This study explored the official memory of Korean War through the photographs of pictorial history books. The object of this study was two books of pictorial history that were published in America and China. Two books are Pictorial History of Korean War and The Glories of the People's Army of China. This study investigated symbolic meanings of the Korean War photographs through content analysis and visual analysis. This study analyzed the difference of official memory of Korean War in America and China. In Pictorial History of Korean War, the superiority of military strength was the memory of Korean War. While in The Glories of the People's Army of China, the superiority of socialism was the memory of Korean War. The Korean War photography actualized particular interpretations on Korean War.

Consumers changed to the subject to produce a digital contents as data transmission technique is advanced and a digital machine is diffused variously. Users are interested greatly in a user creative movie (UCM) production among various online contents. The UCM production method which uses the music and picture is the method that users make the UCM more easily. However, the UCM production service has the problem that any association does not exist in the music and picture and that the picture changes according to fixed time interval without the relation at a music rhythm. To solve this problem, we propose the UCM production method which uses a music analysis and picture analysis in the paper. A music analysis finds a picture change time according to the rhythm and a picture analysis finds the association of the picture. A music analysis finds strong parts of the sound which uses Root-Mean-Square (RMS). And a picture analysis classifies the picture as a scenery picture and people picture which uses structure simplicity of the picture(SSP) and face region detection. A picture analysis got correct result of 86.4% in the experiment and we can finds the association at each picture and arranges the sequence which the picture appears. Therefore, if we use a music and picture analysis at the UCM production, users may make natural and efficient movie.

수치정사사진지도를 제작하기 위한 기반 자료로 스캐닝한 수치항공사진영상과 항공사진의 왜곡 보정을 위한 표정, DEM의 추출과 편집 및 편위 수정에 이르기까지 다양한 처리절차가 필요하다. 또한 영상과 벡티 자료의 중첩을 통해 생선한 영상지도의 편집과 지도제작 작업에는 다양한 미적 요소가 필요하다. 본 연구에서는 수치항공사진 영상을 이용하여, 영상에 내포하는 기하학적 변위를 3차원 모델링 결과와 수치표고모델을 이용하여 소거하고, 수치정사사진을 제작한 후에, 1/5,000 수치지도에서 필요한 레이어와 중첩시킨 수치정사사진지도를 제작하여 그 정확도를 분석하였으며, 각 처리 단계별 문제점의 분석과 개선방안을 제시하였다.

칩을 분석하기 위해서는 현미경을 이용하여 칩 전체를 타일 형태로 나누어서 사진을 찍어 분석할 한 장의 사진을 완성하게 된다. 본 논문은, 타일형태로 부분 부분 찍은 사진들을 조립하여 한 장의 전체 사진을 완성하는 스티칭 방법에 관한 것이다. 사람이 수작업으로 일일이 사진들을 붙이려면 시간과 정확성이 떨어지므로 스티칭 과정을 자동화하는 방법을 제시한다.

This book deals with a .gesture of photography as a Political phenomena. In the gesture of photography, the conceptions that influences the cause and the policy of solutions that conflict the cultures, are developed. The contents of this book contains lots of items, and efforts to find the root of the digital revolution of nowadays.

Nowadays, as going to information society based knowledge, the informations are acquired, processed, serviced based digital environment. In surveying field, the trend have been changed from the analog foundation to the digital foundation. Also, aerial photogrammetry is being changed from analog aerial photogrammetry to digital aerial photogrammetry. In this paper, the analysis of accuracy is performed for the comparison of traditional aerial photogrammetry with digital aerial photogrammetry usign UltracamX in AT and Block Adjustment. As the results, Bundle adjustment in digital aerial photogrammetry with GPS/INS have more advantages than traditional independent adjustment in analog aerial photogrammetry. Digital aerial photogrammetry contributes the higher accuracy in AT and block adjustment more than analog aerial photogrammetry.

Analysis of lateral cephalometric radiograph (cephalogram) has been used routinely to evaluate skeletal and dental relationships, but analysis of the lateral facial photograph has not been used frequently for evaluation of skeletal relationships. As concerns about harm of X-ray irradiation increases, this study was planned to evaluate the possibility of substituting analysis of the lateral cephalogram with analysis of the lateral facial photograph by comparing these two analyses. According to the ANB values from cephalometric analysis, subjects were divided into three groups: Class I malocclusion group (n=32). Class II malocclusion group (n=32), and Class III malocclusion group (n=31). After measurements of angles indicating horizontal and vertical relationships of the maxilla and mandible on the lateral cephalograms and photographs, differences between Class I, II and III groups were evaluated. To evaluate the similarity between two similar values in the cephalograms and photographs, t-test using standardized variable Z and correlation analysis were performed in the Class I malocclusion group. The results showed that 1) SnN'Pg' on the photograph can be used to evaluate the antero-posterior relationship of the maxilla and mandible (ANB), 2) N'-Sn/Sn-Pg' on the photograph can be used to evaluate facial convexity (NA/APg), 3) Sn-Tra-Me' on the photograph can be used as a measurement similar to FMA. In conclusion, partly substituting lateral cephalogram analysis with lateral facial photograph analysis was possible in the evaluation of the maxilla and mandible.

1999년이래 순차적으로 수행되어지고 있는 항공사진 DB구축사업은 일반적으로 정확도가 검증되어진 항공사진전용독취기를 사용하여 항공사진영상 DB를 구축하고있으나, 일부기관에서는 시중에서 사용되는 일반자동독취기를 이용하여 항공사진영상 DB를 구축하기도 한다. 이에 본 연구에서는 항공사진전용독취기와 일반자동독취기를 정확도를 비교분석함으로서 항공영상 DB구축시 문제점과 타당성을 제시하고자 한다. 본 논문에서는 일반자동독취기의 활용 타당성을 분석하기 위하여 표정해석과 2차제품 제작을 통한 정확도를 항공사진전용독취기와 비교분석하였고, 자동독취기 검증 시스템을 개발하여 연구에 이용된 자동독취기를 검증함으로써 항공영상 DB구축에 있어서 필수적인 장비인 자동독취기의 정확도를 검증하였다.

최근 국내에는 다차원 공간정보 구축을 위하여 디지털 항공사진 및 항공라이다 장비를 이용하고 있으나, 위 데이터만을 이용하여 세밀하고 사실감 있는 3차원 공간데이터를 구축하는데 제한적이며, 고품질의 Texture Mapping을 위해 지상사진을 이용하지만 인력 및 작업 시간이 많이 소요된다. 이에 해외에서는 사실감 있는 3차원 공간정보 구축을 위하여 연직과 경사사진을 동시에 촬영하는 다각사진촬영시스템을 이용하고 있으며, 본 연구에서는 다각사진촬영시스템 개발시 고려해야할 경사사진 촬영 설계요소에 대하여 분석하였다. 연구결과 촬영고도, 카메라각도에 의하여 경사사진 주점의 거리, 지상해상도, 카메라 화각(FOV), 촬영영역에 대하여 분석할 수 있었다.

In the history of photograph, after the development of color photographs, those with multiple colors and high definition has gradually become the mainstream works in the field of photography. In the modern society of China that has been through reform and opening up, people's minds were increasingly liberated to widely accept color photos in terms of photography. Furthermore, the broad penetration of digital photography has brought together a new trend in the field of black-and-white photography. In line with this trend, more black-and-white photographs have appeared which are different from existing ones in the film-based period. In this recognition, the study seeks to compare the black-and-white documentary photograph works of Chinese photographers and analyze the modern Chinese black-and-white photographs.
