The purpose of this study was to investigate whether a franchisor's influence strategies could affect a franchisee's relationship satisfaction, which in turn could affect their boundary spanning behaviors. The constructs of influence strategies included promise, recommendation, information exchange, request, threat, and legalistic plea. The boundary spanning behaviors were external representation, internal influence, and service delivery. The sample used for this research consisted of store owners or managers of franchisee restaurants in Korea. A total of 605 questionnaires were analyzed using SPSS/$PC^+$ and LISREL. Empirical research findings were that (1) promise, recommendation, and legalistic plea affected relationship satisfaction, and (2) relationship satisfaction influenced external representation, internal influence and service delivery. However, information exchange, request, and threat did not affect relationship satisfaction. Based on these findings, franchisors were recommended to provide motivations to franchisees if the former wants to receive help from the latter.

The purpose of this study was to analyze the effects of food neophobia on food choice motives, such as health concern, weight control, ethical concern, and vegetable consumption. A total of 290 questionnaires were completed. Moderated regression analysis was used to measure the moderating effects of food neophobia. Results demonstrated Model 3 to be the best fit, compared to Model 1 and Model 2. In Model 3, the effects of health concern and food neophobia on vegetable consumption were statistically significant (p<0.01). However, the effects of weight control and ethical concern on vegetable consumption were not statistically significant (p>0.05). As expected, the combination of health concern and food neophobia had a significant effect on vegetable consumption (p<0.05). However, weight control and food neophobia, and ethical concern and food neophobia had no significant effects on vegetable consumption (p>0.05). Moreover, health concern related to vegetable consumption was statistically significant at all levels of food neophobia, except, when level of food neophobia was high (p<0.001). In developing and testing moderated regression models, which integrate relationship among food neophobia, health concern, weight control, ethical concern and vegetable consumption in the future, this study may provide a deeper understanding of the complex relationship among vegetable consumption behavior-related variables.

Echinacea purpurea (L.) Moench (purple cone flower) is an important medicinal plant; it can enhance immunity, relieve pain, and reduce inflammation, and also has hormonal, antiviral, and antioxidant effects. Adventitious root biomass of Echinacea purpurea was produced in commercial-scale bioreactors for use as a dietary supplement in the food industry and in traditional medicine. Biosafety and toxicological evaluations of tissue-cultured Echinacea purpurea adventitious roots (TCEPARs) were performed. Reverse mutation and chromosomal aberration tests showed no significant mutagenicity. Furthermore, repeated four-week oral dose tests performed in Sprague-Dawley rats did not show any notable changes in the general behavior of the rats, in the gross appearance of their internal organs, or in their mortality rate. There were no differences between the control group and the treatment group in parameters such as absolute body weight, hematology, blood chemistry, and absolute and relative organ weights. These findings indicate that TCEPARs are safe and nontoxic when consumed at an average dietary level and can be used as raw material for traditional medicine and the food industry.

BACKGROUND/OBJECTIVES: This study aimed to compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students. SUBJECTS/METHODS: A total of 1,441 elementary, middle, and high school students attending 58 schools in Gyeonggi-do, South Korea participated in the survey in 2015. A questionnaire and informed consent forms for students and legal guardians were sent home and completed responses were returned to the researcher. RESULTS: Approximately 58% of the students perceived the portion sizes of school meals as appropriate and 76.1% consumed almost all or all of the meals served. More elementary and middle school students than high school students consumed almost all or all of the meals (P < 0.001). A regression analysis revealed that the students with a higher dietary behavior score (P < 0.001), higher satisfaction with food service (P < 0.001), a higher environmental protection practice score (P < 0.05), and more positive attitudes toward school meals (P < 0.01) consumed significantly more meals. The provision of foods that taste good and reflecting student opinions on menus were the most important factors for increasing school meal consumption. CONCLUSIONS: To increase consumption of school meals, food service staff should provide students with quality meals and engage students in school food service. Nutrition education that emphasizes healthy eating behaviors and cafeteria environment modification that applies strategies based on behavioral economics can encourage students to consume more school meals.

