The increase in computing power and the decrease in price of computers has enabled statistical computer graphics to progress tremendously in recent years. Many people can now access to the newly developed computer graphical methods easily. The direct manipulation on screen and the symultaneous realization of the results are two main ingradients of dynamic graphics. We compare the dynamic graphical features in two relatively new packages; SPLUS and XLISP-STAT. XLISP-STAT is very lean packed with powerful dynamic graphical tools. The statistical computer graphics, being still in the state of infancy, has a lot of room to grow, and is a new research area with a great potential.

Rendering technique generating 2 dimensional image to give reality and high performance graphical processor for efficient processing of massive data are necessary to support realistic 3 dimensional graphical image. Recently, graphical hardwares have evolved rapidly. This enables high quality rendering effect that we were unable to process in realtime. Improving shading technique enabled us to render realistic images but still much time is required for this process. Multiple operational units are being integrated in a graphical processor for effective floating point operation using massive data to process almost real looking images. In this paper, we have designed and implemented a special functional unit to support high quality 3 dimensional computer graphic image on programmable integrated shader processor. We have done evaluation through functional level simulation of designed special functional unit. Hardware resource usage rate and execution speed are measured implementing directly on FPGA Virtex-4(xc4vlx200).

This study analysed motion graphic formative image composition of TV LED backdrop to be used as background display for performers such as singers appeared on TV music show. Motion graphic LED images are comprised of various plane figures, and backdrop's design function as background screen has a goal to convey synesthesia and sensibility of visual elements. And this analyse classified sensibility concept about color, motion direction and speed to be elements of transmitting sensibility. As the analyse of graphic form among transmitting sensibility elements, this classified form type into its' applied elements, and studied how these elements' motion pattern and arrangement could be placed and replaced at song's four step composition, intro, verse, bridge, chorus part, and also characterized differences of backdrop design for male and female performers. As a case study, it included terrestial broadcasting TV song ranking shows targeted at teenagers. Because they carried out various motion design utilizations. Finally, this reasoned out mainly designing form type, its' applied elements, motion pattern and its' arrangements type division according to the song developing four steps.

In the modern times, video media area is dramatically developing and growing. The motion graphic that is one of video presentation technique as an effective communication way between sender and receiver is beginning to make its appearance. The motion graphic provides the clearance of visual information to deliver it more easily and accurately and improves the effect of communication to increase the effect of image and information delivery. In this research, the writer wants to examine the production method of motion graphic to improve convenience and efficiency of communication to the better direction for production process by researching and analyzing the title design and its structure having short and significant information delivery and strong visual presentation function.

Recently, according to the increasingly populated data, many media and organizations focus on big data, data visualization, information visualization and infographics. Domestically, Chosun.com and Hankyoreh online have improved on the data visualization field and internationally, the Guardian, Wall Street Journal, and New York Times are the leading companies on that area. Until now, many people have recognized infographics as a design-oriented product in Korea. However, one of significant data visualization programs, Tableau Public, can visualize data more efficiently. In this paper, Data Visualization Methods Quadrant for Policy Making is defined, and data analysis and producing infographics are executed. As used data, World Bank open source was adopted and using the number of passenger cars per 1,000 people, two analysis results are extracted. First, in high income group, the more GNI per capita, the lesser Slope is represented and in mid income group, the more GNI per capita positively affects to Slope. Second, in the global finance crisis, the car ownership rate was about 1.7 times than the usual state in the global economy. Through the case study, this paper suggests that the direction of producing infographics should be changed from design-oriented to data-oriented. Moreover, the data-oriented infographics should be propagated as means of scientific research and policy making.

원전 디지털 계측제어시스템에서 공통원인고장(Common cause failure)의 발생 가능성이 증가함에 따라 이를 방지하기 위해 프로그래머블 논리소자(Field Programmable Gate Array)를 이용한 제어기가 개발되어 활용되고 있다. 그러나, FPGA-기반의 제어기를 구현하는데 사용되는 하드웨어 기술 언어는 그래픽 언어를 이용한 PLC 기반의 개발을 하던 대부분의 원전 계측제어 엔지니어에게 친숙하지 않아 제어기의 구현에 어려움이 있다. 따라서 엔지니어에게 친숙한 그래픽 언어를 이용하여 FPGA 용 제어 프로그램을 작성할 수 있는 통합개발환경이 필요하다. 본 논문에서 구현한 VerilogLinker 는 제어프로그램의 개발을 위한 통합개발환경의 일부로 통합개발환경을 이용한 제어 프로그램의 개발과정 중에서 생성된 Verilog 파일을 FPGA 공급자가 제공하는 상용 소프트웨어인 Libero SoC 와 연결하는 기능을 제공한다.

The compartmentation model is represented by the characteristics and geometric information of the spaces defined by the structural members which are used for the boundary planes of the compartment. For the efficient compartment modeling a program performing the compartmentation design by the chopping and merging method was presented by authors. In this research, the development of an interactive ship compartmentation modeller is introduced. It is natural that the value of the program lessens if the input process is complicated and uneasy, even though the internal techniques for the compartmentation modeling are superior. In this paper, a method for the convenient input is proposed and implemented with the help of a graphical user interface technique. The modeling method introduced in this paper performs an efficient compartmentation modeling fast and conveniently by the solid modeling concept and the graphical user interface.

Recently, there have been increased many 3 dimensional graphic applications in Internet. Thus, a growing number of methods have been proposed for retrieving 3-D graphic data using their 3D features such as color, texture, shape, and spacial relations. However, few researches focus on 3D graphic modeling and database storage techniques. In this paper, we introduce a system that can store 3D graphics data modeled by XML-based 3D graphics markup language, 3DGML, and support content-based retrievals on 3D data by using SQL. We also present a mapping technique of 3DGML to relational database. The mapping process includes the extraction of semantic information from 3DGML and translate it into relational format. Finally, we show examples of SQL queries which use the 3D information contained in a 3D scene such as objects, 3D features, descriptions and scene-object component hierarchy.

As the artificial intelligence and big data technology has been developed recently, the importance of GPGPU, which is a general purpose graphics processing unit, is emphasized. In addition, by the demand for mining equipment to obtain bit coins, which is a block chain application technology, the price of GPGPU has increased sharply with scarcity. If a GPGPU can be precisely simulated, it is possible to conduct experiments on various GPGPU types and analyze performance without purchasing expensive ones. In this paper, we investigate the configuration of a GPGPU simulator and measure the performance of various benchmark programs using GPGPU-Sim.
