This study set out to analyze the solid shapes of knit flared skirts, which are best represented in a 3-dimensional shape for all knit skirts, according to the seamed and seamless production method and to estimate the silhouettes of knit flared skirts based on the results. It also aimed to help with the introduction and spread of seamless weaving by revising and supplementing potential problems and provide findings that would be put to active use as basic data, thus contributing to the development of original knitwear and offering fundamental materials for the development of the knitting industry. A number of experimental knit flared skirts were made according to skirt angle ($90^{\circ}$ and $180^{\circ}$), gauge (7G, 12G, and 15G), and grain (bias, wale, and radial), including 12 kinds of seamed knit flared skirts and 6 kinds of seamless knit flared skirts. Using a three-dimensional shape measurement system, the investigator measured the cross-sectional shapes of their hemlines. The SPSS 12 Version program was used for statistical processing, and descriptive statistics such as mean and standard deviation were used to compare the seamed and seamless knit flared skirts in the measurements (measurement items) of their solid shapes according to the width, gauges, and grain directions. The central grain direction of seamless knit flared skirts was in a radial form and even hemlines, thus presenting a beautiful appearance and solid shape. The 3-dimensional shapes show that seamless knit flared skirts are superior to seamed ones. The research findings are expected to open a door for Korea's knitting industry to quickly respond to small quantity batch production and additional orders.

West African's traditional looms, weaving and raw materials, structural patterning, dyeing and basic forms of dress were examines in the present study in order to deepen the appreciation of the cultural heritage of West Africa, and to make a contribution to the policy planning for export market developing The research method employed was the analysis f written materials. The study was limited to the traditional clothing habit which is preserved and practicing by them at the present day and the origin and the process of the historical development of those are not included in the scope of the present study. Followings are the results of the study: (1) They have vertical single-heddle loom horizontal or ground single-heddle loom, and double-heddle loom. The width of the cloth produced on the single-heddle loom varies about 38.5cm to 123cm and double-heddle looms all produced on the single-heddle looms all produced narrow strips of cloth varying in width from about 1.3cm to 75cm, although the average is about 10-20cm. (2) Despite the relative simplicity of the llom technology a remarkable variety of textiles are produced. (3) The most popular decorative technique in West African compound weaves is extra-weft patterning which is produced on both single-heddle and double-heddle loom by men and women weavers. Other forms of secondary patterning on textiles in West Africa are dyeing, applique, patchwork and embroidery. (4) Two basic forms of dress have spread throughout West Africa, the poncho (bpibpi) and the wrapper. Some versions of these basic forms are supplemented by western inspired trousers, shirts and blouses coupled with accessories usually complete their traditional outfits. They have a great variety of basic poncho, like as Khasa, Gandura, Tuareg-poncho, Babariga, Rigas (agba-da), Grand-boubou, Afteck, Tagua, buba, Danshike etc. Although West Africa has long been in contact with the peoples of the Nile region as well as the Maghreb and Sahara, both the boubou styles and the wrapper styles appear to have developed with a minimum of outside influence. African Islam was the principal agent for the diffusion of the boubou styles.

The kind, the structure, and the motif of the Chosun dynasty's fabrics found mainfy within the Buddhist statues were studied. The total of 62 pieces of fabrice can be classified chronologically as follows ; 27 pieces in the year of 1431, 20 pieces of 1550, 9 pieces of 1664, and 6 pieces of 1735. These 62 fabrics also categorized by the weaving method as follows; 27 plain weaved, 17 twill weaved, 10 pieces of satine weaved, 7 pieces of Leno weaved, and 1 piece of double weaved fabrics. Most of the studied fabrics were silk, the rest were 2 pieces of yam and 1 piece of cotton, Kyun, Chu, and Cho were the plain weaved silk as Nung and Ki were the twill weaved silk, Satine weaved silk was called as Dan and double weaved silk was called Chikum in the Chosun dynasty. 1. The antique fabrics were composed of mainly silk. This is believed due to the utmost devotion to the buddhist statue as an object of worship. 2. In the fabric's structural point of view, th ecrossed 4-ply threads of warp yarn which is one of Leno weaved can be observed fre-quently in the period of Korea dynasty's fabrics. But it started to disappear in the beginning of Chosun dynasty, since only one piece of Ra could be found in the 1431's fabrics. Keum, one of the double weaved structure is assumed to be extinct from the Korea dynasty. Satin weaved fabrics started to be woven from the latter period of Korea dynasty and was very popular in Chosun dynasty. 3. The widths of fabrics in the Chosun dynasty gradually decreased compared with those of Korea dynasty.

The opening period of Korea was the period of modernisation amidst the conflicts between conservative and progressive sections with penetration of Western powers after 1876. With the opening modernisation accompanied modernisation of education. Missionary schools established by protestant missionaries played a crucial role in educational modernisation in the period of opening. In this article, the process of educational modernisation and the ways in which the ideas of democracy and equality were taught in the earliest schools, Paejae, Ewha, Kyoungsin and Chungsin are analysed through the method of bibliographical investigation of the textbooks used by these schools. No textbook prior to 1900 was found and in general there were no textbooks such as we know today. Usually English reading material and the Bible were the main teaching materials. Teachers kept their own copies of hand-written texts which were translated versions of American textbook. Since the same teacher taught in a number of schools, they shared same curriculum. In the early period, English Bible was taught so that English and the Bible lessons were not separated but gradually history and geography were added. Teaching of Hangul, and Korean history were added to encourage the sense of national identity and patriotism. In the case of Chungsin, for biology class, pupils were sent to Che-jung-won to learn human physiology, chemistry and physics, which shows an emphasis on science education. Vocational education was carried out; in the case of Paejae, a printing workshop was set up enabling students to earn some money at the same time as learning. Also in Kyungsin, skills of woodwork and basket weaving were stressed. Ewha also held a bazaar of the work made in sewing classes. Establishment of missionary schools brought about a great contribution in modernising Korean society and the Christian spiritual education of these schools lay the foundation for building democracy in Korea.
