An information protection system includes a mobile terminal and an encryption module. The mobile terminal requests a key sequence by transmitting a message including a Personal Identification Number (PIN) number input by a user, and encrypts or decrypts one or more communication signals, including voice signals and data signals, based on the key sequence when the key sequence is received. The encryption module is connected to the mobile terminal. The encryption module encrypts a security key using the identifier and the PIN number of the mobile terminal, decrypts the encrypted security when requested by the mobile terminal, and transmits the key sequence generated based on the decrypted security key to the mobile terminal.

A system and a method for preventing drowsiness are provided. The system for preventing drowsiness calculates brainwaves of a user by receiving a signal around a head of a user without contact, detects a state of the user based on the calculated brainwaves, and performs a necessary function according to the detected state of the user. Thus, convenience is increased when measuring the brainwaves of the driver using the contactless electrodes.

The present invention relates to a biochip for detecting phosphorylation and a method for detecting phosphorylation using the same, more precisely a biochip prepared by integrating a protein produced from the recombination of a substrate of kinase selected from the group consisting of PKC (Protein Kinase C), cdc2-PK (cdc2 Protein Kinase) and DNA-PK (DNA-dependent Protein Kinase) and the elevated protein such as Selenomonas ruminantium membrane protein on a matrix surface coated with an active group, a kit for detecting phosphorylation composed of the said biochip and a cofactor labeled with a radio-isotope and a method for detecting phosphorylation using the same. The biochip for detecting phosphorylation of the present invention using a radio-isotope facilitates the detection of phosphorylation with a minimum amount of a sample by simple processes, compared with the conventional method using an antibody. Since this method can analyze a large amount of samples in a shorter period of time, it can be effectively used for the analysis of kinase activity.

The present invention relates to a plastic substrate having a multi-layer structure and a method for preparing the same. The plastic substrate of the present invention comprises plastic films attached to each other, and a first buffering layer of an organic-inorganic hybrid, a layer of gas barrier, and a second buffering layer of an organic-inorganic hybrid which are stacked on both sides of the plastic films in an orderly manner, each layer forming a symmetrical arrangement centering around the plastic films. Because the plastic substrate of the present invention has a small coefficient of thermal expansion, excellent dimensional stability, and superior gas barrier properties, it can replace the brittle and heavy glass substrate in display devices. Also, it can be used for a variety of packaging or container materials in applications requiring superior gas barrier properties.
