Provided is a method for finding a minimal signed digit with variable multi-bit coding. The method includes the steps of: scanning and grouping given multi-bit and checking the type of each group; deciding whether each group is to be performed by any one of a coding for positive number and a coding of negative number depending on the type of each group; converting the value of each group into a corresponding value of different number system and finding a signed digit based on the converted value; if the type of each group indicates the coding for negative number, performing bitwise inverting on the value of each group; and converting multi-bit subjected to the bitwise inverting into a corresponding value of different number system, and finding a signed digit based on the converted value.

The present invention relates to a method and an architecture capable of efficiently providing a virtual desktop service. The service architecture for the virtual desktop service includes a connection broker for performing the management of virtual machines, a server monitoring function, and a protocol coordination function. A resource pool is configured to manage software resources that are transferred to a specific virtual machine in a streaming form at a predetermined time and that are executed on the specific virtual machine and to provide provision information about the managed software resources at the request of the connection broker, in order to provide an on-demand virtual desktop service. A virtual machine infrastructure is configured to support hardware resources, generate virtual machines in which the software of the user terminal is operated, and provide the virtual machines as virtual desktops.

Disclosed herein are a virtual server and a virtual machine management method for supporting a zero client. The virtual server includes a virtual machine management agent unit and a virtualization unit. The virtual machine management agent unit generates a virtual host interface resource pool and a directly allocatable host interface resource pool by classifying attributes of host interface resources of the virtual server. The virtualization unit provides a host interface of a virtual machine by selectively using any one of emulation mode in which a virtual host interface set corresponding to the virtual host interface resource pool is generated and direct connection mode in which a directly allocatable host interface set corresponding to the directly allocatable host interface resource pool is connected to the zero client.

Provided are a method, client and system for reservation access to a management server using a one-time password. A generated personal identification number (PIN) is transmitted to the management server when a reservation time comes. The management server generates a random number encrypted using the PIN and transmits the random number to the client. The random number encrypted using the PIN is received, the received random number is encrypted by a symmetric-key algorithm using a client secret key and is transmitted to the management server. The management server receives the random number encrypted using the client secret key, and decrypts the received random number using a server secret key and the PIN. A random number before the encryption using the PIN is compared with a decrypted random number, and access of the client is accepted if the two numbers are identical. Automatic access to a system employing a one-time password authentication method can be made through an arbitrary route according to previously reserved settings to perform information collection and to process specific functions in the case where a system manager is unable to directly access the system through a determined route because of temporal and spatial limitations.

According to example embodiments, there is provided a semiconductor device including a substrate and an isolation layer structure. The substrate includes an active region having an upper active pattern and a lower active pattern on the upper active pattern. The active region has a first aspect ratio larger than about 13:1 and a second aspect ratio smaller than about 13:1. The first aspect ratio is defined as a ratio of a sum of heights of the upper active pattern and the lower active pattern with respect to a width of the upper active pattern. The second aspect ratio is defined as a ratio of the sum of the heights of the upper active pattern and the lower active pattern with respect to a width of the lower active pattern. The isolation layer structure is adjacent to the active region.
