Abstract: The present disclosure relates to a technology of producing a sculpture in a 3D stereoscopic space filled with a transparent material. The sculpture may be produced through a process of preparing a desired number of 2D plans acquired by dividing a 3D plan of the sculpture and a plurality of transparent plates corresponding to the number of the 2D plans, forming the shapes of corresponding regions by stacking representation materials on the corresponding transparent plates, joining the representation materials to the corresponding transparent plates, or making scratches on the corresponding transparent plates, and stacking the transparent plates having the shapes formed thereon, and can precisely represent shapes through various representation techniques or be repeatedly reproduced.

Abstract: A bag for a notebook computer which allows easy use of the computer while still maintained in the computer bag. The bag includes a body for receiving a notebook computer therein, and a cover pivotally coupled along one side to the body to enable opening motion of the cover. The bag further includes an angular motion restraint which couples the cover of the bag to the body of the bag, so that the cover opening approximately corresponds to the opening of the computer display panel. In one embodiment of the invention, the angular motion restraint includes a restraining band. The restraining band has one end fixed to the body of the bag and the other end fitted with a first fastener part. The first fastener part of the restraining band is attachable to a second faster part which is attached to an inner surface of the cover.
