Compressing image data by using Vector Quantization (VQ)［1］-［3］will compare Training Vectors with Codebook. The result is an index of position with minimum distortion. The implementing Random Codebook will reduce the image quality. This research presents the Splitting solution ［4］,［5］to implement the Codebook, which improves the image quality［6］by the average Training Vectors, then splits the average result to Codebook that has minimum distortion. The result from this presentation will give the better quality of the image than using Random Codebook.

A purpose of this study is to 6nd out how the casual and formal style clothes of stripe pattern giving variety by pattern direction, pattern width, and contrast coloration have an effect on image of wearers. For this, 192 stimuli were made and 1200 testee evaluated them using semantic differential scale. As a result, five image dimensions were drawn as a factor of attractiveness, gracefulness, activeness, visibility, and tenderness. Unlike the value contrast previously researched, it showed that chroma contrast coloration which was interacted with a color tone contrast coloration had an effect on all the 5 image dimensions. This result was recognized as significant clothes dues in evaluating the image of stripe wearers. Besides, clothing style, stripe pattern, and contrast coloration were made clear as an efficient parameter in image presentation of clothing wearers.

The NDT using ultrasonic is largely divided into A-Scan and C-Scan methods. Since A-Scan method is subject to subjective judgement by trained personnel, C-Scan method has been introduced, which presents the weld area in two dimensions by placing the transducers two dimensionally used in the A-Scan method. Therefore, it is necessary to develop equipment that can provide weld quality without the help of a welding expert and the presentation of effective C-Scan images. Thus, in this paper, the algorithms that express a low resolution 2-dimensional gray image formed by C-Scan method as a high-resolution color C-Scan image and automatically determine the weld quality from the generated C-Scan color image. The high resolution color C-Scan images proposed in this paper allow the exact shape of the weld point to be expressed, and an objective algorithm to use this image to automatically determine weld quality.

한국의 애니메이션은 디지털 영상시대에 국가 전략 산업이란 이름 아래 명칭과 개념의 통일된 코드도 없이 지난 수년 동안 세계 최고 수준의 인프라가 형성되었다. 비교육적이고 경박한 문화에서 각광 받는 돈벌이로 현대의 시대성과 가장 밀착된 표현 형식으로 새롭게 평가 받고 있는 것이 디지털 애니메이션이다. 지난 30년 동안 대중 영상 매체에서 접한 애니메이션은 거의 전부 만화 영화였다. 결코, 예술로서 존중하지 않지만 늘 가까이 두고 기호품과 같은 만화 영화는 예술성과 문화성과는 별개로 자연스럽게 두터운 매니아 계층을 확보했다. 본 논문은 교육을 목적으로 하는 모바일 컨텐츠를 위한 애니메이션 알고리즘을 제안하고 이것을 이용하여, 가상 패류 박물관, 가상 화석 박물관을 설계 및 구현 하였고 1000여 가지의 동작표현 컨텐츠를 구축하였다. 사용자들은 상호 작용에 의해서 애니메이션 객체를 360도 회전시키거나 축소, 확대 등이 가능하다.

Purpose: The purpose of this study is to examine the effectiveness of Problem-based Learning (PBL) in an interdisciplinary college class. This class was run under the theme of 'Nurse Social Content Creators' (NSCC) in the Korean Nurses Association (KNA)'s industry-university collaborative project designed to promote a positive image of nurses among the public. Methods: Study 1 examined changes in perception about nurses among the PBL participants before and after the program. A one-group pre-post test experimental design was applied, and the data were analyzed using a Wilcoxon signed-rank test. Study 2 identified differences of perceptions of nurses between people who had observed the PBL final presentation and people who had not. A post-test-only with nonequivalent group experimental design was used, and the data were analyzed using a Mann-Whitney U test. Results: Study 1 revealed a significant increase of positive perceptions towards nurses. Study 2 revealed a significant difference between the PBL presentation audience group and the control group. Students who had observed the PBL program showed more positive perceptions of nurses than students who had not. Conclusion: This research is an important study with high practicality in the area of media studies as well as in nursing. The PBL teaching method was proven to be effective in enhancing perceptions of nurses.

