Abstract: Provided is a defect analysis device which may include a light source that irradiates an analysis target layer of an element with light, a position adjuster that adjusts a position in the analysis target in the analysis target to be irradiated with the light, a detector that measures a current value of current flowing between a source area of the element electrically connected to one end of the analysis target layer and a drain area of the element electrically connected to the other end of the analysis target layer in the element, and an analyzer that acquires quantitative data related to a defect in the analysis target layer on the basis of the current value in which, in a first mode, a plurality of areas of the analysis target layer are sequentially irradiated with the light.

Abstract: A computer program product, apparatus and method for establishing a voice call of a mobile communication system includes: authenticating an origination terminal through a traffic channel by performing call connection between the origination terminal and an origination side network; authenticating a destination terminal through a traffic channel by performing call connection between a termination side network and the destination terminal when the authentication is successful; and establishing a speech path between the origination terminal and the destination terminal when the destination terminal is successfully authenticated. A request and submission of an OTP for authenticating a user of a mobile terminal is possibly performed according to the voice call protocol, whereby the security of the mobile terminal can be strengthened and the strong demand of users with respect to protecting the privacy and information can be satisfied.

Abstract: A method for enhancing a voice call reception rate in a mobile communication terminal is provided. Voice call reception is enhanced by selectively limiting idle handoff generation by setting idle handoff occurrence conditions to be more difficult if an idle handoff from the first base station to the second base station accompanies a packet zone reconnection procedure and/or by performing the packet zone reconnection only when the mobile communication terminal remains in a zone of the second base station for a predetermined time if the handoff between the first base station and the second base station is necessary.
