The purpose of this study was to evaluate the elementary students' knowledge, attitudes, and practice for food hygiene and safety. A self-administered questionnaire was developed and offered to 375 elementary school students throughout the Seoul region. The results of the survey were as follows: First, the knowledge, attitudes, and practice were not at satisfactory level. The scores of children's knowledge, attitudes, and practice were 67.42%, 3.83, and 3.81 out of 5 point scale, respectively. Second, knowledge, attitudes and practice levels were significantly different according to demographic characteristics. The lower grade-students had significantly higher scores for knowledge (p<.05), attitudes (p<.05) and practice (p<.01) than higher gradestudents, suggesting that food hygiene and safety education is more effective in younger students or that repeated education is needed for higher grade-students. Third, knowledge, attitudes and practice levels were significantly correlated each other. These results suggest that the education programs for food hygiene and safety should be developed for, as well as implemented in, lower elementary school grades.

The purposes of this study were to provide the fundamental data on elementary school girls' somatotype for their clothing construction by contemplating the stage of physical growth dividing into the period of school age and characterizing the variation of body type according to the school age. The results are as follows : 1. Form the results of one-way variables analysis and multiple comparson test(Duncan's test) classification of the period school age can be divided into 'early grade(1 2 grade)' ' middle grade(3 4 grade)' and 'later grade(5 6 grade)' 2. As the results of analyzing Mean Coefficient of Variation and Standard Deviation graph for direct and indirect measurments and index especially of the Coefficient Variation that explain individual difference of growth the items of height indicates individual difference related with height of lower body of early grade group the items of length individual difference related with length of upper body of later grade group and the items of circumference make little difference. The items of anagle makes pretty higher value that direct measurements and especially in lower angle of chest make a distinctive difference, This fact proves that children's somatotype change from the belly part extruded forwards of early and middle grade to the upper body part slanted slightly forward of later grade.

This study researches an obesity index and the realities of physical activity of elementary school children and provide basic data to instruct correct physical activity for low weight and obese children. The subject was 813 Elementary School Children of grade 4-6 in Kyungju and data were collected with a Physical Activity Questionnaire from YHS, USA. The collected data were analyzed with real number, percentage, average and standard deviation techniques. The range was by SPSS WIN. Both of them were in the normal range, between -38.3 and 77.7, between low weight and obesity. The results are as follows : 1. An Obesity index according to grade and sex: the average obesity index of 423 boys was $7.56{\pm}15.7$, for girls it was $2.56{\pm}14.3$. Both of them were in the normal range, between -38.3 and 77.7. There were low weight($-38.85{\pm}0.9$) students as well as obese, including extremely low weight children ($-38.85{\pm}0.9$) and extremely obese children. 2. On the whole, in the Frequency of the 25 item physical activities breakdown, children reported to watch TV 1. ($2.7{\pm}0.6$), or do homework($2.1{\pm}0.9$), more than three-fourths of the week, male children, however, played more football($2.0{\pm}0.9$). As male obese children do less MET5, MET8(highly active activity) than male normal children, it was also discovered that low weight children do more severe activity in MET8(high activity). In female cases, it was revealed that neither do highly intense activity. 3. In physical activity, male children received higher points than female children with $92.94{\pm}37.95$ to $74.46{\pm}29.50$. On the whole, male and female obese children had lower score than normal children. 4. As for attitude toward physical activity, male children($31.96{\pm}4.37$) had a positive attitude than female children ($29.57{\pm}3.89$), but obese male children had a negative attitude regarding activity viewed as normal. Therefore, in preventing obesity in elementary school children the treating of under-weight children should be included in the obesity program so as to prevent mal-nutrition or deficiency. It is needed to instruct obese children to carry out intensive work-outs at least 3 times a week through systematic programs. It is also needed that parents and teachers educate elementary school children from an early age with information on the frequency and intensity of work-outs to prevent obesity. It is also desirable that children be educated to carry out physical activities that address their specific needs. As a result of this study, obesity management must be started from elementary school and children should be instructed to act in high-intensity actirities when they spend leisure time.

Purpose: The purpose of this study was to examine the sexual maturation, body image, and self-esteem of Korean elementary school girls with symptoms of precocious puberty compared to those with no symptoms of precocious puberty. Methods: The subjects were 309 girls of lower grades in elementary school. Tanner's Sexual Maturation Rating (SMR), Self Image Scale, and Self-esteem Scale were utilized to determine the presence of symptoms of precocious puberty, body image, and self esteem. Collected data were analyzed by Chi-square test, independent t-test, and one-way ANOVA using the SPSS/WIN 17.0 program. Results: The percentage of the girls with breast development was 14.9%. Breast development usually began in the third grade (56.5%). Of the subjects, 0.3% were experiencing menstruation. Breast development was related to grade, age, height, weight, and a cause of worry. There was a significant difference of body image between girls with breast development in the first grade and in the second grade. Conclusion: An effective intervention that can improve the self-image of children with symptoms of precocious puberty should be developed to prevent and treat physical and mental problems related to sexual maturation.

