The demand of digital broadcasting via networks has increased slowly in spite of the development of bidirectional broadcasting service technology and the effort of revitalization are actively performed nowadays. There are some reasons that the content differentiation is necessary. First, bidirectional digital broadcasting has no special content that attracts public attention. Second, bidirectional video content such as UCC is expected to revitalize economy due to simplification of authoring tool and user's desire to communicate interactively. So this paper proposes the data broadcasting sub-content architecture model by scenario using original data broadcasting content. At the same time, we design the content object metadata schema from the analysis of original data broadcasting content. It is restricted by 25 metadata in order to make it more smoothly working contents under the ubiquitous environment. This proposal is expected to affect the revitalization of content development and find out new sub-content model by rework original content.

In this paper, we mainly describe the development of exclusive u-device essentially required to implement new ITS services (taxi call service, service for transportation vulnerable, transport information service, walker's navigator, electronic payment service, call information service etc.). To design this device, Samsung main CPU S3C2440A was selected and large memories (ROM and RAM) which are required for new ITS services are applied. In addition, all of GPS, RFID module, Wi-Fi and Bluetooth functions are included to develop an exclusive device indispensable in the ubiquitous society. For this, in this paper, we first examined detailed design of an exclusive u-device development, and based on the designed contents, the performance of a realized u-device was evaluated. If services are created by linking new ITS services with relevant public institutions or companies, based on application of the exclusive u-device developed as above, they would be expanded to a new blue ocean, expectedly resulting in a big spillover effect in local societies.

In ubiquitous geographic information environment, the users are provided with geographic information anywhere and any time on their needs by any types of devices and communication media. The unique location ID, ePosition, is a new technology to support UBGI environment, using a logical location ID instead of physical location of a point of interest. Domain names of plural ePosition servers, where location information with its ePosition is stored, needs to be registered in DNS for some service through Internet. For better ePosition service of the type of public service like email service, a set of DNS resource records can be newly defined. This paper suggests a new DNS resource record EPO for implementation of the ePosition service through Internet.

IT Service Management (ITSM) achieves consolidated management for the IT services supporting the acquisition system, and no outside connections can be established with such ITSM. Issues pertaining to the D2B can be addressed to System Q&A or a Call Center for problem-solving. In other words, internal staff can take the necessary measures for problems by directly connecting with ITSM. Currently, diverse innovative technologies are being used in electronics and ubiquitous computing environments. This allows us to create a better world by providing the backbone for remarkable development in our human society in the fields of electronics, devices, computer science, and engineering. Following the expansion of IT services in the military acquisition sector such as Defense Electronic Procurement, military export/import support system, etc., customers' dependence on IT for conducting business with the military or related companies is increasing, including the military's dependence on the same technology for services to the public. Nonetheless, issues pertaining to the simplified/integrated management of complex IT service management systems, including slow system recovery, lack of integrated customer service window, and insufficient information sharing, have become the priority problems that IT managers are required to solve. Therefore, this study conducted research on the integrated management of IT services provided by Korea's national defense acquisition system, which was developed based on the existing system IT Infrastructure Library (ITIL) v2, and investigated the level of satisfaction with services with focus on ensuring that it can be used for understanding the necessity of the system and its advancement in the future.

The Korean government required the mandatory ratio of public housing including the housing unit for elderly in February 2012 and the number of them is expected to increase accordingly. To prepare for an aged society, these enabling ubiquitous technology will be able to support efficient health care services, which was mentioned in various studies. Therefore, the aim of this study is to draw the design elements for an apartment for providing health care services according to the degree of independence of elderly people and to grasp the current situation and work out tactics by the evaluation of four actual cases. In housing unit in the elderly housing project, design elements supporting amenity improvement was rated to the highest importance, however, in reality, was reflected at lower rate while the risk management plan for public space was applied at the highest rate. Design elements required by new technology such as health monitoring and community management with outside world are still not reflected, however, in order to realize the concept of 'aging in place', health care services in various aspects should be considered in housing planning.
