This thesis implemented security systems of voice awareness which is higher accessible than existing security system using biological authentication system and is inexpensive in module of security device, and has an advantage in usability. Proposed the security systems of voice awareness implemented algorithm for characteristic extraction of inputted speaker's voice signal verification, and also implemented database of access control that is founded on extractible output. And a security system of voice awareness has a function of an authority of access control to system.

가연성 가스가 누출함에 따른 화재 및 폭발 재해는 공업화 사회에 있어서 방치될 수 없는 매우 중요한 문제이다. 기체, 액체, 분체가 단면적이 작은 분출구를 통해 공기중으로 분출될 때 분출하는 물질과 분출구와의 마찰로 인해 정전기가 발생한다. 분출되는 물질과 분출구를 구성하는 물질의 직접적인 마찰에 의해서도 정전기가 발생하고, 분출되는 물질 구성입자들간 상호충돌에 의해서도 정전기가 발생된다. 배관 내에 순수천연가스가 이송ㆍ분출할 때의 대전량은 매우 작다. (중략)

The proposed high-speed backup and recovery system is a high performance backup software based on multi streaming I/O and high speed/high compression technology, and can realize an increase efficiency of backup volume without any increase of backup H/W equipments since it provides a high performance in data backup of a user and executes high compression very fast. Particularly, it minimizes consumption of network band width through a development of algorism for high compression in connection with backup equipments in a large-scaled system environment, is automated when it is recovered due to danger and troubles, and allows users to conveniently access in various ways since GUI and CLI for execution and management are all provided.
