This study was conducted to examine the water absorption, water-holding capacity, color and mineral contents in natural and cultured dried sea mustards on soaking treatment. Four dried samples of natural and cultured sea mustards were used for the experiments. The effects of soaking treatment on water absorption and water-holding capacity in sea mustards were examined, as the results, these were rapidly accelerated 5 minutes after soaking. It showed that water-holding capacity was significantly high in the case of high absorption of water by soaking. The L, a and b values were increased until 30 minutes after soaking. There was significant difference for potassium content between dried natural and dried cultured sea mustards and the natural sea mustard was 10 times as high as the cultured sample. All mineral elements in these materials were significantly decreased and especially, potassium were significantly more decreased at 50~80% of total content by soaking treatment. Ca/ P ratio in these materials by soaking was about 2~3 : 1 levels.

Immunopotentiating activity of water extract of Lycii Fructus, Rubus Fructus, Torilis Fructus, Schizandrae Fructus and Cuscutae Semen were investigated using mouse fed with normal diet and protein deficient diet. Body weight, ratio of spleen or thymus to body weight, number of total peritoneal exudate cell, content of total serum protein and albumin content were decreased in the mouse fed with protein deficient diets as compared to the mouse fed with normal diet. Regardless of the nutritional condition, the supplement of the water extract of Lycii, Rubus Torilis, Schizandrae Fructus or Cuscutae Semen increased the ratio of spleen to body weight. The increment of this ratio was significant by the supplement of water extracts of Lycii and Torilis Fructus in mouse fed with protein deficient diet. The supplement of water extracts of Torilis Fructus to the mouse fed with protein deficient diet increased the content of total serum protein and albumin content significantly. Similar results were obtained with Lycii, Rubus, Schizandrae Fructus and Cuscutae Similar. The electrophorogram shows the difference in the concentration of some serum protein constituents between the mouse fed with normal diet and protein deficient diet.

Degradation behaviors of filament-winded composites have been evaluated under the accelerated environmental test of high temperature, water immersion and thermal impact conditions. Two kinds of laminated composites coated by an urethane resin have been used: carbon-fiber reinforced epoxy(T700/Epon-826, CFRP) and glass-fiber reinforced phenolic (E-glass/phenolic, GFRP). For tensile strength of $0^{\circ}$ composites, CFRP showed little degradation while GFRP did high reduction by 25% under the influence of high temperature and water However for water-immersed $90^{\circ}$ composites tensile strength of both CFRP and GFRP showed high reduction. Bending strength and modulus of $90^{\circ}$ composites were largely reduced in water-immersion as well as high temperature environment. Urethane coating on the composite surface improved the bending properties by 20%, however hardly showed such improvement for water-immersed $90^{\circ}$ composites. In case of shear strength and modulus, both CFRP and GFRP showed high reduction by water-Immersion test but did a slight increase by high temperature and thermal impact conditions.

Dansam, the root of Salvia miltiorrhiza Bge, (Labiatae), has a bitter taste and a slightly 'cold' property, and is nontoxic. In the present study, effect of Dansam on nitric oxide (NO) generation from peritoneal macrophags was examined. Dansam had no effect on NO generation by itself, whereas recombinant interferon-${\gamma}\;(rIFN-{\gamma})$ alone had modest activity. When Dansam was used in combination with $rIFN-{\gamma}$, there was a marked cooperative induction of NO generation in a dose-dependent manner, The optimal effect of Dansam on NO generation was shown at 6 hr after treatment with $rIFN-{\gamma}$. Furthermore, the effect of Dansam was mainly dependent on Dansam-induced tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ secretion. These results suggest that Dansam induces NO generation from macrophages by the result of Dansam-induced $TNF-{\alpha}$ secretion.

