Cereals were used as solid-substrate for the cultivation of Ganoderma lucidum. The hydration time with cold water appeared to be 10, 11 and 12 hours for Malt, Danyeob and Black soybeans respectively, and the water content was enough for mycelial growth in this condition. The hydration times required for sorghum, job's tears, barley, brown rice and wheat were 2.5, 4, 5, 10 and 12 hours respectively, but the final water content was much less than optimum water content (65%). Hot water reduced the hydration time of soybeans, and the water content reached to 65% within $120{\sim}150$mins. This condition showed the optimum for the mycelial growth. For the other cereals, it took about $17{\sim}120$ mins to reach the optimum water content (65%). From this result, hot water was better than cold water for the hydration of cereals. We attempted to develop a practically applicable process by combining the soaking and sterilization. This process was successful with soybean and about 1.1 times of water based on the weight of soybean appeared to be suitable. In all varieties of cereal, the water content of 65% appeared to be the best for the growth of the fungi and production of glucosamine related to the amount of mycelium. The mycelial growth rate in accordance with kinds of solid-state materials was in the order of barley > wheat > job's tears > sorghum > brown rice > soybean. The glucosamine content for determing the mycelial growth in solid material was in the order of wheat> barley > brown rice > job's tears > sorghum > soybean.

This experiment was conducted to investigate the effect of nitrogen fertilization in job's tears (Coix lachryma-jobi L.) on the growth characteristics, grain yield, nitrogen accumulation, and chemical property of soil after harvest. Heading and budding stages were shorter than control but growth periods was increased because of the increase of ripening periods according to the increase of nitrogen fertilizer applications. Number of main culm node and culm diameter was similar but culm length and tiller number per plant were better according to the increment of nitrogen fertilizer applications than control but the decrease of grain yield was attributed to the fact that damage by corn borer was 30% in $240kg\;ha^{-1}$ of nitrogen treatment. Some of yield components was better according to the increment of nitrogen fertilizer applications but grain number per plant of $160kg\;ha^{-1}$ of nitrogen treatment was greater. So grain yield was the highest ($3,410kg\;ha^{-1}$) at the $160kg\;ha^{-1}$ of nitrogen fertilization. Nitrogen use efficiency decreased according to the increase of nitrogen fertilization. Total nitrogen of soil after experiment in 0, $80kg\;ha^{-1}$ of nitrogen treatments was lower and in 160, $240kg\;ha^{-1}$ of nitrogen treatments was higher than that before the experiment.

The properties of various grains used for the solid-state cultivation of basidiomycetes were examined. The hydration time with cold water was 10 hours for malt soybean. The required hydration time for Job's tears, barley and wheat was 4, 6 and 12 hours, respectively, but the final moisture content ranged from 30 to 48 %, which was much less than the optimum moisture content for mycelial growth. For the mass cultivation of mycelia, the hydrated grains with cold water were placed in plastic bottles. The mycelial growth ra in e bottled grains was high in the early stage with inoculation of homogenized mycelium. The mycelium activity was maintained by adding sterilized water in the middle of the cultivation period. Jupjang underwent sensory evaluation to examine the possibility of utilizing basidiomycetes in functional foods. The grains fermented with Ganoderma lucidum was the best for Jupjang. The combination of malt soybean and Job's tears was the best for Jupjang. The acceptability of Jupjang was improved during the period of aging time.

This study was performed to examine the mineral binding properties of total dietary fiber (TDF) and acid detergent fiber (ADF) from Job's tears (Yulmoo: Coix lachryma-jobi L. var. Ma-yuen Stapf.) bran. The endogenous Ca and Fe contents of dietary fiber extracted from Yulmoo bran were measured by atomic absorption spectrophotometer (AAS). Ca contents were 40, 118.6$\mu\textrm{g}$ Ca/g TDF and 131.6 $\mu\textrm{g}$ Ca/g ADF. Fe contents were 1,219.7 $\mu\textrm{g}$ Fe/g TDF and 277.5 $\mu\textrm{g}$ Fe/g ADF. The calcium binding capacities of dietary fiber at pH 5.0, 6.0, 7.0 were 50.77, 77.57, 86.64% for TDF, 40.27, 51.42, 40.90% for ADF, respectively. The iron binding capacity of dietary fiber at pH 5.0~7.0 was 95~97% for TDF and 85~95% for ADF.

