  • The Avatamsaka Sutra copied in ink on the white paper of Shilla Period is the oldest manuscript in korea. This Avatamsaka Sutra is volume 1-10 and 44-50 of the 80 volume's transcription. According to the postscript, written with 528 letters at the end of the volume 10 and 50, this sutra is made during A.D. 754-755, for six months by the order Master Yon-gi(綠起 法師) who founded Hwaumsa Temple(華嚴寺.) It explains the procedure of the ritual and production method of the sutra-copying, and also shows the 19 participants with their name, address, official title, and etc. When the sutra was founded, volume 1-10 were so congealed that we could not open the volumes. And volume 44-50 was prohibited to take photograph for preservation. According to the recent examination, it proved that this sutra is the treasure for the study of the characters made by Empress Wu Zetian(則天武后.) The characters made by Empress Wu Zetian(A.D. 625-705) are new shape of chinese characters which is different from the traditional characters. After the demise of the Queen, the characters were not used any more officially, but privately some people used the characters for personal tastes and interest. The characters in the sutra includes 512 characters of 13 kinds of Empress We Zetians'. Compared to the Tun-huang version of the sutra, this is far better treasure for the study of Empress We Zetians' characters in terms of the number of the character and the their use of frequency. The Avatamsaka Sutra of Shoso-in(正倉院) in japan copied in A.D. 768 does not use the Empress We Zetians' characters. In this respect, this Shilla Avatamsaka-Sutra is a unique one preserves the original forms of Chinese translation at that time.

  • Since the outbreak of the brown planthopper (Nilaparvata lugens) in 1915 caused tremendous losses in rice production, one of the more effective method of prevention of such a disaster could be the establishment of longterm forecasting system, In 1916 the author indicated there was a correlation between sunspot activities and brown planthopper and the white back planthopper outbreaks. However, the examples seem to be too small size to state a definite correlation. The purpose of the present study IS to revi~w the history of the brown planthopper outbreaks, and to establish a more effective forcasting system. The present forcasting methods are based on light trap catches of adults which already migrate into this country from mainland China. The regular cycle of 11.2 years of sunspot activity began in 1710, and was continued to present. To gather more records of brown planthopper, the author checked 'Joseon Wangjo Silrok' and analized the so-called 'Hwang' 'Hwang-chung' and 'Chung' which have multiple meanings, together with 'Samguk Sagi' 'Goryo Sa' and 'Munheon Bigo.' The results obtained by the about from review of these old literature citations revealed that ten species of insect and unknown species were involved: i. e., pine moth (Dendrolimus spectabilis), army worm (Mythimna separata), brown planthopper (Nilarvata lugens), white-back planthopper (Sogatella furcifera), migratory locust (Locutsa migratoria), rice stem borer (Chilo suppressalis,), mole cricket (Gryllotalpa africana), rice-plant weevil (Echinocnemus squameus), cut worm (Euxoa segetum), and mulberry pyralid Margaronia pyloalis) The suspected incidence of planthopper in old records expressed by 'Hwang' or 'Chung' revealed a total or 25 out of 37 in 'Samguk sagi,' 21 out of 49 in 'Goryo sa,' 9 of 73 in 'Wanjo-silrog,' and none of 8 in 'Munheon bigo' were planthoppers. Therefore, a total of 36 out of 167 records of insect incidence in the old literature can be possibly attributed to planthoppers. The brown planthopper and white-back planthopper migrate together to Korea every year from mainland China, However, the number of each species are differ by year. In 1975 outbreak the brown planthopper was dominant; and the white-back planthopper prevailed in 1946 and 1977 outbreaks, During the course of this study, the author was able to add a new record of outbreak of planthop per. In 1916 the white-back planthopper outbreak caused serious losses in Chungcheong-namdo and Jeonla-namdo, with losses estimated as high as 160 and 190 thousand seok (23.2 and 27.5 thousand M/T), in Naju and Secheon county, respectively. Since 1912, major outbreaks of brown planthopper or white-back planthopper have been recored 5 times. These occurrences coincide and well matched the period of minimum number of sunspots, With these authenticated records of planthoppers, the author believes there is a close correlation between brown planthopper and white-back planthopper outbreaks in Korea and sunspot activities. Therefore, in years of low number of sunspots, we should watch for and expect outbreaks of these. insects. At this time, it will be necessary to provide all possible prevention measures.

