The purpose of this study was to examine the use of dentifrice among preschoolers in an attempt to provide consumers with the right information on the choice of dentifrice and toothbrush for different age groups of children. The subjects in this study were parents who raised preschoolers in Seoul and Gyeonggi Province. A self-administered survey was conducted over approximately three months from May to July 2007 to find out the state of their children's use of dentifrice. After the collected data were analyzed, the following findings were given: The greatest group (51.5%) needed parental help with toothbrushing. The biggest group of the patients (35.6%) considered it necessary for children at the age of 6 and 7 to brush their teeth with the help of their parents. As to dentifrice squeezing and parental outlook on that, the biggest group of the parents (49.4%) replied their children squeezed the dentifrice for themselves, and the greatest group (42.2%) thought that children needed parental help with dentifrice squeezing by the age of five. Regarding dentifrice swallowing and parental perception of it, the biggest group (61.9%) saw their children swallowing the dentifrice, and the greatest group (73.7%) believed that children must not swallow the dentifrice. The biggest group of those who found it okay for children to swallow the dentifrice (62.5%) thought that it would be no problem to swallow the dentifrice for child. Concerning the use of toothbrushes, the biggest group (96.7%) had their children use toothbrushes for child. The above-mentioned findings of the study showed that the children who are at the age of 3 or down should use non-fluoride containing dentifrice or just a small amount of fluoride that is as equal as the size of a pea. Children must brush their teeth under the guidance of their parents, and sustained education should be provided about that.

The study aimed to examine the state of visual acuity tests in preschoolers and determine the factors affecting the deterioration of their vision. A total of 172 pair, child aged 5-7 years and either one of their parents, were recruited from childcare centers or kindergarten between August 2015 and January 2016. Questionnaires were administered to the parents, and the children's visual acuities were measured. Using forward selection in logistics regression analysis, factors affecting vision deterioration were elucidated. Of 172 children, 128 (74.4%) had undergone a visual acuity test previously and 77 (44.8%) showed a deterioration in their vision. Children who had undergone their first visual acuity test after the age of 7 years (OR=7.425, CI=2.844- 19.385) and showed more abnormal eye symptoms, such as squinting or tilting the head to see or falling down frequently (OR=3.084, CI=1.202-7.914) and whose age was younger (OR=10.335, CI=3.252-32.848), were more likely to develop deterioration of vision. Children who had a posture such that they looked up at the computer monitor from below (OR=.075, CI=.022-.255), were less likely to show deterioration of vision. It can be inferred that early visual acuity tests is essential to detect deteriorated vision of preschoolers. Therefore, it is necessary to educate parents, personnels in day care center, and health clinics about the importance of early visual acuity tests and close observation of specific behaviors related to vision deterioration. Development of precautionary intervention program of vision deterioration in preschoolers and examination of its effects are needed.

This study was to conduct a literature review and a theoretical study on 95 environmental education programs currently being run in the metropolitan area and obtained Environmental Education Program Certification of Ministry of Environment. First, the suitability of the environmental education programs was analyzed in terms of the following criteria which the Second National Environmental Education Master Plan propose: strengthening environmental education within the curriculum, strengthening preschooler environmental education, diversification of environmental education among targeted groups, and invigoration of community-based environmental education, and evaluated the contents and the proportion relevant to climate change. Based on the result, the measure for the improvement of the environmental education programs was proposed. As a result of the analysis, there were only 15 programs for children, and 20 programs for adults. Also, only 9% of the children and adult education programs were addressing climate change respectively, which was indicating low percentage. 75 programs were directly related to the school curriculum, and 8 programs were not related to subjects in regular curriculum. Also, considering addressing climate change, 7 out of 11 programs were related to the school curriculum. 71 out of 95 programs were located in the facilities of local governments. Programs that were including the contents relate to climate change were only 11 out of 95 programs. It is necessary to operate programs by expanding environmental education programs targeting children and adults, so all people are took into account, and consider the connectivity between curriculum and environmental education program in South Korea to increase the effectiveness of education. Also, it is necessary to educate people sustainably by relating the programs with various resources which can be utilized in the local community, to include climate change related contents with more proportion, and to address various subjects rather than focusing on one part of the subjects.

The purpose of this study is to reveal the insights that teachers has learned through developing preschooler's classroom into field-trip-oriented ones with role play areas. The data of this study was collected from participatory observation and in-depth interviews, which included videos, photos, teachers' journal, descriptive questionnaire, and interview records. The whole process of organizing role-play oriented class was composed of four steps: activities before the trip, activities on-the-spot, activities after the trip, and its evaluation. Firstly, activities before the trip were making the lists of questions, deciding children who ask the questions, making rules on the trip, understanding the purpose of the trip. Secondly, on-the-spot activities included having a tour of the place and asking the questions. Thirdly, activities after the trip was constructing the classroom into small real world with various sections. This required the teachers to reflect the field trips, make plans how to construct, prepare for the data, and furnish the classroom with role-play areas. In the process of furnishing the classroom with small real world, the field trips played a big role as the learning opportunities for language development, and keeping public rules.

The purposes of this study were to explore the relations of preschoolers' narrative representation profile types to diurnal cortisol regulation pattern at home. Fourteen story stems from the MacArthur Story Stem Battery (MSSB, Bretherton, et al., 1990) were administered to 40 preschoolers(22 boys, 18 girls, aged 5) recruited from 8 kindergartens in the Seoul and Gyeonggi areas. And also, their saliva cortisol was collected. The children's responses were aggregated into 5 dimensions, based on content themes and performance scores, which included emotions expressed and narrative coherence using the MacArthur Narrative Coding System(Robinson, et al., 2004). Data were analyzed by means of cluster analysis. Five response profiles emerged over the course of this research: Prosocial, Anxiety, Dyregulated aggression, Restricted, and Avoidance profiles. Cortisol at home showed decrease diurnal cortisol regulation patterns, however it showed a difference according to narrative response profiles. Restricted, Prosocial, and Avoidance profiles showed decrease diurnal cortisol regulation patterns. Anxiety profiles showed flat pattern, and Dyregulated aggression profile showed rising diurnal cortisol regulation pattern. These results show the preschoolers' internal representation may affect the diurnal cortisol reaction in daytime.

