  • The inspection unit which is developed and used in this study, is processed the shape data from the CCD camera to seek welding bite section shape, and then calculated as a real dimension from measuring the value of each inspection item. The reason of measuring with the real in this study is came out from the image method which used for a long time, which is extricated the characteristic as the dimension of pixel by recognize pixel. The measurement method of the section shape is that we decide the thresholding value after we drew the histogram to binarizate the object. After that, we make flat the object to get rid of the noise and measure the shape of welded part through the boundarization of the object. The shape measurement is that measure the value of the welding part to adapt the actual operation program from using the ratio between the actual dimension of the standard specimen and the dimension of image, to measure the ratio between the actual product and the camera image. The inspection algorithm which estimates the quality of welded product is developed and also, the software GUI(Graphic User Interface) which processes the automatic test function of the inspection system is developed. We make the foundation of the inspection automatic system and we will help to apply other welding machine.

  • The purpose of this study is to investigate the symbolic meaning in body image and fashion style portrayed in Korea and American movies in aspects of sex, race, nature, and technology. The researcher analyzed movies in Korea and USA, and the results were as follows. In aspects of sex, movies portrayed new masculinity and femininity escaped from previous gender stereotypes, and the clothing styles characterized sex identity and sex roles. In aspects of race, more various races appeared in America movies than Korea's, and the appearance and stereotypes related with race were blurred by the globalization and the change of film market environments. In aspects of nature, Korea movie portrayed the human being as lyrical appearance in nature, and America movie expressed the human as a strong men conquering the nature in adventure movie or super human image combined with nature thing which endowed nature's superior characteristics to human body in fantasy and science fiction movies. In aspects of technology, the human bodies were described as cyborg, alien, or super human, which symbolized the do-identification in digital world, de-boundarization between human and machines, and the human's uncertainty.
