Abstract:
Disclosed is a three dimensional (3D) navigation system for contents guide and a method thereof. The contents guide navigation system includes a contents classification module to classify contents based on at least one tag defined in the contents, and a navigation module to provide a list of the classified contents via a 3D guide screen constituted by an x axis, a y axis, and a z axis. Here, the navigation module links the list of the classified contents to the x axis, the y axis, and the z axis, each of the x axis, the y axis and the z axis being linked on different standards.
Abstract:
The present invention relates to a method of manufacturing a ferroelectric thin film device, and, more particularly, to a method of manufacturing a ferroelectric thin film device having high crystallinity, good surface roughness and high deposition efficiency through on-axis type sputtering, and to a ferroelectric thin film device manufactured using the method. The method of manufacturing a ferroelectric thin film device includes: depositing an SrRuO3 (SRO) thin film on an SrTiO3 (STO) substrate; and depositing a BiFeO3 (BFO) thin film on the deposited SRO thin film, wherein each of the thin films is deposited in a state in which the STO substrate is isolated from the ground. The method of manufacturing a ferroelectric thin film device is advantageous in that a ferroelectric thin film has a uniform surface, thus greatly decreasing the amount of leakage current and increasing remnant polarization.
Abstract:
Disclosed is a technology of encoding haptic information on images or decoding haptic information from images. The method of encoding the haptic information on the images according to the present invention includes: generating haptic information; generating encoding target data by using the haptic information and header information associated with the haptic information; and generating an encoded image by encoding the encoding target data by using a least significant bit (LSB) of byte data of each of the original image pixels. As a result, the present invention can simply encode/decode the haptic information while maintaining an original image format.
Abstract:
The present invention relates to an aspect-level news browsing service system and method for mitigating effects of media bias, which group news articles having different aspects on the same event on the basis of aspects, and simultaneously provide grouped news articles to users. The aspect-level news browsing service system may include a user terminal for accessing a news service server over an Internet and receiving aspect-level news article information from the news service server. A news provision server may transmit news article information to the news service server over the Internet. The news service server may extract aspects from the received news article information, classify the news article information based on the extracted aspects, and may transmit the aspect-level news article information to the user terminal depending on the aspects to enable the news article information to be displayed. The Internet may be configured to connect the user terminal to the news service server.

Abstract:
The present invention relates to a method of systematically and synthetically accessing modality conversion that is an important part in the contents adaptive conversion process of a universal multimedia access system. The present invention provides an effective method of solving a problem, which is incurred at the time of modality conversion and still remains as one of difficult problems incurred during adaptive contents conversion. For this purpose, the present invention includes overlapped contents modeling newly proposed to determine modality conversion, a method of flexibly and clearly expressing and applying user preference for the modality conversion, and a resource allocation method of distributing resources among complicated contents based on the user preference. As a result, the integration of the above three methods provides a synthetic solution, particularly, to a problem incurred in the modality conversion and, generally, to a problem incurred in the adaptive conversion of contents.
Abstract:
A disk friction clutch apparatus using a self-energizing effect is disclosed. The clutch apparatus includes a drive friction disk connected to a drive shaft, a driven friction disk connected to a driven shaft, a push member configured to press the driven friction disk against the drive friction disk at an engagement position of a clutch, and an operation unit configured to shift the push member from the release position of the clutch to the engagement position. The operation unit is operated to increase a force of the push member to press the driven friction disk when the push member located at the engagement position of the clutch receives a force of rotating the drive shaft. Since the clutch apparatus employs a self-energizing effect, it is possible to fasten the clutch with a small force.

Disclosed herein is a vibration generation module capable of generating inertial and impact vibrations. The vibration generation module includes a magnetic force generation unit, an elastic force provision unit, a permanent magnet, a contactor, and an impact transmission panel. The permanent magnet is configured such that when periodic electrical energy having a specific duty or voltage is supplied to the magnetic force generation unit, the permanent magnet alternates between a position in which the permanent magnet is completely spaced apart from the magnetic force generation unit and a completely lowered position in which the permanent magnet collides with an upper surface of the magnetic force generation unit, and such that periodic electrical energy having another specific duty or voltage is supplied to the magnetic force generation unit, the permanent magnet alternates between a position in which the permanent magnet is partially spaced apart from the magnetic force generation unit and a partially lowered position in which the permanent magnet is close to the upper surface of the magnetic force generation unit.
