摘要： In a system and method for providing Push To Talk (PTT) service according to a state of the user, when a PTT terminal user is absent, in conference or busy, the PTT system converts the PTT voice message directed to the PTT terminal to a text message, and displays it on a screen of another terminal or the PTT terminal. As a result, the user can immediately check the PTT message when he/she is in absence or conference state, and is busy without communication interference.

摘要： Organometal-containing acrylate or methacrylate derivatives and photoresists comprising the polymers thereof. Unlike conventional matrix polymers of photoresist, the polymers induce a difference in silicon content between exposed regions and unexposed regions of photoresists by releasing their silicon-containing side chains with the aid of acid in a chemical amplification manner. The difference in silicon content causes the exposed regions to be etched at a different rate from that of the unexposed regions under oxygen plasma. Thus, the photoresist material makes it possible to use a microlithographic process comprising a dry development step which can advantageously prevent the deformation or collapse of patterns which is aggravated as their aspect ratio increases, as well as the photoresist is economically more favorable than a top surface imaging system to which silylation on its top surface or a multi-level resist system to which wet development on its top layer must be applied, because the microlithographic process is very simple and no solvent is released.
