Najang was the central Seori, affiliated to the Ministry of War during the Joseon dynasty. The objective of this study is to research the existing authentic Najang costumes from the late-Joseon dynasty by examining factors, such as the composition of the costume, size, and method of creation, and attempt to replicate it. The Leipzig Grassi Museum in Germany possesses an official uniform of Najang from the late-Joseon dynasty, and we visited the museum in May of 2013 to examine it for the study. Written records, or Uigwe, and other pictorial data from the Joseon Dynastry describe the Najang wearing black or navy clothing with white decoration and pointy hats. The most notable characteristic of the Najang uniform is that it has the cotton cords pattern. The hat has a brass ball attached, which was worn with the ball facing the front in the early Joseon Dynasty, and was worn facing the back in the later years. They usually wore black head cloths (Heuk-geon), but would attach feathers on the black hats (Heuk-rip) for special occasions. The Najang uniform preserved in the Leipsiz Grassi Muesim does not exist in Korea. It is made of cotton. The cotton cord pattern of the uniform of Najang was made using single-ply cords and double-ply cords. The hat worn by Najang is in a form of a cone that becomes narrower towards the top or is in a form with wide and open end. It was made of oiled paper covered with hemp, and two circular metal disks were attatched at the rear.

Tire codes are made of materials such as hemp, cotton, rayon, nylon, steel, polyester, glass, and aramid are fiber reinforcement materials that go inside rubber to increase durability, driveability, and stability of vehicle tires. The reinforcement of the tire cord may construct a composite material using tires such as automobiles, trucks, aircraft, bicycles, and fibrous materials such as electric belts and hoses as reinforcement materials. Therefore, it is essential to ensure that the adhesive force between the rubber and the reinforced fiber exhibits the desired physical properties in the rubber composite material made of a rubber matrix with reinforced fibers. This study is a study on the heat treatment conditions for improving the adhesion strength of the tire cord and the reinforced fiber for tires. The core technology of the drying process is a uniform drying technology, which has a great influence on the quality of the reinforcement. Therefore, the uniform airflow distribution is determined by the geometry and operating conditions of the dryer. Therefore, this study carried out a numerical analysis of the shape of a drying nozzle for improving the performance of hot air drying in a dryer used for drying the coated reinforced fibers. In addition, the flow characteristics were examined through numerical analysis of the study on the change in the shape of the chamber affecting drying.

The modems who lives complicated society, the silence which the Orient thought asserts leads and to get comfortable. It is becoming, the like this social atmosphere will in the interest regarding a manual example and the Orient material, the use of the embroidery textile goods is increasing specially. The purpose of this article is to suggest a model for development of machine embroidery fabric material and highly value added apparel industries. The multi-headed embroidery machine where the application scope is wide from the dissertation, we are requested' NaNa company'. The multiheaded embroidery machine uses TAJIMA TMFD-G620 and SUNSTAR SWF-／B-WD(X) 620-100 the embroidery textile uses the silk, the cotton and the synthesis fertile goods etc 24 type, the embroidery thread Maraton thread(viscose rayon 100％) with used the cord. The 8 Korean motives are made on 23 fabrics, 6 of which are full-sized manufactured one-pieces and the other 17 of which are produced to home interior goods such as curtains or fashion accessories like handbags as simulations. Among the products, the pattern-4-1 and the pattern-4-2 are contracted with local fashion industry, and the pattern-1-1～3 are dealing with other companies in Japan. The computerized machine-embroidering and simulation producing of fashion items are available to reduce the cost in making samples and transfer the old labor ＆ toil-centered industry into the new technique ＆ knowledge centered one.
