This study composed spatial cognition tasks within the system of geometric area to study children's spatial cognition development systematically. It surveyed children's execution of direction, rotation, symmetry, conjugation, and part/whole cognition tasks. A spatial geometry cognition task set (consisting of total 27 sub-tasks) was presented to 60 children (20 each in groups of 3-, 4-, and 5-year-old) in order to confirm how children's execution of spatial geometry cognition changed depending on children's age and sex as well as if the execution of the spatial geometry cognition showed a difference after each task area. As a result, the execution of the whole direction task and the part/whole task gradually increased between age 3 and age 5. The execution of the whole rotation task, whole symmetry task, and whole conjugation task rapidly increased between age 3 and age 4. Significant sexual difference did not appear in the execution of spatial geometry cognition tasks. The execution of the conjugation and part/whole task was high in each task area, and the execution of the direction, rotation, and symmetry task was relatively low. In addition, the difference of task execution appeared in the sub-tasks of direction, symmetry, and conjugation areas. This result suggests the theoretical discussion possibility of children's spatial geometry cognition development. In addition, the empirical results of this study can be applied to child education plans and activity compositions appropriate for child development.

The purpose of this study is to compare the complexity of language level between verbally-precocious and typically-developing children from 2 to 3 years-old. Participants were 15 children classified as verbally-precocious were scored at the mean 56.85(expressive language) and 88.82(receptive language), and another 15 children classified as typically developing did at the mean 33.51(expressive language) and 58.01(receptive language) on MCDI-K. Each child's spontaneous utterances in interaction with her caregiver were collected at three different times with 6 months interval. All of the utterances were transcribed and analyzed for the use of MLU and lexical diversity by using KCLA. Summarizing the overall results, verbally-precocious children had significantly higher language abilities than typically-developing children at each time, and there were significant differences between two groups in syntactic and semantic language development, showing that verbally-precocious children indicated distinctive MLU and lexical diversity. These results suggest a high degree of stability in precocious verbal status, with variations in language complexity during conversations contributing to later differences in their language ability.

Background: Atopic dermatitis one of the most common chronic skin diseases, is caused by various environmental and genetic factors. Methods: A total of 2609 healthy newborns who were enrolled in the COCOA study (COCOA) from 2008 to 2015 were surveyed for indoor environmental exposure to fungi during gestation and then diagnosed postnatally for atopic dermatitis. The fungi collected during the gestation of 20 normal subjects and 20 infants that developed atopic dermatitis were identified using Illumina's MiSeq platform and analyzed for their diversity and species. Results: A total of 2,609 respondents were surveyed (52.8% male and 47.2% female) Children, 1, 2, and 3 years old diagnosed with atopic dermatitis comprised 15.2%, 15.7%, and 14.1% of the respondents, respectively. The prevalence of exposure to mold during gestation was 1.46 (95% CI, 1.05-2.04) and 1.52 (95% CI, 0.95-2.43), in the first and third years after birth, respectively. One-year-old children with atopic dermatitis and no fungal markers detected in the bathroom environment during gestation accounted for less than 5% (aOR, 1.51; 95%CI, 0.96-2.38) and in the group less than 5 ~ 30% (aOR, 2.21; 95%CI, 1.00-4.89), 3-year-old children had an increased prevalence of atopic dermatitis of more than 30% (aOR, 9.48, 95%CI 1.42-63.13). Conclusions: Exposure to indoor fungi during gestation and infancy is associated with the development of atopic dermatitis in children. The phyla and genera of the fungi in the indoor house dust differed during gestation. This suggests that exposure to indoor fungi during gestation may be associated with the development of atopic dermatitis in children. Future research will be necessary to establish the underlying mechanisms.

Many parents recognize the importance of social development during early childhood but they feel difficulty in helping their children develop socially. Recently, many researchers have suggested that maternal cognition is an important factor on their parenting behavior and children's development. Thus, this study attempted to investigate the mother's perception and attribution of parenting efficacy for children's social development. Total 247 mothers of three to five year-old children reported self-questionnaire consisting of Melson, Ladd, & Hsu(l993)'s Perceived Difficulty at Parenting Tasks, Criniic & Greenberg(1990)'s Parenting Daily Hassles and Abdin(1990)'s Parenting Alliance Inventory. Also, 82 of the subject's children were individually tested with McGinnis & Goldstein(1990)'s Skill Situations Measure. The major results were as follows: 1) Mothers' parenting efficacy for children's social development was significantly related with child's age, mother's education and the father's cooperation of parenting. 2) Mothers' perceived parenting efficacy was significantly correlated with some dimension of the child's actual social skill (i.e., maintenance of peer relation). 3) Mothers of young children were more likely to attribute to their children for their parenting efficacy than those of old children. 4) Mothers were more likely attribute to their children than themselves when they perceive parenting difficult. 5) Mothers who perceive parenting easy and attributed it to their children had less parenting stress than those of attributing it to themselves.

