According to Lee In-ja's research into the cooks of Korea, there are more than 1.2 million culinary professionals in Korea. However, it is hard to find studies on their work environment. From this point, this study aims to examine the shoes worn by culinarians in their workplace and facilitate the improved environment to protect culinary professionals against potential dangers such as slips, occupational and industrial injuries and fatigue, on the basis of the shoes they wear. The research was conducted on a representative cross section of safety shoes currently worn by culinary professionals. The four factors to be tested and measured for the study were weight, slip resistance, internal tearing strength and splitting resistance. Findings on inquiry showed that the shoes tested were quite heavy, slippery and readily liable to splitting under low stress - when compared to standardized base figures. In accordance with the results of this experiment, guidelines for four factors of manufacture were suggested. First, chef's shoes should weigh not more than 1% of a wearers weight. Second, they should exhibit more than 0.50 $\mu$ slip resistance. Third, they should withstand at least 50.0 N/mm tearing strength. And finally, they should have upwards of 3.0 kg/cm splitting resistance.

This study was carried out to investigate improvement of kraft paper sack mixed with recycled paper for sugars and assorted feeds. Four Plies of kraft paper mixed with recycled paper(basis weight : $80g/m^2$) were taken place of two plies of kraft paper made from all pulp(basis weight : $98g/m^2$) and one ply of kraft paper mixed with recycled paper(basis weight : $80g/m^2$) for sugar 30kg. Three Plies of kraft paper mixed with recycled paper(basis weight : $80g/m^2$) were taken place of two plies of kraft paper made from all pulp(basis weight $98g/m^2$) for sugar 15kg and assorted feed 25kg. Physical properties, tensile strength, internal tearing strength and bursting strength, were improved by exchanging kraft paper mixed with recycled paper for kraft paper from all pulp and so kraft paper sacks made from all pulp were no damage in handling. They had so high friction coefficient that there was no danger of collapse on pallet by slipperiness in transportation and handling. And they had high printability so disappearance of printing by the contact with other paper sack in transportation was not found.
