Disclosed is a computer-readable medium including a computer program including encoded commands. The computer program is configured to cause one or more processors to perform operations for optimizing a database application when the computer program is executed by the one or more processors of a computer system and the operations include: operation for receiving a query including a bind parameter from an application source; operation for obtaining information related to the bind parameter included in the received query; and operation for rewriting the received query by reflecting the obtained information related to the bind parameter within the received query as hint information.

Optimization technique for database application

Disclosed herein is a compound composition for a vehicle interior material using a natural fiber, which has use for enhancing physical properties, such as shock resistance, tensile strength, flexural strength, elongation, flexural modulus of elasticity, and heat deflection temperature, while realizing a reduction in weight of a vehicle. The compound composition is composed of a base resin obtained by mixing a high-fluidity polypropylene resin and a high-impact polypropylene resin, the base resin being a thermoplastic resin, a reinforcing filler that is a lightweight, eco-friendly, and low-density natural fiber, an impact modifier that is ethylene-propylene-octene rubber, an inorganic filler that functions as a nuclear agent, and a maleic-anhydride compatibilizer.

The present invention relates to a satellite IP multicasting system and method for constructing an IP multicast network by a unit of internet node having a router for subscriber connection or a switch, and for transmitting a multicasting packet transmitted from a content provider into a local IP multicast network via a satellite. The satellite IP multicasting system features a backbone network, a content provider, a satellite network and a local network. The local network, which is interworked with the backbone network, is configured to multicasting protocol at a router or a switch, performs reverse path forwarding by static multicasting routing setup on a router or a switch connected to the satellite network via Ethernet and on a subscriber router or by IP designation of the same sub-net with source address of IP header of the multicast packet to an output port of a satellite data receiver and a port of a router connected to the satellite data receiver, and transmits the multicast packet into a terminal client.
