The pattern of a dance had changed and made a progress delicately according to the change of the myth, religion, and civilization. One genre which had experienced the change for the dance is a mask dance. This dance started from wishes to adore spirit or god with imitated masks of native animals and desire to identify with nature. After the middle ages, it finally became to approach to the artistic state. In that dance, there was used a role of the head of the family which was strongly adapted to the shape of the mask as performing casts After studying symbolic characteristics of the mask dancing, we could conclude these as fol1ows.: First, Masks symbolized the totemism that adores spirit or god. This kind of whole masks were consistently used. Second, Mask was worn for expressing a dancer's cast well. This function of performing cast was in the primitive ages. However at the age which was characterized as the age of the art, the expression of using a mask became various. Third, Mask was mostly related to the head of the family and appeared with the desire to be others not themselves. Since the middle ages, this tendency continued to the modern dance. Now we can see this type at the carnival. The mask was not only an effective means of dance but also an expression of totemism, performing cast, and the head of the family. Therefore it contributed to the growth of the dance a lot.

What is the fundamental cause of the broader gap between East and West medicine? This is a very long story that began in the late Renaissance and still continues today. Why it took so long time from the end of the XIIth century when acupuncture was firt imported to Europe to XX century when it was finally settled in France? We present three cases which caused the delayed establishment : A "blisters" article from Diderot and D'Alembert in the eighteenth century, the practice of acupuncture by Dr. Berlioz in Paris in early 19th century, and the reception of the works of Georges Soulie de Morant in France in the 1930's. We attempt to show the misunderstanding that has always prevailed between the East and West medicines because of different viewpoint : the West has not understood the richness and subtlety of the approach of East asian thought and wanted to "align" the Asian medical modality to west medicine with inappropriate and insufficient "experiments" without enough explanation of the principles and philosophical backgrounds. It was not the matter of technology but the mutual incomprehension of history and culture.

The objective of this study was to investigate the physicochemical characteristics of gelatin extracted from pork skin under soaking in various acid solutions (lactic acid, acetic acid, and citric acid). Gelatin sol was extracted at 8$0^{\circ}C$, frozen at -2$0^{\circ}C$ and lyophilized it for 3 days to be completely dried in freeze drying unit. In the evaluation of gelatin quality, gelatin soaked in citric acid showed higher L- and a-values than those of any other gelatin (p<0.05). Gelatin treated by acetic acid showed the highest gel strength, cohesiveness, and brittleness. The content of hydroxyproline amino acid in gelatin treated by acetic acid was larger than one of gelatin treated in lactic and citric acid in order. From the experimental results, the highest quality of gelatin in all of period, which was soaked in acetic acid and lactic acid, has a more good quality than gelatin soaked in citric acid.

The rate of traffic accidents that occurred in Korea last year is 10 out of every 100,000 people, ranking it 6th among the 35 OECD member countries. The accident rate of children with disabilities and elderly people is also high. The purpose of this study is to introduce traffic safety facilities which have been developed for the reduction of traffic accidents in non-urban areas in Korea through an analysis of the related literature, the accident factors using traffic accident analysis system data and traffic accident characteristics. Traffic safety integrated facilities for ICT-based pedestrian crossings are subject to cross-sectional coverage of child protection zones. The smart safety fence prevents vehicles from parking illegally and informs pedestrians that there is an access vehicle on the pedestrian crossing. The smart bump is designed to warn drivers who are not aware of the pedestrians. In order to standardize the appropriate form and size of the traffic safety facilities for pedestrian crossings, we constructed a standard model for each type, considering the road function, press classification, power, lane number, geometric form, etc. As a result, the rate of traffic accidents involving vulnerable people was reduced. In addition, it is anticipated that the maintenance costs will be reduced by the use of a solar power supply and their compatibility with the existing installed safety fences.
