This study was conducted in order to provide basic study material for children's garment design. The subjects of this study are fifth and sixth grade elementary school girls, who demonstrate rapid growth and the differences among individual somatic types are apparent. Their bodies are studied, categorized into patterns and the characteristics are examined. 1 The increase of height and length measurements according to age increase are much larger than that of breadth, depth and girth menasurments. 2. Eight factors are drawn upon factor analysis and the rate of factors comprisedare 78.68%. 3. The shapes of lower body of higher grades girls in elementary school are classified into three categories. The first type is slender in lower body and the second type is more contoured around waist area with longer length and higher height than the average elementary school girls. The third type is heavy in the lower body. 4. Eighteen items important for somatic categorization are selected through stepwise discriminant analysis and the exactitude rate of these items is 93.3%.

There are concerns that the recent surge in multicultural families and the continuation of non-face-to-face education, such as remote classes caused by COVID-19, are causing educational gaps among lower grades in elementary school. In particular, the importance of reading, writing and listening to our language should be established in lower grades of elementary school. Therefore, the research has recently developed contents that can enhance understanding by utilizing highly interested artificial intelligence tools and provide interesting Korean language education through play. In the future, there will be various attempts for artificial intelligence tools to be used in lower-grade elementary school education.

This study was about to investigate the characteristics of elementary school students' feet growth, comparing and analyzed the measured values and the index values of 3D scan data. As the results from analyzing the measured values, the all measurement items excluding 'Toe 5 angle' showed some significant differences among the age classes, knowing that the elementary school students' feet were continually grown. Although, the items of length, thickness, width, height and circumference indicate some rapid growth of feet at 11 years old, but it appears slowing growth of 'Foot width' after the age of 11 years old. The angle item didn't show any sequential differences according to ages. As the results from analyzing the index values, the children in higher grades have longer 'Toe 5', thicker ankles, wider and thicker the superior part of feet than the children in lower grades. For the superior and the middle part of feet were lowly raised, their Arch height was low and thick. The inferior part of feet showed narrow width and higher height. Giving that the Medial ball width was wide and the Toe 1 angle is high for the children in higher grades, it is expected that the Metatarsophalangeal I might be more projected than that of children in lower grades. Likewise, knowing that the male students' feet shape was bigger than female students' feet from the result that the male students' index values were higher.

The purposes of this study were to 1) examine the dietary patterns of fatty acids and the fatty acid composition in serum, 2) determine selenium (Se) concentrations, and 3) investigate how serum fatty acid compositon affects serum levels of Se in Korean elementary school children. The subjects consisted of 168 school children(82 boys & 86 girls) belonging to 1st through 6th grades, and their dietary assessment was evaluated. The serum fatty acid composition was analyzed by GLC, and the ICP/MS method was employed to measure serum Se concentration. Total average intake of PUFA, MUFA and SFA were 10.5g, 12.7g, 11.2g respectively. Total average dietary P/M/S ratio was 1.10/1.18/1.0. The average intake of $\omega$3 fatty acids and $\omega$6 fatty acids were 1.33g, 9.19g, respectively. The $\omega$6/$\omega$3ratio was 14.2 which is higher than the recommended range. In serum fatty acid composition, PUFA, MUFA, SFA were 40.6%, 28.1% and 31.6% respectively. The average $\omega$3 fatty acid composition was 3.80%, and the mean value of $\omega$6 series was 36.8%. The M/S ratio of girls was significantly higher than boy's in fatty acids intake and in serum composition. Mean Se concentration of total subjects was 416.7ug/l and it was significantly higher in the lower grades(1st-3rd)than in the upper grades(4th~6th, p<0.05). Although the mean serum Se concentration was negatively correlated with PUFA composition in total boys and girls, it was not significant. Serum Se concentration was negatively correlated with P/S ratio and C24:1 concentration(p<0.05). In addition, serum composition of $\omega$6 PUFA and C24:1 showed negative correlations with serum Se in only lower grades girl(1st~3rd), and further studies are needed to clarify in these phenomena. In conclusion, the mean serum Se concentration was significantly lower in upper grades (4th~6th)than in lower grades(1st~3rd) of elementary school children and was negatively correlated with P/S ratio of serum fatty acids. More detailed studies on relationship between Se and fatty acids are required.

