This study was conducted to evaluate the effects of a set of 16 nutrition education lessons on the eating behaviors and nutrition knowledge of middle school students. The target was a group of 128 boys in the first year of middle school in Changwon, who took the classes from the 29th of August, 2011, to the 17th of February, 2012. The education was performed for 16 weeks using the e-learning textbook, 'Health and nutrition of youth', and a teacher's guidebook developed by the Ministry of Health and Welfare. The results were summarized as follows. Students demonstrated significant changes in their knowledge about nutrition and in their dietary behavior due to the nutrition education, and the effects were observed to be maintained for one year after education. The average nutrition knowledge score before, immediately after, and 1 year after the education was significantly increased from 13.0 before the education to 18.8 after education (p＜0.001), maintaining the score of 18.5 1 year later. The eating-related questions of 'I will practice healthy eating habits in life' and 'Nutrition education is necessary to build healthy eating habits', were given a high score by the students at the last survey conducted one year later. Of course, it is not easy to change the dietary behavior of students through dietary education in schools. Nevertheless, the results of this study demonstrated that such educatcan is necessary since the habits can indeed be changed, as observed in the present study.

Eating breakfast provides crucial nutrition for brain function and helps promote overall health. It is especially critical in growing adolescents, as it is known to form good eating habits and better study habits. This study investigated the effects of skipping breakfast on nutritional state, fatigue level, and attention level. A cross-sectional study was conducted in 2010 on total of 828 adolescents composed of 414 boys and 414 girls. Students who ate breakfast never to twice per week were placed in the breakfast-skipper group while students who ate breakfast more than five times per week were included in the breakfast-eater group. Students performed a self-reported questionnaire on food behaviors, amount of food consumption, fatigue level, attention deficient hyperactivity disease (ADHD) level by Conners-Wells’ Adolescent Self-Report Scales, depression scale, and self-esteem level. Statistical analysis was conducted using the SAS program (version 9.1). A total of 135 boys (32.6%) and 138 girls (33.3%) were included in the breakfast-skipper group, whereas 241 boys (58.2%) and 223 girls (53.9%) were included in the breakfast-eater group. The breakfast-skipper group showed irregular food behaviors and lacked nutrients. Specifically, energy (p< .001), protein (p< .001), dietary fiber (p< .001), calcium (p< .01), vitamin A (p< .01), thiamin (p< .05), niacin (p< .001) levels in boy breakfast-skippers were statistically lower compared to boy breakfast-eaters. Intakes of all nutrients except fat in girl breakfast-skippers were statistically lower than in girl breakfast-eaters. Girl breakfast-skippers (41.3%) showed significantly higher fatigue risks compared to girl breakfast-eaters (21.5%). Low attention level was also observed only in girls in the breakfast-skipping group. Moreover, students in the breakfast-skipper group showed higher scores for depression and low self-esteem (p< .001). In conclusion, skipping breakfast has effects on young adolescents’ nutrition, manifesting as high fatigue level and low attention level, especially in girls.

The purpose of this study was to investigate the relationships among snacking behaviors and depression in middle school students. A survey was conducted on 777 middle school students (491 boys and 286 girls). Using a self-reporting method, the participants took 20 minutes to complete the questionnaires. Our data revealed that the height and weight of boys were 172.66 cm and 63.48 kg, respectively, whereas those of girls were 159.86 cm and 51.62 kg, respectively. Sleep durations of boys and girls were 6.44 and 6.41 hours, respectively. Boys ate more rice cake than girls, whereas girls ate more biscuits than boys. The average B.D.I (Beck Depression inventory) scores for boys and girls were 9.73 and 11.49, respectively. Degree of depression was significantly higher in girls compared to boys. We also observed significant correlations between depression and snacking (rice cake, biscuits, chocolate, and fried potato). This study may provide basic information on snacking behaviors and depression in middle school students, and the findings suggest that proper control of emotions is required to maintain desirable eating behaviors in middle school students.

The aim of this study is to provide the fundamental information on satisfaction for school food service and dietary habits of middle school students in Sejong Special Self-Governing City. Generally, the subjects had a high satisfaction level for school food service. The boys had comparatively more satisfactory days for school food service than the girls. The most dissatisfactory factors of school food service were the taste and variety of menu for the girls, and the time and place for lunch and the service of employee for the boys. The intersexual differences existed with a significant difference in the irregular intake of meals, the reasons to skip meals, and the eating speed. For the boys, the main reason to skip meals was due to lack of appetite, and for the girls, it was the weight-control. The boys finished each meal within 5~10 min and ate more than the amount the girls eat in general. The main components of breakfast for the subjects were a cooked rice, soup, and side dish in 65.9%, and the frequency of skipping breakfast was high with 32.8%, which was once per week. The favorite snacks for the middle school students were cookies and beverages in 29.4%, instant foods in 24.3%, and hamburger and pizza in 21.4%. The intake frequency of snacks was once or twice per week in 46.5% of the subjects. In addition, the subjects had a very high intake frequency of fastfoods with once or twice per week in 72.7%, and the most favorite fastfood was ramen in 57.7%. The subjects in 45.3% took dairy food every day. In conclusion, the middle school students need nutrition education to improve their eating habit and to increase the frequency of breakfast.