  • This study intends to examine the background and the procedure of the carving of the tablets of the second edition of Dae-Jang-Mock­Lock(재조대장목록). the time and the route of the moving of the tablets. into Haein-sa, and the contents and the system of it. This study is mainly based on the second edition of Dae-Jang-Mock-Lock. But the other closely related materials such as restored first. edition of the Dae- Jang-Mock-Lock, Koryo Sin-Jo-Dae-Jang-Byeol-Lock (고려신조대장교정별록). Kae-Won-Seok-Kyo-Lock (개원석교록). Sok-Kae­Won-Seok-Kyo-Lock (속개원석교록). Jeong-Won-Sin-Jeong-Seok-Kyo­Lock(정원신정석교록), Sok-Jeong-Won-Seok-Kyo-Lock(속정원석교록), Dea-Jung-Sang-Bu-Beob-Bo-Lock(대중상부법보록), and Kyeong-Woo-Sin-Su-Beob-Bo-Lock(경우신수법보록), are also analysed and closely examined. The results of this study can be summarized as follows: 1. The second edition of Tripitaka Koreana(고려대장경) was carved for the purpose of defending the country from Mongolia with the power of Buddhism, after the tablets of the first edition in Buin-sa(부이사) was destroyed by fire. 2. In 1236. Dae-Jang-Do-Gam(대장도감) was established, and the preparation for the recarving of the tablets such as comparison between the content, of the first edition of Tripitalk Koreana, Gal-Bo-Chik-Pan-Dae­Jang-Kyeong and Kitan Dae- Jang-Kyeong, transcription of the original copy and the preparation of the wood, etc. was started. 3. In 1237 after the announcement of Dae-Jang-Gyeong-Gak-Pan-Gun­Sin-Gi-Go-Mun(대장경핵판군신석고문), the carving was started on a full scale. And seven years later (1243), Bun-Sa-Dae-Jang-Do-Gam(분사대장도감) was established in the area of the South to expand and hasten the work. And a large number of the tablets were carved in there. 4. It took 16 years to carve the main text and the supplements of the second edition of Tripitaka Koreana, the main text being carved from 1237 to 1248 and the supplement from 1244 to 1251. 5. It can be supposed that the tablets of the second edition of Tripitaka Koreana, stored in Seon-Won-Sa(선원사), Kang-Wha(강화), for about 140 years, was moved to Ji-Cheon-Sa(지천사), Yong-San(용산), and to Hae-In-Sa(해인사) again, through the west and the south sea and Jang-Gyeong-Po(장경포), Go-Ryeong(고령), in the autumn of the same year. 6. The second edition of Tripitaka Koreana was carved mainly based on the first edition, comparing with Gae-Bo-Chik-Pan-Dae-Jang-Kyeong(개보판대장경) and Kitan Dae-Jang-Kyeong(계단대장경). And the second edition of Dae-Jang-Mock-Lock also compiled mainly based on the first edition with the reference to Kae-Won-Seok-Kyo-Lock and Sok-Jeong-Won-Seok-Kyo-Lock. 7. Comparing with the first edition of Dae-Jang-Mock-Lock, in the second edition 7 items of 9 volumes of Kitan text such as Weol-Deung­Sam-Mae-Gyeong-Ron(월증삼매경론) are added and 3 items of 60 volumes such as Dae-Jong-Ji-Hyeon-Mun-Ron(대종지현문논) are substituted into others from Cheon chest(천함) to Kaeng chest(경함), and 92 items of 601 volumes such as Beob-Won-Ju-Rim-Jeon(법원주임전) are added after Kaeng chest. And 4 items of 50 volumes such as Yuk-Ja-Sin-Ju-Wang-Kyeong(육자신주왕경) are ommitted in the second edition. 8. Comparing with Kae-Won-Seok-Kyo-Lock, Cheon chest to Young chest (영함) of the second edition is compiled according to Ib-Jang-Lock(입장록) of Kae-Won-Seok-Kyo-Lock. But 15 items of 43 vol­umes such as Bul-Seol-Ban-Ju-Sam-Mae-Kyeong(불설반주삼매경) are ;added and 7 items of 35 volumes such as Dae-Bang-Deung-Dae-Jib-Il­Jang-Kyeong(대방등대집일장경) are ommitted. 9. Comparing with Sok-Jeong-Won-Seok-Kyo-Lock, 3 items of the 47 volumes (or 49 volumes) are ommitted and 4 items of 96 volumes are ;added in Caek chest(책함) to Mil chest(밀함) of the second edition. But the items are arranged in the same order. 10. Comparing with Dae- Jung-Sang-Bo-Beob-Bo-Lock, the arrangement of the second edition is entirely different from it. But 170 items of 329 volumes are also included in Doo chest(두함) to Kyeong chest(경함) of the second edition, and 53 items of 125 volumes in Jun chest(존함) to Jeong chest(정함). And 10 items of 108 volumes in the last part of Dae-Jung-Sang-Bo-Beob-Bo-Lock are ommitted and 3 items of 131 volumes such as Beob-Won-Ju-Rim-Jeon(법원주임전) are added in the second edition. 