Abstract: Provided is a sensory substitution apparatus and method that combines two or more pieces of multi-sense sensory information to be converted into different multi-sense sensory information, in which received pieces of multiple information are combined to suit sensory characteristics of the user's body and efficiently transmitted to a different sensory organ. According to the present invention includes: receiving input sensory information; classifying the input sensory information; calculating an importance of each of individual sensory information; determining a target sense for which part or all of the individual sensory information, of which an importance is calculated, is to be converted into a new sensory signal incongruent with the corresponding individual sense; and converting the input sensory information into target sensory information to be transmitted to the determined target sense which is an organ.

Abstract: Provided are a hyaluronic acid derivative for liver-targeting delivery via intravenous injection of cells and a preparation method thereof. More particularly, provided are a preparation method of a hyaluronic acid derivative capable of modifying the surface of cells and also having biocompatibility, biodegradability, and liver-targeting deliver property, and use of the hyaluronic acid derivative prepared thereby as a liver-targeting cell delivery system.

Abstract: The present invention is related to an apparatus that can include a portable computer with a keyboard apparatus and/or a docking station. A keyboard apparatus can be secured to a main body of the computer system and selectively enable users to input data when the computer (e.g., web pad) is turned on. The keyboard apparatus can be used for a portable multi-type computer with web pad function and notebook personal computer. The docking station can include a stand pivotably coupled to a dock that can receive the main body with/without the keyboard apparatus. The docking station can support selective display in a portrait or landscape mode. Further, combinations of the portable multi-type computer allows unique versatility of viewable options of a display of the main body (e.g., web pad) when with the keyboard apparatus and/or docking station.
