UNESCO Global Geoparks are single, unified geographical areas where sites and landscapes of international geological significance are managed with a holistic concept of protection, education and sustainable development. The UNESCO Global Geoparks are obligated to promote awareness of key issues facing society including increasing the knowledge and understanding of the story of the planet as read in the rocks, landscape and ongoing geological processes by educating the local communities and visitors of all ages. In the process of disseminating geological knowledge to the general public, the explanation board in the geoparks plays a very important role. However, the content of the explanation board often contains many geological terminologies which are too difficult for the general tourists and the local people to understand. The difficulty level of the explanation boards which provide geological knowledge to the general public has a great influnce on the attractiveness of the signboards and also on the effectiveness of the knowledge dissemination. Therefore, in order to figure out the issue that the contents of signboards might be too difficult for the general public based on the common geological knowledge level of Chinese people, the purpose of this study is to clarify the gap between the contents of the signboards in Zhangjiajie Global Geopark and the geological knowledge level of the general public. This study attempts to make a comparative analysis between the geological terminologies appeared in the content of explanation boards in Zhangjiajie Global Geopark and the terminologies in the compulsory geological teaching materials of high school and middle school which is the most prevalent way for most people to get the geological knowledge in China., Art and Design Research for Sustainable Development ; September 22, 2018 Conference: Tsukuba Global Science Week 2018 Date: September 20-22, 2018 Venue: Tsukuba International Congress Center Sponsored: University of Tsukuba

A dynamic parameters model is established based on cellular automata (CA) to simulate pedestrian evacuation in this article. The dynamic parameters are formulated to simplify tactically the decision-making process of pedestrians, which can reflect the pedestrian judgment on the surrounding conditions and determine the pedestrian's choice of action. The pedestrian moving rules are proposed according to two-dimensional cellular automaton Moore neighborhood. The simulation results of this model are compared and analyzed with previous model. It is clear that our model corresponds with the actual and shows the advanced nature. The evacuation time versus pedestrian density and exit width are studied. There is a linear relationship between evacuation time and pedestrian density, whereas there is a nonlinearly relationship (negative exponential) between evacuation time and exit width. Moreover, the authors consider the effects of the crowd distribution in evacuation process, and the optimal exit layout is given in a determined system, such as the optimal position and width of exits, providing safety guiding for the pedestrian in enclosed environments, and avoiding and/or reducing the number injuries.
