On the threshold of year 2000, the elderly account for more than 7% of the whole population in Korea, which means that the nation is greeting welcoming an aging society. Accordingly, it is expected that silver businesses and services targeted at the silver generation will prosper with "silver advertising design" becoming active. Under such circumstances, this study was aimed at reviewing the recent silver marketing advertisements in terms of their cultural and moral implications, and thereby, redefining and reestablishing the status of silver consumers to help them find their identity, aware of marketing activities and therewith, establish their "consumer sovereignty". This study consists in large of 5 chapters. The introduction parr describes background, purpose, method and scope of the study. The first chapter reviews the silver marketing theories. The second chapter classifies the silver marketing advertisement positioning of four style - upper classes style, effloresce progress style, self- sufficiency style, dependent style - and reviews the expression strategy of each positioning. The third chapter examines the domestic conditions of silver marketing advertisements for each positioning type classified. The fourth chapter designs the ′creative′of silver marketing advertisements and suggests the methods thereof. The analysis of ′creative′was tested in terms of graphic gestaltung, and how the sliver marketing advertisement positioning should be discerned depending on silver generation consumer′s characteristics was discussed. The fifth chapter puts forwards the suggestions for the ′creative′ strategies to enhance the effects of the silver marketing advertisements, based on the preceding discussions. In addition, the Perspective into the keyword of 21 st century or "silver design" is discussed, together with the limitations of this study. It is hoped that this stuffy will be conducive to our efforts to face the upcoming′age\ulcorner society′more effectively. To this end, this study discusses the "silver advertising design" in light of ′societal concepts′and ′customer-oriented value′, and thus, explores some creative presentation strategies whereby individual companies interests and social or public interests can be compromised through ′creative activities′ and ′equal-value consumerism′ for an ultimately effective management strategies for silver businesses and services.

Leading educational paradigm based on Constructivism drives for many changes in the field of education. It causes the shift from instructor-based to learner-based learning, and cooperative teaming amongst the learners. Multi User Game (MUG) which is a network-based cooperative game is popular among many college students. MUG is known to provide positive and creative activities encouraging learners to participate, reform and produce new knowledge and skills. Thus, it has potential as an effective learning tool. In this study, however, we have designed a prototype of Cooperative MUG Game for elementary students to learn within networked environment to play while learning new knowledge and skills. The elementary students will interact with the other students through chatting while playing MUG.

The flight control law of developed flight control computer(DFLCC) is developed based on operation flight program of advanced trainer aircraft full scale development final configuration. The flight control law design is used common use development tool in GUI(Graphic User Interface) environment. The flight control law transformed to C-Code is reflected in OFP. The OFP is verified by the standardized verification process. But, before standardized verification process, we need preliminary verification process such as similarity of flight control law and reliability of developed HILS. Similarity of flight control law is verified by comparing the aircraft response of advanced trainer aircraft and those of the developed control law. Also, reliability of developed HILS is verified by comparing the aircraft response of HILS and Non-real time simulation result. This paper verifies similarity of developed control law and reliability of HILS environment as comparing aircraft response.

The study of application using multimedia contents have been worked out a lot. But those trial can be hardly to be applied because each social study curriculum has a little difference which is a peculiar properties in social study. So we try to find the most efficient study method making multimedia contents system with computer graphic design and animation and sound and movie. This study introduce the method of image transcoding in real time based on repurposing structure to make better use of a multimedia contents system. We assume that developed multimedia contents system could be a big help to increase study efficiency through graphic, sound, movie as well as to encourage student's motive and interest. It is mostly possible to use for creative, self-controlled and social study material which is used to study the subject with conversational and repetitive way. So we hope this study will be a good guide line of developing various contents in multimedia contents.

Because worldwide interest in the health is increased, the real-time health monitoring system has been demanded to be more convenient non-contact and precise medical devices than conventional. Therefore we developed the blood pressure monitoring system using UWB(Ultra Wide Band) radio wave which contact to the human body through the radar and continuously collect a movement signal of the blood vessel. Then the collected data including pulse rate, systolic blood pressure, diastolic blood pressure is processed in real time. The system monitors and controls through a program-based embedded LCD(Liquid Crystal Display) using Qt GUI(Graphic User Interface) to be displayed in real time. We implement the system as a embedded system because of reducing the size of the limited resources. Existing PC GUI design mode is used relatively large memory, therefore it requires more CPU(Central Processing Unit) capacity and processing time.

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).

We propose hardware architecture of floating-point square root and inverse square root arithmetic units using lookup tables. They are used for lighting engines and shader processor for 3D graphic processing. The architecture is based on Taylor series expansion and consists of lookup tables and correction units so that the size of look-up tables are reduced. It can be applied to 32 bit floating point formats of IEEE-754 and reduced 24 bit floating point formats. The square root and inverse square root arithmetic units for 32 bit and 24 bit floating format number are designed as the proposed architecture. They can operation in a single cycle, and satisfy the precision of $10^{-5}$ required by OpenGL 1.x ES. They are designed using Verilog-HDL and the RTL codes are verified using an FPGA.

In this paper, we present a haptic virtual exhibition space that allows users to interact with 3D graphic objects not only through the sense of sight but also through the sense of touch. The haptic virtual exhibition space offers users in different places some efficient ways to experience the exhibitions of a virtual musical museum using the basic human senses of perception, such as vision, audition, and touch. Depending on 3D graphic objects, we apply different properties to let those feel realistic. We also provide haptic device based navigation which prevents users from rushing between various interfaces: keyboard and mouse. The haptic virtual museum is based on Client-Server architecture and clients are represented in the 3D space in the form of avatars. In this paper, we mainly discuss the design of the haptic virtual exhibition space in detail and in the end, we provide performance analysis in comparison to other similar applications such as QTVR and VRML).

As the mobile computers such as Personal Digital Assistants (PDAs) or Smart Phone has been widespread in our daily life, the demand of an extensive data input will gradually be increased. Consequently, many alternative soft keyboards have been proposed to satisfy this requirement. However none of them can provide an absolute solutions for that, the segregated guideline for keyboard arrangement and usage still cause much confusion to the user. Therefore, an integrated guideline is seriously required. In order to come up with the integrated guideline for Korean Soft keyboard GUI, the questionnaire and the experimental test compared with five soft keyboards were conducted in this study. As a result this paper presents five guidelines for improving an input speed of soft keyboard on the mobile computing; following familiarity for effective screen use, using a single key rather than grouping key, considering position of prediction word, considering prompt feedback, finally, considering optimized keyboard size.
