Abstract: The server of a communication system determines a communication growth level that is the level of growth of communication between one user and another user based on the cumulative count of mail send/receive events, and stores the determined growth level in the communication growth level Data Base. When the server receives a profile view request to view the profile of user A from the terminal of user B, the server determines the range of profile information to be opened for user B out of the profile of user A, based on the communication growth level of the pair of user A and user B stored in the communication growth level Data Base.

Abstract: An apparatus for measuring a propagation velocity of a pulse wave which is propagated through an artery of a living subject, the apparatus including an electrocardiographic-waveform detecting device which detects an electrocardiographic waveform from the subject, a pulse-wave sensor which is adapted to be worn on the subject and which detects the pulse wave from the subject, a time-difference determining device for determining a time difference between a first periodic point relating to the detected electrocardiographic waveform and a second periodic point relating to the detected pulse wave, and a propagation-velocity determining means for determining the propagation velocity of the pulse wave based on the determined time difference.
