Domains are the building blocks of proteins. Exon shuffling is an important mechanism accounting for combination of a limited repertoire of protein domains in the evolution of multicellular species. A relative excess of domains encoded by symmetric exons in metazoan phyla has been presented as evidence of exon shuffling, and symmetric domains can be divided into old and new domains by determining the ages of the domains. In this report, we compare the spread, versatility, and subcellular localization of old and new domains by analyzing eight metazoan genomes and their respective annotated proteomes. We found that new domains have been expanding as multicellular organisms evolved, and this expansion was principally because of increases in class 1-1 domains amongst several classes of domain families. We also found that younger domains have been expanding in membranes and secreted proteins along with multi-cellular organism evolution. In contrast, old domains are located mainly in nuclear and cytoplasmic proteins. We conclude that the increasing mobility and versatility of new domains, in contrast to old domains, plays a significant role in metazoan evolution, facilitating the creation of secreted and transmembrane multidomain proteins unique to metazoa.

The purpose of this study was to examine mothers' ideal and actual parenting behaviors toward their infants in three parenting domains; social, didactic, and limit setting. A total of 264 mothers of young children under age three from Seoul, Korea completed Parental Style Questionnaires (PSQ). Mothers' self report on their ideal and actual parenting were explored as a function of child sex, age, and birth order. As expected, there were significant differences between mothers' ideal and actual behaviors in all three parenting domains: Mothers' ideal behaviors such as social interaction, didactic interaction and limit setting were higher than those of their actual behaviors. For mothers' ideal parenting, results revealed neither significant main effects nor interaction effects. However, the Parenting Domain x Birth-Order 2-way interaction and the Parenting Domain x Child Age 2-way interaction were significant for mothers' actual behaviors. Specifically, mothers reported more social and didactic behaviors with their first-born than later born children, but not for limit setting behavior. It was also found that higher limit setting behaviors were apparent for their 2- and 3-year-old than 1-year old children whereas lower social interactions were found for 3-year-old than for 1-year-old. In light of universality and uniqueness, mothers' parenting behavior toward young children has been discussed.

Objective: This study investigated 5-year-old children's developmental levels for creative and social personalities according to gender, and whether participation in STEAM-based unplugged robotic activities can improve their creative and social personalities. Methods: Participants were 5-year-old children (N=125) from 11 child care centers. The experimental group included 29 boys and 24 girls enrolled in classrooms that implemented an unplugged activities curriculum over five weeks. The control group consisted of 38 boys and 34 girls. Data were analyzed using a t-test and analysis of covariance, and Hedges' g was used to measure effect size. Results: First, the participating children's mean scores on creative and social personalities were 3.20 and 3.53 on a 5-point Likert scale, respectively. Girls scored higher than boys in sensitivity-various interests and imagination-playfulness domains of creative personality and all three domains of social personality. Second, children in the experimental group showed improvement in all domains of social personality and the effect size was large. They also improved in three domains (openness-humor, imagination-playfulness, independency-immersion) of creative personality, although the effect size was small. Conclusion/Implications: The results imply that implementing a robotics curriculum with unplugged play activities in early childhood classrooms contributes to 5-year-old children's development of creative and social personalities.

The purpose of this study was to investigate developmental of young children's musical abilityes and musical conservation concepts. Two kinds of test were administered to 117 children aged 5-to 7-year-old. The musical ability test consisted of 30 tape-recorded questions regarding 5 musical ability domains, while the musical conservation test consisted of 17 questions regarding 4 musical conservation concept domains. The major findings of the study were as follows: 1)there was a significant difference in young children's musical abilities according to their sex and age. Girls developed their musical abilities better than boys did. Older children noticeable improved their musical abilities, especially, in such three domains as listening musical and rhythmic activities and playing musical instruments. 2)There was a significant difference in young children's musical conservation concepts according to their age, but not according to their sex. Older children improved musical conservation concepts specifically, in rhythm ,number of notes and duration conservation concepts. 3) the results of stepwise multiple regression analysis indicated that the most influence in variable on the musical conservation concepts was musical ability, then followed by children's age and sex. Some suggestions for future research and for the ways to increase musical abilities were discussed.

The purpose of this study was to investigate the gender difference of relationships between the self-esteem and physical and mental health of adolescents. The sample were consisted of 410 adolescents, 202 boys and 208 girls in two urban city of Korea and the mean age was 17.4 years old. The instruments used in this study were Hare Self-Esteem Scale(Hare, 1985) and School Health Efficacy Questionnaire(Froman & Owen, 1991) which is consisted of both physical and mental health. The results showed that there was no gender difference in self-esteem of adolescents. However, the school domain of self-esteem was related to physical health of boys, and both the family domain and the school domain of self-esteem were related to physical health of girls. And both the school domain and the peer domain of self-esteem were positively related to mental health of boys, and all domains of self-esteem(peer, school, and family) were positively related to mental health of girls. In conclusion, there was not gender difference in degree of self-esteem, but there were gender difference in specific domains of self-esteem related with physical and mental health in adolescents.

The teacher's role scale for improving young children's creativity is designed for both teacher self-rating and observer rating. Content validity was determined by 5 experts who defined the domains of specific content. Construct validity was obtained by the self-ratings of 404 teachers of 3- to 5-year-old children. Five factors using 38 items of the original 59 were found to be related to the teacher's role in improving young children's creativity. The factors were Indulgence and Perseverance, Flexibility, Originality, Elaboration, and Fluency. Convergent validity was confirmed by positive correlations of the Teacher's Role Scale with the Teacher's Creativity Test of the Korean Institute for Research in the Behavioral Sciences. For internal consistency, Cronbach ${\alpha}$ of the 5 factors ranged from .74 to .88. Test-retest reliability coefficientents ranged from .653 to .838. These results confirm the Scale as a valid and reliable measure of the teacher's role in improving the creativity of young children.
