BACKGROUND: Salt accumulation in coastal reclaimed soil can decrease plant growth and productivity, which could lead to considerable variation of methane($CH_4$) emission in a rice paddy. The objective of this study was to evaluate the effect of salt concentration on $CH_4$ emission in a coastal reclaimed soil. METHODS AND RESULTS: The effect of salt concentration on $CH_4$ emission and rice growth characteristics was studied by pot test, which packed by reclaimed paddy soils collected from Galsa, Hadong, Gyeongnam province. Electrical conductivity(EC) of each treatment was controlled by 0.98, 2.25, 5.05 and 9.48 dS/m and $CH_4$ emission was characterized a week interval by closed chamber method during rice cultivation. The $CH_4$ emission rate was significantly decreased with increase of salt accumulation, but total $CH_4$ flux in EC 5.50 dS/m treatment was lower than those of EC 9.48 dS/m treatment. It seems because of higher content of water soluble $SO{_4}^{2-}$ in EC 5.50 dS/m treatment than those of EC 9.48 dS/m treatment. Rice growth and grain yield were significantly decreased with increase of salt accumulation. Soil properties, especially EC and pH were negatively correlated with $CH_4$ flux, while rice growth characteristics like plant height and tiller number show significantly positive correlation with $CH_4$ flux. CONCLUSION(S): Conclusively, salt accumulation significantly decreased $CH_4$ flux in a rice paddy, which could be useful information for evaluating $CH_4$ flux in reclaimed area in Korea.

Silver has potent antibacterial activity against a variety of bacteria while maintaining low toxicity in mammalian cells. This study was conducted to investigate the possible mechanism underlying the bactericidal effects of silver ions against bovine mastitis pathogens using electron microscopy. We used two different bacterial strains, Escherichia coli and Staphylococcus aureus, which are primarily responsible for the majority of bovine mastitis cases. Interaction between the bacteria and silver ions (50 ${\mu}g/mL$, 2 hours) were studied using energy-filtering transmission electron microscopy (EFTEM). EFTEM images showed that E. coli and S. aureus cells treated with the silver ions had distorted plasma membranes, silver ions attached to the outer membranes, scattered electron-light material, and leakage of cell contents from disrupted cell membranes.

The potential therapeutic effect of ozone gas on bovine mastitis was investigated. Eighteen quarters from 18 lactating cows with chronic mastitis were included. The 18 quarters were assigned to the control group (treatment with antibiotics for 3 days), experimental group I (0.1 ppm ozone treatment, for 7 days) and experimental group II (1ppm ozone treatment, for 3days). In experimental group I, milk somatic cell counts were lower on day 7 after ozone treatment, compared to the pretreated counts, but were higher than the control counts. In experimental group II, somatic cell counts were significantly decreased (p<0.05) on day 7 compared to the pretreatment counts, and they were lower than the control counts. There were no changes in leukocyte, neutrophil, or lymphocyte numbers, N/L ratios, N/L ratios, or serum total protein in the control and experimental groups. We concluded that ozone gas treatment(1ppm for 3days) might be effective for treatment of bovine mastitis.

Four different fermentation methods of Korean cucumber pickles were compared with conventional method, pickling in 10% NaCl solution at $25^{\circ}C$, in order to improve the storage stability. The methods studied were brining the cucumbers in hot($90^{\circ}C$) 10% NaCl solution(method A), addition of KCl and $CaCl_2$ into the hot salt solution(method B) addition of a sodium salts mixture of phosphates, nitrite and citrate into half fermented pickles prepared by method B(method C), substituted nitrite and citrate with KCl in method C(method D). It was found from results that the method C and D reduced the decreasing rate of pH very significantly by more than 3 fold and method B also showed the reducing effect. However, higher total acidity was measured for method C and D, which was opposite to pH results. Changes in hardness of cucumber showed little difference to control while color of brining solution exhibited some difference in their Hunter values. Organoleptic comparison showed a clear effect of salts mixtures by receiving the significant higher scores in fresh cucumber flavor and lower values in yeast moldy and sour flavor for method C and D when those were compared to control.

Many animal models of osteoarthritis (OA) have been developed, aimed at understanding the long-term progression of OA and difficulty of identifying patients in the initial stage of the disease. In canines, coxofemoral luxation and hip dysplasia are common orthopedic ailments related to OA in the hip joint. Transecting the ligament of the head of the femur (LHF) aids in diagnosis of coxofemoral joint OA. Presently, mobility of this joint was increased by transected LHF in 10 mature, 2-3-year-old (average $2.57{\pm}0.20$ years), healthy male beagles. The animals were normally gaited 1-week post-operatively. During the experimental period, examinations including X-ray, complete blood count and serum chemistry were unremarkable. Proteomic examination revealed protein alterations in synovial fluid, with significant increases in Vitamin D-binding protein precursor (ANOVA, p < 0.004) and Kinogen-1 (ANOVA, p < 0.039). Both proteins correlated with arthritis.

