Abstract: A power supply and a plasma display device having the power supply is disclosed. The power supply reduces power used in a power factor correction unit and a DC converter by distributing the total power of the power supply between the power factor correction unit and the DC converter.

Abstract: Provided are a demand response method and system. A household demand response apparatus includes: a signal reception unit which receives a critical peak notification message; a display unit which displays the received critical peak notification message and displays an inquiry message inquiring whether to interrupt power supply during a time section in which a critical peak occurs; and a control unit which controls the power supply based on a response to the inquiry message.

Abstract: An apparatus is provided for collecting amniotic fluid from the uterus. In order to collect the amniotic fluid from the uterus through the external orifice of the cervix of a pregnant woman, an amniotic fluid collecting unit is adapted to bring a mouth, which is foldably formed at the upper end of an amniotic fluid collecting bag, into close contact with an end of the external orifice of the cervix. Thereby, the apparatus not only significantly decreases the risk occurring when a needle is directly inserted into the uterus in order to carry out the amniocentesis (amniotic fluid testing), but also eliminates pain and anxiety caused by the direct insertion of the needle.

Abstract: A superhydrophobic polymer fabrication is provided.
