The purpose of this study was to examine the phenomenon of social participation among female baby boomers. The key research questions were asked in what kind of activities do female baby boomers engage as social participation? The in-depth interview was used with 11 female baby boomers who were born between 1955 to 1963. The interview text were analyzed by the qualitative study method. The findings are as follows. First, the most common type of social participation was having hobbies and leisure activities, and the other were participating in religious activities, learning activities, volunteer activities and on-line club activities. Second, social participation gave them meanings such as joy, satisfaction, and experiences of seeing the new world as well as opportunities to make up low sense of self-esteem formed in their young age. Third, they were considering it was time to change their social participation. The cases who were actively engaging in social participation considered old age as 'the process of reducing social participation'. Some other cases considered to 'share hobbies with spouse', and to 'achieve new goals and dreams'. The results showed that female baby boomers started their social participation in their middle ages when they became free from their children's education. The level of the involvement in social participation was reduced in their old age. Surprisingly, some interviewees planned to accomplish their dreams and goals that they haven't achieved yet. These differences among the cases could be attributed to the individual characteristics such as personality, birth order, economic and educational background, and to the social relationship.

A statistical analysis on the ratio of weight-for-height in insurance medicine was carried out in a total of 12,690 insured persons who were medically examined at the Honam medical department, Dong Bang life insurance company, ltd. from June, 1979 to February, 1984. The results were as follows: 1. The mean value of the ratio of weight-for-height(W/H ratio) was $102.3{\pm}11.3%$ in all males, and $105.2{\pm}103.6%$ in all females. The difference of the values between males and females showed statistical significance(P<0.001). The mean value of W/H ratio in all the insureds was $103.8{\pm}12.9%$. In each age group, the mean value of female was higher than that of male without exception(P<0.001). The mean value of both sexes in each age group showed gradual increase with age except for the age group over 50(P<0.001). 2. The incidences of the average weighted, overweighted and underweighted lives were respectively 91.6% in all males, 84.2% in all females(P<0.001); 7.9% in all males, 15.4% in all females(P<0.001); 0.5% in all males, 0.4% in all females(P>0.05). The incidences of average weighted, overweighted and underweighted lives in all the insureds were respectively 87.6%, 12.0% and 0.5%. The incidence of the average weighted lives in male in each age group was always higher than that in female with the exception of the age group below 19(P<0.001), whereas the incidence of the overweighted lives in male in each age group was always lower than that in female(P<0.05 in the age group below 19, P<0.001 in the other age groups). The incidence of average weighted lives of both sexes in each age group showed gradual decrease with age from the second to fifth decade(P<0.001), whereas the incidence of the overweighted lives of both sexes in each age group showed gradual increase with age from the second to fifth decade(P<0.001). 3. The relative frequency distribution polygons of W/H ratio of both sexes drawn in a pair on one coordinate plane revealed lying in juxtaposition each other horizontally and showed the shifting of female's polygon to male's one toward the direction of greater value of W/H ratio at a short distance which increased gradually with age. 4. Correlations between both sexes and among age groups relating to W/H ratios of the insureds seem to be a physiological phenomenon of body build and should be considered on the rating of the build. Author prepared a rating table of build based on the correlations above menthioned. Some gradients by sex and age in the rating table of build are organized; in female group, the ratings of 0, 30-50, 50-100 and 100-D are to calculate by the build with W/H ratio of 80-125%, $126{\sim}145%,\;146{\sim}165%$ and over 166% respectively in the age group of 29 or under, by the build with W/H ratio of $80{\sim}130%,\;131{\sim}150%,\;151{\sim}170%$ and over 171% respectively in the age group of $30{\sim}59$, and by the build with W/H ratio of $80{\sim}135%,\;136{\sim}155%,\;156{\sim}175%$ and over 176% respectively in the age group of 60 or over. In male group, the ratings of 0, $30{\sim}50$, 50-100, and 100-D are to calculate by the build with W/H ratio of $80{\sim}120%,\;121{\sim}140%,\;141{\sim}160%$ and over 161% respectively in all ages. Of under weighted lives, in both sexes, the ratings of 30-50 and 50-D are to calculate by the build with W/H ratio of $76{\sim}79%$ and under 75% respectively. The results of the ratings according to a rating table by author were as follows: The incidence of the ratings of 0, 30-50, 50-100 and 100-D showed no difference between male and female. The incidence of the ratings of 0(indicating the average weighted lives) showed gradual decrease with age and the incidence of the ratings of 30-50 and 50-100(indicating the overweighted lives) showed gradual increase with age. These results are thought to be considerably reasonable because the incidence of the builds in each age group is supposed to have no difference by sex and the incidence of the overweighted lives would increase with age.

In this study an attempt has been made to throw some light on the problem of the mandibular third molar on measurement made from 302 orthopantomograms of patients at the age of 8 to 20 years. The following conclusions were drawn on the basis of the present study. 1. The amount of growth from the lower first molar to the anterior border of the ramus from 8 years to 14 years was 7.9mm in the male and 7.5mm in the female. The growth from 15years 20 years was 4.5mm in the male and 2.6mm in the female. 2. The growth from the lower first molar to the posterior border of the ramus from 8 years to 14 years was 10mm in the male and 9.8mm in the female. The growth occurred after that was 5.8mm in the male and 2.0mm in the female. 3. The difference between A and C measurements for the various age groups remained fairly constant in the male and female.

