The purpose of this study was to investigate the relationship between age, internal state information, and narrative structure. Another purpose was to examine how the kinds of replica play and story props affect the theme of children's narratives. The subjects were 36 4-and 5-year-olds. Children's narratives were audiotaped and analyzed accordmg to narrative structure, themes and internal state factors. The results indicated that 5-year-olds showed well organized narrative structure such as a descriptive narrative and a primary plotted narrative whereas 4-year-old presented no response and a descriptive narrative. Also, 5-year-olds used more internal state information in the narratives than 4-year-olds. The replica figures serve to remind the chiidren of story themes: the children with police props presented negative themes while children with playground props showed positive themes.

The author reviewed various psychological measures of attachment types and variation on developmental stage approaches. Also, the point of reliabilities and validities of the measures were reviewed. SSP and AQS introduced first in infancy. Cassidy-Marvin's attachment type system, Crittenden's PAA, Main & Cassidy's attachment system, Doll play techniques and Family drawing analyses of attachment types introduced secondly for preschooler. IPPA for parent and peer attachment introduced for Childhood/Adolescence. Finally, AAI and ASQ for romantic attachment explained for adulthood.

The purpose of this study is to set the standard items of the garment size for infants. The studied subject consisted of 560 infants from at brith to 12 months of Pusan and Gyeongnam area. The Results from this analysis are as follows; 1. The most significant growths in body dimensions of infants as an month age advanced. Expecially, stature, weight and the items of height and length showed a quite rapid growth, but the items of girth, breadth and depth showed a slow growth. 2. The coefficient of correlation between stature and weight shows high value. The result of interpretation of the extracted components are as follows. It will be more appropriate to use the method of parallerizing with height and weight items rather than with month age in classficating and indicating of size for infant garment and in taking the head girth as basic item of infant for head-gears. Consequently, as the standard items for the classification of clothing constuction of infants, it is advisable to select weight alone or both stature and weight. 3. According to the method of classifying the somatotype by the index of body soundness, the Rohrer.Kaup index on the basis of standard items, weight and stature was divided into somatotype.

This research examined age differences in the way 3-, 4-, 5-year-old children solve scientific problems involving magnetic and nonmagnetic objects. Their scientific process skills and scientific concepts were examined in 1) hypothesis setting, 2) hypothesis verification and 3) hypothesis application. Data was analyzed by one-way and two-way ANOVA and Scheffe. Children's scientific process skill presented differences by age in each phase of problem solving. That is, the scientific concept level demonstrated by 4-year-olds was higher than that of the 3-year-olds. That of the 5-year-olds was higher than the 4-year-olds. In addition, in all age groups, the children showed a higher level of understanding about magnetic and non-magnetic objects in the hypothesis application phase than in the hypothesis setting phase.

Whereas oral ranula is relatively common and presents as a cyst in the mouth, the plunging ranula is rare and manifests itself as a mass in the neck with or without an associated oral lesion. When there is a soft anterior neck swelling without oral swelling, diagnosis is still difficult. In such a case, clinical suspicion may be low and the pathologist may be misled by the histologic appearance. Recognition of the diagnosis of plunging ranula is essential for the correct treatment of these lesions. We report a case of a 4-year-old girl and review the literatures to discuss the differential diagnosis and treatment modalities.

The purpose of this study was to investigate children's acquisition of cardinality in terms of a framework that isolates two cognitive components, analysis of knowledge and control of processing. The subjects were 30 4-and 5- year-olds who were asked to solve three problems that required an understanding of cardinality. The problems were designed to place different demands on these processing components on the tasks than the 4-year-olds and correlastion among scores on the three tasks show that there is no correlation between the tower task assessing control and the two tasks that assessed analysis. The implications of the results are that aspects of symbolic development may be a broadly based process that extends beyond domain-specific boundaries.

The purpose of this study was to analyze the weight measurement tasks according to children's ages and whether 4-to 6-year-old children use proper measurement equipment to measure weight. The study subjects were 105 preschool children: 37,38, and 30 4-, 5-, and 6-year-old children, respectively. The results showed that young children use 3 to 4 strategies. They used a strategy to estimate objects visually on the first step in measurement by direct comparison. On the second step, in measurement by nonstandard unit, they held up objects with one hand or two hands. That is, two strategies were shown in measuring objects with hands in this second step. On the third step, which is measured by standard unit, they used a strategy to choose the equal arm balance out of suggested measurement equipment.

This study investigated the relationship between pretend play and comprehension of pretense by type of stipulated transformation among 2-and 4-year-olds children. Each child participated in pretend play with its mother for 10 minutes and in a stipulated task for comprehension of pretense. There was a significant difference in 2- and 4-year-olds in frequency and level of pretend play, and pretend play behavior was related to comprehension of pretense. Level of pretend play was positively related to comprehension of 'complexity' of stipulated transformations. This showed that there was significant relationship between development of pretend play and ability to comprehend pretense based on physical transformation.

Causal relationships of kindergarteners' phonological awareness and processing to their ability to read words was investigated with the participation of 289 4- to 6-year-old children attending three kindergartens in Busan. Results showed gradual growth in reading ability with age. Children performed best in reading words and poorest in reading low frequency letters. They showed continuous development in skills of syllable deletion, phoneme substitution, phoneme insertion, phonological memory and naming. Discontinuous development was found in counting syllables. Longer syllables were difficult to count, and middle syllables of 3 syllable words were hard to delete. Children had poor perception of final consonants of Consonant-Vowel-Consonant syllables. Children's phonological awareness and processing were latent variables strongly related to ability to read words written in Hangul.

The purpose of this study was to describe and understand the characteristics of morphological, contextual as relational aggression among 4-year old children during free play periods. The ethnographic methods included participants observation of children's play interaction behaviors, field notes, video taping and analysis of transcribed date. The results are as exclusion occurred by group power taking the relational attribute, including direct language, while the other would not be revealed easily other than being in line with real relation. Also as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatrning their friend' and 'withdrawal of friendship'.
