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: The present invention provides a migration control method in a distributed cloud environment in which a migration control device controls migration of a virtual machine to allocate a resource in a distributed cloud environment including: measuring and monitoring a resource usage amount of virtual machines of a data center in the unit of time; detecting a hotspot in which the measured resource usage amount exceeds a predetermined threshold value and selecting a target virtual machine to be migrated in a server which is detected as the hotspot, and performing migration of the virtual machine from the server which is detected as the hotspot to a server to which the virtual machine will be moved in consideration of the resource usage rate of the target virtual machine.

Abstract: Provided is a method and apparatus for detecting an intrusion in a cloud computing service. An elementary detector may monitor a virtual machine provided by a cloud computing service, and may generate a raw alert based on a result of the monitoring. An intrusion detection system (IDS) dispatcher may determine occurrence of an intrusion into the cloud computing service by comparing the raw alert and a local database. The IDS dispatcher may generate a hyper alert when it is determined that the intrusion has occurred. An intrusion detection system (IDS) manager may determine the occurrence of the intrusion by comparing the hyper alert and a global database.
