This study was carried out to get infirmation for the breeding varieties and developing the cultural methods with representative 32 cultivars which were diffused from 1900 to 1982 and two cultural methods which were old one i.e., low dressing and late planting and modern one i.e., medium dressing and early planting. Duration of transplanting between cultural practices were 15 days but the duration of heading date were 5days. Panicle projecting duration was 5-10 days in all cultivars, especially, it is 5 days in early maturing varieties, 6-7 days in medium maturing varieties and 7-10 days in late maturing varieties. Periods from transplanting date to effective ripening date were 99.8 days in low dressing and late planting method, 106.2 days in modern one but the periods from heading date to effective ripening date were 31.4 days in low dressing and late planting method, 30.2 days in modern one. Ripening speed was very active from 5 to 10 days after heading and the daily increase of 1000 grain weight was from 847.8mg to 1130mg in that time and it slightly increased from 5 to 35 days after heading in Japonica varieties but increased after heading and suddenly decreased at 30 days after heading in Indica/Japonica varieties. Meteorological factors (temperature and amount of solar radiation) were positively correlated with the ripening speed but negatively correlated with the period of physiological and effentive ripening.

In this study, we have investigated the antibacterial, antioxidant, and antitumor activities of mycelium cultural extract from mushroom. Mushroom mycelium was grown in a synthetic liquid media such as PD broth, YM broth or citrus extracts. In antibacterial activity test, the best result was achieved when mycelium cultural extracts from Phellinus linteus and Coriolus versicolor were incubated together on YM broth. On the other hand, mushroom mycelium cultured on citrus extracts showed better activity than that on PD broth. We have also tested the antioxidant activity at concentration up to 10 mg of mycelium cultural extract/mL. The more it is in higher concentration, the more the activity increases. The higher antioxidant activity was observed both on PD broth containing the Phellinus linteus and Coriolus versicolor mycelium and citrus extract containing the same. The complex culture extracts obtained from the synthetic medium and citrus extract medium showed 10-89% of the 1,1-diphenyl-2-picrylhydrazyl radical scavenger activity. The antitumor activity of mycelium cultural extract was examined by using MTT assay on A549 cells. Mushroom mycelium cultured on citrus extracts showed interestingly higher antitumor activity than that on synthetic liquid media.

The Seosan Geomenyeo(black submerged rocks), once located at the Cheonsuman bay of Buseokmyeon in Seosan, Korea, is a reef rock now exposed on the land surface. The Geomenyeo can also be found in the ancient geographic maps around the area. The local geographic names, like Buseok and Buseoksa temple are derived from the Geomenyeo. It is composed of ultramafic rocks complex and intrusive felsic igneous rocks. These rocks show diverse facies with various petrographic characteristics caused by geological processes such as intrusion and alteration. Ultramafic rocks complex can be roughly categorized as coarse grained ultramafic rocks and medium grained mafic rocks. Both cases are composed of pyroxene and amphibole, showing the general rock facies of pyroxenite, diabase and lamprophyre. Felsic igneous rocks includes pinkish medium grained granite, porphyritic amphibole granite and aplite with varied mineral compositions. The Geomenyeo is the only ultramafic rocks complex in the Cheonsuman Bay; moreover, it has a distinctive geological and scenic value, as well as a symbolic property. In order to preserve the Geomenyeo, it is necessary to investigate and promote it as a designated heritage site through academic studies, and compensate for the convenience and protection facilities. Additionally, the Geomenyeo should be evaluated as a maritime heritage site, due to the unique local culture as it succeeds the recognition of forefathers which regarded it as a local scenic site with significance.

