Abstract: A superconducting arcing induction type DC circuit breaker includes a superconducting fault current limiter and an arcing induction type DC circuit breaker connected in series to each other. The arcing induction type DC circuit breaker includes an induction member that has a through-hole, is continuously formed in a 360-degree direction, and has a certain shape and thickness, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member. A contact point where an anode and a cathode, which are mechanical contacts, approach from opposite directions and come into contact with each other is formed in the through-hole of the induction member, and the anode and the cathode are separated in a direction far away from each other.

Abstract: Provided is a user authentication system and method for supporting terminal mobility between user lines. The user authentication system includes: a binding checker that checks whether a user terminal ID and a circuit ID of a line currently connected to the user terminal are bound; a terminal/circuit information checker that checks whether the user terminal ID and the circuit ID are validly registered for a network service if the check result obtained by the binding checker shows that binding is not made; and a terminal authenticator that authenticates the user terminal by temporarily binding the user terminal ID and the circuit ID if the terminal/circuit information checker confirms validity of the registration. Accordingly, a pre-authenticated user terminal can receive a network service by accessing another user line. Therefore, it is possible to create various business models in which a service and a service fee system are determined according to an end user's SLA.

Abstract: Provided are an apparatus and method for modeling and analyzing a network simulation for a scalable simulation framework (SSF)-based network simulation package. A system logic set is generated and a network simulation modeling suitable for a predetermined network application is formed according to the system logic set. The network simulation modeling is transmitted to a predetermined network simulation package that performs simulation. Statistical information is generated based on the result according to the system logic set. Complicated network simulation modeling errors can be minimized, and remodeling of the network simulation modeling can be reduced.

Abstract: A method of preventing contaminating particles in a chamber in a deposition device is presented. In the method, a substrate is mounted within a chamber of gas-exposure equipment. The pressure within the chamber is reduced and a treatment gas is injected into the chamber to convert a surface of the substrate to be organic. After a desired time is elapsed, the pressure within the chamber is allowed increase to atmospheric pressure or above by introducing nitrogen gas into the chamber. Nitrogen gas introduction prevents entry of air, including the moisture within the air. Without the moisture, contaminating particles are not generated since the moisture is prevented from reacting with an ammonia component of the treatment gas.
