Background: Females generally have a lower pain and temporal summation threshold than men. However, the results of studies designed to evaluate gender differences in the thresholds of heat pain and the temporal summation have been inconsistent. Newly developed device, CHEPS (Contact Heat Evoked Potential Stimulation) model of PATHWAY, have superiority on its fast rise and return time in temperature. Therefore we investigated gender differences in heat pain and temporal summation threshold. Methods: Forty healthy volunteers (20 males and 20 females) were enrolled in this study. A thermode was applied to the volar side of each volunteer's left forearm and heat pain and the temporal summation threshold was then measured. The heat pain threshold was estimated using the staircase method by starting from $36^{\circ}C$ and then increasing the temperature in $0.5^{\circ}C$ increments. The temporal summation threshold was estimated by applying five successive stimulation of the same temperature starting at $2^{\circ}C$ lower than the heat pain threshold and then increasing the temperature in $0.5^{\circ}C$ increments. Results: The mean heat pain thresholds was found to be $41.63{\pm}1.63^{\circ}C$ for males and $41.60{\pm}1.84^{\circ}C$ for females and the temporal summation thresholds were found to be $40.83{\pm}1.64^{\circ}C$ for males and $40.77{\pm}1.93^{\circ}C$ for females. The differences between males and females were not statistically significant. Conclusions: The result of this study suggested that there are no gender differences in heat pain and temporal summation threshold.

This study proposes the suggested amount of clothing (SAC) and examines the preferred amount of clothing (PAC) for thermal comfort in mild cold conditions. Six male and nine female college students were systematically exposed to mild cold conditions by reducing the amount of clothing (Step I, 1.2clo ${\rightarrow}$ Step II, 1.0clo ${\rightarrow}$ Step III, 0.8clo ${\rightarrow}$ Step IV, 0.7clo). The subjects were then asked to adjust the amount of clothing to attain overall thermal comfort until they maintained thermal comfort for 10 minutes without changing the amount of clothing (Step V). The experiment was carried out in a climatic chamber at $19.5^{\circ}C$, 50%R.H. Body composition was measured and individual cold climate adaptability was surveyed before starting the experiment. Rectal temperature ($T^{re}$), skin temperature ($T_{sk}$), and oxygen consumption ($\dot{V}O_2$) were measured and the overall thermal sensation was voted in each step. PAC was obtained from the garments weight selected by each subject in Step V. SAC was proposed based on the change of oxygen consumption (${\Delta}\dot{V}O_2$). As a result, males showed higher $\bar{T}_{sk}$ and greater $O_2$ than females (p<.01). SAC obtained from $\dot{V}O_2$ were 652.0 (SE 3.9) g/$m^2$ for males and 766.0 (SE 2.5) g/$m^2$ for females and it was significantly different between groups (p<.01). PAC of males and females were 1.6 and 1.5 times heavier than SAC. In conclusion, females were more sensitive to the cold stress and recommended larger amount of clothing than males.

In this study, the food intake, feces and urine of 16 primary school age boys and girls were collected and intake and excretion of sodium and calcium were measured. The boys and girls were 8-12 years old and measurement continued for four weeks during which they maintained their normal living pattern and body weight. Each boy's and girl's daily intake and excretion of sodium and calcium were measured and apparent digestibility and balance were also studied. The results were as follows. 1) Mean daily intake of sodium was 8.52$\pm$0.38g for the boys and 7.31$\pm$0.44g for the girls. The mean value in males was significantly higher than that in females(p<0.05). Mean daily in take of calcium was 411.0$\pm$16.0mg for the boys and 356.5$\pm$15.4mg for the girls. The mean value in males was significantly higher than that in females(p<0.01). 2) Mean daily fecal loss and apparent digestibility of sodium was 0.32$\pm$0.04g and 96% for the boys and 0.52$\pm$0.07g and 93% for the girls. The fecal loss mean value in males was significantly lower than that in females(p<0.05). Mean daily fecal loss and apparent digestibility of calcium was 299.8$\pm$8.3mg and 29% for the boys and 194.1$\pm$14.3mg and 46% for the girls. The fecal loss mean value in males was significantly higer than that in females(p<0.01). 3) Mean daily urinary loss of sodium was 6.55$\pm$0.50g and showed the positive balance of 1.65g for the boys and 5.67$\pm$0.20g and showed the positive balance of 1.12g for the girls. The urinary loss mean values of the two groups were not significantly different. Mean daily urinary loss of calcium was 42.8$\pm$5.1mg and showed the positive balance of 79.4mg for the boys and 25.0$\pm$1.64mg and showed the positive balance of 137.4mg for the girls. The urinary loss mean value in males was significantly higer than that in females(p<0.01).

