Opis:
Work Factor Compatibility (WFC) theory proposes that human performance is dependent on the interaction of various components (e.g., physical and mental task demands, physical environment, social environment) of the work system and integrates multiple human performance perspectives into a single mathematical model. Work Factor Analysis (WFA) is a comprehensive survey administered to employees to determine the WFC index. WFA also provides recommendations for targeting specific work system areas for improvement. Preliminary testing oft he tool was conducted at a manufacturing operation of a Fortune 10 company. Results are discussed and recommendations for further study are made.

Opis:
This study investigated workers’ perceptions of workplace safety in an African work environment, specifically in Ghanaian work places. Workers’ safety perceptions were examined with Hayes et al.’s. (1998) Work Safety Scale. Comparative analyses were done between high- and low-accident groups, and t tests were employed to test for differences of statistical significance. Relative to their colleagues in the low-accident category, workers in the high-accident category exhibited negative perceptions on safety. They had negative perceptions regarding work safety, safety programmes, supervisors, and co-workers’ contributions. Besides, they expressed less job satisfaction and were less committed to safety management policies. Perceptions regarding management’s attitude towards safety between the 2 groups were not of statistical significance. The analyses provided an explanation for the cause of a substantial portion of the high rate of industrial accidents in Ghana’s work environment. Implications for safety management are discussed.

Opis:
A lot of attention has been focused on workers’ perceptions of workplace safety but relatively little or no research has been done on the impact of job satisfaction on safety climate. This study investigated this relationship. It also examined the relationships between job satisfaction and workers’ compliance with safety management policies and accident frequency. A positive association was found between job satisfaction and safety climate. Workers who expressed more satisfaction at their posts had positive perceptions of safety climate. Correspondingly, they were more committed to safety management policies and consequently registered a lower rate of accident involvement. The results were thus consistent with the notion that workers’ positive perceptions of organizational climate influence their perceptions of safety at the workplace. The findings, which have implications in the work environment, are discussed.

Opis:
A participatory ergonomics model was designed for improving working conditions, quality, and productivity in a medium-sized manufacturing enterprise by making use of Supportive Expert Team (SET). In order to implement the model, a team-based structure consisting of a Steering Committee (SC) and 2 Action Groups (AGs) was designed and a 5-phase methodology followed. To validate the model, a similar factory was selected as control. Performance of the model was successful throughout the project. AGs under the supervision of the SC and the support of the SET designed and implemented several ergonomics solutions using local resources. Our findings showed that, in comparison with the control factory, application of such a model could be considered as a provider of a more humanized work environment as well as a more efficient and cost-effective approach.

Opis:
Part of the Polish-Swedish OSHMAN project was carried out in a textile company. It aimed at implementing and improving effective health and safety management with workers’ active involvement at all levels of the enterprise. The two main problems to be solved during the project were decreasing occupational risk and improving workers’ poor knowledge on occupational risk. Training courses, workshops and practical activities were undertaken. As expected, there were changes in work organisation and improvement in the way workstations were looked after, which led to a decrease in occupational risk. Workers were highly committed during the project. Nevertheless it seems that more training should be directed at middle management.

Opis:
Crews on tankers traveling and hauling cargo on the lower reaches of the Mississippi River during the hot and humid (H&H) summer season face various occupational safety and ergonomics problems. Evaluation of medical data reveals that a large number of the crewmembers experience job related injuries, diseases, disorders, and exhaustion as a result of adverse environmental conditions (National Institute for Occupational Safety and Health [NIOSH], 1993). The accidents and injuries that occurred were characterized and then analysis was used to recommend constructive remedies and solutions. The results were also used to design and develop better work environments on the tankers and in the general industry. In H&H conditions, the body’s chemical reactions constantly change in order to maintain the best possible reaction to changing environments. This chemical reaction increases blood flow to the skin through sweating. Body metabolism stabilizes body temperature through muscular work and convection, evaporation and radiation remove heat.

Opis:
An organizational change among 82 postal workers was studied with the aim of evaluating the effects on the work environment, work ability, and musculoskeletal complaints. The study was undertaken in 2 suburbs of Stockholm, Sweden. Psychological work demands were estimated to be reduced at the 1-year follow-up but physical work demands had changed very little. In an observation study in a subgroup of older workers, the risk of overexertion at work and musculoskeletal complaints was reduced. In spite of that, most of the older participants (>35 years) had unchanged or increased musculoskeletal symptoms. This shows the need for early preventive measures.

