This study was conducted to examine dietary behaviors according to residence status and ethnicity of university students in Yanbian, China. For the subjects, 334 university students (Male=141, Female=193) answered a questionnaire about perception of weight control, dietary patterns, health habits, residence status, and ethnicity. Perception of weight, meal frequency, favorite kind of food, meal finishing time, skipping breakfast, type of breakfast, snack frequency, late-night snack frequency, exercise frequency, regular life, and sleeping time were all significantly associated with residence status. Motivation of weight control, meal frequency, regularity of meal time, meal volume, favorite kind of food, exercise time, and regular life were all significantly associated with ethnicity. University students who lived with their parents perceived their weight more properly, exhibited a more positive dietary pattern, and lived a more regular life than those students who lived in a dormitory with their friends. Chinese students exhibited a more regular dietary pattern and lived a more regular life than the Korean-Chinese students. As a result, both environmental and inherent factors are related with the dietary behaviors of university students in Yanbian, China. These data could be used to help university students in Yanbian, China attain a healthy diet.

The purpose of this study was to analyze the dietary habits and food intake by age, based on the nutrition counseling data of medical health examination. The subjects were 5,511 adults(3,139 males and 2,372 females) who took comprehensive medical test in Gyeonggi area, and they were evaluated from January 1, 2007 to December 31, 2007. Survey samples were divided by age groups : 30>, 30~39, 40~49, 50~59, 60~69, 70{$\leq}$ years. The subjects were composed of 57% male and 43% female. The results showed that the dietary habits of ${\geq}$50 group were relatively good. On the other hand, in 30> yrs group had more dietary habit problems, they had irregular meals and the ratio of skipping breakfast was high. And they frequently had meals out. regularity of meals, eating breakfast was higher in ${\geq}$70 yrs groups than in other groups(p<0.001). frequency of overeating was higher in 30>, 30~39${\geq}$yrs groups than in other groups(p<0.001) and speed of eating meal were fast in 50~59 yrs groups than in other groups(p<0.01). For foods with high cholesterol and fat, it was shown that the older the subject, the fewer the frequency of consumption(p<0.001). For kimchi and salty foods, food intake showed a negative relationship with age(p<0.001), whereas for fresh vegetables and high-calcium fish, it showed a positive relationship(p<0.001). All in all, it was shown that as the people get older, their dietary habits tend to get more appropriate. In conclusion nutrition education based on their dietary habit by age should be taught, so that people have a healthy dietary habit and food intake for the rest of their life.

Purpose: To identify relationships among lifestyle, psychological distress, and reproductive health in female university students. Methods: We used a descriptive cross-sectional design. A total of 275 subjects were enrolled. Subjects agreed to undergo a face-to-face interview, including administration of structured questionnaires to determine health promotion lifestyle profile II (HPLP-II), depression anxiety stress scale for depression and anxiety (DASS-D, DASS-A), and reproductive health (knowledge, attitude, behavior, menstruation irregularity, dysmenorrhea, and gynecologic symptoms). Results: The mean age of subjects was 21.2 years. Those with low HPLP-II score showed significantly high menstruation irregularity. Those with high depression and anxiety had significantly high reproductive symptoms. In addition, high HPLP-II score was correlated with low depression, anxiety, and high reproductive health. Conclusion: The life style of female university students is associated with depression, anxiety, and reproductive health. To improve female university students' reproductive health, life style interventions including healthy nutritional habit, physical activity, and stress management are important.

