In order to convey exactly what a work is intended to project, it is necessary to select appropriate materials, those whose features are suitable for the work to be accomplished. Among the recent trends in dyeing involve the use of the designers' own techniques and a variety of materials, as well as the designers' efforts at promoting the value of plastic art. According I choose splendid butterfly patterns that diversity in shape and color, among nature patterns offer unlimited imaginative power. I designed the fabric pattern, using tie dyeing, cone dyeing, transfer dyeing and rub dyeing that can best express my intentions. Therefore a total of four works were designed with aesthetically appealing revised shapes of a butterfly, using materials developed using the same method, to suggest the possibility of creating a new design while maintaining the original beauty of plastic art.

A three-dimensional numerical analysis was carried out on incompressible flows in butterfly valves by using commercial FLUENT/UNS code. Characteristics of complex flows including cavitation effect were investigated for different valve disk angles. The butterfly-valves that had different disk angles and different disk shapes were compared with each other in detail. This study focused on the flow analysis in the conventional butterfly valve and the newly designed butterfly valve in order to prevent cavitation. The newly designed valve shows great improvement on performance and endurance.

These days, by the accelerated developments of science and industries and the menaces of war and terror, humans have come to have instinct to recur and nostalgia to nature and thereby many art works and designs with natural objectives have begun to be produced. Also the design in 21st century requires creative products based on cultural speciality of the countries. As the examples, we may easily find the images of the countries from visual expressions or products when we get in touch with the products of so called advanced countries in design i. e. U.S.A. Japan, Germany, France, Italy, countries of Scandinavian peninsular. This study, in such stream of the times, was to express our culture's own originality on clothing design with butterfly that is one of natural thing as the material but limited the boundary to realistic butterflies in folk drawings of the times of Chosun. As for the technique of expression, used digital textile printing for best expression of the fine lines, realistic shapes and peculiar colors of the butterflies in Chosun folk drawings and used diverse materials as materials for printing for diversity of the designs. Thereby this thesis is purposed to grope the products with superior competitiveness in the world market by presenting the realistic butterflies in Chosun folk drawings as motives with cultural value native to Korea and applying them to clothing designs.

The main objective of this research was to understand the latest trends of natural print design through the quantitative & qualitative analysis of fashion appeared in contemporary female collections. The research criteria was defined as 3 seasons from 2011 S/S to 2012 S/S. Data collection of 726 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency with chi-square test was conducted. Also qualitative interpretation of natural print design' characteristics was completed. The main findings were as follows.; The average occurrence rate of natural print design from 2011SS to 2012 SS in three collections were 6.4% in Milan 6.4%, 5.5% in Paris and 6.8% in N.Y. The five source types of natural prints in contemporary women's fashion collections were identified and the order of their appearance were as follows: flowers, plants, animals, insects & marine organisms and compound one. The plant prints were expressed by stylized or realistic touch. Flower patterns showed more variables than plants, however, there were no big difference in their image and major characteristics. The animal prints demonstrated two aspects. First one used typical animal print of fur or skin, but the other one draw the animal figure like paintings. The compound source type presented the most interesting and fresh pattern design ideas. In the insects & marine organisms, mainly butterfly and seashell & starfish, etc. appeared as real shapes or sometimes were stylized.

An immunohisochemical study on the cerebral ganglion of the African giant snail, Achatina fulica. was conducted by applying the AB/AY staining and the avidin-bovine-peroxidase complex staining methods. The followings are the results obtained throughout the study. The cerebral ganglion of Achatina fulica is an ellipsoidal body of 2 x 1 mm in size, which is connected by the cerebral commissure of 1 mm in diameter. The cross-section through the cerebral ganglion, shaped like a butterfly, is divided into the medio-dorsal parts, the latero-dorsal parts, the caudo-dorsal parts, and the lateral lobes. In the medio-dorsal and latero-dorsal parts, the LG cells and the DG cells are found mixed, although the LG cells are dominant. In lateral lobe, however, the Y cells are quite dominant, while the LG cells and the DG cells are seldom found. The LG cells are 20-70 $\mu\textrm{m}$ in sizes and circular or ellipsoidal in shapes. They are stained light green with the AB/AY. 1 - 3 nucleoli are found in karyolymph, where granular chromantins are evenly distributed. In cytoplasm, it is found that the secretory granules are evenly developed.
