This study was carried out to investigate the perception on nutrition labeling of the processed foods among elementary school teachers in Busan. The survey was conducted from November 1 to November 30, 2008 by questionnaires and data which were analyzed by SPSS program. The results are summarized as follows. Ninety five point seven percent of the male teachers and 98.2% of the female teachers recognized the nutrition labeling (NL). The necessity of a NL system and comprehension of NL were higher in the female group than the male group. NL was trusted by 22.9% of male teachers and 19.7% of female teachers. The main reason for checking NL of the teachers was for food safety. For the most important NL items at purchasing the food, the teachers replied 'trans fatty acid' and 'cholesterol'. Five point seven percent of male teachers and 17.0% of female teachers were educated for NL. Seventy two point nine percent of males and 91.0% of females recognized the necessity of NL teaching. It is necessary to prepare education programs for both teachers and students about accurate recognition of NL. (Korean J Community Nutrition 14(4) : 430${\sim}$440, 2009)

The purposes of this study were to assess the nutrition service importance and performance level in views of industrial employees and to explore the ways to improve the nutrition service quality. A survey of industrial foodservice operations scatterly located in Korea was undertaken and detailed information was collected from each, including surveys of 1,002 industrial employees. Statistical data analysis was using SAS PC 6.04 for descriptive analysis, t-test, and analysis of variance. The whole industrial employees assessed the importance and performance of the dieticians' role on nutrition service as '4.03' and '3.32' out of 5 respectively, which suggests that the industrial nutrition service needs to be improved. The variables which received higher scores than the average mean were safe meal provision, sanitation management and equipment & facilities management, whereas the score of individual nutrition counselling was low compared to other variables of nutrition service. Dietician's performance level scored by industrial employees was statistically correlated with the effect of industrial foodservice(p<0.01). The groups who scored low performance were characterized by labor work, experience with less than 10 years, single, aged below 29 years old, and female.

The purpose of this study was to investigate nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, flood habits and their correlation to supplement use in middle-aged and elderly Koreans. A nationwide survey was conducted in the metropolitan areas (6 cities) and middle-sized cities (8 cities) of Korea from October to December, 2000. Subjects were randomly selected based on population, and 2,188 non-institutionalized adults aged over 50, and elderly (male 765, female 1,423) were studied. Data were collected using a standardized questionnaire administered in personal interviews. Nutrition and health-related scores of nutritional risk factors, perceptions on nutrition and health, nutritional knowledge, and flood habits were significantly higher in supplement users as compared to non-users. There was a negative correlation between nutritional risk factors and other nutrition and health-related scores on perceptions on nutrition and health, nutritional knowledge, flood habits, and pocket money. Also there was a positive correlation between nutritional risk factors and age. Therefore, these results may provide basic information for proper supplement use by middle-aged and elderly koreans.

The purpose of this study was to develop a standardized job description for dietitians using the DACUM technique. To examine the validity of job description through DACUM, dietitians were surveyed relative to importance, performance, and difficulty. The survey was conducted April 1-30, 2014. A total of 217 questionnaires were used in the analysis. The final developed job description for dietitians included six duties, 38 tasks, and 210 task elements. DACUM's findings include six duties: nutrition management, food service operation management, hygiene safety management, community food and nutrition program management, organization management, and professionalism strengthening. There were 5.1 points regarding importance, 4.1 points regarding performance, 4.9 points regarding difficulty, and statistically significant differences (p<0.001). Dietitians responded that 'nutrition management' and 'hygiene safety management' were the most important. 'Hygiene and safety management' showed the highest performance, and 'community food and nutrition program management' and 'professionalism strengthening'' showed the highest difficulty. Thus, it is considered that the job analysis results can be used to evaluate and improve the subjects' training program. Dietitians' jobs are subject to various environmental changes, such as demographic changes, health care system changes, and the development of the food industry, and thus, should be reviewed and analyzed periodically.

