In this paper, we propose and implement a high-speed algorithm for CGH that is to calculate digital hologram by modeling the interference phenomenon for tow lights. This algorithm changes the computation equations into a parallel-computable ones and implements it with a structure consisting of two kinds of cells (initial calculation cell, and update calculation cell). The parallel computation algorithm is to get the rest hologram pixels concurrently after calculation the first hologram column. Here, the initial calculation cells compute the first column of the hologram and the update calculation cells compute the rest of the hologram. The two kinds of cells performs a pipeline operation to complete the operations of the two cells at the same time. A CGH calculator to compute the hole hologram for a light source is structured by arranging the two kinds of cells. Results from simulation showed that the maximum operation frequency is about 215MHz. So, experiments are performed by setting this frequency and the same environments as the method showing the best performance. As the results, the proposed one could complete the computation of 81.75 CGH frames per second, while the previous method computes 62.9 CGH frames per second.

Aroma therapy was used for religious or healing purpose in the world throughout the history. In these days, numbers of people use aroma therapy for various reasons such as mental health issue. Aroma diffusers are made with various subjects, but most are made with volatilization and candle by using fumigation method. Korea's a grayish-blue-powdered celadon has insignificant position in both traditional and cultural value. Grayish-blue-powdered celadon must constantly develop its style and design and collaborate with modern product to meet the demand of the today's market. In this research, it will find the method to develop an aroma diffuser by using a grayish-blue-powdered celadon to meet consumer's demand. And ultimately, this research will construct a cultural infrastructure based on traditional image and by adding more value on the traditional ceramics market.

Through this thesis, I intended to analyze Hollywood animation through that achieved in box office by directing viewpoint. of Chris Sanders and Dean Deblois not only shows standard narrative structure of adventure, comedy, fantasy, but also express message of story and thorough visual. Analysis of directing classify contents and form. In contents, constitution of narrative and set up of character, irony of plot, characterization and popularity are embossed. In form, lighting and special effect, design and layout, 3D technology and stereoscopic camera technique based on the capital strength are outstanding. The high evaluation for film is possessed of box offic, remained within value and popularity, and delivered metaphysical theme without repulsion. The director's direction make success even if the pre-production manage by huge system approach.

The 3-D shape use to effect of movie, animation, industrial design, medical treatment service, education, engineering etc.... But it's not easy to make 3-D shape from the information of 2-D image. There are two methods in restoring 3-D video image through 2-D image; First the method of using a laser; Secondly the method of acquiring 3-D image through stereo vision. Instead of doing two methods with many difficulties, I figure out the method of simple 3-D image in this research paper. We present here a simple and efficient method, called direct calibration, which doesn't require any equations at all. The direct calibration procedure builds a lookup table(LUT) linking image and 3-D coordinates by a real 3-D triangulation system. The LUT is built by measuring the image coordinates of a grid of known 3-D points, and recording both image and world coordinates for each point; the depth values of all other visible points are obtained by interpolation.

