Noerok is a green pigment made of mineral used the Gachil(priming coat) of wooden architecture in Chosun Dynasty era. It has been reported that various Noerok are discovered in Janggimyeon, Pohang. In this study, The Noerok from two places is compared and discussed. Noerok in the two places has blulsh-green to green color, and it is similar to their occurrences on fracture filling, vein and dike on outcrop. However, there are differences between two sites according to its petrological feature, mineral composition and geochemistry. While the Noeseongsan sample is mostly celadonite, Gwangjeongsan samples are characterized by celadonite with varying contents of cristobalite, tridymite, feldspar, along with some vitrified contents. In terms of major elements, the amount of $Al_2O_3$, $Fe_2O_3$, MgO and $K_2O$ decreases linearly with increasing $SiO_2$, whereas $Fe_2O_3$ is linearly proportional to MgO. In summary, Noerok in the study areas can be classified into 4 types (type 1, type 2, type 3-1, type 3-2) base on color, mineral composition, elemental composition, and vitrification grade.

This study was conducted to obtain fundamental information on forage sorghum breeding in forage crop field of Livestock Experiment Station at Suwon from 1986 to 1991. The charcterization of sorghum germplasm was performed through 1986 to 1987, and after parental lines were selected from diverse sorghum germplasm on the basis of flowering date, plant height and several morphological characters for forage sorghum Fl hybrids. The range of variation of 50% flowering date and plant height were greater in order of forage sorghum sudangrass and male sterile line of grain sorghum. The average flowering date was earlier in sudangrass and male sterile line of grain sorghum than forage sorghum lines from the tested sorghum germplasms. And the average plant height was tall in order of forage sorghum, sudangrass and male sterile lines of grain sorghum. There were remarkable morphological variations between sudangrass lines and male sterile lines of grain sorghum such as plant color, leaf midrib color, glume color, seed coat color, head compactness and shape, awns, grain covering and 100 seed weight.

The purpose of this study was to provide basic information for breeding cowpeas (Vigna unguiculata L.) by investigating the crop characteristics of 245 accessions of cowpea collected in Korea and abroad. All specimens flowered within 41 to 50 days (51.5%) or 51 to 60 days (43.7%) of sowing and matured 21 to 30 days (53.9%) or 31 to 40 days (23.7%) from flowering. Thus, the total time from sowing to maturity was either 71 to 80 days (26.9%) or 81 to 90 days (23.4%) for all specimens. The accessions were classified into indeterminate type (72.7%), intermediate type (25.7%) and determinate type (1.6%) based on growth; prostrate type (78.8%) and erect type (21.2%) based on plant type; heart shape (98.4%) and lanceolate (1.6%) based on leaflet shape; and purple (85.2%), white (13.6%) and light green (1.2%) based on corolla color. The accessions were classified into brown (54.7%) and yellowish brown (37.6%) based on color at pod maturity; and downward (90.6%), middle (5.7%) and standing upright (3.7%) based on pod setting position. Seed coat color varied as 25.3% were brown, 23.3% were black, and 20.8% were white. Seed shape also varied as 66.9% were egg-shaped, 24.9% were rectangular and 8.2% were kidney-shaped. Pod lengths ranged from 10.1-20.0 cm and from 20.1-30.0 cm in 89.0% and 8.6% of specimens, respectively. There were 12.1-15.0, 9.1-12.0, and 15.1-18.0 seeds per pod in 62.0%, 25.7% and 9.1% of specimens, respectively. The weight of one hundred seeds ranged from 15.1-20.0 g (37.6%) and 10.1-15.0 g (28.6%). Seed yields per plant were 100.1-200.0 g (52.7%), less than 100 g (22.9%), and 200.1-300.0 g (15.9%). The starch content in the seeds of the seven selected resources ranged from 44.1 to 57.0% while the protein content ranged from 23.3 to 27.5% with significant differences. The sucrose content ranged from 1.46 to 2.03%, also with significant differences.

This study was carried out to assess the variation of saponin contents in 293 Korean native soybean landraces reintroduced from USA to Korea in 2007. Group A saponin content ranged from 149.8 ${\mu}g\;g^{-1}$ to 1279.0 ${\mu}g\;g^{-1}$ with an average of 484.9 ${\mu}g\;g^{-1}$. Group B saponin content ranged from 2160.1 ${\mu}g\;g^{-1}$ to 7868.6 ${\mu}g\;g^{-1}$ with an average of 3670.0 ${\mu}g\;g^{-1}$. Total saponin content including both group A and B contents ranged from 2502.8 to 8764.0 ${\mu}g\;g^{-1}$ with an average of 4154.9 ${\mu}g\;g^{-1}$. Five promising landraces for use as breeding materials that showed higher than any other landraces in group B and total saponin content were IT226841, IT226761, IT226841, IT226828 and IT228534. IT226841 showed the highest saponin content with group B content of 7868.5 ${\mu}g\;g^{-1}$ and total saponin content of 8764.0 ${\mu}g\;g^{-1}$ among landraces. In the relationship among each components, group A saponin content showed a positive correlation with group B saponin content (r=0.3708) and total saponin content (r=0.5119). Group B saponin content showed a very high positive correlation (r=0.9876) with total saponin content. When landraces were compared for the total saponin content based on collected location, landraces from North Korea showed the highest, Gyeonggi-do showed second highest content, followed by Chungcheongbuk-do, Gangwon-do, Gyongsangbuk-do, Chungcheongnam-do, Gyongsangnam-do, Jeollabuk-do and Jeollanam-do. Landraces were also grouped according to seed size and seed coat color. Small seed group was higher than medium and large seed groups that showed no significant difference in total saponin content. Seed coat colors showed no significant difference in total saponin content.

The 117 soybeans seeds were collected from the nine provinces of Korea, and protein and lipid contents, and fatty acid composition levels were evaluated to investigate their relationship. The 100-seed weights of the black soybeans were varied $27.7{\sim}33.1g$, while the 100-seed weight of yellow soybeans were varied $24.6{\sim}36.6g$. Protein and lipid content of the 117 soybean seeds was 38.3% and 17.8%, respectively Protein contents of the 59 black soybean seeds (38.6%) were significantly higher than those of the 58 yellow soybean seeds (37.9%). However, lipid contents of the black soybean seeds (17.6%) were lower than those of the yellow soybean seeds (18.1%). Linoleic and oleic acid composition levels of the 117 soybean seeds were 53.75% and 22.08%. Unsaturated fatty acid levels of soybean seeds showed a statistically significant variability among the nine provinces of Korea, however, the differences were not found in the linoleic (18:2) and oleic acid (18:1) levels. Therefore, it was considered that the significant variability of unsaturated fatty acid were mainly due to the variations of linolenic acid (18:3) level. The composition levels of linoleic, oleic, palmitic (16:0), and linolenic acid in the yellow soybean seeds were 53.43%, 22.73%, 12.23%, and 8.24%, while those of the black soybean seeds were 54.13%, 21.48%, 12.47%, and 8.31%. Obtained results suggested that fatty acid composition levels were varied and possibly influence by the phenotype of seed coat colors. Oleic acid, mono-saturated fatty acid, showed the most remarkable variability between yellow and black soybean seeds, and the composition levels were higher in the yellow soybean seeds. Relationship between unsaturated fatty acid levels and 100-seed weights in the yellow soybean seeds showed a negative correlation (r=-0.513, P<0.01), but no relationship $(r=0.154^{ns})$ was observed in the black soybean seeds.

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.
