초록

Protected horticulture is labor-intensive. It necessitates great amount of labor in many tasks including grafting, pollination and harvesting. Particularly, carrying crops involves the most intensive labor which leads to a high risk of musculoskeletal disorder. Thus, this study aims at developing an ergonomic vehicle to reduce this intensity of labor and ergonomic evaluation by applying the newly developed vehicles to REBA. 5 healthy male subjects with no records of any musculoskeletal disorder were participated in this study. The experimental units were divided into three categories: lifting, lowering and pushing tasks. The results showed that the developed vehicle received less loads in group B (arms and wrists) than in group A (trunk, neck and legs). Especially, the developed vehicle scored $1.0{\sim}4.4$ in group C on REBA while the conventional wheelbarrow got $3.0{\sim}7.6$, regardless of working postures. In conclusion, the developed ergonomic vehicle provided less loads for human bodies compared to the conventional one.
