2000년대 초부터 전통적인 가상 스튜디오 제작 시스템을 활용하여 수많은 교육 콘텐츠를 제작해 온 EBS는 약 20년만인 2020년 10월에 AR 영상 제작 시스템을 도입했다. 카메라의 움직임과 렌즈 정보를 트래킹하여 실시간으로 그래픽 요소와 실사를 합성한다는 기본 개념은 유사하지만, 새로 도입된 AR 영상 제작 시스템은 이전보다 개선된 몇 가지 최신 기술이 적용되었다. 좀 더 자유로운 카메라의 움직임을 가능하게 해주고 안정적으로 위치 트래킹을 할 수 있는 마커 추적 방식의 트래킹 기술이 적용되었고, 운영 소프트웨어는 컴퓨터 게임 제작에 활용되는 대표적인 그래픽 엔진 중 하나인 언리얼 엔진이 적용되어 시스템의 렌더링 부담은 줄어들면서 고품질의 실시간 그래픽 효과가 가능하게 되었다. 해당 시스템은 생방송 전용 스튜디오에서 부감 촬영을 담당하는 크레인 카메라에 설치되어 어린이 대상 생방송 프로그램에 주로 활용되고 있으며, 2D 그래픽으로 표현되던 코너 소개나 퀴즈 이벤트 등의 영상 중 일부가 3D AR 영상으로 전환되었다. 본 논문에서는 AR 영상 제작 시스템의 도입과 적용이 EBS의 콘텐츠 제작 측면에 있어서 어떤 변화를 가져왔는지와 향후 발전 방향과 가능성에 대해 알아본다.

The purpose of this study is to analyze the characteristics of current fashion illustrations within the framework of Multi-space method. Multi-space means being piled up one moment & space on others, and being amassed in a scene. This method is related with Dadaism, Surrealism and Postmodernism, and also influences on the current fashion illustration. In this study, the types of Multi-space method could be classified into 4 types; Repetitive Time Mixture in Multi-space, Juxtaposed Time Mixture in Multi-space, Reiterated Space Mixture in Multi-space, Projected Space Mixture in Multi-space. The characteristics of Multi-space were analyzed and the results are as followed. The distinctive methods for Time Mixture in Multi-space are repetition and juxtaposition in a scene. Time Mixture in Multi-space can make the nonlinear narration and unreal illusory space in fashion illustrations more effectively. Reiterated Space Mixture in Multi-space can be related with the heterogeneous, surrealistic illusions in current fashion illustrations. Projected Space Mixture in Multi-space can be characterized into inter-penetration. It can derive spectators to mix the projected & transparent images in a scene for their own imaginary stories. The final imagination can be made differently according to the personal experiences of spectators.

Chuneunja(天隱子) was publication that described the life nurturing(養生) of Taoism, consisted of 8 chapters. It was comparative primary writing and contained important contents in related to the life nurturing of Taoism. It belonged to the life nurturing of Taoism that influenced by Confucianism and Buddhism. It emphasized on the practical and rational thought that mastered morality by performing gradually. It showed the concrete asceticism method like to the basic regimen training of Taoism, for example mind control(調心), flesh control(調身), breath control(調息), conduction exercise(導引), raping teeth (叩齒法) and swallowing saliva(嚥津法). Oriental traditional regimen focused on realizing balanced human character by practicing human mind and body. It may show the direction to modern person that are troubled with harmful effect of modern civilization. If we throw away superstitious and unreal part in the traditional regimen and apply regimen in one's life, we may consider that regimen contribute to human health. Therefore, we require clear understanding for the classic data inherited from predecessors.

The inspiration and its application in fashion design is considered as one of the important factors in boosting the fashion arena. Many inspirations are adapted in fashion de-sign and they make the fashion design unique and characteristic. In this study many fashion designs are analyzed to find what kind of inspirations were adapted and utilized for the fashion design in reality. The nature historic costumes ethcin costumes arts sciences literature music sports were revealed as the sources of fashion inspiration.l The concerns on the environments movies and dramas could provide inspirations in fashion as well. Several contents or steps were studied to provide the one of the example of appli-cations as follows: 1. The works of Marc Chagall were analized to figure out and several plastic characteristics from his works were revealed such as fantastic strong colors unreal animal pattern or their details his wife and friends various divisions of the surface and so on. These attributes had been favored in depiction of his works to ex-press his home town or nostalgia. 2. '90s fashion designs inspired by the works of Chagall were analized to find out the meth-odology or the process of designs. The same Chagall colors were used in design and similar pattern were expressed through beaded work or printing jobs. The surface designs such as printing were the most prefered method in adapting the inspirations. 3. The plastic characteristics of the work of Chagall were attempted in clothing design and construction. The color combination patterns which remind the animals the surface divisions were used in design ot practive the methodologies.

