The purpose of this study is to examine the effects of extracurricular activities such as creative experiential activities, life guidance, and counseling activities on school satisfaction of students and parents who are educational demanders, and to suggest practical and policy alternatives to improve school satisfaction. For this purpose, 1,242 elementary, middle and high school students in Seoul and 1,023 parents were tested through analysis of t-test, and regression. Three main results were derived. First, extracurricular activities had a statistically significant effect on school satisfaction. Second, in general, parents in Korea are expected to emphasize the entrance examination-oriented curriculum with a high degree of education, but the higher the extracurricular activities of students and parents, the higher the school satisfaction. Third, there was a difference in school satisfaction by education class, but the higher the education level, the lower the school satisfaction was. It can be seen that extracurricular activities are needed to increase the educational satisfaction of students and parents who are educational demanders. In addition, it is necessary to reinforce the extracurricular activities to the high school which is the upper grade school now.

This research investigated the eating out and snack intakes situation of five hundred eighty five $5^{th}\;and\;6^{th}$ graders living in the city and rural parts of Jeonbuk province. The results of this study are as followed: Nuclear families in urban area and rural community are 84.5% and 64.7% respectively. On the other hand, extended families are 7.9% in urban area and 18% in rural communities. Out of all the households, 34.3% (urban: 37.2%, rural community: 31.5%) answered they like to eat out. Over 50.3% preferred eating Korean style food and the reason was 'the taste': urban (71.4%) and rural community (67.8%). People living in urban communities seemed to eat out more frequently than rural places and $3{\sim}4$ times a month was the average. Usually people seemed to eat out during the weekends and in the evening time 84.3% (after 7:00 p.m.). Based on each family's living standard, people answered 'we hardly ever eat out' for those in the lower class (59.1%), the middle class said once or twice a week (47.1%), and the upper class (35.7%). It was obvious that people in the middle and upper class tend to eat out more frequently than those in the lower class. The most common period of time which snacks were taken was after school (38.5%), on the way back from educational institute (35.0%) and the choices of snacks which they purchased were frozen sweets (56.4%)chips & cookies (25.2%) beverages (9.9%) Fast foods (4.6%) and fried foods (3.9%) in order. Urban children seem to eat more frozen sweets and rural children ate more chips & cookies. Also, amount of snacks between meals showed a higher percentage to those who had more pocket money, The type of snacks were fruits (37.1%) chips and cookies et cetera (19.2%) instant foods (12.8%) dairy products (11.1%) confectionary (10.3%) fried foods (5.1%) in order. The result shows that urban children eat out more frequently than those in rural areas, Eating around 7:00 p.m. was most common and the middle and upper class tend to eat out more frequently than those in the lower class, Also, snacks were most often bought before and after school. After 10:00 p.m frozen goods and chips were the most preferred choice. Specially, the reason for eating fast foods was because of the pleasing taste. From this study, it is clear that eating out and having snacks became pervasive into our lives in both urban and rural areas. Hereafter, an appropriate eating habit should be correctly educated to elementary students by spoken words and textbooks in a curriculum. In reality, snacks are classified as being the leading factor of obesity. Therefore more products containing balanced nutrition should newly develop rather than snacks with high fat content.

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.

Purpose: This study aimed to assess the reference values and factors influencing blood lead levels among Korean adolescents. Methods: The study population consisted of 1,585 adolescents (801 males, 784 females; aged 10-19 years) who participated in the Korea National Health and Nutrition Examination Survey 2010-2013. We analyzed blood lead concentrations in relation to demographic/lifestyle characteristics for all participants. "Reference values" of blood lead levels were calculated as the upper limit of the 95% confidence interval of the 95th percentile. Results: The average "reference value" for blood lead concentrations among Korean adolescents was $2.25{\mu}g/dL$ ($2.49{\mu}g/dL$ for males, $2.07{\mu}g/dL$ for females), and the geometric mean of the blood lead concentrations was $1.34{\mu}g/dL$. Males had higher blood lead concentrations than females (male, $1.48{\mu}g/dL$; female, $1.19{\mu}g/dL$; P<0.001). Elementary school students had higher blood lead concentrations than junior and senior high school students ($1.44{\mu}g/dL$ vs. $1.31{\mu}g/dL$, P<0.001). Participants living in detached houses had higher blood lead concentrations than those living in apartments (P<0.001) and current smokers had higher concentrations than nonsmokers or participants with secondhand smoke exposure (P<0.05). Additionally, participants with excessive alcohol consumption had higher levels than non-drinkers (P<0.001). Conclusion: This study provides national reference data on blood lead concentrations stratified by demographic and lifestyle factors among Korean adolescents. Further studies are needed to elucidate the relationship between increased lead exposure and demographic factors including type of housing.

