현재까지 알려진 대부분의 워터마킹 기엽들은 여러 가지 공격에 대한 강인성과 워터마킹 된 영상의 비가시성을 동시에 만족하기 위하여 중간주파수 영역에 워터마킹을 삽입한다. 그러나 본 논문에서는 이산 웨이블릿 분해 연 영상의 저주파 대역에 가우시안 랜덤 시퀀스를 삽입함으로써 강인성을 높이고 화질 열화가 발생하는 계수에 대하여 워터마크 삽입을 생략함으로써 비가시성을 만족하도록 하였다 제안한 방식은 최저주파 대역의 이웃픽셀과의 상관도 계산에 의하여 워터마크를 삽입함으로써 추출 시에도 동일한 과정을 통하여 원 영상 없이도 워터마크를 검출할 수 있도록 하였다. 벤치마킹 도구를 통한 시뮬레이션 실험결과를 통해, 제시한 방법이 기존 연구와 비교하여 우수한 강인성을 보였다.

The purpose of this study was to investigate the actual wearing conditions and the preferences of knit wear school uniforms. The subjects were 480 high school girls from 6 high schools placed in Daejeon. The method of study is a survey consisted of actual wearing conditions questionnaires, preferences questionnaires, and demographic attribution. Data was analyzed by frequency, variance, crosstabs, and correlation analysis using SPSS 12.0 program. The results of study are as follows. First, high school girls over 90% wearing knit wear school uniforms were satisfied with current knit wear school uniforms(navy color, V-neck, and wool mixed). Second, high school girls preferred 100% cotton material and black/white/gray color group. The style of knit wear school uniforms was most preferred monochrome cardigan with cable pattern. High school girls wanted to show neat image by knit wear school uniforms and to diversify the style of them. Third, the differences of preferences between groups, they were wearing knit wear school uniforms(A group) or not(B group), were about pattern and improvement. A group preferred school mark pattern, and wanted to improve the quality and after service. B group preferred monochrome cable pattern, and wanted to diversify the style. Both groups wanted to wear knit wear school uniforms because knit wear was 'warm' and 'comfort'. Consequently, knit wear school uniforms will help high school girls express individuality and beauty.

This study attempted to creat patent map 163 cases of patent for technology of apparel design using computer technology and researched the trend of Patent application by count교, technologies, applicant and filing date. In regard to application by country, the United States mark the first place with 99 cases (61%), Japan marks the second with 34 cases (21%), Korea the third with 19 cases (12%). Comparing the patent applications in specialized technologies, we find the United States is overwhelming the technologies for garment Production Process, Patterning Process and preparatory process, and Japan is currently undergoing development work in this area, while most of Korean applications are focused in the technologies for selection or substitution methods related to Purchase and sale of apparels, body image and design service Therefore, it is required to preoccupy and defend patent rights as well as develop technologies aggressively and extensively in preparation for the expansion of e-commerce market. Analysing the speed of progress in technology in terms of number of applicants and application cases, we can say it entered into developing stage from the middle of 1990s and it seems that they will continue the development work from now on. in case of Korea, they began in 1996, somewhat late, but reached a similar level with the United States in 2000.

With supplied computers and the development of information and communication thropugh the Internet, the space of personal home pages in potal sites has been filled with photos taken by digital cameras, and 'the introduction of privacy' done in the personal home pages has become a general trend in society. As the use of Photoshop, available to edit and modify digital photos, in this social atmosphere, has grown general, they have shown their interest in the retouching technique of Photoshop. Computer graphics, marked based on the treatment of a variety of information into pictures or a technology to mark it, recently various application methods have been found in make-up. Especially, Adobe Photoshop, used to edit and modify images, is a sofetware program proper to perform beauty make-up in correcting and creating images in an effective way. The purpose of this study is to express each factor in Adobe Photoshop CS2 about the beauty make-up. As a result, I can say, the process that digital image is retouched by Adobe Photoshop CS is similar work to beauty make-up. The process of Photoshop retouching can be used as the materials for educating of make-up and as the materials for presentation of beauty make-up trend. And also we can serve the simulation to the customer before real make-up. Therefore, this study is for the effective performance of diverse beauty makeup integrating retouch technique with Photoshop CS.

