This study was done to determine the factors associated with childhood overweight in 721 sixth grade elementary school students, in Busan. The students' heights, weights, waist circumferences and triceps-skinfold thicknesses were measured using standard techniques. Other data were collected using a questionnaire that included information about physical activity, television watching, and the amount of exorcise taken during leisure times, family history of diseases related to obesity: social data including family income, parents'education and occupations, eating behaviors; parental weights and heights; and parental activity levels. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex. The prevalence of overweight revealed no significant difference between sexes, (24.2% in boys and 22.03% in girls). The risk of childhood overweight was significantly greater if either the mother or the father were overweight. The odds ratio for childhood overweight associated with maternal overweight was 5.045 (94% CI : 3.262-7.801), and 2.727 (95% CI : 1.764-4.218) was the case for parental overweight. Children having a history of hear diseases had higher odds ratios than those who did not. The odds ratios for overweight associated with income were not different. However, a higher odds ratio for overweight was observed in children whose fathers had only an elementary or middle school education than those whore fathers had a high school or college education. Children whose fathers' occupations were service workers or shopkeepers (OR : 3.314, 95% C = 1.851-5.934) or had no occupation (OR = 3.756, 95% CI : 1.898-7.430) had a treater risk of overweight than those whose fathers'were professionals or once workers. The risk of overweight increased in children having more irregular meal times and faster eating times, rather than those having an intake pattern of high energy and sugar containing floods. The amount of exercise taken during leisure times, and daily physical activity showed no difference between overweight and non-overweight children. However, television watching time, especially on weekends, was greater in overweight children than in non-overweight children. Television watching time was positively correlated with BMI, triceps-skin(31d thickness, waist circumference and waist/height ratio. Therefore, television watching was found to be a useful predictor of overweight in children. Television watching in children was negatively related to paternal activity levels, and positively related to parental television watching time. In fact, fathers whose children were overweight were physically less active than fathers whose children were non-overweight. Parents appeared to be a strong influence on their children's physical activity levels. In conclusion, a low family social class, defined on the basis of the father's occupation or education, parental overweight, increased television watching, and unhealthy physical activity levels in parents were all considered risk factors for childhood overweight. Among these, television watching time and lack of physical activity were considered to be the most important risk factors that could be easily modified for the prevention of and intervention in, overweight in children.

The purpose of the study were to analyze the patterns of adolescent suicide attempts, and to explore the effects of personal psychology (subjective depression, subjective stress), health status (BMI, subjective health perception), and subjective academic performance on the types of youth suicide attempts. For this research, data of 'The 15th Korea Youth Risk Behavior Survey' were analyzed employing a hierarchical logistic regression analysis. The findings are as follows. First, out of 1,731 youth suicide attempts 156 (9%) were impulsive and 1,575 (91%) were planned. Girls(67.3%) attempted suicide more than boys (32.5%), and middle school students (62%) attempted suicide more than high school students (38%). Second, the variables that significantly affect suicide attempt types were subjective depression, subjective stress, and subjective health perception, after controlling for gender, grade level, school type, and SES. The rate of planned suicide attempts was higher among those who experienced depression than among those who did not. In the case of subjective stress, adolescents who felt stressed were likely to commit planned suicide attempts. Those who attempted impulsive suicide showed 1.32 times higher subjective health perception scores than those who attempted planned suicide, indicating adolescents who perceived they were not healthy were more likely to attempt planned suicide. BMI and subjective academic performance did not have a significant effect on the types of youth suicide attempts. These findings suggested the necessity of systematic intervention in Home Economics classes or extra-curricular programs, to prevent potential youth suicide attempts.
This study analyzed the difficulties and mathematical modeling knowledge improvement that an elementary school teacher experienced in modifying a mathematics textbook task to a mathematical modeling task. To this end, an elementary school teacher with 10 years of experience participated in teacher-researcher community's repeated discussions and modified the average task in the data and pattern domain of the 5th grade. The results are as followings. First, in the process of task modification, the teacher had difficulties in reflecting reality, setting the appropriate cognitive level of mathematical modeling tasks, and presenting detailed tasks according to the mathematical modeling process. Second, through repeated task modifications, the teacher was able to develop realistic tasks considering the mathematical content knowledge and students' cognitive level, set the cognitive level of the task by adjusting the complexity and openness of the task, and present detailed tasks through thought experiments on students' task-solving process, which shows that teachers' mathematical modeling knowledge, including the concept of mathematical modeling and the characteristics of the mathematical modeling task, has improved. The findings of this study suggest that, in terms of the mathematical modeling teacher education, it is necessary to provide teachers with opportunities to improve their mathematical modeling task development competency through textbook task modification rather than direct provision of mathematical modeling tasks, experience mathematical modeling theory and practice together, and participate in teacher-researcher communities.
The demand for medical care and welfare for patients with disabilities is expanding, and healthcare professionals are also increasingly interested in the need for medical care for patients with disabilities. The purpose of this study was to evaluate the competency of disabled patients' management and the education experience of dental hygiene students, who are the main players of oral health care for disabled patients. A total of 196 students in the dental hygiene department and 3rd and 4th grade students were surveyed using questionnaires. As a result, most of the students had a positive awareness of disabled patients; 84.7% answered with the need to train dental hygienists in specializing in handicapped patients, 76.5% were willing to attend seminars related to disabled patients after graduation, and 71.4% of the students provided dental treatment for patients with disabilities in curriculum and comparative curriculum. The students who provided treatment for disabled patients showed that their competence in most areas of knowledge of disabled patients, oral health education, and oral disease prevention was highly evaluated as significant. The competence of respondents who answered that the theoretical education was sufficient was significantly higher. Based on this, institutional support for the education of dentistry for disabled patients is needed, and sufficient theoretical education and practical training should be offered to foster personnel capable of contributing to the improvement in the oral health of patients with disabilities. In addition, in-depth discussions on the training of dental hygienists specialized in handicapped patients should be conducted.

