Little concern has been given so far to the latter group of factors by occupational health services in their diagnostic and preventive activities. That resulted from a specific character of psycho-social stimuli and their direct effect on workers' health disorders. A large multitude and variety of psycho-social hazards, a growing exposure to these hazards and health effects induced by them together with economic consequences call for much more attention to be paid to these factors. It will not be an easy task and that is why the authors speak about a challenge to occupational health services.

The authors present a model of such a system, its objectives and conditions which should be satisfied in order to put the system into operation. The model discussed is somewhat an ideal solution which does not necessarily adhere to the reality but it sets tasks and identifies lines of activities to be carried out at the Department of Occupational Psychology, the Nofer Institute of Occupational Medicine, Lodz. These activities are aimed at monitoring and evaluating of health risk generated by psycho-social factors.

These effects manifest themselves in intellectual function disorders. The aim of the present study was to answer the following questions: a) does the whole period of exposure to CS2 seriously affect a decrease in intellectual efficiency level, b) what is the dynamics of these changes in relation to the exposure duration? For the purpose of a study which included 120 employees of plants producing artificial fibres who were exposed to CS2 for a long time the following techniques were used: Wechsler's Intelligence Scale for Adults, A. L. Benton's Visual Memory Test, T.;. Graham and B. S. Kendall's Memory-for-Design Test and L. Bender's Visual Motor Gestalt Test. The results obtained indicate that: a) rate of decrease in intellectual functions level depends on exposure duration and concerns those workers who had been exposed to CS2 for about 30 years; b) serious disorders are observed in such skills as: acoustic and visual memory, symbolic thinking, ability to plan and anticipate events, graphomotoric functions and mental work rate.

A questionnaire was applied as a main tool of the study. The aim of the study was subjective annoyance rating of low frequency noise at workplaces on a 100-degree rating scale. Using the same scale, the study subjects rated annoyance of reference wide-band noise (60 +/- 2, 70 +/- 2, 75 +/- 2 and 80 +/- 2 dB(A)) and reference low frequency noise (65 +/- 2, 70 +/- 2, 75 +/- 2 and 80 +/- 2 dB(A)) reproduced by phones. Questionnaire inquires were preceded by the measurements of A-, C- and G-weighted equivalent continuous sound pressure levels (LA eq.T, LC eq,T i LG eq,T). Noise with prominent low frequency components (10-250 Hz) at A-weighted sound pressure level of 47.7-65.2 dB was assessed as more than somewhat annoying (more than 25 degrees on the 100-degree annoyance rating scale) by 70% of workers examined. No correlation between subjective annoyance rating of the noise at the workplaces and LA eq,T or LG eq,T was noted. Statistically significant correlation (r = 0.23) between subjective annoyance rating and LC eq,T was observed. The subjective rating of annoyance of the reproduced low frequency noise and wide-band noise differed significantly. Low frequency noise was rated as more annoying than wide-band noise at the same A-weighted sound pressure levels.

The aim of the study was to compare the degree of annoyance caused by LFN with that caused by broadband noise (BBN) without dominant low frequency components at similar A-weighted sound pressure levels. Materials and Methods: Subjects included in the study were 145 male employees of the control rooms. They were exposed to noise through headphones at gradually increasing dB A-weighted sound pressure levels within the range of 62-84 dB. Annoyance rating was based on a 100-score graphical scale. Results: LFN was rated as significantly more annoying than BBN at the comparable A-weighted sound pressure levels. The annoyance assessment of either noise did not depend on age, length of employment or the level of exposure to noise at a current workplace. Conclusions: LFN represents a higher risk of influencing human well-being than regular BBN and should be considered in the occupational exposure assessment.

