Eight commercially packaged kimchi products were examined over 15 days of storage at $4^{\circ}C$ to evaluate the occurrence of Hafnia alvei (H. alvei). Additionally, 7 saeujeot products, as a possible ingredient source, were analyzed to examine the bacteria's origin. Over the storage period, kimchi samples had decreasing pH levels, which stabilized at pH 4.2; acidity increased to $0.9{\pm}0.1%$. Lactose-nonfermenting bacteria, which H. alvei belongs to, gradually reduced in numbers over the kimchi storage. However, the relative frequency of H. alvei to lactose-nonfermenting bacteria tended to increase. From the kimchi samples, 58 H. alvei-presumptive colonies were selected. Forty three colonies turned out to be H. alvei and 15 colonies were identified as other strains or uncertain identifications when the API 20E system was used. From further test, 3 of the 43 colonies were H. alvei (-) against the phage test. Finally, H. alvei was isolated from saeujeot, indicating that this ingredient can be an originating source of H. alvei in kimchi.

Studies based on food analysis or food databases use the national standard food database. Although Internet information services are increasing gradually, users are only able to get definitive and profitable information using standard food terms. Until now, it has been uncommon to find food retrieval services that include users' regional or historical characteristics. Thus, this study introduces a prototype for Food and Dish Synonym Retrieval (NutriSyn) that includes synonyms and related words. The environments which NutriSyn was implemented were Linux for the server operating system, the Microsoft Windows series for the users' operating system and Apache for a web server. The development languages used are PHP, JavaScript and HTLM with a MySQL database. Users can access NutriSyn using Internet browsers. The main menu items are (1) Food Synonym DB, (2) Dish Synonym DB, (3) Food Information DB, (4) Dish Information DB, and (5) Food and Menu Synonym Retrieval. This system is expected to be a useful tool for food experts and interdisciplinary research.

The purpose of this study was to determine the standard work time of dietetic staff through work sampling methodology in school flood service systems. Work measurement through work sampling methodology was conducted in five conventional, five commissary and five joint management flood service systems over two consecutive weeks in October 1999. Statistical analysis was performed on the SAS/Win 6.12 package program for Kruskal-Wallis test and multiple comparison. Observed data were satisfied with a confidence level of 95% and a confidence interval of $\pm$ 0.05. The results of this study can be summarized as follows. The actual time spent by dietetic staff members in conventional, commissary, joint-management flood servile systems was 2,394, 2,521 and 2,110 minutes per week, respectively. Transportation time of each flood service systeml and ILO allowance rate (11%) was applied. Thus, the standard work time per week of dietetic staff members in conventional, commissary, joint-management flood service systems was 2,746.14, 2,861.58 and 2,520.81 minutes, respectively. The standardized index was 1.04, 1.08 and 0.95 men in conventional, commissary, and joint-management flood service systems, respectively. Regardless of the school flood service system, those with "the duty of cooking and distribution management" had the longest labor time, while those with "duty of nutritional education" had the shortest labor time.

This study examined students' menu preferences as well as the job satisfaction and specific considerations concerning foodservice operation of dieticians and nutrition teachers at special schools for the disabled. Semi-structured interview questionnaires were sent to all of the 21 special schools with direct school food service in Gyeonggi-do, and 16 dieticians and nutrition teachers agreed to participate in this study. Among the various menu groups, the subjects perceived the meat group as the most preferred and the vegetable group the least preferred. They were generally satisfactory with their job and duty, and had a strong sense of belonging to the school. However, most of them answered that they needed more time for nutritional education and counseling. While most had pride and pleasure in their job, they expressed a desire to change the system to better fit with their roles as professional nutritionists. The content analysis revealed that the subjects mainly focused on safety issues in planning the food menu and were thus limited in selecting menu items. They also felt difficulty in menu planning due to various tastes and preferences, since special schools tend to consist of a wider grade range. However, most subjects reported little trouble in food distribution and food leftovers owing to practical support from teachers and parents. The necessity for education concerning table manners and obesity prevention was generally a shared opinion, and education programs for parents were also perceived as necessary to better understand the special considerations for developing proper eating habits in their child. The study findings provide useful basic data to improve the foodservice system at special schools.

The purpose of this study was to identify the difference of school food service dietitians' work value, job satisfaction, and turnover intention based on their expectation to be a nutrition teacher. Also, this study explored the differences in expectation to be a nutrition teacher, work value, job satisfaction, turnover intention depending on demographics and school foodservice operational characteristics. This study surveyed dietitians who worked at school foodservice in Kyunggii and Daegu Gyeoungbuk Province. A total of 509 responses were collected using on-site survey and online survey (59.3%). Dietitians expressed favorable work value ($3.88{\pm}0.34$) and mid level of a job satisfaction ($2.99{\pm}0.64$). The percentage of dietitians who had an intention to leave after the promulgation of a nutrition teacher system (13.2%) was lower than that of dietitians who had an intention to leave prior to it (23.2%). Most dietitians expected a salary rise (84.7%), more chance to teach nutrition education (76.0%), and the improvement of power not only as a teacher but as a dietitian (72.7%). Dietitians who had higher expectation levels to be a nutrition teacher (> 3 on the 5 point Likert scale) showed a higher tendency of significant turnover intention (F = 4.40, p < 0.01) and more confident work value (F = 15.292, p < 0.001) when comparing those who had lower expectations. There were significant differences in work value, job satisfaction, turnover intention, and expectation to be a nutrition teacher depending on career length and employment status of dietitians. This study revealed that school food service dietitians have favorable expectations to be nutrition teachers with high work value.

