The purpose of this study is to study how college students cope with their stress and how the level of their self-differentiation affects degrees of stress and stress-coping strategies. The questionnaires were handed to 497 college students at Y university in Gyeongbuk Province and the data were analyzed in terms of Cronbach's ${\alpha}$-coefficient, frequency and percentage, t-test, and regression analysis by using the SPSS statistical package. The results of this study were as follows: 1. For stress level, degree of self-differentiation and stress coping strategies of the college students, the average scores were 3.56, 2.53 and 3.49, respectively in 5-point Likert Scale, indicating that the students possess the above-average score for the degree of self-differentiation and stress-coping strategies and the below-average score for stress levels. 2. From examination of difference verification of stress levels based on the degree of self-differentiation and effect of degree of self-differentiation on stress levels, it was found that the higher is the degree of self-differentiation the lower is the stress level. 3. From examination of difference verification of stress-coping strategies according to the degree of self-differentiation and effect of degree of self-differentiation levels on stress coping strategies, we found that the students of higher degree of self-differentiation exercise the more active stress coping strategies. These results show that the degree of students' self-differentiation is a significant variable that influences their stress levels and stress control methods. It is thought that students' self-differentiation functions to minimize their stress and to actively cope with their stressful situation and that a high degree of self-differentiation is a significant mediator variable that is beneficial to students' mental health. It follows from the above observations that while college students in this study seem to possess good degrees of self-differentiation and stress coping capabilities and low stress levels they need to seek for the ways to improve their degree of self-differentiation by seeing into themselves and relationships with others around them. Parents, schools and consultation agencies are required to take an active hand to educate and encourage them to cope with their stress positively.

The purpose of this study is the examination of stress levels and the eating habits that are affected by stress, and the provision of basic nutritional education data for the improvement of the eating habits of students who have experienced stress-related nutritional problems. Using the BEPSI-K instruments, a questionnaire survey was administered to 327 student subjects (166 male and 161 female) in the areas of Seoul and Gangwon province. The subjects were classified into 3 groups (low-stress, medium-stress and high-stress), and 59 students (18%) belonged the high-stress group. The BMI readings of the Gangwon province students are significantly higher than those of the Seoul students. The survey results show that the lunch frequency and vegetable intake levels are lower in the high-stress group, whereas the intakes of hot spicy food is higher in this group; they also show that Gangwon province students had eating habits that are relatively undesirable compared with the Seoul students. There are significant differences between the Seoul students and Gangwon porvince students regarding residence type, household economic level, types of leisure activities and level of some stresses. The Gangwon province students ate occasionally breakfast, lunch and snacks, but their midnight snack consumption is relatively frequent compared with the Seoul students. The results of the survey indicate that the BEPSI-K score has a negative correlation with the following variables : sleeping time, economic level of household, degrees of satisfaction regarding appearance and academic achievements, lunch frequency and vegetable intakes. Desirable eating habits are essential for the maintenance of a favorable health status and for the stress-management of university students who need to be a healthy members of society in the near future. To facilitate the formation of desirable eating habits among university students, community-based nutritional assistance and appropriate nutritional education programs should be considered necessary.

The microbial contamination levels of school classrooms were assessed as foodservice environments for elementary students. Two elementary schools located in Kyunggi-do were selected, and the total plate counts (TPC) and coliforms were measured from the classroom facilities, including the tables, chairs, floors, shelves, doors, as well as the hands of students, and the air of classrooms. The TPC of the classroom facilities were relatively low ranging from 2.30 to 3.79 log CFU/100 cm$^2$. The TPC counts from the hands of serving students and served students, were 6.39 and 5.33 log CFU, respectively, and the TPC counts of the foodservice utensils were <3.00 log CFU/ea before use and 4.77 CFU/ea after use. The air samples of 'empty classrooms during physical education', 'after physical education class', and 'during lunch' showed the contamination levels of 26 CFU/m$^3$,392 CFU/m$^3$, 364 CFU/m$^3$, respectively, suggesting that the microbial levels in the air varies greatly depending on the class activity before foodservice. When the TPCs of the air during lunch were measured from 18 classrooms, the levels ranged from 76 to >2228 CFU/m$^3$. Coliforms were not detected in the classroom facilities; however, air samples of the classrooms showed 1${\sim}$2 CFU/m$^3$. The above results show that classroom air and the hands of students, can have high levels of microbial contamination, which must to be controlled for safer school foodservice.

This study compared nutrition knowledge, dietary behaviors, and checking behaviors of food and nutrition labels between Korean and Chinese university students to obtain useful data for development of an education program for healthy dietary life. The data were collected by a self-administered questionnaire in Korea and China. Frequencies, t tests, ${\chi}^2$ tests, Cronbach's ${\alpha}$, and Pearson's correlation coefficient analysis were conducted by SPSS Win. V.21.0. The levels of nutrition knowledge and dietary behaviors were not high. Korean students showed higher percentage of correct answers about nutrition knowledge and levels of dietary behaviors than Chinese students. The means of degree of checking contents of food labels were 3.46 points for Korean students and 3.11 for Chinese students. Both groups of students showed the highest degree of checking milk and dairy products. The degree of understanding nutritive component labeling of Chinese students was higher than that of Korean students. Both groups of students showed higher than normal levels of confidence about nutritive component labeling and necessity of education on food and nutrition labels. The most preferred method of education on food and nutrition labels was broadcast media for both groups of students.

The purpose of this study was to examine the dietary habits of boarding high school students in Gangwon based on gender and stress levels. Questionnaires were distributed to 571 boarding high school students and collected from 491 students from June 28 to July 20, 2011. The statistical data analyses were completed using SPSS (ver. 19.0) for the descriptive analysis, independent sample t-test and $X^2$-test. The mean stress score was 23.7 out of 40, and male's stress was significantly higher than female's (p<0.05). The rates of having daily breakfast and dinner were significantly influenced by gender (p<0.01), and the regularity of lunch was significantly different depending on the stress level (p<0.05). Female students consumed less flour based foods (p<0.01), carbonated drinks (p<0.01), juices (p<0.05) and functional drinks (p<0.01) than male students, but male students consumed less cookies and breads (p<0.01). Dietary habits that boarding high school students should improve were an unbalanced diet (38%), too much intake at once (17%) and prejudice against foods (11%), and their primary value in dietary life was preference (33%), followed by staving off hunger (18%) and pleasure (18%). The average level of interest in dietary life was 2.46 (on a Likert-type 3-point scale) and it was significantly higher for female students (2.53) than male (2.40) (p<0.05). About 54% of students washed their hands before a meal when they thought of it, but only 25% of students always scrubbed up. The regularity of breakfast and dinner, frequency of snack intake, dietary habits that need to improve, intrest in dietary life, and washing hands before meals showed significant difference by gender but not by stress levels.
