  • This study devised and drew custom sleeve patterns by using a regression equation with the data from 7 models along with the sleeve that was slightly modified to make the general-purpose sleeve pattern. To devise a general-purpose sleeve pattern, the sleeve pattern was drawn as an object for comparison by applying the Bunka drafting system (sleeve pattern by the Bunka drafting system) to the basic upper garment. Actual sleeves, made by using the three types of patterns above, were created and tested by models. Next, 30 panel members participated in a sight test of the compatibility of the sleeves to examine the validity of the sleeve drafting method acquired using the regression equation. The test proved that the custom sleeve pattern and the general-purpose sleeve pattern were more suitable for the characteristics of arm structures. Thus, the new sleeve-cap part drafting method using the regression equation was shown to have validity. As a result, since a very significant correlation was obtained for the body measurement figures and the basic pattern of the adequate basic pattern of the sleeves, this study concludes that it is possible to come up with primary data that can be widely used by increasing the number of subjects.

  • The aims of this study are to develop CAI programs for bodice and sleeve pattern drafting for the 3rd grade students in a middle school and to compare the students’achievement degree in using traditional teaching method with that in using CAI programs. On the basis of results above the direction and possibility of using computers in education home economics is another aim. For this study, after the programs are developed, which is on the model of middle school text book, one hundred girl students of 2nd grade of middle school in Songpa Gu, Seoul, who have never given Bodice and Sleep Pattern Drafting lesson are chosen. The students are divided into two groups: one is called comparison group, which is taught by traditional method, the other, experimental group, which is taught by CAI programs. To evalute the learning achivement degree, evaluation test, effectiveness of learning and interest degree test and time test are given. Questionaire investigation about CAI program is given to experimental group. The results of this study are as follows: 1. CAI programs on pattern drafting are developed and can be used in the class. 2. In the tests of achievement degree, of effectiveness, and of interest the experimental group gets higher scores than the comparison group. 3. In the time test about how many students can draft the pattern in a given time, in every step more students in experimental group finished drafting than the comparison group. 4. The students showed interest in CAI programs and played an active part in the using computers. Therefore, using CAI programs in the class of pattern drafting saved the teachers lots of difficulties and enables individual learning improving the effectiveness of learning. I hope the studies of CAI will be established in other field as well as Home Economics, especially clothing part, and computers will be used lively

  • This study is conducted to improve the fitness of Air Force winter service uniforms pants through the development of a pants pattern drafting method and automatic pattern drafting program for mass customization. The initial study pattern drafting method is formed through an analyses of 4 kinds of conventional pants pattern drafting methods for education and 3 kinds of conventional pants patterns of Air Force apparels. The initial study pattern drafting method is converted into the final study pattern drafting method after twice conducting a wearing test. To verify the final study pants pattern, a motion adaptability evaluation, an ease amount evaluation and an appearance evaluation are conducted. The results of the final study patterns were better than conventional winter service uniforms in the motion adaptability evaluation and the appearance evaluation. However, the results show similar values between the final study patterns and conventional winter service uniform patterns in the ease amount evaluation. An automatic pattern drafting program was developed based on the final study pattern drafting method. The program allowed the achievement of customized pants patterns through the placement of customer body sizes into the size input window. It also provided two kinds of ease amount and two kinds of waist belt level options.

  • The need for children's formal wear is growing as parents take their children into formal occasions more often than before. Yet there are some problems to be solved in order to generalize about children's formal wear such as high price and the development of patterns for better fit and design. Mothers of boys were surveyed to find out the needs, complaints, and required improvements of boy's formal wear. Pattern designers of children's formal wear brands were interviewed to determine the size specifications, pattern drafting methods and design features of each brand. Based on these results, several pattern drafting methods were selected. Jackets and pants for 9-year-olds were made by each pattern drafting method using the us standard size. They were compared through wearing test to improve the fit. As a result, pattern drafting methods for children's tailored suits and two formal jackets were suggested.

  • Countries have different brassiere patterns, and this study produced and compared 3/4 brassiere patterns from different countries to determine the difference in patterns, and to investigate the stress distribution and shape of cross section while wearing brassieres using 3D virtual fitting system. Despite the growing interest in underwear, there is a lack of related books and research on brassiere patterns, which causes the difference in sizes and pattern drafting methods by countries. Thus, research on this is needed. 3D virtual fitting system has been introduced to compare patterns, thereby improving visible effects and reducing the loss in cost caused by underwear pattern fitting test. According to the result of pattern analysis, The Secoli type exhibited the least breast cover rate (14.9 cm), while the largest cover rate was shown in Christina and ESMOD types (17.7 cm). It is believed that the difference in pattern drafting causes the difference in the total length of a brassiere. Furthermore, the Secoli, Moda Burgo, and ESMOD brassieres drafted from basic bodice pattern were found to be longer than the Christina and Han Sunmi brassieres attained from direct pattern drafting. Moreover, the darts' volume of upper and lower cups in Christina and Han Sunmi types was similar in shape. The shapes of cradle drafted from basic bodice pattern were a straight line, while those from direct drafting formed a curved shape. In fitting multiple cross sections, the Secoli, Moda Burgo, and ESMOD brassieres had gaps between the brassieres and the body. Among these, the largest number of gaps was observed in the ESMOD type pattern. This study aimed at performing comparative analysis of various brassieres' pattern drafting types as a basic research for developing a brassiere pattern drafting type.
