In the present study, we investigated development of verb inflections or endings in 3- to 5-year old Korean-speaking children using 28 action verbs for both comprehension and production tasks. For each verb, a l0-second long motion picture and a sheet of paper with three random-ordered color pictures representing 'before, in the middle of, at the end of' the action were generated. A past tense inflection' -et ta,' two present progressive verb endings '-enta' & '-ko itta.' a future tense ending '-elyeko hanta' were tested. In the comprehension task, children were asked to point to a picture correctly representing the tense of a presented verb. In the production task, children were asked to produce a verb with correctly marking the tense of a presented picture. The order of the two tasks were counterbalanced across the children, and the motion pictures were only presented in the first task. Across the ages, the performance accuracies on both comprehension and production tasks were the highest for the past tense marking followed by two present progressive and future tense markings. For each verb endings, the changes of accuracies across ages were analyzed in both tasks. The types of errors for production tasks were also reported.

The present study examined multicultural family children's articulation accuracy and phonological process using Assessment of Phonology and Articulation for Children(APAC), and compared them with normally developing children. The subjects of this study were 24 multicultural family children between ages 3 years, 6 months and 3 years, 11 months. The multicultural family children's articulation accuracy was significantly lower than the normally developing children's. In case of the normally developing children, phonological processes the multicultural family children showed were observed at a younger age and did not appear at the age of the children participating in this study. The Japanese multicultural family children and the non Japanese multicultural family children showed different rate of the changes. This result shows that articulation development in the multicultural family children may be different among them according to the classification and that the children's error patterns are related to their mothers' native language. The results of this study are proposed to be applicable to articulation assessment and treatment.

Numerous investigators have pointed out that the force of the tongue against the teeth within the dental arches is normally compensated for by the action of the musculature of the cheeks and lips, and that the tongue at rest occupies a large part of the oral cavity. The purpose of this study was to estimate the maximum areas of the tongue movement by measuring the inner area of the dental arches of both the maxilla and the mandible. This study was based on the study models of 30 children and 128 adults who had clinically good occlusion. There were 15 male and 15 female children whose ages ranged from four years to seven years and 82 male and 46 female adults whose ages ranged from fifteen years to fifty four years. The obtained results were as follows : 1. The mean of the maximum areas within the primary dental arches of both the maxilla and the mandible were $7.06\pm0.8\textrm{cm}^2, 5.49\pm0.77\textrm{cm}^2$ in male children and $6.82\pm0.98\textrm{cm}^2, 5.28\pm0.80\textrm{cm}^2$ in female children respectively. 2. The mean of the maximum areas within the permanent dental arches of both the maxilla and mandible were $17.01\pm2.38\textrm{cm}^2, 13.57\pm1.57\textrm{cm}^2$ in male and $16.75\pm2.08\textrm{cm}^2, 13.36\pm1.01\textrm{cm}^2$ in female respectively.

The purpose of this study was to develop a "Family Play Therapy Program" using puppets to decrease attachment problems for families with children having attachment problems and to examine its effectiveness. The participants were an experimental group of 16 individuals(8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers) and a control group of 16 individuals (8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers). The experimental group was treated through the Family Play Therapy Program, which involved the use of puppets and was held for twelve sessions twice a week. The changes in the participants were measured in order to examine the effects of the program. The researcher measured children's emotional and behavioral expression(TBP), the mothers' sense of self(Self-Differentiation Scale), personal relationships(ECR-R), and the perception of family functions(ICPS-FFS) both before and after the FPT program and compared their differences. The MIM Rating Scale and Marschak Behavior Rating Scale were administered to examine the interactions between mothers and children, and 1:1 interviews were also conducted. The data thus gathered were used for non-parametric analysis(Mann-Whitney U test and Wilcoxon rank sum test)using SPSS WIN 17.0. The results of this study were as follows: First, the program had a positive effect on children's emotional expression. After the problem were over, negative emotional and behavioral expression in the experimental group decreased. Second, the program had a positive effect on mothers' self-differentiation and personal relationships. Third, the program had a positive effect on changes in the interaction behaviors between the mother and child. Fourth, the program had a partially positive effect on the responses from their group developmental stages, especially on the subscale of both a program for the reinforcement of mothers' emotions and family play program utilizing puppets.

