  • 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.

  • This study was performed to investigate added sugar intakes from processed food-snacks and participation behaviors of special event days sharing sweet foods among adolescents in Korea. Questionnaire survey (n = 959), dietary survey (n = 71) by food record method for 3 days, and snack survey (n = 230) for 3 days were carried out, and subjects were overlapped among three surveys. As a result, middle school students (MS) preferred milks and fermented milks while high school students (HS) preferred breads and fast foods as a snack (p < 0.01). MS and HS took snacks three to six times a week, and HS took snacks more frequently than MS (p < 0.05). Most subjects participated in special event days sharing sweet foods such as friend's birthday (68.4%), Peppro's day (61.5%) and Valentine's day (42.6%). As for merits of these events, MS said ‘they could get along with their friends' and ‘relieve stress', while HS said ‘they could enjoy their own events' and ‘confess their affection to whom they like' (p < 0.01). A group of cookies, biscuits, breads and, cakes was major source of added sugars followed by beverages, sweet jellies of red bean, chocolates and candies for subjects. For MS and HS, daily total added sugar intakes from whole processed food-snacks were $30.5{\pm}23.5g/d$ (3.0-137.9 g/d) and $31.7{\pm}23.2g/d$ (1.2-126.1 g/d), and ratios of daily total energy taken from added sugars of whole processed food-snacks in proportion to daily total energy taken from diet (energy percent of added sugars from snacks) were $6.3{\pm}4.7%$ (0.6-26.1%) and $6.3{\pm}4.4%$ (0.3-23.9%), respectively. These results showed that subjects frequently participated in special event days sharing sweet foods. In addition, energy percent of added sugars from snacks was more than the UL suggested by WHO/FAO for some subjects. Therefore, it is highly critical to monitor adolescents' sugar intakes on a long-term basis and to take nutritional management on their high sugar intakes.

  • Purpose: The objective of this study was to investigate the differences of sodium intake in the diet according to the kind of meal, food group, and dish group. Methods: A dietary survey was conducted using the 24-hour recall method from April to May, 2009. The study subjects consisted of 701 elementary and 1,184 middle school students in the Jeju area. Mean sodium intake and the percentage contribution of meals and each dish and food group to daily sodium intake were calculated. Results: The daily sodium intake was 2,868.4 mg and 3,032.5 mg in elementary and middle school students. For elementary school students, breakfast, lunch, dinner, and snack provided approximately 18.0%, 35.1%, 32.8%, and 14.1% of total daily sodium intake, and for middle school students, 15.3%, 40.2%, 29.1%, and 15.5%, respectively. Major food groups for sodium intake were spices (1,252.5 mg in elementary, 1158.0 mg in middle school students), vegetables and their products (409.0 mg, 495.6 mg), cereal and grain products (322.4 mg, 647.8 mg), and fish and shellfish (255.3 mg, 336.6 mg). Except cereal and grain products, sodium intake of the food groups mentioned above was greater at lunch and dinner than at breakfast and snack. And, the elementary and middle school students obtained 5.9% and 9.8% of total daily sodium intake from cereal and grain products at snack. Among the 29 dish groups, the highest dish groups contributing to dietary sodium intake were soup and stew and tang/jeongol, consuming 19.8% (elementary school students) and 25.4% (middle school students) of daily sodium intake. The following major dish groups contributing to dietary sodium intake, in order, were kimchi, seasoned vegetables, grilled dish, stir-fried dish, and $\grave{a}$ la carte. By meals, the percentage of sodium intake from soup, kimchi, stew, fried dish, and stir-fried dish at school lunch was high, from noodles, grilled dish, and $\grave{a}$ la carte at dinner, and from bakery/snacks and noodles at snack. Conclusion: Sodium intake from the various side dishes at school lunch was high and noodles and bakery/snacks were popular snack foods in elementary and middle school students in Jeju area. In order to lower the intake of sodium, students need to be educated about eating less soup and choosing better snacks.

  • This study was conducted to explore the mediation effects of irrational belief on the relationship between game addiction and anger behavior. For this study, 431 middle school boys in Chungcheong areas were included in the analysis. The results showed that game addiction was positively correlated with direct anger-out, rumination, diffusion as well as irrational belief. The boys at high risk of game addiction showed higher mean scores on irrational belief, direct anger-out, rumination: and diffusion than other students. Irrational belief (mediator) partially mediated the influence of the boys' game addiction (independent variable) on direct anger-out, rumination, and diffusion (dependent variable). Finally, limitations of this study and suggestions for future study were discussed.

  • The purpose of this study was to examine the mediation effects of impulsiveness on the relationship between boredom proneness and game addiction. For this study, 364 middle school boys in Kyungki and Chungcheong areas were included in the analysis. The results showed that boredom proneness was positively correlated with impulsiveness and game addiction. Impulsiveness was found to fully mediate the influence of the boys' boredom proneness (independent variable) on game addiction(dependent variable). Based on these results, strategic interventions including impulsiveness control and self-leadership training were suggested to prevent game addiction.

  • The purpose of the study is to meta-analyze research results on Korean students' logical thinking ability. The results of meta-analysis on the research studies between the year 1980 and the year 2000 show that about 40-50% of Korean middle school students have conservation reasoning, proportional reasoning and combinatorial reasoning abilities, and that about 25-30% of them have control of variables and probability reasoning abilities. In addition, only 8% of the Korean middle-school students have correlational ability. When comparing their logical thinking ability results with those of Japanese and American middle-school students, The ratio (32.6%) of Korean middle-school students who have formal thought ability is a little higher than that of American students (30.6%), but much lower than that of Japanese students (50.1%).
