Optimization of a Reinforcing-Rib Design for ABS and High Glossy Surfaces of Plastic Parts SeongWon Jeong Dept. of Product Design and Manufacturing Engineering, Seoul National University of Science and Technology, South Korea swjeong@seoultech.ac.kr Keywords: Rib, Rib Design, Injection Molding, ABS resin, Response Surface Methodology Abstract.
Material for the Experiment We created a plate-type plastic part [Fig. 1] that was 10 cm in width by 10 cm in length using ABS resin and an injection mold in order to compare the actual amount of shrinkage caused by ribs while varying the condition of the ribs.
The material used to create the mold is CENA1[7], which is generally used to create a mirror-like finish.
This study examined the each effect of variable and the interaction between them within the limit of the ABS material and a high glossy surface.

It should be noted that both Δρbp and τ parameters are not material properties and should depend on the macroscopic growth rate and local temperature, which theoretically should affect the nitrogen pile-up in front of a moving atomic step, since we are dealing here with adsorption-diffusion problem, where diffusion of nitrogen occurs both (1) between the bulk of the gas phase and the growth surface and (2) within the adsorbed layer, away from atomic steps invading terraces and pushing adsorbed nitrogen resulting in the near-step nitrogen pile-up we described in the previous paragraph.

Experimental 1.1 Materials Maize starch was obtained from Hengren Trade Co.
Because the reactive dye was formed a bridge between the cellulose material and the thickener so that thickener couldn’t be easily washed, which led to a poor fabric softness performance.

Biomaterials science is a relatively young discipline, still experiencing a steady growth in developing new materials and testing new techniques.
Tissue engineering – progenitor cells and/or bioactive molecules are seeded on three-dimensional modified and absorbable materials (scaffolds).
The bioactive implanted materials then release bioactive molecules at a controlled speed, activating in this way cells and their interactions.
At the same time, synthetic materials are ever more used since their structural and architectural features can be checked during the production phase.

Investigation of Consumer-oriented Product System Design Xiaoqing Hu1,a, Yunfang Gao2,b 1Anhui University of Science and Technology, Shungeng Road 168#, Huainan, China 2Xingtai Polytechnic College, steel north Road 552#, Xingtai, China aEmail: huxiaoqing1976@163.com，bEmail:272312082@qq.com Keywords: consumer; product system design; design method; kansei system Abstract：This paper deeply discussed consumer kansei system and demand, based on Kansei Engineering system; it researched method of product system design.
Designers base on consumer emotional demand, use their design knowledge to create a specific form of product system; On the other hand the new product system created by designers will also induce consumers’ kansei system to receive it, and then guide consumers for buying decision. 2.1 Method of product system design basing on decision aid system of consumers Now consumer demand level has been from the pure material consumption level up to mentally satisfying level.

Since reform and opening, China has been developing cultural “soft power” while developing the “hard power” such as economy, science and technology and national defense.
As things go, to build a green consumption pattern, we should begin with the following aspects: redouble our efforts to achieve energy recycling to reduce raw material and energy consumption; make consumers consciously choose environmentally friendly products and guide enterprises to provide environmentally friendly products through acts of green consumption; change people's consumption patterns by changing the way we manufacture and establish sustainable traffic patterns, residential patterns and luxury goods consumption patterns[2].