11. Comparing with Kyeong-Woo-Sin-Su-Beob-Bo-Lock, all of the items (21 items of 161 volumes) are included in the second edition without ;any classificatory system. And 22 items of 172 volumes in the Seong­Hyeon-Jib-Jeon(성현집전) part such as Myo-Gak-Bi-Cheon(묘각비전) are ommitted. 12. The last part of the second edition, Joo chest(주함) to Dong chest (동함), includes 14 items of 237 volumes. But these items cannot be found in any other former Buddhist catalog. So it might be supposed as the Kitan texts. 13. Besides including almost all items in Kae-Won-Seok-Kyo-Lock and all items in Sok-Jeong-Won-Seok-Kyo-Lock, Dae-Jung-Sang-Bo­Beob-Bo-Lock, and Kyeong-Woo-Sin-Su-Beob-Bo-Lock, the second edition of Dae-Jang-Mock-Lock includes more items, at least 20 items of about 300 volumes of Kitan Tripitaka and 15 items of 43 volumes of traditional Korean Tripitake that cannot be found any others. Therefore, Tripitaka Koreana can be said as a comprehensive Tripitaka covering all items of Tripitakas translated in Chinese character.

  • This study examined and analyzed ancient writing and poetry regarding cases of appreciating plants by using pots in a garden of a palace or private houses by ancestors, and examined shape and planting method of plant species and potted plants, arrangement and preference of potted plants. As for the method of the study, description research method which examines and interprets poem and painting based on potted plants. The results of this study is summarized like the following. First, the plants which were favorably used for potted plants include 19 kinds such as Prunus mume, Pinus densiflora, Pinus pumila, Phyllostachys spp., Camellia japonica, Punica granatum, and Gardenia jasminoidesa, and as for herbs, 12 kinds such as Chrysanthemum monifolium and Nelumbo nusifera . Second, the species which were specially arranged into artificial shapes include Prunus mume and Pinus densiflora. The two plants made the shape of severe curves of stems such as Wangpi. Gyuban, and Bangan, and there are Pinus densiflora dwarfed potted plant whose roots are stretched on Prunus mume grafted into a strange stump and an oddly shaped stone. For the beauty of the dwarfed tree shape, pine cones are added to an old Pinus densiflora or Parthenocissus tricuspidata is planted to stems, and additional method of making moss on the soil, which is called 'Jongbunchuigyeong'. As for planting method, water culture, planting on a stone, planting on a charcoal, and assembled planting are expressed in poetry. Third, as for external space for potted plants, a place where a king stays, a bed room for a king, surrounding areas and gardens of private houses, and step stones were used as a space which adds artistic effects. Potted plants are placed on a table in a library, on a desk, on a drawer, and near a pillow as a small items in a room, and scholars enjoyed original characteristics and symbolism of the potted plants. Fourth, at the time of flowering of Prunus mume, poetry event was held to enjoy the tree and writing poetry begun. And at the time of flowering of Chrysanthemum monifolium, the flowers were floated in a liquor glass or shadow play was enjoyed. Fifth, potted plants played the role of garden ornaments in elegant events of a palace, the gentry, wedding ceremony, and sacrificial rites. Sixth, potted plants were used as tributes between countries, donation to a king, or a gift of a king. In addition, there were many cases where scholars exchanged potted plants and there is the first record of giving a potted plant in 'Mokeunsigo' by Mokeun Isaek, scholar in the late era of Goryeo. Seventh, at the time of flowering Prunus mume, Chrysanthemum monifolium, Gardenia jasminoides, Nelumbo nusifera, and Narcissustazetta var. chinensis, they enjoyed the particular fragrance and express it into poetry. Eighth, plant species from southern parts such as Camellia japonica, Daphne odora, Gardenia jasminoides, Citrus unshiu, Phyllostachys spp., Punica granatum, Rosa rugosa, and Musa basjoo, or foreign plant species, and species weak against the cold were utilized as pot plants for enjoying green trees indoors in northern central province in harshly cold winter.

