This research is basic research about 「the afforestation project of the Shilla Dynasty's capital forest」 which is controlled by the research institute of forest and environment of Kyungbuk province. The results of the investigation about target places and selection of major species of trees is as follows. 1. In the Shilla Dynasty's times, the peach tree was the indicator of unusual changes in weather, and was also the symbol of unsurpassed beauty. Peach trees were so prevalent that people called the forest peach-hill or peach-forest. Therefore, the main tree of Shilla Dynasty's capital forest would have to be a peach tree. 2. From several records, pine and bamboo were planted or grown together. The pattern of planting trees like this case is also historic, so should be utilized positively. 3. In order to afforest the capital forest, the bamboos have to be planted on Nam-mountain in Kyung-ju, and maple trees have to be planted on Kumgang mountain. 4. There were many big trees during the Shilla Dynasty, and the name of one of the Six Main Villages was 'Big Tree Village'. Therefore, big and long-lived trees have to be planted also. 5. The willow tree has to be considered for afforesting the capital forest even though the willow trees are misunderstood to cause allergies. They are traditional landscape architecture trees. In the traditional literature, the willow tree stands for good news. 6. Japanese cornellian cherry(Cornus officinalis), which is related with old narrative literature in the era of King Kyungmun, has to be planted for the forest, and has to be considered to be an educational tree. 7. Korean Rhododendron, which is related with Madam Suro's story, has to be planted in stone gardens.8. Lotus, Korean pulsatilla, Boxwood, Bombycis Mulberry, and Japanese Apricot have been recorded just one time, but these are also important plants which have to be reflected on afforestation of capital forest project. 9. The forests of Shilla on the old records exist in 17 places. The afforestation project has to be undertaken at these places. 10. The people of Shilla deified the forest and trees, which were the places where ancestral rites had been performed. For example, Gyerim, Sinyurim, and Wanggasu were the sacred forests of the capital forest.

Bamboo is one of the major biomass resources that have many advantages such as fast growing, easy cultivation, short rotation, and a relatively lower price. In this study, the anatomical characteristics of Moso bamboo (Phyllostachys pubescens) by age from one-year-old to five-year-old were examined by optical and scanning electron microscopy. Also, the crystalline properties such as relative crystallinity and crystallite width were investigated by an X-ray diffraction method. In one-year-old bamboo xylem, a few vascular bundles showed missing bundle sheath in near the intercellular space. Moreover, one-year-old bamboo had the shortest fiber length and the smallest values in vessel diameter, width of vascular bundle, and thickness of inner layer. One-year-old bamboo also showed the smallest values in the crystallinity and crystallite width. Near epidermis samples had longer fiber length and greater vascular bundle spacing than near pith samples. Relative crystallinity and crystallite width near the epidermis were also higher than near the pith. This study revealed significant differences in qualitative and quantitative anatomical characteristics between one-year-old and two-year- or more old Moso bamboos. It is concluded that the structural differences by bamboo age can be used to differentiate the characteristics of juvenile and mature bamboo.

