This paper describes a model-based software development methodology for AUTOSAR-ready light software architecture(AUTOSAR-Lite). The proposed methodology briefly represents an application software modeling technique using Matlab/Simulink. Using the proposed technique, application software architecture elements (e.g. software components, runnables, and interfaces) and functional behaviors can be designed in a single modeling environment. From the designed model, the codes of application software is automatically generated using Real-Time Workshop Embedded Coder. The generated application software is easily integrated with hand-coded basic software using the proposed method. In order to evaluate the proposed methodology, a diesel engine management system for a passenger car was employed as a case study. Based on the methodology, 8 atomic software components and 52 runnables are successfully developed, and they are evaluated by engine experiments. From this case study, AUTOSAR compatible model-based application software was successfully developed, and the effectiveness of the proposed methodology was evaluated.

Coarse-Grained Reconfigurable Architecture (CGRA) is a very promising platform that provides fast turn-around-time as well as very high energy efficiency for multimedia applications. One of the problems with CGRAs, however, is application mapping, which currently does not scale well with geometrically increasing numbers of cores. To mitigate the scalability problem, this paper discusses how to use the SIMD (Single Instruction Multiple Data) paradigm for CGRAs. While the idea of SIMD is not new, SIMD can complicate the mapping problem by adding an additional dimension of iteration mapping to the already complex problem of operation and data mapping, which are all interdependent, and can thus significantly affect performance through memory bank conflicts. In this paper, based on a new architecture called SIMD reconfigurable architecture, which allows SIMD execution at multiple levels of granularity, we present how to minimize bank conflicts considering all three related sub-problems, for various RA organizations. We also present data tiling and evaluate a conflict-free scheduling algorithm as a way to eliminate bank conflicts for a certain class of mapping problem.

This paper presents AUTOSAR-ready light software architecture (AUTOSAR-Lite), which is a light weighted version of the AUTOSAR, for automotive embedded control systems. The proposed AUTOSAR-Lite reduces overhead problems caused by the excessive standard specifications of AUTOSAR. Concurrently, AUTOSAR-Lite keeps advantages of AUTOSAR such as a scalability, re-usability, reliability, and transferability. The fundamental design of AUTOSAR-Lite is originated from the AUTOSAR standard. AUTOSAR-Lite is composed of three layers such as an application software, runtime environment, and basic software layer. The application software layer adopts component-based design methodology as AUTOSAR. The runtime environment layer integrates interfaces between application and basic software layers. In case of the basic software layer, restrictions of the module configurations and interfaces of basic software are minimized. In order to validate the feasibility of AUTOSAR-Lite, a software design result based on AUTOSAR-Lite software architecture for electronic throttle control (ETC) system is suggested.

Modern enterprise may be in need of developing the right application programs under rapidly changing business environment in fast time-to-market. But Most of enterprise without business process mechanism are very hard to develop the application needed in time when it will be changing their business. To solve this problem, we propose the business process framework based on the closed architecture. This approach is to develop the right application with reusing software modules in time and easily under rapid business process changing/improving through mapping BPM(Business Process Model), SOA(Service Oriented Architecture), and CBD(Component Based Development). we also define 5-Layers of BPF(Business Process Framework), and BNF(Backus Naur Form) for structuring BPF.

This study is to use B.F. certification standards to identify the application and differences of B.F. facilities according to various approaches, and to use the analysis results as basic data for the expansion and renovation of new facilities, the National University (Jeonnam University Library), which underwent remodeling before the implementation of the certification system, and the two newly established private universities (Joseon University Library) that were subject to legal application before the implementation of the certification system. First, Chosun University met more B.F. certification standards than Chonnam National University, and mainly intermediary facilities belonged to the best to the best. Second, Chosun University and Chonnam National University's internal facilities met many B.F. certification standards, and Chonnam National University had many areas to improve and found areas to remodel. Third, information facilities at Chonnam National University and Chosun University only had facilities for the hearing impaired, and there were no information facilities for the visually impaired. Facilities for the visually impaired had to be installed, and compared to Chosun University, Chonnam National University fell short of the B.F. certification standard, so there were many areas that needed to be remodeled.

Ubiquitous Computing은 소프트웨어 Architecture를 구현하는데 있어서 많은 도전들을 필요로 한다. 그 중에 하나는 User가 한 컴퓨터에서 다른 컴퓨터로 이동할 경우의 User Mobility를 고려한 것으로 User뿐 아니라 Application도 같이 이동하여 예전의 컴퓨팅 환경을 그대로 복원하게 되며 User가 작업하던 뜯을 계속해서 할 수 있게 만드는 것이다. 본 논문은 이러한 Ubiquitous Computing 환경을 만들기 위해 MuSa Architecture를 제안하고, Application 이동에 필요한 Manager들을 설명하도록 한다.

The result of this study about application methods of regional heritage are important things. 1. Rural community going ahead Rural Activation Policies applied in regional heritage, have principal experience programs based on visiter's demands. 2. The programs applied regional heritage are most useful application methods of traditional-cultural experience, and following, folk-life and nature environment experience. 3. Insufficient of scheme for applying regional heritage, and specific characters and identity of rural community, is coming out the inadequate plan of community design with comparing other neighborhoods.

Recently, as both business processes and IT systems become ever more complex. Especially, enterprise applications tend to become unmanageably complex and increasingly costly to maintain. Therefore complexity is the insidious enemy of software development. It is critical to have a methodology that recognizes and manages this enemy effectively. In this paper, we propose ISIS (Integrated System of Independent Subsystems) - the architectural style needed to develop the complex enterprise applications. The ISIS was developed to meet the challenge of reducing the complexity of a larger enterprise application today. It gives us architecture models for reducing development complexity and composite application. The enterprise application is partitioned into a collection of independent subsystems using ISIS decomposition schemes and equivalence relations. We use middleware named ISIS engine that provides a service for subsystems interoperability by enabling the integration of distributed, cross-platform subsystems. We have implemented an ITSM system that achieves our objectives, reducing development complexity, using the ISIS architecture. Finally, ISIS architecture provides greater flexibility and productivity when an organization needs either to change its business processes, or to update the underlying systems.