Purpose - As the competition in the foodservice franchise industry and the market becomes fierce and the entry barrier is lowered, the foodservice franchisor and franchisees strive to increase their competitive advantage in the market. Therefore, the franchisor and franchisees use experience management strategies to enhance the positive experiences of customers visiting the stores. In this regard, this study examines the effects of customer-oriented activities (physical-, social-, health-, and service-oriented activities) on utilitarian and hedonic values, and loyalty using stimulus-organism-response (S-O-R) model and value-expectancy theory. Research design, data, methodology - The data were collected from panels of online survey company, who visited a foodservice franchisee within last month. The survey was conducted for about 15 days from March 7, 2019 to March 21, 2019, and about 3,500 e-mails and messages were distributed to ask for the survey. A total 412 responded and completed the questionnaires. Of the 412 completed questionaires, 12 were discarded due to missing and misinformation data and 400 were retained for further data analysis. Results --The results showed that social oriented activities, health oriented activities, and service oriented activities had positive effects on hedonic value, while physical oriented activities did not have a significant effect on hedonic value. Health oriented activities and service oriented activities had positive effects on utilitarian value, while physical oriented activities and social oriented activities had no significant effects on utilitarian value. Hedonic and utilitarian values also have a positive effect on loyalty. Conclusions - First, food service franchises should provide services and menus in consideration of the health of customers. When a customer visits the store, franchisee should provide more health-oriented food or materials and clean and comfortable conditions so as not to threaten the health of the customer. Second, the food service franchise must build a service-oriented system. Foodservice franchisor need to provide continuous service training not only to the franchisees, but also to the employees of the franchisees. Third, franchise should design a store where customers can form social exchanges through providing various information exchange to customers and making the store as a local community center.

This study was conducted to investigate the utilization, recognition, and satisfaction of environment-friendly agricultural products (EAPs) in school food services according to the type of foodservice in the Jeonbuk area. Among the 270 school food service providers evaluated, 56.3% of the schools were located in an urban area and 43.7% were in a rural area. About 80% of urban schools used the EAPs for school foodservice, and 89.8% in rural schools (p<.05). The purchase frequency of grain (p<.01), fruits (p<.05), and processed foods (e.g. Tofu) (p<.001) was significantly different between the urban and rural schools. The perception of school dietitians in urban and rural schools between the EAPs and general agricultural products was significantly different (p<.05). The most different fact was 'safety' (p<.001). Most school dietitians has a gut understanding and a lot of confidence about the system of EAPs (p<0.01). The satisfaction score with EAPs was 3.35; in the urban schools it was 3.36 and in the rural schools 3.12 (p<.01). The satisfaction with EAPs in urban and rural schools was significantly different with regard to several factors; these were 'design' (p<.05), 'color' (p<.001), 'fresh' (p<.001), and 'diversity' (p<.01). There are conflicting views between the urban and rural schools for the additional costs brought by using EAPs (p<.01). In conclusion, our central and local governments should change their roles in financially positive ways and reflect the issue to make the policy effective.

The purpose of this study was to use the Kano model to compare and analyze the educational service quality attributes of domestic and foreign culinary arts schools. For this purpose, a questionnaire-based survey was completed by 312 students who were studying in domestic and foreign culinary schools. The results of the study indicated that 23 of the total 25 attributes were significantly different between domestic and foreign culinary arts school.; the "minium 4 hour-kitchen class" and "mandatory internship program" were classified into "indifferent quality" for domestic schools and a "must-be quality" for foreign schools; "well-organized internship guidebook", "kitchen class limited to 20 students", "introducing the latest food or restaurant trends", "library with the latest publications related to major", "objective instructor's evaluation", "detailed instructor's evaluation", "instructor's field experience", and "decent communication skills on the part of the instructor" attributes were classified into "attractive quality" for domestic schools and "must-be quality" for foreign schools; and "kitchen classes operated by block system", and "foreign instructors for each ethnic cuisine" attributes were classified into "indifferent" and "attractive quality" for both domestic and foreign schools, respectively. Also, according to the Better and Worse quotient designed by Timko, there were more attributes for domestic school than for foreign school that scored over 0.5 in the Better category and fewer attributes for domestic than the foreign scored over 0.5 in the Worse category. The results also indicate that, students in foreign schools receive an educational service of better quality than students in a domestic school. As a result, this research suggests significant implications to develop culinary educational services.
