Abstract: Proposed are an unsupported metallic catalyst for a selective ring-opening (SRO) reaction and a method of using the same catalyst, wherein the catalyst contains nickel (Ni), molybdenum (Mo), and tungsten (W).

Abstract: The present invention relates to a method for differentiating mesenchymal stem cells into osteoblasts, a cell therapeutic agent for treating bone disease including osteoblasts differentiated by the method and a method for producing the same. In addition, the present invention relates to a method for treating bone disease, including the step of administering the osteoblasts obtained by the method to a patient with bone disease. The differentiation method according to the present invention can stably and rapidly differentiate mesenchymal stem cells into osteoblasts. The differentiated osteoblasts have excellent blood vessel-forming ability and excellent bone-forming ability. Accordingly, the method for differentiating stem cells into osteoblasts and the osteoblasts obtained by the method, according to the present invention, can be effectively used as a cell therapeutic agent or treatment method related to bone disease.

Abstract: Provided are a stem cell-nano anticancer drug complex in which an anticancer drug based on carbon nanotubes (CNT) and gold (Au) nano particles is loaded on the surface of stem cells, which can overcome side effects of conventional stem cells and targeting limitations of nano anticancer drugs and whose anticancer effect is very excellent, the use thereof, and a method for preparing the same.

Abstract: A method for transmitting and receiving messages in a home appliance networking system, wherein a first home appliance connected to a network appends a unique message identification number to a header of a message and transmits the resulting message to a second home appliance connected to the network. Messages transmitted and received among a plurality of home appliances can be distinguished from one another, resulting in a reduction in message transfer errors. Moreover, as needed, a group code corresponding to a specific group of home appliances may be appended to a transmitter message for control of the specific group so that the home appliances can be conveniently and efficiently controlled at one time.

Abstract: A home network system including a protocol converter for converting protocols such that a passive home appliance and a home server connected to a network smoothly communicate signals based on different protocols with each other and a method for operating the home network system. The protocol converter converts a status information signal based on a home appliance protocol from the passive home appliance to transmit it to the home server. The protocol converter converts a control signal based on a home server protocol from the home server to transmit it to the passive home appliance. Therefore, the home server can be compatible with the passive home appliance irrespective of manufacturer and/or protocol of the passive home appliance connected to the network. Compatibility and applicability of the home network system are thus extended and simultaneously the home network system becomes more cost-effective.

Abstract: A system and method for networking home appliances through a multinetwork structure, wherein the home appliances are connected directly or indirectly to a network constructed through a LAN line or power line communication network in a home such that they are operated according to algorithms of different coding/decoding levels. The home appliances construct different networks so that they are efficiently interoperable in the entire network. Therefore, even though an external intruder intrudes into any one of the different networks, information of home appliances connected to the other networks can be prevented from leaking out, thereby avoiding security risks.

Abstract: A method is provided of upgrading the protocol of a networkable home appliance which is manufactured for use in a home network so as to have the ability to communicate through a gateway connected to an external communication network, and that has a flash memory for storing the protocol. The protocol stored in the flash memory is automatically upgraded with a new version thereof simply and conveniently without any waste of time or manpower. The protocol of the home appliance may be updated with the new version of the protocol in a service provision server which provides home appliance information. The version upgrade of an existing home appliance can be performed without a service visit or any manipulation by the user, thereby enabling data compatibility between the existing home appliance and a home appliance newly introduced to the market.

Abstract: A home appliance networking system and a method for controlling the same. At least one home appliance is connected to a network and controlled in response to control information received over the network and transmits its state information and self-information over the network. An agent is connected to the home appliance to recognize the self-information transmitted from the home appliance and manage transmission and reception of all data over the network by the appliance on the basis of the recognized information. A service provider provides additional information regarding the home appliance, not included in the self-information of the appliance, to the agent. If a new home appliance is connected to the network to which other home appliances remain connected, the agent recognizes all information of the new home appliance and manages transmission and reception of all data over the network by the appliance on the basis of the recognized information.