To find out the optimum fertilizer levcl for Job's Tears, Seungju local cultivar, experiment with six fertilizer levels was conducted on the experimental field of forage crop in Sunchon National University from Apr. 1989 to Aug. 1990. The results obtained were summarized as follows: I .Raising nitrogen(N) application rate up to 13.5 kg/lOa increased dry matter yield linearly. However, at high N application rate, 18 kg/lOa, plants were too leafy and parts of leaves and lodging were decreased. so that dry matter yield was decreased.2. The optimum application rate of fertilizers turned out to be 13.5-6-6 kg/lOa of $P_2O_5$, $K_2O$. Content of crude protein, yield of fresh and dry matter were the highest and that of crude fiber such as NDF. ADF and cellulose were the lowest at this rate.

This study was carried out to select economic-crops according to the improvement methods of newly-reclaimed soils. Silage corn, soybean, Job's tears and sweet potato were cultivated under 6 treatments including integrated improvement plot, control plot, compost plot, subsoiling plot, phosphate plot and lime plot on the Songjeong loam from 1985 to 1988. Crop yields and soil physical properties were investigated throughout the experiment. Soil porosity in the sweet potato plots were highest. In case of cultivated years, those of 4th year were lowest. Averaged yield increasing ratios of silage corn, soybean, job`s tears and sweet potato in the integrated improvement plots were 132%, 29%, 49% and 59%, respectively. And that of 5 soil improved treatments for 4 crops were 53%, 15%, 25% and 38%, respectively. After subtraction of the total expenses of soil conditioners, the economical efficiency of soil improvements were clear in the 4 crops except the compost plot of silage corn. That of sweet potato plot was the highest.

Sasang constitutional medicine is a Korean traditional medicine in which individuals are classified into four constitutional types, Taeyangin, Taeumin, Soyangin, and Soeumin. To develop new functional Saengsik products, we investigated the immunostimulatory activities of raw materials of Saengsik (milled rice, barley, Job's tears, soybean, adzuki bean, millet, eggplants, radish, carrot, Lentinus edodes, Agaricus bisporus, and Auricularia auricula-judae) and Saengsik products (Mix 1~6) in primary immune cells (lymphocytes and macrophages) isolated from blood of Taeumin, Soyangin, and Soeumin types. Increased cell proliferation as well as NO and TNF-${\alpha}$ protein production by immune cells treated with extracts of materials of Saengsik and Saengsik products were measured as immunostimulatory parameters. We chose milled rice, adzuki bean, radish, and Lentinus edodes to study the immunostimulatory activity of Teaumin, barley, soybean, eggplants, and Agaricus bisporus to study the immunostimulatory activity of Soyangin, as well as Job's tears, adzuki bean, carrot, and Auricularia auricula-judae to study the immunostimulatory activity of Soeumin. The mixtures (Mix 1~6) were made with different kinds and ratios of Saengsik materials based on the immunostimulatory activities of Saengsik materials. The immunostimulatory activity of Taeumin was highest in Mix 2 (rice 60%, adzuki bean 20%, radish 10%, and Lentinus edodes 10%) extract-treated immune cells among all six mixtures. The immunostimulatory activity of Soyangin responded best to Mix 4 (barley 60%, soybean 20%, eggplants 10%, and Agaricus bisporus 10%) among the six extracts (Mix 1~6). The increased immunostimulatory activity of Mix 6 (Job's tears 60%, adzuki bean 20%, carrot 10%, and Auricularia auricula-judae 10%)-treated immune cells was higher than the other five extracts (Mix 1~5). Accordingly, Mix 2, Mix 4, and Mix 6 may be useful as mixtures for Saengsik products having personalized immunostimulatory activities.

This study was performed to investigate the effects of Cheonggukjang added with Job's tears (CAJT) on antiobesity and lipid profiles on diet-induced obese rats. Male Sprague-Dawley rats were fed high-fat diet only (A, control), and high-fat diet with Cheonggukjang powder 10% (B), CAJT powder 10% (C), Cheonggukjang powder 20% (D), CAJT powder 20% (E) for 5 weeks. Body weight gains were similar in the experimental groups, but FER was significantly lower in the group E than group A (p<0.05), and adipose tissue weights in groups with Cheonggukjang and CAJT powder were similar to those in the group A. The lengths of small intestine were significantly longer in the groups B, C, D, and E than the group A (p<0.05). Hepatic concentrations of total cholesterol (TC) and triglyceride (TG) were similar to each other. Fecal weights were not significantly different among the groups. Fecal TC concentrations were similar in the experimental groups, but fecal TG concentrations were greatly increased in the groups B, D, and E (p<0.05). The serum TC, HDL-C and LDL-C levels varied slightly among the groups, but serum TG levels were decreased in the group D and E than in the group A (p<0.05). The AI and CRF were marginally decreased in the groups B, D, and E than in the group A (p<0.05). However, blood glucose levels were not significantly different among the groups. From the findings, it had shown that Job's tears Cheonggukjang could improve lipid profiles.
