  • The purpose of this study was to find the charateristics of Sasang Constitution, Soeumin, Soyangin and Taeumin from the result of body Circumference ratio. In this study, 324 data of body circumference were measured by body composition analysis. We analyzed the body circumference ratio by Sasang Constitution, Soeumin, Soyangin and Taeumin. Taeumin's body circumference were significantly higher than those of Soeumin and Soyangin. Soyangin's body circumference was significantly higher than that of Soeumin. Male Taeumin's muscle circumference were significantly higher than those of male Soyangin and male Soeumin. Female Taeumin's fat thickness were significantly higher than those of female Soyangin and female Soeumin. Male Soeumin's ratio of hip circumference and neck circumference to abdomen circumference were significantly higher than those of male Taeumin and male Soyangin. Male Taeumin's ratio of hip circumference to abdomen circumference were significantly lower than those of male Soeumin and male Soyangin. Female Taeumin's ratio of hip circumference and chest circumference to abdomen circumference were significantly lower than those of female Taeumin and female Soyangin. In body circumference ratio, Soyangin had no difference among Sasang Constitution. In body circumference ratio, male Soeumin had big lower area ratio and big upper area ratio to lower-middle area. Male Taeumin had big lower-middle area ratio to lower area. Female Taeumin had big lower-middle area ratio to lower area and upper-middle area.

  • This study was carried out to investigate the clinical characteristics of 78 diabetics by body fat distribution pattern. It was based on the survey of nutritional status, anthropometric measurements and serum components of the patients. The results were as follows: the average ages of male and female subjects were 57.1, and that of female subjects was 58.9, respectively. The average diabetic durations of male and female subjects were 4.8 and 5.9 years, respectively. In male, the ratio of upper body obese subject was 62.5% and the lower body obese subjects was 37.5%, while those of female were 69.4% and 30.6%, respectively. In nutrient intake state, there was no significant difference between male and female subjects, but calory intake of upper body obese subjects was difference between male and female subjects, but calory intake of upper body obese subjects was tend to be higher in both male and female subjects. among the three major nutrients/calory ratio, protein/calory ratio was significantly lower in the male upper body obese subjects than in the male lower body obese subjects. Since weight, circumference of arm and waist, waist hip ratio(WHR) of both male and female subjects, body muscle mass(BMM) of male subjects and body mass index (BMI) of female subjects were significantly higher in upper body obese group, upper body obese subjects represented ore fat than lower body obese subjects. In male subjects, hemoglobin(Hb), A/G of upper body obese subjects were lower than the standard value, but there was no significant difference in the serum components between two subjects. In female subjects, Hb and A/G of lower body obese subjects were lower than those of the normal subjects, but Hb and Ht of upper body obese subjects were significantly higher than those of the lower body obese subjects.

  • To evaluate fetal sex-hormonal status before delivery, testosterone and follicle stimulating normone(FSH) levels were measured in 64 amniotic fluid samples at midgestation by radioimmunoassay method. The mean concentration of testosterone in amniotic fluid of 37 cases carrying male fetus was 90.7 pg/ml and 27 cases carrying female fetus was 62.3 pg/ml. The mean :amniotic fluid FSH concentration of male fetus was 1.15 mIU/ml and of female fetus was 11.98 mIU/ml. The amniotic fluid testoserone and FSH concentrations had statistical difference between male and female fetuses. The ratio of testosterone over FSH in the amniotic fluid was 231.2 in male, 9.8 in female respectively and very significant difference was noticed. The levels of testosterone/FSH greater than 25 were found over 92% of male fetus and lesser than 25 were found over 92% female fetus. Measurement of testosterone and FSH especially testosterone/FSH ratio in amniotic fluid in midgestation may be an adjunct to other method of fetal sex determination.

  • The pattern of variations in cone sex ratio and pollen traits such as pollen number and size was examined for two years in populations of red pines In Korea. We evaluated; (1) the relationship between tree size and cone sex ratio, (2) the relationship between year and cone sex ratio, and (3) the relationship between cone sex ratio and pollen traits. Larger trees in height and circumference at breast height produced more male as well as female cones. However, cone sex ratio was independent of these plant sizes. Across the two populations, both female cone numbers per tree and male cone numbers per new shoot increased 2.2 and 1.2 times, respectively, in 1999 compared to 1998, while the yearly pattern of male cone-bearing shoots per tree differed significantly between populations. Thus, cone sex ratio varied significantly between years in one of the two populations. Pollen traits such as the number of pollen grains and diameter did not vary significantly among populations. Pollen diameter and grain numbers per male cone were significantly negatively correlated with the cone sex ratio in two populations and one population, respectively. Trees which stopped female cone production in the first year and those which produced female cones in both years differed in the cone sex ratio and pollen size in the second year. The long duration of one reproductive episode and the potential of masting in red pines emphasize the need to conduct long-term studies on the dynamics of cone production, cone sex ratio, and simultaneous changes in pollen traits in red pines.

  • 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.

