This study examines the relationship between breast shape and brassiere construction through the comparative analysis of brassiere pattern on the breast shape. This researcher drew the brassiere pattern of developing a pre-study for Chinese female adults according to average size based on the four breast shapes. And then we measures brassiere pattern size and comparatively analyzes breast between size and shape. Comparative analysis results of brassiere patterns are verified differences of size and shape on the breast shape. Above all an angle of cup dart showed remarkable differences on the breast shape. An angle of cup dart isn't proportioned to breast size. An angle of cup dart for cone shape is bigger than dome shape. Because cone shape breast is protruded center part but dome shape breast have a shape of smooth curve like a half globe. So an angle of a cone shape breast cup dart is determined bigger than dome shape breast. For increasing the uplift effect of brassiere, brassiere pattern is different on the breast shape. And a brassiere pattern need different drawing methods about the angle of cup dart, breast inner side diameter, slope and so on. This study has an important significance that it established a mechanical relationship of breast shape and brassiere pattern.

To aim at obtaining a correct and fine small pattern by an electron beam lithography several conditions and methods affecting a real pattern shape needs to be investigated. A micro/nano sized pattern shape is sometimes dependent on the scanning method. In this work, four types of scanning methods are implemented and their characteristics are investigated. For a $11\times11um$ pattern, a Zigzag scanning method proves a precise pattern generation. The other ways such as SEM scanning and swirl in-out scanning method result in some distorted pattern shape. It is proved that abrupt change in the pattern generation limits to obtaining a fine and small pattern.

In this study, the subjects are the expression methods and compositions of peony patterns in Chinese textiles. This study represents the peony patterns which are from Tang Dynasty to the Qing Dynasty, the research subjects are the peony patterns in fabric, except the peony patterns which are expressed by gold foil, embroidery and kesi. The objects of this study are 72 pieces of peony patterns. We sketched the configuration details of peony patterns through the Illustrator program. Analyze and classify the configuration accurately. Based on the 72 pieces of peony patterns, expression methods and compositions of the peony pattern are as following, firstly, we classified peony patterns into three categories, based on expression methods, as realistic shape, pattern shape and shape. Among these 72 fabric relics, there most of realistic shape 42 pieces(58.3%), pattern shape 25 pieces(34.7%), and shape 5 pieces(7.0%). Secondly, in the realistic shape peony, the most of pattern has petal accumulate as grape- shaped. This type is found in almost every Dynasty and was used regularly in the eras of Song and Ming Dynasty. In the era of Ming Dynasty, by using petals like the curly mushroom, Yeongji(靈芝), the pattern of symbolizing longevity was habitually used. The U-shaped flower pattern (type E) and the pattern of emphasizing the veins of petals are found only in the remains of the era of Qing Dynasty. Thirdly, in the pattern shaped peony, the most of pattern has some petals which are separated(type C). Fourthly, we classified peony patterns into four categories, based on compositions, as individual branch form, floral branch form, cluster branch form and floral nest form. Among these 72 fabric relics, there most of individual branch form 33 pieces(45.8%), floral branch form 18 pieces(25.0%), cluster branch form 13 pieces(18.1%), floral nest form 8 pieces(11.1%).

In this paper, we propose an efficient two-step pattern matching method which promises shape distortion-tolerant recognition of handwritten of handwritten Hangul syllables. In the first step, nonlinear shape normalization is carried out to compensate for global shape distortions in handwritten characters, then a preliminary classification based on simple pattern matching is performed. In the next step, nonlinear pattern matching which achieves best matching between input and reference pattern is carried out to compensate for local shape distortions, then detailed classification which determines the final result of classification is performed. As the performance of recognition systems based on pattern matching methods is greatly effected by the quality of reference patterns. we construct reference patterns by combining the proposed nonlinear pattern matching method with a well-known averaging techniques. Experimental results reveal that recognition performance is greatly improved by the proposed two-step pattern matching method and the reference pattern construction scheme.

Membrane structures, a kind of lightweight soft structural system, are used for spatial structures. The material property of the membrane has strong axial stiffness, but little bending stiffness. The design procedure of membrane structures are needed to do shape finding, stress-deformation analysis and cutting pattern generation. In shape finding, membrane structures are unstable structures initially. These soft structures need to be introduced initial stresses because of its initial unstable state, and it happens large deformation phenomenon. And also there are highly varied in their size, curvature and material stiffness. So, the approximation inherent in cutting pattern generation methods is quite different. Therefore, in this study, to find the structural shape after large deformation caused by Initial stress, we need the shape analysis considering geometric nonlinear ten And the geodesic line on surface of initial equilibrium shape and the cutting pattern generation using the geodesic line is introduced.

Recently, a hyaluronic acid micro needle patch for therapeutic and cosmetic purposes has been used by attaching directly to the skin with a pattern having a micro needle shape of 1/3 thickness of hair. These products are attracting attention as an innovative product that maximizes the effect by activating the active ingredient in the skin in the deep skin without blocking the horny layer because the micro needle shape exists on the patch surface so that it can penetrate effectively to the skin. Currently, DAB (droplet air blowing) or MEMS technology is used to make pattern shapes for patches. Because of this technology, manufacturing time is long and manufacturing cost is high, so we tried to develop the mold technology to machine the microneedle shape directly to the metal. In this study, we first fabricated a needle pattern with a quadrangular pyramid shape and finally produced a conical needle pattern.

The purpose of this study was to investigate the bodice prototype method suitable for the upper body shape of old-old aged women using the 3D anthropometric data. And it was to provide the basic data for the upper body garments of old-old aged women. In the overall appearance evaluation, the B pattern was rated as 4.00, and it was evaluated as the most suitable for the bodice prototype of the old-old aged woman. The E pattern was rated lower than normal, and the L pattern and the S pattern were found to be inadequate for older female bodice prototypes. As a result of the measurement of the waist and bust air gap of bodice prototype, the air gap of the bust was not significantly different between the patterns. But the waist air gap showed the largest difference between the L pattern and the S pattern. As a result of evaluating the appearance, the amount of space in the state of 3D simulation, and the air gap, the pattern B appeared to be the most appropriate prototype for the old-old aged women's body shape. However, there is a tendency that the shoulder end point is biased toward the back, so it is necessary to set the inclination of the back shoulder line to be more gentle. Conversely, the front shoulder should be more inclined. In the case of the 3D simulation, the B pattern showed that the other parts generally fit well. In the case of the 3D simulation program used in this study, it was evaluated that it is suitable only for the normal body shape because it is impossible to set the isometric angle which is one of the characteristics of the older female body shape. A study on the bodice prototype suitable for the bent body shape should be carried out through experiments on the actual body shape of various elderly women. In order to cope with the increase of elderly people who are familiar with digital, I think it is necessary to develop an avatar that reflects the old female body shape.

The object of this study is shape finding and cutting pattern generation of membrane structures under the following assumptions : (1) material is linearly elastic (2) stress state is plane stress. Cable and membrane structures should introduce the nonlinear analysis considering geometric nonlinearity because these structures deform largely under the external loads. The analysis procedure is consisted of three steps considering geometric nonlinearity unlike any other structures. First step is the shape finding analysis to determine the initial equilibrium shape. Second step is the stress-deformation analysis to investigate the behaviors of structures under various external loads. Once a satisfactory shape has been found, a cutting pattern based on the shape finding analysis may be generated from the view point of construction. In this paper, (1) shape finding analysis formulation and an example, (2) cutting pattern determination procedure using weighted least-square minimization flattening method and some results are presented.
