“…We have a long tradition in the measurement of forces and the development of methods for the evaluation of physical workload (Schaub, 1996;Schaub, Berg, & Wakula, 1997b;Schaub, Boocock, Greve, Kapitaniak, & Ringelberg, 1996;Schaub, Landau, et al, 1997). We have contributed to the development of the German force standard DIN 33411.…”

“…The physiology factor is a new aspect in evaluating force exertions in industrial applications. Industrial applications include on the one hand a series of force exertions in awkward postures (Schaub, Berg, et al, 1997a, 1997b or single force exertions that necessitate entering an awkward posture. This increased physical effort should be considered.…”

Even in hi-tech industries, physical workload is partly considerable and cannot be avoided because of product and process requirements. Especially in automotive, aviation, and marine industries, the assembly of the product geometry requires force exertions in ergonomically unfavorable conditions. Unfortunately, internationally accepted methods for the evaluation of those types of force exertions are rare. Besides some traditional German methods and EN 1005-3 hardly any evaluation methods exist. Even those methods refer to force exertions in primarily upright symmetric working postures. To overcome these problems the Assembly Specific Fore Atlas was created during the recent years. From a sample of automotive workers (n = 273), a set of 54 whole-body forces (6 main force directions while standing, sitting, kneeling; in an upward, bent, and overhead posture) and a set of 38 types of finger-hand forces (all at maximum voluntary contractions [MVC] levels) were measured in the field. The inputs for the types of force exertions required in practice were sampled from a consortium of major European car and truck companies. In addition, evaluation methods were developed that allow "calculating" maximum recommended force limits from the measured maximum static forces (i.e., MVC) and task and user group relevant parameters. This contribution gives a short overview on the data collected and focuses on the evaluation methods that had been realized. First, qualitative results are presented from the first field tests.

“…Much of this research has been concerned with work-related factors that might adversely affect the flight attendants’ health. Among the factors investigated are circadian dysrhythmia, recycled air, fatigue, shifting work schedules, radiation exposure, and the lifting and handling of heavy objects (Ballard, Lagorio, De Angelis, & Verdecchia, 2000; Dresel & Boutros, 2001; Griffiths & Powell, 2012; Lauria, Ballard, Caldora, Mazzani, & Verdecchia, 2006; Schaub et al, 2007; Sharam, 2007; Suvanto, Partinen, Harma, & Ilmarinen, 1990). Other research has examined how aspects of the job—extended time away from home, irregular work schedules, long hours, and difficult passengers— contribute to work-related stress, psychological well-being, and job dissatisfaction (Avers, King, Nesthus, Thomas, & Banks, 2009; Avers et al, 2011; Gunnarsdottir, Sveinsdottir, Bernburg, Fridriksdottir, & Tomasson, 2006; Liang & Hsieh, 2005; Salinger, Jesilow, Pontell, & Geis, 1985).…”

After 9/11, new security duties were instituted at many U.S. air carriers and existing safety and security duties received increased emphasis. Concurrently, in-flight services were changed and in many cases, cabin crews were reduced. This article examines the post-9/11 conflict between passenger service and the timely performance of safety and security duties at 1 major U.S. air carrier. In-flight data were obtained on both international and domestic flights. The data suggest that the prompt performance of the safety and security duties is adversely affected by the number of service duties occurring in the later part of both international and domestic flights.

Objectives: This study investigated the prevalence of musculoskeletal discomfort among female cabin crew through cabin tasks and demographic factors, including age and seniority. Methods:This study conducted an online questionnaire survey targeted at female cabin crew in Taiwan and ensured that the sample size was with a statistical power of 0.95. This study evaluated the work intensity by ranking six common cabin tasks and examined musculoskeletal discomfort with Cornell Musculoskeletal Discomfort Questionnaire. Descriptive statistics were used to learn the work intensity and discomfort conditions. In addition, the Chi-square test of independence and multivariate adjustment were applied to clarify the impact of age and occupation on musculoskeletal discomfort in the neck, shoulders, and lower back.Results: This study enrolled 88 female cabin crew members. Handling carryon baggage was voted as the highest intensity cabin task (40%), which was also ranked as the strongest intensity on shoulders. Meanwhile, the upper trunk was more prevalent in musculoskeletal discomfort. Moreover, after multivariate adjustment with controlling the effect of age, this study found a marginal significant association (p = .09) between seniority and right shoulder discomfort for younger staff. Conclusion:This study found that handling carry-on baggage was associated with musculoskeletal complaints in the shoulders. Therefore, this study suggested that shoulders, especially for the right side might be related to the occupational injury, which was prevalent along with seniority among the younger crew.Overall, this study provided the preliminary findings to improve occupational training for preventive health.
