The purpose of this study was to determine the effects of nutrient intake, screen time (television viewing and computer and/or video games) and physical activity on obesity in preschool children. Recruitment began in January 2008 by distributing letters to mothers who had children aged 6 years enrolled in daycare. Dietary intakes were obtained from the children's mothers, using the 24-hour recall method. The average height and weight of the children were 114.2 cm and 20.3 kg, respectively. Mean age, body weight, height and Kaup index were not significantly different between groups consisting of boys or girls. Assessment by the Kaup index showed that 14.0% of children were underweight, 69.0% were normal weight, 13.0% were overweight, and 4% were obese. The daily intakes of calcium, potassium, fiber, and folic acid in the group of boys were 77.7%, 58.5%, 80.4% and 88.9% respectively. as compared with the DRIs. The daily intakes of calcium, potassium, fiber, and folic acid in the group of girls were 77.7%, 58.5%, 80.4% and 88.9%, respectively. as compared with the DRIs. Intakes of protein, phosphorus, iron, zinc, vitamin A, thiamin, riboflavin, niacin, vitamin C, and vitamin E were higher than the DRIs. There were no difference among 3 groups (underweight, normal, overweight) in energy or nutrient intake. Preschool children with screen time (TV viewing and computer and/or video games use time) of >2 hours per day had significantly higher Kaup index values, and intakes of energy, carbohydrate, folic acid and zinc. In conclusion, preschool children with reported screen time (TV viewing and computer and/or video games use time) of >2 hours per day were fatter. Therefore, we need further investigate the relation between diet and screen time in preschool children to improve future nutrition education programs. Further studies are required to explore the effects of food intake and screen time (TV viewing and computer and/or video games use time) over a longer period of time.

The purpose of this study is to analyze the factors associated with health and diet by nutritional status. The subjects were the children aged 2 to 6. Physicians and nurses measured children's anthropometries and examined their blood and urine. Interviewers questioned children's food habits to their mothers. 24 hour recall was done for children with their mother. The nutritional status was classified to 'underweight', 'normal weight' and 'overweight' by weight for height(median±1 S.D.) of the reference population. The number of subjects in each group(under, normal, over) was 25, 130 and 49. Factors including anthropometry and hemoglobin concentration were not significantly dif ferent by the nutritional status. The birth weight of children was correlated positively to mothers' BMI. Z scores of weight for height were related to the birth weight positively by the analysis of variance. The children of the underweight group used nutritional supplements more frequently than those of normal and overweight group. The nutrient intakes of normal weight group were higher than those of low and overweight group. Particularly, the intakes of energy, carbohydrate and calcium were significantly high among the groups. In terms of number of foods, food groups and dishes consumed per day, the children of the normal weight group ate more diversely than other groups but the differences were not significant. In conclusion, the children of normal weight group had similar characteristics with other groups but had more desirable dietary intakes than other groups in this study. Because the diet of children may be different by the nutritional status, nutrition education for children should be conducted according to the characteristics of each group's diet.

The purpose of this study was to estimate the nutrient intake, dietary habits, and body indices among preschool children. The study subjects were 166 kindergarten children, aged 4 to 6 years. A measurement of the weight, height, chest circumference, and head circumference of the children was conducted. The general home environment and factors related to the eating habits of children were collected using a questionnaire that included information about physical activity, outdoor playing time, television watching, family income, and parents education and occupations. Underweight, overweight were defined based on a value of less than 110 and more than 140 on the Rohrer Index, or less than 90 and more than 120 on the weight-length index (WLI). The average Rohrer and WLI for the preschool children were 14.3 $\pm$ 23.2% and 104 $\pm$ 13.5%. Using the WLI, 12.7% of the preschool children were underweight 62.6% were normal, and 24.7% were overweight or obese. On the Rohrer Index, 32.0% of the preschool children were underweight, 34.7% were normal, and 34.1% were overweight or obese. With regard to frequency of regularity of eating breakfast, 2.5% of preschool children skipped breakfast every morning. The risk of being overweight increased in preschool children who had faster eating times. The Rohrer and WLI were negatively related to faster eating times. The average daily energy intake was 1272 Kcal, which corresponded to 79.5% of the Korean RDA. In particular, the average intakes of calcium, iron, and vitamin B$_2$ were much lower than the Korean RDAs for each of those nutrients. Children whose mothers had occupations were at greater risk of decreased nutrient intake than those whose mothers were at home. The data presented in this study confirm that, in preschool children, undernutrition remains the nutritional problem of great concern in Korea, even though Koreans are starting to have worrisome rates of overweight. Therefore, during the early years of life, focus should remain on sustaining Proper growth and development.

