In this research, I classified adult women's back types through anthropometric measurement and photographic measurement to present a judging individual body size according to the type. Also, Ⅰ calculated regression fomula by types and presented the basic bodice pattern. The results were as follows: 1. The result of factor analysis indicated that 5 factors were extracted and those factors comprised 75.89% of total variance. 2. According to the cluster analysis, Ⅰclassified the back types into 6 types. Type 1 was passive posture in the upper and the lower parts of the back. Type 2 was active posture in the upper and the lower parts of the back. Type 3 had the lowest protrusion of the back. Type 4 had the upper part of the back which is mostly bent downward. Type 5 was the most suitable shape. Type 6 had the lower part of the back which was turned over the most. 3. Ⅰconducted a discriminant analysis to judge the body types of individuals. 4. For the calculation of measurements necessary for the basic bodice pattern, Ⅰpresented regression formulas by each type. 5. By conducting the wearing experiments, Ⅰsuccessfully made the final basic bodice patterns by types. As a result of comparative experiments between the basic bodice patterns and comparison bodice pattern, the suitability of basic bodice patterns were more highly assessed.

The purpose of this study is to classify the types of men's back and chest through the criteria which represent the characteristic of men's back and chest. We have the following conclusions based on our sample size of 291 men's back and chest. The result of factor analysis concerned with men's back indicates that six factors are extracted and they are consist of 80.6% of total variance. We divide the shape of back into three categories: bent, protrusion of the scapula, and breadth. Each category is divided into subcategories. According to the frequency based on our data entries of 291 men's back, we introduce five new types of men's back. 83.8% of examined men's back belong to one of these five types: (i) 15.5% of protrudent and lordotic type; (ii) 6.5% of flat and lordotic type; (iii) 22.7% of protrudent and normal type; (iv) 34.4% of flat and normal type; (v) 4.8% of flat and bent type. The result of factor analysis related to with men's chest shows that six factors are extracted and they are consist of 76.0% of total variance. We divide the shape of chest into three categories: thickness, breadth, and protrusion of the breast. Each category is divided into subcategories. According to the frequency based on our data entries of 291 men's chest, we introduce four new types of men's chest. 65.0% of examined men's chest belong to one of these four types: (i) 7.2% of full and well-developed type; (ii) 24.1% of full and developed type; (iii) 25.8% of flat and developed type; (iv) 7.9% of flat and under-developed type. In order to consider the shape of the upper body as a whole, the back and the chest types should be corresponded.

Three kinds of tight skirts, slim type, straight type, and semi-tight type were investigated to obtain necessary information about the size of the back slit. Fourteen college students put on these experimental clothes and walked on the flat floor, going up and down the stairs. The dimensions of the back slit were measured by width and length. The stride length was taken from the record of footprints of walking. The correlation between the body measurement, stride length and the size of the back slit was studied. As a result of this experiment, the findings are as follows: 1. The size of the back slits differed from each skirt type at the level of p<0.001. In the case of walking on the floor, the average dimension of the back slit was 14.0 cm long 5.0 cm wide for the slim type,9.5 cm long 2.8 cm wide for the straight type and 2.1 cm long 0.5 cm wide for the semi-tight type. 2. In the case of walking on the stairways, the average dimension of the back slit was 16.0 cm long 5.8 cm wide for the slim type, 12.4 cm long 3.9 cm wide for the straight type and 3.1 cm long 1.1 cm wide for the semi-tight type. 3. The correlation between the height (stature, waist height, knee height) and the size of back slit was 0.3 to 0.6. The correlation between the girth (waist, hip) and the size of back slit was 0.3 to -0.5. 4. The correlation between the stride length and the size of back slit was 0.76 for the slim skirt, 0.56 for the straight skirt, 0.28 for the semitight skirt.

The purpose of this study was to attempt new starting motion and supply present starting motion in the 500M short track speed skating according to the center of gravity position. The center of gravity position ratio was divided starting motion into five(type A : front 80%-back 20%, type B front 70%-back 30%, type C : front 50%-back 50%, type D : front 30%-back 70%, type E : front 20%-back 80%). The three dimension motion analysis with DLT(direct linear transformation) method was executed using two video cameras. The following conclusion was that It was appear that reaction and execution time in starting motion was the most short in type B. It was characteristic that step of skaters was shorten and center of gravity position ratio was not effect to change of the step in each event. It was appear that the displacement of type D and type E were longer than that type A and type B during the starting motion. It was appear that skill types of center of gravity position ratio to the front were lower than that to the back and contract a posture. Observing the above, it was conclusion that skill type B of center of gravity position ratio to the tent was more effect than that to the back. But it is important that these skill type was most used to the competition and estimate the result.

Cooling clothes especially cooling vest are being considered for as an efficient way to reduce heat strain under hot environment. But wearing ice gel or ice-based cooling vest caused discomfort to subjects due to the weight of vest. Therefore, this study was executed to find efficient cooling parts and to reduce vest weight by cooling only these parts. Two male subjects were exposed to heat(40$^{\circ}C$, 30%RH) with A type(breast+back+abdomen+waist), B type(breast+back+waist), C type(breast+back+abdomen) and D type(breast+back) cooling vest that distinguished with cooling part. The results were as follows; When subjects were C type and D type vest, sweat volume was less and skin temperature was low. Heart rate and rectal temperature were low in B type and D type. These results suggest that excessive cooling of breast and abdomen may exert a bad influence to health and cooling of back is desirable.

In this study, the photographic and anthropometric measurements of men in the 20's were made. and pattern making professionals visually evaluated their side photos to classify lateral views. These data were analyzed by being compared with existing research results to select objective standards, and body types were classified according to the selected standard. In addition, body features were defined according to lateral views based on measurement items and indices, and standard lines and determining factors for visual evaluation which determines lateral views were revealed. Back length - front length size smaller than 1.5cm was named as the lean-back type, 1.5∼3.9cm was named as the straight type. and that larger than 3.9cm was named as the bend-forward type. In the straight type, the bisection point of waist depth was located at a similar place to tragion level vertical line. In the lean-back type, the point was at the front of tragion level vertical line. In the bend-forward type, the point was at the back of tragion level vertical line.

The purpose of this study was to classify body types of 800 female junior and high school students based on factor analysis, cluster analysis, and correspondence analysis of 15 photometric measurements of the subjects' lateral body lines. The results are as follows: The skeleton structure, which was represented the back bending by the photometric measurement, was already formed at age of 12 or 13, while the cervical skeleton, the size and inclination of the shoulder, and the degree of the lateral inclination of the upper body and the buttocks continued to grow by the age of 16. A factor analysis of the photometric measurement resulted in the sampling which determined the degree of the back bending, front-bust angle, and lateral view as well as the sampling whose factor represented the cervical inclination. A cluster analysis of the photometric measurement resulted in the four types of classification: Type 1, the straight type comprising 13.3% of the whole population; Type 2, the bent-forward type comprising 39.5%; Type 3, the lean-back type comprising 27.4%; and Type 4, the swayback type comprising 19.1%. Accordingly, the bent-forward type was found to be the dominant type among the four lateral body types.