In order to estimate the effect of nutrients addition for phytoplankton growth and community compositons in spring and summer season, we investigated the abiotic and biotic factors of surface and bottom waters at 20 stations of inner and offshore areas in Gwangyang Bay, Korea. Nutrient additional experiments were also conducted to identify any additional nutrient effects on phytoplankton assemblage using the surface water for the assay. Bacillariophyceae occupied more than 90% of total phytoplankton assembleges. Of these, diatom Eucampia zodiacus and Skeletonema costatum-like species was mainly dominated in spring and summer, respectively. Here, we can offer the season why the two diatom population densities were maintained at high levels in both seasons. First, light transparency of spring season in the euphotic zone was greatly improved in the bay. This improvement is one of important factor as tigger of increase in E. zodiacus population. Second, low salinity and high nutrient sources supplied by Seomjin River discharge are a main cue for strong bottom-up effects on S. costatum-like species during the summer rainy season. Based on the algal bio-assays, although maximum growth rate of phytoplankton communities at inner bay (St.8) were similar to those of outer bay (St.20), half-saturation constant ($K_s$) for phosphate at outer bay was slightly lower than those of inner bay. This implied that adapted cells in low nutrient condition of outer bay may have enough grown even the low phosphate and they also have a competitive advantage against other algal species under low nutrient condition. In particular, efficiency of N (+) addition in summer season was higher compared to control and P added experiments. In the bay, silicon was not a major limiting factor for phytoplankton growth, whereas nitrogen (N) was considered as a limiting factor during spring and summer. Therefore, a sufficient silicate supply form water mixing Si recycled from diatom decomposition and river water is favorable form maintaining diatom ecosystems in Gwangyang Bay.

The evaluation of functional active ingredients and dyeing effect on cotton fabric using 16 types of natural products water extracts and 50% ethanol extracts, there were differences in color intensity, but 6 types of red, 5 types of yellow, 2 types of orange, and 3 types of green were observed. In general, the color of the 50% ethanol extract was high and clear. As a result of dyeing by immersing cotton gauze in water extracts and 50% ethanol extracts of these natural products for 2 days, the dyeing effect was generally good, and it was observed that there was little fading decrease in color even after drying at room temperature and opening and storing. The pH of the water extracts of 16 natural products ranged from neutral to slightly acidic, with no side effects on the skin. For DPPH free radical inhibition antioxidant effect, the effect of 50% ethanol extract for each sample was better than that of water extract. As for the polyphenol content, the content of the 50% ethanol extract tended to be higher than that of the water extract. Therefore, the purpose of this study was to investigate the correlation between the antioxidant activity of 16 natural extracts and the prevention of female vaginitis.

This study was conducted to investigate the effects of kinesio taping on the pain and functional improvement of patients with degenerative arthritis. 40 female patients were participated in this study. To evaluate the effects of taping therapy we calculated pain, range of motion, and get up and go(GUG) test. The results were as follow: Pain of experimental and control group were significantly decreased after than before treatment, but there was significant difference between experimental and control group. ROM of experimental and control group were significantly increased after than before treatment, but there was significant difference between experimental and control group. Time of GUG of experimental and control group were significantly decreased after than before treatment, but there was significant difference between experimental and control group. And Steps of GUG was significantly decreased only experimental group. So we think that kinesio taping have effectiveness on the pain and functional improvement in patients with degenerative arthritis.

In this thesis, we took some stalks, flowers, and leaves of the Serratuls coronate var. insularis which are able to propagate as mass n our wild to extract the dyeing solution, and cotton and silk were dyed using them in many different conditions. Silk was dyed darker than cotton. We found there was not a big difference between silk and cotton in the given condition considering 'Y' values vs. dyeing temperature. There was a rapid decreasing of 'Y' values after one to two hours and almost all of dyeing was completed at these times. We found there was a dyeing acceleration at the higher dyeing density and the lower 'Y' value. If the density was low, dyeing attachment was reduced by dyeing ability via the density of liquid in both plants. Silk was affected higher by mordant dyes in both plants. Fe and Cu had an effect by mordant dyes slightly an Serratuls coronate var. insularis.

In this thesis, we took some stalks, flowers, and leaves of the Hypericum ascyron L. which are able to propagate as mass in our wild to extract the dyeing solution, and cotton and silk were dyed using them in many different conditions. Silk was dyed darker than cotton with increasing the pH density. Silk was dyed darkest among Hypericum ascyron if pH was neutral. We found there was not a big difference between silk and cotton in the given condition considering 'Y' values vs. dyeing temperature. However cotton was dyed darker in hypericum ascyron. There was a rapid decreasing of 'Y' values after one to two hours and almost all of dyeing was completed at these times. We found there was a dyeing acceleration at the higher dyeing density and the lower 'Y' value. If the density was low, dyeing attachment was reduced by dyeing ability via the density of liquid in this plants. Silk was affected higher by mordant dyes in this plants. Fe and Cu had no effect on Hypericum ascyron.
