Abstract: The present invention relates to an antimicrobial adjuvant containing a biphenyl derivative compound as an active ingredient, and a technology of various uses thereof. The compound of the present invention reduces the dosage of polymyxin antibiotics, which are administered to inhibit the proliferation of gram-negative bacteria, by enhancing the sensitivity of the gram-negative bacteria with respect to the polymyxin antibiotics, is concomitantly administered with the polymyxin antibiotics to show gram-negative bacteria growth inhibitory and killing effects, may notably reduce side effects such as nephrotoxicity, and may prevent or treat sepsis and septic shock due to antibiotic overuse.

Abstract: Disclosed are an ampoule-fixing holder for an intraosseous anesthetic solution injection device and an anesthetic solution injection device including the same. The ampoule-fixing holder includes a cylindrical holder body including an open portion formed at the rear end thereof to allow an ampoule containing an anesthetic solution to be inserted thereinto or removed therefrom, a head configured to enable mounting of an injection needle to the front end of the holder body, a rotary body disposed between the head and the holder body to withstand rotational force and an axial load, and a fixing member configured to firmly hold the ampoule inserted into the holder body to effectively transmit rotational force to the ampoule.

Abstract: A method for configuring an observable object as a digital twin in a digital twin system of any one domain is provided. The method for configuring a digital twin includes defining a purpose for expressing the observable as a digital twin in the domain, organizing data based on a role of the observable object in the domain, configuring the observable object into the digital twin based on the data for the purpose, and synchronizing the observable object and the digital twin.

Abstract: The present invention relates to a method of defending against a spoofing attack using a blocking server, and more particularly, to a method of defending against a spoofing attack using a blocking server, which is characterized in that it involves inspecting an IP and MAC address included in an ARP packet received by a client in a network, and changing the addresses to a legitimate IP address and to a corresponding MAC address when the addresses are found to be used in a spoofing attack. According to the present invention, in the blocking of a spoofing attack against a network, an IP address and a MAC address for legitimate hardware connected to the network may be prestored and monitored, so as to exhibit the effect of an accurate defense being enabled in a short time.

Abstract: The present invention relates to a malicious code blocking method using a management system for monitoring a state of a vaccine, and more specifically, to a malicious code blocking method using a management system for monitoring a state of a vaccine, in which the management system connected through the Internet monitors in real-time whether or not a vaccine program installed in an individual user terminal normally operates and transmits an alarm to a user when the vaccine program does not operate normally, thereby removing a malicious code. According to the present invention, because an error or a paralyzed state of a vaccine program which cannot be easily understood by general users is informed in real-time, the vaccine program can be promptly normalized regardless of the knowledge and interest of a user, and thus it is effective in that infection and additional damage of the malicious code can be prevented.

Abstract: The present invention relates to a system and method for analyzing a repackaged application through risk calculation, and more specifically, to a system and method for analyzing a repackaged application through risk calculation, which confirms existence of a malicious code by scoring whether or not an application installed in an Android smart phone is repackaged. According to the present invention, malicious applications classified as a repackaged mutant may be extensively detected.

Abstract: The present invention relates to a method and system for automatically verifying a computer vaccine database and, more particularly, to a method and system for automatically verifying a computer vaccine database, which is capable of automatically verifying and modifying a vaccine database mounted on a vaccine engine so that a normal program is not recognized as viruses or malicious codes by storing information about the normal program in the vaccine database in order to remove computer viruses or malicious codes. According to the present invention, a file set of the latest vaccine database can be rapidly collected and processed, and the problems of a vaccine database file provided by a vendor can be checked in advance. Accordingly, there are advantages in that a function of alarming error conditions and a process of reporting error in a vaccine database update process can be automated.
