This study examines how literary experiences cultivate environmental sensitivity. In this study we have 3 children(6th graders) to experience 3 selected literary works. The experience of 3 children focusing on characters is divided into 'sympathy', 'identification' and 'hostility' by empathy types. In literary experiences, children naturally support the values pursued by main characters. The experience focusing on plot events is consists of 'sympathy' and 'advice'. The children agreed with the way how the characters solved environmental issues while involved in the events by offering advice to characters whose actions they did not agree to. The experience focusing on topics is divided into 'assimilation' and 'reflection'. The children experienced the assimilation process. Furthermore, they reflected on new environmental issues. This result suggests literary experience subserve children to reflect value through empathy and cultivate their intention toward pro-environmental behavior by generating environmental sensitivity.

Purpose: This study aimed to evaluate the autonomic imbalance in syncope by comparing the baseline heart rate variability (HRV) between healthy children and those with vasovagal syncope. Methods: To characterize the autonomic profile in children experiencing vasovagal syncope, we evaluated the HRV of 23 patients aged 7-18 years and 20 healthy children. These children were divided into preadolescent (<12 years) and adolescent groups. The following time-domain indices were calculated: root mean square of the successive differences (RMSSD); standard deviation of all average R-R intervals (SDNN); and frequency domain indices including high frequency (HF), low frequency (LF), normalized high frequency, normalized low frequency, and low frequency to high frequency ratio (LF/HF). Results: HRV values were significantly different between healthy children and those with syncope. Student t test indicated significantly higher SNDD values (60.46 ms vs. 37.42 ms, P =0.003) and RMSSD (57.90 ms vs. 26.92 ms, P=0.000) in the patient group than in the control group. In the patient group, RMSSD (80.41 ms vs. 45.89 ms, P =0.015) and normalized HF (61.18 ms vs. 43.19 ms, P =0.022) were significantly higher in adolescents, whereas normalized LF (38.81 ms vs. 56.76 ms, P =0.022) and LF/HF ratio (0.76 vs. 1.89, P =0.041) were significantly lower in adolescents. In contrast, the control group did not have significant differences in HRV values between adolescents and preadolescents. Conclusion: The results of this study indicated that children with syncope had a decreased sympathetic tone and increased vagal tone compared to healthy children. Additionally, more severe autonomic imbalances possibly occur in adolescents than in preadolescents.

Protein malnutrition of children is one of the most serious nutritional deficiencies in developing country. Urea nitrogen excretion in ureotelic animals is the function most sensitive to dietary protein. The 24 hours excretion of creatinine in the urine of a given subject is remarkably constant from day to day. The creatinine excretion of different individuals of the same age and sex is also quite constant. Low ratios of urinary urea to creatinine are found children low protein intake. The foregiving world-wide investigations indicate that the urea nitrogen/creatinine ratios seems to be a good biochemical indicator to distinguish among group with different levels of protein intake. The purpose of this study is to evluate an indicator of protein intake on the elementary school children ranged from 6 to 8 years of age living in rural and urban areas. Each child measured for height and weight of body. weight measured by means of a plate from scale and height by a vertical measuring rod. Biochemical test were taken from a finger-tip and urine. Hemoglobin level in the blood was measured by cyanomethemoglobin method. From the urine samples, urea nitrogen and urea creatinie were determined by Folin-Wu method and: calculate the ratio. The following result were obtained: 1) Mean of the body weight and height in urban children(Seoul) was higher and heavier than rural children(Kyunggi, Kangwon). And 12% of boys, 18% of girls in Kyunggi and 25% of boys, 22% of girls in Kangwon area weight less than 80% of Korean Physical Standard weight level. 2) The mean hemoglobin values of boys and girls in Seoul are children were 13. 3g/100ml, 13.1g/100ml and the mean of hemoglobin values in Kyunggi 12.9g/100ml of boys, 12.4g/100ml of girls, and 12.4g/100ml of boys, 12.9g/100ml of girls in Kangwon children. It is found that 22% to 24% children inrural area (Kyunggi, Kangwon) had hemoglobin level less than 12g/100ml which means anemia. 3) The mean of hematocrit level of Seoul, boys and girls children were 33.5%, 34.1% and 33.4%, 33.1%, in Kyunggi area and 33.1%, 32.9% in Kangwon area. 4) Urea nitrogen/creatinine ratios in Seoul children were 9. 0, 10. 0 of boys and girls, the ratio were 8.2, 8.0 in Kyunggi boys and girls children, and 7.5 and 7.4 in Kangwon boys, girls children. Low-income rural and upper-income urban background large differences between two groups in the urea nitrogen/creatinine ratio(Seoul: Kangwon in male, female children. p<0.05, p<0.001). The urea nitrogen/creatinine ratio definetly seems to be a good indicator of the quantity of the protein intake. However, whether or not it is an indicator of the quality of the ingested protein ramains to be seen.

