The frequencies of finger print patterns and the pattern intensity index among 2, 925 Koreans (804 males, 2, 121 females) are analyzed. Total finger ridge counts was calculated for 776 Koreans (426 males and 350 females). Comparisons are made with results among other racial populations in a review of the literature. Certain differences exist between males and females in both qualitative (finger print pattern) and quantitative (total ridge count) dermatoglyphic traits. Males have higher frequences of whorls (53.6% for males, 45.7% for females), and radial loops (2.9% for males, 2.2% for females), while the frequencies of archs (1.9% for males, 2.9% for females) and ulnar loops (41.6% for males, 49.2% for females) are higher in females. The pattern intensity index for males (15.2) was higher than that for females (14.3). The mean of the total ridge count was higher (140.4$\\pm$41.2) in males than in females (129.8$\\pm$40.6). There was no correlation between total ridge count and IQ (r=-0.0027, N=343). Total ridge count among different racial groups was found to vary slightly.

This study investigated elderly winter wearing habits and self-identified thermal tolerance in order to compare differences between older males and older females. We surveyed 269 participants: 119 males (age $76.9{\pm}5.9yr$) and 150 females (age $76.1{\pm}5.7yr$). Thirty one questionnaires were used: Self-identified cold and heat tolerance, clothing behavior, lifestyles related to the cold and health care, etc. High percentage of respondents (both males and females) felt vulnerable to the cold. The total number of outdoor clothes were $9.6{\pm}1.6$ and $10.6{\pm}1.6$ in males and females, respectively (p<.05). Wearing frequencies for thermal underwear were 84.0% and 82.4% in males and females, respectively. The using percentage of auxiliary heating devices was higher in females compared to males (p<.01). Males felt more cold in the head and face compared to females (p<.01). Self-identified cold tolerance had negative relationships with the total number of winter outdoor clothes for both males (r=-0.260) and females (r=-0.222) (p<.01). The perceived old age for both males and females was 72.4 yr. Sex differences should be considered when developing guidelines for winter clothing behavior for the elderly and educating them on how to improve health and cold tolerance.

Using Random Sampling, the authors measured the body heights and weights of 31,151 persons - 17,102 in males and 14,049 in females from metropolitan, urban and rural areas between 6 to over 80 year old - for the purpose of investigating the type and the actual condition of the Korean's growth and development. At first, on the basis of the results, the authors measured the growth and development, various kinds of physiques, nutritional index of the 6 to 20s age group. Second, the authors presented the standard body weight of males and females by their body height, who were in the end of their growth (20-29 age group). Third, the authors calculated and presented the normal adapted body weight of the age group who were over 30 age after the growth had been completed. Forth, the author presented the obesity rate of the adults over 20 years old by body mass index. Finally, the authors compared chronological change of the Koreans' body heights and body weights with the results of other researchers. 1. Body Measurement Rapid growth, in terms of body height, which is described by a straight line on a growth curve has been observed among males in the ages 6-13 and among females 6-14. That growth curve turned out to be slower among the people of higher ages by both sexes. The cross-over occurred in both sexes at 11-14. The highest growth rate for a year is at 13-16 for males and 11-13 for females. This indicates that females enter a rapidly growing stage 2 years earlier than males. 2. Various Physiques and Nutritional Index Rapid growth, in terms of Relative Body Weight Index, which is described by a straight line, has been observed among males in the ages 6-16 and females in the ages 6-14. The cross-over occurred in both sexes 12.5-14.5 age in the adolescencent period. Whereupon females outgrow males. The Roher Index displayed more good value in case of females than male and in the adolescent period, the level of fullness is lower than after the completion of development. The Kaup Indices of both sexes increase with age. The index is less than 2.0 for males in 6-14 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state4 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state Body Mass Index is less than 20 for males 6-14 age group and for females in 6-13 age group. In the case of the higher age group, that index maintains a normal state.

