Dental erosion is a complex disease of multifactorial etiology with high risk of loss of tooth structure, which still has not been appropriate interest. The aim of this study was to assess the prevalence and risk indicators of dental erosion in Korean school children. A cross-sectional survey was performed on 664 children aged 8~9 years. Data concerning gender, types of caregiver, dietary habits, oral hygiene habits and parental knowledge were obtained from a questionnaire, which was answered by the parents of the children. Association between erosion and the factors were statistically analyzed with chi-squared test and independent t-test at a significance level of 0.05. Dental erosion was present in 242 children. In carbonated drinks, dental erosion was significantly associated with preference, frequency of consumption and the ingestion method (p < 0.05). In fruit juices, dental erosion was significantly associated with preference and frequency of consumption (p < 0.05), but no significant associations were found with the ingestion method (p > 0.05). There were no significant associations between dental erosion and gender, type of caregiver, oral hygiene habits and parental knowledge (p > 0.05). In conclusion, it was considered that motivation to be followed by practice is important as well as education for prevention of dental erosion.

The purpose of this study was to identify the relationship between self-esteem, self- efficacy and clinical practice performance, academic achievement, decision making of major field in clinical practice . The study subjects consisted with 244 students from G. junior nursing college that will adapt a new majoring program of clinical nursing practice funded by Ministry of human and resources development. Data were analyzed using descriptive statistics, and t-test, Pearson correlation, and multiple regression. The results of this study were summarized as follows: 1. The students were relatively performed well in clinical practice setting (total M :3.78). The item of student's personal relationship between patients, patient's family, and professional staff showed high score (M=3.96). However students did not feel comfortable to communicate with patients, patient's family and professional staffs in clinical setting(mean=3.56). 2. Students who had experiences of temporal absence from school showed significant difference in the variable of academic achievement and decision making of major field in clinical practice Students who entered to nursing school with self-motive revealed statistically significant difference in the variable of clinical practice performance, academic achievement, self-esteem, self-efficacy, and decision making of major field in clinical practice. 3. There was a significant correlation between self-esteem and clinical practice performance, (r=.512, p<.000). And the relation between self-esteem and decision making of major field in clinical practice was significantly correlated(r=.377, p<.000). Self-efficacy and clinical practice performance(r=.567, p<.000), and decision making of major field in clinical practice (r=.441, p<.000) showed significant correlations. Also relation between academic achievement and self-esteem reveled a significant correlation(r=.129, p<.05) but correlation between self-efficacy and academic achievement was not significant. 4. Correlation between clinical practice performance and decision making of major field in clinical practice also identified a significant relation(r=.498, p<.000). 5. Self-esteem and self-efficacy variables predicted clinical practice performance and explained 37.7% of clinical practice performance. 6. Aptitude and personal interests(m=4.07) reveled important factor affecting to select majoring area in clinical practice, and advice from parents reflected low percentage on selecting places(m=2.42). In conclusion, the variables of self-esteem and self-efficacy showed significant correlations with the variables of student's clinical practice performance, academic achievement, and decision making of major field in clinical practice. Thus it is recommended that student's affective domain of self-esteem and self-efficacy should be developed by nursing intervention before clinical nursing education.

The purpose of this study is to estimate the direct and indirect effects of relevant variables on students' science achievements. Path analysis was conducted with data from middle school to examine the effects of perceived positive parenting attitudes, attitudes toward science, science inquiry skills on the science achievements of middle school students. A total of 502 middle school students from the metropolitan area participated in this study. Results suggest that students' perceptions of positive parenting attitudes had no direct influence on their science inquiry skills. However, the students' attitudes toward science and science inquiry skills were found to have meaningful direct effects on their achievements. Students' perception of positive parenting attitudes also presented a significant direct effect on their attitude toward science. In addition, the students' perceived positive parenting attitude revealed an indirect effect on science achievement, through their own attitudes toward science and science inquiry skills. Research findings called for more educational programs and teaching methods considering students' attitudes toward science and science inquiry skills to improve their science achievements. At home, parents need to have positive parenting attitudes to influence their children's attitudes regarding science.

This study investigated the experience and practice of elementary school students on nutrition education. The data were collected from 217 male and female students attending 5-6th grade elementary schools in Seoul and Kyunggi-Do from March to June 2007, interviewing face to face by a nutrition teacher and 3 interns of a nutrition teacher. The results were as follows: 86.5% of the subjects learned about 'Table etiquette', 'Reasons for eating fruits and vegetables'(78.7%), 'Food waste and environment'(72.3%), 'Healthy snacks'(55.7%), 'Food sanitation'(52.3%), 'Food culture of foreign countries'(48.1%). Nutrition education experience was significantly different by gender. A total of 43.5% boys responded that they never learned about 'basic food preperation'(p<0.01). They had learned 'Nutrients for body' and 'Food waste and environment' in school, 'Healthy weight loss', 'Food culture of foreign countries', 'Food circulation' on television, Most content('Table etiquette', 'Simple cooking', 'Food sanitation', 'Eating behaviors for health', 'Reasons for eating fruits and vegetables', 'Healthy snacks') was learned from parents. The practice after nutrition education was higher in 'Table etiquette'(2.14), 'Eating fruits and vegetables'(2.07) than others compared with education experience. The most reason of non-practice on nutrition information was 'Troublesome'. In 'Nutrients for body', a boy answered 'Difficult for practice' 20.0%, a girl answered 'Difficult to understand' 32.6%, showing a significant difference between the gender groups(p<0.001). They remembered the 'Nutrients for body'(49.6%), 'Food sanitation'(44.5%) because of 'important content', 'Basic food preparation'(40.6%), 'Food culture of foreign countries'(36.3%) because of 'interesting content', 'Healthy weight loss'(52.0%), 'Eating behavior for health'(44.5%) and 'Healthy snacks'(33.7%) because of 'need for my health'.

