Evaluation Of The Cognitive Impairment Caused By Radiation Based On Dynamic Fuzzy Sets

Ionizing radiation occurs in our life. Incidence of nervous system diseases caused by Chernobyl catastrophe such as intelligence impediment, anxiety dumps are still increasing; Astronaut may get cognitive damage duo to the influence of cosmic radiation.This paper is a Cross-over studies between Radioactive Medicine, Dynamic Fuzzy Math, Computer Technology. The mainly work is as follows:(1)We gave a research on Dynamic Fuzzy Synthetic Evaluation method and make a summary of related technology.(2)We enhanced the process of the single factor evaluation, introducing the data processing method, and proposed a method of confirming the Degree of Membership which is based on "Experience+Clustering".(3)We applied the enhanced Dynamic Fuzzy Synthetic Evaluation method to an instance of Cognitive impairment in rats, and established a model of Cognitive impairment caused by radiation in rats.In summary, this paper presented a model of evaluating the cognitive impairment caused by radiation based on Dynamic Fuzzy Sets. This model supplied a new method for researching cognitive impairment by using computer technology. However, considering the complexity of this problem, there are still some problems remaining to be further studied, such as "Learning+ Inference" mechanism in evaluation.
