Abstract [en]

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

Abstract [en]

Both physical conditions and psychosocial factors at the workplace are implicated in the origin of musculoskeletal disorders (MSDs); however, the evidence is stronger for physical conditions. Some epidemiologic studies have shown a relationship between exposure to cold and the development of musculoskeletal disorders, especially for neck and upper extremity. In order to compare the prevalence of musculoskeletal symptoms between cold-exposed and non-cold exposed workers, a cross-sectional epidemiologic study was performed. The Standardized Nordic Questionnaire was administered to all workers in the packing areas (162) in a large meat processing company in Colombia. The workers were divided in two groups: exposed (50 workers) working in very cold areas (+ 2oC), and less exposed (112 workers) working in less severe conditions (+ 9.4oC). The results show a high prevalence of musculoskeletal symptoms among cold- exposed workers, especially for low back, neck and shoulders (48%, 36% and 24%). The estimated relative risks for neck and low back were 11.2 (95% CI 1.34 - 93.41) and 4.48 (95% CI 1.61 - 12.42), respectively. The authors conclude that these strong associations between cold exposure and musculoskeletal disorders are plausible but the mechanisms remain largely obscure and require further research, both experimental and epidemiologic.

Abstract [en]

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.

Abstract [en]

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.

Abstract [en]

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, both 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.

Abstract [en]

A cross-sectional epidemiologic study was carried out to explore the relationship between musculoskeletal symptoms and cold exposure in a large meat processing company in Colombia. All workers in the packing areas (n=162) were recruited: 50 workers from very cold areas (+2°C) and 112 workers from less severely exposed areas (range +8°C to +12°C). Thermal environmental conditions were measured in both areas. By Standardized Nordic Questionnaire, there was a high prevalence of musculoskeletal symptoms among the more exposed workers, especially for low back, neck and shoulders. The prevalence ratios for neck and low back symptoms interfering with usual work were 11.2 (95% CI 1.3–93.4) and 4.5 (95% CI 1.6–12.4), respectively. Job features that could not be addressed in this study included work shift (day versus night), adequacy of thermal protective clothing, type of contract with the company and psychosocial conditions at work. The association between cold exposure and musculoskeletal problems is plausible but the mechanism is still obscure and there is a need for further research, both experimental and epidemiologic (preferably cohort studies).
