Buyongjeong, a pavilion in the Rear Garden of Changdeok Palace, was appointed as Treasure No. 1763 on March 2, 2012, by the South Korea government since it shows significant symmetry and proportion on its unique planar shape, spatial configuration, building decoration, and so forth. However, the designation of Treasure selection was mainly evaluated by concrete science, in that the selection has not clearly articulated how and why Buoungjeong was constructed as a present unique form. Therefore, this study aims to clarify the identity of Buyongjeong at the time of construction by considering its historical, ideological, philosophical background and building intention. Summary are as follows: First, Construction backgrounds and characters of Buyongjeong: Right after the enthronement, King Jeongjo had founded Kyujanggak(奎章閣), and sponsored civil ministers who were elected by the national examination, as a part of political reform. In addition, he established his own political system by respecting "Kaksin(閣臣)", Kyujanggak's officials as much as "Kain(家人)", internal family members. King Jeongjo's aggressive political reform finally enabled King's lieges to visit King's Rear Garden. In the reign of King Jeongjo's 16th year(1792), Naekaksangjohoe(內閣賞釣會) based on "Kaksin" was officially launched and the Rear Garden visitation became a regular meeting. The Rear Garden visitation consisted of "Sanghwajoeoyeon(賞花釣魚宴)" - enjoying flowers and fishing, and activities of "Nanjeongsugye". Afterward, it eventually became a huge national event since high rank government officials participated the event. King Jeongjo shared the cultural activities with government officials together to Buyongjeong as a place to fulfill his royal politics. Second, The geographical location and spatial characteristics of Buyongjeong: On the enthronement of King Jeongjo(1776), he renovated Taeksujae. Above all, aligning and linking Gaeyuwa - Taeksujae - a cicular island - Eosumun - Kyujangkak along with the construction axis is an evidence for King Jeongjo to determine how the current Kyujangkak zone was prepared and designed to fulfill King Jeonjo's political ideals. In 17th year(1793) of the reign of King Jeongjo, Taeksujae, originally a square shaped pavilion, was modified and expanded with ranks to provide a place to get along with the King and officials. The northern part of Buyongjeong, placed on pond, was designed for the King's place and constructed one rank higher than others. Discernment on windows and doors were made with "Ajasal" - a special pattern for the King. The western and eastern parts were for government officials. The center part was prepared for a place where government officials were granted an audience with the King, who was located in the nortern part of Buyongjeong. Government officials from the western and eastern parts of Buyongjeong, could enter the central part of the Buyongjeong from the southern part by detouring the corner of Buyongjeong. After all, Buyongjeong is a specially designed garden building, which was constructed to be a royal palace utilizing its minimal space. Third, Cultural Values of Buyongjeong: The Buyongjeong area exhibits a trait that it had been continuously developed and it had reflected complex King's private garden cultures from King Sejo, Injo, Hyunjong, Sukjong, Jeongjo and so forth. In particular, King Jeongjo had succeded physical, social and imaginary environments established by former kings and invited their government officials for his royal politics. As a central place for his royal politics, King Jeongjo completed Buyongjeong. Therefore, the value of Buyongjeong, as a garden building reflecting permanency of the Joseon Dynasty, can be highly evaluated. In addition, as it reflects Confucianism in the pavilion - represented by distinguishing hierarchical ranks, it is a unique example to exhibit its distinctiveness in a royal garden.

This study was conducted to newly examine the original landscape of Buyongjeong(芙蓉亭) and Juhamnu(宙合樓) areas in Changdeokgung Palace(昌德宮), focusing on the modern period including the Korean Empire, and to derive useful research results for restoration and maintenance in the future. The study results can be summarized as follows. First, the artificial island in Buyongji(芙蓉池) was originally made up of a straight layer using well-trimmed processed stone. However, during the maintenance work in the 1960s and 1970s, the artificial island in Buyongji was transformed into a mixture of natural and processed stones. The handrail installed on the upper part of the artificial island in Buyongji is a unique facility that is hard to find similar cases. The handrail existed even during the Korean Empire, but was completely destroyed during the Japanese colonial period. Second, Chwibyeong(翠屛), which is currently located on the left and right of Eosumun(魚水門), is the result of a reproduction based on Northern bamboo in 2008. Although there is a view that sees the plant material of Eosumun Chwibyeong as Rigid-branch yew, the specific species is still vague. Looking at the related data and circumstances from various angles, at least in the modern era, it is highly probable that the Eosumun Chwibyeong was made of Chinese juniper like Donggwanwangmyo Shrine(東關王廟) and Guncheongung(乾淸宮) in Gyeongbokgung Palace(景福宮). Third, the backyard of Juhamnu was a space with no dense trees on top of a stone staircase-shaped structure. The stone stairway in the backyard of Juhamnu was maintained in a relatively open form, and it also functioned as a space to pass through the surrounding buildings. However, as large-scale planting work was carried out in the late 1980s, the backyard of Juhamnu was maintained in the same shape as a Terraced Flower Bed, and it was transformed into a closed space where many flowering plants were planted. Fourth, Yeonghwadang Namhaenggak(暎花堂 南行閣), which had a library function like Gyujanggak(奎章閣) and Gaeyuwa(皆有窩), was destroyed in the late 1900s and was difficult to understand in its original form. Based on modern photographs and sketch materials, this study confirmed the arrangement axis of Yeonghwadang Namhaenggak, and confirmed the shape and design features of the building. In addition, an estimated restoration map referring to 「Donggwoldo(東闕圖)」 and 「Donggwoldohyung(東闕圓形)」 was presented for the construction of basic data.