  • The purpose of this research is to investigate the reality behind Jeongjo's enjoyment of the palace garden. If I were to summarize the results of this research, they are as follows: First, The 'Sanghwajoeoyeon(賞花釣魚宴)' has the differentiation which decided and regularized the rules and the regulations with the annual meetings for the Kyujanggak(奎章閣). Jeongjo had held the events five times. Second, The 'Seshimdae(洗心臺) Excursion' is based on the tragic personal history of Jeongjo. There were four events. Third, Jeongjo had enjoyed the 'viewing of the waterfall(觀瀑)' of the Okryucheon(玉流川) where a lot of the water overflows right after it rains. This is worth the special mention with regard to the point that it is a temporary landscape and not an usual landscape. Fourth, As an event for the military officers, the 'Seoljungryonghohwe(雪中龍虎會)' was held seven times. This event had been held in the middle of the winter. And each of the attendees skewered a pheasant and roasted and ate it. Also, it emphasized the sovereign and the subjects being the partners of the joys and the sorrows by giving the alcoholic drinks and the music. Fifth, Jeongjo had consoled the hard work by the civilian subjects either by holding the brazier feast(煖爐會) in the winter or by granting the alcoholic drinks and the foods according to the historical facts of the brazier feasts. Sixth, Jeongjo was good at archery and enjoyed it. During the period of his reign, Jeongjo held twice Yeonsarye(燕射禮). Seventh, Jeongjo soothed his desire to get out of the busy everyday life at the royal palace garden. While appreciating the natural landscape of the backyard, he was awakened of the meaning of the Book of Changes(周易) in which all the things had been created and changed. Eighth, At the royal palace garden, Jeongjo actively prepared the place for enjoyment by the sovereign and the subjects together. It is judged that this is because, in order to materialize his political ideals, the support by all the subjects who had been close was needed. The limitation of this research is the fact that the research had been proceeded with limited to the translations, among the many old writings related to Jeongjo. With the accumulation of the excavations of the new thoughts and of the results of the translations, the researches that are deeper will be needed.

  • This experiment was conducted to compare forage production and feed value of winter forage crops at the experimental field of Livestock Division, National Institute of Animal Science from 2003 to 2004 in Jeju. The experiment was arranged in slit plot design with three replications. Main plots consisted of two cutting times, one time cutting and two times cutting. Sub plots consisted of 5 different seed combinations, T1 (Italian ryegrass), T2 (Oat), T3 (Italian ryegrass 25+Oat 75%), T4 (Italian ryegrass 50+Oat 50%), T5 (Italian ryegrass 75+Oat 25%). One time cutting showed the highest dry matter (DM) yield by 18,680 kg/ha. Tow times cutting showed the highest crude protein (CP) content by 11.97%. The all treatments have narrow range of total digestible nutrient (TDN) from 60.6% to 70.4%.

