This study was conducted to determine factors affecting detection threshold and the optimally-preferred concentration for sweet taste, since investigation into factors decreasing sensitivity or increasing preference for sweet taste is important to prevent overconsumption of simple sugar. Subjects were 70 first-grade middle school students in the Gyeonggi-Do. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly were determined by sensory evaluation. A self-administered questionnaire was used to obtain the information regarding health-related lifestyle practices, dietary habits, preference for and eating frequency of Westernized foods and frequencies of eating foods other than home-made. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly of the subjects were 0.204% and 14.44%, respectively. Subjects who exercise less (< 30 minutes/week except PE class), skipping meals (${\geq}$ 3/week), type of breakfast rather than traditional Korean meal and frequent eating out and buying foods from school tuck-shop tended to have higher sweet taste threshold. There was significant positive correlation between the sucrose threshold concentration and fried chicken preference or eating frequency of hamburger. Those who exercise less (< 30 minutes/week except PE class) did have significantly higher optimally-preferred sweetness of omija jelly, which tended to be higher in the subjects who had more (${\geq}$ 4 out of 10) behavioral or psychological stress symptoms and who had early getting-up time (before 7 am). There was significant positive correlations between the optimally-preferred sweetness of omija jelly and pizza preference, instant noodle eating frequency or sum of eating frequencies of five fast foods. From the results of this study, it was suggested that middle school students should make efforts to stop skipping meals, exercise more, eat Korean traditional breakfast and reduce the frequencies of eating out and using instant/fast foods in order to prevent overconsumption simple sugar.

An experiment was carried out to investigate the effect of change in length of hay offered on eating and rumination behaviour in sheep using three types of hay diets (L: long, M: 8.0-cm cut, S: 1.2-cm cut) and 3 Japanese Corriedale wethers, and the experiment was designed as $3{\times}3$ latine square. The time spent eating per 100 g hay was significantly shorter with long (L) hay (p < 0.05) than with chopped (M and S) hay, and therefore, the eating rate (g D.M./min.) was significantly higher in the former (p < 0.05) than in the latter. Rumination appearance (the lag time after eating) tended to be longer with long hay than with chopped hay, but not significantly (p > 0.05). Daily time spent ruminating, the actual chewing time and daily number of chews tended to be more in feeding long hay than in feeding chopped hay, but not significantly. Daily number of rumination periods was significantly more with long hay (p < 0.01) than with chopped hay. Cyclic rate tended to be longer with long hay than with chopped hay, in particular, the difference in values between long hay and 8.0-cm cut hay was significant statistically (p < 0.01). The rumination index (time spent ruminating/100 g D.M, eaten) tended to be higher with long hay than with chopped hay, and the difference in values between long hay and 1.2-cm cut hay was significant statistically (p < 0.05). Bolus time was significantly longer with long hay (p < 0.01) than that with 8.0-cm cut hay. The circadian pattern of ruminating time was not changed by the changes in length of hay eaten.

This study was performed with 482 subjects(278 boys and 204 girls in Seoul and Kyunggido area) to find out the attitude and eating behaviors about Kimchi on Korean young generation. General characteristics about subject and attitude and eating behavior were surveyed by self-developed questionnaires. 85.9% of the subjects were nuclear family type and 49.9% of respondent's mother had full-time job and 96.1% of subjects were middle or upper economic status. The preference for Kimchi, 60.4% of respondents answered that they liked Kimchi. According to grade, the rate of preference about Kimchi was significantly different, higher grade students were found higher preference on Kimchi : 64.4% of middle and 70.4% of high school students liked Kimchi. The eating patterns of Kimchi, up to 60% of respondents answered they ate Kimchi in every meal time, which suggested that it was still an important side dish in Korean meal among teenagers. The eating behaviors on Kimchi, $85{\sim}90%$ of respondents answered that they preferred Kimchi in meal time. Baechu Kimchi(chinese cabbage Kimchi) and Gakdugi(radish cube Kimchi) was highly preferred. And their preference of food which made from Kimchi (such as Kimchi fried rice, Kimchi stew, Kimchi pancake) was highly evaluated. 65.6% of residents pointed out that 'Kimchi is very nutritious food'. The respondent's structure of value on Kimchi were not significantly difference between sex and age. But it was significantly difference(p<0.01) between the groups with preference and familiarity on Kimchi. The group had higher preference and familiarity on Kimchi agreed to the positive values about Kimchi. These result suggested that various kinds of Kimchi should be developed for young generation to meet their taste and also continuous nutrition education about traditional food especially Kimchi should be promoted at home and school.

This study was conducted to investigate whether there were differences in eco-friendly food, home meal replacement (HMR) purchases, and eating-out behavior according to the level of agri-food consumer competence. The data for the study were extracted from main food consumers (n=3,321) in the 2022 Food Consumption Behavior Survey. The competence index was divided into awareness-attitude-practice items, and three groups were classified by competence level. The results showed an agri-food consumer competency score of 70.62, with the highest score for awareness (73.96), followed by practice (69.28) and attitude (66.18). The frequency of purchasing eco-friendly food was higher in the excellent group compared to other groups, and quality and price satisfaction was higher with higher competency (p<0.001). Regarding HMR, the results showed that the shortage group had the lowest HMR consumption rate, and satisfaction decreased as competence decreased (p<0.001). The main reason for eating-out was to enjoy food in all groups (59.0%), followed by a lack of cooking time in the excellent group (15.7%) and hassle with food preparation in the moderate and shortage groups (17.3%, 16.6%) (p<0.001). In short, agri-food consumption competency showed differences by contents and components, and differences in food purchases and eating-out behavior by competency level were found.

