Abstract:

The research focuses on analysis of ergonomics risks among construction workers in different operations at work. The aim of the research is to carry out ergonomics risk analysis in various construction operations and to prove that physically hard manual work and application of force in manual work operations affect muscular fatigue, using objective and subjective risk assessment methods, including extended version of Nordic musculoskeletal questionnaire, myotonometric measurements, muscle’s force determination with dynamometer. During the research it was proved that the combination of objective and subjective ergonomics risk analysis methods provides holistic approach and reliable ergonomics risk analysis results.

Abstract:

This paper addresses the ability of drivers to intuitively control special passenger car systems that they have as yet not encountered in the course of their driving practice and therefore have no experience of them. The study described in this paper was conducted on a sample group of drivers without any prior experience of the tested model or of any other model of the same brand, and the functions and systems selected for testing were unique for the brand and model in question. The reason for conduction of this study was the endeavour to recreate the common situation in which a driver is forced to drive a car with whose controls he/she has not yet had the opportunity to become acquainted. Based on statistical evaluation of the obtained data, it proved that the initial hypothesis claiming the existence of a correlation between driver parameters such as age, gender or length and quality of driver experience and his/her ability to adapt to completely unknown car control systems could be confirmed. The results in this paper may be applied in the cabin and car control system design process, thereby enhancing the user-friendliness of passenger car controls, thereby also indirectly increasing road traffic safety.

Abstract:

Hotel cleaning work is one of the physically demanding professions. Employees in hotel cleaning processes are subjected to compulsory work postures, frequent body, arm, and leg movements, awkward turns due to areas of restricted spaces or inappropriate work equipment. Such workload can result in health problems and deteriorate health. Therefore, the aim of the research was to determine the physical load for hotel office cleaning staff. 23 hotel cleaners, all female, participated in the investigation participated. For the physical load analysis, a questionnaire, the Key Indicator Method, the quick exposure check method, and heart rate monitoring were chosen. It was proved in this research that the work of hotel office cleaners corresponds to the category of light and moderate workload despite the fact that hotel office cleaners themselves consider the work process to be very intensive and physically demanding. Further studies are necessary in order to clarify the fatigue level and other social risks that can influence the physical workload of employees.

Abstract:

Abstract. The  computer  based  e-learning  in  Moodle  environment  and  other  computer applications in the teaching of occupational health and safety (OHS) are investigated. The social constructivist  learning  theory  is  effective  method  for  teaching  and  learning  of  OHS  and ergonomics  issues  in  the  university  education.  The  computer  programme  for  determination  of the  safety  level  at  enterprise  is  presented.  The  simple  computer  applications  are  very  suitable educational  tools  for  e-learning  of  OHS  and  ergonomics.  They  could  be  also  used  by  the employers  of  small  and  medium-sized  enterprises.  The  scope  of  practical  applications  of  e-learning in OHS and ergonomics in higher education is analysed on the basis of the scientific literature and analysing the methods used in the EU.

Abstract:

The research focuses on determination of the workload and work strain in small andmedium-sized metalworking enterprises of Latvia. A number of studies in the world prove thatthe effectiveness of an organisation is closely related to a human, performer of the work, whoseskills and health affect the results of the organisation’s activity. This research, by applyingergonomics load evaluation methods, showed that extensive workload and work strain inmetalworking enterprises has a negative impact on workers’ wellbeing and health. Theeconomics effectiveness calculations confirmed that the investments in ergonomics inmetalworking manufacturing processes maintain human resources and are economicallyfavourable in ensuring enterprise effectiveness, but further studies are necessary to evaluateworkers’ contribution and willingness to participate in ergonomics interventions.