본고는 컴퓨터 게임 디자인의 학문적 연구를 위한 초기적 시론을 목적으로 한다. 수용자의 행동, 반응의 영역과 메시지의 소통의 디자인까지를 포괄하는 확장된 의미의 커뮤니케이션 디자인론의 설정을 통해 컴퓨터 게임 디자인을 새로운 커뮤니케이션 현상의 디자인으로 이해할 수 있다. 컴퓨터 게임의 커뮤니케이션으로서의 특징은 첫째, 기록과 그것의 단순한 재현으로서의 커뮤니케이션이 아니라 수용자의 창조적 재현이 중요한 매체이다. 둘째, 그 제작과정이 프로그램 공학과 멀티미디어 디자인의 종합적인 요소가 통합된 다층적인 것이다. 여기에 덧붙여 마크 포스터(Mark Poster)꼭 뉴 미디어 이론을 원용할 때 정보 시뮬레이션으로서 컴퓨터게임의 뉴 미디어적인 특성을 확인하게 된다. 이러한 이해는 앞으로의 컴퓨터 게임의 디자인은 단순한 기술구현과 시각적 형상의 창조를 넘어서 사물과 세계를 경험하는 방식의 창조성과 주체성을 연습하는 훈련의 장을 디자인하는 것으로 그 방향을 추구해야 하리라고 생각된다.

According to the analysis which investigated visitors of HACCP system certified stores and non-visitors of such stores on the awareness of HACCP for livestock products, 77.1% (246 pollees) heard of HACCP certification for livestock products, 67.1% (214 pollees) had seen the HACCP certification mark for livestock products, 62.1% (198 pollees) heard of HACCP certification for livestock products in meet retail shops, and 51.4% (164 pollees) were not aware of the recent TV · subway advertisements regarding HACCP certification for livestock products. For every questionnaire on the awareness of HACCP for livestock products, visitors of HACCP system certified stores showed significantly higher response rate than nonvisitors (p<0.01, p<0.001). The majority of pollees (74.9%, 239 pollees) replied that the word HACCP for livestock products brings up the image of safe livestock products, and 37.0% answered that the term HACCP defines 'Hazard analysis critical control point'. Regarding the questions on HACCP system for livestock products, 38.6% showed that they were most curious in terms of the benefits of such system. The demand analysis on HACCP for livestock products for consumer was also conducted. In the analysis, the demand for support of the policy (4.06 points) was higher than demand for education · public promotion of HACCP (4.03 points) and demand for related application (3.90 points).

A bullet launcher can be developed as a smart instrument, especially for use in the military section, that can track, identify, detect, mark, lock, and shoot a target by implementing an image-processing system. In this research, the application of object recognition system, laser encoding as a unique marker, 2-dimensional movement, and pneumatic as a shooter has been studied intensively. The results showed that object recognition system could detect various colors, patterns, sizes, and laser blinking. Measuring the average error value of the object distance by using the camera is ±4, ±5, and ±6% for circle, square and triangle form respectively. Meanwhile, the average accuracy of shots on objects is 95.24% and 85.71% in indoor and outdoor conditions respectively. Here, the average prototype response time is 1.11 s. Moreover, the highest accuracy rate of shooting results at 50 cm was obtained 98.32%.

Lunar permanently shadowed regions (PSRs) never see direct sunlight and are illuminated only by secondary illumination - light reflected from nearby topography. The ShadowCam imaging experiment onboard the Korea Pathfinder Lunar Orbiter is acquiring images of these PSRs. We characterize and discuss the nature of secondary illumination for the Shackleton PSR from ShadowCam radiance-calibrated images. We also use modeling to understand the magnitude and direction of the secondary illumination. Results from our analysis highlight the non-homogeneous, dynamic, and complex nature of PSR secondary lighting. Knowledge of the direction of the secondary illumination is crucial for reli-able interpretation of contrasts observed in ShadowCam images. This preliminary analysis of the floor of Shackleton crater from images acquired over multiple secondary illumination conditions does not reveal indications of exposed surface ice, even though temperatures are constantly below 110K.
