Abstract: A method of organizing a user-customizable content adaptation object being performed on a user-customizable content adaptation object organizing server, the server being coupled to a user terminal, the method includes: (a) classifying at least one resource based on a context category; (b) selecting at least one classified content adaptation object based on a context to associate the at least one classified content adaptation object with an object collector, the at least one classified content adaptation object respectively corresponding to a computer-executable object, and being capable of receiving a remote response by the user terminal or being applied to the user terminal; (c) generating a collector layout page including the at least one content adaptation object in the object collector; and (d) providing the generated collector layout page to the user terminal.

Abstract: A method of providing a context based service is performed by a user terminal. The method includes: generating a user profile about at least one entity; providing user profile characteristic information obtained or inferred from the user terminal associated with the at least one entity; and controlling to provide a user description generated based on the user profile and the user profile characteristic information to a recommendation engine for a required service if a recommendation of a context based service is required to the at least one entity, the recommendation engine performing a service recommendation according to a situation of the at least one entity.

Abstract: Provided is a method for automatically obtaining position information of virtual resources such as a network device in a virtual space such as a house, an office, and the like. The method for mapping position information of a virtual resource includes recognizing virtual resources virtualized according to services or characteristics unique to devices in a particular space, and collecting virtual resource information including internal states and providing services of the virtual resources, obtaining event occurrence information regarding the virtual resources by using the virtual resource information, when an event occurs in at least any one among the virtual resources, obtaining image information regarding the particular space, and obtaining position information regarding the virtual resources by using the event occurrence information and the image information.

Abstract: Provided is a method for providing a collaborative service based on virtual resources including generating virtual resources virtualized according to unique services or characteristics of devices connected through an assist gateway in a specific space and collecting virtual resource information including internal states of the virtual resources and services provided by the virtual resources, configuring a collaborative service with respect to the virtual resources using the virtual resource information, and generating a control command with respect to at least one or more virtual resources defined in a requested collaborative service.

Abstract: If a content creator that creates content and a service provider that provides the content are different, the content should be reconfigured and provided. In order to provide an interface suitable for a user environment, only a limited user environment should be considered. Thus, flexibility is low when an adaptive user interface is provided. It is possible to provide a user interface, independently of the relevant designer, by redefining content, a usage environment, and a relation between a page and a service provider and dynamically providing a user interface suitable for the user environment.

Abstract: Disclosed are a relay and method for protecting a transformer, and a transformer protecting system having the same. In the present disclosure, whether a transformation ratio of a transformer has been correctly set or not may be determined based on an inner algorithm. If it is determined that the transformation ratio of the transformer has been incorrectly set, a user may be informed to reset the transformation ratio. This may prevent a malfunction of the relay when the system is operated, and may enhance a system stability.

Abstract: The present disclosure relates to a digital protection relay and an operation method of the digital protection relay for enhancing the operation of a frequency change rate relay element (81R) thereof, and the digital protection relay and an operation method thereof may calculate a plurality of different frequency change rates from the measured frequency and use a value of the frequency change rate selected based on a predetermined criteria in the control of a relay operation, thereby providing an effect of enhancing reliability for the operation of the frequency change rate relay element.

Abstract: A device and a method for processing an input data of an protective relay, even in case that data stored in an accumulation buffer of the protective relay is damaged due to noises, etc., that can recover it and carry out a normal measurement are provided, the invention includes a digital signal processing part comprising inputting a sampled digital data to a digital signal processing part, counting and accumulating frequency of the inputted data, comparing the accumulated value with a value of a period, inputting a value of an update accumulation buffer to a measurement accumulation buffer and initializing the update accumulation buffer if the counted accumulation frequency is equal to the value of one period; and performing an RDFT (Recursive Discrete Fourier Transform) operation on the inputted digital data to dually buffering the measurement accumulation buffer and the update accumulation buffer.

Abstract: A digital protection relay is provided. An amplification factor is differently applied such that loss of a quantity of light with respect to an input signal is compensated for according to a length of an optical fiber cable for a point sensor. Thus, an occurrence of an arc can be more accurately detected, whereby power facilities and humans can be optimally protected from an arc accident.
