In order to assess the physical growth and development, and nutritional status of primary, middle and high school students in the city of Seoul, physiques of 4, 041 persons(Male : 2, 096, Female: 1, 945) were measured from March 1 to July 31 in 1995 and variouis physical and nutritional indices, maximum growth age related to them were calculated. The results are as follows: 1. Physical Growth and Development The growth of body height showed straight linear development among male in the ages 7~16 and among female 7~14, and after that showed slower development. The age of cross over between two sexes was between 11.5 to 12.5 years of age. The maximum growth age was between 11 and 12 years of age(7.28cm) in male and between 11 aqnd 12 years of age(9.77cm) in female. In terms of body weight, it also showed straight linear development among male in the ages 7~16 and among female 7~14, and after that showed slower development. The maximum growth age was between 11 and 12 years of age(7.64kg) in male and between 11 and 12 years of age(8.l9kg) in female. In terms of chest girth, it showed two step development among male in the age of 7~13 and 13~17, and among female in the age of 7~14 and 14~17. The age of cross over between two sexes was 11 and 12 years of age. In terms of sitting height, it showed two step development in the age of 7~14 and 14~17 of both sexes and the age of cross over between two sexes was between 10.5 to 14.5 years of age. The maximum growth age was between 11 and 12 years of age(3.64cm) in male and between 11 and 12 years of age(5.98cm) in female. 2. Maximum Growth Age of Physical Growth and Development In body height, MGA was 10.59 for male and 10.34 for female which showed that MGA for both sexes appeared in similar periods. In body weight, MGA was 10.30 for male and 10.30 for female which showed that MGA for both sexes appeared in similar periods. In chest-girth, MGA was 14.74 for male and 11.60 for female which showed that MGA for female appeared about 3 years earlier than for male. In sitting height, MGA was 11.69 for male and 11.38 for female which showed that MGA for both sexes appeared in similar periods. Maximum growth ages of physiques appeared in order of body height 〉 body weight 〉 sitting height 〉 chest-girth.

The purpose of this study was to compare nutrient intakes, blood lipids and bone mineral density of male (n = 59) and female (n = 172) teachers according to the obesity index by percentage of body fat and age. The energy intakes of obesity group were higher than normal group in male (p < 0.05), but were not significant in female. The protein intake ratio among three energy nutrients for male was higher than female (p < 0.001), and lipid intake ratio of obesity group in female was a little higher than male that was not significant. TC, LDL, TC/HDL, risk of coronary heart disease, blood glucose and blood pressure of obesity group were higher than normal group in female (p < 0.01 ~ p < 0.001), but were little significance in male. Risk of coronary heart disease was affected by gender (p < 0.001), obesity degree (p < 0.01), age (p < 0.001), and interaction of gender and age (p < 0.001). Blood glucose was affected by obesity degree (p < 0.05), but was not affected by age. T-scores of forearm for female (= -1.42) were lower than that of male = -0.95), and T-scores of obesity group in male (= 0.12) were higher than that of normal group (= -0.33) but were not significant in female. The T-scores of forearm for female were affected by age (p < 0.05) and gender (p < 0.01), but calcaneus was not affected by gender. These results suggest lipid intake ratio should be balanced for obesity group in female. Nutritional education for treatment obesity to prevent hyperlipidemia and arteriosclerosis is necessary for obesity group and older age groups. T-scores of forearm were lower than calcaneus, so arm exercise would be especially required to prevent osteoporosis for older age women groups.

To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.

The purpose of the present study was to examine married female immigrants' life style and marriage satisfaction on the perception of preparing their old age. We also investigated how socio-demographic factors influence their Preparation for old age. For the study, -data were collected from 350 questionnaires obtained from female immigrants living in Chungcheongnam-do. Cronbach's ${\alpha}$ tests were conducted for reliability, and regressional analysis was conducted to test our hypotheses. The results of this study shows that there is evidence of relations among the sub-variables. However, we found attitudes to safety and material pursuit are not related to married female immigrants' preparations for their old age. On the other hand, the results indicate that their life style and marriage satisfaction influences their perception of preparing their old age in a positive way. Finally, sociodemographic factors such as gender, age, education, marriage status, occupation and income are shown to affect the women's perception of preparing their old age positively.

Using the 1998 Survey of Consumer Finances(SCF), this study examined the factors associated with the probability of saving by female-headed households in the U.S, and investigated how these factors differ by life cycle stages. Age of children, age of female householders and their retirement status were used to categorize three life cycle stages: first stage - have at least one child under age 18; second stage - under the age of 62 and have no children under age 18; third stage - over the age of 62 and retired. Logistic regression analysis results indicated that those with higher education and income and who were White were more likely to save. An interactive model showed that life cycle stages were significantly related to saving decisions. Female-headed households in the first stage or the third stage were less likely than those in the second stage (reference group) to save. For female-headed households in the first stage and the third stage, the amount of income had significantly positive effects on the decision to save. Also, in the group of households in the first stage, the receipt of welfare assistance increased the probability of saving.

