The Belgian textile wallcovering has the following background. The unique oceanic climate is optimized for flax. Beginning in the thirteenth century, British wool was produced for export to Britain or neighboring countries. Since the 15th century, Flemish paintings were influenced by color implementations, and these colors have influenced the developments of tapestry and art. Since that time, tapestry and paintings combined with paper technologies and Oriental civilizations, such as silk, that had been developed through trade ports, have been transformed into the form of current wallcoverings. Belgium produces the highest quality textile wallcovering using natural materials i.e., a combination of irregular and modern materials, and the implementation of different colors. The Belgian textile wallcovering is also a good representation of nature at the Heimtextil 2018, It provides a wide range of colors while retaining the best styles for wallcoverings in Belgium. The characteristics of Belgian wall coverings are: First, the high proportion of achromatic colors, especially the white ones, are analyzed for current trends. Second, it expresses the characteristics of materials by using only one material. This not only shows a high level of understanding of natural materials, but also shows a high level of development in terms of processing technology. Thirdly, linen was made into a formative expression using wrinkle processing and by printing geometric patterns, the rough texture of natural materials was expressed in harmony with modern patterns.

Dyeability of microbial violacein produced from Chromobacterum violaceum CV107 on to multifiber fabrics has been studied. The bluish-purple colourants were produced by cultivation of Chromobacterum violaceum using LB liquid medium for 2 days. The colourant was extracted with 80% acetone and identified as violacein by LC/MS analysis. The violacein could be dyed on not only natural fibers such as Cotton, Silk and Wool but also synthetic fibers such as Diacetate, Triacetate, Creslan 61 and Nylon 66. Maximum K/S values were shown at 540-580 nm according to different fiber with color appearance of purple or blue. An optimum pH and temperature under dyeing condition were 10 and $70^{\circ}C$, respectively. Any mordants were not improved colour density and quality on various fabrics. From this studies, pigments produced microbe have a high potentials for natural dyeing on fabrics. Finally, development of new colourants from microbe has made a possible change for new dyeing field in respects of eco-friend and repeatability of natural dyeing for apparels.

The research was conducted to quantify farm and household characteristics of sheep farmers, evaluate farmer access to and the effectiveness of livestock services in sheep farming areas, and examine regional constraints to improving sheep productivity and profitability in Nepal. A rapid diagnostic socioeconomic survey of 200 sheep farmers was carried out in 1996 and all four ecological regions (Trans-Himalayan, Mountains, Hills and Terai), each with a distinct local sheep breed, were represented in the survey. Six major constraints were identified: (a) poor performance of local sheep breeds, (b) a serious seasonal deficit of pasture and other feed, (c) the lack of an organized market for wool and meat, (d) poor access to agricultural credit, (e) primitive shearing equipment, and (f) an inadequate supply of drinking water for sheep. Strategies to assist farmers develop their sheep management skills, improve access and quality of support services, improved technology adaptable to local conditions and effective linkages with local carpet and meat industry are likely to overcome the constraints and alleviate persistent poverty faced by sheep farmers in Nepal.

Embroidery is one of the oldest methods of textiles surface decoration. The masterpiece "Tapisserie de Bayeux," is one of the earliest Medieval embroideries. Embroidery was popular on a broad scale with introduction of what was called Opus Anglicanum("English work") in the 13th century. France had been producing sophisticated embroideries since the 16th century. England was the country producing the greatest quantity of embroideries of the best quality in the 17th century. Until the 17th century, the Church was the most important patron of needlework. Then a shift in emphasis occurred towards the domestic embroidery. English 17th century domestic embroidery reached a high point of technical brilliance and charm. In France, embroidery was produced on hangings as well as costume. 18th century interest in embellishing the domestic environment, embroideries became much more finely detailed than those of the 17th century with the use of finer wool and silk threads. French silk were the finest in the world, and their embroidery was arguably equally fine both in furnishing textiles and on costumes. "Art Needlework" was the major movement in embroidery in the late 19th century. The Royal School of Needlework was founded in 1872, followed by similar institutions around Britan. Splendid fashion embroidery of French haut-couture that was represented to Lesage atelier in 20th century.

