Retail stores with a primary competitive advantage in satisfying customers with high quality differentiated services depend heavily on a sales force to produce and deliver services in a consistent manner. Salespersons in a high service retail context are required to act to express certain types of emotion in compliance with the emotional rules of the organization that is conceptualized as "emotional labor" in the literature. This study adopts the dyadic model of emotional labor originally proposed by Hochschild. A survey method is implemented to collect data to test the hypotheses among the variables such as positive and negative affectivity, performance stressor, emotional labor, burnout, and job satisfaction. One hundred and twelve responses were analyzed by factor analysis and path analysis with SPSS12.0 and Amos 6.0. The factor analysis confirms that emotional labor is composed of deep acting and surface acting. Eleven hypotheses were tested by path analysis and seven were accepted. The major findings are that deep acting was affected by positive affectivity, negative affectivity, and a performance stressor. The surface acting was affected only by negative affectivity. Surface acting had an indirect negative effect on job satisfaction via emotional burnout while deep directly acting influenced job satisfaction. Furthermore, the interaction effect between positive affectivity and a performance stressor on surface acting was significant. The implications for retail firms are discussed based on the findings with suggestions for future studies.

Flaxseed (Linum usitatissimum L.) is an important food, oil, and fiber crop of the family Linaceae. Although flaxseed has been consumed as a food ingredient for several centuries, its nutritional benefits have not yet been completely established. Flaxseed is a good source of lignans, nonstarch polysaccharides, and high-quality proteins. Hence, in this study, we aimed to prepare a bioactive kefir containing flaxseed and to examine the physicochemical characteristics of kefir containing different concentrations of flaxseed. We investigated the pH, and sensory evaluation of bioactive Kefir containing different concentrations of flaxseed. We investigated the pH, total anthocyanins (TAs), and sensory evaluation of bioactive Kefir containing different concentrations of flaxseed. The pH of this bioactive kefir decreased, whereas the TA content increased with increasing incubation time; however, these parameters were not affected by the amount of added flaxseed. As the addition rate of flaxseed increased, the scores for overall acceptability, texture, color, flavor, and taste in sensory evaluations were generally the same as or lower than the control. There were no significant differences in overall acceptability, texture, color, flavor, and taste between the control and treated groups. Therefore, further studies are needed to develop methods for production of health-improving kefir as a dietary supplement based on the functional properties of flaxseed.

There are more than 25 species of Mentha plants, which are aromatic perennial herbs. Currently, these species are being widely used with great interest because of various clinical findings regarding their health benefits. This is due to the abundance of volatile compounds that could expedite environmental interactions such as protection against herbivores, parasites, pathogens, and so on. Therefore, in this study, the antimicrobial effect of Mentha piperita (peppermint) oil on Bacillus cereus, Staphylococcus aureus, Cronobacter sakazakii, and Salmonella Enteritidis were investigated using the spot-on-lawn method. The results show that Mentha piperita (peppermint) oil exhibited antimicrobial activities against Bacillus cereus, Staphylococcus aureus, and Cronobacter sakazakii; however, it did not inhibit the growth of Salmonella Enteritidis. This shows that the antimicrobial effect of Mentha piperita (peppermint) oil is effective against both Gram-positive and Gram-negative bacteria. Hence, in the present study, Mentha piperita (peppermint) oil was shown to have strong antimicrobial activities; it could be used as a potential food additive for improving the quality of various milk-based products due to its various bioactive properties. Future studies should be conducted for manufacturing functional dairy products with the addition of peppermint oil to prevent and/or alleviate specific diseases.

In order to acquire a motif for the design, I analyzed several works of Gustav Klimt. As the result, those feature can be classified into the use of decorative lines, mosaic forms, and harmony of golden yellow and black, and it can be applied to buttons and clothes design. The sort of clay used in manufacturing the ceramic buttons was white clay to have high density and to diffuse light well, and press shaping techniques using plaster mold were employed. The baking was performed in an electronic kiln at $800^{\circ}C$ for the first time and at $1250^{\circ}C$ for the second time. Based on wearable designs in 2002/2003 F/W Trend of Interfashion Planning, I made three pieces of dress which could express the button's capability of decoration with effect. This is expressing a simplified form which shows up in details of and yellow and red pink were used to harmonize with golden yellow clothes. As an application of shapes of foliage in I transformed its size and form to be consistent with a jacket and a tube top. To accord with golden beige costume, I made a curve, showing up in Klimt's paintings, with golden color on a circle shape which was also a main motif in his paintings.

