This study analyzed physical knowledge displayed in the utterances of 10 Korean children 23 - 76 months of age. Utterances were blocked into four-month time periods, except the first two months and classified into 5 categories including properties of physical objects and materials, friction, buoyancy, gravity, and the motion of physical objects. All five types of physical expressions were found in the data of the earliest period the percent age of the properties and motion was higher than the percent of friction, buoyancy, and gravity. Data suggested two transitional points of change in physical knowledge : 2-year-old's descriptions were based only on perceptually salient physical features 3- to 4-year-olds described only end-state results while children older than 4 included systematic causality.

The developmental self-knowledge from preschool to early adolescence was studied from a cognitive-structural perspective. Responses of the subjects to the question "Who am I?" were analyzed by means of a 29-category scoring system. The question was administered to 250 boys and 229 girls from kindergartens, elementary schools and middle schools in Seoul. One way-ANOVA and Duncan test were utilized for the statistical analysis. The major findings of the present study showed that with increasing age there was (1) a significant increase and diversification of self-knowledge. (2) an individual's self-knowledge became more abstract and less concrete, and (3) self-descriptions shifted from the physical to the psychological self.

Purpose: This study investigated the relationships between mothers' knowledge and practice level of cough etiquette and their children's practice level of cough etiquette as perceived by their mothers. Methods: This study was a descriptive correlational study. The data were collected from 160 mothers with preschoolers attending daycare centers and kindergartens in Gwangju, South Korea using self-reported questionnaires. Results: The correct answer rate for cough etiquette knowledge in mothers was 86.0%, mothers' average practice score was 33.65±4.14, and their children's average practice score was 28.39±4.85 out of 48. The correlation between mothers' cough etiquette knowledge and practice level was not statistically significant. However, mothers' cough etiquette practice was positively correlated with children's cough etiquette level as perceived by mothers (r=.35, p<.001). Conclusion: The development of a systematic cough etiquette education program and measurements for both mothers and children according to their developmental stages is important to effectively prevent respiratory infections.

This paper demonstrated how application of evolutionary knowledge to developmental perspectives enhances understanding of human ontogeny. Evolutionary Developmental Psychology (EDP) explains human behavior through evolutionary principles and focuses on ontogeny rather than phylogeny. In this paper, the authors review concepts of evolution, adaptations, and the processes of evolution from EDP perspectives. The definition and basic assumptions of EDP are introduced, followed by explanations of how evolution happens in ontogeny by looking at developmental systems approaches, concepts of ontogenetic and deferred adaptations, evolution of childhood, and brain plasticity. Possible pathways of evolution in ontogeny are also discussed. Finally, some research methodology for applying EDP to child development is suggested with specific hypotheses and studies.

Purpose: This study was done to identify the level of knowledge and practice of self-management on asthma of school-aged children and to provide data for the development of an intervention program to improve self-management on asthma Methods: The participants were 100 school-aged children who were treated currently for asthma in J city located in G province. Data were collected from 25th August to 30th October 2014. Results: The mean scores were 14.37 of 20 for self-management knowledge (percentage of correct answer 71.9%), 21.65 of 30 for self-management practice. There were significant differences in knowledge according to grade, diagnosed age, food allergy, education on asthma and hardship in school life, and in practice according to gender and economic status, hardship in school life and experience of first-aid on asthma. There were positive correlations between knowledge and practice. Conclusion: Results indicate that school-aged children' knowledge and practice in self-management of asthma were not sufficient enough to perform accurate management of asthma. Therefore, to improve self-management ability of school-aged children to manage effectively asthma, educational strategies that focus on increasing knowledge need to be developed.

Objective: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairment in social skills and communication with repetitive behaviors. Etiology is still unclear although it is thought to develop with interaction of genes and environmental factors. Oxytocin has extensive effects on intrauterine brain development. Vitamin D, affects neural development and differentiation and contributes to the regulation of around 900 genes including oxytocin receptor gene. In the present study, the contribution of D vitamin receptor and oxytocin receptor gene polymorphisms in the development of ASD in Turkish community was investigated. To our knowledge, this is the first study examining these two associated genes together in the literature. Methods: Eighty-five patients diagnosed with ASD according to DSM-5 who were referred to outpatient clinics of Child and Adolescent Psychiatry of Başkent University and Mersin University and 52 healthy, age and gender-matched controls were included in the present study. Vitamin D receptor gene rs731236 (Taq1), rs2228570 (Fok1), rs1544410 (Bsm1), rs7975232 (Apa1) polymorphisms and oxytocin receptor gene rs1042778 and rs2268493 polymorphisms were investigated using real time polymerase chain reaction method. Results: No significant difference between groups in terms of distribution of genotype and alleles in each of polymorphisms for these genes could be found. Conclusion: Knowledge of genes and polymorphisms associated with the development of ASD may be beneficial for early diagnosis and future treatment. Further studies with larger populations are required to demonstrate molecular pathways which may play part in the development of ASD in Turkey.

This study examined the role of maternal attribution in Parenting behaviors. Using an attributional model, it assessed whether maternal attributions about children's knowledge, capacity, expectation, and responsibility for behavior problems have effects on maternal behaviors of affect and authoritarian control. The sample consisted of 297 mothers who have first-and forth-grade children. Multivariate regression analysis revealed that matemal attribution about children’s knowledge for misconduct had positive influence on maternal affect and negative influence on authoritarian control behaviors, and that maternal attribution of expectation negatively influenced the behaviors of authoritarian control. In addition, such background factors as child age, gender, family income, family type, maternal education, and self-esteem were significant predictors for maternal attributions. In regard of mothering behaviors, child age, maternal age, and self-esteem were related to maternal affect, while family type and maternal self-esteem were related to authoritarian control. The findings suggest the importance of matemal attributions in parenting for better child development.

The 60 subjects of this study were 3rd, and 6th grade elementary and undergraduate university students. The instrument of 44 items had two typical and two atypical exemplars from 11 semantic categories. Each subject was exposed individually to the word list and asked to categorize each item. At test, subjects generated five items that came to mind in each category. Data was analyzed by 2-way ANOVA, age (3) $\times$ category of typicality (2). All main effects and the interaction effect between age and typicality were significant. There were no significant differences among age groups on typical lists while significant differences between university and elementary school students (Grades 3 and 6) were found on atypical lists. Thus, the knowledge base might be an important factor in implicit memory.
