This study analyzed the pattern of preschool children's abilities based on Project Spectrum and compared the relationship between intelligence domains with working styles of children. Generally, children showed both strengths and weaknesses in specific Spectrum domains, but some children had only strengths and others had only weaknesses without strengths. It appeared that working style does not relate to children's strong domains, but individual disposition was reflected by characteristics of the task. During both individual and group spectrum activities, children with strengths were more "easily engaged in activity", "confident", and "focused" than those without strong intelligence domains. During individual activities, the "reflective" domain showed children with strengths in intelligence domains are more reflective than those without strengths.

In contrast with Zelazo and Frye (1997) who argued that preschool children lack the conscious representation and executive functioning needed to solve problems based on conflicting rules, Bilaystok (1999) identified analysis(representation) and control(selective attention) as components of language processing and has shown that control develops earlier in bilingual than in monolingual children. This study investigated the effects of bilingualism on children's cognitive ability and language development by comparing Korean- Chinese bilingual with Chinese monolingual children in Yanji. Sixty children 3 to 5 years of age in each of the bilingual and the monolingual groups in Yanji, China participated in ths study. Results showed that bilingual were more advanced than monolingual children in solving problems requiring a high level of control, confirming Bialystok's(1999) results.

The study examined the influences of age, empathy and perspective taking ability on altruistic lying in 5 and 6 year old children. Eighty three children answered a question as to whether a protagonist would lie after listening to three vignettes involving altruistic lies. Korean versions of the Affective Situation Test(AST) and cognitive perspective taking task were used to measure children's empathy and perspective taking respectively. The results of the study showed that there were significant differences in altruistic lying by age. Altruistic lie by children was positively related with their age, empathy and perspective taking ability. In particular, age and perspective taking ability are important factors influencing children's altruistic lie in young children in Korea.

This study was conducted to investigate the difference of perception about nutritional problems and food intakes and nutrition knowledge score and realities of nutrition education between parents and preschool teachers. This research can be summarized as follows: there was the statistical difference of perception (${\chi}^2$= 52.451, p = 0.000) about nutritional problem of preschoolers between parents and preschool teachers. Parents (56.4%) and teachers (58.5%) identified eating only what they want as the most common nutritional problem of children, but they had different perception about the other problems. To parents, "No nutritional problem" (16.3%) is the second and "Overindulgence of processed food" (11.1%) is the third problem of preschoolers. To teachers, "Overindulgence of processed food" (23.8%) is the second and "Obesity" (14.3%) is the third problem. The perception on food intakes of preschoolers was statistically different in meats (${\chi}^2$= 8.892, p = 0.030), fish (${\chi}^2$= 32.241, p = 0.000), beans (${\chi}^2$= 14.770, p = 0.005), vegetables (${\chi}^2$= 12.706, p = 0.013), fruits (${\chi}^2$= 14.438, p = 0.006) and milk & dairy products (${\chi}^2$= 28.591, p = 0.000) between parents and preschool teachers. However, nutritional knowledge was not different between parents and preschool teachers. While 96.6% of preschool teachers felt that it was necessary to educate preschoolers, only 41.5% of them said that they fulfilled nutrition education, showing that nutrition education was not adequately carried out on the spot. Therefore providing basic materials through which nutritional management guidance and proper nutrition education for preschoolers can be carried out by investigating and analyzing knowledge on their nutrition and meal guidance activities for preschooler teachers and parents.

Purpose : In order to evaluate the time of disappearance of cytomegalovirus(CMV) IgG antibodies from mothers, and the alteration of the positive rate of CMV IgG antibodies among preschool period children, we investigated the positive rate of CMV antibodies among preschool children. Methods : We studied 391 children who visited the Department of Pediatrics from March, 2001 to February, 2004. We measured the serum CMV IgG of 217 children and the serum CMV IgM of 358 children. Results : The positive rate of CMV IgG antibodies is 83.9 percent(the number of positive IgG children is 182 out of 217). The alteration of the positive rate is 92.9 percent in 0-3 months, 75.0 percent in 4-6 months and the nadir was 20.0 percent in 7-9 months. Then, the positive rate increased to 83.9 percent in 22-24 months. After 22 months, the positive rate was 92.1 percent(the number of positive IgG children was 105 out of 114). The positive rate of CMV IgM antibody by age is 3.3 percent in 0-1 months, 3.6 percent in 1-2 months, 10.5 percent in 2-3 months, 14.3 percent in 3-4 months, 14.3 percent in 4-5 months, and then the results of five children among 148 children were positive. The distribution was one in 22-23 months, one in 25-26 months, one in 27-28 months, one in 28-29 months, one in 40-41 months. We discovered IgM positive children succesively from birth to 5 months, but sporadically after 5 months. Conclusion : The CMV IgG from mothers has decreased since birth and the time of nadir is 7-9 months. But it increases to a mean value of 83.9 percent at 22-24 months because of perinatal or postnatal infections.

The purpose of the study was to investigate the relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. fifty-four children aged 5 and 6 years and their mothers were observed and videotaped in a strange situation. Children were interviewed in order to assess interpersonal cognitive problem solving skill. teachers rated children's social development using modified ISCE(Iowa Social Competency Scale : Preschool Forma). The results showed that there were significant relationships of maternal attachment, social competence and interpersonal cognitive problem-solving skill. children of the secure attachment to mothers were greater social activator, cooperative, alternative solution thought and consequential thought. In contrast, children of insecure attachment to mother were less social activator and cooperative, and more hypersensitive and apprehensive. Children's social competence was related to the interpersonal cognitive problem-solving skill.

This study investigated preschool children's script knowledge according to task situation and socioeconomic status. Subjects were seventy-eight 5-year-old children (38 low- and 40 middle-income children; 36 boys and 42 girls) recruited from three day-care centers in Seoul. Each child participated in the script knowledge assessment session. Assessment of script knowledge consisted of a picture-recognition and picture-sequencing task. Statistical methods used for data analysis were means, standard deviations, repeated measures ANOVA. Results showed that children's script knowledge scores were higher in familiar task situation than in unfamiliar task situation. Furthermore, middle-income children had higher scores of script knowledge than low-income children. Findings of this study indicate that there is the difference of script knowledge between low- and middle-income preschoolers.
