Abstract: The present disclosure processes a user's medical data for each year to be input to a machine learning device for predicting dementia, and a data set composed of optimal features is constructed. The optimal features include at least information on the user's disease history, and the user's medical information for each year in the last 7 years or less. Precise prediction and diagnosis of dementia may be made by constructing the optimal features identified through experiments in the user's medical data for each year. Since the experimental results show that the prediction results of observing a disease history of 7 years or less may be the best, rather than observing medical information for a long period of time, the appropriate criteria may be suggested for predicting dementia.

Abstract: A method for detecting whether a user's roaming has occurred is provided. The method may be performed by a roaming detection server and comprises receiving location data of the user from a terminal of the user, determining whether the user may be located indoors by using the location data of the user, and determining a use of a building in which the user may be located using use information of the building based on the user being located indoors, and detecting whether the user's roaming has occurred based on a predetermined condition, wherein it may be detected that the roaming has occurred based on the building in which the user may be located not being a building of a predetermined use.

Abstract: A method for processing handover to provide IP mobility for mobile user equipment, a system thereof, and a Mobile IP (MIP) client device using the same method. The method processing handover at a home agent in a heterogeneous protocol mixed network includes: at a home agent, creating a Proxy Mobile IP (PMIP) tunnel when user equipment accesses a PMIP network; at the home agent, creating a Client Mobile IP (CMIP) tunnel when a CMIP network is accessed due to handover of the user equipment; and at the home agent, severing the PMIP tunnel when the user equipment completes performing handover.
