The purpose of this study was to examine structural relationships among directors' coaching leadership, organizational culture, early childhood teachers' empowerment, teacher-efficacy and job satisfaction. The data were collected from 575 early childhood teachers and analyzed with Pearson's correlation and structural equation modelling analysis. The results were as follows: first, directors' coaching leadership was found to have a direct effect on early childhood teachers' job satisfaction and an indirect effect through organizational culture, teachers'empowerment and teacher-efficacy. Second, organizational culture was found to have a direct effect on early childhood teachers' job satisfaction and an indirect effect through teacher-efficacy. Third, early childhood teachers' empowerment was found to have a direct effect on job satisfaction and an indirect effect through teacher-efficacy. Fourth, teachers' teacher efficacy was found to have a direct effect on job satisfaction. Additionally, directors'coaching leadership was found to be the most important variable predicting early childhood teachers' job satisfaction. These results suggest that improving directors'coaching readership, organizational culture, teachers' empowerment, teacher-efficacy could help facilitate early childhood teachers'job satisfaction.

Objective: Sex differences in attachment types are absent during early childhood, but emerge in middle childhood. Prior research has shown that boys classify as more often avoidant than ambivalent. The purpose of this study was to investigate marked sex differences in the distribution of attachment types in middle childhood, especially in boys. Methods: Attachment was assessed with the Separation Anxiety Test in a sample of 208 boys in Grades 3 and 4. Their socioeconomic backgrounds and developmental histories were also collected. Results: The distribution of attachment types was differed from those in early childhood, with insecure boys more often avoidant (31.3%) than ambivalent (7.2%). Insecure-avoidant boys were rated as over 10% compared the global distribution. Conclusion: These results supported the hypothesis of adrenarche in middle childhood. Boys may be changed to have more avoidant types in attachment.

Objective : The purpose of this study was to investigate morphological change at the craniovertebral junction (CVJ) region using computed tomography. Methods : A total of 238 patients were included in this study, and mean age was $47.8{\pm}21.3months$. Spinal canal diameter, Power's ratio, McRae line, antero-posterior C1 ring height, atlantoaxial joint space, C2 growth, epidural space from the dens (M-PB-C2) and longitudinal distance (basion to C2 lower margin, B-C2) were measured. The mean value of each parameter was assessed for individual age groups. The cohorts were then divided into three larger age groups : infancy (I) (${\leq}2years$), very early (VE) childhood (2-5 years) and early (E) childhood ($5{\geq}years$). Results : Spinal canal diameter increased with age; however, this value did not increase with statistical significance after VE age. A significant age-related difference was found for all C2 body and odontoid parameters (p<0.05). Mean McRae line was 8.5, 8, and 7.5 mm in the I, VE, and E groups, respectively. The M-PB-C2 line showed up-and-down dynamic change during early pediatric periods. Conclusion : Expansion of the spinal canal was restricted to the very early childhood period (less than 5 years) in the CVJ region; however, the C2 body and odontoid process increased continuously with age. The above results induced a dynamic change in the M-PB-C2 line. Although C2 longitudinal growth continued with age, the McRae line showed relatively little change.

For the purpose of investigating the etiologic factors of early childhood caries in 18-month old infants which is an important period in pediatric dentistry, 234 infants of 18-month age and their first care-givers (mothers in most cases) who visited Ilsin Christian Hospital in Busan for the baby-care counseling and vaccination were examined. The oral examination was performed on the infants and their care-givers were individually interviewed about various items, and the data was statistically processed to yield the results as follows : 1. The prevalence rate of early childhood caries was 27.4%. 2. The percentage of the eldest child, the education level of the mother and monthly income were revealed lower in caries group infants. 3. The percentage of prolonged breast-feeding and the frequency of daily nursing was higher in early childhood caries group. 4. In early childhood caries group, the between-meal snacks were tend to be provided irregularly without predetermined time, and sugar containing snacks such as chocolates and candies were ranked in higher order whereas the fruits and milks were in lower ranks. 5. In early childhood caries group, the percentage of those performing the oral hygienic care was lower and the timing to start the toothbrushing was comparatively later. From the above results, it can be concluded that prolonged breast-feeding, poor snack habits and lower socioeconomic status act an important role in early childhood caries in 18-month old infants.

The purpose of this research was to identify the importance of social competence in early childhood, age 3 to 5, by examining the relationship between the children's variables such as gender, age, and temperament, with that of their mothers' emotionality, and the social competence. 72 children in the early childhood age bracket were surveyed. Three major findings were established. Firstly, there were no gender differences in relation to social competence. Children's adaptability and social activity were related to their pro-social behavior and the ability to internalize/externalize problems. Secondly, children exhibited pro-social behavior only when their mother's emotional reactivity was positive. hirdly, children's social competence was influenced by individual variables and their mothers' emotionality. Prosocial behavior, a lower ranking domain, was influenced by children's adaptability and mothers' emotional reactivity. The children's ability to internalize problem was influenced by adaptability. In contrast, The ability to externalize problem was influenced by the range of activities they were involved in. Overall, children's social competence was influenced by their age.

The purpose of this study was to research the differences between gender roles and creativity. This study was done based on 178 pre-service teachers who were from the Department of Early Childhood Education in Universities around the Busan area. The researchers have collected statistical data by questioning pre-service teachers about creative thinking tests, creative personality tests, and gender role identification awareness tests. The data was interpreted by the Paerson's Simple Product-moment Correlation Coefficient method, the one-way ANOVA method, and the $Sch\acute{e}ffe$ Post-hoc comparison method. According to this study, the group perceived of high androgyny type group showed the highest level in important factors of creative thinking, such as fluency, elaborateness, ness, and openness. This result meant that the more a pre-service teacher was aware of the identity of gender roles, the more she or he thought creatively. Additionally, the acceptance of authority, an element of the creative personality factor, showed the highest level in a high feminity type group. On the other hand, self confidence, inquisitiveness, and disciplined imagination showed the highest level in a group which perceived the identity of androgyny type roles.

The purpose of this study was to conduct a qualitative analysis of mothers' role experiences during their children's transition from early childhood to middle childhood. Eleven mothers of first-grade elementary school students participated in a group meeting, group interviews and journal writing. The results indicated that mothers described their experiences as a critical first step outwards on the journey to independence. The role experiences of the mothers who participated in this study can be seen from three perspectives: Firstly, as mothers as individuals projecting a mother's worries onto their child and becoming a capable person to help their children adjust to a new school environment, secondly, as mothers as family members experiencing a more authoritarian parenting style and difficulties of co-parenting with their husbands and parents-in-law, and lastly, as mothers as members of the extended family systems experiencing communication difficulties regarding the public education system and feeling uncomfortable with other parents. The findings may be used to develop support programs as well as a channel for interacting with public education bodies and community agencies.
