Abstract:
A provided is an inter-layer group communication method in a content centric networking environment. The inter-layer group communication in a content centric networking (CCN) environment among the embodiments includes: a step that a CCN router receives an attendance message having a service name which a user node subscribes from the user node; a step that the CCN router transmits the attendance message toward a rendez-vous point which is mapped with the service name and forms a group sharing tree; a step that the CCN router receives a content request message having a content name which the CCN router wants to receive from the user node through the service; and a step that the CCN router transmits the content request message through uplink and downlink interfaces which are connected to the group sharing tree. [Reference numerals] (AA) Start; (BB) End; (S310) User node generating an attendance message including a service name; (S320) Transmitting the attendance message to a CCN router; (S330) Transmitting the attendance message toward a rendez-vous point; (S340) Generating a group sharing tree based on the rendez-vous point; (S350) CNN router receiving the contents request message and adding the corresponding interface to a reception interface list of PIT; (S360) Interface not transmitting the contents request message exists?; (S380) Transmitting through an interface existing on the reception interface list of PIT when receiving the requested contents; (SS370) Transmitting the contents request message and adding the corresponding interface to a transmission interface list of PIT
Abstract:
PURPOSE: A hybrid porous structure, a method for manufacturing the hybrid porous structure, a separating membrane including the hybrid porous structure, and a water treatment device including the same are provided to function as a separating membrane for variety of separating target materials. CONSTITUTION: A hybrid porous structure(10) includes a non-porous template(2), an ionic polymer coating layer(1), pores, and necks. The necks are in connection with pores arranged at the center part of a spherical body. A method for manufacturing the hybrid porous structure includes the following steps of: forming a laminate by laminating a plurality of spherical particles for forming macropores to be bordered in a three dimensional direction; forming a non-porous template by injecting a material for forming the non-porous template and curing; forming a non-porous template with densely laminated spherical macropores by dissolving and removing the spherical particles for forming macropores; and coating the inner surface of the macropores of the non-porous template with an ionic polymer solution to form an ionic polymer coating layer, and forming the hybrid porous structure.

PURPOSE: An organic/inorganic-hybrid layered structure, a manufacturing method of superhydrophobic using thereof, or a super-hydrophilic surface are provided to manufacture an organic and inorganic hybrid layered structure without special equipment through a simple process. CONSTITUTION: An organic/inorganic-hybrid layered structure is formed on a substrate and includes a polymer electrolyte layer which has curved surface and inorganic nanostructure which is formed on curved surface of the polymer electrolyte layer. The organic and inorganic hybrid layered structure additionally includes surface energy gradient material on the inorganic material nanostructure so that the structure can have ultrahydrophobicity or super hydrophilicity. A manufacturing method of ultrahydrophobic or super hydrophilic surface comprises the following steps: forming polymer electrolyte layer on a substrate; forming polyelectrolyte/inorganic nanoparticle composite layer which has surface roughness by forming inorganic nano particles on the polymer electrolyte layer; and forming an organic and inorganic- hybrid layered structure by removing the polyelectrolyte from the multiple layers.

PURPOSE: A structure, a device including the same, and a method for manufacturing the same are provided to implement the planarization of a substrate with a concavo-convex part by using self-diffusive polymers. CONSTITUTION: A concavo-convex part is formed on the surface of a substrate. The polymer thin film is coated on the substrate. The polymer thin film includes a double layer comprised of a pair of a positively charged polyelectrolyte and a negatively charged polyelectrolyte. The part of the positively charged reactor included in the positively charged polyelectrolyte and the part of the negatively charged reactor included in the negatively charge polyelectrolyte are electrically neutral.