The purpose of this study is to analyze types of roles and fashion of the Chinese first ladies and provide basic data for fashion image-making of first ladies. As for the research methods, the concepts, role types, and fashion of the first ladies were considered by referring to the precedent studies and relevant literature. Then, the fashion images according to role types were analyzed by collecting the photos of Chinese first ladies from the period of the Republic of China until today. The results were as follows: First, when the roles of Chinese first ladies were categorized based on ceremonial, political, and policy roles, Zhuo Lin and Wang Yeping played a ceremonial role; Wang Guangmei, Liu Yongqing, and Peng Liyuan played a political role; and Soong Qingling, Soong Mayling, and Jiang Qing played a policy role while they were first ladies. While the first ladies of the Republic of China often wore classic Chinese styles like traditional qipao as well as western clothes which contained a western influence, the first ladies of the People's Republic of China wore more colorful clothes and more accessories in the later period, and also often wore clothes that combined traditional and western elements. Second, first ladies who played a ceremonial role showed mannish and classic images; those who played a political role showed elegant, classic, and diverse images according to T.P.O; and those who played a policy role showed feminine, modern, and mannish images. Fashion images of the first ladies varied according to the level of political involvement, the sociocultural background of China at that time, and their personality and preference.

The purpose of this study is to analyze women apparel's colors in the Seoul, Beijing, and Tokyo collections and examine the color characteristics of three collections through comparison with trend colors suggested by Carlin, a color forecasting group. A literature review and an empirical study were used for methodology. The literature review examined the status and characteristics of the three collections, a fashion color forecast, and F/W 2014-15 trend colors by Carlin based on previous researches and literature data on fashion color. The empirical study extracted and analyzed 2014-15 F/W women's ready-to-wear collections in Seoul, Tokyo, and Beijing and compared the result with trend colors by Carlin. First, the colors of women's apparel were analyzed in the Seoul, Beijing, and Tokyo collections. All three collections commonly used achromatic colors and the percentage of Bk, Gy, Wh, R, and B colors was high. All three collections used achromatic colors frequently for the main color and sub colors. For accent colors, while the application of achromatic colors was high in the Seoul collection, the application of chromatic colors was high in the Tokyo and Beijing collections. Second, women's apparel colors in the Seoul, Beijing, and Tokyo collections were compared with trend colors suggested by Carlin. All three collections highly reflected Bk, Wh, and R (Carlin's forecasting color of 'Splendor') and B (forecasting color of 'Boreal'). However, the reflection of metallic colors suggested as a keyword of 'Brave New World' and Pk color of 'Sensitive' and 'Boreal' were a bit low.

Salmonellosis caused by chicken consumption has been a critical issue in food safety worldwide, including in Korea. The probability of illness from consumption of chicken was simulated in study, based on the recipe of Dakgalbi, a commonly eaten chicken dish in Korea. Additionally, the processing stage at slaughterhouses to decrease Salmonella concentration in broilers was modeled to explore its effect on the likelihood of illness. A Monte Carlo simulation model was created using @RISK. Prevalence of Salmonella in chickens at the retail stage was found to be predominantly important in determining the probability of illness. Other than the prevalence, cooking temperature was found to have the largest impact on the probability of illness. The results also demonstrated that, although chlorination is a powerful tool for decreasing the Salmonella concentration in chicken, this effect did not last long and was negated by the following stages. This study analyzes the effects of variables of the retail-to-table pathway on the likelihood of salmonellosis in broiler consumption, and also evaluates the processing step used to decrease the contamination level of Salmonella in broilers at slaughterhouses. According to the results, we suggest that methods to decrease the contamination level of Salmonella such as chlorination had little effect on decreasing the probability of illness. Overall, these results suggest that preventing contamination of broiler with Salmonella must be a top priority and that methods to reduce the concentration of Salmonella in broilers at slaughterhouses hardly contribute to safe consumption of Salmonella-contaminated chicken.

Prevalence of childhood obesity is increasing significantly worldwide due to energy imbalance perhaps stemming from undesirable dietary behavior and physical activity level. The objective of the study was to examine the effects of physical activity level on nutritional status in elementary school students. The subjects were comprised of 287 elementary school students between 4th and 6th grades in Seoul, Korea. The level of physical activity was scored with a modified Godin leisure-time exercise questionnaire and was categorized as active, moderately active, and sedentary. Dietary intakes were obtained using a 24-hour food recall method. An analysis of variance (ANOVA) was conducted to test for global significant differences of nutrient intakes by physical activity level. Boys were more active than girls. Daily intakes of energy in moderately active boys were significantly higher than in the sedentary group, but intakes of calcium and iron in moderately active boys were lower than active boys. For girls, physical activity level did not affect nutrient density at all. Intakes of calcium, vitamin C, and folate for both boys and girls were below 50% of recommended intake. Physical activity did not affect nutrient density and our participants were exposed to nutritional imbalance. Therefore, the results suggest that nutrition education regarding balanced diet and optimum physical activity is required for children's health and growth.
