The Information of Edges which takes small area comparing with the total image is very important in DNA images as well as general images. DNA image is the object should be managed by computing and it's demanding information is less than general images, but the accuracy is more important In a huge DNA image processing system such as DNA Information Bank, the performance depends on the size of image. In this paper, we extract the edge information and make it as a binary image. To reduce the size of the original image, it was applied by JPEG image compression method. The compressed image is combined with edge information when they are restored. As a result, Both the image compression ratio and restoration quality are optimized without the loss of critical information.

In this paper, we propose an efficient algorithm for mapping a $360^{\circ}$ circular image to a planar image. The proposed algorithm consists of obtaining size of the planar image, calculating the distance between the camera and the planar image, calculating horizontal angle of camera and planar image, calculating vertical angle between camera and planar image, calculating the position of a pixel that matches pixels in a $360^{\circ}$ circular image to pixels in a planar image. Experiments were performed to evaluate the efficient algorithm for mapping the proposed $360^{\circ}$ circular image to the plane image. The reconstruction rate of the mapped plane image was confirmed 99% and the image quality of the mapped plane image was confirmed 72%. Since the results were higher than the standard values of commercial software, the effectiveness of the algorithm was confirmed.

The purpose of this study was to examine the influence of aesthetic surgery attitude, self-esteem and body image on clothing behavior. Subjects were 356 female college students in Seoul. The data obtained were analyzed by reliability analysis, factor analysis, correlation analysis, stepwise multiple regression analysis and t-test. The major results of this study were as follows: First, five factors of aesthetic surgery attitude were identified: risk tolerance of aesthetic surgery, need of aesthetic surgery, image improvement via aesthetic surgery, keeping the secret of aesthetic surgery, and others' expectation of aesthetic surgery. Second, significant relationships were found between body image and clothing behavior, and self-esteem and body-enhancement of clothing. Also, risk tolerance of aesthetic surgery, need of aesthetic surgery, and image improvement via aesthetic surgery had a significant correlation with clothing behavior. Third, the most important variable which affected the aesthetics and body-enhancement of clothing was body image. The entertainer imitation behavior of clothing was influenced by need of aesthetic surgery, body image, keeping the secret of aesthetic surgery, risk tolerance of aesthetic surgery, and image improvement via aesthetic surgery. Preference for luxury goods of clothing was influenced by need of aesthetic surgery and body image. Body-enhancement of clothing was influenced by body image, image improvement via aesthetic surgery, and self-esteem.

The purpose of this study was to examine the image of dental hygienists. The subjects in the study were 396 patients and their caregivers who visited 14 dental hospitals and dentists' offices in and around Seoul. After a survey was conducted, the following findings were given: 1. The people investigated gave a mean of 4.0 to the image of dental hygienists. Dental hygienists rated highest in terms of looking neat and tidy(4.33), and were given the lowest marks in arbitrary job performance(3.46). 2. There appeared four different types of dental hygienist images, which made a 59.824 prediction of the image of dental hygienists in general. A typical image(4.11) was most dominant, followed by professional one(4.07), personal one(4.01) and social one(3.73). 3. The relations between the general characteristics of the respondents and their image of dental hygienists could be described as below: 1) By age, those who were in their 60s(4.12) had the best image of dental hygienists, and the teenagers(3.90) had the worst image of them. 2) By gender, the men(4.05) looked at dental hygienists more positively than the women(3.96). They had a significantly different opinion on the social image of dental hygienists according to gender(pE0.05). 3) By marital status, the married people(4.00) had a better image of dental hygienists than the unmarried ones(3.95). 4) As for the influence of the type of dental institutions, they had a more favorable image of dental hygienists in dentists' offices(4.13) than in dental hospitals(3.88). There was a broad significant difference in the way they looked at the professional and personal images of dental hygienists according to the type of dental institutions(pE0.001). 5) As to the impact of educational level, those who received community-college or higher education(4.01) had the best image of dental hygienists, and those who received middle-school or lower education(3.91) had the worst image of them. 6) By occupation, the government workers and students(4.07) had the best image of dental hygienists, and the company employees(3.90) had the worst image of them. They took a significantly different view of the social image of dental hygienists according to occupation(pE0.05). 7) Concerning the impact of the frequency of receiving dental treatment, the respondents who had received it seven times or more(4.16) had the best image of dental hygienists, and those who hadn't(3.79) the worst image of them. There was a wide significant gap according to that frequency. The way they looked at the typical, social and professional images of dental hygienists was quite different significantly according to that frequency as well(pE0.001). 8) As for the influence of whether they were accompanied by caregivers or not, the people who weren't accompanied by caregivers(3.99) had a better image of dental hygienists than those who were(3.97).