Purpose: Photogrammetry has been introduced as an alternative to direct measurement to obtain facial distances for a variety of anthropometric applications. The aim of this study is to establish morphological and functional value of an eye in Korean youths using specially designed computer software with digital photographic images. Methods: Authors measured anthropometry of an eye in Korean youths 1,449 individuals(622 males, 827 females) and analyzed stastically them. Results: The mean measurements are as follows. The diameter of cornea was $11.6{\pm}0.9mm$ in males and $11.3{\pm}0.9mm$ in females. The vertical dimension of palpebral fissure was $7.4{\pm}1.7mm$ in males and $8.2{\pm}1.6mm$ in females. The intercanthal width was $35.8{\pm}3.2mm$ in males and $34.4{\pm}2.9mm$ in females. The biocular width was $90.4{\pm}5.7mm$ in males and $87.4{\pm}5.3mm$ in females. The endocantion-superior margin of palpebral fissure distance was $12.7{\pm}1.4mm$ in males and $11.6{\pm}1.4mm$ in females. The horizontal dimension of palpebral fissure was $28.5{\pm}2.2mm$ in males and $27.4{\pm}1.9mm$ in females. The slant of palpebral fissure was $10.7{\pm}2.6^{\circ}$ in males and $11.3{\pm}3.0^{\circ}$ in females. The height of upper eyelid was $10.6{\pm}2.3mm$ in males and $10.7{\pm}2.3mm$ in females. The width of double fold was $2.0{\pm}0.7mm$ in males and $1.9{\pm}0.6mm$ in females. A double fold was seen in 21.9% of males and 44.9% of females. The most frequent shape of the double fold was type IV. The most common type of epicanthal fold was type III in both males and females. Conclusion: Photogrammetic measurement of large population using specially designed software could offer reliable data and these data could be useful reference for preoperative consultation, surgical planning and anthropometic study of eye.

The present study examines the role of commitment in dating relationships. Using 354 university students, the data show that commitment is positively related to premarital sexual behavior, especially for highly experienced females. The development of dating relations is significantly related to the level of commitment for both males and females and the differences between groups are more obvious for female students. Commitment increases as duration of dating relations increases. While females generally show higher commitment at more advanced dating relationships than males, males indicate higher commitment at beginning stages than females. The implications of these findings are dicussed.

This study was conducted to assess the biochemical nutritional status of 310 elderly(males: 130, females : 180) residing in Puchon City. Subjects were apparently healthy, home staying and aged over 60. Average height of males and females were 163.2cm and 148.5cm, respectively. Female aged over 80 showed 148.5cm, which was significantly lower than that of group aged 60~69. The rate of moderate obesity for males assessed with BMI($\geq$27) was 7.7%, and 23.4% for females. The hypertension rate assessed by SBP($\geq$160mmHg) was 8.0% and 10.5% for males and females, respectively. The proportion of hypertension with indice of DBP( 95mmHg) was 9.4% and 23.4%. The lower concentration of Hb(males: <13g/dl, females: <12g/dl) occurred in 10.7% for males and 11.7% for females. No one except a few was found with protein deficiency assessed with serum albumin, serum protein and the ratio of urinary nitrogen to creatinin. Twenty five percent of males and 35.2% of females belonged to hypercholesterolemia($\geq$ 240mg/dl). The proportion of elderly whose fasting blood sugar was higher than 140mg/dl was 23.7% and 23.2%.

Fingerprints of 100 New Zealand-Samoan males and 93 females have been analyzed. Whorls are more numerous in fingerprint females (65.6%) than in males (55.6%). The index of pattern intensity displays a higher value in females (16.49) than in males (15.48). The bimanual differences both in males and females are not statistically significant for the occurrence of patterns on the digits of the right and left hands. Also the difference between both sexes for the occurrence of patterns is not statistically significant. Incidences of actual symmetry on homologous digits represented 78.2% in males and 85.8% in females. The mean total ridge counts showed $175.7{\pm}54.6$ ($M{\pm}SD$) in males and $171.6\{pm}49.8$ ($M{\pm}SD$) in females, respectively. Conclusively, this study shows that the New Zealand-Samoans are closely related to the Mongoloids in quantitative dermatoglyphics.

