OBJECTIVE To determine the relationship between shift work and mental health, particularly insomnia, depression, and suicidal ideation, among electronics production workers. METHODS A survey was conducted with 14,226 workers from an electronics manufacturer in South Korea. After excluding 112 individuals with incomplete responses, 14,114 respondents were analyzed. As part of a larger project,...

Objective. The purpose of this study was to investigate whether short sleepers (<6 hrs) who worked the non-day-shift were at greater likelihood of reporting hypertension and if these associations varied by individuals' ethnicity. Methods. Analysis was based on the 2010 National Health Interview Survey (NHIS). A total of 59,199 American adults provided valid data for the present analyses (mean a...

AIMS To investigate the effects of shift work on increased alcohol intake associated with poor sleep quality. METHODS This cross-sectional survey evaluated the correlation between work schedule, poor sleep quality and heavy drinking among 909 factory workers aged 35-54 years in Japan. Subjects included 530 day workers, 72 shift workers who did not work at night and 290 shift workers who engag...

There is a manufacturing system where several parts are processed through machining workstations and later assembled to form final products. In the event of disruptions such as machine failure, original flow-shop schedule needs be revised and/or rescheduled. scenario, rescheduling methods based on right-shift affected operations work very well. Here in this study, deviation make-span from used ...

in many signal processing applications, an appropriate measure to comparetwo signals plays a fundamental role in both implementing the algorithm andevaluating its performance. several techniques have been introduced in literature assimilarity measures. however, the existing measures are often either impractical forsome applications or they have unsatisfactory results in some other applications....

Delayed prompting can produce errorless discrimination learning. There is inherent in the procedure a disparity in reinforcement density which favors unprompted over prompted responses. We used three schedules of reinforcement to investigate the impact of reinforcement probability on transfer of stimulus control. One schedule of reinforcement was equal prior to and following a prompt (CRF/CRF),...

The initial proposal submitted in September of 2012 discussing the implementation of the Discontinuous Galerkin (DG) methods and strand methods requires restructuring of the schedule and the deliverables due to difficulties encountered. The original proposal indicated that the one dimensional discontinuous Galerkin flow solver was scheduled to be completed by October 31, 2012, the two dimension...

Cluster computing frameworks such as Apache Hadoop and Apache Spark are commonly used to analyze large data sets. The analysis often involves running multiple, similar queries on the same data sets. This data reuse should improve query performance, but we find that these frameworks schedule query tasks independently of each other and are thus unable to exploit the data sharing across these task...
