BACKGROUND/OBJECTIVES: With the advances in technologies, self-service kiosks at foodservice operations are becoming a new way of service provision. This study examined the relationships among the menu information quality, nutrition information quality, technology acceptance characteristics, and customer behavioral intention toward the kiosks in fast food restaurants. SUBJECTS/METHODS: A survey with a self-administered method was distributed online and offline. The sample consisted of customers who had used the kiosks at fast food restaurants in the last six months prior to the survey. The study hypotheses were tested by applying structural equation modeling. RESULTS: Structural equation modeling revealed the positive impacts of menu information quality and nutrition information quality, technology acceptance characteristics, and behavioral intention toward kiosks at fast food restaurants. On the other hand, one hypothesis (Hypothesis 4) on the impact of nutrition information quality on the perceived usefulness was rejected. CONCLUSION: The study is the first to investigate nutrition and menu information at foodservice kiosks and relate them to technology acceptance. The study is very timely and adequate in the time of the 4^th industrial revolution. The critical importance of the presentation of nutrition information and menu information at the kiosks at fast food restaurants was verified. The academic and industrial implications of the study findings were discussed.

The principal objective of this study was to evaluate the perceived management performance and importance level of nutrition teachers by school administrators in the Chonbuk area. Self-administered questionnaires were collected from 142 school administrators. Statistical data analysis was completed using SPSS v. 12.0. Approximately 74.6% of the subjects were men. About 37% of subjects were principals, 33% were vice principals, and 35% were administrative directors, with over 60% aged 40~50 years(p<0.05). Among the 142 schools evaluated, 82.7% were located in urban areas and 17.3% were in rural areas. About 98% of the schools served meals in the dining room(p<0.05). Approximately 68% of the schools employed nutrition teachers and 33.4% had school dietitians(p<0.001). The result indicated that the overall importance level(4.24) was higher than the performance level(3.97)(p<0.001). In a survey of the degree of task performance by nutrition teachers, administrators regarded sanitation management was evaluated as the most important performance parameter(4.49), other management attributes as very important parameters(4.41), with nutrition counseling being much less important(2.76) and meal service being least important(3.29; except for classroom teachers). According to the title of the subjects, evaluations of administrative directors were lower than evaluations of principals and the vice principals. The results indicate that nutrition teachers should not only have meal service management as their main duty, but should also be involved in constructing a life-long health management system for students and teachers by conducting nutrition education and counseling, and should be active in the development of nutrition education programs and in the duties of sanitation management of school meals.

This study aimed to identify whether or not four service situations varying according to positive and negative combinations of physical evidence and functional service influence store image and purchase behavioral intentions of customers at bulgogi restaurants. The video-scenario technique was used for the study. Data were analyzed with the SPSS (Window 19.0) package using frequency analysis, one-way ANOVA, 2 by 2 factorial ANOVA, exploratory factor analysis, and multiple regression analysis to confirm the hypotheses. The combined effect of functional service and physical evidence influenced store image and purchase intention. In terms of seperate effect of physical evidence and functional service, the effect of employee service on store image was more powerful than that of physical evidence, even though the effect differed depending on the situation. Purchase intention was only influenced by functional service quality from employees under the four different scenarios. Thus, when opening a Korean restaurant, proper management of tangible evidence suitable to service, and the prices expected from local customers should be determined. Additionally, extremely high or low levels of physical evidence management should be avoided.

Protein-calories malnutrition is common among patients in the hospital. In particular, elderly patients with neurologic disorders has more risk of nutritional deficiency due to swallowing difficulty. Enteral tube feeding is more economical, physiological and immunological than parenteral nutrition for patients who have adequate gastrointestinal function. This study was conducted patients with neurologic disorders who received enteral nutrition at Asan Medical Center from February 1 to October 10, 2002. The control group (48 patients) were given traditional feeding methods 4 times a day while the treatment group (45 patients) were given improved feeding methods 3 times a day. We assessed nutritional status of patients and compared to both groups. We investigated body weight, serum albumin, hemoglobin, total lymphocyte count by means of nutrition markers. The objectives of this study is to reduce the time needed for nutritional requirement of patients without an increase in gastrointestinal intolerances. The results of this study are as follows: 1. Nutritional status of many patients in both groups were either malnourished or at risk for malnutrition. 2. The time to arrive to the nutritional requirements were 6.21 $\pm$ 0.35 days for the control group and 4.24 $\pm$ 0.52 days for the treatment group. The treatment group showed a significantly shorter amount of time. 3. The changes of the nutritional marker in the control group showed a significant drop in body weight, serum albumin and serum hemoglobin while the treatment group experienced a significant increase in body weight, serum albumin and total lymphocyte count. 4. Feeding intolerane such as diarrhea, high residual volume, ileus, nausea and vomiting were investigated. Diarrhea found in 25.1% (12 patients) of the control group and 22.2% (10 patients) of the treatment group and these findings are not significant.

