  • In order to compare the germination and growth rate of the sprouts soaked in highly concentrated oxygen water, it with specific amounts of oxygen dissolved was produced in a high pressure reactor by pressuring oxygen. The sprouts were observed after being soaked in $20^{\circ}C$ oxygen water with 20, 30, 40, 50 ppm of oxygen dissolved each. Results of ten days later indicate that the final germination rate of the sprout soaked in 50 ppm oxygen water was $24.6{\sim}28.6%$ higher than that of the sprout soaked in distilled water. The final growth length also measured 6-7 mm higher than the sprout soaked in distilled water, demonstrating that enough supply of oxygen to the sprout induces stability and efficiency in its growth.

  • The purpose of this study was to evaluate hot spring water (HSW) from Deokgu as a cosmetic ingredient in the preparation of a body lotion. The HSW was tested for its suitability as an aqueous-phase main component. Microbiological and chemical stability tests of the HSW were carried out. Microorganisms including E. coli were not detected or detected below the detection limits, and no harmful heavy metals were found. The cytotoxicity of the HSW was also considered, and its pH determined over a period of three months. Further, sensory characteristics were assessed for consumer acceptance by performing sensory tests on body lotions formulated using either Deokgu HSW or distilled water. Skin moisturization, irritation and tension reinforcement were found to be enhanced when using the HSW lotion rather than that formulated with distilled water. Taken together, the results of this study show that the use of HSW in cosmetic formulations contributes to the efficacy of these products.

  • This study was conducted to investigate the hepatic detoxification effect of microcluster-water (McW). Animal experiments were divided into 4 groups: distilled water intake group (DC), distilled water intake-bromobenzene treated group (DB), McW intake group (MC), and McW intake-bromobenzene treated group (MB). There were no significant differences in alanine aminotransferase and aspartate aminotransferase activities between DC and MC groups, but the activities in MB group were significantly (p<0.05) lower than those in DB group. No apparent changes of aniline hydrolase activity were shown in all experimental groups, while glutathione S-transferase activity in MC and MB groups was higher than that in DC and DB, respectively. The content of hepatic lipid peroxide in DC group was similar to that of MC group. In addition, the contents in DB and MB groups were significantly (p<0.05) increased than that of DC group. The increasing rate in MB group was lower than that of DB group. Also, the electron donating activity of McW was significantly (p<0.05) higher than that of distilled water. From these results, it could be suggested that McW has the possibility of having detoxification effect of bromobenzene induced hepatic injury by increasing glutathione S-transferase, which is known as a kind of hepatiic detoxification enzyme.

  • The purpose of this study was to confirm the quality characteristics of distilled soju with different rice pretreatment processes. The non-steamed fermentation method is a technology that uses starch to produce saccharification and alcohol without going through the steaming of raw materials. It has advantages such as reduction of manpower and cost, prevention of nutrient loss, and minimization of waste water. In this study, rice used were non-steamed and pulverized 'Baromi2', nonsteamed and steamed 'Samgwang', and puffed rice. As the fermenting agent, koji, modified nuruk, N9 yeast, and purified enzyme were used, and lactic acid was added to prevent contamination during fermentation. The amount of water was 300% in total, and after the first watering, 5 days after fermentation, the second watering was carried out. As a result of the study, it was confirmed that the non-steamed fermentation method using 'Baromi' was superior to the existing fermentation method in terms of temperature during fermentation, final alcohol content, soluble solids, and pH. By expanding the stability of the production technology of non-steamed fermentation technology, product quality improvement can be expected.

  • Water vapor permeability of films is commonly calculated from the water vapor transmission rate of the film measured using a permeability cup method which is essentially a gravimetric method. This method was originally developed for petroleum based plastic films with low water vapor permeability. In the case of hydrophilic bio-polymer films, the resistance caused by a stagnant air layer, which is developed between the underside of the film mounted on the cup and the surface of the desiccant saturated salt solution or distilled water, can be significant and, if neglected, ran lead to underestimation of water vapor transmission rates. Therefore, it is necessary to correct water vapor transmission rate data to accurately estimate the water vapor permeability of bio-polymer films.

  • This study was conducted to define a characteristics of Electrical Resistivity of weathered soil against volumetric water content and frequency. It is essential to analyze and understand a characteristics of the Electrical Resistivity for evaluation of soil as subsurface contaminant detection. Before the test, an effect of pore water and ion were checked using four liquids(distilled water, tap water, potassium chloride 1.8mM, and 3.7mM). As a result, the correlation between the volumetric water content and the Electrical Resistivity was estimated. The Electrical Resistivity decreases with increasing frequency and water content. Also, Electrical Resistivity could be described by an exponential function of volumetric water content with the constants.

  • The effects of dietary Coix(lacryma-jobi) water extract on the antioxidant enzyme activity in the liver and kidney of Sprague-Dawley rats were studied. Forty-five rats were fed for 3 weeks with either control diet or experimental diets that contain either Coix water extract or Coix water residue. Twenty percent of the carbohydrate was replaced with Coix water residue by dry weight in the water residue diet, while distilled water was replaced by Coix water extract to make a pellet-form diet in the Coix water extract diet. The levels of glutathione, glutathione-peroxidase, and glutathione-S-transferase activities in liver and kidney were measured . It has been found that glutathione, glutathione peroxidase, and glutathione-S-transferase enzyme activities from activities from liver and kidneyof the rats were enhanced in the group fed with Coix water extract.

  • The objective of this study was to measure the leaching of filler (Si, Ba) from nanofiller-contained composites (Palfique Estelite $sigma^{{R}}$ (Tokuyama Dental Corp., Tokyo, Japan), $Z-350^{{R}}$ (3M ESPE, USA), Ceram X duo $E3^{{R}}$, $D3^{{R}}$ (Dentsply, Konstanz, Germany)) under different conditions. The samples used for the study of leachable components were made by insertion of the material into a circular mold, 10 mm in diameter and 3.0 mm high. Each specimen was placed in a disposable polystyrene vial containing 5 mL of distilled water, artificial saliva or 0.1N NaOH and kept in an oven at $37^{\circ}C$. ; water and artificial saliva - 150 days, 0.1N NaOH - 15days. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) was used to determine the amount of Si and Ba in the test solutions. 1. Filler leaching was significantly great in 0.1N NaOH among all samples(p<.0.001). 2. When samples were stored in the distilled water, Estelite showed the lowest amount of Si leaching. When samples were stored in the artificial saliva, Z-350 showed the lowest amount of Si leaching. 3. There were significant differences in filler leaching between 3 storage medias and composite resins(p<.0.001). 4. Si and Ba leaching occurred in greater proportion when samples were stored in the artificial saliva than distilled water. 5. There were significant interactions in monthly filler leaching between leaching in artificial saliva and in distilled water, as well as the interaction between storage medium and filler(p<.0001). These results indicate that a continuous filler leaching of nanofiller-contained composite resins was in storing aqueous solutions under over time.
