  • The optical method Digital Speckle Correlation Measurement (DSCM) has been extensively applied due its capability to measure the entire displacement field over a body surface. A formula of displacement measurement errors by the gradient-based DSCM method was derived. The errors were found to explicitly relate to the image grayscale errors consisting of sub-pixel interpolation algorithm errors, image noise, and subset deformation mismatch at each point of the subset. A power-law dependence of the standard deviation of displacement measurement errors on the subset size was established when the subset deformation was rigid body translation and random image noise was dominant and it was confirmed by both the numerical and experimental results. In a gradient-based algorithm the basic assumption is rigid body translation of the interrogated subsets, however, this is in contradiction to the real circumstances where strains exist. Numerical and experimental results also indicated that, subset shape function mismatch was dominant when the order of the assumed subset shape function was lower than that of the actual subset deformation field and the power-law dependence clearly broke down. The power-law relationship further leads to a simple criterion for choosing a suitable subset size, image quality, sub-pixel algorithm, and subset shape function for DSCM.

  • Objectives : The purpose of this study was to establish an accurate and effective method of locating acupoints of the forearm by studying bone proportional measurement. Methods : A total of 60 volunteers, 30 men and 30 women, participated in this study. 7 parts of the body were measured by a soft ruler or digital vernier calipers. The cun of the upper limb was calculated and analyzed. And the results were compared with the standard cun. Results : The bone proportional cun of the forearm based on height and femur was close to 11. It was different from the standard 12.5, 12 or 10. The cun of the forearm by thumb or finger width measurement was different from the standard too. Conclusions : We suggest that locating acupoints of the forearm needs to be done based on 11 cun. The confusion on locating acupoints of the forearm will be reduced by reflecting the result of the actual measurement.

  • 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.

  • By cluster sampling measurements, passing months of pregnancy according to changes of pregnant women body forms. On the basis of the above mentioned data, sizes of pregnant women clothes were decided. The results are as follows. 1. By cluster sampling measurements, sixty-nine items of apparel were obtained during the three different periods of pregnancy. They included the mean and standard deviation of body form measurement and the minimum and maximum values (Chart 3-4). The results of these surveys made it possible to notice the changes of pregnant womens' physical characteristics, i. e., the increased physical proportions: frontal waist area, umbilicus width, abdominal girth, crotch length, the length of the nipple, and body weight and the decreased proportions: omphalos height, perineum dimension. There was little change in the rear parts of the body. 2. The analized results of principle factors for body form measurements by cluster measurements produced seven major factors for which the proper values were over 1.0. They were: form factor, pregnancy factor, posture factor, breast formation factor, rear body formation factor, and nipple to nipple breadth. 3. In deciding garment sizes of pregnant women, four different sizes were established; small, medium, large, and extra-large according to the third, fifth, eighth, and tenth month of pregnancy. The measurement value of each item was produced by estimate.

  • In this study, we attempted to make an original pattern of clothing for an abnormal type of figure, especially for the type of kyphosis. We measured the curvature of the spine of a woman with kyphosis with a Martin measuring instrument and a silhouetter in the following ways. First, we counted the rate of shrinkage of the standard lines drawn on the surface of the body according as the body moved. Secondly, placing the front and back darts, the front and back shoulder darts and the side darts according to“Munhwa”pattern, we made cubic cuttings of four moving postures as well as the standing one. Thirdly, we superposed the developed patterns of the standing and the moving postures, measuring the position change and the amount of the chaange of the darts, and compared them. The results are as follows: 1) In the developed pattern of a cubic cutting of the basic pattern and the standing posture, the neckhole became larger than that of the basic pattern, and the waist line was lowered than that of the basic pattern because the center back line was shortened due to the curved backbone. 2) As for the change of the standard line according to the movement, we found that the waist line, the center front line, the center back line, the bust width line, the upper back width line and the back width line became longer. Special consideration must be given to the function of the clothing for an abnormal type of figure. 3) The difference of the measurements between the cubic cutting and the body measurement regardless of the body movement is due to a gap by an acute angle at the jutted place between the developed pattern and the body surface. We found that the body measurement of the upper back width line, the back width line and the bust line became larger. Consequently, in making an original clothing pattern, it is desirable that we must not place the front and the back waist darts at the jutted place on the back from the functional and the aesthetic viewpoint of clothing. It is also desirable that we must widen the neckhole because the shoulder angle is close to a straight line due to a jut of the upper back width line.

