This study researches the preferred ease of torso sloper according to body sizes and drop. For this, the eases of main body parts such as chest circumference, waist circumference, hip circumference, biacromion length, and waist back length were analysed; in addition, the drop differences of body and pattern were explored to find out characteristics of silhouette changes. The subjects were 55 women in their early 20s (aged from 20 to 24) and individual torso block made with muslin was corrected 1-3 times by a personal fitting. There were 3 meaningful results. First, the preferred ease were individually various; however, the eases of all torso blocks should be same at the pattern making step. Second, the eases were also significantly different among body size groups and the bigger group preferred less ease at the biacromion length, waist back length, armhole-depth, chest circumference, and waist circumference. Third, the eases of chest circumference and hip circumference were significantly changed among drop groups. To change their body drop, H-shape drop adopted less ease at chest circumference and more ease at hip circumference; however, A-shape drop adopted more ease at chest circumference and less ease at hip circumference.

Objective: The purpose of this research was to aid creating an effective sizing system for the vacation wear intended for Jeju's medical tourists, specifically females from the major countries including the USA, Japan, and Korea. Background: Medical tourism makes the gains of every year 40,000,000,000 dollar, every year 30% it is increasing. Thus the Jeju-do is propelling medical tourism. The body size each country is different. Consequently must set the body size standard for the women. Method: (1) It observed the body size of the Korean women of 2004 years and 2010 years. (2) It analyzed the body size of the women of the USA, China, Japan and Korea. (3) It set the sizing system of the women of the USA(ASTM), China (GB), Japan(JIS) and Korea(KS). Results: Korean adult females' height in 2010 has increased from 2004. The Waist Back Length, Waist Front Length, Arm Length etc has also increased along with the Height. The upper body has become slimmer at the same time; the Chest Circumference, Bust Circumference, and Underbust Circumference have decreased. The lower body on the other hand has become bigger: the Waist Circumference and Hip Circumference have increased. The BMI has decreased by 0.4 from 2004 - the Height has increased while Weight has decreased. The Chest Circumference and Under Bust Circumference of Korean women across all age groups have increased at a proportional rate to other parts of body; however, the rate of increase in Chest Circumference was far greater. American females(Caucasians) had the greatest ratio of waist to bust (Waist Circumference/Chest Circumference), smallest ratio of Neck Base Circumference to Bust Circumference (neck/bust). Korean females had smallest ratio of Waist Circumference to Underbust Circumference(waist/bust). As for the drop of Chest Circumference and Waist Circumference, American females had the highest and Koreans had the lowest. As for the drop of Hip Circumference and Chest Circumference, Japanese had the highest and Americans had the lowest, but Japanese women at the same time showed the A line body shapes. As for difference of Chest Circumference and Underbust Circumference, American females had the biggest(13.73) followed by Korean(11.1), Japanese(10.9) and Chinese(10.5). Conclusion: The women of the USA, China, Japan and Korea body size is different. Especially the value of the Bust Circumference - the Underbust Circumference is different. Thus, it set the sizing system(Table 8).

Purpose: Circumference of the chest and waist can be one of clinical indicator to reflect respiratory function in children with cerebral palsy. In this study, we compared to differences in the chest/waist circumference and maximal phonation time between children with spastic diplegia and hemiplegia. Methods: Seventeen children with spastic diplegic and hemiplegic cerebral palsy were recruited, who were matched to gender, age, height, weight, and body mass index for control of the known factors affected to respiratory function. The chest/waist circumference and were measured in each group, when children took a breath at rest and at maximal voluntary inspiration/expiration. Results: No significant differences were found in the chest and waist circumference and expansion between the two groups. However, only in the waist expansion, children with diplegic CP were significantly lower extensibility of lung, compared to the other group. In comparison of the maximal phonation time, a significant lower score was shown in children with spastic diplegic CP, compared to children with hemiplegic CP. Conclusion: Our results indicated that children with spastic diplegic CP had smaller chest wall and waist, compared to children with spastic hemiplegic CP. In addition, they showed a shorter time for sustaining phonation than spastic hemiplegic CP did. Therefore, spastic diplegic CP will be required for careful monitor regarding respiratory function in rehabilitation settings.

