Abstract: The present invention relates to an emergency psychiatric mental state prediction model-based emergency telepsychiatry system and a method for operating the same. The emergency telepsychiatry system can include a collection unit for collecting real-time mental health symptoms and medical and family history data of a patient, a prediction unit for predicting a psychiatric mental state of the patient from the collected real-time mental health symptoms and medical and family history data, and a transmission unit for providing the predicted psychiatric mental state of the patient.

Abstract: A method for sharing a secret key between a source node and a destination node includes (a) adding, at each forward intermediate node, a secret key between the forward intermediate node and a node before the forward intermediate node to the secret key sharing request message; (b) generating a shared secret key between the source node and the destination node from the secret key between the forward intermediate node and the node before the forward intermediate node added in the secret key sharing request message; (c) adding, at each backward intermediate node, a secret key between the backward intermediate node and a node before it to the secret key sharing response message; and (d) generating the shared secret key between the destination node and the source node from the secret key between the backward intermediate node and the node before it added in the secret key sharing response message.

Abstract: The present invention relates to a sensor network, and more particularly, to a device and method for managing sensor nodes, in which with respect to predictable events and unpredictable events detected by sensors, the predictable events can be managed as existing policies and the unpredictable events can be managed by receiving policies for the unpredictable events from peripheral sensor nodes or peripheral sensor networks, i.e., both predicted events and unpredicted events can be intelligently managed. According to the method device for managing events detected by sensor nodes according to the present invention the present invention, in the case where unpredictable events are detected, policies for the detected unpredictable events received automatically from peripheral sensor nodes or peripheral sensor networks, so that both predictable and unpredictable events can be managed.
