20080307006 | FILE MUTATION METHOD AND SYSTEM USING FILE SECTION INFORMATION AND MUTATION RULES - Provided are a file mutation method and a system using file section information and mutation rules. The file mutation system includes: a file section information extraction module obtaining file section information with respect to a sample file of a known file format; a file section information production module producing file section information with respect to a sample file of an unknown format; a mutation rule production module receiving a user input that a mutation rule is applied and producing a mutation rule, the mutation rule defining a mutation function that is to be applied to each data type; and a file mutation module receiving the sample file and producing a plurality of test case files that are created by mutating the sample file through the file section information processed in the file section information extraction module and the file section information production module and the mutation rule from the mutation rule production module. | 12-11-2008 |
20080313417 | APPARATUS AND METHOD OF DETECTING AND CONTROLLING PRIVILEGE LEVEL VIOLATION PROCESS - Provided are an apparatus and method of detecting and controlling a privilege level violation process. The apparatus monitors whether higher-privileged processes depend on information provided from lower-privileged objects or denies the higher-privileged processes to access the lower-privileged objects. The apparatus is provided in a process, and monitors whether a process accesses to a lower-privileged object. The apparatus gives a warning message or denies an access of the process to the lower-privileged object when it detects that the higher-privileged process access to the lower-privileged object. Therefore, the apparatus of detecting and controlling a privilege level violation process detects weaknesses that may be caused by privilege level violation, thus allowing a system to be safely operated. | 12-18-2008 |
20090100517 | APPARATUS AND METHOD FOR MONITORING AND PROTECTING SYSTEM RESOURCES FROM WEB BROWSER - An apparatus and method for preventing an attempt to perform malicious activities using web browser weaknesses are provided. A file protection module monitors attempts to access at least one file resource when the web browser executes a program, and allows or denies access. A registry protection module monitors attempts to access at least one registry resource when the web browser executes a program, and allows or denies access. A process protection module monitors attempts to execute or terminate at least one process when the web browser executes a program, and allows or denies the execution or termination. | 04-16-2009 |
20100227370 | METHOD OF PRODUCING LYCOPENE USING RECOMBINANT ESHERICHIA COLI - A method of producing lycopene, with high productivity by means of a recombinant bacterial strain includes preparing the recombinant vector containing genes encoding proteins, which are required for lycopene biosynthesis. The genes involved in lycopene biosynthesis are crtE, crtB and crtI, and at least one of the said three genes (crtE, crtB and crtI) is selected from the group consisting of crtE with the nucleotide Sequence 1, crtB with the nucleotide Sequence 3 and crtI with the nucleotide Sequence 5, of the Sequence List. The said recombinant vector is transformed into | 09-09-2010 |
20110124090 | GENE INVOLVED IN THE BIOSYNTHESES OF LYCOPENE, RECOMBINANT VECTOR COMPRISING THE GENE, AND TRANSFORMED MICROORGANISM WITH THE RECOMBINANT VECTOR - There are provided genes involved in the biosynthesis of lycopene and having DNA sequences set forth in SEQ ID NO: 1, SEQ ID NO: 3 and SEQ ID NO: 5 encoding proteins required for the biosynthesis of lycopene, a recombinant vector comprising at least one of the genes, and a mi | 05-26-2011 |
20110219454 | METHODS OF IDENTIFYING ACTIVEX CONTROL DISTRIBUTION SITE, DETECTING SECURITY VULNERABILITY IN ACTIVEX CONTROL AND IMMUNIZING THE SAME - Provided is a method of identifying an ActiveX control distribution site, detecting a security vulnerability in an ActiveX control and immunizing the same. A security vulnerability existing in an ActiveX control may be automatically detected, effects brought on by the corresponding security vulnerability may be measured, and abuse of the detected security vulnerability in a user PC to be protected may be immediately prevented. Therefore, since the user PC may be protected regardless of a security patch, it is anticipated that security problems in the Internet environment caused by imprudent use of the ActiveX control may be significantly enhanced. | 09-08-2011 |

20140186181 | SHIP PROPULSION DEVICE AND SHIP HAVING THE SAME - Disclosed are a ship propulsion device and a ship having the same. According to one embodiment of the present invention, the ship propulsion device includes a rear propeller fixed on a drive shaft; a front propeller supported on a drive shaft of the front of the rear propeller to be rotated; and a reverse rotary device having a plurality of gears which are provided on a rear side of the ship, and transmits rotation of the drive shaft after reversing the rotation to the front propeller. | 07-03-2014 |
20140206899 | METHOD FOR PURIFYING SULFONATED AROMATIC MONOMER - The present invention relates to an improved method for purifying a sulfonated aromatic monomer. The method is an economical method capable of providing a highly pure sulfonated aromatic monomer, in which a salt precipitation step and a recrystallization step are simplified while maintaining the reaction conditions used in a conventional method for synthesizing the sulfonated aromatic monomer, and a purification process is carried out using an easily available and stable chemical substance. The sulfonated aromatic monomer obtained by the purification method will be useful for the preparation of a polymer for a polymer electrolyte membrane and will be advantageous to synthesize polymer with high molecular weight. | 07-24-2014 |
