On the Issue of Predicting the Strength Characteristics of Dispersed-Hardened Polymeric Composite Materials at the Design Stage of Engineering Products Notin Ilia1, a 1Bauman Moscow State Technical University (BMSTU, 105005, Moscow, Russian Federation, 2nd Baumanskaya St., Bldg. 5, Block 1 ainotin@ya.ru Keywords: particulate filled polymeric composite materials, strength characteristics, composite materials, mechanical engineering, machine building technology Abstract.
The use of new promising materials allows achieving higher operational and technological characteristics of the final product.
Thus, a significant reduction in time and material costs at the stage of preparation of production of products from dispersed-reinforced polymeric composite materials is possible.

Diffuse reflectance Light on Surface of Biological Material Lianshun Zhang, Wenli Liu College of Science, Civil Aviation University of China Tianjin, China zhangls1963@yahoo.com Keywords: Biological material; Diffuse reflectance; Diffusion equation; Monte Carlo simulation.
Introduction Light propagation in biological material is determined by the optical properties of the material.
The absorption coefficient, scattering coefficient of material reflect the physiological state of material, such as blood sugar and oxygenation as well as possible diseases[1, 2].
Many hundreds of papers concerning DA have been published in journals and conference proceedings during recent years [4].

When observing from the history of human and society development, we can easily conclude that material sciences and product manufacturing stimulate each to evolve and improve.
When these materials are harm-free and can replace the materials such as plastic or chemical fiber, they are often given as potential candidates for environment-friendly materials.
Moreover scientists are advancing complex functions in materials and are making materials more "intelligent".
Conclusion As the science and technology evolve, product designers will have more choices in product materials.
At the same time, the involvement of the science and technology and creativity of the new materials causes a deeper thought and introspection to human design activity in itself.
