| 总结: | The purpose of this research is to study the impact of workload and work-rest on the mental fatigue since the cognitive work such as inspection, welding and many more where it required very attention visual and induced the mental fatigue. This research was conducted through the design of experiment with the two levels and two factors and 7 workers in welding activity were involved in this experiment. Time reaction has being used as response variable in the experiment and the data were analyzed with Two-way ANOVA to identify the significant impact of the factors on the mental fatigue as well as the significant interaction from that both factors. The best setting for positive impact on mental fatigue was developed through the interaction plot. Paired T-test and regression test also has been used in this experiment for verification and validation. Two-way ANOVA test has been showed that both factor workload and work-rest gave significant impact to the mental fatigue and this both factor also have a strong relationship and interaction that can influencing the level of mental fatigue. The interaction plot also showed that the best setting to reduce the level of mental fatigue is with the run order from light workload versus short and frequent work-rest. The result from the verification and validation proved that this experiment was valid and can be used for future research. |
