This study examined how parent-child attachment, parental involvement in child rearing and instruction for children's effective use of a smart device reflect on young children's smart device overuse behavior. We collected questionnaires from 196 parents with children attending early childhood education institutions for the survey. Frequency analysis as well as Person correlation coefficient and regression analysis were conducted using IBM SPSS 21.0 statistics. The results showed that 91% of targeted young children were using a smart device and 78% first used them before age 5. As for time of use hours, 43.9% used their smart device from 30 minutes to 1 hour on average. In addition, parent-child attachment and father's involvement in child rearing were found to be inversely correlated to young children's smart device overuse. The result of hierarchical regression analysis on parent factors influencing young children's smart device overuse behavior indicated that mothers' contact-seeking behavior to young children, mother's involvement in learning and instruction for children's effective use of a smart device at home had beneficial effects. This study analyzed parent factors that influenced young children's smart device overindulgence. In addition, the baseline data of this study will be utilized to develop programs for the prevention and therapy to solve the smart device overindulgence as well as to establish young children's guidelines for using a smart device.

In order to investigate correlation between mother's dental ca re for her children and their dental caries, this study was conducted wi th the dental examination record of 365 children who showed the same number of questionnaires with those examined for dental conditions and questionnaires written by mothers among children between three and six years of age and their mothers in Yeoncheon, Gyeonggi province in June 2004 to estimate frequency and percentage of general properties of subjects and mother's oral health care behaviors for her children by research items, to carry out cross-tabulation analysis and correlation analysis following Chi-square distribution for the presence of dental caries in deciduous teeth and oral health care behaviors, and to use decision tree analysis among data mining techniques for those factors associated with the presence of dental caries in deciduous teeth, and drew the following conclusions. 1. For mother's oral health care behaviors and attitudes for her children, 225 mothers(61.6%) confirmed their children's teeth-brushing; 278(76.2%) used no fluorine; and 286(78.6%) observed their children's teeth, 322 mothers(88.2%) instructed their children in teeth-brushing while 268 (73.4%) provided dental care, 232 mothers(63.7%) treated their children's cavity; 290(79.4%) believed that their children had good dental conditions; and 294(80.5%) answered that they began to provide their children with dental care in deciduous teeth. 2. As for the presence of dental caries in deciduous teeth and dental health care behaviors, there were statistically significant differences in employment, confirmation after teeth-brushing, teeth observation, instruction in time for teeth-brushing, use of fluorine, cavity treatment, time for dental care, and perception of dental conditions(p<0.05). 3. As for correlation between dental caries in deciduous teeth and oral health care behaviors, mothers who worked, who believed that their children didn't have good dental condition, and who thought that it was necessary to begin to provide dental care in permanent teeth were found to get their children to suffer from dental caries in deciduous teeth. Besides, those who failed to confirm teeth-brushing, who used no fluorine, and who failed to observe teeth and gave no instruction in time for teeth-brushing were shown to get their children to suffer from dental caries in deciduous teeth. 4. Variables to determine the presence of dental caries in deciduous teeth were classified by cavity treatment, mother's employment, time for dental care, and observation of children's teeth. The first node to determine the presence of dental caries in deciduous teeth was found to be cavity treatment; the next criteria for classification after cavity treatment were shown to be mother's employment and time for dental care. In case of children with no cavity, they were found to be mother's employment and teeth observation.

This study analyzed the effect of parent-child communication and peer relationship on children's internet addiction. The subjects were 642 elementary school students living in Daejeon city. Cronbach's $\alpha$, t-test, ANOVA, and Duncan's test were employed in analyzing the data by using SPSS 10.0. The findings of this study were as follows First, the boys were more addicted to internet use than the girls, as were the children of less educated parents. The children of parents with professional careers were less addicted to the internet. The children who perceived their school achievements as low were more addicted to the internet. Second, the children who spent more time daily, longer time at once and more frequently per weekly internet use were more addicted. Third, internet addiction was influenced tv parent-child communication and peer relationship. Boys who had more problem communications with their parents less open communication with their mother and a lower level of peer support were more addicted to the internet. The problem of communication with their mother and conflict in their peer relationship had more influence on the internet addiction of girls.

