Prolonged standing can cause discomfort on the body of the workers and can lead to injury and occupational disease. One of the ergonomic intervention is through improving the work-rest scheduling. The purpose of this study are to identify the fatigue level from the perception of the worker and to investigate the impact of the work-rest scheduling to the standing workers for 12 hours working time with a different gender. This study involved two methods which are self-assessment of the worker and direct measurement by using electromyography (EMG)...

Home oxygen therapy (HOT), also known as long-term oxygen therapy, is prescribed to patients with chronic respiratory failure (CRF) due to advanced respiratory diseases, as it has been shown to improve the prognosis of patients with chronic obstructive pulmonary disease (COPD). However, the therapeutic impact of HOT does not fully reflect the "socialization" of patients, which is one of the final goals of "comprehensive pulmonary rehabilitation", proposed by the Japanese Respiratory Society...

To reduce the muscular exertion of an operator wiring terminal blocks on a vertical plane, a chair with a unique back that can be used as a back support or arm support is proposed in this study. A digital version of the chair was first developed based on anthropometric data and tested with a digital anthropometric subject using the Jack software before the physical chair was developed. To evaluate the effects of the physical chair, an experiment of wiring terminal blocks was conducted with 12 subjects to test whether the use of the arm support can reduce muscular exertion...

An important factor for which work and family compete is time. Due to lack of evidence, I investigated the associations between work-family conflict (assessed by the National Study of Midlife Development in the US) and sleep disorders (assessed by the Jenkins Sleep Questionnaire) in a cross-sectional study included 1,021 Egyptians aged 18-59 years. Both work-to-family (WFC) and family-to-work (FWC) were associated with reduced sleep quantity. Moreover, high WFC was associated with sleep disorders; the multivariable ORs (95% CIs) were 2...

This study assessed the relationship between occupation and Intracerebral Hemorrhage-related deaths and compared the differences in ICH-related deaths rates between the eastern and midwestern regions of Inner Mongolia. We used the case-control method. Cases included Intracerebral Hemorrhage-related deaths that occurred from 2009 to 2012 in Inner Mongolia while controls included non-circulatory system disease deaths that occurred during the same period. Odds ratios (ORs) for Intracerebral Hemorrhage-related deaths were calculated using logistic regression analysis, estimated according to occupation, and adjusted for marital status and age...

Shift work leads to adverse health outcomes including increased risk of cardiovascular disease. Heart rate (HR) and heart rate variability (HRV) are measures of cardiac autonomic activity and markers of cardiovascular disease and mortality. To investigate the effects of shift work on cardiac autonomic activity, we assessed the influence of simulated night work on HR and HRV, and dissociated the direct effects of circadian misalignment from those of sleep displacement and altered physical activity patterns. A total of 29 subjects each participated in one of two in-laboratory, simulated shift work studies...

Personal protective clothing (PPC) is mandatory in hazardous industrial workplaces, but can increase thermophysiological strain, causing fatigue, reduced productivity, illness and injury. We systematically reviewed the literature on PPC and heat stress, focusing on research relating to working conditions of high temperature and humidity. PPC must protect industrial workers from a wide variety of hazards, including sun damage, abrasion, chemical spills and electrical burns; these competing demands inevitably compromise thermal performance...

The study objectives were to develop a Japanese-language version of the Feedback Environment Scale (FES) that is used, mainly in the West, as a multifaceted instrument to evaluate the workplace feedback environment, and to test its reliability and validity in the Japanese workplace. The FES (comprising Supervisor and Coworker FES) was translated into Japanese and reviewed through a back-translation process involving the original author to produce the FES-J. Data on 416 individuals working at Japanese companies obtained through internet research were used to investigate FES-J reliability (internal consistency) and validity (confirmatory factor analysis and correlation analysis)...

This study aimed to evaluate personal exposures of 27 workers to indium compounds as "total" dust and its "respirable" fraction in their breathing zones at 3 Japanese indium plants. Eight-hour time-weighted average (TWA) indium concentrations of personal exposure to dust collected in sampling periods of 6 hours or longer were determined by ICP-MS. The arithmetic means of exposure concentrations were 0.095 mg indium (In)/m3 , when sampled as total dust, and 0.059 mg In/m3 , as respirable fraction...

Leisure-time physical activity (LTPA) and dietary energy intake are two important health behaviours, which at too low or high levels respectively, are associated with overweight and obesity. This study explores associations between subscales of the Job Demand-Control-Support (JDCS) model, LTPA and dietary energy intake. A cross-sectional design sampled current employees (N=433) from a South Australian cohort using a computer-assisted telephone interview and a self-completed food frequency questionnaire. In analyses adjusted for sex, age, and sociodemographic variables, higher levels of skill discretion were associated with increased odds for attaining sufficient physical activity (OR=2...

Emotional exhaustion and innovation at work are two major topics of interest to organization researchers, employees and employers. However, working conditions that foster innovation may also heighten employees´ emotional exhaustion. By conducting a two-wave, longitudinal online study among the German working population (N=320), we analyzed the longitudinal impact of qualitative overload, unreasonable tasks, social support from a supervisor, and task variety on emotional exhaustion and innovation based on the categorization approach from the job demands-resources model research...

1,2-Dichloropropane (1,2-DCP) is used widely in Korea as a substitute for trichloroethylene or methylene chloride. Some companies mistakenly consider that 1,2-DCP is an eco-friendly detergent because its use is not regulated, but 1,2-DCP is known to inhibit the central nervous system in animals; a few cases of accidental exposure have been reported in humans. We present a case of acute encephalopathy caused by exposure to 1,2-DCP. A 41-year-old male presented with dizziness, headache, and diplopia after exposure to the detergent without protective equipment...

In 2012, there were about 2.3 million deaths worldwide attributed to work. The highest workplace fatality rate (WFR) was reported on construction sites due to high risk activities. Globally, fall from height is the leading cause of fatal injuries for construction workers. The objectives are to determine Brunei Darussalam's demographic distribution of occupational fatality; identify common causal agents and industry where occupational fatalities commonly occur; and determine WFR by year. This cross-sectional study retrospectively reviewed records of occupational fatality which were notified to the Occupational Health Division, Ministry of Health, from January 2012 until December 2016...

Shift workers are at risk for developing serious health issues due to short sleep. One cause of short sleep is circadian misalignment: sleep time is not synchronized with the body's natural circadian rhythms. Although circadian rhythms are strongly driven by the light/dark cycle, humans have individualized sleep time preferences (chronotypes) based on genetics, development, and external influences. Evening chronotype individuals fall asleep later than average and have a higher risk for developing various noncommunicable diseases...
