The purpose of this study is to characterize physical and tensile properties according to a knitting method as basic materials for solving the difficulties that occur due to the fact that the crosswise elongation is most different among knit stitch at the time of measuring elongation of knitwear. The sample used for this study was wool $100\%$ and was knitted into two, that is, controlled loop length controlled to properties of structure and fixed loop length by using Shimaseiki SES-124S 12G computer automatic flat knitting machine with DSCS device. Also, the density of rib fabric was 12gauge and its quantity was a total of seven of $0{\times}0,\;1{\times}1,\;2{\times}1,\;2{\times}2,\;3{\times}3,\;4{\times}4$ and including plain fabric, and knitted 2 pieces of sample of 300 wale${\times}400$ course. In conclusion, rib stitch has the much higher stretch rate in the direction of the course than other stitches.

An algorithm has been developed to determine changes in surface topography on asperity level. The software stitches small but detailed images together to create one large image. If such an image is made before and after an experiment, their difference shows a direct 3D view of the changes in micro-geometry, rather than a change in surface parameters. The algorithm is described in detail and illustrated using artificial as well as real surfaces.

The position detection of overlapping area in the interframe for image stitching using auto and cross correlation function (ACCF) and compounding one image with the stitching algorithm is presented in this paper. ACCF is used by autocorrelation to the featured area to extract the filter mask in the reference (previous) image and the comparing (current) image is used by crosscorrelation. The stitching is detected by the position of high correlation, and aligns and stitches the image in shifting the current image based on the moving vector. The ACCF technique results in a few computations and simplicity because the filter mask is given by the featuring block, and the position is enabled to detect a bit movement. Input image captured from CMOS is used to be compared with the performance between the ACCF and the window correlation. The results of ACCF show that there is no seam and distortion at the joint parts in the stitched image, and the detection performance of the moving vector is improved to 12% in comparison with the window correlation method.

The purpose of this study was to develop a system by which the tensile properties of knitted fabrics can be applied. In this study, 3 different conditions of tensile property were tested on 8 sample fabrics with various stitches and stretch ranges. The subjects were five women of age from 18 to 24 years showing average body figures. The major findings derived from this investigation were as follows: The tensile properly of 12gf/cm was considered as appropriate for applying into the pattern alteration in the case of moderate stretch(course, $25\~35\%$) or over samples. However, for the stable stretch(course, under $20\%$) fabrics, such as Milano rib stitch, a tensile properly of 20gf/cm was regarded as more valid.

Nowadays, most automotives companies are making use of laser welding in car body assembly shop. But even though laser welding is better than resistance spot welding in many points, its application has been limited to special technology for manufacturing. The paper introduces in the field of remote welding system (RWS) to improve the process efficiency of laser welding. Positioning time of RWS between welding stitches is dramatically reduced to zero. It is a kind of solutions to generalize laser welding in mass production. This RWS consists of fiber laser, industrial robot and 3-axis scanner.

The purpose of this study was to identify the constructive principle and techniques of Vionnet's works. According to analysis of Vionnets works, it was found that Vionnet conceived of the human body as a continuous shaping of a cylinder. Vionnet's drapery denied the planner presumption of woman and gave real three-dimension to form and to fashion. The techniques of Vionnet's works were as fallow : (1) She introduced the diogonal "bias cut" and changed dress design by her sensuous use of fabrics. (2) She eliminated interfacing to keep the silhouette and the fabric soft. (3) She manipulated the fabric to remove the excess for fit and decoration at the same time. (4) She treated the fabric with a synthesis of geometry and grace. (5) The sale luxury allowed was to note the choice of seams, facings, hems, and stitches. (6) Vionnet's dresses were not lined.

Laser welding application for car body manufacturing has many advantages in the stiffness and the lightness of vehicle, the productivity of assembly line, and the degree of freedom in design. This presentation will express the innovation of car body manufacturing including parameter optimization, process modeling, and system integration. In this application the investment for systems was cut down dramatically by real time switching over the laser path between two welding stations. Points of technical discussion are as follows; optimization of parameters such as laser power, robot speed and trajectory, compact and useful design of jig & fixture to assure welding quality for 3 sheet-layer zinc-coated steel, system integration between 4㎾ Nd:YAG laser device and the other systems, on-line real time welding quality monitoring system, perfect safety standards for high power laser, minimization of consumption costs such as arc lamp, protective glass for optic, etc. This application was successfully launched mass production line in 2001. The laser-welded line of side panel consists of 122 stitches totally. And the length is about 2.4m.

Seven patients had undergone repair of endocardial cushion defect from Jan. 1977 to Dec. 1984 at National Medical Center. Most patients had no associated anomalies except one who had PFO, and mortality case was absent. Five patients had partial ECD and two had complete ECD [Rastelli type A]. In P-ECD patients, the atrial septal defect was closed with patch in all cases and mitral cleft was approximated with 2-3 direct stitches. In two cases of C-ECD, atrial and ventricular septal defect was closed with single patch in one case and atrial septal defect was closed with patch but ventricular septal defect was closed with patch but ventricular septal defect was closed it direct suture in the other case. Atrioventricular cleft was approximated with 2-3 direct sutures. Postop. transient A-V block was noted in 2 cases but returned to regular sinus rhythm after 2 to 6 months.

In the 21st century, men is expressing the femininity instead of the muscularity. And a boundary line between a man and a woman is not clear any more. A man is interested in the lifestyle of a woman, and he imitates her fashion styles, hairstyles, accessories, make-up, and plastic surgery. He is called as "Metrosexual" or "Crossexual". Nowadays, men as well as women can satisfy the wants for beauty. The beautiful appearance of a man has a good impact on the social relationships. The feminizing trends are generally accepted and are shown in the silhouettes, details, colors, fabrics and accessories. The feminizing trends in men's knitwear are shown in the various items. They have slim silhouettes and feminine details. Also they are made of bulky yarns or fancy yarns, and various stitches for texture effects. The most outstanding changes in men's knitwear are the vivid colors and flower patterns.

In this study we investigated the shear and forming behavior of chain stitched multi-axial warp knitted fabric preform, so called non-crimp fabric (NCF). The picture frame test was performed to characterize the shear behavior of NCF and also provide material properties for the numerical simulation of its deformation behavior. The forming behavior of NCF with chain stitch were investigated using hemispherical forming tools. The experimental results show that processing conditions such as blank holder force (BHF) and preform shape are crucial to determining the forming behavior of NCF. For instance, an asymmetric formed shape, which is due to the stitches introduced to NCF, turns into a symmetric one as BHF increases. Furthermore the in-plane and out-of buckling (wrinkle), the severance of which were quantified using image processing method, decreases significantly as BHF increases.
