Abstract: Described is a radially multi-branched polymer represented by the following formula (I): ABi (I), which includes a central molecule (A) to which side-branches (B) are bonded in at least three positions (i?3). Also described are methods for preparing a multi-branched polymer as well as a porous insulating film including a multi-branched polymer.

Abstract: Disclosed herein is a real-time auction method that is based on an auction server for performing a process of an auction and wired and wireless terminals of participants.

Abstract: A backlight module comprises an assembly of a rear substrate and a front substrate. A hermetic discharge gap is formed there between and mounted with power electrodes. The backlight module further comprises a discharge gas filled in the discharge gap and a plurality of fluorescent layers of different color emissions disposed on a surface of the assembly of the rear substrate and front substrate. The discharge gas is discharged by the power electrodes.

Abstract: Novel Saccharomyces Cerevisiae mutant strains are provided for producing human parathyroid hormone. The novel strains acre genetically disrupted in at least one of the genes encoding the yapsin family of proteases Yapsin 1, Yapsin 2 and Yapsin 3 and harbor a human parathyroid hormone gene in their genomes. Culturing the novel strains results in the secretion of intact hPTH into culture media at high yield.

Abstract: A device is for recovering superfluous photoresist material exhausted from a spin coater having a drive motor alternately operated at a high speed and a low speed at predetermined intervals. The device includes a solution collecting member into which superfluous photoresist material and cleaning solution are collected after a photoresist is coated onto a wafer and the wafer is cleaned during operation of the drive motor. The solution collecting member has a groove circumferentially formed therein to allow the superfluous photoresist material to flow therein. First and second discharge pipes communicate with the solution collecting member to drain the superfluous photoresist material and a cleaning solution and a third discharging pipe communicates with the groove formed in the solution collecting member. An actuator is provided to move a blocking member between an open position and closed position to open and close the groove.
