Abstract

The paper addresses complex evaluation of safety culture in Slovak manufacturing enterprises by utilizing specific determinants. To accommodate conditions of enterprises in Slovakia, a specific research method was developed for the study of safety culture, which can also be used for manufacturing and non-manufacturing enterprises. We have selected the questionnaire method. Due to the scope of the research, we have defined ten determinants, which form the basis for evaluation of safety culture elements. When determining the level of the specific ten determinants of safety culture, we studied interdependence between the enterprise’s industry, its size (small, medium, large) and points assigned to each determinant. The results of the study are evaluated using a 3D point graph. The discussion shows parts that were evaluated the highest or lowest and outlines suggested approaches to improve the current state.

Abstract

The paper deals with increasing processes efficiency at a production line of cylinder heads of engines in a production company operating in the automotive industry. The goal is to achieve improvement and optimization of test processes on a production line. It analyzes options for improving capacity, availability and productivity of processes of an output test by using modern technology available on the market. We have focused on analysis of operation times before and after optimization of test processes at specific production sections. By analyzing measured results we have determined differences in time before and after improvement of the process. We have determined a coefficient of efficiency OEE and by comparing outputs we have confirmed real improvement of the process of the output test of cylinder heads.

Abstract

The article presents the results of research carried out as a part of a project aimed at integrated ergonomic diagnosis of the work environment in terms of improvement of technical and psychosocial conditions. The research carried out so far included small and medium-sized enterprises located in the Śląskie Voivodeship. The tests included blue-collar workers as well as administrative (white-collar) workers. Ergonomic diagnosis was carried out by direct observation of employees at the workplace using tools such as the Ergonomic Control Test CET II and the Dortmund list. This article presents the results of ergonomic analysis at a workstation with a computer.

Abstract

The aim of European Union policy is to implement the principles of sustainable development, in which particularly important are: environmental protection and rational management of resources. Major role is given to waste management and appropriate prioritization of activities in this area. The main goal of waste management is prevention, minimization and elimination of wastes “at source”, as well as encouraging efficient use of natural resources through recovery and recycling of waste. Storage process should be minimalized over the years until the complete elimination. As shown by statistics data, unfortunately in Poland, the process is very slow. The analysis of the data provided by the Central Statistical Office (CSO) over the last thirteen years shows a significant increase in the level of recovery and recycling of municipal waste. All together it was 11.654 million Mg of municipal waste collected in 2016. Wastes selected from municipal waste (paper, glass, plastics, metals) accounted for only 25.2% (2.942 million Mg), and mixed waste accounted for 74.8% (8.712 million Mg). In 2016 the recycling rate was 27.83%, composting or fermentation – 16.22%, 19.44% of municipal wastes are subjected thermal transformation and the storage level is 36.51%. Landfilling is still the most common form of municipal waste disposal.

Abstract

The article focuses on evaluation of human reliability in the human - machine system in the railway industry. Based on a survey of a train dispatcher and of selected activities, we have identified risk factors affecting the dispatcher‘s work and the evaluated risk level of their influence on the reliability and safety of preformed activities. The research took place at the authors‘ work place between 2012-2013. A survey method was used. With its help, authors were able to identify selected work activities of train dispatcher’s risk factors that affect his/her work and the evaluated seriousness of its influence on the reliability and safety of performed activities. Amongst the most important finding fall expressions of unclear and complicated internal regulations and work processes, a feeling of being overworked, fear for one’s safety at small, insufficiently protected stations.
