Computer generated holography (CGH) is technology for generating holograms of synthetic, three dimensional (3D) objects which may not exist in the physical world. The process, however, requires heavy amount of computation as the resolution of a hologram is significantly higher than that of a typical optical image. This paper reviews four modern techniques for fast generation of digital Fresnel holograms which are important in the development of holographic video systems. The methods that will be described include the virtual window, sub-line, wavefront recording plane (WRP), and the interpolative WRP schemes. These works share the common objective to generate digital Fresnel hologram at a speed that is close to the video frame rate, and with complexity which is realizable with affordable computing and reconfigurable hardware devices. The author will present the principles and realization of these works, as well as some potential area of research in digital holography.

For rational agricultural land use planning, it is quite necessary to get hold of land suitability precisely and to make decision on land use patterns accordingly. In the methodological viewpoint, objective and scientific evaluation techniques for land suitability classification should be supported for the systematic land use planning. As one of technical development approaches to rational land use planning, this study tried to frame a land suitability evaluation system for agricultural purposes. Evaluation unit is defined as a tract of land bounded by road, other land units and topographical features. And quantification theory was applied in the determination works of evaluation criteria. The administrative area of Namsa-myon(district), Yongin-si(city), Kyunggi-do(province) was selected for the case study. In order to check the feasibility of the evaluation system developed in the study, field check team, consisting of 2 government officers and 2 representative farmers, carried out evaluation works by observation on 148 sample land units, 10% of total 1,480 ones. Between estimated and observed results, there showed very good relationship of its multiple correlation coefficient, R=0.9467.

With the increasing use of tower cranes higher than free standing height, the importance of lateral support is also growing. Since the fall of 43 tower cranes hit by the last typhoon 'Mami' in 2003, regulations and concerns about safety of construction equipment have increased and construction laws regarding lateral support have been strengthened. In Korea, where there are many large-scale apartment housing construction works with the development of new towns, Rope Guying is a more economical construction method than Wall Brace which fixes building structure like building wall and slab. The safety of this Rope Guying is not verified and many construction works are still carried out based on the experience of site managers. There has been no case of construction work where frame and measurements are applied. The objective of this study is to examine the safety of Rope Guying method and ensure the effective implementation of equipment and prevention of disasters.

This study deals with a comparative analysis of wooden assembly methods between Japanese traditional architecture and Kuma, Kengo's works. Kuma, Kengo has known as an architect who pursues Japanese architectural traditions with integrated solutions for built and natural environments, and expresses a deep commitment to unexpected use of materials such as stone and wood with the clarity of structural solutions. Accordingly, his architecture focuses on the appreciation of the spatial relationship with the surrounding, its local characters, and the selection of materials. This article first examines two of wooden assembly methods that have been shown in Japanese traditional architecture such as 'two-way system' and 'one-way system'. And then, Kuma, Kengo's wooden assembly methods in his works are analyzed and compared in relation to Japanese wooden assembly methods to find out similarities and differences between them. Then, it concludes that Kuma, Kengo's approach is not only relying on the methods of Japanese traditional architecture, but also exploring creative ways beyond traditional assembly methods.

This study has analyzed the main works of Hayao Miyazaki, a great master of Japanese animation, and inquired into the internal and external feature of characters depicted in his works. The creation of animation character starts from non-being in the planning step and becomes an important medium which will contain the story and the subject of drama. Therefore it's possible to analogize what he intends to represent through the identity, role and external feature of characters appeared in Hayao Miyazaki's animation. As a result of analyzing these external features, the message pursued by Hayao Miyazaki shows diversified girl character unlike the existing one of Japanimation, the girl characters in his works are sometimes sexless, sometimes androgynous, but they take the role to show the intention of director and to settle matters through new femininity free from any frame. In addition, the story of drama and other components show that the Japanese-typed is being sublimated worldwide with fantasy world through oriental appearance of girl character and various color symbols.

To design and construct a museum of art involves the interest of artists, architects, curatorship, management, and local government. More than this direct relationship, museum obliges the public a mission of delivering genuine public experience through art and architecture. However, most of Modern and contemporary architecture has not delivered genuine public experience of integrated art and architecture. Conceptual message of art and perceptual architectural exhibition space has not been integrated easily. Picture frame canvas initiated this schism and institutionalized museum management hampered the creativity of artists. This schism was overcome through artists' questioning of museum culture and creative works that embrace work and its environment. In contemporary culture, installation art and media art necessitates a new museum format which needs not only exhibition, but laboratory and interface space with viewers. This paper will regroup the existing museum according to its use and strategy, and reinterpret progressive museums that fosters young artists, and more than this, will introduce successfully established museums for new forms of art, which are equipped with versatile exhibition spaces, innovative interface between works and viewers, and own laboratory that can produce works of art. These examples will envision a creative method of art and architecture production that can achieve genuine public experience.

본 논문은 하나의 움직이는 카메라와 수시로 바뀌는 배경을 가진 환경 하에서 파라미터를 사용하지 않는 외곽선을 사용한 움직이는 물체의 외곽을 추적하고, 추적된 물체의 외곽을 다른 장면에서 가져온 배경으로 대체하여 추적물체를 제거하는 기법을 제안한다. 먼저 캐니 에지 이미지(map)를 수정하여 만들어 내고, 이들 에지들의 강도에 대한 정보를 LOD (Level-of-Detail)로 만든 결과 LOD 캐니 에지 이미지(map)을 생성한다. 이들 LOD 캐니 에지 이미지 화소에 대해 그래프를 사용한 경로 설정 방법을 사용한다. 이 작업으로 결정되는 외곽선을 이용하여 추적대상이 되는 물체를 다른 이미지에서부터 얻은 배경이미지로 대체함으로써 제거한다. 우리의 물체 추적을 위한 방법은 LOD 수정된 캐니에지 이미지를 위주로 이루어진다. 추가 에지 정보를 얻기 위해 LOD 계층에 따라서 자세한 외곽선 정보를 얻는다. 우리의 경로 설정 방법은 보다 강한 이미지 차에서 만들어진 에지 화소를 선호하는 것이다. 이 방법은 이전 외곽선 정보를 최소한으로 참고하기 때문에, 이전 외곽선 정보를 새로운 외곽선을 생성하는데 있어서 가중치를 사용 이전 외곽선을 포함시키는 방법에 비해 탁월하다. 외곽선 추적 후 추적 물체를 배경으로 대체하는데, 첫 이미지 배경은 이후에 나타나는 이미지로부터 추적 물체에 대해 가려진 배경정보를 가져오는 카메라 운동법이라 부르는 방법에 의하여 계산되어진다. 첫 프레임을 위한 배경 계산이 완료되면, 다음 이미지의 배경 계산은 첫 프레임의 배경에 의존한다. 본 논문에서 제시된 방법을 사용할 경우, 추적 물체의 형상 변화가 극심하지 않고, 카메라의 움직임이 매우 빠르지 않을 경우 성공적으로 추적할 수 있었다.