The purpose of this study was to provide basic information for developing nutrition education programs for preschool children and their families. The subjects were 291 parents whose children went to daycare centers in Uiwang. The questionnaire contained 15 items for children's dietary habits and six items for parents' nutritional attitudes. The results of frequency analysis of children's dietary habits were as follows: 63.9% of children ate meals regularly, however breakfast (46.4%) was usually skipped; 44.0% of children ate a snack more than twice per day; 56.7% did not have late night meals; 49.5% ate out once to twice per week; 89.7% had dinner with family more than three times per week; and 43.6% had picky eating habits. The percentage of children who did not eat vegetables and seaweed was the highest among other food groups. Intake frequencies were low in fatty foods, instant foods, and fast foods. Some correlations were observed between picky eating habits and other dietary habits by cross-tabulation analysis. Intake frequency of non-picky eating children was lower for late night eating and fatty foods but higher for vegetables and seaweed compared to picky eating children. Parents answered that their nutritional knowledge level was normal (72.2%), and nutritional information was collected using the Internet (36.0%). Nutritional value was the most considered point in meal preparation of parents (43.3%), and the most difficult factor in child's diet management was lack of time due to working (36.1%). Parents cited method of creating a menu (27.0%) and table manners (25.3%) as topics of nutrition education by professionals. Therefore, various nutrition education programs need to be developed to improve healthy dietary habits for children and their families.

This study investigated recognition of food labeling of high school students (males 94 and females 85) in Yongin region. Recognition of food labeling was very high at 81.6%. For checking food labeling at the time of purchasing, 53.6% of the respondents always checked and the main reason was healthier food choice (49.2%). Satisfaction of food labeling was very low at 18.4%. In spite of very low satisfaction, 70.9% of respondents recognized necessity for education of food labeling. In terms of education method, respondents preferred 'school lecture' the most with 48.6%, which are in the following order: TV/newspaper/journal/book (37.4%) > internet lecture (10.1%) > education from parents (3.9%). Moreover, 83.2% of respondents answered 'positive change (ex. checking food labeling)' after getting education. Consequently, high school students had low level of utilization of food labeling at the time of purchasing. However, they showed high level of perception and educational need of food labeling as well as possibility of positive change after receiving education. Therefore, appropriate school education for food labeling may be able to lead a healthy eating habit of high school students.

Fragaria ${\times}$ ananassa (Duch.) cultivars, 'Wongyo 3 115' a nd 'Wongyo 3 116', we re bre d as a n inte rme diate parent l ine using heterosis of $F_1$ hybrids in octoploid strawberry. These two new cultivars were developed as inbred lines ($S_9$ generation) propagated from both seed and runners/stolons. 'Wongyo 3115', an inbred line derived from the 'Benihoppe' cultivar, has a semi-upright plant shape showing a vigorless growth habit, weaker than the original 'Benihoppe' cultivar; it has early flower bud differentiation and produces 10 flowers per cluster when grown from healthy seed. 'Wongyo 3115' has low yields of conical type fruit with pink colored skin; average fruit weight is approximately 11 g. The important characteristic of 'Wongyo 3115' is its excellent fruit firmness, firmer than the original variety. 'Wongyo 3116', an inbred line derived from the 'Doyonoka' cultivar, has an upright plant shape, vigorless growth habit, weaker than that of the original 'Doyonoka' cultivar; it has early flower bud differentiation and produces 8 flowers per cluster when grown from healthy seed. 'Wongyo 3 116' has oblate type fruits with red skin and an ave rage weight of approximately 12 g. The important characteristics of 'Wongyo 3116' are excellent fruit shape and higher yield than other inbred lines, although it produces small fruits compared to the original cultivar. Both cultivars have excellent taste, high sugar/acid ratio, and good texture. In regards to disease and pest resistance, 'Wongyo 3115' and 'Wongyo 3116' have a tendency to be sensitive to powdery mildew, anthracnose and the two-spotted spider mite.

