Purpose: This study was performed to evaluate the importance and satisfaction of the selective attributes of delivery food and to analyze the factors affecting customer satisfaction. Methods: A total of 574 responses were collected from customers who had ordered delivery food for data analysis. Statistical analyses were conducted using the SPSS program (ver. 25.0) for frequency analysis, χ2 tests, t-test, factor analysis, Pearson correlation, multiple regression analysis, and Importance-Performance Analysis (IPA). Results: The importance of delivery food selection attributes was higher in the order of 'hygiene control level (4.72)', 'taste of food (4.64)', and 'delivery accuracy (4.40)'. Satisfaction assessment was higher in the order of 'taste of food (4.32)', 'delivery accuracy (4.26)', and 'convenience of using the delivery app (4.21)'. According to the results of IPA, items that were priorities for improvement were charges for delivery, discount offers, sufficient description of the menu, and rapid handling of customer complaints. On an average, overall customer satisfaction score of delivery food was 4.01 out of 5 points. Additionally, five satisfaction factors were extracted by exploratory factor analysis. According to the results of multiple regression analysis, quality of delivery platform (p < 0.001), quality of delivery service (p < 0.001), convenience and diversity (p < 0.001), quality of delivery food (p < 0.001), and health and safety (p < 0.001) had significant positive effects on overall customer satisfaction. Conclusion: To increase customer satisfaction among delivery food customers, restaurant or delivery platform managers should consistently improve not only the quality of the delivery platform but also the quality of the delivery food and service.

Kimchi and soup/stew samples were collected from Korean restaurants in the Jeonju area and their salinity levels were analysed. Restaurant owners were also surveyed to assess their salt acceptability and attitudes. The average salinity of the Kimchi samples was 2.0${\pm}$0.4% and that of the soup/stew samples was 1.0${\pm}$0.3%. The average salinity of the soup samples was 0.9${\pm}$0.2% and that of the stew samples was 1.1${\pm}$0.3%, and the average salinity of the stews was significantly higher than that of the soups (p<0.001). The average salinity of bean-paste soups was 0.9${\pm}$0.2% and that of clear soups was 0.8${\pm}$0.2%, in which the average salinity of the bean-paste soups was significantly higher than that of the clear soups (p<0.05). When asked about the saltiness of their side dishes, soups/stews, and Kimchi, the largest number of owners answered 'ordinary'. About 50.4% of the owners also answered 'ordinary' for their salt acceptability, and 59.8% answered that their customers have 'ordinary' salt acceptability. However, a significantly higher ratio of owners in the group whose Kimchi samples had low salinity answered that their customers' salt acceptability was for 'flat' foods as compared to the group whose Kimchi was of high salinity (p<0.05). About 45.7% of the owners answered that 'they participated in controlling the saltiness of all their dishes', and 40.2% answered that 'they considered the traditional saltiness of their menu items as more important than the saltiness acceptability of their customers.' Also, 82.7% of the owners answered 'they made the Kimchi themselves.' The types of frequently served soup were clear soup, such as bean-sprout soup and seaweed soup, followed by bean-paste soup and thick beef soup, in order. The types of frequently served stews were Gochujang stew with frozen pollack or croaker, bean-paste stew, and clear stew.

The purpose of this study is to suggest management strategies for both upscale hotel buffet restaurants and independent buffet restaurants by conducting an IPA(Important-Performance/satisfaction Analysis) on the selection attributes for buffet type restaurants. Additionally, the effects of the selection attributes' satisfaction on the "intention to recommend" was tested. Surveys were conducted from April 15th through May 4th, 2016 by using both SNS and off-line surveys of consumers with buffet restaurants dining experiences within the previous year, of which a total number of 160 questionnaires were used for the statistical analysis. The result showed a few different selection attributes in each quadrant; additionally, food quality and menu had positive effects on the "intention to recommend" for hotel buffet restaurants, while food quality was the only selection attribute with positive effects for independent buffet restaurants. Based on the results of the study, it can be suggested for the hotel buffet restaurants to constantly develop new and unique menu items to lead the needs of the fast changing consumers of today instead of focusing on the premium characteristics of upscale hotels and their brand names. In addition, offering a variety desserts seems to be something to re-consider for both types of buffet restaurants.