The aim of the study was to investigate whether exposure to LFN at levels normally occurring in the industrial control rooms can influence human mental performance (e.g., visual functions, concentration, continuous and selective attention) and subjective well-being. Materials and Methods: The study included 96 female and male volunteers, aged 19-27 years, categorized in terms of sensitivity to LFN. They worked with four standardized psychological tests (Signal Detection, Stroop Color-Word, Comparing of Names, and Continuous Attention) during exposure to LFN or broadband noise without dominant low frequency content (reference noise) at a level of 50 dB(A). Each subject was studied only once at randomly-assigned exposure conditions. Results: In the Comparing of Names Test, the subjects, regardless of the LFN sensitivity, showed tendency to make more errors during exposure to LFN than in the reference noise, and in the Signal Detection Test, they generally reacted faster (had shorter median detection time). In those noise conditions, however, the high-sensitive to LFN subjects, showed tendency to work less precisely (achieved lower number of correct responses in the Signal Detection Test) compared with the low-sensitive ones, while in the reference noise there was no difference related to noise sensitivity. The subjects categorized as high-sensitive to LFN also showed poorer performance than others during exposure to LFN in the Stroop Color-Word Test (a significant interaction between noise and noise sensitivity in case of reading interference index) and in the Continuous Attention Test (a tendency to more erroneous reactions). Conclusions: These findings suggest that LFN at moderate levels might adversely affect visual functions, concentration, continuous and selective attention, especially in the high-sensitive to LFN subjects.

Bearing in mind that psychophysical condition changes after such an event, this group of people has to be readapted to work. Factors that determine good work performance among post-infarction workers have been not yet investigated. The aim of our study is to identify those factors and to define their role in the readaptation process. The first stage of our project involved the development of a theoretical model of readaptation to work after myocardial infarction. This model is described in this paper. It comprises the following components: medical evaluation of the workers' health status, his or her subjective assessment of work ability, expectations (optimistic vs. pessimistic attitude), motivation to work, social support, and job characteristics.

The research was based on a sample of 500 social workers. The "Psychosocial Factors" and "Job satisfaction" questionnaires were used to test the hypothesis. The results showed that job satisfaction increased with increasing job accessibility and personal resources (r = 0.44; r = 0.31; p < 0.05). The analysis of variance (ANOVA) indicated that job resources and job demands [F(1.474) = 4.004; F(1.474) = 4.166; p < 0.05] were statistically significant sources of variation in job satisfaction. Moreover, interactions between job demands and job resources [F(3,474) = 2.748; p <0.05], as well as between job demands and personal resources [F(3.474) = 3.021; p <0.05] had a significant impact on job satisfaction.

At the beginning they were used to train pilots, and eventually they were used in the automotive industry for testing the strength of new vehicles and ergonomic solutions. With time research institutions and technical universities from outside the automotive industry have become more and more interested in simulators. Attractiveness of simulators for researchers is based on a number of important factors: they create the possibility of modeling, control and repeatability of different experimental situations, reducing at the same time the impact of confounding factors. Simulators have a great potential for data collection and processing. What's more, they are safe and ecologic. These values make them almost an ideal research tool. The article presents a review of psychological studies with use of vehicle driving simulators. It also points to advantages and disadvantages of these devices and outline...

In Poland, work force participation rate for people aged 54-65 years is particularly low compared to other countries. The aim of the presented study was to explore psychological and socio-demographic factors affecting the early retirement decision. The study was performed on 199 manual and skilled workers aged 50-64 years. The data were obtained by means of: Effort-Reward Imbalance questionnaire, Organizational Commitment Scale and adapted items from Work Description Inventory. To explore the risk factors for an early retirement, the logistic regression was used. The following risk factors of an early retirement were identified: low education (primary and vocational Exp(B) = 10.394, p = 0.001; secondary and Bachelor's degree Exp(B) = 3.462, p = 0.001), low health status (Exp(B) = 3.36, p = 0.006, Exp(B) = 7.73, p = 0.002) and lack of rew...

Therefore, many organizations, established to protect occupational health and safety, include stress-related issues into their preventive activities. This article is the first part of a broader review of approaches to work stress prevention and existing practices in Europe. It presents anti-stress interventions elaborated and implemented at international and national levels, such as: legal and research initiatives, educational actions, supporting the development of knowledge of occupational stress, and promoting the idea of healthy work place.

