This study was conducted to compare the preference and satisfaction for Korean traditional foods (Jeonju Bibimbap, Daetongbap, Jeonbokjuk, Jorangiddockguk, Hobakbumbuk, Darkgalbee, Eonyang Bulgogi, Moyackgwa, Insam Jeonggwa, Maejackgwa) in foreigners and Koreans. In this study, 27 foreign and 31 Korean university students were surveyed. Statistical analysis and Mann-Whitney U test were performed using the SPSS statistical package (17.0). The major findings were as follows: 1) Foreigners had higher experience of eating Darkgalbee (84.6%), Jeonju Bibimbap (80.8%), Daetongbap (53.8%), and Jeonbokjuk (53.8%) among Korean traditional foods, whereas their eating experience of Insam Jeonggwa (3.8%), Maejackgwa (11.5%), Moyackgwa (15.4%) and Jorangiddockguk (23.1%) was lower. 2) Foreigners and Koreans both liked sweet taste, but disliked sour taste, bitter taste, garlic flavor, sesame flavor, and soy sauce flavor among the sensory characteristics of Korean traditional foods. 3) Foreigners scored their overall satisfaction of Korean traditional foods in the order of Jeonju Bibimbap (7.70±0.95), Eonyang Bulgogi (7.62±2.10), Daetongbap (7.59±1.60), Darkgalbee (7.20±1.56), and Jeonbokjuk (6.67±1.64), whereas Koreans rated higher scores for Eonyang Bulgogi (8.28±1.19), Darkgalbee (8.20±1.00), Jeonju Bibimbap (7.73±1.08), Jeonbokjuk (7.69±1.44), and Moyackgwa (7.43±1.52).
This study presents the Analytical Hierarchy Process (AHP) as a potential decision-making method for obtaining the relative weights of alternatives through pairwise comparison in the context of hierarchical structure. The aim of this study was to elicit prior strategies for brand communication for Korean restaurants overseas. We created a questionnaire and surveyed experts at government agencies, restaurant companies, and universities from October to November 2011. By applying the pairwise comparison matrix, relevance was perceived as a more important strategy evaluation criteria than effectiveness or urgency. The highest-ranked strategy was the 'Identification of the BI and positioning of Korean restaurants' followed by 'Development of Korean food content for overseas promotion', 'Development of locally customized Korean food recipes and new Korean menus', 'Development of marketing communication strategies for Korean restaurants by countries', and 'Development of Korean restaurant differentiation strategies'. The results of this study can be used for effective Korean food globalization by enhancing the competitiveness in the world market.
The purpose of this study was to analyze methods and contents of global Korean food marketing. In-depth interviews were conducted from July to October in 2010 using a qualitative research approach. Government agencies and restaurant companies emphasized well-being and healthy aspects as a Korean food identity. Regarding the marketing contents, government agencies commonly included standard loanword orthography and recipes. On the other hand, restaurant companies contained their own contents differentiated from other brands. Government agencies used CF, video, book and newspaper as communication channels but restaurant companies did not have systematic communication channels. Government agencies attempted to use holding, supporting and participating expositions as communication methods, whereas restaurant companies mainly used sales promotion and point-of-purchase as communication methods.
In recent years consumers have become used to products geared toward a more convenient lifestyle, thus, the demand for salted-cabbage, for use in preparing Kimchi is increasing. This study aims to investigate purchasing factors, the satisfaction and demands of salted-cabbage, and to ascertain a marketing strategy for expanding the use of salted cabbage in food-service departments of schools. Self-administered questionnaires were collected from 131 buying agents who manage food materials for schools, and statistical data analysis was completed using the SPSS V.14.0 program. 46.9% of the participating respondents were from elementary schools, 27.7% from middle schools, and 25.4% were from high schools.. Most of the subjects (67.9%) recognized the salted cabbage retailed for foodservice, but 62.3% of these had not purchased them, due to both their lack of trust in the sanitation and raw material handling of the food product, and the high price. Respondents considered different factors when deciding whether or not to purchase: the origin (local or imported) of the cabbage, hygiene, and taste, as well as characteristics such as the cabbage weight, package weight, and package materials. The score of post-behavior intentions as well as overall satisfaction was rather high. Also, they perceived the need of strategic promotion for enlarging the market portion of salted-cabbage. These results will done the guidelines for diversifying the salted-cabbage market and for creating an added value of agricultural products in rural areas.