This study examines, based on the database of the Institute for the Translation of Korean Classics(ITKC), the garden plants and their symbolism, and the landscape culture recorded in 'Jipkyungjaeyoungsi(the Series of Poems on Gardens Poetry)' in relevance to traditional houses. First, Jipkyungjaeyoungsi had been continuously written since mid-Goryeo dynasty, when it was first brought in, until the late Joseon dynasty. It was mainly enjoyed by the upper class who chose the path of civil servants. 33 pieces of Jaeyoungsi(題詠詩) in 25 books out of a total of 165 books are related to residential gardens. The first person who wrote a poem in relation to this is believed to be Lee GyuBo(1168~1241) in the late Goryeo dynasty. He is believed to be the first person to contribute to the expansion of natural materials and the variation of entertainment in landscape culture with such books as 'Toesikjaepalyoung(退食齋八詠)', 'Gabeunjeungyukyoung(家盆中六詠)'and 'Gapoyukyoung(家圃六詠)'. Second, most of the poems used the names of the guesthouses. Out of the 33 sections, 19(57.5%) used 8 yeong(詠), then it was in the sequence of 4 yeong(詠), 6 yeong, 10 yeong, 14 yeong, 15 yeong, 16 yeong, 36 yeong(詠) and so on. In the poem writing, it appears to break the patterns of Sosangpalkyung(瀟湘八景) type of writings and is differentiated by (1) focusing on the independent title of the scenery, (2) combining the names of the place and landscape, (3) focusing on the name of the landscape. Third, the subtitles were derived from (1) mostly natural landscape focused on nature and garden plants(22 sections, 66.7%), (2) cultural landscape focused on landscape facilities such as guesthouses, ponds and pavilions(3 sections), (3) complex cultural scenery focused on the activities of people in nature(8 sections). Residents enjoy not only their aesthetic preferences and actual view, but the ideation of the scenery. Especially, they display attachment to and preference for vegetables and herbs, which had been neglected. Fourth, the percentage of deciduous tree population(17 species) rated higher(80.9%) compared to the evergreens(4 species). These aspects are similar results with the listed rate in 'Imwonkyungjaeji(林園經濟志)' by Seo YuGu [evergreen 18 species(21.2%) and deciduous trees 67 species(78.8%)] and precedent researches [Byun WooHyuk(1976), Jung DongOh(1977), Lee Sun(2006)]. Fifth, the frequency of the occurrence of garden plants were plum blossoms(14 times), bamboos(14 times), pine trees(11 times), lotus(11 times), chrysanthemum(10 times), willows(5 times), pomegranates(4 times), maple trees(14 times), royal foxglove trees, common crapemyrtle, chestnut trees, peony, plantains, reeds and a cockscombs(2 times). Thus, the frequency were higher with symbolic plants in relations to (1) Confucian norms(pine trees, oriental arbor vitae, plum blossoms, chrysanthemums, bamboos and lotus), (2) living philosophy of sustain-ability(chrysanthemum, willow), (3) the ideology of seclusion and seeking peace of mind(royal foxglove ree, bamboo). Sixth, it was possible to trace plants in the courtyard and outer garden, vegetable and herb garden. Many symbolic plants were introduced in the courtyard, and it became cultural landscape beyond aesthetic taste. In the vegetable and herb garden, vegetables, fruits and medicinal plants are apparently introduced for epigenetic use. The plants that were displayed to be observed and enjoyed were the sweet flag, pomegranate, daphne odora, chrysanthemum, bamboo, lotus and plum blossom. Seventh, it was possible to understand garden culture related to landscaping materials through poetic words such as pavilions, ponds, stream, flower pot, oddly shaped stones, backyard, orchard, herb garden, flower bed, chrysanthemum fence, boating, fishing, passing the glass around, feet bathing, flower blossom, forest of apricot trees, peach blossoms, stroking the pine tree, plum flower blossoming through the snow and frosted chrysanthemum.

Kwon Kisoo is one of the most promising artist in Korea. His paintings portray a lot of metaphors and philosophies in oriental art. As an artist, he adapts both oriental and contemporary ideas to make his paintings. His main motifs are Plum blossoms, Chrysanthemum, Orchid and Bamboos. These plants are known as 'Sa-gonja' in Korean but translated as the 'Four Gracious plants' or the 'Four Gentle Plants in english'. These noble plants represent the four seasons. They grow in different weather conditions. In oriental art, these plants are considered very important for their qualities. These qualities are important attributes for gentlemen in literati painting. The drawing of the 'Four Gracious Plants' in Kwon Kisoo's paintings is simplified. He uses lines, shapes and colour to create contours of the motifs. In his paintings, there is another icon he calls 'Dongguri'. Dongguri is the main character in Kwon Kisoo's paintings. It was developed in 2002 by fast brush strokes. Dongguri is an admired character because it looks like very cute in Kwon Kisoo's paintings. Dongguri is always seen living in the midst of the 'Four Gracious Plants'. The 'Four Gracious Plants' with other landscape features like rocks and mountains are places 'Dongguri' lives. Dongguri is also often found performing a lot of actions like climbing, running, sitting etc. All these actions depict metaphors which have been unraveled in this study.

The morphological characteristics of vascular bundle sheath occurring on the culm wall were investigated by using many species of Bambusa and Sasa in order to test new classification method for endomorphological charateristics of Bamboos. The results obtained were as follows. 1. As for the thickness of the culm wall in the culm, it was shown that the culm wall of the Bambusa becomes thinner in propertion to its nearness to the upper part of the tree, but no distinctive difference appeared in the Sasa. 2. It was shown that many species of Bambusa has a, b types but the Sasa had a' type and had a, b types. 3. It was shown that many species of Bambusa had e', h, and i types but the Sasa had not them and both of species had not f type. 4. It was shown that many species of Bambusa had c, d, e, and g types, but the Sasa had c, d, and e types and had not g type. 5. In the classification of Bambusa and Sasa, The method of the physiological classification was more effective than test of external observation, and it will encourage further study.

This study contemplates the utopian landscape recognized by the scholars with twenty three pieces of 'travel record'. Consequently, five key words - Mureungdowon(武陵桃源), Byeolcheonji(別天地), Dongcheon(洞天), Chonghakdong, Eungeoji(hermitage) - are chosen for comprehending the utopia and their landscape characteristics are organised as follows. Mureungdowon in Jirisan Mountain which the scholars dreamed of is a flatland with the full energy for local vegetation and domestic animals in the mysterious and deep gorge. This utopia eventually reflects the rural landscape. Byeolcheonji is a utopia combining the concept of a fairyland and beautiful scenery. The scholars also used the term 'Dongcheon' for naming the enclosed landform which is suitable for seclusion and defining the some areas of beautiful scenery. Cheonghakdong, which is set only in Jirisan Mountain, has been formed by the stone scenery of gorges and Buril waterfalls around the whole area of Burilam Hermitage, the vegetation scenery of pine trees and bamboos with the legend of Choi Chiwon and his engraved inscription on a rock. Adding to the utopia passed down, the scholars perceived the village with geographical features with back to the mountain and facing the water, the river practising the trade, the flatland enclosed by bamboo forests, the vegetation mainly consisting of fruit trees and beautiful scenery as the utopia realized on earth. It is equivalent to the world of human beings laboring appropriately and living in Mother Nature. As mentioned above, this study has significance for apprehending the relevance between the culture of strolling in the mountains by the scholars of Joseon Dynasty and the fairyland and explaining the various traditional utopias from the inherited concepts from China to the naturalized realistic utopia.

