Ten types of male headgear-Kwonwoonkwan, crown-like headgear, hats with a square flap, hats with feathers, crowns with plumes, Ballip, hats with flat crowns, Somo, turban, and fur hats-were described in Jip-Sah, which was published in the 14th century. Mongolian people used summer headgear, winter hats, and crown ornaments, which had been used until the Ch'ing dynasty of China. From the late 12th century to 1304, the headgear styles remained the same, suggesting that the Mongolian people kept their tradition. Kwonwoonkwan, crown-like headgear, and Somo, presented in Jip-Sah, were also described in U. Yadamsuren's album, a pictorial depiction of the 20th century Mongolian headgear.

This study was investigated to a effect of sociocultural environment on the vicissitudes of headgear in Europe on 19th Century. Form of headgear was increasingly more functional and simple. It was needed various items with various usage. Since Industrial Revolution the french Revolution. A diffusion of sport and increase of leisure time gave rise to entrance of mass headgear with reasonability and simplicity. But female headgear was more decorative than males. Until late 19th century when female has participated in social performance, female headgear was not functional and simple form. More often female took male headgear(fedora, straw boater, cap, tc.) than bonnet when female role-awareness was changed and sport is diffused.

Xinjiang Uygur Autonomous Region is the area with the most Muslim populations in China and the costume of this ethnic minority group was influenced from its surrounding environment and religion. Headgear is one of the important costume elements of Muslim ethnic minority such as Kazakh, Kirghiz, Uzbek, and Tadzhik people, and each group has developed narious forms of it. Especially, we can notice characteristics of headgear in Xinjiang Uygur and four ethnic minority groups through women's headgear pursuant to motive of wear, classification of type, differences and comparability with other areas. Thus, purpose of this study is to investigate women's headgear of Muslim ethnic minority in Xinjiang Uygur Autonomous Region. Based on local data at the Xinjiang Uygur Museum, the study referred to Chinese ethnic minority costume and literature data as well as advanced researches related to Islam, and analyzed characteristics of women's headgear of four ethnic groups in connection with Muslim formation background in Xinjiang Uygur. Women's headgear of Muslim ethnic minority in Xinjiang Uygur can be largely divided into three types; cylindrical, conical and hood type. Headgear was influenced not only by natural environment and weather for protection of body, but also by Islam. Along with strong desire for decoration and expression of racial features, it was used as a means of race discrimination and representation of identity. The religion of Islam within these four ethnic groups grew in accordance with tradition of existing nomadic tribes and regional characteristics, and women's headgear developed in various ways added with religious precepts and nomadic features. Taking everything into consideration, it is found that women's headgear of Kazakh, Kirghiz, Uzbek, and Tadzhik people developed, adopting their own living style and features of minority races instead of remaining identical to the headgear type of Muslim countries in other area.

Phrygia headgear has an important meaning from the perspectives of costume history and cultural exchanges in ancient times. This study is to investigate the prototype of Phrygia headgear through analysis of its manufacturing methods and styles on the basis of prior studies on ancient sculptures and literatures conducted by European researchers and to examine its history and meanings. In these ways, this study will be helpful in understanding the importance of Phrygia headgear in cultural exchanges between the East and the West. Results of this study can be summarized as follows: Phrygia headgear was orn by eastern tribes, so it was a symbol of those from the east in ancient times. Phrygia headgear is frequently found in Greek artistic works of 5th to 4th century BC that depicted eastern tribes. Also, this headgear can be observed in artistic works for Mithras, Attis, or other gods. Since Phrygia headgear's shape is similar to that of Homer's helm, many researchers believe that it might be originated from Homer's helm. This headgear made of oxen scrotum(stierbeutel) or its surrounding skin has a long end at the top. This long end is round and drooping toward the front side. From such unique shape, we top. This long end is round and drooping toward the front side. From such unique shape, we top. This long end is round and drooping toward the front side. From such unique shape, we can draw a conclusion that Phrygia headgear was made of oxen scrotum and its surrounding skin. Dependingy on drooping patterns, there are various shapes, such as the round, tightly swollen one worn by Mithras, the tongue-shaped one found in Basilika S. Apolinare Nuovo's mosaic depicting three wise men, the balloon-shaped one frequently found in Greek vases depicting Scythian, and the one drooping to the side depicted in Alexandersarkophag. Further, some Phrygia headgear has covers for neck and ears. For example, Phrygia headgear worn by Persian Satrap tribe has such covers attached to the head part. Meanwhile, Phrygia headgear worn by Amazone tribe does not show such separate covers, Rather, one piece of oxen skin was tanned and finished to make such covers. Wearing Phrygia headgear can be interpreted in several ways. Use of animal's skin for wearing things is a unique aspect in ancient societies because they believed that wearing animal skin would give them power of the animal. Further, Phrygia headgear made of oxen scrotum was a symbol of reproductive power to women.

