  • The application of the cellulase gene (celA) as a selection marker of food-grade integration system was investigated in Lactobacillus (Lb.) casei, Lactococcus lactis, and Leuconostoc (Leu.) mesenteroides. The 6.0-kb vector pOC13 containing celA from Clostridium thermocellum with an integrase gene and a phage attachment site originating from bacteriophage A2 was used for site-specific recombination into chromosomal DNA of lactic acid bacteria (LAB). pOC13 was also equipped with a broad host range plus replication origin from the lactococcal plasmid pWV01, and a controllable promoter of nisA ($P_{nisA}$) for the production of foreign proteins. pOC13 was integrated successfully into Lb. casei EM116, and pOC13 integrants were easily detectable by the formation of halo zone on plates containing cellulose. Recombinant Lb. casei EM 116::pOC13 maintained these traits in the absence of selection pressure during 100 generations. pOC13 was integrated into the chromosome of L. lactis and Leu. mesenteroides, and celA acted as an efficient selection marker. These results show that celA can be used as a food-grade selection marker, and that the new integrative vector could be used for the production of foreign proteins in LAB.

  • The purpose of this study was to analyze the structural relationships among selection attributes, satisfaction, and loyalty of green tea consumers, including their moderating effect of involvement. Questionnaires were administered to residents of Seoul and Gyeonggi-do province, who were 20 years old and older and who had purchased green tea. A total of 700 questionnaires were distributed, and 658 were finally used in the analysis. SPSS 15.0 and LISREL 8.80 were used for the analysis. Selection attributes had a significant effect on satisfaction, and statistical significance was observed with regard to factors such as marketing, production, sensory evaluation, and brand. No significant direct effect was observed between selection attributes and loyalty. Additionally, satisfaction had a significant effect on loyalty. The marketing factor had a negative effect on satisfaction in both the low- and high-involvement groups. The brand factor had a positive effect on satisfaction in the low involvement group, suggesting that developing and promoting a popular brand is essential. Sensory and utility factors had a positive effect on satisfaction in the high involvement group.

  • The purpose of this study aims to confirm the importance of customer selection attributes of beef restaurants. This study found a selection attributes for a beef specialty restaurant, and proved the hypothesis through empirical analysis. Along with the increase in income levels over the past decade, the restaurant industry has grown. In contemporary society, where quality of life is becoming more important, the restaurant industry has expanded the importance of service quality. In particular, for meat consumption, per capita beef consumption is expected to increase every year; the effect of the Korea-U.S. Free Trade Agreement is also expected to further increase the consumption of high-quality and high-priced U.S. beef. However, like the study of general restaurant-selection factors in restaurant management research, studies of beef restaurants and commercial studies considering consumers' selection attributes are scarce. This study verified the characteristics of consumer choice for restaurants specializing in beef, and how quality, price, restaurant atmosphere, and employee service impacted customer satisfaction. We suggest that beef restaurants should focus more on atmosphere and service in addition to food price and quality, which are the choice factors for restaurants in general. This study empirically verified the importance of selection attributes, providing theoretical and practical implications.

Secondly, the customers showed higher emotional motivation than utilitarian motivation. Thirdly, emotional motivation had a significant effect on perception of 'service', 'coffee quality', and 'atmosphere'. On the other hand, utilitarian motivation had a significant effect on 'service', 'diversity of menu', 'convenience', and 'price'.

Among all types of Japanese restaurants customers selected sushi bars the most (48.2%), and they considered taste (73.9%), price (34.8%), and service (22.2%) to be very important. When eating at Japanese restaurants, satisfaction differences among sanitation (p<0.05), price (p<0.05), and unique design (p<0.1) each had a significant difference with F values of 3.313, 3.208, and 2,702, respectively. factor analysis of the effect of selection attributes on Japanese restaurant performance revealed three factors; image, service, and food. Their combined satisfaction was 61.41%, and each of these three factors showed a Cronbach's ${\alpha}$ value of 0.744, 0.739, and 0.623 in the reliability analysis, respectively, thus demonstrating the overall level of reliability.
