This study argues the nature of the microgenetic method in respect to child development research and explores its merits and limitations. The microgenetic method focuses on observations that span the entire period from the beginning of developmental change to the time it reaches a relatively stable state. This produces a high density of observations relative to the rate of change in the phenomenon. In this way, observed behavior may be used in intensive trial-by-trial analysis. The microgenetic method is superior to other methods in the possibilities for observing developmental changes as they occur, examining various aspects of change, detecting variability in behavior, and flexibility in application regardless of theoretical perspectives. Limitations of this method include reliability problems due to repeated observations, artificiality relative to the natural situation, inconsistency of short-and long-term change, and demands on children's motivation for participation in research.

Emotion is a central feature of social interactions. In this study, we examined age-related changes in emotion expressiveness and emotion knowledge and how young children's emotion expressiveness and knowledge were related. A total of 300 children attending a daycare center contributed data for the study. Observation and interview data relevant to measures of emotion expressiveness and knowledge were collected and analyzed. Both emotion knowledge and expressed positive affect increased with age. Older preschool children expressed positive affect more frequently than did younger preschoolers. Older preschool children also labeled, recognized, and provided plausible causes mores accurately than did younger preschool children. In addition, we tested whether children's errors on the free labeling component conform to the structural model previously suggested by Bullock and Russell (1986) and found that preschool children were using systematic strategies for labeling emotion states. Relations between emotion expressiveness and emotion knowledge generally were not significant, suggesting that emotional competence is only gradually constructed by the child over the preschool years.

The purpose of this study was to investigate the seating style of children between Korea and USA viewed from activity analysis in child-care centers. Observation and depth-interview method were used for data collection. Ninety-eight children aged from 38 to almost 62 months were observed for five minutes three times during an indoor free play period in Korea and USA in 2003 and 2004. The results of the research were as follows. There were significant differences between the postures of Korean and American children. Korean children maintained floor-seating postures longer than chair-seating and standing postures. The factors such as sex, age and physical environment influenced the children's seating style, while playing-type influenced their posture. This study will contribute to our understanding of the physical environment and children's seating style according to culture.

The present study conducted in the Children's Museum investigated patterns of participation by type of exhibit and interaction with 150 5-to 12-year-old children and 50 mothers. A timing and tracking observation checklist was used to document time spent at each type of exhibit and the interaction of children and mothers. All children chose and spent more time interacting with participatory than non-participatory exhibits and they chose more participatory exhibits than mothers. Mothers chose more non-participatory than participatory exhibits and spent more time with non-participatory exhibits than the preschool group. The preschool age group interacted with mothethan other interactions.

In this study of the formation of concepts of inclusion by non-disabled preschoolers in inclusive classroom settings, the researcher conducted participant observation and in-depth interviews from March 2004 through June 2005 in a single day care center offering inclusive education in Kyung-gi Province. The non-disabled children exhibited changes in their conception of disability through interactions with disabled children. The non-disabled children could be grouped into three categories: those who were wary of or disregarded disabled peers; those who disregarded disabled peers while helping them out; and those who actively cared for their disabled peers. Not all children went through the same developmental stages. The speed and degree of change in conception varied depending on the individual.

Purpose: This study was done to evaluate the effects of distraction using balloon art on pain experienced by preschool children when undergoing an intravenous injection. Methods: Participants were 40 hospitalized preschool children. Children in the experimental group (20) were distracted by balloon art while undergoing an intravenous injection. Children in the control group (20) received regular care. Pain experienced by the children was measured using self-report, observation tools, heart rate and oxygen saturation. The data were analyzed using the SAS program. Results: Compared with the control group, children in the experimental group showed significant difference in pain as shown by pulse rate. However, children in the experimental group did not show a decrease in pain in the self-report or behavior observation when compared with children in the control group. Conclusion: Distraction using balloon art can be used to reduce pain for preschool children when undergoing an intravenous injection. Further nursing interventions need to be developed and provided to preschool children when undergoing painful procedures.

This study is designed to positively transform a teacher's emotional state whilst teaching their classes and be able to create happier lessons for preschool children. To do this, a teacher needs to reflect upon current problems and take steps to deal with them. The data for this study was collected from participatory observation and in-depth interviews, making use of photos, a reflective teacher's journal and interview records from Mar. 28, 2011 through Oct. 7, 2011. The problems identified were, (1) teacher centered classes, (2) a daily routine filled with large group activities, (3) disruptive students, and (4) repetitiveness. The routes to greater classroom "happiness" are (1) rearranging seats, (2) "story sharing activities" in small groups, (3) making a separate "story sharing activity" area, (4) using small groups instead of large groups, (5) changing the daily routine. The role of the teacher in finding greater "happiness" are (1) meaningful, 'real observation', (2) discovering genuine change from small points, (3) power sharing, and (4) growing and developing with children.

A double bhad, placebo controlled study was performed to evaluate the therapeutic effects of Carbamazepine in autistic children, 23 boys with the diagnosis of Pervasive Developmental Disorders according to the DSM-IIIR were selected for study subjects, from Child and Adolescent Psychiatric Outpatient Department of Seoul National University Children Hospital during Oct. $1989{\sim}Nov.$ 1991. Subjects with histories of medical disease or psychiatric diseases were excluded and all study subjects had drug free periods more than 2 Months. Study subjects were randomly assigned to Cabamazepine treatment group(N=12) and placebo group(N=11). After the baseline observation periods, the double blind drug treatment and observation were performed for 12 weeks. Several scales (Ritvo-Freedman Real Life atring Scale. Behavior Checklist) were employed to evaluate the effects of drug treatment during baseline observation periods and the drug treatment periods by two raters blind to the study. Interrater reliability of each scales were .4875~.6613, the socrodemographic variables and the rating scores during baseline observation periods were not significantly different between two groups. Reduction of total scores in Autsm Behavior Checklist scale, i.e.. improvement of global autistic symptoms were noted significantly in Carbamazepine treatment group. Improvement in significant social maturations according to Vineland Social Mataration scale were observed in both patient groups after drug treetment periods.

Purpose: There are many forest and outdoor programs being offered but systematic reviews of effects are lacking. This study was done to identify content, format, and strategies of forest therapy programs for elementary school students. Methods: Literature search using keywords in English and Korean was performed using 6 electronic databases in December 2016. Search participants were elementary school students and interventions conducted in the forest. Seventeen forest therapy studies were selected for evaluation. Risk of Bias Assessment tool for non-randomized study was used for quality assessment. Results: All studies were quasi-experimental designs. Forest therapy programs included various activities in forests such as experience of five senses, meditation in the forest, walking in the forest, ecological play, observation of animals and insects. All studies used psychosocial health variables and forest healing programs had positive effects on sociality, depression, anxiety, self-esteem, stress, aggression, anger, and school adjustment. Limitations of these studies were vague reporting of the study, lack of ethical review and rigorous research designs. Conclusion: Forest therapy for elementary school child can be an effective way to improve psychosocial health. Future studies with rigorous study designs are needed to assess long-term effects of forest therapy on physical and psychosocial health.
