There is provided a system and method for providing a recommendation keyword having a high correlation with the content and reflecting the viewers' interests. A prospective viewer group of the content is generated by a broadcast time and a keyword of a specific broadcast content and a keyword set is generated by selecting keywords having a higher correlation with the content than a threshold value from among search words transmitted by the prospective viewer for a predetermined time period including a time before/after the broadcast time of the content. A keyword for each play time period is extracted from the keyword set by using the number of searches for each keyword therein for each play time period and the recommendation keyword for each play time period is stored, which is synchronized with play time of the content.

The present invention relates to a method and apparatus for controlling transmission power of the base station in a wireless communication system and includes calculating signal-to-noise ratio of a target component carrier and recovering the signal-to-noise ratio to be equal to or greater than a threshold by increasing a transmission power to a predetermined level and requesting, when the signal-to-noise ratio is less than a predetermined threshold, a neighbor base station to decrease the transmission power. According to the present invention, it is possible to suppress the inter-cell interference and improve channel utilization efficiency, resulting in improvement of the throughput of the wireless communication system.

A method and apparatus for concentrating and recovering ethylene from the off-gas from an apparatus which produces gasoline, propylene and the like by fluidized catalytic cracking (FCC) of heavy oils such as atmospheric residue, generated in a crude oil refining process, is provided. The method and apparatus can reduce the amount of ethylene rinse in the subsequent ethylene displacement desorption process by increasing the ethylene purity of a raw material gas and reducing the concentration of weakly adsorbing components in the raw material gas and can reduce the loss of a desorbent during a distillation process for separating the desorbent from the weakly adsorbing components. Thus, ethylene can be recovered from the off-gas from fluidized catalytic cracking of heavy oils at high concentration and low cost.

The present invention relates to a method and a device for managing resources of a base station in a wireless communication system. The method comprises: calculating an average resource use of serving resources, which are used as downlinks from a serving base station to a plurality of communication terminals; selecting one of the communication terminals, which has a maximum interference from a neighbor base station, if the calculated average resource use exceeds a preset threshold; and making a reservation for at least one of neighbor resources used as downlinks from the neighbor base station, the at least one neighbor resource corresponding to the serving resource for the selected communication terminal, so that the neighbor base station may decrease transmission power in the at least one neighbor resource. According to the present invention, since the base station makes a resource reservation so that transmission power may be reduced in at least one of the neighbor resources of the neighbor base station, the interference, by the neighbor base station, to the serving resource for one of the communication terminals connected to the base station can be suppressed Accordingly, the base station in a wireless communication system can effectively manage resources.

An apparatus for mounting a seat belt retractor for a vehicle is capable of promoting the ease with which a seat belt retractor is mounted on a center pillar by a worker, and minimizing an amount of movement of the seat belt refractor towards the interior of a vehicle body in the event of a broadside collision.
摘要:
The present invention relates to protein antigens IcsP2 and SigA2 from Shigella that are common among numerous Shigella types and species and which can protect against shigellosis or other enteric infections when administered as vaccines. In addition, the present invention relates to antigens that are in common between Shigella species and enteroinvasive Escherichia coli (EIEC). The invention also relates to the use of antibodies raised against these antigens and of DNA probes for use in the diagnosis of Shigella and EIEC infections.
