This study is to examine the origin of Andong sikhe and to introduce the making process of it. The following facts are found after consulting literature and doing field-work to find out the origin of Andong sikhe. Andong sikhe is a kind of so-sikhe develolped as a sweet beverage, the making process of which is to ferment the mixture of boiled rice, radish slices, and red pepper extract with malt liquid. So-sikhe is made by fermenting with malt the mixture of boiled rice, radish slices, red pepper powder and flavorings such as a shallot, a garlic and salt, and o-sikhe is made by adding fish to the ingredients used to make so-sikhe. So-sikhe is distributed on the coastal areas of the East Sea and the inland areas adjacent to them as o-sikhe is. It is presumed that so-sikhe was introduced to Korea by the same way as o-sikhe was introduced eastward from the regions around Thailand by sea. It is also presumed that Andong sikhe has been developed into its present type after the second half of the 18th century when red pepper was introduced to Korea and then widely used.

This study was carried out to obtain basic data for selecting the applicable crops in reclaimed land and to provide guidelines for the rotation between paddy and upland cropping. Field experiment was conducted with six summer crops(garland chrysanthemum, young radish, small radish, kale, lettuce, red lettuce) at Dae-Ho reclaimed experiment plots in Dangjin province. Dry weights and plant heights of harvested crops were measured and soil chemical properties were analyzed. Plant height and dry weight decreased significantly with increasing soil saturation paste extract electrical conductivity(ECe) and sodium adsorption ratio(SAR). The threshold ECe of salt inhibition for six crops was less than $1dS\;m^{-1}$ for young radish and kale, greater than $4dS\;m^{-1}$ for garland chrysanthemum, and greater than $6dS\;m^{-1}$ for small radish, lettuce, and red lettuce. At higher ECe that inhibits crop growth, with every increase in $1dS\;m^{-1}$, dry weight index decreased by 3.35 for kale, 3.92 for small radish, 3.98 for young radish, 4.66 for lettuce, 7.57 for garland chrysanthemum, and 8.45% for red lettuce, respectively. The ECe causing 50% reduction of dry weight index was $18.9dS\;m^{-1}$ for small radish, $17.3dS\;m^{-1}$ for lettuce, $15.4dS\;m^{-1}$ for kale, $12.0dS\;m^{-1}$ for red lettuce, $11.3dS\;m^{-1}$ for young radish, and $11.0dS\;m^{-1}$ for garland chrysanthemum. Among the tested 6 summer crops through field experiment and in-situ survey, kale was proved to be a favorable vegetable crop at reclaimed tidal land.

The antibacterial effects of seed decontamination during presoaking before sprouting as an intervention step for eliminating foodborne pathogens on red radish seeds were evaluated. The effect of seed decontamination on seed germination rate was also evaluated. Red radish seeds were inoculated (at a level of 3 to 4 log CFU/g) with Listeria monocytogenes ATCC 19111 and decontaminated with 20,000 ppm calcium hypochlorite, 50 and 100 ppm chlorinated water, acidic electrolyzed water, low-alkaline electrolyzed water, and ozonated water for 6 hours. The control seeds were immersed in distilled water. The germination rate was measured on each treatment for 48 hours. Treatments with 20,000 ppm calcium hypochlorite, acidic and low-alkaline electrolyzed water were more effective than treatments with chlorinated water and ozonated water. Immersion in 20,000 ppm calcium hypochlorite resulted in the largest microbial reduction (more than 3 logs). Treatments with acidic and low-alkaline electrolyzed water reduced APC by 3 logs and L. monocytogenes counts by 2 logs. After sprouting, APC and L. monocytogenes counts on seeds treated with 20,000 ppm calcium hypochlorite, acidic and low-alkaline electrolyzed water were significantly lower than the control. The germination rate ranged from 93.5% to 97.7% except for 20,000 ppm calcium hypochlorite (from 82.3% to 84.8%) after 48 hours. Although the treatments tested in this study will not eliminate L. monocytogenes on inoculated red radish seeds, the results show that rapid growth of surviving cells during sprouting could be prevented if red radish seeds are given a presoak treatment used in combination with a disinfectant treatment of irrigation water.

Recently, as consumers' interest and importance in health care have significantly increased, they prefer natural and organic foods that do not use chemical pesticides. Since sprout vegetables effectively promote health and prevent diseases such as cancer and cardiovascular disease, the consumption of sprout vegetables, a highly functional and safe food, has been increased significantly. This study aimed to investigate the effect of light on the growth and bioactive compounds of seven different sprout vegetables. After sowing the seeds of various sprout vegetables (kale, Chinese kale, broccoli, red cabbage, alfalfa, red radish, and radish), the sprouts were cultivated under light conditions (20℃, RGB 6:1:3, 130 μmol·m^-2·s^-1, 12 hours photoperiod) and dark condition for 7 days. Sprouts samples were taken at 1-day intervals from 4 to 7 days after treatment. The fresh weight, dry weight, plant height, total phenol content, and antioxidant capacity were measured. Brassica species (kale, Chinese kale, broccoli, red cabbage) and Medicago species (alfalfa) had significantly higher fresh weight values under dark conditions, while the content of bioactive compounds was increased considerably under light conditions. In contrast, the fresh weight of Raphanus genus (red radish, radish) significantly increased under the light condition, but the antioxidant phenolic compounds were significantly higher under the dark state. A negative correlation was observed between the growth and secondary metabolites in various sprout vegetables. This study confirmed the effect of light and dark conditions on different sprout vegetables' growth and nutritional value and emphasizes the importance of harvest time in producing high-quality sprout vegetables.