This study examined relationships between parenting attitudes and young children's injury risk behavior by age and gender. Subjects were 161 3- to 5-year old children and their parents. Instruments were the revised Parenting Attitudes Questionnaire (Reitman et al., 2002) and the Injury Behavior Checklist (Speltz et al., 1990). Data were analyzed by MANOV A. Results were that: 1) Fathers were more permissive to daughters; mothers were more permissive to younger children. 2) Older children had more injury risk behaviors than younger children; boys engaged in more injury risk behaviors than girls. 3) Fathers' authoritarian and mothers' permissive attitudes were positively related to children's injury risk behavior, respectively. Fathers' and mothers' authoritative attitudes were negatively related to children's injury risk behavior.

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 purpose of this study is to develop art activities using famous painting parodies in hopes of enhancing the creativity of 5-year old children. A total of 11 program activities were developed consisting of a preliminary activity (understanding the notion and ideas behind parody), introduction (view and analysis of famous paintings), development (theme selection, idea construction, and parody production), and conclusion (view and review of parody). Participants were 50 (24 in the experimental group and 26 in the comparative group) 5-year old children from a kindergarten located in G city. TTCT of Creative Thinking (TTCT: Figure A and B) was used as a research tool, and the listening abilities paintings test tool was applied to teachers of the groups. First, excluding accuracy, which is considered to be an unimportant factor in determining one's creativity, results showed positive effects on fluency, originality, abstractness, and persistence. Second, the program also showed positive effects on children's overall ability in appreciation of paintings as well as the sub factors including observation and expression, understanding painter's intention, atmosphere, materials and techniques, art elements, and attitude towards art piece.

Atypical hemolytic uremic syndrome (aHUS), a rare form of thrombotic microangiopathy, is distinguished from the typical form by the absence of a preceding verotoxin-producing Escherichia coli infection. Notably, aHUS occurs in association with genetic or acquired disorders causing dysregulation of the alternative complement pathway. Patients with aHUS may show the presence of anti-complement factor H (CFH) autoantibodies. This acquired form of aHUS (antiCFH-aHUS) primarily affects children aged 9-13 years. We report a case of a 13-year-old Lao girl with clinical features of aHUS (most likely anti-CFH-aHUS). The initial presentation of the patient met the classical clinical triad of thrombotic microangiopathy (microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury) without preceding diarrheal illness. Low serum levels of complement 3 and normal levels of complement 4 indicated abnormal activation of the alternative complement pathway. Plasma infusion and high-dose corticosteroid therapy resulted in improvement of the renal function and hematological profile, although the patient subsequently died of infectious complications. This is the first case report that describes aHUS (possibly anti-CFH-aHUS) in Laos.

This study explores the types of daily routines in child care centers based on the time planned for indoor free choice activities, outdoor activities, group activities and nap/rest. The daily routine plans of 63 classes of 0 to 2-year-olds and 51 classes of 3 to 5-year-olds were cluster analyzed. Also, openness and closeness of child care programs as well as the most participated indoor/outdoor activities were examined using questionnaires developed for teachers. The results were as follows: First, teachers planned the most time for free play choice activity and comparatively less time for outdoor play during the day. Time for rest and naps were planned more for 0-2 year-olds whereas group activities were planned more for the 3-5 year-olds. Second, 3 daily routine types were found in the daily plans of child care centers, such as "Low-Activity Oriented," "Free Choice Activity Oriented" and "Group Activity Oriented" in 0 to 2-year-old classes and 3 to 5-year-old classes. Also, "Group Activity Oriented" type in 0 to 2-year-old classes showed more "closed" child care programs than the "Free Choice Activity Oriented" type. However, no difference was shown among the 3 types of daily routines in the openness and closeness of 3 to 5-year-old child care programs. Finally, all children, regardless of the types of daily routine, participated most in block activity and role play indoors and fixed-play equipment, sand play and free play outdoors.

This study was carried out to reveal Hangul acquisition processes in Korean-Chinese children who grow in a horizontal bilingual environment. In this experiment Grapheme substitution/deletion tasks and sensible/non-sensible Kulja reading tasks were administered to 3-, 4-, 5- and 6-year-old Korean-Chinese children growing up in a bilingual environment. Results were that Korean-Chinese children showed similar patterns of Hangul acquisition processes to Korean children but acquired grapheme-phoneme(G-P) correspondence earlier than Korean children. Hangul acquisition rates were 41.7%, 45.7%, 53% and 92.7% at age 3, 4, 5 and 6, respectively. Both Korean-Chinese and Korean children showed higher sensitivity for the final consonant than for the initial and middle consonants. Correlation between phoneme perception and reading was only significant among 6-year-olds in non-sensible Kulja reading tasks. Training in transforming ideographic Chinese to a phonetic system could effect early acquisition of G-P correspondence in Korean-Chinese children.
