  • The use of relaxing cosmetic products is more and more widespread on the self care market, since stress is considered as a major cause of discomfort in modem life. Cortisol, the stress hormone, helps the human body to regulate itself by acting on carbonhydrate, proteins and fat metabolisms. IgA are immune molecules involved in the stress response of the human body. The less the human body is stressed, the more the salivary IgA rate increases. Salivary cortisol and IgA have the advantage of being easily assessed with non invasive methods. Finally, conductance is the measurement of the modification in the electrical resistance of the skin. By this means, the measurement of the conductance enable the assessment of somebody's stress.(omitted)

  • The purpose of this study is to examine the increments of body measurements of the teenage boys between the ages of 13 and 18 and provide a fundamental data for apparel manufacturers in order for them to make clothing that reflect the appropriate body characteristics of the teenage boys. The total of 1587 male subjects between the ages of 13 and 18, from the 5th Anthropometric survey of Korea (Size Korea) data, were used for this study. The changes in the body dimensions were analyzed with anthropometric measurements and anthropometric index mesurements. First, anthropometric measurement results show that most of the height related measurements increased in accordance with age, and that the boys between the ages of 13 and 15 experience dramatic growth. Standard deviation is the largest between the age of thirteen and fourteen which indicates that in these ages there is a wide difference in a growth rate Second, anthropometric index measurement results show that in accordance with age, bust, waist and hip depth/width rate decreased; however, waist and hip depth/width rate increased at the age of 18. In accordance with age, upper body length rate increased, whereas lower body length rate decreased. Bust circumference, armhole length, and upperarm circumference rate increased gradually, whereas waist circumference decreased.

  • Body measurement was held for the subjects of Chinese adult males in their 20s through 40s residing in the Ningbo area of Zhejiang Province in order to provide body type information and raise the fit of clothing products for the advancement into the Chinese market. The following sums up the analysis of body types based on body measurement: 1. Seven factors to compose body types were produced from the analysis of males in their 20s, explaining 76.07% of variables and representing 3 types according to cluster analysis. Type 1 was H-b and appeared as much as 32.14%. Type 2, semi X-d, was 40.81%, while Type 3, A-i, had 27.04%. 2. Eight body type composing factors were extracted from the analysis of men in their 30s and 40s. The factors explained 76.77% of all the variables and represented 4 types according to cluster analysis. Type 1, H-d, had the appearance rate of 18.47%; Type 2, H-b, 40.84%; Type 3, Y-i, 27.71%; and Type 4, semi X-s, 11.95%.

  • The purposes of this investigation were to determine the validity of various methods (available anthropometric equations and near-infrared light interactance) for estimating body fat and to develop multiple regression equations for the prediction of body fat. Thirty-eight healthy males(age: 20.87$\pm$7.17 yrs) and 12 females(19.58$\pm$2.19 yrs) underwent hydrostatic weighing to determine body fat. Anthropometric measurements were taken of height, weight, nin skinfolds and thirteen circumferences. The results obtained are summarized as follows: 1) Relative body fat determined by underwater weighing was 12.08$\pm$5.21% for the males and 17.97$\pm$5.75% for the females. 2) Circumference and skin fold that had the highest correlation with the body fat were waist girth in males and females(r=0.60, r=0.96, respectively), and subscapular in males(r=0.68) and triceps in females(r=0.96). 3) Corss-validation of 18 selected equations on males revealed total errors ranging from 3.76% to 5.06%. Among these equations, M3(Pollock et al.) demonstrated the least total error. Total error of estimation by near-infrared(NIR) was less than that of available anthropometric measurement equations. The results of the cross-validation of 12 equations on females revealed that F3(Sloan et al.) was clearly superior in accuracy of prediction. 4) Correlational analyses showed that estimation of body fat by NIR measurement seemed to be more closely associated with body fat determined by underwater weighing in women than men, in older subjects than younger ones, and in fatter subjects than leaner ones.

  • Bicycle fittings have been used to ride bicycles comfortably while minimizing non-traumatic injuries. To analyze the cause of non-traumatic injuries, it is necessary to measure the body weight distribution in various biking positions. In this study, a weight distribution measurement system was implemented by installing five weighable devices on the saddle, both pedals, and both handle grips of a bicycle. To measure the body weight applied through the saddle, the structure of a commercial seat post was modified and a load cell was installed inside. Weighable pedals and handle grips were designed using a 3D modeling program and fabricated by employing a 3D printer. The body weight distribution for ten bicycle riders was measured when the two pedals were aligned horizontally and vertically. Experimental results showed that the body weight distribution varied significantly depending on human body shape, even after the bicycle fitting was completed. The difference between the body weight measured by the proposed system and a commercial scale was less than 3 %.

  • This Paper addresses what amount of whole-body vibration is exposed to Korean pilots of UH60 helicopters during their mission flight. To measure the expose4 whole-body vibration, the 12-axis whole-body vibration measurement system was used. It enables the direct measurement of whole-body vibration exposed from the body contact area consisting of the feet, hip and back. The measured 12-axis vibration signals were used to evaluate the vibration comfort level experienced by the pilots of UH60 helicopters. The evaluated vibration comfort level is found to be closeto 0.74-0.79m/s, which is equivalent to the semantic scale of 'fairly uncomfortable'. To assess the health effects of whole-body vibration exposed to Korean pilots of UH60 helicopters during their mission flight, the rms-based and VDV(vibration dose value)-based evaluation schemes, recommended by ISO 2631-1:1977, were exploited in this work. The evaluated results indicate that Korean pilots cannot avoid the fatigue-decreased proficiency limit after two-hour continuous flight. The whole-body vibration level exposed from the UH60 helicopters during continuous 10-hours mission flight is found to reach to the vibration exposure limit.

