The subjects of this study were three elementary schools in Andong, which were selected randomly and 120 students randomly selected from 4th to 6th grade for a total of 360 students. The questionnaire was composed with the help of a community health nursing professor and through the reference review. The collected data were analysed by a PC SPSS 10.0 according to school grade and sex, an 12-test was implemented to learn what percent of students have computers and software which prohibit the viewing of online pornography, access motivation and time, content viewed, attitude after accessing the contents, and opinions about computer online pornography. The results of this study were as follows. 1. A total of 86.1% of students had computers at home. Most students placed computers in their own room, 78.9% of students had computer online communication experience. Higher grade students tended to have more experience of communications on the internet (P<0.001). Most students chatted on the internet once or twice a week and higher grade students tended to communicate online more frequently. (P<0.001). Most students used computers more than one hour a day (P<0.05). They used computers according to the following priorities: game, studying, listening to music, communications, chatting. 2. Regarding the frequency of going computer online more than seven times per week, male students showed a higher frequency than female students (P<0.05). Male students used computers more than one hour a day and female students less than half an hour (P<0.001). Male students mostly used computers to play computer games.

The purpose of this study was to assess pro-environmental behavior of elementary school students by school year and gender and to investigate the relationships of their emotional affinity toward and intellectual curiosity about life, and experiences about nature and life with the pro-environmental behavior. A total of 436 elementary students participated in the study: 189 3rd grade; 247 6th grade students, and 233 boys; 203 girls. The variables were measured by using a self-report questionnaire with 5-point Likert scale items. The results showed the levels of pro-environmental behavior of the 3rd grade students and the girls were higher than that of the 6th grade and the boys, respectively. Their pro-environmental behavior was significantly related with all measured variables. However, it was found that the direct predictors of their pro-environmental behavior were the intellectual curiosity and the indirect experience, while the emotional affinity and the direct experience did not have a direct impact on the behavior. The predictive power of the intellectual curiosity and the indirect experience for their pro-environmental behavior was higher in 3rd grade than 6th grade. While the indirect experience was a stronger predictor of the boys' pro-environmental behavior than the intellectual curiosity, the curiosity was a stronger predictor of the girls.

The study in this paper, which is part of a bigger study investigating non-cognitive characteristics of Korean students at the 4-12 grade levels, aims to identify the influential characteristics that explain students' decision to give up on mathematics learning. We consider seven non-cognitive student characteristics: value, interest, attitudes, external motivation, internal motivation, learning conation and efficacy. Data were collected from 21,485 Korean students, and were analyzed with a logistic regression method using SPSS. The findings show that efficacy was the most significant indicator of students' decision to give up on mathematics learning in all three grade level bands: elementary (4th-6th), middle (7th-9th) and high (10th-12th). In particular, the causal model analysis shows that students who highly value mathematics tend to have stronger internal and external motivation, which bring about stronger interest and learning conation, which in turn lead to positive attitudes and strong efficacy regarding the learning of mathematics. It was further found that while external motivation was a significant indicator of upper grade level students' decision to give up on mathematics learning, it was only a moderate indicator for lower grade level students. The findings of this study provide useful information about which non-cognitive areas need to be focused on, in what grade levels, to help students stay on track and not fall behind in learning mathematics.

The purpose of this study is to analyze the differences between the cognitive load of mathematics textbooks based on storytelling and traditional mathematics textbooks that are presented to students. In order to verify this, we have selected two 4th grade classes in elementary school that were identified as a homogeneous group through prior testing, and thus were separated into experimental group and comparative group. Then, without the teacher's lessons, the experimental group learned from mathematics textbooks based on storytelling and the comparative group learned from traditional mathematics textbooks. Afterwards, the two groups' cognitive load was measured through a questionnaire, and the following results were obtained: In the 'mental effort' and 'self evaluation' categories, the students that learned from the mathematics textbook based on storytelling showed higher scores than the students that learned from the traditional mathematics textbook. also there was statistically significant difference in some items. However, no statistically significant difference was found in the remaining categories 'task difficulty', 'self evaluation', and 'material design'.

This study was targeted at 91 students living in a boys' high school dormitory and centered on the how the consumption of fish and vegetables changed after students were educated according to nutrition education and cooking methods. First of all, the primary investigation of the leftover amount in the beginning of the semester was conducted five times for five days from March 21st to 25th, 2011. The secondary investigation was conducted with the same diet for five days as well from December 1st to 7th. Then the tertiary investigation was performed eight times from December 12th to 30th, after cooking method changes. There was a difference of the total leftover food amount between the first grade and the second grade during the beginning of the semester, but after the nutrition education there was no difference of the leftover food amount. In particular, leavings of vegetables and fish both significantly decreased in the first grade, after the nutrition education to encourage students to eat fish and vegetables. However, there was no difference in the leftover food amount of the second-grade students who received the education before, between the beginning and the end of the semester. When cooking fish the way students preferred, they had fried fish fillets the most, followed by roasted fish fillets, roasted bone-in fish, and braised fish. There were significant differences. Regarding vegetable, students ate salad the most, followed by Geotjeori and blanch, and there were significant differences.

Purpose: The aim of this study is to investigate the relation of the unhealthy eating habit of high school students in Seoul with their school types. Methods: In cross-sectional study, secondary data was used, representative sample of 7,284 subjects, high school students in Seoul. Consumption rates of Ramyun, Fast-food, and a breakfast-skipping rate were compared by the gender, grade, and school type. Descriptive statistics, ${\chi}^2$ analysis, correlation, and multiple logistic regression were used for data analysis. Results: The odds ratios (OR) of associated factors on the breakfast-skipping were 1.25 times higher in the 11th grade, 1.26 times in the 12th grade (reference: 10th grade), 1.21 times in school for both gender (reference: only male gender), 2.63 times in the general high school, 4.82 times in the vocational (reference: the autonomous private). The odds ratios (OR) of associated factors on frequent Ramyun intake were 2.10 times in male, 1.79 times in both gender (reference: only male gender), 2.01 times in the general high school, vocational 5.26 times (reference: the autonomous private). The odds ratios (OR) of associated factors on frequent Fast-food intake were 1.89 times in school for both gender (reference: only male gender), 3.93 times in the vocational high school (reference: the autonomous private). Conclusion: Students of the vocational high school than those of the autonomous private had more and more the breakfast-skipping rate, and had more consumption rates of Ramyun and Fast-food.

The purpose of this study is to examine the effect of the sex education program on the elementary school students' sex-related knowledge and attitude. The research method used in this study is an equivalent control group pre-test and post-test and post-test design in a quasi-experimental research format. The subjects of this study were the 5th-grade elementary school students(63 in the experimental group and 60 in the control group) in O and O elementary school in G city. The data was collected from April 4th to July 3th, 2003. The experimental group received a sex education program while the control group did not receive any treatment. The sex education program was implemented for 40 minutes every 2-3 days which total twelve sessions over 4 weeks. Using the SPSS 10.0 program, the data was analyzed by $X^2$ - test, Fisher exact test, t-test, and a repeated measures ANOVA., Rrsults : The experimental group who received the sex education program showed a significantly higher sex-related knowledge score than the control group (F=140.52, p=.001). The experimental group showed a significantly higher sex relatied attitudes score than the control group (F=40.80, p=.001). This study concluded that the sex education program was effective in both sex-related knowledge and attitudes for elementary school students. Therefore, it appears to be effective for 5th-grade students to receive intensive sex education. It es recommended that the schools and government develop education media and a sex education program for parents, have a sex education teacher and a place where students can be counseled, and a professional consultant who can effectively counsel the students regarding sex-related issues.
