Country images of Korea and Japan based on economic development, education level, goods' quality, R&D, political democratization and quality of life, perceived by Chinese university students in Beijing, Shanghai and Shandong province of chinese emerging markets as the representative of a potential buying power group, are surveyed, which, then are used to study how the perceived country images effect on their purchasing intention for Korean and Japanese products, such as, foods, cars, fashions, music CDs, electronic products and living goods. The study shows that, in chinese emerging markets, country image affects on the purchase intention of each products differently. The country image of Korea was less influential than that of Japan on the Chines students' purchasing intention for the goods other than the electronic goods. Despite the small number of the sample, this study showed the importance of country image in the in chinese emerging markets and suggested the need for both the government and private sector to take a strategy to enhance the country image by finding the relation between the elements of country image and the intention to purchase certain product.

Artificial life is used in various fields of applied science by evaluating natural life-related systems, their processes, and evolution. Research has been actively conducted to evolve physical body design and behavioral control strategies for the dynamic activities of these artificial life forms. However, since co-evolution of shapes and neural networks is difficult, artificial life with optimized movements has only one movement in one form and most do not consider the environmental conditions around it. In this paper, artificial life that co-evolve bodies and neural networks using predator-prey models have environmental adaptive movements. The predator-prey hierarchy is then extended to the top-level predator, medium predator, prey three stages to determine the stability of the simulation according to initial population density and correlate between body evolution and population dynamics.
