Study of Commercial Bank risk monitoring Model in Individual Consumption Credit

引用

Journal of Donghua University(English Edition) 2003年第2期20卷 125-128页

作者：刘春红 International Culture Exchange School Donghua University Shanghai 2000051ith the development of individual consumption credit (ICC) in China commercial banks have been exposed to more and more risks. The loan failure has been an important problem that the banking must face and revolve. This paper develops a factor system to explain how the borrower's risk is affected and then establishes a risk monitoring model with AHP to pre-warn the banks how much the risk is.

Next Generation Scanning LIDAR Systems for Optimizing Wake Turbulence Separation Minima

引用

雷达学报（中英文） 2017年第6期6卷 689-698页

作者： Ludovic Thobois Jean-Pierre Cariou LEOSPHERE

Numerous studies have been performed to better understand the behavior of wake vortices with regards to aircraft characteristics and weather conditionsover the pastten years. These studies have led to the development of the aircraft RECATegorization(RECAT) programs in Europe and in USA. Its phase one focused on redefining distance separation matrix with six static aircraft wake turbulence categories instead of three with the current International Civil Aviation Organization(ICAO) regulations. In Europe, the RECAT-EU regulation is now entering under operational implementation atseveral key airports. As proven by several research projects in the past, LIght Detection And Ranging(LIDAR) sensors are considered as the ground truth wake vortex measurements for assessing the safety impact of a new wake turbulence regulation at an airport in quantifying the risks given the local specificities. LIDAR's can also be used to perform risk monitoring after the implementation. In this paper, the principle to measure wake vortices with scanning coherent Doppler LIDARs is described as well as its dedicated post-processing. Finally the use of WINDCUBELIDAR based solution for supporting the implementation of new wake turbulenceregulation is described along with satisfyingresults that have permitted the monitoring of the wake vortex encounter risk after the implementation of a new wake turbulence regulation.

Perchlorate and chlorate are ubiquitous pollutants that can adversely affect the thyroid function in *** study assessed the potential health risks associated with the dietary exposure of infants and young children to perchlorate and chlorate present in infant formulas available in *** assessment was based on risk monitoring data from 150 samples of infant formulas in Shanghai between 2020 and 2022,along with the dietary consumption data of infants and young *** detection rates of perchlorate and chlorate in infant formulas were 46.0%and 98.7%,with mean contents of 9.98μg/kg and 112.01μg/kg,and the maximum values of 151.00μg/kg and 1475.00μg/kg,*** mean and 95th percentile(P95)values of daily perchlorate exposure of 0-36-month-old infant and young children via infant formulas were 0.07 and 0.17μg/kg body weight(bw)per day,respectively,which were lower than the tolerable daily intake(TDI)of perchlorate(0.3μg/kg bw per day).The mean and P95 values of chlorate exposure via infant formulas in 0-36-month-old infants and young children were 0.83 and 1.89μg/kg bw per day,which were lower than the TDI of chlorate(3μg/kg bw per day).The P95 exposure of different age groups(0-6 months,7-12 months and 13-36 months)of infants and young children to perchlorate and chlorate in infant formulas was below the ***,the risk associated with the exposure of 0-36-month-old infants and young children to perchlorate and chlorate from infant formulas in Shanghai is considered *** environmental pollution control efforts to reduce the levels of perchlorate and chlorate in food products is important to safeguard the health of the infants and children under the One Health concept.