최근 국가균형발전을 위한 문화콘텐츠산업의 비중은 날로 커지고 있으며 디지털 컨버젼스의 중심으로 부각되고 있다. 이러한 시대적, 사회적 요구에 즈음하여 정부의 지역문화 콘텐츠 육성 의지에 부합하는 전통건축물의 e-Learning을 위한 웹 기반 저작도구의 구현방법을 제안하고자 한다. 지금까지의 전통건축의 복원 및 재현은 전통적인 전수방식에 의존하거나 다분히 현상적인 수준에 그치고 있어, 우리 문화에서 중요한 위치를 차지하고 있는 전통건축물에 대한 저변의 확대와 보편적이고 대중적인 이해를 돕기에는 한계가 존재하는 것이 사실이다. 또한 전통건축에 관련한 교육자료는 대부분 고서(古書)나 텍스트에 의존하고 있는 것이 현실인 점을 감안할 때, 시각적이고 인터랙티브한 e-Learning 시스템의 연구는 필수적이라 할 것이다. 연구의 범위로서는 한국문화콘텐츠진흥원의 진행 중 사업인 문화원형복원사업인 "조선시대 탐라순력도의 디지털콘텐츠 개발"의 내용을 토대로 하며, 조선 중기인 17세기 제주도의 주심포계 전통건축을 대상으로 하고 있다. 본 연구의 내용은 1) 17세기 중엽 제주도의 주심포계 전통건축물에 대한 가구구조의 형성관계 및 그 형상을 디지털화하기 위한 데이터 체계를 제안하고, 2) 이에 따른 웹 기반의 가상전시 및 e-Learning 콘텐츠를 위한 시스템 구축의 프로토타입을 제시하며, 3) 상기 제시한 데이터 체계에 근거한 사용자 중심의 전통건축물 재현을 위한 3차원 저작환경 및 그 인터페이스를 제시한다. 이 결과로 전통건축물의 형성원리를 이해하고 전통 양식에 근거한 창의적 저작이 가능한 환경을 제시함으로써 멀티미디어 저작물 및 디자인 협업, 전통건축 유지보수 분야 등에 파급효과를 기대할 수 있다. 더불어 제안된 내용에 근거한 향후 연구로 전통건축물에 대한 일관되고 통합적인 관리방안과 그 실현수단에 대한 논의를 비롯하여 전통문화를 소재로 한 디지털 콘텐츠의 활용방안 및 그 부가가치에 대한 논의가 병행되어야 할 것이다.

The purpose of this study is to analyze the 'Framework for Information Literacy for Higher Education' filed by the ACRL (Association of College and Research Libraries) Board on February 2, 2015 and adopted on January 11, 2016. Six concepts central to information literacy in Framework and four main theories or models (i.e., threshold concepts, metaliteracy, Backward Design, and Liminal Space) underpinning the Framework were analyzed. The Framework provides conceptual or descriptive approach. In addition, the Framework is not designed to be implemented in a single information literacy session in a student's academic career. Instead, it is intended to be systematically integrated into the student's academic program at variety of levels. This study recommends curricular development and assessment methods supporting Framework as a further study.

In the spatial image composition of a cathedral, light is the most important element of changing the mind through vision. The religious meaning of light and its impact on human sensibility are believed to be very large. Therefore, in this study, 'Illuminance' is the most important research subject of a cathedral's worship space lighting plan elements. Illuminance is expressed by giving the clarity and form of space through a subtle spatial composition difference. The role of illuminance is essential for confirming the existence of space, and lighting controls the spatial atmosphere at an appropriate level. The standard and range of illuminance are set through the synthesis and analysis of related standards. Based on this, a related case study was conducted on cathedrals built in the Gangnam area of Seoul in the 1980s. The lighting-related factors were analyzed and the illuminance of the liturgical space and worship area were measured. The appropriate level of applicability was confirmed by comparison analysis. A plan for the illuminance application levels and elements applied in the cathedral lighting design is proposed.

Tensegrity is a relatively new structural system based on the use of continuous tension-discontinuous compression. Of course, a much more detailed structural investigation would be necessary, but at least in order to achieve the intended purpose, it is essential to understand the structural principles and the fundamental forces of tensegrity. Once this point is established, the applications of them to architecture are described, as well as the characteristics of these structures. Then, in spite of the controversial definitions to explain these systems, several examples of tensegrity prototypes or modules constructed in iESD(Institute of Environmental Structure Design) are presented to illustrate the feasibility of tensegrity as a lightweight structure. In this work, consequently, the reformability and application of tensegrity modules have also been researched in architecture, after the patterns of basic module as well as fundamental definition are introduced.

This article aims to provide an overall picture of the applications of serious games for social changes. Our main goals are to show that game has great potential in delivering messages for social changes and to suggest guidelines for researchers and game developers in designing related games. We synthesized the key concepts of games for change that make them promising through literature reviews and analyzing game lists for social changes. Based on the theoretical investigations, we found that both role-taking and simulation of games are powerful ways not only to influence attitudes toward the other side but also to bring out empathy as psychological mechanism to draw attitude changes and altruistic actions associated with social or political issues.
