주방작업대 높이에 대한 실태조사

Abstract

This study was conducted to evaluate the appropriateness of the heights of the kitchen tables installed in some houses including apartments, villa and individual houses. Heights of the kitchen tables were measured to evaluate the appropriateness by comparing with the ergonomic heights theoretically driven from the body heights. The results are as follows: 1) Total number of 179 kitchen heights were measured in the 155 apartments, 20 villa and 4 individual houses. Mean value of the 179 kitchen heights was 851.7mm(？23.3mm). Thus, mean value was very closed to the median value of the Korean Standards(KS) for the kitchen table. The KS has been set for the kitchen table for 3 classes; 800, 850 and 900mm. Around half of the measurements(95 measurements, 53.1%) ranged from 840mm to 860mm which was well match to the center of the KS. 2. Theoretically ergonomic height of the kitchen table was driven by adding 3cm to the half of the body height although the background of this method was vague. However, this method has been referenced in a couple of preceeding researches. Therefore, ergonomically suitable height was calculated with use of this method in this study. Based on the body heights of the women surveyed in 1997, ergonomically suitable height was calculated. It was found that ergonomically suitable height of the kitchen table ranged from 81-83cm. Considering recent trend of increase in body height, these suitable kitchen height would be 85cm or near around. Therefore, the KS of 800, 850 and 900mm for the height of the kitchen table has been appropriately set. 3. If everyone chooses the kitchen table considering one's body height among the KS specification, 95% of the women population will be covered in term of ergonomically suitable kitchen table height. 4. Eight cases were found that the height of the kitchen table was higher than 950mm which is in the beyond of the upper limit of the KS. Four cases were found their kitchen tables have 1000mm or higher than 1000mm. These kitchen tables were evaluated as non-ergonomic design for most generic women populations.
