摘要:
An ultrasonic diagnostic apparatus is disclosed. The ultrasonic diagnostic apparatus includes a housing exposing one side of a diagnosis target while supporting the diagnosis target so as to maintain a shape of the diagnosis target, an oblique part obliquely formed on the housing to support the diagnosis target, and a probe unit disposed inside the housing to examine the diagnosis target. The ultrasonic diagnostic apparatus ensures efficient diagnosis of the overall diagnosis target without excessive compression of the diagnosis target causing examinee discomfort, and can support the diagnosis target so as to maintain the shape of the diagnosis target, thereby ensuring the provision of a constant quality of ultrasonic images upon repetitious diagnosis of the diagnosis target while improving reproducibility of diagnosis results.

摘要:
A method for detecting an error of system information in a mobile communication system is disclosed. A radio resource control (RRC) packet data unit (PDU) is created to transmit system information and the length of the RRC PDU is checked to determine if an error exists, with the RRC PDU sent to user equipment through a primary common control physical channel (PCCPCH) if no error exists.
