동시에 발생하는 사무작업 사이의 간섭정도에 관한 연구

To quantify a mental workload for office workers, nine element tasks were classified for office work. There were oral comprehension, written comprehension, oral expression, written expression, calculation, memorization, thinking, and classification materials. Among nine element tasks, oral comprehension, written comprehension, written expression, and thinking were selected and the degrees of conflicts between concurrently performed element tasks were measured and analyzed through the experiment. The measures were performance and subjective rating. The results were as follows. The written comprehension- written expression pair was showed the highest conflict value in terms of performance and subjective rating. The written comprehension-thinking pair was the lowest conflict value in terms of performance, while the oral comprehension-thinking pair was the lowest condlict value in terms of performance, while the oral comprehension- written expression pair was the lowest conflict value in terms of subjective rating. The findings are expected to be used for assessing workload for the office work.
