The present invention relates to a method for separating highly active stem cells from human stem cells, the highly active stem cells separated by the method, a cell therapeutic agent containing the stem cells, and a medium for separating the highly active stem cells from stem cells containing a specific cytokine. According to the present invention, the method is useful for separating the highly efficient stem cells from mesenchymal stem cells of various origins. Further, the method is very useful in developing a cell therapeutic agent of high efficiency because the method can be applicable to stem cells of various origins which are cultured under different conditions. Senescent stem cells increased by several passage times in vitro can be effectively sorted out, so the method can be used for reactivating the stem cells.

An anode for a lithium ion secondary battery includes an anode, and a LiF-based coating layer formed with LiF-based particles on a surface of the anode. The LiF-based coating layer has a thickness of 0.05 to 1 μm. The anode allows the LiF-based coating layer created by side reaction of LiPF6 during a battery charging/discharging process to be relatively uniformly formed on the anode surface, thereby elongating the life cycle of a lithium ion secondary battery.

Disclosed is an antioxidant fermenting microorganism agent and a polyurethane foam including the same. The antioxidant fermenting microorganism agent is used to generate a substance that is capable of reducing an amount of volatile organic compounds generated from the polyurethane foam and has an antimicrobial ability. The polyurethane foam containing the antioxidant fermenting microorganism according to the present invention can be used as the material for the interior of a vehicle to protect humans from noxious substances causing sick car syndrome.

A method and apparatus for domain name autoconfiguration in an IP-based wireless sensor network is provided. The method includes: receiving sensor node information including position information for representing an installed position of a sensor node, a type of data to be provided by the sensor node, and an internet address of the sensor node; searching for area information including an administrative address corresponding to the position information of the sensor node; generating a domain name of the sensor node based on a type of the sensed data and the found area information; and binding the generated domain name with an internet address of the sensor node and registering the bound result in a domain name server.
摘要:
A pharmaceutical composition for the treatment of malignant tumors comprising a human p31comet gene encoding protein represented by SEQ ID NO: 3 or 4 as an effective component is provided. The pharmaceutical composition can suppress cancer cell growth, induce apoptosis and kill cells by overexpressing p31comet in the solid malignant tumor cells. Therefore, the pharmaceutical composition can be effectively used for gene therapy.

Provided are a bridge system, a network management server, and communication methods at the bridge system and the network management server for efficient communication in a wireless sensor network (WSN). The communication method at the network management server includes communicating with bridge systems connected with a plurality of radio frequency (RF) regions within a personal area network (PAN) composed of sensor nodes using the same wireless channel, in which radio signals of the sensor nodes within the PAN reach the bridge systems, searching for a new channel to be used and an alternative bridge system which is to perform a channel change into the new channel based on information about the bridge systems upon receipt of an association failure report message from an error bridge system which is reported of an association failure from the RF region from among the bridge systems, sending a channel change request message to the found alternative bridge system, and adjusting channel information for the found alternative bridge system to the new channel and replacing information about sensor nodes connected to the found alternative bridge system with information about sensor nodes that are newly connected with the found alternative bridge system through the new channel.

Provided are a system and method for guiding a visitor using a sensor network. The system includes: an entry approval requesting unit for requesting an entry approval of the visitor to the visitee terminal according to destination information; a route setting unit for setting a route along which the visitor terminal is to move to the destination, based on the destination information of the visitor, according to an entry approval result of the visitee terminal; a location detecting unit for detecting a current location of the visitor terminal based on identification information of the visitor terminal and location information of the sensor node, the identification information and the location information being obtained through the sensor network on the route; and a location confirming unit for confirming if the detected current location of the visitor terminal is out of a preset area.
摘要:
An information service system using USN nodes, a network and a service server connectable to ubiquitous sensor network (USN) nodes through the network are disclosed. The information sensed by the USN nodes is transmitted to the service server connected to an external network, so that an administrator can check the context of surrounding environment where the USN nodes are installed, through the service server. The operation command for a specific object associated with a specific USN node, input by an administrator accessed the service server, is transmitted to the USN node via the network, so that the USN node can operate the specific object. The USN can be established at relatively small size, reducing installation costs, maintenance fees, and resource waste. Thus, the USN can be widely used in the applications.
