This study was performed to investigate the relationship between milk consumption, dietary nutrient intake, and physical strength in Korean adolescents for dietary education of home economics subject at middle and high schools. Intake of milk and milk products, that of dietary nutrients, and physical strength records were surveyed for 298 high school students resided in small and medium-sized cities in Korea. Intake of milk and milk products was collected from three-day dietary survey, and daily dairy equivalent of calcium was calculated by dividing daily calcium intake(mg) from milk and milk products by calcium content(200 mg) of 200 mL milk. Dietary survey was performed during three days including two-weekdays and one-weekend by food record method. Dietary nutrient intake was analyzed by CAN-Pro 3.0. Physical strength records were offered from subjects' schools. Subjects were divided into low intake group(${\leq}0.29/d$), medium intake group(0.30-0.78/d) and high intake group(0.79-5.66/d) according to daily mean dairy equivalent of calcium taken by them, and most of them consumed milk and milk products less than '2' of the recommended value. Daily mean dairy equivalent of calcium was significantly related with high records of '50 m running' and 'stand long jump'(p<0.05), however it was not related with other records of physical strength. Intakes of energy, carbohydrate, protein, fat, calcium, phosphorus, iron, zinc, thiamin, riboflavin, niacin and vitamin E were significantly correlated with high record of '50 m running'(p<0.01). Intakes of nutrients were related with '50 m running' except fat were significantly correlated with high record of 'stand long jump'(p<0.05). Intakes of protein, phosphorus, iron, zinc, vitamin A, $B_6$ and E were significantly correlated with high record of 'long distance running'(p<0.05). In conclusion intake of milk and milk products was related with physical strength records('50 m running' and 'stand long jump') and intakes of most nutrients including energy nutrient, vitamin and mineral were correlated with physical strength records('50 m running', 'stand long jump' and 'long distance running') in Korean adolescents. Therefore, optimal consumption of milk and various nutrients for balanced nutrition during adolescents should be emphasized in dietary education of home economics subject for their strong physical strength.

In this study, the effect of clothing color preferences of adolescents on their self expression desires and fashion interest were investigated. These investigations were intended to understand some psychological aspects of adolescents and to make a contribution to guiding them in forming self identities and expressing themselves confidently through clothing. This research was based on 452 copies of questionnaires distributed to middle and high school students living in Seoul and other metropolitan areas from the middle of March to the beginning of April, 2008. The results were as follows. First, there was a significant difference in clothing color preference and clothing color tone preference between male students and female students. Second, the factor analysis which has been performed by taking assimilation, individuality, recognition, and image management as composing dimensions of self expression desire shows significant differences between these dimensions. Third, the difference in the self expression desires according to clothing color preference showed that the group preferring cool colors and the group preferring warm colors possessed the same highest self expression desires. And, it was revealed that the clothing color preference was a significant variable influencing fashion interest. Fourth, the effect of self expression desire on the fashion interest degree showed that recognition was the most significant factor and image management was the next.

The purpose of this study was to verify the effectiveness of sociodrama on adolescents who are maladjusted in school. For this study, nine adolescents were selected from a middle school located in Seoul. The Inventory of School adjustment by Bae Sook-Jin, Buss-Durkee Hostility Inventory(BDHI) and Impulsivity Test by Eysenck were administered. The experiment group acted out a sociodrama twelve times. The first follow-up test was conducted twelve weeks after the pre-test. The second follow-up test was conducted six weeks after first follow-up test. Each time the adolescents acted out a sociodrama their behavior was recorded by a video- camera and then documented by research assistants. Also in order to discover any changes in daily life after sociodrama, an interview survey were done with the adolescents' teachers. The findings were as follows. First, in the initial follow-up test degree of school-maladjustment was less than in the pre-test. Further decreases in the level of maladjustment were noted in the subsequent follow-ups. Therefore, it can be concluded that the performance of sociodramas can reduce school-maladjustment among adolescents and that this reduced level is maintained. Second, the level of hostility discovered in the first follow-up test was less than that in the pre-test, and this level continued to decrease in the following follow-ups. Therefore, we may conclude that sociodrama that reduces adolescent hostility and the reduced levels continue. Finally, the degree of impulse detected in the first follow-up was, once again, less than that of the pre-test, And, as in the other cases, there was a continued decrease in this level. We may therefore conclude that sociodrama does reduce the impulse of adolescents and that this reduction is maintained. This study indicates that sociodrama is an effective method to improve the psychological characters of adolescents who are maladjusted in school. Given the above, a follow up study is suggested.

