Purpose: Somatic growth is an important indicator of health in children. Adequate organ growth is essential in growth and directly related to body growth. We consider renal length as a surrogate of organ growth in growing children. Measurement of weight, height, and many anthropometric indices, such as body surface area (BSA), body mass index (BMI), and Rohrer and Kaup indices, are used to evaluate growth status. The aim of this study was to evaluate the association between renal length and somatic parameters and analyze the affecting factors for renal size during growth. Methods: The data for renal length in 66 children (age, $12.9{\pm}15.6$ months; male/female, 34/32) were obtained. Each kidney was measured with ultrasonography and dimercaptosuccinic acid scan. The data on age, sex, height, and weight were obtained from the medical records. BSA, BMI, and Rohrer and Kaup indices were calculated from measured height and weight. BSA was calculated by 2 methods, and is expressed as BSA I and BSA II. Results: There were significant correlations between renal size and age, weight, height, BSA I, BSA II, and Rohrer index. In the regression analysis, the most significant contributing factor to renal growth was height ($R^2$=0.636, $P$ <0.001). Conclusion: Height seems to be the most important factor associated with organ growth in growing children. Further studies to evaluate adequate organ growth should be carried out.

A series of pot experiments were conducted to quantitatively estimate inhibitory effects of reclaimed soil on the growth of Lentil (Lens culinaris) with two soils remediated by land farming (DDC) and low temperature thermal desorption(YJ), respectively. After cultivation in a growth chamber for 8 days, plants were harvested for the analysis of 8 indices including chlorophyll-a and carotenoid in leaves, shoot fresh weight, root dry weight, root length, number of later roots, specific root length (SRL) as well as germination rate in comparison to control experiment conducted on nursery soil. Root length was estimated by SmartRoot program from the digital images of the roots. The results showed germination rate on YJ and DDC soil decreased 29 and 71%, respectively. In comparison to the control, the averaged value of the 8 indices for YJ and DDC soil showed overall growth inhibition was 48 and 68%, respectively. When the same experiment was conducted with 25% (W/W) vermiculate amended soil, plant growth on each soil was comparable to that of the control. The results implies reclaimed soils requires additional processes and/or amendments to reuse for plant growth.

This study analyzes the body characteristics of Korean obese women using 2004 Size Korea data. For selecting the obesity sample, 7 obesity judgment indices were chosen from previous clothing-related studies. A total of 636 females defined as "obese" by 5 out of 7 indices were selected as subjects for this study. 54 body measurements and obesity judgment indices were used. First, the subjects had a BMI 27.11, R$\ddot{o}$hrer index 1.76, Vervaeck index 104.77, Relative weight 133.00, and WHR 0.90. In the case of the distribution by age groups, the twenties were 6.4% of the entire subjects, the thirties were 18.2%, the forties were 16.4%, the fifties were 37.4%, and the sixties were 21.5%. The result of the ANOVAs (divided into 5 age groups) showed significant differences in 41 measurement items except for bust circumference, waist length front, and all of obesity judgment indices. Second, according to the ANOVAs among stature groups divided by 5cm pitches there are significant differences in all measurements except for bust circumference. The results of the ANOVAs among bust circumference groups divided by 5cm pitches show that significant differences were observed in all measurements except four measurement items (including body rise). According to the ANOVAs among the waist circumference groups divided by 5cm pitches, there are no significant differences in all height measurements and shoulder length, waist to hip length, and crotch length. It is confirmed that stature and bust circumference have a deep relationship with measurements other than waist circumference. Third, as the factor analysis were conducted using 39 measurement items to extract the body characteristics of obese women Factor 1 is "circumference measurements & obesity judgment indices," Factor 2 is "heights & arm-related lengths," and Factor 3 is "size and ratio of waist circumference & hip circumference." Factor 4 was "lengths in upper body," Factor 5 was "back width in upper body," Factor 6 was "side neck point to bust & bust circumference," Factor 7 was "length in lower body & arm circumferences," and Factor 8 was "neck base circumference & front widths in upper body." These 8 factors explained 76.54% of the total variance.

