Abstract: The method of manufacturing an adhesive wall finish includes forming a compressed plastic panel having first and second sides, laminating a deco sheet onto the first side using an adhesive member, wherein the deco sheet is laminated with at least one decorative pattern, obtaining a PE foam sheet having a first side and a second side, forming a first adhesive face on the PE foam sheet by applying an adhesive member to the first side of the PE foam sheet and attaching a release paper thereto, forming a second adhesive face on the PE foam sheet by applying an adhesive member to the second side of the PE foam sheet and attaching a release paper thereto, laminating the second side of the compressed plastic panel with one side of the PE foam sheet through the first adhesive face, and cutting the compressed plastic panel to certain size specifications.

Abstract: A toilet bowl includes a toilet seat, a seat cover and connections which are to be operated by mutually connecting backward tail ends of the seat and backward tail ends of the cover. The toilet seat is integrally formed with egg shaped twin protrusions on a backward tail end central region of the seat by an injection molding process. The twin protrusions include a left protrusion and a right protrusion, top surfaces on the protrusions, a front groove and a rear groove, and a boundary surface formed between the protrusions by grooves. By repeated rocking type motions for the compression and relaxation motions of each of the gluteal muscles of the user on the top surfaces of the seat having the twin protrusions, the user massages lower regions of the rectum of the user in cyclic motions of the rectum as in a conventional massage mode.
