Treacher Collins syndrome (TCS) is autosomal dominant disorder that occurs approximately 1 in 25,000 to 50,000 live births. The main signs of syndrome are hypoplasia of facial bone and microtia. One in third of them is associated with cleft palate and often shows dental hypoplasia. TCS patients need several number of surgery with general anesthesia throughout their life time for recovery of function and esthetic. Endotracheal intubation of TCS patient is very difficult due to microstomia, retrognathia, choanal stenosis, and decreased oropharyngeal airway. Therefore, general anesthesia of adolescent TCS patient with immature incisor roots has high risk of causing dental trauma. This case is regarding TCS patient who was referred to the Department of Pediatric Dentistry, Yonsei University for avulsed upper left central incisor during endotracheal intubation. The purpose of this report is to emphasize the usefulness of mouth guard to prevent dental trauma when endotracheal intubation is needed for TCS patient.

This study was intended to provide management directions through the provision of tree spatial information as basic data for the preservation of Gyerim(legal historical site), which is located in Gyeongju city, Gyeonsangnam-do, Korea. As a result of the survey of the entire forest, there are a total of 25 species and 510 individuals growing trees. Of these species, 14 species are native and 14 are introduced species. Apart from Sophora japonica, Zelkova serrata, Celtis sinensis, most of the introduced species were adopted without historical basis after designation as a historical site. By a ratio of 36% to introduced species(including 3% of naturalized species; Ailanthus altissima), the historical heritage was significantly damaged. Gyerim, which has over 2,000 years of history, has a total 15 individuals(2.9%) large trees(over 100cm DBH). Ten of these are Salix glandulosa, and in the past, most of this area was considered a Salix glandulosa forest. Currently, however, there are many small trees(under 20cm DBH) for the next generation of growth and the Salix glandulosa forest will continue to decline. Furthermore, most small trees were afforested, so the historicity and place features as a mythological forest will quickly fade.

Sajikdan(a sort of national shrine in Korea) built at the time of foundation of Joseon was entrenched into Sajik Park going through Japanese colonial era and recently the efforts to restore it is in progress. The details of change in Sajikdan in terms of diachronic analysis are as follows: Firstly, the first period refers to one prior to Japanese colonial era from the first king (also named as "Taejo" in Korean) of the Joseon Dynasty, during which it secured and strengthened the presence as a place for performing important national rites in a nation. It was built on the foot of Inwangsan Mt. at the time of the first king in Joseon Dynasty at first, was destroyed fully by fire during a Japanese Invasion period to Korea(1592-98) and afterward its ancestral ritual facilities were completed under the regime of Youngjo. However, as Japanese intervention coming to the fore, its place was destroyed and then ancestral rites were also abolished in 1908. Secondly, next period falls on 1910 to 1944 when it was transformed and entrenched into a park by the Japanese Empire. While facilities related to a park and an heterogeneous building around the part of boundary were set up, the area of altar, a ritual house and d door of Sajikdan were also designated as historical remains and treasures. Thirdly, this period refers to one from Korea's liberation year from Japanese colony(1945) to the year of 1984 when it had a mixed placeness with the statues, monuments and buildings with heterogeneous nature built. Furthermore, a door of Sajikdan was removed and reconstructed over twice due to opening of Sajik Tunnel. Fourthly, a final period falls on 1985 to the present when efforts are in progress to restore the historicity and symbolism of Sajikdan. A plan for restoration is promoted but now is a difficult time suffering from troubles caused by residents' resistance. Scrutinized historical researches through excavation investigation and residents' understanding are required altogether for restoration of Sajikdan.

Treacher Collins syndrome(TCS) is a rare, incurable condition occurring in approximately 1 of 25,000 to 50,000 births. It may occur as a spontaneous mutation out of genetically normal parents or it may be manifested as an autosomal dominant pattern. TCS is characterized by facial deformities such as, underdevelopment of the maxilla, mandible and zygoma, malocclusion, bilateral deformities of auricles, antimongoloid slant of the palpebral fissures. The syndrome is often associated with cleft lip and palate, ear malformations and hearing loss, short stature, and anomalies of the heart and skeleton. Respiratory difficulty associated with air way obstruction may also be observed, and there is considerable difficulty in airway management during general anesthesia. It is necessary that dentists provide safe dental treatments and guidelines to TCS patients by providing adequate understanding about the characteristics of the syndrome and proper ways of managements. The purpose of this study is to report the dental and medical characteristics of the patient who visited the Department of Pediatric Dentistry, Yonsei University for multiple dental caries treatment and to review the literatures of TCS.