The aim of this study was to investigate the variation in shape, size and area of the pharynx and adenoids, and to analyze the relationship between pharyngeal cavity and upper facial cranium which effected on morphology of those parts in Korean. Age changes and sex differences in those areas were comprised in this study. Materials included 272 lateral cephalograms, which were divided into 4 groups by age; (1) 7-year-old group consisted of 29 males and 30 females, (2) 12-year-old group consisted of 30 males and 30 females, (3) 17-year-old group consisted of 30 males and 40 females, (4) 20-year-old group consisted of 37 males and 46 females. In subjects each variable was measured and evaluated statistically introducing 17 reference points and 17 reference lines respectively. Conclusions from this study were as follows. 1. Linear measurements of the bony nasopharynx revealed that the depth and height were larger in male than those in female in 17 and 20-year-old groups. 2. Linear measurements of the upper facial cranium were larger in male than those in female in all age groups. 3. Angular measurements of the bony nasopharynx and upper facial cranium did not show, on an average, sex differences in each age group. 4. As regards area of the bony nasopharynx, it increased gradually with age in both sexes. And the area was greater in male than that in female in 17 and 20-year old groups. 5. There were sex differences in area of the adenoids of which the area was larger in male than that in female in 17 and 20-year-old groups. And the area reached a peak at 17-year-old group in male and at 12 year-old group in female. 6. Area of the pharyngeal cavity increased gradually with age in both sexes, but no sex differences were noted in each age group. 7. Rate of area of the adenoids to that of the pharyngeal cavity decreased continually with age, and no sex differences were noted in all age groups. 8. In amounts and its differences of the growth, there were sex differences in the posterior upper facial height, and were not in area of the bony nasopharynx, pharyngeal cavity and adenoids in each age group.

Experiments were performed to determine age-associated changes in ornithine decarboxylase (ODC) gene and Ha-ras cellular oncogene expression in tissues of female rats. In the kidney, ODC mRNA levels did not show age-associated changes, while ODC enzyme activities were decreased with advancing age from 3 to 10 months. These results suggest that post-transcriptional mechanism (s) are involved in the age-dependent decrease in renal ODC enzyme activity. In addition, we found no correlation between testosterone-induced renal ODC expression and DNA methylation pattern. Ha-ras mRNA levels in brain decreased as animals aged from 3 to 6 months, while renal Ha-ras mRNA levels were not influenced by age. Results demonstrate the age-dependent expression of Ha-ras in a tissue-specific manner.

For design of early childhood children's footwear, this study was to analyze the properties of their foot. This study was performed in 200 male and 200 female early childhood children from 3 and 6 years old lived in susan urban area. There were measured 17 items of the foot and calculated 4 indexs for analysis. The result was as follows; 1 The growth rate differs from the sites of a foot. According to the growth of age, early childhood children's foot are more slender. 2. The average of foot print angle is $15~27^{\circ}$ and it is flat. Among the age groups, the numbers of 4 kinds of foot print angle are different siginificantly. 3. The average of metatarso phalanx angle is $174~178^{\circ}$ that is higher than adults'. 4. There are no significant difference between male children's foot and female childen's one except tarsal circumference and tarsal height. Tarsal part of male children is higher and ticket than female children's. 5. Because some of 3~6 age groups belong to the one foot length group, we should consider the age properties of foot in order to design footwears. When the size of footwear is divided by only foot length, the ranges of another measurements are larger than the range of foot length.

This study tried to compare and analyze the body measurements of female adults in China by various age groups. As for the study method, direct and anthropometric measurements were used on the 357 female subjects living in Yenbien and Harbin, China, consisting of 122 women in their 20's, 114 women in their 40's, and 121 women in their 60's. The results were as follows: 1. The comparison of major body measurements between Korean Chinese and Korean in land indicated that the former were shorter and plumper than the latter. Those groups in their 60's did not show any significant difference in height related measurements and revealed less differences in body measurements comparing to other age groups. 2 The comparison of Chinese anthropometric measurements among age groups of Korean Chinese indicated that, higher the age, shorter the height measurements, the leg length shorter, the upper-half body length longer, and the chest drooping due to the breast descent. 3. The comparison of indirect measurements among age groups of Koreans Chinese indicated that those in their 60's showed many items of big discrepancies in comparison with those in their 20's or 40's, with wide gap in discrepancies, thus resulting in large differences among individuals.

The MRI (magnetic resonance imaging) volumetric analysis of the brain was performed in 59 healthy elderly Koreans (aged 62-76 years; 34 male, 25 female) to investigate whether the previously reported significant correlations between body height and brain volumes in the young aged Koreans (20's) still exist in the old aged Koreans (60's and 70's). Unlike previously reported significant correlations in the young aged Koreans, neither the correlation between whole brain volume and body height in male nor the correlation between cerebellar volume and body height in female show any significance in the old aged Koreans. The significant correlation between body height and whole brain volume was still observed when both male and female data were combined (r=0.27, P<0.05), but the correlation coef-ficient and the level of significance markedly decreased from those of previously reported Korean youth data (r=0.67, P<0.01). Simple linear regression analysis shows decrease of explanatory power of height (measured in $r^2$) from 44% in the youth group to 7% in the old age group on the variance of whole brain volume. Multiple linear regression analysis shows that age and sex, rather than height, are major explanatory variables for whole brain volume in the old aged Koreans. The loss of correlations in the aged group is suspected to be mainly due to age related brain volume changes.
