In this paper, we propose a design method for the construction of LTE-based small unmanned aerial vehicle control system to quickly and reliably collect multiple small unmanned aerial vehicle position information simultaneously flying all over the country. In particular, the main requirements are the network (N/W), hardware (H/ W), software(SW), Database(DB), development architecture, and business needs. To satisfy these requirements, N/W, H/W, SW, DB design, and architectural design plan were suggested regarding the design requirements of a small UAV system. To effectively control the small unmanned multi-party system in the system design, the architecture is divided into the front-end service area and the back-end service area according to the function and role of the unit system. In the front-end service area that grasps and controls the position and state of small unmanned aerial vehicles (UAVs), we have studied the design part that can be expanded to N through TCP/IP network by applying Client PC method.

The role of digital content identification system is being considered as a useful solution for the content management system and service system. Integrated Copyright Number(ICN), only one domestic identifier to the managing of copyright, can provide the service model in the copyright industry, because it include the information of copyright between the creator and the service provider on the digital work. Universal Content Identifier(UCI), has developed on the focus of digital content service, is somewhat lacking on the copyright management, but it is expected that systematical management and distribution system for copyright and digital work to be able to build as that make up for disadvantage with each identifier's advantage by UCI associate with ICN. In this context, This article can suggest the efficiency integrated structure and the service scenario. Therefore it is contribute to the efficient using and the effective running in the digital identification system.

The conventional assistive tool for visually impaired people provide Simple service using a ultrasound, or an RFID tag to identify the obstacles. It is impossible to clear guide and has a vulnerability to unforeseen circumstances because of short recognition distance, The ARM Cortex-A9 Platform based implementation of the Portable Navigation System and Service Center will help the visually impaired gait. The Service Center will also provide solution for the lack of jobs due to the increase of the aging population. Navigation System that the visually impaired can carry possessing devices such as a camera, GPS, Audio, Ethernet transmit Image shown at the location of the visually impaired, GPS information and Sound Via TCP / IP. The staff of the service center receives information and can provide directions by communicating with them. So, the system can provide effective guidance to the visually impaired.

As recent developing computing environments, service is provided without time or place's limitation, and it is constituted dynamically. Above all, in terms of education supporting system, there is need to conceive user's information and provide optimal service as to right with applying context awareness under Ubiquitous computing environment. It should have groundwork based on user location and time. It is requires service providing based on user location under the condition of class to offer appropriate service with the context. In addition, context information providing technology is needed to offer right education support service in the class, where are different context information. Hence, in this research it is suggested education supporting system to provide context-based for instructor. The framework of this system has a foundation within previous work about Multi-agent based Distributed Framework. To examine implementation of context-based education supporting system in Ubiquitous computing environments suggested by this report, arranging system can fit information relates to instructor's location for service applying in the class.

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 range of Internet usage is drastically broadened and diversed from information retrieval and collection to many different functions. Contrasting to the increase of Internet use, the efficiency of finding necessary information is decreased. Therefore, the need of information system which provides customized information is emerged. Our research proposes Web Service based recommendation system which employes inference engine to find and recommend the most appropriate products for users. Web applications in present provide useful information for users while they still carry the problem of overcoming different platforms and distributed computing environment. The need of standardized and systematic approach is necessary for easier communication and coherent system development through heterogeneous environments. Web Service is programming language independent and improves interoperability by describing, deploying, and executing modularized applications through network. The paper focuses on developing Web Service based recommendation system which will provide benchmarks of Web Service realization. It is done by integrating inference engine where the dynamics of information and user preferences are taken into account.

Since different methods or protocols have been used to manage various mobile terminals, it has been difficult to manage mobile terminals efficiently. OMA(Open Mobile Alliance), therefore, proposed OMA DM(Device Management) as a standard for device management. In this paper, in an effort to apply the OMA DM concept ta real application area a home-delivery service management system using OMA DM agents is designed and implemented. The home-delivery service management system is developed using SyncML Tool Kit 4.3, SK WIPI SDK and Embedded Visual-C++ under the environment of SK-WIPI Clet. Since the home-delivery service management system is developed using OMA DD which is expected to be installed in most of the mobile terminals, separate lower level program modules for the management system would not be necessary. In order to justify this world some experiments are performed using SK WIPI emulator 1.1., which provides the same execution environments as a real mobile terminals does. Experiments show that the home-delivery service management system developed in this paper, works properly.

In this paper, a new interactive TV service model is proposed. The MPEG-4 system is specified for composing and managing various object streams including user interactions. The data broadcasting model supporting user interactions is designed using MPEG-4 system in our proposal. We evaluate possibility of proposed service model using simulation player. This player supports MPEG-2 TS which contains MPEG-2 video and AC-3 audio streams as a main service and MPEC-4 system data as interactive services as well as user specific EPG information, and XML data, etc as supplemetary services. The player also supports a multi-channel environment. The synchronization between audio and visual data is achieved by DTS and PTS in TS.
