Freshly harvested seed of Chinese milk vetch (Astragalus sinicus L.; CMV) was strongly dormant because of hardseedness. Seeds of freshly harvested germinated only 8% while clipping the seed coat completely overcome the innate dormancy, which indicates inhibition of germination of the seed is mainly due to seed coat (87%). The dormant (intact) hard seeds did not imbibe water whereas the non-dormant (clipped) seeds took up rapidly. In natural environment condition, the hard seed coat dormancy was broken only after 5 months after seed harvest. To break such a strong seed coat dormancy, the chemical and heat treatments were effective. Concentrated sulfuric acid was more effective than dry heat and hot water treatments. Hot water treatment improved germination but the germination percentage was less than 41%. Treatments increased germination due to its effect on the seed coat integrity. A scanning electron microscope reveled that disruption of seed coat layers and subsequent development of numerous crack in the hilum region of the seed and on the seed coat surface of concentrated sulfuric acid treatment and formation of cracks in the dry heat treatments, respectively, were observed in the seed coat surface, which served as water entry points.

The monofilament with 0.304mm of diameter was produced using a polybutylene succinate (PBS) resin, and a gill net was made by it. We investigated the impact of heat setting temperature on the mechanical properties, knot state and height of gill net. Heat treatment was carried out using the high pressure steam machine for 20 minutes at temperature of $55^{\circ}C$, $60^{\circ}C$, $70^{\circ}C$ and $75^{\circ}C$. Before heat treatment, the strength and elongation of PBS monofilament were estimated to be $48.1kg/mm^2$, 23.8% at unknot, $37.6kg/mm^2$, 18.8% at single knot, $26.6kg/mm^2$, 22.9% at double knot in dry condition, respectively. The strength and elongation of PBS monofilament with double knot were decreased as heat setting temperature increased, and the decreasing rate of strength was showed to be higher than that of elongation. It was not found any differences in strength and elongation of PBS monofilament yarn with double knot at the $65^{\circ}C$ and $70^{\circ}C$ of heat setting temperature by 5% significance of T-test, but there was a significant difference at the $70^{\circ}C$ and $75^{\circ}C$ of heat setting temperature. The net's height and length from leg to leg appeared no differences at the $70^{\circ}C$ and $75^{\circ}C$ of heat setting temperature. In results, it was investigated that the PBS monofilament gill net with the maximized physical properties could be manufactured at $70^{\circ}C$ of heat setting temperature using a high pressure steam machine for 20 minutes.

The aim of this work to determine the formation of lactulose during heat treatment process as a contribution to the estabilishment of limits of chemical indicators for different types of heat processed milk and analyze of lactulose for the reconstituted milk added samples. The HTST(75$\^{C}$/15s) and UHT(130$\^{C}$/2∼3s) treatment realized with a pilot plant and heat-treated samples were stroed at 4, 10, 30$\^{C}$ for 4 weeks. Changes in lactulose was evaluated at 7 days intervals. The other heat treatment was sealed in glass tube and heated at 75$\^{C}$ for 10 to 120s and heated at 130$\^{C}$ for 2 to 60s in a thermostatically controlled constant temperature bath of glycerol. The reconstituted milk was made with full fat dry milk that reconstituted with deionized water to 10% total solid, and was added to milk at 10, 20, 30% respectively. The samples processed with a HTST pilot plant showed that lactulose was contained at 1.47∼1.52mg/10()ml and 8.19 ∼8.32mg/100ml for UHT-treated samples. Changes in the lactulose content of heat-treated samples during storage at 4 and 10$\^{C}$ for 4 weeks caused a slight increase, however a noticeable increase was observed at 30$\^{C}$ for 4 week. The glass tube samples showed that high correlations between relative increase in content of lactulose and increasing processing times(75$\^{C}$ : r = 0.986, 130$\^{C}$ : r = 0.987, respectively). Added with reconstituted milk would cause a increase of the lactulose content linear with increasing addition amount(r = 0.982). This results observed for lactulose in commercial milk samples would applied to the detection of chemical changes during heat treatment and illegal use of reconstituted milk.

The purpose of this study was to find the way of treatment and prevention the stroke by Sasang constitutional medical therapy. I came to get some conclusions after considering literatures of ${\ll}$Dongyi Suse Bowon${\gg}$ and the conclusion as follows. 1. In ${\ll}$Dongyi Suse Bowon${\gg}$ the stroke of Soumin is caused by 'Interior cold disease'. When 'Interior Yin' can not descend, the disease arise. In this case Lee Je-ma used 'Sohabhyang-won(蘇合香元)', 'Chulaek-su(鐵液水)'. 2. The stroke of Soyangin is caused by 'Interior heat disease'. When the hot Qi of stomach and spleen is blocked, the disease arise. In this case Lee Je-ma used 'Dokhwal-jihwang-tang(獨活地黃湯)', 'Jihwang-baekho-tang(地黃白虎湯)'. 3. The stroke of Taeumin is caused by 'Dry and heat disease'. When the heat of liver and the dryness of lung is excessive, the disease arise. In this case Lee Je-ma treated with 'Woohwang-chungsim-hwan(牛黃淸心丸)', 'Wonji-sukchangpo-tang(遠志石菖蒲湯)', and 'Kwache-san(瓜帶散)' etc. Above results indicate that not only taking medicine but also filling up the Healthy energy(保命之主) is important to treat stroke.

To examine the storage effect of the dry cured cultured undaria pinnetifida, its components were researched according to different places and periods of production and in heat treatment of it, how the different time, temperature and salt concentration can effect on its storage was researched as follows. In Pohang and Yeosu districts the most suitable period of processing was around the end of December and in Wando district, around the end of January. When it was heat-treated separately at $90^{\circ}C\;and\;100^{\circ}C$ there of occurred the comparative low increase of organic acids and volatile acids, and the slight decrease of pigment. When it was heat-treated in sea water and satuarated NaCl solution, the obvious change was not found in all components, and in fresh water organic acids and volatile acids were conspicuously increased. When it was heat-treated according to the different heating time (long or short), there was no remarkable change in all components, but when heat-treated for 20 sec. the decrease of carotenoid was conspicuous. When heat-treated for 40 sec. separately at $90^{\circ}C\;and\;100^{\circ}C$ in sea water, better effect for storage was resulted.