Taking the boards and couplets of Changdeokgung Palace's Rear Garden as the research object, there were many studies about the humanistic interpretation of landscape elements, but there is no empirical study on Chinese visitors' landscape perception. Therefore, the purpose of this study is to find out how many Chinese visitors pay attention to the boards and couplets; If they are paid attention, how much they are understood and how helpful they are; Whether there is a difference in the perception of the boards and couplets in Buyongji and Ongnyucheon region. First, 97.5% of Chinese visitors read the boards of Changdeokgung Palace's Rear Garden, which proved that most Chinese visitors are highly aware of the boards and couplets because they are familiar with Chinese characters. Second, 'Chinese visitors who understanding of the boards and couplets' was shown to be significant value(0.00 < 0.05) and the average value was 3.39 > 2.97, indicating that the boards had a higher understood than the couplets. And 'Helpful of the boards and couplets in interpreting the entire landscape' was significant value(0.00 < 0.05) and the average was 3.85 > 3.37, indicating that the boards was more helpful than the couplets. Third, the results of the difference in the perception of the boards and couplets in Buyongji and Okryucheon region were that 'the board of Buyongjeong in Buyongji region' and 'the board of Soyojeong in Ongnyucheon region' are related to the surrounding landscape. Additionally, through practical interview, survey respondents(4 person) responded that understanding of the boards and couplets is closely related to their personal interesting orientations, educational background and experience. And the importance of the narrator's role was emphasized in appreciating the landscape by survey respondents.

The object of this study was to analyze the speciality of Korean traditional waterscape and unique landscape formed with reflection of the phases of the time sat the area of Juhabru(宙合樓) in Changdeok Palace as a basic research to find the prototype of Taeaek pond at Changdeok Palace and restoration of the palace. Originally, Taeaek pond at Changdeok Palace was constructed in KingInjo(仁祖) period as a name of Yongji(龍池), later it called Taeaek pond after King Sukjong(肅宗). There is an island as a symbol of the immortal isle, and Chungseojeong(淸署亭), Taiksujae(澤水齋) and Buyongjeong(芙蓉亭) which were built to view the waterscape in Taeaek pond. Buildings were built asymmetrical balance around Taeaek pond because of the morphological character of tetragonal pond. Arrangement of this area has a definite form of axial structure. Yeolgokwan(閱古觀) Gaeyuwa(皆有窩), pavilions, bridges, islands, Osumoon(魚水門) and Juhabru are located on the north and south axis, and island and Osumoon play a role as a intersection and form an east of west axis. In this study, manual of construction for an island and pavilions is provided by analyzing transformational process of island and pavilions at Taeaek pond. Furthermore, kings and officials used to statically enjoy the view around Taeaek pond area, but dynamic fishing and boating activity happened in King Jungjo(正祖) period. These historical backgrounds have an influence on the spatial organization of Taeaek pond. For instance, bridge between Taeaek pond and island was destroyed with the increase of the importance of boating. Symbolic structure around Taeaek pond means 'fish changes to dragon' and 'both of king and officials become one'. Taiksujai, carving fish, Osumoon and Juhabru are provided as a related spatial factors.

