The work environment and 20 influencing variables in 20 conventional hospital foodservice systems were examined. Twenty hospitals with more than 500 beds in Seoul were surveyed to obtain data for study variables. The work environment index was measured by five objective measurements including noise (dB), light(Lux), temperature ($^{circ}C$), humidity (％) and ventilation (mι/sec). Statistical methods used in this study were descriptive analysis and Pearson product moment correlation analysis. The number of beds, space of foodservice system, the proportion of dishwashing area space in foodservice system area, noise, humidity, and ventilation were significantly correlated to the work environment of the dishwashing area.