The purpose of this study is to provide basic data for the medical nutrition therapy of premature infants. The general characteristics, presence of metabolic disorders, hematological profile and feeding methods were compared between the premature infant group (<37 weeks, n=61) and the full-term infant group (37$\sim$42 weeks, n=165). Birth weight (p<0.0001), birth length (p<0.005), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores (p<0.0001) of the neonates were all statistically lower in the premature infant group. Jaundice cases (p<0.0001) were statistically higher in the premature infant group. White blood cell counts (WBC: p<0.005), mean corpuscular volume (MCV: p<0001), mean corpuscular hemoglobin (MCH: p<0.005), mean corpuscular hemoglobin concentration (MCHC: p<0.005), and mean platelet volume (MPV: p<0.05) were statistically lower in the premature infant group. The premature infant group were fed a higher rate of premature formula than breast milk and the full-term infant group were fed a high rate of human milk at a higher rate, showing differences in kinds of feeding methods (p<0.0001) between the two groups. An infant's birth weight showed a significantly positive correlation with the infant's birth length (p<0.0001), head circumference (p<0.0001), chest circumference (p<0.0001), and Apgar scores(p<0.0001). The birth length also showed a significantly positive correlation with both head circumference (p<0.05) and chest circumference (p<0.05). Head circumference showed a significantly positive correlation with chest circumference (p<0.0001) and Apgar scores (p<0.0001). Chest circumference showed a significantly positive correlation with Apgar scores (p<0.0001). In addition, the Apgar Score at of 1 minute after birth showed a significantly positive correlation with the Apgar score at of 5 minute after birth (p<0.0001).

This study was to research the characteristics of the somatotype of Korean farmers. 836 Korean farmers(Male: 361 persons, Female: 475 persons) volunteered for this study. They volunteered from 9 different area such as Kumi, Damyang, Iksan, Injae, Chungju, Choongju, Haman, Whasung, and Whasoon. The reusults were as follows: 1. The subcutaneous body fat thickness were decreased as they aged(p<.05). 2. The thicker the subcutaneous body fat thickness of Korean farmer, the wider the circumference size by the Korean famer's physical parts(p<.05-p<.001). 3. There were no significant differences in the circumference size such as upper arm, chest, bust, waist, umbilical waist, hip, and calf between Korean farmers and Korean standard size. 4. Korean women farmer showed significantly differences in the upper arm circumference(p<.01), the chest circumference(p<.01), the bust circumference(p<.01), the waist circumference(p<.01), the umbilical waist circumference(p<.01), and the calf circumference(p<.05) from Korean women standard by ages. Especially, Korean women farmer had thicker the umbilical waist circumference(the 40's: 103.2mm, the 50's 52.3mm, the 60's 22.3mm, over 70's 22.1mm) than Korean women standard. 5. The 40's women farmer had thicker the upper arm circumference, the chest circumference, the bust circumference, the waist circumference, the umbilical waist circumference, and the calf circumference than Korean women standard. The 70's women farmer had skinner circumferences except the umbilical waist circumference than Korean women standard. 6. Korean farmers showed the crooked back shape, the broad-knee length and also front-bending knee shape as they aged.

This study analyzes the body sizes of young boys in order to categorize a sizing system for middle and high school uniforms. The study was based on the $6^{th}$ National Anthropometric Survey (Size Korea 2010) data. The sample size consisted of 2,317 boys between the ages of 13 and 18 years. Most measurement items increased significantly relative to age and there was rapid growth between the ages of 13 and 14 years. The growth for the chest and hip was more than the waist. The drop value 1 (difference between chest circumference and waist circumference) and the drop value 2 (difference between hip circumference and waist circumference) increased remarkably from the age of 13 to the age of 15. Therefore, the waist size decreased and chest and hip became wider relative to the age increase. Middle school students had a smaller chest and hip circumference than high school students in the comparative body measurement results for middle school students (13-15 years) and high school students (16-18 years) of the same height group. The somatotype of high school students showed a long trunk length, broad chest and shoulder.

The purpose of this study was to establish the proper amount of eases according to the body type of men's bodice basic pattern. The 3 subjects in 30's men were selected for developing fitted pattern for each type. And the results of the wearing test for individual subject by distributing ease amount are as follows. The wearing test is administrated by a division of 12cm, 15m, and 18cm areas respectively after separating the fitted pattern for each type in a vertical and horizontal ways. There exists a significant difference in ease according to the measures of chest circumference of subjects. Also, it is shown that the more comfortable in function, the better visible in appearance as the ease gets proper. As to regions, the amount and ratio of ease chest circumference are increased in proportion to the size of the chest circumference. The scye depth is affected by the ease of chest circumference, while the ease of the interscye and the back breadth are lessened due to the effect of their appearances. And the side breadth is required as a buffer to complement the shortage of the interscye and the back breadth because the ease of either the interscye or the back breadth is partially transferred in motion.

