The purpose of this study was to investigate the food service status of community child care centers in Busan. A survey was conducted from November 1, 2012 to November 30, 2012 using questionnaires. Overall, 66.7% of the community child care centers had a separate dining room. The satisfaction score of the kitchen facility was 4.32 and the satisfaction degree of the dining place was 3.95. Most of the community child care centers were not managed by professionals and the food service was in a relatively poor status. In 61.3% of the community child care centers, the director of the center purchased the foodstuffs. In addition, approximately 72% of the child care centers directly purchased foodstuffs. When preparing meals, nutrition (73.0%), cost (13.5%), and preference (4.5%) were considered as the important factors for respondents. Overall, there were demands for increasing meal costs and improving the food service facilities. In addition, a higher degree of hygiene management resulted in a higher degree of satisfaction from children. Therefore, to improve food service performance at community child care centers, food services should be assisted by professionals and the person in charge of foodservices should be educated food service management.

Hemodialysis (HD) patients face a common problem of malnutrition due to poor appetite. This study aims to verify the appetite alteration model for malnutrition in HD patients through quantitative data and the International Classification of Functioning, Disability, and Health (ICF) framework. This study uses the Mixed Method-Grounded Theory (MMGT) method to explore various factors and processes affecting malnutrition in HD patients, create a suitable treatment model, and validate it systematically by combining qualitative and quantitative data and procedures. The demographics and medical histories of 14 patients were collected. Based on the theory, the research design is based on expansion and confirmation sequence. The usefulness and cut-off points of the creatinine index (CI) guidelines for malnutrition in HD patients were linked to significant categories of GT and the domain of ICF. The retrospective CIs for 3 months revealed patients with 3 different levels of appetite status at nutrition assessment and 2 levels of uremic removal. In the same way, different levels of dry mouth, functional support, self-efficacy, and self-management were analyzed. Poor appetite, degree of dryness, and degree of taste change negatively affected CI, while self-management, uremic removal, functional support, and self-efficacy positively affected CI. This study identified and validated the essential components of appetite alteration in HD patients. These MM-GT methods can guide the selection of outcome measurements and facilitate the perspective of a holistic approach to self-management and intervention.

Objectives: The purpose of this study was to examine the food allergy-related knowledge, awareness, and performance of dietitians at children's hospitals, depending on whether or not they have a clinical dietitian certificate. Methods: A questionnaire survey was administered to 41 dieticians at children's hospitals registered as a part of the Korean Hospital Association. The survey consisted of questionnaires examining general characteristics, nutritional counseling-related characteristics, and food allergy-related characteristics (food allergy-related knowledge, awareness, and performance). We examined differences according to the status of clinical dietitian certification. Results: The proportion of subjects who were holders of clinical dietitian certificates was 48.8%. There were differences between holders of clinical dietitian certificates and non-holders as follows. Regarding nutritional awareness and performance, 'needs to provide nutrition counseling in children's hospitals', 'providing nutrition counseling services in working hospitals', and 'whether there is a nutrition counseling room' scored higher among holders of clinical dietitian certificates than non-holders. Holders of clinical dietitian certificates showed higher scores for knowledge of food allergy symptoms and food allergy management than non-holders. For food allergy awareness and performance, 'self-assessment of food allergy knowledge understanding level', 'awareness of open oral food challenge (OFC)', 'recognition of the need for education and counseling on food allergy for patients / guardians', and 'food allergy related educational experience' scored higher among holders of clinical dietitians certificates than in non-holders. Conclusions: Children's hospital dietitians with a clinical dietitian certificate showed high knowledge, awareness, and performance related to food allergies. It is thus necessary to employ a clinical dietitian for food allergy management in children's hospitals. In addition, training and conservative education are necessary for the management of food allergies for children's hospital dietitians.

To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.

This study aims to develop a deep learning model to monitor rice serving amounts in institutional foodservice, enhancing personalized nutrition management. The goal is to identify the best convolutional neural network (CNN) for detecting rice quantities on serving trays, addressing balanced dietary intake challenges. Both a vanilla CNN and 12 pre-trained CNNs were tested, using features extracted from images of varying rice quantities on white trays. Configurations included optimizers, image generation, dropout, feature extraction, and fine-tuning, with top-1 validation accuracy as the evaluation metric. The vanilla CNN achieved 60% top-1 validation accuracy, while pre-trained CNNs significantly improved performance, reaching up to 90% accuracy. MobileNetV2, suitable for mobile devices, achieved a minimum 76% accuracy. These results suggest the model can effectively monitor rice servings, with potential for improvement through ongoing data collection and training. This development represents a significant advancement in personalized nutrition management, with high validation accuracy indicating its potential utility in dietary management. Continuous improvement based on expanding datasets promises enhanced precision and reliability, contributing to better health outcomes.

This study was performed to improve the hospital food service in quality and customer satisfaction by using 6-sigma strategy which was processed by DMAIC methods. The research procedure was as follows; analyzing the main causes of customer dissatisfaction of food service by using numerical method, and then finding out the standardized problem solving methods, and finally reforming food service process. The effectiveness of 6-sigma activity was measured by ‘food service quality index’, ‘customer satisfaction index’ and ‘total food service satisfaction index’. Food service quality index was calculated by adding grade of soup temperature, food service, delivery time, and setting accuracy. Statistical data analyses were completed by using the Minitab Ver. 14. By performing 6 sigma activity, food service quality index was increased from 67 to 79 points (p<0.05) and customer satisfaction index also rise from 73 to 79points (p<0.05). Satisfaction of meals’ taste, diverse menu, food setting accuracy, remove of food service, overall food service were significantly improved(p<0.05). The results of capability analysis in food service quality index, customer satisfaction index, and total food service satisfaction index were improved 2.11$\sigma$ to 2.49$\sigma$, 1.88$\sigma$ to 2.43$\sigma$, and 2.04$\sigma$ to 2.47$\sigma$ respectively (p<0.05). Therefore this study showed that subjective food service improving process could be measured by objective numerical value which might be used for financial value in hospital management.

In the present study, we conducted in-depth interviews with school dieticians and nutrition teachers to determine the local foods they were aware of and their experiences with local foods. We also aimed to obtain more detailed measures for local food vitalization and suggestions for improvements. In-depth interviews were performed with 8 school dieticians and nutrition teachers, who stated that local food vitalization was needed for school food services, because it could be a foundation for securing safefood products, student healthi mprovements, environmental protection, and the establishment of a general consumption market. However, they were aware of a higher number of disadvantages than advantages in school situations and indicated the deterioration of the quality of food products as the biggest disadvantage. The most-suggested measurement items for local food vitalization in schools included improvement of the food distribution system, expansion of education, information sharing, prevention of monopolies, improvement of food-product quality, and mass production. In addition, it was suggested that school dieticians and nutrition teachers should invest efforts in the development of excellent recipes and varied diets utilizing local foods. Therefore, system supplementation is urgently required in order for school food service officials, and consumers, to efficiently introduce and vitalize local foods. It is also necessary to foster an environment that encourages trust-based relationships with producers to maximize the effect of system supplementation. This would be the foundation for improving the health of students, improving food-service quality, nutrition management, and vitalization of the regional economy in the future, and will positively affect students' food consumption patterns even after they become adults.