This study set out to investigate the identity of everyday headgear, which is often found in many paintings of Tongshinsa, Joseon diplomatic missions to Japan, in the 18th century. That resembles Yu-geon儒巾, but on the top of the headgear are lappets like a roof. The study proceeded as follows: 1) The painting of Tongshjnsa parade in 1711 was used to analyze wearers of everyday headgear because titles of position are shown for each one. 2) Personal records of Tongshinsa in the 18th century were analyzed to examine the cases of everyday headgear. 3) Cases of everyday headgear in literature around the 18th century were examined. Those researches revealed three findings: 1) The names of everyday headgear with a roof shaped top are Gohu-gwan高厚冠 and Yeonyeop-gwan蓮葉冠. 2) Among Tongshinsa, wearers of Gohu-gwan or Yeonyeop-gwan are medical staff, interpreters, painters, and secretaries. However, it doesn't seem to have been distinction between the two types according to social class and position. 3) People wore everyday headgear, that resembled the two types in appearance, such as Mjnja-geon民字巾, Sunyang-geon純陽巾, Hwayang-geon華陽巾, Jeon-geon戰巾, or Jang-geon將巾 in China and Joseon around the 18th century. Among them, Sunyang-geon and Hwayang-geon seem to have had the closest relationship with Gohu-gwan and Yeonyeop-gwan in terms of shape and character of wearers. The analysis of the research findings led to the two following conclusions: 1) Gohu-gwan and Yeonyeop-gwan were worn as one of everyday headgear to represent appearances of a scholar. 2) Gohu-gwan and Yeonyeop-gwan could be changed versions of the similar everyday headgear or different names of them.

This study was designed to investigate the stress intensity and distribution produced by 1mm activation of retraction archwire with $0^{\circ},\;7^{\circ},\;14^{\circ}$ torque and application of high polk J-hook headgear during retraction of four maxillary incisors using the photoelastic stress analysis. The photoelastic model was made with a PL-3 type epoxy resin which was substituted by alveolar bone portion. Each retraction archwire was fabricated from .020' X .025' stainless steel wire which had vertical loops in 7mm height and hooks for high pull J-hook headgear between central and lateral incisors. The high pull J-hook headgear was applied 35 degree backward and upward to occlusal plane with 200gm pet each side The findings of this study were as follows: 1. In case of $0^{\circ}$ torque, the stress was distributed from cervical 1/8 to apex of roots of central and lateral incisors which were the forms of arc mode. When the high pull J-hook headgear was applied, the stress distributed by arc mode was presented from cervical 1/2 to apex of roots of central and lateral incisors. And the stress distributed by following the root surface was presented from alveolar crest to cervical 1/2 of roots of central and lateral incisors. The stress between apecies of central and Lateral incisors was presented also. 2. In case of $7^{\circ}$ torque, the stress distributed by arc mode was presented from cervical 1/2 to apex of roots of central and lateral incisors. And the stress distributed by following the root surface was presented from alveolar crest to cervical 1/2 of roots of central and lateral incisors. When the high pull J-hook headgear was applied, the stress distributed by following the root surface was presented mote apically than without headgear. The stress between apecies of central and lateral incisors was presented also. 3. In case of $14^{\circ}$ torque, the stress distributed by following the root surface was Presented from alveolar crest to apex of roots of central and lateral incisors. When the high pull J-hook headgear was applied, the stress distributed by following the root surface was presented stronger than without headgear The stress between apecies of central and lateral incisors was presented also.

Many types of orthopedic appliances have been developed and used for the treatment of class II malocclusion in pediatric dentistry. Headgear is one of the extraoral appliances, which is used for the purpose of preventing the overgrowth of maxilla. Hotz appliance is used in couple with a cervical headgear for the expansion of maxilla and retraction of maxillary incisors. This case report is about the orthodontic treatment of three patients with class II division I malocclusion. These young patients were given orthopedic treatment in combination with a cervical headgear and Hotz appliance. After the treatment using these extraoral and intraoral appliances, succeeding treatments were practiced considering individual needs as follows: fixed orthodontic appliance for mandibular anterior crowding, Class II activator for retention and additory orthopedic treatment and the retention with Hotz appliance. Young patients with Class II division I malocclusion reported in this study received the orthodontic treatment using a cervical headgear and Hotz appliance as well as appropriate succeeding treatment afterward. All patients received improved convex profiles and lip protrusions by retracting maxilla and maxillary incisors.

The purpose of this study is to observe the effect of high pull headgear on the craniofacial structures of mixed dentition with Class II malocclusion. The cephalometric headplates of 16 children treated by high pull headgeaar during 6 months and 18 children during 12 months were traced, digitized and statistically analyzed. The results were as follows. 1. Inhibition of foreward growth of maxilla was observed in both group. 2. Clockwise rotation of maxilla was observed in both group. 3. There were distal movement of maxillary 1st molar and inhibition of alveolar bone growth of maxilla. 4. There was compensatory extrusion on mandibular 1st molar. 5. The ratio of anterior facial height to posterior facial height was almostly not changed. In the treatment plan of C II malocclusion by high pull headgear, ire must prevent the mandibulasr 1st molar from extruding and for orthopedic effect, at least 6 months is needed.
