Machine timber harvesting makes it possible to reduce substantially factors which have adverse impact on human health and which accompany manual-machine timber harvesting, presently predominating in Poland. The ergonomic factors classified into four following groups may be recognised as the main preconditions related to work with multi-operation machines: physical load – small energy expenditure, a very high value of repetitiveness and static efforts; mental load – high level of monotony, aesthenopia, a high level of stress; environmental load – significant limitation of hazard to operator’s hearing, work under conditions of thermal comfort, reduced vibration hazard; organisational load – a relatively low risk of work – related accidents, making it possible to perform work operations throughout the year, continued employment, high work autonomy, independence in decision making, a possibility for workers to organise themselves and form work teams. The paper presents subjective perceptions and opinions of fifty operators of specialised machines with respect to their work load. Almost a half of the respondents worked over 50 hours per week. One third found their work conditions difficult. Work pace was recognised as particularly challenging to their well-being as merely 6% of respondents found it relatively low. Additionally, the selected elements of assessment of workstations under study in terms of energetic costs and noise load is discussed The maximum energy expenditure of a machine operator is related to operations performed outside a cab: tuning up, routine maintenance, and repairs. Energy expenditure related to work inside a cab did not exceed 14 kJ/min. Noise level in a low-noise cabin was lower than sixty dB(A). Use of machines to a large degree eliminates important health-adverse factors accompanying combined machine-driven and manual timber harvesting, however, it creates conditions favouring occurrence of new ailments and diseases, totally different from those which have been recorded so far in forestry.

Both linear and aerial elements of forest recreational management should be equipped with recreational facilities which are called “small architecture”. Small architecture is very diverse and serves many different functions, thus it is very important in recreation space. Recreation facilities have to be safe for potential users and offer comfort and relaxation. These conditions can be fulfilled if the construction of facilities is based on anthropometric features of the users. In this paper, there are presented the results of analyses carried out with regard to adaptating technical parameters of selected forest facilities to potential user anthropometry. The study was conducted in Warsaw municipal forests. The analyses were based on analytical formulas, which give appropriate information about the parameters of perfectly designed facilities. Examination of technical condition of the recreation facilities analyzed was also included in the study.

While planning, and/or improving the existing workplace it is necessary to utilise the optimal dimensions and arrangement of the workplace, organisation of work-movements and the physical and mental needs of the man as well. The contribution introduces a simple process that is possible to use while planning or rationalizing the workplace. The process is plan is such way to respect the basic ergonomic principles.

Thermal comfort study of plastics manufacturing industry in converting process. Thermal comfort is one of ergonomics factors that can create a significant impact to workers performance. For a better thermal comfort, several environment factors (air temperature, wind speed and relative humidity) should be considered in this research. The object of the study is a building for converting process of plastics manufacturing industry located in Malang, Indonesia. The maximum air temperature inside the building can reach as high as 36°C. The result of this study shows that heat stress is dominantly caused by heat source from machine and wall building. The computational fluid dynamics (CFD) simulation is used to show the air characteristic through inside the building. By using the CFD simulation, some scenarios of solution are successfully presented. Employees thermal comfort was investigated based on predicted mean vote model (PMV) and predicted percentage of dissatisfied model (PPD). Existing condition gives PMV in range from 1.83 to 2.82 and PPD in range from 68.9 to 98%. Meanwhile, modification of ventilation and replacing ceiling material from clear glass into reflective clear glass gave significant impact to reduce PMV into range from 1.63 to 2.18 and PPD into range from 58.2 to 84.2%. In sort, new design converting building process has more comfortable for workers.

Background. Medical professionals frequently experience low back pain as a result of mechanical overload caused by prolonged standing, performing activities in a position of trunk flexion, extended work hours and physically stressful duties. The above-mentioned stresses, when they exceed the adaptive capacity of the tissues, can lead to pain, degenerative changes and even disability. Material and methods. 114 employees, including 48 (42%) physicians and 66 (58%) nurses, were examined. Their average age was 42.08±9.43 years, and the average years of work experience was 17.16±10.36 years. To assess the occurrence of low back pain, a standardized Oswestry Questionnaire was used, while for assessments of ergonomics an original questionnaire was used. Results. 95 respondents (83.33%), including 31 physicians (64.58%) and 64 nurses (96.96%), did not apply the principles of ergonomics in the work environment. The most common reasons were that working conditions were not conducive to ergonomic approaches to their duties and that there were not enough medical personnel to make ergonomic choices possible. All subjects experienced back pain. The Oswestry Questionnaire was used to determine the degree of disability caused by back pain. Among the physicians, the majority of respondents (n=35, 73%) experienced a small degree of disability, while the nurses experienced a moderate amount of disability (n= 35, 53%). Conclusions. Most of the examined personnel did not apply principles of ergonomics and had incomplete knowledge in this area. All subjects were burdened with low back pain, one of every ten of them were seriously affected. The results indicate the need to provide ergonomics education to medical personnel.

When reviewing the work demand factor on human it is necessary to consider the analyses of requirements on locomotive organs, mental processes and also requirements on human sensual functions. The document points out possibilities of usage selected methods of work activity studies in particular conditions. It shows that by realizing precautions, which are a result of the workload analysis it is possible to achieve workload decrease and also work productivity increase.