The purpose of this study was to compare and analyze life habits and senior fitness according to metabolic syndrome by sex and age in the elderly and prevent metabolic syndrome in the elderly. A questionnaire survey for life habits and senior fitness measurement were conducted with 159 old men and 233 old women(a total of 392) who used welfare facilities for the elderly located in G Metropolitan City. The results were as follows. 1. In the comparison of life habits according to metabolic syndrome by sex and age, while old men showed a significant difference in smoking, drinking and drug intake, and stress relief, old women showed a significant difference in drinking and drug intake and dietary habits. 2. In the comparison of senior fitness according to metabolic syndrome by sex and age, while old men had a significant difference in lower and upper body muscle strength, old women had a significant difference in lower and upper body muscle strength, and general endurance. Based on the findings, the elderly's life habits according to metabolic syndrome had a difference in smoking, drinking and drug, and dietary life and senior fitness had a significant difference in muscle strength, flexibility, and endurance. Thus, the elderly need the methods for exercise habits and stress relief for healthy life. Also, old men should steadily strive to improve flexibility, endurance, agility, and balance and old women should steadily strive to improve agility and balance. When the elderly are careful for decreased fitness with age and strive to maintain healthy life habits, their quality of life will be improved and metabolic syndrome will be prevented.

The risks of the metabolic syndrome (MS) is known to be related to the dietary behavior. The objective of this study is to evaluate the association between the relative risks of MS and the dietary habit and to provide the ideal dietary habits for prevention of chronic disease of the middle-aged. Healthy subjects aged 40-64 years (male n=122, female n=173) were recruited throughout Seoul area. MS was defined according to NCEP-ATP III criteria except central obesity, and Asia-Pacific Area criteria for central obesity (2000) was adapted. Subjects were stratified into 3 groups according to the number of total risk factors:'MS group' was defined as the subjects who have three or more risk factors, 'Risk group' was defined as ones to have one or two risk factors, and 'Healthy group' defined as ones with no risk factor. In this study, 'Health group' comprised of $40.7\%$, the percentage of 'Risk group' was $49.0\%$, and the 'MS group' was $9.5\%$ of the total subjects. The MS incidence was associated with low education (p<0.001), low economic status (p<0.05), and low self-assessed health recognition (p<0.05). The risk of MS increased with adverse life styles such as cigarette smoking (p<0.05), irregular meal time (p<0.05), skipping lunch (p<0.05), low interests in balanced diet (p<0.05), and higher salt intake (p<0.01). Healthy group self-evaluated nutritional knowledge more highly (p<0.05) and scored higher nutritional knowledge (p<0.001). However, there was no difference in overall nutritional behavior among the three groups, which implies that nutritional education method should be developed for the subjects to practice their teaming efficiently.

This study examined the effectiveness of two commonly used dietary assessment methods (the 24-hour recall and the food frequency questionnaire) in the epidemiological investigations of health-related habits and degenerative diseases. This cross sectional project in the Seoul area was conducted for the purpose of establishing cohort subjects and collecting reliable nutrient intake data for a further large-scale cross sectional study. The subjects were 91 volunteers from the Seoul area with a mean age of 53.5 \pm 9.6 for the males and 52.2 \pm 8.9 for the females. The subjects had a relatively high educational background, were from high socioeconomic levels, and were greatly concerned about healthrelated life styles. There was a significantly negative correlation between their smoking and their nutrient intake. Their drinking habits, their self-estimated health status and their concern or stress about being healthy did not have any influence on their nutrient intakes. Skipping meals was the most undesirable dietary habit influencing their nutrient intakes, and the next was their irregularity of eating meals. The subjects who liked legumes and fish had higher intakes of iron and niacin and those who liked milk and dairy products had higher intakes of calcium, vitamin \B_2 and fat. The subjects who considered themselves not to be healthy consumed higher amounts of fish and shell-fish, and those who considered themselves to be healthy consumed higher amounts of vegetables. The smokers consumed less fruits than non-smokers, but there was no correlation between their drinking and consumption of the food groups. There was no correlation between their food consumption frequency and their skipping meals or meal irregularity. There were positive correlations between their food likes and food consumption frequency for foods such as meat, milk and dairy products, seaweeds and fruits. Therefore, their smoking, skipping meals and meal irregularity appeared to greatly influence their nutrient intakes. Significant correlations were found between their health-related habits and their food group preferences and food frequencies. This implies that simple surveying methods using criteria such as smoking, skipping meals and meal irregularity, food group preferences and eating frequencies can be used as useful tools in the assessment of nutritional statuses.
