The objectives of this study were 1) to investigate the clothing needs of physically han- dicapped children, 2) to present the basic data to make the slacks patterns which meet the specific needs of physically handicapped children under study. Questionnaires were administered to 38 mothers of handicapped children and the subjects for the wear test were five handicapped children using wheelchair. The fabrics used for slacks wear test were: muslin woven with cotton, stretchable jean woven and double jersey knitted with cotton and polyester fabrics. The results obtained from this study were as follows: 1) The majority of the handicapped children were wearing ready·made-garments and their mothers considered the fabric elasticity first. 2) The slacks wear test indicated that the slacks ease of 8 cm should be added above the natural waist line in the back for the wheelchair bound children. 3) In a sitting posture on the wheelchair, $3\~4$ cm should be cut below the natural waist line in the front but in a standing posture, $1\~2$ cm should be cut below the natural waist line in the front. 4) The double jersey (cotton/polyester) slacks was highly estimated of ease ana length of slacks in a sitting posture. The stretchable jean (cotton/spandex) slacks was estimated high of appearance but muslin slacks (cotton) was less estimated of ease and appearance of slacks.

This study was conducted to examine the relation between the clothing materials and the garment's ease under wearing condition. Wearing test of slacks in the same pattern which were made of 3 woven fabrics and 1 knitted fabric have teen carried out. Subjects were 5 female students. Some physical properties of these fabrics were investigated. The following results were obtained. 1, By analysis variance with the results of sensory test which was tested by paired com-parison method, it was obtained that the effect of materials on the garment's ease were significant at the $1\%$ level on every part of stacks and posture of subject. It indicates that there is a difference of materials from materials in garment's ease. 2. Significant at the $5\%$ level among the materials. Jersey and Jean were looser than the other two materials. Clothing materials have considerable effect on the garment's ease of slacks, therefore it was noticed that the ease of slacks must have considered the clothing materials. It is more necessary in working dress. 3. Elastic recovery of width was more contributive to garment's ease of slacks than any other physical properties.

Journal of the Korean Society of Clothing and Textiles Vol. 18, No. 3 (1994) p. 387∼394 In this study, the restriction of slacks (blue jean) versus box pleats skirt was investigated, from the view point of peripheral blood flow at the toe according to motion variation and E.M.G. analysis of leg muscles after walking on the flat or going up and down stairways. Besides, the pressure of slacks on the lower extrimity was measured statically and dynamically. The main results were summerized as follows; 1. The clothing pressure applied by slacks was; each one of thigh and lower leg was 18.2 g/ cm2 and 22.1 g/cm2 in upright, 63.4 g/cm2 and 26.6 g/cm2 in sitting on the chair, on both sides of thigh and lower leg 272.0 g/cm2 over in squatting. 2. When the motion starts from upright, the dynamic clothing pressure reach their peak before the motions end. When the motion ends and the body comes to a still condition, the clothing pressure grow lower and indicate a constant value. but when the body starts moving again to return to upright, the pressures once grow higher and go to zero value after reaching the peak. The pressure on the knee show much greater than those on the hip. This can be because these pressures depend on the degree of skin stretching motion and of its curvature. 3. The surface E.M.G. in leg muscles M. rectus femoris and M. gastrocnemius were recoreded. In the case of wearing slacks, two muscles were activated much more than wearing skirt. 4. The peripheral blood flow at the toe by wearing slacks was lower than wearing skirt. Also the case when squatting, the peripheral blood flow at the toe was low.

This study was conducted to examine the changes of the mechanical properties of the position in jean slacks during the wear, previously used for the wearing test, which were subjected to repeated tensile-shearing deformation using a simulated fatigue tester has been investigated and compared, by calculating both mechanical properties and hand value(HV) of these fabrics with KES-F system and the by obtaining the THV through these calculated properties. The results are as follows. 1. The fatigue phenomenon of mechanical properties was the LT, 2H B, 2HBS, MMD, SMD, RC values increased, elasticity values of tensile, bending and shearing properties, such as B, G and compression properties LC, WC were reduced. It was shown, then, that those fabrics lost their elasticity and became flexible and soft with the increase of fatigue. 2. The hand value and THV; except anterior knee from all part of KOSHI, NUMERI, FUKURAMI was decreased. 3. The fatigue phenomenon of hand value was different on the position of clothing; on the position of hip, rate of B, G smaller than other parts and KOSHI was decreased, on the part of anterior thigh was FUKURAMI was increased, on the anterior knee RC, NUMERI, THV was increased, on the posterior knee was 2HB, 2HG, 2HGS showed increasedgreater than any other part and on the hem of back, MMD was increased, but NUMERI was decreased. 4. The changing process of mechanical properties in the simulation testing by the fatigue tester has similar tendency to that of the wearing tester. It is concluded that this testing method is useful to predict the fatigue phenomena of fabrics caused by wearing.

The mechanical properties of jean slacks to the type of cutting lines in knee region and the bending time, after doing bending 0 times, 500 times, and 1500 times, the effects of whether or not cutting line, the fabric direction of the cutting area, and the number of cutting lines were investigated for tensile, shearing, compression, and mixing value of mechanical properties. The results are as follows: EM to bending times were larger in order of weft

This is the result of the comparison of the number of jeans, colors, images, opinions when it was purchased, shapes according to the gender of persons in jeans. According to the gender, male students had 1.64 jeans(46.3%) and female students had 2.09 jeans(53.7%) on the average. Male students selected colors of jeans which they don't have, but want to wear once in the order of blue(3.7%), red(21.0%), white(24.1%), black(25.6%), and others(25.6%). Female students selected colors in the order of blue(3.2%), black(15.6%), red(24.8%), white(27.7%) and others(25.6%). In case of the general image about jeans, male students thought the jeans as masculine(1.2%), sexy(3.1%), unisexual(3.2%), active(23.6%), young(29.8%), and comfortable(36.5%) and female students thought it as masculine(0.3%), sexy(3.5%), unisexual(10.4%), young(21.9%), comfortable(28.1%) and active(35.8%). Male students considered torn or holed jeans ill-mannered(10.7%), delinquent, (20.7%)trendy(21.0%), comfortable(22.9%), and dandy(24.7%). Female students think it ill-mannered(3.4%), delinquent7.1%, trendy(17.4%), comfortable(21.1%), and dandy(50.9%). When they purchase jeans, male students choose according to trends(17.9%), don't consider design(19.5%) and look for their own styles(62.6%), female students didn't consider design(5.2%), choose according to trends(22.0%), and look for their own styles(72.5%). The designs of jeans which they usually wear were bell bottom(1.5%), wide-shaped(7.4%), baggy(17.5%), straight-shaped(73.6%) in case of male students. on the other hand, in case of female students, baggy(10.2%), wide-shaped(11.0%), bell bottom(17.0%), and straight-shaped(61.8%). The designs of jeans which they didn't have but want to wear once are wide-shaped(10.1%), bell bottom(13.2%), baggy(20.9%), and straight-shaped(55.2%) in case of male students. On the other hand, females students want to wear baggy(11.6%), wide-shaped(15.0%), straight-shaped(27.6%), and bell bottom(45.8%). The above-mentioned findings illustrated that both male and female students regarded blue as the original color of jeans, but they wanted to wear jeans in colors other than blue. In the past, jeans were considered masculine and unisex, but they viewed jeans as an apparel that was comfortable to wear and made it easier to move. Female students had a higher tendency to be fashionable than male students, and their preference for jeans was consequently different. Jeans manufacturers should take those characteristics into account to produce products in different colors and form.