This research aimed to observe adolescent children's use of time and to discover the parent-related factors that affect adolescent children's use of time. The subjects included 2,092 fourth-grade elementary school students and 2,108 first-grade middle school students. We used data from the Korean Children and Youth Panel Survey. We tested sociodemographic factors, parents characteristics, and time usage, and we studied these factors using SPSS version 23.0; the results are as follows. Firstly, in the subordinate scope of the child-rearing attitude of parents, affection fourth-grade elementary school students(M = 1.83) and first-grade middle school students(M = 2.02). Inconsistency had an effect on fourth-grade elementary school students(M = 1.99), and first-grade middle school students(M = 2.12). Excessive expectations had an effect on fourth-grade elementary school students(M = 2.40) and first-grade middle school students(M = 2.55). Over-involvement had an effect on fourth-grade elementary school students(M = 2.68)and first-grade middle school students(M = 2.80). Finally, giving reasonable explanations had an effect on fourth-grade elementary school students(M = 1.51)and first-grade middle school students(M = 1.68). Secondly, in fourth-grade elementary school students(M = 463.35) and first-grade middle school students(M = 378.75). Further, studying hours during weekdays had an effect on fourth-grade elementary school students(M = 456.15) and first-grade middle school students(M = 460.86). Free activity hours during had an effect on fourth-grade elementary school students(M = 390.54) and first-grade middle school students(M = 387.11). Sleeping hours during holidays had an effect on fourth-grade elementary school students(M = 544.85) and first-grade middle school students (M = 511.74). Studying hours during holidays had an effect on fourth-grade elementary school students (M = 484.86) and first-grade middle school students (M = 511.74). Free activity hours during holidays had an effect on fourth-grade elementary school students(M = 518.68) and first-grade middle school students(M = 509.73). Thirdly, by observing the relative influence of related factors on adolescent children's use of time, grade(${\beta}$ = -.284), gender(${\beta}$ = -.208), over-involvement(${\beta}$ = -.380), supervising(${\beta}$ = -.217), and (${\beta}$ = .243) in terms of the child-rearing attitudes of parents was found to affect study hours($F=2.595^{**}$). The education level of fathers(${\beta}$ = -.144) results in(${\beta}$ = 1.991) and longer free activity hours for children($F= 4.116^{***}$).

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in face-to-face classes worldwide, affecting the mental health of children and their parents. The global pandemic has increased children's overall use of electronic media. This study analyzed the effect of children's screen time on problematic behaviors during the COVID-19 pandemic. Methods: A total of 186 parents from Suwon, South Korea, were recruited to participate in an online survey. The mean age of the children was 10.14 years old, and 44.1% were females. The questionnaire included questions on children's screen time, problematic behaviors, and parental stress. Children's behavioral problems were evaluated using the Behavior Problem Index, whereas the Parental Stress Scale was used to estimate parental stress. Results: The mean smartphone usage frequency of the children was 5.35 days per week, and the mean smartphone screen time was 3.52 hours per day. Smartphone screen time (Z=4.49, p<0.001) and usage frequency (Z=2.75, p=0.006) were significantly correlated with children's behavioral problem scores. The indirect effect of parental stress on this relationship was also statistically significant (p=0.049, p=0.045, respectively). Conclusion: This study suggests that children's smartphone screen time has affected problematic behaviors during the COVID-19 pandemic. Furthermore, parental stress is related to the relationship between children's screen time and problematic behaviors.

Background: Despite children's unique characteristics that distinguish them from adults, relatively few attempts have been made to measure exposure factors for characterization of children's exposure to hazardous chemicals in child-specific products (CSP). This study was conducted to establish the child-specific exposure factors for exposure and risk assessment of hazardous substances in CSP. Methods: We investigated the exposure factors (e.g., time use of child-products, time and frequency of object-to-body contact, time and frequency of object-to-mouth contact) influencing children's exposure to CSP (e.g., toys, playmats, oil pastels, etc.) in 650 children through a parent-completed questionnaire using a web-based survey. Participants were recruited in five age groups, <1, 1-2, 2-3, 3-6, and 6-12 years of age. Results: The child-specific exposure factors were presented as the mean, median, $95^{th}$ percentile, minimum, and maximum values. Time activity for play mats was the longest among CSP and infants spent more time on them than did elder age groups (189.3-224.7 min/day for <1-2 years vs. 91.2 min/day for 6-12 years). It is apparent that time and frequency of toy block- and plastic toy-to-mouth contact significantly decreased as a function of age. When the variation of CSP use patterns was compared by gender, the only variable that was statistically different between genders was time activity in child-products exposure space. Conclusion: We believe the five child-specific exposure factors suggested in the present study will be valuable for reducing uncertainty in the estimation of chemical exposure during risk assessment of CSP and furthermore, in the appropriate regulations to protect children's health.

This study focused on the role of prefabricated speech (routines and patterns) in the L2 acquisition process. The data for this study consisted of spontaneous speech samples and various observational records of three Korean children learning English as L2 in a nursery school. The specific questions addressed here were: (1) What routines, patterns, and creative constructions did the children use? (2) What was the general trend in the three children's use of routines, patterns, and creative constructions over time? The data were collected over a period of one school year by observing the children in their school. The findings were discussed from the perspective of human information processing. This study found that prefabricated speech played a significant role in the three children's L2 acquisition. The automatic processing of prefabricated speech appeared to enable the children to reduce the burden on their information processing systems, which allowed the saved resources available for other language development activities. Also, the children's language development was evident in their increase in the use of patterns. The children were moving from heavy dependence on wholly unanalyzed routines to increased use of partly unanalyzed patterns. This increased control was the result of an increase in procedural knowledge.
