title: Ergonomic analysis of the working post of gutter in the fish processing plant and the dependency between subjective evaluation of the work fatigue and the body posture assumed while working.
abstract: The main goal of the present paper was an ergonomic analysis of the working post of the gutters employed in the Fish Processing Plant in Gdańsk and to find the relation between the ailments manifest in the musculo-skeletal system, the degree of the weariness with the work and the body posture assumed during the operations after the first and the sixth hour of the work. The material investigated comprised 20 gutters aged 30-49 years, their employment period on given working post ranging from 11 to 16 years. On the basis of the observation and time analysis of each operation an ergonomic analysis of their working posts was accomplished. Apart from this the subjects were submitted to a questionaire concerning subjective evaluation of the factors affecting fatigue as well as the degree of several body parts load. Shutter method was employed in the cinematographic analysis of the simple flat images. When the contours of a woman were drawn in schemes the following angles could be plotted: angles of the forward inclination of the trunk and the head, angle of the left hand. The pictures were taken in two series: after the first and the sixth hour of the work. On the basis of these investigations no statistically significant differences in the angle of the forward inclination of the trunk and the head after the first and the sixth hour of work were revealed. It indicate the other reasons than a body posture as decisive in the origin of the fatigue with work.(ABSTRACT TRUNCATED AT 250 WORDS)
