Whey based medium was optimized for the production of viable Lactobacillus crispatus KLB 46 isolated from the vagina of Korean women. Among the various nitrogen sources such as yeast extract, beef extract, and proteose peptone no. 3 supplemented to whey, beef extract showed the highest viable cell production. The addition of Tween 80 to the whey based medium increased viable cell concentration. As beef extract supplementation is not economically attractive, corn steep liquor was added as a supplementary nitrogen sources. When corn steep liquor was supplied with beef extract with the ratio 5:1, the viable cell count was 3.11 × 10? CFU/mL. Also, the addition of mineral salts containing sodium acetate (5 g/L), potassium phosphate dibasic (2 g/L), magnesium sulfate (0.1 g/L) and manganese sulfate (0.05 g/L) to the whey medium increased viable cell count further (5.00 × 10? CFU/mL).

The purpose of this study was to identify the relationship between perceived social support and the quality of life in hemodialysis patients. Data was collected from 81 hemodialysis patients in two general hospitals and one dialysis clinic for 9 days from Dec. 18 to Dec. 26. The perceived social support was assessed by the family support scale and the professional medical support scale, which were constructed by the researcher through literature review. The quality of life scale developed by Whal-Ranwere used. The data was analyzed by the S.P.S.S. statistcal software program. Percentile, means and standard deviation, t-test, ANOVA and pearson correlation were utilized for analysis. The result of this study were as follows. 1. The scores of the perceived social support of the subjects ranged from 24 to 120 with a mean score of 90.98, which the item mean score was 3.79. 1) The scores of the perceived family support of the subjects ranged from 12 to 60 with a mean score of 46.93, which the item mean score was 3.91. 2) The scores of the perceived medical support of the subjects ranged from 12 to 60 with a mean score of 44.05, which the item mean score was 3.67. 2. The scores of quality of life of the subjects ranged from 41 to 205 with a mean score of 128.46, which the item mean score was 3.133. For each factor in the quality of life scale, the mean score was as follows; for attitude toward life, 3.511, for physical symptom 3.430, for emotional status, 3.138, for healthy perception 3.091, for familial relationship and financial status, 3.086, for social activity, 2.722. 3. There was a significant difference in perceived social support according to sex(t=-.101, p=.003) and monthly income(F=5.420, p=.000). 4. There was a significant difference in quality of life according to sex(t=0.523, p=.009). 5. The result of the analysis of the relationship between perceived social support and quality of life showed a positive correlation(r=.486 p=.000). Therefore, the higher the perceived social support of the patients, the higher the quality of life. 1) The result of the analysis of the relationship between perceived family support and quality of life showed a significant correlation(r=.474 p=.000). Therefore, the higher the perceived family support of the patients, the higher the quality of life. 2) The result of the analysis of the relationship between perceived medical support and quality of life showed a significant correlation(r=.343 p=.002). Therefore, the higher the perceived medical support of the patients, the higher the quality of life. In conclusion, this study revealed that the social support is a positive correlation with the quality of life in hemodialysis patients.
