A study is undertaken to examine the effects of the additional frozen blueberry powder and anthocyanin powder extracted from black beans to quality attributes of pound cakes. Frozen blueberry powder and anthocyanin powder extracted from black beans are being added to the flour at a ratio of 0.5, 1.5, 2.5, and 3.5% respectively. The antioxidant activity is highly correlated with the total phenolic and total flavonoids contents of frozen blueberry powder and anthocyanin powder extracted from black beans of pound cakes, respectively (r=0.8423, p<0.001 r=0.9449, p<0.001). The quality characteristics of the specific volumes decreased significantly with increasing substitution levels of frozen blueberry powder and anthocyanin powder extracted from black beans (p<0.01). The lightness significantly decreased with increasing frozen blueberry powder and anthocyanin powder extracted from black beans of pound cakes' crusts and crumbs (p<0.01). The hardness, chewiness and gumminess tend to reduce, while the cohesiveness increase in both powders. The consumer acceptability score for 0.5~3.5% of frozen blueberry powder and anthocyanin powder extracted from black beans pound cakes ranked significantly (p<0.01) higher than those of the other groups according to taste, flavor and overall preferences. These results show that frozen blueberry powder and anthocyanin powder extracted from the black beans are a good ingredient for increasing consumer acceptability and overall healthy.

The purpose of this study was to investigate the effects of black carrot (Daucus carota L.) on the quality characteristics and antioxidant activity of pork patties. Patties were provided with different amounts (0, 2, 4, 6 and 8%) of black carrot. Notably, the cooking loss rate of the group added with 8% black carrot was lowest (p<0.001). As the content of black carrot increased, the L value decreased and the a, b value increased. The texture analysis results showed that the hardness and chewiness to decrease as the amount of black carrot increased (p<0.05). Evaluation of consumer acceptability revealed that the 4% black carrot groups had a higher score in respect to overall preference and taste to the other groups (p<0.05). For antioxidant activities, both total phenolic compounds content and DPPH were increased (p<0.001) as the amount of added black carrot was increased. As a result, it can be concluded that adding the black carrot to patties in processing can improve antioxidant activities and quality of the patties. Considering various aspects of quality, the suitable amount is 4% of total weight.

This study assessed the quality characteristics of cookies made with different amounts (0, 5, 10, 15%) of black carrot powder. The density and pH value of cookie dough were constant for all groups. Compared to the control group, the moisture content was higher in groups containing the black carrot powder. Increasing the amount of black carrot powder resulted in decreased L-value but increased a-value. Furthermore, the hardness of cookies increased with increasing amounts of black carrot powder. The consumer acceptance test revealed that up to 15% black carrot powder addition was desirable. Total phenol content of the control group was 24.0 mg GAE/100 g, while black carrot powder groups ranged from 45.5 to 103.5 mg GAE/100 g. The DPPH radical scavenging activity was also augmented with increasing volumes of black carrot powder. Taken together, we recommend that cookies with 15% black carrot powder are desirable in terms of overall acceptability and antioxidant activity.

The purpose of this study is to find the meaning of women's fashion in the city culture of Paris in the nineteenth century by examining paintings by the Impressionists. The research method was based on literature survey and visual examination paintings, 224 paintings(by ${\acute{E}}douard$ Manet, James Tissot, Edgar DeGas, Gustave Cailleboat, Jean $B{\acute{e}}raud$, Pierre-Auguste Renoir) were analyzed in this study. The results are as follows: In the nineteenth century, Paris was a new city with new department stores. Department stores were centers of consumer culture, where the power of capital appeared rather than class. The spatial backgrounds of Impressionist paintings were places where they could see the consumption and leisure culture of urban people, such as outdoor parks, cafes, theaters, ballrooms, bars, streets, and the boats. As for the characteristics of women's fashion in paintings, it was found that various changes of artificial silhouettes were developed. Various frills, ruffles, gatherings, and pleats were thought to have been made by machines. In the urban space, many of the women's costumes stood out because of the black color. Not only the black color came to represent widows and mourning but the black outfits worn by women enhanced their sensual appearances. Women's fashion expressed in Impressionist paintings eventually contained a modern meaning that changed from 'class symbol' to 'expression of taste'. And the symbol of consumer and leisure culture showed, and a Demimonde's fashion became a trendsetter, and painters were used as an important element expressing modernity.
