This study was conducted to determine changes in th contents and composition of dietary fiber during the growth of soybean sprout. Soybean was soaked in water at $25^{\circ}C$ for 2hrs and cultivated at 2$0^{\circ}C$ for 7 days under dark condition. The soybean sprouts were divided into cotyledon and axis and sampled every 24hrs. The analysis methodlogies used were Van Soest's NDF, AOAC's ADF and lignin and Prosky's IDF, SDF, TDF. The weight of 100 sprouts increased gradually from 20.26g to 90.12g during the growth periods. The weight increased to 344.9% of the original weight. The germination rate was 100% after soaking at $25^{\circ}C$ for 2hrs. Root length increased gradualy from 0.6cm at 1st day to 17.2cm at 7th day. The crude ash and crude fat contents showed no significant change in the cotyledon and axis. The crude protein contents increased in the cotyledon and axis, whereas the total carbohydrate content didn't have general tendency. The insoluble dietary fiber(IDF), soluble dietary fiber(SDF) and total dietary fiber(TDF) contents of cotyledon were no significantly different from 20.01%, 1.45%, 21.46% at 1st day to 22.75%, 2.07%, 24.82% at 7th day on dry basis. In axis those contents increased from 23.19%, 1.97%, 25.16% at 1st day to 32.78%, 3.02%, 35.80% at 7th day, respectively. The neutral detergent fiber(NDF) contents of cotyledon and axis increased from 4.35% to 6.39% and from 6.44% to 26.60% respectively on dry basis. The acid detergent fiber (ADF) contents of cotyledon and axis increased from 2.84% to 4.91% and from 2.5% to 4.7%, but there were no significantly different in the hemicellulose and lignin contents on dry basis. The hemicellulose and lignin contents of axis increased with culture periods from 1.70% to 4.41% and from 0.20% to 2.11%, respectively. The cellulose contents increased from 4.54% to 20.35% on dry basis.

Factors affecting the survival of out planted Cryptomena and Japaneses Cypress seedlings. (I) - Especially on the drying and water soaking duration ­ There are often the cases of poor survival percentage for the economic forest establishments of Cryplomeria japonica D. Don. and Chamaecyparis obtusa End. This study was carried out to investigate the survival factors of both 1-1 seedlings and Cryptomena cutting Seedlings by room drying conditions, day drying conditions, OED green water soaking treatment and drying duration at the forest nursery of Chonnam National University from February to September. 1979. The results are as follows: 1. From 11 a.m. to 3 p.m. fluctuation in then moisture contents(MC) rapidly decreased and M.C. fluctuation in indoor until 5 p.m. showed the same results with the amount of an hour fluctuation in outdoor. 2. M.C. fluctuations between OED green and non-treatment of these seedlings were silghtly different. 3. The survival percentage of OED green and non-treatment of seedlings were highly significant in the room drying conditions and the day drying conditions respectively The effects of water soaking treatment on rooting was negligible. The survival percentage of seedlings of OED green was higher than that of non-treatment. 4. Although survival percentage of Japanese Cypress was almost in accord with Cryptomena, the power of resistance to drying was lower m Japanese Cypress than m Cryptomeria. 5. Compared with Cryptomena seedlings the survival percentage of Cryptomeria cutting seedlings was higher and not influenced at all in case of being drying for two hours; but it was highly significant in interactions between the drying time and the water soaking time. 6. When Cryptomena and Japanese Cypress seedling become drying in indoor for four days, the survival percentage remarkably reduced after two days and also was highly significant among numbers of drying days.

The objective of this study was to identify the effect of zebularine soaking on the early growth stage of barley (Hordeum vulgare L.). Hence, root elongation was measured daily according to the different concentrations of zebularine (1.0, 2.5, 5.0, and 10.0 μM) for 4 days. On the first day, root length at 2.5 and 5.0 μM was significantly longer than that in the non-treated control. On the second day, root length was not significantly different among all concentrations and controls. On the third day, root elongation was suppressed by the effect of zebularine, except at 2.5 μM. The treatment time of zebularine accounted for the largest proportion of the variation in root elongation. After transplanting, plant growth velocity was similar to that of the control; however, plants at 2.5 μM showed faster growth velocity than that of the other concentrations and the control. In the metaphase of mitosis, most chromosomes of cells under zebularine treatment were ordinary regardless of the concentration, while some cells with short chromosomes were investigated at around 2%. The short chromosome showed a centromere. In addition, it showed short and long arms based on the centromere. The lengths of the short and long arms were different for each short chromosome. It is necessary to study the effect of the short chromosome as a chromosomal function on plant growth and phenotype through investigation of meiosis and fertilization at the chromosome level.

