The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studios middle school textbooks. Data were collected through national curriculum documents and social studies middle textbooks for 7-9 grades. We set up three questions for this studies; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) Photographs, illustrations, information maps, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, circle graphs, and stripe graphs nip often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not so good, especially in the curriculum steps of information mads scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics are needed for social studies teachers.

In the field of computer graphics, rendering speed is one of the most important factors. Contemporary rendering is performed using 3D graphics systems with windowing system support. Since typical graphics systems, including OpenGL and the DirectX library, focus on the variety of graphics rendering features, the rendering process itself consists of many complicated operations. In contrast, early computer systems used direct manipulation of computer graphics hardware, and achieved simple and efficient graphics handling operations. We suggest an alternative method of accelerated 2D and 3D graphics output, based on directly accessing modern GPU hardware using the direct rendering manager (DRM) system. On the basis of this DRM support, we exchange the graphics instructions and graphics data directly, and achieve better performance than full 3D graphics systems. We present a prototype system for providing a set of simple 2D and 3D graphics primitives. Experimental results and their screen shots are included.

The purpose of this qualitative case study is to understand how the idea of data view and information graphics is used in the social studies high school textbooks. Data were collected through national curriculum documents and social studies middle school textbooks for the 10th grade students. We set up three questions for this study; what kinds of information graphics are used in the textbooks, how the graphics are organized in the social studies middle school, and how the 7th social studies curriculum is related with the 7th national mathematics curriculum. Through the data analysis, we found that 1) photographs, information tables, illustrations, etc., are used and frequencies of their usages are in descending order, 2) double lines graphs, and stripe graphs are often adopted for the comparison of populations, 3) the relation of the two subjects curricula is not well developed, especially in the curriculum steps of information maps, scatter diagrams, and comparison of populations. Finally we suggest that new web site of data view or information graphics be provided for two curricula, workshop of information graphics be needed for social studies teachers, and modification of the 7th probability and statistics curriculum.

The statistical graphics is a design field focusing on the user perception aspects for the correct information delivery and the effective understanding, with the use of the quantitative data through the information analysis, extraction, visualization process. The statistical graphics with the big data composition factor is termed as the statistical big data graphics. In the statistical graphics the visual factors are used to reduce the errors in the perception part and to successfully deliver the information. However, in the statistical big data graphics the visual factors of the enormous data are causing the cognitive discouragements. The purpose of this study is to extract the cognitive discouragement factors from the big data statistical graphics, categorizing the types of the statistical big data graphics as 'network type', 'segment type', and 'mixed type', based on their compositional shapes, and explored the characteristics according to them. Especially, based on the visual main factors in the statistical big data graphics, We extracted the cognitive discouragement factors that appear in the high visualization as the four categories: 'multi-dimensional cases', 'various color', 'information overlap', and 'legibility of the writing'.

In this paper, we propose the hardware architecture to accelerate 2D Vector graphics process for mobile devices. we propose the Transformation Unit Architecture that considerates the operation dependency. It has 3 cycles excution time and uses 2 multipliers and 2 adders. Proposed paint generation unit uses a LUT method, so it does not execute color interpolation which needs to be calculated every time. The proposed OpenVG 1.0 Accelerator achieved a 2.85 times faster performance in a tiger model.

The purposes of this paper are to review the concept and system structure of computer graphics and to discuss the applicability of computer graphics technique as an analysis tool in transportation studies. To do this, several applications of computer graphics used for analyzing and solving transportation system problems were described and illustrated. The results indicate that computer graphics are found to be powerful aids to the analysis and design of transportation systems that typically involve large data bases and several interacting components. The results also indicate that computer graphics can be a powerful tool for aiding planner, decision maker and citizen in making it easier to explain and interpret information through mapping and graphic display.

본 논문은 3D 스캐너 및 센서 등으로 캡처되어 3D로 복원된 얼굴 객체의 부위별 의미 있는 영역에 대한 분할을 자동으로 수행하는 기술을 제안한다. 3D 스캔된 얼굴 모델을 모델링, 애니메이션, 3D 프린팅 등의 다양한 응용분야에 활용하기 위해서는 스캔된 영역의 의미 있는 부위별 인식이 필수적이다. 본 논문에서는 부위별 의미 있는 영역 레이블링이 된 템플릿 모델을 입력된 3D 복원 모델로 전이하여 복원된 3D 모델의 부위별 의미 있는 영역을 자동으로 분할하고 분할된 영역의 일관성을 유지하는 알고리즘을 제안한다.

Today, newspapers and newsmagazines are using statistical graphics to provide information and highlight the essense of newspaper stories. When statistical graphics do not present meaningful information accurately, concisely, and in easy-to-understand language, the publication risks a loss of credibility with its readers. Too often newspapers and newsmagazine run faulty graphics. The surge in the use of statistical graphics have created new problems and challengers for editors and artists of newspapers and magazines. We summerize and study the misuse of statistical graphics by means of the research of newspaper and newsmagazine. Experiments were employed to explore the effects of the distorted graphs. This paper suggests the statistical rules for avoiding the pitfalls of statistical graphics and institutional solutions for reforming the knowledge of artists and readers about statistical graphics.

Due to rapid development of mobile communication terminals and various requests of their users, multimedia information including image information has been the basis of mobile communication contents. In order to use vectored image information efficiently, which is more favorable than bit-mapped image information when transmission delay time and costs are considered, efficient vector graphics supporting systems are needed. Therefore, vector graphics kernel systems have been proposed and standardization attempts have been made in order to increase interoperability. In this paper, a vector graphics kernel based on OpenVG is designed and implemented. OpenVG was proposed as a standard vector graphics kernel by Khronos Group recently. The implemented vector graphics kernel, named by alexVG, is developed on a PC emulator as well as on a development board equipped with an ARM processor. In addition, performance tests are made in order to verify its functions.