  • For the purpose of preparing the basic data for further cancer epidemiologic study and cancer patients control, we conducted the analysis on the degree and structure of deaths from cancer in metropolitan areas of Korea with 7,934 certified cancer deaths records of Seoul, Pusan, Taegu and Incheon in 1982. The analyzed results were as follows: 1) The total number of cancer deaths in metropolitan areas were 7,934 (male: 4,749, female: 3,185) as 14.1% of deaths from all causes in the same area. 2) The rate of physician's certification on cancer deaths was 77.4% and most of cancer deaths (84.4%) occured at their home. 3) Cancer specific death rate was 51.7 per 100.000 population (male: 62.9, female: 41.9) and age-adjusted cancer death rate was 82.4 in male and 51.6 in female per 100,000 population. And the difference was statistically significant (p< 0.01). 4) Age-specific cancer death rate was generally increased with age and most of cancer deaths (male: 75% , female: 65%) occurred from 45 to 74 years old. 5) The first three orders of cancer site were stomach (32.7%), liver (28.8%), lung (11.7%) in male and stomach (30.6%), uterus (18.4%), liver (13.8%) in female. And the relative frequency of these three cancer sites among total cancer deaths was corresponded to 73.2% in male and 62.8% in female. 6) The ratio of male to female cancer death rate was 1.5:1. And the ratio was aboye 3.0 in esophagus, liver, larynx, bladder cancer and the ratio was similar to 1.0 in stomach, pancreas, leukemia, brain, colon cancer, but the ratio was reversed in gall bladder and bile duct, and thyroid cancer.

  • This study was performed to investigate the effect of mixed rearing of male and female chickens on the stress response in Korean native chickens. To identify the degree of the stress response, heterophil-lymphocyte ratio (H/L ratio), heat shock protein genes (HSPs) expression, and intracellular nuclear DNA damage rate were analyzed before and after the mixed rearing of male and female chickens. The results showed that the H/L ratio of chickens after mixing males and females was more than thrice as higher than before mixing (P<0.001), but the differences between males and females were not significant. HSP-70, HSP90-α, and HSP90-β expression levels were 2.5 to 3.4 times higher after mixing male and female chickens, compared to before mixing (P<0.01). In the mixed rearing of male and female chickens, the increase in HSPs expression in females was higher than in males. Comet indicators in intracellular DNA damage rate analysis showed a significant increase after mixing male and female chickens compared to before mixing (P<0.001). However, there was no significant difference between males and females with respect to DNA damage rate. Taken together, these results suggest that male and female mixed rearing acts as a strong external stressor in both male and female chickens.

  • Purpose: This study was aimed to determine the optimum low-density lipoprotein : high-density lipoprotein-cholesterol (LDL : HDL-C) ratio for predicting coronary heart disease(CHD) in Korean people. Methods: It was analyzed this data of 5,431 adults who had undergone health examinations in a hospital in Gyeonggi-do between January 2006 and December 2007. The covariation of the coronary risk factors such as age, HbA1C, systolic blood pressure(SBP), and waist-to-stature ratio(WSR) were analyzed by using logistic regression analysis. Results: The LDL : HDL-C ratio in the male and female groups was mostly distributed between 1.5 and 4.0. The LDL : HDL-C ratio was the most significant cholesterol-related parameter influencing CHD (male: B = .306, p = .054, female : B = .940, p = .010), followed by LDL-C and total cholesterol. It was observed a sharp increase in the odds ratios for LDL : HDL-C ratios of 2.25 - 2.50(male) and 2.00 - 2.25(female). A significant difference was observed in both male(2.25 : $x^2$ = 2.494, p = .072) and female(2.00 : $x^2$ = 413.742, p = .000) groups. Conclusion: The risk level of CHD was set to 2.25 for males and 2.00 for females. Therefore, the optimum LDL : HDL-C ratio for Koreans should be far lower than that for the people in western countries.

  • The purpose of this study were to investigate the differences between female and male basketball players in knee neuromuscular biomechanical factors during basketball rebound jump. Twelve high school female ($17.9{\pm}0.8years$) and twelve male ($19.0{\pm}1.6years$) basketball players rebound jumped for maximal vertical height to sufficiently stress the anterior cruciate ligament. Kinematic and ground reaction data were collected and combined with inverse dynamics to estimate the knee extensor and abductor torque. The EMG data from the biceps femoris and rectus femoris was used to estimate the ratio of quadriceps muscle activity. Female athletes showed more reduced knee flexion at foot contact, more increased knee abduction, extensor and abductor knee joint torque at foot contact, and quadriceps ratio at stance phase than those of male athletes. In conclusion, Female athletes showed differences in knee neuromuscular biomechanical factors than male athletes during basketball rebound jump.

  • The effect of sex ratio on behavior and welfare indexes in broiler chickens was investigated. Five variants of the sex ratio (male to female), namely, 100:0 (T1), 75:25 (T2), 50:50 (T3), 25:75 (T4) and 0:100 (T5) were tested in broilers between the ages of 7 to 35 days. It was found that the most common behavior in all sex ratios was resting behavior, ranging over 74.4 % of total behavioral frequency. The ranges of other behavior traits of total behavior traits were as follows: pecking, 5.4 to 23.1 %; standing, 1.8 to 24.8 %, and moving, 0.6 to 11.5 %. The behavioral frequency of resting, pecking, standing and moving were not affected by the sex ratio and between male and female. But the percentage of pecking, resting and moving behavioral frequency was significantly different by the age of birds (P<0.05). Age of birds had no effect on standing behavioral frequency. It seems that gait, food pad and hock burn score were no affect by sex ratio but tend to decreased in female than male. Claw length of 21 and 35 days was not affected by sex ratio and between male and female. The duration of tonic immobility (TI- reaction) was tend to decreased age of 21 than 35 days, and female than male. Both male and female of the study, hock burn score, claw length and TI-reaction were tend to lower in T4 than other treatments. The results suggest that, when male and female broilers are reared together, sex ratio can influence broiler welfare indexes in this study.