The present study was undertaken to develop a new instrument for assessing one's adaptation to work and to evaluate the psychometric parameters of the test. A questionnaire called "My work", based on the person-environment fit theory model, has been elaborated. The questionnaire consists of 23 items, describing various aspects of adaptation to work. The results of a survey, performed on 292 individuals, provided the grounds for testing the validation parameters of the questionnaire. The following psychometric properties were assessed: Cronbach's alpha reliability coefficient (0.92), stability (0.75), and content validity. Preliminary normative values for the test were also established. The "My work" test shows a good psychometric characteristic and it can be useful for both research work and practical appli...

The subjects were 186 motor vehicle drivers, aged 26-64 years. The parameters examined included eye-hand coordination and reaction time. The analysis of the results revealed that a significantly decreased level of psychomotor function could be noted at the age of 45 years. It was assumed that the results of psychological tests performed by persons with 0.05% BAC can be the empirical criterion for a decline that would significantly impair the driver's work capability. The findings of our study made it possible to develop a proposal for modifying the testing procedure and the principles of certifying work capability of motor vehicle drivers.

The aim of this study was to assess the influence of LFN on human mental performance. Subjects were 193 male paid volunteers. They performed standardized tests: the Signal Detection Test (test I), the Stroop Color-Word Test (test II), and two sub-tests of the General Aptitude Test Battery, i.e. the Math Reasoning Test (test III) and the Comparing of Names Test (test IV). Three different acoustic conditions were used in the experiment the background laboratory noise of about 30 dB(A), LFN and the broadband noise at comparable db(A) levels of 50 dB. The study subjects were assigned randomly to varied experimental conditions. After the test session, the subjects completed a questionnaire aimed at rating the subjective annoyance of exposure conditions during the tasks, and asse...

Material and Methods: The study group comprised 156 subjects. All subjects were asked to fill in a questionnaire developed to enable evaluation of their living conditions, including prevalence of annoyance due to the noise from wind turbines and the self-assessment of physical health and well-being. In addition, current mental health status of the respondents was assessed using Goldberg General Health Questionnaire GHQ-12. For areas where the respondents lived, A-weighted sound pressure levels (SPLs) were calculated as the sum of the contributions from the wind power plants in the specific area. Results: It has been shown that the wind turbine noise at the calculated A-weigh ted SPL of 30-48 dB was noticed outdoors by 60.3% of the respondents. This noise was perceived as annoying outdoors by 33.3% of the respondents, while indoors by 20.5% of them. The odds ratio of being annoyed outdoors by the wind turbine noise increased along with increasing SPLs (OR = 2.1; 95% CI: 1.22-3.62). The subjects' attitude to wind turbines in general and sensitivity to landscape littering was found to have significant impact on the perceived annoyance. About 63% of variance in outdoors annoyance assessment might be explained by the noise level, general attitude to wind turbines and sensitivity to landscape littering. Conclusions: Before firm conclusions can be drawn further studies are needed, including a larger number of respondents with different living environments (i.e., dissimilar terrain, different urbanization and road traffic intensity).

Najpierw były one stosowane w szkoleniu pilotów, później zaczęto je wykorzystywać w przemyśle samochodowym do badania wytrzymałości nowych pojazdów i rozwiązań ergonomicznych. Z czasem symulatorami zaczęły coraz bardziej interesować się instytucje badawcze i uczelnie techniczne spoza branży motoryzacyjnej. Atrakcyjność symulatorów dla badaczy opiera się na kilku istotnych czynnikach: stwarzają one możliwość modelowania, kontrolowania i powtarzania różnych sytuacji eksperymentalnych, przy jednoczesnym minimalizowaniu czynników zakłócających. Ponadto symulatory dysponują dużym potencjałem gromadzenia i przetwarzania danych. Co więcej, są bezpieczne i ekologiczne. Te zalety sprawiają, że są one niemal idealnym narzędziem badawczym. Artykuł prezentuje przegląd badań z dziedziny psychologii z wykorzystaniem symulatorów jazdy samochodem. Wskazuje także na zalety i wady tych urządzeń oraz perspektywy na przyszłość dla badań eksperymentalnych.
