Abstract:
The present invention relates to a method and apparatus for protecting data using a virtual environment, which creates a safe virtual environment that supports the execution of application programs being operated on a computer and which enables important data to be inputted or outputted only within the virtual environment, such that access to the important data is prevented in a general local environment. According to the present invention, data leakage is initially prevented to protect data, and convenience is provided in that a user may use the computer in a general manner while performing desired work.
Abstract:
The present invention relates to a cardiovascular diagnostic system which enables early detection of cardiovascular diseases and defines their causes. Unlike known electrocardiographs, the cardiovascular diagnosis system can further measure elastic coefficient of blood vessels (the degree of arteriosclerosis), blood vessel compliance, blood flow, and blood flow resistance and velocity in blood vessel branches of the right and left coronary arteries. The elastic coefficient shows organic changes to blood vessels. The compliance shows organic and functional changes of blood vessels simultaneously. The blood flow shows blood flow resistance.
Abstract:
A system for logically separating a server using client virtualization includes a client terminal including a virtual environment generation unit for generating a virtual environment, and a virtualized server including a local storage unit, an authentication server for performing authentication on the client terminal when a request for access to the local storage unit is received from a process executed in the virtual environment, and a virtualization filter drier for allowing or blocking the access request to the local storage unit based on the authentication result of the client terminal. The client terminal further includes a virtualization filter driver for transmitting the access request from the process executed in the virtual environment to the local storage unit, and blocking the access request from the process without being made through the virtual environment to the local storage unit.
Abstract:
The present invention relates to a cerebrovascular analysis system which enables early diagnosis of various incurable cerebrovascular diseases such as cerebral thrombosis by measuring an elastic coefficient, blood vessel compliance, blood flow resistance, and blood flow in each cerebrovascular branch. The measurement is achieved by biomechanically analyzing blood vessels in the brain using an electrocardiogram, phonocardiogram, electroencephalogram, pulse wave, and ultrasonic doppler signal as basic data in order to measure biomechanical properties and blood flow properties of blood vessels in the brain for the diagnosis of cerebrovascular diseases.