The purpose of this study is to compare the relative risk of metabolic syndrome (MS) in middle aged adults with different body weights. 155 subjects living in urban Beijing were recruited from 24 neighborhood committees of urban Beijing. They were divided into normal weight, overweight and obese groups according to their BMIs. The general information of the subjects was collected using an interview-administered questionnaire. Standard procedure was followed to measure subject's weight, height and waist. Biochemical parameters (total cholesterol (TC), low- and high­density lipoprotein cholesterol (LDL-C ; HDL-C), triglyceride (TG), and fasting glucose) and blood pressure were also determined. The results indicated that the systolic and diastolic blood pressure, HDL-C of obese group was lower than that of the normal weight group. Fasting glucose of obese males was significantly higher than that of normal weight males. No significant difference of fasting glucose was found among female groups. No significant difference of TG was found among male groups, while TG of overweight and obese females was both significantly higher than normal weight females. There was no significant difference of TC and LDL-C among normal weight, overweight and obese groups in both males and females. The MS rate of obese males was significantly higher than the normal weight and overweight males, as was the female. The relative risk of MS in obese group was about 11 times higher (OR=11.249, $95\%CI$ = 3.812 - 33.191) than the normal weight group after adjusting for age, gender, smoking, drinking, family economic level and education status. It is concluded that obesity contributed to lower HDL-C, hypertriglyceride, hypertension and MS after controlling the effects of age, gender, socioeconomic status, alcohol drinking and smoking. Obese individuals have a higher risk of having MS than their normal weight counterparts.

The purpose of the study is to examine gender differences in health behaviors and the related factors for the urban elderly population. This study utilized the data from the Suwon city health survey of the elderly in 2001. The data consisted of a random sample of 979 (388 males, 591 females) elderly people aged over 65. The results of the study were as follows. First, the elderly people's health behaviors were different by gender. Concerning health risk-taking behavior, the frequencies of smoking and drinking were higher in males than in females. In terms of health promotive behavior, the regular exercise rate was higher in males than in females. Second, there were different factors that influenced health behaviors by gender. The factors that influenced the health risk-taking behaviors were health status factors for male, and socioeconomic factors for female. The factors that significantly influenced the health promotive behaviors were social supports networks for both gender. Therefore, program priorities need to be modulated in accordance with these gender differences in health behaviors. Moreover, different program strategies are needed that reflect the gender differences in health behavior determinants.

This study aims to determine adolescents' emotional response and preferences for varying interior designs of learning spaces available at community facilities in apartment across Seoul. In particular, the subjects have been fragmented by gender and age for comparative analysis of emotional responses across different demographics of adolescents. A survey on the preferred designs of learning spaces in community facilities revealed that 'elegant,' 'cheerful,' and 'temperate' are the three main emotional words selected for image tool development. Emotional assessment verified the validity of these terms. Between the two genders, adolescent males preferred 'temperate' images more while adolescent females preferred 'cheerful.' In terms of the design of learning space, adolescent females deemed the interior atmosphere and area space to be the most important factors, while adolescent males pointed to the color of furniture and lighting to be the most important. Such results imply that there is a clear difference of emotional response between adolescent males and females. The results also imply that different atmospheres and design priorities must be considered when designing gender-specific spaces.

This study was performed to measure the various dimensions of the hand for Korean adults. Three hundred and eighteen males and two hundred and sixty females, age ranged 18 to 60, participated in this study. Thirty-five dimensions were selected to measure. Subjects were divided into three age groups, 18 to 29, 30 to 39, and 40 to 60, for each sex. The data were analyzed to see the differences between the age groups and sex by using SAS program. The results showed that the measurements related to breadth and thickness tended to increase as the age increased. Wrist breadth, index finger breadth(distal), index finger breadth(proximal), thumb breadth, and index finger thickness(proximal) increased as the age increased for both males and females (p<0.05). However, the measurements related to length tended to increase as the age decreased. The relationship between the parts that are length related showed high correlation. Hand length showed high correlation with palm length, middle finger length and index finger length. Males' were significantly greater than females' in every dimension (p<0.05). Also, the results of this study were compared with the data of Japanese and U.S. army. The results of this study can be used to design the hand related products.

This study was undertaken to investigate the relationship between body mass index and the food habits of college students. For this purpose, 1030 students of Seoul National University were asked to fill out the questionnaires for the food habit and weight control. Actual weights were also measured, on the spot. The results obtained were as follows. 1. Average height and weight were 173.15 cm, 63.83 kg for male, and 160.52 cm, 52.73 kg for females. The prevalence of underweight, normal and overweight was 32.3, 61.7, 5.5%, respectively. 2. Food habit scores of obese females were lower than normal or underweight females. Male subjects did not show significantly different scores among three groups. 3. Female obese subjects have lower scores than the other groups on the balanced intake of five basic food groups and on the regular meal intakes. Male obese subjects have cholesterol-rich food and animal fat more frequently than normal and underweight males. Male underweight subjects have lower food habit scores on the balanced intake of five basic food groups. 4. Males want to gain weight slightly and females want to lose 4.65 kg weight. All females want to lose weights. Obese males and females want to lose 10 kg weights.
