Ergonomics
Objectives
At the end of the semester, students must be able to:
- design work systems taking into account the persons'''' physical-motor characteristics and limitations
- evaluate postures
- design workstations based on anthropometric criteria
- design/adapt activities to prevent fatigue (static and dynamic)
- organize workplaces to prevent fatigue and musculoskeletal disorders
- communicate with company safety specialists

Teaching method
Um the classes, the contents are presented to the students using the data show and the blackboard. The students are encouraged to intervene and interact with the lecturer, with a view to assessing their knowledge on human factors and interrelated matters. Um addiction, exercises and examples are discussed in order to consolidate, simulate or train the main topics.
Evaluation method
The final grade is calculated using the following criteria:
• 65% 1 individual test or final exam. The rating must be higher than 9,5.
• 35% of practical work. Delivery of one group work (with three milestones). The grade must be higher than 9,5.
Students must attend 2/3 of the classes.