The catenaries must guarantee the constant electricity to the trains, so that the safety and the estimate of fatigue degree and the inspection of abrasion degree should be done rapidly. This thesis proposes the system that can manage the performance/failure of the catenaries using the image process as the solution for the weak points of the existing inspection such as the decrease of immediateness and the lack of constancy in the human resources. This study simulates the ALD using VHSV (Virture HSV) which is the unreal HSV images, not getting the real HSV in ages to the image processing technique that repeats the erosion and the expansion of the images as the methods that can monitor the slight/critical defects of the catenaries as dealing with the result of the catenaries inspection images. The final ALD (Abnormal Line Detection) system is designed based on this simulation. I have demonstrated it with the VHSV (Virture HSV) virtual images as the materials of the test and inspected it through testing the defects of the catenaries for the thesis.

Results of flat plate compressible boundary layer calculation, based on discrete formulation of DSMC method, are presented in low Mach number and low Knudsen number range. The free stream is a uniform flow of pure nitrogen at various Mach numbers in low pressures (i.e. rarefied gas). Complete thermal accommodation and diffuse molecular reflections are used as the wall boundary condition, replacing unreal no-slip condition used in continuum calculations. In the discrete formulation of DSMC method, there is no need to use ad hoc assumptions on transport properties like viscosity and thermal conductivity, instead viscosity is calculated from values of other field variables (velocity and shear stress). Also the results are compared with existing self-similar continuum solutions. In all Mach number cases computed, velocity slip is most pronounced in regions near the leading edge where continuum formulation renders the solution singular. As the boundary layer develops further downstream, velocity slips asymptote to values that are between 10 to 20% of the magnitude of free stream velocity. When the free stream number density is reduced, so the gas more rarefied, the velocity slip increases as expected.

The purpose of this study was to show a theoretical system of expressional area, the characteristics and the effects which is applied to fashion illustration by metaphor theory. The theoretical system of expressional area was analyzed by category analysis and 150 fashion illustrations from 1900 to 1999 were analyzed by contents analysis. The results of this study were as follows: Metaphor in fashion illustration was categorized to replacement, parody, heterogeneous combination, surrealism, magnification and reduction of size, optical illusion, juxtaposition and distortion of form. In detail, First, replacement was showed omission of form, non-object color, texture. Second, parody was showed using the part in artistic work, differentiation of original work. Third, heterogeneous combination was showed unreal body combining between animal and plant. Fourth, surrealism was showed creation of object which is impossible to present. Fifth, magnification and reduction of size was showed bizarre magnification of part of body, size of clothing. Sixth, optical illusion was showed ambiguity of object because of creation of new form. Seventh, juxtaposition was showed the parallel of contradicting idea and change of meaning between heterogeneous objects. Eighth, the distortion of form was showed grotesque distortion of part of body and disgusting object.

This research aims to analyze humorous images expressed in 2D graphics fashion illustrations and to propose application of 2D graphics in humorous images for fashion illustrations to suggest a more creative and relevant fashion illustration for contemporary culture. The result of this research were as follows: First, theories on reaction of humor can be classified into Incongruity theory, Superiority theory and Arousal and Relief theory. Humor in visual arts are classified in Visual Parody, Visual Pun, Visual Paradox and Visual Satire. Second, Visual Pun, Visual Parody, and Visual Satire are used for visualizing fashion illustration, and the foundations for many humor images were simple-colored, imaginative, and unreal settings. And it was also found out that the physical proportion of the models generally was 1(head):7(entire body), 1:8, 1:15 and the models were usually laughing and smiling. Tone was usually pastel and vivid, and posture was usually standing-position or sitting-position. Third, based on such results, fashion illustration works of humor image using 2D graphics were created. To concretize the humor image, 'gift' as a concept was chosen. Humor alleviates the tension and stress. It also brings laughter and pleasure to people's lives. Therefore humor image will be an effective way of expanding creativity in modern fashion illustration.

In this study, the sensitivity analysis of bed changes due to the various sediment transport equations have been conducted for 80 km reach of the Lower Nakdong River using the HEC-6 which is one dimensional numerical model. The bed elevation changes according to the different sediment transport formulas were compared and analyzed quantitatively. As a result of the numerical simulation, the final bed elevation calculated by Engelund and Hansen(1967), Ackers and White(1973), and Yang(1979) formulas was similar to one another in configuration. The bed change simulated by Engelund and Hansen(1967) were greatest among them, for example, 5.5 m deposition and 2.9 m erosion for 100 years. Also, in the case of Toffaleti (1969) equation, the maximum bed deposition of 8.04 m after 100 years was induced at the 73 km location upstream of the Nakdong River Estuary Barrage. Meyer-Peter-M$\ddot{u}$ller(1948) and Wilcock(2001) formulas produced the deposition only at the upstream end and there was little bed change in the downstream area. The unreal bed configuration of continuously up and down pattern was simulated by Laursen(1958) transport equation.
