METHODS: To test the association between outdoor food advertis...

This article examines the characteristic of affordances of different outdoor environments, related to the influences of children's physical activity levels. Qualitative observation studies in a Norwegian kindergarten were conducted of 3- to 5-year-olds into the natural environment and in the kindergarten's outdoor area. An ecological approach was important from both an analytical and theoretica...

The purpose of this study was to investigate the effects of non-steady locomotor activities on load predictability in two goat forelimb bones and to explore the degree to which bone curvature influences load predictability. We measured in vivo bone strains in the radius and metacarpus of juvenile goats performing a variety of natural behaviors in an outdoor arena and compared these strain magni...

Geographic information systems traditionally dealt with only outdoor spaces. In recent years, indoor spatial information systems have started to attract attention partly due to the increasing use of receptor devices (e.g., RFID readers or wireless sensor networks) in both outdoor and indoor spaces. Applications that employ these devices are expected to span uniformly and supply seamless functio...

The development of self-efficacy from participation in adventure education is consistently viewed as a positive and desirable outcome. However, outdoor leadership training is a context in which self-efficacy enhancement should be approached with caution. Recent research outside the field of outdoor leadership and adventure education has called into question the assumption of a consistently posi...

This study was carried out to determine the concentration of lead (Pb), anions, and cations at six primary schools located around Kuala Lumpur. Low volume sampler (MiniVol PM10) was used to collect the suspended particulates in indoor and outdoor air. Results showed that the concentration of Pb in indoor air was in the range of 5.18 ± 1.08 μg/g-7.01 ± 0.08 μg/g. All the concentrations of Pb in ...

Hip fractures in older persons are associated with both low levels of daily physical activity and loss of outdoor mobility. The aim was to investigate if accelerometer-based measures of physical behaviour can be used to determine if people undertake outdoor walking and to provide reference values for physical behaviour outcomes related to outdoor mobility. Older persons (n = 245), ≥70 years, on...

OBJECTIVES Although risk factors for indoor falls among older individuals have been well studied, little is known about the etiology of outdoor falls. We examined risk factors for outdoor falls among middle-aged and older adults. METHODS We analyzed data on the most recent fall during the past year among participants aged 45 years and older in the control group (N=2193) of a case-control stud...

Research indicates that promoting time spent in the outdoors and outdoor physical activity increases children's daily physical activity and improves health. One method showing promise is doctor prescriptions for outdoor physical activity for children; however, no empirical evidence currently exists on prescriptions for children's outdoor physical activity. A pilot study was conducted at one ped...
