Abstract: An on-line social networking method is presented based on a third party's evaluation, wherein third party's opinions are taken into consideration in constructing a community or building a network using the Internet. A network for only those users who can trust one another is guaranteed, and thus network quality is enhanced and a variety of incidents prevalent in the Internet are prevented. For this purpose, a server of an Internet website is employed in providing a social networking module, a first member terminal group for requesting a friend relationship, a second member terminal group for determining whether to approve the friend relationship, and a third member terminal group for generating evaluation information on an evaluation target member. The third member terminal group is an advisor group of the second member terminal group.

Abstract: Disclosed herein are a highly porous ceramic having a high porosity of not less than 60% and a pore density of not less than 108 pores/cm3 fabricated from expandable microspheres and a preceramic polymer, and a method for fabricating highly porous ceramic. The method for fabricating highly porous ceramic from expandable microspheres and a preceramic polymer comprises the steps of: homogeneously mixing a preceramic polymer powder and expandable hollow microspheres, if necessary, a ceramic powder, and molding the mixture to form a molded body; heating the molded body to expand it; curing the expanded molded body; and pyrolyzing the cured molded body. Since the highly porous ceramic has a higher porosity and pore density than conventional porous ceramics, it can be suitably used for various high temperature structure materials, kiln furniture, bulletproof materials, shock-absorbing materials, insulating materials, refractory materials, lightweight structure materials, etc.

Abstract: Microporous ceramic materials used in structural materials, high-temperature filters, electrode materials or preform materials for infiltration by homogeneously mixing and molding a ceramic precursor powder polymer. The powder is saturated by introducing fluid to a pressure vessel. The fluid is super saturated by adjusting pressure in the vessel. Micropores are formed in the molded bodies by evolving the fluid from the molded bodies by heating and hardening the molded bodies. The hardened molded bodies are heated to pyrolysis. Pore characteristics (e.g., pore size and pore size distribution) suitable to target materials are controlled by adjusting pressure at a non-critical state without requiring additional processes or devices.
