This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.

Simultaneous determination of chloragenic acid (CA), 3,4-o-dicafeoyl quinic acid(3,4-DCQA), 4,5-o-dicaffeoyl quinic acid (4,5-DCQA) and linarin in Chrysanthemum sibiricum Fisher was newly established by a reversed-phase high performance liquid chromatography (HPLC). Sample was extracted with 20 ml methanol for 4 hrs. The extract was cleaned up by using Sep-Pak $C_18$ cartridge and 4 ml methanol-$H_2$O(1 : 1) as eluent. Their determination was performed by means of RP-HPLC with Bondapak $C_18$ column (30 cm ${\times}$ 3.9 mm i.d., 10 ${\mu}m$ and gradient elution mode as methanol-5 mM $H_3PO_4$ solution (30 : 70). The established method was applied to various samples purchased. As a result, their content ranges showed to be 0.35~0.55% for CA, 0.46~0.76% for 3,5-DCQA, 0.077~0.23% for 4,5-DCQA and 0.16~2.72% for linarin, respectively.

The present study investigates in detail the combined effects of the Coriolis and centrifugal farce on the development of laminar flows in a square-sectioned U-bend rotating about an axis parallel to the center of bend curvature. When a viscous fluid flows through a rotating curved region, two types of secondary flow occur. One is caused by the Coriolis force due to the rotation of U-bend and the other by the centrifugal farce due to the curvature of U-bend. When the values of Rossby number and curvature ratio are large, the flow field in a rotating U-bend can be represented by two dimensionless parameters ; the Dean number K$\_$LC/=Re/√λ and a body ratio F=λ/Po. For positive rotation, where the rotation is in the same direction as that of the main flow, both the Coriolis force and the centrifugal force act radially outwards, the directions of the two secondary flows are the same. Therefore, the flow structure is qualitatively similar to that observed in a stationary curved duct with a larger f7c. On the other hand, in case of negative rotation, where two farces act in opposite direction, more complex flow fields can be observed depending on the relative magnitudes of the forces.

A comb-like copolymer consisting of a poly(vinyl chloride) backbone and poly(hydroxy ethyl acrylate) side chains, i.e. PVC-g-PHEA, was synthesized through atom transfer radical polymerization (ATRP). This comb-like copolymer was crosslinked with 4,5-imidazole dicarboxylic acid (IDA) via the esterification of the -OH groups of PHEA in the graft copolymer and the -COOH groups of IDA. Upon doping with phosphoric acid (PA, $H_3PO_4$) to form imidazole-PA complexes, the proton conductivity of the membranes continuously increased with increasing PA content. A maximum proton conductivity of 0.011 S/cm was achieved at $100^{\circ}C$ under anhydrous conditions. The PVC-g-PHEA/IDA/PA complex membranes exhibited good mechanical properties, i.e. 575 MPa of Young's modulus, as determined by a universal testing machine (UTM). Thermal gravimetric analysis (TGA) shows that the membranes were thermally stable up to $200^{\circ}C$.

The thought of three religious, Confucianism, Buddhism, and Taoism, had been the mainaxis of Korean spirit of the past. This study is centered on Buddhist and Taoist costume. There have been a lot of studies on Korean costume from many viewpoints. However, there have been few approaches to the inner !"ide of it. That is to say, the research on spiritual back-ground or religious correlation has not done yet. And especially, we are wholly lacking the studies on Taoist costume. In this dissertation, I investigate how they had come to wear Buddhist costume and how it trans, on the basis of related documentary records and existing remains. I also inquiry Taoist costume which was worn at Taoist ceremony in our country, with the help of Korean books and documents and of the sources of Packwoonkwan in China. In the case of Topobyunjeung in Korean costume, in particular, we can catch the source of it only after studying the religious side of Taoist costume and Buddhist costume. As revealed in the theory of Topobyunjeung in Ojuyunmoonja-ngsango by Lee, Kyu Kyung, even old masters and great Confucianists could not know whether Topo, the ordinary clothes of the Sadaeboo, originated from Taoist costume or Buddhist costume. There have been many opinions about the origin, but even now it is true that no one has made it clear. Therefore in this dissertatio I demonstrate mainly how Topo and Hakchangeui appeared in Korean costume through Taoist costume. It is said that Taoists, Buddhists, and literary men wore Topo, Chickchul, and Chickshin in Song dynasty of China. Topo was a clerical robe of Taoists and was also an ordinary clothes. Chick-chul was a clerical robe of Buddhists, and Chick-shin was worn by Zen priests in Won dynaty. Over the Po, Buddhist wore a large robe, namely Kasa, and Taoist wore Packhakchang like Wooeui, when they attended at the religious ceremony. And they regarded such manner of dressing as ceremonial full-dress attire. The style of Topo in China was Saryunggyogeo. The is th say that they put the black Yeon along Sajoo, which are Young, Soogoo, Keum, and Keo, and that they wore Sajodae around their waists so as to let the band down in front of them. Our existing type of Topo is that of Chickryung-gyoin. The characteristics of the type are its Koreum hung on the dress, no Yeon along Sajoo, and Soopok at the back of the dress. And when they put on the dress, they wear Saejodae around their waists. These characteristics considered, we can find the source of Topo from the Po of Chickshin among Buddhist costume. Other types of Topo are those that were transformed elegantly according to our national manners and customs in our country. So-called Wooeui in Chiness Taoism is Hakchang. Originally it was made by weaving for of cranes or other feathered birds. Its remarkable feature is the wide sleeves. Later they called such a robe with wide sleeves Hakchang. Our hakchangeui has Yeon along Sajoo and a belt around waist. We can guess that the features of Topo and wide-sleeved Hakchang mingled and turned into Hakchangeui. Or it might also be that Topa worn by Taoist was regarded as Hakchang and Topa which has Yeon along Sajoo was regarded as Hakchangeui in our country. Such type of Hakchang worn by Taoists was well shown in the Buddhist and Taoist paintings among "The Pictures of Hills, Waters, and Folks" in the latter half of the 16th century. In China Hakchang with a belt around waist could not be seen. Comparing our style of Hakchangeui with the Chinese style, we can recognize the former was similar to that of Chinese Topa. From this, we gather that Topa was regarded as Hakchang, Wooeui worn by Taoists, Ascetics and True Men in Korea. Furthermore I also gather that our Hakchangeui, which has Tongjeong, Koreurn and a belt around waist, was a transformed style in our own country. From the above, we can realize that in costume the three religions, Confucianism, Buddhism, and Taoism, cannot be treated separately although they are different each other in the essential thought. We have to recognize that Korean Costume was established under the closely connected correlation among the religions and that it was transfigured and accepted according to the cultural characteristics. This study is significant in that it is the first attempt to understand Korean costume through the religous approach, which has never been made in our Korean costume studies. We are demanded even more wide and profound investigation on the religious side of costume throughout the general field of costume studies.