This study was designed to examine the relationships between three distinct dimensions of teacher-child relationship(closeness, conflict, and dependency) and various aspects of children's social competence. The subjects were 101 children at their ages of five to six years old (56 keys, 45 girls) in Jeonju city. The data were collected through preschool teachers by using self-administered questionnaire method. The results showed that teacher-child relationship was significantly associated with their social competence in preschool. Specifically, closeness in children's relationship with their teachers was fouled to be strongly correlated with children's social competence, white conflict between children and their teachers was negatively related with children's social competence. Finally, children's dependency on their Coachers was associated with children's problem behaviors.

Children are not small adults and there is a need to carry out specific trials that cannot be performed in adults. In general, children (minors) are unable to consent but their assent should be obtained using age appropriate information. Institutional Review Board (IRB) need paediatric expertise to balance the benefits and risks of research in children. The lack of consent has implications on the design, analysis and the choice of comparators used in the trials, which should only be performed by trained investigators with paediatric experience. Pain, fear, distress and parental separation should be prevented and minimised when unavoidable. The children requires even more careful review. Children represent a vulnerable population with developmental, physiological and psychological differences from adults, which make age- and development- related research important for their benefit. Finally, criteria for the protection of children in clinical trials therefore need to be laid down. Specific protection should be defined for research performed in children, at all stages and ages.

Of 42 children, 21 in male and 21 in female, whose ages ranged from 2 to 5 years old, the response of young children to their initial series of dental visits was examined. The results were as follows; 1. With continued experience, the child's response improved, indicating desensitization to dental stress. 2. Experience may reduce the general amount of negative response by allowing the child to accurately distinguish between stressful and non-stressful procedures.

This study examined the structural relationships among 4- and 5-year-old children's playfulness, communication skills, and creative characteristics. This research analyzed the direct and indirect influence of child's playfulness on communication skills and creative characteristics. The study subjects were 249 children who attend kindergartens located in the Seoul and Gyeonggi-do area. A survey questionnaire was distributed to the children's mothers and teachers. The sample was analyzed using SPSS 21.0 and AMOS 21.0 program. The parameters were estimated by maximum likelihood method. The significance of indirect effect was tested by bootstrapping at .05 level. The results of this study were: (1) in both ages 4 and 5, playfulness had a direct and positive influence on communication skills, (2) in both ages, communication skills had a direct and positive effect on creative characteristics, and (3) the 5-year-old children's playfulness had a direct effect on creative characteristics, the 4-year-old children's playfulness did not exert direct influence onto creative characteristics. Communication skills 5-year-old children were seen to precipitate a partial mediation effect between playfulness and creative characteristics. At age 4, communication skills played a full mediation variable role between playfulness and creative characteristics. Discussions include suggestions to prosper creative characteristics through enhancing a child's playfulness and communication skills.

The purpose of this study was to examine changes in the rate of occurrence of challenging behaviors in young children according to their increase in age. The study is based on the responses of teachers in child care centers(N=246). They were asked which 38 types of challenging behavior occur most among ages 2, 3, 4, or 5 in young children's classrooms. The major results of this study were as follows. First, the occurrence rates of young children's challenging behaviors were classified into 5 clusters; decreased(Cluster 1, Cluster 2, Cluster 3), maintained(Cluster 4), or increased(Cluster 5) according to increases in their respective ages. Second, the behaviors such as throwing tantrums and biting, evident in Cluster 1, decreased very rapidly from a very high occurrence rate by age 3. The classroom culture maladjustment behaviors such as running aimlessly around the classroom and shouting, apparent in Cluster 2, had decreased rapidly from a high occurrence rate by age 4. The intentional classroom disruptive behaviors such as dropping objects to create noise and the peer culture maladjustment behaviors studied in Cluster 3 decreased gradually from a rate of medium occurrence by age 5. These results revealed the discontinuity which a few young children exhibit. Third, hurting others, observed in Cluster 4 maintained a low occurrence rate from age 2 until age 5. Using inappropriate language and threatening others in Cluster 5 increased gradually from a low occurrence at 2 to a high rate of occurrence at age 5. By carefully examining the change of young children's challenging behaviors on the basis of objective data in terms of the continuity/discontinuity and increased/decreased rate of diverse challenging behaviors, we will be better able help teachers and parents to plan the instruction, prevention and intervention of young children's challenging behaviors.
