The present invention relates to a system for estimating a degree of distraction based on unconstrained bio-information. The present invention provides a system for estimating a degree of distraction based on unconstrained bio-information, the system comprising: a degree-of-distraction measurement chair comprising a seating unit, a message transmission unit, a pressure detection unit, and a support unit, which are formed in this order from the top to the bottom thereof, wherein the pressure detection unit formed on the support unit comprises a smart sensor including three load cells arranged at three vertices of a triangular shape on a plane; and a mobile smart terminal configured to receive information regarding the degree of distraction from the message transmission unit of the degree-of-distraction measurement chair through the Bluetooth communication.

Degree-of-distraction estimation system based on unconstrained bio-information

A memory management apparatus for use in an open geographic information system includes a plurality of layers, each layer requiring a layer component, a disk buffer management component, a memory buffer management component and a spatial index management component; a layer collection component having a plurality of layer components, each layer component containing responsibility of managing all of the spatial data included in one layer accessed thereto through a data provider component; and a total memory management component. In the system the total memory management component manages totally a memory buffer to spatial data included in one or more layers, allocates a corresponding memory if each of memory buffer management components requests a memory buffer and frees a memory of a predetermined memory buffer management component when an available memory lacks.
