摘要:
Provided is a system and method for providing dangerous road information based on a Ubiquitous Sensor Network (USN) in real-time. The system includes: a dangerous road zone information sensing unit having a sensing function for sensing diverse information in a dangerous road zone and a computing function for extracting dangerous road information by analyzing the sensed information; a dangerous road zone information transmitting unit for transmitting the extracted dangerous road information through a short distance wireless network; a dangerous road zone information collecting unit for collecting the transmitted dangerous road information and checking duplication elimination and unification of the dangerous road information; and a dangerous road zone information providing unit for providing the dangerous road information collected and processed in the dangerous road zone information collecting unit to a Telematics vehicle approaching to the dangerous road zone in real-time through wireless communication.

An apparatus and method of preventing a collision of vehicle in a crossroad are disclosed. The apparatus includes: an information generating unit installed at each of roads near the crossroad for generating real-time vehicle information by integrating vehicle's information including a speed and a position provided from the vehicles on each of the roads and traffic sign information; and an information collecting and providing unit for providing the traffic sign information to the information generating unit, collecting vehicles' information in real-time from the information providing means of a predetermined road near the crossroad, storing the collected information, and providing the collected information to vehicles approaching the crossroad through another roads for the vehicles to predict a collision in the crossroad.

A method for storing database information includes storing a table having data values in a column major order. The data values are stored in a list of blocks. The method also includes assigning a tuple sequence number (TSN) to each data value in each column of the table according to a sequence order in the table. The data values that correspond to each other across a plurality of columns of the table have equivalent TSNs. The method also includes assigning each data value to a partition based on a representation of the data value. The method also includes assigning a tuple map value to each data value. The tuple map value identifies the partition in which each data value is located.

Disclosed are an epitope specific to hepatitis B virus (HBV) and use thereof. The disclosed epitope is a conservative position on which mutagenesis does not occur and, therefore, a composition including an antibody to the foregoing epitope or a vaccine composition including the epitope has very low possibility of causing degradation of curing efficacy due to HBV mutation, thus being very useful for HBV treatment.
