The Bunhuangsa stone pagoda, constructed in AD. 634, National Treasure no. 30, has been named as 'brick-copied pagoda' since the Japanese-ruling period by scholars. It is said that the Chinese brick pagoda was its precedent model, however the Bunhuangsa Pagoda is the oldest of all the Chinese-style brick pagodas except one, the Sungaksa Pagoda. The Chinese pagoda cannot have been a precedent model to copy due to its complex detail of wood vestige, as the Bunhuangsa pagoda is simple form without ornament. Domestic brick pagodas cannot have been a precedent model to copy as well, because all the domestic brick pagodas are younger than the Bunhuangsa Pagoda. Therefore, the terminology 'brick-copied pagoda' is a fallacy; it is rather that later brick pagoda copied the precedent the Bunhuangsa stone pagoda. The Bunhuangsa Pagoda is simply a piled-up pagoda of thick or thin, big or small slates of stone, facing only one smooth side and therefore needing nothing to relate to brick. The originality of the pagoda is more related to simple piled-up Indian stone stupa rather than Chinese brick pagoda. The roof form of its gradually stepped projection comes from the harmika of the summit of Indian stupa. Contrary to general history, old Silla Dynasty imported Buddhism directly from India by sea. From written national history and by temple foundation history, the Indian Buddhism evangelist possibly made influence to the erecting of temple and pagoda. The original wrong terminology has made a harmful effect gradually to the naming of mass-styled stone pagoda of only carved stepped-roof form after brick-copied pagoda. The false term 'brick-copied pagoda' should be discarded, which comes with superficial observation based on toadyism to China and colonialism to Japan. Instead of the fallacious term, this paper suggests multi-storied 'piled-up pagoda with slate stone.'

Area exclosure is a widely practiced intervention of restoring degraded lands though its impact in sequestering terrestrial and soil carbon is scanty. The study was initiated to investigate the effect of exclosure of different ages on carbon sequestration potential of restoring degraded dryland ecosystems in eastern Tigray, northern Ethiopia. Twelve plots each divided into three layers were randomly selected from 5, 10 and 15 years old exclosures and paired adjacent open grazing land. Tree and shrub biomasses were determined using destructive sampling while herb layer biomass was determined using total harvest. The average total biomass obtained were 13.6, 24.8, 27.1, and 55.5 Mg ha^-1 for open grazing, 5 years, 10 years, and 15 years exclosures respectively. The carbon content of plant species ranged between 48 to 53 percent of a dry biomass. The total carbon stored in the 5 years, 10 years and 15 years age exclosures were 39 Mg C ha^-1, 46.3 Mg C ha^-1, and 64.6 Mg C ha^-1 respectively while in the open grazing land the value was 24.7 Mg C ha^-1. Carbon stock is age dependent and increases with age. The difference in total carbon content between exclosures and open grazing land varied between 14.3-40 Mg C ha^-1. Although it is difficult to extrapolate this result for a longer future, the average annual carbon being sequestered in the oldest exclosure was about 2.7 Mg C ha^-1 yr^-1. In view of improving degraded area and sequestering carbon, area exclosures are promising options.

The Korean have admired and lived with decorums through Jeol, a representative practical formality which expresses the decorums intensively. Jeol is the way of greeting native to Korea and an intangible culture close to Korean life style. To be remained as a culture, the traditional propriety Jeol should reconcile to the present life feflecting our history. On this viewpoint, the purpose of this research is to furnish the authority of the creative inheritance on the settlement of Jeol and other decorums suitable to the present. This research is consisted of 1) the study of the meaning of Jeol and 2) the hidtorical research through records. 'Jurye' is regarded as the oldest literature on the systematic explanation about Jeol and has been very often used down the ages. Jindong in 'Jurye' and Kodu in 'Karyejipram' are the same Jeol which expresses the grief in funeral rites. In 'Seonghosaseol', Abae which stands one knee is explained and investigated as the case of offense by the literature. And it is also interpreated as a Jeol with respect, while many other Jeol is to fall an both of kness, Abae is not performed generally. 'Yeki' has brief explanation about Kongsu Manner (to hold hands), Jeol between the king and minister, host and guest, Buinbae, Jeol in custom, wedding ceremony and funeral ceremony and Jeol in drinking manner. In 'Chunchukongyangjeon'. there is the explanation about Jeol of the minister who comes back after his duty to the king. 'Sunjajiphae' interprets Bae and Kyesang and informs that Kuesu is the most respectful Jeol only to the king, 'Seojeon' proves the Jeol habitually used in all kinds of ceremonies and etiquettes. 'Jeongbomunheonbigo' introduces the custom of Jeol in Shilla, Koguryo, Buyeo, Koryo eras by using literature and shows the commoness of both kneeling down generally. The result of this research has the meaning for the creation of life culture in the basis of the spirit 'Onkojisin'(reviewing the old and learning the new) by establishing the present Jeol with tradition.

