Development of Food Safety and Nutrition Education Contents for the Elderly: by Focus Group Interview and Delphi Technique: Jung Hwa Choi, Eun Sil Lee, Yoon Jin Lee, Hye Sang Lee, Hye Ja Chang, Kyung Eun Lee, Na Young Yi, Yun Ahn, Tong Kyung Kwak; Korean J Community Nutr 2012;17(2):167-181. Published online April 30, 2012; DOI: https://doi.org/10.5720/kjcn.2012.17.2.167

Our society is aging rapidly, and the number of elderly people who are in charge of purchasing and preparing foods at home is increasing. However, most the elderly have difficulty managing nutrition and food safety by themselves. The purpose of this study was to develop the necessary knowledge, through focus group interview and Delphi technique to establish a food safety and nutrition education program. The diet and educational needs of the elderly were surveyed through FGI. The education topics were decided by the Delphi technique. The education program consisted of a five week program, and the topics taught were 'Dietary Change for Healthy Life', 'Prevention of Food Poisoning in Everyday Life', 'Safe Food Handling for my Health', 'Healthy Dietary Life to Prevent Chronic Disease', and 'Safety! Nutrition! Healthy Dietary Life'. This education program was designed to decrease the perceived barriers, and to increase the perceived interests and the sense of self-efficacy. Education program materials, lesson plans, slides, handouts, videos, leaflets, and booklets were developed. Based on the results, the contents of the food safety guideline leaflets for the elderly were decided as the following: (1) wash your hands in the correct way; (2) select safe food; (3) cook foods safely; (4) keep foods safely; (5) keep kitchen utensils clean. In conclusion, if advanced education programs are implemented and delivered continuously in locations such as health centers and community welfare centers, those will contribute significantly to enhance the perception of food safety and to change the desirable dietary behavior of the elderly.

Clients' Handling and Consumption of Home-delivered Meals at Home and Their Perceptions on Home-Delivered Meal Services for Older Adults: Jung Yeon Park, Kyung Eun Lee, Na Young Yi, Tong Kyung Kwak; Korean J Community Nutr 2010;15(3):379-392. Published online June 30, 2010

Abstract PDF: The purposes of this study were to investigate recipients' handling and consumption of home-delivered meals at home and to assess their perceptions on home-delivered meal services for older adults. A total of 312 elderly people who received home-delivered foodservice were surveyed using an individual interview technique. A statistical data analysis was completed using SPSS (ver. 14.0). It was found that 90.2% (n = 166) of the lunch box recipients received services for six days per week, and 76.6% (n = 95) of the side-dish recipients got services once per week. More than half of the clients reported that they cooked meals by themselves on days when meals were not delivered. The two hundred thirty-two (75.3%) ate their meals as soon as they were delivered. It was found that 66.8% of the lunch box recipients and 7.3% of the side-dish recipients left delivered meals on the counter (at room temperatures) before eating. Only 11.4% of the lunch box recipients and 48.4% of the side-dish recipients kept delivered meals in the refrigerator before eating. Less than half of the lunch box recipients consumed all foods they were served at once. The reasons the recipients did not eat their all meals delivered at once were "saving for next meals" and "big portion size". Of those clients who left delivered meals, 19% of the lunch box recipients and 9.7% of the side-dish recipients ate leftovers without reheating. An average score of quality of delivered meal services was 3.5 out of 5 points. The results suggest that the clients of the home-delivered meal service should be provided information on proper handling and consumption practices with delivered meals at home. The findings of the study will be used to develop nutrition and food safety management guidelines for senior foodservice.

Food Waste Management Practices and Influencing Factors at Elementary School Food Services: Seoung Hee Kim, Tong Kyung Kwak, Eun Hui Choi, Kyung Eun Lee; Korean J Community Nutr 2007;12(6):815-825. Published online December 31, 2007

Abstract PDF: The study was designed to investigate food waste management practices and to identify factors affecting food waste generation at school food services. A total of 202 dietitians employed at elementary schools participated in the survey. The mean food waste weight per school was 77.54 kg, forty percent of the schools generated food waste of 50~100 kg every day and 53% generated plate waste less than 50 kg. Three quarters of the dietitians perceived plate waste as a major component of the food waste and vegetable dishes were a major source of the plate waste. Half of the dietitians used a food waste pick-up service for waste disposal, which was the most preferred waste disposal method. Approximately 90% of the dietitians conducted education on plate waste reduction for students but their perceptions on the effectiveness of the education was inconsistent. The contents were environmental issues (70.3%) and unbalanced food choice (56.7%). According to factor analysis based on performance score, solid waste management practices were grouped into 'information collecting and education', 'supervision of production process', 'cooperation with related groups', and 'control over production planning'. Practices appertaining to 'cooperation with related groups', 'information collecting and education' factor need to be improved. Dietitians should pay attention to 'recycle and reuse of left over' practice. Waste generation differed significantly by dietitians' ages and working experience. In order to reduce plate waste, more effective education materials and methods need to be developed and support from principals, teachers, and parents is necessary.

Efficiency Analysis of Contract-managed Business and Industry Foodservice Operations Using Data Envelopment Analysis: Kyu Wan Choi, Young Min Park, Seo Young Shin, Tong Kyung Kwak; Korean J Community Nutr 2007;12(2):178-188. Published online April 30, 2007

Abstract PDF: This study was performed to suggest a new efficiency measurement indicator is necessary for evaluating management efficiency of food service operations in contract-managed foodservice companies, to distinguish efficient food service providers and inefficient ones by measuring comparative efficiency among food service operations, and to provide guidance for effective management through showing benchmarking targets for improving inefficient food service providers. The subjects of this study were the 93 B&I foodservice Operations of a domestic contract food service company. The analysis was conducted using CCR model in DEA model. A software, 'Frontier analyst', was used for the analysis. Based on the results derived from comparison of efficiency evaluation classified by providers with use of DEA, it was possible to identify efficient food providers and inefficient providers, and subsequently provide benchmarking guidelines for improvement of the inefficient groups. In analyzing the differences between the results of DEA efficiency evaluation by detailed operation status of food service providers, there was significant difference of efficiency outcomes in terms of contract types, while there was no significant difference in terms of business condition.

