Data of the study were analysed using the sixth Korean National Health and Nutrition Examination Survey (KNHANES V-2, 2014). The subjects were elderly aged 65 years or more and the number of the sample was 1,263. Using hierarchial regression analysis, walking as a moderator of the depression and quality of life relationship was examined. Quality of life for elderly showed significant differences according to sex(t=8.26, p<.001), age(t=5.19, p<.001), number of chronic disease(F=37.88, p<.001), depression(t=9.62, p<.001) and walking per week (t=47.36, p<.001). Walking moderated the relationship between depression and quality of life in elderly.

  • This study was carried out to evaluate the effects of whey ferment containing L. acidophilus KCCM 32820 and P. freudenreichii KCCM 31227 on the quality characteristics of white pan bread. Instrumental analysis such as alveograph, gelatinization temperature, texture analysis, retrogradation rate was determined. In an alveograph test, $P_{max}$ value in the treatment was higher than that in the control, but extensibility of dough in the control showed to be higher than in the treatment, so test dough showed more strength than the control. In terms of DSC analysis for gelatinization, temperature there were no significant differences of $T_p$ and ${\Delta}H$ between the control and the treatment. In hardness analysis by rheometer, dough containing whey ferment revealed lower values than the control. From the analysis of the organic acid contents, propionic acid was not detected in the control, however 1.13 mg/g of propionic acid was detected in the treatment. In the retrogradation analysis by DSC, the test delayed slightly compared to the control.
