The ideal mannequin should be durable, low cost, giving direct feedback to examiner, and can be produced using local material [2,3].
Material and Methods Gynecology Bimanual Examination Mannequin We made pelvic torso model mannequin which consists of pelvic cavity with right and left thigh based on anthropometric measurement [4].
For further improvements, we still need to determine the degree of hardness of the material, elasticity of the skin, durability of the mannequin and consistency of the circuit system.

High-purity raw materials such as LiF, YF3, and NdF3 (99.99%, Aladdin), were used in this process.
Therefore, the molar ratio of LiF: YF3: NdF3 in the feed materials was adjusted to 52:47:1.

It affects the flowing of material of expanding section and leads to the decrease of wall thickness.
For the large value of radius of round angles, the flow resistance of material is small and flow deformation occurred easily.

By-product materials such as fly ash and slag are significant sources of aluminosilicate materials in addition to the naturally occurring raw materials.
The fly ash based geopolymer shows greater resistance to the aggressive materials than the OPC concrete [2].
Experimental Work Materials: Low calcium Class F (ASTM C 618) fly ash was used for making geopolymer concrete.
The alkaline activator solutions were mixed together prior to adding to the dry materials.

The higher resistance against deformation that these materials possess provides the desired stability of the auto body in crash situations but also leads to higher mechanical and tribological loads on the forming tools during the production process [1].
Tool Selection It was necessary to use superabrasive cutting materials (diamond or cBN) because of the high amount of tungsten carbide in this coating.
The high grain protrusion and the very low amount of bonding material (except of the identical nickel-plating) permitted the comparison of diamond and cBN grain as cutting materials, with a minimum influence of the bonding system.
The index xx% stands for the boundary material fraction value.