An experiment was carried out to study the effect of environmental color on the eating behaviour in broiler chicks. A total of ninety broilers with average 350g of initial body weight were randomly assigned in the $3{\times}3$ randomized complete block design with 3 treatments(yellow, blue, red) and 10 birds per replication of various environmental color at walls, feeders and electric bulbs. The results obtained from these experiments are summarised as follows: 1. Feed Intake and average daily gain were significantly(P<0.05) increased by yellow colored environment. 2. Eating time and eating rate were significantly higher in the red colored than the other, indicating that yellow colored environment would maximize body weight gain and feed conversion for broiler chicks.

Effective parenting attitudes have been known to be associated with children's health practices including dietary intake and physical activity. The objective of this study is to compare children's body weights and eating habits by maternal parenting attitudes. Data were collected at school (N = 396; 4th and 5th grade students) using self-administered questionnaires on maternal parenting attitudes, eating habits and physical activity. Parenting attitudes were categorized as 1 of 4 parenting attitudes (overprotective, authoritarian, democratic, and neglectful) using affection and control median cut points. Children's body weights, frequency of breakfast, eating out and fastfood, and physical activity were compared by maternal parenting attitudes. Children's body weights were related with mother's employment status (p < 0.05) and parenting attitudes (p < 0.01). Children of unemployed mothers were more likely to be overweight. Children of neglectful mothers (p < 0.01) were more likely to be underweight, compared with children of mothers with other parenting attitudes. Since, unfortunately, the number of children of neglectful mothers was very limited in this study, we could hardly assess eating habits of children of neglectful mothers. Children of authoritarian mothers ate breakfast more regularly (p < 0.05), but ate snacks less regularly (p < 0.01). Children of democratic mothers ate fastfood less frequently (p < 0.01) and ate snacks more regularly (p < 0.01). Meanwhile, children of overprotective mothers ate breakfast less regularly (p < 0.05) and ate out less frequently (p < 0.01). However, maternal parenting attitudes were not related to children's physical activities. In conclusion, the maternal democratic parenting attitude was associated with healthy eating habits including regular snack time and less fastfood. On the other hand, the maternal neglectful parenting attitude was associated with high risk of children's underweight. Understanding the mechanism through which parenting attitude is related with underweight risk and healthy eating habits may lead to the development of better interventions.

The purposes of this study were to determine what kinds of food university students had, how often they were eating out and how much they consumed. A questionnaire survey was conducted on 597 university students (male $40.9\%$, female : $51.9\%$). The students who spent under 200 thousand won per month had regular meals at breakfast, lunch and dinner. The students with personal monthly spending over 300 thousand won, both male and female, ate out more than others. The female students had more protein foods than the male students. Consumption of milk and milk products increased with rising monthly spending for female students. Regardless of monthly spending, the male students ate seaweeds low in 1-2 time per a week. Consumption of rice decreased with rising monthly spending for male and female students.

Objectives This study was performed to figure out relations of self-esteem, anxiety and the other factors related with obesity in obese children. Methods Forty-two children(21 boys and 21 girls) those who were diagnosed obesity have been recruited. To assess psychological factors, Self-esteem inventory(SEI), Revised Children's Manifest Anxiety Scale(RCMAS), International Physical Activity Questionnaires(IPAQ), Korean Eating Attitudes Test(KEAT-26) and Children's Depression Inventory(CDI) were administered. Behavioral characteristics were also analyzed. Results Self-esteem(SEI) had significant positive relationship with physical activity(IPAQ) and sleeping time. Self-esteem had significant negative relationship with anxiety(RCMAS), eating disorder(KEAT-26) and watching TV time. Anxiety had significant positive relationship with eating disorder(KEAT-26) and watching TV time, and negative relationship with physical activity(IPAQ) and sleeping time. All of participants seemed to be having depressive tendency. Conclusion Self-esteem and anxiety were significantly related. And eating disorder, physical activity, sleeping time and watching tv also affected to the self-esteem and anxiety of obese children.

The purpose of this study was to investigate the eating behavior and life habits of kindergarten children 5 to 7 years old in Chuncheon area. This study was conducted in December, 1996. Anthropometric indices(height, weight, skinfold thickness, mid-arm circumference) were measured and body mass index(BMI), Rohrer index, arm fat area were calculated to estimate children’s body fatness. Also the eating behavior and life habits were determined tv using questionnaire method. The results were as follows: Body fat rate of the children was almost normal according to Rohrer index and BMI. There was significant difference in birth weight between male and female. The problems of the eating behavior were frequent skipping breakfast and eating-out. The rate of the children who took snacks 2 times a day was 46.9％. Most children tended to take sweet snacks such as ice-cream, chocolates, cookies, and they tended to prefer meats and fishes to vegetables. The rate of breast feeding was 28.3％ and the rate of weaning foods prepared at home was 61.1%. Many children preferred indoor activities such as watching TV, toy furniture play, building block to outdoor activities such as roller-skating, cycling, jogging in their spare time. The rate of the children who took exercise regularly was 15％. Children tended to eat kimbap, fried chicken, ramyeon more frequently in various instant foods. The intake rates of fruit juice and barly tea were relatively high and children's favorite fruits were watermelon and mandarin orange. From this results, skipping breakfast, frequent eating-out and the monotony of food preference appears to cause imbalance in nutrient intakes of the children and to have bad influence on children’s health. Accodgingiy, the comprehensive nutrition education and proper modification program should be needed for the children and their parents to correct the eating behavior and life habits. The reasonable exercise programs are needed to motivate outdoor activities of the children, and the importance of breast feeding and weaning foods should be emphasized to lactating women and pregnant women.
