This study investigated the relationship between types of attachment and social adaptation of kindergarten children. Subjects were 108 3-year-old children, their mothers, and their teachers. Results showed that children securely attached to both mother and teacher adapted better than children who were insecurely attached to both mother and teacher. Children who were securely attached to mother but insecurely attached to teacher, and children who were insecurely attached to mother but securely attached to teacher adapted better than children who were insecurely attached to both mother and teacher. This study suggests that the quality of child-mother or child-teacher attachment affects children's social adaptation with the passage of time in kindergarten.

The purposes of this study were to examine the correlations of children's competencies perceived by fathers and mothers, and to investigate differences of children's competencies in relations to characters of the children and that of the parents. The subjects were 225 pairs of father-mother of 7 and of 12 year old children in Daejon. The major findings were as follows. (1) Children's competencies perceived by fathers and mothers were positively correlated with each other. (2) The gender of child affected much on father-perceived esthetic and musical competencies, and on mother-perceived responsible, intellectual, esthetic, and musical competencies. Child's age also had a great effect on father- and mother-perceived esthetic competencies of child. (3) There were no significant differences in children's competencies in relations to characters of parents except in father-perceived responsible competence by fathers' age and in intellectual competencies by income, and in mother-perceived social competences by mothers' job.

This study examined the effect of parenting style on children's prosocial behavior. Children's prosocial behaviors were examined by 3 factors : adaptation to school life, relationships with others, and ability to control emotions. Subjects were 195 three-, four-, and five-year-old children and their parents. Children's prosocial behavior differed as a function of children's age but not gender. Children's relationships with others among the prosocial behaviors showed a statistically significant difference by mother's autonomous parenting style. Unexpectedly, children's prosocial behaviors did not vary according to fathers' parenting style.

Occupant protection performance in frontal crashes has been developed and assessed for mainly front seat occupants over many years, and in recent years protection of rear seat occupants has also been extensively discussed. Unlike the front seats, the rear seats are often occupied by children seated in rear-facing or forward - facing child restraint systems, or booster seats. In the ENCAP, child occupant protection assessments using 18-month-old(P1.5) and 3-year-old(P3) test dummies in the rear seat have already been changed to new type of 18-month-old (Q1.5)and 3-year-old(Q3) test dummies. In addition, ENCAP are scheduled with the development and introduction of test dummies of 6-year-old (Q6) and 10.5-year-old children(Q10) starting 2016. In KNCAP, Q6 and Q10 child dummies will be introduced in 2017 as well. Automobile manufacturers need to develop safety performance for new child dummies closely. In this paper, we focused on Q6 and Q10 child dummies sitting in child restraint system. Offset frontal crash tests were conducted using two types of test dummies, Q6 and Q10 child dummies, positioned in the rear seat. Q6 and Q10 were used to compare dummy kinematics in rear seating positions between Q6 behind the driver's seat and Q10 behind the front passenger's seat. The full vehicle sled test results of both dummies were conducted with different restraint systems. It showed that several injury and image data was collected as the result of the full vehicle sled test. Based on the results of these investigations, this paper describes which factor is most important and combination is the best performance when evaluating rear seat occupant protection for Q6 and Q10 child dummies.

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 aims of this study were to investigate the relationships among mothers' emotion expression, preschool children's temperament, and preschool children's emotion regulation. The participants in this study were 75 5-year-old children from five child-care centers located in Seoul. The collected data were analyzed using simple regression and hierarchical multiple regression. The major findings were as follows. First, mothers' positive emotion expression had a positive influence on children's effortful control, and mothers' negative emotion expression had a positive influence on children's negative affect. Second, mothers' positive emotion expression had a positive influence on children's emotion regulation, while mothers' negative emotion expression had a negative influence on children's emotion regulation. Last, the effect of mothers' positive emotion expression on children's emotion regulation was fully mediated by children's effortful control. Also, the effect of mothers' negative emotion expression on children's emotion regulation was partially mediated by children's negative affect. These results suggest that mothers' emotion expression and children's temperament may predict children's emotion regulation.

Coda in the word-medial position plays an important role in acquisition of our speech. Accuracy of the coda in the word-medial position is important as a diagnostic indicator since it has a close relationship with degrees of disorder. Coda in the word-medial position only appears in condition of connecting two vowels and the sequence causes diverse phonological processes to happen. The coda in the word-medial position differs in production difficulty by the initial sound in the sequence. Accordingly, this study aims to examine the tendency of producing a coda in the word-medial position with consideration of an optional phonological process in spontaneous speech of three and four year old children. Data was collected from 24 children (four groups by age) without speech and language delay. The results of the study are as follows: 1) Sonorant coda in the word-medial position showed a high production frequency in manner of articulation, and alveolar in place of articulation. When the coda in the word-medial position is connected to an initial sound in the same place of articulation, it revealed a high frequency of production. 2) The coda in word-medial position followed by an initial alveolar stop revealed a high error rate. Error patterns showed regressive assimilation predominantly. 3) The order of difficulty that Children had producing codas in the word-medial position was $/k^{\neg}/$, $/p^{\neg}/$, /m/, /n/, /ŋ/ and /l/. Those results suggest that in targeting coda in the word-medial position for evaluation, we should consider optional phonological process as well as the following initial sound. Further studies would be necessary which codas in the word-medial position will be used for therapeutic purpose.

The purpose of the present research was to study the self-regulation of the child during mother child interaction. That is. this study focused on how mothers regulated children's problem solving efforts before children began to function as independent agents capable of self-regulation. The emphasis was on the "regulation-by-others" that preceded "self-regulation". The subjects of this study were 30 mother-child dyads. The dyads were divided into 3 groups of 10 dyads each on the basis of the child's age (2, 3, and 4 years of age). The instrument used for this study was the "truck puzzle" devised by Wertsch, McNamee, Mclane and Budwig (1980). The problem solving task in this study required the dyad to make a puzzle in accordance with the model puzzle. The interaction of 30 mother-child dyads was observed and analyzed flH verbal and non-verbal behavior used by the mother to regulate the child's behavior. One-way ANOVA, Scheffe post hoc comparision and Spearman's rank-difference correlation were used for the statistical analysis of the data. The results revealed that there were significant age trends in regulation-by-others and self regulation in joint cognitive activity; that is, there were developmental transitions from regulation by-others to self-regulation in connection with crucial strategic behavior (looking at the model). Significant differences were found in mothers' interventions after children's gaze at the model in joint cognitive activity; that is, the mean proportion of mothers' intervention for the 2-year-old group was the highest and that of the 4-year-old group was the lowest. There were no significant age-related differences in mothers' use of referential perspectives in joint cognitive activity. Children's regulation- by-others increased and children's self-regulation decreased in proportion to mothers' use of referential perspectives.
