In this thesis which takes fashion advertising that functions a marketing communication as an objective, I try to bear witness to the signifying system of garments though analyzing with semiotic methodology the signifying procedure on the base of the structural concept of Ferdinand de Saussure and the advertisement semiotic theory of Roland Barthes, to make clear their signifying structure and it meaning by understanding the characteristics of contemporary society and its cognitive system. Each sign of fashion advertising transfers the brand image through syntagmatic signification which contains the mythology of goods. Mannish style is encoded as tailored jacket, white shirt, H-silhouette and pants, non-color or being color, and it is presented as a clothing sign of casual wear for career women. Feminine style is encoded as X-silhouette, soutien collar suit style, various colors, and other details with womanly image, and it is presented as a clothing sign for maid or young wife 20\`s or 30\`s. Formal style is encoded as jacket vest, inner wear(blouse), two and three piece dress by pants or skirt and one-piece dress, and it is used in every age and class. Casual style is similar to formal style, but differs only in textile code. Clothing sign for housewives in middle age is encoded as H-silhouette of formal style, long jacket and pants and brown, being and grey colors. Contemporary popular phenomena in the signification of fashion advertising, and its temporal ideology reflected are as follows; According to the context of fashion advertising in the middle of 1990\`s, its fashion is that first, military look applied from the designs of various sort of military uniform and vest look and pant style applied from dandy-style imitated from man\`s wear are popuar. This mean that it reflects the change of point of view on woman\`s role in society today. That is, due to the equality between man and woman, it mirrors the ideology of feminism, and then, describes beautifully professional woman with carrer. Second, because that individualism is underlied for the change of consumer\`s consciousness, standardized popularity is disappeared, and in accordance with the mixture of various trends and personalities proposed every season, layered look that emphasizes individualism, easiness and naturalness is popular.

Objective: To assess the effects of iterative model reconstruction (IMR) on image quality for demonstrating non-calcific high-risk plaque characteristics of coronary arteries. Materials and Methods: This study included 66 patients (53 men and 13 women; aged 39-76 years; mean age, 55 ± 13 years) having single-vessel disease with predominantly non-calcified plaques evaluated using prospective electrocardiogram-gated 256-slice CT angiography. Paired image sets were created using two types of reconstruction: hybrid iterative reconstruction (HIR) and IMR. Plaque characteristics were compared using the two algorithms. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of the images and the CNR between the plaque and adjacent adipose tissue were also compared between the two reformatted methods. Results: Seventy-seven predominantly non-calcified plaques were detected. Forty plaques showed napkin-ring sign with the IMR reformatted method, while nineteen plaques demonstrated napkin-ring sign with HIR. There was no statistically significant difference in the presentation of positive remodeling, low attenuation plaque, and spotty calcification between the HIR and IMR reconstructed methods (all p > 0.5); however, there was a statistically significant difference in the ability to discern the napkin-ring sign between the two algorithms (χ² = 12.12, p < 0.001). The image noise of IMR was lower than that of HIR (10 ± 2 HU versus 12 ± 2 HU; p < 0.01), and the SNR and CNR of the images and the CNR between plaques and surrounding adipose tissues on IMR were better than those on HIR (p < 0.01). Conclusion: IMR can significantly improve image quality compared with HIR for the demonstration of coronary artery and atherosclerotic plaques using a 256-slice CT.

In this paper, an iterative restoration algorithm from power spectral density with 1 bit sign information of real part of two dimensional Fourier transform of image corrupted by additive white Gaussian noise is proposed. This method is a modified version of image reconstruction algorithm from power spectral density. From the results of computer simulation with original 32 gray level imgae of 64x64 pixels, we can find that restorated image after each iteration converge to original image very fast, and SNR gain be at least 8[dB] after 10th iteration for corrupted image with additive white Gaussian noise.

For future autonomous cars, it is necessary to recognize various surrounding environments such as lanes, traffic lights, and vehicles. This paper presents a method of speed sign recognition from a single image in automatic driving assistance systems. The detection step with the proposed method emphasizes the color attributes in modified YUV color space because speed sign area is affected by color. The proposed method is further improved by extracting the digits from the highlighted circle region. A sequential cascade AdaBoost classifier is then used in the recognition step for real-time processing. Experimental results show the performance of the proposed algorithm is superior to that of conventional algorithms for various speed signs and real-world conditions.

In this paper, we implemented a sign language communication system between korean and japanese using 3D model. Unitl now, we have developed the system through 2D image. The system, however, has some drawbacks base don the limitations of 2D model. Especially it is not comprehensive in the sign language gesture including forward or backward movements becasue it can only display a front view. Therefore, we employed a 3D model for the representation of sign language. The proposed communication system si implemented with windows 95 visual C++ 5.0 imported open inventor library on pentium 233 system. Experimented results show that the 3D system can solve the problems in 2D representation.

Recognition of traffic signs helps an unmanned ground vehicle to decide its behavior correctly, and it can reduce traffic accidents. However, low cost traffic sign recognition using a vision sensor is very difficult because the signs are exposed to various illumination conditions. This paper proposes a new approach to solve this problem using an illuminometer which detects the intensity of illumination. Using the intensity of illumination, the recognizer adjusts the parameters for image processing. Therefore, we can reduce the loss of information such as the shape and color of traffic signs. Experimental results show that the proposed method is able to improve the performance of traffic sign recognition in various weather and lighting conditions.