  • 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'.

  • The purpose of the study was to offer basic documents to the textile fashion industry by investigating changes of figures followed by various factors as each other social and cultural environment regardless of the same race. The study conducted a questionnaire survey of Korean women and Korean women in Japan to twenties, forties and sixties. The study enforced measurement from February, 2006 to March, 2006 and from July, 2006 to August, 2006 with R. Martin's Measurement Method of Anthropometry in total 49 measurement items. Also, the study treated statistics of the documents with SPSS WIN 10.0 program. As the result which studied comparison of figures with basic statistics, t-test and more, the study got the following conclusion. Most of Korean women and Korean women residing in Japan have big individual differences in obesity, especially width, thickness, and girth of waist showed the largest variation proving considerable individual difference in waist. In a body measurement comparison, twenties, forties, and sixties of Korean women residing in Japan are higher in heights compare to Korean women, while Korean women have wider and thicker waists than Korean women residing in Japan. In a body difference comparison, categories that showed significant differences are 40's>20's>60's in order and twenties and sixties showed only small difference. In conclusion, Korean women have longer, wider, thicker and smaller waist than Korean woman residing in Japan. When divided by age groups, forties and sixties Korean women are longer in waist, shorter in heights, fatter in weights. Twenties have long waist similar to forties and sixties, but had no significant difference in heights and weights.

  • This paper introduces a vision-based automatic system (VAMS) for non-contact measurement of morphometric characteristics of flatfish, such as total length (TL), body width (BW), height (H), and weight (W). The H and W are simply measured by a laser displacement and a load cell, respectively. The TL and BW are measured by a proposed morphological image processing algorithm. The proposed algorithm cans measurement, when the tail of flatfish is deformed, and when it is randomly oriented. In the experiment, the average and maximum measurement errors were recorded, and standard deviations and coefficients of variation (CVs) for the measurements were calculated. From those results, when flatfish the TL measurements had an average of 266.844 mm, a standard deviation of 0.351 mm, a CV of 0.131%, and a maximum error of 0.87 mm with straightened flatfish ($TL_A$ : 267 mm, $BW_A$ : 141 mm), and when flatfish of different sizes were measured, the errors in the TL and BW measurements were both about 0.2 %. Using a single conveyor, the VAMS can process up to 900 fishes per hour. Moreover, it can measure morphometric characteristics of flatfish with a TL of up to 500 mm.

  • This study is to classify the somatotypes of middle-aged women by many critera and figure out he characteristics of each somatotypes. The subjects are 614 middle-aged women between 35 and 59 years old and the research is based on anthropometric and photometric measurement by photographing their body parts. The results are as follows; 1. The result of factor analysis indicated that 11 factors were extracted through factor analysis and orthogonal rotation by the method of varimax and those factors comprised 85.71 percent of total variance. 2. As the result of cluster analysis the group of the middle-aged women is classified as 6 types. Type 1 is short, fat, H type in front and lean-back type on the side. Type 2 is standard in height and weight. Type 3 is standard height, fat, long upper body, bend-forward type and protrude of the hip on the side. Type 4 is tall, thin, short upper body, having clearly protrude of the back and hip and lean-back type on the side. Type 5 is neither short nor tall, slim, X type in front and I type on the side. Type 6 is tall, thin and B type on the side. 3. As the result of observing the mutual corresponding relation between these 6 groups and age/Rohrers Index, the somatotype of the middle-aged women is divided at the age of 45. Accordingly when it comes to progress the study of the middle-aged women in the future, we will have to observe the characteristics for dividing the first half and the second half of age of 45.
