Abstract: In a message retransmission apparatus, a storage unit stores store a plurality of non-transmission messages, each being assigned a respective destination device to which delivery, over a communication network, is indicated as unsuccessful. A calculation unit sets a respective retransmission time for each of the plurality of non-transmission messages. A communication unit retransmits a given non-transmission message at a given respective retransmission time a given respective destination device, and, in response to an indication that delivery of the given non-transmission message over the communication network is successful, retransmits the other non-transmission messages to the respective destination devices without waiting for the respective retransmission times thereof.

Abstract: Provided is a constitutional disease pattern determination apparatus including a calculator to calculate a first deficiency and excess index and a first cold and heat condition index of a user based on clinical information on the user, and a determiner to determine, based on a first reference table corresponding to a first constitution, a first constitutional disease pattern corresponding to the first deficiency and excess index and the first cold and heat condition index among a plurality of constitutional disease patterns included in the first reference table, wherein the first constitution is a constitution classified to correspond to the user based on a Sasang constitution.
