Seven hundred eleven healthy middle-aged women, aged 40 to 64, and were a convenience sample by stratified ratio using the matching fixed residential and aging blocks. The data were analyzed by GLM. Pearson correlation coefficient and Scheffe test using SAS/ PC+. The results were summarized as follows : 1. The percentage of psychological stress with the following items was: fatigue and enervation, 70.0%; nervous, 61.8%; weakness, 58.5%; The percentage of physical stress with the following items were ; fatigue of eye. 82.3%; backache, 78.0%; headache, 73.8%. 2. The level of psychological stress was 40% of below average level (0-5 points), 31.7 of average level (6-12points), 20.8% of precaution level (13-19 points), and 7.5% of warning level (over 20points). The level of physical stress were 20.1% of below average level (0-5 points), 34.8 of average level (6-12 points), 29.4 of precaution level (13-19 points), and 15.7% of warning level (over 20 points). There were higher physical stress level than psychological stress level of the subjects. 3. The percentage of climacteric symptoms with the following items were : numbness, 75.3%; forgetfulness, 71.0%; pain of joints, 71.0%. The level of climacteric symptoms were 61.8% of mild level 1(10-15 points), 33.0% of moderate level (16-30 points), 5.2% of severe level (over 31 points). 4. There were high positive correlations significantly between the climacteric symptoms and the psychological stress (r=.564. P<0.000), and between the climacteric symptoms and the physical stress of the subjects(r=.678, P<0.000). 5. There were significant differences in the climacteric symptoms of the subjects among below average level, average level, precaution level, and warning level of the psychological stress (F=74.108. P<0.000. Scheffe test). 6. There were significant differences in the climacteric symptoms of the subjects among below average level, average level and precaution level, and warning level of the physical stress ((F=128.181, P<0.000, Scheffe test). In summary, climacteric symptoms complained by middle-aged women are high positive correlated to the level of the stress. Also climacteric symptoms were affected by stress.

This study was conducted to evaluate the eating behavior and to analyze the various factors affecting eating behavior among middle school students. The subjents consisted of 212 middle school students(106 boys and 106 girls between 13-14 years) residing in Seoul. A questionnaire was used as the questionnaire consisted of four parts : the socio-demographic characteristics of the subjects, value toward food and nutrition, diet diversity(the number of food items) and eating behavior. Results showed that fifty three point five percent of males and fifty seven percent of females skipped breakfast. The main reason for skipping breakfast was shortage of time. Fifty five percent of the total number of subjects stated that they had more than two plasant meals a day. The number of food items eaten was significantly higher in males than in females. In only 16.4% of total subjects(18.5% of male and 14.2% of female), the primary pursuit in having meals was not to satisfy hunger but to consider nutrition and health. The eating behavior of the adolescents showed that 65% of the subjects had a 'good' eating behavior score and 17.4% had scores of 'excellent' and 'poor' respectively. The existence of parents, the economic level of the family, and concern of health and nutrition affected the eating behavior score. The less the subject skipped breakfast, the greater they placed a value toward food and nutrition. Value toward food and nutrition had a significant influence on their eating behavior. Those who placed a value toward food and nutrition had a higher eating behavior. Those who placed a value toward food and nutrition had a higher eating eating behavior. As a result of the multiple regression analysis, factors affecting eating behavior were 'pleasant meal' , 'the value toward food and nutrition' and 'the numbers of food items' in order(R2=0.2984).

The purpose of the study was to examine the adolescents' awareness and practice of Dietary Action Guide for Adolescence, which was developed by the Ministry of Health & Welfare. Subjects were middle and high school students, selected one class each from all of the 16 provinces in Korea, which were 32 schools and 998 students all together. The subjects were asked to self-evaluate the degree of awareness and practice of Dietary Action Guide using the 5 point-Likert scale from July to September, 2010. On average, 55.1% of the students responded that they were aware of the Dietary Action Guide and 49.4% answered that they put Guidelines into practice. The average score of awareness and practice were $3.54{\pm}0.24$ and $3.42{\pm}0.33$, respectively. The awareness score was higher than those of practice score in all the questions in the 6 categories. Awareness score of female students was higher than those of male students but there was no difference by residence area. Awareness and practice of the nutrition education-experienced were higher than those of the inexperienced. Practice score was higher among middle school-students compared to high school students, which reflected the opportunity of taking nutrition related classes. This finding shows that nutrition education for adolescents is important to change their dietary behaviors regardless of gender, residence area and school level.

Textbooks are official materials so that these are the most frequently used teaching materials in school. The teacher constructs the lesson based on the contents of the textbook to achieve the learning goal. Thus, textbooks play an important role because the quality of the contents in textbooks affects the cognitive level of students. This study investigates the cognitive domain based on Bloom's Taxonomy of Educational Objectives(knowledge, understanding, application, analysis, synthesis and evaluation) of 'Values and Expression' in the mathematics textbook of the first grade of middle school reflecting the 2015 revised mathematics curriculum. We also looked at cognitive levels based on Bloom's Taxonomy of Educational Objectives. As a result, it was found that understanding was dominant in 'Values and Expression'. Also, although the problem of requiring a higher level of cognition is increasing as the unit finishes, there are still a high percentage of low level of problems.

The purpose of this study is to see relationship between middle school students' cellular phone consumption behavior and their mothers' consumer education. A survey was conducted with middle school students at nine middle schools in Gyeongnam who possessed a cellular phone and their mothers(1,080 in total). The results of this study are as follows: First, middle school students' cellular phone consumption behavior was relatively at the average level or higher: they were best at A/S and change and refund and were at the average level in collecting and using information for purchase followed by contract. This consumption behavior was associated with such variables as gender, academic performance, and monthly pocket money. Second, as for consumer education for middle school students' mothers in general, purchase education was most highly recognized, followed by citizenship education and value education. However, value education was relatively weak, which should be reinforced. Mothers' consumer education was associated with children's grade, academic performance and monthly pocket money. Third, since middle school students' desirable cellular phone consumption behavior was strongly associated with their mothers' consumer education, it is highly urgent to improve the quality of consumer education by mothers at home.

In this study, reliabilities of holistic scoring method and analytic scoring method were analyzed in performance assessments of middle school students' science investigation activity. Reliabilities of 2, 3, and 4~7-level rubric ratings for analytic scoring methods were compared to figure out optimized numbers of rubric ratings. Two trained raters rated four activity sheets of 60 students by two rating methods and three kinds of rubric ratings. Internal consistency reliabilities of holistic scoring methods were higher than those of analytic scoring methods, while intrarater reliabilities of analytic scoring were higher than those of holistic scoring methods. Internal consistency reliabilities and intra-rater reliabilities of 3-level rubric rating showed similar patterns of 4~7-level rubric ratings. But students' discriminations, item difficulties and item-response curves showed that the 3-level rubric ratings was reliable. These results suggest that holistic scoring method could be adapted to increase internal consistency reliabilities with improvement in intra-rater reliabilities by rater's conferences. Also, the 3-level rubric rating would be enough for good reliability in case of adapting analytic scoring methods.