To compare Na intake and excretion in elementary school children in rural and urban areas of Korea, dietary intake record, urinary Na and K excretion and preference for salty taste were measured in 39 children in 4th grade in Seoul and 36 children in 4th and 5the grades in Kochang-gun)farming area) and their mothers. mean daily urinary Na excretions were 48.8mEq in children and 62.3mEq in mothers. Mothers showed significantly higher preference for salty taste compared to children(X2=16.09, p<0.01). Among the children, those in Seoul had higher preference for salty taste than those in Kochang-gun(X2=8.32, p<0.05). Since the children showed significantly lower preference for salty taste than mothers, more researches and efforts should be directed to prevent the shifts of the taste of the children in order to decrease their Na intake and the risk of hypertension later in life.

The purpose of this study was to investigate differences of food preference and nutrient intake of students between elementary school and middle school in the same area and to provide data for better school food service. The subjects were 486 students, third to sixth grade of 3 elementary schools and first to second grade of 1 middle school in Nam jeju gun, Jeju, and the survey was conducted during June 1999. Food preference was assessed using questionnaires and 24-hour food intake was assessed using dietary record method. Data of weight and height were obtained from annual physical examination conducted at schools in May 1999. All the variables were compared among 3 groups in each gender: third and fourth grade elementary school(ES3,4), fifth and sixth grade elementary school(ES5,6), and first and second grade middle school(MS1,2). The results were summarized as follows. The average height, weight and BMI for the 3th grade boys in elementary schools met the national averages, but those of the others are below the national averages. Although general pattern of food preference looked similar among groups, food preference scores were significantly different among groups in 38 kinds foods for boys, and 27 kinds of foods for girls. MS1,2 group showed significantly lower food preference scores for most of foods as compared to those of ES3,4 and ES5,6 in both genders. Students of higher grade took more starch foods such as instant noodle, stewed rice cake and snacks. Average energy intakes of all the groups except MS1,2 girls were lower than recommended dietary allowances(RDA), and average intakes of protein, vitamins B1 and C met RDA, but the other nutrients were taken less than RDA and especially the intakes of iron, calcium and vitamins B2 were poor. Most of nutrients taken by school food service meal provided a major proportion of intakes. In conclusion, students of middle school were more particular about their foods served at school food service and marked lower food preference score than elementary school children and more conscious about their weight and appearance. These points should be reflected in planning food service menu at middle school.

Purpose: The purpose of this study was to investigate predictors of behavior problems of military children in elementary school. Methods: Participants were 195 military children who were attending D-elementary school in C-city. Data were collected from July 8 to July 10, 2013, using self-report questionnaires which included Han's Externalized Behavior Problems Scale, Lee's Parent's Rearing Attitude Scale, and Hong's Friend/Teacher Support Appraisal Scale. Data analysis was performed using the SPSS/WIN 18.0 program, which included the t-test, the one-way ANOVA, Pearson correlation coefficients, and the multiple liner regression analysis. Results: The mean score of the subjects' behavior problem was 1.47/5.0 points. The degree of the score is similar to or slightly lower than that of ordinary children. There were statistically significant differences in behavior problems according to gender, grade, birth order and economic status. Behavior problems have a negative correlation with parent's rearing attitude, parent-child relationship, teacher's support, and friend's support. Influencing factors of behavior problems were teacher's support, father-child relationship, and mother's rearing attitude, which explained 20.6% of the variance. Conclusion: The finding of this study suggests there is a need to increase teacher's support for elementary students and to educate parents to improve their parenting skills by developing proper school health programs.

Objectives : The aim of this study was to assess the effect of air pollution on the daily respiratory symptoms of elementary school children in Seoul. Methods : Using the panel study design, we collected diary data for the children's respiratory symptoms during the 1st day$\sim$15th day of April, July, October and December in 2003 among the 2nd and 3rd grade elementary school students. We merged the respiratory symptom data with the ambient air pollution data that was monitored by Ministry of Environment. Using a generalized estimate equation, we evaluated the relationship between the daily symptoms of the subjects and the exposure to ai r pollution after controlling for various potential confounders. Results : The nitrogen dioxide (NO2) exposure of the current day significantly increased the upper respiratory symptoms (adjusted odds ratio=1.12, 95% CI=1.01-1.24) and the lower respiratory symptoms (adjusted odds ratio=1.18, 95% CI=1.06-1.31) in the elementary school children. The sulfur dioxide (SO2) and carbon monoxide (CO) exposure in the current day was associated with the lower respiratory symptoms (adjusted odds ratio=1.12, 95% CI=1.01-1.25 for SO2; adjusted odds ratio=1.16, 95% CI=1.02-1.32 for CO). Conclusions : We found that exposure to air pollution affects the daily respiratory symptoms in children. This study suggests that the effect on children's health? due to the short term changes in air pollution levels needs to be considered as an important public health problem.

The purpose of this study was to examine the awareness level of the prolonged sound rules in elementary school students. The participants in this study were 148 elementary school students in grades 1 through 6. Their awareness level of the prolonged sound rules was evaluated on reading tasks composed of 40 words and sentences. An one-way ANOVA followed by Scheffe hoc tests showed the showed the statistically significant difference between the groups for the awareness level of prolonged sound rules. The younger the children, the larger differences in the awareness of prolonged sound rules. The awareness might affect their cognitive development and a systematic instruction may be helpful especially in lower graders. In conclusion, the findings of this study showed significant differences in the awareness level of the prolonged sound rules at both words and sentences level. It was also found that as the age of children increases, the awareness level of the prolonged sound rules tends to increase which appeared to be completed by the 3rd grade.