  • The purpose of this study was to investigate the changes in body temperature of canine via their hair lengths before and after grooming. A total of 120 companion canines were used in this study for a total of 6 weeks, and 20 dogs each week consisted of both 10 poodles and 10 malteses (five females and males). For accurate temperature measurement, the anal depth was measured at approximately 1.5 cm. Temperature before and after grooming was measured at 10 am and after more than three hours, respectively. There was statistical significance (p<0.05) in body temperature changes for male poodles at 1, 2, and 3 weeks and for female poodles at 1, 3, 4, and 5 weeks, and the total period showed a statistical difference for both male and female poodles (p<0.05). In addition, male and female malteses had an effect (p<0.05) on changes in body temperature at 1 and 6 weeks and only at 4 weeks, respectively. For total period, there was a statistical difference in male and female poodles (p<0.05). Moreover, when the temperature changes of females were compared, there was no remarkable difference. In conclusion, the body temperatures of both male and female dogs according to the length of their hair were lower after grooming than before grooming. The measurement of body temperature three hours after grooming, which could reduce stress or other factors, is judged to be able to help customers who are worried about clipping.

  • The growth of the middle school girls show big difference among the individuals and the development of each area of the body is not uniformed but diverse which could be understood as the period that the problems on the fit of the clothes occur extensively. Therefore, in this study, the somatotype of the middle school girls are intended to be categorized for the highly applicable clothes design. For this, the 3 middle schools in Jeonju were selected for anthropometric measurement of 324 middle schools. The items of measurement are related to the somatotype of middle school girls, clothes design which is consisted of total of 50 items. For the basic data of clothes was judged that the classification of somatotype related to the tops and bottoms would be rational; hence, it is classified into the upper part and lower part of the body to extract the body shape consistent factor. As a result of analyzing the factors, the upper body consistent was extracted as the 4 items: upper body circumference, upper body length, breast growth and arm length. It was displayed as 75.26% explicability. The lower body consistent factors are extracted as lower body height, lower body circumference, hip length, and rear shape with 78.62% explicability. To classify the somatotype of upper body and lower body, each factor score is made into the independent viable for group analysis. As a result, the upper body was classified into the 'upper body with small breast and long' and 'upper body with big breast'. The lower body was categorized as 'lower body with long hip length' and 'standard lower body'.

  • A 3D body scan measurement (SM) is used as an alternative to physical measurements (PM) as the information for designing industrial products. This study compared the mean difference (MD) between SM and PM by gender and analyzed the causes of the difference. The data used in this study were the scan measurements and physical measurements of adults aged twenty to seventy years old of the fifth Size Korea survey. The results of this study are as follows: 1. The comparison of MD between men and women for all subjects: The measurement of the significant differences between men and women were height, neck base girth, chest girth, under-bust girth, waist girth, armscye girth, back length, and foot length. The causes of difference are the difference of body shape. 2. The comparison of MD between men and women by BMI groups: Many measurements had significant differences between men and women at normal weight and overweight but underweight. Some measurements had significant differences only at a specific BMI group because the body shape difference between men and women is revealed clearly in the group. The comparison of MD between men and women by age groups: The measurements that show significant difference at more than four age groups were neck girth, chest girth, under-bust girth, waist girth, armscye girth, and foot length. The height and abdomen girth had a significant difference in the age range of 20's and 30's. There were measurements that increase MD with an increase in age; under-bust girth and lateral shoulder length for women and lateral shoulder length for men. This comparison of MD between men and women provide the correct guidelines for the use of SM.

  • The purpose of this study was to suggest torso patterns that fit the three main body shapes of elderly obese women. To reduce time, costs, and also the trial and error needed to make patterns, the CLO program for 3D test wear was employed. Three virtual models for aged obese women were use, with the YUKA system used to produce torso patterns. 3D simulation of test wear and corrections was done to design optimal torso patterns. The results were as follows: First, for the three models of obese women's body shapes as realized by CLO 3D, Type 1 is lower-body obesity shapes, Type 2 is abdominal obesity shapes, and Type 3 is whole-body obesity shapes. Second, to design the study patterns, actual measurement values, back waist length and waist to hip length, were used. The armhole depth (B/4-1.5), front interscye (B/6+2.3), front neck width (B/12-0.5), front neck depth (B/12+0.5), front waist measurement (W/4+ 1.5+D), front hip measurement (H/4+2+0.5), and back hip measurement (H/4+3-0.5) were calculated using formulas. Third, according to the results of test-wearing the study patterns, reduced front neck width and depth improved the neck fit and reduced armhole depth bettered loose or plunging armhole girth and also reduced the sagging of bust c.. Also, tight sidesfrom aprotruded waist and abdomen improved with the increase of surpluses in the back waist and also back and front hip c. The exterior was enhanced by displacement of back and front darts, which distributed surpluses better.
