Abstract: Disclosed are a method and apparatus for reusing wastewater. The method for reusing wastewater disclosed herein includes: generating a mixed wastewater by mixing multiple types of wastewater (S20); performing a first purification by passing the mixed wastewater through a flocculation-sedimentation unit (S40); performing a second purification by passing an effluent of the flocculation-sedimentation unit through a membrane bioreactor (MBR) (S60); performing a third purification by passing an effluent of the MBR through a reverse-osmosis membrane unit (S80); and reusing an effluent of the reverse-osmosis membrane unit as cooling water or industrial water (S100).

Abstract: Disclosed is a high voltage output device having a serial-parallel stack structure of capacitors. The high voltage output device includes a substrate includes a capacitor element and a pillar structure provided on an upper surface of the substrate. The substrate includes a first electrode and a second electrode, which have different potentials from each other. The capacitor element is connected to at least one of the first electrode and the second electrode.

Abstract: A system and method by which an unnecessary General Packet Radio Service (GPRS) attach procedure is no longer performed when a service cancellation situation is generated during execution of a GPRS attach procedure according to a data service requested by a user is provided. The system determines whether an abnormal situation occurs in an Europe-oriented General Packet Radio Service/Universal Mobile Telecommunication System (GPRS/UMTS) mobile terminal and immediately terminates a currently proceeding attach procedure when an abnormal service cancellation situation occurs. The abnormal situation occurs when the user cancels a service during use of a data service (e.g., Wireless Application Protocol (WAP), Multimedia Message Service (MMS)) or when connection of the service fails due to a bad network state.

Abstract: A function by which an unnecessary General Packet Radio Service (GPRS) attach procedure is no longer performed when a service cancellation situation is generated during execution of a GPRS attach procedure according to a data service requested by a user is implemented. To do this, a system is configured to determine whether an abnormal situation occurs in an Europe-oriented General Packet Radio Service/Universal Mobile Telecommunication System (GPRS/UMTS) mobile terminal and to immediately terminate a currently proceeding attach procedure when an abnormal service cancellation situation occurs. Herein, the abnormal situation can occur when the user cancels a service during use of a data service (e.g., Wireless Application Protocol (WAP), Multimedia Message Service (MMS)) or when connection of the service fails due to a bad network state.

Abstract: An inter system handovers in a mobile telecommunication system is performed when a dual mode user equipment (UE) covered by both GSM/GPRS network and UMTS network connects a dedicated channel and sets up a call in a BSS region where the GSM/GPRS provides coverage, and then moves to a UTRAN (UMTS Terrestrial Radio Access Network) where the UMTS provides coverage, wherein the method includes the steps of: if the dual mode UE receives an inter system handover command, i.e.
