The purpose of the present study is to investigate the correlations between food intake behavior and job stress level and neuropeptide hormone concentrations. Job strain and food intake behavior were first identified using a self-reported questionnaire, concentrations of neuropeptide hormones (adiponectin, brain derived neurotrophic factor [BDNF], leptin, and ghrelin) were determined, and the correlations were analyzed. In the results, job strain showed significant correlations with adiponectin (odds ratio [OR], 1.220; 95% confidence interval [CI], 1.001~1.498; p < 0.05) and BDNF (OR, 0.793; 95% CI, 0.646~0.974; p < 0.05), and ghrelin exhibited a significant correlation with food intake score (OR, 0.911; 95% CI, 0.842~0.985, p < 0.05). These results suggest that job stress affects food intake regulation by altering the physiological concentrations of neuropeptide hormones as well as emotional status.

This study was conducted to evaluate the nutritional status of the elderly women, who attended the Health Promotion Program of the Seogu Health Center in Daegu. The study subjects were 158 elderly women in an urban community. The general characteristics, dietary behavior (nutritional knowledge, nutritional attitudes and dietary habits), food and nutrient intake were surveyed by an individual interview. The average age of the study subjects was 70.9 $\pm$ 2.3 years of the subject group 79.1% ranged in age from 65 to 74 years and 20.9% were over 75 years. Their average score for nutritional knowledge, nutritional attitudes and dietary habits was 7.3 (total mark of 10), 7.2 (total mark of 10) and 9.1 (total mark of 22) respectively. Specifically, the level of the dietary habits of the study subjects was very low. In relation to food group intake of the study subjects according to age, their food intake was low. The total, plant. and animal food intake were 1078.9 g, 954.4 g (88.5%), and 244.4 g (11.5%), respectively. The mean daily energy intake and nutrient intake according to percentage of the Korean RDA were higher in the from 65 to 74 year group than in those people over 75 years. The average calories and the mean percentage of nutrient intake, except for vitamin C and phosphorus. were below 75% of the Korean RDA. It seems that the nutrient intake was very low. The mean nutrient adequacy ratio (MAR) was 0.59. Nutritional status of age over 75 years old was significantly lower than that of 6574 years old group (Mar ＝ 0.60 VS 0.54, p ＜ 0.05) The correlation coefficients between their dietary behavior (nutritional knowledge, nutritional attitudes, dietary habit) and their mean nutrient adequacy ratio (MAR) showed significant linear relations. In conclusion, if nutritional education is to affect the dietary behavior of elderly women, it should be included in a Program to Promote their nutrition and health status.

The purpose of this study was to investigate perception and awareness of yaksun and willingness to eat yaksun in the future, and to examine the factors affecting intake behavior of yaksun of adults in Daegu and Gyeongbuk region. The data were collected in April, 2011 through a self-administered questionnaire. Chi-square test, t test, and binary logistic regression were conducted by SPSS Windows V.19.0. The results were as follows. Almost sixty-six percent of the respondents answered that they knew yaksun. The perception level of yaksun for the intake respondents was higher than that of non-intake respondents. Additionally, many respondents agreed to varied menu development and convenient-food development of yaksun. Intake respondents showed higher level of agreement for the varied menu development of yaksun than non-intake respondents. On the other hand, four fifths of the respondents showed that they would be willing to eat yaksun in the future. The level of willingness to eat yaksun in the future for the intake respondents was higher than that of non-intake respondents. Additionally, the respondents who knew yaksun showed higher level of willingness to eat it than those who did not know it. Finally, the result of binary logistic regression analysis for intake behavior of yaksun showed that gender, educational level, and the awareness of yaksun were significant. On the basis of these results, not only the promotion of yaksun to consumers but also the development of convenient foods, varied menus for different age groups, and menus with cheap prices are needed to raise yaksun popularity.

This survey was carried out to study the difference of nutrient intake, food behavior and health condition according to food intake diversity in the elderly(age 65 year over and 74 year under) in a local city. A diet survey with one day 24-recall method was used for 216 subjects(65 male & 151 female). Based on a food intake diversity examination, including an evaluation of KDDS(Korean's Dietary Diversity Score ; counts the number of food groups consumed daily from total five food groups(cereal, meat, vegetable, dairy, and oil groups)), Meal Balance(apply the KDDS at breakfast, lunch and dinner), and DVS(Dietary Variety Score ; total number of foods consumed), subjects were clustered according to food intake diversity. Food intake diversity patterns of male and female clusters were classified each into threes(Male-low group(24.6%), middle group(33.8%), and high group(41.5%)/Female low group(41.7%) middle group(37.1%), and high group(21.2%). The averages of KDDS, Meal Balance and DVS were 3.0, 7.5, 14.8 in the male middle group, and 4.5, 10.2, 25.7 in the male high group, 2.7, 6.3, 14.3 in the female low group, 4.0, 8.6, 18.0 in the female middle group, and 4.5, 10.5, 25.7 in the female high group respectively. The average dairy intake of nutrients below the RDA were energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$and niacin in the male low group, energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$in the male middle group and energy, Ca, Vitamin B$_2$in the male high group but a little. Also the female low group had intakes of all nutrients except Vitamin C, the middle group had intakes of energy, protein, Ca, Fe, Vitamin A, Vitamin B$_2$, and the female high group had intakes of energy, Ca, Vitamin A below the RDA respectively. Food intake diversity increasing, nutrient intake, food behavior and health condition proved to be good. This study explored the usefulness of cluster analysis in identifying food intake diversity of three groups of the elderly in relation to their nutrient intake, food behavior and health conditions.