The study was designed to observe the correlation between the eating habits and growth development in 1,574 children (3-6 years old) in Kyunggi-do and Seoul, Korea. The eating habits and nutrient intake were determined by mini dietary assessment and food frequency questionnaire (FFQ). 35.6% children had been practicing an unbalanced diets. Children with unbalanced diet consumed less amount of protein source foods (meat, fish, egg, soy products), vegetables and fruits and had irregular meal time, but more of them preferred sweet foods (ice creme, cookies) and carbonated drinks as snack compared with children in balanced diet. 24-35% children consumed energy, iron (Fe), calcium (Ca), Niacin, Zinc (Zn) less than 75% RDA. Energy intake of children with unbalanced diet was not significantly different from those with balanced diet, but they consumed less amount of niacin, Fe, Ca and Zn than those with balanced diet. By using the relative percentage of standard weight-length-index (WLI), 65.7% children was normal weight, 12.9% was underweight, 13.4% was overweight and 7.9% was obese. However, 11.9% of underweight and normal weight children was so called thin obese since their body fat content was greater than 20%. There were 16.8% underweight in children with unbalanced diet and 12.6% underweight in those with balanced diet. Compared to normal weight, the underweight children significantly consumed less amount of milk and its product, high protein foods, fried foods and fruits, but obese children consumed more high protein source foods (meat, fish, egg, etc) and sweet foods. In conclusion, the eating habits of unbalanced meal was prevalent problem in preschool children which resulting in their health risks. Therefore, it would be needed that new approach for nutrition education to improve eating habits in preschoolers.

본 연구는 관리적 목적에서 대학의 학과 홈페이지 평가를 위한 TOPSIS 기반의 응용을 제시한다. 학령인구 감소시대를 맞아 대학의 학과 홈페이지는 입시 전략의 관점에서는 중요한 홍보 수단의 의미를 갖는다. 하지만 대부분 리뉴얼과 같은 전면적 개편 전에는 관리가 잘되지 않는다. 비록 입시전략 차원에서 홈페이지 관리는 중요한 일이지만 단순한 관리 목적의 평가에 많은 노력이나 비용을 투자하기는 어렵기 때문이다. 그래서 본 논문은 현실성을 고려하여 관리 목적에서 대학의 학과 홈페이지 평가에 부분적으로 수정된 TOPSIS를 적용하여 그 유용성을 보이고자 한다. TOPSIS는 각 기준에 대한 이상적인 목푯값으로 부터 편차 거리를 기반으로 하여 우선순위를 결정해 주는 개념적 이유로 목표 관리를 위한 평가도구로 사용하기에 합당하다고 본다. 그리고 사용되는 평가 기준들의 방향성이 같은 단조증가 함수 같은 경우 본 연구에서 제시된 바와 같이 부분적으로 수정된 절차를 통하여 계산량을 줄여도 동일한 결과를 얻을 수 있다.

We conducted this study to determine the factors associated with childhood obesity. The subjects were 170 preschool children in Busan. Data were collected by using questionnaires which asked for information about socioeconomic status, parental perception of their child's weight status and dietary/physical activity behavior. BMI was calculated for each child and their classification was determined, according to their age and sex, as follows: "overweight" at or above the 85th percentile, "normal" for the 15th-85th percentile, and with a BMI below the 15th percentile the children were deemed as underweight. Classification according to BMI percentile showed that 23.5% ($18.25{\pm}1.33\;kg/m^2$) of the children were overweight, 62.9% ($15.51{\pm}0.76\;kg/m^2$) normal, and 13.5% ($13.23{\pm}2.86\;kg/m^2$) were underweight. Socioeconomic status, as represented by the parents' level of education, the occupation of the father and the household income, did not affect the results. However, mothers working outside the household was a factor that was more likely to affect the weight status (p<0.05). Among mothers whose children were overweight, 30% underestimated their children's weight status (believing them to be of normal weight when they were overweight), and 25% failed to recognize the necessity of weight control for their overweight children. While sedentary activity and total daily activity levels were not related to BMI, the level of physically active leisure activity was inversely correlated with BMI (p<0.05). Although there were no differences in total energy intake, dietary behavior was significantly related to weight status. Overweight children had poor eating tendancies: they eat faster (in less than 15 minutes), overeat, and eat late at night. Based on our findings where hereby recommended the following interventions to help limit weight problems in Korean pre-schoolers: early promotion of active leisure behavior and healthy eating habits, along with attempting to correct parental misperception of healthy weight status for children.
