Purpose: Coronavirus disease 2019 (COVID-19) has posed a significant burden to infant and toddler's care globally, while the disease severity is generally mild in this age group. In this study, we aimed to assess epidemiological and clinical aspects of COVID-19 in infants and toddlers in Seoul, South Korea. Methods: We used Seoul Metropolitan Government's epidemiological investigation database to describe the epidemiological and clinical characteristics of COVID-19 in infants and toddlers, between March 2020 to December 2021. Results: A total of 5,025 infants and toddlers aged <5 years was diagnosed between the observed period. 2,720 (54.1%) had symptoms, and fever was the most common symptom in 1,941 (74.1%). Of the diagnosed cases, 96.4% did not have underlying diseases. In a district level, extended opening of childcare facility was associated with increased risk of COVID-19 in infants and toddlers. Conclusions: An efficient monitoring system, resembling routine clinical care, is crucial, considering the low rates of severe progression and fatality among infants and toddlers. Moreover, a well-grounded intervention based on scientific evidence, rather than unconditional closures, is necessary to establish a suitable childcare policy that ensures safety from infectious diseases while not overlooking the developmental aspects of social skills.

This study aims to research the use of smart devices of infants and preschool children, and their mothers' perception about it. Moreover, the goal of this study is to collect preliminary data about problems from the use of smart devices, and to prevent the problems. Therefore, the questions of inquiry for this study are: 1. How do infants and preschool children use smart devices? 2. How do mothers perceive their children using smart devices? Four hundred and forty mothers, who send their child to a day-care center or kindergarten in Busan, participated in this research and data among 397 of them were analyzed using PASW 18.0 program. The answers to a multiple-choice question were converted into a frequency and percentage. To verify the difference of factors, Chi-squared Test and One-way Analysis of Variance methods were used. The following are findings of this study: 1. Most of the families owning smart devices allow their children to use a smart device when children want it, and children use it for entertainment purpose before their bedtime. Children start to use a smart device mostly around the age of 4. Compared to girls, boys spend a longer time on smart devices playing mobile game. In addition, the research indicated that the children of younger mothers tend to use smart devices in earlier ages than the children of elder mothers. 2. Mothers of preschool children have higher perception about the availability of their child using smart devices compare to the mothers of day-care center. However, the research showed that elder mothers have more positive perceptions about all the other five lower factors, (e.g. educational characteristic, entertainment characteristic, design, safety, and smart recognition).

Objective : The purpose of this study was to examine differences in social maturity and behavioral problems according to the level of sleep problems in children with ASD. Methods : The participants were 102 mothers of infants with ASD aged 1-5 years. The Social Maturity Scales (SMS) and Child Behavior Checklist 1.5-5 were used as the measuring tools. Results : The level of sleep problems in infants with ASD was 56.58T on the sleep problems scale. The participants were grouped based on scores on the sleep problems scale: those with scores <65 (good sleepers) or scores ≥65 (poor sleepers). Sleep problems significantly correlated with all the scales on the CBCL. However, no association was found between sleep problems and social quotients. Poor sleepers achieved significantly lower scores on the social quotient scale of the SMS than good sleepers. Poor sleepers achieved significantly higher scores in internalizing problems, externalizing problems, and DSM-oriented scales on the CBCL compared to those in the good sleepers. Conclusion : The significance of this study is that it has verified the severity of sleep problems in infants with ASD and has examined the differences in social maturity and behavioral problems between poor sleepers and good sleepers.

The purpose of this study was to determine if teachers' perception of professionalism, teaching intentions, and the quality of teacher-child interactions differed by teachers' education and career and how those variables were associated with one another. It was conducted in 50 teachers who were in charge of two- to five-year-olds at 22 national/public, private, and employer-supported childcare centers in Seoul and Gyeonggi Province. Arnett's (1989) Caregiver Interaction Scale (CIS) translated by Choi and Shin (2015) was used to measure the quality of teacher-child interactions, and the Current Status and Self-Desire for Professional Competence scale developed by Wang (2005) and translated and revised by Jeong (2016) was used to measure a teacher's perception of professionalism. The Teaching Intention Scale (TIS) developed by Wilcox-Herzog and Ward (2004) and translated and revised by the researcher was used to measure teaching intentions. The researcher and the research assistant personally visited the centers to observe the teachers for the quality of teacher-child interactions and a questionnaire for teachers was used to determine a teacher's perception of professionalism and teaching intentions. For data analysis, t-test and Pearson's product-moment correlation analysis were performed on the basis of the questions. The results of this study can be summarized as follows: First, the quality of teacher-child interactions differed insignificantly by education or career. Second, teacher's perception of professionalism differed significantly by teachers' career but differed insignificantly by education: the longer career, the better perception of professionalism. Third, teaching intentions differed insignificantly by education or career. Fourth, teachers with better perception of professionalism showed higher quality of teacher-child interaction. Fifth, The higher level of teaching intentions teachers showed the more sensitive interactions they made with children.

This study aimed to develop a reliable and valid developmental test for toddlers and preschoolers. A trial form of the test with 230 items in 5 domains(cognitive, physical, language, social, and self-help) was constructed and administered to 200 children from 2 to 5-year-olds. Item analysis indicated that most items selected in cognitive, physical, and indicated domain were acceptable in terms of item response rate and item discrimination. However, some items in social and self-help domain did not show clear age trends in item response, but mostly were adequate in item discrimination. Based on item analysis, 112 items were selected for the final form : 24 items each for the cognitive, physical, and language domain; 20 items each for the social and self-help domain. Reliability indicated by internal consistency coefficients(KR-20) were high in all domains. Validity of the test was supported by inter-correlations among 5 domains(.61 to .93), and significant age differences in domain scores.
