  • The purpose of this study was to investigate the influences of children's perception of maternal acceptance-rejection and self-evaluation on learned helplessness. The Subjects were 371 fifth and sixth grade children. The helplessness scale, PAQ, PARQ were used. The data was analyzed by factor analysis, MANOVA, ANOVA and path analysis which was made through multiple regression analysis. The results were as follows: 1. The children's perceived maternal acceptance was significantly different depending on their parent's education level. In children's perceived parental rejection, there were gender differences. 2. In the children's self-evaluation, there were an interaction effect determined by the child's sex and the mother's education level, and a main effect of mother's education level. 3. Children's learned helplessness was significantly different depending on their mother's education level. 4. Children's perceived maternal acceptance(β=-0.36, p<.01) and rejection (β=0.17, p<.01) had a direct impact on their self-evaluation. Their self-evaluation(β=0.54, p<.01) and perceived maternal rejection(β=0.16, p<.01) had a direct impact on learned helplessness, but perceived maternal acceptance didn't have a direct impact on learned helplessness.

  • To provide the baseline for pricing, this paper proposes pricing-by-rating (PBR) as pricing model at micro-foundations level that can work as the baseline for all pricing models as well as an assessment criterion of business model in all circumstances. It sets up firstly WTP (willingness to pay/purchase) model from explicit needs and develops PBR based on the ordinal scale of the difference between the WTP and the WTS (willingness to supply/sell) by comparing individually the corresponding element/component of a firm's actual marketing mix 4P with that of the best SPEC (solution, price indicator by WTP, encouragement, channel) as an ideal 4P a customer expects and also by comparing the interaction between the 4P and the best SPEC as a whole collectively. And through illustrations it shows its applicability to evaluating business model in practice and finally asserts that PBR works as the baseline for pricing policy and as a criterion of business model evaluation in any circumstances.

  • The objective of this study was to determine the optimum mixing ratio of Opuntia humifusa powder and sugar in the preparation of muffin. The optimal sensory composite recipe was determined by following the central composites for muffin with different levels of Opuntia humifusa powder (A) and sugar (B). The analysis was performed using the response surface methodology, and the sensory evaluation was performed with the data. Ten experimental recipes, including two with reference points in the composition, were selected. The compositional and functional properties were measured, and the physical and sensory values were applied to the mathematical models. Perturbation plots showed the effects of each ingredient on the final product. Measurements showed significant values in lightness (p<0.05), sweetness (p<0.05), hardness (p<0.05), gumminess (p<0.05) and cohesiveness (p<0.01). The sensory measurements showed significant values in color (p<0.05), flavor (p<0.05), appearance (p<0.05), softness (p<0.05) and overall quality (p<0.05). Based on the numerical and graphical methods, the optimal formulation was determined to be 6.10 g of Opuntia humifusa powder and 82.61 g of sugar.

  • This study was designed to find out the optimum processing condition and the characteristics of yeots : In this study, Yeoteses were made from glutinous rice, Rice, Millet, Sorghum and Corn by microwave oven. The textural parameters of various Yeotses were determined by sensory evaluation and Rheometermeasurement. RESULTS : 1. The sweetness of all the raw materials before saccharification is 11%. In case of the sweetness of the raw materials after saccharification, Glutinous rice was the highest(28.8%) and Corn was the lowest(17.7%). Also, the sweetness of Glutionous rice Yeots was the highest(86%) and Corn Yeots was the lowest(82.7%).It showed similar tendancy to the sensory evaluation for sweetness. 2. The pH of the raw materials before saccharification was 4.4.The pH of sorgphum after-saccharification was the highest (4.7) and that of Corn was the lowest (4.3). 3. In the sensory evaluation of the various Yeotses, Glutinous rice Yeots showed the best quality and it did not showed any significant difference between glutinous Yeots and Rice Yeots.The overalll quality of Milet, Sorghum and Corn Yeotses were inferior to Glutnous and Rice Yeotses. Textural characteristics by Rheometermeasurement revealed differences among the various Yeotses. Hardness, Cohesiveness, Adhesiveness were the highest in Glutinous rice and Rice Yeotses. Adhesiveness showed similar tendancy to that of the sensory evaluation. 4. However, Becuase glutinous rice is more expensive than rice, it is desirable that we use Rice Yeots.

  • This study was conducted to obtain basic data about the effect of Lactobacillus delbruckii on the quality and preservability of the bread during bread making. The parameters measured to investigate the bread quality were water content, water activity, pH, hardness, shelf life and sensory evaluation. The results obtained were as follows : 1. During the storage period, moisture evaporated faster in normal bread than the sourdough bread(10, 30, 50%). 2. Normal bread showed 0.94 and sourdough bread resulted from 0.94 to 0.96 in water activity, 3. The concentration rate of sourdough and different dough method resulted in significantly difference value of pH in bread. As the sourdough concentration rate increased the pH changed from 5.5 to 4.5 in sponge dough method. However, the sourdough concentration rate increased, the pH dropped from 5.4 to 4.8 in the bread which made by straight dough method. 4. The normal bread showed tough texture than the sourdough bread as the storage period is extended. 5. As the ratio of sourdough increased, the pH became lower and the production of the off fiavor, the growth of mold delayed for one or two days when stored at 30$^{\circ}$C. 6. The bread with sourdough resulted in higher score than the normal bread by sensory evaluation. 7, The bread with 30% sourdough by straight dough method showed the highest score and the bread with 10% sour dough by sponge dough method resulted in the highest score by sensory evaluation.

  • This study intended to find out what the male and female university students in Kyung-book area think about Korean traditional foods, how much they use them, and how their life styles affect their estimates on traditional foods. They evaluated the aspects of traditional foods highly in the order of nutrition(6.07), taste(5.96), appearance(5.40), color(5.33), preservation after cooking(4.82), cost(4.63), and cooking method(4.43). Female students had higher estimates on traditional foods than male students. There was no significant difference in the evaluation between the students raised in rural and urban areas if they had the same educational level. Regardless of gender, Kimchi was most preferred followed by boiled rice, pot stew, grilled fish, and beef out of 25 traditional foods. In the correlation among the evaluation factors and uses of traditional foods, those with high evaluation on traditional foods(r=0.282, p<0.01) and the families with higher income(r=0.316, p<0.01) made more use of traditional foods. For the life style, leisure-valuing type was the greatest part(39.4%) in male students and altruistic type(31.9%) in female students. The altruistic type comprised of the greatest part(34.8%) among the students raised in urban areas and the leisure-valuing type(40.0%) among those raised in rural areas. The altruistic type students put high values on taste, nutrition, appearance, color, and preservation after cooking of the traditional foods. The egocentric type gave high values on cost and cooking method. However, there were no significant differences among the types in every item. The altruistic type put the highest and the leisure-valuing type put the lowest value on traditional foods, respectively, however, it was not significantly different. The individuality-centered type made the most use of traditional foods, whereas the leisure-valuing type made the least(p<0.05).
