In this study, we design an optimized Graphics Processing Unit (GPU)-based GNSS signal processing technique with the goal of designing and implementing a GNSS Software Defined Receiver (SDR) that can operate in real time all-in-view mode under multi-constellation and multi-frequency signal environment. In the proposed structure the correlators of the existing GNSS SDR are processed by the GPU. We designed a memory structure and processing method that can minimize memory access bottlenecks and optimize the GPU memory resource distribution. The designed GNSS SDR can select and operate only the desired GNSS or desired satellite signals by user input. Also, parameters such as the number of quantization bits, sampling rate, and number of signal tracking arms can be selected. The computing capability of the designed GPU-based GNSS SDR was evaluated and it was confirmed that up to 2400 channels can be processed in real time. As a result, the GPU-based GNSS SDR has sufficient performance to operate in real-time all-in-view mode. In future studies, it will be used for more diverse GNSS signal processing and will be applied to multipath effect analysis using more tracking arms.

In this paper, we present a primitive system design of a super multi-view(SMV) 3-D display system based on a focused light array(FLA) concept using reflective vibrating scanner array(ViSA). The parallel beam scanning using a vibrating scanner array is performed by moving left and right an array of curvature-compensated mirrors or diamond-ruled reflective grating attached to a vibrating membrane. The parallel laser beam scanner array can replace the polygon mirror scanner which has been used in the SMV 3-D display system based on the focused light array(FLA) concept proposed by Kajiki at TAO(Telecommunications) Advancement Organization). The proposed system has great advantages in the sense that it requires neither huge imaging optics nor mechanical scanning pals. Some mathematical analyses and fundamental limitations of the proposed system are presented. The proposed vibrating scanner array, after some modifications and refinements, may replace polygon mirror-based scanners in the near future.

Due to the development of science and technology and the emergence of new industries, the environmental change of the digital contents industry is rapidly progressing. The scope of technological development in the digital contents industry is affecting not only the entertainment industry but also various industries. Recently, with the development of digital convergence using realistic content, games, video, and VR have provided new opportunities for the growth of the content industry. The researcher determined that a new education system would need to be changed as the digital contents industry developed. For this purpose, an AHP questionnaire was conducted for experts with a high basic understanding of the education platform based on previous studies. We proposed a platform model for human resource development as an education system that meets the demand of digital contents industry. The education system for nurturing talents needed by future society should include elements that can interest the learning of users. The platform should not be approached from a system point of view, but should be developed from the content and user's point of view, considering the platform's original purpose.

The study explores, by carrying out literature review (theoretical pursuit) and case analysis (practical works), the changed point of view on the European war memorial/museum, the revolution of museography and its paradigm, the case analysis of war memorial/museum in the paradigm shift, the new point of view and its role. Through the theoretical thinking and the case analysis, it concludes that the exhibition space of war memorial/museum, which is in the center of material culture, is turning into the venue of societal culture. Ultimately, it aims at indicating the necessity of the paradigm shift, and offering the exhibition design strategy and technique which can better display the objects - remains - of the terrible war and the importance of peace for the old generation and the future generation.

In this paper, requirements of Meteorological Administration about Meteorological Imager (MI) of Communications, Ocean and Meteorological Satellite (COMS) is analyzed for the design of COMS ground station and according to the analysis results, the distribution image size of each observation area suitable for satellite Field Of View (FOV) stated at the requirements of meteorological administration is determined and the precise satellite FOV and the size of distribution image is calculated on the basis of the image size of the determined observation area. The results in this paper were applied to the detailed design for COMS ground station and also are expected to be used for the future observation scheduling and the scheduling of distribution of user data.

The study aims at looking, into conceptual transfer of environment between Minimal Art and Minimalism architecture and analysing architectural expressional characteristics which could visually show pro-environmental expression from concept of environment-orientation in the architecture in regional minimalism. This study issued the survey of Minimalism architecture as newly architectural trend since Late-Modernism, and pro-environment as important paradigm in the near future. In this analyses, the characteristics of pro-environmental expression can be classified as follow ; a the brightness and darkness of light, b. the perspective view of simplified wall, c. the visualization of environmental characteristics, d. the transparency and reflectiveness of glass, e. the all direction of cube, f. the visual division of architecture. These show that symbolized variety implying expression variety and implying Oriental view of nature were expressed as unique language of regional Minimalism architecture, by visual simplicity as characteristics of Minimalism and Occidental Modernism as motive of Minimalism.

This research was developed to investigate the apprehension of the ideal image of science teacher and the view of science teaching profession. The samples were drawn from middle/high schools students, university students of colleges of education, science teachers of secondary schools. principals of middle schools and masters of high schools, and professors majoring in science and/or science education. Data were collected through the use of questionaires. The samples responded differently to the Questions depending on their personal needs and professional viewpoints. Very few of the students wanted to be a science teacher in the future. Even the many numbers of college students gave up becoming a science teacher. Furthermore greater portion of science teachers were not satisfied with their profession as science teaching. More findings are described in the paper.

The organization of modern society is suddenly changing from the modern society to the ultra modern informationalized society. Various social members must satisfy cultural and artistic desires to serve museum concept and function to move the informationalized society. A lot of natural history museum in the world build cyber space exhibition lines. Audiences do not directly visit but they view but they view the exhibit, get an education, participate in the cultrue programs and earn the museum's informations. Especially, in the case of national and public museums in Korea, they do not concerned the museum architecture before processing the character and collections of the museum. Cyber museums determine museum character, policy, information, collections converge of opinion voluntary collection and grasp of location, because cyber museum can be finished be4fore the work of the future museum.

The mobile-phone which Camera was put on was released at the end of 2000 and dramatically puts up the deployment ratio because not only simple Camera but also a function that the photograph which I took is dispatched was added. It is the force that demand in this year presses 600,000,000 sale of a mobile-phone is estimated to be 960,000,000 of them in 2006, and to be able to include two errands with a support model after 3G. A person of entry to a camera-module appear much. In addition, the various kinds of products open markedly which a product comes to be known widely in the world, and the application range has opened widely, and considered QCDT come to be key issues for answer to market demand. By manufacturing industry, there is peculiar culture to each industry, camera-module is the composition the various industries. The construction of true Supply-chain becomes unavoidable to make a good product. I describe the point that the situation of each supply-chain and the direction for the future by the view point of module assembly maker.
