The purpose of this study was to investigate middle school students' perception of environment-friendly agricultural products (EAPs) and the degree of confidence about the certification mark. Questionnaires were distributed to 444 students of 6 middle schools located in Daegu, and a total of 416 responses were used for analysis. 28.6% of the respondents were using EAPs at home, and 62.0% of respondents didn't know whether to use EAPs at home. The 6 items representing the perception of EAPs were analyzed, resulting in 2 distinct dimensions-'benefits of EAPs' and 'attitude toward EAPs'. Regarding Benefits of EAPs, the score of 'EAPs better for health' was the highest, followed by 'EAPs have higher quality', 'EAPs were better for environmental protection', respectively. The proportion of students responded that 'the amount of pesticides should be reduced gradually' was 65.5% and only 3.4% for 'current level of pesticide use is not a problem'. There were significant differences between male and female students with regard to an interest in EAPs (p < 0.05) and opinion on the use of pesticides (p < 0.05), while no significant difference was found between groups with different education level of mothers. The respondents who use EAPs at home showed significantly higher scores with attitude toward EAPs (p < 0.001), and higher response rate for 'pesticides should not be used even if the price increases' (p < 0.05). Degree of confidence about the EAPs certification mark also affected students' perception of EAPs (p < 0.001). Our results indicate the importance of education for students on EAPs to enhance students' attitude towards EAPs and improve school meal satisfaction.

BACKGROUND/OBJECTIVES: While the use of food additives in food processing has become a common practice worldwide, consumers' worry about potential hazards has not diminished. The purpose of this study was to identify trends in South Korean parents' perceptions about food additives by analyzing the results of surveys conducted from 2014 to 2018. SUBJECTS/METHODS: We conducted an off-line survey in Korea annually between 2014 and 2018 on perceptions about food additives. The numbers of survey respondents in each year from 2014 to 2018 were 381, 426, 301, 519, and 369, respectively. Our consumer respondents were parents of elementary-school-aged children. RESULTS: The ratios of respondents perceiving "food safety" as the most important factor in purchasing processed foods and "food additives" as the biggest threat to food safety have decreased over the years. However, most consumers still have negative perceptions of food additives. Additionally, among consumers lower confidence in or trust of the Korean government continued throughout the study period and appeared to be the main problem that needs to be overcome. CONCLUSIONS: This study found that Korean parents are still troubled by food additives. Consumers' confidence in the government needs to be increased through public communications. More multifaceted educational programs communicating scientific knowledge of food additives are needed in order to correct consumers' misperceptions.

As a way to account for the variability of the primary model parameters in the secondary modeling of microbial growth, three different regression approaches were compared in determining the confidence interval of the temperature-dependent primary model parameters and the estimated microbial growth during storage: bootstrapped regression with all the individual primary model parameter values; bootstrapped regression with average values at each temperature; and simple regression with regression lines of 2.5% and 97.5% percentile values. Temperature dependences of converted parameters (log $q_o$, ${\mu}_{max}^{1/2}$, log $N_{max}$) of hypothetical initial physiological state, maximum specific growth rate, and maximum cell density in Baranyi's model were subjected to the regression by quadratic, linear, and linear function, respectively. With an advantage of extracting the primary model parameters instantaneously at any temperature by using mathematical functions, regression lines of 2.5% and 97.5% percentile values were capable of accounting for variation in experimental data of microbial growth under constant and fluctuating temperature conditions.

Consumer's concerns over beef safety are increasing according to resuming U.S. beef import. And a few beef producers have converted into organic beef recently. This organic beef must have taste, nutrition and safety that consumers demand for. Korean organic beef should be gone on sale at the shop under direct management of producer's organizations or the special shop for Environmentally friendly products. So they should win consumers' confidence for beef safety and transparency in producing and marketing process.

The aims of this study were to evaluate obesity-related dietary behaviors and to determine long-term exercise effects on obesity and blood lipid profiles in elderly Korean subjects. A total of 120 subjects, aged 60-75 yr, were recruited, and obesity-related dietary behaviors were determined. An exercise intervention was conducted with 35 qualified elderly females for 6 months, and body composition and blood lipids were measured 6 times at 4 week intervals. At baseline, mean BMI ($kg/m^2$) was 24.8 for males and 23.1 for females. The females had better eating habits than the males and were more concerned with reading nutrition labels on food products (P < 0.001); they also preferred convenience foods less than the male subjects (P < 0.05). Obese individuals were more likely than overweight or normal weight individuals to misperceive their weight (P < 0.001). Those with a high BMI responded feeling more depressed (P < 0.01), lacking self-confidence (P < 0.01), and feeling isolated (P < 0.01) as well as having more difficulty doing outdoor activities (P < 0.01). After exercise, body fat (%) and WHR were significantly reduced (P < 0.05), while body weight and BMI were also decreased without statistical significance. Total cholesterol and blood HDL were significantly improved (207.1 mg/dl vs. 182.6 mg/dl, HDL: 45.6 mg/dl vs. 50.6 mg/dl, P < 0.05). Other benefits obtained from exercise were improvements in self-confidence (26.4%), movement (22.6%), stress-relief (18.9%), and depression (13.2%). In conclusion, elderly females had better eating habits and were more concerned with nutrition information and healthy diets compared to elderly males. However, misperceptions of weight and obesity-related stress tended to be very high in females who were overweight and obese, which can be a barrier to maintain normal weight. Long-term Danhak practice, a traditional Korean exercise, was effective at reducing body fat (%) and abdominal obesity, and improved lipid profiles, self-confidence, and stress.

