Background & objectives: Life style modification reduces the health risks of young people and improves their health status. Physical activity is known the effective factor to reduce health risks and health problems. This study performed to analyze health promotion behaviors related to physical activity among first-year students of university. Methods: To examine the association with physical activity and health promotion practices, health survey was conducted with 3,806 students who were first-year students in a university by self-reported questionnaire from February 26 to March 10, 2015. Multiple logistic regression analysis was performed to identify the difference of health promotion behaviors by physical activities. Results: 51.4% of the first-year student was regular exercisers who had practiced on regular walking exercise or regular strength exercise or regular aerobic exercise for a week. 87.8% of students exercised one or more times within the last one week. On the other hand, 12.2% of them did not exercise. In multiple logistic regression models, it remained significantly the difference of regular exercise by gender, subjective health status, sleeping time per one day, BMI, drinking behavior, and eating habit (p<0.05, p<0.01, p<0.001). Also it remained significantly the difference by physical activity type, such as walking, strengthen, and aerobic exercise (p<0.05, p<0.01, p<0.001). Conclusion: To help the achievement of academic goal, it should build physical activity policies and comprehensive health promotion programs to reduce health risk factors of university students. Comprehensive university health services and customized program for university students could help to make the best of their health. In future, to enhance physical activity practice, it needs to develop various tailed messages and smart healthcare service using health information technology (IT) on campus.

Shakespeare's plays deploy an interesting array of food signs in a way to illuminate the historical process of what Stephen Mennell has described as "the civilizing of appetite"-a process in which the changes of food choices and eating habits took place in response to the changes in people's way of life and personality structure over the long-term modern period since the middle ages. Shakespeare's plays suggest that the civilizing of appetite in early modern England was heavily affected by the forces of social mobility as well as the nascent market economy. The Capulets' costly preparation of Juliet's wedding banquet is a showcase of conspicuous consumption which was a structural necessity for the ruling class in Shakespeare's time. Some fifteen years later, the same kinds of foodstuffs are included in a shepherd's shopping list for the sheepshearing festival in Winter's Tale. This is a significant coincidence to prove that food was an important source of emulation and contest among different social classes; and that the rich diet of the upper class gave impetus to social mobility. The Elizabethan subjects, especially among the elite noblemen, were interpellated by the ideology of food that equated the quality of food and the eater's social identity. Faced with bankruptcy as a consequence of his extravagant consumption habit, Bassanio in The Merchant of Venice testifies to the gripping ideology of food onto early modern people, while Poor Tom in King Lear presents a comic parody of the rich people's conspicuous waste. Also in Coriolanus and The Merry Wives of Winsor, Shakespeare uses food as a metaphor for class-motivated social struggles.

This study was conducted to examine the relation between a mother's LOHAS lifestyle propensity, healthy dietary life, and nutrient intake perceived by Chinese university students. The subjects consisted of 376 Chinese university students. The research results are summarized below. The mother's LOHAS attitude index was 76.02 points out of a perfect score of 100 points. High LOHAS attitude factors of mothers were 'health', whereas 'social welfare' scored low. The highest LOHAS attitude items of mothers that Chinese university students perceived was 'My mother uses health food, organic food, clean food'(4.26 points). Males who lived on their own in a large city and have normal BMI ($18.5{\sim}22.9kg/m^2$) perceived a high mother's LOHAS score. The highest food habit variables are 'eating without spilling food' 'cleaning up after meals around' and 'washing my hands before meals'. The highest healthy dietary life item is 'I try to maintain a pleasant and enjoyable life'(3.83 points). The highest nutrient intake attitude score is 'I tend to eat yellowish-green vegetables every day.'(3.92 points). According to mother's LOHAS lifestyle score, it was verified that the higher mother's LOHAS lifestyle score, the higher children's food habit, healthy dietary life, and nutrient intake score are. Mother's environment-friendly LOHAS attitude index has a meaningful impact on the child's food habits, healthy dietary life, and nutrient intake.

This study was performed to investigate the effects of very low calorie diet (VLCD) using meal replacements that contain the wild grass extracts based on Samul-tang ingredients on psychological factors and quality of life in the obese women $(BMI{\geq}25kg/m^2)$ for four weeks. Seventy five women $(20{\leq}age<26)$ participated in this experiment. Subjects were randomly classified three groups: 1) General diet group (GD roup, n=27) consumed 3 regular meals within 600 kcal/day 2) Meal replacements group (MR group, n=27) consumed 1 regular meal and 2 meal replacements within 600 kcal/day 3) Herbal Meal replacements group (HMR group, n=27) consumed 1 regular meal and 2 meal replacements within 600 kcal/day. Physical factors (weight, BMI, fat (%)) of the HMR group significantly decreased more than those of GD and MR groups. Moreover, binge eating habit and environmental factors (surrounding support, emotional reaction, expression of opinion) of the HMR group significantly decreased more than those of GD and MR groups. Psychological factor and quality of life were no significant differences among three groups during the experimental period, because both were significantly decreased in all groups after 4 weeks. Therefore, very low calorie diet using meal replacements that contain the wild grass extracts based on Samul-tang ingredients for 4 weeks was effective on improvement of psychological factor and quality of life as well as weight reduction in the obese premenopausal women.

