We have researched a character of BIM(Building Information Modeling) and GIS(Geographic Information System) data for integrated utilization of urban spatial data and building data for $CO_2$ reduction. We consider literature on integrated utilization of BIM and GIS and measure method of $CO_2$ in urban spatial unit. Among them without distortion of standard data structure, derive method how to install between BIM and GIS standard data. Rhino & Grasshopper is utilization tools of DB platform. The compatibility with existing BIM and GIS data format, graphic and numeric results can be output at the same time. And using the existing ARCHSIM, it can be easily combined for building energy analysis program. Based on BIM and GIS data to run an energy analysis target on Majang-dong, it could be poly synthetically derived the value information and graphic information.

The demands for the development of large scale software systems are being increased. Various software development methods have been introduced to meet these demands. The unit size of the codes that are reused is increasing in the development methods. These units reflect the concept of software reusability and can be identified as the object, component, and module. Recent trend in the development or a large scale software systems treats a commercial program as a unit to be reused. This approach lies along the same line as the identification of above three types of units. This paper shows how the above four types of units for enhancing the software reusability can be applied to the development of automatic graphic drawing System for a metal production.

In this paper, it is designed a processor using embedded system so that moving picture can be expressed on LED electric sign board which has been expressed a simple message only like as a character or graphic. It has been fabricated a moving picture LED electric sign board which is composed to a video processor and LED display panel, in order to be able to express a digital moving picture of 24 bits that is transmitted from embedded system. It includes gamma adjustment, brightness, color contrast control, a schedule function, expression image conversion by the Internet and memory device. Also, an application program based Windows CE is designed so that a character, graphic, and moving picture can be expressed on a small LED electric sign board.

Interest and desire for analogue emotion increased with the dazzling development of digital technology. Especially, as analogue emotion got grafted in the design field, analysis through various expression media is being done. This study seeks to propose design of t-shirt using unique advantage of Hangeul calligraphy that can satisfy the modern flow and pattern design's various expressions. Calligraphy is being used in various fields such as advert, package, logo, movie poster, signboard, graphic design, calligraphy and abstract painting. Formative yet effective in readability and conveying meaning as it's expressed in letters, calligraphy is a field of attention with its contribution in extending the new design area. As a method of the study, altogether 8 pieces of t-shirts were proposed through related preceding research, literary research, co-work with calligraphy author, computer graphic program, and heat transfer. As such, the t-shirt designs which were created by suggesting various design and using traditional materials like calligraphy, can be used as novel and sensual factor, where one can get a glimpse at the potential of development as traditional fashion product.

Character graphic design of TV screen, the major visual element, has become greatly important in its roles to help viewers understand visual information better and to enhance the qualities of the program. This research is to figure our a way of changing and improving the attributes of TV captions and graphics such as fonts, size, and caption speed appropriate to bigger and better qualified TV screen. Based on two Delphi surveys of graphics experts along with the theoretical studies, this article analyzes the relevance of visual perception to various visual elements of TV screen, and proposes a better plan in visual effects for various media under OSMU (One Source Multi Use).

This paper develops the piece creation of Hull-structure using PC(Personal Computer) which is from CADRA of graphic program. Large-sized shipbuilding yard was carried out on the development of CNC(Computer Numerical Control) auto cutting system used in super S/W such as AUTODEF, TRIBON. But this system needs lots of expenses and high technician, and only used in large-sized shipbuilding yard, not medium-sized and small-sized shipbuilding yard. To bring up the small and medium-sized ship building yard lacking a little competitive power. Small and medium-sized shipbuilding yard need the piece creation of Hull Structure S/W which is joined with the CADRA. Therefore the piece creation of Hull-Structure S/W is developed to joined with the CADRA of graphic S/W to create the piece to be needed on as auto cutting process using PC.

It is difficult to run 3D graphics based application on the embedded system with hardware constraints. Therefore, such a system must have a systematic infrastructure which can process various operations with respect to 3D graphics through any graphic acceleration module. In this paper, we present a method to implement 3D graphics acceleration device driver on Tiny X platform which provide an open source graphics windowing environment. The proposed method is to initialize the driver step by step so that the direct rendering infrastructure can use it properly. Moreover, we evaluated overall 3D graphics performance of an implemented driver through a simple but effective benchmark program.

As a preliminary step to build a complete superyacht hull design program, the development of superyacht profile design system is introduced. The two-dimensional hull profile is decomposed into four local zones depending upon the functionality and connecting continuity of the profile. Characteristics of each zone are investigated and used to generate the model describing the geometric shape of zone using freeform curves. A set of design parameters is derived from the established geometric model. Generation and modification of a model are is by manipulating the chosen parameters. Four zones designed are integrated to form a final profile. An interactive design system performing all the modeling and modification processes is implemented using the graphic user interface system based an Microsoft Foundation Class and OpenCASCADE, a open graphic library. The shapes of the profiles generated by the developed design system are verified with those of built superyachts. The developed design system will be used for the construction of three-dimensional superyacht hull modeling system.

The graphic processor unit (GPU) has been developed to process not only graphic data but also general system data. It shows a better performance than CPU in algorithm for 3D graphics and parallel program. In order to execute algorithm for CPU on GPU, we should understand about GPU architectures and rewrite program considering parallel processing capability and new memory model of GPU. For this reasons, a performance prediction model for the algorithm and its predicted performance through GPU system are required. These can predict problems in GPU application development or construct a performance evaluation standard for GPU. In this paper, we applied the AES encryption algorithms on our performance model and accomplished performance prediction with high accuracy under a heavy workload.
