A decrease in the working-age population in aging societies causes a shortage of employees in workplaces due to long-term care (LTC) leave for family and relatives as well as longer working hours or overwork among those remaining in the workplace. We collected and analyzed literature and guidelines regarding social-support policies on LTC in workplaces in seven countries (Canada, France, Germany, Japan, Sweden, the UK, and the USA) to propose an effective way of occupational health support for those in need. Our analysis indicated the existence of a system that incorporates the public-assistance mechanism of providing unused paid leave to those in need.

There are several known risk factors for overeating, including negative feelings and hunger. It was hypothesized that overtime work is associated with stress responses and later dinner times, leading to longer periods of time without eating, and that this, in turn, leads to a strong experience of hunger and consequent overeating at dinner. The aim of this study was to examine relationships among overeating at dinner, stress responses (e.

Storage phosphor computed radiography (SR) and flat-panel detector (FPD) radiography are two types of digital X-ray utilizing different techniques. We compared these two techniques with conventional analogue chest radiograph (AR) among pneumoconiotic patients and healthy controls. Thirty individuals consisting of 20 silica-exposed ex-workers and 10 healthy controls without occupational exposure to any mineral dust were examined with chest X-ray by AR, SR and FPD.

Objective: It is important to have data about occupational magnetic field intensity to consider the contribution of occupational magnetic field exposure on the human body. We conducted research on exposure to occupational magnetic fields and tried to qualify data on the distribution of magnetic field' intensity in certain general working environments with individual measurements.

Subjects And Methods: We performed sample research on the exposure to low-frequency magnetic fields of workers in certain occupations and in the working environment.