Video poxy server which is located near clients can store the frequently requested video data in storage space in order to minimize initial latency and network traffic significantly. However, due to the limited storage space in video proxy server, an appropriate deletion algorithm is needed to remove the old video data which is not serviced for a long time. Thus, we propose an efficient video data deletion algorithm for video proxy server. The proposed deletion algorithm removes the video which has the lowest request possibility based on the user access patterns. In our algorithm, we arrange the videos which are stored in video proxy server according to the requested time sequence and then, select the video which has the oldest requested time. The selected video is partially removed in order to free up storage space in video poky server. The simulation results show that the proposed algorithm performs better than other algorithms in terms of the block hit rate and the number of block deletion.

This paper is a study of clothing recorded in$\boxDr$Shin Ching$\boxUl$.$\boxDr$Shin Ching$\boxUl$is the oldest poetry, which written in early west-Zhou to mid Spring and Autumn Period. In this book, clothing is classified with men's women's and fabrics. But only the men's costume is included in this paper, and others will be studied later. As a result, men's clothing includes Qui, Mian Fu, Bian Fu, Yi Shang, Po, Ze, the armour, the belt ornaments, the hair ornaments and the hair styles, the shoes. 1. Qui is depicted at 11 poetries. It's materials are sheep, wolf, bear etc. The materials and color are differentiated according to the class. 2. Mian Fu is depicted at 20 poetries. There are depictions about the embroidered black garment and a red skirt, and also about inner blouse, Chong er, Chi xi etc. 3. Bian Fu is depicted at 5 poetries and there are three types. 4. Yi Shang is depicted at 9 poetries and classified with two types. One is twp piece style, and the other is one pieced style. 5. Po and Ze is depicted at 1 poetry. Po is sa long coat with lining and Ze is a under-wear. The armour and the helmet are depicted at 2 poetries. 6. The belt ornaments are classified with two styles. One is decorational and the other is practical. At 7 poetries they are depicted. 7. The hair ornaments includes a hat and a hair style. Also, the shoes are depicted and there are two styles. Such a results can clarify the men's costumes of Zhou and may be a raw datas about the costumes of old China.

The Axes and Adzes are the oldest tools since the beginning of human history which is used to cut the tree and make part of architecture such as boards, square timber etc. Nowadays, these old woodworking tools especially "Jagui(자귀)" (adze) has been almost disappeared at the working site of residential and cultural properties. It is necessary to study Korean traditional woodworking tools to keep Korean traditional skill and technology. It has been reviewed the change of shape of "Jagui(자귀)" (adze) from before Samhan (삼한) period to Joseon Dynasty through excavated relics and paintings and summarize as follows: Based on excavation relics of Dahori, both plate type blade and pocket type blade are used for "Tokki(도끼)" (axe) and "Jagui(자귀)" (adze). The excavated "Jagui(자귀)" (adze) from Jeongbaikri 356 tomb, near Pyongyang is prototype of "Jagui(자귀)" (adze) used nowdays which has almost same shape as well as the insert method of blade and handle. The auxiliary handle is inserted to blade and the main handle is inserted to the auxiliary handle which is different from the method of Chinese and Japanese "Jagui(자귀)" (adze). The length of handle of "Jagui(자귀)" (adze) until late Joseon Dynasty is short by which we assume it is used for a sitting position as hand held Jagui and from that time long handle has been introduced for a standing position which is called "Sunjagui(선자귀)". "Jagui(자귀)" (adze) has been used since the beginning of human history but it is almost disappeared at the most of woodworking site which is the crisis of Korean traditional architecture and we have to do something to keep it.

One of the characteristics features of Chinese Medicine is recognized as the practical use of combinations of crude drugs in the forms of various prescriptions according to the symptoms of illness. Such crude drugs are mostly dried plant roots, rhizomes, leaves, fruits and seeds, sometimes dried animla organ preparations even fossils or minerals. In the oldest book of Chinese Medicine, Sang Han Ron, 113 prescriptions were described in which about 80 crude drugs were included, and in other old literature, Shin Nong Bon Tcho Keun, 363 crude drugs were recorded. Such drugs, in particular, those included in Sang Han Ron are generally low toxic, and the prescriptions are acting mild with less side effects, but obviously not so easy task to determine the effect of the indivisual drug from the total effects of various prescriptions which are generally consisted of many kinds of crude drugs. About 200 years ago, in the middle of Edo era, a Japanese medical doctor, Yoshimasu Todo wrote a series of books named "Yakucho", in which he described the essential various prescriptions in which the certain drugs plays the main role. This book is very suggestive to evaluate the effects of some Chinese drugs. The actual effects of Chinese medicine and drugs have widely been recognized by the East Asian peoples during their long age experiences, but still it has not been studied sufficiently by modern scientific methods to give generally acceptable evidences. During past some years, my collaborators and I have been engaged to study some well-known Chinese drugs chemically to find out the active principles in determining their chemical structures under the collaboration of pharmacologists, Prof. K. Takagi and his coworkers. In the present lecture, I would like to present two topics from our recent investigations: The studies on the principles of Paeony and Ginseng roots.

