To interactively share High Definition (HD)-quality visualization over emerging ultra-high-speed network infrastructure, several lossless and low-delay real-time media (i.e., uncompressed HD video and audio) transport systems are being designed and prototyped. However, most of them still rely on expensive hardware components. As an effort to reduce the building cost of system, in this paper, we propose the integration of both transmitter and receiver machines into a single bi-directional transport system. After detailed bottleneck analysis and subsequent refinements of embedded software components, the proposed integration can provide Real-time Transport Protocol (RTP)-based bi-directional transport of uncompressed HD video and audio from a single machine. We also explain how to interface the Gbps-bandwidth display output of uncompressed HD media system to the networked tiled display of 10240 $\times$ 3200 super-high-resolution. Finally, to verify the feasibility of proposed integration, several prototype systems are built and evaluated by operating them in several different experiment scenarios.

In order to construct the IEC 61850 based substation automation system, the IED integration engineering tool is necessary to cope with the substation automation by full digital devices in the real power system. Compared the configuration tools provided IED vendors which are able to support the operation and communication analysis among IEDs, the XML based IED integration engineering tool can build, edit and save the ICD, SCL and CID files. Particularly, the IED integration engineering tool is possible to apply the IEC 61850 based IEDs to engineering the systems and also provides the reliability and efficiency of the system to the utilities and manufacturers.

Americium-beryllium (Am-Be; n, ${\gamma}$) is a neutron emitting source used in various research fields such as chemistry, physics, geology, archaeology, medicine, and environmental monitoring, as well as in the forensic sciences. It is a mobile source of neutron activity (20 Ci), yielding a small thermal neutron flux that is water moderated. The aim of this study is to develop a model to increase the neutron thermal flux of a source such as Am-Be. This study achieved multiple advantageous results: primarily, it will help us perform neutron activation analysis. Next, it will give us the opportunity to produce radio-elements with short half-lives. Am-Be single and multisource (5 sources) experiments were performed within an irradiation facility with a paraffin moderator. The resulting models mainly increase the thermal neutron flux compared to the traditional method with water moderator.

In this paper, we suggested the integration between automatic enforcement system and UTIS(Urban Traffic Information System) base station. UTIS base station and automatic enforcement system are different in the height of installation and the type of communication network. UTIS base station is 25 meter high and communicate with center system by optical network. Whereas automatic enforcement system is 6.6 meter high and communicate with center system by rental network. For the purpose of suggesting the efficient method of integration, research was as in the following. We found that the number of integrated system was 1,628 through the present state of analysis and UTIS equipment was satisfied with the required specifications through field testing. Also we suggested the appropriate configuration of the integrated system and analyzed that the cost of the integrated system installment is 1/5 lower than that of the legacy system installment.

The complexity of modern weapon systems using the intelligence technology demands that rapid and effective transition from force requirements to deployment and fielding. Thus this paper deals with the integration of development procedure, evolutionary acquisition, integrated test and evaluation, improvement of the requirements decision process, use of commercial products of high quality and low cost, specification deviation, and the effective use of dual use technology. In general, decision­makers, and military field users shall first consider the moving technology rapidly into use. This study is aimed to improve the defence acquisition management directive for timely force integration of weapon system.

This paper describes limitations and solutions of the existing processor-monitoring concept for a military supersonics aircraft Flight Control Computer (FLCC) equipped with modern architecture processor to perform the system integration test. Safecritical FLCC integration test, which requires automatic test for thousands of test cases and real-time input/output test condition generation, depends on the processor-monitoring device called Processor Interface (PI). The PI, which relies upon on the FLCC processor's external address and data-bus data, has some limitations due to multi-fetching capability of the modern sophisticated military processors, like C6000's VLIW (Very-Long Instruction Word) architecture and PowerPC's Superscalar architecture. Several techniques for limitations were developed and proper monitoring approach was presented for modem processor-adopted FLCC system integration test.

Delta-integration vectors were constructed for the purpose of achieving homologous integration of the hirudin expression cassette into the chromosome of Saccharomyces cerevisiae. A double $\delta$ system truncated with the unnecessary bacterial genes, and consequently having a reduced insert size for integration, showed a four-fold increase in transformation efficiency at given DNA concentrations, and as a result, the constructed recombinant yeast strain had a 1.3-fold enhancement in hirudin expression level compared with a single $\delta$ system.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced, and the Web services and ESB (Enterprise Service Bus) ate also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which is introduced in this paper, will be a good reference for future SOA implementation.

US DoD operated JCIDS(Joint Capability Integration and Development System) for top down requirement generation. Although the JCIDS can be a good practice for the countries which are trying to shift from bottom up to top down requirement generation, it contains many processes related with review and approval. In this study we structured a joint capability integration and development process from the JCIDS eliminating the organization dependent review or approval process so that it can be applied to any organization with some modification. Furthermore we implemented the process in the computer aided systems engineering tool, Cradle, for convenient use of the process. The result of this study can provide a basic process for top down capability development, and an efficient why of doing each element of the process using CASE tool.

Operational strategy for inventory control in the distribution system has been given attention. If an individual enterprise implements the strategy, it is not easy to gain scale merits because of limited quantity or burden of inventory. In this study, we propose an operational strategy for inventory control that considers managerial integration of regional distribution centers (RDCs) and present a model of it. In a network of several RDCs, they could share inventory information and supply parts for others in case of an inventory shortage. And a numerical example of the network is illustrated, which compares two operational strategies, integration management of RDCs and individual management of them. The result shows total cost reduction in the strategy of integration management through the efficient inventory control of multi-echelon distribution.
