Abstract: The present invention relates to a scaffold for artificial organs using a water-soluble non-degradable acrylic polymer and a water-insoluble non-degradable acrylic polymer, which are acrylic synthetic polymers, and a preparation method thereof. The acrylic monomer or polymer-based scaffold of the present invention improves the disadvantages of the natural polymer-based scaffolds, allowing degradation of specific sites in vivo and easy cell adhesion, and since it is possible to control mechanical properties, it is possible to implement mechanical properties and morphology suitable for where to use and purpose of use. In addition, the present invention can be applied as a bio material for artificial organs such as artificial cornea, artificial liver, artificial heart, artificial cartilage or artificial bone tissue, which requires maintenance of physical properties, high cell compatibility and stability in the body.

Abstract: Disclosed is a base assembly for a video display appliance capable of receiving a keyboard within a front thereof, as well as easily adjusting a tilting angle and a swiveling angle of a monitor. The base assembly comprises an upper base cover integrally formed with a lower portion of the monitor; a lower base cover coupled to the upper base cover and having a hinge accommodating opening on a center thereof; a tilting angle adjusting mechanism, coupled to the upper base cover and provided in the hinge accommodating opening of the lower base cover, for tilting the monitor by applying an operating force to the monitor upwards or downwards; and a swiveling angle adjusting mechanism for rotating the monitor, the upper base cover coupled to the monitor, and the lower base cover in a left or right direction.
