This study aimed to suggest more appropriate and accurate festival costumes based on a comparative analysis on various reproduced costumes and a period review of traditional festival costumes. In particular, the comparative analysis examined festival costumes which appeared in Korean and Japanese festival parades during the Baekje Period. The Baekje Cultural and Sacheonwangsawasso Festivals were examined. A literature review as well as field research and digital restorative techniques were used in the study. The reproduction patterns of Baekje costumes from both festivals were compared with original Baekje costumes, demonstrating several differences in the configuration, material, color, and shape of the costumes in addition to the way they were worn. Based on the comparative analysis, Baekje costumes used in Festivals were grouped into three categories: King's Costume, Queen's Costume, and Government Official's Costume. Dress sketches and 3D illustrations also have been presented.

The main objective of this study was to clarify the taxonomic status and the speciation mechanism of Viola albida complex in Korea. The complex includes three very closely related taxa, taxonomic ranks of which are much in dispute. These taxa in the complex are sympatric in distribution, and they are very similar in most morphological characteristics. Comparative morphological analyses revealed that they can be distinguished on the basis of leaf shape, although they show complicated patterns of variation in leaf shape. The variation of leaf shape in each taxon appeared to be maintained through developmental process, and extensive cleistogamy and vegetative reproduction in these taxa are suggested as the mechanisms maintaining the variation. Genetic variation in this complex was monomorphic in all 14 loci examined. Palynological study also showed that these taxa have the same pollen morphology. These results strongly suggested that they should be recognized as varieties of V. albida; var, albida, var. chaerophylloides, and var. takahashii. The results also suggested that some individuals that can be assigned to var. takahashii might be hybrids between var. albida and var. chaerophylloides.

A new approach to die shape optimal design in extrusion is presented. The approach consists of a FEM analysis model to predict the value of the objective function a design model to relate the die profile with the design variables and a genetic algorithm based optimaization procedure. The approach was described in detail with emphasis on our modified micro genetic algorithm. Comparison with theoretical solutions was made to examine the validity of the predicted optimal die shapes. The approach was then applied to revealing the optimal die shapes with regard to various objective functions including those for which the design sensitivities can not be deter-mined analytically.

The plastic arts is used when designers draw inspirations to create fashion design. The author referred to fashion magazines for designing ideas of Mondrian＇s geometrical abstract painting in practical applications used by designers in Paris, Italy, London and New York during the 10-year period(1991-2000). The collections of data were analyzed as following: ◇ Fashion Designing Idea 1. Matching Idea The art is reproduced in the design as how it is with no transformation. First, the painting＇s complete figure is reproduced on the entire or parts of clothing. Second, the painting＇s partial figure is reproduced on the entire or parts of clothing. 2. Contrasting Ideas The composition elements in Mondrian＇s geometrical abstract painting, for example, structures of shapes, vertical and horizontal lines and different colors are applied in the design. First, one particular shape in painting is transformed into different shape of square, circle or triangle and reproduced in designing. Second, one particular shape in painting is disassembled and then reshaped into different form in reproduction. Third, additional lines are put in to create different look from the original painting. Forth, existing lines are extended over the boundary to create different look from the original painting. Fifth, achromatic colors: black and white, and three basic colors: red, blue and yellow in the original painting are modified into different shades or color scheme is increased in broad range.

Testes from the drake and the gander have been examined by the electron microscopy in thin sections in order to examine the spermiogenesis and the structure of spermatozoa. The spermiogenesis can be divided into three stages: early spermatid, nuclear elongation, and matured spermatid. In the early spermatid of the drake, there are thread-like material in the nucleus, a prominent nuclear envelope around the nucleus, and big lumens in the cytoplasm. The shape of the gander's mitochondria in the early spermatid is slender compared to that of the drake, and the inner membrane of the mitochondria is thicker than the outer membrane. The distal centriole of the drake and the gander in the early spermatid is a long hollow cylinder form. In the nuclear elongation stage, elongated nucleus forms two or three cross sections in one spermatid cell and it is surrounded by the amorphous sheath. The nucleus of the matured spermatid is compact and its apical end is covered with acrosome cap and acrosome spine. The axoneme is surrounded by the amorphous material.

In order to investigate the spermiogenesis of the Korean goat, the tissue obtained from the testis and the epididymis of eight matured bucks were conventionary prepared as thin sections and these sections were observed under a transmission electron microscope. Based on the development of the varous permanent organelles and certain transient structures, the spermiogenesis of the Korean goat could be divided into four main phases: Golgi, cap, acrosome and maturation; and these phases had been further subdivided into a total of nine stages. There was abundance of the contents of acrosomal vesicle contained ring-shaped material surrounding the acrosome in the early cap stage. The mitochondria made the mitochondrial sheath started from the annulus towarding the neck and formed helical arrangement in the mid maturation stage, The postacrosomal denselamina was a, pp.ared to be wave-shape in the late maturation stage. The spermiogenesis of the Korean goat was found to be basically similar to that of the Korean cattle.

In the apparel industry, the technology has been advanced rapidly. The use of 3D scanning systems fur the capture and measurement of human body is becoming common place. Three dimensional digital image can be used for design, inspection, reproduction of physical objects. The purpose of this study is to develop a method that drafts men's basic bodice pattern from scanned 3D body surface shape data. In order to pursue this purpose the researchers developed pattern drafting algorithm. The 3D scanner used in this study was Cyberware Whole Body Scanner WB-4. The bodice pattern drafting algorithm from 3D body surface shape data developed in this study is as follows. First, convert geometric 3D body surface data to 3D polygonal mesh data. Second, develop algorithm to lay out 3D polygonal patches onto a plane using Auto Lisp program. The polygon meshes are coplanar, and the individual mesh is continuously in contact with next one The bodice front surface shape data in polygonal patches form was lined up in bust and waist levels. The back bodice was drafted by lining up the polygonal mesh in scapula, chest, and waist levels. in the drafts, gaps between polygons were formed into the darts.

To study the function and structure of Golgi apparatus in the spermiogenesis of long-fingered bat (Miniopterus schreibersi fuliginosus), the testis obtained from adult bat was treated with the prolonged osmification or fixed with ferrocyanide reduced osmium. golgi apparatus was oval shape in early Golgi phase, and was composed of cortex and medullar enclosing acrosome in mid Golgi phase. The vesicles of crescent shape Golgi apparatus were closed or fused with small or large vesicles at the periphery of acrosome. Golgi apparatus moved behing the acrosome face in cap phase, but the Golgi apparatus was still active. According to this, Golgi apparatus appears to be involved in the formation of acrosome and sperm tail. Transfer of materials from Golgi to acrosme seems to be carried out not only by fusion of large vesicles with acrosomal vesicles but also by detachment of coated vesicle from various cisternae of Golgi fusing with acrosomal vesicle.

The most research on facility layout problems ignored the actual shapes of activity spaces and the aisles between activities. In many cases, the research also ignored the actual shape of building where the activities are to be arranged. In this paper, We present a block based layout technique that applies a genetic algorithm to search for a very good facility layout with horizontal aisles. From the extensive experiments for two different cases with respect to the shape of activity space, it was found that the proposed method generated better layouts than the ones obtained by applying Tam's algorithm in all test problems. The proposed algorithm showed about 10% improvement of performance on the average. We determined the best combination of the reproduction rule and the genetic operators with their probabilities for each test problem through the experiment.