Recently, many people have demanded reliable nutritional data even for minor-components. On the other hand, an analytical method for the analyses of vitamin $B_5$ and $B_6$ is lacking. Therefore, this study attempted to validate with accuracy and precision the analysis of vitamin $B_5$ and $B_6$ using a high-performance liquid chromatography (HPLC) method. The vitamin $B_5$ and $B_6$ contents were analyzed using an Agilent 1260 series HPLC system. YMC-Pack ODS-AM ($250{\times}4.6mm$ I.D.) and YMC-Pack Pro RS $C_{18}$ ($250{\times}4.6mm$ I.D.) columns were used for the analyses of vitamin $B_5$ and $B_6$, respectively. In the case of vitamin $B_5$, the flow rate was set to 1.0 mL/min by isocratic elution using the 50 mM $KH_2PO_4$ solution (pH 3.5)/acetonitrile (ACN) (95:5, v/v) with monitoring at 200 nm using HPLC/DAD, whereas the flow rate for vitamin $B_6$ was set to 1.0 mL/min of flow rate by isocratic elution using a 20 mM $CH_3CO_2Na$ solution (pH 3.6)/ACN (97:3, v/v) with monitoring by excitation at 290 nm and emission at 396 nm using HPLC/FLD. The column temperature was set to $30^{\circ}C$. The injection volume was $20{\mu}L$ for each experiment. The specificity of the accuracy and precision for vitamin $B_5$ and $B_6$ were also validated by HPLC. The results showed high linearity in the calibration curve for vitamin $B_5$ ($R^2=0.9998^{{\ast}{\ast}}$), the limit of detection (LOD) and limit of quantitation (LOQ) were 0.4 mg/L and 1.3 mg/L, respectively, In contrast, for the calibration curve of vitamin $B_6$, which showed high linearity ($R^2=0.9999^{{\ast}{\ast}}$), the LOD and LOQ were 0.006 mg/L and 0.02 mg/L, respectively.

The 13 genre paintings by Junkeun Kim in the book "Korean Games(by Stewart Culin 1858~1929)" were used to study the late $19^{th}$ century's basic costumes and Games style in Korea. The people who appear in the paintings are 26 adult males, 2 minor males, 2 adult females and 3 kisaengs. Typical men wore 'Jeogori' which had various colors and white linings with a reached hip line, and knotted with a 'go-rum' on the right side. They also wore, white colored 'Baji' with colorful sash that were knot below knee or ankle together with 'Hang-jun' or 'Daenim'. They wore 'Beoseon'. Some men wore 'Po' whose colors were blue, green, indigo, white. The general women wore 'Jeogori' in deep green and light pink, indigo, green, red, and they matched with colors for 'Kit' and, 'Go-rum', 'Kut-dong' and its 'Go-rum' was short and narrow. It was so fit and short with narrow sleeve. It had 'Dunggun-kit'(round head collar) with white 'Dong-jung' and so it fit at neck. They wore 'Chi-ma' whose color was red, light green, or light indigo. It contrasted with 'Jeogori'. The width of 'Chi-ma' was big enough. Then white inner slacks came out under the skirt. Traditional Korean games can be classified according to age and gender. Then the games can be further classified into three categories : men's games, women's games, and games for all. The games for adult are an archery practice, hunting, shovel work with a karae, making a bow, drawing Jongkung-chart, Korean chess, playing paduk, and the Korean card game. A swing is a game for women. Games for both men and women are dice play, and domino game. Games for both adult and minor males are sledge, and tightrope walking. Through genre paintings in the $19^{th}$ century, I reached a conclusion that basic costumes are similar to 'Hanbok' at the present time and the method of wearing them has not changed much. It appears that the originality of traditional costumes has been maintained.
