This study suggests designs for fashion-cultural products that can communicate the uniqueness of Korean traditional culture. To this end, motives and printing patterns were created based on the formative beauty of traditional sewing crafts. A literature review was completed to identify characteristics of Korean traditional sewing, and the motives were developed through Adobe Illustrator CS4 and Adobe Photoshop CS4. Those motives were applied to handkerchiefs, neckties, pouches, and handbags. The sewing crafts used in this study included thimbles, bobbins, and chumoni (a Korean traditional pouch). The motives were produced in a manner that best exemplified the unique formative beauty of the sewing crafts while also presenting modern images of the crafts. The motives from thimbles reflected the lateral side of their originals, while the motives from bobbins adopted fan- or rectangular-shaped bobbins. The motives from chumoni were based on Duruchumoni and Guichumoni. A total of 12 motives were developed, and a total of 36 textile designs were suggested based on those motives. A total of 42 designs for fashion-cultural products, including handkerchiefs, neckties, pouches and handbags, were developed. Among them, motives applied to handkerchiefs were expanded to apply to scarfs, as well.

The history of paper folding had continued before that the paper manufacturing technique was spread in the 3rd century and it was used for witchcrafts and rituals. Fold means as was used with the word Cheop and Jeopji. In the Three Kingdoms period, the conical hat with fabric spread as customs, then it was made of the paper that led the popularization of paper folding form the early Joseon Dynasty. Paper crafts and living things with paper are mostly derived from fabrics except the paper written for saint's name related God. In the period of the tribe nation, witchcrafts and rituals brought to Japan via the Korean Peninsula, as a result Kami which means God in Japanese that becomes the paper. The first folding fan was made to develop from the fan, Baekseopsun in the end of Goryeo Dynasty. It was an outstanding application of paper folding crafts. Since the early Joseon Dynasty, paper flower folding has considered as the virtue of savings and has developed one of the Korean traditional paper arts. Paper folding has also developed in the practical uses like the other Korean paper arts but paper folding that was developed as seasonal customs, playing or religious purpose showed a different trend from Korean paper arts.

WIG crafts are high speed vessels with the features of a dynamic supported craft. These crafts, which are predominantly lightweight and operate at substantially greater speeds than conventional craft, could not be accommodated under traditional maritime safety instruments. WIG crafts inherently possess more hazard factors than conventional ships because of their relatively high speed, lightweight, and navigational characteristics, and an accident is likely to cause damage to the ship and a high loss of life. Because WIG crafts are composed of many systems and subsystems, the safety assessment of a WIG must use a commercial software system in the design stage. This paper reviews a safety assessment process and methodology proposed by the IMO interim guideline, which were developed in view of the configuration of WIG crafts. This safety assessment system was developed to fit the WIG's safety assessment process using a reliability analysis system widely used in commercial systems. The FHA was performed on the functional hazards of systems in the conceptual design stage.

4-(p-Chlorophenyl)tetralone (6) and 7-chloro-5-(p-chlorophenyl)tetralone (9) are key intermediates for the development of benzazepinone derivative haftens. These compounds could be synthesized from 4-phenyltetralone derivatives by triflic acid catalyzed Friedel-Crafts reaction. The reaction mechanism of Friedel-Crafts alkylation/acylation with lactones in triflic acid is presented. According to our tentative research, ring opening of protonated lactone (2) occurs in alkyl cleavage and the rate of the reaction is not dependent on concentration of triflic acid. So, alkylation of lactone in Friedel-Crafts reaction is presumed to be $A_{AL}$ 1. In second step, intramolecular acylation of the intermediates 4 to 6, 4 can be transformed to a triflic acid-carboxylic anhydride and then the cyclization is undergone after leaving of the triflate anion.

A facile method for tolmetin, which is a potent antiinflammatory agent, is described. Friedel-Crafts reaction of 1-methylpyrrole with ethyl ${\alpha}-chloro-{\alpha}-(methylthio)acetate$ (1) gave ethyl ${\alpha}-methylthio$-1-methyl-2-pyrroleacetate (4), which was readily converted into ethyl 1-methyl-2-pyrroleacetate (5) by reductive desulfurization with zinc dust in acetic acid. Tolmetin was synthesized by Friedel-Crafts acylation of (5) with p-toluoyl chloride, followed by hydrolysis of the resultant ethyl 5-(p-toluoyl)-1-methylpyrrole-2-acetate (6).

Crafts in our country designated as an Important Intangible Cultural Property. Are protected, but not being utilized less than in everyday life. But now that the culture industry has important strategic and cultural factors that influence the competitiveness of the industrial era was. So on the activation of traditional crafts growing interest and demand, but the nature of traditional crafts are still several issues that are faced. Of course, for the protection and industrial policies and institutional mechanisms, but not without a very negative and is weak. Therefore, preservation of traditional crafts and industrial use of the technology to effectively carry out two tasks have the policy should be sought from every angle. In this study, the kind of important intangible cultural heritage of the traditional craft techniques from various angles by category, by systematically analyze the characteristics of modern man with the utilization of real-world craftsmanship with the highest tradition of finding and preserving traditional craft skills in the limit popular and can be out of the technology industry as a potential development is proposed.