The purpose of this study is to assess the maternal iron status during pregnancy and to evaluate the relationships bet-ween the iron indices of maternal, umbilical cord serum, placenta and pregnancy outcomes. Venous bloods samples were drawn from 54 pregnant women just before delivery and cord bloods of their newborn babies were collected immediately after birth. And also, placental tissues were extracted. We investigated the difference of the iron status indices of maternal, umbilical cord serum and placental tissue between two gestational age group (PT group, NT group : preform delivery and normal term delivery at 34.9wk and 39.0wk of mean gestational length, respectively) and also assessed correlations of iron status indices of maternal, umbilical cord serum and placenta tissue. And lastly, we related between birth weight and iron status indices of maternal, umbilical cord serum and placental tissue. The concentrations of maternal serum ferritin and of placental iron were significantly higher in NT group (32.1 $\pm$ 21.1 ng/ml, 68.5 $\pm$ 16.7 $\mu$g/g), than those of NT group (20.8 $\pm$ 11.6 ng/ml, 53.2 $\pm$ 17.4 $\mu$/g) respectively (p<0.001). However the serum ferritin of umbilical cord were significantly higher in NT group (PT : 109.4 $\pm$ 65.7 ng/ml, NT : 147.0 $\pm$ 56.8 ng/ml) than those of PT group (p<0.05). Our results showed that a negative association between birth weight (r=-0.361) and maternal serum ferritin and that a positive association between birth weight and umbilical cord serum ferritin (r=0.261). Despite not a significant difference, there was tendency that highest concentration of maternal serum ferritin was associated with the lowest birth weight. These findings indicate that birth weight of newborn is dependent of multiple factors such as maternal iron status during pre-pregnancy, body size, general nutritional status. Although for women who enter pregnancy with low iron stores, enough intakes of iron during pregnancy could produce undesirable pregnancy outcome. Therefore we suggest for successful pregnancy outcome and delivery differential iron supplementation program will be carried out individual pregnant women on the basis of pre-pregnancy nutritional status.

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 purpose of the study was to investigate the body cathexis, ideal body shape, clothing satisfaction and their interrelationships. The subjects were 445 middle- and high- school girls. The findings were as follows : the subjects were more satisfied with their face appearance than body parts. They were very unsatisfied with thigh. leg and weight. Generally they were more satisfied with upper body than lower body, and more satisfied with length measurements than girth measurements. They accepted 169.19cm as ideal height and 49.18kg as ideal weight. The middle-school girls wanted to be taller than high-school girls by 3cm. But the ideal weight of both were almost same. The Rohrer indices indicated that the subjects were normal to slender type. But the Rohrer indices calculated using ideal height and ideal weight showed that the subjects thought extremely slender type as ideal body shape. The attitude of body was evaluated by two factors. the awareness of body shape and the physical attractiveness. The awareness of body shape was deeply influenced by girth measurements and lower body parts. And physical attractiveness was severely affected by face appearance. Weight was more important than height in regard to body cathexis. The ideal body shape was independent of individual situation but was formed by social value. The satisfaction of clothing in terms of design related aspects was influenced by body cathexis. Also the more satisfied with their body. the more they felt comfortable for their clothing. The body cathexis was interrelated with the satisfaction of clothing in some aspects.

This study explored the effects of dietary calcium level and Hijikia fusiforme supplementation on bone indices and serum lipid levels using 36 female Sprague-Dawley rats as a model. Rats received low Ca diet for 3 weeks after ovariectomy. The rats were then divided into six dietary groups and fed low (0.1% Ca), normal (0.5% Ca) and high (1.5% Ca) Ca diets (CaL, CaN, CaH) and low, normal, high Ca diets with Hijikia fusiforme supplementation (CaLH, CaNH, CaHH) for 3 weeks. After each experimental periods, 24 hour urine and/or blood samples, left and right femurs were collected for analysis. Serum Ca concentration showed no significant difference by dietary Ca levels and Hijikia fusiforme supplementation. Alkaline phosphatase activity was significantly higher in normal and high Ca group compared to low Ca group. Serum total cholesterol, triglyceride and total lipid were not significantly different among groups. HDL-cholesterol showed no significant difference by Hijikia fusiforme supplementation. However, the normal and high Ca groups showed significantly higher HDL-cholesterol compared to the low Ca group. Urinary hydroxyproline and hydroxyproline/creatinine ratio were not significantly different among groups. The wet weight of the femur was significantly higher in low Ca group compared to normal or high Ca group. The dry weight, wet weight/body weight, length and breaking force of the femur were not significantly different among groups. Ash contents/wet weight of the femur was significantly increased as dietary Ca levels up and significantly higher in Hijikia fusiforme supplementation groups. The Ca content of the femur were significantly higher in the normal and high Ca groups than the low Ca group. However, there was no significant difference in Ca content by Hijikia fusiforme supplementation.