This study describes the prevalence of nutrition labelling use and its association with demographic factors, knowledge and perception of nutrition labelling, and awareness of nutrition labelling usefulness among 282 college students, aged 21~23 years, in Busan Gyeongnam area. The subjects consisted of 150 of male (53.2%) and 132 of female (46.8%) students. 31.3% of male students and 50% of female students reported reading nutrition labelling always or usually, while 34.7% of male and 13.6% of female subjects reported that they don't use nutrition labelling. Although most of the subjects perceived the need of nutrition labelling, their knowledge and understanding of nutrition labelling and their awareness of nutrition labelling usefulness were not enough to apply the information from the nutrition labelling in their daily life, even in the subjects who reported reading nutrition labelling always or usually. This statement might be one of the reasons why there were no significant differences among the groups divided by nutrition labelling use in regards to the dietary habit or snack eating habit in this study. Therefore, a practical nutrition education program on nutrition labelling should be provided for the college students to increase nutrition labelling use and to apply the information from nutrition labelling in their daily life in order to maintain healthy dietary habit.

1. As the low standard of living of the people who live in both the model and compared villages, is almose similar to each other, the state of their food intaking has nearly the same degree. 2. The villagers of the two kinds of village mentioned above do not cast off their traditional eating habits getting an energy from rice and vegetarian diet. They, however, have been so much interested in the problem of birth control that they have a few children in less than four-year-old. We have to go on the problems of driving a reasonable family plan, and replacing the traditional food life by taking a fatty food. 3. Their pool life forces them to have an over work for supporting their family. Even though they take much Fe from grains and vegetables day after day, Fe does not give a great influence on making Hb (Erythrocyte) in a body. Accordingly most of them have developed symptoms of anemia. This research, comparing with the research results of Ewha University and Seoul Medical College shows much lack of Hb. So it is need for them to take a large quantity of animal protain and make a healthful habit by reforming their food life.

Objectives：Authors hypothesized that bipolar tendency of non-psychiatric person would be associated with stress vulnerability. To test the hypothesis, we compared perceived stress level, Type A Behavioral Pattern (TABP) and unhealthy lifestyle between person with and without bipolar tendency. Methods：The study cohort consisted of 1987 subjects without past and current psychiatric history. In this study, bipolar tendency was determined by MDQ response which requires endorsement of at least 7 of the 13 "yes or no" questions. We compared the scores of Perceived Stress Scale, A/B lifestyle questionnaire, and unhealthy lifestyle(alcohol, smoking, lack of exercise, irregular meal) between MDQ positive and negative respondents. Results：We identified the bipolar tendency group determined by the MDQ positive response were 329 subjects(16.6%). The overall score of the bipolar tendency group was significantly high on the A/B lifestyle questionnaire compared to the non-bipolar tendency group(125.4 vs. 115.9, p<0.001), and the rate of the subjects defined as TABP was also significantly high(41.3% vs. 30.1%, p<0.001). In comparison of subjectively perceived stress level, the bipolar tendency group was observed to be significantly higher than the non-bipolar tendency group (18.5% vs. 16.5%, p<0.001). The bipolar tendency group was significantly higher than the non-bipolar tendency group on the rate of answering：'irregular eating habit' (20.1% vs. 14.3%, p=0.002), '4-or-more-times alcohol intake per week' (29.8% vs. 16.5%, p<0.001), 'currently smoking' (41.9% vs. 23.0%, p<0.001), '2-or-less-times physical exercises per week' (63.2% vs. 55.1%, p=0.007). Conclusion：By clinical diagnosis, even a person who does not meet the criteria of bipolar disorder has a high risk of stress-related behavioral pattern, and perceived stress when possessing bipolar tendencies such as the (hypo) maniac tendency or affective instability. Such individual has significantly higher risk of having unhealthy life-style such as smoking, drinking, irregular eating habit and lack of exercise compared to non-bipolar tendency group. Since these risk factors lead to increase the risk of obesity, metabolic syndrome, diabetes, and cardiovascular diseases, the individual with the bipolar tendency requires a more effort to manage stress and to maintain healthy lifestyle.

