Abstract: The present invention relates to a pyrrolobenzodiazepine derivative compound, a conjugate of the same with a ligand, and the use of the same. The pyrrolobenzodiazepine derivative compound is more stable in plasma, is stable even in circulation, and exhibits excellent efficacy. In particular, the conjugate of the pyrrolobenzodiazepine derivative compound with a ligand has a great advantage in that it is possible to target and specifically treat proliferative disease such as cancer, maximize drug efficacy, and minimize the expression of side effects since the conjugate more stably reaches the target cell and effectively exerts drug efficacy while toxicity is greatly reduced as a linker technology that allows drugs to be easily released within cancer cells and maximize drug efficacy is incorporated.

Abstract: The present invention discloses a network connection managing system comprising one or more information devices, a network node data verifying device and a network node connection managing device. The information device is a network node installed with a mobile network card such that a MAC address of the mobile network card and network node identifying data of the network node are transmitted to the network node data verification device by a data reporting software, and are then compared by the network node data verifying device. The network node connection managing device is connected to the network node data verifying device and blocks a network connection for the network node according to a comparison result.

Abstract: Disclosed is an IPv6 network node managing method, comprising: a packet collecting step, a packet analyzing step, and an IPv6 address assigning step, for assigning a network node management IPv6 address with a visually recognizable suffix address code to a target network node which requests an IPv6 address assignment of DHCPv6, thereby improving IPv6 address recognition of the target network node and facilitating management of the network nodes.

Abstract: The present invention relates to a novel pyrrolobenzodiazepine dimer compound or a pharmaceutically acceptable salt thereof, a ligand-drug conjugate compound thereof, or a composition containing the same and therapeutic use of the same as an anticancer agent. The pyrrolobenzodiazepine dimer compound according to the present invention exhibits anticancer activity equivalent to or superior to that of existing anticancer agents when being applied to a ligand-drug conjugate as a drug and administered as well as exhibits low activity and greatly diminished toxicity in the free toxin form and thus has a significantly improved therapeutic index. Hence, the pyrrolobenzodiazepine dimer compound is highly industrially applicable in that targeting of proliferative diseases such as cancer is possible, specific treatment of the proliferative diseases is possible, the drug efficacy can be maximized, and the expression of side effects can be minimized.

Abstract: The invention provides a method for distinguishing and blocking off a network node. The method includes a packet receiving step and a packet distinguishing processing step. The packet receiving step is provided for receiving an ARP packet from a network node within a network segment. The packet distinguishing processing step is provided for distinguishing whether the network node is authorized or not by having an internet protocol address and a media access control address of the ARP packet to be compared with a permission list, and then for permitting the network node to connect with the network segment or for blocking off the network node. Thereby the network system can be protected and the safety of the network in use increases.
