An analog-to-digital converter includes a modulation unit and a digital signal generation unit. The modulation unit is disposed corresponding to at least one column line, and sequentially perform delta-sigma modulation on an analog input signal and at least one residue voltage to generate digital bit stream signals. The analog input signal is input through the at least one column line. The at least one residue voltage is generated by performing the delta-sigma modulation on the analog input signal. The digital signal generation unit generates a digital signal corresponding to the analog input signal based on the digital bit stream signals.

The present invention relates to a photographing device including a power transmission unit. The power transmission unit includes a frame unit which is connected to the second drive body, an adaptor unit which is connected to the frame unit and is selectively connected to the first drive body or the support body by external power, an actuating unit which operates the adaptor unit, and a power unit which transmits power to the actuating unit. According to the power transmission unit of the X-ray mammography device, since biopsy photography and tomography can be performed using only one power transmission unit, the weight and size of the rotating arm may be reduced, and the vibration and noise produced thereby may be reduced. Thanks to the simple operation mechanism of the power transmission unit, power loss may be reduced, and the durability of each component may be improved.

An error control coding (ECC) circuit includes a first decoder, a second decoder, and a controller. The first decoder receives encoded data comprising a first parity and a second parity. The first decoder decodes the encoded data to a first code by using the first parity. The second decoder is connected to the first decoder. The second decoder is configured to decode the encoded data when the first decoder is deactivated and decode the first code using the second parity when the first decoder is deactivated. The controller transmits a control signal to the first decoder and the second decoder to control the first decoder and the second decoder.

The present invention relates to a new use of inhibitors of leukotriene B4 receptor BLT2 for treating human cancers. More particularly, the present invention relates to a pharmaceutical composition for treating human cancers comprising BLT2 inhibitors and a method for treating human cancers using BLT2 inhibitors.The present inventors revealed the role of BLT2 as a survival factor of human cancers, such as bladder, prostate, pancreatic, and breast cancer and found that the BLT2 inhibitors can be used as anti-cancer drugs. The present inventors revealed that BLT2 has an important role in metastasis of cancer cells and angiogenesis of tumor and demonstrated that the anti-cancer activity of the BLT2 inhibitors is accomplished by inducing the apoptosis of cancer cells, inhibiting the metastasis of cancer cells, or inhibiting the angiogenesis of tumor.
