A study of the comparison of customers' satisfaction and loyalty at McDonald's two types of outlets is presented. The objective of this study is to test correlation among selection attributes, customer satisfaction and loyalty of customers patronizing two types of Mcdonald's restaurants - stand alone and co-branded, as Mcdonald's is known to be actively participating in co-branding with discount stores such as E-Mart. In order to measure customer loyalty, benchmark scores from customers showing extreme satisfaction are compared to the mean scores of total sample customers at each outlet. Meeting or exceeding benchmarking scores does not automatically bring in and create loyal customers but in doing so will certainly help build up strong customer relationship which will create additional loyalty. Marketers should be well aware that statistically significant difference do exist between these two groups of customers and should take into consideration these findings in opening up new outlets or renovating existing outlets.

This examination was conducted as follows; 189 copies were coated in total, and demonstratively analyzed by SPSS WIN 15.0 program. The methods used in data for this analysis are as follows; Sensitivity, Reliability, Frequency, Internal consistency, One way ANOVA(Scheffe's examination) Analysis, T-test, etc. The findings of this study are as follows; firstly, it was revealed that respondents who were regular customers of Italian restaurants regarded convenient transportation, property of space, property of pastoral, visibility, and accessibility as importance. This means that Italian restaurant marketers should consider some of factors of location for business with a good view, good parking lot, location at main street, smooth flow of traffic, luxury, atmosphere of freedom, clean area around restaurants, elegant interior of the building, comfortable, luxurious, and deluxe atmosphere, and so on. Secondly, it was revealed that respondents who were regular customers of buffet restaurant either considered the same factors as the Italian restaurants above or regarded those factors less important. This suggests that restaurants should be located on main streets, on trunk roads, and in large-scale residential districts of apartment complex. Thirdly, it was revealed that respondents who were regular customers of traditional restaurants did not consider the locational factors above. This shows that traditional restaurants should be located in nearby customers' houses or their working places, and that marketers should consider focusing on their restaurants' homelike atmosphere, cleanliness, food flavors, and so on.

The test results of Teriyaki sauce produced adding pomegranate concentrate are as follows: pH of Teriyaki sauce adding pomegranate concentrate showed significant difference among all samples (p<0.05). In case of sugar content, the higher the amount of pomegranate concentrate rose, the higher in sugar content it was. The test result of the amount of water showed significant difference among all samples (p<0.05). As the amount of added pomegranate concentrate was increased, the amount of water in the sauce was decreased. For viscosity, as the amount of added pomegranate concentrate was increased, viscosity of Teriyaki sauce was increased. The test result of chromaticity showed that as the amount of added pomegranate concentrate was increased, brightness (L), redness (a), and yellowness (b) were increased. According to the result of sensory evaluation, overall-acceptability was 7.5 highest at 6% compared to the control group.

Mustard Leaf Kimchi (MLK) is a traditional fermented Korean vegetable food. This study investigated the anticancer effect of partial vacuum treatment of MLK packed in glass bottles during fermentation. Prepared vacuum treated mustard leaf Kimchi (VM) and non-vacuum treated mustard leaf Kimchi (CM) were fermented at $5^{\circ}C$ for 8 weeks. The initial pH and total acidity were approximately 5.7 and, 0.36%, respectively. During fermentation, pH decreased and total acidity increased. Initial contents of reducing sugar and salt were 2.1% and were 2.7 mg/g, respectively. Reducing sugar gradually decreased during fermentation. Growth of cells from mouse cancer cell lines (L12l0 and P338D1) and human cancer cell lines (HepG2 and WiDr) were all decreased by MLK. VM and CM did not affect growth. More potent growth inhibition effects were exhibited by water versus hexane extracts of MLK, and by MLK fermented for 3 weeks versus 6 weeks. However, when applied to control NIH/3T3 cells at the same concentrations, MLK exhibited no cytotoxicity, and cell growth was unimpeded.

The overall effects of three different beers on white bread were examined in terms of mixograph, pH, fermentation rate, TPA, crumbScan, colorimeter, sensory evaluation, and the hardness of bread through different storage times (0, 1, 2, 3 days), and texture as measured by texture analyzer. According to mixograph, the control (CON), black beer stout (BOB) and Asahi beer (AOB) but not max beer (MOB) were found to be proper between 3 and 5 minutes of peak time. All samples for peak value were at the level of over 60%. AOB showed the highest specific volume, and was the lowest in hardness (i.e. highest in softness) by TPA and storage days. In sensory evaluation, the difference test showed that AOB had the best volume, springiness, moistness, and softness. Moreover, in an overall preference test AOB scored the highest points in texture, flavor, taste, and overall acceptance.
