The purpose of this study was to investigate the effects of parent's nutritional education for body weight control of obese children. The weight control program include nutritional education, exercise and behavioral therapy during 20 weeks. Twenty- three children completed this program, the children were divided into two groups by control group and parent's nutritional education group. Parents volunteered to participate in a 4 week nutritional education program for parents and contact the therapist at least once per week to help their obese children. The results from this study were as follows. There were not significant differences in anthropometric values after weight control program between two groups. Triglyceride(TG) level in serum was decreased after weight control program in group of parent's nutritional education, but there was not significant difference. Parent's nutritional education did not add improvements in weight and fitness, but the children of parent's nutritional education group showed increased general self-worth upon completing the program(p<0.05) whereas the other children of control group did not. Also there were desirable changes of exercise and life habits in group of parent's nutritional education group.

The objectives of this study were to examine the growth pattern and hair trace element contents of healthy infants who were fed breast milk(BF infant) and formula (FF infant) during the first 6 months and its relationship to intake of trace elements. Bimonthyl anthropometric measurements were obtained on 32 infants through 6 months of age. Mean calculated energy, iron, zinc and copper intake from breast milk at 2 months of age were 432.4kcal/d, 0.19mg/d, 1.18mg/d and 0.22mg/d. The values obtained from formular were543.7kcal/d, 6.68mg/d , 2.82mg/d and 0.33mg/d , respectively. In spite of the significantly lower intake of energy and trace elements in BF infants than in FF infants, BF infants showed growth above the average Kroean infant standard growth rate and showed no significant growth rate difference or hair trace element content. Hair iron content in the BF infants at 6 mo. of age was positively related to birth weight and iron intake at 2 mo. of age. In contrast, hair zinc and copper content in the FF infants at 6 mo. of age as negatively related to height increment and weight increment during 6 months, respectively. These results support the suggesting that BF infant's higher iron, zinc and copper intake is attributed to the superior bioabailability of these trace elements from breast milk.

Malnutrition is a common problem in patients undergoing maintenance hemodialysis(HD) and compromised food intake is an important cause. Malnutrition is one of the important factors influencing mortality in chronic HD patients. We investigated the nutritional parameters of 50 Korean HD patients(mean age: 46.9 $\pm$ 10.3y, men : 23, women : 27) by measuring anthropometric and biochemical blood indices and assessing food intake using 24-h recall method. Also we administered two questionnaires, one for assessing nutritional knowledge about renal disease and dietary therapy, the other for measuring dietary habits related to dietary therapy. According to the distribution of BMI, 21.3% of HD patients were underweight. The hematological values of HD patients, such as plasma hemoglobin, hematocrit, and total lymphocyte count were below the normal range. The serum cholesterol levels were 133.2 $\pm$ 30.5mg/dl. HD patients took energy and protein only 77.5% and 83.1%, respectively, of their RDA. There were significantly positive correlations between nutritional knowledge and intake of nutrients, such as energy, fat, cholesterol, iron, potassium, vitamin B$_1$, vitamin B$_2$, and niacin. Also, there was a significantly positive correlation between nutritional knowledge and dietary habits(r = 0.317, p < 0.05). In conclusion, Korean HD patients showed mild malnutrition and suboptimal nutrition intake. It can be postulated that the dietary intake can be increased by nutrition education improving nutritional knowledge and correcting the dietary habits of HD patients.

A untrition survey of early childhood was undertaken among 102 rural young children, aged 3 to 6, attending three day care centers of Hongcheon-gun, Kangwon province, in July of 1987, to investigate dietary and nutritional status. The results were obtained as follows: Mean values of height and arm circumference ranged from 96 to 97% of the KSRI's standards. However, mean value of weight met 91% of that standard. Mean value of hematocrit was 37.3±3.5%. According to the criterion established by the WHO, 3% of the subjects were proven to be anemic. Mean value of urinary urea nitrogen/creatinine ratio was 13.8±7.6; the higher the age lower the ratio was shown. Intake of energy and nutrients ranged from 63 to 88% of the RDAs. Carbohydrate provided 68% of total energy intake; protein accounted for 14%; fat provided 18%. Energy intake was divided among breakfast, lunch supper and snacks in a percentage ratio of 21:35:26:18. The survey clarified that the day care feeding largely supplemented the inadequate dietary intakes of these young children at home. Family factors, anthropometric measurements, biochemical results were positively correlated with nutrient intakes. Authors with this study can be contributed, as a reference, to develop the community nutrition programs as well as improving the quality of day care feeding.

