Abstract: A helmet is disclosed. A helmet according to an exemplary embodiment of the present invention may include: a helmet body capable of surrounding a user's head; a fixing member which is fixed to a side surface of the helmet body and has a cam seat part; a movable member coupled to the fixing member so as to be linearly movable forward or backward; a pivot member which has a cam pivotally seated on the cam seat part and is disposed to be engaged with the movable member so as to be pivotable around the cam as a pivot axis; and a pressing member disposed in the fixing member to elastically support the cam and press the cam backward, wherein when the pivot member pivots from a first position toward a second position, the pivot axis moves forward and the pivot member and the movable member are accordingly displaced forward.

Abstract: The present disclosure provides a method of deriving and maintaining a midbrain-like organoid in culture, comprising (a) culturing pluripotent stem cells to obtain neuronal lineage embryoid bodies; (b) culturing the neuronal lineage embryoid bodies from (a) to obtain midbrain regionalized tissues; (c) embedding and culturing the midbrain regionalized tissues from (b) in an extracellular matrix to obtain neuroepithelial tissues; and (c) culturing the neuroepithelial tissues from (c) to obtain a midbrain-like organoid.

Abstract: The present invention provides human striatal-like organoid (hSLO) similar to a huma striatum, a fusion organoid of hSLO and human midbrain-like organoid (hMLO) having functional connections between the hSLO and hMLO, and method of testing drugs using the organoids culture platform.

Abstract: A mobile terminal comprises: a first frame including a first side surface; a second frame which can slide from the first frame in a first direction or a second direction that is opposite to the first direction, and which includes a second side surface that faces the first side surface; and a slide bar which is located between the first side surface and the second side surface and which extends in the first direction.

Abstract: A rollable mobile terminal comprises: a rolling part bent in a first direction and comprising a flexible display unit and a flexible frame which is bent and located on the rear surface of the flexible display unit; a first body having a cylindrical accommodation part in which one side of the rolling part in the first direction is rolled and stored, and an opening formed in one side thereof through which the rolling part enters and is withdrawn; and a second body to which the other side of the rolling part in the first direction is coupled, wherein the rollable mobile terminal can be changed into a state in which the rolling part is accommodated in the first body, and the first body and the second body are closed, or a state in which the rolling part is withdrawn to the outside and the first body and the second body are separated from each other and open, and, even when the flexible display unit is unrolled, the flexible display unit is stably supported such that a display device is supported and a touch input

Abstract: A mobile terminal includes a first frame; a second frame coupled to be movable in a first direction from the first frame, and comprises a third rear unit moving along the back surface of the first frame, and a first roller on the end part in the first direction of the third rear unit; a flexible display having one end fixed to the front surface of the first frame, and covering the first roller; a drive unit moving the second frame in the first direction or moves same in a second direction opposite direction from the first direction; and a connection band covering the end part in the second direction of the third rear unit, has one end thereof connected to the end part in the first direction of the first frame, and has the other end thereof connected to the other end of the flexible display.