The food service industry has grown larger with changes in the economic and socio-cultural environment. In this saturated food service industry, generation X and MZ are the main consumer forces that demand attention. That is because a generation is the main psychographic factor that reflects personal values and lifestyle based on one's life cycle. From such a perspective, a generation in marketing has been used as a variable to predict a market by supplementing demographic factors. Accordingly, this study classified generations into generation X and generation MZ with the use of the 2019 consumer behavior survey for food by Korea Rural Economic Institute (KREI) and then investigated the factors influencing group and personal dining-out expenses. The analysis was carried out applying the Tobit model using SPSS and R. The positively influential variables on generation X's personal dining-out expenditure were male, single person, high income and simple lifestyle, whereas housewives, personal ethical consciousness, behavioral ethical consciousness, and safe dietary life were negatively influential variables. The positively influential variables on generation MZ's personal dining-out expenditures were male, dual-income, high education level, corporate and governmental ethical consciousness, while the number of family members and safe dietary life were negatively influential variables.

The purpose of this study was to compare body image and dietary behavior in middle and high school girls in the Gyeongbuk area in September, 2014. Data were collected from a total of 194 middle school and 170 high school girls through a self-reported questionnaire. A total of 364 completed questionnaires were collected and used for the final analysis. The mean body mass index (BMI) of respondents was normal at 21.29. Generally, high school girls had greater height, weight and BMI than middle school girls. Height (p<0.001) and weight (p<0.001) were significantly different, while BMI was not. The ratio of students who perceived their body size as 'Fat' was significantly (p<0.05) higher in high school (43.9%) than in middle school (31.6%). The ratio of dissatisfaction with their current body image was significantly (p<0.001) higher in high school girls (64.1%) than in middle school girls (44.0%). Among respondents who perceived their body size as 'Fat', many high school girls actually (53.3%) had normal or low body weight and this was significantly (p<0.001) higher than in middle school girls (39.3%). Experience with weight control was higher in high school girls (67.3%) than in middle school girls (60.6%), but there was no significant difference. Regarding the weight control methods, respondents selected 'combination diet and exercise' (22.2%), 'diet control' (20.9%), 'exercise' (18.7%), and 'reduce snacks and midnight snack' (17.4%). 15 items under obesity-related dietary behavior were measured with 5-point scales and lower scores indicated obesity diet behavior. The mean score for all respondents was 3.19/5.00, and high school girls (3.06) scored significantly (p<0.001) higher than middle school girls (3.33). Our study suggests that the development of effective nutrition and health education for diet control is crucial for adolescent girls. This study will enable educators to plan more effective strategies to improve the dietary knowledge of adolescent girls.

The handicapped frequently suffer from inappropriate food intake often resulting in overweightness, malnutrition, and poor growth and development. Our study was done on 7 to 12 year old mentally retarded children attending a special education school in Seoul. We administered questionnaire surveys and 3-day dietary recalls of the subjects, with help when needed from their stay-at home or their care-giving teachers. The questionnaires covered the general characteristics and dietary behaviors of the subjects. The degrees of handicap of the 142 children ranged from the trainable (54.9%), the educable (31.0%), and the non-trainable (14.1%). Of the children studied, 70.4% had ‘breakfast always’, which was higher than normal. Appetites were highest in the Down's Syndrome group. We found that the more serious the handicap, the higher the breakfast eating ratio and appetite level. The main reason for their missing breakfast differed according to the handicap level: ‘late rising’in the educable and non-trainable groups but ‘no appetite’in the trainable group. Most of the children (52.2%) spent less than 20 minutes eating their meals, the parents described their children's dietary habit problems as a pica (22:3%) or overeating (17.3%) , and they indicated that teaching the children how to use spoons and chopsticks (33.1%) was the most stressful. Actually more than 85% of the subjects could not use chopsticks, and skill of using cutlery was significantly different according to the degree of handicap. The food preference for milk products was the highest. It was interesting that the handicapped who had serious food pica didn't like food groups such as grains/starches, meats/fishes/eggs/beans or vegetables/fruits.
