  • Generally, a fixed type guide-bush system is installed during machining miniature work-pieces with high precision in the multi-task CNC lathe. But a conventional guide-bush system does not provide a constant clamping force under the condition of varying work-piece diameters. It is important to maintain a constant clamping force for guaranteeing machining precision. This paper proposes a new guide-bush system with a pneumatic clamping device for the CNC Swiss-turn lathe to keep constant clamping force with changes in work-piece diameters. Through performance tests, new clamping system developed in the study showed better machining precision at the cost of a small increase in the temperature of the system than conventional systems due to an increase in the frictional heat and a change in the heat transfer route.

  • The most distinctive feature of the costumes of the Arctic regions from Alaska to Siberia centering around the Bering Sea connecting Asia to North America, is that each tribe makes clothes adequate to the climate and their lifestyles with animal hides obtained from hunting in their habitation. Furs or fish skins, the main materials for clothing, are characteristically cut into many pieces, and thus piece-joining patchwork is used to make or decorate garments. Patchwork is the technique that can create new designs with 3-dimensional and various combinations by modifying the simple materials, and also has the advantage of fitting the body without a certain cut line. Therefore, the patchwork found in the Arctic costumes may be developed from folk costume designs with limited materials like fur into new ones for modern or future costumes.

  • This study analyzed the montage pattern of e-book in a bid to include e-book in the film language system. To this end, this study targeted three pieces of e-books which reproduced the animation for theater use of Disney Company. This study did research on characteristics of montage in films, and kinds of film vectors, and defined it as 'Montage of Experience' according to media characteristics of e-book. This study deducted the montage pattern of 3 sorts of classification, and 10 sorts of detailed classification by doing research on the analysis object. This study has a significance in that it pioneers a new perspective in e-book research which has been biased towards a functional perspective. Analysis of the point of contact where the existing visual media, and new media meet with each other could be a driving force promoting the growth of the relevant industry, and this study thinks that the analysis of the point of contact is the research which is helpful to working out qualitative improvement of e-book contents.

  • This study is to study the peculiar world of work that endeavored the stage setting and costume production in Ballet-russe centered around one of 20th representative artist Pablo Picasso and Diaghilev. Picasso worked four pieces ballets such as parade, Le Tricorne, Puchnella, and Le train bleu with Diaghilev. The originality of costume was well represented without losing the whole work's sense of unity. and designed foreasy movement as well as visual effect. As cubic is most common in parade especially, cubic stave costume were introduced at dancing costume of Paris manager and New York manager flrst time in Ballet's history. Picasso used the Cubism for dancer's beautiful appearance and primary color and decoration for oriental feeling. Picasso pursued the beauty and action at the same tome, and tried to represent the stage setting, impersonation and costume towards units, so the Importance of his work has still been referring.

  • The first introduction of reformed Korean traditional cloth in was started in the age of civilization and until liberation from imperialism it was made a reformation in faculty from Korean traditional clothing. And by 1980s western style costume took lead but after Asian Game in 1986 and Seoul Olympic in 1988 Korean traditional beauty was added to costume and there were various attempt to produce truly reformed Korean traditional clothing. The present condition of reformed Korean traditional clothing in 1990s are like this : 1) Most of reformed Korean traditional clothing ships could not fractionalize customers. So it needs to subdivide and specialize customer and investment to improvement of design. 2) A large percentage of reformed Korean traditional clothing is ordinary dresses. So it should develop various sorts and color, design and textile and be in harmony with international trend. 3) Most of shops handled a coordinate goods like a bag and shoes. 4) In the investigation customers they wanted various colors, high quality in design , logical price and a periodical sale. So four pieces of the reformed Korean traditional costumes were designed and produced based on the present condition.

  • This study deals with the design of snow plow for the special equipment vehicle. The purpose of the study is to develop the snow plow that can install in the special equipment vehicle such as clean up vehicle or dump truck in winter season. To do so, it is designed by 3 sub-assembly - snow shovel, main frame, and hydraulic cylinder and its support. The snow shovel consists of 3 pieces to meet the road profile and to exchange easily the damaged parts. Main frame connects the snow shovel with the hydraulic cylinder and its support and supports the weight of snow. Finally, the hydraulic cylinder and its support move the snow shovel up and down and tilt it. We designed it using 3D commercial CAD software for concurrent engineering design.

  • This study is a structural analysis of 3" Cryogenic Safety Breakaway Coupling using a manufactured product from KLAW Company. Breakaway coupling is very important in the pipe system, especially when transporting fuel or gas in the pipeline. For the analysis of the patent infringement target, Dover and KLAW Company's technologies (US 08127785, EP 0764809) were analyzed. Finally, the flip-flap valve overlap was measured after combining the breakaway coupling through 3D modeling, and the valve overlap had a 0.7mm measurement value from the height gauge. The safety breakaway coupling consisted of a total of 62 pieces (body: 42, valve module: 21).

  • A lot of pieces of iron plate are used to build a ship. The states of cutting surface of iron are however bended or ununiformly cuttled by cutting machine. These may cause bad Quality of painting, and shorter lifetime of iron by rust. In this paper, a new approach of grinding force control method which teaching of robot is not required is proposed to avoid long preparation time of robot and to improve the productivity. The way used in this paper is just like a blind man works through the road with stick only.

  • This study was carried out to Identify wood and charcoal segments, which were excavated in 1994 at the Seohaean highway construction site along the western coast of Korea ; Tuntaeri, Hwasunggun. We identified the objects excavated at the fire places of the Tuntaeri dwelling sites (early Koryo period ; A. D. $11\~12C$) ; charcoal pieces and 1 wood segment, which was used for the handle of a metal hook. Chestnut(Castanea crenata), deciduous oaks(Quercus spp.) and maple(Acer app.) were identified from the charcoals, whereas the wood segment as willow species(Salix spp.). These species seem to represent warm and wet climate in the middlewest Korea during $11\~12C$.
