The method includes the steps of detecting when a key for playing a multi-user game using a LAN is pressed and in response, setting a connection between the plurality of mobile terminals and implementing the game function, sending game information generated during the game to each mobile terminal and storing the game information, and applying the stored game information for the next round of game play.
Abstract:
An apparatus for vector-quantizing an image signal having a low transmission rate which includes a four-band linear filter para-unitary (LPPU) filter group for transforming an input image signal into transform coefficients which are represented by 4.times.4 frequency bands. A code modulator differential-pulse-code-modulates a direct current (DC) component among the transform coefficients output from the four-band LPPU filter group. A coefficient extractor extracts a predetermined number of low-frequency alternating current (AC) component coefficients from the transform coefficients output from the four-band LPPU filter group. A classifier determines a corresponding class, from a plurality of predetermined classes, using the low-frequency AC component coefficients extracted by the coefficient extractor, and outputs class information representing the determined class. A classified vector quantizer quantizes classified vectors of corresponding AC component coefficients input from the coefficient extractor according to the class information output from the classifier and outputs block position information, corresponding to an image block having a predetermined size, of a block matching the transform coefficients transformed by the four-band LPPU filter group, together with the classified-vector-quantized image data and the corresponding class information when the class information does not represent a particular class among the plurality of the predetermined classes, and outputs the classified-vector-quantized image data and the corresponding class information when the class information represents the particular class.

Abstract:
The present invention relates to a method for manufacturing a solid body having a superhydrophobic surface structure formed by using a surface treatment of a metal body, a replication process, and a polymer sticking phenomenon to increase efficiency of fluid transfer and prevent foreign materials from being accumulated in the tube, and a superhydrophobic fluid transfer tube using the method. The superhydrophobic fluid transfer tube includes a fluid guider and a solid body provided on a fluid contact surface of the fluid guider and has micrometer-scaled unevenness and nanometer-scaled protrusions. In the method, a plurality of nanometer-scaled holes are formed on a surface of a metal body through an anodizing process, a replica is formed by immersing the metal body provided with the nanometer-scaled holes in a non-wetting polymer material and solidifying the non-wetting polymer material, the solid body having the superhydrophobic surface is formed by removing the metal body and an anode oxide from the replica, and the solid body is provided to a fluid contact surface of a fluid guider for guiding a fluid.
Abstract:
Disclosed is a lactic acid bacteria culture of mung bean obtained by culturing lactic acid bacteria in a culture medium containing mung bean extract. The culture contains the mung bean extract and GABA (ϝ˜ Aminobutyric acid), so that it exhibits effects of promoting collagen synthesis and alleviating inflammation. Accordingly, the cosmetic composition containing the culture can be usefully used as a cosmetic composition for promoting collagen biosynthesis, preventing or improving skin senescence, anti-inflammatory and preventing or improving skin injury.
Abstract:
Provided are an image display apparatus with a frame rate conversion function and a frame-rate conversion method thereof. The image displaying apparatus includes a frame rate conversion (FRC) part which converts and outputs a frame rate of an input image signal depending on a motion of an image, and a display which processes the input image signal that is output from the FRC part to display on a screen. Therefore, a motion judder can be decreased so that an image quality can be enhanced and power consumption can be reduced.

Abstract:
Disclosed is a non-natural ceramide compound effective for a sphingosine kinase activator, and thus useful for a skin disease treating agent. The sphingosine kinase activator enhances production of sphingosine-1-phosphate to show various physiological activities provided by sphingosine-1-phosphate. The physiological activities include the effects of: controlling multiplication and differentiation of keratinocytes, multiplication of fibroblasts and collagen synthesis, resulting in treatment of wounds, recovery of damaged skin functions in atopic dermatitis and psoriasis; inhibiting wrinkles and skin irritation caused by ultraviolet rays, followed by improvement of wrinkles and inhibition of skin aging; and reducing skin atrophy, which is a typical side effect of local application steroids. Therefore, the sphingosine kinase activator is useful for a skin disease treating agent for treating skin wounds, wrinkles, atopic dermatitis, eczema, psoriasis, or skin atrophy caused by side effects of local application steroids.