Purpose: In this study, factors of metabolic syndrome and nutritional status were examined according to gender and occupations using the 2013 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: This study was conducted on 1,750 workers (male : 892, female : 858) aged between 30 and 64, who participated in a health survey, health examination, and nutrition survey using the 6th 2013 KNHANES. Occupations were classified into white collar and blue collar workers, and nutrient intake was analyzed using a food frequency questionnaire. Analysis of complex sample design data through SPSS 19.0 was used for analysis. Results: The prevalence rate of metabolic syndrome among blue collar (35.1%) was higher than that among white collar workers (26.8%) in male subjects (p < 0.05) as well as in blue collar (24.8%) compared to white collar workers (8.9%) in female subjects (p < 0.001). Intake frequency per week, considering one portion by food category, showed significant differences in cooked rice (p < 0.05) and bakeries and confectioneries (p < 0.05) in make workers as well as stew and casserole (p < 0.01) and fruits (p < 0.05) in female workers. With regard to nutrient intake by occupation and gender, white collar workers consumed a greater amount of nutrients (not including total energy intake) compared to blue collar workers in both male and female workers. With regard to nutrient adequacy ratio (NAR) and mean adequacy ratio (MAR) according to gender and occupation, white collar workers showed higher numbers than blue collar workers in both male and female subjects. Conclusions: This study examined the prevalence rates of metabolic syndrome and nutrient intake according to gender and occupation. In both male and female subjects, blue collar workers showed higher prevalence rates compared to white collar workers, and their diet quality was worse than white collar workers' diet quality. Considering this result, customized nutrition education according to gender and occupation should be provided to workers to prevent diseases.

Objectives: This study evaluated the nutritional status and prevalence of metabolic syndrome of the people who participated in the KNHANES according to the number of household members. They were assessed by using information from the 2013~2014 Korea National Health and Nutrition Examination Survey (KNHANES). Methods: A total of 6,088 persons aged 19 years and over participated in 2013~2014 KNHANES, and they were classified into three groups according to the number of household members (single-person, two-person, three-person & over). The dietary behavior, nutritional status, health-related factors and the prevalence of metabolic syndrome of the subjects were investigated with using information from the survey questionnaires of KNHANES. The nutrient intake data of the subjects were obtained by the 24-hour recall method and this was analyzed for evaluating the nutrition adequacy ratio and the index of nutritional quality. The prevalence of metabolic syndrome among the subjects, and according to the study groups, was estimated using the blood and physical measurement data of the subjects. Results: As for EQ-5D index available for all the health states generated by the EQ-5D descriptive system, the single-person household member was the lowest among all the household types. The index of nutrition quality for protein, crude fiber, calcium, phosphorus, potassium, riboflavin and vitamin C in the single-person household was lower than that of the two-person or the three-person and over households (p<0.001). The mean adequacy ratio of single-person households was significantly decreased compared with that of the other types of households (p<0.001). The prevalence of metabolic syndrome was higher in the single-person households than that in the multiple-person households (p<0.001). Conclusions: These results showed that dietary behaviors, nutrition status and health status might be influenced by the number of household members. The results from this study would be useful for improving Korean people's dietary life and health status by implementing evidence-based, specialized intervention for the members of diverse types of households.

The purpose of the study was to examine job satisfaction, work performance, work satisfaction, perceived needs and self-evaluation of knowledge and skills of nutrition teachers. Survey questionnaire was administered to 106 nutrition teachers in schools of Gyeonggi area. Subjects were categorized into high- or low-job satisfaction group, and study variables were examined by job satisfaction group. Overall job satisfaction was high, with a mean score of 14.9 out of 20. High-job satisfaction group had more favorable perception regarding human relations and workplace atmosphere compared to the counterparts (p < 0.001). Work performance, examined by 12 items, was not significantly different between the two groups. However, satisfaction regarding specific work of nutrition teachers was significantly different by job satisfaction (p < 0.001). High-job satisfaction group responded that they had more knowledge and skills in areas such as food purchase management, food sanitation and safety management, equipment and facility management, nutrition education, nutrition counseling (p < 0.01), and general management & marketing (p < 0.05). High-job satisfaction group also indicated that nutrition teachers need to have more knowledge and skills than the counterparts, regarding food purchase management (p < 0.001), nutrition education (p < 0.01), nutrition counseling, general management and marketing, and teaching practices (p < 0.05). In addition, study results showed significant positive correlations among study variables. This study suggested that job satisfaction of nutrition teachers might be increased by having favorable human relations and workplace atmosphere, increasing satisfaction with specific work of nutrition teachers, and by increasing the knowledge and skills required for the work of nutrition teachers.