Objective: This study aimed to investigate the trajectory of maternal parenting stress during infancy according to the employment status of mothers when each year's depression was controlled and examine the longitudinal effects of parenting stress on affective parenting and socioemotional developmental outcomes for preschoolers. Methods: Using latent growth modeling, the first 4 waves of panel data collected from 2,078 mothers and their babies were analyzed. This nationwide data was provided from the 2008 Panel Study on Korean Children, conducted by the Korea Institute of Child Care and Education. Results: First, maternal parenting stress showed a linear increasing pattern, and there were individual differences in intercept and slope. Second, when each year's maternal depression was controlled, the intercept of parenting stress was lower, but the rate of increase was higher. In multiple group analyses, this increasing pattern of parenting stress was significant only in unemployed mothers. Lastly, the increase of unemployed mothers' parenting stress had direct effects on child emotionality and peer interaction and had an indirect effect on child peer interaction (mediated by affective parenting). Conclusion: The current study verified that the longitudinal effects of increasing parenting stress of unemployed mothers on affective parenting and child socioemotional development when maternal depression level was controlled. These results imply that we need to pay more attention to emotional health and resources of unemployed mothers and provide them with social support as well as employed mothers.

This paper investigates the parenting stress of fathers who have preschooler. At first, a causal model constructed, including the parenting stress as a dependent variable and the psychological characteristics of paternal self-esteem and parenting efficacy as parameters. Based on the change of parenting stress, self-esteem and parenting efficacy according to various pertinent to fathers, the causal effect of various variables effecting on the paternal parenting stress is analyzed. The SPSS PC program was used for the statistical analysis, where fully exploited were frequencies, percentages, means, standard deviations, Cronbach α, one-way analysis(ANOVA), path analysis. The results can be summarized into 3 parts, in conclusion: 1) The younger a father is, the higher paternal self-esteem becomes. Paternal self-esteem trend was there, for a father who is a member of large family, and for a father whose education level is high, and for a father whose occupation is professional. Regarding parenting sense of competence, a father shows confidence when he has more income, more educated and less children. 2) The variable analysis effecting on the parenting stress dut to the paternal environment shows that a father feels more stress when his income is less and his spouse is working. The sub-factor analysis on the parenting stress shows that 'typical stress dut to the parenting' increases when his income is less and his spouse is working, and 'pressures pertaning to the parental role and distress' increases for a father with less income, working spouse, less educated and non-professional job. Further 'guilty to the parenting by others' shows higher for a father with less income and a working spouse. 3) The path analysis, which were performed to check the causality of the parenting stress dut to various variables, shows that the self-esteem and the parenting efficacy are significant factors directly effecting on the paternal parenting stress, and the job-satisfaction and marriage-satisfaction are significantly effecting on the parenting stress both directly and indirectly.

This study investigated the relationship between preschoolers' smart media usage in regards to cognitive and language development, especially the mediating effect of preschoolers' smart media addiction tendency and the moderated mediating effect of maternal guidance on smart media usage. The study surveyed 273 preschoolers' mothers who lived in Daegu City and Kyungpook Province. The findings of this study were as follows. First, preschoolers' smart media addiction tendency mediated the relationship between smart media usage time in regards to cognitive and language development. Second, maternal active mediation and monitoring moderated the relationship between preschoolers' smart media usage time and smart media addiction tendency. Third, there was a maternal co-use moderated the mediating effect of preschoolers' smart media addiction tendency on language development. In conclusion, preschoolers' smart media addition tendency mediated the effect of smart media usage time on cognitive and language development. Among the mediation pathways, the influence of preschoolers' smart media addiction tendency on language development was moderated by maternal co-use. The findings of this study suggest that maternal guidance should be applied differently depending on preschoolers' smart media addiction tendency. This study examined preschoolers' and maternal smart media-related variables on preschoolers' cognitive and language development in order to provide preliminary data that can be used to explore the maternal guidance on how to use smart media for their preschool children.

The principal objective of this study was to identify the dietary and physical activity patterns of obese preschoolers, and to determine the association between child obesity and mother's' dietary habits or thoughts regarding dieting/weight. This is a cross-sectional, community based study, and 305 preschoolers who attended kindergarten in Seoul and its surrounding area were selected. The measurements of dietary habits both in preschoolers and their mothers, physical activities of preschoolers, and daily servings of foods were based on parents' self report. Weight and height were used to calculate WLI (weight length index) in preschoolers and BMI (body mass index) in their mothers. The subjects were divided into two groups 245 normal weight preschoolers (including underweight 15.1% and normal weight 65.6%) and 59 obese subjects (overweight 14.4% and obese 4.9%). With regard to dietary habits in normal and obese preschoolers, we noted significant differences in 5 questions, such as mostly eating heavy meals, one serving size, eating speed, overeating, and obsession about eating. No differences in daily servings of major foods and snacks, except fruits and potatoes, were noted between normal and obese children. Among 13 questions regarding mothers' dietary habits, only 3 questions-"preferred to instant foods", "finish meals within 15 minutes", "use nutritional information for selecting foods" were significantly different between normal and obese subjects. The total scores of mothers' dietary habits was significantly and negatively correlated with number of mother's dieting experiences or mother's BMI, but was not correlated with preschooler's obesity.
