In a display apparatus, a light guide plate includes a chamfered corner portion that defines a light incident surface. A light source unit is arranged adjacent to the light incident surface to provide the light to the light guide plate through the light incident surface. A display panel receives light from the light guide plate to display an image. A receiving container includes sidewalls and a bottom portion to accommodate the light guide plate and the light source unit. At least one sidewall adjacent to the corner portion is divided into a first part and a second part that may be coupled to or separated from each other. Thus, the light guide plate and the light source unit may be easily accommodated in the receiving container, thereby improving an assembling efficiency.

Disclosed are example bipolar transistors capable of reducing the area of a collector, reducing the distance between a base and a collector, and/or reducing the number of ion implantation processes. A bipolar transistor may includes a trench formed by etching a portion of a semiconductor substrate. A first collector may be formed on the inner wall of the trench. A second collector may be formed inside the semiconductor substrate in the inner wall of the trench. A first isolation film may be formed on the sidewall of the first collector. An intrinsic base may be connected to the third collector. An extrinsic base may be formed on the intrinsic base and inside the first isolation film. A second isolation film may be formed on the inner wall of the extrinsic base. An emitter may be formed by burying a conductive material inside the second isolation film.

The present invention relates to a recording medium a method and an apparatus for generating virtual teeth and recording media storing a program performing the method. According to an embodiment of the present invention, a method for generating virtual teeth includes (a) acquiring a tooth image having three-dimensional information from teeth including a damaged tooth; (b) determining an image of a virtual tooth to be inserted into a position of the damaged tooth in a tooth image library having predetermined three-dimensional information and inserting the determined virtual tooth image into the acquired tooth image; and (c) modifying the virtual tooth image by considering tooth images positioned at upper and lower sides or right and left sides of the virtual tooth image. According to the embodiment of the present invention, it is possible to produce a prosthesis most suitable for the state of patient's teeth only once and an operator can minimize post-processing of the produced prosthesis. Further, a patient can minimize a clinic time and decrease the number of times of hospital visits.

There is provided a method and system for detecting and responding to harmful traffic. The system includes a router determining whether or not received data is harmful traffic, by using a dynamic flow identification (DFI) function and a deep packet inspection (DPI) function, sending Cflowd information of the received data, and then encapsulating the received data when the received data is determined to be harmful traffic, a policy & resource control entity receiving the Cflowd information from the router, determining whether or not the received data is harmful traffic by using the received Cflowd information, and then sending a result of the determination to the router, and a security management server receiving the encapsulated data from the router, reconfirming whether or not the encapsulated data is harmful traffic, and then processing the encapsulated data.