The purpose of this study is to identify the types of essential inquiry activities presented in elementary science textbooks for grades 5-6, and to find out what difficulties teachers have in the actual teaching process. To this end, the essential research activities presented in the textbook were analyzed into six types: experimentation/observation, investigation/discussion and presentation, data interpretation, discussion/discussion, simulation activity, and expression. In addition, 108 elementary school teachers were investigated for the suitability of inquiry activity achievement standards, suitability at the student's level, student interest, and difficulty in teaching instruction. To summarize the research results, the most frequently suggested type was the experiment/observation type, followed by simulation activity type and data interpretation type. It was analyzed that there was no discussion/discussion type in the 5th grade textbooks, and the 6th graders did not present research activities that correspond to the research/discussion/presentation type and the expression type in the textbook. In the results of teachers' responses to the suitability of achievement standards for inquiry activities presented in textbooks and the suitability of the student's level, 5th graders showed lower average scores than 6th graders, and showed similar average scores in student interest and instructional difficulty. Also, it was confirmed that improvement was required for a total of 17 inquiry activities. Specifically, teachers responded that they had difficulty in guiding inquiry activities when the experimental results did not appear as intended in the textbook, when students' interest in inquiry activities was low, and when students and teachers had low understanding of related science concepts. Teachers pointed out practical problems such as difficulties in long-term observation in astronomy-related units, and students in upper elementary school not actively participating in dynamic play activities.

This thesis examines the play education method shown in the elementary school textbook 'Enjoy Play'. If the educational methods of the curriculum other than plays were presented in the order of 'Understanding play - Appreciation of Works - Creation of Works', the method of drama education is presented sequentially in the order of 'Understanding play - Creation of Works - Appreciation of Works' in the order of 'Understanding play - Artwork - Appreciation' have. Even if such a curriculum considers the study linked to the subject of 'Plays', students may not feel the 'burden' of 'creation', and by simplifying the understanding of 'spoken language', it is rather the characteristic of 'Korean language'. It may also make it difficult for students to feel the attraction. In addition, empathy through the conflict situation of the play or comparison with the actual conflict is mainly presented through the translation of foreign works or the expression of a fairy tale and fantastic world that is far from reality, so the burden of inferring the right life problems can be confirmed. Theatrical expressions and plays and plays learned through textbooks are partially different depending on the educational goals to be achieved. The result of this study is that the course of textbooks for elementary and upper grades may correspond to the problem of expressing 'Plays', but it is regrettable in leading students to think about ways to solve life problems in detail through 'Plays'. It is also necessary to emphasize the importance of expression that makes students realize how to express themselves autonomously in the way of expressing their feelings, but on the other hand, on the other hand, it is necessary to share empathy with feelings first, understand these feelings, Therefore, it was suggested that training to infer expressions and emotions by learning individual expressions through methods of expressing emotions and a process of educating students to voluntarily accept shared emotions are also necessary. Sharing and expressing emotional emotions through 'play', and participation through cooperation and division of labor through the process of performing.

Objectives: The purpose of the study was to investigate the cumulative dental caries rate of pit and fissure sealant in community public health program from 2005 to 2008 follow-up. Methods: The subjects were 4,768 students of 34 elementary schools in Gimcheon. The survey included direct oral examination and cumulative retention rate of pit and fissure sealant from 2005 to 2008. Data were analyzed using PASW statistical package version 18.0 and the level of significance was set at p<0.05. Results: The cumulative retention rate of sealant was 18%, 25%, and 33% after 1 year, 2 years, and 3 years, respectively. In addition, the cumulative retention rate of lower teeth was higher than that of upper teeth. Cumulative dental caries rate increased in sealed group and no sealed group. The cumulative dental caries rate decreased owing to tooth brushing frequency in sealed group and no sealed group. Conclusions: Regular and timely tooth brushing can maintain good oral health condition after tooth sealing. The school based oral health education can prevent loss of sealant and secondary caries.

This purpose of this study was to analyze the variables associated with the ethical consumption behavior of children consumers. This subjects were 431 elementary school students. PASW 18.0 was used for data processing to do frequency analysis, T-test, one-way ANOVA, correlation analysis and multiple regression analysis. The results were as follows. First, children consumers tend to a little higher everyday ethical consumption behavior than others-oriented ethical consumption behavior. Second, as a result of analyzing ethical consumption behavior according to social economic variables, a high tendency of ethical consumption behavior was shown in groups that personality is extrovert and their household economic status is over upper middle class and father's age is higher. Third, the variables affecting ethical consumption behavior of children consumers were self-regulation ability, materialism, altruism, personality tendency, household economic status. Materialism had a negative effect but self-regulation ability, materialism, altruism, personality tendency, and household economic status had a positive effect.

The purpose of this study is to investigate students decision-making progress through ill-structured problem solving process. For this study, 25 fifth graders in an elementary school were observed by applying ABCDE model (Analyze - Browse - Create - Decision making - Evaluate), and analyzed their decision-making progress analyzing framework which follows 3 steps - making their own decision, discussing/revising with peers, and lastly decision making/solving problem. Upper two groups with better performance in ill-structured problem solving model among 6 groups showed active discussion in group and decision making process with 3 steps (making their own decision, discussing/revising with peers). Even though their decisions are not good-fit to mathematical reasoning result, development and application of ill-structured problems would bring better ability of high level thinking and problem solving to students.
