1035 married women workers in three modern textile mills in Anhui, China were surveyed to investigate the association of rotating shiftwork with low birth weight and preterm birth in 1992. Information on reproductive health, occupational exposure history, and other covariates including age at pregnancy, time and duration of leave from job since pregnancy, and mill location was obtained by train...

OBJECTIVE The aim of this study was to identify atherosclerotic risk using pulse wave velocity (PWV) in steel workers employed in different shift-work rotations, and to elucidate its relationship to social jetlag and shift schedule details. PARTICIPANTS Male workers in a steel factory (n=77, 32 fast clockwise (CW), 30 slow counterclockwise (CC), 15 day workers (DW); mean age 42 ± SD 7.6 yrs) ...

The overall structure is one of the most important properties of block ciphers. At present, the most common structures include Feistel structure, SP structure, MISTY structure, L-M structure and Generalized Feistel structure. In [29], Choy et al. proposed a new structure called GF-NLFSR (Generalized Feistel-NonLinear Feedback Shift Register), and designed a new block cipher called Four-Cell whi...

A Linear Feedback Shift Register, or LFSR, can implement an event counter by shifting whenever an event occurs. A single two-input exclusive-OR gate is often the only additional hardware necessary to allow a shift register to generate, by successive shifts, all of its possible nonzero values. The counting application requires that the number of shifts be recoverable from the LFSR contents so th...

There is evidence that work schedules may influence rates of unhealthy behaviors, suggesting that addressing work schedule challenges may improve health. Health Risk Assessment (HRA) survey responses were collected during 2000-2008 in a multinational chemical and coatings manufacturer. Responses of 26,442 were sufficiently complete for analysis. Rates of smoking, lack of exercise, moderate to h...

Shiftwork is one of health care worker's oldest problems and is known to have important implications on health. Health risks are compounded with age and the amount of cumulated shiftwork. No shift system is clearly advantaged, yet the worker's ability to choose the shift system seems to maximize adaptation to shiftwork. When designing a work schedule, it is important to take into consideration ...