Purpose: The study was done to investigate Food and Nutrient Intakes of female college students and define differences between teen-age groups and women in their twenties. Method: The subjects of this study were 821 female college students. They were eighteen to twenty nine years old. Nutrient intakes were measured by the Moon, S. J. Scale (1980). Data was collected from June 13 to June, 27. Data was analyzed with the SPSS program by Chi-test, t-test and Pearson's correlation coefficients. Result: Female college students' mean intake of calories, protein, fat, and carbohydrates were $1560.7{\pm}367.71kcal,\;62.0{\pm}19.03g,\;33.1{\pm}9.85g,\;and\;253.7{\pm}57.52g$ respectively. Their mean intake of calcium, phosphorus and iron were $592.9{\pm}221.82mg,\;918.2{\pm}284.24mg\;and\;13.7{\pm}4.50mg$ respectively. Intake of calories, calcium, iron and vitamine B1 were below their Percent of Recommended Intake. Nutrient intakes showed a significant difference between age groups. Teen-age female college students had more nutrient intakes than the women in their twenties. In addition, there was a difference in food consumption behaviors between the teen-age group and the twenty-something group. Conclusion: The nutrient intake of female college students changed by age. Many teen-age female college students ate breakfast well, thus their intake of calories, protein, fat, carbohydrates, minerals such as calcium, phosporus and vitamins was significantly higher than the over twenty years old students. Teen-age female college students like fruits and sugars but over twenty years college students preferred coffee. This study can be useful in directing a dietary consumption status of women to improve nutritional health.

The purpose of this study was to describe the gait pattern and parameters of the healthy elderly over 65years of age by the GATERite system. The subjects were sorted into two groups, depending on their sex: male and female. And female subjects were sorted into three groups, depending on their age. From time parameters and space parameters of gait cycle, between groups, the following results were made. The time parameters such as cadence, velocity, step time, single support and double support were the less the male than the female. And the higher age, the lower value except 80 age group, while no statistically significant. The space parameters(step length and stride length) were the longer the male than the female, and the higher age, the lower value while no statistically signigicant. The functional ambulation profile was high correlation with time and space parameters statistically significant.

Sixteen crosses from two strains of White Cornish and White Plymouth Rock were reared seperately on floors and abdominal fat was measured every two weeks interval from two weeks to twelve weeks of age. The abdominal fat weights surgically removed were slightly heavier in female than male. Estimates of general combining ability variances of body weight showed significant at all weeks of age in both sexes but those of abdominal fat weight were significant at 2, 8, 10 and 12 weeks of age in female and 2, 6 and 12 weeks of age in male. In percentage of abdominal fat to body weight, the significant differences were observed at 10 and 12 weeks of age only in female. The specific combining ability variances were significant at 4, 6, 10 and 12 weeks of age in female and 4, 8 and 12 weeks of age in male in body weight. In abdominal fat weight, there were significant differences at 4, 8, 10 and 12 weeks of age in female but no significant differences in male. The specific combining ability variances of percentage of abdominal fat to body weight showed significant differences at 4 and 8 weeks of age in female but no significant difference in male.

The author measured the vertical dimension and the distances from Trichion to Nasion of 825 Korean adults (414 of male, 411 of female) above 21 years of age by Willis gauge. The following results were obtained. 1) The distances from subnasale to the bottom of chin were 71.4mm in male and 68.7mm in female, and those from Trichion to Nasion were 70.4mm in male and 68.0mm in female. The former were longer than the latter, and the distances in male were longer than those in female. 2) The differences between the distances from Subnasale to the bottom of chin were 1.0mm in male and 0.7mm in female. The frequencies of percentages, in which differences between the distances mentioned above were 0±1mm, were 43.0% in male, 42.6% in female, and 42.8% in total. 3) With the matter of age and sex differences, the distances from Subnasale to the bottom of chin and those from Trichion to Nasion were increasing to 31-40 age group by age, but those had a tendency of decreasing in the late age in both sexes.

The food consumption of 148 healthy infants from 4 to 6 months of age have been measured. Three groups were assigned to change of feeding pattern. Formula group(FF, n=102) were fed formula from birth till 6 months of age. Convert 1 group (C1F, n=14) and Convert 2 group (C2F, n=32) were fed breast milk and mixed milk at 2months of age afterthat switched to formula milk, respectively. All infants received solids (solid foods) from 4 months of age. No significant difference was found in the intake of nutrients among three feeding groups excluding carbohydrate intake of C1F-female at 4 months of age. No significant difference was found in the intake of nutrients among three feeding groups excluding carbohydrate intake of C1F-female at 4 months of age. The FF-female(70.9g/d) and C2F-female(66.9g/d) had significantly higher carbohydrate intake when compared to the C1F-female (54.3g/d). The average total energy intake at 4, 6 months were 648.3 and 709.7kcal/d among all infants. At 4 and 6 months of age, mean intake of nutrients was as follows. Calcium intake was 526.7mg/d and 760.0mg/d at 4 and 6 months of age respectively. Iron intake was 8.3mg/d and 10/5mg/d at 4 and 6 months of age respectively. Calories from solids provided 22.5% of total energy intake at 4 months of age, and nearly 32% at 6 months of age. The average energy and protein intakes of all infants were less than the RDA for calcium and iron at 4, 6 months of age.