This study analyzed the vocabulary level in the 'Water' unit of chemistry I textbook. It also analyzed its relevance to the 11th graders' vocabulary level. The main tool for analyzing vocabulary level was SWA(Science Word Analysis) program which was referenced the Standard Korean Dictionary and Graduated Vocabulary of Korean Language Education. The results in this study turned out to be as follows: The distribution of scientific vocabulary level increased from Level-1 to Level-3 and showed a tendency to decrease from Level-3 until Level-5. The average percentage of Out of level is the largest as 37%. The highest percentage of non-scientific vocabulary was Level-1. The distribution of non-scientific vocabulary level decreased progressively. The Level-5 and Out of level are used 18% averagely. So, there are 6 vocabularies of Level-5 and 82 vocabularies of extra-level inappropriate in scientific vocabularies. And there are 53 vocabularies of Level-5 and 145 vocabularies of Out of level inappropriate in non-scientific vocabularies. Therefore, the overall state of textbooks for grade 11 students are reasonable. But there are a great many vocabularies inappropriate for them. Those should be used minimum, and to be changed to the 1-4 of level vocabulary as stated in the student's level of understanding of appropriate vocabulary.

The aim of this study was to investigate the prevention effect of oral disease on the school-based toothbrushing program(SBTBP) in Daejeon in 30 months. The experimental subjects were the 5th grade's 70 students who have gone to school with the school-based toothbrushing program since the 3th-grade. The control school was located in close geographical area with similar economical status. The questionnaire about oral health knowledge and behavior was done by self-recording. After one dentist examined the dental caries and periodontal status, the gingival crevicular fluid(GCF) was collected with #25 paperpoint for 1 miniutes. Matrix Metalloproteinase(MMP)-9 in GCF was analyzed by ELISA. The SBTBP group had the upper oral health knowledge than the control significantly(p<0.001), but, the SBTBP group had no difference of the oral health behavior from the control. Although the SBTBP group had the lower plaque index than the control significantly(p=0.02), the SBTBP group had no difference of the gingival index, calculus index and the concentration of MMP-9 in GCF from the control. In conclusion, The SBTBP had the effect to reduce the dental plaque and to improve the oral health knowledge. On the other hand, the effect to prevent dental caries and periodontal disease of SBTBP was not clear.
This study was conducted to investigate the relationships between dietary habits and food intake and impulsiveness and aggression in the 6th grade students(boys 53, girls 37, N=100) of the elementary school in Chuncheon area. The main results are as follows. According to the survey on dietary habits and foods intake, the score of "I eat a balanced diet that consists of boiled rice, soup, and more than two side dishes" was the highest as $4.31{\pm}0.96$ while the score of "I watch TV or read a book during having a meal." was the lowest as $3.16{\pm}1.36$. The girls had better score than boys for "I eat slowly." while the boys had better score than girls for "I exercise every day."(p<0.01). Total scores of dietary habits were not significantly different between the sexes. For having fruits, girls($4.28{\pm}0.77$) ate them more frequently than boys did($3.81{\pm}1.02$) but for having soda drinks, boys($2.85{\pm}1.10$) drank more frequently than girls did($2.32{\pm}1.11$) (p<0.05). The total scores of impulsiveness were not significantly different between the sexes(boys $2.60{\pm}0.93$ vs. girls $2.57{\pm}0.99$), but those of aggression were significantly different(p<0.05) between the boys($3.01{\pm}0.79$) and the girls($2.63{\pm}0.78$). The score of total dietary habits had a negative relationship with that of aggression(r=-0279, p<0.01) but not with that of impulsiveness. The frequency of 'having milk and milk products' and all processed foods had positive relationships with the scores of impulsiveness and aggression(p<0.01). Especially, the total score of having processed foods had highly positive relationships with impulsiveness(r=0.656, p<0.01) and aggression(r=0.614, p<0.01). In conclusion, it is very important to have a good dietary habits and to reduce the frequency of having processed foods for children's good personality.

Recently, child safety map making education has attracted attention as a way to reduce crimes against children. In Korea, the Ministry of Gender Equality and Family organized a child safety map making education program in 2011. The program's manual was revised in 2013 and the Ministry implemented it as a project to promote the rights of women and children. Child safety map making education aims to raise a child's understanding of their neighborhood, to have voluntary control and normal consciousness as a local inhabitant, to be aware of wrong behavior and crime, and to be part of creating a safe urban environment. However, when compared to educational programs in other major developed countries, the child safety map making education program in Korea currently does not improve a child's awareness of their surroundings. In this workshop study, we proposed and ran a new program to improve children's awareness of their environment based on the active participation of children in the existing safety map educational program. The workshop was held for 4 weeks for 48 students from 5th and 6th grade at Osan Daeho Elementary School. We analyzed this new program's effects with the following results. First, an analysis of the effects of the program on children's recognition of safe and dangerous spaces revealed that their understanding of these spaces increased by 30.4% after the workshop. The safety-related factor in the mind map key concept increased from 0.94 to 4.94, indicating that the children's perception of neighborhood risk and safety factors improved. Second, the analysis of the effects of the program on the children's coping ability in dangerous situations showed that their understanding of how to deal with dangerous situations increased by 11.3%. The children's understanding of facilities they could ask for help, such as police boxes and child safety guard houses, improved by 17.9%. Third, analysis of the effects of child safety map making education on children's understanding of their neighborhood, their perception of responsibility in the neighborhood, and their neighborhood attachment showed that these levels of children's understanding of the neighborhood improved by 6.0% after the workshop.
