The purpose of this research of this research was to survey the health of 181 male and 130 female students at K University in Chunganm from June 1 to June 23, 2001. It analyzed the students’dietary behaviors, life styles and perceived body shapes and the correlation of these factors to the health condition of the students surveyed. The results of the survey are summarized as follows. The average nutrition knowledge score (out of a possible 20 points), dietary attitudes score (out of a possible 50 points) and dietary habits score (out of a possible 30 points) were 8.66, 33.14 and 19.02 for males, and 9.99, 32.64, and 19.05 for females, respectively. The percentages of those who smoked, drank, smoked and drank and exercised regularly were 55.2, 92.8, 54.1, 82.9% for males, and 6.9, 91.5, 6.9, 63.1 for females, respectively. A significantly higher proportion of males smoked, drank, and exercised as compared to females (p<0.001). The percentages of students who were underweight, normal or overweight by BMI were 5.0, 79.0 and 16.0 for males, and 20.0, 78.5 and 1.5 for females, respectively. Fifty percent of females indicated that they felt they were obese, versus only 31.1% of males. Half of the females thought they were fattish, while only 31.1% of males thought that. Seventy-six point nine percent of females and 61.9% of males, more females than males, were dissatisfied with their weights. The health scores (the higher the point, the better the health condition) of the females (44.17) were significantly lower than those of the males (47.17) (p<0.001). A stepwise multiple regression analysis with health scores as the dependent variable and other scores as independent variables, indicated that the health scores of males were highly correlated with satisfaction with his body weight, smoking and drinking, and perceived body shape, whereas the females’health scores were highly correlated with obesity level, satisfaction with her body weight, and smoking and drinking.

This study investigates the factors associated with adolescent females' sexual behavior. Results from 390 adolescent females reveal that dating atmosphere was the strongest and the most influential risk factor predicting adolescent females sexual behavior, which has been a neglected variable in the research of adolescent sexual behavior. Age and similarity of sexual attitude with her dating partner, in addition to the dating experience had very significant impacts on highly sexually experienced adolescent females' sexual behavior. Adolescent females with low sexual experiences were significantly affected by similarity of sexual attitude with dating partner, siblings, and peers, her own attitude, age, and dating atmosphere. The findings from this study also indicate that parental supervision, dating atmosphere, respondent's sexual attitude, love for partner, and communication with parents on sexual issues were significant factors for determining adolescent females' sexual involvement.

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.

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.

An experiment was conducted to study the PWC(Physical work capacity) of Korean females. A submaximal technique using the Ramp test protocol was used to measure the PWC. A cycle ergometer and a treadmill were used to assess the workload. The estimated PWCs of Korean females in terms of maximum oxygen consumption(${\dot{V}}o_2Max$) from the experiment were 1818.79ml/min in cycle ergometer test and 2076.33ml/min in treadmill test, respectively. The PWCs of Korean females were compared with those of western and oriental females. The PWCs of Korean females were about 2/3 of Korean males, 72%-82% of western females, and about 118% of South-east Asian females after applying age correction factor.

A series of no-choice olfactory response tests using water pre-conditioned with females, with intact and surgically removed ventral glands, at various reproductive states were conducted to determine whether male Hynobius leechii discriminates among females in different reproductive states based on chemical cues. Similarly, ventral gland extracts were tested, and ventral glands were examined histologically. Males’ responses to putative odors of females in four (ovulating, ovulated, ovipositing, and oviposited) reproductive states were independently measured by: i) the latency time to initiate male behavioral response, ii) the arrival time at a fixed point of putative odor source, and iii) the staying time close to the odor point source. Male salamanders showed significant olfactory responses to recently ovulated and ovipositing female odors by quickly arriving at odor sources and staying longer at the origin of the source, but the olfactory responses to the earlier staged ovulating females and the later stage of already oviposited females were not different from controls. Olfactory responses of test males to water preconditioned by intact females or females with ventral glands excised were not different. In addition, ventral gland extracts did not induce significant olfactory responses of test males although the lumens of alveoli in ventral glands of oviposited females were smaller than those of ovulated females. These results indicate that male H. leechii recognizes ovulated and ovipositing females based on chemical cues released but not from the ventral glands.

Purpose: : The purpose of this study was to evaluate the intrauterine insemination (IUI) success rate and to define the variables for predicting success. Methods: The secondary data analysis was used with data collected from infertile females who underwent IUI in Fertility and IVF (In Vitro Fertilization) clinics, who benefited from the 'National Medical-aid Program for ART (assisted reproductive technology) in 2016', in which the data of 34,920 IUI cases were retrospectively reviewed. The primary outcome measure was the clinical pregnancy rate in elderly and young infertile females. Data were analyzed by descriptive statistics, χ2 test and logistic regression. Results: The pregnancy rate was 12.1% (2,095 cases) in elderly infertile females and 15.6% in young infertile females (2,758 cases) (χ2 = 87.90, p< .001). Using the logistic regression analysis, clinical pregnancy was positively associated with the ovulatory factor (OR= 1.48, p< .001) and male factor (OR= 1.19, p< .05) in elderly infertile females. It was positively associated with the ovulatory factor (OR= 1.30, p= .001) and the peritoneal cavity factor (OR= 0.58, p< .05) in young infertile females. Conclusion: Our results indicate that the pregnancy rate in young infertile females was higher than that in old infertile females, and the IUI is the effective option in pregnancies in all ages with infertility due to the ovulatory factor. Additionally, further studies are necessary to fully describe pregnancy experiences for all the infertile females.

The nutritional status of middle-aged overweight and control normal subjects were evaluated for the purpose of providing the background information of the degenerative disease control. A survey was conducted with 293 healthy subjects (121 males and 172 females) between the ages 40-64. The average BMI (body mass index) of male subjects was 24.5 $\pm2.75$, and that of females was 23.5 $\pm2.87$. The average values of WHR (waist-hip ratio) were 0.88 $\pm0.04$, for males and 0.82 $\pm0.07$, for females. The normal BMI group (BMI 18.5-22.9) comprised 28.9% of males and 47.1% of females. The percentage of overweight subjects (BMI 23-24.9) was 26.4% of males and 30.8% of females. The obese group (BMI ＞ 25) was 44.6% of males ana 22.1% of females, showing the greater rate of obese state among male subjects. The average energy intakes were 76.6 $\pm14.9$% for males and 77.8 $\pm12.6$, % for females, protein intakes were 108.0 $\pm24.6$% for males and 111.2 $\pm22.7$, % for females of the RDA levels. The average intakes of other nutrients were above the 75% of RDA levels except calcium. The average nutrient intakes of the three subgroups according to their BMI values were not different for both males and females. There were weak correlations between obesity and blood biochemical indices. There were positive correlations between BMI or WHR and hemoglobin, hematocrit, fasting glucose, total cholesterol, triglyceride, AST or ALT. There were negative correlations between BMI or WHR and HDL-cholesterol. These results suggest that the obesity rate of middle-aged is an influential factor of chronic disease. The middle-aged subjects of this study with higher educational and socioeconomic background tend to have desirable nutrition knowledge and attitude, but the application of their knowledge or attitude was relatively poor.

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.

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%.
