The paper explains the impact of cultural potential energy to non-conservation spread between the Olympic culture and the culture of Olympic Games host country,and analyzes the culture of Olympic host country spreading global through putting itself into the Olympic culture,thereby to complete the cultural potential energy changes from disadvantaged culture to the strong culture.

The article discusses the relationship between SARS transmission and IAQ in hospitals,suggests some improvement measures for IAQ in hospitals and SARS infection control measures,and introduces some related standards.

The Study of Mobile Location Algorithm with NLOS Error Mitigation;

The simulation results indicate that the location accuracy is significantly improved and the performance of this algorithm is better than that of TDOA location algorithm and AOA location algorithm in NLOS environment.

The main idea is based on a location algorithm of time difference of arrival(TDOA)and considering the influence of non-line-of-sight(NLOS).

The RBF neural network is made use of to correct the measurement of TDOA to mitigate the effect of the non-line-of-sight(NLOS) propagation,then the position of MS is calculated by the TDOA location algorithm and AOA location algorithm,and finally the position of MS is determined by the weighted average of TDOA and AOA location results.
