摘要:
The present invention relates to a method of controlling access to a wireless channel in a wireless communication system, and more particularly, to such a method of controlling wireless channel access, in which it is determined whether or not peripheral communication nodes are ones interrupting main communication between communication nodes being activated, and if it is determined that the peripheral communication nodes are ones which does not interrupt the main communication, they gain access to a wireless channel so as to perform parallel communication with respect to the main communication. The wireless channel access control method according to the present invention determines whether or not peripheral communication nodes actually interrupt main communication, and if it is determined that the peripheral communication nodes are ones which does not interrupt the main communication, they gain access to a wireless channel so as to perform parallel communication with respect to the main communication, thereby efficiently utilizing a limited wireless channel resource.

Provided is a surface showing excellent antithrombotic properties. Also provided is a medical device having the same. An antithrombotic surface comprising polymer layers which are in different charged states and alternately layered, characterized by having three-dimensional peaks and valleys formed thereon. The antithrombotic surface as described above which is further characterized in that the peaks and valleys are 15 nm or more but not more than 200 nm in height and depth respectively. A medical device characterized by being provided with the antithrombotic surface as described above. Thus, a thin and highly antithrombotic surface or medical device can be obtained by a relatively convenient method.

A method is provided for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, in which an MN that has moved from a source Personal Area Network (PAN) to a target PAN, sends a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN, and receives a Router Advertisement (RA) message from the gateway in response to the RS message. The RA message includes a home prefix of the MN as the requested profile. The method supports mobility of MNs, enables unicast communication, and facilitates efficient use of the network.

A liquid crystal display device includes an array substrate having reflective and transmissive regions in a pixel region, wherein the array substrate includes a reflective electrode corresponding to the reflective region and a pixel electrode on a first substrate. A color filter substrate defines the reflective region and the transmissive region in the pixel region. The color filter substrate includes a color filter with first and second portions that correspond to the respective transmissive and reflective regions on a second substrate. The thickness of the second portion is less than a thickness of the first portion. The combined thickness of the scatter and the thickness of the second portion is greater than the thickness of the first portion; and a liquid crystal layer between the array and color filter substrates.

A vertical NAND flash memory device includes a substrate having a face and a string of serially connected flash memory cells on the substrate. A first flash memory cell is adjacent the face, and a last flash memory cell is remote from the face. The flash memory cells include repeating layer patterns that are stacked on the face, and a pillar that extends through the series of repeating layer patterns. The pillar includes at least one oblique wall. At least two of the series of repeating layer patterns in the string are of different thicknesses. Other vertical microelectronic devices and related fabrication methods are also described.

摘要:
System and method provide an on-line high-performance diagnosis service for cardiovascular disorders. A client requests a high-performance diagnosis by transmitting real electrocardiographic treatment data and magnetocardiographic treatment data of a human body being a treatment object and virtual heart simulation parameters to a medical service server. The medical service server, in response to the diagnosis request, analyzes the real electrocardiographic treatment data to generate an electrocardiographic analysis result, and performs a virtual heart simulation using the simulation parameters to generate a pseudo electrocardiogram and magnetocardiogram. Further, the medical service server determines a disease state of the human body on the basis of the electrocardiographic analysis result, the magnetocardiographic treatment data and the pseudo electrocardiogram and magnetocardiogram, and generates definitive diagnosis data through comparison among the real magnetocardiographic treatment data, the electrocardiographic analysis result, the disease state, and a diagnosis criteria. The definitive diagnosis data is provided to the client.