Water-soaked spots or lesions were observed on fruits or stems of melon plants at house-melon farms in Andong, Korea. The symptoms developed to soft rot of the fruits of wilting of the whole plants. The causal organism isolated from the water-soaked le-sions was identified as Erwinia carotovora subsp. carotovora based on the morphological and physiological characteristics. The causal bacterium was susceptible to not only two kinds of medical antibiotics but also two kinds of agrochemicals tested. Since the bacterial soft rot is a first described bacterial disease in melon in Korea, we propose to name the disease as "bacterial soft rot of melon".

This investigation was undertaken for me purpose of studying me sensory and textural properties of Julpyun (Korean traditional rice cake) made by various soaking time (1, 4, 6, 8, and 12 hours) of rice during storage at room temperature. The storage periods were 2, 4, 6, and 10 hours. Sensory evaluation was done by a panel of 12 judges majoring in food and nutrition. The luation was repeated 3 times. Objective evaluation was done by rheometer and color difference meter. As a result of me sensory evaluation for Julpyun made by various soaking time and storage periods, mere were significant differences (p<0.001) in most of characteristics between soaking time and storage periods. Julpyun made by soaking time for 12 hours showed the most favorite tendency during storage periods. The result of textural properties measured by rheometer showed similar trend to those of sensory evaluation. By me color difference meter, L (lightness) value were increased by increasing the soaking time. There were significant differences (p<0.001) between me samples.

The changes in gelatinization patterns of potato were investigated while steeping in water for 7 days at 30${\pm}$1$^{\circ}C$. The transmittance of 0.1% starch suspension was increased rapidly from 60$^{\circ}C$ in raw starch and the starch steeped for 2 days, and increased rapidly from 65$^{\circ}C$ in the starch steeped for 4 and 6 days. As the steeping period increased, the transmittance was decreased at above condition. The gelatinization temperature of the starch measured by differential scanning calorimetry was increased from 62.79$^{\circ}C$ to 63.72$^{\circ}C$ as the steeping period increased. The gelatinization enthalpy reached the maximum in the starch steeped for 4 days. By amylograph, the initial gelatinization temperature was increased from 66$^{\circ}C$ to 84$^{\circ}C$ as the steeping period increased. Peak viscosity was decreased during steeping and the starch steeped for 5 days had no peak viscosity. Peak height after cooling to 50$^{\circ}C$ was increased up to the 4th day and began to decrease. As the steeping period increased, there was much loss of birefringence at higher temperature. The crystallinity by X-ray diffraction disappeared from 65$^{\circ}C$.

Weathered soil slope loses its shear strength if it is exposed in the air for a long time or in contact with water. And this kind of strength loss is remarkable in dam slope which has very big difference in water level according to the season. In this study, shear strength loss of weathered soil due to saturation had been found out through dryness and wetness repetition direct shear test. Also relation between penetration blow number(Nc) and shear strength parameter had been found out through small sized dynamic cone penetration test device and the correlation equation of Nc had been proposed through artificial neural network analysis to estimate shear strength parameter easily.

In order to study for the production techniques and the materials of using in Korean Lacquer Antiques, we examined the section structure by SEM and Microscope, the qualitative analysis of lacquer layer by XRF and XRD, the qualitative analysis of Golhae layer by XRF and XRD, the qualitative analysis of Golhae by EDS on the locquer-wares which was excavated from Anapchi Pond Site in Kyungju and Miruksa Temple Site in Iksan. In the lacquer-wares excavated from Anapchi Pond Site, the lacuqer-wares layers made by a cloth attached on the surface of wooden vessel and Golhae-a mixture of clay and lacquer-covered on the cloth and finally finished with the red lacqure, being mixed with pure mercury sulfide(HgS) and lacquer. And raw materials of Golhae made of clay. The lacquer-wares excavated from Miruksa Temple Site in Iksan, we presumed that the lacquer-wares used fine born grains in place of clay for the raw materials of Golhae. Expecially in case of black lacquer-tray, we found that lacquer put on the surface of wooden vessel without cloth attaching and Golhae covering and the production of wooden vessel was used power-driven machine.
