There is a general consensus that Baekjeing means Butcher after the Joseon Dynasty. In the Goryeo Dynasty, the title of "Baekjeong" was named as a general farmer's name, "Hwacheok" and "Jaecheok" from the north, but it changed its name to Shin Baekjeong by nationalization policy in the early Joseon Dynasty. They were multicultural Ancestors who worked for jobs which people despised. The purpose of this study is to examine the background and trends of how these were stripped of their identity and to present a direction for deciding on the policy of multiculturalism which is the subject of our society today. Based on the researches of historical researchers, the study examines the multicultural dynamics of old period and observes the present phenomenon by interpreting the statistics of the related institutions of the government. We realized that the reason for the liberation of the Baekjeong has a various causes and its causes are similar to the phenomenon of today 's multicultural society, so that the depth research on each factor will be added to form a desirable policy base for multiculturalism in our country.

One phase liquid crystal formula was developed by using of nonionic surfactants, polyols, water and oils and its physical property was investigated. At the system oft to 1 ratio of POE octyldodecyl ether series, which have Y type (branch type) hydrophobic group, and POE glyceryl monostearate series, Y type hydrophilic group, it was examined that the formula at 7:3, 6:4, and 5:5 ratio of nonionic surfactant : polyols, shows L$\alpha$ , a pattern which is a typical characteristic of liquid crystal structure under the cross microscope polarized film. As results of L$\alpha$ phase diagram study, the formula which had high hydrophilic nonionic surfactant and the 7:3 ratio of nonionic surfactant : polyol appeared to increase the amount of oil containment and to be capable of the lamella formation. Besides it was examined that lamellar liquid crystal formula could contain about 25-40% water between lamella layers and it was transformed into w/o emulsion following as water content increased. When the lamella gel was applied into a human skin, it was investigated that it had effectiveness in increasing transepidermal water content of the skin.