The alkali solution consisting of 5% NaOH, 5% NaCl, 2% Tea is most suitable for making pidan. During the soaking period, the values of pH increased from pH 9.02~ 9.19 to pH 12 in the egg white and increased from PH 6.1 to PH 11.63 in the egg yolk. Quail's egg jelled on the 7th day of immersion and the hen's egg and duck's egg jelled on the 10th day of immersion. The Quail's egg ripened at $25^{\circ}C$ in 30~35 days, and Sunghua crystals were formed at the end of the ripening period The moisture content of pidans decreased by 3.5~4.0%, but relatively crude protein, crude fat and crude ash increased by 1.0%, 1.9% and twice respectively. The content of Ca in the hen's pidan and quail's pidan increased about 40%, that of K in the duck's pidan increased about 13% and that of Mg in the hen's pidan and duck's pidan increased about 23~28%. The content of Na in the 3 groups all increased approximately 7 times. The content of total cholesterol level in pidan yolks decreased by 21~40% in each pidan. As a result of a sensory evaluation, the white hen's pidan was most agreeable in flavor and the quail's pidan was most agreeable.

The infant seedling of rice(8-to 10-day-old) has often suffered from submergence just after transplanting due to the too short seedling height, 5 to 8cm, This experiment was conducted to elucidate the effect of gibberellic acid($GA_3 : 25% soluble liquid) with the application methods of foliar spray and seed-soaking on the elongation of seedling height of infant rice seedling in machine transplanting, We used a japonica rice variety, Hwaseongbyeo, and the seeding rate was 200g per seed tray(30$\times60$\times3cm). Generally,$GA_3 and Metalaxyl increased the elongation of seedling height of infant seedling while Tetracycle decreased the seedling height, To increase the seedling height of infant seedling, the foliar spary application of $GA_3 was better than seed-soaking treatment. The optimum concentration of $GA_3 for the foliar spray was about l0ppm and the optimum application time of $GA_3 was 3 to 4 days after sowing.

In order to study the catch situation of the octopus pot fishery in the coastal waters of Gangneung, catch quantities and weight per month and depth, the soaking time & loss of fishing gear were studied based on 62 fishing times (1 set consisted of 150 pots which is equivalent to 1 fishing time) over a period of 10 months from February to December 2003 using commercial fishing vessels and training ships. The monthly CPUE was generally high in the months of june - September, and during this period July showed the highest quantity (134g/pot, 19.21kg/haul). In consideration of the fact that octopus below the weight of 2kg is protected in foreign countries, the majority of the catch was small with 76% (486 octopuses) below 1kg. The octopus catch quantity was high in depth of more than 40m, and the average catch number per set of pots in depths of over 50m was the highest with 13 octopuses. CPUE(g/pot) was the highest at a depth of over 60m recording 101. In terms of catch quantity per soaking time (4-18 days) the highest was on the 7th day, and 13-18 days also recorded high catches, and this suggests the possibility of ghost - fishing with the loss of fishing gear. Loss of fishing gear was the highest in terms of loss frequency and amount at depths of 20-30m. Consequently, it seems that octopus pot fishing at depths of more than 30m would relieve friction with other types of fishing and increase fishing efficiency.

Shelf-life of soybean curd prepared with ozone-treated soybeans investigated on pH, acidity, sour taste, slime formation during storage at 3$0^{\circ}C$. Total Plate counts of raw soybeans showed about log 7.0 CFU/g before ozone treatment. The sterilization efficiency of raw soybeans showed the most effective in 0.5ppm of aqueous ozone treatment at 4$^{\circ}C$ for 90 minutes. Raw soybeans were treated with ozone by different methods; (1) Ozone treatment for 90 + 90 minutes (first 3.5~5 hours and later 8.5~10 hours) of 10 hours during soaking in aqueous solutions at 4$^{\circ}C$ (OW). (2) Ozone treatment by exposure first to 30ppm of gaseous ozone for 90 minutes and then allied to OW method (GO+OW). The log reduction of raw soybeans treated by OW and GO+OW methods showed 3.72 and 4.15, respectively. Soybean curd prepared with OW and GO+OW-treated soybeans kept the shelf-life of 4 and 5.5 days at 3$0^{\circ}C$, respectively, but, that without ozone treatment spoiled at me day.