The antioxidant and anti-neuroinflammatory activities of water, 30, 70, and 100% ethanol extracts of leaves of three different species of bamboo (Phyllostachys nigra, P. bambusoides, and Sasa borealis) were investigated. The levels of total polyphenol and flavonoid were measured, and antioxidant activity was evaluated using various antioxidant assays (DPPH, ABTS, and FRAP). Lipopolysaccharide (LPS)-induced BV2 microglial cell activation was used to evaluate the anti-neuroinflammatory properties of the bamboo leaf extracts. Treatment with both aqueous and ethanolic extracts showed no cytotoxicity in BV-2 microglial cells. Pre-treatment of BV-2 cells with bamboo leaf extracts significantly inhibited LPS-induced excessive production of nitric oxide in a dose-dependent manner. Moreover, phytochemical analysis based on the extraction solvent showed that caffeic acid, p-coumaric acid, and tricin are the principal constituents of all three bamboo leaf extracts. Therefore, our findings suggest that bamboo leaf extract contains potent antioxidants and anti-neuroinflammatory compounds that can be used as potential therapeutic agents for the treat neuroinflammatory diseases.

Phyllostachys pubescens planted in the Nambu Forest Experiment station in Jinju city of Gyongnam province was used, to investigate the physical and mechanical property of bamboo in this study. The ages of the P. pubescens were 1, 2 and 3 years, respectively. This experiment was carried out in August and January. The P. pubescens were divided into upper, middle and lower parts according to the growing points. The physical and mechanical properties of the P. pubescens were investigated before and after treatment of hot water and microwave irradiation. 1. The upper part of the P. pubescens indicated the highest static MOE according to the growing points. The range of the static MOE was from 70,000 to 110,000kgf/cm². 2. When P. pubescens were treated with hot water of 95℃, the ratio of softening was about 10~30%. 3. As microwave irradiation time was increased, the MOE values was decreased in both green and water-saturated bamboos. For the irradiation time of 20 and 30 seconds, the static MOE of P. pubescens was decreased up to about 50% comparing with non-treated.

As to the up-lnd bamboos, I have reported, in my previous works, that Korea has two species in the genus of Pseudosasa, four in Pleioblastus, and other four in Sasa. In the present work, I dealt with Sasamorpha Purpurascens Nakai var. Borealis Nakai which proved the strongest vitality of all up-land bamboo yet found in various up-lands of Korea, and which might be most important from the utility view-point. This report is chiefly on its procreation. Sasamorpha Purpurascens Nakai var. Borealis Nakai can be found almost everywhere throughout the country, and its leaves and stems are much used in farms in various forms of manufacture. It is also welcomed as the feed for livestocks and as cover plants for aforestation, especially as the excellent means of errosion control on devastated hill sides. It is also widely accepted that it will provide, in the immediate future, abundant sources for the up-land bamboo pulp. As the first phase of my research plan on the subject, I undertook to determine the possible best way of its procreation, for which were included the experiments of inducing the growth of subterranean stems, the entire stand cutting, transplanting, reclaimed planting after burning etc. in order to observe the plant elongation, growing conditon, climatical effect etc. What has been fuond out so far given here as follows: 1) Of the various sections of the country, Mt. Odae area gives out the most excellent Sasamorpha Purpurascens Nakai var. Borealis Nakai(the leaf weight of which is 450 gr.) and Taekwanryong area comes the next class. This species can be transplanted anywhere in the South Korea. 2) The elongation of S.P. Nakai var. Borelais begins at around the middle of May and almost completely stops by the 20th of August. 3) The best studied transplanting season is supposed to be Feb. -April, for those transplanted during that period proved 100% of success. The next best transplanting season may be October. Rain fall does not have so much effect on transplanting as the growing season does. 4) In inducing the subterranean stems, the growing season can be ignored. The root expnsion is most animated during the months of April-June, the most active season for water absorption. Those stems induced during the winter proves more rapid growth. 5) The entire stand cutting shows greater growth than the reclaimed planting after burning and that, the growth is most vigorous during May-July, whereas during the hottest months of Aug-Sept. the growth shows only 5 cm. The new shoots grow slower both in the field of entire stand cutting and in the field of reclaimed planting after burning than in the otherwise fields.
