This study was to find out children's Negotiation Levels(NLs) according to their age and gender. The subjects for this study were 143 children of 7, 9, 12 years. Two children dyads participated in the experimental play situation with Rokenbok Electronic Toy Systems. The NLs in children's interactive dialogue & actions were scored with Stone, Robinson & Taylor(1980)'s 'Negotiation of Task Completion Coding Manual'. They were coded into Level 0(no interaction), Level l(one way interaction), Level 2(reciprocally interaction), Level 3(mutual or cooperative interaction). The results were as follows; 1) 12-year-old children negotiated with higher level than 7-and 9-year old children 2) Boys' NLs average were higher than girls'. These results imply that 1) the fluctuation of NLs in childhood, especially around 10 years, should be interpreted carefully, 2) various measuring kits for negotiation should be developed considering children's characteristics, such as age, gender etc.

The purpose of this study was to investigate developmental tendencies and age-related differences in the relationship between children's cognitive and emotional perspective-taking ability. The subjects were 4-year-old (N=60), 6-year-old (N=60) and 8-year-old (N=60) children. In each group, there were an equal number of boys and girls. Feshbach & Roe's child perspective-taking ability test was modified for this study. The test included four facial expression cards and six different stories inducing three types of emotion: happy, sad and angry. This experiment consisted of a 3 (age) by 3 (emotional stories: happy, sad and angry) factorial design. The dependent measures were two response types: emotional and cognitive perspective-taking ability. The results showed that both cognitive and emotional perspective-taking ability increased with age. Happy emotional perspective-taking ability developed earlier than sad and angry perspective-taking ability. The correlation between cognitive and emotional perspective-taking ability increased with age.

This study investigated differences in the topic performance of 3-year-old Korean and American children. Sixteen mother and child dyads (8 Americans and 8 Koreans) were tape-recorded during naturally occurring conversations. The cape-recorded data were transcribed on the observational chechlist by Kertoy Vetter(1995). Korean children engaged in topic performance nearly twice as often as American children. Korean children engaged in topic termination/initiation and continuation more often than American children. Also, Korean children engaged in topic collaboration and incorporation more often than American children, but there was no difference in off-topic.

Objectives The purpose of this study was to find out the characteristics of children patients who had been treated in the Oriental Medical Hospital due to traffic accidents. Methods The study was carried out with 121 children patients who visited the Oriental Medical Hospital from April 2011 to March 2012 and was analyzed by reviewing the patients' charts. Results In the distribution of sex the ratio between boys and girls were similar, but regarding the age, 0~6 year-old group was more than that of 7~15 year-old group. In the traffic accident patterns, 87.6% of the entire children patients were injured by car crash. The highest type in the collision between cars was rear-ending impact. The most patients (48.8%) visited our hospital for oriental medical treatment in less than 3 days after the traffic accident. The number of the first visitors in the Oriental Medical Hospital were 77 (63.6%) and those who visited other western hospitals before and were 44 (36.4%). The most frequent duration of admission and treatment in OPD was less than 7 days. Sleeping disorders (37.1%) were diagnosed the highest in 0~6 year-old group and C-spine sprain (49.0%) was diagnosed the highest at 0~7 years-old group. Herb medications were prescribed to relieve anxiety for 0~6 year-old group and for 7~15 year-old group, those were prescribed to activate blood eliminating phlegm and to normalize Qi flow. The highest effective treatment period was less than 7 days. Conclusions This data suggested that the oriental medical care could be more effective in treating children victims of traffic accidents by confirming many different symptoms depending on the age.

Attachment behaviors were measured with the Preschool Strange Situation(Cassidy and Marvin, 1992) and classified as secure, avoidant, dependent, or disorganized. Narrative representations of mothers by Children were obtained by video taped interviews using the MacArthur Story-Stem Battery and coded by the MacArthur Narrative Working Group(1997) system. Data were analyzed with descriptive statistics and t test. Results were that children in the secure group showed more positive representations of their mothers, more prosocial story themes, had higher scores in theme coherence and showed more positive emotional expression than those in the insecure group. The attachment behaviors of the 4 groups(A, B, C, D) were closely correlated with the attachment representations shown in MSSB.

Objectives : The purpose of the study is to investigate the significant(SiC) index of the 12 year old children's permanent teeth caries experience. A total of 428 children aged 12 years old were recruited from metropolitan city(215 children) and rural area(213 children) in this study. SiC index was obtained from DMFT index. Data were analyzed by gender, region, and DMFT. Methods : DMFT index and Sic index were analyzed and compared by pit and sealant fissure treatment, dental caries, gender, and areas. A total of 428 children aged 12 years old were recruited from metropolitan city(215 children) and rural area(213 children) in this study. Results : Boy students(6.73) tended to have a higher SiC index than girl students(7.84). There were significant differences(p<0.05). DMFT index in urban area was 2.59, and that in rural area was 3.35. In SiC index, rural children showed a higher index(7.77) than urban children(6.72).There existed a significance between DMFT index and SiC index(p<0.05). Conclusions : It is important to educate and to develop the oral disease prevention program for the high risk group children. This study showed the relationship between DMFT index and SiC index in 12 year old children in urban and rural areas.

A nutrition survey of 152 children , in the kindergarten attached to a proivate elimentary school of Pusan, was undertaken between Dec. 1 and Dec.14, 1993, to investigate dietary intake and nutrition status. The results are summarized as follows. 1) Compared with the Korean child development standard, their development conditions showed 113.1% , 102.2% , 103.3%, 101.75 in weight, height, head and chest, respectively. 2) By the standard of WLI(Weight Length Index) , proper to the children between age 4 and 6 , there proved to be 25% overweight and 4% obesity, 25% overweight and 19% obesity , 28 overweight and 26% obesity in 4-year-old, 5 year-old, and 6 -year-old children, respectively. 3) The children between age 4 and 6 averaged 37.6% in hematocrit and 12.4-12.8 5 in hemoglobin. these values were higher than those of the Korea child development standard. but the numbers of erythocyte, leucocyte and platelets were normal . Only a single child was considered suffering from aenmia . The 8% of them were over 200mg/이 in cholesterol, dangerously approaching the atherosclerosis. The 31% averaged 120mg/이 in triglyceride . And the 6% proved 100mg/이 in blood glucose when hung교. So it came out that not a few children had some factors dangers to diabetes, atherosclerosis and heart diseases : complications arising from obesity. 4) The intake of nutrients , except the 4-year-old children , ranged 108.4% to 2665 from the recommended value. The rates of carbohydrate, fat and protein to be much correlation among total intake of nutrients, development , results of blood test and WLI. The degree of obesity was proportionate to the intake of nutrients.

The present study investigated the sleep patterns 1-to 3-year-old children and examined whether their sleep patterns would predict their early adjustment to daycare centers. The participants were 239 young children attending daycare centers in Seoul. The data on children's sleep patterns were collected by parent report. Children's adjustment to daycare was assessed by daycare providers' reports. The data were analyzed by means of Chi-square test, t-test, Pearson's correlation, ANOVA and discriminant analysis. The results were as follows: Children from dual-earner families had shorter nocturnal sleep duration than those from single-earner families. There was no significant relation between daytime sleep duration and sleep-onset time at night. It was found that children who go to bed earlier were more likely to get sufficient sleep without nocturnal wakefulness. Age and total sleep duration were seen to be significant variables when it came to discriminating between the adjustment versus maladjustment groups.
