The idea of displaying hologram electronically has been existed since mid $1960^{th}$. But it is still in the beginning stage due to the lacks of proper means of displaying and recording, which will bear the large amount of data contained in the hologram though holographic video and digital holography have demonstrated the possibility of displaying and photographing hologram electronically. It is expected that holography based 3 dimensional imaging system will be introduced much later than that on multiview 3 dimensional imaging methods which are being developed to generate more realistic and natural image than high definition plane images.

The robustness of communication service should be guaranteed to validate its security of the whole service not just high performance. One kind of practical test-beds is the chinese communication service based on SIM Card and GSM. In paper, we try to experiment the possibility of SIM cards clone in various mobile communications using 2G in china, and hence discovered the security vulnerabilities such as the incoming outgoing, SMS service and additional services on the mobile phones using clone SIM cards. The experiments show that chinese communication service should be prepared the Fraud Management System against the cloning SIM card. and furthermore, regulations related to the communication service should be tuned the realistic security environments.

In this paper we propose an emotional expression method using a comic model and special marks for effective sign-language communications. Until now we have investigated to produce more realistic facial and emotional expression. When representing only emotional expression, however, a comic expression could be better than the real picture of a face. The comic face is a comic-style expression model in which almost components except the necessary parts like eyebrows, eyes, nose and mouth are discarded. In the comic model, we can use some special marks for the purpose of emphasizing various emotions. We represent emotional expression using Action Units(AU) of Facial Action Coding System(FACS) and define Special Unit(SU) for emphasizing the emotions. Experimental results show a possibility that the proposed method could be used efficiently for sign-language image communications.

This paper proposes the possibility of SonicID system which is the active RFID based on the ultrasonic spectrum instead of using radio frequency. For the feasibility study, various performance indexes are measured in terms of power consumption and signal path loss onto the frequencies of 40KHz, 433MHz, and 2.4GHz. In addition to the line of sight condition, realistic situations are considered for diverse deploying environments. The results of these analyses demonstrate that the SonicID holds the potential to meet the needs of future advanced RFID system in a scalable fashion.

In recent years, many studies on the public library services for individual vulnerable groups have been performed in Korea. From the standpoint of public libraries with limited human and physical resources, however, all proposed alternatives are difficult to accommodate due to overload and in an integrated perspective, the several alternatives have a logical contradiction and possibility of realistic conflicts. Focusing on these facts, this study proposed an integrated direction and strategic plan to strengthen knowledge and information services of public libraries for five vulnerable classes, ie., the disabled persons, multi-cultural families, the elderly, rural residents, basic living subsidies.

Two-page spread sheet advertising appearing on monthly women's magazine were selected and analyzed for this study. All 299 advertisements were sampled from 5 kinds of women's magazines published from January to June in 2002. The results shows that; 1) all elements of layout in advertisements are significantly related to product life cycle; 2) Similarity of layout type proposed to differentiate layout from competitor's advertisements; 3) Realistic picture of products using high technological equipments and skill occupied most of ad space. It proposed the possibility of varied illustration type; finally, Using foreign models both imported products and domestic products are increased. It shows that the level of westernized insight of current consumer.

Since Universal Design emerged as a new design paradigm for future, the strategies of implementing UD in educational setting has been continuously pursued. Many university programs in North America especially explored the possibility and shared their experiences in the international conferences. In asia, however, no attempt was tried. This presentation will share the navigation teaching modules used in a undergraduate course “Interior Environment and Human Behavior” class, its methodology of experience and data analysis, and finally educational outcome. Since UD is a basic human oriented design, the modules surely provided affluent and realistic opportunity for students to feel emotional sympathy to understand a diverse range of users and to facilitate creative design solution for them.

As energy related problems continue to arise, Korea's thermal insulation market for the zero energy homes is also demanding major changes, but there are no realistic countermeasures. Also, interest in inorganic insulation is growing as damage from multifamily housing fire using flammable insulation materials is increasing. On the other hand, many studies have been conducted on lightweight foam concrete, which implies a sufficient possibility as an insulation material by generating a large amount of air bubbles. However, studies of existion bubble concrete are not quantified by the experimental difficulty of using bubbles when compared. Therefore, in this study, the change in strength due to air pressure using a bubble foam, one of the types of air bubbles for the development of light foam concrete.

Based on current practical needs for geo-spatial information on mobile platform, the main theme of this study is a design and implementation of dynamic 3D terrain rendering system using spaceborne imagery, as a kind of texture image for photo-realistic 3D scene generation on mobile environment. Image processing and 3D graphic techniques and algorithms, such as TIN-based vertex generation with regular spacing elevation data for generating 3D terrain surface, image tiling and image-vertex texturing in order to resolve limited resource of mobile devices, were applied and implemented by using graphic pipeline of OpenGL|ES (Embedded System) API. Through this implementation and its tested results with actual data sets of DEM and satellite imagery, we demonstrated the realizable possibility and adaptation of complex typed and large sized 3D geo-spatial information in mobile devices. This prototype system can be used to mobile 3D applications with DEM and satellite imagery in near future.