This study infers the origin and production period of the , which is in the Onyang folk museum, through analysis and interpretation of the Haeju Palgyeong and exploration of the landscapes and traditions contained in the painting. The first collection of landscapes to Haeju was identified as Haeju Palgyeong by Ku Sa-meng (1531-1604). Yoo Man-ju, writing in 1782, referred to it as Go-palgyeong in 『Heumyeong』 while Haeju Palgyeong was defined as Geum-palgyeong (今八景), which is the Haeju Palgyeong in the earliest period confirmed by literature. is 'Boating on the Nam river (南江泛舟)', 'Lotus viewing at Buyongdang (芙蓉賞蓮)', 'Foot washing at Gwangseokcheon (廣石濯足)', 'Seokbyul at Haeunkyo (泣川送客)', 'Fishing at Haeunjeong (東亭釣魚)' and 'Sea view at Namsan( 南山望海)', and the final two contain a picture that contains 'Viewing the moon at Yeonghaeru (瀛海玩月)' and 'Writing contest and Archery at Baeklimjeong (栢林觀德)' The Suyang Chaemi(首陽採薇), Shingwang-jeoljeol (神光霽雪), and Jiseong falls (池城瀑布) of Gopalgyeong, which were excluded from Haeju Palgyeong, are all landscapes unfolding as a grand site of Suyangsan Mountain. is a result of the reorganization of Seunggyeong centered on Eupchi (邑治), away from the Suyangsan area. It has emerged as a seunggyeong of Haeju. The elaborateness of trying to contain the detailed prizes representing Haeju, such as the specialty sake of Haeju, is revealed. Most of the landscapes depicted in are historic and outstanding spots in Haemok, but the scenes of life related to daily life are properly arranged. In addition, Foot washing (濯足), Fishing(釣魚), Doing laundry (漂母), Lotus viewing (賞蓮), Sending guests (送客), Drinking (飮酒), sea viewing (望海), Moon viewing (玩月), Archery (射藝), Poetry (詩作), Drinking tea (飮茶), and Dancing (歌舞) are of various styles. Compared with the Gopalgyeongs, Haeju Palgyeong did not take into account the distribution of landscapes in the four seasons, and the small-sized view was also broken. When considering the time of the construction of Haeunjeong and the deterioration of Yeonghhoeru, it is believed that was produced in the early- to mid-18th century. is considered to be a painting that contributed to strengthening the sense of intimacy with the local people and promoting the pride of Haeju by showing the representative scenery of Haeju, such as scenic spots and customs, away from the ideal utopia.

Prediction method of permeation flux and sorption characteristics in pervaporation through a polydimethylsiloxane(PDMS) memrane was suggested. The amount of sorption and permeation flux of chloroform, toluene, methanol and n-butanol were calculated with this method and compared with this method and compared with experimetal data. The calculated values of permeation flux and the amount of sorption of good solvents, that is, toluene and chloroform were well agreed with the experimental data. The lower the density of PDMS membrane is, the more permeation flux and sorption quantity were increased. However, the experimental data of poor solvents, that is, methanol and n-butanol were no so well agreed with the calculated values. It is shown that the prediction method suggested in this study may be used without experimetnal for the prediction of permeation flux and sorption quantity of the good solvent on PDMS membrane.

This study develops leggings patterns for pregnant women with increased needs in utilization and necessity. It provides basic data for the development of leggings for pregnant women. The pattern was deformed by analyzing the leggings of U company, and simulated using the DC Suite Program. SPSS 24.0 was used for the analysis. As a result of the appearance evaluation, the primary pattern had many spaces in the thighs, calves, and the upper part; in addition, wrinkles occurred in the upper part and the knee part. The length of the leggings was long and agglomeration in the ankle appeared. Wrinkles were reduced by setting the hip circumference, hip width, and leggings length to reflect the results of the primary in the case of the secondary pattern. A pattern was developed that closely adhered to the body without any wrinkles in the appearance evaluation of the final pattern. Future studies should examine legging patterns of pregnant women according to the material change. Wearing evaluation and appearance evaluation should be done by making actual leggings for pregnant women, not 3D simulation.

This study was performed to offer fundamental data for concentration of persimmon vinegar. The $5.4^{\circ}Bx$ raw persimmon vinegar was concentrated to $20^{\circ}Bx$, $30^{\circ}Bx$, $40^{\circ}Bx$, $50^{\circ}Bx$, $60^{\circ}Bx$ and $70^{\circ}Bx$ concentration by vacuum concentration at $55^{\circ}C$ and diluted to $5.4^{\circ}Bx$ solution with distilled water. The physicochemical properties such as color, viscosity, pH, acidity, organic acid content and free sugar content of various persimmon vinegar concentrates were examined. The recovery yield of water soluble solid to concentrates was 55.5% on $20^{\circ}Bx$ vacuum concentration. Color of $5.4^{\circ}Bx$ persimmon vinegar diluents from concentrates became more dark brown by vacuum concentration. Flow behavior of persimmon vinegar concentrates was pseudoplastic. As the concentration of persimmon vinegar concentrates increased, pH of $5.4^{\circ}Bx$ diluents increased and acidity as acetic acid decreased compared to original raw vinegar. Acetic acid, lactic acid and citric acid were detected, malic acid and oxalic acid were not detected in persimmon vinegar concentrate. Fructose and sucrose only were detected in persimmon vinegar concentrate.
