Age And Sex

Between January 1983 and December 1991, 70 patients with RCC underwent radical nephrectomy in the Dept. of Urology of the Ospedale Civile di Sanremo. Survival was evaluated with regard to age and sex of pts., site of the neoplasm (polar or midrenal), side, size, cell pattern, grading and pathologic staging. The statistical significance was studied for each of these data. Data are homogeneous due to use of the same surgical technique (trans or thoracoabdominal access, preliminary ligation and division of renal vessels, removal of the kidney with its peri-renal fat, Gerota's fascia and the ipsilateral adrenal gland, extended lymphadenectomy). All operations were performed by the same surgeon.

Automatic Grading

Although point and line grading are widely utilized in garment CAD system, they have a common disadvantage: the increments of cardinal points or line on the to-be-graded patterns have to be calculated and inputted manually. In previous work, basic and fashion pattern are defined and the constant and proportional relation between them are considered to explore computerized grading. In the research, a dart pivotal-transfer relation between basic and fashion pattern is introduced. This paper proposes an automatic grading approach based on dart pivotal-transfers. This approach is illustrated with an example of the front panel of women’s jacket, the cardinal points concerning a dart are rotated around a pivotal-point, the increments of the cardinal points are transformed from that of original ones, and then the X and Y coordinates of the cardinal points in the to-be-graded pattern are gained. The experimental results show the approach is feasible.

Every so often, grading is not 100% accurate due to the conventional system for calculating the grading incre¬ment. The aim of this study was to develop a new calculation system of grading increment provided by different software, e.g. Lectra, Gerber, Optitex, Boke CAD etc., and to develop a new mathematical solution that enhances grading precision. For this experiment, three different spec sheets of different buyers were collected, and then combined and drawn to a solitary sketch for both front and back including all points of measures (POM) for a more easy comparison. The solutions for the presence of diagonal and curve measurements were provided with examples using various tools and techniques of different professional garment CAD software. The benefit of the new approach is not only reduced errors of grading but also guaranteed garment fit without distorting style features. However, the drawbacks of the measurement method are complicated and time-consuming. They revolve around the fact that iterative fitting and adjustments are mandatory to improve the fit before bulk production. The study revealed that this new system slightly increases calculation time, whereas the sample approval time for order execution reduces considerably.