Three types of veterinary antibiotics, including oxytetracycline (OTC) and chlortetracycline (CTC) of tetracycline class and amoxicillin (AMX) of penicilline class, were artificially introduced into the irrigation water. The residue of veterinary antibiotics in the soil, the absorption-translocation of veterinary antibiotics into the red lettuce and young radish plant, and crops yield were investigated according to the agricultural water irrigation method (surface drip irrigation, underground drip irrigation, and sprinkler irrigation). There was no significant difference in the residue and translocation of veterinary antibiotics in the soils and crops according to the irrigation method and type of veterinary antibiotics (p>0.05). For the edible parts of red lettuce and young radish, all three types of veterinary antibiotics were found to be below the detection limit, indicating that the safety of the crops was secured. The translocation factor of red lettuce and young radish were found to be less than 0.3 and 0.2, respectively. However, continuous introduction of veterinary antibiotics in agricultural arable lands may have negative effects by affecting soil microbial activity and soil microbe species diversity, so continuous management is deemed necessary.

This study was performed to investigate the effects of dry powders, ethanol extracts and juices of radish and onion on lipid metabolism, lipid peroxidation and antioxidative enzyme activity in rats. Forty-nine male Sprague-Dawley rats weighing 157$\pm$6g were blocked into seven groups according to body weight and raised for four weeks with diets containing 5%(w/w) dry powders of two different vegetables consumed frequently by Korean-radish(Raphanus sativus L.) and onion(Allium cepa L.), ethanol extracts and juices from equal amount of each dry powder. All the powders, ethanol extracts and juices of radish and onion decreased total lipids, triglycerides and total cholesterol concentrations in plasma and liver. Above all, onion ethanol extract decreased them most remarkably. It was thought that organosulfur compounds and flavonoids extracted from onion by ethanol inhibited biosynthesis and absorption of lipid and promoted degradation of lipid. Radish powder also decreased them by increasing fecal excretions of total lipids, triglycerides and total cholesterol most effectively. Catalase and glutathine peroxidase(GSH-px) activities in red blood cell(RBC) were most remarkably increased by radish powder and onion powder respectively. Superoxide dismutase(SOD), catalase and GSH-px activities in liver were most remarkably increased by onion ethanol extract, radish powder and onion ethanol extract respectively. Xanthine oxidase(XOD) activities in liver were most effectively decreased by ethanol extracts of radish and onion. Thiobarbituric acid reactive substance (TBARS) levels in plasma and liver of experimental groups were significantly lower than those of controls. Above all, onion powder decreased them most effectively. It was thought that vitamin E and high flavonoids in onion powder inhibited lipid peroxidation, promoting liver and RBC SOD, catalase and GSH-px activities and inhibiting XOD activities effectively. Flavonoids in onion ethanol extract inhibited lipid peroxidation, promoting three antioxident enzyme activities and inhibiting XOD activities most remarkably. Also flavonoids and high vitamin C in radish powder inhibited lipid peroxidation, promoting liver and RBC catalase most remarkably and inhibiting XOD activities. In conclusion, radish and onion were effective in lowering lipid levels and inhibiting of lipid peroxidation in animal tissue. From these data, radish and onion can be recommended in the treatment and prevention of diseases such as cardiovascular disease and cancer and in delaying aging. As ethanol from onion were most effective in lowering lipid level and promoting three antioxident enzymes, and inhibited lipid peroxidation as did we should try to utilize onion skin which is discarded though reported to have abundant flavonoids.

Physicochemical properties and sensory characteristics of kakdugi prepared with red pepper powder gamma-irradiated up to 7 kGy were determined during fermentation at 5℃. The overall fermentation patterns between kakdugies with irradiated and nonirradiated red pepper powder were similar. Kakdugi prepared with irradiated red pepper powder required one week longer time for optimal ripening compared to the kakdugi control. Irradiated red pepper powder did not affect the hardness and fracturability of kakdugi during fermentation. Kakdugi prepared with irradiated red pepper powder maintained a redder color than the kakdugi control. No significant differences were observed in taste, odor, texture, and overall acceptability (p<0.05) except for color. It can be concluded that irradiation of red pepper powder, up to 7 kGy, did not affect the quality of kakdugi with regard to physicochemical and sensory characteristics during fermentation. Moreover, irradiated red pepper powder was better for maintaining the red color and delaying optimum ripening time of kakdugi fermentation.
