ABSTRACT
Objective To establish a scientific, operational monitoring and early warning index system for schistosomiasis, so as to provide scientific evidence for promoting the scientification and standardization of early warning system in Poyang Lake Eco-economic Region. Methods Two rounds of Delphi experts’ interviews were applied to construct Index system. The weight value of each indicator was determined by the Analytic Hierarchy process and improvable proportionate allocation method. Reliability, validity of index system and the rationality of index weight distribution can be evaluated in site investigation. Results The Index system included 3 first-order indicators, 9 second-order indicators, and 35 third-order indicators. The 3 first-order indicators were endemic status, environmental and social factors, control measures, with the weight value of 0.531 0, 0.101 5 and 0.367 5, respectively. For the 9 second-order indicators, the highest weight value was for Infection status of human and livestock (0.179 5)and the lowest for social factors(0.050 6). During site investigation, the Cronbach’s alpha and spit half reliability of the total index system and three first-order indicators were all over 0.90, the Kendall W coefficient for the data collected in site investigation and Delphi consultation was 0.742 (P=0.018). Conclusions The Monitoring and Early Warning Index System for Schistosomiasis is suitable for the infection status of Poyang Lake Eco-economic region. The reliability and validity of index system are satisfactory, and the indicator weight distribution is rational.
ABSTRACT
“Tianjin Port 8·12 Catastrophic Explosion Accident” is making us alert. And how to learn lessons from the accident, how to form effective prevention and control strategies, which make us much ponder over. Based on summarizing the experiences of the previous chemical emergencies, from the aspects of monitoring and early warning, disaster assessment, on-site detection, and remote telemetry, this paper expounds the importance of the related mechanism and the hardware construction. Then the serious “bottleneck” in the construction of Chinese chemical defense was pointed out as well as introducing the new development direction of foreign military monitoring and detecting equipments. Our aim is attracting much attention of peers within the discipline, so as to effectively enhance the abilities of monitoring and early warning and emergency handling for chemical defense in China.

ABSTRACT
Chemical threat is a serious public safety problem we must be facing. And how to effectively deal with it is a priority. Based on the needs of chemical defence in our country, "hierarchical monitoring" technology platform is proposed. From three aspects of monitoring and early warning, on-site detecting and laboratory confirmation, and the international development needs and trends, the comparation of domestic and foreign equipment construction and development suggestions in our country are discussed and reviewed. Our aim is to establish effective monitoring mechanism for chemical defence, so as to nip the chemical threat in the bud or reduce the chemical hazards to the minimum.