The purpose of this study is to compare conditions of Korean Restaurants in Hong Kong with those of Thai ones, which have already succeeded in globalization, by investigating and analyzing the characteristics of the two parties in Hong Kong, a world-wide international city. For these purposes, we selected 10 Korean restaurants & 10 Thai restaurants in Hong Kong, and visited the selected restaurants during the period from 2007.7.9 to 2007.7.14, to examine indoor spaces and food-related elements were recorded in detail, photographed and analyzed. The results of study is as follows ; we have first found that Korean restaurants did not show any humane properties linked to restaurant concepts and indoor space, did link Korean images through their trade names, and showed decorative culture based on traditional house and dietary-life cultural properties based on traditional Korean Bansang table setting at large. On the other hand, 4 (22.5%) out of the entire cases in Thai restaurants showed religious characteristics with strong Buddhist colors revealed, and all cases showed traditional Thai food cultures, from which we could find out dietary-life cultural properties. Second, whereas there were one case of Korean restaurants in which tradition was main and modernity was assistant, five cases in which tradition and modernity were paralleled in value, and two cases in which modernity was main and tradition was assistant, Thai restaurants had one case where tradition was main and modernity was associative, four cases in which tradition and modernity were paralleled in value, and four cases where modernity was main and tradition was assistant. This means that the Thai restaurants did not insist only on tradition, but showed efforts to transmit luxurious and refined Thai images to people from the world. Third, whereas Korean restaurants had to do with all kinds of menu, were equipped with brazierson their tables uniformly, and showed any differences because they did not use different tableware in accordance with foods, Thai restaurants divided the dinner into the hors d'oeuvre, the main, and the dessert or systemized menu structure by categories in accordance with cooking styles, and tableware selection in accordance with menus, table setting, food materials, and food styling using flowers were consistently expressed.

Purpose: The purposes of this study were to investigate eating behavior of university students through social commerce and to analyze factors affecting university students' attitude regarding social commerce. Methods: Questionnaires were distributed to 445 university students in Changwon, Korea from March 28 to April 28, 2013. A total of 339 questionnaires were used for the final analysis, which excluded improperly-completed questionnaires. Results: The major factor considered for eating behavior through social commerce was price (37.2%). Purchasing experiences of foodservice products according to types of foodservice were 64.9% for coffee shop, 59.3% for fast food restaurant, 53.4% for family restaurant, 46.0% for specialty restaurant, 35.7% for pizza restaurant, 35.4% for buffet, and 31.9% for bakery. Factors affecting satisfaction with social commerce for purchasing foodservice products were 'service quality of foodservice company', 'communication of social commerce', and 'discount rate of social commerce'. Factors affecting repurchasing intention of foodservice products through social commerce were 'service quality of foodservice company', 'site design of social commerce', and 'discount rate of social commerce'. Conclusion: In order to increase satisfaction with social commerce, 'service quality of foodservice company', 'communication of social commerce', and 'discount rate of social commerce' should be increased. And, to increase repurchasing intention of social commerce, 'service quality of foodservice company', 'site design of social commerce', and 'discount rate of social commerce' should be increased. In addition, two factors 'service quality of foodservice' and 'discount rate of social commerce' were found to have an effect on satisfaction and repurchasing intention of social commerce. For development of social commerce and foodservice industry, cooperative relationship between social commerce and foodservice industry is needed, and a reasonable price strategy should be established. The university students considered price as a major factor of eating behaviors and did not consider menu and taste as a major factor. From a longer perspective, such an eating behavior would have an effect on university students' dietary life and it would cause nutrition and health problems for university students. Thus, it implied that further studies from the perspectives of nutrition and health regarding eating behavior through social commerce service should be conducted.

To achieve these goals constituent dimensions and structural elements of the Japanese restaurants service quality are being investigated through the review of the food service industry and service. The survey about the importance and the Japanese restaurants was also conducted with a questionnaire to identify the tendency of customers who visited restaurants. These results and satisfactions hypotheses are being tested in the restaurant and the empirical research aye both conducted to achieve time research purposes. Japanese restaurants, located in the metropolitan area, are being selected as the object limits of the survey. Eighty-seven questionnaires are being distributed three kinds restaurants which means total 250 for all, and from which 230 are being analyzed. Frequency and $\chi$$^2$test were applied for the general matters and the conditions of object while Cronbach's Alpha coefficient and factor analysis were applied for reliability and validity. t-test was attempted to fine the importance and the satisfaction of the service quality. Also ANOVA was utilized. After examining the results of this survey, few facts were apparent. First the number of male ana female customers in the Japanese restaurants are divided evenly in about 55% of male customers and 45% of female customers. However, these people have a wide variety of jos. Another evident fact present on this survey shows that customers eating at a less expensive restaurants have a income of 1,000,000 won where as the expensive or high-end restaurants have customers with higher income than average. The price sensitive customers studied in this survey shows that they spend on average 30,000 to 70,000 won per person in the less expensive establishments. Therefore, with some service quality restructuring, application of new systems and ideas these restaurants could efficiently maximize their profit margin. Customers also showed that lower prices in lunch time would be an appealing incentive to deviate from standard lunch time 〈12:00~13:00〉and menu specials would be of interest to deviate from busy dinner time. In conclusion, since restaurants in the middle range category are not so many restaurants in lower range have a chance to maximize their profit. This study clearly shows that even the lower-end restaurants could raise their profit margin by incorporating new marketing techniques and by improving the service level of their restaurants.