The purpose of this study is to analyze the differences of food habits and food preferences between lower and higher grade students through the survey of elementary school students in Daejeon four elementary schools located in Jung-Gu and Seo-Gu in Daejeon are selected for this survey randomly and the completion of the questionnaires are according to grade. 1. Practical Analysis of Food Habits: For regular meals, the highest number of subjects skipped breakfast. It is being found that the girl students (81.61%) consumed more cooked rice than the boys (78.85%) and more boys (13.10%) ate bread or milk more than the girls (9.20%). The most important thing for the lower grades students (34.20%) when consuming is the nutritious foods, while the higher grades students (49.67%) consumed the set meals. During consumption, the highest number of the subjects watched TV or read books from time to time. More higher grades students (38.98%) preferred spicy and salty foods than the lower grades (22.09%). 2. Food Preferences: Between rice and noodles, most subjects preferred cooked rice (81.38%), Jajangmyeon (80.80%), Ramyeon (79.43%), and disliked bean-mixed rice (28.39%). For soups, Most students enjoy the Deokkguk. Majority of the subjects prefer meat and fried or steamed foods, and also grilled and pan-fried dishes. For the pan-roasted and fried dishes, most subjects did not enjoy the rhizome fry and sweet-pumpkin fry methods, and for vegetables, they did not like wild vegetable and seasoned cucumber (40.57%) The higher grades students enjoy the vegetables and salads more than the lower grades students. For Kimchi varieties, it is found that subjects like the cabbage Kimchi (69.66%) the most.

This study explored mothers' and grandmothers' perception regarding child rearing practices as overprotective behaviors for first to third grade levels of elementary school. The study was conducted on 202 mothers and grandmothers of first to third grade elementary school students. Questionnaires were made with 40 questions on overprotection behaviors selected from the existing questions for preschooler, high grade elementary students, and youth. The questionnaires were distributed to target subjects to answer how they would perceive when each of question is applied to their lower grade elementary students. Based on the collected responses and the factor analysis, it was found out that the overprotective behaviors were classified into four factors such as "reduction in independence," "over-sensitiveness to safety," "interference in daily life," and "health anxiety." There were significant differences in the perception of the overprotective behavior by the subjects depending on the generations, features of children and mothers. This study focused on the lower grade elementary school students who have been removed from studies due to the lack of intervention measures. It has the implication in that the findings of the study can give the basic data for the development of the scale on overprotective behaviors in lower grade elementary school students.

Purpose: The purpose of this study was to identify the relation between personality traits and awareness of gender equality. Method: A descriptive survey design was used and 688 students in fifth and sixth grades in 3 elementary schools were selected as participants. Result: 1. Level of gender equality awareness among the students was 2.82. This is higher than average and was most influenced by awareness of family life, followed by awareness in education, work environment and social-cultural life. 2. Students with higher levels of extraversion-introversion had higher levels of awareness of gender equality in family life, work environment, and education. Students with higher levels of tough-mindedness showed lower levels of gender equality awareness in family life and work environment, while those with higher levels of lying showed lower levels of gender equality awareness in social-cultural life. Conclusion: Personality traits and awareness of gender equality were correlated to some degree. However, in order to understand the characteristics of childhood personality traits and the behaviors of our children though the mediation of the gender equality awareness as society changes, and to let them grow with understanding of gender equality, it is essential to implement various kinds of education in families, schools, and the society.

In Korea, the lower elementary grades are applying a topic-oriented integrated curriculum. It causes a lack of science content and inquiry experience for young children. The purpose of this study is to understand the scientific experiences and perceptions of the lower elementary graders and to inquire about the meaning of those experiences in their science learning. Four students (male 2, female 2), their parents, and their first-year homeroom teachers participated in the study. The data collection was mainly conducted through in-depth interview of them. Results showed that the 'experiments' were the student's the main perception of science, and the epistemic emotion that students mainly feel about science was 'curiousness'. Since most experiences were dependent on non-formal educational experience, the parents were an important factor to determine their experiences about science. Various factors, such as students' scientific experiences, their epistemic emotions, and the parents, interacted to form children's perception of science. The positive perception of science affected the level of motivation and expectation for science learning as the third grade. It is suggested that improvement of curriculum and textbooks should emphasize scientific exploration for the lower graders of elementary school, which provides them meaningful scientific experience in school.