In this paper, we investigate the original space, the restoration and the construction methods of royal tombs of the Joseon dynasty Sejong who is one of the most respected kings by our people through old document. Yeongneung(英陵) where King Sejong and Queen Soheon is buried has a unique construction method and history of move which is as equally important as human history. It is estimated that there were documents which contains important materials of construction method in the time when the tomb is moved in 1468. Destroyed during Japanese Invasion of Korea in 1592 most of the records of Yeongneung's construction can be found almost no. Fortunately existing literature "朝鮮王朝實錄", "英陵補土所謄錄" written in 1786, "春官通考" written in 1788 and "英陵寧陵補土所謄錄" written in 1900 are used in this paper. As a result of examining these old documents, 1) Definition of tomb construction, 2) Space and layout of tomb, 3) Characteristics of tomb facilities, 4) Scale and contents of tomb construction, 5) Plants of tombs are included in this paper. World Heritage listed cultural facilities should be well preserved and careful consideration is required to use original construction methods during restoration. Accordingly this study conducted by examining old literature. Through this study including Yeongneung's construction characteristics, understanding of Yeongneung construction and restoration in the future is considered.

Even though the notion exists that wall paper has got a short durability for interior decoration in terms of paper's nature, it can be the most important element among the modern dosing wall papering because of the variation of the walls visual effect. Wall paper hasn't been preserved well according to the paper's character and official records haven't been done well. So, by studying a case in which a room is maintained well, seeing various commercial samples which were used for an advertisement and reading several booklets it is possible to study historical evidence. In regard to wall paper and Papering. data, the commercial historic nature of the traditional wall papering has been recognized again in order to study the root of the technical and commercial background. In theory, the historic background research of traditional wall paper in the past is said to have established its theoretical system and the development of modern wall papering in the middle of Britain in 18th century. Through the theoretical study of wall papering, the following things have been researched: handling don the method of the traditional wall papering and lining paper, stylization of pattern by using the method of continual linking, subdivision of commercial cost and specialization of wallpaper, handing down the past traditional adhesion method, the origin of string wallpaper, utility of traditional wallpaper and its various abilities, the change from the face to face linking to duplicated linking, the development of DIY products by women's wallpaper selections. Put against other materials, wallpaper remains the most popular and preferable product for managing a wall and provides a decorative, wall dosing technique.

The purpose of this study was to seek the spatial organization and prototype landscape through literature reviews, historical evidences, and field surveys for Donggwanwangmyo(東關王廟) shrine in Seoul. The results were as follows : First, the basic layout of the main buildings in Donggwanwangmyo which is the remains influenced by China had bilateral symmetry on the central axis between the north and south. Second, the Chinese forms and features were found at Jeong-jeon and middle gate in Donggwanwangmyo, and the symbolic elements of royal authority was also found in each space of Donggwanwangmyo. Third, spatial organization was classified as the entrance and the ritual area, and the entrance area was maintained by administrators and was used as the place of ritual ceremony preparation. Fourth, the original form of Donggwanwangmyo had been damaged due to the project for making urban park in the 1970s. The most of the existing trees and shrubs which are not suitable to the shrine should be removed to recover the original landscape of Donggwanwangmyo and chui-byoung(翠屛), pond, landscape facilities also needed to be restored. Fifth, Donggwanwangmyo needed to reorganize the pious atmosphere to recover of the shrine environment, and needed to be reclassified as historical site. Finally, some criticizes that Donggwanwangmyo is the result of Toadyism, but Donggwanwangmyo can be used as the valuable tourism resource through the awareness that Donggwanwangmyo was built under the situation of Joseon Dynasty, and organization and understanding that Donggwanwangmyo is a symbolic remains for the exchange between Korea and China.

This study was conducted to calculate the optimum height of trees, estimating a model for the prediction of tree growth for the landscape improvement of the Gyeonghoeru area. For the verification of measures for management, this study conducted a photographic survey of the Gyeonghoeru area and used the Pressler's formula to examine the growth rate of the pine forest of Mansesan. The results of the study are as follows. First, as a result of a field survey and landscape analysis, trees in the Gyeonghoeru area are large ones with more than a diameter at breast height of 30cm, except for weeping cherry trees and persimmon trees, and especially, it is necessary to manage them or replace with small trees through the landscape of Mansesan, which screens the landscape and pruning the trees in the terraced flower garden in the north. Second, as a result of a measurement of the growth rate of trees, for 10 years on average, they grew up by 14% in source diameter and 5% in tree height 5% in south of Mansesan and by 7% in source diameter and 2.4% in tree height in the north of Mansesan. Furthermore, when a simulation was prepared based on the measured growth rate of trees, it was found out that 20 years later, on the landscape on the second floor of Gyeonghoeru, the pine forest of Mansesan would cut off the skyline of Mt. Inwang-san. Third, this study analyzed a landscape improvement simulation and proposed a plan for tree management to take a view of the landscape of the Gyeonghoeru area. This study has a significance that it drew an efficient planting maintenance policy, considering the landscape characteristics of the Gyeonghoeru area.
