The principal objective of this study was to determine the effects of service quality in a Korean restaurant in a Five Star Hotel in Metropolitan city causes on customers satisfaction, revisiting intentions and word of mouth communication. As a component of the study, 344 customers who had visited restaurants at 4 hotels were selected for our Q&A research, Our investigation was conducted largely frequency analysis, reliability analysis, factor analysis, and multiple regression analysis. First, as one of our study results, factors causing effects in service quality can be categorized into human service factors, physical service factors, and menu service factors. Second, the service quality of Korean restaurants has been found to exert effects on customer satisfaction, revisiting intentions, and word-of-mouth communication. Third, customer satisfaction has been determined to exert significant effects on revisiting intentions and word of mouth communication. Fourth, customer revisiting intentions has been found have been shown to exert significant effects on word-of-mouth communication. As one of the limits of this study, some difficulties did occur when attempting to implement Q&A research on customers who enjoyed restaurant services, as there was not sufficient space to interview them. As another limit, this study was conducted only with test subjects who had visited Korean restaurants in Five Star Hotels the results of our study cannot, then, be considered represent active of all Korean restaurants. Consistent with this future studies will need to be conducted not only with Korean restaurants, but also with Japanese, Chinese, and Western restaurants.

The aim of this study is to highlight the importance of the correct food choices and nutrition management through nutrition labeling and provide basic data for building a nutrition labeling system for Korean restaurants. In the study, a survey was conducted from February 5th to February 27th in 2010 involving adults over the age of 20 living in part of the Gyeonggi-do area. The data was used to analyze the general characteristics, the awareness of nutrition labeling and the nutrition labeling contents by using the SPSS 18.0 package program. Among the 268 people surveyed, the total number of women was greater (60.4%) than men (39.6%). The perception of the necessity of nutrition labeling was a relatively high score of 3.99 on a 1 to 5 scale and the motivation to utilize nutrition labeling scored 3.89. The study found that females perceived nutrition labeling to be more important than did the males. In addition, the perception varied according to the level of education and age. In conclusion, since customers have a high demand for nutrition labeling in Korean restaurants and are motivated to utilize labeling when eating-out is relatively strong, labeling would be a good educational tool for leading a healthy food life. Furthermore, since the study found that differences occur between nutrition labeling contents or nutrients according to general characteristics, food service companies might be able to gain benefits through differentiated nutrition labeling that is catered for their main customers.

The purpose of this study was to evaluate the service quality attributes of Korean restaurants by North American and Chinese residents in Korea based on the Kano model. This survey was performed from September to December 2010. The subjects consisted of 135 North Americans and 165 Chinese in Seoul. The service quality attributes of Korean restaurants were composed of twenty three items in the categories of 'food quality', 'employee's service quality', 'sanitation quality', 'facility quality', and 'convenience quality'. For North Americans, there were five 'attractive quality' items, eleven 'one-dimensional quality' items and six 'indifferent quality' items, and one item had the same frequency on both 'attractive quality' and 'one-dimensional quality'. For the Chinese, there were twelve 'attractive quality' items, and ten 'one-dimensional quality' items, and one item had the same frequency on 'attractive quality' and 'one-dimensional quality'. According to the customer satisfaction coefficient developed by Timko, 'taste of the 'food (0.80)' for North Americans and 'freshness of the ingredients (0.94)' for Chinese were highest scores in the 'Better coefficient'. On the other hand, within the 'Worse coefficient', 'sanitation of the food' had the lowest score for both North Americans (-0.89) and Chinese (-0.90).

Korean Food Globalization has been launched as a tool of civil ambassador and the high value-oriented industry. According to department of statistics in 2012, the trend of Korean food globalization from international visitors of Chinese and Japanese has grown. Hence, this study is purposed to identify the level of satisfaction of Chinese and Japanese consumers based on their food-related lifestyle. The survey was conducted by interviewing 403 Chinese and Japanese visitors who have experienced Korean food. The survey questionnaire was composed of 3 parts of demographic information, food-related lifestyle, and satisfaction of Korean restaurant. As factor analysis results, 3 factors were yielded for the food-related lifestyle factors-a eat-out preferred group, a health preferred group, and a taste preferred group, and 3 factors were generated for Korean restaurant satisfaction-hygiene and service, menu, and food quality. For cluster analysis, 3 clusters were identified as follows: high interested in food itself, health interested, and taste interested. Female appears to be significantly different in terms of 3 clusters than male. Nationality shows that Chinese consumers showed a high interest in food itself whereas Japanese consumers were high interested in health. With regard to Korean restaurant satisfaction, service appeared to be important in Chinese consumers while Japanese consumers showed a higher mean value on serving size, price, and nutrition. The findings concluded that by understanding the nature of food-related lifestyle of international visitors, marketing strategies can better meet visitors' expectations and increase their satisfaction with Korean restaurants.

