This comparative study analyzes and compares tight skirt sewing methods which are found in the clothing configuration reference text books available in contemporary universities and which are used in commercially-available domestic consumer products. The study samples included 15 text books and 12 tight skirt consumer products of different brands on sale at three department stores in Seoul each of which had a belt, a back-centered zipper, and back double slits. The findings of the study are summarized as follows: First, text books mainly show very basic sewing methods of using zippers on both sides of the straight-lined waist belt. This indicates that it is necessary for such methods to be complemented so that they cover a recent variety of designs, materials, and sewing machines. For consumer products, the main sewing method is to use a curved waist belt and a console zipper in silhouette running across half the hipbone. Second, consumer products employ three different types of cutting and sewing methods for putting an inseam on the center of the back slit part: to leave the whole inseam hemmed in the back center, to cut the left side of the inseam to the upper part of the back slit, and to cut the inseam to both the upper parts of the back slit. However, a method shown in most of the sampled text books is to cut the inseam of the back center to both the upper parts of the back slit. Third, the way of finishing a bottom edge hem in the text books is to do slip-stitch, herringbone stitch, and slinting hemming, in order after doing over-lock stitch, or to cut the hem on the bias and then slip-stitch, while for the consumer products the most frequently used sewing method is to finish the bottom edge hem by doing secoui-stitch. Finally, while in the text books the method of stitching darts and tucks is used for lining, the main lining method used in consumer products is to make tucks only. Also in the way of stitching the side seams of lining or the seams of the back center, there is a difference between the two sample groups of text books and the consumer products: while the former suggests using both open seams and over-lock stitch, the latter is found to finish the seams using an over-lock stitch only.

This study aims at the improvement of sewing function through understandings of dynamic property about the sewing methods and the thread material selection in knitwear. The tensile strength and shear of KES-FB and the Instron were measured for the analysis of the mechanical properties. The knit cloth was structured In the plain stitch, $1\times1$ rib stitch and $2\times1$ rib stitch with the combination of wool and cotton. With regard to the sewing method, intralooping and interlacing were applied. For thread materials, polyester, cotton, wool and silk were used. Since silk has the lowest extension and similar values regardless of its construction in intralooping, it is available knit apparel with uniform elastic recoverv. It also has small shearing resistance. It can be used in apparel which needs big mobility, but it causes rutting problem. Therefore, it is suitable to use intralooping. When the same sewing yarn and textile are use, it can lower shearing resistance and extension in intralooping, Since wool needs a lot of extension energy and it can be cut, intralooping is more suitable than interlacing in sewing of wool. In interlacing using polyester, extension and shearing resistance are high. Therefore, it is suitable for knit sewing with high massing. Silk is not suitable for interlacing since it can be rut. Even though knit materials are different, the RT values of polyester and cotton are similar in same construction. Therefore, they can be substituted each other considering resilience after sewing.

In the era of the fourth industrial revolution, many production plants are gradually evolving into smart factories that apply information and communication technology to manufacturing, distribution, production, and quality management. The conversion from conventional factories to smart factories has resulted in the automation of production sites using the internet and the internet of things (IoT) technology. Thus, labor-intensive production can easily collect necessary information. However, implementing a smart factory required a significant amount of time, effort, and money. In particular, labor-intensive production industries are not automated, and productivity is determined by human skill. A representative industry of such industries is sewing the industry. In the sewing industry, wherein productivity is determined by the operator's skills. This study suggests that production performance, inventory management and product delivery of the sewing industries can be managed efficiently with existing production method by using smart buttons incorporating IoT functions, without using automated machinery.

In this paper, we present a BLDC Motor control for needle positioning and velocity control in the industrial sewing machine. In the industrial sewing machine, the fast acceleration control is needed, especially for a person who has a skill in operation of sewing machine for more products. And it is also needed to have a less noise and vibration. But the system which is made in a low price has no feedback system for a current control. Therefore we propose the method of velocity pattern that has an acceleration of velocity and Anti-windup algorithm. By the experiment, we confirmed that these manner have a good performance for low noise, low vibration and fast acceleration in the industrial sewing machine.

The primary goal of most clothing-related textbooks currently used in colleges in Korea is to determine how to plan and develop basic patterns. Therefore, they are limited in understanding the patterns and sewing methods of practical, ready-made clothes that are continuously being upgraded. According to previous studies regarding sewing methods in clothing construction textbooks, tight skirt, tailored jacket, and shirt sewing methods have been explained. However, there has been no study on the sewing methods of slacks. Therefore, this study attempted to suggest basic data needed for making slacks through a comparative analysis of their sewing methods for educational purposes. In addition, this paper is meaningful in that it complements clothing construction-related textbooks according to the current trends of diverse clothing design and materials and develops learning materials for the construction of clothes, which are applicable to practice. In this study, the sewing methods and construction procedures of slacks stated in clothing construction textbooks that are currently used in colleges and fashion-related educational institutes were analyzed. Among a total of 47 textbooks on the market, 15 books that cover the cutting and sewing methods of slacks and are suitable to slacks design were used. According to the analysis, most textbooks described the production methods only, without explanation of materials, which can affect clothing construction methods. Because there is a large difference in pocket and slacks procedures by textbook, there is a need for a standardized construction method with changes in clothing materials and design.

The purpose of this study was to examine the sewing construction of a double robe, the difference between the single and double robe, and the size and construction method of the double robe through a close analysis of a replica to facilitate a better understanding of the robe making in late Chosun dynasty. The results were as follows: 1. There was no significant difference in the design and sewing method between the girl's robe and an adult's even though the girl's robe was much smaller. 2. The girl's robe differed from its modern counterparts in some respects: unlike modem robes, Chungyun's robe consisted of two-layers in which the four layers were sewn together and it could be seen most clearly in the way the collar was stitched only onto the outer layer. The two layers seemed to be put on successively since they were not sewn together. The inner collars of the two robes were sewn together when the maker put on a coat string to the outer robe, and the two robes were put together with hemming and blind stitch at the top of the outer collars to make the robe formally stable, which clearly distinguished the princess' robe from a single, for example, four-layered robe. The robe was constructed using traditional sewing methods including broad stitch, back stitch, hemming, and blind stitch, and each stitch was only about 1 mm wide. 3. The maker of the robe managed to construct a formally stable and aesthetically satisfactory robe with the least amount of fabric and proper sewing methods.

This study was conducted on 2016 $1^{st}$ and $2^{nd}$ grade middle school students in order to investigate of their perceptions and needs on sewing practice class, which had been experienced during their $6^{th}$ grade elementary school year. Implications and improvement for sewing practice class to be drawn from this study. The findings are as follows: Firstly, the levels of satisfaction with the practice contents and teaching learning method were higher than the median value(3.00). Among the subareas of class evaluation, participation scored the highest average, followed by interest, difficulty, necessity, importance, and utilization. In the entire subareas, girl students have more positive perceptions on sewing practice classes than boy students. Secondly, satisfaction with the practice contents has an effect on all subareas of class evaluation. The satisfaction with the teaching learning method has an effect on participation, interest, importance and utilization. Lastly, as for the practice contents, they would prefer household items and ornament, and want to choose sizes freely. As for students' needs for a new teaching learning method through which students are allowed to freely make objects or create works through a group activity, it was higher than the median value. This study showed that practice contents and teaching learning method are important factors that affect class evaluation. This study suggested that sewing practice class should be conducted freely choosing of practice contents, making the group works, group or student-led activities. If sewing practice class is designed in consideration of the results and students' needs for class, students' perceptions on class is expected to change in a positive way.
