A tool for surgical operation using ultrasonic waves is provided. The tool includes a transducer generating ultrasonic waves, a cylindrical bar-shaped transmitting rod for transmitting the ultrasonic waves, an end effector for cutting a surgical site using the ultrasonic waves transmitted from the transmitting rod, extended from one end of the transmitting rod, in which a part of the circular cross-sectional area thereof is flatly formed from the point corresponding to a second vibration node so as to allow gain step to start at the second vibration node, a rod cover for encompassing the transmitting rod using, as connection points, a plurality of vibration nodes formed when ultrasonic waves are transmitted through the transmitting rod, and a jaw for holding the surgical site while engaged with the end effector, is combined to one end of the rod cover in a pivotable manner, and is positioned to face the end effector.

Disclosed is a method of producing 2,3-butanediol using a recombinant yeast having a 2,3-butanediol biosynthesis pathway controlled in a metabolic engineering manner. The method enables production of 2,3-butanediol at high production efficiency from glucose or xylose using a recombinant yeast wherein enzymatic activity of pyruvate decarboxylase is inhibited and exotic genes associated with 2,3-butanediol biosynthesis are introduced.

A method for using contents, a method for sharing contents, and a device based on security level are disclosed. A method for using contents based on security level creates a device security level according to the number of device identification elements, receives contents, and if the device security level is found to be a minimum allowed device security level for using the contents, uses the contents. Therefore, a device that does not satisfy the conditions required for using contents cannot use the contents, whereby security is reinforced.

Method for protecting contents, method for sharing contents and device based on security level

The present invention relates to a method of managing a domain employing a multi-domain manager and a domain system. The method of managing a domain employing a multi-domain manager includes designating a primary domain manager, configuring the domain by registering a domain device with the primary domain manager, designating at least one secondary domain manager of the domain devices, and managing the domain through conjunction of the primary domain manager and the secondary domain manager. Thus, domain management can be performed efficiently by employing a multi-domain manager.

Method for managing domain using multi domain manager and domain system

A method and system for secure communication is provided. The method for secure communication with devices includes: obtaining a parameter for protecting a content; authenticating each other by exchanging a certificate with the device; and exchanging a key with the device using a key authenticated through the certificate to establish a secure authenticated channel with the device. Accordingly, it is possible to establish the secure authenticated channel and perform secure communication by computing a secure authenticated channel key.
