최근 다양한 기술의 발달로 인하여 시간과 공간의 제약 없이 관람객에게 사실감과 현장감을 표 현하며 관람객에게 실제적인 감각을 선사하는 실감미디어에 대한 관심과 시장이 늘어나고 있다. 모든 미디어는 기술 발전에 따라 더 실제적인 감각을 선사할 수 있는 콘텐츠를 제공한다. 기존 사각형의 영상 프레임에 머물던 디스플레이의 형태를 감상하는 환경과 다르다. 이러한 360도 영상은 콘텐츠 제작, 영상 렌더링 플랫폼 및 영상 이미징 장비 등 다양한 분야에서 적용되고 있 다. 전방위적인 360도를 제공하는 돔 형태를 통한 실감미디어 콘텐츠의 사례가 국내와 국외적 으로 늘어나고 있다. 하지만 이러한 상황에 비하여 360도의 돔 형태를 활용한 실감미디어의 콘 텐츠 사례 연구가 부족한 상황이다. 따라서 이 논문에서는 360도의 영상 개요를 살펴보며 돔 형태 영상의 디스플레이가 가진 특성을 알아보았다. 본 논문을 통해 360도 돔 형태를 활용한 실감미디어의 콘텐츠 사례들을 살펴보며, 이를 통하여 360도 영상을 기반으로 돔 형태를 활용 한 실감미디어 콘텐츠를 기획하려는 다양한 영상 창작자들에게 보탬이 되고자 한다.

As people's living standards and cultural standards have developed, interest in culture and art has increased, and the demand for large space structures where people can enjoy art, music, and sports has increased. As it accommodates a large number of personnel, it is most important to ensure safety of large spatial structures, and can be used as a space where people can evacuate in case of a disaster. Large spatial structures should be prepared for earthquake loads rather than wind loads. In addition to damage to the structure due to earthquakes, there are cases in which it was not utilized as a space for evacuation due to the fall of objects installed on top of the structure. Therefore, in this study, the dome-shaped large spatial structure is generalized and the displacement response according to the number of installations, position and mass is analyzed using a tuned mass damper(TMD) that is representative vibration control device.

In this study, a shape design and an analysis considering structural stability were investigated to develop an icosahedron-based hemispherical modular dome. To design this modular dome, a program that can perform icosahedron shape modeling, modularization of joint connection members, and the analysis of structural stability was developed. Furthermore, based on the adopted numerical model, the eigen buckling mode, unstable behavior characteristics according to load vector, and the critical buckling load of the modular dome under uniformly distributed load and concentrated load were analyzed, and the resistance capacities of the structure according to different load vectors were compared. The analysis results for the modular dome suggest that the developed program can perform joint modeling for shape design as well as modular member design, and adequately expressed the nonlinear behaviors of structured according to load conditions. The critical buckling load results also correctly reflected the characteristics of the load conditions. The uniformly distributed load was more advantageous to the structural stability than concentrated load.

A cable structures have the advantage that cover a large space without column but it is very sensitive to deal with shape control because of its flexibility. Especially, location of control member and needed elongation of member are important things. Therefore, the purpose of this paper is studied on displacement control technique for pre-stressed cable structures by force method considering order of control.