To set efficient transformation system in chrysanthemum, thirty-four chrysanthemum (Dendranthema grandiflorum Kitamura) varieties were collected and cultured for shoot regeneration. Five varieties, ‘Shuho-no-chikara', ‘Zinba', ‘Baekma', ‘Pink pride' and ‘Keumsu' of them were selected, because they had a high shoot regeneration efficiency. MS medium containing 1.0 mg/L NAA and BA respectively was very adequate for shoot regeneration in those varieties. MS medium with 3.0 mg/L NAA and 1.0 mg/L kinetin in ‘Shuho-no-chikara' and the medium with 0.5 mg/L NAA and 3.0 mg/L BA in ‘Keumsu' were also suitable for shoot regeneration. The most efficient callus induction and shoot regeneration were obtained on MS medium. Shoot regeneration was enhanced more than 8% on MS medium with 0.3% phytagel and 10-15 mg/L putrescine. The best cultural material for shoot regeneration was stem. When stem was used as a culture material, shoot regeneration rate was increased more than 26% and the days to shoot regeneration was shortened about 14 days.

Agrocybe aegerita is Hymenomycetes fungus belonging to the order Agaricales and family of Bolbitiaceae. Much less is known about liquid culture of Agrocybe aegerita. Thus, the present study was to investigate the liquid cultural characteristics of Agrocybe aegerita my-celium. The optimal medium for the mycelial growth and density was ME medium, optimal tem-perature and initial pH were 25$\pm$1$^{\circ}C$ and 5.5, respectively. And optimal culture time for mycelial growth was 12 days. The modified optimal medium compositions were dextrin 3% (w/v), yeast extract 2% (w/w), MgSO$_4$0.05% (w/v), and KH$_2$PO$_4$0.15% (w/v). Under optimal culture conditions, the mycelial growth of modified optimal medium was higher than that of ME medium.

A good mycelial growth of F. fraxinea was observed on CDA medium. The optimum temperature and pH for the mycelial growth of F. fraxinea was at $30^{\circ}C$ and pH 6.0, respectively. Glucose was found to be the best carbon source and arginine was favored as nitrogen source. When the basal medium was supplemented with organic acids, the best growth was shown in succinic acid and the poor growth was shown in oxalic acid. Thiamine.HCl showed the best results on the growth of this fungus on basal medium. Mycelial growth of F. fraxinea was quite good when oak tree sawdust was used to cultural substrates. The best mycelial growth was observed when 20% of rice bran was added as a supplement on sawdust substrates. Higher yield of F. fraxinea was observed on the medium with oak tree and acacia sawdust.

To obtain basic data for mass production of Isaria japonica, cultural characteristics of japonica were investigated by using liquid, solid media and silkworms pupa. Mycelia grew favorably at the temperature of $23{\sim}28^{\circ}C$ on MYG medium with pH 7.0. The fruiting-body of I. japonica was induced below $20^{\circ}C$ in MYG liquid medium (Malt yeast glucose) under fluorescent light. In MYG basal medium mixed with pupal powder of silkworms, the fresh weight of fruiting-bodies was increased with increasing concentration of pupal powder. The highest yield of fruiting bodies was obtained in carbon-rich medium supplemented with pupal powder of silkworm. Also, fruiting-bodies of I. japonica were produced massively on the silkworm pupa placed on the stainless tray in the shortest time. The structure and shape of fruiting-bodies were coral-like, many-branched types with numerous conidiospores.

The character design is part of a culture. That is, it is not just an object but it reflects the cultural tendency and context where it is visualized. It's potential as a cultural medium of communication become pervasive in the field. One of good sources of characters is the classics which represent the nation's culture and history. The topic of this presentation is to show how a character in the Buddhist story, the Monkey King, designed differently in different context. For the purpose, the animation on the Monkey King in China, Japan and Korea are reviewed and analyzed. The result shows that the same animation character has been designed in different way in different context and it reflects the cultural tendency of the country. For example, Koreans tend to emphasize the global feature of the character. In case of Chinese, however, the character designer emphasizes traditional value. Finally, the designer in Japan tries to put their cultural element in detailed part of the character that makes it appeal to the public.
