This study sought to determine the physicochemical and sensory qualities of yogurt dressing prepared with different levels Aronia juice(0, 10, 20, 30, and 40%). As the amount of added Aronia juice increased, malic acid, acetic acid, and citric acid contents increased, although tartaric acid and lactic acid contents decreased. The viscosity of the control group(4,296.67 cP) was higher than those of the other groups(1,466.67~3,496.67 cP). The pH of the yogurt dressing containing 10% Aronia juice(3.83) was higher than those of the other groups(3.59~3.74). The sweetness of the yogurt dressing containing 10% Aronia juice($5.17^{\circ}Brix$) was higher than the other groups($2.47{\sim}3.47^{\circ}Brix$). Lightness decreased significantly, whereas a value and b value increased significantly with added levels of Aronia juice. DPPH radical scavenging activity of the control group was 7.42%, whereas those of the yogurt dressing samples with Aronia juice ranged from 26.30-69.86%. The sensory property results showed that the 20% Aronia juice added yogurt dressing group had the highest value in terms of color, thickness, taste, mouth feel, and overall acceptability. Overall, the results of this study indicates that the yogurt dressing containing 20% Aronia juice was the most preferred among the groups.

A total of 350 questionnaires were collected of which 28 were deemed unreliable, leaving 322 responses to be used in the analysis. SPSS 22.0 was employed to carry out frequency analysis, factor analysis, and reliability analysis, correlation analysis, and regression analysis. First, choose eat out properties multiple regression analysis on the impact on customer satisfaction, overall explanatory power of the regression equation $R^2=.521$ (adjusted $R^2=.515$) and F values were analyzed statistically significant the influence of the positive (+) with 86.325 p=0.000 and the regression equation. Content type pursuit of independent variables (B=0.540, p<0.001), seeking safety type (B=0.292, p<0.001) were significantly appeared showed the influence of the positive (+), Pursuit convenience-type (B=0.071, p<0.001) and the pursuit of dignity type (B=0.002, p<0.001) the sub-showed the influence of (-). Second, the multiple regression analysis on the impact on customer satisfaction to others is recommended explanatory power is $R^2=.539$ (adjusted $R^2=.538$) and F values are analyzed by a statistical regression equation p=0.000 and 374.765 in significance showed that the model fit the regression line. Customer satisfaction is the independent variable was the influence of the positive (+) to (B=0.540, p<0.001).

Collected basic data were analyzed through SPSS 18.0 program by frequency analysis, correlation analysis, factorial analysis, reliability analysis, regression analysis, and so on. I suggested like this for managing effective human resources. For increasing satisfaction of duty of barista, manager should give opportunity for attending important duty to barista, and because of this, barista can feel sense of responsibility and self-esteem.

Of the 500 copies of survey questionnaires distributed, 391 were used for the analysis. The method used for this analysis was the SPSS for WIN 12.0 program and the analysis such as technical statistics analysis, reliability analysis, research element analysis and regression analysis were applied. As a result, the service shortage factor which is one of the service process failures was confirmed to affect procedural justice and distributive justice. It has been confirmed that procedural justice and distributive justice are influenced by the hygiene deficiency which is one of the result failures. It was also found that the product factor affects distribution justice.

The purpose of this study was to examine the optimization and quality characteristics of balsamic vinegar jelly by the addition of various gelling agents: agar, gelatin, arrowroot starch, potato starch. For this purpose, mechanical tests(moisture content, color value, pH, sugar content, texture) and sensory tests(quantitative descriptive analysis & acceptance test) were conducted, showing the following results. The moisture content of balsamic jelly was the highest in the gelatin addition group, the color intensity of the L value in the potato starch addition group, redness a value in the gelatin addition group, and the b value(yellowness) in the agar addition group. The pH of balsamic jelly was the highest values in the gelatin addition group while its sugar content was the highest values in the arrowroot starch addition group. As a result of measuring balsamic jelly texture, there were significant differences in hardness, chewiness and gumminess by gelling agents. In the quantitative descriptive analysis of sensory test, the gelatin addition group showed the most high level in purple color intensity, glossiness, transparency, and chewiness. As for the acceptance in the sensory test, the gelatin addition group showed the most high level in appearance, taste, texture, and overall acceptance, which also had a significant difference. In case of balsamic flavor, Arr added arrowroot starch showed the highest values, which also had a significant difference.

This study was conducted to examine the characteristics of bread quality as per addition rate of citrus mandarin peel powder since interests and concerns about healthy functional food have been increased in contemporary society. The result of mixogram from Mixograph showed that dough added with 3% citrus mandarin peel powder was suitable for baking quality. Stickiness of dough was decreased with addition of citrus mandarin peel powder. Compared with the controlled group, fermentation rate was decreased as the level of citrus mandarin peel powder increased while pH levels of dough and bread were significantly decreased. The TPA analysis showed that the hardness and adhesiveness levels increased as the level of citrus mandarin peel powder increased whereas springiness, cohesiveness and chewiness became decreased. Crumb fineness and elongation became higher as seen from the result of crumbScan. Volume and specific volume was decreased. The result of preference test presented that crumb color, texture, flavor and taste were the highest in the M3, which showed highest point in overall preference. In conclusion, M3 was the best in preference, taste and texture, thus determined as the optimal rate in association with the addition of citrus mandarin peel powder.
