An IPC(instrument panel Cluster) is a useful device that provides driving information to the driver. The information includes the vehicle speed, RPM, mileage, etc. The traditional IPC has been mostly implemented with mechanical technique. According to increment of needs for the convenience of IPC by user, the IPC must provide graphical interface and efficient driving information. Also the user-friendly IPC is needed by drivers. Thus flexible and robust software structure and development methods are required in order to develop IPC. In this paper, we propose software architecture and design method for the IPC using modeling method. We use MVC model and UML to model software architecture because they have flexible and robust characteristics. We can develop the various forms of information screen by separating views from model by using state diagram and class diagram in UML. Through this, the cost saving and ease of maintenance can be expected. The development time and cost can be reduced by using proposed method.

This study is investigates space syntax theory, developed by Bill Hiller, used for physical analysis and visual access of space and role of spatial configuration based on social logic. it mean computer program analyze physical structure of space and represent by mathematical logic. it used for predict space use and Descriptive of spatial configuration. This method and theory is incompletion for design, but it enough useful tool for architecture and urban design and will be improved. And development of a simple computer program - SSA(Sspace Syntax Analysis) for space syntax analysis and study. SSA is based on convex map analysis and using VISIO software for easily using and development.

The DGPS reference station is a national infrastructure generating GPS correctional information and transmitting the signal for Differential GPS. Currently, Korea has applied and operated the software-based DGPS reference station as a standard of the next generation proposed by the USCG in order to improve the hardware-based DGPS reference system. However, software-based DGPS reference station proposed by USCG was changed in software method, only for form. There is no advantage to changing software-based because the most critical part of architecture has not been improved. In this paper, we have designed a new software-based marine DGPS station architecture that a reference station software and a monitor station were integrated. The new marine DGPS station architecture based on software is a more simplified structure than it used to be and can be utilized in the DGPS reference station.

In recent years, embedded systems have become so complex and the development time to market is required to be shorter than before. As embedded systems include more functions for new services, embedded software gradually grow in size, and development costs and time are increasing. In order to overcome this serious matter, we need a customized design and test technique for embedded software. In this paper, we present a software architecture style for embedded software. It facilitates the composition of reusable functions and helps developers to reduce development time. Because the costs associated with revealing errors of embedded software in applications are rising. we propose a test method and tools for target environments.

Land suitability method has become a standard part of planning analysis at many scales. GIS computer packages have been developed for this purpose. But those are still expensive and hard to learn, and also have limits to extend the results to a landscape design. For the relatively simple tasks and CAD-related works, an application of CAD software for the suitability analysis is very useful and easy to handle. For the purpose, this study develops a technique for suitability analysis, using vector based microcomputer CAD softwares.

In the network-based game where it uses the Internet infrastructure, the implementation is possible with the various methods. Such Applications are developed in the multi-tired architecture. There are many cases for the server to be separated from the hardware or the software. In this case, a lot of applications make the distributed process possible and are made as the multi-tiered architecture to develop the reusability of the existing software module. Especially, it is mostly general to separate for the case of a database server to a new tier. One of the important points of multi-tiered server side applications is security and because of this, it is difficult to share the related data about the design skill. Using design patterns, it gives help in reusing the existing written-code for the design of the game that needs a lot of money and time. Design Patterns are related to the software reuse. For the development of more efficient games, if well-defined design patterns are provided to the developers, then it would make more easy advanced game API and make possible the framework for the game development based on the API Through the analysis of the general network-based game currently servicing in the Internet, in this paper, we discuss how to implement a business logic tier using database system among the server side architectures. The main objective of this article is to show an efficient APIs(Application Programming Interfaces) design method which can be used to manage the data that must be saved to the database system among the packets that client/server have to be exchange.

Software Architecture for any given software system is its skeletal framework. That is to say that if this framework does not properly support the system then it would cause more harm than good. Accordingly it is our opinion that choosing the right architecture to realize this framework is a crucial part in creating a successful system. This report discusses a comparative method which utilizes the steps in ATAM to realize architectural decisions and more importantly aide in architectural selection that promotes system success.

When we conduct development of a large-size SI project, it is highly necessary to utilize an appropriate application framework which helps to build a qualified software with high productivity in a short period of time. In this paper, we propose the architecture of a dynamically reconfigurable CBD application integration framework that has been used for developing large-scale e-business applications to achieve high development productivity and maintainability. This Integration framework can easily extend its functionalities, and dynamically change its configuration during run time according to the business category, such as applying interaction patterns among main components in software architecture, rules, policies, and environmental parameters. Dynamic reconfiguration has the feature to make applications be easily customized for changeable requirements. Through our application integration framework, huge sizes of contents can be managed according to the business category as well, by keeping configuration informations and huge volumes of source codes. In order to evaluate out application integration framework in terms of performance criteria, we present experimental results of throughputs from the framework by yielding dynamic configuration without any performance degradation.

The aircraft manufacturers are constantly driving to reduce manufacturing lead times and cost at the same time as the product complexity increases and technology continues to change. Integrated Modular Avionics (IMA) is a solution that allows the aviation industry to manage their avionics complexity. IMA defines an integrated system architecture that preserves the fault containment and 'separation of concerns' properties of the federated architectures. In software side, the air transport industry has developed ARINC 653 specification as a standardized Real Time Operating System (RTOS) interface definition for IMA. It allows hosting multiple applications of different software levels on the same hardware in the context of IMA architecture. This paper describes a study that provided the avionics software design for separation of fault and backup of core function to reduce workload of pilot with cost efficiency.