The purpose of this study is to analyze the physical education avoidance factors and the types of them for seeking the efficient teaching methods of physical education and making an appropriate learning environment which result in vitalized physical education. For this purpose, this study is planned to gain specific evidences. From May to July in 2013, the research has been conducted in Gangseo, Yangcheon, and Mapo area of Seoul. Among 420 of female middle school students who are the subjects originally, 349 of students are used as a data of spss 12.0 statistics. The conclusion is deducted by one-way ANOVA, corelation analysis, and multiple regression analysis based on the analysis contents and purpose. the conclusions were as follows; Firstly, as examining the avoidance factors of female middle school students from the background variables, the second grade students of middle school recognize the avoidance factors highest among sub factors based on the grades. In respect of the avoidance factors based on the school form, female students of coeducation school perceive the avoidance factors more than ones of girls' middle school. While female middle school students taught by male teachers are more aware of students factors, course contents factors, and weather factors, the students who are taught by female teachers recognize facility-instrument factors, teacher-teaching factors highly. In the avoidance factor based on whether a school has gym or not, middle school female students without gym perceive course content factors, teaching factors, and weather factors highly. On the other hand, middle school female students who do not have gym recognize student factors more than others. Secondly, in the case of avoidance types of middle school female students, second graders mark the highest states on not only the active avoidance but the passive one. While first graders are higher than third graders on the active avoidance, third graders appear highly on the passive avoidance compared to first graders. According to the types of school, middle female students in coeducation school avoid more on both active and passive avoidance. Based on the gender difference of the teachers, middle school female students who are taught by male instructors show the higher passive avoidance than ones taught by female instructors. Inversely the latter show higher avoidance on the active avoidance. Middle school female students who don’t utilize a physical training facility turn out having high tendency on both the active and passive avoidance. Thirdly the meaningful positive relationship between the physical education avoidance and the avoidance types exists. In the case of the active avoidance of physical education, students are influenced by teaching and weather factors meaningfully. Students factors, course content factors, and weather factors have meaningful influence on the passive avoidance. From all the features above, middle school female students have different avoidance factors based on the background variables. Also their avoidance types of physical education vary depending on the background variables. The avoidance factors of physical education have effects on the types of the avoidance.

To study the importance of family meals in adolescents, 251 middle school students were surveyed through a questionnaire on their family meal patterns, dietary behaviors, food intake, and life satisfaction. The family meals were defined as "meals with all family members living together" by 62.2% of the students. For the frequency of family meals, 42.2% of the students replied having family meals "More than once a day". A common reason for the difficulty in having a family meal was a "lack of time" (73.3% of the students). Students tended to respond that they would be most fond in having meals with entire family members with traditional Korean food. Having more frequent family meals was found to benefit both individual and familial dietary behavior. In terms of food intake according to the frequency of family meals, the group having frequent family meals consumed significantly more rice, tofu, legumes, meats, fishes, eggs, green vegetables, seaweeds, fruits, milk, and milk products. This indicates that students can achieve a balanced diet through family meals. In terms of emotional status, the group having more frequent family meals showed a higher satisfaction with their daily life, health, nutritional status, and care from their relatives. In terms of personal mental status, the group having more frequent family meals was also found to be more effective at controlling undesirable emotions such as loneliness, indignation, and lethargy. As a result of this study, students in the group having more frequent family meals were found to have a positive dietary behavior, a balanced nutrition, a higher life satisfaction, and a more stable mental status. This result is useful as nutritional and educational information in schools to impress upon the public the importance of family meals for adolescents.

This study examined whether explicit or implicit teaching is more efficient in improving Korean middle school students’ English verb−noun collocation knowledge. Forty Korean EFL middle school students participated in the study and they were assigned to either the explicit instruction or implicit instruction group. The participants’ English verb−noun collocation knowledge was measured through pre-, immediate post-, and delayed post-tests over the 5- week experimental period, and a survey of participants’ opinions on the instruction they received was carried out. The results showed that the students who received the explicit collocation instruction displayed better learning outcomes, suggesting the immediate influence of the explicit instruction, and more importantly the sustained initial advantage. That is, the explicit group students did retain the target items significantly better than the implicit group students. The responses from the two groups also indicated the positive effects of the explicit collocation instruction. The explicit group students were mostly satisfied with the instruction and showed increased confidence in acquiring English collocations while the implicit students did not. This study provides L2 teachers with valuable information on how to teach L2 collocation more effectively.

he purpose of this study is to offer youth with the basic materials for developing nutrition education programs and to help domestic science teachers in schools implement effective dietary education by examining their awareness of food additives. In the source of acquiring knowledges on food additives, the results were through mass media, technology and home economics teachers, and family members in order. The majority of students thought that they don't need the education about food additives. As effective teaching methods, they first selected the use of visual media, followed by experimental cooking classes, field trip, and inquiry lessons using processed foods. As a result of analyzing the education on food additives in accordance with demographic factors, more number of female students, compared to male students depicted the need for education on food additives. Further, the lower the cost students spend on purchasing processed foods per day, the higher the necessity of the education they indicate. The necessity of education content on food additives showed significant difference depending on the cost of buying processed foods, and the degree of interest and help real-life according to gender indicated significant differences. The satisfaction with education on food additives, which was implemented in home economics education revealed significant differences according to gender. This study aims to provide the basic data for the development and research of educational programs regarding good eating habits among the general youth. However, there are limitations to the presentation of the practical training program. For this reason, based on the results of this study, further studies should follow this study in order to develop and study educational programs related to food additives for teaching and learning purposes.
