Abstract:
The present invention relates to a method for differentiation of mesenchymal stem cells or dental pulp stem cells. More specifically, the invention relates to a method for differentiating stem cells to neural cells by applying mesenchymal stem cells or dental pulp stem cells with a low-frequency electromagnetic field. The differentiation method according to the present invention can induce differentiation even with low-cost mediums rather than induced neural differentiation mediums which are expensive due to addition of growth factors, and the neural cells differentiated according to the present invention may be useful for treatment of neurological brain diseases.
Abstract:
A method and system for providing asynchronous data communication between a plurality of devices in a networked environment is disclosed. A user using a first device views view media content received from a first content provider of a plurality of service providers. At a request of the user, a message including a data link to the media content is generated and asynchronously sent to a second device via a network. The data link contained in the received message on the second device is used to retrieve the media content from a second content provider. Various action commands contained in the message are used to control the operation of the media content on the second device.
Abstract:
An apparatus for preparing a catalyst for carbon nanotubes using spray pyrolysis and a method for preparing the catalyst are disclosed. The apparatus comprises a plurality of raw material tanks, an agitator to mix raw materials respectively supplied from the raw material tanks, a drier to spray the mixture supplied from the agitator and thus to heat and bake the same, and a storage to store a dried material discharged from the drier. The method comprises supplying a plurality of raw materials, mixing the raw materials with one another, spraying the raw material mixture in a liquid state and drying the same at a high temperature, and storing a catalyst generated in the drying process.
Abstract:
The present invention relates to a hand skin care apparatus for performing multiple functions of drying and cosmetically treating hands, caring hand skin, aiding health, therapeutic activation, and fomentation, therapeutic activation, and fomentation, and employs a cover pivotally opened and closed about a hinge shaft of a main body for sucking air, projecting infrared rays, heating using infrared rays, and projecting laser beams. The introduced air passes through the infrared ray projector and is blown to where a user's hands are placed such that hands are rapidly dried by hot air and heat, infrared rays, and infrared rays generated by the infrared ray projector and the infrared exothermic device prevent and remove the inhabitance of bacteria causing various diseases on the hands. Thus, a user can maintain his/her hands at sanitary state. Due to the increased temperature, the apparatus of the present invention exhibits fomentation and the far infrared rays are helpful to hand skin care and health. Moreover, the low-level laser beam is projected to hands to activate the treatment of affected parts and various hand diseases, resulting in aiding health. Since a single apparatus performs various and multiple functions, the hand skin care apparatus is variously used, has various effects. Moreover, economic value and utility of the hand skin care apparatus are enhanced.
Abstract:
The present invention relates to a method for differentiation of mesenchymal stem cells. More specifically, the invention relates to a method for differentiating mesenchymal stem cells to neural cells by treating the mesenchymal stem cells with low-frequency sound waves. The differentiation method of the present invention can induce differentiation even with low-cost media rather than induced neural differentiation mediums which are expensive due to addition of growth factors, and the neural cells differentiated according to the present invention may be useful for treatment of neurological diseases.
Abstract:
A light guide plate includes a light incident surface, a light facing surface facing the light incident surface, a connection surface connecting the light incident surface with the light facing surface, and a top surface connected with the light incident surface, the light facing surface, and the connection surface. The light incident surface receives light from a light source, the light facing surface reflects light, and the top surface outputs light toward a display panel. The connection surface includes at least two absorption surfaces parallel to a straight line linking a center of an arc with an end of the light incident surface and at least one reflective surface interposed the two adjacent absorption surfaces to reflect the light.
Abstract:
Disclosed is a method and system for controlling access for a mobile agent in a home network environment. The method includes the steps of: issuing a role ticket to the mobile agent; verifying access authority to service requested by the mobile agent through the role ticket; and granting the mobile agent access authority to the service. Accordingly, a table for managing access authority of a user is distributed to devices, so that it is possible to provide the mobile agent access control method and system capable of minimizing network traffic in the home network environment.
