Abstract: A mobile station adapted for channel switching comprises an input unit adapted to receive user input associated with selection of content. The mobile station also comprises a timer generating unit operatively coupled to the input unit, adapted to generate a timer related to transmission of a command derived from the user input to a content server in response to the user input. The mobile station also comprises a transmitting unit operatively coupled to the input unit, adapted to transmit the command derived from the user input to the content server in response to expiration of the timer. The mobile station also comprises a receiving unit operatively coupled to the transmitting unit, adapted to receive the content from the content server in response to receipt of the command derived from the user input by the content server.

Abstract: This invention relates to a technology of modifying low-molecular-weight bioactive substances with short in vivo half-life and low stability in order to achieve a stable and efficient in vivo delivery thereof. More specifically, the present invention relates to a stable bioactive substance-blood protein conjugate, wherein a low-molecular-weight bioactive substance is ex vivo conjugated with a specific functional group on a blood protein through a reactive group, the low-molecular-weight bioactive substance is available as a drug for treatment and prevention in mammals including human and selected from the group consisting of a natural substance; and a method of a stable and efficient in vivo delivery of the low-molecular-weight bioactive substance based on the use of the bioactive substance-blood protein conjugate.

Abstract: The present invention relates to a sustained release formulation comprising protein as an active ingredient, and a preparation method thereof. According to the present invention, the sustained release formulation contains protein drugs that are encapsulated in biodegradable hydrophobic matrices as pharmaceutically active forms by forming complexes with sulfated polysaccharides. The sustained release formulation prepared by the present invention can be used to effectively treat a disease without frequent injections by keeping the protein concentration at a sufficiently high level for a long period when injected in vivo once.