The purpose of this study was to analyze the key factors considered important by customers in the selection of a Korean restaurant through the use of conjoint analysis techniques. A total of 400 questionnaires were distributed over a 2-week period in October 2011, of which 354 were completed (88.5%). Statistical analysis was then carried out using the Windows 18.0 Statistics package. The research was based on the analysis of two target areas - daily meals and special purpose meals. Responses were measured by using Zaichkowsky's Personal Involvement Inventory (PII) and a 7-point Likert Scale. Overall it was found that in all areas of the results regarding the involvement related analyses, daily meals scored lower than special purpose meals. This implied that the choice of daily meals is more applicable to customers with a low level of involvement, whereas high-involvement customers were more likely to focus on special purpose meals. The analysis of high-involvement customers revealed that the quality of food, price, service quality and physical environment, in order of priority, were the most important factors in selecting a restaurant. The use of the optimum attribute combination revealed the following results: delicious food (0.601); friendly staff (0.170); clean restaurant (0.191); price of 20,000 won (-0.513). Furthermore, low-involvement customers considered the following factors as important when selecting a Korean restaurant: quality of food, followed by price, physical environment and service quality in that order. In this instance, the optimum attribute combination showed the following outcomes: tasty food (0.645); friendly staff (0.418); clean restaurant (0.365); price of 5,000 won (-0.847). These results indicated the importance of developing a marketing plan which was based specifically on a customer's involvement level, focusing on their main selection criteria when choosing a Korean restaurant.

To find an efficient solution for the globalization of Korean food in Brazil, we conducted a survey about the satisfaction of Brazilian natives who had visited a Korean restaurant, and possible suggestions for improvement. We also conducted indepth interviews with 13 owners of Korean restaurants in Seo Paulo, Brazil, about their plans to improve Korean food to be more appealing to the Brazilian palate. Our research shows that Korean restaurants had a below average reputation for employee kindness, menu taste and variety, interior, mood, and accessibility. As a result of the survey, we found that Korean restaurants were considered in general to be below average. The survey also showed that the higher the level of a person's economic standing, the less satisfaction they had with Korean food restaurants. We also found that the most common pieces of advice that Brazilian women had regarding Korean restaurants were to offer more variety in the menu, maintain a cleaner restaurant, and to actively engage in public relations. The general concerns of everyone surveyed focused on cleanliness and public relations of the restaurant. However, food-related people focused more on the taste and quality of the food. Sao Paulo is currently the most well-developed economic center in South America, so the world's food service industry is pushed to the front of its ongoing development. For Korean food to make inroads into Brazil, Korean restaurants need to change the niche that they occupy. First-generation family businesses and second-generation specialized family businesses coexist in that city. So first of all, to localize the Korean food for Brazilian tastes, a menu system that will easily allow natives to access Korean food must be established. And second of all, it must support the total food culture by improving distribution, sanitation management, and marketing methods that can get the natives to like Korean food ingredients.

Whole soybean cereal was fermented with four fungal strains (Mucor and Rhizopus) in pilot meju fermentation system. The pH range of the fermented soybean cereal was $7.16{\sim}8.38$, the contents of reducing sugar and amino-nitrogen were $0.54{\sim}2.64%,\;93{\sim}312mg%$, respectively, and that of free fatty acid ranged $0.06{\sim}2.00%$. The components of the amino acid, organic acid, free sugars and fatty acid showed distinctive patterns among four groups of fermented soybean cereals. Amylase activity and carbohydrate degradation rate of R. oryzae, protease and protein degadation rate of R. stolonifer was higher than other strains. But lipase and lipid degradation rates of four strains were similar. The odor concentrates of the soybean cereals fermented with Mucor strains were similar to Aspergillus strains, but Rhizopus were possessed of the flavor components of Bacillus and Aspergillus. Soysauce, made from M. hiemalis and R. stolonifer fermented soybean cereal showed excellent sensory evaluation and it was proposed that the two strains will be useful in Korean soysauce process.