Background: Patients with stroke have core muscle weakness and limited rib cage movement, resulting in restrictive lung disease. Objectives: To examine the comparison of effects of rib cage joint mobilization combined with diaphragmatic breathing exercise and diaphragmatic breathing exercise on the pulmonary function and chest circumference in patients with stroke. Design: A cluster randomized controlled trial. Methods: Twenty-four patients were randomly assigned to an experimental group (rib cage joint mobilization combined with diaphragmatic breathing exercise group) and control group (diaphragmatic breathing exercise group). Patients in the experimental group underwent rib cage joint mobilization for 15 min and diaphragmatic breathing exercise for 15 min. The control group underwent diaphragmatic breathing exercise for 30 min. Both groups underwent exercise thrice a week for 4 weeks. The pulmonary function and chest circumference were measured using the MicroLab spirometer and a tape measure, respectively. Results: After the intervention, the pulmonary function and chest circumference significantly improved in both groups. These improvements were significantly higher in the experimental group than those in the control group. Conclusion: Rib cage joint mobilization combined with diaphragmatic breathing exercise improves pulmonary function and chest circumference in patients with stroke.

The purpose of this study is to classify the upper body of women into several kinds of somatotypes, using the method of Surgical Tape and making their shells. The subjects are 53 females 30 to 39 years-old. Fifty-three anthropometric data are measured per shell of bodysurface; six somatotype factors are obtained through principal component analysis and orthogonal rotation by the method of Varimax, Somatotype of women's upper body is achieved by cluster analysis, using the standardized factor score as an independent variable and the FASTCLUS of SAS by Kmeans. The results are as follows: 1. The number of the factors which explain the somatotype is six and those factors comprise 76.12 percent of total variance. Factor 1: related to the size of shape in the front of upper body Factor S: related to the size of shape in the back of upper body Factor 3: related to the type of the upper chest over the chest circumference line Factor 4: related to the length of·the upper body Factor 5: related to the part of the neck Factor 6: related to the type of the lower chest under the chest circumference line 2. Cluster analysis results in classification of upper body into five clusters. Cluster L: the length is the largest and the circumference is small. The part of waist is the largest and widest among surface areas. Cluster 2: Slender body line from chest to waist is characteristic. The length is longer. The part of upper and lower chest is larger among surface areas. Cluster S: the circumference is the smallest and armhole is small. The length and surface area are small. Cluster 4: the circumference and armhole is the largest. The length is the smallest. Cluster 5: the circumference is average and the length is a little long. The body line(silhouette) from chest to waist is curved slightly.

The usage of basic bodice blocks at men's apparel companies is investigated and the domestic and international men's upper bodice blocks are compared to find directions of research on development of bodice basic blocks. The following conclusions are found in this study. 1. The survey shows that basic bodice blocks are not used at men's apparel companies although all the respondents have good knowledge on bodice basic blocks. They responded that basic bodice blocks for representative body figures of each age category or of each country would help comparative studies on domestic and international basic bodice blocks and development of exporting apparel products. Also, they expected the utilization of men's basic bodice blocks both as education materials and in studies of design, of body figures, and of basic blocks for industry. 2. The comparative study on men's bodice blocks shows that waist circumference, hip circumference, neck circumference, height, and shoulder length, in addition to the minimal essential size items such as chest circumference and center back length, are used in most basic bodice blocks. The size formulae of each basic block are compared to find how the sizes are determined. For center back length, either measured back length or a certain proportion of height is used. For front and back interscyes, chest circumference is used in most basic bodice blocks. Either measured size, or a certain proportion of height or chest circumference is used for back height. The averaged ease allowances of basic bodice blocks are 3.2 cm for chest circumference, 10.8 cm for waist circumference, 1.2 cm for front interscye, 0.1 cm for back interscye, 0.2cm for shoulder length, and 0 cm for center back length. However, body blocks for different types of clothes have different ease allowances. Shirt basic blocks have ease allowances of 6.1 cm for chest circumference, 13.7 cm for waist circumference, 1.4 cm for front interscye, 0.6 cm for back interscye, 1.2 cm for shoulder length, and 1.8 cm for center back length. On the other hand, jacket basic blocks have ease allowances of 8.8 cm for chest circumference, 16 cm for waist circumference, 1.1 cm for front interscye, 1.4 cm for back interscye, 1.1 cm for shoulder length, and 0.8 cm for center back length.
