The cadastral system provides land ownership information by registering and representing land boundaries on a map. The current cadastral system in Korea, however, focuses mainly on the management of 2D land-surface boundaries. It is not yet possible to provide efficient or reliable land administration, as this 2D system cannot support or manage land information on 3D properties (including archi...

Underground railway stations are known to have elevated particulate matter (PM) loads compared to ambient air. As these particles are derived from metal-rich sources and transition metals may pose a risk to health by virtue of their ability to catalyze generation of reactive oxygen species (ROS), their potential enrichment in underground environments is a source of concern. Compared to coarse (...

A wireless underground sensor network (WUSN) is defined as a network of wireless sensor devices in which all sensor devices are deployed completely underground (network sinks or any devices specifically for relay between sensors and a sink may be aboveground). In hybrid wireless underground sensor network (HWUSN), communication between nodes is implemented from underground-to-air or air-to-unde...

Maximising space in our urban towns and cities remains one of the great challenges of the future. As the need to protect existing green areas grows amid ever increasing demands for more homes and work places, mass transit systems and modern infrastructure, so new approaches must be found to better utilise space available. Improved use of underground space offers new and exciting opportunities f...

Underground displacement monitoring is a key means to monitor and evaluate geological disasters and geotechnical projects. There exist few practical instruments able to monitor subsurface horizontal and vertical displacements simultaneously due to monitoring invisibility and complexity. A novel underground displacement 3D measuring sensor had been proposed in our previous studies, and great eff...

Since the early 1990s we have observed a wide media coverage of voguingas an underground cultural expression American LGBT community. When overflowing Hallem’s borders, voguingbecame act resistance that impresses on body subjectivities held back by modern rationalism. Today, occupying different spaces, voguersteach us new performative textualities can be reconfigured in gestural memory, allowin...

We propose a rescue robot sensor network system in which a teleoperated rescue robot sets up a wireless sensor network (WSN) to gather disaster information in post-disaster underground spaces. In this system, the rescue robot carries wireless sensor nodes (SNs) and deploys them between gateways in an underground space on demand by the operator’s command to establish a safe approach path before ...

Dissatisfaction with work boot design is common in the mining industry. Many underground coal miners believe their work boots contribute to the high incidence of lower limb injuries they experience. Despite this, the most recent research to examine underground coal mining work boot satisfaction was conducted over a decade ago. This present study aimed to address this gap in the literature by as...

With the fast development and utilization of underground space resource in cities, the spatial distribution of urban underground pipelines becomes more and more complex. How to efficiently utilize the latest technology, realize underground space resources' management, visualization, layout optimization and mine applications, are challenging issues in current digital city development. Taking int...
