This experiment was conducted to investigate the soil temperature. the characteristics of seedling growth and drought resistance of Job's tears under different seeding depth. The changes of soil temperature were similar to the patterns of atmosphere temperature. and the minimum and maximum temperature of the day were at 08: 00 and 16: 00 hours, respectively, and this was 1 hour late compared to the atmospheric temperature. In mean temperature under different soil depth, 3cm and 4cm soil depth were the same as $27.3^{\circ}C$ which was higher than that at 1cm and 2cm soil depth. Percentage of emergence was 81.2% at 4cm soil depth in Yulmoo 1 ho and 88.0% at 3cm soil depth in Yunchon 9 ho, respectively. Days to emergence after seeding was shortest at 1cm seeding depth as about 9 days and was 2 to 3 days later at other soil depth of 2, 3, 4cm compared to 1cm soil depth plot. Plant height and dry matter weight was highest at 3cm soil depth in Yulmoo 1 ho and at 4cm soil depth in Yunchon 9 ho. In the drought conditions, percent of survived plant was highest at 4cm soil depth plot of both varieties as 51.3% and 60.0%, respectively. In the drought conditions, soil depth was positively correlated with % of emergence, days to emergence after seeding, plant height, and dry matter weight per plant.

This study investigated the changes in physicochemical characteristics after 120 days of aging Korean red pepper paste, 'Kochujang', made of minor cereals in substitution for glutinous rice which has been conventionally used as starch source. The cereals used were waxy job's tears, proso millet, sorghum, barley and foxtail millet, Glutinous rice with barley was used as controls. The items determined were water activity, pH, content of amino nitrogen, chromaticity and sensory test. 1. The water activities(Aw) of Kochujang samples were in range of $0.72{\sim}0.82$ at the beginning of fermentation, with Aw barley paste bing the lowest, and Aw of sorghum paste bing the highest. Then Aw were slowly decreased to the range of $0.49{\sim}0.50$ during 120 days of fermentation 2. The pH of the pastes was in range of $4.94{\sim}5.02$ at the initial time of fermentation, and decreased steadily to 4.32{\sim}4.73 at the end. 3. The content of amino nitrogen was in range of $330.9{\sim}340.7\;mg%$ at the early time of fermentation. The highest content, $351{\sim}381\;mg%$, was observed at the 90th day of aging of glutinous rice paste, 105th day of job's tears paste, 75th day each of barley and proso millet, and 60th day each of sorghum and foxtail millet. 4. The Hunter tristimulus values (L, a, b) of all pastes were gradually decreased during fermentation. The value of barley paste was lowest among the pastes. 5. The texture of barley paste in sensory test showed significant difference with other pastes, whereas there were no differences in color, odor, taste and sensory qualities.

Dietary intake of whole grains, vegetable and fruit is known to reduce the degenerative chronic diseases, such as cancer and cardiovascular diseases. Antioxidative and antimutagenic effects of the ethanol extract of Korean Millet, Buckwheat, Sorghum and Job's tears were examined by inhibition against iron-induced linoleate per-oxidation, DPPH (1,l-diphenyl-2-picrylhydrazyl) radical generation and MDA-BSA (malondialdehyde-bovine serum albumin) conjugation, and Ames test using Salmonella. Buckwheat showed the strongest antioxidative effect in three different systems among these four grains, but it showed the lowest antimutagenic effect. Sorghum was the second to Buckwheat in iron-induced linoleate peroxidation inhibition activity and DPPH radical scavenging activity, and showed very good direct-antimutagenic effect in 2-Nitrofluorene treated Salmonella Typhimurium TA98 and indirect-antimutagenic effect in 2-Anthramine treated Salmonella Typhimurium TA98 and TA100 with hepatic S9 mixture. Millet showed the strongest antimutagenic effect in Salmonella Typhimurium TA98 and TA 100 with or without S9. Buckwheat contained the highest total flavonoids and polyphenols, 1.14 mg/g and 3.71 mg/g, respectively. Total flavonoid content in these four grains was negatively correlated with $IC_{50}$/ for DPPH radical scavenging antioxidative effect significantly (r=-0.9924, p=0.0076), but not with antimutagenic effect.

The purpose of this study is to explore types of postpartum depression and to understand the nature and structure of the postpartum depression by using Q-methodological approach. As a way of research, 55 statements concerning postpartum depression were selected through individual interviews with postpartum mothers and literature review. 30 women were chosen as a subject group for the study, with opinions shown in 55 statements divided into 9 scales by forced distribution. PC QUANL Program was used for analysis and Q-factors were analyzed by using principal component analysis. As a result, postpartum depression experience was classified into 5 types. There are "Role-Strain Type", "Unattributional Depression Type", "Psychosomatic Symptoms Type", "Self-Compassion Type", and "Role-Crisis Type". Type I was named "Role-Strain Type", referring to the strain generally experienced by mothers with regard to the new role as a mother and as a social member. Type II was named "Unattributional Depression Type", referring to the symptom experienced by people who were in a state of vanity and a sense of loss. They often break into tears for no specific reasons. In case of Type III, people in a state of "Psychosomatic Symptoms Type" develop physical symptoms after suffering from inherent emotional conflict. Type IV was named "Self-Compassion Type" refers to the symptom shown by those who feel pity for their children and for themselves. And they show inability to cope with the reality properly. Type V was named "Role -Crisis Type", which is experienced by people who have a burden and a severe fear of their own job and their children in their mind, also showing serious conflict with maternal role. Futhermore, it was carried out to examine structure of postpartum depression in terms of degree of depression and adjustment ability. Type I showed mild degree of depression and relatively good adjustment ability. Type II showed broad range of degree in depression and moderate adjustment ability. Type III showed moderate depression and relatively low adjustment ability. Type IV revealed relatively serious degree of depression and the lowest adjustment ability. Type V revealed very serious degree of depression and the lowest adjustment ability. As a result, considering the structure of postpartum depression. Type I is considered to be a normal depression sympton which most mothers generally experience, followed by Type II, Type III, Type IV and Type V, each of which show increasingly worse degree of depression and lower adjustment ability. In conclusion, it seems to be it is necessary to understand distinct symptoms of postpartum depression and to examine the characteristics and structure of those types, so that it could lead to more individual nursing approach.cteristics and structure of those types, so that it could lead to more individual nursing approach.

The perfect state of Bipolaris coicis, causing leaf blight of Job's tears, was in duced under in vitro conditions. Eighty nine isolates of the fungus were collected from 17 locations in Korea from 1994 to 1996. They were crossed on Sach's nutrient agar, on which a piece of rice straw was placed, and incubated at $25^{\circ}C$. Pseudothecia were produced only by certain combinations of compatible isolates. Although pseudothecia were usually produced on rice straw two weeks after incubation, asci and ascospores were observed only in a few pseudothecia examined. The pseudothecia were black and globose with protruding ostiolar beaks. The locules were filled with a mass of hyaline and filamentous pseudoparaphyses. Asci were cylindrical to clavate and straight or slightly curved. The ascus wall was bitunicate with short stipes. Ascospores were filiform, hyaline, and arranged parallel to slightly coiled in the asci, measuring $143-166.4{\times}2.6-3.8\;{\mu}m$. Perfect state of the fungus was identified as Cochliobolus nisikadoi (Tsuda, Ueyama & Nishihara Alcorn), based on the morphological characteristics.
