The purpose of this study is to examine the effects of foodservice employees' workplace harassment on their coping styles and intention to leave. Based on total 374 foodservice employees obtained from the empirical research, this study reviewed reliability and fitness of research model and verified total 3 hypotheses. SEM was conducted to test the validity of the proposed model and the hypotheses. The structural model provided an adequate fit to the data, $x^2=1,344.862$ (p<.001), df=420, GFI=.839, IFI=.900, CFI=.900, RMSEA=.076. To examine how employees' workplace harassment affects coping with harassment; workplace harassment had a significant effect on self-doubt (${\beta}=.401$, p<.001), ignored bully doubt (${\beta}=.621$, p<.001), and indirect or passive doubt (${\beta}=.527$, p<.001); whereas problem solving (${\beta}=-.094$, p>.05) did not. Furthermore, employees' workplace harassment (${\beta}=.126$, p<.05) had no significant effect on intention to leave. Employees' coping with harassment had a significant effect on intention to leave; especifically, among employees' coping with harassment elements, problem solving(${\beta}=-.572$; p<.001), self-doubt (${\beta}=.369$, p<.001), indirect or passive (${\beta}=.239$, p<.001), and ignored bully (${\beta}=-.161$, p<.01) had a significant effect on intention to leave. Limitations and future research directions are also discussed.

This study showed that the brown stock, which is the base of demi-glace sauce, extracted by using a high pressure heating extractor is more advantageous than that extracted by the traditional extraction method for the mass production. We compared the former with the latter in terms of minerals and free amino acids. The results of this study are summarized as follows. When mineral contents were compared, the brown stock extracted by high.pressure heating extraction showed the tendency of increase in mineral contents in proportion to heating temperature and heating time, but, from extraction temperature of 140$^{\circ}C$, the contents of K, Mg, Na and P decreased with the increase of extraction time. In addition, mineral contents in the brown stock extracted by high-pressure heating extraction were generally lower than those in brown stock extracted by the traditional extraction method. This result was produced probably because materials were added repeatedly in the traditional method. Amino acids contents in brown stock according to the extraction methods were also examined. They increased with the increase in the number of extractions in the brown stock extracted by the traditional method, and those in the brown stock extracted using a high pressure heating extractor increased with the increase in heating temperature and extraction time. The results of this study are expected to be useful as a practical material for the mass production of brown stock products.

This study investigates quality improvement of pork-rib that is sold as a popular menu item in a family restaurant. It attempts to search the relation between pork-rib sauce and pork-rib through the sensory evaluation, physicochemistry properties and physical properties of pork-rib sauce. As a result, sensory preference of pork-rib and its sauce in TGIF restaurants was highest. The color of the pork-rib sauce was darker, and high salinity and low sweetness were preferred. As for viscosity, concentrations which are not thick were preferred. Also, sauce offered with pork-rib was closely related to pork-rib, so pork-rib menu in a family restaurant would be much preferred if the kinds of sauce become diversified.

Although the effect of menu quality is very important in customer satisfaction and restaurant management, there are so many problems; many restaurants have not gotten out of their existing frames and ideas of customer services and management. Thus, this study chose some family restaurants, O, T, V, B, M in Seoul and Gwangju and examined the relationships of customer satisfaction, trust and revisit intention identified by their menu quality, using statistical data of total 199 copies of questionnaire. First, menu quality turned out to influence customer satisfaction partially. Second, customer satisfaction turned out to influence revisit intention. Third, trust of a customer turned out to influence revisit intention. In this respect, the image from menu quality of family restaurants perceived by customers must have affected customer satisfaction, trust, and revisit intention positively. Thus, it is expected that the study can contribute to working out effective business strategies in family restaurants in future.

This study was conducted for the optimization of ingredients in salad dressing using Hwangdo peach (Prunus persica L. Batsch). The experiment was designed according to the D-optimal design of mixture design, which included 14 experimental points with 4 replicates for three independent variables (olive oil 40~65%, peach puree 27~50%, vinegar 8~20%). The linear regression models for pH, viscosity and color value and the quadratic regression models for emulsion stability, all sensory evaluation of the products were proven to be valid by the F-test for the overall significance of the regression model at a 5% level. Viscosity and pH of the products increased as olive oil content. Color value, viscosity and pH of the products increased as peach puree content. pH, viscosity, redness, and yellowness of the products decreased as vinegar content. Sensory evaluation result of the products showed that general preference for the products were increasingly affected by the increases in contents then decreased as they exceeded the optimum levels. In consequence, according to result from the first stage of the experiment, the optimum ingredients ratios of the raw materials were set in olive oil 52.43%, peach puree 35.07%, and vinegar 13.91% for ingredients of apricot dressing. These results provided the possibility that peach can be applied to the preparation of a dressing, and thereby present baseline data for the development of new dressings. This is also presumed to meet demands of customers who are always in pursuit of new products.

Jungkwa is traditional food in Korea and difficult to prepare. This study proposes to use a rice cooker to simplify the process of preparing ginseng jungkwa. The following is the summary of the study. This study examined low calorie sweeteners (xylitol, oligosaccharide, stevioside, erythritol) instead of sugar for ginseng jungkwa to satisfy customers' health needs. After adding sugar, xylitol, oligosaccharide, stevioside, and erythritol to ginseng jungkwa, moisture and sugar content were measured. Based on the results, the ginseng jungkwa made with xylitol had a low moisture content, but it had the highest sugar content. The ginseng jungkwa with xylitol had average sweetness equal to that of sugar. In addition, L-values were highest with stevioside whereas the b-values and a-values were highest with sugar. Hardness and springiness were highest in the ginseng jungkwa added with sugar while adhesiveness was highest in the ginseng jungkwa added with oligosaccharide. In a sensory evaluation, the appearance, flavor, taste, texture, and overall preference were highest for the oligosaccharide added ginseng jungkwa. In the end, the best low calorie sweetener for rice cooker prepared ginseng jungkwa proved to be oligosaccharide.