  • This experiment was conducted to compare forage production and feed value of winter forage crops at the experimental field of Livestock Division, National Institute of Subtropical Agriculture from 2007 to 2008. The experiment was arranged in a randomized block design with three replications. The five winter forage crops used in this experiment were barely ('Youngyang' and 'Yuyeon'), oats ('Samhan' and 'Swan'), wheat ('Kumkang' and 'Woori'), triticale ('Shinyoung') and italian ryegrass ('Hwasan 101' and 'Florida-80'). The species having the fastest heading date was wheat (5th April) while the heading date of oats ('Samhan') was the latest as 28th April. The dry matter (DM) content of wheat was the highest among the five winter forage crops. Italian ryegrass ('Hwasan 101') showed the highest CP content by 11.2% and oats (Swan) showed the lowest content by 9.8%. Average acid detergent fiber (ADF) and neutral detergent fiber (NDF) content were 28.6 and 50.8% respectively. The five winter forage crops have narrow range of total nutrient digestibility (TDN) from 64.0% to 69.1%. Italian ryegrass ('Hwasan 101') showed the highest DM yield by 25,951 kg/ha, but the DM yield of barely and wheat low by 13,892 kg/ha ('Yuyeon') and 14,815 kg/ha ('Woori'), respectively. Italian ryegrass and oats have higher forage yield and feed value in Jeju. Also, oats has high grain and forage yield. The results demonstrated oats can cultivate as alternative winter forage crop for whole crop silage barely in Jeju.

  • As part of reconsideration on naming of the scenic site No.1 "Myeongju Cheonghak-dong Sogumgang," this study attempts to identify whether there is any mistake with reference to place naming of Korea's No.1 scenic site and if so, to correct the problem by examining the origin of the name and its transition progress through analysis and interpretation of old maps, ancient documents such as traditional geographic books, Yusangi(遊山記) and Letters Carved on the Rocks. The findings of this study are as follows: In traditional geographic books, a term of 'Mt. Cheonghak(靑鶴山)' was first found from "SinjungDonggookyeojisungram(新增東國輿地勝覽)" and after a place name, 'Sogumgang(小金剛)' first appeared in "Yeojidoseo(輿地圖書)" in the middle of the 17th century, it was reproduced in "Jungsuimyeongji(增修臨瀛誌)", which was published in the early 20th century. However, as a result of analyzing old maps, the place name, Sogumgang cannot be found in any local or national map except place names such as Cheonghak-dong, Mt. Cheonghak and Temple Cheonghak. Even though 'Biseonam,' 'Cheonyudong,' 'Gyeongdam' and 'Mt. Cheonghak' appear in Yulgok's "Yucheonghaksangi(遊靑鶴山記)", any part in which 'Sogumgang' was referred is not found. Later, Cheonghak-dong Sogumgang seemed to had been called 'Mt. Cheonghak' or 'Cheonghak-dong(靑鶴洞)' for more than three centuries as seen in Lee Sun-il's "Godamilgo(孤潭逸稿)", Heo Geun's farewell records, Heo Mok's "Cheonghak-dong Guryongyeongi(靑鶴洞九龍淵記)", Yoon Sun-geo(尹宣擧)'s "Padongilgi(巴東日記)" and Lee Won-jo's letters and a poem composed by Gang Jae-hang in the middle of the 18th century is the only record in which the place name, 'Sogumgang' is shown. Meanwhile, 'Sogumgang' carved on Inung Rock(二能巖) in front of Temple Gumgang is presumed to be carved by Inunggyeoone(二能契員) in the 1870s or in 1930s, considering the size of each character, calligraphy, overall layout, wear extent and records in Jiriji. Therefore, no evidence can be found to say that each character of 'Sogumgang' was written by Yulgok because 'Sogumgang' has strong evidences of the origin of its place name. To sum up the findings stated above, since Yulgok's "Yucheonghaksangi", this place seems to have been referred as 'Mt. Cheonghak Cheonghak-dong' and as it is confirmed that the place name, 'Sogumgang' first appeared in "Ohyeongosijo(五言古時調)" of "Ibjaeseonsangyugo(立齋先生遺稿)" and "Yeojidoseo" in the middle of the 18th century, it can be inferred that the place name, Sogumgang had been partly mingled as an another name of Mt. Cheonghak. Therefore, even though it is difficult to say the existing place name has a significant problem, it is thought that it will be better to name 'Mt. Cheonghak Cheonghak-dong' rather than 'Cheonghak-dong Sogumgang' in order to stress on this place's traditional identity as a scenic site related to Yulgok. In addition, as confirmed in this study process, it is said that each character of place names, 'Mt. Cheonghak' and 'Gyeongdam(鏡潭)' and name 'Yoon Sun-geo' carved in Rock Sikdang stated in Yoon Sun-geo's "Padongilgi" in 1964 is a pledge showing the influence of "Yucheonghaksangi" as an ancient travel literature as well as a mark of the Giho school scholars' respect and spirit to honor Yulgok.

