A first Bluetooth terminal having a short range communication module that is set as an anchor searches for a peripheral Bluetooth terminal and transmits information of the found Bluetooth terminal to a place management server. The place management server updates place information of a user of the found Bluetooth terminal to place information of the first Bluetooth terminal and transmits the updated place information to the found Bluetooth terminal.

Communication terminal, place management server, and method of detecting place information thereof

A system for providing spatial-based context-aware service includes a database configured to store a geocontext including spatial information, one or more contexts, and sensor data; a sensor/context catalog server configured to manage meta data of the contexts and the sensor data; a context processing server configured to generate a list of contexts applicable to the mobile device based on the sensor data and the meta data upon a receipt of the sensor data from the mobile device; a geocontext search server configured to search the database for candidate geocontexts appropriate for the user of the mobile device by using the location information of the mobile device and the list of contexts; and a context-aware management server configured to generate a list of recommended services by executing the searched candidate geocontexts.

Method and system for providing spatial-based context-aware service

A vessel block arranging device extracts image information on a vessel block loaded on a transporter, and determines whether to arrange the vessel block in an area in which the vessel block will be arranged by using location information of the arranged vessel block in the area and extracted image information, thereby reducing errors caused by determining the vessel block arrangement.

Device and method for arranging block of vessel

An apparatus and method of preventing a collision of vehicle in a crossroad are disclosed. The apparatus includes: an information generating unit installed at each of roads near the crossroad for generating real-time vehicle information by integrating vehicle's information including a speed and a position provided from the vehicles on each of the roads and traffic sign information; and an information collecting and providing unit for providing the traffic sign information to the information generating unit, collecting vehicles' information in real-time from the information providing means of a predetermined road near the crossroad, storing the collected information, and providing the collected information to vehicles approaching the crossroad through another roads for the vehicles to predict a collision in the crossroad.
