Developed in this paper is a standard time data for shirt sewing operations in the apparel-making industry. Since this data is made of formula developed for each unit operation and includes the formula for the machine time calculation, users could use it for obtaining the normal or standard time without any special efforts. In addition, this data handles the variations due to the design changes of a shirt through the parameters in the formula. compared with the MTM-1. The standard time data developed is shown to be easier and faster in determining the standard time with acceptable accuracy.

The purpose of this study is to compare Jegory with Simii, and to understand the construction of Jegory, assuming that Jegory is related to Simii system. The results obtained are as follows ; 1. Teie-ku-li was the first record among the name of Jegory in literature, was called about A.D. 1408. 2, When Jegory and Simii were cut, front-back width and sleeve length standarded on the width of cloth. 3. The cutting of Jegory disposed to seperate right and left width, to connect front and back width up to the middle term of Chosen Dynasty Period. 4. The sewing order of the Simii was Dungsol-Jindong-Baerae-Sougu. The sewing order of the Jegory in $\ulcorner$ The Book of Chosen sewing$\lrcorner$ was Shoulder-Jindong-Baerae-Sup-Dungsol-Kit and in literature of 1960's it was similar to Simii. 5. The lined clothes in $\ulcorner$The Book of Chosen Sewing$\lrcorner$ was sewn to put the inside in the surface, different from the literature of 1960's. 6. In Chosen Dynasty Period the shape of Simii depended on $\ulcorner$Moon Kong Ka Rye$\lrcorner$, but it was changed to similar to Jegory in the latter term. 7. The empty void in Jegory offers usefulness. It relates to Oriental negativism that yin is more useful than yang.

The purpose of this study is to examine the influences of learners' self-efficacy on class satisfaction in learning practical basic sewing. Questionnaires were distributed to 181 college women students living in the areas of Deagu Metropolitan City and Gyeongbuk Province. The data obtained were analyzed by using various statistical tools: frequency, factor analysis, reliability analysis, correlation analysis, and multiple regression. The self efficacy of learners of practical basic sewing were made up of five factors: ability to manage interpersonal relationships, ability to deal with assigned tasks, anxiety, challenging spirit, and fear. Class satisfaction was composed of the following factors such as interest in class, professors' ability, achievement of class objectives, connectivity, preparation for class, preference for practices, and perfectibility. This study indicated the correlations between sub-variables of learners' self efficacy and class satisfaction. In other words, the higher were the levels of ability to manage interpersonal relationships, and ability to deal with assigned tasks in self efficacy, the higher were the levels of interest in class, professors' ability, achievement of class objectives, preference for practices, and perfectibility in class satisfaction. The factors of ability to deal with assigned tasks, anxiety, and challenging spirit, in learners' self efficacy were found to have statistically significant effects on the achievement of class objectives. The factor of ability to deal with assigned tasks in self efficacy had a statistically significant influence on professors' ability. The factors of ability to deal with assigned tasks, anxiety, challenging spirit and fear were found to have statistically significant effects on all the factors of class satisfaction.

The contents of clothing and textiles area of elementary home economics textbooks from 1948 to 1955 were investigated. Home economics of elementary school education in those days corresponds to practice acts of elementary school education in present. Practical acts has the all-around concepts of the agriculture, industry and home economics Also the knowledge or skill for actual life are teamed. Practical acts education was started from lessons of sewing for women under title of 'jaebong'. It can be said that practical acts education was started from clothing and textiles area. The home economics elementary textbooks of the year 1948 were composed of 21 units for 5th grade and 22 units for 6th grade. The textbook for 5th grade of 1953 was composed of 19 units, and one for 6th grade of 1955 was composed of 18 units. The clothing and textiles area accounts for 38.6% in 5th grade textbook, for 32% in 6th grade textbook of 1948 and for 31% in 5th grade of 1953 and 6th grade textbooks of 1955. The textbook contents of clothing and textiles area were classified into five fields of sewing, knitting. patching, embroidering and care. In 1948, textbooks were placed a great deal of weight on sewing field education as 7 units of 15 units. The 7 units for sewing fields have suitable connection to develop. But, in the case of knitting, patching or care, just groundwork of each field was included for application to actual life without vertical connection. The contents of textbooks for clothing and textiles area in 1953 and 1955 were much alike with those in 1948.

The purpose of this paper is to obtain an accurate nonlinear system model to test various control schemes for a motion control system that requires high speed, robustness and accuracy. An industrial sewing machine equipped with a Brushless DC motor is considered. It is modeled by a neural network that is configured as an output-error dynamical system. The identified model is essentially a one step ahead prediction structure in which past inputs and outputs are used to calculate the current output. Using the model, a 2 degree-of-freedom PID controller to compensate the effects of disturbance without degrading tracking performance has been de-signed. In this experiment, it is not preferable for safety reasons to tune the controller online on the actual machinery. Experimental results confirm that the model is a good approximation of sewing machine dynamics and that the proposed control methodology is effective.

The number of Ryu Ji Kyung's costumes that have been discovered is small but includes various kinds of coat. These coats have become important clues when trying to determine styles of coat that were present in the mid-17he composition of the costumes found were various, including unlined, lined, padded and quilted variations. Unlined clothes were sewed using broad-stitching, hemming, half backstitching, and backstitching. The unique sewing style of the 17th century was shown in Ryu Ji Kyung's costumes. Seams on the back of one coat were not connected but rather sewed as a whole because of the width of the cloth. There was a more elaborate sewing style on lined clothes than on unlined clothes, alongside the use of selvage on the reverse of the costumes, marking the face not by using other clothes, but by the sewing line. Because of their to kit types, the width of the sleeves, the presence of a Cheolrik string, the ratio of the upper jacket to the bottom skirt, and the width between the armpits and bottom hems in Jungchimak, Ryu Ji Kyung's clothes can be used as exemplary models of mid-17th century clothing.

The purpose of this paper is to make it easy to reproduce the Pattern and sewing technique of men's coat in 18th century. which are modified in order to be made readily available in Korean theatre costume. The investigation was performed in three steps. 1st, The papers and records about development and change of men's coats were reviewed. End; The whole process of the way how to make a typical 18th century men's coats were sewn. 3rd ; The modification or revision into the more simplified pattern using by CAD system and sewing technique were suggested in detail. The size of the pattern in the original one, which we chose for this research, was generally small. with the side line being moved back a little. Moreover, arm movements were severely restricted because of the small arm-hole. The problems of original pattern were corrected by making both front and back pattern snug and side line being moved to the front, and making arm-hole wider. In the sewing technique, the simple way how to use of Padding, inter-linings and linings and to create the most noticeable figure of 18th century men's coat. This article may help theatre costume production in Korean performing art.
