The present invention relates to a radiation amount estimating method, and more particularly, to a radiation amount estimating method of an MRI based composite image using a lookup table. To this end, the object of the present invention is to provide a radiation dose estimating method of an MRI based composite image using a lookup table including: generating a lookup table representing a linear attenuation coefficient of a region of interest from a CT image (S); photographing at least two of a T1 image, a T2 image, and a PETRA image of a patient from MRI equipment (S); generating a composite image by superimposing the photographed images (S); representing a border line of the region of interest in the composite image to distinguish the region of interest (S); designating the linear attenuation coefficient of the lookup table in the distinguished region of interest (S); and estimating a radiation dose based on the composite image to which the linear attenuation coefficient is designated (S).

An air conditioning equipment includes a housing comprising a heat exchanger therein, a water container mounted to, and dismounted from a receiving portion of the housing and to collect a condensate generated by the heat exchanger, and a valve configured to selectively open and close a discharge port by being interfered with a portion of the water container according to the mounting and the dismounting of the water container to or from the receiving portion of the housing. The valve is inserted within the receiving portion of the housing through the discharge port in order to reduce a protruded length that is interfered by the portion of the water container.

The present invention relates to a data transmission/receiving method and apparatus in a relay communication system. In particular, the data transmission/receiving method through a backhaul link between a base station and a relay node in a relay communication system comprises: composing a backhaul subframe including a control signal transmission period to which a control signal is allocated and a backhaul signal transmission period to which a backhaul signal is allocated and then allocating the backhaul signal; transmitting configuration information about the backhaul subframe, the information containing symbol position or size data of the backhaul signal transmission period, to the relay node through an upper layer signal; and transmitting the backhaul signal having been allocated through the backhaul subframe to the relay node.

Signal transmission method and apparatus in a relay communication system

The present invention relates to a method and an apparatus for transmitting and receiving data in a relay communication system. The method and the apparatus allocate resources by dividing backhaul link resources into plural partitions, and then transmit and receive data. The data transmission method of the invention comprises the steps of: allocating a certain number of initial OFDM symbol transmission periods in a sub-frame of a downlink channel to a control channel that transfers the control information of the terminal, wherein data is transmitted from a base station to a relay or terminal through the downlink channel; dividing the resource blocks excluded from the control channel of the sub-frame into at least two partitions based on frequency domain; determining whether or not each divided partition is allocated to the relay or terminal as resources; and allocating data to the determined partition in order to transmit the partition to the relay or terminal through the downlink channel, wherein the partition determined for the allocation of resources to the relay is allocated to the relay through time division multiplexing (TDM) or frequency division multiplexing of both control and data channels of the relay.

The present invention provides a method for transmitting/receiving data to/from a relay. The data transmitting/receiving method comprises the steps of: enabling the relay to receive data on an nsubframe of a downlink from a base station; determining the position of the subframe of an uplink to which data is to be transmitted, if any data to be transmitted exists, wherein the position of said subframe is determined as the (n+k)subframe, wherein said k is determined by the value of said n and by information on a preset HARQ; and transmitting the data on an (n+k)subframe of the uplink.
