The aim of this research is to see if there are any relationships between reading disposition, career attitude maturity and self-leading learning trait among gifted and general elementary school students. The research results show that: in reading disposition, gifted students showed higher result compared to the general students at reading interest and reading experience, but were not different in reading environment. Also, gifted students showed higher results in career attitude maturity in determination, purposes, assurance, but were not different in readiness and independence. Additionally, gifted students showed higher results at self-directed learning in 8 sub-categories, which are openness to learning, self notion, taking-initiative ability, responsibility, learning zeal, future-oriented self-knowledge, creativity, and self assessment. In addition, the research indicates that career attitude maturity is correlated with reading interest, reading experience and reading environment. Also, self-leading learning is correlated with reading interest, reading experience and reading environment. On the basis of this research, the following are suggested. The research was conducted for elementary school students in 4th~6th grades. Hence, the research needs to be extended to middle school and high school students. And, in order to guide students' careers and improve students' self-leading learning ability, those results need to be applied to real educational situations. In addition, research need to be done to find out what kind of books have more effect on career attitude maturity and self-directed learning trait.

Objectives: Blood mercury levels among adults living in certain areas of the Gyeongsang Provinces have been shown to be very high (Kunwee County $29.6{\mu}g/L$, Yeongcheon-city $26.7{\mu}g/L$). The purpose of this project was to determine mercury exposure levels in schoolchildren and factors related with their mercury levels in high mercury exposure areas identifyed by the 2007 Korea National Environmental Health Survey. Methods: From June to September 2010, 1,097 students from grades 3 to 6 at 19 elementary schools participated in this study, including 294 students from 10 elementary schools in Kunwee County, 529 students from Yeongcheon City, 122 students from two elementary schools in Pohang City, North Gyeongsang Province, and 152 students from two elementary schools in Ulsan Metropolitan City. Biological samples from schoolchildren, including whole blood, urine and hair, were collected to measure total mercury at the time of a health check up. Information about children was collected by questionnaire. Total mercury concentrations in blood were measured using the Direct Mercury Analyzer 80 with the gold-amalgam collection method. Results: The mean mercury levels were $2.70{\mu}g/L$ in 1,091 blood samples, $2.25{\mu}g/g-creat.$ in 820 urine samples and $1.03{\mu}g/g$ in 1,064 hair samples. Blood mercury levels in the schoolchildren was slightly higher than the result of $2.4{\mu}g/L$ from a 2006 survey of elementary school children on exposure and health effects of mercury by the National Institute of Environmental Research. However, 0.3% and 4.5% of participants exceeded the reference level of blood mercury by CHBMII ($15{\mu}g/L$) and the US EPA ($5.8{\mu}g/L$), respectively. The reference level of urine by CHBMII ($20{\mu}g/L$) was exceeded by 0.4% of participants. As factors, residence period in the study areas, residence type, father's education level and income all showed significant associations with mercury level in the biological samples. The number of dental amalgam sides showed an association with urine mercury. Fish intake preference and fish intake frequency were important factors in mercury levels. In particular, intake of shark meat and recent intake of shark meat were associated with higher mercury levels. In this regard, participation in the performance of an ancestral rite showed a relation with higher mercury levels. Conclusion: The intake of shark meat was very important factor to high mercury exposure level. It is recommended to monitor and manage students with high mercury exposures who exceeded CHBM II and EPA guidelines, and include blood mercury testing in the Children's Health check up for this province.

This study was conducted to investigate the elementary school students' consciousness of safety, activities to prevent their accidents and factors causing such accidents. For this aim, a research was conducted from Nov. 19 through Dec. 22, 2007 by means of questionnaires distributed to 800 students enrolled in the 5th and 6th grades of 4 elementary schools in a urban-rural combined city. Out of the questionnaires distributed, 785 were collected and put to analysis by using SPSS 13.0 program to determine t-test, ANOVA, logistic regression, etc. 1. The maximum scores of safety consciousness revealing relatively high level of safety consciousness. There was, however, statistically significant difference by grade, type of residence, school life and academic achievements. In detail, 5th graders featured higher level of safety consciousness and those who live in apartments, lead a pleasant life at school and get better academic scores tended to keep higher level of safety consciousness. 2. The subjects of the high scored of activities to prevent accidents, with a statistically significant difference by gender, grade and individual personality. Females, 5th graders and active students were found to be more conscious of preventive activities for accidents. 3. In general, 6th graders and active students turned out to have experienced more accidents. 4. The main factors exerting influence on occurrence of accidents on the part of elementary school students are known to be preventive actions and consciousness of traffic safety in the category of safety consciousness. The significant variable in preventive actions was preventive actions of traffic accidents, burns and intoxication by category of accidents, but individual personality by category of general characters. Sixth graders and male students experienced more accidents, without significantly significant difference, though. As a result, From the above findings, prevention of safety accidents is found to be very important for elementary school students. It is therefore suggested that schools as well as homes should continue to conduct practical education to prevent accidents with priority placed on familiarizing students with preventive activities in daily life in consideration of their personal characters.

The aim of this study is to analyze the impact of step-by-step educational comic book behavior of the elementary school students and their reading levels on their learning competencies. To this end, qualitative research with focus group and deep interviews was conducted with students on different reading levels. During their repetitive reading activities, the students tended to use various educational comics within the same subjects area on their corresponding reading levels. Such behavior led the students to further read other books than comics in the similar subjects areas, and by doing so, the books acted as an important reference to the students' class materials. It was found that the students' such behavior has positive impact on the improvement of their learning competencies. It is hoped that this study will be supportive to develop self-study methods and effective reading guidance plans by improving the usage of educational comics.