The objective of this study is to investigate various jobs and foodservice environments, as well as work performances of school foodservice dietitians and nutrition teachers in accordance to the years of service in Daejeon and Chungnam provinces. A survey was conducted among school foodservice dietitians and nutrition teachers; a total of 415 from selected elementary, middle and high schools in the areas. In this study, we surveyed the participants and analyzed the current state of general characteristics, status of their job environments and foodservice environments by frequency, and the averages and differences in work performance with regard to 12 work parts and 57 works using one-way ANOVA and Duncan's multiple range test according to the years of service. Six parts among 12 work parts were significantly different in work performance according to the years of service. The 6 work parts were menu (nutrition) management, utensil recovery and management, sanitation management, foodservice administration & evaluation, dietary habit guide, and other works. The 11-15 years group ranked as the top on the total score and means of work performance. While the 16-years or more group, 6-10 years group, and under 5 years group followed consecutively. Correlation analysis between job or foodservice environments and work performances showed that work performances of school dietitians were mostly influenced by employment status, education level, and annual salary among the variables of job or foodservice environments. Other works, dietary habit guides and menu management were mostly influenced by variables of job and foodservice environments.

Objectives: The purpose of this study was to suggest the strategies for improvement of home-delivered meal services for the elderly, to identify reasons for recipients to get started with the services and to evaluate the attitude, acceptability and adaptation of recipients to the services from the perspective of life context. Methods: The data was collected through face-to-face in-depth interviews with eighteen low-income elderly recipients of home-delivered meals and analyzed using a qualitative research method. Results: The results were deduced as four themes which comprised of long-term vulnerable socioeconomic contexts resulted in entry to the services, conflicting acceptability to the services, passive adaptation to taking the services, and positive practices to cope with supplement free meals or other services. The service participation was initiated because of a combination of prolonged, vulnerable socioeconomic contexts, including poverty and unexpected life events such as diseases, disability, living alone, aging and unemployment. With regard to taking the services, conflicting acceptability was observed: positive aspects including saving living cost and good quality of meals, and negative aspects including lack of a tailored service and feeling of stigma. Although the recipients needed an individualized service, they did not express their needs and demands for the services and they accepted the unavailability as an accustomed, prolonged vulnerable socioeconomic context. With regard to lack of tailored services, either self-solution such as modification of eating patterns or community-based network and services were used. Conclusions: We suggest that a system to concretely identify recipients' attitude, acceptability and adaptation for home-delivered meal services should be developed in the establishment of a tailored nutrition support system for the low-income elderly.

This study investigated quality characteristics and antioxidant activity of beetroots after blanching. Beetroots were blanched in distilled water, 2% NaCl water, and 2% citric acid water at 100℃ for 3 minutes (the blanched group). The moisture content was highest in the control (CON) at 91.30% (p<0.05), and cooking loss was lowest in the water-blanched beetroot (BW) at 5.39% (p<0.01). Chromaticity decreased after blanching compared to CON (p<0.001). Total polyphenol contents (TPC) and total flavonoid contents (TFC) decreased after blanching, and as a result of comparing the True retention (TR) of the blanching treatment group, BW had the highest with TPC TR 91.22% and TFC TR 70.51%. DPPH and ABTS+radical scavenging activities were highest in the CON, and in the blanching group BW was highest scavenging activity. The total number of microorganisms in the CON group was 2.97 log CFU/g, whereas no microorganisms were detected in the blanched groups. Therefore, this study, blanching in water without additives is the most appropriate method for preserving physiologically active substances and nutrients in beetroots and inhibiting microbial growth.
