오늘날 디지털기술과 결합한 사진은 현실과 허구를 결합하는 상호 텍스트성으로서의 사진이미지로 빠르게 변모하며 예술, 과학, 산업이 혼융되어 새로운 기능과 역할을 제시하고 있다. 디지털 사진과 재현의 새로운 관계 모색을 위해 적용된 디지털 포토그램의 다양한 사례를 Scanography, 3D Scanning작품, 나노과학기술과 사진이 만나 결합한 Nanogrphy, 렌티큘러 필터를 이용한 즉석 입체영상 배경사진 촬영 등을 통해 살펴보고 다양한 문화현상을 형성하고 새로운 시각적 패러다임을 제시하면서 문화변동까지 이끌어내는 디지털 사진의 확장가능성에 대해 연구한다.

This study aims to investigate that today's Mixed Reality Technology did not appear suddenly but has its beginnings in 20th century Visual and Interactive Art. First, Photographic Art expressed three-D on the two-dimensional plane and mixed images of reality and virtuality. Photogram made people experience both two-dimensional images and three-dimensional effects concurrently, and Photomontage combined various photos and mixed reality and virtuality. Next, Cinema tried to combine virtuality and reality using objets and CG. Early Cinema composed films and real objets. As computer technology developed, Cinema composed objet CG on real images and then tried background CG compositing. Finally, Telepresence Art tried a new possibility of Mixed Reality breaking the boundary between reality and virtuality, subject and object. It oscillates between virtual space in reality and real space in virtuality, or represents Mixed Reality by remote control of long distance participants. In the future, for the development and direction of Mixed Reality, there will be more need of referring to Visual and Interactive Art.

Animation which appeared with films in the late 19th century was a medium which came on obtaining nourishment from art historical style of modernism. However, the relation establishment between animation and modernism has been focused mainly on animation shapes, namely painted images. This sprang from explaining the relationship between animation and paintings, and for this reason, discussions of movements in animation were understood in tradition of chromophotograph of Muybridge and Jules Marey, or some characteristics owned by the live-action film. However, movements of animation were essentially different from the indexical sign of films or photogram, and objects of reproduction were different between them. Movements reproduced by animation are not ordinary movements, but expressions of or compressed movements and considerably systematic movements. As a result, these movements are far from reproduction of live-action film photogram. Rather, the logic of movements reproduced by animation comes near to controlling their motion scopes, time, distance etc. after dividing each part of the body. This is concluded in a standpoint of modern mechanism which is represented by Descartes and La Mettrie who tried to understand human body as a exchangeable machine. Design of modern mechanism ranging from modern society to industrial society and the age of modernism came to lead to analysis of physical motions of modern industrial society called composition of efficient movements understanding them as the law of nature rather than movements as nature. In the late 19th century, Taylor, F. W. and Gilbreth, Frank Bunker's studies of workers' working hours and 'motion study' were a way of constituting the frame of machine-human, which indicates that tradition of modern mechanism affected the entire modernism passing through industrial society. Further, we can see that motion studies conducted by them have almost similar characteristics to action analysis to study animation later in the name of 'timing'.

The purpose of this study was to evaluate the frequency of congenital missing teeth and supernumerary teeth in cleft patients. The subjects were divided into bilateral cleft lip and palate(BCLP), unilateral cleft lip and palate(UCLP) and cleft palate alone(CP alone) groups. 97 cleft patients(BCLP 15, UCLP 70, CP alone 12) between 6-20 years old were evaluated. Panorama film, Orthodontic chart and initial intraoral photogram were employed for this research. The obtained results were as follows. 1. The incidence of congenital missing teeth in total cleft samples was $57.7\%$, and the incidence of supernumerary teeth was $26.8\%$. Each incidence was higher than non-cleft. 2. The incidence of congenital missing teeth was the highest in BCLP and the lowest in CP alone. 3. The number of congenital missing teeth per perso was usually one, and the frequency was higher in the maxillary lateral incisors$(67.8\%)$, and maxillary second premolar$(14.9\%)$ than other teeth. 4. Most of tooth number anomalies in cleft patients were found in maxilla, especially adjacent region to the cleft site.

In this study, the accuracy of three dimensional location was improved by self calibration bundle method with additional parameter, which is to correct systematic error through detection and elimination of the gross error from updated reference variance for observation values in photogram-metry. In this study, with the result of comparing accuracy of each method, correcting systematic error is more effective after gross error detection and when observation values are contained more than two gross error the point with maximum correlation value is detected by masking effect of least square adjustment.
