With the development of digital technologies, CAID became an essential part in the industrial design process. Creating photo-realistic images from a virtual scene with 3D models is one of the specialized task for CAID users. This task requires a complex interface of setting the positions and the parameters of camera and lights for optimal rendering results. However, the user interface of existing CAID tools are not simple for designers because the task is mostly accomplished in a parameter setting dialogue window. This research address this interface issues, in particular the issues related to lighting, by developing and evaluating TLS(Tangible Lighting Studio) that uses Augmented Reality and Tangible User Interface. The interface of positioning objects and setting parameters become tangible and distributed in the workspace to support more intuitive rendering task. TLS consists of markers, and physical controller, and a see-through HMD(Head Mounted Display). The user can directly control the lighting parameters in the AR workspace. In the evaluation experiment, TLS provide higher effectiveness, efficiency and user satisfaction compared to existing GUI(Graphic User Interface) method. It is expected that the application of TLS can be expanded to photography education and architecture simulation.

In Korean language, 'changeu'(originality) and 'changjo'(creativity) has been used as almost same meaning, because these have similar pronunciation. However, originality means idea and creativity means process. The former is based on intuition, and the latter is on both of logic and intuition. Intuition process is not perceived very well, but logic has very clear one. We can find the due for that creating something is not difficult too much anymore, because the process is identified. The creation process is a problem solving process and it has the design on its center. Designer study the problem solving process and learn how to solve the problem with many cases on its studio class. Then we can call them as a creator. The meaning of design that it is a styling is very usual in Korean public and even designers. However, it will be not valid anymore in the upcoming digital age, which reproduction is possible with a little restriction. Design should be back as an original methodology for creation with the designer's own capability such as conception, intermediation, and visualization.

Subject of this Study is focused on set design for short animation, GHOST, made and presented by animation studio, BEYOND PROSCENIUM. Sets in animation have several functions. First, sets are a playground that character can play to lead a story. Second, sets explain background, which is time and space. Third, sets can visualize metaphorical meaning or symbolic system in animation. To obtain final design that is sufficient to those functions, this study analyzes the case that metaphorical and symbolic meaning from scenario is how to apply into set design also, mentions the method that designer multiply considers character, property and composition from the camera and movement from those elements. Set designers for animation should have ability that simultaneously considers so many elements and they need design skills to create it.

Assessing the energy performance of supertall buildings often does not consider variations in energy consumption due to the change of environmental conditions such as temperature, pressure, and wind speed associated with differing elevations. Some modelers account for these changing conditions by using a conventional temperature lapse rate, but not many studies confirm to the appropriateness of applying it to tall buildings. This paper presents and discusses simulated annual energy consumption results from a 600 m tall skyscraper floor plate located in Dubai, UAE, assessed using ground level weather data, a conventional temperature lapse rate of $6.5^{\circ}C/km$, and more accurate simulated 600 m weather data. A typical office floorplate, with ASHRAE 90.1-2010 standards and systems applied, was evaluated using the EnergyPlus engine through the OpenStudio graphical user interface. The results presented in this paper indicate that by using ground level weather data, energy consumption at the top of the building can be overestimated by upwards of 4%. Furthermore, by only using a lapse rate, heating energy is overestimated by up to 96% due to local weather phenomenon such as temperature inversion, which can only be conveyed using simulated weather data. In addition, sizing and energy consumption of fans, which are dependent both on wind and atmospheric pressure, are not accurately captured using a temperature lapse rate. These results show that that it is important, with the ever increasing construction of supertall buildings, to be able to account for variations in climatic conditions along the height of the building. Adequately modeling these conditions using simulated weather data will help designers and engineers correctly size mechanical systems, potentially decreasing overall building energy consumption, and ensuring that these systems are able to provide the necessary indoor conditions to maintain occupant comfort levels.
