Musculoskeletal disorders (MSDs) are a significant cause of morbidity in healthcare workers. The influence of shift work and long work hours on risk for MSDs is an area that needs further exploration. The purpose of this report is to assess research progress and gaps across studies that examined the relationship between demanding work schedules and MSD outcomes. A literature search identified 2...

a project is any endeavor involving planned action, for example, developing a new product or constructing a dam. [ce1] major factors for a project to be successful are applying performance measurement and feedback tool. one such well-known performance measurement tool to control the project execution is earned value management (evm). evm uses the fundamental principle that trends in the past ca...

Prior studies on alternative work schedules have focused primarily on the main effects of compressed work weeks and shift work on individual outcomes. This study explores the combined effects of alternative and preferred work schedules on nurses' satisfaction with their work schedules, perceived patient care quality, and interferences with their personal lives.

background: today, obesity is considered as a health problem that increases the risk of some diseases. therefore, identifying the effective factors on obesity is of great importance. shift work is one of the indicators for increased risk of obesity in society and also shift work may cause various health problems for workers in military organizations. the current study aimed to investigate the r...

OBJECTIVES The aim of this study was to compare the psychophysiological strain related to a conventional shift schedule and new ergonomically improved two- and three-shift schedules using heart rate variability (HRV) analysis. The specific aim was to determine whether the introduced ergonomic shift arrangement had any positive effects on the psychophysiological strain such as increased HRV or d...

OBJECTIVES Existing research has documented that shiftwork consequences may depend on the shift system parameters. Fast rotating systems (1-3 shifts of the same kind in a row) and day work have been found to be less disruptive biologically and socially than slower rotating systems and afternoon and night work. The aim of this study was to compare day workers and shift workers of different syste...

BACKGROUND/AIMS The aim of this study was to investigate the role of psychosocial problems and their associations with rotating shift work in the development of functional gastrointestinal disorders. METHODS In this cross-sectional observation study, survey was administered to nurses and nurse assistants in a referral hospital. In addi-tion to demographic questions, subjects were asked to com...

⎯In the previous work of garbage collection (GC) models, scheduling analysis was given based on an assumption that there were no aperiodic mutator tasks. However, it is not true in practical real-time systems. The GC algorithm which can schedule aperiodic tasks is proposed, and the variance of live memory is analyzed. In this algorithm, active tasks are deferred to be processed by GC until the ...

Actual working hours of employees vary widely, especially in the transportation industry. We developed a tool, the RAS (Representation and Analysis Software), to ease the assessment of such irregular hours and the transfer of existing knowledge of proper schedule design to the problem of irregular hours. This article discusses several critical design questions that were addressed during softwar...

This paper develops a model of activity and trip scheduling that combines three elements that have to date mostly been investigated in isolation: the duration of activities, the time-of-day preference for activity participation and the effect of schedule delays on the valuation of activities. The model is an error component discrete choice model, describing individuals’ choice between alternati...
