Abstract: Disclosed are a system and method for distributing a blog post based on personal networking, and a server to be applied thereto. The system includes a writer terminal unit, which makes a series of settings for forming a blog post containing contents posted by a writer through the writer's blog registered with an online community service, and then distributes the blog post to at least one or more acquaintances blogs registered to personal networking with the writer, sharer/distributor terminal units, which make setting for posting the blog post on the acquaintances blogs, or distributing the blog post to at least one or more other acquaintances blogs registered to personal networking with sharers/distributors, and a service management server, which differentially provides management authority for the blog post to each of the writer and the sharers/distributors, and integrally manages the blog post distributed to a plurality of blogs, based on a path along which the blog post is distributed.

Abstract: The present invention relates to an optical film comprising: a blended resin including 1) an acrylic copolymer resin containing an alkyl methacrylate monomer and a (metha) acrylic monomer containing an alicyclic or an aromatic ring, 2) a copolymer resin containing an alkyl methacrylate monomer, an aromatic vinyl monomer, and an acid anhydride monomer, and 3) a resin containing an aromatic or an alicyclic ring in the main chain of a polymer. The present invention also relates to a method for manufacturing the optical film, and a liquid crystal display device comprising the optical film. The optical film according to the present invention is excellent in heat resistance, optical transparency, mechanical strength, durability, and the like.

Abstract: The present invention relates to a retardation film that comprises a blend resin of 1) an acryl-based copolymer resin that comprises an alkyl methacrylate-based monomer and a cycloalkyl methacrylate-based monomer, and 2) a resin that comprises an aromatic ring or aliphatic ring in a polymer main chain, a method for manufacturing the retardation film, and a liquid crystal display device that comprises the retardation film. The retardation film according to the present invention has excellent heat resistance, optical transparency, mechanical strength, and durability.

Abstract: A broadcasting system where user's participation is allowed, additional information personalized for each of users/local areas/time is inserted into an AV and the AV including the additional information provides a user and a method of providing a personalized broadcasting service in the same are disclosed. The method of providing a personalized broadcasting service in a broadcasting system includes inserting additional information registered by a first user into an AV, and displaying the AV into which the additional information is inserted for a second user.

Abstract: The present invention provides a polymer particle and a method of preparing the same. More precisely, the invention provides a polymer particle having optimum impact strength and improved elastic recovery rate by forming the brush having softness on the surface of the monodisperse polymer particle by the anion dispersion polymerization using a conjugated diene monomer.

Abstract: A channel-switching apparatus and method in a digital broadcasting system omits conditional access control in logical channel-switching in one physical channel from processes that are executed for channel-switching in a digital broadcasting system, thereby reducing channel-switching time.

Abstract: A channel changing apparatus and method in a digital broadcasting system can reduce channel changing time by including a plurality of broadcast programs in one logical channel, and in response to channel changing, selectively displaying a corresponding program in the logical channel.