The consumer acceptance of food is not only affected by the sensory characteristics of food but also by the non-food factors, including food experience, consumption frequency, and food attitudes. Therefore, food attitude scales such as the food neophobic scale, VARSEEK scale, Dutch restrained eating scale, health taste attitude scale, etc. have been developed and effectively used to predict consumer liking and behaviors. Since the globalization of Korean food is currently one of the hottest topics in the Korean food industry, the aim of this study was to identify the tastes and flavors that may represent Korean cuisine. Additionally, an attitudinal scale for Korean taste and flavors was developed, which can then be utilized to predict a consumer’s liking of Korean food. In the first stage of the experiment, the representative taste and flavors of Korean cuisine was surveyed by a Korean culinary expert group (n=23) and general consumers (n=62). As a result of these surveys, 4 types of flavors, hot pepper flavor, ‘goso’ flavor, garlic flavor, and fermented flavor were shown to be the most representative flavors of Korean cuisine. Based on these results, the second stage of the experiment was carried out to develop an attitudinal scale for Korean style flavors. Eleven to 17 questionnaires were developed for each of the 4 types of flavors. The survey consisted of a total of 53 questionnaires and 154 female consumers and 158 male consumers participated in the survey. The data was analyzed by factor analysis. For each type of flavor, the final attitudinal questionnaires were selected based on the following criteria: 1. high absolute factor loading value, 2. carrying clear meaning of the corresponding flavor attitude, and 3. delivering the meaning sufficiently when translated into other language. The final Korean style flavor attitude scale consisted of 7 hot pepper flavor, 6 ‘goso’ flavor, 6 garlic flavor, and 7 fermented flavor questionnaires. In the next step of this study, experiments will be carried out to validate the Korean style flavor attitude scale.
The purpose of this study was to survey the current status of bread menus at school, business and industry (B & I), and military foodservice operations and to analyze dietitians' perceptions of applying rice bread in foodservice menus. A questionnaire, which was developed by content analysis, situation analysis, and in-depth interview, was distributed to 183 schools, 31 B & I operations, and 26 air force dietitians. In the school and B & I foodservices, wheat bread was used much more than rice bread and serving frequencies of morning rolls and sliced bread were higher. The military foodservices, however, served much more rice bread as burger buns than the other groups. For the school and B&I operations, consumer preference for wheat bread was perceived as high. In contrast, soldiers preferred rice bread to wheat bread in the military foodservices. The recognized advantages of using rice bread were different among the three groups. The military dietitians perceived the main advantage of using rice bread as an increase of rice consumption, while the school and B & I dietitians viewed it as promoting a healthy image. In all groups, the primary difficulties for using rice bread were the higher cost of rice bread as compared to wheat bread and a lack of facilities (e.g. oven). The military dietitians had the highest levels of positive and active interest as well as intention and opinions toward using rice bread. On the other hand, the school and B & I dietitians had very positive perceptions of rice bread but did not actually apply it in their foodservice menus. Overall, the results of this study suggest that the development of diverse menus using rice bread along with government support of its use, including facilities with ovens as well as rice bread subsidies, should be carried out for on-going expansion of the rice bread supply.
The purposes of this study were as follows. First is to compare the importance of operational factors to determine types of school breakfast program, and second is to do the preference analysis of operation-related people depending on the attributes and levels of the operation of school breakfast program. The questionnaires developed for this study were distributed to 134 school dietitians, 114 school foodservice officials at the educational board, 68 staff members of foodservice contractors and 493 parents. Statistical data analyses were performed using SPSS/WIN 12.0 for descriptive statistics and conjoint analysis. The conjoint design was applied to evaluate the hypothetical foodservice types. According to the analysis on the attributes and levels of the school breakfast operation, the relative importance of each attribute was as followsprice (36.30%), menu (29.60%), foodservice staff (22.54%), serving type (11.55%) to school dietitians, price (34.99%), menu (28.15%), foodservice staff (23.52%), serving type (13.35%) to school foodservice officials at the educational board, menu (30.55%), price (30.24%), foodservice staff (28.75%), serving type (10.47%) to staff members of foodservice contractors and price (36.34%), menu (29.73%), foodservice staff (21.01%), serving type (12.92%) to parents. The results of the conjoint analysis indicated that the school dietitians and school foodservice officials at the educational board preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, 1~3 foodservice staff, with a price range of 1501~2000won, and tray serving. Staff members of foodservice contractors preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, 1~3 foodservice staff, with a price range of 2501~3000won, and tray serving. Parents preferred the school breakfast operation with 5 traditional menus per 5 day, 6~7 foodservice staff, with a price range of 2501~3000won, and tray serving. About a half of school dietitians considered that elementary schools were appropriate for the suggested school breakfast operation program. But, 68.2% of school foodservice officials at the educational board, 69.1% of staff members of foodservice contractors, and 38.1% of parents considered high schools to be the suitable model. Therefore, it indicated the need to recognize the different opinions among breakfast operation-related people and take these factors into consideration in developing the school breakfast program.
The purposes of this study were 1) to analyze the correlation between Word-of-Mouth(WOM) message sender credibility and WOM effect and 2) to analyze the differences of WOM message sender creadibility and WOM effect in off-line and on-line WOM communication. The messages were created as a form of scenario for this study. Respondents were asked to evaluate the message sender credibility and predict WOM behaviors after reading given scenario. The questionnaires were distributed to 200 customers and a total of 175 questionnaires were used for analysis(87.5%). The statistical analysis was conducted using SPSS Win(12.0) for descriptive analysis, paired t-test, factor analysis, correlation analysis. The positive off-line WOM message sender was considered as more credible(p<.001) than on-line WOM message sender. 'Message sender credibility' is correlated with 'attitude formation' in both channels, but 'reliable' factor of 'credibility' variable is not significantly correlated with 'attitude change'.