Purpose: The aim of this study was to develop a self-control competency scale for school-aged children and to confirm its reliability and validity. Methods: This study involved methodological research to verify the reliability and validity of a self-control competency scale for school-aged children. Data were collected from 438 students in the fifth and sixth grades of elementary school. Results: The self-control competency scale was composed of 13 items and six subscales (control of relationship with one's teacher, problem-solving, peer empathy, control of relationships with one's peers, impulse control, and emotional control). The internal consistency reliability of the scale was evaluated using Cronbach's α, which was .83 for the entire scale and ranged from .65 to .76 for the subscales. The model of six subscales was validated by CFA (CMIN/df=1.977; p<.001, GFI=.94, SRMR=.050, RMSEA=.065, IFI=.95, TLI=.93, CFI=.95). Concurrent validity was evaluated by comparing this scale to the scale developed by Nam and Ok (2000), and a significant correlation was found (r=.82, p<.001). On this scale, higher scores indicate higher levels of self-control among late-school-aged children. Conclusion: This scale can be used as a valid and reliable instrument for examining self-control competency among late-school-aged children.

The purpose of this study was to provide and analyze the fundamental data on leadership skills and to analyze leadership skills among giftd elementary students according to grade, subject and gender. The main research questions in order to achieve the purpose of research are as follow. First, are there any differences of gifted elementary students' leadership skills in gifted groups? Second, do leadership program have an effect on improvement of gifted elementary students' leadership skills? The subjects for this study were 488 gifted elementary in 4th-6th grade in Busan. The students in the experiential group went thought 16 session do leadership program. After that, they had pre-tests and post-tests. the devices used to verify the effectiveness of the program were leadership skill scales. For this research analysis, MANOVA was used to investigate the first research questions and MANCOVA was used to investigate the second research question. Results from this study are as follows. Firstly, students in higher grades received fewer leadership skills points. This fact suggests that the leadership programs from the fourth grade should be implemented in 5th and 6th grade gifted education as well. Secondly, in the analysis of the results from gifted mathematics and gifted science, little significant statistical difference was shown. Thirdly, the analysis of leadership skills according to gender showed statistical significance. Finally, the study showed that the leadership education program had a positive effect. So the gifted 4th, 5th, and 6th grade students improve their leadership skills points by the end of the 16 week programs. Consequently, it is suggested that leadership education program on gifted elementary education was significant to improvement of leadership skills.

This study discussed the climbing learning method which studied and practiced by Professor Saito Noboru. This is the learning method which is devised to know not only the relationship of the learning factors but the systemic or structural connection of whole studying contents- affects children's math learning ability through practical class to both the lower and the higher grades. To achieve the purpose of this study, these following issues were set; A. Develop the teaching and learning course of mathematics by applying the climbing learning method. B. Execute the mathematics lesson according to the climbing learning method and analyze the learning achievement. C. Analyze the difference between application of the climbing learning method and that of the learning method by student's level in mathematics. D. Analyze what the climbing learning method gives a shift of the recognition of learning mathematics. In order to accomplish these study issues, we analyzed the text book of math not only for children but also for teachers and developed the teaching and learning course applied the climbing learning method with advice of experts. It was chosen two different homogeneous groups each, third year for lower grade group and fifth year for higher grade group. It was done the experimental group lesson applying the climbing learning method and general lesson for the control group. After then, t-test against independent samples was done depending on the result of the student's assessment(T1, T2). These two groups' students were divided into smaller groups based on result of achievement level regardless of gender. These subgroups were confirmed the difference of learning ability between upper and lower level group. As regarding the result making out grades of faith and attitude for math, t-test was used on independent sample. At the same time, experimental groups were tested using learning attitude with the learning structure chart. Through this study the following results are obtained and the conclusion was drawn. Firstly, although applying the climbing learning method to the lesson does not have significant effect to the lower grade of elementary school student's achievement it has significant influence on the higher grade student's achievement. Second, as a result of analyzing the difference between the climbing learning method and the learning method by student's level in mathematics, it is of no beneficial effect to the lower grade both upper level and lower level. However, it has appreciable effect to the higher grade classes both upper level and low level. Especially, upper level students have higher effect than low level students. Third, climbing learning method does not affect to the faith and attitude of the lower grade students positively, but it has affirmative effect to the higher grade students'. As a result of the survey of the experimental groups which were applied to the climbing loaming method, the lesson by using the learning structure chart proved to be helpful to the both the lower and higher grade. The best advantage of using the learning structure chart, children say, is easily understood whole contents of studying and is useful for review. Furthermore, using the learning structure chart is more efficient compared with previous learning method and is given the successful result to self-directed learning. In conclusion, keeping up with the current of the thought of education, we suggest a scheme as a new teaching method from the constructive learning method which emphasize the self-directed learning.

The purpose of this research is to investigate and analyze the attitudes and images of middle school students toward invention. This aims to provide basic data on qualitative improvement invention education. The results of this research are as follows: First, as for middle school students, the level of emotion and interest attitude toward invention is higher than elementary school students. The image of invention is positive but difficult (M=3.70). Second, as the overall attitude to invention according to gender of middle school students shows a consistent invention attitude, the attitude formation on invention during elementary school time is found to be important. The overall image of invention according to gender is shown to be significantly different (p<0.05). Third, the overall attitude on invention according to the grade of middle school students does not show a statistically significant difference (p>0.05). As for the ranking according to factors on attitude depending on grades, cognitive attitude is followed by emotional attitude, attitude of interest, and practical attitude. The overall image of invention according to the grade of middle school students does not show a statistically significant difference (p>0.05). This is determined as a result of the large pressure acting on the study from middle school. Finally, the acts of invention such as idea, creation, imagination, creativity are considered as important as the results of analysis of the words of the invention. Invention is analyzed to contribute to developing new products, providing convenience in life, social development, usefulness in real life, and alleviating inconvenience.
