The principal purpose of this study is focused on the fabrics used in Kaya period by investigating the imprinted fabrics on the remains of the old tomb of Dohang-ri and Jeesan-dong which were built around the late 4th century to the late 6th century. Most of the remains are plain weaved, however there is one remain that 4-end complex gauze with patterned, and the other is weaved with geometrical pattern which were plain weave with 2 · 1 twill and 3 · 1 twill. The imprinted fabrics that had twists had S twists only. Of all the fabrics that were examined, the most loose one had the density of 8 × 6/cm, the most fine fabric had the weft density of 91.8 strands/cm and the warp density cannot be counted. It is No. 416 of Doharg-ri tomb that has the highest ratio of density as 3.15. All the fabrics observed by SEM and Polarizing Microscope are hemp.

The purpose of this study is to develop a new method for the visual presentation of weaves and woven patterns of dobby fabrics by using the personal computer briefly. The following results were given through adapting this method to the design for patterns of woven fabrics. 1. Complete weaves were given by computerizing the pegging plan and drafting system. 2. The effect of the combined woven patterns were given by computerizing the one complete weaves, the differently coloured warp threads, and the differently coloured weft threads.

In this study, PET fabric was hydrolyzed with NaOH using the Tank m/c and Liquor-flow m/c to determine the alkali hydrolysis properties of PET fabrics. The results were as follows ： The weft density and tensile strength of PET fabrics hydrolyzed with Liquor-flow m/c were higher than those hydrolyzed with Tank m/c in case of less than 10％ of weight loss. However, above 10％ of weight loss, reverse phenomenon was showed. K/S value of hydrolyzed PET with Liquor-flow m/c was higher than that with Tank m/c above 10％ of weight loss. It was observed that the micropores of PET surface were collapsed due to physical force(abrasion and collision) during hydrolysis. Bending rigidity of hydrolyzed PET fabric was about 32％ and 40％ of bending rigidity of warp and weft direction of untreated fabric at 7％ of weight loss, respectively. Above 7％ of weight loss, decrease rate was decreased.

A direct tilted-ring fitting method allows us to investigate kinematic structure of spiral galaxies. By employing the method to high-resolution HI data cubes, we can more easily trace warp characteristics of spiral galaxies than ever. In this contribution, we make use of TiRiFiC to VLA HI data cube of spiral galaxies in Virgo cluster, and present our preliminary yet interesting results. The TiRiFiC (Tilted-Ring-Fitting-Code) is publicly available code that provides 'best-fit' tilted-ring parameters (i.e. position angle and inclination) via chi-square minimization technique. We also discuss possible biases (e.g., resolution dependency) and its effect on our conclusions.

This essay examines the costumes for gods and priests in ancient Mesopotamia as they are depicted in various documents and artifacts of the period, and it is part of an ongoing project that studies the process in which the religious costumes, the means of religious communication, of ancient Mesopotamia had evolved. The study shows that the religious costunmes in ancient Mesopotamia have following characteristics. 1. The costumes for gods are the same as those for men, including warp-around skirts, tierd skirts, shawls, and tunics. However, there are some differences : costumes for gods include such distinguishing features as aprons and long tassels. 2. Both wear stylized headpieces that indicate their divinity and have long hair and long beard. 3. As for shoes, the Sumerian and Babilonian gods go barefoot, but the militant Assyrian gods wear sandals. 4. Sumerian and Babilonian figures do not have much, but the Assyrian gods wear various ornaments including earrings and bracelets that emphasize their muscular physique. 5. Priests wear weird skirts or wrap-around skirts but no top. They have shaved hair to indicate their role as purifiers, but some of them have long beards.

Stress analysis was conducted with finite element method to study the stress distributions in both single-pin and multi-pin loaded composite laminates. The various parameters involved in the design of the joint method were considered. The stress distributions in the vicinity of the holes were predicted considering the effects of various parameters such as the lay-ups, number of pins, number of rows, row spacing, and hole patterns. The results show that the performance of joint is greatly affected by these parameters.

This paper is to analyze patterns for Indonesian traditional textiles. Ikat is the resist-dyeing process in which designs are reserved in warp or weft yams by tying off small bundles of threads with fiber resists to prevent the penetration of dye. Batik is the technique applying a wax resist before dyeing to form a pattern in negative. Ikat and batik are the most renowned textile arts of Indonesia. Patterns are classified as geometric pattern, plant pattern, animal pattern. Also this paper discusses the origins of ikat and batik. Therefore this Paper proposes the classification and feature extraction of ikat and batik patterns. The results of this study can be effectively applied to develop competitive pattern design for Indonesian textile market.

In this paper, we present a 3D reconstruction method of color volume data or a computerized human atlas. Binary volume rendering which takes the advantages of shear-warp factorization and new normal vector calculation method visualizes 3D organs in real time. Various manipulations such as rotation, multiple object rendering, removal, and transparency effect improve the usefulness and comprehensiveness of the computerized atlas.

With recent trends leaning towards product miniaturization, the advent of new material and speedy delivery times, old style conventional trial-and-error methods have been only serving to weaken corporate competitiveness. Reliant on tiny increments of time-consuming experience, this antiquated approach begets a delayed delivery of product development, cost loss and quality depreciation. To solve such problems, the Dedicated Injection Molding CAPA (Computer Aided Plastics Application) performs a preliminary examination on problems rising from every stage of creation - from appropriate material selection and mold design to mass production - through a computer system. Thus, it determines the optimum design variables and process conditions while diagnosing and solving defective molds.
