Despite the national decline in the number of employed workers in 1975, the number of workers covered lnder most types of employee-benefit plans increased slightly. Contributions and benefit payments underwent the greatest change. Total contributions increased 17 percent and benefit payments rose 14 percent. In part this change can be attributed to inflation, but it also reflects real growth in...

climate change is one of the most important factors that will affect different parts of human life on earth and will be adverse effects on environmental resources, economic, social and especially water resources, with changes in rainfall and timing of runoff amount.one of the strategies to mitigate the effects of climate change is to assess its effects on precipitation, temperature and runoff i...

[1] Assessing the sensitivity of annual streamflow to precipitation is challenging due to the complexity of the processes that control the water balance. A low-dimensional model can be useful to interrogate data in regional assessments of a large number of catchments, and can provide insights into the broad similarities and differences between catchments’ behaviors. This work assesses the sensi...

Pediatric thyroid carcinoma is relatively uncommon. But variability in incidence rate by race, sex, age at onset/diagnosis, and geographic local had been observed in adult thyroid carcinoma in the USA. We aimed to examine the patterns, rates, and temporal trends of thyroid carcinoma among pediatric patients (0-19 years) between 1973 and 2007. The Surveillance, Epidemiology, and End Results (SEE...

BACKGROUND AND PURPOSE Stroke is the second leading cause of death in Japan. We sought to examine changes in stroke mortality rates by age, sex, and birth cohorts from 1950 to 1997. METHODS The numbers of deaths from stroke and the population by age and sex in subjects aged 55 to 79 years between 1950 and 1997 were obtained from national vital statistics. Poisson regression analyses for annua...

The semiconductor industry plays an important role in Taiwan’s economy. In this paper, we constructed a rolling Grey forecasting model (RGM) to predict Taiwan’s annual semiconductor production. The univariate Grey forecasting model (GM) makes forecast of a time series of data without considering possible correlation with any leading indicators. Interestingly, within the RGM there is a constant,...
