Printing process has been a major sector in the textile industries for a long period of time. With the advent of digital textile printing, the complex procedures of printing preparations and after-treatment processes have been streamlined. For the design of the motives of images to be printed, the use of image handling software, e.g. Photoshop(Adobe), has been of prime importance. Even though the software is extremely useful and functionally versatile, there are many laborious steps involved for the specific textile printing process. The use of a CAD-based textile printing function may help the textile printing process in streamlining the complex processing stages. The image qualities of the output designs have been compared objectively with the aid of several image similarity evaluation schemes including the SSIM, and FSIM Index methods.

Objectives. The purpose of this study was to compare the shade changes in wet and dry conditions of natural teeth using two different intra-oral colorimeters. Materials and methods. Twenty volunteer subjects have no restorations and fillings in the maxillary central incisors were involved in this clinical study. The color of tooth was measured by two different instruments that were a Shade $Scan^{TM}$ System and a VITA $Easyshade^{(R)}$, Five times consecutive measurements were done for each subject with both instruments. Groups of measurement are an initial wet condition as control, dry in 5 minutes, 15 seconds after re-wetting with saliva, re-wetting after 5minutes and re-wetting after 30 minutes. Using ShadeScan $System^{TM}$, tooth image was captured and converted to the mapping image of Vitapan 3D master. Three main shades were chosen from each subject and calculated the area in Global Lab Image software. Data were analyzed using paired T-Test and Wilcoxon Signed Ranked Test. Using VITA $Easyshade^{(R)}$, color differences($\Delta$E) between measurements were analyzed with one sample T-test. Results. Using ShadeScan $System^{TM}$, there were significant differences between control group and dry(P=.023), dry and re-wetting 15 seconds, 5 minutes, 30 minutes as well(P=.021, P=.017, P=.030) in comparison of primary shade. However, comparing three main shades, there was no significant difference between control and dry(P=.105). Using VITA $Easyshade^{(R)}$, color differences($\Delta$E) between control and dry, dry and re-wetting 30 minutes were statistically different(P=.002, P=.022). Conclusion. Primary shade could be changed in dry and wetting procedure in time, however there was no significant shade changes in overall.

It has been suggested that the endoscopic color of intramucosal gastric carcinoma is correlated with mucosal vascularity within the carcinomatous tissue. The development of electronic endoscopy has made it possible to quantitatively measure the mucosal hemoglobin volume, using a hemoglobin index. The aim of this study was to make a software program to calculate the hemoglobin index (IHb) and then investigate whether the mucosal IHb determined from the electronic endoscopic data is a useful marker for evaluating the color of intramucosal gastric carcinoma, in particular with regard to its value for discriminating between the histologic type. The mean values of IHb for the carcinoma (IHb-C) and the mean values of IHb for the surrounding non-cancerous mucosa ( IHb-N) were calculated in 75 intestinal-type and 34 diffuse-type gastric carcinomas. Then, we analyzed the ratio of the IHb-C to IHb-N. The mean IHb-C/IHb-N ratio in the intestinal-type carcinoma group was higher than that in the diffuse-type carcinoma group ($1.28{\pm}0.19$ vs. $0.81{\pm}0.18$, respectively, p<0.001). When the cut-off point of the C/N ratio was set at 1.00, the accuracy rate, the sensitivity, the specificity, and the positive and negative predictive values of a C/N ratio below 1.00 for the differential diagnosis of diffuse-type carcinoma from intestinal-type carcinoma were $94.5\%$, $94.1\%$, $94.7\%$, $88.9\%$ and $97.3\%$, respectively. IHb is useful for quantitative measurement of the endoscopic color in intramucosal gastric carcinoma and the IHb-C/IHb-N ratio would be helpful in distinguishing diffuse-type carcinoma from intestinal -type carcinoma.

Black has played a more important role in the history of fashion than other colors. In general, black was regarded as a color of negative images. However, as people have recognized the aesthetic value of black color, they have expressed unique and various images of black through the medium of clothes. This study was based on both theory research and actual survey, where survey sheets were distributed to collect data. For data analysis, SPSS 10.0, a statistics software, was used, and frequency, pecentage, t-test, ANOVA test, and Duncan test were adopted and analyzed. The survey was conducted on 608 men over 20 in Seoul, Gyeonggi Province, Gangwon Province, and other areas for two months from May 20, 2005 to July 25, 2005. The analysis showed the following results. First, Dignity was the mostly cited image of black color among men followed by modernity, sorrow, feminineness, abstinence, and sensuality. Second, Men showed different responses according to their age. In sum, men more strongly recognize abstinence and sensuality in black dress as they become older. Marital status significantly affected men's recognition of black dress in terms of abstinence and sensuality. Abstinence was more strongly recognized by married men than single men. In addition, married men pointed out sensuality of black dress more frequently than single men. In short, married men tended to recognize abstinence and sensuality more easily than single men. Education level clearly affected men's recognition of dignity, modernity, and abstinence in black dress. In sum, as men got higher education, they tended to increasingly recognize dignity and modernity in black dress. In conclusion, this study has proved that black dress has unique aesthetic values and reflects various images according to age, marital status, education level.

