Provided are a system and method for determining whether to provide service and a content of the service based on ubiquitous-based context information. The method includes the steps of registering at least one context-aware service (CAS); determining whether sensors associated with the CAS are registered; when all the sensors are registered, checking all contexts associated with the CAS; upon receipt of a CAS request, receiving context information from the sensors and determining whether the context information satisfies the contexts; and providing the CAS if the context information satisfies at least one of the contexts. With the flexible engine determining whether to provide service corresponding to a current context even though all context information constituting the CAS is not collected, information is quickly provided upon receipt of a service request from a user.

A method and device for local domain management are provided and include a local domain authority device. The local domain authority (LDA) device includes a location limited channel (LLC) interface for transmitting and receiving information of devices which are positioned within a limited location and a (LDA) module for authenticating a device which is selected as a member of a domain from the devices, transmitting device authentication information corresponding to the domain, to the authenticated device via the LLC interface, and registering the authenticated device as a member of the domain. The method and device provide an easy and secure means for domain management.

Disclosed is an environmentally benign and simplified method for preparing aromatic dicarboxylic acid. In the disclosed method, a mixed solvent composed of aromatic mono-carboxylic acid and water, instead of conventionally used low molecular weight carboxylic acid such as acetic acid, is used as a reaction solvent for an oxidation process; manganese and a small amount of transition metal element are used as catalysts; and carbon dioxide is used as a reaction stabilizer. Accordingly, it is possible to improve the yield and selectivity of the aromatic dicarboxylic acid.
