Opis:: This paper presents 2 musculoskeletal disorders questionnaire surveys in 10 different Chinese occupational groups. Data collected from 1,603 workers using a modified Nordic musculoskeletal disorders symptom questionnaire showed that the 12-month prevalence of musculoskeletal disorders, particularly in the low back and shoulder-neck regions, was high at many Chinese workplaces. Significant differences existed between occupational groups. Assembly workers usually had higher neck-shoulder complaints compared to workers in most other occupations. However, the nature of assembly seemed also to influence the prevalence rate. Workers at a cassette recorder and a TV set assembly plant appeared to have more neck complaints compared with a group of thermos flask assemblers.

Opis:: This paper reviews the role and importance of small-scale industries together with the issue of occupational health problems and their causes in Iranian hand-woven carpet industry as a typical informal small-scale industry in an industrially developing country. The objective of this paper is to review health risk factors and related occupational health and ergonomic problems in the carpet industry. Since the overwhelming majority of weavers. health problems originate from ergonomic risk factors, it is concluded that any improvement program in this industry should focus on ergonomic aspects. To assess ergonomic conditions in weaving workshops, a checklist has been developed and an ergonomics index indicating the ergonomic conditions of the workshop has been proposed. To test and verify the checklist, 50 weaving workshops were visited and their ergonomic conditions were assessed. Based on the results some modifications were made and the checklist was shown to be an effective tool.

Opis:: Carpet weaving is a high risk occupation for developing musculoskeletal disorders (MSDs). The objectives of the present study, which was carried out in the Iranian hand-woven carpet industry, were determination of the prevalence of MSD symptoms, identification of major factors associated with MSD symptoms and development of guidelines for workstation design. 1,439 randomly selected weavers participated in this study. A questionnaire was used to collect data on MSD symptoms. The results revealed that the prevalence rates for symptoms in different body regions were high as compared to the general Iranian population (for neck, back and large joints, p < .0001). The results of multivariate analyses showed that major ergonomic factors associated with musculoskeletal symptoms were loom type, working posture, daily working time and seat type. Based on the results, some general guidelines for designing weaving workstations were developed. A prototype test showed that the new workstation was acceptable for subject tests and that it improved working posture.

Opis:: Carpet weavers suffer from musculoskeletal problems mainly attributed to poor working postures. Their posture is mostly constrained by the design of workstations. This study was conducted to investigate the effects of 2 design parameters (weaving height and seat type) on postural variables and subjective experience, and to develop guidelines for workstation adjustments. At an experimental workstation, 30 professional weavers worked in 9 different conditions. Working posture and weavers’ perceptions were measured. It was shown that head, neck and shoulder postures were influenced by weaving height. Both design parameters influenced trunk and elbows postures. The determinant factor for weavers’ perception on the neck, shoulders and elbows was found to be weaving height, and on the back and knees it was seat type. Based on the results, the following guidelines were developed: (a) weaving height should be adjusted to 20 cm above elbow height; (b) a 10º forward-sloping high seat is to be used at weaving workstations.

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:: In industrially developing countries, a few ergonomists have directed great efforts towards developing ergonomics awareness among managers and workers in organizations. There is little research on the degree of their success, though. Furthermore, access of organizations to ergonomics knowledge is usually very difficult, especially in industrially developing countries. Thus, building ergonomics awareness is certainly the first phase of the process. Three companies from one industry (44 people: 14 females and 30 males) participated in a project aimed at improving their work system. At the beginning, we needed to create a common goal and ensure participation with appropriate ergonomics tools. The findings of this study were the key issue for the ergonomics intervention (i.e., a shared vision, awakened need of change and learning). Further, to build ergonomics awareness and develop a continuous learning process in the company, it was necessary to use more ergonomics tools through workers’ participation in different workplaces.

Opis:: The irritation potencies of 8 dental polymer products, used as dental restorative materials, adhesives, or temporary constructions, were tested using the HET-CAM (hen's egg test-chorioallantoic membrane) technique. Liquid and powder components, and extracts of cured and freshly mixed non-cured materials of 5 glass ionomers, 1 bonding, 1 composite, and 1 cold-cured acrylate were examined. Results showed that the liquid component of all products had a strong irritation capacity but powder suspensions and extracts from cured and freshly mixed non-cured materials had no effect on the CAM. Thus, dental personnel who handle liquid and powder manually are exposed to components with a high irritation potential, in contrast to patients who are exposed to the cured and mixed non-cured materials with low irritation potential. This illustrates the importance of safe handling procedures and practices for dental personnel who handle non-cured polymers manually.

Opis:: Dental personnel are at risk as they manually handle polymer products containing monomers and additives that cause irritation and induce allergy. Gloves and face masks can be easily penetrated by monomers. A total of 587 dental personnel and a referent group (585) in the 2 most northern regions of Sweden were included in a questionnaire study (response rate 76%). Questions were asked regarding symptoms of atopy, asthma, conjunctivitis, atopic dermatitis, hand dermatitis, and hay fever/rhinitis. The dental personnel were asked to give the name of polymer products used in their practice and the frequency of use. They were also asked to risk evaluate 5 different types of polymer materials on a scale from 1 to 5. Analysis was done to find if the occurrence of a symptom was associated with a high risk evaluation of a polymer material, or with frequent use of a certain polymer product. Significantly more dentists reported symptoms of atopic dermatitis and conjunctivitis compared to referents and chair assistants. Results show that dental personnel with symptoms risk evaluated most materials significantly higher than dental personnel without symptoms. Further, the occurrence of some symptoms was associated with frequent use of 8 polymer products.

Opis:: Eye infections are common among dentists and many are concerned, but few are using proper eye protection. To understand users’ demands behind the low use of safety glasses, all dental teams in Sweden were asked which factors they found most important when choosing dental safety glasses, and rate the importance of 31 statements regarding ergonomic aspects of dental safety glasses in a questionnaire. Data were analysed using the Grounded Theory and a quantitative approach. Results showed that dentists ranked the visual aspects as most important and chair assistants the protective aspects. The highly visual demanding work performed by dentists requires safety glasses that are not yet available on the market, which might explain the low use.

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:: This study was carried out to assess Future Workshop (FW) regarding its usefulness as a participatory ergonomics method, using a descriptive evaluation design analysed by phenomenographical approach. The study was conducted among professional cleaners, health care personnel and miners, with a sample of 105 participating subjects in 8 different FWs. Multiple methods, giving a combination of both qualitative and quantitative data, were used for data collection. Good involvement of participants was observed during workshops. Evaluations immediately after FWs and 3 months later showed a strong relationship with high correlation, indicating that the perception of FW participants was very positive. Interviews revealed conformity between developed problem identification and proposed changes. Participants’ own perceptions of FW’s influence on creativity depict their belief of developed ideas and solutions in order to identify and solve workplace problems. FW is considered to be a useful ergonomics tool, and its qualities are related to structure and practical performance.