The main purpose of this study was to examine the effects of maternal achievement pressure and emotional support on adolescents' achievement motivation. A total of 241 adolescents in the second grade of two middle schools in Seoul and their mothers participated in the study, and completed questionnaires on mothers' achievement pressure and emotional support. Adolescents also answered a questionnaire on achievement motivation. Sohn's(1997) Achievement Pressure Scale, Sung's(1993) Social Support Scale and Hermans'(1970) Prestatie Motivatie Scale were used for this survey. Data were analyzed by Pearson's correlation coefficients, t-tests, regressions, and one-way ANOVA with Duncan's multiple range tests. Results showed that maternal achievement pressure and emotional support and adolescents' achievement motivation did not vary as a function of sex. Maternal achievement pressure and emotional support had positive effects on achievement motivation of adolescents, and maternal achievement pressure played a more influential role on the motivation of adolescents than emotional support. Among four groups divided by the level of maternal achievement pressure and emotional support, high/high, high/low, low/high, and low/low, adolescents in the high/high group were perceived to have the highest achievement motivation. Findings suggest that both maternal achievement pressure and emotional support are important in improving adolescents' achievement motivation.

This study was conducted to investigate the relationship among the current status of calcium intake from milk and milk products, physical growth and bone mineral density in 664 male and female middle school and high school students aged 15-17 years. In the study, the current status of calcium intake from milk and milk products was analyzed, and the height, body composition, and bone mineral density of the right heel bone (calcaneus) were measured. The daily calcium intake of milk and milk products was calculated as the 'dairy equivalent of calcium', which is the calcium content in 200 mL of white milk. The cutoffs of tertiles of the dairy equivalent of calcium were calculated and then the subjects were categorized into 3 groups according to the tertiles, Q1 group (lower intake group), Q2 group (middle intake group) and Q3 group (upper intake group). The daily calcium intake of milk and milk products in Q1, Q2 and Q3 groups was 16.2 mg, 99.7 mg, and 284.0 mg, respectively, and the ratio of milk and milk product consumption to the daily total calcium intake was 5.4%, 27.4%, and 49.7%, respectively. The ratio of total calcium intake to the daily recommended intake in study subjects was 30.5% in Q1, 42.3% in Q2, and 60.7% in Q3, with significant differences (P < 0.05). Height, body weight, BMI, and % of body fat in three tertile groups (Q1, Q2 and Q3) were not significantly different. However, the T scores for bone mineral density in female students in three tertile groups (Q1, Q2 and Q3) was significantly different (P < 0.05). The study showed that the intake of milk and milk products in adolescents, particularly in girls, can improve the bone mineral density without increasing body weight, and thus confirmed that milk intake is important in adolescence.

This study assessed the nutrient intake for Korean adolescents using the estimated usual intake. The usual intake of 1,763 adolescents aged 12-17 years old was estimated from one-day 24-hour recall data in the 2010-2012 Korean National Health and Nutrition Survey. The nutrient intakes of four groups according to sex (male and female) and age (12-14 and 15-17 years old) were then assessed in reference to the 2015 Dietary Reference Intakes for Koreans. For macronutrients, the proportions of subjects below and above the Acceptable Macronutrient Distribution Ranges (AMDR) were calculated. The Estimated Average Requirement (EAR) cut-point method was used to assess insufficient intakes of protein, vitamin C, thiamin, riboflavin, niacin, calcium, phosphorus, and iron; the full probability approach was used to assess the insufficient intake for iron among females. The proportions of subjects over the Tolerable Upper Intake Levels for vitamin C, niacin, calcium, phosphorus, and iron and the proportions over the Intake Goal for sodium were calculated to assess excessive intake. The proportions of subjects above AMDR for carbohydrates ranged from 22.5% to 38.0% by group. The proportions of subjects by group with insufficient intake for vitamin C, riboflavin, calcium, phosphorus, and iron ranged 29.1-39.7%, 22.5-34.3%, 73.1-89.3%, 14.3-43.6%, and 23.2-55.5%, respectively. The proportions of subjects by group with excessive intake for sodium ranged from 91.5% to 99.3%. The results of this study represent important basic information to establish nutritional standards for school lunches as well as to decide on relevant nutrition policies for adolescents.