This research was performed to evaluate the effects of nutrition education on food waste reduction at school food service. A dietitian conducted nutrition education on environmental protection and proper eating attitude and poor eating habits for 3rd and 5th graders at an elementary school in Seoul. The effectiveness of the education was evaluated by surveying the students before and after the education; 375 responses were analyzed. A questionnaire was designed to compare changes of the students' attitudes and plate waste before and after education. Plate wastes of boiled black rice(p<0.05), potato soup(p<0.05), amaranthus herb salad(p<0.01), and cabbage kimchi(p<0.05) decreased significantly after education. Students' eating attitudes improved significantly(t= -6.22, p<0.01) after nutrition education. Major reasons the students did not eat all foods they were served were large portion sizes (30.59%), low menu preference (29.79%), and tastes (17.82%). The menus with high plate waste rates were cooked vegetable items (35.64%) and soup items (26.6%). After education, students' attitudes on ‘food waste pollutes the Earth(p=0.013)’, ‘food preparation for birthday parties(p<0.01)’, and ‘restaurant selection for eating out (p<0.01)’ changed significantly. After education, plate waste and portion sizes that the students perceived were not negatively correlated. In conclusion, nutrition education on proper eating habits and source reduction is an effective method to reduce food waste generation and to improve students' eating attitudes and awareness on environment.

This study analyzed the current status of registered patents related to food tech in Korea and Japan. Using the patent information search services of Korean and Japanese Patent Offices, patents registered during the past 10 years from January 1, 2005 to December 31, 2015 were searched with the following key words/phrases: "food or meal or diet" and "program or information system". A total of 669 patents (539 for Korea and 130 for Japan) were finally selected and analyzed. Based on Porter's value chain theory, the patents were categorized into three dimensions related to "manufacturing/processing/distribution", "sales & marketing", and "consumer support". The results showed that in Korea, 41.7% of the total patents were related to sales & marketing followed by consumer support (37.3%) and manufacturing/processing/distribution (21.0%). In Japan, patents related to consumer support accounted for 56.2% followed by manufacturing/processing/distribution (32.3%), and sales & marketing (11.5%). In the area of manufacturing/processing/distribution, "food quality management system" in Korea, and "food manufacturing and processing management system" and "food safety control and hazard analysis system" in Japan tended to show a significantly higher proportion of patents registered (p<.05). Under sales & marketing, patents in the categories of "food purchase and delivery service system" in Korea and "restaurant information sharing system" in Japan tended to be more frequently registered (p<.05). Finally, in the area of consumer support, "kitchen facility and cooking device control system" in Korea and "menu and nutrition management system" in Japan tended to account for a significantly higher proportion of patents registered (p<.001). The results are expected to provide useful insights into the development of new patents and markets for food tech in the future.

The purpose of this study was to look into how alliance discount cards affect customers using family restaurants by analyzing and identifying the difference in brand equity and satisfaction according to the propensity of using alliance discount cards. For this purpose, 407 customers who have used family restaurants completed a questionnaire survey. The study findings indicated that (1) there were significant differences in brand equity and satisfaction according to the propensity to use alliance discount cards. Moreover, it was found that groups with a strong propensity to use alliance discount cards had higher brand equity and satisfaction than groups that did not; also, (2) it was found that there were significant differences in brand equity and satisfaction according to the intensity of dependency on alliance discount cards. The group with strong loyalty to alliance discount cards went beyond the level of strong propensity to use alliance discount cards, of preference, and of use, which were previously proposed. This study implied that from mid-to long-term perspectives, it was necessary to operate a policy for more active alliance discounts as well as to ensure sufficient options for partnership benefits. Furthermore, it was essential to maintain the menu and service quality of restaurants, which were intrinsic factors for elevating brand equity and satisfaction in restaurants among dining customers.