The purpose of this study was to investigate the actual wearing conditions and the preferences of knit wear school uniforms. The subjects were 480 high school girls from 6 high schools placed in Daejeon. The method of study is a survey consisted of actual wearing conditions questionnaires, preferences questionnaires, and demographic attribution. Data was analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS 12.0 program. The results of study are as follows. First, high school girls over 90% wearing knit wear school uniforms were satisfied with current knit wear school uniforms(navy color, V-neck, and wool mixed). Second, high school girls preferred 100% cotton material and black/white/gray color group. The style of knit wear school uniforms was most preferred monochrome cardigan with cable pattern. High school girls wanted to show neat image by knit wear school uniforms and to diversify the style of them. Third, the differences of preferences between groups, they were wearing knit wear school uniforms(A group) or not(B group), were about pattern and improvement. A group preferred school mark pattern, and wanted to improve the quality and after service. B group preferred monochrome cable pattern, and wanted to diversify the style. Both groups wanted to wear knit wear school uniforms because knit wear was 'warm' and 'comfort'. Consequently, knit wear school uniforms will help high school girls express individuality and beauty.

Recently, a bed company detected a radon more than Red Politics and became a hot topic of conversation. This has led to increased interest in radon, and a number of free-of-charge bodies have also been established to recognize the dangers of radon. In addition, the Korean Institute of Geological and Resource Research is planning to assist the installation of radon alarm systems in 10,000 households nationwide, free of charge. Since radon is a colorless, odorless and tasteless gas that causes lung cancer, it aims to reduce lung cancer incidence by absorbing radon using bamboo activated carbon as a way to reduce it. Due to the use of bamboo activated carbon, radon concentration per hour tends to decrease as substitution rate increases, and table flow tends to decrease as substitution rate increases. Through this experiment, 30% of the replacement rate of bamboo activated carbon is judged to be the most suitable replacement rate.

The tool wear and failure in automatic production system directly influences the quality and productivity of a product, thus it is essential to monitor the tool state in real time. For such purpose, an ART2-based remote monitoring system has been developed to predict the appropriate tool change time in accordance with the tool wear, and this study aims to experimently find the relationship between the tool wear and the monitoring signals in cutting processes. Also, the roughness of workpiece according to the wool wear is examined. Here, the tool wear is indirectly monitored by signals from a vibration senor attached to a machining center. and the wear dimension is measured by a microscope at the start, midways and the end of a cutting process. A series of experiments are carried out with various feedrates and spindle speeds, and the results show that the sensor signal properly represents the degree of wear of a tool being used, and the roughnesses measured has direct relation with the tool wear dimension. Thus, it is concluded that the monitoring signals from the vibration sensor can be used as a useful measure for the tool wear monitoring.

This paper presents a machinability evaluation of Inconel 718 material when using a new uniform-temperature indirect cooling method that incorporates constant-pressure liquid nitrogen (LN2). The flank wear of a TiAlN coated tool used with this indirect cooling system was much lower than that of the tool used with dry machining under all machining conditions. Also, the surface roughness resulting from machining with this indirect method was far less than that of a dry machined surface after the same cutting time. Reduced heat generation and uniform temperature in turning operations play important roles in tool life and surface quality.

Black garments can lose color, image, and be the main cause of color staining when washed with other laundry that can cause color contamination from interaction with other garments. To know the fiber-based dye fastness for colored garments, 4-5 pieces of various fibers of different fabrics were selected; cotton, linen, wool, silk, rayon, acetate, polyester, and nylon. To determine the colorfastness to washing and crocking, the black fabrics were washed with alkali and neutral detergents under the Laund-O-Meter method under the Crockmeter method. In an alkali detergent laundering conditions, most colored samples did not undergo color or light fastness. However, most of the stained fabrics slightly changed in K/S values while other samples underwent severe changes. With neutral detergent laundering, sample fabrics underwent less shrinking, and had less naps. The stained fabrics also underwent less change in K/S values. With time-repeatedly-washing the original sample went through colorfastness to lose color. In crocking fastness, most samples produced good to excellent results under dry conditions but produced relatively low crocking fastness under wet conditions. Natural fibers especially showed lower crocking fastness than artificial fibers. In conclusion, garments of the same color should be laundered together. The black garments that are washed using neutral detergents can decrease the amount of damage from color change. While it is the responsibility of garment producers to provide appropriate quality indications they should also provide adequate instructions for consumers to understand and appropriately cope with the quality indications in order to contribute to establishing a correct laundering method.
