The food quality of lupin seed, i.e. soaking, cooking, sprout growing and mold growing for fermentation, was investigated by using the seed of Lupinus angustifolius harvested in Western Australia. A method to produce lupin seed protein concentrate (LPC) was developed, and the wage of LPC in Korean food system was investigated. The water soaking rate of lupin seed was faster than that of soybean, but the cooking rate of lupin seed was much slower compared to soybean. The thermal softening time, $D_{100}$, was 345 min for lupin seed and 84 min for soybean. A two-phase solvent extraction system consisting of haxane-alcohol-water could effectively remove the residual bitter taste, lipid and yellow pigments of lupin seed flour, and the resulting LPC contained over 50% protein and had bland flavor and milky white color. Treatment of LPC with carbohydrate decomposing enzymes resulted in a product of more soluble and higher concentration of protein. Methods to produce lupin seed vegetable milk and lactic beverages from LPC products were discussed.

As the result of implementing a treated material test and durability test after quickly drying S.P.F. species, a type of softwood structural material, within a short period time, soaking it in liquid phosphate flame proof agent for an hour, microwave heating it, and compressing it from 3.8cm to 1cm, when setting the appropriate heating time of microwave heating at 7 minutes at 5kW, it is observed that it satisfies the target water content (4~5%). It is shown that in a water content measurement of the wood that is compressed after being softened by soaking in the flame proof agent, drying and heating at 3kW for 9 minutes, all specimens satisfied 12~14%, the appropriate water content for exterior wood. Also, it is shown that in terms of the flame performance obtained through a flame resistance treatment of the compressed wood and a treated material test, the specimen soaked in flame proof agent for 30 minutes was the most excellent, and that the performance test result of the compressed wood in all areas, such as nail withdrawal resistance, compression, bending strength, and shearing strength, were all improved in their mechanical features to twice to three times better performances.

This study was to explain the properties of acorn sediments and characteristics in the texture of acorn mooks due to the differences in preparing conditions of acorn sediments. The hardness of mook increased at 4$^{\circ}C$ during storage. The increase rate of acorn mook's hardness after storage for 24 hrs at 4$^{\circ}C$ were higher than those of others. X-ray diffraction of the retrograded acorn mooks was little different during storage at 4$^{\circ}C$. The syneresis of acorn mook was decreased with increasing the soaking treatment. The syneresis (%) of nontreated sample (0-0) was larger than those of the others.

$Ca^{++}$ content and histochemical changes during processing Mooks prepared with sea mustard (Undaria pinnatifida) and sea tangle (Laminaria japonica) were studied. $Ca^{++}$ content of sea mustard Mook during gelation in $CaCl_2$ solution was not only increased fast, but also decreased fast during soaking in distilled water as comparing with that of sea tangle Mook. Both solubilization of the seaweeds by 1 % $K_2HPO_4$ and filtration of solubilized seaweed were decreased the extruding amount of $Ca^{++}$ from Mooks during soaking. The cell walls in sea mustard were likely irregular and ling, but those in sea tangle were regular and round shape. alginic acid was mainly occurred around cell walls. The alginic acid was gradually solubilized depending on heating and alkali treatment. Thus, the fillament cells in sea tangle were cut finely during processing Mook, while those in sea mustard were remained tolerably.

1) An experiment was made at the newly constructed glass house of Chun chan Agriculture callege to find out facts about the late-raising of Cortinellus edodes (Berk) Ido et Imai during the winter season. 2) The host timbers used in this experiment were Quercus Serrata Thumb and Quercus crispulo BI.; 5 years old each, the diameter ranging from 6cm to 17cm, dividing them into 12 diameter groups with 10 timbers in each group. The total number of timbess was 240 in two blocks. 3) As the pre-treatment of host timber, the autumn generation in 1962 was inhibited, and before being put into the glass-house, they were stimulated of generation for 3 days after 3 days, water-soaking. 4) The temperature control was made by using two coal stoves and the humidity control by spraying and two full water tanks. During cloudy weather and night, the green house was covered to preserue constant temperature of $5^{\circ}C{\sim}10^{\circ}C$. 5) The result; Quercus Serrata Thumb. with lesser diameter than 9cm showed no generation either in as big timber as one with diameter 11 cm. On the other hand, too big timbers showed low rate of generation; the reason, at a guess, is the too short period of cultivation and insufficient water soaking and inappropriate temperature. 6) The most standard size of host timber was found out be those with diameter 12cm~15cm in Quercus serrata Thumb, and those with diameter 14cm~17cm in Quercus crispula BI. Quercus crispula seemed to have slightly greater efficiency of generation than Quercus Serrata Thumb., but it could not be concluded as "decisive". Lastly, the host timber used in this experiment were old and the rate of generation was low as a whole.