Opis:
The present study was conducted to analyze the ratification status of International Labour Organization (ILO) conventions related to occupational safety and health (OSH) by ILO member states in terms of national indicators (length of ILO membership and national income status) and regional affiliation. 17 conventions designated as OSH-related by the 2003 International Labour Conference were examined. In general, countries with longer ILO membership ratified higher numbers of conventions related to OSH. With some variation, long-membership countries had the largest number of ratifications, followed by middle- and shortmembership countries in all regions. There were also incremental increases in the number of ratifications for OSH-related conventions according to the national income status. Common regional characteristics that could not be explained by the factors studied also existed. Future efforts to increase ratification at an international level will need to consider the factors influencing ratification practice among the member states.

Opis:
The study deals with working conditions in small private enterprises in Poland. Data come from 50 small enterprises from the Warsaw area. Information about the evaluation of working conditions and the existence of programmes for their improvement was gathered with the help of questionnaires addressed to employees and employers. The results constitute a “photograph” of the Polish reality at the beginning of its transition from planned to market economy. The study revealed a lack of programmes for the improvement of working conditions in a significant number of the enterprises studied as well as little interest in occupational safety on the part of employers (owners). The study also revealed that all decisions—including those about the improvement of working conditions—were made by employers. Hence, the need for the widest possible dissemination of knowledge on occupational safety and the protection of human in the working environment with particular stress put on employers. Employers who are knowledgeable in this field and who are aware of its importance can significantly influence the improvement of working conditions in small enterprises.

Opis:
The purpose of this study was to determine if the advantages and disadvantages of a new automotive seating concept, known as the micro-adjuster control system, could be reliably evaluated using both a physiological assessment technique (i.e., electromyography [EMG]) and a subjective questionnaire. The results indicate that psychophysical measures of discomfort and the root mean squared (RMS) activity of the EMG are statistically related, r (8) =–.788, p=.020. More specifically, subjective perceptions of comfort were found to improve with decreasing levels of muscle activity. This implies that seat comfort can be evaluated on the basis of physiological as well as subjective responses to prolonged driving. This finding should drastically improve automobile seat design efforts.

Opis:
Proprioceptive derivation (Pd), a new method of organising a dentist workstation as well as a working procedure, was introduced to Thailand. The aim of this study was to assess the working conditions and the attitude to Pd among experienced users. Questionnaires were distributed among 12 dentists. The results showed that all dentists chose to work in a sitting posture and mostly worked without breaks between patients. They spent less time on dental examination and crown and bridge therapy tasks. Solving problems in patients with physical limitations resulted in a low stress level. Seven dentists (58.3%) always used Pd and liked it. Five dentists (41.7%) sometimes used Pd, with 3 of them liking it. Only 2 dentists, who sometimes used Pd, did not like it because it could not cover all dental tasks and treatment, and it was difficult and complex.

Opis:
The main objective of this study was to evaluate different scales of perceived strain during the performance of various physical tasks. A total of 52 male and female participants took part in 4 experiments to achieve the study objective. The results suggest that a bipolar comfort-discomfort scale is a more appropriate instrument than a discomfort scale for assessing cumulative physical stresses at work, especially at the beginning of the shift. For assessing discomfort at the end of the work shift, a unipolar scale may also be used. On the basis of the obtained results, red, green, and yellow zones are suggested to establish priorities for work redesign efforts in ergonomic control programs.

Opis:
One hundred and sixty-nine bank employees were investigated with the Orientation to Work Values Inventory by Seifert and Bergmann (values; Seifert & Bergmann, 1983), and the Work Description Inventory by Neuberger and Allerbeck (importance and satisfaction with work aspects, overall job satisfaction; Neuberger & Allerbeck, 1978). The data show complex connections between values and the perceived importance of work aspects and job satisfaction. The results indicate that (a) the importance of achievement and social relations values influences the importance of aspects of work, (b) overall job satisfaction depends on social relations value and satisfaction with some aspects depends on this value or on interactions of both of the values, (c) predicting overall job satisfaction from satisfaction with aspects of work is modified by the interaction of the values. However, the hypothesis that overall job satisfaction can be predicted from satisfaction with most important aspects of work is not confirmed by the data.

Opis:
Relationships between employment type and the physical work environment were studied among blue-collar workers (n = 1,127). Based on survey data, we set out to compare the evaluations of environmental load and physical strain at work given by fixed-term (17% of all) and permanent workers. The type of employment was not related to environmental load. However, working on a fixed-term basis increased the risk of physical strain at work. Analyses revealed that this connection was evident only among fixed-term construction workers. The results did not support the much-cited view that the disintegration of standard employment has given rise to a new series of work environment problems. Such problems are concentrated in an area with a long tradition of work environment problems, that is, in the construction industry.

Emotions are an increasingly important factor in Human-Computer Interaction (HCI). Up to the present, emotion recognition in HCI implies the use of explicit or intrusive methods, for example, video cameras or physiological measurements. We are developing and evaluating a method for the measurement of affective states through motor-behavioral parameters from standard input devices (mouse and keyboard).