Four Holstein heifers were used in the present study to investigate the effect of standing and lying behaviors on heat production and physiological responses under low (L), medium (M) and high (H) levels of TDN intake. Rectal temperature (RT), respiration rate (RR), heart rate (HR), heat production (HP) and animals behavior (standing time, ST) were measured continuously for 5h (11:00-16:00) periods. There was a tendency for increased RT with TDN intake, and no difference in RT was observed between standing and lying. The RR, HR and HP during standing were significantly higher (p<0.05) than during lying. The difference between standing and lying HP were 4.41, 4.68 and $5.37kJ/kg^{0.75}$ h for L, M and H of TDN intake, respectively. These values showed that standing HP was 18.6-20.9% higher than lying HP. A multiple regression analysis of HP ($kJ/kg^{0.75}$ h) on TDN intake ($g/kg^{0.75}$ d) and ST (min/h) was HP = 7.75 + 0.28 TDN intake + 0.12 ST (R = 0.84). This analysis showed that the total HP not only depend on feed intake levels, but also depends on animal behavior. It was suggested that the change in HP due to the change in feed intake and animal behavior would influence the level of heat loss which was indicated by the changes in the RR and HR.

Objectives: The present study was conducted to investigate associations between eating style and food intake of 45 female college students during Chuseok holidays. Methods: A ten-day food record was obtained and divided into two parts. The first five days (September 20-24, 2015) were considered as a 'Normal Day (ND 1-5)' and the subsequent five days (September 25-29) as 'Holiday (HD6-10)'. The middle three days (September 26-28) of the holidays were considered as the 'Peak Holiday (PD7- 9)'. Eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ) and anthropometry was assessed in all study participants. Participants were grouped by cluster analysis according to the mean energy intake of the first three days of the Holiday. Results: Participants had a low-normal range of BMI and they were carefully restricting their food intake at Normal Day. Even the food intake did not exceed 2000 kcal per day during the Peak Holiday. External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Normal energy and fat intake were correlated with the external eating subscale of the DEBQ. Restrained eating was associated with the weight, BMI, fat mass, waist, and hip girth of the subjects. Compared to the Normal Day, they overate during the Holiday with different eating styles including 'restraint', 'disinhibition', and 'fluctuation'. Therefore, neither eating behaviors nor anthropometry was associated with food intake during the Holiday. Although eating behaviors and anthropometric measures were not different among eating style clusters, the food intakes of disinhibition cluster were higher than those of restraint cluster during all the study periods. Conclusions: Subjects can be classified with the restraint, disinhibition, and fluctuation clusters. However, eating behaviors and anthropometry were not different among three clusters.

The purpose of this study was to identify the effectiveness of a nutrition education program of reducing children's sugar intake based on social cognitive theory. This education program composed of 6 units was conducted in discretional activity class of the $3^{rd}$ and $4^{th}$ grade elementary school students. The results are as follows: First, the rate of correct answers and score of nutrition knowledge significantly increased after nutrition education. The scores of nutrition education in male students, students whose mothers have no job, and students with skinny physiques were much improved after nutrition education(p<0.05, p<0.01, p<0.001, respectively). Second, the dietary attitudes toward reducing sugar intake and checking nutrition labels significantly improved(p<0.05). And also, it tended to decrease in preference and intake of sweet foods. Third, the consumption of candy caramel jelly(p<0.05), yogurt(p<0.05), jam honey(p<0.05), and ice cream(p<0.001) were reduced after nutrition education. Besides, obese students' consumption of isotonic beverages, carbonated beverages, and fruit juice was reduced. Therefore, a positive change in dietary behavior appeared. Based on the above results, we confirmed that the nutrition education program focusing on reducing sugar intake applied with social cognitive theory was effective for improving the nutrition knowledge, dietary attitude and dietary behavior in sugar intake in elementary school students. Especially, this program showed the improvement in nutrition knowledge as well as dietary attitude and behavior in sugar intake among obese children. Since nutrition education during childhood significantly influences lifetime-health and disease prevention, it is necessary to develop theory-based nutrition education program and practice systematic and constant nutrition education in elementary schools.