The purpose of this study was to assess several indices of diet quality based on nutrient, food and food group intake of Korean adolescents based on several indices on diet quality according to residence area and body size. Using the data from the 1998 National Health and Nutrition Survey, twenty-four-hour-dietary recalls of a total of 1,110 Korean adolescents aged 13 - 19 years (male 543, female 567) were analyzed for nutrient adequacy ratio (NAR) , index of nutritional quality (INQ) , the number of foods (Dietary Variety Score, DVS) and food group consumed (Dietary Diversity Score, DDS) . In doing that, it was attempted to apply only the minimum amount of solid foods of Kant's without inclusion of liquid foods because of the very limited variety in Korean foods. Based on weight length index, 13.1% of the subjects were categorized as obese, 14.2%, overweight, 44.4%, normal and 28.3%, underweight. Only vitamin B2 intake was higher in the obese group than in the underweight group. There was no meaningful difference in energy, protein and fat intakes according to the grade of the body size. In terms of residence area, intake of fat, niacin, vitamin $B_6$ and folic acid were lower in the rural areas than in the metropolitan city. Only vitamin E intake was higher in the rural areas. Mean value of NARs (MAR) and INQs (mINQ) was also higher in the metropolitan city than in the rural areas, but there was no significant difference of these two values according to body size of the subjects. Mean DVS was 21.02 for total subjects, and has no difference between male and female and between metropolitan city and other medium-small city. But, the rural areas showed the lowest DVS of 19.05. Mean DDS in which five is a maximum score was 3.3 with no significant difference by sex and by residence area in male subjects. However, in female subjects, DDS in the rural areas was the lowest. According to body size of the subjects, there was no meaningful difference in both scores of DVS and DDS. In conclusion, most indices of nutrient intake and food and food group intake were not significantly different by body size of the subjects, while most indices were significantly different by residence areas: higher in the metropolitan city than in the rural area.

Condition index(Cl)는 일반적으로 이매패류의 영양상태와 건강 등의 생리적인 상태를 알기 위한 중요한 지수이다. 이 연구는 제주도 추자 연안에 서식하는 홍합(M.coruscus)의 Cl를 다음과 같은 세 가지 방법으로 산출한 뒤, 이를 비교하였다: (1) Cl-vol=[tissue dry weight(g) 1000]shell cavity volume(ml). (2) Cl-wt=[tissue dry weight(g) 1000]internal shell cavith capacity(g). (3) Cl-size= tissue wet weight(g)/[shell length (mm)]$^{3}$. Cl-vol 산정을 위한 패각내 부피는 아르키메데스의 원리를 이용하였으며, 전체 부피와 육질을 제거한 패각의 부피 차를 이용하여 산출하였다. 월 별 세 가지 Ci들의 변화는 Pearson의 상관계수, 분산분석(ANOVA)과 Duncan의 다중검정법을 사용하여 세 지수의 유의성과 처리평균간의 근사 정도를 검정하였다. 실험에 이용된 홍합의 크기는 각장 50-180 mm 이었다. 세 지수의 범위는 67.48-140.61(CL-vol), 74.67-118.02(Cl-wt), 1.40$^{-5}$-1.60$^{-5}$(Cl-size)였다. Cl-vol은 Cl-wt, Cl-size와는 다르게 계절에 따른 유의차를 보였으며(p<0.05) 8월에 가장 높은 수치를 보였다. 그러므로 패각내 부피를 이용한 Cl는 홍합의 상태를 제시하는데 있어 가장 효율적인 것으로 사료된다.
