Title: Software floating license management method using network and system thereof
Inventor: CHOI JEONG UK
IPC: G06F17/00
Filed: 2002-11-20
Abstract: PURPOSE: A floating license management method and system is provided to make a license manager of a server manage a license issue, a license termination request or a current status of a client, and to determine whether a client has a legal effective license. CONSTITUTION: The method comprises several steps. An application at a client is executed(s200). A license process module at the client transmits a license allotment request signal to a license manager at a server(s202). If the license module at the client receives a license certification signal from the license manager at the server(s204), the license module at the client normally drives the application, and executes a timer for a repetitive request of a license(s206). The license module transmits a repetitive request of the license to the license manager at every set time set in the timer, and receives permission or no-permission signals for the requests. According to the received signals, the application is continuously driven or stopped.

Abstract: PURPOSE: A method for preparing racemic indene oxide using MnSO4 catalyst is provided, thereby simplifying the preparation process, reducing the cost for preparation, and improving the preparation yield. CONSTITUTION: The method for preparing racemic indene oxide using MnSO4 catalyst comprises the steps of: adding indene and MnSO4 catalyst into solvent at room temperature; and slowly adding droplets of oxidizing agent containing solution into the indene solution at a constant reaction temperature to epoxidation of indene, wherein the solvent is N,N-dimethylformamide, acetonitrile and acetone; and oxidizing agent is hydrogen peroxide.
