Abstract: A method for displaying suggested items associated with a message, the method, which performed by at least one processor, includes: based on a preset first keyword that is detected in a message that is input to an input window of a chat room, displaying suggested items comprising a conversation group or a content associated with the preset first keyword, wherein the conversation group corresponds to a reception target of the message; and based on an item selected from the suggested items, displaying the message comprising information on the conversation group or the content corresponding to the selected item.

Abstract: Provided is a method for providing a recommended chat room for sending a message. The method, which is performed by at least one processor, includes: identifying a user matching a name entered on a message writing screen; and providing a recommended chat room list in which at least one chat room having the user is displayed.

Abstract: An electroluminescent device includes a first electrode and a second electrode facing each other; an emission layer disposed between the first electrode and the second electrode and including a plurality of quantum dots and a first hole transporting material having a substituted or unsubstituted C4 to C20 alkyl group attached to a backbone structure; a hole transport layer disposed between the emission layer and the first electrode and including a second hole transporting material; and an electron transport layer disposed between the emission layer and the second electrode.

Abstract: Provided is a method of preparing a red clay processed material using red clay and sodium hydroxide and a red clay processed material having anti-corrosive and virus disinfecting activity. Also, a method of preparing alkali ionized water having excellent anti-bacterial, virus disinfecting and anti-corrosive activity using the red clay processed material, alkali ionized water using the same, and a functional product including the same are provided. The red clay processed material and the method of preparing alkali ionized water using the same can reduce the reaction temperature and reaction time compared to a conventional process, thereby significantly reducing the production cost.

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: 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.