The purpose of this study is to suggest educational directions by exploring the stories of changes and expectations experienced by Christian children during the COVID-19 pandemic. For this purpose, nine third- to fourth-grade elementary school children attending the church, were interviewed about their changes and expectations regarding COVID-19. The results identified five areas of experience: daily life changes, school life changes, interpersonal relationship changes, religious life changes, and emotional changes during the COVID-19 period. Daily changes included infection prevention, missing play, leisurely routine, and lethargy. Changes in school life included loss of face-to-face classes and various rule requirements. Interpersonal relationship changes included the difficulties in forming relationships with friends, teachers, parents, and siblings, and religious life changes included loss of face-to-face worship and the restoration of family worship. Various negative emotions were expressed. Analysis of the participants' expectations showed in daily life they wanted to travel and play, return to pre-corona school life, return to face-to-face worship, restore retreats, and develop fun programs as religious life expectations. Based on these children's experiences and wishes, the study suggests that educators need to recognize children's efforts during the COVID-19 period, read their hurt feelings, and develop church programs that include communication, community, and fun elements.

Daily science classes, which have been continued as part of the spread of participatory science culture, has taken the lead in popularizing science as an effective out-of-school experiential and research activity. However, due to the recent COVID-19 situation, daily science classes have also become an environment in which there is no choice but to switch to non-face-to-face or to combine face-to-face and non-face-to-face education. Therefore, in this study, we examine how elementary school students participating in the non-face-to-face daily science class program change their usual fields of interest, perception of science and technology, interest about science, and scientific competency. In addition, the educational effectiveness of the non-face-to-face daily science class improved by comparing the differences in perceptions of students and parents, and future operation plans were sought. As a result of the study, after participating in the non-face-to-face daily science class program, students' interest in science and technology development, future technology, environmental pollution, and social media increased, and their interest in games decreased. Also, students' interest in science and technology activities, interest in science, and scientific competency also increased. This shows that non-face-to-face daily science class education is effective. Therefore, it was suggested that it is necessary to diversify the learning topics and content levels of the daily science class program, to expand the opportunities of non-face-to-face science education for underprivileged learners, and to develop and share science content using the latest media.

With the popularity and the advanced graphics hardware technology of mobile devices, various mobile applications that help children with physical activities have been studied. This paper presents SandUp, a mobile application that guides the play of building sand castles using artificial intelligence and augmented reality(AR) technology. In the process of building the sandcastle, children can interactively explore the target virtual sandcastle through the smartphone display using AR technology. In addition, to help children complete the sandcastle, SandUp informs the sand shape and task required step by step and provides visual and auditory feedback while recognizing progress in real-time using the phone's camera and deep learning classification. We prototyped our SandUp app using Flutter and TensorFlow Lite. To evaluate the usability and effectiveness of the proposed SandUp, we conducted a questionnaire survey on 50 adults and a user study on 20 children aged 4~7 years. The survey results showed that SandUp effectively helps build the sandcastle with proper interactive guidance. Based on the results from the user study on children and feedback from their parents, we also derived usability issues that can be further improved and suggested future research directions.

This study examined the relationship between physical education and externalizing(aggression) and internalizing(depression, social withdrawal) problem behaviors among adolescents. The moderating role of gender and time in the association between physical education and problem behavior was also identified. This study used data from the second, third, and fourth waves of the middle school student cohort (N=2,133, N=2,151, N=1,979) of the Korean Children-Youth Panel Survey(KCYPS). Main analyses involved multilevel growth model with interaction terms. The dependent variables were aggression, depression, and social withdrawal. The independent variables were gender and physical education (exercise hours) at school. The control variables were abuse, school-adjustment, annual household income and parents' highest level of education. The major longitudinal findings of this study are as follows: First, there was significant change according to the passage of time only in aggression among externalizing and internalizing problems. Second, gender differences exist in aggression and depression. Third, exercise hours of physical education had a negative relationship with internalizing problems. Fourth, there were no gender differences over time in both externalizing and internalizing problems. Fifth, the interaction between exercise hours of physical education and time was statistically significant for social withdrawal. Sixth, the interaction between exercise hours of physical education and gender was statistically significant for depression. The results of this study may become an academic basis for suggesting policy directions that promote increased exercise hours in physical education classes at school.

The purpose of this study is to analyze the types of mathematics journals of elementary school students and to understand how they change in mathematics journals as the grade goes up, and to obtain implications in mathematics education. To this end, 170 of the 222 parish mathematics data submitted to the "Math Journal Contest" were analyzed with the consent of both minors and their parents. As for the framework for analyzing math journal types, 12 types were derived through independent analysis between three researchers. The research results showed that first, the type of math journal written by elementary school students is a variety of journals, such as observation, problem making, concept organization, and review. In addition, as a learning area, it was found that math journal showed a noticeable increase in experimental observation, problem making, and concept journal as the grades progressed, while a small number of idea journal and explanatory journals appeared. However, game (winning) strategy building and types declined. It can be seen that this is evolving from a type that requires activity-oriented or simple descriptions to a type that actively applies mathematical concepts. As such, there are 12-type of math journals, but it is necessary to actively use the teaching materials in writing that can be freely expressed in the school setting.