In order to investigate the ecological factors affecting milk intake frequency of adolescents, the questionnaire survey was conducted with 929 middle and high school students living in Chungnam urban area through October and November 2004. The subjects consumed milk 8.6$\pm$6.7 times per week, other beverages 4.4$\pm$4.1 times per week and drinking water 3.7$\pm$2.1 cups per day. Of the students 77.3% took balanced meals, 72.8% ate regularly and 36.2% ate adequate amount. About 61% had breakfast everyday and nearly a half students snacked once a day. Nutritional knowledge scores about milk was 7.2$\pm$1.7 and milk attitude scores was 28.1$\pm$6.5. The subjects spent daily 1.8$\pm$1.1, 1.9$\pm$1.1, and 1.0$\pm$0.5 hours for computer use, TV watching and exercise, respectively. Milk intake frequencies were positively correlated with excercise, snack frequency, meal balance and regularity, breakfast frequency, food attitude score and milk preference, while showed negative correlationships with TV watching and computer use. Intake frequency of fruit-tasted and chocolate milk showed inverse correlation with nutritional knowledge. Subjects without either school store or vending machine took milk more frequently than those with one or both did. Of the correlated variables, milk preference was the most important influencing factor to milk intake frequency according to the stepwise linear regression analysis, which presented other 5 important influencing factors as food attitude, school vending facilities, excercise, snacking frequency and watching TV. In conclusion, the improvement of milk preference is the most important and effective way to promote milk consumption in adolescents. The favorite ways of drinking milk, nutritional benefit of milk, healthy beverage and good snacking should be taught in nutrition education. Also physical activities should be recommended to students rather than watching TV, computer use and vending facilities selling soft drinks should be limited to be established inside school.

Pear cultivar 'Sinhwa' (Pyrus pyrifolia var. culta Nakai) was originated from a cross between 'Niitaka' and Whasan' with the aims of improving the fruit quality and the traits of cultivation and of early maturing more than 'Whasan' cultivar at Pear Research Station of National Institute of Horticultural & Herbal Science, Rural Development Administration in 1995. 'Sinhwa' was preliminarily selected in 2004 and named in 2009. The tree shows vigorous growth habit and semi-spread characters like 'Niitaka'. Furthermore, it has a sufficient and well upkeep of the flower bud, so it can be more easily cultivated in orchards. In the flower characteristics, flowering time of 'Sinhwa' is $11^{th}$ April like as maternal parent 'Niitaka'. Also 'Sinhwa' has short of pollen grains, so it is need above two pollinizer cultivars. 'Sinhwa' is highly resistant to black leaf spot (Alternaria kikuchiana) and relatively strong to pear scab (Venturia nashicola) in field condition. The optimum harvest time is around Sep. $15^{th}$ in Naju, which is ahead of 'Whasan' about 10 days in the harvest period. The fruit shape is oblate and fruit skin color is yellowish-brown during harvesting time. The average weight of fruit is 627 g, and the soluble solids content is $13.0^{\circ}Brix$. The flesh is very soft and juicy, and renders good eating quality. Shelf life is about 30 days under the room temperature condition.

Purpose : To identify general characteristics of school personnel with recent fatigue which was the most frequent symptom among subjective symptoms and to explore fatigue-related factors by evaluating physical and perceived health status, life style, and symptoms through data mining techniques. Methods : We collected a data of the 1,147(male 545, female 602) who were elementary, middle, or high school personnel, answered a questionnaire, and received physical examination in Seoul School Health Center from September to November in 2000. And we investigated the differences between fatigue group and non-fatigue group for demographic characteristics, physical health status, perceived health status, symptoms, and laboratory values by frequency, chi-square test, t-test, or simple logistic regression analysis by SAS package 8.1, and then selected significant variables as input variables of a decision tree analysis of CART model by SAS E-miner. Results : In general characteristics, the fatigue consisted of 41.1%(male 35.2%, female 46.4%) among 1,147 school personnel. In classical statistics, factors related with fatigue were female, lower means of systolic and diastolic pressure, young age, personnel in middle school, irregular eating habit, no exercise a week or less than 30minutes exercise a day, perception of unhealthy status, and subjective symptoms including short of breath at exercise. In simple logistic regression to examine the relationship between selected independent variables and fatigue as a dependent variable, the odds ratio of gender (female vs male) was 1.58 times, and young age ( 20s vs 60s) 20.67 times, and middle vs high school personnel 1.86 times. However, we mined combined several characteristics by SAS-E miner. In CART model, if health perception was healthy, and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%. Conclusions : The fatigue consisted of 41.1%(male 35.2%, female 46.4%). In classical statistics, fatigue-related factors among school personnel were young age, female gender, perceived unhealthy status, subjective physical symptoms, poor life-style, and lower blood pressure rather than only physical health status. However, in data mining, if health perception was healthy and age was >= 37.5 years, the proportion of the fatigue was only 19.3%. but if health perception was not healthy and symptom was severe 'short of breath' during exercise and age was < 53.5 years, and BMI was >= 22.69, the proportion of the fatigue was up to 84.8%.
