Amount of biological data information has been increasing exponentially. In order to cope with this bio-information explosion, it is necessary to construct a biological data information integration system. The integration system could provide useful services for bio-application developers by answering general complex queries that require accessing information from heterogeneous bio data sources, and easily accommodate a new database into the integrated systems. In this paper, we analyze architectures and mechanisms of existing integration systems with their advantages and disadvantages. Based on this analysis and user requirement studies, we propose an integration system framework that embraces advantages of the existing systems. More specifically, we propose an integration system architecture composed of a mediator and wrappers, which can offer a service interface layer for various other applications as well as independent biologists, thus playing the role of database management system for biology applications. In other words, the system can help abstract the heterogeneous information structures and formats from the application layer. In the system, the wrappers send database-specific queries and report the result to the mediator using XML. The proposed system could facilitate in silico knowledge discovery by allowing combination of numerous discrete biological information databases.

A parallel integration approach is proposed for real-time simulation of controlled mechanical systems. The proposed approach, which employs the dual-rate integration method in a parallel computing environment, is developed to deal with stiffness and high frequency characteristics of the controlled mechanical systems effectively. Numerical experiments are performed to demonstrate the effectiveness of the approach in shared memory multiprocessors, Alliant FX/8 and Alliant FX/80.

This paper presents a component-based integration framework and its software component architecture for supporting the rapid integration of legacy design supporting systems in the distributed environment. Also, using standard interface, this software component architecture provides flexibility, extensibility and compatibility which ensure software components to be independent of the integration middleware and systems to be integrated.

The INS/GPS integration system is designed by employing an adaptive filter that can estimate the measurement noise variance using the residual of the filter. To verify the efficiency of the proposed loosely-coupled INS/GPS integration system, simulation is performed by assuming that GPS information has large position errors. Simulation results show that the proposed integration system with the adaptive filter is more effective in estimating the position and attitude errors than those with the Extended Kalman Filter.

Supply chain management (SCM) aims to provide the coordination and execution of planning and decision-making in multi organization-wide production and distribution. The advancement of information technology and the globalization of market promote SCM integration. Information sharing has become a major driver of competitive advantage in SCM. In this research, we aim to analyze the influence of SCM integration on firm performance and the role of information sharing between SCM integration and firm performance. Of the 750 questionnaires posted, a total of 218 questionnaires were collected after one follow-up. A total of 199 questionnaires were analyzed after 19 questionnaires were eliminated due to largely missing values. We used structural equation modeling technique to validate the causal relationship between SCM integration, information sharing, and firm performance. The results suggest that improved SCM integration both within the focal company (intra-organization) and across companies (inter-organization) enhances firm performance positively. Information sharing acts as a mediator between the SCM integration and the firm performance. Intra-organization SCM integration is positively related to inter-organization SCM integration, namely, SCM integration with suppliers and customers. The results suggest that internal integration of SCM significantly influences external integration with customers and suppliers. The result also shows that supply chain integration has a positive influence on firm performance and information sharing positively impacts firm performance as well.

The purpose of this paper is to provide an understanding of building systems and to propose methods of building system analysis and integration. Building components are classified into four major systems; structure, mechanical, envelope, and interior system. There are 11 combinations between major systems. Three integration modes(physical, visual, and functional integration) and 12 integration strategies are proposed. A case study of Richards Medical Research Buildings designed by Louis I. Kahn was conducted from the perspective of building system analysis and integration.

Due to the development and proliferation of internet technology, cooperation and interaction between companies have become very important. However, different heterogeneous systems have been used as information systems for companies because of various types of pressure in the business environment. Therefore, business process integration and interaction are recognized as essential elements, not optional elements. In addition, it is important to make a business process which is valuable as an intellectual property in a storable form and share. So, many business process languages for service integration and GUI type's automatic systems using the same and making business process easily have been introducing. However, to integrate previously created web service[1] workflows, or to use a web service workflow for another workflow production like an activity, that is, research to support multi integration language and system is not ongoing except for research to make and connect adapter between workflow engines.[2] Also, research for current languages and systems that integrate the BPEL[3] process into a workflow in the industrial world does not exist. This means that integration between workflows being used at companies is difficult, and becomes the biggest obstacle to service integration, which is necessary for cooperation and interaction between companies. To solve this problem, in this paper, I defined BPIL based on XML[4], which can store business processes. Also, using this, BPIL workflow system based on SOA[5] which supports multiple integration and workflow profiling was designed and prototype was embodied.

This work presents the relationship between the domains of Human Factors Integration(HFI) to develop the weapon systems through integrating human factors into the defense acquisition program. The HFI is a systematic process for identifying, tracking and resolving human related issues ensuring a balanced development of both technologies and human aspects of capability. In this point of view, this paper identifies and analyzes the HFI domains. Based on the results, this paper presents the relationships between the domains of the HFI.

Three structure-dependent integration methods with no numerical dissipation have been successfully developed for time integration. Although these three integration methods generally have the same numerical properties, such as unconditional stability, second-order accuracy, explicit formulation, no overshoot and no numerical damping, there still exist some different numerical properties. It is found that TLM can only have unconditional stability for linear elastic and stiffness softening systems for zero viscous damping while for nonzero viscous damping it only has unconditional stability for linear elastic systems. Whereas, both CEM and CRM can have unconditional stability for linear elastic and stiffness softening systems for both zero and nonzero viscous damping. However, the most significantly different property among the three integration methods is a weak instability. In fact, both CRM and TLM have a weak instability, which will lead to an adverse overshoot or even a numerical instability in the high frequency responses to nonzero initial conditions. Whereas, CEM possesses no such an adverse weak instability. As a result, the performance of CEM is much better than for CRM and TLM. Notice that a weak instability property of CRM and TLM might severely limit its practical applications.