This study has been made for the enlargement of a previous work of 1964 which was carried out by an author of this work emphasizing the stratigraphy, micropaleontology, depositional environment, and structural tectonics of the studied area. The stratigraphic sequences of the area are groupped into four units: (1) basement of Pre-Cretaceous, (2) lower sediments of Late Cretaceous, (3) upper sediments of Late Cretaceous and (4) igneous rocks of Late Cretaceous and Tertiary (?). The oldest rocks consisting of schists and gneisses of Pre-Cambrian and schistose granite' of Jurassic age are exposed at the base of this area on which the thick Cretaceous sediments were deposited. These old rocks are unconformably overlain by the lower sedimens of Late Cretaceous composed of three members, an alternation of black shale and tuffaceous sediments, fine tuff and rhyollite flow in ascending order. The oily material was found from the black shales of the alternation m"ember as semi-solid greaselike material, oily order and microscopic granular spherical material and oily stain. The lower sediments are also overlain, in low-angleunconfromity, by the 'upper sediments having three members, an alternation of volcanic conglomerate and andesitic tuff, rhyollitic tuff and andesite flow in the same order. The igneous suit of diabase, diorites, biotite granite, porphyritic granite and porphyries of the latest Cretaceous and small exposure of pitchstone of Tertiary (?) intruded into the pre-existed rocks above mentioned. Considerable amount of ostra- coda microfossils have been chemically extracted from the black shales of the lower sediments and the identification of the fossils suggests that the depositional environment of the sediments were under fresh or brackish water condition. The distribution of the geology and its tectonic data also suggest a combination of dome and basin structures in the area of San-i peninsula and Jin-do as shown in fig. 8. Between these two units an anticlinal structure was constructed. As a result of this study, a seismic survey in a district between U-su-yong and north coast of Jin-do is recommended to determine the underground features.

Jikji, Memory of the World of UNESCO, the world's oldest extant movable metal print book, is a cultural heritage to give motivation for IT power of Korea. Although the cultural value of Jikji is understood in Korea, the value of cultural assets is not satisfactory and the commercialization is not sufficient. Furthermore, most Jikji product designs on the market are simple and limited mainly for the old generation. The purpose of this study is to design fashion-cultural products suitable for young people who will be responsible for this cultural inheritance. The methods of this study were to make the design development through literature research and a case study for Jikji products on the market. For developing the products suitable for young people, 308 university students in Chungju were surveyed. To express end products, computer graphic program, Illustrator CS5, was used. The results of this study showed that the products on the market were not targeted for use by young people. The younger generations want modern and interesting design. Among the 8 design motives that are planned for design development, the most preferred motive numbers, 3, 7, and 8, were used. Design items, such as scarf, wallet and t-shirts, were selected by the result of survey and 3 scarves, 4 wallets, 3 t-shirts, a total of 30 items were developed. The designed products in this study can inform the cultural resource of Korea and contribute to raise the cultural value if they are commercialized.

From ancient Antarctic glacier ice, we extracted total genomic DNA that was suitable for prokaryotic 16S rDNA gene cloning and sequencing, and bacterial artificial chromosome (BAC) library and end-sequencing. The ice samples were from the Dry Valley region. Age dating by $^{40}Ar/^{39}Ar$ analysis on the volcanic ashes deposited in situ indicated the ice samples are minimum 100,000-300,000 yr (sample DLE) and 8 million years (sample EME) old. Further assay proved the ice survived freeze-thaw cycles or other re-working processes. EME, which was from a small lobe of the basal Taylor glacier, is the oldest known ice on Earth. Microorganisms, preserved frozen in glacier ice and isolated from the rest of the world over a geological time scale, can provide valuable data or insight for the diversity, distribution, survival strategy, and evolutionary relationships to the extant relatives. From the 16S gene cloning study, we detected no PCR amplicons with Archaea-specific primers, however we found many phylotypes belonging to Bacteria divisions, such as Actinobacteria, Acidobacteria, Proteobacteria $({\alpha},\;{\beta},\;and\;{\gamma})$, Firmicutes, and Cytophaga-Flavobacterium-Bacteroid$. BAC cloning and sequencing revealed protein codings highly identical to phenylacetic acid degradation protein paaA, chromosome segregation ATPases, or cold shock protein B of present day bacteria. Throughput sequencing of the BAC clones is underway. Viable and culturable cells were recovered from the DLE sample, and characterized by their 16S rDNA sequences. Further investigation on the survivorship and functional genes from the past should help unveil the evolution of life on Earth, or elsewhere, if any.