This study established a lower garment sizing system for abdominal obesity adult women aged 30-59 based on 277 females selected from the 7th Size Korean Anthropometric survey. The criteria for subjects in this study were over 25 kg/㎡ of the BMI, over 85 cm of waist, and over 0.8 waist hip ratio. The results are as follows. The lower body analysis of abdominal obesity adult women showed that average circumference items were larger than the ordinary size, and the average length items were smaller. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for abdominal obesity adult women. The interval between the designation was ±1.5 cm with a waist circumference of 100 cm and ±2.5 cm with an average hip circumference of 100 cm. We established 13 designation sections in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 71.5%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes that helped enable rational production.

A study on the standard cardiothoracic ratio calculated from the photofluorography film of chest in a total of 8,030 insured persons(3,449 men and 4,581 women) was undertaken. The results were as follows: 1) The linear regression equations were formed from the 99% confidence ilmits of actually measured average cardiothoracic ratio by weight index. The cardiothoracic ratios by weight index estimated by above mentioned equations, namely theoretic values of cardiothoracic ratio, should be regarded as the standard cardiothoracic ratios. 2) It seems that the standard cardiothoracic ratio${\pm}10%$ deviation should be regarded as the normal limits of cardiothoracic ratio. 3) The tables of standard cardiothoracic ratio by weight index and the normal limits of cardiothoracic ratio by weight index were presented. 4) The average weight index and cardiothoracic ratio in all males and females were 0.993 and 43.3%, and 0.997 and 46.3% respectively. 5) In order to evaluate the cardiothoracic ratio more accurately, the establishment of the standard cardiothoracic ratio by build is considered to be reasonable.

This study was undertaken to identify factors affecting school food waste generation using a questionnaire. The subjects were 254 high school students (male; 156, female; 98) in Sacheon, Gyeongnam divided into three groups of low (${\leq}1/week$), moderate (2~3/week), and high (${\geq}4/week$) according to the frequencies of food waste. The questionnaires consisted of general characteristics, anthropometric values, dietary habits, health-related behaviors, self-perceptions of food waste, snacking patterns, and nutrition knowledge. The main reasons behind food waste were 'too much food' in the low (20.9%) and moderate (32.2%) groups, and 'no appetite' in the high group (p<0.01). The main types of food waste were rice (44.2%) > fish (18.6%) > vegetables (14.0%) in the low group, rice (54.2%) > Kimchi/vegetables (15.3%) in the moderate group, rice (56.0%) > vegetables (20.0%) > Kimchi (16.0%) in the high group (p<0.01). School food waste was significantly affected by age, gender, monthly allowance, school grade, weight, BMI, regularity of meals, time of meals, type of breakfast, starting age of smoking, and cost for snacking.

A group of digital human models with various sizes which properly represents a population under consideration is needed in the design process of an ergonomic product in virtual environment. The present study proposes a two-step method which produces a representative group of human models in terms of stature and weight. The proposed method first generates a designated number of pairs of stature and weight within an accommodation range from the bivariate normal distribution of stature and weight of the target population. Then, from each pair of stature and weight, the method determines the sizes of body segments by using 'hierarchical' regression models and corresponding prediction distributions of individual values. The suggested method was applied to the 1988 US Army anthropometric survey data and implemented to a web-based system which generates a representative group of human models for the following parameters: nationality, gender, accommodation percentage, and number of human models.

In this paper, the ride comfort from a computer simulation was compared to the experimental result. For measuring ride comfort of a passenger car, acceleration data was obtained from the floor and seat during highway running with different speeds. The measured acceleration components were multiplied by the proper weighting functions, and then summed together to calculate overall ride values. Testing several passenger cars, the ride comforts were compared. In order to investigate the effect of vibration signals on the steering wheel, an apparatus to measure the vibrations and weighting functions on the steering wheel were designed. The effect of the steering accelerations on the ride comfort were investigated and added for the overall ride comfort. For the computer simulations, Korean dummy models were developed based on the Hybrid III dummy models. For the Korean dummy scaling, the national anthropometric survey of Korean people was used. In order to compare and check the validity of the developed Korean dummy models, dynamic responses were compared to those of Hybrid III dummy models. The computer simulation using the MADYMO software was also compared to the experimental results.

This study established a lower garment sizing system for elderly men over 65 years of age based on 535 males selected from the 5th Korean Anthropometric survey. The results are as follows. Most elderly men body measurements were smaller for adult males (except for the waist area); however, abdominal obesity has changed to body type. The standard deviation was applied around the average values of waist circumference and hip circumference for the suggestion of a lower garment sizing system for elderly men. The interval between the designation was ${\pm}2.5cm$ with an average waist circumference of 86 cm and ${\pm}2cm$ with an average hip circumference of 92 cm. A total of 13 designation sections were established in consideration of the cover ratio and cover efficiency. The cover ratio in the 13 nominal sections was 77.2%. The segmental distribution rate presented in the results will also be useful for production planning in specific sizes and enable rational production.