The purpose of this study was to investigate the evaluation of regional antagonism in children and adolescents in Youngnam and Honam region. There were 684 subjects included in this study from three ages in the Youngnam and Honam regions: 12.8 years(6th grade, n=208), 14.8 years(8th grade, n=211), and 16.9 years(10th grade, n=265). Of the 684 subject, 357(53.3%) were boys and 327(47.8%) were girls. The instruments consisted of subjects' self-reported social distance, stereotype, and prejudice. The data were analyzed by frequencies, t-test, one-way ANOVA and the $Scheff\'{e}$ test. Major findings were as follows: The mean score of the out-group stereotype was greater than the median, so the in-group preference was greater than the out-group exclusion. The in-group stereotype was different based on the age and the sex. The 6th and 8th graders and the boys were higher than 10th and the girls. The prejudice was different based on the lesion. The social distance was different based on the age and the region.

Objectives: Maintaining a balanced diet is very crucial for adolescents. However, adolescents, who may have a short notion about the amount of food, find it difficult to plan daily meals by applying the target pattern proposed by the Korean Nutrition Society. This study was carried out to revise the target pattern based on cooked dishes instead of raw material food groups as an easier way for Korean adolescents to plan their meals. Methods: Target pattern for Korean adolescents were revised based on the following: $1^{st}$, categorize dish groups, $2^{nd}$, calculate representative values of each dish based on the adolescent' intake amount. $3^{rd}$, assign the recommended number of intake for each dish. Validity of the target pattern for Korean adolescent meal plan was examined by the energy content, energy contribution ratio, and NAR & INQ of nutrients. Results: The 11 dish groups categorized were bab; gook tang gigae; side dishes of meat, fish, egg, legume, kimchi, vegetable, seaweed; and between meal of fruit, and milk dairy product. Based on the representative energy values, recommended number of intake were assigned to each dish. For boys, bab and gook tang gigae: 3 each; meat, fish, egg, and legume: 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. For girls, bab and gook tang gigae: 2 each; meat, fish, egg, and legume: choice of 3 dishes, 1 each; kimchi and vegetable: 3 each; seaweed: 1; fruit and milk dairy product: 2 each were assigned. Energy contents, energy contribution ratio of carbohydrate, protein, and fat for boys and girls were in adequate range. The NARs were 1.0 and INQs were ${\geq}1.0$ for all nutrients examined. Conclusions: Revised dish-based, instead of food-based adolescent target patterns for boys and girls were easier and a valid way of Korean adolescent meal planning.

This study intended to analyze the ethical clothing consumption behavior of female adolescents and use it as a basic data for education. Specifically, the female adolescents were classified according to their shopping orientation and then the differences among these groups were examined in terms of their ethical consumption behavior of clothing products, i.e., buying, using and disposing. As a result, three groups were identified: pleasure-seeking, intermediate, independence pursuing according to the shopping orientation sub-factors (loyal, enjoyment, impulsive, imitative and independent). The pleasure-seeking group were more likely to conduct ethical use behavior of clothing products, while the independence-pursuing group conducted more ethical buying and ethical disposing behavior. The lower their desire to enjoy shopping itself, the more cautious they are about their own decisions, and the more confident they about buying from the brand and store they liked, the more likely they were to conduct ethical buying behavior of clothing products. On the other hand, when the emotional and desire-seeking tendencies are combined with independent shopping tendencies, the more likely they conduct ethical use behaviors. In addition, the more they make independent purchasing decisions, the more likely they are to conduct ethical disposal behaivors. The results of this study suggest that providing detailed consumer education that considers individual differences in shopping orientation is needed.
