Collaborations among different governmental agencies and multi-disciplines are necessary to establish a forecasting and warning system of geological disasters (FWSGD). A FWSGD in China has been in operation since June 1, 2003 as a joint project between the China Meteorological Administration (CMA) and the Ministry of Land and Resources (MLR). This system has successfully shown very good social and economic benefits. The temporal-spatial distribu- tions of China geological disasters and their causes have been analyzed in this paper. The FWSGD is described and its possible existing issues are also discussed. Authors suggest a new approach to study these disasters from interactions of the earth systems. Finally, a monitoring, forecasting, warning and preventing system for geological disasters in China is proposed.展开更多

Methods: 98 surgical patients who participated in the research work came from our hospital from February to December, 2021, and were randomly divided into two groups, 49 in each group. The nursing modes of the two groups are different. One group adopts conventional nursing mode and the other group adopts refined nursing mode. The psychological state and nursing effectiveness of patients between groups were compared. Results: the observation indexes of the group applying the refined nursing mode were superior to those of the control group (P < 0.05). Conclusion: the application of fine nursing has positive significance in surgical patients, and it is worthy of further clinical application.展开更多