This study aimed to determine the effects of cooking treatment on chromaticity and 6 mineral contents (calcium, phosphorus, magnesium, iron, sodium and potassium) in sea mustards. Four samples of natural and cultured sea mustard were used for the experiments. Each sample was treated with four cooking methods (A: soaked in water, B: boiled in hot water, C: saute and boiled in hot water, D: seasoned with vinegar). The L, a and b values were the highest on boiling, and the lowest on seasoning with vinegar. The a value of cultured sea mustard was higher than the natural one by cooking. Moisture was highest boiling and were ordered as saute and boiling, soaking and seasoning with vinegar. Calcium, iron, magnesium and phosphorus contents were remarkably decreased by seasoning with vinegar. Boiling treatment made less decrease than saut and boiling in these mineral contents. The solubilities of mineral in soup water were recognized therefore, it indicated that soup water was a good source of minerals as it applies to cooking, from the view point of science of cookery. Sodium and potassium contents decreased significantly more at 68% and 85% of total content on basic soaking treatment. Ca/P ratio was about 1∼3 : 1 in cultured sea mustard and 3∼4 : 1 levels in natural one.

This study was carried out to investigate changes in epigallocatechin gallate (EGCG) contents and antioxidant activity of duck egg after pressurized soaking in green tea extract. The duck eggs were soaked in different concentrations of green tea extract (10~30%) and subjected to pressures of 0.1~5.0 MPa for 30 min at ambient temperature in a lab model high-pressure rig. After pressured treatment at 5.0 MPa in 30% green tea extract, EGCG content of duck egg white (20 mg/100 g) markedly increased compared to that of untreated sample (0.17 mg/100 g). Moreover, the antioxidant, hepato-protective, and cellular antioxidant activities of duck egg white after pressured treatment at 5 MPa in 30% green tea extract were all higher than those of untreated sample. Our results could have a direct impact on duck egg consumption by increasing consumer awareness of the health benefits of duck eggs.

This research was performed to develop mass propagation method of Alpine modest primrose (Primula modesta var. hannasanensis T.Yamaz.) for improving the conservation and utilization of the species. Seeds were collected on August 2011 in Jeju-city and well-selected seeds were dry-stored at $4{\pm}1.0^{\circ}C$. Seed size ranged $0.44{\pm}0.07{\times}0.61{\pm}0.04mm$, and weight of 1,000 seeds was $51.78{\pm}0.021mg$. Thus the seed was classified as 'dwarf seeds'. As the result of dormancy characteristics, moisture content of freshly matured seeds increased rapidly by water-soaking treatment and seeds did not germinate at $20^{\circ}C$ for 4 weeks under the light condition. Therefore, seeds were estimated to have physiological dormancy. Germination conditions of dry-stored seeds were found to be $20^{\circ}C$ and light condition, and seeds did not germinated under dark condition regardless of all temperature regimes. Therefore, Alpine modest primrose seed was considered as photoblastic type. Percent germination (PG) and germination energy (GE) were greatly improved by soaking the seeds in $GA_3$ and kinetin for 24 hours. Especially, 200~500 mg/L $GA_3$ treatment resulted in the highest PG (95.5%) and GE (98.3%). So, chemical treatment such as $GA_3$ was thought to be a useful method for raising seedling uniformly.

This study was conducted to know the effect of storage period, harvesting time and light condition on dormancy breaking of major weeds. Echinochloa crus-galli, Cyperus serotinus, Aeschynomene indica, Ludwigia prostrata and Bidens tripartita had the 10 or 30% germination ability within 30 days after harvest but scirpus juncoides, Potamogeton distinctus, Aneilema japonica and Monochoria vaginalis had not germination untill 120 days after harvest of seed. C. serotinus and P. hydropiper required strong light for germination but S. juncoides, L. prostrata and B. tripartita showed the less tham 5% germination in the dark condition gerntinator. S. juncoides germination showed negative response in chemical soaking but A. japonica, B. tripartita and L. prostrata showed high germination percentage in Acetone, Chloroform and distilled water soaking during the 10 days after treatment.