현대사회에는 수많은 영상미디어의 홍수 속에서 영상미디어는 급속도로 발전하고 있다. 송신자와 수신자 사이의 효과적인 커뮤니케이션 수단으로 영상표현 기법의 한 분야인 모션그래픽이 대두되고 있는 실정이다. 모션그래픽은 수신자에게 정보를 보다 쉽고 정확하게 전달하기 위해 시각정보의 명확성을 부여하고 이미지의 전달과 정보전달의 효과를 높이기 위하여 커뮤니케이션 과정의 효과를 증대한다. 본 연구에서 논자는 사례를 통하여 최근 관심이 커지고 있는 모션그래픽의 한 분야인 타이틀 디자인이라는 짧지만 함축적인 정보의 전달로 강력한 시각전달로 모션그래픽의 표현방법상의 연구와 구조를 분석하여 실무제작에 있어 보다 낳은 방향으로 커뮤니케이션의 편리성과 효율성을 향상시키기 위한 모션그래픽의 제작방법을 조명해보고자 한다.

To investigate and analyze of the human brain-wave changes during 3-dimenslonal image load were expected to take not only an important basic information of 3-dimensional TV usage but also 3-dimensional image design. In this experiment, to analyze the difference of visual analyze handing system for which we present the 2- dimensional image having no parallex and 3-dimensional image by visual evoked potentials(VEP). 2-dimensional image and 3-dimensional image displayed on the screen through video. In the test, the time interval was one sec for presentation of stimulus considering united time of visual information of right eye and left eye during watching the 3-dimensional image also display time interval was 200 mesc for each stimulus image. Results are as follow, (1) N190 appears faster 16msec-20msec in the point of Fz, Cz, Pz, Oz when loaded 3D4 angle than 2D3 angle. (2) About of the P300, 3D4 angle(Otherwise, Oz point was reverse) and in the case of no equipment of liquid crystal shutter, there appeared PEAK near the P250. (3) There were 5% significant difference when the liquid crystal shutter was equiped and didn't, Therefore, this phenomenon show the possibility that Liquid crystal shutter influences on Visual Evoked Potentials.

본 논문은 자기제시와 브랜드 선호도의 관계에서 체면민감성과 사용상황의 조절효과를 알아보고자 하였다. 충남지역에 소재한 대학교의 학생들을 대상으로 자료를 수집하였다. 분석결과는 다음과 같이 요약될 수 있다. 우선 공적 사용 상황에서든 사적 사용상황에서든 상징적 브랜드 선호도에 대한 자기제시의 효과는 유의하지 않았다. 반면, 두 가지 상황 모두에서 기능적 브랜드 선호도에 대한 자기제시의 영향은 유의한 것으로 나타났다. 둘째, 체면민감성의 주효과는 공적 상황에서 기능적 브랜드 선호도에 부적인 영향을 미칠 때만 유의할 뿐 다른 경우에는 유의하지 않았다. 셋째, 자기제시와 체면민감성의 상호작용효과를 보면, 공적 상황에서든 사적 상황에서든 체면에 대한 민감성이 상대적으로 낮은 사람들은 자기제시 수준과 무관하게 브랜드 선호도의 변화가 크게 나타나고 있지 않았다. 본 연구는 사용 상황이 공적이든 사적이든 체면민감성은 자기제시와 상호작용을 통하여 브랜드 선호도에 영향을 미침을 밝히고 있다는 점에서 의의를 찾을 수 있다.

Earthquake disaster frequently happens in Shizuoka Prefecture and it is commonly predicted that a giant earthquake(Tokai Earthquake) could occur in the near future. When a giant earthquake happens, extensive damage of lifelines will be expected. It is considered that the collection of damage information and the establishment of a communication network system are very important in order to restore lifelines quickly. And geographic information system(GIS) might playa very important role to grasp the spatial information of lifeline damage in a natural disaster. The authors' group had a research project to study a lifeline restoration support system with image processing and ad hoc networking in a natural disaster. The objectives of this presentation are to introduce our project and to show some results of our study. The authors finally constructed the GIS for the integration of damage information acquired by image processing and ad hoc networking.
