Abstract: The present invention relates to a solution reaction apparatus and solution reaction method using the same, and more particularly a solution reaction apparatus and a solution reaction method using the same, wherein a reaction vessel is made by using a sealing member, a reaction vessel forming member, and a substrate serving as the bottom part of the reaction vessel so as to cause one side of a reaction solution only to contact the solution, thereby adjusting the temperature of the substrate differently from the temperature of the solution. The solution reaction apparatus of the present invention can control temperature of the substrate and temperature of the reaction solution separately, thereby it can control the temperature of the solution above the boiling point of the solution, and can react the solution while constantly maintaining the concentration of the solution by the solution circulatory device. Accordingly, it has an effect of freely forming various nanostructures on the substrate.

Abstract: Disclosed is a method of efficiently inviting a subscription to contact information, the method including receiving a subscription invitation request of particular contact information of a first client from the first client; and determining whether a condition for allowing the subscription to the particular contact information is included in the subscription invitation request, and transmitting a subscription request containing address information by which the condition and the particular contact information can be received to a second client when the condition is included. Accordingly, it is possible to provide a communication service at a high speed in a communication system supporting various types of communication services without a waste of resources, power, or memories. Also, it is possible to provide a data transmission/reception method capable of easily and quickly providing a CAB service according to a selection by user's intention.

Abstract: A method and apparatus for providing a communication history of a terminal in a Session Initiation Protocol/Internet Protocol (SIP/IP) core network. When a user having a plurality of terminals sends a subscribe request for a communication history of the terminals to a server, the server transmits all communication history information associated with the plurality of terminals to any one of the terminals each time the communication histories associated with the terminals are newly registered. The terminal, which has received the communication history information, can request and receive presence information of a corresponding terminal, which is included in the communication history information, if needed.
