Abstract: An operating room allocation apparatus may be provided. The apparatus according to an embodiment of the present disclosure may include: an information obtaining unit configured to obtain information about patient's entry and exit times in each operating room; a first calculation unit configured to calculate a utilization rate of the operating room for each certain time period based on the patient's entry and exit times; and a second calculation unit configured to receive certain time information from a user and calculate an average utilization rate by time period in the received time information.

Abstract: A repeater including a downlink signal processor, which receives a downlink frame from a radio access station (RAS) and transmits the downlink frame to a portable Internet terminal, and an uplink signal processor, which receives an uplink frame from the portable Internet-terminal and transmits the uplink frame to the RAS, is provided, including: an ID storage unit to store identification (ID) information of the repeater; switches to switch a signal transmission path so that the downlink frame can be transmitted to the portable Internet terminal through the downlink signal processor, or the uplink frame can be transmitted to the RAS through the uplink signal processor; and a switch control unit to control the switches such that the ID information of the repeater is inserted into part of the downlink frame and the downlink and uplink frames are transmitted.

Abstract: Disclosed is a method of measuring the throughput of uplink data in a WiBro repeater, the method including the operations of: (a) extracting a plurality of tiles from a predetermined number of symbols that are collected over a plurality of times by performing frequency conversion on the uplink data; (b) calculating power values for the respective extracted tiles; (c) calculating an average noise value from the calculated power values; (d) calculating a threshold value, which is used to identify noise, from the average noise value, and calculating the number of tiles having power values more than the threshold value; and (e) calculating the throughput by estimating based on the number of the tiles the number of subchannels carrying data.
