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.

We developed a pattern drafting computer program using a popular CAD program for the purpose of the automatic manufacturing and education based on the concept of the easy -order-system which can easily reflect body characteristics and design favors of individuals to the ready-made clothing. The programs were written in Auto LISP which can utilise most of frictions of the Auto CAD, and the result of the design for an full-pleated skirt was shown. Also, we devised an easy way to set the location of reference points by inputting of tangential angle only for the use of the cubic spline curve which can represent body shape very well. Finally, by marking down all of symbols needed in manufacturing process, we completed the automatic pattern drafting program to make it useful as an industrial pattern without any amendment or correction in cutting and sewing operation.

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

The purpose of this study was to develope a pattern drafting method for various somatotype which contribute largely to increase the fitness and comfort of garments. This study had 8 subjects who were college girls who had prominent somatic characteristics. The study was carried out by the following procedures. 1. The 8 subjects who had prominent somatic characteristics were cheesed by photograph- ing. The somatotypes of 8 subjects were classified into Standard somatotype, Turning over somatotype, Bending somatotype and Turning over-Bending somatotype. 2. Under the criterion of the body surface development, the comparative investigation on the pattern and the sensory evaluation were accomplished in the flat pattern method and the draping pattern method. 3. The body surface development of them were made by the draping pattern method. 4. In the result of the comparative investigation and the sensory evaluation, it was found that the flat pattern had better appearance and comfort than the draping pattern, and the draping pattern included more somatic characteristics than the flat pattern. 5. On the basis of those result, the pattern drafting method according to the somatotype was indicated and it was examinated by the clothing experiment. 6. The sensory evaluation for appearance and comfort was applied to evaluate the new basic pattern for four somatotype by comparing it with the conventional basic pattern (Rim, won ja' 5). The result of the sensory evaluation, it was found that the new basic pattern was more suitable for each somatotype than the conventional basic pattern.

The methodology of applying fabric stretch ratio in the grants pattern drafting was evaluated. The experimental fabrics employed in this study were 3 different knit fabrics with various stretch ratio in vertical or horizontal direction. The firm fitting pants pattern was modified by applying the fabric stretch ratio in vertical ana horizontal direction. The computer automatic drafting method was used for pants pattenl alteration. The suitability of the altered pattern was evaluated by the 7 clothing specialists, The results showed that fit of all experimental garments was improved in general. The garment which was constructed with the fabric having large difference between horizontal stretch ratio and vertical stretch ratio showed poor fit at crotch area. This result implies that computer aided pattern alteration is not appropriate when fabric stretch ratio is vary by the fabric directions.

The purpose of this study was to provide basic data for a more functional torso's pattern by analyzing multidimensional anthropometric measurements and the wearing condition. For the functional torso's pattern drafting, the fitness state of basic torso's patterns(4 types) was compared and evaluated from the cross-sectioned overlap maps by $moir{\acute{e}}$ topography. The results were as follows: 1. According to the measurements of four patterns by using the one-dimensional measurement, the amount of ease in girth item for pattern A was the smallest. The ease of clothes was affected by the position of dart, the amount of dart, and the drafting method. 2. As the results of wearing evaluation by $moir{\acute{e}}$ topography method, pattern B had the largest space length for hip part, pattern A, C and D had the largest space length for bust part. Also, in the all measurement items, pattern A had the smallest amount of ease. The space length for bust and waist part of pattern B was smaller than pattern D, but, for abdomen and hip part of pattern B was larger than pattern D. The space length of pattern C was revealed intermediate for all measurement part. 3. The significant difference of space length of each pattern was shown in all parts except bust part(p<.05). The amount of space was affected by the amount of dart, the characteristics of the somatotype, and the drafting method.
