RFID is an emerging technology and rapidly applied to various industries due to its high-tech characteristic and convenience. Although RFID provides valuable benefits. it might also generate serious privacy problems. Previous studies show that privacy issues should be incorporated in developing RFID systems and more detailed privacy protection methods. However. they just provide basic concept, rough guideline. and simple architecture about RFID privacy protection. Industry needs more structured framework and detailed systematic process to incorporate privacy issues into the RFID system. The purpose of this paper is to develop a framework and detailed process design of RFID privacy protection issues in retail industries. A framework is developed based on individual sensitivity concept, RFID contents, and interface with EPC global standard. Case study is applied to validate the framework and it turns out to be useful. It is expected that the proposed framework and process design would provide more systematic guide lines to solving RFID privacy problems.

The educational contents could be better off when the visualization, personalized storytelling and interaction are combined and fused in the interface. In this paper, we analyze the specification of I/O cooperation based on MS agent framework. which can be applied to the development of educational contents.

In MPEG-21 Multimedia Framework, Digital Item (DI) is the minimum unit fur processing and delivering the multimedia contents. So how to process, manipulate and represent DI is a very important problem in the standpoint of interoperability for each terminal and provide., and Digital Item Processing (DIP) regarding this issue. This paper suggests technologies which are concerning how DIP should interact with other parts of MPEG-21 (Digital Item Adaptation (DIA), Intellectual Property Management and Protection (IPMP), etc.). For this concept, this paper uses the video summary contents which can describe the hierarchical structures of original multimedia contents. In MPEG-21 environment, the usage of this summary video is very useful delivery and consumption way in view of network burden, efficient accessing to contents.

All records have attribute of representing the object, so archives should develop digital record exhibition to facilitate attribute that representing the object. If building cultural properties are chose as the represented object, it should be followed by analysis of nature values and record contents and applied to the suitable framework. Therefore, this study suggests the organized process of designing the framework which develops digital representing contents based on records.

Recent IPTV services still remain as simple broadcasting services that cannot make the most of interactive features together with various content-associated data. So, IPTV providers are making efforts to break from monopolistic style, so as increasing the user's participation m service. However there is an interoperability problem because no common solution is employed across different providers. To solve this problem, there needs to be a framework for a framework for generating, sharing and distributing package contents. In this paper, we propose user-centered package contents application framework for interactive IPTV services. We also design a package content authoring and consuming system which plays core parts in the proposed framework.

We have fabricated the supercapacitor composed of porous activated carbon, metal-organic framework (MOF) with polymer based solid state electrolyte as a "ion gel" and characterized its electrochemical behaviour as a function of the MOF contents. The electrochemical properties of the supercapacitor were analyzed via cyclic voltammetry(CV), electrochemical impedance spectroscopy(EIS) and galvanostatic charge/discharge test. As a results, the supercapacitor based on porous activated carbon/MOF composite showed the highest capacitance value at 0.5 wt% of MOF contents and decreased capacitance with increase MOF contents over the 0.5 wt%. Consequently, the porous activated carbon/MOF composite based supercapacitor is applicable to various aspect for energy storage device.

As cellular network technologies continue to evolve, various network standards coexist in most CDMA-based cellular networks. This means that mobile device users access mobile services over different network bandwidths according to the users' positions or the mobile devices' network access capabilities. Such differences of network bandwidths cause big differences in service response times. To address this problem, we present a framework called CANS (Context-Aware framework for mobile Navigation Services), which takes into account the user's network profile to adapt the contents for CDRG(Centrally Determined Route Guidance) navigation services for cellular phones. To the best of the authors' knowledge, CANS is the first context-aware framework to make mobile navigation services more feasible. The experimental results under commercial CDMA network show that CANS is able to provide similar service response times regardless of type of wireless network to which users connect by adapting the contents to network bandwidths.

Smart TV has been the most popular communication device since 2010. It is the multi-functional device conjugated a variety of features such as Apps, Web surfing, viewing VOD and so on. However, the contents and development tools for smart TV are still relatively small and research for game contents development tools is also insufficient. In this study, we are to design and develop a framework for developers to make Smart TV game contents easily. The STGF (Smart TV Game Framework) we developed is made up of 3 managers such as input manager, screen data process manager, and game status process manager. We verified the usefulness of STGF through developing "Pentomiro" App launched commercially in 2013. With STGF development time would be expected to be reduced, because we spend little time in basic development steps such as input, output, and data processing and error correction processing.