In Shamir's (t,n)-threshold based secret image sharing schemes, there exists a problem that the secret image can be reconstructed when an arbitrary attacker becomes aware of t secret image pieces, or t participants are malicious collusion. It is because that utilizes linear combination polynomial arithmetic operation. In order to overcome the problem, we propose a secret image sharing scheme using matrix decomposition and adversary structure. In the proposed scheme, there is no reconstruction of the secret image even when an arbitrary attacker become aware of t secret image pieces. Also, we utilize a simple matrix decomposition operation in order to improve the security of the secret image. In experiments, we show that performances of embedding capacity and image distortion ratio of the proposed scheme are superior to previous schemes.

Korean textile industry is faced a turning point, And the culture of a country itself is getting a main competetive items. Therefore, this study is focused upon developing fashion items of Korean image. For this study purpose, I carried out literature review and questionnaires were surveyed with 129 women, to see how Korean women interested in costume are conscious of Korean image and the way to develop Korean image fashion items. The study results are as follows. 1. To Koreans, the elements of Korean image were Hanbok(Korean traditional cloths) and Saeckdong(traditional multi-coloured stripes), but to foreigners they were national image. 2. To develop competetive fashion items of Korean image, I recommend as follows. - set up a typical key-word of Korean image - promote top designer - globalization of Hanbok - take advantage of 2002 Wold Cup - bring Korean image fashion into vogue to the younger from domestic to abroad - make Korean image into universal fashion - start with accessories, hats, bags, scarves

We have developed a 3-D image processing and display technique that include image resampling, modification of MIP, and fusion of MIP image and volumetric rendered image. This technique facilitates the visualization of the three-dimensional spatial relationship between vasculature and surrounding organs by overlapping the MIP image on the volumetric rendered image of the organ. We applied this technique to a MR brain image data to produce an MRI angiogram that is overlapped with 3-D volume rendered image of brain. MIP technique was used to visualize the vasculature of brain, and volume rendering was used to visualize the other structures of brain. The two images are fused after adjustment of contrast and brightness levels of each image in such a way that both the vasculature and brain structure are well visualized either by selecting the maximum value of each image or by assigning different color table to each image. The resultant image with this technique visualizes both the brain structure and vasculature simultaneously, allowing the physicians to inspect their relationship more easily. The presented technique will be useful for surgical planning for neurosurgery.

The digital images contain a significant amount of redundancy and require a large amount of data for their storage and transmission. Therefore, the image compression is necessary to treat digital images efficiently. The goal of image compression is to reduce the number of bits required for their representation. The image compression can reduce the size of image data using contractive mapping of original image. Among the compression methods, the mapping is affine transformation to find the block(called range block) which is the most similar to the original image. In this paper, we applied the neural network(SOM) in encoding. In order to improve the performance of image compression, we intend to reduce the similarities and unnecesaries comparing with the originals in the codebook. In standard image coding, the affine transform is performed with eight isometries that used to approximate domain blocks to range blocks.

This paper outlines the development of image processing system, which will allow the general users in Government and Public organizations easily to use and apply KOMPSAT EOC images in their own business. The system includes an import/export module of EOC image distributed in Hierarchical Data Format (HDF) file and various image processing analysis modules. Especially, the image mosaic and subset functions are designed to use EOC image as an image map, generating the Ortho-image module. To update the various spatial data with EOC image, some essential modules such as change detection by pattern recognition, overlay between images and vector data, and modification of vector data are implemented in the system. The system is developed based on the user request analysis of government agency, and suited for more efficient use of satellite image in public applications. Such system is expected to contribute to practical application of KOMPSAT-2 that will be launched in 2005. Further efforts will be made to accommodate the KOMPSAT -2 MSC data.

The purpose of this study was to clarify the meanings of the images of the body-in-pieces in fashion design. This study focusing on the body-in-pieces based theoretically in that, and started to figure out the meanings in western art history. Body-in-pieces images were brought in art to express symbolic meanings to destroy the past, sexual fetish, unconsciousness, desire, fantasy, and to disorganize male-subjective idealistic female image. While in fashion design, body-in-pieces images categorized in three, erotic image, cyborg image, abjection image. First, erotic images in fashion design are fragmented body image, such like lip, hair, eye and etc. Second, cyborg image was represented by 3-dimentional molding image made of metallic materials, and last, abjection image representing death image used skeleton and bone image induced uncanny and sadistic feelings. Body-in-pieces images in fashion design are related to fetishism, uncanny, disorganizing traditional femininity.