This study surveyed 266 housewives residing in a Gyeonggi-provincial area for their dietary attitudes, dietary habits, nutrition knowledge, and application of nutrition information to daily life according to whether they use nutrition labeling. The survey on the dietary attitudes of the subjects showed that the points of "think that nutrition affects health", "quite interested in nutrition and health information", "like developing and trying new diverse recipes", and "persistently try new foods" were higher among those who check out nutrition labeling (Check group, n=112) than those who do not check out nutrition labeling (No check group, n=154). Reason for snacking, the Check group reported higher in the reasons of "for taking nutrients" but lower in the reasons of "do not eat enough meal" and "impulsively" than the No check group (p<0.01). Asked about why they check the nutrition labeling, the Check group answered "to compare products with each other" and "to purchase healthy food" whereas the No check group said "to decide whether the food is safe or not" and "to reduce body weight" (p<0.01). The Check group showed more recognition on the significance of the nutrition labeling and application to their actual daily lives than the No check group. Therefore, our results suggest that proper use of nutrition labeling is expected to improve dietary attitudes and dietary habits as well as enhance the application of nutrition information to actual daily life and promote health not only for the housewives but also for their family members as well.

This survey was carried out to investigate the effects of dietary attitude on the nutrition knowledge, food habits and the intake of instant food, convenience food and fast food between two groups of college women, a nutrition major group and nutrition non-major one. Questionnaires were completed by 214 nutrition majors and also by 145 non-majors. Nutrition majors showed better average in meal time regularities per week than nutrition non-majors. And nutrition non-majors had a higher frequency rate in taking of instant food and fast food than nutrition majors. In the case of both college women, those who take a meal regularly at each meal times have a higher score in food habits. The women who ate instant foods more frequently got a lower score in food habits, bot the frequency of the intake of instant foods did not affect the score of nutrition knowledge On the other hand, the women who had fast foods more frequently got a higher score in food habits and lower score in nutrition knowledge. When college women have a little of nutrition knowledge, they have a tendency to keep their meal time regularity and right dietary attitude pattern. In the dining-out pattern, the college women liked to eat flour foods and they preferred western foods than Korean foods. The motivation of food selection was for convenience and for time saving which were the reason for satisfaction to the products of food service industry. The products of food service industry were found to be unsatisfactory in nutrition and sanitation. Therefore, we must be mute aware of preventing the disappearance of Korean traditional foods and for developing dietary culture successively, the products of food service industry which are more suitable for Korean should be developed.

Purpose: Dietary habits are strongly related to the symptoms of people with irritable bowel syndrome (IBS). Therefore, personalized nutrition management can help reduce symptoms and improve the quality of life of people with IBS. This study assessed the effectiveness of a personalized web-based nutrition management based on the types of food that trigger IBS symptoms. Methods: Sixty Korean adults with IBS according to Rome IV criteria in their 20s and 30s were enrolled in this study. The data from the final 49 patients who completed a three-month personalized nutrition intervention were analyzed. The general information, anthropometry, dietary intake survey, and gut microbiota were examined pre and post-intervention. The gut microbiota analysis included the relative abundance and the Shannon index. The food intake was recorded for two days for personalized nutrition education, followed by three months of personalized nutrition intervention. Statistical analysis was performed using the Wilcoxon signed-rank test in SPSS 26.0, with the significance set to p < 0.05. Results: The relative abundance of the gut microbiota changed after personalized nutrition management, with a significant decrease in the presence of Veillonella (p = 0.048). Furthermore, when the gut microbiota was analyzed according to the type of food that triggers symptoms, the diversity was increased significantly in the high fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) type (p = 0.031) and FODMAPs-containing gluten-type personalized nutrition intervention types (p < 0.001). Conclusions: Gut microbial diversity and gut microbiota distribution changed after using web-based personalized nutrition management. Hence, personalized nutrition management that considers trigger foods may improve IBS symptoms.