본 논문은 컬러 역하프토닝에서 참조표에 기반을 둔 벡터적응필터 방법을 제안한다. 역하프토닝은 하프톤영상을 연속계조 영상으로 변환한다. 참조표를 사용하는 방법에는 템플레이트와 학습영상이 필요하며 샘플 하프톤영상과 원영상내의 분포된 패턴으로부터 참조표를 구할 수 있다. 일반적으로 참조표에 기반한 방법들이 다른 방법에 비하여 처리가 빠르며 PSNR면에서도 더 좋은 성능을 보이지만 처리과정에서 참조표에 존재하지 않는 패턴을 어떻게 처리 하느냐에 따라서 많은 품질의 변화를 보인다. 이 논문에서는 이와 같이 존재하지 않는 패턴을 보상하기 위하여 벡터적응필터를 제안 하였는데, 이 방법은 처리하는 픽셀의 주변 화소의 색상, 색농도, 자기 등의 정보를 이용함으로써 컬러 역하프토닝에서 더 좋은 품질을 얻을 수 있다. 제안된 벡터적응 필터 방법이 기존의 최량선형추정에 의한 방법보다 PSNR면에서 더 좋은 결과를 얻을 수 있음을 실험결과에서 알 수 있었다. 참조표의 템플레이트 크기가 커질수록 제안한 방법이 더 좋은 결과를 얻을 수 있다.

The purpose of this study is to apply 3D computer graphics in fashion design as a creative medium and it attempts to fine out what advantages 3D technique can offer to fashion design. For this purpose, this study, first, tries to develop a 3D digital model in which designer can select design, color , pattern and fabric palette whatever necessary . This study uses of the software named 'Poser of Fractal Design' and the and the 3D digital model comprises four stages ; body modeling, item design (item coordination), color design (color coordination), pattern and fabric design (pattern and fabric coordination). Secondly, this study seeks to accumulate a data base which was produced in the course of case studies, which have applied 3D digital model to design. The outcome of the case studies shows that 3D digital model can enhance designing in the following four aspects. ⅰ) It can give more freedom to designer to try various ideas, revise and modify them, It can also produce random generation. Through this process, the designer test various input and output without damage on fabric after revision and alteration. ⅱ) It can help designers to enhance their accuracy. Since fault in the design developed by the 3D digital model can be detected in advance, designers can make correlation before actual work begins. In the end, designers can express their ideas and intention accurately as well as freely. ⅲ) Since design developed by the 3D digital model can be shared on screen by various actors in the course of priduction such designers , merchandisers, and supervisors, it can help communication between and cut the time of feedback.ⅳ) By using the 3D digital model, designers can work from the begining with awareness of actual outcome their design, since the 3D digital model provide animation, which helps designers to envisage visual changes as they apply various items, colors, pattern and fabrics.

Skin colors of females between the ages of 25-35 from Korea, China, and Vietnam were measured in Seoul, Beijing, and Hanoi using the Minolta CM-600d spectrophotometer. CIE Lab and Munsell HVC data of the face (forehead and both cheeks) and body (neck and arm) were analyzed using t-test, Analysis of Variance (ANOVA), Duncan's Multiple Range Test, Linear Regression Analysis, and K-Means Cluster Analysis using SPSS software. Korean females showed the highest L and V values for the face and body; Vietnamese females showed the highest b value in the face and the highest a value in the body. Higher L and b values for the face were related to higher L and b values of the body; this relationship was more prominent in Korean females. The younger age group (25-29) showed higher L values and lower b values than the older age group (30-35). Females from Korea, China, and Vietnam were grouped into Type 1 and Type 2 based on skin color. Type 1 had darker skin with more redness and yellowness and Type 2 had lighter skin with less redness and yellowness. A total of 88.2% of Korean females belonged to Type 2, 80.4% of Vietnamese females were Type 1, and Chinese females indicated an even distribution of Type 1 and Type 2.

Since $Gr{\"{o}}nadhl$ et al introduced a digital subtraction radiography into periodontal dignosis in 1983, many reports using this system has aimed to assess the peroiodontal disease activity and the alveolar bone changes after periodontal treatment. The present study was performed to evaluate the usefulness of digital subtraction radiography for asessing an alveolar bone changes in 3 months after periodontal flap surgery. Serial intraral raiographs were taken from 5 normal subjects and 6 periodontally diseased patients using customized bite blocks attached to film holder in fxation device and digitized by image processing system(consisting of IBM 386, digital frame grabber, CCD camera, Image-pro II software). And the reference parameters were measured by pixel unit and compared with respective radiographs. The serial radiographs showed a little and statistically insignificant difference in reference paramenters. The conventional intraoral radiographs, the subtraction images and the clor enhanced subtraction images were reviewed by 4 examiners and the examiner's agreement rates were compared. The subtraction images and its color enhanced images showed higher examiner's agreement rate than the conventional radiographs. And the propotions of sites diagnosed with bone loss or gain after periodontal surgery were highter in the subtraction images and its color enhanced images than in the conventional radiographs. Especially, in color enhanced images, the unber of bone agin sites tended to increase according to post-surgery periods. These results indicate that projection geometry could be standardized with the divice used in this study, and the subtraction radiography may be useful to assess an alveolar bone changes after periodntal flap surgery.