A sruvey was conducted to investigate the consumer perception of farm products and processed foods, and to figure out the future direction of food supply system to satisfy the consumer need. From the citizens in Taegu area, 532 housewives were selected as sample subjects by stratified random sam-pling procedure. The main criteria of consumers for purchasing farm products was quality and the main reason for purchasing imported products was cheap price(48.9%). Most of consumers(87%) thought that food safety of farm products was not belong to safe level. Consumers(79.7%) perceived that the labeling system for the place of origin and for the quality are necessary, but they did not have confidence in the current label. Nearly all the subjects(93.6%) were concerned about the hazardness of residual chemicals of imported products, desired the rigorous inspection system for imported products. Consumers in Taegu area had confidence in processed foods in the following order; farmerbrand-product(0.9%), government-authorized farm product(30.0%) and agricultural cooperative association product(26.4%). However, only 73.6% of the consumers had the experience to purchase farmers' processed foods. As a conclusion, it appeared that nutrition education for consumers on food-decision making is strongly required for the substantial segment of population who are still ignorant of safety of imported product and food distribution system.

Purpose : This study surveyed the relationship between the dietetic behaviors of high school students and nutrition information available from mass media thereby suggesting the way of improving the dietetic health promotion of adolescents. Method : This study surveyed coeducational high school students in S region. 220 questionnaires have been collected and analyzed, which is statistically significant as in other previous studies. The survey lasted for one month, March 14 through April 14 in 2016. The statistical analysis was performed by using the windows version 21.0 of SPSS. Primarily, the frequency analysis and descriptive statistics was carried out on the general information, the usage and confidence of mass media, and the diabetic behaviors of respondents. t-Test and One-way ANOVA were adopted to clarity the mass media usage and diabetic behaviors of respondents for general characteristics. Result : The statistical analysis on the diet usage of mass media among high school students shows that famous restaurants(Response rate 51%) and diet control(20%) are highly evaluated, but disease prevention(15%) is low. Regarding the dietetic information acquisition, the mass media including TV, radio, and Internet appear as main information carriages (p<.001). The confidence in mass media are analyzed in the relation with 10 dietetic behaviors, and 4 items(meal amount: p<.011, vegetable intake: p<.005, protein intake: p<.003) are inversely related to the mass media, which means regular intake party is less dependent of the exterior information. The seaweed(p<.017) intake is statistically significant in confidence level. Conclusion : To increase the interest and the health promotion of students, the dietetic information need to be offered in mass media and education course.

Purpose: This study was conducted to evaluate the effectiveness of a mother/infant-toddler health program developed to enhance parenting knowledge, behavior and confidence in low income mothers and home environment. Methods: A one-group pretest-posttest quasi-experimental design was used. Sixty-nine dyads of mothers and infant-toddlers (aged 0-36 months) were provided with weekly intervention for seven session. Each session consisted of three parts; first, educating to increase integrated knowledge related to the development of the infant/toddler including nutrition, first aid and home environment; second, counseling to share parenting experience among the mothers and to increase their nurturing confidence; third, playing with the infant/toddler to facilitate attachment-based parenting behavior for the mothers. Results: Following the programs, there were significant increases in parenting knowledge on nutrition and first aid. A significant improvement was found in attachment-based parenting behavior, but not in home safety practice. Nurturing confidence was not significantly increased. The program led to more positive home environment for infant/toddler's health and development. Conclusion: The findings provide evidence for mother-infant/toddler health program to improve parenting knowledge, attachment-based parenting behavior and better home environment in low income mothers. Study of the long term effectiveness of this program is recommended for future research.

The purpose of this study was to determine the attributes and factors of brand personality for contract foodservice management companies. Self-administered questionnaires were distributed to five students at universities operating under the top five companies in contract foodservice management. The following statistical analyses were conducted for the data assessment: descriptive analysis, t-test, ANOVA, reliability analysis, and factor analysis, using the SPSS Win(12.0) package program. From these analyses we divided a company's brand personality into the following five functional and emotional elements: sensibility, sincerity, confidence, competence, and excitement. Based on these five elements a total of 26 scales were developed to measure brand attributes of the companies. The variance was explained by 19.29% of sensibility, 17.65% of sincerity, 15.71% of confidence, 14.06% of competence, and 13.62% of excitement. The calculated Cronbach's alpha was more than .90 for all the scales measuring the five attributes, indicating good internal consistency. There were significant differences in sensibility(p<.01), sincerity(p<.001), creditability(p<.01), competence (p<.001), and excitement(p<.001) among the companies. In regards to overall brand personality, company a had a higher mean score for sincerity, while the other companies had higher mean scores for competence. Among the brand personalities, 'confidence' had the highest mean score with 3.36, followed by 'cooperation' (3.17), 'successful'(3.12), 'leadership'(3.11), and 'down-to-earth'(3.02).
