Tomasz Hermann, Marian Witalis Dobry
The article presents an application of the energy method to assess the energy input introduced into two subsystems of the human-glove-tool system. To achieve this aim, a physical model of the system was developed. It consists of dynamic models of the human body and the glove described in the Standard No. ISO 10068:2012, and a model of a hand-held power tool. The energy input introduced into the subsystems, i.e., the human body and the glove, was analysed in the domain of energy and involved calculating three component energy inputs of forces...

Sitting for long periods of time, both during work and leisure times, is the typical behavior of the modern society. Especially at work, where there is not much flexibility, adopting the sitting posture for the entire day can cause some short- and long-term effects. As workers' productivity and well-being relies on working conditions, evaluating the effects caused by the work postures assumes a very important role. The purpose of this paper was to evaluate the variation of some anthropometric measurement during one typical workday to understand if the known long-term effects, can also be seen and quantified in an 8-hour period...

The main objective of this paper is to determine key factors that may have a significant effect on the verbal abuse, emotional abuse, and physical assault of health care workers in north-eastern Turkey. A self-administered survey was conducted to 450 health care workers in three well-established hospitals in Erzurum, Turkey. Due to the discrete and ordered nature of the dependent variable of the survey, the data were analysed using four distinctive ordered response models. Results revealed that several key variables were found to be a significant determinant of workplace violence such as the type of the health institution, occupational position, weekly working hours, weekly shift hours, the number of daily patient contacts, age group of the respondents, experience in the health sector, training against workplace violence, and the current policies of the hospitals and the Turkish Ministry of Health...

This study aims to define the relationship between risk degrees and risk indexes on different functional structures with the assumption that, risk degrees may not always present linear relationship with the risk indexes. In this wise, risk indexes; suitable for expert evaluation of working conditions and computed by using three different membership functions are determined. Among the membership functions used, one of them is preferred as linear and the others are preferred as nonlinear. Additionally, a new fuzzy risk assessment (RA) algorithm is developed by using these three membership functions...