In this study, we investigated the growth rate on the basis of the sex and the year among the subjects of the licensed dental technicians from the year 1970 to 2003 in Korea. In line with this investigation, this study aims to provide a basic material with regard to the state of dental technician workforce by sex and to suggest a need to reassignment of workforce by sex in accordance with the specific job description. The results of the study are as follows; First, among the licensed dental technicians from 1970 to 2003, males came to 11,589 and females, 5,976, which shows the number of males are 1.9 times higher than that of females. To put the mean sexual composite from 1970 to 2003, male was 82.9% and female 17.1%, indicating the number of males are 4.8 higher than that of females. Second, Of the mean increasing rate until the year 2003 in contrast to 1970, male was about 351 and female was about 181, which shows the number of males increased 1.94 times higher than the females. Comparing to the mean increasing rate of the last year, female came to 25.56% and male 10.73%, which reveals that the females were about 2.4 times higher than the males. In the case of the growth rate, females increased by 1,196,20 times and the males, 26,41. As a result the growth of females are about 45.3 times higher than the males. Third, in the case of the growth rate from 1980 to 2003, females came to 47.85 times and males 9.16, which shows the growth rate of the females was about 5.2 times higher than the males. In contrast to the year 1987, the growth rate until 2003 shows that the females came to 5,13 times and the males 2.70, which indicates the growth rate of females was about 1.9 times higher than males. Fourth, Compared to the year 1990, the growth rate until 2003 shows that females came to 3.40 times and males 2.03 indicating the growth rate of the females was about 1.7 times higher than males. In contrast to the year 2000, the growth rate till 2003 shows that females was 1,34 times and males 1.15 times increased. Fifth, the ratio of sex by the year among the licensed dental technicians is as follows; ratio of male to female in 1970 was 91.2 to 1. In 2003 the ratio came to 2.0 to 1. The number of growth by sex in 1970 came to 24.0 males to 1 female. But the figure was equalled in 2003.

Several aspects of the conscious about somatotype were analized for the young females and the middle-aged womenhood of Korea. the questionaires were sent to sample of students of university and the middle-age womenhood in Kwangju. the data from 233 respondants were analysed in using frequency, crosstabs and t-test. The results were as follows: 1. Korean young females tend to have shorter and slimmer in trunk, taller in height and lighter in weight than somatotype of the middle-aged women. 2. Of the trouble of somatotype, young females tend to have much the trouble about the thickness of thigh and the middle-aged women tend to have much the trouble about the thickness of waist, hip. 3. Korean young females tend to have much the trouble of somatotype than that of the middle-aged women. 4. And then, most young female had strong aspiration to be slim about somatotype than that of middle-aged women.

The present study was conducted to investigate the relation of eating behavior and food intake to 534 adolescents' obesity indices. Group means of relative body weight (RBW) were 93.66 for males and 97.12 for females. Body mass index(BMI) were 20.39 for males and 20.41 for females. Respondents were divided into 3 groups on the basis of RBW as an obesity index. Astonishingly, 44.76% of total respondents were underweight and 12.92% overweight and obese. 64.54% of respondents usually skipped their breakfasts and 24.23% their dinners. More males did not have their breakfasts than females. In contrast, more females skipped their dinners than males. A significant difference was found between males and females in their eating habits(p<.001) that should be changed. As their undesirable eating habits, males pointed out 'skipping meals', while females stressed 'overeating'. There were more overeating respondents in the overweight group, while more respondents skipping their meals were found in the underweight group. Many females(72.79%) and males(52.78%) tended to alternate consistently overeating and fasting to lose weight. The most important reason for losing weight was to improve their appearance(61.12%). In addition, nutrient score indices of respondents were very low with a mean of 33.39. Only 42.13% of total respondents showed good nutrient score indices. More males ate meat, bean, white vegetables, potato and fat than females(p<.05), whereas more females ate bread, rice cake and fruit than males(p<.01). Among the 3 groups -overweight, normal weight and underweight groups, overweight group was the most eaters of meat, fish, egg and milk; underweight group was the least eaters of them.
