In order to investigate the effect of proteolytic enzymes contained in fruits, ginger, pear, and kiwi were used to measure Warner Bratzler shear force, tensile strength and collagen content of the pork hind legs in a refrigerator at 4 ℃ for 45 hours. Pork had large differences in fat content in each region. Especially, pork hind legs have been classified as non-preferred meat because it is a low fat region and it is hard to make tender texture after cooking. Meat quality depends on texture, especially tenderness, and efforts have been made to soften meat and methods have been used to soften meat using proteolytic enzymes. Warner bratzler shear force values of all treatments were analyzed to be very tender and the shear force value of the control was also very low at 2.33 kg/0.5 inch2. The total collagen content was not significantly different between the control and experimental groups, but insoluble collagen was the lowest at 0.1318g/100g in the kiwi samples. The highest of soluble collagen was also 0.2378g / 100g in the kiwi samples, and there was no significant difference in the treatment group containing the control group. The current study indicated that Kiwi juice had the best tenderization effect on port meat.

Objectives: Dental hygienists are an essential human resource in dental service organizations. However, there are several important persisting problems faced by them, that need to be solved. The purpose of this study was to explore the current situation in dental hygiene education institutions, number of active dental hygienists, and employment distribution across South Korea. Methods: The study gathered statistics of dental hygiene educational institutions, the ratio of active dental hygienists and the number of dental hygienists working across South Korea from officially reviewed websites. Results: Daegu and Gyeongbuk regions house the most number of colleges with dental hygiene programs. The Daejeon and Chungnam regions had the most universities with dental hygiene programs. The activity ratio of dental hygienists decreased every year. Dental hygienists’ employment was highly focused in the Seoul and Gyeonggi provinces. Conclusions: The survey data can be used as basic data for future dental hygienist education to cope with the shortage of active dental hygienists and regional imbalances. This could prove useful to consider the employment of dental hygienists appropriately.