Comparison of the Nutrition Knowledge, food Habits and Life Styles of Obese Children and Normal Children in Elementary School in Kyeong-gi Province: Hyun Ok Park, Eun Kyung Kim, Kyung Ah Chi, Tong Kyung Kwak; Korean J Community Nutr 2000;5(4):586-597. Published online December 31, 2000

Abstract PDF: The nutrition knowledge and food attitude of obese children were assessed and compared with their normal children counterparts to provide information for nutrition education programs. One hundred forty six obese children and 92 normal children from the fourth to sixth grade in Bucheon and Anyang elementary schools of Kyeong-gi Province were selected for the study. A multiple choice questionnaire, including 12 items of general nutrition knowledge and 13 items of weight control, were used to test the nutrition knowledge of children. The results of this study are as follows : 1) 57.5% of male and 40.9% of female obese children had experience with weight control, but the rate of correct answers on the nutrition knowledge test ranged from 53% to 58%, which does not show any significant difference between the two groups. The rate of correct answers on items conrerning 'general nutrition knowledge' and 'nutrition knowledge for weight control' did not show any significant difference among the two groups. 2) Obese male students showed a higher rate of correct answers(59.2%) on items of 'the proper food selection for obese children', compared with their counterparts and also obese female students showed a higher rate of correct answers(88.6%) on 'physical exercise', compared with their counterparts. 3) The rate of correct answers on nutrition knowledge of 'basic food groups', 'the functions of iron and vitamins', 'the concept of energy', and 'the principle of weight change' were lower than 40%. 4) The obese children frequently did not have breakfast, overate during lunch in many cases, and had low recognition on knowledge that was necessary to weight control. 5) Only 30.9% and 22.7% of male and female obese children replied that they would participate in weight control programs. However, 53.6% of males and 68.2% of females did not show any concern in participating the programs. From these results, it was suggested that it is necessary to motivate the obese to participate in weight-control program. When developing nutrition education programs for the obese, the contents of the questions that showed a low correct answering rates should be emphasized.

Perceived Performance of Sanitary Management of School Food Service Managers in the Seoul Area: Yu Kyeong Chong, Tong Kyung Kwak; Korean J Community Nutr 2000;5(1):100-108. Published online March 31, 2000

Abstract PDF: Seven constructs of sanitary management :time temperature, storage, cross-contamination, personal hygiene, equipment facility and documentation management were evaluated to investigate the perceived performance of sanitary management for school food service managers, Using a four-part questionnaire containing the seven constructs of sanitary management HACCP program, demographic information and characteristics of food service facilities participants rated their self-perceptions regarding sanitary management. Of the 550 possible respondents, 248(45.1%) completed the study. For the perceived sanitary manage-ment variables, the participants rated them between 2.66 and 4.16(5-point Likert scale). Temperature management presented the lowest performances while storage management showed the highest. The number of years of work experience of the food service managers and the serving location correlated significantly to sanitary management variables. Documentation management was also highly correlated to the other sanitary management constructs. The respondents ranked the managers leadership and professional knowledge regrading HACCP as most important, followed by the facilitys supporting equipment and human resources second, to successfully implement the HACCP system at the school food service facilites, Awareness of this study indicating low performance on temperature management suggests an active training program is needed for sanitary management of school food service.

Development of the Computer-Assisted HACCP System Program and Developing HACCP-Based Evaluation Tools of Sanitation for Institutional Foodservice Operations: Jaung Sook Lee, Hee Jung Hong, Tong Kyung Kwak; Korean J Community Nutr 1998;3(4):655-667. Published online October 31, 1998

Abstract PDF: The Computer-assisted Hazard Analysis and Critical Control Point(HACCP) program has been developed for a systematic implementation of HACCP principles in identifying, assessing and controlling hazards in institutional foodservics operations. The HACCP-based sanitation evaluation tool has been developed, based on the results of the computerized assisted HACCP program in 4 service sites of C contracted foodservice company, including 2 general hospitals with 650-beds, one office operation of 400 meals per day, and one factory foodservice of 1,000 meals per day. All database files and processing programs were created by using Unify Vision tool with Windows 95 of user environments. The results of this study can be summarized as follows : 1. This program consists of the pre-stage for HACCP study and the implementation stage of the HACCP system. 1) The pre-stage for HACCP study includes the selection of menu items, the development of the HACCP recipe, the construction of product flow diagrams, and printing the HACCP recipes and product flow diagrams. 2) The implementation of the HACCP system includes the identification of microbiological hazards, the determination of critical control points based on the decision tree base files. 3) The HACCP-based sanitation evaluation tool consisted of 3 dimensions of time-temperature relationship, personal hygiene, and equipment-facility sanitation. The Cronbach's alphas calculation indicated that the tool was reliable. The results showed that the focus groups rated the mean of importance in time-temperature relationship, personal hygiene, and equipment-facility sanitation as 4.57, 4.59 and 4.55 respectively. Based on the results, this HACCP-based sanitation evaluation tool was considered as an effective tool for assuring product quality. This program will assist foodservice managers to encourage a standardized approach in the HACCP study and to maintain a systematic approach for ensuring that the HACCP principles are applied correctly.
