Title: Method of portal service on Internet
Inventor: LIM YEONG HO
IPC: G06F17/30
Filed: 2000-03-23
Abstract: PURPOSE: An internet portal service method is provided to conveniently use the Internet by conveniently obtaining information of internet sites opened as each different language. CONSTITUTION: Information regarding English sites of non-English-speaking worlds is constructed in a database interlocked with a web server(S210). An internet user accesses a portal site through the Internet using user's own computer at a random time(S220). The portal service site transmits a web page including a retrieval request way of an English site to the computer of the user(S230). The portal site checks whether the user requests the retrieval of the English site(S240). In case that the user requests the retrieval of the English site through the retrieval request way, the portal site retrieves English sites suitable for retrieval conditions from the database(S250) and transmits the retrieved English sites to the computer of the user(S260).

Abstract: PURPOSE: A process of preparing a functional fiber by evaporating germanium water at low temperature and mixing the obtained evaporation residues with resin is provided. The obtained fiber has an antimicrobial property and a deodorizing effect and radiates far-infrared rays. CONSTITUTION: Mineral water containing germanium is concentrated to give evaporation residues, which are ground to a size of 0.2 to 1 micrometer and mixed with synthetic resin in a ratio of resin to residue of 90 to 99% by weight: 0.1 to 20% by weight. The synthetic resin is polyester, polypropylene, nylon, acrylic resin, acetate rayon or the like.