Background: Lipid accumulation product (LAP) is associated with the presence and severity of nonalcoholic fatty liver disease (NAFLD) in adults. Purpose: Here we evaluated the ability of LAP to predict NAFLD in obese children. Methods: Eighty obese children (38 girls; age 6-18 years) were included. Anthropometric measurements and biochemical values were obtained from the patients' medical records. LAP was calculated as [waist circumference (WC) (cm) - 58]×triglycerides (mmol/L) in girls; [WC (cm) - 65]×triglycerides (mmol/L) in boys. The minLAP and adjLAP were described (3% and 50% of WC values, respectively) and the total/high-density lipoprotein cholesterol index (TC/HDL-C) was calculated. NAFLD was observed on ultrasound, and patients were divided into 3 groups by steatosis grade (normal, grade 0; mild, grade 1; moderate-severe, grade 2-3). The area under the curve (AUC) and appropriate index cutoff points were calculated by receiver operator characteristic analysis. Results: LAP was positively correlated with puberty stage (rho=0.409; P<0.001), fasting insulin (rho= 0.507; P<0.001), homeostasis model assessment of insulin resistance (rho=0.470; P<0.001), uric acid (rho=0.522; P<0.001), and TC/HDL-C (rho=0.494; P<0.001) and negatively correlated with HDL-C (rho=-3.833; P<0.001). LAP values could be used to diagnose hepatosteatosis (AUC=0.698; P=0.002). The LAP, adjLAP, and minLAP cutoff values were 42.7 (P=0.002), 40.05 (P=0.003), and 53.47 (P= 0.08), respectively. For LAP, the differences between the normal and mild groups (P=0.035) and the normal and moderate-severe groups were statistically significant (P=0.037), whereas the difference between the mild and moderate-severe groups was not (P>0.005). There was a statistically significant difference between the normal and mild groups for adjLAP (P=0.043) but not between the other groups (P>0.005). There was no significant intergroup difference in minLAP (P>0.005). Conclusion: LAP is a powerful and easy tool to predict NAFLD in childhood. If LAP is ≥42.7, NAFLD should be suspected. This is the first study to assess LAP diagnostic accuracy for childhood obesity.

The objective of this study was to identify the nutritional risk factors by blood analysis, in 1,083 preschool children of age 3 to 6 years. The frequency of anemic children was 7.3% with Hb<11.1 g/dL, 29.9% with ferritin<20 ng/mL, and 16.7% with transferrin Fe saturation(%)<15%. The prevalence of anemia in these children were 12.8% for those with MCV<79 fL, and it was 71% for those with TIBC> $400{\mu}g/dL$. Serum ferritin concentration was 20 ng/mL in the normal children. Thirty two percent of the children had anemia with Hb<12 g/dL, which is below the normal range of Hb. Exactly 15.4% of the children had serum Fe concentration of $60{\mu}g/dL$. The transferrin Fe saturation of the children (16.3%) was >15%. The serum ferritin concentration showed low correlations with Hb, Fe, transferrin Fe saturation, and MCV. The transferrin Fe saturation, higher Hb concentration, MCV, and Hct values were increased significantly. Consequently, iron-deficiency anaemia was thus defined as having Hb concentration <12 g/dL accompanied by ferritin concentration <20 ng/mL or Hct <33%.

The relationship between adolescent children and parents has a profound effect on not only the adolescents development into healthy adults but also the psychological welfare of the parent. A program focused to improve adolescents relationship with parents has not been developed until now. To achieve the educational goals enhancing mutual understanding, it is more effective to educate both the parents and adolescent children. Thus, this study developed and carried out a program in which adolescent children and mothers, being fully in charge of raising children, participated. The study analyzed the program effects after implementing on 6 pairs of adolescent children and mothers. The results are as follows: 1) adolescent children and mothers placed high values on the fact that they can understand each other well, 2) both parties accepted each other by recognizing the inevitability of the generation gap, and 3) the program gave them a chance to admit that they should try to communicate openly. Most of all, adolescent children could find self-confidence while mothers could collect valuable data essential to raise children and build a new mother's role model adapting to social changes.

본 연구는 미혼남녀의 결혼지연 현상을 가치관 접근으로 파악하는 것이다. 2005, 2009 전국 결혼 및 출산 동향조사 중 미혼남녀 5,984명의 자료를 분석하여 결혼, 출산, 성역할 규범 등 가족 가치관의 변화를 살펴보고, 가족 가치관이 결혼의향과 결혼희망연령에 미치는 영향을 살펴보았다. 지난 5년 사이 남성의 결혼과 자녀의 필요성에 대한 동조성은 낮아지고, 전통적 성역할분업과 남성생계부양모델에 대한 동조성은 높아졌다. 여성의 결혼의 필요성과 혼전 동거에 대한 동조성은 높아지고, 자녀의 필요성에 대한 동조성은 낮아진 반면, 성역할태도는 보수적으로 변화하였다. 결혼과 자녀의 필요성에 대한 동조성이 높고 전통적인 성역할태도와 부양모델에 동조하는 사람일수록 결혼의향이 더 높았다. 남녀 모두 결혼 필요성에 대해 동조할수록 결혼희망연령이 빨랐으며, 여성은 혼전동거에 대해 수용적일수록 결혼희망연령이 높았다. 결혼 및 자녀의 필요성과 같은 당위적 규범이 결혼의향에 미치는 영향은 최근으로 올수록 약화된 반면, 자녀의 정서적 가치가 미치는 영향은 최근으로 올수록 강화되었다. 가족 가치관이 미혼남녀의 결혼의향과 결혼계획연령에 영향력을 발휘하고 있으며, 그 영향력이 성별, 가치관 영역, 시기에 따라 서로 다르게 미친다는 것을 알 수 있다.
