Hiking is a demanding form of exercise that may cause delayed responses of the postural muscles and a loss of somatosensory information, particularly when repeatedly performed for several days. These effects may negatively influence the postural control of hikers. Therefore, the aim of this study was to investigate the effects of a four-day hike on postural control. Twenty-six adults of both se...

Recreational use of nature areas is increasing worldwide. All trail-based activities have a certain degradation effect on vegetation and soil, conflicts between conservation values recreation may occur. Controversy still exists regarding the relative impact mountain bikers compared to hikers trails. In this study, we manipulated intensity from existing, natural-surfaced trails, investigated eff...

Infrared (IR) thermal imaging can detect the warm temperature of human body regardless light conditions, thus small drones equipped with IR camera be utilized to recognize activity for smart surveillance, road safety, and search rescue missions. However, unpredictable motion drone poses more challenges than a fixed camera. This paper addresses detection tracking people through video captured by...

Introduction With the development of Information and Communications Technology (ICT), new forms of geospatial data are emerging in recent years. Among the new and emerging forms of geospatial data, volunteered geographic information (or crowdsourced geographic information) and geosocial networking data are gaining much interest [1–4]. Sources of volunteered geographic information (VGI) include ...

Important issues about climate change are summarized and discussed: A large body of evidence shows that the world climate is getting warmer. Climate models give a consistent explanation of this observation once human-made emissions of greenhouse gases are taken into account. Furthermore, the main source of greenhouse gases comes from the burning of oil, gas and coal, mainly in the industrialize...

Many hiking trails traverse the forests and public lands across North America. It has therefore become important for federal management to gain an understanding of total use on these trails. However, there has never been a formal attempt to estimate hiking on these long, backcountry trails. This paper presents an approach that utilizes two survey instruments (exit-site tallies and a trail-user ...

As refractive surgery changes the properties of the cornea and the lens, concerns about refractive or intraocular lens (IOL) procedures in humans exposed to extreme situations have been raised. Early in the 1990s, it was reported that incisional refractive surger...