  • Two experiments were conducted to evaluate the effects of nitrogen (N) application level and regrowth period on the fatty acid (FA) concentration and forage production of tall fescue (Festuca arundinacea Schr.) and bermudagrass (Cynodon dactylon (L.) Pers.). N was applied at 0, 50 and 100 kg/ha, and swards were cut after regrowth periods (15d, 30d and 45d). Concentrations of Individual FA were determined by gas chromatography. FA composition of tall fescue contains a high proportion ($87{\sim}88%$) of total FA contents as palmitic (C16:0), linoleic (C18:2) and linolenic acid (C18:3). The FA composition was not affected by N application, but a longer regrowth period significantly (p<0.05) decreased the composition of linolenic acid (C18:3) and increased those of linoleic acid (C18:2). The FA composition of bermudagrass was not affected by N application, but a longer regrowth period significantly (p<0.001) decreased the composition of linoleic (C18:2) and linolenic acid (C18:3). Linoleic and linolenic acfd of tall fescue were higher than those of bermudagrass. Dry matter (DM) yield of bermudagrass was significantly (P<0.05) affected by N application level and regrowth period. DM yield was higher at high N application and was higher at longer regrowth period. The crude protein concentration was higher at high N application and was low at longer regrowth period. Application of nitrogen fertilizer Increases dry matter (DM) yield and crude protein (CP) content of bermudagrass. These studies demonstrate opportunities to affect the FA concentration and composition of FA in forage through management strategies, which could affect milk FA composition.

  • This study was carried out with a focus on the factor on the periodical space organization of Daebodan (大報壇: the altar of great recompense) in Changdeok Palace, which is significant in terms of political history in the late Chosun Dynasty, and consider the factors in the formation of the structural system through historical records and drawings. Daebodan has the ideology of righteousness to the Ming Dynasty which the hierarchy of the Joseon Dynasty. who felt the crisis of the domination order, imposed as a solution after the Manchu war of 1636. In addition, Daebodan was built by complex factors that entailed the self-esteem of the 'Joseon Centralism Ideology (朝鮮中華)' and the desire of the sacrificial rituals for Heaven that were imminent to the kings of Joseon. Superficially, Daebodan has the spatial organization of the Sajik (社稷) Altar and the placement of an annex building, but had the applied placement due to limited topography and access to the backyard. Furthermore, the lateral structure of Daebodan multiply accepted various factors of the nine step's stairs, the hight of five cheok (尺), the circumstance of two floors that were showed in the altar and platform with small fences and an imperial order including the internal form of Hwangjangbang (黃帳房). Moreover, the name of the alter came from 'the Jiaote Sheng Book of Rites(禮記 郊特牲)' representing 'the suburban sacrifice ritual for Heaven (郊天)', and it was built by not only combining the system of the Sajik Altar in the Joseon Dynasty and China but also avoiding 'excessive etiquette (僭禮).' The point is a remarkable feature shown by the structural system of Daebodan. Thus, it is considered that the 'Notion of Confucian-Cultural Succession (中華繼承意識)' and the desire of the sacrificial rituals for Heaven were expressed by the structure and form of altar. This study examined the process of the creation, expansion, decline and disposal of Daebodan in a chronological order, and found that the ruling ideology of the governing elite by the political and cultural background of the era at each transitional point was reflected in the spatial formation of the altar. On the other hand, as a result of performing a field survey to find the location in accordance with Daebodan in drawing materials, there remains items such as worked stones from Daebodan, precast pavers and fragments of proof tile discovered in the surrounding of tora vine (Actinidia arguta) which is a natural monument of Changdeok Palace. As such, verification through future excavation and investigation is required.
